*Under Bermuda law there is no concept of "outstanding" share capital, however, to align with U.S. share capital terminology and for the avoidance of doubt, references to "outstanding" with respect to our share capital refer to our "issued" share capital under Bermuda law.*

*References in this report to "U.S. Dollars," "dollars," "$" or "¢" are to the lawful currency of the United States of America, references to "British Pounds," "pounds," "GBP" or "£" are to the lawful currency of the United Kingdom (sometimes referred to herein as the "U.K.") and references to "euros" or "€" are to the lawful currency adopted by certain member states of the European Union (the "E.U."), unless the context otherwise requires.*

***Sompo Merger Transaction***

*On August 27, 2025, Aspen Insurance Holdings Limited ("Aspen") entered into a definitive Agreement and Plan of Merger (the "Merger Agreement"), under which Aspen was to be acquired by a wholly owned indirect subsidiary of Sompo Holdings, Inc. ("Sompo").*

*The Merger Agreement is by and among Aspen, Endurance Specialty Insurance Ltd., a Bermuda exempted company limited by shares and a wholly-owned indirect subsidiary of Sompo ("Parent"), and Ajax Ltd., a Bermuda exempted company limited by shares and a wholly owned subsidiary of Parent ("Merger Sub"). On February 24, 2026 (the "Effective Time"), Merger Sub merged with and into Aspen, with Aspen surviving such merger (the "Merger" and such surviving company, the "Surviving Company") as a wholly-owned subsidiary of Parent and indirect subsidiary of Sompo.*

*As from the Effective Time, the issued Class A ordinary shares, par value $0.001 ("Company Ordinary Shares") of Aspen, were automatically converted into the right to receive an amount in cash equal to US$37.50 per share, without interest. At the Effective Time, the Company notified the New York Stock Exchange (the "NYSE") of the completion of the Merger and requested that trading of the Company Ordinary Shares on the NYSE be suspended and listing on the NYSE be withdrawn, and, as a result, trading of the Company Ordinary Shares on the NYSE was suspended prior to the opening of trading on February 24, 2026. The Company also requested that the NYSE file a notification of removal from listing and/or registration on Form 25 with the U.S. Securities and Exchange Commission ("SEC") with respect to the Company Ordinary Shares to effect the delisting of the Company Ordinary Shares from the NYSE and to deregister the Company Ordinary Shares under Section 12(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). A Form 25 was subsequently filed by the NYSE on February 24, 2026. On March 6, 2026, the Company filed a certification and notice on Form 15 of termination of registration of its Company Ordinary Shares under Section 12(g) of the Exchange Act and a suspension of its duty to file ongoing reports under Sections 13 and 15(d), of the Exchange Act with respect to the Company Ordinary Shares.*

*In addition, each issued (a) 5.625% Perpetual Non-Cumulative Preference Share (the "5.625% PRD Preference Shares"), (b) Depositary Share, each representing a 1/1000th interest in a share of 5.625% Perpetual Non-Cumulative Preference Share (the "5.625% PRE Preference Shares") and (c) Depositary Share, each representing a 1/1000th interest in a share of 7.000% Perpetual Non-Cumulative Preference Shares (the "7.000% PRF Preference Shares" and, collectively with the 5.625% PRD Preference Shares and the 5.625% PRE Preference Shares, the "Preference Shares") of Aspen by virtue of the Merger and without any action on the part of the holder thereof, were automatically converted into a fully paid preference share of the Surviving Company, in each case, entitled to the same dividend and all other preferences and privileges, rights, qualifications, limitations, and restrictions set forth in the applicable certificate of designations of each Preference Share, which such certificate of designation remaining at and following the Effective Time in full force and effect. As from the Effective Time, each issued share of Merger Sub was converted into a common share, par value $1.00, of the Surviving Company.*

&nbsp;&nbsp;&nbsp;&nbsp;**D. Risk Factors** 

*You should carefully consider the following risk factors and all other information set forth in this report, including our consolidated financial statements and the notes thereto. Any of the risks described below could materially and adversely affect our business, operating results or financial condition. The risk factors described below could also cause our actual results to differ materially from those in the forward-looking and other statements contained in this report and other documents that we file with the SEC. The risks and uncertainties described below are not the only ones we face. However, these are the risks we believe to be material as of the date of this report. Additional risks not presently known to us or that we currently deem immaterial may also impair our future business, financial condition or operating results.*

***Introduction***

As with any company which may have certain or all of its securities listed and publicly traded, investing in our securities carries risks. Our risk management strategy is designed to identify, measure, monitor and manage material risks which could adversely affect our financial condition and operating results. We have invested significant resources to develop and maintain appropriate risk management policies and procedures to implement this strategy. Nonetheless, the future business environment is intrinsically uncertain and difficult to forecast and, as a result, our risk management methods may not be successful. For more information on our risk management strategy, refer to Item 4B, "*Business Overview - Risk Management - Risk Management Strategy*."

**Risks Related to Our Business**

***(Re)insurance Risks***

**We may be adversely affected by the occurrence of catastrophes, including weather-related natural disasters, and severe weather events, as well as outbreaks of pandemic or contagious diseases, and we could face unanticipated losses from non-weather related catastrophe events such as war, terrorism and political unrest, cyber attacks, government action that is hostile to commercial interests and from sovereign, sub-sovereign and corporate defaults. These or other unanticipated losses could have a material adverse effect on our financial condition or operating results.**

As part of our insurance and reinsurance operations, we assume substantial exposure to losses resulting from weather-related natural catastrophes, other natural disasters, severe weather events and other catastrophe events. Catastrophes can be caused by various unpredictable events, including, but not limited to, tropical storms, cyclones, hurricanes, winter storms, tornadoes, hailstorms, floods, wildfires, drought, pandemic or contagious disease, volcanic eruptions, earthquakes and tsunamis. For example, we have experienced exposure to Hurricane Helene, Hurricane Milton and the Dubai and German floods in 2024, the California wildfires in early 2025 and other weather-related events.

Our actual ultimate losses from these events may differ materially from initial estimates due to limitations in one or more of the models that we employ and because, initial estimates may be impacted by actual terms and conditions of individual treaties and policies, future loss information to follow from clients and brokers, subrogation considerations, further market intelligence, or any loss reports. In addition, the final settlement of claims associated with certain of these loss events is likely to take place over a considerable period of time and there can be no assurance that our actual losses will not exceed our estimates.

Catastrophes can also be man-made such as acts of war, acts of terrorism and other intentionally destructive acts, including those involving nuclear, biological, chemical or radiological events, cyber-attacks, explosions, infrastructure failures and losses resulting from political instability, government action that is hostile to commercial interests and sovereign, sub-sovereign and corporate defaults. For example, we have experienced exposure to the Russia/Ukraine war (including as a result of a judicial decision by the High Court of the United Kingdom in June 2025) and the collapse of the Francis Scott Key Bridge. In addition, though the current and ongoing conflict in the Middle East, (including the joint U.S.-Israel strikes on Iran that began in late February 2026), Venezuela and other areas of the world have not materially impacted our business to date, it, or similar conflicts in the future, have the potential to escalate into one or more events which could impact our cash flows and results of operations, as well as the insurance and reinsurance industry generally. By way of illustration, the joint U.S.-Israel strikes on Iran that began in late February 2026 have heightened the potential for further conflict with Iran, and we continue to assess our portfolio in order to determine the sources and extent of potential exposure to the ongoing conflict.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Terrorist events could generate greater awareness of the risks multinational corporations face in conflict-prone regions. We closely monitor the amount and types of coverage we provide for terrorism risk under insurance policies and reinsurance treaties. Even in cases where we have deliberately sought to exclude such coverage, there can be no assurance that a court or arbitration panel will interpret policy language or issue a ruling favorable to us. Accordingly, we may not be able to eliminate our exposure to terrorist events and there remains a risk that our reserves will not be adequate to cover such losses should they materialize. Notably, the Terrorism Risk Insurance Program Reauthorization Act of 2019 (the "TRIA Reauthorization") does not provide coverage for reinsurance losses. In addition, we have limited terrorism coverage for exposure to catastrophe losses related to acts of terrorism in the reinsurance that we purchase. Although the TRIA Reauthorization provides benefits in the event of certain acts of terrorism occurring in the United States, those benefits are subject to a deductible and other limitations. The TRIA Reauthorization is due to expire on December 31, 2027.

Our credit and political risk insurance line of business protects insureds with interests in foreign jurisdictions in the event governmental action prevents them from exercising their contractual rights and may also protect their assets against physical damage perils. The insurance provided may include cover for loss arising from expropriation, forced abandonment, license cancellation, trade embargo, contract frustration, non-payment, war on land or political violence (including terrorism, revolution, insurrection and civil unrest).

Our credit and political risk line of business also provides non-payment coverage on specific loan obligations. We insure sovereign non-payment and corporate non-payment as a result of commercial as well as political risk events. The vast majority of the corporate non-payment credit insurance provided is for single-named illiquid risks, primarily in the form of senior bank loans that can be individually analyzed and underwritten. We also aim to avoid terms in our credit insurance contracts which introduce liquidity risk, most notably, in the form of a collateralization requirement upon a ratings downgrade. We also attempt to manage our exposure, by among other things, setting credit limits by country, region, industry and individual counterparty and regularly reviewing our aggregate exposures. However, due to globalization, political instability in one region can spread to other regions. Geopolitical uncertainty regarding a variety of domestic and international matters, such as the U.S. political and regulatory environment, could lead to the potential default by one or more European sovereign debt issuers.

The incidence, severity and magnitude of catastrophes are inherently unpredictable and our losses from such catastrophes have been and can be substantial, and it may be difficult to estimate the amount of loss such an occurrence may generate, including as against preliminary loss estimates. Actual losses from catastrophes may differ materially from preliminary estimates due to limitations in one or more of the applicable models, or because preliminary estimates may not be based on actual terms and conditions of individual treaties and policies expected to be impacted, future loss information expected to follow from clients and brokers, further market intelligence, or any loss reports. In addition, claim payments for catastrophes may take place over a considerable period of time and there can be no assurance that actual losses will not exceed our estimates.

In addition, we expect that increases in the values and concentrations of insured property will increase the severity of such occurrences in the future and that global climate change may increase the frequency and severity of severe weather events, wildfires and flooding. Similarly, changes in global political and economic conditions may increase both the frequency and severity of man-made catastrophe events in the future.

Although we attempt to manage our exposure, including the accumulation of risk exposures, to such events through a multitude of approaches (including geographic diversification, geographic limits, individual policy limits, exclusions or limitations from coverage, purchase of reinsurance, modelling techniques, expansion of supportive collateralized capacity and adherence to Group-level risk tolerance criteria and key risk limits), the availability of these management tools may be dependent on market factors and, to the extent available, may not respond in the way that we expect. In addition, a single catastrophic event could affect multiple geographic zones or the frequency or severity of catastrophic events could exceed our estimates. As a result, the occurrence of one or more catastrophic events or an unusual frequency of smaller events has resulted in, and may in the future result in, substantial volatility in, and may materially adversely affect, our business, financial condition or operating results.

As of January 1, 2026, Aspen's worldwide estimated net Probable Maximum Losses ("PML") catastrophe exposures (net of retrocession and reinstatement premiums) with modelled 1 in 100 year and 1 in 250 year occurrence were $268.9 million and $376.6 million, respectively.

**Global climate change may have an adverse effect on our results of operations, financial condition or liquidity.**

There is widespread consensus in the scientific community that there is a long-term upward trend in global air and sea temperatures that, along with shifting demographic trends in catastrophe exposed regions, has increased the severity and frequency of severe weather events and other natural catastrophes, and is likely to further increase the average economic value of expected losses in the future. Extreme weather events can disrupt business continuity by negatively impacting our infrastructure, systems and processes including, but not limited to, outsourcing arrangements in geographical locations exposed to severe weather events.

A substantial portion of our property coverages may be adversely impacted by climate change. Large-scale climate change could also increase both the frequency and severity of natural catastrophes and our loss costs associated with property damage and business interruption due to storms, floods (including by increasing the risk of coastal flooding in many geographical areas as a result of rising sea levels), wildfires and other weather-related events.

We may also be exposed to liability risks. Liability risks relate to losses or damages suffered by our insureds from physical or transition risks, such as losses stemming from climate-related litigation in liability lines. These risks could arise from management and boards of directors not fully considering or responding to the impacts of climate change, or not appropriately disclosing current and future risks.

In addition, global climate change could give rise to new environmental liability claims in the energy, manufacturing and other industries we serve, as those that have suffered losses seek compensation. For example, a single catastrophic event could affect multiple geographic zones in unprecedented ways or the frequency or severity of such events could exceed our estimates, driving loss costs higher than we could have predicted.

There are also transition risks associated with climate change that could impact our business and investment portfolio. Transition risks arise from the process of adjustment towards a low-carbon economy, including from the proliferation of governmental and regulatory scrutiny related to climate change and greenhouse gases and other factors, including international, federal, state, and local regulations, scrutiny, and enforcement and societal changes. A range of factors influence this adjustment, including climate-related developments in policy and regulation, the emergence of disruptive technology or business models, shifting sentiment and societal preferences, or evolving evidence, frameworks and legal interpretations. Additionally, demand and supply of insurance and reinsurance coverage could be negatively impacted to the extent that carbon-intensive businesses are impacted by this transition, and certain claims and losses related to those industries could increase, either of which could have a material negative effect on our business and results of operations.

Catastrophic events could result in increased credit exposure to reinsurers and other counterparties we transact business with, declines in the value of investments we hold and significant disruptions to our physical infrastructure, systems and operations. Climate change-related risks may also specifically adversely impact the value or risk characteristics of the securities that we hold and may ultimately impact our asset-liability management practices.

While we have invested heavily and introduced procedures to understand the influence of climate change, such as scenario analysis and the ongoing review of assumptions in pricing models and risk selection, given the scientific uncertainty of predicting the effect global climate change on the frequency and severity of natural catastrophes and the limitations of predictive tools, we may not be able to adequately model the associated exposures and potential costs or losses in connection with such future weather events, or other natural catastrophes, and our risk assessments may not accurately reflect shifting environmental and climate related risks. This could have a material adverse effect on our business, financial condition or operating results.

**The effects of emerging claim trends and social inflation on our business are uncertain.**

As industry practices and legislative, regulatory, judicial, socio-economic, financial, technological and other environmental conditions evolve, new and unforeseen issues relating to claims liabilities and insurance coverage may arise. These developments may adversely affect our business by extending coverage beyond our underwriting intent or by increasing the frequency and severity of claims.

Legislative, regulatory, judicial or societal developments may also impose new obligations on insurers and reinsurers, including in connection with climate change, that could expand coverage beyond intended contractual, terms or result in higher claim frequency or severity than anticipated, as described in "—Global climate change may have an adverse effect on our results of operations, financial condition or liquidity."

In addition, increasing fraud and abusive practices at the primary claims level, together with social inflation, including more aggressive litigation strategies by the plaintiffs' bar, expanded theories of liability, increasing reliance on third-party litigation financing, and rising settlement values and jury awards, have affected our loss experience and reserving practices and may continue to do so in unpredictable ways. These trends may emerge or accelerate after insurance or reinsurance contracts have been issued, making their impact difficult to anticipate at the time of underwriting.

We regularly review the potential effects of these developments on our loss reserves to ensure our reserving reflects the most current available information. However, because many of these risks evolve over time and claims may take years to resolve, the ultimate liabilities under our insurance and reinsurance contracts may not be known for many years after the policies are issued.

**We may be adversely affected by economic and claims inflation** 

Our underwriting results, loss reserves and investment income, are susceptible to the effects of economic inflation because premiums are established before the ultimate amounts of losses and loss adjustment expenses are known. Although we consider inflation in establishing premium rates and policy terms, actual inflation may differ from our assumptions. If inflation exceeds our expectations, premiums may prove inadequate and risks we insure or reinsure may be underpriced.

In addition, the costs associated with insured losses—often referred to as claims inflation—may increase at rates that exceed general economic inflation. Claims inflation may be driven by increases in the cost of construction materials, automobile parts, medical care, skilled labor, and litigation and claims-handling expenses, as well as supply chain disruptions and other industry-specific factors. These increases may result in higher claim severity and may adversely affect our underwriting results.

Loss reserves reflect assumptions regarding the ultimate cost to settle claims. If inflation causes the cost of claims to increase beyond the levels assumed in our reserves, we may be required to strengthen reserves, which would reduce net income in the period in which the deficiency is identified, and could have a material adverse effect on our results of operations or financial condition. Because many claims, particularly in longer-tail lines of business, may take years to resolve, the full effects of inflation on our reserves may not be known for extended periods.

Economic inflation may also contribute to increased settlement values and jury awards, particularly when combined with social inflation, including evolving liability theories and more aggressive litigation practices. Changes in inflation expectations may also influence interest rates, and financial market conditions. Rising interest rates may reduce the market value of our fixed-income securities and other interest-sensitive investments, which could result in unrealized investment losses, although higher interest rates may increase reinvestment yields over time.

Although inflation, moderated in certain economies following the elevated levels experienced in recent years, inflationary pressures may persist or increase due to supply chain disruptions, labor shortages, geopolitical developments, fiscal and monetary policy, and other macroeconomic conditions. Sustained or renewed inflation could adversely affect the adequacy of our pricing and reserves and may have a material adverse effect on our results of operations, financial condition, or liquidity.

**Our results may fluctuate as a result of many factors, including cyclical changes in the reinsurance and insurance industries.**

Historically, the performance of the property and casualty reinsurance and insurance industries has tended to fluctuate in cyclical periods of price competition and excess underwriting capacity, followed by periods of high premium rates fueled by shortages of underwriting capacity. Although an individual (re)insurance company's performance is dependent on its own specific business characteristics, the profitability of most property and casualty (re)insurance companies tends to follow this market cycle. Further, this cyclical market pattern can be more pronounced in the reinsurance market in which Aspen Re competes and in the excess and surplus market in which Aspen Insurance primarily competes than in the standard admitted insurance market. In addition, compared with historical cyclical periods, a cycle of increased price competition related to excess underwriting capacity may continue for a prolonged period of time as new and existing reinsurance and insurance market participants and products continue to enter the (re)insurance markets. Unfavorable market conditions may affect the ability of our (re)insurance subsidiaries to write business at rates they consider appropriate relative to the risk assumed. If we cannot write business at appropriate rates, our business would be significantly and adversely affected. We believe the market currently remains attractive; however, there is softening occurring primarily in short tail lines of business due to benign catastrophe activity. Our business may be significantly and adversely affected if these conditions do not persist.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

When premium rates are high and there is a shortage of capacity in the standard admitted insurance market, growth in the excess and surplus market can be significantly more rapid than growth in the standard insurance market. Similarly, when there is price competition and excess underwriting capacity in the standard insurance market, many customers that were previously driven into the excess and surplus market may return to the standard insurance market, exacerbating the effects of price competition.

Demand for reinsurance is influenced significantly by underwriting and investment results in both the standard insurance and the excess and surplus markets and market conditions. The supply of reinsurance is related to prevailing prices, the levels of insured losses and the levels of reinsurance industry available capital, among other factors. These in turn may fluctuate in response to changes in rates of return on investments being earned in the reinsurance industry. In addition, the supply of reinsurance is affected by a reinsurer's confidence in its ability to accurately assess the probability of expected underwriting outcomes, particularly with respect to catastrophe losses.

Since cyclicality is due in large part to the collective actions of insurers and reinsurers, general economic conditions and the occurrence of unpredictable events, we cannot predict the timing or duration of changes in the market cycle. These cyclical patterns cause our revenues and net earnings to fluctuate, which could have a material adverse effect on our financial condition or operating results.

**Our reinsurers may not reimburse us for claims on a timely basis, or at all, or raise allegations with respect to specific contractual provisions, which may materially and adversely affect our business, results of operations and financial condition.**

The reinsurance contracts that we enter into to help manage our risks require us to pay premiums to the reinsurance carriers who will in turn reimburse us for a portion of covered policy claims. In many cases, a reinsurer will be called upon to reimburse us for policy claims many years after we have paid reinsurance premiums to the reinsurer. Although reinsurance makes the reinsurer liable to us to the extent the risk is transferred or ceded to the reinsurer, it does not relieve us (the ceding insurer) of our primary liability to our policyholders. Our current reinsurance program is designed to limit our financial risk. However, our reinsurers may not pay claims we incur on a timely basis, or they may not pay some or any of these claims at all. For example, reinsurers may default in their financial obligations to us in the event of insolvency, insufficient liquidity, operational failure, political and/or regulatory prohibitions, fraud (including in relation to any collateral fraudulently provided), dispute views on loss quantum, assert defenses based on agreement wordings or the principle of utmost good faith, asserted deficiencies in the documentation of agreements, dispute or allege non-compliance with certain contractual provisions or other reasons. Any disputes with reinsurers regarding coverage under reinsurance contracts could be time-consuming, costly and may not be resolved successfully. These risks could cause us to incur increased net losses, and, therefore, adversely affect our business, results of operations and financial condition.

**The reinsurance that we purchase and capital market transactions that we enter into may not always be available on favorable terms or we may choose to retain a higher proportion of particular risks compared to previous years.**

From time to time, market conditions have limited, and in some cases prevented, insurers and reinsurers from obtaining the types and amounts of reinsurance that they consider adequate for their business needs. Accordingly, we may not be able to obtain our desired amount of reinsurance or retrocession protection on terms that are acceptable to us from entities with a satisfactory credit rating or which is collateralized. Even if such capacity is available, we may also choose to adjust our underwriting activities or retain a higher proportion of particular risks than in previous years due to pricing, terms and conditions or strategic emphasis. We may also seek alternative means of transferring risk, including expanded participation via our ACM platform in alternative reinsurance structures. These solutions may not provide commensurate levels of protection compared to traditional retrocession and transactions with the capital markets are subject to investor appetite and market conditions, including when compared to the terms and yield opportunities of alternative investment opportunities. Our inability to obtain adequate reinsurance or other protection for our own account at favorable prices and on acceptable terms could have a material adverse effect on our business, operating results and financial condition.

**A material proportion of our business relies on the assessment and pricing of individual risks by third parties.**

For certain lines of business, we authorize managing general agents, coverholders, producers or other agents to write business or deal with claims on our behalf within authorities and limitations determined by us. We rely on the controls of these agents to underwrite business or deal with claims within authorities and limitations. Although we have contractual or other legal protections, and we monitor such business on an ongoing basis, our monitoring efforts may not be adequate or such third parties may exceed their authorities, act outside their limitations or otherwise breach obligations owed to us. There is also the risk that we may be held responsible for obligations that arise from the acts or omissions of third parties if they are deemed to have acted on our behalf. In addition, our agents, our insureds or other third parties may commit fraud or otherwise breach their obligations to us or otherwise fail to comply with applicable laws and regulations (including but not limited to economic and trade sanctions, anti-bribery and anti-corruption laws and anti-money laundering laws). Our regulatory standing, financial condition and results of operations may be materially adversely affected by any of these issues.

While we conduct underwriting, financial, claims and information technology and other due diligence reviews prior to entering into these arrangements and apply rigorous standards in the selection and ongoing monitoring of these counterparties, there is no assurance they have provided us accurate or complete information to assess the risk or that they can manage effectively their own risks. The counterparties are also subject to the same global increase in cyber incidents, including ransomware facing the (re)insurance industry, and we cannot offer assurances that these counterparties have sufficient technical and organizational controls to mitigate these risks. Consequently, we assume a degree of credit and operational risk of those parties, and a material failure to manage their risks may result in material losses or damage to us. Our financial condition and results of operations could be materially adversely affected by any one of these issues.

Our reliance on third-party assessment and pricing of individual risk extends to our reinsurance treaty and subscription-based business. Similar to other reinsurers, we do not separately evaluate each of the individual risks assumed under most reinsurance treaties. We are therefore largely dependent on the original underwriting decisions made by ceding companies. We are subject to the risk that the ceding companies may not have adequately evaluated the risks to be reinsured and that the premiums ceded to us may not adequately compensate us for the risks we assume and the losses we may incur. As a result of this reliance on ceding companies and "lead" markets for subscription business (where pricing and terms may be set by other insurance or reinsurance participants where Aspen adopts a "follow" position), our operating results and financial condition may be materially adversely affected.

**The failure of any risk management and loss limitation methods we employ could have a material adverse effect on our financial condition and operating results.**

We employ various risk management and loss limitation methods. We seek to manage our loss exposure by maintaining disciplined underwriting processes designed to guide the pricing, terms and acceptance of risk. These processes, which may include the use of pricing models, are intended to ensure that premiums received are sufficient to cover the expected levels of attritional losses and a contribution to the cost of catastrophes and large losses, where necessary. We also seek to mitigate our loss exposure by writing a number of our insurance and reinsurance contracts on an excess of loss basis, such that we only pay losses that exceed a specified retention. We also seek to limit certain risks, such as catastrophes and political risks, by geographic diversification. Geographic zone limitations involve significant underwriting judgments, including the determination of zone boundaries and the allocation of policy limits to zones. In the case of proportional (also known as pro rata) property reinsurance treaties, we often seek per occurrence limitations or loss and loss expense ratio caps to limit the impact of losses from any one event, although we may not be able to obtain such limits in certain markets. Purchasing reinsurance is another loss limitation method we employ.

There are inherent limitations in all of these actions and it is possible that an event or series of events could result in loss levels that could have an adverse effect on our financial condition and results of operations. It is also possible that our controls and monitoring efforts may be ineffective, permitting one or more underwriters to exceed their underwriting authority and cause us to (re)insure risks outside the agreed upon guidelines or that losses could manifest themselves in ways that we do not anticipate and that our risk mitigation strategies are not designed to address. Additionally, various provisions in our policies, such as limitations or exclusions from coverage or choice of forum negotiated to limit our risk may not be enforceable in the manner we intend, As a result, one or more natural catastrophes and/or terrorism or other events could result in claims that substantially exceed our expectations, which could have a material adverse effect on our financial condition or operating results.

In January 2022, Aspen Holdings and certain of its subsidiaries entered into a loss portfolio transfer reinsurance agreement ("LPT") with a subsidiary of Enstar Group Limited, Cavello Bay Reinsurance Limited ("Cavello Bay," referred to herein as "Enstar" unless otherwise expressly identified). See "*Additional Information—Material Contracts——Loss Portfolio Transfer ("LPT") Agreement*" for additional information. The LPT represents a repositioning of the adverse development cover previously entered into between the Company and Enstar in March 2020. The LPT transaction successfully closed in May 2022. The nature and structure of the LPT present certain risks to us, including risks related to litigation, claims, marketing, credit and reserving, as well as general management risks and the risk of differences in interpretation between the parties of the availability, scope and terms of coverage, all or any of which may have an uncertain impact across multiple operational functions and on our business generally. For further information, please refer to Item 4, "*Information on the Company" – "Legal Proceedings*."

**Our financial condition and operating results may be adversely affected if actual claims exceed our loss reserves.**

Our operating results and financial condition depend on our ability to accurately assess the potential losses associated with the risks that we (re)insure. Establishing an appropriate level of loss reserves is an inherently uncertain process and requires a considerable amount of judgment. There are many factors that would cause our reserves to increase or decrease, which include, but are not limited to, changes in claim severity, changes in the expected level of reported claims, judicial action changing the scope and/or liability of coverage, changes in the legislative, regulatory, social and economic environment and unexpected changes in loss inflation. To the extent actual claims exceed our expectations, we will be required to recognize the less favorable experience immediately which could cause a material increase in our provisions for liabilities and a reduction in our profitability, including operating losses and reduction of capital. Conversely, if our reserving estimates are too conservative, it could impede our ability to grow our business.

We cannot estimate losses from natural and man-made catastrophic events, such as hurricanes, fires, earthquakes or pandemic events, using traditional actuarial methods. The magnitude and complexity of losses associated with certain of these events inherently increase the level of uncertainty and, therefore, there is a significant level of management judgment involved in arriving at loss reserve estimates. As a result, actual losses for these events may ultimately differ materially from current estimates.

While we believe that our historical experience is capable of providing us with meaningful actuarial indications, estimates and judgments for new (re)insurance lines of business are more difficult to make than those made for more mature lines of business because we have more limited historical information through December 31, 2025. A significant portion of our current loss reserves is in respect of incurred but not reported ("IBNR") reserves. This IBNR reserve is based almost entirely on estimates involving actuarial and statistical projections of our expectations of the ultimate loss and claims handling expenses. In addition to limited historical information for certain lines of business, we utilize actuarial models as well as historical insurance industry loss development patterns to establish loss reserves. Changes in the assumptions used by these models or by management could lead to an increase in our estimate of ultimate losses in the future. In addition, there may be significant reporting lags between the occurrence of the insured event and the time it is reported to the insurer and additional lags between the time of reporting and final settlement of claims. In addition, the estimation of loss reserves is more difficult during times of adverse economic and market conditions due to unexpected changes in behavior of claimants and policyholders, including an increase in fraudulent reporting of exposures and/or losses, reduced maintenance of insured properties or increased frequency of small claims. Accordingly, actual claims and claim expenses paid may deviate, perhaps substantially, from our reserve estimates, which could materially adversely affect our financial results.

Following the acquisition of the Company by Sompo, we are reviewing our reserving methodologies and assumptions across the Company, particularly since the Company applies US GAAP and Sompo has adopted IFRS 17. Such review may result in changes to reserve estimates, including potential adjustments to reserves, even if prior estimates were reasonable at the time they were established. Any such changes would be recognized in the period in which they are determined and could adversely affect our results of operations, financial condition, equity, or key performance metrics in those periods.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Only reserves applicable to losses and loss adjustment expenses incurred up to the reporting date may be set aside in our financial statements, with no allowance for future losses. Our estimates of reserves for losses and loss expenses also include assumptions about future payments for settlement of claims and claims-handling expenses, such as medical treatment, awards for pain and suffering and litigation costs. We write casualty business in certain jurisdictions and other territories where claims inflation has for many years run at higher rates than general inflation. To the extent economic or social inflation, such as through outsized court awards, particularly in the United States, causes these costs to increase above reserves established for these claims, we will be required to increase our loss reserves with a corresponding reduction in our net income in the period in which the deficiency is identified, which could materially adversely affect our financial results. (see further at "*The effects of emerging claim and coverage issues in our business and social inflation are uncertain" and "We may be adversely impacted by economic inflation*").

**Increases in the frequency and severity of cyber attacks on our policyholders could adversely affect our financial condition and operating results.**

The cybersecurity threat landscape is evolving, and there is a risk that increases in the frequency and severity of cyber-attacks on our policyholders could adversely affect our financial condition and operating results. This risk is also dependent on our policyholders' cybersecurity defenses, and our issuance of policy terms which respond to the evolving threat landscape. Moreover, irrespective of the clarity and inclusiveness of policy language, there can be no assurance that a court or arbitration panel will not limit enforceability of policy language or otherwise issue a ruling adverse to us. In addition, our exposure to cyber-attacks on our policyholders includes exposure to silent cyber risks, meaning risks and potential losses associated with policies where cyber risk is not specifically included nor excluded in the policies. Even in cases where we attempt to exclude losses from cyber-related risks, there can be no assurance that a court or arbitration panel will interpret policy language, or otherwise issue a ruling, favorable to us.

***Market and Liquidity Risks***

**Our investments are subject to interest rate, credit, and real estate related risks, which may adversely affect our net income and may adversely affect the adequacy of our capital.**

We invest the net premiums we receive until such time as we pay out losses and/or until they are made available for distribution to ordinary and preferred shareholders, pay interest on or redeem debt and preferred shares, or otherwise use such net premiums for general corporate purposes. Investment income comprises a substantial portion of our Group income. We therefore are exposed to significant financial and capital market risks, including changes in interest rates, credit spreads, credit defaults, foreign exchange rates, market volatility impacting the valuation of our investments, the performance of the economy in general, and other factors outside our control. The impact of geopolitical tension, such as a deterioration in the bilateral relationship between the United States and China and other jurisdictions, or an escalated conflict between Russia and Ukraine, or within the Middle East (including the joint U.S.-Israel strikes on Iran that began in late February 2026), including any resulting sanctions, export controls or other restrictive actions that may be imposed by the United States and/or other countries against governmental or other entities also could lead to disruption, instability and volatility in the global markets, which may have an impact on our investments across negatively impacted sectors or geographies.

A significant portion of our investments could be influenced by changes in interest rates across a number of geographies. Interest rates are highly sensitive to many factors, including fiscal and monetary policies of major economies, inflation, economic and political conditions and other factors outside our control. Changes in interest rates can negatively affect net investment income in that, in a declining interest rate environment, investments in fixed maturities and short-term investments (fixed maturity portfolio) would earn interest income at lower rates. In a declining interest rate environment, the market value of our fixed income portfolio would increase. However, in a rising interest rate environment, the market value of our fixed income portfolio will decline, which we experienced in 2022 and 2023. Furthermore, depending on our liquidity needs and investment strategy, we may liquidate investments prior to maturity at a loss in order to cover liabilities as they become due or to invest in other investment opportunities that have better expected longer term profitability.

Our fixed maturity portfolio is primarily invested in high quality, investment grade securities, including collateralized loan obligations ("CLOs"). However, we invest a portion of the portfolio in securities that are below investment grade. We also invest a portion of our portfolio in other investments such as unrated private fixed and floating rate investments, and other specialty asset classes. These securities generally pay a higher rate of interest or return and may have a higher degree of credit or default risk. These securities may also be less liquid in times of economic weakness or market disruptions. Within these investments, we invest directly and indirectly in private loans and real estate assets, which, as described more fully below, are subject to additional risks.

**Our business may be negatively impacted by adverse developments affecting the financial services industry, such as actual events or concerns involving liquidity, defaults or non-performance by financial institutions and the potential contagion impact to, and resulting stress on, the financial services sector generally.**

Actual events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds or other similar risks, have in the past and may in the future lead to market-wide liquidity problems. Such events could include the failure of financial institutions or adverse developments affecting the Lloyd's market.

Although we assess our banking relationships as we believe necessary or appropriate, we cannot guarantee that the banks or other financial institutions that hold our funds will not experience liquidity issues or failures in the future. We cannot predict whether such events may occur in the future, or what impact such events would have on the financial services sector and any heightened macroeconomic or political instability that may follow, including any regulatory changes. This could include impacts on the availability of our existing cash and cash equivalents or market value of our investments, or those of our trading partners such as regional program managers. In addition, we could be exposed to losses through our underwriting segments, including, but not limited to, within our financial and professional insurance portfolio.

In addition, widespread investor concerns regarding the U.S. or international financial systems could result in less favorable commercial financing terms, including higher interest rates or costs and tighter financial and operating covenants, or systemic limitations on access to credit and liquidity sources, thereby making it more difficult for us to acquire financing on acceptable terms or at all. Any decline in available funding or access to our cash and liquidity resources could, among other risks, adversely impact our ability to meet our operating expenses, financial obligations or fulfill our other obligations, or result in breaches of our financial and/or contractual obligations. Any of these impacts, or any other impacts resulting from the factors described above or other related or similar factors not described above, could have material adverse impacts on our liquidity and our current and/or projected business operations and financial condition and results of operations.

Our business may be adversely impacted by these developments in ways that we cannot predict at this time, and we cannot guarantee that we will be able to avoid negative consequences directly or indirectly from any failure of one or more banks or other financial institutions. Any of the foregoing could have a material adverse effect on our business, financial condition, liquidity and results of operations. In addition, the foregoing may have the effect of triggering or intensifying many of the risks described elsewhere in this "Risk Factors" section.

**Our investments in private, secured commercial mortgage loans ("CML") and private, secured middle market loans ("MML") are subject to credit risk, market risk, servicing risk, loss from catastrophic events and other risks, which could diminish the value that we obtain from such investments.**

As of December 31, 2025, a portion of our total invested assets was invested in private, secured CMLs, and in private, secured MMLs and other private debt. The CML and MML portfolios that we hold face both default and delinquency risk. An increase in the delinquency or default rate of our CML/MML portfolios, which may limit substantially the ability of the borrower or issuer of such securities to make payments to the loan holders, reducing the value of those loans or securities or require workouts or restructurings, or geographic or sector concentration within our CML/MML portfolios, may, in either or both cases, impact the value of our investments in such CMLs or MMLs and materially and adversely impact our financial condition and results of operations. Any failure to manage these risks effectively could materially and adversely affect our financial condition and results of operations. In general, any significant weakness in the broader macro economy or significant problems in a particular real estate market or corporate market may cause a decline in the value of the real estate market and corporate assets securing the loans in that market, thereby increasing the risk of delinquency, default and foreclosure. Additionally, the carrying value of the CML and MML portfolios may change from time to time or may not be recoverable. This could, in turn, have a material adverse effect on our credit loss experience. In addition, as with all investments, such CMLs or MMLs may be subject also to third-party litigation risk, to which a member of the Aspen Group may be named as a party from time to time. Any or a combination of the scenarios described above could adversely affect our business, operating results or financial condition.

As at December 31, 2025, the Company had an allocation of 0.6% to CMLs and MMLs.

For more information on our CML and MML investments, which we also refer to as "privately-held investments," refer to "Note 4—*Investments*" to our audited consolidated financial statements.

**A portion of our invested assets are relatively illiquid and we may fail to realize profits from these assets for a considerable period of time, or lose some or all of the principal amount we invest in these assets if we are required to sell our invested assets at a loss to meet our insurance, reinsurance or other obligations.**

We seek to configure our investment portfolio to provide and maintain sufficient liquidity to support our insurance, reinsurance and other obligations. However, in order to provide necessary long-term returns and to achieve our strategic goals, at times a portion of our assets may be relatively illiquid. A portion of our investments are in securities that are not publicly traded or that otherwise lack liquidity, such as our privately-held fixed maturity and floating rate securities, below investment grade securities, and alternative investments.

We record our relatively illiquid types of investments at fair value. If we were forced to sell some or all of these assets, there can be no assurance that we would be able to sell them for the values at which such assets are recorded and we might consequently sell these assets at significantly lower values to the recorded value. When we hold a security or position, it is vulnerable to price and value fluctuations and may experience losses if we are unable to sell or hedge the position. Thus, it may be impossible or costly for us to liquidate positions rapidly in order to meet unexpected obligations. This potential mismatch between the liquidity of our assets and liabilities could have a material and adverse effect on our business, financial condition, results of operations and cash flows.

We also invest in CLOs and control over the CLOs in which we invest is exercised through collateral managers, who may take actions that could adversely affect our interests, and we may not have the right to direct collateral management. There may also be less information available to us regarding the underlying debt instruments held by CLOs than if we had invested directly in the debt of the underlying companies. Our investments in CLOs are also subject to liquidity risk as there is a less liquid market for CLOs (when compared, by way of illustration, to U.S. Government Treasuries). Accordingly, we may suffer unrealized depreciation and could incur realized losses in connection with the sale of our CLO investments.

**Volatility and uncertainty in general economic conditions and in financial and mortgage markets could adversely impact our business prospects, operating results, financial position and liquidity.**

Over the past few years, due to significant economic and social inflation, the rapid and strong rise in interest rates, and ongoing uncertainty with respect thereto, the possibility of a recession, ongoing uncertainty as to the emergence of potential new pandemics and other global macroeconomic and geopolitical tensions and instability, global financial markets have been characterized by volatility and uncertainty. Unfavorable economic conditions could increase our funding costs, limit our access to the capital markets or make credit harder to obtain. Uncertainties in the financial and mortgage markets may also affect our counterparties which could adversely affect their ability to meet their obligations to us.

Deterioration or volatility in the financial markets or general economic and political conditions could result in a prolonged economic downturn or trigger another recession and our operating results, financial position and liquidity could be materially and adversely affected. Further, unfavorable economic conditions could have a material adverse effect on certain or any of the lines of business we write, including, but not limited to, credit and political risks and professional liability risks.

We provide credit reinsurance to mortgage guaranty insurers and commercial credit insurers. We are exposed to the risk that losses from mortgage insurance materially exceed the net premiums that are received to cover such risks, which may, subject to liability caps, result in operating and economic losses to us. Mortgage insurance underwriting losses that have the potential to exceed our risk appetite are associated with the systemic impacts of severe mortgage defaults, driven by large scale economic downturns and high unemployment.

Such matters may have the effect of triggering or intensifying many of the risks described elsewhere in this "Risk Factors" section.

**The determination of the amount of allowances and impairments taken on our investments is highly subjective and could materially impact our operating results or financial position.** 

We perform a detailed analysis each reporting period end to assess movements in the fair values of available for sale debt securities in accordance with applicable accounting guidance regarding the recognition and presentation of current expected losses. The process of determining an allowance for available for sale securities requires judgment and involves analyzing many factors. For additional information regarding this process, and the changes to the applicable accounting policies, refer to "Note 2(c)—"*Basis of Presentation and Significant Accounting Policies —Accounting for Investments, Cash and Cash Equivalents*", and "Note 2(m)—"*Basis of Presentation and Significant Accounting Policies—Accounting Pronouncements*" to our audited consolidated financial statements. Assessing the accuracy of the allowances reflected in our financial statements is inherently uncertain given the subjective nature of the process. Furthermore, additional impairments may need to be taken or allowances provided in the future with respect to events that may impact specific investments. While our current allowance is not material, the current allowance may not be indicative of future impairments or allowances. Thus, future material impairments themselves or any error in accurately accounting for them may have a material adverse effect on our financial condition or results of operations.

**Our financial condition or operating results may be adversely affected by currency fluctuations that we may not be effective at mitigating.**

Our reporting currency is the U.S. dollar. However, a significant portion of our operations is conducted outside the United States in a variety of foreign (non-U.S.) currencies. Accordingly, we are subject to legal, economic and market risks associated with devaluations and fluctuations in currency exchange rates. Our assets and liabilities denominated in foreign currencies are therefore exposed to changes in currency exchange rates, which may be material. The principal currencies creating foreign exchange risk are the British Pound, the Euro, the Swiss Franc, the Australian Dollar, the Canadian Dollar and the Singapore Dollar. At December 31, 2025, 24.9% of gross written premiums were denominated in non-U.S. currencies. We employ various strategies, including the use of foreign exchange forward contracts and other derivative financial instruments, to manage our exposure to foreign currency exchange risk. To the extent that these exposures are not fully offset or hedged, or the hedges are ineffective at mitigating adverse effects, our financial results and condition may be negatively impacted by fluctuations in foreign currency exchange rates.

***Credit Risks***

**Our operating results may be adversely affected by the failure of policyholders, brokers or other intermediaries or reinsurers to honor their payment obligations.** 

In accordance with industry practice, we generally pay amounts owed on claims under our insurance and reinsurance contracts to brokers, coverholders, agents or other third parties and these parties, in turn, pay these amounts to the policyholders that purchased insurance and reinsurance from us. If such a third party fails to make such a payment, we may be liable to the policyholder for the deficiency because of local laws or contractual obligations. Likewise, when the policyholder pays premiums for policies to such third parties for payment to us, these premiums are generally considered to have been paid and, in most cases, the policyholder will no longer be liable to us for those amounts whether or not we have actually received the premiums. Consequently, we assume a degree of credit risk associated with brokers and other agents or representatives with respect to most of our (re)insurance business.

In addition, adverse economic conditions, operational failure, delay due to litigation, bad faith and fraud, bankruptcy, liquidity, distressed financial conditions, sanctions or the general effects of economic recession may increase the risk that policyholders may not pay a part of, or the full amount of, premiums owed to us despite an obligation to do so. The terms of our contracts or local law may not permit us to cancel our insurance even if we have not received payment. For further details, please refer to Item 4, "*Information on the Company" – "Legal Proceedings*."

We purchase reinsurance for our own account in order to mitigate the effect of certain large and multiple losses upon our financial condition. Our reinsurers or capital market counterparts are dependent on their ratings in order to continue to write business and some have suffered downgrades in ratings in the past as a result of their exposures. Our reinsurers or capital market counterparties may also be affected by adverse developments in the financial markets, which could adversely affect their ability to meet their obligations to us. Insolvency of these counterparties, their inability to continue to write business or reluctance to make timely payments under the terms of their agreements with us could have a material adverse effect on us because we remain liable to our insureds or cedants in respect of the reinsured risks.

Although we have not experienced any material credit losses in recent years, an increased inability of our policyholders to meet their obligations to us, particularly during periods of economic uncertainty, could have a material adverse effect on our financial condition and results of operations.

***Strategic Risks***

**Competition and consolidation in the (re)insurance industry could reduce our growth and profitability.**

Insurance and reinsurance markets are highly competitive. We compete on an international and regional basis with major U.S., Bermuda, European and other international (re)insurers and underwriting consortia and syndicates, including syndicates at Lloyd's, some of which have greater financial, marketing and management resources than we do. We also compete with new companies that continue to be formed to enter the (re)insurance markets. In addition, capital market participants have created alternative products that are intended to compete with reinsurance products. We are seeing an increase in alternative capital inflows in the (re)insurance market for both property and casualty lines in concurrence with capital growth at traditional competitors due to favorable underwriting results. This increase in the supply of capital has led to softening conditions in short tail lines of business. We have sought to address this risk by developing our own capital markets capability through ACM. See further information on associated risks described elsewhere in this "*Risk Factors"* section, including *"—We are exposed to risks in connection with our management of alternative reinsurance platforms on behalf of investors in any entities ACM manages or could manage in the future.*"

There has also been a large volume of merger and acquisition activity in the (re)insurance sector in recent years which may continue and we may experience increased competition as a result of that consolidation with consolidated entities having enhanced market power. As the (re)insurance industry consolidates, competition for customers will become more intense and the importance of acquiring and properly servicing each customer will become greater.

Increased competition could result in fewer submissions, lower premium rates, less favorable policy terms and conditions and greater expenses relating to customer acquisition and retention, which could have a material adverse impact on our operating results or financial condition.

**Our Operating Subsidiaries are rated and our Lloyd's business benefits from a rating by one or more of A.M. Best and S&P and a decline in any of these ratings could adversely affect our standing among brokers and customers and cause our premiums and earnings to decrease, or may otherwise result in an adverse effect on our business, financial condition and operating results.** 

Ratings have become an increasingly important factor in establishing the competitive position of insurance and reinsurance companies and will also impact the cost and availability of capital to an insurance company. Rating agencies represent independent opinions of the financial strength of insurers and reinsurers and their ability to meet policyholder obligations. Our existing ratings by A.M. Best and S&P represent an important consideration in maintaining customer confidence in us and in our ability to market insurance products. Rating organizations regularly analyze the financial performance and condition of insurers and some policyholders are required to obtain insurance coverage from insurance companies that have an "A-" (Strong) rating or higher.

On February 24, 2026, following the successful completion of Sompo's acquisition of Aspen Insurance Holdings Limited, S&P upgraded the financial strength and issuer credit ratings of Aspen Bermuda, AAIC and Aspen UK to "A" from "A-, while the long-term issuer credit rating of Aspen Holdings was upgraded to "BBB+" from "BBB." Issue ratings on the Company's senior debt moved to 'BBB' from 'BBB-' and on the Company's preference shares to 'BBB-' from 'BB+'. All ratings were removed from CreditWatch, where they had been placed with positive implications on September 1, 2025. The outlook on all ratings is positive.

On February 27, 2026, A.M. Best announced that it has maintained the under review with positive implications status for the Financial Strength Rating of "A" (Excellent) and the Long-Term Issuer Credit Rating of "a" (Excellent) of Aspen Bermuda, Aspen UK, Aspen Specialty and AAIC. The under review with positive implications status reflects the potential financial and operational benefits to Aspen and its subsidiaries from being part of a significantly larger and financially stronger insurance group. The ratings will remain under review pending AM Best's assessment of Sompo's future business plans for the Aspen entities. Aspen Lloyd's benefits from the Lloyd's market financial strength rating of "A+" (Superior) with a stable outlook by A.M. Best and "AA-" (Very Strong) with a stable outlook by S&P.

The ratings of our Operating Subsidiaries are subject to periodic review by, and may be placed on credit watch, revised downward or revoked at the sole discretion of, A.M. Best or S&P. For more information, see "*Business—Ratings*." These ratings are intended to measure a company's ability to repay its obligations and are based upon criteria established by the rating agencies. Ratings may be solicited or unsolicited.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

The rating agencies with whom we maintain an interactive rating relationship for the purposes of the solicited ratings, currently A.M. Best and S&P, continuously evaluate us to confirm that we continue to meet the criteria of the rating assigned to us. Our ratings may be revised downward or revoked at the sole discretion of the rating agencies at any time. The financial strength ratings assigned by rating agencies to insurance or reinsurance companies are based upon factors relevant to cedants, which include factors not entirely within our control, including factors impacting the financial services, insurance and reinsurance industries generally. Financial strength ratings by rating agencies are not ratings of securities or recommendations to buy, hold or sell any security.

If our Operating Subsidiaries' or if Lloyd's ratings are reduced from their current levels by either A.M. Best or S&P, our competitive position in the (re)insurance industry might suffer and it may be more difficult for us to market our products, expand our (re)insurance portfolio and renew our existing (re)insurance policies and agreements. A rating downgrade may also require us to establish trusts or post letters of credit for ceding company clients and could trigger provisions allowing some clients to terminate their (re)insurance contracts with us. Some contracts also provide for the return of premium to the ceding client in the event of a rating downgrade. It is increasingly common for our reinsurance contracts to contain such terms. Whether a cedant would exercise any of these rights could depend on various factors, such as the reason for and the extent of such downgrade, the prevailing market conditions and the pricing and availability of replacement reinsurance coverage. A downgrade could result in a substantial loss of business as ceding companies and brokers that place such business move to other reinsurers with higher ratings and therefore such downgrade may materially and adversely impact our business, operating results, liquidity and financial flexibility.

In addition, a downgrade of the financial strength rating of Aspen UK, Aspen Bermuda, AAIC or Aspen Specialty by A.M. Best below "B++" would constitute an event of default under one or more of our financing facilities. Additionally, the cost and availability of unsecured financing are generally dependent on the borrower's long-term and short-term debt ratings. A lower rating may lead to higher borrowing costs, thereby adversely impacting our liquidity and financial flexibility and by extension our business, financial condition and results of operations.

**Increasing scrutiny and evolving expectations from investors, customers, regulators, policymakers and other stakeholders regarding environmental, social and governance matters may adversely affect our reputation or otherwise adversely impact our business and results of operations.**

Environmental, social and governance ("ESG") considerations encompass a wide range of issues, including climate change and other environmental and social risks, and failure to communicate a clear strategy to manage these risks and/or lacking progress on the implementation of a comprehensive climate risk management framework may pose reputational or litigation risks. Internal and external stakeholders, including regulators and investors, have placed increased and rapidly evolving importance on how we are addressing ESG issues. Reputational risks develop through the insurance coverage provided, or not provided, to policyholders that conduct business activities with negative impacts on the climate or from investments held in certain industries, or via Aspen's operations and internal programs, directly or via third parties that provide services for us. Regulators and lawmakers have adopted and may continue to adopt ESG-related laws, rules and guidance, which may conflict with one another and impose additional costs and operational burdens on us. A lack of harmonization globally and within jurisdictions in relation to ESG legal and regulatory reform leads to a risk of fragmentation in group level priorities as a result of the different pace and type of sustainability transition across global jurisdictions. This may create conflicts across our global business which could risk inhibiting our future implementation of, and compliance with, rapidly developing ESG standards and requirements, and potentially pose litigation, investigation and/or reputational risks. While we have procedures to monitor regulatory change, it is not possible to predict the impact of such regulatory or legislative changes, and such changes may affect the way we conduct our business and manage our capital and risk profile, which in turn could affect our results of operations, financial condition and liquidity. If we are unable to meet targets, standards, or expectations, whether established by us or third parties, it could result in adverse publicity, reputational harm, or loss of customer and/or investor confidence, which could adversely affect our business and results of operations. For further information, see "—*Risks Related to Our Business—Global climate change may have an adverse effect on our results of operations, financial condition or liquidity*."

**Any future acquisitions, growth of our operations through the addition of new lines of (re)insurance business, expansion into new geographic regions and/or joint ventures or partnerships may expose us to risks.**

There can be no assurance that the integration of acquired businesses or new personnel will be successful, that we will realize anticipated synergies, cost savings and operational efficiencies, or that the business acquired will prove to be profitable or sustainable. The failure to integrate acquired businesses successfully or to manage the challenges presented by the integration process may adversely impact our financial results. Acquisitions could involve numerous additional risks such as potential losses from unanticipated litigation or levels of claims and inability to generate sufficient revenue to offset acquisition costs. In addition, the value of assets acquired may be lower than expected or may diminish due to credit defaults or changes in interest rates or the liabilities assumed may be greater than expected. Our ability to grow through acquisitions will depend, in part, on our success in addressing these risks. Our failure to manage successfully any of the foregoing challenges and risks may adversely impact our results of operations.

For further details, refer to "R*isks Related to the Merger - "The completion of the Merger may not result in the anticipated benefits and could adversely affect our business, financial condition, and results of operations*."

**We depend on a few brokers for a large portion of our insurance and reinsurance revenues and the loss of business provided by any one of those brokers could adversely affect us.**

In our insurance business, ten brokers collectively accounted for 64.3% of our gross written premiums for the twelve months ended December 31, 2025. The top three brokers out of these ten were Arthur J. Gallagher, Aon Corporation and Marsh & McLennan Companies, Inc. accounting for 13.0%, 10.1% and 10.0% of such gross written premiums, respectively, for the twelve months ended December 31, 2025. Refer to "*Business Overview—Business Distribution*" below for our principal brokers by segment. Our relationships with our brokers and agents are based on the quality of our underwriting and claim services, as well as our financial strength ratings. Any deterioration in these factors could result in the brokers advising our clients to place their business with other (re)insurers. In addition, these brokers and agents also have, or may in the future acquire, ownership interests in insurance and reinsurance companies that may compete with us and these brokers may favor their own (re)insurers over other companies. Loss of all or a substantial portion of the business provided by one or more of these brokers could have a material adverse impact on our business and results of operations.

We market our reinsurance worldwide primarily through reinsurance brokers and derive a significant portion of our business from a limited number of brokers. For the twelve months ended December 31, 2025, three brokers, Marsh & McLennan Companies, Inc., Aon Corporation and Arthur J Gallagher, accounted for 31.0%, 22.3% and 14.2%, respectively, of our reinsurance gross written premiums.

In addition, there has been a trend of increased consolidation of agents and brokers and of agents and brokers strategically reducing the numbers of insurers with which they do business to gain efficiency for their placement efforts. As we distribute most of our products through agents and brokers, consolidation could impact our ability to access business and our relationships with, and fees paid to, agents and brokers. In the Lloyd's market, independent London wholesalers continue to be acquired by larger global brokers, which may result in enhanced market power for these larger brokers in placing (re)insurance. In the U.S. market, larger regional retailers are also being acquired by the larger global brokers. Consolidation of distributors may also increase the likelihood that distributors will try to renegotiate the terms of existing broker service arrangements or policy terms, pricing and conditions to terms less favorable to us. As brokers merge with or acquire each other, any resulting failure or inability of brokers to market our products successfully, or the loss of a substantial portion of the business sourced by one or more of our key brokers, could have a material adverse effect on our business and results of operations.

As a result, the loss of a broker, through a merger, acquisition or otherwise, could result in a loss of a business, which would reduce our premium volume and could have a material adverse effect on us. Further, due to the concentration of our brokers, they may have an increased power to dictate their terms and conditions of our arrangements with them, which could have a negative impact on our business.

**We are exposed to risks in connection with our management of alternative reinsurance platforms on behalf of investors in any entities ACM manages or could manage in the future.**

Those of our subsidiaries that are engaged in the management of alternative reinsurance platforms as part of our ACM division may owe certain legal duties and obligations to third-party investors (including reporting obligations) and are subject to a variety of often complex laws and regulations relating to the management of those structures. Although we continually monitor our policies and procedures to ensure compliance, faulty judgments, simple errors or mistakes, or the failure of our personnel to adhere to established policies and procedures could result in our failure to comply with applicable laws or regulations which could result in significant liabilities, penalties or other losses and significantly harm our business and results of operations. Additionally, ACM also raises capital from third-party investors that may be invested in a vehicle that is a reinsurer of an Aspen entity but may be managed by a third-party administrator.

Our third-party investors may decide to redeem their interests, which could materially impact the financial condition of the entities supporting our underwriting. Certain of our third-party capital investors provide significant capital investment. The loss or alteration of this capital support, such as in response to substantial or sustained losses ceded over a number of years, could be detrimental to our financial condition and results of operations. Moreover, we can provide no assurance that we may be able to attract and raise additional third-party capital for our existing entities or for potential new entities and therefore we may forego existing and/or potential attractive fee income and other income-generating opportunities.

Furthermore, notwithstanding any capital holdback, we may decide to return to our investors all or a portion of their capital held as collateral prior to the maturity specified in the terms of the particular underlying transactional documents. A return of capital to our investors is final. As a result, if we release collateral early and capital is returned to our investors, we may not have sufficient collateral to pay the claims associated with such losses in the event losses are significantly larger than we anticipated. In addition, the value of any collateral held may be impacted by macroeconomic, geopolitical or other factors that could lead to investment volatility.

**We may require additional capital in the future, which may not be available or may only be available on unfavorable terms, and we may have to raise capital following significant insured losses.**

Our future capital requirements depend on many factors, including our ability to write new business successfully, deploy capital into more profitable business lines, identify acquisition opportunities, manage investments and preserve capital in volatile markets, and establish premium rates and reserves at levels sufficient to cover losses.

We require liquidity to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pay claims;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fund our operating expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• to the extent declared, pay dividends (including the payment of dividends to the holders of our Preference Shares);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fund liquidity needs caused by investment losses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• replace or improve capital in the event of a depletion of our capital as a result of significant reinsurance losses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• meet rating agency or regulatory capital requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• respond to competitive pressures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• service our debt; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• meet capital requirements.

To the extent our funds are insufficient or unavailable to fund future operating requirements or cover claims losses, whether due to regulatory or contractual restrictions (such as to pay additional or callable contributions to the Lloyd's central fund), underwriting or investment losses or otherwise, we may need to raise additional funds through corporate finance transactions or curtail our growth and reduce our liabilities. Any such financing, if available at all, may be on terms that are not favorable to us. Additionally, in a rising interest rate environment, such financing may result in a higher cost of capital. Our ability to raise such capital successfully would depend upon the facts and circumstances at the time, including our financial position and operating results, market conditions and applicable regulatory filings and legal issues. If we cannot obtain adequate capital on favorable terms, or obtain it at all, our business, financial condition and operating results could be adversely affected. Furthermore, financial markets have experienced extreme volatility and disruption due in part to financial stresses affecting the liquidity of the banking system and the financial markets generally. These circumstances have reduced access to the public and private equity and debt markets at such times.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

In addition, we may not achieve the desired regulatory capital treatment for any potential issuance of debt or equity securities due to changing solvency capital eligibility requirements under the Bermuda Insurance (Group Supervision) Rules 2011, as amended from time to time (the "Group Supervision Rules") to which we are subject. For these instruments to continue to receive the intended regulatory capital treatment, their terms must reflect the criteria contained in the Group Supervision Rules and any amendments thereto. If the BMA applies any changes to the Group Supervision Rules governing eligible capital such that our outstanding Preference Shares or other securities we may issue in the future no longer receive their intended capital treatment under the Group Supervision Rules, we may be unable to maintain adequate regulatory capital. If we cannot obtain adequate capital or credit, our business, results of operations and financial condition could be adversely affected by, among other things, our inability to finance future acquisitions.

**Our debt, credit and International Swaps and Derivatives Association ("ISDA") agreements may limit our financial and operational flexibility, which may affect our financial condition, liquidity and ability to conduct our business.**

We have incurred indebtedness and may incur additional indebtedness in the future, including the 2030 Senior Notes (for more information about the 2030 Senior Notes, refer to Item 5B — "*Liquidity and Capital Resources"*). Additionally, we have entered into credit facilities with various institutions which provide revolving lines of credit to us and our Operating Subsidiaries and issue letters of credit to our clients in the ordinary course of business. We have also entered into ISDA agreements relating to derivative transactions.

The agreements relating to our debt, including the 2030 Senior Notes, credit or financing facilities and our ISDA agreements may contain covenants that may limit our ability, among other things, to borrow money, make particular types of investments or other restricted payments, sell assets, merge or consolidate. Such agreements also typically contain reporting and disclosure affirmative covenants. Some of these agreements also require us to maintain specified ratings and financial ratios, including a minimum net worth covenant. If we fail to comply with these covenants or meet required financial ratios, the lenders or counterparties under these agreements could declare a default and demand immediate repayment of all amounts owed to them and require collateralization of any current or future obligations of the Company. Additionally, a default under our debt, credit facilities or ISDA agreements could limit our ability to obtain credit or enter into such transactions on favorable terms, or at all. As a result, our business, financial condition and operating results could be adversely affected.

If we are in default under the terms of these agreements, we may also be restricted in our ability to declare or pay any dividends, redeem, purchase or acquire any shares or make a liquidation payment and are at risk of cross-default on other arrangements. In addition, the cost and availability of these arrangements vary and any adverse change in the cost or availability of such arrangements could adversely impact our business, financial condition and operating results.

***Regulatory Risks***

**Political, regulatory, governmental and industry initiatives, as well as the increasing variety and scope of laws, regulation and litigation in the area of climate change and AI, as well as changes in regulations that may adversely impact the U.S. mortgage insurance and reinsurance market, may have a material adverse effect on our business, financial condition, results of operations, liquidity, cash flows and prospects.**

Certain of the laws and regulations to which our Operating Subsidiaries are subject are summarized under "Certain Regulatory Considerations." Changes in the laws and regulations relevant to our business may have a material adverse effect on our business, financial condition, results of operations, liquidity, cash flows and prospects. The laws and regulations of the jurisdictions in which our insurance and reinsurance subsidiaries are domiciled require, among other things, maintenance of minimum levels of statutory capital, surplus, and liquidity; various solvency standards; and periodic examinations of subsidiaries' financial condition. In some jurisdictions, laws and regulations also restrict payments of dividends and reductions of capital and require prior approval in connection with a potential acquisition or change of control. Applicable statutes, regulations, and policies may also restrict the ability of these subsidiaries to write insurance and reinsurance policies, to make certain investments, and to distribute funds. In addition, as industry practices and legislative, regulatory, judicial, social, financial, technological and other environmental conditions change, unexpected and unintended issues related to claims and coverage may emerge. These issues may adversely affect our business by either extending coverage beyond our underwriting intent or by increasing the frequency and severity of claims. In some instances, these changes may not become apparent until after we have issued insurance or reinsurance contracts that are affected by the changes.

Some of these authorities regularly consider enhanced or new regulatory requirements intended to prevent future crises or otherwise assure the stability of institutions under their supervision. These authorities may also seek to exercise their supervisory authority in new and more robust ways, and new regulators could become authorized to oversee parts of our business. The purpose of insurance laws and regulations generally is to protect policyholders and ceding insurance companies, not our shareholders or other security holders. Failure to comply with or obtain appropriate authorizations and/or exemptions under any applicable laws and regulations could result in restrictions on our ability to do business or undertake activities that are regulated in one or more of the jurisdictions in which we conduct business and could subject us to fines, other sanctions and reputational injury.

It is not possible to predict all future impacts of political, regulatory, governmental or industry changes but they could affect the way we conduct our business and manage our capital, and may require us to satisfy increased capital requirements or to incur additional expenses, any of which, in turn, could affect our results of operations, financial condition and liquidity. Additionally, changes in regulations may result in discrepancies or conflicts among the jurisdictions in which we operate, which may increase our compliance burdens and costs, and new or changing laws, tariffs on services or goods or other protectionist measures may adversely impact our operational and compliance costs. With respect to tariffs, it is unclear how recently-announced tariffs and tariff disputes may impact our business, but there may be a ripple effect on how these impact certain industries which we support through the provision of our insurance and reinsurance products. Sustained escalation of tariff setting and tariff disputes has the potential to result in a global economic slowdown. In addition, it is anticipated that the US executive branch will continue to promulgate executive orders or propose legislation or agency rulemaking initiatives that could impact our industry. We cannot predict with certainty the impact of these actions on our business and results of operations.

The foreign and U.S. federal and state laws and regulations that are applicable to our operations, including those at Lloyd's are complex and may increase the costs of regulatory compliance or subject our business to the possibility of regulatory actions or proceedings. In addition to insurance and financial industry regulations, our activities are also subject to relevant economic and trade sanctions administered by the U.S. Department of the Treasury's Office of Foreign Assets Control, the U.S. Department of State, the U.S. Department of Commerce, the United Nations Security Council and other relevant sanctions authorities, as well as money laundering regulations, which may increase the costs of regulatory compliance, limit or restrict our ability to do business or engage in certain regulated activities, or subject us to the possibility of regulatory actions, proceedings and fines.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Our global operations expose us to the risk of violating, or being accused of violating, economic and trade sanctions laws and regulations. As part of our business, we may, from time to time, engage in limited sales and transactions involving certain countries, entities and individuals that are targets of economic sanctions, provided that such sales and transactions are authorized pursuant to applicable economic sanctions laws and regulations. However, we cannot predict the nature, scope or effect of future regulatory requirements, including changes that may affect existing regulatory authorizations, and we cannot predict the manner in which existing laws and regulations might be administered or interpreted. Further, while we maintain policies and procedures designed to maintain compliance with applicable economic and trade sanctions, there can be no guarantee that our policies and procedures will be effective in preventing violations, which could adversely affect our reputation, business, financial condition or results of operations. If in the future we are found to be in violation of U.S. or other applicable economic sanctions or export control laws, it could result in substantial fines and penalties for us, including criminal fines, imprisonment, civil fines, disgorgement of profits, injunctions and other remedial measures. Investigations of alleged violations can be expensive and disruptive. The insurance industry is also affected by political, judicial, and legal developments that may create new and expanded regulations and theories of liability. The current economic and financial climates present additional uncertainties and risks relating to increased regulation and the potential for increased involvement of the United States and other governments in the financial services industry.

In response to changes to U.S. credit for reinsurance rules arising from the 2017 Covered Agreement between the United States and European Union ("E.U.") and the 2018 Covered Agreement between the United States and the United Kingdom, Aspen Bermuda has obtained reciprocal jurisdiction reinsurer status with Texas as its lead state. Reinsurers licensed in reciprocal jurisdictions (which include the United Kingdom, E.U. member states, Bermuda, Japan and Switzerland) are not required to post reinsurance collateral to U.S. cedants if approved as reciprocal jurisdiction reinsurers in the cedant's U.S. state of domicile. With its approval from Texas, Aspen Bermuda was able to facilitate passporting applications in additional U.S. states throughout 2022, with renewal of the same for all U.S. states, plus Washington D.C. and Puerto Rico, now operationalized and embedded. "Passporting" refers to the process under which a U.S. state has the discretion to defer to the determination by another U.S. state that a reinsurer is a reciprocal jurisdiction reinsurer, thereby excusing the approved reinsurer from collateral requirements in such state. Aspen Bermuda also retains its status as a certified reinsurer in a number of U.S. states, enabling it to provide reduced collateral for historical risks written. There is no guarantee that Aspen Bermuda will maintain its reciprocal jurisdiction reinsurer or certified reinsurer status, and changes in laws and regulations applicable to the provision of collateral by offshore or unauthorized reinsurers such as Aspen Bermuda may have a material adverse impact on our capital management approach, financial condition, results of operations, liquidity, cash flows and prospects. Refer to "*Certain Regulatory Considerations—U.S. Regulation—Credit for Reinsurance*" for more information.

In the event or absence of changes in applicable laws and regulations in particular jurisdictions, we may from time to time face challenges, or changes in approach to oversight of our business from insurance or other regulators, including challenges resulting from implementing new or additional processes or procedures that cannot be quickly adapted to address new regulatory requirements. Moreover, we could be, or our employees acting on our behalf, could be found to have violated existing laws, rules or regulations. Our regulators, as well as Lloyd's, have the ability to make regulatory interventions using their powers, including through investigations, requests for data and analysis, interviews or reviews, additions to "watchlists" (including, but not limited to, skilled persons reports under section 166 of the U.K. Financial Services and Markets Act 2000 ("FSMA")), which regulatory intervention may require, or may in the past have imposed, specific remediation, including via guidance on a confidential basis, in respect of historical practices, changes to our existing practices, public censure, financial or other penalties, the loss or restriction of regulatory permissions necessary to carry out our business in the same manner as before, and/or additional regulatory capital to be held. Such matters could have a material adverse effect on our business, results of operations and financial condition.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

We are involved in periodic meetings and exams with, and reviews by, regulators, including in relation to business previously underwritten or contractual arrangements previously in place by the Company or its subsidiaries, pursuant to which they review our business and provide challenges in order to test and validate the supervisory and work plan adopted by their supervisory teams. Through such processes, our regulators may validate and/or challenge, among other things, our strategy, business plans, internal governance, risk and capital management and compliance frameworks. Our regulators have required us, and we are under continuing obligations, to remediate failures, weaknesses and other issues that they have identified, including, but not limited to, with respect to our underwriting performance, reserving risk and capital management, and governance, which, if we are unsuccessful in remediating could result in greater regulatory intrusion, enforcement action and/or the exercise of our regulators' own initiative powers (including imposing restrictions on our underwriting and/or a requirement to maintain additional capital, which would reduce our underwriting capacity). We continuously introduce and implement initiatives to improve our business, including our underwriting performance, risk and capital management and governance, which, if we are unable to successfully embed within our operations, could result in greater regulatory intrusion and/or enforcement action or the exercise of our regulators' own initiative powers, which could have a material adverse effect on our business, results of operations and financial condition. By way of illustration, in 2022, the Missouri Insurance Department requested information in connection with a short-term medical products program previously underwritten by AAIC and administered by a third-party. Initial findings have been issued and we continue to engage with the regulator. To the extent such enquiries or similar regulatory engagement results in specific required remediation or in public censure, financial or other penalties, the loss or restriction of regulatory permissions necessary to carry out our business in the same manner as before, and/or additional regulatory capital to be held, then such matters could have a material adverse effect on our business, results of operations and financial condition.

We believe it is likely there will continue to be increased regulation of, and other forms of government participation in, our industry in the future, which could materially adversely affect our business by, among other things: providing reinsurance capacity in markets and to policyholders that we target or requiring our participation in industry pools and guaranty associations; further restricting our operational or capital flexibility; expanding the scope of coverage under existing policies; regulating the terms of our (re)insurance policies; adopting further or changing compliance requirements which may result in additional costs which may adversely impact our results of operation; or disproportionately benefiting the companies domiciled in one country over those domiciled in another.

We maintain policies and procedures designed to comply with applicable anti-corruption laws and regulations. However, we cannot provide assurance that our internal controls and compliance systems will always protect us from liability for acts committed by employees, agents, third parties or business partners of ours (or of businesses we acquire or partner with) that would violate U.S. and/or non-U.S. laws, including the laws governing payments to government officials, bribery, fraud, kickbacks and other related laws. Any such improper actions or allegations of such acts could subject us to significant sanctions, including civil or criminal fines and penalties, disgorgement of profits, injunctions and debarment from government contracts, as well as related shareholder lawsuits and other remedial measures, all of which could adversely affect our reputation, business, financial condition and results of operations. Investigations of alleged violations can also be disruptive and cause us to incur significant legal and investigatory fees.

We are subject to complex and changing laws, regulations and increasingly divided / or polarizing public policy debates relating to climate change, including differences, and increasingly, potential conflicts in policy perspective across the jurisdictions within which we operate, which are difficult to predict and quantify, and may have an adverse impact on our business. Changes in regulations relating to climate change (including the slowing, stopping, changing or reversal of such regulations), or our own leadership decisions implemented as a result of assessing the impact of climate change (or associated regulatory obligations) on our business may result in an increase in the cost of doing business or a decrease in premiums. For further information, see "—*Strategic Risks—Increasing scrutiny and evolving expectations from investors, customers, regulators, policymakers and other stakeholders regarding environmental, social and governance matters may adversely affect our reputation or otherwise adversely impact our business and results of operations*."

With new technologies and AI tools emerging at a rapid pace, there is no assurance that we will be able to evaluate and integrate new technologies or update our existing systems to keep pace with our competitors and customer needs. While we believe AI presents significant opportunities to support our strategic goals, we may not be successful in implementing AI technologies. It is possible that any AI we use does not perform as anticipated, suffers from "hallucinations" or that its outputs may not be as expected or may result in unlawful discrimination, which may put us at a competitive disadvantage, result in reputational damage and regulatory fines and actions. The shifting regulatory landscape surrounding traditional AI and generative AI is evolving, and the expanded use of these technologies may become subject to regulatory scrutiny under new or existing laws. Moreover, the intellectual property and ownership rights associated with both forms of artificial intelligence have not been fully addressed by courts in the U.S. or in other jurisdictions that we operate in. Failure to comply with the applicable AI related regulations could result in fines, penalties, litigation, or restrictions on our business operations. These outcomes may have a materially adverse effect on our business or financial condition.

In addition to the general regulatory risks to which we are subject, the reinsurance we write could also be indirectly affected by various additional regulations relating particularly to our U.S. mortgage reinsurance operations. U.S. federal and state regulations affect the scope of operations of mortgage guaranty insurers, commercial credit insurers and the government-sponsored enterprises ("GSEs") to whom we provide credit reinsurance. Legislative and regulatory changes could cause demand for private mortgage insurance to decrease, which could have an adverse impact on our U.S. mortgage reinsurance operations. Increases in the maximum loan amount that the U.S. Federal Housing Administration can insure, and reductions in the mortgage insurance premiums it charges, can reduce the demand for private mortgage insurance. Decreases in the maximum loan amounts GSEs, such as the Federal National Mortgage Association (Fannie Mae) and the Federal Home Loan Mortgage Corporation (Freddie Mac), will purchase or guarantee, increases in GSE fees, or decreases in the maximum loan-to-value ratio for loans the GSEs will purchase, can also reduce demand for private mortgage insurance. Changes to the GSEs' capital requirements via the Enterprise Regulatory Capital Framework could decrease their use of credit-risk transfer transactions, a key element of our mortgage reinsurance business. Changes in these laws or regulations could have an indirect adverse impact on the profitability of our U.S. mortgage reinsurance business.

**The United Kingdom**'**s withdrawal from the European Union has had, and may continue to have, an adverse impact on our business, results of operations and financial condition.**

The Company continues to face regulatory costs and challenges as a result of Brexit. Mutual equivalence between the United Kingdom and European Union in relation to financial services has not been recognized as of December 31, 2025.

As a result of Brexit, Aspen UK has lost its financial services passports which provided it the license to operate across borders within the European Economic Area (the "EEA") without obtaining local regulatory approval where insurers and cedants are located. The Company's Lloyd's operations are able to continue in the EEA through Lloyd's Insurance Company, S.A. ("Lloyd's Insurance Company").

However, operational and capital requirements relating thereto might result in increased costs or Funds at Lloyd's and might not provide the same access to markets that the Company formerly enjoyed to conduct business in the EEA; additional collateral requirements are in place for underwriting through Lloyd's Insurance Company from the 2026 underwriting year. In addition, the ability to access the EEA market through Syndicate 4711 depends on Lloyd's being able to comply with E.U. regulations through its Belgium subsidiary. There remains a possibility that the Belgium Financial Services Markets Authority (the "Belgium FSMA") and the National Bank of Belgium ("NBB") may in future determine that the Lloyd's Insurance Company operating model and the activities performed for it by managing agents (through an outsourcing agreement between AMAL and Lloyd's) and could be construed as constituting insurance distribution under Directive (EU) 2016/97 (the "Insurance Distribution Directive"), which would therefore require managing agents to be authorized within the EEA.

**We face risks related to changes in Bermuda law and regulations, and the political environment in Bermuda.**

We are incorporated and headquartered in Bermuda and one of our principal Operating Subsidiaries, Aspen Bermuda, is domiciled in Bermuda, as well as our ACM entities. Therefore, changes in Bermuda law and regulation may have an adverse impact on our operations, such as the imposition of corporate income tax liability and increased regulatory supervision.

In addition, we are subject to changes in the political environment in Bermuda, which could make it difficult to operate in, or attract talent to, Bermuda. In addition, Bermuda, which is currently an overseas territory of the United Kingdom, may consider changes to its relationship with the United Kingdom in the future. These changes could adversely affect Bermuda or the international reinsurance market focused there, either of which could adversely impact us commercially.

**As a result of the merger, we are or may become subject to Japanese regulations as a result of our acquisition by Sompo, which may increase our compliance costs and burden and may subject us to additional liability.**

Following the Merger, as a wholly-owned indirect subsidiary of a Japanese insurance company, we are or may become subject to additional laws, rules and regulations, as a result of our parent company that may differ materially from those in the jurisdictions in which we currently operate. These requirements may include, among other things, licensing and registration obligations, capital adequacy and governance requirements, and additional supervisory compliance obligations. For further details, refer to Item 4A – *Business – Certain Regulatory Considerations – Group Supervision*.

Compliance with these requirements may be complex, time-consuming and costly, particularly where such frameworks differ from the requirements in other jurisdictions in which we operate. In addition, Japanese regulatory authorities may have broad discretion in interpreting and enforcing applicable Japanese laws and regulations, and may impose conditions on our operations, delay or deny approvals, or require changes to our business practices.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Our failure, or any perceived failure, to comply with applicable Japanese laws, rules and regulations, could result in regulatory actions, restrictions on our business activities, or reputational harm. Moreover, changes in laws or regulations, or in their interpretation or enforcement, could require us to modify our business model or operations in ways that are costly or that adversely affect our revenues or profitability.

**Changes in current accounting practices and future pronouncements may materially impact our reported financial results.** 

Unanticipated developments in accounting practices may require us to incur considerable additional expenses to comply with such developments, particularly if we are required to prepare information relating to prior periods for comparative purposes or to apply the new requirements retroactively. Such developments may also significantly impact the presentation of such financial statements and may require restatements. The impact of changes in current accounting practices and future pronouncements cannot be predicted but they may affect the calculation of net income, net equity and other relevant financial statement line items.

***Other Operational Risks***

**Our internal controls over financial reporting have gaps or other deficiencies.** 

Operational risk and losses can result from, among other things, fraud, errors, failure to document transactions properly or to obtain proper internal authorization, failure to comply with regulatory requirements, information technology failures and failure to appropriately transition new hires or external events. We continue to enhance our operating procedures and internal controls (including information technology initiatives and controls over financial reporting) to effectively support our business and our regulatory and reporting requirements. Our management does not expect that our disclosure controls or our internal controls will prevent all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. As a result of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty, and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons or by collusion of two or more people. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with the policies or procedures may deteriorate. As a result of the inherent limitations in a cost-effective control system, misstatement due to error or fraud may occur and not be detected.

We are required, pursuant to the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"), to furnish a report from management on, among other things, the effectiveness of our internal control over financial reporting in connection with the filing of our annual report on Form 20-F that is filed with the SEC. In addition, following our initial public offering of our Class A ordinary shares in May 2025 (the "IPO"), we became subject to the requirement under the Sarbanes-Oxley Act to obtain from our auditors an attestation report on the effectiveness of our internal control over financial reporting, and to disclose such report in our annual report on Form 20-F for the year ended December 31, 2025.

We are currently required to report, among other things, control deficiencies that constitute a "material weakness" or changes in internal controls that, or that are reasonably likely to, materially affect internal controls over financial reporting. A "material weakness" is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of our annual or interim consolidated financial statements will not be prevented or detected on a timely basis. We have identified material weaknesses in our internal controls in the past, including as of December 31, 2025, and we may identify additional future material weaknesses.

In the course of assessing the effectiveness of the Company's internal control over financial reporting as of December 31, 2025, management identified a material weakness in the design and operating effectiveness of existing internal controls within its process level controls over its Claims function. The material weakness was a result of deficiencies in the design and operation of transaction-level internal controls over the input of financial and non-financial claims data. While the Company is implementing changes designed to improve its internal controls over financial reporting and to remediate the material weakness, as further described in Item 15 - "*Controls and Procedures*", there is no guarantee that such changes will be successful or that the Company will not identify new material weaknesses in the future.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

If we identify any additional material weaknesses in our internal control over financial reporting, fail to properly remediate the existing material weaknesses identified, or are unable to comply with the requirements of Section 404 of the Sarbanes-Oxley Act or assert that our internal control over financial reporting is effective in the future, if we are required to make restatements of our financial statements, or if our independent registered public accounting firm is unable to express an opinion as to the effectiveness of our internal control over financial reporting, investors may lose confidence in the accuracy, completeness or reliability of our financial reports and the trading price of our shares may be adversely affected, and we could become subject to sanctions or investigations by the NYSE, the SEC or other regulatory authorities, which could require additional financial and management resources. In addition, if we fail to remedy any material weakness, our financial statements could be inaccurate and we could face restricted access to the capital markets.

**Management turnover or our inability to attract and retain senior staff, including our executive officers, senior underwriters or other members of our senior management team, particularly as a result of the Merger, creates uncertainties and could harm our business.**

We rely heavily on our executive officers to manage our operations for the success of our business. Management must have a thorough understanding of our various business lines, as well as the skills and experience necessary to manage our organization. Often, the appointment of new executives leads to changes in strategic or operating goals, which can create uncertainty and negatively impact our ability to execute quickly and effectively, and may ultimately be unsuccessful. In addition, executive leadership transition periods are often difficult as the new executives gain detailed knowledge of our operations, and friction can result from changes in strategy and management style. Management turnover inherently causes some loss of institutional knowledge, which can negatively affect strategy and execution. If we do not integrate new executives successfully, we may be unable to manage and grow our business, and our financial condition and profitability may suffer as a result. In addition, to the extent we experience additional management turnover, competition for top management is high and it may take time to find a candidate that meets our requirements. If we are unable to attract and retain qualified management personnel, our business could suffer. We are unable to predict with certainty the impact that any leadership changes may have on our business operations, prospects, financial results, retention of key professionals and other employees or morale.

Additionally, our success has depended and will continue to depend, in substantial part, on our ability to attract and retain our teams of underwriters in various business lines and other key employees. The loss of one or more of our senior underwriters could adversely impact our business by, for example, making it more difficult to retain clients or other business contacts whose relationship depends in part on the service of the departing personnel. In general, the loss of key services of any members of our current underwriting teams may adversely affect our business and operating results.

We also rely substantially upon the services of our senior management team. Although we have employment agreements with all members of our senior management team, if we were to unexpectedly lose the services of one or more of our senior management team or other key personnel, our business or ratings could be adversely affected. For example, an unplanned change in our senior management team could cause a risk of disruption to our business including, but not limited to, our underwriting, claims handling, reserving and financial reporting functions. We do not currently maintain key-man life insurance policies with respect to any of our employees.

This risk may be heightened following the Merger, as changes in our ownership and leadership, reporting structures or compensation arrangements could increase uncertainty among senior leadership and other key personnel and adversely affect retention. For further details, refer to "*Risks Related to the Merger - "The completion of the Merger may not result in the anticipated benefits and could adversely affect our business, financial condition, and results of operations*."

**Our business may be adversely affected if third-party outsourced service providers fail to satisfactorily perform certain technology and business process functions.**

We outsource certain technology and business process functions to third parties including offshore and cloud service providers and may increasingly do so in the future. If we do not effectively develop, implement and monitor our outsourcing strategy, third-party providers do not perform as anticipated or we experience technological or other problems with a transition, we may not realize productivity improvements or cost efficiencies and may experience operational difficulties, increased costs and loss of business. Our outsourcing of certain technology and business processes and functions to third parties may expose us to enhanced risks related to data security, which could result in monetary and reputational damages. In addition, our ability to receive services from third-party providers may be impacted by cultural differences, political instability, unanticipated regulatory requirements or policies. Lloyd's outsources certain market-wide technology and business process functions, on which participants in the Lloyd's market, such as Aspen Lloyd's, depend. Efforts to replace such systems have been delayed. As a result, our ability to conduct our business may be adversely affected.

**We may be exposed to general employee and third-party litigation risks, which could harm our business, financial condition, and results of operations.**

In the ordinary course of business, we may be involved in various litigation matters, including but not limited to commercial disputes, employee claims, shareholder claims and class actions (including, by way of example, employee allegations of improper termination and discrimination and claims related to violations of applicable government laws regarding religious freedom, advertising and intellectual property) and from time to time may be involved in governmental or regulatory investigations, exams or inquiries or similar matters arising out of our current or future business (including, but not limited to, in connection with the Merger). Any claims asserted against us, regardless of merit or eventual outcome, could harm our reputation and have an adverse impact on our relationship with our customers, partners and other third parties and could lead to additional related claims. Our insurance or indemnities may not cover all claims that may be asserted against us, and any claims asserted against us, regardless of merit or eventual outcome, may harm our reputation and cause us to expend resources in our defense. Furthermore, there is no guarantee that we will be successful in defending ourselves in future litigation or similar matters under various laws. If judgments or settlements in any future litigation or investigation significantly exceed our insurance coverage, our business, financial condition, and results of operations could be adversely affected.

For further details, refer to "*Risks Related to the Merger - "The completion of the Merger may not result in the anticipated benefits and could adversely affect our business, financial condition, and results of operations*."

**As a foreign private issuer and "controlled company" within the meaning of the NYSE corporate governance rules, we are permitted to, and do, rely on exemptions from certain of the NYSE corporate governance standards.** 

The corporate governance rules of the NYSE require listed companies to have, among other things, a majority of independent directors and independent director oversight of executive compensation, nomination of directors and corporate governance matters. As a foreign private issuer, we rely on the foreign private issuer exemption to certain NYSE rules and, where applicable, follow home country practice in lieu of the above requirements. As long as we rely on the foreign private issuer exemption to certain of the NYSE corporate governance standards, a majority of the directors on the Board are not required to be independent directors (and currently our independent directors do not constitute a majority of the Board) , we are not required to have a compensation committee composed entirely of independent directors and director nominations are not required to be made, or recommended to the Board, by a nominating committee that consists entirely of independent directors. Therefore, the Board's approach to governance may be different from other companies, and, as a result, oversight of management of the Company may be more limited than if we were subject to all of the NYSE corporate governance standards. We are also subject to certain reduced disclosure obligations as a result of being a foreign private issuer. As such, investors may not have access to the same information as for similar companies that are not foreign private issuers.

We also may rely on the "controlled company" exemption under the NYSE corporate governance rules. A "controlled company" under the NYSE corporate governance rules is a company of which more than 50% of the voting power for the election of directors is held by an individual, group or another company. Following the Merger, Sompo controls all of the combined voting power of our issued ordinary shares, resulting in us remaining a "controlled company" within the meaning of the NYSE corporate governance rules. As a controlled company, we are eligible to, and, have elected not to comply with certain requirements of the NYSE corporate governance standards, including (i) the requirement that a majority of the board of directors consist of independent directors, (ii) the requirement that we have a compensation committee that is composed entirely of independent directors with a written charter addressing the committee's purpose and responsibilities and (iii) the requirement that our director nominations be made, or recommended to the Board, by a nominating committee that consists entirely of independent directors and that we adopt a written charter addressing the nominations process.

Accordingly, our shareholders will not have the same protection afforded to shareholders of companies that are subject to all of the NYSE corporate governance standards, and the ability of our independent directors to influence our business policies and affairs may be reduced.

**We may lose our foreign private issuer status which would then require us to comply with the Exchange Act's domestic reporting regime and cause us to incur significant legal, accounting and other expenses.** 

For so long as we qualify as a foreign private issuer, we are not required to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to U.S. domestic issuers. We may no longer be a foreign private issuer as early as June 30, 2026 (the last business day of the second fiscal quarter of 2026), which would require us to comply with all of the periodic disclosure and current reporting requirements of the Exchange Act applicable to U.S. domestic issuers as of January 1, 2027. In order to maintain our current status as a foreign private issuer, either (a) a majority of our voting, ordinary securities must be either directly or indirectly owned of record by non-residents of the United States or (b)(i) a majority of our executive officers or directors cannot be U.S. citizens or residents, (ii) more than 50% of our assets must be located outside the United States and (iii) our business must be administered principally outside the United States. If we lose our status as a foreign private issuer, we would be required to comply with the Exchange Act reporting and other requirements applicable to U.S. domestic issuers, which are more detailed and extensive than the requirements for foreign private issuers. We may also be required to make changes in our corporate governance practices in accordance with various SEC and NYSE rules. As a result of the above, you may not have the same protections afforded to shareholders of companies that are not foreign private issuers.

Should we lose our foreign private issuer status, we will incur significant additional legal, accounting and other expenses that we would not incur as a foreign private issuer, which could have a material adverse effect on our business, nature of operations and financial results.

In 2025, the SEC issued a concept release (the "Concept Release") to solicit public comment on potential changes to the definition of "foreign private issuer." If the SEC ultimately adopts rules that make it harder for us to qualify as a foreign private issuer or increase the compliance burdens and costs for foreign private issuers, the risks described above could become more significant and could manifest sooner.

**As a foreign private issuer, there is less required publicly available information concerning us than there would be if we were a U.S. public company.**

We are a "foreign private issuer," as defined in the SEC's rules and regulations and, consequently, we are not subject to all of the disclosure requirements applicable to public companies organized within the United States. For example, we are exempt from certain rules under the Exchange Act that regulate disclosure obligations and procedural requirements related to the solicitation of proxies, consents or authorizations applicable to a security registered under the Exchange Act, including the U.S. proxy rules under Section 14 of the Exchange Act. In addition, our senior management and directors are exempt from certain "short-swing" profit recovery provisions of Section 16 of the Exchange Act and related rules with respect to their purchases and sales of our securities. Following recent enacted legislation in the United States, our executive officers and directors are subject to certain reporting requirements relating to changes in the beneficial ownership of their Company equity securities under Section 16(a) of the Exchange Act. Moreover, we are not required to file periodic reports and financial statements with the SEC as frequently or as promptly as U.S. public companies.

**We rely on the execution of internal processes to maintain our operations and the operational risks that are inherent to our business, including those resulting from fraud or employee errors or omissions, may result in financial losses.** 

We rely on the effective execution of internal processes to maintain our operations. We seek to monitor and control our exposure to risks arising from these processes through a risk control framework encompassing a variety of reporting systems, internal controls, management review processes and other mechanisms. We cannot provide absolute assurance that these processes and procedures will effectively control all known risks or effectively identify unforeseen risks, or that our employees and third-party agents will effectively implement them. Loss may result from, among other things, fraud, errors, failure to document transactions properly, failure to obtain proper internal authorization, failure to comply with underwriting or other internal guidelines or failure to comply with regulatory requirements. Loss from these risks could adversely affect our business, results of operations and financial condition. In addition, insurance policies that we have in place with third parties may not protect us in the event that we experience a significant loss from these risks.

**A failure in our data security and/or technology systems or infrastructure or those of third parties, could disrupt our business, damage our reputation and cause losses.** 

Our operations rely on the secure processing, storage, and transmission of confidential and other information and assets, including in our computer systems and networks. Our business, including our ability to adequately price products and services, quantify our risks, establish reserves, provide an effective and secure service to our customers, value our investments and report our financial results in a timely and accurate manner, depends significantly on the integrity, availability and timeliness of the data we maintain, as well as the data and assets held through third-party outsourcers, service providers and systems. Cybersecurity and technology threats can include phishing scams, account takeovers, introductions of malware (including ransomware), attempts at electronic break-ins, and the computerized submission of fraudulent and/or duplicative payment requests, as well as inadvertent disclosures of sensitive information or failures of our internal systems. Any such attempted or completed breaches, interference, or failures, whether or not they involve an external or internal malicious actor, that may occur in the future could have a material adverse impact on our business, reputation, financial condition or results of operations.

In an effort to ensure the integrity of such data, we implement new security measures and systems and improve or upgrade our existing security measures and systems on a continuing basis. Although we have implemented administrative and technical controls and take protective actions to reduce the risk of cyber incidents and to protect our information technology and assets, and we endeavor to modify such procedures as circumstances warrant and negotiate agreements with third-party providers to protect our assets, such measures may be insufficient to prevent, among other things, unauthorized access, computer viruses, malware or other malicious code or cyber-attack, catastrophic events, system failures and disruptions (including in relation to new security measures and systems), employee errors or malfeasance, third-party (including outsourced service providers) errors or malfeasance, loss of assets and other security events (each, a "Security Event"). Like other global companies, we have from time to time experienced, and are likely to continue to be subject to, Security Events, none of which to date have had a material adverse impact on our business, results of operations or financial condition. If additional Security Events occur, these events may jeopardize our or our policyholders' or counterparties' confidential and other information processed and stored with us, and transmitted through our computer systems and networks potentially resulting in a violation of applicable privacy, data protection or other laws, or otherwise cause interruptions, delays, or malfunctions in our, our policyholders', counterparties' or third parties' operations, or result in data loss or loss of assets which could result in significant losses and/or fines, reputational damage or a material adverse effect on our business, financial condition or operating results. We may be required to expend significant additional resources to modify our protective measures or to investigate and remediate vulnerabilities or other exposures and to pursue recovery of lost data or assets and we may be subject to litigation and financial losses. We currently maintain cyber liability insurance that provides third-party or first party liability coverages to protect us, subject to policy limits and coverages, against certain events that could be a Security Event. However, there is no guarantee that our insurance would be sufficient to protect us, and a Security Event could nonetheless have a material adverse effect on our operating results or financial condition.

Despite the contingency plans and facilities we have in place and our efforts to observe the regulatory requirements surrounding information security, our ability to conduct business may be adversely affected by a disruption of the infrastructure that supports our business in the communities in which we are located, or of outsourced services or functions, including a disruption involving electrical, communications, transportation, or other services we use. If a disruption occurs in one location and our employees in that location are unable to conduct business or communicate with other locations, our ability to service and interact with policyholders may suffer and we may not be able to successfully implement contingency plans that depend on communication. If sustained or repeated, such business interruption, system failure, service denial or data loss and/or damage could result in a deterioration of our ability to write and process business, provide customer service, pay claims in a timely fashion or perform other necessary business functions.

**Damage to our computer infrastructure and software systems and issues relating to the incorporation of artificial intelligence solutions into our systems, or those of our competitors and suppliers, could harm our business.**

We are dependent on our information technology systems to conduct our business and drive strategic decisions, including based on data analytics. Accordingly, we may incorporate traditional and generative artificial intelligence ("AI") solutions into our information systems, governance processes (such as through the recording of meetings), products, offerings, services and features, and these solutions may become important in our operations over time. The ever-increasing use and evolution of technology, including cloud-based computing and AI, both within our own systems and within those of our suppliers, heightens the risk of cybersecurity incidents in the future and creates opportunities for the potential loss or misuse of personal data that forms part of any data set and was collected, used, stored, or transferred to run our business, and unintentional dissemination or intentional destruction of confidential information stored in our or our third-party providers' systems, portable media or storage devices may result in significantly increased business and security costs, a damaged reputation, administrative penalties, or costs related to defending legal claims. If the content, analyses, or recommendations that AI programs assist in producing are or are alleged to be deficient, inaccurate, or biased, our business, financial condition, and results of operations and our reputation may be adversely affected. AI programs may be costly and require significant expertise to develop, may be difficult to set up and manage, and require periodic upgrades. There is also a risk that we may not have access to the technology and qualified AI personnel resources to adequately incorporate ongoing advancements into our AI initiatives, including access to the licensing of key intellectual property from third parties. Our competitors or other third parties may incorporate AI into their products more quickly or more successfully than us, which could impair our ability to compete effectively and adversely affect our results of operations. Our competition may have access to greater financial and technological resources, giving them a competitive advantage in recruiting, motivating, and retaining sought-after AI professionals. AI also presents emerging ethical issues and if our use of AI becomes controversial, we may experience brand or reputational harm, competitive harm, or legal liability. The rapid evolution of AI, including potential government regulation of AI, will require significant resources to develop, test and maintain our platform, offerings, services, and features to help us implement AI ethically in order to minimize unintended, harmful impact. Our business, financial condition and operating results may be adversely affected if we do not adequately maintain our information technology systems, both internal and third party, and continuously test and upgrade them. With new technologies and AI tools emerging at a rapid pace, there is no assurance that we will be able to evaluate and integrate new technologies or update our existing systems to keep pace with our competitors and customer needs. While we believe AI presents significant opportunities to support our strategic goals, we may not be successful in implementing AI technologies. It is possible that any AI we use does not perform as anticipated, suffers from "hallucinations" or that its outputs may not be as expected or may result in unlawful discrimination, which may put us at a competitive disadvantage, result in reputational damage and regulatory fines and actions.

Such matters could have a negative impact to our business and result in business interruptions, remediation costs and/or legal claims, which could have a material adverse effect on our financial position, results of operations, cash flows and liquidity.

**Compliance with ever evolving national, federal, state, and international laws relating to the handling of information collected from or about individuals involves significant expenditure and resources, and any failure by us or our vendors to comply may result in significant liability, negative publicity and/or an erosion of trust, which could materially adversely affect our business, results of operations and financial condition.**

We receive, store, handle, transmit, use and otherwise process business information and information related to individuals, including from and about actual and prospective customers, policyholders, as well as our employees and service providers. We also depend on a number of third-party vendors in relation to the operation of our business, a number of which process data on our behalf.

We are subject to a range of data privacy and cybersecurity laws globally including those that apply generally to the handling of information about individuals, and those that are specific to certain industries, sectors, contexts or locations. These requirements, and their application, interpretation and amendment are constantly evolving and developing as set out in "*Certain Regulatory Considerations—Bermuda Insurance Regulation—Privacy & Cybersecurity Laws," "—U.K. and E.U. Insurance Regulation—E.U. / U.K. Cybersecurity and Privacy Laws and Regulations*" and "—*U.S. Regulation—Cybersecurity and Privacy Laws and Regulations.*"

Our business is also subject to the Bermuda Personal Information Protection 2016 Act ("PIPA"). For more information, refer to "*Certain Regulatory Considerations — Bermuda Insurance Regulation — Privacy & Cybersecurity Laws*." In addition to U.K./E.U. and Bermuda privacy laws, our business is subject to various U.S. state and federal privacy legislation, including both state financial privacy and insurance laws which apply specifically to our business lines, and potentially more generally applicable state privacy laws, with the most comprehensive having been enacted in California. U.S. state legislatures, attorneys general, and insurance and other regulatory bodies continue to develop and implement further standards and governance requirements. Such evolving privacy and data security regulations could expose our business to reputational harm and cause losses.

We depend on a number of third parties in relation to the operation of our business, a number of which process personal data on our behalf. There can be no assurances that the privacy and security-related measures and safeguards we have put in place in relation to these third parties will be effective to protect us and/or the relevant personal data from the risks associated with the third-party processing, storage and transmission of such data. Any violation of data or security laws, or of our relevant measures and safeguards, by our third-party processors could have a material adverse effect on our business, result in applicable fines and penalties, damage our reputation and/or result in civil claims.

We are also subject to evolving U.S., E.U. and U.K. privacy laws on cookies, tracking technologies and e-marketing. Recent court and regulator decisions are driving increased attention to cookies and tracking technologies. If the trend of increasing litigation as well as enforcement by regulators, sometimes embracing a strict approach to consent for all but essential use cases as seen in recent guidance and decisions continues, this could lead to substantial costs, require significant systems changes, limit the effectiveness of our marketing activities, divert the attention of our technology personnel, adversely affect our margins and subject us to additional liabilities. In light of the complex and evolving nature of U.S., E.U., E.U. Member State and U.K. privacy laws and litigation trends on cookies and tracking technologies, there can be no assurances that we will be successful in our efforts to comply with such laws or mitigate legal risks; violations of such laws could result in regulatory investigations, fines, orders to cease/change our use of such technologies, as well as civil claims including class actions and reputational damage.

**We use analytical models to assist our decision making in key areas such as underwriting, claims, reserving, and catastrophe risks but actual results could differ materially from the model outputs and related analyses.**

We have made substantial investments to develop proprietary analytic and modeling capabilities to facilitate our underwriting, risk management, capital modeling and allocation, and risk assessments relating to the risks we assume. We also use vendor models where available and, where appropriate, we use our proprietary model in combination with vendor models. These models and other tools help us to manage our risks, understand our capital utilization and risk aggregation, inform management and other stakeholders of capital requirements and seek to improve the risk/return profile or optimize the efficiency of the amount of capital we apply to cover the risks in the individual contracts we sell and in our portfolio as a whole. However, given the inherent uncertainty of modeling techniques and the application of such techniques, the possibility of human or systems error, the challenges inherent in consistent application of complex methodologies in a fluid business environment and other factors, our models, tools and databases may not accurately address the risks we currently cover or the emergence of new matters which might be deemed to impact certain of our coverages.

Furthermore, there are risks associated with catastrophic events, which are either poorly represented or not represented at all by analytical models. Each modeling assumption or un-modeled risk introduces uncertainty into the estimates that management must consider. These uncertainties can include, but are not limited to, the following:

–The models do not address all the possible hazard characteristics of a catastrophe peril (e.g., the precise path and wind speed of a hurricane);

–The models may not accurately reflect the true frequency of events;

–The models may not accurately reflect a risk's vulnerability or susceptibility to damage for a given event characteristic;

–The models may not accurately represent loss potential to reinsurance contract coverage limits, terms and conditions; and

–The models may not accurately reflect the impact on the economy of the area affected or the financial, judicial, political, or regulatory impact on insurance claim payments during or following a catastrophe event.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Accordingly, our models may understate the exposures we are assuming. Conversely, our models may prove too conservative and contribute to factors which may impede our ability to grow in respect of new markets or perils or in connection with our current portfolio of coverages or the loss environment otherwise may prove more benign than our capital loading for catastrophes or other modeled losses. In such case of excess capital, we would make a judgment about redeploying the capital in lines of businesses or pursuing other capital management activities, such as dividends or share repurchases, which judgment will also depend on modeling techniques and results. If capital models prove inadequate, our result of operations and financial condition may be materially adversely impacted.

**Our controlling shareholder owns all of our ordinary shares and has the power to determine the affairs of the Company, including in ways potentially not favorable to the interests of holders of the preference shares.**

As from the effective time of the Merger in February 2026, Sompo indirectly owns 100% of the ordinary shares of the Company, and Sompo controls all of the voting power for the election of the Company's directors and to determine the outcome of any action requiring shareholder approval. The interests of Sompo may differ from the interests of the holders of the preference shares and, given Sompo's controlling interest in the Company, circumstances may arise under which it may exercise its control in a manner that is not favorable to the interests of the holders of the preference shares.

From time to time in the future, we may issue additional ordinary shares, securities convertible into ordinary shares, or other equity securities (including those with rights, preferences and privileges that are senior to those of our other securities, including the preference shares) to raise additional capital or pursuant to a variety of transactions. In addition, we may from time to time seek to redeem or repurchase and/or delist the Preference Shares.

***Risks Related to the Merger***

**The completion of the Merger may not result in the anticipated benefits and could adversely affect our business, financial condition, and results of operations.** 

Although the Merger has been completed, the integration of the two companies involves significant risks and uncertainties, including potential difficulties in combining operations, systems, technologies, controls, and corporate cultures; retaining key management, employees, agents, and customers; employee and third-party litigation risks; and realizing expected synergies, cost savings, and growth opportunities within the anticipated timeframes or at all. The integration process may require substantial management attention and financial resources, potentially diverting focus from our ongoing business operations. In addition, unforeseen liabilities, integration costs, regulatory challenges, or operational disruptions may arise as a result of the Merger. If we are unable to effectively integrate with Sompo or if the expected benefits of the Merger fail to materialize, our competitive position, profitability, and long-term strategy could be materially and adversely affected.

As a result of the go-private nature of the Merger, our Company Ordinary Shares have been delisted and deregistered. Delisting and deregistration of our Company Ordinary Shares may reduce the availability of public information about us, reduce or eliminate the protections associated with certain public company reporting and governance requirements, and increase the risk of disputes or claims relating to the Merger consideration or process. These factors, individually or in the aggregate, could materially and adversely affect our business, financial condition, and results of operations. Our Preference Shares, which are discussed below, remain listed and registered on the NYSE; however, there is no guarantee that they will not be delisted and deregistered in the future. For more information regarding the Merger, refer to the "*Explanatory Note*" on page 2 of this report.

***Risks Related to Our Preference Shares***

**Our holding company structure and certain Companies Act, regulatory and other constraints may limit our ability to pay dividends on our securities.**

Aspen Holdings is a holding company and, as such, it does not have any significant operations. Aspen Holdings' assets primarily consist of ownership of the shares of its subsidiaries, including our Operating Subsidiaries, a portfolio of fixed income securities and cash and cash equivalents. Dividends and other permitted distributions and loans from our Operating Subsidiaries are expected to be our sole source of funds to meet ongoing cash requirements, including our debt service payments and other expenses, and dividend payments to our preference shareholders, as appropriate. Our Operating Subsidiaries are subject to capital, regulatory and other requirements that inform their ability to declare and pay dividends and make loans to other Aspen Group companies. See "*Certain Regulatory Considerations—Bermuda Insurance Regulation—Restrictions on Dividends, Distributions and Reduction of Capital," "Certain Regulatory Considerations—U.K. and E.U. Insurance Regulation—Restrictions on Dividend Payments by Insurers*," and "*Certain Regulatory Considerations—U.S. Regulation—State Dividend Limitations," and "Operating and Financial Review and Prospects—Liquidity and Capital Resources—Liquidity*" for more information on our ability to pay dividends. These and other requirements may mean that our Operating Subsidiaries are unable to pay sufficient dividends to enable us to meet our ongoing cash requirements, which could materially adversely affect our liquidity or financial condition. As we are a holding company, our right, and hence the right of our creditors and shareholders, to participate in any distribution of assets by any of our subsidiaries, upon our liquidation or reorganization or otherwise, is subject to the prior claims of policyholders and creditors of these subsidiaries.

Additionally, we are subject to Bermuda regulatory constraints that affect our ability to pay dividends and make other distributions on our Preference Shares or other securities. Under the Companies Act, we may declare or pay a dividend only if we have reasonable grounds to believe that we are, and would after the payment be, able to meet our liabilities as they become due and if the realizable value of our assets would thereby not be less than our liabilities. See "*Certain Regulatory Considerations—Bermuda Insurance Regulation—Restrictions on Dividends, Distributions and Reduction of Capital," "Operating and Financial Review and Prospects—Liquidity and Capital Resources—Liquidity*" and "Note 14—*Statutory Requirements and Dividends Restrictions*" to our audited consolidated financial statements for more information on our ability to pay dividends. Additionally, agreements relating to our 2030 Senior Notes, credit or financing facilities and our ISDA agreements may contain covenants that may limit our ability to pay cash dividends on our Company Ordinary Shares or Preference Shares if a default or event of default has occurred and is continuing or would result therefrom.

In addition, we may from time to time seek to redeem or repurchase and/or delist the Preference Shares.

**U.S. persons who own our securities may have more difficulty in protecting their interests than U.S. persons who are shareholders of a U.S. corporation.**

The Companies Act, which applies to us, differs in some material respects from laws generally applicable to U.S. corporations and their shareholders. These differences include, but are not limited to, the manner in which directors must disclose transactions in which they have an interest, the rights of shareholders to bring class action and derivative lawsuits, the scope of indemnification available to directors and officers and provisions relating to the amalgamations, mergers and acquisitions and takeovers. Holders of our Preference Shares may therefore have more difficulty protecting their interests than would shareholders of a corporation incorporated in a jurisdiction within the United States.

Generally, the duties of directors and officers of a Bermuda company are owed to the company only. Shareholders of Bermuda companies typically do not have rights to take action against directors or officers of the company and may only do so in limited circumstances. Class actions and derivative actions are typically not available to shareholders under Bermuda law. The Bermuda courts, however, would ordinarily be expected to permit a shareholder to commence an action in the name of a company to remedy a wrong to the company where the act complained of is alleged to be beyond the corporate power of the company or illegal, or would result in the violation of the company's memorandum of association or bye-laws. Furthermore, consideration would be given by a Bermuda court to acts that are alleged to constitute a fraud against the minority shareholders or, for instance, where an act requires the approval of a greater percentage of the company's shareholders than that which actually approved it. When the affairs of a company are being conducted in a manner that is oppressive or prejudicial to the interests of some shareholders, one or more shareholders may apply to the Supreme Court of Bermuda, which may make such order as it sees fit, including an order regulating the conduct of the company's affairs in the future or ordering the purchase of the shares of any shareholders by other shareholders or by the company. Additionally, under our bye-laws and as permitted by Bermuda law, each shareholder has waived any claim or right of action against our directors or officers for any action taken by directors or officers in the performance of their duties, except for actions involving fraud or dishonesty. In addition, the rights of holders of our securities and the fiduciary responsibilities of our directors under Bermuda law are not as clearly established as under statutes or judicial precedent in U.S. jurisdictions, particularly the State of Delaware.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

**Members of the Board are permitted to participate in decisions in which they have interests that are different from those of the other shareholders.**

Under Bermuda law, directors are not required to recuse themselves from voting on matters in which they have an interest. The directors may have interests that are different from, or in addition to, the interests of the shareholders. Provided the directors disclose their interests in a matter under consideration by the Board in accordance with Bermuda law and our bye-laws, they are entitled to participate in the deliberation on and vote in respect of that matter.

**We are a Bermuda company and it may be difficult to effect service of process on us or enforce judgments against us or our directors and executive officers in the United States.** 

We are incorporated under the laws of Bermuda and our business is based in Bermuda. In addition, as at December 31, 2025 and through to the effective date of the Merger, and following the effective time of the Merger, certain of our directors and officers reside outside the United States, and a substantial portion of our assets and the assets of such persons are located in jurisdictions outside the United States. As such, it may be difficult or impossible to effect service of process upon us or those persons in the United States or to recover against us or them on judgments of U.S. courts, including judgments predicated upon civil liability provisions of the U.S. federal securities laws.

We have been advised by Bermuda counsel that currently there is no treaty in force between the United States and Bermuda providing for the reciprocal recognition and enforcement of judgments in civil and commercial matters. As a result, whether a U.S. judgment would be enforceable in Bermuda against us or our directors and officers depends on whether the U.S. court that entered the judgment is recognized by the Bermuda court as having jurisdiction over us or our directors and officers, as determined by reference to Bermuda conflict of law rules. A judgment debt from a U.S. court that is final and for a sum certain based on U.S. federal securities laws will not be enforceable in Bermuda unless the judgment debtor had submitted to the jurisdiction of the U.S. court, and the issue of submission and jurisdiction is a matter of Bermuda (not U.S.) law.

In addition to and irrespective of jurisdictional issues, the Bermuda courts will not enforce a U.S. federal securities law that is either penal or contrary to public policy in Bermuda. It is the advice of our Bermuda counsel that an action brought pursuant to a public or penal law, the purpose of which is the enforcement of a sanction, power or right at the instance of the state in its sovereign capacity, will not be entertained by a Bermuda court. Certain remedies available under the laws of U.S. jurisdictions, including certain remedies under U.S. federal securities laws, would not be available under Bermuda law or enforceable in a Bermuda court, as they would be contrary to Bermuda public policy. Further, no claim may be brought in Bermuda against us or our directors and officers in the first instance for violation of U.S. federal securities laws because these laws have no extraterritorial jurisdiction under Bermuda law and do not have force of law in Bermuda. A Bermuda court may, however, impose civil liability on us or our directors and officers if the facts alleged in a complaint constitute or give rise to a cause of action under Bermuda law.

**Our bye-laws contain an exclusive jurisdiction provision that may discourage lawsuits against us and our directors and officers.**

Unless we consent in writing to the selection of an alternative forum, in the event that any dispute arises concerning the Companies Act or out of or in connection with our bye-laws, including any question regarding the existence and scope of any bye-law and/or whether there has been any breach of the Companies Act or our bye-laws by one of our officers or directors (whether or not such a claim is brought in the name of a shareholder or in the name of the Company), any such dispute shall be subject to the exclusive jurisdiction of the Supreme Court of Bermuda. Our bye-laws provide that this exclusive jurisdiction provision does not apply to actions predicated upon civil liability protections of U.S. federal securities laws or disputes arising under the Securities Act or the Exchange Act.

This exclusive jurisdiction provision may limit the ability of our shareholders to bring a claim in a judicial forum that such shareholders find favorable for disputes with us or our directors or officers, which may discourage such lawsuits against us and our directors and officers. Alternatively, if a court were to find this exclusive forum provision inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings described above, we may incur additional costs associated with resolving such matters in other jurisdictions, which could negatively affect our business, results of operations and financial condition.

***Risks Related to Taxation***

**Our structure involves complex provisions of tax law for which no clear precedent or authority may be available, and is subject to ongoing future potential legislative, judicial or administrative and differing interpretations.**

The tax treatment of our structure and transactions undertaken by us depends in some instances on determinations of fact and interpretations of complex provisions of tax law for which no clear precedent or authority may be available. In addition, tax rules are constantly under review, which frequently results in revised interpretations of established concepts, statutory changes, revisions to regulations and other modifications and interpretations.

Governments of jurisdictions in which we operate may enact legislation that could result in changes to tax laws and regulations, which may have a material impact on our financial position and results of operations. In particular, both the level and basis of taxation may change. We cannot predict whether any particular proposed legislation will be enacted or, if enacted, what the specific provisions or the effective date of any such legislation would be, or whether it would have any effect on us. As such, we cannot assure you that future legislative, administrative or judicial developments will not result in an increase in the amount of tax payable by us, our subsidiaries or investors, in our shares. If any such developments occur, our business, results of operations and cash flows could be adversely affected and such developments could have an adverse effect on your investment in our shares.

Our effective tax rate and tax liability is based on the application of current income tax laws, regulations and treaties. These laws, regulations and treaties are complex, and the manner in which they apply to us and our subsidiaries is sometimes open to interpretation. Significant management judgment is required in determining our provision for income taxes and our deferred tax assets and liabilities. Although management believes its application of current laws, regulations and treaties to be correct and sustainable upon examination by the tax authorities, the tax authorities could challenge our interpretation and the final determination of tax upon resolution of any such challenge could be materially different from our historical tax provisions and accruals. Should additional material taxes be assessed, there could be an adverse effect on our results of operations and cash flows in the period or periods for which that determination is made.

**Our non-U.S. companies may be subject to U.S. taxes, which may have a material adverse effect on our operating results and your investment.** 

Aspen Holdings and its non-U.S. subsidiaries (other than AUL and Aspen UK) intend to manage their business so that they are not treated as engaged in a trade or business within the United States and thus not subject to U.S. federal income tax on their net income. However, because there is considerable uncertainty as to the activities which constitute being engaged in a trade or business within the United States, we cannot be certain that the U.S. Internal Revenue Service ("IRS") will not contend successfully that one or more of these companies is engaged in a trade or business in the United States. If any of these companies is considered to be engaged in a trade or business in the United States during a taxable year, it generally will be subject to U.S. federal income tax (including an additional branch profits tax) on its net income that is treated as effectively connected with the conduct of a U.S. trade or business for such year (except to the extent an applicable income tax treaty provides otherwise), in which case its operating results could be materially adversely affected.

Non-U.S. corporations not engaged in a trade or business within the United States are nonetheless subject to United States income tax imposed by withholding on certain "fixed or determinable annual or periodical gains, profits and income" derived from sources within the United States (such as dividends and certain interest on investments), subject to exemption under the U.S. Internal Revenue Code (the "Code") or reduction by applicable treaties.

The United States also imposes an excise tax on insurance and reinsurance premiums ("FET") paid to non-U.S. insurers or reinsurers that are not eligible for the benefits of a U.S. income tax treaty that provides for an exemption from the FET with respect to risks (i) of a U.S. entity or individual, located wholly or partially within the United States and (ii) of a non-U.S. entity or individual engaged in a trade or business in the U.S., located within the United States. The rates of tax are 4% for property casualty insurance premiums and 1% for reinsurance premiums.

**Our non-U.K. companies may be subject to U.K. tax, which may have a material adverse effect on our operating results and your investment.** 

None of our non-U.K. entities should be treated as being resident in the U.K. for corporation tax purposes except for our subsidiaries that are incorporated in the United Kingdom (the "U.K. Subsidiaries"). A company which is not incorporated in the United Kingdom should not be treated as being tax resident in the United Kingdom unless its central management and control is exercised in the United Kingdom. The concept of central management and control is indicative of the highest level of control of a company, and determining where this is exercised is wholly a question of fact. Our non-U.K. entities currently intend to manage their affairs so that none of them, other than the U.K. Subsidiaries, are resident in the United Kingdom for tax purposes, including through compliance with established tax operating guidelines, where applicable.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

A company that is not resident in the United Kingdom for corporation tax purposes can nevertheless be subject to U.K. corporation tax if it carries on a trade in the United Kingdom through a permanent establishment in the United Kingdom but, in that case, the charge to U.K. corporation tax is limited to profits (both revenue profits and capital gains) attributable directly or indirectly to such permanent establishment.

None of our non-U.K. entities currently intend to operate in such a manner that any (other than the U.K. Subsidiaries) carries on a trade in the United Kingdom through a permanent establishment in the United Kingdom. Nevertheless, because neither case law nor U.K. statute completely defines the activities that constitute trading in the United Kingdom through a permanent establishment in the United Kingdom, His Majesty's Revenue and Customs ("HMRC") might contend successfully that any of us (other than the U.K. Subsidiaries) are trading in the United Kingdom through a permanent establishment in the United Kingdom.

The United Kingdom has no comprehensive tax treaty with Bermuda. There are circumstances in which companies that are neither tax resident in the United Kingdom nor carrying on a trade in the United Kingdom through a permanent establishment in the United Kingdom (and are therefore not subject to U.K. corporation tax) but are not entitled to the protection afforded by a tax treaty between the United Kingdom and the jurisdiction in which they are a resident may nonetheless be exposed to income tax in the United Kingdom on the profits of a trade carried on there, even if that trade is not carried on through a permanent establishment. However, our non-U.K. entities intend to operate in such a manner that none fall within this charge to income tax in the United Kingdom.

If our non-U.K. entities, other than the U.K. Subsidiaries, were treated as being resident in the United Kingdom for U.K. corporation tax purposes, or as carrying on a trade in the United Kingdom, whether or not through a permanent establishment, our operating results could be materially adversely affected.

**Our U.K. operations may be affected by recent changes in U.K. tax law.**

The U.K. Subsidiaries should be treated as resident in the United Kingdom and accordingly be subject to U.K. tax in respect of their worldwide income and gains. Any change in the basis or rate of U.K. corporation tax or HMRC's practice and interpretation of U.K. tax law could materially adversely affect the business, prospects, financial condition or results of operations of the U.K. resident companies or their ability to provide returns to shareholders. The U.K. corporation tax rate is currently 25%. As part of the measures in the 2024 Autumn Budget (October 30, 2024), the rate of employer national insurance contributions that employers are required to pay in respect of their employees' earnings was increased from 13.8% to 15% of the value of taxable benefits provided to employees, with effect from April 6, 2025.

The Organization for Economic Co-operation and Development ("OECD") published its final reports on Base Erosion and Profit Shifting ("BEPS Reports") in October 2015, containing recommendations on measures to coordinate multilateral action on international tax rules.

The implementation of recommendations arising from the action points comprising BEPS has resulted in significant changes to local tax legislation and international tax treaties over recent years. For example, BEPS has resulted in jurisdictions implementing laws which (among other things): limit deductibility of interest payments; expand the scope of permanent establishments (thereby extending the scope of jurisdictions' taxing rights); counteract hybrid mismatch arrangements; and strengthen "Controlled Foreign Company" rules. U.K. domestic legislation introduced in relation to hybrid mismatches came into effect on January 1, 2017, and legislation to restrict tax deductions for interest expenses of large groups was brought into effect from April 1, 2017.

In addition, domestic law implementation of BEPS has resulted in taxpayers and/or their advisers and intermediaries being required to engage in discussions and disclose information to tax authorities regarding their tax affairs and transactions. Accordingly, Aspen Group may be required to enter into discussions with and provide information to tax authorities which may require the disclosure of transactions and operations of the Aspen Group, in addition to its obligations under the related information reporting measures (including E.U. and other mandatory disclosure regimes, such as Council Directive 2014/107/EU of 9 December 2014 and Council Directive 2018/822 EU of 25 May 2018) (commonly known as "DAC 6") and the U.K. domestic mandatory disclosure regime.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Further reforms have been, and are expected to be made in response to the proposed extensions of BEPS (i.e., BEPS: Pillar One and Two, commonly known as "BEPS 2.0"). For more information, see "—*The OECD's initiative to limit harmful tax competition may result in higher taxation and increased complexity, burden and cost of compliance*." BEPS and BEPS 2.0 may (depending on their final implementation) have a material adverse effect on our intra-group arrangements, our operations, and our results. Relevant to our U.K. Subsidiaries, the U.K. enacted legislation in July 2023 which implements one aspect of Pillar Two (the income inclusion rule imposing top-up tax on a parent entity in respect of the low-taxed income of a constituent entity) via a "multinational top-up tax" ("MTT") together with a "domestic top-up tax" ("DTT"). Broadly, the MTT and DTT will apply to multinational groups with revenues of at least €750 million for accounting periods beginning on or after December 31, 2023. On February 22, 2024, the U.K. enacted amendments to the MTT including new provisions relating to the U.K.'s implementation of an under-taxed payments rule ("UTPR") and a new DTT. On October 30, 2024, the United Kingdom, as part of its autumn budget, announced further updates to the MTT and DTT to implement updates to the OECD's Pillar 2 rules, commentary and administrative guidance in addition to the introduction of the UTPR and DTT, both of which are intended to apply for accounting periods beginning on or after December 31, 2024. The U.K. legislation implementing the BEPS 2.0 reforms is complex, subject to continued consideration, the release of further guidance by the OECD and, in certain cases, update by the U.K. Parliament and in particular may be affected by the implementation (or lack thereof) of similar rules in other jurisdictions in which we operate (for example, see "*—The OECD's initiative to limit harmful tax competition may result in higher taxation and increased complexity, burden and cost of compliance*").

The U.K. diverted profits tax ("DPT") is separate from U.K. corporation tax and is set at a charge 6% higher than the standard rate of corporation tax. The DPT is an anti-avoidance measure aimed at protecting the U.K. tax base against the artificial diversion of profits that are being earned by activities carried out in the United Kingdom but which are not otherwise being taxed in the United Kingdom, in particular as a result of arrangements amongst companies in the same multinational group. The United Kingdom's network of tax treaties does not offer protection from a DPT charge. In the event that the rules apply to certain arrangements, then upfront payment of HMRC's estimate of the deemed tax liability may be required. If any of our U.K. or non-U.K. companies is liable for DPT as a result of intra-group arrangements, this could have a material adverse effect on our results.

The Finance Bill 2025-26 published on December 4, 2025 included updated legislation reforming the UK transfer pricing, permanent establishment and DPT rules,

For accounting periods beginning on or after January 1, 2026, the DPT regime is repealed and replaced by a new Corporation Tax charge known as Unassessed Transfer Pricing Profits (UTPP). While DPT was a standalone tax separate from Corporation Tax, the new UTPP rules are integrated into the mainstream UK Corporation Tax framework. UTPP targets multinational, contrived arrangements that shift profits out of the UK by imposing a 6% penalty tax above the main corporation tax rate on profits that should have been taxed under transfer pricing rules.

The legislation included in Finance Bill 2025-26 implements changes to various aspects of the UK's transfer pricing rules, which are intended to simplify the application of the current legislation, update the rules in line with international standards, reduce compliance obligations on businesses and address areas of potential legislative weakness. The legislation introduces (subject to certain exclusions) a general exemption from UK-UK transfer pricing where both persons are subject to CT at the same rate. HMRC will have the ability to issue a transfer pricing notice to disapply the exemption in order to prevent a loss of tax, and taxpayers will be able to elect to apply transfer pricing should they wish to do so. Other amendments include changes to the participation condition and changes to valuation in relation to cross-border intangibles transactions between related parties. The legislation explicitly confirms that the UK's transfer pricing legislation should be interpreted in accordance with OECD principles.

The Finance Bill 2025-26 includes legislation which aligns the UK domestic definition of a permanent establishment ("PE") with the definition set out in Article 5 of the 2017 OECD Model Tax Convention ("OECD MTC"). This is welcome news particularly given the recent updates to the OECD MTC Commentary that provide greater clarity on the treatment of remote working arrangements. The measure also revises the current domestic legislation on PE profit attribution to align with Article 7 of the OECD MTC, which is supported by the MTC Commentary and the OECD Report on the Attribution of Profits to permanent establishments (AOA). This change only applies for inbound PEs (i.e. non-UK resident companies with UK activities); the Government has not changed the equivalent language for outbound PEs which was a point raised during consultation.

**Our U.K. and U.S. operations may be adversely affected by a transfer pricing adjustment in computing U.K. or U.S. taxable profits.** 

Any arrangements between U.K.-resident entities of the Aspen Group and other members of the Aspen Group are subject to the U.K. transfer pricing regime. Consequently, if any agreement (including any reinsurance agreements) between a U.K.-resident entity of the Aspen Group and any other Aspen Group entity (whether that entity is resident in or outside the United Kingdom) is found not to be on arm's length terms and as a result a U.K. tax advantage is being or has been obtained, an adjustment will be required to compute U.K. taxable profits as if such an agreement were or had been on arm's length terms. Similar rules apply in the United States and would have a similar impact on our U.S. resident entities if transfer pricing adjustments were required. Any transfer pricing adjustment could adversely impact the tax charge suffered by the relevant U.K. or U.S. resident entities of the Aspen Group.

The BEPS Reports included a recommendation that groups should be required to report details of their operations and intra-group transactions in each jurisdiction, known as country by country reporting. The U.K. has implemented these recommendations with effect from January 1, 2016. It is possible that our approach to transfer pricing may become subject to greater scrutiny from the tax authorities in the jurisdictions in which we operate, which may lead to transfer pricing audits in the future. Any transfer pricing adjustment could adversely impact the tax charge suffered by the relevant entities of the Aspen Group.

**Recent and future changes in U.S. federal income tax law or the manner in which it is interpreted could materially adversely affect our results of operations.**

On August 16, 2022, the U.S. government enacted the Inflation Reduction Act of 2022 (the "IRA"). The IRA contains a number of tax-related provisions, including a 15% minimum corporate income tax on certain large corporations as well as an excise tax on certain stock repurchases.

The impact of the IRA on our financial condition will depend on the facts and circumstances of each year. It is possible that other legislation could be introduced and enacted by the current Congress or future Congresses of the United States, or that regulations or other interpretations could be issued, possibly with retroactive effect, that could have an adverse impact on us or our shareholders. These recent and potential future changes in law or interpretation could materially adversely affect our business, access to capital, financial condition and results of operations.

**U.S. persons who hold 10% or more of the total voting power or value of our shares may be subject to U.S. federal income taxation on our undistributed earnings.** 

In general, a "10% U.S. Shareholder" (as defined below) of a non-U.S. corporation that is a controlled foreign corporation ("CFC") at any time during a taxable year must include in its gross income for U.S. federal income tax purposes its pro rata share of the CFC's "subpart F income" and "tested income" (with various adjustments) with respect to any shares that such 10% U.S. Shareholder owns in such non-U.S. corporation (directly or indirectly through certain entities) on the last day in the non-U.S. corporation's taxable year on which it is a CFC, even if the subpart F income or tested income is not distributed. A "10% U.S. Shareholder" generally is a U.S. person that owns (directly, indirectly through non-U.S. entities or by attribution by application of the constructive ownership rules of Section 958(b) of the Code (i.e., "constructively")) at least 10% of the total combined voting power or value of all classes of stock of a non-U.S. corporation. "Subpart F income" of a CFC generally includes "foreign personal holding company income" (such as interest, dividends and other types of passive income), as well as insurance and reinsurance income (including underwriting and investment income), and tested income is generally any income of the CFC other than subpart F income and certain other categories of income. An entity treated as a non-U.S. corporation for U.S. federal income tax purposes generally is considered a CFC if 10% U.S. Shareholders own (directly, indirectly through non-U.S. entities or constructively), in the aggregate, more than 50% of the total combined voting power of all classes of voting stock of that non-U.S. corporation or more than 50% of the total value of all stock of that non-U.S. corporation. However, for the purposes of taking into account insurance income, these 50% thresholds are generally reduced to 25%. Further, special rules apply for purposes of taking into account any related person insurance income ("RPII") of a non-U.S. corporation, as described below.

Whether Aspen Holdings is a CFC for a taxable year will depend upon facts regarding our direct and indirect shareholders, about which we have limited information. Accordingly, no assurance can be provided that Aspen Holdings will not be a CFC. Further, regardless of whether Aspen Holdings is a CFC, most or all of our non-U.S. subsidiaries are generally treated as CFCs because our U.S. subsidiaries generally are treated as constructively owning the stock of our non-U.S. subsidiaries. Accordingly, any 10% U.S. Shareholders of Aspen Holdings may be required to include in gross income for U.S. federal income tax purposes for each taxable year their pro rata shares of all or a portion of the subpart F income and tested income generated by our non-U.S. companies (with various adjustments), regardless of whether any distributions are made to them. Any such 10% U.S. Shareholders should consult their own tax advisors regarding the application of these rules to them.

**U.S. persons who hold our shares may be subject to U.S. federal income taxation at ordinary income rates on their proportionate share of our related person insurance income.**

In general, if a non-U.S. corporation is a "RPII CFC" (as defined below) at any time during a taxable year, a U.S. person who owns (directly or indirectly through certain entities) any shares of the non-U.S. corporation (a "U.S. RPII Shareholder") must include in its gross income for U.S. federal income tax purposes its pro rata share of the non-U.S. corporation's RPII with respect to any shares that such U.S. RPII Shareholder owns (directly or indirectly through certain entities) on the last day in the non-U.S. corporation's taxable year, even if the RPII is not distributed. Further, a U.S. RPII Shareholder's pro rata share of any RPII is determined as if all RPII for the taxable year were distributed proportionately only to U.S. RPII Shareholders on that date but generally may not exceed the U.S. RPII Shareholder's pro rata share of the non-U.S. corporation's earnings and profits for the taxable year. In addition, a U.S. RPII Shareholder is required to comply with certain reporting requirements, regardless of the number of shares owned by the U.S. RPII Shareholder.

For these purposes, a "RPII CFC" is any non-U.S. corporation if, on any day of its taxable year, U.S. RPII Shareholders collectively own (directly, indirectly through non-U.S. entities or constructively) 25% or more of the total combined voting power of all classes of stock of such corporation entitled to vote or 25% or more of the total value of the stock of such corporation. However, the RPII rules generally do not apply with respect to a non-U.S. corporation if either (i) at all times during its taxable year less than 20% of the total combined voting power of all classes of stock of the corporation entitled to vote and less than 20% of the total value of the corporation is owned (directly or indirectly) by persons who are (directly or indirectly) insured under any policy of insurance or reinsurance issued by the corporation or who are related persons to any such person (the "ownership exception"), or (ii) the RPII (determined on a gross basis) of the corporation for the taxable year is less than 20% of its gross insurance income for the taxable year (the "de minimis exception").

We believe that each of our non-U.S. Operating Subsidiaries and Peregrine is a RPII CFC. Nonetheless, we expect that each such company will qualify for one or both of the ownership exception and the de minimis exception in the current taxable year and for the foreseeable future. However, the RPII provisions have never been interpreted by the courts, and regulations interpreting the RPII provisions exist only in proposed form. Certain recently issued proposed regulations would expand the scope of RPII. It is not certain whether any of these regulations will be adopted in their proposed form or what changes or clarifications might ultimately be made thereto or whether any such changes, as well as any interpretation or application of the RPII rules by the IRS, the courts, or otherwise, might have retroactive effect. The U.S. Treasury Department has authority to impose, among other things, additional reporting requirements with respect to RPII. Accordingly, the meaning of the RPII provisions and the application thereof to us is uncertain. Further, the applicability of the ownership and de minimis exceptions and the RPII rules more generally depends upon facts regarding our direct and indirect shareholders and insureds, about which we have limited information. Accordingly, no assurances can be provided that any of our companies will satisfy either exception. Moreover, to the extent the exceptions do not apply, we may be unable to correctly determine the amount of RPII that any U.S. RPII Shareholder is required to take into account.

**U.S. persons who dispose of our shares may be subject to U.S. federal income taxation at the rates applicable to dividends on a portion of such disposition.** 

Section 1248 of the Code may apply to a disposition of our shares. Section 1248 provides that if a U.S. person sells or exchanges stock in a non-U.S. corporation and such person owned, directly, indirectly through certain non-U.S. entities or constructively, 10% or more of the voting power of the corporation at any time during the five-year period ending on the date of disposition when the corporation was a CFC, any gain from the sale or exchange of the shares will be treated as a dividend to the extent of the CFC's earnings and profits (determined under U.S. federal income tax principles) during the period that the shareholder held the shares and while the corporation was a CFC (with certain adjustments). As described above, our bye-laws may reduce the voting power of our shares in certain circumstances, although it is unclear if such reduction would be respected for purposes of Section 1248 of the Code.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Additionally, Section 1248, in conjunction with the RPII rules, generally provides that if a U.S. person disposes of shares in a RPII CFC (determined without regard to the ownership or de minimis exceptions) that would be taxable as an insurance company under the Code if it were a U.S. corporation, any gain from the disposition will generally be treated as a dividend to the extent of the holder's share of the corporation's undistributed earnings and profits that were accumulated during the period that the holder owned the shares (whether or not such earnings and profits are attributable to RPII). In addition, such a holder will be required to comply with certain reporting requirements, regardless of the number of shares owned by the holder. These RPII rules should not apply to dispositions of our shares because Aspen Holdings will not itself be directly engaged in the insurance business. However, as discussed above, there is uncertainty in the interpretation of the RPII provisions and thus no assurances can be provided.

**U.S. persons who hold our shares may be subject to adverse tax consequences if we are considered to be a passive foreign investment company.** 

If Aspen Holdings is characterized as a passive foreign investment company ("PFIC"), a U.S. person holding shares of Aspen Holdings generally would be subject to an increased tax liability at the time of the sale at a gain of, or receipt of an "excess distribution" with respect to, their shares. In addition, if Aspen Holdings is considered a PFIC, upon the death of any U.S. individual owning shares, such individual's heirs or estate would not be entitled to a "step-up" in the basis of the shares that might otherwise be available under U.S. federal income tax laws. Further, a distribution paid by Aspen Holdings to U.S. shareholders that is characterized as a dividend and is not characterized as an excess distribution will not be eligible for reduced rates of tax as qualified dividend income if Aspen Holdings is considered a PFIC in the taxable year in which such dividend is paid or was a PFIC in the preceding taxable year. A U.S. shareholder may also be subject to additional information reporting requirements, including the filing of an IRS Form 8621, if Aspen Holdings is a PFIC. These rules generally will apply to a U.S. person if Aspen Holdings was a PFIC at any time during the U.S. person's holding period with respect to our shares. Different consequences may apply if the U.S. person has elected to treat Aspen Holdings as a "qualified electing fund" or if the U.S. person is a 10% U.S. Shareholder of Aspen Holdings and Aspen Holdings is a CFC.

Further, if Aspen Holdings is considered a PFIC for any taxable year and our shares are treated as "marketable stock" in such year, then a U.S. shareholder may make a mark-to-market election with respect to its shares. The shares will be marketable if they are regularly traded on certain qualifying stock exchanges, including the NYSE. However, there can be no assurance that such election will be available. Additionally, because a mark-to-market election usually cannot be made for any lower-tier PFICs, a U.S. holder will generally continue to be subject to the special tax rules discussed above with respect its indirect interest in any non-U.S. subsidiary of Aspen Holdings classified as a PFIC. As a result, it is possible that any mark-to-market election with respect to our shares will be of limited benefit. In general, if a U.S. holder of our shares were to make a timely and effective mark-to-market election, such holder would include in its taxable income each year the excess, if any, of the fair market value of its shares at the end of the taxable year over its adjusted basis in such shares. Amounts included in taxable income are treated as gains on the sale of the shares and are taxed as ordinary income. Any gain recognized by such holder on the sale or other disposition of our shares would be ordinary income, and any loss would be an ordinary loss to the extent of the net amount of previously included income as a result of the mark-to-market election and, thereafter, a capital loss. U.S. investors are urged to consult with their tax advisors regarding the availability and consequences of making a mark-to-market election with respect to our shares.

In general, a non-U.S. corporation will be a PFIC during a given year if (i) 75% or more of its gross income constitutes "passive income" (the "75% test") or (ii) 50% or more of its assets produce (or are held for the production of) passive income (the "50% test"). For these purposes, passive income generally includes interest, dividends, annuities and other investment income. However, the PFIC provisions contain a look-through rule under which a non-U.S. corporation that directly or indirectly owns at least 25% of the value of the stock of another corporation generally is treated, for purposes of determining whether it is a PFIC, as if it received directly its proportionate share of the income, and held its proportionate share of the assets, of the other corporation (the **"**look-through rule**"**). As a result, it is expected that the PFIC status of Aspen Holdings should generally depend on the application of the look-through rule to its subsidiaries and whether the income and assets of its subsidiaries will be characterized as passive or active for this purpose. In addition, pursuant to an insurance exception, (a) passive income does not include income that a qualifying insurance corporation ("QIC") derives in the active conduct of an insurance business or income of a qualifying domestic insurance corporation ("QDIC") (generally, a U.S. corporation with respect to which the look-through rule applies that is taxable as an insurance company and is subject to U.S. federal income tax on its net income), and (b) passive assets do not include assets of a QIC available to satisfy liabilities of the QIC related to its insurance business, if the QIC is engaged in the active conduct of an insurance business, or assets of a QDIC.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Generally, a non-U.S. corporation will be a QIC for a taxable year if it would be taxable as an insurance company if it were a U.S. corporation and its applicable insurance liabilities constitute more than 25% of its total assets for a taxable year. Further, under recently proposed regulations (the "2021 Proposed Regulations"), a QIC is engaged in the "active conduct" of an insurance business only if it satisfies either a "factual requirements test" or an "active conduct percentage test." The factual requirements test requires that the officers and employees of the QIC carry out substantial managerial and operational activities on a regular and continuous basis with respect to its core functions (generally its underwriting activities, investment activities, contract and claims management activities and sales activities) and that they perform virtually all of the active decision-making functions relevant to underwriting functions. The active conduct percentage test generally requires that (i) the total costs incurred by the QIC with respect to its officers and employees for services rendered with respect to its core functions (other than investment activities) equal or exceed 50% of the total costs incurred by the QIC with respect to its officers and employees and any other person or entities for services rendered with respect to its core functions (other than investment activities) and (ii) to the extent the QIC outsources any part of its core functions to unrelated entities, officers and employees of the QIC with experience and relevant expertise must select and supervise the person that performs the outsourced functions, establish objectives for performance of the outsourced functions and prescribe rigorous guidelines relating to the outsourced functions which are routinely evaluated and updated. Under certain exceptions, however, a QIC that has no or only a nominal number of employees or that is a vehicle that has the effect of securitizing or collateralizing insurance risks underwritten by other insurance or reinsurance companies or is an insurance linked securities fund that invests in securitization vehicles generally is deemed not engaged in the active conduct of an insurance business. The officers and employees of certain related entities generally may be taken into account for these purposes, provided that the QIC exercises regular oversight and supervision over the services performed by the related entity's officers and employees. The 2021 Proposed Regulations will not be effective unless and until adopted in final form, but taxpayers may rely on them for taxable years beginning after December 31, 2017 if they are consistently followed.

We believe that, based on the implementation of our current business plan and the application of the insurance exception, our non-U.S. insurance subsidiaries should be considered QICs engaged in the active conduct of an insurance business under one or both of the "factual requirements test" or the "active conduct percentage test," our U.S. insurance subsidiaries should be considered QDICs and none of the income or assets of such insurance subsidiaries should be treated as passive. In addition, the income and assets attributable to our non-U.S. subsidiaries that are not insurance subsidiaries are minimal, relative to the income and assets attributable to our other subsidiaries. As a result, based on the application of the look-through rule, we believe that Aspen Holdings should not be characterized as a PFIC for the current year or the foreseeable future. However, because of legal uncertainties with respect to the interpretation of the PFIC rules and whether the 2021 Proposed Regulations will be adopted as final regulations in their current form, and factual uncertainties with respect to our planned operations, there is a risk that Aspen Holdings will be characterized as a PFIC in one or more years. If Aspen Holdings is considered a PFIC, it could have material adverse tax consequences for an investor that is subject to U.S. federal income taxation. Prospective investors should consult their tax advisors as to the effects of the PFIC rules on an investment in our shares.

**U.S. tax-exempt organizations who own our shares may recognize unrelated business taxable income.** 

A U.S. tax-exempt organization generally will recognize unrelated business taxable income if the organization is required to include in gross income any of our insurance income under the CFC rules described above (including the RPII provisions). U.S. tax-exempt organizations are advised to consult their own tax advisors regarding the applicability of these rules to their ownership of our shares.

**The OECD's initiative to limit harmful tax competition may result in higher taxation and increased complexity, burden and cost of compliance.**

On December 22, 2021, the European Union published the draft Anti-Tax Avoidance Directive III ("ATAD III") designed to impose new minimum substance rules to prevent the misuse of shell entities for improper tax purposes. ATAD III proposes to introduce reporting requirements for certain E.U. tax resident companies with mobile and/or passive income (such as interest, dividends and royalty income) that have inadequate economic substance (as prescribed under ATAD III). If an entity fails to meet these substance requirements, it will be denied benefits under tax treaties and various E.U. directives. The European Parliament has proposed a number of amendments to ATAD III which, if adopted by the European Council (which it is not obliged to do), would apply the Directive from January 1, 2027. Certain Member States may also seek to implement their own transitional rules. The details of these rules are therefore subject to substantial uncertainty and further change.

