PROXY STATEMENT

March 26, 2026

GENERAL INFORMATION

Your Board of Directors (Board) is furnishing this proxy statement to you in connection with our solicitation of proxies to be used at our annual meeting of shareholders to be held on May 7, 2026. The proxy statement and other proxy materials are being sent to shareholders on March 26, 2026.

Registered Holders. If your shares are registered in your name, you may vote in person or by proxy. If you decide to vote by proxy, you may do so by telephone, over the Internet or by mail.

By telephone. After reading the proxy materials, you may call the toll-free number, 1-800-690-6903, using a touch-tone telephone. You will be prompted to enter your control number, which is a 16-digit number located in a box on your proxy card that you can also receive in the mail, if requested, then follow the simple instructions that will be given to you to record your vote.

Over the Internet. After reading the proxy materials, you may vote and submit your proxy online at www.proxyvote.com. Even if you request and receive a paper copy of the proxy materials, you may vote online by going to www.proxyvote.com and entering your control number, which is a 16-digit number located in a box on your proxy card that you can also receive in the mail, if requested, then follow the simple instructions that will be given to you to record your vote.

By mail. After reading the proxy materials, you may mark, sign and date your proxy card and return it in the enclosed prepaid and addressed envelope.

The Internet and telephone voting procedures have been set up for your convenience and have been designed to authenticate your identity, allow you to give voting instructions and confirm that those instructions have been recorded properly. Without affecting any vote previously taken, you may revoke your proxy by delivery to us of a new, later dated proxy with respect to the same shares, or giving written notice to us before or at the annual meeting. Your presence at the annual meeting will not, in and of itself, revoke your proxy.

Participants in the Materion Corporation Retirement Savings Plan. If you participate in the Retirement Savings Plan, the independent trustee for the plan, Fidelity Management Trust Company, will vote your plan shares according to your voting directions. You may give your voting directions to the plan trustee in any one of the three ways set forth above. If you do not return your proxy card or do not vote over the Internet or by telephone, the trustee will not vote your plan shares. Each participant who gives the trustee voting directions acts as a named fiduciary for the applicable plan under the provisions of the Employee Retirement Income Security Act of 1974, as amended.

Nominee Shares. If your shares are held by a bank, broker, trustee or some other nominee, that entity will give you separate voting instructions.

In addition to the solicitation of proxies by mail, we may solicit the return of proxies in person, by telephone, facsimile or e-mail. We will request brokerage houses, banks and other custodians, nominees and fiduciaries to forward soliciting material to the beneficial owners of shares and will reimburse them for their expenses. We will bear the cost of the solicitation of proxies.

Voting. At the close of business on March 12, 2026, the record date for the determination of shareholders entitled to notice of, and to vote at, the annual meeting, there were [20,814,258] shares of common stock outstanding and entitled to vote at the meeting. Each outstanding share of common stock entitles its holder to one vote on each matter brought before the meeting.

With respect to Proposal 1, the nominees receiving the greatest number of votes for their election will be elected as directors of Materion Corporation, subject to the Company's Majority Voting Policy (described below). The approval of each of Proposals 2 and 3 requires the affirmative vote of a majority of the votes cast, whether in person or by proxy, on such proposals at the annual meeting. The approval of Proposal 4 requires the affirmative vote of a majority of our outstanding shares of common stock.

Abstentions and Broker Non-votes. At the annual meeting, the inspectors of election appointed for the meeting will tabulate the results of shareholder voting. Under Ohio law and our Code of Regulations, properly signed proxies that are marked “abstain” or are held in “street name” by brokers and not voted on one or more of the items (but

otherwise voted on at least one item) before the meeting will be counted for purposes of determining whether a quorum has been achieved at the annual meeting.

If you do not provide directions to your broker, your broker or other nominee will not be able to vote your shares with respect to the election of directors (Proposal 1), the non-binding vote to approve named executive officer compensation (Proposal 3) or the approval of the amendment to the Amended and Restated Articles of Incorporation (Proposal 4).

Abstentions and broker non-votes will not affect the vote on the election of directors.

An abstention or broker non-vote with respect to the non-binding vote to approve named executive officer compensation (Proposal 3) will have no effect on the proposal as the abstention or broker non-vote will not be counted in determining the number of votes cast. An abstention or broker non-vote will have the effect of a vote against the approval of the amendment to the Amended and Restated Articles.

Because the vote to ratify the appointment of Ernst & Young LLP (Proposal 2) is considered to be routine, your broker or other nominee will be able to vote your shares with respect to this proposal without your instructions. An abstention will have no effect on this proposal as the abstention will not be counted in determining the number of votes cast.

* * *

We know of no other matters that will be presented at the meeting; however, if other matters do properly come before the meeting, the persons named in the proxy card will vote on these matters in accordance with their best judgment.

If you sign, date and return your proxy card but do not specify how you want to vote your shares, your shares will be voted as recommended by the Board as indicated on the proxy card.

BOARD OF DIRECTORS SKILL MATRIX

Our Board is comprised of members with varied experiences and backgrounds, which we believe enables thoughtful decision making. The skills matrix below provides an overview of the levels of experience that each of the nominees to our Board has in areas that impact our business. Each mark * indicates an experiential strength that was self-selected by each director.

Your Board of Directors unanimously recommends a vote for each of Thomas T. Edman, Vinod M. Khilnani, Emily M. Liggett, Robert J. Phillippy, Patrick Prevost, Craig S. Shular, Darlene J. S. Solomon, Ph.D., Robert B. Toth, and Jugal K. Vijayvargiya.

If any of these nominees becomes unavailable, it is intended that the proxies will be voted as the Board of Directors determines. We have no reason to believe that any of the nominees will be unavailable. The nominees receiving the greatest number of votes for their election will be elected as directors of Materion Corporation. However, our Board of Directors has adopted a Majority Voting Policy whereby, in an uncontested election, any nominee for director who receives a greater number of votes “withheld” from his or her election than votes “for” his or her election is expected to tender his or her resignation following certification of the shareholder vote, subject to a 90-day review process by our Nominating, Governance, and Corporate Responsibility Committee and Board of Directors to consider whether the tendered resignation should be accepted. An abstention or broker non-vote is not treated as a vote “withheld” under our Majority Voting Policy. For additional details on the Majority Voting Policy, see page 11 of this proxy statement.

We have adopted a Policy Statement on Significant Corporate Governance Issues and a Code of Conduct Policy in compliance with the New York Stock Exchange (NYSE) and Securities and Exchange Commission (SEC) requirements. These materials, along with the charters of the Audit and Risk, Compensation and Human Capital, and Nominating, Governance, and Corporate Responsibility Committees of our Board, which also comply with applicable requirements, are available on our website at https://materion.com, or upon request by any shareholder to: Secretary, Materion Corporation, 6070 Parkland Boulevard, Mayfield Heights, Ohio 44124. We also make our reports on Forms 10-K, 10-Q and 8-K available on our website, free of charge, as soon as reasonably practicable after these reports are filed with the SEC. Any amendments or waivers to our Code of Conduct Policy, Committee Charters and Policy Statement on Significant Corporate Governance Issues will also be made available on our website. The information on our website is not incorporated by reference into this proxy statement or any of our periodic reports.

Director Independence

The NYSE listing standards require that all listed companies have a majority of independent directors. For a director to be “independent” under the NYSE listing standards, the board of directors of a listed company must affirmatively determine that the director has no material relationship with the Company, or its subsidiaries or affiliates, either directly or as a partner, shareholder or officer of an organization that has a relationship with the Company, or its subsidiaries or affiliates. Our Board has adopted the following standards, which are identical to those of the NYSE listing standards, to assist in its determination of director independence. A director will be determined not to be independent under the following circumstances:

•the director is, or has been within the last three years, an employee of the Company, or an immediate family member is, or has been within the last three years, an executive officer of the Company;

•the director has received, or has an immediate family member who has received, during any 12-month period within the last three years, more than $120,000 in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service);

•the director (a) is a current partner or employee of a firm that is the Company’s internal or external auditor; (b) has an immediate family member who is a current partner of such a firm; (c) has an immediate family member who is a current employee of such a firm and personally works on the Company’s audit; or (d) was or has an immediate family member who was within the last three years a partner or employee of such a firm and personally worked on the Company’s audit within that time;

•the director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of the Company’s present executive officers at the same time serve or served on that company’s compensation committee; or

•the director is a current employee, or an immediate family member is a current executive officer, of a company that has made payments to, or received payments from, the Company for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1,000,000 or two percent of such other company’s consolidated gross revenues.

Additionally, for purposes of determining whether a director has a material relationship with the Company apart from his or her service as a director, our Board has deemed the following relationships as categorically immaterial:

•the director, or an immediate family member, is a current employee, director or trustee of a tax-exempt organization and the Company’s contributions to the organization (excluding Company matching of employee contributions) in any fiscal year are less than $120,000; or

•the director is a director of a company that has made payments to, or received payments or deposits from, the Company for property, goods or services in the ordinary course of business in an amount which, in any fiscal year, is less than the greater of $1,000,000, or two percent of such other company’s consolidated gross revenues.

Our Board has affirmatively determined that each of our current directors, other than Mr. Vijayvargiya, is “independent” within the meaning of that term as defined in the NYSE listing standards and a “non-employee director” within the meaning of that term as defined in Rule 16b-3(b)(3) promulgated under the Securities Exchange Act of 1934 (Exchange Act).

Charitable Contributions

Within the preceding three years, we have not made a contribution to any charitable organization in which any of our directors serves as a director, trustee, or executive officer.

