(c)Insider Trading Arrangements and Policies

Rule 10b5-1 Plans

Ruth T. Dowling, our Executive Vice President, Chief Administrative Officer, General Counsel and Secretary, entered into a pre-arranged stock trading plan on October 29, 2025. Ms. Dowling’s plan provides for the potential sale of up to 5,679 shares of our common stock between February 27, 2026 and November 2, 2026.

This trading plan was entered into during an open insider trading window and is intended to satisfy the affirmative defense of Rule 10b5-1 under the Exchange Act and our policies regarding transactions in our securities. Generally, this trading plan pre-establishes the amounts, prices and dates of future purchases or sales of our stock, including shares issued upon the exercise or vesting of equity awards. Under this trading plan, the individual officer relinquishes control over the transactions once the trading plan is put into place. Accordingly, sales under this plan may occur at any time, including possibly before, simultaneously with, or immediately after, significant company events.
