WALTHAM, Mass. — Thermo Fisher Scientific Inc. announced Tuesday that Chief Financial Officer Stephen Williamson will retire from the company on March 31, 2026. He will be succeeded by Jim Meyer, the current vice president of financial operations, who will assume the CFO role effective March 1, 2026.
Williamson, 58, has served as CFO since 2015 and has been with Thermo Fisher since 2001, when he joined as vice president of European financial operations. He will remain on the Company Leadership Team until his retirement and will work closely with Meyer over the coming months to ensure a smooth leadership transition.
“Stephen has played a key role in building the company into the industry leader we are today. He has overseen tremendous growth of the company with our market capitalization increasing nearly 300 percent during his tenure as CFO,” said Marc N. Casper, chairman, president, and CEO of Thermo Fisher. “I’ve worked closely with Stephen for nearly 25 years and have deeply valued his support, guidance and leadership. I wish him the very best in his upcoming retirement.”
Commenting on Meyer’s appointment, Casper added, “As part of our long-planned succession process, we sought a leader with strong financial expertise and deep company knowledge, and Jim is exceptionally well qualified to take on this role. I’ve worked closely with Jim over the past few years and look forward to continuing our partnership as he steps into his new role.”
Meyer, 46, joined Thermo Fisher in 2009 and has held a series of finance leadership roles across the company’s Laboratory Products, Analytical Instruments, and Customer Channels businesses. He was appointed vice president of financial operations in January 2023. Prior to joining Thermo Fisher, Meyer worked at PricewaterhouseCoopers.
