PROXY STATEMENT

---

GENERAL INFORMATION

        This Proxy Statement is being furnished in connection with the solicitation of proxies by the Board of Directors of OSI Systems, Inc. (the "Company") for use at our Annual Meeting of Stockholders ("Annual Meeting"), to be held at 10:00 a.m., local time on December 6, 2016, at our offices at 12525 Chadron Avenue, Hawthorne, California 90250, and at any adjournment thereof.

        We are making our proxy materials, which include the Notice of Annual Meeting of Stockholders, Proxy Statement, Proxy Card and our most recent Annual Report on Form 10-K ("Proxy Materials"), available to our stockholders via the Internet, although registered stockholders and those stockholders who have previously requested to receive printed copies instead will receive their Proxy Materials in the mail. We anticipate that the Notice of Internet Availability of Proxy Materials will be mailed on or about October 27, 2016.

        Stockholders of record as of the close of business on October 12, 2016 will receive a Notice of Internet Availability of Proxy Materials. The Notice of Internet Availability of Proxy Materials contains instructions about how to access the Proxy Materials and vote via the Internet without attending the Annual Meeting. If you receive a Notice of Internet Availability of Proxy Materials but would instead prefer to receive a printed copy of the Proxy Materials rather than downloading them from the Internet, you may do so by following the instructions for requesting such materials included in the Notice of Internet Availability of Proxy Materials.

        If you are a stockholder that receives a printed copy of the Proxy Materials by mail, you may view the Proxy Materials on the Internet at http://www.proxyvote.com. However, in order to direct your vote without attending the Annual Meeting you must complete and mail the Proxy Card or voting instruction card enclosed (postage pre-paid return envelope also enclosed) or, if indicated on the Proxy Card that you receive, by telephone or Internet voting. Please refer to the Proxy Card that you receive for instructions.

        When a proxy is properly submitted, the shares it represents will be voted in accordance with any directions noted thereon. Any stockholder giving a proxy has the power to revoke it at any time before it is voted by written notice to the Secretary of the Company by issuance of a subsequent proxy as more fully described on the Proxy Card. In addition, a stockholder attending the Annual Meeting may revoke his or her proxy and vote in person if he or she desires to do so, but attendance at the Annual Meeting will not of itself revoke the proxy.

        At the close of business on October 12, 2016, the record date for determining stockholders entitled to notice of and to vote at the Annual Meeting, we had issued and outstanding 18,926,290 shares of common stock, $0.001 par value ("Common Stock"). A majority of the shares issued and outstanding on the record date, present in person at the Annual Meeting or represented at the Annual Meeting by proxy, will constitute a quorum for the transaction of business. Shares that are voted "FOR ALL," "FOR," "FOR ALL EXCEPT," "WITHHOLD ALL," "AGAINST" or "ABSTAIN" (as applicable) for a proposal are treated as being present at the Annual Meeting for purposes of establishing a quorum. Each share of Common Stock entitles the holder of record thereof to one vote on any matter coming before the Annual Meeting.

        A Proxy Card, when properly submitted via the Internet, telephone or mail, also confers discretionary authority with respect to amendments or variations to the matters identified in the Notice of Annual

1

Table of Contents

Meeting of Stockholders and with respect to other matters which may be properly brought before the Annual Meeting. At the time of printing this Proxy Statement, our management was not aware of any other matters to be presented for action at the Annual Meeting. If, however, other matters which are not now known to management should properly come before the Annual Meeting, the proxies hereby solicited will be exercised on such matters in accordance with the best judgment of the proxy holders.

        Abstentions and broker non-votes represented by submitted proxies will be included in the calculation of the number of the shares present at the Annual Meeting for the purposes of determining a quorum. "Broker non-votes" means shares held of record by a broker that are not voted because the broker has not received voting instructions from the beneficial owner of the shares and either lacks or declines to exercise the authority to vote the shares in its discretion.

        Proposal One.    In accordance with our Bylaws, directors are elected by a plurality of the votes cast, and the nominees who receive the most votes will be elected. Proposal One is considered a "non routine" matter and, accordingly, brokerage firms and nominees do not have the authority to vote their clients' unvoted shares on Proposal One or to vote their clients' shares if the clients have not furnished voting instructions within a specified period of time prior to the Annual Meeting. Abstentions and broker non-votes will not be counted as votes cast and will have no effect on the outcome of the vote on Proposal One. Votes marked "withhold" will not affect the outcome of the election of directors.

        Proposal Two.    In accordance with our Bylaws, to be approved, the ratification of Moss Adams LLP as our independent registered accounting firm must receive the affirmative vote of the majority of the shares of Common Stock present in person or by proxy and cast at the Annual Meeting. Proposal Two is considered a "routine" matter and, accordingly, brokerage firms and nominees have the authority to vote their clients' unvoted shares on Proposal Two as well as to vote their clients' shares if the clients have not furnished voting instructions within a specified period of time prior to the Annual Meeting. Abstentions and broker non-votes will not be counted as votes cast and will have no effect on the outcome of the vote on Proposal Two.

        Proposal Three.    To be approved, the proposal regarding the first amendment to our ESPP must receive the affirmative vote of the majority of the shares of Common Stock outstanding as of the record date. Proposal Three is considered a "non-routine" matter and, accordingly, brokerage firms and nominees do not have the authority to vote their clients' unvoted shares on Proposal Three or to vote their clients' shares if the clients have not furnished voting instructions within a specified period of time prior to the Annual Meeting. Abstentions and broker non-votes will have the same effect as a vote "against" Proposal Three.

        Proposal Four.    In accordance with our Bylaws, to be approved, the proposal regarding our executive compensation for the fiscal year ended June 30, 2016 must receive the affirmative vote of the majority of the shares of Common Stock present in person or by proxy and cast at the Annual Meeting. Proposal Four is considered a "non-routine" matter and, accordingly, brokerage firms and nominees do not have the authority to vote their clients' unvoted shares on Proposal Four or to vote their clients' shares if the clients have not furnished voting instructions within a specified period of time prior to the Annual Meeting. Abstentions and broker non-votes will not be counted as votes cast and will have no effect on the outcome of the vote on Proposal Four. The vote on Proposal Four is advisory and therefore not binding on the Company, the Compensation Committee or the Board of Directors. Although non-binding, the Board of Directors values the opinions that our stockholders express in their votes, and the votes will provide information to the Compensation Committee regarding investor sentiment about our executive compensation philosophy, policies and practices, which the Compensation Committee will be able to consider when determining executive compensation in the future.

        All stockholders entitled to vote at the Annual Meeting will receive either the Notice of Internet Availability of Proxy Materials or a printed copy of the Proxy Materials. We will pay the expenses of

soliciting proxies for the Annual Meeting, including the cost of preparing, assembling, posting on the Internet and mailing the Notice of Internet Availability of Proxy Materials and the Proxy Materials. Proxies may be solicited personally, by mail, by e-mail, over the Internet, or by telephone, by directors, officers and regular employees of the Company who will not be additionally compensated therefore.

        The matters to be considered and acted upon at the Annual Meeting are more fully discussed below.

Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to be held on December 6, 2016:    The Proxy Notice, this Proxy Statement and Annual Report on Form 10-K for the fiscal year ended June 30, 2016 are available at http://www.proxyvote.com.

ELECTION OF DIRECTORS
(Proposal No. 1 of the Proxy Card)

Nominees

        The Board of Directors consists of seven members. At each annual meeting of stockholders, directors are elected for a term of one year to succeed those directors whose terms expire on the annual meeting date.

        The seven candidates nominated for election as directors at the Annual Meeting are Deepak Chopra, Ajay Mehra, Steven C. Good, Meyer Luskin, William F. Ballhaus, James B. Hawkins and Gerald Chizever. All of our director nominees are currently directors of the Company and, with the exception of Mr. Chizever who was appointed in October 2016, were previously elected to serve on the Board of Directors by our stockholders.

        The enclosed Proxy will be voted in favor of these individuals unless other instructions are given. If elected, the nominees will serve as directors until our next annual meeting of stockholders, and until their successors are elected and qualified. If any nominee declines to serve or becomes unavailable for any reason, or if a vacancy occurs before the election (although we know of no reason to anticipate that this will occur), the proxies may be voted for such substitute nominees as the Board of Directors may designate.

        If a quorum is present and voting, the seven nominees for directors receiving the highest number of votes will be elected as directors. Abstentions and shares held by brokers that are present, but not voted because the brokers were prohibited from exercising discretionary authority (broker non-votes) will be counted as present only for purposes of determining if a quorum is present.

        The current directors and nominees for election as directors at this meeting are as follows:

Relationships Among Directors or Executive Officers

        There are no arrangements or understandings known to the Company between any of the directors or nominees for director of the Company and any other person pursuant to which any such person was or is to be elected a director.

        Ajay Mehra is the first cousin of Deepak Chopra. Other than this relationship, there are no family relationships among the directors or Named Executive Officers (as defined in "Compensation of Executive Officers and Directors – Summary Compensation Table") of the Company.

Board Role in Risk Oversight

        The Board of Directors is responsible for risk oversight of the Company. Risks facing the Company include competitive, economic, operational, financial, accounting, liquidity, tax, regulatory, foreign country, safety, employment, political, and other risks. Risks are reported to the Board of Directors through our executive officers, who are responsible for the identification, assessment and management of

6

Table of Contents

the Company's risks. The Board of Directors regularly discusses the risks reported by our executive officers and reviews with management strategies and actions to mitigate the risks and the status and effectiveness of such strategies and actions.

        To optimize its risk oversight capabilities and efficiently oversee the Company's risks, the committees of the Board of Directors are delegated oversight responsibility for particular areas of risk. For example, the Audit Committee oversees management of major financial and enterprise risks, including risks related to accounting, auditing, financial reporting, maintaining effective internal control over financial reporting, legal and compliance. The Nominating and Governance Committee oversees risks related to the effectiveness of the Board of Directors. The Compensation Committee oversees risks related to the Company's executive compensation policies and practices. The Executive Committee oversees risks related to the Company's strategic transactions. The Technology Committee oversees risks related to technology matters.

Board Leadership Structure and Lead Independent Director

        The Chairman of the Board of Directors is the Company's Chief Executive Officer. We believe that currently combining the positions of Chief Executive Officer and Chairman serves as an effective link between management's role of identifying, assessing and managing risks and the Board of Directors' role of risk oversight. Mr. Chopra possesses in-depth knowledge of the issues, opportunities and challenges the Company faces and is thus well positioned to develop agendas and highlight issues that ensure that the Board of Directors' time and attention are focused on the most critical matters. In addition, the Board of Directors has determined that this leadership structure is optimal because it believes that having one leader serving as both the Chairman and Chief Executive Officer provides decisive, consistent and effective leadership, as well as clear accountability. Having one person serve as Chairman and Chief Executive Officer also enhances our ability to communicate our message and strategy clearly and consistently to our stockholders, employees, and other companies with which we do business. Although we believe that the combination of the Chairman and Chief Executive Officer roles is appropriate under current circumstances, we will continue to review this issue periodically to determine whether, based on the relevant facts and circumstances, separation of these offices would serve our best interests and the best interests of our stockholders.

        The combined Chairman of the Board and Chief Executive Officer position is balanced by the number of independent directors serving on our Board of Directors, our independent committees and our lead independent director. Mr. Luskin is currently our lead independent director and brings to this role considerable skills and experience as described above in "Election of Directors." The role of lead independent director is designed to further promote the independence of our Board of Directors and appropriate oversight of management and to facilitate free and open discussion and communication among our independent directors.

Board of Directors Meetings, Independence and Committees of the Board of Directors

        There were eight meetings of the Board of Directors and the Board of Directors acted pursuant to unanimous written consent on one additional occasion during the fiscal year ended June 30, 2016. The Board of Directors has established an Audit Committee, Compensation Committee, Nominating and Governance Committee, Executive Committee and Technology Committee. The members of each committee are appointed by the majority vote of the Board of Directors. All persons serving as a director during the fiscal year ended June 30, 2016 attended more than 75% of the aggregate number of meetings held by the Board of Directors and all committees on which such director served.

        The Board of Directors has determined that each of the nominees for director, except Mr. Chopra and Mr. Mehra, is independent within the meaning of the director independence standards of The NASDAQ Stock Market (the "Listing Standards"), as currently in effect. Furthermore, the Board of

7

Directors has determined that each of the members of each of the committees of the Board of Directors is independent within the meaning of the rules and regulations of the U.S. Securities and Exchange Commission ("SEC") and the Listing Standards, as currently in effect.

Audit Committee

        We have a separately designated, standing Audit Committee established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). The Audit Committee makes recommendations for selection of our independent public accountants, reviews with the independent public accountants the plans and results of the audit engagement, approves professional services provided by the independent public accountants, reviews the independence of the independent public accountants, considers the range of audit and any non-audit fees, and reviews our financial statements and the adequacy of our internal accounting controls and financial management practices. All members of the Audit Committee are independent, as independence for audit committee members is defined in Rule 10A-3(b)(1) under the Exchange Act and the Listing Standards applicable to the Company.

        The Audit Committee currently consists of four independent directors – Messrs. Good, Luskin and Hawkins and Dr. Ballhaus. The Board of Directors has determined that, based upon his work experience, Mr. Good qualifies as an "Audit Committee Financial Expert" as this term has been defined under the rules and regulations of the SEC. Information regarding Mr. Good's work experience is set forth above under "Election of Directors." To date, no determination has been made as to whether the other members of the Audit Committee also qualify as Audit Committee Financial Experts.

        There were four meetings of the Audit Committee during the fiscal year ended June 30, 2016. See "Report of Audit Committee."

        The Nominating and Governance Committee will consider director candidates based upon their business and financial experience, personal characteristics, expertise that is complementary to the background and experience of other Board of Directors members, willingness to devote the required amount of time to carrying out the duties and responsibilities of membership on the Board of Directors,

willingness to objectively appraise management performance, and any such other qualifications the Nominating and Governance Committee deems necessary to ascertain the candidate's ability to serve on the Board of Directors.

        The Nominating and Governance Committee has sought to identify director nominees that have diverse professional and educational backgrounds that are believed to complement the skills offered by existing Board of Directors members.

Executive Committee

We may also require any proposed nominee to furnish such other information as we or the Nominating and Governance Committee may reasonably require to determine the eligibility of the nominee to serve as a director. In performing its evaluation and review, the Nominating and Governance Committee generally does not differentiate between candidates proposed by stockholders and other proposed nominees, except that the Nominating and Governance Committee may consider, as one of the factors in its evaluation of stockholder recommended candidates, the size and duration of the interest of the recommending stockholder or stockholder group in the equity of the Company.

RATIFICATION OF SELECTION OF
INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM
(Proposal No. 2 of the Proxy Card)

        The Audit Committee of the Board of Directors has selected Moss Adams LLP ("Moss Adams") as our independent registered public accountants for the year ending June 30, 2017 and has further directed that management submit the selection of independent registered public accountants for ratification by our stockholders at the Annual Meeting.

        The Board of Directors recommends a vote "FOR" the ratification of Moss Adams as the Company's independent registered public accountants for the fiscal year ending June 30, 2017.

APPROVAL OF FIRST AMENDMENT TO THE
AMENDED AND RESTATED OSI SYSTEMS, INC.
2008 EMPLOYEE STOCK PURCHASE PLAN
(Proposal No. 3 of the Proxy Card)

Introduction

        We are asking stockholders to approve the First Amendment (the "Amendment") to the Amended and Restated OSI Systems, Inc. 2008 Employee Stock Purchase Plan (the "ESPP") to (i) provide that the Board of Directors may amend, modify or terminate the ESPP, subject to such stockholder approval as the Board of Directors determines to be necessary or advisable to comply with applicable law or rule, and (ii) remove the ESPP's automatic termination provision which would otherwise cause the ESPP to expire on August 25, 2018. The Board of Directors approved the Amendment on October 20, 2016, subject to stockholder approval. The Amendment will become effective immediately upon stockholder approval at the Annual Meeting. If the Amendment is not approved by our stockholders, the Amendment will not become effective, the ESPP will continue in full force and effect, and shares of the Common Stock may continue to be issued under the ESPP, subject to its existing terms, conditions and limitations.

        The purpose of the ESPP is to provide employees of the Company and certain of our subsidiaries with an opportunity to purchase shares of Common Stock at a discount through accumulated payroll deductions at levels elected by the employees. The terms of the ESPP provide that no amendment to the ESPP will be effective until such amendment is approved by a vote of a majority of our stockholders if such amendment would:

•

increase the aggregate number of shares of Common Stock to be issued under the ESPP (other than due to adjustments upon changes in capitalization);



•

materially modify the eligibility requirements to participate in the ESPP;



•

increase the maximum number of shares of Common Stock which a participant may purchase in any Offering Period (as defined below);



•

extend the term of the ESPP;



•

alter the option price per share formula to reduce the price for shares of Common Stock to be purchased under the ESPP;



•

otherwise materially increase the benefits accruing to participants under the ESPP; or



•

cause the ESPP to fail to meet the "employee stock purchase plan" requirements under Section 423 of the Internal Revenue Code of 1986, as amended (the "Code").

        The terms of the ESPP further state that it will automatically terminate on the date prior to the tenth anniversary of the date on which the ESPP was adopted, or August 25, 2018. We propose that stockholders approve the Amendment to (i) provide that the Board of Directors may amend, modify or terminate the ESPP, subject to such stockholder approval as the Board of Directors determines to be necessary or advisable to comply with applicable law or rule, and (ii) remove the ESPP's automatic termination provision such that there will no longer be a fixed termination date for the ESPP. The Amendment will allow us to continue to offer to our employees the benefits of the ESPP beyond August 25, 2018, unless and until the ESPP is otherwise terminated or the shares of Common Stock reserved for issuance thereunder are exhausted.

        The Amendment is consistent with our desire to continue to afford eligible employees an opportunity to obtain a proprietary interest in the continued growth and prosperity of the Company through purchases of Common Stock, which we believe is beneficial to both the Company and our employees.

Table of Contents

        We are not asking stockholders to approve any increase to the number of shares reserved for issuance under the ESPP. When originally approved, an aggregate of 1.5 million shares were reserved for issuance under the ESPP. As of the end of the purchase period ending June 30, 2016, there were 893,119 shares remaining for issuance.

Description of the ESPP

        The following is a summary of the principal provisions of the ESPP, as amended. This summary does not purport to be a complete description of all of the provisions of the ESPP. It is qualified in its entirety by reference to the full text of the ESPP, as amended. The Amendment is included as Appendix A to this Proxy Statement.

Number of Authorized Shares

        The maximum aggregate number of shares of Common Stock that may be issued under the ESPP is 1,500,000 shares. As of the end of the purchase period ending June 30, 2016, of this 1,500,000 shares of Common Stock, a total of 893,119 shares remained available for issuance.

Administration

        The ESPP is administered by the Board of Directors or a committee appointed by the Board of Directors (the "Committee"). All determinations by the Committee are, to the full extent permitted by law, final and binding upon all parties.

Offering and Exercise Periods

        The ESPP has been implemented as a series of overlapping 24 month offering periods (each, an "Offering Period"). That is, a new Offering Period commences every six months, beginning on January 1 and July 1 of each year and consists of four exercise periods of six months each ("Exercise Periods"). The Board of Directors or the Committee may change the number and/or duration of the Exercise Periods or the length or date of commencement of an Offering Period at any time.

Eligibility

        Each employee of the Company, our U.S. subsidiaries or any other designated subsidiaries whose date of hire was at least ninety days prior to the commencement of an Offering Period and who is customarily employed by the Company for at least twenty hours per week and more than five months per calendar year are eligible to participate in the ESPP. An eligible employee may become a participant by completing an enrollment form authorizing payroll deductions and delivering it to our human resources office no later than ten days prior to the applicable enrollment date. An enrollment form will automatically enroll a participant in the ESPP for each successive Offering Period until such participant timely submits a new payroll deduction authorization, withdraws from participation under the ESPP or becomes ineligible to participate in the ESPP. As of June 30, 2016, approximately 1,363 employees were eligible to participate in the ESPP, of which eight were executive officers of the Company.

