Item 5. Other Information.

(c) Insider Trading Arrangements

During the second quarter 2026, Lori Niederst, our Chief Personal Lines Officer, entered into a Rule 10b5-1 trading arrangement that is intended to satisfy the affirmative defense of Rule 10b5-1(c). The plan provides for the sale of all of the shares issued upon vesting for certain outstanding equity awards previously granted to Ms. Niederst, excluding any shares withheld by the company to satisfy tax withholding obligations (see our 2026 Proxy Statement for a description of the company’s equity compensation plans). The plan was entered into on April 16, 2026, and will expire on February 12, 2027, subject to the plan’s earlier expiration or completion in accordance with its terms.
