(c)Insider Trading Arrangements

During the third quarter 2024, certain executive officers and a director entered into Rule 10b5-1 trading arrangements that are intended to satisfy the affirmative defense of Rule 10b5-1(c). The executive officers’ plans provide for: i) the sale of all of the shares upon vesting pursuant to certain outstanding equity awards previously granted to the applicable executive officer, excluding any shares withheld by the company to satisfy tax withholding obligations (see the 2024 Proxy Statement for a description of the company’s equity compensation plans) and, ii) for one executive, the sale of a certain amount of additional 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 in i) above), some of which may have been the result of a prior vesting event for the executive. The director’s plan provides for the sale of a specified amount of shares held by the director, some of which may have been the result of a prior vesting event.

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