Grant of Option; Purchase Price; Limitations

        On the first day of each Offering Period (the "Offering Date"), each eligible employee participating in such Offering Period will be granted an option to purchase, on the last day of each Exercise Period in such Offering Period (the "Exercise Date"), a number of shares of Common Stock determined by dividing such employee's accumulated payroll deductions by the lower of: (i) 85% of the fair market value of one share of Common Stock on the Offering Date or (ii) 85% of the fair market value of one share of Common Stock on the applicable Exercise Date. However, if any Exercise Date of an Offering Period occurs following the 27 month anniversary of the applicable Offering Date for any reason, the per share purchase

13

---

Table of Contents

price for Common Stock for such Exercise Period will equal 85% of the fair market value of a share of Common Stock on the applicable Exercise Date.

        Unless a participating employee withdraws from the ESPP, his or her option will be automatically exercised on each Exercise Date of the Offering Period and will automatically expire upon the termination of each Offering Period; provided, however, that in no event will an employee be permitted to purchase during an Exercise Period a number of shares of Common Stock in excess of the number determined by dividing $12,500 by the fair market value of a share of Common Stock on the Offering Date.

        In addition, no employee will be granted an option under the ESPP if, immediately after grant, the employee would own stock possessing 5% or more of the voting power or value of all classes of stock of the Company or of any of our subsidiaries (including stock which may be purchased under the ESPP or pursuant to any other options), nor will any employee be permitted to participate to the extent such employee could purchase more than $25,000 worth of Common Stock (determined at the fair market value of the shares at the time the option is granted) under all employee stock purchase plans of the Company in any calendar year.

        Participants must notify us of any disposition or other transfer of any shares of Common Stock acquired under the ESPP if such disposition or transfer is made within two years after the applicable Offering Date or within one year after the applicable Exercise Date.

Payroll Deductions

        Payroll deductions commence on the first payday following the Offering Date. The purchase price for the shares is accumulated by payroll deductions during the Offering Period. The deductions may not exceed 10% of a participant's eligible compensation, which is defined in the plan to mean the participant's base rate of pay, including commissions and cash bonuses, but excluding income with respect to stock options, restricted stock awards or other stock purchases and expense reimbursements. A participant may decrease (but not increase) payroll deductions up to four times during an Offering Period. A participant may also discontinue his or her participation in the ESPP at any time during the Offering Period, in which case such participant's payroll deductions credited to his or her account will be paid to such employee. Upon termination of an Offering Period, a participant will automatically participate in the subsequent Offering Period at the same payroll deduction percentage unless the participant delivers a different authorization or the participant becomes ineligible for participation in the ESPP.

Automatic Transfer to Lower-Price Offering Period

        In the event that the fair market value of a share of Common Stock is lower on an Exercise Date than it was on such Offering Period's Offering Date, the Offering Period will automatically be terminated following such Exercise Date. A new Offering Period will begin on the day following such Exercise Date, and participants in the terminated Offering Period will be automatically enrolled at the same levels in the Offering Period beginning on the day following the terminated Offering Period. As noted above, the duration, timing and terms of Offering Periods may be changed by the Committee at any time.

Withdrawal; Termination of Employment

        Participants may withdraw from participation in the ESPP at any time, in which case such participant's payroll deductions credited to his or her account will be paid to such participant. Once a participant withdraws from the ESPP, that participant may elect to participate again for any subsequent Offering Period (so long as the participant is then eligible to participate in the ESPP and elects to participate). If a participant experiences a termination of employment, we will pay to such participant any amounts in his or her account. A participant may withdraw all, but not less than all, of the payroll deductions credited to such participant's account by giving us written notice.

Table of Contents

Transferability

        No rights or accumulated payroll deductions of a participant under the ESPP may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will or the laws of descent and distribution), and any such attempt may be treated by us as an election to withdraw from the ESPP.

Adjustments Upon Changes in Capitalization, Dissolution, Merger, Asset Sale or Change of Control

        The number of shares of Common Stock reserved under the ESPP, the number of shares of Common Stock subject to outstanding options under the ESPP which have not yet been exercised, and the price per share of Common Stock covered by each option under the ESPP which has not yet been exercised will be proportionately adjusted for any stock split, reverse stock split, stock dividend or any other increase or decrease in the number of shares of Common Stock effected without receipt of consideration by the Company. In the event of the proposed dissolution or liquidation of the Company, the Offering Period will terminate immediately prior to the consummation of such proposed action, unless otherwise provided by the Board of Directors. In the event of a proposed sale of all or substantially all the assets of the Company or a merger of the Company with or into another corporation, each option under an ongoing Offering Period will be assumed or an equivalent option will be substituted by the successor or purchaser corporation, unless the Board of Directors determines, in its sole discretion, to provide the participant with the right to exercise his or her option as to all of the option shares of Common Stock.

Amendment and Termination

        Our Board of Directors may amend, modify or terminate the ESPP at any time without notice as long as no participant's existing rights are adversely affected by such amendment, modification or termination. Stockholder approval is required under the ESPP for any amendment which would:

•

increase the aggregate number of shares of Common Stock to be issued under the ESPP;



•

materially modify the requirements for eligibility to participate in the ESPP;



•

increase the maximum number of shares of Common Stock which a participant may purchase in any Offering Period;



•

extend the term of the ESPP;



•

reduce the price for shares of Common Stock to be purchased under the ESPP;



•

otherwise materially increase the benefits accruing to participants under the ESPP; or



•

cause the ESPP to fail to meet the requirements of an "employee stock purchase plan" under Section 423 of the Code.

        If the stockholders approve the Amendment, the Board of Directors may amend, modify or terminate the ESPP, subject to such stockholder approval as the Board of Directors determines to be necessary or advisable to comply with applicable law or rule.

        Unless terminated earlier, the ESPP will automatically terminate on the date prior to the tenth anniversary of the date on which the ESPP was originally adopted, but will remain in full force until the end of the Offering Period then in effect. If the stockholders approve the Amendment, this automatic termination provision will be eliminated and will no longer apply.

Federal Tax Information

        The following information is a general summary of the federal income tax consequences of the ESPP to participants and to the Company. Tax laws may change, and actual tax consequences will depend on the participant's individual circumstances as well as state and local tax laws. We encourage all employees to

15

Table of Contents

seek tax advice when they participate in the ESPP. The ESPP is intended to qualify as an "employee stock purchase plan" under Code Section 423.

Tax Treatment of Participants

        Participants will not recognize income as a result of enrollment in the ESPP or when they purchase shares of Common Stock under the ESPP. If the participant holds the shares acquired under the ESPP until the later of one year after the Exercise Date or two years after the Offering Date, or if the participant dies while owning the shares, the participant will generally recognize ordinary income when disposing of the shares equal to the lesser of (i) the difference between the purchase price and the fair market value of the shares on the date of disposition or (ii) 15% of the fair market value of the shares on the Offering Date. Any additional gain will generally be taxed as long-term capital gain. If the shares of Common Stock are sold for less than the purchase price, then there is no ordinary income, but the participant will have a long-term capital loss equal to the difference between the purchase price and the sale price. If a participant sells or gifts the shares less than one year after the Exercise Date or less than two years after the Offering Date, the participant will generally have ordinary income equal to the difference between the purchase price and the fair market value on the Exercise Date. The difference between the sale price and the fair market value on the Exercise Date will be a capital gain or loss.

Tax Treatment of Company

        When a participant recognizes ordinary income by disposing of shares before the one-year or two-year holding period ends, the Company will generally be entitled to a tax deduction in the amount of the ordinary income.

New Plan Benefits

        Participation in the ESPP is voluntary, so awards granted under the ESPP are subject to the elections of the participants. We are not requesting that additional unissued shares be authorized for use under the ESPP. As of June 30, 2016, the ESPP had approximately 893,119 shares reserved for issuance thereunder, and in fiscal year 2016, approximately 60,375 shares were issued under the ESPP. The benefits that will be awarded or paid under the amended ESPP are not currently determinable, and will vary depending on the level of participation by each individual participant (subject to the limitations described above). As of June 30, 2016, the closing price of a share of Common Stock was $58.13.

        The table below shows, for the listed individuals and specified groups, the number of shares of Common Stock purchased under the ESPP during fiscal year 2016.

        The Board of Directors unanimously recommends that you vote "FOR" the First Amendment to the ESPP. Holders of proxies solicited by this Proxy Statement will vote the proxies received by them as directed on the Proxy or, if no direction is made, in favor of this proposal. In order to be approved, this proposal must be approved by the affirmative vote of a majority of the shares of Common Stock outstanding as of the record date.

ADVISORY VOTE ON THE COMPANY'S EXECUTIVE COMPENSATION
FOR THE FISCAL YEAR ENDED JUNE 30, 2016
(Proposal No. 4 of the Proxy Card)

Background

        The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 enables our stockholders to vote to approve, on an advisory, non-binding basis, our executive compensation for the fiscal year ended June 30, 2016 as disclosed in the Proxy Statement in accordance with the SEC's rules, including Section 14A of the Exchange Act. We currently conduct this advisory vote on an annual basis, and the next advisory vote is expected to be conducted at our 2017 Annual Meeting of Stockholders.

Summary

        Our Board of Directors is committed to excellence in governance and is aware of the significant interest in executive compensation matters by investors and the general public. We are asking our stockholders to provide advisory approval of our executive compensation as such compensation is described in the "Compensation Discussion and Analysis" section, the tabular disclosure regarding such compensation and the accompanying narrative disclosure set forth in the Proxy Statement. We recognize and value the critical role that executive leadership plays in our performance. Our executive compensation philosophy is intended to ensure that executive compensation is aligned with our short- and long-term business strategy, objectives and stockholder interests. Our executive compensation is designed to attract, motivate and retain highly qualified executives. We believe that our compensation policies and procedures are centered on pay-for-performance principles and are strongly aligned with the short- and long-term interests of our stockholders.

