ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion contains management’s discussion and analysis of our financial condition and results of operations and should be read together with our unaudited condensed consolidated financial statements and the notes thereto included elsewhere in this Quarterly Report on Form 10-Q.

Overview

We are a global commercial-stage biopharmaceutical company developing novel therapeutics based on ribonucleic acid interference, or RNAi. RNAi is a naturally occurring biological pathway within cells for sequence-specific silencing and regulation of gene expression. By harnessing the RNAi pathway, we have pioneered a new class of innovative medicines, known as RNAi therapeutics. RNAi therapeutics are comprised of small interfering RNA, or siRNA, that function upstream of conventional medicines by potently silencing messenger RNA, or mRNA, that encode for proteins implicated in the cause or pathway of disease, thus preventing them from being made. We believe this is a revolutionary approach with the potential to transform the care of patients across a broad range of disease areas and indications. To date, our efforts to advance this revolutionary approach have yielded the approval of six first-in-class RNAi-based medicines: AMVUTTRA® (vutrisiran), ONPATTRO® (patisiran), GIVLAARI® (givosiran), OXLUMO® (lumasiran), Leqvio® (inclisiran) and Qfitlia® (fitusiran).

Our research and development strategy is to target genetically validated genes that have been implicated in the cause or pathway of human disease. We utilize an N-acetylgalactosamine (GalNAc) conjugate approach or lipid nanoparticle (LNP) to enable hepatic delivery of siRNAs. For delivery to the central nervous system, or CNS, and the eye (ocular delivery), we are utilizing an alternative conjugate approach based on a hexadecyl (C16) moiety as a lipophilic ligand. We are also advancing approaches for heart, skeletal muscle and adipose tissue delivery of siRNAs, and we are exploring peptide and antibody-based approaches for targeted siRNA delivery to new tissues. Our focus is on clinical indications where there is a high unmet need, a genetically validated target, early biomarkers for the assessment of clinical activity in Phase 1 clinical trials, and a definable path for drug development, regulatory approval, patient access and commercialization.

In early 2026, we launched our Alnylam 2030 strategy to drive our next era of growth and patient impact, and we currently have six marketed products, including two products that are commercialized by collaborators, and more than 25 clinical programs, including several in late-stage development.

AMVUTTRA is approved in the United States, or U.S., for the treatment of hereditary transthyretin-mediated amyloidosis, or hATTR amyloidosis, with polyneuropathy in adults, in the European Union, or EU, and the United Kingdom, or UK, for the treatment of hATTR amyloidosis in adult patients with stage 1 or stage 2 polyneuropathy, in Japan for the treatment of transthyretin, or TTR, type familial amyloidosis with polyneuropathy, and in multiple additional countries. In March 2025, the United States Food and Drug Administration, or the FDA, approved our supplemental New Drug Application, or sNDA, for AMVUTTRA for the treatment of the cardiomyopathy of wild-type or hereditary transthyretin-mediated amyloidosis in adults to reduce cardiovascular mortality, cardiovascular hospitalizations and urgent heart failure visits. In June 2025, the European Commission, or EC, granted approval of AMVUTTRA for the treatment of wild-type or hereditary transthyretin amyloidosis in adult patients with cardiomyopathy, following a positive opinion from the Committee for Medicinal Products for Human Use of the European Medicines Agency. AMVUTTRA has also been approved by the Brazilian Health Regulatory Agency, or ANVISA, the Japanese Health Authority, or PMDA, the UK’s Medicines and Healthcare Products Regulatory Agency, or MHRA, and Health Canada for the treatment of ATTR amyloidosis with cardiomyopathy. Regulatory reviews continue in other territories.

ONPATTRO is approved in the U.S. for the treatment of the polyneuropathy of hATTR amyloidosis in adults and is also approved in the EU for the treatment of hATTR amyloidosis in adult patients with stage 1 or stage 2 polyneuropathy, in Japan for the treatment of TTR-type familial amyloidosis with polyneuropathy, and in multiple additional countries. In February 2025, ONPATTRO received regulatory approval from ANVISA in Brazil for the treatment of ATTR amyloidosis with cardiomyopathy.

