ATTR-CM is a progressively debilitating cardiac condition characterized by amyloid fibril deposits derived from misfolded transthyretin proteins, leading to impaired heart function. The approval of AMVUTTRA in June 2025 allows Alnylam to offer a gene-silencing therapeutic that targets the root cause by reducing transthyretin production in the liver, distinguishing itself from stabilizer therapies that primarily slow disease progression.
Financial Performance and Market Reaction to Recent Developments#
Despite a recent share price dip of -1.22% to $324.79 as of July 28, 2025, Alnylam's market capitalization stands robust at approximately $42.35 billion. The company's earnings per share (EPS) remain negative at -2.1, reflecting ongoing investments in research and development (R&D) and commercialization efforts.

Clinical and Market Impact of AMVUTTRA#
The European approval of AMVUTTRA is underpinned by robust clinical data from the HELIOS-B Phase 3 trial, which demonstrated a 52% reduction in all-cause mortality and a 54% decrease in cardiovascular-related hospitalizations versus placebo over 30 months. These outcomes not only validate the therapeutic efficacy of RNAi technology but also highlight its potential to transform the management of ATTR-CM.
This clinical success positions AMVUTTRA as a differentiated option compared to Pfizer's Vyndaqel, which generated approximately $5.45 billion in global sales in 2024 but operates via transthyretin stabilization rather than gene silencing. Alnylam's mechanism may offer more profound disease modification, potentially translating into better long-term patient outcomes.
Market adoption in Europe is expected to accelerate post-approval, expanding Alnylam’s addressable market. Visible Alpha forecasts ATTR-CM sales reaching approximately $420 million in 2025, significantly contributing to Alnylam's revenue growth.
Competitive Landscape and Strategic Positioning#
Alnylam's RNAi platform offers a novel modality that distinguishes it from competitors relying on protein stabilization or other mechanisms. The company’s broad pipeline, including treatments for polyneuropathy and familial amyloid polyneuropathy, signals sustained innovation and diversification potential.
Pfizer's Vyndaqel remains dominant, but AMVUTTRA's clinical profile and expanded geographic reach could erode market share over time. Additionally, emerging competitors like BridgeBio's Attruby are gaining attention, yet Alnylam's established clinical data and regulatory endorsements provide a competitive moat.
Future Growth Prospects and Pipeline Development#
Analyst consensus projects a compound annual growth rate (CAGR) of 28.11% in revenue through the late 2020s, with revenues potentially reaching $8 billion by 2029. EPS estimates reflect a transition to profitability, with forecasts moving from a negative EPS of -0.63 in 2025 to a positive EPS of $16.06 by 2029.
Alnylam’s pipeline expansion and strategic investments in next-generation RNAi therapeutics are critical to sustaining this growth. The company's capital allocation, with nearly half of revenue reinvested into R&D, aligns with a long-term vision focused on genetic medicine innovation.
Forward Revenue and EPS Estimates#
| Year | Estimated Revenue | Estimated EPS |
|---|---|---|
| 2025 | $2.97B | -$0.63 |
| 2026 | $3.92B | $2.31 |
| 2027 | $5.1B | $7.59 |
| 2028 | $6.3B | $11.28 |
| 2029 | $8.0B | $16.06 |
