董事会主席的信

2026 年 10 月 9 日

亲爱的 Coherent 股东

2026 财年是 Coherent 又一个非凡的年份，实现了创纪录的收入和显著的利润率扩张。Coherent 在推动行业领导者在数据中心、通信和先进制造领域推进下一代技术方面发挥着日益关键的作用。这些成就体现了我们全球团队的承诺以及我们在为 Coherent 的下一阶段加速增长和持续创新奠定基础方面取得的进展。

在光子学领域扩展我们的全球领导地位

\n 通过有意识地将我们的业务、投资和能力集中在Coherent增长最快的机会上，我们建立了一家更强大、更盈利的公司，并增强了为股东创造价值的能力。在我们世界级高管团队的指导下，我们推进了一个广泛的光子学产品组合，这对AI数据中心的性能、效率和可扩展性至关重要。我们2026财年的强劲业绩，包括全年营收71.2亿美元，较上一年增长22.5%，证明了我们战略的力量和执行的纪律性。 \n

\n 在数据中心和通信业务强劲增长的基础上，我们继续投资于满足我们技术加速需求所需的合作伙伴关系、创新和产能。我们最近签署了一份意向书，根据《芯片与科学法案》获得最高5000万美元的直接资金，用于扩建位于德克萨斯州谢尔曼的6英寸磷化铟制造设施。这项计划中的扩建将显著增加关键AI使能技术的国内生产，并进一步加强我们的制造能力。 \n

Coherent的非凡机遇即将到来

\n Coherent的董事会正在积极监督公司增长战略的重要进展，以确保我们把握住前方的技术机遇并为股东创造价值。当前的董事会成员汇集了在技术、运营以及材料、半导体、网络和激光行业具有关键专业知识的领导者，为监督Coherent不断演变的业务重点提供了必要的技能和视角。 \n

\n 我们2026财年的成就为Coherent开启了更加激动人心的新篇章。我们在财年开始时就面临强劲的客户需求，扩大了生产，并有多个新的增长平台预计在接下来的季度中逐步启动，这些都得到了技术领导力和制造规模的有力支持。 \n

\n Coherent正在塑造技术的未来，我们专注于将这种领导力转化为对股东的持久价值。 \n

\n 我们感谢您持续的投资和支持。 \n

DIRECTOR INDEPENDENCE AND CORPORATE GOVERNANCE POLICIES

\n The Company’s Common Stock is listed on the New York Stock Exchange (the “NYSE”). The rules of the NYSE require that a majority of the Company’s Board be Independent Directors (as defined in the NYSE’s rules). Our Corporate Governance Guidelines further provide that a substantial majority of the members of the Company’s Board must qualify as independent. The Board has determined that all of the continuing directors or nominees for election as director are independent within the meaning of the NYSE’s rules, other than Mr. Anderson. In its annual review of director independence, the Board considers all commercial, banking, consulting, legal, accounting, or other business relationships any director may have with the Company to determine whether any director has a material relationship with the Company. The Board considers a “material relationship” to be one that impairs or inhibits, or has the potential to impair or inhibit, a director’s exercise of critical and disinterested judgment on behalf of the Company. When assessing the “materiality” of a director’s relationship with the Company, the Board considers all relevant facts and circumstances, from both the standpoint of the director in his or her individual capacity, and from the standpoint of the director’s family and other affiliations. In addition, the NCG Committee facilitates annual self-evaluations of the Board, the Audit and Risk Committee, the Compensation and Human Capital Committee, and the NCG Committee in order to determine whether the Board and such Committees are functioning effectively. The Company is in compliance with all applicable governance requirements of the NYSE. \n

SHAREHOLDER ENGAGEMENT

\n The Coherent Board values transparent and ongoing engagement with our shareholders and has maintained a long-standing practice of robust shareholder engagement to ensure investor priorities and perspectives are directly communicated to the Board. Throughout the course of the year, we stay connected with shareholders through discussions on a wide variety of business topics, including strategy, executive compensation, leadership development, succession planning and sustainability. We believe our engagements with shareholders have been constructive and have provided management and the Board with insights into issues and initiatives that are important to our shareholders. \n

\n We communicate with our shareholders through a variety of means, including direct interface, investor presentations, investor conferences, analyst meetings, one-on-one meetings, our website and publications that we issue. We also initiate formal outreach efforts prior to our annual meeting of shareholders. Through that process, we contact shareholders and invite them to engage in discussions on a variety of topics, including our Proxy Statement disclosures. \n

RISK MANAGEMENT AND MITIGATION

\n The Board is responsible for risk management oversight, including our Enterprise Risk Management (“ERM”) program. The Board has delegated primary oversight of key risk areas to each of the Board Committees as described below. \n

\n Our ERM program is designed to facilitate the identification, assessment, management, and monitoring of material risks the Company may face over the short term and long term and provide regular communication with our Board and its committees regarding these risks. Key risks are raised by management to the Audit and Risk Committee. At least annually, our Vice President of Internal Audit reports to the Audit and Risk Committee on our enterprise risk assessment. Our Board consults with outside advisors and members of management to help monitor trends, identify potential threats, and assess the Company’s risk environment. Risk areas identified in the ERM process help inform how we present the risks facing the Company in the “Risk Factors” section of our fiscal year 2026 Annual Report on Form 10-K, which is also reviewed by the Audit and Risk Committee. \n

MANAGEMENT SUCCESSION PLANNING

\n Our Board is responsible for the development and regular review of a comprehensive succession plan for our CEO and senior management. Our Board believes that the full Board, including our CEO, should be actively engaged and involved in CEO and senior management succession planning, with the goal of business and operational continuity and sustaining the Company’s strong track record of increasing shareholder value. In general, the Board’s management succession planning is designed to anticipate both “planned” successions, such as those arising from anticipated retirements, and unplanned succession events, including emergencies and a range of other potential contingencies. Our Board has adopted an emergency succession plan to facilitate the transition to both interim and long-term leadership in the event of an unexpected vacancy in the position of CEO. \n

\n Our CEO and Chief People Officer supports the annual succession plan review conducted by the Board by providing information about each executive role and succession scenarios, including an overview of each potential successor’s experience and potential, readiness assessment and planned leadership development opportunities. The independent members of the Board also regularly interact with employees across several levels of seniority through management presentations at Board meetings and other informal events to form their own independent assessment of senior leaders. \n

\n Our Board, including our CEO, also regularly reviews senior management succession planning and the composition of senior management with our Chief People Officer. If the succession plan is triggered for a member of senior management, our Board would participate in the discussion and consideration of any action with our CEO and Chief People Officer. \n

NOMINATION OF CANDIDATES FOR DIRECTOR

\n The Company considers director candidates from several sources, including existing directors, members of the Company’s management team, shareholders, and third-party search firms. The Company’s current bylaws describe the procedures by which shareholders may recommend candidates for election to the Board. In general, shareholder nominations must be made in writing, and notice of a nomination must be given to our Secretary no earlier than the close of business on the 150th day, and no later than the close of business on the 120th day, before the anniversary date of the previous year’s annual meeting. If the date of the annual meeting is changed by more than 30 days from the first anniversary date of the previous year’s annual meeting, the notice must be delivered no earlier than the close of business on the 120th day before the annual meeting and no later than the close of business on the later of (i) the 90th day before the annual meeting or (ii) the 10th day following the day on which public announcement of the date of the meeting is first made. In addition, a notice of nomination must include information regarding both the nominating shareholder and each director nominee as set forth in the Company’s bylaws, including: \n

\n COHERENT PROXY STATEMENT 2026 | 25

\n •\n
\n

\n \n their relationship to each other; \n

\n •\n
\n

\n \n any understanding between them regarding the nomination; \n

\n •\n
\n

\n \n the shares owned by the nominating shareholder; and \n

\n •\n
\n

\n \n other information concerning the nominating shareholder and/or each nominee that is required for inclusion in a proxy statement filed with the Securities and Exchange Commission (the “SEC”). \n

\n Further, to be eligible for election as a director of the Company, the nominee must deliver within the timeframe noted above a written questionnaire detailing his or her background and qualifications, and a written representation and agreement as set forth in the Company’s bylaws. The form for this representation and agreement will be provided by the Secretary of the Company upon written request. \n

\n The NCG Committee considers a variety of factors when determining whether to recommend a nominee for election to the Board, including those factors set forth in the Company’s Corporate Governance Guidelines. In general, candidates nominated for election to the Board should possess the following qualifications: \n

\n •\n
\n

\n \n high personal and professional ethics, integrity, practical wisdom and mature judgment; \n

\n •\n
\n

\n \n broad training and experience in policy-making decisions in business; \n

\n •\n
\n

\n \n professional expertise and skill set that is useful to the Company, and complementary to the background and experience of the other directors; \n

\n •\n
\n

\n \n willingness to devote the amount of time necessary to carry out the duties and responsibilities of a director; \n

\n •\n
\n

\n \n commitment to serve on the Board over a period of multiple years in order to develop knowledge about the Company and its operations; \n

\n •\n
\n

\n \n willingness to represent the best interests of all stakeholders and objectively appraise management performance; and \n

\n •\n
\n

\n \n compliance with the Company’s independence requirements. \n

\n Potential candidates are screened and interviewed by a selection committee appointed by the NCG Committee. \n

\n The NCG Committee’s practice is to review the skills, experiences, and attributes of individual Board members and candidates given the current make-up of the Board, to ensure that the Board includes individuals who will serve the Company’s strategic and governance needs. We consider the Company’s current business priorities when evaluating a broad range of experience, knowledge, talents and perspectives that may be needed on the Board. Candidates are also evaluated on their broad-based business knowledge and contacts, prominence, commitment to ethical and moral values, personal and professional integrity, sound reputation in their respective fields, as well as a global business perspective and commitment to corporate citizenship. \n

SIZE OF THE BOARD

\n As provided in the Company’s bylaws, the Board is to be composed of no less than five and no more than fourteen members, with the exact number determined by the Board based on its current composition and requirements. The Board currently consists of fourteen members. \n

\n 26 | COHERENT PROXY STATEMENT 2026

\n Table of Contents\n

BOARD LEADERSHIP STRUCTURE

\n The Board has the flexibility to determine whether it is in the best interests of the Company and its shareholders to separate or combine the roles of Board Chair and CEO at any given time. In making that determination, the Board assesses whether the roles should be separated or combined based on its evaluation of the existing composition of the Board and the circumstances at the time. \n

SEPARATION OF BOARD CHAIR AND CEO

\n Mr. DiGirolamo has served as our independent Chair of the Board since June 2024. The Board believes that this separation of duties strengthens our corporate governance by providing independent leadership of the Board and allowing the Chair to focus more on oversight. Mr. DiGirolamo joined our Board in 2018 and served as our Lead Independent Director from 2022 until his election as Board Chair. \n

BOARD CHAIR RESPONSIBILITIES

\n The responsibilities of the Board Chair include the following: \n

\n •\n
\n

\n \n presides at all meetings of the Board, including meetings of the independent directors held in executive session; \n

