Alnylam Pharmaceuticals Reports Fourth Quarter and Full Year 2014 Financial Results and Highlights Recent Period Progress

– Introduced Pipeline Growth Strategy for RNAi Therapeutics in Three Strategic Therapeutic Areas, or “STArs,” and Launched “Alnylam 2020” Guidance for Advancement and Commercialization of RNAi Therapeutics –

– Presented Positive Data from Multiple Clinical Programs, Including Initial Evidence of Potential Disease Modifying Effects with Patisiran and ALN-AT3 –

– Advanced Revusiran into ENDEAVOUR Phase 3 Trial and Added Three New Programs into Clinical Stages –

– Maintained Strong Balance Sheet with $882 Million in Cash and Expects to End 2015 with Greater than $1.2 Billion in Cash –

CAMBRIDGE, Mass.--(BUSINESS WIRE)--February 12, 2015--Alnylam Pharmaceuticals, Inc. (Nasdaq: ALNY), a leading RNAi therapeutics company, today reported its consolidated financial results for the fourth quarter and full year 2014, and highlighted recent progress in advancing its pipeline.

“Alnylam made excellent progress in the fourth quarter of 2014 and the recent period, as we continued advancing RNAi therapeutics in clinical studies. Amongst other highlights, we reported clinical data from our patisiran and ALN-AT3 programs showing what we believe to be early evidence for the translation of RNAi-mediated knockdown into potential clinical benefit for patients. We also executed on our pipeline goals, with strong enrollment in our patisiran APOLLO Phase 3 study and advancement of revusiran into our ENDEAVOUR Phase 3 trial. In addition, we filed three Clinical Trial Applications for ALN-PCSsc, ALN-CC5, and ALN-AS1, and have initiated Phase 1 studies for two of those programs,” said John Maraganore, Ph.D., Chief Executive Officer of Alnylam. “Alnylam also introduced its pipeline growth strategy and new guidance. Specifically, Alnylam intends to advance its pipeline in three Strategic Therapeutic Areas, or ‘STArs’ – Genetic Medicines, Cardio-Metabolic Disease, and Hepatic Infectious Disease – where we believe there are significant opportunities for RNAi therapeutics as high impact medicines. Further, with ‘Alnylam 2020’ we have launched new guidance that marks our expected transition from a late-stage clinical development company to a multi-product commercial-stage company with a sustainable development pipeline – a profile that we believe has rarely been achieved in the biopharmaceutical industry.”

“Alnylam continues to maintain a very strong balance sheet, ending 2014 with approximately $882 million in cash,” said Michael Mason, Vice President, Finance & Treasurer. “We also further strengthened our balance sheet earlier this year with a public offering and concurrent private placements from Genzyme that resulted in net proceeds of approximately $567 million. This financing results in a balance sheet that allows us to invest in a broad pipeline of RNAi therapeutics across all three STArs, which we believe should enable us to achieve our ‘Alnylam 2020’ guidance. As for financial guidance this year, we expect to end 2015 with greater than $1.2 billion in cash.”

Financials

Cash, Cash Equivalents and Total Marketable Securities

At December 31, 2014, Alnylam had cash, cash equivalents and total marketable securities of $881.9 million, as compared to $350.5 million at December 31, 2013.

In January 2015, Alnylam sold an aggregate of 5,447,368 shares of its common stock through an underwritten public offering at a price to the public of $95.00 per share. As a result of the offering, Alnylam received aggregate net proceeds of approximately $496.4 million.

In January 2015, in connection with our public offering described above, Genzyme exercised its right under the investor agreement between Alnylam and Genzyme, to purchase, in concurrent private placements, 744,566 shares of common stock, at the public offering price of $95.00 per share, resulting in proceeds to Alnylam of approximately $70.7 million. The exercise of this right allowed Genzyme to maintain its current ownership level of Alnylam common stock of approximately 12%.

