Financial Results for the Quarter Ended March 31, 2024 Three Months Ended March 31, (In thousands, except per share amounts) 2024 2023 Net product revenues $ 365,163 $ 276,328 Net revenue from collaborations $ 118,548 $ 36,462 Royalty revenue $ 10,622 $ 6,500 GAAP Operating loss $ (43,435 ) $ (149,807 ) Non-GAAP Operating gain (loss) $ 1,912 $ (109,860 ) GAAP Net loss $ (65,935 ) $ (174,101 ) Non-GAAP Net loss $ (20,666 ) $ (131,887 ) GAAP Net loss per common share - basic and diluted $ (0.52 ) $ (1.40 ) Non-GAAP Net loss per common share - basic and diluted $ (0.16 ) $ (1.06 ) For an explanation of our use of non-GAAP financial measures refer to the “Use of Non-GAAP Financial Measures” section later in this press release and for a reconciliation of each non-GAAP financial measure to the most comparable GAAP measures, see the table at the end of this press release. Net Product Revenues Three Months Ended March 31, Year over Year % Growth (In thousands, except percentages) 2024 2023 As Reported At CER* ONPATTRO net product revenues $ 69,217 $ 102,493 (32)% (33)% AMVUTTRA net product revenues 195,241 101,768 92% 93% Total TTR net product revenues 264,458 204,261 29% 30% GIVLAARI net product revenues 58,056 47,906 21% 21% OXLUMO net product revenues 42,649 24,161 77% 75% Total Rare net product revenues 100,705 72,067 40% 39% Total net product revenues $ 365,163 $ 276,328 32% 32% * CER = Constant Exchange Rate, representing growth calculated as if the exchange rates had remained unchanged from those used in the first quarter 2023. CER is a Non-GAAP measure. Total net product revenues increased 32% at both actual currency and CER during the three months ended March 31, 2024, as compared to the same period in 2023, due to strong growth from AMVUTTRA driven by increased patient demand, as well as increased patients on our GIVLAARI and OXLUMO therapies. Net Revenues from Collaborations Net revenues from collaborations increased 225% during the three months ended March 31, 2024, as compared to the same period in 2023, primarily due to revenue recognized under our collaboration and license agreement with Roche, including $65 million of milestone revenue associated with dosing the first patient in the zilebesiran KARDIA-3 clinical trial, and an increase in revenue recognized under our collaboration agreement with Regeneron as a result of an increase in activities under our research services arrangement and licensed programs. Operating Expenses Three Months Ended March 31, (In thousands, except percentages) 2024 2023 Cost of goods sold $ 54,613 $ 41,432 Cost of goods sold as a percentage of net product revenues 15.0 % 15.0 % Cost of collaborations and royalties $ 11,363 $ 13,437 GAAP research and development expenses $ 260,995 $ 230,569 Non-GAAP research and development expenses $ 241,780 $ 214,337 GAAP selling, general and administrative expenses $ 210,797 $ 183,659 Non-GAAP selling, general and administrative expenses $ 184,665 $ 159,944 Cost of Goods Sold Cost of goods sold as a percentage of net product revenues was consistent during the three months ended March 31, 2024, as compared to the same period in 2023, primarily due to increased royalties related to higher AMVUTTRA sales volume, partially offset by one-time favorability attributed to reduced ONPATTRO manufacturing cancellation fees. Research & Development (R&D) Expenses GAAP and non-GAAP R&D expenses increased during the three months ended March 31, 2024, as compared to the same period in 2023, primarily due to increased development expenses associated with zilebesiran in the KARDIA-2 and KARDIA-3 clinical studies, increased expenses associated with our HELIOS-B study leading up to the topline data readout in late June or early July 2024, increased costs associated with our preclinical activities, specifically our CNS programs, and increased headcount and infrastructure expenses to support our R&D pipeline. Selling, General & Administrative (SG&A) Expenses GAAP and non-GAAP SG&A expenses increased during the three months ended March 31, 2024, as compared to the same period in 2023, primarily due to increased marketing investment associated with promotion of our TTR therapies and increased headcount and other investments supporting our strategic growth. Other Financial Highlights Cash, cash equivalents and marketable securities were $2.37 billion as of March 31, 2024 compared to $2.44 billion as of December 31, 2023 with the decrease primarily due our operating loss in the first quarter 2024. A reconciliation of our GAAP to non-GAAP results for the quarter is included in the tables at the end of this press release. 