Form of Performance-Based, Stock-Settled Restricted Stock Unit Agreement

POST HOLDINGS, INC. (the “Company”), hereby grants to the individual named below (the “Grantee”) an award of performance-based restricted stock units (the “PRSUs”) as set forth below, effective on the Date of Grant set forth below, subject to the Grantee timely executing and delivering to the Company, pursuant to such procedures as the Company will establish from time to time, this PRSU Agreement (this “Agreement”). The PRSUs shall vest and become payable in Shares, subject to earlier termination of the PRSUs, as provided in this Agreement and the terms and conditions of the Post Holdings, Inc. 2019 Long-Term Incentive Plan (the “Plan”). Capitalized terms used but not defined in this Agreement shall have the same definitions as in the Plan.

1.Award. Each PRSU represents the right to receive one Share with respect to each PRSU that vests as set forth in this Agreement, including Appendix A, subject, as applicable, to achievement of the applicable Performance Criteria and certification by the Committee thereof (the portion of the PRSUs that vests is hereafter referred to as the “Vested Units”).

2.Vesting and Forfeiture.

(a)    Condition to Vesting. The vesting of the PRSUs on a Vesting Date (as defined in Section 2(b)) is, subject to the Grantee’s continued employment with the Company (or its Affiliates or Parent, as applicable) through the applicable Vesting Date, except as specifically provided by Section 2(b)(ii)(1).

(b)    Accelerated Vesting.

i.    Death and Disability. Subject to Section 2(c) below, the Target Award will become Vested Units as of the date of the Grantee’s death or Disability (such date, an “Accelerated Vesting Date” which, together with the Default Vesting Date, is a “Vesting Date”), if either such event occurs prior to the Default Vesting Date.

ii.    Change in Control. Subject to Section 2(c) below, notwithstanding anything to the contrary in Section 6(g) of the Plan, in the event the Grantee ceases to be employed with the Company, either as a result of a termination by the Company without Cause or by the Grantee for Good Reason:

1.    Within the three (3)-month period prior to the occurrence of a Change in Control Date or on the Change in Control Date, a number of unvested PRSUs shall become Vested Units on such Change in Control equal to the greater of: (A) the number of PRSUs that would have become vested based upon the achievement of the Performance Criteria, calculated as set forth in Appendix A through the last full trading day prior to the Change in Control Date (such date, also an “Accelerated Vesting Date”) or (B) the Target Award

adjusted pro-rata based on the number of days of the Performance Period which have passed as of the Change in Control Date (such date, also an “Accelerated Vesting Date”); or

2.    During the twelve (12)-month period starting on the day following the Change in Control Date and ending on the first anniversary of the Change in Control Date, a number of unvested PRSUs shall become Vested Units on such termination of employment equal to the greater of: (A) the number of PRSUs that would have become vested based upon the achievement of the Performance Criteria, calculated as set forth in Appendix A through the last full trading day prior to date upon which the Grantee ceases to be employed (such date, also an “Accelerated Vesting Date”) or (B) the Target Award adjusted pro-rata based on the number of days of the Performance Period which have passed as of the day of termination of employment (such date, also an “Accelerated Vesting Date”).

iii.    Failure to Assume. In the event that in connection with a Change in Control the acquirer does not agree to assume in writing, effective upon the Change in Control, on substantially the same terms, the PRSUs and the obligations hereunder: a number of unvested PRSUs shall become Vested Units as of immediately prior to the Change in Control Date equal to the number of PRSUs that would have become vested based upon the achievement of the Performance Criteria, calculated as set forth in Appendix A through the last full trading day prior to the Change in Control Date (such date, also an “Accelerated Vesting Date”), and the remainder shall be forfeited.

(c)    Conversion to Time-Based Awards. If the Committee determines that, as the result of the occurrence of a Change in Control, the Performance Criteria should no longer apply to the PRSUs following the Change in Control, the Committee shall calculate the Vesting Percentage as set forth in Appendix A through the last full trading day prior to the Change in Control Date and thereafter a number of PRSUs equal to the Target Award multiplied by such Vesting Percentage (the “Time-Based PRSUs”) will be subject to the requirement to remain employed through the applicable Vesting Date (and except for such Time-Based PRSUs, any other portion of the award made pursuant to this Agreement shall be forfeited without payment or consideration therefor), it being understood that (i) the applicable Vesting Date of the then-outstanding Time-Based PRSUs shall be either the Default Vesting Date set forth above or, if applicable, an Accelerated Vesting Date, subject to the conditions thereof, (ii) upon such applicable Vesting Date, if any, the Time-Based PRSUs shall become vested without additional adjustment with respect to performance through such applicable Vesting Date, and (iii) in the event the Grantee’s employment terminates prior to such applicable Vesting Date (other than a termination described in Section 2(b) above, in which case the then-outstanding Time-Based PRSUs shall become vested pursuant to clause (ii) of this Section 2(c)), the Time-Based PRSUs shall be forfeited as set forth in Section 2(d).

(d)    Forfeiture Upon Termination of Employment. Except as otherwise provided in Sections 2(b) and 2(c) above, in the event that the Grantee’s employment with the Company terminates for any reason or no reason, voluntarily or involuntarily, the Grantee shall forfeit any and all PRSUs which are not and cannot become, as of the time of such termination or as a result of the completion of the Performance Period, Vested Units, and the Grantee shall not be entitled to any payment or other consideration with respect thereto.

(e)    Definition of Cause. For purposes of this Agreement, Cause shall be defined as: (i) Grantee’s conviction of a crime, the circumstances of which involve fraud, embezzlement, misappropriation of funds, dishonesty or moral turpitude, and which is substantially related to the circumstances of Grantee’s duties; (ii) Grantee’s conviction of a crime, the circumstances of which involve federal or state securities laws; or (iii) Grantee’s falsification of Company or Affiliate records.

3.Settlement of the Vested Units.

(a)    Settlement. Subject to all the terms and conditions set forth in this Agreement and the Plan, the Company shall issue to the Grantee a number of Shares equal to the number of Vested Units no later than sixty (60) days after the Vesting Date.

(b)    Compliance with Laws. The grant of the PRSUs and issuance of Shares upon settlement of the Vested Units shall be subject to and in compliance with all applicable requirements of federal, state and foreign law with respect to such securities, other law or regulations and the requirements of any stock exchange or market system upon which the Stock may then be listed. The Company’s inability to obtain permission or other authorization from any relevant regulatory body necessary to the lawful issuance of any Shares subject to the Vested Units shall relieve the Company of any liability in respect of the failure to issue such Shares as to which such requisite authority was not obtained. As a condition to the settlement of the Vested Units, the Company may require the Grantee to satisfy any qualifications that may be necessary or appropriate, to evidence compliance with any applicable law or regulation and/or to make any representation or warranty with respect thereto.

(c)    Registration. Shares issued in settlement of the Vested Units shall be registered in the name of the Grantee. Such Shares may be issued either in certificated or book entry form. In either event, the certificate or book entry account shall bear such restrictive legends or restrictions as the Company, in its sole discretion, shall require.

4.Incorporation of the Plan by Reference. The award of PRSUs pursuant to this Agreement is granted under, and expressly subject to, the terms and provisions of the Plan, which terms and provisions are incorporated herein by reference, except as expressly provided herein. The Grantee hereby acknowledges that a copy of the Plan has been made and remains available to the Grantee.

5.Committee Discretion. This Award has been made pursuant to a determination made by the Committee. Notwithstanding anything to the contrary herein, the Committee shall have the authority as set forth in the Plan.

6.No Right to Continued Employment. Nothing in this Agreement shall be deemed to create any limitation or restriction on such rights as the Company or its Affiliates or Parent otherwise would have to terminate the employment of the Grantee at any time for any reason.

7.Withholding of Taxes. In addition to any rights the Company may have pursuant to Section 13(d) of the Plan, the Company shall make such provisions for the withholding or payment of taxes as it deems necessary under applicable law and shall have the right to deduct from payments of any kind otherwise due to the Grantee or alternatively to require the Grantee to remit to the Company an amount in cash, by wire transfer of immediately available funds, certified check or such other form as may be acceptable to the Company, sufficient to satisfy at the time when due any federal, state, or local taxes or other withholdings of any kind required by law to be withheld with respect to the PRSUs.

9.Governing Law. To the extent federal law does not otherwise control, this Agreement shall be governed by the laws of the State of Missouri, without giving effect to principles of conflicts of laws. The Grantee shall be solely responsible to seek advice as to the laws of any jurisdiction to which he or she may be subject, and participation by the Grantee in the Plan shall be on the basis of a warranty by the Grantee that he or she may lawfully so participate without the Company being in breach of the laws of any such jurisdiction.

10.Not Assignable or Transferable. The PRSUs shall not be assignable or transferable other than by will or by the laws of descent and distribution.

In the event of any such assignment, such trust or custodianship shall be subject to all the restrictions, obligations, and responsibilities as apply to the Grantee under the Plan and this Agreement and shall be entitled to all the rights of the Grantee under the Plan.

11.Specified Employee Delay and Separation.
