Martin Midstream Partners (NASDAQ: MMLP) turns Q2 2026 profit while carrying heavy debt
Martin Midstream Partners L.P. reported stronger results for the three months ended June 30, 2026, with total revenues of $213,600 (thousands) compared with $180,676 (thousands) a year earlier and net income of $2,647 (thousands) versus a prior-year loss. Operating income rose to $19,258 (thousands), supported by growth across transportation, sulfur services and specialty products.
For the first six months of 2026, revenues reached $401,274 (thousands), but the partnership recorded a net loss of $4,113 (thousands) and used $1,577 (thousands) of cash in operating activities, driven largely by working-capital swings. Long-term debt increased to $453,748 (thousands), and partners’ capital remained in a deficit of $90,213 (thousands). A March 2026 amendment reduced the revolving credit facility to $115,000 and tightened interest coverage and leverage covenants, though all requirements were met and management expects continued compliance.
Contracted minimum future revenues under long-term customer and service agreements totaled $380,072 (thousands), providing multi-year visibility. The partnership also declared a quarterly cash distribution of $0.005 per common unit for the second quarter of 2026, or $0.020 per common unit on an annualized basis.
Positive
- Returned to quarterly profitability in Q2 2026, with net income of $2,647 (thousands) versus a loss a year earlier and operating income of $19,258 (thousands).
- Improved revenue scale and future visibility, as quarterly revenues rose to $213,600 (thousands) and remaining performance obligations totaled $380,072 (thousands) under long-term commercial agreements.
Negative
- Year-to-date losses and cash outflow, with a six-month net loss of $4,113 (thousands) and operating cash outflow of $1,577 (thousands), contrasting with positive operating cash flow in the prior-year period.
- Elevated leverage and reduced revolver capacity, with long-term debt of $453,748 (thousands), partners’ capital in a deficit of $90,213 (thousands), and the revolving credit facility reduced to $115,000.
Filing Explained
The filing leaves existing holders with a larger unit base and the partnership with $50 thousand of cash against $453,748 thousand of long-term debt.
As an unaudited quarterly report, this Form 10-Q updates Martin Midstream Partners’ interim financial position and liquidity through
The six-month statement also records issuance of 69,600 restricted units, leaving 39,124,686 common units outstanding at June 30. Under the supplied dilution definition, issuing additional shares increases the total share count and reduces existing holders’ percentage ownership absent offsetting changes; here, the disclosed issuance therefore dilutes existing common holders’ percentage interest.
The filing states that common limited partner units represent a 98% partnership interest, Martin Resource Management Corporation owns approximately 20.1% of the outstanding common units, and MMGP owns a 2% general partner interest. It further states that the general partner’s management role and the affiliate’s ownership effectively give Martin Resource Management Corporation the ability to veto some partnership actions and control management.

6 terms
Interest Coverage Ratio financial
"require the Partnership to maintain a minimum Interest Coverage Ratio of at least 1.65 to 1.00"
A measure of how easily a company can pay the interest on its debt, calculated by comparing the earnings it generates from operations to the interest it owes. It matters to investors because a higher ratio means the company can comfortably meet interest payments — like having several paychecks set aside to cover your rent — while a low ratio signals greater risk of missed payments or financial strain.
Total Leverage Ratio financial
"require the Partnership to maintain a maximum Total Leverage Ratio of not more than 5.50 to 1.00"
phantom units financial
"The 2025 Plan permits the awards of phantom units and phantom unit appreciation rights"
Phantom units are a form of employee compensation that mimics ownership in a company without issuing real shares: recipients receive cash or stock value tied to the company’s share price or performance when the units vest. They matter to investors because phantom units align employee incentives with shareholder value while avoiding share dilution; however, they create future cash obligations and can affect a company’s financial statements and cash flow.
asset retirement obligations financial
"The schedule below summarizes the changes in our asset retirement obligations"
Asset retirement obligations are a company’s recorded promise to pay for dismantling, cleaning up, or restoring property when a long-lived asset is retired — for example decommissioning a plant or removing equipment. Companies estimate the future cleanup cost today and book it as a liability (and add the cost to the asset), so it affects the balance sheet, reported profits over time, and future cash needs; investors watch it like a planned bill that can reduce cash available for returns.

