Merck saw revenue dip slightly to $15.5B in Q1 2025, with earnings per share increasing on both a GAAP and non-GAAP basis. Strength in oncology, particularly KEYTRUDA, and growth in animal health helped offset vaccine declines, especially GARDASIL sales in China.
Total revenue decreased by 2% to $15.5B, but grew 1% excluding foreign exchange.
KEYTRUDA sales reached $7.205B, up 4% from the prior year.
GARDASIL/GARDASIL 9 sales dropped sharply by 41% to $1.327B due to weak China demand.
Animal Health segment revenue rose 5% to $1.588B, led by livestock products and recent acquisitions.
Merck maintained its full-year sales outlook and slightly reduced non-GAAP EPS guidance due to anticipated one-time licensing costs.
