Proxy Statement

For The
April 26, 2011
Annual Shareholders' Meeting

Dear Shareholder:

        You are cordially invited to attend Valmont's annual meeting of shareholders on Tuesday, April 26, 2011 at 2:00 p.m. The meeting will be held in the Nebraska Conference Room of the Omaha Marriott at 10220 Regency Circle in Omaha, Nebraska.

        The formal meeting of shareholders will be followed by a review of Valmont's business operations and our outlook for the future. Following the meeting, you are invited to an informal reception where you can visit with the directors and officers about the activities of the Company.

        For the first time in Valmont's history, we are pleased to furnish our proxy materials to you over the Internet. We believe that this e-proxy process should expedite shareholders' receipt of proxy materials, while also lowering the costs and reducing the environmental impact of our annual meeting. On March 17, 2011, we mailed to many of our shareholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access our proxy statement and annual report and vote online. Those shareholders who do not receive such a Notice, including shareholders who have previously requested to receive paper copies of proxy materials, will receive a copy of the proxy statement, proxy card, and annual report by mail. The proxy statement contains instructions on how you can (i) receive a paper copy of the proxy statement, proxy card, and annual report, if you only received a Notice by mail, or (ii) elect to receive your proxy statement, proxy card, and annual report over the Internet next year, if you received them by mail this year.

        Whether or not you plan to attend the meeting, your vote is important and we encourage you to vote promptly. You may vote your shares via a toll-free telephone number or over the Internet. If you received a paper copy of the proxy card by mail, you may vote by signing, dating and mailing the proxy card in the envelope provided. Instructions regarding these three methods of voting are contained on the Notice or proxy card. If you hold your shares through an account with a brokerage firm, bank, or other nominee, please follow the instructions you receive from them to vote your shares.

        I look forward to seeing you at our annual meeting.

PROXY STATEMENT

To Our Shareholders:

        The board of directors of Valmont Industries, Inc. solicits your proxy in the form enclosed for use at the annual meeting of shareholders to be held on Tuesday, April 26, 2011, or at any adjournments thereof.

        At the close of business on March 1, 2011, the record date for shareholders entitled to notice of and to vote at the meeting, there were outstanding 26,388,998 shares of the Company's common stock. There were no preferred shares outstanding. All holders of common stock are entitled to one vote for each share of stock held by them.

        The presence of a majority of the outstanding common stock represented in person or by proxy at the meeting will constitute a quorum. Shares represented by proxies that are marked "abstain" will be counted as shares present for purposes of determining the presence of a quorum. Proxies relating to "street name" shares that are voted by brokers on some matters will be treated as shares present for purposes of determining the presence of a quorum, but will not be treated as shares entitled to vote at the annual meeting on those matters as to which authority to vote is withheld by the broker ("broker non-votes"). Please note that if you hold your shares through a broker, your broker may no longer vote your shares on certain matters in the absence of your specific instructions as to how to vote. In order for your vote to be counted, please make sure that you submit your vote to your broker.

        Election of the three director nominees requires the affirmative vote of a majority of the votes cast for the election of directors at the annual meeting. Votes may be cast in favor of or withheld with respect to all of the director nominees, or any of them. Abstentions and broker non-votes are not treated as votes cast and therefore will not affect the outcome of the election of directors. An incumbent director nominee who receives a greater number of votes "withheld" than "for" in an election is required to tender his resignation to the board, and the resignation will be accepted or rejected by the board as more fully described in Election of Directors.

        The ratification of the appointment of the auditors and approval of the advisory say-on-pay resolution on executive compensation will be decided by the affirmative vote of the holders of a majority of the shares present in person or represented by proxy at the meeting and entitled to vote. Abstentions will be counted; they will have the same effect as a vote against the matter. Broker non-votes will be disregarded.

        The say-on-pay frequency option that receives the highest number of votes cast by holders of shares present in person or represented by proxy at the meeting and entitled to vote will be the advisory shareholder selection for the frequency of holding executive compensation votes. Abstentions and broker non-votes will have no impact on the selection of the frequency option.

        Any shareholder giving a proxy may revoke it before the meeting whether delivered by telephone, Internet or through the mail, by using the telephone voting procedures, the Internet voting procedures or by mailing a signed instrument revoking the proxy to: Corporate Secretary, Valmont Industries, Inc., One Valmont Plaza, Omaha, Nebraska 68154-5215. To be effective, a mailed revocation must be received by the Corporate Secretary before the date of the meeting and a telephonic or Internet revocation must be submitted by 12:00 p.m. Eastern Time on April 25, 2011. A shareholder may attend the meeting in person and at that time withdraw the proxy and vote in person.

        As permitted by Securities and Exchange Commission rules, Valmont is making this proxy statement and its annual report available to its stockholders electronically via the Internet. On March 17, 2011, we mailed to many of our shareholders a Notice of Internet Availability of Proxy Materials containing instructions on how to access this proxy statement and our annual report and to vote online. If you received such a Notice by mail, you will not receive a printed copy of the proxy

materials in the mail. Instead, the Notice instructs you on how to access and review all of the important information contained in the proxy statement and annual report. The Notice also instructs you on how you may submit your proxy over the Internet. If you received a Notice by mail and would like to receive a printed copy of our proxy materials, you should follow the instructions for requesting such materials contained on the Notice.

        The Securities and Exchange Commission's rules permit us to deliver a single Notice or set of this proxy statement and our annual report to one address shared by two or more of our shareholders. This delivery method is referred to as "householding" and can result in significant cost savings. To take advantage of this opportunity, we have delivered only one Notice or set of this proxy statement and our annual report to multiple shareholders who share an address, unless we received contrary instructions from such shareholders prior to the mailing date. We agree to deliver promptly, upon written or oral request, a separate copy of the Notice or a set of this proxy statement and our annual report, as requested, to any shareholder at the shared address to which a single copy of those documents was delivered. If you prefer to receive separate copies of the Notice or this proxy statement and our annual report, contact Broadridge Financial Solutions, Inc. at 1.800.542.1061 or in writing at Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New York 11717.

Corporate Governance

        Valmont is committed to having strong corporate governance principles. The board of directors believes such principles are essential to the effective operation of Valmont's businesses and to maintaining Valmont's integrity in the marketplace.

