Apogee Enterprises (NASDAQ: APOG) outlines 2026 pay, equity plan and board votes

Rhea-AI Filing Summary

Apogee Enterprises is asking shareholders to approve four items at its 2026 virtual annual meeting, including electing two Class I directors, an advisory vote on executive pay, expanding its 2019 Stock Incentive Plan, and ratifying Deloitte & Touche as auditor.

For fiscal 2026, Apogee generated net sales of $1.40 billion, up from $1.36 billion, but operating income fell to $84.5 million and diluted EPS declined to $2.52 from $3.89. Adjusted EBITDA was $167.3 million, down from $192.7 million. The company repurchased 388,582 shares for $15.0 million, paid $22.2 million in dividends, and raised its quarterly dividend 4% to $0.27 per share.

The proxy details a performance-focused pay program with significant equity, new offer letters for the CEO and CFO, and an increase in shares authorized under the stock plan from 2,150,000 to 2,950,000. The board highlights majority independence, diversity, a strong committee structure, and active shareholder engagement.

Insights

Corporate governance and compensation analyst

Apogee pairs softer earnings with active capital returns and refreshed leadership pay.

Apogee Enterprises reports higher fiscal 2026 net sales of $1.40 billion but lower profitability, with operating income down to $84.5 million and diluted EPS at $2.52. Adjusted EBITDA of $167.3 million and weaker (14.70)% one-year TSR frame a more challenging year.

The proxy emphasizes performance-based pay: substantial equity awards, Adjusted EBITDA as the primary short-term metric, and three-year Adjusted Diluted EPS and Adjusted ROIC for long-term incentives. New CEO and CFO offer letters add sizable one-time equity grants while maintaining double-trigger change-in-control protections and clawbacks.

Capital allocation included $15.0 million of share repurchases and $22.2 million of dividends, including a 4% dividend increase. The proposal to lift stock plan capacity from 2,150,000 to 2,950,000 shares modestly increases potential equity usage. Future disclosures in periodic reports will show whether the refined strategy and AMS initiatives translate into improved margins and TSR.

6 terms

Adjusted EBITDA financial

"Beginning in fiscal 2026, the Company transitioned from Operating Income to Adjusted EBITDA as the primary metric of operating performance"

Adjusted EBITDA is a way companies measure how much money they make from their core operations, like running a business, by removing certain costs or income that aren’t part of regular business activities. It helps investors see how well a company is doing without distractions from unusual expenses or gains, making it easier to compare companies or track performance over time.

Adjusted Diluted EPS financial

"Performance awards are based 60% on our three-year cumulative adjusted diluted earnings per share ("Adjusted Diluted EPS")"

Adjusted diluted EPS is a company’s profit per share after adding back or removing one-time items (like restructuring costs or gains) and dividing by the number of shares including potential shares from options and convertible securities. Investors use it as a cleaner view of ongoing earnings—like looking at a car’s regular fuel efficiency rather than a trip boosted by downhill coasting—to judge underlying performance and compare companies without temporary distortions.

Apogee Management System (AMS) other

"Apogee Management System (AMS) continued to drive improvements across our manufacturing footprint"

Enterprise Risk Management ("ERM") financial

"The Company's Enterprise Risk Management ("ERM") committee assists us in achieving our business objectives"

double-trigger change-in-control agreements financial

"Our “double-trigger” change-in-control agreements do not provide for any excise tax “gross-ups,”"

Say on Pay Proposal financial

"At our Company’s 2025 Annual Meeting of Shareholders... votes cast on the Say on Pay Proposal were voted in favor"

Fiscal 2026 Financial Results

We are a leading provider of architectural building products and services, as well as high-performance coated materials used in a variety of applications. Our four reporting segments are: Architectural Metals, Architectural Services, Architectural Glass, and Performance Surfaces.

Fiscal 2026 was a year of disciplined execution for Apogee as we navigated a difficult economic environment while continuing to strengthen our operating foundation. We executed our priorities for the year including:

•The Performance Surfaces Segment successfully integrated UW Interco, LLC (UW Solutions), acquired in late fiscal 2025, and the business delivered on the first-year financial targets of $100 million in revenue and adjusted EBITDA margin of at least 20%.

•Apogee Management System (AMS) continued to drive improvements across our manufacturing footprint including enabling progress improving outcomes for customers in the Architectural Metals Segment through full value‑stream redesign, supported by a new product and manufacturing site. These enhancements drove higher service levels and shorter lead times while reducing cost of poor quality.

•We actively managed our cost structure and manufacturing footprint through Project Fortify 2 ("Project Fortify Phase 2" or "Phase 2") to mitigate portions of direct and indirect tariffs while driving efficiencies across the organization. While these decisions were challenging and disruptive, we are confident that the actions will further position Apogee to successfully navigate the market headwinds into the future.

We also delivered meaningful gains in safety, service, and productivity, and generated solid cash flow.

(1)Beginning in fiscal 2026, the Company transitioned from Operating Income to Adjusted EBITDA as the primary metric of operating performance for our short-term cash incentive program. Adjusted EBITDA is a non-GAAP financial measure. See "Use of Non-GAAP Financial Measures" on page 36.

(2)TSR is the cumulative return on a share of Apogee common stock over the specified period, assuming reinvestment of dividends, calculated as a percentage change in stock price plus dividends paid.

Executive Compensation Program

Our compensation programs are designed to attract, motivate and retain executive talent to achieve success in both the short- and long-term for our Company; pay for sustainable performance in an ever-changing environment; and align the interests of our executive officers with our shareholders. We continue to refine our executive compensation program to reflect changes in our business strategy and evolving executive compensation practices.

Executive Compensation Highlights

•Our compensation program prioritizes pay for performance. A significant portion of our compensation program is at risk and performance-based, through the use of short- and long-term incentive plans that have multiple financial performance metrics.

•We annually disclose Company performance against the established performance metrics for our short-term cash incentive in our proxy statement.

•Our long-term incentive compensation program consists of annual restricted stock awards that vest over three years and annual performance awards with overlapping three-year performance periods that vest at the end of the performance period. Performance awards are based 60% on our three-year cumulative adjusted diluted earnings per share ("Adjusted Diluted EPS") and 40% on our three-year average adjusted return on invested capital (“Adjusted ROIC”) over the performance period and settle 50% in shares and 50% in cash. (Adjusted Diluted EPS and Adjusted ROIC are non-GAAP financial measures. See "Use of Non-GAAP Financial Measures" on page 36.)

•We deliver a significant portion of potential total compensation to our executive officers in the form of equity, which enhances our executives' alignment with shareholders.

•We have stock ownership guidelines for our Chief Executive Officer that require an ownership level of five times their annual base salary, three times their annual salary for our Chief Financial Officer, two times their annual salaries for certain corporate executive officers, including segment presidents, and one time their annual salaries for other corporate executives.

•We have compensation recoupment, or “clawback” policies that we amended in 2023 to comply with the incentive compensation recovery rules adopted by the SEC and Nasdaq.

•We have a hedging policy that prohibits all employees and directors from engaging in hedging transactions in our Company’s securities. We also have an anti-pledging policy that prohibits executive officers and directors of the Company from, directly or indirectly, pledging, hypothecating, or otherwise encumbering shares of the Company’s common stock as collateral for indebtedness. None of our executive officers have pledged any shares of our common stock as security or collateral on a personal loan.

•Our “double-trigger” change-in-control agreements do not provide for any excise tax “gross-ups,” and we do not provide any tax “gross-ups” on any benefits for our executive officers.

Fiscal 2026 Executive Compensation Actions

•Base Salaries. Mr. Nolan, the former Independent Chair of our Board of Directors, was appointed Chief Executive Officer and Executive Chair of the Board of Directors effective as of the close of business on October 31, 2025, earning an annualized base salary of $925,000, which is described more fully under "New Chief Executive Officer Offer Letter" beginning on page 5. Mr. Augdahl was appointed as our Executive Vice President and Chief Financial Officer effective January 19, 2026, earning an annualized base salary of $550,000, which is described more fully under "New Chief Financial Officer Offer Letter" on page 6. For returning Named Executive Officers, base salary increases ranged from 1.76% to 4.02% except for Mr. T. Johnson who received an 18.00% increase for his reassignment to the position of President, Architectural Metals Segment, effective August 7, 2025. See “Fiscal 2026 Individual Compensation Actions” beginning on page 42 for a discussion of factors considered in establishing base salaries and subsequent increases.

•Short-Term Cash Incentive Payouts. Our short-term cash incentive awards are designed to reward achievement of financial goals established in our annual operating plan. Mr. Nolan has a short-term cash incentive plan that pays out based on his performance during the Term of the CEO Offer Letter, as described under "Nolan Short-Term Cash Incentive Plan" beginning on page 46. Mr. Silberhorn, our former Chief Executive Officer, received a short-term cash incentive payout equal to 50% ($466,000) of the target pursuant to the terms of his Separation Agreement. For Mr. Augdahl, whose payout was based on consolidated performance metrics, the fiscal 2026 short-term cash incentive paid out at 21.17% of target. For Messrs. T. Johnson and Jewell and Ms. Lakkundi, whose payouts were based on segment as well as consolidated performance metrics, the fiscal 2026 short-term cash incentive paid out at 100% for Mr. T.

We added Adjusted Diluted EPS as a metric in fiscal 2025 in order to diversify and balance our performance metrics, incentivizing earnings growth as well as return on invested capital. The Other Named Executive Officers received restricted stock awards with values ranging from $877,797 to $1,211,659 and performance awards with target values ranging from $176,505 to $503,995.

The feedback from our engagement with investors is regularly shared with our Board of Directors.

Delinquent Section 16(a) Reports

Section 16(a) of the Securities Exchange Act of 1934 requires our directors, officers and all persons who beneficially own more than 10% of the outstanding shares of common stock to file with the SEC initial reports of ownership and reports of changes in ownership of our common stock.

Based solely on a review of Section 16(a) reports filed electronically with the SEC and written representations from certain reporting persons, we believe that all forms required to be filed by such persons under Section 16(a) were filed on a timely basis, with the exception of the following late filings:

•One filing for Matthew S. Christian - an initial Form 3 report of common stock ownership required on August 7, 2025, which was filed on September 11, 2025;

•Two filings for Mark R. Augdahl - an initial Form 3 report of common stock ownership required on January 19, 2026, which was filed on February 20, 2026, and a Form 4 reporting an award granted on January 19, 2026, which was filed on February 20, 2026; and

Each of the filings was delinquent because of delays in obtaining access to the new EDGAR Next platform.

Proposal 1: Election of Directors

Our Articles provide that our Board of Directors will be divided into three classes of directors of as nearly equal size as possible and the term of each class of directors is three years. The term of one class expires each year in rotation. Currently, we have seven directors, with three directors serving in Class I, two directors serving in Class II and two directors serving in Class III. At our Annual Meeting, the terms of our two Class I directors will expire. Class I director Lloyd E. Johnson will retire from the Board of Directors and will not stand for re-election at the Annual Meeting. Mr. L. Johnson will continue to serve as a director until the date of the Annual Meeting. Immediately following the certification of the vote for the election of directors at the Annual Meeting, the size of the Board will be reduced to six, with two directors in each class. Effective as of the close of business on October 31, 2025, Class II director Ty R. Silberhorn separated from the Company and the Board of Directors, and Class I director Donald A. Nolan was appointed Chief Executive Officer and Executive Chair.

Donald A. Nolan and Patricia K. Wagner have been nominated for re-election to our Board as Class I directors. Class I directors re-elected at the Annual Meeting will serve until our 2029 Annual Meeting of Shareholders and until their successors are duly elected and qualified or until their earlier resignation or removal. Each of the nominees has agreed to serve as a director, if re-elected.

If any of the nominees becomes unable or unwilling to serve as a director prior to the Annual Meeting, proxies will be voted for a substitute nominee or nominees designated by the Board. Alternatively, at the Board’s discretion, the proxies may be voted for a fewer number of nominees.

Information about the background and qualifications of the Board nominees standing for re-election at the Annual Meeting and the directors continuing to serve after the Annual Meeting who are not subject to re-election at the Annual Meeting is provided below.

Board Recommendation

Our Board of Directors recommends that you vote FOR the two Class I director nominees. Unless a contrary instruction is indicated on the proxy, proxies will be voted FOR the election of the two Class I director nominees.

For employees suspecting a violation of our Code of Conduct, we maintain an independent hotline available 24/7 that allows both anonymous and confidential reporting.

Corporate Governance Guidelines

Our Corporate Governance Guidelines outline the role, composition, qualifications, operation and other policies applicable to our Board of Directors and are revised as necessary to reflect evolving corporate governance practices.

Communications with Our Board of Directors

Our stakeholders may communicate directly with our Board of Directors, our Lead Director or any other specified individual director in writing by (i) sending a letter addressed to Apogee Directors, Apogee Enterprises, Inc., 4400 West 78th Street, Suite 520, Minneapolis, Minnesota 55435, or (ii) sending an email to Directors@apog.com. Substantive communications, such as corporate governance matters or potential issues relating to accounting, internal controls or other auditing matters, are forwarded by our General Counsel to the relevant director(s) as appropriate. Communications not requiring the substantive attention of our Board, such as employment inquiries, sales solicitations, donation requests, questions about our products, and other such matters, are handled directly by our management team.

Director Independence

Under our Corporate Governance Guidelines, a substantial majority of the directors on our Board, and all members of our Audit, Compensation, and Nominating and Corporate Governance Committees (collectively, the “Committees”) must be independent. Each year, in accordance with Nasdaq rules, our Board of Directors affirmatively determines the independence of each director and nominee for election as a director in accordance with guidelines it has adopted, which include all elements of independence set forth in the Nasdaq listing standards and applicable SEC rules.

Our Nominating and Corporate Governance Committee reviewed the applicable legal standards for Board member and Committee member independence and reported on its review to our Board of Directors. Based on this review, our Board of Directors has determined that the following non-employee directors are independent and have no material relationship with the Company except serving as a director and holding shares of our common stock: Christina M. Alvord, Lloyd E. Johnson, Elizabeth M. Lilly, Herbert K. Parker, Mark A. Pompa and Patricia K. Wagner. Our current Chief Executive Officer and Executive Chair, Donald A. Nolan, served as Chair of the Board of Directors until the close of business on October 31, 2025 and was considered independent during that period. At the close of business on October 31, 2025, upon his election as Chief Executive Officer and Executive Chair of the Board, Mr. Nolan ceased to be independent. Our Board of Directors had determined that our former Chief Executive Officer Ty R. Silberhorn was not independent because he served as an officer of the Company.

Board Leadership Structure

The Board recognizes that there are circumstances when combining the Chairman of the Board and Chief Executive Officer roles may be appropriate, such as for an interim period when either leader becomes incapacitated, or in the course of the Chairman of the Board or Chief Executive Officer transitions.

At the close of business on October 31, 2025, the Board appointed our Chair of the Board, Mr. Nolan, as our Chief Executive Officer and Executive Chair of our Board of Directors. This election was made after careful consideration by the Board after Mr. Silberhorn resigned from his position as President and Chief Executive Officer and a member of our Board of Directors. Mr. Nolan had served as our Independent Chair since January 2020.

Ms. Wagner, a current member of our Board, was elected as Lead Director, on October 31, 2025. Ms. Wagner then resigned as Lead Director on January 14, 2026, and Mr. Pompa was elected as Lead Director on January 14, 2026. The Lead Director serves as the de facto leader of Apogee's independent directors and the focal point for ensuring that the Board of Directors, as a whole, is providing appropriate independent oversight of management. Our Company's Corporate Governance Guidelines explicitly mandate that the Board retains the right to exercise its discretion in combining or separating the offices of the Chairman of the Board and Chief Executive Officer. This determination will be made depending upon what the Board believes is best for Apogee in light of all circumstances at any particular time. When the position of Chairman of the Board is not held by an independent director, the Board will appoint a Lead Director who will have the duties and authority set forth below.

The Lead Director position will be held by an independent director. The Lead Director shall (i) preside at all meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors; (ii) serve as a liaison between the Chairman and the independent directors (including communicating feedback from executive sessions of independent directors); (iii) seek input from the independent directors with respect to Board meeting agendas; (iv) approve meeting agendas for the Board; (v) approve Board meeting schedules to assure that there is sufficient time for discussion of all agenda items; (vi) establish guidelines for management with respect to the quality, quantity and timeliness of information sent to the Board; (vii) have the authority to call meetings of the non-employee directors; (viii) facilitate discussions among independent directors with respect to key issues or concerns of such directors between Board meetings; (ix) approve the retention of outside advisors and consultants who report directly to the Board on board-wide issues; and (x) if requested by major shareholders, ensure that he or she is available for consultation and direct communications with such shareholder.

22

The Board understands the importance of this leadership decision and thoroughly explored different structures and a wide range of considerations through an open-minded decision-making process. In reaching its decision to combine the roles under Mr. Nolan, the Board evaluated the best leadership structure for the Company in the context of its present circumstances, taking into account the Company's strategic needs over the next phase of its transformation, Mr. Nolan's leadership qualities, the independence of the Board, and the strength of the Lead Director role.

Criteria for Membership on Our Board of Directors

Director candidates should possess the highest personal and professional ethics, integrity and values; be committed to representing the long-term interests of our stakeholders; have an inquisitive and objective perspective, practical wisdom and mature judgment; and be willing to challenge management in a constructive manner. Our Board of Directors strives for membership that is diverse in gender, race, ethnicity, age, geographic location, and business skills and experience at policy-making levels.

Director Time Commitment and Other Board Service

In addition, director candidates must be willing to devote sufficient time to carrying out their duties and responsibilities and should be committed to serving on our Board of Directors for an extended period of time. It is the policy of the Board that a non-employee director should not serve on the board of directors of more than four other publicly held corporations unless approved by the majority of the directors.

Procedure for Evaluating Director Nominees

Our Nominating and Corporate Governance Committee’s procedure for reviewing the qualifications of all nominees for membership on our Board of Directors includes making a preliminary assessment of each proposed nominee based upon resume and biographical information, willingness to serve and other background information, business experience and leadership skills. Our Board believes that its membership should reflect a diversity of experience, skills, geography, gender, race and ethnicity, and invites directors to annually self-identify certain diversity characteristics that may inform their perspectives and contributions to the Board. The Committee considers each of these factors when evaluating our Board composition, and it considers these factors on an ongoing basis as it identifies and evaluates director candidates. All director candidates who continue in the process are then interviewed by members of our Nominating and Corporate Governance Committee and other current directors. Our Nominating and Corporate Governance Committee makes recommendations to our Board of Directors for inclusion in the slate of director nominees at a meeting of shareholders, or for appointment by our Board of Directors to fill a vacancy. Prior to recommending a director to stand for re-election for another term, our Nominating and Corporate Governance Committee applies its director candidate selection criteria, including a director’s past contributions to our Board of Directors, effectiveness as a director, and desire to continue to serve as a director.

Board Refreshment and Retirement Policy

Our Company has an active board refreshment program. As a mechanism to encourage director refreshment, our Board of Directors has established a policy that no individual may stand for election to our Board after their 72nd birthday, unless otherwise approved by a majority of our directors.

All of our directors have served on our Board six or more years.

