(the "Broker"). Pursuant to the 10b5-1 Plan, the Broker may sell up to 15,782,660 Ordinary Shares on behalf of the Reporting Person, starting on the later of (i) September 11, 2026 or (ii) the expiration of the applicable "cooling off" period under Rule 10b5-1(c)(1)(ii)(B)(1) under the Act, provided that, certain Ordinary Shares are also subject to the Lock-Up Agreement, as described further in the third paragraph to this Item 4. The 10b5-1 Plan will terminate on the earlier of (i) December 31, 2027, (ii) the date on which all 15,782,660 Ordinary Shares have been sold under the 10b5-1 Plan, and (iii) the date the 10b5-1 Plan is otherwise terminated pursuant to its terms. Pursuant to the terms of the 10b5-1 Plan, the European-style call options described in the Initial Schedule 13D will automatically be exercised at their Maturity Date and the underlying Ordinary Shares acquired thereby may be sold over the subsequent days. In addition, pursuant to the terms of the 10b5-1 Plan, once the lock-up period under the Lock-Up Agreement expires on October 1, 2026, and through the expiration of the 10b5-1 Plan on December 31, 2027, (i) an additional 1.5 million shares may be sold in monthly tranches of 100,000 shares, and (ii) an additional 11 million shares may be sold, in tranches of 1 million shares at limit prices between $10 and $20, inclusive. The 21,610,244 Ordinary Shares beneficially owned by the Reporting Person as of the date hereof are subject to the Lock-Up Agreement described in Item 6 of the Initial Schedule 13D and, accordingly, none of these shares may be sold prior to the expiration of the lock-up period; any Ordinary Shares acquired by the Reporting Person upon automatic exercise of the European-style call options pursuant to the terms of the 10b5-1 Plan are not subject to the Lock-Up Agreement and thus may be sold prior to the expiration of the Lock-Up period. The Reporting Person entered into the 10b5-1 Plan for financial planning purposes.
