Form of Performance-Based Restricted Stock Unit Award Agreement, dated as of February 27, 2024

THIS AGREEMENT (the “Agreement”) is effective as of [●] (the “Grant Date”), by and between Gulfport Energy Corporation, a Delaware corporation (the “Company”), and [●] (the “Grantee”).

The Company has adopted the Gulfport Energy Corporation 2021 Stock Incentive Plan (as amended, modified or supplemented from time to time, the “Plan”), by this reference made a part hereof, for the benefit of eligible employees and consultants of the Company and its Related Companies, and members of the Board of Directors of the Company. Capitalized terms used and not otherwise defined herein shall have the meaning ascribed thereto in the Plan.

Pursuant to the Plan, the Committee, which has generally been assigned responsibility for administering the Plan, has determined that it would be in the interest of the Company and its stockholders to grant the performance-based Restricted Stock Units provided herein in order to provide the Grantee with the potential to earn additional remuneration for services rendered, to encourage the Grantee to remain in the employ of the Company or its Related Companies and to increase the Grantee’s personal interest in the continued success and progress of the Company.

The Company and the Grantee therefore agree as follows:

1.Grant of PSUs. Pursuant to the Plan and subject further to the terms and conditions herein, the Company and the Grantee enter into this Agreement pursuant to which the Company grants to Grantee a target of [●] performance-based Restricted Stock Units (the “Target Award”), where each such performance-based Restricted Stock Unit represents the right to receive one share of Common Stock or the cash equivalent thereof (the “PSUs”).

2.Vesting of PSUs.

a.General. The PSUs shall vest, if at all, following the close of the three (3)-year period beginning on January 1, 2024 and ending on December 31, 2026 (the “Performance Period”) based upon (i) the TSR (as defined below) of the Company, and (ii) the TSR of the Company relative to the TSR of the Peer Companies (as defined below) for the Performance Period (collectively, the “Performance Conditions”), subject to the Grantee’s continuous employment or service with the Company or any Related Company through the date of settlement pursuant to Section 3 hereof. The range of PSUs which may vest shall depend on the extent to which the Performance Conditions are satisfied, and shall range from zero percent (0%) to two-hundred percent (200%) of the Target Award. In no event will Grantee be deemed to be vested in or otherwise earn a number of PSUs with an aggregate value in excess of the lesser of (i) two-hundred percent (200%) of the Target Award, or (ii) an amount equal to five (5) times the (x) Fair Market Value of the Common Stock as of the the first day of the Performance Period, times (y) the Target Award. The number of PSUs that will vest during the Performance

Period shall be determined following the Committee’s certification of achievement of the Performance Conditions, which shall occur as soon as practicable following the end of the Performance Period, but in a manner such that the Company can satisfy the settlement deadline set forth in Section 3. For the avoidance of doubt, if the level of achievement of the Performance Conditions results in zero percent (0%) of the Target Award to be deemed vested, subject to Section 2(b), all PSUs awarded under this Agreement shall be forfeited and cancelled for no consideration therefor.

b.Performance Conditions.

i.Total shareholder return (“TSR”) for a company, including the Company, will be the result of the volume-weighted average price per share of the company for the thirty (30) calendar days ending on the last calendar day of the Performance Period (or such earlier date and using the applicable closing price instead of a thirty (30) day average as prescribed pursuant to Section 4(a)(ii), if applicable), minus the volume-weighted average price per share of the company for the first thirty (30) calendar days of the Performance Period (the “Reference Value”), plus dividends (cash or stock based on ex-dividend date) paid per share of common stock during the Performance Period calculated on a deemed reinvested basis, divided by the Reference Value and expressed as an annual compounded percentage rate of return over the Performance Period. The Reference Value will be adjusted accordingly in the event of a stock split. For the sake of clarity, with respect to any Change in Control or Special CiC Event that occurs prior to the end of the Performance Period, achievement of the Performance Conditions shall be measured on an annualized basis as if the Change in Control or Special CiC Event was the last day of the Performance Period, as more fully described in Section 4(a)(ii).

