Explanation of Responses:

1. AI Securities Holdings 1 LLC ("AISH"), an affiliate of Access Industries, LLC that is indirectly controlled by Len Blavatnik, is party to a cash-settled European-style capped-call agreement (the "Capped-Call Agreement") with an unaffiliated third party financial institution, the final terms of which were set on June 13, 2025. The Capped-Call Agreement provides AISH with economic results that are comparable to ownership of a call option in respect of 8,122,120 ordinary shares, at a per share premium of $4.4196, with a strike price $79.9887 per share and cap price of $122.6493 per share (such amounts, subject to adjustments in certain circumstances, including dividends paid by the Issuer).

2. The Capped-Call Agreement is exercisable in 30 separate tranches of 270,737 shares each (other than the first tranche, of 270,747 shares), with staggered expirations in successive days, beginning June 7, 2030. As settlement of the Capped-Call Agreement is in cash only, neither AISH, nor any of the Reporting Persons, nor any of their affiliated entities and the officers, partners, members, and managers thereof, shall be deemed to beneficially own the ordinary shares referenced thereunder.