Stock Ownership Guidelines for Non-Employee Directors

Our Board of Directors has established director stock ownership guidelines that encourage share ownership by our directors of four times an amount equal to the annual Board retainer to be achieved within five years of first being elected as a director. For fiscal 2026, the annual Board retainer was $75,000. In calculating share ownership of our non-employee directors, we include shares of restricted stock, restricted stock units and deferred restricted stock units issued pursuant to our 2009 Director Stock Plan, 2019 Director Stock Plan and phantom stock units issued pursuant to our prior Deferred Compensation Plan for Non-Employee Directors. Shares are valued based on the average closing price of our common stock for the most recently completed

23

fiscal year. As of February 27, 2026, the last trading day of fiscal 2026, all our non-employee directors exceeded our stock ownership guidelines.

Board Meetings and 2025 Annual Meeting of Shareholders

During fiscal 2026, our Board of Directors met eight times and our non-employee directors met in executive session without our Chief Executive Officer or any other members of management being present at each regular meeting. Each of our directors attended more than 75% of the regularly scheduled and special meetings of our Board of Directors and our Committees on which they served during fiscal 2026.

All members of our Board of Directors are expected to attend our annual meeting of shareholders, and all members of our Board of Directors who continued to serve on our Board after our 2025 Annual Meeting of Shareholders attended such meeting via the virtual meeting platform.

Board Committee Responsibilities, Meetings and Membership

We currently have three standing Committees: Audit, Compensation, and Nominating and Corporate Governance. Each Committee operates under a written charter that is available on our website at www.apog.com by clicking on “Investors” and selecting “Governance” and then clicking on the applicable Board Committee. Each Committee member meets the applicable independence and experience requirements of the Nasdaq listing standards and the SEC for the Committees on which they serve. While our Committees are responsible for various aspects of our environmental, social and governance sustainability program, currently our full Board oversees the Company's strategies and material initiatives relating to corporate responsibility, including cybersecurity and climate-related risk.

Risk Oversight by Our Board of Directors and Management

Committee Roles in Risk Management

Our Board of Directors oversees our enterprise risk management processes, focusing on our business, strategic, financial, operational, information technology, cybersecurity, climate-related and overall enterprise risk. Our Board determined that oversight of our Company’s strategy and overall enterprise risk management program is more effective when performed by the full Board, utilizing the skills and experiences of all directors. In addition, our Board of Directors executes its overall responsibility for risk management through its Committees as follows:

•Our Audit Committee has primary responsibility for risk management relating to the reliability of our financial reporting processes, system of internal controls and corporate compliance program. Our Audit Committee receives quarterly reports from management, our independent registered public accounting firm and the Company's internal audit function regarding our financial reporting processes, internal

26

controls and public filings. It also receives quarterly updates from management regarding Code of Conduct matters, litigation and legal claims, and other compliance matters.

•Our Compensation Committee, with assistance from its independent compensation consultant, oversees risk management associated with our compensation programs, policies and practices with respect to both executive compensation and compensation in general, and reviews human capital management matters including diversity, equity and inclusion.

•Our Nominating and Corporate Governance Committee oversees risk management associated with succession planning, non-employee director compensation, overall Board of Directors and Board Committee performance, and corporate governance practices.

Management's Role in Risk Management

The Company's Enterprise Risk Management ("ERM") committee assists us in achieving our business objectives by creating a systematic approach to anticipate, analyze and review material risks. The ERM committee meets with the Company's executives and senior leaders, and presents to the Board at least twice per year on the probability, potential impact and timeframe of impact of the identified risks.

Sustainability and Human Capital Resources

At Apogee, our Core Values are the foundation of our culture, and they are reflected in our commitment to sustainability and to developing our employees to their full potential.

Certain Relationships and Related Transactions

We have established written policies and procedures (the “Related Person Transactions Policy”) to assist us in reviewing transactions in excess of $120,000 involving our Company and our subsidiaries and Related Persons (“Related Persons Transactions”). A Related Person includes our Company’s directors, director nominees, executive officers and beneficial owners of 5% or more of our Company’s common stock and their respective Immediate Family Members (as defined in our Related Person Transactions Policy). Our Related Person Transactions Policy supplements our Code of Business Ethics and Conduct Conflict of Interest Policy, which applies to all of our employees and directors.

Our Related Person Transactions Policy requires any Related Person Transaction to be promptly reported to the Chair of our Nominating and Corporate Governance Committee. In approving, ratifying or rejecting a Related Person Transaction, our Nominating and Corporate Governance Committee will consider such information as it deems important to determine if the Related Person Transaction is fair to our Company. Our Conflict of Interest Policy requires our employees and directors to report to our General Counsel any potential conflict of interest situation involving any employee or director, or their Immediate Family Members. During fiscal 2026, there were no Related Party Transactions involving a Related Person, as defined in the policy.

Insider Trading and Tipping and Hedging Policy

We have an Insider Trading and Tipping and Hedging Policy (“Insider Trading Policy”) that governs the purchase, sale, or other disposition of the Company's securities by our Company's directors, Section 16 officers, employees and related parties. Our Insider Trading Policy was reasonably designed to comply with applicable insider trading laws, rules and regulations, and listing requirements. Our Insider Trading Policy prohibits our Company's directors, Section 16 officers and employees from trading in the Company's securities while aware of material non-public information subject to certain exceptions, including pre-arranged trading programs pursuant to Rule 10b5-1 under the Securities Exchange Act of 1934. Directors and Section 16 officers are required to seek pre-clearance and approval of their transactions in the Company's securities by our General Counsel, and to comply with the Company's prescribed trading window. Our Insider Trading Policy also, among other things, prohibits tipping or disclosing material non-public information to others, and prohibits our Company's directors, Section 16 officers and employees from short selling, hedging and pledging the Company's stock. In addition, with regard to the Company's trading in its own securities, it is the Company's policy to comply with the federal securities laws and the applicable exchange listing requirements. A copy of our Insider Trading Policy can be found as Exhibit 19.1 to our most recent Annual Report on Form 10-K.

Non-Employee Director Compensation

Non-Employee Director Compensation Arrangements During Fiscal 2026

We structure director compensation to attract and retain qualified non-employee directors and to further align the interests of directors with the interests of our shareholders.

Our Board of Directors approves the compensation for members of our Board of Directors and Committees based on the recommendations of our Nominating and Corporate Governance Committee. We target compensation for service on our Board of Directors and Committees within a reasonable range around the 50th percentile for board service at companies in our peer group of companies, using the same peer group used for executive compensation purposes. Generally, our Nominating and Corporate Governance Committee reviews and discusses the compensation data and analysis provided by management with assistance from the Company's independent compensation consultant. Our Chief Executive Officer participates in the discussions on compensation for members of our Board of Directors. Directors who are employees receive no additional compensation for serving on our Board of Directors.

The following table describes the compensation arrangements with our non-employee directors as of the end of fiscal 2026.

Compensation						Fiscal 2026
Annual Cash Retainers:
Independent Chair of the Board						$135,000
Lead Director						30,000
Board Member						75,000
Audit Committee Chair						30,000
Audit Committee Member						15,000
Compensation Committee Chair						25,000
Compensation Committee Member						10,000
Nominating and Corporate Governance Committee Chair						25,000
Nominating and Corporate Governance Committee Member						10,000
Annual Equity Grant Board of Directors Chair						135,000			(1)
Annual Equity Grant						115,000			(1)
Charitable Matching Contributions Program						$2,000 maximum aggregate annual match

_________________

(1)On June 25, 2025, we granted a restricted stock award of 3,468 shares to Mr. Nolan, while he served as Independent Chair of our Board, having a value of approximately $135,000 on the date of grant, and restricted stock awards of 2,954 shares to each other non-employee director having a value of approximately $115,000 on the date of grant. The awards vest over three years in equal annual installments on the anniversaries of the grant date. See “Fiscal 2026 Non-Employee Director Compensation Table” beginning on page 31 for additional details.

Annual Equity Awards

Annual equity awards to non-employee directors, which may be restricted stock or restricted stock units, are issued pursuant to our 2019 Director Stock Plan. Each non-employee director receives a prorated award on or about the date they are first elected to our Board and annually on or about the date of our annual meeting of shareholders if their term continues after such meeting. The dollar value of the award is determined by our Board of Directors in June of each year, after recommendation by our Nominating and Corporate Governance Committee and in consideration of various factors, including market data and trends. We target the equity-based compensation received by non-employee directors at approximately the 50th percentile of our peer group of companies. Equity awards generally vest in equal annual installments over a three-year vesting period. Upon issuance of restricted stock, each holder is entitled to the rights of a shareholder, including the right to vote the shares of restricted stock. For restricted stock awards made pursuant to our 2019 Director Stock Plan,

29

dividends or other distributions (whether cash, stock or otherwise) will accrue during the vesting period and will be paid only upon vesting. Awards will be forfeited upon the termination of a director’s service, unless the director is terminated by the Company due to retirement, death or disability, in which case restricted stock will accelerate and vest. If a change in control (as defined in the 2019 Director Stock Plan) occurs, any award shall vest immediately.

Director Deferred Compensation Arrangements

Deferral of Equity Awards

In lieu of receiving a restricted stock award, non-employee directors have the option to receive a deferred restricted stock unit award, pursuant to the Restricted Stock Deferral Program adopted by our Board under our 2019 Director Stock Plan. By electing to receive a deferred restricted stock unit award, a director can defer receipt of all or a portion of any award. Each non-employee director who receives a deferred restricted stock unit award in lieu of an award receives a credit of shares of our common stock in an amount equal to the number of shares or units they would have received pursuant to the award. The account is also credited, as of the crediting date, with an amount equal to the dividend paid on one share of our common stock multiplied by the number of shares or units credited to each account. Non-employee directors receiving a deferred restricted stock unit award may elect to receive the amounts credited to their account at a fixed date, at age 70, or following death or retirement from our Board of Directors. The deferred restricted stock unit awards and related accumulated dividends are paid out in the form of shares of our common stock (plus cash in lieu of fractional shares) either in a lump sum or in installments, at the participating director’s election. This is an unfunded book-entry plan and no trust or other vehicle has been established to hold any shares of our common stock.

Deferral of Cash Retainers

Under our prior Deferred Compensation Plan for Non-Employee Directors, which was in effect through December 31, 2021, participants could elect to defer all or a portion of their annual cash retainer into deferred stock accounts. There was no Company match on amounts deferred by our non-employee directors under such plan. Each participating director received a credit of shares of our common stock in an amount equal to the amount of annual cash retainer deferred divided by the fair market value of one share of our common stock as of the crediting date. These accounts also were credited, as of the crediting date, with an amount equal to the dividend paid on one share of our common stock multiplied by the number of shares credited to each account. Participating directors may elect to receive the amounts credited to their accounts at a fixed date, at age 70, or following death or retirement from our Board of Directors. The deferred amounts are paid out in the form of shares of our common stock (plus cash in lieu of fractional shares) either in a lump sum or in installments, at the participating director’s election. This plan is an unfunded, book-entry, “phantom stock unit” plan, as no trust or other vehicle has been established to hold any shares of our common stock.

Effective as of January 1, 2022, non-employee directors could elect to defer all or a portion of their annual cash retainer into the 2021 Deferred Compensation Plan for Non-Employee Directors. Under this plan, we credit a participant’s plan account with earnings based on the participant’s investment allocation among a menu of hypothetical investment fund options. An Apogee common stock fund is not one of the investment options available under this plan. Participants may elect to receive the amounts credited to their accounts at a fixed date or following retirement from our Board of Directors. Like the prior plan, all amounts paid under this plan are paid from our general assets and are subject to the claims of our creditors. The material terms of this plan are otherwise comparable to those of the prior plan.

Charitable Matching Contributions Program for Non-Employee Directors

Under our Charitable Matching Contributions Program for Non-Employee Directors, we match cash or publicly traded stock contributions made by our non-employee directors to approved charitable organizations that are exempt from federal income tax up to a maximum aggregate amount of $2,000 per eligible non-employee director per calendar year.

Our Strategy. Throughout fiscal 2026, we executed the strategy introduced in November 2021, which strengthened our organization through the implementation of the Apogee Management System, drove improvements to our cost structure and manufacturing footprint, and increased leverage of administrative functions across the enterprise. This strategy also contributed to meaningful safety improvements and a more focused product and service portfolio, leading to margin and profitability improvement. Building on this foundation, we are refining our strategic framework to further enhance execution and position Apogee as a more growth-oriented organization with an increased focus on delivering customer value.

Our enhanced Company strategy is based on the following three key pillars:

1.Accelerate Leadership in Target Markets. We intend to enhance our position in targeted end markets by differentiating through deep customer focus and insight, using an informed understanding of customer needs to shape our offerings and delivery models. By aligning our capabilities, investments, and operating approach around this customer-focused strategy, we believe we will be better positioned to differentiate, compete effectively, and strengthen our position in the markets we serve.

2.Grow and Strengthen the Portfolio. We seek to grow and strengthen our portfolio through disciplined organic and inorganic investments in differentiated solutions that align with evolving customer needs. By prioritizing opportunities that enhance our competitive positioning and directly address customer challenges, we will reinforce our disciplined approach to portfolio growth and improvement.

35

3.Advance Core Capabilities. We expect to advance core capabilities by fostering a culture of continuous improvement grounded in operational excellence, talent development, and disciplined process execution. Through targeted investments in people, systems, and technology, we will strengthen our ability to deliver consistent performance and enhance the customer experience across the organization.

We continually analyze our current portfolio of products, services, and capabilities to identify the best areas for future profitable growth. We also evaluate inorganic investment opportunities where we can deploy capital to acquire businesses that will be accretive to our long-term growth rate and operating margins.

Use of Non-GAAP Financial Measures

The following measures are not calculated in accordance with generally accepted accounting principles ("GAAP"). These non-GAAP financial measures should be viewed in addition to, and not as an alternative to, the reported financial results of the Company in accordance with GAAP. Other companies may calculate these measures differently from us, thereby limiting the usefulness of the measures for comparison with others.

Adjusted EBITDA is a non-GAAP financial measure that we define as net earnings excluding interest expense, income tax expense, depreciation, amortization and certain non-GAAP adjustments. Segment Adjusted EBITDA includes net earnings related to intersegment sales transactions and other income and expense related to the segment and excludes certain corporate costs that are not allocated at a segment level. We believe these measures are useful in understanding operational profitability over time.

Adjusted diluted earnings per share ("Adjusted Diluted EPS") is a non-GAAP financial measure defined as diluted earnings per share excluding adjustments that management does not consider part of core operating results. We believe this measure is useful in understanding operational performance.

Adjusted return on invested capital ("Adjusted ROIC") is a non-GAAP financial measure defined as net earnings excluding interest expense, other income (expenses), and adjustments that management does not consider part of core operating results, all net of tax and divided by average invested capital. We believe this measure is useful in understanding operational performance.

Executive Compensation Philosophy and Practices. Our compensation programs are designed to attract, motivate and retain executive talent to achieve success in both the short-term and long-term for our Company; pay for sustainable performance in an ever-changing environment; and align the interests of our executive officers with our shareholders. We continue to refine our executive compensation program to reflect changes in our business strategy and evolving executive compensation practices.

Our Executive Compensation Practices: (What We Do)			Beginning on Page			Executive Compensation Practices We Have Not Implemented or Have Discontinued: (What We Don’t Do)			Beginning on Page
We seek alignment of pay and performance each year. A significant portion of our compensation program is performance-based through the use of our short-term and long-term incentive plans.			37			Other than an Offer Letter with Mr. Nolan (which expires October 31, 2026), entered into in connection with his election as Chief Executive Officer, and an Offer Letter with Mr. Augdahl, entered into in connection with his promotion to Executive Vice President and Chief Financial Officer, the Company has no employment contracts for our Named Executive Officers.			5 - 6
We review “tally sheets” and realizable pay and performance for our Named Executive Officers and use that information as a factor in making compensation decisions.			40			We generally do not pay short-term incentive compensation if our Company is not profitable for the year.			42
The Compensation Committee annually determines whether its compensation consulting firm fully meets the stringent independence requirements under the final rules of the Dodd-Frank Act.			40			We do not pay dividends during the restricted periods on unvested equity awards made pursuant to our 2019 Stock Incentive Plan.			46
We evaluate share utilization by annually reviewing overhang and burn rates.			41			We do not provide tax reimbursement or tax “gross-ups” on any perquisites.			50
We have adopted share ownership guidelines, and we review compliance annually.			51			We do not allow hedging or pledging of company shares.			51
We have clawback policies that comply with Nasdaq listing standards and go beyond that to cover a broader population of participants in our executive compensation program.			51			We do not believe any of our Company’s compensation programs create risks that are reasonably likely to have a material adverse effect on our Company.			52
We mitigate undue compensation risk by utilizing caps on potential payments, multiple financial performance metrics, and different metrics for our short-term cash incentives and long-term performance awards, as well as having robust Board and Board Committee processes to identify and manage risk.			52			We do not provide for excise tax “gross-ups” or “single triggers” in our change-in-control severance agreements.			64
We have change-in-control severance agreements with all of our Named Executive Officers that provide benefits only upon a “double trigger.”			63			We do not reprice underwater stock options or stock appreciation rights.

The Role of Shareholder Vote on Say on Pay Proposal. Our Company provides our shareholders with the opportunity to cast an advisory vote on our Say on Pay Proposal annually. At our Company’s 2025 Annual Meeting of Shareholders held on June 25, 2025, 91.92% of the votes cast on the Say on Pay Proposal were voted in favor of ratification of the proposal. The Committee did not make any changes to its programs in response to this vote. The Committee will consider the outcome of our Company’s Say on Pay Proposal when making future compensation decisions.

Determining Executive Compensation

Our executive compensation program is evaluated annually taking into consideration changes to our business strategy and annual operating plan, the economy and our competitive marketplace, a robust strategic goal setting process, and evolving executive compensation practices.

During the first quarter of each fiscal year, the performance of each of our Named Executive Officers is evaluated based on a subjective assessment of: (i) their executive leadership; (ii) enterprise competencies; and (iii) achievement of agreed-upon individual business objectives for the just-completed fiscal year. The annual performance evaluation of our Chief Executive Officer is administered by our Nominating and Corporate Governance Committee, with all non-employee directors participating in the performance evaluation, and the results of the Chief Executive Officer’s annual performance evaluation are reviewed by the Committee and our full Board. Our Chief Executive Officer conducts or participates in the annual performance evaluation of our Other Named Executive Officers and reviews the results with members of the Committee.

In establishing the elements and levels of compensation for a fiscal year, the Committee considers the annual performance evaluations of our Named Executive Officers and reviews its compensation consultant’s independent analyses of compensation based on comparable positions, using both published survey sources and company peer group data to determine our competitive positioning relative to the market. Our Chief Executive Officer makes recommendations to the Committee on compensation for our Other Named Executive Officers, but does not participate in the determination of his own compensation.

The Committee continuously monitors our compensation programs and annually reviews a compensation “tally sheet,” which lists total direct compensation (base salary, short-term cash incentive compensation, and long-term incentive awards), perquisites, other elements of executive compensation, broad-based employee benefits and wealth accumulation through our Company equity and retirement plans for our Named Executive Officers; however, the compensation tally sheets are not used to make actual pay decisions. The Committee assesses historical pay and performance to ensure continued alignment of our compensation programs.

