#### Item 1.01. Entry into a Material Definitive Agreement.

#### Amendment to AAC Sale Agreement
As previously disclosed, on June 4, 2024, Ambac Financial Group, Inc., a Delaware corporation (the "<u>Company</u>") entered into a stock purchase agreement (the "<u>AAC Sale Agreement</u>") with American Acorn Corporation, a Delaware corporation owned by funds managed by Oaktree Capital Management, L.P. ("<u>Buyer</u>"), pursuant to which, subject to the conditions set forth therein, the Company will sell to Buyer all of the issued and outstanding shares of common stock, par value $2.50 per share, of Ambac Assurance Corporation, a Wisconsin stock insurance company and wholly-owned subsidiary of the Company (the "<u>AAC Transaction</u>").

On July 3, 2025, the parties to the AAC Sale Agreement entered into the First Amendment to the AAC Sale Agreement (the "<u>First Amendment</u>"), pursuant to which the parties agreed to extend the End Date (as defined in the AAC Sale Agreement) to December 31, 2025, subject to an automatic 90-day extension if regulatory approvals have not been obtained by the End Date. The description of the First Amendment in this report is qualified in its entirety by reference to the full text of the First Amendment, which is attached as Exhibit 2.1 to this Current Report on Form 8-K and is incorporated by reference herein.

#### Letter Agreement
*Overview* 

On July 3, 2025, the parties to the AAC Sale Agreement entered into a Letter Agreement (the "<u>Letter Agreement</u>"), pursuant to which, among other things, the parties entered into a new agreement with respect to the Warrant (as defined in the AAC Sale Agreement) and amended certain terms of the Investor Rights Agreement (as defined in the AAC Sale Agreement). The description of the Letter Agreement in this report is qualified in its entirety by reference to the full text of the Letter Agreement, the form of which is attached as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated by reference herein.

*Conversion of Warrant* 

As previously disclosed, pursuant to the AAC Sale Agreement, at the closing of the AAC Transaction (the "<u>Closing</u>"), the Company will issue to Buyer or its designee (the "<u>Investor</u>") the Warrant. Pursuant to the Letter Agreement, following the close of business on the six-month anniversary of the Closing (the "<u>Lock-Up Termination Date</u>") and until the expiration of the Warrant Term (as defined in the Warrant), the Investor may, once in the first six-month period following the Lock-Up Termination Date and then, once in any three-month period following the end of such six-month period, convert up to the lesser of (a) the amount of the unexercised and unconverted Warrant and (b) one-third of the original amount of the Warrant. The Warrant may be converted, at the Company's option, for (i) the number of Warrant Shares (as defined in the Warrant) for which the Investor has elected to convert or (ii) a cash payment, in each case based on the Black-Scholes Value (as defined in the Letter Agreement) of the number of Warrant Shares for which the Investor has elected to convert, or (iii) a combination of Warrant Shares and cash. The sum of all amounts paid by the Company (whether in the form of Warrant Shares or cash) to Investor or its Affiliates with respect to the Warrant upon conversion of the Warrant (including conversions in connection with a Change of Control (as defined in the Letter Agreement)) will not exceed $70 million in the aggregate.

*Standstill* 

Subject to certain exceptions, without the prior written approval of the board of directors of the Company (the "Board"), from the Closing until the date on which the Investor and its Affiliates no longer beneficially owns any portion of the Warrant, the Investor will not, and will cause each of its Affiliates not to, directly or indirectly, make any public or private proposal or offer to the Company, the Board (or any committee or member thereof) or any stockholder or group of stockholders of the Company that, if consummated, could reasonably be expected to result in a Change of Control; provided that the standstill no longer applies from and after the time at which the Company enters into a merger, consolidation, business combination, restructuring or similar transaction with any third party.

------

*Payment Upon Change of Control* 

In the event of a Change of Control of the Company, the Investor will be entitled to receive a cash payment equal to the Black-Scholes Value of the unexercised and unconverted portion of the Warrant, to be calculated on the basis set forth in the Letter Agreement.

*Investor Rights Agreement* 

As previously disclosed, pursuant to the AAC Sale Agreement, at the Closing, the Company will enter into the Investor Rights Agreement by and between the Company and the Investor. Pursuant to the Letter Agreement, the Investor Rights Agreement will be amended such that the Investor will no longer have the right to designate one director to the Board in connection with the AAC Transaction.

*Leases and Company Payments* 

The Letter Agreement provides for the parties to cooperate on certain potential arrangements with respect to the Company's office leases. The Investor also agreed to waive any claim, dispute or adjustment to the purchase price for Company Payments (as defined in the AAC Sale Agreement) from April 1, 2024 through March 31, 2025 and for certain Company Payments related to compensation from March 31, 2025 through the Closing, subject to the terms set forth in the Letter Agreement.

#### Item 3.02. Unregistered Sales of Equity Securities.
The information set forth under "Letter Agreement – Conversion of Warrant" relating to the issuance of the Warrant is incorporated by reference in this Item 3.02.

#### Item 7.01. Regulation FD Disclosure.
On July 7, 2025, the Company issued a press release to announce the First Amendment and the Letter Agreement, a copy of which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

The information furnished pursuant to this Item 7.01, shall not be deemed "filed" for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the "<u>Exchange Act</u>"), or otherwise subject to the liabilities under that Section and shall not be deemed to be incorporated by reference into any filing of the Company under the Securities Act of 1933, as amended or the Exchange Act.

We caution readers that these statements are not guarantees of future performance. Forward-looking statements are not historical facts but instead represent only our beliefs regarding future events, which may by their nature be inherently uncertain and some of which may be outside our control.

Furthermore,

------

Except as required by law, the parties undertake no obligation to update any forward-looking statements to reflect events or circumstances after the date of such statements.

NOW, THEREFORE, in consideration of the mutual and several promises and undertakings contained herein, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the Parties hereby agree as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. ***Definitions.***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) "**Black-Scholes Value**" means the value of the Warrant based on the Black-Scholes Option Pricing
Model obtained from the "OVME" function on Bloomberg Financial Markets determined as of the date that is one Business Day prior to the date of conversion of the Warrant and reflecting (i) a risk-free interest rate corresponding to the
U.S. Treasury rate for a period equal to the time between the applicable Conversion Date and the Warrant Term, (ii) an implied volatility equal to the BVOL model selected on Bloomberg Financial Markets, (iii) the underlying price per share
of Company Common Stock shall be the 20-day volume-weighted average price (using the "VWAP" function on Bloomberg Financial Markets and the "Bloomberg Definition" methodology)
(" **VWAP** "), (iv) a remaining conversion time equal to the remaining Warrant Term and (v) a dividend yield shown on the OVME screen.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) "**Change of Control**" means, with respect to the Company, a transaction or series of
transactions pursuant to which (i) a Person or group of Persons acting in concert, other than the Company or any subsidiary of the Company, becomes the beneficial owner, directly or indirectly, of fifty percent (50%) or more of the Company
Common Stock then outstanding immediately following such transaction(s) or (ii) all or substantially all of the assets of the Company are sold, except as set forth on <u>Schedule A</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) "**Conversion Date**" means, for any given conversion of the Warrant, the date on which the
conditions to such conversion as set forth in <u>Section</u> <u>2</u> of this Letter Agreement shall have been satisfied at or prior to 5:00 p.m., Eastern Time, on a Business Day, including, without limitation, the receipt by the Company
of the Conversion Notice and the Warrant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) "**Fair Market Value**" means, (i) with respect to the Company Common Stock, as of any
particular date the 20-day VWAP for the Common Stock and (ii) with respect to (x) any other property and (y) if at any time the Company Common Stock is not listed on any market or exchange of
The Nasdaq Stock Market, LLC or the New York Stock Exchange, the fair market value per share as determined in good faith by the Board; <u>provided</u> that if the Holder objects in writing to the Board's calculation of Fair Market Value within
ten (10) days of receipt of written notice thereof, the valuation dispute resolution procedure set forth in Section 7 hereof shall be invoked to determine Fair Market Value.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) "**Permitted Affiliates**" means with respect to a person, any other person that directly, or
indirectly through one or more intermediaries, controls, is controlled by or is under common control with, such first person (for purposes of this definition, "controls," "controlled by" and "under common control with"

