Key idiosyncratic risks

On competition:

As previously disclosed, while two patents in the Keytruda composition of matter patent family expire in May and November of 2029, respectively, the Company expects these patents to be the subject of litigation and, thus, biosimilar competition could begin in December 2028 when the primary compound patent expires.

Source: risk; filed 2026-02-24; SEC filing; fact QUOTE_MRK_RISK_7.

On intense product competition:

Also, the Company’s products face intense competition from competitors’ products.

Source: risk; filed 2026-02-24; SEC filing; fact QUOTE_MRK_RISK_25.

On supply-chain exposure:

These risks could disrupt the Company’s operations and its supply chain, which may result in increased costs.

Source: risk; filed 2026-02-24; SEC filing; fact QUOTE_MRK_RISK_29.

Recent developments

On healthcare revenue movement:

The international sales decline was primarily due to lower sales of Gardasil/Gardasil 9, Simponi, Lagevrio, Januvia, Bridion, Remicade, and Janumet, partially offset by higher sales of Keytruda, Prevymis, Winrevair, increased alliance revenue from Koselugo and Lynparza, as well as higher sales of animal health products.
