ESCO Technologies (NYSE: ESE) details record 2025 results and 2026 proxy votes

Rhea-AI Filing Summary

ESCO Technologies Inc. (NYSE: ESE) is asking shareholders to vote at its 2026 Annual Meeting on January 30, 2026 on four items: electing three directors, an advisory Say‑on‑Pay vote on executive compensation, an amendment to the Employee Stock Purchase Plan, and ratification of the independent auditor. The Board recommends voting FOR all director nominees and FOR Proposals 2, 3 and 4.

The company highlights a strong fiscal 2025, with record results from continuing operations. Sales reached $1,095 million, up 19% year over year, net earnings were $116.3 million, and diluted EPS was $4.49, a 13% increase. Entered orders were $1,565 million and net cash from operating activities was $200 million, both rising sharply, while ending backlog grew 71%. ESCO completed the acquisition of Signature Management & Power (now ESCO Maritime Solutions) and divested VACCO Industries, sharpening its focus on defense and industrial markets.

The proxy details governance practices, committee structures and director independence, and explains a pay‑for‑performance executive compensation program that ties most CEO and senior officer pay to financial metrics such as Adjusted EPS, Adjusted Cash Flow from Operating Activities, EBITDA growth and return on invested capital.

	Dear Fellow Shareholders,
	I am pleased to invite you to attend our 2026 Annual Meeting of Shareholders of ESCO Technologies Inc., to be held on Friday, January 30, 2026 at our corporate headquarters in St. Louis, Missouri.
	The accompanying Notice of Annual Meeting and Proxy Statement describe the items of business that will be discussed and voted on at the Meeting. We value your input and encourage you to review this material as well as our Annual Report for fiscal 2025 and to vote your shares of common stock. You have a choice of voting online, by telephone, by returning the enclosed proxy card by mail, or at the Meeting.
	Backed by broad engineering expertise and a highly skilled workforce, ESCO is dedicated to the design and production of advanced solutions that enhance performance, reliability, and safety across the industries we serve. With a long-standing commitment to our customers, we focus on developing the next generation of technologies to address today’s most complex challenges.
	In 2025, ESCO reached a pivotal milestone in its strategic evolution through two significant portfolio actions. We completed the acquisition of Signature Management & Power (SM&P) - now operating as ESCO Maritime Solutions (Maritime) - and the divestiture of VACCO Industries. These moves strengthen our presence in the Navy sector and narrow our focus in serving markets that offer resilient, long-term growth opportunities.
	Overall, 2025 was a remarkable year for ESCO, as we again delivered record revenue, earnings, orders, and ending backlog. On a continuing operations basis, revenue increased 19 percent, GAAP EPS increased 13 percent, and ending backlog increased 71 percent over the prior year as we continued to see strong demand across our core defense and industrial markets.
	On behalf of the Board of Directors and all of us at ESCO, thank you for your ongoing support.
	Sincerely,
	Bryan Sayler
	Chief Executive Officer and President

2 ESCO Technologies Inc. Proxy Statement

COMPANY OVERVIEW AND BUSINESS HIGHLIGHTS

We conduct our business through a number of wholly-owned direct and indirect subsidiaries and are:

● A key supplier of highly engineered hydraulic filtration systems, fluid control valves, machined components, and metal finishing for the aerospace industry, as well as complex shock and vibration dampening tiles and signature and power management solutions that enhance the stealth capabilities of submarines and surface ships;

● An industry leader in radio frequency shielding and electromagnetic compatibility test products; and

● A leading provider of diagnostic instruments, software, and services for the benefit of industrial power users and the electric utility and renewable energy industries.

In 2025, strong end-market demand and the acquisition of ESCO Maritime Solutions drove record orders, sales, and backlog. We leveraged that growth to deliver improved profit margins and a 13 percent increase in diluted EPS. With a solid balance sheet and substantial liquidity, we are well positioned to fund both internal investments to support organic growth and acquisitions to further expand our technology-driven portfolio of products and services.

The following are selected measures of Company performance on a Continuing Operations basis. For complete financial information, please see the audited financial statements included in our 2025 Annual Report to Shareholders.

2025 Sales		Net Earnings		Diluted Earnings Per Share
$1,095M		$116.3M		$4.49
RECORD SALES/ +19% OVER PRIOR YEAR		+13% OVER PRIOR YEAR		+13% OVER PRIOR YEAR
Entered Orders		Net Cash Provided by Operating Activities		Leverage Ratio
$1,565M		$200M		0.56x
RECORD ORDERS & ENDING BACKLOG ORDERS +57% / BACKLOG +71% OVER PRIOR YEAR		+65% OVER PRIOR YEAR

Proxy Statement ESCO Technologies Inc. 3

GOVERNANCE HIGHLIGHTS

● All directors other than the CEO are independent

● All committee chairs are independent

● Each director attended at least 75% of Board and committee meetings

● Independent directors hold executive sessions during each Board meeting

● Board conducts self-assessments annually

● The full Board exercises oversight responsibility for material risks, and delegates oversight of other risks to the appropriate committees

● Four of our eight directors are diverse in gender and/or ethnicity

● Robust clawback policy for executive compensation plans

● Competitive share ownership guidelines for directors and executive officers

● Executive compensation driven by pay for performance

● Annual shareholder vote on executive compensation

● Executive officers and directors may not hedge or pledge company shares

● Independent directors review CEO performance annually

● Average tenure of independent directors is 6 years

● Median age of independent directors is 65 years

EXECUTIVE COMPENSATION HIGHLIGHTS

Our compensation objective is to develop and maintain an industry-competitive compensation program that attracts, retains, motivates and rewards our executive officers and other senior officers and key executives. The compensation program is designed to emphasize performance-based compensation in alignment with our business strategy.

Our compensation programs are designed to maximize shareholder value by allocating a significant portion of executive compensation to performance-based pay that is dependent on the achievement of our performance goals. Our annual cash incentive program and equity-based Performance Share Unit awards (PSUs) utilize a variety of key strategic and financial performance metrics and are designed to reward positive financial performance and limit unnecessary risk taking. Stock ownership guidelines align the interests of executives and shareholders by ensuring that executives bear the economic risk of share ownership.

For 2025, our Human Resources and Compensation Committee used the performance metrics “Adjusted EPS” and “Adjusted Cash Flow from Operating Activities,” to determine cash incentive plan compensation earned during fiscal 2025 and thereby incent the participants and align cash incentive compensation with business objectives. The metrics used in the calculation of the 2025 adjustment differed somewhat from those used to calculate the 2024 adjustment; for a detailed description, see 2025 Cash Incentive Metrics in the Compensation Discussion and Analysis section.

Our long-term equity incentive (LTI) program includes Restricted Share Units (RSUs) which fully vest over a period of 3 to 3¹/₂ years and, since fiscal 2022, PSUs with a 3-year performance period, as described in the Compensation Discussion and Analysis section below.

4 ESCO Technologies Inc. Proxy Statement

The following charts summarize the 2025 pay mix for the CEO and the other named executive officers, with 81% of the CEO’s target direct compensation at risk and 63% of the average of the other named executive officers’ target direct compensation at risk. Target direct compensation is defined as the sum of the executive officer’s base salary, annual cash incentive award, and annual long term incentive awards, in each case calculated at the target level approved by the Committee.

VOTING

Whether or not you expect to be present in person at the Meeting, please vote in advance using one of the voting methods described in the Important Notice Regarding the Availability of Proxy Materials sent to the shareholders on or about December 10, 2025, which contained instructions on how to access the proxy materials and vote electronically via the Internet, by telephone, by mail, or in person. That Notice also contained instructions on how to request a paper or e-mail copy of the proxy materials, including the Company’s 2025 Annual Report to Shareholders, this Proxy Statement, and a proxy card. The 2025 Annual Report to Shareholders and this Proxy Statement are also available for review on the Company’s website, www.escotechnologies.com.

● You may vote on each proposal, by proxy or by voting in person or via the Internet or by telephone, in which case your shares will be voted in accordance with your choices.

● You may abstain from voting on any one or more proposals, or withhold authority to vote for any one or more directors, which will have the effect described under Required Vote below.

● You may return a properly executed proxy form without indicating your preferences, in which case the proxies will vote the shares according to the Board’s recommendations.

You will have the right to revoke your proxy at any time before it is voted by giving written notice of revocation to the Secretary of the Company, or by duly executing and delivering a proxy bearing a later date, or by attending the Meeting and casting a contrary vote in person.

HOW TO VOTE

Via the Internet	By Telephone	By Mail	At the Meeting
Go to www.investorvote.com/ESE	1-800-652-VOTE (8568) in the U.S. or Canada	Follow the instructions on your proxy card	Attend in person and vote by ballot

REQUIRED VOTE

At the Meeting, shareholders will be entitled to cast one vote for each share held by them of record on the record date. There is no cumulative voting with respect to the election of directors. The Company has no non-voting shares.

The affirmative vote of the holders of a majority of the shares represented in person or by proxy at the Meeting and entitled to vote on the matter in question will be required to elect directors, to approve each of the individual proposals described in this Proxy Statement, and to approve any other matters properly brought before the Meeting.

The Company’s Corporate Governance Guidelines provide that an incumbent director who fails to obtain a majority vote must promptly offer his or her resignation to the Chair, and the remaining directors shall meet to consider whether it is in the best interests of the Company to accept the resignation or to permit the incumbent to remain on the Board for such period of time as the Board may determine or until a successor is elected and qualified.

6 ESCO Technologies Inc. Proxy Statement

Shares represented by proxies which are marked “Withhold” authority to vote for the election of one or more of the nominees for election as directors or marked “Abstain” on any one or more of the other individual proposals described in this Proxy Statement will be counted for the purpose of determining the number of shares represented by proxy at the Meeting, but proxies so marked will have the same effect as if the shares were voted against such nominee or nominees or such proposals.

Under the Rules of the NYSE, the proposal to approve the appointment of independent registered public accountants is considered a “discretionary” item, which means that brokerage firms may vote in their discretion on this matter on behalf of clients who have not furnished voting instructions at least 10 days before the date of the Meeting. In contrast, the election of directors and the other items on the Meeting agenda are “non-discretionary” items, which means that brokerage firms that have not received voting instructions from their clients on these proposals may not vote on them. These so-called “broker non-votes” will, if the underlying shares are otherwise represented at the Meeting, be considered to be present for purposes of determining a quorum, but will be treated as not entitled to vote on such non-discretionary or matters; they will therefore not be considered in determining the number of votes necessary for approval and will have no effect on the outcome of the votes for directors or the other matters to be considered at the Meeting. If your shares are held by a broker, it is important that you provide voting instructions to your broker so that your votes will be counted.

Mr. Sayler is the only Board member who is a member of the Company’s management. The Board of Directors has affirmatively determined that none of the non-management directors has any material relationship with the Company other than in his or her capacity as a director and shareholder, and that therefore all of those directors are, and at all times during their service in fiscal 2025 were, independent as defined under the Company’s Corporate Governance Guidelines and the listing standards of the NYSE.

Meetings

The Board of Directors held five meetings during fiscal 2025. All of the directors attended, either in person or by video conference call, at least 75% of the meetings of the Board and of each of the committees on which they served which were held during their periods of service. The Company’s policy requires that all directors attend the Annual Meeting, except for absences due to causes beyond the reasonable control of the director. All of the directors serving at the time of the 2025 Annual Meeting attended the meeting.

DIVERSITY AND TENURE

Diversity is one of the factors that our Governance Committee considers in identifying the pool of director search candidates. The Board appreciates the benefits diversity brings and strives to assemble a Board with not only a variety of business and professional backgrounds, but also diversity in areas such as race, ethnicity and gender.

COMMITTEES

The members of the Board of Directors are appointed to various committees. The standing committees of the Board are the Executive Committee, the Audit and Finance Committee (Audit Committee), the Nominating and Corporate Governance Committee (Governance Committee), and the Human Resources and Compensation Committee (Compensation Committee).

Each Committee operates under a written charter adopted by the Board of Directors. The charters are posted on the Company’s website, www.escotechnologies.com, under the Investor Center/Committees & Charters tab, and a copy of each Committee’s charter is available in print to any shareholder who requests it.

Director Candidates and Nominations

To be considered for nomination to the Board, candidates must be persons of the highest integrity, have extensive and varied business experience and have demonstrated their ability to interact effectively with associates and peers. They preferably will also have experience and expertise in business areas related to the Company and its technologies, industries and customers. In addition, the Committee will seek out candidates with the ability to interact constructively with the existing Board membership, in order to enable the Board to act in the long-term interests of the Company’s shareholders. While the Committee has not established specific minimum qualifications for candidates, it may establish specific membership criteria as appropriate from time to time if the Board determines there is a need for specific skills and industry experience.

The Committee does not have a formal policy on diversity and it seeks the most qualified candidates without regard to race, color, national origin, gender, religion, disability or sexual orientation. The Committee appreciates the benefits that diversity, including gender diversity, brings to a board of directors, and both the Committee and the full Board are committed to requiring the inclusion of women and underrepresented minorities in the initial pool of director search candidates.

