ITEM 1. BUSINESS

Overview

Assured Guaranty Ltd. (AGL and, together with its subsidiaries, Assured Guaranty or the Company) is a Bermuda-based holding company that provides, through its wholly-owned operating subsidiaries, credit protection products to the U.S. and non-U.S. public finance (including infrastructure) and structured finance markets. Assured Guaranty also participates in the asset management business.

Through its financial guaranty insurance subsidiaries, the Company applies its credit underwriting judgment, risk management skills and capital markets experience primarily to offer financial guaranty insurance, including nonpayment insurance, that protects holders of debt instruments and other monetary obligations from defaults in scheduled payments. If an obligor defaults on a scheduled payment due on an obligation, such as scheduled principal or interest payment (collectively, debt service), the Company is required under its unconditional and irrevocable financial guaranty to pay the shortfall of the scheduled amount to the holder of the obligation, but generally cannot be required by the holder to pay on an accelerated basis. The Company markets its financial guaranty insurance directly to issuers and underwriters of public finance and structured finance securities as well as to investors in such obligations. The Company guarantees obligations issued principally in the U.S. and the United Kingdom (U.K.), and also guarantees obligations issued in other countries and regions, including Western Europe and Australia. The Company also provides specialty insurance and reinsurance on transactions with risk profiles similar to those of its structured finance exposures written in financial guaranty form.

The Company participates in the asset management business through its ownership interest in Sound Point Capital Management, LP (Sound Point, LP) and certain of its investment management affiliates (together with Sound Point, LP, Sound Point), as described in greater detail under Item 1. Business — Asset Management.

On January 21, 2026, the Company purchased all of the outstanding share capital in Warwick Company (UK) Limited (which is the 100% indirect owner of Assured Life Reinsurance Ltd. (Assured Life Re, f/k/a Warwick Re Limited), for a purchase price of $158 million, subject to certain post-closing adjustments (Assured Life Re Acquisition). Assured Life Re is a Class E long-term (life) reinsurance company incorporated and registered in Bermuda and is rated BBB (Outlook Positive) (1/28/26) by Fitch Ratings, Inc. Assured Life Re focuses on annuity reinsurance including U.K. bulk purchase annuity (pension risk transfers) and U.S. multi-year guaranteed annuity transactions. The Assured Life Re Acquisition represents the Company's first platform dedicated solely to the life and annuity reinsurance business, further diversifying the risk profile and revenue opportunities of the Company.

See Item 1A. Risk Factors — Strategic Risks, captioned “The Assured Life Re Acquisition may negatively impact the Company, including how it is perceived by its investors, regulators, rating agencies or obligors it insures, as well as Assured Life Re’s business relationships,” “Entering the life and annuity reinsurance business may present integration risks and other risks specific to the life and annuity reinsurance business that could have a negative effect on the Company's business, results of operations or financial condition,” “Strategic transactions may not result in the benefits anticipated” and “The Company makes assumptions when pricing its life and annuity reinsurance products relating to longevity, mortality, policy lapses, withdrawals, surrenders, investment returns and expenses, and significant deviations in experience could negatively affect the Company’s financial condition and results of operations.”

The Company continually evaluates its key business strategies, which fall into four areas: (i) growth of its insurance and asset management businesses; (ii) loss mitigation, (iii) enhancement of investment returns through alternative investments; and (iv) capital management. The Company seeks to grow its core financial guaranty insurance business through new business production in established sectors and jurisdictions and by entering into new markets, lines and classes of business, and also through acquisitions of financial guarantors that are no longer actively writing new business (legacy financial guarantors) or their insured portfolios through reinsurance or novations. In addition, the Company seeks to leverage its core credit competencies by expanding its business into revenue streams independent of its financial guaranty insurance business, such as annuity reinsurance through its life and annuity reinsurance platform and its asset management business, with the objective of diversifying net income growth and generating high-return business opportunities. The Company also employs a number of strategies in an effort to mitigate losses in its insured portfolio. The Company seeks to optimize its investment returns and expects its relationship with Sound Point to enhance alternative investment opportunities for its insurance subsidiaries. Finally, the Company pursues strategies to efficiently allocate and utilize capital within the Assured Guaranty group.

Insurance

Insurance Business

Financial Guaranty

Financial guaranty insurance generally provides an unconditional and irrevocable guaranty that protects the holder of a debt instrument or other monetary obligation against non-payment of debt service when due. Upon an obligor’s default on scheduled payments due on the debt obligation, whether due to its insolvency or otherwise, the Company is generally required under the financial guaranty contract to pay the investor the principal and interest shortfalls when due.

Financial guaranty insurance may be issued to all of the investors of the guaranteed series or tranche of a municipal bond or structured finance loan or other debt obligation at the time of issuance or it may be issued to specific individual holders of such obligations who purchase the Company’s credit protection either in the secondary market or on a bilateral basis where the borrower has purchased the financial guaranty to benefit its own obligations.

Both issuers of, and investors in, financial instruments may benefit from financial guaranty insurance. Issuers benefit when they purchase financial guaranty insurance for their new issue debt transaction because the insurance may have the effect of lowering an issuer’s interest cost over the life of the debt transaction to the extent that the insurance premium charged by the Company is less than the net present value of the difference between the yield on the obligation insured by Assured Guaranty (which carries the credit rating of the specific subsidiary that guarantees the debt obligation) and the yield on the debt obligation if sold on the basis of its uninsured credit rating. The principal benefit to investors is that the Company's financial guaranty provides increased certainty that scheduled payments will be received when due. The Company’s financial guaranty of bank loans may also provide policyholders with reduced regulatory capital requirements or relief from internally managed credit limits. Additionally, financial guaranty insurance may improve the marketability and liquidity of obligations, especially obligations with complex structures or backed by asset classes new to the market. In general, and especially in such instances, investors may be able to sell insured bonds more quickly and at a better price than the comparable uninsured debt.

As an alternative to traditional financial guaranty insurance, the Company also may provide credit protection relating to a particular debt obligation or obligor through a credit derivative contract, such as a credit default swap (CDS). Under the terms of a CDS, the provider of credit protection agrees to make a specified payment to the buyer of credit protection if one or more specified credit events occurs with respect to a reference obligation or entity. In general, the Company’s CDS provide that failure to pay debt service on the reference obligation is a credit event, but the Company’s rights and remedies under a CDS may be different and more limited than under financial guaranty insurance.

The Company also offers credit protection through reinsurance, and in the past has provided reinsurance to other financial guaranty insurers with respect to their financial guaranties of public finance, infrastructure and structured finance obligations. The Company believes that the financial guaranty opportunities currently available to it in the reinsurance market primarily consist of potentially assuming portfolios of transactions from legacy financial guarantors.

U.S. Public Finance Obligations The Company insures and reinsures a number of different types of U.S. public finance obligations. The types of U.S. public finance obligations the Company insures include the following:

General Obligation Bonds are full faith and credit obligations that are issued by states, their political subdivisions and other municipal issuers, and are supported by the general obligation of the issuer to pay from available funds and by a pledge of the issuer to levy property taxes in an amount sufficient to provide for the full payment of the bonds.

Tax-Backed Bonds are obligations that are supported by the issuer from specific and discrete sources of taxation and tax-backed revenue bonds. Tax-backed obligations may be secured by a lien on specific pledged tax revenues, such as a gasoline or excise tax, or an income tax, or incrementally from growth in property tax revenue associated with growth in property values. These obligations also include obligations secured by special assessments levied against property owners and often benefit from issuer covenants to enforce collections of such assessments and to foreclose on delinquent properties. Lease revenue bonds typically are general fund obligations of a municipality or other governmental authority that are subject to annual appropriation or abatement; projects financed and subject to such lease payments ordinarily include real estate or equipment serving an essential public purpose.

Municipal Utility Bonds are obligations of all forms of municipal utilities, including electric, water and sewer utilities and resource recovery revenue bonds. These utilities may be organized in various forms, including municipal enterprise systems, authorities or joint action agencies.

Transportation Bonds include a wide variety of revenue-supported obligations, such as bonds for airports, ports, tunnels, municipal parking facilities, toll roads and toll bridges.

Healthcare Bonds are obligations of healthcare facilities, including community-based hospitals and systems, and hospital districts.

Infrastructure Bonds include obligations issued by a variety of entities engaged in the financing of infrastructure projects, such as roads, airports, ports, military housing, social infrastructure, student accommodation and other physical assets delivering essential services supported by long-term concession arrangements with a public sector entity.

Higher Education Bonds are obligations secured by revenue collected by either public or private secondary schools, colleges and universities. Such revenue can encompass all of an institution’s revenue, including tuition and fees, or in other cases, can be specifically restricted to certain auxiliary sources of revenue or revenue relating to student accommodation.

Renewable Energy Bonds are obligations backed by revenue from renewable energy sources.

Other Public Finance Bonds include other debt issued, guaranteed or otherwise supported by U.S. national or local governmental authorities, as well as student loans, revenue bonds, housing revenue bonds, and obligations of some not-for-profit organizations.

A portion of the Company’s exposure to tax-backed bonds, municipal utility bonds and transportation bonds constitutes “special revenue” bonds under the United States Bankruptcy Code (Bankruptcy Code). Special revenue bonds benefit from a lien on the special revenues, after deducting necessary operating expenses, of the project or system from which the revenues are derived.

Non-U.S. Public Finance Obligations The Company insures and reinsures a number of different types of non-U.S. public finance obligations. The types of non-U.S. public finance securities the Company insures and reinsures include the following:

Regulated Utility Obligations are obligations issued by government-regulated providers of essential services and commodities, including electric, water and gas utilities, supported by the rates and charges paid by the utilities’ customers. The majority of the Company’s non-U.S. regulated utility business is conducted in the U.K.

Infrastructure Finance Obligations are obligations issued by a variety of entities engaged in the financing of non-U.S. infrastructure projects, such as roads, airports, ports, social infrastructure, student accommodation, stadiums, and other physical assets delivering essential services supported either by long-term concession arrangements or a regulatory regime. The majority of the Company’s non-U.S. infrastructure business is conducted in the U.K.

Sovereign and Sub-Sovereign Obligations primarily includes obligations of local, municipal, regional or national governmental authorities or agencies outside of the U.S.

Renewable Energy Bonds are obligations secured by revenues relating to renewable energy sources, typically solar or wind farms. These transactions often benefit from regulatory support in the form of regulated minimum prices for the electricity produced. The majority of the Company’s non-U.S. renewable energy business is conducted in Spain.

Pooled Infrastructure Obligations are synthetic asset-backed obligations that take the form of CDS obligations or credit-linked notes that reference either infrastructure finance obligations or a pool of such obligations, with a defined deductible to cover credit risks associated with the referenced obligations. The Company has not entered into a pooled infrastructure transaction since 2006.

U.S. and Non-U.S. Structured Finance Obligations The Company insures and reinsures a number of different types of U.S. and non-U.S. structured finance obligations. Structured finance counterparties and policy beneficiaries use the Company’s financial guaranty for a variety of reasons, including credit enhancement, risk syndication and regulatory capital optimization. Credit support for the exposures written by the Company may come from a variety of sources, including some combination of subordinated tranches, excess spread, over-collateralization or cash reserves. Additional support also may be

provided by transaction provisions intended to benefit debt holders, investors and lenders. The types of U.S. and non-U.S. structured finance obligations the Company insures and reinsures include the following:

Insurance Reserve Financings and Securitizations are transactions, including life insurance transactions, where obligations are secured by the future earnings from pools of various types of insurance/reinsurance policies and income produced by invested assets.

Residential Mortgage-Backed Securities (RMBS) are obligations backed by first and second lien mortgage loans on residential properties. The credit quality of borrowers covers a broad range, including “prime,” “subprime” and “Alt-A.” A prime borrower is generally defined as one with strong risk characteristics as measured by factors such as payment history, credit score, and debt-to-income ratio. A subprime borrower is a borrower with higher risk characteristics. An Alt-A borrower is generally defined as a prime quality borrower that lacks certain ancillary characteristics, such as fully documented income. RMBS include home equity lines of credit (HELOCs), which refers to a type of residential mortgage-backed transaction backed by second-lien loan collateral. The Company has not provided insurance for RMBS in the primary market since 2008.

Fund Finance Facilities are primarily subscription finance which are credit facilities provided to closed-end private market funds, most frequently private-equity funds. The facilities are secured by the uncalled capital commitments of the limited partners (LPs) to the fund. The Company may guarantee new or existing facilities and on a single facility or portfolio basis. Assured Guaranty’s exposures are generally to facilities with characteristics that include a high-quality fund sponsor with strong historical performance, a diverse LP base composed primarily of institutional LPs and experienced bank lenders.

Pooled Corporate Obligations are securities primarily backed by various types of corporate debt obligations, such as secured or unsecured bonds, bank loans or loan participations and trust preferred securities. These securities are often issued in “tranches,” with subordinated tranches providing credit support to the more senior tranches. The Company’s financial guaranty exposures generally are to the more senior tranches of these issues.

Financial Products is the guarantee of certain business written by financial products companies owned by Dexia SA, which comprised guaranteed investment contracts, medium term notes and equity payment undertaking agreements associated with leveraged lease business. This business is being run off with the final maturity due in 2031. Assured Guaranty is indemnified by Dexia SA and certain of its affiliates against loss from the financial products business.

Other Structured Finance Obligations are obligations backed by assets not generally described in any of the other U.S. and Non-U.S. Structured Finance Obligations categories above.

Specialty Business

The Company also guarantees specialty business with similar risk profiles to its structured finance exposures written in financial guaranty form. Specialty business includes, for example, diversified real estate, insurance reserve financings and securitizations, pooled corporate obligations and aircraft residual value insurance transactions.

Exposure Limits, Underwriting Process, and Credit Policy

Exposure Limits

The Company establishes exposure limits and underwriting criteria for obligors, sectors and countries, and for individual insurance transactions. Risk exposure limits for single obligors are based on the Company’s capital resources and its assessment of potential frequency and severity of loss as well as other factors, such as historical and stressed collateral performance. Moreover, these limits may also be constrained by both regulatory limits or rating agency requirements. Sector limits are based on the Company’s view of stress losses for the sector and on its assessment of correlation. Country limits are based on the size and stability of the relevant economy, and the Company’s view of the political environment and legal system. All of the foregoing limits are established in relation to the Company’s capital base. In certain cases, however, the Company’s ultimate exposure may exceed its underwriting guidelines (caused by, for example, bond accretion exceeding the risk limitation, acquisitions, reassumptions or other strategic exceptions). See Item 1A. Risk Factors — Risks Related to Economic, Market and Political Conditions and Natural Phenomena captioned “The Company may be subjected to significant risks from large individual or correlated financial guaranty insurance exposures.”

Underwriting Process

The underwriting process for each insurance transaction involves underwriters, credit personnel and lawyers who analyze the structure of a potential transaction and the credit and legal issues pertinent to the particular line of business or asset class. Some transactions also involve accounting personnel who review the transactions to determine the appropriate accounting treatment. Formal credit reports for each proposed insurance transaction are assessed and approved by a credit committee composed of senior officers of the Company.

The Company maintains underwriting manuals that articulate the application of the principles in its risk appetite statement to its insurance business. For new business, generally a risk must be viewed by the Company as investment grade at the time of underwriting to be eligible for insurance. The underwriting manuals also articulate the Company’s exposure limits and credit policies applicable to specific products.

U.S. Public Finance. For U.S. public finance transactions, the Company’s underwriters generally analyze the issuer’s historical financial statements and, where warranted, develop stress case projections to test the issuer’s ability to make timely debt service payments under stressful economic conditions.

The Company focuses principally on the credit quality of the obligor based on population size and trends, wealth factors, and strength of the economy. The Company evaluates the obligor’s liquidity position; its fiscal management policies and track record; its ability to raise revenues and control expenses; and its exposure to derivative contracts and to debt subject to acceleration. The Company assesses the obligor’s pension and other post-employment benefits obligations, if applicable, and funding policies and evaluates the obligor’s ability to adequately fund such obligations in the future. The Company analyzes other critical risk factors including the type of issue; the repayment source; pledged security, if any; the presence of restrictive covenants and the tenor of the risk. The Company also considers the ability of obligors to file for bankruptcy or receivership under applicable statutes (and on related statutes that provide for state oversight or fiscal control over financially troubled obligors). The Company evaluates the impact of environmental and climate change risks, including natural perils, on the ability of the obligor to meet its financial obligations over the life of the insured transaction. Such risks may include rising sea levels, hurricanes, wildfires and earthquakes. The Company also assesses resilience measures undertaken by the obligor and the potential availability (or lack thereof) of state and/or federal aid in the event of a natural disaster.

In cases of not-for-profit institutions, such as healthcare issuers and private higher education issuers, the Company focuses on the financial stability of the institution, its competitive position and its management experience, restrictive covenants imposed on the obligor for the benefit of debt holders, and reliance on governmental aid or payments such as Medicaid, Medicare and the Affordable Care Act by healthcare issuers and research grants by higher education issuers.

The Company’s credit policy for U.S. infrastructure transactions is substantially similar to that of non-U.S. infrastructure transactions described below.

Non-U.S. Public Finance Transactions. For non-U.S. transactions, the Company undertakes an analysis of the country or countries in which the risk resides, or in the case of a bilateral agreement, the country where the beneficiary resides, which includes regulatory and political risk as well as economic and demographic characteristics. For each transaction, the Company also performs an assessment of the legal framework governing the transaction and the laws affecting the underlying assets supporting the obligations to be insured.

The underwriting of regulated utilities outside of the U.S. primarily focuses on financial strength of the utility, financial covenants made by the utility, and regulations relevant to the specific jurisdiction. The Company also assesses each transaction for material environmental and climate change risks, and incorporates its assessment into its underwriting decisions.

For non-U.S. infrastructure transactions, the Company reviews the type of project (e.g., utility, hospital, road, social housing, transportation or student accommodation) and the source of repayment of the debt. For certain transactions, debt service and operational expenses are covered by availability payments made by either a governmental or not-for-profit entity. The availability payments are due if the project is available for use, regardless of whether the project actually is in use. The principal risks for such transactions are construction risk and operational risk.

For other transactions, notably transactions secured by toll-roads, student accommodation and stadiums (i.e., assets subject to demand risk), revenues derived from the project must be sufficient to make debt service payments, net of operating expenses, as well as cover the upfront operating expenses it experiences during the build phase before revenues are generated.

For infrastructure transactions, underwriters generally use financial models to evaluate the ability of the transaction to generate adequate cash flow to service the debt under a variety of scenarios. The models include economically stressed scenarios that the underwriters use for their assessment of the potential credit risk inherent in a particular transaction. Stress models developed internally by the Company’s underwriters reflect both empirical research and information gathered from third parties, such as rating agencies, or investment banks or technical advisers. The Company may also engage advisers such as consultants and external counsel to assist in analyzing a transaction’s financial or legal risks.

The Company’s due diligence for infrastructure projects also includes: a financial review of the entity seeking the development of the project (usually a governmental entity or university); a financial and operational review of the developer, the construction companies, and the project operator; and a financial review of the various providers of operational financial protection for the bondholders (and therefore the insurer), including construction surety providers, letter-of-credit providers, and banks. The Company uses outside consultants to review the construction program and to assess whether the project can be completed on time and on budget. The Company projects the cost of replacing the construction company, including delays in construction, in the event that a construction company is unable to complete the construction for any reason. Construction security packages are sized appropriately to cover these risks and the Company requires such coverage from credit-worthy institutions.

U.S. Structured Finance. Structured finance obligations generally present three distinct forms of risk: asset risk, pertaining to the amount and quality of assets underlying an issue; structural risk, pertaining to the extent to which an issuer's legal structure provides protection from loss; and execution risk, which is the risk that poor performance by a servicer or collateral manager contributes to a decline in the cash flow available to the transaction. Each of these risks is addressed through the Company’s underwriting process. The underwriter is also required to assess the presence of any environmental or climate change risk and, to the extent there are notable environmental or climate change risks, analyze the potential impact, if any, of these risks on the transaction over its expected life, and present this assessment to the credit committee.

For structured finance transactions, underwriters generally use financial models to evaluate the ability of the transaction to generate adequate cash flow to service the debt under a variety of hypothetical scenarios. The models include economically stressed scenarios that the underwriters use for their assessment of the potential credit risk inherent in a particular transaction. Stress models developed internally by the Company’s underwriters reflect both empirical research and information gathered from third parties, such as rating agencies or investment banks. Generally, the amount and quality of asset coverage required with respect to a structured finance exposure is dependent upon both the historic performance of the asset class, as well as the Company’s view of the future performance of the subject assets.

The Company may also engage advisers such as consultants and external counsel to assist in analyzing a transaction's financial or legal risks. The Company may also conduct a due diligence review that includes, among other things, a site visit to the project or facility, meetings with issuer management, review of underwriting and operational procedures, file reviews, and review of financial procedures and computer systems.

In addition, structured securities usually are designed to protect investors (and therefore the insurer or reinsurer) from the bankruptcy or insolvency of the entity that originated the underlying assets, as well as the bankruptcy or insolvency of the servicer or manager of those assets.

The Company conducts due diligence on the collateral that supports its insured transactions. The principal focus of the due diligence is to confirm the underlying collateral was originated in accordance with the stated underwriting criteria of the asset originator. The Company also conducts audits of servicing or other management procedures, reviewing critical aspects of these procedures such as cash management and collections. The Company may, for certain transactions, obtain background checks on key managers of the originator, servicer or manager of the obligations underlying that transaction.

Non-U.S. Structured Finance. The underwriting process for Non-U.S. Structured Finance transactions is substantially similar to the procedures described above for U.S. Structured Finance transactions, with additional consideration for the risks relating to the relevant jurisdiction for each transaction.

Importance of Financial Strength Ratings

Financial strength ratings reflect a rating agency’s opinion of an insurer’s ability to pay under its insurance policies and contracts in accordance with their terms. When an insurance subsidiary of the Company guarantees an obligation, the issuer or another party may request that one or more rating agencies providing financial strength ratings on such insurer assign that

insurer’s financial strength rating to the specific obligation it guaranteed. The ability to uplift credit ratings of underlying obligations is one attribute that makes the Company’s insurance products attractive in the market.

An insurer’s financial strength rating itself is not specific to any particular policy or contract; a rating agency instead assigns such rating to the insured obligation. A financial strength rating does not refer to an insurer's ability to meet non-insurance obligations and is not a recommendation to purchase any policy or contract issued by an insurer or to buy, hold, or sell any security insured by an insurer. The insurance financial strength ratings assigned by the rating agencies are based upon factors that the rating agencies believe are relevant to policyholders and are not directed toward the protection of investors in AGL’s common shares. Ratings reflect only the views of the respective rating agencies assigning them and are subject to continuous review and revision or withdrawal at any time.

Low financial strength ratings or uncertainty over the Company’s ability to maintain its financial strength ratings for its insurance subsidiaries would have a negative impact on issuers’ and investors’ perceptions of the value of the Company’s insurance product. Therefore, the Company manages its business with the goal of achieving high financial strength ratings.

A major component in arriving at a financial guaranty insurer’s rating has been the rating agency’s assessment of the insurer’s capital adequacy, with each rating agency employing its own proprietary model. These capital adequacy approaches include “stress case” loss assumptions for various risks or risk categories. The rating agencies have at various times materially increased stress case loss assumptions for various risks or risk categories, in some cases later reducing such stress case losses. This approach has made predicting the amount of capital required to maintain or attain a certain rating more difficult. In addition, both S&P Global Ratings, a division of Standard & Poor’s Financial Services LLC (S&P), and Moody’s Investors Service, Inc. (Moody’s) have applied other factors, some of which are subjective, such as the insurer's business strategy and franchise value or the anticipated future demand for its product, to justify ratings for the Company’s insurance subsidiaries below the ratings implied by their own capital adequacy models. Currently, for example, S&P has concluded that Assured Guaranty’ insurance subsidiaries have “AAA” capital adequacy under the S&P model (but apply a downward adjustment due to a “largest obligor test” and rate them “AA”) and Moody’s has concluded that AG has “Aa” capital adequacy under the Moody’s model (but rates it A1 based on other factors including the rating agency’s assessment of competitive profile, future profitability and market share). The application of these additional factors makes it uncertain whether a rating downgrade could generally be avoided by raising additional capital or otherwise improving capital adequacy under the rating agency’s model.

Despite the unpredictable application of subjective factors that are in addition to a rating agency’s assessment of insurers’ capital adequacy, the Company has been able to maintain strong financial strength ratings. The Company believes that if the financial strength ratings of any of its insurance subsidiaries were downgraded from their current levels, such downgrade could result in downward pressure on the premium that such insurance subsidiary would be able to charge for its insurance. The Company believes that so long as its insurance subsidiaries continue to have financial strength ratings in the double-A category from at least one of S&P or Moody’s, they are likely to be able to continue writing financial guaranty business with a credit quality similar to that historically written. However, if neither S&P nor Moody’s were to maintain financial strength ratings of an insurance subsidiary in the double-A category, or if either S&P or Moody’s were to downgrade an insurance subsidiary below the single-A level, it could be extremely difficult or impossible for such insurance subsidiary to originate the current volume of new financial guaranty business with comparable credit characteristics.

The Company periodically assesses the value of each rating assigned to each of its companies and may, as a result of such assessment, request that a rating agency add or drop a rating from certain of its companies. For example, a Moody’s rating was dropped from Assured Guaranty Re Ltd. (AG Re) and Assured Guaranty Re Overseas Ltd. (AGRO) in 2015.

See Item 1A. Risk Factors — Strategic Risks, captioned “A downgrade of the financial strength or financial enhancement ratings of any of the Company’s insurance or reinsurance subsidiaries may adversely affect its business prospects.”

Market Demand and Competition

Financial Guaranty Insurance

Assured Guaranty is the market leader in the financial guaranty industry. The Company’s position in the market benefits from its ability to maintain strong financial strength ratings, its strong claims-paying resources, its proven willingness and ability to make claim payments to policyholders after obligors have defaulted, and its ability to achieve recoveries in respect of the claims that it has paid and to resolve its troubled public finance and structured finance exposures, including RMBS.

Market demand for financial guaranty insurance in the public finance (including infrastructure) market is generally driven by the difference in yield (or the credit spread) between an insured bond and an uninsured bond. When the difference in yield (or the credit spread) between a bond insured by Assured Guaranty and an uninsured bond is narrow, as is often the case in a low interest rate environment, investors may prefer greater yield over insurance protection, and issuers may find the cost savings from insurance less compelling. In contrast, when credit spreads are wider, there is comparatively more room for issuer savings and insurance premium. However, credit spreads may be narrower in a higher interest rate environment, as occurred in late 2022, and credit spreads may widen in a low interest rate environment, as occurred after the onset of the COVID-19 pandemic as a result of market concerns about the impact of the COVID-19 pandemic on some municipal credits. In the secondary public finance (including infrastructure) market, demand for financial guaranty insurance may also be influenced by capital requirements and counterparty credit exposures. For a discussion of the economic environment, see Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Overview — Economic Environment.

In the U.S. public finance market, Assured Guaranty is the only financial guaranty company active before the 2008 financial crisis that has maintained sufficient financial strength to write new business continuously since the crisis began. Assured Guaranty has only one direct competitor for public finance financial guaranty business, Build America Mutual Assurance Company (BAM), a mutual insurance company that commenced business in 2012.

The Company estimates that, of the new U.S. public finance bonds sold with insurance in 2025, the Company insured approximately 58% of the par, while BAM insured approximately 42%. The Company believes that BAM is effective in competing with it for small to medium sized U.S. public finance transactions in certain sectors, and may in the future compete for non-U.S. transactions. BAM sometimes prices its guaranties at levels that the Company does not believe produces an adequate rate of return and, therefore, the Company will not match. In addition, the Company believes that these pricing strategies may have a negative impact on the amount of premium it is able to charge for its insurance in other transactions. However, the Company believes it has competitive advantages over BAM due to: AG’s larger capital base; AG’s ability to insure larger transactions and issuances in more diverse bond sectors; BAM’s higher leverage ratios than those of AG; and AG’s strong financial strength ratings from multiple rating agencies (in the case of AG, AA+ from Kroll Bond Rating Agency (KBRA), AA from S&P and A1 from Moody’s, compared with BAM’s AA solely from S&P). Additionally, as a public company with access to both the equity and debt capital markets, Assured Guaranty may have greater flexibility to raise capital, if needed.

In the U.S. and non-U.S. structured finance markets, Assured Guaranty is the only financial guaranty insurance company currently writing new guaranties. Management considers the Company’s greater diversification to be a competitive advantage in the long run because it means the Company is not wholly dependent on conditions in any one market. The majority of the Company’s new structured finance business is represented by bilateral transactions with counterparties (typically insurance companies or banks) where the motivation to buy its product relates to capital savings, and/or single risk or sectoral risk management. In the securitization markets, uninsured execution occurs in both public and private transactions primarily where bonds are sold with sufficient credit or structural enhancement embedded in transactions, such as through overcollateralization, first loss insurance, excess spread or other terms, to make the bonds attractive to investors without bond insurance.

In the future, additional new entrants into the financial guaranty industry could reduce the Company’s new business prospects, including by furthering price competition or offering financial guaranty insurance on transactions with structural and security features that are more favorable to the issuers than those required by Assured Guaranty. However, the Company believes that the presence of additional guarantors might also increase the overall visibility and acceptance of the product by a broadening group of investors, and the fact that investors are willing to commit fresh capital to the industry may promote market confidence in the product.

In addition to financial guaranty insurance companies, Assured Guaranty competes with other forms of credit enhancement such as letters of credit or credit derivatives provided by banks and other financial institutions (some of which are governmental enterprises), other forms of capital savings or risk syndication, including nonpayment insurance, and direct guaranties of municipal, structured finance or other debt by federal or state governments or government sponsored or affiliated agencies. Alternative credit enhancement structures, and in particular federal government credit enhancement or other programs, can interfere with the Company’s new business prospects, particularly if they provide direct government-level guaranties, restrict the use of third-party financial guaranties or reduce the amount of transactions that might qualify for financial guaranties.

The Company believes that issuers and investors in securities will continue to purchase financial guaranty insurance, especially if credit spreads widen. U.S. municipalities have budgetary requirements that are best met through financings in the

fixed income capital markets. Historically, smaller municipal issuers have frequently used financial guaranties in order to access the capital markets with new debt offerings at a lower all-in interest rate than on an unguaranteed basis. In addition, the Company expects long-term debt financings for infrastructure projects will grow throughout the world, as will the financing needs associated with privatization initiatives or refinancing of infrastructure projects in developed countries.

The Company evaluates the amount of capital it requires based on an internal capital model as well as rating agency models and insurance regulations. The Company believes it has excess capital based on its internal capital model and rating agency models, and, to the extent permitted by insurance regulation or other regulatory authority, has been returning some of its excess capital to shareholders by repurchasing its common shares and paying dividends, and has been deploying some of its excess capital to acquire financial guaranty portfolios and diversify the Company’s sources of earnings.

Annuity Reinsurance

The life and annuity reinsurance market is highly competitive. The Company expects to face competition from established life and annuity reinsurance companies that have significant operating histories, strong financial strength ratings and long-standing client relationships. While the Company believes that its annuity reinsurance platform provides a compelling market proposition, it may experience difficulties executing its business strategies, including market acceptance of the Assured Life Re platform and obtaining acceptable market rates of return for business opportunities. See Item 1A. Risk Factors, Strategic Risks, captioned “Competition in the Company’s industries may adversely affect its financial condition, results of operations, capital, business prospects and share price.”

Financial Guaranty Insurance Acquisitions

Since 2009, the Company has acquired financial guaranty portfolios, including by acquiring legacy financial guarantors or acquiring (through reinsurance) substantial portions of their insured portfolios, and by commuting business that the Company had previously ceded prior to 2009 to various non-affiliated legacy financial guarantors and multiline reinsurers that were active in the financial guaranty reinsurance market. The Company also has periodically assumed, on a quota share basis, selected insured transactions from certain other legacy financial guarantors. The Company continues to investigate additional opportunities related to remaining legacy financial guaranty portfolios, but the number and size of the opportunities have decreased and there can be no assurance of whether or when the Company will find suitable opportunities on appropriate terms.

Insurance Subsidiaries

The Company conducts financial guaranty business through its financial guaranty insurance subsidiaries:

•Assured Guaranty Inc. (AG), domiciled in Maryland, and its insurance subsidiaries:

▪Assured Guaranty UK Limited (AGUK), domiciled in the U.K.;

▪Assured Guaranty (Europe) SA (AGE), domiciled in France;

•AG Re, domiciled in Bermuda, and its insurance subsidiary:

▪AGRO, domiciled in Bermuda.

The following is a description of the Company’s financial guaranty insurance subsidiaries:

•Assured Guaranty Inc. AG is located in New York and domiciled in Maryland, was incorporated in 1985 and commenced operations in 1988. It provides financial guaranty insurance and reinsurance in the U.S., U.K., European Economic Area (EEA) and certain other countries. Effective August 1, 2024, AG’s U.S. affiliate, Assured Guaranty Municipal Corp. (AGM) merged with and into AG, with AG as the surviving company. Prior to the merger, AGM was an insurance subsidiary of the Company.

•Assured Guaranty UK Limited AGUK provides financial guaranties in the U.K. and certain other non-EEA countries. AGUK is a U.K. incorporated private limited company licensed as a U.K. insurance company and located in England. AGUK was organized in 1990 and issued its first financial guaranty in 1994.

•Assured Guaranty (Europe) SA. AGE (together with AGUK, the European Insurance Subsidiaries) is a French incorporated company located in France and established in 2019 that has been authorized by the French insurance and banking supervisory authority, the Autorité de Contrôle Prudentiel et de Résolution (ACPR), to conduct financial guaranty business. AGE writes new business in the EEA.

•Assured Guaranty Re Ltd. AG Re primarily underwrites financial guaranty reinsurance of certain affiliated companies and third-party primary insurers. AG Re is incorporated under the laws of Bermuda and is registered and licensed as a Class 3B insurer under the Insurance Act 1978 and related regulations of Bermuda.

•Assured Guaranty Re Overseas Ltd. AGRO underwrites direct and assumed financial guaranty insurance, and also underwrites specialty business. AGRO is incorporated under the laws of Bermuda and is registered and licensed as a Bermuda Class 3A and Class C insurer.

The Company conducts its life and annuity reinsurance business through Assured Life Re, which was acquired by the Company on January 21, 2026. Assured Life Re is incorporated under the laws of Bermuda and is registered and licensed as a Bermuda Class E insurer.

Support of the European Insurance Subsidiaries

AG Support of AGUK

AG and AGUK have in place a co-guarantee structure pursuant to which each of AG and AGUK directly guarantees a share of certain issued obligations (Co-Guarantee Structure). Under the current Co-Guarantee Structure in effect since January 1, 2026: (i) AGUK directly guarantees 50% of the obligations issued in a particular transaction, subject to a guaranteed original principal amount limit of £100 million per transaction; (ii) AG directly guarantees 50% of the issued obligations, plus any principal amounts in excess of the foregoing AGUK limit; and (iii) AG also provides a second-to-pay guarantee for AGUK’s guaranteed portion of the obligations. For the 12-month period ending December 31, 2025, the Co-Guarantee Structure split was 15% AGUK and 85% AG. The Co-Guarantee Structure has been in place since 2011 for public finance business and since 2021 for non-public finance business.

