Explanation of responses 3 footnotes

Footnote F1

On August 20, 2026, the reporting person exercised 27,575 vested synthetic options for cash settlement pursuant to the Issuer's Synthetic Option Scheme. The cash settlement value was determined based on the closing price of the Issuer's ordinary shares on the New York Stock Exchange on August 19, 2026 of $32.48 per share less the strike price of $20.75 per synthetic share option, which reflects adjustments made pursuant to the Issuer's Synthetic Option Scheme, including adjustments for dividends. No ordinary shares were issued upon exercise.

Footnote F2

The reported exercise relates to the first tranche of synthetic options granted on June 24, 2025 under the Issuer's Synthetic Option Scheme. This tranche consisted of 27,575 synthetic options, all of which vested on June 24, 2026 and became exercisable upon vesting. The synthetic options issued pursuant to the Issuer's Synthetic Option Scheme vest over a three-year period in increments of one-third per annum with initial vesting on June 24, 2026 and subsequent vesting on June 24, 2027 and June 24, 2028.

Footnote F3

The reported securities are cash-settled synthetic options granted under the Issuer's Synthetic Option Scheme and do not represent a right to acquire ordinary shares of the Issuer.
