Excluding LAGEVRIO and impact of foreign exchange, growth of 14%. KEYTRUDA 6,608 5,450 21% 22% Growth driven by increased global uptake in earlier-stage indications, including triple-negative breast cancer and renal cell carcinoma (RCC), and continued strong global demand from metastatic indications. GARDASIL/GARDASIL 9 1,871 1,470 27% 27% Growth due to strong global demand, particularly in China, and public-sector buying patterns in the U.S. JANUVIA/JANUMET 787 913 -14% -13% Decline primarily due to generic competition in several international markets, particularly in Europe, and lower demand in the U.S. PROQUAD, M-M-R II and VARIVAX 545 526 4% 3% Growth largely due to higher pricing in the U.S. BRIDION 429 441 -3% -3% Decline primarily due to generic competition in certain ex-U.S. markets, particularly in Europe, partially offset by higher demand in the U.S. Lynparza* 315 292 8% 8% Growth driven primarily by higher pricing in the U.S. Lenvima* 226 216 5% 5% Growth primarily due to higher demand in the U.S., partially offset by timing of shipments in China. LAGEVRIO 193 825 -77% -76% Decline due to nonrecurrence of sales in the U.K. and lower demand in Japan and Australia. ROTATEQ 185 139 34% 33% Growth primarily due to public-sector buying patterns in the U.S. and timing of shipments in China. VAXNEUVANCE 176 138 28% 26% Growth largely driven by launches in Europe and continued uptake for the pediatric indication in the U.S. Prior-year quarter benefited from inventory stocking in the U.S. in preparation for pediatric launch. Animal Health 1,278 1,230 4% 4% Growth primarily driven by higher demand for Companion Animal products. Livestock 808 814 -1% 0% Decline primarily due to timing of shipments for ruminant products, largely offset by higher pricing across the product portfolio and higher demand for swine products. Companion Animal 470 416 13% 12% Growth primarily due to higher demand and timing of shipments for BRAVECTO line of products, as well as higher pricing. Sales of BRAVECTO were $197 million and $168 million in the current and prior-year quarters, respectively, which represented growth of 18%, or 19% excluding the impact of foreign exchange. Other Revenues** 211 420 -50% -1% Decline primarily due to impact of revenue hedging activities. *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 Revenue Performance The following table reflects sales of the company’s top pharmaceutical products, as well as sales of Animal Health products.

N/M - Not meaningful Full-year 2023 pharmaceutical sales grew 3% to $53.6 billion. Pharmaceutical sales growth was primarily driven by higher sales in oncology, particularly KEYTRUDA, higher sales of vaccines, reflecting strong growth of combined sales of GARDASIL/GARDASIL 9 and VAXNEUVANCE, as well as growth in hospital acute care products, including PREVYMIS and BRIDION. Pharmaceutical sales growth in 2023 was partially offset by lower sales of the COVID-19 medication LAGEVRIO, as well as lower sales of JANUVIA and JANUMET, primarily reflecting generic competition in many ex-U.S. markets and lower demand in the U.S., and lower sales of PNEUMOVAX 23 as the market continues to shift toward newer adult pneumococcal conjugate vaccines. Pharmaceutical sales growth for the full year of 2023 was 14% excluding LAGEVRIO and the unfavorable impact of foreign exchange. Full-year 2023 Animal Health sales grew 1% to $5.6 billion. Excluding the unfavorable impact of foreign exchange, Animal Health sales grew 3%, primarily due to higher pricing. Full-year sales growth was also driven by higher demand for livestock products, led by poultry and swine products, partially offset by lower demand for ruminant products. Sales of BRAVECTO were $1.1 billion in 2023, which represented growth of 4%, or 5% excluding the impact of foreign exchange, primarily reflecting higher pricing.

