PRELIMINARY PROXY STATEMENT/PROSPECTUS

SUBJECT TO COMPLETION — DATED JUNE 16, 2011



Skyworks Solutions, Inc. 20 Sylvan Road Woburn, MA 01801		Advanced Analogic Technologies Incorporated 3230 Scott Boulevard Santa Clara, CA 95054

PROSPECTUS		PROXY STATEMENT

A Merger Proposal — Your Vote Is Very Important

To the Stockholders of Advanced Analogic Technologies Incorporated:

On May 26, 2011, the board of directors of Advanced Analogic Technologies Incorporated (“AATI”) unanimously approved a merger agreement among AATI, Skyworks Solutions, Inc. (“Skyworks”) and PowerCo Acquisition Corp. (“Merger Sub”) that contemplates the merger of Merger Sub with and into AATI, with AATI surviving the merger as a wholly owned subsidiary of Skyworks. AATI is sending you this proxy statement/prospectus to ask you to vote for the adoption of the merger agreement and the approval of the merger. If AATI stockholders adopt the merger agreement and approve the merger and the parties subsequently complete the merger, each outstanding share of AATI common stock will become the right to receive a combination of cash and Skyworks common stock with a nominal total combined value of $6.13, consisting of 0.08725 of a share of Skyworks common stock, par value $0.25 per share (the “stock consideration”), and cash (the “cash consideration” and, together with the stock consideration, the “merger consideration”) in the initial calculated amount of $3.68, without interest, less applicable withholding taxes, and subject to adjustment as provided in the merger agreement and further described in the proxy statement/prospectus.

After careful consideration, AATI’s board of directors has unanimously determined that it is advisable and in the best interests of the stockholders of AATI for AATI to enter into the merger agreement and to consummate the merger and the transactions contemplated by the merger agreement, and that the merger consideration provided in the merger agreement is fair to the stockholders of AATI who will be entitled to receive such merger consideration. AATI’s board of directors unanimously recommends that you vote “FOR” the adoption of the merger agreement and approval of the merger. The merger cannot be completed unless the holders of at least a majority of all the votes entitled to be cast by holders of outstanding shares of AATI common stock vote to adopt the merger agreement and approve the merger.

Whether or not you plan to attend the special meeting of stockholders, please take time to vote over the Internet, by telephone or by completing the enclosed proxy card and mailing it in accordance with the instructions on the card. THE FAILURE OF ANY STOCKHOLDER TO VOTE WILL HAVE THE SAME EFFECT AS A VOTE BY THAT STOCKHOLDER AGAINST THE ADOPTION OF THE MERGER AGREEMENT AND AGAINST APPROVAL OF THE MERGER. WHETHER OR NOT YOU PLAN TO ATTEND THE SPECIAL MEETING IN PERSON, WE REQUEST THAT YOU COMPLETE, SIGN, DATE AND RETURN THE ENCLOSED PROXY CARD OR SUBMIT YOUR PROXY BY TELEPHONE OR OVER THE INTERNET PRIOR TO THE SPECIAL MEETING TO ENSURE THAT YOUR SHARES WILL BE VOTED AT THE SPECIAL MEETING. AATI common stock and Skyworks common stock trade on The Nasdaq Global Select Market under the symbols “AATI” and “SWKS,” respectively.

The accompanying proxy statement/prospectus provides you with detailed information about the special meeting, the merger agreement and the merger. A copy of the merger agreement is attached as Annex A to the accompanying proxy statement/prospectus. You are encouraged to read carefully the accompanying proxy statement/prospectus in its entirety including the section entitled “Risk Factors” beginning on page 11.

You may also obtain more information about AATI and Skyworks from documents that each has filed with the Securities and Exchange Commission.

Sincerely,

Richard K. Williams

QUESTIONS AND ANSWERS ABOUT THE SPECIAL MEETING AND THE MERGER

The following questions and answers are intended to address briefly some questions you may have regarding the special meeting and the proposed merger. These questions and answers may not address all questions that may be important to you as a stockholder. Please refer to the more detailed information contained elsewhere in this proxy statement/prospectus, as well as the additional documents to which this proxy statement/prospectus refers or which it incorporates by reference, including the merger agreement, a copy of which is attached to this proxy statement/prospectus as Annex A. See “Where You Can Find More Information” for the location of information incorporated by reference into this proxy statement/prospectus.


Q:		*Why am I receiving this proxy statement/prospectus?*

A:		AATI and Skyworks have agreed to the acquisition of AATI by Skyworks under the terms of the merger agreement described in this proxy statement/prospectus. You are receiving this document because you were a stockholder of record of the AATI on the record date for the AATI special meeting at which AATI stockholders will vote on the merger. You may also be receiving this proxy statement/prospectus because your shares of AATI are held on your behalf by a broker, bank or other nominee. If your shares of AATI are held on your behalf by a broker, bank or other nominee, you are the beneficial owner of such shares, but the broker, bank or other nominee is the stockholder of record and your shares are referred to as being held in “street name.”

		The acquisition of AATI cannot be completed without the approval of AATI stockholders and AATI is seeking your approval. Under the merger agreement, AATI will become a wholly owned subsidiary of Skyworks and will no longer be a publicly held corporation. In the merger, Skyworks will pay a cash amount and will also issue shares of Skyworks common stock as part of the consideration to be paid to holders of AATI common stock.

		We are delivering this document to you as both a proxy statement of AATI and a prospectus of Skyworks. It is a proxy statement because the AATI board of directors is soliciting proxies from AATI stockholders to vote for the adoption of the merger agreement and the approval of the merger and the other transactions contemplated by the merger agreement at the special meeting being held to consider and vote upon the merger agreement and the other matters described in the notice of the meeting and described in this proxy statement/prospectus. Your proxy will be used at the meeting and at any adjournment or postponement of the meeting. It is a prospectus because Skyworks will issue Skyworks common stock to AATI stockholders as part of the consideration to be paid in the merger.

Q:		*What am I being asked to vote on?*

A:		At the special meeting, AATI common stockholders will be asked (1) to adopt the merger agreement and to approve the merger, (2) to approve, by non-binding, advisory vote, certain compensation arrangements for AATI’s named executive officers and directors in connection with the merger and (3) to approve the adjournment of the special meeting for the solicitation of additional proxies in the event there are insufficient votes present, in person or represented by proxy, at the time of the special meeting to approve and adopt the merger agreement.

Q:		*What will AATI common stockholders receive in the merger?*

A:		Upon completion of the merger, each outstanding share of AATI common stock (except for shares held directly or indirectly by Skyworks, Merger Sub, AATI or any wholly owned subsidiary of AATI, and except for shares of AATI common stock held by stockholders exercising dissenter’s rights) will automatically become the right to receive an aggregate of $6.13 per share, payable in the form of 0.08725 of a share of Skyworks common stock (the “stock consideration”) and an adjustable cash amount in the initial calculated amount of $3.68 (the “cash consideration” and, together with the stock consideration, the “merger consideration”), without interest and less applicable withholding taxes. The amount of stock was based on the average last sale price of Skyworks common stock (at the 4 p.m. Eastern Time end of Nasdaq regular trading hours) over the 30-trading days prior to May 26, 2011. At that average price, the stock consideration had a nominal value of $2.45 and the nominal aggregate combined value of the cash

iii


		consideration and the stock consideration was $6.13. The final cash consideration will depend on the closing value of the stock consideration, calculated on the basis of Skyworks’ average reported last sale price in regular Nasdaq trading during a five-trading-day measurement period preceding the closing of the merger. If the closing value of the stock consideration is less than $2.45, the cash consideration will increase by the amount of the shortfall. If the closing value of the stock consideration is more than $2.45, the cash consideration will decrease by the amount of the excess. And if the closing value of the stock consideration is exactly $2.45, the cash consideration will remain unchanged at $3.68. In each case, the merger consideration will maintain a constant nominal aggregate combined value of $6.13 per share of AATI common stock.

		For example:

		• if Skyworks’ average reported last sale price in the pre-closing measurement period is $26.50, then the closing value of the stock consideration would be $2.31 and the cash amount would increase by $0.14 (the amount of the shortfall between $2.31 and $2.45), from $3.68 to $3.82; and

		• if Skyworks’ average reported last sale price in the pre-closing measurement period is $30.00, then the closing value of the stock consideration would be $2.62 and the cash amount would decrease by $0.17 (the amount of the excess of $2.62 over $2.45), from $3.68 to $3.51.

		In addition, you should note that if Skyworks’ average last reported sale price during the pre-closing measurement period is less than $21.00, Skyworks has the right to pay the entire $6.13 in cash, and in that event, AATI stockholders would not receive any shares of Skyworks common stock in the merger for their outstanding shares of AATI common stock, and would instead receive $6.13 entirely in cash.

		As a result of these adjustments and provisions, AATI stockholders will not capture or suffer the full economic consequences (whether positive or negative) that may result from changes in the trading price of Skyworks common stock between May 26, 2011 (the date of the merger agreement) and their receipt of Skyworks common stock in the merger. In addition, the exact market value of the shares of Skyworks common stock that AATI stockholders receive in the merger will depend on the market value of shares of Skyworks common stock at the time they actually receive those shares and could vary significantly from the market value of shares of Skyworks common stock on the date the merger agreement was executed, the date of this proxy statement/prospectus, or the date of the special meeting, and could also vary significantly from any of the average prices used in the calculations of the stock consideration and the cash consideration.

		No fractional shares of Skyworks will be issued in connection with the merger. Instead, an AATI stockholder who otherwise would have received a fraction of a share of Skyworks common stock will receive an amount in cash rather than a fractional share. This cash amount will be determined by multiplying the fraction of a share of Skyworks common stock that the holder would otherwise receive by the average of the last reported sale price of Skyworks common stock (at the 4 p.m. Eastern Time end of Nasdaq regular trading hours) during the ten consecutive trading days ending on the last trading day prior to the effective time of the merger. See “The Merger Agreement — The Merger Consideration.”

Q:		*Is the merger taxable to AATI stockholders for U.S. federal income tax purposes?*

A:		The receipt of Skyworks common stock and cash in exchange for AATI common stock in the merger will be a taxable transaction for U.S. federal income tax purposes. A U.S. holder (as defined below) who receives Skyworks common stock and cash in the merger will generally recognize capital gain or loss equal to the difference, if any, between (1) the sum of the fair market value of Skyworks common stock as of the effective time of the merger and the amount of cash received, including any cash received in lieu of fractional shares of Skyworks common stock, received in the merger, and (2) such holder’s adjusted tax basis in its AATI common stock exchanged for cash and Skyworks stock in the merger. Please carefully review the information set forth in the section entitled “The Merger — Material U.S. Federal Income Tax Consequences of the Merger,” for a description of the material U.S. federal income tax consequences of the merger. The tax consequences of the merger to you will depend on your own situation. Please consult your tax advisors for a full understanding of the tax consequences of the merger to you.


Q:		*How does AATI’s board of directors recommend that I vote on the proposals?*

A:		The board of directors of AATI unanimously recommends that you vote “FOR” the adoption of the merger agreement and the approval of the merger, “FOR” the non-binding, advisory proposal regarding certain merger-related executive compensation arrangements and “FOR” the adjournment, if necessary, of the special meeting to solicit additional proxies in favor of adoption of the merger agreement and approval of the merger.

Q:		*Are there risks that I should consider in deciding whether to vote for the merger?*

A:		Yes. In evaluating the merger, you should consider carefully the factors discussed in the section entitled “Risk Factors.”

Q:		*What are the conditions to completion of the merger?*

A:		The obligations of AATI and Skyworks to complete the merger are subject to the following conditions (among others):

		• the adoption of the merger agreement and the approval of the merger by AATI’s stockholders;

		• the expiration or termination of the applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), if any, and applicable foreign laws;

		• the receipt of all approvals of, and the completion of all filings with, any governmental entity in connection with the merger and the other transactions contemplated by the merger agreement, the expiration or termination of all waiting periods, and the absence of any material condition to the receipt or issuance of such approvals or the expiration or termination of those waiting periods;

		• the absence of any order, executive order, stay, decree, judgment or injunction (preliminary or permanent) or statute, rule or regulation by any governmental entity which is in effect and which has the effect of making the merger illegal or otherwise prohibiting or imposing any material condition on the consummation of the merger or the other transactions contemplated by the merger agreement;

		• the filing with Nasdaq (if required) of a notification for listing of the shares of Skyworks common stock to be issued in the merger; and

		• the effectiveness under the Securities Act of 1933, as amended (the “Securities Act”), of the registration statement, of which this proxy statement/prospectus forms a part, and the absence of any pending or threatened stop order suspending the effectiveness of such registration statement.


		In addition, Skyworks’ obligation to complete the merger is subject to the following additional conditions:

		See “The Merger Agreement — Conditions to the Merger.”


Q:		*What will happen if the merger is not completed?*

A:		If AATI stockholders do not adopt the merger agreement and approve the merger, or the parties do not complete the merger for any other reason, you will not receive any payment for your shares of AATI common stock in connection with the merger. Instead, AATI will remain an independent public company, and its common stock will continue to be listed and traded on Nasdaq. There is no guarantee, however, that as an independent public company, AATI’s stock price will remain at its present value, and if the pending merger is not consummated, AATI’s stock price may substantially decline. In certain circumstances, AATI may be required to pay Skyworks a termination fee of $8.5 million or to reimburse Skyworks for up to $500,000 of fees and expenses Skyworks has incurred in connection with the proposed merger, as described under “The Merger Agreement — Transaction Fees and Expenses; Termination Fee.”

Q:		*Are there any other matters to be addressed at the meeting?*

A:		AATI is not aware of any other business to be acted upon at the special meeting. If, however, other matters are properly brought before the special meeting, your proxies will have discretion to vote or act on those matters according to their best judgment, and they intend to vote the shares as the AATI board of directors may recommend.

Q:		*When is this proxy statement/prospectus being mailed?*

A:		This proxy statement/prospectus and the related proxy card are first being sent to AATI stockholders on or about [ • ], 2011.

Q:		*When and where will the special meeting be held?*

A:		The special meeting will take place at [ • ] Pacific daylight time on [ • ], 2011, at the offices of Wilson Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo Alto, California 94304.

Q:		*Who is entitled to vote at the special meeting?*

A:		Holders of record of outstanding shares of AATI common stock as of the close of business on [ • ], 2011, the record date for the special meeting, are entitled to receive notice of, attend and vote or be represented by proxy at the special meeting and any adjournment or postponement of the special meeting. If the special meeting is postponed or adjourned the AATI board of directors may fix a new record date for any such postponed or adjourned meeting under certain circumstances. Each share of AATI common stock outstanding as of the close of business on the record date is entitled to one vote on each matter properly brought before the special meeting. If a broker or other nominee holds your shares, then you are not the holder of record and you must ask your broker or other nominee how you can vote in person at the special meeting. See “The Special Meeting — Proxies and Revocation.”


Q:		*Who may attend the special meeting?*

A:		AATI stockholders (or their authorized representatives) and AATI’s invited guests may attend the special meeting.

Q:		*How do I vote my shares at the special meeting if I am a record holder of shares of AATI common stock?*

A:		If you are a holder of record of AATI common stock as of the close of business on [ • ], 2011, the record date for the special meeting, you may authorize a proxy to vote your shares at the special meeting or you may vote your shares in person at the special meeting. However, AATI encourages you to submit a proxy before the special meeting, even if you plan to attend the special meeting. You can authorize your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed, postage-paid envelope and in accordance with the instructions on the proxy card or, if you prefer, by telephone or over the Internet by following the instructions on the enclosed proxy card.

Q:		*How do I vote my shares at the special meeting, if my shares of AATI common stock are held in “street name?”*

A:		If your shares are held in an account at a broker or another nominee, you must instruct the broker or such other nominee on how to vote your shares by following the instructions that the broker or other nominee provides to you with these materials. Most brokers offer the ability for stockholders to submit voting instructions by mail by completing a voting instruction card, by telephone or over the Internet.

		If you do not provide instructions to your broker or other nominee, your shares will not be voted on any proposal on which your broker or other nominee does not have discretionary authority to vote. This is called a broker non-vote. Brokers will not have discretionary authority to vote on the proposal to adopt the merger agreement. A broker non-vote will have the same effect as a vote “AGAINST” the adoption of the merger agreement and approval of the merger.

		If you hold shares through a broker or other nominee and wish to vote your shares in person at the special meeting, you must obtain a proxy from your broker or other nominee and present it to the inspector of election with your ballot when you vote at the special meeting.

Q:		*Why is my vote important?*

A:		If you do not return your proxy card, submit your proxy by telephone or over the Internet or vote in person at the special meeting, it will be more difficult for AATI to obtain the necessary quorum to hold its special meeting and obtain the necessary stockholder votes to adopt the merger agreement and to approve the merger. In addition, your failure to return a proxy card, submit a proxy by telephone or over the Internet or vote in person at the special meeting will have the same effect as a vote “AGAINST” the adoption of the merger agreement and the approval of the merger.

Q:		*What constitutes a quorum for the meeting?*

A:		A majority of the votes entitled to be cast by holders of issued and outstanding shares of AATI common stock must be present or represented by proxy to constitute a quorum for action on the matters to be voted upon at the special meeting. All shares of AATI common stock represented at the special meeting, including abstentions and broker non-votes, will be treated as present for purposes of determining the presence or absence of a quorum for all matters voted on at the special meeting.

Q:		*What vote of AATI’s stockholders is required to adopt the merger agreement and to approve the merger, or to approve an adjournment of the special meeting?*

A:		The affirmative vote of at least a majority of all of the votes entitled to be cast by holders of all shares of AATI common stock that are issued and outstanding as of the record date for the special meeting is required to adopt the merger agreement and to approve the merger. If a quorum is present, approval of the proposal to adjourn the special meeting to solicit additional proxies requires the votes cast favoring the action to exceed the votes cast opposing the action.

vii


Q:		*What vote of AATI’s stockholders is required to approve the non-binding, advisory proposal regarding certain merger-related executive compensation arrangements?*

A:		Approval of the non-binding, advisory proposal regarding certain merger-related executive compensation arrangements requires the affirmative vote of holders of a majority of the shares of AATI common stock present in person or represented by proxy at the special meeting and entitled to vote thereon. Stockholders should note that the proposal regarding certain merger-related executive compensation arrangements is merely an advisory vote which will not be binding on AATI, Skyworks or AATI’s board of directors.

Q:		*What will happen if I abstain from voting or fail to vote?*

A:		With respect to the proposal to adopt the merger agreement and to approve the merger, if you abstain from voting on the proposal, fail to cast your vote in person or by proxy or if your shares are held by your broker or other nominee (i.e., in “street name”) and you fail to give voting instructions to your broker or other nominee on how to vote your shares, it will have the same effect as a vote “AGAINST” the proposal to adopt the merger agreement and to approve the merger.

		With respect to the non-binding, advisory proposal regarding certain merger-related executive compensation, abstaining will have the same effect as a vote “AGAINST” the non-binding, advisory proposal regarding certain merger-related executive compensation arrangements. If you fail to cast your vote in person or by proxy or if you hold your shares in “street name” and fail to give voting instructions to your broker or other nominee on how to vote your shares, your shares will not be counted as shares present and entitled to vote and will have no effect on the proposal.

		With respect to the proposal to approve any adjournment of the special meeting for the purpose of soliciting additional proxies, if you abstain from voting on the proposal, fail to cast your vote in person or by proxy or if you hold your shares in “street name” and fail to give voting instructions to your broker or other nominee on how to vote your shares, it will not have any effect on the outcome of the vote on that proposal.

Q:		*How will proxy holders vote my shares of common stock?*

A:		If you properly authorize a proxy prior to the special meeting, your shares of common stock will be voted as you direct. If you authorize a proxy but no direction is otherwise made, your shares of common stock will be voted “FOR” the proposal to adopt the merger agreement and to approve the merger, “FOR” the non-binding, advisory proposal regarding certain merger-related executive compensation and “FOR” the proposal to approve any adjournments of the special meeting for the purpose of soliciting additional proxies. The proxy holders will vote in their discretion upon such other matters as may properly come before the special meeting by or at the direction of AATI’s board of directors or any adjournment or postponement of the special meeting.

Q:		*What happens if I sell my shares of common stock before the special meeting?*

A:		If you hold your shares of AATI common stock as of the close of business on the record date but transfer them after the record date and before the special meeting, you will retain your right to vote at the special meeting (provided that such shares remain outstanding on the date of the special meeting), but you will not have the right to receive the merger consideration for the shares. In order to receive the merger consideration, you must hold your AATI shares through completion of the merger.

Q:		*Can I change my vote?*

A:		Yes. If you own shares of common stock as a record holder as of the close of business on the record date, you may revoke a previously authorized proxy at any time prior to its exercise by delivering a properly executed, later-dated proxy card, by authorizing your proxy by telephone or over the Internet at a later date than your previously authorized proxy, by filing a written revocation of your proxy with AATI’s Corporate Secretary or by voting in person at the special meeting. Attendance at the meeting will not, in itself, constitute revocation of a previously authorized proxy. If you own shares of common stock in “street name,”

viii


		you may revoke or change previously granted voting instructions by following the instructions provided by the broker or other nominee that is the registered owner of the shares.

Q:		*Should I send in my AATI stock certificates now?*

A:		No. You should not send in any stock certificates at this time. Shortly after the merger becomes effective, you will receive a letter of transmittal with instructions informing you how to send your share certificates to the exchange agent in order to receive the merger consideration. You should use the letter of transmittal to exchange shares of AATI common stock for the merger consideration to which you are entitled as a result of the merger.

Q:		*Am I entitled to dissenters’ rights?*

A:		Yes. Under Delaware law, the holders of AATI common stock are entitled to dissenters’ rights in connection with the merger and are entitled to seek appraisal of their shares by the Delaware Court of Chancery.

Q:		*When do you expect to complete the merger?*

A:		AATI and Skyworks are working towards completing the merger promptly. AATI and Skyworks currently expect to complete the merger in the third quarter of calendar 2011, subject to receipt of AATI’s stockholder adoption of the merger agreement and satisfaction of other closing conditions set forth in the merger agreement. However, no assurance can be given as to when, or if, the merger will occur.

Q:		*What will happen to the common stock that I currently own after completion of the merger?*

A:		Following the completion of the merger, your shares of AATI common stock will be cancelled and will represent only the right to receive the merger consideration. Trading in AATI common stock on Nasdaq will cease, and price quotations for AATI common stock will no longer be available.

Q:		*Where can I find more information about AATI and Skyworks?*

A:		You can find more information about AATI and Skyworks from various sources as described under “Sources of Additional Information” and “Where You Can Find More Information.”

Q:		*Who will solicit and pay the cost of soliciting proxies?*

A:		AATI will bear the cost of soliciting proxies for the special meeting. The AATI board of directors is soliciting your proxy on behalf of AATI. AATI’s directors, officers and employees may solicit proxies by telephone and facsimile, by mail, over the Internet or in person. They will not be paid any additional amounts for soliciting proxies. AATI has retained Innisfree M&A Incorporated (“Innisfree”) to assist it in the solicitation of proxies. AATI expects to pay Innisfree a fee not to exceed $20,000 for its services. AATI will also pay additional fees to Innisfree depending upon the extent of additional services requested by AATI and reimburse Innisfree for expenses it incurs in connection with its engagement by AATI. AATI also will request that banking institutions, brokerage firms, custodians, trustees, nominees, fiduciaries and other similar record holders forward the solicitation materials to the beneficial owners of common stock held of record by such person, and AATI will, upon request of such record holders, reimburse forwarding charges and out-of-pocket expenses.

The Special Meeting (Page [ • ])

Date, Time and Place. The special meeting will be held on [ • ], 2011, starting at [ • ] a.m. Pacific Daylight Time at the offices of Wilson Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo Alto, California 94304.

Purpose. You will be asked to consider and vote upon (1) the adoption of the merger agreement and the approval of the merger, (2) the approval by non-binding, advisory vote, of certain compensation arrangements for AATI’s named executive officers and directors in connection with the merger, (3) the adjournment of the special meeting to a later date, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the merger agreement and to approve the merger, and (4) such

other business as may properly come before the special meeting by or at the direction of the AATI board of directors or any adjournments or postponements of the special meeting.

Record Date and Quorum. You are entitled to vote at the special meeting if you were the record owner of shares of AATI common stock at the close of business on [ • ], 2011, the record date for the special meeting. Stockholders of record of AATI common stock as of the close of business on the record date will have one vote for each share of AATI common stock owned of record on the record date. As of [ • ], 2011, there were [ • ] shares of AATI common stock issued and outstanding and entitled to vote. A majority of the votes entitled to be cast by holders of the issued and outstanding shares of AATI common stock at the record date constitutes a quorum for the purpose of the special meeting. In the event that a quorum is not present in person or represented by proxy at the special meeting, the meeting may be adjourned or postponed to solicit additional proxies.

Vote Required. The adoption of the merger agreement and the approval of the merger require the affirmative vote of at least a majority of all of the votes entitled to be cast by holders of the shares of AATI common stock that are issued and outstanding as of the record date for the special meeting. Approval of the non-binding, advisory proposal regarding certain merger-related executive compensation arrangements requires the affirmative vote of holders of a majority of the shares of AATI common stock present in person or represented by proxy and entitled to vote thereon. If a quorum is present, approval of any proposal to adjourn the special meeting, if necessary or appropriate, for the purpose of soliciting additional proxies requires the votes cast favoring the action to exceed the votes cast opposing the action.

Share Ownership of Management. As of June 10, 2011, the directors and executive officers of AATI, together with their affiliates, beneficially owned approximately 13% of the shares entitled to vote at the AATI special meeting, including shares issuable upon the exercise of vested options.

The Merger (Page [ • ]) and the Merger Agreement (Page [ • ])

The terms and conditions of the merger are contained in the merger agreement, which is attached to this proxy statement/prospectus as Annex A. AATI and Skyworks encourage you to read the merger agreement carefully, as it is the legal document that governs the merger.

Under the terms of the merger agreement, Merger Sub will merge with and into AATI, and AATI will survive the merger as a wholly owned subsidiary of Skyworks.

The Merger Consideration (Page [ • ])

Upon completion of the merger, each outstanding share of AATI common stock, except for shares of AATI common stock held directly or indirectly by Skyworks, Merger Sub or any wholly owned subsidiary of AATI (which will be cancelled as a result of the merger), and except for shares of AATI common stock held by stockholders exercising dissenter’s rights, will automatically become the right to receive an aggregate of $6.13 per share, payable in the form of 0.08725 of a share of Skyworks common stock (the “stock consideration”) and an adjustable cash amount in the initial calculated amount of $3.68 (the “cash consideration” and, together with the stock consideration, the “merger consideration”), without interest and less applicable withholding taxes. The amount of stock was based on the average last sale price of Skyworks common stock (at the 4 p.m. Eastern Time end of Nasdaq regular trading hours) over the 30 trading days prior to May 26, 2011. At that average price, the stock consideration had a nominal value of $2.45 and the nominal aggregate combined value of the cash consideration and the stock consideration was $6.13. The final cash consideration will depend on the closing value of the stock consideration, calculated on the basis of Skyworks’ average reported last sale price in regular Nasdaq trading during a five-trading-day measurement period preceding the closing of the merger. If the closing value of the stock consideration is less than $2.45, the cash consideration will increase by the amount of the shortfall. If the closing value of the stock consideration is more than $2.45, the cash consideration will decrease by the amount of the excess. And if the closing value of the stock consideration is exactly $2.45, the cash consideration will remain unchanged at $3.68. In each case, the merger consideration will maintain a constant nominal aggregate combined value of $6.13 per share of AATI common stock.

For example:


	•	if Skyworks’ average reported last sale price in the pre-closing measurement period is $26.50, then the closing value of the stock consideration would be $2.31 and the cash amount would increase by $0.14 (the amount of the shortfall between $2.31 and $2.45), from $3.68 to $3.82; and

	•	if Skyworks’ average reported last sale price in the pre-closing measurement period is $30, then the closing value of the stock consideration would be $2.62 and the cash amount would decrease by $0.17 (the amount of the excess of $2.62 over $2.45), from $3.68 to $3.51.

In addition, you should note that if Skyworks’ average last reported sale price during the pre-closing measurement period is less than $21.00, Skyworks has the right to pay the entire $6.13 in cash, and in that event, AATI stockholders would not receive any shares of Skyworks common stock in the merger for their outstanding shares of AATI common stock, and would instead receive $6.13 entirely in cash.

The shares of Skyworks common stock issuable to AATI stockholders in the merger will be registered pursuant to a registration statement on Form S-4 and the shares of Skyworks common stock issuable upon the exercise of AATI stock options that are assumed by Skyworks in the merger and converted in options on Skyworks common stock will be registered pursuant to a registration statement on Form S-8.

You should obtain current stock price quotations for AATI and Skyworks common stock. AATI and Skyworks common stock trade on The Nasdaq Global Select Market under the symbols “AATI” and “SWKS,” respectively.

Treatment of Stock Options, Restricted Stock Units and Employee Stock Purchase Plan (Page [ • ])

If the merger becomes effective:


	•	Each outstanding option to purchase shares of AATI common stock (“AATI option”) will be assumed and converted into an option to purchase shares of Skyworks common stock (a “Skyworks option”), on the same terms and conditions as were applicable immediately prior to the effective time of the merger, but taking into account any acceleration of vesting that applies in connection with the merger. The number of shares of Skyworks common stock subject to each assumed AATI option will be equal to the number of shares of AATI common stock subject to the assumed AATI option immediately prior to the effective time of the merger, multiplied by the option conversion ratio, rounded down, if necessary, to the nearest whole share of Skyworks common stock. The new Skyworks option will have an exercise price per share (rounded up to the nearest whole cent) equal to the exercise price per share of AATI common stock divided by the option conversion ratio. The “option conversion ratio” is defined as $6.13 divided by the average last reported sale price of Skyworks common stock (at the 4 p.m. Eastern Time end of Nasdaq regular trading hours) on the five full trading days ending on the trading day immediately prior to the date on which the effective time of the merger occurs.

	•	Each outstanding award of AATI restricted stock units (“RSUs”) that is to be settled in AATI common stock will be assumed by Skyworks and will be converted into a restricted stock unit to acquire that number of shares of Skyworks common stock equal to the product obtained by multiplying (x) the number of shares of AATI common stock subject to such RSU and (y) the option conversion ratio, rounded down to the nearest whole share of Skyworks common stock. Each assumed RSU will otherwise be subject to the same terms and conditions (including as to vesting) as were applicable to the AATI RSUs immediately prior to the effective time of the merger.

AATI’s Reasons for the Merger (Page [ • ])

In reaching its decision to approve, adopt and declare advisable the merger agreement, the merger and the other transactions contemplated by the merger agreement, the AATI board of directors consulted with AATI’s financial and legal advisors, and with AATI senior management, and considered a number of factors that the board members believed supported their decision.

Recommendation of AATI Board of Directors (Page [ • ])

The AATI board of directors has unanimously determined that the merger is advisable and in the best interests of the stockholders of AATI, and has unanimously authorized and approved the merger agreement, the merger and the other transactions contemplated by the merger agreement, and has unanimously determined that the merger consideration is fair to the stockholders of AATI entitled to receive the merger consideration. The AATI board of directors unanimously recommends that AATI stockholders vote “FOR” the adoption of the merger agreement and the approval of the merger, “FOR” the approval of the non-binding, advisory proposal regarding certain merger-related executive compensation arrangements and “FOR” the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies.

Opinion of AATI’s Financial Advisor (Page [ • ])

In connection with the merger, Needham & Company, LLC (“Needham & Company”), AATI’s financial advisor, delivered a written opinion, dated May 26, 2011, to AATI’s board of directors to the effect that, as of the date of the opinion and based on and subject to various assumptions and limitations described in its opinion, the consideration to be received by the holders of AATI common stock pursuant to the merger agreement was fair, from a financial point of view, to those holders. The full text of the written opinion of Needham & Company, dated May 26, 2011, which describes, among other things, the assumptions made, procedures followed, matters considered and qualifications and limitations on and scope of the review undertaken, is attached as Annex D to this proxy statement/prospectus and is incorporated by reference herein in its entirety. Needham & Company provided its opinion to AATI’s board of directors for the information and assistance of AATI’s board of directors (in its capacity as such) in connection with and for purposes of its evaluation of the merger consideration from a financial point of view. Needham & Company’s opinion does not address any other aspect of the merger and does not constitute a recommendation to any stockholder as to how to vote or act in connection with the proposed merger or any related matter.

Skyworks’ Reasons for the Merger (Page [ • ])

In reaching its decision to approve the merger and its determination that the terms of the merger agreement and the transactions contemplated thereby are advisable, and in the best interests of, Skyworks and its stockholders, the Skyworks board of directors evaluated the merger in consultation with Skyworks’ senior management and advisors, and considered a number of factors that the board members believed supported their decision.

The Stockholder Agreement (Page [ • ])

In connection with the transactions contemplated by the merger agreement, all of AATI’s executive officers and directors have, in their capacity as stockholders of AATI, entered into an agreement with Skyworks (the “stockholder agreement”). Pursuant to the stockholder agreement, among other things, those AATI stockholders irrevocably agreed to vote the shares of AATI common stock owned or subsequently acquired by them (either beneficially or of record) in favor of the merger agreement and the merger. Those stockholders also agreed to vote all of their shares of AATI common stock against any other acquisition proposal or alternative acquisition agreement. As of [ • ], 2011, the record date for the special meeting, the directors and executive officers of AATI beneficially owned in the aggregate approximately [ • ] shares of AATI common stock entitled to vote at the special meeting, representing approximately [ • ]% of the shares of AATI common stock outstanding as of the record date. A copy of the stockholder agreement is attached to this proxy statement/prospectus as Annex B.

The Non-competition Agreement (Page [ • ])

24 months from the date of closing of the merger and subject to certain exceptions, not to engage in any business or activity that is in competition with AATI’s business of developing, designing, manufacturing, licensing, marketing, selling and distributing power management semiconductors and related software. The non-competition agreement is conditioned on the completion of the merger, and if the merger does not occur, the non-competition agreement automatically terminates. A copy of the non-competition agreement is attached to this proxy statement/prospectus as Annex C.

Material U.S. Federal Income Tax Consequences of the Merger (Page [ • ])

The receipt of Skyworks common stock and cash in exchange for AATI common stock in the merger will be a taxable transaction for U.S. federal income tax purposes. A U.S. holder (as defined below) who receives Skyworks common stock and cash in the merger will generally recognize capital gain or loss equal to the difference, if any, between (1) the sum of the fair market value of Skyworks common stock as of the effective time of the merger and the amount of cash received, including any cash received in lieu of fractional shares of Skyworks common stock, received in the merger, and (2) such holder’s adjusted tax basis in its AATI common stock exchanged therefor.

Interests of AATI’s Directors and Executive Officers in the Merger (Page [ • ])

In considering the recommendation of the AATI board of directors to adopt the merger agreement and approve the merger, you should be aware that certain of AATI’s directors and executive officers have interests in the merger that are different from, or in addition to, their interests as AATI stockholders. The AATI board of directors was aware of and considered these interests, among other matters, in reaching its decision to approve, adopt and declare advisable the merger agreement, the merger and the other transactions contemplated by the merger agreement.

All of AATI’s executive officers are parties to change in control agreements with AATI, each of which provides severance and other benefits if the executive’s employment is terminated in connection with a change in control of AATI, including the consummation of the merger. Under certain circumstances, the termination of employment will result in, among other things, acceleration of vesting of some or all unvested equity-related awards granted to AATI officers. Executive officers and directors of AATI have rights to indemnification, advancement of expenses and directors’ and officers’ liability insurance that will survive consummation of the merger.

On May 26, 2011, AATI’s board of directors approved the following grants of restricted stock units to the named executive officers and directors set forth in the table below in connection with their efforts in negotiating the terms of the merger and the merger agreement and in their ongoing efforts that will be needed in order to consummate the merger. These restricted stock units vest over a four-year period with 1/4th of the units vesting on the one year anniversary of the date of grant and 6.25% of the units vesting each quarter thereafter, and are subject to 100% acceleration of vesting in the event of a change of control of AATI, including the consummation of the merger.


		Number of Restricted Stock
Name	Title	Units Granted on May 26, 2011

Richard K. Williams	President, Chief Executive Officer and Chief Technical Officer		60,000
Ashok Chandran	Vice President, Chief Accounting Officer and interim Chief Financial Officer		75,000
Jun-Wei Chen	Vice President of Technology		5,000
Samuel Anderson	Chairman of the Board of Directors		240,000
Jaff Lin	Director		60,000

On May 26, 2011, the Board also approved an additional award of 400,000 restricted stock units to Mr. Richard K. Williams, AATI’s president, chief executive officer and chief technical officer, as consideration

for entering into the non-competition agreement with Skyworks as a condition to the merger. Such restricted stock units vest, if at all, monthly over a 2-year period commencing with the date of the closing of the merger.

See “The Merger Agreement — Conditions to the Merger.” The definition of a “material adverse effect” is described in the section of this proxy statement/prospectus entitled “The Merger Agreement — Material Adverse Effect.”

No Solicitation (Page [ • ])

The merger agreement prohibits AATI from directly or indirectly soliciting or negotiating acquisition proposals (as that term is described in the section of this proxy statement/prospectus entitled “The Merger Agreement — No Solicitation”). However, under certain circumstances the merger agreement permits AATI to respond to certain written acquisition proposals AATI receives and, subject to payment of a termination fee, terminate the merger agreement to enter into a definitive agreement with respect to a superior proposal (as that term is described in the section of this proxy statement/prospectus entitled “The Merger Agreement — No Solicitation”).

Termination of the Merger Agreement (Page [ • ]) and Transaction Fees and Expenses; Termination Fee (Page [ • ])

Skyworks and AATI may terminate the merger agreement at any time upon mutual written consent of the parties. Other circumstances under which Skyworks or AATI may terminate the merger agreement are described in the section of this proxy statement/prospectus entitled “The Merger Agreement — Termination of the Merger Agreement.”

AATI is required to pay Skyworks a termination fee of $8,500,000 if the merger agreement is terminated following a change by the AATI board of directors of its recommendation in favor of the merger or in connection with AATI’s entry into a definitive agreement with respect to a superior proposal (as such term is described in the section of this proxy statement/prospectus entitled “The Merger Agreement — No Solicitation”) from another party or under certain other circumstances, all as described in the section of this proxy statement/prospectus entitled “The Merger Agreement — Transaction Fees and Expenses; Termination Fee.”

AATI is required to pay Skyworks’ and Merger Sub’s expenses incurred in connection with the merger, in an amount not to exceed $500,000, if the merger agreement is terminated under certain other circumstances. See the section of this proxy statement/prospectus entitled “The Merger Agreement — Transaction Fees and Expenses; Termination Fee.”

In no event will AATI be required to pay both the termination fee and Skyworks’ and Merger Sub’s expenses.

Regulatory Approvals (Page [ • ])

AATI and Skyworks cannot complete the merger unless they receive approvals or waivers of approval from applicable regulatory authorities. Skyworks has preliminarily determined that the transactions contemplated by the merger agreement are not subject to a waiting period or filings under the HSR Act, but do require a filing and are subject to review in the Republic of Korea. AATI and Skyworks have agreed to use their respective reasonable best efforts to take, or cause to be taken, all actions, and to do, or cause to be done, and to assist and cooperate with each other in doing, all things necessary, proper or advisable to obtain all approvals, consents, registrations, permits, authorizations and other confirmations from any governmental authority or third party necessary, proper or advisable to consummate the merger.

For a discussion of the parties’ obligations to use certain efforts to obtain regulatory approvals for the merger, see the section of this proxy statement/prospectus entitled “The Merger Agreement — Efforts to Consummate the Merger; Regulatory Matters.”

Listing of Skyworks Common Stock and Delisting of AATI Common Stock (page [ • ])

It is a condition to the merger that Skyworks file a notification of listing with Nasdaq for the shares of common stock to be issued by Skyworks pursuant to the merger agreement. The shares of common stock to be issued by Skyworks pursuant to the merger agreement will trade under the symbol “SWKS” on the same terms as the Skyworks common stock currently trading under that symbol. Shares of AATI common stock are currently traded on The Nasdaq Global Select Market under the symbol “AATI.” If the merger is completed, AATI common stock will no longer be listed on The Nasdaq Global Select Market and will be deregistered under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and AATI will no longer file periodic reports with the SEC.