The Committee may identify new candidates for nomination based on recommendations from Company management, employees, non-management directors, shareholders and other third parties. It also has the authority to engage third party search firms to identify candidates, and it has done so from time to time. Consideration of a new candidate typically involves the Committee’s review of information pertaining to such candidate and a series of internal discussions, and may proceed to interviews with the candidate. New candidates are evaluated based on the above-described criteria in light of the specific needs of the Board and the Company at the time. Incumbent directors whose terms are set to expire are evaluated based on the above-described criteria, as well as a review of their overall past performance on the Board of Directors.

CORPORATE GOVERNANCE INFORMATION

The Board’s Role in Risk Oversight

The Company’s management is responsible for managing the Company’s risks on a day-to-day basis, and has adopted an ongoing enterprise risk management process that it uses to identify and assess Company risks. Management has identified risks in four general areas: Financial and Reporting; Legal and Compliance; Operational; and Strategic. Periodically, management advises the Board and the appropriate Board committee of the risks identified; management’s assessment of those risks at the business unit and corporate levels; its plans for the management of these identified risks or the mitigation of their effects; and the results of the implementation of those plans.

While the Board as a whole has responsibility for and is involved in the oversight of management’s risk management processes, plans and controls, some of the identified risks are given further review by the Board committee most closely associated with the identified risks. For example, the Audit Committee provides additional review of the risks in the areas of accounting and auditing, liquidity, credit, tax, information security and cybersecurity. Similarly, the Compensation Committee provides additional review of risks in the area of compensation and benefits and human resource planning. The Governance Committee devotes additional time to the review of risks associated with corporate governance, ethics, legal and sustainability issues.

Governance Policies and Management Oversight

The Board of Directors has adopted Corporate Governance Guidelines to guide its actions, as well as a Code of Conduct applicable to all of the Company’s directors, officers and employees. Additionally, the Board has adopted a Code of Ethics for Senior Financial Officers applicable to the Company’s Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer, Controller and persons performing similar duties. These documents are posted on the Company’s web site, www.escotechnologies.com, under the Investor Center/Governance Documents tab, and a copy of any of these documents is also available in print to any shareholder who requests it.

Insider Trading and Clawback Policies

In furtherance of the Corporate Governance Guidelines and the Code of Conduct, and in coordination with applicable securities-related laws and regulations, the Board of Directors has adopted robust policies regarding Insider Trading, including prohibitions against hedging and (for certain senior Company officials) pledging transactions involving Company stock, and policies permitting the Company to “claw back” all or part of the values of certain Company equity awards to executives or senior personnel in certain cases. Further information about these policies is set forth under Insider Trading Policy; Anti-Hedging and Anti-Pledging Policies and Clawback Policy beginning on page 40.

Cybersecurity

Global information technology security threats and targeted computer crime are increasing in frequency and sophistication. As these risks increase, the Company has enhanced its use of technologies and internal controls to protect our systems, networks and data. The Company’s cybersecurity program includes employee training and testing, information security policies and procedures, third-party monitoring of our networks and systems, and maintenance of backup and other protective systems. Governmental authorities, including the United States government, have increasingly focused on cybersecurity requirements for government contractors. The Company’s subsidiaries that serve in these capacities are increasingly focused on cybersecurity as they seek to comply with the US Department of Defense Cybersecurity Maturity Model Certification (CMMC) program and related governmental mandates.

The Audit Committee annually reviews the major financial risk exposures including cyber security and policies or controls management has implemented to manage and mitigate risks, and quarterly reviews management’s assessment and oversight of cybersecurity and information technologies risks and any required remediation actions. The full Board annually reviews the Company’s cybersecurity initiatives.

Proxy Statement ESCO Technologies Inc. 19

Succession Planning

The Compensation Committee of the Board conducts an annual review of the Company’s long-term succession plan for the CEO. Additionally, the Board has in place an emergency succession plan for the CEO in order to minimize the uncertainty associated with an emergency succession event.

Independence and Related Person Determinations

All of the Company’s directors except Mr. Sayler are and will be independent of Company management. Additionally, all of the members of the Audit Committee, the Compensation Committee and the Governance Committee are independent as defined by the New York Stock Exchange and set forth in the Company’s Corporate Governance Guidelines.

The Company has implemented a written policy not only to ensure that all non-management directors meet the independence standards defined under the Company’s Corporate Governance Guidelines and the listing standards of the NYSE but to ensure that all Company transactions in which a “Related Person” has or will have a direct or indirect interest will be at arm’s length and on terms generally available to an unaffiliated third-party under the same or similar circumstances. “Related Persons” include the Company’s directors, director nominees and executive officers, holders of 5% or more of the Company’s stock, and the immediate family members of each. The policy contains procedures requiring Related Persons to notify the Company of any such transaction and for the Governance Committee to review the material facts of the proposed transaction and determine whether to approve or disapprove the transaction. The Committee will consider whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third-party under the same or similar circumstances. If advance Committee approval is not feasible or is not obtained, the policy requires submission of the transaction to the Committee after the fact, and the Committee is empowered to approve, ratify, amend, rescind or terminate the transaction. In such event, the Committee will also request the General Counsel to evaluate the Company’s controls and procedures to ascertain whether any changes to the policy are recommended.

The Company has developed and implemented processes and controls to obtain information about Related Person transactions for the purpose of determining, based on the facts and circumstances, whether a Related Person has a direct or indirect material interest in the transaction. Pursuant to these processes and controls, all directors and executive officers must annually complete, sign and submit a Directors’ and Officers’ Questionnaire and a Conflict of Interest Questionnaire that are designed to identify Related Person transactions and both actual and potential conflicts of interest, and are required to update their responses in the event of any changes. Additionally, the holders of 5% or more of the Company’s shares (all of whom are institutional investors), are annually requested to respond to certain questions designed to identify direct or indirect material interests by such 5% or more shareholder in any transactions with the Company.

Based on its review and processes, the Company has determined that except for the matters described in the following paragraphs there has been no transaction since the beginning of the Company’s 2025 fiscal year, and there is no transaction currently proposed, in which the Company was or is to be a participant and in which any Related Person had or will have a direct or indirect material interest.

One of the Company’s directors, David A. Campbell, is the President, Chief Executive Officer and Chairman of the Board of Evergy, Inc. (Evergy), which through its operating subsidiaries is a customer of the Company’s subsidiary Doble Engineering Company and its subsidiaries and affiliates (together, Doble). Accordingly, the Board has affirmatively considered whether this relationship might affect Mr. Campbell’s independence as a director of the Company. The Board determined that Doble, among other things, sells and leases equipment and software to Evergy, repairs and calibrates the equipment and maintains the software, and provides testing, training and consulting services to Evergy, all in the ordinary course of their respective businesses; that the total amount of these transactions was less than $800,000 in each of 2024 and 2025, which was approximately 0.03% of Evergy’s spend for calendar 2024 (the last year for which information was available for Evergy), and approximately 0.08% and 0.07% of the Company’s 2024 and 2025 revenues, respectively; that Mr. Campbell was not personally involved in these transactions; and that all transactions between Doble and Evergy are intended to be and have been consistent with Doble’s normal commercial terms offered to its customers.

20 ESCO Technologies Inc. Proxy Statement

In addition, another of the Company’s directors, Penelope M. Conner, is the Executive Vice President of Customer Experience and Energy Strategy of Eversource Energy (Eversource), which through its operating subsidiaries is a customer of Doble. Accordingly, the Board has affirmatively considered whether this relationship might affect Ms. Conner’s independence as a director of the Company. The Board determined that Doble, among other things, sells and leases equipment and software to Eversource, repairs and calibrates the equipment and maintains the software, and provides testing, training and consulting services to Eversource, all in the ordinary course of their respective businesses; that the total amount of these transactions was approximately $3.7 million in 2024 and approximately $3.9 million in 2025, which was approximately 0.06% of Eversource’s spend for calendar 2024 (the last year for which information was available for Eversource), and less than 0.4% of the Company’s revenues for each of 2024 and 2025; that Ms. Conner was not personally involved in these transactions; and that all transactions between Doble and Eversource are intended to be and have been consistent with Doble’s normal commercial terms offered to its customers.

Based on its review and consideration of these facts, and Mr. Campbell’s and Ms. Conner’s oral and written representations, the Board determined that the relationships between the Company and Evergy and between the Company and Eversource are not material, that the relationships will not affect Mr. Campbell’s or Ms. Conner’s independent judgment on matters affecting the Company, and that Mr. Campbell and Ms. Conner are each independent under the standards of both the New York Stock Exchange and the Company’s Corporate Governance Guidelines.

Communications with Directors

Interested parties desiring to communicate concerns regarding the Company to the Chair of the Board or to the non management Directors as a group may direct correspondence to: Mr. Robert J. Phillippy, Chair, ESCO Technologies Board of Directors, ESCO Technologies Inc., 645 Maryville Centre Drive, Suite 300, St. Louis, MO 63141-5855. Alternatively, interested parties who wish to communicate with an individual director or any group of directors may write to such director(s) at ESCO Technologies Inc., 645 Maryville Centre Drive, Suite 300, St. Louis, MO 63141-5855, Attn: Secretary. All such letters will be forwarded promptly to the relevant director(s).

DIRECTOR COMPENSATION

The responsibilities and the substantial time commitment of a director at a public company require that the Company provide reasonable compensation to incentivize the directors’ performance and ensure their willingness to continue to serve. The Company strives to engage and retain well-qualified directors with significant experience at companies of similar size and complexity. To ensure this is achieved, the Company regularly reviews the compensation provided to its directors. The Company’s non-employee directors are compensated pursuant to the Sub-Plan for Compensation of Non-Employee Directors under the 2018 Omnibus Incentive Plan (the Director Compensation Plan) based upon their respective levels of Board participation and responsibilities. The Compensation Committee obtains competitive market and peer data and periodically retains a compensation consultant to evaluate the competitiveness of its director compensation. The Committee approves the directors’ compensation, but any changes are ratified by the full Board. As an employee of the Company, Mr. Sayler does not receive compensation for his service as a director.

The annual compensation for non-employee directors is based on a calendar year and is paid or awarded, as the case may be, on and as of the first NYSE trading day after each Annual Meeting of Shareholders.

Components of Calendar 2025 and 2026 Director Compensation

Cash Compensation	2025	2026
Annual Retainer (all non-management directors)	$50,000	$50,000
Chair of the Board	$85,000	$100,000
Committee Chairs:
Audit	$17,500	$17,500
Compensation	$15,000	$15,000
Governance	$12,000	$12,000

Equity Compensation	2025	2026
Restricted Share Award (all non-management directors)(1)	$180,000	$180,000

(1) The annual equity award consists of a number of restricted share units (RSUs) equal to $180,000 divided by the NYSE closing price of the common stock on the award date, rounded to the nearest whole share and vesting one year after the award date. The equity award for calendar 2025 was made on February 5, 2025 and will vest on February 5, 2026. Based on the NYSE closing stock price of $133.61 on the award date it amounted to 1,347 RSUs per director, with a grant date value of $179,973.

For their service as directors during the latter part of calendar 2024, Mr. Campbell and Ms. Conner each received a prorated initial cash retainer of $25,000 and a prorated initial equity award of RSUs valued at approximately $90,000. The partial-year calendar 2024 equity award to Mr. Campbell was made on October 16, 2024, based on the NYSE closing stock price of $124.57 on September 25, 2024, the effective date of his election; rounded to the nearest whole share it amounted to 722 RSUs, with a grant date value of $89,940. The partial-year 2024 equity award to Ms. Conner was made on November 6, 2024, based on the NYSE closing stock price of $127.89 on October 25, 2024, the effective date of her election; rounded to the nearest whole share it amounted to 704 RSUs, with a grant date value of $90,035. Like the full-year annual awards, each award vested one year after the award date.

During the vesting period, each director’s RSU account accrues an additional number of unvested RSUs equivalent to the quarterly dividends that would have been paid on a like number of shares of common stock, divided by the NYSE closing price on the dividend date; and on the vesting date the director’s accrued and vested RSUs are converted into whole shares of common stock, plus cash equal to the value of any fractional shares based on the NYSE closing price on the vesting date, and are distributed and paid to the director, or if the director has elected to defer their compensation as described below, the RSUs are retained in the director’s deferred compensation account as vested common stock equivalents until the elected distribution date.

2026 Compensation Change

The Compensation Committee reviewed the non-management directors’ annual compensation program in August 2025, and based on its recommendations the Board determined to increase the annual compensation of the Board Chair for calendar 2026 as stated in the table above.

