Emergent BioSolutions Announces Retirement of Chief Financial Officer Richard S. Lindahl

•Appointment of Frank Vargo, VP, Treasurer, to Interim CFO effective January 1, 2027

GAITHERSBURG, Md., October 16, 2026 (GLOBE NEWSWIRE) -- Emergent BioSolutions Inc. (NYSE: EBS) today announced that Richard S. Lindahl, executive vice president, chief financial officer, will retire from the Company effective December 31, 2026. Frank Vargo, vice president, treasurer, will assume the role of interim chief financial officer effective January 1, 2027. To support a seamless transition, Rich will serve as a senior executive advisor from January 1 through March 31, 2027.

“On behalf of the Board of Directors and our colleagues, I want to thank Rich for his exceptional leadership, partnership and commitment to Emergent, and importantly, his dedication to our mission to protect and save lives,” said Joe Papa, president and chief executive officer of Emergent. “We are grateful that he will continue to advise the Company during the first quarter of 2027 as we complete this transition, and we wish him all the best in retirement. Since joining Emergent in 2019, Frank has been integral in driving our strategic priorities forward, and I am confident he will ensure continuity and disciplined financial stewardship as interim chief financial officer.”

Before coming to Emergent in 2018, Rich served as CFO of publicly traded best practices and technology solutions company CEB, SVP and treasurer of Sprint Nextel Corporation, and VP of finance at Pocket Communications, Inc., and held various positions at MCI Communications Corp. and Deloitte & Touche LLP. He currently serves on the board of directors of Compass Therapeutics, Inc.

“During my nearly nine years at Emergent, I am proud of the contributions our team made to the Company’s growth, the resilience we demonstrated through some extraordinarily challenging periods, and the progress we made in strengthening the business for the future,” said Lindahl. “I am deeply grateful to the Board, my colleagues and the many people across Emergent who made this such a rewarding chapter of my career, and I am committed to ensuring a smooth and successful transition. Looking ahead, I am excited to remain professionally engaged through board service and advisory work while making more time for family, friends, travel and personal pursuits.”

The leadership transition reflects Emergent’s continued execution of its multi-year transformation plan, which is focused on strengthening the business, improving operating performance and positioning the Company for long-term, sustainable growth.
