2025 EQUITY AND INCENTIVE PLAN

RESTRICTED STOCK UNIT AWARD AGREEMENT

Flowco Holdings Inc., a corporation organized under the laws of the State of Delaware (the “Company”), hereby grants to the individual (the “Holder”) named in the award notice attached hereto (the “Award Notice”) as of the date set forth in the Award Notice (the “Grant Date”), pursuant to the provisions of the Flowco Holdings Inc. 2025 Equity and Incentive Plan (the “Plan”), a Restricted Stock Unit Award (this “Award”) with respect to the number of shares of the Company’s Class A Common Stock, par value $0.0001 per share (“Common Stock”), set forth in the Award Notice (such shares of Common Stock, the “Shares”), upon and subject to the restrictions, terms and conditions set forth in the Plan and this Restricted Stock Unit Award Agreement (the “Agreement”). Capitalized terms not defined herein shall have the meanings specified in the Plan.

1. Award Subject to Acceptance of Agreement. The Award shall be null and void unless the Holder accepts this Agreement by executing the Award Notice in the space provided therefor and returning an original execution copy of the Award Notice to the Company or, if applicable, electronically accepting this Agreement within the Holder’s stock plan account with the Company’s stock plan administrator according to the procedures then in effect.

2. Rights as a Stockholder; Dividends. The Holder shall not be entitled to any rights and privileges of ownership with respect to the Shares subject to the Award unless and until, and only to the extent, such Shares become vested pursuant to Section 3 hereof and the Holder becomes a stockholder of record with respect to such Shares. As of each date on which the Company pays a cash dividend to record owners of Shares (a “Dividend Date”), the Holder shall have no entitlement to receive such cash dividend, and the number of Shares subject to the Award shall increase by (i) the product of the total number of Shares subject to the Award immediately prior to such Dividend Date multiplied by the dollar amount of the cash dividend paid per Share by the Company on such Dividend Date, divided by (ii) the Fair Market Value of a Share on such Dividend Date. Any such additional Shares shall be subject to the same vesting conditions and payment terms set forth herein as the Shares to which they relate. The Award includes a right to dividend equivalents equal to the value of any dividends paid on the Common Stock for which the dividend record date occurs between the Grant Date and the date the Award is settled or forfeited. Subject to vesting, each dividend equivalent entitles the Holder to receive the equivalent cash value of any such dividends paid on the number of Shares underlying the Award that are outstanding during such period. Dividend equivalents will be accrued (without interest) and will be subject to the same conditions as the Shares to which they are attributable, including, without limitation, the vesting conditions, the provisions governing the time and form of settlement of the Award.

3. Restriction Period, Vesting and Forfeiture.

3.1. Service-Based Vesting Condition. Except as otherwise provided in this Section 3, the Award shall vest in accordance with the vesting schedule set forth in the Award Notice. The period of time prior to the full vesting of the Award is referred to herein as the “Restriction Period.”

3.2. Termination of Employment Without Cause. If the Holder’s employment with the Company and/or a Subsidiary is terminated by the Company and/or a Subsidiary without Cause prior to the end of the Restriction Period and prior to a Change in Control, then the Award shall vest in its entirety and be settled within 60 days following the Holder’s termination of employment, subject to the Holder’s execution and non-revocation of a release of claims in the form prescribed by the Company and which shall be delivered and returned to the Company during the period specified in the release (but in any event no later than 52 days following the Holder’s termination of employment).

3.3. Termination of Employment for Any Other Reason. If the Holder’s employment with the Company and/or a Subsidiary terminates, and Holder otherwise ceases to serve as a Non-Employee Director or provide services to the Company and/or a Subsidiary as a consultant or advisor, prior to the end of the Restriction Period and prior to a Change in Control for any reason other than by the Company without Cause, then the Award shall be immediately and automatically forfeited by the Holder and cancelled by the Company for no consideration.

6. Additional Terms and Conditions of Award.

6.1. Withholding Taxes. (a) As a condition precedent to the delivery to the Holder of any shares of Stock upon vesting of the Award, the Holder shall, upon request by the Company, pay to the Company such amount of cash as the Company is required (in the reasonable, good faith determination of the Company), under all applicable federal, state, local or other laws or regulations, to withhold and pay over as income or other withholding taxes (or such higher withholding amount elected by the Holder) (the “Required Tax Payments”) with respect to the Award. If the Holder shall fail to advance the Required Tax Payments after request by the Company, the Company may, in its discretion, deduct any Required Tax Payments from any amount then or thereafter payable by the Company to the Holder or withhold shares of Stock.

(b) The Holder may elect to satisfy his or her obligation to advance the Required Tax Payments by any of the following means: (1) a cash payment to the Company; (2) delivery to the Company (either actual delivery or by attestation procedures established by the Company) of previously owned whole shares of Stock having a Fair Market Value, determined as of the date the obligation to withhold or pay taxes first arises in connection with the Award (the “Tax Date”), equal to the Required Tax Payments; (3) authorizing the Company to withhold from the shares of Stock otherwise to be delivered to the Holder pursuant to the Award, a number of whole shares having a Fair Market Value, determined as of the Tax Date, equal to the Required Tax Payments; or (4) any combination of (1), (2) and (3). Shares to be delivered or withheld may not have a Fair Market Value in excess of the minimum amount of the Required Tax Payments (or, if approved by the Committee, such higher rate that will not cause adverse accounting consequences). Any fraction of a share which would be required to satisfy such an obligation shall be disregarded and the remaining amount due shall be paid in cash by the Holder. No shares of Stock shall be delivered until the Required Tax Payments have been satisfied in full.

6.2. Compliance with Applicable Law. The Award is subject to the condition that if the listing, registration or qualification of the shares of Stock subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the delivery of shares hereunder, the shares of Stock subject to the Award shall not be delivered, in whole or in part, unless such listing, registration, qualification, consent, approval or other action shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent, approval or other action.

6.3. Award Confers No Rights to Continued Employment or Service. In no event shall the granting of the Award or its acceptance by the Holder, or any provision of the Agreement or the Plan, give or be deemed to give the Holder any right to continued employment by or service with the Company, any Subsidiary or any affiliate of the Company or affect in any manner the right of the Company, any Subsidiary or any affiliate of the Company to terminate the employment or service of any person at any time.

6.4. Decisions of Board or Committee. The Board or the Committee shall have the right to resolve all questions which may arise in connection with the Award. Any interpretation, determination or other action made or taken by the Board or the Committee regarding the Plan or this Agreement shall be final, binding and conclusive.

In the event that the provisions of this Agreement and the Plan conflict, the Plan shall control. The Holder hereby acknowledges receipt of a copy of the Plan.

6.9. Entire Agreement. This Agreement and the Plan constitute the entire agreement of the parties with respect to the subject matter hereof and supersede in their entirety all prior undertakings and agreements of the Company and the Holder with respect to the subject matter hereof, and may not be modified adversely to the Holder’s interest except by means of a writing signed by the Company and the Holder.

This Award is intended to be exempt from or comply with Section 409A of the Code, and shall be interpreted and construed accordingly, and each payment hereunder shall be considered a separate payment for purposes of Section 409A of the Code. To the extent this Agreement provides for the Award to become vested and be settled upon the Holder’s termination of employment, the applicable shares of Stock shall be transferred to the Holder or his or her beneficiary upon the Holder’s “separation from service,” within the meaning of Section 409A of the Code; provided that if the Holder is a “specified employee,” within the meaning of Section 409A of the Code, then to the extent the Award constitutes nonqualified deferred compensation, within the meaning of Section 409A of the Code, such shares of Stock shall be transferred to the Holder or his or her beneficiary upon the earlier to occur of (i) the six-month anniversary of such separation from service and (ii) the date of the Holder’s death.

6.14. Award Subject to Clawback.
