Sid Sankaran, Chairman and Chief Executive Officer of SiriusPoint said: “I am delighted in our launch of SiriusPoint in the first quarter. We believe our combined company has the platform, capabilities and expertise to take advantage of changing market conditions and compete in a differentiated and effective fashion in the global (re)insurance marketplace. I am extremely proud that by the closing of our transaction we added world-class talent to our team, strengthened the quality of our balance sheet and refocused our underwriting strategy allowing us to benefit from a strong 1/1 renewal season. We are creating an entrepreneurial and innovative company that is just at the beginning of its transformation.

“SiriusPoint produced an underwriting profit of $9 million and a combined ratio of 96.6% this quarter, reflecting our focus on writing a profitable and more balanced book of business. We benefited from a focus on underwriting discipline and positive rate improvement across classes of business at January 1. We made great strides in refining our property cat portfolio, reducing catastrophe volatility through modest additional retro reinsurance purchases and rebalancing the overall portfolio to non-cat lines, including Accident and Health, Credit, Aviation, and niche U.S. Casualty lines. Through the rest of 2021, we plan to continue to execute on our underwriting strategy and be disciplined in our approach to managing risk. We are focused on better managing our catastrophe exposure and return on capital. We also plan to be disciplined in reducing classes which have been unprofitable. We believe our global platform and entrepreneurial culture will give us flexibility and culture to adapt to market conditions and be responsive to opportunities. While there is much work ahead we are confident we are making progress in our execution.

“We intend to remain nimble and optimize our global platform by partnering with and investing in innovative businesses and teams in the (re)insurance industry. We see these strategic partnerships as a key differentiator and a means by which we can add value and drive disruptive change in the industry. We aspire to be great allocators of capital to the best underwriting risks to drive returns.

“Investment results in the quarter were strong and above trend with notable contributions from the Third Point Enhanced Fund and legacy Sirius Group strategic investments. In rebalancing our portfolio, we increased the allocation to fixed income and cash from TPRe’s position at year end. Third Point LLP also reduced leverage in the TP Enhanced fund.

“We expect the steps we have taken this quarter towards refining our business to achieve underwriting excellence and establishing a high quality balance sheet will result in less volatility going forward. We are confident the path of sustained higher underwriting returns, less volatile investment results and growth in book value will translate into long-term value creation for our shareholders.”

Earnings Summary
Net income available to SiriusPoint common shareholders of $130.9 million, or $1.05 per diluted common share, for the three months ended March 31, 2021, compared to a net loss attributable to SiriusPoint common shareholders of $183.6 million, or $1.99 per diluted common share, for the three months ended March 31, 2020.
Annualized return on average common shareholders’ equity attributable to SiriusPoint common shareholders of 26.4% for the three months ended March 31, 2021.





Tangible diluted book value per share decreased $2.74, or 16.4%, from year end 2020 to $13.97. The decrease was primarily due to the dilutive impact of shares and other securities issued in conjunction with the acquisition of Sirius Group, partially offset by net income in the current year period.
Acquisition of Sirius International Insurance Group, Ltd.
On February 26, 2021, the Company completed the acquisition of Sirius International Insurance Group, Ltd. (“Sirius Group”) and changed its name from Third Point Reinsurance Ltd. (“TPRe”) to SiriusPoint Ltd. (“SiriusPoint”). The financial condition and results of operations presented herein for SiriusPoint are those of TPRe and its subsidiaries and do not include the financial conditions and results of operations of legacy Sirius Group and its subsidiaries prior to the acquisition date. The results of operations of Sirius Group are included from the acquisition date forward.
The total deal consideration was $1,077.2 million, which was comprised of stock, cash, and other contingent value components. The associated bargain purchase gain from the Sirius Group acquisition was $8.6 million, which represents the excess of the fair value of the underlying net assets acquired and liabilities assumed over the total deal consideration. The gain from bargain purchase is included in other revenues in the condensed consolidated statements of income (loss). The bargain purchase determination is consistent with the fact that Sirius Group’s shares traded at a discount to book value and the need for Sirius Group to quickly diversify its ownership base.
During the first quarter of 2021, the Company recorded $40.4 million of corporate expenses associated with the acquisition of Sirius Group, comprised of $29.7 million of professional and advisory fees and $10.7 million of compensation-related expenses.

