Current: $850 · PT: $950
Investment Thesis
Dominant GLP-1 franchise with Mounjaro/Zepbound driving unprecedented growth. Pipeline includes oral GLP-1 (orforglipron, PDUFA Mar 2026) and triple agonist retatrutide. Alzheimer's drug Kisunla adds diversification.
Bull Case
Obesity market larger than expected ($150B+ TAM). Oral GLP-1 opens maintenance market. Manufacturing investments create durable competitive advantage. Retatrutide could be best-in-class with ~30% weight loss.
Bear Case
Competition from Novo Nordisk intensifying. Pricing pressure from payers/government. Manufacturing scale-up execution risk. Safety signals in retatrutide (dysesthesia).

Open Debates (2)
Underappreciated Growth Driver: Kisunla (donanemab) Alzheimer's TAM
Bull
Kisunla has a key differentiator: treatment discontinuation. Unlike Leqembi (indefinite treatment), Kisunla can be stopped once amyloid is cleared — making the treatment course finite and more palatable for payers. Alzheimer's affects 7M Americans; even 5% penetration at $26K/year = $9B. Blood-based diagnostics (PrecivityAD) are eliminating the PET/CSF bottleneck. The slow Leqembi launch reflected infrastructure issues, not demand — those are being resolved. LLY's commercial engine (built for GLP-1 scale) will outperform Eisai's.
Bear
Leqembi's slow launch (<$1B) suggests anti-amyloid demand is limited. ARIA safety concerns limit to specialist settings. Payer resistance remains high. $5B peak may be more realistic than $15B+.
Conviction: 5/5
Underappreciated Risk: GLP-1 Class Safety Signals at Current Valuation
Bull
GLP-1s have been used for 20+ years in diabetes with well-characterized safety. The class is being used in millions of patients with strong real-world safety data. Thyroid cancer signals have not been confirmed in humans.
Bear
LLY trades at 50-60x forward earnings. The obesity franchise (Mounjaro + Zepbound) is projected at $65B+ peak. ANY class safety signal — thyroid cancer confirmation, pancreatitis increase, muscle loss concerns, psychological effects — would crater the stock. The valuation has zero margin of safety for a negative surprise. Compounding pharmacies are eroding brand pricing. IRA negotiations will eventually target GLP-1s. At this multiple, even a 10% downward revision to peak sales estimates means a 20-30% stock decline.
Conviction: 5/5
Would change view: The market treats GLP-1 safety as fully characterized. But the obesity population (vs diabetes) is younger, healthier, and treated for decades. Long-term safety data in this population does not exist.
