Ambac Reports Second Quarter 2021 Results

NEW YORK, NY, August 5, 2021 (BUSINESS WIRE) -- Ambac Financial Group, Inc. (NYSE: AMBC) ("Ambac" or "AFG")), a financial services holding company, today reported a net loss attributable to common stockholders of $29 million or $0.63(1) per diluted share and adjusted loss(2) of $13 million or $0.30 per diluted share for the quarter ended June 30, 2021. This compares to net Income attributable to common stockholders of $17 million or $0.08 per diluted share and adjusted earnings of $41 million or $0.59 per diluted share in the first quarter of 2021. Book value per share decreased $0.01 to $23.01 and adjusted book value per share(2) decreased $0.41 to $19.25 from March 31, 2021, to June 30, 2021.

Results for the second quarter, as compared to the first quarter of 2021, were primarily driven by the realization in the first quarter of a $37 million gain from the Corolla and junior surplus note exchanges. In addition, a loss from interest rate derivatives, compared to a gain in the first quarter, and an increase in the provision for deferred taxes more than offset a losses and loss expense benefit compared to an expense in the first quarter.

Claude LeBlanc, President and Chief Executive Officer, stated, “We made significant progress towards our derisking goals during the second quarter as evidenced by the $1.0 billion or 8.2% reduction to our adversely classified and watch list credits. Additionally, our endorsement of Puerto Rico's plan support agreements provide Ambac a path towards resolving our largest distressed credit exposure and materially advances our legacy businesses towards a stable run-off." Mr. LeBlanc continued, "During this transition year, I am very pleased with our derisking achievements and the significant progress we have made with the launch of our specialty property and casualty insurance platform strategy."

Net Premiums Earned

During the second quarter of 2021, net premiums earned were $11 million compared to $14 million in the first quarter of 2021. The decrease in earned premium related to lower normal premiums earned driven by a smaller

1

reduction in the allowance for premiums receivable compared to the first quarter of 2021 and the continued run-off of the insurance portfolio.

Net Investment Income and Net Realized Investment Gains

Net investment income for the second quarter of 2021 was $42 million compared to $49 million for the first quarter of 2021. Net investment income includes interest and net discount accretion on fixed maturity securities classified as available-for-sale and net gains on pooled investment funds, including changes in fair value of the funds' net assets.

Net investment income in the second quarter of 2021 was driven by gains on pooled investment funds of $20 million compared to gains of $27 million for the first quarter of 2021. Ambac's portfolio of pooled funds primarily consist of investments in hedge funds, asset-backed securities, public and private equity, high-yield bonds, leveraged loans, emerging markets debt and private credit. Second quarter 2021 pooled fund results reflect overall strong, but relatively lower equity and hedge fund returns partially offset by gains from emerging market debt compared to the first quarter of 2021.

Net realized investment losses were $2 million for the second quarter of 2021, which were primarily related to FX. The net realized investment gains of $2 million for the first quarter of 2021 included a $4 million gain from AFG's exchange of its equity interest in Corolla Trust for surplus notes of Ambac Assurance Corporation ("AAC").

Losses and Loss Expenses (Benefit) and Loss Reserves

Losses and loss expenses ("Insured Losses") for the second quarter of 2021 were a benefit of $26 million, compared to an expense of $8 million for the first quarter of 2021.

The following table provides Insured Losses (Benefit) by category for the three-month periods ended June 30, 2021 and March 31, 2021:

	Three Months Ended
($ in millions)	June 30, 2021		March 31, 2021
Structured finance	$	(16)	$	(8)
Domestic public finance	(11)		9
Other	1		6
Total losses and loss expenses (benefit)	$	(26)	$	8

The second quarter structured finance benefit of $16 million reflected improved credit factors and the positive impact of lower interest rates on excess spread in the insured RMBS portfolio, partially offset by the negative impact of lower discount rates and incremental loss expense costs. The structured finance benefit for the first quarter of $8 million reflected improved credit factors.

The second quarter domestic public finance benefit of $11 million related to general credit improvements in the insured public finance portfolio, particularly with regards to a few specific credits, partially offset by higher loss expense costs. The impact of the Puerto Rico plan support agreements signed by AAC on July 27th were reflected in second quarter public finance reserves. The first quarter 2021 domestic public finance Insured Losses of $9 million were related to an increase in Puerto Rico reserves due to changes in assumptions, partially offset by the favorable impact of higher discount rates.

