RESTRICTED STOCK UNIT AGREEMENT

Exhibit 10.9

RESTRICTED STOCK UNIT AGREEMENT

Biora Therapeutics, Inc. (the “Company”) has granted to the Participant named in the Notice of Grant of Restricted Stock Units (the “Grant Notice”) to which this Restricted Stock Unit Agreement (this “RSU Agreement”) is attached a Restricted Stock Unit Award to acquire a certain number of shares of Common Stock upon the vesting and settlement of such award as set forth in the Grant Notice and this RSU Agreement (the “RSU Award”). The RSU Award has been granted pursuant to and shall in all respects be subject to the terms and conditions of the Biora Therapeutics, Inc. 2021 Inducement Plan (the “Plan”), the provisions of which are incorporated herein by reference. By accepting the grant, the Participant: (a) acknowledges receipt of, and represents that the Participant has read and is familiar with the terms and conditions of, the Grant Notice, this RSU Agreement and the Plan, (b) acknowledges and agrees to all of the terms and conditions of the RSU Award as set forth in the Grant Notice, this RSU Agreement and the Plan, and (c) agrees to accept as binding, conclusive and final all decisions or interpretations of the Board upon any questions arising under the Grant Notice, this RSU Agreement or the Plan.

1.DEFINITIONS AND CONSTRUCTION.

1.1Definitions. Unless otherwise defined herein, capitalized terms shall have the meanings assigned to such terms in the Grant Notice or the Plan.

1.2Construction. Captions and titles contained herein are for convenience only and shall not affect the meaning or interpretation of any provision of this RSU Agreement. Except when otherwise indicated by the context, the singular shall include the plural and the plural shall include the singular. Use of the term “or” is not intended to be exclusive, unless the context clearly requires otherwise.

2.Inducement Award. This RSU Award is granted to Participant as a material inducement to the commencement of employment within the meaning of the Listing Rule.

3.VESTING AND SETTLEMENT OF THE RSU AWARD.

3.1General. The RSU Award shall vest in accordance with the vesting schedule set forth in the Grant Notice. In the event that the vesting schedule applicable to the RSU Award results in the vesting of a fractional share of Common Stock, the vesting shall be rounded down to the nearest whole share of Common Stock, except at the time that Participant becomes fully vested in the RSU Award, the Participant shall become vested in all remaining unvested shares of Common Stock subject to the RSU Award. Each Restricted Stock Unit represents the right to receive payment on the date it vests in the form of one share of the Company’s Common Stock. In no event shall the Participant receive such shares in respected of vested Restricted Stock Units any later than March 15th of the year subsequent to the year of vesting. Prior to actual payment of a share of Common Stock on any vested Restricted Stock Unit, such Restricted Stock Unit will represent an unsecured obligation of the Company, for which there is no trust and no obligation other than to issue shares of Common Stock as contemplated by this RSU Agreement and the Plan.

3.2Change in Control. Upon a Change in Control that occurs while any portion of the RSU Award remains unvested, the RSU Award shall be assumed or an equivalent award substituted by the successor corporation (or a parent thereof) (the “Acquiror”) and such award shall continue to be subject to the same vesting terms provided under the Grant Notice and this Agreement; provided, that the Participant shall be eligible to receive 100% of the shares of Common Stock then subject to the RSU Award if the Acquiror does not either assume the RSU Award or substitute an equivalent award for the RSU Award and the Board does not take other action provided for under Section 9(c) of the Plan.

3.3Tax Withholding. The Company may, in its sole discretion, satisfy any U.S. federal, state, local, foreign or other tax withholding obligation relating to the vesting, settlement or any other event that triggers a tax liability with respect to the RSU Award by any of the following means or by a combination of such means: (a) causing the Participant to tender, or cause to have tendered, a cash payment, (b) withholding from the Participant’s cash compensation from the Company after obtaining the authorization of the Participant, (c) withholding, or causing to have withheld, shares of Common Stock or other securities or other property from the shares of Common Stock, other securities or other property issued or otherwise issuable to the Participant in connection with the settlement of the RSU Award (only up to the amount permitted that will not cause an adverse accounting consequence or cost), or (d) payment from any amounts otherwise payable to the Participant out of proceeds from the sale of shares of Common Stock issued pursuant to the RSU Award under a program established by the Company. Unless otherwise provided by

the Company through action of the Board or Committee or agreement with the Participant, the Company’s withholding tax obligations shall generally be satisfied using the approach set forth under (c) or (d) above. None of the Company, its Affiliates, its representatives or agents, or any other person shall have any obligation to deliver shares of Common Stock or other securities or other property, until the tax withholding obligations of the Company have been fully satisfied by the Participant.

3.4Beneficial Ownership of Shares; Certificate Registration. The Participant hereby authorizes the Company, in its sole discretion, to deposit for the benefit of the Participant with any broker selected by the Company, or with the concurrence of the Company, any broker with which the Participant has an account relationship of which the Company has notice, any or all shares of Common Stock acquired by the Participant pursuant to the settlement of the RSU Award. Except as provided by the preceding sentence, a certificate for the shares as to which the RSU Award is settled shall be registered in the name of the Participant, or, if applicable, in the names of the heirs of the Participant (or for any uncertificated shares, such entry shall be made in book-entry form).

3.5Fractional Shares. The Company shall not be required to issue fractional shares of Common Stock upon the settlement of the RSU Award.

3.6No Rights as a Stockholder; Spin-Off Participation.

(a)The Participant shall not be deemed to be the holder of, or to have any of the rights of a holder with respect to, any share of Common Stock subject to the RSU Award, including but not limited to voting rights and rights to dividends and distributions that may become payable to the holders of Common Stock, prior to the time that (i) all vesting conditions set forth in the Grant Notice and this RSU Agreement have been satisfied (i.e., satisfaction of the required period of Continuous Service), (ii) such share of Common Stock has been issued by the Company, and (iii) such issuance of the share of Common Stock subject to the RSU Award has been entered into the books and records of the Company, unless expressly provided herein. Except as provided in Section 3.6(b) below, no dividends, distributions or dividend equivalents shall be credited in respect of shares of Common Stock covered by the RSU Award until the time that such shares of Common Stock have been issued and such issuance has been entered into the books and records of the Company.

(b)In the event that the holders of shares of Common Stock receive as a dividend securities of a subsidiary of the Company (such entity, “SpinCo”) in a spin-off of all or substantially all of the equity securities of SpinCo held directly or indirectly by the Company (a “Spin-Off”), then the Participant shall be eligible to receive a number of shares of restricted common stock of SpinCo equal to (i) the number of shares of Common Stock subject to the portion of the RSU Award that has vested based on Continuous Service as of the effective date of the Spin- Off, multiplied by (ii) the number of securities of SpinCo that a holder of one share of Common Stock will receives in the Spin-Off (such restricted common stock of SpinCo, the “SpinCo Restricted Shares”). None of the Company, SpinCo or any other person shall have any obligation to settle the SpinCo Restricted Shares until the tax withholding obligations of the Company and/or SpinCo have been satisfied by the Participant. Notwithstanding the foregoing, the Company may, in its sole discretion, determine to provide, or cause to have provided, other equity securities or derivative securities of SpinCo of equivalent value (as determined by the Board) in lieu of the SpinCo Restricted Shares at the time of the Spin-Off. If the Company so determines, references in this RSU Agreement to SpinCo Restricted Shares shall mean such other equity securities or derivative securities of SpinCo.

4.EFFECT OF TERMINATION OF CONTINUOUS SERVICE.

4.1The following terms shall govern the treatment of the RSU Award upon the

Participant’s termination of Continuous Service:

(a)Termination for Cause. Notwithstanding any other provision of this RSU Agreement, if the Participant’s Continuous Service is terminated for Cause, the RSU Award shall terminate in its entirety upon such termination of Service.

(b)Other Termination of Service. If the Participant’s Continuous Service terminates for any reason (other than for Cause), the Participant shall be eligible to receive the shares of Common Stock subject to the portion of the RSU Award that has vested based on Continuous Service as of the date on which the Participant’s Continuous Service terminates. The portion of the RSU Award that remains unvested as of the date on which the Participant’s Continuous Service terminates, shall be forfeited and become null and void.

5.PROHIBITION ON TRANSFER

The Participant shall not offer, sell, enter a contract to sell, pledge, hypothecate, grant any option to purchase or make any short sale of, or otherwise dispose of or transfer, or attempt to dispose of or transfer, the RSU Award (or any shares of Common Stock subject to the RSU Award) or any rights to acquire stock of the Company or any SpinCo under the RSU Award.
