Cambridge, Mass. – July 25, 2023


Biogen reports second quarter 2023 results and reaffirms full year 2023 guidance;
LEQEMBI launched in the U.S.

Second quarter revenue $2,456 million; GAAP diluted EPS $4.07; Non-GAAP diluted EPS $4.02
Poised for leadership in Alzheimer's disease with launch of LEQEMBI in the U.S.
New "Fit for Growth" program expected to generate approximately $1 billion in gross operating expense savings, approximately $300 million of which will be reinvested into product launches and R&D programs, resulting in approximately $700 million in net operating expense savings by 2025 - program includes net headcount reduction of approximately 1,000
TECFIDERA regulatory market protection in E.U. extended until February 2, 2025
New data highlight potential benefit of SPINRAZA for the treatment of spinal muscular atrophy in infants and toddlers with unmet clinical needs after gene therapy
R&D pipeline prioritization substantially complete, enabling a sharper focus on high potential opportunities


Commenting on Biogen Inc. (Nasdaq: BIIB) results, President and Chief Executive Officer Christopher A. Viehbacher said:

“In the second quarter, Biogen continued to advance groundbreaking science with the FDA approval of two first-in-class therapies for Alzheimer's disease and ALS, while also delivering on our base business expectations. Biogen’s business is in transition. Accordingly, we have taken a bottom-up view to shift our resources to the areas of greatest value creation. While we will be making significant investments in our newly prioritized pipeline and new product launches, we will also need to invest less in other areas which are no longer growing. With these changes, I believe that Biogen will be better positioned to maximize its growth opportunities going forward.”

(2) Spinal muscular atrophy includes SPINRAZA®.
(3) Alzheimer's disease includes ADUHELM® product revenue and revenue from LEQEMBI® collaboration. Upon commercialization of LEQEMBI, we began recognizing our portion of the profit share on a net basis as a separate component of total revenue within revenue from LEQEMBI collaboration in our condensed consolidated income statements, as we are not the principal.
(4) Other includes FUMADERMTM and QALSODYTM.
(5) Includes revenue from manufacturing of LEQEMBI beginning in the first quarter of 2023.
Expense Summary
(in millions)Q2 '23Q2 '22
GAAP and Non-GAAP cost of sales*
$593$484(22)%
% of Total Revenue24%19%
GAAP and Non-GAAP R&D expense$584$529(11)%
GAAP SG&A expense$548$5734%
Non-GAAP SG&A expense$534$5706%
Note: Percent changes represented as favorable/(unfavorable) versus the prior year period
*Excluding amortization and impairment of acquired intangible assets

Second quarter 2023 GAAP and Non-GAAP cost of sales includes approximately $34 million of idle capacity charges. Second quarter 2022 GAAP and Non-GAAP cost of sales includes approximately $27 million of idle capacity charges. The increase in second quarter 2023 GAAP and Non-GAAP cost of sales as a percentage of total revenue was driven primarily by product mix, particularly the year-over-year increase in contract manufacturing revenue.

Second quarter 2023 GAAP and Non-GAAP R&D expense includes approximately $13 million in estimated study close out costs related to BIIB093 (glibenclamide IV) for large hemispheric infarction and brain contusion.

The decrease in second 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. 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.

Second quarter 2023 GAAP restructuring expense was $34 million.
Other Financial Highlights

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

2


Second quarter 2023 GAAP other income was $121 million, primarily driven by net unrealized gains on strategic equity investments of $107 million. Second quarter 2023 Non-GAAP other income was $15 million, primarily driven by net interest income.

Second quarter 2023 GAAP and Non-GAAP effective tax rates were 16.2% and 15.7%, respectively, as compared to 17.1% and 15.2% in the second quarter of 2022.
Financial Position

Second quarter 2023 net cash flow from operations was $487 million. Capital expenditures were $71 million, and free cash flow, defined as net cash flow from operations less capital expenditures, was $416 million.

As of June 30, 2023, Biogen had cash, cash equivalents, and marketable securities totaling $7,286 million and $6,285 million in total debt, resulting in net cash of $1,002 million.

No shares of the Company’s common stock were repurchased in the second quarter of 2023. As of June 30, 2023, there was $2,050 million remaining under the share repurchase program authorized in October 2020.

For the second quarter of 2023 the Company’s weighted average diluted shares were 146 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 June 30, 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.

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 or future 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

In June, the last patient was enrolled in the Phase 3 study of dapirolizumab pegol in systemic lupus erythematous (SLE). Top line results of the study are expected mid-year 2024. If this study is positive,

Biogen and UCB anticipate that a second Phase 3 study would be needed to support a regulatory filing in SLE.

OPERATING EXPENSE, OTHER (INCOME) EXPENSE, NET, AND INCOME TAX
(unaudited, in millions, except effective tax rate)
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.

A In April 2022 we completed the sale of our 49.9% equity interest in Samsung Bioepis to Samsung BioLogics in exchange for total consideration of approximately $2.3 billion. Under the terms of this transaction, we received approximately $1.0 billion in cash at closing, with approximately $1.3 billion in cash to be deferred over two payments. The first payment of $812.5 million was received in April 2023 and the second payment of $437.5 million is due at the second anniversary of the closing of this transaction.
During the second quarter of 2022 we recognized a pre-tax gain of approximately $1.5 billion related to this transaction, which was recorded in other (income) expense, net in our condensed consolidated statements of income for the three and six months ended June 30, 2022.
B During the second quarter of 2022 we recorded a pre-tax charge of $900.0 million, plus settlement fees and expenses, related to a litigation settlement agreement to resolve a qui tam litigation relating to conduct prior to 2015. This charge is included within other (income) expense, net in our condensed consolidated statements of income for the three and six months ended June 30, 2022.

C During the first quarter of 2022, upon issuance of the final National Coverage Determination 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.
