Scott Egan, Chief Executive Officer, said: “It has been another strong quarter of delivery for SiriusPoint, marking our eighth consecutive quarter of positive underwriting income. We have delivered a 4.0 point improvement in the combined ratio to 88.5% whilst growing continuing lines premium by 10% during the quarter. Our focus is resolute on building a strong business driven by disciplined underwriting to create a balanced portfolio that creates shareholder value.

Our strategic partnerships are a powerful tool to help us deliver our growth and underwriting ambitions. We added six new distribution partnerships in the quarter through our MGA Centre of Excellence, which is earning a reputation in the market as an attractive and leading platform for program administrators and MGAs. Fee income from our two consolidated A&H MGAs grew 18% year to date. Net investment income was strong, at $78m for the quarter, and our FY 24 net investment income is now trending ahead of our previous guidance.

We completed on an important two-part strategic transaction with CMIG in the quarter, deploying capital for the purchase and retirement of $125m of common shares and the settlement of Series A Preference Shares, both for cash. Our Q3 BSCR estimate of 265% demonstrates the strength of our balance sheet, and our annualized year to date underlying ROE of 14.4%, which excludes one-off actions, is in line with our medium-term guidance of 12-15% and demonstrates the strength of our earnings.

This quarter marks my second full year at SiriusPoint, and I am incredibly proud of the scale and pace of transformation we have achieved so far. This company is and always will be about our people and I am incredibly grateful to them for their relentless dedication and determination to make the company better. Together, we will drive further value through strategic, targeted improvement as we build a sustainable, best-in-class business for the future.”

Third Quarter 2024 Summary

Consolidated underwriting income for the three months ended September 30, 2024 was $89.0 million compared to $73.8 million for the three months ended September 30, 2023. The improvement was primarily driven by increased favorable prior year loss reserve development and a more favorable commission ratio. For the three months ended September 30, 2024, favorable prior year loss reserve development was $30.6 million from favorable development in Property, mainly driven by reserve releases relating to favorable COVID-19 development trends, as well as favorable development in Accident and Health (“A&H”) due to lower than expected reported attritional losses, compared to $24.7 million for the three months ended September 30, 2023 driven by reserving analyses performed in connection with the March 2, 2023 loss portfolio transfer transaction (“2023 LPT”).

Consolidated underwriting income for the nine months ended September 30, 2024 was $243.7 million compared to $339.2 million for the nine months ended September 30, 2023. The decrease was primarily driven by lower favorable prior year loss reserve development. Favorable prior year loss reserve development for the nine months ended September 30, 2023 included $122.2 million driven by reserving analyses performed in connection with the 2023 LPT. Excluding the favorable development linked to the 2023 LPT, underwriting income increased by $19.8 million primarily resulting from favorable development in Property, mainly driven by reserve releases relating to favorable COVID-19 development trends, as well as favorable development in A&H and our runoff business, due to lower than expected reported attritional losses. This increase was partially offset by higher acquisition costs from business mix changes, including the growth of Insurance & Services.

The determination of our reportable segments is based on the manner in which management monitors the performance of our operations, which consist of two reportable segments - Reinsurance and Insurance & Services.

Collectively, the sum of our two segments, Reinsurance and Insurance & Services, constitute our “Core” results. Core underwriting income, Core net services income, Core income and Core combined ratio are non-GAAP financial measures. See reconciliations in “Segment Reporting”. We believe it is useful to review Core results as it better reflects how management views the business and reflects our decision to exit the runoff business. The sum of Core results and Corporate results are equal to the consolidated results of operations.

Gross premiums written decreased by $35.0 million, or 4.8%, to $690.5 million for the three months ended September 30, 2024 compared to $725.5 million for the three months ended September 30, 2023. Net premiums earned decreased by $29.0 million, or 5.0%, to $546.3 million for the three months ended September 30, 2024 compared to $575.3 million for the three months ended September 30, 2023. The decreases in premiums written were primarily driven by the movement of certain lines from Insurance & Services to Corporate, including the non-renewal of a Workers’ Compensation program and the planned transition of a Cyber program to another carrier.

