CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Biogen Inc. (Nasdaq: BIIB) today reported first quarter 2018 financial results, including:

• Total revenues of $3.1 billion, an 11% increase versus the prior year or a 15% increase excluding hemophilia revenues*.
  • Multiple sclerosis (MS) revenues were $2.1 billion, including approximately $77 million in royalties on the sales of OCREVUS®.
  • Revenue growth was principally driven by SPINRAZA®, which contributed $364 million in global revenues, biosimilars, which contributed $128 million, and Other Revenues of $164 million.
• GAAP net income and diluted earnings per share (EPS) attributable to Biogen Inc. of $1.2 billion and $5.54, respectively, compared to $748 million and $3.46 in the first quarter of 2017, respectively.
  • In the first quarter of last year GAAP net income and diluted EPS were negatively impacted by $243 million and $1.14, net of tax, respectively, related to the U.S. Patent and Trademark Office ruling in favor of Biogen in the Company's interference proceeding with Forward Pharma A/S.
• Non-GAAP net income and diluted EPS attributable to Biogen Inc. of $1.3 billion and $6.05, respectively, compared to $1.1 billion and $5.20 in the first quarter of 2017, respectively.

* In Q1 2017 Biogen completed the spin-off of its global hemophilia business. The 15% increase in total revenues excludes all hemophilia revenues in January 2017. Hemophilia revenues include ELOCTATE® and ALPROLIX® product revenues as well as royalty and contract manufacturing revenue related to Sobi.

• In the fourth quarter of 2017 GAAP net income and EPS were negatively impacted by $1.2 billion and $5.51, respectively, due to the transition toll tax and re-measurement of the Company’s net deferred tax assets related to the Tax Cuts and Jobs Act of 2017.

A reconciliation of GAAP to Non-GAAP quarterly financial results can be found in Table 3 at the end of this press release.

“We started 2018 well with our first quarter revenues growing 11% versus the prior year, or 15% excluding hemophilia revenues. This is in line with our expectations,” said Michel Vounatsos, Biogen’s Chief Executive Officer. “The fundamentals and resilience of our multiple sclerosis business remained strong, while we experienced anticipated seasonality at the beginning of the year. I believe there is significant opportunity for the future growth of SPINRAZA worldwide as we position Biogen for long-term leadership in spinal muscular atrophy.”

“As pioneers in neuroscience, we continued to advance and expand our portfolio of potential breakthrough treatments for areas of high unmet need. We have added a new Phase 2 asset in our emerging growth area of neuropsychiatry, and we meaningfully enhanced our collaboration with Ionis to develop a new pipeline of gene-based therapies for neurological diseases.”

• U.S. MS revenues in the first quarter of 2018 were negatively impacted by approximately $180 million due to the difference between the channel inventory level changes during the first quarter of 2018 and the fourth quarter of 2017 for TECFIDERA, AVONEX and PLEGRIDY.
• In the first quarter of 2017 TYSABRI revenues outside the U.S. benefitted by approximately $45 million due to reaching an agreement with the Price and Reimbursement Committee of the Italian National Medicines Agency (AIFA) related to TYSABRI sales in prior periods.
• In the first quarter of 2018 SPINRAZA revenues comprised $188 million in sales in the U.S. and $176 million in sales outside the U.S. The number of patients receiving SPINRAZA grew 16% in the U.S. and 56% outside the U.S. versus the fourth quarter of 2017. Outside the U.S., SPINRAZA revenues were primarily from Germany, Japan, Italy and France.
• Total revenues benefitted by approximately $54 million versus the prior year due to changes in foreign exchange rates, offset by hedging losses.

Business Development Updates

• In April 2018 Biogen and Ionis Pharmaceuticals Inc. (Ionis) announced a new ten-year exclusive collaboration agreement that leverages Biogen’s leadership in neuroscience research and drug development with Ionis’ leadership in antisense oligonucleotide (ASO) drug discovery to develop novel gene-based drug candidates for a broad range of neurological diseases. Under the terms of the collaboration, Biogen will make an upfront payment of $375 million and purchase $500 million of Ionis equity at a 25% cash premium, for a total expected payment of $1 billion. Biogen will have the option to license therapies arising out of this collaboration and will be responsible for their development and commercialization. Biogen may pay development milestones to Ionis of up to $125 million or $270 million, depending on the indication, and royalties on net sales. The transaction is subject to customary closing conditions, including the expiration of the applicable waiting period under the Hart Scott Rodino Antitrust Improvements Act of 1976 in the United States and is expected to close in the second quarter of 2018.
• In March 2018 Biogen announced an agreement to acquire from Pfizer Inc. BIIB104 (formerly known as PF-04958242), and the transaction closed today. BIIB104 is a first-in-class, Phase 2b ready AMPA receptor potentiator for cognitive impairment associated with schizophrenia (CIAS), representing the Company’s first program in neuropsychiatry. AMPA receptors mediate fast excitatory synaptic transmission in the central nervous system. BIIB104 has previously demonstrated an acceptable safety profile and treatment effect trends across key cognitive domains in Phase 1b clinical studies. The purchase included an upfront payment of $75 million with up to $515 million in additional development and commercialization milestone payments, as well as tiered royalties in the low to mid-teen percentages.