AATI Stockholders’ Rights of Appraisal (page [ • ])

Under Section 262 of the Delaware General Corporation Law, as amended (the “DGCL”), holders of AATI common stock may have the right to obtain an appraisal of the value of their shares of AATI common stock in connection with the merger. To perfect appraisal rights, an AATI stockholder must not vote for the adoption of the merger agreement and must strictly comply with all of the procedures required under Delaware law, including submitting a written demand for appraisal to AATI prior to the special meeting. Failure to strictly comply with Section 262 of the DGCL by an AATI stockholder may result in termination or waiver of that stockholder’s appraisal rights. Because of the complexity of Delaware law relating to appraisal rights, if any AATI stockholder is considering exercising his, her or its appraisal rights, Skyworks and AATI encourage such AATI stockholder to seek the advice of his, her or its own legal counsel and financial advisor. A summary of the requirements under Delaware law to exercise appraisal rights is included in this proxy statement/prospectus under the heading “The Merger — AATI Stockholders’ Rights of Appraisal” on page [ • ] and the text of Section 262 of the DGCL as in effect with respect to this transaction is included as Annex E to this proxy statement/prospectus.

Risk Factors (Page [ • ])

In evaluating the merger and the merger agreement and deciding how to vote at the special meeting, you should read carefully this proxy statement/prospectus, and especially consider the factors discussed in the section entitled “Risk Factors” beginning on page [ • ], in addition to the risks described in Item 1A of Skyworks’ Form 10-Q for the fiscal quarter ended April 1, 2011, filed with the SEC on May 11, 2011, in

Item 1A of Skyworks’ Form 10-Q for the fiscal quarter ended December 31, 2010, filed with the SEC on February 8, 2011, in Item 1A of Skyworks’ Form 10-K for the fiscal year ended October 1, 2010, filed with the SEC on November 29, 2010 and amended by Amendment No. 1 thereto filed with the SEC on January 31, 2011, in Item 1A of AATI’s Form 10-Q for the quarter ended March 31, 2011, filed with the SEC on May 3, 2011, and in Item 1A of AATI’s Form 10-K for the year ended December 31, 2010, filed with the SEC on February 25, 2011, as amended by Amendment No. 1 thereto filed with the SEC on May 2, 2011, and the risks described in the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the heading “Forward-Looking Statements.”

Delisting and Deregistration of AATI Common Stock (Page [ • ])

If the merger is completed, shares of AATI common stock will no longer be listed or traded on Nasdaq and will be deregistered under the Exchange Act.

Litigation Related to the Merger (Page [ • ])

Beginning on June 6, 2011, two putative class action lawsuits were filed purportedly on behalf of AATI’s stockholders in Santa Clara Superior Court, California, captioned Bushansky v. Advanced Analogic Technologies Inc., et al., No. 111CV202403 (the “Bushansky Complaint”), and Venette v. Advanced Analogic Technologies Inc., et al., No. 111CV202501 (the “Venette Complaint”) (together, the “Complaints”). The plaintiffs in these actions generally allege that (1) the members of AATI’s board of directors breached their fiduciary duties to AATI and its stockholders by failing to take steps to maximize stockholder value and by authorizing the sale of AATI to Skyworks in what plaintiffs allege to have been an inadequate process resulting in inadequate consideration to AATI stockholders, and (2) AATI, the members of AATI’s board of directors, Skyworks and Merger Sub aided and abetted the other defendants’ alleged breach of fiduciary duties. These lawsuits generally seek, among other things, to enjoin the merger, to recover the costs of the actions, including attorneys’ fees, and to obtain other related relief. The Bushansky Complaint also seeks to recover compensatory damages.

AATI, AATI’s board of directors and Skyworks believe that the claims in both of these actions are without merit and intend to defend against such claims vigorously.

Dividend Policy (Page [ • ])

Skyworks and AATI stockholders have historically not received dividends. The payment of dividends by Skyworks after the merger will be subject to the determination of the Skyworks board of directors. Decisions by the Skyworks board of directors regarding whether or not to pay dividends on Skyworks common stock and the amount of any dividends will be based on compliance with the DGCL and agreements and other factors that the Skyworks board of directors considers important. Skyworks has not paid a dividend on its common stock since its incorporation. While Skyworks anticipates that if the merger were consummated it would continue not to pay dividends, Skyworks can make no assurances that this will be the case in the future.

Comparison of Rights of AATI and Skyworks Stockholders (Page [ • ])

As a result of the merger, the holders of AATI common stock will become holders of Skyworks common stock and their rights will be governed by the DGCL and by Skyworks’ certificate of incorporation and bylaws. Following the merger, AATI stockholders may have different rights as stockholders of Skyworks than as stockholders of AATI. For a summary of the material differences between the rights of AATI stockholders and Skyworks stockholders, see “Comparison of Rights of AATI and Skyworks Stockholders” beginning on page [ • ].

RISK FACTORS

In addition to the risks described in Item 1A of Skyworks’ Form 10-Q for the fiscal quarter ended April 1, 2011, filed with the SEC on May 11, 2011, in Item 1A of Skyworks’ Form 10-Q for the fiscal quarter ended December 31, 2010, filed with the SEC on February 8, 2011, in Item 1A of Skyworks’ Form 10-K for the fiscal year ended October 1, 2010, filed with the SEC on November 29, 2010 and amended by Amendment No. 1 thereto filed with the SEC on January 31, 2011, in Item 1A of AATI’s Form 10-Q for the quarter ended March 31, 2011, filed with the SEC on May 3, 2011, and in Item 1A of AATI’s Form 10-K for the year ended December 31, 2010, filed with the SEC on February 25, 2011, as amended by Amendment No. 1 thereto filed with the SEC on May 2, 2011, and the risks described in the other information contained in or incorporated by reference into this proxy statement/prospectus, including the matters addressed under the heading “Forward-Looking Statements,” you should carefully consider the following risk factors in deciding how to vote:

The stock prices of Skyworks and AATI may be adversely affected if the merger is not completed.

Completion of the merger is subject to certain closing conditions, including, among others, obtaining requisite regulatory approvals and the approval of AATI’s stockholders. Skyworks and AATI may be unable to obtain such approvals on a timely basis or at all. Other closing conditions may not be satisfied. If the merger is not completed, the prices of Skyworks common stock and AATI common stock may decline to the extent that the current market prices of Skyworks common stock and AATI common stock reflect a market assumption that the merger will be completed and to the extent that the businesses of Skyworks and AATI are adversely affected if the merger is not completed.

AATI will be subject to business uncertainties while the merger is pending.

Uncertainty about the effect of the merger on employees, customers, suppliers and other business partners may have an adverse effect on AATI and consequently on Skyworks following the merger. These uncertainties could cause customers, suppliers, business partners and others that deal with AATI to defer entering into contracts with AATI or making other decisions concerning AATI or seek to change existing business relationships with AATI. In addition, except as expressly permitted by the merger agreement or as required by applicable law, subject to certain exceptions, until the effective time of the merger, the merger agreement restricts AATI’s ability to take certain action and engage in certain transactions, as described under “The Merger Agreement — Covenants Regarding Conduct of Business by AATI Prior to the Merger.”

Any delay in completing the merger may substantially reduce the benefits that Skyworks and AATI expect to obtain from the merger.

In addition to the expiration or termination of the applicable waiting period under the HSR Act, the merger is subject to a number of other conditions beyond the control of Skyworks and AATI that may prevent, delay or otherwise materially adversely affect its completion. See “The Merger Agreement — Conditions to the Merger.” There can be no assurance that all conditions will be satisfied, and Skyworks and AATI cannot predict whether or when the conditions required to complete the merger will be satisfied. The requirements for obtaining required approvals could delay the effective time of the merger for a significant period of time or prevent it from occurring at all. Moreover, each of Skyworks and AATI may terminate the merger agreement if the merger is not consummated by December 31, 2011. See “The Merger Agreement — Termination of the Merger Agreement.” Any delay in completing the merger may materially adversely affect the synergies and other benefits that Skyworks and AATI expect to achieve if they complete merger and the integration of the companies’ respective businesses within the expected time frame.

The businesses of Skyworks and AATI may be adversely affected if the merger is not completed.

If the merger is not completed, the respective ongoing businesses of Skyworks and AATI may be adversely affected and Skyworks and AATI will be subject to several risks and consequences, including the following:


	•	the merger agreement requires AATI, under certain circumstances, to pay Skyworks a termination fee of $8.5 million, and, under certain other circumstances, to pay up to $500,000 of Skyworks’ and Merger Sub’s expenses incurred in connection with the merger;

	•	Skyworks and AATI will have to pay certain costs incurred by each of them relating to the merger, whether or not the merger is completed;

	•	under the merger agreement, AATI is subject to certain restrictions on the conduct of its business prior to completing the merger which may adversely affect its ability to execute certain of its business strategies; and

	•	matters relating to the merger may require substantial commitments of time and resources by Skyworks and AATI management, which could otherwise have been devoted to other opportunities that may have been beneficial to Skyworks and AATI as independent companies, as the case may be.

In addition, there may be uncertainty surrounding the future direction of the businesses and strategy of Skyworks or AATI on a standalone basis, and Skyworks or AATI may experience negative reactions from the financial markets and from their respective employees, customers, suppliers and other business partners. Skyworks and AATI could be subject to litigation related to any failure to complete the merger, or to enforcement proceedings commenced against Skyworks or AATI to perform their respective obligations under the merger agreement. If the merger is not completed, Skyworks and AATI cannot assure their respective stockholders that the risks described above will not materialize and will not materially adversely affect the business, financial condition, results of operations and stock prices of Skyworks or AATI. Moreover, as AATI and Skyworks dedicate resources and attention to the merger and subsequent integration, each company’s competitors may exploit the opportunity to improve the position of their businesses and gain market share.

AATI has limited rights to terminate the merger agreement and may not terminate the merger agreement to enter into a definitive agreement with respect to a superior proposal to acquire AATI except in connection with a change in the AATI board’s recommendation in favor of the merger made before AATI stockholders have adopted the merger agreement and approved the merger. If AATI exercises its rights to terminate the merger agreement, AATI may in certain circumstances be required to pay a termination fee to Skyworks.

In the merger agreement, AATI has agreed not to directly or indirectly solicit, initiate, knowingly encourage or take any other action to facilitate any inquiries or the making of any proposal or offer that constitutes, or could reasonably be expected to lead to, a proposal to acquire 10% or more of AATI or its assets, whether by merger, consolidation, dissolution, sale of assets, tender offer, recapitalization, share exchange, other business combination, or issuance of equity securities, or in any other manner. In addition, AATI has agreed not to enter into, continue or otherwise participate in any discussions or negotiations regarding such an acquisition proposal, or to furnish to any person any information with respect to such an acquisition proposal, or to assist or participate in any effort or attempt by any person with respect to such an acquisition proposal, or otherwise to cooperate in any way with, such an acquisition proposal. AATI has also agreed to cause its subsidiaries and its and their directors, officers and employees not to take any of the actions described above, and to use its reasonable best efforts to cause its investment bankers, attorneys, accountants and other advisors and representatives not to take any of these actions. AATI has also agreed not to enter into any acquisition agreement, merger agreement or similar agreement (including any letter of intent, memorandum of understanding, or agreement in principle) constituting or relating to an acquisition proposal.

If AATI receives an unsolicited superior proposal to acquire AATI, and if certain other conditions and requirements are met, the AATI board of directors may terminate the merger agreement to concurrently enter into a definitive agreement to effect an unsolicited superior proposal. But in such a case, AATI is required to

pay a termination fee of $8.5 million to Skyworks. See “The Merger Agreement — No Solicitation,” “The Merger Agreement — Termination of the Merger Agreement” and “The Merger Agreement — Transaction Fees and Expenses; Termination Fee.”

In addition, if AATI stockholders have not yet adopted the merger agreement, AATI may take certain otherwise prohibited actions in response to an unsolicited proposal from a third party that constitutes (or that the AATI board of directors determines in good faith, after consultation with outside legal counsel and its independent financial advisors, is reasonable likely to lead to) a superior proposal, to the extent that the fiduciary obligations of the AATI board of directors require (as determined in good faith by AATI’s board of directors after consulting with outside counsel). But the proposal cannot be the result of a breach by AATI of the “no-shop” restrictions described above.

To qualify as a superior proposal, the proposal must be an unsolicited, bona fide written proposal from a third party to acquire more than 50% of the equity securities or assets of AATI and its subsidiaries, and AATI’s board of directors must determine in its good faith judgment, after consultation with a nationally recognized independent financial advisor, that the terms of the proposal are more favorable to AATI common stockholders than the transactions contemplated by the merger agreement, taking into account all the terms and conditions of the proposal and the merger agreement (including any proposal by Skyworks to amend the terms of the merger agreement). AATI’s board of directors must also determine that the terms of the other proposal are reasonably capable of being completed on the terms proposed, taking into account all financial, regulatory, legal and other aspects of such proposal. No proposal will qualify as a superior proposal if any financing required to consummate the proposal is not committed.

Subject to the exception described below, the merger agreement prohibits AATI’s board of directors from withholding, withdrawing, amending, changing, qualifying or modifying its recommendation in favor of the merger in a manner adverse to Skyworks, or publicly proposing to withhold, withdraw, amend, change, qualify or modify its recommendation in favor of the merger in a manner adverse to Skyworks. With a limited exception, the merger agreement also prohibits AATI’s board of directors from approving, adopting or recommending to AATI stockholders any other acquisition proposal, or publicly (or in a manner designed to become public) proposing to approve, adopt or recommend any other acquisition proposal to AATI stockholders, or making any public statement in connection with a tender offer or exchange offer for AATI shares (other than a “stop, look and listen” communication by the AATI board pursuant to federal securities law), unless the statement includes a reaffirmation of the AATI board’s recommendation in favor of the merger.

Notwithstanding these limitations, the merger agreement allows AATI’s board of directors to change its recommendation in favor of the merger and support an alternative acquisition proposal if the following conditions apply:


	•	AATI’s board of directors must have received an alternative acquisition proposal and it must have determined in good faith (after consultation with its financial advisors and outside legal counsel) that the other proposal constitutes a superior proposal;

	•	the failure to take such action would reasonably be expected to be a breach of its fiduciary duties;

	•	AATI stockholders must not have adopted the merger agreement and approved the merger;

	•	AATI must not have violated, in any material respect, any of the terms of the “no-shop” restrictions described above in connection with such acquisition proposal;

	•	AATI must have given Skyworks at least three business days’ prior written notice of its intention to take such action (and the notice must have included the terms and conditions of the other proposal);

	•	no later than the time of such notice, AATI must have provided Skyworks with a copy of the relevant proposed transaction agreement and other material documents with the other party;

	•	if requested by Skyworks, AATI must have negotiated in good faith with Skyworks during the three business day notice period to enable Skyworks to propose changes to the terms of the merger agreement that would cause the other proposal to no longer constitute a superior proposal;


	•	AATI’s board of directors must have considered in good faith (after consultation with its financial advisors and outside legal counsel) any changes to the merger agreement proposed by Skyworks in a written offer capable of acceptance and must have determined that the other proposal would continue to constitute a superior proposal even if the changes proposed by Skyworks were made to the merger agreement; and

	•	in the event of any material change to the financial or other material terms of the other proposal, AATI must have delivered to Skyworks an additional notice and copies of the relevant proposed transaction agreement and other material documents, with a new three business day notice period.

If these conditions are satisfied, the merger agreement also allows AATI to terminate the merger agreement and enter into an agreement with another party after paying a termination fee of $8.5 million to Skyworks.

These provisions might discourage a potential competing acquirer that might have an interest in acquiring all or a significant part of AATI from considering or proposing an acquisition even if it were prepared to pay consideration with a higher value than the consideration offered in connection with the merger, or might result in a potential competing acquirer proposing to pay a less valuable per share consideration to acquire AATI than it might otherwise have proposed to pay.

Some of AATI’s officers and directors have interests in the merger that are different from, and in addition to, your interests and will directly benefit from the merger.

Some of the directors of AATI who recommend that you vote in favor of the proposals to be considered at the special meeting of AATI stockholders, and the officers of AATI who provided information to AATI’s board of directors relating to the merger and the other transactions contemplated by the merger agreement, have rights to acceleration of the vesting of their equity-based awards, to ongoing indemnification and insurance, and, in the case of the officers of AATI, to severance and other benefits in the case of termination of employment or non-renewal of employment agreements upon the consummation of the merger, that provide them with interests in the transaction that may differ from, or be in addition to, those of AATI’s stockholders. The receipt of compensation or other benefits in connection with the transaction might result in these directors and officers being more likely to support and vote to adopt the merger agreement and approve the merger than if they did not have these interests. AATI stockholders should consider whether their interests and benefits might have influenced these directors and officers to support or recommend adoption of the merger agreement and approval of the merger. See the section entitled “The Merger — Interests of AATI’s Directors and Executive Officers in the Merger” for a further description of these interests.

Uncertainties associated with the merger may cause a loss of employees and may otherwise affect the future business and operations of Skyworks.

Skyworks’ success after the merger will depend in part upon its ability to retain key employees of Skyworks and AATI. Prior to the merger, employees of Skyworks or AATI may experience uncertainty about their roles with Skyworks following the merger. Employees of AATI who are retained by Skyworks following the merger may also experience similar uncertainty after the completion of the merger. This may adversely affect the ability of each of Skyworks and AATI to retain key management, sales, technical and other personnel. Key employees of AATI and Skyworks may depart because of issues relating to the uncertainty and difficulty of integration or a desire not to remain with Skyworks following the merger. As a result, Skyworks may not be able to attract or retain key employees of Skyworks and AATI following the merger to the same extent that Skyworks and AATI have been able to attract or retain their own employees in the past, which could have a negative impact on the business of Skyworks following the merger. If key employees depart, the integration of the companies may be more difficult, and Skyworks’ business following the merger could be materially harmed.

Combining the businesses of Skyworks and AATI may be more difficult, costly or time-consuming than expected, which may adversely affect Skyworks’ results of operations and adversely affect the value of Skyworks common stock following the merger.

Skyworks and AATI have entered into the merger agreement because they believe that the merger will be beneficial to the respective companies and their respective stockholders. The success of the merger will depend, in part, on Skyworks’ ability to realize the anticipated benefits from combining the businesses of Skyworks and AATI. To realize these anticipated benefits, Skyworks must successfully combine the businesses of Skyworks and AATI in an efficient and effective manner. If Skyworks is not able to achieve these objectives within the anticipated time frame, or at all, the anticipated benefits and cost savings of the merger may not be realized fully, or at all, or may take longer to realize than expected, and the value of Skyworks common stock may be adversely affected.

Skyworks and AATI have operated and, until the completion of the merger, will continue to operate, independently. It is possible that the integration process could result in the loss of key employees, the disruption of each company’s ongoing business or inconsistencies in standards, controls, procedures and policies that adversely affect Skyworks’ or AATI’s ability to maintain relationships with customers, employees, suppliers and other business partners following the merger or to achieve the anticipated benefits of the merger. Specifically, issues that must be addressed in integrating the operations of AATI into Skyworks’ operations to realize the anticipated benefits of the merger include, among other things:


	•	integrating and optimizing the utilization of the properties, equipment, suppliers, distribution channels, manufacturing, marketing, promotion and sales activities and information technologies of Skyworks and AATI;

	•	consolidating corporate and administrative infrastructures of Skyworks and AATI;

	•	coordinating geographically dispersed organizations of Skyworks and AATI;

	•	retaining existing customers and attracting new customers of Skyworks and AATI; and

	•	conforming standards, controls, procedures and policies, business cultures and compensation structures between the companies.

Integration efforts between the two companies will also divert management attention and resources. An inability to realize the full extent of the anticipated benefits of the merger, as well as any delays encountered in the integration process, could have an adverse effect upon Skyworks’ results of operations, which may affect adversely the value of Skyworks common stock after the completion of the merger.

In addition, the actual integration may result in additional and unforeseen expenses, and the anticipated benefits of the integration plan may not be realized. Actual synergies, if achieved at all, may be lower than what Skyworks expects and may take longer to achieve than anticipated. If Skyworks is not able to address these challenges adequately, Skyworks may be unable to successfully integrate AATI’s operations into its own operations or to realize the anticipated benefits of the integration of the two companies.

Because the market value of the Skyworks common stock that AATI stockholders will receive in the merger may fluctuate, AATI stockholders cannot be sure of the exact amount of cash they will receive or the exact market value of the Skyworks common stock they will receive upon completion of the merger.

Upon completion of the merger, each outstanding share of AATI common stock (except for shares of AATI common stock held directly or indirectly by Skyworks, Merger Sub or any wholly owned subsidiary of Skyworks or AATI, and except for shares of AATI common stock held by stockholders exercising dissenter’s rights) will automatically become the right to receive an aggregate of $6.13 per share, payable in the form of 0.08725 of a share of Skyworks common stock (the “stock consideration”) and an adjustable cash amount in the initial calculated amount of $3.68 (the “cash consideration” and, together with the stock consideration, the “merger consideration”), without interest and less applicable withholding taxes. The amount of stock was based on the average last sale price of Skyworks common stock (at the 4 p.m. Eastern Time end of Nasdaq regular trading hours) over the 30-trading days prior to May 26, 2011. At that average price, the stock

consideration had a nominal value of $2.45 and the nominal aggregate combined value of the cash consideration and the stock consideration was $6.13. The final cash consideration will depend on the closing value of the stock consideration, calculated on the basis of Skyworks’ average reported last sale price in regular Nasdaq trading during a five-trading-day measurement period preceding the closing of the merger. If the closing value of the stock consideration is less than $2.45, the cash consideration will increase by the amount of the shortfall. If the closing value of the stock consideration is more than $2.45, the cash consideration will decrease by the amount of the excess. And if the closing value of the stock consideration is exactly $2.45, the cash consideration will remain unchanged at $3.68. In each case, the merger consideration will maintain a constant nominal aggregate combined value of $6.13 per share of AATI common stock.

For example:


	•	if Skyworks’ average reported last sale price in the pre-closing measurement period is $26.50, then the closing value of the stock consideration would be $2.31 and the cash amount would increase by $0.14 (the amount of the shortfall between $2.31 and $2.45), from $3.68 to $3.82; and

	•	if Skyworks’ average reported last sale price in the pre-closing measurement period is $30, then the closing value of the stock consideration would be $2.62 and the cash amount would decrease by $0.17 (the amount of the excess of $2.62 over $2.45), from $3.68 to $3.51.

As a result of these adjustments and provisions, AATI stockholders will not capture or suffer the full economic consequences (whether positive or negative) that may result from changes in the trading price of Skyworks common stock between May 26, 2011, the date of the merger agreement, and their receipt of Skyworks common stock in the merger. In addition, the exact market value of the shares of Skyworks common stock that AATI stockholders receive in the merger will depend on the market value of shares of Skyworks common stock at the time they actually receive those shares and could vary significantly from the market value of shares of Skyworks common stock on the date the merger agreement was executed, the date of this proxy statement/prospectus, or the date of the special meeting, and could also vary significantly from any of the average prices used in the calculations of the stock consideration and the cash consideration.

Stock price changes may result from a variety of factors, including general market and economic conditions, changes in Skyworks’ and AATI’s businesses, operations, financial results and prospects, regulatory considerations and related developments. Many of these factors are beyond either party’s control. As a result, the value represented by the stock consideration portion of the merger consideration may also vary. For example, based on the range of closing prices of Skyworks common stock during the period from May 25, 2011, the last complete trading day before the day Skyworks and AATI announced the execution of the merger agreement, through [ • ], 2011, the latest practicable date before the date of this proxy statement/prospectus, the stock consideration portion of the merger consideration represented a value ranging from a high of approximately $[ • ] to a low of approximately $[ • ] for each share of AATI common stock. Because the merger is not expected to be consummated until the third quarter of calendar 2011 and could be further delayed, at the time of the special meeting you will not know the market value of Skyworks common stock that you will receive upon completion of the merger, and the market value of Skyworks common stock will continue to fluctuate following the merger. Skyworks and AATI recommend that you obtain current market quotations for Skyworks common stock and AATI common stock before voting at the special meeting. See the section entitled “Comparative Per Share Market Price and Dividend Information.”

The market price of Skyworks common stock after the merger may be affected by factors different from those affecting the shares of Skyworks and AATI common stock prior to the merger.

The businesses of Skyworks and AATI differ in many respects, including product offerings and relationships with customers and suppliers, and, accordingly, the results of operations of Skyworks following

the merger and the market price of shares of Skyworks common stock after the merger may be affected by factors different from those currently affecting the independent results of operations of AATI. For a discussion of the businesses of Skyworks and AATI and of certain factors to consider in connection with their respective businesses, see the documents incorporated by reference into this proxy statement/prospectus and referred to under “Where You Can Find More Information.” See the section entitled “Comparative Per Share Market Price and Dividend Information” for additional information on the historical market value of shares of Skyworks common stock and AATI common stock.

Skyworks and AATI will incur significant costs in connection with the merger.

Skyworks expects to incur approximately $[ • ] million of out-of-pocket costs associated with the merger, consisting primarily of financial, legal and accounting fees and expenses. Similarly, AATI expects to incur approximately $[ • ] million of out-of-pocket costs associated with the merger, consisting primarily of financial, legal and accounting fees and expenses. Skyworks also expects to incur non-recurring costs associated with combining the operations of the two companies. Most of these costs will be comprised of facilities and systems consolidation costs and employment-related costs. Skyworks will also incur fees and costs related to formulating integration plans. Additional unanticipated costs may be incurred in the integration of the two companies’ businesses. Although Skyworks expects that the elimination of duplicative costs, as well as the realization of other efficiencies related to the integration of the businesses, should allow Skyworks to offset incremental transaction and merger-related costs over time, this net benefit may not be achieved in the near term, or at all.

The merger may not be accretive and may cause dilution to Skyworks’ earnings per share, which may negatively affect the market price of Skyworks common stock.

Skyworks currently expects the acquisition of AATI to be immediately accretive to its earnings per share on a non-GAAP earnings basis (which, as presented by Skyworks, excludes stock compensation expense, restructuring-related charges, acquisition-related expenses, amortization of discount on convertible debt, and certain deferred executive compensation, as well as certain items related to the retirement of convertible debt, and certain tax items, which may not occur in all periods for which financial information is presented). This expectation is based on preliminary estimates, which may change materially. Skyworks may also encounter additional transaction-related costs or other factors such as the failure to realize all of the benefits anticipated in the merger. All of these factors could cause dilution to Skyworks’ adjusted non-GAAP earnings per share or decrease or delay the expected accretive effect of the merger and cause a decrease in the market price of Skyworks common stock.

Skyworks and AATI must obtain regulatory approvals to complete the merger, which, if delayed, not granted or granted with unacceptable conditions, may jeopardize or postpone the completion of the merger, result in additional expenditures of money and resources, reduce the anticipated benefits of the merger or adversely affect the stock prices of Skyworks and AATI.

Completion of the merger is subject to obtaining requisite regulatory approvals. Skyworks and AATI may be unable to obtain such approvals on a timely basis or at all, or such approvals may be obtained only with unacceptable conditions or costs. This may jeopardize or postpone the completion of the merger, result in additional expenditures of money and resources, reduce the benefits of the merger that Skyworks and AATI currently anticipate, or adversely affect the stock prices of Skyworks and AATI.

After the merger, AATI stockholders will exercise less influence over the management and policies of Skyworks than they do over AATI.

AATI stockholders currently have the right to vote in the election of the board of directors of AATI and on other matters affecting AATI. If the merger is completed, each AATI stockholder that receives shares of Skyworks common stock will become a stockholder of Skyworks with a percentage ownership of Skyworks that is much smaller than the stockholder’s current percentage ownership of AATI. For example, an AATI stockholder owning 10,000 shares of AATI common stock as of the date of this proxy statement/prospectus

would have a percentage ownership of AATI immediately prior to the effective time of the merger of approximately .0201%, assuming that all outstanding vested options with an exercise price less than $6.13 are exercised, and that 49,860,830 shares of AATI common stock are outstanding immediately prior to the effective time of the merger. Such an AATI stockholder would receive 872 shares of Skyworks common stock in the merger, representing a percentage ownership of Skyworks of approximately 0.0005% immediately following the effective time of the merger, assuming that 184,108,347 shares of Skyworks common stock are outstanding immediately prior to the effective time of the merger and that 4,350,358 shares of Skyworks common stock are issued as stock consideration in the merger. It is expected that the former stockholders of AATI as a group will own approximately 3% or less of the outstanding shares of Skyworks, in the aggregate, immediately after the effective time of the merger, based upon the assumptions described above. No assurance can be given that the outstanding share numbers and percentages referenced above will be the actual outstanding share numbers and percentages as of the specified dates in the future. Such numbers are provided only for purposes of illustration. As illustrated above, following the effective time of the merger, AATI stockholders will have less influence over the management and policies of Skyworks than they now have over the management and policies of AATI.

The shares of Skyworks common stock that AATI stockholders will receive as a result of the merger will have different rights than their shares of AATI common stock.

Upon completion of the merger, AATI stockholders will become Skyworks stockholders, and their rights as stockholders will be governed by Skyworks’ amended and restated certificate of incorporation, Skyworks’ amended and restated bylaws, and Delaware law. Certain of the rights associated with AATI common stock are different from the rights associated with Skyworks common stock. See the section entitled “Comparison of Rights of AATI and Skyworks Stockholders” for a discussion of the different rights associated with Skyworks common stock.

Lawsuits are pending against AATI, the members of AATI’s board of directors, and Skyworks challenging the merger, and an adverse judgment or ruling in any lawsuit challenging the merger may prevent the merger from being completed within the expected timeframe, or at all.

AATI, certain of its directors, Skyworks and Merger Sub are parties to several lawsuits filed by third parties seeking equitable relief, including an injunction against the merger, and costs and expenses of the litigation, including attorneys’ fees, in connection with the merger agreement. The defendants consider the complaints to be without merit and intend to vigorously defend against them. See “The Merger — Litigation Related to the Merger.”

One of the conditions to the closing of the merger is the absence of any law, temporary restraining order, injunction, judgment, order or decree issued by any governmental entity that prohibits or makes illegal the consummation of the merger. As such, if the plaintiffs are successful in obtaining an injunction prohibiting AATI or Skyworks from consummating the merger on the agreed-upon terms, then such injunction may prevent the merger from being completed within the expected timeframe, or at all.

The financial results of the combined company may materially differ from the pro forma financial information and financial forecasts presented in this proxy statement/prospectus.

The pro forma financial information and financial forecasts presented in this proxy statement/prospectus reflect the estimates, assumptions and judgments made by management of Skyworks and AATI. These estimates, assumptions and judgments have affected the reported amounts of assets and liabilities as of the dates presented as well as revenue and expenses reported for the periods presented. The resolution of differences between the two companies’ accounting policies and methods, including estimates, assumptions and judgments, may result in materially different financial information than is presented in the pro forma financial statements and financial forecasts.

Following the merger, Skyworks and AATI will continue to have substantial revenue concentration in the handset and consumer markets which are subject to volatile changes in business conditions and in industry standards.

Both Skyworks and AATI have and will continue to have significant business in the handset and consumer market place following the merger. These markets are known for business volatility, rapidly evolving standards, aggressive competition, and strong seasonality. While both companies are executing diversification strategies to reduce their dependence on these markets on a percentage basis, there is no certainty if or when such diversification efforts will be successful.

Skyworks has recently completed another corporate acquisition, and the concurrent integration of two acquired businesses may affect Skyworks’ ability to integrate one or both of the two acquired companies successfully or extend the time required to complete their integration.

On June 10, 2011, Skyworks completed the acquisition of SiGe Semiconductor, Inc., a supplier of radio frequency (RF) front-end solutions that facilitate wireless multimedia across a wide range of applications. The integration of SiGe may not be complete when the merger closes. This would mean that Skyworks’ management would be integrating two corporate acquisitions simultaneously, in different businesses and in different locations. This might strain the capacities of Skyworks’ management, and might affect the success of integration efforts and result in longer integration time for the integration of AATI, SiGe or both companies. It might also result in distraction of management attention from other parts of Skyworks’ business. The completion of two acquisitions in a short period of time, one for cash (SiGe) and the other for a mix of cash and stock (AATI) will also reduce Skyworks’ cash on hand and may, at least temporarily and in the near term, reduce Skyworks’ ability to pursue other corporate acquisitions and strategic opportunities.

Skyworks may pursue other strategic transactions in the future, which could be difficult to implement, disrupt its business or change its business profile significantly.

Skyworks will continue to consider potential strategic transactions, which could involve acquisitions or dispositions of businesses or assets. Any future strategic transaction could involve numerous risks, including:


	•	potential disruption of Skyworks’ ongoing business and distraction of management;

	•	difficulty integrating acquired businesses or segregating assets to be disposed of;

	•	exposure to unknown, contingent or other liabilities, including litigation arising in connection with the acquisition or disposition against any businesses Skyworks may acquire; and

	•	changing Skyworks’ business profile in ways that could have unintended consequences.

If Skyworks enters into significant strategic transactions in the future, related accounting charges may adversely affect its financial condition and results of operations, particularly in the case of any acquisitions. In addition, the financing of any significant acquisition may result in changes in its capital structure, including the incurrence of additional indebtedness and the dilution of its existing stockholders’ ownership.

COMPARATIVE PER SHARE DATA

The following table shows unaudited per share data regarding net income (loss) from operations, book value for Skyworks and AATI on a historical and pro forma combined basis. Neither Skyworks nor AATI have declared any dividends (cash or otherwise) during the periods presented. The pro forma book value information was computed as if the merger had been completed on April 1, 2011. The pro forma net income from operations information was computed as if the merger had been completed on October 3, 2009. The AATI pro forma equivalent information was calculated by multiplying the corresponding pro forma combined data by an exchange ratio of 0.08725 (as per the merger agreement) shares of Skyworks common stock issued in exchange for each outstanding share of AATI common stock. This information shows how each share of AATI common stock would have participated in the combined company’s income from operations and book value if the merger had been completed on the relevant dates. These amounts do not necessarily reflect expected future per share amounts of net income from operations and book value of the combined company.

The following unaudited comparative per share data are derived from the historical consolidated financial statements of each of Skyworks and AATI. Skyworks and AATI historical results have different year end dates and different interim period ending dates for each quarter. For further details regarding the basis of presentation see Note 1, Basis of Pro Forma Presentation of the accompanying Notes to the Unaudited Pro Forma Condensed Combined Financial Statements. The information below should be read in conjunction with the audited and unaudited consolidated financial statements and accompanying notes of Skyworks, which are incorporated by reference into this proxy statement/prospectus, and of AATI, which are incorporated by reference into this proxy statement/prospectus. You are urged to also read “Skyworks and AATI Unaudited Pro Forma Condensed Combined Financial Statements” beginning on page [ • ]. The unaudited pro forma combined per share information does not purport to represent what the actual results of operations of Skyworks and AATI would have been had the companies been combined during these periods or to project Skyworks and AATI’s results of operations that may be achieved after the merger.

SKYWORKS AND AATI UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS

The unaudited pro forma condensed combined statements of operations for the six months ended April 1, 2011 and for the twelve months ended October 1, 2010 give effect to the transaction as if it was consummated on October 3, 2009 (the first day of Skyworks’s fiscal 2010) and include all adjustments which give effect to events that are directly attributable to the transaction, expected to have a continuing impact beyond a 12-month period and that are factually supportable. The unaudited pro forma condensed combined balance sheet as of April 1, 2011 gives effect to the transaction as if it had been consummated on April 1, 2011 and includes all adjustments which give effect to events that are directly attributable to the transaction and that are factually supportable. The notes to the pro forma financial information describe the pro forma amounts and adjustments presented below.

Skyworks and AATI have different fiscal year ends and have different interim period ending dates for each quarter. Accordingly, the unaudited pro forma condensed combined statement of operations for the six months ended April 1, 2011 combines the unaudited historical results of Skyworks for the six months ended April 1, 2011 and the unaudited historical results of AATI for the six months ended March 31, 2011 derived from the audited historical results for the year ended December 31, 2010 less the unaudited nine months ended September 30, 2010 plus the unaudited three months ended March 31, 2011. The unaudited pro forma condensed combined statement of operations for the fiscal year ended October 1, 2010 combines the audited historical results of Skyworks for the twelve months ended October 1, 2010 and the unaudited historical results of AATI for the twelve months ended September 30, 2010, derived from the audited results for the year ended December 31, 2010 less the unaudited three months ended December 31, 2010 plus the three months ended December 31, 2009. Both the unaudited pro forma condensed combined statement of operations for the six months ended April 1, 2011 and the twelve months ended October 1, 2010 give effect to the merger as if it had been completed on October 3, 2009. For presentation purposes, the differing interim period ending dates for each quarter are considered to be immaterial to the condensed combined financial statements.

The pro forma adjustments reflecting the consummation of the transaction are based upon the acquisition method of accounting in accordance with U.S. GAAP, and upon the assumptions set forth in the notes herein. The unaudited pro forma condensed combined balance sheet has been adjusted to reflect the preliminary allocation of the estimated purchase price to identifiable net assets acquired and the excess purchase price to goodwill. The allocation of the purchase price is preliminary and based on valuations derived from estimated fair value assessments and assumptions used by management. The estimated purchase price was calculated based upon the fixed consideration of $6.13 per share of AATI to be delivered in a combination of cash and Skyworks common stock. The final purchase price allocation will be based on the actual net tangible and intangible assets of AATI that will exist on the effective time of the merger. Additionally, the estimated purchase price and related cash and stock components are preliminary and will be adjusted based upon the price per share of Skyworks common stock over the five day averaging period preceding the effective time of the merger. The estimated cash and equity components of consideration are based on the average last sale price of Skyworks common stock over the 30 trading days prior to May 26, 2011, which for these purposes is assumed to be $26.84, the closing price of Skyworks common stock on May 25, 2011. Accordingly, the final purchase accounting adjustments may be materially different from the preliminary pro forma adjustments presented herein.

The unaudited pro forma condensed combined financial statements do not include the effects of any future restructuring activities, including severance or other employee related costs, which pertain to the combined operations, or other operating efficiencies or inefficiencies, which may result from the transaction but are either non-recurring or at this point not factually supportable. Furthermore, the unaudited pro forma condensed combined financial statements do not include any effects on revenue recognition due to employing Skyworks’ terms and business practices. Also, the unaudited pro forma condensed combined statements of operations do not include certain non-recurring expenses directly attributable to the transaction, such as (i) for accelerated vesting of share based compensation, (ii) for transaction related expenses and (iii) for any restructuring related costs pertaining to this acquisition . Therefore, the unaudited pro forma condensed combined financial information is not necessarily indicative of results that would have been achieved had the

businesses been combined as of the dates presented or the results that Skyworks will experience after the transaction is consummated. In addition, the preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. These estimates and assumptions are preliminary and have been made solely for purposes of developing this pro forma information. Actual results could differ materially from these estimates and assumptions.

The unaudited pro forma condensed combined financial information should be read in conjunction with the financial information appearing under “Selected Historical Consolidated Financial Data of Skyworks” beginning on page [ • ] and “Selected Historical Consolidated Financial Data of AATI” beginning on page [ • ], as well as Skyworks’ historical consolidated financial statements and accompanying notes in its Annual Report on Form 10-K as of and for the fiscal year ended October 1, 2010 and its Quarterly Report on Form 10-Q as of and for the fiscal quarter ended April 1, 2011, and AATI’s historical consolidated financial statements and accompanying notes in its Annual Report on Form 10-K as of and for the year ended December 31, 2010 and its Quarterly Report on Form 10-Q as of and for the three months ended March 31, 2011.

Notes to Unaudited Pro Forma Condensed Combined Financial Statements


Note 1:	Basis of Pro Forma Presentation

The merger agreement provides for the merger of Merger Sub, a wholly owned subsidiary of Skyworks, into AATI. The unaudited pro forma condensed combined balance sheet combines the unaudited historical consolidated balance sheet of Skyworks as of April 1, 2011 and the unaudited historical consolidated balance sheet of AATI as of March 31, 2011 and gives effect to the merger as if it had been completed on April 1, 2011. Skyworks and AATI have different fiscal year ends and have different interim period ending dates for each quarter. Accordingly, the unaudited pro forma condensed combined statement of operations for the six months ended April 1, 2011 combines the unaudited historical results of Skyworks for the six months ended April 1, 2011 and the unaudited results of AATI for the six months ended March 31, 2011, derived from the audited historical results for the year ended December 31, 2010 less the unaudited nine months ended September 30, 2010 plus the unaudited three months ended March 31, 2011. The unaudited pro forma condensed combined statement of operations for the twelve months ended October 1, 2010 combines the audited historical results of Skyworks for the fiscal year ended October 1, 2010 and the unaudited results of AATI for the twelve months ended September 30, 2010, derived from the audited results for the year ended December 31, 2010 less the unaudited three months ended December 31, 2010 plus the unaudited three months ended December 31, 2009. Both the unaudited pro forma condensed combined statement of operations for the six months ended April 1, 2011 and the twelve months ended October 1, 2010 give effect to the merger as if it had been completed on October 3, 2009. Based on a preliminary assessment, we have not noted any significant differences between the two companies’ accounting policies.

