Basis of Presentation

The Company has disclosed its significant accounting policies in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. The following significant accounting policies provide an update to those included in the Company’s Annual Report on Form 10-K.

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles ("GAAP") for interim financial reporting and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the

information and disclosures required by GAAP for annual periods. These consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2024. The accompanying consolidated financial statements have not been audited by an independent registered public accounting firm in accordance with the standards of the Public Company Accounting Oversight Board (U.S.), but in the opinion of management such financial statements include all adjustments necessary for the fair presentation of the Company’s consolidated financial position and results of operations. The results of operations for the three and six months ended June 30, 2025, may not be indicative of the results that may be expected for the year ending December 31, 2025. The December 31, 2024, consolidated balance sheet was derived from audited financial statements.

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. As additional information becomes available or actual amounts become determinable, the recorded estimates are revised and reflected in operating results.

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. 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.

Held for Sale and Discontinued Operations

The Company has separately classified the assets and liabilities of Ambac Assurance Corporation ("AAC") as held for sale as a result of AAC's pending sale and meeting specified accounting criteria. Assets and liabilities held for sale are presented separately within the Consolidated Balance Sheets with any adjustments necessary to measure the disposal group at the lower of its carrying value or fair value less costs to sell. The stockholders' equity section of the Consolidated Balance Sheet continues to be reported on an aggregate basis; equity components (including nonredeemable NCI (as defined below)) solely attributable to AAC are not presented separately.

The Company reports the results of operations of AAC as discontinued operations since the pending sale also represents a strategic shift that will have a major effect on the Company's operations and financial results. The results of discontinued operations are reported separately as Net income (loss) from discontinued operations within the Consolidated Statements of Total Comprehensive Income for the current and prior periods. AAC cash flows are reflected as Net cash provided by (used in) discontinued operations within the Consolidated Statements of Cash Flows for each period presented.

Refer to Sale of Ambac Assurance Corporation ("AAC") in Note 3. Discontinued Operation for further information.

Credit Agreement

On June 10, 2025, Ambac entered into an amendment (the "Amendment") to the $150,000 credit agreement dated as of August 1, 2024 (the "Credit Agreement"). Pursuant to the Amendment, the maturity date for amounts owed with respect to the loans made under the Credit Agreement was extended from July 31, 2025, to the earlier of (a) December 31, 2025, and (b) the date that is the three-month anniversary of the termination of the Stock Purchase Agreement, dated June 4, 2024, between AFG and American Acorn Corporation. The Amendment requires repayment of $10,000 of the principal amount of outstanding loans on October 31, 2025, in addition to any mandatory prepayment required under the Credit Agreement. Pursuant to the Amendment, a duration fee equal to 1.00% of the then outstanding loans shall be due on November 3, 2025. The Amendment also requires AFG and Cirrata Group, collectively, to maintain unrestricted cash and cash equivalent balances, determined in accordance with GAAP, of not less than $30,000 at any time. AFG paid an extension fee in an amount equal to 1.00% of the aggregate principal amount of loans outstanding under the Credit Agreement on June 10, 2025. Borrowing under the Credit Agreement for the extended term bears interest at three-month SOFR plus 7.50%.

Foreign Currency

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 $(4,821) and $0 for the six months ended June 30, 2025, and 2024, respectively. Foreign currency transaction gains/(losses) are primarily the result of Beat's transactions in currencies (primarily the U.S. dollar) other than its functional currency (the British Pound Sterling).

Noncontrolling Interests ("NCI")

Nonredeemable NCI

The total Nonredeemable NCI as of June 30, 2025 and December 31, 2024 were $168,522 and $197,755, respectively.

For Beat, the Nonredeemable NCI of $117,604 and $146,837 as of June 30, 2025 and December 31, 2024 includes the NCI share in certain operating units which are minority owned by the units' respective management teams that do not have associated put options. As of December 31, 2024, there were no put options associated with any of these minority interests and as such, the aggregate amount was classified as nonredeemable NCI on the balance sheet. During the six months ended June 30, 2025, certain NCI shares were reclassified between nonredeemable and redeemable NCI as further described under "Redeemable NCI" below. The acquisition date valuation method to determine the fair value of nonredeemable NCI was the discounted cash flow approach. The significant fair value assumptions used in the model included estimated long term revenue and expense forecasts and the discount rate. When redeemable NCI shares are no longer redeemable, such as when put options expire unused,

the NCI shares are reclassified to nonredeemable NCI with no change in carrying value.

During the three months ended June 30, 2025, Ambac paid $2,967 to purchase certain nonredeemable shares from minority interest owners, resulting in a $14,362 decrease to Nonredeemable noncontrolling interest. The difference between the consideration paid and carrying value of the nonredeemable NCI is recorded as an adjustment to additional paid-in capital.

At June 30, 2025, and December 31, 2024, AAC had 4,596 shares of issued and outstanding Auction Market Preferred Shares ("AMPS") with a liquidation preference of $114,900 relative to Ambac common shareholders (reported as nonredeemable noncontrolling interest of $50,918 on Ambac's balance sheet). See Note 5. Discontinued Operation in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 for further discussion of the AMPS.

Redeemable Noncontrolling Interest

The Xchange, All Trans, Capacity Marine, Riverton and Beat acquisitions resulted in a majority ownership of the acquired entities by Ambac. Under the terms of all the acquisition agreements, Ambac has call options to purchase the remaining interests from the minority owners (i.e., noncontrolling interests) and the minority owners have put options to sell their 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 NCI in the mezzanine section of its consolidated balance sheet. In addition, during the three months ended March 31, 2025, Ambac entered into put options with certain minority owners of the MGA/U operating entities that are majority owned by Beat. These put options are embedded in the associated NCI shares ("Option Shares"), resulting in remeasurement of the shares at fair value inclusive of the put options, and reclassification of the Option Shares from nonredeemable NCI to redeemable NCI. The change in carrying value resulting from revaluation of $10,276 is recorded as an offset to retained earnings, with a corresponding impact on earnings per share for the six months ended June 30, 2025. During the three months ended June 30, 2025, Ambac paid $1,068 as a result of exercise of put options on the Option Shares, acquiring redeemable NCI with a carrying value of $1,815. The difference between the consideration paid and carrying value of the redeemable NCI is recorded as an adjustment to additional paid-in capital.

The redeemable noncontrolling interest is remeasured on an annual basis 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

ii. the redemption value of the put option under ASC 480 as if it were exercisable at the end of the reporting period.

Any increase (decrease) in the carrying amount of the redeemable noncontrolling interest as a result of adjusting to the redemption value of the put option is recorded as an offset to retained earnings. The impact of such differences on earnings per share are presented in Note 11. Net Income Per Share.

Following is a rollforward of redeemable noncontrolling interest.

Restricted cash is cash that we do not have the right to use for general purposes and consists primarily of fiduciary cash held by Ambac's insurance distribution subsidiaries and Everspan state deposits.

Reclassifications and Rounding

Reclassifications may have been made to prior years' amounts to conform to the current year's presentation. Certain amounts and tables in the consolidated financial statements and associated notes may not add due to rounding.

Adopted Accounting Standards

There have been no new accounting standards adopted during the six months ended June 30, 2025.

Future Application of Accounting Standards and Required Disclosures

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. Ambac will adopt this ASU for the annual reporting period ending December 31, 2025. The standard is not expected to have a consequential impact on Ambac's financial statements.

Expense Disaggregation Disclosures:

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures(Subtopic 220-40). The enhanced disclosures requirements include the following:

•Disclose the amounts of certain expense categories included in each relevant expense caption. Those categories applicable to Ambac include employee compensation, depreciation, and intangible asset amortization. A relevant expense caption is an expense caption presented on the face of the income statement within continuing operations that contains any of the expense categories listed above.

•Include certain amounts that are already required to be disclosed under current GAAP in the same disclosure as the other disaggregation requirements.

•Disclose a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively.

•Disclose the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses.

The ASU is effective for annual periods beginning after December 15, 2026 and for interim reporting periods after December 15, 2027 with early adoption permitted. Ambac has not determined if it will early adopt this ASU and is evaluating the impact on Ambac's financial statements.

2. SEGMENT INFORMATION

The Company reports its results of continuing operations intwo segments: Specialty Property and Casualty Insurance and Insurance Distribution. These reportable segments offer distinct products and services as further described in Note 1. Background and Business Description. The operating entities within each segment are wholly or majority owned by separate intermediate holding companies: Everspan Holdings, LLC for Specialty Property and Casualty Insurance and Cirrata Group, LLC for Insurance Distribution. The Company's segments have separate management teams with incentive compensation structures based on segment level performance. Financial reporting for each segment is regularly provided to the Company's Chief Executive Officer, who is the chief operating decision maker ("CODM") for purposes of monitoring the businesses, assessing performance and allocating resources.

The following tables summarize the components of the Company’s total revenues and expenses, and pretax income (loss) by reportable business segment. Information provided below for “Corporate and Other” primarily relates to the operations of AFG, which will include investment income on its investment portfolio and costs to maintain the operations of AFG, including public company reporting, capital management and business development costs for the acquisition and development of new business initiatives. As a result of the Company reporting the results of operations of AAC as discontinued operations, certain corporate costs charged to AAC totaling $2,502 and $3,636 for the three months ended June 30, 2025 and 2024 and $5,265 and $7,581 for the six months ended June 30, 2025 and 2024, respectively, have been reported in Net income from continuing operations on the Consolidated Statements of Total Comprehensive Income and included in Corporate and Other in the tables below.

(1)Inter-segment revenues and inter-segment pre-tax income (loss) amounts are insignificant and are not presented separately.

3. DISCONTINUED OPERATION

Sale of Ambac Assurance Corporation ("AAC")

On June 4, 2024, AFG entered into a stock purchase agreement (the "Purchase Agreement") with American Acorn Corporation (the “Buyer”), a Delaware corporation owned by funds managed by Oaktree Capital Management, L.P., pursuant to which and subject to the conditions set forth therein, AFG will sell all of the issued and outstanding shares of common stock of AAC, a wholly-owned subsidiary of AFG, to the Buyer for aggregate consideration of $420,000 in cash (the "Sale"). The terms of the Sale as contemplated by the Purchase Agreement provide that, at the closing of the Sale (the “Closing”), Buyer will acquire complete ownership of the common stock of AAC and all of its

wholly owned subsidiaries, including Ambac Assurance UK Limited ("Ambac UK"). In connection with and pursuant to the Purchase Agreement, AFG has agreed to issue to Buyer a warrant exercisable for a number of shares of common stock, par value $0.01, of AFG representing 9.9% of the fully diluted shares of AFG’s common stock as of March 31, 2024, pro forma for the issuance of the warrant. The warrant will have an exercise price per share of $18.50 with a 6.5-year term from the date of issuance and will be immediately exercisable. On July 3, 2025, the parties to the Purchase Agreement entered into a letter agreement pursuant to which, among other things, the parties entered into a new agreement with respect to the warrant and amended certain terms of the Investor Rights Agreement (as defined in the Purchase Agreement). The Buyer continues to pursue the final outstanding regulatory approval from the Wisconsin Office of the

Commissioner of Insurance ("OCI"), which would be received only after a hearing, which has been scheduled for September 3, 2025, at or prior to which third parties would have an opportunity to object to the Sale. On or prior to August 4, 2025, representatives of certain holders of surplus notes issued by AAC filed motions to intervene in the proceedings. On July 28, 2025, the OCI staff published a memorandum including its recommendation that the Sale be approved. On July 3, 2025, AFG and the Buyer entered into an agreement to, among other matters, extend the term of the Purchase Agreement from July 3, 2025, to December 31, 2025 (subject to an automatic 90-day extension if regulatory approvals have not been obtained), to facilitate the timing of the hearing. The Buyer received approval for the change in control of Ambac UK from the U.K. Prudential Regulation Authority, which expires on October 24, 2025. See Note 5. Discontinued Operation in the Notes to Consolidated Financial Statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, for further information regarding the Sale.

AFG recorded an expected loss on sale in the Statement of Comprehensive Income (Loss) for the year ended December 31, 2024 of $(570,145), equal to the difference between the sale proceeds (net of the value of the warrants to be issued) and the carrying value of AAC's net assets held-for-sale, less expected closing costs. AFG recorded losses of $(52,960) and $(67,456) in the three and six months ended June 30, 2025, reflecting remeasurement of net assets held-for-sale and the change in fair value of the warrant to be issued to Buyer during the period, bringing the valuation allowance on held-for-sale assets to $(637,601) as of June 30, 2025. The carrying value of held-for-sale assets and liabilities, and consequently the expected loss on disposal, are subject to variability through the closing date of the Sale. Changes to the carrying value of held-for-sale assets and liabilities could arise from changes in estimates of financial guarantee losses and loss adjustment expense reserves, including subrogation recoverable; changes in the valuation of invested assets and other financial instruments carried at fair value; adverse or favorable litigation outcomes; and other operating results of AAC and its subsidiaries, including consolidated variable interest entities (“VIEs”). Additionally, at closing, net

income will be impacted by the reclassification from Accumulated Other Comprehensive Income (Loss) of net unrealized gains (losses) on available-for-sale investment securities, cumulative foreign currency translation adjustments and cumulative credit risk changes of fair value option liabilities attributable to AAC and subsidiaries, which at June 30, 2025, amounted to $(86,828).

The carrying value of held-for-sale assets and liabilities could also be impacted by payments on AAC's outstanding surplus notes. Surplus note principal and interest payments require the approval of OCI. Since the issuance of the surplus notes in 2010, OCI has declined to approve regular payments of interest on surplus notes, including AAC's request to pay full or partial interest on, and full or partial principal of, surplus notes on the scheduled payment date of June 9, 2025, although the OCI has permitted two exceptional payments in the past. As a result, the scheduled payment date for interest, and the scheduled maturity date for payment of principal of the surplus notes are 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. The interest on the outstanding surplus notes were accrued for, and AAC is accruing interest on the interest amounts following each scheduled payment date.

The components of the anticipated loss on sale, reflected in the valuation allowance on assets held-for-sale as of June 30, 2025 and December 31, 2024, are summarized below:

The following table summarizes the major classes of assets and liabilities held-for-sale on the Consolidated Balance Sheets after elimination of intercompany balances:

The following table summarizes the major line items constituting net income (loss) from discontinued operations reconciled to net income (loss) from discontinued operations presented in the Consolidated Statement of Comprehensive Income (Loss):

4. INVESTMENTS

Ambac’s invested assets are primarily comprised of of (i) fixed maturity securities classified as either available-for-sale, (ii) interests in pooled investment funds which are reported within Other investments on the Consolidated Balance Sheets and (iii)

preferred equity investments which are reported within Other investments on the Consolidated Balance Sheets. Interests in pooled investment funds are limited partner interests and are reported using the equity method.

Fixed Maturity Securities:

The amortized cost and estimated fair value of available-for-sale investments, at June 30, 2025, and December 31, 2024, were as follows:

The amortized cost and estimated fair value of available-for-sale investments, at June 30, 2025, by contractual maturity, were as follows:

Expected maturities will differ from contractual maturities because borrowers may have the right to call or prepay certain obligations with or without call or prepayment penalties.

Unrealized Losses on Fixed Maturity Securities:

The following table shows gross unrealized losses and fair values of Ambac’s available-for-sale investments, which at June 30, 2025, and December 31, 2024, did not have an allowance for credit losses. This information is aggregated by investment category and length of time that the individual securities have been in a continuous unrealized loss position, at June 30, 2025, and December 31, 2024:

Management has determined that the securities in the above table do not have credit impairment as of June 30, 2025, and December 31, 2024, based upon (i) no actual or expected principal and interest payment defaults on these securities and (ii) analysis of the creditworthiness of the issuer.

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 June 30, 2025, included in the above table resulted from the impact of increasing interest rates since the securities were purchased. Management has determined that the securities with unrealized losses are not credit impaired. Further

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 June 30, 2025, resulted primarily from an increase in interest rates since the securities were purchased. Unrealized losses of $2,599 related to 120 investment grade securities with an average unrealized loss equal to 5% of amortized cost at June 30, 2025. Management believes that the full and timely receipt of all principal and interest payment on corporate obligations with unrealized losses as of June 30, 2025, is probable.

Investment Income (Loss)

Net investment income (loss) was comprised of the following for the affected periods:

Net investment income (loss) from Other investments primarily represents income from investment limited partnerships and other equity interests accounted for under the equity method.

Net Investments Gains (Losses), including Impairments:

The following table details investment gains (losses) and impairments included in earnings within Other revenues for the affected periods:

Ambac had an allowance for credit losses of $0 and $0 at June 30, 2025, and 2024, respectively.

Ambac did not purchase any financial assets with credit deterioration for the three and six months ended June 30, 2025 and 2024.

Deposits with Regulators and Other Restrictions:

Securities carried at $32,325 and $22,861 at June 30, 2025, and December 31, 2024, 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 $765 and $800 at June 30, 2025, and December 31, 2024, were deposited as security in connection with a letter of credit issued for an office lease. Invested assets include certain fiduciary funds held by Ambac's insurance distribution subsidiaries, carried at $1,994 and $2,845 at June 30, 2025, and December 31, 2024, respectively.

Other Investments:

Ambac's investment portfolio includes a limited partnership interest in a private equity fund which seeks to generate long-term capital appreciation through venture investments in insurtech companies. The fair value of Ambac's investment in the fund was $7,486 and $7,499 as of June 30, 2025, and December 31, 2024, determined using net asset value ("NAV") as a practical expedient. Redemptions may be made quarterly with 90 days notice subject to withdrawal limitations and/or redemption fees which vary with the timing and notification of withdrawal provided by the investor. Ambac's unfunded commitments total $1,658 on this private equity fund at June 30, 2025.

Other investments also include preferred equity investments with a carrying value of $20,618 and $20,618 as of June 30, 2025, and December 31, 2024, respectively, 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. There wereno impairments recorded on these investments in the three and six months ended June 30, 2025, and $1,480 and $1,480 in the three and six months ended June 30, 2024, respectively.

5. FAIR VALUE MEASUREMENTS

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:

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.

The following table sets forth the carrying amount and fair value of Ambac’s financial assets and liabilities as of June 30, 2025, and December 31, 2024, including the level within the fair value hierarchy at which fair value measurements are categorized. As required by the Fair Value Measurement Topic of the ASC, financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

(1)Excluded from the fair value measurement categories in the table above are investment funds of $7,486 and $7,499 as of June 30, 2025, and December 31, 2024, respectively, which are measured using NAV as a practical expedient. Also excluded from the fair value amounts in the table above are equity securities with a carrying value of $20,618 and $20,618 as of June 30, 2025, and December 31, 2024, respectively, that do not have readily determinable fair values and have carrying amounts determined using the measurement alternative, and an equity method investment of $89 and $177 as of June 30, 2025, and December 31, 2024.

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 estimates in determining financial instrument values and 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, and derivative instruments. Valuation of financial instruments is performed by Ambac’s finance group using methods approved by senior financial management with consultation from third-party portfolio managers as appropriate. Preliminary valuation results are discussed with senior financial management and third-party portfolio managers as necessary 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, financial instruments valued using 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 financial management. Other valuation control procedures specific to particular portfolios are described further below.

Fixed Maturity Securities:

The fair values of fixed maturity investment securities are based primarily on market prices received independent 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.

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.

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.

Derivative Instruments:

At June 30, 2025, and December 31, 2024 Ambac has foreign currency forward contracts and holds warrants to purchase preferred stock of a development stage company. The fair value of foreign currency forwards are determined using valuation models with observable market inputs. Fair value of the warrants are determined using a standard warrant valuation model with internally developed input assumptions.

Short-term Debt:

Short-term debt consists of SOFR indexed borrowing used for partial funding of the Beat acquisition and is classified as Level 3.

Other Financial Assets:

Included in Other assets are loans carried at amortized cost, the fair values of which are estimated based upon internal valuation models and are classified as Level 3.

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 2025 and 2024. 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.

Invested assets are transferred into Level 3 when internal valuation models that include significant unobservable inputs are used to estimate fair value. All such securities that have internally modeled fair values have been classified as Level 3. Derivative instruments are transferred into Level 3 when the use of unobservable inputs becomes significant to the overall valuation. There wereno transfers of financial instruments into or out of Level 3 in the periods disclosed.

Gains and losses (realized and unrealized) relating to Level 3 assets and liabilities included in earnings for the affected periods are reported as follows:

6. INSURANCE CONTRACTS

Amounts presented in this Note relate only to Ambac’s continuing operations.

Premiums:

The effect of reinsurance on premiums written and earned was as follows:

Premium Receivables, including credit impairments:

Premium receivables at June 30, 2025, and December 31, 2024, were $71,875 and $57,222, respectively. Management evaluates premium receivables for expected credit losses ("credit impairment") in accordance with the CECL standard, which is further described in Note 2. Basis of Presentation and Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Below is a rollforward of the premium receivable allowance for credit losses for the periods presented.

At June 30, 2025, and December 31, 2024, $4,931 and $5,690 of premiums were past due.

Loss and Loss Adjustment Expense Reserves

Below is the loss and loss reserve expense roll-forward, net of subrogation recoverable and reinsurance, for the affected periods:

(1)Total losses and loss adjustment expense (benefit) is net of $(89,957) and $(96,732) for the six months ended June 30, 2025 and 2024, respectively, related to ceded reinsurance.

(2)Represents reinsurance recoverable on future loss and loss expenses. Additionally, the Balance Sheet line "Reinsurance recoverable on paid and unpaid losses" includes reinsurance recoverables (payables) of $71,031 and $35,146 as of June 30, 2025, and 2024, respectively, related to previously paid loss and loss expenses

Prior accident years losses incurred development for the three and six months ended June 30, 2025, was primarily driven by excess liability claims, whereas prior accident years losses incurred development for the three and six months ended June 30, 2024, was primarily driven by increased commercial auto loss experience.

Specialty Property & Casualty Loss Reserves

Claims Development

The following is a summary of loss and loss adjustment expense reserves, including certain components, for the Company’s major product lines by reporting segment at June 30, 2025.

(1)Other includes $27,629 related to legacy liabilities obtained from the acquisitions of Providence Washington Insurance Company, Greenwood Insurance Company, and Consolidated Specialty Insurance Company. All legacy liabilities remain obligations of affiliates of the sellers through reinsurance and contractual indemnities.

Reinsurance Recoverables, Including Credit Impairments:

Everspan’s reinsurance assets, including deferred ceded premiums and reinsurance recoverables on losses amounted to $532,027 at June 30, 2025. Credit exposure existed at June 30, 2025, with respect to reinsurance recoverables to the extent that any reinsurer may not be able to reimburse Everspan under the terms of these reinsurance arrangements. At June 30, 2025, there were ceded reinsurance balances payable of $90,557 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 Everspan.

