[1] Amount represents the acquisition cost of all common shares acquired and subsequently retired during the three months ended June 30, 2026. Specifically, the Company (1) repurchased 4,725,968 of its Class A common shares at an average price of $14.07 per share, for $66.4 million and (2) withheld common shares otherwise issuable to satisfy employee tax withholding obligations associated with employee incentive plans for $2.4 million, all of which were retired in the same period. The shares withheld are accounted for as a repurchase of common shares. As the par value of such shares were negligible and there was an accumulated deficit, the entire acquisition cost was deducted from additional paid in capital.
