Expert Insights

Senior sell-side analysts covering the large-cap pharma sector note that the divergent revisions to Merck’s Q1 estimates stem from two offsetting fundamental drivers playing out over the quarter. On the upside, IQVIA’s monthly U.S. prescription data shows Merck’s flagship oncology therapy Keytruda maintained a 48% market share in first-line non-small cell lung cancer (NSCLC) through Q1 2026, following a 3.2% list price increase implemented in January, which puts the franchise on track for a 4% YoY sales increase, 40 basis points above current consensus estimates. Downward revisions, by contrast, largely reflect foreign exchange headwinds: the U.S. dollar appreciated 7% against the euro and 6% against the Japanese yen over the quarter, which is expected to reduce reported international revenue by roughly 110 basis points, according to UBS’s pharma research team. Investors are widely expected to prioritize full-year guidance commentary over quarterly results, following Merck’s conservative 2026 outlook issued alongside Q4 2025 earnings. The current consensus full-year revenue estimate sits at $68.9 billion, 2.1% above the $67.5 billion midpoint of Merck’s prior guidance range. Any upward adjustment to the full-year revenue or EPS guidance ranges will likely trigger positive price action, while retention of the existing conservative guidance is likely to extend the stock’s recent underperformance relative to peers. Analysts at Morgan Stanley note that Merck’s current valuation discount largely reflects investor concerns around upcoming 2028 biosimilar competition for Keytruda, which generated 35% of the firm’s total revenue in 2025. For long-term investors, commentary around launch timelines for Merck’s next-generation oncology pipeline, including phase 2 candidate MK-7684A, will be a key catalyst for valuation re-rating, as successful commercialization of pipeline assets could offset up to 60% of expected Keytruda revenue losses by 2030, per Morgan Stanley’s base case model. Given the discounted valuation, even in-line Q1 results and stable full-year guidance could trigger a relief rally for MRK, as markets have already priced in a 3-5% downside miss to guidance, per Goldman Sachs derivatives research. Short-term traders should position for heightened post-earnings volatility, with option markets implying a 4.2% single-day price move following the release, above the 2.9% average post-earnings move for Merck over the past 8 quarters.
