On February 23, 2026, Renee M. Bacon, Senior Vice President, Chief Retail Officer, adopted a trading plan intended to satisfy the conditions under Rule 10b5-1(c) of the Exchange Act. Ms. Bacon's plan provides for the aggregate of (i) the exercise of 2,600 vested options and the sale of the resulting net shares, the actual number of shares sold will depend on the number of shares withheld by the Company to satisfy the option exercise price and income tax withholding obligations, (ii) the sale of 454 shares upon the vesting of certain RSUs and (iii) the sale of 908 shares upon the vesting of certain PSUs, each of which she will receive at the February 2027 vesting date, the actual number of shares sold will depend on the vesting of certain performance-based equity awards and the number of shares withheld by the Company to satisfy its income tax withholding obligations. The plan will terminate at the earlier of the date all shares under the plan are sold or February 26, 2027.