        We urge you to review the "Compensation Discussion and Analysis" section of the Proxy Statement and executive-related compensation tables for more information.

Emphasis on Pay-For-Performance Principles

        We believe that executive compensation should be tied to the performance of the Company on both a short-term and long-term basis. We believe that our continued success is closely tied to the performance of our executive officers and have designed our compensation practices in order to reward the executives for their contributions to our overall success.

Alignment with Stockholders' Interests

        We grant annual incentives based in part on each executive's contribution to enhancing short- and long-term profitable growth of the Company. We also grant long-term equity-based incentives as a substantial component of the compensation program to reward long-term performance and further align the interests of management with those of our stockholders. We have historically used restricted stock, restricted stock units and stock options as our equity incentive vehicles because these awards enable the executives to establish a meaningful equity stake in the Company while allowing them to participate in future value creation through appreciation of the shares. These awards tie the executives' interests to those of long-term stockholders and serve to motivate the executives to lead the Company to achieve long-term financial goals that are expected to lead to increased stockholder value. In addition to linking compensation value to stockholder value, these awards generally have vesting conditions, which creates a strong retention incentive and helps ensure the continuity of our operations. For fiscal year 2016, 100% of the long-term equity incentives granted to our Named Executive Officers consisted of restricted stock units subject to performance vesting based on growth of adjusted EBITDA per share.

Long-Term Performance

        In order to promote our philosophy of pay-for-performance and furthering our objective of aligning the interests of management with those of our stockholders, we have established performance programs for certain of our executive officers. These programs focus on the achievement of our long-term financial goals and factors that create long-term stockholder value. By establishing performance targets tied to key corporate financial metrics, we are incentivizing our officers to achieve our long-term corporate objectives and ultimately increase stockholder value.

Highlights of 2016 Exeuctive Compensation Program

        The Board of Directors believes our executive compensation program is designed appropriately and that a vote in favor of the proposal is warranted, including for these reasons: (1) 100% of Named Executive Officer equity awards for fiscal 2016 were performance-based and tied to measurable pre-established targets; (2) we conducted a robust stockholder outreach and, in response to stockholder feedback, revised our annual incentive program to be performance-based and tied to measurable targets; and (3) we are committed to having strong governance standards and continue to take steps to further this commitment.

        1.     100% Performance-Based Equity Awards:    Equity awards granted to our Named Executive Officers are 100% performance-based and tied to measurable pre-established adjusted EBITDA per share goals.

        100% of the equity grants made to our Named Executive Officers during fiscal 2016 were performance-based and tied to pre-established adjusted EBITDA per share targets which require significant annual growth. 40% of the maximum number of shares that can be earned under each Named Executive Officer's 2016 award has a three-year performance component which vests or is forfeited following the end of the three-year performance cycle, subject to the achievement of the adjusted EBITDA per share growth target for fiscal 2018. If 85% of this three-year adjusted EBITDA per share target is not attained, then these shares are forfeited. The remaining 60% of the maximum number of shares that can be earned under each executive's 2016 award may vest up to 20% per year over the three-year period if annual adjusted EBITDA per share growth targets are exceeded for fiscal years 2016, 2017 and 2018, respectively. These grants were made pursuant to our Six-Year Performance Program, which was established in 2012.

        We believe that the performance metrics underlying our long-term equity incentive program are rigorous and we have not disclosed current metrics because their disclosure would allow our competitors to determine the EBITDA and pricing related to key programs, which would be competitively harmful to us. The adjusted EBITDA per share target for the three-year performance cycle ended in fiscal 2016 was $5.38.

        For fiscal 2016, we achieved 118% of the fiscal 2016 adjusted EBITDA per share target, and as a result the 60,000 shares granted to our CEO in fiscal 2014 were vested. In addition, our CEO earned 72,000 shares, consisting of 24,000 vested shares earned pursuant to the fiscal 2016 grant, 24,000 vested shares earned pursuant to the fiscal 2015 grant and 24,000 vested shares earned pursuant to the fiscal 2014 grant.

        2.     Stockholder Outreach and Annual Cash Incentives:    We conducted a robust stockholder outreach and revised our annual cash incentive program to directly address the feedback we received from our stockholders.

        The Compensation Committee takes very seriously stockholder feedback with respect to executive compensation. We conducted a robust stockholder outreach, contacting and requesting meetings with over 75% of our top 25 stockholders, so that we could better understand stockholder sentiments and concerns about our program. In response to the specific stockholder feedback we received, the Compensation Committee revised the annual cash executive officer incentive program for fiscal 2016 to be performance-

18

Table of Contents

based and formulaicly tied to measurable thresholds, targets, and maximums. The annual incentives under this program are now calculated based on the Company's pretax adjusted return on equity (AROE). Depending on the level of AROE achieved, each participating corporate Named Executive Officer will be awarded a cash incentive calculated based upon a formula up to a maximum award. We believe that the AROE metrics underlying our annual incentive program are rigorous yet achievable with significant management effort. The Compensation Committee will have the discretion to reduce each calculated award under this program by up to 20%.

        Our stockholders also indicated that our programs should be simplified and reflect overall corporate performance. In response to this, our Compensation Committee eliminated the separate Mexico SAT Incentive Program effective July 1, 2015. Accrued amounts as of the date of termination of this program were paid out to participating executives.

        3.     Corporate Governance and Best Practices:    We are committed to having strong governance standards with respect to our compensation programs, procedures and practices.

        We have taken the following actions to enhance our corporate governance and executive compensation policies:

•

Conducted a robust stockholder outreach and revised our fiscal 2016 executive compensation to address specific stockholder feedback;



•

Prohibited all hedging and pledging of Company stock by executive officers and directors. As of the date of the Proxy Statement, no shares of Company stock are pledged by any Named Executive Officer or director.



•

Adopted a robust clawback policy that provides that if an accounting restatement is required due to material non-compliance with any accounting requirements, then we will seek to recover any excess in the incentive compensation earned by all of our executive officers, regardless of whether they were at fault or not in the circumstances leading to the restatement, over the prior three years over what they would have earned if there had not been a material restatement of the financial statements. We have also included clawback provisions in each Named Executive Officer's employment agreement.



•

Established rigorous Company stock ownership guidelines requiring each executive officer to own Company stock valued at least at five times his annual base salary. These guidelines align the executives' long-term interests with those of our stockholders. In addition, prior to attaining the 5X share ownership guideline, each executive is required to retain at least 50% of the shares acquired upon exercise of options or vesting of restricted stock or unit awards, net of amounts required to pay taxes and exercise price.

        The Board of Directors believes that the information above as well as that provided in the section entitled "Compensation of Executive Officers and Directors" contained in the Proxy Statement demonstrates that our executive compensation program was designed appropriately and is working to ensure that management's interests are aligned with the stockholders' interests and support long-term value creation. The following resolution will be submitted for a stockholder vote at the Annual Meeting:

        "RESOLVED, that the stockholders of OSI Systems, Inc. approve, on an advisory basis, the compensation of the Company's Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K of the SEC, including in the section entitled "Compensation Discussion and Analysis," the accompanying compensation tables, and the related narrative disclosure contained in the Proxy Statement."

        The Board of Directors recommends that you vote "FOR" the approval of the Company's executive compensation for the fiscal year ended June 30, 2016. Holders of proxies solicited by this Proxy Statement will vote the proxies received by them as directed on the Proxy or, if no direction is made, in favor of this proposal. In order to be approved on an advisory basis, this proposal must be approved by the affirmative vote of a majority of the votes cast at the Annual Meeting.

        We conducted targeted stockholder outreach efforts to gather input on the compensation program from some of our largest stockholders. We requested meetings with over 75% of our top 25 stockholders, and we spoke with each stockholder that expressed an interest in speaking with us. Our Chief Financial Officer, General Counsel, and/or a member of our Compensation Committee generally participated in these meetings. The primary goals in soliciting feedback from our stockholders were to (a) better understand their views on our executive compensation program, (b) identify specific concerns and issues reflected in their 2015 vote, and (c) initiate discussions about proposed changes to the program. The general feedback was that our executive compensation program should be simplified, reflect overall corporate performance, and be more formulaic.

        In response to the 2015 say on pay vote and stockholder discussions, the Compensation Committee took the following actions with respect to our executive compensation program:

        At the upcoming 2016 annual meeting, we will again hold an annual advisory vote to approve executive compensation. We will continue to engage with our stockholders throughout the year, and the Compensation Committee will consider the results from this year's and future advisory votes on executive compensation, as well as any feedback received from stockholders.

Governance Highlights

        We are committed to having strong governance practices with respect to our compensation programs, practices and procedures. We believe that these practices reinforce our emphasis on tying executive

Executive Compensation Summary

Fiscal 2016 Performance

        During fiscal 2016, we (a) achieved a significant 15-year booking and successful rollout of our turnkey screening solutions program in Albania, (b) had a strong win rate for our Security division's Real Time Tomography (RTT) checked baggage screening product in the EMEA region, (c) strengthened our leadership team, (d) announced the signing of a significant strategic acquisition in our Security division, and (e) completed two acquisitions and expanded our operating margins in our Optoelectronics and Manufacturing division. We were, however, adversely impacted by certain global economic factors, including lower oil prices, sluggishness in emerging markets, and volatility in the Middle East.

        Leverage Business Infrastructure.    Even as we launched new products, entered new markets, and invested substantial amounts in R&D, we actively leveraged our business infrastructure and maintained intelligent cost management.

        Growth in Markets and Opportunities.    In fiscal 2016, we continued to expand our addressable markets through new product introductions and targeting of markets that did not previously represent a significant source of revenues. This dynamic approach has served, and we believe it will continue to serve, to sustain growth over the long term. Some of our key achievements during fiscal 2016 include the following:

•

Expanding presence with international customers for checked baggage scanning solutions, related services and support.



•

Significant 15-year booking and successful rollout of our turnkey screening solutions program in Albania.



•

Acquiring two companies in our Optoelectronics and Manufacturing division.