The increase was primarily due to the favorable impacts of lower LAGEVRIO sales, which have a low gross margin, lower manufacturing facilities costs and product mix, partially offset by the unfavorable impacts of foreign exchange and higher restructuring costs. Gross margin was 73.2% for the full year of 2023 compared with 70.6% for the full year of 2022. The increase was primarily due to the favorable impacts of lower LAGEVRIO sales, product mix, lower manufacturing facilities costs, and lower revenue from third-party manufacturing arrangements, partially offset by the unfavorable impact of foreign exchange. Selling, general and administrative (SG&A) expenses were $2.8 billion in the fourth quarter of 2023, an increase of 4% compared with the fourth quarter of 2022. The increase was primarily due to higher administrative costs, including higher compensation and benefit costs, partially offset by lower promotional spending. Full-year 2023 SG&A expenses were $10.5 billion, an increase of 5% compared with the full year of 2022. The increase was primarily due to higher administrative costs, including higher compensation and benefit costs, and higher promotional spending, partially offset by the favorable impact of foreign exchange and lower acquisition- and divestiture-related costs. R&D expenses were $9.6 billion in the fourth quarter of 2023 compared with $3.8 billion in the fourth quarter of 2022. R&D expenses were $30.5 billion for the full year of 2023 compared with $13.5 billion for the full year of 2022. The increase in the fourth quarter and full year of 2023 reflects a $5.5 billion charge for the collaboration with Daiichi Sankyo, and higher development costs due to spending on clinical programs, including newly acquired programs, as well as higher compensation and benefit costs (reflecting in part increased headcount). The increase in R&D expenses for the full year was also due to charges of $11.4 billion in the aggregate for the acquisitions of Prometheus Biosciences, Inc. (Prometheus) and Imago BioSciences, Inc. (Imago). The increase in R&D expenses for the full year was partially offset by lower intangible asset impairment charges in 2023 and charges of $690 million in the aggregate in 2022 for collaboration and licensing agreements with Moderna, Inc. (Moderna), Orna Therapeutics (Orna) and Orion Corporation (Orion). Other (income) expense, net, was $78 million of expense in the fourth quarter of 2023 compared with $75 million of income in the fourth quarter of 2022, primarily due to higher exchange losses and higher net interest expense, partially offset by net gains from investments in equity securities for the fourth quarter of 2023 compared with net losses from investments in equity securities for the fourth quarter of 2022, and lower pension settlement costs. Other (income) expense, net, was $466 million of expense in the full year of 2023 compared with $1.5 billion of expense in the full year of 2022, primarily due to net gains from investments in equity securities in 2023 compared with net losses from investments in equity securities in 2022, and lower pension settlement costs, partially offset by a $572.5 million charge in 2023 related to settlements with certain plaintiffs in the Zetia antitrust litigation. The effective tax rate was 40.1% for the fourth quarter of 2023 compared with 14.1% in the fourth quarter of 2022. The effective tax rate for the fourth quarter of 2023 includes a 29.2 percentage point impact resulting from the charge for the Daiichi Sankyo collaboration. The effective tax rate was 80.0% for the full year of 2023 compared with 11.7% for the full year of 2022. The full-year 2023 effective tax rate reflects an aggregate 65.6 percentage point unfavorable impact, resulting from charges for asset acquisitions (for which no tax benefits were recognized) as well as the charge for the Daiichi Sankyo collaboration. GAAP loss per share was $0.48 for the fourth quarter of 2023 compared with EPS of $1.18 for the fourth quarter of 2022, primarily driven by the charge in 2023 related to the collaboration with Daiichi Sankyo, the unfavorable impact of foreign exchange and higher restructuring costs, partially offset by a beneficial impact from the tax rate and operational strength in the business. GAAP EPS was $0.14 for the full year of 2023 compared with EPS of $5.71 for the full year of 2022. The EPS decline in 2023 was primarily due to higher charges for certain business development transactions, the unfavorable impact of foreign exchange and the tax rate, as well as a charge related to settlements with certain plaintiffs in the Zetia antitrust litigation, partially offset by the beneficial impacts of operational strength in the business, better performance from equity investments and lower intangible asset impairment charges. Non-GAAP Expense, EPS and Related Information Non-GAAP gross margin was 77.2% for the fourth quarter of 2023 compared with 75.7% for the fourth quarter of 2022. Non-GAAP gross margin was 76.9% for the full year of 2023 compared with 74.4% for the full year of 2022. The non-GAAP gross margin improvement in the fourth quarter and full year of 2023 was primarily due to the favorable impacts of lower LAGEVRIO sales, which have a low gross margin, product mix, and lower manufacturing facilities costs. The increase in non-GAAP gross margin for the full year was also due to lower revenue from third-party manufacturing arrangements. The non-GAAP gross margin improvement in the fourth quarter and full year of 2023 was partially offset by the unfavorable impact of foreign exchange. Non-GAAP SG&A expenses were $2.8 billion for the fourth quarter of 2023 compared with $2.6 billion for the fourth quarter of 2022. The increase was primarily due to higher administrative costs, including higher compensation and benefit costs, partially offset by lower promotional spending. Full-year 2023 non-GAAP SG&A expenses were $10.3 billion, an increase of 5% compared with the full year of 2022. The increase was primarily due to higher administrative costs, including higher compensation and benefit costs, and higher promotional spending, partially offset by the favorable impact of foreign exchange. Non-GAAP R&D expenses were $8.8 billion in the fourth quarter of 2023 compared with $3.0 billion in the fourth quarter of 2022. Non-GAAP R&D expenses were $29.7 billion for the full year of 2023 compared with $11.8 billion for the full year of 2022. The increase in the fourth quarter and full year of 2023 reflects a $5.5 billion charge for the collaboration with Daiichi Sankyo, and higher development costs due to spending on clinical programs, including newly acquired programs, as well as higher compensation and benefit costs (reflecting in part increased headcount). The increase in non-GAAP R&D expenses for the full year was also due to charges of $11.4 billion in the aggregate for the acquisitions of Prometheus and Imago. The increase in R&D expenses for the full year was partially offset by charges of $690 million in the aggregate in 2022 for collaboration and licensing agreements with Moderna, Orna and Orion. Non-GAAP other (income) expense, net, was $174 million of expense in the fourth quarter of 2023 compared with $86 million of income in the fourth quarter of 2022, primarily due to higher exchange losses and higher net interest expense, partially offset by lower pension settlement costs. Non-GAAP other (income) expense, net, was $219 million of expense in the full year of 2023 compared with $360 million of expense in the full year of 2022, primarily due to lower pension settlement costs. The non-GAAP effective tax rate was 114.2% for the fourth quarter of 2023 compared with 15.6% in the fourth quarter of 2022. The non-GAAP effective tax rate for the fourth quarter of 2023 includes a 101.1 percentage point unfavorable impact resulting from the charge for the Daiichi Sankyo collaboration. The non-GAAP effective tax rate was 35.8% for the full year of 2023 compared with 14.2% for the full year of 2022. The full-year 2023 non-GAAP effective tax rate reflects an aggregate 21.2 percentage point unfavorable impact, resulting from charges for asset acquisitions (for which no benefits were recognized) as well as the charge for the Daiichi Sankyo collaboration. Non-GAAP EPS was $0.03 for the fourth quarter of 2023 compared with $1.62 for the fourth quarter of 2022. The non-GAAP EPS decline in the fourth quarter was primarily due to the charge in 2023 related to the collaboration with Daiichi Sankyo and the unfavorable impact of foreign exchange, partially offset by a beneficial impact from the tax rate and operational strength in the business. Non-GAAP EPS was $1.51 for the full year of 2023 compared with $7.48 for the full year of 2022. The non-GAAP EPS decline for the full year was primarily due to higher charges for certain business development transactions, the unfavorable impact of foreign exchange and the tax rate, partially offset by operational strength in the business.

The company recorded charges in its GAAP results of $190 million related to the 2024 Restructuring Program for the fourth quarter and full year of 2023. Pipeline and Portfolio Highlights In the fourth quarter, Merck continued to make significant progress advancing its broad portfolio and pipeline across key therapeutic areas, representing continued momentum toward addressing patient needs. In oncology, Merck received multiple U.S. Food and Drug Administration (FDA) approvals, including KEYTRUDA plus Padcev for the first-line treatment of adult patients with locally advanced or metastatic urothelial cancer and WELIREG for the treatment of certain patients with previously treated advanced RCC, among other approvals. The FDA also accepted and granted Priority Review to Merck and Daiichi Sankyo’s Biologics License Application (BLA) for patritumab deruxtecan for the treatment of certain patients with previously treated locally advanced or metastatic EGFR-mutated non-small cell lung cancer (NSCLC). The FDA set a Prescription Drug User Fee Act (PDUFA), or target action, date of June 26, 2024. In addition, Merck showed meaningful progress in its robust oncology pipeline, initiating Phase 3 trials for four investigational medicines, including bomedemstat (LSD1 inhibitor), nemtabrutinib (BTK inhibitor), MK-2870 (anti-TROP2 antibody-drug conjugate) and MK-5684 (CYP11A1 inhibitor). In vaccines, Merck received Priority Review from the FDA for a BLA for V116, the company’s investigational, 21-valent pneumococcal conjugate vaccine specifically designed to protect adults, based on results from multiple Phase 3 trials. The FDA set a PDUFA date of June 17, 2024. If approved, V116 would be the first pneumococcal conjugate vaccine to include serotypes responsible for approximately 83 percent of adult invasive pneumococcal disease in individuals 65 and older, according to U.S. Centers for Disease Control and Prevention data from 2018-2021. In hospital acute care, the European Commission (EC) approved PREVYMIS for prevention of cytomegalovirus (CMV) disease in high-risk adult kidney transplant recipients and extended 200-day dosing in adult hematopoietic stem cell transplant (HSCT) recipients who are at high risk for late CMV infection and disease. Merck continued to augment its pipeline through business development, and in January 2024, entered into a definitive agreement to acquire Harpoon Therapeutics, Inc. (Harpoon), for an approximate total equity value of $680 million, further diversifying its oncology pipeline. Notable recent news releases on Merck’s pipeline and portfolio are provided in the table that follows.

Full Year 2024 Sales * $62.7 to $64.2 billion Non-GAAP gross margin 2 Approximately 80.5% Non-GAAP operating expenses 2** $25.1 to $26.1 billion Non-GAAP other (income) expense, net 2 Approximately $200 million expense Non-GAAP effective tax rate 2 14.5% to 15.5% Non-GAAP EPS 2*** $8.44 to $8.59 Share count (assuming dilution) Approximately 2.54 billion *The company does not have any non-GAAP adjustments to sales. **Includes approximately $650 million of R&D expense related to the recently announced Harpoon acquisition, which is expected to close in the first half of 2024. Outlook does not assume any additional significant potential business development transactions. ***Includes a one-time charge of approximately $0.26 per share related to the Harpoon acquisition. 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 2024 sales to be between $62.7 billion and $64.2 billion, including a negative impact of foreign exchange of approximately 2% at mid-January 2024 exchange rates. The negative impact is primarily due to the devaluation of the Argentine peso, which the company expects will largely be offset by inflation-related price increases, consistent with market practice. The outlook for operating expenses reflects incremental R&D spending expected to be incurred to advance the development of promising programs related to the acquisitions of Prometheus, Imago and Harpoon, as well as the collaborations with Daiichi Sankyo and Kelun-Biotech. Merck’s full-year non-GAAP effective income tax rate is expected to be between 14.5% and 15.5%. Merck expects full-year 2024 non-GAAP EPS to be between $8.44 and $8.59, including a negative impact of foreign exchange of approximately $0.25 per share. In 2023, non-GAAP EPS of $1.51 was negatively impacted by charges of $6.21 per share related to certain acquisitions and collaboration agreements. In early January 2024, Merck announced the acquisition of Harpoon, which is expected to close in the first half of 2024, and result in a non-tax deductible charge of approximately $650 million of R&D expense included in non-GAAP results. The impact of the transaction on expected full-year non-GAAP EPS is approximately $0.26 per share, which is included in the 2024 outlook. Consistent with past practice, the financial outlook does not assume additional significant potential business development transactions.

