Three years ago, we embarked on a journey to build a specialty property and casualty insurance platform that included a distribution division and a specialty program insurance carrier. Our vision is to create the premier destination for MGA and program operators, and the quick ascent of our P&C businesses demonstrates that we have built a strong foundation to deliver on that goal. Key to our success is our people. In 2023 we hired top industry talent to help drive our growth and both Everspan and Cirrata exceeded their 2023 targets, generating over a half billion dollars of premium production, an 80% increase over 2022. That accomplishment is a testament to the hard work of the Everspan and Cirrata teams, whose achievements I will further expound on in the following pages. In 2023, we also added Kristi Matus and Michael Price as Directors, further bolstering the P&C expertise of our Board. While our future lies in the property and casualty insurance sector, we remain committed to maximizing the value of our legacy financial guarantee business. In 2023, we continued to improve the quality of the insured portfolio through various de-risking initiatives, which for the full year resulted in a reduction in net par outstanding by 14% and adversely classified credits by 26%. In addition, following the completion of an internal review process and analysis of the strategic options available for the legacy financial guarantee business, we appointed investment bank Moelis & Company to explore potential transactions with interested parties. As I noted in previous letters, Ambac remains committed to sustainability and responsible business practices. We continue to refine our policies to better reflect how these practices are embedded in our corporate culture, strategy, and decision-making. As part of our ongoing efforts to improve our disclosures, in 2023 we updated our Corporate Governance Guidelines and Code of Business Conduct and Ethics, and we published an updated and amended Corporate Social Responsibility (CSR) report in February 2024. We are excited about the direction Ambac is headed. As we look to the future, we are well positioned to leverage the strong growth generated in 2023, and we believe our specialty insurance platform is poised to deliver significant, incremental value for Ambac’s shareholders. 1 EVERSPAN SPECIALTY PROGRAM INSURANCE CARRIER In its second full year of operation, Everspan wrote $273 million of gross premium, achieving profitability in the second half of the year while establishing itself as a preferred partner of MGAs and reinsurers. Everspan exceeded its 2023 targets while maintaining its commitment to underwriting excellence and strong program oversight. Everspan had a very strong year, generating gross premium written of $273 million, an 87% increase over 2022 and a 9% increase over its 2023 target of $250 million. While we are pleased with those numbers, we are equally, if not more, focused on combined ratio, which factors both underwriting results and expense management, and is a more accurate gauge of an insurer’s performance and profitability. Everspan’s 100% combined ratio, reported in the fourth quarter, demonstrates a positive trend that we aim to improve in the coming quarters. Everspan’s fourth quarter results marked the fifth consecutive quarterly improvement for the business, which we believe has achieved the necessary scale to generate underwriting profitability. Everspan is now on a pathway to generating mid-teen ROEs at scale, over the insurance cycle. Portfolio diversification was also a key area of focus for Everspan in 2023, as the business sought to expand and diversify its MGA program partners. At year end, Everspan had 23 program partners, up from 14 a year ago. Equally important, its programs spanned a wide range of business classes, including commercial auto, excess liability, workers compensation and general liability, among others. Everspan’s book is now more balanced across risk classes, which should have the long-term benefit of more stable and predictable underwriting results. It is important to note that Everspan’s growth was achieved without sacrificing robust underwriting standards. Everspan accepted less than 5% of the program submissions it received, which is a testament to its careful selection methods. Its rigorous review process is underpinned by robust diligence and a “gross line” underwriting approach, meaning it applies the same evaluation criteria regardless of whether it retains 30% or very little risk. Uniform application of underwriting criteria helps keep Everspan’s interests aligned with the interests of its reinsurance partners. Everspan also aligns interests through its high-touch engagement model. With two full years of operation under its belt, it has established a comprehensive approach to program management, employing proactive risk management and oversight to achieve profitability for itself and its partners. We believe this approach is a strategic differentiator in the marketplace and a cornerstone to our achievements. $273 MILLION of GPW in 2023 Up 87% Combined Ratio 107% 23 MGA Programs 2023 GPW 61% E&S vs 39% Admitted Shareholders’ Equity $123 MILLION GROSS PREMIUM WRITTEN (GPW) & NUMBER OF PROGRAMS (in millions) $300 $225 $150 $75 $0 $273 $146 $13 2021 2022 2023 30 24 18 12 6 ( p r o g r a m # ) 300 225 150 75 0 Gross Premium Written # of Programs 2 CIRRATA INSURANCE DISTRIBUTION PLATFORM With a growing portfolio of distribution businesses, Cirrata has doubled its revenue in the last two years and beat its growth targets, achieving $231 million in placed premiums for 2023. It continues to attract premier underwriting teams looking to scale their businesses with Ambac’s support. Cirrata, like Everspan, exceeded its 2023 targets. It placed $231 million of premium in 2023, an increase of 70% over the prior year and a 15% increase over its 2023 target of $200 million. It also produced over $11 million of EBITDA. Cirrata’s revenue has doubled to $52 million in the last two years, while its EBITDA margin remains attractive at 22%. Cirrata’s growth has been fueled by both organic initiatives and the financial performance of recent acquisitions. It has acquired and onboarded three companies over the last 18 months and now operates four programs across various classes of business, including specialty commercial auto, professional liability, inland marine, employer stop loss, and affinity programs. After purchasing majority stakes in All Trans Risk Solutions and Capacity Marine Corporation at the end of 2022, we acquired a majority stake in Riverton Insurance Agency in August 2023. Xchange Benefits, our first MGU, rounds out the Cirrata portfolio. executive management and specialty lines experience, making him the ideal candidate to expand the Cirrata platform and build its profile in the specialty property and casualty insurance market. In 2023, Cirrata reached the size and scale to necessitate its own dedicated leadership team, and in May we appointed industry veteran Naveen Anand as President of Cirrata Group. Naveen has extensive We continue to see significant opportunities for growth at Cirrata, whether across our current businesses, via organic initiatives, or through additional M&A transactions and de novo incubations. $231 MILLION of Premium Placed Up 71% Over 2022 EBITDA Margin (1) of 22% Generating $11 MILLION (2) of EBITDA in 2023 REVENUE UP 68% in 2023 RIVERTON INSURANCE AGENCY CORP.

Since I joined Ambac seven years ago, we have de- risked and de-levered the insured portfolio by over $42 billion, materially improving our business risk profile and quality of our book value. During 2023 we continued our active de-risking efforts, which we expect will further enhance value for Ambac and its shareholders. Net insured par exposure for our legacy portfolio was $20 billion at December 31, 2023, down approximately 14% from $23 billion at year-end 2022. Our adversely classified credit exposure at year end was $3.5 billion, a reduction of 26% from the prior year end. Following a thorough process over the last year, the Wisconsin Office of the Commissioner of Insurance (OCI) has finalized its capital model and Stipulation and Order, providing a new regulatory framework for the legacy business. This new framework provides Ambac with clarity on capital requirements and pathways toward realization of value from the Legacy Financial Guarantee companies. Finally, in the fourth quarter we engaged Moelis & Company, along with other external advisors, to assess strategic options for our legacy business.

Words such as “estimate,” “project,” “plan,” “believe,” “anticipate,” “intend,” “planned,” “potential” and similar expressions, or future or conditional verbs such as “will,” “should,” “would,” “could,” and “may,” or the negative identify forward-looking of statements. We caution readers that these statements are not guarantees of future performance. Forward-looking statements are not historical facts but instead represent only our beliefs regarding future events, which may by their nature be inherently uncertain and some of which may be outside our control. These statements may relate to plans and objectives with respect to the future, among other things which may change. We are alerting you to the possibility that our actual results may differ, possibly materially, from the expected objectives or anticipated results that may be suggested, expressed or implied by these forward- looking statements. Important factors that could cause our results to differ, possibly materially, from those indicated in the forward-looking statements those discussed under “Risk Factors” in Part I, Item 1A in this Annual Report on Form 10-K. include, among others, Any or all of management’s forward-looking statements here or in other publications may turn out to be incorrect and are based on management’s current belief or opinions. Ambac Financial Group’s (“AFG”) and its subsidiaries’ (collectively, “Ambac” or the “Company”) actual results may vary materially, and there are no guarantees about the performance of Ambac’s securities. Among events, risks, uncertainties or factors that could cause actual results to differ materially are: (1) the high degree of volatility in the price of AFG’s common stock; (2) uncertainty concerning the Company’s ability to achieve value for holders of its securities, whether from Ambac Assurance Corporation (“AAC”) and its subsidiaries or from the specialty property and casualty insurance business, the insurance distribution business, or related businesses; (3) inadequacy of reserves established for losses and loss expenses and the possibility that changes in loss reserves may result in further volatility of earnings or financial results; (4) potential for rehabilitation proceedings or other regulatory intervention or restrictions against AAC; (5) credit risk throughout Ambac’s business, including but not limited to credit risk related to insured residential mortgage-backed securities, student loan and other asset securitizations, public finance obligations (including risks associated with Chapter 9 and other restructuring proceedings), issuers of securities in our investment portfolios, and exposures to reinsurers; (6) our inability to effectively reduce insured financial guarantee exposures or achieve recoveries or investment objectives; (7) AAC’s inability to generate the significant amount of cash needed to service its debt and financial obligations, and its inability to refinance its indebtedness;

("AFG"), headquartered in New York City, is a financial services holding company incorporated in the State of Delaware on April 29, 1991. References to “Ambac,” the “Company,” “we,” “our,” and “us” are to AFG and its subsidiaries, as the context requires. Ambac operates three principal businesses: • Legacy Financial Guarantee ("LFG") Insurance — Ambac's financial guarantee business includes the activities of Ambac Assurance Corporation ("AAC") and its wholly owned subsidiaries, including Ambac Assurance UK Limited (“Ambac UK”) and Ambac Financial Services LLC ("AFS"). Both AAC and Ambac UK are financial guarantee insurance companies that have been in run-off, having not underwritten any new business since 2008. AFS is AAC's legacy interest rate swap provider which is also currently being run-off. • Specialty Property and Casualty Insurance — Ambac's specialty property and casualty program business ("Specialty Property and Casualty Insurance") includes five admitted carriers and an excess and surplus lines (“E&S” or “nonadmitted”) carrier (collectively, “Everspan”). Everspan carriers have an AM Best rating of 'A-' (Excellent). • Insurance Distribution — Ambac's insurance distribution business includes managing general agents/underwriters (collectively "MGAs" or "MGA/Us") and insurance brokers operating as part of Cirrata Group. Beginning in 2022, the Company began reporting these three business operations as segments; see Note 3. Segment Information for further information. AFG, on a standalone basis, had $211 million in net assets (excluding its investment in subsidiaries) and net operating loss carry-forwards of $3,400 million ($1,760 million of which is allocated to AAC) at December 31, 2023. See Schedule II for more information on the holding company. Strategies to Enhance Shareholder Value is The Company's primary goal long-term shareholder value through the execution of targeted strategies for its (i) Specialty Property and Casualty Insurance and Insurance Distribution businesses and (ii) Legacy Financial Guarantee Insurance business. to maximize Specialty Property and Casualty Insurance and Insurance Distribution strategic priorities include: • Growing our Specialty Property and Casualty Insurance business to generate underwriting profits from a diversified liability risks portfolio of commercial and personal accessed primarily through program administrators. • Expanding our Insurance Distribution business based on deep domain knowledge in specialty and niche classes of risk which generate attractive margins at scale. This will be achieved through acquisitions, establishing new businesses “de-novo,” and organic growth and diversification supported by a centralized technology led shared services offering. • Making opportunistic investments that are strategic to both the Specialty Property and Casualty Insurance and Insurance Distribution businesses. Legacy Financial Guarantee Insurance strategic priorities include: • Actively managing, de-risking and mitigating insured portfolio risk, and pursuing recoveries of previously paid losses. • Improving operating efficiency and optimizing our asset and liability profile. • Exploring strategic options to further maximize value for AFG. DESCRIPTION OF THE BUSINESS Legacy Financial Guarantee Insurance: Financial guarantee insurance policies provide an unconditional and irrevocable guarantee which protects the holder of a debt obligation against non-payment when due of the principal and interest on the obligations guaranteed. Pursuant to such guarantees, AAC and Ambac UK make payments if the obligor responsible for making payments fails to do so when due. AAC and Ambac UK last wrote insurance policies in 2008 and have been in run-off ever since. Financial guarantee revenues consist mostly of premiums earned from run-off insurance contracts, net of reinsurance, and income on investments held in AAC's and Ambac UK's investment portfolios. Financial guarantee expenses consist of: (i) loss and commutation payments; (ii) loss adjustment expenses; (iii) interest expense on debt, (iv) operating expenses and (v) insurance intangible amortization. Ambac's Legacy Financial Guarantee Insurance business strategy is to increase the residual value of AAC and Ambac UK with the ultimate goal of monetizing such value through (i) dividends and capital distributions while managing their active run-off; (ii) one or more reinsurance transactions or other de- risking transactions that will accelerate or enhance the ability of AAC and/or Ambac UK to pay dividends and make capital distributions; (iii) the sale of all or portions of AAC and/or Ambac UK; or (iv) other strategic transactions to accelerate and/ or enhance the above-stated corporate strategy. Ambac and its advisors are actively discussing strategic options for its Legacy Financial Guarantee Insurance business with interested parties. While we anticipate that these discussions will be completed in 2024 there can be no assurance that we will ultimately complete any strategic initiative. AAC and Ambac UK have been reducing risk within their insured portfolios focusing on exposures to financially stressed insured exposures as well as large and concentrated exposures. Opportunities for remediating losses on poorly performing Ambac Financial Group, Inc 2 2023 Form 10-K insured exposures depend on a number of factors including market conditions, the structure of the underlying risk, the perception of AAC’s or Ambac UK’s creditworthiness, as well as counterparty specific factors. Their ability to remediate risk and commute policies may be limited by available liquidity. Additionally, AAC and Ambac UK are actively managing their to optimize capital regulatory allocation in complex insured portfolios that include long duration obligations. frameworks and seeking The execution of Ambac’s strategy to increase and monetize the value of its investment in AAC is subject to the restrictions set forth in the Settlement Agreement, dated as of June 7, 2010, as amended (the "Settlement Agreement"), by and among AAC, Ambac Credit Products LLC ("ACP"), AFG and certain counterparties to credit default swaps with ACP that were guaranteed by AAC, as well as the Stipulation and Order among the OCI, AFG and AAC that became effective on February 22, 2024 (the “Stipulation and Order”), replacing the Stipulation and Order that became effective on February 12, 2018, as amended (the “2018 Stipulation and Order”), each of which requires the Office of the Commissioner of Insurance for the State of Wisconsin ("OCI") and, under certain circumstances, holders of surplus notes, to approve certain actions taken by or in respect of AAC. In exercising its approval rights, OCI will act for the benefit of policyholders, and will not take into account the interests of AFG. • The Settlement Agreement limits certain activities of AAC and its subsidiaries, such as issuing indebtedness; engaging in mergers and similar transactions; disposing of assets; making restricted payments; creating or permitting liens; engaging in transactions with affiliates; modifying or creating tax sharing agreements; and taking certain actions with respect to surplus notes (among other restrictions and limitations). The Settlement Agreement includes certain allowances with respect to these activities and generally requires the approval of OCI and, in some cases, holders of surplus notes issued pursuant to the Settlement Agreement, for consents, waivers or amendments. as and surplus reserves • The Stipulation and Order requires AAC to maintain a level of regards contingency policyholders which provide reasonable security against contingencies affecting AAC’s financial position that are not otherwise fully covered by reserves or reinsurance; discount loss reserves in a manner approved by OCI; maintain OCI’s Runoff Capital Framework (as defined and described below) according to parameters specified by OCI; pay the costs of consultants and other experts retained by OCI; refrain from certain affiliate transactions and the payment of any dividend or other distribution without the prior non-disapproval of OCI; notify OCI of events that would or would be reasonably likely to cause a material adverse effect to AAC or its affiliates; obtain OCI’s non- disapproval to exercise certain control rights with respect to certain policies that were previously allocated to the Segregated Account of AAC; obtain OCI’s approval for non-ordinary course transactions involving consideration to be paid by AAC of $100 million or more; and obtain OCI’s approval of any changes to AAC’s investment policy or derivative use plan. The Stipulation and Order also requires AFG to use its best efforts to preserve the use of NOLs for the benefit of AAC and its subsidiaries. The Stipulation and Order differs from the 2018 Stipulation and Order in that the 2018 Stipulation and Order (i) did not refer to OCI’s Runoff Capital Framework; (ii) included certain affirmative covenants concerning books and records, and reporting of information or events, that were not included in the Stipulation and Order; and (iii) contained a more restrictive limitation on transactions with affiliates. The Stipulation and Order has no fixed term and may be terminated or modified only with the approval of OCI. OCI reserved the right to modify or terminate the Stipulation and Order in a manner consistent with the interests of policyholders, creditors and the public generally. The execution of Ambac’s strategy to increase the value of its investment in AAC may be affected by a new capital framework developed and implemented by OCI to assist OCI with making decisions related to capital management at AAC ("OCI's Runoff Capital Framework"). OCI’s Runoff Capital Framework applies risk-based and other adjustments to AAC’s assets and insured liabilities, as determined by OCI in its sole discretion. OCI’s Runoff Capital Framework allows AAC to understand the likely impact of various developments and actions now or in the future on AAC’s capital position thereunder. No changes in AAC’s current management of the business are required by OCI’s Runoff Capital Framework. AAC’s ability to use capital for potential future deleveraging transactions or distributions will require AAC to sustain an excess of risk-adjusted assets over risk-adjusted insured liabilities according to OCI’s Runoff Capital Framework, and to obtain OCI’s approval, and there can be no assurance that OCI will approve any such use of capital. The results of OCI’s Runoff Capital Framework are expected to vary over time based on changes in AAC’s financial position, insured portfolio developments, the impact of strategic actions taken by AAC, the impact of asset/liability management by AAC and, possibly, changes to the inputs and assumptions utilized by OCI. AAC has a significant amount of debt outstanding in the form of principal and accrued but unpaid interest on surplus notes. Surplus notes are treated as capital for regulatory purposes as the obligation to pay principal and interest on them is subordinated to the obligation to pay policyholder claims and such payments cannot be made without the explicit authorization of the OCI. legal and contractual AAC’s ability to pay dividends to AFG has also been significantly restricted by AAC’s financial condition and by regulatory, restrictions. Substantial uncertainty remains as to AAC's ability to pay dividends to AFG and the timing of any such dividends, which constrains AFG's liquidity. Refer to "Dividend Restrictions, Including Contractual Restrictions" below and to Note 8. Insurance Regulatory Restrictions to the Consolidated Financial Statements included in this Annual Report on Form 10-K, for more information on dividend payment restrictions. Interest rate derivative transactions were executed through AFS, a wholly-owned subsidiary of AAC. All remaining interest rate derivative positions, which are substantially economically hedged, relate to legacy financial guarantee customer swaps. Until the second quarter of 2023, interest rate derivatives were also used to partially hedge interest rate risk in the financial Ambac Financial Group, Inc 3 2023 Form 10-K guarantee insurance and investment portfolios. AFS continues to be required to post collateral in excess of the market value of certain interest rate derivatives when they are in a mark-to- market loss position. While not anticipated, early termination of AFS’s derivatives could result in losses. AFS has borrowed cash and securities from AAC to help support its collateral and margin posting requirements and other cash needs. Ambac manages a variety of risks inherent in its businesses, including credit, market, liquidity, operational and legal. These risks are identified, measured, and monitored through a variety of control mechanisms, which are in place at different levels throughout the organization. See “Quantitative and Qualitative Disclosures About Market Risk” included in Part II, Item 7A in this Annual Report on Form 10-K for further information. Risk Management Ambac’s financial guarantee insurance policies expose the Company to the direct credit risk of the assets and/or obligor supporting the guaranteed obligation. In addition, insured transactions expose Ambac to indirect risks that may increase our overall risk, such as credit risk separate from, but correlated with, our direct credit risk; market; model; economic, including the risk of economic recession; natural disaster; pandemic and mortality or other non-credit type risks. Please refer to Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Financial Guarantees in Force” section below for details on the financial guarantee insured portfolio. The Risk Management Group ("RMG") is primarily responsible for the management of the insured financial guarantee portfolio, including Surveillance and Risk Remediation (including through the pursuit of recoveries in respect of paid claims and commutations of policies). Our ability to execute certain risk management activities may be limited by the restrictions set forth in the Settlement Agreement and the Stipulation and Order, among other constraints. To the extent OCI's approval is required in connection with risk management activities, OCI's decisions may be guided by OCI's Runoff Capital Framework. See Note 1. Background and Business Description to the Consolidated Financial Statements included in this Annual Report on Form 10-K for further information. transaction or bond type’s review period and surveillance requirements. Please refer to Note 2. Basis of Presentation and Significant Accounting Policies to the Consolidated Financial Statements included in this Annual Report on Form 10-K for further discussion of the various credit classifications utilized by Ambac. surveillance activities The insured portfolio contains exposures that are correlated and/ or concentrated. RMG's include identifying these types of exposures and identifying the risks that would or could trigger credit deterioration across these related exposures. This is the case with student loans and residential mortgage-backed securities ("RMBS"), for example, which have several correlations including those associated with consumer lending, unemployment, interest rates and home prices. In the future, Ambac’s portfolio may be subject to similar credit deterioration arising from concentrated and/or correlated risks. Examples of other such risks that could impact our portfolio, and that our surveillance is designed to monitor include the impact of potential municipal bankruptcy contagion, the impact of large-scale domestic military spending or troop level cutbacks on our privatized military housing portfolio and event risk such as pandemics (e.g., COVID-19), natural disasters or other regional stresses. Most such risks cannot be predicted and may materialize unexpectedly or develop rapidly. Although our surveillance allows us to connect the event and stress to the related exposures and assign an adverse credit classification and estimate losses across the affected credits, when necessary, we may not have adequate resources or contractual rights and remedies to mitigate loss arising from such risks. Watchlist and Adversely Classified Credits Watch list and adversely classified credits are tracked closely and are discussed as part of scheduled RMG credit meetings. A summary of developments regarding adversely classified credits and credit trends is also provided to AFG’s, AAC’s and Ambac UK's Boards of Directors no less than quarterly. Ambac assigns internal credit ratings to individual exposures as part of the Surveillance process. These internal credit ratings, which represent Ambac’s independent judgments, are based upon underlying credit parameters consistent with the exposure type. Surveillance Risk Remediation Surveillance is focused on the early identification of potential stress and/or credit deterioration and the related analysis of credit exposures insured portfolio. Additionally, Surveillance evaluates the impact of changes in the economic, regulatory or political environment on the insured portfolio. the in Analysts perform periodic credit reviews of insured exposures according to a schedule based on the risk profile of the guaranteed obligations or as necessitated by specific credit events or other macro-economic variables. Surveillance strategies have been developed for each bond type with review periods and scope of review based upon each bond type’s risk profile. The risk profile is assessed regularly in response to our own experience and judgments or external factors such as the economic environment and industry trends. The focus of a credit review is to assess performance, identify credit trends and recommend credit classifications, ratings and changes to a Risk Remediation activities are centered on exposure reduction and loss mitigation related to the insured portfolio. In particular, the focus is on reducing exposure to credits that have negative developing trends, the potential for future adverse development or are already adversely classified by, among other things, exercising rights and remedies, which may help to mitigate losses in the event of further deterioration or events of default, or, as available, working with an issuer to refinance, defease or otherwise retire debt. Loss mitigation focuses on the execution of commutation and related claims reduction or workout strategies for policies with potential future claims. For certain adversely classified, survey list and watch list credits (as described in Note 2. Basis of Presentation and Significant Accounting Policies the Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K), risk remediation or loss to Ambac Financial Group, Inc 4 2023 Form 10-K mitigation plans are developed and implemented that may include actions such as working with the issuer, trustee, bond counsel, servicer and other interested parties in an attempt to remediate the problem and minimize Ambac’s exposure to potential loss. Other actions could include working with bond holders and other economic stakeholders to negotiate, structure and execute solutions, such as commutations. In addition, reinsurance is used as a remediation tool to reduce exposure to certain targeted policies and large concentrations. In some cases, the RMG will engage restructuring or workout experts, attorneys and/or other consultants with appropriate expertise in the targeted loss mitigation area to assist in examining the underlying contracts or collateral, providing industry specific advice and/or executing strategies. Control Rights In certain domestic and international structured finance transactions, structured public finance transactions, public- private partnerships and other transactions, AAC and Ambac UK may be the control party as a result of insuring a transaction’s senior class or tranche of debt obligations. The control party may direct specified parties, usually the trustee, to take or not take certain actions following contractual defaults or trigger events. Control rights and the scope of direction and remedies vary considerably among our insured transactions. Because AAC and Ambac UK are party to and/or have certain rights in documents supporting transactions in the insured portfolio, they may receive requests for amendments, consents and waivers (“ACW”). Decisions to approve or reject ACWs are made by AAC’s and Ambac UK’s risk management groups based upon certain credit factors, such as the issuer’s ability to repay the bonds and the bond’s security features and structure. P&C Industry Overview We operate within the $875 billion U.S. P&C insurance market with a particular focus on the commercial MGA/U program market both on an Admitted and Excess & Surplus Lines ("E&S") basis. Admitted and E&S Insurance Insurance carriers sell commercial P&C products in the United States through one of two markets: the Admitted market and the E&S market. The Admitted insurance market, which has highly regulated rates and policy forms, is more consistent in price and coverage. In the E&S market, there is increased flexibility in pricing, terms, and conditions in response to evolving market dynamics, and E&S carriers can tailor insurance products to facilitate coverage that would not otherwise be attainable. This unique flexibility lends itself to providing solutions for unique risks, which has driven meaningful growth within the E&S market over the last decade exceeding the growth rate of the Admitted market. According to data from AM Best, the E&S market generated approximately $99 billion of direct written premium in 2022 an increase of 19.2% over the prior year and and represents over 11% of the industry direct premium volume. The E&S market is more heavily focused in commercial lines and accounted for over 21% of total commercial direct written premium for the first time in 2022. For the period of 2012 through 2022 the E&S sector had a compound annual growth rate of 11% compared to 5% for the overall U.S. P&C sector. indicated below: Everspan Everspan presently has five admitted carriers, which are wholly- owned except as Insurance Company; Greenwood Insurance Company; Consolidated National Insurance Company; Consolidated Specialty Insurance Company; and Providence Washington Insurance Company (90.1% owned). Everspan Indemnity Insurance Company ("Everspan Indemnity"), an E&S carrier, which is eligible to write business in all U.S. states and territories, is also part of Everspan. MGA/U Program Market It is estimated that U.S. MGA/Us generate between $70 to $100 billion of direct premiums in 2023. We believe there are significant advantages to the MGA/U business model when it comes to capturing the opportunity in the E&S market and propelling profitable growth. MGA/Us are specialized types of insurance agents or brokers that are vested with underwriting insurer, administering programs and authority negotiating contracts on their behalf. This is a particularly useful vehicle for P&C insurers as MGA/Us tend to participate in the E&S market where specialized expertise is needed to underwrite policies. Additionally, MGA/Us are cost effective means for an insurer or reinsurer to access or grow a particular class of business they find attractive given the MGA/U already possesses product expertise and distribution capabilities. from an According to data from AM Best, the MGA/U sector is one of fastest growing segments of the U.S. P&C insurance market with 2022 direct premium written of $68 billion, an increase of 14% over the prior year, and loss ratios consistently lower than the P&C sector overall. In 2022, AM Best identified 654 MGAs in the U.S. market with likely several hundred additional MGAs not counted in that group as their premium production falls below the filing threshold. We believe the growth in the MGA/U and program space is likely to continue as the industry continues its move towards increased specialization. Specialty Property and Casualty Insurance Everspan’s strategy is to generate sustainable and profitable, long-term specialty property and casualty program business with a focus on diverse classes of commercial and personal liability risks across an expanding roster of MGA/U partners. As a specialty property and casualty program group. Everspan may retain a percentage of the business it underwrites. Everspan's management team has significant years of experience in the program insurance and reinsurance sectors and has long- standing and broad relationships with MGA/Us, reinsurers, third-party claims administrators brokers, producers and ("TPAs"). Everspan through program administrators and managing general agents, reinsurers, brokers, producers and others. Subject to Everspan's operational oversight, Everspan engages these third parties to market and administer policies and handle claims within defined authorities on Everspan's behalf. sources business Everspan is focused on generating strong underwriting results and stable fee income as part of its specialty program business model. Ambac Financial Group, Inc 5 2023 Form 10-K For the year ended December 31, 2023, Everspan generated $273 million of gross written premium, of which Everspan retained approximately 29%, including assumed written premiums. Everspan retained approximately 17% of its direct written premiums, with the balance primarily ceded to quota share reinsurers. Everspan may retain up to 30% of risk on each direct program and will reinsure the remainder to reinsurers and other providers of risk capital. These reinsurers may be domestic and foreign reinsurers and institutional risk investors (capacity providers). While underwriting direct business produced by MGA/Us is Everspan's primary means of distribution, Everspan also selectively assumes reinsurance to further its goal of writing a diversified book of specialty P&C business while efficiently managing its exposure limits. For example, the Company would evaluate, and may write certain lines, including those with catastrophe risk or Workers’ Compensation on an assumed basis. Everspan may participate as a reinsurer on up to 30% of a program, which is in line with its strategy to retain up to 30% of risk per program. Participation as a reinsurer will affect the retention ratio as Everspan's portion of assumed premiums is reflected fully in both Gross and Net Written Premiums. The following table sets forth gross written premiums (direct and assumed) by line of business for the years ended December 31, 2023 and 2022: ($ in millions) Year Ended December 31, 2023 2022 of credit issued by or trust accounts in the custody of NAIC- qualified financial institutions, to secure the reinsured risks. The following graph shows our reinsurance carriers' AM Best rating based on share of ceded premium for the year ended December 31, 2023: A 14% A- 1% NR 16% A+ 16% A++ 53% (1) NR represents reinsurance carriers not rated by AM Best. Generally, under the terms of reinsurance contracts with such carriers the reinsurer is required to post collateral to Everspan. See Note 7.

Generally, contracts are specific to a program and are renewed annually, at which time they are subject to renegotiation. The key contractual provisions include, but are not limited to, those relating to the scope of business reinsured, ceding commissions, required reports to reinsurers, dispute resolution, any required collateral, and Everspan's termination rights when, among other triggers, a reinsurer defaults (such as by failing to collateralize its obligations when required) or its financial strength falls below an agreed level. Everspan’s ceded reinsurance contracts do not legally discharge Everspan from its primary liability for the full amount of the policies, and Everspan will be required to pay the loss and bear collection risk if a reinsurer fails to meet its obligations under the reinsurance agreement. Everspan mitigates this credit risk by selecting well capitalized, highly rated, authorized capacity providers, or requiring that the capacity provider post collateral, typically in the form of letters Specialty Property and Casualty Insurance is a competitive industry. Everspan believes that it can successfully operate in this industry in part based upon the following competitive strengths. • Experience — Everspan has an experienced leadership team across underwriting, pricing, claims, and business development with an average tenure of over 30 years in the insurance industry. • Underwriting Focused Strategy — Everspan is driven by underwriting performance, which is achieved via comprehensive diligence and monitoring of MGA/U partners from our in-house pricing actuaries, claims executives, and program managers. This underwriting focus also aides in achieving and maintaining support from reinsurance partners. • Risk Appetite — Everspan may retain up to 30% of the risk it underwrites. This meaningful participation serves to align interests with our reinsurers. • Commitment to Program Distribution — Everspan does not have any direct distribution capability as is committed to the program market distributed through MGA/Us. As a result, Everspan does not have channel conflicts which would compete with programs partners in underwriting business. it • Nimble Platform — A simplified organizational structure which allows Everspan to be efficient and quick in responding to the needs of program partners as well as finding customized solutions. We believe this provides a Ambac Financial Group, Inc 6 2023 Form 10-K competitive advantage to the more traditional competitors in the market. • Aligned Ownership — Everspan has a stable ownership structure which is equally focused on long-term value creation based on strong underwriting performance. This alignment of interest and strategic vision allows Everspan to leverage resources across Ambac and access capital for future initiatives. Competition: Everspan faces competition from program business market participants such as Accelerant, Benchmark, Clear Blue, Core Specialty, Falls Lake, Fortegra, Obsidian, Spinnaker, State National, Transverse, and Trisura. Most of these entities have both admitted and E&S carriers. Competition may take the form of lower program fees, broader coverages, greater product flexibility, higher coverage limits, greater customer service or higher financial strength ratings by independent rating agencies. Few barriers exist to prevent existing insurers from entering target markets within the property and casualty industry. Market the degree of conditions and capital capacity competition at any point in time. influence During periods of excess underwriting capacity, as defined by the availability of capital, competition can result in lower pricing and less favorable policy terms and conditions for insurers. During periods of reduced underwriting capacity, pricing and policy terms and conditions are generally more favorable for insurers. Historically, the performance of the property and casualty insurance industry has tended to fluctuate in cyclical periods of price competition and excess underwriting capacity, followed by periods of high premium rates and shortages of underwriting capacity. At any given time, Everspan's portfolio of insurance products could experience varying combinations of these characteristics. This cyclical market pattern can be more pronounced in the specialty insurance and reinsurance markets in which Everspan competes than in the standard insurance market. For the last several years the property and casualty industry has been in a period of high premium rates with a shortage of underwriting capacity. While not anticipated to end in the short-term, this cyclical period will eventually end, perhaps unexpectedly. The end of this favorable cycle could have negative consequences for Everspan's growth and profitability prospects. Business Acquisition and Program Partner Selection: focus on generating With our long-term underwriting profitability, we are selective in adding new program partners. We look for program partners that share our vision of underwriting performance and return expectations and consequently are selective about with whom we partner. As of December 31, 2023, we have 23 programs with 19 MGA/Us. In 2023 we reviewed over 180 submissions and agreed to contract 11 new programs with eight new MGA/Us and two MGA/Us with an existing relationship, while renewing or extending twelve programs with eleven incumbent MGA/Us. Included in 2023 new programs are two executed via assumed reinsurance. As noted above, most of Everspan’s programs are sourced either from MGA/Us or through other third parties, such as reinsurance brokers, that are seeking to provide customized insurance solutions that require a carrier with a high rating from AM Best. Everspan works with MGA/Us that leverage both data and technology to streamline or improve the underwriting process. Everspan may also source programs as a reinsurer. Accessing programs as a reinsurer provides Everspan the ability to diversify its risk profile, efficiently manage its exposure limits and underwrite programs in a cost efficient manner, amongst other benefits. For each new opportunity that Everspan chooses to evaluate, an initial evaluation of the MGA/U is conducted, including an assessment of its underwriting approach, philosophy, size, quality of management, past performance, future performance targets and, above all, compatibility with Everspan’s operating model, risk appetite, and existing book of business. Everspan conducts substantial due diligence on all program partners led by the Underwriting Risk Committee which is chaired by Everspan’s Chief Underwriting Officer. As part of the diligence process, Everspan works closely with potential MGA/Us to design program underwriting guidelines, ongoing reporting and auditing requirements. Everspan also typically requires the producing partner to retain underwriting risk or otherwise align incentives with program underwriting performance. Additionally, as part of the diligence process for each program, Everspan will perform a review of the claims management function, typically performed by a TPA, which in some cases are managed by the MGA/U or producing partner. Diligence focuses on claims handling and litigation management, compliance, finance, governance, staff and vendor management, data and IT. After due diligence is completed and acceptable reinsurers are identified, each program is presented to the Underwriting Risk final approval. The Underwriting Risk Committee Committee will consider recommendations made by the credit subcommittee regarding the financial strength of the MGA/Us and/or reinsurers. for Ongoing Monitoring: For active programs, Everspan authorizes MGA/Us to underwrite and bind coverages in accordance with approved underwriting guidelines and delegates authority to the TPA for claims adjustment and payment. Everspan closely monitors each MGA/U and TPA’s adherence to the agreed upon underwriting and claims guidelines. Everspan will conduct periodic reviews of loss experience, rate levels, reserves and the overall financial health of the MGA/U and TPA and hold monthly underwriting meetings with both the MGA/U and TPA. Underwriting and claims data is provided by the MGA/Us and TPAs monthly. Additionally, Everspan conducts underwriting, claims and accounting audits, generally on-site, at least once a year for MGA/U and TPA partners which administer a material amount of Everspan's business. Everspan determines whether it will continue to participate on a program no less than annually, generally at the anniversary date of the program. The renewal process entails an assessment, with Underwriting Risk operating of Committee performance, profitability, and available reinsurance capacity. Everspan maintains the right to terminate relationships with its MGA/Us and TPAs. Reasons to terminate a relationship include participation, program's the Ambac Financial Group, Inc 7 2023 Form 10-K an inability to produce targeted underwriting results, writing exposures outside of agreed upon risk tolerances, delinquency in meeting reporting requirements, a change of strategic direction, or failure to meet collateral or other commitments to Everspan. Ratings: Everspan carriers have an AM Best financial strength ratings ("FSR") of 'A-' (Excellent) and Financial Strength Category of Class VIII. Risk is shared among the Everspan carriers via a reinsurance agreement and an intercompany pooling agreement (the "Everspan Pool"). We view this rating and financial size category as a competitive advantage in the marketplace. Ratings are an important factor in assessing Everspan’s competitive position, operation capabilities and risk management in the insurance industry. Insurance Distribution its existing Ambac’s Insurance Distribution business, Cirrata Group ("Cirrata"), has a strategy to build a diversified portfolio of MGA/Us and other insurance distributors covering various P&C Insurance to grow products. Ambac plans Distribution business using several strategies, including (i) organic growth, (ii) additional acquisitions and/or partnerships, and (iii) hiring experienced underwriting teams to incubate start- up MGA/Us. Key criteria include a track record of profitability and a seasoned management team. Insurance underwritten through Ambac's MGA/Us may utilize Everspan as an insurance carrier, but are not be required to do so, depending on strategic and operational considerations. The following table sets forth Cirrata's premiums placed by line of business: ($ in millions) Year ended December 31, Employee stop loss Limited & short-term medical Commercial auto Marine Professional liability Other Premiums placed 2023 2022 $ 76 $ 54 62 19 12 6 231 $ $ 72 48 11 1 — 4 135 Cirrata's portfolio at December 31, 2023, includes the following entities: Xchange — Ambac owns an 80% controlling interest in Xchange Benefits, LLC ("Xchange"). Xchange operates through specialty producers in accident and health ("A&H") sectors across the U.S. which are typically not targeted by large direct writers and to whom Xchange can provide customized offerings. Xchange conducts business through approximately ten insurance carriers and dozens of agents and other distributors. Xchange's main products for which it is delegated underwriting authority by insurance carriers include: • Employer Stop Loss ("ESL") — provides protection for self-insured employers by serving as a reimbursement mechanism for catastrophic claims, both specific and in aggregate exceeding pre-determined levels. • Limited Benefit Medical ("LM") — designed as a supplement to traditional Affordable Care Act medical programs and sold primarily through affinity groups, providing a variety of medically related benefits such as inpatient hospital stays, diagnostic services or physician visits. • Short-term Medical ("STM") — sold primarily through affinity groups, providing non Affordable Care Act comprehensive medical coverage for short durations (i.e. less than one year). • Xchange Re ("MGA/U") / Distribution Re ("Captive") — in January 2023, Xchange launched two new growth initiatives; Xchange Re an A&H reinsurance MGA/U and Distribution Re a protected cell captive insurance company domiciled in Tennessee which will mainly insure high deductible medical stop loss plans. Xchange does not intend to accept or retain any risk from Distribution Re. All Trans — Effective November 1, 2022, Ambac acquired an 85% controlling interest in All Trans Risk Solutions, LLC ("All All Trans is a full service managing general Trans"). underwriter with delegated underwriting in commercial automobile insurance for specific "for-hire" auto classes; principally private school bus operators. In 2024, AllTrans launched a new program primarily focussed on charter buses. All Trans' track record of performance has allowed the company to maintain a consistent panel of insurance carriers and client relationships, several of which go back over 25 years. authority Capacity Marine — Effective November 1, 2022, Ambac acquired an 80% controlling interest in Capacity Marine Corporation ("Capacity Marine"). Capacity Marine is a wholesale and retail brokerage and reinsurance intermediary specializing in more sophisticated marine and international risk in expsoures such as ports, terminals, and stevedores. interest Riverton — Effective August 1, 2023, Ambac acquired an 80% controlling in Riverton Insurance Agency, Corp. ("Riverton"). Riverton offers professional liability insurance programs licensed architects, engineers, construction managers and real estate professionals. Riverton's retail agency places professional liability for real estate agents with various markets. to In addition to existing MGA/Us and acquisitions, de novo MGA/U formations will be a core element of the Insurance Distribution segment's growth strategy. Cirrata's businesses are compensated for their services primarily by commissions paid by insurance carriers for underwriting, structuring and/or administering polices and, in some cases for managing claims under agency agreements. Commission revenues are usually based on a percentage of the premiums placed. The businesses are also eligible to receive profit sharing contingent commissions on certain programs based on the underwriting results of the policies they write, which may cause some variability recognition. Commission revenues experience seasonality during the year, primarily from Xchange whose ESL programs are mostly underwritten in January and July resulting in revenue and earnings concentrations in the first and third quarters each calendar year. Given the recent acquisitions and potential de revenue and earnings in Ambac Financial Group, Inc 8 2023 Form 10-K novo launches, this seasonality is expected to become more muted over time. Expenses at Cirrata include commissions the businesses pay to their independent agents/producers, compensation for their management and staff and intangible asset amortization from acquisitions. Commission expenses are a variable cost as we pay a percentage of premiums written to the agents/producers. Insurance Distribution generated gross commission revenue of $51 million and $31 million during the years ended December 31, 2023 and 2022, respectively and net commission revenue (gross commissions less commission expenses) of $22 million and $13 million, respectively. Commission revenue and expense growth will be driven by the businesses' continued expansion and diversification of its products across regions, products, and carriers. Competitive Strengths: • Deep specialty domain knowledge — Our Insurance Distribution businesses are anchored by a deep specialty domain knowledge in their respective classes of business. This knowledge is key to generating the underwriting results necessary long-standing carrier relationships. to maintain • Long standing carrier relationships — Our MGA/Us strive towards long and durable carrier relationships supported by a focus on underwriting profitability. P&C insurance is a cyclical industry with opportunistic players entering and exiting the business. We believe that growing multi-year carrier relationships are evidence of the value created by our MGA/U, a value which we believe should sustain through routine market cycles. • Strong distribution relationships — Distribution relationships provide value in several ways. First, carrier partners are looking for both underwriting expertise and distribution access when working with MGA/Us. In addition the quality of distribution relationships helps in allowing our MGA/Us access to higher quality risks from the wholesale and retail agents which we believe over time will help produce better underwriting results.. Competition: The MGA/U insurance sector is highly competitive, and firms actively compete with Cirrata's businesses for customers and insurance carrier capacity. • The ESL market is increasing in size as large companies continue to transition from fully insured to self-funded. As the market size increases, capital is flowing into the market, making prices and margins competitive. Blue Cross, UnitedHealth, CIGNA and Aetna are the largest writers. Competition also comes from large direct writers such as Tokio Marine, HCC and Sun Life as well as smaller carriers such as Gerber Life writing through other MGA/U firms. • For LM and STM, overall market conditions remain stable. the The overall market unemployed and others seek options for individual insurance. Competition for Xchange's business comes from large as entrepreneurs, is both direct carriers and other intermediaries and, depending on the product, may include Blue Cross, UnitedHealth, CIGNA, Aetna, Tokio Marine, Houston Casualty Company, Sun Life, United Health, Axis, Chubb, and National General. • In the commercial auto "for-hire" classes All Trans competes with a variety of carriers both national and regional. Overall, carriers have been cutting back on their participation and or capacity in commercial auto due to poor underwriting performance, which has benefited All Trans which is focused on narrower niche classes of risk within the larger commercial auto sector. This competitive environment has allowed All Trans to price properly and provide strong underwriting results. All Trans competes with Lancer insurance, National Interstate, Utica, RLI and various other MGA/U companies. • In professional liability markets, overall market conditions remain stable. Riverton competes with RLI, CNA, Hartford and various other MGA/U companies. ENTERPRISE RISK MANAGEMENT The Company's policies and procedures relating to risk assessment and risk management are overseen by its Board of Directors. The Board of Directors takes an enterprise-wide approach to risk management oversight that is designed to support the Company's business plans at a level of risk considered by the Board to be reasonable. A fundamental part of risk assessment and risk management is 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 of Directors periodically reviews the Company's business plan, factoring risk management into account. It also approves the Company's risk appetite statements, which articulate the Company's tolerance for certain risks and describes the general types of risk that the Company accepts, within certain parameters, or attempts to avoid. While the Board of Directors has the ultimate oversight responsibility for the risk management process, various committees of the Board also have responsibilities related to risk assessment and risk management, and management has responsibility for managing the risks to which the Company is exposed and reporting on such matters to the Board of Directors and applicable Board committees. to the respect risk assessment and integrity of Ambac’s • The Audit Committee oversees the management of risks financial associated with statements and its compliance with legal and regulatory requirements.