Overview

        The board of directors has adopted corporate governance principles which are set out in the "Investor Relations" section of the Company's website at www.valmont.com. The following corporate governance documents also appear on the Company's website and these documents and the Company's Corporate Governance Principles are available in print to any shareholder upon request to the Corporate Secretary:

•

Code of Business Conduct



•

Code of Ethics for Senior Officers



•

Audit Committee Charter



•

Human Resources Committee Charter



•

Governance and Nominating Committee Charter



•

International Committee Charter



•

Procedures for bringing concerns or complaints to the attention of the Audit Committee

        The board met six times during 2010. All directors attended at least 75% of all board meetings and all meetings of Committees on which the director served. Directors are encouraged to attend the annual shareholders' meeting and all Company directors attended the 2010 annual shareholders' meeting. The board of directors periodically reviews the Corporate Governance Principles and any changes are communicated to shareholders by posting them on the Company's website.

Board Leadership Structure and Risk Oversight

        The board's leadership structure consists of a Chairman and a Lead Director. The Chairman is also the Chief Executive Officer. The board believes this combined role promotes unified leadership and direction for the board and executive management and allows for a single clear focus for the chain of command to execute the Company's strategic initiatives and business plans. The board does not believe the combined role adversely affects the independence of the board. All board members have substantial business experience and all board members, with the exception of the Chief Executive Officer, are independent within the meaning of the Company's corporate governance principles and the NYSE Listing Standards. The Company's independent directors meet in executive session without management present at every board meeting. The Chief Executive Officer periodically updates the board on succession planning for key officers and the board reviews CEO succession planning in detail annually at its July meeting.

        The board has established the position of Lead Director. The position is filled by an independent director. The lead director presides at executive sessions of the independent directors, serves as a liaison between the Chairman and the independent directors, and has the ability to call meetings of the independent directors. Interested parties who wish to contact the board of directors or the lead director may communicate through the lead director by writing to: Lead Director of Valmont Board of Directors, Valmont Industries, Inc., One Valmont Plaza, Suite 601, Omaha, Nebraska, 68154-5215.

        The board has oversight responsibility for risks affecting the Company. The board has delegated risk oversight with respect to operational, compliance and financial matters to the Audit Committee

4

---

and has delegated risk oversight with respect to compensation matters to the Human Resources Committee.

Governance Actions

        The board of directors and board committees have taken a number corporate governance actions. The more significant actions include:

•

The board of directors has approved bylaws which adopt a majority voting system for the election of directors.



•

The board of directors has adopted director stock ownership guidelines. The guidelines provide that directors should own Valmont common stock with a value at least equal to five times the director's annual retainer. Directors have five years after joining the board to meet the guidelines.



•

The board of directors has adopted an executive compensation recoupment policy. The policy generally provides that if Valmont is required to restate its financial statements for a period after fiscal 2006, the board of directors may require reimbursement of all or any part of any cash or stock award granted in December 2007 or later based on an incentive plan that relates to the performance of Valmont, if the employee engaged in certain conduct which caused or contributed to the need for the restatement. The board of directors has the right to apply the reimbursement policy in all cases to the Chief Executive Officer, Chief Financial Officer and Group President (if the conduct occurred in the Group) if an employee engaged in the designated conduct.



•

The Human Resources Committee has engaged Frederick W. Cook & Co. ("Cook") as its independent executive compensation consulting firm. The Company does not engage Cook for any services beyond their support of the Human Resources Committee.



•

The board of directors in December 2005 did not extend the term of the Company's expiring Shareholder Rights Plan, effectively terminating the Shareholder Rights Plan.

Board Independence

        The board of directors is composed of a majority of independent directors. The board has established independence standards for Valmont's directors. These standards are set forth below and are contained in the Company's Corporate Governance Principles and follow the director independence standards established by the New York Stock Exchange:

•

A director will not be independent if, within the preceding three years (1) the director was employed by Valmont or an immediate family member of the director was an executive officer of Valmont, (2) a Valmont executive officer was on the compensation committee of the board of directors of a company which employed the Valmont director as an executive officer or which employed an immediate family member of the director as an executive officer, or (3) the director or the director's immediate family member received more than $120,000 during any twelve-month period in direct compensation from Valmont (other than director and committee fees).



•

A director will not be independent if (1) the director is an executive officer or an employee, or the director's immediate family member is an executive officer, of another company and (2) the other company made payments to, or received payments from, Valmont for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1,000,000 or 2% of either (i) such other company's consolidated gross revenues or (ii) Valmont's consolidated gross revenues.

5

---

•

A director will not be independent if (1) the director or an immediate family member is a current partner of Valmont's independent auditor, (2) the director is an employee of Valmont's independent auditor, (3) the director has an immediate family member who is a current employee of Valmont's independent auditor who personally works on Valmont's audit, or (4) the director or an immediate family member was within the last three years a partner or employee of Valmont's independent auditor and personally worked on Valmont's audit within that time.



•

For relationships not covered by the foregoing standards, the determination of whether the relationship is material or not, and therefore whether the director would be independent or not, is made by the directors who satisfy the above independence standards. The board's determination of each director's independence is disclosed annually in the Company's proxy statement.



•

Tax-exempt organizations to which Valmont makes contributions shall not be considered "companies" for purposes of these independence standards. However, Valmont will disclose in its annual proxy statement any such contribution which it makes to a tax-exempt organization in which a director serves as an employed executive officer if, within the preceding three years, contributions in any fiscal year exceeded the greater of $1,000,000 or 2% of such tax-exempt organization's consolidated gross revenues.

        The board has determined that all directors except Mr. Bay (the Company's Chief Executive Officer) have no material relationship with the Company and are independent within the meaning of the Company's Corporate Governance Principles and the NYSE listing standards. The directors determined that an aircraft interchange agreement and related agreements between the Company and Mutual of Omaha (an insurance and financial services company with $5.3 billion revenue), and sales of products to a subsidiary of Peter Kiewit & Sons, Inc. (a construction company with $9.9 billion revenue), were immaterial.

Audit Committee

        The current members of the Audit Committee are directors Scott (Chairman), den Daas and Neary. All members of the Audit Committee are independent within the meaning of the Company's Corporate Governance Principles and the listing standards of the NYSE. The board has determined that all members of the Audit Committee are qualified as audit committee financial experts within the meaning of SEC regulations. The Audit Committee acts under a written charter, adopted by the board of directors, a copy of which is available on the Company's website. The report of the Audit Committee is included in this proxy statement.

        The Audit Committee met six times during 2010. The Audit Committee assists the board by reviewing the integrity of the financial statements of the Company; the qualifications, independence and performance of the Company's independent auditors and internal auditing department; and compliance by the Company with legal and regulatory requirements. The Audit Committee has sole authority to retain, compensate, oversee and terminate the independent auditor. The Audit Committee reviews the Company's annual audited financial statements, quarterly financial statements, and filings with the Securities and Exchange Commission. The Audit Committee reviews reports on various matters, including critical accounting policies of the Company, significant changes in the Company's selection or application of accounting principles, and the Company's internal control processes. The Audit Committee pre-approves all audit and non-audit services performed by the independent auditor. The Audit Committee has a written policy with respect to its review and approval or ratification of transactions between the Company and a director, executive officer or related person. The Audit Committee reviews and approves or disapproves any material related person transaction, i.e., a transaction in which the Company is a participant, the amount involved exceeds $120,000, and a director, executive officer or related person has a direct or indirect material interest. The Audit

6

Committee reports to the board of directors any such material related person transaction that it approves or does not approve.

Human Resources Committee

        The current members of the Human Resources Committee are directors Barton (Chairman), Lewis, Stinson and Neary. All members of the Human Resources Committee are independent within the meaning of the Company's Corporate Governance Principles and the listing standards of the NYSE.

The report of the Human Resources Committee is included in this proxy statement.

        The Human Resources Committee met three times during 2010. The Human Resources Committee assists the board in fulfilling its responsibilities relating to compensation of the Company's directors, executive officers and other selected employees. The Committee has responsibility for reviewing, evaluating and approving compensation plans, policies and programs for such persons. The Human Resources Committee annually reviews and approves corporate goals and objectives for the chief executive officer's compensation and evaluates the chief executive officer's performance in light of those goals and objectives. The Human Resources Committee, together with the other independent directors, determines the chief executive officer's compensation. The Committee also approves incentive compensation plans and equity based plans for executive officers and other selected employees. The Human Resources Committee has established stock ownership guidelines for company officers, which are described in this proxy statement in Compensation Discussion and Analysis. The board, upon recommendation of the Human Resources Committee, established during 2007 stock ownership guidelines for Company directors, which are described in this proxy statement in Corporate Governance—Governance Actions.

Governance and Nominating Committee

        The current members of the Governance and Nominating Committee are directors Lewis (Chairman), Barton and Randt. All members of the Governance and Nominating Committee are independent within the meaning of the Company's corporate governance principles and the listing standards of the NYSE. The Governance and Nominating Committee acts under a written charter, adopted by the board of directors, a copy of which is available on the Company's website.

        The Governance and Nominating Committee met four times during 2010. The Governance and Nominating Committee assists the board by (1) recommending to the board Corporate Governance Principles for the Company, and (2) identifying qualified candidates for membership on the board, proposing to the board a slate of directors for election by the shareholders at each annual meeting, and proposing to the board candidates to fulfill vacancies on the board. The Governance and Nominating Committee coordinates the annual self-evaluation by the directors of the board's performance and the CEO's performance and the annual performance evaluation by each committee of the board. The Governance and Nominating Committee oversees the Company's process for consideration of nominees to the Company's board of directors. The process is described in the Director Nomination Process.

reviews international government and financial issues that have a significant effect on the Company, and (3) acts as a sounding board for the Chief Executive Officer and the management team concerning business opportunities and risks, including economic, political and social trends, in international markets.

Director Nomination Process

        The Governance and Nominating Committee considers candidates for board membership suggested by its members and other board members, as well as management and shareholders. The Committee may also retain a third-party executive search firm to identify candidates from time to time. A shareholder who wishes to recommend a prospective nominee for board membership should notify the Company's Corporate Secretary in writing at least 120 days before the annual shareholder meeting at which directors are to be elected and include whatever support material the shareholder considers appropriate. The Governance and Nominating Committee will also consider nominations by a shareholder pursuant to the provisions of the Company's bylaws relating to shareholder nominations as described in Shareholder Proposals.

        The Governance and Nominating Committee makes an initial determination as to whether to conduct a full evaluation of the candidate once it has identified a prospective nominee. This initial determination is based on whatever information is provided to the Committee as well as other information available to or obtained by the Committee. The preliminary determination is based primarily on the need for additional board members to fill vacancies or expand the size of the board and the likelihood that the prospective nominee can satisfy the evaluation factors described below. If the Committee determines that additional consideration is warranted, it may request a third-party search firm or other third parties to gather additional information about the prospective nominee.

        The Committee evaluates each prospective nominee in light of the standards and qualifications set out in the Company's Corporate Governance Principles, including:

•

Background, including demonstrated high standards of ethics and integrity, the ability to have sufficient time to effectively carry out the duties of a director, and the ability to represent all shareholders and not a particular interest group.



•

Board skill needs, taking into account the experience of current board members, the candidate's ability to work in a collaborative culture with other board members, and the candidate's qualifications as independent and qualifications to serve on the Audit Committee, Human Resources Committee and/or Governance and Nominating Committee.



•

Diversity, including the extent to which the candidate reflects the composition of Company shareholders and other constituencies.



•

Business experience, which should reflect a broad experience at the policy-making level in business, government or education, both domestically and internationally.

        The Committee also considers such other relevant factors as it deems appropriate. In connection with the evaluation, the Committee determines whether to interview the prospective nominee, and if warranted, one or more members of the Committee interview prospective nominees in person or by telephone. After completing this evaluation process, the Committee makes a recommendation to the full board as to the persons who should be nominated by the board, and the board determines the nominees after considering the recommendations of the Committee. The Committee assesses the effectiveness of its policies in determining nominees for director as part of its annual performance valuation.

ITEM 1:    BOARD OF DIRECTORS AND ELECTION OF DIRECTORS

        The Company's board of directors is presently composed of eight members. The board is divided into three classes and each class serves for three years on a staggered term basis.

        Three directors have terms of office that expire at the 2011 annual meeting: Walter Scott, Jr., Clark Randt, and Mogens Bay. These three directors have been nominated by the board of directors, upon recommendation of the Governance and Nominating Committee, for re-election to three-year terms.

        The Company bylaws provide that directors are elected by the affirmative vote of a majority of the votes cast with respect to the director at the meeting, unless the number of nominees exceeds the number of directors to be elected (a contested election), in which case directors will be elected by the vote of a plurality of the shares present and entitled to vote at the meeting. If a nominee is not elected and the nominee is an incumbent director, the director is required to promptly tender his resignation to the board. The Governance and Nominating Committee will consider the tendered resignation and recommend to the board whether to accept or reject the resignation or whether other action should be taken. The board will act on the tendered resignation and publicly disclose its decision within 90 days from the certification of the election results. The director who tenders his resignation will not participate in the Committee's recommendation or the board action regarding whether to accept or reject the tendered resignation.

        The Company's policy on director retirement, as expressed in the Corporate Governance Principles, provides that a director will not be nominated to a new term if he or she would be over age 73 at the time of election. The board evaluated its skill needs and concluded not to apply the policy to Mr. Scott, a highly-experienced director with extensive business experience, for the 2011 director election.