To minimize its credit exposure to losses from reinsurer insolvencies, Everspan (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 Everspan in the event of rating agency downgrades of a reinsurer (among other events and circumstances). Everspan held letters of credit and collateral amounting to $67,265 from its reinsurers at June 30, 2025. We believe that Everspan's reinsurance counterparties, that do not currently post collateral, are well capitalized, highly rated, authorized capacity providers. Additionally, while legacy liabilities from the Providence Washington Insurance Company acquisition and the admitted carriers previously acquired by Everspan (Greenwood Insurance Company and Consolidated Specialty Insurance Company), 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.

At June 30, 2025, our topfive reinsurers represented 62.1% of 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 ourfive most significant reinsurers by amount of reinsurance recoverable as of June 30, 2025.

(1)Represents financial strength ratings from AM Best for P&C reinsurers.

(2)Represents reinsurance recoverables on paid and unpaid losses. Unsecured amounts from QBE Insurance Corporation are also supported by an unlimited, uncapped indemnity from Enstar Holdings (US).

(3)Reinsurance recoverables reduced by ceded premiums payables due to reinsurers, letters of credit, and collateral posted for the benefit of Ambac.

Everspan has uncollateralized credit exposure of $245,696 and $232,310 and has recorded an allowance for credit losses of less than a million at June 30, 2025, and December 31, 2024. The uncollateralized credit exposure includes legacy liabilities obtained from the acquisitions of PWIC and the 21st Century Companies of $27,629 and $35,146 at June 30, 2025, and December 31, 2024, respectively. All legacy liabilities, which are fully ceded to reinsurers, also benefit from an unlimited, uncapped indemnity from the respective sellers to mitigate the Company from any residual risk from these reinsurers.

7. DERIVATIVE INSTRUMENTS

The following tables summarize the gross fair values of individual derivative instruments and the impact of legal rights of offset as reported in the Consolidated Balance Sheets as of June 30, 2025, and December 31, 2024:

The following tables summarize the location and amount of gains and losses of derivative contracts in the Unaudited Consolidated Statements of Total Comprehensive Income (Loss) for the three and six months ended June 30, 2025, and 2024:

Ambac holds warrants to purchase equity shares of a development stage company and US dollar/British pound sterling foreign exchange (FX) forward contracts.

Beat utilizes foreign exchange forward contracts to partially hedge its foreign currency exposure. Beat’s functional currency is the British Pound, but a significant portion of its revenues are generated in currencies other then the British Pound, particularly the US Dollar. Beat, therefore, typically enters into forward contracts to partially hedge its exposure to fluctuations in exchange rates relative to the British Pound. In connection with our acquisition of Beat and the growth profile of its business, we will be re-evaluating our exposure to foreign currency exchange rates and related hedging strategy.

Information about FX forward contracts as of June 30, 2025 and December 31, 2024, is summarized below:

8. GOODWILL AND INTANGIBLE ASSETS

The following table presents the Company's goodwill asset.

Intangible assets and accumulated amortization are included in the Consolidated Balance Sheets, as shown below.

9. REVENUES FROM CONTRACTS WITH CUSTOMERS

As further described in the Revenue Recognition section of Note 2. Basis of Presentation and Significant Accounting Policiesin the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, the Insurance Distribution businesses have contracts that are subject to the Revenue from Contracts with Customers Topic of the ASC ("ASC 606").

The following table presents Insurance Distribution commission income recognized disaggregated by policy type for the periods presented.

For the three and six months ended June 30, 2025 and 2024, revenue of $4,472 and $—, $9,436 and $— respectively, was recognized in accordance with ASC 606 and reported in Servicing and other fees on the Consolidated Statement of Comprehensive Income (Loss).

During the six months ended June 30, 2025 and 2024, the amount of revenue recognized related to performance obligations satisfied in a previous period, inclusive of changes due to estimates was approximately $2,557 and $4,724, respectively.

Contract Assets and Liabilities

The balances of contract assets and contract liabilities with customers were as follows:

Contract assets and Contract liabilities is reported in Other Assets and Other Liabilities on the Balance Sheet

Insurance Distribution

Contract assets represent estimated future consideration related to base commissions and profit-sharing commissions that were recognized as revenue upon the placement of the policy, but are not yet due. The Company does not have the right to bill or collect payment on i) base commissions until the related premiums from policyholders has 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 six months ended June 30, 2025 and 2024, the Company recognized revenue that was included in the contract liability balance as of the beginning of the period of $473 and $479, respectively.

10. COMPREHENSIVE INCOME (LOSS)

The following tables detail the changes in the balances of each component of accumulated other comprehensive income for the affected periods:

(1)All amounts are net of tax and NCI. Amounts in parentheses indicate reductions to Accumulated Other Comprehensive Income.

(2)Represents the changes in fair value attributable to instrument-specific credit risk of liabilities for which the fair value option is elected.

The following table details the significant amounts reclassified from each component of accumulated other comprehensive income, shown in the above rollforward tables, for the affected periods:

(1) Net unrealized investment gains (losses) on available for sale securities are included in Ambac's Consolidated Statements of Comprehensive Income (Loss) as a component of Accumulated Other Comprehensive Income (Loss). Changes in these amounts include reclassification adjustments to exclude from "Other Comprehensive Income (Loss)" those items that are included are part or ":Net income for a period that has been par of "Other comprehensive income *loss) in earlier periods.

11. NET INCOME PER SHARE

As of June 30, 2025,46,400,021 shares of AFG's common stock (par value $0.01) were issued and outstanding. Common shares outstanding decreased by 106,952 during the six months ended June 30, 2025, primarily due to share repurchases partially offset by shares issued in connection with employee stock compensation.

