Executive Summary
Investment Thesis (3 Sentences)
Novo Nordisk is the dominant player in the GLP-1 obesity and diabetes market, possessing a durable competitive moat built on decades of manufacturing expertise, the largest clinical trial database for incretin therapies, and a deep pipeline of next-generation treatments. The stock has declined 35% from its 2025 peak of $91.28 to $59.43 due to concerns about compounding, competitive intensity from Eli Lilly, and a transition in growth expectations from "explosive" to merely "excellent" (10-15% topline). At 15.8x TTM earnings with 44%+ operating margins, 71% ROE, and a 3.7% FCF yield, this is a rare opportunity to buy a world-class franchise at a reasonable price during a period of temporary uncertainty.

Phase 0: Opportunity Identification (Klarman)
Why Does This Opportunity Exist?
Sentiment Shift from "Explosive" to "Merely Excellent"
- Market priced NVO for 25-30% perpetual growth
- 2025 guidance lowered to 8-11% sales growth
- Stock declined 35% despite fundamentals remaining strong
Compounding Disruption Fears
- Estimated 1M+ patients on compounded GLP-1s in US
- Creates short-term Wegovy prescription pressure
- But: FDA removed semaglutide from shortage list, compounding now illegal
Eli Lilly Competitive Concerns
- Tirzepatide (Mounjaro/Zepbound) showing strong efficacy
- Market fears "winner take all" outcome
- Reality: Market large enough for multiple winners
Medicare Pricing Pressure (IRA)
- Maximum Fair Price accepted for semaglutide in Medicare Part D
- Effective January 2027
- Low single-digit impact on global sales
CEO Transition
- Lars Fruergaard Jorgensen stepped down August 2025
- Mike Doustdar (internal promotion) now CEO
- Some uncertainty during transition
Source of Mispricing
The market is treating temporary headwinds (compounding, single-year guidance, CEO change) as permanent impairment of a franchise that:
- Has grown revenue 23% CAGR for 5 years
- Maintains 44%+ operating margins
- Has 50%+ global GLP-1 market share
- Owns the largest manufacturing footprint
- Invested $16.5B in Catalent to expand capacity
This is exactly the type of high-quality business experiencing temporary turbulence that Buffett describes as an ideal buying opportunity.
Phase 1: Risk Analysis (Inversion)

Inversion Section (Required)
How could this investment lose 50%+ permanently?
A safety signal emerges showing GLP-1s cause serious long-term harm (cancer, cardiovascular, neurological). This would destroy the entire franchise. Probability: <5% given 33M patient-years of real-world exposure and clean safety profiles in trials.
Eli Lilly's oral tirzepatide + Amgen's AMG 133 prove so superior that NVO loses substantial market share AND cannot respond with competitive pipeline. Probability: <10% given NVO's pipeline depth (CagriSema, amycretin, triagonist).
Global healthcare systems implement severe price controls that make GLP-1 economics unviable. Probability: <10% given pricing power and demand elasticity.
What would make me sell immediately (non-price triggers)?
- FDA or EMA issues black box warning on semaglutide
- CagriSema Phase III fails AND amycretin disappoints
- New CEO significantly changes capital allocation (excessive M&A, dividend cut)
- Evidence of accounting fraud or material misrepresentation
If I were short this stock, what's my 3-sentence bear case?
"NVO is a one-drug company (semaglutide) facing patent expiry in 2026 internationally and fierce competition from Eli Lilly's superior dual GIP/GLP-1 mechanism. The obesity market is overhyped because most patients discontinue within a year and payors will increasingly refuse coverage for what they view as lifestyle drugs. At 16x earnings with 8-11% growth guidance, NVO is priced for perfection while delivering disappointment."
Can I state the bear case better than the bears? Yes - and I believe it's largely wrong because: (1) semaglutide US patent runs to 2032, (2) NVO has multiple mechanisms beyond semaglutide, (3) discontinuation improves with longer-acting formulations and better tolerability, (4) obesity is now recognized as a chronic disease with cardiovascular benefits.
Phase 2: Financial Analysis
Return Metrics (10-Year DuPont Analysis)
| Year | Net Margin | Asset Turnover | Equity Mult. | ROE |
|---|---|---|---|---|
| 2024 | 34.8% | 0.69x | 3.25x | 70.4% |

| 2020 | 32.9% | 0.83x | 1.82x | 41.2% |
Key Insight: ROE expanded from 41% to 71% driven by:
- Margin expansion (32.9% to 34.8%)
- Increased leverage for growth (1.82x to 3.25x) - still conservative
- Operating leverage on fixed costs

Relative Valuation
| Company | P/E | EV/EBITDA | Operating Margin | Growth |
|---|---|---|---|---|
| Novo Nordisk | 15.8x | 11.4x | 44% | 10-15% |
| Eli Lilly | 45.0x | 35.0x | 35% | 20-25% |
| AstraZeneca | 20.0x | 13.0x | 28% | 8-10% |
| Merck | 14.0x | 10.0x | 32% | 5-7% |
| Pfizer | 10.0x | 8.0x | 25% | 0-3% |
Observation: NVO trades at a significant discount to Eli Lilly despite similar market position and better margins. Even vs traditional pharma peers, the premium for superior growth/margins is minimal.
Phase 3: Moat Analysis
Moat Sources
| Moat Type | Strength | Evidence | Duration |
|---|---|---|---|
| Manufacturing Scale | WIDE | $16.5B Catalent + existing = largest fill-finish capacity | 10+ years |
| Clinical Database | WIDE | 33M patient-years; largest GLP-1 outcomes data | 15+ years |
| Regulatory Expertise | WIDE | First-mover in obesity approvals globally | 10+ years |
| Brand/Reputation | NARROW | Ozempic/Wegovy recognized; but LLY catching up | 5+ years |
| Pipeline Depth | WIDE | CagriSema, amycretin, triagonist, oral sema | 10+ years |
Competitive Position
Global GLP-1 Market Share (Volume):
- Novo Nordisk: 68% (International), 50%+ (US)
- Eli Lilly: 25-30% (growing)
- Others: <10%
Manufacturing Moat: NVO has invested over $50B in manufacturing capacity over the past decade. The Catalent acquisition ($16.5B) added:
- 3 fill-finish facilities
- Significant peptide manufacturing capability
- Ability to meet 3-5 year demand projections
This capacity cannot be replicated quickly - it takes 3-5 years to build and qualify new peptide manufacturing.
Moat Durability Assessment
| Threat | Severity (1-5) | Timeline | Company Mitigation |
|---|---|---|---|
| Eli Lilly tirzepatide | 4 | Now | CagriSema (dual mechanism), amycretin |
| Amgen AMG 133 | 3 | 2027+ | Pipeline diversity; outcomes data |
| Oral GLP-1 competition | 3 | 2026+ | First-mover with oral sema 25mg |
| Patent expiry (IO) | 3 | 2026 | US patent to 2032; next-gen products |
| Biosimilar entry | 2 | 2032+ (US) | Brand loyalty; manufacturing scale |
10-Year Moat Trajectory: Likely STABLE to WIDENING
- Manufacturing advantage widening
- Pipeline refreshing franchise
- Clinical data advantage compounds
- Main risk: LLY achieving parity
Phase 4: Management & Incentive Analysis

|---|---|---|
| Organic CapEx | DKK 170B | Excellent - capacity moat |
| Dividends | DKK 150B | Good - 45% payout, growing |
| Buybacks | DKK 85B | Good - below intrinsic |
| M&A | DKK 130B | Good - Catalent strategic |
| Debt Paydown | Minimal | Appropriate given low leverage |
Grade: A
Insider Ownership
- Novo Holdings (foundation) owns majority voting control
- Insiders own <1% of economic interest
- Foundation alignment: long-term, patient capital
- No concerning insider sales
Compensation Analysis
CEO compensation is reasonable relative to peers and tied to:
- Operating profit growth
- Revenue growth
- TSR vs peers
- ESG metrics
Vesting periods are 3+ years, encouraging long-term thinking.

Summary
Novo Nordisk represents a rare opportunity to acquire a world-class pharmaceutical franchise at a reasonable price. The company dominates the fastest-growing therapeutic category (GLP-1s), boasts industry-leading margins (44%+), and has multiple shots on goal with its pipeline. The 35% decline from peak prices reflects temporary headwinds (compounding, single-year guidance miss) rather than permanent impairment.
Terry Smith's 6.5% position in Fundsmith reflects the quality-at-reasonable-price thesis that value investors should embrace. At $59.43 with 21% margin of safety to our fair value estimate of $75, NVO is an ACCUMULATE. Scale to a full position at $50 or below.