\n •\n
\n

\n \n has the authority to call meetings of the independent directors; \n

\n •\n
\n

\n \n serves as a liaison between the CEO and the independent directors; \n

\n •\n
\n

\n \n consults with the CEO on agendas for Board meetings; and \n

\n •\n
\n

\n \n carries out other duties as requested by the NCG Committee, the independent directors, or the Board. \n

COMMUNICATION WITH DIRECTORS

\n Any person wishing to communicate with the Board may send electronic communication addressed to the Board Chair, or to any member of the Board individually, to chair@coherent.com, or a written communication addressed to the Board Chair, or to any member of the Board individually, in care of Coherent Corp., 375 Saxonburg Boulevard, Saxonburg, PA 16056. Any communication addressed to a director that is received by the Company at this address will be delivered or forwarded to the individual director as soon as practicable, except for advertisements, solicitations or other matters unrelated to the Company. The Company will forward communications addressed to the Board Chair and to the chair of the Board committee whose function is most closely related to the subject matter of the communication. \n

DIRECTOR MANDATORY SERVICE CONCLUSION AND SUCCESSION PLANNING

\n The Board has instituted a policy for directors, as set forth in the Company’s Corporate Governance Guidelines. Under this policy, a director must tender a resignation to the NCG Committee, to be effective at the end of the last regularly scheduled Board meeting prior to the director’s 76th birthday. The NCG Committee considers each case and recommends to the Board the action to be taken. The Board in its discretion chooses to accept or reject the resignation. If rejected, the director’s resignation will be deemed to be re-submitted to the NCG Committee annually thereafter, until such time as it is accepted by the Board. The Board undertakes a succession planning process to proactively address anticipated openings on the Board. \n

STANDING BOARD LIMITS

\n Board members are limited to serving on a maximum of four public company boards, including the Board. \n

\n COHERENT PROXY STATEMENT 2026 | 27

CHANGE IN DIRECTOR OCCUPATION

\n Under the Company’s Corporate Governance Guidelines, when a director’s principal occupation or business association changes substantially (including retirement), the director must tender a resignation for consideration by the NCG Committee. The NCG Committee considers whether such change materially affects the director’s qualification to continue serving as a director and recommends to the Board the action to be taken with respect to the resignation. \n

EXECUTIVE SESSIONS OF NON-EMPLOYEE DIRECTORS

\n Executive sessions of independent directors are held regularly, at least twice each fiscal year, with the Board Chair presiding. \n

DIRECTOR ATTENDANCE AT ANNUAL MEETING OF SHAREHOLDERS

This document is available on the Company’s website at www.coherent.com/company/investor-relations/governance.

\n Table of Contents\n

CODE OF ETHICAL BUSINESS CONDUCT

\n The Board has approved and adopted a Code of Ethical Business Conduct (the “Code of Conduct”) applicable to everyone in the Company and its subsidiaries, including the Board. The Code of Conduct also applies to contractors, consultants, temporary workers, suppliers, and other third parties. This document is available on the Company’s website at www.coherent.com/company/investor-relations/governance. The Company will promptly disclose on its website any substantive amendments or waivers with respect to any provision of the Code of Conduct. \n

\n Employees are required and encouraged to report suspected violations of our Code of Conduct. Reports are forwarded for review by the Audit and Risk Committee. \n

COMPANY POLICY PROHIBITING INSIDER TRADING AND SPECULATIVE TRADING, PLEDGING AND HEDGING

We have adopted an insider trading policy and procedures reasonably designed to promote compliance with insider trading laws, rules, and regulations and the listing standards of the New York Stock Exchange and governing the purchase, sale and/or, other disposition (“trading”) of our Common Stock and other securities by our directors, officers and employees and other persons who may have access to material, non-public information about the Company including, without limitation, such person’s spouse and others living in that person’s household. Aside from the blanket restriction on trading while in possession of material non-public information, the insider trading policy also prohibits certain designated insiders (including our directors and Section 16 officers) from trading during blackout windows and, during open trading windows, requires designated insiders to pre-clear their trades. The insider trading policy also prohibits employees from trading in securities of other public companies about which the employee learns material, non-public information.

\n In addition to the above restrictions, the insider trading policy also prohibits certain designated insiders (including our directors and Section 16 officers) from (1) selling Company securities of the same class for at least six months after a purchase, or purchasing Company securities of the same class for at least six months after a sale, (2) selling Company securities short, (3) buying or selling puts, calls, or other derivatives, on the Company’s securities, (4) pledging Company securities, or holding them in a margin account as collateral, and (5) hedging Company securities. The insider trading policy does not specifically define hedging transactions, but they are intended to include the purchase of financial instruments (including prepaid variable forward contracts, equity swaps, collars, and exchange funds), or other transactions that are intended to hedge or offset any decrease in the market value of Company securities held by the individual. \n

\n The foregoing summaries of our insider trading policy and procedures do not purport to be complete and are qualified in their entirety by reference to the full text of our insider trading policy, a copy of which can be found as an exhibit to our Annual Report on Form 10-K for the fiscal year ended June 30, 2026. \n

REVIEW AND APPROVAL OF RELATED PERSON TRANSACTIONS

\n The Company’s policies and procedures regarding related party transactions are included in the Company’s Corporate Governance Guidelines. The Corporate Governance Guidelines require that all Company directors, officers and employees refrain from activities that might involve a conflict of interest. Before making an investment, accepting a position or benefit, participating in a transaction or business arrangement, or otherwise acting in a manner that creates or appears to create a conflict of interest, a full disclosure of all relevant facts and circumstances must be made, and the Audit and Risk Committee’s written approval obtained. The Audit and Risk Committee reviews and approves any transaction between the Company and any related person (as defined in Item 404 of Regulation S-K) and any other potential conflict of interest situations on an ongoing basis. Waivers of actual or potential conflicts of interest for any of the Company’s executive officers or directors may be granted only by the Board. Only those matters that are determined by the Board not to be in conflict with the best interests of the Company may be approved. In fiscal year 2026, we did not conduct any transactions with related persons that would be considered a related party transaction under applicable SEC rules. \n

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

\n During fiscal year 2026, Ms. Sterling, Mr. Pagliuca, Ms. Patrick, Mr. Vij and Dr. Xia served as members of the Compensation and Human Capital Committee. None of them has ever served as an officer or employee of Coherent or has had any relationship with Coherent requiring disclosure under Item 404 of Regulation S-K under the Exchange Act. During fiscal 2026, none of our executive officers served as a member of the board of directors or compensation committee of another entity, any officers of which served on Coherent’s Board or Compensation and Human Capital Committee. \n

DIRECTOR COMPENSATION

\n The Company uses a combination of cash and equity compensation to attract and retain qualified candidates to serve on the Company’s Board. In setting director compensation, the Company consults with its independent compensation advisor, and considers the significant amount of time and skill required for directors to fulfill their overall responsibilities. Director compensation is only paid to non-employee directors. For purposes of this section, all references to “directors” means non-employee directors. \n

\n The director compensation program is periodically (generally every other year) reviewed by the Compensation and Human Capital Committee, with the assistance of its independent compensation advisor, to ensure that the program remains competitive. As part of this review, the types and levels of compensation offered to our directors are compared to those offered by a select group of comparable companies (the “Peer Group”). The Peer Group is the same as those used for the Company’s named executive officers and are listed in the “Compensation Discussion and Analysis” section of this proxy statement. \n

\n The components of our director compensation program for fiscal year 2026 are disclosed below. The Board is compensated based on a role-based compensation program, not on the number of meetings attended. The Compensation and Human Capital Committee strives to set director compensation at levels that are competitive with our Peer Group. \n

DIRECTOR EQUITY PROGRAM

\n In addition to the cash compensation outlined above, directors receive annual equity awards. In setting the total dollar value of the equity awards, the Board takes into account cash compensation, limits in the Company’s equity plan governing documents, recommendations of the Compensation and Human Capital Committee and its independent compensation advisor, and Peer Group practices. In fiscal year 2026 the Board modified the director compensation schedule so that equity \n

\n 30 | COHERENT PROXY STATEMENT 2026

\n Table of Contents\n

\n grants are aligned with the election of directors at the annual meeting. As a result the Board received a prorated equity grant in January 2026 that will vest in November 2026. Beginning in fiscal year 2027 the Board will receive its annual equity grant on the date of the applicable annual meeting, which for fiscal year 2027 will be held in November. \n

\n For fiscal year 2026, the Company determined the number of restricted stock units awarded by dividing the dollar value of the grant by the closing stock price on the grant date, subject to rounding. For fiscal year 2026, the nominal value of the annual equity award for full-year directors was $220,000. Restricted stock unit awards granted to directors generally vest in one year (or, if earlier, on the day before the next annual meeting). They do not automatically vest upon a director’s departure from the Board. The Compensation and Human Capital Committee may recommend, and the Board may in its sole judgment approve, vesting of a restricted stock unit award upon a director’s departure from the Board if the departing director is found to be in good standing at the time of departure. \n

DELINQUENT SECTION 16(A) REPORTS

\n Section 16(a) of the Exchange Act requires the Company’s directors, executive officers and persons who beneficially own more than 10% of a class of the Company’s registered equity securities to file with the SEC and deliver to the Company initial reports of ownership, and reports of changes in ownership, of such securities. We are required to disclose in this proxy statement any failure to file these required ownership reports by their due dates. Based solely on our review of Section 16(a) reports, and written representations that our directors and executive officers have furnished to us, other than two late Form 4 reports for Ilaria Mocciaro, in each case regarding the withholding of shares for tax purposes in connection with the vesting of restricted stock units, and one late Form 4 report for Stephen Pagliuca regarding the granting of a restricted stock award, all of which were due to an administrative error by the Company, we believe that all reporting persons complied with all Section 16(a) filing requirements during our fiscal year 2026. \n

(the “Company”) approve, on an advisory basis, the compensation of the Company’s Named Executive Officers as described and disclosed in the Compensation Discussion and Analysis, the compensation tables, and any related material contained in the proxy statement for the Company’s 2026 Annual Meeting of Shareholders. \n

\n Because this vote is advisory, it will not be binding upon the Board or the Compensation and Human Capital Committee. However, the Compensation and Human Capital Committee will take the outcome of the vote into account when considering future executive compensation arrangements. After this vote, our next “Say-on-Pay” vote will be held at our fiscal year 2027 annual meeting of shareholders. \n

\n The affirmative vote of at least a majority of the votes that all shareholders present at the Annual Meeting, in person or by proxy, are entitled to cast is required to approve on a non-binding advisory basis the compensation of our named executive officers for fiscal year 2026, as disclosed in this proxy statement. Abstentions have the effect of an “AGAINST” vote, and broker non-votes have no effect. \n

\n \n \n \n \n \n \n \n

I. EXECUTIVE SUMMARY

COMPANY OVERVIEW

\n Fiscal year 2026 was an exceptional year for Coherent. We delivered record revenue of $7.1 billion, representing 22.5% year-over-year growth, while expanding GAAP gross margin and generating robust GAAP and non-GAAP earnings per share. These results reflect the strength of our strategy, the disciplined execution of our executive leadership team and the differentiated breadth and scale of our photonics platform. \n