Separate and apart from the Co-Guarantee Structure, AG provides support to AGUK through a quota share and excess of loss reinsurance agreement (Reinsurance Agreement) and a net worth maintenance agreement (Net Worth Agreement).

Under the quota share cover of the Reinsurance Agreement, AG reinsures varying proportional shares of most of the outstanding financial guaranties that AGUK wrote prior to the initial implementation of the Co-Guarantee Structure in 2011. The quota share cover of the Reinsurance Agreement also obligates AG to reinsure 85% of new business written by AGUK where the Co-Guarantee Structure cannot be utilized; currently, there is no such outstanding business at AGUK. Under the excess of loss cover of the Reinsurance Agreement, AG is obligated to pay AGUK quarterly the amount (if any) necessary to ensure that AGUK’s incurred and paid losses and loss adjustment expenses (LAE) as of the quarter end do not cause AGUK’s capital resources to fall below 110% of the greatest amount of capital that AGUK may be required to maintain as a condition to carrying on a financial guarantee business in the U.K. AG secures its quota share reinsurance obligations to AGUK under the Reinsurance Agreement by pledging collateral generally equal to 102% of the sum of AG’s assumed liabilities from AGUK.

Under the Net Worth Agreement, AG is obligated to make capital contributions to AGUK in amounts sufficient to ensure that AGUK maintains capital resources equal to 110% of the greatest amount of capital that AGUK may be required to maintain as a condition to carrying on a financial guarantee business in the U.K., subject to limitations on the amounts of individual and aggregate contributions AG can make under the agreement without approval (or non-disapproval) of the Maryland Insurance Administration (MIA). The Net Worth Agreement obligates AG to provide AGUK with support similar to that which AG also provides AGUK under the excess of loss cover of the Reinsurance Agreement, except the latter is meant to protect against erosion of AGUK’s capital resources due to insurance and/or reinsurance losses in AGUK’s insured portfolio, while the former is meant to protect against an erosion of AGUK’s capital resources for other reasons (e.g., poor investment performance or origination expenses exceeding premium). AG has never been required to make any contributions to AGUK’s capital under the current Net Worth Agreement; however, AG may elect to make, from time to time and subject to MIA approval or non-disapproval, capital contributions to AGUK not required by the Net Worth Agreement.

AG Support of AGE

AGE has in place similar reinsurance and capital support agreements as are in place with AGUK.

AG’s reinsurance agreements with AGE generally apply to all AGE policies that insure business in EEA jurisdictions. These agreements consist of: (i) a quota share reinsurance agreement pursuant to which AG provides AGE with 90% proportional reinsurance for new business written by AGE since its authorization in January 2020; (ii) a second quota share reinsurance agreement pursuant to which AG reinsures approximately 70-100% of certain pre-2020 business transferred

to AGE by AGUK; and (iii) an excess of loss reinsurance agreement, similar to the excess of loss cover of AG’s Reinsurance Agreement with AGUK, pursuant to which AG is obligated to pay AGE quarterly the amount (if any) necessary to ensure that AGE’s incurred and paid losses and LAE as of the quarter end do not cause AGE’s capital resources to fall below 110% of the greatest amount of capital that AGE may be required to maintain as a condition to carrying on a financial guarantee business in France. AG secures its quota share reinsurance obligations to AGE under the agreements described above by pledging collateral generally equal to 102% of AG’s assumed liabilities from AGE.

AG also has in place with AGE a net worth maintenance agreement that is similar to AG’s Net Worth Agreement with AGUK - i.e., the former obligates AG to ensure that AGE maintains capital resources at least equal to 110% of its greatest capital requirement for carrying on a financial guarantee business in France, subject to limitations on the amount of individual and aggregate contributions that AG can make under the agreement without MIA approval or non-disapproval. AG may elect to make, from time to time and subject to MIA approval or non-disapproval, capital contributions to AGE not required by the net worth maintenance agreement.

Other Group Support of the European Insurance Subsidiaries for Certain Legacy Business

AG Re also provides reinsurance support to the European Insurance Subsidiaries for certain legacy business that was insured prior to 2009 by AGUK. Some of this business continues to reside at AGUK, while some was transferred to AGE by AGUK. AG Re does not currently provide direct reinsurance support for new business being written by AGUK or AGE. AG Re secures its reinsurance of the legacy business by pledging collateral generally equal to 102% of its assumed liabilities from each of AGUK and AGE.

Asset Management

Until July 1, 2023, the Company served as an investment adviser to primarily collateralized loan obligations (CLOs) and opportunity funds, through Assured Investment Management LLC (AssuredIM LLC) and its investment management affiliates (together with AssuredIM LLC, AssuredIM). Beginning July 1, 2023, the Company participates in the asset management business through its ownership interest in Sound Point, LP and certain of its investment management affiliates (together with Sound Point, LP, Sound Point), as described below.

On July 1, 2023, Assured Guaranty contributed to Sound Point, LP most of its asset management business, other than that conducted by Assured Healthcare Partners LLC (AHP) (AssuredIM Contributed Business), as contemplated by the transaction agreement entered into with Sound Point on April 5, 2023 (Transaction Agreement). Assured Guaranty received, subject to certain potential post-closing adjustments, approximately 30% of the common interests in Sound Point, LP, and certain other interests in Sound Point. See Part II, Item 8. Financial Statements and Supplementary Data, Note 1. Business and Basis of Presentation, for additional information.

In addition, in accordance with the terms of a letter agreement (Letter Agreement), effective July 1, 2023, AG (i) engaged Sound Point as its sole alternative credit manager and (ii) transitioned to Sound Point the management of certain existing alternative investments and related commitments. The Letter Agreement also provides that AG, including through its investment subsidiary AG Asset Strategies LLC, would, subject to the terms and conditions of the Letter Agreement, make new investments in funds, other vehicles and separately managed accounts managed by Sound Point which, when aggregated with the alternative investments and commitments transitioned from the Company and any reinvestments (collectively, Sound Point Investments), and investments made by other Assured Guaranty affiliates, will total $1 billion. AG has made substantial investments with Sound Point across a variety of their strategies in order to seek to enhance its investment returns and anticipates continuing to invest with Sound Point pursuant to the terms of the Letter Agreement. The Letter Agreement contemplates a long-term investment partnership between Sound Point and Assured Guaranty, whereby AG has agreed to reinvest all returns of capital from Sound Point Investments for a period of 15 years, until July 1, 2038. Similarly, the Letter Agreement provides that AG reinvest all gains and dividends from Sound Point Investments for the first two years of Sound Point’s engagement, and reinvest half of all such gains and dividends thereafter until July 1, 2033 (the transactions contemplated under the Transaction Agreement and the Letter Agreement, the Sound Point Transaction). On July 1, 2028, AG may choose to reduce the amounts invested or required to be reinvested in certain Sound Point Investments under the Letter Agreement, subject to adjustment of Assured Guaranty’s portion of its ownership interest in Sound Point. To the extent not required to be reinvested by the Letter Agreement, all proceeds from Sound Point Investments received in accordance with their operative investment documents can be distributed to AG. See Part II, Item 8. Financial Statements and Supplementary Data, Note 7. Investments and Cash.

The Company’s ownership interest in Sound Point advances one of the Company’s key business strategies to diversify its sources of earnings into fee-based industries that leverage its core competency in credit. In addition, the Company’s

alternative investments made under the Letter Agreement with Sound Point furthers the Company’s goal of diversifying and expanding the categories and types of its investments.

In July 2023, Assured Guaranty sold all of its equity interests in AHP, which manages healthcare funds, to an entity owned and controlled by the managing partner of AHP (AHP Transaction), thereby disposing of its remaining asset management business. In connection with the AHP Transaction, the Company agreed to remain a strategic investor in certain AHP managed funds, retained its portion of carried interest in certain AHP managed funds and received other consideration.

See Item 1A. Risk Factors, Strategic Risks, captioned “Competition in the Company’s industries may adversely affect its financial condition, results of operations, capital, business prospects and share price,” “Strategic transactions may not result in the benefits anticipated,” “The Company’s investments in Sound Point are subject to the risks of Sound Point’s business that may adversely affect the Company’s financial condition, results of operations, capital, business prospects and share price,” and “The Company’s interest in Sound Point is subject to the risks normally associated with a noncontrolling interest.”

Asset Management Strategies

The Company participates in the asset management business through its ownership interest in Sound Point. Sound Point, LP was founded in 2008 and has five main credit strategies: (i) CLOs and performing credit, (ii) private credit, (iii) structured credit, (iv) opportunistic credit, and (v) commercial real estate credit. Sound Point also makes co-investments across the foregoing strategies. The Company invests in certain of Sound Point, LP’s credit strategies. These strategies are implemented for clients, including the Company, through funds and customized separately managed accounts and co-investment opportunities as further described below and in Sound Point, LP’s Firm Brochure on Form ADV Part 2A filed with the SEC. Sound Point, LP’s Firm Brochure and other U.S. Securities and Exchange Commission (SEC) filings are maintained by Sound Point, LP, which remains solely responsible for their content.

Sound Point, LP’s CLO Strategy focuses on launching and managing CLOs (SP CLOs) whose investment assets primarily include corporate senior-secured bank loans and bonds. Sound Point, LP’s CLO Strategy also includes managing funds and vehicles that invest in securities issued by SP CLOs and residual interests in warehouse facilities for such CLOs. Sound Point, LP’s Performing Credit Floating Rate Strategy primarily focuses on performing non-investment grade corporate senior-secured bank loans and bonds.

Sound Point, LP’s Private Credit Strategy is comprised of the following sub-strategies: Middle Market Direct Lending Capital Solutions and Specialty Finance. Middle Market Direct Lending primarily focuses on privately negotiated, secured loans to U.S. middle-market companies. Capital Solutions primarily focuses on investments in senior secured debt, junior secured debt, accounts receivable financings, mezzanine debt and equity or equity linked securities and Specialty Finance Strategy which invests in specialty finance assets, financial technology, marketplace lending, consumer finance, structured finance and securitized products related to specialty finance lenders.

Sound Point, LP’s Structured Credit Strategy primarily invests in the equity and debt of Third Party CLOs as well as the residual interests in warehouse facilities for such CLOs.

Sound Point, LP’s Opportunistic Credit Strategy is comprised of both a Credit Opportunity Strategy and a Loan Opportunity Strategy. The Credit Opportunity Strategy primarily focuses on corporate bonds, senior-secured bank loans and equities and the Loan Opportunity Strategy primarily focuses on distressed bonds, distressed bank loans, public and private equity, and trade claims.

Sound Point, LP’s Commercial Real Estate Credit Strategy focuses on commercial mortgage loans and debt where commercial real estate properties serve as the underlying collateral.

Market Demand and Competition

Asset Management

The Company’s Asset Management segment primarily consists of its ownership interest in Sound Point, a diversified alternative asset manager with expertise in credit and more than $44 billion in assets under management (AUM) as of September 30, 2025. Sound Point’s stated primary investment objectives across its products are (i) to preserve capital in all market conditions and (ii) to generate attractive rates of return with low volatility. Sound Point manages assets on behalf of institutions, pensions, foundations, insurance companies, wealth management firms, family offices and high net worth individuals.

Sound Point operates in highly competitive markets with many other firms in every aspect of the asset management industry, including raising funds, seeking investments, and hiring and retaining professionals. Sound Point’s ability to increase and retain AUM is directly related to the performance of the assets it manages as measured against market averages and the performance of its competitors. Some of Sound Point’s competitors may be much larger, enjoy a lower cost of funds and access to funding and other resources that are not available to Sound Point. In addition, some of Sound Point’s competitors may have higher risk tolerances or different risk assessments that depart from Sound Point’s stated investment objectives, which could allow them to consider a wider variety of investments that Sound Point may not be willing to match.

Investments

The Company invests primarily in investment-grade fixed-maturity securities and short-term investments, as well as various alternative investments. Income from the Company’s investments is one of the primary sources of cash flow supporting its ability to make claim payments and bear other operational costs, as well as its capital management objectives. The Company’s principal objectives in managing its investment portfolio are to maintain sufficient liquidity to cover unexpected stress in the insurance portfolio; to maximize after tax book income; to manage investment risk within the context of the underlying portfolio of insurance risk; and to preserve the highest possible ratings for each Assured Guaranty subsidiary.

If the Company’s calculations with respect to its insurance subsidiaries’ liabilities are incorrect or other unanticipated payment obligations arise, or if the Company improperly structures its investments to meet these and other corporate liabilities, it could have unexpected losses, including losses resulting from forced liquidation of investments. The investment policies of the Company’s insurance subsidiaries are subject to insurance law requirements, and may change depending upon regulatory, economic, rating agency and market conditions and the existing or anticipated financial condition and operating requirements, including the tax position, of Assured Guaranty. The performance of invested assets is subject to the ability of the Company and its investment managers to select and manage appropriate investments.

As of December 31, 2025, the investment portfolio had a carrying value of $8.5 billion and consisted primarily of the following:

Fixed-maturity securities and short-term investments: As of December 31, 2025, $7.4 billion or 87% of the investment portfolio consisted of fixed-maturity securities and short-term investments. As of December 31, 2025, the majority (67%, or $5.7 billion) of the fixed-maturity securities and short-term investments was managed by Goldman Sachs Asset Management, L.P., Wellington Management Company, LLP, and MacKay Shields LLC. Each of these investment managers has discretionary authority over the portion of the investment portfolio it manages, within the limits of the investment guidelines approved by the Company’s Board of Directors (the Board or AGL’s Board). Each manager is compensated based upon a fixed percentage of the market value of the portion of the portfolio being managed by such manager. During 2025, Wellington Management Company LLP owned or managed funds that own more than 5% of AGL’s common shares. The available-for-sale fixed-maturity securities in the investment portfolio primarily consist of investment-grade obligations of state and political subdivisions, U.S. government and agencies, corporate securities, mortgage-backed and other asset-backed securities.

In addition, as of December 31, 2025, $228 million of the available-for-sale fixed-maturity securities were CLO equity tranches, $168 million were bonds issued by a U.K. regulated utility to which the Company has insured exposure, and $140 million (based on fair value) were securities insured by the Company with expected losses that it subsequently purchased in order to mitigate the economic effect of such insured expected losses (Loss Mitigation Securities). The Company considers CLO equity tranches to be a component of its alternative investment strategy.

The Company also had $114 million (based on fair value) of Contingent Value Instruments (CVIs), obtained as part of the resolution of the Company’s exposure to insured Puerto Rico credits experiencing payment default other than the Puerto Rico Electric Power Authority (PREPA), all of which were classified as trading securities. See Part II, Item 8. Financial Statements and Supplementary Data, Note 7. Investments and Cash.

Other invested assets and consolidated investment vehicles (CIVs): As of December 31, 2025, the carrying value of the Company’s ownership interest in Sound Point was $415 million and is reported in “other invested assets” on the consolidated balance sheets.

The Company also has alternative investments in a variety of investment strategies and asset classes offered by Sound Point as described above in “ — Asset Management Strategies,” as well as alternative investments managed by AHP and other parties. As of December 31, 2025, the Company’s other invested assets primarily consisted of funds focused on private healthcare investing, asset-based/specialty finance, CLOs and commercial real estate finance. As of December 31, 2025, one

Sound Point managed fund was consolidated and classified as a CIV. The Company’s interest in that CIV based on net-asset-value was $57 million.

See Part II, Item 8. Financial Statements and Supplementary Data, Note 8. Variable Interest Entities, for information on the CIVs.

Risk Management

Organizational Structure

The Board oversees the risk management process. The Board employs an enterprise-wide approach to risk management that supports the Company’s business plans within an acceptable level of risk. Risk assessment and risk management encompass not only understanding the risks the Company faces and what steps management is taking to manage those risks, but also understanding what level of risk is appropriate for the Company. The Board annually approves the Company’s business plan, taking risk management into account. It also approves the Company’s risk appetite statement, which articulates the Company’s tolerance for risk and describes the general types of risk that the Company accepts or attempts to avoid. The involvement of the Board in setting the Company’s business strategy is a key part of its assessment of management’s risk tolerance and a determinant of what constitutes an appropriate level of risk for the Company.

While the Board has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibility for risk assessment and risk management. The Risk Oversight Committee of the Board oversees the standards, controls, limits, underwriting guidelines and policies that the Company establishes and implements in respect of credit underwriting and risk management. It focuses on management of credit risks as well as other risks, including, but not limited to, market, financial, legal, operational risks (including information technology, cybersecurity and data privacy risks), and risks relating to the Company's reputation and ethical standards. In addition, the Audit Committee of the Board is responsible for, among other matters, reviewing policies and processes related to risk assessment and risk management, including the Company’s major financial risk exposures and the steps management has taken to monitor and control such exposures, in coordination with the Risk Oversight Committee. It also oversees information technology, cybersecurity and data privacy as related to financial systems and controls, and reviews compliance with related legal and regulatory requirements. The Compensation Committee of the Board reviews risks to the Company arising from its compensation program. The Finance Committee of the Board oversees the Company’s investment portfolio (including alternative investments) and the Company’s capital structure, liquidity, financing arrangements, rating agency matters, and any corporate development activities in support of the Company’s financial plan. The Nominating and Governance Committee of the Board oversees risk at the Company by developing appropriate corporate governance guidelines, identifying qualified individuals to become Board members and, in coordination with the Compensation Committee, making plans for senior management succession. The Environmental and Social Responsibility Committee oversees the Company’s risk and opportunities related to environmental issues, such as climate-related financial risk, as well as aspects of human capital management, including its strategies, policies and initiatives.

The board of directors of each of the Company’s insurance subsidiaries has overall responsibility for the system of governance, oversight of the business and affairs and establishment of the key strategic direction and key financial objectives, including risk management, of its respective company.

The Company has established several management committees to develop enterprise level risk management guidelines, and policies and procedures for the Company’s insurance subsidiaries that are tailored to their respective businesses, providing multiple levels of review, analysis and control.

The Company’s management committees responsible for risk management include:

•Portfolio Risk Management Committee—The portfolio risk management committee is responsible for enterprise risk management for the Company’s insurance business and focuses on measuring and managing credit, market and liquidity risk for the Company’s insurance business. This committee establishes company-wide credit policy for the Company’s direct and assumed insured business. It implements specific underwriting procedures and limits for the Company and allocates underwriting capacity among the Company’s subsidiaries. All transactions in new asset classes or new jurisdictions, or otherwise outside the Company’s Board-approved risk appetite statement or its risk limits, must be approved by this committee.

•Risk Management—Each financial guaranty insurance subsidiary has a committee responsible for conducting an in-depth review of the insured portfolios of the relevant subsidiary, focusing on varying portions of the portfolio at each meeting. These committees review and may revise internal ratings assigned to the insured transactions and

review sector reports, monthly product line surveillance reports and compliance reports, and are responsible for assisting in the management of risk and oversight of their respective company’s risk management framework and processes. This includes monitoring their respective company’s compliance with risk strategy, risk appetite, risk limits, as well as overseeing and challenging their respective company’s risk management and compliance functions. In carrying out its responsibilities, each of the risk management committees considers numerous factors that could impact their insured portfolios, including macroeconomic factors, long term trends and climate-related financial risk.

•Workout Committee—This committee receives reports from surveillance and workout personnel on transactions insured by the Company that might benefit from active loss mitigation or risk reduction and approves loss mitigation or risk reduction strategies for such transactions.

•Reserve Committees—Each financial guaranty insurance subsidiary has a committee responsible for oversight of reserves for insured obligations. The reserve committees review the reserve methodology and assumptions for each major asset class or significant below-investment-grade (BIG) transaction, as well as the loss projection scenarios used and the probability weights assigned to those scenarios. The reserve committees establish reserves for their respective insurance subsidiaries, taking into consideration supporting information provided by surveillance and portfolio analytics personnel, and are responsible for approving changes to assumptions that have a significant impact on expected losses.

•Assumptions Committees—The financial guaranty insurance subsidiaries have committees responsible for setting the assumptions, other than assumptions related to BIG exposures that use transaction-specific models within the scope of the reserve committees, used to calculate the Company’s probability of default and loss in various portfolio loss scenario and economic capital models. When setting these assumptions, each committee considers relevant historical internal and external experience and any potential changes to market conditions that could affect these parameters going forward.

In addition, management and the boards of the Company’s subsidiaries evaluate alternative investments prior to committing any funds to such investments. In the case of AG, the board has delegated the approval of alternative investments to an investment committee consisting of directors who are the insurer’s Chief Investment Officer, Chief Executive Officer, Chief Operating Officer and Chief Financial Officer; the activities of the investment committee are further reviewed by the insurer’s full board of directors. See “Asset Management and Alternative Investments” below.

Enterprise Risk Management

The business units and functional areas are responsible for identifying, assessing, monitoring, reporting and managing their own risks. The Chief Risk Officer and other risk management personnel are separate from the business units and are responsible for developing the risk management framework, ensuring applicable risk management policies and procedures are followed consistently across business units, and for providing objective oversight and aggregated risk analysis.

The internal audit function (Internal Audit) provides independent assurance around effective risk management design and control execution. On a quarterly basis, or more frequently when required, Internal Audit reports its findings directly to the Audit Committee of the AGL Board and informs the Chief Executive Officer and other senior management of any material issues identified during their audits.

The Company has established an enterprise level risk appetite statement, approved by the Board, and risk limits, that govern the Company’s risk-taking activities, with similar documents governing the activities of each operating subsidiary. Risk management personnel monitor a variety of key risk indicators on an ongoing basis and work with the business units to take the appropriate steps to manage the Company’s established risk appetites and tolerances. Risk management also uses an internally developed economic capital model to project potential ultimate losses in the insured portfolio as well as on alternative investments, and analyze the related capital implications for the Company. Risk management also performs stress and scenario testing to both validate model results and assess the potential financial impact of emerging risks and major strategic initiatives such as acquisitions or releases of capital.

Quarterly risk reporting keeps the Board, its Risk Oversight Committee and senior management informed about material risk-related developments. At least once each year, risk management personnel prepare an Own Risk and Solvency Assessment for the Company as a whole and each of the operating companies (Commercial Insurer Solvency Self-Assessment for AG Re and AGRO) which reports the results of capital modeling, the status of key risk indicators and any emerging risks to the Risk Oversight Committee. In addition, the Company performs in-depth reviews annually of risk topics of interest to

management and the Board. To the extent potentially significant business activities or operational initiatives are considered, the Chief Risk Officer analyzes the possible impact on the Company’s risk profile and capital adequacy.

Surveillance of Insured Transactions

The Company’s surveillance personnel are responsible for monitoring and reporting on the performance of each risk in its insured portfolio and tracking aggregation of risk. The primary objective of the surveillance process is to monitor trends and changes in transaction credit quality, detect any deterioration in credit quality, change or affirm ratings during reviews, and recommend remedial actions to management. The Company assigns internal credit ratings at closing to all transactions in the insured portfolio, and surveillance personnel recommend rating affirmations or adjustments to those ratings via the risk management committees to reflect changes in transaction credit quality. The Company monitors its insured portfolio and refreshes its internal credit ratings on individual exposures in quarterly, semi-annual or annual review cycles based on the Company’s view of the exposure’s quality, loss potential, volatility and sector. Ratings on exposures in sectors identified as under the most stress or with the most potential volatility are reviewed every quarter, although the Company may also review a rating in response to developments impacting the credit when a ratings review is not scheduled.

The review cycle and scope vary based upon transaction type and credit quality. In general, the review process includes the collection and analysis of information from various sources, including trustee and servicer reports, performance reports from Intex (a commercially available structured finance reporting system), financial statements, general industry or sector news and analyses, and rating agency reports. Additionally, the Company uses various quantitative tools, scorecards and models to assess transaction performance and identify situations where there may have been a change in credit quality. Surveillance activities may include discussions with or site visits to issuers, servicers, collateral managers or other parties to a transaction. Surveillance may adopt augmented procedures in response to various events, as it has done in response to the COVID-19 pandemic, major natural disasters, and the transition away from the London Interbank Offered Rate as a reference rate.

For transactions that the Company has assumed, the ceding insurers are generally responsible for conducting ongoing surveillance of the exposures that have been ceded to the Company. The Company’s surveillance personnel monitor the ceding insurer’s surveillance activities on exposures ceded to the Company through a variety of means, including reviews of surveillance reports provided by the ceding insurers, meetings and discussions with their analysts and, in certain cases, independently review assumed transactions.

Workouts

The Company has personnel drawn from its surveillance, risk management, legal and other functions who are responsible for managing workout, loss mitigation and risk reduction situations. They work to develop and implement strategies on transactions that are experiencing loss or could possibly experience loss. They, along with the workout committee, develop strategies designed to enhance the ability of the Company to enforce its contractual rights and remedies and mitigate potential losses. They also engage in negotiation discussions with transaction participants and, when necessary, manage (along with legal personnel) the Company’s litigation proceedings. They may also recommend and facilitate open market or negotiated purchases of securities that the Company has insured, negotiate or otherwise implement consensual terminations of insurance coverage prior to contractual maturity, or engage in other loss mitigation strategies. In addition, the Company’s surveillance personnel work with servicers of RMBS transactions to enhance their performance.

Asset Management and Alternative Investments

The Company’s investment management personnel and other risk personnel (together, the Investment Team) monitor the Company's ownership interest in Sound Point, and investments in Sound Point funds and other alternative investments. Investment Team personnel are responsible for the evaluation and due diligence processes for proposed new investments, and submit recommended investment actions to management, the boards of directors of the insurance subsidiaries, or AG’s investment committee in accordance with the Company's investment guidelines and procedures. Investment team members monitor existing investments and provide periodic reporting at least quarterly to senior management, AGL’s Board and the Board's Risk Oversight and Finance Committees.

Data Protection

The Company is subject to local, state, and national laws and regulations in the U.S., U.K., the European Union (EU), the other EEA countries that comply with data protection laws in the EU, and other non-U.S. jurisdictions that require financial institutions and other businesses to protect personal and other sensitive information and provide notice of their privacy and

security practices relating to the collection, disclosure and other processing of personal information. The Company is also subject to local, state, and national laws and regulations in various jurisdictions in which it does business that require notification to affected individuals and regulators regarding data security breaches. To address these requirements, the Company has established and implemented policies and procedures that are intended to protect the privacy and security of personal information that comes into the Company’s possession or control, and to comply with applicable laws and regulations. Company policies and procedures include, but are not limited to, specific technical, administrative, and physical safeguards for personal information, periodic risk assessments on privacy and security measures, monitoring and testing, an incident response plan that requires Company personnel to promptly report suspected and actual data breach incidents to designated management representatives, an enterprise-wide data governance program, and regularly maintained records that demonstrate the Company’s accountability for compliance with the core privacy principles relating to the processing of personal information and applicable data protection laws. The Company has imposed similar requirements, as applicable, on third parties with whom it shares personal information including through a rigorous vendor selection and management process. The Company engages its personnel and strives to enhance data privacy and security awareness through Company training, which is mandatory for all employees globally on an annual basis. See Item 1C. Cybersecurity.

Changing Climate Risks

The Company has long considered environmental impacts as part of its underwriting process, in particular with regard to U.S. public finance transactions. Global awareness of changing climate conditions and weather patterns has drawn greater attention to the financial implications and long-term consequences of frequent or severe natural disaster perils (e.g., storms and wildfires). As a financial guarantor of municipal and structured finance transactions, the Company does not have direct insurance exposure to natural perils but does face the risk that its obligors’ ability to pay debt service may be impacted as a result of such perils and the exacerbating effect extreme weather or deteriorating climatic conditions may have on their operations and/or financial condition.

The Company continues to enhance its approach to the consideration of climate risk in the origination, underwriting, credit approval, and surveillance of its insured exposures and has integrated climate risk into its risk management and control functions. Credit underwriting submissions are required to include an assessment of environmental and/or transitional risk factors as part of the underwriting analysis. Specifically, the vulnerability of obligors is evaluated with respect to climatic changes (e.g., sea level rise, droughts), extreme weather events (e.g., hurricanes, tornadoes, floods) or geological events (e.g., earthquakes, volcanic activity) as well as resilience factors (e.g., mitigation capabilities, adaptation capacity) to determine if such environmental issues could materially impact an obligor’s expected performance.

The Company’s assessment of how climate risks may impact a prospective obligor’s ability to pay debt service is informed by its extensive experience in municipal finance coupled with proprietary analytics and third-party data and insights. To improve the Company’s understanding of changing climate conditions and to develop the analytical tools needed to measure and manage the related financial risks, the Company has been investing in both talent and technology. The Company’s risk management function, which includes climate science expertise, continues to develop and expand analytical capabilities to evaluate climate risk and assess any potential negative impacts on the proposed obligor’s ability to pay debt service.

The Company is also exposed indirectly to climate trends and extreme weather events that might impair the performance of securities in its investment portfolio, which consists predominantly of fixed-maturity securities. Nevertheless, environmental issues, including regulatory changes, changes in supply or demand characteristics of fuels, and extreme weather events, may impact the value of certain securities. The investment guidelines incorporate material environmental factors into the investment analysis to enhance the quality of investment decisions. On an annual basis, the Company requests and reviews reports from its primary investment managers on any material non-financial risks (including vulnerability to climate risks or exposure to extreme weather events) that may adversely impact returns.

The Company believes that the physical effects of evolving climate risks on the Company’s business operations are not likely to be material and the Company does not anticipate capital expenditures for climate related projects.

Regulatory Reporting. As the global community continues to address and mitigate the effects of changing climatic conditions, regulators across jurisdictions have imposed requirements or issued guidance regarding climate risk management and related reporting. Several of the Company’s subsidiaries are subject to regulatory reporting with respect to managing and disclosing the impact of changing climate conditions and the related financial risks. The Company continues to monitor regulatory developments and meet requirements applicable to its subsidiaries. To date, the costs associated with complying with regulatory reporting obligations have not had a material impact on the Company’s business, financial condition, and results of operations.

Governance. The Environmental and Social Responsibility Committee and the Risk Oversight Committee of AGL’s Board provide oversight of the Company's approach to addressing climate-related risk in accordance with their respective charters. The Environmental and Social Responsibility Committee reviews updates on the consideration of environmental risks in the Company’s insurance risk management and its investment portfolio, as well as legislative and regulatory developments of significance to the Company’s environmental initiatives and related oversight. The Risk Oversight Committee reviews the establishment and implementation of enterprise risk management policies and practices.

The Company also has an environmental risk working group composed of senior members of the Company’s credit, underwriting, surveillance, and risk management departments to review the impact of environmental risk on the Company, including the development of objective risk measures, metrics and methodologies needed to evaluate the financial impact of evolving climate conditions and extreme weather events on obligors in its insured portfolio on both aggregate and individual risk levels.

Regulation

Overview

The Company is a public company subject to SEC rules and regulations. It is also subject to insurance-related statutes, regulations and supervision by the U.S. states and territories and the non-U.S. jurisdictions in which it does business; the degree and type of regulation varies from one jurisdiction to another. In addition, from July 1, 2023, following the Sound Point Transaction, the Company participates in the asset management business through its ownership interest in Sound Point, which is an investment adviser registered with the SEC that is subject to asset management-related statutes and regulations. The Company expects that the statutes and regulations applicable to the Company and to Sound Point will continue to evolve for the foreseeable future.

United States Regulation

Insurance and Financial Services Regulation

AGL has one insurance subsidiary domiciled in the U.S.; AG is a Maryland domiciled insurance company licensed to write financial guaranty insurance and reinsurance in 50 U.S. states, the District of Columbia, Guam, Puerto Rico and the U.S. Virgin Islands.

Insurance Holding Company Regulation

AG is subject to the insurance holding company laws of Maryland, its domiciliary jurisdiction, as well as other jurisdictions where it is licensed to do insurance business. These laws generally require AG to register with the MIA and annually to furnish financial and other information about the operations of companies within its holding company system. Generally, all transactions between AG, on the one hand, and any companies in the holding company system, on the other, including sales, loans, reinsurance and service agreements, must be fair, reasonable and equitable, and, if material or of a specified category, such as reinsurance or service agreements, require prior notice to and approval or non-disapproval by the MIA.

Change of Control

Before a person can acquire control of a U.S.-domiciled insurance company, prior written approval must be obtained from the insurance commissioner of the state where the insurer is domiciled or deemed commercially domiciled. Generally, state statutes provide that control over a domestic insurer is presumed to exist if any person, directly or indirectly, owns, controls, holds with the power to vote, or holds proxies representing, 10% or more of the voting securities of such insurer. Because a person acquiring 10% or more of AGL’s common shares would indirectly control the same percentage of the stock of AG, the insurance change of control laws of Maryland would likely apply to such acquisition. Accordingly, a person acquiring 10% or more of AGL’s common shares must either file a disclaimer of control of AG with the insurance commissioner of the State of Maryland (the Maryland Commissioner) or apply to acquire control of AG with the Maryland Commissioner. However, this presumption does not create a safe harbor for acquisitions below the 10% threshold, which may still result in a control determination. Significantly, an acquirer of less than 10% of an insurer’s voting securities may still be deemed to control the insurer based on all the facts and circumstances, including the terms and conditions of the proposed transaction. Moreover, a control relationship can arise from a contract or other factors, in the absence of any ownership of voting securities of an insurer.

Prior to approving an application to acquire control of a domestic insurer, the Maryland Commissioner will consider factors such as the financial strength of the applicant, the integrity and management of the applicant’s board of directors and executive officers, the applicant's plans for the management of the board of directors and executive officers of the insurer, the applicant’s plans for the future operations of the insurer and any anti-competitive results that may arise from the consummation of the acquisition of control. These review requirements may discourage potential acquisition proposals and may delay, deter or prevent a change of control involving AGL that some or all of AGL’s shareholders might consider to be desirable, including, in particular, unsolicited transactions.

Other State Insurance Regulations

State insurance authorities have broad regulatory powers with respect to various aspects of the business of U.S. insurance companies, including licensing these companies to transact business, “accrediting” reinsurers, determining whether assets are “admitted” and counted in statutory surplus, prohibiting unfair trade and claims practices, establishing reserve requirements and solvency standards, regulating investments and dividends and, in certain instances, approving policy forms and related materials and approving premium rates. State insurance laws and regulations require AG to file financial statements with insurance departments in every U.S. state or jurisdiction where it is licensed, authorized or accredited to conduct insurance business, and its operations are subject to examination by those departments at any time. AG prepares statutory financial statements in accordance with Statutory Accounting Principles, or SAP, and procedures prescribed or permitted by these departments. State insurance departments conduct periodic examinations of the books and records, financial reporting, policy filings and market conduct of insurance companies domiciled in their states, generally once every three to five years.

The MIA, the regulatory authority of the domiciliary jurisdiction of AG, conducts a periodic financial examination of insurance companies domiciled in Maryland, usually at five-year intervals. In 2023, the MIA last completed an examination of AG. The examination was for the five-year period ending December 31, 2021 and was a joint examination of both AG and its former affiliate, AGM, by the MIA and AGM’s domiciliary regulator, the New York State Department of Financial Services (NYDFS). The examination reports from the MIA and the NYDFS did not note any significant regulatory issues.

