**<u>Item 2.02. Results of Operations and Financial Condition</u>.**

The following information, including the exhibits hereto, is being furnished pursuant to this Item 2.02.

Incorporated by reference is a press release issued by Merck & Co., Inc. on July 29, 2025, regarding earnings for the second quarter of 2025, attached as Exhibit 99.1. Also incorporated by reference is certain supplemental information not included in the press release, attached as Exhibit 99.2.

This information shall not be deemed to be "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), or otherwise subject to the liabilities of that Section, and is not incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such filing.

**<u>Item 2.05. Costs Associated with Exit or Disposal Activities.</u>**

On July 25, 2025, the Company approved a new restructuring program (2025 Restructuring Program) designed to position the Company for its next chapter of growth and to successfully advance its pipeline and launch new products across multiple therapeutic areas. As part of this program, the Company expects to eliminate certain positions in sales and administrative organizations, as well as research and development. The Company will, however, continue to hire employees into new roles across all strategic growth areas of the business. In addition, the Company will reduce its global real estate footprint and continue to optimize its manufacturing network, aligning the geography of its global manufacturing footprint to its customers and reflecting changes in the Company's business.

Most actions contemplated under the 2025 Restructuring Program are expected to be largely completed by the end of 2027, with the exception of certain manufacturing actions, which are expected to be substantially completed by the end of 2029. The cumulative pretax costs to be incurred by the Company to implement the program are estimated to be approximately $3.0 billion, of which approximately 60% will be cash, relating primarily to employee separation expense and contractual termination costs. The remainder of the costs will be non-cash, relating primarily to the accelerated depreciation of facilities. The Company expects the actions under the 2025 Restructuring Program to result in annual cost savings of approximately $1.7 billion, which will be substantially realized by the end of 2027. The 2025 Restructuring Program is part of the Company's multiyear optimization initiative anticipated to achieve $3.0 billion in annual cost savings by the end of 2027, which will be fully reinvested into strategic growth areas of the business.

\*Refer to table on page 7.

For the second quarter of 2025, Generally Accepted Accounting Principles (GAAP) earnings per share (EPS) assuming dilution was $1.76 and non-GAAP EPS was $2.13. GAAP and non-GAAP EPS in the second quarter of 2025 include a charge of $0.07 per share for an upfront payment to Jiangsu Hengrui Pharmaceuticals Co., Ltd. (Hengrui Pharma) upon closing of a license agreement. Non-GAAP EPS excludes acquisition- and divestiture-related costs, costs related to restructuring programs, and income and losses from investments in equity securities. Non-GAAP EPS in the second quarter of 2025 also excludes tax benefits primarily resulting from favorable audit adjustments. Non-GAAP EPS in the second quarter of 2024 also excludes a tax benefit due to a reduction in reserves for unrecognized income tax benefits, resulting from the expiration of the statute of limitations for assessments related to the 2019 federal tax return year.

Year-to-date results can be found in the attached tables.

<sup>2</sup> Net income attributable to the Company.

<sup>3</sup> The Company is providing certain 2025 and 2024 non-GAAP information that excludes certain items because of the nature of these items and the impact they have on the analysis of underlying business performance and trends. 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.

**<u>Second-Quarter Sales Performance</u>**

| Total Sales | $15806 | $16112 | -2% | -2% |  |
| Pharmaceutical | 14050 | 14408 | -2% | -3% | Decline primarily due to vaccines and immunology, partially offset by growth in oncology and cardiology. |
| KEYTRUDA | 7956 | 7270 | 9% | 9% | Growth driven by continued strong global demand from metastatic indications, including bladder, endometrial and gastric cancers, and increased global uptake in earlier-stage indications, including triple-negative breast cancer, renal cell carcinoma (RCC) and cervical cancer, as well as non-small cell lung cancer in the U.S. |
| GARDASIL/GARDASIL 9 | 1126 | 2478 | -55% | -55% | Decline primarily due to lower demand in China. Excluding China, sales declined 3%, or 4% excluding impact of foreign exchange, reflecting lower demand in Japan following a national catch-up immunization program, as well as timing of public-sector purchases in certain international markets. U.S. sales increased 2% in the quarter. |
| JANUVIA/JANUMET | 623 | 629 | -1% |  | Decrease primarily attributable to lower demand in China, impacts of generic competition in most international markets, and lower demand in the U.S. due to competitive pressure, which were largely offset by higher net pricing in the U.S. |
| PROQUAD, M-M-R II and VARIVAX | 609 | 617 | -1% | -2% | Decrease primarily reflects lower U.S. sales due to unfavorable VARIVAX public-sector activity and M-M-R II private-sector buy-out, partially offset by partial replenishment of PROQUAD doses borrowed from the U.S. Centers for Disease Control and Prevention (CDC) Pediatric Vaccine Stockpile, and higher pricing. |
| BRIDION | 461 | 455 | 1% | 1% | Increase primarily due to higher demand in the U.S., partially offset by lower demand in most international markets due to ongoing generic competition. |
| Lynparza\* | 370 | 317 | 17% | 15% | Growth primarily due to higher demand in the U.S. and certain international markets. |

