AMBAC FINANCIAL GROUP, INC. ANNOUNCES THIRD

QUARTER NET INCOME OF $213.5 MILLION, UP 22%

Third Quarter Net Income Per Diluted Share of $1.98, up 23%,

Third Quarter Credit Enhancement Production⁽¹⁾ $216.2 million, down 16%

NEW YORK, October 25, 2006—Ambac Financial Group, Inc. (NYSE: ABK) (Ambac) today announced third quarter 2006 net income of $213.5 million, or $1.98 per diluted share. This represents a 22% increase from third quarter 2005 net income of $175.1 million, and a 23% increase in net income per diluted share from $1.61 in the third quarter of 2005.

Net Income Per Diluted Share

Net income and net income per diluted share are computed in conformity with U.S. generally accepted accounting principles (GAAP). However, many research analysts and investors do not limit their analysis of our earnings to a strictly GAAP basis. In order to assist investors in their understanding of quarterly results, Ambac provides other information.

Earnings measures reported by research analysts exclude the net income impact of net gains and losses from sales of investment securities and mark-to-market gains and losses on credit, total return and non-trading derivative contracts (collectively “net security gains and losses”) and certain other items. Certain research analysts and investors further exclude the net income impact of accelerated premiums earned on guaranteed obligations that have been refunded and other accelerated earnings (“accelerated earnings”). During the third quarter 2006, net security gains and losses had the effect of increasing net income by $6.5 million, $0.06 on a per diluted share basis. Accelerated earnings had the effect of increasing net income by $14.5 million, or $0.13 per diluted share for the third quarter 2006. Table I, below, provides third quarter and nine-month comparisons of earnings for 2006 and 2005.

(b) Operating and core earnings are non-GAAP measures. See footnote 2 on page 10.

Commenting on the overall results, Ambac Chairman and Chief Executive Officer, Robert J. Genader, noted, “I am pleased with the results given the challenging environment we have faced during much of the year. We are currently witnessing a solid level of deal inquiries and opportunities across most of our business segments. Domestic public finance, however, continues to pose a challenge given the decline in issuance and intensified pricing pressures. We remain steadfast in judiciously allocating our capital to transactions that enable us to continue to deliver superior returns.”

Revenues

Highlights

• Credit enhancement production⁽¹⁾ in the third quarter of 2006 was $216.2 million, down 16% from the third quarter of 2005 which came in at $256.6 million. Growth in international was more than offset by declines in U.S. public finance and U.S. structured finance.

Credit enhancement production⁽¹⁾ for the nine months of 2006 of $980.7 million was 15% higher than credit enhancement production of $853.5 million in the same period of 2005, driven by growth in the international and U.S. structured finance markets during the nine-month period.

Table II, below, provides the third quarter and nine-month comparisons of credit enhancement production by market segment for 2006 and 2005.

• In public finance, Ambac’s premium production was lower as overall market issuance, as reported by third party sources, was down approximately 14% quarter on quarter. The decline in issuance for the quarter was driven by significantly reduced refunding issuance. The new money component of issuance for the quarter was relatively flat as compared to the third quarter of 2005. Contributing to the lower premium production was increased competition from other financial guarantors and the mix of business coming to market. We note that fewer highly structured transactions commanding stronger pricing have come to market recently. Ambac had healthy writings in the stadium financing sector during the quarter and health care writings were strong albeit lower than in the comparable prior quarter.

U.S. structured finance production during the quarter was lower as increased writings in auto securitizations and pooled debt obligations were more than offset by lower commercial asset-backed securitizations and mortgage-backed securities. Competition from the senior/subordinated market remains challenging and spreads remain tight across most asset classes of U.S. structured finance.

International production was stronger but compares to a relatively light prior year quarter. The international quarter was highlighted by two deals out of the U.K, one an infrastructure transaction and the other a structured finance transaction. Ambac continues to see attractive opportunities across diverse geographic regions and asset classes outside of the U.S.

• Net premiums written in the third quarter of 2006 of $186.0 million were 9% lower than net premiums written of $203.6 million in the same period of 2005. Gross premiums written in the third quarter of 2006 and 2005 were $212.3 million and $237.9 million, respectively. The decreases in net and gross premiums written are primarily attributable to lower up-front premiums collected on U.S. public finance business written during the third quarter of 2006. Ceded premiums as a percentage of gross premiums written were 12.4% and 14.4% for the third quarter of 2006 and 2005, respectively.

Net premiums written for the nine months of 2006 of $669.4 million were 8% lower than net premiums written of $728.0 million in the same period of 2005. Excluding the impact of return premiums from reinsurance cancellations in each of the periods ($37.0 million in the first quarter of 2006 and $55.8 million in the first quarter of 2005), net premiums written are down 6% period on period primarily due to less up-front premiums collected on U.S. public finance business written during 2006.

• Net premiums earned and other credit enhancement fees for the third quarter of 2006 were $214.5 million, which represented a 7% decrease from the $231.1 million earned in the third quarter of 2005. The decrease was driven by lower accelerated premiums from refundings and policy termination fees offset by increased normal premiums and other credit enhancement fees earned in U.S. public finance and U.S. structured finance.

Net premiums earned include accelerated premiums, which result from refundings, calls and other accelerations recognized during the quarter. Accelerated premiums were $24.5 million in the third quarter of 2006, down 50% from $48.9 million in accelerated premiums in the third quarter of 2005. The third quarter 2005 accelerated premiums were impacted by one large refunded transaction, representing almost half of the total accelerated amount in that quarter.

Net premiums earned and other credit enhancement fees for the first nine months of 2006 were $647.9 million, flat to $648.6 million earned in the first nine months of 2005. Accelerated premiums were $86.9 million for the nine-month period of 2006, down 20% from $107.9 million in accelerated premiums for the comparable period of 2005. Accelerated premiums in 2006 and 2005 include $7.7 million and $4.5 million, respectively, related to the impact of reinsurance cancellations which occurred in the first quarter of the respective years.

A breakdown of net premiums earned and other credit enhancement fees by market segment for 2006 and 2005 are included below in Table IV. Normal net premiums earned exclude accelerated premiums that result from refundings, calls and other accelerations.

Public finance earned premiums, before accelerations, grew 3% quarter on quarter. Earned premium growth in this segment has been negatively impacted by declining issuance and competitive pricing throughout 2006, compounded by the high level of refunding activity in Ambac’s public finance book.

Structured finance earned premiums and other credit enhancement fees grew 12%. The rate of growth in structured finance has improved as the recent level of writings in asset classes such as commercial asset-backed securities, auto securitizations and pooled debt obligations has increased. Narrow credit spreads and high prepayment speeds in the mortgage-backed and home equity book of business and early terminations of transactions in other structured finance sectors continue to partially offset the positive effects of new business writings.

International earned premiums and other credit enhancement fees decreased by 6%. The decline was driven primarily by significant paydowns and calls over the past several quarters and the recent business mix which has trended towards long-dated infrastructure transactions that earn premiums over a longer period of time than typical structured finance exposures.

• Net investment income (including net investment income from VIEs) for the third quarter of 2006 was $120.2 million, representing an increase of 9% from $110.6 million in the comparable period of 2005. This increase was due primarily to growth in the investment portfolio driven by the ongoing collection of financial guarantee premiums and fees and a $200 million capital contribution from the parent company in the fourth quarter of 2005, partially offset by a $5.3 million net positive adjustment booked in the third quarter 2005 for municipal bonds within the portfolio that had been pre-refunded. Investment income from VIEs is offset by interest expense on VIEs, shown separately in the Consolidated Statements of Operations.

Net investment income (including net investment income from VIEs) for the nine months of 2006 was $351.2 million, representing an increase of 11% from $317.1 million in the comparable period of 2005, primarily as a result of the reasons provided above.

Ambac Third Quarter 2006 Earnings/6

• Financial services revenues. The financial services segment is comprised of the investment agreement business and the derivative products business. Gross interest income less gross interest expense from investment and payment agreements plus results from the derivative products business, excluding net realized investment gains and losses and unrealized gains and losses on total return swaps and non-trading derivative contracts, was $13.3 million in the third quarter of 2006, down 22% from $17.1 million in the third quarter of 2005. The decrease was primarily due to lower mark-to-market gains included within derivative products revenues in the third quarter 2006 relative to the comparable prior quarter, partially offset by higher investment agreement revenues from improving spreads during that quarter.

Financial services revenues were $35.8 million in the first nine months of 2006, up 1% from the $35.4 million of revenues in the first nine months of 2005.

Expenses

Highlights

• Financial guarantee expenses of $40.4 million for the third quarter of 2006 decreased by 69% from the $128.6 million of expenses for the same quarter of 2005. Financial guarantee loss and loss expenses were ($2.5) million in the third quarter of 2006 down from $89.1 million in the third quarter of 2005. The third quarter 2005 loss provision resulted primarily from our exposure to municipal credits impacted by Hurricane Katrina. The current quarter’s negative loss provision is primarily the result of a release of a portion of the Katrina provision partially offset by increased reserves, primarily in the U.S. public finance sector. See “Loss Reserve Activity,” below, for additional information on losses. Net underwriting and operating expenses of the financial guarantee segment totaled $30.2 million in the third quarter of 2006, up 9% from $27.8 million in the third quarter of 2005 primarily due to increased compensation expense.

Interest expense on VIE notes amounting to $12.8 million and $11.6 million in the third quarter of 2006 and 2005, respectively, result from the consolidation of certain trusts that Ambac has insured and consolidated under accounting pronouncement FIN 46.

Financial guarantee expenses of $147.7 million for the nine months of 2006 decreased 43% from $259.2 million for the same period of 2005. The decrease results primarily from lower loss expenses partially offset by higher compensation expenses during the period.

