Biogen Inc. (NASDAQ: BIIB) today reported fourth quarter and full year 2023 financial results. Commenting on the results, President and Chief Executive Officer Christopher A. Viehbacher said:

“2023 was a year of transformation for Biogen as we saw approval for four first-in-class medicines while we realigned our cost structure, remained prudent in allocating shareholder capital, and reprioritized our pipeline. We believe with these key elements in place we are now well positioned to return Biogen to sustainable growth. As we look to 2024, our focus is on operational execution, including building upon the progress of our recent new product launches. We believe this will allow us to continue to advance our goal of a new Biogen that creates enhanced value for patients and our shareholders.”

*Excluding amortization and impairment of acquired intangible assets

# As referenced above, beginning in the third quarter of 2023, Biogen's 50% share of all global pre- and post-commercialization sales & marketing expenses for the LEQEMBI Collaboration will be presented within SG&A expense and will no longer present the post-commercialization portion of these expenses as a reduction to revenue.

•Fourth quarter 2023 GAAP and Non-GAAP cost of sales includes approximately $52 million of idle capacity charges. Fourth quarter 2022 GAAP and Non-GAAP cost of sales includes approximately $36 million of idle capacity charges. The increase in fourth quarter 2023 GAAP and Non-GAAP cost of sales as a percentage of total revenue was driven primarily by product mix.

•Full year 2023 GAAP and Non-GAAP cost of sales includes approximately $165 million of idle capacity charges. Full year 2022 GAAP and Non-GAAP cost of sales includes approximately $119 million of idle capacity charges and approximately $286 million in charges associated with the write-off of inventory and purchase commitments in excess of forecasted demand related to ADUHELM. The increase in full year 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.

•Fourth quarter 2023 GAAP and Non-GAAP R&D expense includes approximately $45 million related to Biogen's portion of R&D expense related to the LEQEMBI Collaboration and approximately $60 million in close out costs related to ADUHELM.

•Full year 2023 GAAP and Non-GAAP R&D expense includes approximately $186 million related to Biogen's portion of R&D expense related to the LEQEMBI Collaboration.

•Fourth quarter 2023 GAAP and Non-GAAP SG&A includes approximately $56 million related to Biogen's portion of SG&A expense related to the LEQEMBI Collaboration.

•Full year 2023 GAAP and Non-GAAP SG&A includes approximately $152 million related to Biogen's portion of SG&A expense related to the LEQEMBI Collaboration.

•Fourth quarter and full year 2023 GAAP restructuring expense was approximately $99 million and approximately $219 million, respectively.

Other Financial Highlights

•Fourth quarter 2023 GAAP and Non-GAAP collaboration profit sharing was a net expense of approximately $54 million, which includes approximately $53 million of net profit sharing expense related to Biogen’s collaboration with Samsung Bioepis, and approximately $1 million of net profit sharing expense related to Biogen’s collaboration with Sage Therapeutics related to the commercialization of ZURZUVAE in the U.S.

•Full year 2023 GAAP and Non-GAAP collaboration profit sharing was a net expense of approximately $219 million, which includes approximately $224 million of net profit sharing expense related to Biogen’s collaboration with Samsung Bioepis, partially offset by net reimbursement of approximately $5 million from Sage Therapeutics related to the commercialization of ZURZUVAE in the U.S.

•Fourth quarter 2023 GAAP and Non-GAAP other expense was approximately $67 million and approximately $62 million, respectively, primarily driven by net interest expense.

•Full year 2023 GAAP other expense was approximately $316 million, primarily driven by net unrealized losses on strategic equity investments of approximately $270 million. Full year 2023 Non-GAAP other expense was approximately $14 million, primarily driven by foreign exchange rate losses, partially offset by net interest income.

•Fourth quarter 2023 GAAP and Non-GAAP effective tax rates were 14.7% and 17.0%, respectively. Fourth quarter 2022 GAAP and Non-GAAP effective tax rates were 9.0% and 14.9%, respectively.

•Full year 2023 GAAP and Non-GAAP effective tax rates were 10.4% and 15.2%, respectively. Full year 2022 GAAP and Non-GAAP effective tax rates were 17.6% and 15.3%, respectively.

Financial Position

•Fourth quarter 2023 net cash flow from operations was approximately $13 million, which includes a payment of approximately $393 million for equity-based compensation attributable to the post-acquisition service period related to the Reata Pharmaceuticals, Inc. (Reata) transaction. Capital expenditures were approximately $65 million, and free cash flow, defined as net cash flow from operations less capital expenditures, was a net cash outflow of approximately $53 million.

•Full year 2023 net cash flow from operations was approximately $1.5 billion, and includes the aforementioned payment of approximately $393 million related to Reata. Capital expenditures were approximately $277 million, and free cash flow, defined as net cash flow from operations less capital expenditures, was approximately $1.3 billion.

