•The increase in third quarter 2026 GAAP cost of sales as a percentage of total revenue was driven primarily by higher amortization costs associated with the acquired inventory fair value step-up related to the Reata and Apellis acquisitions, as well as product mix, partially offset by a litigation matter in the third quarter of 2025. The increase in third quarter 2026 Non-GAAP cost of sales as a percentage of total revenue was driven primarily by product mix.
•The increase in third quarter 2026 GAAP and Non-GAAP R&D expense was driven by higher spend on clinical trials, including felzartamab, salanersen and litifilimab, as well as the inclusion of operating expenses from Apellis, and a reduction in R&D funding received from Royalty Pharma.
•The increase in third quarter 2026 GAAP and Non-GAAP SG&A was primarily due to the inclusion of the commercial and management operations of Apellis and an increase in operational spending on sales and marketing activities in support of our U.S. and international product launches.
•Third quarter 2026 GAAP and Non-GAAP acquired IPR&D, upfront and milestone expense was $284 million, primarily related to the acquisition of RayThera Inc.
Other Financial Highlights
•Third quarter 2026 GAAP and Non-GAAP collaboration profit sharing was a net expense of approximately $78 million, which includes approximately $49 million related to Biogen’s collaboration with Samsung Bioepis, and approximately $29 million related to Biogen’s collaboration with Supernus Pharmaceuticals, Inc. for the commercialization of ZURZUVAE in the U.S.
•Third quarter 2026 GAAP other expense was approximately $137 million driven by net interest expense, losses on our equity investments, and higher litigation expenses. Third quarter 2026 Non-GAAP other expense was approximately $91 million primarily driven by net interest expense due to the Apellis acquisition.
•Third quarter 2026 GAAP and Non-GAAP effective tax rates were (128.5)% and 20.0%, respectively. Third quarter 2025 GAAP and Non-GAAP effective tax rates were 16.3% and 17.2%, respectively. The change in our GAAP effective tax rates was primarily driven by the non-deductible IPR&D charge related to the RayThera stock acquisition.
Financial Position and Cash Flows
•Third quarter 2026 net cash flow from operations was approximately $641 million. Capital expenditures were approximately $40 million, and free cash flow, a Non-GAAP financial measure defined as net cash flow from operations less capital expenditures, was approximately $600 million.
•As of September 30, 2026, Biogen had cash and cash equivalents totaling approximately $1.3 billion and approximately $7.7 billion in total debt, resulting in net debt of approximately $6.4 billion.
•For the third quarter of 2026, the Company’s weighted average diluted shares were approximately 148 million and 149 million, used to calculate the Company's GAAP and Non-GAAP diluted EPS, respectively. All unvested equity-based awards are antidilutive for GAAP due to reporting a GAAP net loss for the third quarter 2026.
The Company is advancing multiple potential growth drivers with registrational readouts expected over the next 12 months
•The Company expects to announce top line data from both TOPAZ-1 and TOPAZ-2 Phase 3 studies, evaluating litifilimab in SLE, in the first half of December 2026.
•Additional Phase 3 readouts expected for litifilimab in CLE, felzartamab in antibody mediated rejection in the first half of 2027 and zorevunersen in Dravet syndrome in the third quarter of 2027.

