During the quarter ended June 30, 2024, none of our directors or executive officers adopted orterminated any contract, instruction or written plan for the purchase or sale of AAG securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement.”

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

On July 24, 2024, the Board of Directors of AAG voted to adopt the Fourth Amended and Restated Bylaws (as amended prior to the date hereof, the “A&R Bylaws”), which became effective immediately upon adoption. The A&R Bylaws amend and restate AAG’s previously existing bylaws in their entirety to, among other things, (i) remove certain informational requirements concerning stockholders seeking to nominate directors and bring matters before an annual meeting, (ii) narrow the scope of persons that the information set forth in (i) must be provided for and (iii) implement technical amendments to the procedures of preparing for, holding and adjourning a meeting of stockholders. The foregoing is qualified in its entirety by reference to the text of the A&R Bylaws, a copy of which is filed as Exhibit 3.1 to this Quarterly Report on Form 10-Q.
