Three Class I directors are to be elected at the meeting. The Board of Directors, at its meeting on April 29, 2026, upon the recommendation of the Nominating and Corporate Governance Committee, selected Mr. Thomas D. Hull III, Mr. David S. Rhind, and Mr. John D. Russell as the nominees for re-election as directors at the annual meeting, to serve for a three-year term. The nominees are serving as directors as of the date of this Proxy Statement. The nominees receiving the greatest number of votes at the annual meeting will be elected directors. Unless a stockholder indicates otherwise on the proxy card and the proxy card is validly executed and returned, the stockholder’s shares will be voted for the election of the nominees named below. If due to circumstances not now foreseen, the nominees become unavailable for election, the proxies will be voted for such other person or persons as the Board of Directors may select, or the Board will make an appropriate reduction in the number of directors to be elected.

Information on the current nominees for Class I directors and the current Class II and III directors are shown below.

THOMAS D. HULL III, 50, was elected President and Chief Executive Officer and appointed a member of the Board in March 2019.

Except as otherwise indicated, each director and nominee has had the principal occupation mentioned above for more than five years.

Except for Mr. Hull, each director and nominee is an independent director.

The Board of Directors has a policy whereby any director reaching age 80 during his/her term is expected to retire at the end of the term.

The business and affairs of the Company are managed under the direction of the Board of Directors. Members of the Board keep informed of the Company’s business and activities through reports and proposals sent to them periodically and in advance of each Board meeting and reports made to them during these meetings by the Chief Executive Officer and other Company officers. The Board is regularly advised of actions taken by the committees of the Board, as well as significant actions taken by management. Members of management are available at Board meetings and other times to answer questions and discuss issues. During the Company’s fiscal year ended April 30, 2026, the Board of Directors held seven meetings.

During fiscal year 2026, the standing committees of the Board of Directors of the Company were the Audit Committee, Compensation Committee, Financial/Planning Committee, and Nominating and Corporate Governance Committee. The functions and membership of the committees are described below.

The Audit Committee consists of Messrs. Gehl (Chairman), Russell, Shaw, and Campbell. All members of the committee are independent directors. The committee performs the responsibilities and duties described in the Company’s Audit Committee Charter, and is responsible for annually appointing the independent auditor for the Company, approving services to be performed by the independent auditor, reviewing the independent auditor’s reports, and reviewing the Company’s quarterly and annual financial statements before release to the public. In accordance with Audit Committee Charter guidelines, the committee is responsible for reviewing and approving all related party transactions. The Board of Directors has determined that Messrs. Gehl and Campbell qualify as an “audit committee financial expert” within the meaning of the current rules of the Securities and Exchange Commission (“SEC”). The committee met six times during the Company’s last fiscal year. The Audit Committee Charter can be found on the Company’s website at http://www.kewaunee.com.

The Compensation Committee consists of Messrs. Russell (Chairman), Gehl, Rhind, and Shaw and Ms. Pyle. All members of the committee are independent directors. The committee considers and provides recommendations to the Board of Directors with respect to the compensation (salaries and bonuses) of executive officers of the Company; short- and long-range incentive compensation programs for officers and other key employees of the Company; and equity award grants to key employees. The committee has acted as the plan administrator for the Kewaunee Scientific Corporation 2023 Omnibus Incentive Plan (the “2023 Plan”), as well as prior stock option plans for officers and other key employees. The committee may delegate its responsibilities and authority to one or more subcommittees as the committee may deem appropriate in its sole discretion. The Compensation Committee Charter can be found on the Company’s website at http://www.kewaunee.com. The committee met four times during the Company’s last fiscal year. The committee has engaged a compensation consultant in the past to advise the committee on executive compensation, and did so on a limited basis in 2025 and in 2026.

The Financial/Planning Committee consists of Messrs. Shaw (Chairman), Hull, Russell, Campbell, and Ms. Pyle. The committee reviews and provides recommendations to the Board of Directors with respect to the Company’s strategic plan, the annual budget for the Company, and the annual budget for capital expenditures. The committee also reviews the investment results of the assets of the Company’s retirement plans. The committee met six times during the Company’s last fiscal year.

The Nominating and Corporate Governance Committee consists of Ms. Pyle (Chairwoman), and Messrs. Gehl and Rhind. The committee performs the responsibilities and duties described in the Company’s Nominating and Corporate Governance Committee Charter, which is available on the Company’s website at http://www.kewaunee.com. The committee is comprised of at least three directors, all of whom meet the criteria for independence required by the NASDAQ Global Market. The committee reviews and recommends to the Board of Directors the appointment of directors to Board committees and the selection of the chairperson of each committee, makes recommendations to the Board of Directors with respect to officers of the Company, assures that an up-to-date management succession plan is in place for the Chief Executive Officer and other executive officers, reviews and makes recommendations to the Board of Directors regarding director compensation and benefits, periodically reviews the skills and qualifications of existing directors with a view toward a well-rounded and effective Board, identifies and screens potential nominees to the Board, and reviews stockholder proposals for inclusion in the Company’s Proxy Statement. In addition, the committee makes recommendations to the Board of Directors concerning nominees for Board membership brought to its attention by officers, directors, and stockholders. Proposals may be addressed by the stockholders of the Company to the committee at the address shown on the cover of this Proxy Statement, attention of the Secretary. At a minimum, a candidate for the Board must have demonstrated significant accomplishment in his or her field, the capacity and experience to understand the broad business operations of the Company, and the vision to assist the Company in its development and expansion. The Nominating and Corporate Governance Committee does not favor or disfavor any particular nominee on the basis of race, religion, gender, age, or national origin. The Committee met four times during the Company’s last fiscal year.

Executive sessions of independent directors are held as necessary. The Board of Directors’ policy is to hold executive sessions without the presence of management, including the Chief Executive Officer and any other non-independent directors. The Board of Directors has determined that each of Messrs. Gehl, Rhind, Russell, Shaw, Campbell, and Ms. Pyle are independent within the meaning of the rules of the NASDAQ Global Market.

The Company does not have a formal policy regarding attendance by members of the Board of Directors at the Annual Meeting of Stockholders, although all directors are expected to attend. All members of the Board of Directors attended the Company’s 2025 Annual Meeting of Stockholders. In the Company’s last fiscal year, each director attended, personally or via teleconference, at least 75% of the aggregate number of meetings of the Board and committees on which such director served during the period in which he or she served as a director during fiscal 2026. Mr. Campbell was appointed to the Board on September 10, 2025.

The Board determines whether the role of the Chairman and the Chief Executive Officer should be separated or combined based on its judgment as to the structure that best serves the interests of the Company and its stockholders. Currently, the Board believes that the positions of Chairman and Chief Executive Officer should be separate.

The Board oversees risk management processes directly and through its committees. Management is responsible for risk management on a day-to-day basis. The role of the Board and its committees is to oversee the risk management activities of management. The Audit Committee assists the Board in fulfilling its oversight responsibilities with respect to risk management in the areas of financial reporting, internal controls, cybersecurity, and compliance with legal and regulatory requirements. The Compensation Committee assists the Board in fulfilling its oversight responsibilities with respect to the management of risk arising from our compensation policies and programs. The Nominating and Corporate Governance Committee assists the Board in fulfilling its oversight responsibilities with respect to the management of risks associated with Board organization, membership and structure, and succession planning for our directors.

The Board of Directors recommends that any communications from stockholders be in writing and addressed to the Board in care of the Corporate Secretary, 2700 West Front Street, Statesville, North Carolina 28677-2927. The name of any specific Board member to whom a communication is intended to be addressed should be noted in the communication. The Corporate Secretary will forward such correspondence only to the intended recipient if one is noted; however, the Corporate Secretary, prior to forwarding any correspondence, will review the correspondence, and in his discretion, will not forward certain items if they are deemed frivolous, of inconsequential commercial value, or otherwise inappropriate for Board consideration.

As noted above, the Compensation Committee consists of Messrs. Russell, Gehl, Rhind, and Shaw and Ms. Pyle. No executive officer of the Company served as a member of the Compensation Committee or as a director of any other entity, one of whose executive officers serves on the Compensation Committee or is a director of the Company.

In fiscal year 2026, each non-employee director of the Company received an annual retainer of $120,000. For fiscal year 2026, the annual retainer was payable half in cash ($60,000), payable monthly over the last six months of the fiscal year, and half in fully vested shares of Company common stock ($60,000, with the number of shares based on the average of the high price and low price of the common stock on the grant date, which is generally in early May), except that directors who have satisfied the Company’s stock ownership guidelines could elect to receive $60,000 in cash in lieu of stock. In addition, the Chairs of the Nominating and Corporate Governance Committee, Financial/Planning Committee, and Compensation Committee each received an annual cash fee of $10,000; the Chair of the Audit Committee received an annual cash fee of $15,000; and the non-employee Chair of the Board received an annual cash fee of $35,000. Directors were also reimbursed for their expenses for each Board and committee meeting attended.

The following table sets forth fiscal year 2026 compensation for each non-employee director of the Company who served during fiscal year 2026. During the year, Mr. Hull served as an employee director of the Company and received no additional compensation for his services as a director. See the Summary Compensation Table for disclosure related to the compensation received by Mr. Hull.

We have adopted a code of ethics that applies to our Chief Executive Officer, Chief Financial Officer and key employees with financial reporting responsibilities (“Code of Ethics”). The Code of Ethics is posted on our website at www.kewaunee.com. We have also adopted a substantially similar code of ethics that applies to officers and key employees. Any waiver or amendment to the Code of Ethics will be timely disclosed on our website. We also make these materials available in print to any stockholder upon request. The Board regularly reviews corporate governance developments and modifies the Code of Ethics as warranted.

We maintain a compliance and ethics hotline through which employees can report evidence of illegal or unethical behavior, or violations of the Code of Ethics. The compliance and ethics hotline is serviced by an independent company, is available seven days a week, 24 hours a day and can be accessed by individuals through a toll-free number. Employees can report concerns anonymously. We maintain a formal no retaliation policy that prohibits retaliation against, or discipline of, an employee who raises an ethical concern in good faith. This system documents the reporting person’s statement and transmits the information to the appropriate Board or management personnel with oversight of the area identified in the report. Those personnel have the authority to conduct an investigation, research applicable policies, regulations, and statutes, and determine the appropriate action to resolve the reported item.

Effective March 1, 2017, the Board approved stock ownership guidelines under which non-employee directors of the Company are expected to maintain ownership of a minimum amount of Company common stock equal in value to three times their annual retainer. Once this requirement has been met, the director can elect to receive cash compensation in lieu of compensation that would otherwise be paid in the form of equity.

In June 2025, the Board amended the stock ownership guidelines for the Company’s executive officers. Under the guidelines, the Chief Executive Officer must maintain ownership of a minimum amount of Company common stock equal in value to 300% of his annual salary, including outstanding shares owned, as well as the value of shares

underlying unvested equity awards subject to a service component. The Chief Financial Officer must maintain ownership of a minimum amount of Company common stock equal in value to 200% of his annual salary, including outstanding shares owned, as well as the value of shares underlying unvested equity awards subject to a service component. All other executive officers must maintain ownership of a minimum amount of Company stock equal in value to 150% of their annual salary, including outstanding shares owned, as well as the value of shares underlying unvested equity awards subject to a service component. The per share value is calculated as a trailing 12-month equal weighted daily average for all officers.

The Company does not have a policy specifically prohibiting employees or directors from engaging in hedging transactions relating to the Company’s securities.

We have adopted an insider trading policy and related procedures governing the purchase, sale, or other dispositions of our securities by our directors, officers and employees, that are reasonably designed to promote compliance with insider trading laws, rules and regulations, and Nasdaq listing standards. A copy of our insider trading policy has been filed as an exhibit to our Annual Report on Form 10-K for our fiscal year ended April 30, 2026.

The Audit Committee has approved the engagement of FORVIS MAZARS, LLP (“FORVIS”), as its independent registered public accounting firm for the fiscal year ending April 30, 2027.

Although not required by law, our bylaws, or otherwise to submit the appointment to a vote by stockholders, the Audit Committee is requesting that the stockholders ratify the appointment of FORVIS because we value our stockholders’ views on our independent public accounting firm and as a matter of good corporate practice. Assuming that a quorum is present, the selection of FORVIS will be deemed to have been ratified if more shares are voted in favor of ratification than are voted against ratification or abstain. The Audit Committee will consider the outcome of this vote but is not bound by our stockholders’ vote.

It is expected that a representative of FORVIS will participate in the virtual Annual Meeting of Stockholders to be held on August 26, 2026 to answer any appropriate questions and such representative will have an opportunity to make a statement if he or she desires.

The Audit Committee’s policy is to pre-approve all audit and non-audit services to be provided by the Company’s independent auditors on a case-by-case basis. In making such determination, the Audit Committee considers whether the provision of non-audit services is compatible with maintaining the auditor’s independence. All of the audit and non-audit services provided by the Company’s independent auditors on behalf of the Company in fiscal years 2026 and 2025 were pre-approved in accordance with this policy.

The following fees were paid or will be paid to Forvis Mazars, LLP for professional services rendered on behalf of the Company related to the past two fiscal years:

For both 2026 and 2025, audit fees included the audit of the Company’s annual consolidated financial statements and the review of its quarterly financial statements. Audit related fees for 2026 included due diligence procedures associated with potential strategic transaction opportunities, as well as services performed in connection with the Company’s preparation for compliance with Section 404(b) of the Sarbanes-Oxley Act. All Other Fees for 2026 consisted primarily of fees for research services performed in connection with the Company’s evaluation of strategic business opportunities. Audit related fees for 2025 included due diligence procedures associated with the acquisition, as well as audits of Nu Aire, Inc.’s financial statements required for inclusion in the Company’s Form 8-K. For additional information related to the acquisition, refer to Note 4 to the Consolidated Financial Statements in the Company’s 2026 Annual Report on Form 10-K.

The Audit Committee is responsible for overseeing the Company’s financial reporting process and other duties as described in the Audit Committee Charter. In fulfilling its oversight responsibilities, the Committee has reviewed and discussed the Company’s audited financial statements for the fiscal year ended April 30, 2026 with management and the Company’s registered independent public accounting firm. Management of the Company is responsible for these financial statements and the Company’s financial reporting process, including the Company’s system of internal

controls. The independent auditors are responsible for expressing an opinion on the conformity of these financial statements with accounting principles generally accepted in the United States. The Committee has discussed with the independent auditors the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. The Committee has received the written disclosures and the letter from Forvis Mazars, LLP required by the applicable requirements of the Public Company Accounting Oversight Board and has discussed with Forvis Mazars, LLP their independence.

The Audit Committee also considered whether the provision of non-audit services by Forvis Mazars LLP, if any, was compatible with maintaining its independence. Based on the Committee’s review of the audited financial statements and the review and discussions described in the preceding paragraph, the Committee recommended to the Board of Directors that the audited financial statements for the fiscal year ended April 30, 2026 be included in the Company’s Annual Report on Form 10-K for the fiscal year ended April 30, 2026 for filing with the SEC. All members of the committee meet the independence standards established by the NASDAQ Global Market.

We are required to submit a proposal to stockholders for a (non-binding) advisory vote to approve the compensation of our named executive officers pursuant to Section 14A of the Securities Exchange Act of 1934, as amended (“Exchange Act”). At our Annual Meeting of Stockholders held in August 2025, we conducted our annual advisory “say-on-pay” vote on the compensation of our named executive officers for fiscal 2025. Excluding abstentions, this proposal received the support of approximately 93% of the votes cast. When abstentions were taken into account, the proposal received the support of approximately 80% of the votes cast. In light of these results, and consistent with our commitment to maintaining a constructive dialogue with our investors, the Company solicited feedback from its stockholders as part of our regular stockholder engagement efforts regarding any views they may have had on our named executive officer compensation program. The Company met with approximately 38.5% of its stockholders (based on the shares outstanding as of June 29, 2026), and we were encouraged that, throughout the course of these discussions, our stockholders did not raise any significant or material objections to the structure, design, or philosophy of the Company’s named executive officer compensation program.

The next stockholder vote on the frequency of holding the advisory vote on executive compensation will be held at the 2031 Annual Meeting. This advisory proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on the compensation of our named executive officers. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the principles, policies, and practices described in this Proxy Statement. Accordingly, the following resolution is submitted for stockholder vote at the 2026 Annual Meeting:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the SEC, including the Compensation Overview, compensation tables, and any related material disclosed in this Proxy Statement, is hereby APPROVED.”

As this is an advisory vote, the result will not be binding on us, the Board of Directors, or the Compensation Committee, although the Board of Directors and the Compensation Committee will consider the outcome of the vote when evaluating our compensation principles, design, and practices. Proxies submitted without direction pursuant to this solicitation will be voted “FOR” the approval of the compensation of our named executive officers, as disclosed in this Proxy Statement.

The following sections provide compensation information pursuant to the scaled disclosure rules applicable to “smaller reporting companies” under the rules of the SEC.

This Compensation Overview describes and explains the compensation awarded to, earned by, or paid to the named executive officers listed below (the “named executive officers”) under the executive compensation program in effect for fiscal year 2026.

Management has successfully navigated several challenging years, executing multiple strategic initiatives to transform and reposition the Company. These initiatives include expanding the Company’s international presence, investing in manufacturing and operational capabilities, strengthening the corporate platform, and acquiring and integrating Nu Aire to broaden the Company’s laboratory products portfolio and enhance its long-term growth opportunities.

Key to this strategy is the retention and recruitment of qualified directors and executives.

Our executive compensation program for the named executive officers is designed to:

The principal components of the Company’s compensation program for named executive officers are discussed below. Executive compensation is overseen by the Compensation Committee of the Board, which is composed solely of independent directors.

The Compensation Committee annually reviews the base salaries of executive officers. Prior to the meeting at which the annual review occurs, the Committee is provided (1) information furnished by the Company’s human resources department on historical data about the base and total compensation for each executive, and marketplace compensation data, including both base and incentive compensation data, for comparable positions at other manufacturing and service companies with generally similar annual sales volume, and (2) individual performance appraisals and recommended base salary adjustments from the Chief Executive Officer for each executive officer, except himself. The human resources department also provides a base salary range based on class for each executive officer, which shows a minimum, mid-point, and maximum salary, and the position of the executive officer’s base salary in this range. The base salary range is established using marketplace comparison data and the individual responsibilities of the executive officer’s position, and is updated each year for inflation. The Company typically targets base salaries at the mid-point of the Company’s established range for a position. The Committee further considers, on a subjective basis, the executive officer’s particular qualifications, level of experience, and sustained performance over time. These same factors are also considered in determining an adjustment to the salary of the Chief Executive Officer. Base salaries are traditionally adjusted as of July 1 of each year. The table below provides annualized information for the base salaries of our named executive officers as of July 1 of the indicated fiscal years.

All of the Company’s executive officers are eligible to participate in an annual incentive bonus plan, pursuant to which each executive officer is eligible to earn a cash and/or equity bonus for each fiscal year of the Company, based on the attainment of financial and non-financial performance goals established under the annual incentive bonus plan and, to a lesser extent, the executive officer’s achievement of established individual objectives, as determined by the Board upon the recommendation of the Chief Executive Officer and the Compensation Committee. Bonuses under the annual incentive plan represent at-risk compensation, that is contingent upon the achievement of specified performance goals.

At the beginning of the fiscal year, the Board approved financial goals for the Company for the year and, upon recommendation of the Compensation Committee, established specified percentages of each executive officer’s base salary that would be available for bonuses if the Company and/or its operating businesses achieved specified financial goals. The Board generally attempted to establish annual goals at target levels it believed were challenging, but achievable, with earnings above target levels considered to be relatively difficult to achieve. In determining the level of available bonuses for each executive officer, many of the same factors considered in determining an executive officer’s base salary were also considered by the Compensation Committee and the Board. The components of the financial goals were achievement of certain predetermined EBITDA targets. EBITDA is a non-GAAP financial measure and is calculated as net earnings (loss), less interest expense and interest income, income taxes, depreciation and amortization.

For fiscal year 2026, annual incentive bonus opportunities were based on both financial and non-financial performance objectives. The financial objective represented 80% of the target bonus opportunity and was subject to threshold, target and maximum performance levels. No payout was earned with respect to the financial component unless the established threshold level of financial performance was achieved. At threshold performance, 50% of the financial component was earned, with payouts between threshold, target and maximum determined on a pro rata basis. The remaining 20% of the target bonus opportunity was based on the achievement of non-financial performance objectives. Accordingly, the overall annual incentive plan provided for payout opportunities ranging from 20% of the target bonus opportunity (if only the non-financial performance objectives were achieved) to 220% of the target bonus opportunity (if all performance objectives, including maximum financial performance, were achieved).

For fiscal year 2026, the Chief Executive Officer’s target bonus opportunity was 80% of annual base salary, with a maximum opportunity equal to 176% of annual based salary. The corresponding target bonus opportunities for Mr. Gardner and Mr. Batdorff were 50% and 45% of annual base salary, respectively, with maximum opportunities equal to 110% and 99% of annual base salary.

The financial and non-financial goals for fiscal year 2026 were achieved, and as a result all of our named executive officers earned a cash bonus for fiscal year 2026 under the annual incentive bonus plan. The amounts of the cash bonuses received by our named executive officers are included in the Summary Compensation Table under the heading “Nonequity Incentive Plan Compensation”.

At the Company’s Annual Meeting of Stockholders held on August 23, 2023, the Company’s stockholders approved the 2023 Plan, and the 2023 Plan became effective at that time. With the effectiveness of the 2023 Plan, no additional equity awards will be granted under the 2017 Plan, although outstanding awards under the 2017 Plan will continue to be administered. Executives are eligible to receive long-term incentive compensation in the form of restricted stock units (“RSUs”). RSUs represent the right to receive, upon vesting of the RSUs, shares of the Company’s common stock. The Company has in the past awarded RSUs with time-based and performance-based vesting conditions. For fiscal year 2026, the time-based RSUs represented 50% of each award and vest in equal annual installments over a three-year period. The performance-based RSUs represent the remaining 50% of the award, assuming target-level achievement, and vest at the end of a three-year performance period based on the Company’s achievement of a predetermined cumulative three-year EBITDA target established by the Compensation Committee. Future awards may contain either time-based or performance-based conditions, or a combination thereof. We currently intend that awards will be made annually, with a new three-year vesting period applicable to each year’s awards. The number of shares covered by the award, assuming target level achievement, is based on a percentage of salary with the percentages for the Mr. Hull, Mr. Gardner and Mr. Batdorff being 190%, 90% and 60%, respectively, and using the average of the high price and low price of our stock price on the grant date to value the awards.

The Company also maintains a 401(k) Incentive Savings Plan (the “401(k) Plan”), which covers substantially all salaried and hourly employees, including all of the executive officers. The 401(k) Plan provides benefits to all employees who have attained age 21, completed three months of service, and elect to participate. Under the terms of the 401(k) Plan, the Company makes matching contributions equal to 100% of the employee’s qualifying contribution up to 3% of the employee’s compensation, and makes matching contributions equal to 50% of the employee’s contributions between 3% and 5% of the employee’s compensation, resulting in a maximum employer contribution equal to 4% of the employee’s compensation. Additionally, the Company may make a discretionary contribution for participants employed by the Company on December 31 of each year up to 1% of the participant’s qualifying compensation for that calendar year based on the profitability of the Company.

The Company also maintains a non-qualified 401 Plus Executive Deferred Compensation Plan (the “401 Plus Plan”), which supplements the 401(k) Plan. The 401 Plus Plan was adopted to provide highly compensated employees an alternative retirement plan because income tax laws restrict the amount of contributions executives may otherwise contribute to the 401(k) Plan. The 401 Plus Plan operates similarly to the 401(k) Plan; the Company makes matching credits to the participant’s account in an amount equal to 50% of the compensation deferred by the participant up to 6% of the participant’s compensation. Amounts deferred under the 401 Plus Plan will be distributed to the participant after the participant’s termination of employment with the Company in cash in a lump sum or installments at a time previously elected by the participant. All of the named executive officers are eligible to participate in the 401(k) plan and the 401 Plus Plan and participated in the 401(k) Plan and the 401 Plus Plan in fiscal year 2026. The 401 Plus Plan allows participants to invest deferred amounts in various standard mutual funds.

Each of the Company’s executive officers is entitled to receive additional compensation in the form of payments, allocations, or accruals under various other group compensation and benefit plans on the same basis as other employees. Benefits under these plans are not directly tied to employee or Company performance.

The Compensation Committee considers the Chief Executive Officer’s leadership an important factor in the future success of the Company. The compensation of the Chief Executive Officer has traditionally included base salary, annual incentive compensation, long-term incentive compensation, and benefits under various group plans. In establishing the Chief Executive Officer’s base salary for each fiscal year, the Compensation Committee considers operating results for the prior year and the outlook for the current year, continued development of the management team, operational improvements, compensation of chief executive officers of other companies with comparable sales, a review of his base salary in relation to the range for his position proposed by the human resources department, and the price of the Company’s common stock.

The Chief Executive Officer’s annual incentive compensation and long-term incentive compensation have been determined pursuant to the Company’s incentive plans for executive officers, and will continue to be determined under the incentive plans for executive officers that are part of the Company’s executive compensation program. Mr. Hull earned a cash bonus of $394,967 for fiscal year 2026 under the annual incentive bonus plan.

The following discussion describes the estimated amount of payments and other benefits that each named executive officer would receive if his employment with the Company was terminated on April 30, 2026.

The Company entered into Change of Control Employment Agreements (i) with Mr. Hull as of November 2, 2015; (ii) with Donald T. Gardner, III, Vice President - Finance, Chief Financial Officer, Treasurer and Secretary in fiscal year 2020; and (iii) with Douglas Batdorff, Vice President of Manufacturing, in fiscal year 2021 (collectively, the “Agreements”). These Agreements provide for the payment of compensation and benefits in the event of termination of the executive officer’s employment within three years following a Change of Control of the Company, as defined in the Agreements. Each executive officer whose employment is so terminated will receive compensation if the termination of his or her employment was by the Company or its successor without Cause, or by the executive officer for Good Reason, each as described below and defined in the Agreements. Upon such a termination of employment within one year following a Change of Control (two years in the case of Mr. Hull and Mr. Gardner), the Company or its successor will be required to make, in addition to unpaid ordinary compensation and a lump-sum cash payment for certain benefits, a lump-sum cash payment equal to the executive officer’s annual compensation (including Annual Salary and Annual Bonus, each as defined in the Agreements), with respect to Mr. Batdorff, and two times the executive officer’s annual compensation with respect to Messrs. Hull and Gardner. Upon a termination of employment occurring after the first anniversary (second anniversary in the case of Messrs. Hull and Gardner), but within three years, of the date of the Change of Control, in addition to unpaid ordinary compensation and a lump-sum cash payment for certain benefits, Mr. Batdorff will be entitled to a lump-sum payment equal to one-half of their annual compensation and Messrs. Hull and Gardner will be entitled to a lump-sum payment equal to their annual compensation. See “Compensation Tables – Payments upon Termination or Change in Control” for other entitlements for the named executive officers under terms of the Agreements. For purposes of the Agreements, subject in each case to certain conditions and qualifications set forth in the Agreements, (A) “Cause” shall mean, (i) the willful and continued failure of the executive officer to perform substantially his or her duties with the Company or one of its affiliates, or (ii) the willful engaging by the executive officer in illegal conduct or gross misconduct which is materially and demonstrably injurious to the Company, and (B) “Good Reason” shall mean, (i) the assignment to the executive officer of any duties inconsistent in any material respect with the executive officer’s position, authority, duties or responsibilities, or any other action by the Company which results in a diminution in such position, authority, duties or responsibilities, (ii) any failure by the Company to comply with any of the compensation provisions of the executive officer’s Agreement, (iii) the Company’s requiring the executive officer to relocate or the Company’s requiring the executive officer without the executive officer’s consent to travel on Company business to a substantially greater extent than required immediately prior to the Change of Control Date, (iv) any purported termination by the Company of the executive officer’s employment otherwise than as expressly permitted by the executive officer’s Agreement, or (v) any failure by the Company to cause any successor to the Company to assume the executive officer’s Agreement.

As described in greater detail in the Compensation Discussion and Analysis section and the executive compensation tables contained in this Proxy Statement, the Company’s executive compensation program reflects a pay-for-performance philosophy. While the Company utilizes several performance measures to align executive compensation with Company performance (as described in greater detail in the Compensation Discussion and Analysis section and the executive compensation tables contained in this Proxy Statement), not all of those Company measures are presented in the Pay versus Performance table. Moreover, the Company generally seeks to incentivize long-term performance, and therefore does not specifically align the Company’s performance measures with compensation that is actually paid (as computed in accordance with Item 402(v) of Regulation S-K) for a particular fiscal year. Compensation actually paid is influenced by numerous factors, including but not limited to the timing of new grant issuances and outstanding grant vesting, share price volatility during the fiscal year, our mix of short-term and long-term metrics, and many other factors. In accordance with Item 402(v) of Regulation S-K, the Company is providing the following descriptions of the relationships between information presented in the Pay versus Performance table.

The following table contains information with respect to the “beneficial ownership” (as defined by the SEC) of shares of the Company’s common stock, as of May 22, 2026, by (i) each director and director nominee, (ii) each of the named executive officers and (iii) all directors and executive officers as a group. Except as otherwise indicated by footnote, the shares shown are held directly with sole voting and investment power.

The following table contains information with respect to the “beneficial ownership” (as defined by the SEC) of shares of the Company’s common stock, as of May 22, 2026, by each person who is known by management of the Company to have been the “beneficial owner” of more than five percent of such stock as of such date. Except as otherwise indicated by footnote, the shares shown are held with sole voting and investment power.

The expense of solicitation of proxies is to be paid by the Company. The Company will also reimburse brokerage houses and other custodians, nominees, and fiduciaries for their reasonable expenses in sending proxies and proxy material to the beneficial owners of the Company’s common stock. This Proxy Statement and the 2026 Annual Report to Stockholders are available at www.proxyvote.com.

At the close of business on June 29, 2026, the record date for determination of stockholders entitled to vote at the annual meeting, there were 2,868,511 shares of common stock of the Company outstanding and entitled to vote.

Each share of common stock is entitled to one vote. Any stockholder giving a proxy has the power to revoke it at any time before it is voted, by written notice to the Secretary, by delivery of a later-dated proxy or by attending and voting at the meeting online.

The holders of a majority of the total shares of common stock issued and outstanding, whether present in person or represented by proxy, will constitute a quorum for the transaction of business at the meeting. The vote of a plurality of the shares represented at the meeting, in person or by proxy, is required to elect the nominees for director. Approval of Item 2 (ratification of appointment of independent registered public accounting firm) and Item 3 (advisory vote on the compensation of our named executives) each requires the affirmative vote of the holders of a majority of the shares of common stock represented at the meeting, in person or by proxy, and entitled to vote. However, Item 3 is an advisory vote only. Abstentions, directions to withhold authority and broker non-votes are counted as shares present in the determination of whether the shares of stock represented at the meeting constitute a quorum. Abstentions are counted in tabulations of votes cast on proposals presented to stockholders other than elections of directors. Directions to withhold authority and broker non-votes are not counted in tabulations of the votes cast on proposals presented to stockholders. Thus, an abstention with respect to a matter other than the election of directors may have the same legal effect as a vote against the matter. Directions to withhold authority and broker non-votes will have no effect on any of the matters to be voted on. An automated system administered by the Company’s transfer agent will be used to tabulate votes.

A stockholder entitled to vote for the election of directors can withhold authority to vote for any of the nominees.

The deadline for receipt of stockholder proposals for inclusion in the Company’s 2027 proxy material is March 9, 2027. Any stockholder proposal should be submitted in writing to the Secretary of the Company at its principal executive offices. The stockholder proposal must include the stockholder’s name and address as it appears on the Company’s records and the number of shares of the Company’s common stock beneficially owned by such stockholder. In addition, (i) for proposals other than nominations for the election of directors, such notice must include a description of the business desired to be brought before the meeting, the reasons for presenting such business at the meeting, and any material interest of the stockholder in such business, and (ii) for proposals relating to stockholder nominations for the election of directors, such notice must also include, with respect to each person nominated, the information required by Regulation 14A under the Exchange Act. All other proposals to be presented at the meeting must be delivered to the Secretary of the Company, in writing, by May 22, 2027.

In addition to satisfying the requirements described above, stockholders who intend to solicit proxies in connection with the 2027 Annual Meeting in support of director nominees other than the Company’s nominees must provide notice that sets forth the information required by Rule 14a-19 under the Exchange Act to comply with the universal proxy rules, which notice must be postmarked or transmitted electronically to the Company at its principal executive offices no later than 60 calendar days prior to the anniversary date of the 2026 Annual Meeting. However, if the date of the 2027 Annual Meeting is changed by more than 30 calendar days from such anniversary date of the 2026 Annual Meeting, then notice must be provided by the later of 60 calendar days prior to the date of the 2027 Annual Meeting or the 10th calendar day following the day on which public announcement of the date of the 2027 Annual Meeting is first made.

The Company’s Annual Report to Stockholders for the fiscal year ended April 30, 2026 is available at www.proxyvote.com. Stockholders are referred to the report for financial and other information about the Company, but such report is not incorporated in this Proxy Statement and is not a part of the proxy soliciting material.

Management of the Company knows of no other matters which are likely to be brought before the annual meeting. If any such matters are brought before the meeting, the persons named in the proxy that accompanies this Proxy Statement will vote thereon according to their judgment.