In addition, the OECD is continuing to work on a two-pillar initiative, "BEPS 2.0," which is aimed at (1) shifting taxing rights to the jurisdiction of the consumer ("Pillar One") and (2) ensuring all companies pay a global minimum tax ("Pillar Two"). Pillar One will, broadly, re-allocate taxing rights over 25% of the residual profits of multinational enterprises ("MNEs") with global turnover in excess of 20 billion euros (excluding extractives and regulated financial services) to the jurisdictions where the customers and users of those MNEs are located. Pillar Two will, broadly, consist of two interlocking domestic rules (together the Global anti-Base Erosion Rules (the "GloBE Rules")): (i) an Income Inclusion Rule ("IIR"), which imposes top-up tax on a parent entity in respect of the low-taxed income of a constituent entity; and (ii) a UTPR, which denies deductions or requires an equivalent adjustment to the extent the low-taxed income of a constituent entity is not subject to tax under an IIR.

Key aspects of Pillar Two (including IIR regimes) have already become effective in jurisdictions relevant to our business as of January 1, 2024, with other aspects (including UTPR regimes) to become effective in 2025. The OECD continues to release guidance on the implementation and interpretation of its model GloBE Rules for Pillar Two on a rolling basis (some of which have retrospective effect) which may result in further amendments to the Pillar Two rules as they apply in relevant jurisdictions.

Relevant to our U.K. Subsidiaries, as U.K. tax resident entities, the U.K. enacted legislation in July 2023 which implemented the IIR via a "multinational top-up tax" (alongside a U.K. domestic top-up tax) that applies to multinational enterprises for accounting periods beginning on or after December 31, 2023 and is proposing the introduction of a UTPR to be effective for accounting periods beginning on or after December 31, 2024.

Additionally, relevant to our subsidiaries that operate in Singapore and Switzerland, both Singapore and Switzerland enacted legislation which implement the IIR alongside domestic top-up taxes. In Singapore, the "Multinational Enterprise Top-up Tax" (and domestic top-up tax) applies to multinational enterprises for accounting periods beginning on or after January 1, 2025. In Switzerland, the "top-up tax" applies to multinational enterprises for accounting periods beginning on or after January 1, 2025, while the minimum taxation ordinance has applied for accounting periods beginning January 1, 2024. Neither jurisdiction currently proposes the introduction of a UTPR.

Separately, in the European Union the Council Directive (EU) 2022/2523, adopted on December 15, 2022, requires that E.U. Member States implement the Pillar Two rules into domestic law by December 31, 2023, with ultimate application dependent upon implementation by each member state. The Bermuda Government passed the Corporate Income Tax Act 2023 (the "CIT Act"), on December 27, 2023, which introduced a corporate income tax on certain Bermuda entities with effect from January 1, 2025. For more information, see "—*Changes to Bermuda tax policies may impact our financial position*." The implications of this proposal for our business remain uncertain in terms of how the Bermuda corporate income tax regime might interact with the U.K.'s multinational top-up tax and undertaxed payments rule or other Pillar Two implementing legislation in relevant jurisdictions in which we operate, including Singapore and Switzerland. The Bermuda corporate income tax regime became effective for tax years beginning on or after January 1, 2025.

On January 15, 2025, the OECD issued administrative guidance on Article 9.1 of the GloBE Rules (the "OECD 2025 Administrative Guidance"). This guidance, if incorporated into the laws of the jurisdictions in which we operate, could cause additional top-up taxes pursuant to the GloBE Rules to the extent our deferred tax asset in respect of the CIT Act's Economic Transition Adjustments ("ETA") reverses after 2026. Bermuda passed the Corporate Income Tax Amendment (No. 2) Act 2025 in December 2025 to align Bermuda's CIT corporate income tax treatment of deferred tax liabilities with the OECD 2025 Administrative Guidance. It is uncertain whether the other jurisdictions in which we operate will also incorporate this guidance. Further, the amount of such deferred tax asset that reverses in any given year, if any, is uncertain. To the extent the jurisdictions in which we operate incorporate this guidance into their own laws, our overall cash tax savings from the reversal of the deferred tax asset could be limited to the lesser of 20% of the gross deferred tax asset or the portion of the deferred tax asset that reverses in 2025 and 2026.

**Changes to Bermuda tax policies may impact our financial position.** 

We obtained from the Minister of Finance of Bermuda under the Exempted Undertakings Tax Protection Act 1966 (as amended) (the "EUTP Act") an assurance that, in the event Bermuda enacts legislation imposing tax computed on profits, income, any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then the imposition of the tax will not be applicable to us or our operations or to our shares, debentures or other obligations except insofar as such tax applies to persons ordinarily resident in Bermuda or to any taxes payable by us in respect of real property owned or leased by us in Bermuda until March 31, 2035. As a result of changes made to the EUTP Act by the CIT Act, this assurance has been made subject to the application of any taxes pursuant to the CIT Act, as described further below.

The CIT Act (as amended) became fully operative with respect to the imposition of corporate income tax on January 1, 2025.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Under the CIT Act, Bermuda corporate income tax is chargeable in respect of fiscal years beginning on or after January 1, 2025 and applies only to Bermuda Constituent Entities (as defined below) of an In Scope MNE group (as defined below).

*In Scope Entities*

An In Scope MNE Group for these purposes is a group which meets the relevant revenue threshold (EUR 750 million or more in annual revenues in at least two of the four fiscal years immediately preceding the fiscal year in question and is an MNE Group (being a group (as further defined below) comprising an ultimate parent entity and one or more entities (which includes permanent establishments) located in another jurisdiction). For MNE Groups that meet the revenue threshold, corporate income tax generally applies to each Bermuda resident entity and Bermuda permanent establishment that is a constituent entity of such MNE Group (a Bermuda Constituent Entity). Consistent with the GloBE Rules, the terms "group", "ultimate parent entity" and "controlling interest" and critical to determining whether a Bermuda entity is considered a constituent entity of an MNE Group.

A "group" is defined for the purposes of the CIT Act as (a) a collection of entities that are related through ownership or control such that the assets, liabilities, income, expenses and cash flows of those entities are included in the consolidated financial statements of the ultimate parent entity, or are excluded from the consolidated financial statements of the ultimate parent entity solely on size or materiality grounds, or on the grounds that the entity is held for sale; or (b) an entity that is located in one jurisdiction and has one or more permanent establishments located in other jurisdictions provided that the entity is not part of another group as described in (a) above.

An "ultimate parent entity" is (a) an entity that owns, directly or indirectly, a controlling interest in any entity, and is not owned, with a controlling interest, directly or indirectly by another entity; or (b) with respect to permanent establishments, the main entity in a group, being the entity that includes the financial accounting net income or loss of a permanent establishment in its financial statements. A "controlling interest" is an ownership interest in any entity such that the interest holder (a) is required to consolidate the assets, liabilities, income, expenses and cash flows of the entity on a line-by-line basis in accordance with an acceptable accounting standard, or (b) would have been required to consolidate the assets, liabilities, income, expenses and cash flows of the entity on a line-by-line basis if the interest holder has prepared consolidated financial statements, provided with respect to permanent establishments, that a main entity is deemed to have the controlling interests of its permanent establishments.

In practical terms, therefore, Bermuda resident entities are only within the scope of Bermuda corporate income tax as Bermuda Constituent Entities if either they are consolidated on a line by line basis in the consolidated financial statements (prepared in accordance with an acceptable financial accounting standard) (or would be if consolidated financial statements had been prepared under an acceptable financial accounting standard) of an ultimate parent entity located in another jurisdiction; or the Bermuda resident entity or entities themselves consolidate on a line by line basis the results of one or more entities located in another jurisdiction in consolidated financial statements, and in either case the group meets the relevant revenue threshold. Where consolidated financial statements are prepared on a basis that does not consolidate line by line, there is no "controlling interest" and therefore no "ultimate parent entity", meaning that there is no MNE Group for the purposes of the CIT Act. Accordingly, Bermuda resident entities that are not consolidated on a line-by-line basis or do not consolidate on a line-by-line basis (nor would be required if consolidated financial statements had been prepared under an acceptable financial accounting standard) will not be considered in scope for the purposes of the Act. It is expected that the Company will be in scope for the purposes of the CIT Act and that, as at December 31, 2025, the Company and its subsidiaries are expected to be an In Scope MNE Group.

*Bermuda Constituent Entity Groups*

Where a Bermuda entity or Bermuda permanent establishment is a Bermuda Constituent Entity, corporate income tax is chargeable in respect of fiscal years beginning on or after January 1, 2025 to the Bermuda Constituent Entity Group. A Bermuda Constituent Entity Group is a group comprised of one or more Bermuda Constituent Entities that are members of an In Scope MNE Group. It is possible for an In Scope MNE Group to include more than one Bermuda Constituent Entity Group and specific rules apply. For example, companies incorporated under the Companies Act 1981 which are registered under the Segregated Accounts Companies Act 2000 are regarded as a single entity which is not fiscally transparent. However, a Bermuda Constituent Entity may elect to treat any segregated accounts within such entity as separate Bermuda Constituent Entities, and if such an election is made, may further elect to treat any given segregated account as fiscally transparent or not. Such elections are annual elections which apply for the fiscal year in which the election is made and all subsequent fiscal years, unless and until the election is modified or revoked.

*Chargeable Corporate Income Tax*

Where corporate income tax is chargeable to a Bermuda Constituent Entity Group, the amount of corporate income tax chargeable for a fiscal year shall be (a) 15% of the net taxable income of the Bermuda Constituent Entity Group; less (b) tax credits applicable to the Bermuda Constituent Entity Group under Part 4 of the CIT Act, or as prescribed.

Detailed rules apply with respect to the calculation of net taxable income of each Bermuda Constituent Entity in a Bermuda Constituent Entity Group. Adjustments include deductions for brought forward losses incurred in prior years, certain excluded dividends, modifications for stock-based compensation, intra-group transactions etc.

As at December 31, 2025, we have adjusted our deferred tax calculated in the prior year, 2024, to account for provisions within the CIT Act that allow for an equitable transition to the new regime including the ETA and opening tax loss carryforward ("OTLC"). Our deferred tax asset in Bermuda consists of $145.7 million in respect of the ETA and $44.2 million in respect of an OTLC. We expect this deferred tax asset to be utilized predominantly over a 10-year period.

*Updates to Corporate Income Tax Regime*

In May 2025, Bermuda released final Corporate Income Tax (Administrative) Regulations 2025 (the "CIT Regulations"), which clarify how the corporate income tax regime will be administered, including registration, filing and payment deadlines, and procedures for enquiries and assessments. The CIT Regulations took effect 2 June 2025 and are an important part of the operational framework of the new tax regime.

In December 2025, the Bermuda Parliament enacted the Tax Credits Act 2025 (the "Credits Act") and the Corporate Income Tax Amendment (No. 2) Act 2025 (the "Amendment Act"). The Credits Act establishes new tax credits including substance-based, community development, and utilities infrastructure credits for fiscal years beginning on or after 1 January 2025, designed to support economic activity and investment. The Amendment Act introduces targeted technical refinements and strengthens the integration of the corporate income tax regime with the new tax credit framework, reflecting stakeholder feedback from consultations conducted through 2025.

Throughout 2025, Bermuda's Corporate Income Tax Agency conducted multiple public consultations on proposed technical amendments to clarify and better align certain provisions of the CIT Act with global tax standards (e.g., GloBE rules), including treatment of losses, excluded entities, tax allocation rules, and other definitions, though these were proposals subject to legislative finalization. More broadly, Bermuda remains committed to tax transparency, which is evidenced by adopting economic substance legislation, which has been deemed compliant by the European Union and was designed to implement the work of the Forum on Harmful Tax Practices under Action 5 of the OECD's BEPS Reports. Any changes in the tax law of an OECD member state or in response to a change in E.U. policies could subject us to additional taxes, and we are unable to predict at this time whether it would have a material adverse impact on our operations and results. More broadly, Bermuda remains committed to tax transparency, which is evidenced by adopting economic substance legislation, which has been deemed compliant by the European Union and was designed to implement the work of the Forum on Harmful Tax Practices under Action 5 of the OECD's BEPS Reports. Any changes in the tax law of an OECD member state or in response to a change in E.U. policies could subject us to additional taxes, and we are unable to predict at this time whether it would have a material adverse impact on our operations and results.

**Item 4. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Information on the Company**

&nbsp;&nbsp;&nbsp;&nbsp;**A. History and Development of the Company** 

Aspen Insurance Holdings Limited ("Aspen Holdings") was incorporated as a Bermuda exempted company on May 23, 2002 as a holding company headquartered in Bermuda. We underwrite specialty insurance and reinsurance on a global basis through our Operating Subsidiaries (as defined below) based in Bermuda, the United States and the United Kingdom: Aspen Bermuda Limited ("Aspen Bermuda"), Aspen Specialty Insurance Company ("Aspen Specialty"), Aspen American Insurance Company ("AAIC"), Aspen Insurance UK Limited ("Aspen UK") and Aspen Underwriting Limited ("AUL") (as the sole corporate member of our Lloyd's operations, Syndicate 4711, which is managed by Aspen Managing Agency Limited ("AMAL") (together, "Aspen Lloyd's")), each referred to herein as an "Operating Subsidiary" and collectively referred to as the "Operating Subsidiaries", as well as through branch operations in Canada, Singapore and Switzerland. The principal office is located at Waterloo House, 100 Pitts Bay Road, Pembroke HM08, Bermuda (telephone number: +1 441-278-0400).

From February 2019 until May 2025, the Company was a wholly-owned subsidiary of Highlands Bermuda Holdco, Ltd. which held all of the Company's issued and outstanding Class A ordinary shares, par value $0.001 per share (the "Ordinary Shares") and is an affiliate of certain investment funds managed by affiliates of Apollo Global Management, Inc., a leading global investment manager (collectively with its subsidiaries, "Apollo"). Immediately prior to the Company's initial public offering in May 2025 ("IPO"), Highlands Bermuda Holdco, Ltd. distributed all of the Company's issued and outstanding Ordinary Shares to AP Highlands Holdings, L.P., a Cayman exempted limited partnership, and AP Highlands Co-Invest, L.P., a Cayman exempted limited partnership (together, the "Apollo Shareholders"), as well as certain other individuals. The Apollo Shareholders are each an affiliate of certain investment funds managed by affiliates of Apollo.

In May 2025, the Company completed its IPO of 13,250,000 of its Ordinary Shares. The Ordinary Shares began trading on the New York Stock Exchange ("NYSE") on May 8, 2025. Subsequent to the closing of the IPO, the underwriters exercised in full the option to purchase up to an additional 1,987,500 of the Company's Ordinary Shares. The shares sold in the IPO were sold by the Apollo Shareholders, and the Company did not receive any of the proceeds from the sale of the Ordinary Shares by the Apollo Shareholders. Following the completion of these matters, the Apollo Shareholders collectively beneficially owned approximately 82.1% of the Company's Ordinary Shares.

**Acquisition by Sompo** 

On February 24, 2026, Aspen was acquired by a wholly-owned indirect subsidiary of Sompo, a leading global provider of commercial and consumer property and casualty (re)insurance. For more information regarding the Merger, refer to the "*Explanatory Note*" on page 2 of this report, Item 5, "*Operating and Financial Review and Prospects, Operating Results*"and Note 1 of our consolidated financial statements, *"History, Organization and Business Combination."* 

The Company maintains a website at www.sompo-intl.com. The information on our website is not incorporated by reference in this report. We make available, free of charge through our website, our Annual Reports on Form 20-F and other reports filed or furnished pursuant to Section 13(a) or 15(d) of the Exchange Act as soon as reasonably practicable after we electronically file such material with, or furnish such material to, the SEC.

The SEC maintains a website at www.sec.gov that contains reports and other information regarding issuers, including the Company, that file electronically with the SEC.

&nbsp;&nbsp;&nbsp;&nbsp;**B. Business Overview**

We are a Bermuda-based holding company, whose principal business is marketing and underwriting specialty insurance and reinsurance on a global basis. Our business is comprised of: (i) underwriting operations, which includes our risk-bearing insurance and reinsurance operations; (ii) investing activities, which primarily support our underwriting operations; and (iii) our ACM operations, which earn underwriting, management and performance fees from the Company and other third-party investors primarily through the management of insurance linked securities ("ILS") funds and other offerings. ACM forms part of the Aspen Capital Partners platform, in recognition of the synergies between ACM and the Company's ceded reinsurance teams, which together support our underwriting operations.

We manage our underwriting operations as two distinct business segments, Insurance ("Aspen Insurance") and Reinsurance ("Aspen Re"), to enhance and better serve our global customer base. Financial data relating to our two business segments is included in Item 5, "Operating and Financial Review and Prospects" and in Item 18, Note 3 of our consolidated financial statements, "Segment Reporting."

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Aspen Insurance* 

Aspen Insurance offers a variety of insurance products, including, but not limited to: (i) first party insurance, (ii) specialty insurance, (iii) casualty and liability insurance, (iv) financial and professional lines insurance, and (v) other insurance, which represents the participation of Aspen Lloyd's as corporate member in Carbon Syndicate 4747 and the Company's digital follow capacity offered through Ki Lloyd's platforms.

In our Insurance segment, these products are written in the London Market primarily by Aspen UK and Aspen Lloyd's via the Lloyd's platform and, in the United States, by AAIC and Aspen Specialty (on an admitted and excess and surplus line, basis, respectively). We also write casualty and liability and financial and professional lines business through Aspen Bermuda. Although our products are underwritten according to the guidelines associated with each local entity, our insurance business is managed globally with individual product lines grouped and managed into four select portfolios. This allows for consistency of underwriting appetite, risk selection and application of underwriting guidelines across all our jurisdictions, as well as providing opportunities for integrated marketing and relationship management efforts.

*Aspen Re* 

Aspen Re offers a variety of reinsurance and retrocession products, including, but not limited to: (i) property catastrophe reinsurance, (ii) other property reinsurance, (iii) casualty reinsurance, and (iv) specialty reinsurance. We offer reinsurance on both a treaty and facultative basis, and on both a proportional (such as quota share) and non-proportional (such as excess of loss) basis.

Our reinsurance business is sourced principally through brokers and reinsurance intermediaries, with whom we aim to maintain strong relationships, having become a valued risk management partner to the leading insurers with whom we do business. We write property catastrophe, property, casualty and specialty reinsurance business through Aspen Bermuda and its branches in Singapore and Switzerland, Aspen Lloyd's and AAIC. We also access the EEA market through Lloyd's Insurance Company, which is 100% reinsured by Syndicate 4711.

Across both Aspen Insurance and Aspen Re, in several of our product lines, business consists of a combination of open market and business written pursuant to Delegated Underwriting Authorities ("DUA") or Programs arrangements, or through managing agents or other agents.

*Investments* 

Our investment strategy seeks to deliver stable investment income and total return through all market cycles while maintaining appropriate portfolio liquidity and credit quality to meet the requirements of our customers, rating agencies and regulators. Income from our investment operations is included in corporate and other (non-operating) income and expenses.

*Aspen Capital Markets* 

We participate in the alternative reinsurance market through ACM, which acts as a conduit between Aspen's balance sheet and third-party investors and supports each of our Insurance and Reinsurance segments. ACM sources third-party capital and develops reinsurance structures that leverage the Company's underwriting and analytical expertise and earns underwriting, management and performance fees from third-party investors primarily through the placement and management of collateralized quota share sidecar vehicles, insurance linked securities ("ILS") funds and other offerings. It operates primarily two distinct strategies, namely, building insurance risk portfolios tailored to investor objectives through capital sourced by Aspen Capital Management Ltd. ("ACML"), a Bermuda domiciled insurance manager and agent registered with the BMA, and strategically structuring and placing defined Aspen portfolios aligned with capital markets investors through the use of sidecars, including Peregrine Reinsurance Ltd. ("Peregrine"), a special purpose insurer. For more information on Peregrine, see "*Certain Regulatory Considerations—Bermuda Insurance Regulation—Peregrine*" below.

Aspen recognized the synergies between ACM and its Ceded Reinsurance teams – combining the two into Aspen Capital Partners. This move allows us to further enable our trading partners to access the full breadth of Aspen's capabilities, including risk sourcing, underwriting, modelling, actuarial and claims.

Income from ACM's activities is primarily allocated to the line of business being ceded within Aspen's current two segments, Aspen Insurance and Aspen Re, and serves to reduce acquisition expenses for that business and applicable operating entity. While ACM has initially focused on property catastrophe business, it has expanded to provide capacity for property insurance and reinsurance, specialty reinsurance and casualty insurance and reinsurance.

**Business Segments** 

We have determined our reportable segments, Aspen Insurance and Aspen Re, by taking into account the manner in which management makes operating decisions and assesses operating performance. Profit or loss for each of the business segments is measured by underwriting income or loss. Underwriting profit 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.

Management measures segment results on the basis of the combined ratio, which is obtained by dividing the sum of the losses and loss expenses, acquisition costs and general and administrative expenses by net earned premiums.

We provide additional disclosures for corporate and other (non-operating) income and expenses. Corporate and other income and expenses include: corporate expenses, non-operating expense, net investment income, net realized and unrealized investment gains or losses, changes in fair value of derivatives, interest expenses, net realized and unrealized foreign exchange gains or losses, and income taxes. These income and expense items are not allocated to our business segments as they are not directly related to our business segment operations and is consistent with how management measures the performance of its segments. We do not allocate our assets by business segments as we evaluate underwriting results of each segment separately from the results of our investment portfolio.

The table below sets forth the gross written premiums by business segment for the twelve months ended December 31, 2025, 2024 and 2023:

***Financial and Professional Lines Insurance:*** Our financial and professional lines consists of professional liability, management liability, cyber liability, cross class binders, and surety risks written on a primary, excess, quota share, program and facultative basis.

*Professional Liability:* Our professional liability business is written out of the United States (including errors and omissions ("E&O")), the United Kingdom and Bermuda and is written on both a primary and excess of loss basis. We insure a wide range of professions including lawyers, accountants, architects, engineers, doctors and medical technicians. This account may also extend coverage for cyber liability and data protection insurance. The cyber liability and data protection insurance covers firms for first party costs and third-party liabilities associated with cybersecurity breach and breach of contractual or statutory data protection obligations.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Management Liability:* Our management liability business is written out of the United States, the United Kingdom and Bermuda. We insure a diverse group of commercial and financial institutions predominantly on an excess basis. Our products include directors' and officers' ("D&O") liability, fiduciary liability, employment practices liability, fidelity insurance and blended liability programs including E&O liability. The focus of the account is predominantly on risks headquartered in the U.S. or risks with a material U.S. exposure.

Our privacy and network security liability products provide first party costs and third-party liabilities associated with privacy and cybersecurity breaches. Our technology liability product provides coverage for technology, media and telecommunications firms offering protection for damages and legal defense expenses associated with financial loss claims from third parties and various forms of intellectual property breaches. We also incorporate data protection indemnity insurance against costs and liabilities that may arise when a company breaches its data protection obligations.

*Cross Class Binders*: Our cross class binders business is written out of the United States and the United Kingdom via several strategic (re)insurance partnerships. Cross class binders has several multi-product offerings across first party insurance, specialty insurance, casualty and liability insurance, and financial and professional lines insurance.

*Surety Risks:* In July 2020, we sold our renewal rights to our surety insurance book of business to a third party and executed a loss portfolio transfer transaction for the transfer of prior-year liabilities. Pursuant to the terms of the sale transaction, Aspen UK continues to underwrite only a small portion of surety business on a fronted basis to the purchaser in the transaction, which is subject to a 100% quota share reinsurance agreement.

***Casualty and Liability Insurance:*** Our casualty and liability line consists of commercial liability, U.S. primary casualty, excess casualty, environmental liability and railroad liability, written on a primary, excess, quota share, program and facultative basis.

*Commercial Liability*: Commercial liability is primarily written in the United Kingdom and provides employers' liability coverage, products and public liability coverage for insureds domiciled in the United Kingdom and Ireland. The U.K. regional team also covers D&O and professional indemnity, predominantly to small and medium corporates*.*

*U.S. Primary Casualty:* The U.S. primary casualty account consists primarily of lines written within the primary insurance sectors. We are focused on delivering expertise to brokers and customers in hospitality, real estate, construction and products liability.

*Excess Casualty:* The excess casualty line comprises medium and large, sophisticated and risk-managed insureds worldwide and covers broad-based risks at lead/high excess attachment points, including general liability, commercial and residential construction liability, life science, railroads, trucking, product and public liability and associated types of cover found in general liability policies in the global insurance market, written from the United Kingdom, the United States and Bermuda.

*Environmental Liability:* The environmental account primarily provides contractors' pollution liability and pollution legal liability across industry segments that have environmental regulatory drivers and contractual requirements for coverage, including real estate and public entities, contractors and engineers, energy contractors and environmental contractors and consultants. The business is written in both the primary and excess insurance markets in the United States, Canada and the United Kingdom.

*Railroad Liability:* Our railroad liability business consists of primary and excess liability business for freight, commuter and excursion railroads. It also provides general liability coverage to the railroad support industry (contractors, repair shops and products manufacturers) as well as contingent liability for railcar fleet owners/managers and railroad protective liability in the United States.

***Specialty Insurance***: Our specialty insurance line consists of U.K. commercial property, specie, marine and energy liability, onshore energy physical damage, offshore energy physical damage, credit and political risks, and crisis management written on a primary, excess, quota share, program and facultative basis.

*U.K. Commercial Property & Construction:* Property insurance provides physical damage and business interruption coverage for losses arising from weather, fire, theft and other causes. The U.K. commercial team's client base is predominantly U.K. institutional property owners, small and middle market corporates and public sector clients.

*Specie:* The specie business line focuses on the insurance of high value property items on an all risks basis, including fine art, general and bank related specie, jewelers' block and armored car.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Marine and Energy Liability:* In February 2020, we made the decision to cease writing marine and energy liability business and the business was put into runoff. Prior to that, the marine and energy liability business was based in the U.K. and included marine liability cover mainly related to the liabilities of ship-owners and port operators, including reinsurance of Protection and Indemnity Clubs. It also provided liability cover globally (including the U.S.) for companies in the oil and gas sector, both onshore and offshore and in the power generation sector. This class also included commercial construction liability for U.S. companies in the oil and gas sector, which is now being written under our global excess casualty line.

*Natural Resources and Construction:* Our natural resources and construction unit underwrites a variety of worldwide onshore energy and offshore energy, alongside the construction sector with a focus on property covers.

*Credit and Political Risks:* The credit and political risks team writes business covering the credit and contract frustration risks on a variety of trade and non-trade related transactions, as well as political risks (including multi-year war on land cover). We provide credit and political risks cover worldwide but with concentrations in a number of countries, such as China, Brazil, the Netherlands and the United States.

*Crisis Management:* The crisis management team writes insurance designed to protect individuals and corporations operating in high-risk areas around the world, including covering the shipping industry's exposure to acts of piracy. It also writes terrorism, active assailant and political violence insurance, providing coverage for damage to property and liability resulting from random acts of violence, terrorism, strikes, riots, civil commotion or political violence. This book is written on a global basis, although capacity is selectively deployed.

***First Party Insurance:*** Our first party insurance line consists of U.S. property and inland and ocean marine written on a primary, excess, quota share, program and facultative basis.

*U.S. Property:* Property insurance provides physical damage and business interruption coverage for losses arising from weather, fire, theft and other causes. The U.S. property team covers mercantile, manufacturing, municipal and commercial real estate business.

*Inland and Ocean Marine*: The inland and ocean marine team writes business principally covering builders' construction risk, contractors' equipment, renewable energy projects and global transportation exposures such as marine cargo and hull, inland transit, warehousing and war, in addition to exhibition, fine arts and museums insurance. The book also includes business generated by our subsidiary, Blue Waters Insurers, Corp., which acts as our managing general agent in Puerto Rico and produces inland, ocean marine and cargo business in Puerto Rico.

***Other Insurance:*** Our other insurance line includes Aspen Underwriting Limited's participation as a corporate member in Carbon Syndicate 4747, and our partnership with Ki Syndicate 1618. Carbon Syndicate 4747 provides (re)insurance products covering property and third-party liability. Our partnership with Ki offers digitally underwritten follow capacity for insurance products covering Property, Casualty, and Specialty insurance.

On a significant portion of our insurance contracts across all our sub-segments, we are obligated to offer terrorism coverage under TRIA. Wherever possible, we exclude coverage protection against nuclear, biological, chemical or radiological ("NBCR") attacks. However, certain U.S. states (notably New York and Florida) prohibit admitted insurance companies, such as AAIC, from fully excluding such perils, resulting in some level of exposures to NBCR as well as fire following such events. We would expect to benefit from the protection of TRIA and the over-arching $100 billion industry loss cap (subject to the relevant deductible and co-retention).

***Casualty Reinsurance****:* Casualty reinsurance is written on an excess of loss, proportional and facultative basis and consists of U.S. treaty, international treaty and casualty facultative reinsurance. Our treaty business comprises exposures to workers' compensation (including catastrophe), medical malpractice, general liability, auto liability, professional liability and excess liability including umbrella liability. Our facultative business reinsures mainly auto liability and general liability exposures.

***Property Catastrophe Reinsurance****:* Property catastrophe reinsurance is generally written on a treaty excess of loss basis where we provide protection to an insurer for an agreed portion of the total losses from a single event in excess of a specified loss amount. In the event of a loss, most contracts provide for coverage of a second occurrence following the payment of a premium to reinstate the coverage under the contract, which is referred to as a reinstatement premium. The coverage provided under excess of loss reinsurance contracts may be on a worldwide basis or limited in scope to selected regions or geographical areas.

***Other Property Reinsurance****:* Other property reinsurance includes property risks written on excess of loss and proportional treaties, facultative or single risk reinsurance. Risk excess of loss reinsurance provides coverage to a reinsured where it experiences a loss in excess of its retention level on a single "risk" basis. A "risk" in this context might mean the insurance coverage on one building or a group of buildings for fire or explosion or the insurance coverage under a single policy which the reinsured treats as a single risk. This line of business is generally less exposed to accumulations of exposures and losses but can still be impacted by catastrophes, such as earthquakes and hurricanes. Proportional treaty reinsurance provides proportional coverage to the reinsured, meaning that, subject to event limits where applicable and ceding commissions, we pay the same share of the covered original losses as we receive in premiums charged for the covered risks. Proportional contracts typically involve close client relationships which often include regular audits of the cedants' data.

A high percentage of the property catastrophe reinsurance contracts we write exclude or limit coverage for losses arising from the peril of terrorism. Within the U.S., our other property reinsurance contracts generally include limited coverage for acts that are certified as "acts of terrorism" by the U.S. Treasury Department under the Terrorism Risk Insurance Act (including its various extensions, "TRIA"). We have written a limited number of property reinsurance contracts, both on a pro rata and excess of loss basis, specifically covering the peril of terrorism. These contracts typically exclude coverage for nuclear, biological, chemical or radiological attack, though we have written a small number of contracts that do not exclude coverage for such attacks, the coverage of which may be applicable to non-terrorism events.

***Specialty Reinsurance****:* Specialty reinsurance is written on an excess of loss and proportional basis and consists of mortgage reinsurance, marine, energy, technical lines (including nuclear and contingency), agriculture, terrorism, health and other specialty lines. Our specialty agricultural reinsurance business covers crop and multi-peril business. Other specialty lines include reinsurance treaties and some insurance policies covering policyholders' interests in marine, energy, contingency, terrorism, engineering, nuclear, medical expense and personal accident. Aspen ceased writing new and renewal reinsurance for the aviation, space and bloodstock business lines from October 2022.

**Underwriting and Reinsurance Purchasing** 

Our objective is to create a diversified portfolio of insurance and reinsurance risks, spread across lines of business, products, geographic areas of coverage, cedants and sources. The acceptance of appropriately priced risk is the core of our business. Underwriting requires judgment, based on important assumptions about matters that are inherently unpredictable and beyond our control, and for which historical experience and probability analysis may not provide sufficient guidance. We view underwriting quality and risk management as critical to our success.

*Underwriting.* We underwrite according to the following principles:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• strive to build a diverse portfolio of risk that generates attractive returns by deploying capital in a targeted and efficient manner to deliver enhanced underwriting profitability;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operate within agreed boundaries as defined by the business plan for the relevant class of business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operate within prescribed maximum underwriting authority limits, which we delegate to individual underwriters in accordance with an understanding of each individual underwriter's capabilities, tailored to the classes of business written by the particular underwriter;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• evaluate the underlying data provided by clients and adjust such data where we believe it does not adequately reflect the underlying exposure;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• price each submission based on our experience in the class of business, and where appropriate, by deploying one or more actuarial models either developed internally or licensed from third-party providers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain a peer review process to sustain high standards of underwriting discipline and consistency and a sampling methodology for simpler insurance risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• engage in peer reviews for more complex risk by several underwriters and input from catastrophe risk management specialists, our team of actuaries and senior management; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• refer risks outside of agreed underwriting authority limits to the Group Underwriting Committee or relevant entity executive or board of directors as exceptions for approval before we accept the risks.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Reinsurance Purchasing.* We purchase reinsurance and retrocession to mitigate and diversify our risk exposure to a level consistent with our risk appetite and to increase our insurance and reinsurance underwriting capacity. These agreements provide for recovery of a portion of our losses and loss adjustment expenses from our reinsurers. The amount and type of reinsurance that we purchase varies from year to year and is dependent on a variety of factors, including, but not limited to, the cost and terms of a particular reinsurance contract and the nature of our gross exposures assumed, with the aim of securing cost-effective protection. We have a centralized ceded reinsurance department which coordinates the placement of all of our treaty reinsurance placements.

We have reinsurance covers in place for the majority of our insurance classes of business on an excess-of-loss basis and/or proportional treaty basis. The excess of loss covers provide protection in various layers and excess of varying attachment points according to the scope of cover provided. The proportional cover provides protection on the basis of a percentage sharing of both premiums and claims with the reinsurer (known as quota share reinsurance).

With respect to natural perils coverage, we buy protections that cover both our insurance and reinsurance lines of business through a variety of products, including, but not limited to, excess of loss reinsurance, facultative reinsurance, aggregate covers, whole account covers and collateralized products which can be on either an indemnity or an index linked basis. For example, we may purchase industry loss warranty reinsurance which provides retrocessional coverage when insurance industry losses for a defined event exceed a certain level. We expect the type and level of coverage that we purchase will vary over time, reflecting our view of the changing dynamics of the underlying exposure and the reinsurance markets. We manage our risk by seeking to limit the amount of exposure assumed from any one reinsured and the amount of the aggregate exposure to catastrophe losses from a single event in any one geographical zone. Additionally, Aspen Re continues to purchase quota share and retrocessional reinsurance protection for a range of international perils and worldwide catastrophe losses through ACM and other collateralized reinsurance arrangements.

Although reinsurance agreements contractually obligate our reinsurers to reimburse us for an agreed-upon portion of our gross paid losses, we remain liable to our insureds to the extent that our reinsurers do not meet their obligations under these agreements. As a result, and in line with our risk management objectives, we evaluate the financial condition of our reinsurers and monitor concentrations of credit risk on an on-going basis. In general, we seek to place our reinsurance with highly rated companies with which we have a strong trading relationship or have fully collateralized arrangements in place. We maintain a list of authorized reinsurers graded for short, medium and long-tail business which is regularly reviewed and updated.

In January 2022, Aspen Holdings and certain of its subsidiaries entered into the LPT, which amended and restated the Adverse Development Cover Agreement, dated as of March 2, 2020, previously entered into between Enstar and the Aspen Group (the "Original Agreement"). The LPT transaction successfully closed in May 2022.

Under the terms of the LPT, Enstar's subsidiary will reinsure net losses incurred on or prior to December 31, 2019 on all of the Company's net loss reserves of $3,120.0 million as of September 30, 2021. The LPT provides for a limit of $3,570.0 million in consideration for a premium of $3,160.0 million. The amount of net loss reserves ceded, as well as the premium and limit amounts provided under the LPT, have been adjusted for claims paid between October 1, 2021 and the closing date of the transaction. The premium includes $2,610.1 million of premium previously paid with respect to reserves ceded under the Original Agreement, which will continue to be held in trust accounts to secure the Enstar subsidiary's obligations under the LPT. The incremental new premium will initially be held in funds withheld accounts in their original currencies maintained by the Company but will be released to the trust accounts maintained by the Enstar subsidiary no later than September 30, 2025. The funds withheld by the Company will be credited with interest at an annual rate of 1.75% plus, for periods after October 1, 2022, an additional amount equal to 50% of the amount by which the total return on the Company's investments and cash and cash equivalents exceeds 1.75%. Under the LPT, the Enstar subsidiary has assumed claims control of the subject business, pursuant to the provisions of an administrative services agreement subsequently entered into between the parties in June 2022.

For further information regarding the LPT, please refer to Item 4, "*Information on the Company" – "Legal Proceedings*."

**Risk Management** 

Aspen has a comprehensive risk management framework that defines the corporate risk appetite, risk strategy and the policies in place to monitor, manage and mitigate the risk inherent in our business. Our risk management framework covers all risks in our risk universe, on a current and forward-looking basis, and is implemented in a consistent manner across the Aspen Group. It is the basis through which we protect our franchise value and seek to enable sustained profitable growth. Below is a summary of our current corporate governance bodies and risk management strategy:

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

<u>Risk Governance</u> 

*Board of Directors.* The Company's Board of Directors (the "Board") considers effective identification, measurement, monitoring, management and reporting of the risks facing our business to be key elements of its responsibilities and those of the Chief Executive Officer and management. Matters relating to risk management that are reserved for the Board include approval of the internal controls and risk management framework and any changes to the Aspen Group's risk appetite statement and key risk limits. The Risk Committee of the Board received regular reports at each scheduled meeting, or more frequently as needed, covering risk management processes, which include, among others, the design, operation, use and limitations of the internal model. The internal model is an economic capital model which has been developed internally for use in certain business decision-making processes, the assessment of risk-based capital requirements and for various regulatory purposes. As a result of these arrangements and processes, the Board, assisted by management and the various standing committees of the Board (the "Board Committees"), is able to exercise effective oversight of the operation of the risk management strategy described in "— *Risk Management Strategy*" below.

As at December 31, 2025 and through to the effective date of the Merger, the Board delegated oversight of the management of certain key risks to its Risk, Audit, Investment, Conflicts, Compensation and Nominating and Corporate Governance committees (together, the "Board Committees"). The Audit and Conflicts Committees were comprised entirely of independent directors and all Board Committees are structured to ensure appropriate and objective challenge of, and discussion with, management. The chairs of the Board Committees report regularly to the Board on the committees' discussions, and in any event at each of the regular meetings of the Board. In addition, the Board Committees may facilitate informational calls with management from time to time where required and in accordance with the Company's operating guidelines.

In connection with the Merger, the Investment Committee, Conflicts Committee, Compensation Committee and the Nominating and Corporate Governance Committee were dissolved in February 2026.

*Risk Committee*: The Risk Committee assisted the Board in its oversight of the framework that governs risk management and solvency assessment practices group-wide as articulated in the Board approved Group Risk Policy. This specifically included oversight of processes undertaken by management to identify, evaluate and mitigate the material risks to the Group's strategic objectives, as well as monitoring adherence to the Board approved Risk Appetite Framework, solvency indicators, risk tolerance criteria, and key risk limits. The matters considered by the Risk Committee included cybersecurity trends and events as well as general compliance and data privacy matters. For more information regarding oversight of cybersecurity risks, refer to Item 16K, "*Cybersecurit*y."

*Audit Committee:* The Audit Committee is primarily responsible for assisting the Board in its oversight of the integrity of the financial statements. The Audit Committee is also responsible for reviewing the adequacy and effectiveness of the Company's internal controls, relating to the accounting and financial reporting process of the Company and audits of the Company's financial statements, and oversight of both internal and external auditors. In addition, the Audit Committee oversees the Company's compliance with applicable laws and regulations, as well as related party and conflict of interest matters (to the extent not within the remit of the Conflicts Committee). The members of the Audit Committee regularly meet with management, the Internal Audit function and the Company's independent, registered public accounting firm to review matters relating to the quality of financial reporting and internal accounting controls, including the nature, extent and results of their audit.

*Conflicts Committee:* As at December 31, 2025 and through to the effective date of the Merger, the Conflicts Committee reviewed certain material transactions between Aspen Holdings and/or its subsidiaries and Apollo or Apollo's non-Aspen affiliates that may present a conflict of interest. As described further herein, in connection with, and shortly following the effective date of, the Merger, the Conflicts Committee was dissolved in February 2026, with certain of its responsibilities transitioning to the Board. Refer to Item 6A for further details.

*Investment Committee:* As at December 31, 2025 and through to the effective date of the Merger, the Investment Committee supported the Board in its oversight responsibilities by reviewing and monitoring the management and performance of the investment function of the Aspen Group, including the review of the investment strategy and annual investment plan and the ongoing monitoring of the Aspen Group's investment managers, including the governance and control framework in place in connection therewith. As described further herein, in connection with, and shortly following the effective date of, the Merger, the Investment Committee was dissolved in February 2026, with certain of its responsibilities transitioning to the Board. Refer to Item 6A for further details.

*Compensation Committee*: As at December 31, 2025 and through to the effective date of the Merger, the Compensation Committee was formally constituted in March 2025 in connection with the IPO and assisted the Board in its oversight duties in respect of the compensation philosophy and strategy of the Aspen Group and its subsidiaries, including, but not limited to, approval of the Group's policies relating to the compensation of its employees, the approval of any issuance of equity or equity-based securities and oversight of the compensation of the Company's Group Chief Executive Officer, key senior employees, executive officers and non-employee directors. As described further herein, in connection with, and shortly following the effective date of, the Merger, the Compensation Committee was dissolved in February 2026, with certain of its responsibilities transitioning to the Board. Refer to Item 6A for further details.

*Nominating and Corporate Governance Committee*: The Nominating and Corporate Governance Committee was formally constituted in March 2025 in connection with the IPO and, as at December 31, 2025, and through to the effective date of the Merger, assisted the Board in its oversight of the evaluation of management and the Board, including the Board Committees, corporate governance matters and practices and make recommendations to the Board in relation thereto, and identify, evaluate and nominate individuals qualified to become Board members and to recommend to the Board director nominees for approval by shareholders at the annual general meetings of shareholders. As described further herein, in connection with, and shortly following the effective date of, the Merger, the Nominating and Corporate Governance Committee was dissolved in February 2026, with certain of its responsibilities transitioning to the Board. Refer to Item 6A for further details.

As from the effective date of the Merger, the responsibilities previously reserved for the Group Executive Committee and its associated Management Committees have been transitioned to the executive officers and other members of senior management of the Company and its affiliates. Refer to Item 6A for further details.

*Management Committees*: As at December 31, 2025 and through the effective date of the Merger, the Group Chief Executive Officer maintained an executive committee (the "Group Executive Committee"), which is the primary executive committee of the Company. It is comprised of global heads of key functions and other key business leads and is responsible for advising the Group Chief Executive Officer and assisting in the execution of his responsibilities to the Board, including with respect to matters relating to the overall strategy and conduct of the Aspen Group's business.

There are various standing committees (the "Executive Management Committees") of the Group Executive Committee, which have oversight of certain business, operational and risk management processes and support the Group Executive Committee in the achievement of its objectives. Membership of the Executive Management Committees includes members of the Group Executive Committee, and the structure of the meetings of the Group Executive Committee contemplates appropriate reporting and feedback from the Executive Management Committees. As of December 31, 2025 and through to the effective time of the Merger, these included:

*Underwriting Committee:* The primary purpose of the Underwriting Committee is to assist the Group Executive Committee through oversight of the design, implementation and operation of the strategic direction of the underwriting function of the Aspen Group, including the review and management of overall underwriting risk and appetite across the Insurance and Reinsurance underwriting segments and all underwriting platforms and legal entities, as well as the coordination of ceded reinsurance placements and approvals.

*Risk and Capital Committee:* The primary purpose of the Risk and Capital Committee is to assist the Group Executive Committee through oversight of the internal control and risk management framework of the Aspen Group. In particular, the Risk and Capital Committee has specific responsibilities in relation to the review of the internal model, monitoring of solvency, capital and liquidity considerations and risk limits for accumulating underwriting and investment exposures, as well as certain compliance matters.

*Claims Committee*: The primary purpose of the Claims Committee is to support the Group Executive Committee in its oversight of the strategy, transformation and management of the global claims function of the Aspen Group, across both Insurance and Reinsurance, including the monitoring of adherence to claims management policies, reporting procedures and standards and the development of an annual strategic plan for the claims function.

*Operating Committee:* The primary purpose of the Operating Committee is to assist the Group Executive Committee through oversight of the operational activities of the Aspen Group, including both in-house and outsourced activities, and the interaction of the operations function with other business function of the Company, including the oversight of the operational risks associated with such functions, to ensure that they are strategically aligned with each other in order to provide coordinated, efficient and cost-effective operational support to the execution of the Aspen Group's strategic objectives.

*Change Board:* The primary purpose of the Change Board is to assist the Group Executive Committee through oversight of the definition, prioritization and initiation of change projects in connection with the change program of Aspen Group and as part of the overall corporate strategy.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Asset and Liability Management Committee:* The primary purpose of the Asset and Liability Management Committee is to oversee the management of the Company's asset and liability management framework, including in relation to interest rate, liquidity, foreign exchange, credit and inflation risks across its assets and liabilities, as well as the development of, and monitoring the adherence to, associated policies and procedures, and review of key assumptions relating to the Company's investment strategy, funding, capital management and treasury plans underpinning the development of the Company's annual business plan as might impact asset and liability outcomes, in collaboration with other business functions.

*Valuation Committee:* The primary purpose of the Valuation Committee is to assist the Group Executive Committee, and in particular, the Group Chief Financial Officer, in its oversight of the valuation framework of the investment portfolio of the Aspen Group, including, but not limited to, hard-to-value and illiquid investments.

*Reserve Committee:* The primary purpose of the Reserve Committee is to support the Group Executive Committee in its oversight of the Aspen Group-level reserves, including consideration of key areas of reserving uncertainty within the Aspen Group-level actuarial central estimate and the management best estimate, which provides the basis for management's recommendation to the Audit Committee and the Board regarding the reserve amounts to be recorded in the financial statements.

The Group Executive Committee previously maintained a Marketing and Communications Committee and a Sustainability Committee, which were dissolved in Q4 2025.

As from the effective date of the Merger, the responsibilities previously reserved for the Group Executive Committee and its associated Management Committees have been transitioned to the executive officers and other members of senior management of the Company and its affiliates. Refer to Item 6A for further details.

In addition to the Group Executive Committee, the Group Chief Executive Officer maintains a Group Disclosure Committee, which assists the Group Chief Executive Officer and the Group Chief Financial Officer, as the Company's certifying officers, in fulfilling their duties for oversight of the accuracy and timeliness of any disclosures made by the Company to ensure that the Company meets its legal and regulatory obligations. This includes the review and approval of disclosures and reports, in accordance with its governance framework, and the maintenance and oversight of a management committee responsible for overseeing compliance with the Sarbanes-Oxley Act, as amended, to the extent applicable.

<u>Risk Management Strategy</u> 

As at December 31, 2025 and up until the effective time of the Merger, Aspen operates an integrated enterprise-wide risk management strategy designed to protect shareholder value and enable sustainable profitable growth while providing a high level of policyholder protection and regulatory compliance. The execution of our integrated risk management strategy is based on:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Establishing and maintaining an internal control and risk management system based on a three lines of defense model, with clear allocation of responsibilities between risk-taking units ("first line"), risk management and oversight functions ("second line") and independent assurance (provided by Internal Audit) ("third line");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• identifying material risks to the achievement of the Aspen Group's objectives including emerging risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Articulating, at Group level, our risk appetite and a consistent set of key risk limits which translate the risk appetite into measurable criteria and provide the primary control for accumulated risk exposures;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cascading risk appetites and key risk limits for material risks to each risk-assuming operating subsidiary;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• measuring, monitoring, managing and reporting risk positions and trends;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Utilizing the Internal Model, subject to an understanding of its limitations, to test strategic and tactical business decisions and to assess compliance with the risk appetite statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Undertaking stress and scenario testing, including reverse stress testing, to help us better understand and develop contingency plans for the potential effects of extreme events or combinations of events on capital adequacy and liquidity.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Risk Appetite Statement.* The Risk Appetite specifies, at a high level, the principles that define how and where Aspen seeks to deploy its financial resources in support of its strategic objectives. The Risk Appetite provides the foundation for strategic planning and decision-making. It sets out boundary conditions and limits for the level of risk we assume, together with a statement of the reward we aim to receive for this level of risk. Our risk appetite statement comprises the following components:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Risk preferences:* Aspen distinguish between "core" and "non-core" risks. Core risks comprise those risks which are inherent in the operation and value creation strategy of our business, including insurance risks in respect of our underwriting operations and market risks in respect of our investment activity.

We actively seek core risks with a view to generating shareholder value but seek to manage the resulting volatility in our earnings and financial condition within the limits defined by our risk appetite. All other risks are classified as non-core. We seek, to the extent we regard as reasonably practicable and economically viable, to avoid or minimize our exposure to non-core risks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Return objective:* Aspen seeks to maximize risk-adjusted returns to meet the financial obligations to shareholders. To meet this objective, Aspen seeks to take risks for which it is adequately compensated and employs active portfolio management to maximize total returns.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Volatility objective:* Aspen focuses on long-term sustainable performance and aims to consistently maximize underwriting profitability while minimizing the inherent volatility of operating results, both in absolute terms and as a percentage of planned earnings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Capital objective:* Aspen's capital risk appetite is based on the objective to maintain a capital position in normal operating conditions that is sufficient to absorb a large loss and allow the Group to continue to meet market and client expectations, satisfy Aspen's rating ambitions and meet regulatory requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Liquidity objective*: Aspen Group's liquidity risk appetite is to meet obligations as they come due, even under stressed conditions.

*Risk Components.* The main types of risks that we face are summarized as follows:

*Insurance risk:* The risk that underwriting results vary from their expected amounts, including the risk that reserves established in respect of prior periods differ significantly from the level of reserves included in the Aspen Group's financial statements.

*Investment/Market risk:* The risk of variations in the valuation of investments due to changes in macroeconomic factors and the general uncertainty related to any investment decision.

*Credit risk:* The risk of diminution in the value of insurance receivables as a result of counter-party default. This principally comprises default and concentration risks relating to amounts receivable from intermediaries, policyholders and reinsurers.

*Liquidity risk:* The risks of failing to maintain sufficient liquid financial resources to meet liabilities as they fall due or to provide collateral as required for commercial or regulatory purposes.

*Operational risk:* The risk of loss resulting from inadequate or failed internal processes, personnel or systems, or from external events. This includes the risk of material misstatement in financial reporting and non-compliance with regulatory requirements.

*Strategic risk*: The risk of adverse impact on shareholder value or income and capital of adverse business decisions, poor execution or failure to respond to market changes.

*Risk Limits Framework.* Aspen's Risk Limit Framework translates the risk appetite and risk tolerance objectives into measurable criteria. Limits provide primary control for Group-wide accumulated risk exposures and provide a mechanism to manage diversification of the Group's risk profile. Additionally, the limit framework establishes the connection to business planning by placing constraints on risk taking decisions.

Limits are established for the most important drivers of risk at the Group level and express the maximum level of allowable exposure per risk driver. At the highest level, risk limits are approved by the Board. Monitoring of the Group position against these limits is included in regular reporting to the Board or one or more of the Board Committees.

*Natural Catastrophe Risk:* Aspen is exposed to an accumulation of losses arising from a natural catastrophe event. The following discussion of the Company's natural catastrophe Probable Maximum Loss (PMLs) information contains forward-looking statements based upon assumptions and expectations concerning the potential effect of future events that are subject to uncertainties. See Item 3D, "*Risk Factors*" for further information. Any of these risk factors could result in actual losses that are materially different from the Company's PML estimates below.

Natural catastrophe risk is a source of significant aggregate exposure for the Company and is managed by setting risk tolerance and limits, as discussed above. Natural catastrophe perils can impact geographic regions of varying size and can have economic repercussions beyond the geographic region directly impacted.

The Company's worldwide estimated net PML exposures (net of retrocession and reinstatement premiums) as at January 1, 2026 and January 1, 2025 were as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|

_______________

(1)&nbsp;&nbsp;&nbsp;&nbsp;Based on total shareholders' equity of $3,625.1 million and $3,371.9 million as at December 31, 2025 and 2024, respectively. The estimates reflect Aspen's view of the modelled maximum losses at the return periods shown which include input from various third-party vendor models and Aspen's proprietary adjustments to these models and planned reinsurance purchases. Catastrophe loss experience may materially differ from the modelled PMLs due to limitations in one or more of the models or uncertainties in the application of policy terms and limits.

(2)&nbsp;&nbsp;&nbsp;&nbsp;Includes all natural catastrophe perils where Aspen has identified an appropriate stochastic model, such as hurricanes, typhoons, wildfire, earthquakes, etc., and includes a loading for non-modelled classes for our most material peril regions.

From January 1, 2025 to January 1, 2026, gross exposure was relatively flat with small increases during the year offset by exposure reductions due to market conditions at January 1, 2026. The increase in net exposure was driven by changes to reinsurance protection. Less ACM was placed for 2026 with fronted participants moving into run-off increasing the reinsurance segment net position. For the insurance segment, the main cat cover was placed with lower attachment but less limit providing more working protection but increasing tail exposure at Group level from 1-in-100 year PMLs upwards. Mid-year resets of the cat bond and ILWs also increased exposure from 1-in-50 year PMLs upwards. An updated view of risk was introduced for European windstorm which had a minor impact slightly increasing tail exposure.

PMLs for key geographic and peril zones are reviewed as part of our annual planning process and are monitored regularly across all portfolios with daily monitoring during key treaty renewal periods. Our underwriting strategy for property catastrophe exposed lines considers a number of underwriting factors and exposure measures including zonal PML limits, standalone and marginal required capital metrics, relative scoring and ranking across and between geographies and perils, terms and conditions and opportunities to deploy capital in other lines of business. Our property strategy is to build and maintain a balanced portfolio of adequately priced catastrophe risks to ensure we optimize our risk adjusted return profile.

**Business Distribution**

Our business is produced principally through brokers and reinsurance intermediaries. The brokerage distribution channel provides us with access to an efficient, global distribution system without the significant time and expense which would be otherwise incurred in creating wholly-owned distribution networks. The brokers and reinsurance intermediaries typically act in the interest of insureds, ceding clients or insurers and are instrumental to our continued relationship with our clients.

(1)&nbsp;&nbsp;&nbsp;&nbsp;The prior periods are re-presented to ensure consistency and replicate the current year breakdown for the addition of new material brokers and/or agents.

**Claims Management** 

The Group's Claims Team are a separate function within Aspen. We have a staff of experienced claims professionals who are structured into three core teams, which are Insurance, Reinsurance and Claims Operations. The Insurance and Reinsurance teams are organized by portfolio with the Claims Operations team working across both teams. The Group Claims team operates under a global structure designed to achieve consistency and efficiencies across all lines of business. We have developed processes and internal business controls for identifying, tracking and settling claims, and authority levels have been established for all individuals involved in the reserving and settlement of claims.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

The key responsibilities of our claims management departments include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• processing, managing and resolving reported insurance or reinsurance claims efficiently and accurately to ensure the proper application of intended coverage, reserving in a timely fashion for the probable ultimate cost of both indemnity and expense and making timely payments in the appropriate amount on those claims for which we are legally obligated to pay;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• selecting appropriate counsel and experts for claims, manage claims-related litigation and regulatory compliance;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• contributing to the underwriting process by collaborating with underwriting teams and senior management in terms of the evolution of policy language and endorsements and providing claim-specific feedback and education regarding claims activity; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• contributing to the analysis and reporting of financial data and forecasts by collaborating with the finance and actuarial functions relating to the drivers of actual claim reserve developments and potential for financial exposures on known claims.

On those facilities and accounts where it is applicable and permitted, external auditing firms in conjunction with a team of in-house claims professionals oversee and regularly audit claims handled under claims delegated authority and outsourcing agreements. The audits may involve a team of in-house claims professionals and that generally applies in relation to the audits of cedants on reinsurance. In addition, any referrals on claims in excess of the authority provided under a claims delegated authority arrangement, whether financial or coverage related, will be managed by the relevant claims handler as required under the terms of those agreements.

Senior management receives a regular report on the status of our reserves and settlement of claims. We recognize that fair interpretation of our reinsurance agreements and insurance policies with our customers, and timely payment of valid claims, are a valuable service to our clients and enhance our reputation.

Under the terms of the LPT with Enstar, Enstar has assumed claims control of the subject business since closing of the transaction and entrance on June 30, 2022 into an administrative services agreement, which sets forth the operational framework for the handling of the subject business. Claims Handling Guidelines were entered into setting out the management and oversight of the subject business. These guidelines ensure Enstar's claims handling aligns to Aspen's claims processes, procedures and philosophy with Enstar operating within Aspen's claims handling systems. Aspen continues to handle certain claims on the subject business under "shared services." The transaction presents certain operational and reputational risks for the Company, including in respect of claims management. For a description of the risks, refer to Item 3, "*Risk Factors — Risks Related to Our Business — Other Operational Risks — We rely on the execution of internal processes to maintain our operations and the operational risks that are inherent to our business, including those resulting from fraud or employee errors or omissions, may result in financial losse*s."

In addition, for further information, please refer to Item 4, "*Information on the Company" – "Legal Proceedings*."

**Reserves** 

Under U.S. Generally Accepted Accounting Principles ("U.S. GAAP") and applicable insurance laws and regulations in the countries where we operate, we are required to establish loss reserves for the estimated unpaid portion of the ultimate liability for losses and loss expenses under the terms of our policies and agreements with our insured and reinsured customers. The process of estimating these reserves involves a considerable degree of judgment and, as of any given date, is inherently uncertain. For a full discussion regarding our loss and loss expenses reserving process, refer to Item 5, "*Operating and Financial Review and Prospects — Critical Accounting Estimates — Reserving Approach*" and, in connection with the risks associated therewith, Item 3D, "*Risk Factors — Risks Related to Our Business — Re)insurance Risks — Our financial condition and operating results may be adversely affected if actual claims exceed our loss reserve*s." The Reserve Committee oversees the development of the Aspen Group-level reserves.

**Investments** 

Our investment strategy is focused on delivering stable investment income and total return through all market cycles while maintaining appropriate portfolio liquidity and credit quality to meet the requirements of our customers, rating agencies and regulators. To enhance investment returns where possible, we tactically adjust the duration of the investment portfolio and asset allocation taking into account the average liability duration of our reinsurance and insurance risks and our views of interest rates, the yield curve, credit spreads and markets for different assets.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

As at December 31, 2025, we maintained an Asset and Liability Management Committee, which reports into the Group Executive Committee. The Group Chief Investment Officer is a voting member of the Asset and Liability Management Committee and provides updates as appropriate to the Group Investment Committee of the Board at its regular meetings, which in turn reports up to the Board. The primary purpose of the Asset and Liability Management Committee is to oversee the management of the Company's asset and liability management framework, including in relation to interest rate, liquidity, foreign exchange, credit and inflation risks across its assets and liabilities, as well as the development of, and monitoring the adherence to, associated policies and procedures, and review of key assumptions relating to the Company's investment strategy underpinning the development of the Company's annual business plan as might impact asset and liability outcomes, in collaboration with other business functions.

The investment guidelines set by each entity's board specify minimum criteria on the overall credit quality and liquidity characteristics of the portfolio, and include limitations on the size of certain holdings and restrictions on purchasing certain types of securities.

For additional information concerning our investments, refer to Item 5, "*Operating and Financial Review and Prosp*ects", Item 18, Notes 4 and 6 of our consolidated financial statements, "*Investments*," and "*Fair Value Measurements*," respectively. For additional information concerning Current Expected Credit Losses ("CECL") on investments, refer to Note 2(c) of our consolidated financial statements, *"Basis of Presentation and Significant Accounting Policies* — *Accounting for Investments, Cash and Cash Equivalen*ts."

**Competition** 

The insurance and reinsurance industries are mature and highly competitive. Competition varies significantly on the basis of product and geography. Insurance and reinsurance companies compete on the basis of many factors, including premium charges, general reputation and perceived financial strength, the terms and conditions of the products offered, ratings assigned by independent rating agencies, speed of claims payments, reputation and experience in the particular risk to be underwritten, quality of service, the jurisdiction where the reinsurer or insurer is licensed or otherwise authorized, capacity and coverages offered and various other factors.

We compete with major U.S., U.K., Bermuda based, European and other international insurers and reinsurers and underwriting syndicates from Lloyd's, some of which have longer operating histories, more capital and/or more favorable financial strength ratings than we do, as well as greater marketing, management and business resources. This also includes new companies that enter the insurance and reinsurance industries. In addition, we compete with capital market participants that create alternative products, such as catastrophe bonds, that are intended to compete with traditional reinsurance products.

Increased competition could result in fewer submissions for our products and services, lower rates charged, slower premium growth and less favorable policy terms and conditions, any of which could adversely impact our growth and profitability. For a further discussion on the risks related to competition in our industry, please refer to Item 3D, "*Risk Factors — Strategic Risks — Competition and consolidation in the (re)insurance industry could reduce our growth and profitabilit*y."

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

**Ratings** 

Ratings by independent agencies are an important factor in establishing the competitive position of (re)insurance companies and are important to our ability to market and sell our products and services. Rating organizations continually review the financial positions of insurers, including us. As of the date of filing, the financial strength ratings of our Operating Subsidiaries were as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Rating Agency** | **Rating** | **Rated Operating Subsidiary** | **Agency**'**s Rating Definition** | **Ranking of Rating** |
| Standard & Poor's Financial Services LLC ("S&P") | A- (Strong - Stable outlook) | Aspen UK, Aspen Bermuda, and AAIC\* | Strong capacity to meet financial commitments but somewhat more susceptible to the adverse effects of changes in circumstances and economic conditions than those in higher-rated categories | The 'A' grouping is the third highest of ten major rating categories. |
| A.M. Best Company, Inc. ("A.M. Best") | A (Excellent) (Stable) | Aspen UK, Aspen Bermuda, Aspen Specialty and AAIC | An excellent ability to meet ongoing insurance obligations | The 'A' grouping is the second highest of seven major rating categories. |
| *\*Note that Aspen Specialty does not maintain its own rating from S&P.* | *\*Note that Aspen Specialty does not maintain its own rating from S&P.* | *\*Note that Aspen Specialty does not maintain its own rating from S&P.* | *\*Note that Aspen Specialty does not maintain its own rating from S&P.* | *\*Note that Aspen Specialty does not maintain its own rating from S&P.* |

---

These ratings reflect the respective opinions of S&P and A.M. Best regarding the ability of the relevant Operating Subsidiary to pay claims and are not evaluations directed to our investors or recommendations to buy, sell or hold our securities. These ratings are subject to periodic review by, and may be revised downward or revoked, at the sole discretion of, S&P and A.M. Best, respectively. Additionally, rating organizations may change their rating methodology, which could have a material impact on our financial strength ratings.

For a discussion of some potential risks relating to the ratings of our Operating Subsidiaries, refer to Item 3D, "*Risk Factors — Strategic Risks — Our Operating Subsidiaries are rated and our Lloyd's business benefits from a rating by one or more of A.M. Best and S&P and a decline in any of these ratings could adversely affect our standing among brokers and customers and cause our premiums and earnings to decrease, or may otherwise result in an adverse effect on our business, financial condition and operating results.*"

**Certain Regulatory Considerations**

***General***

The business of insurance and reinsurance is regulated in most countries, although the degree and type of regulation varies significantly from one jurisdiction to another. Compliance obligations are increasing in most jurisdictions as the focus on insurance regulatory controls has escalated in recent years, with particular emphasis on regulation of solvency, risk management and internal controls. The discussion below summarizes the material laws and regulations applicable to our Operating Subsidiaries and, where relevant, Peregrine. Our companies have met or exceeded the solvency margins and ratios applicable to them under relevant laws and regulations as at December 31, 2025.

***Group Supervision***

As at December 31, 2025 and up until the effective time of the Merger, the Bermuda Monetary Authority (the "BMA") acts as the group supervisor of the Aspen Group and has named Aspen Bermuda as the designated insurer for the Aspen Group. The Insurance Act 1978, as amended (the "Insurance Act") and related group supervision regulations (collectively, the "Group Supervision Regime") set out provisions regarding group supervision and the responsibilities of the designated insurer. The Group Supervision Regime is in addition to the regulation of the Operating Subsidiaries in their local jurisdictions.

As the Aspen Group supervisor, the BMA performs a number of functions including: (i) coordinating the gathering and dissemination of relevant or essential information for going concern or emergency situations, including the dissemination of information which is of importance for the supervisory task of other competent authorities; (ii) carrying out supervisory reviews and assessments of the insurance group; (iii) carrying out assessments of the Aspen Group's compliance with the rules on solvency, risk concentration, intra-group transactions and good governance procedures; (iv) planning and coordinating through regular meetings held at least annually (or by other appropriate means) with other competent authorities, supervisory activities in respect of the insurance group, both as a going concern and in emergency situations; (v) coordinating enforcement actions that may need to be taken against the insurance group or any of its members; and (vi) planning and coordinating meetings of colleges of supervisors in order to facilitate the carrying out of the functions described above. As the designated insurer, Aspen Bermuda is required to facilitate and maintain compliance by the Aspen Group with the Insurance Act and the Group Supervision Regime.

The Insurance Amendment (No.2) Act 2025 (the "Amended Act") came into force on January 7, 2026, which updated the Insurance Act in a number of ways to reflect the BMA's proposals under the consultation paper, 'Proposed Enhancements to the Insurance Group Supervision Framework', which was released on December 4, 2024 (the "Group Supervision Consultation Paper") and the subsequent stakeholder letter dated May 6, 2025, which set out the BMA's responses to the feedback it received from industry stakeholders on the Group Supervision Consultation Paper. The Amended Act has introduced mandatory group supervision by the BMA where an insurance group is either (i) headed by a specified insurer; or (ii) has an ultimate parent company (which is a body corporate) that is incorporated in Bermuda. For this purpose, a 'specified insurer' would be a Class 3A, 3B, 4, C, D, or E insurer (or such other class of insurer designated by the BMA). In addition to mandatory group supervision, the Amended Act introduces the concept of a 'designated insurance holding company'. This does not replace the current roles and responsibilities attributed to the 'designated insurer', but it provides the BMA with the ability to transition group supervision to a non-regulated insurance holding company within the group, should it determine that effective supervision of the insurance group would be better dealt with at the insurance holding company level. Accordingly, the BMA may now designate and register the following as a 'designated insurance holding company': (i) ultimate parent company incorporated in Bermuda; (ii) intermediate holding company incorporated in Bermuda; (iii) specified insurer that heads an insurance group; or (iv) head of an internationally active insurance group. If one of the aforementioned entities is registered as a 'designated insurance holding company', the BMA will be able to extend its powers of supervision and enforcement to such 'designated insurance holding company' as if it were a Bermuda registered insurer, which would allow the BMA to extend certain powers to such entities (including reporting powers and certain powers or intervention). The Amended Act has also introduced certain changes to the "material change" provisions that apply to insurance groups, including the requirement for the designated insurer to seek the BMA's 'no-objection' to an amalgamation, acquisition or merger of any member of an insurance group and other key notification changes.

The lead regulator for the Sompo group holding company system, which includes the Aspen Group, is the Japan Financial Services Agency. As of the effective time of the Merger, the BMA remains the sub-group supervisor for the Aspen Group, and Aspen Bermuda remains the designated insurer for the Aspen Group. The Aspen Group is a wholly-owned subsidiary of Endurance Specialty Insurance Ltd., which is the designated insurer for the Sompo International Holdings Ltd. sub-group, of which the BMA is also the sub-group supervisor. Any reporting obligations with respect to group supervision over the Aspen Group by the BMA are expected to cease after completion of the 2025 year-end filings and BMA sub-group supervision will carry on at the Sompo International Holdings Ltd. level only.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Annual and Quarterly Filings*. On an annual basis, the Aspen Group is required to submit to the BMA: (i) a group statutory financial return; (ii) audited group financial statements including notes to the financial statements, in accordance with GAAP standards ("Group Financial Statements"); and (iii) a group capital and solvency return, which includes the Group BSCR, a risk-based capital adequacy model, and associated schedules, including, amongst others, a Group Solvency Self-Assessment ("GSSA"), a Financial Condition Report (the "FCR") and an opinion of a BMA approved Group Actuary on the economic balance sheet technical provisions. The GSSA is a self-assessment of our risk and solvency requirements that allows the BMA to obtain our view of the capital resources required to achieve our business objectives and to assess our governance, risk management and controls surrounding this process. The Group Financial Statements are published by the BMA on its website and the FCR is published on our public website. In addition, the Aspen Group files quarterly group financial returns with the BMA.

*Group Minimum Solvency Margin and Group Enhanced Capital Requirements.* Aspen Holdings must ensure that the Aspen Group's statutory assets exceed the amount of its statutory liabilities by the aggregate minimum margin of solvency of each qualifying member of the insurance group. A member is a qualifying member if it is subject to solvency requirements in the jurisdiction in which it is registered.

In addition, every insurance group must maintain available statutory capital and surplus in an amount equal to or exceeding its ECR. The ECR is determined either by reference to the BSCR model or an approved internal capital model. The Aspen Group currently relies on the BSCR model to establish its ECR. The BMA also expects insurance groups to operate at or above a group Target Capital Level ("TCL"), which the BMA has set at 120% of the group ECR. The Aspen Group holds capital in excess of its TCL as at December 31, 2025. While an insurance group is not currently required to maintain its statutory capital and surplus at this level, the TCL serves as an early warning tool for the BMA and failure to maintain statutory capital at least equal to the TCL will result in additional reporting requirements and enhanced regulatory monitoring, as well as the submission of a remediation plan to restore capital above the TCL.

***Bermuda Insurance Regulation***

Aspen Bermuda is licensed as a Class 4 insurer and is subject to the Insurance Act, which imposes solvency and liquidity standards as well as auditing and reporting requirements on Bermuda insurers and reinsurers, and it empowers the BMA to supervise, investigate, require information and intervene in the affairs of Bermuda registered insurance companies. There are a number of remedial actions the BMA can take to protect the public interest if it determines that a Bermuda insurer or reinsurer may become insolvent or that a breach of the Insurance Act or of a registration condition has occurred or is about to occur.