Full Year 2026 Financial Guidance
Biogen is raising the lower end of the reported full year 2026 Non-GAAP diluted EPS guidance range to reflect ongoing business strength and Apellis dilution favorability. Full year 2026 Non-GAAP diluted EPS range is expected as follows:
| FY 2026 Non-GAAP Diluted EPS Guidance | February 2026 | July 2026 | October 2026 | ||||||||
| Underlying guidance | $15.25 to $16.25 | $15.85 to $16.85 | $15.95 to $16.75 | ||||||||
| Expected approximate impact from acquired IPR&D, upfront and milestone charges | -- | ~($3.00) | ~($3.20) | ||||||||
| Expected dilution from the Apellis acquisition | ~($0.85) | ~($0.55) | |||||||||
| Reported Guidance | $15.25 to $16.25 | $12.00 to $13.00 | $12.20 to $13.00 | ||||||||
Full year total revenue is expected to increase by a mid-single digit percentage for 2026 as compared to 2025 driven by continued growth from our Growth Portfolio.
Biogen expects combined Non-GAAP R&D expense and Non-GAAP SG&A expense to be approximately $4.95 billion for the full year 2026.
This guidance also assumes that foreign exchange rates as of October 23, 2026, will remain in effect for the remainder of the year, net of hedging activities.
Other than the acquired IPR&D, upfront and milestone impact expressly stated above, this financial guidance does not include any other potential future acquired IPR&D, upfront and milestone charges, impact from potential acquisitions or business development transactions or pending and future litigation or any impact of potential healthcare reform, as all are difficult to predict. Other important financial considerations will be provided on the conference call and webcast.
Biogen may incur charges, realize gains or losses, or experience other events or circumstances in 2026 that could cause any of these assumptions and expectations to change and/or actual results to vary from this financial guidance.
Biogen does not provide guidance for GAAP reported financial measures (other than revenue) or a
reconciliation of forward-looking Non-GAAP financial measures to the most directly comparable GAAP reported financial measures because the Company is unable without unreasonable effort to predict with reasonable certainty the financial impact of items such as the transaction, integration, and certain other costs related to acquisitions or large business development transactions; unusual gains and losses; potential future asset impairments; gains and losses from equity security investments; and the ultimate outcome of pending or future litigation. These items are uncertain, depend on various factors, and could have a material impact on GAAP reported results for the guidance period. For the same reasons, the Company is unable to address the significance of the unavailable information, which could be material to future results.
Conference Call and Webcast
The Company’s earnings conference call for the third quarter will be broadcast via the internet at 8:30 a.m. ET on October 28, 2026 and will be accessible through the Investors section of Biogen’s website, www.biogen.com. Supplemental information in the form of a slide presentation is also accessible at the same location on the internet and will be subsequently available on the website for at least 90 days.

We supplement our GAAP consolidated financial statements and GAAP financial measures with other financial measures, such as adjusted net income, adjusted diluted earnings per share, revenue growth at constant currency, which excludes the impact of changes in foreign exchange rates and hedging gains or losses, and free cash flow, which is defined as net cash flow from operations less capital expenditures. We believe that these and other Non-GAAP financial measures provide additional insight into the ongoing economics of our business and reflect how we manage our business internally, set operational goals and form the basis of our management incentive programs. Non-GAAP financial measures are in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.

Use of Non-GAAP Financial Measures
We supplement our GAAP consolidated financial statements and GAAP financial measures with other financial measures, such as adjusted net income, adjusted diluted earnings per share, revenue growth at constant currency, which excludes the impact of changes in foreign exchange rates and hedging gains or losses, and free cash flow, which is defined as net cash flow from operations less capital expenditures. We believe that these and other Non-GAAP financial measures provide additional insight into the ongoing economics of our business and reflect how we manage our business internally, set operational goals and form the basis of our management incentive programs. Non-GAAP financial measures are in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP.
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. Acquisitions and divestitures
We exclude transaction, integration and certain other costs related to the acquisition and divestiture of businesses/commercial assets and items associated with the initial consolidation or deconsolidation of variable interest entities. These adjustments include, but are not limited to, the amortization of inventory fair value step-up, amortization and impairment of intangible assets, charges or credits from the fair value remeasurement of our contingent consideration obligations and losses on assets and liabilities held for sale.
2. Restructuring, business transformation and other cost saving initiatives
We exclude costs associated with our execution of certain strategies and initiatives to streamline operations, achieve targeted cost reductions, rationalize manufacturing facilities or refocus research and development activities. These costs may include employee separation costs, retention bonuses, facility closing/abandonment 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 ongoing or future business operations.
3. (Gain) loss on equity security investments
We exclude unrealized and realized gains and losses related to our equity security investments as we do not believe that these components of income or expense have a direct correlation to our ongoing or future business operations.
4. 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 earnings per share - diluted.