GIVLAARI is approved in the U.S. for the treatment of adults with acute hepatic porphyria, or AHP, in the EU for the treatment of AHP in adults and adolescents aged 12 years and older, and in several other countries. Regulatory filings for givosiran (the generic name of GIVLAARI) in additional territories are pending or planned during 2026 and beyond.

OXLUMO is approved in the U.S. for the treatment of primary hyperoxaluria type 1, or PH1, to lower urinary and plasma oxalate levels in pediatric and adult patients, and in the EU and the UK for the treatment of PH1 in all age groups. OXLUMO has also been approved in several other countries and regulatory filings for lumasiran (the generic name of OXLUMO) in additional territories are pending or planned during 2026 and beyond.

Leqvio (inclisiran) is being developed and commercialized by our collaborator Novartis AG, or Novartis, and has received marketing authorization from the EC for the treatment of adults with hypercholesterolemia or mixed dyslipidemia and from the FDA as an adjunct to diet and exercise to reduce low-density lipoprotein cholesterol, or LDL-C, in adults with hypercholesterolemia, adults and pediatric patients aged 12 years and older with heterozygous familial hypercholesterolemia, or HeFH, and pediatric patients aged 12 years and older with homozygous familial hypercholesterolemia. Leqvio has also been

approved in China and Japan, and as of the end of June 2026, Leqvio is registered in 109 countries worldwide and is commercially available in 89 countries.

Qfitlia (fitusiran) is being commercialized by our collaborator, Genzyme Corporation, a Sanofi Company, or Sanofi, and was approved by the FDA in March 2025 for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients 12 years of age and older with hemophilia A or B, with or without factor VIII or IX inhibitors (neutralizing antibodies), and by China’s National Medical Products Administration in December 2025, for routine prophylaxis to prevent or reduce the frequency of bleeding episodes in pediatric patients 12 years of age and older, and adults with severe hemophilia A with or without factor VIII inhibitors or severe hemophilia B with or without factor IX inhibitors. Qfitlia is the first and only therapeutic designed to lower antithrombin, a protein that inhibits blood clotting, with the goal of promoting thrombin generation to rebalance hemostasis and prevent bleeds.

In addition to our marketed products, we have multiple potential drivers of future growth, including additional transformative medicines currently in development for TTR and both other rare and prevalent diseases. We are advancing nucresiran, our next-generation investigational RNAi therapeutic in development for the treatment of ATTR amyloidosis. In November 2024, we announced positive results from the ongoing Phase 1 clinical trial of nucresiran in healthy volunteers. These results demonstrated that twice annual dosing of 300 mg of nucresiran resulted in mean reductions of serum TTR of greater than 90% from baseline at day 15 that were maintained over six months. In September 2025, we initiated the TRITON-PN Phase 3 clinical trial of nucresiran in patients with hATTR polyneuropathy, and in June 2025, we initiated the TRITON-CM Phase 3 clinical trial of nucresiran in patients with ATTR amyloidosis with cardiomyopathy. In April 2026, we announced that, due to enrollment in TRITON-CM proceeding faster than anticipated, we exercised a pre-specified protocol option to expand target enrollment by approximately 500 patients, or from 1,250 to approximately 1,750 patients in total. Given the current pace of enrollment and the anticipated accrual of endpoint events, we continue to expect to launch nucresiran in ATTR-CM by 2030, assuming positive data and regulatory approval.