•

Acquiring product lines and companies that not only leverage the Company's existing operating infrastructure but also provide immediate entry into growing market segments.

        Building a Foundation for the Future.    We continue to make significant targeted investments in R&D and acquisitions. In 2016, we entered into an agreement for a significant strategic acquisition in our

Security division as well as completed two acquisitions in our Optoelectronics and Manufacturing division. We believe that these acquisitions and investments, as well as other product development programs that are currently underway, will result in enhanced business outcomes for years to come.

Role of the Compensation Committee

        Our Board of Directors appoints members to the Compensation Committee. Each member of the Compensation Committee is independent within the meaning of the rules and regulations of the SEC and the Listing Standards, as currently in effect. The Compensation Committee is responsible for establishing and approving all compensation for our Named Executive Officers, including base salaries, annual incentives, long-term equity incentive compensation, benefits and perquisites, and other compensation. The Compensation Committee may delegate certain of its responsibilities to a subcommittee, to individuals or to others.

        Compensation for each of our Named Executive Officers (other than our Chief Executive Officer) is recommended to the Compensation Committee by our Chief Executive Officer. Compensation for our Chief Executive Officer is established by the Compensation Committee on its own.

        The Compensation Committee has designed an executive compensation program that is focused on the attainment of consistent, long-term stockholder returns through (a) aligning executives' incentives with both single-year and multi-year performance, and (b) attracting and retaining executives with capabilities to lead the Company to excel in a competitive landscape. This structure is designed to emphasize pay for performance while simultaneously mitigating risk exposure.

Executive Compensation Program Elements

        The particular elements of the compensation program for our Named Executive Officers consist of both fixed compensation and variable compensation. Consistent with our pay-for-performance philosophy, we structure our compensation program such that fixed compensation is a relatively small percentage of total compensation whereas variable compensation comprises a significant percentage of total compensation. The Compensation Committee takes risk into account when establishing the compensation program and believes that the current structure appropriately balances risk and the desire to focus executives on specific annual and long-term goals while not encouraging unnecessary or excessive risk taking.

24

---

Table of Contents

        The following is an overview of the elements of our compensation and benefits programs for fiscal 2016:

        In fiscal 2016, fixed compensation comprised approximately 16% to 35% and variable compensation comprised approximately 65% to 84% of each Named Executive Officer's total compensation. Average variable compensation for the Named Executive Officers represented 80% of total compensation.

25

---

Table of Contents

        Fixed Compensation.    Fixed compensation is intended to compensate our Named Executive Officers for their ongoing responsibilities and consists of base salary. Base salary is set to attract and retain executive talent. Base salaries for our Named Executive Officers are established at levels considered appropriate in light of the duties and scope of responsibilities of each executive officer's position and the experience the individual brings to the position. Salaries are reviewed periodically, typically on an annual basis.

        The Compensation Committee takes a conservative approach with respect to base salary increases. For example, our CEO's base salary has not been increased since 2008. In determining whether base salary levels for fiscal year 2016 were appropriate, the Compensation Committee considered the minimum base salary amount provided for in the Named Executive Officer's employment agreement, as well as a determination of each Named Executive Officer's responsibilities, past performance and expected future contributions. In fiscal 2016, the Compensation Committee determined not to adjust any base salary levels for any of the Named Executive Officers.

        Variable Compensation.    Variable compensation provides our Named Executive Officers with the opportunity for substantial rewards for achieving successful performance and contributing toward sustainable and consistent stockholder returns, and consists principally of annual incentive awards and long-term incentive compensation.

        Annual Incentive Awards.     All corporate Named Executive Officers are eligible for an annual incentive pursuant to our annual incentive program. Annual incentives under this program are designed to focus our participating Named Executive Officers on annual operating achievement and near-term success. Annual incentives are calculated based on a formula tied to AROE metrics and provide for a threshold below which no incentive will be paid and a maximum award level.

        Depending on the level of AROE achieved, corporate executives can earn from 0% to 200% of base salary as follows:

26

---

Table of Contents

        The Compensation Committee considers AROE to be an effective annual performance measure for assessing the Company's efficient use of capital and return to stockholders. The AROE targets were designed to be challenging yet achievable with significant effort and management skill and were established in order to provide the executives sufficient incentive to create long-term stockholder value while at the same time ensuring appropriate risk management. The Compensation Committee retains negative discretion to reduce any awards under the annual incentive program up to 20% of the calculated value.

        Turnkey Solutions Incentive Program.     In 2015, we established an incentive program tied to the performance of our turnkey solutions business (the "Turnkey Solutions Incentive Program"). Mr. Mehra, President of the OSI Solutions Business, is the only Named Executive Officer who participates in this program. Incentives under the Turnkey Solutions Incentive Program are conditioned on the achievement of certain metrics based on the operating income and bookings of our solutions business (excluding certain operations already existing at the time of the adoption of the program). The operating income and bookings targets are believed to be challenging, but achievable with significant management effort. For fiscal year 2016, we did not achieve the operating income threshold of $10 million generated by new business. Therefore, Mr. Mehra did not earn anything under this component of the program. Mr. Mehra vested in 23,800 RSUs for achieving a bookings target of $225 million of new business in fiscal 2016.

        Long-Term Incentive Program.     In order to further promote our philosophy of pay-for-performance and furthering our objective of aligning our executive compensation with our long-term financial goals and factors that create long-term stockholder value as well as incentivizing the desired individual performance of our Named Executive Officer, we have a long-term incentive program. For fiscal 2016, our long-term incentive program was comprised of the Six-year Performance Program described in more detail below.

        The grants to our Named Executive Officers during fiscal 2016 were performance based in their entirety. The Compensation Committee believes that this vesting structure provides an incentive for our Named Executive Officers to remain with the Company and also focus the Named Executive Officers on consistently achieving corporate performance and business objectives for the benefit of our stockholders.

        Our overall long-term incentive program is designed to retain our Named Executive Officers and to align the interests of our Named Executive Officers with the long-term interests of our stockholders, namely the achievement of sustainable, long-term stock price appreciation. All equity awards are made at fair market value on the date of grant (which is the date on which the Compensation Committee authorizes the grant). Under our equity incentive plan as in effect on the date of grant, fair market value is determined by the closing price of our Common Stock on such dates.

        With respect to performance based awards, the Compensation Committee has established a six-year program for long-term performance based incentive grants for our Named Executive Officers. The program provides for yearly grants of equity or equity-tied incentives. Each award is 100% performance based and vests based on the achievement of certain one-, two- and three-year performance targets as well as a three-year performance target tied to objective adjusted EBITDA per share metrics. Upon the termination of the Mexico SAT Incentive Program, the Compensation Committee incorporated the EBITDA from the Mexico SAT project into this program. The metrics incentivize consistent, long-term growth, and were designed to be challenging, but achievable with significant effort and management skill.

27

Table of Contents

        Each fiscal year, our Named Executive Officers are awarded an initial grant, which vests if a three-year adjusted EBITDA per share target is achieved. However, if actual three-year performance falls below target, shares in the initial grant would be forfeited as follows:

        Additional shares may be earned annually for each initial grant within the three-year performance period if annual targets are exceeded as follows:

        Our adjusted EBITDA per share for fiscal year 2016 was 118% of the fiscal 2016 adjusted EBITDA per share target of $5.38. Therefore, our executive officers earned additional shares as follows: Mr. Chopra, 72,000 shares; Mr. Edrick, 33,562 shares; Mr. Mehra, 9,468 shares; and Mr. Sze, 25,913 shares.

        In the event of a change of control, the initial grant would vest upon the change of control; to the extent actual performance has exceeded target for a full fiscal year at the time of the change of control, performance for any annual periods remaining in association with a particular grant will be assumed to exceed target by the same percentage for the purposes of awarding additional incentive shares or units in connection with the change of control.

        The Compensation Committee determines, after consultation with our Chief Executive Officer, the number of equity awards to grant to our Named Executive Officers. The grant amounts for our Chief Executive Officer are determined solely by the Compensation Committee. The Compensation

28

Table of Contents

Committee considers individual performance, including the following quantitative and qualitative factors, as well as overall corporate performance.

        For fiscal year 2016 performance share calculation purposes, our Chief Executive Officer, Chief Financial Officer, General Counsel, and President of our solutions business are measured against consolidated Company performance, and division Presidents have their performance results weighted 70% based on their respective division performance and 30% based on consolidated Company performance. The Compensation Committee retains negative discretion to reduce any awards under the long-term incentive program to a lesser award or no award to any participant.

        Benefits and Perquisites.    Benefits and perquisites are designed to attract and retain key employees. Currently, our Named Executive Officers are eligible to participate in benefit plans available to all employees, including our 401(k) Plan, Employee Stock Purchase Plan, medical, dental, and vision health insurance plans and life and long-term disability insurance plans. The 401(k) Plan, Employee Stock Purchase Plan and the medical, dental and vision plans require each participant to pay a contributory amount. We have elected to pay amounts contributed to medical, dental and vision health insurance plans and life and long-term disability insurance plans on behalf of our Named Executive Officers. In addition, we maintain an executive medical reimbursement plan under which our Named Executive Officers receive reimbursement for out-of-pocket expenses not covered by their health insurance plans. Employee individual plan contributions are subject to the maximum contribution allowed by the Internal Revenue Code. We also lease automobiles for or provide an auto allowance to each of our Named Executive Officers.

        We maintain a Nonqualified Deferred Compensation Plan (the "Deferred Compensation Plan") that is unfunded for federal tax purposes and allows our Named Executive Officers and a select group of other managers or highly compensated employees (as designated by the Compensation Committee) to defer a specified percentage of certain compensation, including salary, bonuses and commissions. Distributions may be made in a lump sum (or in installments if elected in accordance with the terms of the Deferred Compensation Plan) upon termination of employment, disability, a specified withdrawal date or death. Additional information about this plan is summarized below under the heading "Nonqualified Deferred Compensation."