\n We enter fiscal year 2027 with exceptional customer demand, expanding manufacturing capacity and multiple new growth platforms beginning to ramp. Coherent’s broad technology portfolio and global manufacturing scale position us to help enable the performance, bandwidth and energy efficiency required by increasingly large and complex data center networks. We also remain focused on advancing our industrial business, where our differentiated materials and laser technologies support customers across a diverse range of high-value applications. \n

	\n \n Continued review of NEO compensation\n \n			\n The Compensation and Human Capital Committee (the “Committee”) continually reviews our NEO compensation elements and target opportunities against our peer group benchmarks. \n
	\n \n Annual incentive program\n \n			\n \n Moved to single a program called the Employee Incentive Program (“EIP”), which replaced Goals Results Incentive Program (“GRIP”) and broader-based Bonus Incentive Program (“BIP”), as further described in the “Components of our Compensation Program — Annual Cash Incentive Programs” section of this CD&A.\n \n \n In fiscal year 2026, the Company achieved record revenue and adjusted EBITDA. As a result, overall performance under the fiscal year 2026 EIP had an achievement level of 190% (above target). \n \n
	\n \n Long-term incentives\n \n			\n \n Maintained a performance focused equity mix of 60% performance stock units (“PSUs”) (at target) and 40% time-based restricted stock units (“RSUs”) in the long-term incentive program.\n \n \n Granted PSUs with a three-year performance period of July 1, 2025 through June 30, 2028, which awards are earned based on rTSR (100%) measured against S&P Composite 1500 — Electronic Equipment Instruments & Components Index. \n \n
	\n \n Fiscal year 2024 PSUs\n \n			\n Fiscal year 2024 PSUs were tied to performance against two equally weighted metrics (rTSR and Cash Flow from Operations). Strong shareholder returns resulted in a 200% achievement for the rTSR PSUs. The Cash Flow from Operations PSUs did not achieve the threshold performance level and resulted in zero percent payout, underscoring the program’s rigor. Each of the metrics is further described under “Components of our Compensation Program — Fiscal Year 2024-2026 PSU” section of this CD&A.\n

\n Fiscal Year 2025 Say-on-Pay Vote \n

\n The Committee reviewed the results of the fiscal year 2025 Say-on-Pay advisory vote as one of the many factors it considered. At our 2025 Annual Meeting of Shareholders, approximately 96% of the votes cast approved the compensation program described in the Company’s 2025 proxy statement. The Committee interpreted this level of support as affirmation of the design and objectives of our NEO compensation program. The Committee continues to monitor best practices among the Company’s peer group and industry standards related to executive compensation programs. \n

II. COMPENSATION PHILOSOPHY AND OBJECTIVES

\n \n \n \n \n \n \n \n \n \n \n \n \n \n

\n Pay-for-performance:\n
\n We aim to incentivize our executive officers by creating a strong link between their performance and compensation. We therefore base a significant portion of the total compensation packages we provide to our executive officers on measures that reflect both our short- and long-term goals and performance, as well as the executive officer’s individual performance and impact on shareholder value. \n

\n Alignment of executive officers’\n
\n interests with those of Coherent\n
\n and its shareholders:\n
\n Equity-based compensation\n
\n constitutes a significant portion of\n
\n our executive officers’ overall\n
\n compensation opportunity. The\n
\n Committee uses equity as the\n
\n form of long-term incentive\n
\n opportunities in order to\n
\n incentivize and reward executive\n
\n officers to (i) achieve multi-year\n
\n strategic goals and (ii) deliver\n
\n sustained long-term value\n
\n to shareholders. \n

\n Competitive compensation to\n
\n attract and retain talent:\n
\n To manage our business and\n
\n carry out our strategy, we seek\n
\n high-caliber executive officers\n
\n and managers who have broad range of experience, expertise,\n
\n capabilities and backgrounds.\n

\n In recruiting our executive officers\n
\n and determining competitive pay\n
\n levels, the Committee references\n
\n the amounts and compensation\n
\n structures of executive officers in\n
\n the companies in our\n
\n compensation peer group and in\n
\n industry surveys and utilizes the\n
\n services of an independent\n
\n compensation consultant.\n

III. COMPONENTS OF OUR COMPENSATION PROGRAM

FISCAL YEAR 2026 TARGET PAY MIX

\n The target pay mix supports the core principles of Coherent’s executive compensation philosophy of pay for performance and aligning executive officers’ interests with those of Coherent and its shareholders, by emphasizing both short- and long-term incentives. The Committee consistently aligns the executive officer total compensation with the Company’s strategic priorities to drive execution of our strategy. \n

\n The Committee selected the components of compensation set forth in the chart below to achieve Coherent’s executive compensation program objectives. The Committee regularly reviews all components of the program to verify that each executive officer’s total compensation is consistent with the compensation philosophy and objectives, and that each respective component is serving a purpose in supporting the execution of our strategy. The majority of each executive officer’s compensation is variable and at-risk, with a meaningful portion based on Coherent’s financial performance. \n

\n \n Base Salary \n \n	\n \n Fixed cash compensation.\n \n \n Determined based on each executive officer’s role, individual skills, experience, performance, and external market value. \n \n	\n Base salaries are intended to provide stable compensation to executive officers, enabling Coherent to attract and retain skilled executive talent and maintain a stable leadership team. \n
\n \n Short-Term Incentives: Annual Cash Incentive\n \n Opportunities \n \n	\n \n Employee Incentive Program (“EIP”) is a variable cash compensation program based on the level of achievement of pre-determined annual corporate goals.\n \n \n Cash incentive payouts range from zero for below-threshold performance to a maximum cap of 200% of each NEO’s target opportunity.\n \n \n To earn any payout, performance against the corporate objectives must exceed a threshold performance level. \n \n	\n Annual cash incentive opportunities are designed to ensure that executive officers are motivated to achieve Coherent’s annual goals; with payout levels determined based on actual financial results. \n
\n \n Long-Term Incentives: Annual Equity-Based Compensation\n \n	\n \n Variable equity-based compensation.\n \n \n PSUs: Performance share units with three-year cliff vesting. For fiscal year 2026 grants, the vesting is tied to relative TSR performance.\n \n \n RSUs: Restricted stock units with three-year ratable annual vesting tied to continued service through each annual vesting date. \n \n	\n Designed to motivate and reward executive officers to achieve multi-year strategic goals and to deliver sustained long-term value to shareholders, as well as to attract and retain executive officers.\n

BASE SALARY

\n Base salaries provide fixed compensation to Coherent’s executive officers and help to attract and retain the executive talent needed to lead the business and maintain a stable leadership team. Base salaries are individually determined according to each executive officer’s areas of responsibility, role and experience, and vary among executive officers based on a variety of considerations, including skills, experience, achievements, and the competitive market for the position. \n

\n 44 | COHERENT PROXY STATEMENT 2026

\n Table of Contents\n

\n From time to time, the Committee considers and approves base salary adjustments for executive officers. The main considerations for a salary adjustment are similar to those used in initially determining base salaries, but may also include change in the competitive market, change of role or responsibilities, recognition for achievements or market trends. \n

ANNUAL CASH INCENTIVE PROGRAMS

\n Beginning in fiscal year 2026, the Company implemented a single consolidated cash incentive program, the Employee Incentive Program (“EIP”), which replaced the Company’s prior GRIP and broader-based BIP. The Committee believes this streamlined structure provides a more consistent and transparent framework for aligning annual incentives with Company performance across the organization to foster a shared mindset and accountability for performance results. \n

\n The EIP is the annual cash-based incentive program that rewards our NEOs for the achievement of key short-term objectives. The structure of the annual cash program incentivizes NEOs to achieve annual financial results that the Committee views as critical to the execution of our business strategy, with the intent ultimately of increasing shareholder value. \n

\n In the Committee’s view, the most senior executive officers have the greatest responsibility for the performance of the Company, and consequently, the annual incentive opportunities for such executive officers utilize only pre-established objective Company performance measures, with no individual discretionary component. \n

\n For fiscal year 2026, the Committee, in consultation with its independent compensation consultant, approved a market-based adjustment to Mr. Anderson’s target annual cash incentive opportunity to maintain competitive market positioning relative to the revised 2026 Peer Group. Target annual cash incentive opportunities for the other NEOs, expressed as a percentage of base salary, remained unchanged from the prior year. \n

\n COHERENT PROXY STATEMENT 2026 | 45

\n Table of Contents\n

\n The Committee selected the following two financial measures, each weighted at 50% of the total EIP opportunity, because it believes that these metrics provide a balanced measure of Coherent’s ability to deliver growth, profitability and long-term shareholder value: \n

\n •\n
\n

\n \n Revenue (50%): The Committee selected Revenue to focus management on delivering profitable top line growth, a key strategic priority and leading indicator of the Company’s operating performance and long-term value creation. \n

\n •\n
\n

\n \n Adjusted EBITDA (50%): The Committee selected Adjusted EBITDA to incentivize operating profitability, generate the cash flow necessary to support continued investment in growth and reduce leverage, furthering our debt repayment strategy. \n

\n For the purposes of the EIP, “Revenue” is defined as the amount reported in our audited financial statements. “EBITDA” is defined as earnings before interest expense, interest income, income taxes, depreciation and amortization. Adjusted EBITDA excludes non-GAAP adjustments for share-based compensation, certain restructuring, integration, and transaction expenses, and the impact of foreign currency exchange gains and losses. Restructuring charges include severance, non-cash impairment charges for production assets and improvements on leased facilities, and other costs related to the restructuring plans. Integration, site consolidation and other costs include retention and severance payments, expenses not included in restructuring charges related to site closures as well as other integration costs related to the acquisition of Coherent, Inc. Start-up costs in operating expenses were related to the start-up of new devices for new customer applications. \n

\n Adjusted EBITDA is an adjusted non-GAAP financial measurement that is considered by management to be useful in measuring the profitability between companies within the industry by reflecting operating results of the Company excluding non-operating factors. There are limitations associated with the use of non-GAAP financial measures, including that such measures may not be entirely comparable to similarly titled measures used by other companies, due to potential differences among calculation methodologies. Thus, there can be no assurance whether (i) items excluded from the non-GAAP financial measures will occur in the future or (ii) there will be cash costs associated with items excluded from the non-GAAP financial measures. The Company compensates for these limitations by using these non-GAAP financial measures as supplements to GAAP financial measures and by providing the reconciliations of the non-GAAP financial measures to their most comparable GAAP financial measures. Investors should consider adjusted measures in addition to, and not as a substitute for, or superior to, financial performance measures prepared in accordance with GAAP. \n

\n For more information on the non-GAAP measures we use for our compensation performance metrics and how such non-GAAP measures are calculated, please see the earnings press release furnished with our Current Report on Form 8-K filed with the SEC on August 12, 2026. For a reconciliation of these non-GAAP measures to their most directly comparable financial measures calculated and presented in accordance with GAAP, please see the Appendix hereto. \n

