DISCLAIMER Non-GAAP Financial Measures This presentation may also contain non-GAAP financial information. 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 important to review Core results as it better reflects how management views the business and reflects the Company’s decision to exit the runoff business. Basic book value per share, tangible basic book value per share, diluted book value per share and tangible diluted book value per share are also non-GAAP financial measures. SiriusPoint’s management believes that long-term growth in book value per share is an important measure of the Company’s financial performance because it allows management and investors to track over time the value created by the retention of earnings. In addition, SiriusPoint’s management believes this metric is useful to investors because it provides a basis for comparison with other companies in the industry that also report a similar measure. Reconciliations of such measures to the most comparable GAAP figures are included in the attached financial information in accordance with Regulation G. 2 Forward- Looking Statements We make statements in this report that are forward-looking statements within the meaning of the U.S. federal securities laws.
