Bruker announces the addition of Diagnostics Industry leader

BILLERICA, Massachusetts - December 8, 2025 – Bruker Corporation (Nasdaq: BRKR) today announced that its Board of Directors has added Jack J. Phillips to serve on its board of directors, effective as of January 1st, 2026. Mr. Phillips is a senior healthcare industry executive with over 30 years of leadership experience in the diagnostics industry.

Frank H. Laukien, chairman, president and CEO of Bruker Corporation, stated: “Bruker is delighted to add Jack to our board of directors. His broad and deep diagnostics experience, strategic acumen and market development experience will be very valuable to Bruker and our board. I admire Jack’s proven ability to translate scientific innovations into clinical impact for patient benefit and to accelerate profitable business growth in diagnostics. Jack’s addition to our board is timely, as we broaden our infectious disease diagnostics portfolio, and increasingly leverage our unique disease biology research tools for opportunities in specialty diagnostics.”

Jack Phillips served as President & CEO of Accelerate Diagnostics from 2020-2025, pioneering rapid antibiotic susceptibility testing (AST) technology for hospitals and infectious disease doctors combating serious bacterial infections, life-threatening sepsis and antibiotic resistance.

Previously, Jack was President & CEO of Roche Diagnostics North America from 2010-2020, where he led the portfolio across clinical chemistry, immunodiagnostics, as well as molecular, tissue and point-of-care diagnostics, and digital pathology, all further strengthening Roche’s leadership position in the global in vitro diagnostics (IVD) industry.

From 1999-2010, Jack was Senior VP and General Manager, North America, for Ventana Medical Systems, helping establish tissue and companion diagnostics as standards of care. His career has centered on advancing innovation to clinical translation for patient benefit and business impact through strategy, market development and operational excellence. Jack serves on the Board of Trustees of Tucson Medical Center, and he previously was a board member of AdvaMedDx. He holds a B.S. in Marketing from Northern Kentucky University.

“It’s a great honor to join the Board of Directors at Bruker Corporation, a company with an entrepreneurial culture and a unique dedication to innovation and translation that I really admire.” said Mr. Phillips. “Throughout my career, I’ve seen diagnostics not as siloed technologies, but as a connected ecosystem that turns biological insight into clinical and economic impact, and I look forward to bringing that experience and vision to Bruker.”