State Dividend Limitations

Maryland. One of the primary sources of cash for the payment of debt service by Assured Guaranty Municipal Holdings Inc. (AGMH) and Assured Guaranty US Holdings Inc. (AGUS) and for repurchases of shares and dividends by AGL is the receipt of dividends from AG. Under Maryland’s insurance law, AG may pay any dividend or other distribution in an amount that, together with any other dividends or distributions paid in the prior 12 months, does not exceed the lesser of (i) 10% of its policyholders’ surplus (as of the prior December 31); or (ii) 100% of its adjusted net investment income; provided, that, AG notifies the Maryland Commissioner of the proposed payment within five business days following declaration and at least ten days before payment. The Maryland Commissioner may declare that such dividend or distribution not be paid if it finds that AG’s policyholders’ surplus would be inadequate after payment or if payment could lead AG to a hazardous financial condition. “Adjusted net investment income” means the sum of (x) AG’s net investment income during the 12-month period ending December 31 of the preceding year (excluding realized capital gains and pro rata distributions of its own securities), and (y) AG’s net investment income (excluding realized capital gains) from the three calendar years prior to the preceding calendar year that has not already been paid out as dividends. A dividend or distribution to a shareholder of AG in excess of the foregoing limitation would constitute an “extraordinary dividend” or “extraordinary distribution,” which must be paid out of AG’s “earned surplus” and reported to, and approved by, the MIA prior to payment. "Earned surplus" is that portion of AG’s surplus that represents the net earnings, gains or profits (after deduction of all losses) that have not been distributed to its shareholders as dividends or transferred to stated capital or capital surplus, or applied to other purposes permitted by law, but does not include unrealized capital gains and appreciation of assets. See Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources — Insurance Subsidiaries, for the maximum amount of dividends or other distributions that can be paid without regulatory approval, recent dividend and distribution history and other recent capital movements.

Contingency Reserves

AG is required by Maryland insurance law and regulations to establish a contingency reserve, as reported on its statutory financial statements, to protect policyholders. Maryland insurance laws and regulations determine the calculation of the contingency reserve and the period of time over which it must be established and, subsequently, can be released.

Releases from an insurer’s contingency reserve may be permitted under specified circumstances in the event that actual loss experience exceeds certain thresholds or if the reserve accumulated is deemed excessive in relation to the insurer's outstanding insured obligations.

From time to time, AG has obtained the approval of the Maryland Commissioner to release contingency reserves based on losses or because the accumulated reserve is deemed excessive in relation to the insurer’s outstanding insured obligations.

Maryland insurance laws and regulations require regular, quarterly contributions to contingency reserves, but such laws and regulations permit the discontinuation of such quarterly contributions to an insurer's contingency reserves when the insurer’s aggregate contingency reserves for a particular line of business (i.e., municipal or non-municipal) exceed the sum of the insurer’s outstanding principal for each specified category of obligations within the particular line of business multiplied by the specified contingency reserve factor for each such category. In accordance with such laws and regulations, and with the approval of the MIA, AG ceased making quarterly contributions to its contingency reserves for both municipal and non-municipal business beginning in the fourth quarter of 2014, but resumed its quarterly contributions to its contingency reserves for municipal business in the third quarter of 2024 due to the merger on August 1, 2024 of AGM with and into AG, with AG surviving. The ongoing cessation of quarterly contributions to AG’s contingency reserves for non-municipal business is expected to continue for as long as AG satisfies the foregoing condition for such line of business.

Single and Aggregate Risk Limits

The Code of Maryland Regulations establishes single risk limits for financial guaranty insurers applicable to all obligations insured by a financial guaranty insurer that are issued by a single entity and backed by a single revenue source. For example, under the limit applicable to municipal obligations, the insured average annual debt service for a single risk, net of qualifying reinsurance and collateral, may not exceed 10% of the sum of the insurer's policyholders’ surplus and contingency reserves. In addition, the insured unpaid principal of municipal obligations attributable to any single risk, net of qualifying reinsurance and collateral, is limited to 75% of the insurer’s policyholders’ surplus and contingency reserves.

Under the limit applicable to qualifying asset-backed securities, the lesser of:

•the insured average annual debt service for a single risk, net of qualifying reinsurance and collateral, or

•the insured unpaid principal (reduced by the extent to which the unpaid principal of the supporting assets exceeds the insured unpaid principal) divided by nine, net of qualifying reinsurance and collateral,

may not exceed 10% of the sum of the insurer’s policyholders’ surplus and contingency reserves, subject to certain conditions.

Single-risk limits are also specified for other categories of insured obligations, and generally are more restrictive than those described above for municipal and asset-backed obligations. Obligations not qualifying for an enhanced single-risk limit are generally subject to a catch-all or “other” limit under which the unpaid principal of the single risk, net of qualifying reinsurance and collateral, may not exceed 10% of the sum of the insurer's policyholders’ surplus and contingency reserves. For example, “triple-X” and “future flow” securitizations, as well as unsecured corporate obligations and unsecured investor-owned utility obligations, are generally subject to this catch-all or “other” single-risk limit.

The Code of Maryland Regulations also establishes an aggregate risk limit on the basis of the aggregate net liability insured by a financial guaranty insurer as compared with its statutory capital. “Aggregate net liability” is defined for this purpose (and the additional limits discussed below) as the outstanding principal and interest of guaranteed obligations insured, net of qualifying reinsurance and collateral. Under this limit, an insurer’s combined policyholders’ surplus and contingency reserves must not be less than the sum of various percentages of aggregate net liability for various categories of specified obligations. The percentage varies from 0.3333% for certain municipal obligations to 4.0% for certain non-investment-grade obligations.

Other Limits Applicable to Financial Guaranty Insurers

The Code of Maryland Regulations, as well as the laws of other states where AG is licensed that specifically regulate financial guaranty insurance, limits a financial guaranty insurer’s aggregate net liability to municipal (and related) obligations that lack (i) an underlying investment grade rating or an investment grade designation from at least one NRSRO acceptable to the state’s insurance commissioner or superintendent (Investment Grade) or (ii) an underlying investment grade determination from the Securities Valuation Office of the National Association of Insurance Commissioners (BIG/Non-Rated Exposure). Under the Code of Maryland Regulations, the BIG/Non-Rated Exposure limitation for an AA-rated insurer such as AG is 15% of the insurer’s aggregate net liability to all municipal (and related) obligations. In other states the BIG/Non-Rated Exposure limitation is 5% of the insurer’s aggregate net liability to all municipal (and related) obligations regardless of the insurer’s rating.

The Code of Maryland Regulations and the laws of other states regulating financial guaranty insurance also generally prohibit financial guaranty insurers from insuring obligations not denominated in U.S. dollars unless the insured currency is (a) that of an Organization for Economic Co-operation and Development country or other country whose sovereign rating is Investment Grade or (b) not disapproved by the state’s insurance commissioner or superintendent. In addition, the Code of Maryland Regulations and other applicable laws limit the insurer’s aggregate net liability to such permitted non-U.S. dollar obligations to 25% of the insurer’s aggregate net liability to all obligations (the FX Percentage).

The Maryland Commissioner and the state insurance commissioners or superintendents of the other states specifically regulating financial guaranty insurance generally have broad discretion to order a financial guaranty insurer to cease new business originations if the insurer fails to comply with single or aggregate risk limits or exceeds the BIG/Non-Rated Exposure limitation or FX Percentage, but, based on the Company’s experience, are likely to show a willingness to work with AG for isolated or temporary instances of non-compliance.

Investments

AG is subject to laws and regulations that require diversification of its investment portfolio and limit the amount of investments in certain asset categories, such as BIG fixed-maturity securities, foreign investments, real estate, equity investments, and derivatives. Failure to comply with these laws and regulations would cause investments exceeding regulatory limitations to be treated as non-admitted assets for purposes of measuring surplus, and, in some instances, would require divestiture of such non-qualifying investments. In addition, any investment by AG must be authorized or approved by its board of directors or a committee thereof that is responsible for supervising or making such investment.

Group Regulation

In connection with AGL’s establishment of tax residence in the U.K., as discussed in greater detail under “Tax Matters” below, the MIA has been designated as group-wide supervisor for the Assured Guaranty group. Group-wide supervision by the MIA results in additional regulatory oversight over Assured Guaranty, particularly with respect to group-wide enterprise risk, and may subject Assured Guaranty to new regulatory requirements and constraints.

In January 2026, the Insurance Amendment (No. 2) Act 2025 became operative, which provided for certain amendments to Bermuda’s Insurance Act 1978 impacting Bermuda’s insurance group supervision framework (Insurance Act Amendment). The Insurance Act Amendment, among other things, imposes a mandatory requirement for the Bermuda Monetary Authority (BMA) to assume the role of group supervisor for Bermuda insurance groups meeting certain criteria, including groups with an ultimate parent entity incorporated or registered in Bermuda, such as Assured Guaranty. The Insurance Act Amendment contemplates a transition period of one year. Accordingly, Assured Guaranty expects that, after receipt of formal notice from the BMA confirming its role of group supervisor and completion of the transition period, the BMA will assume the role of its group supervisor, at which time Assured Guaranty will become subject to applicable group capital, reporting and governance requirements under Bermuda law.

U.S. Credit for Reinsurance Requirements for Non-U.S. Reinsurance Subsidiaries

The Company’s Bermuda reinsurance subsidiaries, AG Re and AGRO, may be affected by regulatory requirements in the 50 U.S. states, District of Columbia, American Samoa, Guam, Northern Marianas, Puerto Rico, and U.S. Virgin Islands (collectively, NAIC Jurisdictions) governing the ability of a ceding company to receive credit on its statutory financial statements for reinsurance provided by a reinsurer. In general, under such requirements, a ceding company that obtains reinsurance from a reinsurer that is licensed, accredited or approved by the ceding company’s state jurisdiction of domicile is permitted to reflect in its statutory financial statements a credit in an aggregate amount equal to the ceding company's liability for unearned premiums (which are that portion of premiums written which applies to the unexpired portion of the policy period), and loss and LAE reserves ceded to the reinsurer. NAIC Jurisdictions, however, generally also permit a credit on the statutory financial statements of a ceding insurer for reinsurance obtained from a non-licensed or non-accredited reinsurer to the extent that the reinsurer secures its reinsurance obligations to the ceding insurer by providing collateral in the form of a letter of credit, trust fund or other acceptable security arrangement. Certain of those jurisdictions also permit such non-licensed/non-accredited reinsurers that meet certain specified requirements to apply for “certified reinsurer” status. If granted, such status allows the certified reinsurer to post less than 100% collateral (the exact percentage depends on the certifying jurisdiction’s view of the reinsurer's financial strength) and the applicable ceding company will still qualify, on the basis of such reduced collateral, for full credit for reinsurance on its statutory financial statements with respect to reinsurance contracts renewed or entered into with the certified reinsurer on or after the date the reinsurer becomes certified. Each NAIC Jurisdiction has adopted laws and regulations allowing for the elimination of reinsurance collateral requirements for unauthorized reinsurers in qualifying non-U.S. jurisdictions that (i) meet specified requirements, such as minimum capital and surplus amounts and

minimum solvency or capital ratios, and (ii) provide certain commitments to the ceding insurer’s domiciliary regulator, such as submission to jurisdiction and the filing of annual audited financial statements.

AG Re and AGRO are not licensed, accredited or approved in any state and have established trusts to secure their reinsurance obligations. In 2017, AGRO obtained certified reinsurer status in Missouri, which allows AGRO to post 10% collateral in respect of any reinsurance assumed from a Missouri-domiciled ceding company on or after the date of AGRO’s certification (although, currently, AGRO does not assume any such reinsurance). See “Non-U.S. Regulation —Bermuda—Bermuda Insurance Regulation” for Bermuda regulations applicable to AG Re and AGRO.

Regulation of Swap Transactions Under Dodd-Frank

AG is subject to direct and indirect regulation under U.S. federal law. In particular, its derivatives activities are directly and indirectly subject to a variety of regulatory requirements under the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank Act). Based on the size of AG’s derivatives portfolios, AGL does not believe AG is required to register with the Commodity Futures Trading Commission as a “major swap participant” or with the SEC as a “major securities-based swap participant.” Certain of the Company's subsidiaries may be subject to Dodd-Frank Act requirements to post margin for, or to clear on a regulated execution facility, future swap transactions or with respect to certain amendments to legacy swap transactions, if they enter into such transactions.

Regulation of U.S. Asset Management Business

Since July 1, 2023, following the Sound Point Transaction, the Company participates in the asset management business through its ownership interest in Sound Point. The Company is an approximately 30% owner of Sound Point, does not control the business, management or policies of Sound Point and relies upon Sound Point to make appropriate decisions and operate in a manner consistent with applicable rules and regulations. Sound Point is registered as an investment adviser with the SEC and is subject to the requirements and regulations of the U.S. Investment Advisers Act of 1940, as amended (the Advisers Act). As a registered investment adviser, Sound Point, LP and certain other Sound Point entities must submit periodic filings with the SEC on Forms ADV, which are publicly available. The Advisers Act also imposes additional requirements on registered advisers, including the maintenance of a Code of Ethics addressing potential conflicts of interest, an effective compliance program, recordkeeping and reporting, disclosure, limitations on cross and principal transactions between an adviser and its advisory clients and general anti-fraud prohibitions. Furthermore, private funds advised by Sound Point rely on exemptions from various requirements of the Securities Act, the Exchange Act, the U.S. Investment Company Act of 1940, as amended (the Investment Company Act), the Commodity Exchange Act and the U.S. Employee Retirement Income Security Act of 1974, as amended (ERISA). In addition, registered investment companies advised by Sound Point are subject to the requirements of the Securities Act, the Exchange Act and the Investment Company Act and rely on exemptions from the Commodity Exchange Act and ERISA.

Non-U.S. Regulation

General

A portion of the Company’s business is conducted in non-U.S. countries. Generally, the Company’s subsidiaries operating in non-U.S. jurisdictions must satisfy local regulatory requirements. Certain of these jurisdictions require registration and periodic reporting by insurance and reinsurance companies that are licensed or authorized in such jurisdictions and are controlled by other entities. Applicable legislation also typically requires periodic disclosure concerning the entity that controls the insurer and reinsurer and the other companies in the holding company system and prior approval of intercompany transactions and transfers of assets, including, in some instances, payment of dividends by the insurance and reinsurance subsidiary within the holding company system.

In addition to these licensing, disclosure and asset transfer requirements, the Company’s non-U.S. operations are also regulated in various jurisdictions with respect to, among other matters, policy language and terms, amount and type of reserves, amount and type of capital to be held, amount and type of local investment, local tax requirements, and restrictions on changes in control. AGL, as a Bermuda-domiciled holding company, is also subject to shareholding restrictions. Such shareholding restrictions of AGL and restrictions on changes in control of our non-U.S. operations may discourage potential acquisition proposals and may delay, deter or prevent a change of control of AGL, including through transactions, and, in particular, unsolicited transactions, that some or all of its shareholders might consider to be desirable. See Item 1A. Risk Factors — Risks Related to Applicable Law, Litigation and GAAP, captioned “Applicable insurance laws may make it difficult to effect a change of control of AGL.”

Bermuda

The Bermuda Monetary Authority (the Authority) regulates the Company’s operating insurance and reinsurance subsidiaries in Bermuda. AG Re, AGRO, and Assured Life Re are each an insurance company currently registered and licensed under the Insurance Act 1978 of Bermuda, amendments thereto and related regulations (collectively, the Insurance Act). AG Re is registered and licensed as a Class 3B insurer and is authorized to carry on general insurance business (as understood under the Insurance Act), subject to any conditions attached to its license and to compliance with the requirements imposed by the Insurance Act.

AGRO is registered and licensed as both a Class 3A insurer and a Class C long-term (life) insurer, and therefore carries on both general and long-term (life) business (as understood under the Insurance Act), subject to any conditions attached to its license. In particular, AGRO must keep its accounts in respect of its general business and its long-term (life) business separate in respect of any other business. AGRO is required to maintain both a general business fund and a long-term (life) business fund (as defined in the Insurance Act).

Assured Life Re is registered and licensed as a Bermuda Class E long-term (life) insurer, which is the license class for long-term (life) insurers with total assets of more than $500 million.

Bermuda Insurance Regulation

The Insurance Act, as enforced by the Authority, imposes on AG Re, AGRO, and Assured Life Re a variety of requirements and restrictions, including the filing of annual U.S. GAAP financial statements and audited statutory financial statements; compliance with minimum enhanced capital requirements; compliance with the Authority’s Insurance Code of Conduct; compliance with the Authority’s Insurance Sector Operational Cyber Risk Management Code of Conduct; compliance with minimum solvency and liquidity standards; restrictions on the declaration and payment of dividends and distributions; preparation and publication of an annual Financial Condition Report providing details on measures governing the business operations, corporate governance framework, solvency and financial performance of the insurer and reinsurer; restrictions on changes in control of regulated insurers and reinsurers; restrictions on the reduction of statutory capital; and the need to have a principal representative and a principal office (as understood under the Insurance Act) in Bermuda. The Insurance Act grants to the Authority the power to cancel insurance licenses, supervise, investigate and intervene in the affairs of insurance and reinsurance companies and in certain circumstances share information with foreign regulators.

Shareholder Controllers

Pursuant to provisions in the Insurance Act, any person who becomes a holder of 10% or more, 20% or more, 33% or more or 50% or more of the Company’s common shares must notify the Authority in writing within 45 days of becoming such a holder. The Authority has the power to object to such a person if it appears to the Authority that the person is not fit and proper to be such a holder. In such a case, the Authority may require the holder to reduce their shareholding in the Company and may direct, among other things, that the voting rights attached to their common shares are not exercisable.

Minimum Solvency Margin and Enhanced Capital Requirements

Under the Insurance Act, AG Re, AGRO, and Assured Life Re must each ensure that the value of its general business statutory assets exceeds the amount of its general business statutory liabilities by an amount greater than a prescribed minimum solvency margin and each company’s applicable enhanced capital requirement, which is established by reference to either its Bermuda Solvency Capital Requirement (BSCR) model or an approved internal capital model. The BSCR model is a risk-based capital model which provides a method for determining an insurer’s capital requirements (statutory economic capital and surplus) by establishing capital requirements for ten categories of risk in the insurer’s business: fixed income investment risk, equity investment risk, interest rate/liquidity risk, currency risk, concentration risk, premium risk, reserve risk, credit risk, catastrophe risk and operational risk.

Restrictions on Dividends and Distributions

The Insurance Act limits the declaration and payment of dividends by AG Re, AGRO, and Assured Life Re, including by prohibiting each company from declaring or paying any dividends during any financial year if it is in breach of its prescribed minimum solvency margin, minimum liquidity ratio or enhanced capital requirement, or if the declaration or payment of such dividends would cause such a breach. Dividends cannot exceed an insurer’s current outstanding statutory surplus. In accordance with the Insurance Act, AG Re, AGRO, and Assured Life Re may declare or pay in any financial year dividends of up to 25% of its total statutory capital and surplus (as shown on its previous financial year’s statutory balance sheet) without seeking prior

approval from the Authority. AG Re, AGRO, and Assured Life Re are prohibited from making dividend declarations or payments in excess of this 25% threshold in any financial year without certification to the Authority that the company will continue to meet its relevant margins. The Insurance Act also prohibits AGRO and Assured Life Re, as Class C and Class E licensed long-term (life) insurers, respectively, from declaring or paying any dividends to any person other than a policyholder unless its approved actuary certifies that the proposed amount of the dividend would not exceed the excess of funds available to satisfy its long-term (life) business obligations. Further, AG Re, AGRO, and Assured Life Re are permitted to make capital distributions of up to 15% of its prior year statutory capital (as shown in its previous financial year statutory balance sheet). AG Re, AGRO, and Assured Life Re must obtain the Authority’s prior approval before making capital distributions in excess of the 15% threshold. See “Minimum Solvency Margin and Enhanced Capital Requirements” above and “Minimum Liquidity Ratio” below.

The Companies Act 1981 of Bermuda (Companies Act) also limits the declaration and payment of dividends and other distributions by Bermuda companies such as AGL and its Bermuda subsidiaries, which, in addition to AG Re, AGRO, and Assured Life Re, also include Cedar Personnel Ltd. (collectively, the Bermuda Subsidiaries). Such companies may only declare and pay a dividend or make a distribution out of contributed surplus (as understood under the Companies Act) if there are reasonable grounds for believing that the company is, and after the payment will be, able to meet and pay its liabilities as they become due and the realizable value of the company’s assets will not be less than its liabilities.

Minimum Liquidity Ratio

The Insurance Act provides a minimum liquidity ratio for general business. An insurer engaged in general business is required to maintain the value of its relevant assets at not less than 75% of the amount of its relevant liabilities. Relevant assets include cash and time deposits, quoted investments, unquoted bonds and debentures, first liens on real estate, investment income due and accrued, accounts and premiums receivable, reinsurance balances receivable, funds held by ceding insurers and any other assets which the Authority accepts on application. The relevant liabilities are total general business insurance reserves and total other liabilities less deferred income tax and sundry liabilities (by interpretation, those not specifically defined) and letters of credit, corporate guaranties and other instruments.

Personal Information Protection Act 2016

The Personal Information Protection Act 2016 (PIPA) is the principal Bermuda legislation regulating the right to personal informational privacy. In December 2016, PIPA sections relating generally to the establishment, staffing, funding, and general powers of the Privacy Commissioner came into force and in January 2020 a Privacy Commissioner was appointed. On January 1, 2025, PIPA was fully implemented. PIPA applies to every organization (which includes any individual, entity or public authority) that uses personal information in Bermuda where that personal information is used by automated or other means which form, or are intended to form, part of a structured filing system. For the purposes of PIPA, “personal information” means any information about an identified or identifiable individual (meaning a natural person), and “use” or “using” are very broadly defined and effectively include possessing or carrying out any operation on personal information. AGL and its Bermuda subsidiaries are subject to PIPA requirements. As such, to the extent that AGL or the Bermuda Subsidiaries use individuals’ personal information in Bermuda, such entity will need to comply with the applicable sections of PIPA.

Beneficial Ownership

The Beneficial Ownership Act 2025 (BO Act) came into force on November 3, 2025 requiring certain legal persons in Bermuda to identify beneficial owners and maintain a beneficial ownership register. For so long as AGL’s shares are listed on an “appointed stock exchange” (which includes the New York Stock Exchange), AGL and its Bermuda Subsidiaries are exempted from the requirements of the BO Act, save for the requirement to confirm such exempted status with the Registrar of Companies in Bermuda and file with the Registrar of Companies in Bermuda proof of that exemption including the name and jurisdiction of the relevant stock exchange.

Certain Other Bermuda Law Considerations

Although AGL is incorporated in Bermuda, it is classified as a non-resident of Bermuda for exchange control purposes by the Authority. Pursuant to its non-resident status, AGL may engage in transactions in currencies other than Bermuda dollars and there are no restrictions on its ability to transfer funds (other than funds denominated in Bermuda dollars) in and out of Bermuda or to pay dividends to U.S. residents who are holders of its common shares.

AGL is not currently subject to taxes computed on profits or income or computed on any capital asset, gain or appreciation. Bermuda companies pay, as applicable, annual government fees, business fees, payroll tax and other taxes and duties. See “— Tax Matters—Taxation of AGL and Subsidiaries—Bermuda.”

United Kingdom Insurance and Financial Services Regulation

Each of AGUK and Assured Guaranty Finance Overseas Ltd. (AGFOL) are subject to the FSMA, which covers financial services relating to deposits, insurance, investments and certain other financial products. Under FSMA, effecting or carrying out contracts of insurance by way of business in the U.K. each constitutes a “regulated activity” requiring authorization by the appropriate regulator.

The PRA and the Financial Conduct Authority (FCA) are the main regulatory authorities responsible for insurance regulation in the U.K. These two regulatory bodies cover the following areas:

•the PRA, a part of the Bank of England, is responsible for prudential regulation of certain classes of financial services firms, including insurance companies, and

•the FCA is responsible for the prudential regulation of all non-PRA firms and the regulation of market conduct by all firms.

AGUK, as an insurance company, is regulated by both the PRA and the FCA. They impose on AGUK a variety of requirements and restrictions, including minimum solvency capital requirements; change of control; reporting requirements; supervision of management; intervention and enforcement; and fees and levies. AGFOL, as an insurance intermediary, is regulated by the FCA. AGFOL’s permissions from the FCA allow it to introduce business to AG, so that AGFOL can arrange financial guaranties underwritten by AG. AGFOL is not authorized as an insurer and does not itself take risk in the transactions it arranges or places.

PRA Supervision and Enforcement

The PRA has extensive powers to intervene in the affairs of an authorized firm, including the power in certain circumstances to withdraw the firm’s authorization to carry on a regulated activity. The PRA carries out the prudential supervision of insurance companies like AGUK through a variety of methods, including the collection of information from statistical returns, the review of accountants’ reports and insurers’ annual reports and disclosures, visits to insurance companies and regular formal interviews. The PRA takes a risk-based approach to the supervision of insurance companies.

The PRA assesses, on an ongoing basis, whether insurers are acting in a manner consistent with safety and soundness and appropriate policyholder protection, and whether they meet, and are likely to continue to meet, threshold conditions. The PRA weights its supervision towards those issues and those insurers that, in its judgment, pose the greatest risk to its regulatory objectives. It is forward-looking, assessing its objectives not just against current risks, but also against those that could plausibly arise in the future. Its risk assessment framework looks at the insurer’s risk context, the potential impact of failure of the insurer and mitigating factors.

Other U.K. Regulatory Requirements

In 2010, it was agreed between AGUK’s management and its then regulator, the Financial Services Authority (now the PRA), that new business written by AGUK would be guaranteed using a co-guarantee structure pursuant to which AGUK would co-guarantee municipal and infrastructure transactions with AGM and structured finance transactions with AG. As a result of the merger on August 1, 2024 of AGM with and into AG, with AG surviving, the co-guarantor for both types of transactions is now AG. AGUK’s financial guaranty for each transaction covers a proportionate share of the total exposure, and AG guarantees the remaining exposure under the transaction. Under the current co-guarantee structure effective January 1, 2026 (i) AGUK directly guarantees 50% of the obligations issued in a particular transaction, subject to a guaranteed original principal amount limit of £100 million per transaction; (ii) AG directly guarantees 50% of the issued obligations, plus any principal amounts in excess of the foregoing AGUK limit; and (iii) AG also provides a second-to-pay guarantee for AGUK’s guaranteed portion of the obligations. For the 12-month period ending December 31, 2025, the co-guarantee structure split was 15% AGUK and 85% AG. See “—Insurance—Support of the European Insurance Subsidiaries.”

Solvency UK and Solvency Requirements

Solvency II took effect from January 1, 2016 in the U.K. and remained in effect as part of the U.K.’s retained EU law after the withdrawal of the U.K. from the EU. See “Solvency II and Solvency Requirements,” below. On December 31, 2024, as part of Brexit reform, the U.K. government revoked Solvency II in the U.K. and the prudential regime provisions for insurers were moved and assimilated into the PRA’s Rulebook and policy material (Solvency UK). Solvency UK provides rules on capital adequacy, governance and risk management and regulatory reporting and public disclosure. Under Solvency UK, AGUK is subject to certain limits and requirements, including the maintenance of a minimum solvency capital requirement (which depends on the type and amount of insurance business a company writes and the other risks to which it is exposed) and the establishment of technical provisions, which include projected losses and premium earnings. Failure to maintain capital at least equal to the capital requirements under Solvency UK is one of the grounds on which the wide powers of intervention conferred upon the PRA may be exercised. AGUK calculates its solvency capital requirements using the Standard Formula under Solvency UK which establishes capital requirements for underwriting risk, market risk, counterparty default risk and operational risk.

AGUK calculates its minimum required capital according to the solvency criteria applicable in the UK and is in compliance.

Restrictions on Dividend Payments

U.K. company law prohibits each of AGUK and AGFOL 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 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 PRA’s capital requirements may in practice act as a restriction on dividends for AGUK.

Change of Control

Under FSMA, when a person decides to acquire or increase “control” of a U.K. authorized firm (including an insurance company) they must give the PRA (if regulated by the PRA and FCA) or the FCA (if regulated solely by the FCA) notice in writing before making the acquisition. The PRA and the FCA have up to 60 working days (without including any period of interruption) in which to assess a change of control case. Any person (a company or individual) that directly or indirectly acquires 10% or 20% (depending on the type of firm, the “Control Percentage Threshold”) or more of the shares, or is entitled to exercise or control the exercise of the Control Percentage Threshold or more of the voting power, of a U.K. authorized firm or its parent undertaking is considered to “acquire control” of the authorized firm. Broadly speaking, the 10% threshold applies to banks, insurers and reinsurers (but not brokers) and Markets in Financial Instruments Directive (MiFID) investment firms, and the 20% threshold to insurance brokers and certain other firms that are Non-Directive firms for the purposes of Solvency UK.

U.K. Withdrawal from the European Union

Through 2019, AGUK wrote business in the U.K. and various countries throughout the EU as well as certain other non-EU countries. In mid-2019, to address the impact of the withdrawal of the U.K. from the EU, AGL established AGE as a French incorporated company. AGE was authorized by the French insurance and banking supervisory authority, the ACPR, to conduct financial guarantee business from January 2, 2020, and from that date AGUK ceased the underwriting of new business within the EEA. In October 2020, in preparation for Brexit, AGUK transferred to AGE certain existing AGUK policies relating to risks in the EEA under the Part VII Transfer.

AGUK will continue to write new business in the U.K. and certain other non-EEA countries.

France

As an insurance company licensed in France, AGE is regulated by the ACPR and is subject to the provisions of Solvency II as well as related EU delegated regulations as implemented in France, and by the French Insurance Code and the Monetary and Financial Code, both of which set out the primary rules governing the insurance industry in France. In accordance with French insurance regulation and Solvency II, AGE is permitted to carry on its activities in the countries of the EEA where it is authorized to operate under the freedom to provide services regime.

French regulation of insurance companies imposes on AGE a variety of requirements and restrictions, including minimum solvency capital requirements; change of control; reporting requirements; supervision of management; and intervention and enforcement.

ACPR Supervision and Enforcement

The ACPR has extensive powers to intervene in the affairs of an insurance company, including the power in certain circumstances to withdraw the company’s authorization to carry on a regulated activity. The ACPR carries out the prudential supervision of insurance companies like AGE through a variety of methods, including the collection of information from statistical returns, the review of accountants' reports and insurers’ annual reports and disclosures, visits to insurance companies and regular formal interviews.

The ACPR assesses, on an ongoing basis, whether insurers are acting in a manner consistent with safety and soundness and appropriate policyholder protection, and whether they meet, and are likely to continue to meet, threshold conditions. The ACPR is forward-looking, assessing its objectives not just against current risks, but also against those that could plausibly arise in the future. Its risk assessment framework looks at the insurer’s risk context, the potential impact of failure of the insurer and mitigating factors.

Solvency II and Solvency Requirements

Solvency II is the legal and regulatory basis for the supervision of insurance firms in France. It provides rules on capital adequacy, governance, risk management, and regulatory reporting and public disclosure. Under Solvency II, AGE is subject to certain limits and requirements, including the maintenance of a minimum solvency capital requirement (which depends on the type and amount of insurance business a company writes and the other risks to which it is exposed) and the establishment of technical provisions, which include projected losses and premium earnings. Failure to maintain capital at least equal to the capital requirements under Solvency II is one of the grounds on which the wide powers of intervention conferred upon the ACPR may be exercised.

Among other things, Solvency II introduced a revised risk-based prudential regime which includes the following features: (1) assets and liabilities are generally to be valued at their market value; (2) the amount of required economic capital is intended to ensure, with a probability of 99.5%, that regulated insurance firms are able to meet their obligations to policyholders and beneficiaries over the following 12 months; and (3) reinsurance recoveries are treated as a separate asset (rather than being netted off the underlying insurance liabilities). AGE calculates its solvency capital requirements using the Standard Formula under Solvency II and is in compliance.

Restrictions on Dividend Payments

French company law prohibits AGE from declaring a dividend to its shareholders unless it has “profits and/or reserves available for distribution.” The determination of whether a company has profits available for distribution is based on its accumulated realized profits less its accumulated realized losses. While French law imposes no statutory restrictions on an insurer's ability to declare a dividend, the ACPR’s capital requirements may, in practice, act as a restriction on dividends for AGE.

Change of Control

The French insurance code has requirements regarding acquisitions, disposals, and increases or decreases in ownership of a French-licensed insurance company.

Any transaction enabling a person (a company or individual), acting alone or in concert with other persons, to acquire, increase, dispose of or reduce its ownership in an insurance company licensed in France requires express or implied approval from the ACPR: (i) where such transaction results directly or indirectly in the proportion of shares or voting rights held by that person or those persons rising above 10%, 20%, one-third or 50% of all shares or voting rights; (ii) where the insurance or reinsurance company becomes a subsidiary of that person or those persons; and (iii) where the transaction allows this person or persons to exercise a significant influence over the management of this company.

As a matter of principle, the ACPR has 60 business days from the date on which it acknowledges receipt of the notification of the transaction to notify the reporting entity and the insurance company whose ownership change is contemplated of its refusal or approval of the transaction. In approving or refusing the transaction, the ACPR takes into account various factors, including the reputation of the acquirer, the effect of the transaction on the business and the management of the

company, the impact of the transaction on the financial strength of the company, or the ability of the company to continue to comply with applicable regulation.

Human Capital Management

The Company recognizes that its workforce, as a key driver of long-term performance, is among its most valued assets. Accordingly, the Company’s principal human capital management objectives are to attract, hire, retain, develop, and support the highest quality employees, including talented and experienced business leaders who drive its corporate strategies and build long-term shareholder value. To promote these objectives, the Company’s human capital management programs are designed to reward and support employees with competitive compensation and benefit packages in each of its locations around the globe, and with professional development opportunities to cultivate talented employees and prepare them for critical roles and future leadership positions.

As of December 31, 2025, the Company employed 367 people worldwide. Other than in the EEA, none of the Company’s employees are subject to collective bargaining agreements. The Company believes its employee relations are satisfactory.

Talent Development and Retention

Learning and Development. The Company invests in the professional development of its workforce because it believes that encouraging employees to realize their full capabilities enhances job satisfaction, leads to increased performance, and enables the Company to cultivate a pipeline of internal talent for succession planning. To support the advancement of its employees, the Company endeavors to strengthen their knowledge and skills by providing access to training, including in leadership, management and effective communication skills, mentoring opportunities, as well as tuition reimbursement assistance.

Mentoring. The Company believes its culture is collegial, collaborative and conducive to informal mentorship, knowledge sharing, and the development of role-related skills. In addition, all employees have access to a formal one-on-one mentoring program as well as mentoring circles which provide additional learning resources, facilitate the onboarding of new recruits and reinforce connectedness.

Compensation and Benefits. The Company designed its compensation program to attract, retain, and motivate talented individuals and to recognize and reward outstanding achievement. The components of the program consist of base salary and may include performance-based incentive compensation in the form of an annual cash incentive and deferred compensation in the form of cash and/or equity. The Company believes that a compensation program with both short-term and long-term awards provides fair and competitive compensation and aligns the interests of employees and investors. The Company offers a benefits package designed to promote and support the physical and mental health of its employees as well as financial security. Benefits include life and health (medical, dental and vision) insurance, retirement savings plans (including Company matches of employee contributions), an employee stock purchase plan, hybrid work schedules, paid time off, paid family leave, an employee assistance program, commuter benefits, tuition reimbursement, and child, elder and pet care assistance.

Assured Guaranty employs a number of practices to help ensure that its compensation program is competitive, and aligns with the Company's goals. To promote consistency and fairness, the Company's compensation function is centralized. In addition, the Company conducts periodic reviews of its compensation program and works with independent compensation and benefits consultants to help ensure that its compensation program reflects best practices and current market standards.

Culture

Ethical and Respectful Conduct. The Company seeks to foster and maintain strong ethical standards and a reputation as a business that conducts itself professionally and with a high degree of integrity. In addition, the Company works to provide and support a respectful and inclusive environment that values the abilities of each employee, which the Company believes leads to enhanced engagement, maximizing individual performance, and improving retention. Education and awareness are critical components in promoting the Company's cultural values across the organization. Upon onboarding and annually, the Company requires all employees to complete training in the Company's Global Code of Ethics as well as its policies on the prevention of sexual harassment and discrimination. The Company also provides additional targeted training and guidance to specific personnel regarding anti-fraud, anti-bribery and anti-corruption related matters.

Employee-led Initiatives. The Company supports several employee-led initiatives that enable employees to influence and enhance the employee experience. Employee-led initiatives also provide additional opportunities for employees to develop

and demonstrate their leadership and organizational skills, engage with colleagues across departments and offices, and champion programs and causes they value. Assured Guaranty has five employee resource groups (ERGs), selected based on employee feedback. Membership in the ERGs is voluntary and open to all employees, regardless of whether they identify with the group’s focus, and all of our ERGs include members who do not share those characteristics. The ERGs prepare strategic plans that incorporate the Company’s business objectives into their programming. The Company also has two employee-led committees: one committee that directs its philanthropic efforts by selecting charitable organizations with which to partner and by sourcing community volunteer activities, and a second committee that works to promote an inclusive culture in support of the Company’s commitment to anti-discrimination and equal opportunity in the workplace.

Employee Engagement; Feedback. The Company utilizes employee engagement surveys, conducted by a third-party provider to foster confidentiality, to gauge the effectiveness of its efforts to enhance the employee experience and to gain insight into employee perceptions about various aspects of the work environment.

Governance. The Board’s Environmental and Social Responsibility Committee and Compensation Committee, pursuant to their respective charters, provide oversight of the Company’s human capital management strategies, policies, and initiatives. The Environmental and Social Responsibility Committee is periodically updated on employee engagement, learning and development programs, culture and workplace safety. The Compensation Committee, which is advised by an independent compensation consultant, is responsible for the oversight of management development and evaluation of succession planning for senior management, and a review of the Company’s compensation programs and practices, including senior management compensation benchmarked against a comparison group.

Tax Matters

United States Tax Reform

The Tax Cuts and Jobs Act of 2017 (the TCJA) lowered the corporate U.S. tax rate to 21%, eliminated the alternative minimum tax, limited the deductibility of interest expense and required a one-time tax on a deemed repatriation of untaxed earnings of non-U.S. subsidiaries. In the context of the taxation of U.S. property/casualty insurance companies such as the Company, the TCJA also modifies the loss reserve discounting rules and the proration rules that apply to reduce reserve deductions to reflect the lower corporate income tax rate. In addition, the TCJA included certain provisions intended to eliminate certain perceived tax advantages of companies (including insurance companies) that have legal domiciles outside the U.S. but have certain U.S. connections and U.S. persons investing in such companies. For example, the TCJA includes a base erosion and anti-abuse tax that could make affiliate reinsurance between U.S. and non-U.S. members of the Company’s group economically unfeasible. In addition, the TCJA introduced a current tax on global intangible low-taxed income that may result in an increase in U.S. corporate income tax imposed on the Company’s U.S. group members with respect to earnings of their non-U.S. subsidiaries. As discussed in more detail below, the TCJA also revised the rules applicable to passive foreign investment companies (PFICs) and controlled foreign corporations (CFCs). On July 4, 2025, the U.S. Congress passed budget reconciliation bill H.R. 1 referred to as the One Big Beautiful Bill Act (OBBBA). The OBBBA includes significant provisions, such as the permanent extension of certain expiring provisions of the TCJA, modifications to the international tax framework and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates, with certain provisions effective in 2025 and others implemented through 2027. The Company is currently assessing the impact on its consolidated financial statements, but does not expect it to have a material impact. Further, it is possible that other legislation could be introduced and enacted by the current Congress or future Congresses that could have an adverse impact on the Company. Additionally, tax laws and interpretations regarding whether a company is engaged in a U.S. trade or business or whether a company is a CFC or a PFIC or has related person insurance income (RPII) are subject to change, possibly on a retroactive basis. The U.S. Department of the Treasury issued final and proposed regulations intended to clarify the application of the insurance income exception to the classification of a non-U.S. insurer as a PFIC and provide guidance on a range of issues relating to PFICs, and issued proposed regulations that would expand the scope of the RPII rules. New regulations or pronouncements interpreting or clarifying such rules may be forthcoming. The Company 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. See Part II, Item 8. Financial Statements and Supplementary Data, Note 13. Income Taxes.

Taxation of AGL and Subsidiaries

Bermuda

On December 27, 2023, the Government of Bermuda enacted the Corporate Income Tax Act 2023 (the CIT Act), which imposes a corporate income tax at the rate of 15% to in-scope entities for accounting periods starting on or after January

1, 2025. Entities subject to tax under the CIT Act are the Bermuda tax resident entities of multinational groups that have annual revenues of €750 million or greater for at least two of the last four fiscal years.

However, a Bermuda tax resident’s entity’s liability under the CIT Act is subject to the application of any foreign tax credits (FTC) that may arise if the entity’s income is taxed in a jurisdiction outside Bermuda. The CIT Act also contains a number of adjustments to an entity’s net income for tax purposes, including transitional adjustments such as the economic transition adjustment (ETA) which, broadly, permits certain deferred tax assets to be utilized against future liabilities as a result of a step-up in the tax basis of certain assets and liabilities as of September 30, 2023 for those entities that are (or will be) subject to the CIT Act but were Bermuda tax resident as of the step-up date. Under the CIT Act of Bermuda, any liability for the tax will apply regardless of any assurances previously provided under the Exempted Undertakings Tax Protection Act 1966 of Bermuda.

United States

AGL has conducted and intends to continue to conduct substantially all of its operations outside the U.S. and to limit the U.S. contacts of AGL and its non-U.S. subsidiaries (except for its non-U.S. subsidiaries that elect to be taxed as a U.S. corporation) so that they should not be engaged in a trade or business in the U.S. A non-U.S. corporation, such as AG Re, that is deemed to be engaged in a trade or business in the U.S. would be subject to U.S. income tax at regular corporate rates, as well as the branch profits tax, on its income which is treated as effectively connected with the conduct of that trade or business, unless the corporation is entitled to relief under the permanent establishment provision of an applicable tax treaty, as discussed below. Such income tax, if imposed, would be based on effectively connected income computed in a manner generally analogous to that applied to the income of a U.S. corporation, except that a non-U.S. corporation would generally be entitled to deductions and credits only if it timely files a U.S. federal income tax return. AGL, AG Re and certain of the other non-U.S. subsidiaries have filed and will continue to file protective U.S. federal income tax returns on a timely basis in order to preserve the right to claim income tax deductions and credits if it is ever determined that they are subject to U.S. federal income tax. The highest marginal federal income tax rates currently are 21% for a corporation’s effectively connected income and 30% for the “branch profits” tax.

Under the income tax treaty between Bermuda and the U.S. (the Bermuda Treaty), a Bermuda insurance company would not be subject to U.S. income tax on income found to be effectively connected with a U.S. trade or business unless that trade or business is conducted through a permanent establishment in the U.S. AG Re currently intends to conduct its activities so that it does not have a permanent establishment in the U.S.

An insurance enterprise resident in Bermuda generally will be entitled to the benefits of the Bermuda Treaty if: (i) more than 50% of its shares are owned beneficially, directly or indirectly, by individual residents of the U.S. or Bermuda or U.S. citizens; and (ii) its income is not used in substantial part, directly or indirectly, to make disproportionate distributions to, or to meet certain liabilities of, persons who are neither residents of either the U.S. or Bermuda nor U.S. citizens.

Non-U.S. insurance companies carrying on an insurance business within the U.S. have a certain minimum amount of effectively connected net investment income determined in accordance with a formula that depends, in part, on the amount of U.S. risk insured or reinsured by such companies. If AG Re or another of the Company’s Bermuda subsidiaries is considered to be engaged in the conduct of an insurance business in the U.S. and is not entitled to the benefits of the Bermuda Treaty in general (because it fails to satisfy one of the limitations on treaty benefits discussed above), the Internal Revenue Code of 1986, as amended (the Code), could subject a significant portion of AG Re’s or another of the Company’s Bermuda subsidiary’s investment income to U.S. income tax.

AGL, as a U.K. tax resident, would not be subject to U.S. income tax on any income found to be effectively connected with a U.S. trade or business under the income tax treaty between the U.S. and the U.K. (the U.K. Treaty), unless that trade or business is conducted through a permanent establishment in the U.S. AGL intends to conduct its activities so that it does not have a permanent establishment in the U.S.

Non-U.S. corporations not engaged in a trade or business in the U.S., and those that are engaged in a U.S. trade or business with respect to their non-effectively connected income are nonetheless subject to U.S. withholding tax on certain “fixed or determinable annual or periodic gains, profits and income” derived from sources within the U.S. (such as dividends and certain interest on investments), subject to exemption under the Code or reduction by applicable treaties. The standard non-treaty rate of U.S. withholding tax is currently 30%. The Bermuda Treaty does not reduce the U.S. withholding rate on U.S.-sourced investment income. The U.K. Treaty reduces or eliminates U.S. withholding tax on certain U.S.-sourced investment income, including dividends from U.S. companies to U.K. resident persons entitled to the benefit of the U.K. Treaty.

The U.S. also imposes an excise tax on insurance and reinsurance premiums paid to non-U.S. insurers with respect to risks of a U.S. person located wholly or partly within the U.S. or risks of a foreign person engaged in a trade or business in the U.S. which are located within the U.S. The rates of tax applicable to premiums paid are 4% for direct casualty insurance premiums and 1% for reinsurance premiums.

AGRO has elected to be treated as a U.S. corporation for all U.S. federal tax purposes and, as such, AGRO, together with AGL’s U.S. subsidiaries, is subject to taxation in the U.S. at regular corporate rates.

The Company is currently evaluating the U.S. federal tax purpose of Assured Life Re.

If AGRO were to pay dividends to its U.S. holding company parent and that U.S. holding company were to pay dividends to its Bermudian parent AG Re, such dividends would be subject to U.S. withholding tax at a rate of 30%.

United Kingdom

In November 2013, AGL became tax resident in the U.K. AGL remains a Bermuda-based company and its administrative and head office functions continue to be carried on in Bermuda. The AGL common shares have not changed and continue to be listed on the New York Stock Exchange (NYSE).

As a company that is not incorporated in the U.K., AGL will be considered tax resident in the U.K. only if it is “centrally managed and controlled” in the U.K. Central management and control constitutes the highest level of control of a company’s affairs. From November 6, 2013, AGL’s Board began to manage the affairs of AGL in such a way as to maintain its status as a company that is tax resident in the U.K.

As a U.K. tax resident company, AGL is subject to the tax rules applicable to companies resident in the U.K., including the benefits afforded by the U.K.’s tax treaties.

As a U.K. tax resident, AGL is required to file a corporation tax return with His Majesty’s Revenue & Customs (HMRC). AGL is subject to U.K. corporation tax in respect of its worldwide profits (both income and capital gains), subject to any applicable exemptions. The main rate of corporation tax is currently 25%. AGL has also registered in the U.K. to report its value-added tax (VAT) liability. The current standard rate of VAT is 20%. Further, with effect for accounting periods starting on or after December 31, 2023, AGL may be liable to charges under the U.K.’s multinational top-up tax to the extent that any member (or members) of the group is resident in a territory other than the U.K. and that member (or those members, collectively) has an effective tax rate of less than 15% in that territory. Alternatively, AGL may be liable to charges under the U.K.’s domestic top-up tax if profits arising in the U.K. are taxed at a rate of less than 15%.

The dividends AGL receives from its direct subsidiaries should be exempt from U.K. corporation tax due to the exemption in section 931D of the U.K. Corporation Tax Act 2009. In addition, any dividends paid by AGL to its shareholders should not be subject to any withholding tax in the U.K. The non-U.K. resident subsidiaries intend to operate in such a manner that their profits are outside the scope of the charge under the “controlled foreign companies” regime. Accordingly, Assured Guaranty does not expect any profits of non-U.K. resident members of the group to be attributed to AGL and taxed in the U.K. under the CFC regime. In 2013, Assured Guaranty obtained clearance from HMRC confirming this on the basis of the facts and intentions as they were at the time.

The U.K. enacted legislation in July 2023 and February 2024, and HMRC published guidance in respect of such legislation, which, broadly, implements the Organization for Economic Co-operation and Development (OECD) Model Rules for Pillar Two into U.K. domestic legislation for accounting periods starting on or after December 31, 2023. Pillar Two comprises rules granting jurisdictions additional taxing rights where other relevant jurisdictions have either not taxed relevant profits or those profits have been subject to a rate of tax below 15%. The rules apply to multinational groups with consolidated group revenue of €750 million or more in at least two out of the preceding four fiscal years. Through a series of complex interlocking rules, the intended effect is that low or no taxed profits would be subject to tax at an overall rate of at least 15%. See Item 1A. Risk Factors — Risks Related to Taxation captioned “AGL may become, and AG Re and AGRO are, subject to taxes in Bermuda, which may adversely affect the Company’s future results of operations and an investment in the Company” and “Assured Guaranty’s financial results may be affected by measures taken in response to the OECD BEPS project.”

Taxation of Shareholders

Bermuda Taxation

Currently, there is no Bermuda capital gains tax, or withholding or other tax payable on principal, interest or dividends paid to the holders of the AGL common shares.

United States Taxation

This discussion is based upon the Code, the regulations promulgated thereunder and any relevant administrative rulings or pronouncements or judicial decisions, all as in effect on the date of filing 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 U.S. or any foreign government.

The following summary sets forth the material U.S. federal income tax considerations related to the purchase, ownership and disposition of AGL’s shares. Unless otherwise stated, this summary deals only with holders that are U.S. Persons (as defined below) who purchase and hold their shares and who hold their shares as capital assets within the meaning of section 1221 of the Code. 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. For example, special rules apply to certain shareholders, such as partnerships, insurance companies, regulated investment companies, real estate investment trusts, dealers or traders in securities, tax exempt organizations, expatriates, persons liable for alternative minimum tax, U.S. accrual method taxpayers subject to special tax accounting rules as a result of any item of gross income with respect to AGL’s shares being taken into account in an applicable financial statement as described in section 451(b) of the Code, persons that do not hold their securities in the U.S. dollar, persons who are considered with respect to AGL or any of its non-U.S. subsidiaries as “United States shareholders” for purposes of the CFC rules of the Code (generally, a U.S. Person, as defined below, who owns or is deemed to own 10% or more of the total combined voting power or value of all classes of AGL shares or the shares of any of AGL’s non-U.S. subsidiaries (i.e., 10% U.S. Shareholders)), or persons who hold the common shares as part of a hedging or conversion transaction or as part of a short-sale or straddle or other integrated transaction. Any such shareholder should consult their tax adviser.

If a partnership holds AGL’s shares, the tax treatment of the partners will generally depend on the status of the partner and the activities of the partnership. Partners of a partnership owning AGL’s shares should consult their tax advisers.

For purposes of this discussion, the term “U.S. Person” means: (i) a citizen or resident of the U.S.; (ii) a partnership or corporation, created or organized in or under the laws of the U.S., or organized under 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 U.S. 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 Distributions. Subject to the discussions below relating to the potential application of the CFC, RPII and PFIC rules, cash distributions, if any, made with respect to AGL’s shares will constitute dividends for U.S. federal income tax purposes to the extent paid out of current or accumulated earnings and profits of AGL (as computed using U.S. tax principles). Dividends paid by AGL to corporate shareholders will not be eligible for the dividends received deduction. To the extent such distributions exceed AGL's earnings and profits, they will be treated first as a return of the shareholder’s basis in the common shares to the extent thereof, and then as gain from the sale of a capital asset.

AGL believes dividends paid by AGL on its common shares to non-corporate holders will be eligible for reduced rates of tax at the rates applicable to long-term capital gains as “qualified dividend income,” provided that AGL is not a PFIC and certain other requirements, including stock holding period requirements, are satisfied.

Classification of AGL or its Non-U.S. Subsidiaries as a CFC. Each 10% U.S. Shareholder (as defined below) of a non-U.S. corporation that is a CFC at any time during a taxable year that owns, directly or indirectly through non-U.S. entities, shares in the non-U.S. corporation on the last day of the non-U.S. corporation’s taxable year on which it is a CFC, must include in its gross income, for U.S. federal income tax purposes, its pro rata share of the CFC’s “subpart F income,” even if the subpart F income is not distributed. “Subpart F income” of a non-U.S. insurance corporation typically 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). A non-U.S. corporation is considered a CFC if 10% U.S. Shareholders own (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)) more than 50% of the total combined voting power of all classes of voting stock of such non-U.S. corporation, or more than 50% of the total value of all stock of such corporation on any day during the taxable year of such corporation. For purposes of taking into account insurance income, a CFC also includes a non-U.S. corporation in which more than 25% of the total combined voting power of all classes of stock or more than 25% of the total value of the stock is owned by 10% U.S. Shareholders, on any day during the taxable year of such corporation. A “10% U.S. Shareholder” is a U.S. Person who owns (directly, indirectly through non-U.S. entities or constructively) at least 10% of the total combined voting power or value of all classes of stock of the non-U.S. corporation. The TCJA expanded the definition of 10% U.S. Shareholder to include ownership by value (rather than just vote), so provisions in the Company’s organizational documents that cut back voting power to potentially avoid 10% U.S. Shareholder status will no longer mitigate the risk of 10% U.S. Shareholder status. AGL believes that because of the dispersion of AGL’s share ownership, no U.S. Person who owns shares of AGL directly or indirectly through one or more non-U.S. entities should be treated as owning (directly, indirectly through non-U.S. entities, or constructively), 10% or more of the total voting power or value of all classes of shares of AGL or any of its non-U.S. subsidiaries. However, AGL’s shares may not be as widely dispersed as the Company believes due to, for example, the application of certain ownership attribution rules, and no assurance may be given that a U.S. Person who owns the Company's shares will not be characterized as a 10% U.S. Shareholder. In addition, the direct and indirect subsidiaries of AGUS are characterized as CFCs and any subpart F income generated will be included in the gross income of the applicable domestic subsidiaries in the AGL group.

The RPII CFC Provisions. The following discussion generally is applicable only if the gross RPII of AG Re or any other non-U.S. insurance subsidiary that either: (i) has not made an election under section 953(d) of the Code to be treated as a U.S. corporation for all U.S. federal tax purposes or (ii) is not a CFC owned directly or indirectly by AGUS (each, a Foreign Insurance Subsidiary, or collectively, with AG Re, the Foreign Insurance Subsidiaries) is 20% or more of the Foreign Insurance Subsidiary’s gross insurance income for the taxable year and the 20% Ownership Exception (as defined below) is not met. The following discussion generally would not apply for any taxable year in which the Foreign Insurance Subsidiary’s gross RPII falls below the 20% threshold or the 20% Ownership Exception is met. Although the Company cannot be certain, it believes that each Foreign Insurance Subsidiary has been, in prior years of operations, and will be, for the foreseeable future, either below the 20% threshold or in compliance with the requirements of 20% Ownership Exception for each tax year.

RPII is any “insurance income” (as defined below) attributable to policies of insurance or reinsurance with respect to which the person (directly or indirectly) insured is a “RPII shareholder” (as defined below) or a “related person” (as defined below) to such 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 domestic insurance company. For purposes of inclusion of the RPII of a Foreign Insurance Subsidiary in the income of RPII shareholders, unless an exception applies, the term "RPII shareholder" means any U.S. Person who owns (directly or indirectly through non-U.S. entities) any amount of AGL’s common shares. Generally, the term “related person” for this purpose means someone who controls or is controlled by the RPII shareholder or someone who is controlled by the same person or persons which control the RPII shareholder. Control is measured by either more than 50% in value or more than 50% in voting power of stock applying certain constructive ownership principles. A Foreign Insurance Subsidiary will be treated as a CFC under the RPII provisions if RPII shareholders are treated as owning (directly, indirectly through non-U.S. entities or constructively) 25% or more of the shares of AGL by vote or value.

RPII Exceptions. The special RPII rules do not apply if: (i) at all times during the taxable year less than 20% of the voting power and less than 20% of the value of the stock of AGL (the 20% Ownership Exception) is owned (directly or indirectly through entities) by persons who are (directly or indirectly) insured under any policy of insurance or reinsurance issued by a Foreign Insurance Subsidiary or related persons to any such person; (ii) RPII, determined on a gross basis, is less than 20% of a Foreign Insurance Subsidiary’s gross insurance income for the taxable year (the 20% Gross Income Exception); (iii) a Foreign Insurance Subsidiary elects to be taxed on its RPII as if the RPII were effectively connected with the conduct of a U.S. trade or business, and to waive all treaty benefits with respect to RPII and meet certain other requirements; or (iv) a Foreign Insurance Subsidiary elects to be treated as a U.S. corporation and waive all treaty benefits and meet certain other requirements. The Foreign Insurance Subsidiaries do not intend to make either of these elections. Where none of these exceptions applies, each U.S. Person owning or treated as owning any shares in AGL (and therefore, indirectly, in a Foreign Insurance Subsidiary) on the last day of AGL’s taxable year will be required to include in its gross income for U.S. federal income tax purposes its share of the RPII for the portion of the taxable year during which a Foreign Insurance Subsidiary was a CFC under the RPII provisions, determined as if all such RPII were distributed proportionately only to such U.S. Persons at that date, but limited by each such U.S. Person’s share of a Foreign Insurance Subsidiary’s current-year earnings and profits as reduced by the U.S. Person’s share, if any, of certain prior-year deficits in earnings and profits. The Foreign Insurance

Subsidiaries intend to operate in a manner that is intended to ensure that each qualifies for either the 20% Gross Income Exception or 20% Ownership Exception.

Computation of RPII. For any year in which a Foreign Insurance Subsidiary does not meet the 20% Ownership Exception or the 20% Gross Income Exception, AGL may also seek information from its shareholders as to whether beneficial owners of 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 AGL is unable to determine whether a beneficial owner of shares is a U.S. Person, AGL may assume that such owner is not a U.S. Person, thereby increasing the per share RPII amount for all known RPII shareholders. The amount of RPII includable in the income of a RPII shareholder is based upon the net RPII income for the year after deducting related expenses such as losses, loss reserves and operating expenses. If a Foreign Insurance Subsidiary meets the 20% Ownership Exception or the 20% Gross Income Exception, RPII shareholders will not be required to include RPII in their taxable income.

Apportionment of RPII to U.S. Holders. Every RPII shareholder who owns shares on the last day of any taxable year of AGL in which a Foreign Insurance Subsidiary does not meet the 20% Ownership Exception or the 20% Gross Income Exception should expect that for such year it will be required to include in gross income its share of a Foreign Insurance Subsidiary's RPII for the portion of the taxable year during which the Foreign Insurance Subsidiary was a CFC under the RPII provisions, whether or not distributed, even though it may not have owned the shares throughout such period. A RPII shareholder who owns shares during such taxable year but not on the last day of the taxable year is not required to include in gross income any part of the Foreign Insurance Subsidiary’s RPII.

Basis Adjustments. A RPII shareholder’s tax basis in its common shares will be increased by the amount of any RPII the shareholder includes in income. The RPII shareholder may exclude from income the amount of any distributions by AGL out of previously taxed RPII income. The RPII shareholder’s tax basis in its common shares will be reduced by the amount of such distributions that are excluded from income.

Uncertainty as to Application of RPII. The RPII provisions are complex and have never been interpreted by the courts or the Treasury Department in final regulations; regulations interpreting the RPII provisions of the Code exist only in proposed form. Further, proposed regulations could, if finalized in their current form, substantially expand the definition of RPII to include insurance income of our Foreign Insurance Subsidiaries related to affiliate reinsurance transactions. These regulations would apply to taxable years beginning after the date the regulations are finalized. Although we cannot predict whether, when or in what form the proposed regulations might be finalized, the proposed regulations, if finalized in their current form, could limit our ability to execute affiliate reinsurance transactions that would otherwise be undertaken for non-tax business reasons in the future and could increase the risk that gross RPII could constitute 20% or more of the gross insurance income of one or more of our Foreign Insurance Subsidiaries in a particular taxable year, which could result in such RPII being taxable to U.S. Persons that own or are treated as owning shares of AGL. Accordingly, the meaning of the RPII provisions and the application thereof to the Foreign Insurance Subsidiaries is uncertain. In addition, the Company cannot be certain that the amount of RPII or the amounts of the RPII inclusions for any particular RPII shareholder, if any, will not be subject to adjustment based upon subsequent Internal Revenue Service (IRS) examination. U.S. Persons owning or treated as owning shares of AGL should consult their tax advisors as to the effect of these uncertainties.

Information Reporting. Under certain circumstances, U.S. Persons owning shares (directly, indirectly or constructively) in a non-U.S. corporation are required to file IRS Form 5471, Information Return of U.S. Persons With Respect To Certain Foreign Corporations, 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 RPII shareholder; (ii) a 10% U.S. Shareholder of a non-U.S. corporation that is a CFC at any time during any tax year of the non-U.S. corporation and who owned the stock on the last day of that year; 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. For any taxable year in which AGL determines that neither the 20% Gross Income Exception nor the 20% Ownership Exception applies, AGL will provide to all U.S. Persons registered as shareholders of its shares a completed IRS Form 5471 or the relevant information necessary to complete the form. Failure to file IRS Form 5471 may result in penalties. In addition, U.S. shareholders should consult their tax advisers with respect to other information reporting requirements that may be applicable to them.

U.S. Persons holding the Company’s shares should consider their possible obligation to file FinCEN Form 114, Foreign Bank and Financial Accounts Report, with respect to their shares. Additionally, such U.S. and non-U.S. persons should consider their possible obligations to annually report certain information with respect to the non-U.S. accounts with their U.S. federal income tax returns. Shareholders should consult their tax advisers with respect to these or any other reporting requirement which may apply with respect to their ownership of the Company’s shares.

Tax-Exempt Shareholders. Tax-exempt entities will be required to treat certain subpart F insurance income, including RPII, that is includable in income by the tax-exempt entity as unrelated business taxable income. Prospective investors that are tax exempt entities are urged to consult their tax advisers 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 RPII Shareholder also must file IRS Form 5471 in certain circumstances.

Dispositions of AGL’s Shares. Subject to the discussions below relating to the potential application of the Code section 1248 and PFIC rules, holders of shares generally should recognize capital gain or loss for U.S. federal income tax purposes on the sale, exchange or other disposition of shares in the same manner as on the sale, exchange or other disposition of any other shares held as capital assets. If the holding period for these shares exceeds one year, any gain will be subject to tax at the marginal tax rate applicable to long term capital gains.

Code 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 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). The Company believes that because of the dispersion of AGL’s share ownership, no U.S. shareholder of AGL should be treated as owning (directly, indirectly through non-U.S. entities or constructively) 10% or more of the total voting power of AGL; to the extent this is the case this application of Code Section 1248 under the regular CFC rules should not apply to dispositions of AGL’s shares. 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, AGL will provide a completed IRS Form 5471 or the relevant information necessary to complete the Form. Code section 1248 in conjunction with the RPII rules also applies to the sale or exchange of shares in a non-U.S. corporation if the non-U.S. corporation would be treated as a CFC for RPII purposes regardless of whether the shareholder is a 10% U.S. Shareholder or whether the 20% Ownership Exception or 20% Gross Income Exception applies. Existing proposed regulations do not address whether Code section 1248 would apply if a non-U.S. corporation is not a CFC 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 U.S. domestic corporation. The Company believes, however, that this application of Code section 1248 under the RPII rules should not apply to dispositions of AGL’s shares because AGL will not be directly engaged in the insurance business. The Company cannot be certain, however, that the IRS will not interpret the proposed regulations in a contrary manner or that the Treasury Department will not amend the proposed regulations to provide that these rules will apply to dispositions of common shares. Prospective investors should consult their tax advisers regarding the effects of these rules on a disposition of common 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 passive income (the 50% test) and once characterized as a PFIC will generally retain PFIC status for future taxable years with respect to its U.S. shareholders in the taxable year of the initial PFIC characterization.

If AGL were characterized as a PFIC during a given year, each U.S. Person holding AGL’s shares 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 shares, unless such person: (i) is a 10% U.S. Shareholder and AGL is a CFC; or (ii) made a “qualified electing fund election” or “mark-to-market” election. It is uncertain that AGL 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 AGL were considered a PFIC, upon the death of any U.S. individual owning common shares, such individual’s heirs or estate would not be entitled to a “step-up” in the basis of the common 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 common shares during the three preceding taxable years (or shorter period during which the taxpayer held common shares). In general, the penalty tax is equivalent to an interest charge on taxes that are deemed due during the period the shareholder owned the common shares, computed by assuming that the excess distribution or gain (in the case of a sale) with respect to the common shares was taken in equal portion at the highest applicable tax rate on ordinary income throughout the shareholder's period of ownership. The interest charge is equal to the applicable rate imposed on underpayments of U.S. federal income tax for such period. In addition, a distribution paid by AGL 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. A U.S. Person that is a shareholder in a PFIC may also be subject to additional information reporting requirements, including the annual filing of IRS Form 8621, Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund.

For the above purposes, passive income generally includes interest, dividends, annuities and other investment income. The PFIC rules, as amended by the TCJA, provide that income derived in the active conduct of an insurance business by a qualifying insurance corporation is not treated as passive income. The PFIC provisions also contain a look-through rule under which a non-U.S. corporation shall be treated as if it “received directly its proportionate share of the income...” and as if it “held its proportionate share of the assets...” of any other corporation in which it owns at least 25% of the value of the stock. A second PFIC look-through rule would treat stock of a U.S. corporation owned by another U.S. corporation which is at least 25% owned (by value) by a non-U.S. corporation as a non-passive asset that generates non-passive income for purposes of determining whether the non-U.S. corporation is a PFIC.

The insurance income exception originally was intended to ensure that income derived by a bona fide insurance company is not treated as passive income, except to the extent such income is attributable to financial reserves in excess of the reasonable needs of the insurance business. The Company expects, for purposes of the PFIC rules, that each of AGL’s insurance subsidiaries is unlikely to have financial reserves in excess of the reasonable needs of its insurance business in each year of operations. However, the TCJA limits the insurance income exception to a non-U.S. insurance company that is a qualifying insurance corporation that would be taxable as an insurance company if it were a U.S. corporation and maintains insurance liabilities of more than 25% of such company’s assets for a taxable year (or maintains insurance liabilities that at least equal or exceed 10% of its assets, is predominantly engaged in an insurance business and satisfies a facts and circumstances test that requires a showing that the failure to exceed the 25% threshold is due to runoff-related or rating-related circumstances) (the Reserve Test). Further, the U.S. Treasury Department and the IRS issued final and proposed regulations (the 2020 Regulations) intended to clarify the application of the PFIC provisions to a non-U.S. insurance company and provide guidance on a range of issues relating to PFICs, including the application of the look-through rule, the treatment of income and assets of certain U.S. insurance subsidiaries for purposes of the look-through rule and the extension of the look-through rule to 25% or more owned partnerships. The 2020 Regulations define insurance liabilities for purposes of the Reserve Test, tighten the Reserve Test and the statutory cap on insurance liabilities, and provide guidance on the runoff-related and rating-related circumstances for purposes of the 10% test (including a provision that deems certain financial guaranty insurers that fail the 25% test to meet the rating-related circumstances test). The 2020 Regulations also propose that a non-U.S. insurance company will qualify for the insurance company exception only if a factual requirements test or an active conduct percentage test is satisfied. The factual requirements test will be met if the non-U.S. insurance company’s officers and employees perform its substantial managerial and operational activities on a regular and continuous basis with respect to its core functions and virtually all of the active decision-making functions relevant to underwriting on a contract-by-contract basis (taking into account activities of officers and employees of certain related entities in certain cases). The active conduct percentage test will be satisfied if: (1) the total costs incurred by the non-U.S. insurance company with respect to its officers and employees (including officers and employees of certain related entities) for services related to core functions (other than investment activities) equal at least 50% of the total costs incurred for all such services; and (2) the non-U.S. insurer’s officers and employees oversee any part of the non-U.S. insurance company’s core functions, including investment management, that are outsourced to an unrelated party. Services provided by officers and employees of certain related entities are only taken into account in the numerator of the active conduct percentage if the non-U.S. insurance company exercises regular oversight and supervision over such services and compensation arrangements meet certain requirements. The 2020 Regulations also propose that a non-U.S. insurance company with no or a nominal number of employees that relies exclusively or almost exclusively upon independent contractors (other than certain related entities) to perform its core functions will not be treated as engaged in the active conduct of an insurance business. The Company believes that, based on the application of the PFIC look-through rules described above and the Company's plan of operations for the current and future years, AGL should not be characterized as a PFIC. However, as the Company cannot predict the likelihood of finalization of the proposed 2020 Regulations or the scope, nature or impact of the 2020 Regulations on us, or whether the Company’s non-U.S. insurance subsidiaries will be able to satisfy the Reserve Test in future years and the interaction of the PFIC look-through rules is not clear, no assurance may be given that the Company will not be characterized as a PFIC. Prospective investors should consult their tax adviser as to the effects of the PFIC rules.

Foreign tax credit. If U.S. Persons own a majority of AGL’s common shares, only a portion of the current income inclusions, if any, under the CFC, RPII and PFIC rules and of dividends paid by AGL (including any gain from the sale of common 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. The Company 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 either “passive” or “general” income. Thus, it may not be possible for most shareholders to utilize excess FTC to reduce U.S. tax on such income.

Information Reporting and Backup Withholding on Distributions and Disposition Proceeds. Information returns may be filed with the IRS in connection with distributions on AGL’s common shares and the proceeds from a sale or other disposition of AGL’s common shares unless the holder of AGL’s common shares establishes an exemption from the

information reporting rules. A holder of common 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 non-U.S. Person 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.

United Kingdom

The following discussion is intended to be only a general guide to certain U.K. tax consequences of holding AGL common shares, under current law and the current practice of HMRC, either of which is subject to change at any time, possibly with retrospective effect. Except where otherwise stated, this discussion applies only to shareholders who are not (and have not recently been) resident or (in the case of individuals) domiciled for tax purposes in the U.K. who hold their AGL common shares as an investment and who are the absolute beneficial owners of their common shares. This discussion may not apply to certain shareholders, such as dealers in securities, life insurance companies, collective investment schemes, shareholders who are exempt from tax and shareholders who have (or are deemed to have) acquired their shares by virtue of an office or employment. Such shareholders may be subject to special rules.

The following statements do not purport to be a comprehensive description of all the U.K. considerations that may be relevant to any particular shareholder. Any person who is in any doubt as to their tax position should consult an appropriate professional tax adviser.

AGL’s Tax Residency. AGL is not incorporated in the U.K., but from November 6, 2013, AGL’s Board has managed its affairs with the intent to maintain its status as a company that is tax resident in the U.K.

