Third-Quarter Sales Performance The following table reflects sales of the Company’s top products and significant performance drivers. Third Quarter $ in millions 2025 2024 Change Change Ex-Exchange Commentary Total Sales $17,276 $16,657 4% 3% Pharmaceutical 15,611 14,943 4% 3% Increase primarily driven by growth in oncology, cardiovascular and diabetes, partially offset by declines in vaccines, virology and immunology. KEYTRUDA 8,142 7,429 10% 8% Growth driven by continued strong global demand from metastatic indications, including urothelial, endometrial and gastric cancers, as well as robust global uptake in earlier-stage indications including triple-negative breast cancer, cervical cancer, renal cell carcinoma (RCC) and non-small cell lung cancer (NSCLC). Sales also benefitted from timing of wholesaler purchases in the U.S., partially offset by other channel movements. GARDASIL/GARDASIL 9 1,749 2,306 -24% -25% Decline primarily due to lower demand in China. Excluding China, sales declined 2%, or 3% excluding impact of foreign exchange, reflecting lower demand in Japan following a national catch-up immunization program, partially offset by higher sales in the U.S. due to higher net pricing and favorable public-sector purchasing patterns. PROQUAD, M-M-R II and VARIVAX 684 703 -3% -3% Decline primarily due to lower demand, partially offset by higher net pricing in the U.S. JANUVIA/JANUMET 624 482 29% 29% Growth driven by higher net pricing in the U.S., partially offset by lower demand in China as well as in most other international markets due to generic competition. BRIDION 439 420 5% 4% Growth primarily due to higher demand in the U.S., partially offset by lower demand in most international markets due to ongoing generic competition. Lynparza* 379 337 12% 12% Growth primarily due to higher demand in the U.S. and certain international markets. WINREVAIR 360 149 141% 141% Growth largely reflects continued uptake in the U.S., partially offset by timing of distributor purchases and lower net pricing in the U.S. largely due to Medicare Part D redesign. PREVYMIS 266 208 28% 25% Increase primarily due to higher demand in the U.S. and launch of new indications in certain international markets, partially offset by lower demand in China due to generic competition. Lenvima* 258 251 3% 2% Increase primarily due to higher sales in the U.S. reflecting higher demand, partially offset by lower net pricing. CAPVAXIVE 244 47 N/M N/M Represents continued uptake since third-quarter 2024 launch in the U.S., as well as expected seasonal inventory build. VAXNEUVANCE 226 239 -6% -7% Decline primarily due to lower demand in certain international markets, particularly in Japan due to competitive pressure, partially offset by higher demand in certain European markets. WELIREG 196 139 42% 41% Growth primarily driven by higher demand in the U.S. and continued launch uptake in certain European markets, partially offset by lower net pricing in the U.S. LAGEVRIO 138 383 -64% -65% Decline primarily due to lower demand in the Asia Pacific region, particularly in Japan, as well as in the U.S. SIMPONI - 189 -100% -100% Marketing rights in former territories of the Company reverted to Johnson & Johnson on Oct. 1, 2024. Animal Health 1,615 1,487 9% 7% Growth primarily due to performance of livestock products. Livestock 1,023 886 16% 14% Growth primarily driven by higher demand across all species, as well as timing of sales. Companion Animal 592 601 -2% -3% Decline primarily due to lower demand, reflecting a reduction in veterinary visits and competitive pressure for parasiticides, partially offset by higher pricing, improved supply and new product launches. Sales of BRAVECTO were $262 million and $266 million in current and prior-year quarters, respectively, which represents a decline of 1%, or 3% excluding impact of foreign exchange. Other Revenues** 50 227 -78% -27% Decline primarily due to unfavorable impact of revenue-hedging activities and lower revenue from third-party manufacturing arrangements. *Alliance revenue for this product represents the Company’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. N/M- Not meaningful. In addition, Koselugo alliance revenue was $214 million in the third quarter of 2025 compared with $39 million in the third quarter of 2024. The increase was due to an amendment to the collaboration agreement with AstraZeneca, which discontinued the provisions whereby the Company shared revenue and costs with AstraZeneca, and revised the payment structure, resulting in the Company’s recognition of a $150 million upfront payment and a $50 million regulatory milestone. Third-Quarter Expense, EPS and Related Information The table below presents selected expense information. $ in millions GAAP Acquisition- and Divestiture- Related Costs3 Restructuring Costs (Income) Loss From Investments