Explanation of Responses:
1. Includes 7,820 shares of common stock of the Registrant acquired in exchange for ordinary shares of Ashtead Group plc ("Ashtead") beneficially owned by the Reporting Person, upon completion of the scheme of arrangement effected by Ashtead, the Registrant's predecessor, under Part 26 of the UK Companies Act 2006. The exchange ratio was one-to-one and no cash consideration was paid or received.
2. Includes 9,002 restricted stock units, of which 1,632 will vest on June 20, 2026; 1,913 will vest on July 4, 2026; 1,632 will vest on June 20, 2027; 1,913 will vest on July 4, 2027; and 1,912 will vest on July 4, 2028. Each restricted stock unit represents a contractual right to receive one share of common stock of the Registrant.
3. This Form 4 amendment is being filed to correct the inadvertent omission in the original report of 7,820 shares of Sunbelt common stock acquired by the Reporting Person in exchange for ordinary shares of Ashtead previously held in a vested share account with registrar and transfer agent. The Reporting Person's total beneficial ownership following the reported transaction in Column 5 of Table I has been adjusted to reflect these additional shares. As of the filing of this amendment, the Reporting Person directly beneficially owns 46,799 shares of common stock.
