Coherent and its board of directors has named Andreas “Andy” W. Mattes, previously senior advisor at McKinsey & Company and president and chief executive officer of Diebold Nixdorf, as the company’s new president and chief executive officer and a member of the board of directors, effective immediately. Yesterday’s appointment follows the announcement a year ago that Dr John R. Ambroseo will retire from his positions as president and CEO and member of the board no later than April 2021. John Ambroseo will transition to become a special advisor to the company until the end of next year, ensuring a smooth and successful transition.

On Andy Mattes’ recommendation, the board of directors has also appointed Dr Mark Sobey, a 13-year senior executive of the company, as new executive vice president and chief operating officer, effective immediately.

“Following an extensive and thorough search, we are delighted to welcome Andy Mattes as new CEO, ushering in an exciting new chapter of the company’s long and storied history”, said Dr Garry Rogerson, Coherent’s chairman of the board. “Andy is a proven leader and has significant experience running and growing global technology businesses, including hardware, software and services. His strategic experience and leadership skills coupled with Mark Sobey’s deep industry knowledge, supported by our experienced senior staff, provides us with the right executive leadership to drive this next chapter for our business.”

Rogerson added, “We are extremely grateful for John Ambroseo’s steadfast leadership and commitment to Coherent throughout his three decades at the company. During his tenure as CEO, Coherent became a technology innovator and market leader in the laser industry, and we thank John for all he has done over the past 18 years as CEO to bring us to where we are today. I am looking forward to working closely with Andy Mattes in the years to come.”