Consulting Assistance, Peer Group and Competitive Market

Compensation Consultant Independence. The Compensation Committee has the authority to retain independent compensation consultants to provide counsel and advice regarding compensation levels for our executive officers and related matters. In October 2025, the Committee retained Meridian Compensation Partners, LLC ("Meridian") as its new independent compensation consultant. Willis Towers Watson (“WTW”), served as the Company's independent compensation consultant through September 2025. The compensation consultant reports directly to the Committee, and the Committee can replace the compensation consultant or hire additional consultants at any time. During fiscal 2026, WTW attended each Committee meeting during their tenure in person or by video conference, including executive sessions as requested, and consulted with the Chair of the Committee between meetings. Beginning in January 2026, Meridian attended each Committee meeting in person or by video conference, including executive sessions as requested, and consulted with the Chair of the Committee between meetings.

As required under the Dodd-Frank Act, the Committee has analyzed whether the work of WTW or Meridian, as its compensation consultants, raises any conflict of interest, taking into consideration the following factors under the Nasdaq listing rules: (i) neither WTW nor Meridian provides any other services to our Company, except that WTW provided brokerage services for the Company’s property insurance and surety bonds in exchange for fees less than $120,000 in fiscal 2026; (ii) the amount of fees from our Company paid to WTW and Meridian is less than 1% of each of WTW's and Meridian's total revenue; (iii) WTW and Meridian's policies and procedures are designed to ensure independence; (iv) neither WTW nor Meridian, nor any member of their respective consulting teams, has any business or personal relationship with any executive officer of our Company, and no member of their consulting team has any business or personal relationship with any member of the Committee; and (v) neither WTW nor Meridian, nor any member of their respective consulting team, owns any stock of our Company.

The Committee has determined, based on its analysis of the above factors, that WTW and Meridian are independent of our Company and the work of WTW and Meridian (and the individual compensation advisors employed by WTW and Meridian) as compensation consultants to the Committee, and the additional services

40

provided by WTW and Meridian, have not created a conflict of interest. The Committee will continue to annually monitor the independence of its compensation consultant.

Peer Group. The selection criteria identified for determining and reviewing our Company’s peer group generally include:

•Companies with revenue within a similar range (0.33 to 3.0 multiple).

•Companies with market capitalization within a similar range (0.33 to 3.0 multiple).

•Companies with market capitalization to revenue ratio of 0.5 or greater.

•Companies in the same or similar industries.

•Companies with business model similarity, which may include the following:

–Coatings for special purposes;

–Construction materials, primarily for commercial or industrial applications;

–Specialized/customized product lines;

–Heavy-duty manufacturing operations and project-directed manufacturing; and

–Project-based businesses.

•Companies in the same geographic location (to a lesser degree).

•Companies included in the prior-year peer group, to help ensure year-over-year consistency (where appropriate).

The following 16 firms served as the Company’s peer group for fiscal 2026.

•American Woodmark Corporation			•H.B. Fuller Company
•Armstrong World Industries, Inc.			•Insteel Industries, Inc.
•AZZ Inc.			•Janus International Group, Inc.
•Eagle Materials Inc.			•Quaker Chemical Corporation
•EnPro Inc.			•Quanex Building Products Corporation
•Gibraltar Industries, Inc.			•Simpson Manufacturing Co., Inc.
•Graco Inc.			•Tennant Company
•Griffon Corporation			•Trex Company, Inc.

The Company added Janus International Group, Inc., Simpson Manufacturing Co., Inc. and Trex Company, Inc., and removed Masonite International Corporation and PGT Innovations, Inc.

Competitive Market. The Committee relies on its independent compensation consultant to help define the appropriate competitive market using a combination of the peer group companies and compensation surveys that contain market compensation information for similarly-sized organizations. The information on the competitive market is used by the Committee:

•As an input in designing our compensation plans and philosophy;

•As an input in assessing and developing base salary adjustments, short-term cash incentive targets and long-term incentive ranges;

•To benchmark the form and mix of long-term incentive awards;

•To assess the competitiveness of total direct compensation awarded to our Named Executive Officers and certain of our other executives; and

•To benchmark dilution and overhang levels (dilutive impact on our shareholders of equity compensation) and annual burn rate (the aggregate shares awarded as a percentage of total outstanding shares).

41

Fiscal 2026 Individual Compensation Actions

Base Salary. Base salary reflects a fixed portion of the overall compensation package and is the base amount from which certain other compensation elements are determined. In making salary adjustments, the Committee considers the executive’s base salary relative to the market, our compensation philosophy and other factors, such as individual performance against business plans, leadership, initiatives, experience, knowledge and job criticality. For fiscal 2026, Mr. Nolan's base salary was established in the CEO Offer Letter, and Ms. Lakkundi did not receive a base salary increase, because she was hired in January 2025. The returning Named Executive Officers received base salary increases ranging from 1.76% to 4.02% except for Mr. T. Johnson who received an 18.00% increase for his reassignment to the position of President, Architectural Metals Segment, effective August 7, 2025.

Below is information on the base salaries of our Named Executive Officers for fiscal 2026.

Base Salary
Name						Fiscal 2026 Base Salary ($)									Percent Increase in Fiscal 2026 vs 2025 (%)
Donald A. Nolan(1)						925,000									—
Mark R. Augdahl(2)						550,000									—
Troy R. Johnson						505,050									18.00

Brent C. Jewell						463,000									1.76
Ty R. Silberhorn(3)						932,000									—
Matthew J. Osberg(4)						672,000									4.02

___________________________

(1)Mr. Nolan was appointed as our Chief Executive Officer and Executive Chair of the Board of Directors at the close of business on October 31, 2025, during fiscal 2026. His fiscal 2026 base salary, as presented above, became effective on that date.

(2)Mr. Augdahl was elected as Executive Vice President and Chief Financial Officer on January 19, 2026. His fiscal 2026 base salary, as presented above, became effective on that date and reflects an adjustment to keep it market competitive with comparable roles within the compensation peer group.

(3)Mr. Silberhorn separated from the Company on October 31, 2025, during fiscal 2026.

(4)Mr. Osberg resigned from the Company effective January 16, 2026, during fiscal 2026.

Short-Term Cash Incentive Compensation. Short-term cash incentive awards create an incentive for achievement of annual financial performance results. These results are measured against objective financial goals based on the annual operating plan approved by our Board of Directors.

The awards may be earned below or above target based on the achievement of one or more additional predetermined, objective performance goals based on the annual operating plan approved by our Board of Directors. At least one of the predetermined, objective performance goals must be met at the threshold level in order for any short-term cash incentive to be paid to an executive.

Generally, if actual results are below threshold performance level for all performance goals or the Company is not profitable, the payout will be zero. If the threshold performance level for one or more, but not all, performance goals is achieved, less than 50% of the target award will be earned based on the weighting allocated to that specific performance goal. If the threshold performance level for all performance goals is achieved, 50% of the target award will be earned; if target performance level for all performance goals is achieved, 100% of the target award will be earned; and if maximum performance level for all performance goals is achieved, 200% of the target award will be earned. For any performance between these levels, award payouts will be interpolated.

Nolan Short-Term Cash Incentive Plan. The Board approved four equally weighted objectives for Mr. Nolan's short-term cash incentive plan, which will be paid out on the earlier of the appointment of a successor CEO or October 31, 2026, the end of the Term for the CEO Offer Letter. In sum, the objectives include:

•Engagement with the Board and Executive Committee to set a new vision, strategy and financial targets for the Company;

•Growth: Establish a framework for customer focus to accelerate near term organic growth. Grow faster than the market, utilizing FMI benchmark for Architectural Segments, and 7% for Performance Surfaces;

•People: Fill key positions and work with the Board to evaluate potential internal candidates for CEO; and

•Strengthen the Core: Drive alignment and efficiency with corporate functions to deliver cost savings.

Like the short-term incentive plan for the Other Named Executive Officers, the target payout is equal to 100% of base salary actually paid during the Term, with an actual award between 0% to 200% of base salary. The actual award is subject to Board or Compensation Committee discretion.

Long-Term Incentive Compensation. Our long-term incentive program is designed to align the interests of executives with shareholders and to focus executives on the achievement of long-term sustained performance, entrepreneurship, and delivery of quality products and services, while creating appropriate retention incentives through the use of multi-year vesting schedules.

In fiscal 2026, our long-term incentive program for our Named Executive Officers (other than Mr. Silberhorn, our former Chief Executive Officer and Mr. Nolan, our current Chief Executive Officer) was comprised of 50% time-based restricted stock awards and 50% performance awards with a three-year performance period, each described in more detail below. Mr. Silberhorn’s, our former Chief Executive Officer, long-term incentive award in fiscal 2026 consisted of 40% time-based restricted stock and 60% as a performance award, of which 100% vesting on the time-based restricted stock accelerated at his time of separation, and the performance award was forfeited. Mr. Nolan received a Service Award pursuant to the CEO Offer Letter, and he did not participate in our long-term incentive program in fiscal 2026.

Dividends or other distributions (whether cash, stock or otherwise) with respect to the awards will accrue during the three-year vesting or other performance period and will be paid only on the shares earned at the end of the period when shares are issued.

Restricted Stock Awards. Each year, the Compensation Committee approves a time-based restricted stock award for each executive with a preliminary target fixed dollar value based on a percentage of base salary, after reviewing long-term incentives for comparable roles at peer companies, and based on data provided by the independent compensation consultant. For our Chief Executive Officer, the Committee determines the award’s value after considering the results of our Chief Executive Officer’s most recent annual performance evaluation. For our Other Named Executive Officers, our Chief Executive Officer recommends to the Committee increases or decreases in the award’s value based on the executive’s contributions to the Company’s performance, future leadership potential, and subjective evaluation of their individual performance for the just completed fiscal year.

Restricted stock awards are granted under the 2019 Stock Incentive Plan, and they generally vest in three equal annual installments commencing on April 30 of the year following the date of the award. Upon issuance of the restricted stock, each holder is entitled to the rights of a shareholder, including the right to vote the shares of restricted stock. Restricted stock awards issued pursuant to the 2019 Stock Incentive Plan accrue dividends during the vesting period and be paid only if the restricted stock vests. The following table summarizes the restricted stock awards granted to each of the Named Executive Officers in fiscal 2026.

(1)The value of the award was calculated by multiplying the number of shares of restricted stock awarded by the closing price of our common stock on the Nasdaq Global Select Market on the date of grant. The annual long-term incentive awards were made on April 22, 2025, for the Named Executive Officers.

(2)Mr. Nolan was appointed Chief Executive Officer of the Company effective as of the close of business on October 31, 2025, during fiscal 2026. The CEO Offer Letter provided for the grant to Mr. Nolan of a Service Award of 49,240 time-based restricted shares of the Company's stock valued at $1,749,990, based on the closing price on January 14, 2026. The Service Award is subject to Mr. Nolan's continued employment with the Company for the Term of the CEO Offer Letter, provided that Mr. Nolan's employment ends before the vesting date, the shares will vest as long as Mr. Nolan remains a member of the Board through the vesting date. The CEO Offer Letter further provides that the Service Award is subject to forfeiture upon voluntary or involuntary termination for cause, as defined in the Company's current standard form of restricted stock award agreement. Based on Mr. Nolan's election, 41,854 were granted as deferred restricted stock units and 7,386 were granted as an unvested restricted stock award.

(3)In addition to his annual long-term incentive award described in footnote (1), in connection with the promotion of Mr. Augdahl to Executive Vice President and Chief Financial Officer, effective as of January 19, 2026, the Company granted him 18,960 restricted shares with a grant date fair value of $700,003. Assuming continued employment with the Company, 50% of the restricted shares will vest on each of the first and second anniversaries of Mr. Augdahl's promotion. If Mr. Augdahl's employment is terminated due to retirement or involuntary termination without cause prior to one year of service, Mr. Augdahl will be eligible to receive 50% of the initial grant immediately and the remainder will be forfeited. Between one year and two years of service, if Mr. Augdahl's employment is terminated due to retirement or involuntary termination, Mr. Augdahl will be eligible to receive the remainder of the award immediately;

(4)In addition to his annual long-term incentive award described in footnote (1), in connection with the reassignment of Mr. T. Johnson to President, Architectural Metals Segment, effective August 7, 2025, the Company granted him 8,553 restricted shares effective October 17, 2025 with a grant date fair value of $325,014. Assuming continued employment with the Company 100% of the restricted shares will vest on the two-year anniversary of Mr. T. Johnson's appointment. The Company also granted him 16,882 restricted shares effective January 14, 2026 with a grant date fair value of $599,986. The Committee approved this award to support retention and leadership continuity during a period of executive transition. In making this award, the Committee considered the importance of retaining key segment leaders and the level of unvested and at-risk long-term incentive compensation outstanding. Assuming continued employment with the Company, 50% of the restricted shares will vest on each of the first and second anniversaries of the grant date.

(5)In addition to her annual long-term incentive award described in footnote (1), the Company granted Ms. Lakkundi a retention award of 16,882 restricted shares effective January 14, 2026 with a grant date fair value of $599,986. The Committee approved this award to support retention and leadership continuity during a period of executive transition. In making this award, the Committee considered the importance of retaining key segment leaders and the level of unvested and at-risk long-term incentive

compensation outstanding. Assuming continued employment with the Company, 50% of the restricted shares will vest on each of the first and second anniversaries of the grant date.

(6)In addition to his annual long-term incentive award described in footnote (1), the Company granted Mr. Jewell retention award of 16,882 restricted shares effective January 14, 2026 with a grant date fair value of $599,986. The Committee approved this award to support retention and leadership continuity during a period of executive transition. In making this award, the Committee considered the importance of retaining key segment leaders and the level of unvested and at-risk long-term incentive compensation outstanding. Assuming continued employment with the Company, 50% of the restricted shares will vest on each of the first and second anniversaries of the grant date.

(7)Mr. Silberhorn separated from the Company on October 31, 2025, during fiscal 2026, and vesting on these restricted shares was accelerated.

(8)Mr. Osberg resigned from the Company effective January 16, 2026, during fiscal 2026, and he forfeited the restricted shares.

Performance Awards. The Compensation Committee issues performance awards annually, with an overlapping three-year performance period beginning with each fiscal year's award. The Committee adopted the three-year performance award to better align the Company's long-term incentive plan with market practice and the Company's strategic plan and financial performance goals.

In fiscal 2026, the Committee awarded performance awards with a three-year performance period of fiscal 2026 – 2028 to the Named Executive Officers. All performance awards were granted under the 2019 Stock Incentive Plan. The performance metrics for the awards are three-year cumulative Adjusted Diluted EPS weighted at 60%, with a target three-year cumulative Adjusted Diluted EPS of $15.76, and average Adjusted ROIC over the three-year performance period weighted at 40%, with a target average Adjusted ROIC of 12.87%. The threshold payout is 20% of target, and the maximum payout is 200% of target. The performance awards will settle 50% in cash and 50% in stock. The following table sets forth payout ranges as a percentage of salary at target performance with respect to our fiscal 2026 – 2028 performance awards.

Fiscal 2024 – 2026 Performance Award Payouts. Performance awards having a three-year performance period through the end of fiscal 2026 were settled 50% in shares and 50% in cash. The performance metric for the awards was average Adjusted ROIC over the three-year performance period, with a target average Adjusted ROIC of 14.64%. The following table outlines the threshold, target and maximum for these performance awards, as well as actual performance and the percentage of the performance awards achieved.

Fiscal 2024 – 2026 Performance Goals
Performance Metric						Weight (%)						Threshold (50%)						Target (100%)						Maximum (200%)						Actual Performance (%)						Percentage Performance Achieved (%)
Average Adjusted ROIC						100.00						12.00						14.64						15.50						13.78						83.71

Other Benefit Programs. Our executive officers receive the same health and welfare benefits as those offered to all other full-time employees, with the exception of enhanced long-term disability benefits being offered to our executive officers.

We have entered into change-in-control severance agreements with each of our Named Executive Officers. See “Change-in-Control Severance Agreements” beginning on page 63 and “Payments Upon Termination or Change-in-Control” beginning on page 62 for more information on these arrangements.

In order to maintain market-competitive benefits and to encourage our Named Executive Officers to focus on their roles at the Company, we provide a limited number of perquisites, including the reimbursement of financial and estate planning fees of up to $2,000 annually, enhanced long-term disability benefits, payment of relocation expenses, reimbursement of annual executive health physical costs up to $3,000 annually and reimbursement of spousal travel expenses for certain Company events. We do not provide tax reimbursement or tax “gross-ups” on any perquisites.

Executive Stock Ownership Guidelines

We have stock ownership guidelines for our executive officers that require our Chief Executive Officer to achieve an ownership level of five times their annual base salary; our Chief Financial Officer to achieve an ownership level of three times their annual base salary; certain corporate officers and segment presidents, including Messrs. T. Johnson, Jewell and Ms. Lakkundi, to achieve an ownership level of two times their annual base salaries; and other corporate officers to achieve an ownership level of one time their annual base salary. The Compensation Committee monitors compliance with our stock ownership guidelines on a regular basis. Each executive has five years from the date they become subject to the stock ownership guidelines to meet their ownership guideline. If an executive is promoted and the target is increased, an additional three-year period is provided to meet the ownership guideline. For purposes of calculating stock ownership, we include unvested shares of restricted stock.

As of April 27, 2026, all of our active Named Executive Officers are either in compliance with the stock ownership guidelines or still within the applicable grace period for achieving these ownership levels.

Anti-Hedging and Anti-Pledging Policies

Our Board of Directors believes that the interests of our executive officers, employees and members of our Board of Directors should be aligned with the interests of our shareholders. As a result, we have adopted an anti-hedging policy that prohibits all employees and members of our Board of Directors from engaging in the purchase or sale of financial instruments (including prepaid variable forward contracts, equity swaps, collars and exchange funds) that are designed to hedge or offset any decrease in the market value of our Company’s securities. Our Board of Directors has also adopted an anti-pledging policy, which states that executive officers and directors of the Company are prohibited from, directly or indirectly, pledging, hypothecating, or otherwise encumbering shares of the Company’s common stock as collateral for indebtedness. This prohibition includes, but is not limited to, holding such shares in a margin account or any other account that could cause the Company’s common stock to be subject to a margin call or otherwise be available as collateral for a margin loan. None of our Named Executive Officers have pledged shares of our common stock as collateral for personal loans or other obligations.

Clawback Policy

In October 2023, our Board of Directors adopted an incentive compensation recovery policy providing for the recovery of erroneously awarded incentive compensation in the event that the Company is required to prepare an accounting restatement due to material noncompliance of the Company with any financial reporting requirements under the federal securities laws and to comply with Section 10D of the Securities Exchange Act of 1934, as amended. This policy is available as Exhibit 97.1 to the Company's most recent Annual Report on Form 10-K. The Company has also adopted a similar policy for other participants of the executive compensation program. Both policies apply to incentive compensation (as defined in the policies) awarded on or after October 2, 2023. Incentive compensation received by executives before October 2, 2023 remains subject to the Company’s prior Clawback Policy dated April 30, 2014, as amended.

