AMENDED AND RESTATED
CERTIFICATE OF INCORPORATION
OF
ANZU SPECIAL ACQUISITION CORP I

Pursuant to Section 242 of the
Delaware General Corporation Law

ANZU SPECIAL ACQUISITION CORP I (the “Corporation”), a corporation organized and existing under the laws of the State of Delaware, does hereby certify as follows:

(b) Immediately after the Offering, a certain amount of the net offering proceeds received by the Corporation in the Offering (including the proceeds of any exercise of the underwriter’s over-allotment option) and certain other amounts specified in the Corporation’s registration statement on Form S-1, as initially filed with the U.S. Securities and Exchange Commission (the “SEC”) on February 8, 2021, as amended (the “Registration Statement”), shall be deposited in a trust account (the “Trust Account”), established for the benefit of the Public Stockholders (as defined below) pursuant to a trust agreement described in the Registration Statement. Except for the withdrawal of interest to pay taxes, none of the funds held in the Trust Account (including the interest earned on the funds held in the Trust Account) will be released from the Trust Account until the earliest of (i) the completion of the initial Business Combination, (ii) the redemption of Offering Shares (as defined below) in connection with a vote seeking to amend any provisions of this Amended and Restated Certificate (A) to modify the substance or timing of the Corporation’s obligation to allow redemptions in connection with the Corporation’s initial Business Combination or to redeem 100% of the Offering Shares if the Corporation has not consummated an initial Business Combination by September 30, 2023 or such earlier date as determined by the Board or (B) with respect to any other provision relating to stockholders’ rights or pre-initial Business Combination activity (as described in Section 9.7) and (iii) the redemption of Offering Shares if the Corporation has not consummated an initial Business Combination by September 30, 2023 or such earlier date as determined by the Board. Holders of shares of the Common Stock included as part of the units sold in the Offering (the “Offering Shares”) (whether such Offering Shares were purchased in the Offering or in the secondary market following the Offering and whether or not such holders are Anzu SPAC GP I LLC (the “Sponsor”) or officers or directors of the Corporation, or affiliates of any of the foregoing) are referred to herein as “Public Stockholders.”

(d) In the event that the Corporation has not consummated an initial Business Combination by September 30, 2023 or such earlier date as determined by the Board, the Corporation shall (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter subject to lawfully available funds therefor, redeem 100% of the Offering Shares in consideration of a per share price, payable in cash, equal to the quotient obtained by dividing (A) the aggregate amount then on deposit in the Trust Account, including interest (less up to $100,000 of interest to pay dissolution expenses and which interest shall be net of taxes payable), by (B) the total number of then outstanding Offering Shares, which redemption will completely extinguish rights of the Public Stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining stockholders and the Board in accordance with applicable law, dissolve and liquidate, subject in each case to the Corporation’s obligations under the DGCL to provide for claims of creditors and other requirements of applicable law.

Additional Redemption Rights.   If, in accordance with Section 9.1(a), any amendment is made to this Amended and Restated Certificate to modify the substance or timing of the Corporation’s obligation to provide for the redemption of the Offering Shares in connection with an initial Business Combination or to redeem 100% of the Offering Shares if the Corporation has not consummated an initial Business Combination by September 30, 2023 or such earlier date as determined by the Board, or with respect to any other provision of this Amended and Restated Certificate relating to stockholder’s rights or pre-initial Business Combination activity, the Public Stockholders shall be provided with the opportunity to redeem their Offering Shares upon the approval of any such amendment, at a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable), divided by the number of then outstanding Offering Shares. The Corporation’s ability to provide such opportunity is subject to the Redemption Limitation.

IN WITNESS WHEREOF, Anzu Special Acquisition Corp I has caused this Amendment to its Amended and Restated Certificate of Incorporation to be duly executed in its name and on its behalf by an authorized officer as of this 28^th day of February, 2023.
