He holds a BSc in Chemistry and Biology as well as an HBSc in Pharmacology and Toxicology from the University of Western Ontario and received his MS in International Management from the American Graduate School of International Management.

Elisha Finney is an experienced former public company executive officer and current public company director who most recently served a long and distinguished career at Varian Medical Systems, Inc. as Executive Vice President and Chief Financial Officer, overseeing corporate accounting, corporate communications and investor relations, internal audit, risk management, tax and treasury, and corporate information systems.

She received her B.A. in Risk Management and Insurance from the University of Georgia and her master’s degree in Finance from Golden Gate University.

Retiring from the Viatris board of directors are Neil Dimick and Ian Read. Both have served on the Viatris board for over two years since the company was created through the combination of Mylan N.V. and Pfizer’s Upjohn business in November 2020 (the “Combination”).

Robert J. Coury, Executive Chairman of Viatris said, “On behalf of the entire Viatris board of directors, we cannot thank Neil and Ian enough for their service and significant contributions over these past years. I have personally and sincerely appreciated their partnership and collaboration as we worked together to lay out a very clear and deliberate two-phased strategy to return Viatris back to growth. I wish each of them the very best in their future endeavors.”

Coury continued, “We are also pleased to welcome Scott Smith and Elisha Finney to the board. Scott’s vast commercial and pharmaceutical expertise include not only strong M&A and business development skills, but also sales and marketing, commercial operations and new product development, including regulatory and clinical development strategies. I believe that the Viatris board will not only benefit from Scott’s deep industry knowledge, experience and overall business mindset, but will also be timely as we continue our strategy of moving the company up the pharmaceutical value chain.

“Additionally, Elisha, as a former strong public company senior executive with extensive board credentials, will add value to Viatris’ board in the areas of finance, regulatory, reimbursement and risk management. We look forward to working with both Scott and Elisha and the contributions that each will bring to our board.”

Neil Dimick said, “It has been my true pleasure to have been able to serve on the Mylan board from 2005 to 2020 and now the Viatris board since the Combination. During this time, I have witnessed firsthand the consistent, significant growth of these companies. I want to personally thank Robert and the entire board of directors for their partnership and strong collaboration. I wish Viatris nothing but the best and am happy to be able to retire knowing that I was able to contribute in paving the way for the company’s next phase of growth.”

Ian Read stated, “I have sincerely appreciated my time on the Viatris board of directors since the Combination. I believe we have made significant progress during this period not only in establishing an incredibly strong foundation for the company, but in achieving consistent execution against our strategic and financial objectives. As I conclude my tenure, and as Viatris prepares to enter into phase 2 of its evolution, I am honored to have had the opportunity to contribute to its success.”
