Rule 10b5-1 Plan Trading Arrangements

During the three months ended September 30, 2026, 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 conditions 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 24,343 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 Ms. Hanson’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.

On March 2, 2026, Javier Zamora, our then General Counsel and Corporate Secretary, adopted a “Rule 10b5-1 trading arrangement” that was intended to satisfy the affirmative defense of Rule 10b5-1(c) under the Exchange Act and our policies on insider trading, or the Zamora Plan. Pursuant to the Zamora Plan, up to 54,453 shares of our Class A common stock were to be sold, including shares obtained from the vesting of restricted stock units (subject to reduction for any shares withheld to satisfy tax withholding obligations), and had an expiration date of February 16, 2027. On September 28, 2026, Mr. Zamora terminated the Zamora Plan.

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.
