 Re: Trust Account Termination Letter 

Dear Mr. Wolf and Ms. Gonzalez: 

Pursuant to Section 1(i) of the Investment Management Trust Agreement between Fortress Value Acquisition Corp. IV (the
“Company”) and Continental Stock Transfer & Trust Company (the “Trustee”), dated as of March 15, 2021 (the “Trust Agreement”), this is to advise you that the
Company has been unable to effect a business combination with a Target Business (the “Business Combination”) within the time frame specified in the Company’s amended and restated certificate of incorporation. Capitalized
terms used but not defined herein shall have the meanings set forth in the Trust Agreement. 
 In accordance with the terms of the Trust
Agreement, we hereby authorize you to liquidate all of the assets in the Trust Account and to transfer the total proceeds into the trust operating account at J.P. Morgan Chase Bank, N.A. to await distribution to the Public Stockholders. Subject to
the effectiveness of the amended and restated certificate of incorporation, the Company has selected [                 ] as the effective date for the purpose of
determining when the Public Stockholders will be entitled to receive their share of the liquidation proceeds. You agree to be the Paying Agent of record and, in your separate capacity as Paying Agent, agree to distribute said funds directly to the
Company’s Public Stockholders in accordance with the terms of the Trust Agreement and the Company’s amended and restated certificate of incorporation. Upon the distribution of all the funds, net of any payments necessary for reasonable
unreimbursed expenses related to liquidating the Trust Account, your obligations under the Trust Agreement shall be terminated, except to the extent otherwise provided in Section 1(j) of the Trust Agreement.