Upon completion of the merger, each outstanding share of AATI common stock (except for shares held directly or indirectly by Skyworks, Merger Sub, AATI or any wholly owned subsidiary of AATI (which will be cancelled as a result of the merger), and except for shares held by stockholders exercising dissenter’s rights) will automatically become the right to receive an aggregate of $6.13 per share, payable in the form of 0.08725 of a share of Skyworks common stock (the “stock consideration”) and an adjustable cash amount in the initial calculated amount of $3.68 (the “cash consideration” and, together with the stock consideration, the “merger consideration”), without interest and less applicable withholding taxes. The final cash consideration will depend on the closing value of the stock consideration, calculated on the basis of Skyworks’ average reported last sale price in regular Nasdaq trading during a five-trading-day measurement period preceding the closing of the merger. If the closing value of the stock consideration is less than $2.45, the cash consideration will increase by the amount of the shortfall. If the closing value of the stock consideration is more than $2.45, the cash consideration will decrease by the amount of the excess. And if the closing value of the stock consideration is exactly $2.45, the cash consideration will remain unchanged at $3.68. In each case, the merger consideration will maintain a constant nominal aggregate combined value of $6.13 per share of AATI common stock. In addition, if Skyworks’ average reported last sale price during the pre-closing measurement period is less than $21.00, Skyworks has the right to pay the entire $6.13 per share in cash.

The pro forma presentation below assumes that the average last sale price of Skyworks common stock in the pre-closing measurement period is $26.84 (the same as the last sale price of Skyworks common stock on May 25, 2011), which would result in cash consideration of $3.79 and stock consideration of $2.34 ($26.84 x 0.08725) per outstanding share of AATI common stock (for total merger consideration of $6.13 per outstanding share of AATI common stock), and an option exchange ratio of 0.2284 ($6.13 ¸ $26.84).

Preliminary Purchase Price

The total estimated preliminary purchase price expected to be transferred to effect the merger is as follows (in millions except share and per share amounts):


Acquisition of 42.8 million shares of outstanding common stock of AATI at $3.79 per share in cash	$	162.2
Estimated fair value of Skyworks shares to be issued in exchange for 42.8 million shares of outstanding common stock of AATI (A1)	$	100.2
Assumption and conversion of approximately 7.2 million stock option awards of AATI employees into stock option awards to purchase Skyworks common stock with an estimated fair value of (A2):	$	23.7
Assumption and conversion of approximately 1.2 million shares of restricted share units of AATI employees into restricted share units to acquire Skyworks common stock with estimated fair value of (A2):	$	7.2

Estimated purchase price consideration	$	293.3

A1. The fair value of the Skyworks shares issued in exchange for outstanding shares of AATI common stock is computed as follows (in thousands, except per share data).


Shares of AATI common stock outstanding at March 31, 2011		42,800
Per share exchange ratio		0.08725

Number of shares of Skyworks common stock to be issued in the merger		3,734
Price per share of Skyworks Common Stock on May 25, 2011	$	26.84

Fair value of shares of Skyworks common stock to be issued in the merger	$	100,229

A2. Derived by applying a contractually defined exchange ratio of 0.2284 (assuming a $26.84 Skyworks average last reported sale price in the pre-closing measurement period) to all outstanding stock options and determining the estimated fair market value of such converted stock options using the Black-Scholes valuation methodology with the following assumptions:


Dividend Yield		0%
Volatility		49.3%
Risk Free Rate		1.59%
Expected Life		4.1 years
Effective Time Stock Price Assumed		$26.84 per share

We have estimated a fair value of $30.9 million for the Skyworks stock options and restricted stock units expected to be issued in the assumption and conversion of stock option and restricted stock units at the effective time of the merger in accordance with the merger agreement. The $30.9 million has been attributed to the preliminary estimate of purchase price which is subject to final purchase accounting and valuation in accordance with ASC 718 Compensation — Stock Compensation. The fair value of all unvested stock option and restricted stock units as of the effective time of the merger subject to future service conditions shall be recognized as stock compensation expense in future periods. Skyworks anticipates approximately $10.9 million in future compensation expense as a result of the assumption and conversion of options and restricted stock units.

Preliminary Purchase Price Allocation

The purchase price has been allocated based on a preliminary estimate of the fair value of net assets acquired as of April 1, 2011 (in thousands):


Preliminary Purchase Price Allocation:
Net book value of assets acquired	$	117,347
Less: impact to accumulated deficit for transaction related costs incurred by AATI		(6,104	)
Less: AATI goodwill and intangibles		(16,149	)

Adjusted net book value of assets acquired as of April 1, 2011		95,094
Increase in identifiable intangible assets		52,408
Increase in inventory to fair value		3,789
Increase in deferred tax assets to fair value		(1,132	)
Goodwill		143,112

Total net assets acquired	$	293,271


Note 2:	Pro Forma Adjustments

The pro forma adjustments included in the unaudited pro forma condensed combined financial statements are as follows:

A. Cash — Represents the estimated use of cash to fund the cash portion of the merger consideration. Management has assessed the impact of cash consideration paid on pro forma interest income. Based on our cash investment policy and the low interest rate environment, we have determined the impact to be de minimis.

B. Inventory — To record the difference between the historical book value and preliminary estimated fair values of AATI inventory acquired in the transaction. The impact of the fair value adjustment to inventory has not been reflected in the pro forma statement of operations given management’s assessment that it is non-recurring in nature.

C. Goodwill — To eliminate AATI historical goodwill and record the preliminary estimate of goodwill for the acquisition of AATI. The pro forma adjustment to goodwill includes the following (in thousands):


	AATI		Preliminary
	Historical		Estimated
	Amount		Fair Value		Increase

Goodwill	$	16,116	$	143,112	$	126,996

D. Intangible Assets — To reflect the estimated purchase price allocation to identifiable intangible assets acquired. These estimated fair values and useful lives are considered preliminary and are subject to change in accordance with ASC 805 Business Combinations. Changes in fair value or useful lives and associated amortization expense of the acquired intangible assets may be material. The acquired finite-

Note: In process research and development is estimated to be expensed within one year and was included in research and development in the twelve month Statement of Operations.

E. Deferred Tax Asset — To record the preliminary adjustments to reflect fair value of deferred tax assets acquired. Management has determined that it is more likely than not that it will be able to realize an additional $17.2 million of AATI’s deferred tax assets, resulting in a reduction to AATI’s existing valuation allowance. This net increase to the net deferred tax asset of $17.2 million is offset by the estimated deferred tax liability of $18.3 million associated with the estimated valuation of AATI’s intangible assets calculated at the statutory tax rate.

F. Other Current Liabilities — To record estimated current liabilities to be incurred which are directly attributable to the transaction including transaction related advisory fees, estimated cash change of control obligations and other professional fees. In accordance with ASC 805, Business Combinations, these amounts would be expensed as incurred. For the purposes of presenting the Unaudited Pro Forma Condensed Combined Statement of Operations for the twelve month period ended October 1, 2010, does not reflect such expenses as they would have been incurred prior to the Effective Date.

G. Equity — Adjustments to shareholders’ equity represents the elimination of AATI’s historical shareholders’ equity and the issuance of approximately 3.7 million shares of Skyworks common stock upon completion of the transaction. The estimated value of Skyworks’ shares to be issued is approximately $100.2 million based on the assumed exchange ratio of 0.08725 per each share of Skyworks common stock and the assumed Skyworks average last reported sale price in the pre-closing measurement period of $26.84 per share. (The actual Skyworks average last reported sales price in the pre-closing measurement period will be calculated at or prior to closing and may be higher or lower than $26.84.) Also reflected is an adjustment to record an estimated $30.9 million in fair value of Skyworks options and restricted stock units to be issued upon the assumption and conversion of those of AATI.

H. Provision (benefit) for income taxes — To reflect the estimated tax benefit associated with the combined Company’s ability to utilize AATI’s net loss for the period and the tax impact of the amortization expense at the statutory rate. These amounts are preliminary estimates and may differ materially in actual future results of operations.


Note 3.	Pro Forma Net Income Per Share

Pro forma basic and diluted net income per share is calculated by dividing the pro forma combined net income by the pro forma weighted-average number of shares outstanding. The pro forma basic and diluted net income per share amounts presented in the unaudited pro forma condensed combined statements of operations are based on the weighted-average number of Skyworks common stock outstanding and are adjusted for additional shares issued in the merger.

THE SPECIAL MEETING

Date, Time, Place and Purpose of the Special Meeting

This proxy statement/prospectus is being furnished to AATI’s stockholders as part of the solicitation of proxies by the AATI board of directors for use at the special meeting to be held on [ • ], starting at [ • ] a.m. Pacific daylight time, at the offices of Wilson Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo Alto, California 94304, or at any postponement or adjournment thereof. The purpose of the special meeting is for AATI’s stockholders to consider and vote on:


	•	a proposal to adopt the merger agreement and to approve the merger, the terms of which provide, among other things, for the merger of Merger Sub with and into AATI, with AATI surviving the merger as a wholly owned subsidiary of Skyworks, and the conversion of each share of AATI common stock outstanding immediately prior to the effective time of the merger (other than shares held in treasury of AATI or owned, directly or indirectly, by Skyworks, Merger Sub or any subsidiary of AATI) into the right to receive a combination of cash and Skyworks common stock with a nominal aggregate combined value of $6.13 per share of AATI common stock, consisting of 0.08725 of a share of Skyworks’ common stock, par value $0.25 per share, and cash in the initial calculated amount of $3.68 (subject to adjustment up or down as set forth in the merger agreement);

	•	a proposal to approve, by non-binding, advisory vote, certain compensation arrangements for AATI’s named executive officers and directors in connection with the merger;

	•	a proposal to adjourn the special meeting to a later date or time, if necessary or appropriate, to solicit additional proxies in the event there are insufficient votes at the time of the special meeting to approve and adopt the merger agreement; and

	•	such other business as may properly come before the special meeting by or at the direction of AATI’s board of directors or any adjournments or postponements of the special meeting.

AATI does not expect a vote to be taken on any other matters at the special meeting. If any other matters are properly presented at the special meeting for consideration, the holders of proxies, if properly authorized, will have discretion to vote on those matters in accordance with their best judgment.

Record Date and Quorum

AATI has fixed the close of business on [ • ], 2011 as the record date for the special meeting, and only holders of record of AATI common stock at the close of business on the record date are entitled to notice of and to vote at the special meeting and any adjournments or postponements thereof (unless the board of directors fixes a new record date for any such postponed or adjourned meeting). As of the record date, there were [ • ] shares of AATI common stock outstanding and entitled to vote. Each holder of record of AATI common stock on the record date will be entitled to one vote for each share owned of record as of the close of business on the record date. A majority of the votes entitled to be cast by holders of issued and outstanding shares of AATI common stock constitutes a quorum for the purpose of the special meeting. Shares of AATI common stock present in person or represented at the special meeting but not voted, including shares of AATI common stock for which proxies have been received but for which stockholders have abstained, will be treated as present at the special meeting for purposes of determining the presence or absence of a quorum for the transaction of all business. In the event that a quorum is not present at the special meeting, the special meeting may be adjourned or postponed to solicit additional proxies.

Vote Required for Approval

Adoption of the merger agreement and approval of the merger requires the affirmative vote of at least a majority of all of the votes entitled to be cast by holders of the shares of AATI common stock that are issued and outstanding as of the record date and entitled to vote thereon. Therefore, if you abstain or fail to vote, it will have the same effect as a vote “AGAINST” the adoption of the merger agreement and approval of the merger. In addition, if your shares are held in street name by a broker or other nominee, your broker or other

nominee will not be entitled to vote your shares on the proposal to adopt the merger agreement and approve the merger in the absence of specific instructions from you. These non-voted shares will have the same effect as a vote “AGAINST” the adoption of the merger agreement and approval of the merger.

Approval of the non-binding, advisory vote regarding certain merger-related executive compensation arrangements requires the affirmative vote of holders of a majority of the shares of AATI common stock present in person or represented by proxy and entitled to vote thereon. Abstaining will have the same effect as a vote “AGAINST” the non-binding proposal regarding certain merger-related executive compensation arrangements. If you fail to vote or if you fail to provide your broker with instructions on the proposal, your shares will not be counted as shares present and entitled to vote on the proposal to adjourn the special meeting and will have no effect on the proposal. Stockholders should note that the proposal regarding certain merger-related executive compensation arrangements is merely an advisory vote which will not be binding on AATI, Skyworks or AATI’s board of directors.

The adoption of the proposal to adjourn the special meeting to a later time, if necessary or appropriate, to solicit additional proxies requires the votes cast favoring the action to exceed the votes cast opposing the action. Therefore, if you abstain or fail to vote, it will have no effect on the outcome of the proposal to adjourn the special meeting. If you fail to provide your broker with instructions on the proposal, your shares will not be counted as shares present and entitled to vote on the proposal to adjourn the special meeting and will have no effect on the vote to adjourn the special meeting.

Voting by Directors and Executive Officers of AATI

As of the record date for the AATI special meeting, AATI’s directors, executive officers and their affiliates, as a group, beneficially owned and were entitled to vote an aggregate of [ • ] shares of AATI common stock, or [ • ] percent of the total outstanding shares of AATI common stock as of the record date.

In connection with the merger agreement, as a condition to Skyworks’ entering into the merger agreement, Skyworks entered into a stockholder agreement with certain of the officers and directors of AATI (namely, Richard K. Williams, Samuel J. Anderson, Jason L. Carlson, Jaff Lin, Thomas P. Redfern, Chandramohan Subramanian, Jun-Wei Chen, Ashok Chandran and Kevin D’Angelo). Pursuant to the stockholder agreement, each signing stockholder has agreed to vote all shares of AATI common stock beneficially owned by such stockholder in favor of adoption of the merger agreement and approval of the merger and the other transactions contemplated by the merger agreement and against any other acquisition proposal or alternative acquisition agreement made in opposition to the consummation of the merger and the transactions contemplated by the merger agreement. The signing stockholders have also granted Skyworks an irrevocable proxy to vote their shares of AATI common stock at any meeting of AATI stockholders called with respect to the adoption of the merger agreement and approval of the merger and the other transactions contemplated by the merger agreement.

The signing stockholders own 2,576,028 issued and outstanding shares of AATI common stock and options currently vested or vesting in the 60 days following May 26, 2011 (without giving effect to any acceleration that may occur upon consummation of the merger) that are exercisable for 2,430,725 shares of AATI common stock, representing, in the aggregate 11.03% of the 42,971,079 shares outstanding as of May 24, 2011. Under the terms of the stockholder agreement, any shares of AATI common stock received upon the exercise of stock options or the settlement of restricted stock units by the stockholders who have signed the stockholder agreement are subject to the provisions of the stockholder agreement.

The stockholder agreement terminates upon the earlier to occur of the effective time of the merger or any termination of the merger agreement in accordance with its terms, and the proxy granted to Skyworks terminates automatically upon termination of the stockholder agreement.

Proxies and Revocation

Stockholders of record as of the close of business on the record date may vote their shares of AATI common stock by:


	•	submitting their proxy by telephone by following the instructions on the enclosed proxy card;

	•	submitting their proxy over the Internet by following the instructions on the enclosed proxy card;

	•	signing, dating and returning the enclosed proxy card in the accompanying pre-addressed, postage-paid envelope; or

	•	appearing and voting in person at the special meeting.

Whether or not you plan to attend the special meeting in person, AATI requests that you complete, sign, date and return the enclosed proxy card or submit your proxy by telephone or over the Internet prior to the special meeting to ensure that your shares will be voted at the special meeting. If you properly authorize a proxy but no direction is given on how to vote your shares, your shares will be voted “FOR” the adoption of the merger agreement and approval of the merger, “FOR” the approval of the non-binding, advisory proposal regarding certain merger-related executive compensation arrangements and “FOR” the adjournment of the special meeting, if necessary or appropriate, to solicit additional proxies, and in accordance with the discretion of the proxies on any other matters properly brought before the special meeting, or at any adjournment or postponement thereof.

If your shares of AATI common stock are held in “street name” by a broker or other nominee, you will receive a voting instruction form from your broker or other nominee with instructions that you must follow in order to have your shares voted. If you have not received such voting instructions or require further information regarding such voting instructions, contact your broker or other nominee. Brokers who hold shares of AATI common stock in “street name” for a beneficial owner of those shares typically have the authority to vote in their discretion on “routine” proposals when they have not received instructions from beneficial owners. However, brokers will not have such discretion with respect to the proposals contained in this proxy statement/prospectus as such proposals are not considered “routine” proposals. Therefore, if you do not provide voting direction to your broker or other nominee in accordance with the instructions provided by such broker or other nominee your shares held in “street name” will not be voted. Accordingly, such uninstructed shares will have the effect of votes “AGAINST” the adoption of the merger agreement and approval of the merger, but will have no effect on the non-binding, advisory proposal regarding certain merger-related executive compensation arrangements or on the proposal to adjourn the special meeting.

Proxies received by AATI at any time before the vote is taken at the special meeting, which have not been revoked or changed before being voted, will be voted at the special meeting. If you are a stockholder of record of shares of AATI common stock, you have the right to change or revoke your proxy at any time, unless noted below, before the vote is taken at the special meeting:


	•	by delivering to AATI’s principal executive offices at 3230 Scott Boulevard, Santa Clara, CA 95054, Attn: Corporate Secretary, a signed written notice of revocation bearing a date later than the date of the proxy, stating that the proxy is revoked;

	•	by attending the special meeting and voting in person (your attendance at the meeting will not, by itself, revoke your proxy; you must vote in person at the meeting);

	•	by signing and delivering a new proxy, relating to the same shares of AATI common stock and bearing a later date; or

	•	by submitting a new proxy by telephone or over the Internet on a later date but prior to the date of the special meeting.

If you are a “street name” holder of AATI common stock, you may change or revoke your vote by submitting new voting instructions to your broker or other nominee. You must contact your broker or other nominee to obtain instructions as to how to change or revoke your proxy.

If you have any questions or need assistance in voting your shares, please call Innisfree, the firm assisting AATI in the solicitation of proxies:

Banks and Brokers may call collect: 212-750-5833

Adjournments and Postponements

Although it is not currently expected, the special meeting may be adjourned or postponed for any reason. The DGCL, provides that, unless a company’s bylaws provide otherwise, if a special meeting of stockholders is adjourned to a different date, time or place, the company is not required to give notice of the new date, time or place if adjournment is not for more than 30 days. AATI’s amended and restated bylaws do not provide otherwise. In the event that a quorum is not present at the special meeting, the special meeting may be adjourned or postponed to solicit additional proxies. If a quorum is present, approval of a proposal submitted to stockholders to adjourn the meeting requires the votes cast favoring the action to exceed the votes cast opposing the action. Abstentions will have no effect on a proposal to adjourn the meeting. Any adjournment of the special meeting for the purpose of soliciting additional proxies will allow AATI’s stockholders who have already sent in their proxies to revoke them at any time prior to their use at the special meeting as adjourned or postponed.

Solicitation of Proxies

Shareholders should not submit any stock certificates with their proxy cards. A letter of transmittal with instructions for the surrender of certificates representing shares of AATI common stock will be mailed to AATI’s stockholders if the merger is completed. AATI has retained Innisfree M&A, Inc. (“Innisfree”) to assist it in the solicitation of proxies. AATI expects to pay Innisfree a fee not to exceed $20,000 for its services. AATI will also pay additional fees to Innisfree depending upon the extent of additional services requested by AATI and reimburse Innisfree for expenses it incurs in connection with its engagement by AATI. AATI’s directors, officers and employees may also solicit proxies by personal interview, mail, e-mail, telephone, facsimile or other means of communication. These persons will not be paid additional remuneration for their efforts. AATI also will request that banking institutions, brokerage firms, custodians, trustees, nominees, fiduciaries and other like record holders forward the solicitation materials to the beneficial owners of common stock held of record by such person, and AATI will, upon request of such record holders, reimburse forwarding charges and out-of-pocket expenses.

THE MERGER

This discussion of the merger is qualified in its entirety by reference to the merger agreement, which is attached to this proxy statement/prospectus as Annex A and which is incorporated by reference into this proxy statement/prospectus. You should read the entire merger agreement carefully as it is the legal document that governs the merger.

Background of the Merger

AATI’s board of directors and management regularly review and discuss AATI’s business plan, strategic opportunities and challenges. These reviews and discussions focus, among other things, on the business and competitive environment facing the semiconductor industry in general and AATI in particular. These reviews also include periodic discussions regarding potential transactions that could further AATI’s strategic objectives and enhance stockholder value, as well as the potential benefits and risks of those transactions.

For several years prior to 2011, Skyworks had included AATI as an acquisition candidate on lists presented from time to time to Skyworks’ board of directors. Skyworks believed that a relationship with AATI would bolster Skyworks’ diversified analog business.

During the spring of 2010, Mr. Liam Griffin (at that time, Skyworks’ senior vice president of sales, and subsequently Skyworks’ executive vice president and general manager, high performance analog), telephoned Mr. Samuel Anderson (chairman of the board of directors of AATI), and asked Mr. Anderson if he would be open to talking to Mr. David Aldrich (Skyworks’ president and chief executive officer) about possible collaboration opportunities between Skyworks and AATI. Mr. Griffin and Mr. Anderson had become acquainted through their common service as directors of a third company. Mr. Anderson indicated that he would be open to a taking such call, and Mr. Aldrich telephoned Mr. Anderson to indicate a general interest in exploring possible business opportunities between AATI and Skyworks or a possible acquisition of AATI by Skyworks. Mr. Anderson and Mr. Richard Williams (president, chief executive officer and chief technical officer of AATI) subsequently met with Mr. Aldrich and held preliminary discussions to familiarize each other with their respective companies and to discuss collaboration or strategic relationship possibilities. Mr. Anderson and Mr. Aldrich followed up this meeting with additional telephonic discussions with respect to potential strategic relationships between AATI and Skyworks.

In late June 2010, Mr. Griffin spoke to Mr. Anderson about a possible collaboration meeting between Skyworks and AATI teams in July, and on July 21, 2010, Mr. Aldrich, Mr. Griffin, Mr. Thomas Schiller (Skyworks’ vice president, corporate development), and Skyworks marketing and engineering executives held a collaboration meeting with Mr. Anderson and Mr. Williams in Woburn, Massachusetts, where Skyworks is headquartered.

In late July 2010, a third party (“Company A”) also expressed an interest in a potential strategic transaction with AATI. Company A had earlier expressed an interest to another member of AATI’s board in late 2009 and early 2010 in exploring a strategic transaction with AATI. Mr. Anderson held a discussion with representatives of Company A to better understand the potential strategic fit between the companies.

On July 26, 2010, Mr. Aldrich spoke with Mr. Anderson and proposed that Skyworks acquire AATI. Mr. Anderson proposed that Mr. Aldrich meet Mr. Williams and members of the AATI board in Santa Clara, California, where AATI is headquartered, to continue discussions.

On July 27, 2010, the board of directors of AATI held a regularly scheduled meeting at which Mr. Anderson informed the board that Mr. Aldrich had expressed an interest in collaboration, and potentially a strategic transaction, with AATI. Mr. Anderson also informed the board of the continued potential interest of Company A in a strategic transaction with AATI, and he updated the board on his discussion with Company A. The board of directors instructed Mr. Anderson to continue these discussions with both Skyworks and Company A as part of the Board’s exploration of strategic alternatives for AATI.

In August 2010, Mr. Anderson held an additional discussion with Company A about a potential strategic transaction. The key individual at Company A holding discussions with Mr. Anderson changed positions

during this timeframe, and further discussions terminated without Company A proposing specific terms of a strategic transaction.

In late August 2010, Mr. Anderson held telephone conversations with Mr. Aldrich for the purpose of confirming the AATI board meeting to be held in September 2010 at which Mr. Aldrich would be making a presentation.

On September 22, 2010, the AATI board of directors held a regularly scheduled meeting in Santa Clara, California. At this meeting, Mr. Aldrich and Mr. Griffin presented to the AATI board a potential plan and business rationale for a strategic transaction between AATI and Skyworks.

On September 23, 2010, Mr. Anderson communicated to Mr. Aldrich that the AATI board was in favor of exploring both a potential collaboration with Skyworks and a potential acquisition of AATI by Skyworks in parallel.

The parties then scheduled a meeting for October 28, 2010 to discuss valuation and intellectual property issues, including litigation matters in particular. In mid-October 2010, in preparation for that meeting, Skyworks engaged the law firm of Wilmer Cutler Pickering Hale and Dorr LLP (“WilmerHale”) to assist with the proposed acquisition and to perform a preliminary review of intellectual property litigation and other legal issues related to the proposed acquisition.

On October 20, 2010, the AATI board of directors held a regularly scheduled meeting. At this meeting, the board discussed recent discussions between Skyworks and AATI, and the board authorized Mr. Anderson to continue these discussions. The board also discussed a recent opportunity to explore a strategic transaction with a different third party (“Company B”). Mr. Anderson noted to the board that a stockholder of AATI had informed him of Company B’s potential interest in a relationship with AATI. The board authorized Mr. Anderson to enter into discussions with Company B to better understand the potential for a strategic transaction with Company B.

On October 24 and 25, 2010, Mr. Aldrich and Mr. Anderson met in Boston, Massachusetts. They discussed the possibility of an acquisition of AATI by Skyworks and began a preliminary valuation discussion.

On October 28, 2010, Mr. Anderson, Mr. Williams and Mr. Joe Hollinger (general counsel of AATI) met in Woburn, Massachusetts with Mr. Aldrich and Skyworks’ chief IP counsel and senior director of intellectual property to discuss intellectual property issues, with a particular focus on the status of AATI’s then on-going litigation with Linear Technology Corporation (“LTC”). Mr. Aldrich and Mr. Anderson also discussed AATI’s valuation concerns.

On November 1, 2010, the AATI board of directors held a special meeting to discuss both the status of recent interactions with Skyworks as well as AATI’s long-term strategic planning process. In the course of these discussions, the AATI board of directors noted that it believed that it was timely and appropriate to evaluate AATI’s prospects as a stand-alone company, to work with AATI’s management to develop strategies to improve AATI’s competitive position and to conduct a focused effort to increase long-term stockholder value. In connection with this discussion, representatives of Wilson Sonsini Goodrich & Rosati, Professional Corporation (“WSGR”), AATI’s outside corporate legal counsel, reviewed with the directors their fiduciary duties in connection with considering strategic transactions and addressed questions of the board. In addition, the board determined that, given the productive interactions to date between Mr. Anderson and the Skyworks representatives, Mr. Anderson should continue to serve as the primary AATI representative in such discussions. The board directed Mr. Anderson to keep the board promptly informed of any significant developments in these discussions.

On November 3, 2010, Mr. Anderson communicated to Mr. Aldrich that he had discussed Skyworks’ acquisition offer with the members of AATI’s board of directors, and that the members of the board were generally receptive to the possibility of an acquisition of AATI by Skyworks, but that AATI needed additional detail regarding the terms of the proposed acquisition. On November 8, 2010, Mr. Aldrich provided additional details regarding the terms contemplated by Skyworks.

On November 12, 2010, Skyworks sent a proposal to AATI, contemplating an acquisition of AATI by Skyworks at a price of $6.34 per share.

On November 18, 2010, Mr. Anderson met with the chief executive officer of Company B to discuss potential alternative strategic transactions.

On November 19, 2010, the AATI board of directors held a regularly scheduled meeting at which a proposed business combination with Skyworks was discussed. The board reviewed the terms of the recent Skyworks’ proposal. Representatives of WSGR discussed the board’s fiduciary duties and addressed questions of the board. The board also instructed Mr. Anderson to continue discussions with Skyworks.

On November 22, 2010, Mr. Anderson informed Skyworks that AATI’s board of directors had a number of issues with Skyworks’ proposal and requested a conference call to discuss the issues.

On December 1, 2010, AATI executives, including Mr. Williams, held a meeting with the chief executive officer of Company B to discuss a potential strategic transaction.

On December 1, 2010, Mr. Aldrich informed Mr. Anderson that Skyworks was willing to make certain changes that AATI had requested to Skyworks’ November 12 proposal. At the same time, Mr. Aldrich stated that Skyworks wanted exclusivity between Skyworks and AATI, and also wanted AATI not to make any acquisitions while Skyworks and AATI were in discussions looking toward the acquisition of AATI by Skyworks.

On December 2, 2010, Skyworks presented a revised proposal to AATI contemplating an acquisition price of $7.00 per share.

On December 9, 2010, Mr. Aldrich and Mr. Anderson discussed Skyworks’ December 2, 2010 proposal and Skyworks’ request for exclusivity. On December 13, 2010, Skyworks further revised its proposal to AATI to increase the proposed price to $7.25 per share.

On December 14, 2010, the board of directors of AATI held a special telephonic meeting at which Mr. Anderson reviewed the recent discussions with Skyworks and the revised proposal. After extensive discussion, the board of directors of AATI instructed Mr. Anderson to continue discussions with Skyworks, with a focus on increasing the offer price and understanding the proposed form of consideration and other key terms. Following the AATI board meeting, Mr. Anderson relayed a number of questions to Mr. Aldrich regarding the structure and terms of the proposed transaction, including whether the transaction was all stock, all cash, or a combination and whether AATI would have representation on the Skyworks board.

On December 17, 2010, Mr. Aldrich responded to Mr. Anderson’s questions and indicated that Skyworks was willing to pay all cash, all stock, or a combination of cash and stock. Mr. Aldrich also indicated he was comfortable with the current size and composition of the Skyworks board of directors and therefore would only be open to considering board representation for AATI in the event that a current Skyworks director left the board.

On December 17, 2010, the board of directors of AATI held a special telephonic meeting at which Mr. Anderson reviewed the recent discussions with Skyworks. The board of directors of AATI directed Mr. Anderson to continue discussions with both Skyworks and Company B.

On December 20, 2010, members of management of AATI and Company B met and conducted due diligence on each other regarding a potential strategic transaction. Later in December 2010, Mr. Anderson also held several telephone conversations with the chief executive officer of Company B to discuss a potential strategic transaction.

On or about December 23, 2010, Company B indicated that it would be willing to enter into negotiations for the acquisition of AATI at a valuation of no higher than approximately $5.30 per share, based upon a proposed premium percentage and subject to further due diligence and negotiation of the terms of a definitive agreement.

On December 23, 2010, the board of directors of AATI held a special telephonic meeting at which the board reviewed Company B’s proposal. The board of directors noted that Company B’s proposal appeared substantially inferior to the most recent Skyworks proposal. As a result, and because of Company B’s stated intention that it would not offer more than approximately $5.30 per share, the board of directors determined that AATI should focus its efforts on a potential transaction with Skyworks. The board directed Mr. Anderson to seek an increase in the offer price by Skyworks and to inform Company B that AATI intended to cease discussions with it as this time. Immediately following this meeting, Mr. Anderson held a telephone conversation with the chief executive officer of Company B, informing Company B that its proposal was substantially below another potential offer. Company B confirmed that it would decline to proceed with further discussions with AATI. After the meeting, Mr. Anderson also informed Mr. Aldrich that the two companies were close to agreement on terms but that AATI would not be willing to grant exclusivity to Skyworks without a firm price of $7.50 per share and one seat on the Skyworks board of directors.

On December 27, 2010, Mr. Aldrich counter-proposed to Mr. Anderson a purchase price of $7.35 per share. Mr. Aldrich also indicated that a Skyworks’ board seat was not available, but that Skyworks would consider an arrangement by which an AATI representative could participate in Skyworks’ board meetings as an observer. On December 29, 2010, Mr. Anderson verbally agreed to present these proposed terms to the AATI board.

On January 6, 2011, Skyworks presented AATI with a proposed non-binding letter of intent, executed by Mr. Schiller on behalf of Skyworks, contemplating a price of $7.35 per share, an all-stock transaction with a fixed exchange ratio and no price protection, and an exclusivity period of 45 days. The offered price represented a premium of approximately 87% to AATI’s closing price of $3.94 on January 6, 2011.

On January 7, 2011, the board of directors of AATI held a special telephonic meeting at which Mr. Anderson reviewed the recent discussions with Skyworks and the proposed non-binding letter of intent, particularly the contemplated 45-day exclusivity period during which time AATI would be prohibited from considering other competing bids to acquire AATI. Representatives of WSGR reviewed with the directors their fiduciary duties in connection with considering the transaction and addressed questions of the board. The board reviewed potential synergies of a combination as well as potential benefits and risks of the transaction to AATI and its stockholders. The board also discussed a preliminary timeline and structural and legal aspects of the transaction. The board reviewed the advisability of engaging a financial advisor to advise the board on the reasonableness of the terms under discussion. The board directed Mr. Anderson to engage Needham & Company, an investment banking firm familiar with AATI and its business, as AATI’s financial advisor.

On January 9, 2011, the AATI board of directors held a special telephonic meeting at which representatives from Needham & Company reviewed the terms of the proposed non-binding letter of intent, including the contemplated 45-day exclusivity period. Representatives of Needham & Company discussed the proposal with the board and provided input on the proposed terms of the transaction from a financial point of view. The AATI board of directors indicated that based on the level of the prior offer from Company B and the significant premium over recent trading prices that the Skyworks offer represented, the board believed that a modest exclusivity period would be a reasonable restriction to accept. After extensive discussion, the board unanimously approved entering into the non-binding letter of intent with Skyworks and authorized Mr. Anderson to sign and deliver the letter of intent to Skyworks.

On January 9, 2011, Mr. Anderson signed and delivered the non-binding letter of intent on behalf of AATI. Shortly thereafter, Skyworks delivered to AATI a list of information requirements and a proposed calendar for “due diligence” meetings.

Between January 9 and January 15, 2011, AATI’s outside legal counsel, WSGR, and Skyworks’ outside legal counsel, WilmerHale, negotiated the terms of a confidentiality, exclusivity and standstill agreement, which the parties signed and delivered on January 17, 2011, with effect from January 15, 2011. The agreement included a mutual one-year standstill agreement, a mutual two-year employee non-solicitation agreement, and a 45-day exclusivity period (to March 1, 2011) during which AATI agreed not to solicit acquisition proposals from any other party or to hold merger discussions with any other party.

On January 17, 2011, AATI formally engaged Needham & Company to act as AATI’s financial advisor.

On January 17, 18, and 19, 2011, Skyworks executives and lawyers from WilmerHale met in Palo Alto, California with Mr. Anderson, Mr. Williams and other AATI directors and executives, heard management presentations and overviews of AATI from AATI representatives, and conducted “due diligence” of various matters relating to AATI, including intellectual property and litigation matters.

On January 20, 2011, the board of directors of AATI held a special telephonic meeting at which the board also emphasized the importance of performing reverse due diligence on Skyworks, given the likely stock component of the consideration to be issued in a potential transaction.

In January and February 2011, Skyworks business and legal executives and representatives of Skyworks’ outside legal counsel at WilmerHale conducted extensive due diligence on AATI’s business, operations, intellectual property, litigation, financial condition and prospects, including several meetings in both California and Massachusetts. In addition, Skyworks executives toured AATI facilities in Asia. In particular, the parties spent a substantial amount of time discussing AATI’s then-ongoing intellectual property litigation with LTC. During this same period, Mr. Anderson and other AATI representatives and outside consultants also conducted “reverse diligence” with representatives of Skyworks to elicit information concerning Skyworks. These due diligence efforts continued despite the expiration of the 45-day exclusivity period between the parties.

On February 1, 2011, at a regularly scheduled meeting, Skyworks’ board of directors received an update briefing on the status discussions between AATI and Skyworks.

On February 2, 2011, the AATI board of directors held a regularly scheduled meeting at which Mr. Anderson updated the board on the due diligence process being undertaken by Skyworks.

On February 17, 2011, the AATI board of directors held a special telephonic meeting at which Mr. Anderson provided an additional update on the due diligence process being undertaken by Skyworks.

On February 24, 2011, Skyworks business and legal executives and outside counsel from WilmerHale held meetings with Mr. Williams, Mr. Anderson and AATI lawyers to discuss AATI’s then-ongoing intellectual property litigation with LTC.

On February 25, 2011, the AATI board of directors held a special telephonic meeting at which Mr. Anderson updated the board on recent due diligence sessions between Skyworks and AATI and, in particular, Skyworks’ remaining concerns with respect to AATI’s then-ongoing litigation with LTC. The board noted that the 45-day exclusivity period with Skyworks would expire soon, and the board discussed what, if any, additional market check efforts would be advisable under the circumstances. The board also discussed the risk that conducting a market check at this point in negotiations with Skyworks, which the board believed had been proceeding in good faith by both parties, could cause Skyworks to terminate discussions. In particular, the board noted that Mr. Aldrich had repeatedly expressed to Mr. Anderson that Skyworks would not engage in a competitive bidding process to acquire AATI, and that Skyworks believed that the premium it was offering justified exclusive negotiations. After further discussion, the board decided that the risk of Skyworks terminating negotiations as a result of AATI contacting and engaging in discussions with potentially interested third parties outweighed the likelihood that initiating a further affirmative market check by soliciting acquisition offers would be reasonably likely to result in a superior offer.

On February 26, 2011, Mr. Anderson informed Mr. Aldrich and Mr. Schiller that he had held an update call with the AATI board the day before, and that the AATI board had approved the continuation of due diligence to allow Skyworks time to complete its financial model and for AATI to develop a plan for addressing Skyworks’ concerns regarding the then-ongoing intellectual property litigation. Continuing until the signing of the definitive merger agreement, the AATI and Skyworks transaction teams engaged in due diligence reviews with respect to the other party to the transaction.

On March 1, 2011, AATI’s exclusivity obligations to Skyworks expired, freeing AATI, among other things, to entertain and respond to any unsolicited acquisition offers that third parties might make.

In early March 2011, Skyworks informed AATI that the potential liability with respect to the then-ongoing litigation with LTC and AATI’s weakened forecasted financial results for the third and fourth quarters of 2011 would present a serious impediment to a transaction moving forward. Skyworks indicated that it would reconsider this position if AATI could settle the litigation with LTC on reasonable terms. At this point, the parties shifted the focus of their active efforts, with AATI pursuing a litigation settlement with LTC.

On March 14, 2011, the board of directors of AATI held a special telephonic meeting at which the board discussed Skyworks’ concerns with respect to AATI’s then-ongoing litigation with LTC. The board of directors noted that an upcoming court-directed mediation session between AATI and LTC provided an opportunity to explore the terms on which this litigation could be settled. The board of directors authorized Mr. Anderson and Mr. Williams to propose settlement to LTC within a specified range. Following this meeting, Mr. Anderson informed Mr. Aldrich that a mediation session with LTC would take place on March 24, 2011 and that the AATI board had authorized pursuing a “fast track” settlement.

On March 24, 2011, Mr. Anderson, Mr. Williams, Mr. Hollinger and AATI’s outside intellectual property litigation counsel participated in a mediation session with representatives of LTC. During this mediation, representatives of AATI and LTC agreed to settle all claims between the companies.

On March 25, 2011, the board of directors of AATI held a regularly scheduled meeting at which the board discussed the status of the anticipated litigation settlement, as well as its potential impact on acquisition negotiations with Skyworks. Following this meeting, Mr. Anderson indicated to Skyworks that AATI had tentatively resolved the LTC litigation.

On March 28, 2011, senior executives and representatives of Skyworks attended a meeting with Mr. Anderson, Mr. Williams and other representatives of AATI in Palo Alto, California to discuss the current status of AATI’s business and various financial models. Following the March 28 meeting, Skyworks concluded that the business outlook for AATI has deteriorated from the prior forecast.

On March 31, 2011, AATI entered into a settlement agreement with LTC that ended the litigation between the two companies through the settlement of an enforcement proceeding in the United States Court of Appeals for the Federal Circuit and an action in the United States District Court for the Northern District of California. Specific terms of the settlement were not publicly disclosed.

On April 3, 2011, Mr. Anderson delivered to Mr. Aldrich a copy of the signed settlement agreement between AATI and LTC. On April 4, 2011, Skyworks contacted Mr. Anderson to seek clarification of the AATI-LTC settlement agreement. On or about April 7, 2011, AATI and LTC entered into an addendum clarifying the AATI-LTC settlement agreement and provided a copy of the addendum to Skyworks.

On April 4, 2011, the AATI board of directors held a special telephonic meeting at which Mr. Anderson provided the board an update on discussions with Skyworks, including potential synergies. The board requested that Needham & Company analyze from a financial point of view potential alternative mixes of consideration, including an all-stock transaction or a combination of cash and Skyworks’ common stock.

On April 8, 2011, Skyworks executives met with Mr. Williams and other AATI executives to discuss AATI’s near-term sales funnel, demand from customers and future opportunities.

On or about April 13, 2011, Mr. Aldrich and Mr. Schiller informed Mr. Anderson that Skyworks had concerns about AATI’s forecast for growth in its business over the next two quarters in light of the downtrend in AATI’s business over the last three quarters. On April 14, 2011, Mr. Anderson attempted to address the concerns expressed by Skyworks. In addition, Mr. Anderson commented on the consideration for the transaction, indicating that he thought AATI’s board of directors would support a 50%-50% stock-cash deal.

On April 18, 2011, Mr. Schiller informed Mr. Anderson that Skyworks’ previous price indication was not supportable by AATI’s new, reduced financial outlook. Mr. Schiller and Mr. Anderson discussed a new price of $6.30 per share, comprised of 60% in cash and 40% in Skyworks stock. Subsequently, Mr. Anderson communicated to Mr. Schiller that if Skyworks could agree to a $6.30 per share minimum, with the stock portion of the consideration to be based on a fixed exchange ratio based on the closing price of a share of Skyworks common stock on April 18, 2011, he would take Skyworks’ proposal to AATI’s board of directors.

On April 19, 2011, Mr. Schiller communicated to Mr. Anderson that the framework proposed by Mr. Anderson would be acceptable to Skyworks.

On April 22, 2011, WilmerHale distributed an initial draft of a merger agreement to WSGR and AATI. The initial draft of the definitive merger agreement included a proposed price per share of $6.30, of which $3.75 would be paid in cash and the remainder would be issued in a fixed portion of a share Skyworks common stock valued at $2.55 determined by a 30-day trading average immediately prior to the signing of a definitive merger agreement.

On April 24, 2011, the board of directors of AATI held a special telephonic meeting at which the board discussed the draft of the definitive merger agreement presented by Skyworks. Representatives of Needham & Company reviewed the financial terms presented in the proposed definitive merger agreement with the board. Representatives of WSGR reviewed with the AATI directors their fiduciary duties in connection with considering the transaction and addressed questions of the board. After extensive discussion, the board directed management to continue negotiating the definitive merger agreement with Skyworks and, in particular, to focus on, among other issues, obtaining deal certainty and, given the historical price fluctuation of Skyworks common stock, certain price protections for the stockholders. The board also discussed potential compensation arrangements for certain directors and officers in connection with the merger, and the board received advice from an independent compensation consultant with respect to such matters. Subsequently, AATI disclosed these potential compensation arrangements to Skyworks.

On April 28, 2011, the board of directors of AATI held a regularly scheduled meeting at which Mr. Anderson and representatives of WSGR provided an update on the ongoing negotiations with Skyworks. In particular, representatives of WSGR elaborated on key structural issues presented by the proposed merger agreement, including the board’s ability to consider alternative transactions following the execution of the merger agreement, termination fees, price protection, closing conditions and the potentially taxable nature of the transaction to AATI stockholders as proposed. The board also reviewed an anticipated transaction schedule and received an updated analysis from its independent compensation consultant with respect to the potential compensation arrangements discussed at the prior board meeting.

On April 28, 2011, WSGR sent initial comments on the draft merger agreement to WilmerHale.

On April 29, 2011, Mr. Anderson communicated to Mr. Aldrich and Mr. Schiller that AATI’s board of directors had approved in principle the terms of the business deal they had discussed on April 18-19, subject to negotiation of a mutually acceptable definitive agreement.

On April 29, 2011, Mr. Aldrich sent Mr. Anderson an email indicating he would like to understand AATI’s second quarter revenue guidance. Mr. Anderson responded the same day by providing a draft earnings release (containing proposed second quarter guidance).

On May 2, 2011, AATI conducted its quarterly earnings call and estimated net revenue for the second calendar quarter of 2011 (ending June 30, 2011) in the range of $24.0 million to $26.0 million, net loss in the range of $0.04 to $0.02 per diluted share on a GAAP basis. On a non-GAAP basis, AATI estimated for the second calendar quarter of 2011 a range of net income of $0.01 to net loss of $0.01 per share. AATI also estimated pre-tax quarterly stock-based compensation expense of approximately $1.1 million.

On May 5, 2011, lead counsel from WilmerHale and WSGR discussed issues relating to the transaction, including timing, stockholder approval, next steps relating to the merger agreement and steps to expedite the completion of the due diligence process.

On May 9, 2011, WilmerHale sent a revised draft of the proposed form of merger agreement to WSGR.

On May 10, 2011, Mr. Aldrich and other senior executives of Skyworks met with Mr. Anderson, Mr. Williams and other senior executives of AATI in Woburn, Massachusetts to discuss, in detail, the status and outlook of AATI’s business.

On May 11, 2011, Skyworks’ board of directors received an update on the status of discussions between Skyworks and AATI.

On May 12, 2011, lead transaction counsel from WilmerHale and WSGR held an extended conference call to discuss key issues in the merger agreement, including issues relating to price and exchange ratio determination and adjustments, transaction structure, tax treatment of the transaction and AATI’s desire for reorganization treatment under the Internal Revenue Code so as to make the receipt of Skyworks stock nontaxable to AATI stockholders, deal protection (including the amount and triggers of the termination fee sought by Skyworks, details relating to the “no shop” clause proposed by Skyworks, the scope of AATI’s “fiduciary out” and ability to withdraw its recommendation of the transaction with Skyworks, and Skyworks’ request for a “force the vote” clause requiring AATI to bring the merger agreement to a vote of AATI stockholders even if AATI had received a superior proposal from another potential acquirer), the scope and details of closing conditions, the level of efforts the parties would be required to use to obtain regulatory and other approvals, the definition of a “material adverse effect,” and other points.

On May 15, 2011, WilmerHale sent a draft of a stockholder agreement (which would obligate AATI directors and officers to vote in favor of the merger and against any competing proposals that might arise, subject to AATI’s rights to terminate the merger agreement) to WSGR. That same day, WilmerHale also sent a draft of a noncompetition agreement (which would prohibit Mr. Williams from competing with the business of AATI for a period of time after the closing of the merger) to WSGR.

On May 16, 2011, Mr. Williams and certain AATI executives reviewed the consideration for the proposed transaction in light of AATI’s business forecast and benchmarked against stock performance of industry peers.

On May 16, 2011, WSGR provided WilmerHale with comments on the proposed form of stockholder agreement. Later that day, WilmerHale provided WSGR with a revised draft of the stockholder agreement accepting a majority of the changes requested by WSGR. Also on May 16, 2011, WSGR provided WilmerHale with an initial draft of a “disclosure schedule” responding (and setting forth exceptions) to AATI’s proposed representation and warranties is the draft merger agreement.

On May 18, 2011, the board of directors of AATI held a special telephonic meeting at which Mr. Anderson provided an update on the ongoing negotiations with Skyworks. Representatives of WSGR also reviewed the status of the definitive merger agreement and due diligence efforts and addressed questions of the board.

On May 19, 2011, WilmerHale sent a revised draft of the proposed form of merger agreement to WSGR, proposing compromises on many of the open issues, including, among other things, a reduction in the amount of the termination fee, narrower triggers for the termination fee, no “force the vote” clause, and modifications to the “no shop” provisions, closing conditions, “material adverse effect” definition, and other provisions.

On May 20, 2011, lawyers from WilmerHale and WSGR negotiated possible further changes to various provisions of the merger agreement, including in particular AATI’s representations and warranties.

On May 21, 2011, WSGR sent further comments on the draft merger agreement to Wilmer Hale. Mr. Schiller sent an e-mail to Mr. Anderson indicating that AATI’s comments on the merger agreement were problematic for Skyworks in a number of respects and raised questions as to whether the transaction would continue on schedule or if at all.

On May 23, 2011, Mr. Anderson and Mr. Schiller held a telephone discussion regarding AATI’s concerns with respect to price protection. In order to address these concerns, Skyworks proposed a mechanism that would ensure the value of the merger consideration at closing. Pursuant to this mechanism, the per share merger consideration would include an initial combination of $3.75 in cash and a fixed portion of a share of Skyworks common stock equal to $2.55 at the time of signing the merger agreement. The cash portion of the consideration would be increased or decreased to ensure that the total per share consideration would equal $6.30 at the time of closing, based upon the average closing price of Skyworks common stock over the five trading days immediately preceding the merger closing.

Also on May 23, 2011, lead transaction counsel from WilmerHale and WSGR held an extended conference call to negotiate possible compromises on the open issues in the merger agreement. WilmerHale then sent a revised draft of the merger agreement to WSGR early in the morning of May 24, 2011. Later in

the day on May 24, 2011, WilmerHale sent revised versions of the stockholder agreement and noncompetition agreement to WSGR.

Throughout the day on May 24 and May 25, 2011, WilmerHale and WSGR exchanged further comments on the draft merger agreement and the AATI disclosure schedule to the merger agreement, and continued to work toward finalizing the two documents.

On May 24, 2011, the board of directors of AATI held a special telephonic meeting at which representatives of WSGR reviewed the fiduciary duties of the board and presented a detailed summary of the draft definitive merger agreement and related ancillary agreements as well as open issues. The board also considered Skyworks’ proposal with respect to a price protection mechanism and found it to be a reasonable solution to AATI’s concerns. Representatives of Needham & Company also presented a preliminary financial analysis of the proposed transaction. Members of the board asked numerous questions and directed management and counsel to negotiate the open issues in the merger agreement in preparation for its expected execution the following day.

In the evening of May 24, 2011, WSGR informed WilmerHale that Mr. Williams, represented by separate legal counsel, would have a number of comments on the proposed form of noncompetition agreement that Skyworks required from him as a condition of signing the merger agreement with AATI. On May 25 and continuing into the morning of May 26, the parties and their counsel held a number of calls and exchanged proposed language in an effort to resolve the parties’ differences over the terms and language of the noncompetition agreement. These differences were finally resolved in the morning of May 26, 2011.

In the afternoon of May 25, 2011, the Skyworks board of directors held a special meeting to consider the proposed acquisition of AATI. After a review of the strengths and weaknesses of AATI’s business, the financial model for the acquisition, the parties’ negotiations, and the key terms and provisions of the merger agreement and related agreements, Skyworks’ board of directors expressed discomfort with the high premium that a price of $6.30 per share represented over recent trading prices of AATI’s common stock, and directed Skyworks management to seek an adjustment of the price, but otherwise unanimously approved the merger and related transactions and authorized senior management of Skyworks to finalize, execute and deliver the merger agreement on behalf of Skyworks, with such further changes as they might approve.

On May 25, 2011, the AATI board of directors held a special telephonic meeting. At this time, Mr. Anderson informed the board of directors that in a telephone discussion immediately preceding the board meeting, Mr. Schiller informed him that Skyworks was revising its offer to $6.13 per share. This price would be payable in a combination of $3.68 in cash and a fixed portion of a share of Skyworks common stock, but with the same price protection mechanism as previously agreed to with respect to the price of $6.30 per share. Representatives of Needham & Company and WSGR participated in the meeting and addressed questions of the board. The board instructed Mr. Anderson to continue discussions with Skyworks as to the business rationale for the price reduction, and the board adjourned the meeting until later that evening.

On May 25, 2011, during the time that the AATI board meeting was adjourned until later in the day, Mr. Anderson held a telephone conversation with Mr. Aldrich regarding the rationale for lowering the proposed price. Mr. Aldrich indicated that, ultimately, the Skyworks board of directors was uncomfortable with the high premium that a price of $6.30 per share represented over recent trading prices of AATI’s common stock. Members of the AATI board subsequently noted, for example, that the closing price of $3.61 per share on May 23, 2011 was one of the lowest closing prices over the preceding six-month period.

Later on May 25, 2011, the AATI board of directors reconvened its meeting. Mr. Anderson indicated that, in discussions following the earlier meeting of the board, Skyworks had informed him that it was unwilling to increase the acquisition price above $6.13 per share. The board held an extensive discussion regarding the strategic options and risks related to a further delay in the proposed transaction. Representatives of Needham & Company reviewed the financial terms presented in the proposed definitive merger agreement with the board. Representatives of WSGR reviewed with the directors of AATI their fiduciary duties in connection with considering the revised transaction terms and addressed questions of the board. After further discussion, the board directed Mr. Anderson to communicate to Skyworks that it was prepared to move forward with the

proposed transaction at the revised price of $6.13 per share only if the parties could finalize, execute and announce the merger agreement on the following day with no further material changes in price or other terms. Mr. Anderson excused himself from the meeting to communicate this message to Skyworks. He returned to the meeting with confirmation from Skyworks that it was prepared to abide by that schedule. However, Mr. Anderson indicated that Skyworks had informed him that it was requesting certain modifications to aspects of the compensation that the AATI board had contemplated awarding to each of Mr. Anderson and Mr. Williams in connection with the merger, which AATI previously had disclosed to Skyworks for its review and confirmation. In connection with Mr. Anderson’s extraordinary role in facilitating and negotiating the transaction with Skyworks, the AATI board had anticipated awarding Mr. Anderson 240,000 restricted stock units and a cash bonus of $950,000, which would vest or be payable, as applicable, upon the successful closing of the merger. The AATI board also had contemplated awarding Mr. Williams 60,000 restricted stock units in connection with his role in facilitating the transaction with Skyworks, which would vest upon the successful closing of the merger, as well as an additional 475,000 restricted stock units that would vest over a two-year period following the closing in connection with Mr. Williams entering into a two-year non-competition agreement with Skyworks. At this time, Skyworks requested that Mr. Anderson forego all of the contemplated cash bonus payment and that Mr. Williams forego 75,000 of the restricted stock units contemplated to be awarded in connection with the non-competition agreement. Mr. Anderson and Mr. Williams each indicated that they were willing to accept these compensation modifications requested by Skyworks. The board of directors adjourned the meeting until the following morning.

Later on the night of May 25, 2011, WilmerHale circulated a further revised draft of the merger agreement reflecting the new terms, and overnight on May 25-26 and during the day on May 26, 2011, WilmerHale and WSGR finalized the form of the merger agreement for final board approval and execution and delivery by the parties.

On May 26, 2011, the AATI board of directors held a telephonic meeting. Representatives of Needham & Company and WSGR participated in the meeting and addressed questions of the board. The board received a report on the status of the final definitive merger agreement and a review of the resolution of open issues. Representatives of Needham & Company presented a financial analysis and delivered its oral opinion to the AATI board of directors (subsequently confirmed in writing) to the effect that, as of May 26, 2011, and based upon and subject to the assumptions and other matters set forth in its written opinion, the consideration to be received by the holders of AATI common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders. The full text of the written opinion of Needham & Company is attached to this proxy statement/prospectus as Annex D. After extensive discussion and deliberations and taking into account the proposed terms of the merger agreement and the various presentations of its legal and financial advisors, including the factors described below under “AATI’s Reasons for the Merger; Recommendation of the AATI Board of Directors,” the AATI board unanimously adopted resolutions declaring the merger agreement and the transactions contemplated thereby to be advisable to and in the best interests of AATI and its stockholders and approved the merger agreement and the transactions contemplated thereby and authorized AATI to enter into the merger agreement with Skyworks. The board also approved the grant of restricted stock unit awards to certain directors and officers in connection with the merger as well as the additional restricted stock unit award to Mr. Williams in connection with his non-competition agreement with Skyworks.

On May 26, 2011, the parties executed the definitive merger agreement. In connection with entering into the merger agreement, Skyworks also entered into a stockholder agreement with certain of AATI’s officers and directors pursuant to which, among other things, each such officer and director agreed to vote all shares of AATI common stock beneficially owned by each such officer and director in favor of adoption of the merger agreement and approval of the merger and the other transactions contemplated by the merger agreement and against any other acquisition proposal or alternative acquisition agreement made in opposition to the consummation of the merger and the transactions contemplated by the merger agreement. Skyworks and Richard K. Williams also entered into a non-competition agreement pursuant to which, among other things, Mr. Williams agreed, for a period of 24 months following the closing of the merger and subject to certain exceptions, not to engage, without the express prior written consent of Skyworks, in any business or activity that is in competition with AATI’s business of developing, designing, manufacturing, licensing, marketing,

selling and distributing power management semiconductors and related software. Additionally, Mr. Williams agreed, for a period of 24 months following the closing of the merger, not to directly or indirectly solicit any individual then employed by either Skyworks or AATI to leave such employment or to solicit any AATI customers.

On May 26, 2011, following the closing of the Nasdaq Stock Market, the parties issued a press release announcing the execution of the merger agreement. Later that day, Mr. Aldrich and Mr. Williams held a joint investor conference call to review the proposed transaction.

AATI’s Reasons for the Merger; Recommendation of AATI’s Board of Directors

The AATI board of directors believes that the terms of the merger agreement and the merger and other transactions contemplated thereby are advisable, and in the best interests of, AATI and its stockholders. In reaching its decision to approve the merger, the AATI board of directors evaluated the merger in consultation with AATI’s management and advisors, and considered a number of factors, including, but not limited to, the following factors, which the AATI board of directors viewed as supporting its decision to approve the merger:


	•	Considerations Regarding Operating AATI as an Independent Company. The board considered the current and historical financial condition, results of operations, and anticipated future performance of AATI, as well as the risks and uncertainties associated with continuing to operate AATI as an independent company, including the following:


	•	the increasingly competitive nature of the power management semiconductor industry in which AATI competes and the need to increase the scale of AATI’s business and expand AATI’s potential customer base;

	•	the increasing ability of competitors to offer complete product portfolios and complex integrated solutions both organically funded by large R&D budgets and through substantial mergers and acquisitions;

	•	the trend of handset and large consumer OEMs buying from AATI to implement vendor reduction programs to improve operational efficiency, purchasing power, and pricing control over their supply chain;

	•	the ability of large semiconductor manufacturers competing with AATI to lower product cost and achieve higher margins through larger economies-of-scale and preferred pricing at foundries and manufacturing subcontractors;

	•	AATI’s slow pace in diversifying revenue into markets outside of handsets and handhelds, reflecting, in part, the lower volumes and longer design-in cycles of these markets, including televisions, clean technology, industrial and medical sectors;

	•	the potential impact of litigation on the operating cash flow of AATI and its adverse impact on AATI’s ability to adequately invest in new products and technology;

	•	AATI’s lack of revenue growth in recent periods and prospects for future growth;

	•	the need to increase the scale of AATI’s business and expand AATI’s potential customer base through acquisitions or other strategic transactions, the challenges of financing such acquisitions or other strategic transactions, and the potential execution risks and uncertainties associated therewith;

	•	the high cost of operating a public company, including legal and audit expenses and costs associated with Sarbanes-Oxley Act compliance; and

	•	the general risks associated with AATI’s ability to continue to execute its financial plan and create stockholder value in excess of the merger consideration being offered by Skyworks.


	•	Available Alternatives; Results of Discussions with Third Parties. The AATI board of directors considered the possible alternatives to the acquisition by Skyworks (including the possibility of being acquired by another company, continuing to operate AATI as an independent entity, or engaging in


		other strategic transactions, and the desirability and perceived risks of those alternatives), the range of potential benefits that these alternatives could bring to AATI’s stockholders and the timing and likelihood of accomplishing the goals of such alternatives, as well as the board’s assessment that none of these alternatives was reasonably likely to create greater value for AATI’s stockholders, taking into account risks of execution as well as business, management, competitive, industry and market risks. As part of its deliberations, the AATI board considered the results of the process that was conducted to evaluate alternative strategic transactions.


	•	Analysis and Presentation of Management. The analyses and presentations by senior management of AATI regarding the business, operations, sales, management and competitive position of AATI and forecasts regarding profitability under various scenarios.

	•	Strategic Considerations. The AATI board of directors considered their expectations that the merger would result in AATI becoming part of a larger, dynamic organization, better positioned to address customers’ demand for highly integrated power management solutions across a broader range of markets and applications than AATI would be able to on a stand-alone basis. The AATI board of directors considered the benefits resulting from the synergies of combining Skyworks’ existing leadership position in RF front-end solutions with AATI’s innovative application-specific power management solutions and by leveraging Skyworks’ scale and extensive product portfolio.

	•	Considerations Regarding Skyworks Common Stock. Given that a portion of the consideration to be received by AATI’s stockholders would consist of Skyworks common stock, the AATI board of directors considered the opportunity described in the preceding paragraph for AATI’s stockholders to participate as stockholders in the potential appreciation in the stock of Skyworks, in light of the perceived strategic benefits of AATI becoming part of a larger, yet dynamic, organization and the significant synergies that would be obtained by the merger.

	•	The Merger Consideration; Historical Trading Price. The AATI board of directors considered that the value of the merger consideration of $6.13 per share of AATI common stock, consisting initially of $3.68 in cash and 0.08725 of a share of Skyworks’ common stock, par value $0.25 per share, and subject to adjustment as set forth in the merger agreement, represented, based on the closing price of AATI’s common stock on May 25, 2011 of $3.84 (the last trading day prior to the approval of the merger by AATI’s board of directors), a 60% premium over the closing price per share of AATI common stock on May 25, 2011. Further, the AATI board of directors considered that the stock component of the merger consideration offers AATI’s stockholders the opportunity to participate in the growth and success of Skyworks for the reasons set forth above, while at the same time, the cash component of the merger consideration allows AATI’s stockholders to realize some liquidity and an immediate return on their investment in AATI common stock, and to cover their tax liability incurred in connection with the merger, if any.

	•	Financial Analysis and Opinion of Needham & Company. The AATI board of directors considered the financial analysis by Needham & Company, AATI’s financial advisor, of the proposed consideration and the opinion of Needham & Company, dated May 26, 2011, to the effect that, as of that date, and based upon and subject to the assumptions and other matters set forth in its opinion, the consideration to be received by holders of AATI common stock pursuant to the merger agreement was fair, from a financial point of view, to such holders. The full text of the written opinion of Needham & Company is attached to this proxy statement/prospectus as Annex D.

	•	Terms of the Merger Agreement. The AATI board of directors considered the terms and conditions of the merger agreement, including but not limited to the following:


	•	the belief that the terms of the merger agreement, including the parties’ mutual representations, warranties, covenants and closing conditions, are reasonable;

	•	AATI’s ability, under certain conditions, to provide information to and negotiate with a third party that has made an acquisition proposal that did not result from a breach of its non-solicitation obligations under the merger agreement if the AATI board determines in good faith (after


		consultation with its financial advisors and outside legal counsel) that the acquisition proposal is or is reasonably likely to lead to a superior proposal and if taking such action would be required by the AATI board’s fiduciary duties; and


	•	the ability of AATI’s board of directors, under certain circumstances, to make a change of recommendation and/or terminate the merger agreement in response to a bona fide acquisition proposal if (i) the AATI board reasonably determines in good faith (after consultation with its financial advisors and outside legal counsel) that such acquisition proposal is a superior proposal; (ii) the AATI board determines in good faith (after consultation with its outside legal counsel) that in light of such superior proposal, taking such action is required by the AATI board’s fiduciary duties; and (iii) AATI complies with certain procedures provided in the merger agreement.


	•	Risks and Potentially Negative Factors. During the course of its deliberations concerning the merger, the AATI board of directors and the management of AATI also identified and considered a variety of risks relating to the merger, including the following:


	•	the possibility that the merger might not be consummated, as a result of the failure to obtain required regulatory clearances to consummate the merger or the failure to obtain the requisite vote of the stockholders of AATI, and the potential adverse effects of the failure to consummate the merger on AATI’s business, customers, revenues, bookings, financial condition, operating results, employees and overall competitive positioning and prospects;

	•	the risk that as a result of the announcement of the merger, AATI’s existing relationships with customers could be significantly disrupted and AATI might have increased difficulty attracting new customers after such announcement;

	•	the risk that certain provisions of the merger agreement may have the effect of discouraging proposals for alternative acquisition transactions involving AATI, including the restriction on AATI’s ability to solicit proposals for alternative transactions and the requirement that AATI pay a termination fee of approximately $8.5 million to Skyworks or up to $500,000 in expense reimbursements to Skyworks in certain circumstances following the termination of the merger agreement;

	•	the risk that as a result of the announcement or the completion of the merger, key employees of AATI might terminate their employment with the company and the risk of the transaction diverting management’s attention from the day to day operation of AATI’s business during the pendency of the merger;

	•	the fees and expenses associated with completing or attempting to complete the merger;

	•	the potential impacts of the restrictions under the merger agreement on AATI’s ability to take certain actions during the period prior to the closing of the merger (which may delay or prevent AATI from undertaking business opportunities that may arise pending completion of the merger);

	•	the fact that certain of AATI’s directors and officers may have interests in the merger as individuals that are in addition to or different from the interests of AATI’s stockholders, as further described in the section entitled “Interests of AATI’s Directors and Executive Officers in the Merger” beginning on page [ • ] of this proxy statement/prospectus; and

	•	the other risks described in the section of this proxy statement/prospectus entitled “Risk Factors.”

This discussion of information and factors considered by the AATI board of directors is not intended to be exhaustive, but is intended to summarize the material factors considered by the AATI board of directors. In view of the wide variety of factors considered, the AATI board of directors did not find it practicable to quantify or otherwise assign relative weights to the specific factors considered. However, after taking into account all of the factors set forth above, the AATI board of directors unanimously agreed that the merger agreement and the transactions contemplated thereby were fair to, and in the best interests of, AATI and the AATI stockholders, and that AATI should enter into the merger agreement.

Opinion of AATI’s Financial Advisor

AATI retained Needham & Company to act as financial advisor in connection with the merger and to render an opinion as to the fairness, from a financial point of view, to the holders of AATI common stock of the consideration to be received by those holders pursuant to the merger agreement.

On May 26, 2011, Needham & Company delivered its oral opinion, which it subsequently confirmed in writing, to the AATI board of directors that, as of that date and based upon and subject to the assumptions and other matters described in the written opinion, the consideration to be received by the holders of AATI common stock pursuant to the merger agreement was fair to those holders from a financial point of view. Needham & Company provided its opinion for the information and assistance of the AATI board of directors in connection with and for the purpose of the board’s evaluation of the transactions contemplated by the merger agreement. Needham & Company’s opinion relates only to the fairness, from a financial point of view, to the holders of AATI common stock of the consideration, which was determined through arm’s length negotiations between AATI and Skyworks and not by Needham & Company. While Needham & Company provided independent financial advice to the AATI board of directors during the course of negotiations between AATI and Skyworks, the decision to approve and recommend the merger was made independently by the AATI board. Needham & Company’s opinion does not address any other aspect of the merger, or any related transaction, and does not constitute a recommendation to any stockholder of AATI as to how that stockholder should vote or act on any matter relating to the merger.

The complete text of Needham & Company’s opinion, which sets forth the assumptions made, procedures followed, matters considered, and qualifications and limitations on and scope of the review undertaken by Needham & Company, is attached to this proxy statement/prospectus as Annex D. The summary of Needham & Company’s opinion set forth below is qualified in its entirety by reference to the full text of the opinion. AATI stockholders should read this opinion carefully and in its entirety.

In arriving at its opinion, Needham & Company, among other things:


	•	reviewed the execution copy of the merger agreement;

	•	reviewed certain publicly available information concerning Skyworks and AATI and certain other relevant financial and operating data of Skyworks and AATI furnished to Needham & Company by Skyworks and AATI;

	•	reviewed the historical stock prices and trading volumes of Skyworks common stock and AATI common stock;

	•	held discussions with members of management of Skyworks and AATI concerning the current operations of and future business prospects for Skyworks and AATI and joint prospects for the combined companies;

	•	reviewed certain financial forecasts with respect to AATI prepared by management of AATI and held discussions with members of such management concerning those forecasts;

	•	reviewed certain research analyst projections with respect to Skyworks and held discussions with members of Skyworks management concerning those projections;

	•	compared certain publicly available financial data of companies whose securities are traded in the public markets and that Needham & Company deemed generally relevant to similar data for Skyworks and AATI;

	•	reviewed the financial terms of certain other business combinations that Needham & Company deemed generally relevant; and

	•	reviewed such other financial studies and analyses and considered such other matters as Needham & Company deemed appropriate.

In connection with its review and in arriving at its opinion, Needham & Company assumed and relied on the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by it for purposes of its opinion and did not independently verify, nor did Needham & Company assume responsibility for independent verification of, any of that information. Needham & Company assumed the accuracy of the representations and warranties contained in the merger agreement and all agreements related thereto. In addition, Needham & Company assumed that the merger will be consummated on the terms and subject to the conditions set forth in the execution copy of the merger agreement furnished to Needham & Company without waiver, modification or amendment of any material term, condition or agreement thereof and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Skyworks, AATI or the contemplated benefits of the merger. In addition, Needham & Company assumed that the financial forecasts for AATI provided to Needham & Company by AATI management were reasonably prepared on bases reflecting the best currently available estimates and judgments of management, at the time of preparation, of the future operating and financial performance of AATI, and that the research analyst projections for Skyworks represented reasonable estimates as to the future financial performance of Skyworks. Needham & Company expressed no opinion with respect to any of those forecasts, projections or estimates or the assumptions on which they were based.

Needham & Company did not assume any responsibility for or make or obtain any independent evaluation, appraisal or physical inspection of the assets or liabilities of Skyworks or AATI nor did Needham & Company evaluate the solvency or fair value of Skyworks or AATI under any state or federal laws relating to bankruptcy, insolvency or similar matters. Needham & Company’s opinion states that it was based on economic, monetary and market conditions as they existed and could be evaluated as of its date, and Needham & Company assumed no responsibility to update or revise its opinion based upon circumstances and events occurring after its date. Needham & Company’s opinion is limited to the fairness, from a financial point of view, to the holders of AATI common stock of the consideration to be received by those holders pursuant to the merger agreement and Needham & Company expressed no opinion as to the fairness of the merger to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of AATI, or as to AATI’s underlying business decision to engage in the merger or the relative merits of the merger as compared to other business strategies that might be available to AATI. Needham & Company was not requested to and did not solicit any expressions of interest from any other parties with respect to the sale of all or any part of AATI or any alternative transaction. In addition, Needham & Company expressed no opinion with respect to the amount or nature or any other aspect of any compensation payable to or to be received by any officers, directors or employees of any party to the merger, or any class of those persons, relative to the consideration to be received by the holders of AATI common stock pursuant to the merger agreement or with respect to the fairness of any such compensation. Needham & Company did not express any opinion as to what the value of Skyworks common stock will be when issued pursuant to the merger or the prices at which Skyworks common stock or AATI common stock will actually trade at any time.

AATI imposed no limitations on Needham & Company with respect to the investigations made or procedures followed by Needham & Company in rendering its opinion.

In preparing its opinion, Needham & Company performed a variety of financial and comparative analyses. The following paragraphs summarize the material financial analyses performed by Needham & Company in arriving at its opinion. The order of analyses described does not represent relative importance or weight given to those analyses by Needham & Company. Some of the summaries of the financial analyses include information presented in tabular format. The tables are not intended to stand alone, and in order to more fully understand the financial analyses used by Needham & Company, the tables must be read together with the full text of each summary. The following quantitative information, to the extent it is based on market data, is, except as otherwise indicated, based on market data as it existed on or prior to May 26, 2011, and is not necessarily indicative of current or future market conditions.

Selected Companies Analysis. Using publicly available information, Needham & Company compared selected historical and projected financial and market data ratios for AATI to the corresponding data and ratios

of publicly traded companies that Needham & Company deemed relevant because they have lines of businesses that may be considered similar to AATI’s lines of business. These companies, referred to as the selected companies, consisted of the following:

Cirrus Logic, Inc.
Micrel, Incorporated
Monolithic Power Systems, Inc.
O2Micro International Limited
Power Integrations, Inc.
Semtech Corporation
Supertex, Inc.
Volterra Semiconductor Corporation

The following table sets forth information concerning the following multiples for the selected companies and for AATI:


	•	enterprise value as a multiple of last 12 months, or LTM, revenues;

	•	enterprise value as a multiple of projected calendar year 2011 revenues;

	•	enterprise value as a multiple of projected calendar year 2012 revenues;

	•	enterprise value as a multiple of projected calendar year 2011 earnings before interest, taxes, depreciation, amortization, and stock compensation expense, or adjusted EBITDA;

	•	enterprise value as a multiple of projected calendar year 2012 adjusted EBITDA;

	•	price as a multiple of projected calendar year 2011 earnings per share, or EPS;

	•	price as a multiple of projected calendar year 2012 EPS; and

	•	price as a multiple of book value.

Needham & Company also reviewed, for the selected companies, enterprise value as a multiple of LTM adjusted EBITDA and price as a multiple of LTM EPS, but determined that the results were not meaningful because of AATI’s negative LTM adjusted EBITDA and EPS.

Needham & Company calculated multiples for the selected companies based on the closing stock prices of those companies on May 25, 2011 and for AATI based on a total merger consideration value of $6.13 per share.

Premiums Paid Analysis. Needham & Company analyzed publicly available financial information for 37 merger and acquisition transactions, which represent transactions announced and closed between January 1, 2009 and May 25, 2011 that involved equity values below $1 billion and acquired companies that were publicly-traded technology companies. Of these transactions, three involved all stock consideration, seven involved a combination of cash and stock consideration, and 27 involved all cash consideration. In reviewing

these transactions, Needham & Company analyzed the premium of consideration offered to the acquired company’s stock price one day, seven days, 30 days and 60 days prior to the announcement of the transaction.

Needham & Company calculated premiums for AATI based on a total merger consideration value of $6.13 per share. The following table sets forth information concerning the stock price premiums in the selected transactions and the stock price premiums implied by the merger.

Contribution Analysis. Needham & Company reviewed and analyzed the implied percentage contribution of each of Skyworks and AATI to pro forma combined operating results for the last reported 12 months, and pro forma projected calendar year 2011 and calendar year 2012 combined operating results. In calculating the pro forma projected combined operating results, Needham & Company used estimates provided by AATI management and consensus research analyst projections for Skyworks. Needham & Company reviewed, among other things, the implied percentage contributions to pro forma combined revenues, gross profit, adjusted EBITDA and EBIT. The following tables present the results of this analysis and the estimated pro forma enterprise value contributions of Skyworks and AATI, based on a total merger consideration value of $6.13 per share. In calculating pro forma enterprise value contributions, Needham & Company assumed that outstanding options to purchase AATI common stock would remain outstanding and used the treasury stock method to calculate the number of pro forma shares of Skyworks common stock outstanding.

The results of the contribution analysis are not necessarily indicative of the contributions that the respective businesses may have in the future.

No company, transaction or business used in the “Selected Companies Analysis,” “Premiums Paid Analysis” or “Selected Transactions Analysis” as a comparison is identical to Skyworks, AATI or the merger. Accordingly, an evaluation of the results of these analyses is not entirely mathematical; rather, it involves complex considerations and judgments concerning differences in the financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the selected companies or selected transactions or the business segment, company or transaction to which they are being compared.

The summary set forth above does not purport to be a complete description of the analyses performed by Needham & Company in connection with the rendering of its opinion. The preparation of a fairness opinion is a complex analytical process involving various determinations as to the most appropriate and relevant quantitative and qualitative methods of financial analyses and the application of those methods to the particular circumstances and, therefore, such an opinion is not readily susceptible to summary description. Accordingly, Needham & Company believes that its analyses must be considered as a whole and that selecting portions of its analyses or

the factors it considered, without considering all analyses and factors, could create a misleading or incomplete view of the process underlying its analyses and opinion. Needham & Company did not attribute any specific weight to any factor or analysis considered by it. The fact that any specific analysis has been referred to in the summary above is not meant to indicate that such analysis was given greater weight than any other analysis.

In performing its analyses, Needham & Company made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond Skyworks’ or AATI’s control. Any estimates contained in or underlying these analyses, including estimates of AATI’s future performance, are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those estimates. Additionally, analyses relating to the values of businesses or assets do not purport to be appraisals or necessarily reflect the prices at which businesses or assets may actually be sold or the prices at which any securities have traded or may trade at any time in the future. Accordingly, these analyses and estimates are inherently subject to substantial uncertainty. Needham & Company’s opinion and its related analyses were only one of many factors considered by AATI’s board of directors in their evaluation of the merger and should not be viewed as determinative of the views of AATI’s board of directors or management with respect to the consideration or the merger.

Under the terms of its engagement letter with Needham & Company, AATI has paid or agreed to pay Needham & Company a retainer fee and a fee for rendering the Needham & Company opinion aggregating $1,050,000. If the merger is consummated, AATI has agreed to pay Needham & Company an additional fee of 1.0% of the aggregate purchase price paid in the merger, against which the retainer fee and the fee for rendering the Needham & Company opinion would be credited. In addition, AATI has agreed to reimburse Needham & Company for its out-of-pocket expenses in connection with its engagement and to indemnify Needham & Company and related persons against various liabilities, including certain liabilities under the federal securities laws.

Needham & Company is a nationally recognized investment banking firm. As part of its investment banking services, Needham & Company is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of securities, private placements and other purposes. Needham & Company was retained by the AATI board of directors to act as its financial advisor based on Needham & Company’s experience as a financial advisor in mergers and acquisitions as well as Needham & Company’s familiarity with AATI and its industry generally. Needham & Company has not had any other investment banking relationship with Skyworks or AATI during the past two years for which it received compensation. Needham & Company may in the future provide investment banking and financial advisory services to Skyworks, AATI or their respective affiliates unrelated to the merger, for which services Needham & Company would expect to receive compensation. In the normal course of its business, Needham & Company may actively trade the equity securities of Skyworks and AATI for its own account or for the account of its customers and, therefore, may at any time hold a long or short position in those securities.

Financial Forecasts

As a matter of course, neither AATI nor Skyworks make public projections as to future sales, earnings, or other results due to, among other reasons, the uncertainty inherent in underlying assumptions and estimates. However, during the course of negotiations, AATI management prepared certain financial forecasts that it shared with Skyworks management in April 2011. These forecasts, which were prepared on a stand-alone, pre-merger basis, took into account recent cost-containment efforts of AATI management, as well as recent market activity. AATI further revised its forecasts in May 2011 to address additional information available to AATI management and provided the updated financial forecasts to Needham & Company, which are summarized below. The accompanying prospective financial information included in this proxy statement/prospectus was not prepared with a view toward public disclosure or with a view toward complying with the guidelines established by the American Institute of Certified Public Accountants with respect to prospective financial information, but, in the view of AATI’s management, was prepared on a reasonable basis, reflects the best currently available estimates and judgments, and presents, to the best of management’s knowledge and belief, the expected course of action and the expected future financial performance of AATI. However, this information is not fact and should not be relied upon as being necessarily indicative of future results, and readers of this proxy statement/prospectus are cautioned not to place undue reliance on the prospective information.

Neither AATI’s nor Skyworks’ independent auditors nor any other independent accountants, have reviewed, compiled, examined or performed any procedures with respect to the prospective financial information contained herein, nor have they expressed any opinion or any other form of assurance on such information or its achievability, and assume no responsibility for, and disclaim any association with, the prospective financial information.

Furthermore, the financial forecasts summarized below in this proxy statement/prospectus:


	•	while presented with numerical specificity, necessarily reflect numerous estimates and assumptions made with respect to industry performance and competition, general business, economic, market and financial conditions and matters specific to AATI’s business, all of which are difficult to predict and many of which are beyond their respective control;

	•	include assumptions as to certain business decisions that are subject to change;

	•	may be affected by the ability of AATI to achieve strategic goals, objectives and targets over the applicable period;

	•	do not necessarily reflect revised prospects for AATI’s business, changes in general business or economic conditions or any other transactions or events that have occurred subsequent to, or that may occur and that were not anticipated at, the time the forecasts were prepared;

	•	are not necessarily indicative of actual current or future performance, which may be significantly more favorable or less favorable than as set forth below; and

	•	should not be regarded by their inclusion in this proxy statement/prospectus as a representation that the financial forecasts can or will be achieved by AATI, whether or not the merger occurs.

THE FINANCIAL FORECASTS SET FORTH BELOW WERE PREPARED IN THE COURSE OF DUE DILIGENCE AND DO NOT REFLECT REVISED PROSPECTS FOR AATI’S BUSINESS OR OTHER DEVELOPMENTS SINCE THE DATE THE FORECASTS WERE PREPARED. THE FINANCIAL FORECASTS ARE NOT NECESSARILY INDICATIVE OF ACTUAL CURRENT OR FUTURE PERFORMANCE, ARE NOT A GUARANTEE OF FUTURE PERFORMANCE AND ARE NOT GUIDANCE.