ii.“Peer Companies” means the companies listed on Schedule A, which may be adjusted during the Performance Period by the Committee in response to changes caused by corporate transactions, as described below. No companies may be added to the Peer Companies for the Performance Period. Any Peer Company that files for bankruptcy during the Performance Period will remain in the peer group and will be deemed to have a TSR of negative one-hundred percent (-100%) for purposes of determining the relative TSR ranking as described below. Any of the Peer Companies that is acquired by a third-party entity outside of the peer group during the Performance Period will remain in the peer group and will be deemed to have a TSR calculated based on the volume-weighted average price per share of the company for the thirty (30) calendar days ending on the closing date of such transaction and annualized for the remainder of the Performance Period.

iii.Following the close of the Performance Period, the Peer Companies and the Company shall be ranked together based on their TSR for the Performance Period from the highest TSR being number 1 to the lowest TSR

being the number of Peer Companies, including the Company. Based on the Company’s TSR and the Company’s relative TSR rank among the Peer Companies for the Performance Period, the percentage of the Target Award that will be deemed vested shall be determined in accordance with the following grid:

Fractional shares will be rounded up to the next whole number.

3.Settlement of PSUs. Any PSUs that vest pursuant to Section 2 hereof (or any termination of employment or service or other vesting date as described in Section 4 hereof) shall be settled as soon as practicable following the last day of the Performance Period (or applicable vesting date pursuant to Section 4), but in no event later than thirty (30) days (or such shorter time period specified pursuant to Section 4) following the end of the Performance Period (or applicable vesting date pursuant to Section 4). Upon such settlement the Company shall deliver to the Grantee (i) certificates representing the applicable number shares of Common Stock or cause the applicable number of shares of Common Stock to be evidenced in book-entry form in the Grantee’s name in the stock register of the Company maintained by the Company’s transfer agent, (ii) cash equal to the Fair Market Value of the applicable number of shares of Common Stock on such date, or (iii) any combination of (i) and (ii).

4.Termination of Employment or Service. Subject to Section 4(a) below, if the Grantee ceases employment or service to the Company or the applicable Related Company for any reason prior to the end of the Performance Period, the PSUs will be immediately forfeited and cancelled, and the Grantee will thereupon cease to have any right or entitlement to receive any shares of Common Stock under this Agreement.

i.upon a termination of the Grantee’s employment or service with the Company or applicable Related Company (x) due to death or Disability prior to the end of the Performance Period, or (y) by the Company or applicable Related Company without Cause or due to a resignation by Grantee for Good Reason within the last eighteen (18) months of the Performance Period, a pro-rata portion of the PSUs shall vest (based on the number of days of employment or service actually served during the Performance Period compared to the total number of days in the Performance Period), based on the actual achievement of

the Performance Conditions to be determined at the expiration of the Performance Period (or, if earlier, upon a subsequent Change in Control), and shall be settled pursuant to Section 3 hereof, and any remaining unvested PSUs shall be immediately forfeited and cancelled, and the Grantee will thereupon cease to have any right or entitlement to receive any shares of Common Stock under this Agreement; provided, that if Grantee is terminated by the Company or applicable Related Company without Cause or resigns for Good Reason within the first eighteen (18) months of the Performance Period, the Committee shall have sole discretion to determine whether the PSUs shall accelerate and vest in such manner. For purposes of this Agreement, “Good Reason” shall mean (x) with respect to any Grantee who is a party to a written employment agreement between the Grantee and the Company or any Related Company (an “Employment Agreement”) and which Employment Agreement provides for a definition of Good Reason, as defined therein, and (y) with respect to all other Grantees, the occurrence of one of the following events: (A) elimination of Grantee’s job position or material reduction in duties and/or reassignment of Grantee to a new position of materially less authority; (B) a material reduction in Grantee’s base salary, other than a general reduction in base salary that affects all similarly situated employees in substantially the same proportions; or (C) a requirement that Grantee relocate to a location outside of a fifty (50) mile radius of the location of his or her office or principal base of operation as of the Grant Date. Notwithstanding the foregoing, Grantee will not be deemed to have terminated for Good Reason unless (1) Grantee provides written notice to the Company of the existence of one of the conditions described above within ninety (90) days after Grantee has knowledge of the initial existence of the condition, (2) the Company fails to remedy the condition so identified within thirty (30) days after receipt of such notice (if capable of correction), (3) Grantee provides a notice of termination to the Company within thirty (30) days of the expiration of the Company’s period to remedy the condition specifying an effective date for Grantee’s termination, and (4) the effective date of Grantee’s termination of employment is within ninety (90) days after Grantee provides written notice to the Company of the existence of the condition referred to in clause (1); or