Forward-Looking Statements
This Quarterly Report on Form 10-Q includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Statements included in this quarterly report that are not historical facts (including any statements concerning plans and objectives of management for future operations or economic performance, or assumptions or forecasts related thereto), including, without limitation, the information set forth in Management’s Discussion and Analysis of Financial Condition and Results of Operations, are forward-looking statements. These statements can be identified by the use of forward-looking terminology including "forecast," "may," "believe," "will," "expect," "anticipate," "estimate," "continue," or other similar words. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other "forward-looking" information. We and our representatives may from time to time make other oral or written statements that are also forward-looking statements.
These forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.
Because these forward-looking statements involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons, including those discussed under "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the Securities and Exchange Commission (the "SEC") on February 23, 2026, and as may be updated and supplemented from time to time in our future Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.

Martin Midstream Partners L.P. (the "Partnership") is a publicly traded limited partnership with a diverse set of operations focused primarily in the Gulf Coast region of the United States ("U.S."). Its four primary business lines include: terminalling, processing, and storage services for petroleum products and by-products; land and marine transportation services for petroleum products and by-products, chemicals, and specialty products; sulfur and sulfur-based products processing, manufacturing, marketing and distribution; and marketing, distribution, and transportation services for natural gas liquids ("NGL") and blending and packaging services for specialty lubricants and greases.
The Partnership’s unaudited consolidated and condensed financial statements have been prepared in accordance with the requirements of Form 10-Q and U.S. Generally Accepted Accounting Principles ("U.S. GAAP") for interim financial reporting. Accordingly, these financial statements have been condensed and do not include all of the information and footnotes required by U.S. GAAP for annual audited financial statements of the type contained in the Partnership’s annual reports on Form 10-K. In the opinion of the management of Martin Midstream GP LLC ("MMGP" or the “general partner"), the Partnership’s general partner, all adjustments and elimination of significant intercompany balances necessary for a fair presentation of the Partnership’s financial position, results of operations, and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. Results for such interim periods are not necessarily indicative of the results of operations for the full year. These financial statements should be read in conjunction with the Partnership’s audited consolidated financial statements and notes thereto included in the Partnership’s annual report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 23, 2026.
Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these consolidated and condensed financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates.

Revenue is measured based on a consideration specified in a contract with a customer and excludes amounts collected on behalf of third parties where the Partnership is acting as an agent. The Partnership recognizes revenue when the Partnership satisfies a performance obligation, which typically occurs when the Partnership transfers control over a product to a customer or as the Partnership delivers a service.
The following is a description of the principal activities - separated by reportable segments - from which the Partnership generates revenue.
Terminalling and Storage Segment
Revenue is recognized for storage contracts based on the contracted monthly tank fixed fee. For throughput contracts, revenue is recognized based on the volume moved through the Partnership’s terminals at the contracted rate. For storage and throughput contracts at the Partnership's underground NGL storage facility, revenue is recognized based on the volume stored and moved through the facility at the contracted rate. For the Partnership’s tolling agreement, revenue is recognized based on the contracted monthly reservation fee and throughput volumes moved through the facility. Throughput and storage revenue in the table above includes non-cancelable revenue arrangements that are under the scope of ASC 842, whereby the Partnership has committed certain Terminalling and Storage assets in exchange for a minimum fee.
Transportation Segment
Revenue related to land transportation is recognized for line hauls based on a mileage rate. For contracted trips, revenue is recognized upon completion of the particular trip. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

(Unaudited)
Revenue related to marine transportation is recognized for time charters based on a per day rate. For contracted trips, revenue is recognized upon completion of the particular trip. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.
Sulfur Services Segment
Revenue from sulfur and fertilizer product sales is recognized when the customer takes title to the product. Delivery of the product is invoiced as the transaction occurs and is generally paid within a month. Revenue from sulfur services is recognized as services are performed during each monthly period. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.
Specialty Products Segment
NGL revenue is recognized when title is transferred, which is generally when the product is delivered by truck, rail, or pipeline to the Partnership's NGL customers or when the customer picks up the product from our facilities. When lubricants are sold by truck or rail, revenue is recognized when title is transferred, which is generally when the product leaves the Partnership's facility, but can vary based on the specific terms of the contract. The product is invoiced as the transaction occurs and is generally paid within a month.