        We also maintain a Nonqualified Defined Benefit Plan (the "Defined Benefit Plan") that is unfunded for federal tax purposes and that constitutes an unsecured promise by the Company to make payments to participants in the future following their retirement, termination in connection with a change in control of the Company, or their death or disability. Under the terms of the Defined Benefit Plan, a committee designated by the Board of Directors may select participants from among our Named Executive Officers and a select group of managers or other highly compensated employees. Currently, Mr. Chopra is the only

29

Table of Contents

participant in this plan. Additional information about this plan is summarized below under the heading "Pension Benefits."

        Total Compensation Mix.    While the Compensation Committee does not apply a predetermined or mathematical weighting to determine the fixed and variable elements of compensation, the Compensation Committee believes that the elements described above provide a well-proportioned mix of equity based, at risk or performance based compensation, and retention based compensation that produces short-term and long-term incentives and rewards. We believe this compensation mix provides our Named Executive Officers a measure of security as to the minimum levels of compensation that they are eligible to receive, while motivating the Named Executive Officers to focus on the business measures that will produce a high level of corporate performance, as well as reducing the risk of recruitment of highly qualified executive talent by our competitors. The mix of annual incentives and the equity based awards likewise provides an appropriate balance between short-term financial performance and long-term financial and stock performance. We believe that this compensation mix results in a pay-for-performance orientation that is aligned with our compensation philosophy, which takes into account individual, group and Company performance.

Bases for Our Compensation Policies and Decisions

        In determining compensation awarded to our Named Executive Officers for fiscal 2016, the Compensation Committee performed a review of both overall and relative individual Named Executive Officer and corporate performance based on the qualitative and quantitative factors described in the table below. The factors considered did not have any predetermined or mathematical weighting; rather, the Compensation Committee considered the overall performance of each executive, considering the factors, and including consideration of unplanned events and issues emerging during the fiscal year. Each factor was evaluated and taken into consideration in the Compensation Committee's overall determination of each Named Executive Officer's total compensation package, including both the amount of compensation as well as allocation of such compensation between short-term and long-term components.

        The Compensation Committee's review included evaluating the compensation of the Named Executive Officers in light of information regarding the compensation practices and corporate financial performance of other companies. In making its determinations, the Compensation Committee reviewed information summarizing the compensation paid at peer group companies and more broad-based

30

---

Table of Contents

compensation surveys. The companies in the fiscal 2016 peer group were developed based on similarity in size and operations within the industries in which we operate as follows:

        In connection with executive compensation decisions for fiscal 2016, the Compensation Committee engaged independent compensation consultant firm, Pearl Meyer. The Compensation Committee also considered broad-based surveys that reflected compensation levels and practices for executives holding comparable positions at the companies covered by the surveys and adjustments based on the cost of living in certain geographic areas. The review of the surveys further assisted the Compensation Committee in determining the appropriate level and mix of compensation for each Named Executive Officer. In connection with its review, the Compensation Committee also considered that certain Named Executive Officers were located in the high cost of living area in the geographic location of our Company headquarters.

        While the Compensation Committee did not engage in formal benchmarking with pre-established targets, the Compensation Committee reviewed our actual performance taken as a whole as well as our performance relative to our peer group and established compensation levels at the competitive level that it believed most appropriately corresponded to our comparative performance.

        For fiscal 2016, the Compensation Committee determined that it was appropriate to maintain salary levels constant for all Named Executive Officers. The Compensation Committee believes that the fixed component of compensation is designed to compensate each Named Executive Officer based on the duties and scope of responsibilities of his position and the experience he brings to the position, which did not change materially in fiscal 2016. Consistent with the Company's pay-for-performance philosophy, the variable component of compensation, in the form of annual incentives and performance-based equity grants comprised a significant portion of total compensation.

        The Compensation Committee's compensation decisions are designed to encourage performance that enhances long-term stockholder value. The Compensation Committee believes that attracting and retaining executive talent capable of achieving our long-term, strategic objectives is the best way to align executive compensation decisions with the interests of stockholders. The Compensation Committee also believes that meeting financial targets as well as near-term strategic goals demonstrates whether an executive is on track to accomplish longer-term objectives.

Minimum Equity Ownership and Retention Guidelines

        We believe that our executive officers should hold a significant amount of Company equity to link their long-term economic interests directly to those of our stockholders. Accordingly, we have established requirements that executive officers own at minimum equity of the Company valued at five times their respective annual base salaries. We believe that this multiple constitutes significant amounts for our executive officers and provides a substantial link between the interests of our executive officers and those of our stockholders. During such time that an executive officer has not attained the share ownership guideline, he is required to retain at least 50% of the shares acquired upon exercise of options or vesting of restricted stock awards or units, net of amounts required to pay taxes and exercise price. We periodically review our minimum equity ownership guidelines. As of June 30, 2016, each of our Named Executive Officers met or exceeded our minimum equity ownership guidelines, with the exception of Pak Chin who was appointed as an executive officer in May 2015.

Clawback Policy

        We have adopted a clawback policy. The policy provides that if an accounting restatement is required due to our material non-compliance with any accounting requirements, then we will seek to recover any excess in the incentive compensation earned by all of our executive officers, regardless of whether they were at fault or not in the circumstances leading to the restatement, over the prior three years over what they would have earned if there had not been a material non-compliance in the financial statements. Each Named Executive Officer's employment agreement also contains a clawback provision.

Policy Prohibiting the Hedging or Pledging of Company Stock

        We have adopted a policy that prohibits our executive officers and directors from entering into any transaction that is designed to hedge or offset any decrease in the market value of our Common Stock or other equity securities. We have also adopted a policy that prohibits our executive officers and directors from holding Company stock or other equity securities in margin accounts or pledging Company stock or other equity securities as collateral for a loan. As of the date of this Proxy Statement, no shares of Company stock are pledged by any Named Executive Officer or director.

Employment Agreements

        We have entered into employment agreements with Messrs. Chopra, Edrick, Mehra, and Sze and an offer letter with Mr. Chin. The terms of each of such agreements or arrangements are summarized below under the heading "Employment Agreements." These types of arrangements are used to retain executives and formalize the terms of the executives' employment.

Impact of Accounting and Tax on the Form of Compensation

        The Compensation Committee considers applicable tax laws, securities laws and accounting regulations in structuring and modifying its compensation arrangements and employee benefit plans. The Compensation Committee has considered the impact of generally accepted accounting principles on our use of equity based awards. The Compensation Committee also considers the limits on deductibility of compensation imposed by Section 162(m) of the Internal Revenue Code with respect to annual compensation exceeding $1.0 million and Section 280G of the Internal Revenue Code with respect to change in control payments exceeding specified limits.

Pension Benefits

        We maintain the Defined Benefit Plan. The Defined Benefit Plan constitutes an unsecured promise by the Company to make payments to participants upon vesting. Mr. Chopra is currently the only participant in the Defined Benefit Plan.

        Under the terms of his participation, Mr. Chopra will be entitled to a total benefit of $10 million payable over a 10-year period commencing January 1, 2019 in quarterly installments of $250,000. Mr. Chopra is fully vested in all benefits under the Defined Benefit Plan. In the event of Mr. Chopra's death or disability, he or his dependents shall be entitled to $10 million payable over 10 years commencing within 60 days following his death or disability, as applicable. In the event of Mr. Chopra's Separation from Service (as defined in the Defined Benefit Plan) within 24 months following a Change in Control (as defined in the Defined Benefit Plan), Mr. Chopra shall be entitled to (i) the net present value of $6 million of his retirement benefit payable in a single lump sum within 90 days following his Separation from Service and (ii) the net present value of $4 million of his retirement benefit payable in the form of a single lump sum 90 days following the first anniversary of his Separation from Service, each subject to Section 409A of the Internal Revenue Code. In the event a Change in Control occurs after his Separation from Service

during the payout of Mr. Chopra's benefits, the present value of all remaining payments shall be paid in the form of a single lump sum within 90 days following the Change in Control.

        The following table sets forth information regarding the Defined Benefit Plan for the participating Named Executive Officer during fiscal year ended June 30, 2016(1). For a discussion of the valuation method and all material assumptions applied in quantifying the present value of the current accrued benefit, please see Note 12 to the Consolidated Financial Statements included in our Form 10-K for the year ended June 30, 2016.

Nonqualified Deferred Compensation

        We adopted the Deferred Compensation Plan in May 2008, as amended and restated in April 2014. Under the Deferred Compensation Plan, a select group of our management or highly compensated employees (as designated by the Compensation Committee), including our Named Executive Officers, may defer a specified percentage of their salary, bonuses and commissions and thereby defer taxation of these deferred amounts until actual payment of the deferred amounts in future years. The Named Executive Officers may elect to defer up to 80% of their base salary and up to 100% of other types of eligible compensation. The Deferred Compensation Plan also allows us to make discretionary contributions and matching contributions on behalf of eligible participants.

        Participating Named Executive Officers receive market-based returns on their deferred compensation amounts based on the performance of a variety of mutual fund-type investment vehicles chosen by them and which are similar to the investment vehicles made available to all employees participating in the Deferred Compensation Plan. Participants may at any time change their investment allocations among the investment vehicles made available under the Deferred Compensation Plan. The rates of return for the various investment vehicles for deferred amounts in the Deferred Compensation Plan in fiscal 2016 ranged from –9.96% to 5.25%.

        Distributions to participants may be made in a lump sum (or in installments if elected in accordance with the terms of the Deferred Compensation Plan) upon termination of employment, disability, a specified withdrawal date or death.

Employment Agreements

        We have entered into employment agreements with Messrs. Chopra, Edrick, Mehra, and Sze and an offer letter with Mr. Chin.