Cardiovascular pipeline highlights Merck announced positive results from its pivotal Phase 3 STELLAR trial evaluating sotatercept, the company’s investigational activin receptor type IIA-Fc fusion protein, as an add-on to stable background therapy for the treatment of adults with pulmonary arterial hypertension. The trial met its primary efficacy outcome measure, demonstrating a statistically significant and clinically meaningful improvement in six-minute walk distance (6MWD) from baseline at 24 weeks, and eight out of nine secondary efficacy outcome measures, including the outcome measure of proportion of participants achieving multicomponent improvement [defined as improvement in 6MWD, improvement in N-terminal pro-B-type natriuretic peptide level, and either improvement in WHO Functional Class (FC) or maintenance of WHO FC II] and the outcome measure of time to death or the first occurrence of a clinical worsening event. The Cognitive/Emotional Impacts domain score of PAH-SYMPACT®, which was assessed as the ninth and final secondary outcome measure, did not achieve statistical significance. Results will be presented at an upcoming scientific congress. Merck received a Fast Track designation from the U.S. Food and Drug Administration (FDA) for MK-2060, an investigational anticoagulant therapy for the reduction in risk of major thrombotic cardiovascular events in patients with end-stage renal disease. Oncology program highlights Merck announced clinical trial results for KEYTRUDA (pembrolizumab), the company’s anti-PD-1 therapy, and Lynparza (olaparib), an oral poly (ADP-ribose) PARP inhibitor being co-developed and co-commercialized with AstraZeneca, at the European Society for Medical Oncology Congress 2022, including: Five-year overall survival (OS) data from the pivotal Phase 3 KEYNOTE-189 trial (KEYTRUDA plus pemetrexed and either cisplatin or carboplatin) in patients with metastatic nonsquamous non-small cell lung cancer (NSCLC) and the Phase 3 KEYNOTE-407 trial (KEYTRUDA plus carboplatin-paclitaxel or nab-paclitaxel) in patients with metastatic squamous NSCLC. In collaboration with Seagen and Astellas, the first presentation of data from Cohort K of the Phase 1b/2 EV-103/KEYNOTE-869 trial evaluating Padcev (enfortumab vedotin-ejfv) in combination with KEYTRUDA as first-line treatment for patients with cisplatin-ineligible unresectable locally advanced or metastatic urothelial cancer. Seven-year OS data from the Phase 3 SOLO-1 trial evaluating Lynparza as maintenance treatment in patients with advanced BRCA-mutated ovarian cancer, following first-line platinum-based chemotherapy, and final OS results from the Phase 3 PAOLA-1 trial evaluating Lynparza in combination with bevacizumab as maintenance treatment in patients with advanced ovarian cancer who were without evidence of disease after surgery or following response to platinum-based chemotherapy. The results of both trials were clinically meaningful in certain types of patients, but did not reach statistical significance. Merck announced that KEYTRUDA received four new approvals in Japan; KEYTRUDA is now approved in Japan for 23 uses in 11 different types of cancer, plus microsatellite instability-high (MSI-H) and tumor mutational burden-high solid tumors. Merck announced the following regulatory milestones for Lynparza: Priority review granted by the FDA for a supplemental New Drug Application for Lynparza in combination with abiraterone and prednisone or prednisolone for patients with metastatic castration-resistant prostate cancer (mCRPC), based on results from the Phase 3 PROpel trial. The Prescription Drug User Fee Act (PDUFA) date is in the fourth quarter of 2022. Approved in the European Union (EU) and Japan as adjuvant treatment for patients with germline BRCA-mutated, HER2-negative high-risk early breast cancer, based on results from the Phase 3 OlympiA trial. Approved in China as first-line maintenance treatment with bevacizumab for patients with homologous recombination deficient-positive advanced ovarian cancer, based on results from the Phase 3 PAOLA-1 trial. Merck provided updates on three Phase 3 trials: KEYNOTE-412, KEYNOTE-921 and LEAP-002. Vaccines program highlights Merck announced European Commission approval of an expanded indication for VAXNEUVANCE (Pneumococcal 15-valent Conjugate Vaccine) to include active immunization for the prevention of invasive disease, pneumonia and acute otitis media caused by Streptococcus pneumoniae (S. pneumoniae) in infants, children and adolescents from 6 weeks to less than 18 years of age. Merck received approval from China’s National Medical Products Administration to expand the use of GARDASIL 9 [Human Papillomavirus (HPV) 9-valent Vaccine, Recombinant] for use in girls and women ages 9 to 45. The vaccine was previously approved for use in women ages 16 to 26. Infectious diseases pipeline highlights Merck will initiate a new Phase 3 clinical program with islatravir for the treatment of people with HIV-1 infection. These new Phase 3 studies will evaluate a once-daily oral combination of doravirine 100 mg and islatravir (DOR/ISL) 0.25 mg. Merck and Gilead Sciences will resume the Phase 2 clinical trial evaluating an investigational oral once-weekly combination treatment regimen of islatravir and Gilead’s lenacapavir in adults with HIV-1 infection who are virologically suppressed.