Non-management Directors and Non-Executive Chairman

Our Policy Statement on Significant Corporate Governance Issues provides that the non-management members of the Board will meet during each regularly scheduled meeting of the Board of Directors in executive session. Additional executive sessions may be scheduled by the Non-Executive Chairman or other non-management directors. The Non-Executive Chairman will chair these sessions. Mr. Khilnani was appointed our Non-Executive Chairman in January 2018.

The non-management directors have access to our management as they deem necessary or appropriate. In addition, the Chair of each of the Audit and Risk Committee, Nominating, Governance, and Corporate Responsibility Committee and Compensation and Human Capital Committee meets periodically with members of senior management.

In addition to the other duties of a director under our Policy Statement on Significant Corporate Governance Issues, the Non-Executive Chairman, in collaboration with the other independent directors, is responsible for coordinating the activities of the independent directors and in that role will:

•chair the executive sessions of the independent directors at each regularly scheduled meeting;

•determine the timing and structuring of Board meetings;

•establish the agenda for Board meetings, including allocation of time as well as subject matter;

•determine the quality, quantity and timeliness of the flow of information from management to the Board;

•serve as the independent point of contact for shareholders wishing to communicate with the Board other than through management;

•interview all Board candidates and provide the Nominating, Governance, and Corporate Responsibility Committee with recommendations on each candidate;

•maintain close contact with the Chairman of each standing committee and assist in ensuring communications between each committee and the Board;

•lead the Chief Executive Officer annual evaluation process; and

•be the ombudsman for the Chief Executive Officer to provide two-way communication with the Board.

Board Communications

Shareholders or other interested parties may communicate with the Board as a whole, the non-executive chairman or the non-management directors as a group, by forwarding relevant information in writing to: Non-Executive Chairman, c/o Secretary, Materion Corporation, 6070 Parkland Boulevard, Mayfield Heights, Ohio 44124. Any other communication to individual directors or committees of the Board of Directors may be similarly addressed to the appropriate recipients, c/o Secretary, Materion Corporation, 6070 Parkland Boulevard, Mayfield Heights, Ohio 44124.

Board Leadership

The Board does not have a policy as to whether the role of Chief Executive Officer and Chairman of the Board should be separate or combined, or whether the Chairman should be a management or non-management director. Currently, the roles of Chairman of the Board and Chief Executive Officer are split, though in the past these roles have been combined. Mr. Khilnani was appointed Non-Executive Chairman of the Board effective January 2018, eliminating the need for a Lead Director. During 2025, Mr. Vijayvargiya was the only member of our Board who was not independent.

Unless the Chairman of the Board is an independent director, a Lead Director would be elected solely by the independent members of our Board of Directors. The Lead Director works with the Chairman of the Board and other Board members to provide strong, independent oversight of the Company’s management and affairs as described above under "Non-management Directors and Non-Executive Chairman".

Risk Oversight

Our Board oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, including strategic objectives, to improve long-term organizational performance and enhance shareholder value. A fundamental part of risk management is not only understanding the risks a company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for the Company. The involvement of the full Board in setting the Company’s business strategy is a key part of its assessment of management’s appetite for risk and also a determination of what constitutes an appropriate level of risk for the Company.

While the Board has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk management. In particular, the Audit and Risk Committee focuses on financial risk, including internal controls, and receives an annual risk assessment report from the Company’s internal auditors. The Audit and Risk Committee also focuses on risks relating to precious metal inventory, precious metal security and cybersecurity.

As part of its program of regular oversight, the Audit and Risk Committee is responsible for overseeing cyber risk, information security, and information technology risk, including management’s actions to identify, assess, mitigate, and remediate material cyber issues and risks. The Audit and Risk Committee receives at least quarterly reports from the Chief Information Officer on the Company’s information technology and cyber risk profile, enterprise cyber program, key enterprise cyber initiatives, and significant updates on external audits of our information security program. In 2025, the full Board attended one of the Audit and Risk Committee meetings at which information technology and cyber risk were discussed. Additionally, at least annually, the full Board attends a cybersecurity

training session from external experts and reviews and discusses the Company’s technology strategy with the Chief Information Officer and approves the Company’s technology strategic plan.

In addition, management provides a risk management report, including a financial risk assessment and enterprise risk management update and information technology contingency plan, to the Audit and Risk Committee. In setting compensation, the Compensation and Human Capital Committee strives to create incentives that encourage a level of risk-taking consistent with the Company’s business strategy. Finally, the Company’s Nominating, Governance, and Corporate Responsibility Committee conducts an annual assessment of the Board in accordance with corporate governance and risk management best practices and additionally oversees the Company's risk with respect to climate change. The Company believes that the Board’s role in risk oversight is consistent with the Company’s leadership structure, with management having day-to-day responsibility for assessing and managing the Company’s risk exposure and the Board and its committees providing oversight in connection with those efforts, with particular focus on the most significant risks facing the Company.

Audit and Risk Committee

The Audit and Risk Committee held six meetings in 2025. The full Board attended two of the six Committee meetings in 2025. The Committee membership consists of Mr. Phillippy, as Chairman, Ms. Liggett, Mr. Toth, Mr. Edman and Dr. Reddy. Under the Committee charter, the Committee’s principal functions include assisting our Board in fulfilling its oversight responsibilities with respect to:

•the integrity of our financial statements and our financial reporting process;

•compliance with ethics policies and legal and other regulatory requirements;

•our independent registered public accounting firm’s qualifications and independence;

•our systems of internal accounting and financial controls;

•the performance of our independent registered public accounting firm and of our internal audit functions;

•assisting the Board in fulfilling its oversight responsibilities with respect to financial risk, including internal controls, as well as risks relating to precious metal security and cybersecurity; and

•other matters as deemed appropriate, including our Code of Conduct Policy and our risk management practices and policies.

No member of the Committee serves on the audit committee of three or more public companies in addition to ours unless the Board determines that such services would not impair the member's ability to serve on the Committee. The Committee also prepared the Committee report included under the heading “Audit Committee Report” in this proxy statement.

Audit and Risk Committee Expert, Financial Literacy and Independence

Our Board has determined that Messrs. Phillippy, Toth and Edman and Ms. Liggett are "audit committee" financial experts, as defined by the SEC. Each member of the Audit and Risk Committee is financially literate and satisfies the independence requirements as set forth in the NYSE listing standards.

Compensation and Human Capital Committee

The Compensation and Human Capital Committee held five meetings in 2025. The Committee membership consists of Mr. Shular, as Chairman, Dr. Solomon, and Messrs. Khilnani and Prevost. Each member of the Committee has been determined by the Board to be independent in accordance with NYSE listing standards. The Committee may, at its discretion, delegate all or a portion of its duties and responsibilities to a subcommittee, provided that such subcommittee has a published charter in accordance with NYSE rules. The Committee’s principal functions include:

•reviewing and approving executive compensation, including severance payments;

•overseeing and recommending equity and non-equity incentive plans;

•overseeing regulatory compliance with respect to compensation matters;

•advising on senior management compensation; and

•reviewing and discussing the Compensation Discussion and Analysis (CD&A) and Compensation Committee Report.

For additional information regarding the operation of the Committee, see the “Compensation Discussion and Analysis” in this proxy statement.

Nominating, Governance, and Corporate Responsibility Committee

The Nominating, Governance, and Corporate Responsibility Committee held five meetings in 2025. The Committee membership consists of Mr. Khilnani, as Chairman, Ms. Liggett, Messrs. Edman, Phillippy, Prevost, Shular, and Toth

and Drs. Reddy and Solomon. All of the members are independent in accordance with the NYSE listing requirements. The Committee’s principal functions include:

•evaluating candidates for Board membership, including any nominations of qualified candidates submitted in writing by shareholders to our Secretary;

•making recommendations to the full Board regarding director compensation;

•making recommendations to the full Board regarding governance matters;

•overseeing Company strategies regarding key environmental (including the impact of climate change), health and safety, sustainability and social responsibility matters;

•overseeing the evaluation of the Board and management of the Company;

•evaluating potential successors to the Chief Executive Officer for recommendation to the Board and assisting in management succession planning; and

•reviewing related party transactions.

As noted above, the Committee is involved in determining compensation for our directors. The Committee administers our equity incentive plans with respect to our directors, including approval of grants of stock options and other equity or equity-based awards, and makes recommendations to the Board with respect to incentive compensation plans and equity-based plans for directors. The Committee periodically reviews director compensation in relation to comparable companies and other relevant factors. Any change in director compensation must be approved by the Board. No executive officer other than the Chief Executive Officer in his capacity as director participates in setting director compensation. From time to time, the Committee or the Board may engage the services of a compensation consultant to provide information regarding director compensation at comparable companies.

Annual Board Self-assessments

The Board has instituted annual self-assessments of the Board, as well as of the Audit and Risk Committee, the Compensation and Human Capital Committee and the Nominating, Governance, and Corporate Responsibility Committee, to assist in determining whether the Board and its committees are functioning effectively. Annually, each of the members of the Board completes a detailed survey regarding the Board and its committees that provides for quantitative ratings in key areas and seeks subjective comments. The results of the survey are compiled and discussed at the Board level and in each committee. Any matters requiring follow-up are identified by the Nominating, Governance, and Corporate Responsibility Committee, which is responsible for any action items. Each of the committees also reviews its charter on an annual basis for any changes.

Nomination of Director Candidates

The Nominating, Governance, and Corporate Responsibility Committee will consider candidates recommended by shareholders for nomination as directors of Materion Corporation. Any shareholder desiring to submit a candidate for consideration by the Committee should send the name of the proposed candidate, together with biographical data and background information concerning the candidate, to the Nominating, Governance, and Corporate Responsibility Committee, c/o Secretary, Materion Corporation, 6070 Parkland Boulevard, Mayfield Heights, Ohio 44124.

In recommending candidates to the Board for nomination as directors, the Committee’s charter requires it to consider such factors as it deems appropriate, consistent with our Policy Statement on Significant Corporate Governance Issues. These factors are as follows:

•broad-based business, governmental, non-profit, or professional skills and experiences that indicate whether the candidate will be able to make a significant and immediate contribution to the Board’s discussion and decision-making in the array of complex issues facing the Company;

•exhibited behavior that indicates he or she is committed to the highest ethical standards and the values of the Company;

•special skills, expertise and background that add to and complement the range of skills, expertise and background of the existing directors;

•whether the candidate will effectively, consistently and appropriately take into account and balance the legitimate interests and concerns of all our shareholders and other stakeholders in reaching decisions;

•a global business and social perspective, personal integrity and sound judgment; and

•time available to devote to Board activities and to enhance their knowledge of the Company.

As part of the analysis of the foregoing factors, the Committee considers whether the candidate enhances the diversity of the Board. Such diversity includes professional background and capabilities, knowledge of specific

industries and geographic experience, as well as the more traditional diversity concepts of race, gender and national origin.

The Committee’s evaluation of candidates recommended by shareholders does not differ materially from its evaluation of candidates recommended from other sources.

The Committee utilizes a variety of methods for identifying and evaluating director candidates. The Committee regularly reviews the appropriate size of the Board and whether any vacancies on the Board are expected due to retirement or otherwise. In the event that vacancies are anticipated, or otherwise arise, the Committee considers various potential candidates for director. Candidates may come to the attention of the Committee through current Board members, professional search firms, shareholders or other persons. Additionally, from time to time, the Committee has used the services of an executive search firm to help identify potential director candidates who possess the characteristics described above. In such instance, the search firm has prepared a biography of each candidate, conducted reference checks and screened candidates.

A shareholder of record entitled to vote in an election of directors who timely complies with the procedures set forth in our code of regulations and with all applicable requirements of the Exchange Act and the rules and regulations thereunder, may also directly nominate individuals for election as directors at a shareholders’ meeting. Copies of our code of regulations are available by a request addressed to Materion Corporation, c/o Secretary, 6070 Parkland Boulevard, Mayfield Heights, Ohio 44124.

To be timely, notice of a shareholder nomination for an annual meeting must be received at our principal executive offices not fewer than 60 nor more than 90 days prior to the date of the annual meeting. However, if the date of the meeting is more than one week before or after the first anniversary of the previous year’s meeting and we do not give notice of the meeting at least 75 days in advance, nominations must be received within ten days from the date of our notice.

Majority Voting Policy

Our Board adopted a Majority Voting Policy whereby, in an uncontested election, any nominee for director who receives a greater number of votes “withheld” from his or her election than votes “for” election, which we refer to as a Majority Withheld Vote, is expected to tender his or her resignation following certification of the shareholder vote. In such an event, the Nominating, Governance, and Corporate Responsibility Committee will consider the tendered resignation and make a recommendation to the Board. The Board will act on the Committee’s recommendation within 90 days following certification of the shareholder vote. Any director who tenders his or her resignation pursuant to this policy will not participate in the Committee’s recommendation or Board’s action regarding whether to accept or reject the tendered resignation.

However, if each member of the Committee received a Majority Withheld Vote in the same election, then the Board would appoint a committee comprised solely of independent directors who did not receive a Majority Withheld Vote at that election to consider each tendered resignation offer and recommend to the Board of Directors whether to accept or reject each resignation. Further, if all of the director nominees received a Majority Withheld Vote in the same election, the Board would appoint a committee comprised solely of independent directors to consider each tendered resignation offer and recommend to the Board of Directors whether to accept or reject each resignation.

Director Attendance

Our Board held five meetings in 2025. All of the current directors who were directors in 2025 attended at least 75% of the Board and assigned committee meetings during the period each individual served as a director during 2025. Our policy is that directors are expected to attend all meetings, including the annual meeting of shareholders. All of our directors attended last year’s annual meeting of shareholders.

Corporate Responsibility

For more than 90 years, Materion has helped our customers meet their greatest science and technology challenges. Our ability to deliver on our mission is rooted, in part, in our strong corporate responsibility practices towards our customers, our employees, and our operations and communities. We are committed to ensuring that our organization’s governance and operations are fully aligned with environmentally and socially responsible practices. Our corporate responsibility is structured around three focus areas:

Our Commitment - From our leadership team to the Board of Directors, strong governance, ethical operations and upholding compliance standards are vital to our organization's continued advancement.

Our People – Materion’s values and corporate culture define who we are, how we act, and what we believe is our responsibility to conducting business. And our diverse employee base, that embodies our culture, is the driving force behind our success.

Our Operations and Communities – Materion consistently strives to integrate a variety of sustainability-based initiatives in our own operations and in the communities where we operate, from more efficient use of energy and materials to educating our employees on how to better serve as stewards of the planet. We also require our business partners and suppliers to abide by the same responsible business standards and principles.

In 2025, our oversight and implementation of our corporate responsibility practices benefited from the following:

•Oversight by the Nominating, Governance and Corporate Responsibility (NGCR) Committee: In 2025, in addition to corporate governance, our NGCR Committee continued to exercise its oversight of environmental, sustainability and social responsibility matters significant to the Company. The NGCR Committee oversees and periodically reviews the Company’s strategies regarding key environmental (including climate change), health and safety, sustainability and social responsibility matters. NGCR Committee membership currently includes all of our independent directors, ensuring an integrated and aligned oversight approach to corporate responsibility. The NGCR Committee held five meetings in 2025 and the Company’s environmental and social responsibility initiatives and related matters, including but not limited to, matters relating to climate change, were discussed at three of those meetings.

•Executive oversight: Executive oversight of environmental and social matters is conducted by management through our steering committee, which is composed of leaders from multiple functions including operations, legal, human resources, finance, and purchasing. In addition, environmental and social matters are integrated into our risk oversight and enterprise-wide risk management approach. In support of these broad-based efforts, in 2021 Materion appointed a dedicated leadership position to support ongoing and new environmental and social responsibility activities and strategic initiatives globally, including, but not limited to, matters relating to climate change. This manager also supports identification and deployment of best-in-class sustainability-focused operational programs, systems and processes across Materion operations globally.

•Diversity & Inclusion: We have an employee Diversity & Inclusion Council, established in 2020, that continues to oversee the progression of various initiatives in support of improving the maturity of our enterprise-wide inclusion practices. Some of these initiatives include the continued operation of Employee Resource Groups, supporting inclusive hiring practices, and the establishment of baseline metrics against which we measure ourselves.

Good corporate citizenship and our commitment to strong environmental and social responsibility practices for our people, our operations and our communities are important elements of our vision, mission and values at Materion. We conduct our business activities in accordance with these values. Additionally, the core of our business ethics is “doing the right thing.” This fundamental principle is what drives Materion to be a socially responsible business that meets the highest standards of ethics and professionalism. We strive to:

• Maintain the highest standards of health, safety and security;

• Produce materials that enable technologies to provide a safer and more sustainable environment;

• Design, manufacture and distribute products in a safe and environmentally responsible manner;

• Respect and protect human rights wherever we operate;

• Embrace a set of values where we partner in the betterment of our communities; and

•Promote fair dealing and respect towards our customers, shareholders, employees, business partners and communities.

RELATED PARTY TRANSACTIONS

We recognize that transactions between any of our directors or executive officers and us can present potential or actual conflicts of interest and create the appearance that our decisions are based on considerations other than the best interests of our shareholders. Pursuant to its charter, the Nominating, Governance, and Corporate Responsibility Committee considers and makes recommendations to the Board with regard to possible conflicts of interest of Board members or management. The Board then makes a determination as to whether to approve the transaction.

The Committee reviews all relationships and transactions in which Materion Corporation and its directors and executive officers or their immediate family members are participants to determine whether such persons have a direct or indirect material interest. Our Secretary is primarily responsible for the development and implementation of processes and controls to obtain information from the directors and executive officers with respect to related person transactions in order to enable the Committee to determine, based on the facts and circumstances, whether Materion or a related person has a direct or indirect material interest in the transaction. As set forth in the Committee’s charter, in the course of the review of a potentially material related person transaction, the Committee considers:

•the nature of the related person’s interest in the transaction;

•the material terms of the transaction, including, without limitation, the amount and type of transaction;

•the importance of the transaction to the related person;

•the importance of the transaction to Materion;

•whether the transaction would impair the judgment of a director or executive officer to act in the best interest of Materion; and

•any other matters the Committee deems appropriate.

Based on this review, the Committee will determine whether to approve or ratify any transaction which is directly or indirectly material to Materion or a related person.

Any member of the Committee who is a related person with respect to a transaction under review may not participate in the deliberations or vote on the approval or ratification of the transaction; however, such director may be counted in determining the presence of a quorum at a meeting of the Committee that considers the transaction. There were no related party transactions in 2025.

AUDIT COMMITTEE REPORT

The Audit and Risk Committee oversees 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 systems of internal controls. In fulfilling its oversight responsibilities, the Audit and Risk Committee reviewed the audited financial statements in the annual report with management, and discussed with management the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments and the clarity of disclosures in the financial statements.

The Audit and Risk Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and the SEC. The Audit and Risk Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm’s communications with the Audit and Risk Committee concerning independence, and has discussed with the independent registered public accounting firm such firm’s independence.