in Equity Securities Non-GAAP2 Third Quarter 2025 Cost of sales $3,855 $621 $110 $- $3,124 Selling, general and administrative 2,633 34 - - 2,599 Research and development 4,234 4 233 - 3,997 Restructuring costs 47 - 47 - - Other (income) expense, net (238) - - (344) 106 Third Quarter 2024 Cost of sales $4,080 $639 $192 $- $3,249 Selling, general and administrative 2,731 43 31 - 2,657 Research and development 5,862 24 - - 5,838 Restructuring costs 56 - 56 - - Other (income) expense, net (162) (27) - 58 (193) GAAP Expense, EPS and Related Information Gross margin was 77.7% for the third quarter of 2025 compared with 75.5% for the third quarter of 2024. The increase was primarily due to the favorable impact of product mix and lower restructuring costs, partially offset by higher inventory write-offs and the unfavorable impact of foreign exchange. Selling, general and administrative (SG&A) expenses were $2.6 billion in the third quarter of 2025, a decrease of 4% compared with the third quarter of 2024. The decrease was primarily due to lower administrative, restructuring and selling costs, partially offset by the unfavorable impact of foreign exchange. Research and development (R&D) expenses were $4.2 billion in the third quarter of 2025, a decrease of 28% compared with the third quarter of 2024. The decrease was primarily due to lower charges for business development activity, including charges of $2.2 billion in the aggregate related to the acquisitions of EyeBio and MK-1045 in the third quarter of 2024, compared with a charge of $300 million in the third quarter of 2025 related to a milestone payment to LaNova for the completion of the technology transfer for MK-2010. Excluding these charges, R&D expenses increased primarily due to higher restructuring costs and clinical development spending. Other (income) expense, net, was $238 million of income in the third quarter of 2025 compared with $162 million of income in the third quarter of 2024. The favorability was primarily due to net income from investments in equity securities in 2025 compared with net losses from investments in equity securities in 2024, partially offset by $170 million of income recognized in 2024 related to a payment received from Daiichi Sankyo associated with the expansion of an existing development and commercialization agreement to include gocatamig (MK-6070). The effective tax rate was 14.2% for the third quarter of 2025. GAAP EPS was $2.32 for the third quarter of 2025 compared with $1.24 for the third quarter of 2024. The increase was primarily driven by a net charge of $0.79 per share in the aggregate in 2024 for the EyeBio, Curon and Daiichi Sankyo transactions, partially offset by a charge of $0.10 per share in 2025 related to the LaNova technology transfer milestone payment. Non-GAAP Expense, EPS and Related Information Non-GAAP gross margin was 81.9% for the third quarter of 2025 compared with 80.5% for the third quarter of 2024. The increase was primarily due to the favorable impact of product mix, partially offset by higher inventory write-offs and the unfavorable impact of foreign exchange. Non-GAAP SG&A expenses were $2.6 billion in the third quarter of 2025, a decrease of 2% compared with the third quarter of 2024. The decrease was primarily due to lower administrative and selling costs, partially offset by the unfavorable impact of foreign exchange. Non-GAAP R&D expenses were $4.0 billion in the third quarter of 2025, a decrease of 32% compared with the third quarter of 2024. The decrease was primarily due to lower charges for business development activity, including charges of $2.2 billion in the aggregate related to the acquisitions of EyeBio and MK-1045 in the third quarter of 2024, compared with a charge of $300 million in the third quarter of 2025 related to a milestone payment to LaNova for the completion of the technology transfer for MK-2010. Excluding these charges, R&D expenses increased primarily due to higher clinical development spending. Non-GAAP other (income) expense, net, was $106 million of expense in the third quarter of 2025 compared with $193 million of income in the third quarter of 2024. The unfavorability was primarily due to $170 million of income recognized in 2024 related to a payment received from Daiichi Sankyo associated with the expansion of an existing development and commercialization agreement to include gocatamig (MK-6070). The non-GAAP effective tax rate was 13.4% for the third quarter of 2025. Non-GAAP EPS was $2.58 for the third quarter of 2025 compared with $1.57 for the third quarter of 2024. The increase was primarily driven by a net charge of $0.79 per share in the aggregate in 2024 for the EyeBio, Curon and Daiichi Sankyo transactions, partially offset by a charge of $0.10 per share in 2025 related to the LaNova technology transfer milestone payment.

