First quarter 2023 GAAP and Non-GAAP cost of sales includes approximately $45 million of idle capacity charges. First quarter 2022 GAAP and Non-GAAP cost of sales includes approximately $275 million of charges resulting from ADUHELM inventory write-offs as well as approximately $45 million of idle capacity charges.

The decrease in first quarter 2023 GAAP and Non-GAAP SG&A expense was driven primarily by cost savings initiatives, partially offset by investments to support new product launches and $31 million related to the termination of the co-promotion agreement with Eisai for Biogen’s multiple sclerosis

products in Japan. Beginning in the first quarter of 2023 the reimbursement to Eisai for Biogen’s share of U.S. LEQEMBI SG&A expense is reflected as a component of revenue rather than SG&A.
Other Financial Highlights

First quarter 2023 GAAP and Non-GAAP collaboration profit sharing was a net expense of $57 million, all related to Biogen’s collaboration with Samsung Bioepis.

First quarter 2023 GAAP other expense was $69 million, primarily driven by net unrealized losses on strategic equity investments of $77 million. First quarter 2023 Non-GAAP other income was $8 million, primarily driven by net interest income.

First quarter 2023 GAAP and Non-GAAP effective tax rates were 12% and 14%, respectively, as compared to 36% and 16% in the first quarter of 2022. First quarter 2023 GAAP and Non-GAAP tax rates benefited from the resolution of an uncertain tax matter. Lower unrealized losses in our equity investments favorably impacted the first quarter 2023 GAAP effective tax rate as compared to the first quarter of 2022. The first quarter 2022 GAAP effective tax rate included an $85 million expense related to a valuation allowance on Neurimmune SubOne AG’s tax basis in ADUHELM with an equal and offsetting amount assigned to noncontrolling interest, resulting in zero net impact to net income attributable to Biogen Inc.
Financial Position

First quarter 2023 cash flow from operations was $455 million. Capital expenditures were $67 million, and free cash flow, defined as cash flow from operations less capital expenditures, was $389 million.

As of March 31, 2023, Biogen had cash, cash equivalents, and marketable securities totaling $6,020 million and $6,283 million in total debt, resulting in net debt of $263 million. Subsequent to the end of the quarter, Biogen received an installment payment of approximately $813 million related to the sale of its equity stake in Samsung Bioepis, which is not included in these figures.

No shares of the Company’s common stock were repurchased in the first quarter of 2023. As of March 31, 2023, there was $2,050 million remaining under the share repurchase program authorized in October 2020.

For the first quarter of 2023 the Company’s weighted average diluted shares were 145 million.

Full Year 2023 Financial Guidance

For the full year 2023, Biogen is reaffirming its guidance ranges as follows:
Full Year 2023 Guidance
Total revenueMid-single digit percentage decline versus reported full year 2022
Non-GAAP diluted EPS$15.00 to $16.00

This guidance assumes that foreign exchange rates as of March 31, 2023, will remain in effect for the remainder of the year, net of hedging activities.

This financial guidance does not include any impact from potential acquisitions or large business development transactions or pending and future litigation, as all are hard to predict, or any impact of potential tax or healthcare reform. Biogen may incur charges, realize gains or losses, or experience other events or circumstances in 2023 that could cause any of these assumptions to change and/or actual results to vary from this financial guidance.

3


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 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 our equity security investments; and the ultimate outcome of pending significant litigation without unreasonable effort. 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.

Recent Developments

Today Biogen announced that it will terminate its involvement in the development of BIIB093 (glibenclamide IV), currently in a Phase 3 study for large hemispheric infarction and a Phase 2 study for brain contusion, due to operational challenges and other strategic considerations. Under the terms of its agreement, Biogen has sent a letter of termination to Remedy Pharmaceuticals (Remedy), the original developer of BIIB093. Remedy has 30 days to exercise its reversion right to assume development of both programs. During this period, both studies will continue as planned. Biogen expects its decision to result in a modest reduction to full year 2023 R&D expense with more meaningful savings expected in subsequent years.

Today Biogen announced that it is pausing the initiation of a Phase 2b study for BIIB131 (TMS-007) for acute ischemic stroke and is assessing whether to initiate this study.

Today Biogen announced that, as part of its ongoing R&D prioritization initiative, it is discontinuing development of BIIB132 in spinocerebellar ataxia type 3.

A During the first quarter of 2022, upon issuance of the final NCD related to ADUHELM, we recorded an increase in a valuation allowance of approximately $85.0 million to reduce the net value of a previously recorded deferred tax asset to zero.
This adjustment to our net deferred tax asset is recorded with an equal and offsetting amount assigned to net income (loss) attributable to noncontrolling interests, net of tax in our condensed consolidated statements of income, resulting in a zero net impact to net income attributable to Biogen Inc.

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 and items associated with the initial consolidation or deconsolidation of variable interest entities. These adjustments include, but are not limited to, the 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 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.
