AMBAC FINANCIAL GROUP INC

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 insuring variable interest entities (“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.

The following table provides a comparison of total, adversely classified credits ("ACC") and watch list credit net par outstanding in the insured portfolio at June 30, 2024 and December 31, 2023.

The decrease in total and ACC net par outstanding resulted from active de-risking, scheduled maturities, amortizations, refundings and calls and a strengthening of the USD versus the GBP of $93 on the total net par outstanding. Additionally, we upgraded (from ACC to Watch List) one credit that has net par outstanding of $542 at June 30, 2024.

The following table provides a breakdown of guaranteed net par outstanding by market at June 30, 2024 and December 31, 2023.

(1) Internal credit ratings are provided solely to indicate the underlying credit quality of guaranteed obligations based on the view of Ambac. In cases where Ambac has insured multiple tranches of an issue with varying internal ratings, or more than one obligation of an issuer with varying internal ratings, a weighted average rating is used. 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 decreased $68 from December 31, 2023. Exposures are impacted by changes in foreign exchange rates ($59 decrease during the six months ended June 30, 2024), 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) was 32% at June 30, 2024, and 31% at December 31, 2023. 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 $292 and a median net par outstanding of $5.

Ratings Distribution

The following charts provide a rating distribution of net par outstanding based upon internal Ambac credit ratings(1) and a distribution by bond type of Ambac's below investment grade ("BIG") net par exposures at June 30, 2024 and December 31, 2023. BIG is defined as those exposures with an Ambac internal credit rating below BBB-:

Note: AAA is less than 1% in both periods.

Summary of Below Investment Grade Exposure:

The net decline in below investment grade exposures is primarily due to de-risking activities and an upgrade of a sub-sovereign exposure.

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 increase in the future.