THRESHOLD, TARGET AND MAXIMUM PERFORMANCE LEVELS

\n In the first quarter of fiscal year 2026, the Committee approved threshold, target and maximum performance levels for fiscal year 2026 based on the Company’s annual business plan. In setting these goals, the Committee took into account various factors, including forecasted growth levels for the global economy, for the geographic areas where the Company operates and for our product markets. The targets were designed to be challenging but achievable, requiring strong execution to deliver meaningful growth and profitability while appropriately reflecting the opportunities and risks incorporated in the Company’s business plan. \n

PAYOUT LEVELS

\n Payouts are determined based on actual performance relative to the pre-established goals, using payout curves approved by the Committee for the Revenue and the Adjusted EBITDA metrics, with payouts ranging from 0% for below-threshold performance to a maximum of 200% of target for performance at or above the maximum level. \n

LONG-TERM INCENTIVES

\n The third and largest component of the Coherent executive compensation program is long-term equity incentives. Long-term equity incentive awards are prospective in nature and intended to tie a substantial portion of an executive’s pay to creating long-term shareholder value. The Committee designed the long-term incentive opportunity to motivate and reward Coherent’s executive officers to achieve multi-year strategic goals and to deliver sustained long-term value to shareholders. The long-term incentives create a strong link between payouts and performance, and alignment between the interests of executive officers and the interests of Coherent’s shareholders. Long-term equity incentives also promote retention as executive officers will only receive value if they remain employed over the required term, and they foster an ownership culture among Coherent’s executive officers by making them shareholders with a personal stake in the value they create. \n

EQUITY VEHICLES AND MIX: PSUS AND RSUS

\n The Committee structured the mix of equity vehicles and the relative weight assigned to each type of award for the following reasons: 1) to motivate relative stock price outperformance over the long term through the PSUs, and 2) to ensure some amount of value delivery through the RSUs, which are complementary because they have upside potential but deliver some value even during periods of stock price underperformance, while also reinforcing an ownership culture and commitment to Coherent. \n

LONG TERM INCENTIVE OPPORTUNITIES

\n The Committee established fiscal year 2026’s long-term incentives for the NEOs in August 2025. In setting long-term incentive opportunities, the Committee considered the following: \n

\n •\n
\n

\n \n the values of, allocations to, and proportion of total compensation represented by, the long-term incentive opportunities at the peer group companies; \n

\n •\n
\n

\n \n individual performance and criticality of, and expected future contributions of the NEO; \n

\n •\n
\n

\n \n time in role, skills and experience; and \n

\n •\n
\n

\n \n retention considerations. \n

\n Table of Contents\n

FISCAL YEAR 2026 GRANTS OF PSUS AND RSUS

\n As described above, the Committee established the mix of equity vehicles for fiscal year 2026 as 60% PSUs / 40% RSUs for the NEOs. \n

\n To determine the target number of PSUs and RSUs, the approved target value for the long-term incentive opportunities as approved by the Committee is divided by the average closing stock price during the calendar month prior to the grant (July 2025). The resulting number of shares is then allocated between PSUs and RSUs based on the approved award mix. \n

\n The PSUs issued in fiscal year 2026 had a three-year performance period, beginning July 1, 2025 and ending June 30, 2028. The Committee approved relative Total Shareholder Return (TSR) as the performance metric for the fiscal year 2026-28 performance period, which measures Coherent’s TSR relative to companies in the S&P Composite 1500 — Electronic Equipment, Instruments & Components Index. \n

\n •\n
\n

\n \n By comparing Coherent’s performance to that of similar companies facing comparable conditions, the metric is designed to reward NEOs for delivering shareholder returns that equal or exceed industry peers. The Committee determined to use percentile rank as it aligns with the prevailing practice among our peer group and incentivizes successful execution of strategic initiatives to achieve relative outperformance. \n

\n •\n
\n

\n \n The Committee selected the S&P Composite 1500 — Electronic Equipment, Instruments & Components Index as the relevant index because it comprises a large set of comparable companies that are similar in size to Coherent. \n

\n The actual number of PSUs earned will be determined based on Coherent’s percentile rank relative to the TSRs of the companies in the index, as outlined in the table below. \n

\n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n

\n Performance Level \n	\n TSR Percent Rank \n	\n Earned Percentage \n
\n \n Below Threshold\n \n	\n Below 25th Percentile \n	\n \n 0% \n \n
\n \n Threshold\n \n	\n 25th Percentile \n	\n \n 50% \n \n
\n \n Target\n \n	\n 50th Percentile \n	\n \n 100% \n \n
\n \n Maximum\n \n	\n 75th Percentile and above \n	\n \n 200%\n \n

\n Linear interpolation will be used to determine payout levels if the actual performance falls between threshold and target performance levels and target and maximum. To achieve a threshold payout, TSR must rank at or above the 25th percentile. The number of PSUs earned is capped at 100% of target if Coherent’s absolute TSR is negative, regardless of relative performance. \n

\n The Committee views the use of the TSR metric as appropriate, as it directly links executive compensation to shareholder value creation and aligns the interests of executive officers with those of Coherent and its shareholders. It also ensures that PSUs are more closely tied to performance across varying economic cycles. \n

\n The PSUs cliff vest at the end of the three-year performance period, without interim vesting opportunities. The RSUs vest one-third (1/3) on the first anniversary of the grant date with the remainder vesting ratably over the following eight quarters. \n

\n \n Represents the amounts approved and intended by the Committee, which differ from the grant date fair value reflected in the summary compensation table. The grant date fair value reflected in the summary compensation table is based on the thirty-day trailing average closing price for RSUs and a Monte Carlo simulation calculated in accordance with FASB ASC Topic 718 for PSUs. \n

\n Special Performance-Based Retention Award for Dr. Eng \n

\n In August 2025, the Committee approved a one-time special retention award for Dr. Eng, with a grant-date fair value of $5.0 million. The award consists entirely of performance-based stock units that can be earned in August 2028, subject to achievement of the applicable performance objectives and Dr. Eng’s continued employment through the vesting date. The award was designed to reinforce Dr. Eng’s continued leadership of critical technology initiatives and commercialization priorities as Coherent continues to develop and commercialize key products in its technology portfolio. Fifty percent of the award is tied to the public demonstration of specific products by the end of calendar 2026, with the remaining 50% tied to the commercialization of the same products by the end of calendar 2027. The rigorous, time-bound objectives directly support Coherent’s technology roadmap and commercialization priorities. \n

\n In approving the award, the Committee considered Dr. Eng’s critical role in advancing Coherent’s technology roadmap, and the importance of retaining her leadership through the pivotal milestones. The Committee also considered the strong external demand and career opportunities available for proven technology leaders with expertise in AI infrastructure and optical networking. The Committee determined that this targeted, performance-based retention opportunity was reasonable, appropriately supporting leadership continuity and aligning Dr. Eng’s interests with the achievement of these critical technical and commercial milestones. \n

FISCAL YEAR 2024-2026 PSUs

\n In fiscal year 2024, the Committee granted PSUs with performance-based vesting requirements for the three-year performance period encompassing fiscal years 2024-2026. The fiscal year 2024 PSUs were based on two performance metrics; fifty percent (50%) based on cumulative Relative TSR and fifty percent (50%) based on cash flow from operations. The comparator group for the Relative TSR PSUs was the S&P Composite 1500 — Electronic Equipment, Instruments & Components (Industry) Index. Cash flow from Operations was measured as reported in the Company’s financial statements for the three-year performance period. \n

IV. COMPENSATION DETERMINATION PROCESS AND GOVERNANCE

\n Coherent assesses the effectiveness of the executive compensation program on an ongoing basis and reviews risk mitigation and governance matters, which includes the following best practices: \n

What We Do

	\n \n $\"[MISSING$ \n \n \n \n Pay for Performance\n \n \n			\n \n The majority of total target compensation opportunity for our NEOs is variable and at-risk. \n \n
	\n \n $\"[MISSING$ \n \n \n \n Balance Short- and Long-Term Compensation\n \n \n \n \n			\n \n The allocation of incentives among the annual incentive programs and the long-term incentive plan does not over-emphasize short-term performance at the expense of achieving long-term goals. \n \n
	\n \n $\"[MISSING$ \n \n \n \n Combination of Balanced Performance Metrics\n \n \n \n \n			\n \n We use differentiated financial performance metrics in our annual incentive programs for executive officers. \n \n

	\n No Repricing of Underwater\n \n Stock Options \n			\n \n Our equity plan does not permit the repricing of stock options where the strike price exceeds the then-current fair market value without shareholder approval. \n \n
	\n No Hedging or Pledging of Company Securities \n			\n \n We prohibit executive officers and non-employee directors from engaging in hedging, pledging or short sale transactions in Company securities. \n \n

ROLE OF THE COMMITTEE

\n The Committee establishes the compensation philosophy and objectives, determines the structure, components and other elements of executive compensation, and reviews the compensation of the NEOs and recommends it for approval by the Board of Directors. \n

\n The Committee structures the executive compensation program to accomplish articulated compensation objectives in light of the compensation philosophy described above. \n

\n In accordance with its charter, the Committee establishes total compensation for the CEO (generally at the beginning of the fiscal year). The Committee reviews and evaluates the performance of the CEO and develops base salary and incentive compensation recommendations for the Board to consider. The CEO did not play any role with respect to any matter affecting his own compensation and was not present when the Committee discussed and formulated its recommendation for his compensation. \n

\n With the input of the CEO, the Committee also established the compensation for all the other executive officers. As part of this process, the CEO evaluated the performance of the other executive officers and made recommendations to the Committee regarding the compensation of each executive officer. The Committee gave significant weight to the CEO’s recommendations considering his greater familiarity with the day-to-day performance of his direct reports and the importance of incentive compensation in driving the execution of managerial initiatives developed and led by Mr. Anderson. Nevertheless, the Committee and the Board made the ultimate determinations regarding the compensation for the executive officers. \n

\n Pursuant to its charter, the Committee is permitted to delegate its authority to the CEO to make certain equity grants to employees who are not Section 16 officers, its administrative duties with respect to certain retirement plans and the development of agendas and minutes. \n

ROLE OF THE INDEPENDENT COMPENSATION CONSULTANT

\n The Committee recognizes the importance of obtaining objective, independent expertise and advice in carrying out its responsibilities. The Committee has the power to retain an independent compensation consultant to assist in the performance of its duties and responsibilities. \n

\n The Committee has retained the services of Compensia, Inc. (“Compensia”) as its independent compensation consultant since June 2025. Compensia reports directly to the Committee, and the Committee had the sole authority to retain, terminate \n

\n 54 | COHERENT PROXY STATEMENT 2026

\n Table of Contents\n

\n and obtain the advice of independent advisors at Coherent’s expense. Representatives of Compensia, as applicable, met informally with the Chair of the Committee and formally with the full Committee during its regularly scheduled meetings, including in executive sessions without management present from time to time. \n

