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

“Biogen performed well against our strategic and operational priorities in the most recent quarter,” said Michel Vounatsos, Biogen’s chief executive officer. “Reported revenues grew at a double-digit rate boosted by strong gains from SPINRAZA, our biosimilars business, and OCREVUS royalties versus a year ago. Net income and earnings per share both increased at double-digit rates supported by a lower tax rate and a lower share count. Our core MS business was relatively resilient during the quarter. For SPINRAZA, in the U.S. we saw increased new patient demand among adults. Outside of the U.S., SPINRAZA revenues benefitted from strong patient uptake across a number of geographies, as well as broadening approvals and solid reimbursement patterns.”
“Biogen continued to advance our pipeline beyond our industry leading portfolios in MS and Alzheimer’s,” Mr. Vounatsos continued. “In the third quarter, we made notable progress in stroke, progressive supranuclear palsy, and ALS. As ever, we remain focused on allocating our capital properly and efficiently with the goal of maximizing returns on behalf of our shareholders over the long-term.”

• | At CTAD, Biogen’s collaborator Eisai Co., Ltd. (Eisai) will also present clinical and biomarker updates from the Phase 2 study of BAN2401, an anti-amyloid beta antibody, along with safety and efficacy data for elenbecestat (development code: E2609), an investigational oral beta-amyloid cleaving enzyme (BACE) inhibitor, from the Phase 2 study in MCI to moderate AD. The BAN2401 presentation will be webcast live on Eisai’s website on Thursday, October 25, 8:30-9:30 a.m. ET / 2:30-3:30 p.m. CEST.

• | Today Biogen and UCB announced top-line results from a Phase 2b study evaluating the safety and efficacy of dapirolizumab pegol (DZP), an anti-CD40L pegylated Fab, in adults with moderately-to-severely active systemic lupus erythematosus (SLE) despite receiving standard-of-care treatment such as corticosteroids, anti-malarials and non-biological immunosuppressants. The primary endpoint of the study to demonstrate a dose response at 24 weeks on the British Isles Lupus Assessment Group (BILAG)-based Composite Lupus Assessment (BICLA) was not met (p=0.06). The study did demonstrate consistent and potentially meaningful improvements for the majority of clinical endpoints in patients treated with DZP compared with placebo. In addition, biomarker data demonstrated evidence of proof of biology. DZP was well tolerated and demonstrated an acceptable safety profile. Biogen and UCB continue to further evaluate these data while assessing potential next steps. The companies expect to present this data at a future scientific forum.

• | In October 2018 Biogen and Samsung Bioepis Co. Ltd. announced the European launch of IMRALDI, an adalimumab biosimilar referencing Humira. IMRALDI is approved in Europe for the treatment of rheumatoid arthritis, juvenile idiopathic arthritis, axial spondyloarthritis, psoriatic arthritis, psoriasis, paediatric plaque psoriasis, adult and adolescent hidradenitis suppurativa, Crohn’s disease, paediatric Crohn’s disease, ulcerative colitis, and uveitis.

• | In October 2018 Biogen presented data in more than 70 oral and poster presentations at the 34 th Congress of the European Committee for Treatment and Research in MS (ECTRIMS) in Berlin, Germany. Key updates included clinical data and real-world evidence that further support the long-term efficacy and well-characterized safety of Biogen’s leading MS therapies, including data supporting the use of TECFIDERA and TYSABRI early within the disease course. Additional data highlighted the potential utility of serum neurofilament light (sNfL) as a biomarker of MS disease activity and updates on Biogen’s efforts to improve monitoring of cognition and other key MS outcomes through MS PATHS (Multiple Sclerosis Partners Advancing Technology and Health Solutions).

• | In October 2018 Biogen presented new interim results from NURTURE, an ongoing open-label, single-arm efficacy and safety study of SPINRAZA in 25 presymptomatic infants with spinal muscular atrophy (SMA) at the Annual Congress of the World Muscle Society (WMS) held in Mendoza, Argentina. As of May 2018 all NURTURE study participants were alive and none required permanent ventilation, in contrast to the natural history of SMA. In addition, 100% of study participants achieved the motor milestone of sitting independently, 88% were able to walk with assistance, and 77% were able to walk independently. All NURTURE study participants were older than 15 months at the time of the analysis.

• | In October 2018 Biogen presented data from its movement disorders portfolio at the International Congress of Parkinson’s Disease and Movement Disorders (MDS) in Hong Kong. Data presented included safety data from the Phase 1 long-term extension study of BIIB092, an anti-tau antibody, in progressive supranuclear palsy (PSP), baseline demographics from the BIIB092 Phase 2 PASSPORT study in PSP, and the design of the BIIB054 Phase 2 SPARK study in Parkinson’s disease.

• | In September 2018 Biogen received results from the Phase 2b study of vixotrigine (BIIB074) in painful lumbosacral radiculopathy (PLSR). The study did not meet its primary or secondary efficacy endpoints, and the Company will discontinue development in this indication. The safety data were consistent with the profile reported in previous studies. In addition, the Company has delayed the initiation of the Phase 3 studies of vixotrigine in trigeminal neuralgia as it awaits the outcome of ongoing interactions with the U.S. Food and Drug Administration regarding the design of the Phase 3 studies, a more detailed review of the Phase 2b PLSR data, and insights from the ongoing Phase 2 study in small fiber neuropathy.

• | In September 2018 Biogen completed enrollment in the Phase 2b AFFINITY study, evaluating opicinumab as an add-on therapy in MS patients who are adequately controlled on their anti-inflammatory disease-modifying therapy (DMT), versus the DMT alone. Opicinumab is a first-in-class human monoclonal antibody directed against LINGO-1 and is being evaluated to determine its potential for improving pre-existing disability in relapsing MS patients through remyelination.

• | In September 2018 Biogen enrolled the first patient in the Phase 2b study evaluating BG00011 (STX-100) in idiopathic pulmonary fibrosis.

• | In September 2018 Biogen completed enrollment in the Phase 2 study of BIIB092 in PSP.

• | In September 2018 Biogen enrolled the first patient in the Phase 1 study evaluating BIIB078 (IONIS-C9 Rx), an antisense oligonucleotide drug candidate, in adults with C9ORF72-associated amyotrophic lateral sclerosis.

• | In August 2018 Biogen enrolled the first patient in the global Phase 3 CHARM study, designed to evaluate BIIB093 (intravenous (IV) glibenclamide) for the prevention and treatment of severe cerebral edema in large hemispheric infarction, one of the most severe types of ischemic stroke.

• | In July 2018 Eisai presented detailed results from the Phase 2 study (Study 201) of BAN2401, as well as detailed results from the Phase 2 study (Study 202) of elenbecestat, at the 2018 Alzheimer’s Association International Conference (AAIC) in Chicago.