Non-GAAP Net Loss

The non-GAAP net loss for the year ended December 31, 2014 was $139.6 million, or $1.88 per share on both a basic and diluted basis as compared to a non-GAAP net loss of $89.2 million, or $1.45 per share on both a basic and diluted basis for the prior year. The non-GAAP net loss for the year ended December 31, 2014 excludes the $220.8 million charge to in-process research and development expense in connection with the purchase of the Sirna RNAi assets from Merck, described below.

GAAP Net Loss

The net loss according to GAAP for the fourth quarter of 2014 was $21.4 million, or $0.28 per share on both a basic and diluted basis (including $13.4 million, or $0.17 per share of non-cash stock-based compensation expense), as compared to a net loss of $32.4 million, or $0.51 per share on both a basic and diluted basis (including $5.4 million, or $0.09 per share of non-cash stock-based compensation expense), for the same period in the previous year. For the year ended December 31, 2014, the net loss was $360.4 million, or $4.85 per share (including $33.1 million, or $0.45 per share of non-cash stock-based compensation expense), as compared to a net loss of $89.2 million, or $1.45 per share (including $20.7 million, or $0.34 per share of non-cash stock-based compensation expense), for the same period in the previous year. The increase in net loss for the year ended December 31, 2014 compared to the prior year resulted primarily from a $220.8 million charge to in-process research and development expense in connection with the purchase of the Sirna RNAi assets from Merck, described below.

Revenues

Revenues were $24.0 million for the fourth quarter of 2014, as compared to $10.8 million for the same period last year. Revenues for the fourth quarter of 2014 included $8.8 million in revenues from the company’s collaboration with Monsanto, $6.9 million of revenues related to the company’s collaboration with The Medicines Company, $5.5 million of revenues from the company’s alliance with Takeda Pharmaceuticals Company Limited, and $2.8 million of revenues from research reagent licenses and other sources. Revenues were $50.6 million for the year ended December 31, 2014, as compared to $47.2 million for the prior year. Revenues for the year ended December 31, 2014 included $22.0 million of revenues related to the company’s collaboration with Takeda, $15.0 million of revenues related to the company’s collaboration with Monsanto, $10.8 million of revenues related to the company’s collaboration with The Medicines Company, and $2.8 million of revenues from research reagent licenses and other sources.

Research and Development Expenses

Research and development (R&D) expenses were $55.5 million in the fourth quarter of 2014, which included $8.2 million of non-cash stock-based compensation, as compared to $32.1 million in the fourth quarter of 2013, which included $3.3 million of non-cash stock-based compensation. R&D expenses were $190.2 million for the year ended December 31, 2014, which included $18.2 million of non-cash stock-based compensation, as compared to $113.0 million for the prior year, which included $14.4 million of non-cash stock-based compensation. The increase in R&D expenses for the quarter and year ended December 31, 2014 as compared to the prior year periods was due primarily to additional expenses associated with the significant advancement of certain of the company’s clinical and pre-clinical programs. The company expects that R&D expenses will increase significantly in 2015 as it continues to advance and expand its pipeline across its three STArs.

In-Process Research and Development Expense

In 2014, the company incurred a $220.8 million charge to in-process research and development expense in connection with the purchase of the Sirna RNAi assets from Merck. In future periods, there will be no additional charges recorded to in-process research and development related to this purchase of the Sirna RNAi assets from Merck.

General and Administrative Expenses

General and administrative (G&A) expenses were $14.2 million in the fourth quarter of 2014, which included $5.2 million of non-cash stock-based compensation, as compared to $8.3 million in the fourth quarter of 2013, which included $2.1 million of non-cash stock-based compensation. G&A expenses were $44.5 million for the year ended December 31, 2014, which included $14.8 million of non-cash stock-based compensation, as compared to $27.2 million in 2013, which included $6.3 million of non-cash stock-based compensation. G&A expenses for the quarter and year ended December 31, 2014 as compared to the prior year periods increased due primarily to an increase in non-cash stock-based compensation expenses. In addition, consulting and professional services increased during the year ended December 31, 2014 as compared to the prior year related to general business activities and certain professional services. The company expects that G&A expenses will increase slightly in 2015.