Deepak Chopra's Employment Agreement

        In April 2012, we entered into our current employment agreement with Mr. Chopra, which was effective as of January 1, 2012. Mr. Chopra's employment agreement was amended, effective as of July 1, 2015. Unless the agreement is terminated earlier in accordance with its terms, the agreement has a three-year term that automatically renews on each anniversary of the effective date of the agreement for a new three year term. The employment agreement terminates on January 1 following the year in which Mr. Chopra turns 68 (the "Chopra Scheduled Retirement Date"). The agreement provides for an initial annual base salary of $1,000,000. Mr. Chopra is also eligible to receive bonus payments from the bonus pool established by us for our officers and employees and to participate in incentive compensation and other employee benefit plans established by us. Mr. Chopra is also entitled to receive the benefit award specified for him under the Defined Benefit Plan. The agreement contains certain restrictive covenants and other prohibitions that protect our proprietary and confidential information following termination and preclude Mr. Chopra during the term of the agreement and for 18 months thereafter from soliciting for hire any individual that was an executive, supervisor or manager of the Company on, or within 90 days prior to, Mr. Chopra's last date of employment with us. The agreement also contains a clawback provision whereby Mr. Chopra's incentive or performance based compensation shall be subject to reduction or

39

Table of Contents

repayment by reason of a correction or restatement of our financial information if and to the extent such reduction or repayment is required by any applicable law.

        Under the terms of the agreement, we may terminate Mr. Chopra's employment at any time for "cause" (as defined in the agreement), or for the following additional reasons: (i) in the event of Mr. Chopra's death; (ii) because of physical or mental incapacity or disability, failure to perform the essential functions of his position for an aggregate period of 180 days within any 12 month period; or (iii) without cause on 12 months written notice, each as further detailed in the agreement. Mr. Chopra may also terminate his employment agreement at any time upon 12 months written notice to the Company or upon three months notice if such termination is for "good reason" (as defined in the agreement).

        In the event of the termination of Mr. Chopra's employment by us without cause, our non-renewal of Mr. Chopra's employment agreement, or termination of such employment by Mr. Chopra for good reason, Mr. Chopra shall be entitled to a single lump-sum payment equal to three times the average of Mr. Chopra's highest two years out of the prior five years of total annual compensation, including: (i) base salary; (ii) bonuses and incentive compensation excluding "special bonus programs" (as defined in the agreement); (iii) the fair value of any stock, options or other equity grants whether vested or not and (iv) the annualized value of all benefits and perquisites. Mr. Chopra would also receive the acceleration of vesting of all stock options, equity grants and other incentive compensation awards (excluding any cash bonus attributable to performance in fiscal years that are not complete as of Mr. Chopra's last date of employment and any special bonus programs) from us to Mr. Chopra and an extension of time to exercise such stock options such that Mr. Chopra's right to exercise such stock options shall continue until the first anniversary of the last day of his employment, but in no event later than the expiration date of the options.

        In the event of the termination of Mr. Chopra's employment by us without cause or by Mr. Chopra for good reason, within 90 days prior to or 12 months after a "change in control" (as defined in the agreement), then Mr. Chopra shall be entitled to the same lump sum payment described in the previous paragraph, which shall be subject to mitigation as provided in applicable Treasury Regulations. Mr. Chopra may, at his option, and in lieu of receiving the forgoing, elect to receive a lump sum payment in an amount equal to the product of 2.99 multiplied by Mr. Chopra's "base amount" (as defined in Internal Revenue Code Section 280G(b)(3)); provided that the amount of this alternative payment shall be reduced by the value of acceleration of any equity, stock options, incentive compensation or deferred compensation accelerated by reason of termination to the extent required to be included in the "base amount" pursuant to Internal Revenue Code Section 280G.

        In the event of Mr. Chopra's continued employment until the Chopra Scheduled Retirement Date (including if Mr. Chopra becomes disabled or continues performing services for the Company in a different capacity prior to the Scheduled Retirement Date and such disability or other form of services continues through the Scheduled Retirement Date), he shall be entitled to the greater of (i) $12,500,000 or (ii) a lump sum stay bonus equal to two times the average of his highest two years out of the prior five years of total annual compensation, including (a) base salary, (b) bonuses and incentive compensation (excluding any special bonus programs), (c) the fair value of any stock, options or other equity grants whether vested or not, and (d) the annualized value of all benefits and perquisites, payable in a single lump sum cash payment within 45 days of the Chopra Scheduled Retirement Date.

Alan Edrick's and Victor Sze's Employment Agreements

        For purposes of this section, Messrs. Edrick and Sze are each individually referred to as the "Executive." In April 2012, we entered into its current employment agreement with each Executive, which were effective as of January 1, 2012. Each Executive's employment agreement was amended, effective as of July 1, 2015. The terms of such agreements are substantially identical. Unless the agreement is terminated earlier in accordance with its terms, the agreement has a one year term that shall automatically be extended for successive one year periods, unless either party delivers notice of non-renewal to the other

party at least 30 days prior to the end of the initial term or any renewal period then in effect. The employment agreement terminates on January 1 following the year in which the Executive turns 68. The agreements provide for an initial annual base salary of $402,000 for Mr. Edrick and $350,000 for Mr. Sze. The Executive is also eligible to receive bonus payments from the bonus pool established by us for our officers and employees and to participate in incentive compensation and other employee benefit plans established by us. The agreement contains certain restrictive covenants and other prohibitions that protect our proprietary and confidential information following termination and preclude the Executive during the term of the agreement and for 18 months thereafter from soliciting for hire any individual that was an executive, supervisor or manager of the Company on, or within 90 days prior to, the Executive's last date of employment with us. Each Executive's agreement also contains a clawback provision whereby the Executive's incentive or performance based compensation shall be subject to reduction or repayment by reason of a correction or restatement of our financial information if and to the extent such reduction or repayment is required by any applicable law.

        Under the terms of the agreement, we may terminate the Executive's employment at any time for "cause" (as defined in the agreement), or for the following additional reasons: (i) in the event of the Executive's death; (ii) because of physical or mental incapacity or disability, failure to perform the essential functions of his position for an aggregate period of 180 days within any 12 month period; or (iii) without cause on 30 days written notice, each as further detailed in the agreement. The Executive may also terminate his employment agreement for "good reason" (as defined in the agreement) or at any time on 30 days written notice.

        In the event of the termination of the Executive's employment by us without cause, our non-renewal of the Executive's employment agreement or the termination of such employment by the Executive for good reason, the Executive shall be entitled to: (i) an amount equal to 24 months salary at the Executive's then-current base salary plus an amount equal to two times the average of the highest three annual bonuses (excluding any special bonus programs) paid by us to the Executive in the five years preceding such termination; (ii) continuation of the Executive's car usage or allowance payments for a period of six months after separation from service; (iii) an allowance of $6,000 for outplacement services; and (iv) acceleration of vesting of all stock options, equity grants and other incentive compensation awards (excluding any cash bonus attributable to performance in fiscal years that are not complete as of the Executive's last date of employment and any special bonus programs) from us to Executive as follows: (a) grants vesting over time shall be fully vested on separation from service, (b) grants vesting based on performance shall be accelerated and fully vested on separation from service without regard to whether the performance targets are met for such performance period, and (c) the time to exercise nonqualified stock options shall be extended such that Executive's right to exercise such stock options shall continue until the first anniversary of the Executive's last date of employment, but in no event later than the expiration date of the options.

        In the event of the termination of the Executive's employment by us without cause or by the Executive for good reason, within 90 days prior to or 12 months after a "change in control" (as defined in the agreement), then the Executive shall be entitled to (i) the severance payment described in the applicable paragraph above and (ii) equity, stock options and other incentive compensation awards (excluding any cash bonus attributable to performance in fiscal years that are not complete as of the Executive's last date of employment and any special bonus programs) granted by us to Executive, whether time vested or performance vested, shall, to the extent unvested, immediately vest, and such stock options shall remain exercisable by Executive for no less than 12 months after the date of such separation from service. Under such circumstances, the Executive may, at his option, and in lieu of receiving the forgoing amounts, elect to receive a lump sum payment in an amount equal to the product of 2.99 multiplied by the Executive's "base amount" (as defined in Internal Revenue Code Section 280G(b)(3) excluding payments under any special bonus programs); provided that the amount of this alternative payment shall be reduced by the value of acceleration of any equity, stock options, incentive compensation or deferred compensation accelerated by

Unless the agreement is terminated earlier in accordance with its terms, the agreement has a one year term that shall automatically be extended for successive one year periods, unless either party delivers notice of non-renewal to the other party at least 30 days prior to the end of the initial term or any renewal period then in effect. The employment agreement terminates on January 1 following the year in which Mr. Mehra turns 68.

Potential Payment upon Termination of Employment or Change in Control

        The following tables reflect the breakdown of potential payments and benefits upon termination or a change in control required under the Named Executive Officers' current employment agreements. The tables therefore assume that the terms of the employment agreement to which each Named Executive Officer is currently subject had been in effect on June 30, 2016, and that employment terminated on such date. The tables also assume that the price of our Common Stock, on which certain calculations in the following tables are made, was the closing price of our Common Stock on June 30, 2016, the last business day of the fiscal year ($58.13).

        Please also note that regardless of the manner in which a Named Executive Officer's employment terminates, the officer is entitled to receive amounts earned during the term of employment. These amounts, which are not included in the following tables, include: (i) regular salary accrued as of the final date of employment; (ii) bonuses accrued as of the final date of employment; (iii) vacation and paid time off accrued as of the final date of employment; (iv) business expense reimbursements not yet paid as of the final date of employment; and (v) amounts contributed under our qualified and nonqualified deferred compensation plans.

        All disclosed amounts in the following tables are estimates only and do not necessarily reflect the actual amounts that would be paid to the Named Executive Officers, which amounts would only be known at the time that they become eligible for such payments.

        Subject to the foregoing, the following table reflects the breakdown of potential payments and benefits upon termination or a change in control required under Mr. Chopra's current employment agreement.

        Also subject to the foregoing, the following table reflects the breakdown of potential payments and benefits upon termination or a change in control required under the respective current employment agreements of Messrs. Edrick, Mehra, Sze and Chin.

Director Compensation

        Messrs. Chopra and Mehra receive no compensation for their service as directors of the Company. Mr. Chizever did not serve on the Board of Directors in fiscal year 2016 and therefore received no compensation from the Company in fiscal 2016.

        During the fiscal year ended June 30, 2016, each non-employee director that served as a director for the full fiscal year received $65,000 for his year of service, 2,200 RSUs, and $3,000 for each Board of Directors meeting attended (not including telephonic meetings).

