Section 1 – Registrant’s Business and Operations

Item 1.01. Entry into a Material Definitive Agreement.

On June 30, 2025, Selective Insurance Group, Inc. (“Selective”) entered into that certain Credit Agreement (the “Agreement”), by and among Selective, the lenders named therein (collectively, the “Lenders”), and Wells Fargo Bank, National Association, as administrative agent (the “Administrative Agent”). Under the Agreement, the Lenders have agreed to provide Selective with a $100 million revolving credit facility, which can be increased to $200 million with the consent of the Lenders. The Agreement will mature on June 30, 2028.

Interest rates on borrowings under the credit facility are indexed to either a base rate or the term Secured Overnight Financing Rate (SOFR) for one-, three-, or six-month interest periods, as selected by Selective at the time of borrowing, plus a specified margin dependent on Selective’s debt rating.

The Agreement contains representations, warranties, and covenants that are customary for credit facilities of this type, including, without limitation, financial covenants under which Selective is obligated to maintain a minimum consolidated net worth and maximum ratio of consolidated debt to total capitalization, and covenants limiting the ability of Selective to: (i) merge or liquidate; (ii) incur debt or liens; (iii) dispose of assets; (iv) make investments and acquisitions; and (v) engage in transactions with affiliates.

The Agreement also contains customary events of default, including, without limitation: (i) failure to pay principal, interest, or fees when due; (ii) covenant default; (iii) material breach of representations or warranties; (iv) cross-default to other debt in excess of an agreed amount; (v) insolvency or bankruptcy; (vi) monetary judgment in excess of an agreed amount; and (vii) a change in control event. If an event of default under the Agreement occurs and is continuing, then the Administrative Agent, at the direction, or with the consent, of the Requisite Lenders (as defined in the Agreement), may declare outstanding obligations under the Agreement immediately due and payable.

The foregoing description of the Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Agreement, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

Item 1.02. Termination of a Material Definitive Agreement.

Selective was a party to that certain Credit Agreement (the “Prior Credit Agreement”), by and among Selective, the lenders named therein (collectively, the “Prior Credit Agreement Lenders”), and the Administrative Agent, dated November 7, 2022, pursuant to which the Prior Credit Agreement Lenders agreed to provide Selective with a $50 million revolving credit facility, which could be increased to $125 million with the consent of the Prior Credit Agreement Lenders. The Prior Credit Agreement was scheduled to mature on November 7, 2025.

Pursuant to Section 10.19 of the Agreement, upon the effectiveness of the Agreement pursuant to Section 3.1 and the payment in full of all indebtedness, liabilities, and obligations under the Prior Credit Agreement (other than obligations which, by their express terms, survive the termination thereof), the Prior Credit Agreement automatically terminated. The termination of the Prior Credit Agreement did not result in any penalties to Selective.

The foregoing description of the Prior Credit Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Prior Credit Agreement, which is filed as Exhibit 10.1 to Selective’s Current Report on Form 8-K filed on November 8, 2022 and is incorporated herein by reference.