(Moderna) announced that Merck has exercised its option to jointly develop and commercialize personalized cancer vaccine mRNA-4157/V940 pursuant to the terms of its existing collaboration and license agreement. mRNA-4157/V940 is currently being evaluated in combination with KEYTRUDA as adjuvant treatment for patients with high-risk melanoma in a Phase 2 clinical trial being conducted by Moderna. Merck and Orna Therapeutics (Orna) announced a collaboration agreement to discover, develop and commercialize multiple programs, including vaccines and therapeutics in the areas of infectious diseases and oncology. This collaboration will combine Merck’s expertise in nucleic acid biology, clinical development, and manufacturing with Orna’s circular RNA technology. Merck and Orion Corporation (Orion) formed a global development and commercialization agreement for Orion’s investigational candidate ODM-208/MK-5684 and other drugs targeting cytochrome P450 11A1 (CYP11A1), an enzyme important in steroid production. ODM-208/MK-5684 is an oral, non-steroidal inhibitor of CYP11A1 currently being evaluated in a Phase 2 clinical trial for the treatment of patients with mCRPC. Merck acquired Vence, an innovator in virtual fencing for rotational grazing and livestock management, which complements Merck Animal Health’s broad portfolio of veterinary pharmaceuticals, vaccines and animal intelligence solutions. Environmental, Social and Governance (ESG) highlights Merck issued its 2021/2022 ESG Progress Report, highlighting the company’s performance and progress in ESG efforts across four main focus areas: Access to Health, Employees, Environmental Sustainability and Ethics & Values. These efforts come as part of a long-standing commitment to operating responsibly and creating value for patients and shareholders. Merck launched the Alliance for Equity in Cancer Care, an initiative to advance equity in cancer care in the U.S. by helping patients living in underserved communities receive timely access to high-quality, culturally responsive care. Merck was recognized on Fortune’s 2022 Change the World list for its work to make HPV vaccines broadly available in underserved countries through partnerships and manufacturing investments. Third-quarter revenue performance The following table reflects sales of the company’s top pharmaceutical products, as well as sales of Animal Health products.

Pharmaceutical sales growth in the third quarter was 9% excluding LAGEVRIO sales and 15% excluding LAGEVRIO sales and the impact of foreign exchange, primarily driven by oncology, vaccines and hospital acute care products. The COVID-19 pandemic unfavorably affected sales in the third quarter of 2021 by approximately $350 million, which favorably impacted the growth rate in the third quarter of 2022. Growth in oncology was largely driven by higher sales of KEYTRUDA, which rose 20% to $5.4 billion in the quarter. Global sales growth of KEYTRUDA reflects continued strong momentum from metastatic indications including certain types of NSCLC, renal cell carcinoma, head and neck squamous cell carcinoma, triple-negative breast cancer (TNBC) and MSI-H cancers, and increased uptake across recent earlier-stage launches including certain types of neoadjuvant/adjuvant TNBC in the U.S. Growth in vaccines was primarily driven by higher combined sales of GARDASIL (Human Papillomavirus Quadrivalent [Types 6, 11, 16 and 18] Vaccine, Recombinant) and GARDASIL 9 vaccines to prevent certain cancers and other diseases caused by HPV. Third-quarter GARDASIL/GARDASIL 9 sales grew 15% to $2.3 billion, primarily driven by strong demand outside of the U.S., particularly in China, which also benefited from increased supply. Additionally, higher sales in the U.S. reflect public sector buying patterns. Growth in vaccines was partially offset by lower sales of PNEUMOVAX 23 (pneumococcal vaccine polyvalent), a vaccine to help prevent pneumococcal disease, which declined 53% to $131 million primarily reflecting lower U.S. demand as the market continues to shift toward newer adult pneumococcal conjugate vaccines. Growth in hospital acute care reflects higher demand globally for BRIDION (sugammadex) injection 100 mg/mL, a medicine for the reversal of neuromuscular blockade induced by rocuronium bromide or vecuronium bromide in adults and pediatric patients ages 2 years and older undergoing surgery. Sales increased 15% to $423 million, primarily due to an increase in its share among neuromuscular blockade reversal agents and an increase in surgical procedures. Growth in hospital acute care also reflects higher sales of ZERBAXA (ceftolozane and tazobactam), a combination cephalosporin antibacterial and beta-lactamase