Election to Defer Compensation

Directors may elect in advance to defer receipt of all of their cash compensation and/or all of their stock compensation. If deferral is elected, the deferred amounts are credited to the director’s deferred compensation account in common stock equivalents. If cash compensation is deferred, the number of common stock equivalents credited is equal to the amount deferred divided by the NYSE closing price of the common stock as of the date on which the deferral occurs (or if that is not a trading day, then the last preceding trading day). If stock compensation is deferred, the number of common stock equivalents credited is equal to the number of shares whose receipt is deferred. Common stock equivalents in the director’s deferred compensation account have no voting rights, but earn dividend equivalents on each dividend payment date equal to the dividends payable on a like number of shares of common stock; and the dividend equivalents earned are credited to the director’s deferred compensation account as additional common stock

22 ESCO Technologies Inc. Proxy Statement

equivalents valued at the NYSE closing price on the dividend date. A director’s deferred compensation account becomes distributable when the director leaves the Board, or at such other date as may be specified by the director consistent with the terms of the Director Compensation Plan; distribution will be accelerated in certain circumstances, including a change in control of the Company. The account is distributable at the election of the director either in cash or in shares; however, any stock portion which has been deferred may only be distributed in shares. For fiscal 2025, Mr. Campbell, Mr. Dewar, Ms. Hess and Mr. Olivier elected to defer receipt of their cash compensation and stock compensation. In addition, Mr. Phillippy’s and Ms. Valdez’s cash and stock compensation from certain prior years continued to be deferred pursuant to prior deferral elections which they had terminated as to future compensation.

Director Stock Ownership Guidelines

Directors are subject to stock ownership guidelines. Under these guidelines, within five years after their appointment to the Board each non-management director is expected to acquire and hold shares or common stock equivalents having a total cash value equal to at least five times the annual cash retainer. All directors currently exceed the ownership guidelines.

Proposal 2:

ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION

The Board of Directors recommends a vote FOR this Proposal.

Pursuant to Section 14(a) of the Securities Exchange Act of 1934, the Board of Directors is again soliciting an advisory (non-binding) shareholder vote, commonly referred to as “Say-on-Pay”, to approve the compensation of the executive officers whose compensation is disclosed in this Proxy Statement (the named executive officers or NEOs). At our 2025 Annual Meeting, over 98% of the shares represented and entitled to vote on the Say on Pay proposal, and over 91% of all outstanding shares, were voted in support of the Say-on-Pay proposal. Based on the preference of over 93% of the votes cast on the frequency of the Say-on-Pay proposals in 2023, we plan to continue to hold a Say-on-Pay vote every year.

The Board of Directors strongly endorses our executive compensation program and recommends that the shareholders vote in favor of the following Resolution:

“RESOLVED, that the Company’s shareholders approve, on an advisory basis, the compensation of the named executive officers as disclosed in the Company’s Proxy Statement for the 2026 Annual Meeting of Shareholders pursuant to the executive compensation disclosure rules of the Securities and Exchange Commission, including the Compensation Discussion and Analysis, the Summary Compensation Table, and the other related tables and narrative disclosure.”

Shareholders are encouraged to review the Compensation Discussion and Analysis section below as well as the Summary Compensation Table and the other related tables and narrative disclosure referred to in the proposed Resolution, which provide details about our executive compensation program as well as specific information about 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 the named executive officers as described in this Proxy Statement. Although the vote is non-binding, the Board of Directors and the Compensation Committee value the opinions of the shareholders, and to the extent there is a significant vote against the above resolution the Company will consider the shareholders’ concerns and the Committee will evaluate what actions (if any) may be necessary to address those concerns.

SUMMARY OF EXECUTIVE COMPENSATION PROGRAM

Our executive compensation program is designed to attract, motivate, and retain executive officers who are critical to our success. The Committee believes that the program constitutes a balanced, competitive approach to compensation that supports our compensation objectives through performance-based compensation that aligns the interests of executives with those of our shareholders.

The Compensation Committee reviews our compensation program at least annually to ensure that it achieves the desired goals of aligning our executive compensation structure with shareholders’ interests and current market practices.

2025 Performance Related to Executive Compensation

The Compensation Committee established two performance metrics, “Adjusted EPS” and “Adjusted Cash Flow from Operating Activities,” to determine incentive plan compensation earned during fiscal 2025 and thereby incent the participants and align cash incentive compensation with business objectives. Adjusted EPS and Adjusted Cash Flow from Operating Activities are non-GAAP measures; for a detailed description and a reconciliation to the nearest GAAP measure, see 2025 Cash Incentive Metrics, below.

Pay for Performance

Our compensation programs are designed to maximize shareholder value by allocating a significant portion of executive compensation to at-risk pay. Our annual cash incentive program and equity-based PSUs utilize a variety of key strategic and financial performance metrics and are designed to reward positive financial performance and limit unnecessary risk taking. Stock ownership guidelines align the interests of executives and shareholders by ensuring that executives bear the economic risk of share ownership.

Compensation Objective

The Compensation Committee’s objective is to develop and maintain industry-competitive compensation packages to attract, retain, motivate and reward our executive officers and other senior officers and key executives. Compensation programs are designed to be consistent with those of other companies engaged in similar industries and/or of similar size with which we are likely to compete for talent to enable us to employ and retain a high-quality management team. The Committee seeks to use performance-based compensation to maximize the alignment of executive compensation with the long-term interests of our shareholders.

The Committee sets compensation levels based on the skills, experience and performance of each executive officer, taking into account the benchmarking described below and compensation recommendations made by the CEO (except with respect to his own position). The Committee’s pay for performance philosophy is reflected in the annual compensation review. The Committee also considers tally sheets which provide, for each executive officer, a recap of each principal element of compensation as well as benefits, perquisites, equity awards, and stock ownership and potential ownership. The tally sheets also reflect the incremental compensation which would be payable as a result of various termination scenarios and each element of pay or benefits impacted. The Committee retains the discretion to adjust all elements of compensation as it deems appropriate, subject to the requirements of shareholder-approved plans.

Compensation Consultant and Benchmarking

The Compensation Committee is authorized by its charter to employ independent compensation and other consultants. The Committee annually engages with a nationally recognized compensation consulting firm (Compensation Consultant) to assist the Committee in evaluating executive compensation. The Compensation Consultant provides information, research and analysis pertaining to executive compensation as requested by the Committee, including updates on the peer group, market trends, survey data and analysis for market review. The Committee also from time to time engages our primary outside counsel, Bryan Cave Leighton Paisner LLP (BCLP) to advise it on selected executive compensation issues.

2024 Compensation Report (Fiscal 2025 Compensation Review)

In the summer of 2024, the Committee engaged Pay Governance LLC as the Compensation Consultant to provide a compensation report (the 2024 Compensation Report) for the Committee’s fiscal 2025 compensation review. One of the elements of the 2024 Compensation Report was the 2024 Mercer Benchmark Database/Total Remuneration Survey – Executive (the Mercer Survey), a broad-based survey of management compensation, as the primary source for benchmarking its executive compensation levels. A broad market survey provides decision-quality data that is generally reliable and consistent year-over-year. The Company was a participant in the Mercer Survey. A list of all of the participating companies included in the Mercer Survey is attached as Appendix B to this Proxy Statement.

For its 2024 Compensation Report, the Compensation Consultant also provided proxy data from the peer group described below (2024 Peer Group) to be used in conjunction with the Mercer Survey in order to add context to the decision-making process and provide a supplemental perspective on the market. Peer group proxy data provides transparent line-by-line information for each company in the peer group, and provides the ability to review industry trends and compensation design practices as well as pay-for-performance alignment. The 2024 Peer Group was based on the GICS codes assigned to the Company’s subsidiaries and represented companies in the following industries in which the Company participates:

	●	Industrial valves	●	Printed circuit boards
	●	General industrial machinery	●	Instruments to measure electricity
	●	Radio and television	●	Services not elsewhere classified
	●	Communications equipment

Companies in the above industries were then filtered for revenue size in order to determine the 2024 Peer Group. The following is a list of the companies in the 2024 Peer Group, with their ticker symbols:

Albany International Corp. (AIN)	Kadant Inc. (KAI)
Ameresco, Inc. (AMRC) *	MACOM Technology Solutions Holdings Inc. (MTSI)
Badger Meter, Inc. (BMI) *	Mueller Water Products, Inc. (MWA) *

Fiscal 2025 Benchmarking

For its compensation review for fiscal 2025, the Committee reviewed each principal element of compensation (base salary, cash incentive and LTI), as well as total cash compensation (base salary and cash incentive), and total direct compensation (target cash compensation and LTI) for each of the Company’s executive officer positions, and compared them against the benchmark range from the Compensation Report. For all three of the NEOs, the benchmark range for each element of compensation in the Compensation Report is the median plus or minus 15%. For fiscal 2025, the Committee utilized the benchmark ranges from the Compensation Report in determining the competitiveness of the executives’ compensation. The Committee also compared relative Company performance against the performance of the companies in the 2024 Peer Group to test the overall reasonableness of pay for performance.

The Committee used the Compensation Report described above as a guideline and frame of reference in determining appropriate compensation levels and incentives for the executive officers; however, the Committee does not make its decisions according to a formula, and the Committee exercises considerable judgment and discretion in making them. The complexity and composition of the Company does not lend itself to comparisons with a readily ascertainable peer group, and while matching by SIC codes can provide some measure of comparability, there are wide variations in the type and complexity of these companies. The Committee therefore considers the benchmark ranges to be only a guide, and makes individual determinations of compensation for each of the executive officers based on numerous factors including the comparative responsibilities of the executive officers and the Committee’s assessments of individual and Company performance.

Change in Compensation Consultant for Fiscal 2026

In May 2025, the Committee engaged Meridian Compensation Partners (Meridian) as the Compensation Consultant for fiscal 2026.

Compensation Consultant Independence

In August 2024 and August 2025, the Committee assessed the independence of the Compensation Consultant and BCLP in line with the SEC’s compensation consultant independence factors, and determined there were no conflicts of interest. The Committee will continue to review their independence status annually and will keep the compliance letters on file.

Principal Elements of Compensation Program

The principal elements of the 2025 compensation program for executive officers (base salary, annual cash incentive and long-term equity incentive) are reflected in the Summary Compensation Table on page 41. Each of these elements is described in detail in the corresponding sections below.

Pay Element	Form	2025 Metrics	Objectives
Base Salary	Cash	Benchmarked to market median, subject to adjustment for individual factors such as experience and performance	Attract and retain qualified executives
Annual Incentive Plan (PCP)	Cash	100% based on financial results: ●       70% based on Adjusted EPS ●       30% based on Adjusted Cash Flow from Operating           Activities	Drive profitability, growth and progress against strategy

30 ESCO Technologies Inc. Proxy Statement

We do not believe that any risks arising from our compensation policies and practices are reasonably likely to have a material adverse effect on the Company. Any such risk is mitigated by the multiple elements of the compensation programs, including base salary, annual cash incentive programs, and LTI awards which are earned over multiple years. This structure encourages decision-making that is in the best long-term interests of the Company and our shareholders.

Total Direct Compensation

The executive officers receive total direct compensation consisting of cash compensation (base salary plus annual cash incentive compensation) and long-term equity incentive compensation. Each of these elements is described in detail in the corresponding sections below.

The Committee sets target levels for total direct compensation based on the skills, experience, breadth of their role, and performance of each executive officer, taking into account the benchmarking described above and compensation recommendations made by the CEO (except with respect to his own position). The Committee also considers the Company’s performance. For fiscal 2025, the Committee increased the executive officers’ total direct compensation as described in detail below. Total direct compensation for fiscal 2025 was within the benchmark range for Mr. Sayler, slightly above the benchmark range for Mr. Tucker, and within the benchmark range for Mr. Schatz.

Base Salaries

Base salaries are designed to attract, retain, motivate and reward competent, qualified, experienced executives, although we emphasize performance-based compensation for the executive officers.

Fiscal 2025 base salaries for the executive officers were set by the Committee in the first quarter of fiscal 2025. Annual base salaries for the executive officers for fiscal 2025 and fiscal 2024 were as follows:

Base Salaries⁽¹⁾

Officer	FY 2025 Base Salary	FY 2024 Base Salary	Percent Increase from FY 2024
Bryan H. Sayler	$830,500	$755,000	10%
Christopher L. Tucker	$616,500	$598,500	3%
David M. Schatz	$426,100	$405,800	5%

(1) Amounts shown are annual rates for fiscal 2025; the actual amounts paid are set forth in the Summary Compensation Table.

Changes to Base Salaries for Fiscal 2026

For fiscal 2026 the Committee determined that increases in base salary of 8.4%, 3.9% and 4.5% were warranted for Mr. Sayler, Mr. Tucker and Mr. Schatz, resulting in base salaries of $900,000, $640,500 and $445,300 respectively. To assist in evaluating 2026 executive compensation, the Committee engaged Meridian to conduct a comprehensive 2025 market assessment.

Proxy Statement ESCO Technologies Inc. 31

Annual Cash Incentive

The Committee uses annual performance-based cash incentives to compensate the executive officers. The Committee establishes at-risk performance targets for the executive officers using financial and operational goals linking compensation to overall Company performance. The annual cash incentive targets for fiscal 2025 and fiscal 2024 were as follows:

Target Cash Incentive Compensation⁽¹⁾ 

Officer	FY 2025 Target Cash Incentive	FY 2024 Target Cash Incentive	Percent Increase from FY 2024
Bryan H. Sayler	$830,500	$755,000	10%
Christopher L. Tucker	$400,700	$389,000	3%
David M. Schatz	$213,100	$202,900	5%

(1) Amounts shown are annual targets for fiscal 2025; the actual amounts paid are set forth in the Summary Compensation Table.