\n In fiscal 2026, the Committee worked with Compensia to provide a competitive market analysis of the base salary, annual cash incentive awards and long-term incentive compensation of our executive officers compared against the compensation peer group, report on share utilization, assess compensation risk and review other market practices and trends and regulatory developments. While the Committee took into consideration the review and recommendations of Compensia when making decisions about the executive compensation program, ultimately, the Committee made its own independent decisions about compensation matters. \n

\n The Committee assessed the independence of Compensia pursuant to SEC and NYSE rules. In doing so, the Committee considered each of the factors set forth by the SEC and the NYSE with respect to a compensation consultant’s independence, including the fact that neither consultant provided other services to the Company. The Committee also considered the nature and amount of work performed for the Committee and the fees paid for those services in relation to each firm’s total revenues. Based on its consideration of the foregoing and other relevant factors, the Committee concluded that there were no conflicts of interest, and that Compensia is independent. \n

EXECUTIVE COMPENSATION COMPETITIVE MARKET INFORMATION

\n Each year, the Committee reassesses the group of peer companies used as a reference point for evaluating executive compensation to ensure its continued appropriateness. \n

\n In making determinations about executive compensation, the Committee believes that obtaining relevant market data is important, because it serves as a reference point for making decisions and provides helpful context. When making decisions about the structure and component mix of the executive compensation program, the Committee considers the structure and components of, and the amounts paid under, the executive compensation programs of other comparable peer companies, as derived from public filings and other sources. \n

\n The Committee, with the assistance of Compensia, developed a peer group in the second half of fiscal year 2025. The criteria used to determine the peer group generally included: companies in the electronic components sector; revenue in the range of approximately 1/3 to 3 times Coherent’s revenue; and market capitalization in the range of 1/4 to 4 times Coherent’s market capitalization. \n

\n Based on these criteria and considerations, the peer group that was used to inform fiscal year 2026 executive compensation decisions, as approved by the Committee, consisted of the following 20 companies: \n

Fiscal Year 2026 Peer Group

\n Akamai Technologies (AKAM) \n	\n KLA Corporation (KLAC) \n	\n Qorvo, Inc. (QRVO) \n
\n Arista Networks, Inc. (ANET) \n	\n Lumentum Holdings, Inc. (LITE) \n	\n Skyworks Solutions, Inc. (SWKS) \n
\n Ciena Corporation (CIEN) \n	\n Marvell Technology (MRVL) \n	\n Teradyne (TER) \n
\n Corning Incorporated (GLW) \n	\n MKS Instruments, Inc. (MKSI) \n	\n Trimble Inc. (TRMB) \n
\n Entegris, Inc. (ENTG) \n	\n NetApp (NTAP) \n	\n Twilio (TWLO) \n
\n F5 (FFIV) \n	\n \n ON Semiconductor Corporation (ON) \n \n	\n Zebra Technologies Corporation (ZBRA) \n
\n Keysight Technologies, Inc. (KEYS) \n	\n Pure Storage (P) \n

\n Based on the financial data as of June 30, 2025 used in the peer group review, Coherent ranked at the 72nd percentile for revenue and the 23rd percentile for 30-day market capitalization among the peer group. \n

\n COHERENT PROXY STATEMENT 2026 | 55

\n Table of Contents\n

\n The Committee believes that the peer group’s compensation practices provide appropriate compensation reference points for determining the fiscal year 2026 compensation for Coherent’s NEOs. Consistent with best practices for corporate governance, the Committee intends to review the peer group annually. \n

V. ADDITIONAL COMPENSATION POLICIES AND PRACTICES

\n We generally provide our NEOs the same benefits we provide to all employees, including certain health and welfare benefits and a 401(k) retirement savings plan. In addition, we provide our NEOs with certain additional benefits intended to be competitive with the practices of companies in our peer group. \n

\n 401(k) Plan. The Company maintains the Coherent Corp. 401(k) Profit Sharing Plan (the “401(k) Plan”), which covers substantially all U.S. employees of the Company, including the NEOs. The 401(k) Plan is a voluntary contributory plan under which employees may elect to defer compensation. The Company makes matching contributions up to 4% of the employee’s individual earnings, subject to limitations under federal tax rules. Additionally, the Company may make discretionary profit-sharing contributions for employees under the 401(k) Plan, and the Company made such contributions to certain employees for the most recent fiscal year. Company contributions to NEO accounts under the 401(k) Plan are set forth in the “All Other Compensation” column of the Summary Compensation Table. \n

\n Deferred Compensation. The Coherent Corp. Nonqualified Deferred Compensation Plan (the “Deferred Compensation Plan”) is designed to allow executive officers and certain other employees of the Company to defer receipt of compensation for retirement or other qualified purposes. The Deferred Compensation Plan provides the NEOs the opportunity to defer compensation when they are not able to take full advantage of the 401(k) Plan because of tax rules limiting contributions. In addition, the Company makes matching contributions under the Deferred Compensation Plan to make up for the limitations on matching contributions under the 401(k) Plan that are imposed by tax rules. For a description of the Deferred Compensation Plan and more information regarding the amounts deferred under the Deferred Compensation Plan, see the “Nonqualified Deferred Compensation for Fiscal Year 2026” section of this proxy statement. \n

\n Severance and Change in Control. To enable us to offer competitive total compensation packages to our senior leaders, including our executive officers, as well as to promote their ongoing retention when considering potential transactions that may create uncertainty as to their future employment with us, we offer certain post-employment payments and benefits to such employees, including the NEOs, upon the occurrence of specified events, including upon involuntary termination and upon certain terminations in connection with a change in control of the Company. \n

\n Executive Severance Plan. The Executive Severance Plan provides severance benefits upon a qualifying termination of employment to selected employees of the Company. The Executive Severance Plan also contains certain non-duplication provisions such that the severance payments and benefits under the Executive Severance Plan are offset or reduced by any severance payments and benefits that otherwise would be received by an executive under the terms of any other agreement, policy, or plan maintained by the Company that provides for severance benefits. For fiscal year 2027, participation agreements for our NEO’s (other than our CEO) have been updated after consultation with the Committee’s independent compensation consultant, to provide severance benefits more aligned with market severance provisions. A summary description of the Executive Severance Plan is included in the “Potential Payments Upon Termination and/or Change in Control” section of this proxy statement. \n

\n Change in Control. The Committee believes that the long-term interests of Coherent shareholders are best served by providing reasonable income protection, equity acceleration and other severance benefits for senior leaders, including our NEOs, to address potential change in control situations in which they may otherwise be distracted by their potential loss of employment in the event of a successful transaction. These are “double trigger” arrangements — i.e., severance benefits under these arrangements are only triggered by a qualifying event that also resulted in the executive’s termination of employment under certain specified circumstances within three months before through two years following the event. The Company does not provide tax gross-ups on any excise taxes that may be triggered by change in control payments. \n

\n 56 | COHERENT PROXY STATEMENT 2026

\n Table of Contents\n

\n For additional information on payments on termination of employment or change in control, please refer to the “Potential Payments Upon Termination and/or Change in Control” section of this proxy statement. \n

\n Employment Agreements. Mr. Anderson has an offer letter that provides for severance benefits. A summary description of Mr. Anderson’s severance benefits is included in the “Potential Payments upon Change in Control and Employment Termination” section of this proxy statement. \n

\n Health and Welfare Benefits. Coherent offers broad-based medical, dental, vision, life, and disability plans to all employees. \n

\n Perquisites and Other Personal Benefits. The Company provides limited perquisites or personal benefits to its NEOs. The perquisites and personal benefits summarized above were provided because Coherent believed that they supported executive officers, served a necessary business purpose, and the related amounts of compensation were not material to the overall executive compensation program. The costs of these items are reported in the Summary Compensation Table. \n

\n Employee Stock Purchase Plan. Pursuant to our employee stock purchase plan, our employees, including each of our NEOs, have an opportunity to purchase our common stock at a discount on a tax-qualified basis through payroll deductions. The employee stock purchase plan is designed to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. The purpose of the employee stock purchase plan is to encourage our employees, including our named executive officers, to become our shareholders and better align their interests with those of our other shareholders. \n

CLAWBACK POLICY

\n In accordance with Section 10D of the Securities Exchange Act of 1934, Rule 10D-1 promulgated thereunder, and the listing standards of the New York Stock Exchange, the Company adopted a Compensation Recovery (“Clawback”) Policy to comply with the same as of October 2, 2023 (the “Clawback Policy”). The Clawback Policy requires the Company to recover from covered executive officers the amount of erroneously awarded compensation resulting from an accounting restatement due to the material noncompliance of the Company with any financial reporting requirement under the securities laws. The Clawback Policy supersedes and replaces the Company’s prior compensation recovery policy for incentive-based compensation received from and after October 2, 2023. Under that prior policy, which still applies to incentive-based compensation received before October 2, 2023, if the Company must restate its financial statements due to material non-compliance with any financial reporting requirements, any current or former executive officer or other employee of the Company (i) who received incentive compensation based on financial information that is subject to restatement, and (ii) whose gross negligence, fraud or misconduct caused or contributed to the non-compliance resulting in the restatement, would be required to reimburse the Company for any incentive compensation received in excess of what they would have received under the restatement. In addition, if the Board in its sole judgment determines that the gross negligence, fraud or misconduct by a current or former executive officer or other employee caused or contributed to the need for the restatement, then under the prior policy such person would be required to repay the net profits realized from any sales of shares of Common Stock that were received as incentive compensation based on the restated financial statements. \n

EXECUTIVE STOCK OWNERSHIP GUIDELINES

\n The Committee believes that Coherent and its shareholders are best served when executive officers manage the business with a long-term perspective. As such, Coherent has implemented executive stock ownership guidelines, as Coherent believes stock ownership is an important tool to strengthen the alignment of interests among executive officers and shareholders, to reinforce executive officers’ commitment to Coherent and to demonstrate Coherent’s commitment to sound corporate governance. For purposes of the guidelines, stock held and time-based RSUs count; unexercised options, vested and unvested options and unearned performance-based shares or units do not count. This policy requires our CEO to own Common Stock and RSUs having an aggregate value of at least three times his annual base salary, and our other executive officers to own Common Stock and RSUs having an aggregate value at least equal to their annual base salary. The guidelines have a phase-in period to allow newly hired or promoted executives to acquire the requisite share levels over a period of three years. All of our current NEOs are in compliance with our stock ownership guidelines or fall within the period to attain the guideline level of stock ownership. \n

ANTI-HEDGING AND ANTI-PLEDGING POLICY

\n To further demonstrate the Company’s commitment to align the interests of our officers and directors with those of our shareholders, the Board has adopted a policy which prohibits hedging or pledging of Company stock by members of our Board and executive officers, including a prohibition on holding shares in a margin account. \n

RISKS IN COMPENSATION PROGRAMS AND PRACTICES

\n The Committee periodically reviews our compensation policies and practices to ensure that they do not encourage our executives or other employees to take excessive risks or emphasize short-term results at the expense of long-term shareholder value. Based on its review, the Committee believes that risks arising from our compensation policies and practices are not reasonably likely to have a material adverse effect on the Company. \n

TIMING OF EQUITY AWARDS

Grants of equity awards to our executive officers are generally determined and approved at our pre-scheduled quarterly Committee meetings whenever practicable, and the awards are granted in accordance with our equity grant policies and processes. In addition, the Committee approves the annual equity refresh grants, including performance-based awards, in the first quarter of each year. However, the Committee may otherwise approve the grant of equity awards outside of a pre-scheduled meeting in connection with a new hire, promotion, and other circumstances where the Committee deems it appropriate to make such grants.

