Item 5.03 Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year. On February 18, 2026, the Board approved amended and restated bylaws of the Company (as so amended and restated, the “Amended and Restated Bylaws”). The Amended and Restated Bylaws reflect an updated description of the role of the President, such that the President’s duties may be assigned by the Board or the Chief Executive Officer, rather than the Board alone, and the President’s performance of his duties is subject to the direction of the Board or the Chief Executive Officer, rather than the Board alone. The Amended and Restated Bylaws also include an updated definition of “Principal Competitor,” as such term is used in the advance notice provisions. Previously, the definition of “Principal Competitor” referenced competitors of the Company identified in certain filings with the Securities and Exchange Commission made by the Company. Pursuant to the Amended and Restated Bylaws, “Principal Competitor” means any entity that the Board determines, in good faith, provides products or services that compete with or are alternatives to the principal products produced or services provided by the Company or its affiliates. The foregoing description of the Amended and Restated Bylaws does not purport to be complete and is qualified in its entirety by reference to the full text of the Amended and Restated Bylaws, a copy of which is filed with this Current Report on Form 8-K as Exhibit 3.1 and is incorporated herein by reference.
