A high-quality franchise with exceptional cash conversion and four straight earnings beats is offset by failed price momentum and near-zero upside to analyst targets, making this a hold candidate rather than a fresh entry point until the technical picture and risk/reward geometry improve.

About Merck & Company, Inc.
About Merck & Company, Inc.
Keytruda/Keytruda Qlex generated $31.7 billion in 2025 — 49% of Merck's total company sales of $65.0 billion — and received FDA approval in September 2025 for a subcutaneous formulation (Keytruda Qlex) across most adult solid tumor indications. Gardasil/Gardasil 9 contributed $5.2 billion (down from $8.6 billion in 2024 due to significantly lower demand in China), while Winrevair reached $1.4 billion in its first full year of commercialization. Merck's Pharmaceutical segment totaled $58.1 billion and Animal Health $6.4 billion.
Merck earns revenue through its Pharmaceutical segment — selling primarily through drug wholesalers, retailers, hospitals, and managed health care providers — and its Animal Health segment, which sells to veterinarians, animal producers, and pet owners. Alliance revenues from Lynparza (in collaboration with AstraZeneca) contributed $1.5 billion and Lenvima (with Eisai) added $1.1 billion in 2025. The pricing environment is under pressure on multiple fronts: HHS selected Januvia for IRA government price-setting effective January 1, 2026, and Janumet/Janumet XR face government pricing effective January 1, 2027. Merck expects HHS to select Keytruda for IRA price-setting in 2027, with a resulting lower price effective January 1, 2029, after which U.S. Keytruda sales are expected to decline materially.

The patent cliff converges on several top products simultaneously. Bridion ($1.8 billion in 2025) loses U.S. market exclusivity in July 2026; Januvia and Janumet lose U.S. exclusivity in May 2026, with Merck expecting to lose nearly all domestic sales subsequently. Most critically, the primary Keytruda compound patent expires in December 2028, when biosimilar competition could begin, with European compound patent expiry in 2031 and potential data exclusivity challenges in Europe arising as early as July 2026.