These decreases were partially offset by increases in Reinsurance from Property and International Specialty and increases from Insurance & Services from strategic organic and new program growth.

Gross premiums written decreased by $177.0 million, or 6.8%, to $2,413.9 million for the nine months ended September 30, 2024 compared to $2,590.9 million for the nine months ended September 30, 2023. Net premiums earned decreased by $104.7 million, or 6.1%, to $1,617.5 million for the nine months ended September 30, 2024 compared to $1,722.2 million for the nine months ended September 30, 2023. The decreases in premium volume were primarily due to the movement of certain lines from Insurance & Services to Corporate, including the non-renewal of a Workers’ Compensation program and the planned transition of a Cyber program to another carrier, with the most significant offset being strategic organic and new program growth within Insurance & Services.

Core results for the three months ended September 30, 2024 included income of $69.5 million compared to $50.0 million for the three months ended September 30, 2023. Income for the three months ended September 30, 2024 consists of underwriting income of $62.5 million (88.5% combined ratio) and net services income of $7.0 million, compared to underwriting income of $42.5 million (92.5% combined ratio) and net services income of $7.5 million for the three months ended September 30, 2023. The improvement in net underwriting results was primarily driven by favorable prior year loss reserve development and a more favorable commission ratio, partially offset by higher catastrophe losses.

Losses incurred included $29.7 million of favorable prior year loss reserve development for the three months ended September 30, 2024 primarily resulting from favorable development in Property, mainly driven by reserve releases relating to favorable COVID-19 development trends, as well as favorable development in A&H due to lower than expected reported attritional losses, compared to $12.6 million for the three months ended September 30, 2023 driven by reserving analyses performed in connection with the 2023 LPT.

Catastrophe losses, net of reinsurance and reinstatement premiums, for the three months ended September 30, 2024, were $10.6 million, or 1.9 percentage points on the combined ratio, including $10.0 million from Hurricane Helene, compared to $6.7 million, or 1.2 percentage points on the combined ratio, for the three months ended September 30, 2023, which includes losses of $3.8 million from the Hawaii wildfires and $3.3 million from Hurricane Idalia.

Core results for the nine months ended September 30, 2024 included income of $177.9 million compared to $245.1 million for the nine months ended September 30, 2023.

The decrease in net underwriting results was primarily driven by lower favorable prior year loss reserve development. Favorable prior year loss reserve development for the nine months ended September 30, 2023 included $102.4 million driven by reserving analyses performed in connection with the 2023 LPT.

Excluding the favorable development linked to the 2023 LPT, net underwriting income increased by $27.7 million primarily driven by favorable development in Property, mainly driven by reserve releases relating to favorable COVID-19 development trends, as well as favorable development in A&H due to lower than expected reported attritional losses, partially offset by higher acquisition costs from business mix changes, including the growth of Insurance & Services.

Reinsurance gross premiums written were $314.5 million for the three months ended September 30, 2024, an increase of $49.1 million, or 18.5%, compared to the three months ended September 30, 2023, primarily driven by increases in Bermuda and New York Property and International Specialty, partially offset by lower premiums written in New York Casualty.

Reinsurance generated underwriting income of $41.6 million (84.6% combined ratio) for the three months ended September 30, 2024, compared to underwriting income of $36.9 million (85.6% combined ratio) for the three months ended September 30, 2023. The increase in net underwriting results was primarily driven by lower attritional losses and favorable commission ratio, partially offset by higher catastrophe losses.

Reinsurance gross premiums written were $1,023.4 million for the nine months ended September 30, 2024, an increase of $4.1 million, or 0.4%, compared to the nine months ended September 30, 2023, primarily driven by increases in International Specialty, partially offset by lower premiums written in New York Casualty and Bermuda Specialty.

Reinsurance generated underwriting income of $106.5 million (86.3% combined ratio) for the nine months ended September 30, 2024, compared to underwriting income of $178.4 million (77.4% combined ratio) for the nine months ended September 30, 2023. The decrease in net underwriting results was primarily due to decreased favorable prior year loss reserve development as the nine months ended September 30, 2023 included $90.6 million driven by reserving analyses performed in connection with the 2023 LPT. Net favorable prior year loss reserve development was $33.2 million for the nine months ended September 30, 2024 primarily driven by favorable development in Property, mainly driven by reserve releases relating to favorable COVID-19 development trends.

