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

On February 17, 2023, the Board of Directors of Mueller Industries, Inc. (the “Company”) approved amendments to the Company’s bylaws primarily in response to recent changes to the rules of the Securities and Exchange Commission and the Delaware General Corporation Law. A summary of these amendments is set forth below:

•Annual Meetings of Stockholders: Article II, Section 11 was amended to update the procedural mechanics for stockholder nominations of directors in accordance with Rule 14a-19 under the Securities Exchange Act of 1934, as amended, and to make certain other changes related to the information required to be provided in connection with such nominations;

•List of Stockholders: Article II, Section 8 was updated in order to remove a requirement that the list of stockholders be available during a meeting of stockholders; and

•Number of Board Members: Article III, Section 1 was updated to reduce the number of directors from nine (9) to eight (8), to reflect the current size of the Board.

The foregoing summary does not purport to be a complete description of the Company’s Amended and Restated By-Laws, as adopted and effective on February 17, 2023 (the “Restated By-Laws”) and is qualified in its entirety by reference to the Restated By-Laws, a copy of which is filed herewith as Exhibit 3.1 to this Current Report on Form 8-K and is incorporated by reference in this Item 5.03.

Section 10.Consent of Stockholders in Lieu of Meeting.

(A)Unless otherwise provided in the Certificate of Incorporation of the Corporation, any action which may be taken at any annual or special meeting of stockholders may be taken without a meeting, without prior notice and without a vote, if a consent in writing, setting forth the action so taken, shall be signed, in person or by proxy, by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take the action at a meeting at which all shares entitled to vote thereon were present and voted in person or by proxy.

(B)In order that the Corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, the Board of Directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted by the Board of Directors, and which date shall not be more than ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board of Directors. Any stockholder of record seeking to have the stockholders authorize or take corporate action by written consent shall, by written notice to the Secretary, request the Board of Directors to fix a record date. The Board of Directors shall promptly, but in all events within ten (10) days after the date on which such a request is received, adopt a resolution fixing the record date.

- 2 -

that either (1) the date of the annual meeting is advanced by more than thirty (30) days or delayed by more than thirty (30) days from such anniversary date or (2) no annual meeting of stockholders was held in the previous year, notice by the stockholder to be timely must be so delivered not earlier than the close of business on the one hundred fiftieth (150th) day prior to such annual meeting and not later than the close of business on the later of (x) the one hundred twentieth (120th) day prior to such annual meeting or (y) the tenth (10th) day following the day on which public announcement of the date of such meeting is first made. The public announcement of a postponement or adjournment of an annual meeting shall not commence a new time period for the giving of a stockholder’s notice as described above. Such stockholder’s notice shall set forth (a) as to each person whom the stockholder proposes to nominate for election or reelection as a director all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors, or is otherwise required, in each case pursuant to Regulation 14A under the Securities Exchange Act of 1934 (the “Exchange Act”) (including such person’s written consent to being named in the proxy statement as a nominee and to serving as a director if elected), or any successor rule or regulation; (b) if the stockholder giving the notice or the beneficial owner, if any, on whose behalf the nomination is made intends to solicit proxies in support of nominees other than the Corporation’s nominees (unless such solicitation would not be subject to Rule 14a-19 under the Exchange Act), a statement that such person intends to solicit holders of the Corporation’s stock representing at least the percentage of the Corporation’s outstanding stock required under Rule 14a-19 under the Exchange Act in support of director nominees other than the Corporation’s nominees; (c) as to any other business that the stockholder proposes to bring before the meeting, a brief description of the business desired to be brought before the meeting, the reasons for conducting such business at the meeting and any material interest in such business of such stockholder and the beneficial owner, if any, on whose behalf the proposal is made; and (d) as to the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is made (i) the name and address of such stockholder, as they appear on the Corporation’s books, and of such beneficial owner and (ii) the class and number of shares of the Corporation which are owned beneficially and of record by such stockholder and such beneficial owner.

(3)Notwithstanding anything in the second sentence of paragraph (A)(2) of this Section 11 to the contrary, in the event that the number of directors to be elected to the Board of Directors is increased and there is no public announcement naming all of the nominees for director or specifying the size of the increased Board of Directors made by the Corporation at least ten (10) days prior to the last day a stockholder may deliver a notice of nomination in accordance with Section 11(A)(2), a stockholder’s notice required by this Section 11 shall also be considered timely, but only with respect to nominees for any new positions created by such increase, if it shall be delivered to the Secretary of the Corporation at the principal executive offices of the Corporation not later than the close of business on the tenth (10) day following the day on which such public announcement is first made by the Corporation.

(B)Special Meetings of Stockholders. Only such business shall be conducted at a special meeting of stockholders as shall have been brought before the meeting pursuant to the Corporation’s notice of meeting pursuant to Article II, Section 3 of these By-Laws. Nominations of persons for election to the Board of Directors may be made at a special meeting of stockholders at which directors are to be elected pursuant to the Corporation’s notice of meeting (a) by or at the direction of the Board of Directors or (b) by any stockholder of the Corporation who is entitled to vote at the meeting, who has complied with the notice procedures set forth in this Section 11 and who was a stockholder of record at the time such notice was delivered to the Secretary of the Corporation. Nomination by stockholders of persons for election to the Board of Directors may be made at such a special meeting of stockholders if the stockholder’s notice required by paragraph (A)(2) of this Section 11 shall have been delivered to the Secretary at the principal executive offices of the Corporation not earlier than the ninetieth (90) day prior to such special meeting and not later than the close of business on the later of the sixtieth (60) day prior to such special meeting or the tenth (10) day following the day on which public announcement is first made of the date of the special meeting.

(C)General.

(1)Only persons who are nominated in accordance with the procedures set forth in this Section 11 shall be eligible to serve as directors and only such business shall be conducted at a meeting of stockholders as shall have been brought before the meeting in accordance with the procedures set forth in this Section 11. Except as otherwise provided by law, the Certificate of Incorporation, as amended, or these By-Laws, the chairman of the meeting shall have the power and duty to determine whether a nomination or any business proposed to be brought before the meeting was made in accordance with the procedures set forth in this Section 11 and, if any proposed nomination or business is not in compliance with this Section 11, to declare that such defective proposal or nomination shall be disregarded.

(2)For purposes of this By-Law, “public announcement” shall mean disclosure in a press release reported by the Dow Jones News Service, Associated Press or comparable national news service or in a document publicly filed by the Corporation with the Securities and Exchange Commission pursuant to Section 13, 14 or 15(d) of the Exchange Act.

(3)If any stockholder (or beneficial owner, if any, on whose behalf such stockholder is acting) (1) provides notice pursuant to Rule 14a-19(b) under the Exchange Act with respect to any proposed director nominee, and (2) subsequently fails to comply with the requirements of Rule 14a-19(a)(2) or Rule 14a-19(a)(3) under the Exchange Act (or fails to timely provide reasonable evidence sufficient to satisfy the Corporation that such stockholder or beneficial owner has met the requirements of Rule 14a-19(a)(3) under the Exchange Act in accordance with the following sentence), then notwithstanding anything to the contrary, unless otherwise required by law, the nomination of each such proposed nominee shall be disregarded, notwithstanding that proxies or votes in respect of the election of such proposed nominees may have been received by the Corporation (which proxies and votes shall be disregarded). Upon request by the Corporation, if any stockholder provides notice pursuant to Rule 14a-19(b) under the Exchange Act, such stockholder shall deliver to the Corporation, no later than five business days prior to the applicable meeting, reasonable evidence that it has met the requirements of Rule14a-19(a)(3) under the Exchange Act.

(4)Notwithstanding the foregoing provisions of this Section 11, a stockholder shall also comply with all applicable requirements of the Exchange Act and the rules and regulations thereunder with respect to the matters set forth in this Section 11. Nothing in this Section 11 shall be deemed to affect any rights of stockholders to request inclusion of proposals in the Corporation’s proxy statement pursuant to Rule 14a-8 under the Exchange Act.
