Filing footnotes — Forward sale contract (obligation to sell) (Direct)
On September 28, 2026, V3 Holding Limited ("V3") settled the first of three tranches of a variable prepaid forward sale contract (the "Forward Contract") that was entered into on November 3, 2025 with an unaffiliated third-party dealer (the "Dealer"). The Forward Contract obligates V3 to deliver to the Dealer up to 1,805,000 shares of Common Stock in each of three tranches within one business day after each of the three maturity dates of the Forward Contract (September 25, 2026, October 23, 2026 and November 30, 2026), for an aggregate amount of up to 5,415,000 shares. In exchange for assuming this obligation, V3 received a cash payment of $100.0 million as of the date of entering into the Forward Contract. V3 pledged 5,415,000 shares of Common Stock (the "Pledged Shares") to secure its obligations under the Forward Contract. [Continued] [Cont.] The number of shares of Common Stock to be delivered to the Dealer on each of the three maturity dates are determined as follows: (a) if the volume-weighted average price of Common Stock during the trading day immediately preceding the maturity date (the "Settlement Price") is less than or equal to $21.4881 (the "Floor Price"), the reporting person will deliver to the Dealer 1,805,000 shares; (b) if the Settlement Price is between the Floor Price and $32.2322 (the "Cap Price"), the reporting person will deliver to the Dealer a number of shares of Common Stock having a value (based on the then market price) equal to $38.8 million; and (c) if the Settlement Price is greater than the Cap Price, the reporting person will deliver to the Dealer a number of shares of Common Stock equal to 1,805,000 shares minus a number of shares of Common Stock having a value (based on the then market price) equal to $19.4 million. [Continued] [Cont.] V3 retained economic and voting rights in the Pledged Shares during the term of the pledge. On September 25, 2026, the Settlement Price was $17.83. Accordingly, V3 transferred to the Dealer 1,805,000 shares. |