In addition to requiring the appointment of a principal representative in Bermuda, the appointment of an independent auditor, the appointment of a loss reserve specialist and the filing of various financial statements and returns, significant provisions of the Insurance Act applicable to Aspen Bermuda include the following:

*Enhanced Capital Requirements.* Similar to the Group requirements, in order to minimize the risk of a shortfall in capital arising from an unexpected adverse deviation, the BMA expects Class 4 insurers such as Aspen Bermuda to maintain a TCL equal to 120% of its ECR. As at December 31, 2025, Aspen Bermuda holds capital in excess of its TCL.

*Minimum Solvency Margin and Minimum Liquidity Ratio*. Aspen Bermuda is also required to comply with a minimum solvency margin ("MSM") and minimum liquidity ratio in respect of its business. The MSM is the greater of: (i) $100,000,000; or (ii) 50% of net written premiums (being gross written premiums less any premiums ceded (not exceeding 25% of gross premiums)) in its current financial year; or (iii) 15% of net losses and loss expense provisions and other insurance reserves; or (iv) 25% of the ECR reported at the end of its relevant year. The minimum liquidity ratio requires that the value of relevant assets not be less than 75% of the amount of relevant liabilities.

Any applicable insurer which at any time fails to meet the MSM requirements must, upon becoming aware of such failure, immediately notify the BMA and, within 14 days thereafter, file a written report with the BMA describing the circumstances that gave rise to the failure and setting out its plan detailing specific actions to be taken and the expected time frame in which the company intends to rectify the failure.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Any applicable insurer which at any time fails to meet the ECR applicable to it must, upon becoming aware of that failure, or of having reason to believe that such a failure has occurred, immediately notify the BMA in writing. In addition, within 14 days of such notification, the insurer must file with the BMA a written report describing the circumstances leading to the failure and a remediation plan, including specific actions to be taken to rectify the failure. Further, within 45 days of becoming aware of that failure, or of having reason to believe that such a failure has occurred, the impacted insurer must furnish the BMA with: (1) unaudited statutory economic balance sheets and unaudited interim financial statements prepared in accordance with GAAP covering such period as the BMA may require, (2) the opinion of a loss reserve specialist, where applicable, (3) a declaration of compliance in respect of those statements, where applicable, (4) a capital and solvency return reflecting an ECR prepared using post-failure data, where applicable and (5) the opinion of an approved actuary, where applicable. An insurer to whom this applies shall not declare or pay any dividends until the failure is rectified.

To enable the BMA to better assess the quality of a regulated insurer's capital resources, applicable insurers are required to disclose the makeup of their capital in accordance with the "3-tiered capital system". Under this system, all of the insurer's capital instruments will be classified as either basic or ancillary capital, which in turn will be classified into one of three tiers based on their "loss absorbency" characteristics. Highest quality capital will be classified as Tier 1 Capital and lesser quality capital will be classified as either Tier 2 Capital or Tier 3 Capital. Under this regime, up to certain specified percentages of Tier 1, Tier 2, and Tier 3 Capital may be used to support the insurer's MSM and ECR.

The characteristics of the capital instruments that must be satisfied to qualify as Tier 1 Capital, Tier 2 Capital, and Tier 3 Capital are set out in the Insurance (Eligible Capital) Rules 2012, as amended. Under these rules, Tier 1 Capital, Tier 2 Capital, and Tier 3 Capital may include capital instruments that do not satisfy the requirement that the instrument be non-redeemable or settled only with the issuance of an instrument of equal or higher quality upon a breach, or if it would cause a breach, in the ECR until January 1, 2027.

While the BMA has previously approved the use of certain instruments for capital purposes, the BMA's consent will need to be obtained if such instruments are to remain eligible for use in satisfying the MSM and the ECR.

The BMA implemented an economic balance sheet ("EBS") framework, which is used as the basis to determine the ECR for all commercial insurers, including Aspen Bermuda. The EBS framework applies prudential filters and other EBS valuation adjustments to an insurer's GAAP balance sheet to produce an economic valuation of the assets and liabilities of the insurer. The Insurance (Prudential Standards) (Class 4 and Class 3B Solvency Requirement) Amendment Rules 2018 provide updates to certain aspects of the EBS framework and increase the ECR over a three-year transition period for general business and a 10-year transition period for long-term business. The Insurance (Prudential Standards) (Class 4 and Class 3B Solvency Requirement) Rules 2018 have been further amended effective March 31, 2024 by the Insurance (Prudential Standards) (Class 4 and Class 3B Solvency requirement) Amendment Rules 2024.

*Restrictions on Dividends, Distributions and Reduction of Capital.* Aspen Bermuda may not declare or pay any dividends during any financial year if it would cause the insurer to fail to meet its relevant solvency margins, enhanced capital requirements or liquidity ratio, and an insurer which fails to meet its relevant margins on the last day of any financial year may not, without the approval of the BMA, declare or pay any dividends during the next financial year. In addition, as a Class 4 insurer, Aspen Bermuda may not in any financial year pay dividends which would exceed 25% of its total statutory capital and surplus, as shown on its statutory balance sheet in relation to the previous financial year, unless it files with the BMA a solvency affidavit at least seven days in advance of payment. Further, Aspen Bermuda must obtain the prior approval of the BMA before reducing by 15% or more its total statutory capital as set out in its previous year's financial statements by filing with the BMA a solvency affidavit.

The Insurance Amendment (No. 2) Act 2018 amended the Insurance Act to provide for the prior payment of unsecured policyholders' liabilities ahead of general unsecured creditors in the event of the liquidation or winding up of an insurer. The amendments provide among other matters that, subject to certain statutorily preferred debts, the insurance debts of an insurer must be paid in priority to all other unsecured debts of the insurer. Insurance debt is defined as a debt to which an insurer is or may become liable pursuant to an insurance contract excluding debts owed to an insurer under an insurance contract where the insurer is the person insured.

In addition, our Bermuda companies, including Aspen Holdings, Aspen Bermuda and ACML, must comply with the provisions of the Companies Act 1981, as amended (the "Companies Act"), which, amongst other matters, regulates the payment of dividends and distributions. A Bermuda company may not declare or pay a dividend or make a distribution out of contributed surplus if there are reasonable grounds for believing that: (i) the company is, or would after the payment be, unable to pay its liabilities as they become due; or (ii) the realizable value of the company's assets would thereby be less than its liabilities.

*Fit and Proper Controllers*

The BMA maintains supervision over controllers (as defined herein) of all Bermuda registered insurers. For these purposes, a controller includes (1) the managing director of the registered insurer or its parent company, (2) the chief executive officer of the registered insurer or of its parent company, (3) a shareholder controller (as defined below) and (4) any person in accordance with those directions or instructions the directors of the registered insurers or its parent company are accustomed to act.

The definition of shareholder controller is set out in the Insurance Act but generally refers to (1) a person who holds 10% or more of the shares carrying rights to vote at a shareholders' meeting of the registered insurer or its parent company, (2) a person who is entitled to exercise 10% or more of the voting power at any shareholders' meeting of such registered insurer or its parent company or (3) a person who is able to exercise significant influence over the management of the registered insurer or its parent company by virtue of its shareholding or its entitlement to exercise, or control the exercise of, the voting power at any shareholders' meeting.

Where the shares of a registered insurer or special purpose insurer, or the shares of its parent company, are traded on a recognized stock exchange (as is the case for Aspen Bermuda and Peregrine), and a person becomes, or ceases to be, a 10%, 20%, 33%, or 50% shareholder controller of the insurer, that shareholder shall, within 45 days, notify the BMA in writing that such shareholder has become, or as a result of a disposition ceased to be, a shareholder controller of any such category. Accordingly, Aspen Bermuda and Peregrine must notify the BMA in writing if any person becomes, or ceases to be, a 10%, 20%, 33%, or 50% shareholder controller within 45 days of the acquisition or disposition.

Similarly where a person becomes, or ceases to be, a 10%, 20%, 33% or 50% shareholder controller of an insurance broker or insurance manager (as is the case for ACML), that shareholder shall, within 14 days, notify the BMA in writing that such shareholder has become, or as a result of a disposition ceased to be, a shareholder controller of any such category. Accordingly, ACML must notify the BMA in writing if any person becomes, or ceases to be, a 10%, 20%, 33%, or 50% shareholder controller within 45 days of the acquisition or disposition.

*Material Change*

All registered insurers, including Aspen Bermuda and Peregrine, are required to give the BMA 30 days' notice of their intention to effect a material change within the meaning of the Insurance Act (including, but not limited to, the amalgamation with or acquisition of another firm or the expansion into a material new line of business), and shall not take any steps to give effect to a material change unless, before the end of the notice period the registered insurer has been notified by the BMA in writing that it has no objection to such change or the period has lapsed without the BMA issuing a notice of objection.

Similarly, each designated insurer is required to give notice to the BMA of any material change in respect of the insurance group of which it is a member. This obligation will apply to Aspen Bermuda, as the designated insurer of the Aspen Group, for which the BMA acts as group supervisor. See "*—Group Supervision*" for more details on the changes to the Group Supervision Regime arising out of the Amended Act.

Further, all registered insurance brokers and insurance managers, including ACML, are required to give the BMA 14 days' notice of their intention to effect a material change within the meaning of the Insurance Act (including, but not limited to, the failure to comply with a condition imposed by the BMA, involvement in any criminal proceedings (including by a shareholder controller or officer), a cyber reporting event (as such term is defined in the Insurance Act) and an amalgamation with, acquisition of, or merger with another firm).

*Peregrine*

*Special Purpose Insurers and Segregated Account Companies*. Peregrine is registered as a special purpose insurer ("SPI") under the Insurance Act and licensed to carry on special purpose business. Special purpose business is defined under the Insurance Act as insurance business under which an insurer fully collateralizes its liabilities to the persons insured, in the forms contemplated by the Insurance Act.

SPIs are required to file electronic statutory financial returns and the BMA has the discretion to modify such insurer's statutory filings requirements under the Insurance Act. Like other (re)insurers, the principal representative of an SPI has a duty to inform the BMA in relation to solvency matters, where applicable.

*Segregated Account Companies.* Peregrine is also registered as a segregated accounts company under the Bermuda Segregated Accounts Companies Act 2000, as amended. As a segregated accounts company, Peregrine is required to segregate the assets and liabilities linked to their respective segregated accounts from the assets and liabilities linked to their other respective segregated accounts and from their general account assets and liabilities. The segregated account representative of a segregated accounts company has the duty to inform the Registrar of Companies in relation to solvency matters and non-compliance, where applicable.

*Economic Substance* 

The Company and certain of our Bermuda-domiciled subsidiaries are also subject to the Economic Substance Act 2018, as amended, and the Economic Substance Regulations 2018, as amended (together the "ESA"). The ESA was enacted to demonstrate Bermuda's commitment to comply with international standards with respect to cooperation for tax purposes and to ensure that Bermuda does not facilitate the use of structures which attract profits, but which do not reflect real economic activity within Bermuda. The ESA provides that a registered entity other than an entity which is resident for tax purposes in certain jurisdictions outside Bermuda ("non-resident entity") that carries on as a business any one or more of the "relevant activities" referred to in the ESA must comply with economic substance requirements. The list of "relevant activities" includes carrying on any one or more of the following activities: banking, insurance, fund management, financing, leasing, headquarters, shipping, distribution and service center, intellectual property and holding entities. Under the ESA, if an entity is engaged in one or more "relevant activities", it is required to maintain a substantial economic presence in Bermuda and to comply with the economic substance requirements set forth in the ESA. An entity will comply with those economic substance requirements if it: (a) is managed and directed in Bermuda; (b) undertakes "core income generating activities" (as may be prescribed under the ESA) in Bermuda in respect of the relevant activity; (c) maintains adequate physical presence in Bermuda; (d) has adequate senior executives, employees or other persons in Bermuda with suitable qualifications; and (e) incurs adequate operating expenditure in Bermuda in relation to the relevant activity undertaken by it.

The ESA requires entities subject to it to make annual filings with the Bermuda Registrar of Companies to demonstrate the economic substance of the entity's activities and business in Bermuda. Companies that are licensed to and carry on insurance as a relevant activity are generally considered to operate in Bermuda with adequate substance, with respect to their insurance business, if they comply with the existing provisions of (a) the Companies Act relating to corporate governance; and (b) the Insurance Act, that are applicable to the economic substance requirements, and the Registrar of Companies will have regard to such companies' compliance with the Insurance Act (in addition to compliance with the Companies Act) in its assessment of compliance with the economic substance requirements. For those Aspen entities subject to the ESA, we expect that the filings will continue to meet the ESA requirements.

*Amendments to Insurance Code of Conduct*

In August 2022, the BMA published various revisions to the Insurance Code of Conduct (the "Insurance Code"), which became effective on September 1, 2022. Aspen Group and Aspen Bermuda have been required to be compliant with the bulk of the amended Insurance Code since September 1, 2023. These revisions are intended to ensure that the Insurance Code remains aligned with international standards and able to address emerging issues. Overall, the amendments aim to improve and enhance the Insurance Code and its application, while at the same time, incorporating various housekeeping changes intended to simplify the document.

The BMA will continue to assess an insurer's compliance with the Insurance Code based on the nature, scale and complexity of the insurer's operations. The BMA does not prescribe the exact manner in which regulated insurers can demonstrate compliance with the Insurance Code and expects individual insurers to use their best judgment when determining what is proportional to their individual circumstances.

*Privacy & Cybersecurity Laws*

PIPA regulates how any organization in Bermuda may use personal information. PIPA became fully operative on January 1, 2025 and applies to all of our Bermuda entities, including the Aspen Group, Aspen Bermuda and Peregrine. From this date, organizations in Bermuda are required to comply with a combination of principle-based and prescriptive rules for the use of personal information. Prescriptive rules for in scope organizations (i.e., those that use personal information, noting "use" is broadly defined) include a requirement to only use personal information where a legal condition applies, a requirement to appoint a data privacy officer, a requirement to provide all individuals with a privacy notice that must contain at a minimum certain required information and requirement to understand and comply with individual rights around access, rectification and erasure.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

In addition, the Insurance Amendment Act of 2020 became operative in August 2020 and requires entities regulated by the BMA to provide notice to the BMA of certain cyber security events. As a result, the BMA's Insurance Sector Operational Cyber Risk Management Code of Conduct ("Cyber Risk Code"), which includes a series of minimum and recommended cyber security standards, became effective on January 1, 2021. The Cyber Risk Code is designed to promote the stable and secure management of information technology systems of regulated entities and requires that all registrants implement their own technology risk programs, determine what their top risks are and develop an appropriate risk response. This requires all registrants to develop a cyber risk policy which is to be delivered pursuant to an operation cyber risk management program and appoint an appropriately qualified member of staff or outsourced resource to the role of Chief Information Security Officer. The role of the Chief Information Security Officer is to deliver the operational cyber risk management program. The Insurance (Group Supervision) Amendment Rules 2022, effective January 1, 2023, enhance the regime by imposing a requirement to report cyber events when an insurance group has knowledge, or reason to believe, that an event resulting in a significant adverse impact to the group's operations, policyholders or clients has occurred within, at most, 72 hours and additionally within 14 days of the notification, the group must furnish the BMA with a report setting out known particulars of the case.

In November 2021, the board of directors of Aspen Bermuda approved a cyber risk policy. The board of directors of Aspen Bermuda must review and approve such policy on at least an annual basis, and reaffirmed its adoption of the cyber risk policy in November 2025. The BMA will assess a registrant's compliance with the Cyber Risk Code in a proportionate manner relative to the nature, scale and complexity of its business. While it is acknowledged that some registrants will use a third party to provide technology services and that they may outsource their information technology resources (for example, to an insurance manager where applicable), when so outsourced, the overall responsibility for the outsourced functions will remain with the registrant's board of directors. Failure to comply with the requirements of the Cyber Risk Code will be taken into account by the BMA in determining whether a registrant is conducting its business in a sound and prudent manner as prescribed by the Insurance Act and may result in the BMA exercising its powers of intervention and investigation.

*Management of Climate Change Risks*

On March 9, 2023, the BMA published the Climate Change Guidance Notes. The Climate Change Guidance Notes apply to the Aspen Group and Aspen Bermuda and outline the BMA's expectations regarding management and reporting of climate change risks. The Climate Change Guidance Notes focus on corporate governance and risk management practices for climate risk in the context of environmental, social and governance risks of insurance business.

Although the Climate Change Guidance Notes focus on how climate change impacts risks that are transferred to insurers (i.e., 'single materiality'), the BMA expects insurers to also specifically consider their own external impact on climate change (i.e., 'double materiality') as it may also revert back and affect in short, mid or long-term their own financial performance, reputation and operations and, by extension, the financial soundness of the sector as a whole.

The Climate Change Guidance Notes seek to take into account the diversity of insurers in the market. While it targets minimum standards the BMA expects insurers to embed into their operations, the BMA's expectations continue to be based on the principle of proportionality. Therefore, the application to the Aspen Group and Aspen Bermuda will be dependent on the nature of our operations and the scale, complexity and risk profile of our insurance business.

Additionally on September 27, 2023, the BMA published a Discussion Paper - Disclosure of Climate Change Risks for Commercial Insurers ("Climate Change Disclosures") outlining the BMA's proposal for insurers to publicly disclose their climate risk exposure, mitigation and monitoring activities, on an annual basis. Aligned to the Task Force on Climate-Related Disclosures ("TCFD") framework, the proposed Climate Change Disclosures focus on four pillars: governance, strategy, risk management and metrics and targets and would require Aspen Group to comply within the financial reporting year ended December 31, 2024 and Aspen Bermuda within the year ended December 31, 2025.

Depending on future developments in this area, the BMA may seek to incorporate elements from the International Sustainability Standards Board's ("ISSB") first two IFRS Sustainability Disclosure Standards, IFRS S1 General Requirements for Disclosure of Sustainability-related Financial Information and IFRS S2 Climate-related Disclosures. The ISSB standards may be sought at the forthcoming consultation paper stage, noting that in 2024, ISSB will succeed the monitoring of companies' progress on climate-related disclosures from TCFD.

***U.K. and E.U. Insurance Regulation***

*General.* The financial services industry in the United Kingdom is currently regulated by the U.K.'s Financial Conduct Authority ("FCA") and the Prudential Regulation Authority ("PRA") (collectively, the "U.K. Regulators"). Aspen UK is authorized by the PRA to effect and carry out (re)insurance contracts in the United Kingdom in classes of general (non-life) business and is regulated by both the PRA with respect to prudential matters and by the FCA with respect to the conduct of its business. AMAL is authorized by the PRA and regulated by the PRA with respect to prudential matters and the FCA with respect to the conduct of its business. AMAL and AUL are also subject to regulation and direction from Lloyd's. For more information see "*—Lloyd's Regulation*" below.

The primary statutory objectives of the PRA in relation to its supervision of insurers and managing agents are: (1) to promote their safety and soundness; and (2) to contribute to the securing of an appropriate degree of protection for policyholders or those who may become policyholders. The PRA also has secondary objectives to facilitate: (i) effective competition in the markets for services provided by PRA-authorized firms, and (ii) subject to aligning with relevant international standards, the international competitiveness of the economy of the U.K. and its growth in the medium to long term. Further, the FCA has a general objective to secure an appropriate degree of protection for consumers, along with the further general objectives to protect and enhance the integrity of the U.K. financial system and to promote effective competition for the benefit of consumers, as well as a similar international competitiveness and growth objective. The U.K. Regulators have extensive powers to intervene in the affairs of insurance businesses and insurance mediation activities that they regulate and to monitor compliance with their objectives. Their enforcement tools include: (i) amending (including by imposing restrictions on) or withdrawing a firm's authorization; (ii) prohibiting, restricting or suspending firms or individuals from carrying on or undertaking regulated activities; and (iii) publicly censuring and warning, fining or requiring compensation from firms and individuals who breach their rules.

U.K. authorized insurers and Lloyd's managing agents must comply with the PRA's requirements (as set out in the PRA Rulebook) and insurers, managing agents and insurance intermediaries must comply with the FCA's requirements (as set out in the FCA Handbook), which include the PRA's Fundamental Rules and the FCA's Principles for Businesses. In particular, under both Fundamental Rule 7 and Principle 11, firms must deal with the U.K. Regulators in an open and cooperative way, and must disclose to the U.K. Regulators anything of which they would reasonably expect notice. Such notifications may include where the firm has reason to believe that it has materially failed to comply with any requirement or if a senior manager is involved in any prohibited activity. U.K. authorized insurers, managing agents and insurance intermediaries must also adhere to a wide range of U.K. insurance legislation. The most notable of such legislation is the FSMA, which includes the requirements for becoming authorized to conduct regulated insurance activities, regulated and prohibited activities of an insurance company and an insurance intermediary, the approval process for the acquisition or disposal of control of insurance companies and insurance intermediaries, rules on financial promotions, transfers of insurance portfolios and market abuse provisions. This is complemented by a range of statutory instruments on certain subjects, for example, the authorization or exemption process. Legislation based on Solvency U.K. is also relevant (as defined and described in more detail under "—Brexit Transition Update" below). In addition, U.K. companies carrying out insurance activities must comply with general legislation, such as the U.K. Companies Act 2006.

The FCA's Insurance: Conduct of Business Sourcebook of the FCA Handbook ("ICOBS") outlines high-level standards that apply to all non-investment insurance product sales such as that of Aspen UK and AMAL from an establishment in the United Kingdom and regulates the standard of day-to-day conduct of business. The overall aim of ICOBS is to ensure that customers within its scope are treated fairly, products and services provide fair price and fair value and to provide customers with clear, fair information when insurance policies are sold.

The FCA's "consumer duty" aims to have a material impact on how financial services companies including insurance companies, managing agents and insurance intermediaries interact with retail customers and set higher standards of care to retail customers over the lifecycle of their products. The rules build on existing product governance and pricing rules and require in-scope companies to define, monitor and evidence how the business models, actions and culture are delivering good customer outcomes in the four areas of products and services, price and value, consumer understanding and consumer support.

Aspen UK, AMAL, and Aspen UK Syndicate Services Limited ("AUKSSL") are subject to the FCA's consumer duty rules. A number of activities were undertaken in order to ensure compliance with the consumer duty rules which included enhancements to governance, management information and reporting, product governance arrangements, delegated underwriting arrangements (including the binding authority agreements entered into with managing general agents) and the appointment of a board-level consumer duty champion for each of the regulated entities.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

In March 2025, the FCA issued feedback statement 25/2 announcing a programme to simplify firms' compliance with the consumer duty. In its September 2025 progress update, the FCA stated that implementation is progressing and that further consultations and publications are expected in 2026, aligned with its 2025/26 priorities, and confirmed that it does not intend to introduce a prescriptive rulebook but will instead rely on targeted consultations and supervisory activity, including multi-firm and sector-specific reviews, to support consistent implementation and improved customer outcomes. Separately, as part of its broader initiative to streamline insurance rules to support growth and innovation, the FCA issued policy statement PS25/21 introducing optional changes, including permitting co-manufacturers to appoint a lead firm for product design and approval obligations and removing the minimum annual product review requirement, effective December 9, 2025. The U.K. general insurance market has already seen significant interventions in relation to specific products and business lines where the FCA believes customers are not receiving fair value and/or that commissions levels received by distributors cannot be justified by the services they provide.

All persons who effectively run the insurance undertakings, managing agents and insurance intermediaries or have other key functions must at all times be fit and proper and notified to and/or approved by the PRA/FCA and Lloyd's (where applicable). The U.K.'s framework for ensuring the standards of such persons is the Senior Managers and Certification Regime ("SM&CR"). The SM&CR consists of three parts: the Senior Managers Regime, the Certification Regime and the Conduct Rules. The application of SM&CR depends on the individual's role and level of seniority in a business.

On July 15, 2025, the FCA issued consultation paper CP25/21 (with a corresponding PRA consultation for dual-regulated firms) proposing targeted "phase 1" changes to streamline the SM&CR while preserving its core accountability objectives, including greater flexibility in approval, certification and reporting processes. The FCA has indicated that a policy statement will follow, with implementation expected in mid-2026, and that further "phase 2" reforms may be developed in coordination with His Majesty's Treasury's ("HM Treasury"), including potential legislative changes.

*Change of Control*

Under FSMA, the prior approval from the PRA and/or FCA is required before any person or entity, together with its associates, acquires "control" of or increases its control over a regulated company, or over the parent undertaking of a regulated company. In relation to Aspen UK and AMAL (which is an authorized insurer and managing agent respectively), in summary, a "controller" is defined for these purposes as a person who holds (either alone or in concert with others) 10% or more of the shares or voting power in the relevant regulated entity or its parent undertaking, or holds significant influence over the management of such regulated entity by virtue of their shareholding or voting power. Thereafter, the prior approval of the PRA and/or FCA is required if any person or entity (or two or more persons acting in concert) proposes to acquire shares or voting power in a regulated entity or the parent undertaking of a regulated entity, such that they cross one of the following shareholding or voting power thresholds: (i) 20% or more but less than 30%; (ii) 30% or more but less than 50%; or (iii) 50% or more. In relation to AUKSSL (which is an authorized insurance intermediary), the test for control is the same, however, there is only one relevant threshold of 20% or more.

Similar to PRA and/or FCA approval, a person seeking to acquire "control" of or increase its control over AMAL is required to obtain Lloyd's prior consent (and the same thresholds noted above apply in this context). Any person seeking to acquire "control" of or increase its control over AUL is required to obtain Lloyd's prior consent (again, the same thresholds noted above apply in this context).

Controllers must notify the PRA and/or FCA, and/or Lloyd's (as applicable) in writing of a reduction or cessation of control before effecting the change, although regulatory approval is not required.

*Brexit Transition Update*

As a result of Brexit concluding on December 31, 2020, Aspen UK lost its ability to underwrite insurance business in all EEA member states via the freedom of services and freedom of establishment rights. However, AMAL continues to be able to access the EEA market through Lloyd's Insurance Company. Lloyd's Insurance Company commenced underwriting all non-life risks from non-U.K. EEA countries from January 1, 2019. Our business written through Lloyd's Insurance Company is 100% reinsured by Syndicate 4711.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Aspen UK has been permitted to continue to collect premiums and pay claims, in all E.U. jurisdictions where it had live risks and/or claims as at Brexit, other than Sweden. In Denmark, Spain and the Netherlands this was under transitional arrangements which expired in 2021, 2022 and 2023, respectively. Transitional arrangements in Ireland expire in 2035. Aspen UK has taken steps to ensure compliance with all post-Brexit local regulatory requirements; this includes action (including novation) to ensure that valid Swedish claims can be settled, and seeking to ensure in jurisdictions with time-limited transitional arrangements that all policies had expired or been novated, and claims where it is the lead insurer settled prior to the expiry of such arrangements. One Spanish claim in litigation continues. Following the March 17, 2023 deadline in the Netherlands, however, we were subsequently made aware that the novation of one coverholder risk had not in fact completed before the deadline; this was reported to DNB (the Dutch regulator). We were informed on July 28, 2023 that the matter had been referred to the DNB's enforcement team, but as of March 10, 2026, the DNB have taken no further action. Cancellation and re-writing of the risk onto Lloyd's Insurance Company with a March 17, 2023 effective date was completed to resolve the situation, and the DNB so informed. For more information, see "*Risk Factors — Risks Related to Our Business — Regulatory Risks — The United Kingdom's withdrawal from the European Union has had, and may continue to have, an adverse impact on our business, results of operations and financial condition*."

U.K. Prudential Regime for Insurers - Reforms Post Brexit. Aspen UK and AUL (by virtue of being a Lloyd's corporate member) are required to meet economic risk-based solvency requirements that were originally set out by the E.U. directive covering the capital adequacy, risk management and regulatory reporting for insurers (the "Solvency II Directive"). Prior to Brexit, the Solvency II Directive, together with European Commission delegated and implementing acts and guidance issued by the European Insurance and Occupational Pensions Authority, had been adopted by the PRA in the United Kingdom and set out classification and eligibility requirements, including the features which capital must display in order to qualify as regulatory capital.

Following the UK's departure from the European Union, the EU (Withdrawal) Act 2018, as amended, transposed all applicable direct EU legislation into domestic U.K. law, ensuring the continuing application of Solvency II under the U.K.'s financial services regulatory regime. In November 2022, HM Treasury set out the U.K. government's final reform package on the Solvency II framework in the U.K. ("Solvency U.K."). Significant changes introduced by these reforms included the reduction in risk margin by 30% for non-life insurers and the removal of branch capital requirements. In June 2023, the Financial Services and Markets Act 2023 ("FSMA 2023") received royal assent. FSMA 2023 provided a framework for the revocation of retained E.U. law in financial services (including Solvency U.K.) and its replacement with corresponding regulators' rules (in the case of Solvency II, mainly in the PRA's Rulebook).

The Insurance and Reinsurance Undertakings (Prudential Requirements) (Risk Margin) Regulations 2023 came into force on December 31, 2023 and modified the current risk margin calculation. The other reforms forming part of Solvency U.K. became effective on December 31, 2024 on the implementation of the PRA's Policy Statement PS15/24 (Review of Solvency II: Restatement of assimilated law). The PRA has stated that these reforms and restatement of rules provide a new regulatory framework for maintaining the safety and soundness of insurance firms and protecting their policyholders, and that the PRA will continue to evolve its prudential regulatory framework for the insurance sector.

***Capital Requirements under the U.K. Prudential Regime***

Aspen UK is required to maintain a minimum margin of solvency (known as "own funds") equivalent to their Solvency Capital Requirements ("SCR") at all times, the calculation of which depends on the type and amount of insurance business written as well as reserve, credit, market and operational risks. To cover similar risks, AUL is required to maintain funding equivalent to its Lloyd's Economic Capital Assessment which is valued by reference to syndicates' SCRs. The financial resources maintained in support of the SCR must be adequate, both as to amount and quality, to ensure that there is no significant risk that an entity's liabilities cannot be met as they fall due. If the PRA with respect to Aspen UK or Lloyd's with respect to Aspen Lloyd's considers that there are insufficient capital resources, it can impose additional requirements in relation to the amount and quality of the resources it considers necessary. Any failure to comply with such requirements introduced by regulators can result in intervention by regulators or the imposition of sanctions, which could have an adverse effect on Aspen UK's and/or Aspen Lloyd's results and financial position.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

The SCR is calculated by an approved internal capital model or by a standard formula prescribed by Solvency U.K. Aspen UK has received approval from the PRA, and AMAL has received approval from Lloyd's, to use an agreed internal model to calculate their respective SCR (the "Internal Model"). Aspen UK and AMAL are required to ensure that the Internal Model operates properly on a continuous basis and that it continues to comply with the "Solvency Capital Requirements - Internal Models" provisions as set out in the PRA Rulebook and Solvency U.K., and, with respect to AMAL, within the Lloyd's regulatory framework, including the principles for doing business at Lloyd's. If Aspen UK fails to comply with these requirements, the PRA may revoke its approval for Aspen UK to use the Internal Model. In addition, failure to adequately capture areas of risk (including as may be identified in the Own Risk and Solvency Assessment ("ORSA")) in the calculation of the SCR may result in the PRA applying a capital add-on to the SCR calculated by the Internal Model. Aspen UK must also maintain the ability to calculate its SCR using the Standard Formula as prescribed by Solvency U.K.

In addition, Aspen UK is required to submit quarterly and annual filings with the PRA including an annual Solvency and Financial Condition Report, which must be posted on Aspen's website. Aspen UK must submit an annual ORSA to the PRA and AMAL must submit an ORSA policy at an agent level to Lloyd's and an ORSA report (covering the syndicate under management) to Lloyd's. The ORSA report is produced annually and provides a summary of all the activity and processes during the preceding year to assess and report on risks and ensure that our overall solvency needs are met at all times, and which will include a forward-looking assessment. It also explains the linkages between business strategy, business planning and capital and risk management processes. Further, Aspen UK and AMAL may need to perform an additional ORSA and submit the corresponding ORSA report to the PRA and/or Lloyd's, following any significant change in its risk profile. In 2021, the PRA granted Aspen UK a waiver for five years absolving it from the requirement to produce certain regulatory returns at the U.K.-sub-group level due to Aspen Bermuda being subject to equivalent group supervision.

From June 30, 2026, the PRA may require a U.K. insurer to provide a Solvent Exit Analysis ("SEA") on request. Subject to limited exceptions, insurers are expected to maintain an SEA setting out how an orderly solvent wind-down would be achieved, with content proportionate to the firm's size, business model and risk profile. The PRA expects the SEA to address key exit actions, risks, triggers, resource and funding needs, governance and communications. Where a solvent exit becomes a realistic prospect, firms are expected to prepare a Solvent Exit Execution Plan and to manage the exit in line with PRA supervisory expectations.

*Material Outsourcing Requirements*

Under U.K. insurance regulation, an outsourcing arrangement is material if it is of such importance that weakness, or failure, of the service provider would cast serious doubt upon the firm's continuing satisfaction of the U.K. Regulators' threshold conditions for authorization and their Fundamental Rules/Principles. The U.K. Regulators require insurers and managing agents to apply adequate governance and controls in respect of material outsourcing agreements.

The most prominent "material outsourcing" rules that apply to Aspen UK and AMAL are set out in the PRA's supervisory statements, "Outsourcing and third party risk management" (SS2/21) and "Operational resilience: Impact tolerances for important business services" (SS1/21). Aspen UK and AMAL are subject to additional related requirements under Solvency U.K. The PRA and the FCA are also progressing proposals on operational incident and material third-party reporting, set out in CP24/28 and CP17/24, alongside the critical third parties oversight regime.

Pursuant to these rules, certain rights pertaining to Aspen UK and AMAL must be included in any material outsourcing agreements, including: (i) the right for Aspen UK and AMAL to receive information from the service provider about the performance of the services; (ii) the right for Aspen UK and AMAL to instruct the service provider in respect of these functions; and (iii) the right for Aspen UK and AMAL, their external auditors and the U.K. Regulators to audit the service provider. See "*Material Contracts*." Aspen UK and AMAL are also required to notify the U.K. Regulators of any new material outsourcing arrangement or material amendments to current material outsourcing agreements and obtain their "non-objection" in relation to them before they can be executed or be materially amended by the parties.

Aspen UK and AMAL must ensure that its board of directors and senior management set appropriate risk management policies, systems and controls in respect of Aspen UK and AMAL's outsourcing and third-party arrangements and must ensure that they are properly carried out. In particular, these individuals should receive clear, consistent, robust and timely management information relating to each service provider's performance which will enable them to effectively oversee these activities and provide challenge in relation to them. If a service provider does not adhere to predetermined performance standards, Aspen UK and AMAL must be able to implement effective remediation procedures or exit strategies.

Aspen UK and AMAL must also ensure that its systems and controls specifically identify and prioritize "important business services," and consider and monitor whether it has dedicated appropriate resources to ensure that it has sufficient operational resilience in the event of any potential material disruption to the services provider (for example, by preparing and maintaining a business continuity or disaster recovery plan covering such circumstances).

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Restrictions on Dividend Payments. The company law of England and Wales prohibits English companies, including Aspen UK, AMAL, AUL, AUKSSL, and other subsidiaries of ours organized under the company law of England and Wales, from declaring dividends to their shareholders unless they have profits available for distribution. The determination of whether a company has profits available for distribution is based on its accumulated realized profits and other distributable reserves less its accumulated realized losses. While the U.K. insurance regulatory rules impose no general restrictions on a general insurer's ability to declare a dividend, the PRA's rules require each authorized insurance company within its jurisdiction to maintain its solvency margin at all times, and any action to declare or pay a dividend in breach of SCR without a PRA waiver may result in the firm's shares being rendered ineligible for Tier 1 treatment. Accordingly, Aspen UK, Aspen Lloyd's (acting through AMAL), and AUL may not pay a dividend if the payment of such dividend would result in their SCR coverage ratio falling below certain levels. In addition, any future changes regarding regulatory requirements, including those described above, may restrict the ability of Aspen UK, AMAL, AUL and AUKSSL to pay dividends in the future.

*Environmental, Social and Governance* 

ESG continues to be an area of focus among our global regulatory authorities including but not limited to the PRA, FCA, Lloyd's and the BMA. The regulators have indicated that ESG will remain a supervisory priority and firms are required to comply with existing and emerging ESG-related requirements. Existing environmental regulations such as the PRA's supervisory statement SS3/19 "Enhancing banks' and insurers' approaches to managing the financial risks from climate change" require Aspen UK and AMAL to: (i) fully embed consideration of climate-related risks into its governance arrangements; incorporate climate-related financial risks into existing risk management practices; (ii) utilize scenario analysis to inform strategy setting, risk assessment and risk identification; and (iii) develop and maintain an appropriate approach to the disclosure of climate-related financial risks. In January 2025, the PRA issued a letter to CEOs concerning its 2025 priorities for insurance supervision, where it indicated that it is planning to consult on an update to SS3/19 to support firms' progress in improving their management of climate-related financial risks. Aspen UK and AMAL are also required to allocate responsibility for managing climate-related risk to a senior manager under SM&CR. Similar climate-related regulations exist for Aspen Group and Aspen Bermuda under the BMA's Climate Change Guidance Notes.

In December 2025, the PRA published policy statement PS25/25, together with supervisory statement SS5/25, which replaces SS3/19. These publications update and clarify the PRA's expectations on climate-related risk management, aligning them with evolving international standards. The updated expectations took effect on publication, and the PRA expects firms to complete an internal gap analysis and develop an implementation plan within six months. In addition, consistent with the PRA's expectations under the SM&CR, responsibility for identifying and managing client-related financial risks should be allocated to an appropriate senior management function and reflected in relevant governance documentation.

In October 2021, Lloyd's published their guidance for managing agents (such as AMAL) on best practices for establishing an ESG strategy and framework. The guidance focuses on integrating ESG within business planning and operations, engagement with the value chain, and policies and conditions. This guidance was supplemented by additional guidance issued by Lloyd's in July 2024.

On November 28, 2023, the FCA published Policy Statement 23/16 which set out its final rules and guidance on the sustainability disclosure requirements and investment labels regime ("the "SDR" regime). As part of this regime, the FCA introduced, among other things, a general 'anti-greenwashing' rule, which is applicable to Aspen UK, AMAL and AUKSSL, to clarify that sustainability-related claims must be clear, fair and not misleading. The general 'anti-greenwashing' rule came into force on May 31, 2024 and the FCA also published guidance (FG 24/3) on the expectations for FCA authorized firms subject to the general 'anti-greenwashing rule' which took effect at the same time. The FCA has stated that it will keep the SDR regime under review and may propose further changes, including in relation to the anti-greenwashing rule.

In March, 2025, the PRA and FCA issued a statement to confirm that, they will not introduce new diversity and inclusion rules and will not revisit the issue until after any related legislation is implemented. In July 2025, the FCA issued consultation paper CP25/18 proposing amendments to the Code of Conduct ("COCON") to address serious non-financial misconduct; these were finalized in December 2025 in policy statement PS25/23. The changes, which align non-bank SM&CR firms more closely with the standards applicable to banks, apply to all FCA-authorised firms (such as Aspen UK, AMAL, and AUKSSL) and individuals subject to COCON and the fit and proper test and will take effect on September 1, 2026 without retrospective application. For further information refer to "*Risk Factors — Risks Related to Our Business— Strategic Risks—Increasing scrutiny and evolving expectations from investors, customers, regulators, policymakers and other stakeholders regarding environmental, social and governance matters may adversely affect our reputation or otherwise adversely impact our business and results of operations.*"

*Brexit and the U.K. GDPR*. Following the United Kingdom's departure from the European Union, commonly referred to as Brexit, the European Union General Data Protection Regulation's (the "E.U. GDPR") data protection obligations continue to apply to the United Kingdom under the so called "U.K. GDPR". The U.K. GDPR exists alongside the U.K. Data Protection Act 2018 (as amended by the U.K. Data (Use and Access) Act 2025) which implements certain derogations in the U.K. GDPR into U.K. law. Under the U.K. GDPR, companies not established in the U.K. but who process personal data (i.e., information which identifies or from which an individual is identifiable) in relation to the offering of goods or services to individuals in the United Kingdom, or to monitor their behavior will be subject to the U.K. GDPR and will be required to appoint a data protection representative in the U.K., provided certain exceptions are not met. Otherwise, the requirements of the U.K. GDPR are currently similar to those of the E.U. GDPR and as such, may lead to similar compliance and operational costs. For information on E.U. GDPR and U.K. GDPR, refer also to "*Risk Factors—Risks Related to Our Business—Other Operational Risks—Compliance with ever evolving national, federal, state, and international laws relating to the handling of information collected from or about individuals involves significant expenditure and resources, and any failure by us or our vendors to comply may result in significant liability, negative publicity and/or an erosion of trust, which could materially adversely affect our business, results of operations and financial condition.*"

In addition, Brexit has implications for transfers of personal data between the UK and the EEA and vice versa. Transfers of personal data from the U.K. to the EEA and vice versa are unrestricted and do not require additional safeguards since the EEA has formally declared the UK's data protection regime as "adequate" and similarly the UK has formally approved the adequacy of the EU. As a result, transfers of personal data from the EEA to the UK, and vice versa, remain unrestricted and do not require any additional safeguards. The duration of the current adequacy decision will expire on December 27, 2031, at which point the European Commission can decide whether to extend the adequacy decision for a further period up to a maximum of another four years.

*E.U./U.K. Cybersecurity and Privacy Laws and Regulations.* The E.U. GDPR and U.K. GDPR (together referred to as the "GDPR") impose comprehensive data privacy compliance obligations in relation to our collection, processing, sharing, disclosure, transfer and other use of personal data including a principal of accountability and the obligation to demonstrate compliance through policies, procedures, training and audits.

In addition, some of the personal data we process in respect to individual customers, policy holders or beneficiaries is special category or sensitive personal data under the GDPR, and subject to additional compliance obligations and to local law derogations. We may be subject to diverging requirements under E.U. member state laws and U.K. law, such as whether consent can be used as the legal basis for processing. As these laws develop, we may need to make operational changes to adapt to these diverging rules, which could increase our costs and adversely affect our business.

Failure to comply with the GDPR could result in penalties for noncompliance. Since we are potentially subject to the supervision of various EU Member State/UK data protection authorities under both the E.U. GDPR and the U.K. GDPR, it is not excluded that we are faced with enforcement action in various EU/UK jurisdictions. Penalties for certain breaches are up to the greater of EUR 20 million/GBP 17.5 million or 4% of our global annual turnover. In addition to fines, a breach of the GDPR may result in regulatory investigations, reputational damage, orders to cease/change our data processing activities, enforcement notices, assessment notices (for a compulsory audit) and/or civil claims (including class actions).

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

The GDPR regulates cross-border transfers of personal data out of the EEA and the U.K. Case law from the Court of Justice of the European Union ("CJEU") states that reliance on the standard contractual clauses – a standard form of contract approved by the European Commission as an adequate personal data transfer mechanism – alone may not necessarily be sufficient in all circumstances, and that transfers must be assessed on a case-by-case basis and supported by a transfer impact assessment followed by the implementation of additional protection measures as appropriate. On October 7, 2022, President Biden signed an Executive Order on 'Enhancing Safeguards for United States Intelligence Activities' which introduced new redress mechanisms and binding safeguards to address the concerns raised by the CJEU in relation to data transfers from the EEA to the United States and which formed the basis of the new E.U.-U.S. Data Privacy Framework ("DPF"), as released on December 13, 2022. The European Commission adopted its adequacy decision in relation to the DPF on July 10, 2023, rendering the DPF effective as an E.U. GDPR transfer mechanism to U.S. entities self-certified under the DPF. On October 12, 2023, the U.K. Extension to the DPF came into effect (as approved by the U.K. Government) as a U.K. GDPR data transfer mechanism to U.S. entities self-certified under the U.K. Extension to the DPF. We currently rely on the E.U. standard contractual clauses and the U.K. Addendum to the EU standard contractual clauses and the U.K. International Data Transfer Agreement, as relevant, to transfer personal data outside the EEA and the U.K. with respect to both intragroup and third party transfers. We expect the existing legal complexity and uncertainty regarding international personal data transfers to continue. In particular, we expect the DPF adequacy decision may still be challenged and international transfers to the United States and to other jurisdictions more generally to continue to be subject to enhanced scrutiny by E.U. regulators. As the regulatory guidance and enforcement landscape in relation to data transfers continue to develop, we could suffer additional costs, complaints and/or regulatory investigations or fines; we may have to stop using certain tools and vendors and make other operational changes; we may have to implement revised standard contractual clauses for existing intragroup, customer and vendor arrangements within required time frames; and/or it could otherwise affect the manner in which we provide our services, and could adversely affect our business, operations and financial condition.

On January 17, 2025, the E.U. Digital Operational Resilience Act ("DORA") entered into effect. DORA applies to "financial entities" including: (i) insurance and reinsurance undertakings, and insurance intermediaries, reinsurance intermediaries and ancillary insurance intermediaries and (ii) ICT third-party service providers to financial entities. DORA imposes regulatory obligations to reinforce the digital operational resilience of entities operating in the financial services industry, and to adequately manage and remediate risks related to the engagement of ICT third-party service providers. In addition to financial entities, DORA only imposes direct regulatory obligations on ICT third-party service providers that are considered "critical" within the meaning of DORA. Non-critical ICT third-party service providers are only indirectly impacted by DORA, by virtue of the mandatory contractual terms that DORA requires financial entities to implement with ICT third-party service providers.

DORA does not provide for minimum or maximum monetary sanctions but empowers E.U. Member State competent authorities to enforce DORA and determine the appropriate sanction on the basis of the factors set out in DORA, including the gravity and duration of the infringement. Sanctions may be administrative or criminal in nature, and DORA also provides that individual members of the management body can be held personally liable for any non-compliance.

*E.U. / U.K. AI Laws and Regulations*. The EU has developed a standalone law to govern the offering and use of AI systems in the EU (the "AI Act") which entered into force on August 1, 2024. The AI Act applies in phases depending on the regulatory requirement in question from February 2025 to August 2027, when all provisions of the AI Act will apply. The AI Act imposes regulatory requirements onto AI system providers, importers, distributors, and deployers, in accordance with the level of risk involved with the AI system ("unacceptable", "high", "limited", and "minimal" risk). General-purpose AI systems have also been made subject to a number of requirements – mostly akin to the requirements that apply to high-risk AI systems under the AI Act.

Non-compliance with the AI Act may be subject to regulatory fines of up to 7% of annual worldwide turnover or €35 million. In parallel, on October 10, 2024, the E.U. adopted the E.U. Product Liability Directive to regulate non-contractual and non-fault based liability for defective products, including digital products and AI facilitating consumer redress for defective AI and digital products.

The U.K. has not, to date, adopted a dedicated AI legislation, instead looking to rely on a principles-based, sector-specific approach to AI regulation.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

We are assessing the scope of application, impact, and risk of these AI and cyber developments in the E.U. and the U.K. on our business and will continue to assess this moving forward. Compliance with these new AI and cyber laws and regulations may require substantial amendments to our procedures and policies and the changes could adversely impact our business by increasing operational and compliance costs or impact business practices. Further, there is a risk that the amended policies and procedures will not be implemented correctly or that individuals within the business will not be fully compliant with the new procedures. If there are breaches of these measures, we could face significant litigation, government investigations, administrative and monetary sanctions as well as reputational damage, which may have a material adverse effect on our operations, financial condition and prospects.

***Branch Regulations***

***General***

Aspen UK and Aspen Bermuda are required to meet local capital requirements and make required local regulatory filings in connection with their respective branch office operations.

***Change of Control***

Similar to the types of regulation noted above with respect to U.S. and U.K. (see "*—U.K. and E.U. Insurance Regulation—Change of Control*" and "*—U.S. Insurance Regulation—Change of Control*"), persons acquiring shares at or above the thresholds noted above may need to notify or obtain approval from regulators of the branches of Aspen Bermuda and/or Aspen UK in Australia, Canada, Singapore and Switzerland, all of which were obtained as part of the Merger.

***Switzerland***

In 2019, Aspen Bermuda established a branch in Zurich, Switzerland to write property and casualty reinsurance and specialty reinsurance with inception dates from January 1, 2020. A branch that writes only reinsurance is not currently subject to supervision under the Insurance Supervision Act (Switzerland) by the Financial Markets Supervisory Authority ("FINMA").

Aspen UK established a property and casualty reinsurance branch in Zurich, Switzerland in 2007. In 2010, Aspen UK established an insurance branch in Zurich, Switzerland, which was regulated by FINMA pursuant to the Insurance Supervision Act (Switzerland). In 2017, Aspen UK discontinued writing insurance business via the insurance branch in Switzerland. In 2020, Aspen UK ceased writing reinsurance via the reinsurance branch in Switzerland, however, FINMA maintains supervision over the Aspen UK branch while the business is in run off.

***Singapore***

In February 2021, Aspen Bermuda received approval from the Monetary Authority of Singapore ("MAS") and established a reinsurance branch in Singapore. The activities of this branch are regulated by the MAS pursuant to The Insurance Act of Singapore. Aspen Bermuda is also regulated by the Accounting and Corporate Regulatory Authority ("ACRA") as a foreign company in Singapore.

Aspen UK has a reinsurance branch in Singapore that is regulated by the MAS and pursuant to The Insurance Act of Singapore and by ACRA as a foreign company in Singapore. Action was taken in 2021 to transition the business currently written through our Aspen UK Singapore branch to the Aspen Bermuda branch in Singapore and it is no longer binding new business.

AMAL set up a subsidiary company, Aspen Singapore Pte. Ltd. ("ASPL"), to access insurance business in Singapore and regulatory approval for ASPL to act as an intermediary was received from MAS in 2015. ASPL was incorporated by ACRA in 2015 as a local company regulated by the Companies Act of Singapore. ASPL went into run-off in September 2021, and was subsequently de-authorized on a voluntary basis with effect from August 31, 2023 in accordance with local regulatory requirements. An application to have ASPL struck off from the public company register was accepted by ACRA in September 2024; ASPL's strike off and dissolution took effect on February 20, 2025.

***Canada***

Aspen UK established a Canadian branch in 2006 whose activities are regulated by the Office of the Superintendent of Financial Institutions ("OSFI"). OSFI is the federal regulatory authority that supervises Canadian and non-Canadian insurance companies operating in Canada pursuant to the Insurance Companies Act (Canada). In addition, the branch is subject to the laws and regulations of each of the provinces and territories in which it is licensed.

***Australia***

Aspen UK established an Australian branch in 2008 whose activities are regulated by the Australian Prudential Regulation Authority ("APRA"). Aspen UK is also registered by the Australian Securities and Investments Commission as a foreign company in Australia under the Corporations Act of Australia 2001. Aspen UK's Australia branch ceased underwriting new or renewal business as at December 31, 2021; Aspen UK filed its formal run-off under APRA regulation on March 25, 2025.

In 2021, the Company formed Aspen Australia Service Company Pty Ltd. ("AASC"), a coverholder which underwrote reinsurance business on behalf of Syndicate 4711 at Lloyd's. AASC ceased writing new or renewal business in AASC effective as at October 31, 2022. AASC's physical office in Australia closed as at March 31, 2023 and the Company is reviewing its strategy for the AASC legal entity.

For additional information on our branches, refer to Item 18,"Note 21—*Commitments and Contingencies*" to our consolidated financial statements.

***Other Regulated Firms***

AUKSSL (previously APJ Services Limited) is authorized and regulated by the FCA. AUKSSL is subject to the Insurance Distribution Directive as adopted into U.K. law. In 2019, HM Treasury has announced its plans to repeal the Insurance Distribution Directive delegated acts and for the requirements of the regulations to be included in the FCA's Handbook. In response, the FCA has issued a consultation paper (CP23/19) on the future regulatory framework for the Insurance Distribution Directive. On December 15, 2023, the final rules that transfer and replace retained E.U. law provisions from the Insurance Distribution Directive were published with an effective date of April 5, 2024. AUKSSL is subject to ongoing monitoring and annual reporting obligations. Accordingly, AUKSSL is required to submit annual reports to the FCA which provide information relating to their controllers and close links, client money and assets, accounts, market data, product sales data, remuneration data and reporting complaints. These reports are also applicable to Aspen UK and AMAL.

***Lloyd's Regulation***

*General.* The operations of Syndicate 4711 are subject to regulation and supervision of the PRA, FCA and the Council of Lloyd's. AMAL is the managing agent for Syndicate 4711 and AUL is the sole corporate underwriting member of Syndicate 4711. The FCA and PRA both regulate insurers, insurance intermediaries and Lloyd's. Lloyd's establishes its own byelaws and regulations, including requirements made under those byelaws that all managing agents and members must comply with.

*Solvency Requirements.* Underwriting capacity of a member of Lloyd's must be supported by providing a deposit (referred to as "Funds at Lloyd's") in the form of cash, securities or letters of credit in an amount determined in accordance with Lloyd's requirements and the Solvency II regime. The amount of such deposit is calculated for each member through the completion of an annual capital adequacy exercise. Under these requirements, it must be demonstrated to Lloyd's that each member has sufficient assets to meet its underwriting liabilities plus a required solvency margin.

*Intervention Powers.* The Council of Lloyd's has wide discretionary powers to regulate members' underwriting at Lloyd's. It may, for instance, change the basis on which syndicate expenses are allocated or vary the Funds at Lloyd's or the investment criteria applicable to the provision of Funds at Lloyd's. Exercising any of these powers might affect the return on an investment of the corporate member in a given underwriting year. Further, the annual business plans of a syndicate are subject to the review and approval by Lloyd's.

Each member of Lloyd's is required to contribute a percentage of that member's underwriting capacity for the relevant year of account to the Lloyd's central fund (the "Central Fund"). If a member of Lloyd's is unable to pay its debts to policyholders, the Council of Lloyd's may exercise its discretion to pay the policyholder from Lloyd's Central Fund. If Lloyd's determines that the Central Fund needs to be increased, it has the power to assess premium levies on current Lloyd's members. In addition, the Council of Lloyd's has discretion to call or assess up to an additional 5% of a member's underwriting capacity in any one year as a Central Fund contribution. Our syndicate capacity for the 2026 underwriting year is £1,300.0 million (2025— £1,300.0 million).

*Lloyd's Insurance Company.* Lloyd's Insurance Company is authorized and regulated by the NBB and regulated by the FSMA. Lloyd's Insurance Company is an authorized insurance company licensed to write non-life risks across the EEA and the United Kingdom and also maintains 19 branches across Europe. Lloyd's Insurance Company is able to underwrite non-life risks, which are then 100% reimbursed by Syndicate 4711. In this way, Syndicate 4711 is able to access the European market.

*Principles for Doing Business at Lloyd's (the "Principles"):* Replacing the Lloyd's Minimum Standards (the previous regime which set out the Lloyd's regulatory requirements for Lloyd's managing agents, the Principles set out the fundamental responsibilities expected of all managing agents, including AMAL and is the basis against which Lloyd's will review and categorize all syndicates and managing agents in terms of their capacity and performance.

***Other Matters***

In 2017, the European Commission opened an investigation into alleged anti-competitive practices in the aviation insurance segment by Aspen UK and other carriers and brokers in the market, but subsequently confirmed in 2021 that it had discontinued its investigation. A similar investigation was opened by the Competition and Consumer Commission of Singapore ("CCCS") in early 2021, and Aspen UK provided initial responses to the CCCS. No specific feedback or request for further information has been received since such time and it appears that the matter has been removed from the Singapore public register on enforcement actions and investigations. In addition, a similar investigation was commenced in 2017 by the Brazilian anti-trust regulator, CADE, and, in 2022, formal allegations of anti-competitive practices in this segment have been alleged against Aspen UK and others in the market, including both brokers and carriers. A formal defense has been lodged by Aspen UK but has been rejected by CADE. Aspen UK has also filed expert evidence. CADE's formal investigation stage concluded in February 2026 with a recommendation to find that the conduct of certain defendants, including Aspen UK, was anti-competitive. The matter is now referred to the CADE Tribunal for formal decision. We continue to engage with local and onshore counsel through the dispute resolution process.

***U.S. Regulation***

*General.* Our U.S. operations are subject to extensive governmental regulation and supervision by the states and jurisdictions in which insurance entities operating in the United States are domiciled, licensed and/or eligible to conduct business. AAIC is licensed to write insurance on an admitted basis in all 50 U.S. states, the District of Columbia, Puerto Rico, Guam and the U.S. Virgin Islands. Aspen Specialty is licensed in North Dakota and is eligible to write surplus lines policies in all 50 U.S. states, Puerto Rico and the District of Columbia. Aspen UK and Syndicate 4711 are not licensed to write insurance on an admitted basis in any state in the United States, but are alien insurers eligible to write surplus lines business in all 50 U.S. states, the District of Columbia, Puerto Rico and other U.S. jurisdictions based on their listing in the Quarterly Listing of Alien Insurers of the International Insurers Department ("IID") of the National Association of Insurance Commissioners ("NAIC"), the organization that works to promote standardization of best practices and assists state insurance regulatory authorities and insurers in the United States by promulgating model insurance laws and regulations for adoption by the states. However, model insurance laws and regulations are only effective when adopted by the states. Pursuant to IID requirements, Aspen UK and Syndicate 4711 have established a U.S. surplus lines trust fund to secure obligations under U.S. surplus lines policies. As of December 31, 2025, Aspen UK's and Syndicate 4711's surplus lines trust fund was $155.2 million (December 31, 2024 — $150.2 million).

The insurance laws and regulations of our U.S. subsidiaries' domiciliary states have the most significant impact on our U.S. operations as well as the lead state regulator of an insurance holding company system. AAIC is domiciled in Texas and Aspen Specialty is domiciled in North Dakota. As of December 31, 2025, and prior to the effective time of the Merger, AAIC and Aspen Specialty were deemed to be part of the Apollo Global Management Group holding company system. Following the completion of the Merger, AAIC and Aspen Specialty ceased to be part of the Apollo Global Management Group holding company system.

Generally, U.S. states regulate insurance holding companies to assure the fairness of inter-affiliate transactions, the propriety of dividends paid to corporate parents and the benefits of any proposed change of control transaction. States also regulate insurer solvency, accounting matters and risk management, as well as a range of operational matters, including authorized lines of business, permitted investments, policy forms and premium rates for admitted companies, maximum single policy risks, adequacy of reserves for losses and unearned premiums and maintenance of in-state deposits for the benefit of policyholders. To monitor compliance, state insurance departments perform periodic market conduct examinations and financial fitness examinations, and require the filing of annual and other reports relating to the financial condition of companies and other matters. Certain U.S. regulatory requirements are highlighted below.

Although the U.S. federal government does not directly regulate the insurance business, federal legislation and administrative policies in several areas can significantly affect the insurance business. The Dodd-Frank Wall Street Reform and Consumer Protection Act (the "Dodd-Frank Act") established the Federal Insurance Office (the "FIO") within the U.S. Department of the Treasury headed by a Director appointed by the Treasury Secretary. While currently not having a general supervisory or regulatory authority over the business of insurance, the Director of the FIO performs various functions with respect to insurance, and any associated actions could ultimately lead to changes in the regulation of insurers and reinsurers in the United States. In addition, AAIC is a certified surety company approved by the U.S. Department of the Treasury and is subject to federal regulations related to Treasury certified sureties.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*State Insurance Holding Company Acts.* All U.S. states have laws regulating insurance holding company systems. These laws require insurance companies, which are formed and chartered in the state (referred to as "domestic insurers"), to register with the state department of insurance (referred to as their "domestic state or regulator") and file information concerning the operations of companies within the holding company system that may materially affect the operations, management or financial condition of the insurers within the system. Insurance holding company regulations principally relate to (i) state insurance approval of the acquisition of domestic insurers, (ii) prior review or approval of certain transactions between the domestic insurer and its affiliates, and (iii) regulation of dividends made by the domestic insurer. All transactions within a holding company system affecting domestic insurers must be determined to be fair and reasonable.

As a result of the NAIC's Solvency Modernization Effort, which dates back to 2008, in 2014, the NAIC adopted the Corporate Governance Annual Disclosure Model Act, which has been enacted by our domestic states of Texas and North Dakota. The model law requires insurers to make an annual confidential filing regarding their corporate governance policies. In addition, the NAIC adopted the Risk Management and Own Risk and Solvency Assessment Model Act ("ORSA"), which also has been adopted by Texas and North Dakota. ORSA requires insurers to maintain a risk management framework and conduct an internal risk and solvency assessment of the insurer's material risks in normal and stressed environments. Many state insurance holding company laws, including those of Texas and North Dakota, have also been amended to require insurers to file an annual confidential enterprise risk report with their lead state regulator, disclosing material risks within the entire holding company system that could pose an enterprise risk to the insurer.

*Change of Control.* The insurance holding company laws and regulations generally provide that no person, corporation, or other entity may acquire control of a domestic insurance company, or a controlling interest in any parent company of such insurance company, without the prior approval of the insurance company's domestic state regulator. A person who acquires, directly or indirectly, 10% or more of the voting interests of an insurance company is presumptively considered to have acquired control of the insurer, although such presumption may be rebutted by a showing that control does not in fact exist. The domestic state regulator may also find that control exists in circumstances in which a person owns or controls less than 10% of voting interest. To obtain approval of any change in control, the proposed acquirer must file an application disclosing, among other information, its background, financial condition, the financial condition of its affiliates, the source and amount of funds by which it will affect the acquisition, the criteria used in determining the nature and amount of consideration to be paid for the acquisition, proposed changes in the management and operations of the insurance company and other related matters.

*State Dividend Limitations.* Under Texas and North Dakota law, respectively, AAIC and Aspen Specialty may only pay dividends out of earned surplus as distinguished from contributed surplus. In addition, under Texas and North Dakota law, an insurance company's policyholder surplus after payment of a dividend must be reasonable in relation to its outstanding liabilities and adequate for its financial needs.

In addition, Texas and North Dakota law generally limit the ability of AAIC or Aspen Specialty to pay dividends above a specified level, without prior regulatory approval. Dividends or distributions in excess of specified level are deemed "extraordinary" and are subject to prior notice to and approval of the applicable state insurance regulator. The maximum amount of ordinary dividend that can be paid without prior regulatory approval is the greater of 10% of a company's surplus as of December 31 of the preceding year, or the amount of net income from the preceding fiscal year.

Aspen U.S. Holdings, Inc. ("Aspen U.S. Holdings") must also meet its own dividend eligibility requirements under Delaware corporate law in order to distribute any dividends received from AAIC. In particular, any dividend paid by Aspen U.S. Holdings must be declared out of surplus or net profits.

*Guaranty Fund Assessments and Residual Market Mechanisms.* Most states require licensed insurance companies to participate in guaranty funds in order to provide funds for payment of losses for insurers which have become insolvent. Assessments are generally between 1% and 2% of annual premium written in the state. Some states also require licensed and admitted insurers to participate in various state residual market mechanisms whose goal is to provide affordability and availability of insurance to those clients who may not otherwise be able to obtain insurance, including, for example catastrophe insurance in high-risk areas. If losses exceed the funds, the pool is available to pay those losses. The pools have the ability to assess insurers to provide additional funds to the pool. The amounts of the assessment for each company are normally based upon the proportion of each insurer's (and in some cases the insurer's and its affiliates') written premium for coverages similar to those provided by the pool, and are frequently uncapped.

*Cybersecurity and Privacy Laws and Regulations.* Federal and state laws and regulations require financial institutions, including insurers, to protect, among other things, the security and confidentiality of personally identifiable information and nonpublic personal information, to notify customers and other individuals about their policies and practices relating to their collection and disclosure of customer information and their practices relating to protecting the security and confidentiality of that information, and to notify regulators and consumers in the event of certain data breaches affecting personal information. Federal and state laws and regulations also regulate the ability of financial institutions to make telemarketing calls and to send unsolicited e-mail or fax messages to consumers and customers. The Gramm-Leach-Bliley Act ("GLBA") requires financial institutions to implement administrative, technical, and physical safeguards to ensure the confidentiality, integrity, security, and proper disposal of nonpublic personal information, as well as limitations on the re-disclosure and re-use of such information.

In 2017, cybersecurity rules took effect for financial institutions, insurers and certain other companies supervised by the New York Department of Financial Services (the "NYDFS Cybersecurity Regulation"), such as AAIC, which is licensed in New York. The NYDFS Cybersecurity Regulation imposes significant regulatory requirements intended to protect the confidentiality, integrity and availability of information systems, and the information stored within, such as requirements regarding governance, incident planning, training, data management, system testing and regulator notification in the event of certain cybersecurity events. On November 1, 2023, NYDFS announced its adoption of the second amendment of the NYDFS Cybersecurity Regulation, which took effect April 29, 2024. The amendments included significant changes, such as (i) expanding the types of cybersecurity events that require timely notification to the NYDFS; and (ii) requiring enhancements to an entity's written policies and procedures related to remote access, vulnerability management, data retention and access privileges. Additionally, the NYDFS previously issued a circular letter in February 2021 announcing its Cyber Insurance Risk Framework which describes best practices for NYDFS-regulated insurers use to manage cyber insurance risk. While the circular letter does not establish new legal standards, it does reflect the NYDFS' interpretation of existing legal and regulatory requirements, and combined with the updated cybersecurity regulations, indicates the increased obligations, expectations and scrutiny on licensed entities' cybersecurity programs. The NYDFS has issued several industry letters detailing agency guidance regarding cybersecurity matters including the use of multi-factor authentication and ransomware prevention, and has been increasingly aggressive in enforcing its cybersecurity regulations. We anticipate that the NYDFS will continue to examine the cybersecurity programs of financial institutions in the future and such examinations may result in additional expenditure of resources and regulatory scrutiny.

In April 2024, the Department of Homeland Security's Cybersecurity and Infrastructure Security Agency published a proposed set of Cyber Incident Reporting for Critical Infrastructure Act Reporting Requirements. The proposal includes broadly applicable reporting requirements for entities in the financial services sector, including a requirement that "substantial" cyber incidents be reported to the agency within 72 hours and ransom payments be reported to the agency within 24 hours. The final rule is expected to be published in May 2026.

In 2017, the NAIC also adopted the Insurance Data Security Model Law (the "Cybersecurity Model Law"). The Cybersecurity Model Law requires insurers, insurance producers and other entities required to be licensed under state insurance laws to comply with certain requirements under state insurance laws, such as developing and maintaining a written information security program, overseeing the data security practices of third-party vendors, and providing notice of certain data breaches. As with all NAIC model laws, this Insurance Data Security Model Law must be adopted by a state before becoming law in such state. The Cybersecurity Model Law closely resembles the NYDFS Cybersecurity Regulation and, as of February 1, 2025, a version of the Cybersecurity Model Law has been adopted by more than half of the U.S. states.

Several states have enacted broad comprehensive data privacy laws that require businesses in scope to disclose information about their privacy practices and give state residents rights to access, delete, and correct their personal information and to opt out of the use of their information for targeted advertising, profiling that results in the provision or denial of decisions including insurance services, and from having their personal information sold to third parties. Most of these laws broadly exempt entities covered by the GLBA or insurers more generally. However, in 2018 California enacted the California Consumer Privacy Act ("CCPA"), which came into effect on January 1, 2020, and broadly regulates the collection, processing and disclosure of the personal information of California residents, imposes limits on the "sale" of personal information and grants California residents certain rights to, among other things, access and delete data about them in certain circumstances. CCPA also established a private right of action, with potentially significant statutory damages, whereby businesses that fail to implement reasonable security measures to protect against breaches of personal information could be liable to affected consumers. The CCPA was expanded substantially on January 1, 2023, when the California Privacy Rights Act of 2020 ("CPRA") amendments to the CCPA became fully operative. The amended CCPA, among other things, gives California residents the ability to limit use of certain sensitive personal information, further restricts the use of cross-contextual advertising, establishes restrictions on the retention of personal information, expands the types of data breaches subject to the CCPA's private right of action, provides for increased penalties for CCPA violations concerning California residents under the age of 16, and establishes a new California Privacy Protection Agency to implement and enforce the new law. While there is currently an exception for personal information that is subject to the GLBA and the California Financial Information Privacy Act, the CCPA may impact certain of our business activities, such as employment, job applicants, and business-to-business settings. Additionally, this exception does not apply to the private cause of action afforded to individuals for information security incidents.

Multiple states have followed California to legislate comprehensive privacy laws with data privacy rights and have enacted similar legislation which will go into effect in the coming years. While these new laws generally include exemptions for GLBA-covered data or GLBA regulated entities or their affiliates, they add layers of complexity to compliance in the U.S. market, and could increase our compliance costs and adversely affect our business.

The use of artificial intelligence ("AI") in the insurance industry is increasingly the subject to state law, regulation, and guidance, as well as certain NAIC undertakings.

For example, Colorado has enacted an insurance AI law that prohibits insurers from using algorithms or predictive models that use external consumer and information data sources in any way that unfairly discriminates and regulations implementing this law for life insurers that require them to establish internal governance and risk management frameworks that address potential discriminatory effects. Similar guidance has been issued by other state insurance regulators, including NYDFS and insurance regulators in California and Connecticut. AI use in the insurance industry may be a focus for state legislators and regulators into the foreseeable future.

U.S. States, including Colorado, Utah and California, have passed comprehensive general AI legislation, and many other states are considering such legislation to govern and manage risk of the development and deployment of AI technologies. For instance, Colorado also recently enacted a comprehensive AI law, Consumer Protections for Interactions with Artificial Intelligence Systems, which went into effect on February 1, 2026, and which applies to "high-risk AI systems" which include AI systems used in insurance and financial or lending services. Unlike certain state privacy laws, this law does not exempt entities subject to the GLBA.

Issues surrounding the use of AI are also a focus for the NAIC. In 2020, the NAIC adopted the Artificial Intelligence (AI) Guiding Principles related to artificial intelligence, its use in the insurance sector, and its impact on consumer protection and privacy, marketplace dynamics and the state-based insurance regulatory framework. In December 2023, the NAIC adopted a model bulletin, The Use of Artificial Intelligence Systems in Insurance, (the "AI Bulletin"), designed to foster uniformity among state insurance regulators regarding expectations for insurance carriers deploying AI. These initiatives have largely come from the NAIC Innovation, Cybersecurity, and Technology (H) Committee and various related working groups focused on the uses of AI in the insurance industry and the development of regulatory frameworks. States have started to adopt the AI Bulletin, which outlines how insurance regulators should govern the development, acquisition and use of AI technologies, as well as the types of information that regulators may request during an investigation or examination of an insurer in regard to AI systems.

We expect that issues related to the use of AI will continue to be an area of focus of the federal government, state legislators and insurance regulators, and the NAIC. We cannot predict what, if any, changes to laws and regulations may be enacted with regard to AI, or the impact any such legislation may have on our business practices, results of operations or financial condition.

Additionally, the NAIC and state insurance regulators have been focused on addressing unfair discrimination in the use of consumer data and technology, and some states have passed laws or introduced legislation targeting unfair discrimination practices. For example, in July 2021, Colorado adopted legislation that restricts the use of consumer data sources, algorithms, and predictive models that unfairly discriminate against an individual based on race, color, national or ethnic origin, religion, sex, sexual orientation, disability or transgender status and would provide the Colorado insurance commissioner with broad rule-making and enforcement authority. Pursuant to such legislation, in September 2023, the Colorado insurance commissioner adopted rules, focused solely on the life insurance industry, establishing expansive requirements for insurers using external consumer data and information sources to establish internal governance and risk management frameworks to ensure that such use does not result in unfairly discriminatory insurance practices. Also, in September 2023, Colorado released a draft artificial intelligence testing regulation for life insurance underwriting to complement the rules that were recently adopted. Several states have also issued guidance regarding the use of big data technology in compliance with anti-discrimination laws. Colorado also recently enacted a comprehensive AI law, Consumer Protections for Interactions with Artificial Intelligence, which will go into effect on February 1, 2026 and will apply to "high-risk AI systems" which include AI systems used in insurance and financial or lending services.

*Operations of Aspen UK and Syndicate 4711.* As stated above, Aspen UK and Syndicate 4711, are eligible to write surplus lines business as alien, non-admitted insurers in all 50 U.S. states, the District of Columbia and other U.S. jurisdictions. Because Aspen UK and Syndicate 4711 are not licensed under the laws of any U.S. state, U.S. solvency regulation tools otherwise applicable to admitted insurers do not generally apply to them. However, Aspen UK and Syndicate 4711 are subject to federal and state incidental regulations in areas such as those pertaining to federal and state reporting related to terrorism coverage and post-disaster emergency orders.

*Credit for Reinsurance.* Aspen UK and Aspen Bermuda also provide reinsurance to U.S. cedants. In general, a U.S. domiciled ceding company that obtains reinsurance from a reinsurer that is licensed, accredited or approved by the jurisdiction in which the ceding company is domiciled is permitted to reflect in its statutory financial statements a credit in an aggregate amount equal to the liability for unearned premiums and loss reserves and loss expense reserves ceded to the reinsurer. Many jurisdictions also permit ceding companies to take credit on their statutory financial statements for reinsurance obtained from unlicensed or non-admitted reinsurers if certain prescribed security arrangements are made. Aspen UK and Aspen Bermuda have obtained approval of a multi-beneficiary trust arrangement that satisfies the credit for reinsurance requirements for their U.S. customers. Generally, the minimum trust fund amount is $20.0 million plus an amount equal to 100% of a reinsurer's U.S. reinsurance liabilities collateralized under this arrangement. Aspen Bermuda has obtained approval to post reduced collateral with respect to obligations owed to cedants domiciled in Florida, New York and North Dakota (i.e., 50% versus 100%).

The Dodd-Frank Act authorized the U.S. Department of the Treasury and the Office of the U.S. Trade Representative to negotiate covered agreements governing certain matters relating to insurance with foreign jurisdictions, including reinsurance collateral, group supervision and exchange of information between supervisory authorities. Such covered agreements could pre-empt state insurance laws. Pursuant to this authority, in September 2017, the U.S. federal authorities and the European Union signed a covered agreement (the "E.U. Covered Agreement") to address, among other things, group supervision and reinsurance collateral requirements and, in anticipation of Brexit, the United States and the United Kingdom signed a covered agreement in December 2018 consistent with the U.S. and E.U. agreement (the "U.K. Covered Agreement" and, together with the E.U. Covered Agreement, the "Covered Agreements"). The United States also released a "Statement of the United States on the Covered Agreement with the European Union" (the "Policy Statement") providing the U.S.'s interpretation of certain provisions in the E.U. Covered Agreement. In terms of reinsurance, both Covered Agreements eliminate collateral and local presence requirements for alien reinsurers that satisfy certain criteria, including being domiciled in a "reciprocal jurisdiction." In 2019 the NAIC adopted additional revisions to its Credit for Reinsurance Model Law and Model Regulation (together, the "2019 Amended Credit for Reinsurance Model Act") to conform to the reinsurance collateral elimination requirements of the Covered Agreements. All states, including Texas and North Dakota, have adopted the 2019 Amended Credit for Reinsurance Model Act. The NAIC has approved Bermuda as a "reciprocal jurisdiction." As of the date of this report, Aspen Bermuda has been approved as a reciprocal jurisdiction reinsurer eligible for zero collateral in all 50 states.

*Developing International Matters and Group Capital.* In November 2019, the International Association of Insurance Supervisors ("IAIS") adopted the Common Framework for the Supervision of Internationally Active Insurance Groups ("ComFrame"). ComFrame is applicable to entities that meet the IAIS's criteria for internationally active insurance groups ("IAIGs") and are designated as such. ComFrame establishes international standards for the designation of a group-wide supervisor for each IAIG and for the imposition of group supervision, group capital requirements, uniform standards for insurer corporate governance, enterprise risk management and other control functions and resolution planning applicable to an IAIG in addition to the current legal entity capital requirements imposed by relevant insurance laws and regulations. The NAIC has also promulgated amendments to the insurance holding company system model law that addresses supervision of IAIGs to allow state insurance regulators in the United States to be designated as group-wide supervisors for U.S.-based IAIGs or acknowledge another regulatory official acting as the group wide supervisor of an IAIG. In November 2019, the IAIS also adopted a revised version of the risk-based global insurance capital standard ("ICS"), which is the group capital component of ComFrame.

In December 2020, the NAIC adopted a group capital calculation ("GCC") tool using an RBC aggregation methodology for all entities within an insurance holding company system group, including non-U.S. entities, and is seeking effective equivalency of such tool to the ICS for U.S.-based IAIGs. The NAIC has also adopted changes to the insurance holding company system model law to require, subject to certain exceptions, the ultimate controlling person of every insurer subject to the holding company registration requirement to file an annual GCC with its lead state regulator. The goal is to provide U.S. regulators with a method to aggregate the available capital and the minimum capital of each entity in a group in a way that applies to all groups regardless of their structure. The Policy Statement with respect to the U.S. participation under the Covered Agreements also provides that the United States expects that the GCC will satisfy the group capital assessment requirement under each of the Covered Agreements. The NAIC has stated that the calculation will be a regulatory tool and will not constitute a requirement or standard. It is not possible to predict what impact any such regulatory tool may have on our business.

**Legal Proceedings** 

Similar to the rest of the insurance and reinsurance industry, we are subject to litigation and arbitration in the ordinary course of our business, which could include matters relating to notable natural catastrophe and man-made loss events, such as in relation to the Russian invasion of Ukraine, the Israel-Hamas conflict and COVID-19. Our subsidiaries are regularly engaged in the investigation, conduct and defense of disputes, or potential disputes, resulting from questions of insurance and reinsurance coverage or claims activities. Pursuant to our insurance and reinsurance arrangements, many of these disputes are resolved by arbitration or other forms of alternative dispute resolution. In some jurisdictions, notably the United States, a failure to deal with such disputes or potential disputes in an appropriate manner could result in an award of "bad faith" punitive damages against our Operating Subsidiaries. In addition, we may be subject to lawsuits and regulatory actions in the normal course of business that do not arise from, or directly relate to, insurance and reinsurance coverage or claims. This category of litigation typically involves, among other things, allegations of underwriting errors or omissions, employment claims or regulatory activity.

While any legal or arbitration proceedings contain an element of uncertainty, we do not believe that the eventual outcome of any specific litigation, arbitration or alternative dispute resolution proceedings to which we are currently a party will have a material adverse effect on the financial condition of our business as a whole.

***LPT***

Cavello Bay commenced proceedings against the Company in the State of Connecticut Superior Court on August 22, 2025. The case was subsequently refiled in the Supreme Court of the State of New York on October 17, 2025. Cavello Bay claims that the Company has breached the LPT in the following respects: (i) by refusing to comply with the Company's contractual obligations to identify and pay or credit premiums collected after October 1, 2021 in respect of the reinsured policies (the "Collected Premium Issue"). Cavello Bay suggests that this claim amounts to a sum in excess of $150 million plus prejudgment interest; (ii) by refusing to comply with the Company's contractual obligations to pay claims with dates of loss after January 1, 2020 under contracts that straddle the period before and after that date (the "Straddle Account Issue"). Cavello Bay claims that the Company is responsible for more than $50 million in paid claims and reserves which are currently allocated to Cavello Bay; and (iii) by refusing to apply proper dates of loss to construction defect claims where the loss occurred partially or entirely after December 31, 2019 (the "Construction Defect Issue"). Cavello Bay claims that the Company's share of Construction Defect claims will exceed $100 million. The Company intends to vigorously defend against these claims and has appointed the law firms Troutman Pepper Locke and DWF to represent it. In line with these firms' recommendations, the Company is: (a) fully defending each of Cavello Bay's claims, and (b) bringing certain counterclaims.

&nbsp;&nbsp;&nbsp;&nbsp;**A. Operating Results** 

Our consolidated financial statements are prepared in accordance with U.S. GAAP. The discussions that follow include tables and commentary relating to our consolidated income statement and our segmental operating results for the twelve months ended December 31, 2025, 2024 and 2023 and should be read in conjunction with our audited consolidated financial statements and related notes contained in this report. This discussion contains forward-looking statements that involve risks and uncertainties and that are not historical facts, including statements about our beliefs and expectations.

*Operating highlights*

&nbsp;&nbsp;&nbsp;&nbsp;• Gross written premiums of $4,673.2 million in 2025 increased by 1.4% from 2024, primarily driven by new business growth and growth with existing cross-class program partnerships. This growth was partially offset by reductions in certain property lines due to rate decreases in the current market and management's decision to not underwrite business which did not meet our profitability expectations.

&nbsp;&nbsp;&nbsp;&nbsp;• Overall underwriting income of $370.8 million (combined ratio of 86.9%) for 2025, including $151.5 million, or 5.3 combined ratio points, of pre-tax catastrophe losses related to significant industry events, including the California wildfires and other weather-related events. Underwriting income of $345.8 million (combined ratio of 87.9%) for 2024, which included $187.3 million, or 6.5 combined ratio points, of pre-tax catastrophe losses, related to significant industry events, including Hurricane Milton, floods in Dubai, Hurricane Helene, the Francis Scott Key Bridge event and other weather-related events.

&nbsp;&nbsp;&nbsp;&nbsp;• Net favorable prior year loss reserve development, on accident years 2020 onwards, of $127.3 million, or 4.5 combined ratio points for 2025, compared with net adverse development for 2024 of $0.6 million, or 0.0 combined ratio points.

&nbsp;&nbsp;&nbsp;&nbsp;• Adjusted underwriting income of $390.5 million (adjusted combined ratio of 86.2%) for 2025 includes an adjustment to remove a loss of $19.7 million for the net impact of the LPT. Adjusted underwriting income represents the performance of our business for accident years 2020 onwards. Adjusted underwriting income of $380.8 million (adjusted combined ratio of 86.8%) for 2024 included an adjustment to remove a loss of $35.0 million for the net impact of the LPT.

&nbsp;&nbsp;&nbsp;&nbsp;*•* Our capital markets business contributed total fee income of $194.4 million in the twelve months ended December 31, 2025, an increase of $25.4 million compared to $169.0 million in 2024. Income from ACM's activities represents ceding commissions and is accounted for as a reduction to acquisition expenses. Third-party capital grew to $2,724.5 million as at December 31, 2025, compared with $2,207.4 million at December 31, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;• Operating return on average equity was 15.9% for 2025 compared with 19.4% in 2024.

*Shareholders' equity* 

Total shareholders' equity increased by $253.2 million, or 7.5%, from $3,371.9 million as at December 31, 2024 to $3,625.1 million as at December 31, 2025, the most significant movements of which were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;• on January 1, 2025, the Company redeemed all of its issued and outstanding 5.950% Fixed-to-Floating Perpetual Non-Cumulative Preference Shares (the "AHL PRC Shares") for an aggregate amount of $275.0 million;

&nbsp;&nbsp;&nbsp;&nbsp;• an increase of $290.3 million in retained earnings due to net income of $340.2 million, partially off-set by $45.5 million in dividends on our Preference Shares and the reclassification of $4.4 million of share issuance costs following the redemption of our AHL PRC Shares;

&nbsp;&nbsp;&nbsp;&nbsp;• other comprehensive income of $191.8 million, which included $136.9 million of net unrealized gains on available for sale investments, a $49.8 million net gain in foreign currency translation on investments classified as available for sale and a $5.1 million net gain in the value of hedged foreign exchange contracts;

&nbsp;&nbsp;&nbsp;&nbsp;• an increase of $41.7 million in additional paid-in capital due to share-based compensation.

As at December 31, 2025, our book value per ordinary share was $31.85, compared with a book value per ordinary share of $26.44 as at December 31, 2024.

As at December 31, 2025, our total shareholders' equity included Preference Shares of $725.0 million less issuance costs of $25.1 million (2024 — $1,000.0 million less issue costs of $29.5 million).

On June 13, 2025, the Company closed its offering of $300.0 million aggregate principal amount of its 5.750% Senior Notes due 2030. The net proceeds from the offering, net of debt issuance costs, were $296.8 million, and the proceeds were used to repay the $300.0 million 2026 Term Loan.

As at December 31, 2025, the Company had approximately $269 million (December 31, 2024 — $379 million) of remaining limit available on our LPT contract, representing 25.9% of our 2019 and prior accident year outstanding reserves. This contract provides protection against deterioration on these accident years, significantly limiting Aspen's exposure to the risk of unfavorable development from these accident years, and strengthens our balance sheet.

On August 27, 2025, the Company entered into a definitive Agreement and Plan of Merger (the "Merger Agreement") under which Aspen was acquired by a wholly-owned indirect subsidiary of Sompo Holdings, Inc. ("Sompo"), a leading global provider of commercial and consumer property and casualty (re)insurance. On February 24, 2026, following the receipt of all required regulatory approvals, the transaction closed. As a result of the transaction, 100% of the Company's Ordinary Shares are indirectly owned by Sompo. The Company's Ordinary Shares were delisted from the New York Stock Exchange and deregistered under the Securities Exchange Act of 1934, as amended. For more information regarding this transaction, refer to Note 1 of our consolidated financial statements, "*History, Organization and Business Combination*" and the "*Explanatory Note*" on page 2 of this report.

---

Overall gross written premiums increased by 1.4% in 2025 compared to 2024. Gross written premiums in our Insurance segment increased by 1.6% in 2025 compared to 2024. The financial and professional line of business saw continued growth with existing cross-class program partnerships, as well as new business growth in our cyber liability portfolio. The other insurance line of business saw increases in gross written premiums due to new business growth. This was partially offset by reductions in casualty and liability insurance due to a strategic pullback in U.S. primary casualty in response to adverse market conditions, coupled with market pressure in the U.K. First party insurance also saw a decline in gross written premiums due to continued softening trading conditions in the U.S. property market.

Gross written premiums in our Reinsurance segment increased by 1.0% in 2025 compared to 2024, largely driven by new business growth in casualty reinsurance as Aspen Re continues to take advantage of favorable market conditions. This was partially offset by reductions in property catastrophe reinsurance and other property reinsurance, due to rate decreases coupled with our continued disciplined approach to underwriting, as we remain selective in writing business that does not meet our risk appetite given current market conditions.

<u>Ceded written premiums</u>

The following table sets forth the ceded written premiums for our two business segments for the twelve months ended December 31, 2025, 2024 and 2023, and the percentage change in ceded written premiums:

| &nbsp;&nbsp;&nbsp;Total | $1837.2 | 10.2% | $1666.7 | 20.3% | $1385.7 |

---

Total ceded written premiums in 2025 increased by $170.5 million, or 10.2%, compared to 2024. Changes in our reinsurance program decreased our retention ratio, which is defined as net written premiums as a percentage of gross written premiums, from 63.8% in 2024 to 60.7% in 2025. Ceded written premiums increased for both our Insurance and Reinsurance segments. This was primarily due to an increase in the level of reinsurance purchased on our financial and professional lines insurance and our casualty reinsurance lines of business.

<u>Net earned premiums</u>

The following table sets forth the net earned premiums for our two business segments for the twelve months ended December 31, 2025, 2024 and 2023, and the percentage change in net earned premiums:

| &nbsp;&nbsp;&nbsp;Total | $2831.9 | (2.0)% | $2889.7 | 10.5% | $2614.5 |

---

Net earned premiums decreased by $57.8 million, or 2.0%, in 2025 compared to 2024 due to an increase of $272.2 million in ceded earned premiums, partially offset by an increase of $214.4 million in gross earned premiums.

<u>Losses and loss adjustment expenses</u>

We have presented the different components of the loss ratios, including adjusting for the impact of the LPT, which includes changes in retroactive reinsurance contracts as we believe that the presentation of adjusted loss ratios reflects the underlying performance of the ongoing portfolio. Additionally, we have also presented current year loss ratios (excluding the impact of catastrophe losses), the impact of catastrophe losses and prior year development for accident years that are not covered by the LPT.

_______________

(1)&nbsp;&nbsp;&nbsp;&nbsp;Adjusted losses and loss adjustment expenses and the adjusted loss ratio are non-GAAP financial measures as defined under SEC rules and regulations. The calculation of the adjusted loss ratio is presented above. Refer to "*Reconciliation of Non-GAAP Financial Measures*" for further details.

The overall loss ratio was 54.6% for the twelve months ended December 31, 2025, a decrease of 4.8 percentage points compared to 59.4% for the twelve months ended December 31, 2024. Losses and loss adjustment expenses decreased from $1,717.8 million in 2024 to $1,546.7 million in 2025. This was mainly due to the following:

*Current accident year losses, excluding the impact of catastrophe losses*. Current accident year losses, excluding the impact of catastrophe losses, contributed $1,502.8 million or 53.1 percentage points for 2025 compared to $1,494.9 million or 51.8 percentage points for 2024. The expense has remained consistent year on year, with the increase in the associated loss ratio predominantly due to a change in business mix following the premium growth in Casualty reinsurance.

*Catastrophe losses.* Catastrophe losses contributed $151.5 million or 5.3 percentage points for the twelve months ended December 31, 2025 compared to $187.3 million or 6.5 percentage points for the twelve months ended December 31, 2024. Catastrophe losses in 2025 include losses associated with the California wildfires and other weather-related events. Catastrophe losses in 2024 were defined as losses associated with Hurricane Milton, floods in Dubai, Hurricane Helene, the Francis Scott Key Bridge event and other weather-related events. Refer to Item 4B, "*Natural Catastrophe Risk*", for details on our PMLs.

*Prior year development on post-LPT years.* For the twelve months ended December 31, 2025, favorable reserve development for accident years 2020 onwards reduced the loss ratio by 4.5 percentage points. For the twelve months ended December 31, 2024, prior year reserve development on post-LPT years contributed minor adverse development which had no impact on the overall loss ratio.

*Adjusted losses and loss adjustment expenses.* The adjusted losses and loss adjustment expenses relate to the post-LPT accident years and exclude the change in deferred gain associated with retroactive reinsurance contracts. Adjusted losses and loss adjustment expenses represents the performance of our business for accident years 2020 onwards, which we believe reflects the underlying underwriting performance of the ongoing portfolio. Refer to Item 18, Note 2 of our consolidated financial statements, "*Basis of Presentation and Significant Accounting Policies*" for additional details of the retroactive reinsurance contracts. The adjusted losses and loss adjustment expenses is the basis on which we report adjusted underwriting income and adjusted combined ratio, as well as the basis in which underwriting income contributes to operating income. Refer to Item 5H, "*Reconciliation of Non-GAAP Financial Measure*s", for further details.

*Impact of the LPT.* The impact of the LPT includes the impact of prior year reserve development on 2019 and prior accident years, net of the change in the deferred gain recognized in relation to retroactive reinsurance contracts which is primarily driven by the LPT, totaling $19.7 million.

<u>Acquisition costs and general and administrative expenses</u>

We monitor the ratio of expenses to net earned premium as a measure of the cost effectiveness of our acquisition costs, and general and administrative expenses. The table below presents the contribution of the acquisition costs, and general and administrative expenses to the net expense ratios for the twelve months ended December 31, 2025, 2024 and 2023.

---

| | | | |
|:---|:---|:---|:---|
| | **Twelve Months Ended December 31,** | **Twelve Months Ended December 31,** | **Twelve Months Ended December 31,** |
| **<u>Ratios Based on Net Earned Premiums</u>** | &nbsp;&nbsp;**2025** | &nbsp;&nbsp;**2024** | **2023** |
| Acquisition cost ratio | 14.9% | 14.5% | 14.5% |
| General and administrative expense ratio | 17.4% | 14.0% | 13.6% |
| &nbsp;&nbsp;&nbsp;Total expense ratio | 32.3% | 28.5% | 28.1% |

---

The acquisition cost ratio remained relatively consistent at 14.9% and 14.5% for 2025 and 2024, respectively, with the movements within the two segments largely offsetting one another. The Insurance segment saw an increase in the acquisition cost ratio due to an increase in delegated underwriting business which attracts a higher acquisition expense, and a reduction in performance related ceding commission. Whereas the Reinsurance segment saw a decrease in the acquisition cost ratio, largely due to higher cessions placed with our capital market partners resulting in an increase in ceding commissions.

The general and administrative expense ratio increased from 14.0% in 2024 to 17.4% in 2025. This increase in general and administrative expenses of $86.1 million, from $405.9 million in 2024 to $492.0 million in 2025, is mainly due to compensation related expenses, which include the impact from inflation and foreign exchange, increased depreciation charge linked to our continued investment in operational excellence enhancements, and higher professional and consulting fees.

<u>Aspen Capital Markets</u>

ACM sources third-party capital and develops reinsurance structures that leverage the Company's underwriting and analytical expertise and earns underwriting, management and performance fees from third-party investors primarily through the placement and management of collateralized quota share sidecar vehicles.

The following table sets forth a summary of fee income and third-party capital with respect to our ACM activity for the twelve months ended December 31, 2025, 2024 and 2023. The increase in fee income was due to the growth achieved in the third-party capital and greater ceded earned premium, including the expansion of our capital markets business into long-tail casualty lines.

(1)&nbsp;&nbsp;&nbsp;&nbsp;Fee income earned through cessions to third-party capital vehicles is recorded through underwriting income/(loss) as a decrease to acquisition costs.

<u>Corporate and other expenses</u>

In 2025, we incurred corporate and other expenses of $102.6 million (2024 — $97.3 million). The increase in corporate and other expenses in 2025 compared to 2024 is mainly due to compensation related expenses, which include the impact from inflation and foreign exchange.

<u>Non-operating expenses</u>

In 2025, we incurred non-operating expenses of $76.8 million, which included expenses in relation to replacement share awards that were granted in substitution for legacy share options previously granted to certain employees upon the successful completion of the IPO of $42.5 million, other IPO related costs of $14.3 million, consultancy and legal fees related to the Company's acquisition by Sompo of $5.0 million, and non-recurring transformation and change activities of $15.0 million.

In 2024, we incurred non-operating expenses of $29.9 million, which included expenses in relation to related party consulting fees paid to Apollo of $5.0 million, and non-recurring transformation and change activities of $24.9 million.

____________

(1) For a discussion on the change in unrealized gains/(losses) on available for sale securities, please refer to "*Other comprehensive income*," below.

(2) Average cash and investments are calculated by taking the average of the opening period and closing period balances for total investments plus cash and cash equivalents.

For the twelve months ended December 31, 2025, net investment income was $326.3 million, an increase of 2.6% from the prior year (2024 — $318.0 million), predominantly due to active rotations of the portfolio to increase yield. The investment portfolio as at December 31, 2025 largely comprised interest income generating fixed income securities. Book yield on the fixed income securities portfolio as at December 31, 2025 was 4.4% compared with 4.2% as at December 31, 2024. Book yield is the yield of the security after adjusting for accretion/amortization of the difference between par value and purchase price.

Total net realized and unrealized investment losses for the twelve months ended December 31, 2025 were $10.9 million (2024 —losses of $49.5 million), which included net unrealized gains of $31.0 million (2024 — gains of $45.3 million). The net realized and unrealized investment losses for the twelve months ended December 31, 2025 were due to realized losses as a result of portfolio rotations, partially offset by unrealized gains on trading assets and unrealized gains due to favorable foreign currency exchange rate movements.

<u>Change in fair value of derivatives</u>

We use derivative instruments to economically hedge foreign currency exposure, in the form of foreign currency forward contracts. We also held an embedded derivative relating to the variable interest expense on the funds withheld arrangement included as part of the Company's LPT contract. The embedded derivative matured during the twelve months ended December 31, 2025.

For the twelve months ended December 31, 2025, the impact of these derivative contracts on net income was a gain of $47.5 million (2024 — loss of $21.1 million), attributable to foreign exchange contracts that had a gain of $43.9 million (2024 — loss of $34.0 million) and a gain within the LPT embedded derivative of $3.6 million (2024 — gain of $12.9 million).

<u>Interest expense</u>

The following table sets forth a summary of the interest expense for the twelve months ended December 31, 2025, 2024 and 2023:

---

| | | | |
|:---|:---|:---|:---|
| | **Twelve Months Ended December 31,** | **Twelve Months Ended December 31,** | **Twelve Months Ended December 31,** |

| Interest and fees on the Long-Term Debt | 18.6 | 21.1 | 15.6 |
| **Interest expense** | $31.7 | $62.1 | $55.2 |

---

The decrease in the interest expense for the twelve months ended December 31, 2025 was primarily driven by the decrease in the interest expense on the funds withheld account related to the LPT contract. The outstanding funds withheld account balance was settled on September 30, 2025.

| Other | (6.0) | 0.2 | (8.2) |
| **Income tax (expense)/benefit** | $(103.9) | $22.0 | $132.1 |

---

The effective tax rate (defined as the tax expense or benefit, divided by the profit or loss before tax), for the twelve months ended December 31, 2025, on profit before tax was 23.4% (2024 — (4.7)%).

The 2024 effective tax rate benefitted from the recognition of a $106.6 million tax benefit from the reversal of brought forward valuation allowances, relating mostly to Net Operating Losses, Deferred Syndicate Losses and Fixed Assets.

On December 27, 2023, the Government of Bermuda enacted the CIT Act, which applies a 15% corporate income tax to certain Bermuda businesses in fiscal years beginning on or after January 1, 2025. The CIT Act includes a provision referred to as the economic transition adjustment, which is intended to provide a fair and equitable transition into the new tax regime and resulted in the recognition of a deferred tax benefit of $201.1 million in 2023.

The effective tax rate is impacted by the relative profitability of the business underwritten in Bermuda, the United Kingdom and the United States, all of which have different income tax rates. Refer to Item 18, Note 11 of our consolidated financial statements, "*Income Taxes*", for further details.

<u>Other comprehensive income</u>

Other comprehensive income, net of taxes, was $191.8 million for the twelve months ended December 31, 2025 (2024 — $10.2 million). Other comprehensive income includes a net unrealized gain on the available for sale investment portfolio of $136.9 million (2024 — net unrealized gain of $29.4 million), which consists of a net unrealized gain of $102.6 million (2024 — $18.5 million net unrealized loss) and a reclassification adjustment of $34.3 million (2024 — $47.9 million) related to the realized loss on the sale of available for sale securities. The net unrealized gain was attributable to the impact of reductions in U.S. Treasury yields on our bond portfolios. The remaining movement is due to an unrealized gain in foreign currency translation on available for sale investments of $49.8 million (2024 — $14.1 million unrealized loss), and a $5.1 million unrealized gain (2024 — $5.1 million unrealized loss) on the hedged derivative contracts.

**Underwriting Results by Business Segment** 

We are organized into two reportable business segments, Insurance and Reinsurance. We have determined our reportable segments by taking into account the manner in which management and ultimately the chief operating decision maker determines operating decisions and assesses operating performance. Income or loss for each of the business segments is measured by underwriting income or loss. Underwriting income is the excess of net earned premiums over the sum of losses and loss adjustment expenses, acquisition costs, and general and administrative expenses. Underwriting income or loss provides a basis for management to evaluate the segment's underwriting performance.

Management measures segment results on the basis of the combined ratio, which is obtained by dividing the sum of the losses and loss adjustment expenses, acquisition costs, and general and administrative expenses by net earned premiums.

*Non-underwriting disclosures.* We provide additional disclosures for corporate and other (non-operating) income and expenses. Corporate and other income and expenses include: corporate and other expenses, non-operating expenses, net investment income, net realized and unrealized investment gains or losses, changes in fair value of derivatives, interest expenses, net realized and unrealized foreign exchange gains or losses, and income taxes. These income and expense items are not allocated to our business segments as they are not directly related to our business segment operations and this approach is consistent with how management measures the performance of its segments. We do not allocate our assets by business segments as we evaluate underwriting results of each segment separately from the results of our investment portfolio.

Segment income or loss for each of our business segments is measured by underwriting income or loss. Refer to Item 18, Note 3 of our consolidated financial statements, "*Segment Reporting*" for information on gross and net premiums written and earned, underwriting income or loss, and combined ratios and reserves for each of our business segments.

---

Gross written premiums increased by 1.6% in 2025 compared to 2024. The increase in financial and professional lines insurance was largely due to continued growth with existing cross-class program partnerships, as well as new business growth in our cyber liability portfolio. The decrease in gross premiums written within casualty and liability insurance was largely attributable to a strategic pullback in U.S. primary casualty in response to adverse market conditions, coupled with market pressure in the U.K. The decrease in first party insurance was predominantly due to continued softening trading conditions in the U.S. property market. The increase in the other insurance lines of business was largely due to new business growth.

<u>Ceded written premiums</u>

Total ceded written premiums for 2025 were $1,163.2 million, an increase of $106.6 million from 2024. This increase was largely driven by an increase in the level of reinsurance purchased protecting our financial and professional lines insurance business line.

<u>Net earned premiums</u>

The table below shows our net earned premiums for each line of business in our Insurance segment for the twelve months ended December 31, 2025, 2024 and 2023, and the percentage change in net earned premiums for each line of business:

---

Net earned premiums in 2025 increased by $39.8 million, or 2.5%, compared to 2024. The increase was due to a $186.5 million increase in gross earned premiums, partially offset by a $146.7 million increase in ceded earned premiums.

<u>Losses and loss adjustment expenses</u>

The loss ratio in 2025 was 53.2%, a decrease of 8.4 percentage points compared to 61.6% in 2024. The main drivers of the change in loss ratio were the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Current accident year loss ratio, excluding catastrophe losses, for 2025 decreased by 1.6 percentage points compared to 2024. The majority of this decrease can be attributed to lower large losses in the financial and professional lines of business compared to prior year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Catastrophe losses increased from $40.5 million in 2024 to $48.3 million in 2025, increasing the loss ratio by 0.4 percentage points. In 2025, the catastrophe losses included $16.1 million from the California wildfires and $32.2 million of other weather-related events, while 2024 included $10.6 million from Hurricane Milton, $7.9 million from Hurricane Helene and $22.0 million of other weather-related events.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Prior year reserve development on post-LPT years totaled favorable development of $98.4 million for the twelve months ended December 31, 2025, compared to adverse development of $0.8 million for the twelve months ended December 31, 2024. This improvement in reserve development resulted in a decrease in the loss ratio of 6.1 percentage points. The favorable prior year reserve development in 2025 was largely due to better-than-expected loss emergence in our first party insurance and specialty insurance lines of business. The adverse prior year reserve development in 2024 was largely due to strengthening on the casualty and liability insurance, financial and professional lines insurance, and other insurance lines of business. This was partially offset by favorable development on our first party insurance line of business, due to better-than-expected loss emergence, and COVID recoveries within our specialty insurance line of business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Impact of the LPT included a favorable movement of $7.0 million or 0.5 percentage points in the current period compared with an unfavorable movement of $10.4 million in the twelve months ended December 31, 2024. This reflects reserve development in the 2019 and prior accident years covered by the LPT, net of the movement in the deferred gain on retroactive contracts allocated to the Insurance segment.

<u>Acquisition costs</u>

Net acquisition costs were $243.4 million in 2025, equivalent to 15.0% of net earned premiums, versus $193.2 million or 12.2% of net earned premiums in 2024. The increase in the acquisition cost ratio in 2025 was mainly due to an increase in delegated underwriting business which attracts a higher acquisition expense and a reduction in performance related ceding commission.

<u>General and administrative expenses</u>

General and administrative expenses increased by $39.1 million, from $264.2 million in 2024 to $303.3 million in 2025. The general and administrative expense ratio was 18.7% in 2025, an increase of 2.0 percentage points from 2024. This increase was mainly due to compensation related expenses, which include the impact from inflation and foreign exchange, increased depreciation charge linked to our continued investment in operational excellence enhancements, and higher professional and consulting fees.

Gross written premiums increased by 1.0% in 2025 compared to 2024. The increase in casualty reinsurance is driven by new business growth as Aspen Re continues to take advantage of favorable market conditions. The decreases in property catastrophe reinsurance and other property reinsurance were predominantly due to rate decreases, coupled with our continued disciplined approach to underwriting, as we remain selective in writing business that does not meet our risk appetite given the current market conditions.

<u>Ceded written premiums</u>

Total ceded written premiums for 2025 were $674.0 million, an increase of $63.9 million compared to 2024. This increase was largely driven by an increase in the level of reinsurance purchased protecting our casualty reinsurance business line.

<u>Net earned premiums</u>

---

Net earned premiums in 2025 decreased by $97.6 million, or 7.5%, compared to 2024. The decrease was due to a $125.5 million increase in ceded earned premiums, partially offset by a $27.9 million increase in gross earned premiums.

<u>Losses and loss adjustment expenses</u>

The loss ratio in 2025 was 56.5%, a decrease of 0.3 percentage points compared to 56.8% in 2024. The main drivers of the change in loss ratio were the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Current accident year loss ratio, excluding catastrophe losses, increased by 4.6 percentage points from 43.6% in 2024 to 48.2% in 2025. The increase in the ratio can be predominantly attributed to a change in business mix following the premium growth in Casualty reinsurance coupled with favorable prior year premium adjustments in 2024 and adverse prior year premium adjustments in 2025 impacting net earned premiums, driving the increase in the current accident year loss ratio, excluding catastrophe losses.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Catastrophe losses decreased from $146.8 million in 2024 to $103.2 million in 2025, decreasing the loss ratio by 2.7 percentage points. In 2025, catastrophe losses included $47.4 million from the California wildfires and $55.8 million of other weather-related events. In 2024, catastrophe losses included $26.2 million from Hurricane Milton, $22.5 million from floods in Dubai, $14.7 million from the Francis Scott Key Bridge event, $11.1 million from Hurricane Helene, and $72.3 million of other weather-related events.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Prior year reserve development on post-LPT years totaled favorable development of $28.9 million in 2025 compared with favorable development of $0.2 million for the twelve months ended December 31, 2024. This improvement in prior year reserve development resulted in a decrease in the loss ratio of 2.4 percentage points compared to prior year. The favorable prior year reserve development in 2025 was largely due to reserve releases in the property catastrophe reinsurance and other property reinsurance lines of business as a result of better-than-expected loss emergence. This was partially offset by reserve strengthening in the casualty reinsurance and specialty reinsurance lines of business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Impact of the LPT amounts to an unfavorable movement of $26.7 million, or 2.2 percentage points, in the current period compared with an unfavorable movement of $24.6 million in the twelve months ended December 31, 2024. This reflects reserve development in the 2019 and prior accident years covered by the LPT, net of the movement in the deferred gain on retroactive contracts allocated to the Reinsurance segment.

<u>Acquisition costs</u>

Net acquisition costs were $179.0 million for the twelve months ended December 31, 2025, equivalent to 14.8% of net earned premiums (2024 — $227.0 million or 17.4% of net earned premiums). The decrease in the acquisition cost ratio was primarily driven by higher cessions placed with our capital market partners resulting in an increase in ceding commissions.

<u>General and administrative expenses</u>

General and administrative expenses increased by $47.0 million, from $141.7 million in 2024 to $188.7 million in 2025. The general and administrative expense ratio was 15.6% in 2025, an increase of 4.7 percentage points from 2024. The increase in general and administrative expenses is largely driven by performance based compensation, a higher expense base resulting from inflation and foreign exchange, increased depreciation charge linked to our continued investment in operational excellence enhancements, and higher professional and consulting fees.

**Balance Sheet** 

***Total cash and investments***

As at December 31, 2025 and 2024, total cash and investments, including accrued interest receivable, were $8.3 billion and $7.7 billion, respectively. Total cash and investments increased mainly due to cash generated from operating activities of $439.0 million, and net realized and unrealized investment gains of $160.1 million. This was partially offset by the payment of preference share dividends of $45.5 million.

Our investment strategy is focused on delivering stable investment income and total investment returns through all market cycles while maintaining appropriate portfolio liquidity and credit quality to meet the requirements of our customers, rating agencies and regulators. We also consider how our investments should match the liability characteristics in terms of duration and foreign currencies.

As of December 31, 2025, a significant majority of funds available for investment were deployed in a diversified portfolio of high quality, investment grade securities, including U.S. government, corporate and U.S. agency mortgage-backed securities. As part of our strategic asset allocation, we also invest a portion of our portfolio in investments such as unrated private fixed and floating rate investments, and other investments not categorized as fixed income. These securities generally pay a higher rate of interest or return and may have a higher degree of credit or default risk, or less liquidity.

The duration of total fixed income securities (the aggregate of available for sale and trading) as at December 31, 2025 was 3.4 years compared to 2.9 years as at December 31, 2024. In addition, as at December 31, 2025, the average credit rating of these fixed income securities was " AA- ," with 85.1% being rated "A-" or higher. As at December 31, 2024, the average credit rating of our fixed income securities portfolio was "AA-," with 85.7% being rated "A-" or higher. The average credit rating is calculated using the Bloomberg Barclays Index credit quality methodology.

As at December 31, 2025, the Company had a 3.4% allocation to investment funds and a 0.6% allocation to middle market loans and other private debt ("MMLs") and commercial mortgage loans ("CMLs"), representing in total 4.0% of our portfolio. As at December 31, 2024, the Company had a 3.5% allocation to investment funds and a 1.8% allocation to MMLs and CMLs representing in total 5.3% of our portfolio.

Cumulative unrealized losses in the available for sale investment portfolio, net of taxes, were $61.3 million as at December 31, 2025, a decrease of $136.9 million from the net $198.2 million unrealized losses as at December 31, 2024. During 2025, the unrealized loss position was reduced largely as a result of reductions in U.S. Treasury yields.

As at December 31, 2025, the aggregate fair value of the investment funds was $279.6 million (December 31, 2024 — $267.2 million). For further information regarding these investments, refer to Item 18, Note 4 of our consolidated financial statements, "*Investments*".

As at December 31, 2025 , the Company had $8.1 million of investments in equity securities as part of the Company's strategic asset allocation (December 31, 2024 — $Nil).

***Valuation of Investments***

*Fair Value Measurements.* Our estimates of fair value for financial assets and liabilities are based on the framework established in the fair value accounting guidance included in ASC Topic 820, *Fair Value Measurements and Disclosures*. For a description of the framework, refer to Item 18, Note 6 of our consolidated financial statements, "*Fair Value Measurements*."

*Valuation of Investments, Equity Method.* The value of our equity method investments is based on our share of the capital position of the equity method investees, which includes income and expenses reported in quarterly management accounts. The equity method investees are subject to annual audits of their financial statements. We periodically review the management accounts of the equity method investees and evaluate the reasonableness of the carrying value of our equity method investments.

*Valuation of Other Investments.* The Company's other investments represent our investments in investment funds. Adjustments to the fair values are made based on the net asset value of the investments. The net valuation criteria established by the manager of such investments are established in accordance with the governing documents and the asset manager's valuation guidelines, which include: the discounted cash flow method and the performance multiple approach, which uses a multiple derived from market data of comparable companies or assets to produce operating performance metrics. Alternative valuation methodologies may be employed for investments with unusual characteristics.

*Valuation of Privately-held Investments.* Privately-held investments are initially valued at cost or transaction value which approximates fair value. In subsequent measurement periods, the fair values of these securities are largely determined using discounted cash flow models. Investment valuations are performed by an independent valuation vendor which includes an assessment of the reasonableness of the discount rate being used. These models include inputs that are specific to each investment. The inputs used in the fair value measurements include dividend or interest rates and appropriate discount rates. The selection of an appropriate discount rate is judgmental and is the most significant unobservable input used in the valuation of these securities. A significant increase (decrease) in this input in isolation could result in significantly lower (higher) fair value measurements for privately-held investments. In order to assess the reasonableness of the inputs in the discounted cash flow models, the Company maintains an understanding of current market conditions and issuer specific information that may impact future cash flows.

*Credit Losses on Available for Sale Debt Securities*. Credit losses are recognized through an allowance account for available for sale debt securities, thereby permitting reversals of previously recognized credit losses through net income in the period they occur. Write-offs (of any previously recognized allowance for credit losses) are recorded when amounts are deemed uncollectible, or Aspen intends to sell (or more likely than not will be required to sell) the debt security before recovery of the amortized cost basis. The amortized cost basis will be written down to the debt securities fair value through earnings. Credit losses are limited to the difference between the debt securities amortized cost basis and fair value. Any decline in the debt securities fair value below the amortized cost basis that is not a result of a credit loss is recorded through other comprehensive income, net of applicable taxes. The allowance for credit losses of a security may be increased or reversed upon a change in credit position with the change reflected in net income.

The credit loss models employ a discounted cash flow approach to evaluate whether a credit loss exists at the individual security level and are reviewed at each reporting period. This analysis excludes investments in U.S. Government/Agency bonds and U.S. Government Agency mortgage-backed securities due to being of 'high credit quality' based on the absence of risk. For any available for sale debt securities that were initially purchased with credit deterioration, the amortized cost basis shall be considered to be the purchase price, plus any allowance for credit losses. Estimated credit losses shall be discounted at the rate that equates the present value of the purchaser's estimate of the security's future cash flows with the purchase price of the asset. As at December 31, 2025 we recognized a credit loss provision of $0.3 million (2024 —$1.0 million), realizing a gain of $0.7 million within the twelve months ended December 31, 2025.

For further discussion, refer to Item 18, Note 2(c) of our consolidated financial statements, "*Basis of Presentation and Significant Accounting Policies — Accounting for Investments, Cash and Cash Equivalents*."

***Reserves for Losses and Loss Adjustment Expenses***

Provision is made at the end of each year for the estimated ultimate cost of claims incurred but not settled at the balance sheet date, including the cost of IBNR claims and development of existing reported claims. The estimated cost of claims includes expenses to be incurred in settling claims and a deduction for the expected value of salvage and other recoveries. Estimated amounts recoverable from reinsurers on unpaid losses and loss adjustment expenses are calculated to arrive at a net claims reserve.

*Reserves by segment.* As at December 31, 2025, we had total net loss and loss adjustment expense reserves of $4,443.1 million (December 31, 2024 — $3,950.6 million). This amount represented our best estimate of the ultimate liability for payment of losses and loss adjustment expenses. Of the total gross reserves for unpaid losses of $8,725.0 million at December 31, 2025, a total of $5,895.1 million, or 67.6%, represented IBNR claims (December 31, 2024 — $5,247.7 million and 64.6%, respectively). The following tables analyze gross and net loss and loss adjustment expense reserves by business segment as at December 31, 2025 and 2024, respectively:

*For the twelve months ended December 31, 2025*. The analysis of the development by each segment is as follows:

*Insurance.* Net favorable reserve development of $105.4 million in 2025, due to favorable prior year development on post-LPT accident years of $98.4 million and the favorable movement of $7.0 million due to the impact of the LPT.

*Reinsurance.* Net favorable reserve development of $2.2 million in 2025, due to favorable development on post-LPT accident years of $28.9 million, partially offset by the unfavorable impact of the LPT of $26.7 million.

*For the twelve months ended December 31, 2024*. The analysis of the development by each segment is as follows:

*Insurance.* Net adverse reserve development of $11.2 million in 2024, due to adverse prior year development on post-LPT accident years of $0.8 million and the unfavorable movement of $10.4 million due to the impact of the LPT.

*Reinsurance.* Net adverse reserve development of $24.4 million in 2024, due to the unfavorable impact of the LPT of $24.6 million, partially offset by favorable development on post-LPT accident years of $0.2 million.

We did not make any significant changes to the methodologies used in our reserving process between 2024 and 2025.

***Reinsurance Premiums Payable***

*Reinsurance Premiums Payable.* As at December 31, 2025, we had reinsurance premiums payables totaling $520.3 million compared to $901.1 million at December 31, 2024, a decrease of $380.8 million, primarily driven by the settlement of the funds withheld balance related to the LPT contract.

**Critical Accounting Policies** 

We believe that the following are critical accounting policies used in the preparation of our consolidated financial statements. A statement of all the significant accounting policies we use to prepare our financial statements is included in the Notes to the consolidated financial statements. If factors such as those described in Item 3D, "Risk Factors" cause actual events to differ from the assumptions used in applying the accounting policies and calculating financial results, there could be a material adverse effect on our operating results, financial condition and liquidity.

***Written Premiums***

Written premiums comprise the estimated premiums on contracts of insurance and reinsurance entered into in the reporting period, except in the case of proportional reinsurance contracts, where written premiums relate only to our estimated proportional share of premiums due on contracts entered into by the ceding company prior to the end of the reporting period.

All premium estimates are reviewed regularly, comparing actual reported premiums to expected ultimate premiums along with a review of the collectability of premiums receivable. Based on management's review, the appropriateness of the premium estimates is evaluated, and any adjustments to these estimates are recorded in the periods in which they become known. Adjustments to original premium estimates could be material and these adjustments may directly and significantly impact earnings in the period they are determined because the subject premium may be fully or substantially earned.

We refer to premiums receivable which are not fixed at the inception of the contract as adjustment premiums. The proportion of adjustment premiums included in the premium estimates varies between business lines with the largest adjustment premiums associated with property and casualty reinsurance business and the smallest with property and liability insurance lines.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Adjustment premiums are most significant in relation to reinsurance contracts. Different considerations apply to non-proportional and proportional treaties as follows:

*Non-proportional treaties.* A large number of the reinsurance contracts we write are written on a non-proportional or excess of loss treaty basis. As the ultimate level of business written by each cedant can only be estimated at the time the reinsurance is placed, the reinsurance contracts generally stipulate a minimum and deposit premium payable under the contract with an adjustable premium determined by variables such as the number of contracts covered by the reinsurance, the total premium received by the cedant and the nature of the exposures assumed. Minimum and deposit premiums generally cover the majority of premiums due under such treaty reinsurance contracts and the adjustable portion of the premium is usually a small portion of the total premium receivable. For excess of loss contracts, the minimum and deposit premium, as defined in the contract, is generally considered to be the best estimate of the contract's written premium at inception. Accordingly, this is the amount we generally record as written premium in the period the underlying risks incept.

During the life of a contract, notifications from cedants and brokers may affect the estimate of ultimate premium and result in either increases or reductions in reported revenue. Changes in estimated adjustable premiums do not generally have a significant impact on short-term liquidity as the payment of adjustment premiums generally occurs after the expiration of a contract.

Many non-proportional treaties also include a provision for the payment to us by the cedant of reinstatement premiums based on loss experience under such contracts. Reinstatement premiums are the premiums charged for the restoration of the reinsurance limit of an excess of loss contract to its full amount after payment by the reinsurer of losses as a result of an occurrence. These premiums relate to the future coverage obtained during the remainder of the initial policy term and are included in revenue in the same period as the corresponding losses.

*Proportional treaties ("treaty pro rata").* Estimates of premiums assumed under treaty pro rata reinsurance contracts are recorded in the period in which the underlying risks are expected to incept and are based on information provided by brokers and ceding companies and estimates of the underlying economic conditions at the time the risk is underwritten. We estimate premiums receivable initially and update our premium estimates regularly throughout the contract term based on treaty statements received from the ceding company.

The reported gross written premiums for treaty pro rata business include estimates of premiums due to us but not yet reported by the cedant because of time delays between contracts being written by our cedants and their submission of treaty statements to us. This additional premium is normally described as pipeline premium. Treaty statements disclose information on the underlying contracts of insurance written by our cedants and are generally submitted on a monthly or quarterly basis, from 30 to 90 days in arrears. In order to report all risks incepting prior to a period end, we estimate the premiums written between the last submitted treaty statement and the period end. Treaty pro rata premiums are written predominantly in our other property, specialty and casualty reinsurance lines of business.

Property treaty pro rata contributed significantly to our Reinsurance segment where we wrote $215.7 million in gross written premiums in 2025 (2024 — $270.6 million), or 11.3% (2024 — 14.3%) of the gross written premiums in our Reinsurance segment. Of this, $227.1 million was reported by the cedants (2024 — $249.1 million), and this was partially offset by $11.4 million related to reductions in premium estimates (2024 — $21.5 million increases in premium estimates). Excluding the impact of costs, such as reinsurance premiums and operating expenses, we estimate that the impact of a $1.0 million increase/decrease in our estimated gross written premiums in our property treaty pro rata business would increase/decrease net income before tax by approximately $0.2 million for the year ended December 31, 2025 (2024 — $0.2 million increase/decrease).

The most likely drivers of change in our premium estimates in decreasing order of magnitude are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in renewal rate or rate of new business acceptances by cedant insurance companies leading to lower or greater volumes of ceded premiums than our estimate, which could result from changes in the relevant primary market that could affect more than one of our cedants or could be a consequence of changes in marketing strategy or risk appetite by a particular cedant;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the rates being charged by cedants; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• differences between the pattern of inception dates assumed in our estimate and the actual pattern of inception dates.

*Earned premiums.* Premiums are recognized as earned over the policy exposure periods. The premium related to the unexpired portion of each policy at the end of the reporting period is included in the balance sheet as unearned premiums.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Accounting for retroactive reinsurance agreements.* Retroactive reinsurance agreements are reinsurance agreements under which a reinsurer agrees to reimburse the Company as a result of past insurable events. For these agreements, the excess of the amounts ultimately collectible under the agreement over the consideration paid is recognized as a deferred gain liability which is amortized into income over the settlement period of the ceded reserves once the paid losses have exceeded the minimum retention. The amount of the deferral is recalculated each period based on actual loss payments and updated estimates of ultimate losses. If the consideration paid exceeds the ultimate losses collectible under the agreement, the net loss on the retroactive reinsurance agreement is recognized within income immediately.

Premiums payable for retroactive reinsurance coverage and meeting the conditions of reinsurance accounting are reported as reinsurance recoverables to the extent that those amounts do not exceed recorded liabilities relating to underlying reinsurance contracts. To the extent that recorded liabilities on an underlying reinsurance contract exceed premiums payable for retroactive coverage, a deferred gain is recognized.

&nbsp;&nbsp;&nbsp;&nbsp;**B. Liquidity and Capital Resources**

**Liquidity** 

Liquidity is a measure of a company's ability to generate cash flows sufficient to meet short-term and long-term cash requirements of its business operations. Management monitors the liquidity of Aspen Holdings and of each of its Operating Subsidiaries and arranges credit facilities to enhance short-term liquidity and capital resources on a stand-by basis. As a holding company, Aspen Holdings relies on dividends and other distributions from its Operating Subsidiaries to provide cash flow to meet ongoing cash requirements, including any future debt service payments and other expenses, and to pay dividends, if any, to our preference and ordinary shareholders.

Aspen Holdings' principal sources of liquidity include (i) cash, cash equivalents and investments, (ii) dividends, capital distributions and interest payments from our Operating Subsidiaries and (iii) our availability under our revolving credit facility and letter of credit facilities. As at December 31, 2025, Aspen Holdings held $374.1 million (December 31, 2024 — $87.8 million) of cash, cash equivalents and investments. Our Operating Subsidiaries collectively paid dividends to Aspen Holdings of $421.2 million and $511.4 million for the twelve months ended December 31, 2025 and 2024, respectively. As at December 31, 2025, we had approximately $798 million of availability for borrowings under our revolving credit facility and letter of credit facilities (December 31, 2024 — $774 million). Management considers the current cash and cash equivalents, together with dividends declared or expected to be declared by subsidiary companies and our credit facilities, sufficient to appropriately satisfy planned and expected liquidity requirements of Aspen Holdings during 2026 and in light of liquidity projections for the period thereafter. Aspen Holdings' liquidity depends on dividends, capital distributions and interest payments from our Operating Subsidiaries. Aspen Holdings also has recourse to the credit facility described under "Letter of Credit Facilities" below.

The ability of our Operating Subsidiaries to pay dividends or other distributions is subject to the laws and regulations applicable to each jurisdiction, as well as the Operating Subsidiaries' need to maintain capital requirements adequate to maintain their insurance and reinsurance operations and their financial strength ratings issued by independent rating agencies. For a further discussion of the various restrictions on our ability and our Operating Subsidiaries' ability to pay dividends, refer to Item 4, "*Business Overview — Certain Regulatory Considerations*." For a discussion of the volatility and liquidity of our other investments, refer to Item 3D, "*Risk Factors — Market and Liquidity Ris*ks," and for a discussion of the impact of insurance losses on our liquidity, refer to Item 3D, "*Risk Factors — (Re)insurance Risk*s" and Item 18, Note 14 of our consolidated financial statements, "*Statutory Requirements and Dividends Restrictions*."

*Operating Subsidiaries.* As at December 31, 2025, the Operating Subsidiaries held $1,362.6 million (December 31, 2024 — $1,110.2 million) in cash and short-term investments that are readily realizable securities. Management monitors the value, currency and duration of cash and investments held by the Operating Subsidiaries to ensure they are able to meet their insurance and other liabilities as they become due and was satisfied that there was a comfortable margin of liquidity as at December 31, 2025 and for the foreseeable future.

On an ongoing basis, our Operating Subsidiaries' sources of funds primarily consist of premiums written, investment income and proceeds from sales and redemptions of investments. Cash is used primarily to pay reinsurance premiums, losses and loss adjustment expenses, brokerage commissions, general and administrative expenses, taxes, interest, dividends and to purchase new investments. The potential for individual large claims and for accumulations of claims from single events means that substantial and unpredictable payments may need to be made within relatively short periods of time.

We ensure that sufficient cash and short-term investments are held to enable us to meet potential claims without liquidating long term investments and adversely affecting our investment return.

We manage these risks by making regular forecasts of the timing and amount of expected cash outflows and ensuring that we maintain sufficient balances in cash and short-term investments to meet these estimates. Notwithstanding this policy, if these cash flow forecasts are incorrect, we could be forced to liquidate investments prior to maturity, potentially at a significant loss.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Where we incur losses in currencies which are not normally held, we will convert funds into the appropriate currencies to mitigate our currency risk and also make funds available to settle claims in local currencies as and when they become due. For local regulatory reasons, we hold assets in trusts which limits our liquidity to some degree. The process of matching assets with liabilities in currency means, however, that at any one time we will hold cash and short-term assets in all major currencies which are available to settle claims.

The liquidity of our Operating Subsidiaries is also affected by the terms of our contractual obligations to policyholders and by undertakings to certain regulatory authorities to facilitate the issue of letters of credit or maintain certain balances in trust funds for the benefit of policyholders, or restricted for other reasons. The following table shows the forms of collateral or other security provided in respect of these obligations and undertakings as at December 31, 2025 and December 31, 2024:

Total net cash flow provided by operations for the twelve months ended December 31, 2025 was $439.0 million, a $115.9 million decrease in cash flow from the equivalent period in 2024. We paid net claims of $1,143.6 million in the twelve months ended December 31, 2025, and derived cash of $339.8 million from investing activities during the period. Cash flows from financing activities were an outflow of $48.7 million, largely due to the payment of preference share dividends of $45.5 million. At December 31, 2025, we had a balance of cash and cash equivalents of $1,658.8 million.

Total net cash flow provided by operations for the twelve months ended December 31, 2024 was $554.9 million, a $230.2 million increase in cash flow from the equivalent period in 2023. The increase in cash generated through operating activities was mainly due to an improved underwriting performance, an improvement on the returns generated by our investment portfolio, and a reduction in claim payments. We paid net claims of $941.5 million in the twelve months ended December 31, 2024, and utilized cash of $352.8 million for investing during the period. Cash flows from financing activities were an outflow of $307.9 million, largely due to the advanced payment of $275.0 million for the redemption of preference shares, and the payment of ordinary and preference share dividends of $249.9 million. This was partially offset by net proceeds of $217.0 million from the issuance of preference shares.

**Capital Resources**

We maintain our capital at an appropriate level as determined by our internal risk appetite and the financial strength required by our customers, regulators and rating agencies, sufficient to address such capital requirements during 2026 and in light of projected capital requirements for the period thereafter. We monitor and review the Aspen Group and the Operating Subsidiaries' capital and liquidity positions on an ongoing basis. The following table shows our capital structures as at December 31, 2025 compared to December 31, 2024:

As at December 31, 2025, total shareholders' equity was $3,625.1 million compared to $3,371.9 million as at December 31, 2024. Our total shareholders' equity as at December 31, 2025 includes three classes of preference shares with a total value of $699.9 million net of share issuance costs (December 31, 2024 — $970.5 million, four classes of preference shares).

Our shareholders' equity, excluding accumulated other comprehensive loss of $198.3 million and Preference Shares, was $3,123.5 million as at December 31, 2025 (December 31, 2024 — $2,791.5 million).

On January 1, 2025, the Company redeemed all 11,000,000 of its issued and outstanding AHL PRC Shares. Each holder of an AHL PRC Share received $25 per preference share, representing an aggregate amount of $275.0 million.

Our preference shares are classified in our balance sheet as equity but may receive a different treatment in some cases under the capital adequacy assessments made by certain rating agencies. Such securities are often referred to as "hybrids" as they have certain attributes of both debt and equity. Management monitors the ratio of the total of debt and hybrids to total capital which was 25.4% as of December 31, 2025 (December 31, 2024 — 34.6%). Total capital is defined as being shareholders' equity plus outstanding debt.

On June 13, 2025, the Company closed its offering of $300.0 million aggregate principal amount of its 5.750% Senior Notes due 2030 (the "2030 Senior Notes"). The net proceeds from the offering, net of debt issuance costs, were $296.8 million, and the proceeds were used to repay the $300.0 million 2026 Term Loan.

As at December 31, 2025, the Company's material debt outstanding was our issued 2030 Senior Notes with a value of $296.8 million.

Upon completion of the Company's IPO in May 2025, the Company introduced the 2025 Equity and Incentive Plan which granted replacement awards in substitution for the MEP legacy share options. As a result, the Company granted 1,306,139 ordinary shares as replacement awards. To satisfy tax withholding and remittance obligations, 301,106 ordinary shares were withheld, resulting in a net issuance of 1,005,033 shares to employees. At the effective time of the Merger, each outstanding and unexercised stock option award (a "Company Option Award") that had an exercise price per Company Share less than the Merger Consideration was canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (a) the amount by which the Merger Consideration exceeded the applicable per share exercise price of the Company Option Award and (b) the number of Company Shares subject to the Company Option Award (a "Restricted Option Award"), and each Company Option Award with an exercise price per Company Share equal to or greater than the Merger Consideration was canceled for no consideration. Additionally, at the Effective Time, each outstanding restricted share unit award (a "Company RSU Award") was canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (x) the Merger Consideration and (y) the number of Company Shares subject to the Company RSU Award (together with the Restricted Option Awards, a "Restricted Cash Award"). Each Restricted Cash Award continued to be subject to the same terms and conditions as the corresponding Company Option Award or Company RSU Award except that, (i) the vested portion of each Restricted Option Award will be paid within 15 days after the applicable vesting date, and (ii) if an individual's employment or service is terminated by the Company or its affiliates without "cause" on or following the Effective Time, all Restricted Cash Awards then-held by such individual will vest in full and be paid within 60 days following the date of such individual's termination of employment, subject to execution and non-revocation of a standard release of claims.

Management monitors the ratio of debt to total capital which was 7.6% as at December 31, 2025 (December 31, 2024 — 8.2%).

During the twelve months ended December 31, 2025, we paid no dividends on our ordinary shares to Parent (December 31, 2024 — $195.0 million). Other than those listed above, there were no principal capital management transactions during 2025 or 2024.

*Access to capital*. Our business operations are in part dependent on our financial strength, the opinions of the independent rating agencies thereof, as discussed elsewhere in this report, and the market's perception thereof, as measured by total shareholders' equity, which was $3,625.1 million as at December 31, 2025 (December 31, 2024 — $3,371.9 million). Our ability to access the capital markets is dependent on, among other things, our operating results, market conditions and our perceived financial strength. We regularly monitor our capital and financial position, as well as investment and securities market conditions, both in general and with respect to Aspen Holdings' securities. Our ordinary shares, preference shares and depositary shares are listed on the NYSE.

Not applicable.

&nbsp;&nbsp;&nbsp;&nbsp;**D. Trend Information**

We actively manage our insurance and reinsurance portfolios across market cycles and identify the most attractive risk versus return opportunities to allocate capital. We adopt a dynamic capital allocation approach, utilizing our strong balance sheet and our multiple platforms across the United States, the United Kingdom ("U.K."), Lloyd's of London ("Lloyd's") and Bermuda to match risk with the most appropriate source of capital, and to drive efficiencies and optimal outcomes for our customers. Our ability to offer our broker and client partners holistic and customized solutions across our entire platform of Insurance and Reinsurance, and third-party capital offerings through ACM, provides us the opportunity to execute larger, more complex deals which frequently result in more attractive terms and conditions.

**Our Markets, General Economic Conditions and Opportunities**

We operate within the global (re)insurance market, where we have significant opportunities to capture attractive risk-adjusted returns across the cycle through our multi-platform capabilities. The global macroeconomic and social environment continues to drive demand for increasingly complex (re)insurance solutions delivered as a joined-up offering, which is where we thrive. In recent years, rate increases have been driven by the increased frequency and severity of natural catastrophe events globally (impacted by changing weather patterns), inflation (both social and economic), increased geopolitical tensions and other risks that have grown and emerged, increasing the demand for specialty solutions. As a result, market conditions remain attractive, with the global commercial insurance industry seeing moderate price increases (according to WTW's Commercial Lines Insurance Pricing Survey Q3 2025), although there is softening in certain classes of business.

We generally expect these market conditions will persist, as they are driven by uncorrelated and continuing macroeconomic and social dynamics. This will provide opportunities for us to deliver profitable growth as we target new business and clients at favorable risk adjusted rates and with improved terms and conditions, while maintaining disciplined risk selection. Furthermore, our chosen lines of business within Insurance have high barriers to entry requiring the bespoke tailoring of products and the need for specialized and experienced underwriters with tenured distribution relationships.

The potential for sustained higher interest rate environment also provides additional tailwinds for our business. Higher returns from our fixed income portfolio complement our underwriting income with attractive investment income and contribute to our ability to generate strong risk-adjusted returns for our shareholders. With a high-quality, actively managed fixed income portfolio of relatively short duration of 3.4 years as of December 31, 2025, we are well placed to take advantage of market fluctuations and higher relative attractive investment yields as we rotate and reinvest.

**Insurance and Reinsurance Market Trends and Developments**

*Insurance Segment*: While market conditions remain competitive and pricing momentum continues to moderate across the insurance sector, our market relevance and positioning remain strong across all portfolios (casualty and liability lines, financial and professional lines, specialty, and first-party business). Inflationary pressures, both social and economic, alongside ongoing geo- and socio-political uncertainty remain key considerations in risk selection and pricing, reinforcing the importance of active exposure management. Rate momentum has softened, with increased pressure evident in Property, Specialty, and certain Financial and Professional Lines, driven primarily by heightened competition and the introduction of new capacity, but we continue to demonstrate relative resilience. Casualty and liability lines have continued to achieve rate increases, marking seven consecutive years of positive movement and a meaningful cumulative impact. Given ongoing concerns around social inflation, litigation funding, and large mass-tort verdicts, growth in casualty and liability remains measured. Maintaining underwriting discipline, portfolio balance and strong trading relationships across a diversified portfolio remains critical as market conditions normalize.

*Reinsurance Segmen*t: The reinsurance market in 2025 was characterized by heightened competition, specifically within property and specialty lines. The property catastrophe market experienced increased competition at January renewals which resulted in average rate reductions in excess of 10% across global markets. These conditions were driven in part by lighter than average 2025 US hurricane season which allowed reinsurers to deploy additional capital. Despite increased competition, markets remained generally disciplined as evidenced by stable retentions and lack of significant slippage in terms and conditions. We still believe the business is adequately priced, but would expect rate pressure to persist through the rest of 2026 renewal cycle. In other property reinsurance lines, cedants were able to secure higher ceding commissions on proportional treaties due to strong underlying performance and abundant capacity. We expect to continue observing gaps in underlying subject business estimates, particularly in the commercial / excess space as additional market participants including managing general agents adds capacity. Specialty lines also experienced heightened competition as larger, diversified markets seek to deploy capital outside of property and casualty lines to pursue growth. Conversely, casualty reinsurance markets continue to face increased loss trends due primarily to ongoing social inflation. The introduction and continued adoption of casualty reinsurance sidecars has further increased competitive pressure, as cedants increasingly access third-party capital.

We actively monitor portfolio performance and maintain underwriting discipline, taking corrective action where risk-adjusted returns are no longer considered appropriate.

Inflation, climate change and exposure to man-made events are expected to continue to impact global insurance markets. Refer to Item 3D, "*Risk Factor*s" and "*Cautionary Statement Regarding Forward-Looking Statement*s" included in this report.

&nbsp;&nbsp;&nbsp;&nbsp;**E. Critical Accounting Estimates**

Our consolidated financial statements contain certain amounts that are inherently subjective in nature and require management to make assumptions and best estimates to determine the reported values. We believe that the following critical accounting estimates are the most significant estimates used in the preparation of our consolidated financial statements.

**<u>Reserving Approach</u>**

We are required by U.S. GAAP to establish loss reserves for the estimated unpaid portion of the ultimate liability for losses and loss adjustment expenses ("ultimate losses") under the terms of our policies and agreements with our insured and reinsured customers. Our loss reserves comprise the following components:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the cost of claims reported to us but not yet paid, known as case reserves ("case reserves");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reserves to cover the anticipated cost of IBNR claims. Within this, we also include the potential development of reported claims; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the expenses associated with settling claims, including legal and other fees and the general expenses of administering the claims adjustment process, known as the loss adjustment expenses ("LAE").

*Case Reserves.* For reported claims, reserves are established on a case-by-case basis within the parameters of coverage provided in the insurance policy or reinsurance agreement. The method of establishing case reserves for reported claims differs among our operations. With respect to our insurance operations, we are advised of potential insured losses and our claims handlers' record reserves for the estimated amount of the expected indemnity settlement, loss adjustment expenses and cost of defense where appropriate. The reserve estimate reflects the judgment of the claims personnel and is based on claim information obtained to date, general reserving practices, the experience and knowledge of the claims personnel regarding the nature of the specific claim and where appropriate and available, advice from legal counsel, loss adjusters and other claims experts.

With respect to our reinsurance claims operations, claims handlers set case reserves for reported claims generally based on the claims reports received from our ceding companies and take into consideration our cedants' own reserve recommendations and our prior loss experience with the cedant. Additional case reserves ("ACR"), in addition to the cedants' own recommended reserves, may be established by us to reflect our estimated ultimate cost of a loss. ACRs are generally the result of either a claims handler's own experience and knowledge of handling similar claims, general reserving practices or the result of reserve recommendations following an audit of cedants' reserves.

Case reserves are based on a subjective judgment of facts and circumstances and are established for the purposes of internal reserving only. Accordingly, they do not represent a commitment to any course of conduct or admission of liability on our behalf in relation to any specific claim.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*IBNR Reserves.* The need for IBNR reserves arises from time lags between when a loss occurs and when it is actually reported and settled. By definition, we do not have specific information on IBNR claims so they need to be estimated by actuarial methodologies. IBNR reserves are therefore generally calculated at a class of business level and cannot generally be identified as reserves for a particular loss or contract. We calculate IBNR reserves by class of business within each line of business. Where appropriate, analyses may be conducted on sub-sets of a class of business. IBNR reserves are calculated by projecting our ultimate losses on each class of business and subtracting paid losses and case reserves. IBNR reserves also cover the anticipated cost of claims incurred but not reported, within this we also include any potential development of reported claims. Over recent years, we have begun to place greater reliance on our actual actuarial experience for our long-tail lines of business that we have written since our inception in 2002. We believe that our earliest accident years are now capable of providing us with meaningful actuarial indications. Estimates and judgments for new insurance and reinsurance lines of business are more difficult to make than those made for more mature lines of business because we have more limited historical information through December 31, 2025.

*Sources of Information.* Claims information received typically includes the loss date, details of the claim, the recommended reserve and reports from the loss adjusters dealing with the claim. In respect of pro rata treaties and any business written through managing general agents, we receive regular statements (bordereaux) which provide paid and outstanding claims information, often with large losses separately identified. Following widely reported loss events, such as catastrophes, we adopt a proactive approach to establish our likely exposure to claims by reviewing policy listings and contacting brokers and policyholders as appropriate.

*Actuarial Methodologies.* The main projection methodologies that are used by our actuaries are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Initial expected loss ratio ("IELR") method:* This method calculates an estimate of ultimate losses by applying an estimated loss ratio to an estimate of ultimate earned premium for each accident year. The estimated loss ratio may be based on pricing information and/or industry data and/or historical claims experience revalued to the year under review.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Bornhuetter-Ferguson ("BF") method:* The BF method uses as a starting point an assumed IELR and blends in the loss ratio, which is implied by the claims experience to date using benchmark loss development patterns on paid claims data ("Paid BF") or reported claims data ("Reported BF"). Although the method tends to provide less volatile indications at early stages of development and reflects changes in the external environment, it can be slow to react to emerging loss development and can, if the IELR proves to be inaccurate, produce loss estimates which take longer to converge with the final settlement value of loss.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Loss development ("Chain Ladder") method:* This method uses actual loss data and the historical development profiles on older accident years to project more recent, less developed years to their ultimate position.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Exposure-based method:* This method is typically used for specific large catastrophic events such as a major hurricane. All exposure is identified and we work with known market information and information from our cedants to determine a percentage of the exposure to be taken as the ultimate loss.

In addition to these methodologies, our actuaries may use other approaches depending upon the characteristics of the class of business and available data. In addition, as required pursuant to Bermuda law, we have appointed a third party as loss reserve specialist for Aspen Bermuda Limited and as group actuary in relation to Aspen Holdings, in each case to provide an external view on the Company's reserves.

In general terms, the IELR method is most appropriate for classes of business and/or accident years where the actual paid or reported loss experience is not yet mature enough to modify our initial expectations of the ultimate loss ratios. Typical examples would be recent accident years for classes of business in casualty reinsurance. The BF method is generally appropriate where there are few reported claims and a relatively less stable pattern of reported losses. Typical examples would be our treaty risk excess class of business in our Reinsurance segment and marine hull class of business in our Insurance segment. The Chain Ladder method is appropriate when there are relatively stable patterns of loss emergence and a relatively large number of reported claims. Typical examples are the U.K. commercial property and U.K. commercial liability classes of business in our international insurance business.