2024 Financial Guidance Full year 2024 financial guidance is reiterated as follows: Combined net product revenues for ONPATTRO, AMVUTTRA, GIVLAARI and OXLUMO1 $1,400 million - $1,500 million Net Product Revenue Growth vs. 2023 at reported FX rates1 13% to 21% Net Product Revenue Growth vs. 2023 at CER* 13% to 21% Net revenues from collaborations and royalties $325 million - $425 million GAAP R&D and SG&A expenses $1,900 million - $2,050 million Non-GAAP R&D and SG&A expenses2 $1,675 million - $1,775 million 1 Uses January 31, 2024 FX rates including: 1 EUR = 1.08 USD and 1 USD = 147 JPY 2 Primarily excludes $225 - $275 million of stock-based compensation expense from estimated GAAP R&D and SG&A expenses *CER = Constant Exchange Rate, representing growth calculated as if the exchange rates had remained unchanged from those used in the twelve months ended December 31, 2023. CER is a Non-GAAP measure. Use of Non-GAAP Financial Measures This press release contains non-GAAP financial measures, including expenses adjusted to exclude certain non-cash expenses and non-recurring gains outside the ordinary course of the Company’s business. These measures are not in accordance with, or an alternative to, GAAP, and may be different from non-GAAP financial measures used by other companies. The items included in GAAP presentations but excluded for purposes of determining non-GAAP financial measures for the periods presented in this press release are stock-based compensation expenses and realized and unrealized losses on marketable equity securities. The Company has excluded the impact of stock-based compensation expense, which may fluctuate from period to period based on factors including the variability associated with performance-based grants for stock options and restricted stock units and changes in the Company’s stock price, which impacts the fair value of these awards. The Company has excluded the impact of the realized and unrealized losses on marketable equity securities because the Company does not believe these adjustments accurately reflect the performance of the Company’s ongoing operations for the period in which such gains or losses are reported, as their sole purpose is to adjust amounts on the balance sheet. Percentage changes in revenue growth at CER are presented excluding the impact of changes in foreign currency exchange rates for investors to understand the underlying business performance. The current period’s foreign currency revenue values are converted into U.S. dollars using the average exchange rates from the prior period. The Company believes the presentation of non-GAAP financial measures provides useful information to management and investors regarding the Company’s financial condition and results of operations. When GAAP financial measures are viewed in conjunction with non-GAAP financial measures, investors are provided with a more meaningful understanding of the Company’s ongoing operating performance and are better able to compare the Company’s performance between periods. In addition, these non-GAAP financial measures are among those indicators the Company uses as a basis for evaluating performance, allocating resources and planning and forecasting future periods. Non-GAAP financial measures are not intended to be considered in isolation or as a substitute for GAAP financial measures. A reconciliation between GAAP and non-GAAP measures is provided later in this press release.

About ONPATTRO® (patisiran) ONPATTRO is an RNAi therapeutic that is approved in the United States and Canada for the treatment of adults with hATTR amyloidosis with polyneuropathy. ONPATTRO is also approved in the European Union, Switzerland and Brazil for the treatment of hATTR amyloidosis in adults with Stage 1 or Stage 2 polyneuropathy, and in Japan for the treatment of hATTR amyloidosis with polyneuropathy. ONPATTRO is an intravenously administered RNAi therapeutic targeting transthyretin (TTR). It is designed to target and silence TTR messenger RNA, thereby reducing the production of TTR protein before it is made. Reducing the pathogenic protein leads to a reduction in amyloid deposits in tissues. For more information about ONPATTRO, including full Prescribing Information, visit ONPATTRO.com. About AMVUTTRA® (vutrisiran) AMVUTTRA® (vutrisiran) is an RNAi therapeutic approved in the United States for the treatment of adults with hATTR amyloidosis with polyneuropathy. It is a double-stranded small interfering RNA (siRNA) that targets mutant and wild-type transthyretin (TTR) messenger RNA (mRNA). Using Alnylam’s Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate delivery platform, AMVUTTRA is designed for increased potency and high metabolic stability to allow for subcutaneous injection once every three months (quarterly). Results from the pivotal HELIOS-A Phase 3 study demonstrate AMVUTTRA rapidly reduces serum TTR levels, has the potential to reverse neuropathy impairment relative to baseline and improves other key measures of disease burden relative to external placebo in patients with the polyneuropathy of hATTR amyloidosis. For more information about AMVUTTRA, including the full U.S. Prescribing Information, visit AMVUTTRA.com. About GIVLAARI® (givosiran) GIVLAARI (givosiran) is an RNAi therapeutic targeting aminolevulinic acid synthase 1 (ALAS1) approved in the United States and Brazil for the treatment of adults with acute hepatic porphyria (AHP). GIVLAARI is also approved in the European Union for the treatment of AHP in adults and adolescents aged 12 years and older. In the pivotal study, givosiran was shown to significantly reduce the rate of porphyria attacks that required hospitalizations, urgent healthcare visits or intravenous hemin administration at home compared to placebo. GIVLAARI is Alnylam’s first commercially available therapeutic based on its Enhanced Stabilization Chemistry ESC-GalNAc conjugate technology to increase potency and durability. GIVLAARI is administered via subcutaneous injection once monthly at a dose based on actual body weight and should be administered by a healthcare professional. GIVLAARI works by specifically reducing elevated levels of ALAS1 messenger RNA (mRNA), leading to reduction of toxins associated with attacks and other disease manifestations of AHP. For more information about GIVLAARI, including the full U.S. Prescribing Information, visit GIVLAARI.com. About OXLUMO® (lumasiran) OXLUMO (lumasiran) is an RNAi therapeutic targeting hydroxyacid oxidase 1 (HAO1). HAO1 encodes glycolate oxidase (GO). Thus, by silencing HAO1 and depleting the GO enzyme, OXLUMO inhibits production of oxalate – the metabolite that directly contributes to the pathophysiology of PH1. OXLUMO utilizes Alnylam’s Enhanced Stabilization Chemistry (ESC)-GalNAc-conjugate technology, which enables subcutaneous dosing with increased potency and durability and a wide therapeutic index. OXLUMO has received regulatory approvals from the U.S. Food and Drug Administration (FDA) for the treatment of primary hyperoxaluria type 1 (PH1) to lower urinary and plasma oxalate levels in pediatric and adult patients and from the European Medicines Agency (EMA) for the treatment of PH1 in all age groups. In the pivotal ILLUMINATE-A study, OXLUMO was shown to significantly reduce levels of urinary oxalate relative to placebo, with the majority of patients reaching normal or near-normal levels. In the ILLUMINATE-B pediatric Phase 3 study, OXLUMO demonstrated an efficacy and safety pro to that observed in ILLUMINATE-A. In the ILLUMINATE-C study, OXLUMO resulted in substantial reductions in plasma oxalate in patients with advanced PH1. Across all three studies, injection site reactions (ISRs) were the most common drug-related adverse reaction. OXLUMO is administered via subcutaneous injection once monthly for three months, then once quarterly beginning one month after the last loading dose at a dose based on actual body weight. For patients who weigh less than 10 kg, ongoing dosing remains monthly. OXLUMO should be administered by a healthcare professional. For more information about OXLUMO, including the full U.S. Prescribing Information, visit OXLUMO.com. About LNP Technology Alnylam has licenses to Arbutus Biopharma lipid nanoparticle (LNP) intellectual property for use in RNAi therapeutic products using LNP technology. About RNAi RNAi (RNA interference) is a natural cellular process of gene silencing that represents one of the most promising and rapidly advancing frontiers in biology and drug development today. Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and was recognized with the award of the 2006 Nobel Prize for Physiology or Medicine. By harnessing the natural biological process of RNAi occurring in our cells, a new class of medicines known as RNAi therapeutics is now a reality. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam Alnylam’s RNAi therapeutic platform, function upstream of today’s medicines by potently silencing messenger RNA (mRNA) – the genetic precursors – that encode for disease-causing or disease pathway proteins, thus preventing them from being made. This is a revolutionary approach with the potential to transform the care of patients with genetic and other diseases. About Alnylam Pharmaceuticals Alnylam Pharmaceuticals (Nasdaq: ALNY) has led the translation of RNA interference (RNAi) into a whole new class of innovative medicines with the potential to transform the lives of people afflicted with rare and prevalent diseases with unmet need. Based on Nobel Prize-winning science, RNAi therapeutics represent a powerful, clinically validated approach yielding transformative medicines. Since its founding in 2002, Alnylam has led the RNAi Revolution and continues to deliver on a bold vision to turn scientific possibility into reality.
