ECONOMICS SUMMARY (as of Feb 2026):
WHO BOOKS REVENUE: Novartis (NVS) books 100% of global Leqvio product sales.
FY2025 NVS sales: $1,198M (+59% YoY). Hit blockbuster status in Q4 2025.
WHAT ALNYLAM (ALNY) RECEIVES:
- Tiered royalties of 10-20% on NVS global net sales (escalates with volume)
- FY2025 ALNY royalty revenue: $174M (implying ~14.5% blended rate)
- FY2024 ALNY royalty revenue: ~$92M
THE BLACKSTONE LAYER (critical):
- In Apr 2020, ALNY sold 50% of its Leqvio royalties to Blackstone for $1B
- So of the $174M ALNY receives from NVS, ~$87M goes to Blackstone
- ALNY net retained royalty: ~$87M (effectively ~7% of NVS sales)
- If Leqvio royalties do not reach $1B cumulative by 2029, ALNY retained share drops 5%
WHAT THIS MEANS FOR INVESTORS:
- NVS investors: Leqvio is a growth driver but they bear 100% of costs + pay ~14.5% royalty to ALNY
- ALNY investors: Leqvio is a royalty stream, NOT product revenue. After Blackstone, ALNY keeps ~$87M/yr on a $1.2B drug
- The market sometimes confuses Leqvio as an ALNY franchise drug — it is not. ALNY earns ~7 cents on every dollar of Leqvio sales
RISK: Jan 2026 Paragraph IV certification filed against Leqvio (early generic threat)
HISTORY: Inclisiran was developed by The Medicines Company using ALNY siRNA platform.
NVS acquired The Medicines Company in Jan 2020 for $9.7B (Leqvio was the crown jewel).
