Business Development Transactions

Below is a summary of significant business development activity thus far in 2025.

In March 2025, Merck and Jiangsu Hengrui Pharmaceuticals Co., Ltd. (Hengrui Pharma) announced that the companies have entered into an exclusive license agreement for HRS-5346, an investigational oral small molecule Lipoprotein(a) inhibitor, which is currently being evaluated in a Phase 2 clinical trial in China. Under the agreement, Hengrui Pharma granted Merck exclusive rights to develop, manufacture and commercialize HRS-5346 worldwide, excluding the Greater China region. Hengrui Pharma will receive an upfront payment of $200 million and is eligible to receive future contingent payments associated with certain developmental, regulatory and sales-based milestones, as well as tiered royalties on future net sales of HRS-5346, if approved. Closing of the proposed transaction is subject to approval under the Hart-Scott-Rodino Antitrust Improvements Act and other customary conditions. Merck expects to record a pretax charge of $200 million to Research and development expenses, or approximately $0.06 per share, upon closing, which is anticipated in the second quarter of 2025.

Also in March 2025, Merck acquired the Dundalk, Ireland facility of WuXi Vaccines (a wholly owned subsidiary of WuXi Biologics), which was accounted for as an asset acquisition. Merck paid $437 million at closing which, combined with previous consideration transferred under a prior manufacturing arrangement with WuXi Vaccines related to this facility, resulted in $759 million being recorded as assets under construction within Property, Plant and Equipment. There are no future contingent payments associated with the acquisition.

Pricing and Tariffs

Global efforts toward health care cost containment continue to exert pressure on product pricing and market access worldwide. Changes to the U.S. health care system as part of health care reform, as well as increased purchasing power of entities that negotiate on behalf of Medicare, Medicaid, and private sector beneficiaries, have contributed to pricing pressure. In 2021, the U.S. Congress passed the American Rescue Plan Act, which included a provision that eliminated the statutory cap on rebates drug manufacturers pay to Medicaid beginning in January 2024. As a result of this provision, the Company paid state Medicaid programs more in rebates than it received on Medicaid sales of Januvia (sitagliptin), Janumet (sitagliptin and metformin HCl) and Janumet XR (sitagliptin and metformin HCl extended release) in 2024. In 2022, the U.S. Congress passed the Inflation Reduction Act (IRA), which made significant changes to how drugs are covered and paid for under the Medicare program, including the creation of financial penalties for drugs whose prices rise faster than the rate of inflation, redesign of the Medicare Part D program to require manufacturers to bear more of the liability for certain drug benefits (which has taken effect in 2025), and government price-setting for certain Medicare Part D drugs (starting in 2026) and Medicare Part B drugs (starting in 2028). Government price setting may also impact pricing in the private market negatively affecting the Company’s performance. In 2023, the U.S. Department of Health and Human Services (HHS), through the Centers for Medicare & Medicaid Services (CMS), selected Januvia for the first year of the IRA’s “Drug Price Negotiation Program” (Program). Pursuant to the IRA’s Program, a government price was set for Januvia, which will become effective on January 1, 2026. In January 2025, the U.S. Department of HHS, through the CMS, announced that Janumet and Janumet XR would be in included in the second year of the IRA’s Program, with government price setting to become effective on January 1, 2027. The Company has sued the U.S. government regarding the IRA’s Program. Additionally, increased utilization of the 340B Federal Drug Discount Program and restrictions on the Company’s ability to identify inappropriate discounts are having a negative impact on Company performance. Furthermore, the Executive Branch and Congress continue to discuss legislation designed to control health care costs, including the cost of drugs. In several international markets, government-mandated pricing actions have reduced prices of generic and patented drugs. In addition, the Company’s sales performance in the first three months of 2025 was negatively affected by other cost-reduction measures taken by governments and other third parties to lower health care costs. The Company anticipates all of these actions and additional actions in the future will continue to negatively affect sales and profits.

The U.S. government has implemented tariffs on certain foreign imports into the U.S. The impact of the tariffs on Merck’s business depends on a number of factors including the duration, scope and amount of the tariffs, as well as the extent of any measures that have been or will be taken by any affected countries, including tariffs imposed by foreign governments. At this time, the Company anticipates that tariffs implemented to date will result in approximately $200 million of additional expenses in 2025 (which will be primarily reflected within Cost of sales) the vast majority of which relate to China, largely related to the importation of products into China. However, future changes to tariffs could have a further adverse effect on the Company’s business. In particular, the U.S. government has indicated that it intends to impose tariffs on pharmaceutical products, although the specific amount and timing of any such future tariffs has not been provided.

Operating Results

Sales

- 28 -

Worldwide sales were $15.5 billion in the first quarter of 2025, a decrease of 2% compared with the first quarter of 2024, reflecting declines in vaccines, virology and immunology, partially offset by growth in oncology, cardiovascular, diabetes and animal health. The decline in vaccines was primarily due to lower combined Gardasil (Human Papillomavirus Quadrivalent [Types 6, 11, 16 and 18] Vaccine and Recombinant)/Gardasil 9 (Human Papillomavirus 9-valent Vaccine, Recombinant) sales, partially offset by the U.S. launch of Capvaxive (Pneumococcal 21-valent Conjugate Vaccine). The decline in virology was primarily due to lower sales of Lagevrio (molnupiravir) and the decline in immunology resulted from the transfer of marketing rights for Remicade and Simponi back to Johnson & Johnson on October 1, 2024. Growth in the oncology franchise was largely due t

Management of the Company, with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures over financial reporting.

CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS

This report and other written reports and oral statements made from time to time by the Company may contain so-called “forward-looking statements,” all of which are based on management’s current expectations and are subject to risks and uncertainties which may cause results to differ materially from those set forth in the statements. One can identify these forward-looking statements by their use of words such as “anticipates,” “expects,” “plans,” “will,” “estimates,” “forecasts,” “projects” and other words of similar meaning, or negative variations of any of the foregoing. One can also identify them by the fact that they do not relate strictly to historical or current facts. These statements are likely to address the Company’s growth strategy, financial results, product approvals, product potential, or development programs. One must carefully consider any such statement and should understand that many factors could cause actual results to differ materially from the Company’s forward-looking statements. These factors include inaccurate assumptions and a broad variety of other risks and uncertainties, including some that are known and some that are not. No forward-looking statement can be guaranteed and actual future results may vary materially.

The Company does not assume the obligation to update any forward-looking statement. One should carefully evaluate such statements in light of factors, including risk factors, described in the Company’s filings with the Securities and Exchange Commission, especially on Forms 10-K, 10-Q and 8-K. In Item 1A. “Risk Factors” of the Company’s Annual Report on Form 10‑K for the year ended December 31, 2024, filed on February 25, 2025, the Company discusses in more detail various important risk factors that could cause actual results to differ from expected or historic results. The Company notes these factors for investors as permitted by the Private Securities Litigation Reform Act of 1995. One should understand that it is not possible to predict or identify all such factors. Consequently, the reader should not consider any such list to be a complete statement of all potential risks or uncertainties.