We are developing zilebesiran, an investigational, subcutaneously administered RNAi therapeutic targeting angiotensinogen, for the treatment of hypertension. In 2023, we entered into a Collaboration and License Agreement, or the Roche Collaboration and License Agreement, with F. Hoffmann-La Roche Ltd. and Genentech, Inc. or, collectively, Roche, pursuant to which we established a worldwide, strategic collaboration for the joint development and commercialization of zilebesiran. In August 2025, we reported that our KARDIA-3 Phase 2 clinical trial, which was designed to evaluate the efficacy and safety of zilebesiran as an add-on therapy in adult patients with high cardiovascular risk and uncontrolled hypertension despite treatment with two to four standard of care antihypertensive medications, met the objective of informing the design, patient population, and dose for a global Phase 3 cardiovascular outcomes trial. In September 2025, we initiated a Phase 3 cardiovascular outcomes clinical trial, ZENITH (ZilebEsiraN CardIovascular OuTcome Study in Hypertension), which is designed to evaluate the potential of zilebesiran to reduce the risk of major adverse cardiovascular events in patients with uncontrolled hypertension on two or more antihypertensives, one being a diuretic.

We are advancing mivelsiran (formerly ALN-APP), an investigational RNAi therapeutic targeting amyloid precursor protein in development for the treatment of cerebral amyloid angiopathy, or CAA, and Alzheimer’s disease, or AD. In July 2025, we presented single- and multiple-dose data from the Phase 1 clinical trial of mivelsiran in patients with early-onset AD. These data demonstrated that single and multiple doses of mivelsiran were generally well tolerated and demonstrated robust, durable, dose-dependent reductions of soluble amyloid precursor protein beta, or sAPPβ, in cerebrospinal fluid. In July 2025, we presented an analysis of safety data from single and multiple doses of mivelsiran in the Phase 1 clinical trial showing no evidence of increased risk of amyloid-related imaging abnormality events. In July 2024, we initiated the cAPPricorn-1 Phase 2 clinical trial of mivelsiran in patients with CAA and in July 2026, we announced that we had completed enrollment in this trial. In July 2026, we announced the initiation of a Phase 2 clinical trial of mivelsiran in patients with Down syndrome-associated AD.

We are developing ALN-6400, a GalNAc-conjugated RNAi therapeutic that targets plasminogen, or PLG, for the treatment of a wide range of bleeding disorders. In preclinical studies, ALN-6400 demonstrated a greater than 90% reduction in circulating PLG in non-human primates with no evidence of increased risk of thrombosis. In early 2025, we shared data from the first cohort of participants in a Phase 1 clinical trial in healthy volunteers, demonstrating favorable impact on an ex-vivo hemostasis assay. In late 2025, we initiated a Phase 2 clinical trial of ALN-6400 in patients with Hereditary Hemorrhagic Telangiectasia, or HHT, and we plan to share additional data from the Phase 1 clinical trial as well as initial results in the Phase 2 clinical trial in HHT the second half of 2026. We also initiated a Phase 2 clinical trial of ALN-6400 in patients with von Willebrand Disease in the first half of 2026.

We are advancing ALN-HTT02, an investigational, intrathecally administered RNAi therapeu

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

We are a global commercial-stage biopharmaceutical company that discovers, develops, manufactures and commercializes novel therapeutics based on RNAi. Our commercial products and broad pipeline of investigational RNAi therapeutics are targeting a broad range of disease areas and indications.

As described in Part I, Item 1. “Business” of this Annual Report on Form 10-K, we currently have six products that have received marketing approval, including two products marketed by our collaborators, and multiple late-stage investigational programs advancing towards potential commercialization.

We achieved profitability for the first time in 2025, with full-year net product revenues of approximately $3.0 billion, driven primarily by strong growth in our TTR franchise. Nevertheless, we have incurred significant losses since inception and, as of December 31, 2025, we had an accumulated deficit of $6.70 billion. Historically, we generated losses primarily from costs associated with research and development activities; acquiring, filing and protecting our intellectual property rights; and selling, general and administrative activities. With the achievement of profitability in 2025, going forward we expect to be able to fund our operations primarily from product revenues, which we expect will be supplemented by collaboration revenue and royalty revenue from products commercialized by our collaborators.