Insurance & Services gross premiums written were $376.0 million for the three months ended September 30, 2024, a decrease of $84.1 million, or 18.3%, compared to the three months ended September 30, 2023, primarily driven by the movement of certain lines from Insurance & Services to Corporate, including the non-renewal of a Workers’ Compensation program and the planned transition of a Cyber program to another carrier, representing $98.0 million of gross premiums written for the three months ended September 30, 2023, as well as lower A&H premiums, partially offset by strategic organic and new program growth.

Insurance & Services generated segment income of $27.9 million for the three months ended September 30, 2024, compared to income of $13.3 million for the three months ended September 30, 2023. Segment income for the three months ended September 30, 2024 consists of underwriting income of $20.9 million (92.4% combined ratio) and net services income of $7.0 million, compared to underwriting income of $5.6 million (98.3% combined ratio) and net services income of $7.7 million for the three months ended September 30, 2023. The improvement in underwriting results was primarily driven by net favorable prior year loss reserve development of $13.1 million for the three months ended September 30, 2024, mainly in A&H due to lower than expected reported attritional losses, compared to net adverse prior year loss reserve development of $6.6 million for the three months ended September 30, 2023, mainly in Workers’ Compensation.

Insurance & Services gross premiums written were $1,390.5 million for the nine months ended September 30, 2024, a decrease of $181.1 million, or 11.5%, compared to the nine months ended September 30, 2023, primarily driven by the movement of certain lines from Insurance & Services to Corporate, including the non-renewal of a Workers’ Compensation program and the planned transition of a Cyber program to another carrier, representing $331.8 million of gross premiums written for the nine months ended September 30, 2023, as well as lower A&H premiums, partially offset by strategic organic and new program growth.

Insurance & Services generated segment income of $71.4 million for the nine months ended September 30, 2024, compared to income of $69.5 million for the nine months ended September 30, 2023. Segment income for the nine months ended September 30, 2024 consists of underwriting income of $37.2 million (95.6% combined ratio) and net services income of $34.2 million, compared to underwriting income of $34.8 million (96.3% combined ratio) and net services income of $34.7 million for the nine months ended September 30, 2023. The improvement in underwriting income of $2.4 million for the nine months ended September 30, 2024 compared to the nine months ended September 30, 2023 was primarily driven by lower attritional losses in A&H.

Total net investment income and realized and unrealized investment gains for the three months ended September 30, 2024 was primarily attributable to net investment income related to interest income from our debt and short-term investment portfolio of $81.5 million. Increased investment income is primarily due to increased interest rates and our rotation of the portfolio from cash and cash equivalents and U.S. government and government agency positions to high-grade corporate debt and other securitized assets, in an effort to better diversify our portfolio.

Total net investment income and realized and unrealized investment gains (losses) for the three months ended September 30, 2023 was primarily attributable to investment results from our debt and short-term investment portfolio of $71.0 million driven by dividend and interest income primarily on U.S. treasury bill and corporate debt positions.

Total net investment income and realized and unrealized investment gains (losses) for the nine months ended September 30, 2024 was primarily attributable to net investment income related to interest income from our debt and short-term investment portfolio of $228.5 million, partially offset by unrealized losses on other long-term investments of $45.8 million. Increased investment income is primarily due to increased interest rates and our rotation of the portfolio from cash and cash equivalents and U.S. government and government agency positions to high-grade corporate debt and other securitized assets, in an effort to better diversify our portfolio. Losses on private other long-term investments were the result of updated fair value analyses consistent with the current insurtech market trends and disposals of positions as we execute our strategy to focus on underwriting relationships with MGAs.

Total net investment income and realized and unrealized investment gains for the nine months ended September 30, 2023 was primarily attributable to net investment income related to interest income from our debt and short-term investment portfolio of $208.5 million. Increased dividend and investment income is due to the ongoing re-positioning of the portfolio to focus on investing in high grade fixed income securities.