First Quarter 2021 Summary
Underwriting Results
The acquisition of Sirius Group has created a highly diversified portfolio with expanded underwriting capabilities, geographic footprint and product offerings. Effective January 1, 2021, the Company reports four operating segments: Accident & Health (“A&H”), Specialty, Property and Runoff & Other.
In addition, effective January 1, 2021, the Company changed its accounting policy for assumed written premium recognition. Previously, the Company estimated ultimate premium written for the entire contract period and recorded this estimate at inception of the contract. The Company changed its accounting policy to recognize premiums written ratably over the term of the related policy or reinsurance treaty. The change in accounting policy had no impact on the previously reported net income (loss) or shareholders’ equity attributable to SiriusPoint common shareholders.





Net premiums earned increased by $109.7 million, or 75.0%, to $256.0 million for the three months ended March 31, 2021 from $146.3 million for the three months ended March 31, 2020, primarily driven by an increase in net premiums earned of $115.9 million as a result of new premiums from the legacy Sirius Group companies from the date of acquisition.
We generated net underwriting income of $8.7 million and a combined ratio of 96.6% for the three months ended March 31, 2021, compared to net underwriting income of $2.0 million and a combined ratio of 98.6% for the three months ended March 31, 2020. The improvement in net underwriting income was primarily driven by net underwriting income of $8.1 million from the legacy Sirius Group companies from the date of acquisition.
Catastrophe losses, net of reinsurance and reinstatement premiums, for the three months ended March 31, 2021 were $5.7 million, or 2.2 percentage points on the combined ratio, from winter storm Uri compared to no catastrophe losses recorded for the three months ended March 31, 2020. Sirius Group’s Uri losses fell into the pre-acquisition period which, when included Q1 results total catastrophe losses, were $39.5 million.
Prior period segment results have been adjusted to conform to the current period presentation.
A&H Segment
Gross premiums written in the A&H segment were $134.8 million for the three months ended March 31, 2021, an increase of $133.5 million compared to the three months ended March 31, 2020, primarily driven by an increase in premiums of $135.0 million as a result of new premiums from the legacy Sirius Group companies from the date of acquisition.
The A&H segment generated net underwriting income of $5.3 million and a combined ratio of 84.9% for the three months ended March 31, 2021, compared to a minimal net underwriting loss for the three months ended March 31, 2020. The change in net underwriting results for the three months ended March 31, 2021, compared to the three months ended March 31, 2020, was primarily driven by net underwriting income from the legacy Sirius Group companies from the date of acquisition.
Specialty Segment
Gross premiums written in the Specialty segment were $167.7 million for the three months ended March 31, 2021, an increase of $88.3 million, or 111.2%, compared to the three months ended March 31, 2020, primarily driven by an increase in premiums of $49.5 million as a result of new premiums from the legacy Sirius Group companies from the date of acquisition, and due to new casualty premium of $28.7 million in the period written by our Bermuda incorporated MGU, Arcadian Risk, in which we invest capital and expertise.
The Specialty segment generated a net underwriting loss of $0.3 million and a combined ratio of 100.2% for the three months ended March 31, 2021, compared to a net underwriting loss of $6.0 million and a combined ratio of 106.0% for the three months ended March 31, 2020. The change in underwriting results for the three months ended March 31, 2021, compared to the three months ended March 31, 2020, was primarily driven by lower COVID-19 losses and a net underwriting loss of $0.7 million as result of the legacy Sirius Group companies from the date of acquisition.
Property Segment
Gross premiums written in the Property segment were $62.1 million for the three months ended March 31, 2021, an increase of $17.1 million, or 38.0%, compared to the three months ended March 31, 2020, primarily driven by an increase in premiums of $33.5 million as a result of new premiums from the legacy Sirius Group companies from the date of acquisition.
The Property segment generated net underwriting income of $5.4 million and a combined ratio of 93.3% for the three months ended March 31, 2021, compared to net underwriting income of $9.5 million and a combined ratio of 78.9% for the three months ended March 31, 2020. The change in underwriting results for the three months ended March 31, 2021, compared to the three months ended March 31, 2020, was primarily driven by higher catastrophe losses, partially offset by net underwriting income of $3.9 million as a result of the legacy Sirius Group companies from the date of acquisition.
Investments
Net investment income was $186.5 million for the three months ended March 31, 2021, compared to a net investment loss of $185.0 million for the three months ended March 31, 2020.
Net investment income for the three months ended March 31, 2021 was primarily attributable to net investment income of $153.2 million from our investment in the TP Enhanced Fund, corresponding to a 14.6% return in the quarter. The return was primarily attributable to long event/fundamental equities, in particular exposure to recently listed public equities and private companies that are preparing to list in public markets later in 2021. In addition, the Company recognized a $35.4 million gain from our investment in Pie Insurance for the three months ended March 31, 2021, partially offset by unrealized losses in debt securities of $16.9 million.





The net investment loss for the three months ended March 31, 2020 was primarily attributable to financial market volatility from the COVID-19 pandemic.
The Third Point Enhanced Fund plus other invested assets were one-quarter of total invested assets and cash as of March 31, 2021, down from more than one-third as of December 31, 2020 due to the additional assets acquired in the merger with Sirius Group.

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. Book value per share metrics are non-GAAP financial measures. We believe that long-term growth in book value per share is an important measure of our financial performance because it allows our management and investors to track over time the value created by the retention of earnings. In addition, we believe this metric is used by investors because it provides a basis for comparison with other companies in our 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.

NON-GAAP MEASURES AND RECONCILIATIONS & KEY PERFORMANCE INDICATORS
Key Performance Indicator
Annualized Return on Average Common Shareholders’ Equity Attributable to SiriusPoint Common Shareholders
Annualized return on average common shareholders’ equity attributable to SiriusPoint common shareholders is calculated by dividing annualized net income (loss) 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 months ended March 31, 2021 and 2020 was calculated as follows:

Net Underwriting Income
We measure segment performance for our underwriting segments based on net underwriting income or loss. Net underwriting income is a pre-tax measure of underwriting profitability that takes into account net premiums earned as revenues, including service fee revenue from the Company’s managing general underwriting subsidiaries, and loss and loss adjustment expenses incurred, net, acquisition costs, net, and other underwriting expenses as expenses. Other underwriting expenses include those operating expenses that are incremental and/or directly attributable to our individual underwriting operations. See the accompanying Segment Reporting above for a calculation of net underwriting income.
Combined Ratio
Combined ratio is calculated by dividing the sum of loss and loss adjustment expenses incurred, net, acquisition costs, net and other underwriting expenses by net premiums earned. This ratio is a key indicator of a company’s underwriting profitability. See the accompanying Segment Reporting above for a calculation of the combined ratio.
Basic Book Value Per Share, Tangible Basic Book Value Per Share, Diluted Book Value Per Share, Tangible Diluted Book Value Per Share
In the first quarter of 2021, we changed the method for calculating the dilutive effect of restricted shares, restricted share units and options to calculate the dilutive impact in a manner consistent with how dilution is calculated using the treasury stock method for earnings per share. This change had no impact on previously presented basic book value per share. The following table shows the revised diluted book value per share compared to the diluted book value per share as previously presented:

Basic book value per share, as presented, is a non-GAAP financial measure and is calculated by dividing common shareholders’ equity attributable to SiriusPoint common shareholders by the number of common shares outstanding, excluding the total number of issued unvested restricted shares, at period end.
Tangible basic book value per share, as presented, is a non-GAAP financial measure and is calculated by dividing tangible common shareholders’ equity attributable to SiriusPoint common shareholders by the number of common shares outstanding, excluding the total number of unvested restricted shares, at period end. Tangible book value per share is useful to investors because it measures the realizable value of shareholder returns, excluding the impact of intangible assets.





Diluted book value per share and tangible diluted book value per share, as presented, are non-GAAP financial measures and are calculated using the treasury stock method. Under the treasury stock method, we assume that proceeds received from in-the-money options and/or warrants exercised are used to repurchase common shares in the market. The dilutive effect of restricted shares, restricted share units and options are calculated in a manner consistent with how dilution is calculated using the treasury stock method for earnings per share. We have also followed a similar approach for calculating dilution for warrants, Series A preference shares, Upside Rights and other potentially dilutive securities issued as part of our acquisition of Sirius Group.
The following table sets forth the computation of basic book value per share, tangible basic book value per share, diluted book value per share and tangible diluted book value per share as of March 31, 2021 and December 31, 2020:
