Hamilton, Bermuda, April 19, 2023 - Aspen Insurance Holdings Limited (“Aspen”) today reported results for the twelve months ended December 31, 2022.

CEO statement

We have continued to make significant progress in 2022, generating $202 million of operating income* (2021: $51 million) and $51 million of net income (2021: $(30) million). We delivered a strong set of results in a challenging year that included Russia’s invasion of Ukraine, rising inflation and significant natural catastrophe activity, all of which generated notable loss activity for our industry.

Against this backdrop, our reported combined ratio improved to 93.0% (2021: 101.2%), an outstanding result. Adjusted for the impacts of the loss portfolio transfer and adverse development contracts, our combined ratio was 92.4%* (2021: 98.8%). We have been clear in our ambition to establish Aspen as a top quartile specialty (re)insurer and we have maintained momentum during 2022 through the strength of our underwriting performance and continued operational resilience.

Strong performance in our insurance and reinsurance businesses

The strength of Aspen’s franchise means we were well positioned to grow. We took advantage of the favorable market conditions in 2022, increasing our gross written premiums by approximately 10% to $4,339 million (2021: $3,938 million), while we continued to strategically shape the underwriting portfolio. We grew in both our insurance and reinsurance segments and the average rate increase across our overall renewed portfolio was 10%.

* Non-GAAP financial measures are used throughout this release, such as Operating Income and Adjusted Combined Ratio. For additional information and reconciliation of non-GAAP financial measures, refer to the end of this press release.

Refer to "Cautionary Statement Regarding Forward-Looking Statements" at the end of this press release.

The adjusted combined ratio of 92.4% represents a strong underwriting result for the year and reflects the quality of our portfolio following extensive repositioning in recent years. The continued improvement across the portfolio is driven by disciplined underwriting and rate increases exceeding loss costs. The loss portfolio transfer, completed in May 2022, improved the strength of our balance sheet and provides significant protection of future earnings from potential reserve development on 2019 and prior accident years. We continue to focus on risk management which included a reduction in our exposure to catastrophe losses. The benefits of this can be seen in our 2022 results, within the context of high industry catastrophe loss activity.

Our net investment income was up 28% to $188 million (2021: $148 million). Like the wider market, Aspen has not been immune from the impact of rising interest rates on our investment portfolio. As we said in our half-year 2022 statement, we broadly expect the unrealized investment losses to unwind as securities reach maturity, while higher interest rates will also positively impact future returns.

Encouraging results of our capital markets franchise

Aspen Capital Markets generated total fee income of $104 million, driven by an increase in assets under management to $1.3 billion. This fee income is primarily reflected as an offset to our acquisition costs and therefore benefits our underwriting results. Given the challenges facing the insurance-linked securities market in raising capital, this is testament to the innovative team we have and our track record of delivering for our investors.

Building a culture of which we are proud

I would like to thank our people for their commitment and the role they have played in instilling an innovative and collaborative culture that we can all be proud of. I firmly believe that this culture helps us attract and retain talent, maintain our strong market relationships and sustain an environment of high performance.

In 2022, work continued to build a more diverse, equitable and inclusive business. We established employee-led gender and ethnicity communities across the UK, US and Bermuda, and started collecting diversity data for our employees to better understand our workforce and create a welcoming working environment for all.

As we continue to grow and strive for excellence, it’s critical that we reward our people not only for what they do, but how they do it. Over the past few years, we have put significant emphasis on defining our values as a central part of Aspen’s culture. In 2023, we have taken a step forward and embedded values and behaviors into our annual performance cycle.

Earlier this year, we published our second Environmental Social and Governance (ESG) Report, building on the work started in 2021. The report shows steady progress across all three pillars of ESG, and the continued focus on embedding sustainability into Aspen’s strategy and values.

A business transformed and focused on delivering consistent performance

The results we have reported today mark the third consecutive year of improved underwriting performance. This is a reflection of our transformation efforts over the past few years as we simplified, reshaped and improved Aspen, taking decisive and timely actions on our risk appetite and exposures. Our proactive approach to portfolio management means we have a flexible, robust and diversified franchise across multiple product lines and geographies that provides value and support for our clients.

As a result, we are well-positioned to take advantage of the opportunities that the market is currently providing. Our focus remains on sustainable growth, optimizing our underwriting returns and prudently managing catastrophe risk, as we continue to work towards our objective of delivering consistent top quartile results.

•Gross written premiums of $4,339 million in the twelve months ended December 31, 2022, an increase of 10% compared to $3,938 million in the twelve months ended December 31, 2021, primarily due to rate improvement and growth in both of our underwriting segments.

•Underwriting income of $190 million (adjusted underwriting income* of $205 million) in the twelve months ended December 31, 2022, compared to an underwriting loss of $30 million (adjusted underwriting income of $28 million) in the twelve months ended December 31, 2021, resulting in a combined ratio of 93.0% (adjusted combined ratio of 92.4%) for the twelve months ended December 31, 2022, compared to 101.2% (adjusted combined ratio of 98.8%) for the twelve months ended December 31, 2021.

•Losses and loss adjustment expenses include:

◦Catastrophe losses of $307 million, or 11 percentage points on the combined ratio, for the twelve months ended December 31, 2022, included losses associated with Hurricane Ian, floods in Australia and South Africa, the Russian/Ukraine war and other weather-related events.

◦Remaining improvement in the loss ratio reflects improved pricing in excess of loss costs as well as the impact of portfolio repositioning from underwriting actions taken over the past few years across both our insurance and reinsurance segments.

•Acquisition costs as a percentage of net earned premium improved from 17% in 2021 to 16% in 2022, primarily within our insurance segment, due to a greater proportion of our business being ceded to Aspen Capital Markets businesses.

•General and administrative expenses increased to $387 million, representing 14 percentage points on the combined ratio, in the twelve months ended December 31, 2022, compared with $333 million, and 14 percentage points on the combined ratio, in the twelve months ended December 31, 2021.

Prior year net favorable reserve development of $134 million, or 12 percentage points on the combined ratio, in the twelve months ended December 31, 2021.

Investment performance

•Investment income of $188 million for the twelve months ended December 31, 2022, compared with $148 million for the twelve months ended December 31, 2021.

•Net realized and unrealized investment losses of $178 million in the twelve months ended December 31, 2022, which includes unrealized losses of $106 million. In addition, $368 million of unrealized investment losses after tax were recognized through other comprehensive income in the twelve months ended December 31, 2022, compared to $158 million in the twelve months ended December 31, 2021. Unrealized losses are due to higher interest rate and we would expect these to unwind as securities reach maturity. This compares to $9 million net realized and unrealized investment gains in the twelve months ended December 31, 2021, which includes net unrealized gain of $5 million.

•The total return, after tax, on Aspen’s managed investment portfolio was (4.8)% for the twelve months ended December 31, 2022, compared to (0.02)% in the twelve months ended December 31, 2021, and reflects net investment income and net realized and unrealized gains and losses mainly in the fixed income portfolio.

•Aspen’s investment portfolio as at December 31, 2022, consisted primarily of high quality fixed income securities with an average credit rating of “AA-”. The average duration of the fixed income securities was 3.0 years as at December 31, 2022 compared with 3.3 years as at December 31, 2021.

•Book yield on these fixed income securities as at December 31, 2022, was 3.2% compared with 2.1% as at December 31, 2021.

Shareholders’ equity

•Total shareholders’ equity was $2,358 million as at December 31, 2022, a decrease of $417 million, compared with $2,775 million as at December 31, 2021. The decrease is primarily due to unrealized losses in the available for sale investment portfolio of $368 million caused by the mark-to-market valuation impact from higher interest rates and credit spread widening. Additionally, the decrease was due to ordinary and preference dividends of $85 million, partially offset by net income of $51 million during the twelve months ended December 31, 2022.

Effective January 1, 2022, management reassessed its functional currency determination as required by ASC 830, Foreign Currency Matters, as a result of significant changes in the groups economic facts and circumstances, and concluded that the functional currency of certain of its foreign operations had changed. Consequently, Aspen has concluded that USD is now the functional currency for all its branches and overseas entities. The change in the Company’s functional currency determination has been applied on a prospective basis in accordance with ASC 830.

Adjusted combined ratio represents the performance of our business for accident years 2020 onwards, which reflects the underlying underwriting performance of the ongoing portfolio.

Aspen believes these factors include, but are not limited to: the actual development of losses and expenses impacting estimates for catastrophe, pandemic or other large property, casualty or specialty losses and the adequacy of reserves for such events; operating costs, stakeholder loss and business disruption (including, without limitation, difficulties in maintaining relationships with employees, customers, reinsurers or suppliers) related to pandemics may be greater than expected; Aspen's controlling shareholder owns all of its ordinary shares and has the power to affect the affairs of Aspen; the impact on our operating results and financial condition from our entry into a loss portfolio transfer arrangement reinsuring losses incurred with dates of loss on or prior to December 31, 2019 and the management and interpretation thereof and of any other forms of retrocessional coverage of legacy business; the impact of complex and unique causation and coverage issues associated with the attribution of losses to wind or flood damage or other perils such as fire or business interruption relating to such events; potential uncertainties relating to reinsurance recoveries, reinstatement premiums and other factors inherent in loss estimation; our ability to successfully implement steps to further optimize the business portfolio, ensure capital efficiency and enhance investment returns; the possibility of greater frequency or severity of claims and loss activity, including as a result of natural or man-made (including economic and political risks) catastrophic or material loss events, than our underwriting, reserving, reinsurance purchasing or investment practices have anticipated; the assumptions and uncertainties underlying reserve levels that may be impacted by future payments for settlements of claims and expenses or by other factors causing adverse or favorable development, including our assumptions on economic or social inflation costs which could differ materially from actual experience; the United Kingdom’s withdrawal from the European Union; a decline in our operating subsidiaries’ ratings or outlook with S&P or A.M. Best; the reliability of, and changes in assumptions to, natural and man-made catastrophe pricing, accumulation and estimated loss models; the models we use to assess our exposure to losses from future catastrophes contain inherent uncertainties and our actual losses may differ significantly from expectations, including in relation to the impact of climate change; our capital models may provide materially different indications than actual results; decreased demand for our insurance of reinsurance products; cyclical changes in the insurance and reinsurance industry; increased competition from existing insurers and (re)insurers and from alternative capital providers and insurance-linked funds and collateralized special purpose insurers on the basis of pricing, capacity, coverage terms, new capital, binding authorities to brokers or other factors and the related demand and supply dynamics as contracts come up for renewal; our ability to execute our business plan to enter new markets, introduce new products and teams and develop new distribution channels, including their integration into our existing operations; our acquisition strategy; the recent consolidation in the insurance and

reinsurance industry; loss of one or more of our senior underwriters, senior management or other key personnel; our ability to exercise capital management initiatives, including the availability of capital to declare dividends, or to arrange banking facilities as a result of prevailing market conditions, the level of catastrophes or other losses or changes in our financial results; changes in the method for determining the London Inter-bank Offered Rate (“LIBOR”) and the replacement of LIBOR with alternative benchmark rates; changes in capital models promulgated by, or changes in policies and practices of, one or more rating agencies applicable to Aspen; changes in general economic conditions including, but not limited to, inflation, deflation, stagnation, foreign currency exchange rates, interest rates, supply chain considerations and other factors that could affect our financial results; the impact of changing interest rates on our unrealized investment losses; the risk of a material decline in the value or liquidity of all or parts of our investment portfolio; the risks associated with the management of capital on behalf of investors; a failure in our operational systems or infrastructure or those of third parties, including those caused by security breaches or cyber-attacks, or data protection failures; evolving issues with respect to interpretation of coverage under the policies we have underwritten; our ability to adequately model and price the effects of climate cycles and climate change; any intervening legislative or governmental action and changing judicial interpretation and judgments on insurers’ and reinsurers’ liability to various risks; the risks related to litigation; the effectiveness of our risk management loss limitation methods, including our reinsurance purchasing; changes in the availability, cost or quality of reinsurance coverage; changes in the total industry losses or our share of total industry losses resulting from events, such as catastrophes, that have occurred in prior years or may occur and, with respect to such events, our reliance on loss reports received from clients, cedants and loss adjusters, our reliance on industry loss estimates and those generated by modeling techniques, changes in rulings on perils or other exclusions as a result of prevailing lawsuits and case law; the impact of one or more large losses from events other than catastrophes or by an unexpected accumulation of attritional losses and deterioration in loss estimates; the impact of acts of terrorism, acts of war and related legislation; any changes in our reinsurers’ credit quality and the amount and timing of reinsurance recoverables; the ability of reinsurers, managing general agents, third party administrators and other entities or persons to meet their obligations to Aspen; the continuing and uncertain impact of the current depressed lower growth economic environment in many of the countries in which we operate; our reliance on information and technology and third-party service providers for our operations and systems; the level of inflation in repair costs due to limited availability of labor and materials after catastrophes; the failure of our reinsurers, policyholders, brokers or other intermediaries to honor their payment obligations; our reliance on the assessment and pricing of individual risks by third parties; our dependence on a few brokers for a large portion of our revenues; statutory, case law or regulatory developments, including as to tax policy and insurance and reinsurance statutory or regulatory matters that would affect Bermuda-domiciled groups and Bermuda-based insurers and reinsurers and tax laws applicable to Aspen or certain of its subsidiaries or internal and external stakeholders; the impact of tax reform on Aspen’s business, investments, results and assets, including (i) changes to the valuation of deferred tax assets and liabilities, (ii) the impact on intra-group reinsurance transactions, (iii) that the costs associated with such tax reform may be greater than initially expected, and (iv) the risk that technical corrections, regulations and supplemental legislation and future interpretations or applications thereof or other changes may be issued in the future, including the rules affecting the valuation of deferred tax assets; changes in government regulations or tax laws in jurisdictions where we conduct business; changes in accounting principles or policies or in the application of such accounting principles or policies; central bank intervention in the financial markets, trade wars or other protectionist measures relating to international trade arrangements, adverse geopolitical events, domestic political upheavals or other developments that adversely impact global economic conditions; failure of our hedging arrangements to be effective; increased counterparty risk due to the credit impairment of financial institutions; our ability to realize amounts on sales of securities on our balance sheet equivalent to their values recorded for accounting purposes; heightened volatility and/or disruption in global capital and credit markets; and Aspen or certain of its Bermuda affiliates becoming subject to income taxes in a jurisdiction outside of Bermuda.

In addition, any estimates relating to loss events involve the exercise of considerable judgment and reflect a combination of ground-up evaluations, information available to date from brokers and cedants, market intelligence, initial tentative loss reports and other sources. The actuarial range of reserves and management’s best estimate represents a distribution from our internal capital model for reserving risk based on our current state of knowledge and explicit and implicit assumptions relating to the incurred pattern of claims, the expected ultimate settlement amount, inflation and dependencies between lines of business. Due to the complexity of factors contributing to losses and the preliminary nature of the information used to prepare estimates, there can be no assurance that Aspen’s ultimate losses will remain within the stated amounts.

The foregoing review of cautionary factors should not be construed as exhaustive; for a more detailed description of these uncertainties and other factors that could impact the forward-looking statements in this press release and other communications issued by or on behalf of Aspen, please see the “Risk Factors” section in Aspen’s Annual Report on Form 20-F for the twelve months ended December 31, 2021, as filed with the SEC, which should be deemed incorporated herein.

The inclusion of forward-looking statements in this press release or any other communication should not be considered as a representation by Aspen that current plans or expectations will be achieved. Aspen undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law.

Basis of Preparation

Aspen has prepared the financial information contained within this financial results press release in accordance with the principles of U.S. Generally Accepted Accounting Principles (“GAAP”).

Non-GAAP Financial Measures

In presenting Aspen’s results, management has included and discussed certain measurements that are considered “non-GAAP financial measures” under SEC rules and regulations. Management believes that these non-GAAP financial measures, which may be defined differently by other companies, help explain and enhance the understanding of Aspen’s results of operations. However, these measures should not be viewed as a substitute for those determined in accordance with GAAP.

Operating income is a non-GAAP financial measure. Operating income is an internal performance measure used by Aspen in the management of its operations and represents after-tax operating results. Operating income includes an adjustment for the change in deferred gain on retroactive reinsurance contracts in order to economically match the loss recoveries under the adverse development cover (“ADC”)/loss portfolio transfer (“LPT”) contracts with the underlying loss development of the assumed net loss reserves for the subject business of 2019 and prior accident years. Operating income also excludes certain costs related to the LPT contract with Enstar that closed in the second quarter of 2022, net foreign exchange gains or losses, including net realized and unrealized gains and losses from foreign exchange contracts, net realized gains or losses on investments and non-operating expenses and income.

Aspen excludes the items above from its calculation of operating income because they are not reflective of underlying performance or the amount of these gains or losses is heavily influenced by, and fluctuates according to prevailing investment market and interest rate movements. Aspen believes these amounts are either largely independent of its business and underwriting process, not aligned with the economics of transactions undertaken, or including them, would distort the analysis of trends in its operations. In addition to presenting net income determined in accordance with GAAP, Aspen believes that showing operating income enables users of its financial information to more easily analyze Aspen’s results of operations in a manner similar to how management analyzes Aspen’s underlying business performance. Operating income should not be viewed as a substitute for GAAP net income.

Underwriting income or loss/ gain or loss is a non-GAAP financial measure. Income or loss for each of the business segments is measured by underwriting income or loss. Underwriting income or loss is the excess of net earned premiums over the sum of losses and loss expenses, acquisition costs and general and administrative expenses. Underwriting income or loss provides a basis for management to evaluate the segment’s underwriting performance.

Adjusted underwriting income or loss is the underwriting profit or loss adjusted for the change in deferred gain on retroactive reinsurance contracts in order to economically match the loss recoveries under the adverse development cover (“ADC”)/loss portfolio transfer (“LPT”) contracts with the underlying loss development of the assumed net loss reserves for the subject business of 2019 and prior accident years. Adjusted underwriting income or loss also excludes certain costs related to the LPT contract with Enstar that closed in the second quarter of 2022. Adjusted underwriting income represents the performance of our business for accident years 2020 onwards, which reflects the underlying underwriting performance of the ongoing portfolio.

Book yield is a non-GAAP financial measure. Book yield is the interest rate earned, at the time of purchase of the fixed income instrument at market value, assuming the bond is held to maturity and all coupon and principal payments are made on schedule.

Loss ratio is a non-GAAP financial measure. Loss ratio is the sum of current year net losses, catastrophe losses and prior year reserve strengthening/(releases) together, loss and loss adjustment expenses, as a percentage of net earned premiums.

Combined ratio is the sum of the loss ratio and the expense ratio. The loss ratio is calculated by dividing losses and loss adjustment expenses by net earned premiums. The expense ratio is calculated by dividing the sum of acquisition costs and general and administrative expenses, by net earned premiums.

Adjusted Combined ratio is the sum of the adjusted loss ratio and the expense ratio. The adjusted loss ratio is calculated by dividing the adjusted losses and loss adjustment expenses by net earned premiums. The expense ratio is calculated by dividing the sum of acquisition costs and general and administrative expenses, by net earned premium.
