Key insights and themes extracted from this filing
Worldwide sales decreased by 2% year-over-year for both Q2 and 6M 2025, reaching $15.8 billion and $31.3 billion respectively. This was primarily driven by a 15% decline in international sales for the six months ended June 30, 2025, largely due to a 68% drop in China sales, despite a robust 13% increase in U.S. sales.
Net income attributable to Merck & Co., Inc. plummeted 18.8% in Q2 2025 to $4.4 billion and 7.0% for 6M 2025 to $9.5 billion. This decline was largely driven by a 15.7% increase in R&D expenses to $4.0 billion in Q2 and a staggering 600% surge in restructuring costs to $560 million in Q2 2025, reflecting significant strategic investments and operational adjustments.
Net cash provided by operating activities decreased by 33.6% to $5.8 billion for the first six months of 2025, down from $8.7 billion in the prior year. This reduction was primarily due to $1.7 billion in upfront and milestone payments related to certain collaborations, licensing agreements, and acquisitions, indicating substantial investments in future growth drivers.
Merck entered a definitive agreement to acquire Verona Pharma for approximately $10 billion in July 2025, gaining Ohtuvayre (COPD treatment). Additionally, a $200 million upfront payment was made for an exclusive license agreement with Hengrui Pharma for MK-7262, an investigational Lipoprotein(a) inhibitor, signaling aggressive pipeline expansion.
Despite overall sales decline, Keytruda sales grew 9% in Q2 2025 to $7.96 billion, and Lynparza alliance revenue increased 17% to $370 million. The new cardiovascular drug Winrevair generated $336 million in Q2 2025, demonstrating successful organic growth and new product uptake in critical therapeutic areas.
Merck initiated a new 2025 Restructuring Program with estimated cumulative pretax costs of $3.0 billion, targeting $1.7 billion in annual cost savings by 2027. These savings are intended to be reinvested into strategic growth areas, indicating a proactive approach to optimizing operations for future expansion.
Management approved a new 2025 Restructuring Program, incurring $649 million in pretax costs in Q2 2025, with an estimated total cost of $3.0 billion. This program aims to generate approximately $1.7 billion in annual cost savings by 2027, primarily through employee separation and facility optimization, demonstrating a commitment to operational efficiency.
In response to the American Rescue Plan Act and IRA, Merck lowered the list price of Januvia products to align with net prices, aiming for higher U.S. net sales in 2025. The company also sued the U.S. government regarding the IRA's Drug Price Negotiation Program, indicating a strong defense of its pricing power.
Merck voluntarily withdrew the BLA for MK-1022 (patritumab deruxtecan) due to confirmatory trial results and manufacturing findings. Additionally, Phase 3 trials for Keytruda (KEYNOTE-937) and Keytruda+Lenvima (LEAP-014) did not meet primary endpoints, reflecting management's willingness to discontinue programs that do not meet efficacy targets.
Merck faces mounting product liability lawsuits for Gardasil/Gardasil 9 (approximately 125 cases) and Dr. Scholl's Foot Powder (approximately 575 cases). Additionally, new securities litigation alleges federal securities law violations regarding Gardasil/Gardasil 9 demand in China, and significant patent litigation continues for key products like Januvia and Keytruda, creating substantial legal uncertainty.
The U.S. Inflation Reduction Act (IRA) has selected Januvia for price negotiation (effective 2026), with Janumet and Janumet XR to follow (effective 2027), and Keytruda potentially eligible for 2027 selection. This, coupled with the elimination of the Medicaid rebate cap and the potential 'Most Favored Nation' drug pricing policy, creates significant headwinds for future U.S. sales and profitability.
Merck received Notices of Proposed Adjustment (NOPAs) from the IRS in April 2025, proposing a $1.3 billion increase in one-time transition tax and $260 million in penalties. While Merck intends to vigorously contest these, an unsuccessful defense could result in a material impact to its financial statements, representing a notable tax-related risk.
Keytruda sales increased 9% in Q2 2025 to $7.96 billion and 7% for 6M 2025 to $15.16 billion, driven by higher demand across multiple approved metastatic and earlier-stage indications in the U.S. and internationally. This sustained growth reinforces Merck's dominant position in the oncology market despite emerging biosimilar competition in Argentina.
The successful launches and continued uptake of Capvaxive (pneumococcal vaccine) and Winrevair (pulmonary arterial hypertension) generated $129 million and $336 million in Q2 2025, respectively. These new revenue streams help diversify Merck's portfolio and offset the impact of upcoming patent expiries for key products like Januvia/Janumet and Bridion.
