During the three months ended September 30, 2025, certain of our officers and directors adopted Rule 10b5-1 trading arrangements as follows.

On August 11, 2025, Renee M. Bacon, Senior Vice President, Sales and Operations & Chief Merchandising Officer, adopted a trading plan intended to satisfy the conditions under Rule 10b5-1(c) of the Exchange Act. Ms. Bacon's plan is for the sale of 606 RSUs and 1,212 PSUs that she will receive at the February 2026 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, and may vary from the approximate number provided. The plan will terminate at the earlier of the date all shares under the plan are sold or February 27, 2026.

On August 12, 2025, Mindy K. West, currently President and Chief Operating Officer, adopted a trading plan intended to satisfy the conditions under Rule 10b5-1(c) of the Exchange Act. Ms. West's plan is for the exercise of 17,200 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 and may vary from the approximate number provided. The plan will terminate at the earlier of the date all shares under the plan are sold or May 29, 2026.
