Roche has announced the appointment of Dan Malarek as President and CEO of Roche Diagnostics North America, effective August 1, 2026. Malarek currently serves as Chief Executive Officer of Foundation Medicine Inc., an independent affiliate of the Roche Group. Malarek succeeds Brad Moore, who will retire at the end of July after nearly 10 years with Roche. The role will remain based at Roche Diagnostics’ North America headquarters in Indianapolis and report to Matt Sause, Global CEO of Roche Diagnostics.

To further strengthen commercial execution across the region, Antonio Vergara has been appointed Chief Commercial Officer of Roche Diagnostics U.S., a newly created role also beginning August 1, 2026. Reporting directly to Malarek, Vergara will lead the commercial organization and its business units.

Malarek joined the Roche Group in 2007 through the Perspectives Management Development Program and built a diverse, nearly two-decade career across multiple leadership positions. Within the Diagnostics division, his experience included serving as Head of Marketing and Business Development in Diabetes Care, Lifecycle Leader in Molecular Diagnostics, and General Manager of Roche Diagnostics Norway. He later elevated to Global Head of Marketing & Customer Insights for Roche Diagnostics before transitioning to lead Foundation Medicine Inc. as its Chief Executive Officer. 

Concurrent with Malarek’s transition, Foundation Medicine Chief Operating Officer Vera Grossmann has been appointed interim Chief Executive Officer, effective August 1, 2026, while a search for a permanent successor is underway. 

Vergara brings three decades of experience across finance, commercial and general management roles at the company. Since joining Roche in 1996 as a financial controller, he has held leadership positions across multiple geographies, including serving as President and Head of Diagnostics Latin America. Most recently, Vergara served as Senior Vice President of the U.S. Core Lab and Near Patient Care business.