Forward-looking statements are subject to known and unknown risks and uncertainties, many of which may be beyond the Company’s control. The Company cautions you that the forward-looking information presented in this press release is not a guarantee of future events, and that actual events may differ materially from those made in or suggested by the forward-looking information contained in this press release. In addition, forward-looking statements generally can be identified by the use of forward-looking terminology such as “believes,” “intends,” “seeks,” “anticipates,” “aims,” “plans,” “targets,” “estimates,” “expects,” “assumes,” “continues,” “guidance,” “should,” “could,” “will,” “may” and the negative of these or similar terms and phrases. Specific forward-looking statements in this press release include, but are not limited to, statements regarding the trend of our performance as compared to the previous guidance, the success of our strategic transaction with CMIG International Holding Pte. Ltd., the current insurtech market trends, our ability to generate shareholder value and whether we will continue to have momentum in our business in the future. Actual events, results and outcomes may differ materially from the Company’s expectations due to a variety of known and unknown risks, uncertainties and other factors. Among the risks and uncertainties that could cause actual results to differ from those described in the forward-looking statements are the following: our ability to execute on our strategic transformation, including re-underwriting to reduce volatility and improving underwriting performance, de-risking our investment portfolio, and transforming our business; the impact of unpredictable catastrophic events such as uncertainties with respect to COVID-19 losses across many classes of insurance business and the amount of insurance losses that may ultimately be ceded to the reinsurance market, supply chain issues, labor shortages and related increased costs, changing interest rates and equity market volatility; inadequacy of loss and loss adjustment expense reserves, the lack of available capital, and periods characterized by excess underwriting capacity and unfavorable premium rates; the performance of financial markets, impact of inflation and interest rates, and foreign currency fluctuations; our ability to compete successfully in the insurance and reinsurance market and the effect of consolidation in the insurance and reinsurance industry; technology breaches or failures, including those resulting from a malicious cyber-attack on us, our business partners or service providers; the effects of global climate change, including increased severity and frequency of weather-related natural disasters and catastrophes and increased coastal flooding in many geographic areas; geopolitical uncertainty, including the impact of the U.S. November 2024 presidential and congressional elections, and ongoing conflicts in Europe and the Middle East; our ability to retain key senior management and key employees; a downgrade or withdrawal of our financial ratings; fluctuations in our results of operations; legal restrictions on certain of SiriusPoint’s insurance and reinsurance subsidiaries’ ability to pay dividends and other distributions to SiriusPoint; the outcome of legal and regulatory proceedings and regulatory constraints on our business; reduced returns or losses in SiriusPoint’s investment portfolio; our exposure or potential exposure to corporate income tax in Bermuda and the E.U., U.S.

federal income and withholding taxes and our significant deferred tax assets, which could become devalued if we do not generate future taxable income or applicable corporate tax rates are reduced; risks associated with delegating authority to third party managing general agents, managing general underwriters and/or program administrators; future strategic transactions such as acquisitions, dispositions, investments, mergers or joint ventures; SiriusPoint’s response to any acquisition proposal that may be received from any party, including any actions that may be considered by the Company’s Board of Directors or any committee thereof; and other risks and factors listed under "Risk Factors" in the Company's most recent Annual Report on Form 10-K and other subsequent periodic reports filed with the Securities and Exchange Commission.

All forward-looking statements speak only as of the date made and the Company undertakes no obligation to update or revise publicly any forward-looking statements, whether as a result of new information, future events or otherwise.

