Refer to "Description of the Business – Investments and Investment Policy" located in Part I. Item 1 of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, for further description of Ambac's investment policies and applicable regulations.

The following table summarizes the composition of Ambac’s investment portfolio, at carrying value at March 31, 2025 and December 31, 2024:

Ambac invests in various asset classes in its fixed maturity securities portfolio. Refer to Note 4. Investments to the Unaudited Consolidated Financial Statements included in Part I, Item 1 in this Form 10-Q for information about fixed maturity securities and other investments by asset class.

The following charts provide the ratings distribution of the fixed maturity investment portfolio based on fair value at March 31, 2025 and December 31, 2024. Ratings represent the lower of

ratings provided by S&P or Moody's when ratings are available from both agencies.

Premium Receivables

Ambac's premium receivables increased to $64,563 at March 31, 2025, from $57,222 at December 31, 2024. The increase is primarily due to growth in the Specialty P&C Insurance Segment, including receivables related to the programs where Everspan participates as a reinsurer.

Reinsurance Recoverable on Paid and Unpaid Losses

Ambac has reinsurance in place pursuant to 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). Those reinsurance counterparties that do not currently post collateral are well capitalized, highly rated, authorized capacity providers. Ambac benefited from letters of credit and collateral amounting to approximately $67 from its reinsurers at March 31, 2025. Additionally, while legacy liabilities from the recent Specialty P&C acquisitions were fully ceded to certain reinsurers, Everspan also benefits from an unlimited, uncapped indemnity from the respective sellers to mitigate any residual risk to these reinsurers. As of March 31, 2025 and December 31, 2024, reinsurance recoverable on paid and unpaid losses were $351,110 and $306,191, respectively primarily due to growth in the Specialty P&C Insurance Segment.

Intangible Assets, net of Accumulated Depreciation

Intangible assets primarily include (i) intangible assets established as part of acquisitions in the Insurance Distribution business of $333,848 at March 31, 2025 and (iii) indefinite-lived intangible assets in the Specialty P&C business as part of its acquisitions of $11,213 at March 31, 2025.

As of March 31, 2025 and December 31, 2024, intangible assets were $345,061 and $344,775, respectively. The increase is driven by foreign exchange rates (appreciation of the British pound), partially offset by amortization of $8,763.

Goodwill

As of March 31, 2025 and December 31, 2024, goodwill totaled $429,314 and $418,234 respectively. The increase is primarily driven by foreign exchange rates (appreciation of the British pound). All of the goodwill was assigned to the Insurance Distribution segment.

Liabilities

Loss and Loss Adjustment Expense Reserves

Loss and loss adjustment expense reserves are estimates 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 as of the balance sheet date.

Loss and loss adjustment expense reserves by line of business were as follows as of March 31, 2025 and December 31, 2024

(1)Includes $34,724 and $0 loss and loss expense reserves on a gross and net of reinsurance basis at March 31, 2025 and $35,146 and $0 loss and loss expense reserves on a gross and net of reinsurance basis at December 31, 2024 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.

The process for determining the level of loss and loss adjustment reserves is subject to certain estimates and judgments. Refer to the "Critical Accounting Policies and Estimates" and “Results of Operations” sections of Management’s Discussion and Analysis of Financial Condition and Results of Operations, in addition to Basis of Presentation and Significant Accounting Policies and Loss Reserves sections included in Note 2. Basis of Presentation and Significant Accounting Policies and Note 8. Insurance Contracts, respectively, of the Consolidated Financial Statements included in Part II, Item 8 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, for further information on loss and loss expenses.

Short and Long-term Debt

Ambac borrowed under a short-term credit facility to provide partial funding of the acquisition of Beat in 2024. The carrying value of this short term debt is $150,000 as of March 31, 2025 and December 31, 2024.

Commission Payable

Commission payables are commissions due to sub producers for placing insurance contracts on behalf of the MGAs and amounts due to UK Syndicates that provide advanced commissions to fund short term liquidity needs for MGAs. The commission payable at March 31, 2025 and December 31, 2024 was $81,017 and $71,431. The increase is primarily due to higher advance commissions due to Syndicates.

Redeemable Noncontrolling Interest (NCI)

The minority equity interests of Beat's majority owned MGA/Us were classified within nonredeemable NCI at December 31, 2024. During the three months ended March 31, 2025, Ambac entered into put options on certain of these minority interests that are embedded in the underlying equity instruments. As a result, the minority interests were reclassified from nonredeemable to redeemable and remeasured at fair value including the put options, increasing redeemable NCI by $42,180. Other changes to redeemable NCI during the quarter relate primarily to allocation of results to the minority interests, revaluation to redemption value where applicable, reclassification of certain

interests to nonredeemable due to the expiration of related put options, and the impact of foreign currency translation.
