10-QPeriod: Q1 FY2026

Merck & Co., Inc. Quarterly Report for Q1 Ended Mar 31, 2026

Filed May 4, 2026For Securities:MRK

Summary

Merck & Co., Inc. reported a net loss of $4.24 billion ($1.72 per share) for the first quarter of 2026, a significant reversal from the $5.08 billion net income ($2.01 per share) reported in the same period of 2025. This loss was largely driven by a substantial increase in Research and Development (R&D) expenses, primarily due to the $9.2 billion acquisition of Cidara Therapeutics and an anticipated $5.8 billion charge from the pending acquisition of Terns Pharmaceuticals. Despite the reported net loss, the company's sales showed resilience, growing 5% to $16.3 billion year-over-year, supported by strong performance in oncology, particularly Keytruda, and the Animal Health segment. However, the significant R&D investments, coupled with ongoing restructuring costs and pressures on drug pricing due to regulatory changes like the Inflation Reduction Act, present a challenging near-term outlook. Investors should closely monitor the integration of recent acquisitions and the impact of evolving healthcare policies on future profitability.