inhibitor for the treatment of adults with certain bacterial infections. Sales of $43 million resulted from the phased resupply initiated in the fourth quarter of 2021, which has been completed in 2022. Pharmaceutical sales growth was partially offset by lower combined sales of JANUVIA (sitagliptin) and JANUMET (sitagliptin and metformin HCI), which declined 15% to $1.1 billion, primarily reflecting lower demand and pricing in certain international markets as a result of generic competition, particularly in Europe, and lower demand in the U.S. The company lost market exclusivity for JANUVIA and JANUMET in China in July and in the EU in September, although JANUMET currently continues to have exclusivity in certain European markets. Animal Health revenue Animal Health sales totaled $1.4 billion for the third quarter of 2022, a decline of 3% compared with the third quarter of 2021. Excluding the unfavorable effect from foreign exchange, Animal Health sales grew 4% primarily reflecting higher pricing. Sales of livestock products also reflect higher demand for poultry products. Sales of companion animal products also reflect higher demand for the BRAVECTO (fluralaner) parasiticide line of products, partially offset by supply constraints for certain vaccines. Third-quarter expense information The tables below present selected expense information. $ in millions Third Quarter 2022 GAAP Acquisition- and Divestiture- Related Costs3 Restructuring Costs (Income) Loss from Investments in Equity Securities Non- GAAP2 Cost of sales $3,934 $446 $54 $- $3,434 Selling, general and administrative 2,520 22 26 - 2,472 Research and development 4,399 902 1 - 3,496 Restructuring costs 94 - 94 - - Other (income) expense, net 429 (26) - 350 105 Third Quarter 2021 Cost of sales $3,450 $346 $48 $- $3,056 Selling, general and administrative 2,336 61 5 - 2,270 Research and development 2,445 48 8 - 2,389 Restructuring costs 107 - 107 - - Other (income) expense, net (450) (10) - (684) 244 GAAP expense, EPS and related information Gross margin was 73.7% for the third quarter of 2022 compared to 73.8% for the third quarter of 2021. The decrease primarily reflects the impacts of higher revenue from third-party manufacturing arrangements and sales of LAGEVRIO, both of which have lower gross margins, as well as higher acquisition- and divestiture-related costs. The gross margin decline was largely offset by the favorable effects of product mix and foreign exchange. Selling, general and administrative (SG&A) expenses were $2.5 billion in the third quarter of 2022, an increase of 8% compared to the third quarter of 2021. The increase primarily reflects higher administrative costs, including compensation and benefit costs, as well as higher promotional spending, partially offset by the favorable impact of foreign exchange. Research and development (R&D) expenses were $4.4 billion in the third quarter of 2022 compared to $2.4 billion in the third quarter of 2021. The increase primarily reflects $887 million of intangible asset impairment charges related to the ArQule, Inc. acquisition, charges related to collaboration and licensing agreements with Moderna, Orna and Orion and higher clinical development spending. Other (income) expense, net, was $429 million of expense in the third quarter of 2022 compared to $450 million of income in the third quarter of 2021, primarily due to net unrealized losses from investments in equity securities in the third quarter of 2022, compared to net unrealized income from investments in equity securities in the third quarter of 2021. Other (income) expense, net, in the third quarter of 2022 also reflects lower pension costs compared to the third quarter of 2021. The effective income tax rate was 9.2% for the third quarter of 2022 compared to 13.2% in the third quarter of 2021. GAAP EPS was $1.28 for the third quarter of 2022 compared to $1.80 for the third quarter of 2021. Non-GAAP expense, EPS and related information Non-GAAP gross margin was 77.0% for the third quarter of 2022 compared to 76.8% for the third quarter of 2021. The increase in non-GAAP gross margin primarily reflects the favorable effects of product mix and foreign exchange, largely offset by the impacts of higher revenue from third-party manufacturing arrangements and sales of LAGEVRIO, both of which have lower gross margins. Non-GAAP SG&A expenses were $2.5 billion in the third quarter of 2022, an increase of 9% compared to the third quarter of 2021. The increase primarily reflects higher administrative costs, including compensation and benefit costs, as well as higher promotional spending, partially offset by the favorable impact of foreign exchange. Non-GAAP R&D expenses