•As of December 31, 2023, Biogen had cash, cash equivalents, and marketable securities totaling approximately $1.0 billion with approximately $6.9 billion in total debt, resulting in net debt of approximately $5.9 billion. This reflects all purchase payments related to the Reata transaction and a paydown of approximately $350 million of the $1 billion term loan related to our acquisition of Reata.

•No shares of the Company’s common stock were repurchased in the fourth quarter of 2023. As of December 31, 2023, there was approximately $2.1 billion remaining under the share repurchase program authorized in October 2020.

•For the fourth quarter of 2023 the Company’s GAAP weighted average diluted shares were 146 million. For full year 2023 the Company’s GAAP weighted average diluted shares were 146 million.

Full Year 2024 Financial Guidance

For the full year 2024, Biogen expects a Non-GAAP diluted EPS guidance range as follows:


						Full Year 2024 Guidance
Non-GAAP diluted EPS						$15.00 to $16.00 Reflecting growth of ~5% at the mid-point*

*Versus reported full year 2023

While total revenue is expected to decline by a low- to mid-single digit percentage, Biogen expects core pharmaceutical revenue, defined as product revenue plus Biogen's 50% share of net LEQEMBI product revenue and cost of sales, including royalties, to be relatively flat for 2024 compared to 2023 as further declines in multiple sclerosis product revenue are expected to be offset by increases in revenue from new product launches.

As of December 31, 2023, batch commitments related to the 2020 sale of Hillerød, Denmark manufacturing operations to FUJIFILM have been satisfied. Biogen expects contract manufacturing revenue to be significantly lower in 2024 compared to 2023.

As a result of these dynamics affecting revenue, along with lower expected idle capacity charges, Biogen expects an improvement in the cost of sales as a percentage of total revenue for 2024 compared to 2023.

For 2024 compared to 2023, Biogen expects operating income to grow at a low-double digit percentage. This is expected to be driven by improved cost of sales as a percentage of revenue, as well as lower operating expenses as a result of the Company's Fit for Growth program. The Fit for Growth program is expected to generate approximately $1 billion in gross savings and $800 million net of reinvestment by 2025. Since the program was initiated in 2023, approximately $200 million of savings have been achieved, and Biogen expects to realize approximately half of the overall net savings by the end of 2024 with the balance by the

end of 2025. These amounts do not include Biogen's 50% share of sales and marketing expenses for the LEQEMBI Collaboration.

This guidance also assumes that foreign exchange rates as of February 9, 2024, will remain in effect for the remainder of the year, net of hedging activities. Other modeling considerations will be provided on the conference call and webcast.

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 2024 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.

Conference Call and Webcast

The Company’s earnings conference call for the fourth quarter will be broadcast via the internet at 8:00 a.m. ET on February 13, 2024 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.

OPERATING EXPENSE, OTHER (INCOME) EXPENSE, NET, AND INCOME TAX EXPENSE

(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.

GAAP TO NON-GAAP RECONCILIATION NOTES

(unaudited, in millions, except per share amounts)

A Share-based compensation expense reflects the accelerated vesting of awards previously granted to Reata Pharmaceuticals Inc. (Reata) employees as a result of our acquisition of Reata in the third quarter of 2023. We paid pay approximately $983.9 million in cash for Reata's outstanding equity awards, inclusive of employer taxes, of which approximately $590.5 million was attributable to pre-acquisition services and is therefore reflected as a component of total purchase price paid. Of the $983.9 million paid to Reata's equity award holders, we recognized approximately $393.4 million as compensation attributable to the post-acquisition service period, of which $196.4 million was recognized as a charge to selling, general and administrative expense with the remaining $197.0 million as a charge to research and development expense within our consolidated statements of income for the year ended December 31, 2023.

B During the fourth quarter of 2022 we discontinued further development of vixotrigine based on regulatory, development and commercialization challenges. For the year ended December 31, 2022, we recognized an impairment charge of approximately $119.6 million related to vixotrigine for the potential treatment of DPN, reducing the remaining book value of this IPR&D intangible asset to zero.

C 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 deferred payment of $812.5 million was received in April 2023 and the second deferred payment of $437.5 million is due at the second anniversary of the closing of this transaction in April 2024.

Prior to the sale, the carrying value of our investment in Samsung Bioepis totaled $581.6 million. For the year ended December 31, 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 consolidated statements of income.

D 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 consolidated statements of income for the year ended December 31, 2022.

E 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 this 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.

F In September 2022 we completed the sale of our building and land parcel located at 125 Broadway for an aggregate sales price of approximately $603.0 million, which is inclusive of a $10.8 million tenant allowance. This sale resulted in a pre-tax gain on sale of approximately $503.7 million, net of transaction costs, which is reflected within gain on sale of building in our consolidated statements of income for the year ended December 31, 2022.

Use of Non-GAAP Financial Measures

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.