In addition, AATI stockholders are urged to review the section entitled “Risk Factors” beginning on page [ • ] of this proxy statement/prospectus as well as those risk factors described in Item 1A of AATI’s Form 10-Q for the quarter ended March 31, 2011, filed with the SEC on May 3, 2011, and in Item 1A of AATI’s Form 10-K for the year ended December 31, 2010, filed with the SEC on February 25, 2011, as amended by Amendment No. 1 thereto filed with the SEC on May 2, 2011.

Skyworks’ Reasons for the Merger

The Skyworks board of directors believes that the terms of the merger agreement and the merger and other transactions contemplated thereby are advisable, and in the best interests of, Skyworks and its stockholders, and the directors present at the May 25, 2011 meeting of the Skyworks board of directors, constituting a quorum for the transaction of business, unanimously approved the merger agreement and the merger. Skyworks’ board of directors believes that the acquisition of AATI presents a compelling strategic opportunity for Skyworks, will be complementary to the Skyworks’ business and will help Skyworks to capitalize on its strong smart phone, tablet, set-top box and infrastructure positions with an expanded and differentiated product portfolio while accelerating its entry into new vertical markets. At a higher level, Skyworks believes that analog power management semiconductors represent a strategic growth market for Skyworks, as Skyworks’ customers increasingly demand both ubiquitous wireless connectivity and power optimization across seemingly every kind of electronic platform. With AATI, Skyworks believes that it will be well positioned to address these twin market opportunities, leveraging the companies’ customer relationships, innovative product portfolios and increasing operational scale.

Merger Sub’s board of directors, acting by unanimous written consent, approved the merger agreement and the merger and other transactions contemplated thereby.

In reaching its decision to approve the merger, the Skyworks board of directors evaluated the merger in consultation with Skyworks’ management and advisors, and considered a number of factors, including, but not limited to, the following factors, which the Skyworks board of directors viewed as supporting its decision to approve the merger:


	•	entry of Skyworks into the power management market;


	•	the anticipated enhanced competitive positioning of the combined company, which, as a result of the merger, will have a broader range of products and technologies to offer to customers;

	•	the belief that AATI’s business is complementary to the Skyworks business;

	•	the belief that the merger will increase Skyworks’ revenues and be accretive to Skyworks’ non-GAAP earnings;

	•	the results of Skyworks’ due diligence review of AATI’s business, finances, operations, assets and technology and Skyworks’ evaluation of AATI’s management, organization, competitive position and prospects;

	•	the financial, business, legal, contractual and other terms and conditions of the merger agreement, including the provisions regarding the ability of the AATI board of directors to entertain third-party acquisition proposals as described under “The Merger Agreement — No Solicitation,” “— Change in Recommendation by AATI’s Board,” “— Termination of the Merger Agreement” and “— Transaction Fees and Expenses; Termination Fee;”

	•	the amount of cash and cash equivalents held by AATI and expected to be held at the time of the merger, together with the amount of cash and cash equivalents held by Skyworks and expected to be held at the time of the merger; and

	•	the likelihood that the regulatory approvals needed to complete the transaction will be obtained without undue delay and without imposing any conditions on the combined company.

During the course of its deliberations concerning the merger, the Skyworks board of directors and the management of Skyworks also identified and considered a variety of risks relating to the merger, including the following:


	•	the risk that the potential benefits and synergies sought in the merger might not be realized;

	•	the challenges, costs and diversion of management time associated with successfully integrating the products, technologies, marketing strategies, cultures and organizations of each company, while also integrating another recent acquisition;

	•	the risk of management and employee disruption associated with the merger;

	•	the risk that certain key employees of AATI may leave AATI before the merger is completed or may not remain employed by Skyworks after the completion of the merger;

	•	the risk that Skyworks may not be able to achieve the projected growth of the AATI business over the long term;

	•	the risk that the combined company and its products may not be able to compete against competitors;

	•	risks arising from or related to intellectual property issues;

	•	the risk that a third party could make a superior proposal to acquire AATI and the provisions of the merger agreement that give AATI the right to respond to certain unsolicited proposals and that allow the AATI board of directors to change its recommendation that AATI’s stockholders approve and adopt the merger agreement or to terminate the merger agreement;

	•	the possibility that the merger may not be completed;

	•	the premium that the implied merger consideration represents over the trading price of AATI’s common stock, which was approximately 60% at the close of trading on Nasdaq on May 25, 2011, the last trading day before the day on which the merger agreement was signed;

	•	the need to obtain AATI stockholder and regulatory approvals to complete the transaction; and

	•	the other risks described in the section of this proxy statement/prospectus entitled “Risk Factors.”

This discussion of information and factors considered by the Skyworks board of directors is not intended to be exhaustive, but is intended to summarize the material factors considered by the Skyworks board of directors. In view of the wide variety of factors considered, the Skyworks board of directors did not find it practicable to quantify or otherwise assign relative weights to the specific factors considered. However, after taking into account all of the factors set forth above, the directors present at the meeting of the Skyworks board of directors at which the merger agreement and the merger were considered unanimously agreed that the merger agreement and the merger and other transactions contemplated thereby were advisable and fair to, and in the best interests of, Skyworks and the Skyworks stockholders, and that Skyworks should enter into the merger agreement.

Interests of AATI’s Directors and Executive Officers in the Merger

In considering the recommendation of the AATI board of directors to adopt the merger agreement and approve the merger, you should be aware that AATI’s directors and executive officers have interests in the merger that are different from, or in addition to, their interests as AATI stockholders. The AATI board of directors was aware of and considered these interests, among other matters, in reaching its decision to approve, adopt and declare advisable the merger agreement, the merger and the other transactions contemplated by the merger agreement. These interests include:


	•	the possible employment of certain of AATI’s executive officers by Skyworks after the merger, although no agreements have been proposed or entered into;

	•	the potential vesting of all unvested AATI option and restricted stock awards outstanding under AATI’s 2005 Equity Incentive Plan and 1998 Stock Plan, as described under “The Merger Agreement — Treatment of Stock Options, Restricted Stock Units and Employee Stock Purchase Plan;”

	•	the potential vesting of some or all unvested AATI options and restricted stock units held by AATI’s executive officers, as described under “— Severance and Change of Control Provisions;”

	•	the potential receipt of severance benefits in connection with a termination of employment in connection with the merger, as described under “— Severance and Change of Control Provisions;” and

	•	the receipt of indemnification and liability insurance benefits by directors and executive officers of AATI from Skyworks, as described under “— Indemnification of Directors and Executive Officers.”

All of AATI’s executive officers are parties to change in control agreements with AATI, each of which provides severance and other benefits if the executive’s employment is terminated in connection with a change in control of AATI, including the consummation of the merger. Under certain circumstances, the termination of employment will result in, among other things, acceleration of vesting of some or all unvested equity awards granted to AATI’s officers. Executive officers and directors of AATI have rights to indemnification, advancement of expenses and directors’ and officers’ liability insurance that will survive consummation of the merger.

On May 26, 2011, AATI’s board of directors also approved an additional grant of 400,000 restricted stock units to Richard K. Williams, AATI’s president, chief executive officer and chief technical officer, as consideration for entering into the non-competition agreement with Skyworks as a condition to the merger. Such restricted stock units shall vest, if at all, monthly over a 2-year period commencing with the date of the closing of the merger.

Treatment of Stock Options

Certain of AATI’s directors and executive officers hold AATI options. Each of their options will be assumed and converted into an option to purchase Skyworks common stock as described below under “The Merger Agreement — Treatment of Stock Options, Restricted Stock Units and Employee Stock Purchase Plan.” The table below indicates the aggregate number of vested and unvested AATI options held by AATI’s directors and executive officers as of July 29, 2011 that will be assumed and converted into options to purchase Skyworks common stock as a result of the merger (assuming the merger was consummated on such date and vested options were not otherwise exercised prior to such date) and the number of unvested AATI options held by AATI’s directors and executive officers as of July 29, 2011 that will accelerate vesting and become fully vested as a result of the merger (assuming the merger was consummated on such date):

The table below also indicates the number of unvested AATI RSUs held by AATI’s directors and executive officers that will accelerate vesting and become fully vested as a result of the merger (assuming the merger was consummated on such date and vested RSUs were not otherwise settled in cash or AATI common stock prior to such date):

Severance and Change of Control Provisions

In September 1998, AATI entered into an employment offer letter with Mr. Richard K. Williams, its president, chief executive officer and chief technical officer. Pursuant to his employment offer letter, if Mr. Williams’ employment is terminated without cause, he will be entitled to continue to receive payment of his base salary and insurance benefits for two weeks following the date of termination, as well as any accrued and unpaid bonus amounts.

In May 2005, AATI’s board of directors authorized a form of change of control agreement for each of AATI’s current and future officers of a level of vice president and above. The change of control agreement provides that in the event the employee is terminated without cause, or is constructively terminated, within 12 months of a change of control, including the consummation of the merger, 100% of all unvested stock rights as of such date shall become fully vested on the termination date with respect to AATI’s chief executive officer and chief financial officer and 50% of all unvested stock rights as of such date shall become fully vested on the termination date with respect to AATI’s other officers of a level of vice president and above. In this event, the employee will also receive continued salary and benefits for 12 months following the termination date. For purposes of this agreement, “stock rights” means all options or rights to acquire shares of AATI’s common stock and includes all options granted under AATI’s 1998 Stock Plan and the 2005 Equity Incentive Plan. Each of AATI’s current officers of a level of vice president and above has entered into a change of control agreement with these terms.

In February 2009, AATI’s board of directors authorized amendments to AATI’s executive officer change of control agreements which provide for the payment of all or a portion of the officer’s target bonus amount for the applicable year in the event that a severance payment is due to the officer. The amended change of control agreements provide that in the event that a severance payment is triggered, the chief executive officer and chief financial officer would be entitled to 100% of their target bonus for the fiscal year in which such change of control transaction occurs, including the consummation of the merger, and other officers of a level

of vice president and above would be entitled to 50% of their target bonus for the fiscal year in which such change of control transaction occurs, including the consummation of the merger.

The following tables show the potential payments and benefits that each of AATI’s named executive officers could receive pursuant to the terms of such named executive officer’s change of control agreement. For purposes of these tables, it is assumed that the merger is consummated on July 29, 2011 and each named executive officer’s employment terminated at the close of business on July 29, 2011. The value of accelerated stock options is calculated by multiplying the number of unvested shares subject to acceleration by the difference between the exercise price and the merger consideration of $6.13 per share. Due to the number of factors that affect the nature and amount of any potential payments or benefits, any actual payments and benefits may be different.

Indemnification of Directors and Executive Officers

AATI’s amended and restated certificate of incorporation and bylaws contain provisions limiting the liability of directors to the fullest extent authorized and permitted by the Delaware General Corporation Law. In addition, AATI has entered into separate indemnification agreements with each of its directors and executive officers to the fullest extent permitted under Delaware law.

For six years after the effective time of the merger, Skyworks has agreed to cause the surviving corporation in the merger to honor all of AATI’s obligations to indemnify and hold harmless each present and former director and officer of AATI against any costs or expenses (including attorneys’ fees), judgments, fines, losses, claims, damages, liabilities or amounts paid in settlement incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to matters existing or occurring at or prior to the merger, whether asserted or claimed before, at or after the effective time of the merger, to the extent that such obligations to indemnify and hold harmless exist on May 26, 2011.

For six years after the effective time of the merger, Skyworks has also agreed to cause the surviving corporation to maintain in effect (to the extent available in the market) a directors’ and officers’ liability insurance policy covering those persons who are currently covered by AATI’s directors’ and officers’ liability insurance policy with coverage in amount and scope at least as favorable to such persons as AATI’s existing coverage. In no event will Skyworks or the surviving corporation be required to expend in excess of 250% of the annual premium currently paid by AATI for such coverage. If the annual premium exceeds that amount, Skyworks will cause the surviving corporation to obtain as much coverage as practicable for such amount. The obligation to maintain D&O insurance may be satisfied by either Skyworks or AATI purchasing a “tail” policy under AATI’s directors’ and officers’ liability insurance policy in effect immediately before the effective time of the merger.

Material U.S. Federal Income Tax Consequences of the Merger

The following discussion sets forth the material U.S. federal income tax consequences of the merger to U.S. holders (as defined below) that exchange their AATI common stock for Skyworks common stock and cash in the merger. This discussion is based upon the Internal Revenue Code, the U.S. Treasury regulations promulgated under the Internal Revenue Code and court and administrative rulings and decisions, all as in effect on the date of this proxy statement/prospectus. These laws may change, possibly retroactively, and any change could affect the accuracy of the statements and conclusions set forth in this discussion. This discussion does not address any tax consequences arising under the laws of any state, local or foreign jurisdiction, or under any U.S. federal laws other than those pertaining to income tax.

For purposes of this discussion, the term “U.S. holder” means a beneficial owner of shares of AATI common stock that is, for U.S. federal income tax purposes:


	•	an individual who is a citizen or resident of the United States;

	•	a corporation (including any entity treated as a corporation for U.S. federal income tax purposes) created or organized under the laws of the United States, any state thereof or the District of Columbia;

	•	a trust if (i) a U.S. court is able to exercise primary supervision over the trust’s administration and one or more U.S. persons are authorized to control all substantial decisions of the trust or (ii) it has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person; or

	•	an estate the income of which is subject to U.S. federal income tax regardless of its source.

If a partnership (including any entity treated as a partnership for U.S. federal income tax purposes) holds shares of AATI common stock, the tax treatment of a partner in such partnership will generally depend on the status of the partner and the activities of the partnership. If you are a partner of a partnership holding shares of AATI common stock, you should consult your tax advisor.

This discussion assumes that a holder holds its shares of AATI common stock as a capital asset within the meaning of Section 1221 of the Internal Revenue Code (generally, property held for investment). This discussion does not address all aspects of U.S. federal income taxation that might be relevant to holders in light of their particular circumstances, or to holders that may be subject to special rules (including, for example, dealers in securities or currencies, traders in securities that elect mark-to-market treatment, financial institutions, insurance companies, mutual funds, tax-exempt organizations, holders liable for the alternative minimum tax, partnerships or other flow-through entities and their partners or members, U.S. expatriates, non-U.S. holders, holders whose functional currency is not the U.S. dollar, holders who hold AATI common stock as part of a hedge, straddle, constructive sale or conversion transaction or other integrated investment and holders who acquired AATI common stock pursuant to the exercise of employee stock options or otherwise as compensation (including holders of AATI restricted stock)).

This discussion of the material U.S. federal income tax consequences of the merger to U.S. holders that exchange their AATI common stock for Skyworks common stock and cash in the merger is for general information only and is not tax advice. The determination of the actual tax consequences of the merger to a holder of AATI common stock will depend on the holder’s specific situation. Holders of AATI common stock

should consult their own tax advisors as to the tax consequences of the merger in their particular circumstances, including the applicability and effect of the alternative minimum tax and any state, local, foreign or other tax laws and of changes in those laws.

Consequences of the Merger Generally. The receipt of Skyworks common stock and cash in exchange for AATI common stock in the merger will be a taxable transaction for U.S. federal income tax purposes. A U.S. holder who receives Skyworks common stock and cash in the merger will recognize capital gain or loss equal to the difference, if any, between (1) the sum of the fair market value of Skyworks common stock as of the effective time of the merger and the amount of cash received, including any cash received in lieu of fractional shares of Skyworks common stock, received in the merger, and (2) such holder’s adjusted tax basis in its AATI common stock exchanged therefor. Any capital gain or loss will be long-term capital gain or loss if the U.S. holder’s holding period for its AATI common stock is more than one year at the time of the merger. Currently, long-term capital gain for non-corporate taxpayers is taxed at a maximum federal income tax rate of 15%. If the U.S. holder has held its AATI common stock for one year or less at the time of the merger, any capital gain or loss will be short-term capital gain or loss. The deductibility of capital losses is subject to certain limitations. If a U.S. holder acquired different blocks of AATI common stock at different times or different prices, such U.S. holder must determine its tax basis and holding period separately with respect to each block of AATI common stock.

A U.S. holder’s aggregate tax basis in its Skyworks common stock received in the merger will equal the fair market value of such stock at the time of the merger, and the U.S. holder’s holding period for such stock will begin on the day after the merger.

Information Reporting and Backup Withholding. Payments of cash and shares of Skyworks common stock made to a U.S. holder may, under certain circumstances, be subject to information reporting and backup withholding at the applicable rate (currently 28%), unless such U.S. holder properly establishes an exemption or provides a correct taxpayer identification number, and otherwise complies with the backup withholding rules. Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be refunded or credited against a U.S. holder’s U.S. federal income tax liability, provided the required information is timely furnished to the Internal Revenue Service.

THE FOREGOING SUMMARY IS NOT INTENDED TO BE A COMPLETE ANALYSIS OF POTENTIAL TAX CONSIDERATIONS RELATING TO THE MERGER, AND IS NOT TAX ADVICE. THEREFORE, HOLDERS OF AATI COMMON STOCK ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES RESULTING FROM THE MERGER, INCLUDING THE APPLICABILITY OF FEDERAL, STATE, LOCAL, NON-U.S. AND OTHER TAX LAWS.

Regulatory Approvals

AATI and Skyworks have agreed to cooperate with each other and to use their commercially reasonable efforts to make filings and to obtain approvals required for the completion of the merger. The transactions contemplated by the merger agreement are not subject to a waiting period or filings under the HSR Act, but do require a filing and are subject to review in the Republic of Korea. Even though the transactions contemplated by the merger agreement are not subject to the HSR Act, at any time before or after the merger is completed, either the FTC or the DOJ, or any other antitrust authority having jurisdiction over AATI and Skyworks, could take action under applicable antitrust laws in opposition to the merger, including seeking to enjoin the transaction or seeking divestiture of substantial assets of AATI, Skyworks or their subsidiaries. Private parties also may seek to take legal action under antitrust laws under some circumstances.

AATI and Skyworks are not aware of any material governmental or regulatory approvals or actions that are required for completion of the merger other than as described above. It is presently contemplated that if any such additional material governmental approvals or actions are required, those approvals or actions will be sought. There can be no assurance, however, that any additional approvals or actions will be obtained.

Board of Directors and Executive Officers of Skyworks Following the Merger

Upon completion of the merger, the Skyworks board of directors is expected to continue to be composed of nine members, consisting of the nine members of the Skyworks board of directors immediately prior to the completion of the merger. Each executive officer of Skyworks immediately prior to the completion of the merger is expected to continue as an executive of Skyworks upon completion of the merger.

Litigation Related to the Merger

On June 6, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202403) naming AATI, the members of AATI’s board of directors, Skyworks and Merger Sub as defendants. The complaint alleges, among other things, (a) that the members of the AATI’s board of directors breached their fiduciary duties by (i) failing to take steps to maximize the value of the merger consideration to AATI’s stockholders, (ii) taking steps to avoid competitive bidding, and (iii) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, and (b) that AATI, the members of AATI’s board of directors, Skyworks and Merger Sub aided and abetted these purported breaches of fiduciary duties. The complaint seeks to enjoin consummation of the merger or, if the merger is completed, to recover damages caused by the alleged breaches of fiduciary duties. The complaint also seeks recovery of attorney’s fees and costs of the lawsuit.

On June 7, 2011, a putative stockholder class action lawsuit was filed in California Superior Court in Santa Clara County (Case No. 111CV202501) naming AATI, the members of AATI’s board of directors, Skyworks and Merger Sub as defendants. The complaint alleges, among other things, (a) that the members of AATI’s board of directors breached their fiduciary duties by (i) agreeing to the merger for inadequate consideration on unfair terms, (ii) failing to protect against conflicts of interest resulting from change-of-control and transaction-related benefits received by AATI directors in connection with the merger that are not available to all stockholders, (iii) selling the company in response to alleged pressure from Dialectic Capital Partners, LP, and (iv) taking steps to avoid competitive bidding (including the entry by certain AATI officers and directors into agreements with Skyworks relating to voting commitments and inclusion in the merger agreement of nonsolicitation provisions and a termination fee), and (b) that AATI, the members of AATI’s board of directors, Skyworks and Merger Sub aided and abetted these purported breaches of fiduciary duties. The complaint seeks to enjoin consummation of the merger, and to have the court direct the defendants to implement procedures and processes to maximize shareholder value. The complaint also seeks recovery of attorney’s fees and costs of the lawsuit.

AATI, AATI’s board of directors and Skyworks believe that the claims in both of these actions are without merit and intend to defend against such claims vigorously.

Dividend Policy

Skyworks and AATI stockholders have historically not received dividends. The payment of dividends by Skyworks after the merger will be subject to the determination of the Skyworks board of directors. Decisions by the Skyworks board of directors regarding whether or not to pay dividends on Skyworks common stock and the amount of any dividends will be based on compliance with the DGCL, compliance with agreements governing Skyworks’ indebtedness, earnings, cash requirements, results of operations, cash flows and financial condition and other factors that the Skyworks board of directors considers important. Skyworks has not paid a dividend on its common stock since its incorporation. While Skyworks anticipates that if the merger were consummated it would continue not to pay dividends, Skyworks can make no assurances that this will be the case in the future.

AATI Stockholders’ Rights of Appraisal

If the merger is consummated, dissenting holders of AATI common stock who follow the procedures specified in Section 262 within the appropriate time periods will be entitled to have their shares of AATI common stock appraised by the Court of Chancery, and to receive the “fair value” of such shares in cash as

determined by the Court of Chancery, together with a fair rate of interest, if any, to be paid on the amount determined to be the fair value, in lieu of the merger consideration that such stockholder would otherwise be entitled to receive pursuant to the merger agreement. The fair value of AATI common stock as determined by the Court of Chancery may be more or less than, or the same as, the merger consideration that you are otherwise entitled to receive under the terms of the merger agreement.

This section provides a brief summary of Section 262, which sets forth the procedures for dissenting from the merger and demanding and perfecting appraisal rights. Failure to follow the procedures set forth in Section 262 precisely will result in the loss of appraisal rights. This summary is not a complete statement regarding the appraisal rights of AATI stockholders or the procedures that they must follow in order to seek and perfect appraisal rights under Delaware law and is qualified in its entirety by reference to the text of Section 262, a copy of which is attached to this proxy statement/prospectus as Annex E. The following summary does not constitute any legal or other advice, nor does it constitute a recommendation that AATI stockholders exercise appraisal rights under Section 262.

IF YOU WISH TO EXERCISE APPRAISAL RIGHTS OR WISH TO PRESERVE YOUR RIGHT TO DO SO, YOU SHOULD REVIEW ANNEX E CAREFULLY AND SHOULD CONSULT YOUR LEGAL ADVISOR, AS FAILURE TO TIMELY COMPLY WITH THE PROCEDURES SET FORTH IN ANNEX E WILL RESULT IN THE LOSS OF YOUR APPRAISAL RIGHTS.

Under Section 262, where a merger is to be submitted for adoption at a meeting of stockholders, such as the AATI special meeting, not less than 20 days prior to the meeting a constituent corporation, such as AATI, must notify each of its stockholders for whom appraisal rights are available that such appraisal rights are available and include in each such notice a copy of Section 262. This proxy statement/prospectus constitutes such notice to holders of AATI common stock concerning the availability of appraisal rights under Section 262. Appraisal rights are not available to holders of Skyworks common stock.

AATI stockholders wishing to assert appraisal rights must hold the shares of AATI common stock on the date of making the written demand for appraisal rights with respect to such shares and must continuously hold such shares through the effective time. AATI stockholders who desire to exercise appraisal rights must also satisfy all of the conditions of Section 262. A written demand for appraisal of shares must be delivered to AATI before the vote on the merger occurs. This written demand for appraisal of shares must be in addition to and separate from a vote against the proposal to adopt the merger agreement, or an abstention or failure to vote for the proposal to adopt the merger agreement. AATI stockholders electing to exercise their appraisal rights must not vote FOR the adoption of the merger agreement. A vote against the adoption of the merger agreement will not constitute a demand for appraisal within the meaning of Section 262. A proxy that is submitted and does not contain voting instructions will, unless revoked, be voted in favor of the proposal to adopt the merger agreement, and it will constitute a waiver of the stockholder’s right of appraisal and will nullify any previously delivered written demand for appraisal. Therefore, an AATI stockholder who submits a proxy and who wishes to exercise appraisal rights must either submit a proxy containing instructions to vote against the proposal to adopt the merger agreement or abstain from voting on the proposal to adopt the merger agreement.

To be effective, a demand for appraisal by an AATI stockholder must be made by, or in the name of, the stockholder of record, fully and correctly, as the stockholder’s name appears on the stockholder’s stock certificate(s) or in the transfer agent’s records, in the case of uncertificated shares.

The demand cannot be made by the beneficial owner if he or she does not also hold the shares of AATI common stock of record. The beneficial holder must, in such cases, have the registered owner, such as a bank, brokerage firm or other nominee, submit the required demand in respect of those shares of AATI common stock. If you hold your shares of AATI common stock through a bank, brokerage firm or other nominee and you wish to exercise appraisal rights, you should consult with your bank, brokerage firm or the other nominee to determine the appropriate procedures for the making of a demand for appraisal by the nominee.

If shares of AATI common stock are owned of record in a fiduciary capacity, such as by a trustee, guardian or custodian, execution of a demand for appraisal should be made in that capacity. If the shares of

AATI common stock are owned of record by more than one person, as in a joint tenancy or tenancy in common, the demand should be executed by or for all joint owners. An authorized agent, including an authorized agent for two or more joint owners, may execute the demand for appraisal for a stockholder of record; however, the agent must identify the record owner or owners and expressly disclose the fact that, in executing the demand, he or she is acting as agent for the record owner. A record owner, such as a bank, brokerage firm or other nominee, who holds shares of AATI common stock as a nominee for others, may exercise his or her right of appraisal with respect to the shares of AATI common stock held for one or more beneficial owners, while not exercising this right for other beneficial owners. In that case, the written demand should state the number of shares of AATI common stock as to which appraisal is sought. Where no number of shares of AATI common stock is expressly mentioned, the demand will be presumed to cover all shares of AATI common stock held in the name of the record owner.

All demands for appraisal should be addressed to AATI, 3230 Scott Blvd., Santa Clara, California 95054, Attention: Corporate Secretary. The demand must reasonably inform AATI of the identity of the AATI stockholder as well as the stockholder’s intention to demand an appraisal of the “fair value” of the shares held by the stockholder. A stockholder’s failure to make the written demand prior to the taking of the vote on the adoption of the merger agreement at the special meeting will constitute a waiver of appraisal rights.

Within 10 days after the effective time, AATI must provide notice of the effective time to all of its stockholders who have complied with Section 262 and have not voted FOR the adoption of the merger agreement. At any time within 60 days after the effective time, any AATI stockholder who has not commenced an appraisal proceeding or joined an appraisal proceeding as a named party will have the right to withdraw his, her or its demand for appraisal and to accept the merger consideration specified in the merger agreement. After this period, an AATI stockholder may withdraw his, her or its demand for appraisal and receive payment for his, her or its shares as provided in the merger agreement only with the consent of the surviving corporation. Unless the demand is properly withdrawn by the AATI stockholder within 60 days after the effective time, no appraisal proceeding in the Court of Chancery will be dismissed as to any AATI stockholder without the approval of the Court of Chancery, with such approval conditioned upon such terms as the Court of Chancery deems just. If the surviving corporation does not approve a request to withdraw a demand for appraisal when that approval is required, or if the Court of Chancery does not approve the dismissal of an appraisal proceeding, the AATI stockholder will be entitled to receive only the appraised value determined in any such appraisal proceeding, which value could be less than, equal to or more than the consideration offered pursuant to the merger agreement.

Within 120 days after the effective time (but not thereafter), either the surviving corporation or any AATI stockholder who has complied with the requirements of Section 262 and who is otherwise entitled to appraisal rights may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the fair value of the shares of AATI common stock owned by stockholders entitled to appraisal rights. The surviving corporation has no obligation to file such a petition if demand for appraisal is made, and holders should not assume that it will file a petition. If no petition for appraisal is filed with the Court of Chancery within 120 days after the effective time, stockholders’ rights to appraisal (if available) will cease.

Accordingly, it is the obligation of the holders of AATI common stock to initiate all necessary action to perfect their appraisal rights in respect of shares of AATI common stock within the time prescribed in Section 262.

Within 120 days after the effective time, any AATI stockholder who has complied with Section 262 will be entitled, upon written request, to receive from the surviving corporation a statement listing the aggregate number of shares not voted in favor of the merger and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. The statement must be mailed within 10 days after a written request therefore has been received by the surviving corporation. A person who is the beneficial owner of shares of AATI common stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition for appraisal or request from the surviving corporation the statement described in this paragraph.

Upon the filing of any petition by an AATI stockholder in accordance with Section 262, service of a copy must be made upon the surviving corporation. The surviving corporation must, within 20 days after service, file in the office of the Delaware Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares of AATI common stock and with whom AATI has not reached agreements as to the value of their shares. The Court of Chancery may require the stockholders who have demanded an appraisal for their shares (and who hold stock represented by certificates) to submit their stock certificates to the Register in Chancery for notation of the pendency of the appraisal proceedings and the Court of Chancery may dismiss the proceedings as to any stockholder that fails to comply with such direction.

After notice to the stockholders as required by the Court of Chancery, the Court of Chancery is empowered to conduct a hearing on the petition to determine those stockholders who have complied with Section 262 and who have become entitled to appraisal rights thereunder. After the Court of Chancery determines the holders of AATI common stock entitled to appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding, the Court of Chancery shall determine the “fair value” of shares of AATI common stock as of the effective time, after taking into account all relevant factors, exclusive of any element of value arising from the accomplishment or expectation of the merger, together with a fair rate of interest, if any, to be paid upon the amount determined to be the fair value. Unless the Court of Chancery in its discretion determines otherwise for good cause shown, interest from the effective time through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective time and the date of payment of the judgment.

AATI stockholders considering seeking appraisal of their shares should note that the fair value of their shares determined under Section 262 could be more or less than, or equal to, the consideration they would receive pursuant to the merger agreement if they did not seek appraisal of their shares of AATI common stock. Stockholders should be aware that an investment banking opinion as to fairness from a financial point of view is not necessarily an opinion as to fair value under Section 262. Although AATI believes that the merger consideration is fair, no representation is made as to the outcome of the appraisal of fair value as determined by the Court of Chancery. Moreover, AATI does not anticipate offering more than the merger consideration to any stockholder exercising appraisal rights and reserves the right to assert, in any appraisal proceeding, that, for purposes of Section 262, the “fair value” of a share of AATI common stock is less than the merger consideration. In determining “fair value,” the Court of Chancery is required to take into account all relevant factors. In Weinberger v. UOP, Inc., the Delaware Supreme Court discussed the factors that could be considered in determining fair value in an appraisal proceeding, stating that “proof of value by any techniques or methods which are generally considered acceptable in the financial community and otherwise admissible in court” should be considered and that “fair price obviously requires consideration of all relevant factors involving the value of a company.” The Delaware Supreme Court has stated that in making this determination of fair value the court must consider market value, asset value, dividends, earnings prospects, the nature of the enterprise and any other facts which could be ascertained as of the date of the merger which throw any light on future prospects of the merged corporation. Section 262 provides that fair value is to be “exclusive of any element of value arising from the accomplishment or expectation of the merger.” In Cede & Co. v. Technicolor, Inc., the Delaware Supreme Court stated that such exclusion is a “narrow exclusion [that] does not encompass known elements of value,” but which rather applies only to the speculative elements of value arising from such accomplishment or expectation. In Weinberger, the Delaware Supreme Court construed Section 262 to mean that “elements of future value, including the nature of the enterprise, which are known or susceptible of proof as of the date of the merger and not the product of speculation, may be considered.”

The costs of the appraisal proceeding (which do not include attorneys’ fees or the fees and expenses of experts) may be determined by the Court of Chancery and taxed against the parties as the Court of Chancery deems equitable under the circumstances. Upon application of a dissenting stockholder, the Court of Chancery may order all or a portion of the expenses incurred by any dissenting stockholder in connection with the appraisal proceeding, including reasonable attorneys’ fees and the fees and expenses of experts, to be charged

pro rata against the value of all shares entitled to appraisal. In the absence of a contrary determination, each party bears his, her or its own expenses.

Any AATI stockholder who has demanded appraisal will not, after the effective time, be entitled to vote for any purpose the shares of AATI common stock subject to demand or to receive payment of dividends or other distributions on such shares, except for dividends or distributions payable to stockholders of record at a date prior to the effective time.

Failure by any AATI stockholder to comply fully with the procedures of Section 262 of the DGCL (as reproduced in Annex E to this proxy statement/prospectus) may result in termination of such stockholder’s appraisal rights and the stockholder will be entitled to receive the merger consideration (without interest) for his, her or its shares of AATI common stock pursuant to the merger agreement.

THE PROCESS OF DISSENTING REQUIRES STRICT COMPLIANCE WITH TECHNICAL PREREQUISITES. THOSE INDIVIDUALS OR ENTITIES WISHING TO DISSENT AND TO EXERCISE THEIR APPRAISAL RIGHTS SHOULD CONSULT WITH THEIR OWN LEGAL COUNSEL IN CONNECTION WITH COMPLIANCE UNDER SECTION 262 OF THE DGCL. TO THE EXTENT THERE ARE ANY INCONSISTENCIES BETWEEN THE FOREGOING SUMMARY AND SECTION 262 OF THE DGCL, THE DGCL WILL CONTROL.

Source of Funds for Cash Consideration

The merger is not conditioned upon any other financing arrangements or contingencies. Based upon Skyworks’ current cash on hand and the cash anticipated to be generated by its business operations, Skyworks anticipates that as of the closing of the merger it will have sufficient cash on hand to pay the cash consideration contemplated by the merger agreement.

Merger Expenses, Fees and Costs

Other than as described in “The Merger Agreement — Transaction Fees and Expenses; Termination Fee” and in connection with a termination of the merger agreement, fees and expenses incurred in connection with the merger agreement and the merger will be paid by the party incurring those fees and expenses, whether or not the merger is consummated. See “The Merger Agreement — Transaction Fees and Expenses; Termination Fee.”

Restrictions on Resales by Affiliates

The shares of Skyworks common stock to be issued in connection with the merger will be freely transferable under the Securities Act, except for shares issued to any stockholder who may be deemed to be an “affiliate” of Skyworks for purposes of Rule 144 under the Securities Act. Persons who may be deemed to be affiliates include individuals or entities that control, are controlled by, or are under common control with, Skyworks and may include the executive officers, directors and significant stockholders of Skyworks.

Stock Exchange Listing of Skyworks Common Stock

Skyworks will use its reasonable best efforts to cause the shares of Skyworks common stock issuable pursuant to the merger agreement to be approved for listing on The Nasdaq Global Select Market at or prior to the effective time of the merger, subject to official notice of issuance. Approval of the listing on The Nasdaq Global Select Market of the shares of Skyworks common stock issuable to AATI stockholders in the merger, subject to official notice of issuance, is a condition to each party’s obligation to complete the merger.

Delisting and Deregistration of AATI Common Stock

If the merger is completed, AATI’s common stock will be delisted from and will no longer be traded on Nasdaq and will be deregistered under the Exchange Act. Following the completion of the merger, AATI will no longer be an independent public company.

Accounting Treatment

The merger will be accounted for under the acquisition method of accounting, in conformity with GAAP. Under the acquisition method of accounting, the assets (including identifiable intangible assets) and liabilities (including executory contracts and other commitments) of AATI as of the effective time will be recorded at their respective fair values and added to those of Skyworks. Any excess of purchase price over the fair value of the net assets is recorded as goodwill. Financial statements of Skyworks issued after the merger would reflect these fair values and would not be restated retroactively to reflect the historical financial position or results of operations of AATI.

THE MERGER AGREEMENT

The summary of the material provisions of the merger agreement below and elsewhere in this proxy statement/prospectus is qualified in its entirety by reference to the merger agreement, a copy of which is attached to this proxy statement/prospectus as Annex A and which AATI and Skyworks incorporate by reference into this proxy statement/prospectus. This summary does not purport to be complete and may not contain all of the information about the merger agreement that is important to you. AATI and Skyworks encourage you to read carefully the merger agreement in its entirety.

The merger agreement is described in this proxy statement/prospectus and included as Annex A only to provide you with information regarding its terms and condition, and not to provide any other factual information regarding AATI or Skyworks or their respective businesses. Such information can be found elsewhere in this document and in the public filings that AATI and Skyworks make with the SEC, which are available without charge through the SEC’s website at www.sec.gov.

The merger agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about AATI or Skyworks. In particular, the assertions embodied in the representations and warranties contained in the merger agreement and described below are qualified by information in a confidential “disclosure schedule” provided by AATI to Skyworks in connection with the signing of the merger agreement. This confidential disclosure schedule contains information that modifies, qualifies and creates exceptions to the representations and warranties set forth in the merger agreement. Moreover, the representations and warranties in the merger agreement may have been used for the purpose of allocating risk between AATI and Skyworks rather than for the purpose of establishing matters as facts. Accordingly, you should not rely on the representations and warranties in the merger agreement as characterizations of the actual state of facts about AATI or Skyworks.

In addition, the merger agreement is dated as of May 26, 2011 and the representations and warranties included in the merger agreement and described below speak as of that date (the date of the merger agreement) or other specific dates. The status of matters covered by the representations and warranties in the merger agreement may change after May 26, 2011 and after other specified dates, and these changes may or may not be fully reflected in public disclosures by Skyworks or AATI. The assertions embodied in those representations and warranties may also be subject to important qualifications and limitations agreed to by AATI and Skyworks in connection with negotiating the terms of that agreement, including a contractual standard of materiality that may be different from what stockholders may view as material, and a contractual standard of knowledge that may not reflect the knowledge that a stockholder might expect or desire. Accordingly, investors should not rely on the representations and warranties or the covenants in the merger agreement as characterizations of the actual state of facts about Skyworks or AATI.

The Merger

The merger agreement provides that, subject to the terms and conditions of the merger agreement, and in accordance with the Delaware General Corporation Law, at the effective time of the merger, Merger Sub will be merged with and into AATI and, as a result of the merger, the separate corporate existence of Merger Sub will cease and AATI will continue as the surviving corporation and become a wholly owned subsidiary of Skyworks.

Effective Time of the Merger; Closing

The merger will become effective as of the date and time specified in the certificate of merger filed by AATI with the Secretary of State of the State of Delaware or such other date and time agreed to by Skyworks and AATI. The filing of the certificate of merger will occur on the closing date of the merger or as soon as practicable thereafter. The closing date will be on a date specified by AATI and Skyworks, which will be no later than the second business day after satisfaction or waiver of the conditions to the closing of the merger set forth in the merger agreement and described in this proxy statement/prospectus.

At the effective time of the merger, the certificate of incorporation and bylaws of the surviving corporation will be amended and restated so that they are identical to the certificate of incorporation and bylaws of Merger Sub (except as to the name of the surviving corporation and other ministerial details).

Directors and Officers

The merger agreement provides that Merger Sub’s directors and officers immediately prior to the effective time of the merger will be the initial directors and officers of the surviving corporation.

The Merger Consideration

Upon completion of the merger, each outstanding share of AATI common stock (except for shares held directly or indirectly by Skyworks, Merger Sub, AATI or any wholly owned subsidiary of AATI, and except for shares of AATI common stock held by stockholders exercising dissenter’s rights) will automatically become the right to receive an aggregate of $6.13 per share, payable in the form of 0.08725 of a share of Skyworks common stock (the “stock consideration”) and an adjustable cash amount in the initial calculated amount of $3.68 (the “cash consideration” and, together with the stock consideration, the “merger consideration”), without interest and less applicable withholding taxes. The amount of stock was based on the average last sale price of Skyworks common stock (at the 4 p.m. Eastern Time end of Nasdaq regular trading hours) over the 30-trading days prior to May 26, 2011. At that average price, the stock consideration had a nominal value of $2.45 and the nominal aggregate combined value of the cash consideration and the stock consideration was $6.13. The final cash consideration will depend on the closing value of the stock consideration, calculated on the basis of Skyworks’ average reported last sale price in regular Nasdaq trading during a five-trading-day measurement period preceding the closing of the merger. If the closing value of the stock consideration is less than $2.45, the cash consideration will increase by the amount of the shortfall. If the closing value of the stock consideration is more than $2.45, the cash consideration will decrease by the amount of the excess. And if the closing value of the stock consideration is exactly $2.45, the cash consideration will remain unchanged at $3.68. In each case, the merger consideration will maintain a constant nominal aggregate combined value of $6.13 per share of AATI common stock.

No fractional shares of Skyworks will be issued in connection with the merger. Instead, an AATI stockholder who otherwise would have received a fraction of a share of Skyworks common stock will receive an amount in cash rather than a fractional share. This cash amount will be determined by multiplying the fraction of a share of Skyworks common stock that the holder would otherwise receive by the average of the last reported sales prices of Skyworks Common Stock at the 4 p.m. (Eastern Time) end of regular trading hours on Nasdaq during the ten (10) consecutive trading days ending on the last trading day prior to the effective time of the merger.