interests); <u>provided</u> that, Permitted Affiliates shall not include any Competitor or Activist Investor.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) "**Warrant Term**" means any time after the date of the Warrant and prior to 5:00 p.m., Eastern
Time, on the date that is 78 months after the Closing or, if such day is not a Business Day, on the immediately following Business Day.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. ***Conversion Procedure.*** From the Lock-Up Termination Date and until the termination of the Warrant Term, once in the first six-month period following the Lock-Up Termination Date and once in any three-month period following the end of such six-month period, the Holder may convert up to the lesser of (a) the amount of the unexercised and unconverted Warrant and (b) one-third of the original amount of the Warrant. The Warrant may be converted at the Company's option for (i) the number of Warrant Shares for which the Holder has elected to convert or (ii) a cash payment, in each case based on the Black-Scholes Value of the number of Warrant Shares for which the Holder has elected to convert, or a combination of Warrant Shares and cash, upon surrender of the Warrant to the Company at its then principal executive offices (or an indemnification undertaking with respect to the Warrant in the case of its loss, theft or destruction), together with a Conversion Notice in the form attached hereto as <u>Exhibit A</u> (each, a "**Conversion Notice**"), duly completed (including specifying the number of Warrant Shares to be converted) and executed. Notwithstanding anything to the contrary in this Letter Agreement, the sum of all amounts paid by the Company (whether in the form of Warrant Shares or cash) to Holder or its Affiliates with respect to the Warrant upon conversion of the Warrant (including conversions in connection with a Change of Control as set forth in Section 5 of this Letter Agreement) shall not exceed $70 million in the aggregate. Unless the purchase rights represented by the Warrant shall have expired or the Warrant shall have been fully exercised or fully converted, the Company shall, at the time of delivery of the cash payment or the Warrant Shares, as applicable, deliver to the Holder a new Warrant evidencing the rights of the Holder to purchase the unexpired and unexercised or unconverted Warrant Shares called for by the Warrant. Such new Warrant shall in all other respects be identical to the Warrant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. ***Cashless Conversion.*** If the conversion of the Warrant shall be made by issuing Warrant Shares then issuable upon conversion of all or any part of the Warrant on a net basis such that, without payment of any cash consideration or other immediately available funds, the Holder shall surrender the Warrant in exchange for the number of Warrant Shares as is computed using the following formula (a cashless conversion):

X = Y \* A ÷ B

Where:

X = the number of Warrant Shares to be issued to the Holder.

Y = the total number of Warrant Shares for which the Holder has elected to convert the Warrant pursuant to Section 2 of this Letter Agreement.

------

A = the Black-Scholes Value of one Warrant Share as on the applicable Conversion Date.

B = the Fair Market Value of one Warrant Share as of the applicable Conversion Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. ***Standstill.*** Without the prior written approval of the Board, from the Closing until the date on which Investor and its Affiliates no longer beneficially owns any portion of the Warrant that remains unexercised, Investor shall not, and shall cause each of its Affiliates not to, directly or indirectly, make any public or private proposal or offer to the Company, the Board (or any committee or member thereof) or any stockholder or group of stockholders of the Company that, if consummated, could reasonably be expected to result in a Change of Control, in each case, subject to Section 3.01(c) of the form of Investor Rights Agreement attached as Exhibit D to the Stock Purchase Agreement. For clarity, this Section 4 shall not restrict Investor or its Affiliates from acquiring, selling or trading any equity or debt securities of the Company or AAC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. ***Payment Upon Change of Control***. To the extent any portion of the Warrant remains unexercised and unconverted, upon a Change of Control of the Company, the Holder shall receive from the Company, prior to or concurrently with the closing of such transaction, a cash payment equal to the Black-Scholes Value, calculated as set forth in the definition thereof, except based on (a) an implied volatility that is the greater of (i) the BVOL value shown on Bloomberg Financial Markets at the close of the first trading day following the date of public announcement of such transaction or the date such transaction becomes public knowledge (collectively, the "**Announcement**") and (ii) the simple average of the BVOL values shown on Bloomberg Financial Markets for the twenty (20) trading days prior to the Announcement and (b) a price per share of Company Common Stock equal to the greater of the 20-day VWAP prior to the Announcement and the value of the consideration per share of Company Common Stock payable pursuant to the terms of the Change of Control transaction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. ***Investor Designee.*** Investor and the Company hereby agree that Article 4 of the form of Investor Rights Agreement attached as Exhibit D to the Stock Purchase Agreement is hereby deleted in its entirety and Investor shall have no right to designate or appoint any Director or observer to the Board.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. ***Valuation Dispute Resolution.*** In the case of any dispute as to the determination of the Fair Market Value of any Company Common Stock or Warrant Shares to be issued, withheld or otherwise determined, the calculation of the Aggregate Exercise Price or any other computation or valuation of the Black-Scholes Value or the Fair Market Value required to be made hereunder or in connection herewith, in the event the Holder, on the one hand, and the Company, on the other hand, are unable to settle such dispute within ten (10) Business Days, then either party may elect to submit the disputed matter(s) for resolution by an accounting firm of nationally recognized standing as may be mutually agreed upon by the Holder and the Company. Such firm's determination of such disputed matter(s) shall be binding upon all parties absent demonstrable error. The fees and expenses of the accounting firm pursuant to this Section 7 shall be borne by the Company, on the one hand, and the Holder, on the other hand, based upon the percentage which the aggregate portion of the contested amount not awarded to each party bears to the aggregate amount actually contested by such party. For example, if the Company claims the Fair Market

