What MRK reported on Oct 29, 2026

The quarter

Sales of $18.1B.

“The increase was primarily due to a $400 million charge related to a global license agreement with SciBrunch and higher clinical development spending, partially offset by lower restructuring costs and a $200 million reduction in R&D expenses as part of a funding agreement with Blackstone Life Sciences (Blackstone).”

About Merck

Merck makes pharmaceutical products to treat several conditions in a number of therapeutic areas, including cardiometabolic disease, cancer, and infections. In cancer, the firm's immuno-oncology platform, led by Keytruda, is a major contributor to overall sales. The company also has a substantial vaccine business aimed at preventing pediatric diseases, as well as Gardasil for human papillomavirus. Additionally, Merck sells animal health-related drugs. From a geographical perspective, 53% of the company's 2025 sales were generated from US human health (pharmaceuticals and vaccines).
