Explanation of Responses:

( 1 )The reported transaction involved the reporting person's receipt of a grant of 7,320 restricted stock units ("RSUs") under the Hamilton Insurance Group, Ltd. ("HG") Equity Incentive Plan which vest one third per year on March 1, 2026, 2027 and 2028 respectively. Each RSU represents a contingent right to receive one share of HG Class B Common Shares upon vesting. On February 28, 2025, the reporting person filed a Form 4 which incorrectly stated the number of RSUs and common shares owned. This amendment on Form 4/A is being filed to correct the total number of shares reported in Column 5. The corrected total reported in Column 5 includes the 7,320 newly awarded and unvested RSUs, 37,501 unvested RSUs previously reported in Table I and Table II and 32,152 Common Shares. ( 2 )Represents shares acquired upon the certification by HG for the satisfaction of performance criteria underlying an award of performance stock units ("PSUs") previously granted to the reporting person under the terms of the HG Equity Incentive Plan. The reporting person's PSUs are earned based on the HG annualized underwriting return on capital for the 3-year performance period ending on December 31, 2024. HG confirmed the annualized underwriting return on capital for the 3-year performance period ending on December 31, 2024, was 6.1%, resulting in a performance payout at 146.4% of target. ( 3 )Represents shares withheld to satisfy tax obligations arising out of the vesting of the Reporting Person's PSUs. ( 4 )Represents the value of the shares used to determine the number of shares to be retained by the issuer to satisfy the tax withholding obligations.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
