#### Viatris Announces Chief Financial Officer Transition

*Theodora "Doretta" Mistras to Depart; Paul Campbell Named Interim CFO*

**PITTSBURGH – May 4, 2026** – Viatris Inc. (Nasdaq: VTRS), a global healthcare company, today announced that Theodora "Doretta" Mistras, Chief Financial Officer, will depart the Company for a new professional opportunity.

Viatris has named Paul Campbell, currently Chief Accounting Officer and Corporate Controller, as interim Chief Financial Officer, effective May 8, 2026, while the Company conducts its search for a permanent successor. Mistras will remain with the Company until May 22, 2026, to facilitate a seamless transition.

"We thank Doretta for her significant contributions, which have helped prepare the Company to enter a period of sustainable future growth," said **Scott A. Smith, CEO, Viatris**. "Given Paul's deep knowledge of Viatris and his financial expertise and experience, we are confident he is the right transitional leader to maintain continuity and operational discipline while we focus on positioning the Company for sustained long-term growth."

Campbell brings more than two decades of experience in accounting, financial operations and corporate leadership to the position. In his current role as Chief Accounting Officer and Corporate Controller of Viatris, Campbell oversees the Company's global accounting and finance operations. Since joining Viatris' legacy company, Mylan, in 2002, Campbell has played a key role in strengthening financial processes, supporting strategic initiatives and maintaining disciplined financial management across the organization.

Prior to his current role, Campbell served as Mylan's Chief Accounting Officer, Senior Vice President and Controller, where he was responsible for the Company's accounting, financial operations and reporting. During his tenure, he has held positions of increasing responsibility across internal audit, business development, corporate development and operations finance, contributing to the Company's growth and transformation. Earlier in his career, Campbell spent nearly a decade at Deloitte & Touche, where he served as a Senior Manager in Audit. Campbell holds a Bachelor of Science in Accounting from Pennsylvania State University.

Viatris will release financial results for the first quarter of 2026 on May 7, 2026, and will host a conference call at 8:30 a.m. ET to discuss the results.