**<u>GAAP Expense, EPS and Related Information</u>**

Gross margin was 77.5% for the second quarter of 2025 compared with 76.8% for the second quarter of 2024. The increase was primarily due to the favorable impact of product mix, partially offset by higher restructuring costs and inventory write-offs.

Selling, general and administrative (SG&A) expenses were $2.6 billion in the second quarter of 2025, a decrease of 3% compared with the second quarter of 2024. The decrease was primarily due to lower administrative, restructuring and promotional costs.

Research and development (R&D) expenses were $4.0 billion in the second quarter of 2025, an increase of 16% compared with the second quarter of 2024. The increase was primarily due to a $200 million charge for an upfront payment made in the second quarter of 2025 for a license agreement with Hengrui Pharma, increased clinical development spending, higher compensation and benefit costs, and higher restructuring costs.

Other (income) expense, net, was $7 million of income in the second quarter of 2025 compared with $42 million of expense in the second quarter of 2024.

The effective tax rate of 11.4% for the second quarter of 2025 includes a 2.9 percentage point favorable impact due to tax benefits primarily resulting from favorable audit adjustments.

<sup>4</sup> 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.

GAAP EPS was $1.76 for the second quarter of 2025 compared with $2.14 for the second quarter of 2024. The decrease reflects increased operating expenses driven by higher restructuring costs and research and development spending, a charge related to the closing of a license agreement with Hengrui Pharma, unfavorable tax impacts, and the unfavorable impact of foreign exchange.

**<u>Non-GAAP Expense, EPS and Related Information</u>**

Non-GAAP gross margin was 82.2% for the second quarter of 2025 compared with 80.9% for the second quarter of 2024. The increase was primarily due to the favorable impact of product mix, partially offset by higher inventory write-offs.

Non-GAAP SG&A expenses were $2.6 billion in the second quarter of 2025, a decrease of 2% compared with the second quarter of 2024. The decrease was primarily due to lower administrative and promotional costs.

Non-GAAP R&D expenses were $4.0 billion in the second quarter of 2025, an increase of 15% compared with the second quarter of 2024. The increase was primarily due to a $200 million charge for an upfront payment made in the second quarter of 2025 for a license agreement with Hengrui Pharma, increased clinical development spending, and higher compensation and benefit costs.

Non-GAAP other (income) expense, net, was $54 million of expense in the second quarter of 2025 compared with $108 million of expense in the second quarter of 2024.

The non-GAAP effective tax rate was 15.0% for the second quarter of 2025.

Non-GAAP EPS was $2.13 for the second quarter of 2025 compared with $2.28 for the second quarter of 2024. The decrease reflects increased operating expenses driven by higher research and development spending, a charge related to the closing of a license agreement with Hengrui Pharma, and the unfavorable impact of foreign exchange.

**<u>Planned Acquisition of Verona Pharma</u>**

On July 9, 2025, the Company furthered its science-led business development strategy by announcing an agreement under which the Company, through a subsidiary, will acquire Verona Pharma plc (Verona Pharma) for $107 per American Depository Share, each of which represents eight Verona Pharma ordinary shares, for a total transaction value of approximately $10 billion. Through the acquisition, the Company will add Ohtuvayre, a first-in-class selective dual inhibitor of phosphodiesterase 3 and 4 (PDE3 and PDE4), to its growing cardio-pulmonary pipeline and portfolio.

The U.S. Food and Drug Administration (FDA) approved Ohtuvayre in June 2024 for the maintenance treatment of chronic obstructive pulmonary disease (COPD) in adult patients. It is the first novel inhaled mechanism for the treatment of COPD in more than 20 years. The transaction is anticipated to close in the fourth quarter of 2025.

**<u>Pipeline and Portfolio Highlights</u>**

In the second quarter, the Company continued to advance its broad and diverse pipeline with multiple regulatory and clinical milestones.

In oncology, the FDA approved KEYTRUDA as part of a therapy regimen for the treatment of certain adult patients with resectable locally advanced head and neck squamous cell carcinoma (HNSCC), based on results from the Phase 3 KEYNOTE-689 trial. This approval is the first perioperative anti-PD-1 treatment regimen for adults with resectable locally advanced HNSCC whose tumors express PD-L1 (CPS ≥1). In addition, the Ministry of Health, Labor and Welfare (MHLW) in Japan approved WELIREG as monotherapy for the treatment of adults with von Hippel-Lindau (VHL) disease-associated tumors, and for adults with unresectable or metastatic RCC that has progressed after chemotherapy.

<sup>5</sup> Includes the estimated tax impacts on the reconciling items based on applying the statutory rate of the originating territory of the non-GAAP adjustments for both periods presented. Amount in the second quarter of 2025 also includes a $146 million benefit primarily resulting from favorable audit adjustments. Amount in the second quarter of 2024 also includes a $259 million benefit due to a reduction in reserves for unrecognized income tax benefits resulting from the expiration of the statute of limitations for assessments related to the 2019 federal tax return year.

At the 2025 American Society of Clinical Oncology Annual Meeting, the Company announced new research across more than 25 types of cancer in multiple treatment settings. Data were presented for several candidates, including MK-1084, an investigational oral selective *KRAS* G12C inhibitor, and from the Company's pipeline of antibody-drug conjugates (ADCs). The Company also presented data from Phase 3 trials evaluating new combination regimens with KEYTRUDA, and longer-term data for studies of KEYTRUDA and WELIREG, with the KEYTRUDA studies including people with earlier stages of cancer.

The Company announced results from the Phase 3 KEYNOTE-B96 trial (also known as ENGOT-ov65) evaluating KEYTRUDA plus chemotherapy, which met its primary endpoint of progression-free survival (PFS) for the treatment of patients with platinum-resistant recurrent ovarian cancer whose tumors express PD-L1 and in all comers, as well as a secondary endpoint of overall survival (OS) in patients whose tumors express PD-L1. In addition, a pre-specified interim analysis of the Phase 3 KEYNOTE-937 study found that compared to placebo, KEYTRUDA did not show a statistically significant improvement in the primary endpoint of recurrence-free survival for certain patients with hepatocellular carcinoma. Also, a pre-specified interim analysis of the Phase 3 LEAP-014 trial found that KEYTRUDA plus Lenvima, in combination with platinum-based chemotherapy, did not show a statistically significant improvement in its primary endpoint of OS compared to KEYTRUDA plus chemotherapy for the first-line treatment of patients with metastatic esophageal squamous cell carcinoma (ESCC).

In vaccines and infectious diseases, the Company received FDA approval of ENFLONSIA for the prevention of respiratory syncytial virus (RSV) lower respiratory tract disease in newborns and infants who are born during or entering their first RSV season. ENFLONSIA is the first and only RSV preventive option administered to infants using the same dose regardless of weight. The CDC's Advisory Committee on Immunization Practices (ACIP) also recommended ENFLONSIA for the prevention of RSV in infants younger than 8 months of age born during or entering their first RSV season. In addition, the Company announced initiation of the MOBILIZE-1 Phase 3 trial evaluating V181, an investigational single-dose quadrivalent vaccine for the prevention of dengue disease.

In addition, the FDA accepted a New Drug Application (NDA) for doravirine/islatravir, an investigational, once-daily, oral, two-drug regimen for the treatment of adults with virologically suppressed HIV-1 based on the Phase 3 MK-8591A-051 and MK-8591A-052 trials. The FDA set a Prescription Drug User Fee Act (PDUFA) date of April 28, 2026. The Company also announced the initiation of the EXPrESSIVE Phase 3 trials for MK-8527, its investigational once-monthly oral candidate for HIV pre-exposure prophylaxis (PrEP).