During the second quarter of 2021 Insured Losses paid (net of reinsurance) were $13 million, including $43 million of loss and expense payments, partially offset by $30 million of subrogation received. During the first quarter of 2021, Insured Losses paid (net of reinsurance) were $25 million including $50 million of loss and expense payments, partially offset by $25 million of subrogation received. The decrease in losses paid in the second quarter relative to the first quarter related to claim payments on Puerto Rico insured bonds made in the first quarter of 2021.

Loss and loss expense reserves (gross of reinsurance) were $(456) million at June 30, 2021, and $(414) million at March 31, 2021, which were net of $1.741 billion and $1.748 billion, respectively, of estimated subrogation recoveries related to AAC's pursuit of legal remedies to seek redress for breaches of RMBS representations and warranties.

Net Gains (Losses) on Derivative Contracts

Net losses on derivative contracts of $11 million for the second quarter of 2021 compared to gains of $25 million for the first quarter of 2021 were driven by lower forward interest rates in the second quarter. The interest rate derivatives portfolio is positioned to benefit from rising interest rates as a partial economic hedge against interest rate exposure in AAC's insured and investment portfolios. Higher counterparty credit adjustments on uncollateralized derivative assets also contributed to the second quarter of 2021 loss, while credit adjustments declined in the prior quarter.

Other Income

Other income, which includes commission revenues earned by Xchange, was $7 million for the second quarter of 2021 compared to $5 million for the first quarter of 2021.

Expenses

Operating expenses for the second quarter of 2021 were $28 million compared to $33 million in the first quarter of 2021. The decrease in operating expenses was mostly driven by cyclical compensation expenses and advisor costs related to the Corolla exchange incurred in the first quarter of 2021.

Interest expense was $50 million in both the second quarter of 2021 and first quarter of 2021.

Taxes

The provision for income taxes increased to $11 million in the second quarter of 2021 compared to only $2 million in the first quarter of 2021. The $9 million increase related to a higher provision for deferred taxes resulting from the UK enactment of a tax increase from 19% to 25% effective April 1, 2023.

Total Ambac Financial Group, Inc. Stockholders' Equity

Stockholders’ equity at June 30, 2021, was $1.06 billion, or $23.01 per share compared to $1.06 billion or $23.02 per share as of March 31, 2021. An increase in unrealized gains on securities of $26 million mostly offset the second quarter net loss of $29 million.

Financial Guarantee Insured Portfolio

The financial guarantee insurance portfolio net par amount outstanding declined 3.9% during the quarter ended June 30, 2021, to $30.2 billion from $31.4 billion at March 31, 2021 due to active de-risking and natural runoff.

Adversely Classified and Watch List Credits decreased in the second quarter of 2021 by $1.0 billion or 8.2% to $11.1 billion at June 30, 2021, from $12.1 billion at March 31, 2021, due to de-risking activity and natural runoff.

Subsequent Event

On July 6, 2021 Sitka Holdings, LLC a wholly-owned subsidiary of Ambac, issued $1,175 million par of LIBOR plus 4.50% Floating Rate Senior Secured Notes due 2026. The outstanding Ambac LSNI Notes were fully redeemed from the proceeds of this offering and other available temporary sources of liquidity. The issuance was conducted in light of favorable market conditions and to extend maturity of AAC's senior secured debt by approximately three years. While Ambac expects to resolve the remaining litigations brought by AAC to recover losses on insured residential mortgage-backed securities well in advance of the maturity of the senior secured notes, Ambac believes that an extended maturity date will provide increased financial flexibility during the pendency of such litigations.

Non-GAAP Financial Data

In addition to reporting Ambac’s quarterly financial results in accordance with GAAP, the Company currently reports two non-GAAP financial measures: adjusted earnings and adjusted book value. The most directly comparable GAAP measures are net income attributable to common stockholders for adjusted earnings and Total Ambac Financial Group, Inc. stockholders’ equity for adjusted book value. A non-GAAP financial measure is a numerical measure of financial performance or financial position that excludes (or includes) amounts that are included in (or excluded from) the most directly comparable measure calculated and presented in accordance with GAAP. We are presenting these non-GAAP financial measures because they provide greater transparency and enhanced visibility into the underlying drivers of our business. Adjusted earnings and adjusted book value 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.