Dividends. Under current U.K. tax law, AGL is not required to withhold tax at source from dividends paid to the holders of the AGL common shares.

Capital gains. U.K. tax is not normally charged on any capital gains realized by non-U.K. shareholders in AGL unless, in the case of a corporate shareholder, at or before the time the gain accrues, the shareholding is used in or for the purposes of a trade carried on by the non-resident shareholder through a permanent establishment in the U.K. or for the purposes of that permanent establishment. Similarly, an individual shareholder who carries on a trade, profession or vocation in the U.K. through a branch or agency may be liable for U.K. tax on the gain if such shareholder disposes of shares that are, or have been, used, held or acquired for the purposes of such trade, profession or vocation or for the purposes of such branch or agency. This treatment applies regardless of the U.K. tax residence status of AGL.

Stamp Taxes. On the basis that AGL does not currently intend to maintain a share register in the U.K., there should be no U.K. stamp duty reserve tax on a purchase of common shares in AGL. A conveyance or transfer on sale of common shares in AGL will not be subject to U.K. stamp duty, provided that the instrument of transfer is not executed in the U.K. and does not relate to any property situated, or any matter or thing done, or to be done, in the U.K.

Risks Related to Economic, Market and Political Conditions and Natural Phenomena

Developments in the global financial markets, political systems and the economy generally may adversely affect the Company’s financial condition, results of operations, capital, liquidity, business prospects and share price.

In recent years, global financial markets, political systems and the economy generally have been impacted by changes in inflation and interest rates, governmental policies such as tariffs, and geopolitical events, including regional and global military conflicts and strategic competition and trade confrontations, and could be impacted by other natural and man-made events in the future.

These and other risks could materially and negatively affect the Company’s ability to access the capital markets, the cost of the Company’s debt, the demand for its credit enhancement products, the amount of losses incurred on transactions it guarantees, the value and performance of its investments, the Company’s earnings from its ownership interest in Sound Point, the capital and liquidity position and financial strength and enhancement ratings of its insurance subsidiaries, and the price of its common shares.

Public finance obligors that have issued obligations insured or reinsured by the Company are experiencing, or may in the future experience, significant budget deficits, and pension and revenue shortfalls, and difficulties in obtaining additional financing, that could result in increased credit losses or liquidity claims and increased rating agency capital charges on those insured obligations.

Certain territorial or local governments, including ones that have issued obligations insured or reinsured by the Company, have sought protection from creditors under Chapter 9 of the U.S. Bankruptcy Code, or, in the case of Puerto Rico, the similar provisions of the Puerto Rico Oversight, Management, and Economic Stability Act (PROMESA), as a means of restructuring their outstanding debt. In some instances where local governments were are seeking to restructure their outstanding debt, pension and other obligations owed to workers were treated more favorably than senior bond debt owed to the capital markets. If the issuers of the obligations in the Company’s public finance portfolio do not have sufficient funds to cover their expenses and are unable or unwilling to raise taxes, decrease spending, or receive federal assistance, the Company may experience increased levels of losses or liquidity claims on its insured public finance obligations.

Obligations supported by revenue streams, which may include both revenue and non-revenue bonds, such as those issued by healthcare facilities, toll road authorities, municipal utilities, airport authorities or mass transit, may be adversely affected by revenue declines resulting from reduced demand, changing demographics, evolving business practices including hybrid work models, telecommuting and other alternative work arrangements, reduced governmental aid, or other causes. These obligations may also be adversely affected by increased costs resulting from operational strain, high financing costs and other capital constraints. These obligations, which may not necessarily benefit from financial support from other tax revenues or governmental authorities, may experience increased losses if the revenue streams are insufficient to pay scheduled debt service and the obligors are unable or unwilling to increase utility rates or revenues, decrease costs, or obtain other additional financing.

The Company may be subjected to significant risks from large individual or correlated financial guaranty insurance exposures.

The Company is exposed to the risk that issuers of obligations that it insures or other counterparties may default on their financial obligations, whether as a result of insolvency, lack of liquidity, operational failure (whether related to cybersecurity incidents, mismanagement, fraud or otherwise) or other reasons, and the amount of financial guaranty insurance exposure the Company has to some risks is quite large. The Company seeks to reduce this risk by managing exposure to large single risks, as well as concentrations of correlated risks, through tracking its aggregate exposure to single risks in its various lines of financial guaranty insurance business and establishing underwriting criteria to manage risk aggregations. However, in certain cases, the Company’s ultimate exposure to a single risk may exceed its underwriting guidelines (caused by, for example, bond accretion exceeding the risk limitation, acquisitions, reassumptions or other strategic exceptions). Additionally, certain lines of business written by the Company have short durations of less than one year and a systemic event could cause the Company to have losses in excess of available liquidity. Should the Company's risk assessments prove inaccurate and/or should the applicable limits prove inadequate, the Company could be exposed to larger than anticipated losses, could be required by the rating agencies to hold additional capital against insured exposures whether or not the insured obligations are downgraded by the rating agencies, and external financing may or may not be available to the Company in the future on satisfactory terms.

The Company is exposed to correlation risk across its insured exposures and in its investment portfolio. During periods of strong macroeconomic performance, stress in an individual transaction generally occurs for idiosyncratic reasons or as a result of issues in a single sector. During a broad economic downturn or in the face of a significant natural or man-made event

or disaster, a wider range of the Company’s insurance and investments could be exposed to stress at the same time. This stress may manifest itself in any or all of the following: ratings downgrades of insured risks, which may require more capital in the Company’s insurance subsidiaries; ratings downgrades of the Company’s insurance or reinsurance subsidiaries; a reduction in the value of the Company’s investments; and actual defaults and losses in its insurance portfolio and/or investments.

Losses on obligations insured by the Company significantly in excess of those expected by the Company or recoveries significantly below those expected by the Company could have a negative effect on the Company’s financial condition, results of operations, capital, business prospects and share price.

Losses on insured exposures significantly in excess of those expected by the Company could have a negative effect on the Company’s financial condition, results of operations, capital, business prospects and share price. Certain issuers have defaulted on their debt service payments, and the Company has paid claims on them. The total net expected loss the Company calculates related to such exposures is net of credit for estimated recoveries on claims already paid, and recoveries significantly below those expected by the Company could also have a negative effect on the Company’s financial condition, results of operations, capital, liquidity, business prospects and share prices. Additional information about the Company’s exposure and legal actions related to that exposure may be found in Part II, Item 8. Financial Statements and Supplementary Data, Note 4. Expected Loss to be Paid (Recovered).

A higher U.S. debt-to-GDP ratio and/or downgrades to the U.S. government’s sovereign credit ratings, or to the credit ratings of instruments issued, insured or guaranteed by related institutions, agencies or instrumentalities, could result in a deterioration in general economic conditions, increased credit losses in the Company’s insured portfolio, impairments or losses in its investment portfolio, and other risks to the Company and its credit ratings that the Company is not able to predict.

In the U.S., debt ceiling and budget deficit concerns, which have increased the possibility of a U.S. government shutdown, payment defaults on the debt of the U.S. government or instruments issued, insured or guaranteed by related institutions, agencies or instrumentalities, and downgrades to their credit ratings, could weaken the global economy and banking system, cause market volatility, raise the cost of credit, reduce public investment, increase interest rates and inflation, negatively impact the Company’s insured and investment portfolios, and disrupt general economic conditions in ways that the Company is not able to predict, which could materially and adversely affect the Company’s business, financial condition and results of operations. While rating agencies currently permit sub-sovereign and corporate credits in the U.S. to be rated higher than sovereign credits, in the event that the U.S. government is downgraded and if the rating agencies no longer permit sub-sovereign and/or corporate credit ratings to be higher than the U.S. government, the resulting downgrades could result in a material adverse impact to the Company’s credit ratings and its insurance and investment portfolios.

The Company may be exposed to a higher risk of default of U.S. public finance obligations in connection with a U.S. government default. While the Company historically has experienced low levels of defaults in its U.S. public finance insured portfolio, from time-to-time state and local governments that issue some of the obligations the Company insures have reported budget shortfalls that have required them to raise taxes and/or cut spending in order to satisfy their obligations. Historically the U.S. federal government has provided aid to state and local governments; however, certain state and local governments remain under financial stress. If the issuers of the obligations in the Company’s U.S. public finance financial guaranty insurance portfolio are reliant on financial assistance from the U.S. government in order to meet their obligations, and the U.S. government does not provide such assistance, the Company may experience credit losses or impairments on those obligations.

A higher U.S. debt-to-GDP ratio and/or downgrade of the U.S. government may also result in higher interest rates, which could adversely affect the distressed RMBS that are in the Company’s insured portfolio, reduce the market value of the fixed-maturity securities held in the Company’s investment portfolio and dampen municipal bond issuance.

Changes in attitudes toward debt repayment could negatively impact the Company’s insurance portfolio.

The likelihood of debt repayment is impacted by both the ability and the willingness of the obligor to repay its debt. Debtors generally understand that debt repayment is not only a legal obligation but is also appropriate, and that a failure to repay their debt will impede their access to debt in the future. To the extent societal attitudes toward the repayment of debt by struggling obligors softens and such obligors believe there to be less of a penalty for nonpayment due to legal rulings or debt relief programs that may absolve them of the repayment obligation or otherwise, some struggling debtors may be more likely to default and, if they default, less likely to agree to repayment plans they view as burdensome. If the issuers of the obligations in the Company’s public finance insurance portfolio become unwilling to raise taxes, decrease spending or receive federal assistance in order to repay their debt, the Company may experience increased levels of losses on its public finance obligations, which could adversely affect its financial condition, results of operations, capital, liquidity, business prospects and share price.

Narrow credit spreads could adversely affect demand for financial guaranty insurance and annuity reinsurance.

Demand for financial guaranty insurance generally fluctuates with changes in market credit spreads. Credit spreads, which are based on the difference between interest rates on high-quality or “risk free” securities versus those on lower-rated securities, fluctuate due to a number of factors, and are sensitive to the absolute level of interest rates, current credit experience and investors’ risk appetite. When the bond market is less volatile or is relatively less risk averse, the credit spread between high-quality or insured obligations versus lower-rated obligations typically narrows. As a result, financial guaranty insurance typically provides lower interest cost savings to issuers than it would during periods of relatively wider credit spreads. Issuers are less likely to use financial guaranties on their new issues when credit spreads are narrow, so (absent other factors) this results in decreased demand or premiums obtainable for financial guaranty insurance. Similarly, demand for annuity insurance and reinsurance products can be a function of the size of credit spreads, with wider credit spreads generally providing purchasers of annuity financial products more opportunities for higher returns.

Credit losses and changes in interest rates could adversely affect the Company’s investments.

The Company’s results of operations are affected by the performance of its investments, which primarily consist of fixed-maturity securities and short-term investments. Credit losses on the Company’s investments adversely affect the Company’s financial condition and results of operations by reducing net income and shareholders’ equity. Alternative investments, including the Company’s equity method investment in Sound Point funds and its ownership interest in Sound Point, Loss Mitigation Securities and CVIs may be more susceptible to credit losses than most of the rest of the Company’s fixed-maturity portfolio.

The impact of changes in interest rates may also adversely affect both the Company’s financial condition and results of operations. For example, if interest rates decline, the value of the Company’s existing fixed-rate investments would generally be expected to increase, resulting in an unrealized gain on investments and improving the Company’s financial condition. At the same time, funds reinvested in new fixed rate investments will have a lower expected yield, reducing the Company’s future investment income compared to the amount it would have earned if interest rates had not declined. Conversely, if interest rates increase, the Company’s future results of operations could improve because of higher future reinvestment income from its new fixed rate investments, but its financial condition could be adversely affected because the value of the fixed-rate investments generally would be reduced. Regarding the Company’s existing floating rate investments, as interest rates decline or increase, income from such investments will generally decrease or increase, respectively, while the value of such investments may or may not experience a material gain or loss commensurate with changes in prevailing interest rates.

Interest rates are highly sensitive to many factors, including monetary policies, U.S. and non-U.S. economic and political conditions and other factors beyond the Company’s control. The Company does not engage in active management, or hedging, of interest rate risk in its investment portfolio, and may not be able to mitigate interest rate sensitivity effectively.

Global climate change may adversely impact the Company’s insurance portfolio and investments.

Global climate change and climate change regulations may impact asset prices and general economic conditions and may disproportionately impact particular sectors, industries or locations. Due to the significant uncertainty of forecasted data related to the impact of climate change, the Company cannot predict the long-term consequences to the Company resulting from the physical, transition, legal, regulatory and reputational risks associated with climate change. The Company considers environmental risk in its insurance underwriting and surveillance process and its investment process and manages its insurance and investment risks by maintaining a well-diversified portfolio of insurance and investments both geographically and by sector and monitors these measures continuously. While the Company can adjust its investment exposure to sectors and/or geographical areas that face severe risks due to climate change or climate change regulation, the Company has less flexibility in adjusting the existing exposure in its insurance portfolio because the majority of the financial guaranties issued by the Company’s insurance subsidiaries insure the credit performance of the guaranteed obligations over an extended period of time, in some cases over 30 years, and, in most circumstances, the Company has no right to cancel such insurance.

Risks Related to Estimates, Assumptions and Valuations

Estimates of expected financial guaranty insurance losses to be paid (recovered), including losses with respect to related legal proceedings, are subject to uncertainties and actual amounts may be different, causing the Company to reserve either too little or too much for future losses.

The financial guaranties issued by the Company’s insurance subsidiaries insure the credit performance of the guaranteed obligations over an extended period of time, in some cases over 30 years, and, in most circumstances, the Company

has no right to cancel such financial guaranties. As a result, the Company’s estimate of ultimate losses to be paid (recovered) on a policy is subject to significant uncertainty over the life of the insured transaction. Additionally, even after the Company pays a claim on its financial guaranties (or determines no claim is owing), subsequent related litigation may result in additional losses. If the Company’s actual losses exceed its current estimate, the Company’s financial condition, results of operations, capital, liquidity, business prospects, financial strength ratings, ability to raise additional capital and share price may all be adversely affected.

The Company does not use traditional actuarial approaches for its financial guaranties to determine its estimates of expected losses to be paid (recovered). The determination of financial guaranty expected loss to be paid (recovered) is an inherently subjective process involving numerous estimates, probability weightings, assumptions and judgments by management, using both internal and external data sources with regard to frequency, severity of loss, economic projections, future interest rates, the perceived strength of legal protections, the perceived strength of the Company’s position in any ongoing legal proceedings, governmental actions, negotiations, delinquency and prepayment rates (with respect to RMBS), timing of cash flows and other factors that affect credit performance. Actual losses will ultimately depend on future events, legal rulings, and/or transaction performance and may be influenced by many interrelated factors that are difficult to predict. As a result, the Company’s current estimates of financial guaranty losses to be paid (recovered), including losses with respect to related legal proceedings, may be subject to considerable volatility and may not reflect the Company’s future ultimate losses paid (recovered).

The Company’s financial guaranty expected loss models and reserve assumptions take into account current and expected future trends, which contemplate the impact of current and possible developments in the performance of the exposure and any related legal proceedings. These factors, which are integral elements of the Company's reserve estimation methodology, are updated on a quarterly basis based on current information. Also, in some instances, the Company may not be able to reasonably estimate the amount or range of loss that could result from an unfavorable outcome of a legal proceeding based on the information available at the stage of the legal proceeding or its estimate may prove to be materially different than the actual results. Financial guaranty loss models and reserve assumptions may be impacted by changes to interest rates due both to discounting and transaction structures that include floating rates, which could impact the calculation of expected losses. Because such information changes over time, sometimes materially, the Company’s projection of financial guaranty losses and its related reserves may also change materially.

See Part II, Item 8. Financial Statements and Supplementary Data, Note 4. Expected Loss to be Paid (Recovered), and Note 17. Contingencies, for additional information.

The valuation of many of the Company’s assets and liabilities includes methodologies, estimates and assumptions that are subjective and could result in changes to valuations of the Company’s assets and liabilities that may materially adversely affect the Company’s financial condition, results of operations, capital, business prospects and share price.

The Company carries a significant portion of its assets and certain of its liabilities at fair value. The approaches used by the Company to calculate the fair value of those assets and liabilities it carries at fair value are described under Part II, Item 8. Financial Statements and Supplementary Data, Note 9. Fair Value Measurement. The determination of fair values is made at a specific point in time, based on available market information and judgments about the assets and liabilities being valued, including estimates of timing and amounts of cash flows and the creditworthiness of the issuer or counterparty. The use of different methodologies and assumptions may have a material effect on estimated fair value amounts.

During periods of market disruption, including periods of rapidly changing credit spreads or illiquidity, it may be difficult to value certain of the Company’s assets and liabilities, particularly if trading becomes less frequent or market data becomes less observable. An increase in the amount of the Company’s alternative investments in its investment portfolio may increase the amount of the Company’s assets subject to this risk. During such periods, more assets and liabilities may fall to the Level 3 valuation level, which describes model derived valuations in which one or more significant inputs or significant value drivers are unobservable, thereby resulting in values that may not be indicative of net realizable value or reflective of future fair values. Rapidly changing credit and equity market conditions could materially impact the valuation of assets and liabilities reported within the financial statements, and period-to-period changes in value could vary significantly.

The Company makes assumptions when pricing its life and annuity reinsurance products relating to longevity, mortality, policy lapses, withdrawals, surrenders, investment returns and expenses, and significant deviations in experience could negatively affect the Company’s financial condition and results of operations.

The Company’s life and annuity reinsurance contracts expose it to longevity risk, which is the risk that the period the Company pays annuity or pension benefits exceeds that which it assumed in pricing its reinsurance contracts. Some of the

Company’s life and annuity reinsurance contracts are exposed to mortality risk, which is the risk that the level of death claims may differ from that which was assumed in pricing the reinsurance contracts. In addition, the Company’s reinsurance contracts are exposed to lapse risk (i.e., risk that a policyholder stops paying premium and allows a policy to terminate before maturity) and withdrawal and/or surrender risk (i.e., where a policyholder withdraws part or all of the cash value of a life insurance policy). An adverse deviation of longevity, mortality, lapse and/or surrender rates from the Company’s expectations could have a negative impact on its financial performance.

The Company’s life and annuity reinsurance risk analysis and underwriting processes are designed with the objective of controlling the quality of this business and establishing appropriate pricing for the risks it assumes. Among other things, these processes rely heavily on the Company’s underwriting, its analysis of longevity and mortality trends, lapse rates, withdrawal and surrender rates, expenses and the Company’s understanding of medical advances or impairments and their effect on longevity or mortality.

The Company expects longevity, mortality, lapse, withdrawal and surrender experience to fluctuate somewhat from period to period, but believes they should remain reasonably predictable over a period of many years. Longevity, mortality, lapse, withdrawal or surrender experience that is less favorable than the rates that the Company used in pricing a reinsurance agreement may cause its net income to be less than otherwise expected because the premiums it receives for the risks it assumes may not be sufficient to cover the claims and profit margin.

The Company regularly reviews its reserves and associated assumptions as part of its ongoing assessment of its business performance. If the Company concludes that its reserves are insufficient to cover actual or expected reinsurance contract liabilities as a result of changes in experience, assumptions or otherwise, the Company would be required to increase its reserves and incur charges in the period in which it makes the determination. The amounts of such increases may be significant, and this could materially adversely affect the Company’s financial condition and results of operations and may require it to fund additional capital in its life and annuity reinsurance business.

The Company’s financial condition and results of operations may also be adversely affected if its actual investment returns and expenses differ from its pricing and reserve assumptions. Changes in economic conditions may lead to changes in market interest rates, credit spreads, availability of liquidity, foreign exchange rates, or changes in the Company’s investment strategies, any of which could cause the Company’s actual investment returns and expenses to differ from its pricing and reserve assumptions.

Strategic Risks

Competition in the Company’s industries may adversely affect its financial condition, results of operations, capital, business prospects and share price.

As described in greater detail under Item 1. Business — Insurance — Market Demand and Competition and Item 1. Business — Asset Management — Market Demand and Competition, the Company can face competition in its financial guaranty insurance, life and annuity reinsurance and asset management businesses from other insurance companies, providers of other credit enhancement, or other asset managers which could have an adverse effect on the Company’s financial condition, results of operations, capital, business prospects and share price.

The life and annuity reinsurance market is extremely competitive and expansion of the Company’s life and annuity reinsurance business may be slower than anticipated. While the Company believes that its annuity reinsurance platform provides a compelling market proposition, it may experience difficulties executing its business strategies, including market acceptance of the Assured Life Re platform and obtaining acceptable market rates of return for business opportunities.

The Company’s Asset Management segment primarily consists of its ownership interest in Sound Point, which operates in highly competitive markets. Sound Point competes with many other firms in every aspect of the asset management industry, including raising funds, seeking investments, and hiring and retaining professionals. Sound Point’s ability to increase and retain AUM is directly related to the performance of the assets it manages as measured against market averages and the performance of its competitors. Some of Sound Point’s competitors may have a lower cost of funds and access to funding and other resources that are not available to Sound Point. In addition, some of Sound Point’s competitors may have higher risk tolerances or different risk assessments, which could allow them to consider a wider variety of investments and establish more relationships than Sound Point does. Furthermore, Sound Point may lose investment opportunities if it does not match its competitors’ pricing, terms and structure. The loss of such investment opportunities may limit Sound Point’s ability to grow or cause it to have to shrink the size of its AUM, which could decrease its earnings. If Sound Point matches its competitors’ pricing, terms and structure, it may experience decreased earnings and increased risk of investment losses. If Sound Point is

unable to successfully compete, it may result in decreased earnings for Sound Point and increased risk of investment losses in Sound Point funds, which could materially adversely impact the Company’s ownership interest in Sound Point and/or its investment in Sound Point funds and, ultimately, the Company’s financial condition, results of operations, capital, business prospects and share price.

Strategic transactions may not result in the benefits anticipated.

From time to time the Company evaluates potential mergers, acquisitions, divestitures and other strategic opportunities, including transactions involving legacy financial guaranty companies and financial guaranty portfolios, asset managers, life and annuity reinsurers, and other companies, and has executed a number of such transactions in the past. Such transactions may involve some or all of the various risks commonly associated with such strategic transactions, including, among other things: (a) failure to adequately identify and value potential exposures and liabilities associated with a new entity or portfolio; (b) difficulty in estimating the value of a new entity or portfolio; (c) potential diversion of management’s time and attention; (d) exposure to asset quality issues of a new entity or portfolio; (e) difficulty and expense of integrating the operations, systems and personnel of a new entity; (f) difficulty integrating the culture of a new entity; (g) failure to identify legal risks associated with the strategic transaction with an entity or portfolio, (h) failure of a strategic transaction to perform as expected, (i) deployment of financial resources towards certain strategic initiatives may limit the Company’s ability to deploy capital for other strategic initiatives or other purposes, and (j) in the case of acquisitions of a financial guaranty company or portfolio, concentration of insurance exposures, including insurance exposures which may exceed single risk limits, aggregate risk limits, BIG limits and/or non-U.S. dollar exposure limits, due to the addition of the target insurance portfolio. Such strategic transactions related to entities or portfolios may also have unintended consequences on ratings assigned by the rating agencies to the Company or its insurance subsidiaries or on the applicability of laws and regulations to the Company’s existing businesses. These or other factors may cause any past or future strategic transactions relating to financial services entities or portfolios not to result in the benefits to the Company that the Company anticipated when the transaction was agreed. Past or future transactions may also subject the Company to non-monetary consequences that may or may not have been anticipated or fully mitigated at the time of the transaction.

Additionally, if the Company enters into discussions regarding a strategic transaction and a transaction is not consummated, especially if such discussions become known, related portions of the Company’s business may be negatively impacted.

The Company’s investments in Sound Point are subject to the risks of Sound Point’s business that may adversely affect the Company’s financial condition, results of operations, capital, business prospects and share price.

Since July 1, 2023, the Company participates in the asset management business through its ownership interest in Sound Point, which is subject to the risks of Sound Point’s business. See Item 1. Business — Asset Management. External factors, such as changes in inflation, interest rates, credit markets or segments thereof, geopolitical risk, developments in the global financial markets, general macroeconomic factors, and industry conditions, as well as the financial performance of Sound Point relative to the Company’s expectations at the time of the Sound Point Transaction, could result in an impairment, which could adversely affect the Company’s financial condition, results of operations and share price.

Asset management services are primarily a fee-based business, and Sound Point’s asset management and performance fees are based on the amount of its AUM as well as the performance of those assets. Sound Point’s business operates in highly competitive markets with many other firms in every aspect of the asset management industry. See “– Competition in the Company’s industries may adversely affect its financial condition, results of operations, capital, business prospects and share price.” Industry competition, volatility or declines in the markets in which Sound Point invests as an asset manager, or poor performance of its investments, may negatively affect its AUM and its asset management and performance fees, may deter future investment by third parties in Sound Point’s asset management products, and may result in an impairment to the Company’s ownership interest in Sound Point.

Sound Point is dependent on certain key personnel, including Sound Point’s Managing Partner and Chief Investment Officer, and its future success depends on their continued service. The departure of any of Sound Point’s key personnel for any reason could have a material adverse effect on Sound Point’s business, financial condition or results of operations and, consequently, the Company’s ownership interest in Sound Point and/or its investments in Sound Point funds, other vehicles and separately managed accounts.

The asset management business is also subject to legal, regulatory, compliance, accounting, valuation and political risks that differ from those that may affect the Company’s insurance business. Sound Point operates in a highly regulated industry and, as a registered investment adviser, is subject to the provisions of the Investment Advisers Act of 1940, as

amended. Sound Point is, from time to time, subject to formal and informal examinations, investigations, inquiries, audits and reviews from numerous regulatory authorities both in response to issues and questions raised in such examinations or investigations and in connection with the changing priorities of the applicable regulatory authorities across the market in general.

Because the Company does not control the business, management or policies of Sound Point, it relies upon Sound Point to make appropriate decisions and operate in a manner consistent with applicable rules and regulations. In turn, Sound Point may rely on third party service providers such as custodians and fund administrators whom they do not control to comply with applicable rules and regulations. Failure of Sound Point or its service providers to comply with applicable rules and regulations could have a material adverse effect on the value of the Company’s ownership interest in Sound Point and/or its investments in Sound Point funds, other vehicles and separately managed accounts.

The Company’s interest in Sound Point is subject to the risks normally associated with a noncontrolling interest.

Since the Company holds a noncontrolling interest in Sound Point, it is unable to control the business, management or policies of Sound Point. For example, the Company is not be able to control the timing or amount of distributions from Sound Point and is not involved on a day-to-day basis with Sound Point’s operations or its decision-making or its adoption and implementation of policies and procedures with respect to its investment, reporting, internal control, legal, compliance or risk functions. In most cases, the Company will be bound by the decisions made by the Managing Partner and Chief Investment Officer, other members of management and the Board of Managers of Sound Point. In the event that the Managing Partner and Chief Investment Officer, other members of management and the Board of Managers of Sound Point have interests, objectives and incentives that differ from those of the Company, there can be no assurance that the decisions they make will be aligned with the interests of the Company. Decisions made by the Managing Partner and Chief Investment Officer, other members of management and the Board of Managers of Sound Point not in the Company’s interest could have a material adverse effect on the Company’s interest in Sound Point and/or its investments in Sound Point funds, other vehicles and separately managed accounts.

Alternative investments, including allocations of investments to Sound Point and the exclusivity arrangement with Sound Point, may not result in the benefits anticipated, and may expose it to increased credit, interest rate, liquidity, reputational and other risks.

The Company has invested in alternative investments, and may over time increase the proportion of the Company’s assets invested in alternative investments. Alternative investments may be riskier than other investments the Company makes, and may not result in the benefits anticipated at the time of the investment. Alternative investments are generally less liquid than most of the Company’s other investments and so may be difficult to convert to cash or investments that receive more favorable treatment under the capital models to which the Company is subject, and so may increase the risks described under “— Operational Risks — The ability of AGL and its subsidiaries to meet their liquidity needs may be limited.” Although the Company uses what it believes to be excess capital to make alternative investments, measures of required capital can fluctuate and such assets may not be given much, or any, value under the various rating agency, regulatory and internal capital models to which the Company is or may be subject. In addition, the changes in fair value of certain of these assets are reported in results of operations may be more volatile than net investment income earned from fixed maturity securities.

The Company is using Sound Point’s investment knowledge and experience to expand the categories and types of its alternative investments by: (a) allocating capital in Sound Point managed funds, other vehicles and separately managed accounts; (b) redeploying return of capital, gains and dividends from Sound Point managed funds, other vehicles and separately managed accounts in future Sound Point managed funds, other vehicles and separately managed accounts; and (c) having Sound Point serve as AG’s sole alternative credit manager. This expansion of categories and types of investments, allocations to Sound Point and exclusivity arrangement with Sound Point may increase the credit, interest rate and liquidity risk in the Company’s investments and expose the Company to reputational or other risks.

A downgrade of the financial strength or financial enhancement ratings of any of the Company’s insurance or reinsurance subsidiaries may adversely affect its business prospects.

The financial strength and financial enhancement ratings assigned by S&P, Moody’s, KBRA, A.M. Best Company, Inc. and Fitch Ratings, Inc. to the Company’s insurance and reinsurance subsidiaries represent such rating agencies’ opinions of the insurer’s financial strength and ability to meet ongoing obligations to policyholders and cedants in accordance with the terms of the financial guaranties it has issued or the reinsurance agreements it has executed. Issuers, investors, underwriters, ceding companies and others consider the Company’s financial strength or financial enhancement ratings an important factor when deciding whether or not to utilize a financial guaranty or purchase reinsurance from one of the Company’s insurance or

reinsurance subsidiaries. The ratings assigned by the rating agencies to the Company’s insurance subsidiaries are subject to review and may be lowered by a rating agency at any time and without notice to the Company. In the event of a downgrade by a rating agency of the financial strength or financial enhancement ratings of one or more of the Company’s subsidiaries, certain beneficiaries may have the right to cancel their credit protection and certain ceding companies may have a right to cancel policies ceded to the Company’s insurance subsidiaries and recapture premium, in each case resulting in the loss of future premium earnings and the reversal of any fair value gains recorded by the Company. See Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity — Insurance Subsidiaries —Assumed Reinsurance. In addition, any such downgrade may result in the loss of future premium if potential policyholders would receive less benefit from a financial guaranty issued by a lower rated insurance company. Any such downgrade, resulting loss of premium earnings and reversal of fair value gains may impair the Company’s financial condition, results of operation, capital, liquidity, business prospects and/or share price.

The rating agencies have changed their methodologies and criteria from time to time. Factors influencing the rating agencies are beyond management's control and not always known to the Company. In the event of an actual or perceived deterioration in creditworthiness of large risks in the Company’s insurance portfolio, or other large increases in liabilities (including those related to legal proceedings), or a change in a rating agency’s capital model or rating methodology, a rating agency may require the Company to increase the amount of capital it holds to maintain its financial strength and financial enhancement ratings under the rating agencies’ capital adequacy models, or a rating agency may identify an issue that additional capital would not address. The amount of any capital required may be substantial, and may not be available to the Company on favorable terms and conditions or at all, especially if it were known that additional capital was necessary to preserve the Company’s financial strength or financial enhancement ratings. The failure to raise any additional required capital, or successfully address another issue or issues raised by a rating agency, could result in a downgrade of the ratings of the Company’s insurance subsidiaries and thus have an adverse impact on its business, results of operations, financial condition and share price.

The Company periodically assesses the value of each rating assigned to each of its companies and may, as a result of such assessment, request that a rating agency add or drop a rating from certain of its subsidiaries. For example, a Moody’s rating was dropped from AG Re and AGRO in 2015.

The insurance subsidiaries’ financial strength and financial enhancement ratings are an important competitive factor in the financial guaranty insurance and reinsurance markets. If the financial strength or financial enhancement ratings of one or more of the Company’s insurance subsidiaries were reduced below current levels, the Company expects that the number of transactions that would benefit from the Company’s insurance would be reduced and that its premium rates on new business would decrease; consequently, a downgrade by rating agencies could harm the Company’s new insurance business production.

The Assured Life Re Acquisition may negatively impact the Company, including how it is perceived by its investors, regulators, rating agencies or obligors it insures, as well as Assured Life Re’s business relationships.

The Assured Life Re Acquisition represents the Company’s platform dedicated solely to the life and annuity reinsurance business and may involve significant investments by the Company. The Company has engaged in preliminary discussions regarding the Assured Life Re Acquisition with its relevant regulators and with the rating agencies, and, on that basis, does not believe that the Assured Life Re Acquisition will have a negative impact on its regulators’ or rating agencies’ views of Assured Guaranty or cause those regulators or rating agencies to take any actions that would impede the Company's continued pursuit of its current businesses. There can be no assurance, however, that the Assured Life Re Acquisition will not negatively impact the Company or the perception of the Company by its investors, regulators, rating agencies or obligors it insures and/or its business or results of operations.

The Company and Assured Life Re are dependent on the experience and industry knowledge of their respective management personnel and other key employees, including, in the case of Assured Life Re, key life and annuity reinsurance professionals, to execute their business plans. The Company’s success in the life and annuity reinsurance business will depend in part upon the ability of the Company and Assured Life Re to attract, motivate and retain key management personnel and other key employees, including asset-liability management financial professionals and other key life and annuity reinsurance professionals. Uncertainties associated with the Assured Life Re Acquisition may result in the departure of management personnel and other key employees at Assured Life Re or the Company, and Assured Life Re and the Company may have difficulty attracting and motivating management personnel and other key employees

Entering the life and annuity reinsurance business may present integration risks and other risks specific to the life and annuity reinsurance business that could have a negative effect on the Company’s business, results of operations or financial condition.

While the Assured Life Re Acquisition is intended to diversify Assured Guaranty’s earnings, entering this business line, which the Company believes is in line with its risk profile and benefits from its core competencies, may present integration risks as well as new risks that could have a negative effect on the Company's business, results of operations or financial condition.

The Company’s focus on the growth of the life and annuity reinsurance business may divert management’s attention from the Company’s core operations and other priorities resulting in strategic misalignment. Moreover, the use of the Company’s financial resources for the Assured Life Re Acquisition and growth of the life and annuity reinsurance business may limit the Company’s ability to invest in other strategic initiatives or deploy capital for other purposes.

Successfully integrating Assured Life Re into the Company’s existing operations involves challenges such as integrating or implementing new complex systems, preparing Assured Life Re’s financial statements in accordance with GAAP and in compliance with the SEC’s accounting regulations, consolidating financial statements, aligning organizational cultures, and retaining key personnel. Failure to effectively manage any of the integration processes could disrupt the Company’s operations and negatively impact its financial performance.

The Company’s due diligence process may not have identified all potential liabilities and risks associated with the Assured Life Re Acquisition. This could result in unexpected financial and operational challenges post-acquisition, including regulatory non-compliance, undisclosed liabilities, or operational inefficiencies.

Assured Life Re’s life and annuity reinsurance business is also subject to legal, regulatory and compliance risks that differ from those involved in the Company’s current business of providing credit protection products. Failure to comply with applicable laws or regulations can result in legal penalties, regulatory actions, or reputational damage, which could have a material adverse effect on the Company’s business. In addition, in recent years, annuity and reinsurance products have come under increased regulatory scrutiny reflecting concerns over financial stability, consumer protection, and the evolving complexity of insurance-linked financial products, potentially leading to increased compliance costs, limitations on forms of product offerings, and higher capital and solvency requirements, which could negatively impact the business and financial performance of Assured Life Re.

Operational Risks

Fluctuations in foreign exchange rates may adversely affect the Company’s financial position and results of operations.

The Company’s reporting currency is the U.S. dollar. The functional currency of the Company’s insurance and reinsurance subsidiaries is the U.S. dollar. The Company’s subsidiaries maintain both assets and liabilities in currencies different from their functional currencies, which exposes the Company to changes in currency exchange rates. The investment portfolios of non-U.S. subsidiaries are primarily invested in local currencies in order to satisfy regulatory requirements and to support local insurance operations regardless of currency fluctuations.

The principal currencies creating foreign exchange risk to the Company are the pound sterling and the euro. The Company cannot accurately predict the nature or extent of future exchange rate variability between these currencies or relative to the U.S. dollar. Foreign exchange rates are sensitive to factors beyond the Company’s control.

The Company does not engage in active management, or hedging, of foreign exchange rate risk in its financial guaranty business. Therefore, fluctuation in exchange rates between the U.S. dollar and the pound sterling or the euro could adversely impact the Company’s financial position, results of operations and cash flows. See Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk — Sensitivity to Foreign Exchange Rate Risk.

The Company’s underwriting of insurance in non-U.S. markets and/or covering new sectors or classes of business may expose it to less predictable political, credit and legal risks.

The Company pursues new business opportunities in non-U.S. markets and/or covering new sectors or classes of business. The underwriting of obligations of an issuer in a country other than the U.S. involves the same process as that for a U.S. issuer, but additional risks must be addressed, such as the evaluation of currency exchange rates, non-U.S. business and legal issues, and the economic and political environment of the country or countries in which an issuer does business. Changes in such factors could impede the Company’s ability to insure, or increase the risk of loss from insuring, obligations in the non-U.S. countries in which it currently does business and limit its ability to pursue business opportunities in other non-U.S. countries.

The underwriting of insurance in new sectors or classes of business may subject the Company to additional credit risk because its underwriting history and loss experience for such exposures is minimal or nonexistent which could adversely affect the Company’s results of operations. In addition, the underwriting of insurance in new sectors or classes of business may present novel legal issues or political challenges beyond the Company’s control.

The Company is dependent on members of senior management and other key employees and the loss of any of these individuals, or the delay or inability to develop or recruit suitable replacements, could adversely affect its business.

The Company’s success substantially depends upon its ability to attract, motivate and retain qualified employees and upon the ability of its senior management and other key employees to implement its business strategy. The Company believes there are only a limited number of available qualified executives in the insurance business lines in which the Company competes.

The Company relies substantially upon the services of its Chief Executive Officer, other members of senior management and other key employees. The market to build, retain and replace talent is highly competitive. Although the Company has succession plans and has designed its compensation plans with the goal of retaining and creating incentives for its senior management and other key employees, the Company’s succession plans may not operate effectively and the Company may not be successful in retaining the services of senior management and other key employees. The loss of the services of any of these individuals, or the delay or inability to develop or recruit suitable replacements, could adversely affect the implementation of its business strategy.

The Company is dependent on its information technology and that of certain third parties, and a cyberattack, security breach or failure in the Company’s or a third party provider’s information technology system, or a data privacy breach of the Company’s or a vendor’s information technology system, could adversely affect the Company’s business.

The Company relies upon information technology and systems, including technology and systems provided by or interfacing with those of third parties, to conduct its businesses and interact with market participants and vendors. The Company’s ability to adequately price products and services, to establish reserves, to provide effective, efficient and secure service to its customers, to value its investments and to timely and accurately report its financial results also depends significantly on the integrity and availability of the data it maintains, including that within its information systems, as well as data in, and assets held through, third party service providers and systems. A cybersecurity threat or breach of the Company’s systems or the systems of its third party providers in the future could have a material adverse effect on the Company, including its business strategy, results of operations or financial condition. The Company receives and stores confidential information, including personally identifiable information, in connection with certain loss mitigation and due diligence activities related to its businesses, along with information regarding employees and directors and counterparties, among others. A breach of these systems could jeopardize the personal information of the Company’s employees, consultants and vendors, or sensitive and confidential information regarding the Company’s business and other information processed and stored within these systems, which could result in operational impairments, business interruptions, lost business, reputational harm, the disclosure or misuse of confidential, proprietary or personal information, incorrect reporting, legal costs, regulatory penalties (including under applicable data protection laws and regulations) and financial losses that may not be insured against or not fully covered by insurance, all of which would have an adverse effect on the Company’s business.

Information technology security threats and events are increasing in frequency and sophistication. The rapid evolution and increased adoption of computer systems that are able to learn and adapt without following explicit instructions or perform tasks that simulate human intelligence (Artificial Intelligence) technologies may intensify the Company’s cybersecurity risks. As Artificial Intelligence capabilities improve and are increasingly adopted, they may be used by bad actors to identify vulnerabilities and craft increasingly sophisticated cybersecurity attacks. In addition, vulnerabilities may be introduced from the use of Artificial Intelligence by the Company, its counterparties, vendors and other business partners and third party providers. Although the Company has implemented administrative and technical controls and has taken protective actions designed to reduce the risk of cyber incidents and to protect its information technology and assets, the Company’s data systems and those of third parties on which it relies have been, and the Company expects will continue to be, vulnerable to and the target of, security and data privacy breaches due to cyberattacks, viruses, malware, ransomware, other malicious codes, hackers, unauthorized access, or other computer-related penetrations, and other external hazards, as well as inadvertent errors, equipment and system failures, and employee misconduct. Over time, the frequency and sophistication of such threats continue to increase and often become further heightened in connection with geopolitical tensions, including hostile actions taken by nation-states or terrorist organizations. As a result, the Company may be required to expend significant additional resources to modify its protective measures or to investigate and remediate vulnerabilities or other exposures and to pursue recovery of lost data or assets. In addition, like other global companies, the Company has an increasing challenge of attracting and retaining highly qualified personnel to assist in combating these security threats.

The Company’s business operations rely on the continuous availability of its computer systems as well as those of certain third parties. In addition to disruptions caused by cyberattacks or data privacy breaches, such systems may be adversely affected by natural and man-made catastrophes. The Company’s failure to maintain business continuity in the wake of such events, particularly if there were an interruption for an extended period, could prevent the timely completion of critical processes across its operations, including, for example, financial reporting, claims processing, regulatory filings, treasury and investment operations and payroll. These failures could result in additional costs, loss of business, fines and litigation.

Evolving cybersecurity, privacy and data security regulations could adversely affect the Company’s business.

The Company and its subsidiaries are subject to numerous cybersecurity, data privacy and protection laws and regulations in a number of jurisdictions, particularly with regard to personally identifiable information, including the EU General Data Protection Regulation, the UK Data Protection Act 2018, and the Bermuda Personal Information Protection Act 2016. In the U.S., there are numerous federal, state and local cybersecurity, privacy and data security laws and regulations governing the collection, sharing, use, retention, disclosure, security, transfer, storage and other processing of personal information. These laws and regulations are increasing in complexity and number, change frequently, and sometimes conflict. The Company’s compliance efforts are further complicated by the fact that these cybersecurity, privacy and data security laws and regulations around the world may be subject to uncertain or inconsistent interpretations and enforcement. The Company’s failure to comply with these requirements could result in penalties and fines, regulatory enforcement actions, reputational harm and/or criminal prosecution in one or more jurisdictions, which could require significant effort from its management and technical personnel to remedy, increase the Company’s costs of doing business, and ultimately have a material adverse effect on the Company’s business, financial condition and results of operations.

The Company continues to explore the use of Artificial Intelligence in some of its business operations, and challenges with properly managing the use of Artificial Intelligence, compliance with new laws and regulations applicable to Artificial Intelligence, difficulties implementing Artificial Intelligence technologies efficiently and effectively, and challenges to the Company’s competitive position from faster or more effective use of Artificial Intelligence by competitors or other third-parties, could adversely affect the Company’s business.

The Company continues to explore the use of Artificial Intelligence technologies in its business, and its research into and continued deployment of such capabilities remain ongoing. The introduction and use of Artificial Intelligence technologies may result in unintended consequences or other new or expanded risks and liabilities. If the content, analyses or recommendations that Artificial Intelligence applications assist in producing are, or are alleged to be, deficient, inaccurate or biased, such as due to limitations in Artificial Intelligence algorithms, insufficient or biased base data or flawed training methodologies, the Company’s business, financial condition, results of operations and reputation may be adversely affected. In addition, the use of Artificial Intelligence carries inherent risks related to data privacy and security, such as unintended or inadvertent transmission of proprietary or sensitive information, including personal data. There is uncertainty in the legal and regulatory landscape for Artificial Intelligence, which is not fully developed and rapidly evolving, and any laws, regulations or industry standards adopted in response to the emergence of Artificial Intelligence may be burdensome, could entail significant costs, and may restrict or impede the Company’s ability to successfully develop, adopt and deploy Artificial Intelligence technologies efficiently and effectively. Additionally, the Company’s competitors or other third parties may incorporate Artificial Intelligence into their products and services more quickly or more successfully, which could cause the Company to experience competitive disadvantages that adversely affect its results of operations.

Errors in, overreliance on or misuse of models may result in financial loss, reputational harm or adverse regulatory action.

The Company uses models for numerous purposes in its business. For example, it uses models to project future cash flows associated with pricing models, calculating insurance expected losses to be paid (recovered), evaluating risks in its insurance portfolio and investments, valuing assets and liabilities and projecting liquidity needs. It also uses models to determine and project capital requirements under its own risk model as well as under regulatory and rating agency requirements. While the Company has a model governance and validation function and has adopted procedures to protect its models, the models may not operate properly (including as a result of errors or damage) and may rely on assumptions that are inherently uncertain and may prove to have been incorrect.

Significant claim payments may reduce the Company’s liquidity.

Claim payments and payments made in connection with related legal proceedings reduce the Company’s invested assets and result in reduced liquidity and net investment income, even if the Company is reimbursed in full over time and does not experience ultimate loss on the claim. In the years after the global financial crisis that began in 2008, many of the larger claims paid by the Company were with respect to insured U.S. RMBS securities and, beginning in 2016, certain insured Puerto

Rico exposures. If the amount of future claim payments is significantly more than that projected by the Company, the Company’s ability to make other claim payments and its financial condition, financial strength ratings and business prospects and share price could be adversely affected.

The Company may face a sudden need to raise additional capital as a result of insurance losses substantially in excess of the stress scenarios for which it plans, or as a result of changes in regulatory or rating agency capital requirements applicable to its insurance subsidiaries, which additional capital may not be available or may be available only on unfavorable terms.

The Company’s capital requirements depend on many factors, primarily related to its in-force book of insurance business and rating agency capital requirements for its insurance subsidiaries. Failure to raise additional capital if and as needed may result in the Company being unable to write new insurance business and may result in the ratings of the Company and its insurance subsidiaries being downgraded by one or more rating agencies. The Company’s access to external sources of financing, as well as the cost of such financing, is dependent on various factors, including the market supply of such financing, the Company’s long-term debt ratings and insurance financial strength and enhancement ratings and the perceptions of its financial strength and the financial strength of its insurance subsidiaries. The Company’s debt ratings are in turn influenced by numerous factors, such as financial leverage, balance sheet strength, capital structure and earnings trends. If the Company’s need for capital arises because of significant insurance losses substantially in excess of the stress scenarios for which it plans, the occurrence of such losses may make it more difficult for the Company to raise the necessary capital.

Future capital raises from the issuance of equity or equity-linked securities could also result in dilution to the Company’s shareholders. In addition, some securities that the Company could issue, such as preferred stock or securities issued by the Company's operating subsidiaries, may have rights, preferences and privileges that are senior to those of its common shares.

Large insurance losses could increase substantially the Company’s insurance subsidiaries’ leverage ratios, which may prevent them from writing new insurance.

Insurance regulatory authorities impose capital requirements on the Company’s insurance subsidiaries. These capital requirements, which include leverage ratios and surplus requirements, may limit the amount of insurance that the subsidiaries may write. A material reduction in the statutory capital and surplus of an insurance subsidiary, whether resulting from underwriting or investment losses, a change in regulatory capital requirements or another event, or a disproportionate increase in the amount of risk in force, could increase a subsidiary’s leverage ratio. This in turn could require that subsidiary to obtain reinsurance for existing business or add to its capital base (neither of which may be available, or may be available only on terms that the Company considers unfavorable). Failure to maintain regulatory capital levels could limit that insurance subsidiary’s ability to write new business.

The Company’s holding companies’ ability to meet their obligations may be constrained.

Each of AGL, AGUS and AGMH is a holding company and, as such, has no direct operations of its own. None of the holding companies expect to have any significant operations or assets other than its ownership of the stock of its subsidiaries and its equity method ownership interest in Sound Point and certain alternative investments. The Company expects that dividends and other payments from the insurance companies will be the primary source of funds for AGL, AGUS and AGMH to meet ongoing cash requirements, including operating expenses, intercompany loan payments, any future debt service payments and other expenses, to pay dividends to their respective shareholders, to fund any acquisitions, to fund investments and commitments to alternative investments, and, in the case of AGL, to repurchase its common shares. The insurance subsidiaries’ ability to pay dividends and make other payments depends, among other things, upon their financial condition, results of operations, cash requirements and compliance with rating agency requirements, and is also subject to restrictions contained in the insurance laws and related regulations of their respective state/country of domicile. Additionally, in recent years AG and AGUK have sought and been granted permission from their insurance regulators to make discretionary payments to their corporate parents in excess of the amounts permitted by right under the insurance laws and related regulations. There can be no assurance that such regulators will permit discretionary payments in the future. Accordingly, if the insurance subsidiaries are unable to pay sufficient dividends and other permitted payments at the times or in the amounts that are required, that would have an adverse effect on the ability of AGL, AGUS and AGMH to satisfy their ongoing cash requirements and on their ability to pay dividends to shareholders or repurchase common shares or fund other activities, including acquisitions.

The ability of AGL and its subsidiaries to meet their liquidity needs may be limited.

Each of AGL, AGUS and AGMH requires liquidity, either in the form of cash or in the ability to easily sell investments for cash, in order to meet its payment obligations, including, without limitation, its operating expenses, interest and

principal payments on debt and dividends on common shares, to fund investments and commitments to alternative investments, and to make capital investments in operating subsidiaries. Such cash is also used by AGL to repurchase its common shares. The Company’s operating subsidiaries require substantial liquidity to meet their respective payment and/or collateral posting obligations, including under financial guaranty insurance policies or reinsurance agreements. They also require liquidity to pay operating expenses, reinsurance premiums, dividends to AGUS or AGMH for debt service and dividends to AGL, fund investments and commitments to alternative investments, as well as, where appropriate, to make capital investments in their own subsidiaries. In addition, the Company may require substantial liquidity to fund any future strategic initiatives. The Company cannot give any assurance that the liquidity of AGL and its subsidiaries will not be adversely affected by adverse market conditions, changes in insurance regulatory law, insurance claim payments and related litigation substantially in excess of those projected by the Company in its stress scenarios, or changes in general economic conditions.

AGL anticipates that its liquidity needs will be met by the ability of its operating subsidiaries to pay dividends or to make other payments; from earnings from its ownership interest in Sound Point; external financings; investment income from its invested assets; and current cash and short-term investments. The Company expects that its subsidiaries’ need for liquidity will be met by the operating cash flows of such subsidiaries; external financings; investment income from their invested assets; and proceeds derived from the sale of their investments, portions of which are in the form of cash or short-term investments. The value of the Company’s investments may be adversely affected by changes in interest rates, credit risk and capital market conditions that therefore may adversely affect the Company’s potential ability to sell investments quickly and the price which the Company might receive for those investments. Part of the Company’s investment strategy is to invest more of its excess capital in alternative investments, which may be particularly difficult to sell at adequate prices, or at all.

The Company’s sources of liquidity are subject to market, regulatory or other factors that may impact the Company’s liquidity position at any time. As discussed above, AGL’s insurance subsidiaries are subject to regulatory and rating agency restrictions limiting their ability to declare and to pay dividends and make other payments to AGL. As further noted above, external financing may or may not be available to AGL or its subsidiaries in the future on satisfactory terms.

Losses arising from asset/liability mismatch in the Company’s annuity reinsurance business could have an adverse effect on its financial condition, results of operations, and ability to meets its obligations under annuity reinsurance contracts.

The Company’s annuity reinsurance business is subject to the risk of asset/liability mismatch, which arises when the characteristics of the assets held do not align with the expected timing, amount, or nature of the liabilities assumed under reinsurance contracts. This mismatch may occur for several reasons, including due to differences in interest rate sensitivity, liquidity profiles, credit quality, or duration between assets and liabilities. In particular, the liabilities associated with annuity reinsurance contracts often involve complex cash flow patterns, and changes in market conditions can influence policyholder behavior, including in respect of surrenders, transfers, benefit elections, and retirement timing, while the underlying investment portfolio may be subject to market volatility, changing interest rates, and evolving credit conditions.

If the Company’s investment strategy fails to adequately match the cash flows, durations, or risk profiles of its assets and liabilities, it could be exposed to increased volatility in earnings, difficulties in meeting contractual obligations, or the need to liquidate assets under unfavorable market conditions. Additionally, sudden shifts in interest rates or adverse market movements may exacerbate mismatches, potentially requiring the Company to raise additional capital, adjust its investment portfolio and realize losses, or experience reduced profitability. Asset and liability mismatches may also affect collateral arrangements, obliging the Company to fund any shortfalls that arise under such agreements. If the Company is unable to post collateral due to liquidity constraints or other reasons, its annuity reinsurance business may be subject to termination and recapture.

The Company actively manages this risk through prudent asset/liability management practices, including by maintaining a well-diversified investment portfolio with a duration closely aligned to that of its liabilities, holding prudent short-term liquidity buffers, and hedging interest rate, inflation, and currency risks; however, there can be no assurance that such efforts will be successful in all market environments. Failure to effectively manage asset/liability mismatch risk could have an adverse effect on the Company’s financial condition, results of operations, and ability to meet its obligations under annuity reinsurance contracts.

Risks Related to Taxation

Changes in U.S. tax laws could reduce the demand or profitability of financial guaranty insurance, or negatively impact the Company’s investments.

Changes in U.S. federal, state or local laws that materially adversely affect the tax treatment of municipal securities, including potential loss of tax-exemption, may impact the market for those securities and result in lower volume and demand for municipal obligations and also may adversely impact the value and liquidity of the Company’s investments, a significant portion of which is invested in tax-exempt instruments.

Certain of the Company’s non-U.S. subsidiaries may be subject to U.S. tax.

The Company manages its business so that AGL and its non-U.S. subsidiaries (except for its non-U.S. subsidiaries that elect to be taxed as a U.S. corporation) operate in such a manner that none of them should be subject to U.S. federal tax (other than U.S. excise tax on insurance and reinsurance premium income attributable to insuring or reinsuring U.S. risks, and U.S. withholding tax on certain U.S. source investment income). However the Company cannot be certain that the IRS will not contend successfully that AGL or any of its non-U.S. subsidiaries (except for its non-U.S. subsidiaries that elect to be taxed as a U.S. corporation) is/are engaged in a trade or business in the U.S., in which case each such company could be subject to U.S. corporate income and branch profits taxes on the portion of its earnings effectively connected to such U.S. business. See Item 1. Business — Tax Matters — Taxation of AGL and Subsidiaries— United States.

AGL may become, and AG Re and AGRO are, subject to taxes in Bermuda, which may adversely affect the Company’s future results of operations and an investment in the Company.

The Bermuda Minister of Finance, under Bermuda’s Exempted Undertakings Tax Protection Act 1966, as amended, has given AGL, AG Re and AGRO an assurance that if any legislation is enacted in Bermuda that would impose tax computed on profits or income, or computed on any capital asset, gain or appreciation, or any tax in the nature of estate duty or inheritance tax, then subject to certain limitations the imposition of any such tax will not be applicable to AGL, AG Re or AGRO, or any of AGL’s or its subsidiaries’ operations, stocks, debentures or other obligations until March 31, 2035.

Notwithstanding the above, on December 27, 2023 the Government of Bermuda enacted a corporate income tax which applies to accounting periods starting on or after January 1, 2025. Importantly, under the Corporate Income Tax Act 2023 of Bermuda, any liability to the tax will apply regardless of any assurances previously provided under the Exempted Undertakings Tax Protection Act 1966 of Bermuda. Broadly, the Bermuda corporate income tax is intended to be treated as a covered tax for the purposes of Pillar Two (see below) and therefore no double taxation is expected to arise from these rules and the top-up taxes under Pillar Two in other jurisdictions. AG Re and AGRO are subject to this tax beginning in 2025.

Further, the Corporate Income Tax Act 2023 of Bermuda incorporates a number of measures which allow Bermuda resident companies to recognize deferred tax assets in respect of certain ETAs which may be utilized in the calculation of the Company’s effective tax rate for the purposes of top-up taxes in other jurisdictions. The Company believes that the corporate income tax imposed by the Corporate Income Tax Act 2023 of Bermuda would not be applicable to AGL because AGL is a UK tax resident but is applicable to its Bermuda subsidiaries.

However, the treatment of the Bermuda corporate income tax as a covered tax is subject to interpretation in other jurisdictions and therefore remains uncertain at this time. If the Bermuda corporate income tax is not regarded as a covered tax for the purposes of Pillar Two in other jurisdictions, this may have a material impact on the Company’s future income tax expense. In addition, a change in the Corporate Income Tax Act 2023 or its interpretation, or any change in the regulatory treatment of the corporate income tax or matters related thereto, by Bermuda could adversely affect Assured Guaranty’s financial results. See “– Assured Guaranty’s financial results may be affected by measures taken in response to the OECD BEPS project”.

U.S. Persons who hold 10% or more of AGL’s shares directly or through non-U.S. entities may be subject to taxation under the U.S. CFC rules.

If AGL and/or a non-U.S. subsidiary is considered a CFC, a U.S. Person that is treated as owning 10% or more of AGL’s shares may be required to include in income for U.S. federal income tax purposes its pro rata share of certain income of AGL and its non-U.S. subsidiaries for a taxable year, even if such income is not distributed and may be subject to U.S. federal income tax on a portion of any gain upon a sale or other disposition of its shares at ordinary income tax rates.

No assurance may be given that a U.S. Person who owns the Company’s shares will not be characterized as owning 10% or more of AGL and/or its non-U.S. subsidiaries under the CFC rules, in which case such U.S. Person may be subject to taxation under such rules. See Item 1. Business — Tax Matters, — Taxation of Shareholders ─ United States Taxation ─ Classification of AGL or its Non-U.S. Subsidiaries as a CFC.

U.S. Persons who hold shares may be subject to U.S. income taxation at ordinary income rates on their proportionate share of the Company’s RPII.

If any Foreign Insurance Subsidiary generates RPII (broadly defined as insurance and related investment income attributable to the insurance of a U.S. shareholder and certain related persons to such shareholder) and certain exceptions are not met, each U.S. Person owning AGL shares (directly or indirectly through foreign entities) may be required to include in income for U.S. federal income tax purposes its pro rata share of the Foreign Insurance Subsidiary’s RPII, regardless of whether such income is distributed and may be subject to U.S. federal income tax on a portion of any gain upon a sale or other disposition of its shares at ordinary tax rates (even if an exception to the RPII rules applies).

The Company believes that each of its Foreign Insurance Subsidiaries should qualify for an exception to the RPII rules and the rules that subject gain on sale or disposition of shares to ordinary tax rates would not apply to the disposition of AGL shares. However, the Company cannot be certain that this will be the case because some of the factors which determine the extent of RPII may be beyond its control and rules regarding the treatment of gain on disposition of shares have not been interpreted or finalized. Proposed regulations could, if finalized in their current form, substantially expand the definition of RPII to include insurance income of the Company’s Foreign Insurance Subsidiaries related to affiliate reinsurance transactions. If these proposed regulations are finalized in their current form, it could limit the Company’s ability to execute affiliate reinsurance transactions that would otherwise be undertaken for non-tax business reasons in the future and could increase the risk that gross RPII could constitute 20% or more of the gross insurance income of one or more of the Company’s Foreign Insurance Subsidiaries in a particular taxable year, which could result in such RPII being taxable to U.S. Persons that own or are treated as owning shares of AGL. U.S. Persons owning or treated as owning shares of AGL should consult their tax advisors as to the effect of these uncertainties. See Item 1. Business — Tax Matters — Taxation of Shareholders — United States Taxation — The RPII CFC Provisions; Disposition of AGL Shares.

U.S. tax-exempt shareholders may be subject to the unrelated business taxable income rules with respect to certain insurance income of the Foreign Insurance Subsidiaries.

U.S. tax-exempt shareholders may be required to treat insurance income includable under the CFC or RPII rules as unrelated business taxable income. See Item 1. Business — Tax Matters — Taxation of Shareholders — United States Taxation — Tax-Exempt Shareholders.

U.S. Persons who hold AGL’s shares will be subject to adverse tax consequences if AGL is considered to be PFIC for U.S. federal income tax purposes.

If AGL is considered a PFIC for U.S. federal income tax purposes, a U.S. Person who owns any shares of AGL will be subject to adverse tax consequences that could materially adversely affect its investment, including subjecting the investor to both a greater tax liability than might otherwise apply and an interest charge or other unfavorable rules (either a mark-to-market or current inclusion regime). The Company believes that AGL was not a PFIC for U.S. federal income tax purposes for taxable years through 2025 and, based on the application of certain PFIC look-through rules and the Company’s plan of operations for the current and future years, should not be a PFIC in the future. See Item 1. Business — Tax Matters — Taxation of Shareholders — United States Taxation — Passive Foreign Investment Companies.

Changes in U.S. federal income tax law may adversely affect the Company and an investment in AGL’s common shares.

The tax treatment of non-U.S. companies and their U.S. and non-U.S. subsidiaries may be the subject of future legislation that could have an adverse impact on the Company and/or its shareholders. For example, U.S. federal income tax laws and interpretations regarding whether a company is engaged in a trade or business within the U.S. or is a PFIC, or whether U.S. Persons would be required to include in their gross income the “subpart F income” of a CFC or RPII CFC are subject to change, possibly on a retroactive basis. The Company cannot be certain if, when, or in what form any future regulations or pronouncements may be implemented or made, or whether such guidance will have a retroactive effect. See Item 1. Business — Tax Matters — United States Tax Reform.

An ownership change under Section 382 of the Code could have adverse U.S. federal tax consequences.

If AGL were to issue equity securities in the future, including in connection with any strategic transaction, or if previously issued securities of AGL were to be sold by the current holders, AGL may experience an “ownership change” within the meaning of Section 382 of the Code. In general terms, an ownership change would result from transactions increasing the aggregate ownership of certain holders in AGL’s shares by more than 50 percentage points over a testing period (generally three years). If an ownership change occurred, the Company’s ability to use certain tax attributes, including certain built-in

losses, credits, deductions or tax basis and/or the Company’s ability to continue to reflect the associated tax benefits as assets on AGL’s balance sheet, may be limited. The Company cannot give any assurance that AGL will not undergo an ownership change at a time when these limitations could materially adversely affect the Company’s financial condition.

A change in AGL’s U.K. tax residence or its ability to otherwise qualify for the benefits of income tax treaties to which the U.K. is a party could adversely affect an investment in AGL’s common shares.

AGL is not incorporated in the U.K. and, accordingly, is only resident in the U.K. for U.K. tax purposes if it is “centrally managed and controlled” in the U.K. Central management and control constitutes the highest level of control of a company’s affairs. AGL believes it is entitled to take advantage of the benefits of income tax treaties to which the U.K. is a party on the basis that it is has established central management and control in the U.K. In 2013, AGL obtained confirmation that there was a low risk of challenge to its residency status from HMRC on the facts as they were at that time. The Board intends to manage the affairs of AGL in such a way as to maintain its status as a company that is tax resident in the U.K. for U.K. tax purposes and to qualify for the benefits of income tax treaties to which the U.K. is a party. However, the concept of central management and control is a case-law concept that is not comprehensively defined in U.K. statute. In addition, it is a question of fact. Moreover, tax treaties may be revised in a way that causes AGL to fail to qualify for benefits thereunder. Accordingly, a change in relevant U.K. tax law or in tax treaties to which the U.K. is a party, or in AGL’s central management and control as a factual matter, or other events, could adversely affect the ability of Assured Guaranty to manage its capital in the efficient manner that it contemplated in establishing U.K. tax residence.

Changes in U.K. tax law or in AGL’s ability to satisfy all the conditions for exemption from U.K. taxation on dividend income or capital gains in respect of its direct subsidiaries could affect an investment in AGL’s common shares.

As a U.K. tax resident, AGL is subject to U.K. corporation tax in respect of its worldwide profits (both income and capital gains), subject to applicable exemptions.

•With respect to income, the dividends that AGL receives from its subsidiaries should be exempt from U.K. corporation tax under the exemption contained in section 931D of the Corporation Tax Act 2009.

•With respect to capital gains, if AGL were to dispose of shares in its direct subsidiaries or if it were deemed to have done so, it may realize a chargeable gain for U.K. tax purposes. Any tax charge would be based on AGL’s original acquisition cost. It is anticipated that any such future gain should qualify for exemption under the substantial shareholding exemption in Schedule 7AC to the Taxation of Chargeable Gains Act 1992. However, the availability of such exemption would depend on facts at the time of disposal, in particular the “trading” nature of the relevant subsidiary. There is no statutory definition of what constitutes “trading” activities for this purpose and in practice reliance is placed on the published guidance of HMRC.

A change in U.K. tax law or its interpretation by HMRC, or any failure to meet all the qualifying conditions for relevant exemptions from U.K. corporation tax, could affect Assured Guaranty’s financial results of operations or its ability to provide returns to shareholders.

An adverse adjustment under U.K. legislation governing the taxation of U.K. tax resident holding companies on the profits of their non-U.K. subsidiaries could adversely impact Assured Guaranty’s tax liability.

Under the U.K. “controlled foreign company” regime, the income profits of non-U.K. resident companies may, in certain circumstances, be attributed to controlling U.K. resident shareholders for U.K. corporation tax purposes. The non-U.K. resident members of the Assured Guaranty group intend to operate and manage their levels of capital in such a manner that their profits would not be taxed on AGL under the U.K. CFC regime. In 2013, Assured Guaranty obtained clearance from HMRC that none of the profits of the non-U.K. resident members of the Assured Guaranty group should be subject to U.K. tax as a result of attribution under the CFC regime on the facts as they were at the time. However, a change in the way in which Assured Guaranty operates or any further change in the CFC regime, resulting in an attribution to AGL of any of the income profits of AGL’s non-U.K. resident subsidiaries for U.K. corporation tax purposes, could adversely affect Assured Guaranty’s financial results of operations.

An adverse adjustment under U.K. transfer pricing legislation or the imposition of diverted profits tax could adversely impact Assured Guaranty’s tax liability.

If any arrangements between U.K. resident companies in the Assured Guaranty group and other members of the Assured Guaranty group (whether resident in or outside the U.K.) are found not to be on arm's length terms and as a result a U.K. tax advantage is being obtained, an adjustment will be required to compute U.K. taxable profits as if such arrangement

were on arm's length terms. Any transfer pricing adjustment could adversely affect Assured Guaranty’s results of operations. Further, following consultation in Spring 2025, on December 4, 2025, the U.K. government published the draft Finance Bill which repeals the law relating to diverted profits tax and incorporates analogous anti-avoidance measures within the U.K.'s transfer pricing regime. Pursuant to the new charging provisions, if a company within the charge to U.K. corporation tax has "unassessed transfer pricing profits" (UTPP) such profits may be subject to corporation tax at the higher “UTPP rate” (currently 31%). If any U.K. resident company in the Assured Guaranty group is liable to corporation tax at the UTPP rate, this could adversely affect the Company's results of operations.

Since January 1, 2016, the U.K. has implemented a country-by-country reporting (CBCR) regime whereby large multi-national enterprises are required to report details of their operations and intra-group transactions in each jurisdiction. The U.K. CBCR legislation includes power to introduce regulations requiring public disclosure of U.K. CBCR reports, although this power has not yet been exercised. It is possible that Assured Guaranty’s approach to transfer pricing may become subject to greater scrutiny from the tax authorities in the jurisdictions in which the group operates in consequence of the implementation of a CBCR regime in the U.K. (or other jurisdictions).

Assured Guaranty’s financial results may be affected by measures taken in response to the OECD BEPS project.

The Organization for Economic Cooperation and Development (OECD) has developed guidance known as base erosion and profit shifting as part of its initiative to address corporate tax planning strategies used by some multinationals to shift profits from higher-tax jurisdictions to lower-tax jurisdictions or no-tax jurisdictions. This guidance generally imposes rules with a global minimum tax of 15%, and many jurisdictions have enacted implementing legislation or are in the course of doing so. In particular, the U.K. enacted legislation in July 2023 and February 2024, and HMRC published guidance in respect of such legislation which broadly implement the OECD’s guidance into U.K. domestic legislation of accounting periods starting on or after December 31 2023. In addition, in December 2023 the Government of Bermuda adopted legislation for a corporate income tax which would share many key concepts with the Model Rules and is intended to constitute a “covered tax” for the purposes of the Model Rules. See “– AGL may become, and AG Re and AGRO are, subject to taxes in Bermuda, which may adversely affect the Company’s future results of operations and an investment in the Company” above. In many countries, the rules will apply from January 1, 2024, although some jurisdictions have elected to postpone for one year or more.

In January 2025, the OECD issued Administrative Guidance on Article 9.1 of the Global Anti-Base Erosion Model Rules, which excludes certain deferred tax assets for purposes of computing a multinational enterprise group’s effective tax rate when they arose prior to the application of the global minimum tax as a result of certain governmental arrangements or following the introduction of a new corporate income tax. If this guidance were adopted in countries in which the Company operates it could adversely affect tax expense.

The Company’s analysis is ongoing as the OECD continues to release additional guidance, countries enact legislation, and the U.S. formulates its potential response. To the extent additional legislative changes take place in the countries in which the Company operates, it is possible that they will alter long-standing tax principles, be highly complex and be subject to differing applications and interpretations across jurisdictions. Although the Company cannot predict the approach of each relevant jurisdiction to the OECD’s framework, their implementation could adversely affect Assured Guaranty’s tax liability.

Risks Related to Applicable Law, Litigation and GAAP

Changes in, or inability to comply with, applicable laws and regulations could adversely affect the Company’s financial condition, results of operations, capital, liquidity, business prospects and share price.

The Company’s businesses are subject to detailed insurance, asset management and other financial services laws and government regulations in the jurisdictions in which they operate. In the U.S., financial guaranty insurers are subject to specific regulatory requirements and limitations applicable to their portfolios of outstanding insured obligations, consisting of single risk limits, aggregate risk limits, exposure limits to municipal (and related) obligations that lack an underlying investment grade NRSRO or SVO designation, and exposure limits to non-U.S. dollar insured obligations. Such insurers also must comply with specific regulatory requirements and limitations applicable to their investment portfolios, including limits on the portion of such portfolio rated BIG or non-rated. While the Company’s U.S. financial guaranty insurer, AG, manages these requirements, it is possible for the limitations to be exceeded for several reasons, including a strategic acquisition of a financial guaranty insurance company (or reinsurance of a company’s insured portfolio) by AG increasing concentrations of AG’s insurance exposures, decline of AG’s statutory capital (against which single risk and aggregate risk limits are measured), deterioration of AG’s insurance portfolio, foreign exchange fluctuations, downgrades of AG’s investment grade investments or positive returns in AG’s non-rated alternative investments (thereby increasing the valuation of such investments on its balance sheet). In addition to the insurance, asset management and other regulations and laws specific to the industries in which the Company operates or

invests, regulatory agencies in jurisdictions in which the Company’s businesses operate have broad administrative power over many aspects of the Company’s business, which may include ethical issues, money laundering, cybersecurity, privacy, recordkeeping and marketing and sales practices.

Noncompliance with applicable laws or regulations, or future changes to laws or regulations in the jurisdictions in which the Company does business, may adversely affect the Company’s financial condition, results of operations, capital, liquidity, business prospects and share price. If the Company fails to comply with applicable laws or regulations it could be exposed to fines, the loss of licenses, including insurance licenses, limitations on the right to originate new business and restrictions on its ability to pay dividends. If an insurance subsidiary’s surplus declines below minimum required levels, the insurance regulator could impose additional restrictions on the insurance subsidiary or initiate insolvency proceedings. Future changes to laws and regulations may, among other things, limit the types of risks the Company may insure, lower applicable single or aggregate risk limits related to its insurance business, increase required reserves or capital for its insurance subsidiaries, provide insured obligors with additional avenues for avoiding or restructuring the repayment of their insured liabilities, increase the level of supervision or regulation to which the Company’s operations may be subject, impose restrictions that make the Company’s products less attractive to potential buyers and investors, and require the Company to change certain of its business practices exposing it to additional costs (including increased compliance costs).

Changes in applicable laws or regulations or governmental policies may adversely impact the ability of issuers to satisfy obligations insured or reinsured by the Company.

Certain issuers of obligations insured or reinsured by the Company are reliant on governmental subsidies, funding, grants, loans and other forms of financial assistance, including, for example, emergency funding for disasters and catastrophes, regulated subsidies paid to utilities, housing subsidies and federal aid for schools. In addition, certain issuers of obligations insured or reinsured by the Company may rely on current federal, state and local tax laws (such as tariff regimes impacting imports and the transportation sector) and/or on legal and regulatory frameworks impacting their businesses (for example, the healthcare industry’s development around, and reliance on, Medicaid, Medicare and the Affordable Care Act). If current laws or regulations or governmental policies impacting issuers of obligations in the Company’s insurance portfolio are changed in a manner adversely impacting such issuers (for example, nationalization of assets) and/or governmental financial assistance supporting such issuers is reduced or eliminated, the Company may experience increased levels of losses or claims on its insured obligations.

Legislation, regulation, determinations made by legal or regulatory authorities, or litigation arising out of the struggles of distressed obligors may adversely impact obligations insured or reinsured by the Company, the Company’s legal rights as creditor and its investments.

Borrower distress or default, whether or not the relevant obligation is insured by one of the Company’s insurance subsidiaries, may result in legislation, regulation, legal or regulatory determinations, or litigation that may adversely impact obligations insured or reinsured by the Company, the Company’s legal rights as creditor and its investments. For example, the default by the Commonwealth of Puerto Rico on much of its debt has resulted in both legislation (including the enactment of PROMESA) and litigation that is continuing to impact the Company’s rights as creditor.

The Company is, and may be in the future, involved in litigation, both as a defendant and as a plaintiff, in the ordinary course of its insurance and asset management business and other business operations. The outcome of such litigation could materially impact the Company’s expected losses and results of operations and cash flows. For a discussion of material litigation, see Part II, Item 8. Financial Statements and Supplementary Data, Note 4. Expected Loss to be Paid (Recovered), and Note 17. Contingencies.

AGL’s ability to pay dividends and fund share repurchases and other activities may be constrained by certain insurance regulatory requirements and restrictions.

AGL is subject to Bermuda regulatory requirements that affect its ability to pay dividends on common shares and to make other payments. Under the Bermuda Companies Act 1981, as amended, AGL may declare or pay a dividend only if it has reasonable grounds for believing that it is, and after the payment would be, able to pay its liabilities as they become due, and if the realizable value of its assets would not be less than its liabilities. While AGL currently intends to pay dividends on its common shares, investors who require dividend income should carefully consider these risks before investing in AGL.

AGL is dependent on dividends from its subsidiaries, including dividends from its insurance subsidiaries, for resources to pay holders of its common shares, fund share repurchases and pursue other activities. The ordinary dividends that AGL’s insurance subsidiaries may pay without regulatory approval are subject to legal and regulatory limitations. See Item 1. Business

– Regulation – State Dividend Limitations, Item 1. Business – Regulation – Non-U.S. Regulation – Bermuda – Restrictions on Dividends and Distributions, Item 1. Business – Regulation – Non-U.S. Regulation – United Kingdom Insurance and Financial Services Regulation – Restrictions on Dividend Payments and Item 1. Business – Regulation – Non-U.S. Regulation – France – Restrictions on Dividend Payments. As a result, absent relief from the relevant regulator(s), the Company’s insurance subsidiaries may be required to retain capital that is substantially in excess of what the Company believes is necessary to support its insurance businesses, reducing the Company’s ability to productively use or return to shareholders such excess capital. In addition, if, pursuant to insurance laws and regulations, AGL’s insurance subsidiaries are not permitted to pay ordinary dividends or make other permitted payments to their holding companies at the times or in sufficient amounts AGL requires to fund its activities, and if AGL’s other operating subsidiaries were unable to provide such funds, AGL’s ability to pay dividends to shareholders or fund share repurchases or pursue other activities could be adversely affected. See “— Operational Risks — The ability of AGL and its subsidiaries to meet their liquidity needs may be limited.”

Applicable insurance laws may make it difficult to effect a change of control of AGL.

Before a person can acquire control of a U.S., U.K. or French insurance company, prior written approval must be obtained from the relevant regulatory commissioner or superintendent of the state or country where the insurer is domiciled. In addition, once a person controls a Bermuda insurance company, the Authority may object to such a person who is not, or is no longer, a fit and proper person to exercise such control. Because a person acquiring 10% or more of AGL’s common shares would indirectly control the same percentage of the stock of its insurance subsidiaries, the insurance change of control laws of Maryland, the U.K., France and Bermuda would likely apply to such a transaction. These laws may discourage potential acquisition proposals and may delay, deter or prevent a change of control of AGL, including through transactions, and in particular unsolicited transactions, that some or all of its shareholders might consider to be desirable. While AGL’s Bye-Laws limit the voting power of any shareholder to less than 10%, the Company cannot provide assurances that the applicable regulatory bodies would agree that a shareholder who owned 10% or more of its common shares did not control the applicable insurance subsidiaries, notwithstanding the limitation on the voting power of such shares.

An inability to obtain accurate and timely financial information from Sound Point or other alternative investment managers may impair the Company’s ability to comply with reporting obligations under federal securities law.

The Company will be reliant on Sound Point and other alternative investment managers to provide accurate and timely financial reporting that will allow the Company to timely prepare and file its own financial statements in accordance with generally accepted accounting principles in the United States (GAAP) and in compliance with SEC regulations and NYSE listing rules.

As private companies, Sound Point and other alternative investment managers are generally not required to prepare their financial statements in compliance with the SEC’s accounting regulations and timelines. The Company expects to report certain of its investments in Sound Point, the Sound Point funds, other vehicles and separately managed accounts and other alternative investment funds on a one-quarter lag. While each of Sound Point, other alternative investment managers and their respective related parties have agreed to provide to the Company financial information necessary to complete and file its periodic SEC reports on a timely basis, any failure by Sound Point, other alternative investment managers or their respective related parties to provide the Company with accurate and timely financial information could result in a delay in the Company’s timely reporting of its results of operations or it not filing one or more periodic reports with the SEC on time or inaccuracies in its financial statements.

Changes in the fair value of the Company’s insured credit derivatives portfolio, CCS, FG VIEs, alternative investments, including those accounted for as CIVs, and/or the consolidation or deconsolidation of one or more FG VIEs and/or CIVs during a financial reporting period, may subject its results of operations to volatility.

The Company is required to mark-to-market certain derivatives that it insures, including CDS that are considered derivatives under GAAP, as well as its CCS. Although there is no cash flow effect from this “marking-to-market,” net changes in the fair value of these derivatives are reported in the Company’s consolidated statements of operations and therefore affect its results of operations. If a credit derivative is held to maturity and no credit loss is incurred, any unrealized gains or losses previously reported would be reversed as the transaction reaches maturity. The Company also expects fluctuations in the fair value of its put option under its CCS to reverse over time. For discussion of the Company’s fair value methodology for credit derivatives, see Part II, Item 8. Financial Statements and Supplementary Data, Note 9. Fair Value Measurement.

The Company is required to consolidate certain VIEs, which generally consist of (1) entities to which it has provided financial guaranties and (2) funds and vehicles in which it invests, such as those managed by Sound Point (and, prior to July 1, 2023, AssuredIM), if it concludes that it is the primary beneficiary of such VIE. Substantially all of the assets and liabilities of

the consolidated FG VIEs and CIVs are reported at fair value. The Company continuously evaluates its power to direct the activities that most significantly impact the economic performance of VIEs and, if circumstances change, may consolidate a VIE that was not previously consolidated or deconsolidate a VIE that had previously been consolidated, and such consolidation or deconsolidation would impact its financial condition and results of operations in the period in which such action is taken. See Part II, Item 8. Financial Statements and Supplementary Data, Note 8. Variable Interest Entities.

The required treatment under GAAP of the Company’s insured credit derivatives portfolio, its CCS and its VIEs causes its financial condition and results of operations as reported under GAAP to be more volatile than would be suggested by the actual performance of its business operations. Due to the complexity of fair value methodologies and the application of GAAP requirements, future amendments or interpretations of relevant accounting standards may cause the Company to modify its accounting methodology in a manner which may have an adverse impact on its financial results.

Change in industry and other accounting practices could adversely affect the Company’s financial condition, results of operations, business prospects and share price.

Changes in or the issuance of new U.S. GAAP accounting standards or statutory accounting standards in the jurisdictions in which the Company is domiciled, such as those that affect the measurement, amount and/or timing of revenue or loss recognition, or those that limit the admissibility of certain assets, among others, could adversely affect the Company’s financial condition, results of operations, business prospects and share price and or the insurance subsidiaries’ ability to pay dividends to AGMH, and ultimately, to AGL. See, Part II, Item 8. Financial Statements and Supplementary Data, Note 1. Business and Basis of Presentation, for a discussion of the future application of accounting standards.

Risks Related to AGL’s Common Shares

The market price of AGL’s common shares may be volatile, and the value of an investment in the Company may decline.

The market price of AGL’s common shares has experienced, and may continue to experience, significant volatility. Numerous factors, including many over which the Company has no control, may have a significant impact on the market price of its common shares. These risks include those described or referred to in this “Risk Factors” section as well as, among other things: (a) investor perceptions of the Company, its prospects and that of the financial guaranty, life and annuity reinsurance and asset management industries and the markets in which the Company operates; (b) the Company’s operating and financial performance; (c) the Company’s access to financial and capital markets to raise additional capital, refinance its debt or obtain other financing; (d) Company’s ability to repay debt; (e) the Company’s dividend policy; (f) the amount of share repurchases authorized by the AGL’s Board; (g) future sales of equity or equity-related securities; (h) changes in earnings estimates or buy/sell recommendations by analysts; and (i) general financial, economic and other market conditions.

In addition, the stock market in recent years has experienced extreme price and trading volume fluctuations that often have been unrelated or disproportionate to the operating performance of individual companies. These broad market fluctuations may adversely affect the price of AGL’s common shares, regardless of AGL-specific factors.

Furthermore, future sales or other issuances of AGL equity may adversely affect the market price of its common shares.

Provisions in the Code and AGL’s Bye-Laws may reduce the voting rights of its common shares.

Under the Code, AGL’s Bye-Laws and contractual arrangements, certain shareholders have their voting rights limited to less than one vote per share. Moreover, the relevant provisions of the Code and AGL’s Bye-Laws may have the effect of reducing the votes of certain shareholders who would not otherwise be subject to the limitation by virtue of their direct share ownership.

More specifically, pursuant to the relevant provisions of the Code, if, and so long as, the common shares of a shareholder are treated as “controlled shares” (as determined under section 958 of the Code) of any U.S. Person and such controlled shares constitute 9.5% or more of the votes conferred by AGL’s issued shares, the voting rights with respect to the controlled shares of such U.S. Person (a 9.5% U.S. Shareholder) are limited, in the aggregate, to a voting power of less than 9.5%, under a formula specified in AGL’s Bye-Laws. The formula is applied repeatedly until the voting power of all 9.5% U.S. Shareholders has been reduced to less than 9.5%. For these purposes, “controlled shares” include, among other things, all shares of AGL that such U.S. Person is deemed to own directly, indirectly or constructively (within the meaning of section 958 of the Code).

In addition, the Board may limit a shareholder’s voting rights where it deems appropriate to do so to: (1) avoid the existence of any 9.5% U.S. Shareholders; and (2) avoid certain material adverse tax, legal or regulatory consequences to the Company or any of the Company’s subsidiaries or any shareholder or its affiliates. AGL’s Bye-Laws provide that shareholders will be notified of their voting interests prior to any vote taken by them.

AGL also has the authority under its Bye-Laws to request information from any shareholder for the purpose of determining whether a shareholder’s voting rights are to be reduced under the Bye-Laws. If a shareholder fails to respond to a request for information or submits incomplete or inaccurate information in response to a request, the Company may, in its sole discretion, eliminate such shareholder’s voting rights.

Provisions in AGL’s Bye-Laws may restrict the ability to transfer common shares, and may require shareholders to sell their common shares.

AGL’s Board may decline to approve or register a transfer of any common shares: (1) if it appears to the Board, after taking into account the limitations on voting rights contained in AGL’s Bye-Laws, that any adverse tax, regulatory or legal consequences to AGL, any of its subsidiaries or any of its shareholders may occur as a result of such transfer (other than such as the Board considers to be de minimis); or (2) subject to any applicable requirements of or commitments to the NYSE, if a written opinion from counsel supporting the legality of the transaction under U.S. securities laws has not been provided or if any required governmental approvals have not been obtained.

AGL’s Bye-Laws also provide that if the Board determines that share ownership by a person may result in adverse tax, legal or regulatory consequences to the Company, any of the subsidiaries or any of the shareholders (other than such as the Board considers to be de minimis), then AGL has the option, but not the obligation, to require that shareholder to sell to AGL or to third parties to whom AGL assigns the repurchase right for fair market value the minimum number of common shares held by such person which is necessary to eliminate such adverse tax, legal or regulatory consequences.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 1C. CYBERSECURITY

Risk Management and Strategy

The Company has strategically integrated cybersecurity risk management into its broader risk management framework to promote a company-wide culture of cybersecurity risk management. This integration ensures that cybersecurity considerations are an integral part of the Company’s decision-making processes. The Company regularly assesses risks from cybersecurity threats and monitors its computer networks for vulnerabilities. To defend the Company’s computer systems from cyberattacks, the Company uses various security tools that are designed to help the Company protect against, identify, monitor, escalate, investigate, resolve, and recover from security incidents in a timely manner.

The Company maintains an Information Security Policy and Standards that details how material risks from cybersecurity threats are assessed, identified, and managed:

•Risk assessment – a periodic risk assessment is performed by the Chief Information Security Officer using the National Institute of Standards and Technology cybersecurity framework and rates risks by criticality.

•Risk identification – vulnerabilities and risks are identified through functions performed by the Chief Information Security Officer which includes assessments using automated tools, monitoring activities, reviewing threat intelligence, and responding to incidents. Risks are also identified through independent assessments performed by third-party consultants and the internal audit function.

•Risk management – the Chief Technology Officer oversees a process designed to protect against and remediate risks according to their criticality and presents to the Risk Oversight and Audit Committees of the Board and management at least semi-annually. The Chief Information Security Officer also presents to the Board and Risk Oversight Committee on information technology, cybersecurity and data privacy matters at least annually.

The Company’s Information Security Policy and Standards details a process for responding to cybersecurity events. Awareness and alertness are important components of the Company’s cybersecurity program; each year employees are required to take the cybersecurity training and the Company conducts regular exercises to educate employees about best practices and help them identify and avoid potential threats.

The Company engages third-party consultants to conduct periodic penetration testing designed to identify potential security vulnerabilities. The Company’s internal audit function, which has been outsourced to an international accounting firm, conducts periodic audits of cybersecurity and reports on such matters to the Audit Committee of the Board.

The Company takes measures designed to mitigate risks associated with third-party vendors that have access to confidential information or provide business critical functions. Through its vendor management program, the Company screens these third-party vendors to assess their data security protocols both prior to initial engagement and periodically thereafter for compliance with the program standards. The Company seeks contractual obligations from third-party vendors to notify it in the event of a cybersecurity incident, and monitors threat intelligence reports as well as current reports of SEC-registered vendors and their sub-service providers that have access to confidential information or provide business critical functions for cybersecurity incidents.

The Company has not experienced any cybersecurity incidents that have materially affected, or that it believes are reasonably likely to materially affect, the Company, including its business strategy, results of operations, or financial condition.

Governance

Under the Company’s cybersecurity governance framework, the Board has overall responsibility for overseeing management’s establishment and operation of a cybersecurity program. Members of the Board have broad-based skills in risk management oversight and/or cybersecurity oversight certifications. The Board delegates certain cybersecurity oversight responsibilities to the Risk Oversight Committee, which oversees enterprise risk, vendor management, and information technology risks, including assessing and managing cybersecurity and data privacy risks, and to the Audit Committee, whose oversight responsibility includes, as part of its oversight of the Company’s system of internal controls over financial reporting, assessing and managing financial risk exposures, including information technology, cybersecurity and data privacy risk related to the Company’s financial systems. The Risk Oversight Committee has specific responsibility for overseeing information technology processes and controls, including for cybersecurity, data privacy, compliance with related policies, and the process to monitor risks to the Company arising from changing technology trends, and coordinates with the Audit Committee, as needed.

The security of the Company’s products, services and corporate network is a key priority both for the growth of the Company’s business and its responsibilities as the leading financial guaranty insurance company. The Company takes a risk-based approach to cybersecurity and has implemented cybersecurity policies throughout its operations.

As described above in Cybersecurity – Risk Management and Strategy, the Company’s Chief Technology Officer has management responsibility for overseeing a process designed to remediate cybersecurity risks, and reports to the Board, Risk Oversight Committee, Audit Committee and management at least semi-annually. The Chief Technology Officer reported to the Board, Risk Oversight Committee and Audit Committee four times in 2025. The Chief Technology Officer has over 25 years of experience in information technology, technology research and security and operations management, with over 15 of those years focused in financial services and insurance. The Chief Technology Officer holds a Master of Science in Information Systems and a Master of Business Administration with a focus in Management and Operations. The Company has appointed a Chief Information Security Officer, who is responsible for leading the assessment and management of cybersecurity risk. In 2025, the Chief Information Security Officer made an annual report on information technology and cybersecurity risks to the Board and made four quarterly reports to the Risk Oversight Committee and the Audit Committee. The Chief Information Security Officer has over 25 years of experience in information security and is a Certified Information Systems Security Professional (CISSP), Certified Information Security Manager (CISM), and Certified Information Systems Auditor (CISA). The Chief Information Security Officer reports to the Board, its committees, and management on cybersecurity threats on a regular basis.

The Company uses various tools to prevent, detect, and mitigate cybersecurity incidents. The Company has procedures in place to respond to cybersecurity incidents, which include prompt meeting of the Cybersecurity Incident Disclosure Committee, a Company management committee, to assess cybersecurity incidents and determine materiality requiring disclosure on Form 8-K, notification to the Board of any material cybersecurity incidents, quarterly reporting by the Chief Information Security Officer of material and non-material incidents to the Risk Oversight Committee and management, and to the Audit Committee of such incidents related to the Company’s financial systems.

PART II

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER PURCHASES OF EQUITY SECURITIES

AGL’s common shares are listed on the NYSE under the symbol “AGO.” On February 25, 2026, the approximate number of shareholders of record at the close of business on that date was 79.

AGL is a holding company whose principal source of liquidity is dividends from its operating subsidiaries. The ability of the operating subsidiaries to pay dividends to AGL and AGL’s ability to pay dividends to its shareholders are each subject to legal and regulatory restrictions. The declaration and payment of future dividends will be at the discretion of AGL’s Board and will be dependent upon the Company’s profits and financial requirements and other factors, including legal restrictions on the payment of dividends and such other factors as the Board deems relevant. AGL paid quarterly cash dividends in the amount of $0.34 and $0.31 per common share in 2025 and 2024, respectively. For more information concerning AGL’s dividends, see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources and Item 8. Financial Statements and Supplementary Data, Note 18. Shareholders’ Equity.

Issuer’s Purchases of Equity Securities

In 2025, the Company repurchased a total of 5,819,627 common shares for $500 million at an average price of $85.92 per share.

From time to time, the Board authorizes the repurchase of additional common shares under a program without an expiration date that it initiated on January 18, 2013. Most recently, on November 5, 2025, the Board authorized the repurchase of an additional $100 million of its common shares. As of February 25, 2026, the remaining amount the Company was authorized to purchase was $204 million of its common shares. The Company expects future common share repurchases under the current authorization to be made from time to time in the open market or in privately negotiated transactions. The timing, form and amount of the share repurchases are at the discretion of management and will depend on a variety of factors, including availability of funds at the holding companies, other potential uses for such funds, market conditions, the Company’s capital position, legal requirements and other factors. The repurchase authorization may be modified, extended or terminated by the Board at any time. It does not have an expiration date. See Item 8. Financial Statements and Supplementary Data, Note 18. Shareholders’ Equity, for additional information about share repurchases and authorizations.

The following table reflects purchases of AGL common shares made by the Company during the fourth quarter of 2025.


Period	Total Number of Shares Purchased (1)	Average Price Paid Per Share		Total Number of Shares Purchased as Part of Publicly Announced Program (2)	Maximum Number (or Approximate Dollar Value) of Shares that May Yet Be Purchased Under the Program (3)
October 1 - October 31	558,800	$	82.25	558,800	$	236,989,639
November 1 - November 30	502,229	$	86.78	502,229	$	293,408,392
December 1 - December 31	462,744	$	90.22	462,744	$	251,658,618
Total	1,523,773	$	86.16	1,523,773

____________________

(1) The total number of shares purchased also includes shares purchased as a result of employees surrendering shares as payment for withholding taxes upon vesting of share awards.

(2) After giving effect to repurchases since the Board first authorized the repurchase program on January 18, 2013, through February 25, 2026, the Company has repurchased a total of 157 million common shares for $5.9 billion, excluding commissions, at an average price of $37.73 per share. The repurchase program has no expiration date and the Board has periodically increased the authorization since 2013.

(3) Excludes commissions.

Performance Graph

Set forth below are a line graph and a table comparing the dollar change in the cumulative total shareholder return on AGL’s common shares from December 31, 2020 through December 31, 2025 as compared to the cumulative total return of the S&P’s 500 Stock Index, the cumulative total return of the S&P’s 500 Financials Stock Index and the cumulative total return of the Russell Midcap Index - Financials. The Company added the Russell Midcap Index - Financials in 2018 because it believes that this index, which includes the Company, provides a useful comparison to other companies in the financial services sector, and excludes companies that are included in the S&P’s 500 Financials Stock Index but are many times larger than the Company. The chart and table depict the value on December 31 of each year from 2020 through 2025 of a $100 investment made on December 31, 2020, with all dividends reinvested:


	Assured Guaranty		S&P 500 Stock Index		S&P 500 Financials Stock Index		Russell Midcap Index - Financials

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

For a more detailed description of events, trends and uncertainties, as well as the capital, liquidity, credit, operational and market risks and the critical accounting policies and estimates affecting the Company, the following discussion and analysis of the Company’s financial condition and results of operations should be read in its entirety with the Company’s consolidated financial statements and accompanying notes which appear elsewhere in this Form 10-K. The following discussion and analysis of the Company’s financial condition and results of operations contains forward looking statements that involve risks and uncertainties. See “Forward Looking Statements” for more information. The Company’s actual results could differ materially from those anticipated in these forward looking statements as a result of various factors, including those discussed below and elsewhere in this Form 10-K, particularly under the headings “Risk Factors” and “Forward Looking Statements.”

Discussion related to the results of operations for the Company’s comparison of 2024 results to 2023 results have been omitted in this Form 10-K. The Company’s comparison of 2024 results to 2023 results is included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, under Part II, Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

Overview

Business

The Company reports its results of operations in two distinct segments, Insurance and Asset Management, consistent with the manner in which the Company’s chief operating decision maker reviews the business to assess performance and allocate resources. The Company’s Corporate division and other activities (including financial guaranty VIEs (FG VIEs) and CIVs) are presented separately.

In the Insurance segment, the Company provides credit protection products to the U.S. and non-U.S. public finance (including infrastructure) and structured finance markets. The Company participates in the asset management business through its ownership interest in Sound Point. See Part I, Item 1. Business – Asset Management, and Item 8. Financial Statements and Supplementary Data, Note 1. Business and Basis of Presentation.

The Corporate division primarily consists of the results of holding companies that have issued public equity or debt. The Other category primarily includes the effect of consolidating FG VIEs and CIVs (FG VIE and CIV consolidation). See Item 8. Financial Statements and Supplementary Data, Note 2. Segment Information.

Financial Strength Ratings

Demand for the financial guaranties issued by the Company’s financial guaranty insurance subsidiaries may be impacted by changes in the credit ratings assigned to them by the rating agencies. The financial strength ratings (or similar ratings) assigned to AGL’s financial guaranty insurance subsidiaries, along with the date of the most recent rating action (or confirmation) by the rating agency assigning the rating, are shown in the table below.

In addition, the Company’s life and annuity reinsurance subsidiary, Assured Life Re, is rated BBB (Outlook Positive) (1/28/26) by Fitch Ratings, Inc.

Ratings are subject to continuous rating agency review and revision or withdrawal at any time. In addition, the Company periodically assesses the value of each rating assigned to each of its companies, and as a result of such assessment may request that a rating agency add or drop a rating from certain of its companies. There can be no assurance that any of the rating agencies will not take negative action on the financial strength ratings (or similar ratings) of AGL’s insurance

subsidiaries in the future or cease to rate one or more of AGL’s insurance subsidiaries, either voluntarily or at the request of that subsidiary.

For a discussion of the effects of rating actions on the Company beyond potential effects on the demand for its insurance products, see Part I, Item 1A. Risk Factors – Strategic Risks captioned “A downgrade of the financial strength or financial enhancement ratings of any of the Company’s insurance or reinsurance subsidiaries may adversely affect its business prospects.”

Economic Environment

On April 2, 2025, the U.S. administration announced a “reciprocal tariff” strategy under the authority of the International Emergency Economic Powers Act (IEEPA) entailing extensive global tariff increases, with the objective of rectifying trade practices that contribute to large and persistent annual U.S. goods trade deficits. The announcement of global tariffs disrupted international trade, sent shocks through the global economy, and heightened volatility in the financial markets. The U.S. subsequently postponed newly announced reciprocal tariffs, which took effect on August 7, 2025. On August 29, 2025, the U.S. Court of Appeals for the Federal Circuit ruled that the U.S. administration had exceeded its authority under the IEEPA but permitted the tariffs to remain in effect to provide time for the government to appeal. The U.S. Supreme Court granted certiorari on September 9, 2025, and heard oral arguments on the case on November 5, 2025; on February 20, 2026 the U.S. Supreme Court held that the IEEPA does not authorize the President of the United States to impose tariffs. The U.S. administration has indicated that tariffs found to be illegal by the U.S. Supreme Court will be replaced with alternative import taxes as uncertainty remains. U.S. tariffs can add to inflation, and the Company believes that ongoing uncertainty may increase volatility in U.S. equities and other risk assets, curb corporate capital and consumer spending and raise the risk of recession. Market volatility and the risk of recession may impact the Company in different ways. The Company believes that a recession may make it more likely that obligors whose obligations it guarantees will default. However, market volatility may also cause credit spreads to widen as investors seek security, which tends to create new business opportunities for the Company.

Real gross domestic product (GDP) increased 2.2% in 2025, compared to an increase of 2.8% in 2024, according to the advance estimate released by the U.S. Bureau of Economic Analysis (BEA). Additionally, the BEA reported real GDP increased at an annual rate of 1.4% in the fourth quarter of 2025. At the end of December 2025, the U.S. unemployment rate, seasonally adjusted, stood at 4.4%, higher than where it started the year at 4.1%. The Company believes a more robust economy makes it less likely that obligors whose obligations it guarantees will default.

According to the U.S. Bureau of Labor Statistics, the inflation rate in the U.S. before seasonal adjustment for the 12-month period ending December 2025, as measured by the Consumer Price Index for All Urban Consumers, was 2.7%, as compared to 2.9% for the 12-month period ending December 2024. According to the U.K. Office for National Statistics, the Consumer Prices Index including owner occupiers’ housing costs rose 3.6% for the 12 months through December 2025, as compared to 3.5% for the 12 months through December 2024. Generally, inflation reduces the real value of money over time. For obligors whose payments the Company insures, inflation can mean that the real value of their fixed debt payments decreases, potentially making it relatively easier for obligors to service these fixed-rate debts and less likely for them to default. However, if inflation increases operating expenses and revenues or incomes do not keep pace, obligors may find it more difficult to make their payment obligations, even if nominal debt payments remain unchanged. Higher inflation can also lead to tighter monetary policies, which are actions taken by sovereign central banks to reduce the amount of money circulating in the economy, including raising interest rates, which can make refinancing or servicing debt more difficult. In addition, consumer price inflation in the U.K. affects reported net par outstanding for certain U.K. exposures with $24.5 billion of net par outstanding as of December 31, 2025, and also affects projected future installment premiums on the portion of such exposure that pays at least a portion of the premium on an installment basis over the term of the exposure.

At its September 2024 meeting, the Federal Open Market Committee (FOMC) decided to lower the federal funds rate, which was a reversal of the rate increases it had initiated in March 2022 to combat inflation. The federal funds rate is the rate at which banks lend to and borrow from each other, is the benchmark for most interest rates, and tends to influence mortgage rates. As the federal funds rate decreases, interest rates, including mortgage rates, tend to decrease. From September 2024 through December 2025, the FOMC lowered the federal funds rate from a target range of 5.25% to 5.50% to a range of 3.50% to 3.75%. Most recently, at its January 2026 meeting, the FOMC held the federal funds rate at a target range of 3.50% to 3.75%, stating that it is strongly committed to supporting maximum employment and returning inflation to its 2% objective. In considering the extent and timing of additional adjustments to the target range for the federal funds rate, the FOMC has indicated it will carefully assess incoming data, the evolving outlook, and the balance of risks. These assessments will take into account a wide range of information, including readings on labor market conditions, inflation pressures and inflation expectations, and financial and international developments.

From 2022 through February 2026, the Bank of England’s Monetary Policy Committee (MPC) took actions similar to those of the FOMC to combat inflation and spur economic growth. In 2022, the MPC raised the Bank of England base rate (Bank Rate) from historic lows in response to surging inflation, increasing the rate multiple times into 2023 as inflation remained high above MPC’s 2% target. By the end of 2023, the MPC signaled a pause in further increases as inflation began to decline and economic growth slowed. During 2024, as inflationary pressures eased further and the U.K. economy showed signs of stagnation or mild recession, the MPC kept the rate unchanged for most of the year, before beginning to decrease the Bank Rate in August 2024. In 2025 and early 2026, with inflation being closer to the MPC’s target level and economic growth slowed, the MPC further lowered the Bank Rate several times, standing at 3.75% as of February 5, 2026, aiming to support economic growth while maintaining price stability.

The level and direction of change of interest rates and credit spreads impact the Company in numerous ways. On the one hand, lower interest rates may increase the fair value of fixed-maturity securities currently held in the Company’s investment portfolio, encourage municipal and infrastructure bond issuance and positively impact the finances of some of the obligors whose payments the Company insures. On the other hand, lower interest rates may decrease the base on which the Company charges up-front premium on most new municipal and infrastructure bond transactions and may also decrease amounts the Company can earn on securities newly acquired for its investment portfolio. Lower interest rates also are often accompanied by narrower credit spreads, which may also decrease the level of premiums the Company can charge for transactions.

The 30-year AAA Municipal Market Data (MMD) rate is a measure of interest rates in the Company’s largest financial guaranty insurance market, U.S. public finance. The MMD rate averaged 4.30% for 2025, higher than the 3.68% average rate in 2024 and higher than the 3.65% average rate for 2023. Meanwhile, the difference, or credit spread, between the 30-year BBB rated general obligation relative to the 30-year AAA MMD averaged 89 basis points (bps) in 2025, which is narrower compared to the 90 bps average for 2024 and compared to the 101 bps average for 2023. The Company believes that wider spreads could permit it to increase its premium rates on new business.

According to Freddie Mac, the 30-year fixed-rate mortgage rate averaged 6.15% for the week ending December 31, 2025, lower than the 30-year mortgage rate average of 6.85% from one year ago. The National Association of Realtors reported that there was a 1.4% increase in year-over-year existing-home sales from December 2024 to December 2025, and that the median existing-home sales price increased 0.4% from December 2024 ($403,700) to December 2025 ($405,400). Higher housing prices may benefit distressed RMBS the Company insures.

Key Business Strategies

The Company continually evaluates its business strategies and is currently pursuing key business strategies in four areas: (i) growth of its insurance and asset management businesses; (ii) loss mitigation; (iii) enhancement of investment returns through alternative investments; and (iv) capital management.

Insurance and Asset Management Growth

The Company seeks to grow its core financial guaranty insurance business through new business production in established sectors and jurisdictions and by entering into new markets, lines and classes of business. In addition, the Company seeks to leverage its core credit competencies by expanding its business into revenue streams independent of its financial guaranty insurance business, such as annuity reinsurance through its life and annuity reinsurance platform and its asset management business, with the objective of bolstering net income growth and predictability and generating high-return business opportunities.

Financial Guaranty Insurance Portfolio

The Company seeks to grow its financial guaranty insurance portfolio through new business production in each of its markets: public finance (including infrastructure) and structured finance. The Company believes high-profile defaults by municipal obligors, such as Puerto Rico, Detroit, Michigan and Stockton, California as well as events such as the COVID-19 pandemic have led to increased awareness of the value of bond insurance and stimulated demand for the product. The Company believes there will be continued demand for its insurance in this market because, for those exposures that the Company guarantees, it undertakes the tasks of credit selection, analysis, negotiation of terms, surveillance and, if necessary, loss mitigation. The Company believes that its insurance: (i) encourages retail investors, who typically have fewer resources than the Company for analyzing municipal bonds, to purchase such bonds; (ii) enables institutional investors to operate more efficiently; and (iii) allows smaller, less well-known issuers to gain market access on a more cost-effective basis.

The low interest rate environment and tight U.S. municipal credit spreads from when the financial crisis began in 2008 through early 2020 dampened demand for bond insurance compared with the levels before the financial crisis. After the onset of the COVID-19 pandemic in early 2020, credit spreads initially widened as a result of market concerns about the impact of the COVID-19 pandemic on some municipal credits, thereby improving demand for financial guaranty insurance even in a low interest rate environment, before narrowing again in 2022. The Company believes that, over time, wider credit spreads may improve demand for bond insurance.

In certain segments of the non-U.S. infrastructure and global structured finance markets, the Company believes its financial guaranty product is competitive with other financing options. In the infrastructure market, the Company’s financial guaranty can enhance the insured obligation’s rating, lower the cost of long-term funding and enhance the liquidity and transferability of debt obligations. Certain investors may receive advantageous capital requirement treatment with the addition of the Company’s financial guaranty. The Company considers its involvement in both infrastructure and structured finance transactions to be beneficial because such transactions diversify both the Company’s business opportunities and its risk profile beyond U.S. public finance. The timing of new business production in the infrastructure and structured finance sectors is influenced by typically long lead times and therefore production may vary from period to period.

(1) Source: The amounts in the table are those reported by London Stock Exchange Group. The table excludes private placements and Corporate-CUSIP transactions insured by Assured Guaranty, certain of which the Company also considers to be public finance business.

In addition, the Company considers opportunities to acquire financial guaranty portfolios, whether by acquiring financial guarantors that are no longer actively writing new business or their insured portfolios, generally through reinsurance or novations. These transactions enable the Company to improve its future earnings and deploy excess capital.

The Company seeks to expand its financial guaranty business geographically by entering new markets; in 2024, the Company opened new offices in Australia and Singapore. The Company has recently undertaken, and continues to undertake, several initiatives to broaden its insurance lines and classes of business, and improve the efficiency of its secondary market execution. For example, the Company has enhanced its structured finance new business production by developing fund finance into a flow business line. In addition, the Company is pursuing nonpayment insurance business strategies through internal and/or external growth opportunities.

Life and Annuity Reinsurance

On January 21, 2026, the Company purchased all of the outstanding share capital in Warwick Company (UK) Limited (which is the 100% indirect owner of Assured Life Reinsurance Ltd. (Assured Life Re, f/k/a Warwick Re Limited), for a purchase price of $158 million, subject to certain post-closing adjustments (Assured Life Re Acquisition). Assured Life Re is a Class E long-term (life) reinsurance company incorporated and registered in Bermuda and is rated BBB (Outlook Positive) (1/28/26) by Fitch Ratings, Inc. Assured Life Re focuses on annuity reinsurance including U.K. bulk purchase annuity (pension risk transfers) and U.S. multi-year guaranteed annuity transactions. The Company believes that the acquisition of the Assured Life Re platform will provide it with life and annuity business opportunities that complement its financial guaranty and asset management businesses, are consistent with its risk profile and benefit from its core competencies, including credit enhancement. The Assured Life Re Acquisition represents the Company’s first platform dedicated solely to the life and annuity reinsurance business.

See Part I, Item 1A. Risk Factors – Strategic Risks, captioned “The Assured Life Re Acquisition may negatively impact the Company, including how it is perceived by its investors, regulators, rating agencies or obligors it insures, as well as Assured Life Re’s business relationships,” “Entering the life and annuity reinsurance business may present integration risks and other risks specific to the life and annuity reinsurance business that could have a negative effect on the Company’s business, results of operations or financial condition,” “Strategic transactions may not result in the benefits anticipated” and “The Company makes assumptions when pricing its life and annuity reinsurance products relating to longevity, mortality, policy lapses, withdrawals, surrenders, investment returns and expenses, and significant deviations in experience could negatively affect the Company’s financial condition and results of operations.”

The Company continues to investigate additional opportunities in the life and annuity reinsurance business and in other businesses in line with its risk profile and that would benefit from its core competencies.

Asset Management

The Company participates in the asset management business through its ownership interest in Sound Point, and does not directly manage investments for third parties. The Company’s ownership interest in Sound Point furthers its growth strategy of participating in a diversifying fee-based earnings stream independent of the risk-based premiums generated by its financial guaranty business. In addition to its ownership interest in Sound Point, the Company also has in place a letter agreement (Letter Agreement) with Sound Point relating to the Company’s alternative investments portfolio which supports other key strategic initiatives. See “Enhancement of Investment Returns Through Alternative Investments” below. See Item 8. Financial Statements and Supplementary Data, Note 1. Business and Basis of Presentation and Note 7. Investments and Cash, for a description of the Company’s participation in the asset management business through its ownership interest in Sound Point.

Loss Mitigation

In an effort to avoid, reduce or recover losses and potential losses in its insurance portfolio, the Company employs a number of strategies.

In the public finance area, the Company believes its experience and the resources it is prepared to deploy, as well as its ability to provide bond insurance or other solutions, result in more favorable outcomes in distressed public finance situations than would be the case without its participation. This has been illustrated by the Company’s role in negotiating various agreements in connection with the restructuring of obligations of the Commonwealth of Puerto Rico and various obligations of its related authorities and public corporations, as well as Detroit, Michigan and Stockton, California. For public finance credits, the Company’s surveillance function monitors and proactively engages with the distressed credits to offer assistance aimed to improve operations and financial performance, including access to external consultants and other industry experts.

The Company also, from time to time and where appropriate, participates in litigation to enforce or defend its rights. For example, the Company initiated a number of legal actions to enforce its rights with respect to obligations of the Commonwealth of Puerto Rico and various obligations of its related authorities and public corporations. In addition, the Company successfully defended claims brought by Lehman Brothers International (Europe) (in administration) (LBIE) and prevailed in its counterclaim against LBIE; following the exhaustion of LBIE’s appeals, the Company recognized a realized gain on credit derivatives in the first quarter of 2025 of $103 million, which represents the full satisfaction of the judgment it was awarded and its claims for attorneys’ fees, expenses and interest in connection with this litigation. See, Item 8. Financial Statements and Supplementary Data, Note 17. Contingencies, Litigation, for additional information.

The Company may also purchase Loss Mitigation Securities in order to mitigate the economic effect of insured losses. The fair value of Loss Mitigation Securities as of December 31, 2025 (excluding the value of the Company’s insurance) was $140 million.

In July 2025, the Company’s largest BIG exposure in the investment portfolio, which was obtained as part of a loss mitigation strategy, with an aggregate carrying value of $408 million as of June 30, 2025, reached its final resolution after many years of negotiation and was paid down after liquidation of the trust assets. The Company received $459 million in connection with this resolution, including principal, accrued interest and other expected recoveries. This resolution did not have a significant effect on the consolidated statements of operations. Also, in connection with the sale in October 2025 of a commercially leased building that was part of a loss mitigation strategy for a troubled insured exposure, the Company recognized a pre-tax gain of $23 million in the fourth quarter of 2025, and realized a positive inception-to-date internal rate of return on the insured exposure.

The Company is, and for several years has been, working with the servicers of some of the U.S. RMBS transactions it insures to encourage the servicers to provide alternatives to distressed borrowers that will encourage them to continue making payments on their loans to help improve the performance of the related RMBS.

In some instances, the terms of the Company’s financial guaranty policies or the terms of certain workout orders and resolutions give it the option to pay principal on an accelerated basis on an obligation on which it has paid a claim, thereby reducing the amount of guaranteed interest due in the future. The Company has at times exercised this option, which uses cash but reduces projected future losses. The Company may also facilitate the issuance of refunding bonds, by either providing insurance on the refunding bonds or purchasing refunding bonds, or both. Refunding bonds may provide the issuer with payment relief.

Enhancement of Investment Returns Through Alternative Investments

The Company seeks to maintain an investment portfolio that supports the requirements of its insurance subsidiaries, strategic initiatives and liquidity needs, while maximizing the income it earns from such investments. In support of that goal, the Company aims to diversify the types of investments in its portfolio. The Company expects its relationship with Sound Point to enhance its alternative investment opportunities and the return on its investments. The Company has agreed to invest an aggregate amount of $1.5 billion in alternative investments, which includes $1 billion in Sound Point managed investments, subject to certain conditions precedent. See Item 8. Financial Statements and Supplementary Data, Note 7. Investments and Cash, for a description of the alternative investments agreement with Sound Point.

Capital Management

The Company’s capital management strategy is designed to efficiently allocate and utilize capital across the Assured Guaranty group in order to optimize outcomes for rating agency assessments, regulatory compliance and the Company’s own strategic initiatives and risk management requirements. The Company believes this disciplined approach to capital management supports the long-term stability and strength of Assured Guaranty, enabling it to advance its financial guaranty, asset management and annuity reinsurance businesses, and other corporate strategies. Assured Guaranty seeks to enhance financial flexibility and resiliency by proactively managing its capital and aligning resources with its business objectives and stakeholder interests.

From 2013 through February 25, 2026, the Company has repurchased 157 million common shares for $5.9 billion, representing 81% of the total shares outstanding at the beginning of the repurchase program in 2013. On August 6, 2025 and November 5, 2025, the Board authorized the repurchase of an additional $300 million and $100 million, respectively, of the Company’s common shares. As of February 25, 2026, the remaining amount the Company was authorized to purchase was $204 million of its common shares. Shares may be repurchased from time to time in the open market or in privately negotiated transactions. The timing, form and amount of the share repurchases under the program are at the discretion of management and will depend on a variety of factors, including funds available at the parent company, other potential uses for such funds, market conditions, the Company’s capital position, legal requirements and other factors. The repurchase program may be modified, extended or terminated by the Board at any time and it does not have an expiration date. See Item 8. Financial Statements and Supplementary Data, Note 18. Shareholders’ Equity, for additional information about the Company’s repurchases of its common shares.

____________________

(1) Excludes commissions.

As of December 31, 2025, the estimated accretive effect of the cumulative repurchases of common shares since the beginning of 2013 was approximately: $68.77 per share in shareholders’ equity attributable to AGL, $69.94 per share in adjusted operating shareholders’ equity and $116.18 per share in adjusted book value (ABV).

Over the last several years, the Company has received approval from its insurance regulators to redeem a portion of its insurance subsidiaries’ stock and pay extraordinary dividends from its insurance subsidiaries. Most recently, in the third quarter of 2025, after receiving approval from the MIA, AG redeemed $250 million of its common stock from AGMH in exchange for $213 million in cash and $37 million in alternative investments.

The Company considers the appropriate mix of debt and equity in its capital structure. The Company may in the future choose to issue new debt or redeem or purchase its existing debt. See “— Liquidity and Capital Resources — AGL and its U.S. Holding Companies.”

Executive Summary

The primary drivers of volatility in the Company’s net income include: loss and LAE, changes in fair value of certain alternative investments, credit derivatives, FG VIEs, CIVs, trading securities and CCS, as well as foreign exchange gains (losses), the level of refundings of insured obligations, the effects of any large transactions, settlements, commutations and loss mitigation strategies, among other factors. Changes in laws and regulations, among other factors, may also have a significant effect on reported net income or loss in a given reporting period.

Effective tax rate	17.9		%	19.7		%	(13.9)		%

Net income attributable to AGL in 2025 was higher compared with 2024 primarily due to the following:

•foreign exchange remeasurement gains of $96 million in 2025, compared with losses of $27 million in 2024,

•a gain on credit derivatives related to the resolution of the LBIE litigation of $103 million in 2025,

•higher other income due to a gain of $23 million recognized in connection with the sale in 2025 of a commercially leased building that was part of a loss mitigation strategy for a troubled insured exposure and $15 million associated with the workout and purchase of bonds issued by a U.K. regulated utility to which the Company has insured exposure and interest on late financial guaranty premiums,

•higher equity in earnings of investees in 2025, primarily generated by the Company’s investments in Sound Point, healthcare funds and legacy alternative investments, and

•fair value gains on committed capital securities in 2025, compared with losses in 2024.

These increases were partially offset by:

•loss and LAE in 2025 of $56 million, compared with a benefit of $26 million in 2024,

•net realized investment losses in 2025 primarily due to changes in the allowance for credit losses for alternative investments and Loss Mitigation Securities,

•lower fair value gains on trading securities in 2025, and

•lower net earned premiums in 2025, compared with 2024 due to lower refundings of financial guaranty insurance exposures.

The Company’s effective tax rate reflects the proportion of income recognized by each of the Company’s operating subsidiaries in the jurisdiction in which they are taxed, with U.S. subsidiaries and foreign subsidiaries that have made an election to be a U.S. taxpayer taxed at the U.S. marginal corporate income tax rate of 21%, U.K. subsidiaries taxed at the U.K. marginal corporate tax rate of 25% for periods starting April 1, 2023, and 19% for periods ending on or before March 31, 2023, and the French subsidiary taxed at the French marginal corporate tax rate of 25%, and AG Re and Cedar Personnel Ltd. taxed at the Bermuda marginal corporate tax rate of 15% starting January 1, 2025 and 0% for 2024 and 2023. See Part I, Item 1. Business – Regulation, and Part II, Item 8. Financial Statements and Supplementary Data, Note 13. Income Taxes.

Adjusted Operating Income

Adjusted operating income in 2025 was $445 million, compared with $389 million in 2024. The increase was primarily due to the gain related to the resolution of the LBIE litigation in 2025, higher equity in earnings of investees and the gain recognized in connection with the sale of a commercially leased building that was part of a loss mitigation strategy for a troubled insured exposure, offset in part by a higher loss expense in public finance sectors, lower fair value gains on the trading portfolio and lower earned premiums on refundings of financial guaranty insurance contracts in 2025. See “— Results of Operations — Reconciliation to GAAP” for the reconciliation of net income (loss) attributable to AGL to adjusted operating income (loss).

Book Value and ABV

Shareholders’ equity attributable to AGL as of December 31, 2025 increased compared with December 31, 2024, primarily due to net income and unrealized gains on the investment portfolio, partially offset by share repurchases and dividends. Adjusted operating shareholders’ equity and ABV decreased primarily due to share repurchases and dividends, partially offset by adjusted operating income and GWP. See “— Non-GAAP Financial Measures” below for the reconciliation of shareholders’ equity attributable to AGL to adjusted operating shareholders' equity and ABV.

On a per share basis, shareholders’ equity attributable to AGL, adjusted operating shareholders’ equity and ABV increased as of December 31, 2025 compared with December 31, 2024, due, in part, to the accretive effect of the share repurchase program. See “— Non-GAAP Financial Measures” for the reconciliation of shareholders’ equity attributable to AGL to adjusted operating shareholders' equity and ABV.

Other Matters

Inflation

By some key measures, consumer price inflation in the U.S. and the U.K. was higher in recent years than it has been in decades. In addition, government policies such as increased deficit spending or the imposition of tariffs on imported goods could increase inflationary pressures in the future. Consumer price inflation in the U.K. can impact the Company directly by increasing exposure for certain index-linked U.K. debt with par that accretes based on inflation, and also by increasing projected future installment premiums on the portion of such exposure that pays at least some of the premium on an installment basis over the term of the exposure. Consumer price inflation may also impact the Company indirectly to the extent it makes it more difficult for obligors to make their debt payments. See “— Overview — Economic Environment.”

Russia’s Invasion of Ukraine

Russia’s invasion of Ukraine has led to the imposition of economic sanctions by many western countries against Russia and certain Russian individuals, dislocation in global energy markets, massive refugee movements and payment default by certain Russian credits. The economic sanctions imposed by western governments, along with decisions by private companies regarding their presence in Russia, continue to reduce western economic ties to Russia and to reshape global

economic and political ties more generally, and the Company cannot predict all of the potential effects of the conflict on the world or the Company.

The Company’s surveillance and treasury functions have reviewed the Company’s insurance and investment portfolios, respectively, and have identified no material direct exposure to Ukraine or Russia. In fact, the Company’s direct insurance exposure to Eastern Europe generally is limited to $198 million in net par outstanding as of December 31, 2025, comprising of the sovereign debt of Poland. The Company rates this exposure investment grade.

Middle East Conflict

In light of events in the Middle East that began on October 7, 2023, the Company’s surveillance and treasury functions have reviewed the Company’s insurance and investment portfolios, respectively, for exposures to the Middle East. After review, the Company’s surveillance and treasury functions have identified no material direct exposure to such area. The Company’s direct insurance exposure to the Middle East is generally limited to funded and unfunded commitments to fund finance facilities. When fund finance facilities are launched, they obtain aggregate commitments across numerous investors in the fund. For certain facilities guaranteed by the Company, a small minority of investors are domiciled in the Middle East, which are generally sovereign wealth funds and pensions. Fund finance facilities guaranteed by the Company are always overcollateralized with uncalled capital commitments exceeding borrowings, and defaults of Middle East investors alone cannot cause a loss. Such facilities have additional mitigants, including the ability to call on performing investors to cover the obligations of defaulting investors and rights to sell defaulting positions to other investors at a discount. The Company rates all such insurance exposure investment grade.

January 2025 Los Angeles Wildfires

In January 2025, a series of destructive wildfires affected Los Angeles, California. The Company’s surveillance function has reviewed the Company’s insurance portfolio for exposures located within Los Angeles County and currently has not identified any material impact on the ability of such exposures to pay their obligations.

2026 U.S. Operation in Venezuela

On January 3, 2026, the U.S. executed an operation within Venezuela apprehending President Nicholas Maduro and his wife Cilia Flores who were taken to New York City and indicted in the U.S. Southern District Court of New York on several charges related to narcoterrorism. In light of this development, the Company’s surveillance and treasury functions have reviewed the Company’s insurance and investment portfolios, respectively, and have identified no direct exposure to Venezuela. The Company’s direct insurance exposure to South America is generally limited to $128 million in net par outstanding as of December 31, 2025, comprising of infrastructure finance in Colombia and Chile. The Company rates these exposures investment grade.

Results of Operations

Critical Accounting Estimates

The preparation of financial statements in accordance with GAAP requires the application of accounting policies that often involve a significant degree of judgment and require the Company to make estimates and assumptions, based on available information, that affect the amounts of assets, liabilities, revenues and expenses reported in the consolidated financial statements. Estimates are inherently subject to change and actual results could differ from those estimates, and the differences may be material to the consolidated financial statements.

Critical estimates and assumptions are periodically evaluated based on historical developments, market conditions, industry trends and other information that is reasonable under the circumstances. There can be no assurance that actual results will conform to estimates and assumptions and that reported results of operations will not be materially different in the future due to changes in these estimates and assumptions.

Listed below are the accounting estimates that the Company believes are most dependent on the application of judgment and assumptions. See Item 8. Financial Statements and Supplementary Data, Note 1. Business and Basis of Presentation, for the Company’s list of significant accounting policies which includes a reference to the applicable note where further details regarding the significant estimates and assumptions are provided. In addition, see Item 7A. Quantitative and Qualitative Disclosures About Market Risk, for further details regarding sensitivity analyses.

•Expected loss to be paid (recovered);

•Fair value of certain assets and liabilities, primarily:

•Investments (primarily alternative investments)

•Assets and liabilities of FG VIEs;

•Impairments of equity method investments and credit allowances for financial instruments; and

•Income tax assets and liabilities, including the recoverability of all deferred tax assets (liabilities) and in particular the Bermuda deferred tax asset recorded in 2023.

Net Earned Premiums and Credit Derivative Revenues

Premiums are earned over the contractual lives, or in the case of insured obligations backed by homogeneous pools of assets, the remaining expected lives, of financial guaranty insurance contracts. The Company periodically estimates remaining expected lives of its insured obligations backed by homogeneous pools of assets and makes prospective adjustments for such changes in expected lives. Scheduled net earned premiums decrease each year unless replaced by a higher amount of new business, or books of business acquired in business combinations. See Item 8. Financial Statements and Supplementary Data, Note 5. Contracts Accounted for as Insurance, Premiums, for additional information.

Net earned premiums due to accelerations are attributable to changes in the expected lives of insured obligations driven by: (i) refundings of insured obligations; or (ii) terminations of insured obligations either through negotiated agreements or the exercise of the Company’s contractual rights to make claim payments on an accelerated basis.

Refundings occur in the public finance market when municipalities and other public finance issuers pay down insured obligations prior to their originally scheduled maturities. Refundings tend to increase when issuers can refinance their debt obligations at lower rates than they are currently paying. The premiums associated with the insured obligations of municipalities and other public finance issuers are generally received upfront when the obligations are issued and insured. When issuers pay down insured obligations, the Company is no longer on risk for payment defaults, and therefore accelerates

the recognition of any remaining nonrefundable deferred premium revenue. The amortization of the Company’s outstanding book of business along with the previously high levels of refunding activity and the higher interest rate environment has led to a lower volume of refunding opportunities over the last several years.

Terminations are generally negotiated agreements with beneficiaries resulting in the extinguishment of the Company’s insurance obligation. Terminations have historically been more common in the structured finance sector, but may also occur in the public finance sector. While each termination may have different terms, they all result in the expiration of the Company’s insurance risk, the acceleration of the recognition of the associated deferred premium revenue and the reduction of any remaining premiums receivable.

Net earned premiums and credit derivative revenues increased in 2025 compared with 2024 primarily due to credit derivative revenues related to the resolution of the LBIE litigation (see Item 8. Financial Statements and Supplementary Data, Note 6. Contracts Accounted for as Credit Derivatives) and earnings on large transactions and supplemental premiums written in 2024, partially offset by lower financial guaranty insurance refundings and terminations. As of December 31, 2025, $3.6 billion of net deferred premium revenue remained to be earned over the life of the financial guaranty insurance contracts.

____________________

(1) PVP and Gross Par Written in the table above are based on “close date,” when the transaction settles. See “— Non-GAAP Financial Measures — PVP or Present Value of New Business Production.” PVP was discounted at 5.0% in both 2025 and 2024 and 4.0% in 2023.

GWP relates to insurance and reinsurance contracts for both financial guaranty and specialty business. Financial guaranty insurance and reinsurance GWP includes: (i) amounts collected upfront on new business written; (ii) the present value of future contractual or expected premiums on new financial guaranty business written (discounted at risk-free rates); and (iii) the effects of changes in the estimated premium or lives of certain transactions in the in-force book of business. Specialty business GWP is recorded as premiums are due. Credit derivatives are accounted for at fair value and therefore not included in GWP. PVP and gross par written include the present value of future gross revenues and exposure, respectively, associated with a financial guaranty written by the Company that, under GAAP, is accounted for under Accounting Standards Codification (ASC) 460, Guarantees.

The non-GAAP financial measure, PVP, includes upfront premiums and the present value of expected future installments on new business at the time of issuance, discounted at the approximate average pre-tax book yield of fixed-maturity securities purchased during the prior calendar year, for all contracts regardless of form or accounting model. See “— Non-GAAP Financial Measures” below.

U.S. public finance GWP and PVP include transactions closed in both the primary and secondary markets. Secondary market GWP and PVP each increased to $44 million in 2025 from $8 million in 2024. The Company’s par written in the secondary market represented 7.3% of U.S. public finance par written in 2025, compared with 2.5% in 2024.

U.S. public finance GWP and PVP in the primary market were higher in 2024 primarily due to a large transportation revenue transaction that was written in 2024. U.S. public finance GWP and PVP in 2025 included transportation revenue and infrastructure transactions. The Company’s primary par written represented 58% of the total U.S. primary municipal market insured par sold in both 2025 and in 2024, and the Company’s penetration of all municipal issuance was 4.4% in 2025 compared with 4.8% in 2024.

GWP for non-U.S. public finance in 2025 were negative primarily due to the early repayment of several U.K. sub-sovereign credits. GWP for non-U.S. public finance in 2024 included a change in the present value of future premiums on a large existing transaction, which was not a result of new business production and therefore excluded from PVP. Non-U.S. public finance PVP in 2025 was lower than PVP in 2024, primarily due to a lower volume of large transactions in 2025. Non-U.S. public finance PVP in 2025 included several primary infrastructure finance transactions in the European Union and secondary transactions in the U.K.

U.S. and non U.S. structured finance GWP and PVP in 2025 were primarily attributable to fund finance facilities, insurance securitizations, the upsize of a transaction providing protection on a core lending portfolio for an Australian bank, and consumer receivable transactions.

Business activity in the non-U.S. public finance and structured finance markets often has long lead times and therefore may vary from period to period.

Income from Investments

Net investment income is a function of the yield that the Company earns on available-for-sale fixed-maturity securities and short-term investments and the size of such portfolio. The investment yield on fixed-maturity securities is a function of market interest rates at the time of investment as well as the type, credit quality and maturity of the securities in this portfolio.

CVIs issued by Puerto Rico and received as part of the resolution of defaulting Puerto Rico exposures in 2022 are classified as trading with changes in fair value reported in “fair value gains (losses) on trading securities” in the consolidated statements of operations. The fair value of remaining CVIs as of December 31, 2025 and December 31, 2024 was $114 million and $123 million, respectively.

Equity method investments in the Insurance segment include certain alternative investments. The income (loss) on such investments is reported in “equity in earnings (losses) of investees” and typically represents the Company’s share of earnings of its investees. As part of stock redemptions that occurred in 2025 and 2024, certain alternative investments were distributed to AGMH, whose results are reported in the Corporate division.

____________________

(1) Foreign exchange gains on remeasurement of certain investments were $5 million for 2025 and $1 million for 2023.

Net investment income for 2025 increased compared to 2024, primarily due to investment income on CLO equity tranches in the available-for-sale portfolio. Certain CLO equity tranche investments were reclassified to the available-for-sale fixed-maturity portfolio in the fourth quarter of 2024, with interest income now reported in “net investment income,” and changes in fair value reported in “other comprehensive income.” The Company had previously held the CLO equity tranches in a Sound Point managed fund with changes in net asset value (NAV) reported in “equity in earnings (losses) of investees.” Short-term investment income declined as a result of lower short-term interest rates and lower short-term average investment balances. The overall pre-tax book yield of available-for-sale fixed-maturity securities and short-term investments was 4.76% as of December 31, 2025 and 4.57% as of December 31, 2024.

Equity in earnings (losses) of investees for 2025 decreased compared to 2024, primarily due to the reclassification of certain CLO equity tranches to the available-for-sale portfolio, as described above. In addition, equity in earnings (losses) of investees in 2024 included $18 million related to certain alternative investments reported in “private minority stakes in alternative asset manager” and “other” in the table above that AG transferred to AGMH as part of a stock redemption in 2024. These decreases were partially offset by an increase in the NAV of a asset based/specialty finance and private healthcare funds in 2025.

Other Income (Loss)

The increase in “other income (loss)” in 2025 compared with 2024 was primarily attributable to a gain of $23 million recognized in connection with the sale in 2025 of a commercially leased building that was part of a loss mitigation strategy for a troubled insured exposure and $15 million associated with the workout and purchase of bonds issued by a U.K. regulated utility to which the Company has insured exposure and interest on late financial guaranty premiums.

Economic Loss Development (Benefit)

The insured portfolio includes policies accounted for under several different accounting models depending on the characteristics of the contract and the Company’s control rights. For a discussion of methodologies and significant estimates for expected loss to be paid (recovered), see Item 8. Financial Statements and Supplementary Data, Note 4. Expected Loss to be

Paid (Recovered). For the GAAP accounting policies for measurement and recognition for each type of contract, see the notes listed below in Item 8. Financial Statements and Supplementary Data.

•Note 5 for contracts accounted for as insurance;

•Note 6 for contracts accounted for as credit derivatives;

•Note 8 for FG VIEs; and

•Note 9 for fair value methodologies for credit derivatives and FG VIEs’ assets and liabilities.

In order to efficiently evaluate and manage the economics of the entire insured portfolio, management compiles and analyzes expected loss information for all policies on a consistent basis. The discussion of losses that follows encompasses expected losses on all contracts in the insured portfolio regardless of accounting model, unless otherwise specified. Net expected loss to be paid (recovered) is equal to the present value of expected future cash outflows for loss and LAE payments, net of: (i) inflows for expected salvage, subrogation and other recoveries; (ii) excess spread on underlying collateral, as applicable; and (iii) amounts ceded to reinsurers. Assumptions used in the determination of the net expected loss to be paid (recovered) such as delinquency, severity, discount rates and expected time frames to recovery are consistent for each sector regardless of the accounting model used.

Current risk-free rates are used to discount expected losses at the end of each reporting period. Therefore, changes in such rates from period to period affect economic loss development and loss and LAE. However, the effect of changes in discount rates is not indicative of actual credit impairment or improvement. The weighted average discount rates used to discount expected losses (recoveries) were 3.92%, 4.38% and 4.09% as of December 31, 2025, 2024 and 2023, respectively.

The composition of economic loss development (benefit) by accounting model and by sector is presented in the tables that follow, and the drivers of economic loss development (benefit) are discussed below.

(1) Net of ceded paid losses, whether or not such amounts have been settled with reinsurers. Ceded paid losses are typically settled 45 days after the end of the reporting period. Such amounts are recorded as reinsurance recoverable on paid losses in “other assets.”

The effects of changes in the risk-free rates included in economic loss development (benefit) were losses of $7 million and $4 million in 2025 and 2024, respectively.

2025 Net Economic Loss Development

Public Finance: The economic loss development of $64 million for U.S. public finance exposures was primarily attributable to PREPA and certain healthcare exposures. The economic loss development of $33 million for non-U.S. public finance exposures was primarily attributable to certain U.K. student accommodation and U.K. regulated utility exposures.

U.S. RMBS: The economic benefit attributable to U.S. RMBS of $43 million was mainly attributable to a $33 million benefit from higher assumed and realized recoveries for secured second lien charged-off loans.

Other Structured Finance: The benefit attributable to other structured finance of $63 million was primarily attributable to recoveries related to the resolution of the LBIE litigation (see Item 8. Financial Statements and Supplementary Data, Note 6. Contracts Accounted for as Credit Derivatives).

See Item 8. Financial Statements and Supplementary Data, Note 4. Expected Loss to be Paid (Recovered), for additional information.

2024 Net Economic Loss Development

Public Finance: The economic benefit of $9 million for U.S. public finance exposures was primarily attributable to certain healthcare exposures, partially offset by higher expected loss adjustment expenses related to certain Puerto Rico exposures. The economic loss development of $81 million for non-U.S. public finance exposures was primarily attributable to certain U.K. regulated utilities and healthcare exposures.

U.S. RMBS: The net benefit attributable to U.S. RMBS of $75 million was mainly attributable to a $43 million benefit from higher assumed and realized recoveries for secured second lien charged-off loans and a $15 million benefit from higher assumed recoveries for first lien deferred principal balances.

Insurance Segment Loss Expense

The primary differences between net economic loss development and the amount reported as “loss and LAE (benefit)” in the consolidated statements of operations are that loss and LAE (benefit): (i) considers deferred premium revenue in the calculation of loss reserves for financial guaranty insurance contracts; (ii) eliminates loss and LAE related to FG VIEs; and (iii) does not include estimated losses or benefits on credit derivatives.

For financial guaranty insurance contracts, each transaction’s expected loss to be expensed is compared with the deferred premium revenue of that transaction. Expected loss to be expensed represents past or expected future net claim payments that have not yet been expensed. Such amounts will be expensed in future periods as deferred premium revenue amortizes into income on financial guaranty insurance policies. Expected loss to be expensed is the Company’s projection of incurred losses that will be recognized in future periods, excluding accretion of discount. When the expected loss to be expensed exceeds the deferred premium revenue, a loss is recognized in income for the amount of such excess. Therefore, the timing of loss recognition in income does not necessarily coincide with the timing of the actual credit impairment or improvement reported in net economic loss development. Transactions acquired in business combinations or seasoned portfolios assumed from legacy financial guaranty insurers (particularly BIG transactions) generally have large deferred premium revenue balances. To the extent that a BIG transaction has a large deferred premium revenue, the difference between economic development and loss and LAE may be significant.

While expected loss to be paid (recovered) is an important measure that provides the present value of amounts that the Company expects to pay or recover in future periods regardless of accounting model, expected loss to be expensed is important because it presents the Company’s projection of net expected losses that will be recognized in the consolidated statements of operations in future periods as deferred premium revenue amortizes into income for financial guaranty insurance policies. For additional information on the expected timing of net expected losses to be expensed, see Item 8. Financial Statements and Supplementary Data, Note 5. Contracts Accounted for as Insurance.

The amount of Insurance segment loss expense, which includes losses on policies regardless of form, is a function of the amount of economic loss development discussed above and the deferred premium revenue amortization in a given period, on a contract-by-contract basis. The following table presents the Insurance segment loss expense (benefit).

Employee Compensation and Benefit Expenses

The increase in employee compensation and benefit expenses to $182 million 2025 from $170 million in 2024 was primarily attributable to higher long-term compensation expenses, increase in headcount and other employee benefit costs.

Equity in earnings of investees in 2025 and 2024 relates to certain alternative investments, that AG transferred to AGMH as part of stock redemptions in 2024 and 2025. See “— Liquidity and Capital Resources—Insurance Subsidiaries—Stock Redemptions by Insurance Subsidiaries” below. The carrying value of these transferred investments as of December 31, 2025 was $184 million.

Corporate division employee compensation and benefits expenses and other operating expenses are an allocation of expenses based on time studies and represent the costs incurred and time spent on holding company activities, capital

management, corporate oversight and governance including the Board’s expenses, legal fees and other direct or allocated expense.

Other (Effect of Consolidating FG VIEs and CIVs)

The effect of consolidating FG VIEs and CIVs, intersegment eliminations and, prior to July 1, 2023, reclassifications of reimbursable fund expenses to revenue are presented in “other.” See Item 8. Financial Statements and Supplementary Data, Note 2. Segment Information.

As described in Item 8. Financial Statements and Supplementary Data, Note 8. Variable Interest Entities, the types of entities the Company consolidates when it is deemed to be the primary beneficiary primarily include: (i) FG VIEs; and (ii) CIVs. The Company eliminates the effects of intercompany transactions between its FG VIEs and CIVs and its insurance and asset management subsidiaries, as well as intercompany transactions between CIVs.

Consolidating FG VIEs (as opposed to accounting for the related insurance contracts in the Insurance segment), has a gross-up effect on the consolidated financial statements, and includes: (i) the establishment of the FG VIEs’ assets and liabilities and related changes in fair value on the consolidated financial statements; (ii) eliminating the premiums and losses/recoveries associated with the financial guaranty insurance contracts between the insurance subsidiaries and the FG VIEs; and (iii) eliminating the investment balances associated with the insurance subsidiaries’ purchases of the debt obligations of the FG VIEs.

Consolidating investment vehicles in which the Company invests (as opposed to accounting for them as equity method investments) has a significant effect on assets, liabilities and cash flows, and includes: (i) the establishment of the assets and liabilities of the CIVs, and related changes in fair value; (ii) eliminating the asset management fees earned by AssuredIM from the CIVs (prior to July 1, 2023); (iii) eliminating the equity method investments of the insurance subsidiaries, and related equity in earnings (losses) of investees; and (iv) establishing NCI for amounts not owned by the Company. The economic effect of AG’s ownership interests in CIVs is presented in the Insurance segment as “equity in earnings (losses) of investees,” while the effect of CIVs is presented as separate line items (“fair value gains (losses) on consolidated investment vehicles” and “noncontrolling interest”) on a consolidated basis.

The table below reflects the effect of consolidating FG VIEs and CIVs on the consolidated statements of operations. The amounts represent: (i) the revenues and expenses of the FG VIEs and the CIVs; and (ii) the consolidation adjustments and eliminations between consolidated FG VIEs or CIVs and the operating and investment subsidiaries.