In presenting SiriusPoint’s results, management has included financial measures that are not calculated under standards or rules that comprise accounting principles generally accepted in the United States (“GAAP”). SiriusPoint’s management uses this information in its internal analysis of results and believes that this information may be informative to investors in gauging the quality of SiriusPoint’s financial performance, identifying trends in our results and providing meaningful period-to-period comparisons. Core underwriting income, Core net services income, Core income, and Core combined ratio are non-GAAP financial measures. Management believes it is useful to review Core results as it better reflects how management views the business and reflects the Company’s decision to exit the runoff business. Tangible book value per diluted common share is also a non-GAAP financial measure and the most directly comparable U.S. GAAP measure is book value per common share. Tangible book value per diluted common share excludes intangible assets. Management believes that effects of intangible assets are not indicative of underlying underwriting results or trends and make book value comparisons to less acquisitive peer companies less meaningful. Tangible book value per diluted common share is useful because it provides a more accurate measure of the realizable value of shareholder returns, excluding intangible assets. Underlying net income and underlying annualized return on equity on average common shareholders’ equity ("ROE") are non-GAAP financial measures. Underlying net income excludes gains (losses) on strategic investments and liability-classified capital instruments, income (expense) related to loss portfolio transfers and development on COVID-19 reserves. Underlying ROE is calculated by dividing annualized underlying net income available to SiriusPoint common shareholders for the period by the average common shareholders’ equity, excluding accumulated other comprehensive income (loss) ("AOCI"). Management believes it is useful to review underlying net income as it better reflects how it views the business and exclude AOCI because it may fluctuate significantly between periods based on movements in interest and currency rates. Reconciliations of such non-GAAP financial measures to the most directly comparable GAAP figures are included in the attached financial information in accordance with Regulation G and Item 10(e) of Regulation S-K, as applicable.

(1)Underwriting ratios are calculated by dividing the related expense by net premiums earned.

(2)Insurance & Services MGAs recognize fees for service using revenue from contracts with customers accounting standards, whereas insurance companies recognize acquisition expenses using insurance contract accounting standards. While ultimate revenues and expenses recognized will match, there will be recognition timing differences based on the different accounting standards.

Collectively, the sum of the Company's two segments, Reinsurance and Insurance & Services, constitute "Core" results. Core underwriting income, Core net services income, Core income and Core combined ratio are non-GAAP financial measures. We believe it is useful to review Core results as it better reflects how management views the business and reflects our decision to exit the runoff business. The sum of Core results and Corporate results are equal to the consolidated results of operations.

Core underwriting income - calculated by subtracting loss and loss adjustment expenses incurred, net, acquisition costs, net, and other underwriting expenses from net premiums earned.

Core net services income - consists of services revenues which include commissions, brokerage and fee income related to consolidated MGAs, and other revenues, and services expenses which include direct expenses related to consolidated MGAs, services noncontrolling income which represent minority ownership interests in consolidated MGAs. Net services income is a key indicator of the profitability of the Company's services provided.

Core income - consists of two components, core underwriting income and core net services income. Core income is a key measure of our segment performance.

Core combined ratio - calculated by dividing the sum of Core loss and loss adjustment expenses incurred, net, acquisition costs, net and other underwriting expenses by Core net premiums earned. Accident year loss ratio and accident year combined ratio are calculated by excluding prior year loss reserve development to present the impact of current accident year net loss and loss adjustment expenses on the Core loss ratio and Core combined ratio, respectively. Attritional loss ratio excludes catastrophe losses from the accident year loss ratio as they are not predictable as to timing and amount. These ratios are useful indicators of our underwriting profitability.

Tangible book value per diluted common share, as presented, is a non-GAAP financial measure and the most directly comparable U.S. GAAP measure is book value per common share. Tangible book value per diluted common share excludes intangible assets. Management believes that effects of intangible assets are not indicative of underlying underwriting results or trends and make book value comparisons to less acquisitive peer companies less meaningful. Tangible book value per diluted common share is useful because it provides a more accurate measure of the realizable value of shareholder returns, excluding intangible assets.

The following table sets forth the computation of book value per common share, book value per diluted common share and tangible book value per diluted common share as of September 30, 2024 and December 31, 2023:

Annualized return on average common shareholders’ equity attributable to SiriusPoint common shareholders is calculated by dividing annualized net income available to SiriusPoint common shareholders for the period by the average common shareholders’ equity determined using the common shareholders’ equity balances at the beginning and end of the period.

Annualized return on average common shareholders’ equity attributable to SiriusPoint common shareholders for the three and nine months ended September 30, 2024 and 2023 was calculated as follows:
