Basis of Presentation and Non-GAAP Financial Measures:

Unless the context otherwise indicates or requires, as used in this financial supplement 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 financial supplement and, unless otherwise indicated, percentages presented in this financial supplement 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, 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.
