HAMILTON, Bermuda, Aug. 02, 2023 (GLOBE NEWSWIRE) -- SiriusPoint Ltd. (“SiriusPoint” or the “Company”) (NYSE:SPNT) today announced results for its second quarter ended June 30, 2023.

• Building on the progress made during the last three quarters as we report positive capital generation across all business areas and deliver on key strategic priorities
• Capital position is even stronger following the closure of the loss portfolio transfer, asset and financial leverage remains stable while our investment portfolio remains defensively positioned
• Targeting double-digit return on average common equity in 2023, reiterating guidance on 2024 cost savings of >$50 million and 2023 net investment income of $220-240 million
  

Scott Egan, Chief Executive Officer, said: “This quarter has been a positive one for SiriusPoint with all three areas of our business performing well as we continue our journey to improve the performance of the company.

Our underwriting results are strong, with a combined ratio of 84.4% for our core operations. Our investment portfolio remains focused on high quality, fixed income instruments and we are tracking to the top-end of our full year 2023 net investment income guidance of $220 million to $240 million. Run-rate costs have been reduced by $35 million to $40 million versus previous year on an underlying basis and we are confident on our target of more than $50 million reduction by the end of 2024. The balance sheet is even stronger now given we have closed the loss portfolio transfer deal, releasing more than $150 million of capital and aligning our balance sheet to the go forward strategy. Finally, all areas of our business are capital generating and we are on track to hit double-digit ROE this year.

We are also making significant progress to improve culture and employee engagement with the intention to create a high performing organization. We have great talent across the organization and I am proud of their efforts in delivering these results.

Exploratory discussions with Mr. Daniel Loeb regarding a potential acquisition began and concluded this quarter, following his 13-D filing, and we appreciate the Special Committee of the Board’s support of our strategy. We welcomed Bronek Masojada to the role of Chair of the Board. He is a proven industry leader with over 30 years of insurance experience, who will further strengthen our Board.

Our focus on executing well against our strategy continues and with each quarter that passes, we build more credibility and track record. Our aim is to keep doing this and I look forward to sharing further progress later in the year.”

Second Quarter 2023 Summary

Consolidated underwriting income for the three months ended June 30, 2023 was $127.3 million compared to $38.8 million for the three months ended June 30, 2022. The improvement in net underwriting results was driven by improved favorable prior year loss reserve development of $33.0 million for the three months ended June 30, 2023 compared to $6.4 million for the three months ended June 30, 2022. This increase in favorable prior year loss reserve development was primarily the result of management reflecting the continued favorable reported loss emergence through June 30, 2023 in its best estimate of reserves, which was further validated by the pricing of the loss portfolio transfer transaction (“2023 LPT”) from external reinsurers, including $16.6 million resulting from a reduction in unallocated loss adjustment expenses related to the claims that will no longer be managed by SiriusPoint under the terms of the 2023 LPT. In addition, there were no property catastrophe losses for the three months ended June 30, 2023 compared to $16.2 million for the three months ended June 30, 2022.

Consolidated underwriting income for the six months ended June 30, 2023 was $283.8 million compared to $72.3 million for the six months ended June 30, 2022. The improvement in net underwriting results was driven by improved favorable prior year loss reserve development of $138.4 million for the six months ended June 30, 2023 compared to $11.9 million for the six months ended June 30, 2022. This increase in favorable prior year loss reserve development was primarily the result of management reflecting the continued favorable reported loss emergence through June 30, 2023 in its best estimate of reserves, which was further validated by the pricing of the 2023 LPT from external reinsurers, which represents $118.2 million of the favorable prior year loss reserve development. In addition, catastrophe losses, net of reinsurance and reinstatement premiums, were $12.9 million, or 1.0 percentage points on the combined ratio, for the six months ended June 30, 2023, compared to $23.1 million, or 2.1 percentage points on the combined ratio, for the six months ended June 30, 2022. The lower catastrophe losses were a result of the Company’s significant reduction in catastrophe exposed business.

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 - Reinsurance and Insurance & Services.

Core Underwriting Results

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

Three months ended June 30, 2023 and 2022

Core results for the three months ended June 30, 2023 included income of $85.3 million compared to income of $20.2 million for the three months ended June 30, 2022. Income for the three months ended June 30, 2023 consists of underwriting income of $81.7 million (87.7% combined ratio) and net services income of $3.6 million, compared to underwriting income of $9.6 million (98.3% combined ratio) and net services income of $10.6 million for the three months ended June 30, 2022. The improvement in net underwriting results was primarily driven by increased favorable prior year loss reserve development, lower catastrophe losses and favorable expense ratios (both commission and other underwriting expense ratios), which results in a higher underwriting gain. Net services income for the three months ended June 30, 2023 included net investment losses from Strategic Investments of $4.1 million compared to losses of $0.5 million for the three months ended June 30, 2022.

Losses incurred included $25.2 million of favorable prior year loss reserve development for the three months ended June 30, 2023, compared to $1.5 million for the three months ended June 30, 2022. For the three months ended June 30, 2023, favorable prior year loss reserve development was driven by decreases in the domestic and international property and casualty lines of business in the Reinsurance segment, partially offset by loss emergence in the property and casualty business lines in the Insurance & Service segment. This increase in favorable prior year loss reserve development was primarily the result of management reflecting the continued favorable reported loss emergence through June 30, 2023 in its best estimate of reserves, which was further validated by the pricing of the 2023 LPT from external reinsurers, in addition to a reduction in unallocated loss adjustment expense reserves related to the claims that will no longer be managed by SiriusPoint under the terms of the 2023 LPT.

For the three months ended June 30, 2023, there were no significant catastrophe losses compared to $16.2 million, or 2.9 percentage points on the combined ratio, for the three months ended June 30, 2022.

Six months ended June 30, 2023 and 2022

Core results for the six months ended June 30, 2023 included income of $205.5 million compared to income of $46.9 million for the six months ended June 30, 2022. The income for the six months ended June 30, 2023 consists of an underwriting income of $189.1 million (84.4% combined ratio) and net services income of $16.4 million, compared to an underwriting income of $22.3 million (98.0% combined ratio) and net services income of $24.6 million for the six months ended June 30, 2022. The improvement in net underwriting results was primarily driven by favorable prior year loss reserve development, lower catastrophe losses, and favorable expense ratios (both commission and other underwriting expense ratios), which results in a higher underwriting gain. Net services income for the six months ended June 30, 2023 included net investment losses from Strategic Investments of $8.0 million compared to losses of $0.8 million for the six months ended June 30, 2022.

Losses incurred included $117.1 million of favorable prior year loss reserve development for the six months ended June 30, 2023 compared to favorable prior year loss reserve development of $6.5 million for the six months ended June 30, 2022. This increase in favorable prior year loss reserve development was primarily the result of management reflecting the continued favorable reported loss emergence through June 30, 2023 in its best estimate of reserves, which was further validated by the pricing of the 2023 LPT from external reinsurers, in addition to a reduction in unallocated loss adjustment expense reserves related to the claims that will no longer be managed by SiriusPoint under the terms of the 2023 LPT.

For the six months ended June 30, 2023, catastrophe losses, net of reinsurance and reinstatement premiums, were $7.0 million, or 0.6 percentage points on the combined ratio, compared to $23.1 million, or 2.1 percentage points on the combined ratio for the six months ended June 30, 2022. For the six months ended June 30, 2022, losses from the Russia/Ukraine conflict, including losses from the political risk, trade credit, and aviation lines of business, were $13.2 million, or 1.2 percentage points on the combined ratio.

Reinsurance Segment

Three months ended June 30, 2023 and 2022

Reinsurance generated underwriting income of $79.3 million (75.3% combined ratio) for the three months ended June 30, 2023, compared to an underwriting loss of $0.2 million (100.1% combined ratio) for the three months ended June 30, 2022. The improvement in net underwriting results was primarily due to increased favorable prior year loss reserve development and lower catastrophe losses.

Reinsurance gross premiums written were $387.1 million for the three months ended June 30, 2023, an increase of $8.8 million, or 2.3%, compared to the three months ended June 30, 2022, driven by growth in the property and casualty lines of business in the North America reinsurance business, partially offset by lower writings in International reinsurance, primarily in the property lines, as we execute the Restructuring Plan.

Six months ended June 30, 2023 and 2022

Reinsurance generated underwriting income of $156.4 million (72.5% combined ratio) for the six months ended June 30, 2023, compared to $2.9 million (99.6% combined ratio) for the six months ended June 30, 2022. The improvement in net underwriting results for the six months ended June 30, 2023 compared to the six months ended June 30, 2022 was primarily due to higher favorable prior year loss reserve development and lower catastrophe losses.

Reinsurance gross premiums written were $783.3 million for the six months ended June 30, 2023, a decrease of $119.2 million, or 13.2%, compared to the six months ended June 30, 2022, driven by lower writings in International reinsurance, primarily in the property lines, as we execute the Restructuring Plan.

Insurance & Services Segment

Three months ended June 30, 2023 and 2022

Insurance & Services generated segment income of $8.8 million for the three months ended June 30, 2023, compared to $20.4 million for the three months ended June 30, 2022. Segment income for the three months ended June 30, 2023 consists of underwriting income of $2.4 million (99.2% combined ratio) and net services income of $6.4 million, compared to underwriting income of $9.8 million (96.1% combined ratio) and net services income of $10.6 million for the three months ended June 30, 2022. The decrease in underwriting results was primarily due to decreased favorable prior year loss reserve development from loss emergence from certain strategic partnerships. The decrease in services income was primarily due to net investment losses from Strategic Investments of $4.1 million for the three months ended June 30, 2023 compared to $0.5 million for the three months ended June 30, 2022.

Insurance & Services gross premiums written were $462.7 million for the three months ended June 30, 2023, an increase of $28.8 million, or 6.6%, compared to the three months ended June 30, 2022, primarily driven by growth across Insurance & Services, including growth in premiums from strategic partnerships, mainly Arcadian.

Six months ended June 30, 2023 and 2022

Insurance & Services generated segment income of $49.1 million for the six months ended June 30, 2023, compared to $44.0 million for the six months ended June 30, 2022.

The increase in underwriting results was primarily driven by the increased favorable prior loss reserve development from better than expected reported loss emergence in A&H. The decrease in services income was primarily due to net investment losses from Strategic Investments of $8.0 million for the six months ended June 30, 2023 compared to $0.8 million for the six months ended June 30, 2022.

Insurance & Services gross premiums written were $1,126.7 million for the six months ended June 30, 2023, an increase of $209.3 million, or 22.8%, compared to the six months ended June 30, 2022, primarily driven by growth across Insurance & Services, including growth in premiums from strategic partnerships, mainly Arcadian and Corvus Insurance, and A&H.

Investments

Three months ended June 30, 2023 and 2022

Total realized and unrealized investment gains (losses) and net investment income was $65.8 million for the three months ended June 30, 2023, compared to $(141.5) million for the three months ended June 30, 2022.

Total realized and unrealized investment gains and net investment income for the three months ended June 30, 2023 was primarily attributable to investment results from our debt and short-term investment portfolio of $64.9 million. These fixed income positions returned 0.1% in U.S. dollars and an original currency basis, inclusive of marked to market losses on available for sale securities of $52.7 million. Investment results were driven by dividend and interest income primarily on U.S. treasury bills and corporate debt positions which make up 46.6% of our total investments as of June 30, 2023, compared to 28.5% of our portfolio as of June 30, 2022.

Investment results for the three months ended June 30, 2022 were primarily attributable to the net investment loss of $57.3 million from our investment in the TP Enhanced Fund, corresponding to a (12.5)% return.

Six months ended June 30, 2023 and 2022

Total realized and unrealized investment gains (losses) and net investment income was $139.6 million for the six months ended June 30, 2023, compared to $(346.6) million for the six months ended June 30, 2022.

Total realized and unrealized investment gains and net investment income for the six months ended June 30, 2023 was primarily attributable to net investment income related to interest income from our debt and short-term investment portfolio of $137.5 million.

Investment results for the six months ended June 30, 2022 were primarily attributable to the net investment loss of $185.6 million from our investment in the TP Enhanced Fund, corresponding to a (25.9)% return.

SiriusPoint International Loss Portfolio Transfer

On March 2, 2023, the Company agreed, subject to applicable regulatory approvals and other closing conditions, to enter into a loss portfolio transfer transaction (“2023 LPT”), on a funds withheld basis, with Pallas Reinsurance Company Ltd., a subsidiary of the Compre Group, an insurance and reinsurance legacy specialist. The transaction covered loss reserves ceded initially estimated at $1.3 billion as of the valuation date of September 30, 2022, which were reduced to $905.6 million as of June 30, 2023, as a result of paid losses and favorable prior accident year reserve development recognized during the interim period. Upon closing, the Company recorded funds held payable of $884.4 million and an initial estimate of a deferred gain of $21.2 million, which will be amortized over the claim payout period of the subject business.

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. Tangible book value per diluted common share is also a non-GAAP financial measure and the most comparable U.S. GAAP measure is book value per common share. Tangible book value per diluted common share excludes the total number of unvested restricted shares, at period end, and intangible assets. While restricted shares are outstanding, they are excluded because they are unvested. Further, 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. The tangible book value per diluted common share is also useful because it provides a more accurate measure of the realizable value of shareholder returns, excluding intangible assets. Reconciliations of such measures to the most comparable GAAP figures are included in the attached financial information in accordance with Regulation G.

NON-GAAP FINANCIAL MEASURES AND RECONCILIATIONS & OTHER FINANCIAL MEASURES

Non-GAAP Financial Measures

Core Results

Collectively, the sum of the Company's two segments, Reinsurance and Insurance & Services, 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, services expenses which include direct expenses related to consolidated MGAs, services noncontrolling income which represent minority ownership interests in consolidated MGAs, and net investment gains from Strategic Investments which are net investment gains/losses from investment in our strategic partners. Net services income is a key indicator of the profitability of the Company's services provided, including investment returns on non-consolidated investment positions held.

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.

Tangible Book Value Per Diluted Common Share

Tangible book value per diluted common share, as presented, is a non-GAAP financial measure and the most comparable U.S. GAAP measure is book value per common share. Tangible book value per diluted common share excludes the total number of unvested restricted shares, at period end, and intangible assets. While restricted shares are outstanding, they are excluded because they are unvested. Further, 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. The tangible book value per diluted common share is also 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 June 30, 2023 and December 31, 2022:

Other Financial Measures

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 and six months ended June 30, 2023 and 2022 was calculated as follows:
