# SECOND QUARTER 2025 FINANCIAL RESULTS AND BUSINESS UPDATE
# FORWARD-LOOKING STATEMENTS
This presentation and the discussions during this conference call contains forward-looking statements, relating to: our strategy and plans; potential of, and expectations for, our commercial business and pipeline programs; capital allocation and investment strategy; clinical development programs, clinical trials, and data readouts and presentations; regulatory discussions, submissions, filings, and approvals; the potential benefits, safety, and efficacy of our and our collaboration partners’ products and investigational therapies; the anticipated benefits and potential of investments, optimization of the cost structure including our "Fit for Growth" program, actions to improve risk profile and productivity of R&D pipeline, collaborations, and business development activities; our future financial and operating results; and our 2025 financial guidance. These forward-looking statements may be accompanied by such words as “aim,” “anticipate,” “assume,” “believe,” “contemplate,” “continue,” “could,” “estimate,” “expect,” “forecast,” “goal,” “guidance,” “hope,” “intend,” “may,” “objective,” “outlook,” “plan,” “possible,” “potential,” “predict,” “project,” “prospect,” “should,” “target,” “will,” “would,” and other words and terms of similar meaning. Drug development and commercialization involve a high degree of risk, and only a small number of research and development programs result in commercialization of a product. Results in early-stage clinical trials may not be indicative of full results or results from later stage or larger scale clinical trials and do not ensure regulatory approval. You should not place undue reliance on these statements.

These statements speak only as of the date of this presentation and the discussions during this conference call and are based on information and estimates available to us at this time. Should known or unknown risks or uncertainties materialize or should underlying assumptions prove inaccurate, actual results could vary materially from past results and those anticipated, estimated or projected. Investors are cautioned not to put undue reliance on forward-looking statements. A further list and description of risks, uncertainties and other matters can be found in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 and in our subsequent reports on Form 10-Q and Form 10- K, in each case including in the sections thereof captioned “Note Regarding Forward-Looking Statements” and “Item 1A. Risk Factors,” and in our subsequent reports on Form 8-K. Except as required by law, we do not undertake any obligation to publicly update any forward-looking statements whether as a result of any new information, future events, changed circumstances or otherwise.
# NON-GAAP FINANCIAL INFORMATION
This presentation and the discussions during this conference call include certain financial measures that were not prepared in accordance with accounting principles generally accepted in the U.S. (GAAP), including 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. Additional nformation regarding the GAAP and Non-GAAP financial measures and a reconciliation of the GAAP to Non-GAAP financial measures can be found in the appendix of this presentation and in the Q2 2025 earnings release and related financial tables posted on the Investors section of Biogen.com. 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.
We do 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 we are unable to predict with reasonable certainty the financial impact of items such as the transaction, ntegration, and other costs related to acquisitions or business development transactions; unusual gains and losses; potential future asset impairments; gains and losses from our equity security investments; the ultimate outcome of litigation and other non-recurring items. 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, we are unable to address the significance of the unavailable information, which could be material to future results.

# WE RAN A PHASE 1B STUDY TO EVALUATE ONCE YEARLY SALANERSEN IN SMA PATIENTS WHO PREVIOUSLY RECEIVED GENE THERAPY
Salanersen is a novel ASO leveraging the same mechanism of action of SPINRAZA but designed for high potency to address the remaining unmet need in SMA

# Primary Endpoint
Safety (incidence of AEs / SAEs)
# Key Secondary Endpoint
• Pharmacokinetics (serum and CSF)
# Key Exploratory Endpoints
Neurofilaments
WHO motor milestones Motor function assessments • Older: HFMSE, RULM • Younger: HINE-2, CHOP-INTEND
# pants must have suboptimal clinical status in $\\geq 1$ of 4 domains as determined by study investigator at screening:
• Motor function • Respiratory function • Swallowing or feeding ability for age • Other
# INTERIM PHASE 1B RESULTS SUPPORT ADVANCEMENT TO PHASE 3 ANDHIGHLIGHT SALANERSEN’S POTENTIAL TO TRANSFORM SMA CARE
Data shows that salanersen resulted in substantial slowing of neurodegeneration and clinically meaningful improvements in children previously treated with gene therapy
# Interim Phase 1b results
Clinically meaningful improvements in motor function from baseline to 1-year on the HFMSE and the RULM scales $( \\mathsf { n } { = } 8 ) ^ { 1 }$ $70 %$ reduction in NfL at 6 months and sustained through 1-year $( n = 2 4 )$ 2 Cumulative Phase 1 data indicate that salanersen has a generally well tolerated safety profile

Please see Biogen’s Q2 2025 earnings release, available at the Investors section of Biogen’s website at investors.biogen.com, for additional 2025 financial guidance assumptions.
This financial guidance incorporates the Company's view that Biogen's 2025 financial outlook is not currently expected to be materially impacted by potential pharmaceutical tariffs as announced by the U.S. Administration on April 2, 2025, even if the exemption for pharmaceuticals were to be removed. This is based on both a significant proportion of U.S. revenue being derived from products which have manufacturing operations in the United States, and the Company's current global inventory positions. The U.S. and international tariff landscape remains uncertain, and this guidance does not include contemplation of any new tariffs.
This financial guidance does not include any impact from potential acquisitions or business development transactions or pending and future litigation or any impact of potential tax or healthcare reform, as all are hard to predict. Biogen may incur charges, realize gains or losses, or experience other events or circumstances in 2025 that could cause any of these assumptions to change and/or actual results to vary from this financial guidance.

FY $\\mathbf { \\sigma } = \\mathbf { \\sigma }$ full year
# UPDATED KEY CONSIDERATIONS FOR FULL YEAR 2025 FINANCIAL GUIDANCE
# Total Revenue
Increased expected full year 2025 total revenue to be approximately flat, at constant currency, versus FY 2024, up from a mid-single digit decline previously
# MS Revenue
Excluding favorability from inventory and one-time GTN adjustments of $$ 75M$ , U.S. revenue trends for the second half of 2025 expected to be roughly in line with the first half Expect increased pace of erosion on our ex-U.S. MS business in the second half of 2025, particularly for TECFIDERA in the E.U.
# Contract Manufacturing Revenue
Expect FY 2025 contract manufacturing revenue to be roughly consistent with FY 2024 Expect minimal Q4 revenue due to planned plant maintenance
# Fit for Growth

# 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 change 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 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 on 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.