The Board of Directors receives quarterly updates from Board committees and the Board provides guidance to individual committee activities, as appropriate. In order to assist the Board of Directors in overseeing Ambac’s risk management, Ambac uses enterprise risk management, a company-wide process that involves the Board of Directors, management and other personnel in an integrated effort to identify, assess and manage a broad range of risks (e.g., credit, financial, legal, liquidity, market, model, operational, regulatory, reputational and strategic), that may affect the Company’s ability to execute on its corporate strategy and fulfill its business objectives. The Enterprise Risk Committee (“ERC”), which is a management committee, is comprised of executive and senior level management responsible for assisting in the management of the Company’s risks on an individual and aggregate basis. The ERC produces the relevant risk management information for executive and senior management and the Board of Directors. Ambac management has established other management committees to assist in managing the risks throughout the enterprise. These committees will meet monthly or as needed on an ad hoc basis. • The AAC Risk Committee's objective is to provide oversight of the key risk remediation issues impacting AAC.

INSURANCE REGULATORY MATTERS AND OTHER RESTRICTIONS Regulatory Matters United States AAC is domiciled in the state of Wisconsin and is therefore subject to the insurance laws and regulations of the State of Wisconsin and regulated by the Wisconsin Office of the Commissioner of Insurance (“OCI”) as a domestic insurer. Everspan Indemnity and its wholly owned subsidiary, Everspan Insurance Company ("Everspan Insurance") are domiciled in the state of Arizona and are therefore subject to the insurance laws and regulations of the State of Arizona and regulated by the Arizona Department of Insurance and Financial Institutions as domestic insurers. The subsidiaries of Everspan Insurance are domiciled in various States and are therefore subject to the insurance laws and regulations of their respective domiciliary States and regulated by the insurance departments of those States as domestic insurers. AAC, Everspan Insurance and its subsidiaries are also subject laws and regulations of the other jurisdictions in which they are licensed and operate as foreign insurers in such jurisdictions. See Note 8. Insurance Regulatory Restrictions to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K for further information on regulatory restrictions. insurance the to Pursuant to the terms of the Settlement Agreement and the Stipulation and Order, AAC must seek prior approval by OCI of certain corporate actions. The Settlement Agreement and Stipulation and Order include covenants which restrict the operations of AAC. The Settlement Agreement will remain in force until the surplus notes issued thereunder have been redeemed, repurchased or repaid in full. The Stipulation and Order will remain in force for so long as OCI determines it to be necessary. Certain of the Settlement Agreement may be waived with the approval of the OCI and/or the requisite percentage of holders of AAC's surplus notes. OCI's Runoff Capital Framework will help OCI determine whether to approve AAC making payments on or acquiring its surplus notes and Auction Market Preferred Shares ("AMPS") and distributing capital to AFG. the restrictions in The Insurance Distribution businesses, like other MGA/Us, program administrators and brokers, may be subject to licensing requirements and regulation by insurance regulators in various states in which they conduct business. United Kingdom The Prudential Regulatory Authority ("PRA") and Financial Conduct Authority ("FCA") (and their predecessor regulator the Financial Services Authority (“FSA”)) exercise significant oversight over Ambac UK. In 2009, the FSA limited Ambac UK’s license to undertaking only run-off related activity. As such, Ambac UK is authorized to run-off its insurance portfolio in the United Kingdom. See Note 8. Insurance Regulatory Restrictions to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K for further information on regulatory restrictions. Regulation of Change in Control Under applicable insurance law, any acquisition of control of AFG, or any other direct or indirect acquisition of control of AAC or one or more members of the Everspan group of companies, requires the prior approval (or non-disapproval) of the domiciliary regulator of the acquired company (or, in the case of AFG, the domiciliary regulators of AAC and each member of Everspan). “Control” is generally defined as the direct or indirect power to direct or cause the direction of the management and policies of a person. Any purchaser of 10% or more of the outstanding voting stock of a corporation is presumed to have acquired control of that corporation and its subsidiaries unless the applicable insurance regulator, upon application, determines otherwise. For purposes of this test, AFG believes that a holder of common stock having the right to cast 10% or more of the votes which may be cast by the holders of all shares of common stock of AFG would be presumably deemed to have control of AAC, Everspan Indemnity, Everspan Insurance and its subsidiaries within the meaning of applicable insurance laws and regulations, although insurance regulators may in their discretion deem control not to exist where, for example, control is disclaimed by a passive investor. The United Kingdom has similar requirements applicable in respect of AFG, as the ultimate holding company of Ambac UK. Dividend Restrictions, Restrictions AAC: Including Contractual Due to contractual and regulatory restrictions, AAC has been unable to pay ordinary dividends to AFG since 2008 and will be unable to pay ordinary dividends in 2024. AAC’s ability to pay dividends is restricted by the Settlement Agreement, the Stipulation and Order and the terms of its AMPS. OCI's decisions regarding dividends will be guided by OCI's Runoff Insurance Regulatory Capital Framework. See Note 8. Restrictions to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K for further information on dividends. As a result of these restrictions, substantial uncertainty remains as to AAC's ability to pay dividends to AFG and the timing of any such dividends. Pursuant to the Settlement Agreement, AAC may not make any “Restricted Payment” (which includes dividends from AAC to AFG) in excess of $5 million in the aggregate per annum, other than Restricted Payments from AAC to AFG in an amount up to $7.5 million per annum solely to pay operating expenses of AFG. Concurrent with making any such Restricted Payment to AFG for the payment of operating expenses, a pro rata amount of AAC's surplus notes would also need to be redeemed at par. The Stipulation and Order requires OCI approval for the payment of any dividend or distribution on the common stock of AAC. Under the terms of AAC’s AMPS, dividends may not be paid on the common stock of AAC unless all accrued and unpaid dividends on the AMPS for the then current dividend period Ambac Financial Group, Inc 11 2023 Form 10-K have been paid, provided that dividends on the common stock may be made at all times for the purpose of, and only in such amounts as are necessary for, enabling AFG (i) to service its indebtedness for borrowed money as such payments become due or (ii) to pay its operating expenses. If dividends are paid on the common stock as provided in the prior sentence, dividends on that all the AMPS become cumulative until accumulated and unpaid dividends have been paid on the AMPS. the date Ambac UK: The FSA amended Ambac UK’s license in 2010 such that the PRA must specifically approve any transfer of value and/or assets from Ambac UK to AAC or any other Ambac group company (including dividends), other than in respect of certain disclosed contracts between the two parties (such as in respect of a management services agreement between AAC and Ambac UK). While the UK insurance regulatory laws impose no statutory restrictions on an insurer’s ability to declare a dividend, the PRA’s and FCA’s rules governing capital extraction by insurance firms in run off require Ambac UK to consider its future capital requirements over a 3 to 5 year period in both base case and downside stress scenarios before declaring a dividend. Ambac UK annually prepares these forecasts and stress tests as part of its regulatory submissions to the PRA each April. If the stress tests and forecasts show adequate liquidity and regulatory capital buffers then, subject to PRA approval, it may be possible for Ambac UK to pay dividends to AAC in the near future. Everspan Companies: Everspan Indemnity, Everspan Insurance and its subsidiaries are also subject to regulatory restrictions on their ability to pay dividends. Everspan Indemnity and Everspan Insurance do not have sufficient earned surplus at this time to pay ordinary dividends under the insurance laws and regulations of Arizona. Furthermore, certain subsidiaries of Everspan Insurance are restricted from paying dividends to Everspan Insurance until 2025 or later, unless otherwise approved by the domestic regulator of the relevant subsidiary, pursuant to the regulatory orders approving the acquisition of those subsidiaries. Cirrata Companies: Ambac's MGA/U subsidiaries are not restricted from paying dividends or partner distributions (collectively "Distributions") to their owners or partners, including Cirrata, which is 100% owned by AFG. Ambac's established MGA/Us historically have paid Distributions equating to the majority of their individual EBITDA, subject to working capital and other capital needs, on a quarterly basis. Newly formed de-novo MGA/Us are not expected to make regular distributions to their partners until they become profitable and generate free cash flow on a steady and/ or predictable basis. INVESTMENTS AND INVESTMENT POLICY As of December 31, 2023, the consolidated non-VIE investments of Ambac had an aggregate fair value of approximately $2,664 million. Investments are primarily managed by third party investment management firms overseen internally. All investments are made in accordance with the general objectives, policies, and guidelines for investments approved by the Board of Directors of the applicable subsidiary. These policies and guidelines include liquidity, credit quality, diversification and duration objectives and are periodically reviewed and revised as appropriate. As of December 31, 2023, the AAC and Everspan non-VIE investment portfolios had an aggregate fair value of approximately $1,810 million.

In addition to internal investment policies and guidelines, the investment portfolio of each company is subject to limits on the types and quality of investments imposed by applicable insurance laws and regulations of the jurisdictions in which it is licensed. The Board of Directors of each respective subsidiary approves any changes to the respective investment policies. Within its guidelines, AAC opportunistically purchases and sells AAC and Ambac UK insured securities given their relative risk/ reward characteristics. In certain instances, AAC may exceed its established credit rating or concentration limits with appropriate regulatory approval. Changes to AAC’s investment policies are subject to approval by OCI pursuant to covenants made by AAC in the Settlement Agreement and the Stipulation and Order, and may be affected by OCI's Runoff Capital Framework as discussed above in Insurance Regulatory Matters and Other Restrictions. See Note 1. Background and Business Description to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K for more information. Such requirements could adversely impact the performance of the investment portfolio. As of December 31, 2023, the non-VIE Ambac UK investment portfolio had an aggregate fair value of approximately $663 million. Ambac UK’s investment policy is designed with the primary objectives of ensuring a reasonable risk-adjusted return over the remaining runoff of the insured portfolio and that Ambac UK is able to meet its financial obligations as they fall due, in particular with respect to policy holder claims.

As of December 31, 2023, the non-VIE AFG (parent company only, excluding investments in subsidiaries) investment portfolio had an aggregate fair value of approximately $188 million. The primary investment objective is to preserve capital for strategic uses while maximizing income. The investment portfolio is subject to internal investment guidelines. Such guidelines set forth minimum credit rating requirements and credit risk concentration limits. As of December 31, 2023, the non-VIE Insurance Distribution fair value of investment portfolio had an aggregate approximately $4 million, primarily consisting of money market funds. Ambac Financial Group, Inc 12 2023 Form 10-K liquidity, At December 31, 2023 and 2022 Ambac owned $369 and $286, respectively, of distressed AAC and Ambac UK-insured bonds, primarily RMBS and student loan bonds.

Our 2023 voluntary turnover rate was approximately 8.3%. Ambac considers its employee relations to be satisfactory. Ambac’s focus has been on identifying and retaining key talent through individual development programs following skills assessments. Ambac’s succession planning has identified internal candidates that could fill executive management and senior management positions as the need arises. The Company has established a senior advisory team to work with, and advise, executive management on key initiatives, and has invested in both personal and professional growth programs to identify and prepare individuals for promotion within the Company. The Company continues to rely on compensation components (such as salary, long-term incentive plan awards, deferred cash awards and short-term incentive plan awards) to support employee retention and discourage excessive risk taking. The Company incorporates performance metrics as part of the annual short- term incentive bonus offering with increased bonus potential for exceptional results. We utilize third-party benchmark data to establish market-based compensation levels. We believe that our current compensation and reflect high performance expectations as part of our merit pay philosophy. The targeted use of long-term equity incentive plan awards for key talent is an important element of Ambac’s long-term retention strategy. incentive levels Item 1A.

Page 13 15 23 Risks Related to AFG Common Shares The price per share of AFG's common stock may be subject including significant price declines. to a high degree of volatility, Ambac's Legacy Financial Guarantee Insurance business is in run-off and faces significant risks and uncertainties described elsewhere in Part I, Item 1A. Risk Factors. In addition, Ambac's Specialty Property and Casualty Insurance and Insurance Distribution businesses are in the early stages of development and relatively small; therefore, they are also subject to uncertainties described elsewhere in Part I, Item 1A. Risk Factors. Although AFG's common stock is listed on the New York Stock Exchange ("NYSE"), there can be no assurance as to the liquidity of the trading market or the price at which such shares can be sold. The price of the shares may decline substantially in response to a number of events or circumstances, including but not limited to: • adverse developments in our financial condition or results of operations; • changes in the actual or perceived risk within our Legacy Financial Guarantee ("LFG") insured portfolio; 82 3.0 % 65 1.9 % Our risk factors are organized in the following sections Ambac Financial Group, Inc 13 2023 Form 10-K • changes to regulatory status; • changes in investors’ or analysts’ valuation measures for our stock; • market perceptions of our success, or lack thereof, in pursuing and implementing our Specialty Property and Casualty Insurance and Insurance Distribution businesses and our new business strategy more generally; • the impact or perceived impact of any acquisition, disposition or other strategic transaction, including entry into a new line of business or the sale of all or a part of the LFG business, on the value or long-term prospects of the Company; • adverse developments in the industries and markets in which we operate, including the property and casualty insurance, underwriting and brokerage industries, or the fixed income and equity capital markets; • adverse market and/or economic conditions, such as those caused by a recession or inflation, which increase our risk of loss on insurance policies and depress the value and/or liquidity of our investments and other assets; • adverse developments in current or future litigations; and • results and actions of other participants in our industries. The price of AFG's shares may also be affected by the risks described below, including risks associated with AAC’s ability to deliver value to AFG. Investments in AFG's common stock may be subject to a high degree of volatility. AFG may not be able to realize value from its LFG businesses. The value of AFG's common stock is partially dependent upon realizing residual value from AAC by means of a full or partial sale and/or the receipt of dividends. While AFG is exploring strategic options, including the possibility of a full or partial sale of AAC and Ambac UK, AFG can provide no assurance that such a transaction will be consummated or, if consummated, whether the value obtained will ultimately prove to be greater than the value of the LFG business reflected in AFG's common stock or that could be realized in a longer-term run-off scenario. AFG may be unable to secure a binding offer for the full or partial sale of the LFG business on terms viewed as acceptable by the Board of Directors of AFG or at all. If an acceptable offer is made and accepted, the closing of the sale would be subject to several conditions, including regulatory and other approvals, which may not be satisfied. In the absence of a full or partial sale of the LFG business, the Company plans to continue to actively run-off the LFG business. See Part I, Item I. Description of Business - Legacy Financial Guarantee Insurance. There can be no assurance that AFG will be able to realize residual value through receiving dividends from the continued run-off of AAC. AFG's ability to realize residual value from AAC will depend upon, amongst other considerations, AAC's ability to satisfy all of its obligations that are senior to AFG's equity interests, including obligations to policyholders, surplus note holders and preferred stock holders. AAC's ability to satisfy all of its obligations that are senior to AFG's equity depends on a number of considerations, including its ability to recover losses previously paid; avoid material losses from litigation; mitigate losses from its insured portfolio, which is subject to significant risks and uncertainties, including as a result of varying potential perceptions of the value of AAC’s guarantees and securities; realize material value from its investment in Ambac UK; and repay and/or restructure its indebtedness in a timely manner such that accruing interest costs are manageable. Payments of principal and interest on AAC's surplus notes are subject to the express approval of the Wisconsin OCI. from losses Increased loss development in the LFG insured portfolio, or significant litigation or other events or circumstances may prompt OCI to determine that it is in the best interests of policyholders to initiate rehabilitation proceedings with respect to AAC or to issue supervisory orders that impose restrictions on AAC, either preemptively or in response to any such event or circumstance. the assertion of damages by counterparties, If OCI were to decide to initiate rehabilitation proceedings with respect to AAC, adverse consequences may result, including, without limitation and absent enforceable protective injunctive the relief, acceleration of losses based on early termination triggers, and the loss of control rights in insured transactions. Any such consequences may reduce or eliminate any residual value of AAC for AFG. Additionally, the rehabilitator would assume control of all of AAC’s assets and management of AAC. In exercising control, the rehabilitator would act solely for the benefit of policyholders, which may result in material adverse consequences for our security holders. Similar risks would arise if Ambac UK were to become subject to a proceeding to protect the interests of its policyholders, in which case AAC's ability to realize value from Ambac UK (and consequently AFG's ability to realize value from AAC) would diminish. If OCI were to issue supervisory orders imposing restrictions on AAC, AAC's ability to satisfy its obligations to policyholders or creditors, or its ability to deliver value to AFG, may be significantly constrained. Due to the above considerations, as well as applicable legal and contractual restrictions described elsewhere herein, substantial uncertainty remains as to AAC's ability to pay dividends to AFG and the timing of any such dividends. Ambac is planning to further develop and expand its Insurance and Specialty Property and Casualty Insurance Distribution businesses; however, such plans may not be realized, or if realized, may not create value and may negatively impact our financial results. The value of AFG's common stock depends in part upon the ability of Ambac to generate earnings apart from the LFG business. Ambac is planning to further develop and expand its Specialty Property and Casualty Insurance and Insurance Distribution businesses. Such plans may involve additional acquisitions of assets or existing businesses and the development of businesses through new or existing subsidiaries. Currently, it is not possible to fully predict the future prospects or other characteristics of such businesses. While we expect to conduct business, financial and legal due diligence in connection with future business or acquisition the evaluation of any opportunities, there can be no assurance our due diligence will identify every matter that could have a material adverse effect on us. Efforts to pursue certain business opportunities may be Ambac Financial Group, Inc 14 2023 Form 10-K unsuccessful or require significant financial or other resources, which could have a negative impact on our operating results and financial condition. To implement our growth strategy, we must be able to meet our capital needs, expand our systems and our internal controls effectively, allocate our human resources optimally, identify and hire qualified employees and effectively integrate any acquisitions we make in our effort to achieve growth. No assurance can be given that Ambac will successfully execute its plans for new business, generate any earnings or value from new businesses or be able to successfully integrate any such business into our current operating structure. The failure to manage our growth effectively could have a material adverse effect on our business, financial condition and results of operations. Our business performance and growth plans could be negatively affected if we are not able to, among other things, gain internal efficiencies through the application of effective technology across our businesses, integrate operations, and/or innovate product and operational solutions. Conversely, investments in internal systems or innovative product offerings may fail to yield sufficient return to cover their investment. Our ability to successfully manage ongoing organizational changes could impact our business results, where the level of costs and/or disruption may be significant and change over time, and the benefits may be less than we originally expect. Should changes in Ambac’s circumstances or financial condition or in the political, economic and/or legal environment occur, there can be no assurance that all or any part of our strategy and/ or initiatives will not be abandoned or amended to take account of such changes. Any such adjustment or abandonment may have a material adverse effect on our securities. Risks Related to the Company's Business Loss reserves for the LFG business may not be adequate to cover potential losses, and changes in loss reserves may result in further volatility of net income and comprehensive income. LFG loss reserves are established when management has observed credit deterioration in its insured credits. Loss reserves established with respect to our LFG insurance policies issued to beneficiaries are based upon estimates and judgments by management, including estimates and judgments with respect to the probability of default; the severity of loss upon default; management’s ability to execute policy commutations, restructurings and other loss mitigation strategies; and estimated subrogation and other loss recoveries. The objective of establishing loss reserve estimates is not to, and our loss reserves do not, reflect the worst possible outcomes. While our reserving scenarios reflect a wide range of possible outcomes (on a probability weighted basis), reflecting the uncertainty regarding future developments and outcomes, our loss reserves may change materially based on future developments. As a result of inherent uncertainties in the estimates and judgments made to determine loss reserves, there can be no assurance that either the actual losses in our financial guarantee insurance portfolio will not exceed such reserves or that our reserves will not materially change over time as circumstances, our assumptions, or our models change. Catastrophic events, including environmental and public health events that result in material disruption of economic activity, loss of human life or significant property damage, can have a materially negative impact on our financial and operational performance. Such stresses could result in liquidity strains or permanent losses. Public health crises and/or natural disasters can cause economic and financial disruptions that may adversely affect, our business and results of operations. For example, AAC insures the obligations of a number of issuers, such as municipalities and securitization vehicles, including those backed by consumer loans such as mortgages and student loans, that may be substantially affected by the prolonged economic effects of pandemics, other public health crises, environmental events or natural disasters. Municipalities and their authorities, agencies and instrumentalities, especially those dependent on narrow revenue streams flowing from particular economic activities, such as sales taxes, may suffer disproportionately, from depressed revenues due to the lingering negative economic impact brought about by such events. In response to such events, the U.S. Federal government and State governments and their agencies may adopt policies or guidelines to provide emergency relief to consumers, such as limiting debt collection efforts, extensions, modifications or encouraging or forbearance with respect to certain loans and fees, and establishing foreclosure and eviction moratoriums. These or similar types of emergency responses to future events may cause Ambac to experience higher losses in its insured portfolio. requiring Future environmental or other public health events and natural disasters can result in significant potential liabilities for issuers, that increase the potential for default on obligations insured by AAC and Ambac UK. Everspan may be exposed to losses arising out of unpredictable catastrophic events. These include natural catastrophes and other disasters, such as hurricanes, earthquakes, windstorms, floods, wildfires, and severe winter weather. Catastrophes can also include man-made disasters, such as terrorist attacks and other destructive acts, war, political unrest, explosions, cyber-attacks, nuclear, biological, chemical or radiological events and infrastructure failures. A severe catastrophe or a series of losses exceeding Everspan’s catastrophes could result reinsurance protection and may have a material adverse impact on our results of operations or financial condition. in Changing weather patterns and climate change have added to the unpredictability, frequency and severity of weather-related catastrophes incurred by the property and casualty insurance industry in recent years. These changing weather patterns make it more difficult to predict and model catastrophic events, reducing our ability to accurately price exposure to such events and mitigate its risks. Further, we use internally developed and third-party vendor tools and models to assess exposure to catastrophe losses. The models assume various conditions and probability scenarios and may not accurately predict future losses or measure losses currently incurred. Limitations in these tools and models may Ambac Financial Group, Inc 15 2023 Form 10-K adversely affect our results of operations and financial condition. The ultimate impact of a catastrophic event on insurers and their obligations, and the economy in general, is by its very nature uncertain, and will be determined by a number of factors including, but not limited to, the depth and duration of a particular crisis; the extent to which affected consumers, businesses, municipal entities and other debtors or sources of revenues recover from depressed economic circumstances, and the timelines for such recoveries; the level and efficacy of government intervention or support for municipal entities, consumers, businesses and the financial markets via emergency relief measures; the availability of insurance; the availability of cost-effective financing; management of public health crisis remediation efforts; the effectiveness of other public or private crisis management efforts, mitigation measures or support; and certain socio-economic variables, such as unemployment levels. Consequently, if following such catastrophic events we do not have sufficient resources or financial flexibility, receive adequate measures of support or realize the appropriate level of economic recovery, our ultimate ability to operate could be materially impaired and we could suffer material permanent losses and therefore may have an adverse effect on our results of operations and financial condition. Counterparties that service aspects of our business may be similarly impacted and, if their operations are impaired due to a catastrophe, it may be difficult or costly to us to find alternatives to such servicing capabilities. AAC and Ambac UK are subject to credit and other risks in their insured portfolios; we are also subject to risks associated with adverse selection as our insured portfolios run off. Performance of our insured LFG transactions, including (but not limited to) those backed by municipal, utility, sovereign/sub- sovereign, military housing and consumer risk, can be adversely affected by general economic conditions, such as recession, federal budget cuts, decisions of governmental authorities about utilizing assets or facilities, inflation, unemployment levels, increasing underemployment, home price depreciation, foreclosure rates, unavailability of consumer credit, mortgage product attributes, borrower and/or originator fraud or misrepresentations, and asset servicer performance and financial health. While deterioration in the performance of transactions insured by AAC and Ambac UK, including mortgage and student loan securitizations may occur, the timing, extent and duration of any future deterioration of the credit markets is unknown, as is the impact on potential claim payments and ultimate losses on the securities within our insured LFG portfolio. In addition, there can be no assurance that any governmental or private sector initiatives designed to address such credit deterioration in the markets will be successful or inure to the benefit of the transactions we insure. For example, servicer settlements with governmental authorities regarding foreclosure or servicing irregularities are generally designed to protect borrowers and may increase losses on securities we insure. In particular, the student loan industry and, specifically, trusts with securities insured by AAC have been subject to heightened Consumer Finance Protection Bureau ("CFPB") scrutiny and enforcement action over servicing and collections practices and potential chain of title issues and, consequently, any settlements, orders or penalties resulting from CFPB actions, or any failure on the part of servicers or other parties asserting claims against delinquent borrowers to establish title to the loans, could lead to increased losses on securities we insure. Issuers of public finance obligations insured by AAC have reported, or may report, budget shortfalls, significantly underfunded pensions or other fiscal stresses that imperil their ability to pay debt service or will require them to significantly raise taxes and/or cut spending in order to satisfy their obligations. Furthermore, over time, the consequences of poor public policy decisions by state and local governments or increases in tax burdens can impact demographic trends, such as out-migration from one state or municipality to another, that may negatively impact the creditworthiness of related issuers. Some issuers of obligations insured by AAC have declared payment moratoriums, defaulted or filed for bankruptcy or similar debt adjustment proceedings, raising concerns about their ultimate ability or willingness to service the debt insured by AAC and AAC's ability to recover claims paid in the future. If the issuers of the obligations in the public finance portfolio are unable to raise taxes, cut spending, or receive federal or state assistance, or if such issuers default or file for bankruptcy under Chapter 9 or for similar relief under other laws that allow for the adjustment of debts, AAC may experience liquidity claims and/ or ultimate losses on those obligations, which could adversely affect the Company's business, financial condition and results of operations. Issuers in Chapter 9 or similar proceedings may obtain judicial rulings and orders that impair creditors' rights or their ability to collect on amounts owed. In certain cases, judicial decisions may be contrary to AAC's expectations or understanding of the law or its rights thereunder, which may lead to worse outcomes in Chapter 9 or similar proceedings than anticipated at the outset. in higher As the runoff of the insured portfolio continues, the proportion of exposures we rate as below investment grade relative to the aggregate insured portfolio may increase, leaving the portfolio risk exposures and increasingly concentrated heightening risks associated with large single risk exposures to particular losses caused by catastrophic events (including public health crises, terrorist acts and natural disasters), and losses in respect of different, but correlated, credit exposures. These risks may result in greater volatility or have adverse effects on the Company's results from operations and on our financial condition. issuers, We may not be able to effectively reduce LFG insured exposures; measures taken to reduce risks may have an adverse effect on the Company's operating results or financial position. In pursuing the objective of improving our financial position, we are seeking to terminate, commute, reinsure or otherwise reduce LFG insured exposures. De-risking transactions may not be feasible or economically viable. We cannot provide any assurance that any such transaction will be consummated in the future, or if it is, as to the timing, terms or conditions of any such transaction. Even if we consummate one or more of such transactions, doing so may ultimately prove to be unsuccessful in creating value for any or all of our stakeholders and may negatively impact our operating results or financial position. Ambac Financial Group, Inc 16 2023 Form 10-K Our risk management policies and practices may not adequately identify significant risks. As described in Part I, Item 1, “Risk Management” in this Annual Report on Form 10-K, we have established risk management policies and practices which seek to mitigate our exposure to credit risk in our legacy financial guarantee insured portfolio. Ongoing surveillance of credit risks in our legacy financial guarantee insured portfolio is an important component of our risk management process. These policies and practices in the past have not insulated us from risks that were unforeseen and which had unanticipated loss severity, and such policies and practices may not do so in the future. There can be no assurance that these policies and practices will be adequate to avoid future losses. If we are not able to identify significant risks, we may not be able to timely mitigate such risks, thereby increasing the amount of losses to which we are exposed. An inability to identify significant risks could also result in the failure to timely establish loss reserves that are sufficient in relation to such risks. We operate within an enterprise risk management (“ERM”) framework designed to assess and monitor risks. However, no assurance can be given that we will effectively identify, review, monitor or manage all relevant risks. Nor can we provide assurance that our ERM framework will result in us accurately identifying all risks and adequately limiting our exposures based on our assessments. Any ineffectiveness in our controls or procedures or failure to manage these risks may have an adverse effect on our results of operations and financial condition. The Settlement Agreement, Stipulation and Order and OCI's Runoff Capital Framework may impair AAC's ability to pursue its business strategies. Pursuant to the terms of the Settlement Agreement and Stipulation and Order, AAC must seek prior approval by OCI of certain corporate actions. The Settlement Agreement and Stipulation and Order also include covenants that restrict the operations of AAC which (i) in the case of the Settlement Agreement, remain in force until the surplus notes that were issued pursuant to the Settlement Agreement have been redeemed, repurchased or repaid in full, and (ii) in the case of the Stipulation and Order, remain in place until the OCI decides to relax such restrictions. Certain of these restrictions may be waived with the approval of holders of surplus notes and/or OCI. If we are unable to obtain the required consents under the Settlement Agreement and/or the Stipulation and Order, AAC may not be able to execute its planned business strategies. In addition, OCI's Runoff Capital Framework and decisions based thereon are expected to affect AAC's ability to reduce financial leverage at AAC, pay dividends to AFG, and/or make payments on surplus notes or AMPS. OCI has certain enforcement rights with respect to the Settlement Agreement and Stipulation and Order, and retains full discretion over the design of, and assumption utilized in, OCI's Runoff Capital Framework and the implications thereof. Disputes may arise over the interpretation of such agreements or instruments, the exercise or purported exercise of rights thereunder, the performance of or failure or purported failure to adhere to the terms thereof. Any such dispute could have material adverse the determinations made thereunder, or effects on AAC, and the Company more broadly, whether litigation, administrative proceedings, supervisory through orders, failure to execute transactions sought by management, interference with corporate strategies, objectives or prerogatives, inefficient decision-making or execution, forced realignment of resources, increased costs, distractions to management, strained working relationships or otherwise. Such effects would also increase the risk that OCI would seek to initiate rehabilitation proceedings or issue supervisory orders against AAC. We use analytical models and tools to help project performance of our insured LFG obligations and our investment portfolio but actual results could differ materially from model and tool outputs and related analyses. We rely on internally and externally developed complex financial models, including default models related to RMBS and a waterfall tool provided by a nationally recognized vendor for RMBS and student loan exposures, to project performance of our insured LFG obligations and similar securities in our investment portfolio. These models and tools assume various conditions, probability scenarios, facts and circumstances, and there can be no assurance that such models or tools accurately predict or measure the quantum of losses, loss reserves and timing of losses. Differences in the models and tools that we employ, uncertainties or flaws in these financial models and tools, or faulty assumptions inherent in these financial models and tools or those determined by management could lead to material changes in projected outcomes, and could include increased losses, loss reserves and/or credit impairments on the investment portfolio. Moreover, estimates of transaction performance depend in part on the interpretation of contracts and other bases of our legal rights. Such interpretations may prove to be incorrect or different interpretations may be employed by bond trustees and other transaction participants and, ultimately courts, which could lead to increased losses, loss reserves and/or investment impairments. We are subject to the risk of litigation and the outcome of proceedings we are or may become involved in could have a material adverse effect on our business, operations, financial position, profitability or cash flows. AAC is defending or otherwise involved in various lawsuits relating to its LFG business. Please see Note 19. Commitments and Contingencies to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K for information on various proceedings. It is not possible to predict the extent to which additional suits involving AFG, AAC or one or more other subsidiaries will be filed, and it is also not possible to predict the outcome of litigation. It is possible that there could be unfavorable outcomes in existing or future proceedings. Management may be unable to make meaningful or reasonable estimates of the amount or range of losses that could result from unfavorable outcomes or of the expenses that will be incurred in connection with such lawsuits. Under some circumstances, adverse results in any such proceedings and/or the incurring of significant litigation or other expenses could be material to our business, operations, financial position, profitability or cash flows. Ambac Financial Group, Inc 17 2023 Form 10-K Everspan may be subject to disputes with policyholders regarding the scope and extent of coverage offered under Everspan's policies; be required to defend claimants in suits against its policyholders for covered liability claims; face allegations of into commercial disputes with its reinsurers, MGA/Us or TPAs regarding their respective contractual obligations and rights. Under some circumstances, the results of such disputes or suits may lead to liabilities beyond those which are anticipated or reserved. improper claims handling; or enter Political developments may materially adversely affect our business. local or foreign government Our insurance businesses and our results of operations can be materially affected by political developments at the federal, state levels. Government and/or shutdowns, trade disputes, political turnover, judicial decisions, adverse changes in governmental funding, or poor public policy decision making could disrupt the national, international and local economies where we have insured exposures. In addition, we are exposed to correlation risk as a result of the possibility that multiple credits, counterparties, or portfolios may concurrently and/or consecutively experience losses or increased stress as a result of any such event or series of events. We operate in in a highly regulated industry and our business will be negatively affected if we are not able to anticipate and keep pace with rapid changes in government laws and regulations or if government laws and regulations impair our business or increase our costs. Our U.S. LFG and Specialty Property and Casualty Insurance subsidiaries are highly regulated as insurance carriers in the States of their domicile and the jurisdictions in which they are licensed. Our owned MGA/Us and insurance brokerage subsidiaries are also required to maintain certain entity-level licenses as well as individual officers or licenses of representatives that are essential to their ability to conduct business. Each of the foregoing must also comply with laws generally applicable to insurance entities, including those relating to governance, capital, and operational requirements. of and technology, social Government laws and regulations applicable to our businesses develop and change rapidly in response to consumer demands and public policies. State legislatures and insurance departments place increasing burdens on insurance carriers and producers with respect to matters such as cybersecurity, data privacy, governance, management environmental risk management. Such laws and regulations require substantial resources to ensure that the Company has appropriate and effective compliance programs in place. If we are unable to keep pace with changes in applicable law and regulations, or if we otherwise fail in our compliance efforts, the Company may fines, sanctions, governmental orders or be subject modifications individually or collectively impair our business or increase our costs, possibly materially. to business practices corporate and enterprise issues, that to In addition, the Company from time to time receives various regulatory inquiries and requests for information, and its insurance carrier subsidiaries are subject to examination by regulatory authorities. It is not possible to predict the extent to which additional regulatory inquiries or requests for information will be made, nor the outcome of inquiries, requests for information or examination, which exposes the Company to potential fines, sanctions, governmental orders or modifications to business practices that individually or collectively impair our business or increase our costs, possibly materially. Actions of the PRA and FCA could reduce the value of Ambac UK realizable by AAC, which would adversely affect our securityholders. Ambac’s international business is operated by Ambac UK, which is regulated by the Prudential Regulation Authority (“PRA”) for prudential purposes and the Financial Conduct Authority (“FCA”) for conduct purposes. The terms of Ambac UK’s regulatory authority are now restricted and Ambac UK is in run-off. Among other things, Ambac UK may not write any new business, and, with respect to any entity within the Ambac group of affiliates, commute, vary or terminate any existing financial guaranty policy, transfer certain assets, or pay dividends, without the prior approval of the PRA. The PRA and FCA act generally in the interests of Ambac UK policyholders and will not take into account the interests of AAC or the securityholders of Ambac when considering whether to provide any such approval. Accordingly, determinations made by the PRA and FCA, in their capacity as Ambac UK’s regulators, could potentially result in adverse consequences for our securityholders and also reduce the value realizable by AAC for Ambac UK. Regulatory uncertainty in relation to Ambac UK’s capital position could adversely affect the value of Ambac UK and affect our securityholders. Ambac UK is required to meet certain minimum capital requirements under applicable rules ("Solvency II"). Ambac UK exceeded the required capital thresholds as of December 31, 2023 . regulatory capital However, there remains a risk that market movements impacting its investments or adverse credit developments impacting loss reserving requirements within its insured portfolio could result in the capital position becoming deficient once again. Everspan may not be successful in executing its business plans or may experience greater than expected losses and/or reinsurance insurance underwriting losses counterparty material to Everspan's capital position, a downgrade of its AM Best rating and a loss of its franchise value. Such events could have a material adverse impact on the value of AFG's shares. losses, which could result in Everspan is in the early stage of developing a portfolio of specialty insurance program business. Its business plan entails establishing programs with program administrators, managing general agents and managing general underwriters ("MGA/Us"), with claims handled by TPAs. The success of these programs is dependent upon the quality of insurance risk underwritten by the MGA/Us, the quality of underwriting and operational performance, as well as oversight, of the MGA/Us and TPAs by Ambac Financial Group, Inc 18 2023 Form 10-K Everspan, the quality and creditworthiness of reinsurance obtained with respect to the underlying risks, loss experience over time, premium levels, competition and other factors, some of which are outside Everspan's control. Should Everspan fail in executing its business plans or experience greater than expected losses due to operational issues, poor risk selection, default or failure to perform by reinsurers, failure to timely realize ultimate loss exposure, a departure of qualified MGA/Us from the industry, enhanced scrutiny from regulators or ratings agencies specific to the program business model, failure to collect amounts due to it or other factors, Everspan may suffer losses that are material to its capital position, a downgrade in its AM Best rating and/or a loss of its franchise value. Any such outcomes could have a material adverse impact on the value of AFG's shares. A downgrade in the AM Best financial strength rating of Everspan may negatively affect our business. to meet obligations The financial strength of Everspan is evaluated by AM Best, which issues a "FSR, an important factor in establishing the competitive position of Everspan. The FSR reflects AM Best’s opinion of Everspan's financial strength, operating performance, strategic position and ability to policyholders, and are not evaluations directed to investors. Everspan's FSR is subject to periodic review, and the criteria used in the rating methodologies are subject to change. All of the insurance companies that comprise Everspan are rated "A-" (Excellent). A downgrade in Everspan's FSR could make it more difficult insurance policies and Everspan's distribution channels may cease to transact with them, which would adversely affect our business, financial condition and results of operations. to sell Failure of Everspan's Program Partners to properly market, underwrite or administer policies could adversely affect us. The marketing, underwriting, administration and servicing of policies in our Specialty Property and Casualty Insurance business have been contracted to the MGA/Us with which Everspan transacts. Any failure by the MGA/Us or TPAs to properly handle these functions could result in liability to us. Even though the MGA/Us and TPAs with which Everspan transacts may be required to indemnify Everspan for any such liability or monetary losses, there are risks for which indemnity may be insufficient or entirely unavailable if, for example, the relevant program partner becomes insolvent or is otherwise unable to pay us. Furthermore, any failure to properly handle the marketing, underwriting, administration and servicing of policies in our Specialty Property and Casualty Insurance business could also create regulatory issues or harm our reputation, which could materially and adversely affect our business, financial condition and results of operations. If in our Specialty Property and Casualty Insurance business we are unable to accurately underwrite risks and charge competitive yet profitable rates to our clients and policyholders, our business, financial condition and results of operations may be adversely affected. In general, the premiums for our Specialty Property and Casualty Insurance policies are established at the time a policy is income, investment issued and, therefore, before all of our underlying costs are known. Like other property and casualty insurance companies, Everspan relies on estimates and assumptions in setting its rates rates. Establishing adequate premium premium is necessary, to generate together with sufficient revenue to offset losses, loss adjustment expenses, acquisition costs and general and administrative expenses in order to earn a profit. The rate environment is also subject to market cycles, which can be difficult to predict and make it difficult to adequately price risk. If Everspan does not accurately assess the risks that it assumes, it may not charge adequate premiums to cover its losses and expenses, which would adversely affect our results of operations and our profitability. Alternatively, Everspan could set its premiums too high, which could reduce its competitiveness and lead to lower policyholder retention, resulting in lower revenues. Pricing is a highly complex exercise involving the acquisition and analysis of historical loss data and the projection of future trends, loss costs, expenses, and inflation trends, among other factors, for each of Everspan's products in multiple risk tiers and many different markets. Everspan seeks to implement its pricing accurately in accordance with its assumptions. Everspan's ability to undertake these efforts successfully and, as a result, to accurately price its policies, is subject to a number of risks and uncertainties, including insufficient or unreliable data; incorrect or incomplete analysis of available data; uncertainties generally inherent in estimates and assumptions; failure to implement appropriate actuarial projections and ratings formulas or other pricing methodologies; regulatory constraints on rate increases; failure to accurately estimate investment yields and the duration loss adjustment expenses; of disagreements with reinsurers or the MGA/Us with whom Everspan transacts as to the adequacy of pricing assumptions; and unanticipated court decisions, legislation or regulatory action. losses and liabilities for If Everspan is unable to obtain reinsurance coverage at reasonable prices or on terms that adequately protect it, we may be required to bear increased risks or reduce the level of our underwriting commitments. Everspan purchases reinsurance as part of its overall risk management strategy. While reinsurance does not discharge our insurance subsidiaries from their obligations to pay claims for losses insured under their insurance policies, it does make the reinsurer liable to them for the reinsured portion of the risk. At the inception of a new program, Everspan generally acts as an issuing carrier and reinsures a majority of such risk to third parties in contracts that are generally subject to term limitations or termination rights. Everspan may be unable to maintain its current reinsurance arrangements or to obtain other reinsurance in adequate amounts and at favorable rates, particularly if reinsurers become unwilling or unable to support our specialty property and casualty business in the future. Additionally, market conditions beyond our control may the availability and cost of reinsurance and could have an adverse effect on our business, financial condition and results of operations. A decline in the availability of reinsurance may increase the cost of reinsurance and materially and adversely affect our business prospects. Everspan may, at certain times, be forced to incur additional costs for reinsurance or may be unable to obtain sufficient reinsurance on acceptable terms or from impact Ambac Financial Group, Inc 19 2023 Form 10-K reinsurers which satisfy Everspan's criteria as acceptable security. In the latter case, Everspan would have to accept an increase in exposure to risk, reduce the amount of business written by it or seek alternatives in line with Everspan's risk limits, all of which could adversely affect our business, financial condition and results of operations. to whom we outsource Counterparties functions, including policy and claims administration, such as MGAs and TPAs, may default on their operational and financial obligations to us. We have outsourced certain processes and functions to third parties over which we have no control and may continue to do so in the future. Outsourcing functions to third parties exposes us to increased risk related to service disruptions. Further, we may suffer financial losses if a counterparty defaults on a financial obligation to us, including with respect to insurance agency commissions which adjust over time. If we do not effectively develop, implement and monitor these relationships and the solvency of our counterparties, the providers do not perform as anticipated, technological or other problems are incurred, or such relationships are terminated, we may not realize expected productivity improvements or cost efficiencies and may experience operational difficulties, increased costs, and a loss of business. Further, policyholders and claimants may suffer delays or lapses in service levels which may create extra- contractual exposures. The increased risks identified above could expose us to disruption of service, monetary and reputational damages, competitive disadvantage and significant increases in compliance costs. Our to insurance carrier subsidiaries are subject reinsurance counterparty credit risk. Their reinsurers may not pay on losses in a timely fashion, or at all. Our insurance carrier subsidiaries purchase reinsurance to transfer part of the risk they have underwritten to reinsurance companies in exchange for part of the premium they receive in connection with the risk. Although reinsurance makes reinsurers liable to our carriers for the risk transferred or ceded to the reinsurers, it does not relieve our insurance carrier subsidiaries of their liabilities to policyholders. Accordingly, our insurance carrier subsidiaries are exposed to credit risk with respect to their reinsurers, especially to the extent reinsurance receivables are not sufficiently secured by collateral or do not benefit from other credit enhancements. Our insurance carrier subsidiaries also bear the risk that they are unable to receive, or there is a substantial delay in receiving, the reinsurance recoverable for any reason, including that the terms of the reinsurance contract do not reflect the intent of the parties to the contract; there is a disagreement between the parties as to their intent; the terms of the contract cannot be legally enforced; the terms of the contract are interpreted by a court or arbitration panel differently than intended by our insurance carrier subsidiaries; the reinsurance transaction performs differently than our insurance carrier subsidiaries anticipated due the reinsurance structure, terms or conditions; or changes in law and regulation, or in the interpretation of laws and regulations, affects a reinsurance transaction. These risks my be exacerbated to the extent that our insurance carrier subsidiaries' reinsurance recoverables are overly concentrated with one or a small subset of reinsurers. to a flawed design of The insolvency of one or more of our insurance carrier subsidiaries' reinsurers, or their inability or unwillingness to make timely payments if and when required under the terms of reinsurance contracts, could adversely affect our business, financial condition and results of operations. If actual claims exceed loss and loss adjustment expense reserves for Everspan, or if changes in the estimated level of loss and loss adjustment expense reserves are necessary, including as a result of, among other things, changes in the legal/ tort, regulatory and economic environments in which Everspan operates, our financial results could be materially and adversely affected. reserves loss adjustment expense Loss and represent management estimates of what the ultimate settlement and These estimates are administration of claims will cost. developed using common and industry accepted actuarial techniques. Nevertheless, the process of estimating loss and loss adjustment expense reserves involves a high degree of judgment and is subject to a number of variables, which can be affected by internal and external events, such as changes in claims handling, changes in loss cost trends, catastrophic events and social inflation. Elevated social inflation trends are likely to continue. Social inflation, which includes increased litigation, partially supported by access to litigation financing; changes in social norms; an erosion of the public sentiment towards insurers’ interpretation of coverage levels and limits; and increased damage awards by juries, may make it difficult for Everspan to estimate loss reserves, establish adequate product pricing, and maintain a strong competitive position with consumers. Moreover, the impact of catastrophic events may not be adequately reflected in claims reserves and, accordingly, could adversely impact results. Catastrophic losses are caused by wind and hail, wildfires, tornadoes, hurricanes, tropical storms, earthquakes, severe freeze events, volcanic eruptions, terrorism, cyber attacks, civil unrest, and industrial accidents and other such events. We also face potential exposure to various types of new and emerging tort claims which were not known or anticipated when our insurance products were originally priced. The impact of many of these items on ultimate costs for claims and claim adjustment expense reserves could be material and is difficult to estimate. Our ability to grow Everspan will depend in part on the addition of new Program Partners, and our ability to effectively onboard such new Program Partners could have an adverse effect on our business, financial condition and results of operations. Our ability to grow Everspan will depend in part on the addition of new MGA/Us. If Everspan does not effectively and timely source, evaluate and onboard new MGA/Us, including assisting such MGA/Us to quickly resolve any post-onboarding matters and provide effective ongoing support, Everspan's ability to add new MGA/Us and its relationships with its existing Program Partners could be adversely affected. Additionally, Everspan's Ambac Financial Group, Inc 20 2023 Form 10-K reputation with potential new MGA/Us could be damaged if it fails to effectively onboard MGA/Us with whom it has signed definitive legal agreements. Such reputational damage could make it more difficult for Everspan to attract new and retain existing program partners, which could have an adverse effect on our business, financial condition and results of operations. We compete with a large number of companies in the property for underwriting premium. insurance industry casualty and intense competition for premium, We compete with a large number of companies in the property and casualty insurance industry for underwriting premium. During periods of in particular, our Specialty Property and Casualty Insurance and Insurance Distribution businesses may be challenged to maintain competitiveness with other companies that may seek to write policies without the same regard for risk and profitability targeted by our Specialty Property and Casualty Insurance and Insurance Distribution businesses. During these times, it may be difficult for Everspan or our MGA/Us to grow or maintain premium volume without lowering underwriting standards, sacrificing income, or both. In addition, our Specialty Property and Casualty Insurance and Insurance Distribution businesses face competition from a wide range of specialty insurance companies, underwriting agencies and intermediaries, as well as diversified financial services companies that are significantly larger than our specialty property and casualty insurance and insurance distribution businesses are and that have significantly larger financial, marketing, management and other resources. Some of these competitors also have longer standing and better established market recognition than Everspan does. The greater resources or market presence that these competitors possess may enable them to avoid or defray particular costs, employ greater pricing flexibility, have a higher tolerance for risk or loss, or exploit other advantages that may make it more difficult for us to compete. We may incur increased costs in competing for underwriting revenues in this environment. If we are unable to compete effectively in the markets in which our Specialty Property and Casualty Insurance and Insurance Distribution businesses operate or expand into, our underwriting revenues may decline, as well as overall business results. Impairment of intangible assets and goodwill, resulting from acquisitions, could adversely affect our results of operations. In connection with Ambac’s acquisition of insurance distribution businesses (MGA/Us and brokers), Ambac recorded the fair value of identifiable intangible assets (primarily related to distribution relationships) and goodwill. The intangible assets will be amortized over their remaining useful lives. The Company will test intangible assets for impairment if certain events occur or circumstances change indicating that the carrying amount of the intangible asset may not be recoverable. Goodwill will be tested for impairment annually or whenever events occur or circumstances change that may indicate impairment. Intangible asset and goodwill impairments are driven by a variety of factors, which could include, among other things, declining future cash flows of the acquired business as addressed in other risk factors related to the Insurance intangible asset or goodwill Distribution Business. Any impairment could adversely affect the Company's operating results and financial condition. Our Insurance Distribution businesses derive a significant portion of their commission revenues from a limited number of insurance companies, the loss of any of which could result in lower commissions or loss of business production. The commissions of our MGA/Us and insurance broker were derived from insurance policies underwritten by a limited number of insurance companies. Should one or more of these insurance companies terminate its arrangements with our Insurance Distribution businesses or otherwise decrease the number of insurance policies underwritten for it, we may lose significant commission revenues or lose significant business to production while seeking other underwrite the business. insurance companies Our Insurance Distribution businesses, results of operations, financial condition and liquidity may be materially adversely affected by certain potential claims or proceedings. Our owned MGA/Us and insurance brokerage operating subsidiaries are subject to various potential claims and other proceedings, including those relating to alleged errors and omissions in connection with the placement or servicing of insurance and/or the provision of services in the ordinary course of business, of which we cannot, and likely will not be able to, predict the outcome with certainty. Because our MGA/Us and insurance brokerage operating subsidiaries often assist customers with matters involving substantial amounts of money, including the placement of insurance and the handling of related claims that customers may assert, errors and omissions, claims against it may arise alleging potential liability for all or part of the amounts in question. Also, the failure of an insurer with whom our MGA/Us and insurance brokerage operating subsidiaries place business could result in errors and omissions claims against it by its customers, which could adversely affect Ambac’s results of operations and financial condition. Claimants may seek large damage awards, and these claims may involve potentially significant legal costs and damages. In addition, regardless of monetary costs, these matters could have a material adverse effect on our reputation and cause harm to carrier, customer or employee relationships, or divert personnel and management resources. Acquiring new MGA/Us is core to our Insurance Distribution business strategy. Risks associated with such endeavors could adversely affect our growth and results of operations. Acquisitions have been an important contributor of growth in that the Insurance Distribution business and we believe additional acquisitions will be important to maintaining future growth. Failure identify and complete acquisitions likely would result in us achieving slower growth. Moreover, to achieve anticipated revenue and earnings levels could result in slower than anticipated growth and result in intangible asset or goodwill impairment charges. the failure of acquisition successfully targets to Ambac Financial Group, Inc 21 2023 Form 10-K The current market share of our Insurance Distribution increased businesses may decrease because of competition from technology insurance companies, companies and the financial services industry, as well as the shift away from traditional insurance markets. The insurance distribution business is highly competitive and we actively compete with numerous firms for customers and insurance companies, many of which have relationships with insurance companies or have a significant presence in niche insurance markets that may give them an advantage. Other competitive concerns may include pricing, the entrance of technology companies into the insurance distribution business and the direct-to-consumer insurance carriers that do not utilize third party agents and brokers as production sources. Additionally, experience consolidation, and therefore we may experience increased competition from insurance companies and the financial services industry, as a growing number of larger financial institutions increasingly, and aggressively, offer a wider variety of financial services, including insurance distribution services. While we collaborate and compete in these segments on a fee-for-service basis, we cannot be certain that such alternative markets will provide the same level of insurance coverage or profitability as traditional insurance markets. industry may insurance the Technological changes to the way insurance is distributed, underwritten, and administered also present competitive risks. For example, our competitive position could be impacted if we are unable to cost-effectively deploy technology, such as machine learning and artificial intelligence, which collects and analyzes large sets of data to make underwriting or other decisions, or if our competitors collect and use data which we do not have the ability to access or use. In addition, usage-based methods of determining premiums (e.g., telematics) can impact product pricing and design and are becoming an increasingly important competitive factor. The landscape of law and regulation governing these areas presents additional risk to the extent we are unable to timely adapt to ensure compliance. Changes in law or in the functioning of the healthcare market could significantly impair Xchange’s business and therefore negatively impact Ambac’s financial condition and results of operations. has industry. While Xchange Adoption of a single payer healthcare system or a public health insurance option would likely adversely impact the entire healthcare historically demonstrated an ability to adjust its products to major changes in the healthcare industry, given its focus on Accident and Health products, Xchange would likely be adversely impacted by such a material change in the U.S. healthcare system particularly if private health insurance is eliminated, materially limited, or is rendered noncompetitive. Material adverse developments to Xchange's business would have a negative impact on Ambac's financial condition and results of operations which could be material. Our Insurance Distribution businesses and their results of operations and financial condition may be adversely affected by conditions that result in reduced insurer capacity. Our Insurance Distribution business results of operations depend on the continued capacity of insurance carriers to underwrite risk and provide coverage, which depends in turn on those insurance companies’ ability to procure reinsurance. Capacity among insurance carriers and reinsurers may diminish because of our performance or due to factors outside our control. For example, capacity could be reduced by insurance companies failing or withdrawing from writing certain coverages that our Insurance Distribution businesses offer to their customers. To the extent that reinsurance becomes less widely available or significantly more expensive, we may not be able to procure the amount or types of coverage that our customers desire and the coverage we are able to procure for our customers may be more expensive or limited. Variations in commission income that results from the timing of policy renewals and the net effect of new and lost business production may have unexpected effects on our results of operations. Commission income can vary quarterly or annually due to the timing of policy renewals and the net effect of new and lost business production. We do not control the factors that cause these variations. Specifically, customers’ demand for insurance products can influence the timing of renewals, new business and lost business (which includes policies that are not renewed), and cancellations. Quarterly and annual fluctuations in revenues based upon increases and decreases associated with the timing of new business, policy renewals and payments from insurance companies may adversely affect our financial condition, results flows. Profit-sharing contingent of operations and cash commissions are paid by insurance companies based upon the profitability of the business placed with such companies. In the past these commissions have accounted for a significant amount of total commissions and fees. Due to, among other things, the inherent uncertainty of loss and changes in underwriting criteria by insurance companies, there will be a level of uncertainty related to the payment of profit-sharing contingent commissions. System security risks, data protection breaches and cyber-attacks could adversely affect our business and results of operations. We and our vendors and contractual counterparties rely on our information technology systems for many enterprise-critical functions and a prolonged failure or interruption of these systems for any reason could cause significant disruption to our operations and have a material adverse effect on our business, financial condition and operating results. Our information technology and application systems, as well as those of our vendors and contractual counterparties, may be vulnerable to threats from computer viruses, natural disasters, unauthorized access, cyber-attack and other similar disruptions. Computer hackers may be able to penetrate our network’s system security, or the network's security system of a vendor or contractual counterparty, and misappropriate or compromise confidential information, create system disruptions or cause shutdowns. The ability of hackers to infiltrate and compromise our information Ambac Financial Group, Inc 22 2023 Form 10-K systems or the contents thereof may be enhanced by generative artificial intelligence, which may be more difficult to detect and defend. In addition to our own confidential information, we and our vendors and contractual counterparties sometimes receive and are required to protect confidential information obtained from third parties (including us in the case of a vendor or contractual counterparty) and personally identifiable information of individuals. To the extent any disruption or security breach results in a loss or damage to our data (or the data of a vendor or contractual counterparty on which we rely), or inappropriate disclosure of our confidential information or that of others, or personally identifiable information of individuals, it could cause significant financial losses that are either not, or not fully, insured against, cause damage to our reputation, affect our relationships with third parties, lead to claims against us, result in regulatory action, or otherwise have a material adverse effect on our business or results of operations. In addition, we may be required to incur significant costs to mitigate the damage caused by any security breach, or to protect against future damage. Moreover, although we have incident response, disaster recovery and business continuity plans in place, we may not be able to adequately execute these plans in a timely fashion in the event of a disruption to our information technology and application systems. Additionally, we are an acquisitive organization and the process of integrating the information systems of the businesses we acquire is complex and exposes us to additional risk as we might not adequately identify weaknesses in the targets’ information systems, which could expose us to unexpected liabilities or make our own systems more vulnerable to attack. We may be adversely affected by failures in services or products provided by third parties. We outsource and may further outsource certain technology and business process functions, and rely upon third-party vendors and contractual counterparties for other essential services and information, such as the provision of data used in setting loss reserves. If we do not effectively develop, implement and monitor our vendor and contractual counterparty relationships, if third party providers do not perform as anticipated, if we experience technological or other problems, or if vendor or other contractual relationships relevant to our business process terminated, we may not realize expected functions are improvements or cost efficiencies and may productivity experience operational difficulties, increased costs and a loss of business. A material failure by an external service or information provider or a material defect in the products, services or information provided thereby could adversely affect results of operations. Our our outsourcing of certain technology and business process functions to third parties may expose us to increased risk related to data security, service disruptions or the effectiveness of our control system. These risks could increase as vendors increasingly offer cloud-based software services rather than software services which can be run within our data centers or as we choose to move additional functions to the cloud. financial condition and Our ability to attract and retain qualified executives, senior managers and other employees or the loss of any of these personnel could negatively impact our business. Our ability to execute on our business strategies depends on the retention and recruitment of qualified executives and other professionals. We rely substantially upon the services of our current executive and senior management teams. In addition to these officers, we rely on key staff with insurance, underwriting, business development, credit, risk management, structured finance, investment, accounting, finance, legal, technology and other technical and specialized skills. The market for qualified executives, senior managers and other employees has become very competitive. As a result of the run-off status of AAC and the early-stage status of AFG's other businesses, we may experience higher employee turnover and finding qualified replacements may be more difficult. The loss of the services of members of our executive and/or senior management teams or our inability to hire and retain other talented personnel could delay or prevent us from succeeding in executing our strategies, which could negatively impact our business. Our business could be negatively affected by actions of stakeholders whose interests may not be aligned with the broader interests of our stockholders. Ambac could be negatively affected as a result of actions by stakeholders whose interests may not be aligned with the broader interests of our stockholders, and responding to any such actions could be costly and time-consuming, disrupt the attention of management and operations and divert employees. Such activities could interfere with our ability to execute on our strategic plans. Risks Related to Capital, Liquidity and Credit Markets substantial AAC has indebtedness, which could adversely affect our financial condition, operational flexibility and our ability to obtain financing in the future. AAC is highly leveraged. AAC’s ability to make payments on and/or refinance its surplus notes and to fund its operations will depend on its ability to generate substantial operating cash flow and on the performance of the LFG insured portfolio. AAC’s cash flow generation will depend on receipt of premiums, investment returns, and dividends and capital distributions from Ambac UK, offset by policyholder claims, commutation payments, reinsurance premiums, costs and potential losses from litigation, operating and loss adjustment expenses, and interest expense, all of which may be subject to prevailing economic conditions and to financial, business and other factors, many of which are beyond our control and many of which may be event- driven. There is substantial risk that AAC may not have the financial resources necessary to pay its surplus notes in full due to risks associated with its cash flow, insured portfolio, and other liabilities, as discussed elsewhere in these Risk Factors. If AAC cannot pay its obligations from operating cash flow, it will have to take actions such as selling assets, restructuring or refinancing its surplus notes or seeking additional capital. Any of these remedies may not, if necessary, be effected on Ambac Financial Group, Inc 23 2023 Form 10-K commercially reasonable terms, or at all. The value of assets to be sold will depend on market and economic conditions; the availability of buyers; the requirements and conditions of local law, including regulatory restrictions; and other factors that may result in AAC or a party enforcing rights against AAC to be unable to receive proceeds sufficient to discharge AAC's obligations. Furthermore, the ability of creditors or claimants to realize upon any assets, may also be subject to bankruptcy and insolvency law limitations or similar limitations applicable in insurance company rehabilitation or liquidation proceedings. Because of these and other factors beyond our control, AAC may be unable to pay or discharge the principal or interest on its surplus notes, which would impair AAC's value and the value of AFG. Surplus note principal and interest payments cannot be made without the approval of the OCI, which OCI will grant or withhold in its sole discretion. OCI's determinations about whether and when to authorize surplus note payments could materially impact the Company's financial position. Ambac can provide no assurance as to when surplus note principal and interest payments will be made. If OCI does not approve payments on or the acquisition of surplus notes over time, the ongoing accretion of interest on the notes may impair AAC's ability to extinguish the notes in full. Surplus notes are subordinated in right of payment to policyholder and other claims. AAC's substantial indebtedness could have other significant consequences for our financial condition and operational flexibility. For example, it could: • increase our vulnerability to general adverse economic, competitive and industry conditions; • limit our ability to obtain additional financing in the future for working capital, capital expenditures, acquisitions, general corporate purposes or other purposes on satisfactory terms or at all; • require AAC to dedicate a substantial portion of its cash flow from operations to the payment of surplus notes, thereby reducing the funds available for operations and to fund the execution of key strategies, including the return of capital to AFG; • limit or restrict AFG from making strategic acquisitions or cause us to make non-strategic divestitures; • limit AAC's ability, or increase the costs, to refinance surplus notes or repay surplus notes due to ongoing interest accretion; and • limit our ability to attract and retain key employees. Despite current indebtedness levels, we may incur additional debt. While restrictive covenants in certain of our contracts may limit the amount of additional indebtedness AAC may incur, we may obtain waivers of those restrictions and incur additional indebtedness in the future. In addition, if Ambac incurred indebtedness, its ability to make scheduled payments on, or refinance, any such indebtedness may depend on the ability of our subsidiaries to make distributions or pay dividends, which in turn will depend on their future operating performance and contractual, legal and regulatory restrictions on the payment of distributions or dividends to which they may be subject. There can be no assurance that any such dividends or distributions would be made. This could further exacerbate the risks associated with AAC's substantial leverage. Our inability to realize the expected recoveries included in our financial statements could adversely impact our liquidity, financial condition and results of operations and the value of our securities. We expect to recover material amounts of claims payments through cash flows in the securitization structures of transactions that AAC insures. Realization of such expected recoveries is subject to various risks and uncertainties, including the rights and defenses of other parties with interests that conflict with AAC’s interests, the performance of the collateral and assets backing the obligations that AAC insures, the performance of servicers involved in securitizations in which AAC participates as insurer, as well as numerous regulatory, legal and compliance considerations and risks. Adverse developments with respect to any of the factors described above may cause our recoveries to fall below expectations, which could have a material adverse effect on our financial condition, including our capital and liquidity, and may result in adverse consequences such as impairing the ability of AAC to honor its financial obligations, particularly its surplus notes and preferred stock obligations; initiation of rehabilitation proceedings against AAC; eliminating or reducing the possibility of AAC delivering value to AFG, through dividends or otherwise; and a significant drop in the value of securities issued or insured by AFG or AAC. the Revenues and cash flow will be adversely impacted by a decline in realization of installment premiums. A significant percentage of our LFG premium revenue is attributable to installment premiums. The amount of installment premiums we collect is declining along with the insured portfolio. The amount of installment premiums we actually realize could be further reduced due to factors such as early termination of insurance contracts, new reinsurance transactions, accelerated prepayments of underlying obligations or insufficiency of cash flows (by the premium paying entity). The reduction in installment premiums will result in lower revenues and cash flow in the future. We may have future capital needs and may not be able to obtain third-party financing or raise additional third- party capital on acceptable terms, or at all. An inability to obtain third-party debt financing or raise additional third-party capital, when required by us or when business conditions warrant, could have a material adverse effect on our business, financial condition and results of operations, and could adversely impact our ability to achieve our strategic objectives. Our financial condition, the risks described elsewhere in Part I, Item 1A in this Annual Report on Form 10- K for the fiscal year ended December 31, 2023, as well as other factors, may constrain our financing abilities. Our ability to secure third-party financing will depend upon our future operating performance, regulatory conditions, the availability of credit generally, economic conditions and financial, business and other factors, many of which are beyond our control. The market conditions and the macroeconomic conditions that affect Ambac Financial Group, Inc 24 2023 Form 10-K our business could have a material adverse effect on our ability to secure third-party financing on favorable terms, if at all. If third-party financing is not available when needed, or is available on unfavorable terms, we may be unable to take advantage of business opportunities, respond to competitive pressures or effectively and efficiently manage our balance sheet, any of which could have a material adverse effect on our business, financial condition and results of operations. The composition of the securities in our investment portfolio may expose us to greater risk than before we invested in alternative assets. AAC and Ambac UK allocate a portion of their investment portfolios in below investment grade securities; equities and/or alternative assets; such as hedge funds. Investments in below investment grade securities, equities and alternative assets could expose AAC and/or Ambac UK to greater earnings volatility, increased losses and decreased liquidity in the investment portfolio. Changes in prevailing interest rate levels and market conditions could adversely impact our business results and prospects. Increases in prevailing interest rate levels can adversely affect the value of our investment portfolio and, therefore, our financial strength. In the event that investments must be sold in order to pay claims, to pay debt obligations, to meet collateral posting requirements or to meet other liquidity needs, such likely be sold at discounted prices. investments would Additionally, increasing interest rates would have an adverse impact on the legacy financial guarantee insured portfolio. For example, increasing interest rates could result in higher claim payments in respect of defaulted obligations that bear floating rates of interest. Higher interest rates can also lead to increased credit stress on consumer asset-backed transactions (as the securitized assets supporting a portion of these exposures are floating rate consumer obligations), slower prepayment speeds and resulting “extension risk” relative to such consumer asset- backed transactions in our insured and investment portfolios, and decreased refinancing activity. Decreasing interest rates could result in early terminations of financial guarantee insurance policies in respect of which AAC and Ambac UK are paid on an installment basis and do not receive a termination premium, thus reducing premium earned for these transactions. Decreases in prevailing interest rates may also limit growth of, or reduce, investment income and may increase collateral requirements related to AAC's residual legacy customer interest rate swap portfolio. Our investment portfolio may also be adversely affected by credit rating downgrades, ABS and RMBS prepayment speeds, foreign exchange movements, spread volatility, and credit losses. Our risk to changes in interest rates and market conditions could be magnified in the event that the US or UK were to enter into an economic recession. While interest rates may decline during a recession, credit and liquidity risks would be expected to increase which may cause us to experience losses in our investment portfolios and insured portfolios. These losses may have a material adverse affect on our results of operations and financial condition, particularly if any economic rescission were prolonged. Item 1B. Unresolved Staff Comments — No matters require disclosure. Item 1C. Cybersecurity. The Company is exposed to diverse cybersecurity risks that have the potential to significantly impact our business operations, financial standing, and reputation. We seek to identify, assess, and manage these risks, with the aim of safeguarding our critical systems and information, and employ a documented process to respond in the event of a cybersecurity incident. This approach includes regular evaluations of our information systems and and potential infrastructure weaknesses through the use of system monitoring tools, as well as monitoring industry trends, threat intelligence, and emerging risks to anticipate and proactively assess potential threats. We engage third-party cybersecurity experts to conduct penetration testing, vulnerability scans, and risk assessments, informed by the NIST (National Institute of Standards and Technology) Cybersecurity Framework guidelines, to increase the likelihood that system risks are identified. identify vulnerabilities to To identify potential risks, Ambac also assesses the security measures of vendors and third-party service providers that have access to the Company’s information systems and sensitive data. Each review involves an initial risk assessment of the provider, and initial and periodic reviews of the provider's cybersecurity program to evaluate security standards, access controls and security measures. The Company generally requires vendors and third party service providers to report to the Company any cybersecurity incidents involving the providers’ systems that could affect the Company, or to have cybersecurity incident notice requirements in their cybersecurity programs. to managing cybersecurity risks Our approach includes implementing cybersecurity measures such as selective use of encryption, firewalls, data loss prevention, security monitoring, endpoint detection and response, anti-spam and anti-phishing email security, and intrusion detection systems to fortify our defenses. We conduct mandatory annual employee cybersecurity training programs and frequent simulated phishing campaigns to enhance cybersecurity knowledge and practices across the organization. Ambac maintains an incident response plan that is updated regularly to respond to changes in the organization, risks and laws. Ambac also conducts an annual test to restore business critical systems and data from back-ups. We have established reporting processes and escalation pathways for our business units and functions to identify, assess and manage potential cybersecurity incidents in a timely manner. Once an incident is identified, the Chief Information Security Officer (“CISO”) (with the assistance of the IT team) will begin the investigation to determine the level of risk of the event and the appropriate response. the Company oversees The Board of Directors of the management of risks from cybersecurity threats through its review of quarterly reports from the CISO on the status of the Company’s cybersecurity preparedness; updates on information systems; and any cybersecurity threats of which management Ambac Financial Group, Inc 25 2023 Form 10-K has become aware. In addition the Board receives periodic cybersecurity awareness training. The Company’s technology staff and CISO conduct weekly meetings, attended regularly by the Chief Operating Officer and Chief Information Officer, to review: (i) implementation of new security measures, (ii) results of existing technical system monitoring tools to identify any potential risk and propose remediation, as necessary; (iii) newly disclosed software patch updates to assess risks and set patch implementation priorities; and (iv) threat intelligence from various organizations, such as the Cybersecurity and Infrastructure Security Agency, to assess risks and suggest security measures, as necessary. Cybersecurity risk is also included in the Company’s Enterprise Risk Management (“ERM”) process that involves senior management and other personnel in the identification, assessment and management of a broad range of risks (including cybersecurity risks) that could affect the Company’s ability to execute on its corporate strategy and fulfill its business objectives. The Company’s Chief Operating Officer and Chief Information Officer provide input and updates to the Enterprise Risk Committee (comprised of members of management) on cybersecurity preparedness and emerging risks. The Enterprise Risk Committee produces the relevant risk management information for executive and senior management and the Board of Directors, which receives ERM updates on a quarterly basis. The Chief Operating Officer and Chief Information Officer are also members of the Company's Disclosure Committee and provide updates on cybersecurity threats and emerging risks to the Disclosure Committee prior to the filing of each quarterly report on Form 10-Q and annual report on Form 10-K. The Company’s Chief Information Officer and CISO bring over 35 years of combined experience in the technology and cybersecurity space. The Chief Information Officer has served as a chief information officer and chief technology officer of both private and public institutions for the past 10 years and was responsible for the IT operations and cybersecurity practices of those institutions. The CISO is a certified cybersecurity professional and technologist. He holds an active ISO/ANSI- accredited cybersecurity certification and has experience managing industries, security programs across multiple including financial services and insurance. Other credentials among Ambac’s IT staff include a Certified Information Systems Security Professional certification and a Masters Degree in cybersecurity risk and management. Ambac and its subsidiaries are subject to various U.S. Federal and state laws and regulations with respect to privacy, data protection and cybersecurity that require financial institutions, including insurance companies and agencies, to safeguard personal and other sensitive information, and may provide for notice of their practices relating to the collection, disclosure and processing of personal information, disclosure of cybersecurity risk management practices, reporting of cybersecurity incidents, and implementation of governance practices. For example, the National Association of Insurance Commissioners (“NAIC”) adopted the NAIC Insurance Data Security Model Law (#668) (“NAIC Model Law”) that creates rules for insurers and other covered entities addressing data security and the investigation and notification of cybersecurity events involving unauthorized access to, or the misuse of, certain nonpublic information. This risk assessment, overseeing includes maintaining an information security program based on third-party service ongoing providers, investigating data breaches and notifying regulators of a cybersecurity event. Legislation based on the NAIC Model Law has been enacted in many states and may be enacted in other states. Certain of our subsidiaries, as insurance companies and agencies licensed in the State of New York, are also required to comply with the New York Department of Financial Services (“NYDFS”) cybersecurity regulation, which establishes requirements for covered financial services institutions to implement a cybersecurity program designed to protect the confidentiality, integrity and availability of information systems of regulated entities, and information stored on those systems. The for imposes a governance cybersecurity program, risk based minimum standards for technology systems for data protection, monitoring and testing, third-party service provider reviews, security incident response and reporting to NYDFS of certain security incidents, annual certifications of regulatory compliance to NYDFS, and other requirements. Recent amendments to the NYDFS cybersecurity regulation impose additional security requirements and new governance obligations. framework regulation The California Consumer Privacy Act, went into effect in January 2020, and provides additional privacy rights for California residents, and in November 2020, California further expanded privacy rights for California residents by enacting the California Privacy Rights Act, which became effective January 1, 2023. Several other similar comprehensive privacy laws. We anticipate federal and state regulators to continue to enact legislation related to privacy and cybersecurity, which may require additional compliance investments and changes to policies, procedures and operations. states have enacted The federal Health Insurance Portability and Accountability Act of 1996 and its implementing regulations (“HIPAA”) impose minimum standards on covered entities, such as health insurers, for the privacy and security of protected health information (“PHI”). The Health Information Technology for Economic and Clinical Health Act, enacted in 2009 (“HITECH”) provides for the extension of certain privacy and security provisions of HIPAA to business associates of covered entities that handle electronic PHI. Xchange specializes in accident and health insurance and is a business associate of the health insurers carriers it partners with, making it subject to compliance with the provisions of HITECH and HIPAA applicable to business associates. Item 2. Properties The executive office of Ambac is located at One World Trade Center, New York, New York 10007, and consists of 46,927 square feet of office space, under a sublease agreement that expires in January 2030. Ambac continues to hold a lease at One State Street Plaza, New York that expires in December 2029 (25,871 square feet) that has been sublet through its expiration date. Operations of each of our segments are carried out either in our executive office at One World Trade Center or in other leased offices under operating leases in New Jersey, New York, Indiana and London England. The lease terms typically do not exceed ten years in length.

AFG does not have any commitment or other obligation to provide capital or liquidity to AAC, whose financial guarantee business has been in run-off since 2008. As of December 31, 2023 and 2022, AFG's stand alone net assets, excluding its equity investments in subsidiaries, were $211 and $223, respectively. December 31, 2023 2022 Cash and short-term investments $ 156 $ 178 Other investments (1) Other net assets Total 32 23 28 17 $ 211 $ 223 (1) Includes strategic minority investments in insurance services businesses of $26. The decrease in AFG net assets, excluding its equity investments in subsidiaries, during 2023 was driven by operating expenses, capital contributions to subsidiaries, the acquisition of Riverton Insurance Agency and share repurchases, partially offset by interest income and distributions from subsidiaries. AFG's subsidiaries/businesses are divided into three segments, the key value metrics of which are summarized below along with other recent developments.

Banking Sector Crisis of 2023 The collapse of several banks in early 2023 precipitated a sudden loss of confidence in the banking system, prompting bank runs and the U.S. government to provide direct support to failed banks and, through an expansive emergency lending program, the system more broadly. In the U.S., this crisis was in part a consequence of rising interest rates, resulting in large declines in the market value of U.S. Treasury and government- backed debt held by banking institutions. The risk of additional bank financial stress and/or failures due to asset-liability mismatches or other risks, such as outsized exposure to commercial real estate, remains. Despite actions by government agencies and regulators to mitigate the consequences of these bank failures by providing liquidity and guaranteeing uninsured deposits, there is no guarantee that they will provide similar support in the event of additional bank failures. In Europe, regulators stepped in to facilitate mergers of stressed banks into more stable institutions. The ability or willingness of healthy banks to merge with stressed banks in the future is also subject to significant uncertainty. Ambac's cash balances held at banks was $27 as of December 31, 2023 and $42 as of December 31, 2022. Substantially all of these cash balances were uninsured as of December 31, 2023 and December 31, 2022 because they either (i) exceeded the two hundred and fifty thousand FDIC insurance limit or (ii) were held in foreign banks. These cash balances were held primarily with Ambac's main operating banks which are large money center and/or global banks. Ambac actively manages its cash balances to limit bank risk and to enhance yield by transferring most of its funds to government and prime money market funds. Included in the cash balances above is $16 of cash of companies Ambac has acquired within its insurance distribution businesses that are held in regional banks. The management of these is under balances and consideration as part of Ambac's ongoing integration of these acquired businesses. In addition, cash balances held by variable interest entities ("VIEs") that are consolidated in Ambac's financial statements as a result of Ambac's financial guarantees totaled $246 and $17 as of December 31, 2023 and 2022, respectively. These amounts relate primarily to cash collateral posted against derivative assets and reserve balances maintained the associated bank exposure Ambac Financial Group, Inc 29 2023 Form 10-K under the VIEs' governing documents and are not directly managed by Ambac. CRITICAL ACCOUNTING POLICIES AND ESTIMATES Ambac also has exposure to banks through its fixed maturity investment portfolio totaling $169 and $119 as of December 31, 2023 and December 31, 2022, respectively. All of these investments are managed by third-party asset management firms which follow single and sector risk limits established by Ambac. The average rating of our fixed income investment in banks was A- as of December 31, 2023. Financial Statement Impact of Foreign Currency: The impact of foreign currency as reported in Ambac's Consolidated Statement of Total Comprehensive Income (Loss) for the years ended December 31, 2023 and 2022 included the following: ($ in millions) December 31, Net income (1) Gain (losses) on foreign currency translation (net of tax) Unrealized gains (losses) on non-functional currency available-for-sale securities (net of tax) 2023 2022 $ (3) $ 11 40 (6) (85) 11 Impact on total comprehensive income (loss) $ 31 $ (63) (1) A portion of Ambac UK's, and to a lesser extent AAC's, assets and liabilities are denominated in currencies other than its functional currency and accordingly, we recognized net foreign currency transaction gains/(losses) as a result of changes to foreign currency rates through our Consolidated Statement of Total Comprehensive Income (Loss). Refer to Note 2. Basis of Presentation and Significant Accounting Policies to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K for further details on transaction gains and losses. Future changes to currency rates, may adversely affect our financial results. Refer to Part II, Item 7A "Quantitative and Qualitative Disclosures about Market Risk" further information on the impact of future currency rate changes on Ambac's financial instruments. for SEC Proposed Rules on Climate Related Information On March 21, 2022, the Securities and Exchange Commission (“SEC”) proposed rule amendments that would require public companies to include certain climate-related information in their periodic reports and registration statements, including oversight and governance, material impacts (operational and financial), risk identification and management, and Scope 1, 2 and 3 emissions (the “Proposed Rule”). For accelerated filers, such as Ambac, the Scope 1 and 2 emissions disclosures would require attestation from a third party. These new requirements, if adopted, would at the earliest take effect in fiscal year 2024 and begin to apply to SEC filings in 2025. Final climate disclosure rules have not yet been issued, however the rulemaking agendas for U.S. agencies released in December 2023 indicate the SEC is targeting April 2024 for finalization. Ambac has reviewed the Proposed Rule and will reassess our related compliance obligations and other effects on our operations when the final rule is issued. Ambac's Consolidated Financial Statements have been prepared in accordance with GAAP. This section highlights accounting estimates management views as critical because they are most important to the portrayal of the Company's financial condition; and require management to make difficult and subjective judgments regarding matters that are inherently uncertain and subject to change. These estimates are evaluated on an on-going basis considering historical developments, political events, market conditions, industry trends and other information. There can be no assurance that actual results will conform to estimates and that reported results of operations will not be materially adversely affected by the need to make future accounting adjustments to reflect changes in these estimates from time to time. Management has identified the following critical accounting policies and estimates: (i) valuation of financial guarantee loss and loss adjustment expense reserves, (ii) valuation of certain financial instruments and (iii) valuation of deferred tax assets. Management has discussed each of these critical accounting policies and estimates with the Audit Committee, including the reasons why they are considered critical and how current and those determinations. anticipated Additional information about these policies can be found in Note 2. Basis of Presentation and Significant Accounting Policies to the Consolidated Financial Statements included in Part II, Item 8 in this Form 10-K. future events impact Valuation of Financial Guarantee Losses and Loss Expense Subrogation Recoverables) (including Reserves The loss and loss adjustment expense reserves and subrogation recoverable assets (collectively defined as "loss reserves") discussed in this section relate solely to Ambac’s financial guarantee insurance policies issued to beneficiaries. A loss reserve is recorded on the balance sheet on a policy-by-policy basis at the present value ("PV") of expected net claim cash outflows or expected net recovery cash inflows, discounted at risk-free rates. The estimate for future net cash flows considers the likelihood of all possible outcomes that may occur from missed principal and/or interest payments on the insured obligation. This estimate also considers future recoveries related to remediation strategies and other contractual or subrogation- related cash flows. The evaluation process for expected future net cash flows is subject to estimates and judgments regarding the probability of default by the issuer of the insured security, the probability of negotiation or settlement outcomes (which may include commutation, litigation and other settlements, and/or a refinancing), the probability of restructuring outcomes (which may include payment moratoriums, debt haircuts and/or subsequent recoveries) and the expected loss severity of credits for each insurance contract. As the probability of default for an individual credit increases and/or the severity of loss given a default increases, our loss reserve for that insured obligation will also increase. Political, economic, environmental, credit or other unforeseen events Ambac Financial Group, Inc 30 2023 Form 10-K could have an adverse impact on default probabilities and loss severities. The loss reserves for many transactions are derived from the issuer’s creditworthiness. For public finance issuers, loss reserves will consider not only creditworthiness, but also political dynamics and economic status and prospects. The loss reserves for transactions which have no direct issuer support, such as most structured finance exposures, including RMBS and student loan exposures, are derived from the default activity and the estimated loss given default of the underlying collateral supporting the transactions. In addition, many transactions have a combination of issuer/entity and collateral support. Loss reserves reflect our assessment of the transaction’s overall structure, support and expected performance. Loss reserve volatility will be a direct result of the credit performance of our insured portfolio, including the number, size, bond types and quality of credits included in our loss reserves; our ability to execute workout strategies and commutations; economic and market conditions; and management's judgments with regards to the current performance and future developments within the insured portfolio. The number and severity of credits included in our loss reserves depend to a large extent on transaction specific attributes, but will generally increase during periods of economic stress and decline during periods of economic prosperity. Reinsurance contracts may mitigate future loss reserve volatility. While Ambac currently has minimal exposure ceded to reinsurers on financial guarantee credits with loss reserves, the existing reinsurance contracts would reduce future volatility to the extent loss reserves are established on those risks ceded to reinsurers. Loss reserve volatility will also be materially impacted by changes in interest rates from period to period. The table below indicates the gross par outstanding and gross loss reserves (including loss expenses) related to policies in Ambac’s Financial Guarantee loss and loss adjustment expense reserves at December 31, 2023 and 2022: Gross Loss and Loss Adjustment Expense Reserves (1) (3) (4) Gross Par Outstanding (1) (2) $ 1,860 $ $ $ 834 1,144 — 3,838 2,050 1,215 782 — $ 4,047 497 66 (8) 4 559 358 75 3 8 444 December 31, 2023 Structured Finance Domestic Public Finance Other Loss expenses Totals December 31, 2022 Structured Finance Domestic Public Finance Other Loss expenses Totals (1) Ceded par outstanding on policies with loss reserves and ceded loss and loss adjustment expense reserves are $362 and $30 respectively, at December 31, 2023, and $472 and $33, respectively at December 31, 2022. Ceded loss and loss adjustment expense reserves are included in Reinsurance recoverable on paid and unpaid losses. (2) Gross Par Outstanding includes capital appreciation bonds, which are reported at the par amount at the time of issuance of the insurance policy as opposed to the current accreted value of the bond. (3) Loss and Loss Adjustment Expense reserves at December 31, 2023, of $559 are included in the balance sheet in the following line items: Loss and loss adjustment expense reserves: $696 and Subrogation recoverable: $137. Loss and Loss Adjustment Expense reserves at December 31, 2022, of $444 are included in the balance sheet in the following line items: Loss and loss adjustment expense reserves: $715 and Subrogation recoverable: $271. (4) Ambac records as a component of its loss and loss adjustment expense reserves, estimated recoveries related to securitized loans in RMBS transactions that breached certain representations and warranties. Ambac has recorded gross estimated recoveries of $0 and $140 at December 31, 2023 and 2022, respectively. See the Balance Sheet section of this Management's Discussion and Analysis of Financial Condition and Results of Operations below for a discussion on the reasons for changes to Gross Loss and Loss Adjustment Expense Reserves during 2023. See Note 2. Basis of Presentation and Significant Accounting Policies to the Consolidated Financial Statements, included in Part II, Item 8 in this Annual Report on Form 10-K for a description of the cash flow and statistical methodologies used to develop loss reserves. The majority of our large loss reserves utilize the cash flow method of reserving. Various cash flow scenarios are developed to represent the range of possible outcomes and resultant future claim payments and timing. Scenarios and probabilities of each are adjusted regularly to reflect changes in status, outlook and our analysis and views. the cash flow Significant assumptions and related probabilities, and there can be no certainty that the scenarios or probabilities will not deviate materially from ultimate outcomes. to develop judgment is used • In some cases, such as RMBS and student loans, cash flow projections include the modeling of a securitization's cash flows to determine the resources available to pay debt service on our insured obligations. During the first quarter of 2023, Ambac revised the model it uses to project RMBS collateral losses considering the seasoning of our RMBS exposure and management’s view that the most relevant determinant of prospective collateral performance is Individual home price borrower payment status. less a critical appreciation/depreciation has become determinant of performance considering the general appreciation in home values over the past few years as well as the impact of loan modifications. The average estimated loan-to-values of the collateral related to insured exposures have declined to under 50% from peaks above 110%. Key assumptions impacting student loan cash flow models include projected loan defaults, recoveries and interest rates. During the second quarter of 2023, we revised our approach to projecting future defaults to both reflect the student loan collateral's seasoning and generally stable performance. • In other cases, such as many public finance exposures, we consider the issuer's overall ability and willingness to pay as it relates to the existing fiscal, economic, legal, restructuring and/or political framework relevant to a particular exposure or group of exposures. We then develop multiple scenarios where issuer debt service is Ambac Financial Group, Inc 31 2023 Form 10-K paid, missed and/or haircut with claims paid then factor in any projected recovery amount (and potential variability of the recovery amount) and the timing thereof. There is no certainty our assumptions as to scenarios or probabilities will not be subject to material changes as developments occur. strategies. Remediation • In estimating loss reserves, we may also incorporate the potential outcome of scenarios which represent remediation scenarios could include (i) a potential refinancing of the transaction by the issuer; (ii) the issuer’s ability to redeem outstanding securities at a discount, thereby increasing the structure’s ability to absorb future losses; and (iii) our ability to terminate, restructure or commute the policy in whole or in part. The remediation scenarios and the related probabilities of occurrence vary by policy depending on ongoing and expected discussions and negotiations with issuers and/or investors. In addition to commutation negotiations that are underway with various counterparties in various forms, our reserve estimates may also include scenarios which incorporate our ability and/or expectation to commute additional exposure with other counterparties. Valuation of Certain Financial Instruments The Fair Value Measurement Topic of the ASC requires financial instruments to be classified within a three-level fair value hierarchy. The fair value hierarchy, the financial instruments classified within each level, our valuation methods, inputs, assumptions and the review and validation procedures over quoted and modeled pricing are further detailed in Note 5. Fair Value Measurements the Consolidated Financial to Statements included in Part II, Item 8 in this Annual Report on Form 10-K. The level of judgment in estimating fair value is largely dependent on the amount of observable market information available to fair value a financial instrument, which is also determinative of where the financial instrument is classified in the fair value hierarchy. Level 3 instruments are valued using models which use one or more significant inputs or value drivers that are unobservable and therefore require significant judgment. Level 3 financial instruments which are material include certain invested assets, uncollateralized interest rate swaps and investments and loan receivables of consolidated VIEs. Model- derived valuations of Level 3 financial instruments incorporate estimates of the effects of Ambac's own credit risk and/or counterparty credit risk, which can be complex and judgmental. Furthermore, Level 3 investments and loan receivables of consolidated VIEs incorporate estimates of Ambac's financial guarantee cash flows, including future premiums and losses. Such cash regarding prepayments of VIE debt, loss probabilities and loss severities, all of which are inherently uncertain. flow estimates judgments require All models and related assumptions are continuously re- evaluated by management and enhanced, as appropriate, based on improvements in information and modeling techniques. The re-evaluation process includes a quarterly meeting of senior Finance personnel to review and approve changes to models and key assumptions. As a result of the significant judgment for the above-described instruments, the actual trade value of the financial instrument in the market, or exit value of the financial instrument owned by Ambac, may be significantly different from its recorded fair value. Valuation of Deferred Tax Assets judgment Our provision for taxes is based on our income, statutory tax rates and tax planning opportunities available to us in the jurisdictions in which we operate. Tax laws are complex and subject to different interpretations by the taxpayer and respective is taxing authorities. Significant governmental required in determining our tax expense and in evaluating our tax positions. We review our tax positions quarterly and adjust the balances as new information becomes available. Deferred tax assets arise because of temporary differences between the financial reporting and tax bases of assets and liabilities, as well as from net operating loss ("NOL"). More specifically, deferred tax assets represent a future tax benefit that results from losses recorded under GAAP in a current period which are only deductible for tax purposes in future periods, future GAAP income that will not result in corresponding taxable income and NOL carry forwards. Valuation allowances are established to reduce deferred tax assets to an amount that “more likely than not” will be realized. Management considers all available evidence, both positive and negative, when determining whether to establish and/or maintain a valuation allowance against deferred tax assets, with significant weight given to evidence that can be objectively verified. Positive evidence includes reduced potential for material loss as a result of settling RMBS representation and warranty litigation and resolving exposure to Puerto Rico, Everspan's receipt of an 'A-'' Financial Strength Rating from AM Best, the launch of a specialty program property and casualty insurance business, AFG's acquisition of majority interests in MGA/U businesses and AAC's reduction of material amounts of debt. Negative evidence includes Specialty Property and Casualty Insurance and Insurance Distribution businesses not yet at scale, the Legacy Financial Guarantee Insurance business remaining in run-off, and material amounts of debt at AAC. The level of deferred tax asset recognition is influenced by management’s assessment of future expected taxable income, which depends on the existence of sufficient taxable income within the carry forward periods available under the tax law. As a result of the above-described risks and uncertainties associated with future operating results, management believes it is more likely than not that the Company will not generate sufficient taxable income to recover part or all the U.S. federal deferred tax asset and therefore has a full valuation allowance. To the extent such risks and uncertainties are resolved, Ambac may have the ability to establish a history of making reliable estimates of future income which could ultimately result in a reduction to the deferred tax asset valuation allowance. See Note 16. the Consolidated Financial to Statements, included in Part II, Item 8 in this Annual Report on Form 10-K for additional information on the Company's deferred income taxes. Income Taxes Ambac Financial Group, Inc 32 2023 Form 10-K FINANCIAL GUARANTEES IN FORCE Financial guarantee products were sold in three principal markets: U.S. public finance, U.S. structured finance and international finance. Net par exposures within the U.S. public finance market include capital appreciation bonds which are reported at the par amount at the time of issuance of the insurance policy as opposed to the current accreted value of the bonds. Guaranteed net par outstanding includes the exposures of policies (“VIEs”) consolidated in accordance with the Consolidation Topic of the ASC. Guaranteed net par outstanding excludes the exposures of policies that insure bonds which have been refunded, pre- refunded or synthetically commuted. insuring variable interest entities AAC's Risk Management Group focuses on the implementation and execution of risk reduction, defeasance and loss recovery strategies. Analysts evaluate the estimated timing and severity of projected policy claims as well as the potential impact of loss mitigation or remediation strategies in order to target and thereof, for commutation, prioritize policies, or portions reinsurance, refinancing, restructuring or other risk reduction strategies. For targeted policies, analysts will engage with issuers, bondholders and other economic stakeholders to negotiate, structure and execute such strategies. During 2023, Ambac completed risk reduction transactions equating to $2,419, including a quota share reinsurance cession of $2,069 insured par, consisting primarily of military housing risk of $1,958. The following table provides a comparison of total, adversely classified ("ACC") and watch list (as described in Note 2. Basis of Presentation and Significant Accounting Policies to the Consolidated Financial Statements included in Part II, Item 8 of this Annual Report on Form 10-K) credit net par outstanding in the insured portfolio at December 31, 2023 and 2022.

The following table provides a breakdown of guaranteed net par outstanding by market at December 31, 2023 and 2022. December 31, Public Finance (1) Structured Finance International Finance 2023 2022 $ 7,562 $ 10,547 3,315 8,664 3,612 8,454 Total net par outstanding $ 19,541 $ 22,613 (1) Includes $3,371 and $5,400 of Military Housing net par outstanding at December 31, 2023 and 2022, respectively. Below we discuss the significant exposures in our insured portfolio relating to each of the three markets. See Note 6. Financial Guarantees in Force to the Consolidated Financial Statements, included in Part II, Item 8 in this Annual Report on Form 10-K for exposures by bond type. U.S. Public Finance Insured Portfolio AAC’s portfolio of U.S. public finance exposures totaled $7,562 in net par outstanding, representing 39% of Ambac’s net par outstanding as of December 31, 2023, and a 28% reduction from the amount outstanding at December 31, 2022. This reduction resulted from active de-risking (primarily from the above- mentioned reinsurance cession of $2,069 of insured par), scheduled paydowns, and early terminations (calls, refundings and pre-refundings). Ambac’s U.S. public finance portfolio consists of municipal bonds such as general obligation, revenue, and lease and tax-backed obligations of state and local government entities, and also includes several non-municipal types of bonds, such as financings with public and private elements, which generally finance infrastructure, housing and other public interests, the largest sector of which is U.S. military housing which accounts for approximately 45% of AAC's U.S. Public Finance Insured Portfolio. Municipal Bonds Municipal bonds are generally supported directly or indirectly by the issuer’s taxing authority or by public sector fees and assessments which may or may not be specifically pledged. Risk factors in these transactions derive from the municipal issuer, including its fiscal management, politics, and economic position, as well as its ability and willingness to continue to pay its debt service. Municipal bankruptcies and similar proceedings, while still relatively uncommon, have occurred, exposing Ambac to the risk of liquidity claims and ultimate losses if issuers cannot successfully adjust their liabilities without impairing creditors. Non-Municipal Bonds Public/private transactions are generally structured to achieve their targeted public interest objective without direct support from the public sector. Some examples of this type of financing include affordable housing, private education, and privatized military housing. Protections within these financings provided to Ambac usually include the strength of the financed asset’s essentiality and public purpose and may include financial covenants, collateral and control rights. Risk factors include financial underperformance, event risk and a shift in the asset’s mission or essentiality. Military Housing Bonds AAC's largest concentration of non-municipal bonds is U.S. military housing. Ambac insures $3,371 net par of privatized military housing debt. The debt was issued to finance the construction and/or renovation of housing units for military personnel and their families on domestic U.S. military bases. Debt service is not directly paid or guaranteed by the U.S. Government. Rather, the bonds are serviced from the cash flow generated in most cases by rental payments deposited by the military directly into lockbox accounts as part of each service personnel’s Basic Allowance for Housing (BAH). In typically small percentages, rental payments can also come from civilians, including retired service personnel and US Department of Defense contractors living on a particular base. Collateral for these transactions includes the BAH payments as well as an interest in the ground lease. Risk factors affecting these Ambac Financial Group, Inc 33 2023 Form 10-K transactions include ongoing base essentiality, military deployments, the U.S. government’s commitment to fund the BAH, marketability/attractiveness of the on-base housing units versus off-base housing, construction completion, environmental remediation, natural disasters, excessive utility and other operating costs and housing management. As of December 31, 2023, privatized military housing represented approximately 17% of net par outstanding as compared to 24% as of December 31, 2022. Ambac's privatized military housing exposure decreased from 2022 as a result of the above-mentioned reinsurance cession. U.S. Structured Finance Portfolio Ambac’s portfolio of U.S. structured finance exposures is $3,315 in net par outstanding, representing 17% of Ambac’s net par outstanding as of December 31, 2023, and an 8% reduction from the amount outstanding at December 31, 2022. This reduction in exposure was primarily related to (i) RMBS policies, which continued to prepay as well as incur claims and (ii) scheduled paydowns. Current insured exposures primarily include securitizations of mortgage loans, home equity loans and student loans, and investor-owned utilities in each case where the majority of the underlying collateral risk is situated in the United States. At December 31, 2023, RMBS represented approximately 9% of net par outstanding. Structured finance securitization exposures generally entail three forms of risk: (i) asset risk, which relates to the amount and quality of the underlying assets; (ii) structural risk, which relates to the extent to which the transaction’s legal structure and credit support provide protection from loss; and (iii) servicer risk, which is the risk that poor performance at the servicer or manager level contributes to a decline in cash flow available to the transaction. AAC seeks to mitigate and manage these risks through its risk management practices. International Finance Insured Portfolio Ambac’s portfolio of international finance insured exposures is $8,664 in net par outstanding, representing 44% of Ambac’s net par outstanding as of December 31, 2023, and a 2% increase from the amount outstanding at December 31, 2022. This increase in exposure was primarily the result of a weakening of the US dollar versus the British pound and the Euro, partially offset by de-risking activity. Ambac’s international finance insured exposures include a wide array of obligations in the international markets, including infrastructure financings, utility obligations, whole business securitizations (e.g., securitizations of substantially all of the operating assets of a corporation) and sub-sovereign credits. When underwriting transactions in the international markets, Ambac considered the specific risks related to the particular country and region that could impact the credit of the issuer. These risks include the legal and political environment, capital markets dynamics, foreign exchange issues and the degree of governmental support. Ambac continues to assess these risks, as well as emerging risks, through its ongoing risk management. Ambac's international net par exposures are principally in the United Kingdom ($7,502); however, we also have exposures with credit risk based in various EU member states, including Austria, France, Germany and Italy ($895). At December 31, 2023, sub-sovereign and investor-owned and public utilities represented approximately 22% and 15% (Electric 5%, Gas 5% and Water 5%) of total net par outstanding, respectively. Ambac has no insured exposure related to emerging markets. Ambac UK, which is regulated in the United Kingdom (“UK”), was AAC’s primary vehicle for directly issuing financial guarantee policies in the UK and the European Union with $8,397 net par outstanding at December 31, 2023 (represents approximately 97% of Ambac's international net par outstanding). The portfolio of insured exposures underwritten by Ambac UK is financially supported exclusively by the assets of Ambac UK and no capital support arrangements are in place with any other Ambac affiliate.

Ambac credit ratings are subject to revision at any time and do not constitute investment advice. BIG denotes credits deemed below investment grade. Net par related to the top ten exposures reduced $25 from December 31, 2022. Exposures are impacted by commutations, changes in foreign exchange rates ($283 increase during 2023), certain indexation rates linked to inflation measures in the United Kingdom (RPI) and scheduled and unscheduled paydowns. As a result of recent increases in inflation, such indexation-linked exposures have increased at a faster pace than they have historically. The concentration of net par amongst the top ten (as a percentage of net par outstanding) increased to 31% at December 31, 2023, from 27% at December 31, 2022. Excluding the top ten exposures, the remaining insured portfolio of financial guarantees has an average net par outstanding of $28 per single risk, with insured exposures ranging up to $307 and a median net par outstanding of $5. Additional Insured Portfolio Information Average Life of Insured Portfolio Ambac estimates that the average life of its guarantees on par in force at December 31, 2023, is approximately 10 years. The average life is determined by applying a weighted average calculation, using the remaining years to expected maturity of each guaranteed bond, and weighting them on the basis of the remaining net par guaranteed. Except for RMBS policies, no assumptions are made for non-contractual reductions, refundings or terminations of insured issues. RMBS policies incorporate assumptions on expected prepayments over the remaining life of the insured obligation.

Below investment grade exposures could increase as a relative proportion of the guarantee portfolio given that Ambac hasn't written any new financial guarantee business since 2008 and stressed borrowers generally have less ability to prepay or refinance their debt. Accordingly, due to these and other factors, it is not unreasonable to expect the proportion of below investment grade exposure in the guarantee portfolio to continue to increase in the future.

As a primary financial guarantor, AAC is required to honor its obligations to its policyholders whether or not its reinsurers perform their obligations under these reinsurance agreements. AAC's reinsurers all have applicable ratings of A or better. As of December 31, 2023, the aggregate amount of insured par ceded by AAC to reinsurers under reinsurance agreements was $6,464, with the largest reinsurer accounting for $2,766 or 10.6% of gross par outstanding at December 31, 2023.

Net income attributable to common stockholders for the year ended December 31, 2023, was $4 compared to a net income attributable to common stockholders of $522 for the year ended December 31, 2022. The net income variance was primarily driven by: (i) a lower loss and loss adjustment expenses benefit, (ii) a litigation recovery in 2022, (iii) 2022 gains on derivative contracts, and (iv) 2022 net gains on extinguishment of debt, partially offset by higher returns from the investment portfolio and lower interest expense.

This reinsurance cession had an adverse impact on net premiums earned of approximately $2. • As of December 6, 2022, all AAC-insured Puerto Rico obligations were restructured under PROMESA via court- approved plans of adjustment or qualifying modifications. As a result of these restructurings, Ambac's 2022 consolidated financial results included a net benefit of $180 in losses and gains of $37 on the consolidation of newly established variable interest entities; partially offset by net losses of $23 from sales and changes to the fair value of securities received by AAC in the restructurings and losses of $17 on the VIEs after initial consolidation. • On October 6, 2022, AAC entered into a Settlement Agreement and Release with Bank of America Corporation and certain affiliates thereof (the "BOA Parties") whereby the parties settled all RMBS litigation brought by AAC against the BOA Parties and AAC received $1,840 (the "BOA Settlement Payment"). On December 29, 2022, AAC entered into a Settlement Agreement and Release with Nomura Credit & Capital, Inc. ("Nomura") whereby the parties settled all RMBS litigation brought by AAC Ambac Financial Group, Inc 37 2023 Form 10-K against Nomura and AAC received $140 on January 3, 2023. AAC used the proceeds from these settlements (net of reinsurance) plus approximately $6 of cash on hand to fully redeem all debt obligations secured by the net proceeds of litigations brought by AAC against RMBS sponsors. The settlements with the BOA Parties and Nomura brought to closure all of AAC's legacy litigation against RMBS sponsors. See Note 1. Background and Business Description in Part II, Item 8 in this Annual Report on Form 10-K for further information. During 2022, AAC recorded a gain of $123 million in loss and loss adjustment expenses and litigation recoveries of $126, offset by net realized losses on extinguishment of debt of $53 related to the above-mentioned settlement agreements. Interest expense was significantly reduced in 2023 as a result of these settlements. The following paragraphs describe the consolidated results of operations of Ambac and its subsidiaries for 2023 and 2022. Gross Premiums Written. Gross premiums written increased $161 for the year ended December 31, 2023, compared to the same periods in the prior year, as shown by segment below. Year Ended December 31, 2023 2022 2021 Legacy Financial Guaranty Insurance $ 15 $ (20) $ (11) Specialty Property & Casualty Insurance Total 273 146 $ 288 $ 127 $ 13 2 Legacy Financial Guarantee Insurance gross premiums written relate to changes in expected and contractual premium cash flows for existing financial guarantees in force. Specialty P&C growth is primarily driven by the number of active programs and their size as of December 31, 2023, we have twenty-three programs with nineteen MGA/Us. Net Premiums Written. Net premiums written increased $22 for the year ended December 31, 2023 compared to the year ended December 31, 2022, as shown by segment below: Year Ended December 31, 2023 2022 2021 Legacy Financial Guaranty Insurance $ (35) $ (6) $ (35) Specialty Property & Casualty Insurance Total 80 29 $ 44 $ 23 $ 3 (33) Legacy Financial Guarantee Insurance net premiums written relate to changes in expected and contractual premium cash flows for existing financial guarantees in force, and reinsurance cessions in 2023 and 2021. Specialty P&C growth is primarily driven by the number of active programs and their size as of December 31, 2023, in addition to the impact of two assumed reinsurance transactions executed during 2023. Net Premiums Earned. Net premiums earned for the year ended December 31, 2023 increased by $22 or 38% as compared to net premiums earned for the year ended December 31, 2022, as shown below. Year Ended December 31, 2023 2022 2021 Legacy Financial Guaranty Insurance $ 26 $ 42 $ Specialty Property and Casualty Insurance Total 52 14 78 $ 56 $ 46 1 47 reinsurance The reduction in the Legacy Financial Guarantee Insurance segment was primarily due to de-risking activities, including the 2023 the 2022 Puerto Rico restructurings, and run-off of the insured portfolio. The increase in Specialty Property and Casualty Insurance net premiums earned was driven by the growth in net premiums written. transaction, Commission Income and Commission Expense. Commission income was $51 compared to $31, for the years ended December 31, 2023 and 2022. Commissions include both base and profit sharing commissions from Cirrata Group companies in the Insurance Distribution segment. The increase was driven by organic growth in premiums placed as well as the acquisition of All Trans and Capacity Marine in November of 2022 and Riverton in August of 2023. Commission expense will largely track changes in gross commission. For the year ended December 31, 2023 commission expense was $29 compared to $18 for the year ended December 31, 2022, representing approximately 57% of commission income in both periods. Program Fees. Program fee revenues were $8 compared $3 for the years December 31, 2023 and 2022, respectively. Program fee revenues represent the recognition of ceding commissions in excess of direct acquisition costs received from reinsurers and minimum fees received from MGA/Us until related programs reach certain levels of premium ceded. Program fees are charged as a percentage of premiums ceded to reinsurers as a component of total ceding commissions. Net Investment Income. Net investment income primarily consists of interest and net discount accretion on fixed maturity securities classified as available-for-sale, interest and changes in fair value of fixed maturity securities classified as trading, and net gains (losses) on pooled investment funds which include changes in fair value of the funds' net assets. Fixed maturity securities include investments in Ambac-insured securities that are made opportunistically based on their risk/reward and asset- liability management characteristics. Investments in pooled investment funds and certain other investments are either classified as trading securities with changes in fair value recognized in earnings or are reported under the equity method. These funds and other investments are reported in Other investments on the Consolidated Balance Sheets. For further information about investment funds held, refer to Note 4. Investments to the Consolidated Financial Statements, included in Part II, Item 8 in this Annual Report on Form 10-K. Net investment income for the periods presented were driven by the Legacy Financial Guarantee Insurance segment; other segments' results were not significant.

Pooled fund investments produced a gain of $40, an increase of $66 from 2022, driven by improved performance in all fund categories even with a lower allocation to funds overall. The largest increases were in hedge funds, equities and high-yield and leverage loan funds. Investments in pooled funds may be volatile, but are generally expected to produce higher returns than traditional fixed maturity investments. Gains on securities received in the Puerto Rico restructurings, which are classified as trading, were $7 in 2023, compared to a loss of $23 in 2022. • Net investment income from available-for-sales securities other than Ambac-insured securities increased $27 in 2023, compared to the prior year, due to higher portfolio yields. • Investment income from Ambac-insured securities was flat compared to 2022. Higher average holdings of Ambac- insured RMBS and student loans in 2023 offset the impact of the 2022 settlements of Puerto Rico bonds and the redemption of Sitka Senior Secured Notes (as defined in Note 12. Long-Term Debt to the Consolidated Financial Statements included in Part II, Item 8 in the Annual Report on Form 10-K) held in the portfolio in 2022. Investment Gains Net including Impairments. The following table provides a breakdown of net investment gains, for the periods presented: (Losses), Year Ended December 31, 2023 2022 2021 Net realized gains on securities sold or called $ (4) $ Net foreign exchange gains (losses) Credit impairment Intent / requirement to sell impairments Total net investment gains, including impairments (4) (3) (12) $ 18 14 — — $ (22) $ 31 $ 11 (5) — — 7 Net investment gains (losses) during the year ended December 31, 2023, included impairments of Ambac-insured student loan securities that management intends to sell. Net investment gains during the year ended December 31, 2022, included a recovery of $9 from a class-action settlement relating to certain RMBS securities previously held in the investment portfolio, $4 from the distribution of residual assets of a legacy financial guarantee student loan restructuring vehicle and $5 from the mandatory redemption of Sitka Senior Secured Notes over their amortized cost value. Other net realized gains on securities sold or called in 2023 and 2022 are primarily from sales in connection with routine portfolio management. Refer to Note 2. Basis of Presentation and Significant Accounting Policies the Consolidated Financial Statements located in Part II, Item 8 in this Annual Report on Form 10-K for a description of the Company's policies related to investment impairments. to Net Gains (Losses) on Derivative Contracts. Net gains (losses) on derivative contracts are primarily from the Company's interest rate derivatives portfolio. Into the second quarter of 2023, the interest rate derivatives portfolio was positioned to benefit from rising rates as a partial economic hedge against interest rate exposure in the financial guarantee insurance and investment portfolios. This economic hedge was substantially reduced since September 30, 2022, and was fully removed during the second quarter of 2023. Net gains (losses) on interest rate derivatives reflect mark-to-market gains (losses) in the portfolio caused by increases (declines) in forward interest rates during the periods, the carrying cost of the portfolio, and the impact of counterparty credit adjustments as discussed below. Results from other non-VIE derivatives were not significant to the periods presented. Net losses on interest rate derivatives for the year ended December 31, 2023, were $1, compared to a net gains of $128 for the year ended December 31, 2022. Results for the year ended December 31, 2023, reflect the impacts of interest rate shifts in the early part of 2023 and counterparty credit adjustments as noted below. The net gains in 2022 were driven primarily by the significant rate increase during the year. Counterparty credit adjustments are generally applicable for uncollateralized derivative assets that may not be offset by derivative liabilities under a master netting agreement. In periods when credit spreads are stable, counterparty credit adjustments will generally have a proportionate offsetting impact to gains or losses on derivative assets, relative to fully collateralized assets. In addition to the impact of interest rates on the underlying derivative asset values, in counterparty credit adjustments are driven by movement of credit spreads. Generally, narrowing (widening) of credit spreads will increase (decrease) derivative gains relative to a period of stable credit spreads. Inclusion of counterparty credit adjustments in the valuation of interest rate derivatives resulted in gains (losses) within Net gains (losses) on derivative contracts of $2 and $8 for the years ended December 31, 2023 and 2022, respectively. The lower counterparty credit adjustments for both periods reflected lower underlying asset values with the further impact of credit spread narrowing in 2023 and widening in 2022. the changes Net Realized Gains on Extinguishment of Debt. Net realized gains on extinguishment of debt was $0 for year ended December 31, 2023. Net realized gains on extinguishment of debt was $81 for the year ended December 31, 2022. Gains were recognized due to repurchases of surplus notes below their carrying values, partially offset with losses recognized on the redemption of the Sitka AAC Note (as defined in Note 12.

AAC repurchased $266 million current par of surplus notes from third party holders in 2022. Subject to prevailing market conditions, our internal and regulatory guidelines and approvals, contractual restrictions and OCI’s Run-off Capital Framework, Ambac may continue to opportunistically reduce, redeem, repurchase or otherwise retire its outstanding surplus notes, including through open market redemptions or repurchases, otherwise, and may consider opportunities to exchange securities issued by it from time to time for other securities issued by AFG or AAC. tender offers, repayments, losses attributable including gains or Income (Loss) on Variable Interest Entities. Included within Income (loss) on variable interest entities are income statement amounts relating to LFG-VIEs consolidated under the Consolidation Topic of the ASC as a result of Ambac's variable interest arising from financial guarantees written by Ambac's subsidiaries, to consolidating or deconsolidating LFG-VIEs during the periods reported. Generally, the Company’s consolidated VIEs are entities for which Ambac has provided financial guarantees on all of or a portion of its assets or liabilities. In consolidation, most assets and liabilities of the LFG-VIEs are initially reported at fair value, except for customer contract assets and liabilities which are accounted for under the Revenue from Contracts with Customers Topic of the ASC. The related insurance assets and liabilities are eliminated in consolidation. The amount of LFG- VIE net assets (liabilities) in consolidation incorporate the net positive (negative) future cash flows from (to) the VIEs which are attributable to Ambac’s insurance subsidiaries in the form of financial guarantee insurance premiums, fees and losses. Generally, LFG-VIEs in a net liability position are expected to have some portion of their obligations funded by Ambac’s insurance subsidiaries through insurance claim payments. Differences between the net carrying value of the insurance accounts under the Financial Services— Insurance Topic of the ASC and the carrying value of the consolidated LFG-VIEs' net assets or liabilities are recorded through income at the time of consolidation. Additionally, terminations or other changes to Ambac's financial guarantee insurance policies that impact projected cash flows between a consolidated LFG-VIE and Ambac could result in gains or losses, even in deconsolidation of the LFG-VIE. if such policy changes do not result that remain Income (loss) on variable interest entities was $3 and $21 for the years ended December 31, 2023 and 2022, respectively. Results for the year ended December 31, 2023, were driven primarily by the $4 gain upon consolidation of a VIE for which Ambac UK guarantees the senior debt. Results for the year ended December 31, 2022. related primarily to three VIE trusts created in connection with the Puerto Rico restructurings in 2022. The 2022 gain initial $37 million gain upon consolidation, losses of $9 from changes to fair value of these VIEs' assets, and losses of $7 from these VIEs' interest and other costs. Refer to Note 11. Variable Interest Entities to the Consolidated Financial Statements included in this Annual Report on Form 10-K for further information on the accounting for VIEs. included the Litigation Recoveries. For the year ended December 31, 2022, in connection with the settlement agreement with Bank of included recoveries from America Corporation and certain affiliates, the BOA Settlement litigations for alleged Payment breaches of contractual obligations and fraud by the BOA Parties. Management allocated the BOA Settlement Payment to each of the litigations based on previously developed valuations of each individual litigation. The portion of the BOA Settlement Payment allocated to fraud litigation recoveries has been recorded as a litigation recovery in the Statement of Comprehensive Income (Loss). Losses and Loss Adjustment Expenses (Benefit). Losses and loss adjustment expenses increased $364 for the year ended December 31, 2023, compared to the prior year. Below provides the breakout of loss and loss expenses by segment: Year Ended December 31, Legacy financial guarantee Specialty property and casualty insurance Total 2023 2022 (69) $ (406) $ 37 9 $ (33) $ (396) $ 2021 (89) — (88) $ $ The large variance within legacy financial guarantee was driven by activities in the RMBS portfolio in 2023 and 2022, including the impact of the Settlement Agreements with Bank of America Corporation and certain affiliates thereof and the settlement agreement with Nomura during 2022. Refer to discussion of each segment's results below for further details. General and Administrative Expenses ("G&A").

The increase was primarily due to the following: • Higher compensation costs primarily due to a net increase in staffing from additions in the Specialty Property and Casualty Insurance and Insurance Distribution segments and the impact of performance factor adjustments on incentive compensation expense, partially offset by reductions in staffing in the Legacy Financial Guarantee Insurance segment. • Higher non-compensation costs primarily to increased Legacy Financial Guarantee Insurance segment defensive litigation expenses and costs associated with growth of the Specialty Property and Casualty Insurance and Insurance Distribution businesses. related Intangible Amortization. Insurance intangible amortization was $25 and $44 for the years ended December 31, 2023 and 2022, respectively. The decrease was driven primarily by the timing of de-risking transactions (including Puerto Rico in 2022) and the reduced size of the financial guarantee insured portfolio. Insurance intangible amortization will decline after policies mature or they are de-risked Other intangible amortization was $3 and $3 for the years ended December 31, 2023 and 2022 Ambac Financial Group, Inc 40 2023 Form 10-K relating segment. to acquisitions within the Insurance Distribution Interest Expense.

The decrease in interest expense for the year ended December 31, 2023, compared to the year ended December 31, 2022, reflects the impact of the 2022 redemption of secured notes and purchases of surplus notes as described further under "Debt Redemptions and Extinguishments" in Note 12. Long-term Debt to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K. Surplus note principal and interest payments require the approval of OCI. In May 2023, OCI declined the request of AAC to pay the principal amount of the surplus notes, plus all accrued and unpaid interest thereon, on the then next scheduled payment date of June 7, 2023. As a result, the scheduled payment date for interest, and the scheduled maturity date for payment of principal of the surplus notes was extended until OCI grants approval to make the payment. Interest will accrue, compounded on each anniversary of the original scheduled payment date or scheduled maturity date, on any unpaid principal or interest through the actual date of payment, at 5.1% per annum. Holders of surplus notes will have no rights to enforce the payment of the principal of, or interest on, surplus notes in the absence of OCI approval to pay such amount. The interest on the outstanding surplus notes were accrued for and AAC is accruing interest on the interest amounts following each scheduled payment date. Total accrued and unpaid interest for surplus notes outstanding to third parties was $475 at December 31, 2023. As required by the terms of surplus notes, AAC will continue to seek OCI’s approval to make payments of principal and interest on its surplus notes. OCI’s approval may be granted or denied in OCI’s sole discretion. Since the issuance of the surplus notes in 2010, OCI has declined to approve regular payments of interest on surplus notes, although the OCI has permitted two exceptional payments. Ambac can provide no assurance as to when or if surplus note principal and interest payments will be made. Provision for Income Taxes. The provision for income taxes for the year ended December 31, 2023 and 2022, was a expense of $7 and $2, respectively. Income taxes for the year ended December 31, 2023 and 2022, includes provisions for income tax due in respect of Ambac UK of $8 and $3, respectively. At December 31, 2023, the Company had approximately $3,400 of U.S. Federal net ordinary operating loss carryforwards, including approximately $1,640 at AFG and $1,760 at AAC.

The Legacy Financial Guarantee Insurance segment is in active runoff. This will generally result in lower premium earned, investment intangible income, operating expenses and amortization. The variability the financial results are primarily driven by changes in loss and loss adjustment expenses resulting from, amongst other litigation settlements, credit developments and de-risking transactions. Key variances not discussed above in the Consolidated Results section are as follows: items, in Net premiums earned. Net premiums earned decreased $16 for the year ended December 31, 2023, compared to the same period in the prior year. Net premiums earned were impacted by the organic and active runoff of the financial guarantee insured portfolio resulting in a reduction to current and future normal net premiums earned and the following: • Changes to the allowance for credit losses on the premium receivable asset. The positive impact on net premiums earned related to credit losses amounted to $1 and $4 for the years ended December 31, 2023 and 2022, respectively. Ambac Financial Group, Inc 41 2023 Form 10-K Specialty Property and Casualty Insurance • Accelerated financial guarantee premiums earned as a insured result of calls and other accelerations on obligations, largely due to active de-risking of the insured portfolio, were $0 and $8 for the years ended December 31, 2023 and 2022, respectively. Losses and Loss Adjustment Expenses (Benefit).

Loss and loss expenses (benefit) for 2023, was largely driven by RMBS recoveries and favorable development related to student loans, partially offset by the negative impact of discount rates on the RMBS portfolio. Changes in RMBS recoveries impacting loss and loss expenses can be volatile and therefore each period's results are not indicative of potential future results. Losses and loss expenses (benefit) for 2022, were driven by favorable RMBS development due to the impact of the settlement agreements with the BOA Parties and Nomura of $123, the positive impact of discount rates, and favorable loss development in domestic public finance (primarily due to the Puerto Rico restructurings of $180). G&A Expenses. The increase in Legacy Financial Guarantee Insurance segment operating expenses during the year ended December 31, 2023, as compared to the year ended December 31, 2022, is driven primarily by additional costs related to defensive litigation, partially offset by the impact of headcount and other cost reductions in the segment.

The Specialty Property and Casualty Insurance segment has grown significantly since underwriting its first program in May 2021. Twenty-three programs were authorized to issue policies as of December 31, 2023. The growth in both the number and size of these programs has contributed to the increase in gross and net premiums written, net premiums earned, net loss and loss adjustment expenses incurred and amortization of deferred acquisition costs. 2023 2022 $ $ $ 273 80 52 4 — 8 64 37 11 16 — — — $ $ $ $ 146 29 14 2 — 3 18 9 3 13 — (6) (6) 70.7 % 106.5 % 65.4 % 156.5 % Ambac Financial Group, Inc 42 2023 Form 10-K Losses and Loss Adjustment Expenses (Benefit). Loss and loss expenses incurred increased for the year ended December 31, 2023, relative to the year ended December 31, 2022, primarily due to the growth and diversification of the business. Everspan's loss ratio (including ULAE) was 70.7% and 65.4% for the years ended December 31, 2023 and 2022, respectively, inclusive of prior years development of 0.3% and 0.2%, respectively. The shift in the loss ratio was driven by commercial auto loss experience in the current accident year and diversification, primarily due to the addition of personal auto and workers compensation programs through assumed reinsurance. Everspan's loss ratio may shift as the inforce book of business grows and diversifies. The increase in the Loss and LAE ratio for the year ended December 31, 2023, compared to December 31, 2022, was partially offset by a benefit to acquisition costs as a result of sliding scale commission arrangements with program partners. Such benefit reduced the Specialty Property and Casualty Insurance segments expense ratio by 3.2% and 1.3% for the years ended December 31, 2023 and 2022, respectively. Certain Everspan programs were structured to include sliding scale commission arrangements within a loss ratio range. These sliding scale arrangements mitigate net income volatility. increasing economic and social Loss and loss adjustment expenses incurred may be adversely inflation, impacted by particularly within the commercial auto business. The impact of inflation on ultimate loss reserves is difficult to estimate, particularly in light of recent disruptions to the judicial system, supply chain and labor markets. In addition, going forward, we may not be able to offset the impact of inflation on our loss costs with sufficient price increases. The estimation of loss reserves may also be more difficult during extreme events, such as a pandemic, or during the persistence of volatile or uncertain economic conditions, due to, amongst other reasons, unexpected changes in behavior of judicial decisions, claimants and policyholders, including fraudulent reporting of exposures and/ or losses. Due to the inherent uncertainty underlying loss reserve estimates, the final resolution of the estimated liability for loss and loss adjustment expenses will likely be higher or lower than the related loss reserves at the reporting date. In addition, our estimate of losses and loss expenses may change. These additional liabilities or increases in estimates, or a range of either, could vary significantly from period to period. G&A Expenses. General and administrative costs increased for the year ended December 31, 2023, relative to the year ended December 31, 2022, primarily resulting from the growth in Everspan's staffing and operations. The impact of growing operations was muted by costs incurred in 2022 in connection with the acquisition of additional shell insurance companies.