The Audit and Risk Committee discussed with the Company’s internal auditors and the independent registered public accounting firm the overall scope and plans for the respective audits. The Audit and Risk Committee meets with the internal auditors and the independent registered public accounting firm, with and without management present, to discuss the results of their examinations, their evaluations of the Company’s internal controls, and the overall quality of the Company’s financial reporting. The Audit and Risk Committee held six meetings during 2025.

In reliance on these reviews and discussions, the Audit and Risk Committee recommended to the Board of Directors (and the Board has approved) that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2025 for filing with the SEC.

The current Audit and Risk Committee charter is available on our website at https://materion.com.

EXECUTIVE COMPENSATION

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis (CD&A) provides an overview of our executive compensation program and 2025 pay determinations for our named executive officers (NEOs), as shown below:

Named Executive Officers

Jugal K. Vijayvargiya, President and Chief Executive Officer

Shelly M. Chadwick, Vice President, Finance and Chief Financial Officer

Gregory R. Chemnitz, Vice President, General Counsel and Secretary

This CD&A consists of the following three sections:

Section I: Executive Summary - 2025 in Review

Section II: Executive Compensation Program Overview

Section III: Details and Analysis of the 2025 Executive Compensation Program

Section I: Executive Summary - 2025 in Review

Materion Corporation has a long-standing and strong commitment toward pay-for-performance in its executive compensation program. We maintain this orientation throughout economic cycles that may cause fluctuation in our operating results.

We believe the decisions regarding our NEO compensation program in 2025 described in the CD&A below reflect our ongoing commitment to sustaining our pay-for-performance philosophy.

Company Overview

Materion Corporation is a global leader in advanced materials solutions, serving high-performance, rapidly expanding industries including semiconductor, space, energy and defense. With nearly 100 years of deep technical expertise in specialty engineered alloy systems, Materion partners with customers worldwide to develop innovative materials that enable critical technologies and move the world forward. Headquartered in Mayfield Heights, Ohio, the company employs approximately 3,000 people and serves customers in more than 60 countries.

Over the past decade, Materion has undergone a multi-phase transformation, evolving from a traditional metals and mining company rooted in our beryllium heritage into a leading supplier of advanced materials that address a broad range of complex technical challenges. Through strategic initiatives focused on new product development, portfolio and footprint optimization, operational excellence, and complementary bolt-on acquisitions, we have built a diversified portfolio of specialty products that serve attractive end markets experiencing exciting secular growth trends, while delivering a step change in profitability. This deliberate evolution has strengthened the company, enhanced our market position and set a solid foundation for continued long-term success.

Current macroeconomic trends have created exciting opportunities that align well with our product portfolio and capabilities. The proliferation of AI is driving rapid growth across several of our end markets and product lines. The build out of datacenters is creating strong demand for our advanced sputtering targets, essential to next-generation chips and data storage. AI is also creating a step change in the demand outlook for Energy requirements, and our products are critical in new and emerging energy solutions. The growing commercial space market is also impacted as satellite launches continue to increase to support connectivity, and our full material set supports these applications.

Additionally, increased defense spending by the U.S. and allied countries is creating significant new opportunities and stronger demand. These secular growth trends are driving strong demand for our advanced materials across multiple high-value markets.

As Materion enters a new phase of strong organic growth, we remain committed to executing key initiatives designed to drive operational excellence, expand global manufacturing capabilities, and capture high-value market opportunities. With a strong foundation and clear strategic focus, Materion is well-positioned to continue delivering long-term value to our customers, employees, and shareholders.

Below is an overview of business segments and end markets in 2025.

Internally, the Company manages the business based on value-added sales, which is a non-GAAP financial measure that removes the impact of pass-through metal costs and allows for analysis without the distortion of the movement or volatility in metal prices and changes in mix due to customer-supplied material. A reconciliation of net sales, the most directly comparable GAAP financial measure, to value-added sales is included herein in Appendix B.

2025 Performance at a Glance

2025 was another year of strong performance in challenging markets by managing the business with a focus on what the Company can control through operational excellence and cost management.

A reconciliation of adjusted EBITDA to EBITDA and net income is included herein in Appendix B.

Summary NEO Compensation Decisions and Actions in 2025


Factors Guiding NEO Compensation Decisions						Market compensation rates, including Materion's compensation peer group, for each position
						Company's performance against pre-established goals
						Experience, skills, expected future contributions, and leadership
						Contributions and performance of each individual
2025 NEO Compensation Decisions (see below for details)						Target Total Direct Compensation: The target total direct compensations for Ms. Chadwick and Messrs. Vijayvargiya, and Chemnitz in 2025 were managed within 20% of the market median.
						Base Pay: NEO salary increases were 3.1% for Mr. Vijayvargiya, 4.0% for Ms. Chadwick and 4.0% for Mr. Chemnitz.
						Annual Incentive Plan (AIP): Payout under the AIP was based on Company adjusted EBIT, value-added sales growth, and simplified free cash flow performance versus goals. The Company achieved 0.0% funding for its adjusted EBIT component, 0.0% funding for its value-added sales growth component and 0.0% funding for its simplified free cash flow component, resulting in AIP awards at 0.0% of target for our NEOs.
						Long-term Incentives (LTI): The Committee determined 2025 equity grants after carefully considering (1) the Company's 2024 performance, (2) comparative market pay practices and (3) our performance-driven compensation philosophy. In 2025, shareholder value creation is achieved through performance-based grants representing approximately 75% of the overall target equity opportunities for Mr. Vijayvargiya, and 60% of the overall target equity opportunities for Ms. Chadwick and Mr. Chemnitz.
Shareholder Advisory Vote Consideration						At our 2025 annual meeting of shareholders, we received over 95% approval from our shareholders, based on the total votes counted, for our annual advisory "Say-on-Pay" proposal to approve the compensation of our NEOs. The Committee considered these voting results at its meetings after the vote, and while it believes the voting results demonstrate significant support for our overall executive compensation program, the Committee remains dedicated to continuously improving the existing executive compensation program and the governance environment surrounding the overall program. The Committee did not make any changes to its compensation policies and practices that were specifically driven by the results of the Say-on-Pay vote.

Changes in Prior Years

The Committee has made a number of other executive pay and related corporate governance changes to further align our executive compensation program with market competitive best practices. Specifically, the Committee:


Compensation Program Design						Established stock ownership and retention guidelines for the NEOs and non-employee directors to further promote long-term equity ownership, and in 2022 discontinued the recognition of unexercised vested and unvested SARs as stock ownership. In 2025, we increased the required stock ownership for the CEO and non-employee directors to six times salary from five.
						Put more stock and compensation at risk by increasing the weighting of the Performance Restricted Stock Units (PRSUs) to, typically, between 40% and 50% of the total target LTI award mix for our NEOs. The LTI program for 2025 had four components, including stock appreciation rights (SARs), PRSUs tied to our Relative Total Shareholder Return (RTSR) (RTSR PRSUs), PRSUs tied to our absolute Return On Invested Capital (ROIC) (ROIC PRSUs) and time-based RSUs. Including all PRSUs and SARs, typically 60% to 75% of the total target LTI award mix for our NEOs is “at risk”.
						Effective December 31, 2019, the Materion Corporation Pension Plan (the Pension Plan) was amended, freezing the accrued benefit for all participants. Beginning January 1, 2020, the Materion Corporation Retirement Savings Plan (401(k) Plan) was enhanced, providing participants with a Company matching contribution of $1.00 for each dollar they elect to contribute up to the first 4% of compensation deferred. The Company match is subject to the applicable annual Internal Revenue Code (Code) limitation.
						In conjunction with freezing the Pension Plan, the Materion Corporation Supplemental Retirement Benefit Plan (SRBP) was amended, freezing the accrued benefit for all participants, effective December 31, 2019.
Corporate Governance						Implemented a "double trigger" change in control vesting provision for all equity grants, which provides that outstanding equity grants will vest on an accelerated basis either if the awards are not continued, assumed or replaced upon the occurrence of a change in control or if the executive experiences a subsequent qualifying termination of employment. A change of control is triggered if any Person’s beneficial ownership reaches or exceeds 30%.
						Maintain and operate a Compensation Clawback Policy to comply with both certain new clawback listing standards of the New York Stock Exchange and new rules and regulations promulgated by the U.S. Securities and Exchange Commission. In connection with the adoption of the new Compensation Clawback Policy, the Board amended and revised in its entirety the company’s predecessor 2011 Clawback Policy, as amended and restated, in the form of the Supplemental Clawback Policy. The Supplemental Clawback Policy operates, effective October 2, 2023, separate and distinct from (but in addition to) the new Compensation Clawback Policy, applying in particular with respect to any compensation that is not covered by or subject to the new policy by its terms.

Section II: Executive Compensation Program Overview

Compensation Philosophy and Objectives

Our long-standing compensation philosophy is guided by three key objectives:

•Attract, motivate and help retain key executives with the ability to profitably grow our business portfolio;

•Build a pay-for-performance environment with total pay levels targeted at the competitive market median; and

•Provide opportunities for share ownership to align the interests of our executives with our shareholders.

We meet these objectives through careful alignment of the elements of executive compensation with the interests of shareholders. For example, approximately 84% of CEO compensation and 69% of other NEO executive compensation is at-risk. It is this alignment of compensation goals that has been instrumental in Materion’s growth path. Below is more detail on these compensation components and our pay philosophy.