In cardiovascular disease, the Company announced positive topline results from Phase 3 CORALreef HeFH and CORALreef AddOn, the first two of three Phase 3 clinical trials evaluating the safety and efficacy of enlicitide decanoate, an investigational, oral proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor being evaluated for the treatment of adults with hyperlipidemia already on lipid-lowering therapies, including at least a statin. In both trials, enlicitide demonstrated statistically significant and clinically meaningful reductions in low-density lipoprotein cholesterol. If approved, it would be the first marketed oral PCSK9 inhibitor.

In addition, the FDA granted priority review for a new supplemental Biologics License Application for WINREVAIR seeking approval to update the U.S. product label based on compelling results from the Phase 3 ZENITH trial. The FDA has set a PDUFA date of Oct. 25, 2025. The Company also provided an update on the Phase 3 HYPERION study evaluating WINREVAIR in recently diagnosed adults with pulmonary arterial hypertension (PAH). In the study, WINREVAIR added on top of background therapy within 12 months after initial diagnosis of PAH demonstrated a statistically significant and clinically meaningful reduction in the risk of clinical worsening events when compared to placebo. Further, the MHLW in Japan approved sotatercept for the treatment of adults with PAH under the trademark AIRWIN. It is the first activin signaling inhibitor therapy for PAH approved in Japan.

In the Animal Health business, the FDA approved BRAVECTO QUANTUM, an injectable formulation of BRAVECTO for dogs for the treatment and persistent killing of fleas and ticks. In addition, the European Commission (EC) approved NUMELVI tablets for dogs, a once-daily, second-generation Janus kinase (JAK) inhibitor, indicated for the treatment of pruritus associated with allergic dermatitis including atopic dermatitis and treatment of clinical manifestations of atopic dermatitis.

\*References to the Company's name in the above news release titles have been modified for the purpose of this announcement.

**<u>New Multiyear Optimization Initiative, Which Includes a Restructuring Program</u>**

The Company launched a new multiyear optimization initiative to enable the transformation of its portfolio by generating an expected $3.0 billion in annual cost savings from productivity actions, which will be fully reinvested to support new product launches and its pipeline across multiple therapeutic areas.

In July 2025, as part of this initiative, the Company approved a new restructuring program, in which it expects to eliminate certain administrative, sales and R&D positions. The Company will, however, continue to hire employees into new roles across strategic growth areas of the business. In addition, the Company will reduce its global real estate footprint and continue to optimize its manufacturing network, aligning the geography of its global manufacturing to its customers and reflecting changes in the Company's business.

The Company anticipates cumulative pretax costs related to the program to be approximately $3.0 billion. For the second quarter of 2025, the Company recorded charges in its GAAP results of $649 million related to this restructuring program.

The Company expects the actions under the restructuring program to result in annual cost savings of approximately $1.7 billion, which will be substantially realized by the end of 2027. This restructuring program is part of the multiyear optimization initiative expected to achieve $3.0 billion in annual cost savings by the end of 2027.

**<u>Manufacturing and R&D Investment</u>**

The Company continued to make long-term investments in its U.S. manufacturing and R&D capabilities. This includes the start of construction for a $1.0 billion, 470,000-square-foot state-of-the-art biologics center of excellence in Wilmington, Delaware, which will serve as a launch and commercial production facility and the primary U.S. manufacturing site for KEYTRUDA. In addition, the Company announced an $895 million expansion of its Animal Health manufacturing facility in De Soto, Kansas; the 200,000-square-foot facility will increase capacity for Animal Health vaccines and biologic products.

**<u>Full-Year 2025 Financial Outlook</u>**

The following table summarizes the Company's full-year financial outlook.

---

| | | |
|:---|:---|:---|
|  | **Full Year 2025** | **Full Year 2025** |
|  | **Updated** | **Prior** |
| Sales<sup>\*</sup> | $64.3 billion to $65.3 billion | $64.1 billion to $65.6 billion |
| Non-GAAP Gross margin<sup>3</sup> | Approximately 82% | Approximately 82% |
| Non-GAAP Operating expenses<sup>3\*\*</sup> | $25.6 billion to $26.4 billion | $25.6 billion to $26.6 billion |
| Non-GAAP Other (income) expense, net<sup>3</sup> | $300 million to $400 million expense | $300 million to $400 million expense |
| Non-GAAP Effective tax rate<sup>3</sup> | 15.0% to 16.0% | 15.5% to 16.5% |
| Non-GAAP EPS<sup>3\*\*\*</sup> | $8.87 to $8.97 | $8.82 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.

