Given Company's Founding Timeline

Year established

2002 (June 14, 2002, specifically).

Original location

Cambridge, Massachusetts, U.S.

Founding team members

The company was founded by a powerhouse group of scientists and investors, including Nobel Laureate Phillip Sharp, Paul Schimmel, David Bartel, Thomas Tuschl, and Phillip Zamore. Investors Christoph Westphal and John Kennedy Clarke were also key, and John Maraganore served as the founding CEO.

Initial capital/funding

The company secured a $17 million Series A funding round in 2002. This was quickly followed by a crucial merger in 2003 with the German company Ribopharma AG, which brought in an additional $24.6 million in funding from private-equity firms.

Given Company's Evolution Milestones

Given Company's Transformative Moments

The company's trajectory wasn't a straight line; it was a series of high-stakes bets on a technology-RNA interference (RNAi)-that many thought was defintely too complex for therapeutics. The biggest transformative decision was simply sticking with RNAi when the wider pharma industry, including early partners like Novartis and Roche, pulled back around 2010.

The shift from a platform company to a fully integrated commercial one was another huge pivot. This meant controlling everything from discovery to sales, rather than just licensing the technology. The 2011 'Alnylam 5x15' strategy was the roadmap for this. One clean one-liner: RNAi delivery was the great challenge, and they solved it.

Key transformative decisions that shaped the current company:

• Solving Delivery: The breakthrough in delivery technology, specifically the GalNAc conjugation, was crucial. This allowed for subcutaneous (under the skin) dosing, making drugs like AMVUTTRA and OXLUMO possible, and targeting the liver efficiently.
• Committing to Commercialization: Unlike many early biotechs, Alnylam chose to build its own commercial infrastructure, starting with ONPATTRO in 2018. This decision is why they are now guiding for over $2.95 billion in product revenue for 2025, capturing the full value of their drugs.
• The ATTR-CM Expansion: The 2025 U.S. approval of AMVUTTRA for ATTR-CM (a form of heart disease) is the single biggest near-term growth driver. The TTR franchise revenue alone is projected to be between $2.475 billion and $2.525 billion for the year, showing the scale of this opportunity. Here's the quick math: Q3 2025 total TTR net product revenues were $724 million, a 135% growth over the prior year, so the momentum is real.

The company's current strategic focus, 'Alnylam P5x25,' aims to cement its status as a top-tier biotech, delivering on its promise of sustainable profitability. This means advancing late-stage programs like zilebesiran for hypertension and nucresiran for hATTR-PN, which have multibillion-dollar commercial potential beyond their current rare disease portfolio.

Alnylam Pharmaceuticals, Inc. (ALNY) How It Works

Alnylam Pharmaceuticals, Inc. operates by pioneering a completely new class of medicine called RNA interference (RNAi) therapeutics, which directly targets and silences the messenger RNA (mRNA) that carries instructions for making disease-causing proteins, essentially turning off a faulty gene at its source. This approach allows the company to treat the root cause of debilitating, often genetic, diseases rather than just managing symptoms, and their commercial success is evident in the projected 2025 total net product revenues of between $2.95 billion and $3.05 billion.

Alnylam Pharmaceuticals, Inc.'s Product/Service Portfolio

The company's commercial portfolio is anchored by its TTR franchise, which is expected to generate between $2.475 billion and $2.525 billion in net product revenues for the 2025 fiscal year, plus a growing Rare franchise and key licensed products.

Alnylam Pharmaceuticals, Inc.'s Operational Framework

The core of Alnylam's operation is translating the Nobel Prize-winning science of RNA interference (RNAi) into stable, deliverable medicines. This isn't just lab science; it's a highly industrialized process that creates real value for patients and stakeholders.

• Gene Silencing by Design: Alnylam designs small interfering RNA (siRNA) molecules to match the specific messenger RNA (mRNA) of a disease-causing gene. Think of the siRNA as a molecular pair of scissors.
• Targeted Delivery: The biggest challenge in RNAi was getting the siRNA to the right cells. The company solved this with its proprietary ESC-GalNAc conjugate delivery platform, which chemically links the siRNA to a GalNAc ligand. This ligand acts like a homing beacon, specifically guiding the drug to receptors on liver cells, allowing for simple, subcutaneous injections.
• Catalytic Action: Once inside the cell, the siRNA joins the RNA-induced Silencing Complex (RISC) and finds the target mRNA. It then cleaves (cuts) and degrades the mRNA, preventing the production of the harmful protein. Importantly, this process is catalytic, meaning one siRNA-RISC complex can destroy many copies of the target mRNA.
• Pipeline Expansion: The company is rapidly expanding beyond liver-expressed genes, with over 25 high-value programs expected in the clinic by the end of 2025, exploring delivery to other tissues like the central nervous system (CNS) and the eye.

