PBAX Phoenix Biotech Aquisition Corporation

On December 16, 2022, Phoenix Biotech Acquisition Corp. (the “Company”) held a special meeting of stockholders (the “Special Meeting”) at 11:00 a.m. Eastern Time for the purposes of considering and voting upon the Charter Amendment Proposal, the Trust Amendment Proposal and, if presented, the Adjournment Proposal (each as defined below). For more information on these proposals, please refer to the Company’s definitive proxy statement filed with the Securities and Exchange Commission (the “SEC”) dated November 21, 2022 (the “Proxy Statement”).

Promissory Note

As previously disclosed in the Proxy Statement, Phoenix Biotech Sponsor, LLC (the “Sponsor”) agreed that if the Charter Amendment Proposal and the Trust Amendment Proposal (each as defined below) were approved at the Special Meeting, the Sponsor, or one or more of its affiliates, members or third-party designees (in such capacity, the “Lender”), would lend to the Company up to $1,500,000 to be deposited into the trust account (the “Trust Account”) established in connection with the Company’s initial public offering (the “IPO”).

On December 16, 2022, the stockholders of the Company approved the Charter Amendment Proposal and the Trust Amendment Proposal at the Special Meeting (as described in Item 5.07 of this Current Report on Form 8-K). Accordingly, on December 20, 2022, the Company issued an unsecured promissory note in the principal amount of $1,500,000 (the “Promissory Note”) to the Lender, pursuant to which the Lender agreed to loan to the Company up to $1,500,000 in connection with the extension of the date by which the Company has to consummate an initial business combination (the “business combination period”). The Promissory Note does not bear interest and matures upon the earlier of (a) the closing of an initial business combination and (b) the Company’s liquidation. In the event that the Company does not consummate an initial business combination, the Promissory Note will be repaid only from amounts remaining outside of the Trust Account, if any. Upon the consummation of an initial business combination, the Lender may elect to convert any portion or all of the amount outstanding under the Promissory Note into private placement units of the Company (each, a “Private Placement Unit”), each Private Placement Unit consisting of one share of the Company’s Class A common stock, par value $0.0001 per share (“Common Stock”), and one-half of one warrant to purchase one share of Common Stock. Such Private Placement Units will be identical to the private placement units issued to the Sponsor at the time of the IPO.

The Company has deposited $325,000 into the Trust Account in connection with the first drawdown under the Promissory Note in order to effect the extension of the business combination period to April 8, 2023 (the “Charter Extension Date”), and will deposit additional funds into the Trust Account for any subsequent extensions that are needed by the Company to complete an initial business combination. Such amounts will be distributed either to: (i) the holders of shares of Common Stock issued as part of the units sold in the IPO (the “Public Shares”) outstanding as of immediately prior to the Company’s liquidation or (ii) holders of Public Shares who elect to have their shares redeemed in connection with the consummation of an initial business combination.

The issuance of the Promissory Note was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended.

The foregoing description is qualified in its entirety by reference to the Promissory Note, a copy of which is attached as Exhibit 10.1 hereto and is incorporated herein by reference.

Trust Agreement Amendment

At the Special Meeting, the Company’s stockholders approved a proposal to amend (the “Trust Agreement Amendment”) the Investment Management Trust Agreement (the “Trust Agreement”), dated as of October 5, 2021, by and between the Company and Continental Stock Transfer and Trust Company (“Continental”), to extend the business combination period from January 8, 2023 to April 8, 2023 and up to three times for an additional one month each time from April 8, 2023 to May 8, 2023, June 8, 2023 or July 8, 2023. On December 20, 2022, the Company and Continental entered into the Trust Agreement Amendment.

The foregoing description of the Trust Agreement Amendment is a summary only and is qualified in its entirety by reference to the full text of the Trust Agreement Amendment, a copy of which is attached as Exhibit 10.2 hereto and is incorporated by reference herein.
