    We are distributing our proxy materials to our shareholders primarily 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 11, 2026, 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.
    We will provide a live audio webcast of the meeting beginning at 10:00 a.m. Central Daylight Time on April 27, 2026. The webcast will provide the audio portion of the meeting only. The webcast does not constitute attendance, but will provide shareholders who cannot attend an opportunity to receive timely audio of the meeting.
    To listen to the meeting by telephone, please dial 1-877-407-6184 or 1-201-389-0877 (no Conference ID is needed), or point your browser to investors.valmont.com.
    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 and the 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.
    We look forward to seeing you at our Annual Meeting.

    2026 Proxy Statement 1

    ​
     
    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 Monday, April 27, 2026, or at any adjournments thereof.
    At the close of business on March 2, 2026, the record date for shareholders entitled to notice of and to vote at the meeting, there were outstanding 19,547,213 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.
    We will provide a live audio webcast of the meeting beginning at 10:00 a.m. Central Daylight Time on April 27, 2026. The webcast will provide the audio portion of the meeting only. The webcast does not constitute attendance, but will provide shareholders who cannot attend an opportunity to receive timely audio of the meeting. To listen to the meeting by telephone, please dial 1-877-407-6184 or 1-201-389-0877 (no Conference ID is needed), or go to investors.valmont.com, where a link will provide for access to the audio of the meeting.
    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 not 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 four 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 or her resignation to the board, and the resignation will be accepted or rejected by the board as more fully described in Election of Directors.
    The proposals to approve the ratification of the appointment of the auditors, approve the Valmont 2026 Employee Stock Purchase Plan and the 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.
    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., 15000 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 11:59 p.m. Eastern Time on April 26, 2026. 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 shareholders electronically via the Internet. On March 11, 2026, 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 1-800-579-1639 or by email at [email protected].
    The cost of solicitation of proxies, including the cost of reimbursing banks and brokers for forwarding proxy materials to their principals, will be borne by the Company.

    2026 Proxy Statement 3

    ​
    Item 1: Board of Directors and Election of Directors
    The Company’s board of directors is currently composed of eleven 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 Annual Meeting: Directors Bay, Favre and Lanoha. These individuals, plus new director Paul Maass have been nominated by the board of directors, upon recommendation of the Governance and Nominating Committee, for re-election to three-year terms.
    Seven directors have joined the board since June 2015. Three directors who were identified by an independent third-party search firm joined the board since 2020.
    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 an incumbent director receives a greater number of votes “withheld” than “for”, the director is required to promptly tender his or her 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 or her 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 the director would be over age 75 at the time of election. The board evaluated Mr. Bay’s experience and value in director leadership and strategic planning matters and determined not to apply the policy to Mr. Bay.
    The board has nominated Mr. Bay for a three-year term expiring in 2029. Mr. Bay will continue to serve as Chair of the Board until April 2027. Ms. Paglia, current lead director, will become Vice Chair of the Board in April 2026 and Chair of the Board in April 2027 (and Valmont will no longer have a lead director).
    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 four nominees, and the seven directors whose terms expire in 2027 and 2028, 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.

    Procedures for bringing concerns or complaints to the attention of the Audit Committee
    ​
    The board met five times during 2025. 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 2025 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 in 2025 consisted of a Non-Executive Chairman and a Lead Director. Mr. Bay became Non-Executive Chairman in 2019. 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. Mr. Bay will continue to serve as Chair of the Board until April 2027. Ms. Paglia, current Lead Director, will become Vice Chair of the Board in April 2026 and Chair of the Board in April 2027 (and Valmont will no longer have a lead director).
    The board has established the position of Lead Director. The position is currently filled by independent director Catherine James Paglia. The lead director presides at executive sessions of the independent directors, approves director meeting agendas, has the ability to call meetings of the independent directors, reviews the membership of board committees, and serves as a liaison between the independent directors and the Chief Executive Officer. 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., 15000 Valmont Plaza, Suite 202, Omaha, Nebraska 68154.
    The board has oversight responsibility for risks affecting the Company. The board has delegated risk oversight with respect to operational, compliance and financial matters including legal, insurance, information technology and cybersecurity risk to the Audit Committee. The board has delegated risk oversight with respect to human capital resources and compensation matters and labor practices, human rights policies, employee health and safety, and employee diversity and inclusion to the Human Resources Committee. The board has delegated risk oversight with respect to governance structure related matters and shareholder engagement, and board leadership, succession, onboarding and education to the Governance and Nominating Committee. The board has delegated risk oversight of policies and operational controls of environmental, health and safety, and social risks, and oversight of sustainability matters, including climate change, energy management, water standards and carbon management, to the Governance and Nominating Committee.
    GOVERNANCE ACTIONS
    The board of directors and board committees have taken a number of 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.
    ​
    2026 Proxy Statement 15

    ​
    Corporate Governance
    ■
    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 stock ownership and retention guidelines for senior management. The guidelines require an equity position having a value of 6.0 times base salary for the Chief Executive Officer, 2.5 times base salary for the Chief Financial Officer, Executive Vice Presidents, and Group Presidents, 1.5 times base salary for Senior Vice Presidents, and 1.0 times base salary for other corporate officers. The officers are required to retain 50% of the net shares acquired upon the exercise of stock options and the vesting of restricted stock until the stock ownership guidelines have been attained and maintained. The Company also has a policy prohibiting stock hedging and stock pledges applicable to directors and officers.
    ​
    ■
    The board of directors has adopted a written clawback policy pursuant to SEC and NYSE rules applicable to executive officers. The policy provides for the recovery of incentive based compensation awarded to current and former executive officers that is received in a three-year period preceding a restatement of the Company’s financial statements due to material noncompliance with any financial reporting requirement under securities laws.
    ​
    ■
    The board of directors has adopted a broader compensation recoupment policy applicable to any employee who receives incentive awards. The policy generally provides that if Valmont is required to restate its financial statements, due to material noncompliance with any financial reporting requirements, the board of directors may require reimbursement of all or any part of any cash or stock award 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 recoupment 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 FW Cook as its independent executive compensation consulting firm. The Company does not engage FW Cook for any services beyond their support of the Human Resources Committee.
    ​
    ■
    The board of directors has adopted an insider trading policy. A copy is filed with the 2024 Form 10-K. The policy prohibits directors, officers and employees from trading in Company securities when in possession of material nonpublic information and requires Company insiders to trade during quarterly trading window periods and to pre-clear transactions. As provided in the policy, from time to time, Valmont may engage in transactions in its own securities. Valmont’s policy is to comply with all applicable securities and state laws (including appropriate approvals by the Valmont Board of Directors) when engaging in transactions in Valmont securities. Valmont purchases its securities pursuant to the board-authorized share repurchase program either during quarterly trading windows established for Valmont insiders or pursuant to written trading plans complying with SEC Rule 10b5-1.
    ​
    ■
    The Human Resources Committee generally grants equity awards at regularly scheduled meetings in February (for performance share units) and December (for stock options and restricted stock units) of each year and does not time the granting of equity awards to the disclosure of material nonpublic information or to the fluctuation in the market value of the Company’s common stock.
    ​
    ■
    The Company does not have a Shareholder Rights Plan.
    ​
    BOARD INDEPENDENCE
    The board of directors is composed of a substantial 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.
    ​
    ■
    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
    ​
    16 2026 Proxy Statement

    ​
    Corporate Governance
    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.
    ■
    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.
    ​
    ■
    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.
    ​
    The board has determined that all directors except Mr. Applbaum (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 purchases from a subsidiary of Peter Kiewit Sons’ Inc. (a construction company with in excess of $18 billion revenue) were in the ordinary course of business and immaterial.
    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. In 2020, the Committee retained the services of an independent director search firm which resulted in the addition of Joan Robinson-Berry and Ritu Favre to the Board in 2020 and Deborah Caplan in 2024. In 2026 Paul T. Maass was added to the board following recommendation by a non-management director.
    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 gender, race and national origin.
    ​
    ■
    Both domestic and international business experience, which should reflect a broad experience at the policy-making level in business, government or education.
    ​
    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, by telephone, video or in person. 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 evaluation.

