The following Summary Compensation Table reflects the compensation earned by or paid to the NEOs during 2025, 2024, and 2023.

(1) This column reflects the aggregate grant date fair value of the 2025, 2024, and 2023 grants of performance-based restricted stock unit awards and 2025, 2024, and 2023 grants of performance-based cash incentive unit awards and, for Mr. Brennan, the grant date fair value of his 2024 Equity Make-Whole and Retention Award. The grants of performance-based restricted stock units generally vest three years from the date of grant, conditioned on the attainment of certain pre-determined performance goals. Grants of performance-based cash incentive unit awards generally vest at the payment date, which is as soon as practicable in the calendar year following the end of the calendar year coincident with the end of the three-year performance period. The value of each cash incentive unit initially awarded increases or decreases to reflect the TSR on Selective common stock over the three-year performance period for the award. For the 2025, 2024, and 2023 performance-based cash incentive unit awards, the number of cash incentive units ultimately earned increases or decreases based on (i) cumulative three-year statutory NPW growth relative to the Cash Incentive Unit Peer Group, and (ii) cumulative three-year statutory operating return on policyholder surplus relative to the Cash Incentive Unit Peer Group. Restricted stock unit and cash incentive unit awards are generally subject to forfeiture should the grantee resign or be terminated for cause prior to vesting. However, restricted stock unit and cash incentive unit awards granted to Messrs. Marchioni, Eppers, and Lanza and Ms. Hall will vest upon attainment of the performance condition only, as they have attained their early retirement ages.

The grant date fair values for the performance-based restricted stock unit and performance-based cash incentive unit awards granted to the NEOs are as follows:

The aggregate grant date fair value reported in this column assumes the following: (i) the predetermined performance goals for the restricted stock unit grants are probable of being attained; (ii) initial per unit values for the cash incentive unit awards of $100; and (iii) a 100% peer group unit multiplier for cash incentive unit awards. For further discussion of the fair value calculation of the awards in this column, please refer to Note 16. “Share-Based Payments” to the consolidated financial statements in our 2025 Annual Report. The maximum value assuming the highest level of performance conditions for the performance-based restricted stock units are consistent with the amounts above. Although the maximum number of performance-based cash incentive units potentially issuable is 150% of the original grant for the 2023, 2024, and 2025 grants, the ultimate maximum value of the 2023, 2024, and 2025 grants cannot be determined at this time because the initial value of each unit is adjusted based on the TSR of Selective common stock over the grant’s three-year performance period. Mr. Brennan was not granted performance-based restricted stock unit or performance-based cash incentive unit awards in 2024, as he received the 2024 Equity Make-Whole and Retention Award.

(2) Amounts in this column are ACIP awards to the NEOs earned in 2025 and paid in 2026, earned in 2024 and paid in 2025 (except for Mr. Brennan), and earned in 2023 and paid in 2024. These awards were granted under the Cash Incentive Plan. Mr. Brennan did not receive an ACIP payment for 2024; instead, he received the 2024 Make-Whole ACIP Payment given his date of hire in October 2024.

(3) Amounts in this column reflect the actuarial increase in the present value of each NEO’s pension benefits under all defined benefit pension plans of SICA, determined using the same interest rate and mortality assumptions as those used for financial statement reporting purposes. There were no changes to the benefit formulas under the defined pension benefit plans in 2025, as the plans were amended to cease further accruals effective as of March 31, 2016. The changes in pension values reported in this column are primarily attributable to a decrease in the discount rate used to calculate present value and the use of the most-recently released mortality tables. Based on Messrs. Brennan’s and Eppers’ hire dates, they are not eligible to participate in SICA’s defined benefit pension plans. There were no above-market or preferential earnings on deferred compensation under SICA’s nonqualified deferred compensation program.

(4) For 2025, amounts in this column for each NEO reflect the following, which are based on actual incremental Company costs of providing these items to the NEOs (amounts in this footnote may not exactly match the figures in the Summary Compensation Table due to rounding):

(5) Amount reflects the first and second installments of Mr. Brennan’s 2024 Cash Make-Whole and Retention Award that were paid in 2024 and 2025, respectively, pursuant to the terms of his employment agreement.