In oncology, in September 2025, the U.S. Food and Drug Administration (FDA) approved KEYTRUDA QLEX injection for subcutaneous (SC) administration for use in adults across most solid tumor indications for KEYTRUDA, based on results from the Phase 3 MK-3475A-D77 trial. In October 2025, the FDA subsequently approved KEYTRUDA QLEX for the treatment of certain adult patients with resectable locally advanced head and neck squamous cell carcinoma (LA-HNSCC), based on results from the Phase 3 KEYNOTE-689 trial. KEYTRUDA QLEX is now approved for use in adults across all solid tumor indications approved for KEYTRUDA and is the first and only subcutaneously administered immune checkpoint inhibitor that can be given by a health care provider in as little as one minute. In addition, the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending approval for SC administration of KEYTRUDA for all adult indications; a final decision is expected in the fourth quarter of 2025. The European Commission (EC) also approved KEYTRUDA as part of a perioperative regimen for the treatment of PD-L1+ resectable LA-HNSCC. At the European Society for Medical Oncology (ESMO) Congress 2025, the Company announced new research from its broad and differentiated portfolio and pipeline, highlighting progress in new tumor types and earlier stages of disease. This included positive results from the Phase 3 KEYNOTE-905 trial (also known as EV-303) in cisplatin-ineligible patients with muscle-invasive bladder cancer (MIBC), the Phase 3 KEYNOTE-B96 trial in platinum-resistant recurrent ovarian cancer and the Phase 2/3 REJOICE-Ovarian01 trial in collaboration with Daiichi Sankyo in certain types of platinum-resistant ovarian cancer, long-term follow-up data from the Phase 3 KEYNOTE-775 trial in advanced endometrial cancer, as well as long-term data for KEYTRUDA in both earlier-stage and metastatic NSCLC. In vaccines and infectious diseases, in August 2025, the Company received two approvals in Japan: its nine-valent HPV vaccine for use in males ages 9 and older that will be marketed under the trademark SILGARD 9, and CAPVAXIVE for use in the elderly or adults who are at an increased risk of pneumococcal disease. At the European AIDS Clinical Society 2025 conference, the Company also presented new data from Phase 3 trials evaluating the once-daily, oral, two-drug regimen of doravirine/islatravir in adults with virologically suppressed HIV-1 infection, which showed minimal changes in weight and body composition and no clinically meaningful effect on fasting lipids and the homeostatic model assessment of insulin resistance across both clinical trials. In cardiovascular disease, the Company announced positive topline results from the Phase 3 CORALreef Lipids trial evaluating the safety and efficacy of enlicitide decanoate, an investigational, once-daily oral proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor being evaluated for the treatment of adults with hypercholesterolemia. The trial met all primary and key secondary endpoints. Enlicitide has the potential to be the first approved oral PCSK9 inhibitor. In addition, the FDA approved an update to the U.S. product label for WINREVAIR, based on results from the Phase 3 ZENITH trial, expanding the indication to include components of the clinical worsening events: hospitalization for pulmonary arterial hypertension (PAH), lung transplantation and death. Further, at the 2025 European Respiratory Society Congress, the Company presented positive results from the Phase 3 HYPERION trial evaluating WINREVAIR versus placebo (both in combination with background therapy) in adults recently diagnosed with PAH (Group 1 pulmonary hypertension) with World Health Organization (WHO) functional class II or III at intermediate or high risk of disease progression. Results showed that adding WINREVAIR within the first year after PAH diagnosis significantly reduced the risk of clinical worsening events compared to placebo. The Company also completed its acquisition of Verona Pharma plc (Verona Pharma) in October 2025, strengthening its cardio-pulmonary portfolio with the addition of OHTUVAYRE, an FDA-approved, first-in-class maintenance treatment for chronic obstructive pulmonary disease (COPD) in adult patients.

Manufacturing and R&D Investment The Company continued to make long-term investments in its U.S. manufacturing and R&D capabilities and broke ground on a new $3 billion Center of Excellence for Pharmaceutical Manufacturing at its Elkton, Virginia site. The 400,000-square-foot facility will include both active pharmaceutical ingredient and drug product investment to support small molecule manufacturing and testing, creating more than 500 full-time jobs. This investment is part of the Company’s commitment to dedicate more than $70 billion beginning in 2025 to expand domestic manufacturing and R&D — not including any future business development in R&D — to drive its long-term growth and strengthen the U.S. as a global leader in biopharmaceutical innovation. Upcoming Investor Event The Company also plans to present new data from its innovative cardiovascular pipeline and portfolio at the American Heart Association (AHA) Scientific Sessions 2025 from Nov. 7-10. The Company will host an Investor Event to coincide with the AHA Scientific Sessions 2025 on Sunday, Nov. 9 at 6 p.m. CT. The event will take place in New Orleans and will be accessible via live audio webcast at this weblink. Sustainability Highlights The Company’s 2024/2025 Purpose for Progress Impact Report provided a comprehensive view of how it is pursuing innovative science for the health of people and animals and ensuring its efforts drive significant and sustainable value. The report noted that the Company’s medicines and vaccines reached more than 450 million people around the world in 2024. Full-Year 2025 Financial Outlook The following table summarizes the Company’s full-year financial outlook. Full Year 2025 Updated Prior Sales* $64.5 billion to $65.0 billion $64.3 billion to $65.3 billion Non-GAAP Gross margin2 Approximately 82% Approximately 82% Non-GAAP Operating expenses2(a) $25.9 billion to $26.4 billion $25.6 billion to $26.4 billion Non-GAAP Other (income) expenses, net2 $400 million to $500 million expense $300 million to $400 million expense Non-GAAP Effective tax rate2 14.0% to 15.0% 15.0% to 16.0% Non-GAAP EPS2(b)(c) $8.93 to $8.98 $8.87 to $8.97 Share count (assuming dilution) Approximately 2.51 billion Approximately 2.51 billion *The Company does not have any non-GAAP adjustments to sales. (a)Includes one-time R&D charges of $300 million for a milestone payment to LaNova associated with the technology transfer for MK-2010 and $200 million for an upfront payment for a license agreement with Jiangsu Hengrui Pharmaceuticals Co., Ltd. (Hengrui Pharma). Outlook does not assume any additional significant potential business development transactions. (b)Includes one-time charges totaling $0.16 per share associated with the payment for the LaNova technology transfer for MK-2010 and the upfront payment to Hengrui Pharma. (c)Updated full-year 2025 outlook reflects a benefit of approximately $0.09 per share resulting from an amendment to the collaboration agreement with AstraZeneca related to Koselugo, and an estimated negative impact of $0.04 per share related to the acquisition of Verona Pharma. The Company 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. The Company now expects full-year 2025 sales to be between $64.5 billion and $65.0 billion, including a negative impact of foreign exchange of approximately 0.5% at mid-October 2025 exchange rates. The Company now expects its full-year non-GAAP effective income tax rate to be between 14.0% and 15.0%. The Company now expects its full-year non-GAAP EPS to be between $8.93 and $8.98, including a negative impact of foreign exchange of approximately $0.15 per share. This revised non-GAAP EPS outlook reflects several items not previously included, such as a benefit from an amended collaboration agreement with AstraZeneca related to Koselugo, and operational improvements, including a more favorable estimated tax rate and lower estimated costs related to the impact of tariffs, partially offset by an estimated negative impact related to the acquisition of Verona Pharma and an incremental negative impact from foreign exchange. The midpoint of this revised non-GAAP EPS range reflects a net improvement of $0.04 per share compared to the midpoint of the Company’s prior outlook. As previously communicated, the revised estimated full-year 2025 non-GAAP EPS range reflects the impacts of the one-time charges in connection with a license agreement with Hengrui Pharma and the completion of the technology transfer with LaNova for MK-2010, which impact EPS by approximately $0.16 in the aggregate. 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.

IFRS gross profit margin reached 41.0%, with an adjusted gross profit margin of 45.4%. The increase in gross profit and margin was primarily due to the efficiency improvements driven from WBS and digitalization, and also the improvements of the ramp-up impacts from the recently commissioned facilities in Europe and the U.S. as expected. EBITDA and EBITDA Margin: For the year ended December 31, 2024, EBITDA grew 16.7% to RMB6,547.8 million, while adjusted EBITDA increased 14.4% YoY to RMB7,999.3 million. EBITDA margin reached 35.1%, with an adjusted EBITDA margin of 42.8%. Net Profit and Net Profit Attributable to Owners of the Company: IFRS net profit rose 10.5% YoY to RMB3,945.4 million. Net profit attributable to owners of the Company was RMB3,356.1 million, reflecting a slight YoY decline of 1.3%. Adjusted Net Profit: Adjusted Net Profit for the period increased 9.0% YoY to RMB5,396.9 million. Adjusted net profit margin was 28.9%. Basic Earnings Per Share (EPS): The Group's basic earnings per share (EPS) remained flat at RMB 0.82 for the years ended December 31, 2024 and 2023. Diluted EPS slightly increased by 1.3% from RMB 0.77 for the year ended December 31, 2023 to RMB 0.78 for the year ended December 31, 2024. Business Highlights Integrated Project Wins The Group added 151 integrated projects in 2024, bringing the total to 817. Notably, over half of the new projects originated from U.S. clients, reflecting strong client trusts and the Group's resilience amid a dynamic environment. The Group supported 66 Phase III projects and 21 non-COVID commercial projects, strengthening its manufacturing pipeline. During the Reporting Period, the Group continued to execute its "Win-the-Molecule" strategy, securing 20 post-IND projects, including 13 in late-phase and commercial stage, bringing total wins to 89 since 2018. Research By leveraging industry-leading technology platforms, the Group's Research business has reached an inflection point following years of strategic cultivation. The Group has developed a portfolio of leading Immune Cell Engager (ICE) technologies, extending beyond traditional T-cell engagers (TCEs). Our diverse immune cell-targeting modalities—including CD3 Bispecific T Cell Engagers, Non-cytotoxic T Cell Engagers, γδ T Cell Engagers, NK Engagers, and Macrophage Engagers—are designed to unlock novel therapeutic potential in oncology and autoimmune diseases. The Group is advancing these innovations in close collaboration with its clients and partners, driving the development of next-generation anti-tumor and autoimmune therapies. In 2024, the Group enabled seven global programs for molecule discovery and is eligible to receive approximately $140 million in near-term payments, with total potential payments exceeding $2.3 billion. To date, the Group's Research Services has enabled 50+ programs that are potentially eligible for future milestone payments and sales royalties, establishing a consistent revenue and profit stream. Development The Group added 148 new development projects in 2024, further strengthening one of the industry's largest portfolios of complex biologics. This portfolio includes 151 bispecifics & multispecifics, 194 ADCs, 80 fusion proteins and 24 vaccines. The Group continues to advance cutting-edge technology platforms that accelerate biologics development and manufacturing.