*Reserving Procedures and Process.* Our actuaries calculate the IELR, BF and Chain Ladder and, if appropriate, other methods for each class of business and each accident year. They then calculate a single point actuarial central estimate ("ultimate") for each class of business. The actuarial methodologies involve significant subjective judgments reflecting many factors, including but not limited to, changes in legislative conditions, changes in judicial interpretation of legal liability policy coverages and heightened inflation. Our actuaries collaborate with our underwriting, claims, legal and finance teams in identifying factors which are incorporated in their range of ultimates in which management's best estimate is most likely to fall.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

There are no differences between our year-end and our quarterly internal reserving procedures and processes because our actuaries perform the basic projections and analyses described above for each class of business quarterly.

*Selection of Reported Gross Reserves.* The Reserve Committee signs off on the group-level reserves, which reflects, amongst other matters, key areas of reserving uncertainty within the group actuarial central estimate. Levels of uncertainty are factored into the management best estimate, which provides the basis for management's recommendation to the Audit Committee and the Board regarding the reserve amounts to be recorded in the financial statements.

As at December 31, 2025, the Reserve Committee was chaired by the Group Chief Actuarial Officer and its membership includes members of senior management from various functions of the business.

Each significant class of business is reviewed in detail by management through its Reserve Committee at least once a year. The timing of such reviews varies throughout the year. Additionally, we review the emergence of actual losses relative to expectations every fiscal quarter for all classes of business. If warranted from this analysis, we may accelerate the timing of our detailed actuarial reviews.

*Uncertainties.* While the management selected reserves make a reasonable provision for unpaid loss and loss adjustment expense obligations, we note that the process of estimating required reserves, by its very nature, involves uncertainty and therefore the ultimate claims may fall outside the actuarial range. The level of uncertainty can be influenced by such factors as the existence of coverage with long duration reporting patterns and changes in claims handling practices, as well as the other factors described above.

Given many of the coverages underwritten involve claims that may not be ultimately settled for many years after they are incurred, subjective judgments as to the ultimate exposure to losses are an integral and necessary component of the loss reserving process. We review our reserves regularly, using a variety of statistical and actuarial techniques to analyze current claims costs, frequency and severity data, and prevailing economic, social and legal factors. Reserves established in prior periods are adjusted as claims experience develops and new information becomes available.

Estimates of IBNR are generally subject to a greater degree of uncertainty than estimates of the cost of settling claims already notified to us, where more information about the claim event is generally available. IBNR claims often may not be apparent to the insured until many years after the event giving rise to the claims has happened. Classes of business where the IBNR proportion of the total reserve is high, such as casualty insurance, will typically display greater variations between initial estimates and final outcomes because of the greater degree of difficulty of estimating these reserves.

Classes of business where claims are typically reported relatively quickly after the claim event tend to display lower levels of volatility between initial estimates and final outcomes. Reinsurance claims are subject to a longer time lag both in their reporting and in their time to final settlement. The time lag is a factor which is included in the projections to ultimate claims within the actuarial analyses and helps to explain why in general a higher proportion of the initial reinsurance reserves are represented by IBNR than for insurance reserves for business in the same class. Delays in receiving information from cedants are an expected part of normal business operations and are included within the statistical estimate of IBNR to the extent that current levels of backlog are consistent with historical data. Currently, there are no processing backlogs which would materially affect our financial statements.

Allowance is made, however, for changes or uncertainties which may create distortions in the underlying statistics or which might cause the cost of unsettled claims to increase or reduce when compared with the cost of previously settled claims, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in our processes which might accelerate or slow down the development and/or recording of paid or incurred claims;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the legal environment (including challenges to tort reform);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the effects of inflation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the mix of business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the impact of large losses; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in our cedants' reserving methodologies.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

These factors are incorporated in the management's best estimate of reserves. We take all reasonable steps to ensure that we utilize all appropriate information and actuarial techniques in establishing our IBNR reserves. However, given the uncertainty in establishing claims liabilities, it is likely that the final outcome will prove to be different from the original provision established at the balance sheet date. Changes to our previous estimates of prior period loss reserves impact the reported calendar year underwriting results by worsening our reported results if the prior year reserves prove to be deficient or improving our reported results if the prior year reserves prove to be redundant. As at December 31, 2025, a 5% change in the gross reserve for IBNR losses would have equated to a change of approximately $294.8 million (2024 — $262.4 million) in loss reserves.

A 5% change in our net loss reserves equates to $222.2 million and represents 6.1% of shareholders' equity as at December 31, 2025.

There are specific areas of our selected reserves which have additional uncertainty associated with them. Refer to Item 3D, "*Risk Factors — (Re)insurance Risks — Our financial condition and operating results may be adversely affected if actual claims exceed our loss reserves*" for a discussion of the specific areas of our selected reserves which have additional uncertainty. In each case, management believes they have selected an appropriate best estimate based on current information and current analyses.

*Loss Reserving Sensitivity Analysis.* The most significant key assumptions identified in the reserving process are that (i) the historic loss development and trend experience is assumed to be indicative of future loss development and trends, (ii) the information developed from internal and independent external sources can be used to develop meaningful estimates of the initial expected ultimate loss ratios, and (iii) no significant losses or types of losses will emerge that are not represented in either the initial expected loss ratios or the historical development patterns.

We believe that there is potentially significant risk in estimating loss reserves for long-tail lines of business and for immature accident years that may not be adequately captured through traditional actuarial projection methodologies. As discussed above, these methodologies usually rely heavily on projections of prior year trends into the future. In selecting our best estimate of future liabilities, we consider both the results of actuarial point estimates of loss reserves in addition to the stochastic distribution of reserves. In determining the appropriate best estimate, we review (i) the result of bottom up analysis by accident year reflecting the impact of parameter uncertainty in actuarial calculations, and (ii) specific qualitative information on events that may have an effect on future claims development but which may not have been adequately reflected in actuarial best estimates, such as the potential for outstanding litigation or claims practices of cedants to have an adverse impact.

*Effect if Actual Results Differ From Assumptions.* Given the risks and uncertainties associated with the process for estimating reserves for losses and loss adjustment expenses, management has performed an evaluation of the potential variability in loss reserves and the impact this variability may have on reported results, financial condition and liquidity. Because of the inherent uncertainties discussed above, we have developed a reserving philosophy which attempts to incorporate prudent assumptions and estimates.

Management's best estimate of the net reserve for losses and loss adjustment expenses as at December 31, 2025 was $4,443.1 million. The following tables show the effect on estimated net reserves for losses and loss adjustment expenses as at December 31, 2025 of a change in two of the most critical assumptions in establishing reserves: (i) loss emergence patterns, accelerated or decelerated by three and six months; and (ii) expected loss ratios varied by plus or minus five and ten percent. Accelerated loss emergence patterns indicates a higher development percentage of losses, therefore requiring lower IBNR than previously expected and hence resulting in a lower ultimate.

Management believes that these scenarios present a reasonable range of variability around the booked reserves using standard actuarial techniques. Loss reserves may vary beyond these scenarios in periods of heightened or reduced claim activity. The reserves resulting from the changes in the assumptions are not additive and should be considered separately. The following tables vary the assumptions employed therein independently. In addition, the tables below do not adjust any parameters other than the ones described above and do not reflect any secondary effects, such as changes in net investment income or other items in the consolidated statements of operations.

---

The most significant variance in the above scenarios (i.e., a six month deceleration of loss emergence patterns) would have the effect of increasing the net reserve for losses and loss adjustment expenses by $538.0 million.

Management believes that the reserve for losses and loss adjustment expenses is sufficient to cover expected claims incurred before the reporting date on the basis of the methodologies and judgments used to support its estimates. However, there can be no assurance that actual payments will not vary significantly from total reserves. The reserve for losses and loss adjustment expenses and the methodology of estimating such reserve are regularly reviewed and updated as new information becomes known. Any resulting adjustments are reflected in income in the period in which they become known.

**<u>Recoverability of Deferred Tax Asset</u>**

In assessing the recoverability of deferred tax assets, and the recognition/de-recognition of associated valuation allowances, the Company considered a number of factors that required significant judgement, such as successive years of achieving three-year cumulative net taxable income, recent operating trends, growth and profitability forecasts, premium and investment return assumptions, etc. when making its determination. For the year ended December 31, 2025, the valuation allowance for Aspen UK was reduced by $106.6 million since it was the third consecutive year meeting the aforementioned benchmarks. At December 31, 2025, the valuation allowance reflects management's assessment that it is more likely than not that the deferred tax assets in the branches of the U.K. and Bermuda operating subsidiaries, on foreign tax credit carryforwards and on trapped net operating losses will not be realized. Management believe that all other deferred tax assets will more likely than not be fully utilized over time.

**<u>Valuation of Investments Measured Using Significant Unobservable Inputs</u>**

The Company's estimates of fair value for financial assets and liabilities are based on the framework established in the fair value accounting guidance included in ASC Topic 820, "Fair Value Measurements and Disclosures." The framework prioritizes the inputs, which refer broadly to assumptions market participants would use in pricing an asset or liability.

The Company considers prices for actively traded securities to be derived based on quoted prices in an active market for identical assets.

The Company considers prices for other securities that may not be as actively traded which are priced via pricing services, vendors and broker-dealers, or with reference to interest rates and yield curves, to be derived based on inputs that are observable for the asset, either directly or indirectly.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

The Company considers securities, other financial instruments, privately-held investments and derivative insurance contracts subject to fair value measurement whose valuation is derived by valuation models to be based largely on unobservable inputs. Unobservable inputs are assumptions used by the Company using the best available information at the time of making these valuation assumptions. Level 3 financial instruments have the least use of observable market inputs used to determine fair value. As at December 31, 2025, the Company classified privately-held investments of $172.3 million as Level 3 as a result of significant unobservable inputs used to determine fair value (2024 — $311.0 million).

Privately-held investments are initially valued at cost or transaction value which approximates fair value. In subsequent measurement periods, the fair values of these securities are determined using discounted cash flow models. These models include inputs that are specific to each investment. The inputs used in the fair value measurements include dividend or interest rates and appropriate discount rates. The selection of an appropriate discount rate is judgmental and is the most significant unobservable input used in the valuation of these securities. A significant increase (decrease) in this input in isolation could result in significantly lower (higher) fair value measurement for privately-held investments. In order to assess the reasonableness of the inputs the Company uses in the discounted cash flow models, the Company maintains an understanding of current market conditions, issuer specific information that may impact future cash flows as well as collaboration with independent vendors for most securities to assess the reasonableness of the discount rate being used.

The Company's other investments represent our investments in investment funds. Adjustments to the fair values are made based on the net asset value of the investments. The net valuation criteria established by the manager of such investments are established in accordance with the governing documents and the asset manager's valuation guidelines, which include: the discounted cash flows method and the performance multiple approach, which uses a multiple derived from market data of comparable companies or assets to produce operating performance metrics. Alternative valuation methodologies may be employed for investments with unusual characteristics.

See also "*Quantitative and Qualitative Disclosures about Market Risk*" in Item 11 of this report for further details on interest rate and credit spread risk and a sensitivity analysis of interest rate on the valuation of the Company's investments.

(1)&nbsp;&nbsp;&nbsp;&nbsp;The long-term debt accrues interest at 5.750% on the $300.0 million Senior Notes due 2030 (the "2030 Senior Notes").

(2)&nbsp;&nbsp;&nbsp;&nbsp;In estimating the time intervals into which payments of our reserve for losses and loss adjustment expenses fall, as set out above, we have utilized actuarial assessed payment patterns. By the nature of the insurance and reinsurance contracts under which these liabilities are assumed, there can be no certainty that actual payments will fall in the periods shown and there could be a material acceleration or deceleration of claims payments depending on factors outside our control. The total amount of payments in respect of our reserves, as well as the timing of such payments, may differ materially from our current estimates for the reasons set out under Item 18, Note 2 of our consolidated financial statements, "*Basis of Presentation and Significant Accounting Policies - Reserves*."

(3)&nbsp;&nbsp;&nbsp;&nbsp;The reserve for losses and loss adjustment expenses presented above are shown on a gross basis, and do not reflect anticipated recoveries from reinsurers.

The inclusion of forward-looking statements in this report should not be considered as a representation by us that current plans or expectations will be achieved. Forward-looking statements speak only as of the date on which they are made and we undertake 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.

**Effects of Inflation** 

The future expectations for economic inflation are uncertain at the present and there is a risk of inflation being elevated for an extended period, which could further increase claims and claim expenses, impact the performance of our investment portfolio or have other adverse effects. The onset, duration and severity of an inflationary period cannot be estimated with precision.

The potential exists after a catastrophe or other large property loss for the development of inflationary pressures in a local economy as the demand for services, such as construction, typically surges. The cost of settling claims may also be increased by global commodity price inflation. We seek to take both these factors into account when setting reserves for any events where we think they may be material. In addition, this risk may be exacerbated by the steps taken by governments and central banks throughout the world in responding to the COVID-19 pandemic and any future pandemics, the impact from the war in Ukraine, global supply chain issues.

The anticipated effects of inflation are considered in our pricing models, reserving processes and exposure management, across all lines of business and types of loss, including natural catastrophe events, and this includes assumptions about future payments for settlement of claims and claims-handling expenses. To the extent inflation causes these costs to increase above reserves established for these claims, we will be required to increase our loss reserves with a corresponding reduction in earnings.

The actual effects of the current and potential future increase in inflation on our results cannot be accurately known until, among other items, claims are ultimately settled.

In addition to general price inflation, social inflation has increased, and, accordingly, we may be exposed to a persisting long-term upwards trend in the cost of judicial awards for damages. We seek to take this into account in our pricing and reserving of our lines of business, notably on our casualty business.

We also seek to take into account the projected impact of inflation on the likely actions of central banks in the setting of short-term interest rates and consequent effects on the yields and prices of fixed interest securities. A potentially prolonged high inflationary environment poses a risk to the performance of our investment portfolio or have other adverse effects. In particular, rising inflation, interest rates and bond yields may result in a decrease in the market value of certain of our fixed interest investments. Refer to Item 3D, "*Risk Factors — Market and Liquidity Risks — Our investments are subject to interest rate, credit, and real estate related risks, which may adversely affect our net income and may adversely affect the adequacy of our capital*" and also to "*Risk Factors — Risks Related to Our Business — We may be adversely impacted by economic inflation and social inflation*."

&nbsp;&nbsp;&nbsp;&nbsp;**H. Reconciliation of 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.

*Average equity*, a non-GAAP financial measure, is used in calculating ordinary shareholders return on average equity. Average equity is calculated by taking the arithmetic average of total shareholders' equity on a quarterly basis for the stated periods excluding the average value of preference shares less issue expenses. Operating return on average equity is calculated by dividing operating income by average equity.

| Preference shares less issue expenses | (699.9) | (970.5) | (753.5) |
| Average adjustment | (277.8) | (174.0) | (336.2) |
| &nbsp;&nbsp;&nbsp;Average equity | $2647.4 | $2227.4 | $1818.8 |
| Operating return on average equity | 15.9% | 19.4% | 20.2% |
| Net income, adjusted for preference share dividends, on average equity | 11.0% | 19.4% | 26.7% |
| Net income, adjusted for preference share dividends, on closing equity | 9.9% | 18.0% | 22.5% |

---

*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 LPT contract 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, net foreign exchange gains or losses, including net realized and unrealized gains and losses from foreign exchange contracts, net realized and unrealized gains or losses on investments, non-operating expenses and income, and preference share redemption costs. Non-operating expenses include expenses incurred in connection with non-recurring projects, such as consulting fees and other non-recurring transformation program costs, and are included within general, administrative and corporate expenses in the consolidated statement of operations. The non-operating income tax (benefit)/expense is calculated on the above items by applying the statutory tax rate for each of the Company's material tax jurisdictions to the relevant income/expense for those same jurisdictions. The non-operating income tax (benefit)/expense is included within income tax benefit/(expense) in the consolidated statement of operations.

Aspen excludes the items above from its calculation of operating income because management believes 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 analyze Aspen's results of operations in a manner consistent with how management analyzes Aspen's underlying business performance. Operating income should not be viewed as a substitute for GAAP net income.

*General Insurance:*

*Underwriting result or income/ 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 underwriting expenses. Underwriting expenses are the sum of losses and loss adjustment 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 losses and loss adjustment expenses* is a non-GAAP financial measure. It is the sum of current accident year losses, catastrophe losses and prior year reserve strengthening/(releases) post LPT years. Adjusted losses and loss adjustment expenses excludes the change in the deferred gain on retroactive reinsurance contracts and represents the performance of our business for accident years 2020 onwards, which management believes reflects the underlying underwriting performance of the ongoing business.

*Adjusted underwriting income or loss* is a non-GAAP financial measure. It is the underwriting income or loss adjusted for the change in deferred gain on retroactive reinsurance contracts in order to economically match the loss recoveries under the LPT contract 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 management believes reflects the underlying underwriting performance of the ongoing portfolio.

Along with most property and casualty insurance companies, we use the loss ratio, the expense ratio and the combined ratio as measures of underwriting performance. These ratios are relative measurements that describe, for every $100 of net earned premiums, the amount of losses and loss adjustment expenses, and the amount of other underwriting expenses that would be incurred. A combined ratio of less than 100 indicates an underwriting income and a combined ratio of over 100 indicates an underwriting loss.

*Combined ratio* is the sum of the loss ratio and 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.

------

<u>[Table of](#ic234cba0d6764b21b5bf3826335055fe_7)</u><u>[Contents](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Adjusted combined ratio* is a non-GAAP financial measure. It 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.

Combined ratios differ from U.S. statutory combined ratios primarily due to the deferral of certain third-party acquisition expenses for GAAP reporting purposes and the use of net earned premiums rather than net written premiums in the denominator when calculating the acquisition cost and the general and administrative expense ratios.

&nbsp;&nbsp;&nbsp;&nbsp;**B. Compensation**

*Director Compensation*

The Company paid approximately $1.5 million as aggregate compensation to non-executive directors for their services to the Company during 2025. In the case of Albert Beer and Theresa Froehlich, this also includes fees paid for their services as directors of certain of the Company's subsidiaries.

Mr. Cloutier, who served as Group Chief Executive Officer and Executive Chairman of the Board until February 2026, and Mr. Dunleavy, who served as Group President until February 2026, did not receive any compensation for their services as directors in 2025. Likewise, Messrs. Humphreys, Lohr, and Saffer, who ceased as directors of the Company in February 2026, did not receive any compensation for their service as directors in 2025. All directors are reimbursed for any travel and other related expenses incurred while attending Board meetings.

The compensation so described relates to compensation paid to the non-executive directors of the Company in place prior to the effective time of the Merger, in February 2026. For the avoidance of doubt, the compensation so described does not reflect any compensation paid to non-executive directors of the Company following the effective time of the Merger. Refer to Item 6A for more details.

*Senior Management Compensation*

In relation to 2025, the members of senior management identified in Item 6A (including Mr. Cloutier) were awarded approximately $30.0 million in aggregate compensation. This is comprised of: (i) base salary of approximately $6.1 million; (ii) discretionary bonuses, which include annual bonuses paid in 2026 for service during 2025 and, amongst other factors, improved business performance, of approximately $21.5 million; (iii) equity-related compensation of $8.1 million, comprising restricted share units and options; and (iv) pension, retirement, and other benefits of approximately $2.4 million.

The compensation so described relates to compensation paid to the senior management of the Company in place prior to the effective time of the Merger, in February 2026. For the avoidance of doubt, the compensation so described does not reflect any compensation paid to the senior management of the Company following the effective time of the Merger. Refer to Item 6A for more details.

2025 Equity and Incentive Plan & Share Incentive Plan

In connection with our initial public offering in May 2025, we adopted the Aspen Insurance Holdings Limited 2025 Equity and Incentive Plan (the "2025 Incentive Plan"), which provides for the grant of incentive share options, nonqualified share options, share appreciation rights, restricted shares awards, restricted share units, other share awards, and performance awards. Officers, non-employee directors, employees and other service providers, and those expected to become officers, non-employee directors, employees and other service providers, were eligible to receive such awards, as the Board, or a sub-committee thereof, may determine from time to time. Also in connection with our initial public offering in May 2025, we adopted a Share Incentive Plan, under which employees of the Company were also eligible to receive share-based awards (the "U.K. SIP"). Following the Merger, the Company made certain filings with the SEC to terminate the registration statement associated with the 2025 Incentive Plan and all offerings of its securities pursuant thereto (the "S-8 Amendment"), and to remove and withdraw from registration all securities registered pursuant to the registration statement that remain unsold as of the date of the filing, and to terminate the 2025 Incentive Plan and the U.K. SIP.

At the Effective Time, each outstanding and unexercised stock option award (a "Company Option Award") that had an exercise price per Company Share less than the Merger Consideration was canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (a) the amount by which the Merger Consideration exceeded the applicable per share exercise price of the Company Option Award and (b) the number of Company Shares subject to the Company Option Award (a "Restricted Option Award"), and each Company Option Award with an exercise price per Company Share equal to or greater than the Merger Consideration will be canceled for no consideration. Additionally, at the Effective Time, each outstanding restricted share unit award (a "Company RSU Award") was canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (x) the Merger Consideration and (y) the number of Company Shares subject to the Company RSU Award (together with the Restricted Option Awards, a "Restricted Cash Award"). Each Restricted Cash Award will continue to be subject to the same terms and conditions as the corresponding Company Option Award or Company RSU Award except that, (i) the vested portion of each Restricted Option Award will be paid within 15 days after the applicable vesting date, and (ii) if an individual's employment or service is terminated by the Company or its affiliates without "cause" on or following the Effective Time, all Restricted Cash Awards then-held by such individual will vest in full and be paid within 60 days following the date of such individual's termination of employment, subject to execution and non-revocation of a standard release of claims.

*Audit Committee*

As of December 31, 2025, the Audit Committee of the Company was comprised of Messrs. Lightowler (Chair), Beer and Altmaier, all of whom were independent for purposes of the NYSE rules and Rule 10A-3 under the Securities Exchange Act of 1934, as amended.

Shortly following and in connection with the Merger, the composition of the Audit Committee was updated such that, as at the date of this report, the Audit Committee is comprised of Messrs. Babcock (Chair) and Altmaier, both of whom are independent for purposes of the NYSE rules and Rule 10A-3 under the Securities Exchange Act of 1934, as amended. The Board determined that each of Messrs. Babcock and Altmaier are financially literate as such term is defined by applicable NYSE and SEC requirements. In addition, the Board has determined that Mr. Babcock qualified as having accounting or related financial management expertise pursuant to NYSE requirements and is an "audit committee financial expert" pursuant to the rules and regulations of the SEC. Pursuant to its charter, the Audit Committee has general responsibility to assist the Board in its oversight of: (i) the integrity of the Company's financial statements, including the accounting and financial reporting process of the Company and audits of the Company's financial statements; (ii) the Company's compliance with legal and regulatory requirements, as well as conflict of interest matters (to the extent not within the remit of the Conflicts Committee); (iii) the independent auditors' qualifications, performance and independence; and (iv) the performance of the Company's internal audit function. Among other things, the Audit Committee annually reviews and makes recommendations to the Board as to their selection and reviews the plan, fees (as otherwise determined by management) and results of the audit of the independent auditors, as well as the fees (as otherwise determined by management) and proposed scope of any non-audit services to be provided by the independent auditor. Such matters may be considered pursuant to the terms of the pre-approval policy adopted by the Board. The Audit Committee also is directly responsible for the appointment, compensation, retention and oversight of the work of the Company's independent auditors (including resolution of disagreements between management and the auditor regarding financial reporting), and the Company's independent auditors must report directly to the Audit Committee.

As at December 31, 2025, the Board determined that each of the members of the Audit Committee is financially literate as such term is defined by applicable NYSE and SEC requirements. In addition, the Board has determined that Mr. Lightowler qualified as having accounting or related financial management expertise pursuant to NYSE requirements and is an "audit committee financial expert" pursuant to the rules and regulations of the SEC.

*Other Standing Committees*

As at December 31, 2025, in addition to the Audit Committee, the Board maintained a Risk Committee, Investment Committee, Conflicts Committee, Compensation Committee and Nominating & Corporate Governance Committee. Shortly following and in connection with the Merger, the following committees were dissolved: Investment Committee, Conflicts Committee, Compensation Committee and Nominating & Corporate Governance Committee. As at the date of this report, the Board maintains an Audit Committee and a Risk Committee. See "*Item 4B - Business Overview - Risk Management*" for more information regarding these committees and "*Item 16G – Corporate Governanc*e" for a summary of ways in which our corporate governance practices differ from those followed by U.S. domestic companies listed on the NYSE.

Reference is made to Item 18 of this report, for the consolidated financial statements and reports of the Company and the Notes thereto, as well as the schedules to the consolidated financial statements.

**<u>Dividends</u>**

The Company's dividend approach is to declare and pay any dividends on our Company Ordinary Shares at the discretion of the Board, which may take into account general and economic conditions, our financial condition and results of operations, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions and implications on the payment of dividends by us to our shareholders or by our subsidiaries to us, including restrictions under any of our then outstanding indebtedness, the terms of our Preference Shares (as defined below) and such other factors as the Board may deem relevant. If we elect to pay dividends in the future, we may reduce or discontinue entirely the payment of such dividends at any time.

At the Board's discretion, we declare and pay quarterly dividends on our 5.625% Perpetual Non-Cumulative Preference Shares (NYSE: AHL PRD) ("AHL PRD Shares"), our 5.625% Perpetual Non-Cumulative Preference Shares ("AHL PRE Shares"), which are represented by depositary shares, each representing 1/1000th interest in an AHL PRE Share (NYSE: AHL PRE), and our depositary shares, each representing a 1/1000th interest in our 7.00% Perpetual Non-Cumulative Preference Shares (NYSE: AHL PRF) ("AHL PRF Shares" and, together with our AHL PRD Shares and our AHL PRE Shares, the "Preference Shares"). Such Preference Shares rank senior to our ordinary shares with respect to the payment of dividends and distributions of assets upon our liquidation, dissolution or winding-up.

On November 26, 2024, the Company issued 9,000,000 depositary shares, each of which represents 1/1000<sup>th</sup> interest in a share of the 7.00% Perpetual Non-Cumulative Preference Shares, of the AHL PRF Shares. Dividends of $437.50 were declared on the AHL PRF Shares on February 28, 2025, to be paid on or around April 1, 2025.

On November 29, 2024, the Company issued a notice of redemption in connection with all of its issued and outstanding 5.950% Fixed-to-Floating Perpetual Non-Cumulative Preference Shares (the "AHL PRC Shares") (NYSE: AHL PRC). The redemption took place on January 1, 2025, with payment on January 2, 2025, and was conducted pursuant to the terms of the certificate of designation, dated May 2, 2013, governing the AHL PRC Shares. The AHL PRC Shares were subsequently delisted from the NYSE.

During the twelve months ended December 31, 2025, we paid aggregate dividends of $14.1 million, $14.1 million and $17.3 million on our AHL PRD Shares, AHL PRE Shares and AHL PRF Shares, respectively. The terms of our Preference Shares contain restrictions on our ability to pay dividends to holders of our ordinary shares.

In August 2018, Aspen Insurance UK Services Limited, Aspen Insurance U.S. Services Inc. and Aspen Bermuda entered into an Outsourcing Agreement (the "Original IT Outsourcing Agreement") with Cognizant Worldwide Limited, a company registered in England ("Cognizant"). Pursuant to the Original IT Outsourcing Agreement, Cognizant provided the Company with information technology services to enable us to deliver greater operating effectiveness and efficiencies. The Original IT Outsourcing Agreement became effective in August 2018 and had an initial term period of five years beginning in October 2018. The Company had the right to extend the Original IT Outsourcing Agreement for an additional two-year term.

In December 2020, Aspen Insurance UK Services Limited, Aspen Insurance U.S. Services Inc. and Aspen Bermuda entered into a new Outsourcing Agreement (the "IT Outsourcing Agreement") with Cognizant, which replaced and superseded the Original IT Outsourcing Agreement and significantly reduced the information technology services provided thereunder. The IT Outsourcing Agreement became effective in December 2020 and has an initial term of four years. The Company has the right to extend the IT Outsourcing Agreement for an additional two-year term.

In November 2024, the Company signed a new contract with Cognizant for a further three-year term (with an option for an additional two years). The total contract value for the latest agreement for Application Development and Management Services with Cognizant is $16.5 million over three years.

In 2025, the Company paid Cognizant approximately $12.7 million (2024 — $11.6 million, 2023 — $11.5 million) for services rendered under the Original IT Outsourcing Agreement.

The IT Outsourcing Agreement contains customary representations and warranties and indemnity, termination and default provisions. We may terminate the IT Outsourcing Agreement for any reason by providing ninety days' prior written notice. In addition, we may terminate the IT Outsourcing Agreement on shorter notice as a result of, among other things, a material breach if not cured within a specified time, insolvency, persistent breaches, failure to meet key milestones, a material adverse change (as defined in the IT Outsourcing Agreement) occurs in relation to Cognizant or particular circumstances constituting a change in control.

*Business Process Outsourcing Agreement:*

In March 2023, Aspen Insurance UK Services Limited, Aspen Insurance U.S. Services, Inc. and Aspen Bermuda entered into an Amended and Restated Outsourcing Agreement (as amended, the "BPO Outsourcing Agreement") with Genpact (UK) Limited, a company incorporated in England, United Kingdom ("Genpact"). Pursuant to the agreement, Genpact will provide us with a range of operational business processes, primarily from their offshore service center in Gurugram, India, to enable us to deliver greater operating effectiveness and efficiencies. Under the BPO Outsourcing Agreement, Genpact provides a range of operational services across core and support functions, including, but not limited to, Insurance and Reinsurance, Finance, Actuarial and Compliance. The BPO Outsourcing Agreement has minimum service levels that Genpact must meet or exceed.

The BPO Outsourcing Agreement became effective in March 2023 and was amended in January 2024. The BPO Outsourcing Agreement has an initial term period of three years. We have the right to extend the BPO Outsourcing Agreement for three additional one year terms. This agreement extended the relationship with Genpact that was contracted in the 2018 agreement for a five year period.

Under the terms of the BPO Outsourcing Agreement, Genpact will provide support function services to the Company. The compensation structure under the BPO Outsourcing Agreement includes a combination of fixed and variable fees which may fluctuate, as set forth in the BPO Outsourcing Agreement, based on our actual use of Genpact's services. In 2025, the Company paid Genpact $9.6 million (2024 — $12.3 million, 2023 — $10.8 million) for services rendered under the BPO Outsourcing Agreement.

The BPO Outsourcing Agreement contains customary representations and warranties and indemnity, termination and default provisions. We may terminate the BPO Outsourcing Agreement for any reason by providing ninety (90) days' prior written notice. In addition, we may terminate the BPO Outsourcing Agreement as a result of, among other things, a material breach if not cured within a specified time, persistent breaches, insolvency, change of control, failure to meet key milestones or a material adverse change as defined in the BPO Outsourcing Agreement.

*IT Infrastructure Outsourcing Agreement*

In June 2022, Aspen Insurance UK Services Limited entered into a Master Services Agreement: ITO Services (the "IT Infrastructure Outsourcing Agreement") with Mindtree Limited, a company incorporated in India ("LTIMindtree"). Pursuant to the IT Infrastructure Outsourcing Agreement, LTIMindtree will provide us with a range of IT infrastructure and cybersecurity-related services, including, but not limited to, in relation to network services, database service, cybersecurity management and protection and cloud-related services. Such services will be provided primarily from their offshore service center in Bangalore, India, to enable us to deliver greater operating effectiveness and efficiencies.

The IT Infrastructure Outsourcing Agreement became effective in June 2022 and has an initial term period of three years. We have the right to extend the initial term on the IT Infrastructure Outsourcing Agreement by up to two further periods of one year from the expiry of the initial term, by giving written notice to the service provider at least ninety (90) days prior to the expiry of the initial term or an extension period, as applicable.

The IT Infrastructure Outsourcing Agreement has minimum service levels that LTIMindtree must meet or exceed. The compensation structure under the IT Infrastructure Outsourcing Agreement includes a combination of fixed and variable fees which are both applicable and may fluctuate based on our actual use of LTIMindtree's services, as set forth in the IT Infrastructure Outsourcing Agreement. In 2025, the Company paid LTIMindtree $8.2 million, (2024 — $8.3 million, 2023 — $6 million approximately) for services rendered under the IT Infrastructure Outsourcing Agreement.

The IT Infrastructure Outsourcing Agreement contains customary representations and warranties and indemnity, termination and default provisions. We may terminate the IT Infrastructure Outsourcing Agreement for any reason by providing three months' prior written notice and by paying for (i) the services satisfactorily performed and accepted by Aspen up to the effective date of such termination and (ii) any other pre-agreed termination charges ranging from $0 to $750,000, depending on the circumstances. In addition, we may terminate the IT Infrastructure Outsourcing Agreement as a result of, among other things, a material breach if not cured within a specified time, persistent breaches, insolvency, change of control, failure to meet key milestones or material adverse change as defined in the IT Infrastructure Outsourcing Agreement.

*Loss Portfolio Transfer ("LPT") Agreement:*

In January 2022, Aspen Holdings and certain of its subsidiaries entered into an Amended and Restated Reinsurance Agreement with a subsidiary of Enstar, which we refer to as the LPT, which amended and restated the Original Agreement. The transaction successfully closed in May 2022.

Under the terms of the LPT, Enstar's subsidiary will reinsure net losses incurred on or prior to December 31, 2019 on all of the Company's net loss reserves of $3,120.0 million as of September 30, 2021. The LPT provides for a limit of $3,570.0 million in consideration for a premium of $3,160.0 million. The amount of net loss reserves ceded, as well as the premium and limit amounts provided under the LPT, have been adjusted for claims paid between October 1, 2021 and the closing date of the transaction. The premium includes $2,610.1 million of premium previously paid with respect to reserves ceded under the Original Agreement, which will continue to be held in trust accounts to secure the Enstar subsidiary's obligations under the LPT. The incremental new premium will initially be held in funds withheld accounts in their original currencies maintained by the Company but will be released to the trust accounts maintained by the Enstar subsidiary no later than September 30, 2025. The funds withheld by the Company will be credited with interest at an annual rate of 1.75% plus, for periods after October 1, 2022, an additional amount equal to 50% of the amount by which the total return on the Company's investments and cash and cash equivalents exceeds 1.75%. Under the LPT, the Enstar subsidiary has assumed claims control of the subject business, pursuant to the provisions of an administrative services agreement subsequently entered into between the parties in June 2022.

*2026 Term Loan & 2030 Senior Notes*

On July 26, 2023, the Company entered into a $300.0 million term loan facility due November 9, 2026 at a borrowing rate of term SOFR plus an applicable margin (ranging from 1.13% to 1.75% based on the Company's credit ratings and 1.38% as of December 31, 2023) and a SOFR adjustment of 0.10% pursuant to a term loan credit agreement among the Company, the several lenders from time to time party thereto, HSBC Bank Bermuda Limited, as structuring agent, Lloyds Bank Plc, as syndication agent, and Citibank, N.A., as administrative agent (the "2026 Term Loan"). On November 9, 2023, the Company drew down $300.0 million on the 2026 Term Loan and the proceeds were used to redeem the senior notes previously issued by the Company that were due in November 2023.

On June 13, 2025, the Company closed its offering of $300.0 million aggregate principal amount of its 5.750% Senior Notes due 2030 (the "2030 Senior Notes"). The net proceeds from the offering, net of debt issuance costs, were $296.8 million, and the proceeds were used to repay the $300.0 million 2026 Term Loan.

Contemporaneously with the Merger, on February 24, 2026 the Company executed the supplemental indenture and related documentation relating to the outstanding 2030 Senior Notes. For more information regarding the Merger, refer to the "*Explanatory Note*" on page 2 of this report.

&nbsp;&nbsp;&nbsp;&nbsp;D. Change of Ownership of Our Ordinary Shares

Securities may be offered or sold in Bermuda only in compliance with the provisions of the Investment Business Act of 2003 (as amended), and up until November 2025, the Exchange Control Act 1972, and related regulations of Bermuda that regulate the sale of securities in Bermuda. As of November 3, 2025, the Exchange Control Act 1972 was repealed and the Beneficial Ownership Act 2025 was brought into effect, under which the central register of Bermuda companies was transferred from the BMA to the Registrar of Companies ("ROC"). The ROC now handles filing/maintenance of beneficial ownership information and related requirements for most Bermuda companies (including insurers) that are in scope under the Beneficial Ownership Act. While the Exchange Control regime has been repealed, the BMA remains the regulator for insurance companies under the Insurance Act 1978 and therefore any changes in controllers (e.g., shareholders crossing specified thresholds like 10%, 20%, 33%, 50%) require BMA notification or approval under the Insurance Act's change-of-control regime.

&nbsp;&nbsp;&nbsp;&nbsp;**E. Taxation** 

*Bermuda Taxation*

Currently, there is no Bermuda income, corporate or profits tax or withholding tax, capital gains tax or capital transfer tax, estate or inheritance tax payable by holders of our Preference Shares, other than shareholders ordinarily resident in Bermuda, if any. However, on December 27, 2023, Bermuda passed the CIT Act, which became fully operative with respect to the imposition of corporate income tax on January 1, 2025.

Under the CIT Act, Bermuda corporate income tax is chargeable in respect of fiscal years beginning on or after January 1, 2025 and applies only to Bermuda entities that are part of Bermuda Constituent Entity Groups. Where corporate income tax is chargeable to a Bermuda Constituent Entity Group, the amount of corporate income tax chargeable for a fiscal year shall be (1) 15% of the net taxable income of the Bermuda Constituent Entity Group less (2) tax credits applicable to the Bermuda Constituent Entity Group under Part 4 of the CIT Act, or as prescribed. Bermuda will continue to monitor further developments around the world as other jurisdictions address the OECD's standards. The CIT Act includes the ETA and OTLC, which are intended to provide a fair and equitable transition into the new tax regime and have resulted in the recognition of a deferred tax asset of $158.9 million in respect of the ETA and $40.0 million in respect of an OTLC for the twelve months ended December 31, 2024.

Pursuant to the Payroll Tax Act 1995 and the Payroll Tax Rates Act 1995 of Bermuda (together, the "Payroll Tax Act"),an employer is required to pay payroll tax on remuneration paid to each employee, up to a maximum of $1 million (no tax liability accrues on sums above $1 million). Liability for payroll tax is calculated by reference to services provided wholly or mainly in Bermuda during four tax periods, being periods of three months commencing on the first day of April, July, October and January. The meaning of "employee" under the Payroll Tax Act includes deemed employees and covers a broad range of employment structures. Subject to certain express exclusions, "remuneration" is also very broadly defined, to capture any benefit of any kind paid to employees or deemed employees, whether in cash or otherwise. This includes, for example, any gain obtained by the exercise, assignment or release of any option awarded under any option plans. Payroll tax is levied on employers and employees separately, with different marginal rates; however, employers are liable to pay the full amount of payroll tax and are permitted to deduct and remit to the Bermuda Tax Commissioner the amount of the employee's liability from their remuneration.

*United States Taxation* 

The following summary sets forth the material U.S. federal income tax considerations related to the purchase, ownership and disposition of the Company's preference shares, including the preference shares represented by the depositary shares (collectively, the "Preference Shares"). Unless otherwise stated, this summary deals only with shareholders who are U.S. Persons (as defined below) who purchase Preference Shares. The following discussion is only a discussion of the material U.S. federal income tax matters as described herein and does not purport to address all of the U.S. federal income tax consequences that may be relevant to a particular shareholder in light of such shareholder's specific circumstances. In addition, the following summary does not address the U.S. federal income tax consequences that may be relevant to special classes of shareholders, such as financial institutions, insurance companies, regulated investment companies, real estate investment trusts, financial asset securitization investment trusts, dealers or traders in securities or currencies, tax-exempt organizations, U.S. expatriates, partnerships or other pass-through entities (or investors in such entities), persons whose functional currency is not the U.S. dollar, persons subject to any alternative minimum tax, accrual basis taxpayers subject to special tax accounting rules under Section 451(b) of the Code, persons who are 10% U.S. Shareholders (except as specifically addressed below), or persons who hold their shares as part of a hedging or conversion transaction or as part of a short-sale or straddle, who may be subject to special rules or treatment under the Code. This discussion is based upon the Code, the Treasury Regulations promulgated thereunder and any relevant administrative rulings or pronouncements or judicial decisions, all as in effect on the date hereof and as currently interpreted, and does not take into account possible changes in such tax laws or interpretations thereof, which may apply retroactively. This discussion does not include any description of the tax laws of any state or local governments within the United States or of any non-U.S. government. Persons owning or considering making an investment in the Preference Shares should consult their own tax advisors concerning the application of the U.S. federal tax laws to their particular situations as well as any tax consequences arising under the laws of any state, local or foreign taxing jurisdiction prior to making such investment.

If a partnership (or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the Preference Shares, the tax treatment of the partners will generally depend on the status of the partner, the activities of the partnership, and certain determinations made at the partner level. If you are a partner in a partnership owning the Preference Shares you should consult your tax advisor.

For purposes of this discussion, the term "U.S. Person" means a beneficial owner of the Preference Shares that is (i) an individual citizen or resident of the United States, (ii) a corporation created in or organized under the laws of the United States, or organized under the laws of any political subdivision thereof, (iii) an estate the income of which is subject to U.S. federal income taxation regardless of its source, (iv) a trust if either (x) a court within the United States is able to exercise primary supervision over the administration of such trust and one or more U.S. Persons have the authority to control all substantial decisions of such trust or (y) the trust has a valid election in effect to be treated as a U.S. Person for U.S. federal income tax purposes or (v) any other person or entity that is treated for U.S. federal income tax purposes as if it were one of the foregoing.

*Taxation of the Company.* Aspen Holdings and its non-U.S. subsidiaries (other than AUL and Aspen UK) intend to manage their business so that they are not treated as engaged in a trade or business within the United States and thus not subject to U.S. federal income tax on their net income. However, because there is considerable uncertainty as to the activities which constitute being engaged in a trade or business within the United States, we cannot be certain that the IRS will not contend successfully that one or more of these companies is engaged in a trade or business in the United States. If any of these companies is considered to be engaged in a trade or business in the United States during a taxable year, it generally will be subject to U.S. federal income tax (including an additional branch profits tax) on its net income that is treated as effectively connected with the conduct of a U.S. trade or business for such year (except to the extent an applicable income tax treaty provides otherwise), in which case its operating results could be materially adversely affected.

Non-U.S. corporations not engaged in a trade or business within the United States are nonetheless subject to United States income tax imposed by withholding on certain "fixed or determinable annual or periodical gains, profits and income" derived from sources within the United States (such as dividends and certain interest on investments), subject to exemption under the Code or reduction by applicable treaties.

The United States also imposes FET paid to non-U.S. insurers or reinsurers that are not eligible for the benefits of a U.S. income tax treaty that provides for an exemption from the FET with respect to risks (i) of a U.S. entity or individual, located wholly or partially within the United States and (ii) of a non-U.S. entity or individual engaged in a trade or business in the U.S., located within the United States. The rates of tax are 4% for property casualty insurance premiums and 1% for reinsurance premiums.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Treatment of Depositary Shares.* A holder of depositary shares evidenced by depositary receipts generally should be treated for U.S. federal income tax purposes as the owner of such holder's proportionate interest in the Preference Shares held by the depositary (or its custodian) that are represented and evidenced by such depositary receipts and the discussion herein assumes such treatment. Accordingly, any deposit or withdrawal of the Preference Shares by a U.S. Person in exchange for depositary shares generally will not result in the realization of gain or loss to such U.S. Person for U.S. federal income tax purposes.

*Taxation of Distributions*. Subject to the discussions below relating to the potential application of the CFC, RPII and PFIC rules, and the discussion below relating to redemptions of Preference Shares, cash distributions, if any, made with respect to the Preference Shares will constitute dividends for U.S. federal income tax purposes to the extent paid out of current or accumulated earnings and profits of Aspen Holdings (as computed using U.S. tax principles). To the extent such distributions exceed Aspen Holdings' earnings and profits, they will be treated first as a return of the U.S. Person's basis in their shares to the extent thereof, and then as gain from the sale of a capital asset. If, as expected, Aspen Holdings does not compute its earnings and profits under U.S. tax principles, all distributions generally will be treated as dividends for U.S. federal income tax purposes. Dividends paid by us to U.S. Persons who are corporations generally will not be eligible for a dividends received deduction. We believe dividends paid by us on the Preference Shares to non-corporate U.S. Persons should be eligible for reduced rates of taxation as "qualified dividend income" if, as is intended, the Preference Shares remain listed on the NYSE and provided certain requirements, including stock holding period requirements, are satisfied. Qualified dividend income is subject to tax at long-term capital gains rates rather than the higher rates applicable to ordinary income.

Dividends that exceed certain thresholds in relation to a U.S. Person's tax basis in the Preference Shares could be characterized as "extraordinary dividends" under the Code. A non-corporate U.S. Person that receives an extraordinary dividend will be required to treat any losses on the sale of such Preference Shares as long-term capital losses to the extent of the extraordinary dividends such U.S. Person receives that are treated as qualified dividend income.

*Classification of Aspen Holdings or Its Non-U.S. Subsidiaries as CFCs*. Each 10% U.S. Shareholder of a non-U.S. corporation that is a CFC at any time during a taxable year must include in its gross income for U.S. federal income tax purposes its pro rata share of the CFC's subpart F income and tested income (with various adjustments) with respect to any shares that such 10% U.S. Shareholder owns in such non-U.S. corporation (directly or indirectly through certain entities) on the last day in the non-U.S. corporation's taxable year on which it is a CFC, even if the subpart F income or tested income is not distributed. A "10% U.S. Shareholder" generally is a U.S. person that owns (directly, indirectly through non-U.S. entities or by attribution by application of the constructive ownership rules of Section 958(b) of the Code (i.e., "constructively")) at least 10% of the total combined voting power or value of all classes of stock of a non-U.S. corporation. Subpart F income of a CFC generally includes "foreign personal holding company income" (such as interest, dividends and other types of passive income), as well as insurance and reinsurance income (including underwriting and investment income), and tested income is generally any income of the CFC other than subpart F income and certain other categories of income. An entity treated as a non-U.S. corporation for U.S. federal income tax purposes is generally considered a CFC if 10% U.S. Shareholders own (directly, indirectly through non-U.S. entities or constructively), in the aggregate, more than 50% of the total combined voting power of all classes of stock of that non-U.S. corporation or more than 50% of the total value of all stock of that non-U.S. corporation. However, for purposes of taking into account insurance income, these 50% thresholds are generally reduced to 25%. Further, special rules apply for purposes of taking into account any RPII of a non-U.S. corporation, as described below.

Whether Aspen Holdings is a CFC for a taxable year will depend upon facts regarding our direct and indirect shareholders, about which we have limited information. Accordingly, no assurance can be provided that Aspen Holdings will not be a CFC. Further, regardless of whether Aspen Holdings is a CFC, most or all of our non-U.S. subsidiaries are generally treated as CFCs because our U.S. subsidiaries generally are treated as constructively owning the stock of our non-U.S. subsidiaries. Accordingly, any 10% U.S. Shareholders of Aspen Holdings may be required to include in gross income for U.S. federal income tax purposes for each taxable year their pro rata shares of all or a portion of the subpart F and tested income generated by our non-U.S. companies (with various adjustments), regardless of whether any distributions are made to them. Any such 10% U.S. Shareholders should consult their own tax advisors regarding the application of these rules to them.

*The RPII CFC Provisions*. In general, if a non-U.S. corporation is a RPII CFC at any time during a taxable year, a U.S. RPII Shareholder must include in its gross income for U.S. federal income tax purposes its pro rata share of the non-U.S. corporation's RPII with respect to any shares that such U.S. RPII Shareholder owns (directly or indirectly through certain entities) on the last day in the non-U.S. corporation's taxable year, even if the RPII is not distributed. Further, a U.S. RPII Shareholder's pro rata share of any RPII is determined as if all RPII for the taxable year were distributed proportionately only to U.S. RPII Shareholders on that date but generally may not exceed the U.S. RPII Shareholder's pro rata share of the non-U.S. corporation's earnings and profits for the taxable year. In addition, a U.S. RPII Shareholder is required to comply with certain reporting requirements, regardless of the number of shares owned by the U.S. RPII Shareholder.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

For these purposes, a "RPII CFC" is any non-U.S. corporation if, on any day of its taxable year, U.S. RPII Shareholders collectively own (directly, indirectly through non-U.S. entities or constructively) 25% or more of the total combined voting power of all classes of stock of such corporation entitled to vote or 25% or more of the total value of the stock of such corporation. A "U.S. RPII Shareholder" is any U.S. person who owns (directly or indirectly through certain entities) any shares of the non-U.S. corporation. "RPII" is any "insurance income" (as described below) attributable to policies of insurance or reinsurance with respect to which the person (directly or indirectly) insured is a U.S. RPII Shareholder or a "related person" (as defined below) to such U.S. RPII Shareholder. In general, and subject to certain limitations, "insurance income" is income (including premium and investment income) attributable to the issuing of any insurance or reinsurance contract which would be taxed under the portions of the Code relating to insurance companies if the income were the income of a U.S. insurance company. Generally, the term "related person" for this purpose means someone who controls or is controlled by the U.S. RPII Shareholder or someone who is controlled by the same person or persons who control the U.S. RPII Shareholder. Control generally is measured by a greater than 50% ownership interest, applying certain constructive ownership principles. However, the RPII rules generally do not apply with respect to a non-U.S. corporation if either (i) at all times during its taxable year less than 20% of the total combined voting power of all classes of stock of the corporation entitled to vote and less than 20% of the total value of the corporation is owned (directly or indirectly) by persons who are (directly or indirectly) insured under any policy of insurance or reinsurance issued by the corporation or who are related persons to any such person (the "ownership exception"), or (ii) the RPII (determined on a gross basis) of the corporation for the taxable year is less than 20% of its gross insurance income for the taxable year (the "de minimis exception").

We believe that each of our non-U.S. Operating Subsidiaries and Peregrine is a RPII CFC. Nonetheless, we expect that each such company will qualify for one or both of the ownership exception and the de minimis exception in the current taxable year and for the foreseeable future. However, no assurances can be provided that any of our companies will satisfy either exception.

*Computation of RPII*. In order to determine how much RPII, if any, a non-U.S. insurance subsidiary (including for this purpose, Peregrine) has earned in each taxable year, our non-U.S. insurance subsidiaries may obtain and rely upon information from their insureds and reinsureds to determine whether any of the insureds, reinsureds or persons related thereto own (directly or indirectly through certain entities) shares of Aspen Holdings and are U.S. Persons. Aspen Holdings may not be able to determine whether any of the underlying direct or indirect insureds to which our non-U.S. insurance subsidiaries provide insurance or reinsurance are direct or indirect shareholders or related persons to such shareholders. Consequently, Aspen Holdings may not be able to determine accurately the gross amount of RPII earned by each of our non-U.S. insurance subsidiaries in a given taxable year. For any year in which the special RPII CFC inclusion rules apply, Aspen Holdings may also seek information from its shareholders as to whether beneficial owners of the Preference Shares at the end of the year are U.S. Persons so that the RPII may be determined and apportioned among such persons; to the extent Aspen Holdings is unable to determine whether a beneficial owner of the Preference Shares is a U.S. Person, Aspen Holdings may assume that such owner is not a U.S. Person, thereby increasing the per share RPII amount for all known U.S. RPII Shareholders.

*Basis Adjustments*. A U.S. RPII Shareholder's tax basis in its Preference Shares will be increased by the amount of any RPII that the shareholder includes in income. The U.S. RPII Shareholder may exclude from income the amount of any distributions by Aspen Holdings out of previously taxed RPII income. The U.S. RPII Shareholder's tax basis in its Preference Shares will be reduced by the amount of such distributions that are excluded from income.

*Uncertainty as to Application of RPII Provisions.* The RPII provisions have never been interpreted by the courts, and regulations interpreting the RPII provisions exist only in proposed form. It is not certain whether these regulations will be adopted in their proposed form or what changes or clarifications might ultimately be made thereto or whether any such changes, as well as any interpretation or application of the RPII provisions by the IRS, the courts or otherwise, might have retroactive effect. The U.S. Treasury Department has authority to impose, among other things, additional reporting requirements with respect to RPII. Accordingly, the meaning of the RPII provisions and the application thereof to us is uncertain. Further, the applicability of the ownership and de minimis exceptions and the RPII rules more generally depends upon facts regarding our direct and indirect shareholders and insureds, about which we have limited information. Accordingly, no assurances can be provided that any of our companies will satisfy either exception. Moreover, to the extent the exceptions do not apply, we may be unable to correctly determine the amount of RPII that any U.S. RPII Shareholder is required to take into account. Any U.S. Person considering an investment in the Preference Shares should consult their tax advisors as to the effects of these uncertainties.

*Tax-Exempt Shareholders*. A tax-exempt U.S. Person generally will recognize unrelated business taxable income if it is required to include in gross income any of our insurance income under the CFC rules described above (including the RPII provisions). U.S. Persons that are tax-exempt entities are urged to consult their tax advisors as to the potential impact of the unrelated business taxable income provisions of the Code. A tax-exempt organization that is treated as a 10% U.S. Shareholder or a U.S. RPII Shareholder also must file IRS Form 5471 in the circumstances described below.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Redemption of Preference Shares*. A redemption of the Preference Shares will be treated under Section 302 of the Code as a distribution with respect to the Preference Shares, unless the redemption satisfies one of the tests set forth in Section 302(b) of the Code enabling the redemption to be treated as a disposition (as discussed below), subject to the discussion herein relating to the potential application of the CFC, RPII and PFIC rules. Under the relevant Code Section 302(b) tests, the redemption generally will be treated as a sale or exchange only if it (1) is substantially disproportionate, (2) constitutes a complete termination of the holder's stock interest in us or (3) is "not essentially equivalent to a dividend." In determining whether any of these tests are met, shares considered to be owned by the holder by reason of certain constructive ownership rules set forth in the Code, as well as shares actually owned, must generally be taken into account. It may be more difficult for a U.S. Person who owns, actually or constructively by operation of certain attribution rules, any of our other shares to satisfy any of the above requirements. The determination as to whether any of the alternative tests of Section 302(b) of the Code is satisfied with respect to a particular holder of the Preference Shares depends on the facts and circumstances as of the time the determination is made.

*Dispositions of Preference Shares*. Subject to the discussion above relating to redemptions and the discussions below relating to the potential application of Section 1248 of the Code and the PFIC rules, U.S. Persons that hold Preference Shares generally should recognize capital gain or loss for U.S. federal income tax purposes on the sale, exchange, redemption or other disposition of such Preference Shares in the same manner as on the sale, exchange, redemption or other disposition of any other shares held as capital assets. If the holding period for these Preference Shares exceeds one year, under current law any gain will be subject to tax at the rates applicable to long-term capital gain. Moreover, gain, if any, generally will be U.S. source gain and generally will constitute "passive category income" for foreign tax credit limitation purposes.

Section 1248 of the Code provides that if a U.S. Person sells or exchanges stock in a non-U.S. corporation and such person owned, directly, indirectly through certain non-U.S. entities or constructively, 10% or more of the voting power of the corporation at any time during the five-year period ending on the date of disposition when the corporation was a CFC, any gain from the sale or exchange of the shares will be treated as a dividend to the extent of the CFC's earnings and profits (determined under U.S. federal income tax principles) during the period that the shareholder held the shares and while the corporation was a CFC (with certain adjustments). A U.S. Person who owns or owned, directly, indirectly through certain non-U.S. entities or constructively, 10% or more of the voting power of Aspen Holdings may be subject to these rules if Aspen Holdings is or was treated as a CFC.

A 10% U.S. Shareholder may in certain circumstances be required to report a disposition of shares of a CFC by attaching IRS Form 5471 to the U.S. federal income tax or information return that it would normally file for the taxable year in which the disposition occurs. In the event this is determined necessary, Aspen Holdings will provide upon request the relevant information necessary to complete the Form.

Pursuant to the RPII provisions, Section 1248 of the Code also generally applies if a U.S. Person disposes of shares in a RPII CFC (determined without regard to the ownership or de minimis exceptions) that would be taxable as an insurance company under the Code if it were a U.S. corporation, in which case any gain from the disposition generally will be treated as a dividend to the extent of the U.S. Person's share of the corporation's undistributed earnings and profits that were accumulated during the period that the U.S. Person owned the shares (whether or not such earnings and profits are attributable to RPII). In addition, such U.S. Person will be required to comply with certain reporting requirements, regardless of the number of shares owned by the U.S. Person. Existing proposed regulations do not address whether Section 1248 of the Code would apply if a non-U.S. corporation is not an insurance company but the non-U.S. corporation has a subsidiary that is a CFC and that would be taxed as an insurance company if it were a domestic corporation. We believe that these rules should not apply to dispositions of the Preference Shares because Aspen Holdings will not itself be directly engaged in the insurance business. We cannot be certain, however, that the IRS will not interpret the RPII provisions in a contrary manner or that the U.S. Treasury Department will not adopt regulations that provide that these rules will apply to dispositions of Preference Shares. U.S. Persons should consult their tax advisors regarding the effects of these rules on a disposition of Preference Shares.

*Tax on Net Investment Income*. A U.S. Person that is an individual, estate or a trust that does not fall into a special class of trusts that is exempt from such tax will be subject to a 3.8% tax on the lesser of (1) the U.S. Person's "net investment income" (or "undistributed net investment income" in the case of estates and trusts) for the relevant taxable year and (2) the excess of the U.S. Person's modified adjusted gross income for the taxable year over a certain threshold (which in the case of an individual will be between $125,000 and $250,000, depending on the individual's circumstances). A U.S. Person's net investment income will generally include its dividend income and its net gains from the disposition of Preference Shares, unless such dividend income or net gains are derived in the ordinary course of the conduct of a trade or business (other than a trade or business that consists of certain passive or trading activities). Unless a U.S. Person elects otherwise or holds Preference Shares in connection with certain trades or businesses, the CFC and PFIC provisions generally will not apply for purposes of determining a U.S. Person's net investment income with respect to the Preference Shares.

*Passive Foreign Investment Companies.* In general, a non-U.S. corporation will be a PFIC during a given year if (i) 75% or more of its gross income constitutes "passive income" (the "75% test") or (ii) 50% or more of its assets produce (or are held for the production of) passive income (the "50% test"). For these purposes, passive income generally includes interest, dividends, annuities and other investment income. However, the PFIC provisions contain a look-through rule under which a non-U.S. corporation that directly or indirectly owns at least 25% of the value of the stock of another corporation generally is treated, for purposes of determining whether it is a PFIC, as if it received directly its proportionate share of the income, and held its proportionate share of the assets, of the other corporation (the "look-through rule"). As a result, it is expected that the PFIC status of Aspen Holdings should generally depend on the application of the look-through rule to its subsidiaries and whether the income and assets of its subsidiaries will be characterized as passive or active for this purpose. In addition, pursuant to an insurance exception, (a) passive income does not include income that a QIC derives in the active conduct of an insurance business or income of a QDIC, and (b) passive assets do not include assets of a QIC available to satisfy liabilities of the QIC related to its insurance business, if the QIC is engaged in the active conduct of an insurance business, or assets of a QDIC.

Generally, a non-U.S. corporation will be a QIC for a taxable year if it would be taxable as an insurance company if it were a U.S. corporation and its applicable insurance liabilities constitute more than 25% of its total assets for a taxable year. Further, under the 2021 Proposed Regulations, a QIC is in the "active conduct" of an insurance business only if it satisfies either a "factual requirements test" or an "active conduct percentage test." The factual requirements test requires that the officers and employees of the QIC carry out substantial managerial and operational activities on a regular and continuous basis with respect to its core functions (generally its underwriting activities, investment activities, contract and claims management activities and sales activities) and that they perform virtually all of the active decision-making functions relevant to underwriting functions. The active conduct percentage test generally requires that (i) the total costs incurred by the QIC with respect to its officers and employees for services rendered with respect to its core functions (other than investment activities) equal or exceed 50% of the total costs incurred by the QIC with respect to its officers and employees and any other person or entities for services rendered with respect to its core functions (other than investment activities) and (ii) to the extent the QIC outsources any part of its core functions to unrelated entities, officers and employees of the QIC with experience and relevant expertise must select and supervise the person that performs the outsourced functions, establish objectives for performance of the outsourced functions and prescribe rigorous guidelines relating to the outsourced functions which are routinely evaluated and updated. Under certain exceptions, however, a QIC that has no or only a nominal number of employees or that is a vehicle that has the effect of securitizing or collateralizing insurance risks underwritten by other insurance or reinsurance companies or is an insurance linked securities fund that invests in securitization vehicles generally is deemed not engaged in the active conduct of an insurance business. The officers and employees of certain related entities generally may be taken into account for these purposes, provided that the QIC exercises regular oversight and supervision over the services performed by the related entity's officers and employees. The 2021 Proposed Regulations will not be effective unless and until adopted in final form, but taxpayers may rely on them for taxable years beginning after December 31, 2017 if they are consistently followed.

We believe that, based on the implementation of our current business plan and the application of the insurance exception, our non-U.S. insurance subsidiaries should be considered QICs engaged in the active conduct of an insurance business under one or both of the "factual requirements test" or the "active conduct percentage test," our U.S. insurance subsidiaries should be considered QDICs and none of the income or assets of such insurance subsidiaries should be treated as passive. In addition, the income and assets attributable to our non-U.S. subsidiaries that are not insurance subsidiaries are minimal, relative to the income and assets attributable to our other subsidiaries. As a result, based on the application of the look-through rule, we believe that Aspen Holdings should not be characterized as a PFIC for the current year or the foreseeable future. However, because of legal uncertainties with respect to the interpretation of the PFIC rules and whether the 2021 Proposed Regulations will be adopted as final regulations in their current form, and factual uncertainties with respect to our planned operations, there is a risk that Aspen Holdings will be characterized as a PFIC in one or more years.

If Aspen Holdings is characterized as a PFIC for any year during which a U.S. Person holds Preference Shares of Aspen Holdings, it generally will continue to be treated as a PFIC for the years during which such U.S. Person holds such shares unless the U.S. Person has made a "qualified electing fund" election, described below.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

If Aspen Holdings were characterized as a PFIC during a given year, each U.S. Person holding Preference Shares of Aspen Holdings generally would be subject to a penalty tax at the time of the sale at a gain of, or receipt of an "excess distribution" with respect to, their Preference Shares, unless such person is a 10% U.S. Shareholder subject to tax under the CFC rules or such person made a "qualified electing fund" election or "mark-to-market" election (which mark-to-market election would generally require the shareholder to include as ordinary income any appreciation in the value of its shares at the end of a taxable year and allow a shareholder to deduct any depreciation in the value of its shares (up to the amount of prior gain inclusions) at the close of the taxable year). If Aspen Holdings is considered a PFIC for any taxable year and the Preference Shares are treated as "marketable stock" in such year, then a U.S. Person may make a mark-to-market election with respect to its Preference Shares. The Preference Shares will be marketable if they are regularly traded on certain qualifying stock exchanges, including the NYSE. However, there can be no assurance that such election will be available. Additionally, because a mark-to-market election usually cannot be made for any lower-tier PFICs, a U.S. Person will generally continue to be subject to the special tax rules discussed above with respect to its indirect interest in any non-U.S. subsidiary of Aspen Holdings classified as a PFIC. As a result, it is possible that any mark-to-market election with respect to the Preference Shares will be of limited benefit. Further, it is uncertain whether Aspen Holdings would be able to provide its shareholders with the information necessary for a U.S. Person to make a "qualified electing fund" election. In addition, if Aspen Holdings were considered a PFIC, upon the death of any U.S. individual owning Preference Shares, such individual's heirs or estate would not be entitled to a "step-up" in the basis of the Preference Shares that might otherwise be available under U.S. federal income tax laws. In general, a shareholder receives an "excess distribution" if the amount of the distribution is more than 125% of the average distribution with respect to the shares during the three preceding taxable years (or shorter period during which the taxpayer held the shares). In general, the penalty tax is equivalent to the taxes that are deemed due during the period the shareholder owned the shares, computed by assuming that the excess distribution or gain (in the case of a sale) with respect to the shares was earned in equal portions and taxable at the highest applicable tax rate on ordinary income throughout the shareholder's period of ownership, and an interest charge for the failure to pay such taxes for prior periods. The interest charge is equal to the applicable rate imposed on underpayments of U.S. federal income tax for such periods. In addition, a distribution paid by Aspen Holdings to U.S. shareholders that is characterized as a dividend and is not characterized as an excess distribution would not be eligible for reduced rates of tax as qualified dividend income if Aspen Holdings were considered a PFIC in the taxable year in which such dividend is paid or in the preceding taxable year. A U.S. Person that is a shareholder in a PFIC may also be subject to additional information reporting requirements, including the filing of an IRS Form 8621.

U.S. investors are urged to consult with their tax advisors and to consider making a "protective" QEF election with respect to the Preference Shares to preserve the possibility of making a retroactive QEF election. A U.S. Person that makes a QEF election with respect to a PFIC is currently taxable on its pro rata share of the ordinary earnings and net capital gain of such company during the years it is a PFIC (at ordinary income and capital gain rates, respectively), regardless of whether or not distributions were received. In addition, any of the PFIC's losses for a taxable year will not be available to U.S. Persons and may not be carried back or forward in computing the PFIC's ordinary earnings and net capital gain in other taxable years. A U.S. Person generally increases the basis of its PFIC shares, and the basis of any other property of the U.S. Person by reason of which such U.S. Person is considered to indirectly own PFIC shares, by amounts included in such U.S. Person's gross income pursuant to the QEF election. Therefore, an electing U.S. Person will generally increase the basis of its Preference Shares by amounts included in the U.S. Person's gross income pursuant to the QEF election. Distributions of income that had previously been taxed pursuant to the QEF election will result in a corresponding reduction of basis in the Preference Shares and will not be taxed again as a distribution to the U.S. Person. A U.S. Person holding Preference Shares will generally be required to file an IRS Form 8621 (which is a form that is required to be filed by holders of equity in a PFIC) for each tax year that it holds Preference Shares and we are characterized as a PFIC, regardless of whether such U.S. Person has a QEF election in effect or receives an excess distribution.

If Aspen Holdings is a PFIC for any taxable year, a U.S. Person who holds the Preference Shares would be treated as owning a proportionate amount of the shares of any PFICs in which Aspen Holdings directly, or in certain cases indirectly, owns an interest, and the PFIC rules described above generally would apply with respect to the U.S. Person's indirect ownership of such PFICs.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Foreign Tax Credit.* If U.S. Persons own a majority of our shares, only a portion of the current income inclusions, if any, under the CFC, RPII and PFIC rules and of dividends paid by us (including any gain from the sale of shares that is treated as a dividend under Section 1248 of the Code) will be treated as foreign source income for purposes of computing a shareholder's U.S. foreign tax credit limitations. We will consider providing shareholders with information regarding the portion of such amounts constituting foreign source income to the extent such information is reasonably available. It is also likely that substantially all of the "subpart F income," RPII and dividends that are foreign source income will constitute "passive category income" for foreign tax credit limitation purposes. Additionally, tested income will constitute a separate basket for foreign tax credit purposes. There are also significant and complex limits on a U.S. Person's ability to claim foreign tax credits, and recently issued U.S. Treasury Regulations that apply to foreign income taxes paid or accrued in taxable years beginning on or after December 28, 2021 restrict the availability of foreign tax credits based on the nature of the tax imposed by the foreign jurisdiction. Through subsequently issued guidance, the IRS suspended the application of these rules for periods beginning on or after December 28, 2021, and ending on or before December 31, 2023 (the "relief period"), and subsequently further extended such relief until the publication of a notice or other guidance suspending the relief period. Thus, it may not be possible for most shareholders to utilize excess foreign tax credits to reduce U.S. tax on such income. The rules relating to the determination of the U.S. foreign tax credit are complex, and U.S. Persons should consult their tax advisors regarding the availability of a foreign tax credit in their particular circumstances and the possibility of claiming an itemized deduction (in lieu of the foreign tax credit) for any foreign taxes paid or accrued.

*Information Reporting and Backup Withholding*. Information returns may be filed with the IRS in connection with distributions on our Preference Shares and the proceeds from a sale or other disposition of the Preference Shares unless the holder of the Preference Shares establishes an exemption from the information reporting rules. A holder of the Preference Shares that does not establish such an exemption may be subject to U.S. backup withholding tax on these payments if the holder is not a corporation or other exempt recipient or fails to provide its taxpayer identification number or otherwise comply with the backup withholding rules. The amount of any backup withholding from a payment to a U.S. Person will be allowed as a credit against the U.S. Person's U.S. federal income tax liability and may entitle the U.S. Person to a refund, provided that the required information is furnished to the IRS.

Under certain circumstances, U.S. Persons owning stock in a non-U.S. corporation are required to file IRS Form 5471 with their U.S. federal income tax returns. Generally, information reporting on IRS Form 5471 is required by (i) a person who is treated as a U.S. RPII Shareholder, (ii) a 10% U.S. Shareholder of a non-U.S. corporation that is a CFC at any time during the taxable year and who owned the stock on the last day of that year on which it was a CFC and (iii) under certain circumstances, a U.S. Person who acquires stock in a non-U.S. corporation and as a result thereof owns 10% or more of the voting power or value of such non-U.S. corporation, whether or not such non-U.S. corporation is a CFC. Aspen Holdings will, upon request, provide to all U.S. Persons registered as shareholders of its Preference Shares the relevant information necessary to complete Form 5471 in the event Aspen Holdings determines this is necessary.

Certain U.S. Persons who are individuals may be required to report information relating to an interest in the Preference Shares on IRS Form 8938, subject to certain exceptions (including an exception for Preference Shares held in accounts maintained by certain financial institutions).

U.S. Persons who own directly or indirectly more than 50% of the voting power or the total value of our shares should consider their possible obligation to file FinCEN Form 114, Report of Foreign Bank and Financial Accounts, with respect to our financial accounts. Additionally, such U.S. Persons should consider their possible obligations to annually report certain information with respect to the Form with their U.S. federal income tax returns.

U.S. Persons who fail to report the required information could be subject to substantial penalties, and, in such circumstances, the statute of limitations for assessment of tax could be suspended, in whole or part. U.S. Persons should consult their tax advisors regarding the potential application of these and any other applicable information reporting requirements, including the IRS Form 8621 filing requirements described above, that may apply to their purchase, ownership or disposition of Preference Shares.

