Rule 10b5-1 Plan Trading Arrangements

During the three months ended September 30, 2025, the following officers adopted a “Rule 10b5-1 trading arrangement” (as defined in Item 408 of Regulation S-K) that is intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act and our policies on insider trading:

(1)

The Rule 10b5-1 trading arrangement permits transactions through and including the earlier to occur of (a) the completion of all sales or (b) the date listed in the table. The arrangement also provides for automatic expiration in the event of liquidation, dissolution, bankruptcy, insolvency, or death of the adopting person.

(2)

The Rule 10b5-1 trading arrangement includes the sale of up to 59,233 shares to be received upon future vesting of certain outstanding equity awards, net of any shares withheld by us to satisfy applicable taxes. The number of shares to be withheld, and thus the exact number of shares to be sold pursuant to Mr. Quinn’s Rule 10b5-1 trading arrangement, can only be determined upon the occurrence of the future vesting events. For purposes of this disclosure, we have reported the gross number of shares to be received upon the future vesting of such equity awards, before subtracting any shares to be withheld by us to satisfy applicable taxes in connection with such future vesting events. Furthermore, the Rule 10b5-1 trading arrangement provides for the sale of 50% of the net shares that vest on the applicable vesting date. The 10b5-1 trading arrangement also provides for the sale of up to 4,667 shares directly held by Mr. Quinn such that the gross proceeds from their sale is sufficient to raise $25,000 for purposes of a gift to a charitable donor-advised fund.

Other than those disclosed above, none of our directors or officers adopted, modified, orterminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” in each case as defined in Item 408 of Regulation S-K.
