The Bottom Line

Thesis Validated

Eli Lilly delivered exactly what we expected: strong execution within the existing risk framework. All three signals remain unchanged. This is a CONFIRMATION, not a thesis change. The competitive divergence vs Novo Nordisk has widened dramatically (LLY +23-27% guidance vs NVO -5% to -13%), but the fundamental risk profile — tirzepatide concentration, regulatory exposure, switching cost constraints — persists.

Signal Status After Earnings

REVENUE_DURABILITY
CONDITIONAL

Beat-and-raise confirms operational execution. Tirzepatide concentration at 56% — within prior 57-63% estimate. Volume-price trade-off working (-7% pricing, +50% volume).

REGULATORY_EXPOSURE
ELEVATED

Government $50/month Medicare deal trades uncertainty for margin compression. MDL 3094 litigation (3,063 claims) unchanged. Orforglipron FDA date extended to April 10 (immaterial shift).

COMPETITIVE_POSITION
DEFENSIBLE

Confidence increased from HIGH to VERY HIGH. Competitive divergence vs Novo widened dramatically. But weak switching costs still cap moat ceiling — label unchanged.

What Beat Expectations

1
Q4 2025 Revenue

$19.3B actual vs $18.0B consensus (+$1.3B beat, +43% YoY)

2
2026 Revenue Guidance

$80-83B guidance vs $77.6B consensus (+$2.4-5.4B above)

3
Tirzepatide Performance

Mounjaro $7.4B (+110%), Zepbound $4.3B (+123%) — combined $11.7B Q4

4
Pipeline Progress

Retatrutide Phase 3: 71.2 lbs weight loss; Orforglipron submitted U.S., Japan, EU

The Novo Nordisk Divergence

The contrast between Eli Lilly and Novo Nordisk could not be more stark. On back-to-back days:

Eli Lilly (Feb 4)
  • • 2026 guidance: +23% to +27% growth
  • • Stock reaction: +7%
  • • Volume growth: +50% U.S.
  • • Manufacturing: Meeting all demand
Novo Nordisk (Feb 3)
  • • 2026 guidance: -5% to -13% decline
  • • Stock reaction: -13%
  • • MFN pressure: Pricing headwind
  • • Market share: Lost 9.3 points

This is perhaps the most dramatic competitive divergence in recent pharmaceutical history. Lilly's manufacturing advantage and pipeline depth are translating to sustained share gains while Novo contracts.

What Didn't Change (And Why It Matters)

Risk Profile Persists

Despite the strong quarter, the fundamental risk factors we identified remain:

Tirzepatide Concentration: 56%

Within our prior 57-63% estimate. Still the highest single-molecule concentration among large-cap pharma. Any regulatory or competitive setback affecting tirzepatide disproportionately impacts overall results.

Regulatory Overhang Unchanged

MDL 3094 litigation (3,063 claims) continues. Texas AG lawsuit active. Orforglipron FDA decision pending (April 10). Government pricing deal trades uncertainty for margin compression — doesn't eliminate exposure.

Weak Switching Costs

Pharmaceutical switching is behavioral (physician habits), not technical lock-in. A superior competitor product could still erode position. This ceiling on moat durability hasn't changed.

Our Update Process

For earnings updates, we run abbreviated discourse — a single analyst round per lens evaluating whether new data changes any signals. If a signal change is proposed, we run full Bullet Hole validation. In this case, all three analysts recommended CONFIRM on their respective signals.