ii.upon the occurrence of a Change in Control during the Performance Period, (x) to the extent the PSUs are not assumed by the surviving entity in connection with such Change in Control, Grantee will become vested in one-hundred percent (100%) of the Target Award or, if greater, the percentage of the Target Award earned based on the actual achievement of the Performance Conditions to be determined as if the Change in Control was the last day of the Performance Period, except that the TSR for the Company and each of the Peer Companies will be determined using the closing price as of the closing date of the Change in Control compared to the Reference Value, rather than the thirty (30)-day average prescribed pursuant to Section 2(b)(i), and the PSUs shall be settled as soon as practicable following the date of the Change in Control, but in no event later than ten (10) days following the Change in Control; and (y) to the extent the

PSUs are assumed by the surviving entity in connection with such Change in Control, the PSUs shall be converted, as of the date of such Change in Control, into time-based Restricted Stock Units (the “Converted RSUs”), subject to the Grantee’s continuous employment or service with the Company or any Related Company through the date of such Change in Control, with the number of PSUs to be converted equal to one-hundred percent (100%) of the Target Award or, if greater, the percentage of the Target Award earned based on the actual achievement of the Performance Conditions to be determined as if the Change in Control was the last day of the Performance Period, except that the TSR for the Company and each of the Peer Companies will be determined using the closing price as of the closing date of the Change in Control compared to the Reference Value, rather than the thirty (30)-day average prescribed pursuant to Section 2(b)(i), and one-hundred percent (100%) of the Converted RSUs shall vest, if at all, on the last day of the Performance Period, subject to the Grantee’s continuous employment or service with the surviving entity through such date; provided, that if Grantee’s employment or service is terminated due to death or Disability, by the Company or a Related Company without Cause or due to a resignation by Grantee for Good Reason following such Change in Control, one-hundred percent (100%) of the Converted RSUs shall vest as of the date of such termination and be settled pursuant to Section 3 hereof. Notwithstanding the foregoing, in the event of (A) a change in the composition of the Board such that, for a period of thirty (30) days, the majority of the members of the Board (x) are no longer considered “independent” under the applicable listing standards or rules of the securities exchange upon which the Common Stock is traded, or (y) have a financial relationship with, or are otherwise not independent of, any Person that beneficially owns stock representing more than thirty-five percent (35%) of the total combined voting power of all classes of stock of the Company, or (B) the consummation of any transaction resulting in any Person who was a stockholder of the Company prior to such transaction becoming the Beneficial Owner, directly or indirectly, of more than seventy-five percent (75%) of the total combined voting power of all classes of stock of the Company (either such event, a “Special CiC Event”), Grantee will become vested in one-hundred percent (100%) of the Target Award or, if greater, the percentage of the Target Award earned based on the actual achievement of the Performance Conditions to be determined as of the Special CiC Event (determined as if the Special CiC Event was the last day of the Performance Period), and shall be settled as soon as practicable following the date of the Special CiC Event, but in no event later than ten (10) days following the Special CiC Event.

5.No Ownership Rights Prior to Issuance of Shares of Common Stock; Dividend Equivalents.

a.Neither the Grantee nor any other person shall become the beneficial owner of the shares of Common Stock underlying the PSUs, nor have any rights of a shareholder (including, without limitation, dividend and voting rights) with respect to any

such shares of Common Stock, unless and until and after such shares of Common Stock have been settled and delivered to the Grantee pursuant to Section 3 hereof.

b.Notwithstanding the foregoing, if, after the Grant Date and prior to the distribution or payment in settlement of the PSUs, dividends with respect to the shares of Common Stock underlying the PSUs are declared or paid by the Company, Grantee shall be entitled to receive the equivalent value (in cash or shares of Common Stock) of any such dividends paid on such shares of Common Stock (“Dividend Equivalents”) in an amount, without interest, equal to the cumulative dividends declared or paid on a share of Common Stock, if any, during such period multiplied by the number of PSUs that vest. Dividend Equivalents will be subject to the same terms and conditions of this Agreement applicable the PSUs. The Dividend Equivalents will be paid on the applicable date of distribution or payment in settlement of the underlying PSUs in cash or shares of Common Stock, as determined by the Committee in its discretion.