Primary Components of the NEO Compensation Program for 2025

To achieve these objectives, our NEO compensation program includes the following primary components:

Component

Purpose / Objective

Key Characteristics

Base Salaries

Provide a fixed, competitive level of pay based on responsibility, qualifications, experience and performance

Fixed cash compensation

Annual Incentive Plan (AIP)

Align variable pay with short-term performance in support of our annual business plan and strategic objectives

Variable cash incentive compensation earned at 0% – 200% based on Company performance over a 1-year performance period

Long-term Incentives (LTI)

PRSUs

Aligns NEOs' interests with those of our shareholders by motivating and rewarding achievement of long-term shareholder value and growth; promotes retention

Variable stock-based incentive compensation earned at 0% – 200% based on Company performance over a 3-year performance period; value dependent upon achievement of performance metrics and our stock price performance relative to our peer group

Stock Appreciation Rights (SARs)

Aligns NEOs' interests with those of our shareholders by rewarding achievement of upside potential; promotes retention

Stock-based incentive compensation that generally vests in 3 equal annual installments; only provides value if our stock price appreciates

RSUs

Aligns NEOs' interests with those of our shareholders by rewarding long-term value creation; promotes retention

Stock-based incentive compensation that generally vests in 3 equal annual installments; value tied to our stock price

Health, Welfare and Retirement Benefits

Provide competitive health, welfare and retirement benefits and enhance executive retention. NEOs are also eligible for periodic executive physicals, but no other perquisites are provided

Retirement benefits are payable in cash following qualifying separation from service

Target Total Pay Mix

Due to our pay-for-performance philosophy, the Committee has set base salaries as a relatively small part of target total compensation for the NEOs and has provided a significant portion of target total compensation in the form of equity-based LTI, consisting of grants of SARs, PRSUs and RSUs that align NEOs' interests with those of our shareholders. In 2025, performance-based LTI grants represented approximately 75% of the total target equity opportunity offered to Mr. Vijayvargiya and approximately 60% for Ms. Chadwick and Mr. Chemnitz. We view SARs as inherently performance-based because they will only have value to the extent our stock price appreciates.

The following charts summarize the target total compensation mix for our CEO and the average target total compensation mix for our other NEOs:

Our Commitment to Sound Corporate Governance

The Committee works to ensure that our executive compensation program adheres to sound corporate governance and market competitive best practices. The following table highlights our corporate governance practices:


			What We DO						What We DON'T DO
			Target pay mix places primary emphasis on variable incentives to align compensation with performance.						No single trigger acceleration provisions in the event of a change in control for cash severance or equity awards.
			Incentives are tied to pre-established, objective goals, with no payouts for below-threshold performance.						No excessive benefits and no NEO perquisites, other than periodic executive physicals.
			Majority of LTI awards are “at risk”, typically with 40% to 50% comprised of PRSUs tied to three-year performance goals.						No excise or other tax gross-ups in current or future NEO employment or severance agreements.
			NEOs are subject to mandatory stock ownership guidelines along with stock holding requirements.						No repricing of SARs without prior shareholder approval.
			Incentive awards to NEOs are subject to formal clawback policies.						No multi-year guarantees for salary increases, bonuses, incentives, or equity grants.
			NEO compensation is initially targeted in the median range of our peer group and third-party general industry surveys for all elements of compensation, including base salary, target MIP opportunities and target LTI awards.						No dividend equivalents or dividends paid on unearned PRSUs.
			Long term incentive plan uses both absolute and relative metrics						No share hedging or pledging activities.
			On an annual basis: i.We participate in executive compensation training via a 3rd party in order to keep current of compensation developments, shareholder's requirements, SEC reporting, etc. ii.Perform a review of our outside compensation advisor's performance and vote on their appointment.

The Compensation and Human Capital Committee and its Role in Determining NEO Compensation

The Committee is responsible for the design and oversight of our executive compensation programs covering NEOs, including the CEO. All of the members of the Committee are independent, non-employee directors as defined by the rules of the NYSE. The Committee makes policy and strategic recommendations to the Board of Directors (Board) and has authority delegated from the Board to, among other things:

•Implement executive compensation decisions;

•Design the base compensation, incentive compensation and benefit programs for the NEOs;

•Assess and address any inherent risks in executive and employee compensation programs;

•Oversee the equity incentive plans; and

•Oversee the administration of our stock ownership guidelines.

The Committee met five times in 2025 and all meetings included an executive session during which management was not present. In addition, the Committee acted by written consent twice. Most compensation decisions are finalized in the first quarter of each fiscal year. The Committee charter, which sets forth the Committee's responsibilities on a more comprehensive basis, is available under the “Corporate Governance” tab at http://materion.com and is reviewed on an annual basis to ensure it continues to satisfy changing corporate governance requirements and expectations.

The Role of the Independent Compensation Consultant

The Committee relies on an independent compensation consultant, Frederic W. Cook & Co., Inc. (FW Cook), as its independent compensation consultant. FW Cook assists in gathering and analyzing market data, advising the Committee on compensation standards and trends, and assisting in the implementation of policies and programs. FW Cook works with

the Chief Executive Officer and the executive(s) responsible for Human Resources to provide such assistance to the Committee. FW Cook does not provide any other services to the Company. The Committee annually reviews the independence status of its advisors and determined that FW Cook has no conflicts of interest in its role as compensation consultant to the Committee. The Committee has sole authority to determine the compensation for and to terminate FW Cook’s services.

The Role of the Compensation and Human Capital Committee in Reviewing Talent Development and Retention

Talent development is a key imperative of the company and gets substantial focus from the Committee and the executive leadership team. The Company provides employees with wide-ranging development programs, opportunities, and paths to success, which empower them to realize their full potential. For example, Apprenticeship programs have been implemented globally at several large plant sites. In addition, other talent development programs include career ladders which provide structured growth opportunities and career development assignments for professional employees.

In addition to Talent Development programs, on an annual basis, the Committee, along with the full Board of Directors, review company pay practices, succession plans, and People and Culture initiatives of the company. These programs are vital to helping ensure that top talent is hired, nurtured and retained by the Company. Each of the NEOs, along with the core executive management team play an important role in the development of the Company’s talent pipeline.

The Role of Management in Providing Input on Executive Compensation to the Committee

Management provides periodic updates to the Committee regarding business performance and forecasts. Management also provides input on incentive compensation plan performance goals, based on the annual business plan approved by the Board. As noted above, the CEO provides base salary recommendations for his direct reports whose compensation is subject to Committee oversight.

How Compensation is Set: Peer Group Companies

For 2025, compensation determinations and assessments were made primarily against a comparison group of 21 public companies in related industries as selected by FW Cook and reviewed and approved by the Committee.

FW Cook reviews and updates the comparison group for continued suitability based on industry, company size, and transactional activity among the peers.. The Committee reviewed the peer group used to evaluate 2025 pay and made no changes. The Committee has chosen companies that are size appropriate and align with the strategic business transformation that Materion has been undertaking to an Advanced Materials Company with technology driven products and solutions that deliver strong profit margins. The comparison group is the same peer group intended for determining long-term incentive RTSR PRSU award compensation for awards granted in 2025.


Advanced Energy Industries, Inc.			Knowles Corporation
Balchem Corporation			Methode Electronics Inc.
Carpenter Technology Corp.			Minerals Technologies Inc.
CTS Corporation			OSI Systems, Inc.
Hexcel Corporation			Quaker Chemical Corporation
Element Solutions Inc.			Rogers Corporation
Fabrinet			Sensient Technologies
Ingevity Corporation			Penguin Solutions
Innospec Inc.			Standex International Corp.
Kennametal Inc.			Stepan Company
			Viavi Solutions

We also rely on general industry third-party survey data when setting the terms of our compensation program. Survey data is size adjusted to reflect companies of similar size and scope. Survey information helps to confirm the validity and provide broader context to the peer group data, as well as provide data for positions where peer group data is not available from public filings with the SEC.

The median peer group data and the size-adjusted third-party survey data is used to set a targeted market median range for each compensation element. In making compensation decisions, the Committee generally targets individual NEO’s competitive positioning within the median range although . positioning may vary above or below the market median range due to the executive’s skills, experience in current role, tenure with the Company and individual performance.

Section III: Details and Analysis of the 2025 Executive Compensation Program

The following is an explanation and analysis of the 2025 compensation elements:

Base Salary

The Committee approved salary increases effective August 1, 2025, to improve the alignment with the competitive market and recognize past performance and future expected contributions.


	2024 Base Salary	2025 Base Salary	% Increase
Jugal K. Vijayvargiya	$970,000	$1,000,000	3.1%
Shelly M. Chadwick	512,000	532,500	4.0%
Gregory R. Chemnitz	486,400	505,900	4.0%

2025 Annual Incentive Plan (AIP)

Early in the year, the Board approved an annual operating plan that reflected our expectations for company performance during 2025. The annual operating plan called for a $4.4 million decrease in adjusted EBIT, a 1.2% decrease in value-added sales (VAS) growth and a target of simplified free cash flow (SFCF) to generate meaningful positive SFCF while also allowing for investment and working capital growth to support the growing business.

The Committee used the 2025 annual operating plan as the basis for 2025 AIP goals of adjusted EBIT, VAS growth, and SFCF. VAS growth is the amount equal to the Company’s sales minus the aggregate cost to the Company of the precious metals such as, gold, silver, platinum, palladium, copper, ruthenium, iridium, rhodium, rhenium, and osmium. SFCF is the amount equal to adjusted EBIT plus depreciation and amortization minus the change in working capital (accounts receivable, accounts payable and inventory) and capital investments. The adjusted EBIT, VAS growth, and SFCF goals accounted for 70%, 15%, and 15%, respectively, of each participating NEO's total target annual incentive opportunity.

The 2025 target annual incentive, as a percentage of base salary, for each participating NEO remained the same as 2022 for Mr.Vijayvargiya, 110%, Ms. Chadwick, 70% and Mr. Chemnitz, 56%.


