In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2025, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.

Goodwill – Viatris Inc. Europe and JANZ Reporting Units – Refer to Note 8 to the financial statements.

Critical Audit Matter Description

The Company performed an annual goodwill impairment test as of April 1, 2024. As of April 1, 2024, the Company had approximately $9.7 billion of consolidated goodwill, $3.86 billion and $0.62 billion of which was allocated to its Europe and JANZ reporting units, respectively. The Company’s evaluation of goodwill for impairment involves the comparison of the estimated fair value of each reporting unit to its carrying value. The Company performed its valuation analysis, using an income-based approach, to determine the fair value of its Europe and JANZ reporting units. The determination of the fair value requires management to make significant estimates and assumptions that affect the reporting unit’s expected future cash flows. These estimates and assumptions, utilizing Level 3 valuation inputs, primarily include, but are not limited to, discount rates, terminal growth rates, operating income before depreciation and amortization, and capital expenditures forecasts. The fair value of the Europe reporting unit exceeded its carrying value by approximately $0.88 billion, or 7.9% as of April 1, 2024. The Company recorded a goodwill impairment charge of $321.0 million during the second quarter related to the JANZ reporting unit. The impairment charge was primarily the result of a 1.0% increase in the discount rate and a 0.5% reduction in the terminal growth rate assumption for the reporting unit.

Given that the Europe and JANZ reporting unit’s revenues are sensitive to changes in consumer demand, the approval of new product launches, the expansion of existing products into new jurisdictions (which have differentiated distribution and commercialization models throughout the regions), and the impact of business development activity, auditing management’s judgments regarding forecasts of future revenues, and the selection of the discount rates and terminal growth rates required a high degree of auditor judgment and an increased extent of effort, including the need to involve our fair value specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the forecasts of future revenues (“forecasts”), and the selection of the discount rates and terminal growth rates for the Europe and the JANZ reporting units included the following procedures, among others:

•We tested the effectiveness of controls over the review of the goodwill impairment tests, including those over the development of the business forecasts of future revenues and the selection of the discount rates and terminal growth rates.

•We evaluated management’s ability to accurately forecast future revenues of the Europe and JANZ reporting units by comparing actual results to management’s historical forecasts.

•We evaluated the reasonableness of management’s revenue forecasts by comparing the projections to (1) historical results, (2) internal communications to management and the Board of Directors, and (3) forecasted information included in Company press releases. We also considered third party reports related to macroeconomic and industry trends and made inquiries of management, including various regional commercial and operations leaders to assess key inputs in the forecast assumptions.

•With the assistance of our fair value specialists, we evaluated the reasonableness of the valuation methodology, discount rates, and terminal growth rates, including (1) testing the source information underlying the determination of the discount rates and terminal growth rates and the mathematical accuracy of the calculations, (2) developing a range of independent estimates and comparing those to the discount rates selected by management, and (3) considering third party macroeconomic reports.

Net Revenue Provisions – Sales Returns Accrual at MPI – Refer to Note 3 to the financial statements.

Critical Audit Matter Description

The Company provides customers with the ability to return product, which varies country by country in accordance with local practices, generally within a specified period prior (six months) and subsequent (twelve months) to the expiration date. The Company’s estimate of the provision for returns is generally based upon historical experience with actual returns. The returns reserve at Mylan Pharmaceuticals Inc. (MPI) represents a significant component of the global sales returns reserve as of December 31, 2024.

Estimating the amounts to be accrued for returns requires significant estimation as management’s model utilizes historical experience with actual returns and considers levels of inventory in the distribution channel, product dating and expiration period, size and maturity of the market prior to a product launch, entrance into the market of additional competitors, and changes in the regulatory environment. Given the volume of sales returns and the level of estimation uncertainty involved, auditing management’s judgments required a high degree of auditor judgment and an increased extent of effort.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Net Revenue Provisions – Sales Returns Accrual at MPI included the following, among others:

•We evaluated the Company’s methodology and assumptions in developing their sales returns accrual model, including assessing the completeness and accuracy of the underlying data used by management in their estimates.

•We tested the effectiveness of controls over the calculation of the sales returns reserve at MPI.

•We compared prior period sales returns accruals to sales returns credits subsequently issued to evaluate management’s ability to accurately forecast sales returns activity.

•We developed independent expectations of product-level sales returns accruals and sales returns accruals in the aggregate using the following: 1) historical sales and returns activity, 2) remaining shelf life information, 3) finished goods inventory on-hand at the end of the period, and 4) adjustments for known or anticipated sales return activity based on market dynamics (market prior to Viatris launch, impact of competition, and overall regulatory environment) and compared those to the recorded amounts.

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances.

Definition and Limitations of Internal Control over Financial Reporting

A company’s 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 generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

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.