Here's the quick math: silencing the gene means the disease-causing protein is never made, which is a fundamentally different and often more effective treatment strategy than traditional drugs that just block the protein after it's already circulating.

Alnylam Pharmaceuticals, Inc.'s Strategic Advantages

Alnylam's market success isn't luck; it's built on a defensible, multi-layered advantage that goes beyond its initial product approvals. They are defintely a category leader.

• Pioneering RNAi Platform: The company has a 20+ year head start, investing over $4 billion in RNAi technology to date, which has resulted in a deep intellectual property moat around the core siRNA chemistry and delivery systems.
• TTR Franchise Leadership: The Total TTR franchise, driven by AMVUTTRA, is positioned for continued dominance, especially in the large and underserved ATTR-CM market, which is estimated to include 300,000 patients worldwide.
• Proven Commercial Engine: They have successfully transitioned from an R&D-focused entity to a fully integrated biopharma company, achieving a key financial goal of non-GAAP profitability in 2025. This commercial engine is now self-sustaining and scalable.
• Pipeline Depth and Diversification: With a robust pipeline that includes late-stage programs like nucresiran for ATTR-CM and zilebesiran for hypertension, the company is mitigating the binary risk common in biotech. The zilebesiran program alone is anticipated to expand gross margins due to the absence of royalty burdens.

Alnylam Pharmaceuticals, Inc. (ALNY) How It Makes Money

Alnylam Pharmaceuticals, Inc. generates revenue primarily by commercializing its portfolio of RNA interference (RNAi) therapeutics, which are highly specialized, high-priced medicines for rare and prevalent diseases, plus significant income from strategic collaboration and royalty agreements.

The company's financial engine is currently being supercharged by the successful launch and uptake of its Transthyretin (TTR) amyloidosis franchise, specifically AMVUTTRA, which is driving a major shift toward sustainable profitability in the 2025 fiscal year.

Alnylam Pharmaceuticals' Revenue Breakdown

As of the third quarter of 2025, Alnylam reported total revenues of nearly $1.25 billion, a massive 149% increase year-over-year. Here's the quick math on where that money is coming from, showing the TTR franchise's dominance and the one-time boost from partnerships.

The TTR Franchise, which includes AMVUTTRA and ONPATTRO, brought in $724 million in Q3 2025 alone. This is defintely the core business, but you can't ignore the collaborations. The spike in Collaboration & Royalties revenue ($398 million) was largely due to a single, substantial milestone payment of $300 million from the Roche partnership for the zilebesiran program.

Business Economics

The underlying economics of Alnylam are typical of a successful, late-stage biotechnology firm: high upfront research costs followed by high-margin product sales, especially for orphan drugs. Their strategy is to price for value in rare disease markets.

• Premium Pricing Strategy: The annual list price for AMVUTTRA is approximately $476,000 per patient. This is a strategic premium, nearly double the cost of competitors like Pfizer's tafamidis, which is justified by its differentiated RNAi mechanism of action and convenient quarterly administration schedule.
• High Gross Margins: The Gross Margin on product sales remains strong at 77% as of Q3 2025, even though this is a slight dip from 80% the prior year due to rising royalty obligations on AMVUTTRA sales. A 77% margin gives the company immense financial leverage to reinvest in its pipeline.
• Payer Access Advantage: AMVUTTRA's administration via Medicare Part B (physician-administered medicines) is a critical economic factor, as approximately 75% to 80% of eligible ATTR-CM patients are covered by Medicare. This structure can incentivize prescription and simplify patient access compared to Part D (pharmacy-benefit) drugs.
• Value-Based Agreements: The company uses innovative value-based agreements linked to clinical outcomes to ensure broad patient access and predictability for payers.

Alnylam Pharmaceuticals' Financial Performance

The company is transitioning from a high-growth, R&D-intensive model to a commercially profitable one, hitting a significant milestone in 2025.

• Profitability Achieved: Alnylam reported a GAAP net income of $251 million for Q3 2025, a substantial turnaround from a net loss in the prior year period. The Non-GAAP net income was even higher at $396 million.
• Expense Profile: Operating expenses are rising, which is expected during a major product launch and pipeline advancement. Non-GAAP Research & Development (R&D) expenses were $310 million in Q3 2025 (up 23% YoY), driven by the ZENITH Phase 3 trial for zilebesiran in hypertension and other late-stage programs. Non-GAAP Selling, General, and Administrative (SG&A) expenses were $263 million (up 35% YoY), reflecting the significant investment in the AMVUTTRA launch.
• Liquidity: The balance sheet remains solid, with cash, cash equivalents, and marketable securities totaling $2.7 billion as of September 30, 2025. This cash position provides a strong buffer to fund the expensive late-stage pipeline.
• 2025 Outlook: The company raised its full-year 2025 total net product revenue guidance to a range of $2.95 billion to $3.05 billion, underscoring confidence in the AMVUTTRA launch trajectory. This is a huge jump.
