SAFETY INSURANCE GROUP INC

During the three months ended June 30, 2024, none of the officers (as defined in Rule 16a-1(f) of the Securities Exchange Act of 1934) or directors of the Company adopted, terminated ormodified any contract, instruction or written plan for the purchase and sale of our securities that was intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) or any “non-Rule 10b5-1 trading arrangement,” as such term is defined in Item 408(a) of Regulation S-K.

On May 8, 2024, the Compensation Committee of the Board of Directors of the Company (the “Committee”) amended and restated the Company’s Annual Performance Incentive Plan (the “A&R Incentive Plan”). Our executive officers are eligible to participate in the A&R Incentive Plan. The amended terms in the A&R Incentive Plan include (i) removal of the maximum limit on the amount payable to a participant in a plan year, which had not been adjusted since 2007, (ii) removal of provisions relating to Section 162(m) of the Internal Revenue Code of 1986, as amended, which are no longer applicable, (iii) permit the Committee to select other performance objectives applicable to awards in its discretion and (iv) other non-substantive changes. The terms of the A&R Incentive Plan are effective for 2024 performance awards and future awards.

The foregoing description of the A&R Incentive Plan is qualified in its entirety by reference to the Amended & Restated Annual Performance Incentive Plan, a copy of which is filed as Exhibit [10.31] hereto and is incorporated by reference.