The fiscal 2025 cash incentive targets for the executive officers were established pursuant to our Performance Compensation Plan (PCP) authorized under the 2018 Omnibus Incentive Plan. This at risk plan closely links the executive officers’ pay to our financial results and provides compensation variability in the form of reduced payments when performance is below targets and higher compensation when performance exceeds targets. The PCP has a fixed target with a payout range based on performance. The Committee has discretion to either increase or decrease the actual cash incentive payouts. For fiscal 2025, the Committee determined to set the cash incentive targets as a percent of base salary in line with market practices. The 2025 cash incentive targets for Mr. Sayler, Mr. Tucker and Mr. Schatz were 100% of 2025 base salary, 65% of 2025 base salary, and 50% of 2025 base salary, respectively.

Changes to Annual Cash Incentive for Fiscal 2026

Consistent with fiscal 2025, the Committee determined that the cash incentive targets for fiscal 2026 would be set as a percent of base salary in line with market practices. The fiscal 2026 cash incentive targets for Mr. Sayler, Mr. Tucker and Mr. Schatz are $900,000 (100% of 2026 base salary), $448,400 (70% of 2026 base salary), and $267,200 (60% of 2026 base salary), respectively.

Total Target Cash Compensation

The target percentages of total cash compensation represented by base salary and by the PCP target varied for fiscal 2025 based on the position, as follows:

Target Total Cash Compensation – Fiscal 2025⁽¹⁾ 

	Base Salary		Cash Incentive Target (PCP)
Officer		Percent of Target Total Cash Compensation		Percent of Target Total Cash Compensation	Target Total Cash Compensation
Bryan H. Sayler	$830,500	50%	830,500	50%	1,661,000
Christopher L. Tucker	$616,500	61%	400,700	39%	1,017,200
David M. Schatz	$426,100	67%	213,100	33%	639,200

(1) Amounts shown are annual targets for fiscal 2025; the actual amounts paid are set forth in the Summary Compensation Table.

32 ESCO Technologies Inc. Proxy Statement

The higher at-risk target percentage for the CEO as compared to the other executive officers is based on our at risk philosophy and the greater responsibilities of the CEO. Similarly, the CFO has a higher at-risk percentage as compared to the General Counsel. Near the beginning of each fiscal year, after reviewing our business plans for the fiscal year, the Committee determines the key short-term business metrics on which senior management should focus in order to drive results and approves the cash incentive target for each executive officer. Because of the broad responsibilities of the executive officers, their criteria are tied to Company-wide metrics. The Committee then determines the percentage of the cash incentive target which should be tied to each of the metrics and the performance target for each metric, and approves the threshold and maximum multipliers which will be applied to each of the performance targets to determine the payment under the plan. If performance is below the threshold for a metric, there is no payout for that metric.

Cash Incentive Metrics

During the first quarter of fiscal 2025 the Committee approved two metrics for achievement of the fiscal 2025 PCP incentive targets, based on the annual operating plan reviewed by the Board of Directors. The first metric in 2025 was “Adjusted EPS,” weighted at 70% of the total PCP target opportunity. Adjusted EPS is a non-GAAP financial measure and its target was $4.76 for fiscal 2025. Fiscal 2025 Adjusted EPS of $5.54 equaled GAAP diluted EPS from continuing operations of $4.49 plus $0.31 in transaction costs related to the Maritime acquisition and restructuring costs; $0.31 in Maritime operations, interest and amortization expenses, all of which were excluded because they were not in the target; and $0.43 in VACCO earnings prior to the divestiture which were reported in Discontinued Operations but which were added back because they were in the original target.

The second metric in 2025 was “Adjusted Cash Flow from Operating Activities,” weighted at 30% of the total PCP target opportunity. Adjusted Cash Flow from Operating Activities is a non-GAAP financial measure, and its target was $140.2 million for fiscal 2025. The unadjusted 2025 GAAP Cash Flow from Continuing Operations of $200.4 million delivered the maximum payout, so further adjustments related to VACCO and Maritime cash flow would have increased the amount but not the payout for this metric and are therefore not shown here.

The following table summarizes the targets for the two fiscal 2025 cash incentive metrics, the results achieved, and the actual payouts for 2025. The Committee believes that the selected metrics and the performance benchmarks for each metric, and the threshold and maximum multipliers, provided meaningful incentives for 2025 performance.

2025 PCP Targets and Results

		2025 Benchmarks
Metric	Weight (% of Target Incentive)	Threshold	Target	Maximum	Actual Value Achieved	Actual % of Payout Earned (unweighted)
Adjusted EPS	70%	$3.81	$4.76	$5.47	$5.54	200%
Adjusted Cash Flow from Operating Activities (millions)	30%	$112.2	$140.2	$161.2	$200.4(2)	200%

The Summary Compensation Table on page 41 reflects the actual payouts to the executive officers under the PCP for fiscal 2025.

Proxy Statement ESCO Technologies Inc. 33

Changes to Cash Incentive Metrics for Fiscal 2026

In line with its practice in recent years, the Committee determined to allocate 100% of the executive officers’ cash incentive compensation opportunity to the PCP, and approved the following performance criteria for fiscal 2026:

● Adjusted EPS, weighted at 70% of the total target opportunity; and

● Adjusted Cash Flow from Operating Activities, weighted at 30% of the total target opportunity.

As in 2025, the potential cash incentive compensation for fiscal 2026 will range from 0 to 2.0 times the target opportunity for both Adjusted EPS and Adjusted Cash Flow from Operating Activities, depending on actual 2026 performance.

Long-Term Equity Incentive Compensation

The Company’s annual LTI award program consists of a combination of performance-based share unit (PSU) awards and time-vested restricted share unit (RSU) awards. For fiscal 2025 the Committee determined to shift the mix of the LTI awards toward the performance-based PSUs rather than being divided equally between the PSUs and the RSUs as they were in in prior years, and it assigned 70% of the total LTI target value to the PSUs and 30% to the RSUs. For fiscal 2025, both the PSU and RSU grants were approved in the first quarter of the fiscal year.

We do not coordinate LTI grants with the release of material non-public information. Company-wide equity grants, including equity grants to our executive officers, are made at regular meetings of the Compensation Committee. We also do not grant stock options or other awards which require a payment by the recipient in order to realize the value of the award.

The target number of shares in each RSU and PSU award equals the Committee-approved target values divided by the average trading price of the Company’s stock over the last 15 trading days before the effective award date. The actual payout of the RSUs and PSUs will be in shares, whose value at the time of payout may be greater or less than the target values. For an award to vest, the recipient must generally be continuously employed by the Company from the award date through the vesting date.

For the executive officers, the numbers of RSUs granted and the PSU threshold, target and maximum numbers of shares payable according to the performance criteria, were as follows:

	RSU Target Values as of Grant Date	Number of RSUs Granted	PSU Target Values as of Grant Date	PSU Payout Potential (Shares)
Officer				Threshold (50%)	Target (100%)	Maximum (200%)
Bryan H. Sayler	$810,000	6,226	$1,890,000	7,263	14,526	29,052
Christopher L. Tucker	231,180	1,777	539,420	2,073	4,146	8,292
David M. Schatz	127,830	982	298,270	1,146	2,292	4,584

Restricted Share Units (RSUs)

RSUs are time-vested awards. The terms of the fiscal 2025 awards were similar to those granted in fiscal 2024, vesting over a period of approximately three years, in three equal portions approximately 12, 24 and 36 months after the grant date; accordingly, for the fiscal 2025 awards, vesting will occur on the last NYSE trading days in November 2025, 2026 and 2027, at which time they will be converted into a like number of shares of Company common stock, and such shares will be paid out to the participant (after statutory tax withholdings) on the following business day.

34 ESCO Technologies Inc. Proxy Statement

Performance Share Units (PSUs)

Other than the specific share amounts and performance goals, the terms of the fiscal 2025 PSUs were substantially similar to those awarded for fiscal 2024, including that the awards are subject to the Company’s Clawback Policy (see Clawback Policy on page 40). The fiscal 2025 PSUs will vest after a three-year performance period beginning with fiscal 2025 and ending with fiscal 2027, on the day in the first quarter of fiscal 2028 on which the HRCC approves and certifies the extent to which the applicable performance goals have been achieved. To the extent earned, the vested awards will be converted into a number of shares of Company common stock based on achievement of the performance goals. The award distribution in shares may be less than or greater than the number of PSUs awarded, within certain specified threshold and maximum limits. Straight-line interpolation will be used to score between threshold, target and maximum performance levels. For the fiscal 2025 PSU awards, the Committee continued to align the performance measures with shareholders by continuing the use of EBITDA as a performance measure with a 60% weighting and Return on Invested Capital (ROIC) as a performance measure with a 40% weighting, and continuing the use of relative Total Shareholder Return (rTSR) as a potential modifier as described below:

EBITDA Performance Goals – 60% of PSU Award Value

		Below Threshold	Threshold	Target	Maximum
Cumulative Company EBITDA for the three year performance period(1)	Performance Level	<85% of EBITDA target	85% of EBITDA target	$713.2 million	130% of EBITDA target
	Payout(2)	0%	50%	100%	200%

ROIC Performance Goals – 40% of PSU Award Value

		Below Threshold	Threshold	Target	Maximum
Company ROIC for 2027(3)	Performance Level	<85% of ROIC target	85% of ROIC target	12% for FY2027	130% of ROIC target
	Payout(2)	0%	50%	100%	200%

(1) The EBITDA target was set by the Committee to represent a challenging performance incentive based on annual percentage increases over actual 2024 EBITDA and is not intended as guidance or a prediction of actual results.

(2) Subject to adjustment as described below.

(3) The ROIC target was set by the Committee to represent a challenging performance incentive and is not intended as guidance or a prediction of actual results.

After applying the above performance metrics, the resulting number of PSUs may be subject to increase or decrease based on the Company’s Total Shareholder Return (TSR) over the performance period compared to the TSR of the companies in a peer group based on the S&P SmallCap 600 Industrials Index. If the Company’s rTSR is below the 25th percentile or above the 75th percentile, the resulting number of shares will be decreased by 20% or increased by 20%, respectively; if the Company’s rTSR is from the 25th percentile to the 75th percentile, no adjustment will be made. In no event will the award payout be greater than 200% of the target.

Changes to Long Term Incentive Compensation for 2026

The 2025 Meridian market assessment indicated that the executive officers’ total direct compensation was lagging the market primarily due to below-market LTI. In response, the Committee significantly increased the total 2026 LTI values as percentages of base salaries, resulting in fiscal 2026 target LTI values as of the grant date of $3,500,000 (389% of base salary) for Mr. Sayler, $960,800 (150% of base salary) for Mr. Tucker, and $556,600 (125% of base salary) for Mr. Schatz.

The fiscal 2026 RSU awards were granted in November 2025; they will vest in three equal portions approximately 12, 24 and 36 months after the month in which they are granted; for the fiscal 2026 awards, vesting will occur on the last trading days in November of 2026, 2027 and 2028.

The fiscal 2026 PSU awards were also granted in November 2025, and after a three-year performance period ending with fiscal 2028, they will vest on the last trading day of the month in which the HRCC approves and certifies the extent to which the applicable performance goals have been achieved. To the extent earned, the vested awards will be converted into a currently undeterminable number of shares of Company common stock, which may be less than or greater than the number of PSUs awarded, within certain specified threshold and maximum limits, depending on the degree to which the Company has achieved one or more specified performance goals. If the performance is less than the threshold goal for a particular performance measure, there will be no payout of that portion of the PSUs dependent on that measure.

Other Compensation Elements

Perquisites

The Company also provides limited perquisites to the executive officers, which currently include financial planning and an annual physical. The Committee annually reviews the types and value of the perquisites provided to the executive officers as part of its overall review of executive compensation. The Committee determined the perquisites paid in fiscal 2025 to be reasonable.

Certain of these perquisites are treated as taxable income. We do not reimburse our executive officers for the income taxes due on these perquisites (“tax gross-ups”), and beginning in fiscal 2023 we ceased providing auto allowances and country club benefits for our executive officers other than country club initiation fee benefits for Mr. Sayler and Mr. Tucker based on their employment terms at hire.

Retirement Benefits

Like our other employees, the executive officers are eligible for retirement benefits provided through our 401(k) Plan. See Pension Benefits on page 44.

Severance Plan

Severance provisions in the event of a change of control benefit a company by allowing executives who are parties to such arrangements to focus on continuing business operations and the success of a potential business combination rather than seeking alternative employment, thereby providing stability to a corporation during a potentially uncertain period. Accordingly, the Company has adopted a Severance Plan which prescribes the compensation and benefits to be provided in the event of a change of control to certain executives, including the CEO and the other executive officers.

Our change of control arrangements are designed to provide executives with severance payments and certain other benefits in the event that their employment is terminated in connection with a change of control transaction. The Severance Plan includes a “double trigger,” which means that it provides severance benefits only if there is both (1) a change of control of the Company, and (2) the Company (or any successor) terminates the employee’s employment without cause within 36 months following a change of control, or the employee terminates his or her employment for good reason within 36 months following a change of control, or the Company terminates the employee’s employment within 90 days before a change of control at the request of a third party who, at such time, had taken steps reasonably calculated to effect the change of control.