No assurance can be given (and it is not likely) that the market price of Skyworks common stock on the date that stock is received by an AATI stockholder or at any other time, will be the same as the market price of Skyworks common stock as of May 25, 2011, the last full trading day before the date of the merger agreement, as of the date of this proxy statement/prospectus or as of the date of the special meeting of AATI’s stockholders called to consider the merger.

Payment and Exchange Procedures

Prior to the effective time of the merger, Skyworks will designate its transfer agent, American Stock Transfer & Trust Company, LLC, or another bank and trust company reasonably acceptable to AATI, to act as exchange agent for the merger. As of the effective time of the merger, Skyworks will deposit with the exchange agent (1) cash in an amount sufficient to pay the aggregate cash consideration (including cash for fractional shares) described in “— The Merger Consideration” above and (2) certificates representing the

shares of Skyworks common stock to be issued in the merger. In addition, Skyworks will make available to the exchange agent any dividends or distributions then payable to holders as described in “— Dividends and Distributions” below.

If you hold stock certificates representing shares of AATI common stock that are outstanding immediately prior to the effective time of the merger, then, as soon as reasonably practicable after the effective time, the exchange agent will mail you (i) a form letter of transmittal and (ii) instructions for use in effecting the surrender of AATI stock certificates. The letter of transmittal will specify that delivery will be effected, and risk of loss and title to AATI common stock certificates will pass, only upon proper delivery of such certificates (and any other documents that the exchange agent may reasonably require) to the exchange agent, and will contain other customary provisions as Skyworks and AATI may agree. You should not submit your AATI stock certificates for exchange until you receive the transmittal instructions and a form of letter of transmittal from the exchange agent. Upon surrender of such AATI common stock certificates for cancellation together with such letter of transmittal duly executed and completed and other documents reasonably requested by the exchange agent, you will be entitled to receive (A) a check or wire transfer (at the election of Skyworks or the exchange agent) for the amount of cash consideration to which you are entitled pursuant to the merger agreement, (B) a certificate for the number of whole shares of Skyworks common stock to which you are entitled pursuant to the merger agreement, (C) any dividends or other distributions then payable (as described in “— Dividends and Distributions” below) and (D) any cash in lieu of fractional shares of Skyworks common stock (as described in “— The Merger Consideration” above), and the certificates of AATI common stock you surrendered will be canceled.

In the event of a transfer of ownership of AATI common stock that is not registered in AATI’s transfer agent’s records, payment of the merger consideration as described above will be made to a person other than the person named in the certificate as the registered holder only if (A) the certificate is properly endorsed or otherwise is in proper form for transfer and (B) the person requesting the exchange pays any transfer or other taxes required by reason of the payment of the merger consideration to such other person.

Following the effective time of the merger, there will be no further transfers of shares of AATI common stock.

Any amounts required to be deducted and withheld under federal, state, local or foreign tax law will be deducted and withheld from the consideration otherwise payable to you under the merger agreement.

If a certificate for AATI common stock has been lost, stolen or destroyed, the exchange agent will issue the consideration properly payable under the merger agreement upon receipt of an affidavit, in form and substance reasonably acceptable to Merger Sub, of that fact by the person claiming such certificate to be lost, stolen or destroyed. The posting of a bond in an amount reasonably acceptable to Merger Sub as indemnity may also be required.

One hundred eighty days after the effective time of the merger, the exchange agent will deliver to the surviving corporation all cash and shares of Skyworks common stock remaining in the exchange fund administered by the exchange agent that have not been distributed to holders of AATI shares. Thereafter, AATI stockholders must look only to the surviving corporation for payment of the merger consideration, any unpaid dividends and any cash in lieu of fractional shares of Skyworks common stock payable pursuant to the merger agreement.

Dividends and Distributions

If you hold your shares of AATI common stock in certificated form and are entitled to receive the merger consideration with respect to such shares, until you have surrendered your share certificates, a duly completed letter of transmittal and other documents as described in “— Payment and Exchange Procedures” above, any dividends or other distributions declared after the effective time of the merger with respect to Skyworks common stock into which shares of AATI common stock may have been converted will accrue but will not be paid with respect to your shares. After the surrender of the certificates representing AATI common stock, a duly completed letter of transmittal and other documents as described in “— Payment and Exchange

Procedures” above, you will be entitled to be paid, without interest, (A) the amount of any dividends or other distributions with a record date after the effective time of the merger previously accrued and paid with respect to whole shares of Skyworks common stock you own, and (B) at the appropriate payment date, any additional dividends or other distributions with a record date after the effective time of the merger but before surrender and a payment date after surrender that are then payable with respect to the whole shares of Skyworks common stock you own. There can be no assurance that any dividends will be declared or paid by Skyworks following the effective time of the merger, or as to the amount or timing of such dividends, if any. Any future dividends will be made at the discretion of the Skyworks board of directors. Historically, neither Skyworks nor AATI has paid dividends.

Treatment of Stock Options, Restricted Stock Units and Employee Stock Purchase Plan

Stock Options

At the effective time of the merger, each AATI option will be assumed and converted into an option to purchase Skyworks common stock, on the same terms and conditions as were applicable under such AATI option as of immediately prior to the effective time of the merger, but taking into account any acceleration thereof provided for in the related AATI plan document, award document or any other agreement. The number of shares of Skyworks common stock subject to each assumed AATI option will be equal to the number of shares of AATI common stock subject to the assumed AATI option immediately prior to the effective time of the merger, multiplied by the option conversion ratio, rounded down, if necessary, to the nearest whole share of Skyworks common stock. The assumed option will have an exercise price per share (rounded up to the nearest whole cent) equal to the exercise price per share of AATI common stock divided by the option conversion ratio. The “option conversion ratio” is defined as $6.13 divided by the average last reported sale price of Skyworks common stock (at the 4 p.m. Eastern Time end of Nasdaq regular trading hours) on the five full trading days ending on the trading day immediately prior to the date on which the effective time of the merger occurs.

Restricted Stock Units

Each outstanding award of AATI restricted stock units (“RSUs”) that is to be settled in AATI common stock will be assumed by Skyworks and will be converted into restricted stock units to acquire that number of shares of Skyworks common stock equal to the product obtained by multiplying (x) the number of shares of AATI common stock subject to such RSU and (y) the option conversion ratio, rounded down to the nearest whole share of Skyworks common stock. Each assumed RSU will otherwise be subject to the same terms and conditions (including as to vesting) as were applicable to the RSUs immediately prior to the effective time of the merger.

Employee Stock Purchase Plan

No further shares of AATI common stock will be issued to participants under AATI’s Employee Stock Purchase Plan, as amended (the “ESPP”). There is no offering period in progress, and AATI has covenanted in the merger agreement that no new offering period will begin. The ESPP will be terminated as of or prior to the effective time of the merger.

Material Adverse Effect

Some of the parties’ representations and warranties, and some of the conditions to the closing of the merger, refer to the absence of a “Material Adverse Effect” or exclude matters that do not or would not be expected or likely to have a “Material Adverse Effect.” This term is defined in detail in the merger agreement, and has two substantially parallel versions, one that applies to Skyworks (“Buyer Material Adverse Effect”) and one that applies to AATI (“Company Material Adverse Effect”).

As a general matter, a “Company Material Adverse Effect” is any event, change, circumstance or effect that, either individually or in the aggregate, and taken together with all other effects, has (or have) a material adverse effect on the business, assets, liabilities, condition (financial or otherwise), operations or results of operations of AATI and its subsidiaries, taking AATI together with its subsidiaries as a whole. This basic definition is subject to a number of exclusions and interpretive rules.

Under the exclusions, no effect (either by itself or when aggregated or taken together with any and all other such effects) proximately caused by any of the matters described in the following clauses shall be deemed to be or to constitute a “Company Material Adverse Effect” and no such effect shall be taken into account when determining whether a “Company Material Adverse Effect” has occurred or may occur:


	•	general economic conditions in the United States, China or any other country (or changes therein), general conditions in the financial markets in the United States, China or any other country (or changes therein), or general political conditions in the United States, China or any other country (or changes therein), in any such case to the extent that such conditions or changes do not affect AATI and its subsidiaries in a disproportionate manner relative to other participants in the industries in which AATI and its subsidiaries conduct business;

	•	general conditions in the industries in which AATI and its subsidiaries conduct business (or changes therein) to the extent that such conditions or changes do not affect AATI and its subsidiaries in a disproportionate manner relative to other participants in the industries in which AATI and its subsidiaries conduct business;

	•	general conditions caused by acts of terrorism, war or armed hostilities to the extent that such acts of terrorism, war or armed hostilities do not affect AATI or any of its subsidiaries directly or in a disproportionate manner relative to other participants in the industries in which AATI and its subsidiaries conduct business;

	•	changes (in and of themselves) in the trading price or volume of AATI’s stock (it being understood, acknowledged and agreed that the underlying causes of, and the facts, circumstances or occurrences giving rise or contributing to such changes may be deemed to constitute a “Company Material Adverse


		Effect” (unless otherwise excluded by this definition) and may be taken into account in determining whether there has been, is, or would be a Company Material Adverse Effect); or


	•	failure (in and of itself) by AATI to meet any internal or public projections, forecasts or estimates of revenues or earnings (it being understood, acknowledged and agreed that the underlying causes of, and the facts, circumstances or occurrences giving rise or contributing to such failure, and any legal liabilities resulting from such failure, may be deemed to constitute a “Company Material Adverse Effect” (unless otherwise excluded by this definition) and may be taken into account in determining whether there has been, is, or would, could or is likely to be a Company Material Adverse Effect).

In addition, the merger agreement provides that no effect (either by itself or when aggregated or taken together with any and all other such effects) resulting directly and primarily from any of the matters described in the following clauses shall be deemed to be or to constitute a “Company Material Adverse Effect” and no such effect shall be taken into account when determining whether a “Company Material Adverse Effect” has occurred or may occur:


	•	the response of customers, suppliers, distributors, business partners and employees of AATI and its subsidiaries to the announcement of the merger agreement and the pendency of the transactions contemplated hereby;

	•	action taken by AATI or its subsidiaries at the express written request of Skyworks after the date of the merger agreement (May 26, 2011) (and in conformity therewith) that is not required by the terms of the merger agreement; and

	•	changes in GAAP (or the interpretation thereof) that affect the consolidated financial statements of AATI and its subsidiaries.

The merger agreement also contains a number of interpretive rules for the interpretation of the term “Company Material Adverse Effect”. These interpretive rules clarify that:


	•	With respect to the assets and/or liabilities of AATI and its subsidiaries, an effect that would otherwise constitute a Company Material Adverse Effect (or would otherwise be considered in determining whether a Company Material Adverse Effect has occurred or would, could or is likely to occur) shall constitute a Company Material Adverse Effect (and shall be considered in determining whether a Company Material Adverse Effect has occurred or would, could or is likely to occur) even if such effect is a one-time or non-recurring and whether or not the impact of such effect is permanent, ongoing, long-term or short-term.

	•	The term “business” includes (but is not limited to) the long-term future earnings potential of AATI and its subsidiaries.

	•	The terms “material”, “materially” or “materiality” as used in the merger agreement with an initial lower case “m” shall have their respective customary and ordinary meanings, without regard to the special meanings ascribed to the term “Company Material Adverse Effect”.

	•	When a statement in a representation and warranty by AATI is qualified by the phrase “in all material respects,” materiality shall be determined solely by reference to, and solely within the context of, the particular representation and warranty in which such qualifying phrase is used and not with respect to the entirety of the merger agreement or the entirety of the transactions contemplated by the merger agreement.

	•	To the extent possible, unless provisions are mutually exclusive and effect cannot be given to both or all such provisions, (A) the representations and warranties, covenants, agreements and closing conditions in the merger agreement shall be construed to be cumulative, (B) each representation and warranty, covenant, agreement and closing condition in the merger agreement shall be given full separate and independent effect, and (C) no limitation in or exception to any representation and warranty, covenant, agreement or closing condition shall be construed to limit or apply to any other representation and warranty, covenant, agreement or closing condition unless such limitation or


		exception is expressly made applicable to such other representation and warranty, covenant, agreement or closing condition.

Covenants Regarding Conduct of Business by AATI Prior to the Merger

In the merger agreement, AATI has agreed that before the effective time of the merger, subject to certain exceptions, AATI (and will cause each of its subsidiaries to) act and carry on its business in the usual, regular and ordinary course in substantially the same manner as previously conducted, pay its debts and taxes and perform its other obligations prior to delinquency (subject to good faith disputes), comply with all applicable laws, rules and regulations, and use commercially reasonable best efforts, consistent with past practices, to maintain and preserve its and each of its subsidiaries’ business organization, assets and properties, keep available the services of its present officers and employees and preserve its advantageous business relationships with customers, strategic partners, suppliers, distributors and others having business dealings with it to the end that its goodwill and ongoing business shall be unimpaired at the effective time of the merger.

No Solicitation

Notwithstanding the restrictions described above, if AATI stockholders have not yet adopted the merger agreement, AATI may take certain otherwise prohibited actions in response to an unsolicited proposal from a third party that constitutes (or that the AATI board of directors determines in good faith, after consultation with outside legal counsel and its independent financial advisor, is reasonably likely to lead to) a superior proposal, to the extent that the fiduciary obligations of the AATI board of directors require (as determined in good faith by AATI’s board of directors after consulting with outside counsel). The proposal cannot be the result of a breach by AATI of the no-shop restrictions. If the conditions for this exception apply, the merger agreement permits AATI to furnish information (but only pursuant to a customary confidentiality agreement that is not less restrictive of the third party than AATI’s confidentiality agreement with Skyworks) and it also permits AATI to participate in discussions or negotiations (including solicitation of a revised proposal) with the third party and its representatives regarding the proposal.

To qualify as a superior proposal, the proposal must be an unsolicited, bona fide written proposal from a third party to acquire more than 50% of the equity securities or assets of AATI and its subsidiaries, and AATI’s board of directors must determine in its good faith judgment, after consultation with a nationally recognized independent financial advisor, that the terms of the proposal are more favorable to the AATI stockholders than the transactions contemplated by the merger agreement, taking into account all the terms and conditions of the proposal and the merger agreement (including any proposal by Skyworks to amend the terms of the merger agreement). AATI’s board of directors must also determine that the terms of the other proposal are reasonably capable of being completed on the terms proposed, taking into account all financial, regulatory, legal and other aspects of such proposal. No proposal will qualify as a superior proposal if any financing required to consummate the proposal is not committed.

Change in Recommendation by AATI’s Board


	•	AATI’s board of directors must have received an alternative acquisition proposal and it must have determined in good faith (after consultation with its financial advisors and outside legal counsel) that the other proposal constitutes a superior proposal;

	•	the failure to take such action would reasonably be expected to be a breach of its fiduciary duties;

	•	AATI stockholders must not have adopted the merger agreement and approved the merger;

	•	AATI must not have violated, in any material respect, any of the terms of the “no-shop” restrictions described above in connection with such acquisition proposal;


	•	AATI must have given Skyworks at least three business days’ prior written notice of its intention to take such action (and the notice must have included the terms and conditions of the other proposal);

	•	no later than the time of such notice, AATI must have provided Skyworks with a copy of the relevant proposed transaction agreement and other material documents with the other party;

	•	if requested by Skyworks, AATI must have negotiated in good faith with Skyworks during the three business day notice period to enable Skyworks to propose changes to the terms of the merger agreement that would cause the other proposal to no longer constitute a superior proposal;

	•	AATI’s board of directors must have considered in good faith (after consultation with its financial advisors and outside legal counsel) any changes to the merger agreement proposed by Skyworks in a written offer capable of acceptance and must have determined that the other proposal would continue to constitute a superior proposal even if the changes proposed by Skyworks were made to the merger agreement; and

	•	in the event of any material change to the financial or other material terms of the other proposal, AATI must have delivered to Skyworks an additional notice and copies of the relevant proposed transaction agreement and other material documents, with a new three business day notice period.

Stockholders Meeting

AATI has agreed to convene and hold a stockholders meeting, as promptly as practicable after the registration statement on Form S-4, of which this proxy statement/prospectus forms a part, has been declared effective by the SEC, for the purpose of obtaining the approval of AATI stockholders for the adoption of the merger agreement and the approval of the merger.

Unless AATI’s board makes an adverse recommendation change or the merger agreement is otherwise terminated in accordance with its terms, AATI, through its board of directors, is required to recommend to its stockholders that they adopt the merger agreement and approve the merger and other transactions contemplated by the merger agreement, include such recommendation in this proxy statement/prospectus, and publicly reaffirm such recommendation in connection with any communication in response to a tender or offer for shares of AATI common stock.

Efforts to Consummate the Merger; Regulatory Matters

Skyworks and AATI have agreed to use commercially reasonable efforts to make all required filings under securities and antitrust laws (and any other applicable laws), to obtain all governmental and private consents, licenses, permits, waivers, approvals, authorizations and orders (if any) that are required for the completion of the merger, to execute or deliver any additional instruments necessary to consummate the merger and carry out the purposes of the merger agreement, and generally to do what is necessary to consummate the merger, in each case as promptly as reasonably practicable. In this regard, Skyworks and AATI have also agreed to cooperate with one another and furnish to each other relevant documents and information (including all information required to be included in the proxy statement/prospectus that is included in this registration statement).

The parties are not required to incur any material or commercially unreasonable expense or to take any commercially unreasonable action in response to any governmental request for information under any antitrust law, or to initiate or pursue litigation against any governmental entity, or to contest or resist any action, including any legislative, administrative or judicial action, or to have vacated, lifted, reversed or overturned any antitrust order that (whether temporary, preliminary or permanent) restricts, prevents or prohibits the consummation of the merger or any other transactions contemplated by the merger agreement. In addition, neither Skyworks nor any of its affiliates have any obligation to make or accept any proposal, execute or carry out any agreement or submit to any order providing for the sale or other disposition or divestiture or holding

separate (through the establishment of a trust or otherwise) of any assets or categories of assets of Skyworks or any of its subsidiaries or AATI or any of its subsidiaries or the holding separate of the shares of AATI common stock or imposing or seeking to impose any material limitation on the ability of Skyworks or any of its subsidiaries to conduct their business or own such assets or to acquire, hold or exercise full rights of ownership of the shares of AATI common stock, or to take any action if the U.S. Department of Justice or Federal Trade Commission authorizes its staff to seek a preliminary injunction or restraining order to enjoin consummation of the merger.

Indemnification, Exculpation and Insurance

Employee Matters

As a general matter, Skyworks has agreed to cause the surviving corporation in the merger to honor all AATI employee benefit plans and compensation arrangements in accordance with their terms as in effect immediately prior to the effective time of the merger. Notwithstanding this commitment, Skyworks and the surviving corporation may amend or terminate any AATI employee benefit plan, arrangement or agreements in accordance with its terms or if otherwise required or permitted by applicable law

After the merger, until the end of Skyworks’ current fiscal year or the end of the applicable current plan year, as Skyworks shall prescribe in its sole discretion, Skyworks has agreed to cause the surviving corporation to maintain, for the benefit of each AATI employee who continues to be employed by Skyworks and its subsidiaries, the AATI employee benefit plans (or substitute plans), at benefit levels that, taken as a whole, are not materially less favorable, in the aggregate, to the continuing employees than the AATI plans in effect on May 26, 2011. Alternatively, Skyworks may cause the surviving corporation to provide compensation and benefits that, taken as a whole, are not materially less favorable in the aggregate than the compensation and benefits provided to comparably ranked, similarly situated employees of Skyworks and its subsidiaries generally, giving effect to differences based on location of employment, performance reviews and other differentiating factors. Neither Skyworks nor the surviving corporation has any obligation to offer, grant or maintain any equity-based compensation and benefits, compensation and benefits under individual employment, severance and/or change-of-control agreements and arrangements, special bonuses, and similar compensation and benefits. Nothing in the merger agreement gives any entitlement to any AATI employee to continued employment with Skyworks or any of its subsidiaries after the merger.

Subject to certain limitations, Skyworks has also agreed to cause the surviving corporation to take commercially reasonable action to provide the continuing employees with credit for their service with AATI

for purposes of vesting, eligibility, participation and level of benefits (but not benefit accruals) under all applicable employee benefit plans and arrangements of Skyworks and its subsidiaries in which AATI employees participate after the effective time. Subject to the requirements and limitations of applicable law and plans, Skyworks has also agreed to cause the surviving corporation to obtain waiver of evidence-of-insurability requirements, waiting periods, and any limitations as to preexisting medical conditions under the group health plan applicable to AATI employees.

Conditions to the Merger

The obligations of AATI and Skyworks to complete the merger are subject to the following conditions (among others):


	•	the adoption of the merger agreement and the approval of the merger by AATI’s stockholders;

	•	the expiration or termination of the applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the “HSR Act”), if any, and applicable foreign laws;

	•	the receipt of all authorizations, consents, orders or approvals of, and the making of all declarations or filings with any governmental entity in connection with the merger and the other transactions contemplated by the merger agreement, the expiration or termination of all waiting periods, and the absence of any material condition to the receipt or issuance of such authorizations, consents, orders, approvals, expiration or termination in connection with the consummation of the Merger or any of the other transactions contemplated by the merger agreement;

	•	the absence of any order, executive order, stay, decree, judgment or injunction (preliminary or permanent) or statute, rule or regulation by any governmental entity which is in effect and which has the effect of making the merger illegal or otherwise prohibiting or imposing any material condition on the consummation of the merger or the other transactions contemplated by the merger agreement;

	•	the filing with Nasdaq (if required) of a notification for listing of the shares of Skyworks common stock to be issued in the merger; and

	•	the effectiveness under the Securities Act of 1933, as amended (the “Securities Act”), of the registration statement, of which this proxy statement/prospectus forms a part, and the absence of any pending or threatened stop order suspending the effectiveness of such registration statement.

In addition, Skyworks’ obligation to complete the merger is subject to the following additional conditions:


	•	the accuracy of AATI’s representations and warranties to the extent required by the merger agreement;

	•	by AATI, if there has been a breach or nonperformance of any representation, warranty, covenant or agreement in the merger agreement on the part of Skyworks, which would cause any of the conditions to AATI’s obligations relating to Skyworks’ representations and warranties or Skyworks’ performance of covenants and agreements not to be satisfied, and that breach has not been cured within ten days after receipt by Skyworks of written notice of such breach or nonperformance from AATI; or

Transaction Fees and Expenses; Termination Fee

Each party will generally pay its own fees and expenses in connection with the merger agreement, the merger and the other transactions contemplated by the merger agreement, whether or not the merger is completed. In certain circumstances, however, AATI will be required to reimburse Skyworks’ expenses (up to $500,000) or to pay Skyworks a termination fee of $8,500,000. The termination fee is payable by AATI if:


	•	Skyworks terminates the merger agreement because (i) AATI’s board of directors has withdrawn or changed its recommendation of the merger agreement and the merger, (ii) AATI’s board of directors has approved or recommended an alternative acquisition agreement, (iii) following a request to do so by Skyworks or following a third-party tender or exchange offer for AATI shares, AATI has failed to publicly reaffirm its recommendation of the merger agreement, (iv) AATI has breached its “no shop” covenants or its covenant to hold the special stockholders’ meeting, or (v) AATI has not held the special meeting and submitted the merger agreement and merger to AATI stockholders on or before December 30, 2011 for any reason other than a court order prohibiting the meeting or vote;

	•	AATI terminates the merger agreement to enter into an alternative acquisition agreement;

	•	by Skyworks or AATI if the special meeting has been held and a vote of AATI stockholders on the merger agreement and merger has been taken, and AATI stockholders have not adopted the merger agreement and approved the merger by the requisite vote, and prior to the vote an alternative acquisition proposal relating to AATI has been announced which has not been absolutely and unconditionally withdrawn and abandoned, and within twelve months after termination a transaction is consummated effecting an alternative acquisition proposal involving a business combination or 50% or more of AATI’s stock or assets or AATI or any of its subsidiaries enters into an agreement contemplating an alternative acquisition proposal involving a business combination or 50% or more of AATI’s stock or assets; or

	•	by Skyworks for a breach or nonperformance by AATI of a covenant or agreement (but not for breaches of representations and warranties) if, before the breach or nonperformance by AATI, a third party has announced or communicated to AATI an alternative acquisition proposal involving a business combination or at least 50% or more of AATI’s stock or assets and the proposal has not been absolutely


		and unconditionally withdrawn and abandoned and within twelve months after such termination a transaction is consummated effecting an alternative acquisition proposal involving a business combination or 50% or more of AATI’s stock or assets or AATI or any of its subsidiaries enters into an agreement contemplating an acquisition proposal involving a business combination or 50% or more of AATI’s stock or assets.

The merger agreement requires AATI to reimburse Skyworks for up to $500,000 of its expenses incurred in connection with the merger agreement and the transactions contemplated thereby if AATI or Skyworks terminate the merger agreement because AATI’s stockholders did not adopt the merger agreement and approve the merger at the special meeting.

In no event will AATI be required to pay both the termination fee and Skyworks’ and Merger Sub’s expenses.

Other Covenants and Agreements

The merger agreement contains other covenants and agreements, including covenants and agreements relating to public announcements regarding the merger, notification of certain developments, and other matters.

Extension, Waiver and Amendment of the Merger Agreement

AATI, Skyworks and Merger Sub may amend the merger agreement at any time prior to the completion of the merger. However, after the adoption of the merger agreement and approval of the merger by AATI’s stockholders, no amendment can be made that by law requires further approval by AATI’s stockholders without obtaining such further approval.

AATI, Skyworks or Merger Sub may extend the time for performance of any of the obligations or other acts of the other parties under the merger agreement, waive any inaccuracies in another party’s representations and warranties and waive compliance with any of the agreements or conditions contained in the merger agreement. However, after the approval and adoption of the merger agreement by AATI’s stockholders, no waiver can be made that by law requires further approval by AATI’s stockholders without obtaining such further approval.

THE STOCKHOLDER AGREEMENT

In connection with the merger agreement, Skyworks entered into a stockholder agreement with certain of the officers and directors of AATI (namely, Richard K. Williams, Samuel J. Anderson, Jason L. Carlson, Jaff Lin, Thomas P. Redfern, Chandramohan Subramanian, Jun-Wei Chen, Ashok Chandran and Kevin D’Angelo). Pursuant to the stockholder agreement, each signing stockholder has agreed to vote all shares of AATI common stock beneficially owned by such stockholder in favor of adoption of the merger agreement and approval of the merger and the other transactions contemplated by the merger agreement and against any other acquisition proposal or alternative acquisition agreement made in opposition to the consummation of the merger and the transactions contemplated by the merger agreement. The signing stockholders have also granted Skyworks an irrevocable proxy to vote their shares of AATI common stock at any meeting of AATI stockholders called with respect to the adoption of the merger agreement and approval of the merger and the other transactions contemplated by the merger agreement.

Under the terms of the stockholder agreement, any shares of AATI common stock received upon the exercise of stock options or the settlement of restricted stock units by the stockholders who have signed the stockholder agreement are subject to the provisions of the stockholder agreement.

The stockholder agreement terminates upon the earlier to occur of (a) the effective time of the merger or (b) any termination of the merger agreement in accordance with its terms, and the proxy granted by the signing stockholders to Skyworks terminates automatically upon termination of the stockholder agreement. In addition, each signing stockholder signed the stockholder agreement solely in his capacity as owner of his shares of AATI common stock, and nothing in the stockholder agreement prohibits, prevents or precludes such

stockholder from taking or not taking any action in his or her capacity as an officer or director of AATI, to the extent permitted by the merger agreement. Under certain circumstances, the merger agreement allows AATI’s board of directors to withdraw its support for the merger agreement and, in certain circumstances, including circumstances involving the receipt of an unsolicited superior proposal, to terminate the merger agreement. If the merger agreement is terminated in accordance with its terms, the stockholder agreement terminates concurrently with the termination of the merger agreement and the proxy granted to Skyworks automatically terminates.

THE NON-COMPETITION AGREEMENT

In connection with the merger agreement, Mr. Richard K. Williams, who is a member of the AATI board of directors and serves as AATI’s president, chief executive officer and chief technical officer, has entered into a non-competition, non-solicitation and confidentiality agreement, dated as of May 26, 2011, (the “non-competition agreement”). Pursuant to the non-competition agreement, Mr. Williams has agreed, for a period of 24 months and subject to certain exceptions, not to engage in any business or activity that is in competition with AATI’s business of developing, designing, manufacturing, licensing, marketing, selling and distributing power management semiconductors and related software. The non-competition agreement is conditioned on the completion of the merger, and if the merger is not completed, the non-competition agreement automatically terminates.

A copy of the non-competition agreement is attached to this proxy statement/prospectus as Annex C.

LEGAL MATTERS

The validity of the Skyworks common stock to be issued in connection with the merger will be passed upon for Skyworks by Wilmer Cutler Pickering Hale and Dorr LLP, Palo Alto, California.

EXPERTS

The consolidated financial statements and related financial statement schedule of Skyworks and its subsidiaries as of October 1, 2010 and October 2, 2009, and for each of the years in the three-year period ended October 1, 2010, and management’s assessment of the effectiveness of internal control over financial reporting as of October 1, 2010 have been incorporated by reference in this prospectus and elsewhere in the registration statement in reliance upon the report of KPMG LLP, independent registered public accounting firm, incorporated by reference, and upon the authority of said firm as experts in accounting and auditing. The audit report covering the October 1, 2010 consolidated financial statements refers to a change in accounting for debt with conversion and other options, with retrospective adjustment for all periods presented in the consolidated financial statements referred to above.

The consolidated financial statements of AATI as of December 31, 2010 and 2009 and for each of the three years in the period ended December 31, 2010 incorporated in this proxy statement/prospectus by reference from AATI’s Annual Report on Form 10-K for the year ended December 31, 2010, and the effectiveness of AATI’s internal control over financial reporting as of December 31, 2010 have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports, which are incorporated herein by reference. Such consolidated financial statements have been so incorporated in reliance upon the report of such firm given upon their authority as experts in auditing and accounting.

OTHER MATTERS

As of the date of this proxy statement/prospectus, AATI does not expect a vote to be taken at the special meeting on any matters other than as described in this proxy statement/prospectus. If any other matters are properly presented at the special meeting for consideration, the holders of proxies, if properly authorized, will have discretion to vote on those matters in accordance within their best judgment.

SUBMISSION OF STOCKHOLDER PROPOSALS

Skyworks

If the merger is completed, AATI’s stockholders will become stockholders of Skyworks. For a stockholder proposal to be considered for possible inclusion in Skyworks’ proxy statement for the annual meeting to be held in 2012, the proposal must be in writing and received by Skyworks’ Corporate Secretary at Skyworks’ principal executive offices no later than the dates set forth below.

For stockholder proposals that are not intended by the stockholder to be included in Skyworks’ proxy materials for next year’s annual meeting, but that the stockholder desires to raise from the floor at the meeting, Skyworks’ amended and restated bylaws establish an advance notice procedure in order to permit such proposals to be brought before an annual meeting of stockholders. In general, notice must be received at Skyworks’ principal executive offices not less than 90 calendar days nor more than 120 calendar days before the one-year anniversary of the previous year’s annual meeting of stockholders. Therefore, to be presented at Skyworks’ 2012 annual meeting of stockholders, such a proposal must be received by Skyworks on or after January 12, 2012 but no later than February 11, 2012. If, however, the date of the annual meeting is more than 30 days earlier or more than 30 days later than such anniversary date, the Corporate Secretary must receive the notice no earlier than 120 days prior to the date of the 2012 annual meeting and no later than the later of 90 days prior to the 2012 annual meeting or the 10th day following the day on which the public announcement of the date of the 2012 annual meeting is first made by Skyworks. Skyworks’ amended and restated bylaws also specify additional requirements as to the form and content of a stockholder’s notice.

101

Pursuant to Rule 14a-8 under the Exchange Act, in order to be considered for inclusion in the proxy materials for Skyworks’ 2012 annual meeting, a stockholder’s proposal must meet the requirements of Rule 14a-8 under the Exchange Act and be delivered in writing to the Secretary of Skyworks at its principal executive offices at 20 Sylvan Road, Woburn, MA 01801, no later than December 2, 2011. The submission of a stockholder proposal does not guarantee that it will be included in the proxy materials for Skyworks’ 2012 annual meeting.

According to the applicable provisions of Skyworks’ By-laws, if a stockholder wishes to nominate a candidate to serve as a director or to present a proposal at Skyworks’ 2012 annual meeting outside the processes of Rule 14a-8 that will not be considered for inclusion in the proxy materials for such meeting, then the stockholder must give written notice to Skyworks’ Corporate Secretary at the address noted above no earlier than January 12, 2011 and no later than February 11, 2012. In the event that the 2012 annual meeting is held more than thirty (30) days before or after the first anniversary of Skyworks’ 2011 annual meeting, then the required notice must delivered in writing to the Secretary of Skyworks at the address above no earlier than 120 days prior to the date of the 2012 annual meeting and no later than the later of 90 days prior to the 2012 annual meeting or the 10th day following the day on which the public announcement of the date of the 2012 annual meeting is first made by Skyworks. A proposal that is submitted outside of these time periods will not be considered to be timely and, pursuant to Rule 14a-4(c)(1) under the Exchange Act and if a stockholder properly brings the proposal before the meeting, the proxies that management solicits for that meeting will have discretionary authority to vote on the stockholder’s proposal. Even if a stockholder makes timely notification, the proxies may still exercise discretionary authority in accordance with the SEC’s proxy rules.

In the case of proposals involving the nomination of directors, the notice must be in writing and must include the nominee’s name and all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors in an election contest, or is otherwise required, in each case pursuant to Regulation 14A under Exchange Act and Rule 14a-11 thereunder. Skyworks’ amended and restated bylaws also require that the notice include the written consent of each nominee to serve as a member of Skyworks’ board of directors, if so elected. Skyworks’ stockholders are also advised to review Skyworks’ amended and restated bylaws, which contain additional requirements with respect to the nomination of directors by stockholders.

All Skyworks stockholder proposals should be addressed to: Corporate Secretary, Skyworks Solutions, Inc., 20 Sylvan Road, Woburn, Massachusetts 01801.

If a stockholder does not want to pursue this method, but would like to make a recommendation of a nominee for director for consideration by Skyworks’ Nominating and Corporate Governance Committee to be included on Skyworks’ slate of directors at the next annual meeting, please follow the procedures outlined under the heading “Committees of the Board of Directors — Director Nomination Procedures” in Skyworks’ definitive proxy statement filed with the SEC on April 7, 2011.

AATI

If the parties consummate the merger, AATI will not have public stockholders, and there will be no public participation in any future meetings of stockholders of AATI. However, if the merger is not consummated, stockholders of AATI will continue to be entitled to attend and participate in stockholders meetings of AATI.

If AATI’s fiscal year 2011 annual meeting of stockholders is held, stockholders may present proper proposals for inclusion in AATI’s proxy statement by submitting their proposal in writing to the Corporate Secretary at AATI’s principal office located at 3230 Scott Blvd., Santa Clara, California 95054, Attn: Corporate Secretary, and otherwise complying with the requirements of Rule 14a-8 of the Exchange Act. The deadline for submission of stockholder proposals intended to be included in AATI’s fiscal year 2011 proxy materials was December 17, 2010. The deadline for stockholder proposals intended to be presented at AATI’s fiscal year 2011 annual meeting of stockholders (which are not otherwise submitted for inclusion in the proxy statement in accordance with Rule 14a-8 of the Exchange Act) was on or after December 17, 2010 but no later than January 16, 2011. If the board of directors of AATI chooses to present a proposal or nomination despite its untimeliness, the people named in the proxies solicited by the board of directors for the 2011

102

annual meeting of stockholders will have the right to exercise discretionary voting power with respect to such proposal or nomination.

HOUSEHOLDING

As permitted by the Exchange Act, only one copy of this proxy statement/prospectus is being delivered to stockholders residing at the same address, unless AATI’s stockholders have notified AATI of their desire to receive multiple copies of its proxy statements. This is known as householding. AATI will promptly deliver, upon oral or written request, a separate copy of this proxy statement/prospectus to any stockholder residing at a shared address to which only one copy was mailed. Requests for additional copies of this proxy statement, or requests to receive multiple or single copies of proxy statements at a shared address in the future, should be directed to AATI’s principal office located at 3230 Scott Blvd., Santa Clara, California 95054, Attn: Corporate Secretary, telephone number: (408) 737-4788.

COMMISSION POSITION ON INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Skyworks’ certificate of incorporation and bylaws provide that the corporation shall indemnify its directors, officers, employees or agents for any liability incurred in their official capacity to the extent permitted under the DGCL. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or persons controlling the registrant pursuant to the foregoing provisions, the registrant has been informed that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is therefore unenforceable.

THIS AGREEMENT AND PLAN OF MERGER (this “Agreement”) is made and entered into as of May 26, 2011 by and among Skyworks Solutions, Inc., a Delaware corporation (the “Buyer”), PowerCo Acquisition Corp., a Delaware corporation and a wholly owned subsidiary of the Buyer (the ‘‘Merger Sub”), and Advanced Analogic Technologies Incorporated, a Delaware corporation (the ‘‘Company”).

WHEREAS, the Boards of Directors of the Buyer, Merger Sub and the Company deem it advisable and in the best interests of their respective corporations and the stockholders of their respective corporations that Merger Sub be merged with and into the Company in accordance with the terms of this Agreement and the General Corporation Law of the State of Delaware (the “DGCL”), with the Company becoming a wholly owned subsidiary of the Buyer (the “Merger”);

WHEREAS, concurrently with the execution and delivery of this Agreement and as a condition and inducement to the Buyer’s willingness to enter into this Agreement, (a) the stockholders of the Company named on Schedule A hereto have entered into the Stockholder Agreement, dated as of the date of this Agreement, in the form attached hereto as Exhibit A (the “Stockholder Agreement”), pursuant to which such stockholders have, among other things, agreed to vote all voting securities of the Company that such stockholders own or control (or over which they exercise voting control) for the approval of the Merger and the adoption of this Agreement; and (b) the stockholder of the Company listed on Schedule 7.2(f) has entered into a Non-competition, Non-solicitation and Confidentiality Agreement (the “Noncompetition Agreement”), pursuant to which he has agreed, among other things, not to compete with the Buyer or the Company for a specified period of time following the Effective Time (the effectiveness of which Noncompetition Agreement is subject, as a condition subsequent, to the occurrence of the Effective Time);

NOW, THEREFORE, in consideration of the foregoing and the respective representations, warranties, covenants and agreements set forth below, the Buyer, Merger Sub and the Company agree as follows:

ARTICLE I

THE MERGER

1.1 Effective Time of the Merger. Subject to the provisions of this Agreement, prior to the Closing, the Buyer shall prepare, and on the Closing Date or as soon as practicable thereafter the Buyer shall cause to be filed with the Secretary of State of the State of Delaware, a certificate of merger (the “Certificate of Merger”) in such form as is required by, and executed by the Surviving Corporation in accordance with, the relevant provisions of the DGCL and shall make all other filings or recordings required under the DGCL. The Merger shall become effective upon the filing of the Certificate of Merger with the Secretary of State of the State of Delaware or at such later time as is established by the Buyer and the Company and set forth in the Certificate of Merger (the “Effective Time”).

1.2 Closing. The closing of the Merger (the “Closing”) shall take place at 9:00 a.m., Pacific time, on a date to be specified by the Buyer and the Company (the ‘‘Closing Date”), which shall be no later than the second business day after satisfaction or waiver of the conditions set forth in Article VII (other than delivery of items to be delivered at the Closing and other than satisfaction of those conditions that by their nature are to be satisfied at the Closing, it being understood that the occurrence of the Closing shall remain subject to the delivery of such items and the satisfaction or waiver of such conditions at the Closing), at the offices of Wilmer Cutler Pickering Hale and Dorr LLP, 950 Page Mill Road, Palo Alto, California, unless another date, place or time is agreed to in writing by the Buyer and the Company.

