Exhibit 99.1

Robert J. Coury Remarks at the 2023 Viatris Annual Meeting of Shareholders

The End of One Era and The Beginning of Another

Dear Fellow Shareholders,

Over twenty years ago when I first joined our legacy company Mylan, we identified an unmet need in the global healthcare industry and set out to fill it by building a true one-of-a-kind global platform uniquely positioned to bridge the traditional divide between brands and generics.

We sought to combine the best of both to address global healthcare needs more holistically and bring access to more patients worldwide by building scale across manufacturing, geographic reach, product portfolio, R&D and our balance sheet.

It has been a journey unlike any other, and after completing the foundational work to establish Viatris, we have officially realized that vision. Today, Viatris stands tall, solid, and squarely on the path to continuing to make a real difference in healthcare for many years to come.

The Creation of Our Strong Foundation

Building upon Mylan’s legacy and the combination of Mylan and Pfizer’s Upjohn business in 2020, we announced a new business model dedicated to maximizing total shareholder return (TSR) and outlined a clear two-phased strategic plan. Phase 1, from the creation of Viatris until today, focused on achieving key milestones. For example:

Phase 2 (2024 and Beyond): Setting Out a New Course for Growth

As a result of having achieved our original bold vision, Viatris is not just a generics company or a brand company or even just a specialty company, we are a new kind of healthcare company—a Next-Gen Hybrid Global Pharmaceutical Company with a relentless focus on continuing to deliver access to high quality medications at scale.

In Phase 2, beginning in 2024, we will focus our work over the next decade and beyond on building on our current strengths, investing up the value chain, and adding innovation across the full healthcare spectrum in a way we believe no other company in our sector has before.

To be clear, Phase 2 is not about changing course. It is simply about adding to what we have already built to date.

For example, we expect our current global platform to continue to produce powerful, substantial, and strong free cash flows. This will enable us to deliver on our future capital allocation priority of returning approximately 50% of our free cash flow generation to shareholders, while we use the remainder as follows:

Where a lot of companies need to rely on outside financial resources to invest in themselves in order to fuel their growth, we are extremely proud that at Viatris we can rely on ourselves.

Transitioning Our Leadership

As I depart the board of directors and move into my new role as Chairman Emeritus and Strategic Advisor, I have never been more proud or more confident in the strength and position of our company. The vision I set out more than two decades ago has truly become a reality.

As a result, it has provided the opportunity for us to be able to undertake a clear and orderly transition of our leadership. Doing so will continue to enhance the company’s progress and growth going forward.

With Viatris’ powerful foundation now secure, the board of directors has elected Melina Higgins as the next Viatris Board Chair. I could not be more proud of this well-deserved recognition. With Melina’s election and Scott A. Smith fully at the helm as our new CEO and continuing to solidify his new organizational structure in the focus areas previously mentioned, I have never been more excited about, or more confident in, the future prospects of our Company, our colleagues and all of our stakeholders, including our shareholders.

With that said, I would like to thank all of our current and former shareholders for their support, and I cannot thank enough our thousands of employees both past and present around the world, and all of our current and former directors of the board who have served the Company from when I first joined Mylan until today. It is their tireless efforts and steadfast commitment, as well as the sacrifices and support of their families, that truly put Viatris in the powerful position we find ourselves in today. They should be recognized and applauded, and we should all be so very proud.

Non-GAAP Financial Measures

These remarks include the presentation and discussion of certain financial information that differs from what is reported under U.S. GAAP. These non-GAAP financial measures, including, but not limited to, free cash flow and long-term gross leverage target are presented in order to supplement investors’ and other readers’ understanding and assessment of the financial performance of Viatris. Free cash flow refers to U.S. GAAP net cash provided by operating activities less capital expenditures. Investors and other readers should consider non-GAAP measures only as supplements to, not as substitutes for or as superior measures to, the measures of financial performance prepared in accordance with U.S. GAAP.

Long-Term Gross Leverage Target

The stated forward-looking non-GAAP financial measure of long-term gross leverage target of 3.0x, with a range of 2.8x – 3.2x, is based on the ratio of (i) targeted notional gross debt and (ii) targeted Adjusted EBITDA. However, the Company has not quantified future amounts to develop this target but has stated its goal to manage notional gross debt and adjusted EBITDA over time in order to generally maintain or reach the target. This target does not reflect Company guidance. Notional gross debt is the sum of the Company’s long-term debt, including current portion, and short-term borrowings and other current obligations, adjusted for net premiums on various debt issuances and deferred financing fees. Viatris calculates adjusted EBITDA as U.S. GAAP net earnings (loss) adjusted for income tax provision (benefit), interest expense and depreciation and amortization (to get to EBITDA) and further adjusted for share-based compensation expense, litigation settlements and other contingencies, net, and restructuring, acquisition and divestiture related and other special items.
