Fourth-Quarter Sales Performance The following table reflects sales of the company’s top products and significant performance drivers. Fourth Quarter $ in millions 2024 2023 Change Change Ex-Exchange Commentary Total Sales $15,624 $14,630 7% 9% The negative impact of foreign exchange was primarily due to devaluation of Argentine peso, which was largely offset by inflation-related price increases, consistent with practice in that market. Pharmaceutical 14,042 13,141 7% 8% Increase driven by growth in oncology and cardiovascular, partially offset by declines in diabetes, vaccines, immunology and virology. KEYTRUDA 7,836 6,608 19% 21% Growth driven by continued strong global demand from metastatic indications, including increased uptake in bladder and endometrial cancers, as well as increased global uptake in earlier-stage indications, including triple-negative breast cancer and non-small cell lung cancer (NSCLC). The negative impact of foreign exchange was primarily due to devaluation of Argentine peso, which was largely offset by inflation-related price increases. GARDASIL/GARDASIL 9 1,550 1,871 -17% -18% Decline primarily due to lower demand in China, partially offset by higher demand in most international regions, particularly in Japan. PROQUAD, M-M-R II and VARIVAX 594 545 9% 9% Growth primarily due to higher pricing in the U.S. and higher tenders in certain international markets, partially offset by lower demand in the U.S. JANUVIA/JANUMET 487 787 -38% -36% Decline primarily due to lower pricing in the U.S., as well as ongoing generic competition in many international markets and supply constraints in China. BRIDION 449 429 5% 5% Growth primarily due to higher demand in the U.S., partially offset by generic competition in certain international markets, particularly in Japan and Europe. Lynparza* 365 315 16% 18% Growth primarily due to higher global demand. Lenvima* 255 226 13% 14% Growth primarily due to timing of shipments in certain international markets. PREVYMIS 215 175 23% 23% Growth primarily due to higher demand in most markets, particularly in the U.S. WINREVAIR 200 - - - Represents continued uptake since second-quarter launch in the U.S. VAXNEUVANCE 161 176 -9% -9% Decline primarily driven by lower demand in the U.S. due to competition, partially offset by continued uptake from launches in Europe and the Asia Pacific region. WELIREG 160 72 122% 123% Growth primarily driven by higher demand in the U.S., largely attributable to ongoing uptake of a new indication. SIMPONI - 171 N/M N/M Marketing rights in former Merck territories reverted to Johnson & Johnson on Oct. 1, 2024. Animal Health 1,397 1,278 9% 13% Growth primarily driven by higher pricing for both Livestock and Companion Animal product portfolios, as well as sales related to July 2024 acquisition of Elanco aqua business and higher demand for Livestock products. Approximately 3 percentage points of the negative impact of foreign exchange were due to devaluation of Argentine peso, which were largely offset by inflation-related price increases. Livestock 889 808 10% 14% Growth primarily driven by higher demand for poultry products, sales related to acquisition of Elanco aqua business, as well as higher pricing across the portfolio. Companion Animal 508 470 8% 10% Growth primarily driven by higher pricing across the product portfolio. Sales of BRAVECTO were $209 million and $197 million in current and prior year quarters, respectively, which represented growth of 6%, or 10% excluding impact of foreign exchange. Other Revenues** 185 211 -13% 3% Decline primarily due to impact of revenue-hedging activities and lower revenues from third-party manufacturing arrangements, partially offset by payments received for out-licensing arrangements and higher royalty income. *Alliance revenue for this product represents Merck’s share of profits, which are product sales net of cost of sales and commercialization costs. **Other revenues are comprised primarily of revenues from third-party manufacturing arrangements and miscellaneous corporate revenues, including revenue-hedging activities.

Full-year 2024 pharmaceutical sales grew 7% to $57.4 billion. Excluding the unfavorable impact of foreign exchange, pharmaceutical sales grew 10%. Approximately 2 percentage points of the negative impact of foreign exchange were due to devaluation of the Argentine peso, which were largely offset by inflation-related price increases, consistent with practice in that market. Pharmaceutical sales growth was primarily driven by higher sales in oncology, particularly KEYTRUDA and WELIREG, as well as increased alliance revenue from Reblozyl and Lynparza. Higher sales in the cardiovascular franchise, reflecting the successful launch of WINREVAIR, as well as higher sales of certain hospital acute care products, particularly PREVYMIS, also drove revenue growth in 2024. Pharmaceutical sales growth in 2024 was partially offset by lower sales of JANUVIA and JANUMET, primarily reflecting lower pricing in the U.S. and generic competition in many international markets, lower sales of the COVID-19 medication LAGEVRIO, lower sales of GARDASIL/GARDASIL 9 and lower sales of SIMPONI and REMICADE, reflecting the transfer of marketing rights in former Merck territories back to Johnson & Johnson. Full-year 2024 Animal Health sales grew 4% to $5.9 billion. Excluding the unfavorable impact of foreign exchange, Animal Health sales grew 8%. Approximately 2 percentage points of the negative impact of foreign exchange were due to devaluation of the Argentine peso, which were largely offset by inflation-related price increases, consistent with practice in that market. Full-year sales growth was primarily driven by higher pricing across both the Companion Animal and Livestock product portfolios, and higher demand for poultry and swine products, as well as sales related to the acquisition of the Elanco aqua business. Sales of BRAVECTO were $1.1 billion in 2024, which represented growth of 6%, or 8% excluding the impact of foreign exchange.

The increase was primarily due to the favorable effects of product mix (including lower royalty rates related to KEYTRUDA and GARDASIL/GARDASIL 9) and foreign exchange, partially offset by higher manufacturing-related costs (including inventory write-offs) and higher amortization of intangible assets. Gross margin was 76.3% for the full year of 2024 compared with 73.2% for the full year of 2023. The increase was primarily due to the favorable effects of product mix (including lower royalty rates related to KEYTRUDA and GARDASIL/GARDASIL 9) and foreign exchange, partially offset by higher amortization of intangible assets, as well as higher restructuring costs (primarily reflecting asset impairment charges) and higher manufacturing-related costs (including inventory write-offs). Selling, general and administrative (SG&A) expenses were $2.9 billion in the fourth quarter of 2024, an increase of 2% compared with the fourth quarter of 2023. The increase was primarily due to higher promotional and selling costs, partially offset by the favorable impact of foreign exchange and lower restructuring costs. Full-year 2024 SG&A expenses were $10.8 billion, an increase of 3% compared with full-year 2023. The increase was primarily due to higher administrative, promotional, selling and acquisition-related costs, partially offset by the favorable impact of foreign exchange and lower restructuring costs. Research and development (R&D) expenses were $4.6 billion in the fourth quarter of 2024, a decrease of 52% compared with the fourth quarter of 2023. R&D expenses were $17.9 billion for the full year of 2024, a decrease of 41% compared with the full year of 2023. The declines in both the fourth quarter and full year of 2024 were primarily due to lower charges for business development activity, lower intangible asset impairment charges, and the favorable impact of foreign exchange, partially offset by increased compensation and benefit costs and higher clinical development spending. Other (income) expense, net, was $126 million of expense in the fourth quarter of 2024 compared with $78 million of expense in the fourth quarter of 2023. The unfavorability was primarily due to net losses from investments in equity securities compared with net income from investments in equity securities in the prior year quarter, partially offset by lower foreign exchange losses and lower net interest expense. Other (income) expense, net, was $24 million of income in the full year of 2024 compared with $466 million of expense in the full year of 2023, primarily due to a $572.5 million charge in 2023 related to settlements with certain plaintiffs in the Zetia antitrust litigation. The favorability was also due to $170 million of income related to the expansion of an existing development and commercialization agreement with Daiichi Sankyo, as well as lower foreign exchange losses in 2024. Other (income) expense, net, in the full year of 2024 was unfavorably affected by lower net income from investments in equity securities and higher net interest expense compared with 2023. The effective tax rates of 10.2% and 14.1% for the fourth quarter and full year of 2024, respectively, include a 6.2 percentage point favorable impact and a 2.6 percentage point favorable impact, respectively, due to a reduction in reserves for unrecognized income tax benefits, resulting from the expiration of the statute of limitations for assessments related to certain federal tax return years. GAAP EPS was $1.48 for the fourth quarter of 2024 compared with a loss per share of $0.48 for the fourth quarter of 2023, primarily driven by lower charges for business development transactions, operational strength in the business, lower intangible asset impairment charges, and a benefit from the expiration of the statute of limitations for assessments related to the 2020 federal tax return year. GAAP EPS was $6.74 for the full year of 2024 compared with EPS of $0.14 for the full year of 2023. The increase was primarily driven by lower charges for business development transactions, operational strength in the business, lower intangible asset impairment charges, a benefit from the expiration of the statute of limitations for the 2020 and 2019 federal tax return years, and a charge in the prior year for settlements with certain plaintiffs in the Zetia antitrust litigation, partially offset by the unfavorable effect of foreign exchange. Non-GAAP Expense, EPS and Related Information Non-GAAP gross margin was 80.8% for the fourth quarter of 2024 compared with 77.2% for the fourth quarter of 2023. Non-GAAP gross margin was 80.8% for the full year of 2024 compared with 76.9% for the full year of 2023. The non-GAAP gross margin improvements in both the fourth quarter and full year of 2024 were primarily due to the favorable effects of product mix (including lower royalty rates related to KEYTRUDA and GARDASIL/GARDASIL 9) and foreign exchange, partially offset by higher manufacturing-related costs (including inventory write-offs). Non-GAAP SG&A expenses were $2.8 billion in the fourth quarter of 2024, an increase of 2% compared with the fourth quarter of 2023. Non-GAAP SG&A expenses were $10.6 billion for the full year of 2024, an increase of 3% compared with the full year of 2023. The increases were primarily due to higher promotional and selling costs and, for the full year, higher administrative costs, partially offset by the favorable impact of foreign exchange. Non-GAAP R&D expenses were $4.6 billion in the fourth quarter of 2024, a decrease of 48% compared with the fourth quarter of 2023. Non-GAAP R&D expenses were $17.9 billion for the full year of 2024, a decrease of 40% compared with the full year of 2023. The declines in both the fourth quarter and full year of 2024 were primarily due to lower charges for business development activity and the favorable impact of foreign exchange, partially offset by increased compensation and benefit costs and higher clinical development spending. Non-GAAP other (income) expense, net, was $5 million of expense in the fourth quarter of 2024 compared with $174 million of expense in the fourth quarter of 2023. The favorability was primarily due to lower foreign exchange losses and lower net interest expense. Non-GAAP other (income) expense, net, was $10 million of expense in the full year of 2024 compared with $219 million of expense in the full year of 2023. The favorability was primarily due to $170 million of income related to the expansion of an existing development and commercialization agreement with Daiichi Sankyo, as well as lower foreign exchange losses in 2024, partially offset by higher net interest expense. The non-GAAP effective tax rate was 16.2% for the fourth quarter and 16.8% for the full year of 2024. Non-GAAP EPS was $1.72 for the fourth quarter of 2024 compared with $0.03 for the fourth quarter of 2023. Non-GAAP EPS was $7.65 for the full year of 2024 compared with EPS of $1.51 for the full year of 2023. The increase in both periods was primarily driven by lower charges for business development transactions and operational strength in the business. The unfavorable effect of foreign exchange partially offset the increase in the full year.

In oncology, Merck announced positive topline results from the pivotal Phase 3 MK-3475A-D77 trial evaluating the noninferiority of subcutaneous pembrolizumab and berahyaluronidase alfa, in combination with chemotherapy, versus intravenous (IV) KEYTRUDA administered with chemotherapy, for the first-line treatment of adult patients with metastatic NSCLC. Subcutaneous pembrolizumab and berahyaluronidase alfa has the potential to improve the patient experience and increase access for patients and health care providers compared to IV administration. Merck presented new data across multiple hematologic malignancies at the American Society of Hematology Annual Meeting and Exposition in December 2024, including promising Phase 2 data for its investigational antibody-drug conjugate zilovertamab vedotin for the treatment of patients with previously untreated diffuse large B-cell lymphoma. With more than 20 abstracts presented, the data showcased Merck’s continued progress in advancing clinical research for its expanding and diverse hematology pipeline. Merck also achieved several key regulatory milestones in the U.S., Europe, Japan and China. Highlights include the U.S. Food and Drug Administration (FDA) granting Breakthrough Therapy designation to sacituzumab tirumotecan (sac-TMT) for the treatment of certain patients with previously treated advanced or metastatic nonsquamous NSCLC with epidermal growth factor receptor (EGFR) mutations. Additionally, Merck received new approvals for KEYTRUDA-based regimens in Japan and China, as well as for WELIREG and Lynparza in China. In vaccines and infectious diseases, the FDA accepted the Biologics License Application (BLA) for clesrovimab, an investigational prophylactic long-acting monoclonal antibody designed to protect infants from respiratory syncytial virus (RSV) disease during their first RSV season and set a Prescription Drug User Fee Act (PDUFA) date of June 10, 2025. This regulatory milestone marks important progress toward having clesrovimab available in time for the 2025-26 RSV season. The filing was based on results from the pivotal Phase 2b/3 study of clesrovimab in infants for the prevention of RSV that was presented at ID Week 2024. In addition, Merck announced topline results from two pivotal Phase 3 trials of the investigational, once-daily, oral, two-drug, single-tablet regimen of doravirine/islatravir (DOR/ISL) in adults with virologically suppressed HIV-1 infection, in line with Merck’s commitment to help address the needs of people living with HIV. In January 2025, Merck also received expanded approval in China for GARDASIL. It is now the first HPV vaccine approved in China for the prevention of certain HPV-related cancers and diseases in males 9-26 years of age. In addition, the European Union’s (EU) Committee for Medicinal Products for Human Use (CHMP) recommended the approval of CAPVAXIVE for pneumococcal vaccination in adults, with a final decision for EU approval expected in the second quarter of 2025. In cardiovascular disease, Merck announced positive topline results from the Phase 3 ZENITH study, evaluating WINREVAIR in adults with pulmonary arterial hypertension (PAH) with World Health Organization (WHO) Group 1 functional class (FC) III or IV at high risk of mortality. Based on the positive results of an interim analysis, an independent data monitoring committee recommended that the study be stopped early due to overwhelming efficacy. In addition, in January 2025, Merck announced the Phase 3 HYPERION study evaluating WINREVAIR in newly diagnosed adults with PAH with FC II or III at intermediate or high risk of disease progression was also stopped early based on the positive results from the interim analysis of the ZENITH trial and a review of the totality of data from the WINREVAIR clinical program to date. All participants in both the ZENITH and HYPERION studies will be offered the opportunity to receive WINREVAIR as part of the open-label, long-term extension study, SOTERIA. Merck continued to execute on its business development strategy. The company announced the closing of an exclusive global license for MK-2010, a novel investigational PD-1/VEGF bispecific antibody from LaNova. Merck also entered into an exclusive global license agreement with Hansoh to evaluate MK-4082, an investigational preclinical oral small molecule glucagon-like peptide (GLP-1) receptor agonist.

Full Year 2025 Sales * $64.1 billion to $65.6 billion Non-GAAP Gross margin 2 Approximately 82.5% Non-GAAP Operating expenses 2** $25.4 billion to $26.4 billion Non-GAAP Other (income) expense, net 2 $300 million to $400 million expense Non-GAAP Effective tax rate 2 16.0% to 17.0% Non-GAAP EPS 2*** $8.88 to $9.03 Share count (assuming dilution) Approximately 2.53 billion *The company does not have any non-GAAP adjustments to sales. **Includes $300 million for an anticipated milestone payment to LaNova associated with the technology transfer for MK-2010 expected to be completed in 2025. Outlook does not assume any additional significant potential business development transactions. ***Includes expected one-time charge of approximately $0.09 per share related to the $300 million milestone payment to LaNova upon completion of the technology transfer for MK-2010. Merck has not provided a reconciliation of forward-looking non-GAAP gross margin, non-GAAP operating expenses, non-GAAP other (income) expense, net, non-GAAP effective tax rate and non-GAAP EPS to the most directly comparable GAAP measures, given it cannot predict with reasonable certainty the amounts necessary for such a reconciliation, including intangible asset impairment charges, legal settlements, and income and losses from investments in equity securities either owned directly or through ownership interests in investment funds, without unreasonable effort. These items are inherently difficult to forecast and could have a significant impact on the company’s future GAAP results. Merck anticipates full-year 2025 sales to be between $64.1 billion and $65.6 billion, including a negative impact of foreign exchange of approximately 2% at mid-January 2025 exchange rates. This sales range reflects a decision to temporarily pause shipments of GARDASIL/GARDASIL 9 into China beginning February 2025 through at least mid-year. Merck’s full-year non-GAAP effective income tax rate is expected to be between 16.0% and 17.0%. Merck expects full-year 2025 non-GAAP EPS to be between $8.88 and $9.03, including a negative impact of foreign exchange of approximately $0.35 per share. This range includes an expected one-time charge of $300 million, or approximately $0.09 per share, related to a milestone payment to LaNova, which will be recognized upon completion of the technology transfer for MK-2010. In 2024, non-GAAP EPS of $7.65 was negatively impacted by a net charge of $1.28 per share related to certain asset acquisitions, licensing agreements and collaborations. Consistent with past practice, the financial outlook does not assume additional significant potential business development transactions.

Management believes that providing this information enhances investors’ understanding of the company’s results because management uses non-GAAP results to assess performance. Management uses non-GAAP measures internally for planning and forecasting purposes and to measure the performance of the company along with other metrics. In addition, annual employee compensation, including senior management’s compensation, is derived in part using a non-GAAP pretax income metric. This information should be considered in addition to, but not as a substitute for or superior to, information prepared in accordance with GAAP. For a description of the non-GAAP adjustments, see Table 2a attached to this release. 3 Reflects expenses related to business combinations, including the amortization of intangible assets, intangible asset impairment charges, and expense or income related to changes in the estimated fair value measurement of liabilities for contingent consideration. Also includes integration, transaction and certain other costs associated with acquisitions and divestitures, as well as amortization of intangible assets related to collaborations and licensing arrangements. 4 Includes the estimated tax impacts on the reconciling items based on applying the statutory rate of the originating territory of the non-GAAP adjustments, as well as a $260 million benefit and a $519 million benefit in the fourth quarter and full year of 2024, respectively, due to reductions in reserves for unrecognized income tax benefits resulting from the expiration of the statute of limitations for assessments related to certain federal tax return years. The benefit recognized in the fourth quarter of 2024 relates to the 2020 federal tax return year and the benefit for the full year of 2024 relates to both the 2020 and 2019 federal tax return years.