        The shares represented by the enclosed proxy will be voted for the election of the nominees named above. In the event any of such nominees becomes unavailable for election, the proxy holders will have discretionary authority to vote the proxies for a substitute. The board of directors has no reason to believe that any such nominee will be unavailable to serve.

        The following discussion provides information about the three nominees, and the five directors whose terms expire in 2012 and 2013, including ages, years of service, business experience, and service on other boards of directors within the past five years. Information is also provided concerning each person's specific experience, qualifications, attributes or skills that led the board to conclude that the person should serve as a director of the Company.

Compensation Discussion and Analysis

        General.    The following compensation discussion and analysis provides information which the Human Resources Committee of the Board of Directors (the "Committee") believes is relevant to an assessment and understanding of Valmont's executive compensation programs. This discussion should be read in conjunction with the summary compensation table and related tables in this proxy statement and the "Human Resources Committee" information in the corporate governance section in this proxy statement.

        Compensation Objectives and Strategies.    Valmont's executive compensation programs, policies and practices are approved by the Committee. The compensation programs apply to executive officers and to certain key employees who are not executive officers. The programs specifically apply to the executive officers listed in the summary compensation table (named executive officers). The Committee has established Valmont compensation objectives pursuant to which Valmont's compensation programs are designed to:

•

target total compensation amounts at competitive market levels to attract, retain, motivate and reward the performance of executive officers and other key employees;



•

direct management focus to the long-term growth of the Company, enhance shareholder value, and ensure that executive officers have significant ownership without increasing dilution over acceptable levels; and



•

pay for performance by providing performance based incentive plans measured against established targets, with no guaranteed minimum payment provisions, and with total awards above median market levels for exceeding performance targets.

        The Committee established compensation strategies designed to carry out the compensation objectives, including:

•

total compensation evaluated by position, on an annual basis, against like positions in companies of similar sales volume, according to data provided by outside compensation consultants; and



•

base pay, annual incentives and long-term incentives targeted at median market levels, with the opportunity for annual and long-term incentives at the 75th percentile or higher for significantly exceeding performance targets.

The Committee in December 2006 engaged Frederic W. Cook & Co., Inc. ("Cook") as the Committee's independent executive compensation consultant. Cook reports directly to the Committee and provides advice to the Committee on the structure and amounts of executive and director compensation. Cook provides no other services to the Company.

        Compensation Processes and Practices.    The Committee follows certain processes and practices in connection with the structure and implementation of executive compensation plans.

•

The elements of compensation, and total compensation, are reviewed against general industry survey data and a peer group developed by Cook and approved by the Committee. The Committee uses the survey data and peer group information to assess the competitiveness of compensation levels and pay mix for the CEO, CFO and other executives.



•

The Committee used as its primary benchmark a general industry Hewitt Survey of 117 companies which Cook adjusted to provide representative compensation levels for companies within a range of Valmont's annual revenues. The adjusted revenue size range of the companies in the Hewitt Survey was approximately $1.8 billion. Valmont's 2010 revenues were approximately $2.0 billion. The competitive medians referenced below for base salary, annual incentives and long-term incentives are the competitive medians based on the Hewitt Survey data.



•

The Committee also used a peer group developed by Cook in 2008 as a supplemental benchmark of CEO and CFO pay levels. Cook advised that, due to the differences in the jobs that the individuals reported in the proxies of the peer group companies, consistent and reliable comparable compensation information was available only for the CEO and CFO. The peer group for 2010 consisted of the following thirteen companies:

•

The Company's size and market cap relative to the peer group for the 2010 analysis was as follows: The Company's revenues approximated the median of the peer group and the Company's market cap was between the peer median and the peer 75^th percentile.



•

The Committee also reviews a tally sheet with respect to the total compensation of each named executive officer and each group president. The Committee utilizes tally sheets as a reference point in order to ensure that the Committee has a comprehensive picture of the compensation paid and payable to each executive officer. The Committee uses market data provided by its independent compensation consultant as the primary factor in executive compensation decisions and the tally sheets are not determinative with respect to any particular element of compensation.



•

The compensation programs provide for both cash and equity elements. Base salary and annual incentives are paid in cash. Long-term incentives comprised of performance shares are paid in cash for executives who have met their stock ownership guidelines, and are paid 50% in cash and 50% in equity for other executives. Stock options are settled in equity.



•

The Committee determines the mix of cash and equity compensation. The Committee has no pre-established policy for the allocation between either cash and non-cash or short-term and long-term incentive compensation. The Committee reviews information provided by compensation consultants to determine the appropriate level and mix of incentive compensation. The Committee believes that a majority of an executive's overall compensation should be incentive-based and that each executive who has not attained applicable stock ownership guidelines should receive at least 50% of long-term compensation in equity.



•

The structure of all incentive compensation plans is reviewed periodically to assure their linkage to the current objectives and strategies and performance goals.

12

---

•

The Committee's policy is to establish base salary, annual incentives and long-term incentives with targets at the competitive median level and potential payouts of incentives up to 200% of target for significantly exceeding performance targets. The annual incentives and long-term incentives are established for each executive officer by using a percentage of base salary that results in the competitive target median for the executive. There are no material differences in compensation policies with respect to individual executive officers.



•

The Company's programs have been designed so that compensation paid to executive officers will be deductible under the Internal Revenue Code's compensation limits for deductibility, although the Committee may from time to time make restricted stock awards or discretionary cash awards in excess of the deductibility limits. Executive compensation generally produces ordinary income to the executive and a corresponding tax deduction for Valmont, except for amounts deferred under Valmont's qualified and related nonqualified plan, amounts subject to future vesting, and amounts related to stock awards which are subject to special accounting and tax provisions.

        Elements of Compensation.    Valmont's executive compensation is based on four components, each of which is intended to support the overall compensation philosophy.

•

The four components are base salary, annual incentives, long-term performance incentives, and equity incentives. For 2010, base salary accounted for approximately 34% of the total compensation of the named executive officers and incentive compensation accounted for approximately 66% of such total compensation.



•

Valmont's executive officers do not have employment agreements.



•

Valmont's executive officers do not have agreements providing for special payments in the event of a termination of employment or a change-of-control of Valmont. Valmont's equity incentive plans do provide for accelerated vesting of non-vested amounts in the event of a change-of-control. See Potential Payments Upon Termination or Change-in-Control.



•

Valmont does not have a pension plan. Valmont's executive officers do participate in its 401(k) Plan and also participate in the related non-qualified supplemental benefit plan.