For purposes of the Severance Plan, “change of control” means any of the following (subject to the specific definitions in the Severance Plan): (i) the acquisition by any person or group of at least 20% of the then-outstanding shares of the Company’s common stock; or (ii) a change in a majority of the members of the Board of Directors that is not approved by the incumbent Board; or (iii) the approval by the shareholders of either a reorganization, merger or consolidation after which the shareholders will not own at least a majority of the Company’s common stock and voting power, or a liquidation or dissolution of the Company, or the sale of all or substantially all of the Company’s assets.

Proxy Statement ESCO Technologies Inc. 37

If the Severance Plan is triggered, the executive will be entitled to all accrued but unpaid compensation, a pro rata cash bonus for the year of separation and benefits through the date of separation, as well as a lump sum cash payment which is designed to replicate the cash compensation (base salary and cash incentive), plus certain benefits, that the executive would have received had he or she remained employed for two years. These payments and benefits would only be paid as a result of a double-trigger event. The determination of the appropriate level of payments and benefits to be provided in the event of a change of control termination involved consideration of several factors. The two-year multiple was determined based on a survey of the Company’s peers at the time the Severance Plan was adopted by the Company, and is deemed to be reasonable. The Committee considered that a high-level executive, who is more likely to lose his or her job in connection with a change of control than other employees, may require more time than other employees in order to secure an appropriate new position, and, unless that executive was provided with change of control benefits, he or she may be motivated to start a job search early if a change of control is anticipated, to the detriment of the Company. Thus, the existence of the Severance Plan provides an incentive for the executive to remain with the Company until a change of control actually occurs. In addition, payments are not provided under the Severance Plan unless there has been not only a change of control but also a qualifying termination of employment, thus providing an acquirer the opportunity to retain the Company’s management team during or after a transition period.

For further information about the Severance Plan, and a sample calculation of the cash compensation and benefits to be provided to our executive officers under the Severance Plan, based on certain stated assumptions, see Potential Payments Upon Termination or Change in Control beginning on page 45.

In addition, pursuant to the executive officers’ severance agreements as well as their LTI award agreements, in the event of a change of control, all LTI awards are to be assumed by the acquirer or successor entity and converted to an equivalent agreement. If for any reason the awards will not or cannot be assumed, they will be paid out in cash.

Employment Agreements

We have entered into employment and compensation agreements with each of our executive officers. The agreements provide for payment of an annual base salary, participation in our cash incentive plans, eligibility for participation in our LTI plans and benefit plans and programs applicable to senior executives, and continuance of certain perquisites. For more information about the terms of these agreements, including specifics regarding the cash compensation and benefits provided in the event of a qualifying separation, and for a sample calculation based on certain stated assumptions, see Employment Agreements on page 44, and Potential Payments Upon Termination or Change in Control beginning on page 45.

The Compensation Committee periodically assesses the reasonableness of the executive officers’ employment agreements to consider whether any changes are appropriate.

Deferred Compensation Plan for Selected Employees

Effective in 2025, the Company established the ESCO Technologies Inc. Deferred Compensation Plan (the Plan), under which its executive officers and other selected management or highly compensated employees may elect in advance to defer receipt of from 5% to 75% of their base salary and/or from 5% to 100% of their at-risk compensation, including PCP payouts, RSUs and PSUs. Deferrals may be for a period or periods specified in advance by the participant, or until the participant’s employment terminates, if earlier, and distribution will be accelerated in certain circumstances, including a change in control of the Company. For fiscal 2025, Mr. Sayler elected to defer 10% of his PCP payment, which was paid in November 2025.

Deferred amounts are credited to the participant’s deferred compensation account either in cash or in common stock equivalents depending on the nature of the deferred compensation, and receipt is subject to any vesting requirements specified in the compensation award. Deferrals of cash-based compensation (such as base salary and PCP payouts) are measured and paid in dollars and credited with earnings based on the earnings of one or more notional investment options offered by the Company and elected by the participant; however, those options are provided solely as measuring devices, and at no time will the participant have any interest in any such investment option. Cash deferrals may not be allocated to Company common stock. Deferrals of share-based compensation (such as RSUs and PSUs) are credited to the participant’s

38 ESCO Technologies Inc. Proxy Statement

deferred compensation account as a like number of units, with each unit equal in value to one share of Company common stock. Cash dividends paid on a number of shares of Company common stock equal to the number of deferred units which are vested will be paid in cash as provided in the equity compensation plan under which the units were granted.

Limit on Deductibility of Certain Compensation

Section 162(m) of the Internal Revenue Code prohibits publicly held companies, including the Company, from deducting salaries and other compensation paid to an executive officer to the extent that the total exceeds $1 million during the tax year. Certain compensation based upon the attainment of performance goals set by the Compensation Committee was formerly able to qualify for an exclusion from this limitation, but this exclusion has been eliminated. However, the Committee intends to continue its practice of utilizing shareholder-approved metrics for our cash incentive plans when appropriate, although it reserves the right to use other award provisions that are tailored to achieving our financial and business objectives if it determines that the awards and performance metrics are appropriate and consistent with our business needs.

Stock Ownership Guidelines

The Compensation Committee has established stock ownership guidelines for the executive officers. The guidelines set the minimum level of ownership at a multiple of annual base salary as follows:

Title	Multiple of Base Salary
CEO and President	5x
Other Executive Officers	3x

Executive officers are expected to be in compliance with the ownership guidelines within five years of their appointments, and they are required to hold 100% of all after-tax stock distributions received from compensation awards until the guideline amounts are reached and thereafter as needed to maintain ownership of at least the guideline amounts. All of our executive officers currently exceed the ownership guidelines.

Insider Trading Policy; Anti-Hedging and Anti-Pledging Policies; Timing of LTI Grants

Our Insider Trading Policy prohibits any employee from trading in Company securities while in possession of material non-public information. In addition, the Insider Trading Policy strictly prohibits our directors, officers and employees from engaging in transactions in Company securities involving puts, calls or other derivative securities on an exchange or in any other organized market, selling Company securities “short”, or entering into hedging or similar arrangements (such as exchange funds) involving Company securities. The Insider Trading Policy also prohibits our directors, officers, corporate office employees, and other designated employees in management positions from pledging Company securities as collateral for a loan or holding Company securities in a margin account. These policies are intended to ensure that the executive officers, as well as other Company personnel in positions of authority, cannot offset or hedge against declines in the price of the Company stock they own or have a personal interest in the price of their shares which may be different from the interests of other shareholders generally. A clickable link to the Insider Trading Policy is located at Exhibit 19 in the Exhibit Index to our 2025 Annual Report on Form 10-K on file with the SEC.

We do not coordinate LTI grants with the release of material non-public information. Company-wide equity grants, including equity grants to our executive officers, are made at regular meetings of the Compensation Committee. We also do not grant stock options or other awards which require a payment by the recipient in order to realize the value of the award.

Proxy Statement ESCO Technologies Inc. 39

Clawback Policy

Our Code of Conduct reaffirms the importance of high standards of business ethics. Adherence to these standards by all employees is the best way to ensure compliance and secure public confidence and support. All employees are responsible for their actions and for conducting themselves with integrity. Any failure on the part of any employee to meet any of the standards embodied in this Code will be subject to disciplinary action, including potential dismissal.

We adopted a robust Compensation Recovery Policy (Clawback Policy) in 2010, and in October 2023 we adopted a Supplement to the Clawback Policy designed to comply with the enhanced clawback-related listing standards adopted in 2023 by the NYSE. The Clawback Policy provides that when appropriate, and in accordance with applicable law, the Company may recover any “Recoverable Compensation” received during a prescribed period of up to three years if an executive or other senior officer of the Company or any of our affiliates:

● Engages in intentional misconduct resulting in a financial restatement or in any increase in his or her incentive or equity income, or

● Engages in activity that competes with the Company or its affiliated companies, or

● Solicits customers or hires or assists anyone else in soliciting or hiring employees of the Company or its affiliates after termination of employment or engages in the unauthorized disclosure or use of the Company’s confidential information resulting in harm to the Company or its affiliates, in any case in violation of agreements entered into by such employee prohibiting such actions.

“Recoverable Compensation” is defined to include any equity and incentive compensation received, earned or distributed to or for the benefit of an executive or senior officer, including amounts and shares under any equity or compensation plan or employment agreement. The Clawback Policy specifies that to the extent compensation is recovered from an individual as a result of a financial restatement such amounts will be excluded from “Recoverable Compensation.”

As supplemented, the Clawback Policy also provides in the event the Company is required to prepare an accounting restatement of its financial statements due to the Company’s material noncompliance with any financial reporting requirement under the federal securities laws, the Board shall require prompt reimbursement or forfeiture of any excess Incentive-Based Compensation, as defined in the Supplemental Clawback Policy, received by a Company executive during the three completed fiscal years immediately preceding the date on which the Company is required to prepare an accounting restatement, in addition to any transition period (that results from any change in the Company’s fiscal year) within or immediately following such three completed fiscal years.

Recoupment and clawback provisions are included in all equity awards and performance compensation plan agreements for certain participants. The Clawback Policy does not prevent us from taking other actions as appropriate, if warranted, based on the misconduct outlined above.

A clickable link to the Clawback Policy, including the 2023 Supplement, is located at Exhibits 97.1 and 97.2 in the Exhibit Index to our 2025 Annual Report on Form 10-K on file with the SEC.

During fiscal 2025, there was no financial restatement which would have required action under the Clawback Policy to recover any Recoverable Compensation, and at the end of fiscal 2025 there was no outstanding balance of Recoverable Compensation resulting from a financial restatement in any prior year.

1 Represent the threshold, target and maximum cash incentive opportunities awarded for fiscal 2025 under the PCP. If performance according to a specific performance measure is less than that necessary to achieve the threshold payout, the payout will be zero for that measure. Actual amounts earned were based on fiscal 2025 results and are reported in the column captioned Non Equity Incentive Plan Compensation in the Summary Compensation Table; these amounts were paid out in fiscal 2026. For more information, see Principal Elements of Compensation – Cash Incentive Plans in the Compensation Discussion and Analysis section.

2 Represent the threshold, target and maximum equity incentive opportunities for the PSUs awarded for fiscal 2025 under the Company’s Long-Term Incentive Compensation program. If performance according to a specific performance measure is less than that necessary to achieve the threshold payout, the payout will be zero for that measure. The actual incentive payout will be in shares of common stock based on Company performance over a three-year performance period and will not be determinable until after the close of the performance period. For more information, see Principal Elements of Compensation – Long-Term Equity Incentive Compensation in the Compensation Discussion and Analysis section.

1 Each RSU represents the right to receive one share of Company common stock if the recipient remains continuously employed by the Company until the vesting date. RSUs awarded prior to 2023 will vest in their entirety approximately 3¹/₂ years after the effective award date, except that Mr. Tucker’s February 3, 2023 RSUs will vest on November 5, 2025. RSUs awarded in 2023 will vest in three equal tranches approximately 18, 30 and 42 months after the effective award date, on the last trading days in November of 2024, 2025 and 2026. RSUs awarded in 2024 will vest in three equal tranches approximately 12, 24 and 36 months after the effective award date, on the last trading days in November of 2025, 2026 and 2027. Vested shares will be issued to the participant (less a number of shares having a value equal to the amount of required tax withholdings) on the following business day.

2 Based on the NYSE closing price of the Company’s common stock of $211.11 on September 30, 2025, the last NYSE trading day of the Company’s 2025 fiscal year.

3 Represents the number and value of the shares issuable if Company performance over the three-year performance period meets the threshold required to earn a minimum non-zero payout for each of two performance components. However, because performance below either threshold will result in a zero payout for that component, the minimum payout is actually zero. The actual payout will not be determinable or estimable until after the close of the performance period. For more information, see Principal Elements of Compensation – Long-Term Equity Incentive Compensation in the Compensation Discussion and Analysis section.

4 Includes cash dividend equivalents accrued on RSUs awarded beginning in fiscal 2023 and on PSUs beginning in fiscal 2024. On each regular quarterly dividend date occurring from the award date to and including the vesting date, the Company accrues for the benefit of the recipient an amount in cash equal to the cash dividend which would have been paid on a number of shares of Company common stock equal to (a) in the case of RSUs, the number of unconverted (unvested) RSUs, and (b) in the case of PSUs, the number of shares corresponding to the target payout. The amount accrued with respect to each vested portion of the award will be paid out in cash at the time that portion of the award is distributed in shares; but, if or to the extent the award does not vest, or is not earned, or for any other reason is not distributed, a like portion of the accrued amount will be cancelled and not paid.

PENSION BENEFITS

401(k) Plan

We have not maintained a defined benefit retirement plan since 2020. We offer an Employee Savings Investment Plan, a defined contribution plan under section 401(k) of the Code (401(k) Plan), to substantially all United States employees including our executive officers. The 401(k) Plan provides for a Company cash match at a rate of 100% of the contributions by each employee up to 3% of the employee’s eligible compensation, and 50% of any additional contributions by the employee up to 5% of the employee’s eligible compensation, subject to Code contribution limits. The amounts of the Company’s cash match for the accounts of the executive officers in fiscal years 2023, 2024 and 2025 are listed in footnote (3) to the Summary Compensation Table, under the heading Defined Contribution Savings Plan Company Contributions.

EMPLOYMENT AGREEMENTS

We have written employment and compensation agreements with each of our executive officers. The agreements provide for a base salary, which is subject to annual review by the Compensation Committee but may not be decreased, and an annual cash incentive opportunity in accordance with our cash incentive program. The executive officers are entitled to participate in LTI awards and other compensation programs as determined by the Compensation Committee, as well as in all Company employee benefit programs applicable to senior executives, and the Company agrees to provide certain perquisites, including financial planning and outplacement assistance.

The agreements provide that following an initial term (which in each case has now elapsed), they will automatically renew for successive one-year periods unless a specified notice of non-renewal is given by the Company or the executive.

The agreements give each party certain termination rights, with post-termination compensation and benefits payable to the executive officer, if any, depending on the reasons for the termination, such as whether the termination is with or without Cause, as defined in the agreements. The following section, Potential Payments Upon Termination or Change in Control, describes the compensation and benefits payable to the current executive officers upon termination of their employment for various reasons.

44 ESCO Technologies Inc. Proxy Statement

The employment agreements prohibit the executives from disclosing confidential information or trade secrets concerning the Company, and for a period of two years from soliciting employees of the Company and from soliciting customers or distributors of the Company. The agreements also require the executive officers to provide limited consulting services on an as-requested basis following termination.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Payments/Benefits Upon Change in Control

Severance Plan

We have established a Severance Plan covering the executive officers. Under the Plan, following an occurrence of a Change of Control as defined in the Severance Plan (see Other Compensation Elements – Severance Plan in the Compensation Discussion and Analysis section), each of the executive officers will be entitled to be employed by the Company for a period of three years following the Change of Control, unless terminated earlier in accordance with the Severance Plan. During this employment period the executive officer will: (i) be paid a minimum base salary equal to his or her base salary prior to the Change of Control, (ii) be paid a minimum annual bonus equal to the latest target cash incentive opportunity approved by the Compensation Committee prior to the effective date of the Change of Control (the “Current Cash Incentive Target”), (iii) continue to receive the employee benefits to which he or she was entitled prior to the Change of Control, and (iv) receive annually the value (determined as described under Incentive Plan Awards below) of the last LTI awards issued to him or her prior to the Change of Control, which value may be paid either in cash or in publicly traded stock of the entity which acquired the Company in the Change of Control.

If we terminate the executive officer’s employment during this three-year employment period other than for death, disability or Cause as defined in the Severance Plan, or if the executive officer terminates his or her employment during the employment period following certain specified actions by us (Good Reason), such as materially failing to comply with the provisions of the Severance Plan, a material diminution in his or her authority, duties or responsibilities or base salary, or requiring him or her to relocate, he or she will be entitled to receive, among other things, a cash lump sum equal to the aggregate of (i) any unpaid current base salary, (ii) a bonus equal to the Current Cash Incentive Target, prorated for a partial year, and (iii) an amount calculated by multiplying two times the sum of the current annual base salary and the Current Cash Incentive Target. In addition, he or she will receive the continuation of his or her employee benefits for two years.

We may amend the Severance Plan, but no amendment adverse to the rights of an executive officer will be effective unless we have given the executive officer notice of the amendment at least one year before a Change of Control occurs.

Proxy Statement ESCO Technologies Inc. 45

Long-Term Incentive Plan Awards

The terms of our RSU and PSU awards in effect at September 30, 2025 provide that upon a Change of Control (defined in the awards substantially the same as in the Severance Plan) the awards will be assumed by the acquirer or successor entity and converted to an equivalent agreement. If for any reason the awards will not or cannot be assumed, they will be paid out in cash.

Payments/Benefits Upon Death or Disability

If the executive officer’s employment were to be terminated because of death or disability, under the executive officer’s employment agreement with the Company the executive officer (or his or her beneficiaries) would receive benefits under the Company’s disability plan or the Company’s life insurance plans, as applicable.

With respect to RSU and PSU awards in effect at September 30, 2025, the Committee may, in its sole discretion, make full, pro-rata, or no share distributions, as it may determine, to an executive officer in the event of disability, or to the executive officer’s surviving spouse or beneficiary in the event of death.

Payments/Benefits Upon Termination by the Employee With Good Reason or by the Company Without Cause

The executive officers’ employment agreements provide that if we were to terminate the executive officer’s employment prior to a Change of Control other than for cause, death or disability or if the executive officer were to resign following certain actions by us defined in the agreements as “Good Reason,” including our materially failing to comply with the agreement, materially reducing the executive’s responsibilities or requiring the executive to relocate, we would be required to continue to pay the executive officer’s base salary and cash incentive for two years following termination; however, the executive officer could elect to receive each of these payments in a lump sum on or about March 15 of the calendar year following the calendar year in which the termination occurs. In addition, certain employee benefits would continue after the termination, the executive officer’s accelerated but unvested RSU and PSU awards would become fully vested and the underlying shares would be distributed, subject to and in accordance with the terms of the Omnibus Plan. These payments and benefits would be conditioned upon the executive officer not soliciting our employees, customers or distributors for a period of two years after termination. In addition, the executive officer would be required to execute our standard severance agreement and release.

Payments/Benefits Upon Termination by the Employee Without Good Reason

If the executive officer were to resign without Good Reason, the executive officer would not be entitled to payment of continued compensation or benefits, and all outstanding RSU and PSU awards would be forfeited.

Payments/Benefits Upon Termination by the Company for Cause

If we were to terminate the executive officer’s employment for Cause, under the employment agreement the executive officer would not be entitled to payment of continued compensation or benefits, and all outstanding RSU and PSU awards would be forfeited.

Incremental Compensation in the Event of Termination as a Result of Certain Events

The following tables reflect the additional compensation and benefits to be provided to the executive officers in the event of a termination of employment at, following, or in connection with a Change of Control or for the other listed reasons. The amounts shown assume that the termination was effective as of the close of business on September 30, 2025, the end of our 2025 fiscal year. No outstanding PSU awards were earned or vested as of September 30, 2025. The actual amounts to be paid would be determinable only at the time of the actual termination of employment.

Footnotes to the Above Three Tables

1 Represents three months’ base salary, which we have the discretion to provide to the executive officers in order to cover the waiting period under our group long-term disability insurance policy.

2 As calculated under the terms of the executive officer’s employment agreement. The amount shown represents the annual base salary in effect at September 30, 2025 multiplied by two.

3 As calculated under the terms of the Severance Plan. The amount shown is in lieu of any annual cash incentive for fiscal 2025 which would have otherwise been paid except for the termination.

4 As calculated under the terms of the executive officer’s employment agreement.

5 As calculated under the terms of the Severance Plan.

6 Represents the value of shares that would be distributed upon the occurrence of a change in control and in the event the awards are not assumed by the successor company, based on the average NYSE closing price of our common stock of $211.56 for the ten trading days preceding and including September 30, 2025, the last trading day of our 2025 fiscal year, pursuant to the Severance Plan and the award agreements. These amounts would become payable to the executive officer even if the officer’s employment were not terminated in connection with the change in control. See Payments/ Benefits Upon Change in Control – Long-Term Incentive Plan Awards on page 46.

7 The amounts shown represent the projected cost to continue benefits in accordance with the executive officer’s employment agreement and the provisions of the Severance Plan. Included in Total Benefits are broad-based benefits (health insurance, life and disability premiums) and financial planning. In the case of “Termination by Employee for Good Reason or by Employer Without Cause,” Total Benefits also include an estimated outplacement fee of $20,000.

8 Under Internal Revenue Code Section 280G, certain payments made to an executive officer in the event of a Change in Control are subject to a “golden parachute” excise tax under Code section 4999. The Severance Plan provides that if any compensation paid to the executive officer upon a Change in Control causes this excise tax to be imposed, the compensation would be reduced if and to the extent that the reduction would create a more favorable net-after-tax benefit to the executive officer. Based on the calculations prescribed under section 280G as applied to the amounts shown in the table, the executive officer would be subject to this excise tax in the event of a Change in Control, and therefore the officer’s compensation would be reduced by the amount shown.

PAY RATIO DISCLOSURE

CEO Pay Ratio

Pursuant to Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and the implementing regulations of the SEC, we are providing the following information about the relationship between the total annual compensation of our CEO, Mr. Sayler, and the median total annual compensation of our employees.

As reported in the Summary Compensation Table on page 41, Mr. Sayler’s 2025 total annual compensation was $5,586,139. The 2025 median total annual compensation of all of our employees who were employed as of August 1, 2025 (the Determination Date), other than Mr. Sayler, was $71,384, resulting in a pay ratio of 78:1.

Calculation Methodology

As of the Determination Date, our total worldwide employee population consisted of 3,468 employees, excluding the CEO. This included all full-time, part-time and temporary employees as well as employees on leaves of absence. Although the SEC regulations permit companies to exclude a limited number of non-U.S. employees, we did not use this exclusion.

The SEC regulations require the identification of the median compensated employee using a “Consistently Applied Compensation Measure” (CACM). The CACM used consisted of base salary or wages, overtime, target bonus and commissions as of the Determination Date. This compensation was annualized to cover the full 2025 fiscal year, as was the compensation of new hires. For international employees, their compensation was converted to U.S. dollars using the applicable foreign exchange rate as of the Determination Date.

After identifying the median compensated employee, that employee’s total annual compensation was calculated consistent with the methodology used for determining the CEO’s total annual compensation for the Summary Compensation Table.

The pay ratio reported above is our reasonable estimate calculated in a manner consistent with SEC regulations and the methodology described above. However, the SEC rules for identifying the median compensated employee and calculating the pay ratio allow companies to adopt a variety of methodologies, to apply exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices and employee populations. Other companies may calculate their pay ratio using a methodology or estimates and assumptions which differ from those we used. Therefore, the pay ratio reported above may not be comparable to the pay ratio reported by other companies, including those in our peer group.

1 Bryan H. Sayler has served as the Company’s PEO (Principal Executive Officer) since the second quarter of fiscal 2023.

2 Victor L. Richey served as the Company’s PEO during fiscal 2021, fiscal 2022 and the first quarter of fiscal 2023.

3 The Company’s non-PEO executive officers for fiscal 2022 through 2025 were Christopher L. Tucker, Senior VP & CFO, and David M. Schatz, Senior VP, General Counsel & Secretary. In fiscal 2021, Mr. Tucker succeeded Gary E. Muenster as an executive officer, and Mr. Schatz succeeded Alyson S. Barclay as an executive officer. Accordingly, there were two persons serving as non-PEO executive officers at all times during these years.

4 The following amounts were deducted from or added to Summary Compensation Table total compensation in accordance with the SEC-mandated adjustments to calculate Compensation Actually Paid to our principal executive officer (PEO) and the average Compensation Actually Paid to our non-PEO executive officers. The fair value of equity awards was determined using methodologies and assumptions developed in a manner substantively consistent with those used to determine the grant date fair value of such awards. In calculating the year-end fair values of equity awards, the assumptions made did not differ materially from the assumptions made in calculating the grant date fair values of such awards.

5 The Peer Group TSR set forth in this table utilizes the S&P SmallCap 600 Industrials Index, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended September 30, 2025. The comparison assumes $100 was invested for the period starting September 30, 2021 through the last day of the subsequent fiscal years, in the Company and in the S&P SmallCap 600 Industrials Index, respectively. Historical stock performance is not necessarily indicative of future stock performance.

6 We determined EPS to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and the other executive officers in 2025. This performance measure may not have been the most important financial performance measure for one or more of fiscal years 2021 through 2024 and we may determine a different financial performance measure to be the most important financial performance measure in future years.

Proposal 3:

APPROVAL OF AMENDMENT TO THE COMPANY’S

EMPLOYEE STOCK PURCHASE PLAN

The Board of Directors recommends a vote FOR this Proposal.

The Company’s Board of Directors has declared it to be advisable and in the best interests of the Company and its shareholders, and therefore recommends that the shareholders approve, an amendment to Section 7(b) of the Company’s Employee Stock Purchase Plan, as described below (the “Proposed Amendment”).

PRINCIPAL FEATURES OF THE PLAN

The Plan was adopted by the Board of Directors of the Company on April 28, 1992. It has been amended and restated numerous times, most recently in November 2024. The purpose of the Plan is to provide a convenient method by which eligible employees of the Company and its designated domestic subsidiaries, who choose to do so, may purchase shares of the Company’s common stock. The administrator and Trustee of the Plan is Computershare, Inc., which is also the Company’s transfer agent. All costs and expenses of administering the Plan, including the fees of the Trustee, are paid by the Company.

Eligibility and Participation

All current and future employees of the Company and its current domestic and Canadian subsidiaries are eligible to participate in the Plan. A subsidiary hereafter acquired by the Company may elect to permit its employees to participate in the Plan subject to the approval of the Company’s Chief Executive Officer or any other Senior Corporate Officer of the Company to whom the Chief Executive Officer has delegated such authority.

Participation in the Plan is entirely voluntary. Upon written application by any eligible employee to the Trustee, on a Company-approved form, the Trustee will open a Plan account for the employee. Eligible employees for whom accounts are opened and maintained in accordance with the terms of the Plan are referred to as “participants”.

Contributions by Participants

Participants may make contributions to the Plan only through payroll deductions. By completing and submitting a Company-approved form, participants may authorize the Company to make deductions from their “Compensation” as defined in the Company’s 401(k) Plan, which generally includes all cash compensation but excludes payments under stock-based plans, severance payments, reimbursements and payments more than 2¹/₂ months after termination of employment or the end of the plan year, to be applied to the purchase of Company common stock under the terms of the Plan. Deductions authorized for such purpose must be whole percentages of eligible compensation, not less than one percent (1%) nor more than ten percent (10%).

A participant may cease making contributions to the Plan at any time, but the shares allocated to the participant’s account will remain in the Plan until they are withdrawn by the participant; however, if the participant later wishes to resume making contributions to the Plan the participant must complete a new Plan Participation/Election Form.

As of September 30, 2025 the Trustee held a total of approximately 128,154 shares of Company common stock in the Plan for a total of 838 participant accounts, of whom 630 were active participants with payroll deduction elections currently in effect.

Proxy Statement ESCO Technologies Inc. 55

Purchase and Allocation of Shares

The Company forwards the participants’ payroll deduction contributions, together with the Company’s matching contributions described below, to the Trustee monthly, and the Trustee uses the contributions to purchase shares of Company common stock. Brokerage costs incurred in the purchase are charged pro rata to the participants’ accounts and increase the participants’ cost basis in their shares.

The Trustee may purchase shares either on the open market or in private transactions, but no private transactions may be at a price greater than the then-market price on the New York Stock Exchange. Following each stock purchase, the Trustee allocates the purchased shares to the participants’ accounts pro rata according to their respective contributions to the purchase price. The Trustee may not purchase shares from the Company.

Withdrawal from the Plan; Sale of Shares

A participant may from time to time elect to withdraw a number of whole shares from the participant’s account, in which case the shares are transferred to an individual account in the name of the participant, to the participant’s brokerage account, or otherwise as the Company may permit. Alternatively, the participant may request the Trustee to sell a number of whole shares in the participant’s account and remit the cash proceeds to the participant, less any commission charged by the Trustee.

Company Matching Contributions

Section 7(b) of the Plan permits the Company to make matching contributions to the Plan in cash up to a maximum of 20% of the employees’ contributions. These matching contributions are used by the Trustee to purchase additional shares, which are allocated proportionately to the participants’ accounts as described above. Since 2004, the match percentage has been the maximum of 20%. Matching contributions allocated to a participant’s account constitute taxable income to the participant and are deductible by the Company as a compensation expense. In fiscal 2025, the Company made pre-tax contributions of approximately $1,098,000 to the Plan to match approximately $5,490,000 in employee contributions. However, because future Company matching contributions are dependent on the number of participants and their individual elections as well as approval of the proposed increase in the maximum number of matching shares, and because the value of a participant’s Plan account depends on the value of the underlying Company common stock, the future amounts or value which any individual or group of employees may receive under the Plan is not determinable.

Current Limitation; Effect

In 2003 the Plan was amended to place a cap of 200,000 on the total number of shares which could be purchased thereafter with Company matching contributions; as a result, the Company must periodically seek approval from its shareholders to increase the number of shares that can be purchased with Company matching contributions. At the February 2019 Annual Meeting, the Company’s shareholders overwhelmingly approved an increase in the cap to the current number of 275,000 shares.

As of September 30, 2025 a total of 255,014 shares had been purchased after 2003 with Company matching contributions, of which 16,077 shares had been purchased in the previous 24 months. The Company estimates that, based on current employee participation rates and Company stock prices, the 275,000 share cap may be reached some time during fiscal 2027, at which time, unless the cap is increased as proposed by the Proposed Amendment, the Company will not be able to make further matching cash contributions to the Plan for the purchase of Company stock. The Company believes that this would greatly diminish the incentive for employees to participate in the Plan and thereby reduce the alignment between the interests of the Company and its employees created by employee ownership of Company shares.

DESCRIPTION OF THE PROPOSED AMENDMENT

Purpose and Text of the Amendment

The Proposed Amendment would amend Section 7(b) of the Plan to increase the number of Company shares which may be purchased with Company matching contributions from 275,000 to 350,000, an increase of 75,000 shares which is the same number as approved in 2019. As in the current Plan, this number is subject to adjustment to reflect stock dividends, stock splits, reverse stock splits and similar matters occurring after the date of the Meeting that affect the number of outstanding shares of Common Stock. The text of the Proposed Amendment is as follows (deletions are in red and lined out, and additions are in blue, in bold font and underlined):

“(b) At the discretion of a Senior Corporate Officer of the Company, the Company or a participating subsidiary may contribute in cash an amount not to exceed twenty percent (20%) of the amounts contributed by participants employed by it or its division or subsidiaries. The Company’s contribution amounts may be separately determined for each of its subsidiaries or divisions. Amounts contributed by the Company or a subsidiary under this Section 7(b) shall be considered as additional compensation to the participants for purposes of applicable income and employment taxes. Commencing October 15, 2003, the total number of shares of Common Stock that may be purchased under the Plan with the Company’s contribution amounts shall not exceed two hundred seventy-five thousand (275,000) three hundred fifty thousand (350,000) shares, which number shall be adjusted to reflect stock dividends, stock splits, reverse stock splits and similar matters occurring after February 5, 2019 the date of the 2026 Annual Meeting that affect the number of outstanding shares of Common Stock.”

A complete copy of the Plan, restated to include the proposed Amendment and to update various references to the effective date of the most recent amendment, is set forth as Appendix A to this Proxy Statement.

Rationale for the Amendment

The Company views the Plan as an important vehicle for Company employees to acquire and hold shares of the Company’s common stock, and thereby more closely align employees’ interests with those of the Company. The cost to the Company of providing the 20% match is approximately $1.1 million per year at current participation rates. Accordingly, Management believes that the Company match offers an important incentive to employees to participate in the Plan at a reasonable cost to the Company, and that its employees’ participation in the Plan would be adversely affected if the Company were no longer able to provide the match.

The Company estimates that, based on the current participation rate and stock price and the possibility of an increasing eligible employee base, the proposed increase will be sufficient to permit Company matching contributions to be made for at least another eight years, through fiscal 2034, at which time it would again seek shareholder approval if it intends to continue the match.

No Dilution

Because the Plan purchases only previously-issued Company shares, and may not purchase shares from the Company, the purchase of shares by the Plan does not increase the number of shares outstanding and therefore does not dilute the interests of the Company’s shareholders, regardless of whether the shares are purchased with employee contributions or with Company matching contributions.

Approval; Effect of Failure to Approve

The Proposed Amendment will become effective upon its approval at the Meeting by a majority of the shares voting on the matter. If the Proposed Amendment is not approved by the requisite vote, then it will not become effective and the number of Company shares that may be purchased under the Plan with the Company’s contribution amounts will remain at its current limit of 275,000 shares. When this limit is reached, most likely during fiscal 2027, the Company will no longer be able to make further matching contributions to the Plan.

The number of shares is subject to adjustment for future changes in capitalization by stock splits, stock dividends and similar events. Does not include shares that may be purchased on the open market pursuant to the Company’s Employee Stock Purchase Plan (ESPP). Under the ESPP, participants may elect to have up to 10% of their current salary or wages withheld and contributed to one or more independent trustees for the purchase of shares. At the discretion of an officer of the Company, the Company or a domestic subsidiary or division may contribute cash in an amount not to exceed 20% of the amounts contributed by participants; however, as of September 30, 2025 the total number of shares purchased with the Company’s matching contributions after October 15, 2003 may not exceed 275,000. As of September 30, 2025, 667,036 shares had been purchased with the Company’s matching funds of which 255,013 were purchased after October 15, 2003.

Details of the directors’ compensation, including elective deferrals and dividend accrual rights, are hereby incorporated by reference to the section captioned “Directors Compensation” beginning on page 21.

AUDIT COMMITTEE REPORT

The Audit and Finance Committee oversees and monitors the Company’s financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process, including the Company’s system of internal controls. In fulfilling its oversight responsibilities, the Committee reviewed and discussed with management the audited financial statements to be included in the Company’s Annual Report on Form 10-K for the year ended September 30, 2025, including a discussion of the quality and the acceptability of the Company’s financial reporting practices and the internal controls over financial reporting.

The Committee reviewed with Grant Thornton, the independent registered public accounting firm which is responsible for expressing opinions on the conformity of those audited financial statements with accounting principles generally accepted in the United States of America and on the Company’s internal control over financial reporting, its judgments as to the quality and the acceptability of the Company’s financial reporting and such other matters as are required to be discussed with the Committee under auditing standards generally accepted in the United States of America. In addition, the Committee discussed with Grant Thornton its independence from management and the Company, including the impact of any non-audit-related services provided to the Company, the matters in that firm’s written disclosures and the letter from Grant Thornton to the Committee pursuant to the applicable requirements of the Public Company Accounting Oversight Board (PCAOB) and the SEC regarding the independent accountants’ communications with the Audit Committee concerning independence, and the other matters required by the PCAOB’s Auditing Standards.

Further, the Committee discussed with both the Company’s internal audit executive and Grant Thornton the overall scope and plans for their respective fiscal 2025 audits. The Committee met periodically with the Company’s internal audit executive and representatives of Grant Thornton, with and without management present, to discuss the results of their respective examinations, their respective evaluations of the Company’s internal controls (including internal controls over financial reporting), and the overall quality of the Company’s financial reporting.

In reliance on the reviews and discussions referred to above, the Committee recommended to the Board of Directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended September 30, 2025 filed with the SEC.

The Committee also appointed Grant Thornton as the Company’s independent registered public accounting firm for fiscal 2026.

For purposes of this Proxy Statement it is deemed to be a beneficial owner of these shares.

SHAREHOLDER PROPOSALS

SEC Rule 14a-19 provides, among other things, that a shareholder desiring to solicit proxies in support of one or more director nominees not nominated by the Company must provide notice of such intent containing the information required by the Rule and postmarked or transmitted electronically to the Company at its principal executive office no later than 60 calendar days prior to the anniversary of the previous year’s Annual Meeting; for the Company’s 2027 Annual Meeting this deadline will be December 1, 2026.

The Company’s Articles of Incorporation require that in order for a shareholder of the Company to formally nominate an individual for election as a director or propose other business at an annual meeting of shareholders, written notice of the nomination or proposal must be given to the Company not less than 60 nor more than 90 days before the meeting; provided that if the Company gives less than 50 days’ notice or prior public disclosure of the date of the meeting, then the shareholder must give such notice not later than ten days after notice of the meeting is mailed or other public disclosure of the meeting is made, whichever occurs first. We intend to give public notice of the date of our 2027 Annual Meeting in connection with the release of our financial results for fiscal 2026, which we expect will occur in mid-November of 2026.

The required advance notice must include certain additional information regarding both the proponent and any prospective nominee useful to the Company in evaluating and responding to the nomination or proposal, and as to proposals other than nominations, a full description of the proposal, including its text, and a description of any agreements or arrangements between the proponent and any other person in connection with the proposal, all as specified in detail in the Company’s Articles of Incorporation and Bylaws. Any prospective director nominees must also complete a questionnaire regarding the background and qualifications of the proposed nominee and any person or entity on whose behalf the nomination is being made, and must represent in writing that the proposed nominee is not, and will not become, a party to any undisclosed voting commitments or compensation arrangements with respect to service as a

director, and will comply with all applicable publicly disclosed corporate governance, conflict of interest, confidentiality and stock ownership and stock trading policies and guidelines of the Company.

The Board may reject any nominations or proposals that are not made in accordance with these procedures or that are not a proper subject for shareholder action in accordance with the provisions of applicable law. The foregoing time limits also apply in determining whether notice is timely for purposes of rules adopted by the SEC relating to the exercise of discretionary voting authority.

The above requirements are in addition to, and are separate from, the requirements of SEC Rule 14a-8 relating to the rights of shareholders to request inclusion of proposals in, or of the Company to omit proposals from, the Company’s proxy statement. However, solely with respect to a proposal, other than the nomination of directors, that a shareholder proposes to bring before an annual meeting of shareholders, the notice requirements set forth in the Company’s Articles of Incorporation and Bylaws will be deemed satisfied by the shareholder if the shareholder has submitted the proposal to the Company in compliance with Rule 14a-8 and the proposal has been included in the Company’s proxy statement for the meeting.

Proposals of shareholders intended to be presented at the 2027 Annual Meeting must be received by the Company not later than August 12, 2026 (120 calendar days before the anniversary of the first mailing of these proxy materials), if the proponent wishes to have them included in the Company’s proxy statement and form of proxy relating to that meeting pursuant to SEC Rule 14a-8. Upon receipt of any such proposal, the Company will determine whether or not to include such proposal in the proxy statement and form of proxy in accordance with SEC regulations governing the solicitation of proxies.

In each case, the notice required to be given to the Company must be directed to the Secretary of the Company, whose address is 645 Maryville Centre Drive, Suite 300, St. Louis, MO 63141-5855 Any shareholder desiring a copy of the Company’s Articles of Incorporation or Bylaws will be furnished one without charge upon written request to the Secretary.

Shareholders may also recommend director candidates to the Governance Committee for consideration as described under Governance Committee on page 17.

TWELFTH AMENDMENT AND RESTATEMENT OF THE ESCO TECHNOLOGIES INC.

EMPLOYEE STOCK PURCHASE PLAN (PROPOSED)

Set forth below is the text of the Company’s Employee Stock Purchase Plan, as restated to include the amendment to Section 7(b) proposed in Proposal 3 – Approval of Amendment to Employee Stock Purchase Plan on page 55; deletions are in red, in italics, and lined out and additions are in blue, in bold font and underlined.

ELEVENTHTWELFTH AMENDMENT AND RESTATEMENT OF THE ESCO TECHNOLOGIES INC.

EMPLOYEE STOCK PURCHASE PLAN

(Incorporating all amendments through November 7, 2024 January 30, 2026)

1. Title: This Plan shall be known as the “ESCO Technologies Inc. Employee Stock Purchase Plan”. ESCO Technologies Inc. (the “Company”) is a Missouri corporation with its principal offices located at 645 Maryville Centre Drive, Suite 300, St. Louis, Missouri 63141.

2. Purpose: The purpose of the Plan is to provide a convenient method by which employees of the Company and certain of its subsidiaries, who wish to do so, may purchase shares of the common stock of the Company (hereinafter referred to as “Common Stock”).

3. Eligibility: A division or subsidiary of the Company may elect to permit its employees to participate in the Plan, subject to the approval of the Chief Executive Officer of the Company or any other Senior Corporate Officer of the Company to whom such authority has been delegated by the Chief Executive Officer of the Company, provided that participation shall be subject to the Company having obtained any necessary permits or authorizations necessary for the offer and/or sale of Common Stock to the participating employees under the Plan. All current and future employees of the units listed in Attachment 1 hereto are eligible to participate in the Plan. Upon the addition or subtraction of a participating subsidiary the Company shall cause Attachment 1 to be appropriately updated, indicating the effective date of the change.

4. Participation:

a. Participation in the Plan shall be entirely voluntary. Upon submission by any eligible employee of a Company-approved Plan Participation and Election Form or by such electronic means as the Company may approve (in whatever form and by whatever method submitted, the “Plan Participation/Election Form”), an account shall be opened with respect to such employee in the name of the employee. Eligible employees for whom accounts are opened and maintained in accordance with the terms of the Plan are herein referred to as “participants.”

b. A participant may not assign or pledge any interest the participant may have under the Plan.

5. The Trustee: The Plan shall be administered by one or more Trustees (herein called the “Trustee,” whether one or more) appointed by an officer designated by the Board of Directors of the Company. The Trustee shall at all times be “an agent independent of the issuer” as defined in Rule 10b-18 under the Securities Exchange Act of 1934 (the “1934 Act”). The Trustee shall have power and authority to establish such procedures as the Trustee shall deem necessary to effect equitably and fairly the provisions and the intent of the Plan.

6. Contributions by Participants:

a. Participants may make contributions to the Plan only through payroll deductions. By completing and submitting a Plan Participation/Election Form, participants may authorize the Company to make deductions from their “Compensation,” as defined in the Company’s Employee Savings Investment Plan (the “401(k) Plan”) to be applied to the purchase of Common Stock of the Company under the terms of the Plan.

64 ESCO Technologies Inc. Proxy Statement

b. Deductions authorized for such purpose shall be whole percentages of Compensation and shall not be less than one percent (1%) nor more than ten percent (10%). The Company may establish rules of uniform application regarding a participant's ability to change the participant’s deduction authorizations.

c. Participants’ contributions shall be included in their gross income for purposes of applicable income and employment taxes.

d. A participant may cease making contributions to the Plan at any time by completing a Plan Participation/Election Form revoking the participant’s payroll withholding authorization. Such cessation shall be effective as promptly as practicable after the participant’s direction to cease withholding is received by the Company’s payroll processing service. In such event the shares allocated to the participant shall remain in the Plan until withdrawn as set forth in Sections 10 or 11 below. If the participant later wishes to resume making contributions to the Plan the participant must submit a new Plan Participation/Election Form.

7. Stock Purchases and Allocation to Participant Accounts: Common Stock purchases under the Plan, and allocation of such Common Stock to the accounts of participants, shall be effected pursuant to the following rules and procedures:

a. The Company shall remit amounts withheld pursuant to payroll authorizations under the Plan to the Trustee on a monthly basis as promptly as practicable after the end of each month.

b. At the discretion of a Senior Corporate Officer of the Company, the Company or a participating subsidiary may contribute in cash an amount not to exceed twenty percent (20%) of the amounts contributed by participants employed by it or its divisions or subsidiaries. The Company’s contribution amounts may be separately determined for each of its subsidiaries or divisions. Amounts contributed by the Company or a subsidiary under this Section 7(b) shall be considered as additional compensation to the participants for purposes of applicable income and employment taxes. Commencing October 15, 2003, the total number of shares of Common Stock that may be purchased under the Plan with the Company’s and its subsidiaries’ contributions shall not exceed two hundred seventy-five thousand (275,000) three hundred fifty thousand (350,000) shares, which number shall be adjusted to reflect stock dividends, stock splits, reverse stock splits and similar matters occurring after February 5, 2019 the date of the 2026 annual Meeting that affect the number of outstanding shares of Common Stock.

c. The Trustee shall use amounts contributed pursuant to Sections 7(a) and 7(b) to purchase shares of the Common Stock of the Company on a monthly basis as promptly as practicable after receipt of such amounts. Common Stock may be purchased from sellers unaffiliated with the Company in private transactions, or such purchases may be effected on the New York Stock Exchange. No private transaction may be at a price greater than the then-market price of the Company's Common Stock on the New York Stock Exchange. Common Stock may not be purchased from the Company or its affiliates.

d. Following each stock purchase, the Trustee shall allocate shares purchased by the Trustee to the participants’ accounts pro rata according to their respective contributions to the purchase price. The cost per share charged against the account of each participant for shares allocated to the participant’s account shall be the average cost to the Trustee for the shares purchased by the Trustee (including brokerage fees and any other expenses directly applicable to the purchase of such shares). Both whole and fractional shares shall be allocated.

e. The Trustee shall cause a participant account to be maintained for each participant and shall issue stock certificates to a participant only upon the circumstances and in the manner provided in Section 10.

f.

Any shares of the Common Stock of the Company received by the Trustee as a stock dividend on shares held by it shall be treated as additional shares purchased by the Trustee under the Plan, at no cost, and shall be allocated and otherwise dealt with by the Trustee in the same manner as any other shares purchased by the Trustee under the Plan. Dividends received by the Trustee shall be deemed to have been received by the Trustee on the payment dates provided for the declaration of such dividends.

8. Voting of Stock Held Under the Plan: For each meeting of stockholders, the participants will have the right to vote all shares credited to their respective participant accounts under the Plan, whether registered in the name of the Trustee or its nominee. Shares held by the Trustee under the Plan but for any reason not allocated to the account of a participant will not be voted by the Trustee.

9. Costs of Administering the Plan: All costs and expenses of administering the Plan, including the fees of the Trustee, shall be paid by the Company.

10. Distributions from Participants’ Accounts:

a. A participant may from time to time elect to withdraw any number of whole shares allocated to the participant’s Plan account in any of the following ways, in each case by submitting an appropriate Plan Participation/Election Form and complying with such other conditions, if any, as may be required by the Trustee and/or the Company:

i. The participant may elect to have ownership of a number of whole shares withdrawn from the Plan and transferred from the participant’s Plan account to the participant as an individual. As promptly as practicable after the Trustee’s receipt of the withdrawal election, the Trustee will deduct the number of withdrawn shares from the participant’s Plan account and credit them to the participant’s individual share ownership account. Alternatively, the participant may direct the Trustee to have the withdrawn shares transferred to the participant’s brokerage account or to such other account or in such other manner as the Company may permit in its sole discretion.

ii. The participant may request the sale of a number of whole shares allocated to the participant’s Plan account. The Trustee will endeavor to sell the shares within one week of receiving written authorization to sell the shares and will promptly deliver a check to the participant less any commission charged by the Trustee.

b. The Trustee may establish such other procedures as it deems necessary to administer withdrawals in accordance with the intent of the Plan.

c. Except for sale commissions, no charges shall be imposed against the participant or the participant’s account by reason of a withdrawal of shares. However, if the participant requests the Trustee to issue and deliver a stock certificate for the withdrawn shares (in lieu of having them transferred to a share account), the participant will be responsible for any costs charged by the Trustee for the issuance of a paper certificate.

d. Except as set forth in Section 11, no participant shall have any right to receive a distribution of fractional shares in the participant’s account, or to receive the value thereof in cash.

e. A participant may designate one or more beneficiaries of Common Stock purchased pursuant to the Plan, upon the participant’s death, by completing a Transfer-On-Death (“TOD”) Beneficiary Designation Form provided by the Company and returned to and acknowledged by the Company prior to the participant’s death. At any time, the Company, in its sole discretion, may discontinue the allowance of TOD Beneficiary Designation Forms upon prior written or electronic notice to the participant. By executing the TOD Beneficiary Designation Form, the participant agrees on his/her/their behalf and on behalf of his/her/their heirs, executors, estate, beneficiaries, successors and assigns that: (i) the TOD Beneficiary Designation Form shall supersede all other documents and conflicting provisions (including without limitation those contained in any will, trust or other instrument) with respect to the shares purchased pursuant to the Plan, (ii) the Company is authorized to instruct or otherwise cause the applicable plan services administrator of the shares to transfer and/or issue the participant’s shares in accordance with the TOD Beneficiary Designation Form, (iii) the participant releases the Company and its affiliates and their respective employees, directors, officers, transfer agent, administrators, registered holder, trustees, representatives and advisors from all liability, and (iv) the participant hereby indemnifies such parties against any and all claims, liabilities and costs arising from or related to the TOD Beneficiary Designation Form and any such transfer and/ or issuance of the participant’s shares in accordance with such form. Any documents required by the Company to affect the transfer and/or issuance of the participant’s shares, including without limitation a death certificate, certification of trust, and/or required tax forms, shall be provided by a designated beneficiary, or the representative of a designated beneficiary, upon request prior to such transfer and/or issuance.

11. Termination of Participation in the Plan:

a. A participant may voluntarily elect to completely withdraw from the Plan and terminate participation in the Plan by submitting an appropriate Plan Participation/Election Form.

b. A participant’s participation in the Plan will automatically terminate upon the participant’s death, retirement, or other termination of employment.

c. Upon the termination of a participant’s Plan participation, the participant’s account will be settled and distributed as soon as practicable after such event occurs and after the Trustee receives notice of such termination or in the event of death, after the appointment of the legal representative of the estate of the deceased and/or the satisfaction of any other applicable legal requirements. The whole shares of stock which have been allocated to the account of such former participant shall be distributed as provided in section 10, and the Trustee shall pay to the former participant an amount in cash equal to any fractional share remaining in the former participant’s account, or in the case of the death of a participant who is the sole account holder, the Trustee shall make such distribution and payment to the designated beneficiary or beneficiaries of the account or, if none, to the legal representative of such participant.

12. Reports to Participants: The Trustee will render regular reports to each participant under the Plan, showing, for the period of the report, the contributions made and dividends, if any, credited to such participant's account; the number of shares allocated to such participant; the purchase price for such shares charged against the participant’s account; and the number of shares withdrawn, if any. Such reports shall be made not less frequently than once each quarter.

13. Amendment and Termination of the Plan: The Company reserves the right with respect to any or all employees, including those who may be participants under the Plan, to amend or terminate the Plan at any time; provided that, except with respect to termination of the Plan and changes in the amount of contributions by participants under Section 6 or by the Company or a division or subsidiary under Section 7(b), such authority may be delegated to any Senior Corporate Officer of the Company subject to such conditions as the Human Resources and Compensation Committee of the Company’s Board of Directors may determine from time to time. In the event of termination of the Plan, the Trustee as promptly as practicable after the date of termination shall deliver to the participant a certificate for the whole shares in the participant’s account, or transfer such whole shares to such brokerage account as the participant may have directed, and shall pay to the participant an amount in cash equal to any fractional share remaining in the participant’s account.

14. Section 16 Compliance: With respect to persons subject to Section 16 of the 1934 Act, transactions under the Plan are intended to comply with the applicable conditions of Rule 16b-3 or its successors under the 1934 Act. To the extent any provision of the Plan and any action thereunder fail to so comply, it shall be deemed null and void to the extent permitted by law.

15. Effective Date: The Plan became effective on October 15, 2003. This Amendment and Restatement incorporates all amendments through November 7, 2024 January 30, 2026.