Recent Events

• This week, Biogen is presenting data from its portfolio of marketed treatments and clinical development programs for neurodegenerative diseases at the 70th annual meeting of the American Academy of Neurology (AAN) in Los Angeles, California. Platform and poster presentations are highlighting the benefits SPINRAZA provides for individuals with spinal muscular atrophy (SMA) across the age and disease spectrum, the Company’s MS therapies and non-therapeutic research collaborations designed to elevate the care of MS and the Company’s investigational therapies for Alzheimer’s disease, Parkinson’s disease and progressive supranuclear palsy.
• In April 2018 Biogen’s collaboration partner Applied Genetic Technologies Corporation announced that it has dosed the first patient in the Phase 1/2 clinical trial evaluating the safety and efficacy of an investigational AAV-based gene therapy for the treatment of x-linked retinitis pigmentosa.
• In April 2018 Biogen and Samsung Bioepis announced an agreement with AbbVie Inc. for the commercialization of IMRALDITM, a biosimilar referencing HUMIRA® (adalimumab). Under terms of the agreement, AbbVie will grant patent licenses for the use and sale of IMRALDI in Europe, on a country-by-country basis. The companies have agreed to dismiss all pending patent litigation. Biogen expects to launch IMRALDI in Europe in October 2018.
• In March 2018 Biogen initiated a Phase 1 study of BIIB095, a Nav 1.7 inhibitor for neuropathic pain.
• In March 2018 Biogen presented data from its portfolio of investigational therapies for people with neurodegenerative diseases at the Advances in Alzheimer’s and Parkinson’s Therapies (AAT-AD/PD) Focus Meeting in Torino, Italy. Data presented included an analysis from the Phase 1b PRIME study of aducanumab for early Alzheimer’s disease demonstrating a 69% reduction from baseline in amyloid plaque as observed on the Centiloid Conversion scale for the 10 mg/kg treatment group at 54 weeks (P<0.001 versus placebo).
• In March 2018 Biogen presented new data for SPINRAZA for the treatment of SMA at the Muscular Dystrophy Association (MDA) Clinical Conference in Arlington, Virginia. Data included new interim Phase 2 results from NURTURE, the ongoing open-label, single-arm study evaluating the efficacy and safety of SPINRAZA among pre-symptomatic infants with SMA. In NURTURE, all infants treated with SPINRAZA were alive, did not require permanent ventilation and showed improvement in motor function and motor milestone achievements as of July 5, 2017, compared to the disease’s natural history. Biogen also presented a case series demonstrating SPINRAZA’s effectiveness among teens and young adults.
• In March 2018 Biogen and AbbVie announced the voluntary worldwide withdrawal of ZINBRYTA for relapsing MS. The companies believe that characterizing the complex and evolving benefit/risk profile of ZINBRYTA will not be possible going forward given the limited number of patients being treated.
• In February 2018 the end of study results from CHERISH, the Phase 3 study evaluating SPINRAZA for the treatment of individuals with later-onset SMA, were published in The New England Journal of Medicine. Results from CHERISH demonstrated meaningful motor function and upper limb improvements in individuals with later-onset SMA rarely seen in the natural course of the disease, which is typically a continued decline in motor function over time.
• In February 2018 Biogen announced that in the Phase 2b dose-ranging ACTION 2 study in individuals with acute ischemic stroke (AIS), natalizumab did not demonstrate improvement in clinical outcomes compared to placebo. Both doses of natalizumab were generally well-tolerated and no new or important safety signals were observed. The results of the Phase 2b ACTION 2 study do not impact the benefit-risk profile of natalizumab in approved indications, including MS. Further development of natalizumab in AIS will not be pursued.

A Amortization of acquired intangible assets includes impairment and amortization charges related to the intangible asset associated with our U.S. and rest of world licenses to Forward Pharma A/S' (Forward Pharma) intellectual property, including Forward Pharma's intellectual property related to TECFIDERA. In exchange for these licenses, we paid Forward Pharma $1.25 billion in cash.