*Possible Changes in U.S. Tax Law*. On August 16, 2022, the U.S. government enacted the IRA. The IRA contains a number of tax-related provisions, including a 15% minimum corporate income tax on certain large corporations as well as an excise tax on stock repurchases. The impact of the IRA on our financial position will depend on the facts and circumstances each year. Further, it is possible that other legislation that may be introduced and enacted by the current Congress or future Congresses, could have an adverse impact on us or holders of Preference Shares. Any such legislation could have a retroactive effect.

Additionally, the U.S. federal income tax laws and interpretations regarding whether a company is engaged in a trade or business within the United States or is a PFIC, or whether U.S. Persons would be required to include in their gross income the "subpart F income," "tested income" or RPII of a CFC, are subject to change, possibly on a retroactive basis. Certain of the regulations regarding the application of the PFIC rules to insurance companies and the regulations regarding RPII are still in proposed form. New regulations or pronouncements interpreting or clarifying such rules may be forthcoming. We cannot be certain if, when or in what form such regulations or pronouncements may be provided and whether such guidance will have a retroactive effect.

*E.U. Taxation*

*Common Reporting Standard*. The Common Reporting Standard ("CRS") has been introduced as an initiative by the OECD and is imposed on members of the European Union by the European Directive on Administrative Co-operation. Similar to the legislation commonly known as the Foreign Account Tax Compliance Act introduced by the United States, the CRS requires financial institutions which are subject to the rules to report certain financial information in respect of account holders. The CRS became effective as of January 1, 2016 and E.U. member states generally began to exchange the required information pursuant to the CRS from the end of September 2017 onwards. We intend to operate in compliance with CRS.

**Item 11.&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Quantitative and Qualitative Disclosures about Market Risk** 

We believe we are principally exposed to three types of market risk: interest rate risk, foreign currency risk and credit risk.

*Interest rate risk*. Our investment portfolio consists primarily of fixed income securities. Fluctuations in interest rates have a direct impact on the market valuation of these securities. Accordingly, our primary market risk exposure is to changes in interest rates. As interest rates rise, the market value of our fixed-income portfolio falls and the converse is also true. We manage interest rate risk by maintaining a short to medium duration to reduce the effect of interest rate changes on book value.

The table below depicts interest rate change scenarios and the effect on our interest rate sensitive invested assets as at December 31, 2025:

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Foreign currency risk.* Our reporting and the functional currency of our operations is the U.S. Dollar. As at December 31, 2025, approximately 86.7% of our cash and investments was held in U.S. Dollars (2024 — 89.2%), and approximately 13.3% was in currencies other than the U.S. Dollar (2024 — 10.8%).

For the twelve months ended December 31, 2025, 24.9% of our gross premiums were written in currencies other than the U.S. Dollar (2024 — 25.2%) and we expect that a similar proportion will be written in currencies other than the U.S. Dollar in 2026.

Other foreign currency amounts are remeasured to U.S. Dollars and the resulting foreign exchange gains or losses are reflected in the statement of operations. The remeasurement is calculated using current exchange rates for the balance sheets and average exchange rates for the statement of operations. We may experience exchange losses to the extent that our foreign currency exposure is not properly managed or otherwise hedged which would in turn adversely affect our results of operations and financial condition. Management estimates that a 10% change in the exchange rate between British Pounds and U.S. Dollars, as an example, as at December 31, 2025 would have impacted reported net comprehensive income by approximately $29.3 million (2024 — $11.9 million).

We use foreign currency forward exchange contracts to assist in matching our liabilities under insurance and reinsurance policies that are payable in foreign currencies with investments that are denominated in those currencies. A foreign exchange contract involves an obligation to purchase or sell a specified currency at a future date at a price set at the time of the contract. Foreign exchange contracts will not eliminate fluctuations in the value of our assets and liabilities denominated in foreign currencies but rather allow us to establish a rate of exchange for a future point in time.

As at December 31, 2025, we held foreign exchange contracts that were not designated as hedges under ASC 815, *"Derivatives and Hedging"* with an aggregate notional value of $1,404.0 million (2024 — $1,586.9 million). The foreign exchange contracts are recorded as derivative assets or derivative liabilities in the balance sheet with changes recorded as a change in fair value of derivatives in the statement of operations. For the twelve months ended December 31, 2025, the impact of foreign exchange contracts on net income was a gain of $43.9 million (December 31, 2024 — loss of $34.0 million).

As at December 31, 2025, we held foreign exchange contracts that were designated as cash flow hedges under ASC 815 with an aggregate notional value of $186.8 million (2024 — $158.0 million). The foreign exchange contracts are recorded as derivative assets or derivative liabilities in the consolidated balance sheet with the changes in fair value recorded in other comprehensive income. For the twelve months ended December 31, 2025, we recognized a gain of $6.7 million (December 31, 2024 — loss of $6.5 million) in other comprehensive income.

As the foreign exchange contracts settle, the realized gain or loss is reclassified from other comprehensive income into general, administration and corporate expenses in the statement of operations and other comprehensive income. For the twelve months ended December 31, 2025, the amount recognized within general, administration and corporate expenses for settled foreign exchange contracts was a realized gain of $0.7 million (December 31, 2024 — loss of $0.9 million).

*Embedded derivative on loss portfolio contract.* The loss portfolio transfer contract includes a funds withheld arrangement that provides returns to the reinsurer based on Aspen's investment performance, guaranteeing a minimum of 1.75% return. Such funds withheld arrangements are examples of embedded derivatives and therefore this instrument is accounted for as an option-based derivative. For the twelve months ended December 31, 2025, the amount recognized as a change in fair value of derivatives in the consolidated statement of operations was a gain of $2.9 million (December 31, 2024 —gain of $12.9 million).

*Credit risk.* We have exposure to credit risk primarily as a holder of fixed income securities and private securities. Our risk management strategy and investment policy is to invest mainly in debt instruments of high credit quality issuers. We also invest a portion of the portfolio in securities that are below investment grade or in unrated private securities and other specialty asset classes. We reduce the amount of credit exposure by setting limits with respect to particular ratings categories, business sectors and any one issuer. As at December 31, 2025, the average rating of fixed income securities in our investment portfolio was "AA-" (December 31, 2024 — "AA-").

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

In addition, we are exposed to the credit risk of our insurance and reinsurance brokers to whom we make claims payments for our policyholders, as well as to the credit risk of our reinsurers and retrocessionaires who assume business from us. Other than fully collateralized reinsurance, the substantial majority of our reinsurers have a rating of "A" (Excellent), the third highest of fifteen rating levels, or better by A.M. Best and the minimum rating of any of our material reinsurers is "A-" (Excellent), the fourth highest of fifteen rating levels, by A.M. Best. At December 31, 2025, the total amount recoverable by the Company from reinsurers was $4,281.9 million (December 31, 2024 — $4,172.0 million. Of the Company's reinsurance recoverable balance at December 31, 2025, 61.9% is collateralized by our reinsurers, 37.3% is recoverable from reinsurers rated A- or higher by major rating agencies and 0.8% is recoverable from reinsurers rated lower than A- by major rating agencies (December 31, 2024 — 55.9%, 44.0% and 0.1%, respectively). As at December 31, 2025, the Company's largest uncollateralized exposures to individual reinsurers represent 17.2% (December 31, 2024 — 15.4%), 15.1% (December 31, 2024 — 11.5%), and 7.6% (December 31, 2024 — 8.8%). As at December 31, 2025, the Company recognized an allowance for expected credit losses of $16.2 million (December 31, 2024 — $27.5 million) for reinsurance recoverables from reinsurers.

The Company maintains disclosure controls and procedures (as that term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), that are designed to ensure that information required to be disclosed in the Company's reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to the Company's management, including its Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosures. The Company, under the supervision and with the participation of the Company's management, including the Company's Chief Executive Officer and Chief Financial Officer, has evaluated the design and operation of the Company's disclosure controls and procedures as of December 31, 2025. Based on that evaluation, the Company's Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2025, the Company's disclosure controls and procedures were not effective, solely due to the material weakness described below.

&nbsp;&nbsp;&nbsp;&nbsp;**B. Management's Annual Report on Internal Control over Financial Reporting** 

Management is responsible for establishing and maintaining adequate internal control over financial reporting as defined in Exchange Act Rule 13a-15(f) and as contemplated by Section 404 of the Sarbanes-Oxley Act.

Our internal control system was designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with U.S. generally accepted accounting principles.

Our management does not expect that our disclosure controls will prevent all errors and all fraud. A control system, no matter how well designed and operated, has inherent limitations and can provide only reasonable, not absolute, assurance that the objectives of the control system are met.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements or omissions. Also, our evaluation of effectiveness is as of a particular point in time and projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

*Material Weakness in Internal Control Over Financial Reporting*

In the course of assessing the effectiveness of the Company's internal control over financial reporting as of December 31, 2025, management identified a material weakness in the design and operating effectiveness of existing internal controls within its process level controls over its Claims function. The material weakness was a result of deficiencies in the design and operation of transaction-level internal controls over the input of financial and non-financial claims data.

In making this assessment, management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO") in Internal Control - Integrated Framework (2013). Based on this assessment, our management has concluded that our internal control over financial reporting was not effective as of December 31, 2025 due to the material weaknesses described above.

The Company is committed to addressing the material weakness and has begun to implement changes designed to improve its internal controls over financial reporting and to remediate the material weakness, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Redesigning transaction-level claims processing controls, including the enhancement of inspectable evidence associated with the operation of controls.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Redesigning controls to test the completeness and accuracy of financial and non-financial claims data.

As the Company evaluates and enhances its internal control over financial reporting, it may take additional measures to modify, or add to, the remediation measures described above.

Our Board and Audit Committee are committed to, and will continue to monitor the testing progress and effectiveness of our management's implemented control-remediation activities.

&nbsp;&nbsp;&nbsp;&nbsp;**C. Attestation report of the registered public accounting firm**

The Company's independent registered public accounting firm, Ernst & Young Ltd., has issued an attestation report on management's assessment of the Company's internal control over financial reporting as of December 31, 2025 as stated in their report appearing in "*Report of Independent Registered Public Accounting Firm*" included in "Item 18. Financial Statements."

&nbsp;&nbsp;&nbsp;&nbsp;**D. Changes in Internal Control Over Financial Reporting** 

Other than the changes described in Item 15.B.,there have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f)) that have occurred during the year ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

_____________

(1)&nbsp;&nbsp;&nbsp;&nbsp;Audit fees consist of fees paid to EY for professional services for the audit of the Company's annual consolidated financial statements, review of quarterly consolidated financial statements, audit of annual statutory statements, and for services that are normally provided by independent auditors in connection with statutory, SEC and regulatory filings or engagements (including comfort letters and consents).

(2)&nbsp;&nbsp;&nbsp;&nbsp;Audit-related fees consist of fees paid for assurance and related services for the performance of the audit or review of the Company's financial statements (other than the audit fees disclosed above), such as the audit of Solvency II balance sheet and Lloyd's regulatory filings.

(3)&nbsp;&nbsp;&nbsp;&nbsp;All other fees totaling $96,200 relate to fees billed to the Company by EY for non-audit services rendered to the Company in connection with Canadian Actuarial Support.

The policy of the Audit Committee is to approve all audit and permissible non-audit services to be provided by the independent registered public accounting firm during the year. The Audit Committee considered whether the provision of the non-audit services by EY was compatible with maintaining EY's independence with respect to the Company and determined that the provision of such services was compatible with EY maintaining its independence. The Audit Committee approved all of the services provided by EY for the fiscal year ended December 31, 2025.

**Item 16D.&nbsp;&nbsp;&nbsp;&nbsp;Exemptions from the Listing Standards for Audit Committee**

**Item 16E.&nbsp;&nbsp;&nbsp;&nbsp;Purchases of Equity Securities by the Issuer and Affiliated Purchasers**

None.

**Item 16F.&nbsp;&nbsp;&nbsp;&nbsp;Change in Registrant's Certifying Accountant**

With effect from June 10, 2024, upon the recommendation of the Company's Audit Committee and Board, and following receipt of regulatory approvals and completion of internal governance procedures, the Company has appointed Ernst & Young Ltd. ("EY Bermuda") as its independent registered public accounting firm beginning with the fiscal year ending December 31, 2024. The Company's incumbent independent registered public account firm, Ernst & Young LLP ("EY London"), has accordingly resigned from such position, with effect from June 21, 2024.

EY London's reports on the Company's financial statements for the years ended December 31, 2022 and 2023 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles.

During the Company's fiscal years ended December 31, 2022 and 2023, and the subsequent interim periods through EY London's resignation, there were: (i) no disagreements between the Company and EY London on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to EY London's satisfaction, would have caused EY London to make reference thereto in its reports; and (ii) no "reportable events" described in Item 16F(a)(1)(v) of Form 20-F.

The Company provided EY London with a copy of the foregoing disclosure and received from EY London a letter addressed to the SEC stating whether it agrees with such disclosure. A copy of EY London' letter, filed with the SEC on July 12, 2024, is referenced as Exhibit 15.3.

**Item 16G.&nbsp;&nbsp;&nbsp;&nbsp;Corporate Governance**

As a foreign private issuer, we are entitled to follow the practice of our home country, Bermuda, with respect to certain corporate governance requirements, rather than adhering to the corporate governance requirements that are applicable to U.S. issuers listed on the NYSE. Additionally, following the effective time of the Merger, because 100% of our Ordinary Shares are owned by Sompo and are not listed on the NYSE, we are a "controlled company" within the meaning of NYSE corporate governance standards. Controlled companies are also exempt from certain NYSE corporate governance standards.

Pursuant to Section 303.A.11 of the NYSE Listed Company Manual and Item 16G of Form 20-F, we are required to list the significant differences between our corporate governance practices and the NYSE corporate governance standards applicable to U.S. issuers listed on the NYSE. Listed below are the significant differences:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our Board is not currently composed of a majority of independent directors. The NYSE requires U.S. issuer listed companies to have a board of directors of at least a majority of independent directors. Controlled companies, however, are exempt from this requirement. Under Bermuda law and our Bye-Laws, we are not required to have a majority of independent directors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Following the Merger and changes made subsequently to the Board and its committees, we do not, as at the date of this report, have a nominating/corporate governance committee of the Board. Instead, the functions typically performed by such a committee are performed by the Board. The NYSE requires U.S. issuer listed companies to have a nominating/corporate governance committee composed entirely of independent directors and a committee charter detailing the committee's purpose and responsibilities and an annual performance evaluation of the committee. Controlled companies, however, are exempt from this requirement. Under Bermuda law and our Bye-Laws, we are not required to have a nominating or corporate governance committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Following the Merger and changes made subsequently to the Board and its committees, we do not, as at the date of this report, have a compensation committee of the Board. The NYSE requires U.S. issuer listed companies to have a compensation committee composed entirely of independent directors and a committee charter detailing the committee's purpose and responsibilities, an annual performance evaluation of the committee and the rights and responsibilities of the committee with respect to retaining or obtaining advice from an independent adviser. Controlled companies, however, are exempt from this requirement. Under Bermuda law and our Bye-Laws, we are not required to have a compensation committee.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Following the Merger and changes made subsequently to the Board and its committees, we do not, as at the date of this report, have an audit committee of the Board composed of a minimum of three individuals. The NYSE requires U.S. issuer listed companies to have an audit committee that has a minimum of three members. Foreign private issuers are exempt from this requirement. Under Bermuda law and our Bye-Laws, there is no requirement for a fixed number of members for an audit committee. Our Audit Committee is composed of two members, as described further herein.

**Item 16H.&nbsp;&nbsp;&nbsp;&nbsp;Mine Safety Disclosure**

Not applicable.

**Item 16I.&nbsp;&nbsp;&nbsp;&nbsp;Disclosure Regarding Foreign Jurisdictions that Prevent Inspections**

Not applicable.

**Item 16J.&nbsp;&nbsp;&nbsp;&nbsp;Insider Trading Policies**

In 2025, the Company adopted revised insider trading policies and procedures governing the purchase, sale, and other dispositions of the Company's securities by directors, senior management, and employees that are reasonably designed to promote compliance with applicable insider trading laws, rules and regulations, and any listing standards applicable to the Company. A copy of our framework is filed as Exhibit 11.1.

**Item 16K.&nbsp;&nbsp;&nbsp;&nbsp;Cybersecurity**

We maintain an enterprise-wide information security and cyber risk management framework ("Framework") that is designed to protect our information, assets and systems and comply with applicable data security and privacy laws and regulations, in all jurisdictions in which we operate. Our Information Security and Cyber Risk Management Policy is aligned with the National Institute of Standards and Technology ("NIST") cybersecurity framework and sets out our internal framework to enable a consistent and coordinated approach to ensure that information security risks are adequately addressed in a manner proportionate to the nature, scale and complexity of our operations. Our framework is designed to protect information from the time it is created, through its useful life, to its ultimate authorized disposal.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u><u>[Contents](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Our cybersecurity program is designed to provide reasonable assurance that we will have efficient and effective operations; safeguard our assets; produce reliable reporting; comply with applicable laws and regulations; and to identify, protect, detect and respond to, and manage, reasonably foreseeable cybersecurity risks and threats. Our Framework is a key part of our internal control system and uses risk management processes to enable informed and prioritized decisions regarding information and cybersecurity.

Effective identification of information security and cyber risk enable us to focus and prioritize risk management efforts and determine resources required to manage the risks. We regularly assess risks from cybersecurity and technology threats and monitor our information systems for potential vulnerabilities and incidents. Risk identification processes span the entity, segment, function, and operational levels, to capture key risks within business processes, group-wide risks that are not directly associated with an individual function or process, and changes that could impact the internal control environment. Risk assessment involves a dynamic and iterative process for analyzing information security and cyber risks in order to form the basis for classifying information assets according to their value, sensitivity, and criticality; and for determining how risks should be managed, in accordance with our risk tolerance. Our risk assessment considers threats, vulnerabilities, exploitability, likelihood, and magnitude of impact to our operations, assets, individuals and facilities. Risk assessments also consider risk from external parties, including contractors who operate systems on our behalf, individuals who access our systems or data, service providers, and outsourcing entities. Risk assessments play an important role in the control selection processes. As internal and external circumstances change over time, risk identification also captures emerging information security and cyber risks. These and other emerging risks are reported to the Risk Committee of the Board.

Identified risks are recorded in the Group risk register and categorized, using the NIST security control family taxonomy to categorize and aggregate risk information. Once identified, all key information security and cyber risks are assessed to form the basis for determining how risks should be managed. After information security and cyber controls are implemented, they are regularly monitored and evaluated to determine whether the controls are implemented correctly, operate as intended, produce the desired outcome, and continue to comply with laws, regulations and contractual requirements. Monitoring helps to maintain a dynamic understanding of the Group's risk profile and identify control deficiencies which require remediation actions.

As part of our risk management process, we conduct application security assessments, vulnerability management, penetration testing, employee phishing testing, security audits, and ongoing risk assessments. We also maintain a variety of incident response plans that are utilized when incidents are detected. We require employees with access to information systems, including all employees, to undertake data protection and cybersecurity training and compliance programs annually.

Where possible, with respect to our cyber risk management processes, controls are implemented with a corresponding performance scale which is used as the basis for establishing monitoring via Key Risk Indicators ("KRIs"). KRIs are measured against the acceptable level of variance in performance relative to the achievement of control objectives and indicate whether controls are adequately addressing risk and whether risks are changing over time. KRIs that fall outside of pre-established thresholds trigger a more thorough management review and assessment, and where appropriate, any necessary adjustments to controls. Control deficiencies that result in exposures that exceed tolerance will be subject to a monitored mitigation plan with an agreed timeline to reduce residual risk to within the tolerance; and included in risk reporting. In such a case, the risk is implicitly temporarily accepted while mitigation actions progress. The development and ownership of an appropriate response is determined by relevant first line stakeholders in consultation with the Group Chief Information Security Officer ("CISO"). The action plan should be proportionate to the level of exposure and include defined actions aligned to the underlying causes.

In some cases, it might be determined that the exposure exceeds risk tolerance and cannot be brought within acceptable levels through any combination of mitigation or risk transfer. In this case, the applicable business function owner will consult with the CISO to determine the best course of action (e.g., through risk avoidance, an exception process, or increased security requirements for the relevant system/process). Exceptions and risk avoidance circumstances should be rare and will be recorded and reported to the Group Executive Committee. Notably, risk avoidance is not the same as ignoring a risk. See "*Risk Factors - A failure in our data security and/or technology systems or infrastructure or those of third parties, including those caused by security breaches or cyber-attacks could disrupt our business, damage our reputation and cause losses*."

In the normal course, we engage assessors, consultants and other third parties to assist in various cyber-related matters. These engagements cover a range of risk mitigation activities such as threat detection, penetration testing and red/purple team cyber-attack simulations.

We have implemented processes to identify and manage risks from cybersecurity threats associated with our use of such third-party service providers, including in relation to information security, particularly for personal information. These controls include contractual requirements to meet certain information security and testing requirements, alongside ongoing oversight procedures.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u><u>[Contents](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Management has responsibility to manage risk and bring to the Board's attention the most material near-term and long-term risks to the Company. The Company's CISO leads management's assessment and management of cybersecurity risk and is responsible for defining the Framework, and for establishing and maintaining security policies, standards and guidelines for group-wide applicability. Our Company CISO has extensive experience in IT and cybersecurity in particular, spanning over 20+ years within multiple industries including but not limited to financial services. As of December 31, 2025 and through to the Merger, the CISO reports to the Chief Information Officer, who report to the Group Chief Operating Officer, who in turn reports directly to the Company's Group Chief Executive Officer.

Prior to the closing of the Merger, the Board delegated certain of its responsibilities related to the Group's cybersecurity program to the Risk Committee, which, on behalf of the Board, reviews at least once annually, the Group's cybersecurity program, its effectiveness, and related exposures and risks, including actions underway or planned to reduce these risks. This review and oversight may generally encompass data breach risk; cyber prevention and detection controls; privacy matters; incident response plan; third-party cyber risk; cyber trends and events; and other cyber topics determined jointly by management and the Risk Committee. In carrying out this role, the Risk Committee takes into account the relevant work of the CISO. A presentation on cybersecurity matters is made to the Risk Committee at least once annually, and the Board receives updates on operational risks, including cybersecurity matters, at its regular quarterly meetings from the Group Chief Operating Officer, alongside second-line oversight updates from the Group Chief Risk Officer and the Risk Committee. The Internal Audit function also provides third-line oversight of cyber risk elements through periodic testing of our cyber procedures, the results of which are reported to the Risk Committee and subsidiary boards of directors as appropriate.

On the recommendation of the Risk Committee, the Board considers the Group Information Security and Risk Management Policy on an annual basis and oversees our annual enterprise risk assessment on at least an annual basis to assess key risks within the business, including security and technology risks and cybersecurity threats. As a result of the closing of the Merger, certain of the Board's committees, including the Risk Committee, were discontinued, and the full Board assumed the responsibilities previously delegated to the Risk Committee.

For further information regarding the Company's cybersecurity framework and associated governance procedures, please refer to Item 4, "*Business Overview - Certain Regulatory Considerations - Privacy & Cybersecurity Laws*."

For further information on our risk management strategy, refer to Item 4, "*Business Overview - Risk Management - Risk Management Strategy*."

**ASPEN INSURANCE HOLDINGS LIMITED**

**NOTES TO THE AUDITED CONSOLIDATED FINANCIAL STATEMENTS**

**For The Twelve Months Ended December 31, 2025, 2024 and 2023** 

**($ in millions, except share and per share amounts)** 

**1.&nbsp;&nbsp;&nbsp;&nbsp;History, Organization and Business Combination**

Aspen Insurance Holdings Limited ("Aspen Holdings") was incorporated as a Bermuda exempted company on May 23, 2002 as a holding company headquartered in Bermuda. We underwrite specialty insurance and reinsurance on a global basis through our Operating Subsidiaries (as defined below) based in Bermuda, the United States and the United Kingdom: Aspen Bermuda Limited ("Aspen Bermuda"), Aspen Specialty Insurance Company ("Aspen Specialty"), Aspen American Insurance Company ("AAIC"), Aspen Insurance UK Limited ("Aspen UK") and Aspen Underwriting Limited ("AUL") (as the sole corporate member of our Lloyd's operations, Syndicate 4711, which is managed by Aspen Managing Agency Limited ("AMAL") (together, "Aspen Lloyd's")), each referred to herein as an "Operating Subsidiary" and collectively referred to as the "Operating Subsidiaries", as well as through branch operations in Canada, Singapore and Switzerland. We established Aspen Capital Management, Ltd. ("ACML") and other related entities (collectively, "ACM") to leverage our existing underwriting franchise, increase our operational flexibility and provide third-party investors direct access to our capital markets and underwriting expertise. References to the "Company," the "Group," "we," "us" or "our" refer to Aspen Holdings or Aspen Holdings and its consolidated subsidiaries.

From February 2019 until May 2025, the Company was a wholly-owned subsidiary of Highlands Bermuda Holdco, Ltd., which held all of the Company's issued and outstanding Class A ordinary shares, par value $0.001 per share (the "Ordinary Shares") and is an affiliate of certain investment funds managed by affiliates of Apollo Global Management, Inc., a leading global investment manager (collectively with its subsidiaries, "Apollo"). Immediately prior to the Company's initial public offering in May 2025 ("IPO"), Highlands Bermuda Holdco, Ltd. distributed all of the Company's issued and outstanding Ordinary Shares to AP Highlands Holdings, L.P., a Cayman exempted limited partnership, and AP Highlands Co-Invest, L.P., a Cayman exempted limited partnership (together, the "Apollo Shareholders"), as well as certain other individuals. The Apollo Shareholders are each an affiliate of certain investment funds managed by affiliates of Apollo.

In May 2025, the Company completed its IPO of 13,250,000 of its Ordinary Shares. The Ordinary Shares began trading on the New York Stock Exchange ("NYSE") on May 8, 2025. Subsequent to the closing of the IPO, the underwriters exercised in full the option to purchase up to an additional 1,987,500 of the Company's Ordinary Shares. The shares sold in the IPO were sold by the Apollo Shareholders, and the Company did not receive any of the proceeds from the sale of the Ordinary Shares by the Apollo Shareholders. Following the completion of these matters, the Apollo Shareholders collectively beneficially own approximately 82.1% of the Company's Ordinary Shares.

On August 27, 2025, Aspen Insurance Holdings Limited ("Aspen") entered into a definitive Agreement and Plan of Merger (the "Merger Agreement") under which Aspen was to be acquired by a wholly owned indirect subsidiary of Sompo Holdings, Inc. ("Sompo"), a leading global provider of commercial and consumer property and casualty (re)insurance.

The Merger Agreement is by and among Aspen, Endurance Specialty Insurance Ltd., a Bermuda exempted company limited by shares and a wholly-owned indirect subsidiary of Sompo ("Parent"), and Ajax Ltd., a Bermuda exempted company limited by shares and a wholly owned subsidiary of Parent ("Merger Sub"). On February 24, 2026 (the "Effective Time"), Merger Sub merged with and into Aspen, with Aspen surviving such merger (the "Merger", and such surviving company, the "Surviving Company") as a wholly-owned subsidiary of Parent and indirect subsidiary of Sompo.

As from the Effective Time, the issued Class A Ordinary Shares, par value $0.001, of Aspen were automatically converted into the right to receive an amount in cash equal to US$37.50 per share, without interest. In addition, each issued (a) 5.625% Perpetual Non-Cumulative Preference Share (the "5.625% PRD Preference Shares"), (b) Depositary Share, each representing a 1/1000th interest in a share of 5.625% Perpetual Non-Cumulative Preference Share (the " 5.625% PRE Preference Shares") and (c) Depositary Share, each representing a 1/1000th interest in a share of 7.000% Perpetual Non-Cumulative Preference Shares (the "7.000% PRF Preference Shares" and, collectively with the 5.625% PRD Preference Shares and the 5.625% PRE Preference Shares, the "Preference Shares") of Aspen by virtue of the Merger and without any action on the part of the holder thereof, were automatically converted into a fully paid preference share of the Surviving Company, in each case, entitled to the same dividend and all other preferences and privileges, rights, qualifications, limitations, and restrictions set forth in the applicable certificate of designations of each Preference Share, which such certificate of designation remaining at and following the Effective Time in full force and effect. As from the Effective Time, each issued share of Merger Sub was converted into a common share, par value $1.00, of the Surviving Company.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Following the Effective Time, the Company's Ordinary Shares were delisted from The New York Stock Exchange and deregistered under the Securities Exchange Act of 1934, as amended. The Company remains subject to certain applicable reporting requirements of the Securities Exchange Act of 1934, as amended, as a result of its Preference Shares continuing to be listed on the NYSE. Accordingly, the Company expects to continue filing annual reports on Form 20-F with the U.S. Securities and Exchange Commission. The Company may from time to time seek to redeem or repurchase and/or delist the Preference Shares.

As at the date of this report, the Company's Ordinary Shares and the Preference Shares are listed on the NYSE under the following ticker symbols: AHL, AHL PRD, AHL PRE and AHL PRF, respectively.

**2.&nbsp;&nbsp;&nbsp;&nbsp;Basis of Presentation and Significant Accounting Policies**

The consolidated financial statements of Aspen Holdings are prepared in accordance with United States Generally Accepted Accounting Principles ("U.S. GAAP") and are presented on a consolidated basis including the transactions of all operating subsidiaries in which the Company has a controlling financial interest and variable interest entities ("VIE") in which the Company is considered to be the primary beneficiary. Transactions between Aspen Holdings and its subsidiaries are eliminated within the consolidated financial statements.

The consolidated financial statements have been prepared on a going concern basis.

&nbsp;&nbsp;&nbsp;&nbsp;**(a)**&nbsp;&nbsp;&nbsp;&nbsp;**Use of Estimates** 

Assumptions and estimates made by management have a significant effect on the amounts reported within the consolidated financial statements. The most significant of these relate to losses and loss adjustment expenses, reinsurance recoverables, gross written premiums and commissions which have not been reported to the Company such as those relating to proportional treaty reinsurance contracts, unrecognized tax benefits, recoverability of deferred tax assets, the fair value of derivatives and the fair value of other and privately-held investments. All material assumptions and estimates are regularly reviewed and adjustments made as necessary but actual results could be significantly different from those expected when the assumptions or estimates were made.

&nbsp;&nbsp;&nbsp;&nbsp;**(b)**&nbsp;&nbsp;&nbsp;&nbsp;**Accounting for Insurance and Reinsurance Operations** 

*Premiums Earned.* Premiums are generally recorded as written on the inception date of a policy. For proportional reinsurance treaty contracts, written premiums are generally recorded as the reinsured policies attach to the treaty. For multi-year insurance or reinsurance contracts, written premiums are recorded based on the contract terms. Premiums are recognized as revenues proportionately over the coverage period. Premiums earned are recorded in the consolidated statements of operations, net of the cost of purchased reinsurance. Premiums written which are not yet recognized as earned premium are recorded in the consolidated balance sheet as unearned premiums. Written and earned premiums and the related costs include estimates for premiums which have not been finally determined. These relate mainly to contractual provisions for the payment of adjustment or additional premiums, premiums payable under proportional treaties and delegated underwriting authorities, and reinstatement premiums.

Adjustment and additional premiums are premiums charged which relate to experience during the policy term. The proportion of adjustable premiums included in the premium estimates varies between business lines with the largest adjustment premiums being in property and casualty reinsurance, marine, aviation and energy insurance and the smallest in property and casualty insurance.

Premiums under proportional treaty contracts and delegated underwriting authorities are generally not reported to the Company until after the reinsurance coverage is in force. As a result, an estimate of these "pipeline" premiums is recorded. The Company estimates pipeline premiums based on projections of ultimate premium taking into account reported premiums and expected development patterns.

Reinstatement premiums on assumed excess of loss reinsurance contracts are provided based on experience under such contracts. Reinstatement premiums are the premiums charged for the restoration of the reinsurance limit of an excess of loss contract to its full amount after payment by the reinsurer of losses as a result of an occurrence. The original premiums are recognized as revenue in full at the date of loss, with the reinstatement premiums recognized as revenue over the remaining cover term. Reinstatement premiums provide future insurance cover for the remainder of the initial policy term.

*Credit Losses on Underwriting Premiums Receivable.* Underwriting premium receivable balances are reported net of an allowance for expected credit losses. The allowance, based on ongoing review and monitoring of amounts outstanding, historical loss data, including write-offs and other current economic factors, is charged to net income in the period the receivable is recorded and revised in subsequent periods to reflect changes in the Company's estimate of expected credit losses. For most insurance policies, credit risk is partially mitigated by the Company's ability to cancel the policy if the policyholder does not pay the premium whereby, upon default, policy liabilities would be written-down along with premium receivables.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Losses and Loss Adjustment Expenses.* Losses represent the amount paid or expected to be paid to claimants in respect of events that have occurred on or before the balance sheet date. The costs of investigating, resolving and processing these claims are known as loss adjustment expenses ("LAE"). The consolidated statements of operations records these losses net of reinsurance, meaning that gross losses and loss adjustment expenses incurred are reduced by the amounts recovered or expected to be recovered under reinsurance contracts.

*Reinsurance.* Written premiums, earned premiums, incurred claims, LAE and the acquisition costs all reflect the net effect of assumed and ceded reinsurance transactions. Assumed reinsurance refers to the Company's acceptance of certain insurance risks that other insurance companies have underwritten. Ceded reinsurance arises from contracts under which other insurance companies agree to share certain risks with the Company.

Reinsurance accounting is followed when there is risk transfer, which includes significant timing risk, underwriting risk, and where applicable, a reasonable possibility of significant loss.

Outward reinsurance premiums, which are paid when the Company purchases reinsurance or retrocessional coverage, are accounted for using the same accounting methodology as the Company uses for inwards premiums. Premiums payable under reinsurance contracts that operate on a "losses occurring during" basis are expensed over the period of coverage while those arising from "risks attaching during" policies are expensed over the earnings period of the underlying premiums written from the reinsured business. Adjustment premiums and reinstatement premiums in relation to outward reinsurance are accrued when it is determined that the ultimate losses will trigger a payment and recognized within premiums payable. Reinsurance and retrocession does not isolate the ceding company from its obligations to policyholders. In the event that a reinsurer or retrocessionaire fails to meet its obligations, the ceding company's obligations remain.

*Accounting for Retroactive Reinsurance Agreements.* Retroactive reinsurance agreements are reinsurance agreements under which a reinsurer agrees to reimburse the Company as a result of past insurable events. For retroactive reinsurance purchased by the Company, the excess of the amounts ultimately collectible under the agreement over the consideration paid is recognized as a deferred gain liability which is amortized into income over the settlement period of the ceded reserves once the paid losses have exceeded the minimum retention. The amount of the deferral is recalculated each period based on actual loss payments and updated estimates of ultimate losses. If the consideration paid exceeds the ultimate losses collectible under the agreement, the net loss on the retroactive reinsurance agreement is recognized within income immediately.

Premiums payable for retroactive reinsurance coverage and meeting the conditions of reinsurance accounting are reported as reinsurance recoverables to the extent that those amounts do not exceed recorded liabilities relating to underlying reinsurance contracts. Premiums paid in excess of accounts receivable are charged to income.

*Reserves.* Insurance reserves are established for the total unpaid cost of claims and LAE in respect of events that have occurred by the balance sheet date, including the Company's estimates of the total cost of claims incurred but not yet reported ("IBNR"). Claim reserves are reduced for estimated amounts of salvage and subrogation recoveries. Estimated amounts recoverable from reinsurers on unpaid losses and LAE are reflected as assets.

For reported claims, reserves are established on a case-by-case basis within the parameters of coverage provided in the insurance policy or reinsurance agreement. For IBNR claims, reserves are estimated using a number of established actuarial methods to establish a range of estimates from which a management best estimate is selected. Both case and IBNR reserve estimates consider variables such as past loss experience, changes in legislative conditions, changes in judicial interpretation of legal liability, policy coverages and inflation.

As many of the coverages underwritten involve claims that may not be ultimately settled for many years after they are incurred, subjective judgments as to the ultimate exposure to losses are an integral and necessary component of the loss reserving process. The Company regularly reviews its reserves, using a variety of statistical and actuarial techniques to analyze current claims costs, frequency and severity data, and prevailing economic, social and legal factors. Reserves established in prior periods are adjusted as claim experience develops and new information becomes available. Adjustments to previously estimated reserves are reflected in the financial results of the period in which the adjustments are made.

The process of estimating required reserves does, by its very nature, involve considerable uncertainty. The level of uncertainty can be influenced by factors such as the existence of coverage with long duration payment patterns and changes in claims handling practices, as well as the factors noted above. Ultimate actual payments for claims and LAE could turn out to be significantly different from the Company's estimates.

*Credit Losses on Reinsurance Recoverables.* Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability with the reinsured business. The Company maintains credit risk if a reinsurer is unable to pay recoverables when they become due. To manage this risk, the Company evaluates the financial condition of its reinsurers and retrocessionaires, and monitors concentration of credit risk to minimize its exposure to significant losses from individual reinsurers. To further reduce credit exposure on reinsurance recoverables, the Company has received collateral, including letters of credit and trust accounts, from certain reinsurers. Following the adoption of ASC 326, an allowance is established for expected credit losses to be recognized over the life of the reinsurance recoverable. The allowance considers the current financial strength of the individual reinsurer and the amount of collateral held.

*Acquisition Costs.* The costs directly related to writing a (re)insurance policy are referred to as acquisition expenses and include commissions, premium taxes and profit commissions. With the exception of profit commissions, these expenses are incurred when a policy is issued, and only the costs directly related to the successful acquisition of new and renewal insurance and reinsurance contracts are deferred and amortized over the same period as the corresponding premiums are recorded as revenues. Profit commissions are estimated and accrued based on the related performance criteria evaluated at the balance sheet date, with subsequent changes to those estimates recognized when they occur. Commissions received related to reinsurance premiums ceded are netted against broker commissions in determining acquisition costs eligible for deferral.

On a regular basis a premium deficiency analysis is performed of the deferred acquisition costs in relation to the expected recognition of revenues, including anticipated investment income, and adjustments, if any, are reflected as period costs. Should the analysis indicate that the acquisition costs are unrecoverable, further analyses are performed to determine if a reserve is required to provide for losses which may exceed the related unearned premium.

*General and Administrative Expenses.* These costs represent the expenses incurred in running the business and include, but are not limited to compensation costs for employees, rental costs, IT development and professional and consultancy fees. General and administrative costs directly attributable to the successful acquisition of business are deferred and amortized over the same period as the corresponding premiums are recorded as revenues. When reporting the results for its business segments, the Company includes expenses which are directly attributable to the segment plus an allocation of central administrative costs.

*Corporate Expenses.* Corporate expenses are not allocated to the Company's business segments as they typically do not fluctuate with the levels of premium written and are related to the Company's operations which include group executive costs, group finance costs, group legal and actuarial costs and certain strategic and other costs.

&nbsp;&nbsp;&nbsp;&nbsp;**(c)**&nbsp;&nbsp;&nbsp;&nbsp;**Accounting for Investments, Cash and Cash Equivalents** 

*Fixed Income Securities.* The fixed income securities portfolio comprises securities issued by governments and government agencies, corporate bonds, mortgage and other asset-backed securities and bank loans. Investments in fixed income securities are classified as available for sale or trading and are reported at estimated fair value in the consolidated balance sheet. Investment transactions are recorded on the trade date with balances pending settlement reflected in the consolidated balance sheet under receivables for securities sold and payables for securities purchased, respectively. Fair values are based on quoted market prices and other data provided by third-party pricing services.

*Short-term Investments.* Short-term investments primarily comprise highly liquid debt securities with a maturity greater than three months but less than one year from the date of purchase and are held as part of the investment portfolio of the Company. Short-term investments are classified as either trading or available for sale and reported at estimated fair value.

*Catastrophe Bonds.* Investments in catastrophe bonds are classified as trading and are reported on the consolidated balance sheet at estimated fair value. The fair values are based on independent broker-dealer quotes.

*Privately-held Investments.* The Company's privately-held investments primarily comprise commercial mortgage loans, middle market loans and other private debt, asset-backed securities and global corporate securities. These investments are classified as trading or available for sale and are reported on the consolidated balance sheet at estimated fair value. Privately-held investments are initially valued at cost or transaction value which approximates fair value. In subsequent measurement periods, the fair values of these securities are primarily determined using discounted cash flow models. Interest income is accrued on the principal amount of the loan based on its contractual interest rate subject to it being probable that we will receive interest on that particular underlying loan. Interest income, amortization of premiums and discounts, and prepayment fees are reported in net investment income on the consolidated statements of income.

*Investments, Equity Method.* These investments represent the Company's investments in partially owned insurance and related companies that are recorded using the equity method of accounting. The carrying value of these investments are based on the Company's proportionate share of GAAP equity.

*Other Investments.* Other investments represent the Company's investments in investment funds that are reported at net asset value. For these investments, net asset value is used as a practical expedient for fair value.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

*Cash and Cash Equivalents.* Cash and cash equivalents are reported at fair value. Cash and cash equivalents comprise cash on hand, deposits held on call with banks and other short-term highly liquid investments due to mature within three months from the date of purchase and which are subject to insignificant risk of change in fair value.

*Gains and Losses.* Realized gains or losses on the sale of investments are determined on the basis of the first in first out cost method and are recorded in revenue or expenses respectively. Unrealized gains and losses represent the difference between the cost, or the cost as adjusted by amortization of any difference between its cost and its redemption value ("amortized cost"), of the security and its fair value at the reporting date and are included within other comprehensive income for securities classified as available for sale and in realized and unrealized investment gains or losses in the consolidated statement of operations for securities classified as trading.

*Credit Losses on Available for Sale Debt Securities*. An allowance account for credit losses is recognized for available for sale debt securities based on a review of individual securities. Write-offs are recorded when amounts are deemed uncollectible, or Aspen intends to sell (or more likely than not will be required to sell) the debt security before recovery of the amortized cost basis. The amortized cost basis will be written down to the debt securities fair value through earnings. Credit losses are limited to the difference between the debt securities amortized cost basis and fair value. Any decline in the debt securities fair value below the amortized cost basis that is not a result of a credit loss is recorded through other comprehensive income, net of applicable taxes. The allowance for credit losses of a security may be increased or reversed upon a change in credit position with the change reflected in net income.

The credit loss models employ a discounted cash flow approach to evaluate whether a credit loss exists at the individual security level and are reviewed at each reporting period. This analysis excludes investments in U.S. Government / Agency bonds and U.S. Government Agency mortgage-backed securities due to being of 'high credit quality' based on the absence of risk. For any available for sale debt securities that were initially purchased with credit deterioration, the amortized cost basis shall be considered to be the purchase price, plus any allowance for credit losses. Estimated credit losses shall be discounted at the rate that equates the present value of the purchaser's estimate of the security's future cash flows with the purchase price of the asset.

*Net Investment Income.* Investment income includes amounts received and accrued in respect of periodic interest ("coupons") payable to the Company by the issuer of fixed income securities, equity dividends and interest credited on cash and cash equivalents. It also includes amortization of premium and accretion of discount in respect of fixed income securities. Investment income also includes changes in fair value from investments in real estate funds. Investment management and custody fees are charged against net investment income reported in the consolidated statement of operations.

&nbsp;&nbsp;&nbsp;&nbsp;**(d)**&nbsp;&nbsp;&nbsp;&nbsp;**Accounting for Derivative Financial Instruments** 

The Company enters into derivative instruments to manage certain market risks, such as forward exchange contracts used to reduce foreign currency risk relative to the U.S. dollar. The Company records derivative instruments at fair value on the Company's consolidated balance sheet as either assets or liabilities, depending on their rights and obligations.

The accounting for the gain or loss due to the changes in the fair value of these instruments is dependent on whether the derivative qualifies as a hedge. If the derivative does not qualify as a hedge, the gains or losses are reported in the consolidated statement of operations when they occur and classified within *Change in fair value of derivatives*. If the derivative qualifies as a hedge, the accounting treatment varies based on the type of risk being hedged. There are two primary types of hedging relationships that may be used for accounting purposes: fair value hedge and cash flow hedge. A fair value hedge is designed to offset changes in the fair value of an underlying asset or liability, and the gain or loss from the hedging instrument offsets the change in fair value of the underlying asset or liability. Under fair value hedge accounting, both the gain or loss from the underlying asset or liability and the gain or loss from the hedging instrument are recognized in earnings in the same period. In contrast, a cash flow hedge is designed to offset changes in cash flows of an underlying asset or liability. The gain or loss from the hedging instrument is initially recognized in other comprehensive income. As the contracts settle, the realized gain or loss is reclassified from other comprehensive income into the consolidated statement of operations.

The loss portfolio transfer contract included a funds withheld arrangement that provided a variable interest expense based on Aspen's investment performance. As a result, this funds withheld arrangement was considered an embedded derivative and accounted for as an option-based derivative. Since the economic characteristics and risks of an embedded derivative feature are not clearly and closely related to the economic characteristics and risks of the host contract, the embedded derivative was bifurcated and accounted for separately at fair value. The Company records subsequent changes in the embedded derivative fair value in the consolidated statement of operations.

&nbsp;&nbsp;&nbsp;&nbsp;**(e)&nbsp;&nbsp;&nbsp;&nbsp;Accounting for Intangible Assets** 

Intangible assets are held in the consolidated balance sheet at cost less amortization and impairment. Amortization applies on a straight-line basis in respect of assets having a finite estimated useful economic life. Finite intangibles are assessed on an annual basis for impairment, or more frequently where circumstances indicate the carrying value may not be recoverable. For intangible assets considered to have an indefinite life, the Company performs a qualitative assessment annually to determine whether it is more likely than not that an intangible asset is impaired. Goodwill is assessed annually for impairment or more frequently if circumstances indicate an impairment may have occurred.

&nbsp;&nbsp;&nbsp;&nbsp;**(f)**&nbsp;&nbsp;&nbsp;&nbsp;**Accounting for Office Properties and Equipment** 

Office properties and equipment are reported at cost less accumulated depreciation. These assets are depreciated on a straight-line basis over the estimated useful lives of the assets. Computer equipment is depreciated between three and five years, furniture and fittings are depreciated over four years and leasehold improvements are depreciated over the lesser of 15 years or the lease term.

IT development costs that are directly associated with the development of identifiable and unique software products and that are anticipated to generate economic benefits exceeding costs beyond one year, are recognized within office properties and equipment. Costs include external consultants' fees, certain qualifying internal staff costs and other costs incurred to develop software programs. Software is depreciated over their estimated useful life, between three and five years, on a straight-line basis and is subject to impairment testing annually. Depreciation commences when the asset becomes operational. Other non-qualifying costs are expensed as incurred.

&nbsp;&nbsp;&nbsp;&nbsp;**(g)**&nbsp;&nbsp;&nbsp;&nbsp;**Accounting for Leases** 

In the ordinary course of the business, the Company renews and enters into new leases for office real estate and other assets. At the lease inception date, the Company determines whether a contract contains a lease and recognizes operating lease Right-of-use assets and operating lease liabilities based on the present value of future minimum lease payments. As our leases do not provide an implicit interest rate, we use our incremental borrowing rate based on the information available at the commencement date to determine the present value of future payments. For all office real estate leases, rent incentives, including reduced-rent and rent-free periods and contractually agreed rent increases during the lease term, have been included when determining the present value of future cash flows.

Right-of-use operating lease assets are reported at cost less accumulated depreciation on the consolidated balance sheet and depreciated over the lease term. The Company does not record office property and equipment leases with an initial term of 12 months or less (short-term) in the Company's consolidated balance sheets. Such short-term leases are expensed through the consolidated statement of operations.

Right-of-use operating lease assets are tested for impairments whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. If the carrying value of an asset is impaired, it is reduced to the recoverable amount by an immediate charge to the income statement. The recoverable amount is the higher of an asset's fair value less costs to sell and value in use.

&nbsp;&nbsp;&nbsp;&nbsp;**(h)**&nbsp;&nbsp;&nbsp;&nbsp;**Accounting for Foreign Currencies Translation** 

The functional currency of the Company and its subsidiaries is the U.S. Dollar, which is also the Company's reporting currency. Transactions in currencies other than the functional currency are measured at the exchange rate prevailing at the date of the transaction.

Monetary assets and liabilities denominated in non-functional currencies are remeasured at the exchange rate prevailing at the balance sheet date and any resulting foreign exchange gains or losses are reflected in the consolidated statement of operations. Foreign exchange gains or losses related to available for sale investments denominated in non-functional currencies are included within other comprehensive income. Non-monetary assets and liabilities are remeasured to functional currency at historic exchange rates.

&nbsp;&nbsp;&nbsp;&nbsp;**(i)**&nbsp;&nbsp;&nbsp;&nbsp;**Accounting for Income Taxes** 

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. When the Company does not believe that, on the basis of available information, it is more likely than not that deferred tax assets will be fully recovered, it recognizes a valuation allowance against its deferred tax assets to reduce the deferred tax assets to the amount more likely than not to be realized. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

Furthermore, a tax benefit from a tax position may be recognized in the financial statements only if it is more-likely-than-not that the position is sustainable, based solely on its technical merits and consideration of the relevant tax authority's widely understood administrative practices and precedents.

The Company applies a portfolio approach to release the income tax effects in accumulated other comprehensive income. Under this approach, the income tax effects upon the sale of an available for sale debt security, settlement of hedged transactions and upon foreign currency translation adjustments for each period, are determined under the intra-period tax allocation approach. Any tax effects remaining in accumulated other comprehensive income are only released when the entire portfolio is liquidated, sold or extinguished.

The Company has or will claim substance-based refundable tax credits it is eligible for in Bermuda. These refundable tax credits are generally based on a percentage of eligible expenditures related to compensation costs, other operating expenses and corporate expenses. The Company recognizes the benefit of refundable tax credits as reductions to the related expenses in the consolidated statement of operations in the period it is probable the conditions for receiving the refundable tax credit will be satisfied.

&nbsp;&nbsp;&nbsp;&nbsp;**(j)**&nbsp;&nbsp;&nbsp;&nbsp;**Accounting for Preference Shares** 

The Company had at the balance sheet date in issue three classes of preference shares. The Company has no obligation to pay interest on these securities but they carry entitlements to dividends payable at the discretion of the Board of Directors. In the event of non-payment of dividends for six consecutive periods, holders of preference shares have director appointment rights. The preference shares are therefore accounted for as equity instruments and included within total shareholders' equity.

 **(k)**&nbsp;&nbsp;&nbsp;&nbsp;**Accounting for Share-Based Payments and Long-Term Incentive Plans** 

The Company operates an employee long-term incentive plan, comprised of Performance Units and Exit Units, the terms and conditions of which are described in Note 17. The Company applies a fair-value based measurement method in calculating the compensation costs of Performance Units which are recognized on a straight-line basis over the vesting period.

During 2023, selected senior employees were granted Management Equity Plan ("MEP") stock options to acquire non-voting shares at a management equity vehicle affiliated with the Company at no cost to the employee. Upon completion of the Company's IPO, the Company introduced the 2025 Equity and Incentive Plan which granted replacement awards in substitution for the MEP legacy share options.

The Company issued incentive share options and restricted share units to certain eligible employees, directors and other service providers. The Company measures compensation expense for all share-based payment awards based on estimated fair values at the grant date. The fair value of stock options is estimated using the Black-Scholes option pricing model, which requires the input of subjective assumptions including expected volatility, expected term, risk-free interest rate, and dividend yield. Compensation expense is recognized over the period for which the employee, director or service provider is required to provide services in exchange for the award. The Company has elected to estimate expected forfeitures over the requisite service period.

At the Effective Time, each outstanding and unexercised stock option award (a "Company Option Award") that has an exercise price per Company Share less than the Merger Consideration will be canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (a) the amount by which the Merger Consideration exceeds the applicable per share exercise price of the Company Option Award and (b) the number of Company Shares subject to the Company Option Award (a "Restricted Option Award"), and each Company Option Award with an exercise price per Company Share equal to or greater than the Merger Consideration will be canceled for no consideration. Additionally, at the Effective Time, each outstanding restricted share unit award (a "Company RSU Award") will be canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (x) the Merger Consideration and (y) the number of Company Shares subject to the Company RSU Award (together with the Restricted Option Awards, a "Restricted Cash Award"). Each Restricted Cash Award will continue to be subject to the same terms and conditions as the corresponding Company Option Award or Company RSU Award except that, (i) the vested portion of each Restricted Option Award will be paid within 15 days after the applicable vesting date, and (ii) if an individual's employment or service is terminated by the Company or its affiliates without "cause" on or following the Effective Time, all Restricted Cash Awards then-held by such individual will vest in full and be paid within 60 days following the date of such individual's termination of employment, subject to execution and non-revocation of a standard release of claims.

&nbsp;&nbsp;&nbsp;&nbsp;**(l)&nbsp;&nbsp;&nbsp;&nbsp;Accounting for Business Combinations**&nbsp;&nbsp;&nbsp;&nbsp;

The Company accounts for a transaction as a business combination where the assets acquired and liabilities assumed following a transaction constitute a business. An acquired entity must have inputs and processes that make it capable of generating a return or economic benefit to be considered a business. If the assets acquired are not a business, the Company accounts the transaction as an asset acquisition. The Company recognizes and measures at fair value 100 percent of the assets and liabilities of any acquired business. Goodwill is recognized and measured as the difference between the consideration paid or payable less the fair value of assets acquired.

The Company accounts for the disposal of subsidiary undertakings when it ceases to control the subsidiary's assets and liabilities or the group of assets. A gain or loss is recognized and measured as the difference between the fair value of consideration received or receivable and the value of assets, liabilities and equity components de-recognized, related to that subsidiary or group of assets when deconsolidated.

Costs that are directly related to a business combination transaction are expensed in the periods in which the costs are incurred and the services are received.

&nbsp;&nbsp;&nbsp;&nbsp;**(m)&nbsp;&nbsp;&nbsp;&nbsp;Accounting Pronouncements** 

***Accounting Pronouncements Adopted***

In December 2023, the FASB issued ASU 2023-09, "Income Taxes (Topic 740) – Improvements to Income Tax Disclosures". The amendments in this Update provide additional transparency about income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information. These amendments should be applied on a prospective basis, with the option to apply retrospectively. ASU 2023-09 became effective for the year ended December 31, 2025, and the required disclosures have been included within these consolidated financial statements on a prospective basis, where applicable.

***Accounting Pronouncements Not Yet Adopted***

In November 2024, the FASB issued ASU No. 2024-03, "*Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses*". This ASU requires disclosure, in the notes to the financial statements, of specified information about certain costs and expenses. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. As this guidance relates solely to financial statement disclosures, the adoption of ASU 2024-03 will have no impact upon the Company's results of operations, financial condition, or liquidity.

In September 2025, the FASB issued Accounting Standards Update ("ASU") No. 2025-06, "Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software." This ASU amends the accounting guidance for internal-use software to better reflect current development practices by (i) eliminating the requirement to assess software development stages, (ii) introducing a principles-based capitalization threshold, and (iii) consolidating website development cost guidance. The amendments in this ASU are effective for annual and interim periods beginning after December 15, 2027. The Company has evaluated the impact of ASU 2025-06 and determined that its adoption will not have a material impact on its consolidated financial statements.

Other accounting pronouncements were issued during the year ended December 31, 2025 which were either not applicable to the Company or did not impact the Company's consolidated financial statements.

**3.&nbsp;&nbsp;&nbsp;&nbsp;Segment Reporting**

The Company manages its underwriting operations as two business segments: Insurance and Reinsurance. The Company has determined its reportable segments by taking into account the manner in which the Company's chief operating decision maker ("CODM") makes operating and management decisions and assesses operating performance. As at December 31, 2025 and prior to the Merger, the Company's CODM is the Group Executive Committee, which comprises global heads of key functions and other key business leads.

Income or loss for each of the Company's business segments is measured by underwriting income or loss. Underwriting income 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 the CODM to evaluate the segment's underwriting performance.

*Insurance Segment.* The Insurance segment consists of first party insurance, specialty insurance, casualty and liability insurance, financial and professional lines insurance and other insurance. The other insurance business line includes Aspen Underwriting Limited's participation as a corporate member in Carbon Syndicate 4747 and the Company's digital follow capacity offered through the Ki Lloyd's platform.

*Reinsurance Segment.* The Reinsurance segment consists of property catastrophe reinsurance, other property reinsurance, casualty reinsurance and specialty reinsurance.

*Non-underwriting Disclosures.* The Company provides additional disclosures for corporate and other (non-operating) income and expenses. Corporate and other income and expenses include: corporate expenses, non-operating expenses, net investment income, net realized and unrealized investment gains or losses, changes in fair value of derivatives, interest expenses, net realized and unrealized foreign exchange gains or losses, and income taxes. These income and expense items are not allocated to the Company's business segments as they are not directly related to the Company's business segment operations and this approach is consistent with how the CODM measures the performance of the business segments. The Company does not allocate its assets by business segment as we evaluate underwriting results of each segment separately from the results of our investment portfolio.

The Company uses underwriting ratios as measures of performance. The loss ratio is the ratio of losses and loss adjustment expenses to net earned premiums. The acquisition cost ratio is the ratio of acquisition costs to net earned premiums. The general and administrative expense ratio is the ratio of general and administrative expenses to net earned premiums. The combined ratio is the sum of the loss ratio, the acquisition cost ratio and the general and administrative expense ratio.

At December 31, 2024, 1,170 available for sale securities were in an unrealized loss position of $181.9 million, of which $0.3 million was related to securities below investment grade or not rated.

The unrealized losses of $58.2 million at December 31, 2025 were due to non-credit factors and are expected to be recovered as the related securities approach maturity. The Company does not intend to sell the securities in an unrealized loss position and it is not more likely than not that the Company will be required to sell the investments before recovery of their amortized cost bases.

**5.&nbsp;&nbsp;&nbsp;&nbsp;Variable Interest Entities**

As at December 31, 2025, the Company held an investment in one (December 31, 2024 — one) variable interest entity ("VIE"), namely Peregrine Reinsurance Ltd ("Peregrine").

In November 2016, Peregrine, a subsidiary of the Company, was registered as a segregated accounts company under the Segregated Accounts Companies Act 2000, as amended. As at December 31, 2025, Peregrine had nine segregated accounts which were funded by third-party investors, which are not consolidated.

The Company has determined that Peregrine has the characteristics of a VIE as addressed by the guidance in ASC 810, *Consolidation*. The nine segregated accounts have not been consolidated as part of the Company's consolidated financial statements because the Company is not the primary beneficiary of those accounts. The Company has, however, concluded that it is the primary beneficiary of the Peregrine general fund and, similar to prior reporting periods, the results of the Peregrine general fund are included in the Company's consolidated financial statements.

**6.&nbsp;&nbsp;&nbsp;&nbsp;Fair Value Measurements**

The Company's estimates of fair value for financial assets and liabilities are based on the framework established in the fair value accounting guidance included in ASC Topic 820, "*Fair Value Measurements and Disclosures*." The framework prioritizes the inputs, which refer broadly to assumptions market participants would use in pricing an asset or liability, into three levels.

The Company considers prices for actively traded securities to be derived based on quoted prices in an active market for identical assets, which are Level 1 inputs in the fair value hierarchy. The majority of these securities are valued using prices supplied by pricing services.

The Company considers prices for other securities that may not be as actively traded which are priced via pricing services, vendors and broker-dealers, or with reference to interest rates and yield curves, to be derived based on inputs that are observable for the asset, either directly or indirectly, which are Level 2 inputs in the fair value hierarchy. The majority of these securities are also valued using prices supplied by pricing services.

The Company considers securities, other financial instruments, privately-held investments and derivative insurance contracts subject to fair value measurement whose valuation is derived by valuation models to be based largely on unobservable inputs, which are Level 3 inputs in the fair value hierarchy.

The following tables present the level within the fair value hierarchy at which the Company's financial assets and liabilities are measured on a recurring basis as at December 31, 2025 and December 31, 2024:

______________

(1)&nbsp;&nbsp;&nbsp;&nbsp;The loss portfolio transfer contract included a funds withheld arrangement that provided variable interest expense based on Aspen's investment performance. As a result, the funds withheld arrangement was considered an embedded derivative and accounted for as an option-based derivative.

Transfers of assets into or out of a particular level are recorded at their fair values as of the end of each reporting period consistent with the date of the determination of fair value. During the twelve months ended December 31, 2025, $12.6 million was transferred out of Level 3 and $Nil transferred into Level 3 (December 31, 2024 — $Nil was transferred out of Level 3 and $Nil transferred into Level 3). The transfers out of Level 3, and into Level 2, was due to the availability of observable market inputs.

***Valuation of Fixed Income Securities*.** The Company's fixed income securities are classified as either available for sale or trading and are reported at fair value. As at December 31, 2025 and December 31, 2024, the Company's fixed income securities were valued by pricing services or broker-dealers using standard market conventions. The market conventions utilize market quotations, market transactions in comparable instruments and various relationships between instruments including, but not limited to, yield to maturity, dollar prices and spread prices in determining fair value.

*Independent Pricing Services.* The underlying methodology used to determine the fair value of securities in the Company's available for sale and trading portfolios is by the pricing services. Pricing services will gather observable pricing inputs from multiple external sources, including buy and sell-side contacts and broker-dealers, in order to develop their internal prices.

Pricing services provide pricing for less complex, liquid securities based on market quotations in active markets. Pricing services supply prices for a broad range of securities including those for actively traded securities, such as Treasury and other Government securities, in addition to those that trade less frequently or where valuation includes reference to credit spreads, pay down and pre-pay features and other observable inputs. These securities include Government agency, municipals, corporate and asset-backed securities.

For securities that may trade less frequently or do not trade on a listed exchange, these pricing services may use matrix pricing consisting of observable market inputs to estimate the fair value of a security. These observable market inputs include reported trades, benchmark yields, broker-dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, reference data, and industry and economic factors. Additionally, pricing services may use a valuation model such as an option adjusted spread model commonly used for estimating fair values of mortgage-backed and asset-backed securities. The Company does not derive dollar prices using an index as a pricing input for any individual security.

*Broker-Dealers.* The Company obtains quotes from broker-dealers who are active in the corresponding markets when prices are unavailable from independent pricing services or index providers. Generally, broker-dealers value securities through their trading desks based on observable market inputs. Their pricing methodologies include mapping securities based on trade data, bids or offers, observed spreads and performance of newly issued securities. They may also establish pricing through observing secondary trading of similar securities. Quotes from broker-dealers are non-binding.

The Company obtains prices for all of its fixed income investment securities via its third-party accounting service provider, and in the majority of cases receiving a number of quotes so as to obtain the most comprehensive information available to determine a security's fair value. A single valuation is applied to each security based on the vendor hierarchy maintained by the Company's third-party accounting service provider.

As at December 31, 2025, the Company obtained an average of 2.8 quotes per fixed income investment compared to 3.0 quotes at December 31, 2024.

The Company, in conjunction with its third-party accounting service provider, obtains an understanding of the methods, models and inputs used by the third-party pricing service and index providers to assess the ongoing appropriateness of vendors' prices. The Company and its third-party accounting service provider also have controls in place to validate that amounts provided represent fair values. Processes to validate and review pricing include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• quantitative analysis (e.g., comparing the quarterly return for each managed portfolio to its target benchmark, with significant differences identified and investigated);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• comparison of market values obtained from pricing services and broker-dealers against alternative price sources for each security where further investigation is completed when significant differences exist for pricing of individual securities between pricing sources;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• initial and ongoing evaluation of methodologies used by outside parties to calculate fair value; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• comparison of the fair value estimates to the Company's knowledge of the current market.

Prices obtained from pricing services and broker-dealers are not adjusted by us; however, prices provided by a pricing service, or broker-dealer in certain instances may be challenged based on market or information available from internal sources, including those available to the Company's third-party investment accounting service provider. Subsequent to any challenge, revisions made by the pricing service or broker-dealer to the quotes are supplied to the Company's investment accounting service provider.

Management reviews the vendor hierarchy maintained by the Company's third-party accounting service provider in order to determine which price source provides the most appropriate fair value (i.e., a price obtained from a pricing service with more seniority in the hierarchy will be used over a less senior one in all cases). The hierarchy level assigned to each security in the Company's available for sale and trading portfolios is based upon its assessment of the transparency and reliability of the inputs used in the valuation as of the measurement date. The hierarchy of pricing services is determined using various qualitative and quantitative points arising from reviews of the vendors conducted by the Company's third-party accounting service provider. Vendor reviews include annual due diligence meetings with index providers and pricing services vendors covering valuation methodology, operational walkthroughs and legal and compliance updates.

***Fixed Income Securities*.** Fixed income securities are traded on the over-the-counter ("OTC") market based on prices provided by one or more market makers in each security. Securities such as U.S. Government, U.S. Agency, Non-U.S. Government and investment grade corporate bonds have multiple market makers in addition to readily observable market value indicators such as expected credit spread, except for Treasury securities, over the yield curve. The Company uses a variety of pricing sources to value fixed income securities including those securities that have pay down/prepay features such as mortgage-backed securities and asset-backed securities in order to ensure fair and accurate pricing. The fair value estimates for the investment grade securities in the Company's portfolio do not use significant unobservable inputs or modeling techniques.

*U.S. Government and Agency Securities.* U.S. government and agency securities consist primarily of bonds issued by the U.S. Treasury and corporate debt issued by agencies such as the Federal National Mortgage Association ("FNMA"), the Federal Home Loan Mortgage Corporation ("FHLMC") and the Federal Home Loan Bank. As the fair values of U.S. Treasury securities are based on unadjusted market prices in active markets, they are classified within Level 1. The fair values of U.S. government agency securities are priced using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of U.S. government agency securities are classified within Level 2.

*Municipal Securities.* The Company's municipal portfolio consists of bonds issued by U.S. domiciled state and municipality entities. The fair value of these securities is determined using spreads obtained from broker-dealers, trade prices and the new issue market which are Level 2 inputs in the fair value hierarchy. Consequently, these securities are classified within Level 2.

*Non-U.S. Government.* The issuers for securities in this category are non-U.S. governments and their agents including, but not limited to, the U.K., Australia, Canada, France and Germany. The fair values of certain non-U.S. government bonds, primarily sourced from international indices, are based on unadjusted market prices in active markets and are therefore classified within Level 1. The remaining non-U.S. government bonds are classified within Level 2 as they are not actively traded. The fair values of the non-U.S. agency securities, again primarily sourced from international indices, are priced using the spread above the risk-free yield curve. As the yields for the risk-free yield curve and the spreads for these securities are observable market inputs, the fair values of non-U.S. agency securities are classified within Level 2. In addition, foreign government securities include a portion of the Emerging Market Debt ("EMD") portfolio which is also classified within Level 2.

*Corporate.* Corporate securities consist primarily of short-term, medium-term and long-term debt issued by U.S. and foreign corporations covering a variety of industries and are generally priced by index providers and pricing vendors. Some issuers may participate in government programs which guarantee timely payment of principal and interest in the event of a default. The fair values of these securities are generally determined using the spread above the risk-free yield curve. Inputs used in the evaluation of these securities include credit data, interest rate data, market observations and sector news, broker-dealer quotes and trade volumes. In addition, corporate securities include a portion of the EMD portfolio. The Company classifies these securities within Level 2.

*Mortgage-backed Securities.* Residential and commercial mortgage-backed securities consist of bonds issued by the Government National Mortgage Association, the FNMA and the FHLMC. The fair values of these securities are determined through the use of a pricing model (including Option Adjusted Spread) which uses prepayment speeds and spreads to determine the appropriate average life of the mortgage-backed security. These spreads are generally obtained from broker-dealers, trade prices and the new issue market. As the significant inputs used to price mortgage-backed securities are observable market inputs, these securities are classified within Level 2.

*Asset-backed Securities.* Asset-backed securities are securities backed by notes or receivables against assets other than real estate. The underlying collateral for the Company's asset-backed securities consists mainly of student loans, automobile loans and credit card receivables. These securities are primarily priced by index providers and pricing vendors. Inputs to the valuation process include broker-dealer quotes and other available trade information, prepayment speeds, interest rate data and credit spreads. The Company classifies these securities within Level 2.

***Short-term Investments.*** Short-term investments consist of highly liquid debt securities with a maturity greater than three months but less than one year from the date of purchase. Short-term investments are classified as either trading or available for sale according to the facts and circumstances of the investment held. Short-term investments are valued in a manner similar to the Company's fixed maturity investments and are classified within Levels 1 and 2.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

***Privately-held Investments.*** Privately-held investments are initially valued at cost or transaction value which approximates fair value. In subsequent measurement periods, the fair values of the majority of these securities are determined using discounted cash flow models. These models include inputs that are specific to each investment. The inputs used in the fair value measurements include dividend or interest rates and appropriate discount rates. The selection of an appropriate discount rate is judgmental and is the most significant unobservable input used in the valuation of these securities. A significant increase (decrease) in this input in isolation could result in significantly lower (higher) fair value measurement for privately-held investments. In order to assess the reasonableness of the inputs used in the discounted cash flow models, the Company maintains an understanding of current market conditions, issuer specific information that may impact future cash flows as well as collaboration with independent vendors for most securities to assess the reasonableness of the discount rate being used.

*Commercial Mortgage Loans.* Commercial mortgage loans consist of investments in properties including apartments, hotels, office and retail buildings, other commercial properties and industrial properties. The commercial mortgage loan portfolio is diversified by property type, geographic region and issuer to reduce risks. Commercial Mortgage Loans are initially valued at cost or transaction value which approximates fair value. In subsequent measurement periods, the fair values of these securities are determined using discounted cash flow models and are classified as Level 3.

*Middle Market Loans and Other Private Debt*. The middle market loans consist of investments in senior secured loan positions with full covenants, focused on the middle market in the U.S., Europe and the Caribbean. The other private debt consists of debt securities issued to private investment funds. The middle market loan and other private debt portfolio is diversified by industry type, geographic region and issuer to reduce risks. Middle market loans and other private debt are initially valued at cost or transaction value which approximates fair value. In subsequent measurement periods, the fair values of these securities are determined using discounted cash flow models. In the event that the cash flows are negative or indeterminable, the fair values of these securities are determined using the recovery approach. Consequently, these securities are classified within Level 3.

*Asset-backed Securities*. Asset-backed securities represent interests in underlying pools of diversified referenced assets that are collateralized and backed by future cash flows and these securities are performing. Asset-backed securities are initially valued at cost or transaction value which approximates fair value. In subsequent measurement periods, the fair values of these securities are determined using discounted cash flow models and are classified within Level 3.

*Global Corporate Securities.* The global corporate securities portfolio consists of debt securities issued by U.S. and foreign corporations. The global corporate securities are initially valued at cost or transaction value which approximates fair value. In subsequent measurement periods, the fair values of the trading securities are determined using discounted cash flow models and are classified within Level 3. In subsequent measurement periods, the fair values of the available-for-sale securities are determined using a matrix pricing methodology that applies a yield build-up approach. This approach starts with an appropriate interpolated U.S. Treasury yield and adds spread components for sector-specific credit quality, weighted average life, and issuer capital size. The resulting discount yield is then used in a discounted cash flow model to derive the price of each security. The Company classifies these securities within Level 3.