Share Repurchases

On November 12, 2024, Ambac’s Board of Directors authorized a share repurchase program, under which Ambac may opportunistically repurchase up to $50,000 of the Company’s common shares at management’s discretion over the period ending on December 31, 2026.

The following table shows shares repurchased by year.

Earnings Per Share Calculation

The numerator of the basic and diluted earnings per share computation represents net income (loss) attributable to common stockholders adjusted by the retained earnings impacts of the noncontrolling adjustment to redemption value under ASC 480, or amendments resulting in revaluation to fair value and reclassification of NCI shares to redeemable NCI. Adjustments to the carrying value of redeemable noncontrolling interest are further described in the Redeemable NCI section of Note 1. Background and Business Description.

The following table provides a reconciliation of net income attributable to common stockholders to the numerator in the basic and diluted earnings per share calculation, together with the resulting earnings per share amounts:

The denominator of the basic earnings per share computation represents the weighted average common shares outstanding plus vested performance and restricted stock units (together, "Basic Weighted Average Shares Outstanding"). The denominator of diluted earnings per share adjusts the Basic Weighted Average Shares Outstanding for all potential dilutive common shares outstanding during the period. All potential dilutive common shares outstanding consider common stock deliverable pursuant to warrants, unvested restricted stock units and performance stock units granted under existing compensation plans. Additionally, as further described in the Redeemable NCI section of Note 1, the acquisition agreements and other agreements related to certain majority-owned subsidiaries include call and put options that, if exercised, would result in Ambac purchasing all or a portion of the remaining interests from the minority owners. Under the terms of certain of those agreements, Ambac may elect to settle a portion of its purchase with Ambac shares, which have also been considered in potential dilutive common shares outstanding.

The following table provides a reconciliation of the weighted average shares denominator used for basic net income per share to the denominator used for diluted net income per share:

(1) Performance stock units are reflected based on the performance metrics through the balance sheet date. Vesting of these units is contingent upon meeting certain performance metrics. Although a portion of these performance metrics have been achieved as of the

respective period end, it is possible that awards may no longer meet the metric at the end of the performance period.

12. INCOME TAXES

AFG files a consolidated U.S. Federal income tax return with its 80% or more owned domestic subsidiaries ("Consolidated Tax Subsidiaries"). Beat's US subsidiaries file separate U.S. Federal income tax returns as they are not 80% owned by AFG for tax purposes. AFG and its Consolidated Tax Subsidiaries also file separate or combined income tax returns in various states, local and foreign jurisdictions. The following are the major jurisdictions in which Ambac and its subsidiaries, including its foreign subsidiaries, operate and the earliest tax years subject to examination:

In accordance with the Income Tax Topic of the ASC, a valuation allowance is recognized if, based on the weight of available evidence, it is more-likely-than-not that some, or all, of the deferred tax asset will not be realized. As a result of the risks and uncertainties associated with future operating results, management believes it is more likely than not that the Company will not generate sufficient U.S. federal, state and/or local taxable income to recover its deferred tax operating assets and therefore maintains a full valuation allowance.

Consolidated Pretax Income (Loss)

U.S. and foreign components of pre-tax income (loss) were as follows:

Provision (Benefit) for Income Taxes

The components of the provision for income taxes were as follows:

As of June 30, 2025, the Company has approximately (i) $1,676,924 of federal net operating loss carryforwards, which if not utilized will begin expiring in 2030. Of this amount, $155,636 will carryforward indefinitely.

On July 4, 2025, President Trump signed into law a reconciliation bill, known informally as the One Big Beautiful Bill Act ("OBBBA" or "the Act"), which contains a number of business tax provisions, including favorable treatment for capital investment and research expenditures, expansion of the limitations on deductibility of executive compensation and modifications to U.S. taxation of foreign derived income.

The Company does not expect this legislation to have a significant impact on the Company's current operations or financial condition. As required by ASC 740, any effects of this legislation will be reflected in the Company's financial statements during the period of enactment, which will be the nine months ending September 30, 2025.

13. COMMITMENTS AND CONTINGENCIES

The Company periodically receives various regulatory inquiries and requests for information with respect to investigations and inquiries that such regulators are conducting. The Company has complied with all such inquiries and requests for information.

The Company is involved from time to time in various routine legal proceedings, including proceedings related to litigation with present or former employees. Although such litigation is routine and incidental to the conduct of its business, such litigation can potentially result in large monetary awards when a civil jury is allowed to determine compensatory and/or punitive damages.

Everspan may be subject to disputes with policyholders or other third parties regarding the scope and extent of coverage offered under Everspan's policies, including disputes relating to Everspan’s course of conduct in the handling of claims and settling or failing to settle claims (which can lead to bad faith and other forms of extra-contractual liability); be required to defend claimants in suits against its policyholders for covered liability claims; or enter into commercial disputes with its reinsurers, MGA/Us or third party claims administrators 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, including liabilities in excess of applicable policy limits.

In the ordinary course of their businesses, certain of Ambac’s subsidiaries assert claims in legal proceedings against third parties to recover losses already paid and/or mitigate future losses. The amounts recovered and/or losses avoided which may result from these proceedings is uncertain, although recoveries and/or losses avoided in any one or more of these proceedings during any quarter or fiscal year could be material to Ambac’s results of operations in that quarter or fiscal year.

From time to time, Ambac is subject to allegations concerning its corporate governance, including the manner in which it exercises control and oversight of its subsidiaries, that may lead to litigation, including derivative litigation. While the monetary impacts of addressing such allegations outside of litigation may

not be material, these charges may distract management and the Board of Directors from their principal focus on Ambac's business, strategy and objectives.

It is not reasonably possible to predict whether suits in addition to those described below will be filed or whether additional inquiries or requests for information will be made, and it is also not possible to predict the outcome of litigation, inquiries or requests for information. It is possible that there could be unfavorable outcomes in these or other proceedings. Legal accruals for litigation against the Company with losses that are probable and reasonably estimable are not material to the operating results or financial position of the Company. For the litigation matters the Company is defending that do not meet the “probable and reasonably estimable” accrual threshold and where no loss estimates have been provided below, management is unable to make a meaningful estimate of the amount or range of loss that could result from unfavorable outcomes. Under some circumstances, adverse results in any such proceedings could be material to our business, operations, financial position, profitability or cash flows. The Company believes that it has substantial defenses to the claims described below and, to the extent that these actions proceed, the Company intends to defend itself vigorously; however, the Company is not able to predict the outcomes of these actions.

Current Litigation

Dwight Jereczek and Stanley Elliott, individually and on behalf of all others similarly situated v. MBIA Inc., Ambac Financial Group, Inc., Ambac Assurance Corporation, MBIA Insurance Corporation, and National Public Finance Guarantee Corporation (United States District Court for the District of Connecticut, filed on February 12, 2025) (the "COFINA Case"). This putative class action complaint is brought by alleged former holders of bonds issued by the Puerto Rico Sales Tax Financing Corporation (“COFINA”) allegedly insured by defendants under financial guaranty insurance policies. On behalf of themselves and all persons and entities that owned such bonds between October 19, 2018, and February 12, 2019, plaintiffs allege that, in connection with the restructuring of COFINA under Title III of the Puerto Rico Oversight, Management, and Economic Stability Act, defendants orchestrated a scheme to improperly use their role in the Title III process to alter contracts with insured COFINA bondholders, resulting in such bondholders receiving less than what they contracted for under the financial guaranty insurance policies. Plaintiffs assert claims for breach of contract, unjust enrichment, and bad faith refusal to pay first-party benefits under an insurance contract. Plaintiffs seek an unspecified amount of damages with interest thereon, disgorgement of profits, a declaratory judgment of plaintiffs’ rights and defendants’ responsibilities, and a permanent injunction against violations of law. Plaintiffs filed an amended complaint on May 6, 2025. The amended complaint includes an additional claim against Ambac for breach of the implied covenant of good faith and fair dealing, and seeks punitive damages from all defendants. On May 8, 2025, the summons and amended complaint were served on Ambac. On May 29, 2025, Ambac filed a motion to dismiss the amended complaint or, in the alternative, to transfer venue to the Title III court. MBIA Inc., MBIA Insurance Corporation, and National Public Finance Guarantee Corporation (together, "National") filed

a joinder to Ambac’s request for transfer on the same day, and subsequently filed their own motion to dismiss on June 18, 2025. Plaintiffs filed their opposition to Ambac’s motion to dismiss or transfer on July 5, 2025. The deadline to file a reply in support of Ambac’s motion is August 8, 2025. Plaintiffs filed their opposition to National’s motion to dismiss on July 25, 2025; the deadline to file a reply in support of National’s motion is August 14, 2025.

CQS (UK) LLP, CQS (US), LLC, Deutsche Bank Securities Inc., FFI Fund Ltd., FYI Fund Ltd., Intermarket Corporation, Deltroit Asset Management (UK) LLP, Mudrick Stressed Credit Master Fund, L.P., Olifant Fund, Ltd., Shenkman Tactical Credit Master Fund LP, Shenkman Opportunistic Credit Master Fund LP, Four Points Multi-Strategy Master Fund, Inc., Shenkman Multi-Asset Credit Select Master Fund LP, and Three Court Master, LP v. Ambac Assurance Corporation and Ambac Financial Group, Inc. (Supreme Court of the State of New York, County of New York, Index No. 651400/2025, filed March 12, 2025) (the "Surplus Note Case"). Plaintiffs, purported owners of surplus notes issued by AAC, filed a complaint alleging that AAC and AFG breached the Settlement Agreement because AAC co-invested in Cirrata V LLC, the acquisition vehicle for Beat, without approval of the OCI. Plaintiffs sought damages in an unspecified amount allegedly sustained as a result of AAC's and AFG's breaches of the Settlement Agreement. On April 7, 2025, defendants filed a motion to dismiss the claims with prejudice. In response to defendants’ motion, the plaintiffs sought leave from the court to amend their complaint, and the amended complaint was filed on April 23, 2025. On May 7, 2025, defendants again filed a motion to dismiss the claims with prejudice, which was fully briefed on May 30, 2025. After oral argument on June 5, 2025, the court ruled from the bench in favor of AAC and AFG, dismissing plaintiffs’ amended complaint in its entirety and with prejudice. Plaintiffs’ deadline to file notice of an appeal was July 18, 2025, and no such notice was filed.

Monterey Bay Military Housing, LLC, et al. v. Ambac Assurance Corporation, et al. (United States District Court, Southern District of New York, Case No. 1:19-cv-09193-PGG, transferred on October 4, 2019 from the United States District Court, Northern District of California, San Jose Division, Case No. 17-cv-04992-BLF, filed August 28, 2017). Plaintiffs, the corporate developers of various military housing projects, filed an amended complaint on October 27, 2017 against AAC, a former employee of AAC, and certain unaffiliated persons and entities, asserting claims for (i) violation of 18 U.S.C §§ 1962(c) and 1962(d) (civil Racketeer Influenced and Corrupt Organizations Act (“RICO”) and conspiracy to commit civil RICO), (ii) breach of fiduciary duty, (iii) aiding and abetting breach of fiduciary duty, (iv) fraudulent misrepresentation, (v) fraudulent concealment and (vi) conspiracy to commit fraud. The claims relate to bonds and debt certificates (insured by AAC) that were issued to finance the renovation and construction of housing at certain military bases. Plaintiffs allege that defendants secretly conspired to overcharge plaintiffs for the financing of the projects and directed the excess profits to themselves. Plaintiffs allege defendants generated these excess profits by supposedly charging inflated interest rates, manipulating “shadow ratings,” charging unnecessary fees, and hiding evidence of their alleged wrongdoing. Plaintiffs seek,

