(c) Insider Trading Arrangements

During the first quarter 2026, certain executive officers entered into Rule 10b5-1 trading arrangements that are intended to satisfy the affirmative defense of Rule 10b5-1(c). The trading arrangements provide for: (i) the sale of all (or a certain percentage) of the shares issued upon vesting for certain outstanding equity awards previously granted to the applicable executive, 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) and (ii) the sale and/or gift of a certain amount of shares (see “Additional or Specified Shares” below) held by the applicable executive, that are not sold in connection with the vesting of an outstanding equity award (as described above), some of which may have been the result of a prior vesting event for the applicable executive.

Below are the details of each applicable Rule 10b5-1 trading arrangement:
