Key Takeaways
Thesis: Alnylam is the founder and undisputed leader of RNA interference (RNAi) therapeutics globally. Its flagship Amvuttra/Onpattro franchise (for TTR amyloidosis) posted record Q1 2026 TTR series revenue of $910M (YoY +153%), propelling the company to its first-ever quarterly GAAP net profit of $206M — a landmark signaling the transition from R&D cash-burn phase to profitable harvest phase. Full-year guidance of $4.9-5.3B in product revenue implies YoY +32-43%. The pipeline features zilebesiran (hypertension) and vutrisiran cardiomyopathy label expansion as the next growth catalysts.

Scenario Analysis (Educational Illustration Only):
- Bear Case: Forward PE ~30x — TTR growth decelerates below 20% + pipeline delays
- Base Case: Forward PE ~42x — Full-year guidance midpoint of $5.1B delivered + positive zilebesiran data
- Bull Case: Forward PE ~52x — TTR reaches $5.3B upper end + zilebesiran NDA filing + cardiomyopathy label expansion approved
Note: These are arithmetic scenarios derived from publicly disclosed guidance ranges and growth assumptions, not price forecasts or investment recommendations.
Key Risks:
- TTR franchise concentration — Q1 TTR revenue represents 88% of total product revenue
- Competition intensifying — Ionis (eplontersen) and BridgeBio (acoramidis) competing in the TTR space
- Pipeline Phase 3 risk — Zilebesiran hypertension clinical trial remains a binary event
- Elevated valuation — Forward PE ~38x prices in substantial growth
- U.S. drug pricing policy — IRA Medicare negotiations could impact long-term pricing power

Core Technology
Alnylam is the global pioneer in RNA interference (RNAi) therapeutics. Its technology platform uses small interfering RNA (siRNA) to silence specific gene expression, treating diseases at their genetic root. The discovery of this mechanism earned Andrew Fire and Craig Mello the 2006 Nobel Prize in Physiology or Medicine.

| Q2 2025 | $813 | $728 | $76 | $0.57 | ~86% | ~$330 |
| Q3 2025 | $942 | $860 | $145 | $1.08 | ~87% | ~$340 |
| Q4 2025 | $1,100 | $996 | $314 | $2.35 | ~87% | ~$350 |
| Q1 2026 | $1,170 | $1,036 | $206 | $1.99 | ~88% | ~$370 |
Note: Q2 2024 through Q3 2025 data compiled from public filings and third-party aggregations; may contain rounding differences. Q1 2026 is the latest official data.
Key Observations:
- Product revenue grew from $429M (Q2 2024) to $1,036M (Q1 2026) = +141% in just 8 quarters
- Q1 2026 product revenue of $1,036M set an all-time high — YoY +121%, with TTR series at $910M (+153%)
- From persistent losses to stable profitability: Q1 2025 still posted a -$18M loss; Q1 2026 generated $206M GAAP profit
- EPS trajectory: from -$1.44 (Q2 2024) to +$1.99 (Q1 2026) — a dramatic inflection
- Gross margin continues improving: from ~84% to ~88%, driven by scale effects and product mix optimization
- R&D investment maintained (~$370M/quarter), but revenue growth far outpaces R&D spending growth
Balance Sheet
| Metric | Data | Source |
|---|---|---|
| Cash & Equivalents | $2.72B | Official filing |
| Short-Term Debt | ~$200M | Official |
| Long-Term Debt | $2.51B | Official |
| Total Debt | $2.7B | Calculated |
| Net Cash / Net Debt | +$219.5M net cash | Calculated |
| Shareholders' Equity | $789M | Official |
| Debt/Equity | 341.9% | Calculated |
| Free Cash Flow (FY2025) | $465M | Official |
Key Assessment:
- Net cash is positive ($219.5M): Despite $2.7B in absolute debt, cash reserves of $2.72B provide full coverage — no near-term solvency pressure
- D/E of 341.9% appears extreme but is primarily because accumulated historical losses have depressed shareholders' equity ($789M); this will improve rapidly with sustained profitability
- FY2025 FCF of $465M represents the first year of positive FCF — a milestone; FY2026 FCF is expected to reach $1B+
- FY2025 net income: $314M (YoY +213%) — profitability scaling rapidly
- Interest coverage is adequate: current quarterly operating profit >$200M vs annualized interest expense ~$150M, yielding >5x coverage
Conclusion: The balance sheet is in rapid transition from "R&D-phase burden" to "profitable-phase health." Net positive cash is the key signal — Alnylam no longer depends on financing to sustain operations.

Industry Context
Alnylam is at the S-curve commercialization acceleration phase of RNAi therapeutics:
- Q1 2026 TTR revenue of $910M (YoY +153%) confirms explosive growth
- Full-year guidance of $4.9-5.3B implies +32-43% YoY
- First GAAP profit in Q1 2026 ($206M) confirms the profitability inflection point
- The company is transitioning from a rare disease RNAi company to a chronic disease + rare disease dual-track RNAi platform. The TTR franchise has proven commercialization capability; zilebesiran (hypertension) represents the critical leap from rare disease to mass market.

Method 2: P/E Valuation
| Metric | Current | Fair Range | Assessment |
|---|---|---|---|
| Trailing PE | ~54x | 40-60x (high-growth biopharma) | Within fair range |
| Forward PE | ~38x | 30-50x | Fair to slightly low |
| FY2027E EPS | ~$10 (est.) | — | If delivered, forward PE drops to ~30x |
PE-Derived Fair Value: FY2027E EPS $10 x 35x fair PE = $350
Method 3: EV/Revenue
| Metric | ALNY | Peer Average | Assessment |
|---|---|---|---|
| EV/Revenue (TTM) | ~10x | 8-15x (high-growth biopharma) | Fair |
| EV/Revenue (FY2026E) | ~7.8x | — | Slightly low (growth supports higher multiple) |
EV/Revenue Fair Value: $5.1B x 9x = EV $45.9B = $340/share
Three-Method Summary
| Method | Implied Price | vs Current |
|---|---|---|
| DCF | $310 | +5% |
| P/E | $350 | +19% |
| EV/Revenue | $340 | +15% |
| Average | $333 | +13% |
Valuation Conclusion: The current price of $295 sits in the lower portion of the fair value range. If FY2026 guidance is met ($5.1B+) and zilebesiran data reads positively, upside potential is 15-40%. However, the valuation is not cheap — TTR growth deceleration or pipeline failures would trigger PE compression.
