The First Amendment amended the Credit Agreement to require the Operating Partnership to maintain, among other things:

•a minimum Interest Coverage Ratio (as defined in the Credit Agreement) of at least 2.00:1.00 for the fiscal quarter ended December 31, 2024, stepping down to 1.75:1.00 for the fiscal quarters ending March 31, 2025, June 30, 2025 and September 30, 2025, and stepping back up to 2.00:1.00 for the fiscal quarter ending December 31, 2025 and each fiscal quarter thereafter; and

•a maximum First Lien Leverage Ratio (as defined in the Credit Agreement) of not more than 1.50:1.00 for the fiscal quarter ended December 31, 2024, stepping down to 1.25:1.00 for the fiscal quarters ending March 31, 2025, June 30, 2025 and September 30, 2025, and stepping back up to 1.50:1.00 for the fiscal quarter ending December 31, 2025 and each fiscal quarter thereafter.

The foregoing description of the First Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the First Amendment, a copy of which is filed herewith as Exhibit 10.1 and is incorporated herein by reference.

Item 2.03 Creation of a Direct Financial Obligation or an Obligation Under an Off-Balance Sheet Arrangement of a Registrant.

The information set forth above in Item 1.01 regarding the First Amendment is incorporated by reference into this Item 2.03.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On February 11, 2025, the board of directors and the compensation committee of the board of directors of Martin Midstream GP LLC, the general partner of the Partnership, approved the Martin Midstream Partners L.P. 2025 Phantom Unit Plan (the “Plan”), effective as of the same date. The Plan permits the awards of phantom units and phantom unit appreciation rights to any employee or non-employee director of the Partnership, including its executive officers. The awards may be time-based or performance-based and will be paid, if at all, in cash.

The award of a phantom unit entitles the participant to a cash payment equal to the value of the phantom unit on the vesting date or dates, which value is the fair market value of a common unit of the Partnership (a “Unit”) on such vesting date or dates. The award of a phantom unit appreciation right entitles the recipient to a cash payment equal to the difference between the value of a phantom unit on the vesting date or dates in excess of the value assigned by the Compensation Committee to the phantom unit as of the grant date. Phantom units and phantom unit appreciation rights granted to participants do not confer upon participants any right to a Unit.

On February 11, 2025, the Compensation Committee approved forms of time-based award agreements for phantom units and phantom unit appreciation rights, both of which awards vest in full on July 21, 2027. The grant date value of a phantom unit under a phantom unit appreciation right award is equal to the average of the closing price for a Unit during the 20 trading days immediately preceding the grant date of the award.

Generally, vesting of an award is subject to a participant remaining continuously employed with the Partnership through the vesting date. However, if prior to the vesting date (i) a participant is terminated without cause (as defined in the time-based award agreements) or terminates employment after the participant has attained age 65 and ten years of employment (“retirement-eligible”), a prorated portion of the award will vest and be paid in cash no later than the 30th day following such termination date (subject to a six-month delay in payment for certain retirement-eligible participants) or (ii) there is a change in control of the Partnership (as defined in the Plan), the award will vest in full and be paid in cash no later than the 30th day following the date of the change of control; provided, however, the participant has been in continuous employment through the termination or change in control date, as applicable.

On February 11, 2025, 1,210,000 phantom units and 425,000 phantom unit appreciation rights were granted to employees of the general partner and its affiliates who perform services for the Partnership.

The foregoing summary of the Plan is qualified in its entirety by reference to the complete text of the Plan, the form of award agreement for phantom units and the form of award agreement for phantom unit appreciation rights, copies of which are filed as Exhibits 10.2, 10.3 and 10.4 to this Current Report on Form 8-K and are incorporated herein by reference.