    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 these sections of the proxy statement: (1) the summary compensation table and related tables, (2) the Committee information in the corporate governance section and (3) the compensation summary in the advisory vote on executive compensation section.
    SAY-ON-PAY VOTE
    Valmont conducted its first advisory vote on executive compensation in April 2011. The compensation resolution has passed with at least 95% of the vote in each year, including 96.3% in 2025. Valmont’s shareholders in April 2023 cast 97.0% of their votes in favor of an annual frequency say-on-pay vote. The board of directors and the Committee considered these results in determining compensation policies and decisions, and determined to hold annual say-on-pay votes and, based on the significant level of shareholder support, to continue the current compensation objectives, strategies, processes and practices described below.
    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:
    ​ ​
    ​ ​
    ■
    Provide target total compensation levels at competitive market rates to attract, retain, motivate and reward the performance of executive officers and other key employees;
    ​
    ​ ​
    ​ ​
    ■
    Direct management focus to (1) the long-term growth of the Company, (2) enhance shareholder value, and (3) ensure that executive officers have significant equity ownership without increasing dilution over acceptable levels; and
    ​
    ​ ​
    ​ ​
    ■
    Pay for performance by providing performance-based incentive plans measured against pre-established targets, with no guaranteed minimum payment provisions, and with actual payments above median market levels for exceeding performance targets and below median market levels if performance targets are not achieved.
    ​
    ​ ​
    [MISSING IMAGE: ic_downarrow-pn.jpg] [MISSING IMAGE: ic_downarrow-pn.jpg] [MISSING IMAGE: ic_downarrow-pn.jpg] [MISSING IMAGE: ic_downarrow-pn.jpg]
    ​ ​
    The Committee established compensation strategies designed to carry out the compensation objectives, including:
    ​ ​
    ​ ​
    ■
    Target total compensation evaluated by position, on an annual basis, against like positions in companies of similar sales volume, according to data provided by the Committee’s independent compensation consultant; and
    ​
    ​ ​
    ​ ​
    ■
    Base pay, annual incentives and long-term incentives targeted at market median levels, such that actual compensation will be above median if performance exceeds targets and below median when performance is below targets.
    ​
    ​ ​
    The Committee has engaged FW Cook as the Committee’s independent executive compensation consultant. FW Cook reports directly to the Committee and provides advice to the Committee on the structure and amounts of executive and non-employee director compensation. FW 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 target total compensation are reviewed annually against general industry survey data and a peer group developed by FW Cook and approved by the Committee. The Committee uses the survey data and peer group information to assess the competitiveness of target compensation levels and pay mix for the CEO, CFO and other executives.
    ​
    18 2026 Proxy Statement

    ​
    Compensation Discussion and Analysis
    ■
    The Company has used as its primary benchmark surveys based on market data provided by FW Cook adjusted to provide market compensation levels for companies within a range of Valmont’s annual revenues. For 2025 compensation established in December 2024 (for 2025 base salaries) and February 2025 (for 2025 incentive plans), the Committee used a national general industry survey of approximately 500 companies. The survey data was size adjusted to Valmont’s 2024 revenues of approximately $4.1 billion. The competitive medians referenced below for base salary, target annual incentives and target long-term incentives are the competitive medians based on the survey data.
    ​
    ■
    For 2026 compensation established by the Committee in December 2025 (for 2026 base salaries) and February 2026 (for 2026 incentive plans), the Committee again used a national general industry survey provided by FW Cook of approximately 500 companies. Similarly, the survey data was size adjusted to Valmont’s 2025 revenues of approximately $4.1 billion.
    ​
    ■
    The Committee also used a peer group developed by FW Cook as a supplemental benchmark of CEO and CFO target pay levels. FW Cook advised that, due to differences in the jobs of 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 2025 compensation consisted of the following seventeen companies:

    ■
    The Committee, on FW Cook’s recommendation, revised the peer group in October 2025 (for purposes of the 2026 compensation program) (i) by removing Barnes Group, which was acquired in 2025, and removing Comfort Systems, Hubbell and Xylem, due to their being significantly larger sized with outsized market capitalization and (ii) adding Atkore, AZZ and Timken, due to comparable financial metrics, global operations and business fit. The Company’s peer group consists of sixteen companies following this change.
    ​
    ■
    The Company’s revenues ($4.1 billion for 2025) approximated the median of the new peer group ($4.1 billion).
    ​
    ■
    The Committee also reviews a tally sheet with respect to the total compensation (target and actual) of each named executive officer and each group president. The Committee utilizes tally sheets as a reference point 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 FW Cook as one of the primary factors 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 for the 2023-2025 and subsequent long-term plans consisted of Company performance share units (“PSUs”) payable in Valmont stock. Stock options and restricted stock units (“RSUs”) 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 equity or short-term and long-term incentive compensation and uses the market data provided by FW Cook to inform the appropriate level of each compensation program element. The Committee believes that a majority of an executive’s overall compensation opportunity should be incentive-based.
    ​
    ■
    The structure of all incentive compensation plans is reviewed periodically to assure their linkage to the current strategies, objectives and performance goals.
    ​
    ■
    The Committee’s policy is to establish base salary, target annual incentives and long-term incentive grant values with targets at or near the competitive median level and potential payouts of incentives up to 200% of target when performance significantly exceeds targets. The annual incentive and long-term incentive targets are established for each executive officer by using a percentage of base salary that is generally aligned with the competitive market median for the executive. There are no material differences in compensation policies with respect to individual executive officers.
    ​
    ■
    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 plans, amounts subject to future vesting, and amounts related to stock awards which are subject to special accounting and tax provisions. Section 162(m) of the Internal Revenue Code generally places a $1 million limit on the amount of compensation a company can deduct in any one year for certain officers. Consequently, compensation paid to certain officers in excess of $1 million may not be deductible.
    ​
    2026 Proxy Statement 19

