Amendments to Bylaws (Form 8-K)

On January 15, 2026, Topgolf Callaway Brands Corp. (the "Company") changed its corporate name to Callaway Golf Company pursuant to a certificate of amendment to the Company's third restated certificate of incorporation (the "Charter Amendment") filed with the Delaware Secretary of State on January 15, 2026 (the "Name Change"). The Board of Directors of the Company (the "Board") approved the Name Change pursuant to Section 242 of the General Corporation Law of the State of Delaware ("DGCL"). Pursuant to the DGCL, a stockholder vote was not necessary to effectuate the Name Change, and the Name Change does not affect the rights of the Company's stockholders.

On January 15, 2026, following the filing of the Charter Amendment, the Company subsequently filed a fourth restated certificate of incorporation (the "Restated Charter") that combined into one document the Company's prior third restated certificate of incorporation, as amended by the Charter Amendment to reflect the Name Change. The filing of the Restated Charter was authorized by the Board in accordance with Section 245 of the DGCL. The Company also amended and restated its bylaws (the "Amended and Restated Bylaws") effective January 15, 2026 to reflect the Name Change. The only change to the Company's Restated Charter and Amended and Restated Bylaws is the change of the Company's corporate name from Topgolf Callaway Brands Corp. to Callaway Golf Company in each document.

In connection with the Name Change, the Company also announced that it intends for its shares of common stock to cease trading under the ticker symbol "MODG" and begin trading under its new ticker symbol, "CALY", on the New York Stock Exchange, which the Company expects to be effective on or about January 16, 2026.

The foregoing description of the Charter Amendment, the Restated Charter and the Amended and Restated Bylaws does not purport to be complete and is qualified in its entirety by reference to the Charter Amendment, the Restated Charter and the Amended and Restated Bylaws, copies of which are attached hereto as Exhibits 3.1, 3.2 and 3.3, respectively, and incorporated herein by reference.
