Key Highlights

Three core themes emerged from the quarterly results and commentary. First, financial performance exceeded consensus estimates, with organic revenue growth (ex-foreign exchange) of 3% YoY, even as expected headwinds hit non-core segments: Gardasil sales fell 22% YoY due to lower demand in China and Japan and U.S. CDC purchase timing, in line with management forecasts, while pneumococcal vaccine CAPVAXIVE grew 31% YoY to offset part of the decline.

Expert Insights

From a fundamental perspective, Merck’s Q1 results address two key investor concerns that have weighed on the stock in recent quarters: overreliance on KEYTRUDA and the pace of portfolio diversification. With 20+ recently launched assets, nearly all with management-identified blockbuster potential, now contributing a growing share of top-line growth, the company is successfully de-risking its exposure to KEYTRUDA’s upcoming patent expiry, even as the flagship therapy continues to deliver consistent mid-single-digit growth via expanded indications. The one-time acquisition charges for Sedera and Terns are non-recurring, and underlying operational efficiency remains strong: adjusted operating expense growth of 2% YoY is well below revenue growth, highlighting the success of Merck’s multi-year cost optimization program. From a pipeline perspective, the upcoming approval of enlicitide is a material long-term catalyst, as the oral PCSK9 inhibitor targets a $12 billion+ addressable market for lipid disorder treatment, filling a key gap in Merck’s cardiometabolic portfolio. The Terns Pharmaceuticals acquisition, meanwhile, adds a potential best-in-class chronic myeloid leukemia asset with $2 billion+ peak sales potential, further diversifying Merck’s oncology pipeline beyond immuno-oncology. Merck’s new business unit operating structure and multi-year AI partnerships with Google Cloud, Tempus AI, and the Mayo Clinic are also underappreciated value drivers, as they are expected to cut clinical trial timelines by 15% to 20% and improve drug discovery success rates over the next 3 to 5 years. Risks to the outlook include a $250 million KEYTRUDA sales headwind in Q3 2026 tied to first-quarter purchase timing, potential labeling restrictions for enlicitide, and ongoing Gardasil demand weakness in APAC markets. However, management’s decision to raise full-year guidance despite these headwinds signals high confidence in underlying demand for its core portfolio. Merck’s current “Moderate Buy” consensus rating, with an average 12-month price target 12% above current trading levels, is justified, with upside risk if upcoming pipeline readouts and regulatory approvals exceed expectations.
