Amendment Description | This Current Report on Form 8-K/A (this “Amendment”) amends the Current Report on Form 8-K of Biogen Inc. (the “Company”) filed with the U.S. Securities and Exchange Commission on June 29, 2023 (the “Original Form 8-K”). The Original Form 8-K reported the final voting results of the Company’s 2023 Annual Meeting of Stockholders held on June 26, 2023 (the “Annual Meeting”). The sole purpose of this Amendment is to disclose the Company’s decision regarding whether stockholder votes to approve the compensation of its named executive officers required by Section 14A(a)(1) of the Securities Exchange Act of 1934 and Rule 14a-21(a) promulgated thereunder (the “Say-on-Pay Vote”) should be held every one, two or three years (the “Say-on-Frequency Proposal”). No other changes have been made to the Original Form 8-K. |