1.3 Effects of the Merger. At the Effective Time (i) the separate existence of Merger Sub shall cease and Merger Sub shall be merged with and into the Company (the Company following the Merger is sometimes referred to herein as the “Surviving Corporation”) and (ii) the Certificate of Incorporation of the Company as in effect immediately prior to the Effective Time shall be amended in its entirety so that such Certificate of

Incorporation is identical to the Certificate of Incorporation of Merger Sub as in effect immediately prior to the Effective Time, except that (A) all references to the name of Merger Sub therein shall be changed to refer to the name of the Company and (B) the identity of the incorporator shall be deleted and, as so amended, such Certificate of Incorporation shall be the Certificate of Incorporation of the Surviving Corporation, until further amended in accordance with the DGCL. In addition, the Buyer shall cause the By-laws of the Company as in effect immediately prior to the Effective Time to be amended and restated in their entirety so that, immediately following the Effective Time, they are identical to the By-laws of Merger Sub as in effect immediately prior to the Effective Time, except that all references to the name of Merger Sub therein shall be changed to refer to the name of the Company, and, as so amended and restated, such By-laws shall be the By-laws of the Surviving Corporation, until further amended in accordance with the DGCL. The Merger shall have the effects set forth in Section 259 of the DGCL.

1.4 Directors and Officers. The directors and officers of Merger Sub immediately prior to the Effective Time shall be the initial directors and officers of the Surviving Corporation, each to hold office in accordance with the Certificate of Incorporation and By-laws of the Surviving Corporation.

2.1 Conversion of Capital Stock. As of the Effective Time, by virtue of the Merger and without any action on the part of the holder of any shares of the capital stock of the Company or capital stock of Merger Sub:

(a) Capital Stock of Merger Sub. Each share of the common stock of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and become one fully paid and nonassessable share of common stock, $.01 par value per share, of the Surviving Corporation.

(b) Cancellation of Treasury Stock and Buyer-Owned Stock. All shares of common stock, $0.001 par value per share, of the Company (“Company Common Stock”) that are owned by the Company as treasury stock or by any wholly owned subsidiary of the Company and any shares of Company Common Stock owned by the Buyer, Merger Sub or any other wholly owned subsidiary of the Buyer immediately prior to the Effective Time shall be cancelled and shall cease to exist and no stock of the Buyer or other consideration shall be delivered in exchange therefor.

(c) Exchange Ratio for Company Common Stock. Subject to the provisions of Section 2.2, each share of Company Common Stock (other than shares to be cancelled in accordance with Section 2.1(b) and other than Dissenting Company Shares under Section 2.4) issued and outstanding immediately prior to the Effective Time shall be automatically converted into the right to receive, upon surrender of the certificate representing such share of Company Common Stock in the manner provided in Section 2.2, a cash payment in the amount of $3.68 (as the same may be adjusted in accordance herewith, the “Cash Amount”) plus 0.08725 of a share of Buyer Common Stock (the “Stock Amount”) (the Cash Amount and the Stock Amount are together referred to as the “Merger Consideration”); provided, however, that if the product of the Stock Amount and the average last reported sale price of Buyer Common Stock (at the 4:00 p.m., Eastern Time, end of regular trading hours) on the five (5) full trading days ending on the trading day immediately prior to the date on which the Effective Time occurs (such average, the ‘‘Average Price,” and such product, the “Closing Value”) is less than $2.45, then the Cash Amount shall be increased by the difference between the $2.45 and the Closing Value and if the Closing Value is more than $2.45, then the Cash Amount shall be reduced by the difference between the Closing Value and $2.45 (but in no event shall the Cash Amount as reduced be less than zero); but provided, further, that if the Average Price is less than $21.00, then Buyer shall have the right to pay the entire Merger Consideration in cash, and in such case the Cash Amount will be $6.13 and the Stock Amount will be zero. For purposes of this Agreement, ‘‘Buyer Common Stock” means common stock, $0.25 par value per share, of the Buyer. As of the Effective Time, all such shares of Company Common Stock

shall no longer be outstanding and shall automatically be cancelled and shall cease to exist, and each holder of a certificate representing any such shares of Company Common Stock shall cease to have any rights with respect thereto, except the right to receive the shares of Buyer Common Stock pursuant to this Section 2.1(c) and any cash in lieu of fractional shares of Buyer Common Stock to be issued or paid in consideration therefor upon the surrender of such certificate in accordance with Section 2.2, without interest, subject to the provisions of Section 2.4.

(d) Adjustments to Exchange Ratio. The Merger Consideration shall be adjusted to reflect fully the effect of any reclassification, stock split, reverse split, stock dividend (including any dividend or distribution of securities convertible into Buyer Common Stock or Company Common Stock), reorganization, recapitalization or other like change with respect to Buyer Common Stock or Company Common Stock occurring (or for which a record date is established) after the date hereof and prior to the Effective Time.

(e) Unvested Stock. At the Effective Time, any shares of Buyer Common Stock issued in accordance with Section 2.1(c) with respect to any unvested shares of Company Common Stock awarded to employees, directors or consultants pursuant to any of the Company’s plans or arrangements and outstanding immediately prior to the Effective Time shall remain subject to the same terms, restrictions and vesting schedule as in effect immediately prior to the Effective Time, except to the extent by their terms such unvested shares of Company Common Stock vest at the Effective Time. The Company shall not take or permit any action which would accelerate vesting of any unvested shares, except to the extent required by the terms of an agreement or plan “made available” to the Buyer (as defined in Section 9.8) that is applicable to such shares in effect on the date hereof. Copies of the relevant agreements governing such shares and the vesting thereof have been provided to the Buyer. All outstanding rights which the Company may hold immediately prior to the Effective Time to repurchase unvested shares of Company Common Stock shall be assigned to the Buyer in the Merger and shall thereafter be exercisable by the Buyer upon the same terms and conditions in effect immediately prior to the Effective Time, except that the shares purchasable pursuant to such rights and the purchase price payable per share shall be appropriately adjusted to reflect the Option Exchange Ratio. The Company shall take all steps necessary to cause the foregoing provisions of this Section 2.1(e) to occur.

2.2 Exchange of Company Certificates. The procedures for exchanging outstanding shares of Company Common Stock for Buyer Common Stock pursuant to the Merger are as follows:

(a) Exchange Agent. As of the Effective Time, the Buyer shall deposit with the Buyer’s transfer agent or another bank or trust company designated by the Buyer and reasonably acceptable to the Company (the “Exchange Agent”), for the benefit of the holders of shares of Company Common Stock, for exchange in accordance with this Section 2.2, through the Exchange Agent, (i) the aggregate amount of cash and certificates representing the aggregate number of shares of Buyer Common Stock (such cash and shares of Buyer Common Stock being hereinafter referred to as the “Exchange Fund”) issuable pursuant to Section 2.1 in exchange for outstanding shares of Company Common Stock, (ii) cash in an amount sufficient to make the payments for fractional shares required pursuant to Section 2.2(c), and (iii) any dividends or distributions to which holders of certificates which immediately prior to the Effective Time represented outstanding shares of Company Common Stock (the “Company Certificates”) whose shares were converted pursuant to Section 2.1 into the right to receive shares of Buyer Common Stock may then be entitled pursuant to Section 2.2(e).

(b) Exchange Procedures. As soon as reasonably practicable after the Effective Time, the Exchange Agent shall mail to each holder of record of a Company Certificate (i) a letter of transmittal (which shall specify that delivery shall be effected, and risk of loss and title to the Company Certificates shall pass, only upon delivery of the Company Certificates to the Exchange Agent and shall be in customary form with such provisions as the Buyer and the Company may reasonably agree) and (ii) instructions for effecting the surrender of the Company Certificates in exchange for the applicable cash amount and certificates representing the applicable number of shares of Buyer Common Stock (plus cash in lieu of fractional shares, if any, of Buyer Common Stock and any dividends or distributions as provided below). Upon surrender of a Company Certificate for cancellation to the Exchange Agent or to such other agent or agents as may be appointed by the

A-9

EXECUTION COPY

Buyer, together with such letter of transmittal, duly executed, and such other documents as may reasonably be required by the Exchange Agent, the holder of such Company Certificate shall be entitled to receive in exchange therefor the cash amount which such holder has the right to receive pursuant to the provisions of this Article II and a certificate representing the number of whole shares of Buyer Common Stock which such holder has the right to receive pursuant to the provisions of this Article II, plus cash in lieu of fractional shares pursuant to Section 2.2(c) and any dividends or distributions then payable pursuant to Section 2.2(d), and the Company Certificate so surrendered shall immediately be cancelled. In the event of a transfer of ownership of Company Common Stock which is not registered in the transfer records of the Company, the applicable cash amount and a certificate representing the proper number of shares of Buyer Common Stock, plus cash in lieu of fractional shares pursuant to Section 2.2(c) and any dividends or distributions then payable pursuant to Section 2.2(d), may be issued or paid to a person other than the person in whose name the Company Certificate so surrendered is registered, if such Company Certificate is presented to the Exchange Agent, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.2, each Company Certificate shall be deemed at any time after the Effective Time to represent only the right to receive upon such surrender the applicable cash amount and a certificate or certificates representing the applicable number of shares of Buyer Common Stock that the holder of such Company Certificate has the right to receive pursuant to the provisions of this Article II, plus cash in lieu of fractional shares pursuant to Section 2.2(c) and any dividends or distributions then payable pursuant to Section 2.2(d), as contemplated by this Section 2.2, subject to the provisions of Section 2.4.

(c) No Fractional Shares. No certificate or scrip representing fractional shares of Buyer Common Stock shall be issued upon the surrender for exchange of Company Certificates, and such fractional share interests shall not entitle the owner thereof to vote or to any other rights of a stockholder of the Buyer. Notwithstanding any other provision of this Agreement, each holder of shares of Company Common Stock converted pursuant to the Merger who would otherwise have been entitled to receive a fraction of a share of Buyer Common Stock (after taking into account all Company Certificates delivered by such holder and the aggregate number of shares of Company Common Stock represented thereby) shall receive, in lieu thereof, cash (without interest) in an amount equal to such fractional part of a share of Buyer Common Stock multiplied by the average of the last reported sales prices of Buyer Common Stock at the 4:00 p.m., Eastern time, end of regular trading hours on Nasdaq during the ten (10) consecutive trading days ending on the last trading day prior to the Effective Time.

(d) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time with respect to Buyer Common Stock with a record date after the Effective Time shall be paid to the holder of any unsurrendered Company Certificate until the holder of record of such Company Certificate shall surrender such Company Certificate. Subject to the effect of applicable laws, following surrender of any such Company Certificate, there shall be issued and paid to the record holder of the Company Certificate, at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time previously paid with respect to such whole shares of Buyer Common Stock, without interest, and, at the appropriate payment date, the amount of dividends or other distributions having a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender that are payable with respect to such whole shares of Buyer Common Stock.

(e) No Further Ownership Rights in Company Common Stock. All shares of Buyer Common Stock issued upon the surrender for exchange of Company Certificates in accordance with the terms hereof (including any cash or dividends or other distributions paid pursuant to Sections 2.2(c) or 2.2(d)) shall be deemed to have been issued (and paid) in full satisfaction of all rights pertaining to such shares of Company Common Stock, and from and after the Effective Time there shall be no further registration of transfers on the stock transfer books of the Surviving Corporation of the shares of Company Common Stock which were outstanding immediately prior to the Effective Time. If, after the Effective Time, Company Certificates are

A-10

EXECUTION COPY

presented to the Surviving Corporation or the Exchange Agent for any reason, they shall be cancelled and exchanged as provided in this Article II.

(f) Termination of Exchange Fund. Any portion of the Exchange Fund which remains undistributed to the holders of Company Common Stock for one hundred eighty (180) after the Effective Time shall be delivered to the Buyer, upon demand, and any holder of Company Common Stock who has not previously complied with this Section 2.2 shall thereafter look only to the Buyer, as a general unsecured creditor, for payment of its claim for Buyer Common Stock, any cash in lieu of fractional shares of Buyer Common Stock and any dividends or distributions with respect to Buyer Common Stock.

(g) No Liability. To the extent permitted by applicable law, none of the Buyer, Merger Sub, the Company, the Surviving Corporation or the Exchange Agent shall be liable to any holder of shares of Company Common Stock or Buyer Common Stock, as the case may be, for such shares (or dividends or distributions with respect thereto) delivered to a public official pursuant to any applicable abandoned property, escheat or similar law. If any Company Certificate shall not have been surrendered prior to one (1) year after the Effective Time (or immediately prior to such earlier date on which any shares of Buyer Common Stock, and any cash payable to the holder of such Company Certificate or any dividends or distributions payable to the holder of such Company Certificate pursuant to this Article II would otherwise escheat to or become the property of any Governmental Entity), any such shares of Buyer Common Stock or cash, dividends or distributions in respect of such Company Certificate shall, to the extent permitted by applicable law, become the property of the Surviving Corporation, free and clear of all claims or interest of any person previously entitled thereto.

(h) Withholding Rights. Each of the Buyer and the Surviving Corporation shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as it reasonably determines that it is required to deduct and withhold with respect to the making of such payment under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”) or any other applicable provision of law. To the extent that amounts are so withheld by the Surviving Corporation or the Buyer, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by the Surviving Corporation or the Buyer, as the case may be.

(i) Lost Company Certificates. If any Company Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Company Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond in such reasonable amount as the Surviving Corporation may direct as indemnity against any claim that may be made against it with respect to such Company Certificate, the Exchange Agent shall issue in exchange for such lost, stolen or destroyed Company Certificate the shares of Buyer Common Stock and any cash in lieu of fractional shares, and unpaid dividends and distributions on shares of Buyer Common Stock deliverable in respect thereof pursuant to this Agreement.

2.3 Company Stock Plans.

(a) At the Effective Time, each outstanding option to purchase Company Common Stock (each, a ‘‘Company Option”), whether vested or unvested, and all stock option plans or other equity-related plans of the Company (the “Company Stock Plans”) themselves, insofar as they relate to outstanding Company Options, shall be assumed by the Buyer and each Company Option shall become an option to acquire, on the same terms and conditions as were applicable under the Company Option immediately prior to the Effective Time, a number of shares of Buyer Common Stock equal to the product of (i) the number of shares of Company Common Stock subject to such Company Option immediately prior to the Effective Time multiplied by (ii) the quotient obtained from dividing $6.13 by the Average Price (the “Option Exchange Ratio”) (rounded down to the nearest whole number), at a price per share of Buyer Common Stock (rounded up to the nearest whole cent) equal to the quotient obtained from dividing (x) the exercise price per share for the shares

A-11

EXECUTION COPY

of Company Common Stock purchasable pursuant to the assumed Company Option immediately prior to the Effective Time by (y) the Option Exchange Ratio. Such Company Options shall continue in effect on the same terms and conditions to which they are subject (subject to the adjustments required by this Section 2.3 after giving effect to the Merger).

(b) As soon as practicable after the Effective Time, the Buyer shall deliver to the participants in the Company Stock Plans an appropriate notice setting forth such participants’ rights pursuant to the Company Options, as provided in this Section 2.3.

(c) The Buyer shall take all corporate action necessary to reserve for issuance a sufficient number of shares of Buyer Common Stock for delivery upon exercise of the Company Options assumed in accordance with this Section 2.3. As soon as practicable (but in no event more than ten (10) business days after the Effective Time, the Buyer shall file a registration statement on Form S-8 (or any successor form) or another appropriate form with respect to the shares of Buyer Common Stock subject to such options, and thereafter shall use commercially reasonable efforts to maintain the effectiveness of that registration statement for as long as any such Company Options remain outstanding.

(d) The Company shall (i) terminate its 2005 Employee Stock Purchase Plan (the “ESPP”) in accordance with its terms as of or prior to the Effective Time, (ii) provide notice as required in Section 19(c) of the ESPP, and (iii) not commence any new offering period under the ESPP after the date of this Agreement.

(e) At the Effective Time, each outstanding award of Company restricted stock units (“Company Restricted Stock Units”) that is to be settled in Company Common Stock that is outstanding immediately prior to the Effective Time shall be assumed by the Buyer (each, an “Assumed Restricted Stock Unit”). In accordance with its terms, each Assumed Restricted Stock Unit shall be converted into a restricted stock unit to acquire that number of shares of Buyer Common Stock equal to the product obtained by multiplying (x) the number of shares of Company Common Stock subject to such Company Restricted Stock Unit, and (y) the Option Exchange Ratio, rounded down to the nearest whole share of Buyer Common Stock. Each Assumed Restricted Stock Unit shall otherwise be subject to the same terms and conditions (including as to vesting) as were applicable under the respective Company Restricted Stock Units immediately prior to the Effective Time.

2.4 Dissenting Shares.

(a) Notwithstanding anything to the contrary contained in this Agreement, shares of Company Common Stock held by a holder who has neither voted in favor of the Merger Agreement or the Merger nor consented thereto in writing and who has properly and validly perfected their statutory rights of appraisal in respect of such shares of Company Common Stock in accordance with Section 262 of the DGCL (any such shares being referred to as “Dissenting Shares” until such time as such holder fails to perfect or otherwise loses such holder’s appraisal rights under the DGCL with respect to such shares) shall not be converted into or represent the right to receive Merger Consideration in accordance with Section 2.1, but shall be entitled only to such rights as are granted by the DGCL to a holder of Dissenting Shares.

(b) If any Dissenting Shares shall lose their status as such (through failure to perfect or otherwise), then, as of the later of the Effective Time or the date of loss of such status, such shares shall automatically be converted into and shall represent only the right to receive Merger Consideration in accordance with Section 2.1, without interest thereon, upon surrender of the Certificate formerly representing such shares.

(c) The Company shall give the Buyer: (i) prompt notice of any written demand for appraisal received by the Company prior to the Effective Time pursuant to the DGCL, any withdrawal of any such demand and any other demand, notice, filings, correspondence or instrument delivered to the Company prior to the Effective Time pursuant to the DGCL that relate to such demand; and (ii) the opportunity to participate in all negotiations and proceedings with respect to any such demand, notice or instrument. The Company shall not voluntarily make any payment or make or accept any settlement offer prior to the Effective Time with respect to any such demand, notice or instrument unless the Buyer shall have given its prior express written consent to such payment or settlement offer (which consent will not be unreasonably withheld).

For purposes of this Agreement, the term “Company Material Adverse Effect” means any effect, circumstance, change, event and/or development (each an “Effect”, and collectively, ‘‘Effects”) that, either individually or in the aggregate, and taken together with all other Effects, has (or have) a material adverse effect on the business, assets, liabilities, condition (financial or otherwise), operations or results of operations of the Company and its Subsidiaries, taking the Company together with its Subsidiaries as a whole; provided, however, that no Effect (either by itself or when aggregated or taken together with any and all other such Effects) proximately caused by any of the matters described in clauses (a), (b), (c), (g) or (h) or resulting directly and primarily from any of the matters described in clauses (d), (e) or (f) below shall be deemed to be or to constitute a “Company Material Adverse Effect,” and no Effect (either by itself or when aggregated or taken together with any and all other such Effects) proximately caused by any of the matters described in clauses (a), (b), (c), (g) or (h) or resulting directly and primarily from any of the matters described in clauses (d), (e), or (f) below shall be taken into account when determining whether a “Company Material Adverse Effect” has occurred or may occur:

(a) general economic conditions in the United States, China or any other country (or changes therein), general conditions in the financial markets in the United States, China or any other country (or changes therein), or general political conditions in the United States, China or any other country (or changes therein), in any such case to the extent that such conditions or changes do not affect the Company and its Subsidiaries in a disproportionate manner relative to other participants in the industries in which the Company and its Subsidiaries conduct business;

(b) general conditions in the industries in which the Company and its Subsidiaries conduct business (or changes therein) to the extent that such conditions or changes do not affect the Company and its Subsidiaries in a disproportionate manner relative to other participants in the industries in which the Company and its Subsidiaries conduct business;

(f) changes in GAAP (or the interpretation thereof) that affect the consolidated financial statements of the Company and its Subsidiaries;

(g) changes (in and of themselves) in the trading price or volume of the Company’s stock (it being understood, acknowledged and agreed that the underlying causes of, and the facts, circumstances or occurrences giving rise or contributing to such changes may be deemed to constitute a “Company Material Adverse Effect” (unless otherwise excluded by this definition) and may be taken into account in determining whether there has been, is, or would be a Company Material Adverse Effect); or

(h) failure (in and of itself) by the Company to meet any internal or public projections, forecasts or estimates of revenues or earnings (it being understood, acknowledged and agreed that the underlying causes of, and the facts, circumstances or occurrences giving rise or contributing to such failure, and any legal liabilities resulting from such failure, may be deemed to constitute a “Company Material Adverse Effect” (unless otherwise excluded by this definition) and may be taken into account in determining whether there has been, is, or would, could or is likely to be a Company Material Adverse Effect).

For the avoidance of doubt, the parties agree that for all purposes of this Agreement: (i) with respect to the assets and/or liabilities of the Company and its Subsidiaries, an Effect that would otherwise constitute a Company Material Adverse Effect (or would otherwise be considered in determining whether a Company Material Adverse Effect has occurred or would, could or is likely to occur) shall constitute a Company Material Adverse Effect (and shall be considered in determining whether a Company Material Adverse Effect has occurred or would, could or is likely to occur) even if such Effect is a one-time or non-recurring and whether or not the impact of such Effect is permanent, ongoing, long-term or short-term; (ii) the term “business” includes (but is not limited to) the long-term future earnings potential of the Company and its Subsidiaries; (iii) the terms “material”, “materially” or “materiality” as used in this Agreement with an initial lower case “m” shall have their respective customary and ordinary meanings, without regard to the meanings ascribed to Company Material Adverse Effect in this forepart to Article III or to Buyer Material Adverse Effect in Article IV; (iv) when a statement in a representation and warranty in Article III is qualified by the phrase “in all material respects,” materiality shall be determined solely by reference to, and solely within the context of, the particular representation and warranty in which such qualifying phrase is used and not with respect to the entirety of this Agreement or the entirety of the transactions contemplated by this Agreement; and (v) to the extent possible, unless provisions are mutually exclusive and effect cannot be given to both or all such provisions, (A) the representations and warranties, covenants, agreements and closing conditions in this Agreement shall be construed to be cumulative, (B) each representation and warranty, covenant, agreement and closing condition in this Agreement shall be given full separate and independent effect, and (C) no limitation in or exception to any representation and warranty, covenant, agreement or closing condition shall be construed to limit or apply to any other representation and warranty, covenant, agreement or closing condition unless such limitation or exception is expressly made applicable to such other representation and warranty, covenant, agreement or closing condition.

For purposes of this Agreement, the term “Knowledge,” when applicable to the Company in any given provision, means the knowledge of each of the individuals listed in Schedule 3 hereto and the knowledge that each such individual would have obtained after consulting with his or her direct reports with responsibility for the functional, geographic or product areas relating to such provision.

BUYER AND MERGER SUB

The Buyer and Merger Sub represent and warrant to the Company that the statements contained in this Article IV are true and correct, except as expressly set forth (i) herein or (ii) in the disclosure schedule delivered by the Buyer and Merger Sub to the Company on or before the date of this Agreement (the “Buyer Disclosure Schedule”) or (iii) in the Buyer’s Annual Report on Form 10-K for the fiscal year ended October 1, 2010 or the Buyer’s Quarterly Reports on Form 10-Q for the quarters ended December 31, 2010 and April 1, 2011, in each case as filed with the SEC (other than in any “risk factor” disclosure or forward-looking statement or any other disclosure therein that constitutes a general cautionary or predictive statement). The Buyer Disclosure Schedule shall be arranged in sections, subsections, paragraphs and clauses corresponding to the numbered and lettered sections, subsections, paragraphs and clauses contained in this Article IV and the disclosure in any section, subsection, paragraph or clause shall qualify (1) the corresponding section, subsection, paragraph or clause in this Article IV and (2) the other sections, subsections, paragraphs and clauses in this Article IV only to the extent that it is reasonably clear from a reading of such disclosure that it also qualifies or applies to such other sections, subsections, paragraphs and clauses.

For purposes of this Agreement, the term “Buyer Material Adverse Effect” means any effect, circumstance, change, event and/or development (each an “Effect”, and collectively, ‘‘Effects”) that, either individually or in the aggregate, and taken together with all other Effects, has (or have) a material adverse effect on the business, assets, liabilities, condition (financial or otherwise), operations or results of operations of the Buyer and its Subsidiaries, taking the Buyer together with its Subsidiaries as a whole; provided, however, that no Effect (either by itself or when aggregated or taken together with any and all other such Effects) proximately caused by any of the matters described in clauses (a), (b), (c), (g) or (h) or resulting directly and primarily from any of the matters described in clauses (d), (e) or (f) below shall be deemed to be or to constitute a “Buyer Material Adverse Effect,” and no Effect (either by itself or when aggregated or taken together with any and all other such Effects) proximately caused by any of the matters described in clauses (a), (b), (c), (g) or (h) or resulting directly and primarily from any of the matters described in clauses (d), (e), or (f) below shall be taken into account when determining whether a “Buyer Material Adverse Effect” has occurred or may occur:

(a) general economic conditions in the United States or any other country (or changes therein), general conditions in the financial markets in the United States or any other country (or changes therein), or general political conditions in the United States or any other country (or changes therein), in any such case to the

A-33

EXECUTION COPY

extent that such conditions or changes do not affect the Buyer and its Subsidiaries in a disproportionate manner relative to other participants in the industries in which the Buyer and its Subsidiaries conduct business;

(b) general conditions in the industries in which the Buyer and its Subsidiaries conduct business (or changes therein) to the extent that such conditions or changes do not affect the Buyer and its Subsidiaries in a disproportionate manner relative to other participants in the industries in which the Buyer and its Subsidiaries conduct business;

(c) general conditions caused by acts of terrorism, war or armed hostilities to the extent that such acts of terrorism, war or armed hostilities do not affect the Buyer or any of its Subsidiaries directly or in a disproportionate manner relative to other participants in the industries in which the Buyer and its Subsidiaries conduct business;

(d) the response of customers, suppliers, distributors, business partners and employees of the Buyer and its Subsidiaries to the announcement of this Agreement and the pendency of the transactions contemplated hereby;

(e) action taken by the Buyer or its Subsidiaries at the express written request of the Company after the date hereof (and in conformity therewith) that is not required by the terms of this Agreement;

(f) changes in GAAP (or the interpretation thereof) that affect the consolidated financial statements of the Buyer and its Subsidiaries;

(g) changes (in and of themselves) in the trading price or volume of the Buyer’s stock (it being understood, acknowledged and agreed that the underlying causes of, and the facts, circumstances or occurrences giving rise or contributing to such changes may be deemed to constitute a “Buyer Material Adverse Effect” (unless otherwise excluded by this definition) and may be taken into account in determining whether there has been, is, or would be a Buyer Material Adverse Effect); or

(h) failure (in and of itself) by the Buyer to meet any internal or public projections, forecasts or estimates of revenues or earnings (it being understood, acknowledged and agreed that the underlying causes of, and the facts, circumstances or occurrences giving rise or contributing to such failure, and any legal liabilities resulting from such failure, may be deemed to constitute a “Buyer Material Adverse Effect” (unless otherwise excluded by this definition) and may be taken into account in determining whether there has been, is, or would, could or is likely to be a Buyer Material Adverse Effect).

For the avoidance of doubt, the parties agree that for all purposes of this Agreement: (i) with respect to the assets and/or liabilities of the Buyer and its Subsidiaries, an Effect that would otherwise constitute a Buyer Material Adverse Effect (or would otherwise be considered in determining whether a Buyer Material Adverse Effect has occurred or would, could or is likely to occur) shall constitute a Buyer Material Adverse Effect (and shall be considered in determining whether a Buyer Material Adverse Effect has occurred or would, could or is likely to occur) even if such Effect is a one-time or non-recurring and whether or not the impact of such Effect is permanent, ongoing, long-term or short-term; (ii) the term “business” includes (but is not limited to) the long-term future earnings potential of the Buyer and its Subsidiaries; (iii) the terms “material”, “materially” or “materiality” as used in this Agreement with an initial lower case “m” shall have their respective customary and ordinary meanings, without regard to the meanings ascribed to Buyer Material Adverse Effect in this forepart to Article IV or to Company Material Adverse Effect in Article III; (iv) when a statement in a representation and warranty in Article IV is qualified by the phrase “in all material respects,” materiality shall be determined solely by reference to, and solely within the context of, the particular representation and warranty in which such qualifying phrase is used and not with respect to the entirety of this Agreement or the entirety of the transactions contemplated by this Agreement; and (v) to the extent possible, unless provisions are mutually exclusive and effect cannot be given to both or all such provisions, (A) the representations and warranties, covenants, agreements and closing conditions in this Agreement shall be construed to be cumulative, (B) each representation and warranty, covenant, agreement and closing condition in this Agreement shall be given full separate and independent effect, and (C) no limitation in or exception to

A-34

Notwithstanding the foregoing or anything else to the contrary provided herein, at any time prior to the receipt of the Company Stockholder Approval, the Company Board may effect a Change in Recommendation if the Company Board has received an Acquisition Proposal that it determines in good faith (after consultation with its financial advisors and outside legal counsel) constitutes a Superior Proposal and the failure to take such action would reasonably be expected to be a breach of its fiduciary duties, provided that (and only if) (A) the Company has not violated, in any material respect, any of the terms of Section 6.1(a), Section 6.1(b) or this Section 6.1(c) in connection with such Acquisition Proposal, (B) the Company shall have given the Buyer at least three (3) business days’ prior written notice of its intention to take such action (which notice shall include the terms and conditions of any such Superior Proposal) and, no later than the time of such notice, provided the Buyer a copy of the relevant proposed transaction agreement and other material documents with the party making such Superior Proposal,

(C) if requested by the Buyer, the Company shall have negotiated in good faith with Parent during such three (3) business day notice period to enable the Buyer to propose changes to the terms of this Agreement that would cause such Superior Proposal to no longer constitute a Superior Proposal, (D) the Company Board shall have considered in good faith (after consultation with its financial advisors and outside legal counsel) any changes to this Agreement proposed by the Buyer in a written offer capable of acceptance and determined that the Superior Proposal would continue to constitute a Superior Proposal if such changes were to be given effect, and (E) in the event of any material change to the financial or other material terms of such Superior Proposal, the Company shall, in each case, have delivered to Parent an additional notice and copies of the relevant proposed transaction agreement and other material documents and the three (3) business day notice period shall have recommenced. Subject to the provisions of Section 8.1(h), nothing in this Section 6.1 shall be deemed to (A) permit the Company to take any action described in clauses (ii) or (iii) of the first sentence of Section 6.1(b), or (B) affect any obligation of the Company under this Agreement or (C) limit the Company’s obligation to call, give notice of, convene and hold the Company Meeting, regardless of whether the Company Board has made a Change in Recommendation.

Contemporaneously with providing any information to a third party in connection with any such Acquisition Proposal or inquiry, the Company shall furnish a copy of such information to the Buyer.

(e) Certain Permitted Disclosure. Nothing contained in this Section 6.1 or in Section 6.5 shall be deemed to prohibit the Company from taking and disclosing to its stockholders a position with respect to a tender offer contemplated by Rule 14e-2(a) promulgated under the Exchange Act or from making any disclosure to the Company’s stockholders required by law or its fiduciary duties if, in the good faith judgment of the Company Board, after consultation with outside counsel, failure to so disclose would violate the Company Board’s obligations under applicable law; provided, however, that, except as set forth in Section 6.1(b), in no event shall the Company Board or any committee thereof withdraw or modify, or propose to withdraw or modify, its position with respect to this Agreement or the Merger.

(f) Cessation of Ongoing Discussions. The Company shall, and shall cause its Subsidiaries and its and their Representatives to, cease immediately all discussions and negotiations regarding any proposal that constitutes, or could reasonably be expected to lead to, an Acquisition Proposal.

(b) The parties hereto agree that any and all disputes arising under or related in any way to this Agreement or the Transactions shall be resolved solely in arbitration before the Court of Chancery of the State of Delaware (the “Delaware Court of Chancery”) as set forth below. Accordingly, and for the sake of clarity, the parties hereto agree that they are waiving and relinquishing the right to bring any dispute arising under or related in any way to this Agreement or the Merger or other transactions contemplated by this Agreement before a court of any state or the United States; that they are waiving any right to have such dispute decided by a jury; and that they are also waiving any right to argue that the forum for the arbitration is an inconvenient one.

STOCKHOLDER AGREEMENT

THIS STOCKHOLDER AGREEMENT (this “Agreement”) is made and entered into as of May 26, 2011 by and among the stockholders of Advanced Analogic Technologies Incorporated, a Delaware corporation (the “Company”), named on the signature page(s) hereto (collectively, ‘‘Stockholders” and each individually, a “Stockholder”), and Skyworks Solutions, Inc., a Delaware corporation (the “Buyer”). Capitalized terms used and not otherwise defined herein shall have the respective meanings assigned to them in the Merger Agreement referred to below.

WHEREAS, as of the date hereof, the Stockholders collectively own of record and beneficially shares of capital stock of the Company, as set forth on Schedule I hereto (such shares, or any other voting or equity of securities of the Company hereafter acquired by any Stockholder prior to the termination of this Agreement, being referred to herein collectively as the ‘‘Shares”);

WHEREAS, concurrently with the execution of this Agreement, Buyer, Merger Sub and the Company are entering into an Agreement and Plan of Merger, dated as of the date hereof (the “Merger Agreement”), pursuant to which, upon the terms and subject to the conditions thereof, a subsidiary of Buyer will be merged with and into the Company, and the Company will be the surviving corporation (the “Merger”); and

WHEREAS, as a condition to the willingness of Buyer to enter into the Merger Agreement, Buyer has required that the Stockholders agree, and in order to induce Buyer to enter into the Merger Agreement, which provides substantial economic benefits to the Stockholders, the Stockholders are willing to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereby agree, severally and not jointly, as follows:

Section 1. Voting of Shares.

(a) Each Stockholder covenants and agrees that until the termination of this Agreement in accordance with the terms hereof, at the Company Meeting or any other meeting of the stockholders of the Company, however called, and in any action by written consent of the stockholders of the Company, such Stockholder will vote, or cause to be voted, all of his, her or its respective Shares, unless otherwise agreed to in writing by the Buyer, (i) in favor of adoption of the Merger Agreement and approval of the Merger and the other transactions contemplated by the Merger Agreement, as the Merger Agreement may be modified or amended from time to time in a manner not adverse to the Stockholders, and (ii) against any other Acquisition Proposal or Alternative Acquisition Agreement.

(b) Each Stockholder hereby irrevocably grants to, and appoints, the Buyer, and any individual designated in writing by it, and each of them individually, as its proxy and attorney-in-fact (with full power of substitution), for and in its name, place and stead, to vote his, her or its Shares at any meeting of the stockholders of the Company called with respect to any of the matters specified in, and in accordance and consistent with this Section 1. Each Stockholder understands and acknowledges that the Buyer is entering into the Merger Agreement in reliance upon the Stockholder’s execution and delivery of this Agreement. Each Stockholder hereby affirms that the irrevocable proxy set forth in this Section 1(b) is given in connection with the execution of the Merger Agreement, and that such irrevocable proxy is given to secure the performance of the duties of such Stockholder under this Agreement. Except as otherwise provided for herein, each Stockholder hereby (i) affirms that the irrevocable proxy is coupled with an interest and may under no circumstances be revoked, (ii) ratifies and confirms all that the proxies appointed hereunder may lawfully do or cause to be done by virtue hereof and (iii) affirms that such irrevocable proxy is executed and intended to be irrevocable in accordance with the provisions of Section 212(e) of the Delaware General Corporation Law.

limited solely to the voting of the Shares with respect to the matters described in Section 1(a)(i) and Section 1(a)(ii) and shall automatically terminate upon the termination of this Agreement.

Section 2. Transfer of Shares.

(a) Each Stockholder covenants and agrees that such Stockholder shall not directly or indirectly (i) make any Transfer of any of the Shares, (ii) deposit any of the Shares into a voting trust or enter into a voting agreement or arrangement with respect to the Shares or grant any proxy or power of attorney with respect thereto which is inconsistent with this Agreement, or (iii) enter into any contract, option or other arrangement or undertaking with respect to the Transfer of any Shares; provided, however, that nothing in this Agreement shall prohibit (A) any Stockholder from exercising options to purchase shares of Company Common Stock (including by paying the exercise price of such options by “net exercise” by the delivery of shares of Company Common Stock if and to the extent permitted by, and in accordance with, the terms of the stock option plan and agreement applicable thereof), (B) the Transfer of Shares pursuant to the laws of testamentary or intestate succession or otherwise involuntarily transferred by operation of law, and (C) any Transfer of Shares whereby each Person to which any of such Shares, or any interest in any of such Shares, is or may be transferred shall have: (I) executed a counterpart of this Agreement as a “Stockholder”, and (II) agreed in writing to hold such Shares (or interest in such Shares) subject to and in compliance with all of the terms and provisions of this Agreement applicable to “Stockholders.”

(b) Each Stockholder agrees to submit to the Company contemporaneously with or promptly following execution of this Agreement all certificates representing the Shares so that the Company may place thereon a conspicuous legend referring to the transfer restrictions set forth in this Agreement.

(c) For purposes of this Agreement, “Transfer” means, with respect to any security, (i) the direct or indirect sale, assignment, transfer, tender, pledge, hypothecation, gift, placement in trust, or other disposition of such security (including transfers by merger, testamentary or intestate succession, interspousal disposition pursuant to a domestic relations proceeding or otherwise by operation of law) or any right, title or interest therein (including, but not limited to, any right or power to vote to which the holder thereof may be entitled, whether such right or power is granted by proxy or otherwise), or the record or beneficial ownership (as determined pursuant to Rule 13d-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) thereof, (ii) the offer to make such a sale, assignment, transfer, tender, pledge, hypothecation, gift, placement in trust or other disposition, and (iii) each agreement, arrangement or understanding, whether or not in writing, to effect any of the foregoing actions or transactions.

Section 3. Representations and Warranties of the Stockholders. Each Stockholder on its own behalf hereby severally represents and warrants to the Buyer with respect to itself and its, his or her ownership of the Shares as follows:

(a) Ownership of Shares. The Stockholder beneficially owns all of the Shares as set forth on Schedule I hereto and has good and marketable title to such Shares, free and clear of any claims, liens, encumbrances and security interests whatsoever. The Stockholder owns no shares of Company Common Stock other than the Shares as set forth on Schedule I hereto. The Stockholder has sole voting power, without restrictions, with respect to all of the Shares.

(b) Power, Binding Agreement. The Stockholder has the legal capacity and all requisite power and authority to enter into and perform all of its obligations, under this Agreement. This Agreement has been duly and validly executed and delivered by the Stockholder and constitutes a valid and binding obligation of the Stockholder, enforceable against the Stockholder in accordance with its terms, subject only to the effect, if any, of (a) applicable bankruptcy, insolvency, fraudulent conveyance, moratorium and similar laws affecting creditors’ rights and remedies generally and (b) general principles of equity.

(c) No Conflicts. The execution and delivery of this Agreement do not, and the consummation of the transactions contemplated hereby will not, conflict with or result in any violation of, or default (with or without notice or lapse of time, or both) under, or give rise to a right of termination, cancellation or

B-2

EXECUTION COPY

acceleration of any obligation or to loss of a material benefit under, any provision of any loan or credit agreement, note, bond, mortgage, indenture, lease, or other agreement, instrument, permit, concession, franchise, license, judgment, order, decree, statute, law, ordinance, rule or regulation applicable to the Stockholder, the Shares or any of the Stockholder’s properties or assets. Except as expressly contemplated hereby, the Stockholder is not a party to, and the Shares are not subject to or bound in any manner by, any contract or agreement relating to the Shares, including without limitation, any voting agreement, option agreement, purchase agreement, stockholders’ agreement, partnership agreement or voting trust. No consent, approval, order or authorization of, or registration, declaration or filing with, any court, administrative agency or commission or other governmental authority or instrumentality, domestic, foreign or supranational, is required by or with respect to the Stockholder in connection with the execution and delivery of this Agreement or the consummation by the Stockholder of the transactions contemplated hereby.

Section 4. No Ownership Interest. Nothing contained in this Agreement shall be deemed to vest in the Buyer or any of its Subsidiaries any direct or indirect ownership or incidents of ownership of or with respect to any Shares (other than “beneficial ownership” as such term is defined in Rule 13d-3 under the Exchange Act, and then only to the extent of the voting power conferred by the proxy granted hereby). Except as expressly set forth herein, all rights, ownership and economic benefits of and relating to the Shares shall remain vested in and belong to the Stockholder, and neither the Buyer nor or any of its Subsidiaries shall have any authority to manage, direct, superintend, restrict, regulate, govern, or administer any of the policies or operations of the Company or exercise any power or authority to direct the Stockholder in the voting of any of the Shares, except as otherwise provided herein or in the Merger Agreement.

Section 5. Termination. This Agreement shall terminate upon the earlier to occur of (a) the Effective Time or (b) any termination of the Merger Agreement in accordance with the terms thereof; provided that no such termination shall relieve any party of liability for a willful breach hereof prior to termination, and provided further, that the termination of this Agreement will not affect any rights hereunder which by their terms do not terminate or expire prior to or at such termination.