TAX CONSIDERATIONS: SECTION 162(M)

\n Section 162(m) of the Code generally provides that publicly held companies may not deduct compensation paid to certain of their top executive officers to the extent that such compensation exceeds $1 million per officer in any given year. While the Committee considers the deductibility of awards as one factor in determining executive compensation, the Committee also looks at other factors in making its decisions and retains the flexibility to award compensation that it determines to be consistent with the goals of our executive compensation program even if the compensation is not deductible by us for tax purposes. \n

ACCOUNTING FOR STOCK-BASED COMPENSATION

\n We follow Financial Accounting Standards Board ASC Topic 718 for our stock-based compensation awards. In accordance with ASC Topic 718, stock-based compensation cost is measured at the grant date, or with respect to performance-based awards, the service inception date, based on the estimated fair value of the awards using a variety of assumptions. This calculation is performed for accounting purposes and, as applicable, reported in the compensation tables, even though recipients may never realize any value from their awards. We record this expense on an ongoing basis over the requisite employee service period. Accounting rules also require us to record cash compensation as an expense at the time the obligation is incurred. \n

\n As disclosed in the Company’s Form 8-K, filed on August 31, 2026, the Committee approved special incentive awards for key members of Coherent’s leadership team, including James R. Anderson, Chief Executive Officer; Sherri Luther, Chief Financial Officer; Julie Eng, Chief Technology Officer and Executive Vice President, Optical Components; Rob Beard, Chief Strategy and Legal Affairs Officer; and Jeffrey Place, Chief Supply Chain Officer. These awards consist entirely of PSUs, with vesting tied to the achievement of significant share price growth milestones, satisfaction of a relative total shareholder return hurdle and a continued service requirement through 2030. The Awards were granted pursuant to and under the Coherent Corp. Omnibus Incentive Plan, as amended and restated. \n

\n The grant date fair value of the fiscal year 2027 PSUs and full details of the incentive program will be reflected in our 2027 proxy statement, including fiscal year 2027 Summary Compensation Table and in the Grants of Plan-Based Awards Table for our 2027 annual meeting of shareholders. \n

\n \n Represents the aggregate grant date fair value of RSUs, and PSUs awarded by the Company during the fiscal years presented, computed in accordance with FASB ASC Topic 718 (excluding the effect of estimated forfeitures). The assumptions used by the Company in calculating these amounts are incorporated herein by reference to Note 13 to the Company’s Consolidated Financial Statements included in its Annual Report on Form 10-K for the fiscal year that ended on June 30, 2026. For RSUs, the grant date fair value was computed based on the closing price of the Common Stock on the date of grant, multiplied by the number of shares awarded. \n

\n 2.\n
\n

\n \n The grant date fair value of the PSU awards included in this column was calculated based on the estimate of aggregate compensation expense to be recognized over the service period, excluding the effect of estimated forfeitures. For the fiscal year 2026 PSUs, which have a single rTSR metric, this was calculated based on a Monte Carlo simulation fair value as of the grant date. This amount was $139.89 per share for the awards granted to the NEOs on August 28, 2025 and $169.21 per share for the award granted to James Anderson on August 28, 2025. Please refer to the “Compensation Discussion and Analysis” section of this proxy statement for the target value approved by the Committee. \n

\n

\n \n Amounts reflect the cash awards earned by our NEOs under our annual cash incentive program, EIP, which is discussed in further detail in the “Compensation Discussion and Analysis” section of this proxy statement. \n

The Company contributions are matching contributions earned in fiscal year 2026 for the 2025 calendar year. \n

\n \n These columns show the range of potential payouts for awards made to our NEOs in fiscal year 2026 under our annual cash incentive program, EIP, assuming the target or maximum goals are satisfied with respect to the applicable performance measures underlying the awards. The business measurements and performance goals underlying these awards are described in the “Compensation Discussion and Analysis” section of this proxy statement. The aggregate amounts actually paid to our NEOs under these plans for fiscal year 2026 are set forth in the Summary Compensation Table in the column titled “Non-Equity Incentive Plan Compensation.” Additional details regarding the specific pay-outs under each of the plans are provided in the footnotes. \n

\n \n Amounts in this column represent certain matching contributions made under the Deferred Compensation Plan for fiscal year 2026 to make up for IRS limitations on matching contributions under the 401(k) Retirement Savings Plan for calendar year 2026. These amounts were included as fiscal year 2026 compensation under “All Other Compensation” in the Summary Compensation Table. \n

\n 2.\n
\n

\n \n Aggregate earnings include all changes in value based on performance of deemed investments elected by the NEO under the Deferred Compensation Plan. The Deferred Compensation Plan is administered by a third party and provides for deemed investment options similar to the investment options available under the Company’s 401(k) Retirement Savings Plan, with the exception that amounts under the Deferred Compensation Plan may be invested in Common Stock. Amounts that are deferred into Common Stock must remain invested in Common Stock and must be paid out in shares of Common Stock upon a qualifying distribution event. \n

\n The Deferred Compensation Plan was established to provide retirement savings benefits for NEOs and certain other employees beyond what is available through the 401(k) Retirement Savings Plan, which is subject to IRS limitations on annual contributions and compensation. Under the Deferred Compensation Plan, eligible participants can elect to defer up to 100% of certain performance-based cash incentive compensation and certain equity awards into an account that will be credited with earnings at the same rate as one or more deemed investments chosen by the participant. The Company may make matching contributions and other Company contributions to the Deferred Compensation Plan. A participant’s right to receive benefits under the Deferred Compensation Plan is an unfunded, unsecured right, no greater than the claim of a general creditor of the Company. Any assets that the Company sets aside to pay benefits under the Deferred Compensation Plan are the property of the Company and subject to claims of the Company’s creditors in case of the Company’s insolvency. Participants are eligible to receive distributions from the Deferred Compensation Plan upon a separation from service (as defined in the Deferred Compensation Plan) and may also receive in-service distributions in certain circumstances. They may also elect to receive payments in a lump sum or in annual installments over a specified term of years. \n

POTENTIAL PAYMENTS UPON TERMINATION AND/OR CHANGE IN CONTROL

\n Each of our NEOs is eligible to receive potential benefits and/or payments upon termination of employment and/or change in control. \n

TREATMENT OF EQUITY AWARDS

\n The equity award agreements for the NEOs’ outstanding, unvested equity awards — currently comprised only of restricted stock units (“RSUs”) and performance share units (“PSUs”) — include the following vesting treatment upon termination of employment, subject to more favorable treatment under individual agreements or severance plans as described below: \n

\n •\n
\n

\n \n Death or Disability: If a NEO dies or becomes disabled, such NEO’s (i) RSUs immediately vest, and (ii) PSUs will generally be prorated, based on the months employed during the performance period, subject to actual performance results for the full performance period. \n

\n •\n
\n

\n \n Termination without Cause or with Good Reason (Non-Change in Control): If a NEO is terminated by the Company without Cause or by the NEO for Good Reason (other than during the two-year period following a Change in Control), RSUs and PSUs with a vesting date within twelve months of the date of termination will fully vest. In addition, any RSUs and PSUs with a vesting tranche during the twelve months following the date of termination will be prorated, based on the number of months employed during the performance or vesting period, subject to actual performance results for the full performance period (in the case of PSUs). \n

\n •\n
\n

\n \n Change in Control (Double-Trigger): If the Company has a Change in Control and the resulting entity assumes, converts or replaces outstanding Company equity awards upon the Change in Control, the equity awards will not accelerate and vest unless, within two years of the date of the Change in Control, the NEO’s employment is terminated by the Company without Cause or by the NEO for Good Reason, in which cases unvested awards will fully vest upon such termination of employment. Vesting of PSUs in each case will be based on the greater of (x) an assumed achievement of all relevant performance goals at the “target level” and (y) the actual level of achievement of all relevant performance goals against target as of the Company’s fiscal quarter end preceding the Change in Control. Because vesting requires the occurrence of two events, a Change in Control followed by an involuntary employment termination (as described in this paragraph), this vesting treatment is often referred to as a “double trigger” vesting. If, however, the Company has a Change in Control and the resulting entity does not assume, convert or replace the equity awards, the NEO’s outstanding equity awards will fully vest upon the Change in Control, based on the same assumed performance for PSUs (i.e., greater of target or actual performance). \n

\n •\n
\n

\n \n All Other Terminations: Unvested RSUs and PSUs immediately forfeit upon any other termination of employment, except as may otherwise be provided in individual agreements or severance plans or as determined by the Compensation and Human Capital Committee in its discretion. \n

\n In addition to these standard award agreement vesting terms, special equity vesting terms apply to Mr. Anderson under his May 31, 2024 offer letter (the “Offer Letter”) and to the other NEOs under their Participation Agreements entered under the Company’s Revised Executive Severance Plan (the “Executive Severance Plan”). Under Mr. Anderson’s Offer Letter and the Participation Agreements under the Executive Severance Plan, if an executive’s employment is terminated by the Company without Cause or by the executive for Good Reason, outstanding equity awards will receive additional vesting based on whether the termination occurs during a CIC Period (defined as the period beginning 6 months before and ending 18 months after a Change in Control), as follows: \n

\n •\n
\n

\n \n Termination Not During a CIC Period: All outstanding, unvested equity awards with a vesting date within 12 months after the date of termination will fully vest and, if applicable, will remain exercisable for the period set forth in the applicable award agreement. In addition, any vesting tranche of such equity awards that began during employment or during the first 12 months after the date of termination but was not completed by the first anniversary of the date of termination, will \n

\n 68 | COHERENT PROXY STATEMENT 2026

\n Table of Contents\n

\n vest on a pro-rata basis. The payout for any PSUs will be based on actual performance during the entire performance period and then pro-rated (taking into account the additional 12 months following termination), except that for inducement PSUs under Mr. Anderson’s Offer Letter, performance will be determined on the date of termination and the payout will be the greater of target or actual performance. \n

\n •\n
\n

\n \n Termination During a CIC Period: If the termination occurs during a CIC Period, all outstanding, unvested equity awards will become fully vested and, if applicable, will remain exercisable for the period set forth in the applicable award agreement. In the case of any PSUs, vesting will be based on the greater of (i) an assumed achievement of all relevant performance goals at the “target level” and (ii) the actual level of achievement of all relevant performance goals against target measured for the period from the beginning of the relevant performance period through, for Mr. Anderson, the date immediately preceding the Change in Control, and for other NEO’s, the Company’s fiscal quarter end immediately preceding the Change in Control. \n

\n Receipt of additional equity vesting under Mr. Anderson’s Offer Letter and under the Participation Agreements under the Executive Severance Plan are subject to certain conditions, including that the executive provide the Company with a release of claims and comply with applicable post-employment covenants, which include protection of confidential Company information, assignment of inventions, non-competition, and non-solicitation of customers and employees. \n

