Merck's Bullish Article Overlooks Critical Risks, DeepValue Analysis Urges Neutral Stance

What happened

A recent Seeking Alpha article rates Merck a buy, highlighting strong earnings growth, rising cash flow, and a low forward P/E of 13.8x compared to peers. However, the DeepValue master report cautions that Merck's heavy dependence on Keytruda, which contributed $29.5B in 2024 revenue, creates concentration risk amid explicit U.S. IRA price setting in 2027 and loss of exclusivity in 2028. Gardasil volatility in China further weighs on growth, despite management's pipeline of over 20 late-stage assets targeting $50B in revenue by the mid-2030s. The stock trades near its FCF-based DCF intrinsic value, implying limited margin of safety and a balanced risk/reward profile. Thus, while surface metrics appear attractive, deeper analysis reveals significant headwinds that could erode long-term earnings if pipeline execution falters or policy risks materialize.

Implication

Merck's low valuation and strong free cash flow offer some downside protection, but the concentration in Keytruda exposes it to severe revenue erosion from U.S. IRA price negotiations and biosimilar competition post-2028. Pipeline success is essential to diversify away from Keytruda, yet clinical failures or poor commercial launches could undermine this effort, while Gardasil's China weakness adds near-term uncertainty. Investors must closely monitor quarterly sales trends, IRA implementation details, and key regulatory milestones for assets like clesrovimab and Capvaxive to gauge future prospects. Without clear outperformance in these areas, the stock lacks a compelling margin of safety, suggesting a wait-and-see approach is prudent. Ultimately, Merck represents a balanced but risky proposition, requiring vigilant oversight rather than aggressive positioning.

Thesis delta

The Seeking Alpha article does not shift the investment thesis, as it merely repackages optimistic narratives without addressing the material risks documented in SEC filings, such as IRA timelines and Gardasil volatility. Therefore, the thesis remains unchanged: Merck is a quality company facing significant concentration and policy headwinds, warranting a neutral stance until pipeline delivery or policy clarity improves.