Name	2025 AIP Performance Measures and Target Payout as a % of Salary
	Adjusted EBIT (70%)	VAS Growth (15%)	SFCF (15%)	Total AIP Target
Jugal K. Vijayvargiya	77.0%	16.5%	16.5%	110%
Shelly M. Chadwick	49.0%	10.5%	10.5%	70%
Gregory R. Chemnitz	39.2%	8.4%	8.4%	56%

Actual payouts can range from 0% of target awards for below-threshold results up to 200% of target awards at maximum levels and are determined on the basis of straight-line mathematical interpolation.

The table below shows the threshold, target and maximum performance goals for 2025 as well as actual results:


($ in millions)	2025 AIP Performance Goals and Results					Results
Performance Metric	Weighting	Threshold (Funds 25%)	Target (Funds 100%)	Maximum (Funds 200%)	2025 Actual Performance	% of Target Award Earned
Adjusted EBIT(1)	70.0%	$130.0	$156.0	$180.0	$115.9	0.0%
VAS	15.0%	$1,050.0	$1,105.0	$1,215.0	$1,046.2	0.0%
SFCF	15.0%	$80.0	$100.0	$120.0	$73.6	0.0%
					Total	0.0%

(1) Actual 2025 adjusted EBIT for incentive compensation purposes excludes the impact of non-recurring items which in 2025 were primarily related to restructuring and cost reductions, start up resources and scrap, business transformation costs as well as an Electronic Materials inventory adjustment. See Appendix B for a reconciliation of non-GAAP to GAAP financial measures.

The Company's adjusted EBIT, used for incentive compensation purposes, was $115.9 million in 2025, which was below target performance, resulting in a weighted earned payout of 0.00% of target for that portion of the award opportunity. VAS growth was $1,046.20, which was below target performance, resulting in a weighted earned payout of 0.00% of target for

that portion of the award opportunity. SFCF was $73.6 million, which was below target performance, resulting in a weighted earned payout of 0.00% of target for that portion of the award opportunity.

The Committee aims for incentive compensation payouts to align with Materion's strategic priorities. While annual bonus payouts are entirely based on financial performance, the Committee retains discretion to reduce awards based on qualitative factors such as safety, sustainability, regulatory compliance, and risk management. If performance in an area falls short (e.g., significant safety incident, environmental non-compliance), payouts may be reduced. No such adjustment was made in 2025.

In 2025, participating NEOs earned total AIP awards at a 0.0% level. The table below shows the total 2025 AIP awards earned as a result of the adjusted EBIT, VAS growth, and SFCF performance compared to goals:



	AIP Target			AIP Payout as a % of Target	Total AIP Payout
Name	% Base Salary	$
Jugal K. Vijayvargiya	110%	$	1,100,000	0%	$	0
Shelly M. Chadwick	70%	372,750		0%	$	0
Gregory R. Chemnitz	56%	283,304		0%	$	0

The chart below shows the Externally reported adjusted EBIT Performance & AIP payout as a percentage of target to executives for each of the last five years.

Long-term Incentive Equity-based Awards

General

Target LTI award values are determined based on consideration of market data, as well as the experience, responsibilities and performance of each executive. The outstanding equity grants currently held by each NEO are not taken into consideration in making new grants to that NEO.

LTI Award Vehicles and Grants Made in 2025

The LTI program for 2025 had four components and included:

•Stock Appreciation Rights (SARs), which are granted at fair market value and appreciate in value based on increases in our share price and, consequently, the capital appreciation achieved for shareholders. The SARs generally vest one-third on each of the first three anniversaries of the grant date, subject to the NEO's continued service with us on such date, and subject to accelerated vesting in certain circumstances as described below in “Potential Payments Upon Termination or Change in Control”. The SARs have a term of seven years during which they can be exercised if vested and are settled (when exercised) in shares. The SARs will expire if not exercised prior to the end of the seven-year term.

•Restricted Stock Units (RSUs), which are designed for retention purposes and are earned by our NEOs based on the passage of time and continued employment. The RSUs generally vest one-third on each of the first three anniversaries of the grant date, subject to the NEO's continued service with us on such date, and are settled in shares, subject to accelerated vesting in certain circumstances as described below in “Potential Payments Upon Termination or Change in Control”. Ms. Chadwick's 2025 RSU grant was succeeded in August by a special grant in recognition of her contributions to Materion and for retention purposes, valued at $500,000, that will generally "cliff" vest on the third anniversary of the grant date.

•Performance-based Restricted Stock Units (RTSR PRSUs), which are tied to our Total Shareholder Return (TSR) over three years versus the TSR of our comparison group (identified above under "Peer Group Companies"). These awards are intended to align executive pay with long-term shareholder value creation and RTSR performance. RTSR PRSUs generally vest at the end of the performance period, contingent on the NEO still being employed with us on such date, subject to accelerated vesting in certain circumstances as described below in “Potential Payments Upon Termination or Change in Control”. Any earned RTSR PRSU awards are settled in stock. Award funding can range from 0% to 200% of target levels, based on our three-year TSR positioning relative to comparison group as shown in the table below:

•Performance-based Restricted Stock Units (ROIC PRSUs), are tied to our average ROIC for 2025, 2026 and 2027. These ROIC PRSU awards are intended to further align executive pay with Company performance over a multi-year period, as measured by ROIC, which we believe correlates with long-term shareholder value creation. ROIC PRSUs generally vest at the end of the performance period, contingent on the NEO still being employed with us on such date, subject to accelerated vesting in certain circumstances as described below in “Potential Payments Upon Termination or Change in Control”. Any earned ROIC PRSUs are settled in stock. Award funding can range from 0% to 200% of target levels, as shown in the table below:

The target long-term incentive vehicle mix approved for fiscal year 2025 grants is shown in the following chart:

For both RTSR PRSU and ROIC PRSU awards, funding levels for results in between designated performance levels will be determined using straight-line mathematical interpolation. The actual value of these awards will be based on the number of shares earned, if any, and our corresponding stock price at the time of settlement. No dividend equivalents will be paid on any unearned PRSUs.

The table below shows the various equity grants in 2025 and their associated grant date fair values for the NEOs:


Name	2025 Equity Grants (# of shares)				2025 Equity Grants (Grant Date Fair Values)								Total Grant Date Fair Value
	SARs	RTSR PRSUs	ROIC PRSUs	RSUs (1)	SARs		RTSR PRSUs		ROIC PRSUs		RSUs (1)
Jugal K. Vijayvargiya	29,621	10,039	10,039	10,039	$	779,921	$	1,206,086	$	877,007	$	877,007	$	3,740,021
Shelly M. Chadwick	6,517	2,209	2,209	9,113	$	171,593	$	265,389	$	192,978	$	885,853	$	1,515,813
Gregory R. Chemnitz	3,051	1,034	1,034	2,068	$	80,333	$	124,225	$	90,330	$	180,660	$	475,548

(1) For Ms. Chadwick, amounts in this column include an award of 4,417 RSUs made as part of her regular annual grant and 4,696 RSUs made as a special grant in 2025 (as described above).

Grant date fair values shown above for SARs reflect the Company's fair value assumptions, and are calculated using the Black-Scholes pricing model, which is used for accounting expense recognition purposes.

The Committee is solely responsible for granting equity awards. The awards traditionally are granted in early March after the Company's annual earnings have been announced. Equity grants for 2025 were made to Mr. Vijayvargiya, Ms. Chadwick and Mr. Chemnitz on March 1, 2025. Regular equity grant target award values are based on a dollar value for Mr. Vijayvargiya $4,000,000, Ms. Chadwick $1,100,000 and Mr. Chemnitz $515,000.

The Committee has adopted Stock Award Administrative Procedure Guidelines related to the various forms of equity grants designed to formalize the process of establishing the date of grant, grant prices at fair market value, and other administrative practices appropriate for equity grants to executives. There is no relationship between the timing of the granting of awards and our release of material non-public information, and under the Company’s policies and practices, the Committee has identified a fixed date of March 1 upon which annual grants will generally be made. SARs (including those granted to our NEOs) are generally approved as part of annual award opportunities at a regularly scheduled Committee meeting during February of each year, and are granted on the following March 1. All such SARs are generally granted under our shareholder-approved plan and with an exercise price equal to the closing market price of the Company’s common shares on the date of grant. As a general matter, the Committee does not take material nonpublic information into account when determining the timing and terms of such SARs awards. Due to the grant timing described above, grants are made generally during open trading windows. This grant timing is used to provide for a routine and regular grant practice regarding all employees’ SARs, and in order to make sure that material nonpublic information is not a factor in decisions about the timing or size of SARs grants. To minimize the impact of daily stock price volatility, equity grant calculations are based on our average closing stock price for the last full month ending at least ten business days prior to the grant date. Equity grant levels shown above were based on our average closing stock price in January 2025 of $99.61, which differs from the grant date fair values for such awards. In 2025, the Company did not time the disclosure of material nonpublic information for the purpose of affecting the value of executive compensation, and the Company did not grant SARs to any NEO during any period beginning four business days before and ending one business day after the filing of any Company periodic report on Form 10-Q or Form 10-K, or the filing or furnishing of any Company Form 8-K that disclosed any material nonpublic information.

Under the terms of the LTI awards, our NEOs are required to forfeit outstanding awards and pay back any amounts realized from equity grants if they engage in activity deemed to be detrimental to the Company, as defined in the applicable equity award agreements. Any gains on equity grants are also subject to our clawback policies.