\n The following table sets forth the value of each NEO’s accelerated RSUs and PSUs in the event of a termination of employment and/or Change in Control, as if such termination of employment and/or Change in Control had occurred on June 30, 2026, the last day of our fiscal year 2026. The value of the equity awards are based on the closing market price of our Common Stock on June 30, 2026, the last trading day of the fiscal year, which was $394.47 per share. \n

\n

\n \n Assumes that all equity awards are assumed, converted and/or replaced by the resulting entity, that there is no accelerated vesting pursuant to the terms of the applicable award agreements if such NEO’s employment continues after a Change in Control and that such NEO is not terminated without Cause, or by the NEO for Good Reason, within two years of such Change in Control. \n

\n 4.\n
\n

\n \n Assumes that no equity award is assumed, converted and/or replaced by the resulting entity. Pursuant to the terms of the applicable equity plans, any stock options become fully exercisable, any unvested portions of any RSUs fully vest and any unvested portions of any PSUs are deemed fully earned as of the date of the Change in Control. For purposes of calculating the value of the accelerated PSUs, we have assumed achievement of all relevant performance goals at the “target level.” \n

SEVERANCE PAYMENTS

\n In addition to equity vesting, the NEOs may become eligible for additional severance payments in case of a qualifying termination, generally defined as (i) a termination of employment by the Company other than for Cause, death or disability, or (ii) the NEO’s resignation for Good Reason. The right to severance payments upon a qualifying termination is governed by the Offer Letter for Mr. Anderson and the applicable Participation Agreements under the Executive Severance Plan for the other NEOs. The following discussion summarizes and quantifies those severance payments. \n

\n Mr. Anderson’s Offer Letter and the Executive Severance Plan include definitions of “Cause” and “Good Reason,” which are generally similar to one another but with minor variations. These definitions also control for purposes of equity vesting noted in the preceding section. “Cause” generally requires conduct significantly adverse to the Company, such as material breach by the executive of agreements, willful failure to perform duties, willful violation of Company policies, conviction of certain crimes, and other types of significant misconduct, and “Good Reason” is generally triggered by the Company reducing pay, reducing duties and responsibilities, requiring significant additional business travel, or forcing a significant home relocation, all subject to certain notice and cure requirements. The definition of “Change in Control” is also generally similar in each agreement, and as general matter requires a change in majority ownership of the Company or sale of all or majority of the Company’s assets. The specific definitions can be found in the Offer Letter and Executive Severance Plan, as publicly filed with our Annual Report on Form 10-K. \n

\n In each case, the amount and type of severance payments vary based on whether the qualifying termination occurs during a CIC Period, defined as the period beginning 6 months before and ending 18 months after a Change in Control. \n

\n COHERENT PROXY STATEMENT 2026 | 71

\n Table of Contents\n

\n In each case, payments received in connection with a Change in Control can potentially trigger excise taxes under Sections 280G and 4999 of the Code. The relevant agreements and Executive Severance Plan do not provide gross-up payments for these excise taxes. Instead, payments are required to be scaled back to an amount that would reduce the excise taxes, if such reduction would result in the NEO retaining a larger amount on an after-tax basis. \n

\n Payments under the Offer Letter and the Executive Severance Plan are conditioned on the NEO providing the Company with a release of claims and complying with applicable post-employment covenants, which include protection of confidential Company information, assignment of inventions, non-competition, and non-solicitation of customers and employees. \n

OFFER LETTER — JAMES R. ANDERSON

\n Mr. Anderson’s Offer Letter sets forth the terms and conditions of his severance benefits (in addition to the equity vesting described in the preceding section), depending on whether the qualifying termination occurs during a CIC Period, summarized as follows: \n

\n •\n
\n

\n \n Qualifying Termination Not During a CIC Period. If Mr. Anderson’s employment is terminated by the Company without Cause, or by Mr. Anderson for Good Reason, and such termination is not during a CIC Period, after providing the Company with a release, the Company will pay Mr. Anderson cash severance in an amount equal to 24 times his then current monthly salary plus any bonus that Mr. Anderson would have earned had his employment continued through the end of the fiscal year in which his employment was terminated. The Company will also pay the premiums for health insurance coverage for a period of 24 months. These payments will be made in a cash lump shortly after the date of termination. \n

\n •\n
\n

\n \n Qualifying Termination During a CIC Period. If Mr. Anderson’s employment is terminated by the Company without Cause, or by Mr. Anderson for Good Reason, and such termination occurs during a CIC Period, after providing the Company with a release, the Company will pay Mr. Anderson cash severance in an amount equal to 36 times his then current monthly salary plus three times the amount of the target bonus for the fiscal year in which his employment was terminated. The Company will also pay the premiums for health insurance coverage for a period of 36 months. Finally, the Company will pay to Mr. Anderson an amount equal to a pro-rata portion of his “CIC Period Bonus” (defined generally as the greater of his target or actual annual incentive award for the year of termination or the year in which the Change in Control occurred) plus any annual incentive award owed to Mr. Anderson for the year preceding Mr. Anderson’s termination. These payments will be made in a cash lump sum shortly after the date of termination, provided that special rules apply if Mr. Anderson’s termination occurs during the portion of the CIC Period preceding the Change in Control. \n

\n The following tables summarize the estimated severance payments that Mr. Anderson would have been entitled to receive assuming that a termination of his employment occurred as of June 30, 2026. \n

PARTICIPATION AGREEMENTS/EXECUTIVE SEVERANCE PLAN

\n The Executive Severance Plan covers select members of management who are offered coverage and execute a Participation Agreement, which includes each of the NEOs other than Mr. Anderson. Under the terms of the Executive Severance Plan and applicable Participation Agreements, the amount of severance (in addition to the equity vesting described in the preceding section) depends on whether the qualifying termination occurs during a CIC Period, summarized as follows: \n

\n •\n
\n

\n \n Qualifying Termination Not During a CIC Period. If a participant’s employment is terminated by the Company without Cause, or by the participant for Good Reason, and such termination is not during a CIC Period, after providing the Company with a release, the Company will pay the participant an amount equal to (i) 12 months of then-current annual base salary, and (ii) the participant’s target bonus and prorated based on the portion of the year completed prior to the date of termination. The Company will also pay the participant lump sum cash payment equal to the cost of the participant’s health care insurance premiums for a period of 12 months. \n

CEO PAY RATIO

\n Information about the relationship between Jim Anderson’s fiscal year 2026 annual total compensation, and the median annual total compensation of our employees is provided below. \n

\n Mr. Anderson’s fiscal year 2026 annual total compensation was $28,349,672 as reported in the Summary Compensation Table and the annual total compensation of our median compensated employee, also referred to as our median employee, was $20,527, and the ratio of these amounts is 1 to 1,381. \n

\n We took the steps below to calculate the annual total compensation of James Anderson and determine the annual total compensation of our median compensated employee. \n

\n 1.\n
\n

\n \n To determine the annual total compensation of Mr. Anderson, we used the amount reported in the “Total” column of our fiscal year 2026 Summary Compensation Table included in this proxy statement. \n

\n 2.\n
\n

\n \n To determine our median compensated employee, we determined that, as of June 30, 2026, our employee population consisted of approximately 47,620 individuals and excluded James Anderson. This population consisted of our full-time, part-time, and temporary employees as of the determination date. \n

\n 3.\n
\n

\n \n To identify the “median employee” from our employee population we used base salary, as reflected in our payroll records, for fiscal year 2026 . For base salary, we generally used the total amount of compensation the employees were paid before any taxes, deductions, insurance premiums, and other payroll withholding. We did not use any statistical sampling techniques. \n

\n 4.\n
\n

\n \n To determine the annual total compensation of our median employee, we then identified and calculated the elements of that employee’s compensation for fiscal year 2026 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $20,527. \n

\n 5.\n
\n

\n \n For currency conversion, the prevailing rates as of June 30, 2026 were used to reflect base salary in U.S. dollars and for all other purposes. \n

\n The CEO pay ratio reported above is a reasonable estimate, calculated in a manner consistent with SEC rules, based on the methodologies and assumptions described above. SEC rules for identifying the median employee and determining the CEO pay ratio permit companies to employ a wide range of methodologies, estimates, and assumptions. As a result, the CEO pay ratios reported by other companies, which may have employed other permitted methodologies or assumptions, and which may have a significantly different work force structure from ours, might not be comparable to our CEO pay ratio. \n

PAY VERSUS PERFORMANCE

\n In accordance with rules adopted by the SEC pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act, we provide the following disclosure regarding executive compensation for our principal executive officers (“PEOs”) and Non-PEO NEOs and Company performance for the fiscal years listed below. Compensation actually paid, as determined under SEC requirements, does not reflect the actual amount of compensation earned by or paid to our executive officers during a covered year. For information regarding the Company’s pay for performance philosophy and how the Company aligns executive compensation with the Company’s performance, refer to the CD&A. \n

\n \n The amounts shown for Compensation Actually Paid have been calculated in accordance with Item 402(v) of Regulation S-K and do not reflect compensation actually earned, realized, or received by the Company’s NEOs. These amounts reflect the Summary Compensation Table Total with certain adjustments as described in footnote 3 below. \n

\n \n Compensation Actually Paid reflects the exclusions and inclusions of certain amounts for the PEOs and the Non-PEO NEOs as set forth below. Equity values are calculated in accordance with FASB ASC Topic 718. Amounts in the Exclusion of Stock Awards column are the totals from the Stock Awards column set forth in the Summary Compensation Table. \n

\n \n The Peer Group TSR set forth in this table utilizes a custom group of peer companies, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report, weighted according to the respective companies’ stock market capitalization at the beginning of each period for which a return is indicated. The comparison assumes $100 was invested for the period starting June 30, 2021, through the end of the listed year in the Company and in the custom group of peer companies used in our performance graph, respectively. The Company’s fiscal year peer group consists of IPG Photonics Corp., Wolfspeed Inc., Lumentum Holdings, Inc., Corning, Inc., MKS Instruments, Inc., and Honeywell International, Inc. Historical stock performance is not necessarily indicative of future stock performance. \n

\n \n We determined Adjusted EBITDA to be the most important financial performance measure used to link Company performance to Compensation Actually Paid to our PEO and Non-PEO NEOs in 2026. See discussion under “Annual Cash Incentive Programs” and “Primary Bonus Program (GRIP)” in our CD&A for an explanation of Adjusted EBITDA, and Appendix B for a reconciliation of this non-GAAP measure to its most directly comparable financial measure calculated and presented in accordance with GAAP. Adjusted EBITDA may not have been the most important financial performance measure for prior years, and we may determine a different financial performance measure to be the most important financial performance measure in future years. \n

\n Ernst & Young LLC (“E&Y”) has served as the Company’s independent registered public accountant since fiscal year 2008. For fiscal year 2026, E&Y rendered professional services in connection with the audit of our financial statements, including review of quarterly reports and other filings with the SEC. E&Y is knowledgeable about our operations and accounting practices, and well qualified to act as our independent registered public accounting firm for fiscal year 2027, and the Audit and Risk Committee has selected it as such. \n

