Explanatory Note

This Amendment No. 3 to Schedule 13D (this “Amendment No. ”) relates to the common shares (the “Common Shares”) of SiriusPoint Ltd., a Bermuda exempted company limited by shares (the “Issuer” or the “Company”), and amends the Schedule 13D filed by the undersigned reporting person (the “Reporting Person”) on August 2, 2021, as amended by the Amendment No. 1 to Schedule 13D filed by the Reporting Person on May 17, 2022 and as further amended by the Amendment No. 2 to the Schedule 13D filed by the Reporting Person on April 12, 2023 (as so amended, the “Original Schedule 13D” and, together with this Amendment No. 3, the “Schedule 13D”). Capitalized terms used and not defined in this Amendment No. 3 have the meanings set forth in the Original Schedule 13D.

This Amendment No. 3 is being filed to amend Item 4 and Item 5 as follows:

Item 4 of the Original Schedule 13D is hereby amended and supplemented to include the following:

The Reporting Person and his affiliates have, as previously disclosed, explored a potential acquisition of all or substantially all of the outstanding Common Shares of the Issuer (an “Acquisition Transaction”). Although the Issuer and the Reporting Person, through their respective advisors, have had exploratory discussions, they have been unable to reach consensus on the value of a potential transaction. Accordingly, the Reporting Person is no longer exploring an Acquisition Transaction. The Reporting Person is grateful to the Special Committee of the Board of the Issuer, and its advisors, for engaging in discussions on these matters.

As previously disclosed, the Reporting Person has total confidence that the Issuer’s management team, led by its Chief Executive Officer, is undertaking the necessary steps to position the Issuer for long-term success by strengthening its balance sheet and enhancing its credit ratings. In particular, the Reporting Person is fully supportive of the management team’s formulation and application of a fixed income and hedging program that should provide above-industry average investment returns, without taking on excess risk, while adhering to the highest regulatory standards.

Other than as set forth in this Schedule 13D, the Reporting Person does not have any present plans or proposals that relate to, or that would result in, any of the events described in paragraphs (a) to (j) of the instructions to Item 4 of Schedule 13D. The Reporting Person will, however, continue to review the investment in the Issuer and, depending upon market conditions and other factors that the Reporting Person deems material, the Reporting Person reserves the right to formulate plans or make proposals, and to take any actions with respect to the investment in the Issuer, including any or all of the actions described in paragraphs (a) to (j) of the instructions to Item 4 of Schedule 13D.

Item 5 of the Original Schedule 13D is hereby amended and restated to read as follows:

(a) On the date of this Schedule 13D, the Reporting Person may be deemed to beneficially own, in the aggregate, approximately 9.31% of the Common Shares outstanding, of which the 2010 Loeb Family Trust owns 235,127 Common Shares, Third Point Advisors LLC owns 1,000,000 Common Shares, Third Point Opportunities Master Fund L.P. owns 7,493,842 Common Shares, the 2011 Loeb Family GST Trust owns 4,903,795 Common Shares and the Reporting Person owns the balance of the Common Shares reported herein. The Reporting Person disclaims beneficial ownership of such Common Shares except to the extent of his pecuniary interest therein, if any. The calculation of the percentage of Common Shares beneficially owned by the Reporting Person is based on the 162,954,629 Common Shares outstanding as of April 28, 2023, as reported by the Issuer in its Annual Report on Form 10-Q which was filed with the SEC on May 3, 2023.

(b) The Reporting Person has sole voting and dispositive power over the Common Shares set forth in Item 5(a) above.

(c) The Reporting Person has not effected any transaction in the past 60 days in Common Shares.

(d) Other than the affiliates of the Reporting Person set forth in Item 5(a) of this Schedule 13D, no other person has the right to receive, or the power to direct the receipt of, dividends from or proceeds from the sale, of the Common Shares described in this Schedule 13D.

(e) Not applicable.