Grants Made in 2023 and Payout of 2023 PRSUs

The performance period for the PRSUs granted in 2023 (RTSR and ROIC) ended on December 31, 2025. Award funding for RTSR PRSUs was based on our three-year TSR positioning relative to a peer group (as listed in the Proxy Statement filed in 2024) as follows: performance below the 25th percentile would fund 0% of the target award; performance at the 25th percentile would fund 50% of the target award; performance at the 50th percentile would fund 100% of the target award; and performance at or above the 80th percentile would fund 200% of the target award. Funding levels for results between the designated performance levels were determined using straight-line mathematical interpolation. Our three-year TSR positioning relative to our peer group for the 2023 RTSR PRSUs was at the 89th percentile, resulting in an award payout equal to 200.0% of target award opportunity. Award funding for ROIC PRSUs ranged from 0% to 200% of target as follows: performance of 10.2% ROIC would fund 50% of the target award; performance of 12.8% ROIC would fund 100% of the target award; and performance at or above 15.4% ROIC would fund 200% of the target award. No PRSUs would be earned for performance below the threshold level of 10.2% ROIC. Funding levels for results in between designated performance levels were determined using straight-line mathematical interpolation. Our ROIC as measured by our average ROIC for 2023, 2024 and 2025 was 9.3% resulting in an award payout equal to 0.0% of target award opportunity for the 2023 ROIC PRSUs. For the PRSUs, Mr. Vijayvargiya earned 16,668 units, Ms. Chadwick earned 3,554 units and Mr. Chemnitz earned 2,196 units. All amounts include earned share dividend equivalents.

The table below shows the performance unit payout history over the last five years.


Grant Date	Three Year Performance Period	Actual Payout % - Combined	Percentile Rank - RTSR
2023	2023 - 2025	100.0%	88.6%
2022	2022 - 2024	90.0%	57.8%
2021	2021 - 2023	149.0%	78.0%
2020	2020 - 2022	111.0%	71.5%
2019	2019 - 2021	130.0%	67.7%

Other Policies, Practices and Guidelines

Severance Agreements

Mr. Vijayvargiya and Ms. Chadwick are party to a Severance Agreement that provides 18 months and 12 months, respectively, of severance benefits in the event of an involuntary termination of employment by the Company, other than for cause (as defined in the Severance Agreement) or due to death or disability (or due to certain resignations as described in the Severance Agreement). Mr. Chemnitz is also a party to a Severance Agreement providing for severance benefits in

other specified circumstances, as described below. These Severance Agreements were adopted to help retain top level executives.

The Severance Agreements provide Mr. Vijayvargiya, Ms. Chadwick, and Mr. Chemnitz with benefits upon certain qualifying terminations of employment following a change in control. The triggering events for a change in control are described in the section entitled “Potential Payments Upon Termination or Change in Control” below and were designed to be competitive and reasonable based primarily on advice from legal counsel as well as the experience of our directors. If Ms. Chadwick or Mr. Vijayvargiya resign for “good reason” (as described in the Severance Agreement), or their employment is (or was) terminated by the Company for reasons other than for cause, in either case, during the two-year period following a change in control (or due to death or disability), the Severance Agreement generally provides for two years of severance benefits. Under the same circumstances, Mr. Chemnitz will receive essentially three years of severance benefits. The potential severance benefits for Mr. Vijayvargiya. Ms. Chadwick and Mr. Chemnitz are described below under “Potential Payments Upon Termination or Change in Control”.

None of the Severance Agreements provides for any excise tax "gross-up" provisions for the “parachute tax” under Code Section 280G. The Committee has confirmed its intent not to enter into any new Severance Agreements that include such a provision.

The Committee believes the Severance Agreements are an important part of the competitive executive compensation package because they help ensure the continuity and stability of executive management and provide protection to the NEOs. The Committee also believes the Severance Agreements reduce the NEOs' interest in working against a potential change in control and help to minimize interruptions in business operations by reducing any concerns they have of being terminated prematurely and without cause during an ownership transition. The Company benefits from these agreements in that in exchange for the protections offered, each NEO agrees to:

•Refrain from competing while employed and for two years after a termination of employment;

•Refrain from soliciting any employees, agents or consultants to terminate their relationship with us;

•Protect our confidential information; and

•Assign to the Company any intellectual property rights to any discoveries, inventions or improvements made while employed by us and within two years (one year for Mr. Chemnitz) after employment terminates.

Materion Non-CIC Severance Policy

Mr. Chemnitz is eligible for 12 months of severance benefits in the event of an involuntary termination of employment by the Company, other than for cause or due to death or disability. The triggering events for an involuntary termination are described in the section entitled “Potential Payments Upon Termination or Change in Control” below and were designed to be competitive and reasonable based primarily on advice from FW Cook, legal counsel and the experience of our directors.

Retirement Benefits

We provide retirement and deferred compensation benefits to our NEOs under certain Company plans and arrangements, including the:

•Materion Corporation Pension Plan (Pension Plan);

•Materion Corporation Supplemental Retirement Benefit Plan (SRBP);

•Materion Corporation Retirement Savings Plan (401(k) Plan); and

•Materion Corporation Executive Deferred Compensation Plan (MEDCP).

Prior to 2011, we provided special awards under a plan (further described below in connection with the SRBP) that was designed to supplement the retirement benefits provided under the Pension Plan for participating NEOs. These special awards were eliminated at the end of 2010, with the SRBP assuming the same role beginning in 2011. The Committee believes each of these programs is necessary from a competitive standpoint (because many companies with whom we compete for talent offer similar retirement benefits) and for retention purposes.

Pension Plan

The Pension Plan is a tax-qualified defined benefit pension plan that provides retirement compensation to approximately 22% of our U.S. employees. Mr. Chemnitz is the only NEO that participates in the Pension Plan, as this plan was closed to new employees hired after May 25, 2012. Before June 1, 2005, the benefit formula under the Pension Plan was 50% of the final average earnings over the highest five consecutive years minus 50% of the annual Social Security benefit, with the

result prorated for service of less than 35 years. Effective as of May 31, 2005, we froze the benefit under the prior formula for all employees. Mr. Chemnitz did not earn a benefit under this formula.

In 2015, the Board amended the Pension Plan effective January 1, 2016, to allow participants to elect a lump sum payment, limited to $100,000, following termination in lieu of a future annuity.

Effective December 31, 2019, we froze accruals under the Pension Plan for all employees and enhanced the 401(k) Plan for all participants to provide a matching contribution of $1.00 for each dollar contributed up to 4% of compensation deferred by the participant and an annual non-elective contribution based on total cash compensation and the participant’s age, both subject to applicable annual Code limitations.

The Code limitations associated with the Pension Plan are considered by the Committee in determining amounts intended to supplement retirement income for Mr. Chemnitz, such as the SRBP and the MEDCP described below. The benefit accumulated under the Pension Plan does not affect any other element of compensation for Mr. Chemnitz, except to the extent it is included in the calculation of payments that may be paid upon a change in control or other potential severance payments, as described below in “Potential Payments Upon Termination or Change in Control”.

SRBP

The Committee and the Board approved the SRBP and it became effective in September 2011. The SRBP is an unfunded, non-qualified deferred compensation plan that provides retirement benefits for a select group of management or highly compensated employees to supplement the pension benefits paid to them from the Pension Plan.

Through 2010, the Committee made special awards to participating NEOs to provide supplemental retirement compensation because of the limitations imposed under the Code, which place caps on the amount of eligible compensation used for purposes of determining benefit amounts under the Pension Plan. Special awards were current, taxable annual payments made to participating NEOs to take the place of a traditional supplemental executive retirement plan. The Committee elected to replace the special awards with the SRBP because the circumstances that gave rise to the special awards concept have changed and become more favorable to the use of a traditional supplemental executive retirement plan. In 2025, Mr. Chemnitz was the only member of senior management who participated in the SRBP before the Pension Plan was closed to new hires on May 25, 2012. Mr. Chemnitz was named as a participant in the SRBP in 2012, with all service included since his hire date in September 2007. Since Mr. Chemnitz did not receive any special awards, his Offset Amount (as explained below) is zero.

Mr. Chemnitz's benefit under the SRBP will be the amount of his “Prevented Benefits” (as described below), reduced by his designated “Offset Amount” (in other words, the total amount that was paid to him in prior years as special award payments), as set forth in the SRBP. Mr. Chemnitz's interest in benefits payable under the SRBP will be vested and non-forfeitable to the same extent and in the same manner as benefits are vested and non-forfeitable under the Pension Plan. The benefits payable under the SRBP will be paid to Mr. Chemnitz in a single sum payment on or about the first day of the third month next following the date of his separation from service, or in certain cases as necessitated by Section 409A of the Code, the first business day of the month that is at least six months after his separation from service.

“Prevented Benefits” for purposes of the SRBP means the difference, expressed as a single sum, between the regular pension benefits payable to Mr. Chemnitz under the Pension Plan and the regular pension benefits that would be so payable to him under the Pension Plan if such benefits were determined based on the inclusion of any compensation that was deferred on an elective basis under any non-qualified deferred compensation plan or agreement with an employer and without regard to limitations on covered compensation and benefit amounts imposed by the Code and taking into account any special calculation provisions for him as set forth on Schedule I to the SRBP.

Consistent with the Pension Plan, effective December 31, 2019, we froze accruals under the SRBP for all participants.

401(k) Plan

The 401(k) Plan is a tax-qualified defined contribution plan. All of the NEOs participate in this plan, which we offer as part of a competitive total compensation package. The 401(k) Plan provides the NEOs and all other eligible employees with the opportunity to defer eligible compensation (on a pre-tax basis) up to specified limits imposed by the Code. In 2025, we made a matching contribution to each participant of $1.00 for each dollar contributed up to 4% of compensation deferred by the participant, and an annual non-elective contribution based on total cash compensation and the participant’s age, both subject to applicable annual Code limitations.