\n Although shareholder ratification of the appointment of our independent registered public accounting firm is not required by our by laws or otherwise, we are submitting the ratification of the Audit and Risk Committee’s selection of E&Y to our shareholders for ratification as what we believe to be a matter of good corporate governance practice. If the selection of E&Y is not ratified, the Audit and Risk Committee will reconsider the appointment of the Company’s independent registered public accounting firm. Even if the selection of E&Y is ratified by our shareholders, the Audit and Risk Committee in its discretion could decide to terminate the engagement of E&Y and engage another firm if the Audit and Risk Committee determines such action to be necessary or desirable. \n

\n The Company incurred the following fees and expenses for services performed by its Independent Registered Public Accounting Firm during fiscal years 2026 and 2025: \n

This category also includes fees billed for the audit of the effectiveness or the Company’s internal controls over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002. \n

\n \n The Audit and Risk Committee Charter provides that the Audit and Risk Committee must pre-approve all audit services and permitted non-audit services to be performed for the Company by its independent auditors in accordance with applicable law. The Audit and Risk Committee may delegate to one or more designated members of the committee the authority to grant pre-approvals, provided such approvals are presented to the committee at a subsequent meeting. Our Audit and Risk Committee pre-approves the retention of E&Y, and its fees for all audit and non-audit services and determines whether the provision of non-audit services is compatible with maintaining its independence. All services provided by E&Y in fiscal 2026 and 2025 were pre-approved by the Audit and Risk Committee after review of each of the services proposed for approval. \n

\n A representative of E&Y is expected to be present at the Annual Meeting, will have the opportunity to make a statement and is expected to be available to respond to any appropriate questions. \n

\n The affirmative vote of at least a majority of the votes that all shareholders present at the Annual Meeting, in person or by proxy, are entitled to cast is required to ratify the appointment of E&Y as the Company’s independent registered public accounting firm for the fiscal year ending June 30, 2027.

REPORT OF THE AUDIT AND RISK COMMITTEE

\n The following is the report of the Audit and Risk Committee with respect to the Company’s audited financial statements for the fiscal year ended June 30, 2026, included in the Company’s Annual Report on Form 10-K. The information contained in this report shall not be deemed to be “soliciting material” or to be “filed” with the SEC. Likewise, it shall not be incorporated by reference into any future filing under the Securities Act of 1933, as amended, or the Securities Exchange Act of 1934, as amended, except to the extent that the Company specifically incorporates it by reference in such filing. \n

MEMBERSHIP AND ROLE OF AUDIT AND RISK COMMITTEE

\n The Audit and Risk Committee is composed of directors who have been determined by the Board to be “independent” and “financially literate” pursuant to the NYSE listing requirements. The Audit and Risk Committee operates under a written charter adopted by the Board. \n

REVIEW WITH MANAGEMENT

\n The Audit and Risk Committee reviews each of the Company’s quarterly and annual reports, including Management’s Discussion and Analysis of Financial Condition and Results of Operations. As part of this review, the Audit and Risk Committee discusses the reports with the Company’s management. It also considers the audit reports prepared by the Independent Accountants about the Company’s annual report, and related matters like the quality of the Company’s accounting principles; alternative methods of accounting under Generally Accepted Accounting Principles, and the Independent Accountant’s preferences in this regard; the Company’s critical accounting policies; and the clarity and completeness of the Company’s financial and other disclosures. \n

\n The Audit and Risk Committee reviewed management’s report on internal control over financial reporting, required under Section 404 of the Sarbanes-Oxley Act of 2002 and related rules. As part of this review, the Audit and Risk Committee reviewed the bases for management’s conclusions in that report, and the report of the Independent Accountants on internal control over financial reporting. Throughout the fiscal year ended June 30, 2026, the Audit and Risk Committee reviewed management’s plan for documenting and testing controls, the results of their documentation and testing, any deficiencies, and the remediation of the deficiencies. \n

REVIEW AND DISCUSSIONS WITH INDEPENDENT ACCOUNTANTS

\n The Audit and Risk Committee also reviewed our consolidated financial statements for 2026 with Ernst & Young LLP (EY), our independent registered public accounting firm for fiscal year 2026, which is responsible for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States. Further, the Audit and Risk Committee reviewed with EY its judgment as to the quality, not just the acceptability, of the accounting principles. In addition, the Audit and Risk Committee met with EY, with and without management present, to discuss the results of its examinations, its evaluations of our internal controls, and the overall quality of our financial reporting. \n

\n The Audit and Risk Committee has received the written disclosures and the letter from EY required by the 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, as modified or supplemented, and has discussed with EY its independence. The Audit and Risk Committee considered the compatibility of non-audit services EY provided to us with EY’s independence. Finally, the Audit and Risk Committee discussed with EY the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board and SEC. \n

CAN I CHANGE OR REVOKE MY VOTE AFTER I VOTE ONLINE OR RETURN MY PROXY CARD?

\n Yes. Even after you have submitted your proxy, you may change or revoke your vote at any time before the proxy is exercised. You may (i) deliver a notice of revocation or deliver a later-dated proxy to the Company’s Secretary at Coherent Corp., 375 Saxonburg Boulevard, Saxonburg, Pennsylvania 16056; (ii) submit another vote via the internet or by telephone; or (iii) vote during the Annual Meeting. Your participation in the Annual Meeting will not automatically revoke a previously submitted proxy. A shareholder’s last vote is the vote that will be counted. \n

WHAT ARE THE RECOMMENDATIONS OF THE BOARD?

\n Unless you give other instructions when you vote, the persons named as proxy holders on the proxy card will vote in accordance with the recommendations of the Board. These recommendations are set forth in the description of each proposal in this proxy statement. In summary, the Board recommends a vote: \n

\n •\n
\n

\n \n FOR election of the nominated slate of Class Three directors for terms expiring in 2029 (see Proposal 1); \n

\n •\n
\n

\n \n FOR approval, on a non-binding advisory basis, of the compensation of our named executive officers as disclosed in this proxy statement (see Proposal 2); and \n

\n •\n
\n

\n \n FOR ratification of the Audit and Risk Committee’s selection of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending June 30, 2027 (see Proposal 3). \n

\n With respect to any other matter that properly comes before the Annual Meeting, the proxy holders will vote as recommended by the Board or, if no recommendation is given, in their own discretion. \n

WHAT ARE ROUTINE AND NON-ROUTINE PROPOSALS?

\n Proposal 3, concerning the ratification of the Audit and Risk Committee’s selection of E&Y as our independent registered public accounting firm for the fiscal year ending June 30, 2027, is considered a routine matter. A broker or other nominee may generally vote in their discretion on routine matters, and therefore no broker non-votes are expected in connection with Proposal 3. \n

\n Proposal 1, concerning the election of the nominated slate of Class Three directors for terms expiring in 2029, and Proposal 2, concerning the approval, on a non-binding advisory basis, of the compensation of our named executive officers as disclosed in this proxy statement, are considered non-routine matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, that organization will inform the inspector of election that it does not have the authority to vote on the matter with respect to your shares. This is generally referred to as a “broker non-vote.” \n

WHAT IS THE EFFECT OF ABSTENTIONS AND BROKER NON-VOTES?

\n Abstentions and broker non-votes will be counted for purposes of establishing a quorum. Abstentions and broker non-votes will not be taken into account in determining the outcome of the election of directors, since they are not considered to be “votes cast”. Abstentions have the effect of a vote “AGAINST” with respect to Proposals 2 and 3. Broker non-votes have no effect on Proposal 2. \n

OTHER INFORMATION

\n The Company will pay the expenses of soliciting proxies to be voted at the annual meeting, including the cost of preparing and posting this proxy statement and the annual report to the internet, and the cost of printing, assembling and mailing the proxy materials and/or the Notice of Internet Availability of Proxy Materials, as applicable, to shareholders. The Company may request persons holding shares in their names, or in the names of their nominees, to send proxy materials to, and obtain proxies from, their principals, and will reimburse such persons for their expense in so doing. \n

SHAREHOLDER PROPOSALS

\n Proposals by shareholders intended for inclusion in the Company’s proxy statement and form of proxy for the annual meeting of the Company expected to be held in November 2027 must be delivered to the Secretary of Coherent Corp. at 375 Saxonburg Boulevard, Saxonburg, Pennsylvania 16056, by June 11, 2027. Rules under the Securities Exchange Act of 1934, as amended, describe the standards as to the submission of shareholder proposals. Additionally, the Board-appointed proxies will have discretionary authority to vote on any proposals by shareholders that are not intended to be included in the Company’s proxy materials for our 2027 annual meeting of shareholders, but are intended to be presented by the shareholder from the floor, if notice of the intent to make such proposal is received by the Secretary at the above address no later than the close of business on July 21, 2027, and no earlier than the close of business on June 21, 2027. Otherwise, such proposals will be considered untimely. Any such notice of intent by a shareholder must also comply with the requirements contained in the Company’s Amended and Restated Bylaws. \n

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

HOUSEHOLDING

\n The term “householding” means that we will deliver only one copy of our annual report and proxy statement to shareholders of record who share the same address and last name unless we have received contrary instructions from you. This procedure reduces our printing costs and mailing costs and fees. Upon written or oral request, we will promptly deliver a separate annual report and proxy statement to any shareholder at a shared address to which a single copy of either of those documents was delivered. \n

\n If you would like to receive a separate copy of the annual report for proxy statement for this meeting or opt out of householding, or if you are a shareholder eligible for householding and would like to participate in householding, please send a request addressed to Chief Legal and Global Affairs Officer and Secretary of Coherent Corp., 375 Saxonburg Boulevard, Saxonburg, Pennsylvania 16056 or by calling +1 (724) 352-4455. Many brokerage firms have instituted householding. If you hold your shares in “street name,” please contact your bank, broker or other holder of record to request information about householding. \n

OTHER MATTERS

\n The Company knows of no other matters to be presented for action at the meeting. However, if other matters properly come before the meeting, votes will be cast on those matters in accordance with the best judgment of the persons acting as proxies. \n

\n \n During the second fiscal quarter of 2025, the Company refined its methodology to report non-GAAP measures. The change does not impact the Company’s financial position, cash flows, or GAAP consolidated results of operations. Prior period non-GAAP financial measures presented in this press release have been recast to conform to the current presentation. \n

\n \n The Company adopted a full-year, normalized tax rate for the computation of the non-GAAP income tax provision for fiscal year 2026. We believe this approach provides investors with a more consistent view of our underlying operating performance. In estimating the full-year non-GAAP normalized tax rate, the Company utilized a full-year financial projection that considers multiple factors such as changes to the Company’s current operating structure, expected reserve changes for the year, and other significant tax matters to the extent they are applicable to the full fiscal year financial projection. In addition to the adjustments described above, this normalized tax rate excludes the impact of share-based awards, amortization of acquisition-related intangible assets, integration and restructuring charges, foreign exchange gain/(loss), and certain tax valuation allowances. \n