among other things, compensatory damages, disgorgement of profits and fees, punitive damages, trebled damages and attorneys’ fees. AAC and the other defendants filed motions to dismiss the amended complaint on November 13, 2017. On July 17, 2018, the court granted AAC’s and the other defendants’ motion to dismiss the first amended complaint without prejudice. On December 17, 2018, Plaintiffs filed a second amended complaint. On February 15, 2019, AAC and the other defendants filed a motion to dismiss the second amended complaint. On September 26, 2019, the court issued a decision denying defendants’ motion to dismiss and sua sponte reconsidering its previous denial of defendants’ motion to transfer venue to the Southern District of New York (“SDNY”). On October 10, 2019, after the case was transferred to the SDNY, the defendants filed motions to vacate or reconsider the decision by the Northern District of California on the defendants’ motion to dismiss. On March 31, 2021, the court granted defendants’ motions for reconsideration and, upon reconsideration, dismissed the claims against AAC and its former employee for breach of fiduciary duty and for aiding and abetting breach of AAC’s or its former employee’s fiduciary duty; dismissed two plaintiffs’ RICO claims against AAC and its former employee; and in all other respects denied defendants’ motions. Defendants served answers to the second amended complaint on April 21, 2021, asserting several affirmative defenses, including a defense for unclean hands focused on the plaintiffs’ failure to maintain the project properties and falsification of maintenance records. On May 24, 2021, plaintiffs moved to strike defendants’ unclean hands defenses. On September 14, 2021, Magistrate Judge Sarah L. Cave, to whom plaintiffs’ motion to strike was referred for a Report and Recommendation, issued an opinion and order denying plaintiffs’ motion. On April 6, 2022, certain co-defendants filed a motion to sever the plaintiffs’ claims and to dismiss all claims except for claims asserted by the Monterey Bay plaintiffs. On January 26, 2024, the court granted the parties leave to file motions for summary judgment; opening briefs were due March 22, 2024, while oppositions are due May 31, 2024 and replies on July 12, 2024. On February 29, 2024, the court denied co-defendants’ motion to sever plaintiffs’ claims. On March 22, 2024, defendants served opening motions for summary judgment against plaintiffs’ claims in their entirety on multiple grounds, and plaintiffs served cross-motions for summary judgment on defendants’ unclean hands defenses. The parties’ summary judgment motions were fully briefed as of July 12, 2024 and are currently awaiting a decision from the Court. On December 11, 2024, the Court denied Plaintiffs’ motion for oral argument on Defendants’ motions for summary judgment, stating that it would “notify the parties if it concludes that oral argument concerning the motions for summary judgment would be productive.”

In re National Collegiate Student Loan Trusts Litigation (Delaware Court of Chancery, Consolidated C.A. No. 12111, filed November 1, 2019). On November 1, 2019, AAC became aware of a new declaratory judgment action filed by certain residual equity interest holders (“NC Owners” or “Plaintiffs”) in fourteen National Collegiate Student Loan Trusts (the “Trusts”) against Wilmington Trust Company, the Owner Trustee for the Trusts; U.S. Bank National Association, the Indenture Trustee; GSS Data Services, Inc., the Administrator; and AAC. Through this action, Plaintiffs seek a number of judicial determinations.

On January 21, 2020, the presiding Vice Chancellor entered an order consolidating the action with previously filed litigation relating to the Trusts. On February 13, 2020, AAC, the Owner Trustee, the Indenture Trustee, and other parties filed declaratory judgment counterclaims. Several parties, including Plaintiffs and AAC, filed motions for judgment on the pleadings in support of their requested judicial determinations. On August 27, 2020, the Vice Chancellor issued an opinion addressing all of the pending motions for judgment on the pleadings, which granted certain of the parties’ requested judicial determinations and denied others. He deferred judgment on still other declarations pending further factual development. The Vice Chancellor entered a series of stays to facilitate good-faith settlement discussions, the most recent of which was entered on May 2, 2023, and stayed the matter through May 5, 2023. On July 9, 2025, the Administrator filed a status report stating that certain parties continue to negotiate a resolution to some of the pending claims.

Potential Litigation

AAC’s estimates of projected losses for RMBS transactions consider, among other things, the RMBS transactions’ payment waterfall structure, including the application of interest and principal payments and recoveries, and depend in part on our interpretations of contracts and other bases of our legal rights. From time to time, bond trustees and other transaction participants have employed different contractual interpretations and have commenced, or threatened to commence, litigation to resolve these differences. From time to time AAC is also subject to allegations that it has failed to fulfill a contractual obligation or duty in respect of securities that it has issued. It is not possible to predict whether additional disputes will arise, nor the outcomes of any potential litigation. It is possible that there could be unfavorable outcomes in these or other disputes or proceedings and that our interpretations may prove to be incorrect, which could lead to changes to our estimate of loss reserves.

In the ordinary course of its businesses, AAC asserts claims in legal proceedings against third parties to recover losses already paid and/or mitigate future losses. The amounts recovered and/or losses avoided which may result from these proceedings is uncertain, although recoveries and/or losses avoided in any one or more of these proceedings during any quarter or fiscal year could be material to Ambac’s results of operations in that quarter or fiscal year.

Impact of the AAC Sale on Litigation

AAC is involved in litigation as described above. These actual and potential cases may continue after the AAC Sale is completed. Following completion of the AAC Sale, AFG will no longer have any exposure to these matters other than those in which it is a named defendant, currently the COFINA Case and the Surplus Note Case so long as it remains a defendant.