MEDCP

The MEDCP, which is described below in the section entitled “2025 Non-qualified Deferred Compensation,” provides an opportunity for the NEOs to defer a portion of their compensation and represents an element of what we consider a competitive total compensation package for the NEOs.

Health and Welfare Benefits

The NEOs participate in group life, health and disability programs on the same terms as provided to all salaried employees.

Perquisites

Except for periodic executive physicals, which the Committee views as an element of a competitive total compensation package, no perquisites or personal benefits are provided to the NEOs.

Accounting and Tax Effects

Section 162(m) of the Code generally disallows a federal income tax deduction to public companies like Materion for compensation in excess of $1 million paid to certain current or former executive officers. In making its compensation decisions, the Committee retains the flexibility to award compensation that is consistent with our objectives and philosophy even if it does not qualify for a tax deduction. The Committee believes that the tax deduction limitation should not be permitted to compromise our ability to design and maintain executive compensation arrangements that will attract and retain the executive talent needed to compete successfully. Accordingly, achieving the desired flexibility in the design and delivery of compensation may result in compensation that in certain cases is not deductible for federal income tax purposes.

Stock Ownership Guidelines

The Committee maintains mandatory stock ownership guidelines for executive officers, including our NEOs. The stock ownership guidelines require our covered NEOs to own qualifying shares with targeted values equal to six times base salary for Mr. Vijayvargiya, three times base salary for Ms. Chadwick and equal to base salary for Mr. Chemnitz.

The Committee also maintains stock ownership guidelines for all non-employee directors, requiring them to own qualifying shares with targeted values equal to six times their annual board cash retainer. These guidelines were established by the Committee to promote long-term stock ownership and further align executive and shareholder interests. Executives, including covered NEOs, and non-employee directors, have five years, from the time they are first subject to these guidelines, to achieve targeted ownership levels. The stock ownership guidelines for executive officers and non-employee directors are available under the "Corporate Governance" tab at http://materion.com.

Until guidelines are met, executive officers, including our covered NEOs and non-employee directors are subject to holding requirements as outlined below:


Position			Retention Ratio
Chief Executive Officer and Non-employee Directors			75% of net shares acquired under equity awards will be held until the applicable guideline has been achieved.
Other NEOs			50% of net shares acquired under equity awards will be held until the applicable guideline has been achieved.

Shares that count towards ownership requirements include common shares held directly or indirectly, shares in employee benefit plans, and the after-tax value of unvested time-based RSUs. Unvested PRSUs, vested/unexercised SARs, and unvested SARs do not count toward ownership requirements. Qualifying shares are valued based on our average closing stock price for the last twenty trading days of each year. Once the required ownership level is met as of any annual measurement date, an executive is deemed to be in ongoing compliance with the guidelines as long as he or she continues to own at least the same number of qualifying shares as when the guideline was originally achieved. If an executive fails to achieve the guidelines within the designated five-year compliance period, the Committee has the discretion to take any action deemed appropriate. As of December 31, 2025, all covered NEOs met the ownership guidelines. All non-employee directors have met the ownership guidelines and all non-employee directors who have been directors for at least one year own Company stock.

Anti-hedging/Pledging

Under our Directors, Officers & Key Employees Insider Trading Policy, we prohibit executive officers, directors, and certain other key employees from purchasing any financial instrument or engaging in any other transaction, such as a prepaid variable forward contract, equity swap, collar or exchange fund, that is designed to hedge or offset any decrease in the market value of Company securities. The policy also prohibits insiders from holding Company securities in a margin account or pledging Company securities as collateral for a loan.

Insider Trading Policies

We have adopted insider trading policies and procedures applicable to our executive officers, directors and employees, and have implemented processes for the Company, that we believe are reasonably designed to promote compliance with insider trading laws, rules and regulations, and the New York Stock Exchange standards. Copies of our Directors, Officers & Key Employees Insider Trading Policy and our Insider Trading Policy are filed as exhibits to our Annual Report on Form 10-K for the year ended December 31, 2025.

Clawback Policy

The Company maintains and operates a Compensation Clawback Policy for the company to comply with both the new clawback listing standards of the New York Stock Exchange and rules and regulations promulgated by the U.S. Securities and Exchange Commission. This policy is in addition to the clawback provisions contained in our equity award agreements that require awardees to forfeit outstanding awards and pay back any amounts from equity grants if they engage in certain activity deemed to be detrimental to the Company. The Committee recognizes that maintaining a clawback policy represents an important protection for shareholders and is an important component of strong corporate governance.

The Compensation Clawback Policy provides for the reasonably prompt recovery (or clawback) of certain excess incentive-based compensation received during an applicable three-year recovery period by current or former executive officers in the event the Company is required to prepare an accounting restatement due to the material noncompliance with any financial reporting requirement under the securities laws. Triggering events include accounting restatements to correct an error in previously issued financial statements that is material to such previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. Excess incentive-based compensation for these purposes generally means the amount of incentive-based compensation received (on or after October 2, 2023) by such executive officer that exceeds the amount of incentive-based compensation that would have been received by such executive officer had it been determined based on the restated amounts, without regard to any taxes paid. Incentive-based compensation potentially subject to recovery under the mandatory accounting restatement provisions of the Compensation Clawback Policy is generally limited to any compensation granted, earned or vested based wholly or in part on the attainment of one or more financial reporting measures.

In general, the Company may utilize a broad range of recoupment methods under the Compensation Clawback Policy for mandatory accounting restatement clawbacks. The Compensation Clawback Policy does not condition such clawback on the fault of the executive officer, but the Company is not required to clawback amounts in limited circumstances where the Compensation Committee has made a determination that recovery would be impracticable and (1) the Company has already attempted to recover such amounts but the direct expense paid to a third party in an effort to enforce the Compensation Clawback Policy would exceed the amount to be recovered, (2) the recovery of amounts would violate applicable home country law, or (3) the recovery would likely cause the non-compliance of a tax-qualified retirement plan under the Internal Revenue Code of 1986, as amended, and applicable regulations. Operation of the mandatory accounting restatement provisions of the Compensation Clawback Policy is subject to a brief phase-in process during the first few years after its effectiveness. The Company may not indemnify any such executive officer against the loss of such recovered compensation in the event of a mandatory accounting restatement.

In connection with the adoption of the Compensation Clawback Policy, the Board amended and revised in its entirety the Company’s predecessor 2011 Clawback Policy, as amended and restated, in the form of the Supplemental Clawback Policy. The Supplemental Clawback Policy operates, effective October 2, 2023, separate and distinct from (but in addition to) the Compensation Clawback Policy. In general, under the Supplemental Clawback Policy, if we are required to prepare an accounting restatement due to material noncompliance with financial reporting requirements under federal securities laws, we will use all reasonable efforts to recover, from persons currently or formerly covered by the policy (the Company’s executive and Section 16 officers, and the Company’s executive staff as identified by the Committee, including the NEOs, as described in the policy), excess incentive-based compensation to the extent that such persons, in our determination, willfully committed an act of fraud, dishonesty or recklessness regarding their duties that contributed to such noncompliance (“Misconduct”). For these purposes, excess incentive-based compensation means any incentive-based compensation (for example, annual incentives, performance-based equity awards, and other incentive compensation as described in the policy) paid or granted by us to such persons after 2010 in excess of what they should have been paid or granted had our financial statements been correct in the first place. For certain equity awards not subject to the Supplemental Clawback Policy, if any covered officer engages in Misconduct in connection with such a restatement, the Committee may determine that clawback pursuant to the detrimental conduct provisions of such awards may also be carried out. There shall be no duplication of recovery under the Compensation Clawback Policy and the Supplemental Clawback Policy.

Compensation Policies and Practices - Risk Management

In setting compensation, the Committee considers the risks to Materion's shareholders and to the achievement of our goals that may be inherent in the compensation program. Although a significant portion of our executives' compensation is performance-based and “at-risk,” we believe our executive and employee compensation plans, policies and programs, are appropriately structured and are not reasonably likely to result in a material adverse effect on the Company.

In its review, the Committee noted that:

•Incentive plans provide for balance in that performance measures and goals are tied to the Company's strategic objectives, achievable financial performance centered on the Company's expectations, relative performance against a peer group of companies and specific individual goals;

•A significant portion of variable compensation is delivered in equity (SARs, PRSUs and RSUs) with multi-year vesting. The Company believes that equity compensation helps reduce compensation risk by balancing financial or strategic goals against any other factors management may take into consideration to promote long-term shareholder value;

•Materion has structured incentive plans that provide appropriate upside opportunity while minimizing incentives for management to pursue short-term financial performance at the expense of long-term shareholder value;

•The Company has adopted stock ownership guidelines that include share retention requirements until guidelines are met, to encourage a focus on long-term growth rather than short-term gains;

•The Company extended the scope of its Clawback Policy to recoup from culpable NEOs any gains that are later found to be based on erroneous financial statements; and

•NEO Tally Sheets, summarizing annual compensation, benefits, stock gains, accumulated wealth and contingent awards and benefits are reviewed by the Committee annually.

In addition, under the guidance of FW Cook, the Company conducted a comprehensive risk assessment of its 2025 incentive plans. The assessment results, as reviewed by the Committee, indicated that from a compensation risk perspective, there were no significant risk areas. The two incentive plans in which the NEOs participate (in other words, the AIP and LTIP) were considered "low risk" and well-aligned with sound compensation design principles that provide a balanced approach for delivering incentives at various levels of performance.