------

Value is $1,000 for a given property and the Holder contests that the Fair Market Value of such property is only $500 (i.e., $500 is being contested) and if the accounting firm ultimately resolves the dispute by determining a Fair Market Value of $800 for such property, then the costs and expenses of the accounting firm will be allocated 60% (i.e., 300 ÷ 500) to the Holder and 40% (i.e., 200 ÷ 500) to the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8. ***State Street Lease.*** Notwithstanding anything set forth in the Stock Purchase Agreement, at or prior to the Closing, the Company may, at its option and subject to the terms therein, assign to Investor its right, title and interest in and to the Lease, dated March 1, 2011, by and between One State Street, LLC and the Company (as successor-in-interest to AAC), as amended by the Modification of Lease, dated September 8, 2015 (collectively, the "**State Street Lease**"); <u>provided</u> that, prior to such assignment, Investor has received approval from the Wisconsin Office of the Commissioner of Insurance ("**OCI**") to assign the State Street Lease to AAC following the Closing; <u>provided</u> <u>further</u>, that the Company shall promptly deliver to Investor written notice of any such proposed assignment, but in no event less than five (5) Business Days prior to the effective date of such assignment.

If the Company exercises its option to assign the State Street Lease pursuant to this Section 8, then (i) Investor shall accept and assume all of the Company's right, title and interest in and to, and assume all of the Company's obligations and liabilities under, the State Street Lease and (ii) the Company shall, on the effective date of such assignment, pay to Investor an amount equal to the sum of the cumulative net dollar value (after taking into account the payments to be made by the sublessee) of (i) all remaining lease payments, (ii) the projected New York City Commercial Rent Tax ("**CRT**"), (iii) the cost to maintain the insurance coverages required under the lease and (iv) projected net expenses, including porter fees and new condenser water charges, in each case, for the duration of the applicable term.

In addition, if the landlord under the One World Sublease agrees to accept a letter of credit from the Company in lieu of Investor or AAC, as applicable, and if permitted by the provider of the existing letter of credit under the One World Sublease, the Company will maintain its existing letter of credit for the benefit of Advance Magazine Publishers, Inc., D/B/A Conde Nast, until the later of (i) the termination effective date of the One World Sublease and (ii) the completion of any required restoration works thereunder; <u>provided</u> that, in the event that (a) the landlord does not accept a letter of credit from the Company or (b) the letter of credit provider does not permit the Company to maintain its existing letter of credit and, Investor or AAC , as applicable, is required to provide a letter of credit as a result of assignment of the One World Sublease or the alternative arrangement, as applicable, the Company shall provide any collateral required to be posted to support the provision of such letter of credit.

------

## Exhibit 99.1

**Exhibit 99.1** 

**Ambac Financial Group and Oaktree announce an extension to the stock purchase agreement for the Financial Guarantee business** 

**NEW YORK – July 7, 2025** – Ambac Financial Group, Inc. (NYSE: AMBC) ("Ambac") today announced the extension from July 3, 2025, to December 31, 2025 of the term of the stock purchase agreement relating to the sale of its legacy financial guarantee businesses—Ambac Assurance Corporation ("AAC") and Ambac UK ("AUK")—to funds managed by Oaktree Capital Management, L.P. ("Oaktree") for $420 million in cash.

Both Ambac and Oaktree remain fully committed to closing the transaction. Oaktree continues to work with the Wisconsin Office of the Commissioner of Insurance (the "OCI") to satisfy its remaining closing conditions and obtain final regulatory approval.

"We continue to await final regulatory approval for this strategic transaction and remain aligned with Oaktree and confident in completing the sale," said Claude LeBlanc, President and CEO of Ambac. "This transaction remains the capstone to our transformation into a pure-play specialty P&C insurance platform, and we look forward to closing it as soon as practicable."

"Oaktree has been actively working towards, and is committed to, obtaining the final regulatory approval from the OCI to close on the acquisition of AAC and AUK," said Oaktree Managing Director Greg Share. "We look forward to closing this transaction once such approval is received."

In addition to the extension, Ambac and Oaktree have agreed to a conversion right for the warrant to purchase Ambac common stock that Oaktree is receiving at the closing of the transaction. Ambac and Oaktree have also agreed to arrangements with respect to Ambac's existing lease obligations and on the treatment of certain expenses allocated to AAC prior to the closing of the transaction. Full details of the amendment will be disclosed in a Current Report on Form 8-K to be filed by Ambac with the SEC today.