*Short-term Investments* **—** *Privately-held.* Short-term investments which are classified as privately-held consist of debt securities with a maturity greater than three months but less than one year from the date of purchase. Short-term investments are initially valued at cost or transaction value which approximates fair value. In subsequent measurement periods, the fair values of these securities are determined using discounted cash flow models and are classified within Level 3.

***Catastrophe Bonds.*** Catastrophe bonds are variable rate fixed income instruments with redemption values adjusted based on the occurrence of a covered event, usually windstorms and earthquakes. Catastrophe bonds are classified as trading and reported at fair value. Catastrophe bonds are priced using an average of multiple broker-dealer quotes and as such, are classified within Level 2.

***Foreign Exchange Contracts.*** The foreign exchange contracts which the Company uses to mitigate currency risk are characterized as OTC due to their customized nature and the fact that they do not trade on a major exchange. These instruments trade in a very deep liquid market, providing substantial price transparency and accordingly are classified within Level 2.

***Derivative Liabilities - Loss Portfolio Transfer.*** The LPT embedded derivative is valued using the Black-Scholes model. The two primary inputs of this model are expected claim settlement patterns and expected return of the investment portfolio above a fixed minimum rate over the specified time horizon. The expected claim settlement pattern is determined on an actuarial basis for the cohort of business within scope of the LPT and is consistent with the patterns used in the valuation of technical provisions. The expected return of the investment portfolio, above a fixed minimum rate, directly impacts on the LPT derivative valuation and is subject to changes in the market conditions. In order to assess the reasonableness of the inputs, the Company updates the expected claim settlement patterns on a regular basis while maintaining an understanding of the current market conditions. The LPT embedded derivative is classified within Level 3.

***Other Investments.*** The Company's other investments represent primarily our investments in investment funds operating strategies across real estate, infrastructure and direct lending. Adjustments to the fair values of the investment funds are made based on the net asset value of the investments. The net valuation criteria established by the manager of such investments are established in accordance with the governing documents and the asset manager's valuation guidelines, which include: the discounted cash flows method and the performance multiple approach, which uses a multiple derived from market data of comparable companies or assets to produce operating performance metrics. Alternative valuation methodologies may be employed for investments with unusual characteristics. As the Company is measuring the fair value of these investment funds using the net asset value per share as a practical expedient, they have not been classified in the fair value hierarchy.

***Equity Securities***. The fair values of the equity securities are based on unadjusted quoted market prices in active markets, and as such they are classified within Level 1.

**7.&nbsp;&nbsp;&nbsp;&nbsp;Reinsurance**

The Company purchases retrocession and reinsurance to limit and diversify the Company's risk exposure and to increase its own insurance and reinsurance underwriting capacity. These agreements provide for recovery of losses and loss adjustment expenses from reinsurers. The Company remains liable to the extent that reinsurers do not meet their obligations under these agreements. In line with its risk management objectives, the Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk.

Balances pertaining to reinsurance transactions are reported "gross" on the consolidated balance sheet, meaning that reinsurance recoverable on unpaid losses and ceded unearned premiums are not deducted from insurance reserves but are recorded as assets. For more information on reinsurance recoverables, refer to Note 22, "*Concentrations of Credit Risk — Reinsurance recoverables*" and Note 10, "*Reserve for Losses and Loss Adjustment Expenses*" of these consolidated financial statements.

The effect of assumed and ceded reinsurance on premiums written, premiums earned and losses and loss adjustment expenses for the twelve months ended December 31, 2025, 2024 and 2023 was as follows:

*Current expected credit loss model ("CECL")*. As at December 31, 2025, the Company's allowance for expected credit losses on reinsurance recoverables was $16.2 million (2024 — $27.5 million). For the twelve months ended December 31, 2025 there was a $11.3 million decrease in the CECL allowance on reinsurance recoverables (2024 — $23.8 million increase, 2023 — no change).

The Company is potentially exposed to concentrations of credit risk in respect of amounts recoverable from reinsurers, refer to Note 22, "*Concentrations of Credit Risk — Reinsurance recoverable*s" of these consolidated financial statements for more detail.

*Foreign Exchange Contracts.* The Company uses foreign exchange contracts to manage foreign currency risk associated with our operating expenses but also foreign exchange risk associated with net assets or liabilities in currencies other than the U.S. dollar. A foreign exchange contract involves an obligation to purchase or sell a specified currency at a future date at a price set at the time of the contract. Foreign exchange contracts will not eliminate fluctuations in the value of the Company's assets and liabilities denominated in foreign currencies but rather allow it to establish a rate of exchange for a future point in time.

As at December 31, 2025, the Company held foreign exchange contracts that were not designated as hedges under ASC 815 with an aggregate notional amount of $1,404.0 million (2024 — $1,586.9 million). The foreign exchange contracts are recorded as derivative assets or derivative liabilities in the consolidated balance sheet with changes recorded as a change in fair value of derivatives in the consolidated statement of operations. For the twelve months ended December 31, 2025, the impact of foreign exchange contracts on net income was a gain of $43.9 million (December 31, 2024 — loss of $34.0 million).

As at December 31, 2025, the Company held foreign exchange contracts that were designated as cash flow hedges under ASC 815 with an aggregate notional amount of $186.8 million (2024 — $158.0 million). The foreign exchange contracts are recorded as derivative assets or derivative liabilities in the consolidated balance sheet with the changes in fair value recorded in other comprehensive income. For the twelve months ended December 31, 2025 the company recognized a gain of $6.7 million (December 31, 2024 — loss of $6.5 million) in other comprehensive income.

As the foreign exchange contracts settle, the realized gain or loss is reclassified from other comprehensive income into general, administrative and corporate expenses in the consolidated statement of operations.

*Embedded derivative on loss portfolio contract.* The loss portfolio transfer contract included a funds withheld arrangement that provided returns to the reinsurer based on Aspen's investment performance, guaranteeing a minimum of 1.75% return. Such funds withheld arrangements are examples of embedded derivatives and therefore this instrument was accounted for as an option-based derivative. For the twelve months ended December 31, 2025, the amount recognized as a change in fair value of derivatives in the consolidated statement of operations is a gain of $3.6 million (December 31, 2024 — gain of $12.9 million).

The following tables show an analysis of incurred claims and allocated loss adjustment expenses, net of reinsurance and cumulative paid claims and allocated claim adjustment expenses, net of reinsurance for each of the years ended December 31, 2016 through 2025. Under the LPT agreement, the Company has reinsured net losses incurred on all accident years 2019 and prior. This has resulted in IBNR in the loss development triangles for 2019 and prior to be Nil. The loss development triangles are derived from all business written by the Company as although a limited number of contracts are written which have durations of greater than one year the contracts do not meet the definition of a long duration contract. All amounts included in the following tables related to transactions denominated in a foreign currency have been translated into U.S. Dollars using the exchange rates in effect at December 31, 2025.

The Company has chosen to disaggregate the business in its Insurance segment, for the purposes of these loss development triangles as: Property; Casualty; Marine, Aviation and Energy; and Financial and Professional insurance lines. The Company considers that this presentation of its Insurance lines loss development triangles more precisely reflects meaningful trending information. The Company presents its loss development triangles for the Reinsurance segment in line with the reportable reinsurance lines: Property Catastrophe and Other Property; Casualty; and Specialty.

As noted above, the tax rate in Bermuda, the Company's country of domicile, is currently 15%. Application of the statutory income tax rate for operations in other jurisdictions produces a differential to the expected income tax expense/(benefit) as shown in the table below. The reconciliation between the income tax expense and the amount that would result from applying the statutory rate for the Company, after the adoption of ASU 2023-09, for the twelve months ended December 31, 2025 is provided in the table below:

(2)&nbsp;&nbsp;&nbsp;&nbsp;The decrease in valuation allowance in 2024 related to a change in judgment about the recoverability of deferred tax assets in Aspen UK.

Income tax returns that have been filed by the Company's U.S. Operating Subsidiaries are subject to examination for 2022 and later tax years. The Company's U.K. operating subsidiaries' income tax returns are potentially subject to examination for 2024 and later tax years as these periods are considered "open" by the U.K. Tax Authority. The Company accrues interest and penalties related to an underpayment of income taxes, if applicable, as income tax expenses. The Company does not believe it will be subject to any penalties in any open tax years. No uncertain tax position has been identified in 2025 or 2024. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as at December 31, 2025 or 2024.

Deferred tax liabilities and assets represent the tax effect of carryforwards and temporary differences between the value of assets and liabilities for financial statement purposes and such values as measured by U.K., U.S., Bermuda and other tax laws and regulations.

In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences and carry forwards become deductible or creditable. Management considers the scheduled reversal of existing taxable temporary differences, carryback availability, projected future taxable income, and tax-planning strategies in making this assessment.

As at December 31, 2025, the Company has net operating losses carryforwards for Bermuda corporate income tax purposes of $294.8 million (2024 — $267.0 million), net operating losses carryforwards for U.S. federal income tax purposes of $276.0 million (2024 — $324.8 million), of which $226.4 million relates to the U.S. operating subsidiaries and $49.6 million to Aspen UK's U.S. tax branch. The Company also has net operating losses carryforwards for U.K. corporate tax purposes of $194.6 million (2024 — $249.5 million), deferred syndicate profits of $61.7 million (2024 — $29.3 million), and losses in other jurisdictions of $71.8 million (2024 — $86.1 million).

The $276.0 million that are available to offset future U.S. federal taxable income will expire between 2032 and 2041. The amount of pre-merger net operating losses carryforwards that can be used each year is limited by section 382 to $6.5 million per year for Aspen UK's U.S. tax branch, and $20.8 million per year for the next 15 years for the U.S. operating subsidiaries.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

The net operating losses in Bermuda, the U.K. and other jurisdictions are available to offset future corporate income in those jurisdictions over an indefinite period.

For U.S. federal income tax purposes, the Company has capital loss carryforwards of $85.3 million, of which $47.6 million relates to the U.S. operating subsidiaries and $37.7 million to Aspen UK's branch, expiring between 2026 and 2028.

For U.K. corporate tax purposes, the Company has foreign tax credit carryforwards of $20.2 million (2024 — $22.0 million) which are available to offset future U.K. corporate tax arising on the same foreign source of income over an indefinite period.

A valuation allowance of $17.5 million (2024 — $22.9 million) on U.S. deferred tax assets (which includes these loss carryforwards) has been recognized at December 31, 2025 relating to Aspen UK's U.S. tax branch.

A valuation allowance of $20.3 million (2024 — $26.1 million) has been established against U.K. deferred tax assets.

The U.K., U.S. and other jurisdictions valuation allowance combined total is $49.2 million (2024 — $64.0 million).

&nbsp;&nbsp;&nbsp;&nbsp;**(a)&nbsp;&nbsp;&nbsp;&nbsp;Ordinary Shares** 

*Issued Ordinary Shares.* On March 30, 2025, the Company's Board of Directors approved the exchange of all of the Company's previously issued and outstanding shares, par value $0.01 per share ("Previous Ordinary Shares"), owned by the Company's Parent, for 90,833,333 Class A ordinary shares, par value $0.001 ("Class A Ordinary Shares"). In connection with the Ordinary Share Exchange, the Previous Ordinary Shares were canceled. The Class A Ordinary Shares have the same voting and economic rights as the Previous Ordinary Shares other than par value. Share and per share information included in the accompanying consolidated financial statements and notes to the consolidated financial statements have been retroactively adjusted to reflect the Ordinary Share Exchange for all periods presented.

*Equity and Incentive plan*. During 2023, selected senior employees were granted Management Equity Plan ("MEP") stock options to acquire non-voting shares at a management equity vehicle affiliated with the Company at no cost to the employee. Upon completion of the Company's IPO, the Company introduced the 2025 Equity and Incentive Plan which granted replacement awards in substitution for the MEP legacy share options. As a result, the Company granted 1,306,139 ordinary shares as replacement awards. To satisfy tax withholding and remittance obligations, 301,106 ordinary shares were withheld, resulting in a net issuance of 1,005,033 shares to employees.

At the Effective Time, each outstanding and unexercised stock option award (a "Company Option Award") that has an exercise price per Company Share less than the Merger Consideration will be canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (a) the amount by which the Merger Consideration exceeds the applicable per share exercise price of the Company Option Award and (b) the number of Company Shares subject to the Company Option Award (a "Restricted Option Award"), and each Company Option Award with an exercise price per Company Share equal to or greater than the Merger Consideration will be canceled for no consideration. Additionally, at the Effective Time, each outstanding restricted share unit award (a "Company RSU Award") will be canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (x) the Merger Consideration and (y) the number of Company Shares subject to the Company RSU Award (together with the Restricted Option Awards, a "Restricted Cash Award"). Each Restricted Cash Award will continue to be subject to the same terms and conditions as the corresponding Company Option Award or Company RSU Award except that, (i) the vested portion of each Restricted Option Award will be paid within 15 days after the applicable vesting date, and (ii) if an individual's employment or service is terminated by the Company or its affiliates without "cause" on or following the Effective Time, all Restricted Cash Awards then-held by such individual will vest in full and be paid within 60 days following the date of such individual's termination of employment, subject to execution and non-revocation of a standard release of claims.

Refer to Note 17, "*Share-Based Payments and Long-Term Incentive Plan*", for further details.

Basic earnings per ordinary share are calculated by dividing net income available to holders of Aspen Insurance Holdings Limited's ordinary shares by the weighted average number of ordinary shares outstanding during the period. Diluted earnings per ordinary share are calculated based on the weighted average number of ordinary shares and dilutive potential ordinary shares outstanding during the period of calculation using the treasury stock method.

For further information on the Company's share options, refer to Note 17, "*Share-Based Payments and Long-Term Incentive Plan*".

**14.**&nbsp;&nbsp;&nbsp;&nbsp;**Statutory Requirements and Dividends Restrictions**

As a holding company, the Company relies on dividends and other distributions from its Operating Subsidiaries to provide cash flow to meet ongoing cash requirements, including any future debt service payments and other expenses, and to pay dividends, if any, to our preference and ordinary shareholders. The Company must comply with the provisions of the Bermuda Companies Act 1981, as amended, (the "Companies Act") regulating the payment of dividends and distributions.

The ability of the Company's Operating Subsidiaries to pay the Company dividends or other distributions is subject to the laws and regulations applicable to each jurisdiction, as well as the Operating Subsidiaries' need to maintain capital requirements adequate to maintain their insurance and reinsurance operations and their financial strength ratings issued by independent rating agencies.

------

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

The company law of England and Wales prohibits Aspen UK, AMAL or AUL from declaring a dividend to its shareholders unless it has "profits available for distribution". The determination of whether a company has profits available for distribution is based on its accumulated realized profits and other distributable reserves less its accumulated realized losses. While the U.K. insurance regulatory laws impose no statutory restrictions on a general insurer's ability to declare a dividend, the rules of the Prudential Regulation Authority (the "PRA") require each insurance company within its jurisdiction to maintain its solvency margin at all times. Accordingly, Aspen UK, AMAL and AUL may not pay a dividend if the payment of such dividend would result in their SCR coverage ratio falling below certain levels. In addition, any future changes regarding regulatory requirements, including those described above, may restrict the ability of Aspen UK, AMAL and AUL to pay dividends in the future. As at December 31, 2025, Aspen UK had an accumulated balance of retained losses of approximately $727 million and AUL had an accumulated balance of retained losses of approximately $17 million. Aspen UK held a capital contribution reserve of $879.9 million as at December 31, 2025 which, under certain circumstances, could be distributable.

Aspen Bermuda must comply with the provisions of the Companies Act and the Insurance Act regulating the payment of dividends and distributions. Aspen Bermuda may not in any financial year pay dividends which would exceed 25% of its total statutory capital and surplus, as shown on its statutory balance sheet in relation to the previous financial year, unless it files with the BMA a solvency affidavit at least seven days in advance of payment. As at December 31, 2025, 25% of Aspen Bermuda's statutory capital and surplus amounted to $312.9 million. Aspen Bermuda must also obtain the prior approval of the BMA before reducing its total statutory capital as set out in its previous year's financial statements by 25% or more.

Aspen Specialty and AAIC are subject to North Dakota and Texas law, respectively. Under such law, the maximum ordinary dividend which can be paid by insurance companies without prior regulatory approval is subject to statutory restrictions. Ordinary dividends may only be paid out of earned surplus as distinguished from contributed surplus. The maximum amount of ordinary dividend that can be paid without prior regulatory approval is the greater of 10% of a company's surplus as of December 31 of the preceding year, or the amount of net income from the preceding fiscal year.

Actual and required statutory capital and surplus for the principal Operating Subsidiaries of the Company, excluding its Lloyd's syndicate, as at December 31, 2025 and December 31, 2024 were estimated as follows:

As the sole corporate member of our Lloyd's Syndicate, AUL was required to hold capital at Lloyd's of $1,194.7 million as at December 31, 2025, adjusting funding to meet this level on an annual basis in the following Q2 and not holding less than 90% of this amount at any time. As at December 31, 2025, AUL had capital at Lloyd's of $1,125.9 million of which $450.4 million was provided as Funds at Lloyd's by Aspen Bermuda.

The Bermuda Monetary Authority is the group supervisor of the Company. The laws and regulations of Bermuda require that the Company maintain a minimum amount of group statutory capital and surplus based on the enhanced capital requirement using the group standardized risk-based capital model of the Bermuda Monetary Authority. The Company is also subject to an early-warning level based on 120.0% of the enhanced capital requirement which may trigger additional reporting requirements or other enhanced oversight. The statutory capital requirements of the Company's Operating Subsidiaries are set out above. To the extent that these requirements are met, the Company do not anticipate any dividend restrictions arising as a result of the Company's enhanced capital requirement.

**16.**&nbsp;&nbsp;&nbsp;&nbsp;**Retirement Plans** 

The Company operates defined contribution retirement plans for the majority of its employees at varying rates of their salaries. Total contributions by the Company to the retirement plans were $17.0 million for the twelve months ended December 31, 2025 (2024 — $16.9 million, 2023 — $14.5 million).

**17.&nbsp;&nbsp;&nbsp;&nbsp;Share-Based Payments and Long-Term Incentive Plan**

In 2019, the Company implemented a new long-term incentive scheme, under which annual awards are split equally between Performance Units and Exit Units. Performance units vest after two years subject to the Company achieving certain thresholds of operating income over a two year period. Exit Units vest upon change of control (sale or IPO) and achieving predetermined multiplies of invested capital return targets. Both Performance Units and Exit Units are cash-based awards.

During 2024, the Company amended the long-term incentive scheme, whereby the exit units were replaced by annual cash-based retention awards on a prospective basis. The retention awards vest over a twelve-month period subject to the recipient continuing to remain an employee of Aspen.

The Company's total long-term incentive plan expense for the twelve months ended December 31, 2025 was $6.9 million (December 31, 2024 — $14.6 million), which consists of a charge of $2.6 million (December 31, 2024 — $9.8 million) in relation to Performance Units and $4.3 million (December 31, 2024 — $4.8 million) in relation to Retention Units. The income tax effect of this is not considered to be material. As at December 31, 2025, the Company had recorded a payable of $17.9 million (December 31, 2024 — $20.0 million) related to the long-term incentive plan, which is included within accrued expenses and other payables in the consolidated balance sheet.

Upon the completion of the IPO, the Company introduced the 2025 Equity and Incentive Plan (the "Plan") which provides for the grant of incentive share options, non-qualified share options, share appreciation rights, restricted share awards, restricted share units, other share awards, and performance awards to certain eligible employees, directors and other service providers. The Plan also provides for the grant of ordinary shares as replacement awards in substitution for the MEP legacy share options granted to selected senior employees of the Company. The Company is initially authorized to issue up to 3,633,333 ordinary shares, excluding the replacement awards, under the terms of the Plan. The Company has issued ordinary shares, options and other equity incentives under four arrangements: the replacement awards, the all employee awards, the restricted share unit awards, and the incentive share options. The Company classifies these awards as equity instruments, and has elected to estimate expected forfeitures over the requisite service period.

*Replacement Awards*

During 2023, selected senior employees were granted MEP stock options to acquire non-voting shares at a management equity vehicle affiliated with the Company at no cost to the employee. The introduction of the 2025 Equity and Incentive Plan granted replacement awards in substitution for the MEP legacy share options. As a result, the Company granted 1,306,139 ordinary shares as replacement awards. To satisfy tax withholding and remittance obligations, 301,106 ordinary shares were withheld, resulting in a net issuance of 1,005,033 shares to employees. For the twelve months ended December 31, the Company recognized a compensation cost of $39.2 million in relation to these replacement awards.

*All Employee Awards*

In May 2025, 158,997 restricted share units ("RSUs") were granted to certain eligible employees and other service providers of the Company. These RSUs were granted with a requisite service period of one year, with the awards cliff vesting at the end of the service period. The fair value of these awards was calculated based on the Company's share price at the grant date of the awards, and is amortized as an expense over the requisite service period. The grant date fair value of these awards was $30 per unit.

*Restricted Share Unit Awards*

In May 2025, 623,953 RSUs were granted to selected senior employees of the Company. These RSUs were granted with a requisite service period of three years, with the awards vesting in 1/3 annual installments on each anniversary of the grant date. The fair value of these awards was calculated based on the Company's share price at the grant date of the awards, and is amortized as an expense in accordance with the three year graded vesting schedule. The grant date fair value of these awards was $30 per unit.

*Incentive Share Options*

In May 2025, 626,727 share options were granted to selected senior employees with an exercise price equivalent to the Company's share price at the grant date of the awards. These share options were granted with a requisite service period of three years, with the awards cliff vesting at the end of the service period. Once vested, the options are exercisable for a period of ten years from the date of grant. The fair value of the share options at the grant date was determined using the Black-Scholes option pricing model. The following table shows the fair value of the share options, and the significant inputs used in the Black-Scholes option pricing model:

---

| | |
|:---|:---|
| Fair value per share option | $12.0 |
| Risk-free interest rate <sup>(1)</sup> | 4.05% |
| Dividend yield | —% |
| Expected term <sup>(2)</sup> | 6.5 years |
| Expected term price volatility <sup>(3)</sup> | 30% |

---

______________

(1) The risk-free interest rate was estimated based on the yield on a U.S. treasury zero-coupon bond issued with a remaining term equal to the expected term of the share options.

(2) The contractual term is 10 years from the date of grant.

(3) As the Company does not have sufficient trading history, the expected share price volatility was estimated based on the historical volatilities of a selected peer group of comparable companies over a period commensurate with the expected term of the options.

The total stock compensation expense recognized in the Company's consolidated statements of operations for the twelve months ended December 31, 2025 was $61.5 million. As at December 31, 2025, there was $19.1 million of total unrecognized compensation cost related to non-vested awards, which will be recognized on a weighted average basis during the next 2.2 years.

At the effective time of the Merger, each outstanding and unexercised stock option award (a "Company Option Award") that had an exercise price per Company Share less than the Merger Consideration was canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (a) the amount by which the Merger Consideration exceeded the applicable per share exercise price of the Company Option Award and (b) the number of Company Shares subject to the Company Option Award (a "Restricted Option Award"), and each Company Option Award with an exercise price per Company Share equal to or greater than the Merger Consideration was canceled for no consideration. Additionally, at the Effective Time, each outstanding restricted share unit award (a "Company RSU Award") was canceled and converted into a contingent right to receive an amount in cash, without interest, equal to the product of (x) the Merger Consideration and (y) the number of Company Shares subject to the Company RSU Award (together with the Restricted Option Awards, a "Restricted Cash Award"). Each Restricted Cash Award continued to be subject to the same terms and conditions as the corresponding Company Option Award or Company RSU Award except that, (i) the vested portion of each Restricted Option Award will be paid within 15 days after the applicable vesting date, and (ii) if an individual's employment or service is terminated by the Company or its affiliates without "cause" on or following the Effective Time, all Restricted Cash Awards then-held by such individual will vest in full and be paid within 60 days following the date of such individual's termination of employment, subject to execution and non-revocation of a standard release of claims.

As a result of these modifications, these awards will be accounted for as liability-classified share-based compensation awards under ASC 718. The compensation cost for these awards continues to be recognized over the requisite service period; however, subsequent to the modification date, the awards will be remeasured at fair value at each reporting date until settlement, with changes in fair value recognized as a compensation expense in the consolidated statements of income. The modifications did not result in any changes to compensation cost for the twelve months ended December 31, 2025, as the modification occurred after the reporting period.

**18.&nbsp;&nbsp;&nbsp;&nbsp; Intangible Assets and Goodwill**

Aspen's intangible assets relate to trademarks and licenses to trade in the U.S. and U.K. For the twelve months ended December 31, 2025 and December 31, 2024, the Company had intangible assets and goodwill totaling $19.9 million and $19.9 million, respectively.

The *"*Aspen" trademark, valued at $1.1 million, $16.7 million of insurance licenses and $2.1 million of goodwill are considered to have an indefinite life and are tested annually for impairment or when events or changes in circumstances indicate that these assets might be impaired.

For the year ended December 31, 2025, the Company performed its annual qualitative assessment and determined that it was more likely than not that the remaining intangible assets and goodwill are not impaired.

**19.&nbsp;&nbsp;&nbsp;&nbsp;Operating Leases** 

As at December 31, 2025, the Company has recognized right-of-use operating lease assets of $43.4 million, net of impairment, and operating lease liabilities of $64.7 million. Right-of-use operating lease assets comprise primarily of leased office real estate globally and other assets. For all office real estate leases, rent incentives, including reduced-rent and rent-free periods and contractually agreed rent increases during the lease term, have been included when determining the present value of future cash flows.

As part of the Company's operating effectiveness and efficiency program, the Company has consolidated its office space. Where negotiations are either in advanced stages of discussion and it is probable that the sub-lease transactions will be completed, or the Company has agreed terms to sub-lease our office space, the Company has assessed the right-of-use lease assets for impairment. During the twelve months ended December 31, 2025, no impairment has been recognized on the right-of-use lease asset (2024 — $Nil).

The Company has no lease transactions between related parties.

**Investment Management Relationships**

Alongisde other investment managers that may be appointed from time to time by the Company, AAME provides centralized asset management investment advisory and risk services for the portfolio of the Company's investments and investments of such subsidiaries pursuant to the investment management agreements ("IMAs") that have been entered into with AAME.

In addition, pursuant to the IMAs, AAME may engage sub-advisors or delegates to provide certain of the investment advisory and management services to the Company's subsidiaries. Such sub-advisors may include affiliates of AAME.

Under each of the IMAs, AAME will be paid an annual investment management fee (the "Management Fee") which will be based on a cost-plus structure. The "cost" is comprised of the direct and indirect fees, costs, expenses and other liabilities arising in or otherwise connected with the services provided under the IMAs. The "plus" component will be a mark-up in an amount of up to 25% determined based on an applicable transfer pricing study. The Management Fee will be subject to certain maximum threshold levels, including an annual fee cap of 15 bps of the total amount of investable assets. Affiliated sub-advisors, including Apollo Management International LLP, will also earn additional fees for sub-advisory services rendered.

During the year ended December 31, 2025, the Company recognized IMA fees of $6.4 million (2024 — $9.2 million; 2023 — $9.4 million), of which $2.0 million (2024 — $4.0 million) remains payable to AAME at year end.

The IMAs remained in place following the effective time of the Merger. The Company and its subsidiaries and affiliates, as applicable, may consider and amend the terms of the IMAs from time to time. As from May 9, 2025, fees related to sub-advisory services were no longer payable under the IMAs.

**Management Consulting Agreement**

As previously disclosed, the Company entered into a Management Consulting Agreement, dated March 28, 2019 (the "Management Consulting Agreement"), with AMH.

With effect from the closing of the IPO on May 9, 2025, the Management Consulting Agreement was terminated.

_____________

(1)&nbsp;&nbsp;&nbsp;&nbsp;As at December 31, 2025, the Company had pledged funds of $101.8 million (December 31, 2024 — $153.2 million) as collateral for the secured letters of credit.

(2)&nbsp;&nbsp;&nbsp;&nbsp;Investable assets comprise total investments, cash and cash equivalents, accrued interest, receivables for securities sold and payables for securities purchased.

*Investment Funds.* We invest in investment funds which, as is typical for this type of investment, have lock-up periods. A lock-up period is the initial amount of time an investor is contractually required to remain invested before having the ability to redeem. As at December 31, 2025, the lock-up periods across these funds range from one quarter to several years. Thereafter these funds could also be redeemed on a pro-rata basis depending on the liquidity position of the fund. There are no assurances as to when the Company may be able to withdraw, in whole or in part, its redemption request from the fund.

*Letters of Credit.* The Company's current arrangements with bankers for the issue of letters of credit require us to provide collateral in the form of cash and investments for the full amount of all secured and undrawn letters of credit that are outstanding. We monitor the proportion of our otherwise liquid assets that are committed to trust funds or to the collateralization of letters of credit. As at December 31, 2025 and 2024, these funds amounted to approximately 37.1% of the $8.3 billion and approximately 46.4% of the $7.7 billion of investable assets held by the Company, respectively. We do not consider that this unduly restricts our liquidity at this time. For more information on our credit facilities and long-term debt arrangements, refer to Note 24, "*Credit Facilities and Long-term Debt*" of these consolidated financial statements.

*Funds at Lloyd's.* AUL operates at Lloyd's as the corporate member for Syndicate 4711. AUL also participates in underwriting activities of Carbon Syndicate 4747. Lloyd's determines required regulatory capital by considering the underwriting activities that AUL participates in. Such capital, called Funds at Lloyd's, consists of investable assets as at December 31, 2025 in the amount of $461.7 million (2024 — $471.9 million).

The amounts provided as Funds at Lloyd's will be drawn upon and become a liability of the Company in the event of Syndicate 4711 declaring a loss at a level that cannot be funded from other resources, or if Syndicate 4711 requires funds to cover a short-term liquidity gap. The amount which the Company provides as Funds at Lloyd's is not available for distribution to the Company for the payment of dividends. Aspen Managing Agency Limited, the managing agent to Syndicate 4711, is also required by Lloyd's to maintain a minimum level of capital which as at December 31, 2025 was £0.4 million (December 31, 2024 — £0.4 million). This is not available for distribution by the Company for the payment of dividends.

*U.S. Mortgage Trusts.* Aspen Bermuda, Aspen UK, Aspen Specialty and AAIC maintain trusts for the benefit of their U.S. cedants in accordance with covenants of U.S. mortgage credit risk transfer transactions. As at December 31, 2025, the total balance held in trust was $547.4 million (December 31, 2024 —$439.2 million).

*U.S. Reinsurance Trust Fund.* For its U.S. reinsurance activities, Aspen UK has established and must retain a multi-beneficiary U.S. trust fund for the benefit of its U.S. cedants so that they may take financial statement credit without the need to post cedant-specific security. The minimum trust fund amount is $20.0 million plus an amount equal to 100% of Aspen UK's U.S. reinsurance liabilities, which were $497.6 million as at December 31, 2025 and $648.8 million as at December 31, 2024. As at December 31, 2025, the balance (including applicable letter of credit facilities) held in the trust was $718.6 million (2024 — $1,001.5 million).

&nbsp;&nbsp;&nbsp;&nbsp;**(b)Contingencies&nbsp;&nbsp;&nbsp;&nbsp;**

In common with the rest of the insurance and reinsurance industry, the Company is also subject to litigation and arbitration in the ordinary course of business. The Company's Operating Subsidiaries are regularly engaged in the investigation, conduct and defense of disputes, or potential disputes, resulting from questions of insurance or reinsurance coverage or claims activities. Pursuant to insurance and reinsurance arrangements, many of these disputes are resolved by arbitration or other forms of alternative dispute resolution. Such legal proceedings are considered in connection with estimating the Company's Reserve for Losses and Loss Adjustment Expenses, as provided on the Company's consolidated balance sheet.

In some jurisdictions, noticeably the U.S., a failure to deal with such disputes or potential disputes in an appropriate manner could result in an award of "bad faith" punitive damages against the Company's Operating Subsidiaries. In accordance with ASC 450-20-50-3, for (a) reasonably possible losses for which no accrual is made because any of the conditions for accrual in ASC 450-20-25-2 are not met and (b) reasonably possible losses in excess of the amounts accrued pursuant to ASC 450-20-30-1, the Company will provide an estimate of the possible loss or range of possible loss or state that such an estimate cannot be made.

Cavello Bay Reinsurance Limited ("Cavello Bay") commenced proceedings against the Company in the State of Connecticut Superior Court on August 22, 2025. The case was subsequently refiled in the Supreme Court of the State of New York on October 17, 2025.

Cavello Bay claim that the Company has breached the Loss Portfolio Transfer Reinsurance Agreement entered into in January 2022 in the following respects:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) &nbsp;&nbsp;&nbsp;&nbsp;by refusing to comply with the Company's contractual obligations to identify and pay or credit premiums collected after October 1, 2021 in respect of the reinsured policies (the "Collected Premium Issue"). Cavello Bay suggest that this claim amounts to a sum in excess of $150.0 million plus prejudgment interest;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;by refusing to comply with the Company's contractual obligations to pay claims with dates of loss after January 1, 2020 under contracts that straddle the period before and after that date (the "Straddle Account Issue"). Cavello Bay claim that the Company is responsible for more than $50.0 million in paid claims and reserves which are currently allocated to Cavello Bay; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp;by refusing to apply proper dates of loss to construction defect claims where the loss occurred partially or entirely after December 31, 2019 (the "Construction Defect Issue"). Cavello Bay claim that the Company's share of Construction Defect claims will exceed $100.0 million.

The Company has appointed the law firms Troutman Pepper Locke and DWF to represent it. In line with these firms' recommendations, the Company is:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;fully defending each of Cavello Bay's claims, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;bringing certain counterclaims.

As at December 31, 2025, other than the matters noted above, based on available information, it is not possible to reasonably estimate the likelihood or the full financial impact of the asserted claims or extent of the set-off or other changes to the Company's potential exposure.

**22.**&nbsp;&nbsp;&nbsp;&nbsp;**Concentrations of Credit Risk** 

The Company is potentially exposed to concentrations of credit risk in respect of amounts recoverable from reinsurers, investments and cash and cash equivalents, and insurance and reinsurance balances owed by the brokers with whom the Company transacts business.

The Company defines credit risk tolerances in line with the risk appetite set by our Board and they, together with the Group's risk management function, monitor exposures to individual counterparties. Any exceptions are reported to senior management and the Risk Committee of the Board of Directors.

**Reinsurance recoverables** 

At December 31, 2025, the total amount recoverable by the Company from reinsurers was $4,281.9 million (December 31, 2024 — $4,172.0 million). Of the Company's reinsurance recoverable balance at December 31, 2025, 61.9% is collateralized by our reinsurers, 37.3% is recoverable from reinsurers rated A- or higher by major rating agencies and 0.8% is recoverable from reinsurers rated lower than A- by major rating agencies (December 31, 2024 — 55.9%, 44.0% and 0.1%, respectively). As at December 31, 2025, the Company's largest uncollateralized exposures to individual reinsurers represent 17.2% (December 31, 2024 —15.4%), 15.1% (December 31, 2024 — 11.5%), and 7.6% (December 31, 2024 — 8.8%) of the uncollateralized reinsurance recoverables.

Under the current expected credit loss model ("CECL"), the Company recognized a provision against reinsurance recoverables of $16.2 million as at December 31, 2025 (December 31, 2024 — $27.5 million). For the twelve months ended December 31, 2025, there was a $11.3 million decrease in the CECL allowance on reinsurance recoverables.

**Underwriting premium receivables** 

The total underwriting premium receivable by the Company as at December 31, 2025 was $1,700.8 million (2024 — $1,617.0 million). As at December 31, 2025, $257.7 million of the total underwriting premium receivable balance has been due for settlement for more than one year. The Company assesses the recoverability of premium receivables through a review of policies and the concentration of receivables by broker. The Company has recognized an allowance for credit losses of $22.9 million as at December 31, 2025 (December 31, 2024 — $24.6 million) on underwriting premium receivables.

**Investments and cash and cash equivalents** 

The Company's investment policies include specific provisions that limit the allowable holdings of a single issue and issuer. As at December 31, 2025, there were no investments in any single issuer, other than the U.S. government and the Canadian government in excess of 2% of the aggregate investment portfolio.

**24.**&nbsp;&nbsp;&nbsp;&nbsp;**Credit Facilities and Long-term Debt**

In the normal course of its operations, the Company enters into agreements with financial institutions to obtain financing through secured and unsecured credit facilities. As at December 31, 2025, the Company had utilized or drawn on approximately $1.4 billion of capital under these facilities, with additional unutilized capacity available, notably approximately $798 million from the Credit Agreement (defined below) and our FHLBB (defined below) line of credit, with the significant facilities as follows:

*Credit Facilities*

On December 1, 2021, Aspen Holdings and certain of its direct or indirect subsidiaries (collectively, the "Borrowers") entered into a Third Amended and Restated Credit Agreement, as further amended from time to time (the "Credit Agreement") with various lenders and Barclays Bank plc, as administrative agent, which amends and restates the Amended and Restated Credit Agreement, dated as of June 12, 2013 and the Second Amended and Restated Credit Agreement, dated as of March 27, 2017, among Aspen Holdings, certain subsidiaries thereof, various lenders and Barclays Bank plc, as administrative agent. The Credit Agreement will be used by the Borrowers to finance the working capital needs of the Aspen Holdings and its subsidiaries, for letters of credit in connection with the insurance and reinsurance businesses of the Company and its subsidiaries and borrowings for other general corporate purposes. Initial availability under the Credit Agreement was $300.0 million and the Company has the right to request (subject to the terms and conditions of the Credit Agreement) an increase to the credit facility by up to $100.0 million. The Credit Agreement will expire on December 1, 2026.

As at December 31, 2025, there were no borrowings outstanding under the Credit Agreement. The fees and interest rates on the loans and the fees on the letters of credit payable by the Borrowers under the Credit Agreement are based upon the credit ratings for the Company's long-term unsecured senior, non-credit enhanced debt rating of the Company, as determined by S&P and Moody's. In addition, the fees for a letter of credit vary based upon whether the applicable Borrower has provided collateral (in the form of cash or qualifying debt securities) to secure its reimbursement obligations with respect to such letter of credit.

<u>[**Table of Contents**](#ic234cba0d6764b21b5bf3826335055fe_7)</u>

Under the Credit Agreement, the Company must not permit (a) consolidated tangible net worth as at the last day of each fiscal quarter of the Company to be less than the sum of (i) $2,019.6 million, (ii) 25% of consolidated net income during the period from January 1, 2021 to and including such last day of such fiscal quarter (if positive) and (iii) 25% of the aggregate net cash proceeds of all issuances by the Company of shares of its capital stock during the period from January 1, 2021 to and including such last day of such fiscal quarter, but excluding (x) any amount included in the Company's accumulated other comprehensive income or loss related to unrealized gains or losses on available for sale securities and (y) during the period from January 1, 2022, any amount included in net unrealized investment gains or losses, related to unrealized gains or losses on trading securities, (b) the ratio of its total consolidated debt to the sum of such debt plus our consolidated tangible net worth to exceed 35% as at the last day of any fiscal quarter of the Company or (c) any material insurance subsidiary to have a financial strength rating of less than "B++" from A.M. Best. The Credit Agreement contains other customary affirmative and negative covenants, including (subject to various exceptions) restrictions on the ability of the Company and its subsidiaries to incur indebtedness, create or permit liens on their assets, engage in mergers or consolidations, dispose of assets, pay dividends or other distributions, purchase or redeem the Company's equity securities, make investments and enter into transactions with affiliates. In addition, the Credit Agreement has customary events of default, including (subject to certain materiality thresholds and grace periods) payment default, failure to comply with covenants, material inaccuracy of representation or warranty, bankruptcy or insolvency proceedings, change of control and cross-default to other debt agreements.

In connection with the Merger, the Company obtained waivers and consents, to the extent required, from its banking partners, to ensure the continuity of its various financing and capital arrangements through the effective time of the Merger in the ordinary course. The Company maintains strong relationships with its banking partners.

*Other Credit Facilities.* 

&nbsp;&nbsp;&nbsp;&nbsp;(i)&nbsp;&nbsp;&nbsp;&nbsp;On February 7, 2019, Aspen European Holdings Limited ("Aspen European") and Aspen Holdings (acting as guarantor of Aspen European) entered into a letter of credit facility for the purpose of obtaining a letter of credit in favor of Aspen UK for a sum not to exceed $100.0 million to provide approved regulatory capital for Aspen UK. A letter of credit was issued in favor of Aspen UK for a sum of $100.0 million. This facility was amended and restated with effect from February 7, 2023, pursuant to which the $100.0 million letter of credit was extended to February 11, 2027.

&nbsp;&nbsp;&nbsp;&nbsp;(ii)&nbsp;&nbsp;&nbsp;&nbsp;On October 31, 2024 AUL and Aspen Holdings (acting as guarantor of AUL), effected an amendment to a letter of credit facility agreement for the account of AUL, pursuant to which a syndicate of lenders issued several letters of credit in an aggregate amount of $430.0 million, for the benefit of Lloyd's, to support AUL's Funds at Lloyd's requirements in connection with the 2025 year of account at Lloyd's.

This further amended the letter of credit facility agreement, dated November 1, 2021, entered into between AUL, Aspen Holdings (acting as guarantor of AUL) and various lenders, for the account of AUL, pursuant to which a lender provided a maximum aggregate amount of $235.0 million, to support AUL's Funds at Lloyd's requirements in connection with the 2021 year of account at Lloyd's, as amended on May 6, 2022, October 27, 2022, October 24, 2023 and April 29, 2024 in connection with the 2021, 2022 and 2023 underwriting years of account at Lloyd's, as applicable.

&nbsp;&nbsp;&nbsp;&nbsp;(iii)&nbsp;&nbsp;&nbsp;&nbsp;On October 31, 2024, AUL and Aspen Holdings (acting as guarantor of AUL) amended a Funds at Lloyd's Facility Agreement dated November 25, 2020, as amended on December 2, 2021, December 1, 2022, and as further amended on November 30, 2023, for the account of AUL.

&nbsp;&nbsp;&nbsp;&nbsp;(iv)&nbsp;&nbsp;&nbsp;&nbsp;On October 31, 2024, AUL and Aspen Holdings (acting as guarantor of AUL) entered into a Funds at Lloyd's Facility, for the account of AUL.

&nbsp;&nbsp;&nbsp;&nbsp;(v)&nbsp;&nbsp;&nbsp;&nbsp;On April 1, 2021, the Company's subsidiaries, AAIC and Aspen Specialty, each established a secured line of credit at Federal Home Loan Bank of Boston ("FHLBB"). Advances may be used to support general corporate purposes. The maximum amount available under these facilities will vary based on the borrower's net admitted assets or reserve assets (total invested assets) and the lender's underwriting criteria. Aspen Specialty's maximum borrowing capacity available from FHLBB upon initial application is 15% of net admitted assets or approximately $269 million, and is subject to North Dakota approval. Under Texas state insurance law, without the prior consent of the Texas Department of Insurance, the amount of assets AAIC may pledge to secure debt obligations is limited to 10% of its reserve assets, resulting in a maximum borrowing capacity for AAIC under its FHLBB facility of approximately $230 million. Neither AAIC nor Aspen Specialty expects to draw on these facilities in the near future.

Advances may be used to support general corporate purposes. As of December 31, 2025, no active repurchase agreement has been entered with either of the banks.

The above credit facilities include certain restrictive covenants customary for facilities of this type, including restrictions on indebtedness, consolidated tangible net worth, and minimum financial strength ratings, with such financial covenants largely consistent with these set forth in the Credit Agreement. In addition, the agreements include default covenants, which could require the Company to fully secure the outstanding amounts thereunder and/or result in the Company not being allowed to issue any new letters of credit.

The Company has recorded the long-term debt at amortized cost in the consolidated balance sheet.

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

**To the Shareholders and the Board of Directors of Aspen Insurance Holdings Limited**

**Opinion on the Financial Statements** 

We have audited the accompanying consolidated balance sheets of Aspen Insurance Holdings Limited (the Company) as of December 31, 2025 and 2024, the related consolidated statements of operations and other comprehensive income, consolidated statements of changes in shareholders' equity and consolidated statements of cash flows for each of the two years in the period ended December 31, 2025, and the related notes and financial statement schedules I to V (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated March 30, 2026 expressed an adverse opinion thereon.

**Basis for Opinion** 

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matters** 

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

| | ***Valuation of Incurred but not Reported Reserve Estimates, Gross and Net of Reinsurance*** |
| *Description of the Matter* | At December 31, 2025, the Company's reserves for losses and loss adjustment expenses, net of reinsurance, was $4,443.1 million, of which a significant proportion is incurred but not reported reserves ('IBNR'). As described in Notes 2(b) and 10 of the consolidated financial statements, losses and loss adjustment expenses represents management's estimate of the ultimate costs of all reported and unreported losses incurred through the balance sheet date. There is significant uncertainty inherent in estimating the IBNR, gross and net of reinsurance. In particular, management's estimate is sensitive to the actuarial methods selected and the significant assumptions applied, including the impact of catastrophe events and other large losses, reinsurance assumptions incorporated into net loss ratios, expected trends in claims severity and frequency, and expected duration of the respective claim's development period.<br>Auditing management's estimate for IBNR reserve estimates, gross and net of reinsurance, was complex and required the involvement of our actuarial specialists, due to the sensitivity of the estimate to the actuarial methods selected and the judgmental nature of the significant assumptions used in the valuation of the estimate, including the netting of IBNR for reinsurance. <br>In addition, our audit required increased effort and judgment due to the nature of the underlying claims data used in the estimation process. As described in Management's Report on Internal Control over Financial Reporting, deficiencies existed in transaction-level controls over the input of financial and non-financial claims data. |
| *How We Addressed the Matter in Our Audit* | To assess the actuarial methodologies applied, with the assistance of our actuarial specialists, we compared management's methods to those used in the industry for similar lines of business. To evaluate the significant assumptions used in the Company's estimates, with the assistance of our actuarial specialists, our procedures included, among others, comparing the significant assumptions, such as incurred to ultimate loss ratios, and industry loss levels specifically for the catastrophe events and other large losses, expected trends in claims severity and frequency and expected duration of the respective claim's development period, as well as reinsurance assumptions, to current industry benchmarks, compiled from information in the public domain, as well as those we have developed internally, from our experience with businesses in the same industry as the Company. Our procedures also included using the Company's historical data to develop our own independent projections and a range of reserve estimates for selected classes of business. We compared our independent projections and range of reserve estimates to the Company's recorded losses and loss adjustment expense reserves, both gross and net of reinsurance. <br>As a result of the material weakness, we increased the extent of our procedures to test the accuracy of the underlying claims information through financial and non-financial data attribute testing which compared the information to third-party source data. |
|  | ***Valuation of Privately–Held Investments*** |
| *Description of the Matter* | At December 31, 2025, the fair value of the Company's privately-held investments totaled $172.3 million of which $133.3 million are based on discounted cash flow models as discussed in Note 6 to the consolidated financial statements. The discount rates used by management in the cash flow models are significant unobservable inputs, which create greater subjectivity when determining the fair value of these investments.<br>Auditing the fair value of the privately-held investments was challenging, due to the judgmental nature of the inputs and assumptions used, including discount rates and timing of cash flows, as these were not directly observable in the market. |
| *How We Addressed the Matter in Our Audit* | To test the fair value estimates, among other procedures, we involved our valuation specialists to independently determine a range of fair values for a sample of securities, which we compared to management's estimates of fair value for the selected securities. In developing our independent estimates, we, together with our valuation specialists, compared management's assumptions such as discount rates, as well as timing of cashflows, to comparable publicly available market information, comparable instruments and other valuation techniques, if available. We also compared the fair value of the privately-held investments to independent third-party vendor pricing, where available. |

**REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

**To the Shareholders and the Board of Directors of Aspen Insurance Holdings Limited**

**Opinion on Internal Control Over Financial Reporting** 

We have audited Aspen Insurance Holdings Limited's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, because of the effect of the material weakness described below on the achievement of the objectives of the control criteria, Aspen Insurance Holdings Limited (the Company) has not maintained effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

A material weakness is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company's annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management's assessment. Management identified a material weakness in the design and operating effectiveness of existing internal controls within its process level controls over its Claims function. The material weakness was a result of deficiencies in the design and operation of transaction-level internal controls over the input of financial and non-financial claims data.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets as of December 31, 2025 and 2024, the related consolidated statements of operations and other comprehensive income, consolidated statements of changes in shareholders' equity and consolidated statements of cash flows for each of the two years in the period ended December 31, 2025, and the related notes and financial statement schedules I to V. This material weakness was considered in determining the nature, timing and extent of audit tests applied in our audit of the 2025 consolidated financial statements, and this report does not affect our report dated March 30, 2026, which expressed an unqualified opinion thereon.

**Basis for Opinion**

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**REPORT OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

**To the Shareholders and the Board of Directors of Aspen Insurance Holdings Limited**

**Opinion on the Financial Statements**

We have audited the consolidated statement of operations and other comprehensive income (loss), changes in shareholders' equity and cash flows of Aspen Insurance Holdings Limited (the Company) for the year ended December 31, 2023, and the related notes and financial statement schedules I to V (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the results of the Company's operations and its cash flows for the year ended December 31, 2023, in conformity with U.S. generally accepted accounting principles.

**Basis for Opinion** 

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

**1. INTRODUCTION**

The purpose of the Insider Trading Policy (the "Policy") is to set out the policy and framework for the safe-keeping of any proprietary, material, or price sensitive non-public information of Aspen Insurance Holdings Limited ("AIHL") and/or any of its subsidiaries (collectively, "Aspen" or the "Group").

If any director, officer, employee, contractor or consultant of Aspen (each, a "Covered Individual") has material non-public information relating to Aspen or its securities (referred to as "Inside Information"), it is a serious violation of U.S. federal and state securities laws, and this Policy, for that Covered Individual or any immediate family member (as described in Clause 2.4 below) of that Covered Individual to (i) buy or, sell, or gift Aspen Securities, or cause the same, (ii) engage in any other action to take advantage of such Inside Information or (iii) disclose the Inside Information to others so that they may trade in Aspen Securities. Such activities may also violate the laws of Bermuda, the United Kingdom or any other relevant jurisdiction, to the extent applicable to Covered Individuals.

This Policy sets forth restrictions and other principles applicable to all Covered Individuals, as well as additional trading restrictions applicable to Designated Individuals (*defined below*).

This Policy also applies to material, non-public information relating to any other company with publicly listed securities with which Aspen does business or is connected, such as Aspen's insureds or shareholders.

Transactions that may be necessary or justifiable for independent reasons do not constitute an exception. Covered Individuals must avoid even the appearance of any improper transactions to preserve Aspen's reputation for adhering to the highest standards of conduct.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**1.1.Ownership, Approval and Periodic Review**

This Policy is owned by the Group General Counsel and will be reviewed periodically and updated as necessary by the Office of the Group General Counsel. Proposed material changes to the Policy shall be approved by the Board of Directors of AIHL. This Policy is applicable to the Group.

**2. BACKGROUND AND SCOPE**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.1.Material Information**

------

Material information is any information that a *reasonable* investor would consider important, as part of the total mix of available information, in a decision to buy, hold or sell shares -- in short, *any information which could reasonably affect the price of the shares*, whether positive or negative.

The following types of information ordinarily would be considered "material." This list is intended to be illustrative only and is not an exhaustive list of material information.

1. Corporate acquisitions, dispositions, or other business combinations;

2. Financial performance, especially quarterly and year-end earnings (and projections of future earnings or losses), and significant changes in financial performance or liquidity;

3. Changes in corporate strategy or objectives;

4. Take-over bids or bids to buy back the common shares of Aspen (including tender offers);

5. Changes in share ownership that may affect control of Aspen;

6. Changes in management;

7. New material insurance or reinsurance contracts or the loss thereof;

8. Changes in reserve levels or practices;

9. Ability of our retrocessionaires to pay receivables to us;

10. Public or private issue of additional securities/debt offerings;

11. Changes in capital structure (including share splits);

12. Additional borrowings of funds;

13. Events of default under financings or other agreements;

14. Development of circumstances affecting Aspen's insurance or reinsurance market;

15. Actual or threatened major litigation or the resolution of such litigation;

16. Significant changes in operating or financial circumstances, such as cash-flow changes, liquidity changes or investment asset impairments;

17. The declaration of dividends or a change in the dividend policy of Aspen;

18. Aspen projections;

19. Significant pricing changes; or

20. Significant new ventures with other insurance or reinsurance companies;

21. Significant cybersecurity incidents; or

22. The gain or loss of a major customer or counterparty

Material information is not to limited to historical facts but may also include projections and forecasts and future events, even if the possibility of that projection, forecast or event occurring is small.

When in doubt about whether particular non-public information is material, you should presume it is material. If you are unsure whether information is material, you should consult with the Office of the Group General Counsel.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.2.Non-Public Information**

Non-public information is any information that has not been disclosed to, and assimilated by, the market. Information about Aspen that is not yet in general circulation should be considered non-public. All information that you learn about Aspen, as a result of, or in connection with, your position or employment is potentially Inside Information until publicly disclosed by Aspen. Information is considered to be assimilated by the market after at least one full Trading Day (*defined below*) has passed since the information was generally disclosed.

All non-public information should be treated as confidential and proprietary to Aspen, and may not be disclosed to others except for legitimate business reasons. Covered Individuals in possession of non-public information that is also material, as discussed in Clause 2.1 above, are required by law and this Policy not to trade in Aspen Securities and not to disclose the information to others.

Note that the fact that information has been disclosed to a few members of the public (for example, banking partners under a non-disclosure agreement) does not make it public for insider trading purposes. Non-public information may include, by way of illustration only:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)Information available to a select group of analysts or brokers or institutional investors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)undisclosed facts that are the subject of rumors, even if the rumors are widely circulated; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)information that has been entrusted to the Company on a confidential basis until a public announcement of the information has been made and enough time has elapsed for the market to respond to a public announcement of the information.

As with questions of materiality, if you are not sure whether information is considered public, you should either consult with the Office of the Group General Counsel or assume that the information is non-public and treat it as confidential.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.3.Hindsight**

If a Covered Individual's transaction in Aspen Securities becomes the subject of scrutiny, it will be viewed after-the-fact with the benefit of hindsight. As a result, before engaging in any transaction involving Aspen Securities, Covered Individuals should carefully consider how others might view such transaction in hindsight.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**2.4.Transactions by Immediate Family Members**

------

The restrictions on trading with Inside Information also apply to the immediate family members of Covered Individuals, which includes the person's spouse, parents, siblings, mothers and fathers-in-law, sons and daughters-in-law, brothers and sisters-in-law, children (including those who are minors or dependents), any other persons who live in the Covered Individual's household, any persons who normally share the Covered Individual's household but have temporarily moved away, and any family members who do not live in their household but whose transactions in Aspen Securities are directed by Covered Individuals or are subject to their influence or control (such as parents or children who consult with Covered Individuals before they transact in Aspen Securities). In addition, these restrictions apply to any entity over which the Covered Individual or any immediate family member exercises or shares investment control (such as a partnership or family trust).

Covered Individuals are responsible for their immediate family members' compliance with this Policy.

**3. POLICY & PRINCIPLES**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.1.Prohibitions on Trading Securities**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1.1.<u>Prohibited Transactions in Aspen Securities</u>

Aspen has preference shares and Class A ordinary shares listed on the New York Stock Exchange (together with any other securities issued by Aspen, the "Aspen Securities") which may be purchased or sold in accordance with this Policy. Covered Individuals are prohibited from engaging in any of the listed activities with respect to the Securities. For the avoidance of doubt, note that the term "Securities" includes options, warrants and other securities that Aspen may issue (including, without limitation and by way of illustration only, notes, debt and convertible securities, and derivative securities relating to Aspen Securities, whether or not issue issued by Aspen).

*3.1.1.1 No Trading While in Possession of Inside Information*

No Covered Individual in possession of Inside Information concerning Aspen may trade in Aspen Securities, even if such trades occur outside any Close Periods (as defined and described further in Clause 3.1.2 below), other than pursuant to a properly qualified, adopted and submitted Rule 10b5-1 trading plan or similar trading plan as defined and described further in Clause 3.1.4 below). Once such information becomes publicly available, a Covered Individual may only trade in Aspen Securities after one full Trading Day. For purposes of this Policy, a "Trading Day" shall mean any day on which the New York Stock Exchange is

------

open for trading. Additionally, Aspen itself will not trade in Aspen Securities in violation of applicable securities laws or stock exchange listing standards.

*3.1.1.2 Tipping Aspen Inside Information to Others*

Covered Individuals shall not disclose Inside Information to others, including family members and relatives, (either explicitly, implicitly or by way of generally advising others to buy or sell Aspen Securities while in possession of such information) unless required as part of that Covered Individual's regular duties for Aspen, and authorized by at least one of the Chief Executive Officer, Group President, Chief Financial Officer or Group General Counsel. The penalties discussed below apply whether or not the Covered Individual derives any benefit from another's actions after receiving such information.

Simply put, you should never trade, tip or recommend securities (or otherwise cause the purchase or sale of securities) while in possession of information that you have reason to believe is material and non-public unless you first obtain the advance approval of one of the individuals noted above. If in doubt, please consult with the Office of the Group General Counsel.

*3.1.1.3 Hedging Transactions – Buying or Selling Puts or Calls*

Covered Individuals may not enter into hedging or monetization transactions or similar arrangements with respect to Aspen Securities. Accordingly, the purchase or sale of options for Aspen's Securities of any kind, whether puts or calls<sup>1</sup>, shall not be permitted.

*3.1.1.4 Hedging Transactions – Short Sales*

No Covered Individual may engage in short sales<sup>2</sup>.

*3.1.1.5 Trading in Securities on a Short-Term Basis*

In relation to any AIHL director or executive officer or the principal accounting officer or such other individual as may be designated by the Group General Counsel, in their discretion (each, a "Designated Individual")<sup>3</sup>, any Aspen Securities purchased in the open market should be held for a minimum of six (6)

<sup>1</sup> A <u>put</u> is a right to sell at a specified price a specific number of shares by a certain date and is utilized in anticipation of a decline in the share price. A <u>call</u> is a right to buy at a specific price a specified number of shares by a certain date and is utilized in anticipation of a rise in the share price.

<sup>2</sup> Selling short is the practice of selling more shares than one owns to speculate on a decline in the share price.

<sup>3</sup> The Group General Counsel maintains a list of current executive officers and Designated Individuals

------

months and may not be sold in violation of the prohibition on short-swing trading<sup>4</sup>. While the requirement against trading in securities on a short-term basis applies to Aspen in all circumstances, the short-swing trading rule does not apply to transactions during such time as Aspen is a foreign private issuer under the U.S. securities laws.

*3.1.1.6 Trading on margin or pledging*

Covered Individuals may not hold Aspen Securities in a margin account or pledge Aspen Securities as collateral.

*3.1.1.7 Trading in Other Securities*

No Covered Individual may (a) trade or gift in securities of any public company while in possession of Inside Information concerning that company, unless such trade or gift is made pursuant to a properly qualified, adopted and submitted Rule 10b5-1 trading plan, (b) "tip" or disclose Inside Information concerning any public company to any other person, including family members and relatives, so that they may trade in the securities of that company or (c) give trading advice to anyone, including family members and relatives, concerning any public company if such Covered Individual possesses Inside Information about that company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1.2.<u>Close Periods</u>

*3.1.2.1 General*

Save as otherwise provided for in this Policy, Covered Individuals are permitted to trade in Aspen Securities when no close period is in effect, as described in this Clause 3.1.2.

However, even during this open trading window, a Covered Individual who is in possession of any Inside Information should not trade in Aspen Securities until the information has been made publicly available or is no longer material. In addition, the Company may close this trading window if a special close period, as described in this Clause 3.1.2, is imposed and will re-open the trading window once the special close period has ended.

*3.1.2.2 Quarterly Close Periods*

<sup>4</sup> See Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act") See Section 16(b) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), which establishes mechanisms for a company to recover "short swing" profits, or profits an insider realizes from a purchase and sale of the company's security that occur within a six-month period

------

Covered Individuals and their immediate family members shall be subject to quarterly close periods during which they are prohibited from conducting any transactions involving Aspen Securities. Each quarterly close period shall commence on the 14th day of the month in which a quarter ends (i.e. March 14, June 14, September 14 and December 14), and shall end one (1) full trading day after the date that Aspen publicly announces its quarterly and/or annual earnings (the "Quarterly Close Period")<sup>5</sup>. It is improper for a Covered Individual to enter into a securities trade immediately after Aspen has publicly announced its quarterly and/or annual earnings because Aspen's shareholders and the public should be given sufficient time to receive the information and act upon it.

During these quarterly close periods, Covered Individuals are presumed to possess Inside Information about the Company's financial results.

Notwithstanding the foregoing, a transaction may be exempt from the Quarterly Close Period if it is made pursuant to an Approved 10b5-1 Plan (*defined below*). See Clause 3.1.4 below for more information on Rule 10b5-1 trading plans.

*3.1.2.3 Special Close Periods*

In addition to the Quarterly Close Period, a special close period may be imposed at other times on Designated Individuals, or a subset thereof, such as during the pendency of certain Aspen transactions or when some other extraordinary Aspen event is pending ("Special Close Period").

A Designated Individual shall receive written notice when a Special Close Period applies to them. A Special Close Period will remain in effect until such Designated Individual shall receive a written notice that the Special Close Period has ended. Designated Individuals subject to the Special Close Period shall be prohibited from disclosing to any person the existence of any such Special Close Period and may be required to sign a confidentiality agreement.

A transaction may be exempt from the Special Close Period if it is made pursuant to an Approved 10b5-1 Plan (*defined below*). See Clause 3.1.4 below for more information on Rule 10b5-1 trading plans.

*3.1.2.4&nbsp;&nbsp;&nbsp;&nbsp;Designated Individuals*

At all times, transactions in Aspen Securities are prohibited for Designated Individuals, unless such trades are pre-cleared (see further below in Section 3.2). Pre-clearance will not be provided during the duration of any Special Close Period. For the avoidance of doubt, Designated Individuals shall include those

<sup>5</sup> For example, if Aspen issues a quarterly set of financial results (or associated press release) on a Tuesday (after the US trading market closes), then the Covered Individuals shall not be permitted to trade in Aspen securities until the market opens on Thursday (as Wednesday would be the first full trading day following the release)

------

individuals determined by the Group General Counsel to constitute "affiliates" for the purposes of the U.S. securities laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1.3.<u>Hardship Cases</u>

Aspen will not grant any exceptions to the restriction against trading in Aspen Securities during any Quarterly Close Period or Special Close Period even if the Covered Individuals subject to such close periods (or Designated Individuals, for Special Close Periods) may find it necessary or justifiable for independent reasons (such as the need to raise money for an emergency expenditure) to trade in Aspen Securities at impermissible times.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1.4.<u>Rule 10b5-1 Trading Plans</u>

Rule 10b5-1 under the Exchange Act provides an affirmative defense against a claim of insider trading if an insider's trades are made pursuant to a written plan that was adopted in good faith at a time when the insider was not aware of Inside Information and that complies with all applicable requirements of Rule 10b5-1 (an "Approved 10b5-1 Plan"). A Covered Individual may make trades or gifts pursuant to an Approved 10b5-1 Plan provided that (i) such plan meets the requirements of Rule 10b5-1, (ii) such plan was adopted at a time when the Covered Individual would otherwise have been able to trade under this Policy; (iii) with respect to Designated Individuals, adoption of the plan was expressly authorized in writing in advance by the Group General Counsel and (iv) the plan was adopted in good faith and not as part of a scheme or plan to evade the prohibitions of Rule 10b5-1.

Once the plan is adopted, the insider must not exercise any influence over the amount of securities to be traded, the price at which they are to be traded or the date of the trade. Pre-clearance of individual trades, as described in Section 3.2, made pursuant to an Approved 10b5-1 Plan is not required. However, note that trades made pursuant to Rule 10b5-1 plans by Designated Individuals must still be reported to the Group General Counsel pursuant to the third paragraph of Section 3.2 below. Additionally, plan modifications are only permitted at a time when the Covered Individual would otherwise have been able to trade under this Policy and must comply with the requirements of Rule 10b5-1, including any new cooling off periods that may apply as a result of such modifications. All plan modifications made by Designated Individuals must be expressly authorized in writing in advance by the Group General Counsel. Insiders must also report any termination of a Rule 10b5-1 plan to the Group General Counsel within one business day of such termination. A Rule 10b5-1 plan should not be terminated during a quarterly close window or a special close window.

------

No 10b5-1 Plan may be adopted or modified during a quarterly or special close period applicable to the person adopting the 10b5-1 Plan (put another way, Covered Individuals may only put in place an Approved 10b5-1 Plan during an open trading window.

If you are considering entering into, modifying or terminating an Approved 10b5-1 Plan or other pre-established trading arrangement or have any questions regarding Approved Rule 10b5-1 Plans or other pre-established trading arrangements, please contact the Office of the Group General Counsel. You should consult your own legal and tax advisors before entering into, or modifying or terminating, an Approved 10b5-1 Plan or other pre-established trading arrangement. A trading plan, contract, instruction or arrangement of a Designated Individual will not qualify as an Approved 10b5-1 Plan and will not be permitted under this Policy without the prior review and approval of the Group General Counsel as described above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1.5.<u>Rule 144</u>

Designated Individuals are required to comply with the restrictions on sales by control persons (including, if applicable, the provisions of the safe harbor set forth in Rule 144 under the Securities Act of 1933, as amended), and should file or cause to be filed any notices of sale required by Rule 144.<sup>6</sup>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.1.6.<u>Exceptions</u>

*3.1.4.1 401(k) Plan*

Investing 401(k) plan contributions in Securities in accordance with the terms of the Company's 401(k) plan, where applicable, is permitted. However, any changes in your investment election regarding Aspen Securities are subject to trading restrictions under this Policy.

*3.1.4.2 Employee Share Purchase Plan*

Purchasing Securities through any Company equity programs in place from time to time is permitted. However, both at the point of initially establishing the plan and when making changes thereto, you are subject to the trading restrictions under this Policy.

<sup>6</sup> Note that Form 144 relating to transactions using the Rule 144 safe harbor must be filed on or before the trade date. It's an obligation of the individual and is typically handled by brokers. Where required, the filing of Form 144 is a necessary component of reliance on the Rule 144 safe harbor. Where assistance is required, please contact the Group General Counsel.

------

*3.1.4.3 Options*

Exercising share options granted under Aspen's Equity Incentive Plan for cash or the delivery by the Company of Securities is permitted. However, the sale of any shares issued on the exercise of Company-granted share options and any cashless exercise of Company-granted share options are subject to trading restrictions under this Policy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**3.2.Procedures for Submitting Trades by Designated Individuals**

No Designated Individual shall trade in Aspen Securities without first submitting the following signed appendices to (i) the Group General Counsel and (ii) the Group Head of Reward, Operations & Governance at least two (2) business days prior to the proposed trade(s):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• <u>Appendix A</u> attached hereto, whereby the Designated Individual acknowledges and agrees that they have read and understood this Policy and will comply with its terms;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• <u>Appendix B</u> attached hereto, whereby the Designated Individual lists the details of the proposed trade(s), including the type and amount of securities such Designated Individual proposes to trade; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• <u>Appendix C</u> attached hereto, whereby the Designated Individual certifies that (i) he or she is not in possession of Inside Information concerning Aspen, (ii) the proposed trade(s) does not violate the trading restrictions of Rule 10b-5 of the Exchange Act or any other applicable laws or regulations, and (iii) the proposed trade(s) complies and will comply with all applicable provisions of Rule 144 under the Securities Act of 1933, as amended (the "Securities Act"), or any other exemption, safe harbor, or affirmative defense upon which the Designated Individual intends to rely in connection with the proposed trade(s).

If the Designated Individual has any doubt as to whether they have Inside Information, they shall consult with the Office of the Group General Counsel prior to signing the appendices described above.

Once approved, the Designated Individual must complete the trade within five (5) business days of the proposed trade date, subject to any Special Close Period, if applicable, as detailed in Clause 3.1.2. The proposed trade date must likewise not fall within a Quarterly Close Period as detailed in Clause 3.1.2. If the Designated Individual has not completed the trade within five (5) business days of the proposed trade date, such Designated Individual shall resubmit all of the appendices above prior to executing such trade. Aspen requires that all

------

Designated Individuals submit to the Group General Counsel a copy of any trade order or confirmation relating to the purchase, sale or gift of Aspen securities within two business days of any such transaction. This information is necessary to enable us to monitor trading by executive officers and directors and ensure that all such trades are properly reported.

For the avoidance of doubt, if the Designated Individual obtains material non-public information about Aspen subsequent to signing the appendices described above, the Designated Individual shall not engage in the proposed trade(s) as doing so would violate U.S. federal and state securities laws and this Policy.

The Group General Counsel shall record the date each request is received and the date and time each request is approved or disapproved.

**4. VIOLATIONS & REPORTING**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.1.Consequences of Violations**

The consequences of insider trading violations under U.S. securities laws can be severe.

Individuals who trade on the basis of inside information (or tip inside information to others) may be subject to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a civil penalty of up to three times the profit gained or loss avoided;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ban from serving as an officer or director of a public company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a criminal fine (no matter how small the profit); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• imprisonment.

For a company (as well as any supervisory person) that fails to take appropriate steps to prevent illegal trading, the following consequences may arise:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a civil penalty; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a criminal penalty.

Moreover, if a Covered Individual violates this Policy, company-imposed sanctions, including dismissal for cause, could result from failing to comply with the policy or procedures. Any of the above consequences, including an SEC investigation that does not result in prosecution, can tarnish one's reputation and irreparably damage a career.

Sanctions under the laws of the United Kingdom and/or Bermuda may also apply.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**4.2.Reporting of Violations**

Any Covered Individual who violates this Policy or any U.S. federal or state laws governing insider trading or tipping, or knows of any violation(s) by other Covered Individuals, must immediately report such violation(s) to the Office of the Group General Counsel. The Group General Counsel then will consult with the Chair of AIHL's Audit Committee to determine Aspen's actions in response to any such violation(s), which may include reporting to the SEC or other appropriate authority (such as the New York Stock Exchange).

**5. ASSISTANCE & CERTIFICATIONS**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**5.1.Company Assistance**

Any person who has any questions about specific transactions may obtain additional guidance from the Office of the Group General Counsel. However, the ultimate responsibility for adhering to this Policy and avoiding improper transactions rests with each Covered Individual. As a result, it is imperative that Covered Individuals use their best judgment when complying with this Policy.