were $3.5 billion in the third quarter of 2022 compared to $2.4 billion in the third quarter of 2021. The increase primarily reflects charges related to collaboration and licensing agreements with Moderna, Orna and Orion and higher clinical development spending. Non-GAAP other (income) expense, net, was $105 million of expense in the third quarter of 2022 compared to $244 million of expense in the third quarter of 2021, reflecting lower pension costs. The non-GAAP effective income tax rate was 13.6% for the third quarter of 2022 compared to 12.8% in the third quarter of 2021. Non-GAAP EPS was $1.85 for the third quarter of 2022 compared to $1.78 for the third quarter of 2021. A reconciliation of GAAP to non-GAAP net income and EPS is provided in the table that follows. Third Quarter $ in millions, except EPS amounts 2022 2021 EPS GAAP EPS $1.28 $1.80 Difference 0.57 (0.02) Non-GAAP EPS that excludes items listed below2 $1.85 $1.78 Net Income GAAP net income1 $3,248 $4,567 Difference 1,455 (42) Non-GAAP net income that excludes items listed below1,2 $4,703 $4,525 Decrease (Increase) in Net Income Due to Excluded Items: Acquisition- and divestiture-related costs3 $1,344 $445 Restructuring costs 175 168 Loss (income) from investments in equity securities 350 (684) Net decrease (increase) in income before taxes 1,869 (71) Estimated income tax (benefit) expense (414) 29 Decrease (increase) in net income $1,455 $(42) Financial outlook Beginning in 2022, Merck no longer excludes expenses for upfront and milestone payments related to collaboration and licensing agreements, or charges related to pre-approval assets obtained in transactions accounted for as asset acquisitions from its non-GAAP results. Historically, the company excluded these charges to the extent they were considered by the company to be significant to the results of a particular period. These changes were made to align with views expressed by the U.S. Securities and Exchange Commission. Prior periods have been recast to reflect this change. For 2021, non-GAAP results have been recast to include $1.7 billion of incremental R&D expense, resulting in revised full-year 2021 EPS of $5.37. Full-year 2022 GAAP and non-GAAP results include $690 million of incremental R&D expense, recorded in the third quarter of 2022, for collaboration and licensing agreements with Moderna, Orna and Orion which negatively impacts expected full-year EPS by $0.22. As an on-going practice, the financial outlook will not include significant potential business development transactions. Merck continues to experience strong global momentum across its key pillars of growth, particularly in oncology and vaccines. As a result, Merck is raising and narrowing its full-year outlook for sales and non-GAAP EPS, despite a negative impact from foreign exchange. At mid-October 2022 exchange rates, Merck expects sales growth of 20% to 21% in 2022, with full-year sales estimated to be between $58.5 billion and $59.0 billion, including a negative impact from foreign exchange of approximately 4%, including a less than 1% incremental negative impact from prior sales outlook. Excluding LAGEVRIO, Merck expects sales growth of approximately 12% for full-year 2022. Merck expects its full-year non-GAAP effective income tax rate to be approximately 14%. Merck is lowering its expected full-year 2022 GAAP EPS to be between $5.68 and $5.73. Merck is raising and narrowing its expected full-year 2022 non-GAAP EPS to be between $7.32 and $7.37, including a negative impact from foreign exchange of approximately 4% at mid-October exchange rates. Operational strength of approximately $0.20 is partially offset by the following negative impacts, which were not reflected previously in the outlook: An option payment to Moderna of $250 million A less than 1% incremental impact from foreign exchange The non-GAAP range excludes acquisition- and divestiture-related costs and costs related to restructuring programs as well as income and losses from investments in equity securities. The company is narrowing its expected full year sales range of LAGEVRIO to be between $5.2 billion and $5.4 billion. Merck shares profits equally with its partner, Ridgeback, which is reflected in cost of sales. The following table summarizes the company’s full-year 2022 financial outlook. GAAP Non-GAAP2 Sales $58.5 to $59.0 billion $58.5 to $59.0. billion* Operating expenses $22.5 to $22.9 billion $21.3 to $21.7 billion Effective tax rate Approximately 11% Approximately 14% EPS** $5.68 to $5.73 $7.32 to $7.37 *The company does not have any non-GAAP adjustments to sales. **EPS outlook for 2022 assumes a share count (assuming dilution) of approximately 2.54 billion shares.
