Q3 2025 INVESTOR PRESENTATION October 30, 2025 NYSE: SPNT
Basis of Presentation and Non-GAAP Financial Measures: Unless the context otherwise indicates or requires, as used in this presentation references to “we,” “our,” “us,” the “Company,” and "SiriusPoint" refer to SiriusPoint Ltd. and its directly and indirectly owned subsidiaries, as a combined entity, except where otherwise stated or where it is clear that the terms mean only SiriusPoint Ltd. exclusive of its subsidiaries. We have made rounding adjustments to reach some of the figures included in this presentation and, unless otherwise indicated, percentages presented in this presentation are approximate. 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, Core combined ratio, accident year loss ratio, accident year combined ratio, attritional loss ratio and attritional 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. 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. A reconciliation of these non-GAAP financial measures to the most directly comparable GAAP measure is contained in our Form 10-Q, earnings release or financial Supplement for the quarter ended September 30, 2025.