(2) Represents the share of Ambac stockholders equity for each subsidiary within the Insurance Distribution segment, including intercompany eliminations. Ambac's Insurance Distribution segment, Cirrata Group "Cirrata", currently includes Xchange Benefits, a P&C MGA specializing in accident and health products; All Trans, an MGA specializing in commercial automobile insurance for specific "for-hire" auto classes; Capacity Marine, a wholesale and retail brokerage and reinsurance intermediary specializing in marine and international risk; and Riverton Insurance Agency, an insurance services business specializing in professional liability lines and consisting of a MGA and a retail agency. The Insurance Distribution business is typically compensated for its services primarily by commissions paid by insurance carriers for underwriting, structuring and/or administering polices and, in some cases, the managing of claims under an agency agreement. Commission revenues are usually based on a percentage of the premiums placed. Cirrata is also eligible to receive profit sharing contingent commissions on certain of its programs based on the underwriting results of the policies it places with the carrier, which may cause some variability in revenue and earnings. for Cirrata business placed premiums its carriers of approximately $231 for the year ended December 31, 2023, up $95 or 70% as compared to the year ended December 31, 2022. The growth was primarily driven by (i) premiums placed by All Trans and Capacity Marine since their acquisition in November 2022; (ii) premiums placed by Riverton since its acquisition in August 2023 and (iii) organic growth at Xchange of approximately 10%. Insurance Distribution businesses may experience seasonal impacts on their revenues and operations. For example, Employer Stop Loss business underwritten by Xchange has seasonality in January and July, which results in revenue and earnings concentrations in the first and third quarters each calendar year. Seasonal impacts on the Insurance Distribution segment, and therefore Ambac's results, may increase or decrease over time depending on the relative growth of certain classes of business as well as acquisitions. Ambac Financial Group, Inc 43 2023 Form 10-K G&A Expenses. General and Administrative expenses for the year ended December 31, 2023, increased as compared to the year ended December 31, 2022, as a result of the addition of the operating expenses of All Trans, Capacity Marine and Riverton, which were acquired in November 2022, November 2022, and August 2023, respectively. LIQUIDITY AND CAPITAL RESOURCES Holding Company Liquidity AFG is organized as a legal entity separate and distinct from its operating subsidiaries. AFG is a holding company with no outstanding debt. AFG’s liquidity is primarily dependent on its net assets, excluding the operating subsidiaries that it owns, totaling $211 as of December 31, 2023, and secondarily on distributions and expense sharing payments from its operating subsidiaries. • Under an inter-company cost allocation agreement, AFG is reimbursed by AAC for a portion of certain operating costs and expenses and, if approved by OCI, entitled to an additional payment of up to $4 per year to cover expenses not otherwise reimbursed. The $4 reimbursement for 2022 expenses was approved by OCI and paid to AFG in March 2023. • Substantial uncertainty remains as to AAC's ability to pay dividends to AFG and the timing of any such dividends. • Everspan's ability to make future dividend payments will mostly depend on its future profitability relative to its capital needs to support growth. Everspan is not expected to pay dividends in the near term. • Cirrata does not have any regulatory restrictions on its ability to make distributions. AFG received distributions from Cirrata of $8 and $6 during the years ended December 31, 2023 and 2022. AFG's principal uses of liquidity are: (i) the payment of operating expenses, including costs to explore opportunities to grow and diversify Ambac, (ii) the making of strategic investments, which may include illiquid investments and (iii) making capital investments to acquire, grow and/or capitalize new and/or existing businesses; such capital investments include investments in technology to support the efficient operation of our Specialty Property and Casualty Insurance and Insurance Distribution businesses. AFG may also provide short-term financial support, primarily in the form of loans, to its operating subsidiaries to support their operating requirements. AFG supported the development of the Specialty Property and Casualty Insurance business, and its acquisitions, with cash contributions of $6 and $14 to the Everspan group of companies during the years ended December 31, 2023 and 2022, respectively. In the opinion of the Company’s management, the net assets of AFG are currently sufficient to meet AFG’s current liquidity requirements. However, events, opportunities or circumstances could arise that may cause AFG to seek additional capital (e.g. through the issuance of debt, equity or hybrid securities). Operating Companies' Liquidity Insurance: Sources of liquidity for the Company’s insurance subsidiaries are through funds generated from premiums, recoveries of prior claim payments, reinsurance recoveries, fees, investment income and maturities and sales of investments. • See Note 7. Insurance Contracts to the Consolidated Financial Statements included in Part II, Item 8, in this Annual Report on Form 10-K for a summary of future gross financial guarantee premiums to be collected by AAC and Ambac UK under existing insurance policies. Termination of financial guarantee policies on an accelerated basis may adversely impact AAC’s liquidity. Cash provided from these sources is used primarily for claim payments and commutations, loss expenses, acquisition costs (Specialty Property and Casualty Insurance segment only), debt service (Legacy Financial Guarantee Insurance segment only), operating expenses, reinsurance payments and purchases of securities and other investments. • Interest and principal payments on AAC surplus notes are subject to the approval of OCI, which has full discretion over payments regardless of the liquidity position of AAC. As discussed more fully in "Results of Operations" above in this Management's Discussion and Analysis, OCI declined AAC's request to pay the principal amount of the surplus notes, plus all accrued and unpaid interest thereon, on June 7, 2023. Current principal outstanding on AAC's long-term debt consisted of $519 of surplus notes. AAC's future interest obligations on long-term debt include $475 of accrued and unpaid interest. • AFS provided to interest rate derivatives financial guarantee customers and used derivatives to provide a partial hedge against interest rate risk in AAC's insurance and investment portfolios. Since June 30, 2023, AFS' only remaining derivative positions include a limited number of legacy customer swaps and their associated hedges. AAC lends AFS cash and securities as needed to fund payments under these derivative contracts, collateral posting requirements and operating expenses. Intercompany loans are governed by an established lending agreement with defined borrowing limits that has received non-disapproval from OCI. Insurance subsidiaries manage their liquidity risk by maintaining comprehensive analyses of projected cash flows and maintaining specified levels of cash and short-term investments at all times. It is the opinion of the Company’s management that the insurance subsidiaries’ near term liquidity needs will be adequately met from the sources described above. Insurance Distribution: The liquidity requirements of our Insurance Distribution subsidiaries are met primarily by funds generated from commission receipts (both base and profit commissions). Base commissions are generally received monthly, whereas profit commissions are received only if the business underwritten is profitable. Cash provided from these sources is used primarily Ambac Financial Group, Inc 44 2023 Form 10-K for commissions paid to sub-producers, operating expenses and distributions to AFG and other members. Consolidated Cash Flow Statement Discussion The following table summarizes the net cash flows for the periods presented.

Cash used in financing activities includes $113 and $311 from such AAC payments for the years ended December 31, 2023 and 2022, respectively. Operating activities The following represents the significant cash operating activities during the years ended December 31, 2023 and 2022: • Cash provided by (i) gross premiums (net of commissions) were $209 and $139 for the years ended December 31, 2023 and 2022, respectively; (ii) non-VIE interest rate derivatives were $22 and $84 for the years ended December 31, 2023 and 2022, respectively; (iii) non-VIE investment portfolio income was $96 and $82 for the years ended December 31, 2023 and 2022, respectively; and (iv) cash settlements from the Puerto Rico restructuring transactions to the consolidated trusts were $47 for the year ended December 31, 2022. • Payments for accreted interest on redemption of the Tier 2 Notes were $50 for the year ended December 31, 2023. interest on Payments for debt service and accreted redemptions and debt repurchases of the Sitka AAC Note, Tier 2 Notes and Surplus Notes were $59, $70 and $154, respectively, for the year ended December 31, 2022. • Payments related to (i) operating expenses were $120 and $94 for the years ended December 31, 2023 and 2022, respectively; (ii) reinsurance premiums paid (net of commissions) were $137 and $66 for the years ended December 31, 2023 and 2022, respectively; and (iii) VIE the year ended derivative payments were $326 for December 31, 2022. • Fraud litigation recoveries of $126 allocated from the BOA Settlement Payment. • Net Legacy Financial Guarantee Insurance loss and loss adjustment including paid commutation payments, during the years ended December 31, 2023 and 2022 are detailed below: (recovered), expenses Year Ended December 31, Net losses paid Net subrogation received (1) Net loss expenses paid Net cash flow 2023 2022 $ 30 $ 298 (232) (1,951) 8 48 $ (194) $ (1,605) (1) 2023 includes Nomura R&W settlement proceeds of $140. 2022 includes the majority of the recoveries from the BOA Settlement Payment except for the portion allocated to fraud litigation recoveries. Future operating cash flows will primarily be impacted by net premium collections, investment coupon receipts, fee and net commission revenues, operating expenses, net claim and loss expense payments and debt interest payments. Financing Activities Financing activities for the year ended December 31, 2023, included payments for the redemption of Tier 2 Notes of $97, share repurchases of $5 and paydowns and maturities of VIE debt obligations of $315. Financing activities for the year ended December 31, 2022, included payments for repurchase of surplus notes of $191, redemption of the Sitka AAC Note of $1,210, partial redemption of Tier 2 Notes of $143, share repurchases of $14, repurchases of auction market preferred shares of $8 and paydowns and maturities of VIE debt obligations of $591 (including payments for the accelerations of the VIE trusts created from the Puerto Rico restructuring). Collateral Insurance segment and AFS hedged a portion of the interest rate risk in the Legacy Financial Guarantee investment portfolios, along with legacy customer interest rate swaps, with standardized derivative contracts which contain collateral or margin requirements. Since the second quarter of 2023, AFS's only remaining derivative positions include a limited number of legacy customer swaps and their associated hedges. Under these hedge agreements, AFS is required to post collateral in excess of the derivative unrealized loss amount. All AFS derivative contracts containing ratings-based downgrade triggers that could result in collateral posting or termination have been triggered. AFS may look to re-establish hedge positions that are terminated early, resulting in additional collateral obligations. The amount of additional collateral posted on derivatives contracts will depend on several variables including the degree to which counterparties exercise their termination rights (or agreements terminate automatically) and the terms on which hedges can be replaced. All collateral and margin obligations are currently met. Collateral posted by AFS totaled $50 (cash of $23 and securities at fair value of $27), including independent amounts, under these contracts at December 31, 2023. BALANCE SHEET Total assets increased by approximately $456 from December 31, 2022 to $8,428 at December 31, 2023, primarily due to (i) the increase in asset values of VIEs, driven by a new VIE consolidated in the fourth quarter of 2023 and the weakening of the US dollar against the British Pound Sterling and (ii) the impact on premium receivables, reinsurance recoverables and Ambac Financial Group, Inc 45 2023 Form 10-K deferred ceded premiums from growth in the Specialty Property and Casualty Insurance business. liabilities increased by approximately $349 Total from December 31, 2022, to $6,997 as of December 31, 2023, primarily due to (i) increases in the value of VIEs liabilities based on consistent factors as noted above in assets, and (ii) higher unearned premiums and ceded premiums payable from the growth in the Specialty Property and Casualty Insurance business, partially offset by the reduction in long-term debt that was fully redeemed on January 15, 2023, primarily from the Nomura Settlement Payment as more fully described in Note 1. Background and Business Description to the Consolidated Financial Statements in this Annual Report on Form 10-K located in Part II. Item 8. As of December 31, 2023, total stockholders’ equity was $1,415, compared with total stockholders’ equity of $1,305 at December 31, 2022. This increase was primarily due to a Total Comprehensive Income during 2023 primarily driven by the net income attributable to common stockholders for the year ended Investment Portfolio December 31, 2023 of $4, unrealized gains on investments of $51 and translation gains on the consolidation of AFG's foreign subsidiaries.of $40.

As further discussed in Note 7. Insurance Contracts to the Consolidated Financial Statements, in this Annual Report Form 10-K located in Part II. Item 8, the increase is primarily due to growth in the Specialty Property and Casualty Insurance Segment, including receivables related to a workers compensation program where Everspan participates as a reinsurer.

Ambac has reinsurance in place pursuant to quota share, surplus share treaty and facultative agreements. To minimize its exposure to losses from reinsurers, Ambac (i) monitors the financial condition of its reinsurers; (ii) is entitled to receive collateral from its reinsurance counterparties under certain reinsurance contracts; and (iii) has certain cancellation rights that can be exercised in the event of rating agency downgrades of a reinsurer (among other events and circumstances). For those reinsurance counterparties that do not currently post collateral, Ambac’s reinsurers are well capitalized, highly rated, authorized capacity providers. Ambac benefited from letters of credit and collateral amounting to approximately $131 from its reinsurers at December 31, 2023. As of December 31, 2023 and 2022, reinsurance recoverable on paid and unpaid losses were $195 and $115, respectively. Specialty Property and Casualty Insurance amounted to $165 and $82 at December 31, 2023 and 2022, respectively; increase driven largely from growth of the business. Legacy Financial Guarantee Insurance amounted to $30 and $33 at December 31, 2023 and 2022, respectively. Intangible Assets. Intangible assets includes (i) an insurance intangible asset that was established at AFG's emergence from bankruptcy in 2013, representing the difference between the fair value and aggregate carrying value of the financial guarantee insurance and reinsurance assets and liabilities; (ii) intangible assets established as part of the acquisition of Xchange in 2020, All Trans and Capacity Marine in 2022, and Riverton in 2023; and (iii) indefinite-lived intangible assets established as part of the acquisition of admitted carriers in both 2021 and 2022. As of December 31, 2023 and 2022, the net intangible asset was $307 and $326, respectively. The decline is driven by amortization; partially offset by translation gains from the consolidation of Ambac's foreign subsidiary (Ambac UK) and established intangibles from the acquisition of Riverton.

The table below reflects the timing of expected financial guarantee claim payments based on policy specific probability weighted cash flows, excluding expected recoveries. These deal specific cash flows are based on the expected cash flows of the underlying transactions with the majority of these payments expected at or close to the final maturity of the related insurance policy. The timing of expected claim payments for credits with reserves that were established using our statistical loss reserve method is determined based on the weighted average expected life of the exposure. Refer to the Loss Reserves section in Note 2. Basis of Presentation and Significant Accounting Policies to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K for further discussion of our statistical loss reserve method. The timing of these payments may vary significantly from the amounts shown below, especially for credits that are based on our statistical loss reserve method. ($ in millions) Claim payments Payments Due by Period Total Less Than 1 Year 1 - 3 Years 3 - 5 Years More Than 5 Years $ 1,202 $ 93 $ 51 $ 42 $ 1,016 Ambac Financial Group, Inc 48 2023 Form 10-K Variability of Expected Losses and Recoveries Ambac’s management believes loss reserves (present value of expected cash flows, net of recoveries) are adequate to cover future claim payments, but there can be no assurance that the ultimate liability will not be higher than such estimates. While our loss reserves reflect our judgment regarding issuers’ financial flexibility to adapt to adverse markets, they may not adequately capture sudden, unexpected or protracted uncertainty that adversely affects market conditions. Accordingly, it is possible that our estimated loss reserves, gross of reinsurance, for financial guarantee insurance policies could be understated. We have attempted to identify possible cash flows related to losses and recoveries using more stressful assumptions than the probability-weighted outcome recorded. The possible net cash flows consider the highest stress scenario that was utilized in the development of our probability-weighted expected loss at December 31, 2023, and assumes an inability to execute any commutation transactions with issuers and/or investors. Such stress scenarios are developed based on management’s view about all possible outcomes relating to losses and recoveries. In arriving at such view, management makes considerable judgments about the possibility of various future events. Although we do not believe it is possible to have stressed outcomes in all cases, it is possible that we could have stress case outcomes in some or even many cases. See “Risk Factors” in Part I, Item 1A in this Annual Report on Form 10-K as well as the descriptions of variability in "Structured Finance," "Public Finance," and "Other Credits, including Ambac UK," below for further discussion of the risks relating to future losses and recoveries that could result in more highly stressed outcomes appearing below. The occurrence of these stressed outcomes individually or collectively would have a material adverse effect on our results of operations and financial condition and may result in materially adverse consequence for Ambac, including (without limitation) impairing the ability of AAC to honor its financial obligations, particularly its outstanding surplus note and preferred stock obligations; the initiation of rehabilitation proceedings against AAC; decreased likelihood of AAC delivering value to AFG, through dividends or otherwise; and a significant drop in the value of securities issued or insured by AFG or AAC. Structured Finance RMBS: Changes to assumptions that could make our reserves under- estimated include an increase in interest rates, deterioration in housing prices, poor servicing, government intervention into the functioning of the mortgage market and the general effect of a weakened economy characterized by growing unemployment and wage pressures. During the first quarter of 2023, Ambac revised the model it uses to project RMBS collateral losses considering the seasoning of our RMBS exposure and management’s view that the most relevant determinant of prospective collateral performance is borrower payment status. Individual home price appreciation/depreciation has become a less critical determinant of performance considering the general appreciation in home values over the past few years as well as the impact of loan modifications. The average estimated loan- to-values of the collateral related to insured exposures have declined to under 50% from peaks above 110%. Projected losses in our RMBS exposures and related loss reserves, may increase or decrease in the future. Possible stress case losses assume higher default lower prepayments. loss severities and rates, Student Loans: Changes to assumptions that could make our reserves under- estimated include, but are not limited to, increases in interest rates, default rates and loss severities on the collateral due to economic or other factors, including the economic impact from public health crises and/or natural or other catastrophic events. Such factors may also include lower recoveries on defaulted loans or additional losses on collateral or trust assets, including as a result of any enforcement actions by the Consumer Finance Protection Bureau. During the second quarter of 2023, we revised our approach to projecting future defaults to reflect the student loan collateral's seasoning. Structured Finance Variability: Using the approaches described above, the possible increase in loss reserves for structured finance credits for which we have an estimate of expected loss at December 31, 2023, could be approximately $55. Due to the uncertainties related to risks associated with structured finance credits, there can be no assurance that losses may not exceed our stress case estimates. Public Finance Ambac’s U.S. public finance portfolio consists of municipal bonds such as general and revenue obligations and lease and tax- backed obligations of state and local government entities; however, the portfolio also includes a wide array of non- municipal types of bonds, including transactions with public and private elements, which generally finance infrastructure, housing and other public purpose facilities and interests, the largest sector of which is U.S. military housing. It is possible our loss reserves for public finance credits may be under-estimated if issuers are faced with prolonged exposure to adverse political, judicial, economic, fiscal or socioeconomic events or trends. Additionally, our loss reserves may be under- estimated because of the local, regional or national economic impact of public health crises and/or natural or other catastrophic events, or the impact of political changes or governmental decisions. Our experience with the city of Detroit's bankruptcy and Commonwealth of Puerto Rico's Title III proceedings as well as other municipal bankruptcies demonstrates the preferential treatment of certain creditor classes, especially public pensions. The cost of pensions and the need to address frequently sizable unfunded or underfunded pensions is often a key driver of stress for many municipalities and their related authorities, including entities to whom we have exposure, such as Chicago's school district, the State of New Jersey and others. Less severe treatment of pension obligations in bankruptcy may lead to worse outcomes for traditional debt creditors. Variability of outcomes applies to even what are generally considered more secure municipal financings, such as dedicated Ambac Financial Group, Inc 49 2023 Form 10-K sales tax revenue bonds that capture sales tax revenues for debt service ahead of any amounts being deposited into the general fund of an issuer. In the case of the Puerto Rico COFINA sales tax bonds that were part of the Commonwealth of Puerto Rico's Title III proceedings, AAC and other creditors agreed to settle at a recovery rate equal to about 93% of pre-petition amounts owed on the Ambac insured senior COFINA bonds. In the COFINA case, the senior bonds still received a reduction or "haircut" despite the existence of junior COFINA bonds, which received a recovery rate equal to about 56% of pre-petition amounts owed. In addition, municipal entities may be more inclined to use bankruptcy to resolve their financial stresses if they believe preferred outcomes for various creditor groups can be achieved. We expect municipal bankruptcies and defaults to continue to be challenging to project given the unique political, economic, fiscal, legal, governance and public policy differences among municipalities as well as the complexity, long duration and relative infrequency of the cases themselves in forums with a scarcity of legal precedent. Moreover, issuers in Chapter 9 or similar proceedings may obtain judicial rulings and orders that impair creditors' rights or their ability to collect on amounts owed. In certain cases, judicial decisions may be contrary to AAC's expectations or understanding of the law or its rights thereunder, which may lead to worse outcomes in Chapter 9 or similar proceedings than anticipated at the outset. Another potentially adverse development that could cause the loss reserves on our public finance credits to be underestimated is deterioration in the municipal bond market, resulting from reduced or limited access to alternative forms of credit (such as bank loans) or other exogenous factors, such as changes in tax law that could reduce certain municipal investors' appetite for tax-exempt municipal bonds or put pressure on issuers in states with high state and local taxes. These factors could deprive issuers access to funding at a level necessary to avoid defaulting on their obligations. For the public finance credits for which we have an estimate of expected loss at December 31, 2023, the sum of all the highest stress case loss scenarios is $125 and there can be no assurance that losses may not exceed such amounts. Other Credits, including Ambac UK It is possible our loss reserves on other types of credits, including those insured by Ambac UK, may be under-estimated because of various risks that vary widely, including the risk that we may not be able to recover or mitigate losses through our remediation processes. For all other credits, including Ambac UK, for which we have an estimate of expected loss, the sum of all the highest stress case loss scenarios is approximately $330 greater than the loss reserves at December 31, 2023. There can be no assurance that losses may not exceed our stress case estimates. Long-term Debt. The carrying value of each of these as of December 31, 2023 and 2022 is below: December 31, Surplus Notes Tier 2 Notes Ambac UK Debt Total Long-term Debt Accrued Interest Payable Total 2023 2022 $ 491 $ — 17 508 475 983 $ 477 146 16 639 427 $ 1,065 to The decrease in long-term debt, including accrued interest payable, from December 31, 2022 resulted primarily from the full redemption of the Tier 2 Notes in 2023, described further in Note 1. Background and Business Description the Consolidated Financial Statements, included in this Annual Report on Form 10-K, partially offset by the accrual of interest on the surplus notes and Ambac UK debt. In May 2023, OCI declined the request of AAC to pay the principal amount of the surplus notes, plus all accrued and unpaid interest thereon, on the then next scheduled payment date of June 7, 2023. As a result, the scheduled payment date for interest, and the scheduled maturity date for payment of principal of the surplus notes was extended until OCI grants approval to make the payment. Interest will accrue, compounded on each anniversary of the original scheduled payment date or scheduled maturity date, on any unpaid principal or interest through the actual date of payment, at 5.1% per annum. Holders of surplus notes will have no rights to enforce the payment of the principal of, or interest on, surplus notes in the absence of OCI approval to pay such amount. Redeemable Noncontrolling Interest. The decrease during 2023 was the result the remeasurement of the redemption value of put options provided to minority owners (noncontrolling interest holders) of Cirrata entities acquired as if the put was exercised on December 31, 2023, partially offset by new put options issued during the acquisition of Riverton during 2023. No put options are exercisable at December 31, 2023. ACCOUNTING STANDARDS Please refer to Note 2. Basis of Presentation and Significant Accounting Policies to the Consolidated Financial Statements, included in Part II, Item 8 in this Annual Report Form 10-K for a discussion of the impact of recent accounting pronouncements on Ambac’s financial condition and results of operations. U.S. STATUTORY BASIS FINANCIAL RESULTS AFG's U.S. insurance subsidiaries prepare financial statements under accounting practices prescribed or permitted by its domiciliary state regulator (“SAP”) for determining and reporting the financial condition and results of operations of an insurance company. The National Association of Insurance Commissioners (“NAIC”) Accounting Practices and Procedures manual (“NAIC SAP”) is adopted as a component of prescribed practices by each domiciliary state. For further information, see Note 8. Insurance Regulatory Restrictions to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report Form 10-K. Ambac Assurance Corporation AAC’s statutory policyholder surplus and qualified statutory capital (defined as the sum of policyholders surplus and Ambac Financial Group, Inc 50 2023 Form 10-K mandatory contingency reserves) were $897 and $1,201, respectively, at December 31, 2023, as compared to $598 and $1,191, respectively, at December 31, 2022. As of December 31, 2023, statutory policyholder surplus and qualified statutory capital included $519 principal balance of surplus notes outstanding and $115 liquidation preference of preferred stock outstanding. These surplus notes (including related accrued interest of $475 that is not recorded under statutory basis accounting principles); preferred stock; and all other liabilities, including insurance claims are obligations that, individually and collectively, have claims on the resources of AAC that are senior to AFG's equity and therefore impede AFG's ability to realize residual value and/or receive dividends from AAC. The significant drivers to the net increase in policyholder surplus of $301 during 2023 was a reduction to contingency reserves of $290 and investment valuation changes that are direct charges to surplus of $10. The decline in contingency reserves was the result of the release of excess contingency reserves (which was approved by OCI) of $298. insured obligations, which AAC's statutory surplus, and therefore AFG's ultimate ability to realize residual value and/or dividends from AAC, is sensitive to multiple factors, including: (i) loss reserve development, (ii) timing of surplus note payments, (iii) ongoing interest costs associated with surplus notes, (iv) swap gains and losses at AFS, the financial position of which is supported by certain guarantees and financing arrangements from AAC, (v) first time payment defaults of increase statutory loss reserves, (vi) commutations of insurance policies at amounts that differ from the amount of liabilities recorded, (vii) reinsurance contract terminations at amounts that differ from net assets recorded, (viii) changes to the fair value of pooled fund and other investments carried at fair value, (ix) realized gains and losses, including losses arising from other than temporary impairments of investment securities, (x) the ultimate residual value of Ambac UK, which is currently a non- admitted asset under SAP and may be impacted by numerous factors including foreign exchange rates, and (xi) future changes to prescribed practices by the OCI. The significant differences between GAAP and SAP are that under SAP: • Under SAP, loss reserves are only established for losses on guaranteed obligations that have experienced a payment default. Loss reserves are established in an amount that is sufficient to cover the present value of the anticipated defaulted debt service payments over the expected period of default, less estimated recoveries under subrogation rights (5.1% as prescribed by OCI). Under GAAP, in addition to the establishment of loss reserves for defaulted obligations, loss reserves are established (net of GAAP basis unearned premium revenue) for obligations that have experienced credit deterioration, but have not yet defaulted using a weighted-average risk-free discount rate, currently at 3.9%. • Mandatory contingency reserves are required based upon the type of obligation insured, whereas GAAP does not require such a reserve. Releases of the contingency reserves are generally subject to OCI approval and relate to a determination that the held reserves are deemed excessive. • Investment grade fixed maturity investments are stated at amortized cost and certain below investment grade fixed maturity investments are reported at the lower of amortized cost or fair value. Under GAAP, all fixed maturity investments are reported at fair value. • Majority owned subsidiaries are not consolidated; rather, the equity basis of accounting is utilized and the carrying values of these investments are subject to admissibility tests. Ambac Assurance's cash loan to AFS is included on the SAP balance sheet, net of an allowance for uncollectible amounts and changes in the allowance are recognized through other income. Under GAAP, all inter- company transactions are eliminated in consolidation. • Variable interest entities ("VIE") are not required to be assessed for consolidation. Under GAAP, a reporting entity that has both the following characteristics is required to consolidate the VIE: a) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance and b) the obligation to absorb losses of the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE. AAC generally has the obligation to absorb losses of VIEs that could potentially be significant to the VIE as the result of its guarantee of insured obligations issued by VIEs. For certain VIEs AAC has the power to direct the most significant activities of the VIE and accordingly consolidates the related VIEs under GAAP. • Under SAP, unpaid interest due on the surplus notes is expensed when the approval for payment of interest has been granted by the OCI. Under GAAP, interest on surplus notes is accrued regardless of OCI approval. Under SAP, the principal balance of surplus notes is included in surplus whereas under GAAP surplus note principal is reported at par, less unamortized discount within long-term debt. All payments of principal and interest on surplus notes are subject to the approval of the OCI. • Upfront premiums written are earned on a basis proportionate to the remaining scheduled debt service to the original total principal and interest insured. Installment premiums are reflected in income pro-rata over the period covered by the premium payment. Under GAAP, premium revenues for both upfront and installment premiums are earned over the life of the financial guarantee contract in proportion to the insured principal amount outstanding at each reporting date. Under GAAP, for installment premium transactions, a premium receivable asset and offsetting UPR liability are established in an amount equal to the present value of future premiums to be collected over the life of the transaction. • Insurance intangibles that arose as a result of the implementation of Fresh Start reporting are not a concept within SAP. This insurance intangible asset is amortized as an expense on a level yield basis over the life of the related insurance risks. • Unearned premiums and loss reserves are presented net of ceded amounts, while under GAAP, they are reflected gross of ceded amounts. Ambac Financial Group, Inc 51 2023 Form 10-K Everspan Indemnity Insurance Company Indemnity statutory Everspan policyholder surplus was $108 at December 31, 2023, as compared to $107 at December 31, 2022. Insurance Company’s The significant changes to policyholder surplus for the year ended December 31, 2023, were total capital contributions of $7.3, offset by a net loss at Everspan Indemnity Insurance Company, including its subsidiaries, of $7.1 during the year ended December 31, 2023, primarily driven by G&A expenses as the business continues to scale. Acquisition costs, primarily commissions, are generally expensed immediately whereas the related premium is recognized over the life of the policy. The significant differences between GAAP and SAP are that under SAP: • Investment grade fixed maturity investments are stated at amortized cost and certain below investment grade fixed maturity investments are reported at the lower of amortized cost or fair value. Under GAAP, all fixed maturity investments are reported at fair value. • Majority owned subsidiaries are not consolidated; rather, the equity basis of accounting is utilized and the carrying values of these investments are subject to admissibility Providence Washington Insurance Company's tests. ("PWIC") and the 21st Century Companies' (as defined in Note 7. Insurance Contracts in Part II, Item 8 in the Consolidated Financial Statements included in this Annual Report on Form 10-K) carrying values include a goodwill component representing the acquisition cost in excess of the related entity's statutory surplus. Goodwill is amortized over ten years. Under GAAP, the initial acquisition of the companies were recorded as asset acquisitions, which required i) all net assets to initially be recorded at fair value, and ii) the acquisition costs in excess of the fair value of net assets to be allocated to the bases of certain types of assets based on their relative fair values, if applicable. Acquired assets include intangible assets with indefinite lives. Such assets are not amortized but their estimated useful lives are reevaluated each reporting period. No goodwill is recorded for asset acquisitions. • Acquisition costs and ceding commissions, other than excess ceding commissions, are expensed or recognized at the time of a transaction. Under GAAP, acquisition costs and ceding commissions are deferred and recognized over the life of the related transaction. • Unearned premiums and loss reserves are presented net of ceded amounts, while under GAAP, they are reflected gross of ceded amounts. AMBAC UK FINANCIAL RESULTS UNDER UK ACCOUNTING PRINCIPLES Ambac UK is required to prepare financial statements under FRS 102 "The Financial Reporting Standard applicable in the UK and Republic of Ireland." Ambac UK’s shareholder funds under UK GAAP were £489 at December 31, 2023, as compared to £468 at December 31, 2022. At December 31, 2023, the carrying value of cash and investments was £535, an increase from £508 at December 31, 2022. The increase in shareholder funds and cash and investments was primarily due to the continued receipt of premiums and investment income, and from investment foreign exchange gains within Ambac UK's portfolio, partially offset by loss expenses, operating expenses and tax payments. The significant differences between US GAAP and UK GAAP are that under UK GAAP: • Loss reserves are only established for losses on guaranteed obligations when, in the judgment of management, a monetary default in the timely payment of debt service is likely to occur, which would result in Ambac UK incurring a loss. A loss provision is established in an amount that is sufficient to cover the present value of the anticipated defaulted debt service payments over the expected period of default, less estimated recoveries under subrogation rights. The discount rate for loss provisions is equal to the lower of the rate of return on invested assets for either the current year or the period covering the current year plus the four previous years, currently at 3.2%. The discount rate used for estimated recoveries under subrogation rights is reflective of the credit risk of the counterparty from which subrogation will be received, currently 5.3%. Under U.S. GAAP, loss reserves are established (net of US GAAP basis unearned premium revenue) for obligations that have experienced credit deterioration, but have not yet defaulted using a weighted-average risk-free discount rate, currently at 3.9%. • Investments in fixed maturity securities are stated at amortized cost, subject to an other-than-temporary impairment evaluation. Under US GAAP, all fixed maturity investments are reported at fair value. • VIEs are not required to be assessed for consolidation. Under US GAAP, as noted under U.S. Statutory Basis Financial Results above, VIE's with certain characteristics are required to be consolidated. For several VIEs Ambac UK has the power to direct the most significant activities of the VIE and accordingly consolidates the related VIEs under U.S. GAAP. • Upfront premiums written are earned on a basis proportionate to the remaining scheduled debt service to the total principal and interest insured. Installment premiums are reflected in income pro-rata over the period covered by the premium payment. Under US GAAP, premium revenues for both upfront and installment premiums are earned over the life of the financial guarantee contract in proportion to the insured principal amount outstanding at each reporting date. Under GAAP, for installment premium transactions, a premium receivable asset and offsetting UPR liability are established in an amount equal to the present value of future premiums to be collected over the life of the transaction. • Insurance intangibles that arose as a result of the implementation of Fresh Start reporting are not a concept within UK GAAP. Under US GAAP, this insurance intangible asset is amortized as an expense on a level yield basis over the life of the related insurance risks. • Unearned premiums and loss reserves are presented net of ceded amounts, while under GAAP, they are reflected gross of ceded amounts. Ambac Financial Group, Inc 52 2023 Form 10-K Ambac UK is also required to prepare financial information in accordance with the Solvency II Directive. The basis of preparation of this information is significantly different from both US GAAP and UK GAAP. Available and eligible capital resources under Solvency II, to meet solvency capital requirements, were £430 at December 31, 2023. This is an increase from December 31, 2022, when available and eligible capital resources to meet solvency capital requirements were £338. Eligible capital resources at December 31, 2023 and December 31, 2022, are in comparison to regulatory capital requirements of £220 and £213, respectively. Therefore, Ambac UK was in a surplus position in terms of compliance with applicable regulatory capital requirements by £210 at December 31, 2023, and was in a surplus position by £125 at December 31, 2022. The surplus increased as of December 31, 2023, due to the combined impact of (i) a decrease in technical provision liabilities and hence an increase in eligible own funds due to regulatory changes which came into effect in December 2023 and (ii) an increase in eligible own funds from the increase in investments over the year. Final annual Solvency II data and Ambac UK's annual Solvency and Financial Condition Report will be published on Ambac's website in April 2023. NON-GAAP FINANCIAL MEASURES In addition to reporting the Company’s quarterly financial results in accordance with GAAP, the Company is reporting non-GAAP financial measures: EBITDA, Adjusted Net Income and Adjusted Book Value. These amounts are derived from our consolidated financial information, but are not presented in our consolidated financial statements prepared in accordance with GAAP. into We present non-GAAP supplemental financial information because we believe such information is of interest to the investment community, and that it provides greater transparency and enhanced visibility the underlying drivers and performance of our businesses on a basis that may not be otherwise apparent on a GAAP basis. We view these non-GAAP financial measures as important indicators when assessing and evaluating our performance on a segmented and consolidated basis and they are presented to improve the comparability of our results between periods by eliminating the impact of the items that may not be representative of our core operating performance. These non-GAAP financial measures are not substitutes for the Company’s GAAP reporting, should not be viewed in isolation and may differ from similar reporting provided by other companies, which may define non-GAAP measures differently. Beginning January 1, 2023, Ambac replaced the non-GAAP measure Adjusted Earnings with a new non-GAAP measure Adjusted Net Income to better align with other participants in the Property & Casualty insurance industry, including insurance carriers and other peers in the insurance distribution business. We are presenting Adjusted Net Income for the current and prior periods contained within this Form 10-K so this non-GAAP financial measure compares both periods on the same basis. The following paragraphs define each non-GAAP financial measure. A tabular reconciliation of the non-GAAP financial measure and the most comparable GAAP financial measure is also presented below. EBITDA — We define EBITDA as net income (loss) before interest expense, income taxes, depreciation and amortization of intangible assets.

The noncontrolling interest are primarily in the Insurance Distribution segment. Adjusted Net Income (Loss) — We define Adjusted Net Income (Loss) as net income (loss) attributable to common stockholders adjusted to reflect the following items: (i) net investment (gains) losses, including impairments; (ii) amortization of intangible assets; (iii) litigation costs, including attorneys fees and other expenses to defend litigation against the Company, excluding loss adjustment expenses; (iv) foreign exchange (gains) losses; (v) workforce change costs, which primarily include severance and other costs related to employee terminations; and (vi) net (gain) loss on extinguishment of debt.

Adjusted Book Value. Adjusted book value is defined as Total Ambac Financial Group, Inc. stockholders’ equity as reported under GAAP, adjusted for after-tax impact of the following: • emergence Insurance intangible asset: Elimination of the financial guarantee insurance intangible asset that arose as a result of Ambac’s the from implementation of Fresh Start reporting. This adjustment ensures that all financial guarantee contracts are accounted for within adjusted book value consistent with the provisions of the Financial Services—Insurance Topic of the ASC. bankruptcy and • Net unearned premiums and fees in excess of expected losses: Addition of the value of the unearned premium revenue ("UPR") on financial guarantee contracts, in excess of expected losses, net of reinsurance. This non-GAAP adjustment presents the economics of UPR and expected losses for financial guarantee contracts on a consistent basis. In accordance with GAAP, stockholders’ equity reflects a reduction for expected losses only to the extent they exceed UPR. However, when expected losses are less than UPR for a financial guarantee contract, neither expected losses nor UPR have an impact on stockholders’ equity. This non-GAAP adjustment adds UPR in excess of expected losses, net of reinsurance, to stockholders’ equity for financial guarantee contracts where expected losses are less than UPR. This adjustment is only made for financial guarantee contracts since such premiums are non- refundable. • Net unrealized investment (gains) losses in Accumulated the Other Comprehensive unrealized gains and losses on the Company’s investments that are recorded as a component of accumulated other comprehensive income (“AOCI”), net of income taxes. Income: Elimination of Ambac has a significant U.S. tax net operating loss (“NOL”) that is offset by a full valuation allowance in the GAAP consolidated financial statements. As a result of this, tax planning strategies and other considerations, we utilized a 0% effective tax rate for non-GAAP operating adjustments to Adjusted Book. The following table reconciles Total Ambac Financial Group, Inc. stockholders’ equity to the non-GAAP measure Adjusted Book Value on a dollar amount and per share basis, for all periods presented: ($ in millions, except per share data) December 31, Total Ambac Financial Group, Inc. stockholders’ equity Adjustments: Insurance intangible asset Net unearned premiums and fees in excess of expected losses Net unrealized investment (gains) losses in Accumulated Other Comprehensive Income (Loss) 2023 2022 $ Amount Per Share $ Amount Per Share $ 1,362 $ 30.13 $ 1,252 $ 27.85 (245) 162 20 (5.43) 3.59 0.45 (266) 214 71 (5.91) 4.76 1.59 28.29 Adjusted Book Value $ 1,299 $ 28.74 $ 1,272 $ The increase in Adjusted Book was primarily attributable to Ambac's net income for the year ended December 31, 2023 (excluding earned premium previously included in Adjusted Book Value) and the positive effect of foreign exchange rates on the consolidation of AFG's foreign subsidiaries, partially offset by the impact of the reinsurance de-risking transaction executed during 2023. Factors that impact changes to Adjusted Book Value include many of the same factors that impact Adjusted Net Income, including the majority of revenues and expenses, but generally exclude components of premium earnings since they are embedded in prior period's Adjusted Book Value through the net unearned premiums and fees in excess of expected losses adjustment. Net unearned premiums and fees in excess of expected losses will affect Adjusted Book Value for (i) changes to future premium assumptions (e.g. expected term, interest rates, foreign currency rates, time passage) and (ii) changes to expected losses for policies which do not exceed their related unearned premiums and (iii) new reinsurance transactions. Item 7A. Quantitative and Qualitative Disclosures about Market Risk ($ in millions) Market risk represents the potential for loss due to adverse changes in the fair value of financial instruments, as a result of changes in market rates and prices, such as interest rates (inclusive of credit spreads), foreign currency exchange rates and other relevant market rate or price changes. Market risk is, in part, a function of the markets in which the underlying assets are traded. The Company’s market risk sensitive financial instruments are primarily entered into for purposes other than trading. As discussed further below, the Company’s primary market risk exposures include those from changes in interest rates, foreign currency exchange rates and equity values of limited partnership and other alternative investments. • The primary market risks for fixed maturity investment securities are interest rate risk and foreign exchange rate risk. Ambac’s fixed maturity investment portfolio includes securities denominated both in U.S. dollars and foreign currencies, which are sensitive to changes in interest rates and foreign currency exchange rates. Our fixed maturity investments are generally classified as available for sale, recognized with the effect of market movements Ambac Financial Group, Inc 55 2023 Form 10-K immediately through Other comprehensive income, or through Net income when securities are sold or when an impairment charge is recorded, although certain securities held at December 31, 2023, are classified as trading with changes in fair value reported through Net income as they occur. • Ambac also invests in limited partnerships and other alternative investments, primarily consisting of diversified pooled investment funds, which are reported as Other investments. These funds are subject to equity value changes driven primarily by changes to their respective net asset value (“NAV”). Ambac’s share of the changes of the equity value of the funds is reported through Net income. For additional information about Ambac’s investments, see Note 4. Investments in this Annual Report on Form 10-K located in Part II. Item 8. • As of December 31, 2022, the interest rate derivatives portfolio was managed as a partial hedge against the effects of rising interest rates elsewhere in the Company, including on Ambac's financial guarantee exposures. As of December 31, 2023, the interest rate derivatives portfolio contains only legacy interest rate swaps with financial guarantee counterparties and associated hedges. Changes in fair value of interest rate derivatives are recognized immediately through Net income. For additional information about Ambac’s interest rate derivatives, see Note 9. Derivative Instruments to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K. • Although our long-term debt obligations are reported at amortized cost and not adjusted for fair value changes, changes in interest rates could have a material impact on their fair value, though with no direct impact on our additional consolidated information about Ambac’s debt obligations, see Note 12. Long-term Debt to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K. statements. financial For risk Fixed maturity investment securities that are distressed Ambac- insured bonds have market risk characteristics that behave inversely to those associated with future financial guarantee claim payments. Accordingly, such securities are excluded from sensitivity measures below. Financial the market instruments of VIEs that are consolidated as a result of Ambac financial guarantees are also excluded from Ambac's measures of market risk. Ambac’s exposure to such consolidated VIEs is generally limited to financial guarantees outstanding on the VIEs’ liabilities or assets. See Note 11. Variable Interest Entities to the Consolidated Financial Statements included in Part II, Item 8 in this Annual Report on Form 10-K for further information about VIEs consolidated as a result of Ambac’s financial guarantees. Ambac utilizes various systems, models and sensitivity scenarios to monitor and manage market risk. These models include estimates, made by management, which utilize current and historical market information. This market information is considered in management’s judgments about adverse sensitivity scenarios that are reasonably possible to occur in the near-term. The impact of these scenarios do not consider the possible simultaneous movement in other market rates or prices, actions of management or other factors that could lessen or worsen actual results. For these reasons, the valuation results from these models could differ materially from amounts actually realized in the market. Market Risk Sensitivities Interest Rate Risk. Financial instruments for which fair value may be affected by changes in interest rates consist primarily of fixed maturity investment securities, long-term debt and interest rate derivatives. Increases to interest rates would result in declines in the fair value of our fixed maturity investment portfolio. Interest rate increases would also have a negative economic impact on expected future claim payments within the financial guarantee portfolio, primarily related to RMBS and student loan policies. Conversely, interest rate increases would generally lower the fair value of our debt obligations and (at December 31, 2022) result in net fair value gains on interest rate derivatives. Interest rate changes do not have a significant interest rate derivatives position at December 31, 2023. Ambac performs scenario testing to measure the potential for losses in volatile markets. These scenario tests include parallel and non-parallel shifts in the benchmark interest rate curve. We also monitor our interest rates exposure through periodic reviews of projected cash flows and durations of our asset and liability positions. impact on Ambac's net The following table summarizes the estimated change in fair value of our fixed maturity investment portfolio from a hypothetical immediate increase in interest rates of 100 basis points across the yield curve as of December 31, 2023 and 2022: December 31, Fair value of fixed maturity investment (1) Pre-tax impact of 100 basis point increase in interest rates 2023 2022 $ 1,820 $ 1,740 Decrease in dollars As a percent of fair value $ (50) $ (53) 3 % 3 % (1) Excludes investments in distressed Ambac-insured securities and securities held by VIEs consolidated as a result of Ambac’s financial guarantees The following table presents the impact on the fair value of our long-term debt obligations and interest rate derivatives of a hypothetical immediate decrease in interest rates of 100 basis points across the yield curve as of December 31, 2023 and 2022: December 31, Fair value of long-term debt including accrued interest (1) Pre-tax impact of 100 basis point decrease in interest rates Increase in dollars As a percent of fair value Fair value of interest rate derivative net assets (liabilities) (1) Pre-tax impact of 100 basis point decrease in interest rates 2023 2022 $ (697) $ (878) $ (24) $ (18) 3 % 2 % $ (10) $ (12) Pre-tax loss from change in fair value in dollars $ (4) $ (20) (1) Excludes long-term debt and derivative instruments of VIEs consolidated as a result of Ambac’s financial guarantees Ambac Financial Group, Inc 56 2023 Form 10-K Foreign Currency Risk. Ambac has fixed maturity investments and investments in pooled funds denominated in currencies other than the U.S. dollar, primarily British pounds sterling and Euro. These financial instruments are primarily invested assets of Ambac UK and are held in consideration of non-U.S. dollar exposure in the financial guarantee insurance portfolio and operations of Ambac UK. The adverse fair value impact of a stronger U.S. dollar relative to other currencies on investment holdings would be directionally offset by the economic benefits to non-U.S. dollar financial guarantees and other risk exposures. The following table summarizes the estimated decrease in fair value of these financial instruments assuming immediate 20% strengthening of the U.S. dollar relative to the foreign currencies as of December 31, 2023 and 2022: December 31, Fair value of investments denominated in currencies other than the U.S. dollar (1) Pre-tax impact of 20% strengthening of the U.S. dollar 2023 2022 $ $ 463 $ 398 (93) $ (80) (1) Excludes investments in distressed Ambac-insured securities and securities held by VIEs consolidated as a result of Ambac’s financial guarantees Equity Sensitivity. Ambac’s investment portfolio includes equity and partnership interests in pooled funds with diverse asset holdings and strategies. The table below summarizes the decrease in fair value of Ambac’s pooled fund investments that would occur assuming an immediate and uniform 10% decline in NAV of the funds. The selection of a 10% fair value stress is made only as an illustration of the hypothetical impact of adverse market movements on Ambac’s investments with equity value sensitivity. Actual market shocks could have materially different aggregate results and would likely not have a uniform impact on all funds given the diversity of the funds’ holdings and strategies.

A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. /s/ KPMG LLP New York, New York February 27, 2024 To the Stockholders and Board of Directors Ambac Financial Group, Inc.: Opinion on Internal Control Over Financial Reporting We have audited Ambac Financial Group, Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2023 and 2022, the related consolidated statements of total comprehensive income (loss), stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes and financial statement schedules I, II and III (collectively, the consolidated financial statements), and our report dated February 27, 2024 expressed an unqualified opinion on those consolidated financial statements. Basis for Opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Ambac Financial Group, Inc 59 2023 Form 10-K Report of Independent Registered Public Accounting Firm To the Stockholders and Board of Directors Ambac Financial Group, Inc.: Opinion on the Consolidated Financial Statements Critical Audit Matter We have audited the accompanying consolidated balance sheets of Ambac Financial Group, Inc. and subsidiaries (the Company) as of December 31, 2023 and 2022, the related consolidated statements of total comprehensive income (loss), stockholders’ equity, and cash flows for each of the years in the three-year period ended December 31, 2023, and the related notes and financial statement schedules I, II and III (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2023, in conformity with U.S. generally accepted accounting principles. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 27, 2024 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. Basis for Opinion These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion. The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. Estimate of loss and loss adjustment expense reserves and subrogation recoverable As described in Notes 2 and 7 to the consolidated financial statements, the Company estimates financial guarantee loss and loss adjustment expense reserves and subrogation recoverable (loss reserves) on a policy-by-policy basis based upon the present value of expected net claim cash outflows or expected net recovery cash inflows, discounted at risk-free rates. Expected net claim cash outflows represent the present value of expected claim cash outflows, less the present value of expected recovery cash inflows. For such policies, a loss and loss adjustment expense reserves liability is recorded for the present value of expected net claim cash outflows in excess of the related unearned premium revenue. Expected net recovery cash inflows represent the present value of expected recovery cash inflows, less the present value of expected claim cash outflows. For such policies, a subrogation recoverable asset is recorded. As of December 31, 2023, the Company recorded loss and loss adjustment expense reserves of $893 million and subrogation recoverable of $137 million. We identified the evaluation of loss adjustment reserves as a critical audit matter. The evaluation encompassed the assessment of the loss reserves methodologies, including those methods used to estimate the following assumptions: (1) credit worthiness of the issuer of the insured security, (2) the likelihood of possible outcomes regarding the probability of default by the issuer of the insured security, (3) the expected loss severity for each insurance policy, and (4) the probability of remediation, settlement and restructuring outcomes. The evaluation of the methods and the impact of these assumptions required specialized skills and subjective and complex auditor judgment due to a high level of estimation uncertainty. The following are the primary procedures we performed to address this critical audit matter. With the assistance of credit risk and valuation professionals with specialized industry knowledge and experience, we evaluated the design and tested the operating effectiveness of certain internal controls related to the Company's estimation of loss reserves. This included controls related to the determination of the assumptions and the sources of data and the analysis of the loss reserves. We involved credit risk professionals with specialized skills and Ambac Financial Group, Inc 60 2023 Form 10-K knowledge, who assisted in assessing the individual issuer ratings and credit classifications for certain policies by evaluating the financial performance of the issuer of the insured security and underlying collateral. We also involved valuation professionals with specialized skills and knowledge, who assisted in: • evaluating the methods used to estimate loss reserves for compliance with U.S. generally accepted accounting principles, • evaluating, for certain policies, the assumptions, including: the likelihood of possible outcomes regarding the probability of default by the issuer of the insured security; the expected loss severity for each insurance policy; and, the probability of remediation, settlement and restructuring outcomes, and the sources of data and assumptions used in the calculation of loss reserves by comparing to the Company’s internal experience and related historical and industry trends. /s/ KPMG LLP We have served as the Company’s auditor since 1985.

AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) 1. BACKGROUND AND BUSINESS DESCRIPTION Ambac Financial Group, Inc. (“AFG”), headquartered in New York City, is a financial services holding company incorporated in the state of Delaware on April 29, 1991. References to “Ambac,” the “Company,” “we,” “our,” and “us” are to AFG and its subsidiaries, as the context requires. Ambac's business operations include: • Legacy Financial Guarantee Insurance — Ambac's financial guarantee business includes the activities of Ambac Assurance Corporation ("AAC") and its wholly owned subsidiaries, including Ambac Assurance UK Limited (“Ambac UK”) and Ambac Financial Services LLC ("AFS"). Both AAC and Ambac UK have financial guarantee insurance portfolios that have been in runoff since 2008. AFS provided interest rate derivatives to financial guarantee customers and used derivatives to hedge interest rate risk in AAC's insurance and investment portfolios. Since June 2023, AFS' only remaining derivative positions include a limited number of legacy customer swaps and their associated hedges. • Specialty Property and Casualty Insurance — Ambac's Specialty Property and Casualty Insurance program business includes five admitted carriers and an excess and insurer surplus (collectively, “Everspan”). Everspan carriers have an AM Best rating of 'A-' (Excellent). “nonadmitted”) (“E&S” or lines • Insurance Distribution — Ambac's specialty property and casualty ("P&C") insurance distribution business, which currently includes Managing General Agents and Underwriters (collectively "MGAs") and insurance brokers. Currently includes (i) Xchange Benefits, LLC (“Xchange”), a P&C MGA specializing in accident and health products, (ii) All Trans Risk Solutions, LLC ("All Trans"), an MGA specializing in specialty commercial automobile insurance for specific "for-hire" auto classes, (iii) Capacity Marine Corporation ("Capacity Marine"), a wholesale and retail brokerage and reinsurance intermediary specializing in marine and international risk, and (iv) Riverton Insurance Agency, Corp. ("Riverton"), which was acquired on August 1, 2023, an insurance services business specializing in professional liability lines and consisting of an MGA and a retail agency. Both All Trans and Capacity Marine Corporation were acquired in November 2022. Beginning in 2022, the Company began reporting these three business operations as segments; see Note 3. Segment Information for further information. Limitations on Voting and Transfer of Common Stock AFG’s Amended and Restated Certificate of Incorporation limits voting and transfer rights of stockholders in significant ways. Article IV contains voting restrictions applicable to any person owning at least 10% of AFG's common stock so that such person (including any group consisting of such person and any other person with whom such person or any affiliate or associate of such person has any agreement, contract, arrangement or understanding with respect to acquiring, voting, holding or disposing of AFG’s common stock) shall not be entitled to cast votes in excess of one vote less than 10% of the votes entitled to be cast by all common stock holders, except as otherwise approved by the OCI (as defined below). Article XII contains substantial restrictions on the ability to transfer AFG’s common stock. In order to preserve certain tax benefits, subject to limited exceptions, any attempted transfer of common stock shall be prohibited and void to the extent that, as a result of such transfer (or any series of transfers of which such transfer is a part), either (i) any person or group of persons shall become a holder of 5% or more of AFG’s common stock or (ii) the percentage stock ownership interest in AFG of any holder of 5% or more of AFG’s common stock shall be increased (a “Prohibited Transfer”). These restrictions shall not apply to an attempted transfer if the transferor or the transferee obtains the written approval of AFG’s Board of Directors to such transfer. A purported transferee of a Prohibited Transfer shall not be recognized as a stockholder of AFG for any purpose whatsoever in respect of the securities which are the subject of the Prohibited Transfer (the “Excess Securities”). Until the Excess Securities are acquired by another person in a transfer that is not a Prohibited Transfer, the purported transferee of a Prohibited Transfer shall not be entitled with respect to such Excess Securities to any rights of stockholders of AFG, including, without limitation, the right to vote such Excess Securities and to receive dividends or distributions, whether liquidating or otherwise, in respect thereof, if any. Once the Excess Securities have been acquired in a transfer that is not a Prohibited Transfer, the securities shall cease to be Excess Securities. If the Board determines that a transfer of securities constitutes a Prohibited Transfer then, upon written demand by AFG, the purported transferee shall transfer or cause to be transferred any certificate or other evidence of ownership of the Excess Securities within the purported transferee’s possession or control, together with any distributions paid by AFG with respect to such Excess Securities, to an agent designated by AFG. Such agent shall thereafter sell such Excess Securities and the proceeds of such sale shall be distributed as set forth in the Amended and Restated Certificate of Incorporation. If the purported transferee of a Prohibited Transfer has resold the Excess Securities before receiving such demand, such person shall be deemed to have sold the Excess Securities for AFG’s agent and shall be required to transfer to such agent the proceeds of such sale, which shall be distributed as set forth in the Amended and Restated Certificate of Incorporation. Strategies to Enhance Shareholder Value is The Company's primary goal long-term shareholder value through the execution of targeted strategies for its (i) Specialty Property and Casualty Insurance and Insurance Distribution businesses and (ii) Legacy Financial Guarantee Insurance business. to maximize Specialty Property and Casualty Insurance and Insurance Distribution strategic priorities include: • Growing our Specialty Property and Casualty Insurance business to generate underwriting profits from a diversified Ambac Financial Group, Inc 66 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) portfolio of commercial and personal accessed primarily through program administrators. liability risks • Expanding our Insurance Distribution business based on deep domain knowledge in specialty and niche classes of risk which generate attractive margins at scale. This will be achieved through acquisitions, establishing new businesses “de-novo,” and organic growth and diversification supported by a centralized technology led shared services offering. • Making opportunistic investments that are strategic to both the Specialty Property and Casualty Insurance and Insurance Distribution businesses. Legacy Financial Guarantee Insurance strategic priorities include: • Actively managing, de-risking and mitigating insured portfolio risk, and pursuing recoveries of previously paid losses. • Improving operating efficiency and optimizing our asset and liability profile. • Exploring strategic options to further maximize value for AFG. The execution of Ambac’s strategy to increase the value of its investment in AAC is subject to the restrictions set forth in the Settlement Agreement, dated as of June 7, 2010, as amended (the "Settlement Agreement"), by and among AAC, Ambac Credit Products LLC ("ACP"), AFG and certain counterparties to credit default swaps with ACP that were guaranteed by AAC, as well as the Stipulation and Order among the OCI, AFG and AAC that became effective on February 22, 2024 (the “Stipulation and Order”), replacing the Stipulation and Order that became effective on February 12, 2018, as amended (the "2018 Stipulation and Order"), each of which requires OCI and, under certain circumstances contemplated by the Settlement Agreement, holders of surplus notes, to approve certain actions taken by or in respect of AAC. In exercising its approval rights, OCI will act for the benefit of policyholders, and will not take into account the interests of AFG. The Settlement Agreement limits certain activities of AAC and its subsidiaries, such as issuing indebtedness; engaging in mergers and similar transactions; disposing of assets; making restricted payments; creating or permitting liens; engaging in transactions with affiliates; modifying or creating tax sharing agreements; and taking certain actions with respect to surplus notes (among other restrictions and limitations). The Settlement Agreement includes certain allowances with respect to these activities and generally requires the approval of OCI and, in some cases, holders of surplus notes issued pursuant to the Settlement Agreement, for consents, waivers or amendments. The Stipulation and Order requires AAC to maintain a level of surplus and contingency reserves as regards policyholders which provide reasonable security against contingencies affecting AAC’s financial position that are not otherwise fully covered by reserves or reinsurance; discount loss reserves in a manner approved by OCI; maintain OCI’s Runoff Capital Framework according to parameters specified by OCI; pay the costs of consultants and other experts retained by OCI; limit affiliate transactions and the payment of any dividend or other distribution without the prior non-disapproval of OCI; notify OCI of events that would or would be reasonably likely to cause a material adverse effect to AAC or its affiliates; obtain OCI’s non-disapproval to exercise certain control rights with respect to certain policies that were previously allocated to the Segregated Account of AAC; obtain OCI’s approval for non-ordinary course transactions involving consideration to be paid by AAC of $100 or more; and obtain OCI’s approval of any changes to AAC’s The investment policy or derivative use plan. Stipulation and Order also requires AFG to use its best efforts to preserve the use of NOLs for the benefit of AAC and its subsidiaries. The Stipulation and Order differs from the 2018 Stipulation and Order in that the 2018 Stipulation and Order (i) did not refer to OCI’s Runoff Capital Framework; (ii) included certain affirmative covenants concerning books and records, and reporting of information or events, that were not included in the Stipulation and Order; and (iii) contained a more restrictive limitation on transactions with affiliates. The Stipulation and Order has no fixed term and may be terminated or modified only with the approval of OCI. OCI reserved the right to modify or terminate the Stipulation and Order in a manner consistent with the interests of policyholders, creditors and the public generally. The execution of Ambac’s strategy to increase the value of its investment in AAC may be affected by a new capital framework developed and implemented by OCI to assist OCI with making decisions related to capital management at AAC ("OCI's Runoff Capital Framework"). OCI’s Runoff Capital Framework applies risk-based and other adjustments to AAC’s assets and insured liabilities, as determined by OCI in its sole discretion. OCI’s Runoff Capital Framework allows AAC to understand the likely impact of various developments and actions now or in the future on AAC’s capital position thereunder. No changes in AAC’s current management of the business are required by OCI’s Runoff Capital Framework. AAC’s ability to use capital for potential future deleveraging transactions or distributions will require AAC to sustain an excess of risk-adjusted assets over risk-adjusted insured liabilities according to OCI’s Runoff Capital Framework, and to obtain OCI’s approval, and there can be no assurance that OCI will approve any such use of capital. The results of OCI’s Runoff Capital Framework are expected to vary over time based on changes in AAC’s financial position, insured portfolio developments, the impact of strategic actions taken by AAC, the impact of asset/liability management by AAC and, possibly, changes to the inputs and assumptions utilized by OCI. Opportunities for remediating losses on poorly performing insured transactions depend on market conditions, including the perception of AAC’s creditworthiness, the structure of the underlying risk and associated policy as well as other counterparty specific factors. AAC's ability to commute policies or purchase certain investments may also be limited by available liquidity. Ambac Financial Group, Inc 67 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) Settlement of RMBS Litigations and Redemption of Secured Notes: the redemption of the Sitka AAC Note following receipt of the BOA Settlement Payment, was as follows: In October 2022, AAC entered into a Settlement Agreement and Release (the “BOA Settlement Agreement”) with Bank of America Corporation and certain affiliates thereof (together, the “BOA Parties”) pursuant to which the BOA Parties paid AAC the sum of $1,840 (the “BOA Settlement Payment”) following the dismissal of AAC’s lawsuits against the BOA Parties concerning certain residential mortgage-backed securities (“RMBS”) trusts, and the withdrawal by AAC of its objections, including any pending appeals, concerning the settlements that were the subject of certain trust instructional proceedings. In exchange for the BOA Settlement Payment, AAC, on its own behalf and on behalf of its affiliates, agreed to release the BOA Parties and related parties (the “Released Parties”) from claims asserted or which could have been asserted in AAC’s pending litigations against the BOA Parties as well as claims that AAC and its affiliates ever had, may currently have or may have in the future against the Released Parties, subject to certain limited exceptions. The BOA Settlement Agreement also requires AAC to dismiss other pending claims against the Released Parties, and to generally refrain from, and in certain situations hold the Released Parties harmless with respect to, certain actions taken by AAC with respect to RMBS trusts created prior to the date of the BOA Settlement Agreement involving the Released Parties. The BOA Settlement Payment included recoveries from litigations for alleged breaches of contractual obligations and fraud by the BOA Parties. Management allocated the BOA Settlement Payment to each of the litigations based on previously developed valuations of each individual litigation. The portion of the BOA Settlement Payment allocated to fraud litigation recoveries has been recorded as a litigation recovery in the Statement of Comprehensive Income (Loss). On December 29, 2022, AAC entered into a Settlement Agreement and Release (the “Nomura Settlement Agreement”) with Nomura Credit & Capital, Inc. (“Nomura”) to settle its litigation against Nomura concerning certain RMBS trusts (the “Trusts”). Pursuant to the Nomura Settlement Agreement, Nomura made a cash payment to AAC of $140 (the "Nomura Settlement Payment"), and AAC and Nomura agreed to release each other and their respective affiliates and related persons from any claims relating to the Trusts, the financial guaranty policies issued by AAC in connection with Trusts (other than AAC’s obligations to pay insurance claims under such policies), the securities related to the Trusts, and the mortgage loans related to the Trusts. The Nomura Settlement Payment received in January 2023 reduced the subrogation recoverable asset on the Consolidated Balance Sheet. During 2022 and 2023, AAC wholly redeemed its secured debt, in accordance with the terms of such debt, utilizing the BOA Settlement Payment, the Nomura Settlement Payment and other resources as further discussed in Note 12.

BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES Ambac’s consolidated financial statements have been prepared on the basis of U.S. generally accepted accounting principles (“GAAP”). The preparation of in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses and disclosures. There can be no assurance that actual results will conform to such estimates and any future changes in estimates could be material to the financial statements. financial statements Consolidation The consolidated financial statements include the accounts of AFG and all other entities in which AFG (directly or through its subsidiaries) has a controlling financial interest, including variable interest entities (“VIEs”) for which AFG or an AFG subsidiary is deemed the primary beneficiary in accordance with the Consolidation Topic of the Accounting Standards Codification ("ASC"). All significant intercompany balances have been eliminated. The usual condition for a controlling financial interest is ownership of a majority of the voting interests of an entity. However, a controlling financial interest may also exist in entities, such as VIEs, through arrangements that do not involve controlling voting interests. A VIE is an entity: a) that lacks enough equity investment at risk to permit the entity to finance its activities without additional subordinated financial support from other parties; or b) where the group of equity holders does not have: (1) the power, through voting rights or similar rights, to direct the activities of an entity that most significantly impact the entity’s economic performance; (2) the obligation to absorb the entity’s expected losses; or (3) the right to receive the entity’s expected residual returns. The determination of whether a variable interest holder is the primary beneficiary involves performing a qualitative analysis of the VIE that includes, among other factors, its capital structure, contractual terms including the rights of each variable interest holder, the activities of the VIE, whether the variable interest holder has the power to direct the activities of a VIE that most significantly impact the VIE’s economic performance, whether the variable interest holder has the obligation to absorb losses of the VIE that could potentially be significant to the VIE or the right to receive benefits from the VIE that could potentially be significant to the VIE, related party relationships and the design of the VIE. An entity that is deemed the primary Ambac Financial Group, Inc 68 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) beneficiary of a VIE is required to consolidate the VIE. See Note 11. Variable Interest Entities, for a detailed discussion of Ambac’s involvement in VIEs, Ambac’s methodology for determining whether Ambac is required to consolidate a VIE and the effects of VIEs being consolidated and deconsolidated. AFG Unconsolidated Financial Information Financial information of AFG is presented in Schedule II in this Annual Report on Form 10-K as of December 31, 2023 and 2022 and for the years ended December 31, 2023, 2022 and 2021. Investments in subsidiaries are accounted for using the equity method of accounting in Schedule II. Measurement of Credit Losses on Financial Instruments (CECL) Ambac measures credit losses on financial assets that are not accounted for at fair value through net income in accordance with the Current Expected Credit Loss standard or "CECL". • The CECL impact on available-for-sale debt securities is discussed in the Investments sub-section below. • The CECL impact on amortized cost assets, including contract assets and receivables accounted for under the ASC 606 revenue recognition standard, is addressed in the Premiums, Reinsurance Recoverables, Loans and Revenue Recognition sub-sections below. These amortized cost assets reflect management's current estimate of all expected lifetime credit losses. The estimate of expected lifetime credit information, current information, as well as reasonable and supportable forecasts. Expected lifetime credit losses for amortized cost assets are recorded as an allowance for credit losses, with subsequent the allowance reflected in net income each period. losses considers historical increases or decreases in CECL does not apply to subrogation recoveries of previously paid and unpaid losses on insurance contracts accounted for under ASC 944 nor does it apply to equity method investments accounted for under ASC 323. Investments The Investments—Debt Securities Topic of the ASC requires that all debt instruments be classified in Ambac’s Consolidated Balance Sheets according to their purpose and, depending on that classification, be carried at either cost or fair market value. Ambac’s non-VIE debt investment portfolio is accounted for on a trade-date basis and consists primarily of: trading as defined by • Investments in fixed maturity securities are either classified the as available-for-sale or Investments—Debt Securities Topic of the ASC. Available-for-sale debt securities are reported in the financial statements at fair value with unrealized gains and losses, net of deferred taxes, reflected in Accumulated Other Comprehensive Income (Loss) in Stockholders’ Equity and computed using amortized cost as the basis. For purposes of computing amortized cost, premiums and discounts are accounted for using the effective interest method over the term of the security. For structured debt securities with a large underlying pool of homogenous loans, such as mortgage-backed and asset-backed securities, premiums and discounts are adjusted for the effects of actual and anticipated prepayments. For other fixed maturity securities, such as corporate and municipal bonds, discounts are amortized or accreted over the remaining term of the securities and premiums are amortized to the earliest call date. Investments in fixed maturity securities classified at trading are reported in the financial statements at fair value with unrealized gains and losses included in Net investment income on the Statement of Total Comprehensive Income (Loss). • Equity interests in pooled investment funds which are accounted for in accordance with the Investments - Equity Securities Topic of the ASC and reported as Other investments on the Consolidated Balance Sheet with income reported through Net investment income on the Statement of Total Comprehensive Income (Loss). Equity interests in the form of common stock or in-substance common stock are classified as trading securities and reported at fair value while limited partner interests in such funds are reported using the equity method. • Preferred equity investments that do not have readily determinable fair values and are carried at cost, less any impairments as permitted under the Investments—Equity Securities Topic of the ASC. VIE investments in fixed maturity securities are carried at fair value as they are classified as either available-for-sale or trading as defined by the Investments—Debt Securities Topic of the ASC, or accounted for under the fair value option election. For additional information about VIE investments, including fair value by asset-type, see Note 11. Variable Interest Entities. for pooled Fair value is based primarily on quotes obtained from independent market sources. When quotes for fixed maturity reasonably securities are not available or cannot be corroborated, valuation models are used to estimate fair value. These models include estimates, made by management, which utilize current market information. When fair value is not readily determinable the investments are valued using net asset value ("NAV") as a practical expedient as permitted under the Fair Value Measurement Topic of the ASC. Investment valuations could differ materially from amounts that would actually be realized in the market. Realized gains and losses on the sale of investments are determined on the basis of specific identification. Refer to Note 5. Fair Value Measurements for further description of the methodologies used to determine the fair value of investments, including model inputs and assumptions where applicable. investment funds, Ambac has a formal impairment review process for fixed maturity available-for-sale securities in its investment portfolio. Ambac conducts a review each quarter to identify and evaluate investments that have indications of impairment in accordance with the Investments - Debt Securities Topic of the ASC. If management either: (i) has the intent to sell its investment in an impaired debt security or (ii) determines that the Company Ambac Financial Group, Inc 69 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) more likely than not will be required to sell the debt security before its anticipated recovery of the amortized cost basis less any current period credit impairment, then an impairment charge is recognized in earnings, with the amortized cost of the security written-down to fair value. If management does not intend to sell, or will not be required to sell the debt security, the security is reviewed for credit impairment. Factors considered to identify and assess securities for credit impairment include: (i) fair values that have declined by 20% or more below amortized cost; (ii) recent downgrades by rating agencies; (iii) the financial condition of the issuer and financial guarantor, as applicable, and an analysis of projected defaults on the underlying collateral; and (iv) whether scheduled interest payments are past due. The recognition of credit impairment losses for available-for-sale debt securities are recorded as an allowance for credit losses with an offsetting charge to net income. Improvements to estimated credit losses for available-for-sale debt securities are recognized immediately in net income. If we believe a decline in the fair value of a particular fixed maturity available-for-sale investment is not credit impaired, we record the decline as an unrealized loss net of tax in Accumulated Other Comprehensive Income (Loss) in Stockholders’ Equity on our Consolidated Balance Sheets. impairment The evaluation of securities for credit is a quantitative and qualitative process, which is subject to risks and uncertainties and is intended to determine whether, and to what extent, declines in the fair value of investments should be recognized risks and in current period earnings. The uncertainties include changes in general economic conditions, the issuer’s or guarantor’s financial condition and/or future prospects, the impact of regulatory actions on the investment portfolio, the performance of the underlying collateral, the effects of changes in interest rates or credit spreads and the expected recovery period. With respect to Ambac insured securities owned, future cash flows used to measure credit impairment represents the sum of (i) the bond’s intrinsic cash flows and (ii) the estimated AAC claim payments. Ambac’s assessment about whether a decline in value is considered a credit impairment reflects management’s current judgment regarding facts and circumstances specific to a security and the factors noted above. If that judgment changes, Ambac may ultimately record a charge for credit impairment in future periods. Ambac has made certain accounting policy elections related to interest receivable ("AIR") for available-for-sale accrued investments under CECL. Elections include: i) not measuring AIR for credit impairment, instead AIR is written off when it becomes 90 days past due; ii) writing off AIR by reversing interest income; iii) presenting AIR separately in Other Assets on the balance sheet and iv) excluding AIR from amortized cost balances in required CECL disclosures found in Note 4. Investments. AIR at December 31, 2023 and 2022 was $14 and $10, respectively. Refer to Note 4. Investments for further credit impairment disclosures. Premiums Legacy Financial Guarantee Insurance the cash amount received. For Gross premiums were received either upfront or in installments. For premiums received upfront, an unearned premium revenue (“UPR”) liability was established, which was initially recorded as installment premium transactions, a premium receivable asset and offsetting UPR liability was initially established in an amount equal to: (i) the present value of future contractual premiums due (the “contractual” method) or (ii) if the underlying insured obligation is a homogenous pool of assets which are contractually prepayable, the present value of premiums to be collected over the expected life of the transaction (the “expected” method). An appropriate risk-free rate corresponding to the weighted average life of each policy and currency is used to discount the future premiums contractually due or expected to be collected. For example, U.S. dollar exposures are discounted using U.S. Treasury rates while exposures denominated in a foreign currency are discounted using the appropriate risk-free rate for the respective currency. The weighted average risk-free rate at December 31, 2023 and 2022, was 3.2%. and 3.0%, the weighted average period of future respectively, and the premium receivable at to estimate premiums used December 31, 2023 and 2022, was 7.7 years and 8.0 years, respectively. include Insured obligations consisting of homogeneous pools for which Ambac uses expected future premiums to estimate the premium receivable residential mortgage-backed securities ("RMBS"). As prepayment assumptions change for homogenous pool transactions, or if there is an actual prepayment for a “contractual” method related premium receivable and UPR are adjusted in equal and offsetting amounts with no immediate effect on earnings using new premium cash flows and the then current risk-free rate corresponding to the initial weighted average life of the related policy. transaction, installment the to in proportion For both upfront and installment premium policies, premium revenues are earned over the life of the financial guarantee contract insured principal amount the outstanding at each reporting date (referred to as the level-yield the premium installment paying policies, method). For receivable discount, equating to the difference between the undiscounted future installment premiums and the present value of future installment premiums, is accreted as premiums earned in proportion to the premium receivable balance at each reporting date. When a bond issue insured by Ambac has been retired early, typically due to an issuer call, any remaining UPR is recognized at that time to the extent the financial guarantee contract is legally extinguished, causing accelerated premium revenue. For installment premium paying the recognition of any remaining UPR by the reduction of the related premium receivable to zero (as it will not be collected as a result of the retirement), which may cause negative accelerated premium revenue. Certain obligations insured by Ambac have been legally defeased whereby government securities are purchased by the issuer with the proceeds of a new bond transactions, we offset Ambac Financial Group, Inc 70 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) issuance, or less frequently with other funds of the issuer, and held in escrow. The principal and interest received from the escrowed securities are then used to retire the Ambac-insured obligations at a future date either to their maturity date (a refunding) or a specified call date (a pre-refunding). Ambac has evaluated the provisions in policies issued on these obligations and determined those insurance policies have not been legally extinguished. For policies with refunding securities, premium revenue recognition is not impacted as the escrowed maturity date is the same as the previous legal maturity date. For policies with pre-refunding securities, the maturity date of the pre- refunded security has been shortened from its previous legal maturity. Although premium revenue recognition has not been accelerated in the period of the pre-refunding, it results in an increase in the rate at which the policy's remaining UPR is to be recognized. For financial guarantee contracts, the issuer's ability and willingness to pay its insured debt obligation impacts the payment of policy losses by Ambac as well as the receipt of premiums from the issuer. As such, management leverages its existing loss reserve estimation process to evaluate credit impairment for premium receivables. Key factors in assessing credit impairment include historical premium collection data, internal risk classifications, credit ratings and loss severities. For structured finance involving special purpose entities, we further evaluate the priority of premiums paid to Ambac within the contractual waterfall, as required by bond indentures. Ambac has a formal quarterly credit impairment review process for premium receivables. transactions Management utilizes either a discounted cash flow ("DCF") or probability of default/loss given default ("PD/LGD") approach to estimate credit impairment on premium receivables. The DCF approach utilizes expected cash flows developed by Ambac's Risk Management Group using the same (or similar) models used for estimating loss reserves where such models can identify shortfalls in premiums. Credit impairment using the DCF approach is equal to the difference between amortized cost and the present value of expected cash flows. Credit impairment under the PD/LGD approach is the product of (i) the premium receivable carrying value, (ii) internally developed default probability (considering internal ratings and average life), and (iii) internally developed loss severities. Refer to Note 7. Insurance Contracts for further credit impairment disclosures. AAC has reinsurance in place pursuant to surplus share treaties and facultative reinsurance agreements. Similar to gross premiums, premiums ceded to reinsurers were paid either upfront or in installments. For premiums paid upfront, a deferred ceded premium asset was established which is initially recorded as the cash amount paid. For installment premiums, a ceded premiums payable liability and offsetting deferred ceded premium asset were initially established in an amount equal to: i) the present value of future contractual premiums due or ii) if the underlying insured obligation is a homogenous pool of assets, the present value of expected premiums to be paid over the life of the transaction. An appropriate risk-free rate corresponding to the weighted average life of each policy and exposure currency is used to discount the future premiums contractually due or expected to be collected. Premiums ceded to reinsurers reduce the amount of premiums earned by Ambac from its financial guarantee insurance policies. For both upfront and installment premiums, ceded premiums written are primarily recognized in earnings in proportion to and at the same time as the related gross premium revenue is recognized. For premiums paid to reinsurers on an installment basis, Ambac records the present value of future ceding commissions as an offset to ceded premiums payable, using the same assumptions noted above for installment premiums. Specialty Property and Casualty Insurance terms applied against Gross written premiums on insurance policies are recorded at the inception of the policy and can be received on an upfront or installment basis. Ceded premiums written are based on contractual related gross written premiums. Premiums, net of reinsurance, are recognized as revenue on a daily pro-rata basis over the term of the insured risk. Unearned premiums and Deferred ceded premiums represents the portion of gross and ceded premiums written that relate to unexpired risk, respectively. Premium receivables represent balances currently due and amounts not yet due from policyholders, insurance carriers, managing general agents or producers issuing insurance policies on Everspan's behalf. Premium receivables are reported net of an allowance for expected credit losses. The allowance is based upon Everspan's ongoing review of amounts outstanding, including delinquencies and write-offs, and other relevant factors. Credit risk is partially mitigated by the managing general agent's ability to cancel the policy on behalf of Everspan if the policyholder does not pay the premium, thereby reducing the related policy's premium written and Everspan's premium receivable. Loans Loans are reported at either their outstanding principal balance less unamortized discount or at fair value. • Loans not held by consolidated VIEs are reported at their outstanding principal balance less unamortized discount and are reported within Other assets on the Consolidated Balance Sheet. Interest income is earned using the effective interest method based upon interest accrued on the unpaid principal balance adjusted for accretion of discounts. A loan is considered impaired when, based on the financial condition of the borrower, it is probable that Ambac will be unable to collect all principal and interest due according to the contractual terms of the loan agreement. Ambac has a formal quarterly credit impairment review process for these loans. The key factors in assessing credit impairment are internal credit ratings and loss severities. Management utilizes a PD/LGD approach, similar to the one described above for financial guarantee premium receivables, which is applied to the loan carrying value. • Loans held by VIEs consolidated as required under the Consolidation Topic of the ASC are carried at fair value under the fair value option election with changes in fair value recorded in Income (loss) on variable interest entities Ambac Financial Group, Inc 71 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) on the Consolidated Statements of Total Comprehensive Income (Loss). Such loans are reported as Loans, at fair value within the Variable interest entity assets section of the Consolidated Balance Sheet. Derivative Contracts The Company has entered into derivative contracts primarily to hedge certain economic risks inherent in its asset and liability portfolios. None of Ambac’s derivative contracts were designated as hedges under the Derivatives and Hedging Topic of the ASC. Ambac's derivatives have consisted primarily of interest rate swaps and futures contracts. • Ambac's current derivatives portfolio consists of certain legacy interest rate swaps executed in connection with financial guarantee client financings. In recent years, Ambac's interest rate derivatives portfolio consisted primarily of interest rate swaps and futures contracts to economically hedge interest rate risk in the financial guarantee and investment portfolios, managed on the basis of its net sensitivity to changes in interest rates. The economic hedge positions of the portfolio were fully exited in early 2023. Changes in the fair value of these interest rate derivatives are recorded, along with changes in fair value of other derivative contracts, within Net gains (losses) on derivative contracts on the Consolidated Statements of Total Comprehensive Income (Loss). • VIEs consolidated under the Consolidation Topic of the ASC entered into derivative contracts to meet specified purposes within their securitization structure. Changes in fair value of consolidated VIE derivatives are included within Income (loss) on variable interest entities on the Consolidated Statements of Total Comprehensive Income (Loss). All derivatives are recorded on the Consolidated Balance Sheets at fair value on a gross basis; assets and liabilities are netted by counterparty only when a legal right of offset exists, and are included in Other assets and Other liabilities, respectively. Variation payments on centrally cleared swaps and futures contracts are considered settlements of the associated derivative balances and are reflected as a reduction to derivative liabilities or assets on the Consolidated Balance Sheets. For other derivatives, Ambac has determined that the amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral may not be used to offset amounts due under the derivative instruments in the normal course of settlement. Therefore, such amounts are not offset against fair value amounts recognized for derivative instruments executed with the same counterparty under the same master netting arrangement and are included in Other assets on the Consolidated Balance Sheets. Refer to Note 9. Derivative Instruments for further discussion of the Company’s use of derivative instruments and their impact of the consolidated financial statements. Refer to Note 5. Fair Value Measurements for further description of the methodologies used to determine the fair value of derivative contracts, including model inputs and assumptions where applicable. Deferred Acquisition Costs, Ceding Commissions and Deferred Program Fees The Specialty Property and Casualty Program business defers acquisition costs incurred that are related directly to the successful acquisition of new or renewal insurance contracts, including commissions paid to managing general agents for direct business, and paid to insurance carriers when acquired via assumed reinsurance. Ceding commissions received from reinsurers represent a recovery of related acquisition costs. Deferred acquisition costs, net of ceding commissions, are amortized over the related policy period, generally one year, and recognized in amortization of deferred acquisition costs. Ceding commissions received in excess of the related direct acquisition costs are deferred and amortized over the related policy period, and recognized as program fees. Goodwill Goodwill is attributable to acquisitions in the Insurance Distribution segment and represents the acquisition cost in excess of the fair value of net assets acquired, including identifiable intangible assets. Goodwill is assigned at acquisition to the applicable reporting unit of the acquired entity giving rise to the goodwill. Goodwill is not amortized but is subject to impairment testing. Goodwill impairment tests are performed annually or more frequently if circumstances indicate a possible impairment. The annual test of goodwill impairment is as of October 1st of each year. Depending on the reporting unit, management utilizes one of two approaches for impairment testing. Under the first approach, qualitative factors are first assessed to determine if it is more likely than not that the fair value of the reporting unit is less than its carrying amount. If it is more likely than not, then a quantitative impairment evaluation is performed. Under the second approach, management bypasses the qualitative evaluation and proceeds directly the quantitative evaluation. The quantitative evaluation under both of the above approaches compares the estimated fair value of the reporting unit with its carrying value (including goodwill and identifiable intangible assets). An impairment is recognized for the excess of the carrying amount of the reporting unit over it estimated fair value. If the reporting unit’s estimated fair value exceeds its carrying value, goodwill is not impaired. There have been no accumulated impairment losses since this goodwill was established. to Intangible Assets Financial Guarantee Insurance intangible Upon Ambac's emergence from bankruptcy in 2013, an insurance intangible asset was recorded which represented the difference between the fair value and aggregate carrying value of the financial guarantee insurance and reinsurance assets and liabilities. The carrying values of financial guarantee insurance and reinsurance contracts continue to be reported and measured in accordance with their existing accounting policies. Pursuant to the Financial Services-Insurance Topic of the ASC, the insurance intangible is to be measured on a basis consistent with the related financial guarantee insurance and reinsurance contracts. The initial insurance intangible asset was assigned to groups of insurance and reinsurance contracts with similar Ambac Financial Group, Inc 72 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) characteristics and has been amortized using a level-yield method based on par exposure of the related groups. Finite-lived intangibles Ambac acquired identifiable intangible assets attributable to the Insurance Distribution segment. The intangible assets primarily relate to distribution relationships, non-compete agreements and trade names, all of which have finite lives and are amortized over their estimated useful lives using the straight-line method. The Company tests finite-lived acquired intangible assets for impairment if certain events occur or circumstances change indicating that the carrying amount of the intangible asset may not be recoverable. The carrying amount of the intangible asset is not recoverable if it exceeds the projected undiscounted cash flows expected to result from the use and eventual disposal of the asset or asset group. If deemed unrecoverable, an impairment loss is recognized for the excess carrying amount over the fair value. There have been no accumulated impairment losses since these finite-lived intangible assets were established. Indefinite-lived intangibles Ambac acquired identifiable intangible assets attributable to its acquisitions of carriers in both 2021 and 2022, which were accounted for as asset acquisitions (Specialty Property and Casualty Insurance segment). The intangible assets relate to insurance licenses which have indefinite lives and therefore are not amortized. The useful lives are re-evaluated each period to determine whether facts and circumstances continue to support an indefinite life. The Company tests indefinite-lived acquired intangible assets for impairment annually or more frequently if circumstances indicate a possible impairment. Ambac tests indefinite-lived intangibles for impairment as of October 1st of each year. If, after assessing qualitative factors, management believes it is more likely than not that the intangible assets are impaired, a quantitative impairment evaluation is performed. Management also has the option to bypass the qualitative evaluation and proceed directly to the quantitative evaluation. The quantitative test compares the estimated fair value of the intangible asset with its carrying value. An impairment is recognized for the excess of the carrying amount of the intangible asset over it estimated fair value. If the asset’s estimated fair value exceeds its carrying value, the intangible asset is not impaired. There have been no accumulated impairment losses since these indefinite-lived intangible assets were established. Restricted Cash Cash that we do not have the right to use for general purposes is recorded as restricted cash in our consolidated balance sheets. Restricted cash includes (i) consolidated variable interest entity cash restricted to support the obligations of the consolidated VIEs and (ii) fiduciary cash held by Ambac's insurance distribution subsidiaries as described below. Fiduciary Funds As an intermediary, we hold funds, generally in a fiduciary capacity, for the account of third parties, typically as the result of premiums received from retail brokers or insureds that are in transit to insurers and claims due that are in transit from insurers. Since fiduciary assets are not available for corporate use, they are shown in the consolidated balance sheets as restricted cash and we present an equal and corresponding fiduciary liability relating to these funds representing amounts or claims or premiums due on our consolidated balance sheets (included in Other liabilities). Fiduciary funds are generally required to be kept in bank accounts subject to guidelines which emphasize capital preservation and liquidity. The Company is entitled to retain investment income earned on certain of these fiduciary funds in accordance with industry custom and practice and, in some cases, as supported by agreements with insureds. Restricted cash for net uncollected premiums and claims and the related fiduciary liabilities were $12 and $14 at December 31, 2023 and 2022, respectively. Loss and Loss Adjustment Expenses Legacy Financial Guarantee The loss and loss adjustment expense reserve (“loss reserve”) policy relates only to Ambac’s non-derivative financial guarantee insurance business for insurance policies issued to beneficiaries, including VIEs, for which we do not consolidate the VIE. Losses and loss expenses are based upon estimates of the ultimate aggregate losses inherent in the insured portfolio as of the reporting date. The policy for derivative contracts is discussed in the “Derivative Contracts” section above. A loss reserve is recorded on the balance sheet on a policy-by- policy basis based upon the present value ("PV") of expected net claim cash outflows or expected net recovery cash inflows, discounted at risk-free rates. The estimate for future net cash flows consider the likelihood of all possible outcomes that may occur from missed principal and/or interest payments on the insured obligation. This estimate also considers future recoveries related to remediation strategies and other contractual or subrogation-related cash flows. • Net claim cash outflow policies represent contracts where the PV of expected cash outflows are greater than the PV of expected recovery cash inflows. For such policies, a “loss and loss adjustment expense reserves” liability is recorded for the excess of the PV of expected net claim cash outflows over the unearned premium revenue. • Net recovery cash inflow policies represent contracts where the PV of expected recovery cash inflows are greater than the PV of expected claim cash outflows. For such policies, a “Subrogation recoverable” asset is recorded. The evaluation process for determining expected losses is subject to certain judgments based on our assumptions regarding the probability of default by the issuer of the insured security, probability of settlement outcomes (which may include commutation settlements, refinancing and/or other settlement outcomes) and expected severity of credits for each insurance contract. Ambac’s loss reserves are based on management’s ongoing review of the financial guarantee credit portfolio. Active surveillance of the insured portfolio enables Ambac’s Risk Management Group ("RMG") to track credit migration of Ambac Financial Group, Inc 73 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) insured obligations from period to period and update internal classifications and credit ratings for each transaction. Non- adversely classified credits are assigned a Class I rating while adversely classified credits are assigned a rating of Class IA through Class V. The criteria for an exposure to be assigned an adversely classified credit rating includes the deterioration of an issuer’s financial condition, underperformance of the underlying transactions such as collateral mortgage-backed or securitizations), poor performance by the servicer of the underlying collateral and other adverse economic events or trends. The servicer of the underlying collateral of an insured securitization transaction is a consideration in assessing credit quality because the servicer’s performance can directly impact the performance of the related issue. (for collateral dependent loan student All credits are assigned risk classifications by RMG using the following guidelines: CLASS I – “Fully Performing - Meets Ambac Criteria with Remote Probability of Claim” - Credits that demonstrate adequate security and structural protection with a strong capacity to pay interest, repay principal and perform as underwritten. Factors supporting debt service payment and performance are considered unlikely to change and any such change would not have a negative impact upon the fundamental credit quality. Through ongoing surveillance, Ambac may also designate Class I credits into one or more of the following categories: • Survey List - credits that may lack information or demonstrate a weakness but further deterioration is not expected. • Watch List - credits that demonstrate the potential for future material adverse development due to such factors as long-term uncertainty about a particular sector, a certain structural element, large exposure concentration or concern related to the issuer or transaction or the overall financial and economic sustainability. CLASS IA – “Potential Problem with Risks to be Dimensioned” - Credits that are fully current and monetary default or claims- payment are not anticipated. The issuer’s financial condition may be deteriorating or the credits may lack adequate collateral. A structured financing may also evidence weakness in its fundamental credit quality as evidenced by its under- performance relative to its modeled projections at underwriting, issues related to the servicer’s ability to perform or questions about the structural integrity of the transaction. While certain of these credits may still retain an investment grade rating, they usually have experienced or are vulnerable to a ratings downgrade. Further investigation is required to dimension and correct any deficiencies. A complete legal review of documents may be required. An action plan should be developed with triggers for future classification changes upward or downward. CLASS II – “Substandard Requiring Intervention” - Credits whose fundamental credit quality has deteriorated to the point that timely payment of debt service may be jeopardized by adversely developing trends of a financial, economic, structural, managerial or political nature. No claim payment is currently foreseen but the probability of loss or claim payment over the life of the transaction is now existent (generally 10% or greater probability). Class II credits may be border-line or below investment grade (BBB- to B). Prompt and sustained action must be taken to execute a comprehensive loss mitigation plan and correct deficiencies. CLASS III – “Doubtful with Clear Potential for Loss” - Credits whose fundamental credit quality has deteriorated to the point that timely payment of debt service has been or will be jeopardized by adverse trends of a financial, economic, structural, managerial or political nature which, in the absence of positive change or corrective action, are likely to result in a loss. The probability of monetary default or claims paying over the life of the transaction is generally 50% or greater. Full exercise of all available remedial actions is required to avert or minimize losses. Class III credits will generally be rated below investment grade (B to CCC). CLASS IV – “Imminent Default or Defaulted” - Monetary default or claim payments have occurred or are expected imminently. Class IV credits are generally rated D. CLASS V – “Fully Reserved” - The credit has defaulted and payments have occurred. The claim payments are scheduled and known, reserves have been established to fully cover such claims, and no claim volatility is expected. The population of credits evaluated in Ambac’s loss reserve process are: (i) all adversely classified credits and ii) non- adversely classified credits which had an internal Ambac rating downgrade since the transaction’s inception. One of two approaches is then utilized to estimate losses to ultimately determine if a loss reserve should be established. • The first approach is a statistical expected loss approach, which considers the likelihood of all possible outcomes. The “base case” statistical expected loss is the product of: (i) the par outstanding on the credit; (ii) internally developed default information (taking into consideration internal ratings and average life of an obligation); (iii) internally developed loss severities; and (iv) a discount factor. The loss severities and default information are based on rating agency information, are specific to each bond type and are established and approved by senior RMG officers. For certain credit exposures, Ambac’s additional monitoring, loss remediation efforts and probabilities of potential settlement outcomes may provide information relevant to adjust this estimate of “base case” statistical expected the “base case” statistical expected loss as the best estimate of expected loss or assign multiple probability weighted scenarios to determine an adjusted statistical expected loss that better reflects management’s view of a given transaction’s expected losses, as well as the potential for additional remediation activities (e.g., commutations). losses. RMG may accept • The second approach entails the use of cash-flow based models to estimate expected losses (future claims, net of potential recoveries, expected to be paid to the holder of the insured financial obligation). Ambac’s RMG group will consider the likelihood of all possible outcomes and Ambac Financial Group, Inc 74 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) develop appropriate cash flow scenarios. This approach can include the utilization of internal or third party models and tools to project future losses and resultant claim payment estimates. We utilize cash flow models for RMBS, student loans and other exposures. RMBS and student loan models use historical performance of the collateral pools in order to then derive future performance characteristics, such as default and voluntary prepayment rates, which in turn determine projected future claim payments. In other cases, such as many public finance exposures we do not specifically forecast resources available to pay debt service in the cash flow model itself. Rather, we consider the issuers’ overall ability and willingness to pay, including the fiscal, economic, legal and political framework to develop projected future claim payment estimates. In this approach, a probability-weighted expected loss estimate is developed based on assigning probabilities to multiple claim payment scenarios and applying an appropriate discount factor. Additionally, we consider the issuer’s ability to refinance an insured issue, Ambac’s ability to execute a potential settlement (i.e., commutation) of the insurance policy, including the impact on future installment premiums, and/ or other restructuring possibilities in our scenarios. The commutation scenarios and the related probabilities of occurrence vary by transaction, depending on our view of the likelihood of negotiating such a transaction with issuers and/or investors. The discount factor applied to the statistical expected loss approach is based on a risk-free discount rate corresponding to the remaining expected weighted-average life of the exposure and the exposure currency. For the cash flow scenario approach, discount factors are applied based on a risk-free discount rate term structure and correspond to the date of each respective cash flow payment or recovery and the exposure currency. Discount factors are updated for the current risk-free rate each reporting period. Ambac establishes loss expense reserves based on our estimate of expected net cash outflows for loss expenses, such as legal and consulting costs. Below we provide further details of our loss reserve models for both RMBS and student loan exposures: RMBS Expected Loss Estimate Ambac insures RMBS transactions collateralized by (i) first-lien mortgages; and (ii) second-lien mortgage loans such as closed- end seconds and home equity lines of credit. If the borrower defaults on the payments due under these loans and the property is subsequently liquidated, the liquidation proceeds are first utilized to pay off the first-lien loan (as well as other costs) and any remaining funds are applied to pay off the second-lien loan. As a result of this subordinate position to the first-lien loan, second-lien loans may carry a significantly higher severity in the event of a loss. Ambac primarily utilizes a cash flow model (“RMBS cash flow model”) to develop estimates of projected losses for both our first and second lien transactions. The RMBS cash flow model projects collateral performance utilizing a combination of historical performance along with the most recent loan status information to project future collateral performance. In addition to the base case, we analyze historical volatility of performance to develop stress and upside cases. The highest probability is assigned to the base case, with lower probabilities to the stress and upside cases. For the liabilities of the transaction which we insure, we generally utilize waterfall projections generated from a tool provided by a market accepted vendor. This waterfall tool allows us to capture the impact of each transaction’s specific structure (e.g., the waterfall priority of payments, triggers, redemption priority) to generate our specific projected claims profile in the base, upside and downside scenarios. On a monthly basis, we compare monthly claims submitted against the trustees’ reports, waterfall projections and our understanding of the transactions’ structures to identify and resolve discrepancies. In our experience, market performance and model characteristics change and therefore need to be updated and reflected in our models through time. As such, we conduct regular reviews of current models, alternative models and the overall approach to loss estimation. Student Loan Expected Loss Estimate loan insured portfolio consists of credits The student collateralized by private student loans. The calculation of loss reserves for our student loan portfolio involves evaluating numerous factors that can impact ultimate losses. Since our policies cover timely interest and ultimate principal payment, our loss projections must make assumptions for many factors covering a long horizon. Key assumptions that will impact ultimate losses include, but are not limited to, the following: collateral performance (which is highly correlated to the economic environment); interest rates; operating risks associated with the issuer, servicers, special servicers, and administrators; investor appetite insured obligations; and as applicable, Ambac’s ability and willingness to commute policies. In addition, we consider in our student loan loss projections the potential impact, if any, of proposed or final regulatory actions or orders, including by the Consumer Financial Protection Bureau ("CFPB"), affecting our insured transactions. tendering or commuting for We develop and assign probabilities to multiple cash flow scenarios based on each transaction’s unique characteristics. Probabilities assigned are based on available data related to the credit, information from contact with the issuer (if applicable), and any economic or market information that may impact the outcomes of the various scenarios being evaluated. Our base case usually projects deal performance out to maturity using expected loss assumptions. As appropriate, we also develop other cases that incorporate various upside and downside scenarios that may include changes to defaults and recoveries.

AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) Specialty Property and Casualty Loss and loss adjustment expense reserves for Specialty Property and Casualty policies represent management's estimate of the ultimate liability for unpaid losses and loss expenses for claims that have been reported and claims that have been incurred but not yet reported ("IBNR") as of the balance sheet date. the liability, but Loss and loss adjustment expense reserves do not represent an instead represent exact calculation of management estimates, primarily utilizing actuarial expertise and projection methods that develop estimates for the ultimate cost of claims and claim adjustment expenses. The reserves are estimated based upon experience and using a variety of actuarial methods. These estimates are reviewed and are subject to the impact of future changes in factors such as claim severity and frequency, underwriting and claims practices, changes in social and economic conditions including the impact of inflation, legal and judicial developments, medical cost trends and upward trends in damage awards. Our actuarial methods may also rely on external data, such as industry loss ratios, loss development factors, or trend factors. Such data while more mature than Everspan's own data may not be perfectly representative of the particular business written by Everspan. The ultimate amount for loss and loss adjustment expenses may be in excess, or less than, the amounts recorded on our financial statements. Because the establishment of claims and claim adjustment expense reserves is an inherently uncertain process involving estimates and judgment, currently estimated claims and claim adjustment expense reserves may change. Adjustments will be reflected as part of the net increase or reduction in loss and loss adjustment expense reserves in the periods in which they become known. Cumulative amounts paid and case reserves held as of the balance sheet date are subtracted from the estimate of the ultimate cost of claims and claim adjustment expenses to derive incurred but not reported (IBNR) reserves. There were no changes in methodology in the past year. Detailed claim data is typically insufficient to produce a reliable indication of the initial estimate for ultimate claims and claim adjustment expenses for an accident year. As a result, the initial estimate for an accident year is generally based on an exposure- based method using the loss ratio projection method. The loss ratio projection method develops an initial estimate of ultimate claims and claim adjustment expenses for an accident year by multiplying earned premium for the accident year by a projected loss ratio. The projected loss ratio is determined by analyzing prior period experience, and adjusting for loss cost trends, rate level differences, mix of business changes and other known or observed factors influencing the accident year relative to prior accident years. For prior accident years, the following estimation and analysis methods are principally used by the Company’s actuaries to estimate the ultimate cost of claims and claim adjustment expenses. These estimation and analysis methods are typically referred to as conventional actuarial methods. • The paid loss development method assumes that the future change (positive or negative) in cumulative paid losses for a given cohort of claims will occur in a stable, predictable pattern from year-to-year, consistent with the pattern observed in past cohorts. • The case incurred development method is the same as the paid loss development method, but is based on cumulative case-incurred losses rather than paid losses. • The Bornhuetter-Ferguson method uses an initial estimate of ultimate losses for a given product line reserve component, typically expressed as a ratio to earned premium. The method assumes that the ratio of additional claim activity to earned premium for that component is relatively stable and predictable over time and that actual claim activity to date is not a credible predictor of further activity for that component. The method is used most often for more recent accident years where claim data is sparse and/or volatile, with a transition to other methods as the underlying claim data becomes more voluminous and therefore more credible. While these are the principal methods utilized, the Company’s actuaries have available to them the full range of actuarial methods developed by the casualty actuarial profession. Most actuarial methods assume that past patterns demonstrated in the data will repeat themselves in the future. The Company performs a continuing review of its loss and loss adjustment expense reserves, including its reserving techniques and the impact of reinsurance. Since the reserves are based on estimates, the ultimate liability may be more or less than such reserves. Reinsurance Recoverable The Company uses ceded reinsurance to transfer certain insurance risk, along with premiums written and earned, to other insurance carriers that agree to share in such risks. The primary purpose of the reinsurance is to (i) protect the Company, at a cost, from losses in excess of amounts it is willing to accept, (ii) protect the Company's capital, and (iii) within the Specialty Property and Casualty Insurance operations, to manage the Company's net retention on individual risks and overall exposure to losses while providing the Company the ability to offer policies with sufficient limits to meet policyholder needs. • Within its Specialty Property and Casualty Insurance segment, the Company generally enters into quota share reinsurance agreements whereby the Company cedes to the capacity providers (reinsurers) a substantial amount (generally 70% or more) of its gross liability under all policies issued by and on behalf of the Company by the MGA/U. Ambac is exposed to the credit risk of the reinsurer, or the risk that one of its reinsurers becomes insolvent or otherwise unable or unwilling to pay policyholder claims. This credit risk is generally mitigated by either selecting well capitalized, highly rated authorized capacity providers or requiring that the capacity provider post collateral to secure the reinsured risks, which in some instances, exceeds the related reinsurance recoverable.

The Company reports its reinsurance recoverables net of an allowance for amounts to be uncollectible. that are estimated The reinsurance of risk does not legally relieve Ambac of its original liability to its policyholders. In the event that any of Ambac’s reinsurers are unable to meet their obligations under reinsurance contracts, Ambac would, nonetheless, be liable to its policyholders for the full amount of its policy. To minimize its credit exposure to losses from reinsurer insolvencies, Ambac (i) is entitled to receive collateral from certain reinsurance counterparties pursuant to the terms of the relevant reinsurance contracts and (ii) has certain cancellation rights that can be exercised by Ambac in the event of rating agency downgrades of a reinsurer (among other events and circumstances). For those reinsurance counterparties that do not reinsurers are well currently post collateral, Ambac’s capitalized, highly rated, authorized capacity providers. Ambac has a formal quarterly credit impairment review process whereby Ambac has elected to use the practical expedient of considering the fair value of collateral posted by reinsurers when evaluating credit impairment. To determine the total unsecured recoverable to be evaluated for credit impairment, Ambac nets the reinsurance recoverable amount by ceded premiums payable and the fair value of collateral posted, if any. The key factors in assessing credit impairment for reinsurance recoverables are independent rating agency credit ratings and loss severities. Management utilizes a probability of default/loss given default ("PD/LGD") approach, which is applied to the net unsecured reinsurance recoverable amount. Refer to Note 7. Insurance Contracts for credit impairment disclosures. Long-term Debt Long-term debt issued by Ambac is carried at par value less unamortized discount. Accrued interest and discount accretion on long-term debt is reported as Interest expense on the Consolidated Statements of Total Comprehensive Income (Loss). To the extent Ambac repurchases or redeems its long- term debt, such repurchases or redemptions may be settled for an amount different than the carrying value of the obligation. Any difference between the payment and carrying value of the obligation is reported in Net realized gains (losses) on extinguishment of debt on the Consolidated Statements of Total Comprehensive Income (Loss). For surplus note repurchases, the pro-rata purchase price related to principal and accrued interest is reported as a financing and operating activity, respectively, on the Statement of Cash Flows. For long-term debt issued by consolidated VIEs in which Ambac's variable interest arises from financial guarantees written by Ambac's subsidiaries ("LFG VIEs"), we may elect to use the fair value option on an instrument by instrument basis. When the fair value option is elected, changes in the fair value of the LFG VIEs' long-term debt is reported within Income (loss) on variable interest entities in the Consolidated Statements of Total Comprehensive Income (Loss), except for the portion of the total change in fair value of financial liabilities caused by changes in the instrument-specific credit risk which is presented separately in Other comprehensive income (loss). In cases where the fair value option has not been elected, the LFG VIEs' long-term debt is carried at par less unamortized discount, with interest expense reported within Income (loss) on variable interest entities in the Consolidated Statements of Total Comprehensive Income (Loss). Noncontrolling Interests Nonredeemable noncontrolling interests At December 31, 2023 and 2022, AAC had 4,596 shares of issued and outstanding Auction Market Preferred Shares ("AMPS") with a liquidation preference of $115 (reported as nonredeemable noncontrolling interest of $51 on Ambac's balance sheet). In 2022, Ambac purchased 905 shares of AMPS for $8. The difference between this amount paid to AMPS holders and the carrying amount was reflected as an increase to for Net approximately $1. The auction occurs every 28 days and the dividend rate has continuously been reset at the maximum, equal to the Reference Rate plus 200 basis points. Beginning July 1, 2023, the Reference Rate for the AMPS is one-month CME Term SOFR plus 0.11448 percent. Prior to July 1, 2023, the Reference Rate was one-month LIBOR. income attributable to common shareholders Under the terms of the AMPS, dividends may not be paid on the common stock of AAC unless all accrued and unpaid dividends on the AMPS for the then current dividend period have been paid, provided, that dividends on the common stock may be made at all times for the purpose of, and only in such amounts as are necessary for, enabling AFG (i) to service its indebtedness for borrowed money as such payments become due or (ii) to pay its operating expenses. If dividends are paid on the common stock as provided in the prior sentence, dividends on the AMPS become cumulative until the date that all accumulated and unpaid dividends have been paid on the AMPS. AAC has not paid dividends on its AMPS since 2010. Redeemable noncontrolling interests The Xchange, All Trans, Capacity Marine and Riverton acquisitions resulted in 80%, 85%, 80% and 80%, respectively, ownership of the acquired entities by Ambac. Under the terms of all the acquisition agreements, Ambac has call options to purchase the remaining interest from the minority owners (i.e., noncontrolling interests) and the minority owners have put options to sell their remaining interests to Ambac. Because the exercise of the put options are outside the control of Ambac, in accordance with the Distinguishing Liabilities from Equity Topic of the ASC, Ambac reports redeemable noncontrolling interests in the mezzanine section of its consolidated balance sheet. The redeemable noncontrolling interest is remeasured each period as the greater of: i. the carrying value under ASC 810, which attributes a portion of consolidated net income (loss) to the redeemable noncontrolling interest, and Ambac Financial Group, Inc 77 2023 Form 10-K AMBAC FINANCIAL GROUP, INC.

The following steps are applied to recognize revenue: (i) identify the contract(s) with the customer, (ii) identify the performance obligations in the contract(s), (iii) determine the transaction price, and (iv) allocate the transaction price to the performance obligations in the contract and recognize revenue when (or as) the entity satisfies a performance obligation. A performance obligation is satisfied either at a point in time or over time depending on the nature of the product or service provided, and the specific terms of the contract with customers. Insurance Distribution Insurance Distribution performance obligations consist of underwriting and placing policies with insurers and, for certain products, providing claims servicing. Revenue from employer stop loss policies ("ESL") is apportioned to policy placement and claims servicing based on the relative stand-alone selling price of the respective performance obligations with policy placement revenue recognized upfront while claims servicing revenue is recognized over the claim adjustment period. Revenue from other insurance policies are recognized up front as no further performance obligations exist after policy placement. Revenue consists of base and profit-sharing commissions. • Base commissions, associated with policy placement and claims servicing, are estimated by applying the contractual commission percentages to estimated gross premiums placed. • Profit-sharing commissions variable consideration associated with policy placement only and are estimated based on expected loss ratios and the estimated gross premium for base commissions. represent Base and profit-sharing commissions are estimated with a constraint applied such that a significant reversal of revenue in the future is not probable. Revenue is reported in Commissions income on the Consolidated Statement of Total Comprehensive Income. the Company's right Contract assets represent to future consideration for services it has already transferred to the customer, which is subject to certain contingencies. Once the right to consideration becomes unconditional, it is reported as a receivable. Contract assets are evaluated for credit loss under CECL. Management utilizes a PD/LGD approach, similar to the financial guarantee premium one described above receivables and the Company's obligation to transfer services for which it has already received consideration from the customer. Contract assets and receivables are reported as other assets, and contract liabilities are reported as other liabilities, on the Consolidated Balance Sheet. for loans. Contract liabilities represent The Company’s costs to obtain customer contracts relate to certain commissions paid to independent agents for procuring policies. As these costs relate to the Company’s policy placement performance obligation to its customers, they are expensed as incurred. These costs are reported in Commission expenses of Total Comprehensive Income. the Consolidated Statement on Consolidated VIE Refer to Note 11. Variable Interest Entities for further discussion on Ambac's involvement with VIEs and triggering events resulting in consolidation. Ambac consolidated a VIE on December 31, 2023 which has a contract with a governmental to provide construction and facilities management entity services in return for periodic concession payments. These services have been the VIE's performance obligations. Revenue is apportioned to these performance obligations based on their respective stand-alone selling prices. Revenue is estimated based on regularly updated cash flow projections. identified as This is a long-term contract that contains a significant financing component related to construction. As the construction services have already been completed, revenue recognized for this performance obligation will solely consist of interest income. Facilities management services are provided, and thus recognized, over time and will consist of services revenue. Costs to fulfill the customer contract primarily relate to fees paid to vendors to provide the facilities management services and will be expensed as incurred. All revenue and expense items will be reported within Income (loss) from variable interest entities. Contract assets are evaluated for credit losses under CECL. Management utilizes a PD/LGD approach, similar to the one described above for financial guarantee premium receivables and loans. Contract assets are reported within Derivative and other assets in the Variable interest entity asset section of the Consolidated Balance Sheet.

AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) Employee Benefits Postretirement and Postemployment Benefits Ambac provides postretirement and postemployment benefits, including health and life benefits covering employees who meet certain age and service requirements. Ambac accounts for these benefits under the accrual method of accounting. Amounts related to the postretirement health benefits liability are established and charged to expense based on actuarial determinations. Incentive Compensation Incentive compensation is a key component of our compensation strategy. Incentive compensation has two components: short term incentive compensation (consisting of an annual cash bonus) and long term incentive plan awards (consisting of deferred cash and awards of restricted and performance stock units). Annual decisions with regard to incentive compensation are generally made in the first quarter of each year and are based on the prior year's performance for the Company, the employee and the employee's business unit. In 2020, the Ambac 2013 Incentive Compensation Plan (the “2013 Incentive Plan”) was superseded by the 2020 Incentive Compensation Plan ("2020 Incentive Plan"). Both plans allow for the granting of stock options, restricted stock, stock appreciation rights, restricted and performance units and other awards to employees, directors and consultants that are valued or determined by reference to Ambac's common stock. Under these plans, Ambac has issued both cash and equity awards to US employees and consultants. In connection with the adoption of the 2020 Incentive Plan, all shares reserved but unissued under the 2013 Incentive Plan were transferred to the the 2020 Incentive Plan in addition to any shares underlying outstanding awards under the 2013 Incentive Plan as of June 2, 2020 that subsequently terminate by expiration or forfeiture, cancellation, or otherwise are not issued. Under the 2013 and 2020 Incentive Compensation Plans. Ambac recognizes compensation costs for all equity classified awards granted at fair value, which is measured on the grant date, and records forfeitures for unvested shares only when they occur. For awards include service and performance conditions, the fair value is the market price of Ambac stock on the grant date. For awards that also contain a market condition, specifically a total shareholder return ("TSR") modifier, the fair value is estimated using a Monte Carlo simulation. that only The types of equity awards granted to employees are as follows: • Restricted stock units — only require future service and accordingly the respective fair value is recognized as compensation expense over the relevant service period. the achievement of group. Compensation costs for all performance stock units are only recognized when the performance conditions are considered probable. Once deemed probable, such compensation costs are recognized as compensation expense over the relevant service period. Compensation costs are initially based on the probable outcome of the performance conditions and adjusted for subsequent changes in the estimated or actual outcome each reporting period as necessary. Changes in the estimated or actual outcome of a performance condition are recognized by reflecting a retrospective adjustment to compensation cost in the current period. In 2020, the Ambac UK Board of Directors adopted a long term incentive plan for Ambac UK employees, which includes both performance and time based awards. Compensation costs for all performance based awards are based on the probable outcome of the performance conditions and adjusted for subsequent changes in the estimated or actual outcome each reporting period as necessary. Compensation costs for time-based awards are recognized evenly over the service period. Operating Leases A contract contains a lease if it conveys the right to control the use of identified property, plant, or equipment for a period of time in exchange for consideration. Ambac's evaluation of whether certain contracts contain leases requires judgment regarding what party controls the asset and whether the asset is physically distinct. Ambac is the lessee in leases which are classified as operating leases. Ambac recognizes a single lease cost, calculated so that the cost is allocated generally on a straight-line basis over the lease term within operating expenses in the Consolidated Statements of Total Comprehensive Income (Loss). The lease term commences on the earlier of the date when we become legally obligated for the rent payments or the date on which we take possession of the property. For such operating leases, Ambac recognizes a right-of-use ("ROU") asset and a lease liability, initially measured at the present value of the lease payments. The discount rate used to initially measure the ROU assets and lease liabilities reflects the estimated secured borrowing rate of the applicable Ambac subsidiary, which considers the rate of existing or recent debt obligations of the entity. All cash payments are classified within operating activities in the statement of cash flows. For contracts where Ambac is the lessee, we have elected the short-term lease recognition exemption for all leases that qualify. For those leases that qualify for that exemption, we will not recognize ROU assets or lease liabilities. For all contracts where Ambac is the lessee and lessor we have also elected the lease and non-lease to not separate practical expedient components. specified performance • Performance stock units — require both future service and achieving to vest. Performance stock unit grants also include a market condition TSR modifier that will cause the total payout at the end the performance period to increase or decrease depending on Ambac's stock performance relative to a peer targets Ambac Financial Group, Inc 79 2023 Form 10-K AMBAC FINANCIAL GROUP, INC.

Ambac and its subsidiaries also file separate or combined income tax returns in various states, local and foreign jurisdictions. Current tax assets and liabilities are recognized for taxes refundable or payable for the current year. to differences between Deferred tax assets and liabilities are recognized for the future tax consequences attributable the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on current and deferred tax assets and liabilities of a change in tax rates is recognized in the period that includes the enactment date. The Income Taxes Topic of the ASC requires that companies assess whether valuation allowances should be established against their deferred tax assets based on management's assessment and consideration of all available evidence using a ‘more likely than not' standard. In making such judgments, significant weight is given to evidence that can be objectively verified. The level of deferred tax asset recognition is influenced by management’s assessment of future profitability, which depends on the existence of sufficient taxable income within the carry forward periods available under the tax law. Net Income Per Share Basic net income per share is computed by dividing net income attributable to common stockholders, including the adjustment to redemption value of the redeemable noncontrolling interest, by the weighted-average number of common shares outstanding and vested restricted stock units (together, "Basic Weighted Average Shares Outstanding"). Diluted net income per share is computed by dividing net income attributable to common stockholders, including the adjustment to redemption value of the redeemable controlling interest, by the Basic Weighted- Average Shares Outstanding plus all potentially dilutive common shares outstanding during the period. All potentially dilutive common shares outstanding consider common stock deliverable pursuant to warrants, unvested restricted stock units and performance existing compensation plans. stock units granted under Depreciation of furniture and fixtures, certain information technology development costs and electronic data processing equipment is charged over the estimated useful lives of the respective assets, ranging from three to five years, using the straight-line method. Amortization of leasehold improvements is charged over the remaining term of the respective operating lease using the straight-line method. Foreign Currency Financial statement accounts expressed in foreign currencies are translated into U.S. dollars in accordance with the Foreign Currency Matters Topic of the ASC. The functional currencies of Ambac's subsidiaries are the local currencies of the country where the respective subsidiaries are based, which are also the primary operating environments in which the subsidiaries operate. Income Foreign currency translation: Functional currency assets and liabilities of Ambac’s foreign subsidiaries are translated into U.S. dollars using exchange rates in effect at the balance sheet dates and the related translation adjustments, net of deferred taxes, are included as a component of Accumulated Other in Stockholders' Equity. (Loss) Comprehensive Functional currency operating results of foreign subsidiaries are translated using average exchange rates. Foreign currency transactions: The impact of non- functional currency transactions and the remeasurement of non- functional currency assets and liabilities into the respective subsidiaries' functional currency (collectively "foreign currency transactions gains/(losses)") are $(3), $11 and $(7) for the years ended December 31, 2023, 2022 and 2021, respectively. Foreign currency transactions gains/(losses) are primarily the result of remeasuring Ambac UK's assets and liabilities denominated in currencies (primarily the U.S. dollar and the Euro) other than its functional currency (the British Pound Sterling). Commitments and Contingencies The Company and its subsidiaries are defendants in or parties to actual, pending and threatened lawsuits and proceedings. A liability is accrued for such contingencies when a loss is both probable and reasonably estimable. If a loss is not "probable and reasonably estimable," but is reasonably possible, disclosure of the contingency and an estimate of the loss or range of loss is required if such an estimate can be determined. Significant management judgment is required to apply this guidance. As a legal contingency develops, the Company, in conjunction with outside counsel, evaluates what level of accrual and/or disclosure is required under the guidance.

Future Application of Accounting Standards Segment Reporting: In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) - Improvement to Reportable Segment Disclosures. The ASU requires disclosure of the following: • Significant segment expenses regularly provided to the chief operating decision maker (CODM) and included within the reported measure(s) of a segment’s profit or loss. • The amount and composition of "other segment items". This amount reconciles segment revenue, less significant expenses, to the reported measure(s) of a segment’s profit or loss. • The CODM's title and position. • How the CODM uses the reported measure(s) of a segment’s profit or loss to assess segment performance and decide how to allocate resources. • All segment profit or loss and assets disclosures currently required annually by Topic 280, as well as those introduced by the ASU, to also be disclosed in interim periods. The ASU also permits a public entity to report multiple measures of a segment’s profit or loss as long as: i) all the reported measures of a segment’s profit or loss are used by the CODM for purposes of assessing performance and allocating resources; and ii) the measure closest to GAAP is also provided. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. Ambac will adopt this ASU for the annual reporting period ending December 31, 2024 and we are evaluating its impact on Ambac's financial statements. Income Taxes: In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) - Improvements to Income Tax Disclosures. The enhancements in the ASU include the following: • Within the rate reconciliation table, disclosure of additional categories of information about federal, state and foreign income taxes and providing more details about the reconciling items in some categories if the items meet a quantitative threshold. • Annual disclosure of income taxes paid (net of refunds received) disaggregated by federal (national), state and foreign taxes and disaggregation of the information by jurisdiction based on a quantitative threshold. • Other disclosures include: i) income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and ii) income tax expense (or benefit) from continuing operations disaggregated by federal (national), state, and foreign. The ASU is effective for annual periods beginning after December 15, 2024, with early adoption permitted.

Management's evaluation as of December 31, 2023, includes the expectation that all principal and interest payments on securities guaranteed by AAC or Ambac UK will be made timely and in full. Ambac’s assessment about whether a security is credit impaired reflects management’s current judgment regarding facts and circumstances specific to the security and other factors. If that judgment changes, Ambac may record a charge for credit impairment in future periods. The declines in fair value and resultant unrealized losses across asset classes as of December 31, 2023, included in the above table resulted from the impact of increasing interest rates and market spreads. Management has determined that the securities with unrealized impaired. Further losses are not credit discussion of management's assessment with respect to security categories with larger unrealized loss balances is below. Corporate obligations The gross unrealized losses on corporate obligations as of December 31, 2023, resulted from an increase in interest rates and, to a lesser extent, market spreads since the securities were purchased. Unrealized losses of $44 related to 662 investment grade securities with an average unrealized loss equal to 7% of amortized cost at December 31, 2023. Securities that have below investment grade credit ratings or are unrated comprise $1 of the gross unrealized loss and have an average unrealized loss equal to 5% of amortized cost at December 31, 2023. Management believes that the full and timely receipt of all principal and interest payment on corporate obligations with unrealized losses as of December 31, 2023, is probable. Residential mortgage-backed securities As of December 31, 2023, all of the $14 unrealized loss on residential mortgage-backed securities related to 11 Ambac- insured securities. Four of these account for $13 of the unrealized loss and have an average unrealized loss equal to 14% of amortized cost. The majority of these unrealized losses relate to securities with long dated weighted average lives making their fair values more sensitive to interest rate changes. Also, most of these securities have below investment grade credit ratings or are unrated. The unrealized losses on these obligations resulted from adverse market conditions for long dated credit assets. As noted above, expected cash flows used in evaluating credit impairment of Ambac-insured securities contemplate full and timely payment of all principal and interest payments on Ambac-insured securities. This assumption is included in the projection of model based cash flows used in evaluating credit in securitized financial assets, including the residential mortgage backed and student loan asset backed securities included in this group. impairments on beneficial interests Investment Income (Loss) Net investment income (loss) was comprised of the following for the affected periods: Year Ended December 31, 2023 2022 2021 Fixed maturity securities $ Short-term investments Loans Investment expense Securities available-for-sale and short-term Fixed maturity securities - trading Other investments $ 76 22 — (6) 93 7 40 $ 61 11 1 (6) 66 (23) (26) 78 — — (6) 74 — 66 Total net investment income (loss) $ 140 $ 17 $ 139 Net investment income (loss) from Other investments primarily represents changes in fair value on equity securities including certain pooled investment funds, and income from investment limited partnerships and other equity interests accounted for under the equity method.

The increase of $3 for the year ended December 31, 2023 relates to additions to the allowance for credit losses on residential mortgage-backed securities for which credit losses were not previously recorded. Ambac did not purchase any financial assets with credit deterioration for the years ended December 31, 2023 and 2022. Counterparty Collateral, Deposits with Regulators and Other Restrictions Ambac routinely pledges and receives collateral related to certain transactions. Securities held directly in Ambac’s investment portfolio with a fair value of $27 and $64 at December 31, 2023 and 2022, respectively, were pledged to derivative counterparties. Ambac’s derivative counterparties have the right to re-pledge the investment securities and as such, these pledged securities are separately classified on the investments Consolidated Balance Sheets as "Short-term Other Investments pledged as collateral, at fair value". Refer to Note 9. Derivative Instruments for further information on cash collateral. There was no cash or securities received from other counterparties that were re-pledged by Ambac. Securities carried at $24 and $23 at December 31, 2023 and 2022, respectively, were deposited by Ambac's insurance subsidiaries with governmental authorities or designated custodian banks as required by laws affecting insurance companies. Invested assets carried at $1 as December 31, 2023, were deposited as security in connection with a letter of credit issued for an office lease. Fiduciary funds held by Ambac's insurance distribution subsidiaries, carried at $2 and $0 at December 31, 2023 and 2022, respectively, are included in invested assets. Guaranteed Securities Ambac’s fixed maturity portfolio includes securities covered by guarantees issued by AAC or Ambac UK (“insured securities”).

There were no impairments recorded on these investments or adjustments to fair value to reflect observable price changes in identical or similar investments from the same issuer during the periods presented. The portion of net unrealized gains (losses) related to securities classified as trading and equity securities, excluding those reported using the equity method, still held at the end of each period is as follows: Year Ended December 31, 2023 2022 2021 Net gains (losses) recognized during the period on trading and equity securities Less: net gains (losses) recognized during the reporting period on trading and equity securities sold during the period Unrealized gains (losses) recognized during the reporting period on trading and equity securities still held at the reporting date $ 25 $ (48) $ 23 18 (26) 1 $ 7 $ (22) $ 22 The Fair Value Measurement Topic of the ASC establishes a framework for measuring fair value and disclosures about fair value measurements. Fair Value Hierarchy The Fair Value Measurement Topic of the ASC specifies a fair value hierarchy based on whether the inputs to valuation techniques used to measure fair value are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect Company-based assumptions. The fair value hierarchy has three broad levels as follows: l Level 1 Quoted prices for identical instruments in active markets. Assets and liabilities classified as Level 1 include US Treasury and other foreign government obligations traded in highly liquid and transparent markets, certain highly liquid pooled fund investments, exchange traded futures contracts and money market funds. l Level 2 l Level 3 Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. Assets and liabilities classified as Level 2 generally include investments in fixed maturity securities representing municipal, asset-backed and corporate obligations, certain interest rate swap contracts and most long-term debt of variable interest entities consolidated under the Consolidation Topic of the ASC. Model derived valuations in which one or more significant inputs or significant value drivers are unobservable. This hierarchy requires the use of observable market data when available. Assets and liabilities classified as Level 3 include certain uncollateralized interest rate swap contracts and certain investments in fixed maturity securities. Additionally, Level 3 assets and liabilities generally include loan receivables, and certain long-term debt of variable interest entities consolidated under the Consolidation Topic of the ASC. The Fair Value Measurement Topic of the ASC permits, as a practical expedient, the estimation of fair value of certain investments in funds using the net asset value per share of the investment or its equivalent (“NAV”). Investments in funds valued using NAV are not categorized as Level 1, 2 or 3 under the fair value hierarchy. The Investments — Equity Securities Topic of the ASC permits the measurement of certain equity securities without a readily determinable fair value at cost, less impairment, and adjusted to fair value when observable price changes in identical or similar investments from the same issuer occur (the "measurement alternative"). The fair values of investments measured under this measurement alternative are not included in the below disclosures of fair value of financial instruments.

Determination of Fair Value When available, Ambac uses quoted active market prices specific to the financial instrument to determine fair value and classifies such items within Level 1. The determination of fair value for financial instruments categorized in Level 2 or 3 involves judgment due to the complexity of factors contributing to the valuation. Third-party sources from which we obtain independent market quotes also use assumptions, judgments and instrument values and estimates in determining financial Ambac Financial Group, Inc 88 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) different third parties may use different methodologies or provide different values for financial instruments. In addition, the use of internal valuation models may require assumptions about hypothetical or inactive markets. As a result of these factors, the actual trade value of a financial instrument in the market, or exit value of a financial instrument position by Ambac, may be significantly different from its recorded fair value. Ambac’s financial instruments carried at fair value are mainly comprised of investments in fixed maturity securities, equity interests in pooled investment funds, derivative instruments, and certain variable interest entity assets and liabilities. Valuation of financial instruments is performed by Ambac’s finance group using methods approved by senior financial management with consultation from risk management and portfolio managers as appropriate. Preliminary valuation results are discussed with portfolio managers quarterly to assess consistency with market transactions and trends as applicable. Market transactions such as trades or negotiated settlements of similar positions, if any, are reviewed to validate fair value model results. However many of significant unobservable inputs have very little or no observable market activity. Methods and significant inputs and assumptions used to determine fair values across portfolios are reviewed quarterly by senior control financial management. Other valuation procedures specific to particular portfolios are described further below. instruments valued using financial the Fixed Maturity Securities The fair values of fixed maturity investment securities are based primarily on market prices received from broker quotes or alternative pricing sources. Because many fixed maturity securities do not trade on a daily basis, pricing sources apply available market information through processes such as matrix pricing to calculate fair value. Such prices generally consider a variety of factors, including recent trades of the same and similar securities. In those cases, the items are classified within Level 2. For those fixed maturity investments where quotes were not available or cannot be reasonably corroborated, fair values are based on internal valuation models. Key inputs to the internal valuation models generally include maturity date, coupon and yield curves for asset-type and credit rating characteristics that closely match those characteristics of the specific investment securities being valued. Items valued using valuation models are classified according to the lowest level input or value driver that is significant to the valuation. Thus, an item may be classified in Level 3 even though there may be significant inputs that are readily observable. Longer (shorter) expected maturities or higher (lower) yields used in the valuation model will, in isolation, result in decreases (increases) in fair value. Generally, lower credit ratings or longer expected maturities will be accompanied by higher yields used to value a security. At December 31, 2023, approximately 2%, 94%, and 4% of the fixed maturity investment portfolio (excluding variable interest entity investments) was valued using broker internal valuation quotes, alternative pricing sources and models, respectively. At December 31, 2022, approximately 5%, 91%, and 4% of the fixed maturity investment portfolio (excluding variable interest entity investments) was valued using broker quotes, alternative pricing sources and internal valuation models, respectively. Ambac performs various review and validation procedures to quoted and modeled prices for fixed maturity securities, including price variance analyses, missing and static price reviews, overall valuation analysis by portfolio managers and finance managers and reviews associated with our ongoing impairment analysis. Unusual prices identified through these procedures will be evaluated further against alternative third- party quotes (if available), internally modeled prices and/or other relevant data, and the pricing source values will be challenged as necessary. Price challenges generally result in the use of the pricing source’s quote as originally provided or as revised by the source following their internal diligence process. A price challenge may result in a determination by either the pricing source or Ambac management that the pricing source cannot provide a reasonable value for a security or cannot adequately support a quote, in which case Ambac would resort to using either other quotes or internal models. Results of price challenges are reviewed by portfolio managers and finance managers. Information about the valuation inputs for fixed maturity securities classified as Level 3 is included below: Other asset-backed securities: This security is a subordinated tranche of a securitization collateralized by Ambac-insured military housing bonds. The fair value classified as Level 3 was $68 and $67 at December 31, 2023 and 2022, respectively. Fair value was calculated using a discounted cash flow approach with expected future cash flows discounted using a yield consistent with the security type and rating. Significant inputs for the valuation at December 31, 2023 and 2022 include the following: December 31, a. Coupon rate .............................................. 2023 5.97% 2022 5.98% b. Average Life ............................................ 12.80 years 13.46 years c. Yield ......................................................... 12.00% 12.60% Corporate obligations: This includes certain investments in convertible debt securities. The fair value classified as Level 3 was $19 and $12 at December 31, 2023 and 2022, respectively. Fair value was calculated by discounting cash flows to average maturity of 0.89 years and yield of 11.2% at December 31, 2023, and 1.75 years and a yield of 11.3% at December 31, 2022. Yields used are consistent with the security type and rating. Other Investments Other investments primarily relate to investments in pooled investment funds. The fair value of pooled investment funds is determined using dealer quotes or alternative pricing sources when such investments have readily determinable fair values. When fair value is not readily determinable, pooled investment funds are valued using NAV as a practical expedient as permitted under the Fair Value Measurement Topic of the ASC. Refer to Note 4. Investments for additional information about such investments in pooled funds that are reported at fair value using NAV as a practical expedient. Ambac Financial Group, Inc 89 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) Derivative Instruments Ambac’s derivative instruments primarily comprise interest rate swaps and exchange traded futures contracts. Fair value is determined based upon market quotes from independent sources, when available. When independent quotes are not available, fair value is determined using valuation models. These valuation models require market-driven inputs, including contractual terms, credit spreads and yield curves. The valuation of certain derivative contracts also require the use of data inputs and assumptions that are determined by management and are not readily observable in the market. Under the Fair Value Measurement Topic of the ASC, Ambac is required to consider its own credit risk when measuring the fair value of derivative liabilities. Factors considered in estimating the amount of any Ambac credit valuation adjustment ("CVA") on such contracts include collateral posting provisions, right of set-off with the counterparty, the period of time remaining on the derivative and the pricing of recent terminations. The aggregate Ambac CVA impact was not significant to the fair value of derivatives at both December 31, 2023 or 2022. Interest rate swaps that are not centrally cleared are valued using vendor-developed models that incorporate interest rates and yield curves that are observable and regularly quoted. These models provide the net present value of the derivatives based on contractual terms and observable market data. Generally, the need for counterparty (or Ambac) CVAs on interest rate derivatives is mitigated by the existence of collateral posting agreements under which adequate collateral has been posted. Certain of these derivative contracts entered into with financial guarantee customers are not subject to collateral posting agreements. Counterparty credit risk related to such customer derivative assets is included in our determination of their fair value. As of December 31, 2023 Ambac holds warrants to purchase preferred stock of a development stage company. These warrants have a fair value of $1 as of December 31, 2023, determined using a standard warrant valuation model with internally developed input assumptions. Financial Guarantees Fair value of net financial guarantees written represents our estimate of the cost to Ambac to completely transfer its insurance obligation to another market participant of comparable credit worthiness. In theory, this amount should be the same amount that another market participant of comparable credit worthiness would hypothetically charge in the marketplace, on a present value basis, to provide the same protection as of the balance sheet date. This fair value estimate of financial guarantees is presented on a net basis and includes direct and assumed contracts written, net of ceded reinsurance contracts. Long-term Debt As of December 31, 2023, long-term debt includes AAC surplus notes and the Ambac UK debt issued in connection with a policy commutation. As further described in Note 12. Long-term Debt the Tier 2 Notes were fully redeemed effective January 15, 2023. The fair values of surplus notes and Tier 2 Notes are classified as Level 2. The fair value of Ambac UK debt is classified as Level 3. Other Financial Assets and Liabilities Included in Other assets are loans, the fair values of which are estimated based upon internal valuation models and are classified as Level 3. Variable Interest Entity Assets and Liabilities liabilities of Legacy Financial The financial assets and Guarantee Insurance VIEs ("LFG VIEs") consolidated under the Consolidation Topic of the ASC consist primarily of fixed maturity securities and loans held by the VIEs, derivative instruments and notes issued by the VIEs which are reported as long-term debt. As described in Note 11. Variable Interest Entities, these LFG VIEs are securitization entities which have liabilities and/or assets guaranteed by AAC or Ambac UK. The fair values of LFG VIE long-term debt are based on price quotes received from independent market sources when available. Such quotes are considered Level 2 and generally consider a variety of factors, including recent trades of the same and similar securities. For those instruments where quotes were not available or cannot be reasonably corroborated, fair values are based on internal valuation models and classified Level 3. Comparable to the sensitivities of investments in fixed maturity securities described above, longer (shorter) expected maturities or higher (lower) yields used in the valuation model will, in isolation, result in decreases (increases) in fair value liability measurement for LFG VIE long-term debt. LFG VIE derivative asset and liability fair values are determined using vendor-developed valuation models, which incorporated observable market data related to specific derivative contractual terms including interest rates, foreign exchange rates and yield curves. The fair value of LFG VIE fixed maturity securities and loan assets are generally based on Level 2 market price quotes received from independent market sources when available. When LFG VIE asset fair values are not readily available from market quotes, values are estimated internally and classified Level 3. Internal valuations of LFG VIE’s fixed maturity securities or loan assets are derived from the fair values of the notes issued by the respective VIE and the VIE’s derivatives, determined as described above, adjusted for the fair values of Ambac’s financial guarantees associated with the VIE. The fair value of financial guarantees consist of: (i) estimated future premium cash flows discounted at a rate consistent with that implicit in the fair value of the VIE’s liabilities and (ii) estimates of future claim payments discounted at a rate that includes Ambac’s own credit risk. Estimated future premium payments to be paid by the VIEs were discounted at a weighted average rate of 6.3% and 6.8% at December 31, 2023 and 2022, respectively. At December 31, 2023, the range of these discount rates was between 5.3% and 7.8%. At December 31, 2022, the range of these discount rates was between 5.8% and 8.5%.

AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) Additional Fair Value Information for Financial Assets and Liabilities Accounted for at Fair Value The following tables present the changes in the Level 3 fair value category for the periods presented in 2023, 2022 and 2021. Ambac classifies financial instruments in Level 3 of the fair value hierarchy when there is reliance on at least one significant unobservable input to the valuation model. In addition to these unobservable inputs, the valuation models for Level 3 financial instruments typically also rely on a number of inputs that are readily observable either directly or indirectly. Thus, the gains and losses presented below include changes in the fair value related to both observable and unobservable inputs.

Claim files are generally created at the claimant by coverage type, depending on the particular facts and circumstances of the underlying event. For purposes of the claims development tables above, claims reported for direct business are counted even if they eventually close with no loss payment. Note that claims with zero claim dollars may still generate some level of claim adjustment expenses. Claim counts for assumed business are included only to the extent such counts are available. The methods used to summarize claim counts have not changed significantly over the time periods reported in the tables above. The Company cautions against using the summarized claim count information provided in this disclosure in attempting to project ultimate loss payouts by product line. The Company generally finds claim count data to be useful only on a more granular basis than the aggregated basis disclosed in the claim development tables above, as the risks, average values and other Ambac Financial Group, Inc 98 2023 Form 10-K AMBAC FINANCIAL GROUP, INC.

Reinsurance Recoverables, Including Credit Impairments: Ambac’s reinsurance assets, including deferred ceded premiums and reinsurance recoverables on losses amounted to $398 at December 31, 2023. Credit exposure existed at December 31, 2023, with respect to reinsurance recoverables to the extent that any reinsurer may not be able to reimburse Ambac under the terms of these reinsurance arrangements. At December 31, 2023, there were ceded reinsurance balances payable of $90 offsetting this credit exposure. Contractually ceded reinsurance payables can only be offset against amounts owed from the same reinsurer in the event that such reinsurer is unable to meet its obligations to reimburse Ambac. To minimize its credit exposure to losses from reinsurer insolvencies, Ambac (i) is entitled to receive collateral from its reinsurance counterparties in certain reinsurance contracts and (ii) has certain cancellation rights that can be exercised by Ambac in the event of rating agency downgrades of a reinsurer (among other events and circumstances). Ambac held letters of credit and collateral amounting to $131 from its reinsurers at December 31, 2023. For those reinsurance counterparties that do not currently post collateral, Ambac's reinsurers are well capitalized, highly rated, authorized capacity providers. Additionally, while legacy liabilities from the Providence Washington Insurance Company ("PWIC") acquisition and the three admitted carriers acquired by Everspan on January 3, 2022 (the "21st Century Companies") were fully ceded to certain reinsurers, Everspan also benefits from an unlimited, uncapped indemnity from Enstar Holdings (US) and 21st Century Premier Insurance Company, respectively, to mitigate any residual risk to these reinsurers. For 2023, our top three reinsurers represented 74% our total reinsurance recoverables on paid and unpaid losses. These reinsurance recoverables were primarily from reinsurers with applicable ratings of A or better. The following table sets forth our three most significant reinsurers by amount of reinsurance recoverable as of December 31, 2023.

(3) Reinsurance recoverables reduced by ceded premiums payables due to reinsurers, letters of credit, and collateral posted for the benefit of Ambac. Ambac has uncollateralized credit exposure to reinsurers of $128 and $60 and has recorded an allowance for credit losses of less than a million at December 31, 2023 and December 31, 2022, respectively. The uncollateralized credit exposure to reinsurers the acquisitions of PWIC and the 21st Century Companies of $44 and $45 at December 31, 2023 and December 31, 2022, respectively.

INSURANCE REGULATORY RESTRICTIONS United States AAC is domiciled in the State of Wisconsin and, as such, it is subject to the insurance laws and regulations of the State of Wisconsin (the “Wisconsin Insurance Laws”) and is regulated by the OCI as a domestic insurer. Everspan Indemnity and its wholly owned subsidiary, Everspan Insurance Company ("Everspan Insurance"), are domiciled in Arizona and are subject to the insurance laws and regulations of Arizona (the “Arizona Insurance Laws”) and are regulated by the Arizona Department of Insurance and Financial Institutions as domestic insurers. The other subsidiaries of Everspan Insurance (Providence Washington Insurance Company, Greenwood Insurance Company, Consolidated National Insurance Company and Consolidated Specialty Insurance Company; together with Everspan Insurance, the "Everspan Admitted Carriers") are domiciled in various States and are therefore subject to the insurance laws and regulations of their respective States of domicile (together with the Wisconsin Insurance Laws and the Arizona Insurance Laws, the “State Insurance Laws”) and regulated by the insurance departments of those States as domestic insurers. In addition, AAC and the Everspan Admitted Carriers are subject to the insurance laws and regulations of the other jurisdictions in which they are licensed and operate as foreign insurers. Insurance laws and regulations applicable to insurers vary by jurisdiction, but the insurance laws and regulations applicable to our insurance carriers generally require them to maintain minimum standards of business conduct and solvency; to meet certain financial tests; and to file policy forms, premium rate schedules and certain reports with regulatory authorities, including information concerning capital structure, ownership, financial condition (such as risk-based capital), corporate governance and enterprise risk. AAC, because it is a financial risk-based capital guarantee requirements. As a run-off financial guarantor, AAC has been operating under the Stipulation and Order required by OCI. OCI has developed and implemented OCI's Runoff Capital Framework to assist OCI with decision making related to capital and liquidity management at AAC. OCI cannot require AFG or any other Ambac entity to contribute capital to or otherwise support AAC. See Note 1.

The State Insurance Laws also require prior approval (or non-disapproval) of certain transactions between an insurance carrier and its affiliates. The level of supervisory authority that may be exercised by non- domiciliary jurisdiction. Generally, however, non-domiciliary regulators are authorized to suspend or revoke the insurance license they issued and to impose restrictions on that license in the event that laws or regulations are breached by a regulated insurance company or in the event that continued or unrestricted licensing of the regulated insurance company constitutes a “hazardous condition” (or meets a similar standard) in the opinion of the non-domiciliary regulator. regulators varies by The domiciliary regulators have primary regulatory authority, including with respect to the initiation and administration of rehabilitation or liquidation proceedings. Additionally, the accounts and operations of AAC, Everspan Indemnity and the Everspan Admitted Carriers are subject to individual periodic comprehensive their domestic financial examinations by regulators, and may be examined collectively by the lead regulator of the affiliated insurance company group. In December 2020, Everspan Insurance completed its re- domestication from Wisconsin to Arizona and obtained broad authority to write property and casualty insurance (while contemporaneously surrendering its authority to write financial guaranty insurance) in Arizona. Everspan Insurance thereafter sought similar amendments to its certificates of authority in all other states. Everspan Indemnity and the Everspan Admitted Carriers (collectively, "Everspan") are subject to risk-based capital requirements. Everspan Indemnity was formed in 2020 as a domestic surplus lines insurer in Arizona and, accordingly, is eligible to write property and casualty insurance as an excess and surplus lines insurance in all states by virtue of the U.S. Nonadmitted and Reinsurance Reform Act of 2010. All of Ambac's insurance subsidiaries are in compliance with the minimum capital and surplus levels required under the State Insurance Laws required to transact all business written to date. general Insurance Distribution businesses, like some other Our managing program administrators, may be subject to licensing requirements and regulation by insurance regulators in various states in which they conduct business. brokerages agents, and In addition to the legal restrictions applicable to AAC as described herein, pursuant to the terms of the Settlement Agreement and the Stipulation and Order, AAC must seek prior approval by OCI of certain corporate actions. The Settlement Agreement and Stipulation and Order include covenants which restrict the operations of AAC. The Settlement Agreement will remain in force until the surplus notes that were issued pursuant to the Settlement Agreement have been redeemed, repurchased or repaid in full. The Stipulation and Order will remain in force for so long as OCI determines it to be necessary. Certain of the restrictions in the Settlement Agreement may be waived with the approval of the OCI and/or the requisite percentage of holders of AAC's surplus notes. See Note 1. Background and Business Description for additional information. Although not domiciled in New York, AAC is nevertheless subject to the New York insurance law governing financial guarantee insurers. New York’s comprehensive financial guarantee insurance law defines the scope of permitted financial guarantee insurance and governs the conduct of business of all financial guarantors licensed to do business in New York, including AAC. The New York financial guarantee insurance law also establishes single and aggregate risk limits with respect to insured obligations insured by financial guarantee insurers. Such single risk limits are specific to the type of insured obligation (for example, municipal or asset-backed). Under the aggregate limits, policyholders’ surplus and contingency reserves must at least equal a percentage of aggregate net liability that is equal to the sum of various percentages of aggregate net liability for various categories of specified obligations. At December 31, 2023, AAC is in compliance with applicable aggregate risk limits and applicable single risk limits. The financial statements of AAC and Everspan are prepared on the basis of accounting practices prescribed or permitted by the State Insurance Laws and the actions of regulatory authorities thereunder. AAC and Everspan use such statutory accounting practices prescribed or permitted by the applicable regulatory their financial authorities for determining and reporting condition and results of operations, including for determining solvency under the State Insurance Laws. The States in which AAC and Everspan are domiciled have adopted the National Association of Insurance Commissioners (“NAIC”) accounting practices and procedures manual (“NAIC SAP”) as a component of prescribed practices as codified in each State’s applicable law or regulation. Statutory policyholder surplus differs from stockholder's equity determined under GAAP principally due to statutory accounting rules that treat financial guarantee premiums and loss reserves, investments, net acquisition costs, consolidation of subsidiaries or variable interest entities and surplus notes differently. The following are details of statutory surplus for AAC and Everspan Indemnity: • AAC’s statutory policyholder surplus was $897 at December 31, 2023, as compared to $598 as of December 31, 2022. • Everspan Indemnity has statutory policyholder surplus of $108 as of December 31, 2023 as compared to $107 as of December 31, 2022. Everspan does not have permitted or additional prescribed practices at December 31, 2023 or December 31, 2022. The OCI has prescribed additional practices and has permitted accounting practices for AAC. As a result of the prescribed and permitted practices discussed below, AAC’s statutory surplus at December 31, 2023 and 2022 was lower by $24 and higher by Ambac Financial Group, Inc 100 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) $90, respectively, than if AAC had reported such amounts in accordance with NAIC SAP. investments be reported at amortized cost regardless of its NAIC risk designation. Additional Prescribed Accounting Practices AAC: Permitted Accounting Practices AAC: OCI has prescribed the following accounting practices that differ from NAIC SAP for AAC: OCI has allowed the following permitted practice for AAC: • Paragraph 8 of Statement of Statutory Accounting Principles No. 60 “Financial Guaranty Insurance” allows for a deduction from loss reserves for the time value of money by application of a discount rate equal to the average rate of return on the admitted assets of the financial guaranty insurer as of the date of the computation of the reserve. The discount rate shall be adjusted at the end of each calendar year. Additionally, in accordance with paragraph 13.e of Statutory Accounting Principles No. 97 "Investments in Subsidiary, Controlled and Affiliated Entities" and paragraph 8 of Statutory Accounting Principles No. 5R “Liabilities, Contingencies and Impairments of Assets - Revised”, AAC records probable losses on its subsidiaries for which it guarantees their obligations. AAC also discounts probable losses on guarantees of subsidiary obligations using a discount rate equal to the average rate of return on its admitted assets. AAC’s average rates of return on its admitted assets at December 31, 2023 and 2022 were 5.86% and 3.22%, respectively. OCI has directed AAC to utilize a prescribed discount rate of 5.10% for the purpose of discounting both its loss reserves and its probable losses on subsidiary guarantees. • Paragraph 4 of Statement of Statutory Accounting Principles No. 41 “Surplus Notes” (“SSAP 41”) states that proceeds received by the issuer of surplus notes must be in the form of cash or other admitted assets having readily determinable values and liquidity satisfactory to the commissioner of the state of domicile. Under statutory accounting principles, surplus notes issued in conjunction with commutations or the settlement of obligations would be valued at zero upon issuance pursuant to paragraph 4, SSAP 41. OCI has directed the Company to record surplus notes issued in connection with commutations or the settlement of obligations at full par value upon issuance. The surplus notes issued have a claim against surplus senior to the preferred and common shareholders. • Paragraph 35 of Statement of Statutory Accounting Principles No. 43R ”Loan-backed and Structured Securities” states that when an other-than-temporary impairment ("OTTI") has occurred, the amount of the OTTI recognized as a realized loss shall equal the difference between the investment’s amortized cost basis and the present value of cash flows expected to be collected, discounted at the loan-backed or structured security’s effective interest rate. From June 11, 2014 to February 12, 2018, OCI had directed AAC to not evaluate for OTTI investments in AAC insured securities with designated policies that were allocated to a segregated account of AAC in rehabilitation overseen by OCI, and required all such • Wisconsin accounting practices for changes to contingency reserves differ from NAIC SAP. Under NAIC SAP, contributions to and releases from the contingency reserve are recorded via a direct charge or credit to surplus. Under the Wisconsin Administrative Code, contributions to and releases from the contingency reserve are to be recorded through underwriting income. AAC received permission from OCI to record contributions to and releases from the contingency reserve, in accordance with NAIC SAP. United Kingdom The Prudential Regulatory Authority (“PRA”) and Financial Conduct Authority (“FCA”) (and their predecessor regulator the Financial Services Authority (“FSA”)) are the dual statutory regulator responsible for regulating the financial services industry the purpose of maintaining confidence in the U.K. financial system, providing public understanding of the system, securing the proper degree of protection for consumers and helping to reduce financial crime. the United Kingdom, with in These regulators have exercised significant oversight of Ambac UK since 2008, after Ambac, AAC and Ambac UK began experiencing financial stress. In 2009, Ambac UK’s license to write new business was curtailed by the FSA and the insurance license was limited to undertaking only run-off related activity. As such, Ambac UK is authorized to run-off its credit, suretyship and financial guarantee insurance portfolio in the United Kingdom. The PRA requires that non-life insurance companies such as Ambac UK maintain a margin of solvency at all times in respect of the liabilities of the insurance company, the calculation of which depends on the type and amount of insurance business a company writes. These solvency requirements were amended on January 1, 2016, in order to implement the European Union's "Solvency II" directive on risk-based capital. Ambac UK had previously been in a capital shortfall position as compared to these solvency capital the requirements since December 31, 2021. requirements, but has met Dividend Restrictions, Restrictions United States Including Contractual State Insurance Regulators prescribe rules that determine if AAC and Everspan may declare dividends. In addition, AAC and Everspan are subject to certain restrictions in their respective articles of incorporation with regards to the payment of dividends. Board action authorizing a distribution by an insurance company must generally be reported to the applicable domiciliary regulator prior to payment. In addition, State Insurance Laws generally require regulatory approval for the Ambac Financial Group, Inc 101 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) United Kingdom UK law prohibits Ambac UK 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. Further, the FSA amended Ambac UK’s license in 2010 such that the PRA must specifically approve (“non-objection”) any transfer of value and/ or assets from Ambac UK to AAC or any other Ambac group company, other than in respect of certain disclosed contracts between the two parties (such as in respect of a management services agreement between AAC and Ambac UK). While the UK insurance regulatory laws impose no statutory restrictions on a general insurer’s ability to declare a dividend, the PRA’s and FCA’s rules governing capital extraction by insurance firms in run off require Ambac UK to consider its future capital requirements over a 3 to 5 year period in both base case and downside stress scenarios before declaring a dividend. Ambac UK annually prepares these forecasts and stress tests as part of its regulatory submissions to the PRA each April. If the stress tests and forecasts show adequate liquidity and regulatory capital buffers then, subject to PRA approval, it may be possible for Ambac UK to pay dividends to AAC within the coming twelve month period. payment of extraordinary dividends, which are distributions in amounts that would exceed certain thresholds, such as a percentage of surplus or net income for the prior year or number of years. Everspan does not have sufficient earned surplus at this time to pay ordinary dividends under the State Insurance Laws. Furthermore, certain subsidiaries of Everspan Insurance are restricted from paying dividends to Everspan Insurance until 2025 or later pursuant to the regulatory orders approving the acquisition of those subsidiaries, unless specifically approved by the applicable domiciliary regulator. Due to losses experienced by AAC, AAC has been unable to pay ordinary dividends to AFG since 2008 and will be unable to pay common dividends in 2024 without the prior consent of the OCI, which is extremely unlikely. AAC’s ability to pay dividends is further restricted by the Settlement Agreement (as described below), by the terms of its AMPS (as described below) and by the Stipulation and Order, and decisions by OCI concerning dividends or other releases of capital in respect of AAC's debt and equity will be affected by OCI's Runoff Capital Framework. See Note 1. Background and Business Description for further information. Accordingly, AAC's ability to pay dividends to AFG and the timing thereof remain subject to substantial uncertainty. • Pursuant to the Settlement Agreement, AAC may not make any “Restricted Payment” (which includes dividends from AAC to Ambac) in excess of $5 in the aggregate per annum, other than Restricted Payments from AAC to Ambac in an amount up to $7.5 per annum solely to pay operating expenses of Ambac. Concurrent with making any such Restricted Payment, a pro rata amount of AAC's surplus notes would also need to be redeemed at par. • Under the terms of AAC’s AMPS, dividends may not be paid on the common stock of AAC unless all accrued and unpaid dividends on the AMPS for the then current dividend period have been paid, provided, that dividends on the common stock may be made at all times for the purpose of, and only in such amounts as are necessary for, enabling Ambac (i) to service its indebtedness for borrowed money as such payments become due or (ii) to pay its operating expenses. If dividends are paid on the common stock as provided in the prior sentence, dividends on the AMPS become cumulative until the date that all accumulated and unpaid dividends have been paid on the AMPS. • The Stipulation and Order requires OCI approval for the payment of any dividend or distribution on the common stock of AAC. • OCI's Runoff Capital Framework and decisions based thereon may affect AAC's ability to pay dividends to AFG.

Since June 30, 2023, AFS's only remaining derivative positions include a limited number of legacy customer swaps and their associated hedges. As of December 31, 2023 and 2022, the notional amounts of AFS's derivatives are as follows: Type of Derivative Interest rate swaps—pay-fixed/receive- variable Interest rate swaps—receive-fixed/pay- variable Notional - December 31, 2023 2022 $ 141 $ 167 989 337 Ambac Financial Group, Inc 103 2023 Form 10-K AMBAC FINANCIAL GROUP, INC.

Additionally, given that AAC is no longer rated by an independent rating agency, counterparties have the right to terminate the swap positions. in linked As of December 31, 2023 and 2022, the net liability fair value of derivative to instruments with contingent features Ambac’s own credit risk was $35 and $38, respectively, related to which Ambac had posted cash and securities as collateral with a fair value of $50 and $54, respectively. All such ratings-based contingent features have been triggered requiring maximum collateral levels to be posted by Ambac while preserving counterparties’ rights to terminate the contracts. Assuming all such contracts terminated at fair value on December 31, 2023, settlement of collateral balances and net derivative liabilities would result in a net receipt of cash and/or securities by Ambac. If counterparties elect to exercise their right to terminate, the actual termination payment amounts will be determined in accordance with derivative contract terms, which may result in amounts that differ from market values as reported in Ambac’s financial statements. 10.

VARIABLE INTEREST ENTITIES Ambac, with its subsidiaries, has engaged in transactions with variable interest entities ("VIEs") in various capacities. • AAC and Ambac UK provide financial guarantees for various debt obligations issued by special purpose entities, including VIEs ("LFG VIEs"); • Ambac sponsors special purpose entities that issued notes to investors for various purposes; and • AAC and Ambac UK in collateralized debt invest obligations, mortgage-backed and other asset-backed securities issued by VIEs and their ownership interest is generally insignificant to the VIE and/or they do not have rights that direct the activities that are most significant to such VIE. Ambac Financial Group, Inc 104 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) LFG VIEs AAC and Ambac UK provide financial guarantees in respect of assets held or debt obligations of VIEs. AAC and Ambac UK’s primary variable interest exists through this financial guarantee insurance. The transaction structures provide certain financial protection to AAC or Ambac UK. Generally, upon deterioration in the performance of a transaction or upon an event of default as specified in the transaction legal documents, AAC or Ambac UK will obtain certain control rights that enable them to remediate losses. These rights may enable them to direct the activities of the entity that most significantly impact the entity’s economic performance. Under the Stipulation and Order, AAC is required to obtain OCI approval with respect to the exercise of certain significant control rights in connection with policies that had previously been allocated to the Segregated Account. Accordingly, AAC does not have the right to direct the most significant activities of those LFG VIEs. • We determined that AAC or Ambac UK generally have the obligation to absorb a LFG VIE's expected losses given that they have issued financial guarantees supporting certain liabilities (and in some cases certain assets). As further described below, Ambac consolidates certain LFG VIEs in cases where we also have the power to direct the activities that most significantly the VIE’s economic impact performance due to one or more of the following: (i) the transaction experiencing deterioration and breaching performance triggers, giving AAC or Ambac UK the ability to exercise certain control rights, (ii) AAC or Ambac UK being involved in the design of the VIE and receiving control rights from its inception, such as may occur from loss remediation activities, or (iii) the transaction not experiencing deterioration, however due to the passive nature of the VIE, AAC or Ambac UK's contingent control rights upon a future breach of performance triggers is considered to be the power over the most significant activity. • A VIE is generally deconsolidated in the period that AAC or Ambac UK no longer has such control rights, which could occur the execution of remediation activities on the transaction or amortization of insured exposure, either of which may reduce the degree of control over a VIE. in connection with • Assets and liabilities of LFG VIEs that are consolidated are reported within Variable interest entity assets or Variable interest entity liabilities on the Consolidated Balance Sheets. • The election to use the fair value option is made on an instrument by instrument basis. Generally, Ambac has elected the fair value option for consolidated LFG VIE financial assets and financial liabilities, except in cases where AAC or Ambac UK was involved in the design of the VIE and was granted control rights at its inception or when the financial liabilities are primarily supported by non-financial assets. ◦ When the fair value option is elected, changes in the fair value of the LFG VIE's financial assets and liabilities are reported within Income (loss) on variable interest entities in the Consolidated Statements of Total Comprehensive Income (Loss), except for the portion of the total change in fair value of financial liabilities caused by changes in the instrument-specific credit risk which is presented separately in Other comprehensive income (loss). losses reflected ◦ In cases where the fair value option has not been elected, the LFG VIE's invested assets are fixed maturity securities and are classified as either available-for-sale or trading as defined by the Investments - Debt Securities Topic of the ASC. Available-for-sale assets are reported in the financial statements at fair value with unrealized gains and in Accumulated Other Comprehensive Income (Loss) in Stockholders' Equity. Trading assets are reported at fair value with unrealized gains and losses reflected within net income. When the fair value option has not been elected for LFG VIE long term debt obligations, the debt is carried at par less unamortized discount. Income from the LFG VIE's securities (including investment income, realized gains and losses and credit impairments as applicable) and interest expense on long term debt are reported within Income (loss) on variable the Consolidated Statements of Total Comprehensive Income (Loss). interest entities in • Upon initial consolidation of a LFG VIE, Ambac recognizes a gain or loss in earnings for the difference between: (i) the fair value of the consideration paid, the fair value of any non-controlling interests and the reported amount of any previously held interests and (ii) the net amount of the assets and liabilities consolidated, measured on a fair value basis except for contract assets and liabilities which are measured at the date of consolidation consistent with the accounting under the revenue recognition standard. Upon deconsolidation of a LFG VIE, Ambac recognizes a gain or loss for the difference between: (i) the fair value of any consideration received, the fair value of any retained non-controlling investment in the VIE and the carrying amount of any non-controlling interest in the VIE and (ii) the carrying amount of the VIE’s assets and liabilities. Gains or losses from consolidation and deconsolidation that are reported in earnings are reported within Income (loss) on variable interest entities on the Consolidated Statements of Total Comprehensive Income (Loss). • The impact of consolidating such LFG VIEs on Ambac’s balance sheet is the elimination of transactions between the consolidated LFG VIEs and AAC or Ambac UK and the inclusion of the LFG VIE’s third party assets and liabilities. For a financial guarantee insurance policy issued to a consolidated VIE, Ambac does not reflect the financial guarantee insurance policy in accordance with the related insurance accounting rules under the Financial Services — Insurance Topic of the ASC. Consequently, upon consolidation, Ambac eliminates the insurance assets and liabilities associated with the policy from the Consolidated Balance Sheets. Such insurance assets and liabilities may include premium receivables, reinsurance recoverable, recoverable, deferred unearned premiums, loss and loss expense reserves, ceded premiums payable and insurance intangible assets. For investment securities owned by AAC or Ambac UK that ceded premium, subrogation Ambac Financial Group, Inc 105 2023 Form 10-K AMBAC FINANCIAL GROUP, INC. AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) are debt instruments issued by the VIE, the associated debt and investment balances are eliminated upon consolidation. LFG VIEs which are consolidated may include recourse and non-recourse liabilities. LFG VIEs' liabilities that are insured by AAC or Ambac UK are with recourse, because the AAC or Ambac UK guarantees the payment of principal and interest in the event the issuer defaults. LFG VIEs' liabilities that are not insured by the AAC or Ambac UK are without recourse, because AAC or Ambac UK has not issued a financial guarantee and is under no obligation for the payment of principal and interest of these instruments. AAC or Ambac UK’s economic exposure to consolidated LFG VIEs is limited to the financial guarantees issued for recourse liabilities and any additional variable interests held by them. Additionally, AAC or Ambac UK’s general creditors, other than those specific policy holders which own the VIE debt obligations, do not have rights with regard to the assets of the VIEs. Ambac evaluates the net income effects and earnings per share effects to determine attributions between AAC or Ambac UK and non-controlling interests as a result of consolidating a VIE. Ambac has determined that the net income and earnings per share effect of consolidated LFG VIEs are attributable to AAC or Ambac UK’s interests through financial guarantee premium and loss payments with the VIE. The following table summarizes the carrying values of assets and liabilities, along with other supplemental information related to VIEs that are consolidated as a result of financial guarantees of Ambac UK and AAC: December 31, ASSETS: Fixed maturity securities, at fair value: Corporate obligations, fair value option Municipal obligations, trading Municipal obligations, available-for-sale (1) Total LFG VIE fixed maturity securities, at fair value Restricted cash Loans, at fair value (2) Derivative assets Other assets, including contract assets Total LFG VIE assets LIABILITIES: Long-term debt: Long-term debt, at fair value (3) Long-term debt, at par less unamortized discount Total long-term debt Derivative liabilities Cash collateral payable Other liabilities Total LFG VIE liabilities 2023 Ambac Assurance Ambac UK Total VIEs Ambac UK 2022 Ambac Assurance Total VIEs $ 2,072 $ — — 2,072 245 1,663 226 90 — — 95 95 1 — — 2 $ 2,072 $ 1,828 $ — 95 2,167 246 1,663 226 92 — — 1,828 1 1,829 239 — — 43 96 139 16 — — 2 $ 1,828 43 96 1,967 17 1,829 239 2 $ 4,296 $ 98 $ 4,394 $ 3,896 $ 157 $ 4,054 $ 2,710 $ — $ 2,710 $ 2,788 $ — $ 99 2,808 1,197 235 4 159 159 — — 1 258 2,967 1,197 235 5 — 2,788 1,048 — — 319 319 — — 5 2,788 319 3,107 1,048 — 5 $ 4,244 $ 160 $ 4,404 $ 3,836 $ 324 $ 4,160 Number of LFG VIEs consolidated 4 2 6 5 4 9 (1) Available-for-sale LFG VIE fixed maturity securities consist of municipal obligations with an amortized cost basis of $88 and $99 at December 31, 2023 and December 31, 2022, respectively.

As a result, the payment date for principal of the surplus notes was extended until OCI grants approval to make the payment. Interest will accrue, compounded on each anniversary of the original scheduled payment date or scheduled maturity date, on any unpaid principal or interest through the actual date of payment at 5.1% per annum.

AND SUBSIDIARIES Notes to Consolidated Financial Statements (Dollar Amounts in Millions, Except Share Amounts) Surplus Notes Ambac Assurance's surplus notes, with a par amount of $519 and $519 at December 31, 2023 and 2022, respectively, had a scheduled maturity of June 7, 2020, which has been extended until OCI grants approval to pay the principal of the surplus notes. The discount on surplus notes outstanding as of December 31, 2023, is being accreted into income at a weighted average effective interest rate of 6.6%. Surplus note principal and interest payments require the approval of OCI. In May 2023, OCI declined the request of AAC to pay the principal amount of the surplus notes, plus all accrued and unpaid interest thereon, on the then next scheduled payment date of June 7, 2023. As a result, the scheduled payment date for interest, and the scheduled maturity date for payment of principal of the surplus notes was extended until OCI grants approval to make the payment. Interest will accrue, compounded on each anniversary of the original scheduled payment date or scheduled maturity date, on any unpaid principal or interest through the actual date of payment, at 5.1% per annum. Holders of surplus notes have no rights to enforce the payment of the principal of, or interest on, surplus notes in the absence of OCI approval to pay such amount. The interest on the outstanding surplus notes were accrued for and AAC is accruing interest on the interest amounts following each scheduled payment date. Total accrued and unpaid interest for surplus notes outstanding to third parties was $475 at December 31, 2023. As required by the terms of surplus notes, AAC will continue to seek OCI’s approval to make payments of principal and interest on its surplus notes. OCI’s approval may be granted or denied in OCI’s sole discretion. Since the issuance of the surplus notes in 2010, OCI has declined to approve regular payments of interest on surplus notes, although the OCI has permitted two exceptional payments. Ambac can provide no assurance as to when or if surplus note principal and interest payments will be made. If OCI does not approve payments on or the acquisition of surplus notes over time, the ongoing accretion of interest on the notes may impair AAC's ability to extinguish the notes in full. Surplus notes are subordinated in right of payment to policyholder and other claims. Tier 2 Notes The Tier 2 Notes, issued on February 12, 2018, had a par value of $0 and $146 (including paid-in-kind interest of $0 and $49) at December 31, 2023 and 2022, respectively, and had a legal maturity of February 12, 2055. Interest on the Tier 2 Notes was at an annual rate of 8.50%. Other than upon payment of principal at redemption or maturity, interest payments were not due in cash on interest payment dates and were paid-in-kind and compounded on the last day of each calendar quarter. The Tier 2 Notes were recorded at a discount to par as any consideration paid that was directly related to the issuance of the Tier 2 Notes was capitalized and was part of the effective yield calculation. Ambac accreted the discount on the Tier 2 Notes into earnings at an effective interest rate of 9.9%. Ambac UK Debt The Ambac UK debt, the issued commutation of an exposure on June 18, 2019, has a par value in connection with of $41 and $41 at December 31, 2023 and 2022, and a legal maturity of May 2, 2036. Interest on the Ambac UK debt is at an annual rate of 0.00%. The Ambac UK debt was recorded at its fair value at the date of issuance. The discount on the debt is currently being accreted into income at an effective interest rate of 7.4%. Debt Redemptions and Extinguishments Net realized gains (losses) on extinguishment of debt reported in the Consolidated Statements of Total Comprehensive Income (Loss) for the years ended December 31, 2023, 2022 and 2021were $0, $81 and $33, respectively. In 2021, Sitka, issued $1,175 par amount of LIBOR plus 4.5% senior secured notes due 2026 (the “Sitka Senior Secured Notes”). In connection with the issuance and sale of the Sitka Senior Secured Notes, AAC issued a secured note to Sitka in the same amount and with the same interest rate and maturity date as the Sitka Senior Secured Notes (the "Sitka AAC Note"). Effective October 29, 2022, the Sitka AAC Note and Sitka Senior Secured Notes were wholly redeemed for $1,218 (a price equal to 103% of the principal amount plus accrued and unpaid interest) from the proceeds from the BOA Settlement Payment. Ambac recorded a loss of $53, the difference between the carrying value of the Sitka AAC Note and the redemption amount paid, excluding accrued interest. The Tier 2 Notes were partially redeemed on October 29, 2022, by approximately $213 from the BOA Settlement Payment and fully redeemed on January 15, 2023, primarily from the Nomura Settlement Payment. No gain or loss was recorded on the redemptions of the Tier 2 Notes. Refer to Note 1. Background and Business Description for further description of the BOA Settlement Payment and Nomura Settlement Payment. During the year ended December 31, 2022, surplus notes with aggregate par amount of $266 were acquired from third party holders at prices below the carrying value of the surplus notes including accrued interest, resulting in a gain of $134. During the year ended December 31, 2021, purchase agreements were executed under which AAC issued $280 aggregate principal amount (and the associated amount of accrued and unpaid interest thereon) to acquire all its remaining outstanding junior surplus notes. The Company recorded a gain of $33 arising from these purchases of junior surplus notes below their carrying values. Variable Interest Entities, Long-term Debt The variable interest entity notes were issued by consolidated VIEs. Ambac is the primary beneficiary of the VIEs as a result of providing financial guarantees on certain of the VIEs these obligations. Consequently, Ambac has consolidated variable interest entity notes and all other assets and liabilities of the VIEs. Ambac is not primarily liable for the debt obligations of these entities. Ambac would only be required to make payments on these debt obligations in the event that the issuer defaults on any principal or interest due and to the extent such obligations are guaranteed by Ambac.

The Company does not have the right to bill or collect payment on i) base commissions until the related premiums from policyholders have been collected nor ii) profit-sharing commissions until after the contract year is completed. Contract liabilities represent advance consideration received from customers related to Employer stop loss base commissions that will be recognized over time as claims servicing is performed, which typically occurs between 17 and 20 months from contract inception. During the years ended December 31, 2023, 2022 and 2021, the Company recognized revenue that was included in the contract liability balance as of the beginning of the period of $1, $1 and $1, respectively. Consolidated VIE Contract assets of $87 represent future consideration related to service concession payments for already completed services that were recognized as revenue but are not yet due. There are no contract liabilities. The change in contract assets during the year ended December 31, 2023, was primarily due to the newly consolidated VIE. As the VIE was consolidated on December 31, 2023, revenues have not yet been recognized. Ambac Financial Group, Inc 109 2023 Form 10-K AMBAC FINANCIAL GROUP, INC.
