F1 · derivative.exercise_price: On 30 March, 2026, IWAY LLC ("IWAY") entered into a prepaid variable forward transaction (aka "collar financing") with an unaffiliated third party buyer. The transaction obligates IWAY to deliver to the buyer up to 2,500,000 aggregate shares of the Issuer's Class A Ordinary Shares (or at IWAY's election, an equivalent amount of cash) on specified dates in 2029. In exchange for assuming this obligation, IWAY received an aggregate cash payment. IWAY has granted security over 2,500,000 Class B ordinary shares of the Issuer (the "Charged Class B Shares") to secure its obligations under the transaction, and retained dividend and voting rights in the Charged Class B Shares during the term of the transaction but may be required to make cash payments upon the occurrence of certain dividends declared prior to settlement.

F2 · derivative.exercise_price: This transaction is divided into 25 individual components (each comprising 100,000 shares) (the "Component Shares") of Class A ordinary shares). The number of Class A ordinary shares to be delivered to the buyer with respect to each component at settlement will be based on the volume weighted average price per share of the Class A ordinary shares on the Stock Exchange of Hong Kong Limited for each day during the valuation period (the "Settlement Price") as follows: (A) if the Settlement Price for any component is less than a floor price that is based on the price at which the buyer established its initial hedge position during the initial hedging period (the "Floor Price"), IWAY will deliver for that component the Component Shares; (B) if the Settlement Price for any component is less than or equal to a cap price that is based on the price at which the buyer established its initial hedge position during the initial hedging period (the "Cap Price"),

F3 · derivative.exercise_price: (continued from Footnote 2) but greater than the Floor Price, IWAY will deliver for that component a number of Class A ordinary shares equal to (i) the Component Shares, multiplied by a fraction, the numerator of which is the Floor Price and the denominator of which is the Settlement Price; and (C) if the Settlement Price for any component is greater than the Cap Price, IWAY will deliver for that component a number of shares equal to (i) the Component Shares, multiplied by (ii) a fraction, the numerator of which is the sum of (x) the Floor Price and (y) the Settlement Price minus the Cap Price, and the denominator of which is the Settlement Price, in each case rounded up to the nearest whole share.

IWAY has granted security over 2,500,000 Class B ordinary shares of the Issuer (the "Charged Class B Shares") to secure its obligations under the transaction, and retained dividend and voting rights in the Charged Class B Shares during the term of the transaction but may be required to make cash payments upon the occurrence of certain dividends declared prior to settlement.