Gardasil/Gardasil 9 sales plummeted 55% in Q2 2025 to $1.13 billion, primarily due to lower demand and a temporary shipment pause in China. Additionally, sales of Simponi and Remicade declined 100% as marketing rights reverted to Johnson & Johnson in October 2024, indicating significant erosion in these segments.
The 2025 Restructuring Program, approved in July 2025, is projected to incur $3.0 billion in pretax costs but aims to achieve approximately $1.7 billion in annual cost savings by the end of 2027. This initiative, alongside the ongoing 2024 program targeting $750 million in annual savings, demonstrates a concerted effort to optimize the global manufacturing network and reduce operational expenses.
Gross margin improved by 70 basis points to 77.5% in Q2 2025 and 50 basis points to 77.7% for 6M 2025, primarily due to a favorable product mix. This indicates an effective shift towards higher-margin products, partially offsetting the impact of increased restructuring costs and inventory write-offs.
Manufacturing delays affected sales of ProQuad and Varivax, with the company anticipating supply constraints in international markets during 2025. Additionally, a temporary pause on Gardasil/Gardasil 9 shipments to China was implemented due to elevated inventory levels, highlighting ongoing operational bottlenecks.
R&D expenses increased by 16% in Q2 2025 to $4.0 billion, driven by a $200 million upfront payment for the MK-7262 license agreement with Hengrui Pharma and increased clinical development spending. This substantial investment underscores Merck's commitment to advancing its pipeline across multiple therapeutic areas.
Merck's acquisition of Verona Pharma for Ohtuvayre (PDE3/PDE4 inhibitor) and its exclusive license for MK-7262 (Lipoprotein(a) inhibitor) highlight a strategic focus on first-in-class and novel mechanism assets. The ongoing development of subcutaneous Keytruda (MK-3475A) further demonstrates innovation in drug delivery.
While MK-0616 (PCSK9 inhibitor) showed positive Phase 3 results, the BLA for MK-1022 was voluntarily withdrawn, and Keytruda (KEYNOTE-937) and Keytruda+Lenvima (LEAP-014) Phase 3 trials did not meet primary endpoints. This indicates a dynamic R&D landscape with both successes and setbacks requiring agile portfolio management.
Merck significantly increased share repurchases, spending $2.5 billion in the first six months of 2025, a 572.6% increase year-over-year. This follows a new $10 billion share repurchase authorization in January 2025, indicating management's belief in the company's intrinsic value and commitment to returning capital to shareholders.
The company committed approximately $10 billion to acquire Verona Pharma and spent $437 million on the WuXi Vaccines facility, alongside a $200 million upfront R&D payment for a new license agreement. Capital expenditures also rose 26.6% to $2.09 billion in 6M 2025, demonstrating a clear focus on long-term pipeline and manufacturing capabilities.
Net cash provided by operating activities decreased by 33.6% to $5.8 billion in 6M 2025, primarily due to substantial upfront payments for collaborations and acquisitions. While still positive, this reduction in operating cash flow necessitates increased reliance on financing activities, as evidenced by higher debt payments and share repurchases.
The 2025 Restructuring Program includes plans to 'reduce its global real estate footprint and continue to optimize its manufacturing network.' While not explicitly an ESG initiative, these actions could lead to reduced energy consumption and waste, contributing positively to environmental sustainability.
Merck continues to face significant product liability lawsuits related to Gardasil/Gardasil 9 (approximately 125 cases) and Dr. Scholl's Foot Powder (approximately 575 cases). These legal challenges underscore the ongoing need for robust product safety and patient trust, which are key aspects of social responsibility.
A putative class action and a stockholder derivative lawsuit were filed in 2025 alleging federal securities law violations and breach of fiduciary duty related to Gardasil/Gardasil 9 demand in China. These legal actions place Merck's corporate governance practices under scrutiny, emphasizing the importance of transparent reporting and oversight.
Worldwide sales declined 2% in Q2 and 6M 2025, significantly impacted by lower demand in China (due to inventory and shipment pause) and generic competition in international markets for products like Bridion. The U.S. Inflation Reduction Act (IRA) and potential 'Most Favored Nation' drug pricing policies further exacerbate pricing challenges, notably for Januvia.
While foreign exchange rate changes had a negative impact on international sales (e.g., 15% decline in 6M 2025 international sales), they contributed favorably to 'Other (income) expense, net,' which shifted from a $42 million expense in Q2 2024 to a $7 million income in Q2 2025. This highlights the dual effect of currency volatility on Merck's financial results.
Sales of Lagevrio, Merck's COVID-19 antiviral, decreased significantly by 60% for the first six months of 2025, primarily due to declining COVID-19 cases in markets like Japan. This illustrates how changes in the global health environment directly influence demand for specific therapeutic products.
