On November 2, 2023, the Board of Directors (the “Board”) of MSCI Inc. (the “Company”) approved and adopted amendments (the “Amendments”) to the Company’s Amended and Restated Bylaws (the “Bylaws”), effective as of November 2, 2023, to clarify and implement certain procedural and disclosure requirements for Company shareholders proposing director nominations for consideration at the Company’s annual or special meetings of shareholders in connection with the “universal proxy” rules adopted by the Securities and Exchange Commission pursuant to Rule 14a-19 of the Securities Exchange Act of 1934, as amended. The Amendments also include other technical, conforming, clarifying and modernizing revisions to the Bylaws.

Among other revisions, the Amendments to the Bylaws:

•Enhance the disclosure requirements for director nominations by shareholders to include (a) additional information regarding the shareholder making the director nomination(s), the director nominee(s), and their affiliates and (b) a requirement that the information is updated and supplemented to be accurate and timely;

•Require that any shareholder making director nominations pursuant to Rule 14a-19 include a representation that such shareholder intends to solicit the holders of shares of the Company’s common stock representing at least 67% of the voting power of the shares entitled to vote on the election of directors and provide reasonable evidence of compliance with Rule 14a-19 upon request;

•Require any shareholder soliciting proxies from other shareholders to use a proxy card color other than white, with white proxy cards being reserved for exclusive use by the Board;

•Limit the number of nominees a shareholder may nominate to the number of directors to be elected at the meeting; and

•Remove the limit on the maximum number of directors on the Board.