•

Valmont does not maintain a perquisite program for its executive officers. Amounts relating to the Chief Executive Officer's use of Company aircraft for personal travel are included in the summary compensation table.



•

Valmont has an executive compensation recoupment policy described on page 5.

        Base Salary.    Base salary is targeted at the competitive median level. Competitive median levels are provided by Cook based on the primary benchmark survey prepared by Hewitt. Base salary is intended to compensate the executive for satisfying the requirements of the position. Salaries for executive officers and other key employees are reviewed by the Committee on an annual basis and may be changed based on the individual's performance or a change in competitive pay levels in the marketplace.

        The Committee reviews with the Chief Executive Officer an annual salary plan for the Company's executive officers and other key employees (other than the Chief Executive Officer). The salary plan is modified as deemed appropriate and approved by the Committee. The annual salary plan is developed by the Company's Human Resources staff, under the ultimate direction of the Chief Executive Officer, and is based on national surveys of companies with similar characteristics and on performance judgments as to the past and expected future contributions of the individual executive. The Committee reviews and establishes the base salary of the Chief Executive Officer based on competitive compensation data provided by Cook and the Committee's assessment of his past performance, his leadership in establishing performance standards in the conduct of the Company's business, and its

13

---

expectation as to his future contribution in directing the long-term success of the Company and its businesses.

        The Committee set the Chief Executive Officer's base salary at $880,000 for 2010. The Committee continued the Company's combined matching contribution under the Valmont Employees Retirement Savings Plan (a 401(k) plan) and related Restoration Plan (a non-qualified plan in place since 2002 designed to restore benefits otherwise limited by IRS regulations). The contribution is 15% of covered compensation (salary, bonus and cash incentives) for Mr. Bay, Mr. McClain and Mr. Meaney and 4.5% for other executive officers. The Committee set the contribution percentage for the top three executive officers at a higher rate due to the need to retain their critical services and the absence of any pension plan. The Company's contributions to such plans for 2010 compensation for the named executive officers (which matched the amounts contributed by such executive officers) are set forth in the Non-Qualified Deferred Compensation table.

        Based on the factors described above, the Committee made no changes to the base salaries from 2010 to 2011 for the named executive officers (other than a $12,012 increase for Mr. McClain, a $7,364 increase for Mr. Graboski and a $24,500 increase for Mr. Desigio) and such base salaries are as follows: Mr. Bay, $880,000; Mr. McClain, $441,012; Mr. Meaney, $325,105; Mr. Graboski, $270,364; and Mr. Desigio, $269,500. For 2011, base salaries of Messrs. Bay, McClain, Graboski and Desigio were 96%, 97%, 94%, and 113% of the competitive median level. There was no comparable competitive compensation information available for Mr. Meaney's position.

        Annual Incentives.    The Company's short-term incentives are paid pursuant to programs established under the shareholder approved Executive Incentive Plan. The Committee believes that the annual incentive of officers should be based on optimizing profits. Accordingly, the programs provide for target performance levels based on the Company's earnings per share performance for executive officers, and on the respective business unit's operating income for business unit senior officers; the business unit plans included a gross working capital modifier. Annual incentives are targeted at the competitive median level. Competitive median levels are determined based on the primary benchmark survey provided by Cook. For 2010, each named executive officer's annual incentive opportunity ranged from 0% to 200% of the median targeted incentive, depending on the level of achievement of the Company's earnings per share performance goals. The annual incentive targets for Messrs. Bay, McClain, Graboski and Desigio were 98%, 90%, 79% and 127% of the competitive median level. For executive officers' 2010 annual incentives, a target incentive was established ranging from 30% to 100% of base salary, and performance goals were set based on earnings per share performance; the percentage of base salary for the named executive officers was: Mr. Bay 100%; Mr. McClain 60%; Messrs. Meaney, Graboski and Desigio 40%. A minimum threshold level of earnings per share had to be attained before any incentive was earned by an executive officer. Payout under the plan to any executive officer was capped at two times the target incentive and three times the target incentive for the group presidents. Participants, thresholds and specific performance levels are established by the Committee at the beginning of each fiscal year. The Committee may in addition award discretionary non-incentive based bonuses to an executive officer based on performance in a particular year; no discretionary awards were made to named executive officers with respect to performance in 2006 through 2009. The Committee granted a special individual 2010 discretionary performance award of $100,000 to Mr. Desigio (50% in cash and 50% in restricted stock) in recognition of his work on the Delta acquisition completed in 2010.

        The Committee approved participation, including executive officers, in the short-term incentive program for 2010. The threshold earnings per share performance for executive officers was set at earnings per share of $4.73, the target annual incentive (the amount of which for each executive officer was based on the competitive median pursuant to the primary benchmark survey provided by Cook) was set at $5.73, with a two times target incentive (the amount of which represented a capped payout potential based on the Committee's view of earning per share which would significantly exceed target)

14

---

set at $6.59. The Committee determined in 2010 that non-recurring acquisition-related costs, such as those incurred in connection with the Delta acquisition, would be excluded in determining performance factors under the incentive plans; the exclusion of $.62 of Delta acquisition costs had no effect on the payouts under the annual incentive plan or the long-term incentive plan for 2010. Based on the $4.19 earnings per share performance levels achieved during 2010, no short-term incentive payouts were made to named executive officers for 2010. In February 2011, the Committee selected the participants and established the performance goals for the 2011 annual incentive program; the performance goals for named executive officers in 2011 are again based on earnings per share performance.

        Long-Term Performance Incentives.    Long-term performance incentives for senior management employees are provided through long-term performance share programs established under the shareholder approved Executive Incentive Plan and through equity awards under the shareholder approved Stock Plans. Long-term performance incentives (long-term performance share plan and equity awards) are targeted at competitive median levels. Competitive median levels are determined based on the primary benchmark survey provided by Cook. For the three-year award cycle ended in 2010, each named executive officer's long-term incentive opportunity ranged from 0% to 200% of the median targeted incentive, depending on the level of achievement of the Company's performance goals. The long-term incentive targets (including both performance shares and options) for Messrs. Bay, McClain, Graboski and Desigio were 100%, 93%, 43%, and 119% of the competitive median level. The payments made to these officers, set forth below, all fell within this targeted range and were two times target based on the Company's three-year average ROIC of 13.4% and cumulative three-year compound operating income growth of 18.3%.

        The current long-term performance programs operate on three-year award cycles. The Committee selects participants, establishes target awards, and determines a performance matrix (which, for the award cycle ending in 2010, was based on average return on invested capital or "ROIC" and cumulative compound operating income growth or "OIG", weighted 60% ROIC and 40% OIG, at the beginning of each award cycle. ROIC of less than 8.0% coupled with OIG of less than 6% resulted in no incentive payment. ROIC of 9.5% coupled with OIG of 10% generated a one times target incentive payment (based on the competitive median established by Cook's primary benchmark survey). ROIC of 13% coupled with OIG of 17% generated a two times target incentive payment (based on the Committee's judgment as to performance substantially exceeding the target levels). Targets for the 2008-2010 award cycle were established based on a predetermined percentage ranging from 25% to 100% of base salary, which amount is converted to performance shares valued at the Company's stock price at the beginning of the performance period (which for the 2008-2010 performance period was a thirty-day average of $84.39). The percentages for the named executive officers was: Mr. Bay, 100%; Mr. McClain, 50%; Mr. Meaney, 30%; and Messrs. Graboski and Desigio, 25%. The performance matrix provides for the performance shares to be increased or decreased in number based on greater or lesser levels of performance. Earned performance shares are then valued at the Company's stock price at the end of the performance period (which for the 2008-2010 performance period was a thirty-day average of $83.37); consequently, payouts may be higher or lower based on the Company's stock price performance during the award cycle. Performance incentives are generally forfeited if a participant leaves the Company before the end of the performance cycle. Prorated awards may be earned based on performance results in the event of death, disability, normal retirement, termination of employment without cause, or a change in control. Earned performance shares are capped at two times the target number of performance shares. The Committee approves the number of performance shares to be paid following a review of results at the end of each performance cycle. Awards may be paid in cash or in shares of common stock or any combination of cash and stock; participants who have not attained applicable stock ownership guidelines receive 50% of the award in common stock.

        The Committee selected the participants, including executive officers, for participation in the award cycle ending in 2010. Based on the above described ROIC and OIG performance goals

15

---

established by the Committee, the Company's three-year average 13.4% ROIC and three-year cumulative compound operating income growth of 18.3% for the three-year period ended in 2010, and the change in the Company's stock price during the performance period (from $84.39 to $83.37), long-term incentive payments were earned by the named executive officers as follows: Mr. Bay, $1,738,721; Mr. McClain, $410,972; Mr. Meaney, $192,705; Mr. Graboski, $125,959; and Mr. Desigio, $107,169. All awards to the named executive officers were paid in cash, except 50% of the awards to Messrs. Graboski and Desigio were paid in stock. In February 2010, the Committee selected the participants and established the performance goals for the 2010-2012 award cycle; the performance goals for the cycle ending in 2012 are again based on a combination of growth in operating income and return on invested capital, with targets established based on a percentage of base salary ranging from 25% to 150%. The weighting of performance factors for the 2010-2012 award cycle is 40% ROIC and 60% OIG. The performance goals for the 2011-2013 award cycle, established by the Committee in February 2011, are again based on a combination of growth in operating income and return on invested capital.

        Stock Incentives and Ownership Guidelines.    The board of directors, upon recommendation of the Committee, established during 2001 stock ownership guidelines for senior management. The guidelines require an equity position having a value of six times base salary for the Chief Executive Officer, five times base salary for the Chief Financial Officer and four times base salary for corporate officers and group presidents. The individuals are expected to achieve the targeted equity positions within three to five years. The Chief Executive Officer, Chief Financial Officer and the other named executive officers currently meet these targets, except for Mr. Graboski who joined the Company in August 2007 and Mr. Desigio who joined the Company in April 2008.

        Long-term stock incentives are provided through grants of stock options and restricted stock to executive officers and other key employees pursuant to the shareholder approved 2002 and 2008 Stock Plans. The stock component of compensation is intended to retain and motivate employees to improve long-term shareholder value. Such grants for executive officers were in 2008, 2009 and 2010 made at the regularly scheduled Committee meeting in December of each year. Stock options are granted at the market value on the date of grant and have value only if the Company's stock price increases. Stock options granted during 2010 vest beginning on the first anniversary of the grant in equal amounts over three years and expire seven years after the date of grant. Employees must be employed by the Company at the time of vesting in order to exercise the options. Options also vest on death, disability and change-of-control; if an employee retires on or after age 62, options continue to vest for three years.

        The Committee establishes the number and terms of the options granted under the stock plans. The Committee established the terms and provisions of stock options based on industry standards as provided to the Committee by its independent compensation consultant. The Committee established the number of options to each executive officer so that the aggregate long-term incentive compensation would be targeted at competitive median levels. The value used in determining the number of stock options granted to each executive officer was computed in accordance with FASB Accounting Standards Codification Topic 718, which is described in footnote 10 to the Company's consolidated financial statements. The Committee encourages executives to build a substantial ownership investment in the Company's common stock. The table on page 3 reflects the ownership position of the directors and executive officers at March 1, 2011. Outstanding performance by an individual executive officer is recognized through larger option grants. The Committee, in determining grants of stock options under the stock plans, also reviews and considers the executive's history of retaining shares previously obtained through the exercise of prior options. For 2010, stock options were granted to the named executive officers with a fair market value of a percentage of base salary: Mr. Bay, 120%; Mr. McClain, 70%; Mr. Graboski, 35%; and Mr. Desigio, 25%. Mr. Meaney, who plans to retire in 2011, did not receive an option grant. The amounts were established so that aggregate long-term

16

---

incentive compensation would be targeted at competitive median levels. Competitive median levels are determined based on the primary benchmark survey provided by Cook.

        The Committee granted options for an aggregate of 223,281 shares to 138 employees in December 2010, including options to named executive officers as described below. In addition, the Committee granted restricted stock units for an aggregate of 10,811 shares to 42 international employees during 2010.

        The Committee determined in December 2007 that the equity grants to executive officers should be primarily in options in order that the awards be performance based. In December 2010, the Committee granted 44,489 stock options to Mr. Bay, 12,651 to Mr. McClain, 3,878 to Mr. Graboski, and 2,580 to Mr. Desigio. The vesting provisions for these option grants are described on page 20. The Committee determined that such grants were appropriate long-term incentives, based on market data and the Committee's review of each executive's performance.

        The Committee has stated its belief that the programs described above provide compensation that is competitive with comparable companies, link executive and shareholder interests and provide the basis for the Company to attract and retain qualified executives. The Committee has indicated that it will continue to monitor the relationship among executive compensation, the Company's performance and shareholder value.

Compensation Risk Assessment

        The Human Resources Committee in February 2011, with its independent compensation consultant, conducted a risk assessment of the Company's compensation programs. The Committee believes the programs are designed to promote long-term value creation and do not motivate imprudent risk taking. The Company sets performance goals that are reasonable in light of past performance and market conditions. The annual and long-term incentive plans for executives and senior management use an aggregate of three or more company-wide performance metrics which provide for sliding scale incentives rather than an all-or-nothing approach; all such incentives have thresholds before they are paid and all are capped. The long-term incentives, consisting of performance shares and options, have a three-year performance period or vesting period. The Company has a stock retention policy which requires retention of equity awards until stock ownership guidelines are met. The Company also has an executive clawback policy in the event of financial restatements due to fraud.

Human Resources Committee Report

        The Human Resources Committee has reviewed and discussed the Compensation Discussion and Analysis with management and, based on such review and discussion, has recommended to the board that the Compensation Discussion and Analysis be included in this Proxy Statement.

Equity Compensation Plan Information

        The following table provides information about the Company's common stock that may be issued upon exercise of options, warrants and rights under existing equity compensation plans as of December 25, 2010.

Potential Payments Upon Termination or Change-In-Control

        Valmont does not have employment agreements with its executive officers. Valmont also does not have special severance or change-in-control payment agreements with its executive officers.

        Valmont's executive officers may receive severance payments upon a termination of employment under Valmont's severance plan which is generally available to all administrative employees. The severance plan generally provides one week of salary for each year of service up to 26 weeks of salary. Valmont's executive officers would also be entitled to receive upon termination of employment amounts accumulated in their respective deferred compensation accounts, at the times and in the manner established for their respective accounts; such amounts are described in the Non-Qualified Deferred Compensation table.

        Valmont's stockholder-approved stock plans provide that all outstanding options become immediately exercisable in the event of a change-in-control and that all restrictions on restricted stock lapse in the event of such a change-in-control. A change-in-control, defined specifically in the plans, generally occurs if: (i) a person, entity or group (excluding Valmont plans) acquires 50% or more of Valmont's common stock or total voting power of Valmont's voting securities; (ii) incumbent directors or their replacements (whose election or nomination was approved by at least a majority of then incumbent directors) cease to constitute a majority of the board; (iii) a reorganization, merger, consolidation, or sale of substantially all of the company's assets occurs unless Valmont's shareholders prior to the transaction own after the transaction 50% or more of the voting power of Valmont's securities; and (iv) Valmont is liquidated or dissolved. Options granted in 2008 and subsequent years provide for continued vesting pursuant to the option terms if the optionee voluntarily retires on or after attaining age 62. If such a change-in-control or retirement had occurred on the last day of fiscal 2010, the incremental value (fair market value of company common stock on such date less exercise price) of unvested options held by the named executed officers would have been: Mr. Bay—$968,369; Mr. McClain—$ 292,399; Mr. Meaney—$74,014; Mr. Graboski—$120,429; and Mr. Desigio—$51,032; and the value of unvested restricted stock for Mr. Bay would have been $ 11,494,847. The unvested stock options for such individuals and the unvested restricted stock for such individuals are set forth in the Outstanding Equity Awards at Fiscal Year-End table. In addition, a pro rata portion (based on period of service and full period performance results) of the performance shares awarded under the long-term incentive plan may be earned in the event of death, disability, normal retirement, termination of employment without cause, or change-in-control. If such a change-in-control or retirement had occurred on the last day of fiscal 2010, the prorated value of the long-term incentive awards (based on target award numbers) which would have been payable to the named executive officers would have been: Mr. Bay—$1,486,487; Mr. McClain—$422,686; Mr. Meaney—$137,255; Mr. Graboski—$129,557; and Mr. Desigio—$86,232.

Audit Committee Report

        The Audit Committee (the "Committee") is appointed by the board of directors to assist the board by reviewing (1) the integrity of the Company's financial statements, (2) the qualifications, independence and performance of the Company's independent auditors and internal auditing department and (3) the compliance by the Company with legal and regulatory requirements. The Committee manages the Company's relationship with its independent auditors, who report directly to the Committee. The Committee has sole authority to retain, compensate, oversee and terminate the independent auditors. The Committee acts under a written charter, adopted by the board of directors, a copy of which is available on the Company's website at www.valmont.com.

        The Company's management is responsible for its financial reporting process and internal controls. The independent auditors are responsible for performing an independent audit of the Company's consolidated financial statements and issuing an opinion on the conformity of those audited financial statements with generally accepted accounting principles. The Committee oversees the Company's financial reporting process and internal controls on behalf of the board of directors.

        The Committee reviews the Company's annual audited financial statements, quarterly financial statements and filings with the Securities and Exchange Commission. The Committee reviews reports on various matters, including (1) critical accounting policies of the Company, (2) material written communications between the independent auditor and management, (3) the independent auditor's internal quality-control procedures, (4) significant changes in the Company's selection or application of accounting principles and (5) the effect of regulatory and accounting initiatives on the financial statements of the Company. The Committee also considered whether the provision of non-audit services provided by Deloitte & Touche LLP ("Deloitte"), the Company's independent auditors, to the Company during fiscal 2010 was compatible with the auditor's independence.

        The Committee reviewed and discussed the Company's audited financial statements for fiscal 2010 with both management and Deloitte. The Committee received from and discussed with Deloitte the written disclosures and the letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the Committee concerning independence. The Committee also discussed with Deloitte any matters required to be discussed by Statement on Auditing Standards No. 61, as amended, as adopted by the Public Company Accounting Oversight Board relating to communications between the audit committee and the independent auditors. Based on these reviews and discussions, the Committee recommended to the board of directors and the board has approved that the Company's audited financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 25, 2010.

Valmont has a stock retention policy for executive officers which requires retention of equity awards until the stock ownership guidelines are met.

Fiscal 2010 Compensation for Executive Officers

•

Base Salary.  The base salaries paid to Valmont's named executive officers in 2010 were unchanged from their base salaries in 2009.



•

Annual Incentives.  Annual incentives are performance-based. The annual incentives for 2010 were based on threshold, target and above-target increases in earnings per share. Since earnings per share did not increase in 2010, no annual incentives were paid for 2010.

•

Long-Term Incentives.  Long-term incentives are performance-based. The three-year performance period which ended in 2010 based long-term incentives on a combination of three-year average ROIC (return on invested capital) and three-year growth in OIG (cumulative compound operating income growth). The Human Resources Committee established in February 2008 the targets for the three-year performance cycle ending in 2010. The Committee at that time looked at the average ROIC for the three years ended in 2007 of 10.9%, and the operating income for 2007 of $155.6 million, which was a record for the company. Incentive targets were established for the 2008-2010 award cycle based on improvements in those results. The Company's outstanding performance in 2008 and 2009 more than offset the below-target performance of 2010. The three-year average ROIC of 13.4% and the three-year OIG growth of 18.3% produced 2010 long-term incentive payouts for executive officers of two times target.



•

Stock Options.  The Human Resources Committee established the terms and provisions of stock options granted in 2010 based on industry standards as provided by its independent compensation consultant. The number of options granted to each executive officer was established so that the aggregate long-term incentive compensation would be targeted at competitive median levels. Information on the stock options granted to named executive officers during 2010 is at Grants of Plan Based Awards for Fiscal 2010.

        This advisory resolution, commonly referred to as a "say-on-pay" resolution, is nonbinding on the board of directors. Although non-binding, the board of directors and the Human Resources Committee will review and consider the voting results when making future decisions regarding the Company's executive compensation programs.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF ITEM 2.

ITEM 3:    ADVISORY VOTE ON FREQUENCY OF FUTURE ADVISORY VOTES ON EXECUTIVE COMPENSATION

        Valmont is asking shareholders to vote on whether future advisory votes on executive compensation, of the nature reflected in Item 2 above, should occur every year, every two years, or every three years. The shareholders will vote on the following resolution:

"RESOLVED, that the Company include in its proxy statement an advisory vote on executive compensation every one year, two years, or three years."

        The board of directors, upon recommendation of the Human Resources Committee, has determined that an advisory vote on executive compensation that occurs every year is the most appropriate alternative for Valmont at this time.

        In formulating its recommendation, the board of directors considered that an annual advisory vote on executive compensation will allow our shareholders to provide their direct input on the Company's compensation philosophy, policies and practices as disclosed in the proxy statement every year. While the Company's executive compensation programs are designed to promote a long-term connection between pay and performance, the board of directors recognizes that executive compensation disclosures are made annually. Given that the say-on-pay advisory vote provisions are new, holding an annual advisory vote on executive compensation provides the Company with more direct and immediate feedback on our compensation disclosures. Shareholders should realize that because the advisory vote on executive compensation occurs well after the beginning of the compensation year, in most cases it may not be feasible to change any executive compensation program in consideration of any one year's advisory vote on executive compensation.

        Shareholders will be able to specify one of four choices with respect to this proposal on the proxy card: one year, two years, three years, or abstain. The option of one year, two years or three years that receives the highest number of votes cast by shareholders will be the shareholder-approved frequency

selection for the advisory vote on executive compensation. The vote is advisory and not binding; however, the Board and the Human Resources Committee will carefully review the voting results. Notwithstanding the Board's recommendation and the outcome of the shareholder vote, the Board in the future may decide to conduct advisory votes on a more or less frequent basis than the option receiving the most votes cast in 2011 by our shareholders.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" EVERY ONE YEAR ON THE FREQUENCY OF THE EXECUTIVE COMPENSATION VOTE.

ITEM 4:    RATIFICATION OF APPOINTMENT OF INDEPENDENT AUDITORS

        The firm of Deloitte & Touche LLP and the member firms of Deloitte Touche Tohmatsu, and their respective affiliates (collectively "Deloitte Entities") conducted the 2010 and 2009 audits of the Company's financial statements. Fees billed by the Deloitte Entities to the Company for services provided during the 2010 and 2009 fiscal years were as follows:

        Audit Fees consist of the audit of the Company's fiscal 2010 and 2009 annual financial statements, review of the Company's quarterly financial statements during 2010 and 2009, fees associated with registration statements and other services that are normally provided in connection with statutory and regulatory filings. Audit fees also included the audit of the effectiveness of the Company's internal control over financial reporting. Audit services have increased due to the statutory audit requirements of the subsidiaries purchased by Valmont as part of the Delta plc acquisition.

        Audit-Related Fees consist of financial statement audits of employee benefit plans, consents related to Securities and Exchange Commission filings, agreed-upon procedures, documentation review in connection with the Company's internal controls over financial reporting and due diligence services performed with respect to acquisitions. Audit-related fees have increased due the acquisition of Delta plc; Deloitte performed due diligence, IFRS to US GAAP assessment and issued consents in connection with the Company's offering of debt securities on Form S-3, which required Deloitte to perform additional audit procedure to comply with United States generally accepted auditing standards.

        Tax Fees consist of international tax planning and federal, state and expatriate tax compliance.

        The Committee pre-approves all audit and permitted non-audit services to be performed by the independent auditor, including audit services, audit-related services, tax services and any other services. The Committee periodically grants pre-approval of specific audit and non-audit services including cost levels for such services. Any services not covered by prior pre-approvals, or services exceeding the pre-approved cost levels, must be approved in advance by the Committee. In periods between Committee meetings, the Committee Chairman has the delegated authority to pre-approve additional services, and such pre-approvals are then communicated to the full Committee.

        The Audit Committee has appointed Deloitte & Touche LLP as independent auditors to conduct the 2011 audit of the Company's financial statements and requests that the shareholders ratify this appointment. A representative from Deloitte & Touche LLP will be present at the annual meeting of shareholders and will have the opportunity to make a statement and to respond to appropriate

questions. In the event the shareholders do not ratify the appointment, the appointment will be reconsidered by the Audit Committee.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" ITEM 4.

Shareholder Proposals

        Shareholder proposals intended to be presented at the next annual meeting of shareholders must be received by the Company no later than November 18, 2011 in order to be considered for inclusion in the proxy statement for such meeting.

        The Company's bylaws set forth certain procedures which shareholders must follow in order to nominate a director or present any other business at an annual shareholders' meeting. Generally, a shareholder must give timely notice to the Secretary of the Company. To be timely, such notice must be received by the Company at its principal executive offices not less than ninety nor more than one hundred twenty days prior to the meeting. The bylaws specify the information which must accompany such shareholder notice. Details of the provision of the bylaws may be obtained by any shareholder from the Secretary of the Company.

Section 16(a) Beneficial Ownership Reporting Compliance

        Section 16(a) of the Securities Exchange Act of 1934 requires executive officers and directors to file reports of changes in ownership of Valmont's common stock with Securities and Exchange Commission. Executive officers and directors are required by SEC regulations to furnish Valmont with copies of all Section 16(a) forms so filed. Based solely on a review of the copies of such forms furnished to Valmont and written representations from Valmont's executive officers and directors, Valmont believes that all persons subject to these reporting requirements filed the required reports on a timely basis during fiscal 2010, except for except for one report for Mr. den Daas, which report was filed late due to administrative error.

Other Matters

        The board of directors does not know of any matter, other than those described above, that may be presented for action at the annual meeting of shareholders. If any other matter or proposal should be presented and should properly come before the meeting for action, the persons named in the accompanying proxy will vote upon such matter and upon such proposal in accordance with their best judgment.
