The Q1 results delivered several material positives, alongside modest pipeline underperformance, for investors weighing Merck’s long-term growth thesis: 1. **Winrevair outperformance**: The pulmonary arterial hypertension therapy generated $525 million in Q1 sales, handily beating consensus estimates, with double-digit demand growth across the U.S., Japan, and core EU markets.

Expert Insights

Barclays senior biopharma analyst Emily Field called the Q1 print a “materially strong result” in a post-earnings note, adding that the beat comes against a backdrop of broad investor skittishness around large-cap pharma earnings this quarter, with multiple peers reporting pipeline setbacks and margin compression in recent weeks. From a valuation perspective, the Winrevair performance is the most meaningful takeaway for long-term investors, as it de-risks a core component of Merck’s post-Keytruda growth thesis. Consensus estimates had pegged Winrevair Q1 sales at $440 million, so the 19% upside beat suggests the therapy is on track to hit peak sales of $4.2 billion by 2030, per sector consensus, which would offset roughly 15% of the expected revenue decline from Keytruda in the first three years post-patent expiry. The strong uptake of Keytruda Qlex is another critical win for Merck’s risk mitigation strategy. Sector analysts estimate that the subcutaneous formulation will retain 30% to 40% of Keytruda’s current patient base after 2028, as patients and providers prioritize the convenience of 2-minute in-clinic or at-home administration over cheaper biosimilar alternatives that will only be available for the older intravenous formulation initially. This could cut projected Keytruda revenue declines post-2028 by nearly half, according to Goldman Sachs research. The underperformance of Ohtuvayre and Capvaxive is a modest headwind, but not material to the long-term thesis, as both assets combined represent less than 2% of projected 2026 total revenue. The modest guidance upgrade also signals management is taking a cautious approach to 2026 forecasts, leaving room for further upside as the Terns Pharmaceuticals acquisition closes and its lead NASH and oncology assets progress through clinical trials. The sub-1% post-earnings share gain reflects that a large share of the Q1 beat was already priced in, given MRK’s 5.4% YTD rally ahead of earnings. Lingering concerns over the Keytruda patent cliff remain the primary valuation overhang, though the Q1 results reinforce that Merck’s new product strategy is gaining tangible traction. Investors can use discounted cash flow (DCF) modeling to test their MRK valuation thesis, incorporating assumptions around Winrevair penetration rates and Keytruda franchise retention post-2028.
