Net Product Revenues

• Net product revenues increased 76% and 83% during the three and twelve months ended December 31, 2021, respectively, compared to the same periods in 2020, primarily due to the continued, global expansion of ONPATTRO and GIVLAARI into additional major markets and increased patients on therapy, as well as sales generated from our third commercial product, OXLUMO, following regulatory approvals in the fourth quarter of 2020.

Net Revenues from Collaborations

• Net revenues from collaborations increased 18% and 38% during the three and twelve months ended December 31, 2021, respectively, compared to the same periods in 2020, primarily due to an increase in revenue from our collaboration agreements with Regeneron and Novartis, including the achievement of a $25 million regulatory milestone for Leqvio associated with FDA approval in Q4 2021.

Royalty Revenue

• Royalty revenue earned in 2021 represents initial Leqvio royalties from Novartis following Leqvio European Commission (EC) approval in December 2020. Following Leqvio FDA approval in December 2021, we anticipate an increase in royalties earned in 2022.

Research and Development (R&D) Expenses

• GAAP and Non-GAAP R&D expenses increased during the three and twelve months ended December, 31 2021, compared to the same periods in 2020, primarily due to increased expenses associated with activities related to the advancement of our HELIOS-B, APOLLO-B, KARDIA-1 and KARDIA-2 clinical programs. GAAP R&D expenses also increased due to upfront payments associated with the execution of certain collaboration agreements.

Selling, General & Administrative (SG&A) Expenses

• GAAP and Non-GAAP SG&A expenses increased during the three and twelve months ended December, 31 2021, compared to the same periods in 2020, primarily due to increased investment to support the growth of our three commercialized products as well as legal expenses associated with an ongoing Department of Justice investigation. On a GAAP basis, these increases were offset due to a change in an estimate of contingent liabilities related to our arbitration with Ionis Pharmaceuticals, Inc. in 2020.

Other Financial Highlights

Other (Expense) Income

• Total other expense increased during the three and twelve months ended December, 31 2021, compared to the same periods in 2020, primarily due to increased interest expense associated with the sale of future royalties and our credit facility, and increased expense associated with the mark-to-market adjustment related to the development derivative liability.

Cash and Investments

• Cash, cash equivalents and marketable securities were $2.44 billion as of December 31, 2021 compared to $1.87 billion at the end of 2020. The increase was primarily due to $500 million in proceeds from the sale of future royalties, $500 million from draw down on our credit facility and $233 million from the exercise of employee equity awards, offset by cash used in our operations to support overall growth.

A reconciliation of our GAAP to non-GAAP results for the current quarter is included in the tables of this press release.

2022 Financial Guidance1
Full year 2022 financial guidance consists of the following:
Combined net product revenues for ONPATTRO, GIVLAARI, OXLUMO and vutrisiran		$900 million – $1,000 million
Net revenues from collaborations and royalties		$175 million – $225 million
GAAP R&D and SG&A expenses		$1,630 million – $1,750 million
Non-GAAP R&D and SG&A expenses2		$1,400 million – $1,500 million
1 2022 FY Guidance is based upon January 31, 2022 FX rates of: 1 EUR = 1.12 USD; 1 GBP = 1.34 USD; 1 CHF = 1.08 USD; 1 CAD = 0.79 USD, 1 USD = 115 JPY 2 Primarily excludes $230-$250 million of stock-based compensation expense from estimated GAAP R&D and SG&A expenses.

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, unrealized (gains) losses on marketable equity securities, costs associated with our strategic financing collaboration, upfront payment on license and collaboration agreements, change in estimate of contingent liabilities and loss on contractual settlement. 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 unrealized (gains) 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. The Company has excluded the impact of the costs associated with our strategic financing collaboration, upfront payment on license and collaboration agreements, change in estimate of contingent liabilities and loss on contractual settlement because the Company believes these items are non-recurring transactions outside the ordinary course of the Company’s business.

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 was approved in the United States and Canada for the treatment of the polyneuropathy of hATTR amyloidosis in adults. 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) and should be administered via a healthcare professional. It is designed to target and silence TTR messenger RNA, thereby blocking the production of TTR protein before it is made. ONPATTRO blocks the production of TTR in the liver, reducing its accumulation in the body’s tissues in order to halt or slow down the progression of the polyneuropathy associated with the disease. For more information about ONPATTRO, including please see the full US Prescribing Information, visit ONPATTRO.com.

About GIVLAARI^® (givosiran)

GIVLAARI 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 aminolevulinic acid synthase 1 (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 is an RNAi therapeutic targeting hydroxyacid oxidase 1 (HAO1) for the treatment of primary hyperoxaluria type 1 (PH1) to lower urinary oxalate levels in pediatric and adult patients. HAO1 encodes glycolate oxidase (GO), an enzyme upstream of the disease-causing defect in PH1. OXLUMO works by degrading HAO1 messenger RNA and reducing the synthesis of GO, which inhibits hepatic production of oxalate – the toxic metabolite responsible for the clinical manifestations of PH1. 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. Injection site reactions (ISRs) were the most common drug-related adverse reaction. In the ILLUMINATE-B pediatric Phase 3 study, OXLUMO demonstrated an efficacy and safety profile consistent to that observed in ILLUMINATE-A. OXLUMO utilizes Alnylam’s Enhanced Stabilization Chemistry (ESC)-GalNAc conjugate technology designed to increase potency and durability. OXLUMO is administered via subcutaneous injection once monthly for three months, then once quarterly thereafter 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 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'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