\*\*Includes one-time R&D charges of $300 million for a milestone payment to LaNova Medicines Ltd. (LaNova) associated with the technology transfer for MK-2010 expected to be recorded in the third quarter of 2025 and $200 million for the upfront payment for the license agreement completed with Hengrui Pharma in the second quarter of 2025.

Outlook does not assume any additional significant potential business development transactions.

\*\*\*Includes one-time charges totaling $0.16 per share associated with the payment for the LaNova technology transfer for MK-2010 and upfront payment to Hengrui 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 $64.3 billion and $65.3 billion, including a revised negative impact of foreign exchange of approximately 0.5% at mid-July 2025 exchange rates.

The Company now expects its full-year non-GAAP effective income tax rate to be between 15.0% and 16.0%.

The Company now expects its full-year non-GAAP EPS to be between $8.87 and $8.97, including a revised negative impact of foreign exchange of approximately $0.15 per share. This revised non-GAAP EPS range continues to reflect the impacts of a one-time charge of $200 million (recorded in the second quarter of 2025) for an upfront payment made in connection with the closing of a license agreement with Hengrui Pharma and the one-time charge of $300 million (to be recorded in the third quarter of 2025) related to a payment to LaNova for the completion of the technology transfer for MK-2010, which will 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.

The financial outlook does not include the anticipated impact of the announced acquisition of Verona Pharma.

Consistent with past practice, the financial outlook does not assume additional significant potential business development transactions.

The $200 million of costs previously included in the Company's financial outlook related to the impact of tariffs is unchanged pending the outcome of additional potential government actions.

| Only the line items that are affected by non-GAAP adjustments are shown. |
| The Company is providing certain non-GAAP information that excludes certain items because of the nature of these items and the impact they have on the analysis of underlying business performance and trends. Management believes that providing non-GAAP information enhances investors' understanding of the Company's results because management uses non-GAAP measures 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. The non-GAAP information presented should be considered in addition to, but not as a substitute for or superior to, information prepared in accordance with GAAP. |
| <sup>(1)</sup> Amounts included in cost of sales reflect expenses for the amortization of intangible assets and intangible asset impairment charges, partially offset by a decrease in the estimated fair value measurement of liabilities for contingent consideration. Amounts included in selling, general and administrative expenses reflect integration, transaction and certain other costs related to acquisitions and divestitures. Amounts included in research and development expenses reflect the amortization of intangible assets. |
| <sup>(2)</sup> Amounts primarily include employee separation costs, accelerated depreciation and asset impairments associated with facilities to be closed or divested related to activities under the Company's formal restructuring programs. |
| <sup>(3)</sup> Represents the estimated tax impacts on the reconciling items based on applying the statutory rate of the originating territory of the non-GAAP adjustments. |

Only the line items that are affected by non-GAAP adjustments are shown.

The Company is providing certain non-GAAP information that excludes certain items because of the nature of these items and the impact they have on the analysis of underlying business performance and trends. Management believes that providing non-GAAP information enhances investors' understanding of the Company's results because management uses non-GAAP measures 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. The non-GAAP information presented should be considered in addition to, but not as a substitute for or superior to, information prepared in accordance with GAAP.

<sup>(1)</sup> Amounts included in cost of sales primarily reflect expenses for the amortization of intangible assets. Amounts included in selling, general and administrative expenses reflect integration, transaction and certain other costs related to acquisitions and divestitures. Amounts included in research and development expenses primarily reflect the amortization of intangible assets. Amounts included in other (income) expense, net, primarily reflect royalty income related to the prior termination of the Sanofi-Pasteur MSD joint venture.

<sup>(2)</sup> Amounts primarily include employee separation costs and accelerated depreciation associated with facilities to be closed or divested related to activities under the Company's formal restructuring programs.

<sup>(3)</sup> Represents the estimated tax impacts on the reconciling items based on applying the statutory rate of the originating territory of the non-GAAP adjustments.

<sup>(4)</sup> Represents a benefit due to a reduction in reserves for unrecognized income tax benefits resulting from the expiration of the statute of limitations for assessments related to the 2019 federal tax return year.
