Keytruda, Merck’s flagship immuno-oncology drug, represented approximately 46% of total 2024 revenue, contributing around $29.5 billion, underscoring its critical role in the company’s revenue profile. With patent expiration looming at the end of 2028, Merck anticipates biosimilar competition that could reduce Keytruda sales by 10-20%, potentially dropping peak sales from $36 billion to below $20 billion within five years, compounded by pricing pressures under the U.S. Inflation Reduction Act (IRA) (GlobeNewswire.
Simultaneously, Gardasil’s sales in China have plunged sharply, with a 41% year-over-year decline in H1 2025 and a 55% drop in Q2 alone, driven by economic uncertainty and anti-corruption measures impacting healthcare provider incentives. Merck’s decision to pause shipments to China since January 2025 to manage inventory further exacerbates this revenue contraction (Investing.com.

Competitive Landscape and Sector Trends#
Merck operates in a highly competitive pharmaceutical environment, where innovation and pipeline robustness are key differentiators. The patent cliff for blockbuster drugs like Keytruda is a common industry challenge, with competitors such as Bristol-Myers Squibb and Pfizer also facing biosimilar pressures. Merck’s strategic emphasis on biologics, immunology, and diversified therapeutic areas aligns with broader sector trends favoring specialty medicines and personalized therapies.
The company’s restructuring and pipeline investments reflect an industry-wide shift toward cost efficiency and innovation-driven growth, mirroring similar moves by peers that have historically resulted in improved margins and shareholder value when successfully executed.