We expect to continue investing significantly in research and development to advance our RNAi platform and clinical pipeline. These planned expenditures include costs associated with our activities as we (i) progress our late-stage programs, including the Phase 3 TRITON-PN and TRITON-CM clinical trials of nucresiran (our next generation TTR silencer) in patients with hATTR-PN and ATTR-CM, respectively, and the Phase 3 ZENITH cardiovascular outcomes trial of zilebesiran in patients with uncontrolled hypertension, all three of which we initiated in 2025; (ii) progress our early stage clinical pipeline, including CNS and metabolic programs; (iii) continue our efforts to deliver RNAi therapeutics to additional tissues and to treat new disease areas; and (iv) selectively pursue complementary modalities through business development.

Through these investments, we plan to expand our efforts to discover, develop and commercialize the next wave of RNAi therapeutics and aim to achieve the goals associated with our Alnylam 2030 strategy. These goals include expanding to 10 tissue types and more than 40 clinical programs, delivering at least two new transformative medicines beyond TTR with blockbuster potential, investing approximately 30% of our revenues in non-GAAP R&D (including select external innovation), achieving 25%+ total revenue compound annual growth rate, and delivering approximately 30% non-GAAP operating margin through year-end 2030.

As of December 31, 2025, we generate worldwide product revenues from our four commercialized products, AMVUTTRA, ONPATTRO, GIVLAARI and OXLUMO, primarily in the U.S. and Europe. Collaboration revenues, in particular from our collaborations with Roche, Regeneron and Novartis, have also represented a meaningful portion of our total revenues in recent years. We expect our sources of potential funding for the next several years to be derived primarily from sales of our commercialized products, with contributions from our existing collaborations, including royalties on sales of Leqvio by Novartis and on sales of Qfitlia by Sanofi, and any new strategic collaborations that we may enter in the future. However, we and our collaborators may not be able to successfully market and sell our existing commercialized products or any approved products in the future. Moreover, our ongoing development and regulatory efforts may not be successful, and we and our collaborators may not be able to commence sales of any other products in the future. We anticipate that our operating results will continue to fluctuate for the foreseeable future and, therefore, period-to-period comparisons should not be relied upon as predictive of the results in future periods.

Given the significant and growing contribution of AMVUTTRA to our total product revenues following regulatory approvals of AMVUTTRA for the treatment of ATTR-CM, our cost of goods sold, operating income and operating margin in 2025 were significantly impacted by the royalties we pay to Sanofi on global sales of AMVUTTRA under our TTR license agreements, and we expect this will continue in future years. Sanofi is eligible to receive tiered royalties on global annual net sales of AMVUTTRA across all indications in the following tiers: 15% of global annual net sales of $0 to $150.0 million; 17.5% of global annual net sales greater than $150.0 million to $300.0 million; 20% of global annual net sales greater than $300.0 million to $500.0 million; 25% of global annual net sales greater than $500.0 million to $1.50 billion; and 30% of global annual net sales in excess of $1.50 billion. There are no royalties owed on nucresiran, our next-generation investigational RNAi therapeutic, which is currently in development for the treatment of ATTR amyloidosis. Assuming successful development and regulatory approval, we believe that with its anticipated product profile, nucresiran has the potential to become a leading therapy for ATTR amyloidosis and to significantly improve our gross margins on product sales and our non-GAAP operating income margin.

Net product revenues increased during the year ended December 31, 2025, compared to the year ended December 31, 2024, primarily due to growth from AMVUTTRA revenues driven by increased patient demand, mainly in patients with ATTR-CM in the U.S., which was partially offset by a decreased number of patients on ONPATTRO, and due to growth from an increased number of patients on GIVLAARI and OXLUMO.

Please see Note 3, Net Product Revenues, to our consolidated financial statements included in Part II, Item 8, “Financial Statements and Supplementary Data” of this Annual Report on Form 10-K for balances and activity in each product revenue allowance and reserve category for the years ended December 31, 2025 and 2024.
