 Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year

On February 2, 2021, the Board of Directors (the “Board”) of 3M Company (the “Company”) approved amended and restated Bylaws of the Company (the “Amended and Restated Bylaws”). Consistent with the General Corporation Law of the State of Delaware (the “DGCL”) and its recent amendments, the Amended and Restated Bylaws, among other things, (a) clarify that the Board may determine that meetings of stockholders may be held by remote communication, at which stockholders and proxy holders may participate and be deemed present in person and vote, whether such meetings are held at a designated place or solely by means of remote communication; (b) clarify that certain documents and notices may be given by electronic transmission; (c) provide that certain electronic networks or databases may be used for records storage; (d) articulate the requirements for maintaining and producing the list of stockholders of record for inspection (including for meetings of stockholders held by remote communication); (e) clarify the timing for giving notice of meetings of stockholders; and (f) provide that any two authorized officers of the Company may sign stock certificates. The Amended and Restated Bylaws also clarify the procedural authorities of the person presiding over meetings of stockholders in connection with the conduct of meetings and the authority to convene, adjourn or recess any such meeting; provide that the number of nominees that a stockholder seeks to nominate for election to the Board under the advance notice provision may not exceed the number of directors to be elected at the meeting; and clarify that the Company shall not be required to include a proxy access nominee in the Company’s proxy materials if such nominee is or has been within the past three years a director or officer of a competitor (as defined by the Clayton Antitrust Act) of the Company. The Amended and Restated Bylaws also include other changes intended to clarify and conform various provisions of the Bylaws to the DGCL and to other provisions of the Bylaws.

This description of the Amended and Restated Bylaws does not purport to be complete and is qualified in its entirety by reference to the text of the Amended and Restated Bylaws, which are attached hereto as Exhibit 3(ii) and incorporated herein by reference.
