Merck's Q3 2025 Profit Rises Amid Keytruda Strength and Sales Fluctuations
Merck's stock declined after its key products, Keytruda and Winrevair, fell short of sales estimates, despite overall revenue beating expectations. The company is preparing for biosimilar competition for Keytruda starting in 2028 and has made significant acquisitions to offset potential revenue declines. Merck has also updated its full-year outlook, expecting slight increases in sales and earnings for 2025.
