As contemplated in the Merger Agreement, the Mergers resulted in the following treatment of the Company’s equity awards:

Company Restricted Shares: At the First Effective Time, each awarded Ordinary Share subject solely to service-based vesting requirements (each, a “Company Restricted Share”), whether vested or unvested, was deemed to be fully vested and non-forfeitable and was converted into the right to receive the First Merger Consideration.

Company RSUs: At the First Effective Time, each restricted share unit award in respect of Ordinary Shares subject solely to service-based vesting requirements (each, a “Company RSU Award”), was deemed to pertain to a restricted share unit award in respect of a number of New Ordinary Shares equal to (1) the number of Ordinary Shares subject to such Company RSU Award multiplied by (2) the First Merger Ratio and otherwise subject to the same terms and conditions. At the Second Effective Time, each such Company RSU Award was deemed to pertain to a restricted share unit award in respect of Second Surviving Company Ordinary Shares subject to the same terms and conditions. At the Third Effective Time, each such Company RSU Award whether vested or unvested, was deemed to be fully vested and non-forfeitable and was canceled and converted into the right to receive a cash payment equal to (A) the Third Merger Cash Consideration, multiplied by (B) the total number of Second Surviving Company Ordinary Shares subject to such Company RSU Award immediately prior to the Third Effective Time, plus (C) an amount equal to the First Merger Cash Consideration multiplied by the total number of Ordinary Shares subject to such Company RSU Award as of immediately prior to the First Effective Time.

Company PSUs: At the First Effective Time, each restricted share unit award in respect of Ordinary Shares subject to performance-based vesting requirements (each, a “Company PSU Award”) was deemed to pertain to a restricted share unit award in respect of a number of New Ordinary Shares equal to (1) the number of Ordinary Shares subject to such Company PSU Award multiplied by (2) the First Merger Ratio and otherwise subject to the same terms and conditions. At the Second Effective Time, each such Company PSU Award was deemed to pertain to a restricted share unit award in respect of Second Surviving Company Ordinary Shares subject to the same terms and conditions. At the Third Effective Time, a portion of each such Company PSU Award vested at actual performance on a prorated basis, based on the portion of the performance period lapsed through the Third Effective Time, and was canceled and converted into the right to receive a cash payment equal to (A) the Third Merger Cash Consideration, multiplied by (B) the vested portion of such Company PSU Award, plus (C) an amount equal to the First Merger Cash Consideration multiplied by the total number of Ordinary Shares subject to the vested portion of such Company PSU Award immediately prior to the First Effective Time, and the remaining unvested portion of such Company PSU Award was canceled and forfeited.

The foregoing description does not purport to be complete and is subject to and qualified in its entirety by reference to the full text of the Merger Agreement, which is included as Exhibit 2.1 to the Company’s Current Report on Form 8-K filed with the SEC on July 29, 2024, and is incorporated herein by reference.

On July 2, 2025, the Company also notified representatives of Nasdaq of its determination to voluntarily withdraw its depositary shares, each representing a 1/1,000th interest in a 7.00% Fixed-to-Floating Rate Perpetual Non-Cumulative Preferred Share, Series D, par value $1.00 per share, and its depositary shares, each representing a 7.00% Perpetual Non-Cumulative Preferred Share, Series E, par value $1.00 per share (collectively, the “Depositary Shares”) from listing on Nasdaq and registration pursuant to Section 12(b) of the Exchange Act, and its intention to file a Form 25 Notification of Delisting with the SEC (the “Depositary Shares Form 25” and together with the Ordinary Shares Form 25, the “Form 25s”) on or about July 14, 2025 relating to delisting and deregistering of the Depositary Shares.

Following the effectiveness of the Form 25s, the Company intends to file with the SEC a certification on Form 15 requesting the termination of registration of Enstar Ordinary Shares and the Depositary Shares under Section 12(g) of the Exchange Act and the suspension of reporting obligations under Sections 13 and 15(d) of the Exchange Act. Such deregistration of the Enstar Ordinary Shares and the Depositary Shares will become effective 90 days after the filing of the applicable Form 25 or such shorter period as may be determined by the SEC.