Benefit from (Provision for) Income Taxes

The company had a benefit from income taxes of $22.1 million for the fourth quarter of 2014 as compared to a provision for income taxes of $3.0 million for the fourth quarter of 2013. The company’s benefit from income taxes was $40.2 million for the year ended December 31, 2014, as compared to $2.7 million for the prior year. The increase during the quarter and year ended December 31, 2014 as compared to the prior year periods was due primarily to the corresponding income tax expense associated with the increase in the value of our investment in Regulus, as well as the difference between the value of stock and the cash proceeds received from Genzyme for the issuance of our common stock. The corresponding income tax expense has been recorded in other comprehensive income and additional paid-in capital, respectively.

Investment in Regulus Therapeutics

The company accounts for its investment in Regulus at fair value by adjusting the value to reflect fluctuations in Regulus’ stock price each reporting period. At December 31, 2014, the fair market value of the company’s investment in Regulus was $94.6 million as compared to $45.5 million at December 31, 2013.

2015 Financial Guidance

Alnylam expects that its cash, cash equivalents, and total marketable securities balance will be greater than $1.2 billion at December 31, 2015.

About RNAi
RNAi (RNA interference) is a revolution in biology, representing a breakthrough in understanding how genes are turned on and off in cells, and a completely new approach to drug discovery and development. Its discovery has been heralded as “a major scientific breakthrough that happens once every decade or so,” and represents one of the most promising and rapidly advancing frontiers in biology and drug discovery today which was awarded the 2006 Nobel Prize for Physiology or Medicine. RNAi is a natural process of gene silencing that occurs in organisms ranging from plants to mammals. By harnessing the natural biological process of RNAi occurring in our cells, the creation of a major new class of medicines, known as RNAi therapeutics, is on the horizon. Small interfering RNA (siRNA), the molecules that mediate RNAi and comprise Alnylam's RNAi therapeutic platform, target the cause of diseases by potently silencing specific mRNAs, thereby preventing disease-causing proteins from being made. RNAi therapeutics have the potential to treat disease and help patients in a fundamentally new way.

About GalNAc Conjugates and Enhanced Stabilization Chemistry (ESC) GalNAc Conjugates
GalNAc-siRNA conjugates are a proprietary Alnylam delivery platform and are designed to achieve targeted delivery of RNAi therapeutics to hepatocytes through uptake by the asialoglycoprotein receptor. Alnylam’s Enhanced Stabilization Chemistry (ESC) GalNAc-conjugate technology enables subcutaneous dosing with increased potency, durability, and a wide therapeutic index, and is being employed in several of Alnylam’s genetic medicine programs, including programs in clinical development.

About LNP Technology
Alnylam has licenses to Tekmira LNP intellectual property for use in RNAi therapeutic products using LNP technology.

Use of Non-GAAP Financial Measures

The company supplements its condensed consolidated financial statements presented on a GAAP basis by providing additional measures that are considered “non-GAAP” financial measures under applicable SEC rules. These non-GAAP financial measures are not prepared in accordance with generally accepted accounting principles in the United States (GAAP) and should not be viewed in isolation or as a substitute for GAAP net loss and basic and diluted net loss per common share.

The company evaluates items on an individual basis, and considers both the quantitative and qualitative aspects of the item, including (i) its size and nature, (ii) whether or not it relates to the company’s ongoing business operations, and (iii) whether or not the company expects it to occur as part of its normal business on a regular basis. In the year ended December 31, 2014, the company’s Non-GAAP net loss and Non-GAAP net loss per common share – basic and diluted financial measures excludes the in-process research and development expense of $220.8 million related to the purchase of the Sirna RNAi assets from Merck. The company believes that the exclusion of this item provides management and investors with supplemental measures of performance that better reflect the underlying economics of the company’s business. In addition, the company believes the exclusion of this item is important in comparing current results with prior period results and understanding projected operating performance. Management uses these non-GAAP financial measures to establish budgets and operational goals and to manage the company’s business.

This selected financial information should be read in conjunction with the consolidated financial statements and notes thereto included in Alnylam’s Annual Report on Form 10-K which includes the audited financial statements for the year ended December 31, 2013.
