Eli Lilly's New Highs Mask Valuation and Competitive Headwinds

What happened

Eli Lilly's stock has broken out to new highs, driven by optimism over its dominant obesity drug franchise and the anticipated Q2 launch of its oral obesity drug, which is expected to lower patient barriers and accelerate global penetration. This surge reflects bullish sentiment from articles highlighting Lilly's momentum and diversified pipeline as buffers against risks like generics competition and price wars in ex-U.S. markets. However, the DeepValue master report critically assesses that at ~$1,084, LLY's valuation—53x trailing EPS and EV/EBITDA of 66—already prices in sustained high GLP-1 growth, with a 'POTENTIAL SELL' rating due to overvaluation and limited upside. Key vulnerabilities include intensifying price competition from Novo Nordisk's oral Wegovy pill, policy-driven net price caps from TrumpRx and Medicare deals, and payer friction exemplified by CVS Caremark's formulary changes. Despite a robust pipeline, the report warns that without evidence of GLP-1 economics holding up better than expected, the risk-reward profile favors trimming or avoiding new positions until either the share price resets or fundamentals improve.

Implication

The breakout to new highs underscores market enthusiasm but overlooks critical risks highlighted in the DeepValue report, where LLY's concentration in GLP-1 drugs exposes it to pricing erosion and share loss from Novo Nordisk's aggressive oral launch. With valuation metrics like a PE of 53x embedding near-perfect execution, any slowdown in GLP-1 revenue growth below 20% or faster-than-expected net price declines could trigger significant multiple compression. The upcoming oral drug launch must overcome efficacy and pricing hurdles to gain meaningful share, yet early signals from Wegovy pill's lower pricing and superior weight loss data suggest a tough competitive landscape. Moreover, policy shifts and payer dynamics are accelerating commoditization risks, making it prudent to await a more attractive entry point around $850 or clearer signs of pricing resilience. Therefore, maintaining a disciplined approach by reducing exposure or staying sidelined is advisable until the risk-reward skew improves.

Thesis delta

The news article does not materially alter the DeepValue thesis; it reinforces Lilly's growth narrative but also echoes the same competitive and pricing risks that underpin the 'POTENTIAL SELL' call. Thus, the thesis remains unchanged: LLY is overvalued with asymmetric downside risks, and investors should avoid new positions until either the price corrects to ~$850 or evidence emerges that GLP-1 economics can withstand mounting headwinds better than currently anticipated.