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 and other considerations, we utilized a 0% effective tax rate for non-GAAP adjustments; which is subject to change.

The following paragraphs define each non-GAAP financial measure and describe why it is useful. A reconciliation of the non-GAAP financial measure and the most directly comparable GAAP financial measure is also presented below.

Adjusted Earnings (Loss). Adjusted earnings (loss) is defined as net income (loss) attributable to common stockholders, as reported under GAAP, adjusted on an after-tax basis for the following:

•Non-credit impairment fair value (gain) loss on credit derivatives: Elimination of the non-credit impairment fair value gains (losses) on credit derivatives, which is the amount in excess of the present value of the expected estimated credit losses. Such fair value adjustments are affected by, and in part fluctuate with changes in market factors such as interest rates and credit spreads, including the market’s perception of Ambac’s credit risk (“Ambac CVA”), and are not expected to result in an economic gain or loss. These adjustments allow for all financial guarantee contracts to be accounted for consistent with the Financial Services – Insurance Topic of ASC, whether or not they are subject to derivative accounting rules.

•Insurance intangible amortization: Elimination of the amortization of the financial guarantee insurance intangible asset that arose as a result of Ambac’s emergence from bankruptcy and the implementation of Fresh Start reporting. This adjustment ensures that all financial guarantee contracts are accounted for consistent with the provisions of the Financial Services – Insurance Topic of the ASC.

4

•Foreign exchange (gains) losses: Elimination of the foreign exchange gains (losses) on the re-measurement of assets, liabilities and transactions in non-functional currencies. This adjustment eliminates the foreign exchange gains (losses) on all assets, liabilities and transactions in non-functional currencies, which enables users of our financial statements to better view the results without the impact of fluctuations in foreign currency exchange rates and facilitates period-to-period comparisons of Ambac's operating performance.

Adjusted loss was $13 million, or $0.30 per diluted share, for the second quarter 2021 as compared to adjusted earnings of $41 million or $0.59 per diluted share, for the first quarter of 2021.

The following table reconciles net income (loss) attributable to common stockholders to the non-GAAP measure, adjusted earnings (loss), for the three-month periods ended June 30, 2021, and March 31, 2021, respectively:

	Three Months Ended

Weighted-average diluted shares outstanding (in millions)			46.6				46.9

1 Per Diluted share includes the impact of adjusting the Xchange related noncontrolling interest to current redemption value

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:

•Non-credit impairment fair value losses on credit derivatives: Elimination of the non-credit impairment fair value loss on credit derivatives, which is the amount in excess of the present value of the expected estimated economic credit loss. GAAP fair values are affected by, and in part fluctuate with, changes in market factors such as interest rates, credit spreads, including Ambac’s CVA that are not expected to result in an economic gain or loss. These adjustments allow for all financial guarantee contracts to be accounted for within adjusted book value consistent with the provisions of the Financial Services—Insurance Topic of the ASC, whether or not they are subject to derivative accounting rules.

•Insurance intangible asset: Elimination of the financial guarantee insurance intangible asset that arose as a result of Ambac’s emergence from bankruptcy and the 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.

•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.

•Net unrealized investment (gains) losses in Accumulated Other Comprehensive Income:Elimination of the unrealized gains and losses on the Company’s investments that are recorded as a component of accumulated other comprehensive income (“AOCI”). The AOCI component of the fair value adjustment on the investment portfolio may differ from realized gains and losses ultimately recognized by the Company based on the Company’s investment strategy. This adjustment only allows for such gains and losses in adjusted book value when realized.

Adjusted book value was $889 million, or $19.25 per share, at June 30, 2021, as compared to $908 million, or $19.66 per share, at March 31, 2021. The decrease in adjusted book value for the second quarter of 2021 was primarily attributable to the adjusted loss (net of earned premium) partially offset by the impact of discount rates.

The following table reconciles Total Ambac Financial Group, Inc. stockholders’ equity to the non-GAAP measure adjusted book value as of each date presented:
