Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On October 29, 2025, the Board of Directors (the “Board”) of Selective Insurance Group, Inc. (the “Company”) increased the size of the Board from 11 members to 12 members and appointed Julie Parsons as a non-employee director of the Company, effective November 3, 2025 (the “Appointment”). The Board also named Ms. Parsons to the Board’s Risk Committee and Compensation and Human Capital Committee. Ms. Parsons’ term will continue until the Company’s 2026 Annual Meeting of Stockholders (the “2026 Annual Meeting”) or until her successor has been duly elected and qualified.

Ms. Parsons will receive the same compensation and benefits as the other non-employee directors on the Board, consistent with the Company’s non-employee director compensation program described in the Definitive Proxy Statement on Schedule 14A (at Pages 84 to 86) that the Company filed with the Securities and Exchange Commission on March 26, 2025. However, Ms. Parsons will not receive an annual equity award for fiscal year 2025, as the Company’s 2025 Annual Meeting of Stockholders, at which time the annual equity awards were granted, was already held. Ms. Parsons’ annual cash retainer for fiscal year 2025 will be prorated for the period from the Appointment through December 31, 2025.

No arrangements or understandings exist between Ms. Parsons or any other persons by which she was named a director of the Company. Ms. Parsons has no family relationships with any Company director or executive officer, and the Company has not entered into any transactions with Ms. Sampson reportable per Item 404(a) of Regulation S-K.
