Item 1.01 Entry into a Material Definitive Agreement.

On May 21, 2026, each of Thomas G. Dundon and Mark D. Mandel were elected to the Board of Directors (“Board”) of Callaway Golf Company (the “Company”) at the 2026 Annual Meeting of Shareholders (the “Annual Meeting”). Following the election, also on May 21, 2026, the Company and each of Mr. Dundon and Mr. Mandel entered into the Company’s standard form of indemnification agreement for non-employee directors (each. an “Indemnification Agreement”). Under each Indemnification Agreement, to the fullest extent permitted by the General Corporation Law of the State of Delaware, the Company agrees to indemnify the applicable director against any threatened, pending or completed action, suit or proceeding, by reason of his status as a current or former director, employee or agent of the Company or any other entity on behalf of which he is or was serving at the request of the Company or any subsidiary of the Company, and against any expense, liability and loss (including attorneys’ fees), judgments, fines and amounts paid in settlement actually or reasonably incurred by the applicable director in connection with such action, suit or other proceeding. Each Indemnification Agreement also provides for, among other things, the advancement by the Company of expenses incurred by the applicable director in such action, suit or other proceeding, subject to reimbursement by the applicable director of such advanced expenses in the event he is ultimately determined, after final disposition of an action, suit or proceeding, not to be entitled to indemnification. In addition, each Indemnification Agreement provides procedures for the determination of the applicable director’s right to receive indemnification and the advancement of expenses.

The foregoing description is qualified in its entirety by reference to the full text of the Indemnification Agreements, copies of which are attached as Exhibit 10.1 and Exhibit 10.2 hereto and incorporated herein by reference.