We have two intellectual property disputes with Forward Pharma, one in the U.S. and one in the European Union, concerning intellectual property related to TECFIDERA. In March 2017 the U.S. intellectual property dispute was decided in our favor. We evaluated the recoverability of the U.S. asset acquired from Forward Pharma and recorded an impairment charge in the first quarter of 2017 to adjust the carrying value of the acquired U.S. asset to fair value reflecting the impact of the developments in the U.S. legal dispute. In March 2018 the European Patent Office issued its decision revoking Forward Pharma’s European Patent No. 2 801 355. Based upon our assessment of these rulings, we continue to amortize the remaining net book value of the U.S. and rest of world intangible assets in our condensed consolidated statements of income utilizing an economic consumption model.

B Net distribution to noncontrolling interests for the three months ended December 31, 2017, reflects the after-tax $150.0 million upfront payment made to Neurimmune SubOne AG (Neurimmune) in exchange for a 15% reduction in royalty rates payable on potential commercial sales of aducanumab. This upfront payment is in relation to the amendment of terms of our collaboration agreement with Neurimmune.

C 2017 corporate strategy and restructuring charges are related to our efforts to create a leaner and simpler operating model.

D On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the 2017 Tax Act) was signed into law and has resulted in significant changes to the U.S. corporate income tax system. The 2017 Tax Act includes a federal statutory rate reduction from 35 percent to 21 percent, the elimination or reduction of certain domestic deductions and credits, the transition of U.S. international taxation from a worldwide tax system towards a territorial tax system, limitations on the deductibility of interest expense and executive compensation and base-erosion prevention measures on future non-U.S. earnings of U.S. entities, which has the effect of subjecting certain of our earnings of foreign subsidiaries to U.S. taxation. These changes became effective beginning in 2018.

The 2017 Tax Act also required a one-time mandatory deemed repatriation tax on accumulated foreign subsidiaries’ previously untaxed foreign earnings (the Transition Toll Tax). Changes in tax rates and tax laws are accounted for in the period of enactment. Therefore, during the three months ended December 31, 2017, we recorded a charge totaling $1,173.6 million related to our current estimate of the provisions of the 2017 Tax Act, including a $989.6 million expense under the Transition Toll Tax. The Transition Toll Tax must be paid over an eight-year period, starting in 2018, and will not accrue interest.

Use of Non-GAAP Financial MeasuresWe supplement our consolidated financial statements presented on a GAAP basis by providing additional measures which may be considered “Non-GAAP” financial measures under applicable SEC rules. We believe that the disclosure of these Non-GAAP financial measures provides additional insight into the ongoing economics of our business and reflects how we manage our business internally, set operational goals and forms the basis of our management incentive programs. These Non-GAAP financial measures are not in accordance with generally accepted accounting principles in the United States and should not be viewed in isolation or as a substitute for reported, or GAAP, net income attributable to Biogen Inc. and diluted earnings per share.

Our “Non-GAAP net income attributable to Biogen Inc.” and “Non-GAAP earnings per share - Diluted” financial measures exclude the following items from "GAAP net income attributable to Biogen Inc." and "GAAP earnings per share - Diluted":

1. Purchase accounting and merger-related adjustmentsWe exclude certain purchase accounting related items associated with the acquisition of businesses, assets and amounts in relation to the consolidation or deconsolidation of variable interest entities for which we are the primary beneficiary. These adjustments include, but are not limited to, charges for in-process research and development, the amortization of certain acquired intangible assets, and charges or credits from the fair value remeasurement of our contingent consideration obligations.

2. Hemophilia business separation costsWe have excluded costs that are directly associated with the set up and spin-off of our hemophilia business into an independent, publicly-traded company on February 1, 2017. These costs represent incremental third party costs attributable solely to hemophilia separation and set up activities.

3. Restructuring, business transformation and other cost saving initiativesWe exclude costs associated with the company’s execution of certain strategies and initiatives to streamline operations, achieve targeted cost reductions, rationalize manufacturing facilities or refocus R&D activities. These costs may include employee separation costs, retention bonuses, facility closing and exit costs, asset impairment charges or additional depreciation when the expected useful life of certain assets have been shortened due to changes in anticipated usage, and other costs or credits that management believes do not have a direct correlation to our on-going or future business operations.

4. Loss (gain) on equity security investmentsEffective January 2018, we exclude unrealized and realized gains and losses and discounts or premiums on our equity security investments as we do not believe that these components of income or expense have a direct correlation to our on-going or future business operations.