    ​
    Compensation Discussion and Analysis
    ELEMENTS OF COMPENSATION.
    Valmont’s executive compensation is based on three components, each of which is intended to support the overall compensation philosophy.
    ■
    The three components are base salary, annual performance incentives, and long-term performance incentives (which consist of equity incentives). For 2025, base salary accounted for approximately 22.3% of the total target annualized compensation of the ongoing named executive officers and incentive compensation accounted for approximately 77.7% of such total compensation.
    ​
    ■
    Valmont’s executive officers do not have employment agreements.
    ​
    ■
    Valmont’s 2022 Stock Plan provides for accelerated vesting of non-vested amounts in the event of an involuntary termination following 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 limited use of Company aircraft for personal travel are included in the summary compensation table.
    ​
    ■
    Valmont has an executive compensation recoupment policy covering cash and equity described on page 12. The policy is broader than the SEC-required Policy for the Recovery of Erroneously Awarded Compensation.
    ​
    ■
    Valmont has policies prohibiting hedging and pledging of Company stock by directors and officers.
    ​
    2025 COMPENSATION PROGRAM ELEMENTS
    BASE SALARY
    Base salary is targeted at the competitive median level. Competitive median levels for 2025 were provided by FW Cook based on national general survey data which was the primary market reference point. 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 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 salary plan is modified as deemed appropriate and approved by the Committee. The Committee reviews and establishes the base salary of the Chief Executive Officer based on competitive compensation data provided by FW Cook using data for similar sized companies 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 expectation as to his future contribution in directing the long-term success of the Company and its businesses.
    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 Company’s contributions to such plans for 2025 compensation (4.5% of covered 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 in December 2024 reviewed the base salaries of executive officers for 2025. The base salaries for Messrs. Applbaum, Liguori, Donahue and Matthews were each increased 3.5% to $1,052,000, $672,750, $642,735 and $543,375, respectively. In connection with their promotions within the Infrastructure segment in April 2025, Mr. Colwell’s annual base salary was increased 4.6% to $580,000 and Mr. Turi’s annual salary was increased 10.4% to $480,000, prorated from the date of their promotions.
    The Committee reviewed executive base salaries for 2026 in December 2025 based on the same factors described above. The base salary for Mr. Applbaum was increased 6% and the base salary for Mr. Liguori was increased 5%. The base salaries for Messrs. Colwell, Matthews and Turi were each increased 3.5%.
    ANNUAL INCENTIVES
    The Company’s short-term incentives for 2025 were established by the Committee. The Committee determined annual incentives for 2025 for corporate-level participants, which include the named executive officers, were based 75% on net earnings improvement and 25% on revenue growth. Annual incentives are targeted at the competitive median level as provided by FW Cook. For 2025, each named executive officer’s annual incentive opportunity ranged from 0% to 200% of the target, depending on the level of achievement of the Company’s performance goals.

    Compensation Discussion and Analysis
    For named executive officers’ 2025 annual incentives, a target incentive was established ranging from 60% to 115% of base salary, and performance goals were set based on net earnings and revenue growth results.

    A minimum threshold level of performance 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. Participants, thresholds and specific performance levels are established by the Committee at the beginning of each fiscal year. The Committee may also award discretionary non-incentive-based bonuses to an executive officer to recognize exceptional performance in a particular year. No discretionary awards were made to named executive officers with respect to performance in the last three years.
    The Committee approved in February 2025 participation, including executive officers, in the short-term incentive program for 2025. Each performance measure operates independently. The Committee established the measures below to be used for the incentive threshold (payout at 50% of target), target incentive (payout at target), and maximum incentive (payout at 200% of target) for both 2025 net earnings improvement and 2025 revenue growth. Payouts are linearly interpolated for performance between threshold/target and target/maximum performance levels. There is no payout for each metric for performance below threshold.

    The threshold, target and maximum amounts for revenue growth represent total revenue numbers. The 2025 net earnings were adjusted. The adjusted net earnings were $371.5 million (GAAP net earnings of $350.3 million, increased by (i) $91.4 million of long-lived asset impairments, (ii) $16.1 million of realignment expense, (iii) $3.9 million of other non-recurring charges and decreased by (i) $10.9 million license asset write-off, (ii) $0.8 million of tax effect of the adjustments and (iii) $78.5 million non-recurring tax benefits, which resulted in net earnings performance at 103.5% of target. The 2025 revenue was $4,104.1 million which resulted in performance at 67.5% of target. The combination of the two factors resulted in an annual incentive payout for the named executive officers at 94.5% of target for 2025.

    LONG-TERM PERFORMANCE INCENTIVES
    Long-term performance incentives for senior management in 2025 were provided in two ways: through the long-term performance share program, and through equity awards, each granted under the shareholder approved 2022 Stock Plan. Both long-term performance incentive programs (long-term performance share plan and equity awards) are targeted at competitive median levels. Competitive median levels are provided by FW Cook. For the three-year award cycle ended in 2025, each named executive officer’s long-term incentive opportunity under the performance share program ranged from 0% to 200% of the targeted incentive, depending on the level of achievement of the Company’s performance goals.
    The current long-term performance share programs operate on three-year award cycles. The Committee selects participants, establishes target awards, and determines a performance matrix. The Committee in February 2023 approved the performance matrixes for the award cycle ending in 2025 to encourage both the effective use of the Company’s capital and the growth of its earnings, and consequently the matrix was based on average return on invested capital or “ROIC” and cumulative compound operating income growth or “OIG”, weighted 70% ROIC and 30% OIG, at the beginning of the award cycle. Each performance measure operates independently. The Committee established the following performance measures for ROIC and OIG for the award cycle ending in 2025:

    Compensation Discussion and Analysis
    The Committee in February 2023 selected the participants, including the named executive officers, for participation in the three-year award cycle ending in 2025. Targets for the 2023-2025 award cycle for the named executive officers were established based on a predetermined percentage ranging from 40% to 200.0% of base salary, which amount was converted to PSUs valued at the Company’s stock price at the beginning of the performance period (which for the 2023-2025 performance period was a thirty-day average of $332.59). The percentage of base salary for the named executive officers was:

    ​
    The performance matrix provides for the potential payouts to be increased or decreased in number based on greater or lesser levels of performance. Earned PSUs are issued at the end of the performance period, the value of 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 one year after grant, or a change in control. Earned PSUs are capped at two times the target number of PSUs. The Committee approves the number of PSUs to be paid following a review of results at the end of each performance cycle. Awards are paid in shares of common stock.
    Based on the above described ROIC and OIG performance goals established by the Committee, the Company’s three-year average ROIC on an adjusted basis was 14.60% and the three-year cumulative compound adjusted operating income growth was 2.30%, resulting in PSUs earned for the 2023-2025 period at 102.9% of target. The Company’s calculation of return on invested capital for the three years on an adjusted basis is on page 38. The 2023 adjusted operating income (GAAP operating income of $291 million increased by (i) $176 million pre-tax impairment of long-lived assets and organizational realignment expenses, (ii) $5.4 million of other pre-tax non-recurring expenses and (iii) $10.9 million Prospera pre-tax intangible asset amortization and Prospera share compensation) was $483.3 million. There were no adjustments to 2024 operating income. The 2025 adjusted operating income (GAAP operating income of $415.6 million) decreased by $100.09 million tax benefit, consisting of a GAAP tax rate effect of $26.3 million and worthless securities deduction of $73.8 million, was $315.5 million.
    The Company’s stock price during the performance period increased from a start date 30 day average of $332.59 to $412.20 which increased the value of the earned PSUs. The 2023-2025 long-term incentives were paid in Company common stock. Long-term plan shares were earned by the named executive officers as follows:

    Mr. Donahue participated in the 2024-2026 and 2025-2027 long-term incentive plans until December 27, 2025 and received on a prorated basis 3,335 shares under the plans based on the projected level of achievement as determined by the Committee in February 2026.
    In February 2025, the Committee selected the participants and established the performance goals for the 2025-2027 award cycle; the performance goals for the cycle ending in 2027 are again based on a combination of growth in operating income and return on invested capital weighted 70% to ROIC and 30% to OIG, with each metric independently weighted. Targets were established for named executive officers based on a percentage of base salary ranging from 40% to 237.5% and performance targets established at 17.0% average ROIC and 5% OIG growth. Any 2025-2027 long term incentive award will be paid in shares of common stock.
    STOCK INCENTIVES AND OWNERSHIP GUIDELINES
    The board of directors, upon recommendation of the Committee, has established stock ownership and retention guidelines for senior management. The guidelines require an equity position (shares owned and restricted share units held) having a value of 6.0 times base salary for the Chief Executive Officer, 2.5 times base salary for the Chief Financial Officer, Executive Vice Presidents and Group Presidents, 1.5 times base salary for senior vice presidents and 1.0 times base salary for other corporate officers. The officers are required to retain 50% of the net shares acquired upon the exercise of stock options and the vesting of restricted stock until the stock ownership guidelines have been attained and maintained. All ongoing named executive officers currently meet the targets using the closing stock price on the March 2, 2026 record date with the exception of Mr. Liguori and Mr. Matthews each of whom joined the Company in 2024.
    Long-term stock incentives are provided through grants of stock options and RSUs to executive officers and other key employees pursuant to the shareholder approved 2018 Stock Plan and 2022 Stock Plan. 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 2023, 2024 and 2025 made at the regularly scheduled Committee meeting in December of each year as part of the compensation for the upcoming year. Stock options are exercisable at the market value on the date of grant and have value only if the Company’s stock price increases. Stock options granted during 2025 vest beginning on the first anniversary of the grant in equal amounts over three years and expire ten 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 involuntary termination following a change-of-control. If an employee retires after age 55 (with five years of service) and age and service adds up to 70 along with a 6 month notice, options continue to vest and be exercisable according to the original terms. The Company’s stock plans prohibit repricing. RSUs vest in no less than three equal installments beginning on the first anniversary of the grant; the units also vest on death, disability and involuntary termination following a change-of-control, and vesting is prorated for job elimination and continue to vest in full if the one year service requirement has been met if an employee retires after age 55 (with five years of service) and age and service adds up to 70 along with a 6 month notice.
    The Committee establishes the number and terms of the options and RSUs granted under the stock plans. The Committee established the terms and provisions of such equity grants based on industry standards as provided to the Committee by its independent compensation consultant. The Committee established the number of options and RSUs 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 based on the Company’s estimate of the options’ fair value at the time of grant, using the valuation assumptions described in the following sentence. The fair value of the options granted are reflected in the Summary Compensation Table as computed with subsequently refined assumptions in accordance with FASB Accounting Standards Codification Topic 718, which is described in footnote 11 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 2, 2026.

    Compensation Discussion and Analysis
    Outstanding performance by an individual executive officer is recognized through larger equity grants. The Committee, in determining grants of equity under the stock plans, also reviews and considers the executive’s history of retaining shares previously obtained through the exercise of prior options and restricted stock grants. In December 2025, stock options and/or RSUs were granted to named executive officers with a fair market value of a percentage of base salary as follows:

    The amounts were established so that aggregate long-term incentive compensation would be targeted at competitive median levels. Competitive median levels are provided by FW Cook based on the primary benchmark national general industry survey data.
    The Committee granted options for an aggregate of 22,216 shares and 36,249 RSUs, for an aggregate of 58,465 shares, to a total of 359 employees in December 2025, including options and RSUs to named executive officers as described below. The Committee granted 5,211 RSUs to directors in April 2025.
    The Committee determined that the annual equity grants to the executive officers should be 50% stock options and 50% RSUs (on a value basis), to reflect current market practices as determined by FW Cook. In December 2025, the Committee granted the following stock options and RSUs to the named executive officers:

    ​ ​ ​ ​ 1,205 ​ ​ ​ ​ ​ 391 ​ ​
    The option grants and restricted stock unit grants vest in equal installments over three years; the options have a ten-year term. 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. Mr. Donahue entered into a separation agreement in 2025 and did not receive option grants or RSUs.
    The Committee believes 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 will continue to monitor the relationship among executive compensation, the Company’s performance, and shareholder value.
    EXECUTIVE OFFICER CHANGE PAYMENTS
    On May 14, 2025, Valmont entered into a separation agreement with Mr. Donahue specifying the terms of his separation, and the orderly transition of his duties and responsibilities. As previously reported, Mr. Donahue’s executive position was eliminated on April 29, 2025 and he transitioned to a non-executive advisor role with Valmont. Pursuant to the agreement, Mr. Donahue remained in the employ of Valmont until December 27, 2025. He agreed to confidentiality, cooperation and restrictive covenants as provided in the agreement. In consideration of the foregoing he continued to receive his base salary and health benefits until the end of his employment. Subject to conditions in the agreement, he received (i) cash severance according to Valmont’s general severance policy, equal to 20 weeks of his base salary plus one week for each year of his service (7 weeks), (ii) his previously awarded RSUs and stock options continued on the grant date terms to vest while he was employed (until December 27, 2025), and (iii) he continued to participate at his previously granted performance award levels on the grant date terms in Valmont’s 2025 short-term incentive plan and on a prorated basis (to December 27, 2025) in the 2023-2025, 2024-2026 and 2025‑2027 long-term incentive plans. His RSUs, stock options and PSUs that were not vested by December 27, 2025 were forfeited.

    Compensation Discussion and Analysis
    HEDGING AND PLEDGING POLICY
    Valmont’s policy prohibiting directors and officers from hedging or pledging Company stock has been in effect for more than ten years. The current policy prohibits hedging and pledging transactions by directors, executive officers, corporate officers and group presidents with respect to any Valmont equity securities held directly or indirectly by such persons. Hedges are any transactions designed to hedge or offset any decrease in the market value of Valmont equity securities. Such transactions include short-sales, prepaid variable forward contracts, equity swaps, collars, and exchanges.
    COMPENSATION RISK ASSESSMENT
    The Human Resources Committee in February 2026 conducted a risk assessment of the Company’s compensation programs which was reviewed by its independent compensation consultant. The Committee determined that the risks arising from the Company’s compensation policies and practices are not reasonably likely to have a material adverse effect on the Company. 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 and segment 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 PSUs, stock options and RSUs, have a three-year performance period or vesting period and consequently the value to executives varies with the Company’s stock price over the period. The Company has a stock retention policy which requires retention of 50% of the net shares acquired upon the exercise of stock options and the vesting of restricted stock until stock ownership guidelines are met. The Committee does not take material nonpublic information into account when determining the timing and terms of equity awards and has not timed the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation. The Company has an executive clawback policy for the recovery of erroneously awarded incentive compensation following a financial restatement due to material noncompliance with financial reporting requirements. The Company has a broader compensation recoupment policy applicable to employees in the event of financial restatements due to fraud. The Company also has policies which prohibit the hedging or pledging of Company stock by directors and officers.

