Company Reaffirms Fiscal 2024 Guidance

PITTSBURGH, Feb. 20, 2024 (GLOBE NEWSWIRE) – Coherent Corp. (the “Company” or “Coherent”) (NYSE: COHR), a global leader in materials, networking, and lasers, today announced that Dr. Vincent (“Chuck”) D. Mattera, Jr., has informed the Coherent Board of Directors (“the Board”) of his intent to retire as CEO following the commencement of employment of his successor. Dr. Mattera’s intention to retire does not reflect a dispute or disagreement with the Company. In parallel with today’s announcement, the Company is reaffirming the guidance set forth in that certain Shareholder Letter dated as of February 5, 2024 and furnished on such date as an exhibit to a Current Report on Form 8-K filed on that day.

Coherent’s Board of Directors has retained a leading executive search firm to immediately commence a comprehensive search process, which will include evaluating internal and external candidates, to identify a new CEO to lead the Company into the future. A subcommittee of the Board has been formed to oversee the search process.

Dr. Mattera, 68, has served with Coherent for 20 years, the last eight of which have been as CEO. He is the Company’s third CEO since its founding in 1971 as II-VI Incorporated. He has also served as Chair of the Company’s Board of Directors since November 2021. During his tenure, Dr. Mattera led the transformation of II-VI, a premier supplier of engineered materials and optoelectronic components, into Coherent Corp., a global, diversified company enabling multiple irreversible megatrends in the industrial, communications, electronics, and instrumentation markets. Over his 20 years, the Company’s annual revenue grew from $150 million in fiscal 2004 to more than $5 billion in fiscal 2023.

“Leading this 53-year-old company through its multi-decade growth transformation has been an incredible privilege,” said Dr. Mattera. “I want to acknowledge and deeply thank our employees, investors, customers, partners, and especially our Leadership Team, as well as my fellow Board members, for our shared accomplishments and for helping make my years at Coherent so rewarding and impactful.

“Since the strategic combination of II-VI and Coherent two years ago, I am most proud of the tremendous progress we have made to integrate our two organizations, optimize synergies, and place the Company in an advantaged position for accelerated growth. With Coherent on a clear path to improved margins and continued profitable growth, its track record of product leadership, customer intimacy, operational excellence, and the unstoppable imagination of our world-class people, I believe that now is the right time to look toward the next chapter of the Company’s transformation,” Dr. Mattera said. “I have never been more excited about Coherent’s prospects and look forward to transitioning to the next generation of leadership to execute new value creation opportunities and continue to unlock longer-term profitable growth. I am confident that Coherent’s extraordinary track record of financial and operational excellence, and its broad and deep foundation in materials, networking, and lasers, will pave the way for our sustained success. The future of Coherent is bright, and I am pleased to continue to play a role in delivering on our near-term strategic priorities and driving the seamless execution of our leadership succession plan, with the support and involvement of the Board.”

“Throughout Chuck’s tenure, he played a critical role in leading the development and execution of our strategic growth plans, helping transform the Company into a true market leader and redefine the future through breakthrough technologies. He has spent his entire career in and around the industry and has been instrumental in advancing the sector into one that is fundamental in today’s ever-changing environment. As CEO since 2016, Chuck has driven an over 700% increase in the Company’s market capitalization, to over $9 billion, and the Board and I can’t thank him enough for his outstanding contributions and stalwart leadership over the last 20 years. We look forward to continuing our work with Chuck in the near term and appreciate his continued leadership to ensure a smooth transition,” said Enrico DiGirolamo, Lead Independent Director.

“Since Coherent’s founding, the Company has been squarely focused on emerging trends and megatrends, investing in innovation to better anticipate what’s now, next, and beyond, and forming key strategic partnerships to best support our customers,” said Mr. DiGirolamo. “The markets we serve are changing rapidly, and, as we look ahead to our next chapter, we will continue to best position ourselves to capitalize on those areas where we see the greatest opportunities for growth and value creation. This includes finding the right new CEO, supported by seasoned business leaders and our exceptional leadership team, to steer our company forward, enhance our operating performance, and further strengthen our financial foundation.”
