During the first quarter of 2025 we began presenting acquired in-process research and development, upfront and milestone expense as a separate line item in our condensed consolidated statements of income. Acquired in-process research and development, upfront and milestone expense includes costs incurred in connection with collaboration and license agreements such as upfront and milestone payments and, when applicable, premiums on equity securities and asset acquisitions of acquired in-process research and development. Biogen does not forecast such acquired in-process research and development, upfront and milestone expense due to the uncertainty of the future occurrence, magnitude and timing of these transactions in any given period.

Results for the quarter ended September 30, 2025, have not been finalized and are subject to our financial statement closing procedures. There can be no assurance that our final results will not differ from the preliminary unaudited estimates described herein.
