Viatris Inc

Management of Viatris Inc. is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. In order to evaluate the effectiveness of internal control over financial reporting, management has conducted an assessment, including testing, using the criteria in Internal Control - Integrated Framework (2013), issued by COSO. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate.

As a result of this assessment, management has concluded that the Company maintained effective internal control over financial reporting as of December 31, 2024 based on the criteria in Internal Control - Integrated Framework (2013) issued by COSO.

Our independent registered public accounting firm, Deloitte & Touche LLP (PCAOB ID No.34), has audited the effectiveness of the Company’s internal control over financial reporting. Deloitte & Touche LLP’s opinion on the Company’s internal control over financial reporting appears on page 82 of this Annual Report on Form 10-K.