Loss Reserve Activity

• Case basis loss reserves (loss reserves for exposures that have defaulted) decreased $12.0 million during the third quarter of 2006 from $138.7 million at June 30, 2006 to $126.7 million at September 30, 2006. The decrease was driven primarily by claim payments made during the quarter amounting to $8.9 million.

Ambac Third Quarter 2006 Earnings/7

• Active credit reserves (“ACR”) are established for probable and estimable losses due to credit deterioration on adversely classified insured transactions. Ambac continuously monitors its insured portfolio actively seeking to mitigate claims. The ACR increased by $0.6 million during the quarter, from $147.0 million at June 30, 2006 to $147.6 million at September 30, 2006. The increase was driven by increased reserves on certain credits within the U.S. public finance and structured finance portfolios, offset by a $35.6 million reduction in the ACR for Hurricane Katrina impacted credits. At September 30, 2006, the specific Hurricane Katrina-related provision amounts to $50.5 million, down from $90.4 million at June 30, 2006. The decrease is primarily due to significant state and federal support recently provided to the region, particularly the greater New Orleans area. Ambac did not pay any Katrina-related claims during the quarter.

• Provision for income taxes for the third quarter of 2006 amounted to $83.6 million, an effective tax rate of 28.1%. This compares to the third quarter of 2005 tax provision of $51.9 million, an effective tax rate of 22.8%. The increased tax rate in 2006 was due to the net release of tax reserves in the third quarter 2005 and higher taxable income resulting from improved financial guarantee underwriting results in the third quarter 2006 relative to the comparable prior period primarily as a result of Hurricane Katrina related loss activity.

Provision for income taxes for the nine months of 2006 amounted to $252.5 million, an effective tax rate of 27.3%. This compares to the nine months of 2005 tax provision of $193.1 million, an effective tax rate of 26.1%. The increased tax rate in 2006 is explained above.

Other Items

• Total net securities gains/(losses) for the third quarter of 2006 were $9.9 million, or $0.06 per diluted share; consisting of net realized gains on investment securities of $7.9 million, net mark-to-market gains on credit and total return derivatives of $2.1 million and net mark-to-market losses on non-trading derivative contracts of ($0.1) million. For the third quarter of 2005, net securities gains/(losses) were $14.5 million, or $0.08 per diluted share; consisting of net realized gains on investment securities of $9.5 million, net mark-to-market gains on credit and total return derivatives of $3.9 million and net mark-to-market gains on non-trading derivative contracts of $1.1 million.

Total net securities gains/(losses) for the nine months of 2006 were $74.4 million, or $0.44 per diluted share; consisting of net realized gains on investment securities of $57.5 million, net mark-to-market gains on credit and total return derivatives of $16.5 million and net mark-to-market gains on non-trading derivative contracts of $0.4 million. Approximately $51 million of the net realized gains on investment securities relate to cash recoveries received during the year related to a security in the investment agreement portfolio that had been written down in 2002 and 2003. For the nine months of 2005, net securities gains were $53.1 million, or $0.27 per diluted share; consisting of net realized gains on investment securities of $10.8 million, mark-to-market losses on credit derivatives and total return swaps of ($7.0) million and net mark-to-market gains on non-trading derivative contracts of $49.3 million. The mark-to-market gains on non-trading derivative contracts relate almost entirely to interest rate hedge contracts in Ambac’s investment agreement business that were redesignated to meet the technical requirements of FAS 133 as of July 1, 2005.

• As of September 30, 2006, stockholders’ equity was $6.01 billion, a 12% increase from year-end 2005 stockholders’ equity of $5.37 billion. The increase was primarily the result of net income during the period.

Ambac Third Quarter 2006 Earnings/10

Footnotes

(1) Credit enhancement production, which is not promulgated under GAAP, is used by management, equity analysts and investors as an indication of new business production in the period. Credit enhancement production, which Ambac reports as analytical data, is defined as gross (direct and assumed) up-front premiums plus the present value of estimated installment premiums on insurance policies and structured credit derivatives issued in the period. The discount rate used to measure the present value of estimated installment premiums was 6.0% and 7.0% during the third quarter of 2006 and 2005, respectively. The definition of credit enhancement production used by Ambac may differ from definitions of credit enhancement production used by other public holding companies of financial guarantors. The following table reconciles credit enhancement production to gross premiums written calculated in accordance with GAAP:

$-millions	Third Quarter						Nine Months
	2006			2005			2006			2005

(2) Operating earnings and core earnings are not substitutes for net income computed in accordance with GAAP, but are useful measures of performance used by management, equity analysts and investors. Operating earnings measures income from operations excluding the impact of investment portfolio realized gains and losses, mark-to-market gains and losses from certain non-trading derivative instruments and certain other items. Core earnings further exclude the impact of refundings, calls and other accelerations. The definitions of operating earnings and core earnings used by Ambac may differ from definitions of operating earnings and core earnings used by other public holding companies of financial guarantors.