    Pay Ratio Information
    We are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of our Chief Executive Officer (CEO) for our fiscal year 2025. The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with applicable securities regulations.
    For our fiscal year ended December 27, 2025:
    ■
    The median of the annual total compensation of all employees of our company (other than our CEO) was $63,697.
    ​
    ■
    The annual total compensation of our CEO as reported in the Summary Compensation Table was $7,762,266.
    ​
    ■
    Based on this information, for 2025 the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all employees was 121.9 to 1.
    ​
    To identify the median of the annual total compensation of all our employees, we selected September 30, 2025 as the date for data gathering to identify the median employee because it enabled us to make such determination in a reasonably efficient and economical manner. We used the total cash compensation (base salary, cash bonuses and cash incentives) of all employees globally as reflected in payroll records. We identified our median employee using this compensation measure, which was consistently applied to all our employees included in the calculation.
    We did not use the same median employee as we did in 2024, since we are required to use a new median employee at least every three years pursuant to SEC rules.
    Once we identified our median employee, we combined all elements of such employee’s compensation for 2025 to arrive at such employee’s total compensation in the same manner as we arrived at our CEO’s total compensation as set forth in the Summary Compensation Table.

Company contributions match executive contributions to the 401(k) and related nonqualified deferred compensation plans with respect to compensation and are included in the Summary Compensation Table under All Other Compensation. Company contributions are 4.5% of the executive officer’s salary, bonus and cash incentives.

    The Company does not have a pension plan or other defined benefit plan. The Company’s nonqualified deferred compensation plan is offered to allow certain Company employees who, due to compensation and contribution ceilings established under the Internal Revenue Service regulations, are limited in making contributions to the Company’s 401(k) plan. This plan is fully funded and the related assets in the plan are reported on the Company’s balance sheet and are subject to creditor claims in event of the Company’s bankruptcy. The vesting provisions follow that of the Company’s 401(k) plan. Compensation that is eligible for deferral by the executive includes salary, bonus and cash incentives, and the executive may defer any percentage of eligible compensation. Investment values and related earnings are based on quoted market prices of the investments held by the plan. Investment alternatives under the plan are selected by each employee and may be changed based on the rules set forth by each investment fund selected by the employee. Distribution payments are made upon a specified period after separation from service in accordance with Section 409A of the Internal Revenue Code. The methods of distribution include single lump sum cash payment or annual installments for 2-10 years. In-service withdrawals are allowed in compliance with Section 409A of the Code.

    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. During 2025 in connection with his departure, Valmont entered into a separation agreement and release with Mr. Donahue. See Compensation Discussion and Analysis — Executive Officer Change Payments.
    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 16 weeks of salary plus one week of salary for each year of service. 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 2018 Stock Plan and 2022 Stock Plan provide that all outstanding options become immediately exercisable in the event of an involuntary termination following a change-in-control and that all restrictions on restricted stock lapse in the event of such an involuntary termination following 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. If such a change-in-control (involving an involuntary termination) or retirement had occurred on the last day of fiscal 2025, the incremental value (fair market value of company common stock on such date less exercise price) of unvested options and unvested restricted stock and RSUs held by the named executed officers would have been:

    Item 2: Approval of Employee Stock Purchase Plan
    The board adopted the Valmont 2026 Employee Stock Purchase Plan (the “ESPP”) on February 23, 2026, subject to shareholder approval. The ESPP is not intended to qualify for special tax treatment under Section 423 of the Internal Revenue Code. The ESPP is designed to encourage and enable our eligible employees to acquire a proprietary interest in Valmont through the ownership of our common stock, which is intended to enhance their sense of participation in Valmont’s performance and provide an incentive for them to continue employment.
    The ESPP will allow employees to accumulate payroll deductions over designated purchase periods, which are then used to purchase shares of Valmont common stock at fair market value on designated purchase dates. Valmont will provide plan participants with a matching grant of one share for each three shares purchased by the participant on the applicable purchase date. A total of 200,000 shares of common stock, or approximately one percent of our outstanding shares as of March 2, 2026, may be purchased or otherwise issued under the ESPP. We believe the shares reserved under the Plan will be sufficient for purchases and grants under the Plan for five to seven years.
    The following is a summary of the material terms of the ESPP. This summary is qualified in its entirety by reference to the ESPP document, a copy of which is attached as an appendix to the electronic copy of this proxy statement filed with the SEC and may be accessed from the SEC’s home page (www.sec.gov) or on our website at www. https://investors.valmont.com where it is an appendix to the electronic copy of this proxy statement. We will provide shareholders a copy of the ESPP without charge upon request by email to [email protected].
    Administration
    The ESPP is administered by the Human Resources Committee (the “Committee”). All questions of interpretation regarding the ESPP are determined by the Committee. The plan is generally administered by a plan committee (the “Plan Committee”) of the employees appointed by the Committee. The Plan Committee may appoint one or more agents as it deems necessary or appropriate to assist with the day-to-day operation and general administration of the ESPP. The Plan Committee may also adopt such rules, guidelines and forms as it deems appropriate to administratively implement the ESPP.
    Eligibility; Participation; Contribution Limits
    Generally, employees of Valmont and its participating subsidiaries (the “Participating Employer”) in any country or jurisdiction in which Valmont or a Participating Employer conducts business are eligible to participate in the Plan. On December 27, 2025, Valmont’s fiscal year end, the company employed 6,294 individuals in the U.S. and 4,497 individuals internationally. Employees who are subject to the reporting requirements of Section 16(a) of the Securities Exchange Act of 1934, as amended, and employees identified by the Committee in writing are not eligible to participate in the plan.
    The Committee may require an employee to have a minimum service qualification. The plan will be offered only in those countries, jurisdictions and/or to entities that the Committee designates, in its sole discretion, prior to the start of a purchase period. The Committee may limit, suspend, condition or exclude participation in any country or jurisdiction at any time to address legal, tax, securities-law, exchange-control or administrative considerations (including through the adoption of country schedules or sub-plans).
    An eligible employee may begin participating in the ESPP by executing a payroll deduction election form. Once enrolled in the ESPP, a participant is able to purchase shares of our common stock with payroll deductions on the applicable purchase date. Once a purchase period is over, a participant is automatically enrolled in the next purchase period unless the participant chooses to withdraw from the ESPP, the participant’s employment is terminated, or the participant contributes an amount equal to or in excess of $3,000, which is the maximum contribution amount permitted under the ESPP in a calendar year.
    The length of the initial accumulation periods under the Plan is six months commencing on (i) December 1 and ending on May 31 and (ii) June 1 and ending on November 30, provided that the Committee may revise the start, end and length of the purchase periods at any time.
    Shares Subject to the ESPP
    A total of 200,000 shares of Valmont common stock may be issued under the ESPP, which includes all shares issued in the plan, including the shares purchased by participants and issuance of shares as a matching grant. As of March 2, 2026, a total of 19,547,213 shares of Valmont common stock were outstanding. Shares issued under the ESPP may consist, in whole or in part, of previously unissued shares, treasury shares or shares purchased on the open market. As of March 2, 2026, the closing price per share of Valmont common stock as reported on the NYSE was $458.91.
    The number of shares available under the plan is subject to adjustment in the event of stock dividend, stock split, recapitalization, merger, consolidation, combination, spin-off, distribution of assets to shareholder, exchange of shares, or other similar corporate transaction or event
    2026 Proxy Statement 41

    ​
    Item 2: Approval of Employee Stock Purchase Plan
    that causes the per-share value of the shares to change, the Committee will make such aggregate adjustments to the plan and matching awards as it deems necessary, in its sole discretion, to prevent dilution or enlargement of rights immediately resulting from such transaction.
    Payroll Deductions; Purchase of Shares; Matching Grant
    Payroll deductions will be made at the participant’s election as a percentage of the participant’s covered compensation in 1% increments up to 10%. The Committee may, in its discretion, establish a minimum contribution amount per accumulation period. In addition, the maximum amount that a participant may contribute to the ESPP for share purchases is limited to $3,000 per calendar year. Payroll contributions may not be increased or decreased (other than decreased to 0%), during a purchase period; however, a participant may withdraw from the ESPP as described below.
    Unless otherwise determined by the Committee, the initial purchase dates under the ESPP will be the first trading date following the purchase period. On each purchase date, Valmont will apply the funds then credited to each participant’s plan account to the purchase of shares of common stock by dividing the amount of funds in the participant’s plan account by the purchase price. The purchase price will be the closing price per share of common stock on the trading date immediately preceding the purchase date. Any resulting fractional share will be notationally allocated to the participant.
    As soon as practicable following the end of each purchase period, the number of shares purchased by each participant will be deposited into an account established in the participant’s name.
    On each purchase date, Valmont will also make a matching grant at a ratio of one share for each three shares purchased on behalf of the participant on the applicable purchase date. If the matching grant results in a fraction of a share, the fraction will instead be awarded as a fractional share contribution notationally allocated to the participant, to be aggregated with other notional fractional shares for the employee on future purchase dates.
    Withdrawal from the ESPP; Termination of Employment
    Upon a participant’s withdrawal from participation from the ESPP, all remaining accumulated payroll deductions in the participant’s plan account will be returned, without interest, to the participant. The participant will be permitted to resume contributions for a future purchase period if he or she then is an eligible employee and completes a new payroll deduction election.
    A participant will cease to participate in the ESPP when the participant ceases to qualify as an eligible employee. Unless otherwise determined by the Plan Committee, all remaining payroll deductions credited to the former participant’s plan account as of such date will be returned, without interest, to the former participant or to the former participant’s designated beneficiary, as the case may be.
    Transferability
    Rights to purchase shares of common stock under the ESPP may not be transferred by a participant and may be exercised during a participant’s lifetime only by the participant.
    Amendment or Termination of the ESPP
    The ESPP will continue until terminated by the board. The board may at any time suspend or discontinue the ESPP. The board or the Committee may, at any time and from time to time, without the consent of participants, amend the ESPP in whole or in part, which as appropriate, may include sub-plans, including to provide flexibility, if necessary, for non-U.S. employee participation. Any amendment which would increase (a) the number of shares authorized under the plan, aside from the permitted adjustments described above, (b) the match ratio or (c) the $3,000 purchase limit, must be submitted for shareholder approval.
    Tax Withholding
    Valmont has the right to withhold from amounts otherwise payable to a participant such withholding taxes as may be required by federal, state, local or other law, or to otherwise require the participant to pay such withholding taxes.
    Federal Income Tax Information
    The income tax consequences under the ESPP to participating employees will vary, based on their country of employment. The following summary briefly describes the U.S. federal income tax consequences of participation in the ESPP. The summary, however, is not a detailed
    42 2026 Proxy Statement

    ​
    Item 2: Approval of Employee Stock Purchase Plan
    or complete description of all U.S. federal tax laws or regulations that may apply and does not address any local, state or other country laws. Therefore, no one should rely on this summary for individual tax compliance, planning or decisions. Participants in the ESPP should consult their own professional tax advisors concerning tax aspects of participation in the ESPP. Participant contributions to the ESPP are made on an after-tax basis. There is no taxable event on the purchase date with respect to shares of common stock purchased under the ESPP because such shares are purchased at their fair market value. However, any matching grant provided to a participant will be taxable compensation to the participant. Valmont will generally be entitled to a deduction at such time equal to the value of the matching grant to the participant, subject to the limitations of Section 162(m) of the Internal Revenue Code. Any further appreciation or depreciation in shares purchased or otherwise issued under the ESPP will be treated as capital gain or loss when the shares are sold by the participant. The capital gain or loss will be long-term if the participant has held the shares for more than one year or otherwise will be short-term.
    New Plan Benefits
    Levels of participation in the ESPP are not currently determinable and, accordingly, Valmont is unable to predict the number of shares that may be purchased thereunder, or matching grants that will be made thereunder to any specific participant. However, Section 16 officers, including our named executive officers, and our board of directors are not eligible to participate in the ESPP.
    THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” APPROVAL OF ITEM 2.
    2026 Proxy Statement 43

    ​
    Item 3: Advisory Vote on Executive Compensation
    Valmont is asking its shareholders to provide advisory approval of the compensation paid to named executive officers. Shareholders are being asked to vote on the following resolution:
    RESOLVED, that the shareholders approve, on an advisory basis, the compensation paid to the Company’s named executive officers, as disclosed in the Company’s proxy statement for the 2026 annual meeting of shareholders pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the compensation tables and the related narrative discussion.
    The Company believes that its compensation programs have served to achieve the objectives of attracting highly competent executives, enhancing long-term growth and shareholder value, and assuring compensation at appropriate levels based on performance.
    Valmont conducted its first advisory vote on executive compensation in April 2011. The compensation resolution has passed with over 95% of the vote every year since 2011, including 96.3% of the vote in 2025. Valmont’s shareholders in April 2023 cast 97.0% of their votes in favor of an annual frequency for the say-on-pay vote. The board of directors and the Human Resources Committee considered these results in determining compensation policies and decisions, and determined to hold annual say-on-pay votes and, based on the significant level of shareholder support, to continue the current compensation objectives, strategies, processes and practices described below.
    COMPENSATION OBJECTIVES, STRATEGIES, PROCESSES AND PRACTICES
    The Company encourages shareholders to read about its compensation objectives, strategies, processes and practices in the Compensation Discussion and Analysis. Some of the more significant elements of the compensation practices are:

    ​
    ■
    Long-Term Performance Incentives. Long-term incentives are performance based. The three-year performance period which ended in 2025 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), weighted 70% ROIC and 30% OIG. The Human Resources Committee established in February 2023 the targets for the three-year performance cycle ending in 2025. The targets were established at OIG growth of 5% and average ROIC of 14.0%. The adjusted three-year growth in OIG of 2.30% and the adjusted three-year average ROIC of 14.60% (see Compensation Discussion and Analysis) resulted in payouts under the 2023-2025 long-term incentive plan at 102.9% of target. The Company stock price during the performance period increased from a start date 30 day average of $332.59 to $412.20 which increased the value of the earned PSUs. The earnouts for the prior nine fiscal years were as follows as a percentage of target:
    ​
    ​ 2024 ​ ​ ​ ​ 200.0% ​ ​
    ​ 2023 ​ ​ ​ ​ 200.0% ​ ​

    ​ 2017 ​ ​ ​ ​ 0% ​ ​
    ​ 2016 ​ ​ ​ ​ 0% ​ ​
    ​
    ■
    Equity Incentives. Stock options and RSUs are also a form of long-term incentive. The Human Resources Committee established the terms and provisions of equity awards granted in 2025 based on industry standards as provided by its independent compensation consultant. The number of options and RSUs 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 equity awards granted to named executive officers during 2025 is at Grants of Plan Based Awards for Fiscal 2025.
    ​
    This advisory resolution, commonly referred to as a “say-on-pay” resolution, is nonbinding on the board of directors. Although nonbinding, 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.

    Audit Committee Report
    The Audit 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 oversees the Company’s risk with respect to operational, compliance and financial matters, including legal, insurance, information technology and cybersecurity matters. 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 investors.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 2025 was compatible with the auditor’s independence.
    The Committee reviewed and discussed the Company’s audited financial statements for fiscal 2025 with both management and Deloitte.

    Item 4: Ratification of Appointment of Independent Auditors
    On March 3, 2026, following the conclusion of a process managed by the Audit Committee, the Audit Committee approved the appointment of KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm beginning with the year ending December 26, 2026 and related interim periods.
    During the Company’s fiscal years ended December 27, 2025 and December 28, 2024 and through March 3, 2026, neither the Company, nor anyone on its behalf, consulted KPMG regarding either: (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on the Company’s financial statements and no written report or oral advice was provided to the Company by KPMG that KPMG concluded was an important factor considered by the Company in reaching a decision as to an accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a “disagreement” as that term is defined in Item 304(a)(1)(iv) of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended, or Regulation S-K, and the related instructions thereto, or “reportable event” as described in Item 304(a)(1)(v) of Regulation S-K.
    In connection with the appointment of KPMG, on March 3, 2026, the Audit Committee dismissed Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm.
    During the Company’s years ended December 27, 2025 and December 28, 2024 and through March 3, 2026, there were no: (1) “disagreements” with Deloitte as defined in Item 304(a)(1)(iv) of Regulation S-K and related instructions thereto, on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements, if not resolved to their satisfaction, would have caused them to make reference in connection with their opinion to the subject matter of the disagreement, or (2) “reportable events” as described in Item 304(a)(1)(v) of Regulation S-K.
    The audit reports of Deloitte on the Company’s consolidated financial statements as of and for the Company’s fiscal years ended December 27, 2025, and December 28, 2024, did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles.
    Deloitte and the member firms of Deloitte Touche Tohmatsu, and their respective affiliates (collectively Deloitte) conducted the 2025 and 2024 audits of the Company’s financial statements. Fees billed by Deloitte to the Company for services provided during the 2025 and 2024 fiscal years were as follows:
    ​ ​ ​ ​
    2025
    ​ ​
    2024
    ​
    ​ Audit Fees ​ ​ ​ $ 3,406,780 ​ ​ ​ ​ $ 3,113,873 ​ ​
    ​ Audit-Related Fees ​ ​ ​ $ 50,500 ​ ​ ​ ​ $ 178,500 ​ ​
    ​ Tax Fees ​ ​ ​ $ 197,300 ​ ​ ​ ​ $ 130,448 ​ ​
    ​ Other Fees ​ ​ ​ $ 36,895 ​ ​ ​ ​ $ 1,895 ​ ​
    ​ Total Fees ​ ​ ​ $ 3,691,475 ​ ​ ​ ​ $ 3,424,716 ​ ​
    Audit Fees consist of the audit of the Company’s fiscal 2025 and 2024 annual financial statements, review of the Company’s quarterly financial statements during 2025 and 2024, 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-Related Fees consist of financial statement audits of employee benefit plans, consents related to Securities and Exchange Commission filings, procedures in connection with SEC registration statements, comfort letters provided in connection with the issuance of debt, 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.
    Tax Fees consist of international tax planning and federal, state and expatriate tax compliance.
    The Audit 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 Audit 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 Audit Committee. In periods between Audit Committee meetings, the Audit Committee Chair has the delegated authority to pre-approve additional services, and such pre-approvals are then communicated to the full Audit Committee.
    2026 Proxy Statement 47

    ​
    The Audit Committee requests that the shareholders ratify the appointment of KPMG as the Company’s independent registered accounting firm for the 2026 fiscal year and related interim periods. In addition to KPMG’s independence, the Audit Committee considered KPMG’s capabilities, qualifications and expertise, the effectiveness and efficiency of KPMG’s proposed audit services, the appropriateness of KPMG’s proposed fees, and the benefits of a fresh perspective. A representative from KPMG will be present at the Annual Meeting 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 of KPMG, the appointment will be reconsidered by the Audit Committee.

    Delinquent Section 16(a) Reports
    Section 16(a) of the Securities Exchange Act of 1934 requires executive officers and directors to file reports of changes in ownership of the Company’s common stock with Securities and Exchange Commission. Executive officers and directors are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms so filed. Based solely on a review of the copies of such forms furnished to the Company and written representations from the Company’s executive officers and directors, the Company believes that all persons subject to these reporting requirements filed the required reports on a timely basis during fiscal 2025 except initial Form 3s for Christopher Colwell and Gregory Turi, who were named executive officers on April 28, 2025 were delayed until May 20, 2025 and June 4, 2025, respectively, due to administrative difficulties in obtaining their Edgar filing codes for new filers in connection with the SEC’s implementation of EDGAR Next.
    Shareholder Proposals
    Shareholder proposals intended to be presented at the 2027 annual meeting of shareholders must be received by the Company no later than November 11, 2026 in order to be considered for inclusion in the proxy statement for such meeting.

If the date of the 2027 annual shareholders’ meeting is advanced by more than 30 days or delayed by more than 60 days from the anniversary date, then the notice must be received no earlier than the 120th day prior to such annual meeting and not later than the later of the close of business on the 90th day prior to such annual meeting or the tenth day following the date on which public announcement of the meeting date is first made.
    To comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees at the 2027 Annual Meeting other than our nominees must provide notice that sets forth the information required by Rule 14a-19 under the Securities Exchange Act no earlier than December 28, 2026 and no later than January 27, 2027.
    The bylaws specify the information which must accompany any such shareholder notice. Details of the provision of the bylaws may be obtained by any shareholder from the Secretary of the Company.
    The Company’s proxy card for the 2026 annual shareholders’ meeting will give discretionary authority with respect to any shareholder proposals properly brought before the 2026 annual shareholders’ meeting that are not included in this proxy statement.
    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. 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.

    ​
    (b)
    Amount of Payroll Deductions. An Eligible Employee shall designate on the Election Form the portion of his or her Compensation that he or she elects to have withheld for the purchase of Stock hereunder. Such portion may be a whole percentage of the Eligible Employee’s Compensation, but not less than 1% nor more than 10%.

    SECTION 7. WITHDRAWAL FROM THE PLAN.
    (a)
    Withdrawal. Each Participant who is an Eligible Employee may withdraw from a Purchase Period by filing a new Election Form. Such withdrawal may be elected at any time, and will be effective as soon as administratively practical following receipt thereof.

    ​
    (b)
    Return of Payroll Deductions. Upon withdrawal from the Plan and unless otherwise determined by the Committee, any accumulated payroll deductions shall be returned, without interest, to the withdrawn Eligible Employee and his or her interest in the Plan shall terminate.
    ​
    SECTION 8. CHANGE IN ELIGIBLE EMPLOYEE STATUS.

    2026 Proxy Statement A-3

    ​
    Appendix
    (c)
    Matching Contributions. On each Purchase Date, the Company shall make a contribution of fully vested Stock to each Participant (a “Matching Award”) equal to one-third of the number of shares of Stock purchased on behalf of such Participant through this Plan on such Purchase Date (the “Matching Ratio”). The Committee (or its delegate) shall determine the method by which the Matching Award will be administered for any Purchase Period, Participating Employer, or jurisdiction (each, the “Matching Method”), which may be: (i) delivery of additional shares of Stock (“Matching Shares”) equal to the Matching Ratio multiplied by the number of shares of Stock purchased by the Participant on the Purchase Date; or (ii) a cash credit to the Participant’s Plan Account equal to the Matching Ratio multiplied by the dollar amount of the Participant’s contributions actually applied to purchase shares of Stock on the Purchase Date (“Matching Dollars”). If the application of the Matching Ratio would result in a Matching Award of a fraction of a share, the fraction will instead be awarded as a fractional share contribution notationally allocated to the Participant, to be aggregated with other notional fractional shares on future Purchase Dates. Such Company contributed shares of Stock may be purchased on the open market by the Company or issued from authorized but unissued or treasury shares. In accordance with Section 20 hereof, the Company shall be permitted to issue such shares of Stock net of applicable taxes.
    ​
    (d)
    Number of Shares Purchased via Participant Contribution. On each Purchase Date, the Company shall apply the funds then credited to each Participant’s Plan Account to the purchase of shares of Stock. As of each such Purchase Date, each such Participant shall purchase the number of shares of Stock calculated in accordance with this subsection (d), unless the Participant has previously elected to withdraw from the Plan in accordance with Section 7; provided, however, that no Stock shall be purchased on a Purchase Date on behalf of any Participant whose participation in the Plan was terminated prior to such Purchase Date. On each Purchase Date, the amount of funds then in the Participant’s Plan Account shall be divided by the Purchase Price, and the number of shares that results shall be purchased with the funds credited to the Participant’s Plan Account. Any fractional share purchased shall be notationally allocated to the Participant.
    ​
    (e)
    Issuance of Stock. Promptly following each Purchase Date, the shares of Stock purchased by each Participant and contributed by the Company shall be deposited into an account established in the Participant’s name at a stock brokerage or other financial services firm designated by the Company (with fractional shares notationally allocated as provided herein).
    ​
    (f)
    Fractional Shares. No Participant shall have any right to receive any notationally allocated fractional share, nor shall any provision herein be construed to give such right. Upon ceasing to be an Eligible Employee or withdrawal from the Plan under Section 7, any notionally allocated fractional share shall be paid thereto in cash to the Participant. Any such payment in respect of a notionally allocated fractional share shall be in an amount equal to its fractional equivalent of the Market Value as of the time of ceasing to be an Eligible Employee or such withdrawal.
    ​
    SECTION 10. DOLLAR LIMITATIONS ON STOCK PURCHASES.
    Notwithstanding anything to the contrary in this Plan, the maximum amount that a Participant may use to purchase shares of Stock under this Plan in any calendar year is U.S. $3,000.
    SECTION 11. RIGHTS NOT TRANSFERABLE.
    Neither payroll deductions credited to a Participant’s Plan Account nor any rights to receive shares of Stock under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will, the laws of descent and distribution or as provided in Section 18 hereof) by the Participant. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect.
    SECTION 12. NO RIGHTS AS AN EMPLOYEE.
    Nothing in the Plan or in any right granted under the Plan shall confer upon the Participant any right to receive any benefits in the future under this Plan, to continue in the employ of a Participating Employer, to be an Eligible Employee for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Participating Companies or of the Participant, which rights are hereby expressly reserved by each, to terminate the Participant’s employment at any time and for any reason, with or without cause.
    SECTION 13. NO RIGHTS AS A STOCKHOLDER.
    A Participant shall have no rights as a stockholder with respect to any shares of Stock that he or she may have a right to purchase under the Plan until such shares have been purchased on the applicable Purchase Date.
    SECTION 14. COMPANY INTENT
    It is intended that the Plan comply with the requirements of Section 409A of the Code, to the extent applicable. The Plan and all Election Forms (or similar documents) will be construed in a manner that effects such intent. Nevertheless, the tax treatment of the benefits provided

    This Plan shall be effective upon approval of the stockholders of the Company and shall continue until terminated by the Board. The Board may at any time suspend or terminate the Plan. The Company may, by written resolution of the Board or the Committee, at any time and from time to time, amend the Plan in whole or in part, which as appropriate may include sub-plans, including to provide flexibility, if necessary, for non-U.S. Employee participation; provided, however, the Board or the Committee may not make any amendment which would (i) except as permitted by Section 2(h), materially modify the requirements for participation in the Plan, or (ii) except a permitted by Section 3, increase (a) the number of shares of Stock authorized under the Plan set forth in Section 3, (b) the Match Ratio set forth in Section 9(c) or (c) the $U.S. 3,000 purchase limit set forth in Section 10, in each case without the approval of a majority of the outstanding shares of Stock present and in person or represented by proxy and entitled to vote at the meeting thereon.

    (a)
    Designation. A Participant may file a designation of a beneficiary on a form provided by the Company who is to receive the cash, if any, that remains allocated to the Participant’s Plan Account in the event of such Participant’s death.

    ​
    (b)
    No Designation. In the event of the death of a Participant in the absence of a beneficiary validly designated under the Plan who is living at the time of such Participant’s death, the Company shall deliver such cash to the executor or administrator of the estate of the Participant, or if no such executor or administrator has been appointed (to the knowledge of the Company), the Company, in its sole discretion, may deliver such cash to the spouse or to any one or more dependents or relatives of the Participant, or if no spouse, dependent or relative is known to the Company or then surviving, then to such other person as the Company may designate.
    ​
