Reportable Segments
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 - Insurance & Services and Reinsurance.
Collectively, the sum of our two segments, Insurance & Services and Reinsurance, 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.

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 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 improve underwriting performance, de-risking our investment portfolio, and transforming our business; the impact of unpredictable catastrophic events, including uncertainties with respect to losses from health pandemics 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 wildfires, and increased severity and frequency of weather-related natural disasters and catastrophes and increased coastal flooding in many geographic areas; geopolitical uncertainty, including the ongoing conflicts in Europe and the Middle East and the uncertainty from policies under the current presidential administration in the U.S., such as the federal government shutdown and financial markets' and businesses' reactions to such events; global economic uncertainty caused by the imposition and/or announcement of tariffs imposed on the import of certain goods into the U.S. from various countries which may have unpredictable consequences including, but not limited to, inflation or trade wars, potential impact on the Company’s credit and mortgage business and potential increase in credit spread which could impact the Company’s short-term capital and liquidity; 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; future strategic transactions such as acquisitions, dispositions, investments, mergers or joint ventures; 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.
Non-GAAP Financial Measures and Other Financial Metrics
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. Book value per diluted common share excluding accumulated other comprehensive income (loss) ("AOCI") and tangible book value per diluted common share, as presented, are non-GAAP financial measures and the most directly comparable U.S. GAAP measure is book value per common share. Management believes it is useful to exclude AOCI because it may fluctuate significantly between periods based on movements in interest and currency rates. Management believes the 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. 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.

SIRIUSPOINT LTD.
NON-GAAP FINANCIAL MEASURES AND RECONCILIATIONS & OTHER FINANCIAL MEASURES
Non-GAAP Financial Measures
Core Results
Collectively, the sum of the Company's two segments, Insurance & Services and Reinsurance, 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, as well as services expenses which include direct expenses related to consolidated MGAs and 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.
Book Value Per Diluted Common Share Metrics
Book value per diluted common share excluding AOCI and tangible book value per diluted common share, as presented, are non-GAAP financial measures and the most directly comparable U.S. GAAP measure is book value per common share. Management believes it is useful to exclude AOCI because it may fluctuate significantly between periods based on movements in interest and currency rates. 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, 2025 and December 31, 2024:

Operating Net Income, Operating Diluted Earnings per Share and Annualized Operating ROE
Operating net income and Operating diluted earnings per share are non-GAAP financial measures and the most directly comparable U.S. GAAP measure is net income and diluted earnings per share, respectively. Operating net income excludes items which we believe are not indicative of the operations of our operating businesses, including realized and unrealized gains (losses) on strategic and other investments and liability-classified capital instruments, income (expense) related to loss portfolio transfers, deferred tax assets attributable to the enactment of the Bermuda corporate income tax, development on COVID-19 reserves resulting from the COVID-19 reserve study performed concurrently with the settlement of the Series A Preference shares in the third quarter of 2024, and foreign exchange gains (losses). We believe it is useful to review Operating net income as it better reflects how we view the business, as well as provides investors with an alternative metric that can assist in predicting future earnings and profitability that are complementary to GAAP metrics. Annualized Operating ROE is calculated by dividing Operating net income for the period by average common shareholders’ equity, excluding AOCI, and after adjusting for the above noted items to arrive at Operating net income. Management believes it is useful to exclude AOCI because it may fluctuate significantly between periods based on movements in interest and currency rates.
The following table sets forth the computation of Operating net income and Operating diluted earnings per share for the three and nine months ended September 30, 2025 and 2024:
