What Happened

Novo Nordisk released its FY2025 financial report today (Feb 3, 2026), one day ahead of the scheduled earnings call. The report contains a material negative surprise:

1

Revenue Guidance Reversed from Growth to Decline

2026 guidance: -5% to -13% adjusted sales growth at CER. This is a dramatic reversal from +10% growth achieved in 2025.

Management: "Adjusted sales growth for 2026, which excludes revenue from the reversal of 340B provisions, is expected to be -5 to -13% at CER."

2

MFN Agreement Creates Structural Pricing Ceiling

The "Most Favoured Nations" agreement with the US Administration is the primary driver of the revenue decline. This affects:

  • Medicare Part D pricing (pilot program mid-2026)
  • Medicaid price cuts
  • Direct-to-patient self-pay channel ($199/month Wegovy offers)
3

Q4 2025 Results Already Show Contraction

This is not a forecast — contraction is already happening:

  • Total sales: -8% YoY
  • US Operations: -7% at CER
  • Wegovy: -4% Q4 (vs +41% full-year) — severe deceleration
  • Operating profit: -14% YoY

How Our Signals Changed

We ran targeted updates on the Gravy Gauge lens. Here's what changed — and what didn't.

Revenue Durability
FRAGILE
DOWNGRADED

Management guidance for -5% to -13% revenue decline is a categorical change from 'at risk' to 'actively contracting.' MFN agreement creates structural pricing ceiling.

Regulatory Exposure
ELEVATED
CONFIRMED

MFN agreement and compounding are materializing AS EXPECTED. Not worse than anticipated. Rating unchanged.

Competitive Position
CONTESTED
CONFIRMED

Market share loss 9.3pp (slightly worse than 9pp estimate). Competition continuing as predicted. Rating unchanged.

Why We Downgraded Revenue Durability

Signal Change
CONDITIONAL → FRAGILE

Our Feb 2 analysis rated REVENUE_DURABILITY as CONDITIONAL — revenue was real but dependent on navigating the 2026-2027 transition period. The key monitoring trigger was "Q4 2025 Earnings: Bear case = further guidance cuts."

The bear case has materialized. Revenue is now explicitly guided to decline, not just slow. This moves from "at risk of slowing" to "actively contracting."

What drove the change:

1
Revenue guidance reversed

-5% to -13% decline (was +10% growth)

2
MFN agreement quantified

Now the primary driver of decline, larger impact than previously modeled

3
Q4 already contracting

US -7%, Wegovy -4% — not forecast, reality

4
Market share loss exceeded estimates

9.3pp actual vs 9pp estimated

5
Patent expiry — new IO headwind

Semaglutide molecule expiring in certain international markets, not previously quantified

What Remained Unchanged

REGULATORY_EXPOSURE: ELEVATED

Regulatory is materializing as expected, not worse. MFN agreement was anticipated. Compounding continues. IRA timing unchanged. No surprise beyond our prior assessment.

COMPETITIVE_POSITION: CONTESTED

Market share erosion continuing but not catastrophically accelerating. Lilly competition intensifying as expected. Novo retains manufacturing scale. Pipeline still in development.

Updated Investment Thesis

From Value Rotation to Restructuring Story

Previous assessment: NVO was a "value rotation candidate" — a former growth stock transitioning to mature-stage competitive dynamics.

Updated assessment: NVO is now a "restructuring story." The distinction: value rotation assumes growth continues at lower rate; restructuring acknowledges revenue is contracting while the company rebuilds competitive position.

Bull Case Now Requires

  • 1. Revenue decline at shallow end (-5%)
  • 2. Wegovy pill creates growth vector
  • 3. CagriSema delivers >20% weight loss
  • 4. Lilly stumbles or delays

Bear Case Scenarios

  • 1. Revenue decline at deep end (-13%)
  • 2. Wegovy pill cannibalizes injectables
  • 3. CagriSema disappoints (<16%)
  • 4. MFN implementation worse than guided

Updated Monitoring Triggers

Q4 2025 Earnings / 2026 GuidanceRESOLVED

Bear case materialized. Signal downgraded CONDITIONAL → FRAGILE.

Q1 2026 Revenue TrajectoryNEW — May 2026

Decline >10%: Maintain FRAGILE. Decline <5%: Consider upgrade to CONDITIONAL.

Wegovy Pill Adoption RateNEW — Quarterly

>100K weekly Rx = partial offset. <30K = cannibalization concern.

CagriSema REDEFINE 4Q1 2026
