COHERENT CORP. SUPPLEMENTAL PROXY MATERIALS

Coherent Corp. (the “Company”) is providing the following supplemental information regarding the Compensation Discussion and Analysis disclosures presented in the Company’s proxy materials for the 2024 Annual General Meeting of Shareholders to be held on November 14, 2024.

2024 CEO Succession Supported Continued Shareholder Value Creation

As part of its thoughtful CEO succession planning process, the Company executed a seamless CEO succession in June 2024 with the appointment of Jim Anderson as the Company’s next CEO. Maintaining stability of the executive team throughout the CEO search process was critical to the business. Since Mr. Anderson’s appointment as CEO, the Company and its management team have continued to drive sustained growth, delivering a nearly 62% stock price increase through October 31, 2024.

Through its comprehensive CEO search process and assessment of internal and external candidates, the Board of Directors determined that Mr. Anderson was an ideal leader to take the Company forward based on his fresh external perspective and deep knowledge from his prior experience of the Company’s rapidly changing market environment, operational expertise and innovation-first approach, which the Board of Directors deemed necessary to further advance the Company’s strategic market positioning and lead the next phase of growth.

Former CEO’s Transition Compensation Preserved the Foundation for the Company’s Growth in Alignment with the Company’s and Shareholders’ Interests

The successful transition to the Company’s next CEO was supported by a robust retention plan implemented by the Board of Directors to secure the commitment of continued service from the Company’s former CEO, Dr. Vincent D. Mattera, Jr. during the CEO search and onboarding process, ensuring continuity of the critical relationships he built with the Company’s employees, customers, suppliers, government officials and key partners, among other considerations.

The retention package was an exception from the Company’s regular compensation practices, which was necessitated by the strategic need to preserve the Company’s growth foundation built by the visionary leadership of Dr. Mattera. Over his CEO tenure, since 2016, he delivered total shareholder return of 171.83%, and the Company’s market capitalization increased from approximately $1.6 billion to approximately $9.6 billion. Under his guidance, the Company added several new platforms, expanded its IP portfolio and broadened its product roadmap. Dr. Mattera led the acquisition of Finisar in 2019 and the transformative combination between II-VI Incorporated and Coherent in 2022. These strategic efforts positioned the Company as a key player in new markets with increased global reach and significant transformative opportunities to lead its next phase of growth.

With these considerations in mind, on February 17, 2024, the Company and Dr. Mattera entered into an agreement (the “CEO Succession Agreement”), as described in detail in the section titled “Compensation Related to Leadership Transition” beginning on page 54 of our 2024 Proxy Statement.

Based on the Company’s performance to date, which was accelerated by the appointment of Mr. Anderson as the Company’s new CEO, the Board of Directors believes the evidence shows that the transition compensation provided to Dr. Mattera was reasonable and essential to support a smooth transition of the CEO role to Dr. Mattera’s successor and the Company’s strong shareholder value creation.

We are pleased that both Institutional Shareholder Services (ISS) and Glass Lewis assessed the sign-on compensation provided to Mr. Anderson upon his appointment to the CEO role to be reasonable and viewed our overall approach to annual executive compensation as aligned with Company performance and our shareholders’ interests.

Therefore, we respectfully urge you to vote “FOR” the non-binding advisory vote to approve compensation paid to Named Executive Officers in fiscal year 2024.