        Each member of the Audit Committee received $3,000 for each Audit Committee meeting attended. In addition, the Chairman of the Audit Committee also received $15,000.

        Each member of the Compensation Committee received $3,000 for each Compensation Committee meeting attended. In addition, the Chairman of the Compensation Committee also received $15,000.

        Each member of the Nominating and Governance Committee received $3,000 for each Nominating and Governance Committee meeting attended. In addition, the Chairman of the Nominating and Governance Committee also received $7,500 and 500 RSUs.

        Each member of the Executive Committee received $25,000 and 2,600 RSUs.

        Each member of the Technology Committee received $3,000 for each Technology Committee meeting attended. In addition, the Chairman of the Technology Committee also received $7,500 and 500 RSUs.

        All RSU awards granted to members of the Board of Directors and its committees vest over a period of four years from the date of grant. The directors also are reimbursed for expenses incurred in connection with the performance of their services as directors.

        The following table provides compensation information for the fiscal year ended June 30, 2016 for each non-employee member of our Board of Directors(1):

Director Share Ownership Requirements

        We believe that our directors should hold a significant amount of Company equity to link their long-term economic interests directly to those of our stockholders. Accordingly, we have established requirements that our directors own at minimum equity of the Company valued at five times their annual retainers. We believe that this multiple constitutes significant amounts for our directors and provides a substantial link between the interests of our directors and those of our stockholders. During such time that a director has not attained the share ownership guideline, he is required to retain at least 50% of the shares acquired upon exercise of options or vesting of restricted stock or unit awards, net of amounts required to pay taxes and exercise price. We periodically review our minimum equity ownership guidelines. As of June 30, 2016, each of our directors met or exceeded our minimum equity ownership guidelines, with the exception of Mr. Hawkins who was elected as a director in December 2015.

Certain Relationships and Related Transactions

        In 1994, we, together with Electronics Corporation of India Limited ("ECIL"), an unaffiliated Indian company, formed ECIL-Rapiscan Security Products Limited, a joint venture under the laws of India ("ECIL Rapiscan"). We own a 36% interest in the joint venture, Mr. Chopra owns a 10.5% interest and Mr. Mehra owns a 4.5% interest. The remaining interest in the joint venture is owned by ECIL. We sell security and inspection kits to ECIL at a price no less favorable to us than the price we charge unaffiliated third parties for such products. To date, our portion of the earnings of ECIL Rapiscan has been immaterial to our financial results and results of operations.

        Mohinder Chopra, who is the brother of Deepak Chopra, our Chief Executive Officer, is our Senior Vice President/General Manager India. His total compensation for fiscal year 2016, which is comprised of base salary and bonus, was valued at approximately $260,000.

        Gerald Chizever, a member of our Board of Directors, is a partner at Loeb & Loeb LLP. Loeb & Loeb advises the Company in various matters from time to time. The fees paid by the Company to Loeb & Loeb in each of the past three fiscal years were significantly below the applicable threshold outlined in The NASDAQ Stock Market guidelines for determining director independence. Our Board of Directors carefully reviewed the nature of our engagement of Loeb & Loeb and the services rendered, including the expertise and relevant experience of the firm, the firm's and specific partners' knowledge of our Company and our business and past legal engagements, and the fees paid in such engagements, and determined that Mr. Chizever is independent under the standards of The NASDAQ Stock Market.

        The Audit Committee of the Board of Directors reviews proposed transactions in which the Company and any person who is a member of the Board of Directors, a nominee to become a member of the Board of Directors, an executive officer of the Company, a holder of more than five percent of our voting securities, or any immediate family member of any of the foregoing would have a direct or indirect material interest in the transaction and the amount involved, when added together with the amounts of all other transactions with that related person for that fiscal year, exceeds $75,000. The review involves an evaluation, without participation by any member of the Audit Committee with a direct or indirect material interest in the transaction, of whether the transaction would be on terms at least as favorable to us as those that could have been obtained from unaffiliated third parties. This policy is supported by the Charter of the Audit Committee of the Board of Directors.

Compensation Committee Report

        The Compensation Committee has reviewed and discussed with management the Compensation Discussion and Analysis provisions to be included in this Proxy Statement. Based on the reviews and discussions referred to above, the Compensation Committee recommends to the Board of Directors that the Compensation Discussion and Analysis referred to above be included in this Proxy Statement.

Section 16(a) Beneficial Ownership Reporting Compliance

        Section 16(a) of the Exchange Act requires the executive officers and directors and persons who beneficially own more than 10% of a class of securities registered under Section 12(b) the Exchange Act to file initial reports of ownership and reports of changes in ownership with the SEC. Such officers, directors and stockholders are required by SEC regulations to furnish us with copies of all such reports that they file. None of our directors or executive officers owns more than 10% of the our securities. Based solely upon our review of such forms furnished to us during the fiscal year ended June 30, 2016, and written representations from certain reporting persons, we believe that our executive officers and directors have complied with the requirements imposed on them by Section 16(a) of the Exchange Act.

Audit Fees

        The following table represents fees charged for professional audit services rendered by Moss Adams for the audit of our annual financial statements for the years ended June 30, 2015 and 2016 and fees billed by Moss Adams for other services during those years (in thousands):

        "Audit Fees" consist of fees billed for professional services rendered for the integrated audit of our consolidated financial statements and the review of our interim consolidated financial statements included in quarterly reports and services that are normally provided by Moss Adams in connection with statutory and regulatory filings or engagements.

        The term "Audit-Related Fees" means fees for assurance and related services that are reasonably related to the performance of the audit or review of our financial statements other than audit fees. The term "Tax Fees" means fees for professional services rendered for tax advice, planning and compliance (domestic and international). The term "All Other Fees" means fees for products and services other than for the services described above.

Audit Committee's Pre-Approval Policy

        The Audit Committee pre-approves all audit, audit-related and tax services (other than prohibited non-audit services) to be provided by the independent public accountants. The Audit Committee has delegated to its Chairman the authority to pre-approve all other services to be provided by the independent public accountants, up to an aggregate of $50,000 each fiscal year. The Chairman reports each such pre-approval decision to the full Audit Committee at its next scheduled meeting.

Independence

        The Audit Committee has considered whether Moss Adams' provision of services other than its audit of the Company's annual financial statement and its review of the Company's quarterly financial statements is compatible with maintaining such independent public accountant's independence and has determined that it is compatible.

REPORT OF AUDIT COMMITTEE

        During the fiscal year ended June 30, 2016, the Audit Committee was composed of three non-employee directors, namely, Steven C. Good, Meyer Luskin and William F. Ballhaus. Mr. Hawkins was appointed to the Audit Committee in September 2016. All members of the Audit Committee meet the independence and experience requirements of the SEC and Listing Standards. The Board of Directors has determined that Mr. Good qualifies as an "Audit Committee Financial Expert" as this term has been defined under the rules and regulations of the SEC. To date, no determination has been made as to whether the other members of the Audit Committee qualify as Audit Committee Financial Experts. The Audit Committee met four times during the fiscal year ended June 30, 2016.

        At each of its meetings, the Audit Committee met with the senior members of the Company's financial management team and the independent public accountants. The Audit Committee's agenda is established by the Audit Committee's Chairman and the Company's Chief Financial Officer. During the year, the Audit Committee had private sessions with the Company's independent public accountants at which open discussions of financial management, accounting and internal control issues took place.

        The Audit Committee recommended to the Board of Directors the engagement of Moss Adams as the Company's independent public accountants. The Audit Committee reviewed with the Company's financial managers and the independent public accountants overall audit scopes and plans, the results of internal and external audit examinations, evaluations by the auditors of the Company's internal control, and the quality of the Company's financial reporting.

        The Audit Committee has reviewed with management the audited financial statements in the Annual Report, including a discussion of the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of disclosures in the financial statements. In addressing the quality of management's accounting judgments, members of the Audit Committee asked for management's representations that the audited consolidated financial statements of the Company have been prepared in conformity with generally accepted accounting principles and have expressed to both management and the independent public accountants their general preference for conservative policies when a range of accounting options is available.

        The Audit Committee believes that by thus focusing its discussions with the independent public accountants, it can promote a meaningful dialogue that provides a basis for its oversight judgments.

        The Audit Committee also discussed with the independent public accountants all other matters required to be discussed by the independent public accountants with the Audit Committee under Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1, AU section 380), as adopted by the Public Company Accounting Oversight Board ("PCAOB") in Rule 3200T. The Audit Committee received and discussed with the independent public accountants their annual written report on their independence from the Company and its management, which is made under PCAOB Ethics and Independence Rule 3526 (Communicating with Audit Committee Concerning Independence), and considered with the independent public accountants whether the provision of services provided by them to the Company during the fiscal year ended June 30, 2016 was compatible with the independent public accountants' independence.

        Finally, the Audit Committee reviewed and discussed with management and the independent public accountants the evaluation of the Company's internal control and the audit of management's report on the effectiveness of the Company's internal control over financial reporting, as required by Section 404 of the Sarbanes Oxley Act of 2002.

        In performing all of these functions, the Audit Committee acts only in an oversight capacity. The Audit Committee reviews the Company's SEC reports prior to filing and all quarterly earnings announcements in advance of their issuance with management and representatives of the independent public accountants. In its oversight role, the Audit Committee relies on the work and assurances of the

Company's management, which has the primary responsibility for financial statements and reports, including evaluating the effectiveness of disclosure controls and procedures, and evaluating the effectiveness of internal control over financial reporting, and of the independent public accountants, who, in their report, express an opinion on the conformity of the Company's annual financial statements with accounting principles generally accepted in the United States of America, as well as expressing an opinion on (i) management's assessment of the effectiveness of internal control over financial reporting and (ii) the effectiveness of internal control over financial reporting.

        In reliance on these reviews and discussions, and the report of the independent public accountants, the Audit Committee recommended to the Board of Directors, and the Board of Directors approved, that the audited financial statements be included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2016, for filing with the SEC.