A Amortization of acquired intangible assets for the three and nine months ended September 30, 2018, includes the impact of impairment charges related to certain in-process research and development (IPR&D) assets associated with our vixotrigine (BIIB074) program totaling $189.3 million.
During the third quarter of 2018 we completed a Phase 2b study for vixotrigine in painful lumbosacral radiculopathy (PLSR). The study did not meet its primary or secondary efficacy endpoints and we will discontinue development in PLSR. As a result, we recognized an impairment charge of approximately $60.0 million during the third quarter of 2018 to reduce the fair value of the IPR&D intangible asset to zero.
In addition, we have delayed the initiation of the Phase 3 studies of vixotrigine in trigeminal neuralgia (TGN) as we await the outcome of ongoing interactions with the U.S. Food and Drug Administration regarding the design of the Phase 3 studies, a more detailed review of the data from the Phase 2b study of vixotrigine in PLSR and insights from the Phase 2 study of vixotrigine in small fiber neuropathy. We have reassessed the fair value of the TGN program using reduced expected lifetime revenues, higher expected clinical development costs and a lower cumulative probability of success. As a result, we recognized an impairment charge of $129.3 million during the third quarter of 2018 to reduce the fair value of the TGN IPR&D intangible asset to $41.8 million. We also adjusted the value of our contingent consideration obligations related to this program to reflect the lower cumulative probabilities of success resulting in a gain of $89.6 million in the third quarter of 2018.
We may recognize additional impairment charges in the future depending upon our ability to advance vixotrigine for the treatment of TGN or other indications.
B Amortization of acquired intangible assets also 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, of which $795.2 million was recognized as an intangible asset in the first quarter of 2017.
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 a $328.2 million 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 revoked 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.
C In June 2018 we closed a new ten-year exclusive agreement with Ionis Pharmaceuticals, Inc. (Ionis) to develop novel antisense oligonucleotide drug candidates for a broad range of neurological diseases for a total payment of $1.0 billion consisting of an upfront payment of $375.0 million and the purchase of approximately 11.5 million shares of Ionis' common stock at a cost of $625.0 million.
The 11.5 million shares of Ionis' common stock were purchased at a premium to their fair value at the transaction closing date. The premium consisted of acquiring the shares at a price above the fair value based on the trailing 10-day weighted-average close price prior to entering into the agreement in April 2018 and the effect of certain holding period restrictions. We recorded an asset of $462.9 million in investments and other assets in our condensed consolidated balance sheets reflecting the fair value of the common stock and a charge of $162.1 million to research and development expense in our condensed consolidated statements of income during the second quarter of 2018, reflecting the premium paid for the common stock.
D Net distribution to noncontrolling interests reflects the $50.0 million payment to Neurimmune SubOne AG (Neurimmune), net of Neurimmune's tax, to further reduce the previously negotiated royalty rates payable on products developed under our amended collaboration and license agreement, including on potential commercial sales of aducanumab, by an additional 5%.
E 2017 corporate strategy and restructuring charges are related to our efforts to create a leaner and simpler operating model.
F The Tax Cuts and Jobs Act of 2017 (2017 Tax Act), which was signed into law in December 2017, has resulted in significant changes to the U.S. corporate income tax system. During the fourth quarter of 2017 we recognized within our provision for income taxes a $1.2 billion provisional estimate under the U.S. Securities and Exchange Commission Staff Accounting Bulletin No. 118. Our provisional estimate included an amount

resulting from a one-time mandatory deemed repatriation tax on accumulated foreign subsidiaries' previously untaxed foreign earnings (the Transition Toll Tax) and amounts related to the impact of remeasuring our deferred tax balances to reflect other aspects of the 2017 Tax Act.
The final determination of the Transition Toll Tax and remeasurement of our deferred assets and liabilities will be completed as additional information becomes available, but no later than one year from the enactment of the 2017 Tax Act. Our preliminary estimate of the Transition Toll Tax and the remeasurement of our deferred tax assets and liabilities is subject to the finalization of management’s analysis related to certain matters, such as developing interpretations of the provisions of the 2017 Tax Act and changes to certain estimates and amounts related to the earnings and profits of certain subsidiaries.
During the three months ended September 30, 2018, we recognized a net reduction of $34.6 million in our estimated Transition Toll Tax, an expense of $5.1 million to remeasure our deferred tax balances and an $11.0 million expense to reflect other aspects of the 2017 Tax Act. During the nine months ended September 30, 2018, the remeasurement of our deferred tax balances resulted in an expense totaling $12.7 million.
Use of Non-GAAP Financial Measures
We 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 form 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, merger-related and other adjustments
We 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 and certain milestones, the amortization of intangible assets, and charges or credits from the fair value remeasurement of our contingent consideration obligations.
2. Hemophilia business separation costs
We 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 initiatives
We 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. (Gain) loss on equity security investments
Effective 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.
5. Other items
We evaluate other items of income and expense on an individual basis, and consider both the quantitative and qualitative aspects of the item, including (i) its size and nature, (ii) whether or not it relates to our ongoing business operations and (iii) whether or not we expect it to occur as part of our normal business on a regular basis. We also include an adjustment to reflect the related tax effect of all reconciling items within our reconciliation of our GAAP to Non-GAAP net income attributable to Biogen Inc. and diluted earnings per share.