Policy and Procedures for the Granting of Equity-Based Awards

We currently do not grant stock options. Grants of other equity-based awards to employees, including long-term incentive awards, are generally approved on a regular schedule. However, grants to new hires or for promotions, retention, or purposes other than annual or other broad-based Company-wide grants may be approved outside of regularly scheduled meetings. In those circumstances, the grant date is the date the award is approved, or if the approval date is within a blackout period, the fifth business day following the date on which the Company first releases quarterly earnings following the effective date of the recipient's employment, promotion or recognition, as applicable.

The Company will not purposely accelerate or delay the public release of material information in consideration of a pending equity-based award in order to allow an award recipient to benefit from a more favorable stock price.

51

The Company recognizes, however, that a release of information by the Company in close proximity to an equity-based award could create the appearance of an effort to time the announcement to a recipient's benefit, even if no such benefit was intended. Accordingly, management will advise the Compensation Committee whenever it is aware that material non-public information is planned to be released to the public in close proximity to the grant of an equity-based award. The Committee will consider such information and determine whether to delay the equity-based award to avoid any appearance of impropriety. During fiscal 2026, we did not time the disclosure of material non-public information for the purpose of affecting the value of executive compensation.

Tax Considerations

Section 162(m) of the U.S. Internal Revenue Code ("Section 162(m)") imposes a $1,000,000 annual deduction limit on compensation payable to certain current and former named executive officers. The Compensation Committee intends to pay competitive compensation consistent with our philosophy to attract, retain and motivate executive officers to manage our business in the best interests of the Company and our shareholders. The Committee, therefore, may choose to provide non-deductible compensation to our executive officers if it deems such compensation to be in the best interests of the Company and our shareholders.

Various programs, including our benefit plans that provide for deferrals of compensation are subject to Section 409A of the Internal Revenue Code. We have reviewed such plans for compliance with Section 409A and believe that they comply.

Compensation Risk Analysis

During fiscal 2026 the Compensation Committee, with the assistance of its independent compensation consultant(s) and management, assessed risk in our compensation plans, practices and policies and determined that the Company’s compensation practices and policies do not create risks that are reasonably likely to have a material adverse effect on the Company. In performing this risk assessment, the Committee considered:

•The mix of fixed and variable compensation;

•The mix of short-term and long-term incentive compensation;

•The extent to which performance metrics are directly reflected in our audited financial statements or other objective reports;

•The relative weighting of the performance metrics;

•The likelihood that achievement of performance metrics could have a material impact on our financial performance in succeeding fiscal periods;

•The various compensation risk control mitigation features in our compensation plans, including balanced financial performance metrics that include net sales, earnings and operational metrics;

•Multiple financial performance metrics for our short-term cash incentive and long-term performance-based incentive plans;

•Different financial performance metrics for our short-term cash incentive and long-term performance-based incentive plans;

•Appropriate maximum caps on our short-term cash incentive and long-term performance-based incentive plans and annual equity awards;

•Management stock ownership guidelines; and

•Our clawback and hedging policies.

Non-Qualified Deferred Compensation

Deferred Compensation Plan

Our Deferred Compensation Plan is a non-qualified deferred compensation plan for a select group of management and other highly compensated employees of our Company and our subsidiaries, including our Named Executive Officers. For the 2025, 2024 and 2023 calendar years, approximately 137, 136 and 145 of our employees, respectively, were eligible to participate in our Deferred Compensation Plan and approximately 138 employees are eligible for the 2026 calendar year. Our Deferred Compensation Plan allows for deferrals by participants of up to 75% of base salary and sales commissions, and up to 100% of bonuses and other cash or equity-based compensation approved by the Compensation Committee, and also provides that we may establish rules permitting a participant to defer performance-based compensation up to six months prior to the end of a performance period. There is no maximum dollar limit on the amount that may be deferred by a participant each year. A participant in our Deferred Compensation Plan may elect to have the participant's account credited with earnings and investment gains and losses by assuming that deferred amounts were invested in one or more of 18 hypothetical investment fund options selected by the participant, which had investment returns ranging from 3.11% to 41.04% for calendar year 2025. An Apogee common stock fund is not one of the investment options available under our Deferred Compensation Plan. Participants are permitted to change their investment elections at any time. We may also make discretionary contributions to a participant's account under our Deferred Compensation Plan, and our Company will designate a vesting schedule for each such contribution. The participants are always 100% vested in the amount they defer, and the earnings, gains and losses credited to their accounts. Participants are entitled to receive a distribution from their account upon:

60

a separation from service, a specified date, death, disability, retirement (as defined in our Deferred Compensation Plan), or unforeseeable emergency that results in "severe financial hardship" that is consistent with the meaning of such term under Section 409A of the Internal Revenue Code. Distributions are in a lump sum, installments or a combination of lump sum with installments based upon the participant's election as allowed under our Deferred Compensation Plan. Our Deferred Compensation Plan is an unfunded obligation of Apogee, and participants are unsecured creditors of Apogee.

Legacy Deferred Compensation Plan

Our Deferred Incentive Compensation Plan (the "Legacy Deferred Compensation Plan") is a non-qualified deferred compensation plan for a select group of management and other highly compensated employees of our Company and our subsidiaries; however, in October 2010, the plan was amended to prohibit any future participant deferrals to the plan after our fiscal 2011. Our Legacy Deferred Compensation Plan allowed for deferrals by participants of up to 100% of bonuses. A participant in our Legacy Deferred Compensation Plan may elect to have the participant's account credited with the applicable interest rate as set forth in the plan or credited with earnings and investment gains and losses by assuming the deferred amounts were invested in one or more of 18 hypothetical investment fund options selected by the participant, which had investment returns ranging from 3.11% to 41.04% for calendar year 2025. Participants are permitted to change their investment elections at any time. For amounts deferred for plan years beginning on or after January 1, 2010, the applicable interest rate, which is not considered to be an “above-market” interest rate, is the monthly average yield for the last calendar month of the prior fiscal year on U.S. Treasury securities adjusted to a constant maturity of 10 years. For amounts deferred for plan years beginning prior to January 1, 2010, the applicable interest rate, which may be considered to be an “above-market” interest rate, is the greater of the following rates: (i) the sum of one and one-half percent (1- 1/2%) plus the monthly average yield for the last calendar month of the prior fiscal year on U.S. Treasury securities adjusted to a constant maturity of 10 years; or (ii) one-half of the rate of Apogee's after-tax return on beginning shareholders' equity for the prior fiscal year. Participants are entitled to receive a distribution from their account upon termination of employment (as defined in our Legacy Deferred Compensation Plan), disability, death, retirement (as defined in our Legacy Deferred Compensation Plan), or unforeseeable emergency that results in “severe financial hardship” that is consistent with the meaning of such term under Section 409A of the Internal Revenue Code. Distributions are in either a lump sum or installments based on participant elections as allowed under our Legacy Deferred Compensation Plan. Our Legacy Deferred Compensation Plan is an unfunded obligation of Apogee, and participants are unsecured creditors of Apogee.

___________________________

(1)Pursuant to SEC rules, all earnings in non-qualified deferred compensation in fiscal 2026 in excess of 5.79%, 120% of the applicable federal rate compounded annually, have been deemed "above-market earnings." During fiscal 2026, the interest paid on amounts deferred for plan years beginning prior to January 2010 pursuant to our Legacy Deferred Compensation Plan was 9.03%. This amount is reported in the "Change in Pension Value and Non-Qualified Deferred Compensation Earnings" column of the "Summary Compensation Table" beginning on page 53.

(2)The amount reported for Mr. Augdahl is reported in the "Summary Compensation Table" beginning on page 53 for fiscal 2026 in the "Non-Equity Incentive Plan Compensation" column. The amount reported for Mr. Augdahl for our Legacy Deferred Compensation Plan is not reported in the "Summary Compensation Table" on page 53, because all of these amounts were earned by him prior to fiscal 2026.

Potential Payments Upon Termination or Following a Change-in-Control

Except as discussed below, if the employment of any of our Named Executive Officers is voluntarily or involuntarily terminated, no additional payments or benefits will accrue or be owed to them.

Except as discussed below, or in connection with a change-in-control, a voluntary or involuntary termination will not trigger an acceleration of the vesting of any outstanding equity awards, subject to the Compensation Committee’s discretion to accelerate the awards.

62

Retirement

In the event a Named Executive Officer retires, the Compensation Committee may exercise its discretion to accelerate the vesting of their restricted stock awards. In the event a Named Executive Officer retires prior to the end of a performance period for a performance award, the Named Executive Officer will be entitled to receive a pro-rata payment (based on the amount of time elapsed between the beginning of the performance period and the date of termination) after the end of the performance period based on the level of achievement of the performance metric. In the event a Named Executive Officer retires after the performance period, they will be entitled to receive, if not yet paid, the performance award. None of our Named Executive Officers were deemed retirement eligible as of the end of fiscal 2026.

Payments Made Upon Termination Without Cause or For Good Reason

In connection with Mr. Silberhorn's appointment as Chief Executive Officer effective January 4, 2021, to replace forfeited compensation earned by him at his previous employer, he received restricted stock of the Company valued at $1,400,000, which vests in two installments over a five-year period, with the first installment of $500,000 vesting on January 4, 2023, and the second installment of $900,000 vesting on January 4, 2026 (the “Retention Grant Agreement”). If Mr. Silberhorn's employment is terminated within five years of the Commencement Date (as defined in the Retention Grant Agreement) by the Company without “Cause” (as defined in the Retention Grant Agreement) or by him for “Good Reason” (as defined in the Retention Grant Agreement), Mr. Silberhorn shall be entitled to automatic acceleration of any unvested shares of the Retention Grant Agreement. The second installment of unvested shares were accelerated and vested as of Mr. Silberhorn's departure on October 31, 2025.

Payments Made Upon Disability

Under the terms of the Apogee Enterprises, Inc. Short-Term and Long-Term Disability Plans, each of our Named Executive Officers who participates in such plans is eligible for a disability benefit. All Named Executive Officers are eligible for and have elected to participate in our enhanced Long-Term Disability Plan, and are eligible for a disability benefit that is equal to 100% of their monthly base salary during the first three months of disability and 60% of their monthly base salary up to a maximum of $15,000 per month thereafter.

If the employment of any of our Named Executive Officers is terminated due to disability, the terms of our restricted stock agreements provide for the immediate vesting of such awards. In the event employment is terminated prior to the end of a performance period for a performance award, the Named Executive Officer will be entitled to receive a pro-rata payment (based on the amount of time elapsed between the beginning of the performance period and the date of termination) after the end of the performance period based on the level of achievement of the performance metric. In the event employment is terminated after the performance period, the Named Executive Officer will be entitled to receive, if not yet paid, the performance award.

Payments Made Upon Death

The terms of our restricted stock agreements provide for the immediate vesting of such awards in the event of the Named Executive Officer’s death.

In the event of death prior to the end of a performance period for a performance award, the Named Executive Officer’s estate will be entitled to receive a pro-rata payment (based on the amount of time elapsed between the beginning of the performance period and the date of death) after the end of the performance period based on the level of achievement of the performance metric. In the event of death after the performance period, the Named Executive Officer’s estate will be entitled to receive, if not yet paid, the performance award.

Change-in-Control Severance Agreements

The Compensation Committee believes that offering a change-in-control program provides executive officers a degree of security in the event of a corporate transaction and allows for better alignment of executive officer and shareholder interests. We have entered into a change-in-control severance agreement (the “CIC Severance Agreement”) with each of our Named Executive Officers. Our CIC Severance Agreement is designed to retain

63

our executive officers and provide for continuity of management in the event of an actual or threatened “Change-in-Control of Apogee” (as defined in the CIC Severance Agreement).

Our CIC Severance Agreement contains a “double trigger” for benefits, which means that there must be both a “Change-in-Control of Apogee” and a qualifying termination of the executive’s employment for the provisions to apply. It provides that, in the event of a “Change-in-Control of Apogee,” each of our Named Executive Officers will have specific rights and receive specified benefits if the executive officer is terminated without “Cause” (as defined in the CIC Severance Agreement) or the executive officer voluntarily terminates their employment for “Good Reason” (as defined in the CIC Severance Agreement) within two-years after the “Change-in-Control of Apogee.” In these circumstances, our Named Executive Officers will each receive a severance payment equal to two times their annual base salary and short-term cash incentive at target level performance for such fiscal year. For Messrs. Augdahl, T. Johnson and Jewell and Ms. Lakkundi, our CIC Severance Agreement provides that, for a 24-month period following a “Change-in-Control of Apogee,” our Company will continue to provide medical and dental insurance coverage for the executive officer and the executive officer’s dependents or will reimburse the executive officer for the cost of obtaining substantially similar benefits. For Messrs. Silberhorn and Osberg, the CIC Severance Agreements that had been in place were no longer in effect following separation from the Company. No benefits will be paid to the executive officer pursuant to the CIC Severance Agreement unless the executive officer executes and delivers to Apogee a release of claims. Subject to the double trigger described above, all shares of restricted stock that have not vested by the Employment Termination Date will vest. For performance awards, the performance period will end on the date of the "Change-in-Control of Apogee," and the award will be adjusted by the Compensation Committee in its sole discretion. If a "Change-in-Control of Apogee" occurs after the performance period, the Company will pay any unpaid amount earned during the performance period.

We do not provide a tax gross-up payment for any excise tax liability under Internal Revenue Code Section 4999 related to Section 280G excess parachute payments.

Our CIC Severance Agreements contain a “best-net-benefit” provision which provides that, in the event that payments under the CIC Severance Agreements trigger excise tax for the Named Executive Officer, such officer has the option of either reducing the severance payment, if the net benefit is greater than paying the excise tax, or paying the excise tax themselves.

To receive these severance benefits, the executive officer shall not: (1) solicit, directly or indirectly, any of our existing or prospective customers, vendors or suppliers for a purpose competitive to our business or to encourage such customers, vendors or suppliers to terminate business with us; (2) solicit, directly or indirectly, any of our employees to terminate their employment; or (3) engage in or carry on, directly or indirectly, in certain geographic markets a business competitive with our business, for a period of 12- or 24-months following termination of employment.

The CIC Severance Agreements continue through December 31 of each year and provide for automatic extension for one-year terms prior to a "Change-in-Control of Apogee" unless we give prior notice of termination.

Payments Upon Termination or Change-in-Control

The table below shows potential payments to our Named Executive Officers upon certain terminations pursuant to disability, death or a change-in-control of our Company. The table below assumes that disability, death or the termination of employment occurred, or the "Change-in-Control of Apogee" was effective as of February 27, 2026, the last trading day of fiscal 2026. The amounts shown are estimates of the amounts that would be paid to the Named Executive Officers upon termination of employment or the change-in-control, in addition to the base salary and bonus earned by our Named Executive Officers for fiscal 2026. The actual amounts to be paid can only be determined at the actual time of a Named Executive Officer’s termination of employment.

___________________________

(1)Mr. Nolan became a Named Executive Officer as of the closed of business on October 31, 2025, during fiscal 2026.

(2)Includes restricted stock awards, which would vest upon an assumed occurrence on February 27, 2026, of one of the specified events. The amount in this table represents such aggregate number of shares multiplied by $39.82, the closing price of our common stock on the Nasdaq Global Select Market on February 27, 2026, the last trading day of fiscal 2026.

(3)This amount represents the annual disability payments during the first year of disability. Annual disability payments after the first year of disability would be $180,000 for each Named Executive Officer.

(4)Equals the sum of (a) two times their annual base salary as of February 28, 2026, and (b) two times their fiscal 2026 short-term cash incentive award at target level performance, payable in a lump sum.

(5)The Company will pay legal fees and expenses incurred to obtain or enforce any right or benefit under their CIC Severance Agreement.

(6)In the event employment is terminated due to retirement, disability or death prior to the end of the performance period for the performance awards, our Named Executive Officer, or their estate, will be entitled to retain and receive a pro-rata portion of the performance awards at the end of the performance period, to the extent earned.

(7)This amount represents the payout of performance cash, and performance share units at the target level and multiplied by $39.82, the closing price of our common stock on the Nasdaq Global Select Market on February 27, 2026, the last trading day of fiscal 2026, assuming the performance period ended on the date of the Change-in-Control of Apogee, as adjusted for the truncated performance period.

Silberhorn Separation Agreement

In connection with his separation effective on October 31, 2025 (the “Separation Date”), Mr. Silberhorn and the Company entered into a Separation Agreement dated October 30, 2025 (the “Separation Agreement”).

Upon Mr. Silberhorn’s separation as Chief Executive Officer of the Company, Mr. Silberhorn became entitled to $932,000 in cash, which is equal to his annual base salary for fiscal 2026. This payment will be made in twenty-four relatively equal payments on the Company’s regular payroll dates. As a material inducement for Apogee to enter into this Separation Agreement, Mr. Silberhorn must comply with certain non-recruitment covenants contained in the Separation Agreement.

Effective as of the Separation Date and pursuant to the terms of the relevant plans and award agreements, the Board accelerated the vesting of a total of 78,376 restricted shares, 16,867 performance share units, $742,500

66

performance cash, and $250,057 accrued dividends. The value of the accelerated restricted shares and performance share units was $3,486,846 based on the closing price of $36.61 on October 31, 2025.

The Company will pay $19,560, which represents the cost of Mr. Silberhorn's group medical, dental, and vision insurance, for twelve months after the Separation Date, provided that Mr. Silberhorn completes and returns the necessary paperwork to continue that coverage.

All cash paid or accrued in connection with Mr. Silberhorn's separation has been included in 2026 "All Other Compensation" in the "Summary Compensation Table" beginning on page 53. The value of the accelerated restricted shares and performance share units is not included.

Osberg Resignation

Mr. Osberg did not receive any payments upon his resignation beyond compensation and benefits earned during his employment with the Company.

CEO Pay Ratio Disclosure

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, we are providing the following information about the relationship of the annual total compensation of our employees and the annualized total compensation of Mr. Nolan, our Chief Executive Officer and Executive Director who was serving as of December 31, 2025 (the determination date for our median employees):

For the fiscal year ended February 28, 2026, our last completed fiscal year:

•the median of the annual total compensation of all employees of our Company (other than our Chief Executive Officer) was $67,025; and

•the annualized total compensation of our Chief Executive Officer, as reported in the “Summary Compensation Table” beginning on page 53 of this Proxy Statement, was $6,509,647.

We reasonably estimate that the ratio of our Chief Executive Officer’s annual total compensation to the annual total compensation of our median employee was 97 times. Our pay ratio estimate has been calculated in a manner consistent with Item 402(u) of Regulation S-K. To identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employee, the methodology and the material assumptions, adjustments, and estimates that we used were as follows:

We determined that, as of December 31, 2025, our employee population consisted of 4,124 individuals (including full-time and part-time employees, other than our Chief Executive Officer, who were employed on December 31, 2025) working at the Company together with our consolidated subsidiaries. Of these individuals, 3,853 were located in the U.S. and U.S. territories, and 271 were from our subsidiaries in Canada and Brazil. We chose to exclude all 193 of our employees from our Brazil subsidiary, which consists of 4.7% of our workforce, from the identification of “median employee,” as permitted by SEC rules.

Our employee population, after taking into consideration the permitted adjustments described above, consisted of 3,931 members. Our adjusted employee population consisted of 3,853 employees in the U.S. and 78 employees located in Canada.

We identified our median employee based on the total cash and stock-based compensation earned during the twelve-month period ended December 31, 2025. In making this determination, we annualized the compensation of all full- and part-time permanent employees included in the sample who were hired in calendar year 2025, but did not work for us or our included subsidiaries for the entire twelve-month period described below. For purposes of determining the total cash and stock-based compensation earned, we included: the amount of base salary (or, in the case of hourly workers, base wages including overtime pay) the employee received during the twelve months ended December 31, 2025, the amount of any cash incentives paid or deferred in such period (which include sales commissions as well as cash incentives that are generally paid for performance during the prior quarter or year), and the amount of any income from stock-based compensation, as reflected in our payroll records. For purposes of identifying the median employee, we applied the average exchange rate for calendar year 2025, which was U.S. dollars to Canadian dollars – 1.3973 CAD.

Once we identified our median employee, we then determined that employee’s annual total compensation, including any perquisites and other benefits, in the same manner that we determine the annual total compensation of our Named Executive Officers for purposes of the "Summary Compensation Table" beginning on page 53 disclosed above. The annual total compensation for our median employee for fiscal 2026 was determined to be $67,025. This amount was then compared to the annualized total compensation of our Chief Executive Officer disclosed above in the "Summary Compensation Table" beginning on page 53, of $6,509,647. The elements included in the Chief Executive Officer’s total compensation are discussed above in the footnotes to the "Summary Compensation Table" beginning on page 53.

Pay Versus Performance

Pay Versus Performance Table

As required by the Dodd-Frank Act and SEC regulation, the following table presents, for each of the five most recent fiscal years:

•total compensation, as calculated in the "Summary Compensation Table" beginning on page 53, for our current and former President and CEO (the “PEOs”) and an average for our Other Named Executive Officers (“Non-PEO NEOs”);

•compensation actually paid (“CAP”) to our current and former PEOs and an average for our Non-PEO NEOs, an SEC prescribed calculation which adjusts total compensation for the items described below and which does not equate to realized compensation;

•our cumulative total shareholder return (“TSR”) since the last trading day before the earliest year presented;

•our net income; and

•our adjusted earnings before interest, taxes, depreciation and amortization (“Adjusted EBITDA”).

For a description of our executive compensation program and the factors used by the Compensation Committee to determine pay for our NEOs, see the “Compensation Discussion and Analysis” section of this Proxy Statement.

(6)The peer group used in this Pay Versus Performance table is the S&P 600 Industrials Index, which is the same industry index the Company uses for purposes of the stock performance graph in our 2026 Annual Report on Form 10-K. We believe that the S&P 600 Industrials Index is the best available published industry index, composed of companies with similar market capitalization and a mix of GICS classifications that reasonably reflect our diverse business activities, although most of the direct competitors in our various business units are either privately owned or are divisions of larger, publicly owned companies.

(7)Fiscal 2023 Net Income was incorrectly reported as $87,900,000 in the Pay Versus Performance table of our 2023 Proxy Statement. In this Proxy Statement, Fiscal 2023 Net Income has been updated to match the Company's 2023 Annual Report on Form 10-K.

(8)Our company-selected measure, which is the measure we believe represents the most important financial performance not otherwise presented in the table above that we use to link compensation actually paid to our PEO and Non-PEO NEOs for fiscal 2026 to our performance is Adjusted EBITDA, a non-GAAP financial measure which is further defined on page 36, and in Appendix A to this Proxy Statement.

Most Important Financial Measures

The table below lists the most important financial measures used by the Company to link compensation actually paid to the Company’s PEO and non-PEO NEOs to the Company's performance during fiscal 2026.

Most Important Measures for Determining NEO Pay

Adjusted Earnings before Interest, Taxes, Depreciation and Amortization (either Consolidated or Operating Segment) (“Adjusted EBITDA”)

Adjusted Diluted EPS

Adjusted Return on Invested Capital (“Adjusted ROIC")

Net Sales

Proposal 2: Advisory Approval of Apogee’s Executive Compensation

Pursuant to Section 14A of the Exchange Act, we are providing shareholders with an advisory (non-binding) vote on the compensation of our Named Executive Officers as disclosed in this Proxy Statement in accordance with the rules of the SEC.

We are asking our shareholders to indicate their support for the compensation of our Named Executive Officers. We believe that our executive compensation program is structured in the best manner possible to support our Company and its business objectives. It has been designed to implement certain core compensation principles, which include:

•Alignment of management’s interests with our shareholders’ interests to support long-term value creation through our equity compensation programs and share ownership guidelines;

•Pay-for-performance, which is demonstrated by linking short-term cash incentives and long-term incentives to key financial measures;

•Providing a flexible compensation package that reflects the cyclical nature of our business and fairly compensates our executives over our business cycle; and

•Linking compensation to market levels of compensation paid to executive officers in the competitive market so that we can attract, motivate and retain executives who are able to drive the long-term success of Apogee.

We believe our executive compensation program reflects a strong pay-for-performance philosophy and is well-aligned with our shareholders’ long-term interests. Our executive compensation program is designed to motivate our executives, drive desirable behaviors, be competitive, promote retention and reward successful performance. We ask for your support for the reasons listed below.

•Our compensation programs are substantially tied to achievement of our key financial and business objectives. A significant portion of each Named Executive Officer’s potential total short-term cash compensation and long-term compensation is at-risk and linked to our operating performance.

•Our compensation programs are designed to take into account the cyclical nature of our business and to fairly compensate our executives over the non-residential construction cycle.

•Our compensation programs for executive officers deliver a significant portion of potential total compensation in the form of equity. If the value we deliver to our shareholders declines, so does the compensation we deliver to our executive officers.

•We have stock ownership guidelines for our executive officers.

•We offer very limited perquisites to our executive officers and do not provide tax reimbursement or “gross-ups” on perquisites.

•Each of our Named Executive Officers is expected to demonstrate exceptional individual performance in order to continue serving as a member of the executive team.

•We continue to refine our executive compensation program to reflect evolving executive compensation practices.

We believe that the information provided above and within the “Executive Compensation” section of this Proxy Statement demonstrates that our executive compensation program was designed appropriately and is working to ensure management’s interests are aligned with our shareholders’ interests to support long-term value creation. Accordingly, we are asking our shareholders to vote “FOR” the following resolution at the Annual Meeting:

“RESOLVED, that the shareholders approve, on an advisory basis, the compensation of Apogee’s Named Executive Officers, as disclosed in Apogee’s Proxy Statement for the 2026 Annual Meeting of Shareholders pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and other related narrative disclosures.”

73

This advisory vote on executive compensation is not binding on Apogee, our Compensation Committee or our Board of Directors. However, our Compensation Committee and Board of Directors will take into account the result of the vote when determining future executive compensation arrangements. We currently conduct annual advisory votes on executive compensation, and we expect to conduct our next advisory vote at our 2027 Annual Meeting of Shareholders.

Board Recommendation

Our Board of Directors recommends that you vote FOR the Say on Pay Proposal. Proxies will be voted FOR the proposal unless otherwise specified.

74

Proposal 3: Approval of The Apogee Enterprises, Inc. 2019 Stock Incentive Plan, as Amended and Restated (2026)

Background and Purpose

Our Board, on the recommendation of our Compensation Committee, approved on April 23, 2026 an amendment and restatement to the Apogee Enterprises, Inc. 2019 Stock Incentive Plan, as Amended and Restated (2026) (the “2019 Stock Plan”), subject to shareholder approval at the Annual Meeting. The proposed amendment and restatement would add an additional 800,000 shares to the 2019 Stock Plan share reserve. As of February 28, 2026, the last day of fiscal 2026, there were approximately 390,862 shares of our common stock remaining available for future awards under the current 2019 Stock Plan, which is the Company’s only equity-based compensation plan under which awards may be made to executive officers and other employees, other than the Legacy Partnership Plan, which has been frozen since 2008, pursuant to which 3,822 shares are available for issuance. The 2019 Stock Plan was originally approved by our shareholders on June 23, 2021. The purpose of the 2019 Stock Plan is to promote the interests of the Company and its shareholders by aiding the Company in attracting and retaining employees, officers, consultants and independent contractors capable of assuring the future success of the Company, by providing such persons with opportunities for stock ownership in the Company and to align the interests of such persons with those of our shareholders. The Board believes that it is in the best interest of the Company and our shareholders to further increase the maximum number of shares issuable under the 2019 Stock Plan to enable the Company to continue offering meaningful equity incentives to eligible participants. The Compensation Committee (for purposes of this summary, the “Committee”) administers the 2019 Stock Plan. The following discussion and summary of the material terms of the 2019 Stock Plan is qualified in its entirety by reference to the full text of the 2019 Stock Plan which is set forth in Appendix B to this proxy statement.

Proposed Amendment to the 2019 Stock Plan

The only change to the 2019 Stock Plan is to increase the aggregate number of shares that may be issued under the 2019 Stock Plan by 800,000 shares, from a total of 2,150,000 shares to 2,950,000 shares.

Key Features of the 2019 Stock Plan

The following features of the 2019 Stock Plan reflect equity incentive plan “best practices” intended to protect the interests of our shareholders:

•Limit on Shares Available for Awards. Under the 2019 Stock Plan, the aggregate number of shares of the Company’s common stock that may be issued is 2,950,000 shares, assuming approval of this Proposal at the Annual Meeting. All shares awarded, regardless of the type of award, will count against the 2019 Stock Plan’s reserve on a 1:1 basis for each share subject to the award. On the record date, the closing price of our common stock on the Nasdaq Global Select Market was $37.44 per share.

•Individual Limits on Shares Issued. The aggregate number of shares of the Company’s common stock that may be issued in a calendar year under the 2019 Stock Plan to an individual employee or officer is 200,000 shares and, in the case of a consultant, independent contractor or advisor is 30,000 shares.

•No Evergreen Provision. The 2019 Stock Plan does not contain an “evergreen” provision.

•No Liberal Share “Recycling.” The 2019 Stock Plan provides that any shares (i) surrendered to pay the exercise price of an option, (ii) withheld by the Company or tendered to satisfy tax withholding obligations with respect to any award, (iii) covered by a stock settled stock appreciation right not issued in connection with settlement upon exercise, or (iv) repurchased by the Company using option proceeds will not be added back (“recycled”) to the 2019 Stock Plan.

•No Granting of Discounted Stock Options or Stock Appreciation Rights. Stock options and stock appreciation rights (“SARs”) must have an exercise price equal to or greater than the fair market value of our common stock on the date of grant (unless such award is granted in substitution for a stock option or SAR previously granted by an entity that is acquired by or merged with the Company).

75

•No Repricing of Stock Options or SARs. The 2019 Stock Plan prohibits the repricing of stock options and SARs (including a prohibition on the repurchase of “underwater” stock options or stock appreciation rights for cash or other securities) without shareholder approval.

•No Liberal Change-in-Control. The 2019 Stock Plan prohibits any award agreement from having a change-in-control provision that has the effect of accelerating the exercisability of any award or the lapse of restrictions relating to any award upon only the announcement or shareholder approval (rather than the consummation of) a change-in-control transaction.

•No Dividends or Dividend Equivalents Paid on Unvested Awards. The 2019 Stock Plan prohibits the payment of dividends or dividend equivalents on awards until those awards are earned and vested. In addition, the 2019 Stock Plan prohibits the granting of dividend equivalents with respect to stock options, SARs or an award the value of which is based solely on an increase in the value of the Company’s shares after the grant of the award.

•Awards Subject to Forfeiture or Clawback. Awards under the 2019 Stock Plan will be subject to any Company recovery or clawback policy, as well as any other forfeiture and penalty conditions determined by the Committee.

•Minimum Vesting Period. A maximum of 5% of the aggregate number of shares available for issuance under the 2019 Stock Plan may be issued without a vesting period of at least one year following the date of grant. All other awards will have a minimum vesting period of at least one year.

•Independent Committee Administration. The 2019 Stock Plan will be administered by a committee of the Board of Directors comprised entirely of independent directors.

The Committee expects that the number of shares available, if approved by our shareholders, will satisfy equity compensation needs for approximately three years based on historical grant practices.

Determination of Number of Shares for the 2019 Stock Plan

In setting the number of shares authorized under the 2019 Stock Plan for which shareholder approval is being sought, the Committee and the Board of Directors considered, among other factors, the historical amounts of equity awards granted by the Company and the potential future grants over the next three years. Below is information regarding the Company’s burn rates for all grants of equity under all shareholder-approved equity plans for the past three fiscal years and the Company’s total potential dilution.

Burn Rate. Burn rate is a measure of the level at which a company uses shares available for grant under its equity compensation plans, and is an important factor for investors concerned about shareholder dilution. Burn rate is defined as, in a given fiscal year, the number of shares subject to equity awards granted divided by the weighted average number of shares outstanding. In setting and recommending to our shareholders the number of shares to be authorized under the 2019 Stock Plan, the Board considered the Company’s burn rate for each of the past three fiscal years. The calculation of our burn rate for each year is shown in the table below:

						Fiscal Year Ended February 28, 2026						Fiscal Year Ended March 1, 2025						Fiscal Year Ended March 2, 2024
Full Value Awards Granted						440,956						214,141						247,621
Stock Options Awards Granted						—						—						—
Total Awards Granted						440,956						214,141						247,621
Weighted Average Shares of Common Stock Outstanding (Basic)						21,295,000						21,726,000						21,871,000
Burn Rate						2.07%						0.99%						1.13%

Based on the burn rates in fiscal years 2026, 2025 and 2024, our three-year average burn rate was 1.40%.

Overhang. The potential dilution, or overhang, is a common measure to assess the dilutive impact of equity plans. Total potential dilution is equal to (i) the number of shares available to be granted as future equity awards plus the number of shares subject to outstanding equity awards, divided by (ii) such total number of shares plus the total number of shares outstanding. Total potential dilution, prior to and after shareholder approval of the proposed amendment and restatement of the 2019 Stock Plan, is shown in the table below:

						Total Potential Dilution
Remaining Reserve under 2019 Stock Incentive Plan ("2019 Stock Incentive Plan")(1)						390,862
Remaining Reserve under 2019 Non-Employee Director Stock Plan, Legacy Partnership Plan and Deferred Compensation Plan for Non-Employee Directors ("Other Stock Plans")(1)						143,704
Shares Subject to Outstanding Awards under 2019 Stock Incentive Plan, Other Stock Plans and New Hire Awards ("Outstanding Awards")(1)						230,273
Weighted Average Shares of Common Stock Outstanding (Basic) ("CSO")(1)						21,295,000
Total Current Dilution(2)						3.47%
Additional Shares Reserved under 2019 Stock Incentive Plan						800,000
Total Potential Dilution(3)						6.85%

___________________________

(1)As of February 28, 2026.

(2)Calculated as (2019 Stock Incentive Plan + Other Stock Plans + Outstanding Awards), divided by (2019 Stock Incentive Plan + Other Stock Plans + Outstanding Awards + CSO).

(3)Calculated as (2019 Stock Incentive Plan + Other Stock Plans + Outstanding Awards + Additional Shares Reserved under 2019 Stock Incentive Plan), divided by (2019 Stock Incentive Plan + Other Stock Plans + Outstanding Awards + Additional Shares Reserved under 2019 Stock Incentive Plan + CSO).

The 2019 Stock Plan does not set the number of shares subject to equity awards that will be granted in future years. In setting each year’s award amounts for plan participants, the Committee considers a variety of factors such as: the relative market position of the awards, the proportion of each executive’s total compensation to be delivered as a long-term incentive award, internal pay equity, executive performance, retention concerns, and the Company’s performance. The closing price of a share of the Company's common stock on the Nasdaq Global Select Market on April 27, 2026 was $37.44 per share.

New Plan Benefits

The number and types of awards that will be granted under the 2019 Stock Plan in the future are not determinable at this time, as the Committee will make these determinations in its discretion, subject to the terms of the 2019 Stock Plan.

The following table sets forth summary information concerning the number of shares of our common stock subject to restricted stock grants, restricted stock unit and deferred restricted stock units grants and performance share unit grants (at target) made under the 2019 Stock Incentive Plan to our Named Executive Officers, non-employee directors, and employees in fiscal 2026.

Description of 2019 Stock Plan

Administration. The Committee administers the 2019 Stock Plan and has full power and authority to determine when and to whom awards will be granted, and the type, amount and other terms and conditions of each award, consistent with the provisions of the 2019 Stock Plan. Subject to the provisions of the 2019 Stock Plan, the Committee may amend the terms of, or accelerate the exercisability of, an outstanding award. The Committee will have authority to interpret the 2019 Stock Plan and establish rules and regulations for the administration of the 2019 Stock Plan.

The Committee may delegate its powers under the 2019 Stock Plan to the Chief Executive Officer and/or one or more executive officers, subject to the requirements of applicable law and exchange requirements. However, such delegated officers will not be permitted to grant awards to any members of the Board or executive officers who are subject to Section 16 of the Exchange Act.

Eligibility. Any employee, officer, consultant or independent contractor providing services to Apogee Enterprises, Inc. or an affiliate, or any person to whom an offer of employment or engagement has been made, and who is selected by the Committee to participate, is eligible to receive an award under the 2019 Stock Plan. The number of persons eligible to participate as of April 27, 2026 (the record date for the meeting), had the 2019 Stock Plan been in effect, is estimated to be approximately 4,107 employees, eight officers and no consultants or independent contractors; however, historically the Committee has not granted awards to more than approximately 100 employees in any single fiscal year.

Shares Available for Awards. If this Proposal to increase the share reserve is approved, the aggregate number of shares that may be issued under all stock-based awards made under the 2019 Stock Plan will be 2,950,000 shares. All shares subject to awards, regardless of the type of award, will count against the 2019 Stock Plan’s reserve on a 1:1 basis for each share subject to the award. If awards issued under the 2019 Stock Plan expire or otherwise terminate without being exercised or settled, the shares of common stock not acquired pursuant to such awards again become available for issuance under the 2019 Stock Plan. However, under the share counting provisions of the 2019 Stock Plan, the following classifications of shares will not again be available for issuance: (i) shares unissued due to a “net exercise” of a stock option, (ii) any shares withheld or shares tendered to satisfy tax withholding obligations under any award, (iii) shares covered by a SAR that is not settled in shares upon exercise, and (iv) shares repurchased using stock option exercise proceeds.

Awards under the 2019 Stock Plan are also subject to annual limitations. No individual employee or officer may be granted awards under the 2019 Stock Plan for more than 200,000 shares of our common stock in any calendar year. No consultant or independent contractor may be granted awards under the 2019 Stock Plan for more than 30,000 shares of our common stock in any calendar year.

The Committee can adjust the number of shares and share limits described above in the case of a stock dividend, recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split-off, repurchase or exchange of shares, or other similar corporate transaction where such an adjustment is necessary to prevent dilution or enlargement of the benefits available under the 2019 Stock Plan. Any adjustment determination made by the Committee shall be final, binding and conclusive.

Type of Awards and Terms and Conditions. The 2019 Stock Plan provides that the Committee may grant awards to eligible participants in any of the following forms, subject to such terms, conditions and provisions as the Committee may determine to be necessary or desirable:

• stock options, including both incentive stock options (“ISOs”) and non-qualified stock options (together with ISOs, “options”);

• stock appreciation rights (“SARs”);

• restricted stock;

• restricted stock units;

• dividend equivalent rights; and

• other stock-based awards.

79

The Committee will have the right to make the timing of the grant and/or the issuance, ability to retain, vesting, exercise and/or settlement of awards subject to completion of a minimum period of service, achievement of one or more performance goals or both as deemed appropriate by the Committee; provided, that a maximum of five percent of the aggregate number of shares available for issuance under the 2019 Stock Plan may be issued with the terms providing for a right of exercise or a lapse on any vesting condition earlier than a date that is at least one year following the date of grant (or, in the case of vesting based upon performance-based objectives, exercise and vesting restrictions cannot lapse earlier than the one-year anniversary, measured from the commencement of the period over which performance is evaluated). The Committee will also have the right to determine whether awards are exercised or payable in shares, cash or a combination thereof.

1.Options and SARs. The holder of an option is entitled to purchase a number of shares of our common stock at a specified exercise price during a specified time period, all as determined by the Committee. The holder of a SAR is entitled to receive the excess of the fair market value (calculated as of the exercise date) of a specified number of shares of our common stock over the grant price of the SAR. We would receive no consideration for options or SARs granted under the 2019 Stock Plan, other than the services rendered by the holder in his or her capacity as an employee, officer, consultant or independent contractor of the Company.

Exercise Price. The exercise price per share of an option or SAR will in no event be less than 100% of the fair market value per share of our common stock underlying the award on the date of grant, unless such award is granted in substitution for an option or SAR previously granted by a merged or acquired entity. Without the approval of shareholders, we will not amend or replace previously granted options or SARs in a transaction that constitutes a “repricing” as defined in the 2019 Stock Plan.

Vesting. The Committee has the discretion to determine when and under what circumstances an option or SAR will vest, subject to minimum vesting provisions described above.

Exercise. The Committee has the discretion to determine the method or methods by which an option or SAR may be exercised, which methods may include a net exercise. The Committee is not authorized under the 2019 Stock Plan to accept a promissory note as consideration.

Expiration. Options and SARs will expire at such time as the Committee determines; provided, however, that no option or SAR may be exercised more than ten years from the date of grant. Furthermore, notwithstanding the foregoing, in the case of an ISO granted to a 10% shareholder, the option may not be exercised more than five years from the date of grant.

Special Limitations on ISOs. In the case of a grant of an option intended to qualify as an ISO, no such option may be granted to a participant who owns, at the time of the grant, stock representing more than 10% of the total combined voting power of all classes of our stock or our subsidiaries unless the exercise price per share of our common stock subject to such ISO is at least 110% of the fair market value per share of our common stock on the date of grant, and such ISO award is not exercisable more than five years after its date of grant. In addition, options designated as ISOs shall not be eligible for treatment under the Internal Revenue Code as ISOs to the extent that either: (i) the aggregate fair market value of shares of common stock (determined as of the time of grant) with respect to which such ISOs are exercisable for the first time by the participant during any calendar year exceeds $100,000 or (ii) such ISOs otherwise remain exercisable but are not exercised within three months after termination of employment (or such other period of time provided in Section 422 of the Internal Revenue Code).

2.Restricted Stock and Restricted Stock Units. The holder of restricted stock will own shares of our common stock subject to restrictions imposed by the Committee for a specified time period determined by the Committee. The holder of restricted stock units will have the right, subject to restrictions imposed by the Committee, to receive shares of our common stock at some future date determined by the Committee. The grant, issuance, retention, vesting and/or settlement of restricted stock and restricted stock units will occur at such times and in such installments as are determined by the Committee, subject to the minimum vesting provisions described above.

80

3.Dividend Equivalents. The holder of a dividend equivalent will be entitled to receive payments (in cash or shares of our common stock) equivalent to the amount of cash dividends paid by the Company to shareholders with respect to the number of shares determined by the Committee. Dividend equivalents will be subject to other terms and conditions determined by the Committee, but the Committee may not (i) grant dividend equivalents in connection with options or SARs, or (ii) pay a dividend equivalent with respect to a share underlying an award prior to the date on which all conditions or restrictions on such share have been satisfied or lapsed.

4.Other Stock-Based Awards. The Committee is also authorized to grant other types of awards that are denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to shares of our common stock, subject to terms and conditions determined by the Committee and the limitations in the 2019 Stock Plan. No such stock-based awards will contain a purchase right or an option-like exercise feature.

Termination and Amendment. The 2019 Stock Plan has a term of ten years expiring on June 25, 2029, unless terminated earlier by the Board. The Board may from time to time amend, suspend or terminate the 2019 Stock Plan. No amendment or modification of the 2019 Stock Plan may be made that would adversely affect any outstanding award without the consent of the participant or the current holder of the award (except in the case of a corporate transaction as described below). Amendments to the 2019 Stock Plan must be approved by the shareholders, if required under the listing requirements of the Nasdaq Global Select Market or any other securities exchange applicable to the Company, or if the amendment would (i) increase the number of shares authorized under the 2019 Stock Plan, (ii) permit a repricing of options or SARs, (iii) permit the award of options or SARs with an exercise price less than 100% of the fair market value of a share on the date of grant, (iv) increase the maximum term of options or SARs, or (v) increase the annual per-person share limits under the 2019 Stock Plan.

Effect of Corporate Transaction. Awards under the 2019 Stock Plan are generally subject to special provisions upon the occurrence of any reorganization, merger, consolidation, split-up, spin-off, combination, plan of arrangement, take-over bid or tender offer, repurchase or exchange of shares, or any other similar corporate transaction or event involving the Company. In the event of such a corporate transaction, the Committee or the Board may provide for any of the following to be effective upon the occurrence of the event (or effective immediately prior to the consummation of such event, provided the event is consummated):

•termination of any award, whether vested or not, in exchange for an amount of cash and/or other property equal to the amount that would have been attained upon exercise of the award or the realization of the participant’s rights under the award. Awards may be terminated without payment if the Committee or Board determines that no amount is realizable under the award as of the time of the transaction;

•replacement of any award with other rights or property selected by the Committee or the Board of Directors, in its sole discretion;

•the assumption of any award by the successor or survivor entity (or its parent or subsidiary) or the arrangement for the substitution for similar awards covering the stock of such successor entity with appropriate adjustments as to the number and kind of shares and prices;

•require that any award shall become exercisable or payable or fully vested, notwithstanding anything to the contrary in the applicable award agreement; or

•require that the award cannot vest, be exercised or become payable until after a future date, which may be the effective date of the corporate transaction.

Limited Transferability of Awards. Generally, no award or other right or interest of a participant under the 2019 Stock Plan (other than fully vested and unrestricted shares issued pursuant to an award) shall be transferable by a participant other than by will or by the laws of descent and distribution, and no right or award may be pledged, alienated, attached or otherwise encumbered, and any purported pledge, alienation, attachment or encumbrance shall be void and unenforceable against the Company or any affiliates. However, the Committee may allow transfer of an award to family members for no value, and such transfer shall comply with the General Instructions to Form S-8 under the Securities Act of 1933, as amended. The Committee may establish procedures to allow a named beneficiary to exercise the rights of the participant and receive any property distributable with respect to any award upon the participant’s death.

81

Federal Income Tax Consequences

Grant of Options and SARs. The grant of a stock option or SAR is not expected to result in any taxable income to the recipient.

Exercise of Options and SARs. Upon exercising a non-qualified stock option, the optionee must recognize ordinary income equal to the excess of the fair market value of the shares of the Company’s common stock acquired on the date of exercise over the exercise price, and we generally will be entitled at that time to an income tax deduction for the same amount. The holder of an ISO generally will have no taxable income upon exercising the option (except that an alternative minimum tax liability may arise), and we will not be entitled to an income tax deduction. Upon exercising a SAR, the amount of any cash received and the fair market value on the exercise date of any shares of our common stock received are taxable to the recipient as ordinary income and generally are deductible by us.

Disposition of Shares Acquired Upon Exercise of Options and SARs. The tax consequence upon a disposition of shares acquired through the exercise of an option or SAR will depend on how long the shares have been held and whether the shares were acquired by exercising an ISO or by exercising a non-qualified stock option or SAR. Generally, there will be no tax consequence to the Company in connection with the disposition of shares acquired under an option or SAR, except that the Company may be entitled to an income tax deduction in the case of the disposition of shares acquired under an ISO, if the disposition occurs before the applicable ISO holding periods set forth in the Internal Revenue Code have been satisfied.

Awards Other than Options and SARs. If an award is payable in shares of our common stock that are subject to substantial risk of forfeiture, unless a special election is made by the holder of the award under the Internal Revenue Code, the holder must recognize ordinary income equal to the excess of: (i) the fair market value of the shares received (determined as of the first time the shares become transferable or not subject to substantial risk of forfeiture, whichever occurs earlier) over (ii) the amount (if any) paid for the shares by the holder of the award. We will generally be entitled at that time to an income tax deduction for the same amount. As to other awards granted under the 2019 Stock Plan that are payable either in cash or shares of our common stock not subject to substantial risk of forfeiture, the holder of the award must recognize ordinary income equal to: (a) the amount of cash received or, as applicable, (b) the excess of (i) the fair market value of the shares received (determined as of the date such shares are received) over (ii) the amount (if any) paid for the shares by the holder of the award.

Income Tax Deduction. Subject to the usual rules concerning reasonable compensation, including our obligation to withhold or otherwise collect certain income and payroll taxes, we generally will be entitled to a corresponding income tax deduction at the time a participant recognizes ordinary income from awards made under the 2019 Stock Plan. However, Section 162(m) of the Code prohibits publicly held corporations from deducting more than $1 million per year in compensation paid to certain named executive officers. The Tax Cuts and Jobs Act (the “Act”), which was signed into law at the end of 2017, made significant changes to the deduction limit under Section 162(m), which are effective for taxable years beginning on and after January 1, 2018. The Act eliminated the exception to the deduction limit for qualified performance-based compensation and broadens the application of the deduction limit to certain current and former executive officers who previously were exempt from such limit. Therefore, compensation paid to a covered executive under the 2019 Stock Plan in excess of $1 million generally will not be deductible.

Special Rules for Executive Officers Subject to Section 16 of the Exchange Act. Special rules may apply to individuals subject to Section 16 of the Exchange Act. In particular, unless a special election is made pursuant to the Internal Revenue Code, shares received through the exercise or settlement of an award may be treated as restricted as to transferability and subject to a substantial risk of forfeiture for a period of up to six months after the date of exercise. Accordingly, the amount of any ordinary income recognized and the amount of our income tax deduction will be determined as of the end of that period.

Section 409A of the Internal Revenue Code. The Committee intends to administer and interpret the 2019 Stock Plan and all award agreements in a manner consistent to satisfy the requirements of Section 409A of the Internal Revenue Code to avoid any adverse tax results thereunder to a holder of an award.

82

Equity Compensation Plan Information

The following table summarizes, with respect to our equity compensation plans, the number of shares of our common stock to be issued upon exercise of outstanding options, warrants and other rights to acquire shares, the weighted-average exercise price of these outstanding options, warrants and rights, and the number of shares remaining available for future issuance under our equity compensation plans as of February 28, 2026, the last day of fiscal 2026.

Dividends accrue on the outstanding performance share units during the three-year performance periods but will be paid only on shares earned at the end of each performance cycle. Certain outstanding restricted stock units have dividend rights attached, but none of the restricted stock units are transferable.

(2)At the beginning of fiscal years 2024, 2025 and 2026, performance share units were awarded to plan participants which will vest based on our Company’s performance over each three-year performance period. The performance share units represent the right to receive shares of our common stock at the end of each three-year performance period. Pursuant to SEC rules and the reporting requirements for this table, we have included in this column 75,783 shares underlying the outstanding performance share units at maximum performance, assuming our Company performed at the maximum level during the applicable performance periods. Only 38,544 shares underly the performance awards at target level performance.

(3)In calculating the Weighted-Average Exercise Price of Outstanding Options, Warrants and Rights, restricted stock, restricted stock units and phantom shares do not have an exercise price.

(4)Pursuant to SEC Rules and the reporting requirements for this table, of these shares, 3,822 are available for issuance under our Legacy Partnership Plan; 390,862 are available for grant under our 2019 Stock Incentive Plan; 125,142 are available for grant under our 2019 Non-Employee Director Stock Plan; and 14,740 are available for grant under our prior Deferred Compensation Plan for Non-Employee Directors.

Proposal 4: Ratification of Appointment of Independent

Registered Public Accounting Firm

Our Audit Committee has appointed Deloitte & Touche LLP (“Deloitte”) as our independent registered public accounting firm for the fiscal year ending February 27, 2027, subject to a satisfactory evaluation of the firm’s performance in conducting our fiscal 2026 audit. Deloitte has served as our independent registered public accounting firm since fiscal 2003. The Audit Committee is responsible for the appointment, compensation and oversight of Deloitte and believes that the retention of Deloitte is in the best interests of the Company and its shareholders.

While it is not required to do so, our Board of Directors is submitting the appointment of Deloitte to serve as our independent registered public accounting firm for the fiscal year ending February 27, 2027, to our shareholders for ratification as a matter of good corporate governance.

If shareholders do not ratify the selection of Deloitte, the Audit Committee will consider whether it is appropriate to select another Independent Accounting Firm. Even if the selection of Deloitte is ratified by shareholders, the Audit Committee may, in its discretion, appoint a different firm of Independent Auditors at any time during the year if it determines that such a change would be in the best interests of the Company and our shareholders.

We have been advised that a representative from Deloitte will be present at the Annual Meeting. The representative will be available to respond to appropriate questions and will be given the opportunity to make a statement if the firm so desires.

Board Recommendation

Our Board of Directors recommends that you vote FOR the proposal to ratify the appointment of Deloitte & Touche LLP as our independent registered public accounting firm for the fiscal year ending February 27, 2027. Proxies will be voted FOR the proposal unless otherwise specified.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services

Consistent with policies of the SEC regarding auditor independence, our Audit Committee has responsibility for appointing, setting compensation and overseeing the work of our independent registered public accounting firm. In recognition of this responsibility, our Audit Committee established a policy to require pre-approval of all audit and permissible non-audit services provided by our independent registered public accounting firm. As permitted by regulations of the SEC, our Audit Committee delegated the authority to pre-approve services provided by our independent registered public accounting firm to the Chair of our Audit Committee, who reports any pre-approval decisions to our Audit Committee at its next regularly scheduled meeting.

All of the services provided by our independent registered public accounting firm in fiscal 2026 and 2025, including services related to the audit-related fees, tax fees and all other fees described above, were approved by our Audit Committee under its pre-approval policy.

Frequently Asked Questions

Who is entitled to vote at the meeting?

Our Board of Directors has set April 27, 2026, as the record date for the Annual Meeting. If you were a shareholder at the close of business on the record date, you are entitled to notice of and to vote at the Annual Meeting.

As of the record date, 21,351,005 shares of common stock, par value $0.33-1/3, were issued and outstanding and, therefore, eligible to vote at the Annual Meeting.

What are my voting rights?

Holders of our common stock are entitled to one vote per share. Therefore, 21,351,005 votes are entitled to be cast at the Annual Meeting. There is no cumulative voting for the election of directors.

How many shares must be present to hold the meeting?

In accordance with our Amended and Restated By-laws, shares equal to at least a majority of the voting power of the outstanding shares of our common stock as of the record date must be present at the Annual Meeting in order to hold the Annual Meeting and conduct business. This is called a quorum. Your shares are counted as present at the Annual Meeting if:

•you are present and vote in person at the Annual Meeting, with virtual participation constituting in person presence at the meeting;

•you have properly submitted a proxy via the Internet, by telephone, or by mail, even if you abstain from voting on one or more matters; or

•you hold your shares in street name (as discussed under “What is the difference between a shareholder of record and a “street name” holder?” beginning on page 91) and you did not provide voting instructions to your broker and your broker uses its discretionary authority to vote your shares on the ratification of the appointment of our independent registered public accounting firm.

How can I attend the meeting?

In order to expand access to the Annual Meeting, we are holding the Annual Meeting in a virtual-only meeting format. You will not be able to attend the Annual Meeting at a physical location.

___________________________

(1)A “broker non-vote” occurs when a nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that proposal and has not received voting instructions from the beneficial owner. If a broker returns a “non-vote” proxy indicating a lack of authority to vote on a proposal, then the shares covered by such a “non-vote” proxy will be deemed present at the meeting for purposes of determining a quorum, but generally are not counted or deemed to be present in person or by proxy for the purpose of voting on Proposals 1 through 3.

(2)Section 5.02 of the Company’s Articles of Incorporation requires that a director nominee will be elected only if they receive a majority of the votes cast with respect to their election in an uncontested election, that is, the number of shares “for” that nominee exceeds the number of votes cast “against” that nominee. A vote to “abstain” will not have any effect on determining the election results. If a director nominee is not elected and the nominee is an incumbent director, that director shall promptly tender their resignation to the Board of Directors, subject to acceptance by the Board of Directors. In that event, the Nominating and Corporate Governance Committee must make a recommendation to the Board on whether to accept or reject the tender of resignation. The Board, after taking into account the recommendation, must publicly disclose its decision and rationale within 90 days after the election. The director who failed to receive a majority vote will not participate in the decision.

(3)The voting standard assumes that the number of shares voted in favor of such proposal constitute more than 25% of the outstanding shares of our common stock.

89

How can I ask questions during the Annual Meeting?

You may submit questions in real time during the Annual Meeting following the formal business portion of the meeting, by entering them into the field provided on the meeting website. The directors and executive management will answer appropriate questions from shareholders. To allow us to answer questions from as many shareholders as possible, we will limit each shareholder to two questions. It will help us if questions are succinct and cover only one topic.

How do I cast my vote?

Your vote is important. If you are a shareholder of record, you can give a proxy to be voted at the Annual Meeting in any of the following ways:

•electronically via the Internet by following the “Vote by Internet” instructions on the Notice or, if you received paper copies of our proxy materials, on the enclosed proxy card;

•by telephone by following the “Vote by Telephone” instructions on the Notice or, if you received paper copies of our proxy materials, on the proxy card;

•by completing, signing and mailing the proxy card (if you received paper copies of our proxy materials); or

•by attending the virtual Annual Meeting and voting online on the meeting website.

If you are an employee and received our 2026 proxy materials electronically via the Internet at your company email address, you will only be able to give a proxy to be voted at the Annual Meeting electronically via the Internet as described under “How do I vote if my shares are held in the Employee Stock Purchase Plan or other plans of Apogee?” below.

If you hold your shares in street name, you must vote your shares in the manner prescribed by your broker or other nominee. Your broker or other nominee has enclosed or otherwise provided a voting instruction card for you to use in directing the broker or other nominee how to vote your shares.

If you properly submit your proxy via the Internet, by telephone or return your executed proxy by mail and do not revoke your proxy, it will be voted in the manner you specify. If you submit a proxy without giving specific voting instructions, the proxies will vote those shares as recommended by the Board.

How do I vote if my shares are held in the Employee Stock Purchase Plan or other plans of Apogee?

If you hold any shares in our Employee Stock Purchase Plan or other plans of Apogee, your Internet proxy vote or completed proxy card will serve as voting instructions to the plan trustee or plan custodian, as applicable. However, your voting instructions for these plans must be received by 12:00 p.m. (noon) Eastern Time on Monday, June 22, 2026 in order to count. If you are a participant in our Employee Stock Purchase Plan, the plan custodian cannot vote your shares unless it receives timely instructions from you.

If you hold shares in our Employee Stock Purchase Plan or other plans of Apogee and have a company email address, you will receive our 2026 Proxy Statement and 2026 Annual Report to Shareholders electronically at your company email address instead of receiving paper copies of these documents in the mail. The email will provide instructions and a control number to use to provide voting instructions to the plan trustee via the Internet. If you receive our 2026 Proxy Statement and 2026 Annual Report to Shareholders electronically, you may only provide voting instructions to the plan trustee or plan custodian, as applicable, via the Internet and you will not receive a proxy card that can be returned by mail.

What does it mean if I receive more than one proxy card?

If you receive more than one proxy card, it means that you hold shares registered in more than one account in different names or variations of your name. To ensure that all of your shares are voted, if you submit your proxy vote via the Internet or by telephone vote once for each proxy card you received or sign and return each proxy card.

You may prefer to hold your shares in more than one account, and you are welcome to do so. However, please contact our Investor Relations Department at IR@apog.com or (877) 752-3432 (telephone) for information on how to merge your accounts.

Who will count the vote?

Representatives of Broadridge Financial Solutions, Inc., our tabulating agent, will tabulate the votes and act as independent inspector of election.

What if I do not specify how I want my shares voted?

If you submit your proxy via the Internet or telephone or a signed proxy card and do not specify how you want to vote your shares, we will vote your shares FOR all nominees and proposals. As of the date of this Proxy Statement, we know of no other matters that will be presented for a shareholder vote at the Annual Meeting. If any other matters properly come before the Annual Meeting for a shareholder vote, they will be voted in the discretion of the persons named in the proxy.

Can I change my vote after submitting my proxy or voting instructions?

Yes. If you are a shareholder of record, you may revoke your proxy and change your vote at any time before your proxy is voted at the Annual Meeting, in any of the following ways:

•by sending a written notice of revocation to our Corporate Secretary;

•by submitting a later-dated proxy to our Corporate Secretary;

•by submitting a later-dated proxy via the Internet;

•by submitting a later-dated proxy by telephone; or

•by voting in person at the meeting.

If you hold your shares in street name, you should contact your broker, bank, trust or other nominee for information on how to revoke your voting instructions and provide new voting instructions.

If you hold shares in our Employee Stock Purchase Plan or other plans of Apogee, you may revoke your proxy and change your voting instructions at any time, but no later than 12:00 p.m. (noon) Eastern Time on Monday, June 22, 2026, in any of the following ways:

•by sending a written notice of revocation to the plan trustee or plan custodian;

Shareholders who wish to obtain additional copies of our 2026 Annual Report to Shareholders on Form 10-K may do so without charge by contacting us through one of the following methods:

Internet:			www.apog.com
Email:			IR@apog.com
Telephone:			(877) 752-3432
Mail:			Investor Relations Apogee Enterprises, Inc. 4400 West 78th Street, Suite 520 Minneapolis, Minnesota 55435

How do I get electronic access to the proxy materials?

The Notice provides you with instructions regarding how to view the proxy materials for the Annual Meeting on the Internet.

Our 2026 Proxy Statement and 2026 Annual Report to Shareholders, including our Annual Report on Form 10-K, are available at www.proxyvote.com.

What is a proxy?

A proxy is your designation of another person to vote stock you own. That other person is called a proxy. If you designate someone as your proxy in a written document, that document also is called a proxy or a proxy card. When you designate someone a proxy, you may also direct the proxy how to vote your shares. We refer to this as your “proxy vote.” Three of our executive officers, Donald A. Nolan, Mark R. Augdahl and Bryan A. Welp, have been designated as the proxies for shareholders voting on the enclosed proxy card at the Annual Meeting.

What is the difference between a shareholder of record and a “street name” holder?

If your shares are registered directly in your name, you are considered the shareholder of record with respect to those shares.

If your shares are held in a stock brokerage account or by a bank, trust or other nominee, then the broker, bank, trust or other nominee is considered to be the shareholder of record with respect to those shares. However, you still are considered the beneficial owner of those shares, and your shares are said to be held in “street name.” Street name holders generally cannot vote their shares directly and must instead instruct the broker, bank, trust or other nominee how to vote their shares using the voting instruction form provided by the broker, bank, trust or other nominee.

Who pays for the cost of proxy preparation and solicitation?

We pay for the cost of proxy preparation and solicitation, including the reasonable charges and expenses of brokers and other nominees for forwarding proxy materials to the beneficial owners of our shares.

We are soliciting proxies primarily by mail and email. In addition, some of our officers and regular employees may solicit the return of proxies by telephone, facsimile, personal interview or email. These individuals will receive no additional compensation for these services.

How can I recommend or nominate a director candidate?

Our Nominating and Corporate Governance Committee considers recommendations of director candidates. A shareholder who wishes to recommend a director candidate to our Nominating and Corporate Governance

92

Committee for nomination by our Board of Directors at our next annual meeting, or for vacancies on our Board of Directors that arise between meetings, must provide our Nominating and Corporate Governance Committee with sufficient written documentation to permit a determination by our Nominating and Corporate Governance Committee and our Board of Directors as to whether such candidate meets the required and desired director selection criteria set forth in our Corporate Governance Guidelines and the factors discussed under the heading “Criteria for Membership on Our Board of Directors” above. Such documentation and the name of the director candidate must be sent by U.S. mail to our Corporate Secretary at Apogee Enterprises, Inc., 4400 West 78th Street, Suite 520, Minneapolis, MN 55435, no later than January 12, 2027. Our Corporate Secretary will send properly submitted shareholder recommendations to the Chair of our Nominating and Corporate Governance Committee for consideration at a future committee meeting.

Director candidates recommended by shareholders in compliance with these procedures and who meet the criteria outlined above will be evaluated by our Nominating and Corporate Governance Committee in the same manner as nominees proposed by other sources.

Alternatively, shareholders may directly nominate a person for election to our Board of Directors at a future annual meeting by complying with the procedures set forth in our Amended and Restated By-laws and the rules and regulations of the SEC. Our Amended and Restated By-laws are available on our website at www.apog.com by clicking on “Investors,” select “Governance,” then “By-laws.”

Shareholders who wish to nominate a director candidate for the 2027 Annual Meeting should submit the advance notice, along with other required information, to our Corporate Secretary at Apogee Enterprises, Inc., 4400 West 78th Street, Suite 520, Minneapolis, MN 55435, no later than February 24, 2027. To comply with universal proxy rules, the advance notice must comply with the additional requirements of Rule 14a-19(b) of the Exchange Act.

How can I present a proposal at the 2027 Annual Meeting of Shareholders?

Any shareholder wishing to have a proposal considered for inclusion in our Proxy Statement for our 2027 Annual Meeting of Shareholders must submit the proposal in writing to our Corporate Secretary at Apogee Enterprises, Inc., 4400 West 78th Street, Suite 520, Minneapolis, MN 55435 in accordance with all applicable rules and regulations of the SEC, including Rule 14a-8, no later than January 12, 2027.

Under our Amended and Restated By-laws, a shareholder proposal not included in our Proxy Statement for the 2027 Annual Meeting of Shareholders is untimely and may not be presented in any manner at the 2027 Annual Meeting of Shareholders unless the shareholder wishing to make the proposal follows the notice procedures set forth in our Amended and Restated By-laws. Any such shareholder proposals for the 2027 Annual Meeting of Shareholders must be in the form and substance required by the Amended and Restated By-laws and must be submitted to our Corporate Secretary at the address indicated on the Notice of Annual Meeting of Shareholders no later than February 24, 2027.

What is “householding” of proxy materials?

The SEC rules allow a single copy of the proxy statement and Annual Report to Shareholders to be delivered to multiple shareholders sharing the same address and last name, or who we reasonably believe are members of the same family, and who consent to receive a single copy of these materials in a manner provided by these rules. This practice is referred to as “householding” and can result in significant savings of paper and mailing costs. Although we do not household for our registered shareholders, some brokers household Apogee notices, proxy statements and annual reports, delivering single copies of such documents to multiple shareholders sharing an address unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be householding materials to your address, householding will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in householding and would prefer to receive a separate copy of our proxy statement and annual report, or if you are receiving multiple copies of documents and wish to receive only one, please notify your broker. We will promptly deliver upon written or oral request a separate copy of our proxy statement and/or Annual Report to Shareholders to a shareholder at a shared address to which a single copy of any such

93

document was delivered. For copies of these documents, shareholders should write to our Investor Relations Department at the address listed above, or call (877) 752-3432.

By Order of the Board of Directors,

Bryan A. Welp

Vice President, General Counsel and Secretary

Appendix B

Apogee Enterprises, Inc.

2019 Stock Incentive Plan, As Amended and Restated (2026)

Unless otherwise expressly provided in the Plan, all designations, determinations, interpretations and other decisions under or with respect to the Plan or any Award or Award Agreement shall be within the sole discretion of the Committee, may be made at any time and shall be final, conclusive and binding upon any Participant, any holder or beneficiary of any Award or Award Agreement, and any employee of the Company or any Affiliate.

(b)    Delegation. The Committee may delegate its powers and duties under the Plan to one or more Directors (including a Director who is also an officer of the Company) or a committee of Directors and may authorize one or more officers of the Company to grant Awards under the Plan, subject to such terms, conditions and limitations as the Committee may establish in its sole discretion; provided, however, that the Committee shall not delegate its powers and duties under the Plan with regard to officers of the Company or

Notwithstanding anything to the contrary contained herein, the Board may, at any time and from time to time, without any further action of the Committee, exercise the powers and duties of the Committee under the Plan, unless the exercise of such powers and duties by the Board would cause the Plan not to comply with the requirements of Rule 16b-3 or applicable law or exchange requirements.

Section 4.    Shares Available for Awards.

(a)    Shares Available. Subject to adjustment as provided in Section 4(c) of the Plan, the aggregate number of Shares that may be issued under all Awards under the Plan shall equal 2,950,000. The aggregate number of Shares that may be issued under all Awards under the Plan shall be reduced by Shares subject to Awards issued under the Plan in accordance with the Share counting rules described in Section 4(b) below. On and after shareholder approval of this Plan, no awards shall be granted under the Prior Stock Plan, but all outstanding awards previously granted under the Prior Stock Plan shall remain outstanding and subject to the terms of the Prior Stock Plan.

(b)    Counting Shares. Except as set forth below in this Section 4(b), if an Award entitles the holder thereof to receive or purchase Shares, the number of Shares covered by such Award or to which such Award relates shall be counted on the date of grant of such Award against the aggregate number of Shares available for granting Awards under the Plan.

(i)    Shares Added Back to Reserve. Subject to the limitations in Section 4(b)(ii) below, if any Shares covered by an Award or to which an Award relates are not purchased or are forfeited or are reacquired by the Company, or if an Award otherwise terminates or is cancelled without delivery of any Shares, then the number of Shares counted against the aggregate number of Shares available under the Plan with respect to such Award, to the extent of any such forfeiture, reacquisition by the Company, termination or cancellation, shall again be available for granting Awards under the Plan.

(ii)    Shares Not Added Back to Reserve. Notwithstanding anything to the contrary in Section 4(b)(i) above, the following Shares will not again become available for issuance under the Plan: (A) any Shares which would have been issued upon any exercise of an Option but for the fact that the exercise price was paid by a “net exercise” pursuant to Section 6(a)(iii)(B) or any Shares tendered in payment of the exercise price of an Option; (B) any Shares withheld by the Company or Shares tendered to satisfy any tax withholding obligation with respect to an Award; (C) Shares granted as a stock‑settled Stock Appreciation Right issued under the Plan that are not issued in connection with settlement in Shares upon exercise; or (D) Shares that are repurchased by the Company using Option exercise proceeds.

(iii)    Cash Only Awards. Awards that do not entitle the holder thereof to receive or purchase Shares shall not be counted against the aggregate number of Shares available for Awards under the Plan.

(iv)    Substitute Awards Relating to Acquired Entities. Shares issued under Awards granted in substitution for awards previously granted by an entity that is acquired by or merged with the Company or an Affiliate shall not be counted against the aggregate number of Shares available for Awards under the Plan.

(c)    Adjustments. In the event that any dividend (other than a regular cash dividend) or other distribution (whether in the form of cash, Shares, other securities or other property), recapitalization, stock split, reverse stock split, reorganization, merger, consolidation, split‑up, spin‑off, combination, repurchase or exchange of Shares or other securities of the Company, issuance of warrants or other rights to purchase Shares or other securities of the Company or other similar corporate transaction or event affects the Shares such that an adjustment is necessary in order to prevent dilution or enlargement of the benefits or potential benefits intended to be made available under the Plan, then the Committee shall, in such manner as it may deem equitable, adjust any or all of (i) the number and type of Shares (or other securities or other property) that thereafter may be made the subject of Awards, (ii) the number and type of Shares (or other securities or other

102

property) subject to outstanding Awards, (iii) the purchase price or exercise price with respect to any Award and (iv) the limitations contained in Section 4(d) below; provided, however, that the number of Shares covered by any Award or to which such Award relates shall always be rounded down to the nearest whole number. Such adjustment shall be made by the Committee or the Board, whose determination in that respect shall be final, binding and conclusive.

(d)    Annual Limitation on Grants of Awards. No Eligible Person who is an employee or officer may be granted any Award or Awards for more than 200,000 Shares (subject to adjustment as provided for in Section 4(c) of the Plan), in the aggregate in any calendar year. No Eligible Person who is a consultant or independent contractor may be granted any Award or Awards for more than 30,000 Shares (subject to adjustment as provided for in Section 4(c) of the Plan), in the aggregate in any calendar year.

Section 5.    Eligibility.

Any Eligible Person, including any Eligible Person who is an officer of the Company or any Affiliate, shall be eligible to be designated a Participant. In determining which Eligible Persons shall receive an Award and the terms of any Award, the Committee may take into account the nature of the services rendered by the respective Eligible Persons, their present and potential contributions to the success of the Company, previous Awards received by such Eligible Person (whether under the Plan or a predecessor plan of the Company), or such other factors as the Committee, in its discretion, shall deem relevant. Notwithstanding the foregoing, an Incentive Stock Option may only be granted to full-time or part‑time employees (which term as used herein includes, without limitation, officers), and an Incentive Stock Option shall not be granted to an employee of an Affiliate unless such Affiliate is also a “subsidiary corporation” of the Company within the meaning of Section 424(f) of the Code or any successor provision.

Section 6.    Awards.

(a)    Options. The Committee is hereby authorized to grant Options to Eligible Persons with the following terms and conditions and with such additional terms and conditions not inconsistent with the provisions of the Plan as the Committee shall determine:

(i)    Exercise Price. The exercise price per Share exercisable under an Option shall be determined by the Committee and shall not be less than one hundred percent (100%) of the Fair Market Value of a Share on the date of grant of such Option; provided, however, that the Committee may designate an exercise price below Fair Market Value on the date of grant if the Option is granted in substitution for a stock option previously granted by an entity that is acquired by or merged with the Company or an Affiliate.

(ii)    Option Term. The term of each Option shall be fixed by the Committee but shall not be longer than ten (10) years from the date of grant.

(iii)    Time and Method of Exercise. The Committee shall determine the time or times at which an Option may be exercised within the Option term, either in whole or in part, and the method of exercise, except that any exercise price tendered shall be in either cash, Shares or combination thereof having a Fair Market Value on the exercise date equal to the applicable exercise price, as determined by the Committee.

(A)    Promissory Notes. For avoidance of doubt, the Committee may not accept a promissory note as consideration.

(B)    Net Exercises. The terms of any Option may be written to permit the Option to be exercised by delivering to the Participant a number of Shares having an aggregate Fair Market Value (determined as of the date of exercise) equal to the excess, if any, of the Fair Market Value of the Shares underlying the Option being exercised, on the date of exercise, over the exercise price of the Option for such Shares.

(iv)    Incentive Stock Options. Notwithstanding anything in the Plan to the contrary, the following additional provisions shall apply to the grant of stock options which are intended to qualify as Incentive Stock Options:

103

(A)    The Committee will not grant Incentive Stock Options in which the aggregate Fair Market Value (determined as of the time the Option is granted) of the Shares with respect to which Incentive Stock Options are exercisable for the first time by any Participant during any calendar year (under this Plan and all other plans of the Company and its Affiliates) shall exceed $100,000.

(B)    All Incentive Stock Options must be granted within ten (10) years from the earlier of the date on which this Plan was adopted by the Board or the date this Plan was approved by the shareholders of the Company.

(C)    Unless sooner exercised, all Incentive Stock Options shall expire and no longer be exercisable no later than ten (10) years after the date of grant; provided, however, that in the case of a grant of an Incentive Stock Option to a Participant who, at the time such Option is granted, owns (within the meaning of Section 422 of the Code) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of its Affiliates, such Incentive Stock Option shall expire and no longer be exercisable no later than five (5) years from the date of grant.

(D)    The exercise price per Share for an Incentive Stock Option shall be not less than one hundred percent (100%) of the Fair Market Value of a Share on the date of grant of the Incentive Stock Option; provided, however, that, in the case of the grant of an Incentive Stock Option to a Participant who, at the time such Option is granted, owns (within the meaning of Section 422 of the Code) stock possessing more than ten percent (10%) of the total combined voting power of all classes of stock of the Company or of its Affiliates, the exercise price per Share exercisable under an Incentive Stock Option shall be not less than one hundred ten percent (110%) of the Fair Market Value of a Share on the date of grant of the Incentive Stock Option.

(b)    Stock Appreciation Rights. The Committee is hereby authorized to grant Stock Appreciation Rights to Eligible Persons subject to the terms of the Plan and any applicable Award Agreement. A Stock Appreciation Right granted under the Plan shall confer on the holder thereof a right to receive upon exercise thereof the excess of (i) the Fair Market Value of one Share on the date of exercise over (ii) the grant price of the Stock Appreciation Right as specified by the Committee, which price shall not be less than one hundred percent (100%) of the Fair Market Value of one Share on the date of grant of the Stock Appreciation Right; provided, however, that the Committee may designate a grant price below Fair Market Value on the date of grant if the Stock Appreciation Right is granted in substitution for a stock appreciation right previously granted by an entity that is acquired by or merged with the Company or an Affiliate. Subject to the terms of the Plan and any applicable Award Agreement, the grant price, term, methods of exercise, dates of exercise, methods of settlement and any other terms and conditions of any Stock Appreciation Right shall be as determined by the Committee (except that the term of each Stock Appreciation Right shall be subject to the ten (10) year maximum term in Section 6(a)(ii) applicable to Options). The Committee may impose such conditions or restrictions on the exercise of any Stock Appreciation Right as it may deem appropriate.

(c)    Restricted Stock and Restricted Stock Units. The Committee is hereby authorized to grant Awards of Restricted Stock and Restricted Stock Units to Eligible Persons with the following terms and conditions and with such additional terms and conditions not inconsistent with the provisions of the Plan as the Committee shall determine:

(i)    Restrictions. Shares of Restricted Stock and Restricted Stock Units shall be subject to such restrictions as the Committee may impose (including, without limitation, any limitation on the right to vote a Share of Restricted Stock or the right to receive any dividend or other right or property with respect thereto), which restrictions may lapse separately or in combination at such time or times, in such installments or otherwise as the Committee may deem appropriate. Vesting of such Awards may, at the Committee’s discretion, be conditioned upon the Participant’s completion of a minimum period of service with the Company or an Affiliate, or upon the achievement of one or more performance goals established by the Committee, or upon any combination of service-based and performance-based conditions, subject to the minimum vesting requirements in Section 6(f). Notwithstanding the foregoing, rights to dividend or Dividend Equivalent payments shall be subject to the limitations described in Section 6(d).

(ii)    Issuance and Delivery of Shares. Any Restricted Stock granted under the Plan shall be issued at the time such Awards are granted and may be evidenced in such manner as the Committee

104

may deem appropriate, including book‑entry registration or issuance of a stock certificate or certificates, which certificate or certificates shall be held by the Company or held in nominee name by the stock transfer agent or brokerage service selected by the Company to provide such services for the Plan. Such certificate or certificates shall be registered in the name of the Participant and shall bear an appropriate legend referring to the restrictions applicable to such Restricted Stock. Shares representing Restricted Stock that are no longer subject to restrictions shall be delivered (including by updating the book‑entry registration) to the Participant promptly after the applicable restrictions lapse or are waived. In the case of Restricted Stock Units, no Shares shall be issued at the time such Awards are granted. Upon the lapse or waiver of restrictions and the restricted period relating to Restricted Stock Units evidencing the right to receive Shares, such Shares shall be issued and delivered to the holder of the Restricted Stock Units.

(d)    Dividend Equivalents. The Committee is hereby authorized to grant Dividend Equivalents to Eligible Persons under which the Participant shall be entitled to receive payments (in cash or Shares as determined in the discretion of the Committee) equivalent to the amount of cash dividends paid by the Company to holders of Shares with respect to a number of Shares determined by the Committee. Subject to the terms of the Plan and any applicable Award Agreement, such Dividend Equivalents may have such terms and conditions as the Committee shall determine. Notwithstanding the foregoing, (i) the Committee may not grant Dividend Equivalents to Eligible Persons in connection with grants of Options, Stock Appreciation Rights or other Awards the value of which is based solely on an increase in the value of the Shares after the grant of such Award, and (ii) dividend and Dividend Equivalent amounts with respect to any Share underlying an Award may be accrued but not paid to a Participant until all conditions or restrictions relating to such Share have been satisfied or lapsed.

(e)    Other Stock‑Based Awards. The Committee is hereby authorized to grant to Eligible Persons such other Awards that are denominated or payable in, valued in whole or in part by reference to, or otherwise based on or related to, Shares (including, without limitation, securities convertible into Shares), as are deemed by the Committee to be consistent with the purpose of the Plan. The Committee shall determine the terms and conditions of such Awards, subject to the terms of the Plan and any applicable Award Agreement. No Award issued under this Section 6(e) shall contain a purchase right or an option like exercise feature.

(f)    General.

(i)    Consideration for Awards. Awards may be granted for no cash consideration or for any cash or other consideration as may be determined by the Committee or required by applicable law.

(ii)    Awards May Be Granted Separately or Together. Awards may, in the discretion of the Committee, be granted either alone or in addition to, in tandem with or in substitution for any other Award or any award granted under any other plan of the Company or any Affiliate. Awards granted in addition to or in tandem with other Awards or in addition to or in tandem with awards granted under any other plan of the Company or any Affiliate may be granted either at the same time as or at a different time from the grant of such other Awards or awards.

(iii)    Limits on Transfer of Awards. No Award (other than fully vested and unrestricted Shares issued pursuant to any Award) and no right under any such Award shall be transferable by a Participant other than by will or by the laws of descent and distribution, and no Award (other than fully vested and unrestricted Shares issued pursuant to any Award) or right under any such Award may be pledged, alienated, attached or otherwise encumbered, and any purported pledge, alienation, attachment or encumbrance thereof shall be void and unenforceable against the Company or any Affiliate. Notwithstanding the foregoing, the Committee may permit the transfer of an Award, other than a fully vested and unrestricted Share, to family members if such transfer is for no value and in accordance with the General Instructions to Form S-8 (or any successor to such Instructions or such Form) under the Securities Act of 1933, as amended. The Committee may also establish procedures as it deems appropriate for a Participant to designate a person or persons, as beneficiary or beneficiaries, to exercise the rights of the Participant and receive any property distributable with respect to any Award in the event of the Participant’s death.

(iv)    Restrictions; Securities Exchange Listing. All Shares or other securities delivered under the Plan pursuant to any Award or the exercise thereof shall be subject to such restrictions as the Committee may deem advisable under the Plan, applicable federal or state securities laws and regulatory

105

requirements, and the Committee may cause appropriate entries to be made or legends to be placed on the certificates for such Shares or other securities to reflect such restrictions. If the Shares or other securities are traded on a securities exchange, the Company shall not be required to deliver any Shares or other securities covered by an Award unless and until such Shares or other securities have been admitted for trading on such securities exchange.

(v)    Prohibition on Option and Stock Appreciation Right Repricing. Except as provided in Section 4(c) hereof, the Committee may not, without prior approval of the Company’s shareholders, seek to effect any repricing of any previously granted, “underwater” Option or Stock Appreciation Right by: (i) amending or modifying the terms of the Option or Stock Appreciation Right to lower the exercise price; (ii) cancelling the underwater Option or Stock Appreciation Right and granting either (A) replacement Options or Stock Appreciation Rights having a lower exercise price; or (B) Restricted Stock, Restricted Stock Units or Other Stock-Based Award in exchange; or (iii) cancelling or repurchasing the underwater Option or Stock Appreciation Right for cash or other securities. An Option or Stock Appreciation Right will be deemed to be “underwater” at any time when the Fair Market Value of the Shares covered by such Option or Stock Appreciation Right is less than the exercise price.

(vi)    Minimum Vesting. No Award shall be granted with terms providing for any right of exercise or lapse of any vesting obligations earlier than a date that is at least one year following the date of grant (or, in the case of vesting based upon performance-based objectives, exercise and vesting restrictions cannot lapse earlier than the one-year anniversary measured from the commencement of the period over which performance is evaluated); provided, however, that the Award Agreement by its terms may permit acceleration or waiver of the minimum restrictions solely upon the Participant’s death, Disability, Retirement or Qualifying Termination. Notwithstanding the foregoing:

(A)    A maximum of five percent (5%) of the aggregate number of Shares available for issuance under this Plan may be issued as Awards that do not comply with the applicable one-year minimum exercise and vesting requirements and limited exceptions set forth above. For purposes of counting Shares against the five percent (5%) limitation, the Share counting rules under Section 4 of this Plan apply.

(B)    Nothing in this Section 6 shall limit the authority of the Committee to amend or modify any Award to accelerate the vesting or the exercisability of any Award or the lapse of any restrictions relating to any Award (except where expressly limited in Section 6(f)(vii)).

(vii)    Limits on Acceleration or Waiver of Restrictions for Change-in-Control Transactions. No Award Agreement shall, by operation of its terms, accelerate the exercisability of any Award or the lapse of restrictions relating to any Award in connection with a reorganization, merger or consolidation of, or sale or other disposition of all or substantially all of the assets of, the Company unless such transaction constitutes a Change-in-Control and unless such acceleration occurs upon the consummation of (or effective immediately prior to the consummation of, provided that the consummation subsequently occurs) the Change-in-Control.

(viii)    Section 409A Provisions. Notwithstanding anything in the Plan or any Award Agreement to the contrary, to the extent that any amount or benefit that constitutes “deferred compensation” to a Participant under Section 409A and applicable guidance thereunder is otherwise payable or distributable to a Participant under the Plan or any Award Agreement solely by reason of the occurrence of a Change-in-Control or due to the Participant’s disability or “separation from service” (as such term is defined under Section 409A), such amount or benefit will not be payable or distributable to the Participant by reason of such circumstance unless the Committee determines in good faith that (i) the circumstances giving rise to such Change-in-Control, disability or separation from service meet the definition of a change-in-control event, disability, or separation from service, as the case may be, in Section 409A(a)(2)(A) of the Code and applicable proposed or final regulations, or (ii) the payment or distribution of such amount or benefit would be exempt from the application of Section 409A by reason of the short-term deferral exemption or otherwise. Any payment or distribution that otherwise would be made to a Participant who is a Specified Employee (as determined by the Committee in good faith) on account of separation from service may not be made before the date which is six months after the date of the Specified Employee’s separation from service (or if earlier, upon the Specified Employee’s death) unless the payment or distribution is exempt from the application of Section 409A by reason of the short-term deferral exemption or otherwise.

106

Section 7.    Amendment and Termination; Corrections.

(a)    Amendments to the Plan and Awards. The Board may from time to time amend, suspend or terminate this Plan, and the Committee may amend the terms of any previously granted Award, provided that no amendment to the terms of any previously granted Award may (except as expressly provided in the Plan) adversely alter or impair the terms or conditions of the Award previously granted to a Participant under this Plan without the written consent of the Participant or holder thereof. Any amendments to the Plan or an Award that are necessary or desirable to comply with applicable laws, rules, regulations and policies of any applicable governmental entity or stock exchange (including amendments to the Plan or Awards necessary or desirable to maximize any available tax deduction or to avoid any adverse tax results, and no action taken to comply with such laws, rules, regulations and policies shall be deemed to not impair or otherwise adversely alter or impair the rights of any holder of an Award or beneficiary thereof).

(b)    Amendments Requiring Shareholder Approval. For greater certainty and without limiting the foregoing, the Board may amend, suspend, terminate or discontinue the Plan, and the Committee may amend or alter any previously granted Award, as applicable, without obtaining the approval of shareholders of the Company, except that prior approval of the shareholders of the Company shall be required for any amendment to the Plan or an Award that would:

(i)    require shareholder approval under the rules or regulations of the Securities and Exchange Commission, the NASDAQ Global Select Market or any other securities exchange that are applicable to the Company;

(ii)    increase the number of shares authorized under the Plan as specified in Section 4(a) of the Plan;

(iii)    permit repricing of Options or Stock Appreciation Rights, which is currently prohibited by Section 6 of the Plan;

(iv)    permit the award of Options or Stock Appreciation Rights at a price less than one hundred percent (100%) of the Fair Market Value of a Share on the date of grant of such Option or Stock Appreciation Right, contrary to the provisions of Section 6(a)(i) and Section 6(b) of the Plan;

(v)    increase the maximum term permitted for Options and Stock Appreciation Rights as specified in Section 6(a) and Section 6(b); or

In the event of any reorganization, merger, consolidation, split-up, spin-off, combination, plan of arrangement, take-over bid or tender offer, repurchase or exchange of Shares or other securities of the Company or any other similar corporate transaction or event involving the Company (or the Company shall enter into a written agreement to undergo such a transaction or event), the Committee or the Board may provide for any of the following to be effective upon the consummation of the event (or effective immediately prior to the consummation of the event, provided that the consummation of the event subsequently occurs), and no action taken under this Section 7(c) shall be deemed to impair or otherwise adversely alter or impair the rights of any holder of an Award or beneficiary thereof:

(i)    either (A) termination of any Award, whether or not vested, in exchange for an amount of cash and/or other property, if any, equal to the amount that would have been attained upon the exercise of the Award or realization of the Participant’s rights (and, for the avoidance of doubt, if, as of the date of the occurrence of the transaction or event described in this Section 7(c)(i)(A), the Committee or the Board determines in good faith that no amount would have been attained upon the exercise of the Award or realization of the Participant’s rights, then the Award may be terminated by the Company without any payment) or (B) the replacement of the Award with other rights or property selected by the Committee or the Board, in its sole discretion;

107

(ii)    that the Award be assumed by the successor or survivor corporation, or a parent or subsidiary thereof, or shall be substituted for by similar options, rights or awards covering the stock of the successor or survivor corporation, or a parent or subsidiary thereof, with appropriate adjustments as to the number and kind of shares and prices;

(iii)    that the Award shall be exercisable or payable or fully vested with respect to all Shares covered thereby, notwithstanding anything to the contrary in the applicable Award Agreement; or

(iv)    that the Award cannot vest, be exercised or become payable after a date certain in the future, which may be the effective date of the event.

(d)    Correction of Defects, Omissions and Inconsistencies. The Committee may, without prior approval of the shareholders of the Company, correct any defect, supply any omission or reconcile any inconsistency in the Plan or in any Award or Award Agreement in the manner and to the extent it shall deem desirable to implement or maintain the effectiveness of the Plan.

Section 8.    Income Tax Withholding.

In order to comply with all applicable federal, state, local or foreign income tax laws or regulations, the Company may take such action as it deems appropriate to ensure that all applicable federal, state, local or foreign payroll, withholding, income or other taxes, which are the sole and absolute responsibility of a Participant are withheld or collected from such Participant. In order to assist a Participant in paying all or a portion of the applicable taxes to be withheld or collected upon exercise or receipt of (or the lapse of restrictions relating to) an Award, the Committee, in its discretion and subject to such additional terms and conditions as it may adopt, may permit the Participant to satisfy such tax obligation by (a) electing to have the Company withhold a portion of the Shares otherwise to be delivered upon exercise or receipt of (or the lapse of restrictions relating to) such Award with a Fair Market Value equal to the amount of such taxes or (b) delivering to the Company Shares other than Shares issuable upon exercise or receipt of (or the lapse of restrictions relating to) such Award with a Fair Market Value equal to the amount of such taxes. The election, if any, must be made on or before the date that the amount of tax to be withheld is determined.

Section 9.    General Provisions.

(a)    No Rights to Awards. No Eligible Person, Participant or other Person shall have any claim to be granted any Award under the Plan, and there is no obligation for uniformity of treatment of Eligible Persons, Participants or holders or beneficiaries of Awards under the Plan. The terms and conditions of Awards need not be the same with respect to any Participant or with respect to different Participants.

(b)    Award Agreements. No Participant shall have rights under an Award granted to such Participant unless and until an Award Agreement shall have been duly executed on behalf of the Company and, if requested by the Company, signed by the Participant, or until such Award Agreement is delivered and accepted through any electronic medium in accordance with procedures established by the Company.

(c)    No Rights of Shareholders. Except with respect to Shares issued under Awards (and subject to such conditions as the Committee may impose on such Awards pursuant to Section 6(c)(i) or Section 6(d)), neither a Participant nor the Participant’s legal representative shall be, or have any of the rights and privileges of, a shareholder of the Company with respect to any Shares issuable upon the exercise or payment of any Award, in whole or in part, unless and until such Shares have been issued.

(d)    No Limit on Other Compensation Plans or Arrangements. Nothing contained in the Plan shall prevent the Company or any Affiliate from adopting or continuing in effect other or additional compensation plans or arrangements, and such plans or arrangements may be either generally applicable or applicable only in specific cases.

(e)    No Right to Employment. The grant of an Award shall not be construed as giving a Participant the right to be retained as an employee of the Company or any Affiliate, nor will it affect in any way the right of the Company or an Affiliate to terminate a Participant’s employment at any time, with or without cause, in accordance with applicable law. In addition, the Company or an Affiliate may at any time dismiss a

108

Participant from employment free from any liability or any claim under the Plan or any Award, unless otherwise expressly provided in the Plan or in any Award Agreement. Nothing in this Plan shall confer on any person any legal or equitable right against the Company or any Affiliate, directly or indirectly, or give rise to any cause of action at law or in equity against the Company or an Affiliate. Under no circumstances shall any person ceasing to be an employee of the Company or any Affiliate be entitled to any compensation for any loss of any right or benefit under the Plan which such employee might otherwise have enjoyed but for termination of employment, whether such compensation is claimed by way of damages for wrongful or unfair dismissal, breach of contract or otherwise. By participating in the Plan, each Participant shall be deemed to have accepted all the conditions of the Plan and the terms and conditions of any rules and regulations adopted by the Committee and shall be fully bound thereby.

(f)    Governing Law. The validity, construction and effect of the Plan or any Award, and any rules and regulations relating to the Plan or any Award, shall be determined in accordance with the laws of the State of Minnesota.

(g)    Severability. If any provision of the Plan or any Award is or becomes or is deemed to be invalid, illegal or unenforceable in any jurisdiction or would disqualify the Plan or any Award under any law deemed applicable by the Committee, such provision shall be construed or deemed amended to conform to applicable laws, or if it cannot be so construed or deemed amended without, in the determination of the Committee, materially altering the purpose or intent of the Plan or the Award, such provision shall be stricken as to such jurisdiction or Award, and the remainder of the Plan or any such Award shall remain in full force and effect.

(h)    No Trust or Fund Created. Neither the Plan nor any Award shall create or be construed to create a trust or separate fund of any kind or a fiduciary relationship between the Company or any Affiliate and a Participant or any other Person. To the extent that any Person acquires a right to receive payments from the Company or any Affiliate pursuant to an Award, such right shall be no greater than the right of any unsecured general creditor of the Company or any Affiliate.

(i)    No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to the Plan or any Award, and the Committee shall determine whether cash shall be paid in lieu of any fractional Share or whether such fractional Share or any rights thereto shall be cancelled, terminated or otherwise eliminated.

(j)    Headings. Headings are given to the Sections and subsections of the Plan solely as a convenience to facilitate reference. Such headings shall not be deemed in any way material or relevant to the construction or interpretation of the Plan or any provision thereof.

(k)    Other Benefits. No compensation or benefit awarded to or realized by any Participant under the Plan shall be included for the purpose of computing such Participant’s compensation under any compensation‑based retirement, disability, or similar plan of the Company unless required by law or otherwise provided by such other plan.

Section 10.    Clawback or Recoupment.

In addition to such forfeiture and/or penalty conditions as specified in any Award Agreement, Awards under this Plan shall be subject to forfeiture or other penalties pursuant any clawback or similar recoupment policy as may be established or amended from time to time.

Section 11.    Effective Date of the Plan.

The Plan was adopted by the Board on June 26, 2019. The Plan shall be subject to approval by the shareholders of the Company at the annual meeting of shareholders of the Company to be held on January 14, 2020 and the Plan shall be effective as of the date of such shareholder approval. On and after shareholder approval of the Plan, no awards shall be granted under the Prior Stock Plan, but all outstanding awards previously granted under the Prior Stock Plan shall remain outstanding and subject to the terms of the Prior Stock Plan.

109

Section 12.    Term of the Plan.

No Award shall be granted under the Plan, and the Plan shall terminate, on June 26, 2029 or any earlier date of discontinuation or termination established pursuant to Section 7(a) of the Plan. Unless otherwise expressly provided in the Plan or in an applicable Award Agreement, any Award theretofore granted may extend beyond such dates, and the authority of the Committee provided for hereunder with respect to the Plan and any Awards, and the authority of the Board to amend the Plan, shall extend beyond the termination of the Plan.