Section 6. Specific Performance. The parties hereto agree that irreparable damage would occur in the event any provision of this Agreement was not performed in accordance with the terms hereof and that the parties shall be entitled to specific performance of the terms hereof, in addition to any other remedy at law or in equity.

Section 7. Fiduciary Duties. Each Stockholder is signing this Agreement solely in such Stockholder’s capacity as an owner of his, her or its respective Shares, and nothing herein shall prohibit, prevent or preclude such Stockholder from taking or not taking any action in his or her capacity as an officer or director of the Company, to the extent permitted by the Merger Agreement.

Section 8. Consent and Waiver; Transfer of Subsidiary Shares. Each Stockholder hereby gives any consents or waivers that are reasonably required for the consummation of the Merger under the terms of any agreement to which such Stockholder is a party or pursuant to any rights such Stockholder may have in its capacity as a Stockholder of the Company. Each Stockholder who is the holder (whether of record, in trust, as nominee or otherwise) of any shares of stock of any Subsidiary of the Company hereby covenants and agrees, forthwith upon written request by the Buyer, to sell, assign, transfer and deliver to such person as may be designated by the Buyer, effective as of the Effective Time (or such later time as may be designated by the Buyer), all such shares of stock of each such Subsidiary of the Company, and to execute and deliver such certificates and instruments as may reasonably be requested by the Buyer to effect and confirm such sale, transfer, assignment and delivery.

Section 9. Miscellaneous.

(a) Entire Agreement. This Agreement constitutes the entire agreement between the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and understandings, both written

B-3

EXECUTION COPY

and oral, between the parties with respect thereto. This Agreement may not be amended, modified or rescinded except by an instrument in writing signed by each of the parties hereto.

(b) Severability. If any term or other provision of this Agreement is invalid, illegal or incapable of being enforced by any rule of law, or public policy, all other conditions and provisions of this Agreement shall nevertheless remain in full force and effect. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible to the fullest extent permitted by applicable law in a mutually acceptable manner in order that the terms of this Agreement remain as originally contemplated to the fullest extent possible.

(c) Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware without regard to the principles of conflicts of law thereof.

(d) Counterparts; Effectiveness. This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which together shall constitute one and the same instrument. This Agreement shall become effective and enforceable against an executing Stockholder when executed and delivered by such Stockholder and the Buyer, whether or not this Agreement has been (or is ever) executed and delivered by any other Stockholder or Stockholders, and the enforceability of this Agreement against such executing Stockholder shall not be affected by the failure of any other Stockholder or Stockholders to execute and deliver this Agreement or by the invalidity or unenforceability of this Agreement as against any other Stockholder or Stockholders.

(e) Amendment; Waiver. This Agreement may be amended by the parties hereto only by an instrument in writing signed on behalf of the parties hereto; provided, however, that this Agreement may be amended to add permitted transferees as parties in accordance with the provisions of Section 2(a) by the execution and delivery of a signature page by such permitted transferee to the Buyer, without action by any other party; and provided further, that this Agreement may be amended as to any particular Stockholder by the execution and deliver of an amendment by such Stockholder and the Buyer, without action by any other Stockholder. The performance of any provision of this Agreement may be waived and the time for such performance may be extended, but no such waiver or extension shall be valid unless set forth in a written instrument signed by or on behalf of the party receiving or intended to receive the benefit of such performance. The failure of any party to this Agreement to assert any of its rights under this Agreement or otherwise shall not constitute a waiver of such rights.

(f) Notices. All notices and other communications hereunder shall be in writing and shall be deemed duly delivered (i) three business days after being sent by registered or certified mail, return receipt requested, postage prepaid, or (ii) one business day after being sent for next business day delivery, fees prepaid, via a reputable nationwide overnight courier service, in each case to the intended recipient as set forth below:

Annex C

NON-COMPETITION, NON-SOLICITATION AND CONFIDENTIALITY
AGREEMENT

THIS NON-COMPETITION, NON-SOLICITATION AND CONFIDENTIALITY AGREEMENT (the ‘‘Agreement”), dated as of May 26, 2011, is made by and between Skyworks Solutions, Inc., a Delaware corporation (“Buyer”), and Richard K. Williams, an individual residing in the State of California (the “Stockholder”). The Buyer and the Stockholder are each referred to in this Agreement as a “Party” and collectively as the “Parties.”

RECITALS

A. The Buyer, PowerCo Acquisition Corp., a Delaware corporation (the “Merger Sub”), and Advanced Analogic Technologies, Inc., a Delaware corporation (the “Company”) have entered into an Agreement and Plan of Merger, dated as of May 26, 2011 (the “Merger Agreement”), pursuant to which the Buyer will acquire the Company through a merger of Merger Sub with and into the Company. After giving effect to the Merger, the Company will be a wholly-owned subsidiary of the Buyer (the “Merger”).

B. The Company is engaged, either directly or through subsidiaries, in the business of developing, designing, manufacturing, licensing, marketing, selling and distributing power management semiconductors and related software (the “Business”). (For the purpose of clarity: The Company does not engage in business, applications or software unrelated to power management semiconductors (such as microprocessors, digital memory, discrete sensors and biotech). It also does not engage in devices and circuits used in motor drive.)

C. The parties acknowledge that the relevant market for the Business is worldwide in scope and that intense worldwide competition exists for the products and services of the Business.

D. The Stockholder has a substantial equity interest in the Company and will receive significant cash and stock proceeds and other valuable consideration as a result of the Merger. The Stockholder is a member of the Company’s board of directors, an executive officer of the Company and one of the Company’s key employees, and acknowledges that he has detailed knowledge of competitively sensitive and important Confidential Information and trade secrets of the Company, including information regarding the Company’s plans and relationships with customers, suppliers and others. The Stockholder recognizes the Buyer’s interest, as a purchaser of the Company, in protecting, among other things, the relationships that the Company and its subsidiaries have with customers and suppliers and the goodwill associated with their ongoing business.

E. The Parties agree that it is their mutual desire that the entire goodwill of the Company and its business be transferred to the Buyer as part of the Merger, and they acknowledge that they explicitly considered the value of the goodwill to be transferred in the Merger, and that such goodwill was valued as a component of the consideration to be paid by the Buyer in and for the Merger. The Parties further agree that the Buyer’s failure to receive the entire goodwill contemplated by the Merger would have affected the Buyer’s willingness to enter into the Merger Agreement or reduced the value of the Merger and the Company to the Buyer and the price the Buyer was willing to pay to acquire the Company.

F. The Stockholder acknowledges and agrees that it is his intention to transfer the goodwill reflected in the capital stock of the Company that he owns and that the Stockholder has a material economic interest in the consummation of the Merger. The Stockholder has considered the effects of this Agreement, considers them reasonable and, in order to induce the Buyer to enter into the Merger Agreement and consummate the Merger, the Stockholder has agreed to enter into and be bound by this Agreement.

Accordingly, the Parties are executing and delivering this Agreement contemporaneously with the execution and delivery of the Merger Agreement, and that the continued effectiveness of this Agreement is a condition to the Buyer’s obligations to consummate the Merger.

C-1

EXECUTION COPY

NOW, THEREFORE, in consideration of the premises, the mutual covenants and agreements set forth herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Buyer and the Stockholder, for themselves and their successors and assigns, and intending to be legally bound, hereby agree as follows:

AGREEMENTS

1. Definitions. As used in this Agreement, the following terms shall have the following respective meanings.

(a) ‘‘Affiliate” of a Person means any other Person that directly or indirectly through one or more intermediaries, controls, is controlled by or is under common control with the first Person. For purposes of this definition, “control” of a Person shall mean the possession, directly or indirectly, of the power to direct or cause the direction of the management policies of a Person, whether through the ownership of voting securities, (including, but not limited to, the ownership of ten percent (10%) or more of the voting securities of the Person), by contract, as trustee or executor or otherwise.

(b) ‘‘Company Customer” means (i) any Person to whom or which the Company or any of its subsidiaries is currently selling products or providing services or with whom or which the Company or any of its subsidiaries currently has a signed agreement to sell products or provide services, (ii) any Person to whom or which the Company or any of its subsidiaries sold products, provided services or signed an agreement to sell products or provide services during the twenty-four (24) month period immediately preceding the Effective Time, (iii) any Person to whom or which the Company or any of its subsidiaries has contacted, solicited or provided a proposal for services, or any Person who has contacted or solicited the Company or any of its subsidiaries regarding products or services of the Company or any of its subsidiaries, during the twenty-four (24) month period immediately preceding the Effective Time, (iv) any Person whom the Stockholder knows or has reason to know the Company or any of its subsidiaries currently plans to solicit as a client for its products or services, or future products or services, or (v) any Affiliate of any Person described in clauses (i) through (iv) above.

(c) ‘‘Confidential Information” means any and all confidential and proprietary information pertaining to the Company or any of its subsidiaries, such as proposals, plans, inventions, practices, systems, programs, subscriptions, strategies, formulas, processes, methods, techniques, research, records, suppliers, sources, customer lists, billing information, other forms of business information, and trade secrets of every kind and character, whether or not they constitute a trade secret under applicable law. The term Confidential Information shall not include any information in the public domain or information that is rightfully in the possession of a third party and is not subject to a confidentiality obligation, provided that such information has not entered the public domain or come into possession of a third party due to the violation of any contractual, fiduciary or other legal obligation of the Stockholder or any other person or entity.

(d) ‘‘Person” means an individual, corporation, limited liability company, partnership, limited partnership, association, estate, trust, unincorporated organization, governmental entity or authority (including, but not limited to, any municipal, county or state entity, board, authority, agency or similar organization), or any other entity or organization.

(e) ‘‘Restricted Period” means the period from and after the date hereof and continuing until the twenty-four (24) month anniversary of the Effective Time (as such term is defined in the Merger Agreement) of the Merger.

2. Non-Competition. As an inducement for the Buyer to enter into the Merger Agreement and to consummate the Merger, and in connection with the sale of the Stockholder’s equity interest in the Company pursuant to the Merger, the Stockholder agrees that during the Restricted Period, the Stockholder shall not, anywhere in the world, directly or indirectly engage, without the express prior written consent of the Buyer after the date hereof, in any business or activity in competition with the Business, whether as an employee, consultant, partner, principal, agent, representative, equity holder or in any other individual, corporate or

C-2

EXECUTION COPY

representative capacity (without limitation by specific enumeration of the foregoing), or render any services or provide any advice to any Person in competition (or seeking to compete, directly or indirectly) with the Business (a “Competing Business”). Nothing in this Section 2 shall prohibit the Stockholder from (i) acquiring up to two percent (2%) of any class of outstanding equity security of any competing business whose equity securities are regularly traded on a national securities exchange or The Nasdaq Market, (ii) making or holding a passive investment in a venture fund, angel fund, or similar investment vehicle that invests in a competing business representing less than two percent (2%) of the total investment of such venture fund, angel fund, or similar investment or (iii) making or holding a passive investment in a private company engaged in a competing business representing less than two percent (2%) of the total investment of such private company; provided, that if the Stockholder is then an employee of the Buyer, the Company or any of their respective subsidiaries, such investment shall be permitted only if (i) such investment does not interfere with the Stockholder’s duties and obligations to the Buyer, the Company and their respective subsidiaries, as determined in good faith by the Board of Directors of the Company (prior to the Effective Time) or the Buyer (following the Effective Time) in its sole discretion and (ii) such shares shall not constitute more than five percent (5%) of the Stockholder’s net worth.

3. Non-Solicitation of Employees. During the Restricted Period:

(a) The Stockholder shall not directly or indirectly solicit (or assist, participate in or promote the solicitation of) any individual who is then employed by the Buyer, the Company or any of their respective direct or indirect subsidiaries to leave such employment. The Parties hereto agree that the placing of general advertisements in newspapers, magazines or electronic media, or other communication targeted to a generalized audience, in either case which are not specifically aimed at the Buyer, the Company, or any of their respective direct or indirect subsidiaries shall not, in itself, constitute a breach of this Section 3.

(b) The Stockholder shall not disclose any intent that he may form to terminate his employment with the Buyer, the Company or any of their respective direct or indirect subsidiaries to any employee of the Buyer, the Company or any of their respective subsidiaries prior to the earliest to occur of either the date on which such employment terminates or the date on which the Buyer or the Company provides notice to employees generally of such termination.

(c) If a former employee of the Company or any of its subsidiaries contacts the Stockholder about (i) any business matter involving the Buyer, the Company or any of their respective subsidiaries, or (ii) any matter involving the former employee’s new business (including, but not limited to, prospective employment with such new business), the Stockholder shall inform the former employee that he cannot discuss the matter further.

4. Non-Solicitation of Company Customers. During the Restricted Period:

(a) The Stockholder shall not directly or indirectly solicit, divert or take away, or assist in or attempt to solicit, divert or take away, the business or patronage of any Company Customer.

(b) If a Company Customer contacts the Stockholder concerning the possibility of a discontinuation or reduction of the Company Customer’s business with the Buyer, the Company or any of their respective subsidiaries, the Stockholder shall inform such Company Customer that he cannot discuss the matter further without informing the Buyer and the Company.

(c) The Stockholder shall not disclose any intent that he may form to terminate his employment with the Buyer, the Company or any of their respective subsidiaries to any Company Customer prior to the termination of such employment or the date, if earlier, on which the Buyer or the Company publicly discloses such termination.

5. Confidentiality.

(a) The Stockholder acknowledges that Confidential Information has been and will continue to be of central importance to the business of the Company and its subsidiaries and that disclosure of it to or its use by

C-3

EXECUTION COPY

others could cause substantial loss to the Company and its subsidiaries and, following the Effective Time, to the Buyer and its subsidiaries. Accordingly, from and after the date of this Agreement, the Stockholder shall maintain the confidentiality of all Confidential Information and shall not use or disclose any Confidential Information to any Person, for any reason or purpose, except (i) as reasonably required to perform his duties to the Company and its subsidiaries as a director, officer and/or employee thereof (or his duties to the Buyer and its subsidiaries, as the case may be, following the Effective Time), and for their sole benefit, or (ii) as required by law as described in Section 5(c) below.

(b) The obligations contained in Section 5(a) shall not apply to any information which has: (i) become publicly known and made generally available through no wrongful act of the Stockholder or of others who were under confidentiality obligations as to the item or items involved, or (ii) been independently acquired or developed by the Stockholder outside the scope of his duties at the Company and its subsidiaries or any predecessor of the Company.

(c) If the Stockholder becomes legally obligated (by deposition, interrogatory, request for documents, subpoena, civil investigation, demand or similar process) to disclose any Confidential Information, the Stockholder shall provide the Buyer and the Company with prompt written notice of such requirement so that the Buyer or the Company, as the case may be, may seek a protective order or other appropriate relief. If a protective order or other remedy is not obtained by the Buyer or the Company, the Stockholder may furnish only that portion of Confidential Information which is required pursuant to the legal process, and (at the Buyer’s or the Company’s expense, as the case may be) shall exercise reasonable efforts to obtain reliable assurances that confidential treatment will be accorded such Confidential Information. If either during or after his employment with the Buyer, the Company or any of their respective subsidiaries, the Stockholder receives a subpoena or other inquiry related to a regulatory, civil or criminal proceeding concerning any matter which may involve the Buyer, the Company or any of their respective subsidiaries, whether or not such matter could result in the Stockholder having to disclose any Confidential Information, the Stockholder shall give prompt notice to the Buyer or the Company, as the case may be, of the subpoena or inquiry and the matter covered thereby and any information which the Stockholder is required to produce in connection therewith.

6. Equitable Remedies. The Buyer and the Stockholder confirm that the restrictions contained in this Agreement are, in view of the nature of the business of the Company, reasonable and necessary to protect the legitimate interests of the Buyer and that any breach of any material provision in this Agreement will result in irreparable injury to the Buyer. Therefore, the Stockholder hereby agrees that, in the event of any breach or threatened breach of any material term or condition of this Agreement by the Stockholder, the Buyer’s remedies at law will be inadequate and, in any such event, the Buyer shall be entitled to commence an action for preliminary and permanent injunctive relief and other equitable and monetary relief (including attorneys’ fees) in any court of competent jurisdiction, and that if such relief is granted the Buyer shall not be required to post any bond.

7. Miscellaneous.

7.1 Governing Law. This Agreement shall be interpreted and enforced pursuant to the laws of the State of California, without giving any effect to the conflict of laws rules or principles of any jurisdiction.

7.2 Dispute Resolution; Waiver of Jury Trial.

(a) All disputes, claims or controversies arising out of or in connection with this Agreement shall be subject to the jurisdiction of the courts of the State of California located in Santa Clara County, California and the United States District Court for the Northern District of California, and each of the Company and the Stockholder hereby waives any objection to the laying of venue in any such court. Notwithstanding the previous sentence and provided both Parties consent, the Parties may, at any time after the inception of a dispute, claim or controversy arising out of or in connection with this Agreement, submit such dispute, claim or controversy to binding arbitration under the rules of the American Arbitration Association in effect at the inception of such dispute, claim or controversy. The Parties shall cooperate fully with each other so that any

C-4

EXECUTION COPY

such dispute, claim or controversy submitted to binding arbitration pursuant to this Section 7.2 may be resolved as expeditiously as possible.

(b) The prevailing Party in a proceeding commenced with respect to any dispute, claim or controversy arising out of or in connection with this Agreement shall be entitled to recover, in addition to any other relief awarded, its reasonable costs and expenses, including attorneys’ and expert witness fees and disbursements, of preparing for and participating in any such proceeding.

(c) The Buyer and the Stockholder each hereby waives the right to trial by jury in all proceedings commenced with respect to any disputes, claims or controversies arising out of or in connection with this Agreement.

7.4 Assignment. This Agreement shall be binding upon and inure to the benefit of the executors, administrators, heirs, successors, and assigns of the Parties; provided, however, that this Agreement shall not be assignable by the Stockholder. The Stockholder agrees that, upon request therefor, he will, in writing, acknowledge and consent to any such assignment of this Agreement.

7.5 Waiver. Failure or delay on the part of either Party hereto to enforce any right, power or privilege hereunder shall not be deemed to constitute a waiver thereof. A waiver by one Party of a breach of any promise by the other Party contained herein shall not operate as or be construed to constitute a waiver of any subsequent breach of such promise by such other Party.

7.6 Headings. The headings of the sections and paragraphs contained in this Agreement are for reference purposes only and shall not in any way affect the meaning or interpretation of any provision of this Agreement.

7.7 Construction. The language used in this Agreement shall be deemed to be the language chosen by the Parties hereto to express their mutual intent, and no rule of strict construction, for or against either Party, shall be applied. Capitalized terms used in this Agreement without definition shall have the respective meaning ascribed to them in the Merger Agreement.

7.8 Counterparts. This Agreement may be executed in counterparts, none of which need contain the signature of more than one Party hereto, each of which shall be deemed to be an original, and all of which together shall constitute a single agreement.

C-5

EXECUTION COPY

nothing herein supersedes the Stockholder Agreement of even date herewith to which the Stockholder is a party.

7.10 Effect. This Agreement shall be effective from and after the date first written above upon execution and delivery by the Parties; provided, however, that if the Merger is not consummated and the Merger Agreement is terminated, this Agreement shall automatically terminate concurrently with the termination of the Merger Agreement and shall be of no further force or effect.

Santa Clara, CA 95054

Gentlemen:

We understand that Skyworks Solutions, Inc. (“Parent”), Advanced Analogic Technologies Incorporated (the “Company”), and PowerCo Acquisition Corp., a wholly-owned subsidiary of Parent (“Merger Sub”) propose to enter into an Agreement and Plan of Merger (the “Merger Agreement”) whereby, upon the terms and subject to the conditions set forth in the Merger Agreement, Merger Sub will be merged with and into the Company and the Company will continue as a wholly-owned subsidiary of Parent (the “Merger”). The terms and conditions of the Merger will be set forth more fully in the Merger Agreement.

Pursuant to the proposed Merger Agreement, we understand that, at the Effective Time (as defined in the Merger Agreement), each issued and outstanding share of common stock, $0.001 par value per share, of the Company (“Company Common Stock”) (other than shares owned by Parent, the Company or any wholly owned subsidiary of Parent or the Company, and other than dissenting shares) will be converted into the right to receive $3.68 in cash (as the same may be adjusted in accordance with the Merger Agreement, the “Cash Amount”) and 0.08725 of a share of common stock, $0.25 par value per share, of Parent (“Parent Common Stock”) (the “Stock Amount” and, together with the Cash Amount, the “Consideration”); provided, however, that if the product of the Stock Amount and the average last reported sale price of Parent Common Stock on the five full trading days ending on the trading day immediately prior to the date on which the Effective Time occurs (such average, the “Average Price,” and such product, the “Closing Value”) is less than $2.45, then the Cash Amount shall be increased by the difference between the $2.45 and the Closing Value and if the Closing Value is more than $2.45, then the Cash Amount shall be reduced by the difference between the Closing Value and $2.45 (but in no event shall the Cash Amount be less than $0.00); and provided, further, that if the Average Price is less than $21.00, then Parent shall have the right to pay the entire Consideration in cash, and in such case the Cash Amount will be $6.13 and the Stock Amount will be zero.

You have asked us to advise you as to the fairness, from a financial point of view, to the holders of Company Common Stock of the Consideration to be received by such holders pursuant to the Merger Agreement.

For purposes of this opinion we have, among other things: (i) reviewed the execution copy of the Merger Agreement; (ii) reviewed certain publicly available information concerning Parent and the Company and certain other relevant financial and operating data of Parent and the Company furnished to us by Parent and the Company; (iii) reviewed the historical stock prices and trading volumes of Parent Common Stock and Company Common Stock; (iv) held discussions with members of management of Parent and the Company concerning the current operations of and future business prospects for Parent and the Company and joint prospects for the combined companies; (v) reviewed certain financial forecasts with respect to the Company prepared by the management of the Company and held discussions with members of such management concerning those forecasts; (vi) reviewed certain research analyst projections with respect to Parent and held discussions with members of the management of Parent concerning those projections; (vii) compared certain publicly available financial data of companies whose securities are traded in the public markets and that we deemed generally relevant to similar data for Parent and the Company; (viii) reviewed the financial terms of certain other business combinations that we deemed generally relevant; and (ix) reviewed such other financial studies and analyses and considered such other matters as we have deemed appropriate.

In connection with our review and in arriving at our opinion, we have assumed and relied on the accuracy and completeness of all of the financial, accounting, legal, tax and other information discussed with or reviewed by us for purposes of this opinion and have neither attempted to verify independently nor assumed responsibility for verifying any of such information. We have assumed the accuracy of the representations and warranties contained in the Merger Agreement and all agreements related thereto. In addition, we have assumed, with your consent, that the Merger will be consummated upon the terms and subject to the conditions set forth in the execution copy of the Merger Agreement without waiver, modification or amendment of any material term, condition or agreement thereof and that, in the course of obtaining the necessary regulatory or third party approvals, consents and releases for the Merger, no delay, limitation, restriction or condition will be imposed that would have an adverse effect on Parent, the Company or the contemplated benefits of the Merger. With respect to the financial forecasts for the Company provided to us by management of the Company, we have assumed, with your consent and based upon discussions with such management, that such forecasts have been reasonably prepared on bases reflecting the best currently available estimates and judgments of such management, at the time of preparation, of the future operating and financial performance of the Company. With respect to the research analyst projections for Parent, we have assumed, with your consent and based upon discussions with management of Parent, that such projections represent reasonable estimates as to the future financial performance of Parent.

We have not assumed any responsibility for or made or obtained any independent evaluation, appraisal or physical inspection of the assets or liabilities of Parent or the Company nor have we evaluated the solvency or fair value of Parent or the Company under any state or federal laws relating to bankruptcy, insolvency or similar matters. Further, our opinion is based on economic, monetary and market conditions as they exist and can be evaluated as of the date hereof and we assume no responsibility to update or revise our opinion based upon circumstances and events occurring after the date hereof. Our opinion as expressed herein is limited to the fairness, from a financial point of view, to the holders of Company Common Stock of the Consideration to be received by such holders pursuant to the Merger Agreement and we express no opinion as to the fairness of the Merger to, or any consideration received in connection therewith by, the holders of any other class of securities, creditors or other constituencies of the Company, or as to the Company’s underlying business decision to engage in the Merger or the relative merits of the Merger as compared to other business strategies that might be available to the Company. In addition, we express no opinion with respect to the amount or nature or any other aspect of any compensation payable to or to be received by any officers, directors or employees of any party to the Merger, or any class of such persons, relative to the Consideration to be received pursuant to the Merger Agreement or with respect to the fairness of any such compensation. Our opinion does not constitute a recommendation to any stockholder of the Company as to how such stockholder should vote with respect to the proposed Merger.

We are not expressing any opinion as to the value of Parent Common Stock if and when issued pursuant to the Merger or the prices at which Parent Common Stock or Company Common Stock will actually trade at any time.

We have been engaged by the Company as financial advisor in connection with the Merger and to render this opinion and will receive fees for our services, a portion of which is payable upon rendering this opinion and a substantial portion of which is contingent on the consummation of the Merger. In addition, the Company has agreed to indemnify us for certain liabilities arising out of our role as financial advisor and out of the rendering of this opinion and to reimburse us for our out-of-pocket expenses. We have not in the past two years provided investment banking or financial advisory services to the Company unrelated to the proposed Merger and have not in the past two years provided investment banking or financial advisory services to Parent. We may in the future provide investment banking and financial advisory services to Parent, the Company and their respective affiliates unrelated to the proposed Merger, for which services we would expect to receive compensation. In the ordinary course of our business, we may actively trade the equity securities of Parent and the Company for our own account or for the accounts of customers or affiliates and, accordingly, may at any time hold a long or short position in such securities.

Annex E

Section 262 of the Delaware General Corporation Law

§ 262. Appraisal rights

(a) Any stockholder of a corporation of this State who holds shares of stock on the date of the making of a demand pursuant to subsection (d) of this section with respect to such shares, who continuously holds such shares through the effective date of the merger or consolidation, who has otherwise complied with subsection (d) of this section and who has neither voted in favor of the merger or consolidation nor consented thereto in writing pursuant to § 228 of this title shall be entitled to an appraisal by the Court of Chancery of the fair value of the stockholder’s shares of stock under the circumstances described in subsections (b) and (c) of this section. As used in this section, the word “stockholder” means a holder of record of stock in a corporation; the words “stock” and “share” mean and include what is ordinarily meant by those words; and the words “depository receipt” mean a receipt or other instrument issued by a depository representing an interest in 1 or more shares, or fractions thereof, solely of stock of a corporation, which stock is deposited with the depository.

(b) Appraisal rights shall be available for the shares of any class or series of stock of a constituent corporation in a merger or consolidation to be effected pursuant to § 251 (other than a merger effected pursuant to § 251(g) of this title), § 252, § 254, § 255, § 256, § 257, § 258, § 263 or § 264 of this title:

(1) Provided, however, that no appraisal rights under this section shall be available for the shares of any class or series of stock, which stock, or depository receipts in respect thereof, at the record date fixed to determine the stockholders entitled to receive notice of the meeting of stockholders to act upon the agreement of merger or consolidation, were either (i) listed on a national securities exchange or (ii) held of record by more than 2,000 holders; and further provided that no appraisal rights shall be available for any shares of stock of the constituent corporation surviving a merger if the merger did not require for its approval the vote of the stockholders of the surviving corporation as provided in § 251(f) of this title.

(2) Notwithstanding paragraph (1) of this subsection, appraisal rights under this section shall be available for the shares of any class or series of stock of a constituent corporation if the holders thereof are required by the terms of an agreement of merger or consolidation pursuant to §§ 251, 252,254, 255, 256, 257, 258, 263 and 264 of this title to accept for such stock anything except:

a. Shares of stock of the corporation surviving or resulting from such merger or consolidation, or depository receipts in respect thereof;

b. Shares of stock of any other corporation, or depository receipts in respect thereof, which shares of stock (or depository receipts in respect thereof) or depository receipts at the effective date of the merger or consolidation will be either listed on a national securities exchange or held of record by more than 2,000 holders;

c. Cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a. and b. of this paragraph;

d. Any combination of the shares of stock, depository receipts and cash in lieu of fractional shares or fractional depository receipts described in the foregoing subparagraphs a., b. and c. of this paragraph.

(3) In the event all of the stock of a subsidiary Delaware corporation party to a merger effected under § 253 or § 267 of this title is not owned by the parent immediately prior to the merger, appraisal rights shall be available for the shares of the subsidiary Delaware corporation.

(c) Any corporation may provide in its certificate of incorporation that appraisal rights under this section shall be available for the shares of any class or series of its stock as a result of an amendment to its certificate

E-1

of incorporation, any merger or consolidation in which the corporation is a constituent corporation or the sale of all or substantially all of the assets of the corporation. If the certificate of incorporation contains such a provision, the procedures of this section, including those set forth in subsections (d) and (e) of this section, shall apply as nearly as is practicable.

(d) Appraisal rights shall be perfected as follows:

(1) If a proposed merger or consolidation for which appraisal rights are provided under this section is to be submitted for approval at a meeting of stockholders, the corporation, not less than 20 days prior to the meeting, shall notify each of its stockholders who was such on the record date for notice of such meeting (or such members who received notice in accordance with § 255(c) of this title) with respect to shares for which appraisal rights are available pursuant to subsection (b) or (c) of this section that appraisal rights are available for any or all of the shares of the constituent corporations, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Each stockholder electing to demand the appraisal of such stockholder’s shares shall deliver to the corporation, before the taking of the vote on the merger or consolidation, a written demand for appraisal of such stockholder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such stockholder’s shares. A proxy or vote against the merger or consolidation shall not constitute such a demand. A stockholder electing to take such action must do so by a separate written demand as herein provided. Within 10 days after the effective date of such merger or consolidation, the surviving or resulting corporation shall notify each stockholder of each constituent corporation who has complied with this subsection and has not voted in favor of or consented to the merger or consolidation of the date that the merger or consolidation has become effective; or

(2) If the merger or consolidation was approved pursuant to § 228, § 253, or § 267 of this title, then either a constituent corporation before the effective date of the merger or consolidation or the surviving or resulting corporation within 10 days thereafter shall notify each of the holders of any class or series of stock of such constituent corporation who are entitled to appraisal rights of the approval of the merger or consolidation and that appraisal rights are available for any or all shares of such class or series of stock of such constituent corporation, and shall include in such notice a copy of this section and, if 1 of the constituent corporations is a nonstock corporation, a copy of § 114 of this title. Such notice may, and, if given on or after the effective date of the merger or consolidation, shall, also notify such stockholders of the effective date of the merger or consolidation. Any stockholder entitled to appraisal rights may, within 20 days after the date of mailing of such notice, demand in writing from the surviving or resulting corporation the appraisal of such holder’s shares. Such demand will be sufficient if it reasonably informs the corporation of the identity of the stockholder and that the stockholder intends thereby to demand the appraisal of such holder’s shares. If such notice did not notify stockholders of the effective date of the merger or consolidation, either (i) each such constituent corporation shall send a second notice before the effective date of the merger or consolidation notifying each of the holders of any class or series of stock of such constituent corporation that are entitled to appraisal rights of the effective date of the merger or consolidation or (ii) the surviving or resulting corporation shall send such a second notice to all such holders on or within 10 days after such effective date; provided, however, that if such second notice is sent more than 20 days following the sending of the first notice, such second notice need only be sent to each stockholder who is entitled to appraisal rights and who has demanded appraisal of such holder’s shares in accordance with this subsection. An affidavit of the secretary or assistant secretary or of the transfer agent of the corporation that is required to give either notice that such notice has been given shall, in the absence of fraud, be prima facie evidence of the facts stated therein. For purposes of determining the stockholders entitled to receive either notice, each constituent corporation may fix, in advance, a record date that shall be not more than 10 days prior to the date the notice is given, provided, that if the notice is given on or after the effective date of the merger or consolidation, the record date shall be such effective date. If no record date is fixed and the notice is given prior to the effective date, the record date shall be the close of business on the day next preceding the day on which the notice is given.

E-2

(e) Within 120 days after the effective date of the merger or consolidation, the surviving or resulting corporation or any stockholder who has complied with subsections (a) and (d) of this section hereof and who is otherwise entitled to appraisal rights, may commence an appraisal proceeding by filing a petition in the Court of Chancery demanding a determination of the value of the stock of all such stockholders. Notwithstanding the foregoing, at any time within 60 days after the effective date of the merger or consolidation, any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party shall have the right to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation. Within 120 days after the effective date of the merger or consolidation, any stockholder who has complied with the requirements of subsections (a) and (d) of this section hereof, upon written request, shall be entitled to receive from the corporation surviving the merger or resulting from the consolidation a statement setting forth the aggregate number of shares not voted in favor of the merger or consolidation and with respect to which demands for appraisal have been received and the aggregate number of holders of such shares. Such written statement shall be mailed to the stockholder within 10 days after such stockholder’s written request for such a statement is received by the surviving or resulting corporation or within 10 days after expiration of the period for delivery of demands for appraisal under subsection (d) of this section hereof, whichever is later. Notwithstanding subsection (a) of this section, a person who is the beneficial owner of shares of such stock held either in a voting trust or by a nominee on behalf of such person may, in such person’s own name, file a petition or request from the corporation the statement described in this subsection.

(f) Upon the filing of any such petition by a stockholder, service of a copy thereof shall be made upon the surviving or resulting corporation, which shall within 20 days after such service file in the office of the Register in Chancery in which the petition was filed a duly verified list containing the names and addresses of all stockholders who have demanded payment for their shares and with whom agreements as to the value of their shares have not been reached by the surviving or resulting corporation. If the petition shall be filed by the surviving or resulting corporation, the petition shall be accompanied by such a duly verified list. The Register in Chancery, if so ordered by the Court, shall give notice of the time and place fixed for the hearing of such petition by registered or certified mail to the surviving or resulting corporation and to the stockholders shown on the list at the addresses therein stated. Such notice shall also be given by 1 or more publications at least 1 week before the day of the hearing, in a newspaper of general circulation published in the City of Wilmington, Delaware or such publication as the Court deems advisable. The forms of the notices by mail and by publication shall be approved by the Court, and the costs thereof shall be borne by the surviving or resulting corporation.

(g) At the hearing on such petition, the Court shall determine the stockholders who have complied with this section and who have become entitled to appraisal rights. The Court may require the stockholders who have demanded an appraisal for their shares and who hold stock represented by certificates to submit their certificates of stock to the Register in Chancery for notation thereon of the pendency of the appraisal proceedings; and if any stockholder fails to comply with such direction, the Court may dismiss the proceedings as to such stockholder.

(h) After the Court determines the stockholders entitled to an appraisal, the appraisal proceeding shall be conducted in accordance with the rules of the Court of Chancery, including any rules specifically governing appraisal proceedings. Through such proceeding the Court shall determine the fair value of the shares exclusive of any element of value arising from the accomplishment or expectation of the merger or consolidation, together with interest, if any, to be paid upon the amount determined to be the fair value. In determining such fair value, the Court shall take into account all relevant factors. Unless the Court in its discretion determines otherwise for good cause shown, interest from the effective date of the merger through the date of payment of the judgment shall be compounded quarterly and shall accrue at 5% over the Federal Reserve discount rate (including any surcharge) as established from time to time during the period between the effective date of the merger and the date of payment of the judgment. Upon application by the surviving or resulting corporation or by any stockholder entitled to participate in the appraisal proceeding, the Court may, in its discretion, proceed to trial upon the appraisal prior to the final determination of the stockholders entitled to an appraisal. Any stockholder whose name appears on the list filed by the surviving or resulting

E-3

corporation pursuant to subsection (f) of this section and who has submitted such stockholder’s certificates of stock to the Register in Chancery, if such is required, may participate fully in all proceedings until it is finally determined that such stockholder is not entitled to appraisal rights under this section.

(i) The Court shall direct the payment of the fair value of the shares, together with interest, if any, by the surviving or resulting corporation to the stockholders entitled thereto. Payment shall be so made to each such stockholder, in the case of holders of uncertificated stock forthwith, and the case of holders of shares represented by certificates upon the surrender to the corporation of the certificates representing such stock. The Court’s decree may be enforced as other decrees in the Court of Chancery may be enforced, whether such surviving or resulting corporation be a corporation of this State or of any state.

(j) The costs of the proceeding may be determined by the Court and taxed upon the parties as the Court deems equitable in the circumstances. Upon application of a stockholder, the Court may order all or a portion of the expenses incurred by any stockholder in connection with the appraisal proceeding, including, without limitation, reasonable attorney’s fees and the fees and expenses of experts, to be charged pro rata against the value of all the shares entitled to an appraisal.

(k) From and after the effective date of the merger or consolidation, no stockholder who has demanded appraisal rights as provided in subsection (d) of this section shall be entitled to vote such stock for any purpose or to receive payment of dividends or other distributions on the stock (except dividends or other distributions payable to stockholders of record at a date which is prior to the effective date of the merger or consolidation); provided, however, that if no petition for an appraisal shall be filed within the time provided in subsection (e) of this section, or if such stockholder shall deliver to the surviving or resulting corporation a written withdrawal of such stockholder’s demand for an appraisal and an acceptance of the merger or consolidation, either within 60 days after the effective date of the merger or consolidation as provided in subsection (e) of this section or thereafter with the written approval of the corporation, then the right of such stockholder to an appraisal shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery shall be dismissed as to any stockholder without the approval of the Court, and such approval may be conditioned upon such terms as the Court deems just; provided, however that this provision shall not affect the right of any stockholder who has not commenced an appraisal proceeding or joined that proceeding as a named party to withdraw such stockholder’s demand for appraisal and to accept the terms offered upon the merger or consolidation within 60 days after the effective date of the merger or consolidation, as set forth in subsection (e) of this section.

(l) The shares of the surviving or resulting corporation to which the shares of such objecting stockholders would have been converted had they assented to the merger or consolidation shall have the status of authorized and unissued shares of the surviving or resulting corporation.

INFORMATION NOT REQUIRED IN THE PROSPECTUS


Item 20.	*Indemnification of Directors and Officers*

Section 102 of the Delaware General Corporation Law allows a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Skyworks Solutions, Inc. has included such a provision in its Certificate of Incorporation.

Section 145 of the General Corporation Law of Delaware provides that a corporation has the power to indemnify a director, officer, employee or agent of the corporation and certain other persons serving at the request of the corporation in related capacities against amounts paid and expenses incurred in connection with an action or proceeding to which he is or is threatened to be made a party by reason of such position, if such person shall have acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal proceeding, if such person had no reasonable cause to believe his conduct was unlawful; provided that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the adjudicating court determines that such indemnification is proper under the circumstances.

Section 14 of Skyworks’ Second Amended and Restated By-laws provides that a director or officer:


	•	Shall be indemnified by Skyworks against all expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in any action, suit or proceeding (other than an action by or in the right of Skyworks) brought against such person by virtue of his or her position as a Skyworks director or officer if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of Skyworks, and with respect to any criminal action or proceeding, had no reasonable cause to believe his or her conduct was unlawful; and

	•	Shall be indemnified by Skyworks against all expenses (including attorneys’ fees) actually and reasonably incurred in connection with the defense or settlement of any action or suit by or in the right of Skyworks brought against such person by virtue of his or her position as a Skyworks director or officer if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of Skyworks, except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable to Skyworks unless a court shall determine that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses.

In addition, to the extent that a director or officer has been successful, on the merits or otherwise, in defense of any action, suit or proceeding such person is required to be indemnified by Skyworks against expenses (including attorneys’ fees) actually and reasonably incurred. Expenses will be advanced to a director or officer at such person’s request, provided that he or she undertakes to repay the amount received if it is ultimately determined that he or she is not entitled to indemnification for such expenses.

Skyworks has purchased directors’ and officers’ liability insurance which would indemnify its directors and officers against damages arising out of certain kinds of claims which might be made against them based on their negligent acts or omissions while acting in their capacity as such.

Item 22.	*Undertakings.*

a. The undersigned registrant hereby undertakes:

1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

i. To include any prospectus required by section 10(a)(3) of the Securities Act of 1933;

ii. To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

iii. To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

2. That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

4. That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

5. That, for the purpose of determining liability of the registrant under the Securities Act of 1933 to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

i. Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

II-3

ii. Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

iii. The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

iv. Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

b. The undersigned registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

c. The undersigned registrant hereby undertakes as follows:

1. That prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this registration statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

2. That every prospectus (i) that is filed pursuant to paragraph (c)(1) immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the registration statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To respond to requests for information that is incorporated by reference into the proxy statement/prospectus pursuant to Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

4. To supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