The applicable margin for revolving loans that are SOFR loans ranges from 2.75 % to 3.75 %, and the applicable margin for revolving loans that are alternate base rate loans ranges from 1.75 % to 2.75 %. The applicable margin for SOFR borrowings and alternate base rate borrowings at June 30, 2026 is 3.75 % and 2.75 %, respectively. The applicable margin for SOFR borrowings and alternate base rate borrowings effective July 22, 2026, is 3.75 % and 2.75 %, respectively. The credit facility contains various covenants that limit the Partnership’s ability to make distributions; make certain investments and acquisitions; enter into certain agreements; incur indebtedness; sell assets; and make certain amendments to the Partnership's omnibus agreement with Martin Resource Management Corporation (as amended, the "Omnibus Agreement").
2 The Partnership was in compliance with all debt covenants as of June 30, 2026 and December 31, 2025.
3 On March 31, 2026, the Partnership, Martin Operating Partnership L.P. (the “Operating Partnership”), a wholly owned subsidiary of the Partnership, and certain of the Partnership’s other subsidiaries entered into a Third Amendment to Fourth Amended and Restated Credit Agreement (the “Third Amendment”) with Royal Bank of Canada, as administrative agent and collateral agent, and the lenders party thereto, which amends the Fourth Amended and Restated Credit Agreement, dated effective as of February 8, 2023 (as previously amended, the “Credit Agreement”).
The Third Amendment amended the Credit Agreement to, among other things:
•decrease the amount available for the Partnership to borrow under the Credit Agreement on a revolving credit basis from $130,000 to $115,000 ; and
•adjust the financial covenants as described in more detail below:
◦require the Partnership to maintain a minimum Interest Coverage Ratio (as defined in the Credit Agreement) of at least 1.65 1.75 to 1.00 for the fiscal quarter ending March 31, 2027 and each fiscal quarter thereafter; and
The Partnership is in compliance with all debt covenants as of June 30, 2026, and expects to be in compliance for the next twelve months.

Capitalized interest was $235 and $45 for the six months ended June 30, 2026 and 2025, respectively.
NOTE 6. LEASES
The Partnership has numerous operating leases primarily for terminal facilities and transportation and other equipment. The leases generally provide that all expenses related to the facilities and equipment are to be paid by the lessee.
Operating lease Right-of-Use assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. Because most of the Partnership's leases do not provide an implicit rate of return, the Partnership uses its imputed collateralized rate based on the information available at commencement date in determining the present value of lease payments. The estimated rate is based on a risk-free rate plus a risk-adjusted margin.
Our leases have remaining lease terms of 1 year to 11 years, some of which include options to extend the leases for up to 5 years, and some of which include options to terminate the leases within 1 year. The Partnership includes extension periods in its lease term if, at commencement, it is reasonably likely that the Partnership will exercise the extension options.

NOTE 8. PARTNERS' CAPITAL (DEFICIT)
As of June 30, 2026, Partners’ capital (deficit) consisted of 39,124,686 common limited partner units, representing a 98 % partnership interest, and a 2 % general partner interest. Martin Resource Management Corporation, through subsidiaries, owned 7,874,446 of the Partnership's common limited partner units representing approximately 20.1 % of the Partnership's outstanding common limited partner units. MMGP, the Partnership's general partner, owns the 2 % general partnership interest.
The partnership agreement of the Partnership (the "Partnership Agreement") contains specific provisions for the allocation of net income and losses to each of the partners for purposes of maintaining their respective partner capital accounts.
Impact on Partners' Capital (Deficit) Related to Transactions Between Entities Under Common Control
Under ASC 805, assets and liabilities transferred between entities under common control are accounted for at the historical cost of those entities' ultimate parent, in a manner similar to a pooling of interests. Any difference in the amount paid by the transferee versus the historical cost of the assets transferred is recorded as an adjustment to equity (contribution or distribution) by the transferee. This is in contrast with a business combination between unrelated parties, where assets and liabilities are recorded at their fair values at the acquisition date, with any excess of amounts paid over the fair value representing goodwill. From time to time, the most recent being in 2019, the Partnership has entered into common control acquisitions from Martin Resource Management Corporation. The consideration transferred totaling $552,058 exceeds the historical cost of the net assets received. This excess of the purchase price over the historical cost of the net assets received has resulted in cumulative deemed distributions of $289,019 reflected as reductions to Partners' capital.
Distributions of Available Cash
The Partnership distributes all of its available cash (as defined in the Partnership Agreement) within 45 days after the end of each quarter to unitholders of record and to the general partner. Available cash is generally defined as all cash and cash equivalents of the Partnership on hand at the end of each quarter less the amount of cash reserves its general partner determines in its reasonable discretion is necessary or appropriate to: (i) provide for the proper conduct of the Partnership’s business; (ii) comply with applicable law, any debt instruments or other agreements; or (iii) provide funds for distributions to unitholders and the general partner for any one or more of the next four quarters, plus all cash on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.
Net Income per Unit
The Partnership follows the provisions of the FASB ASC 260-10 related to earnings per share, which addresses the application of the two-class method in determining income per unit for master limited partnerships having multiple classes of securities that may participate in partnership distributions accounted for as equity distributions. Undistributed earnings are allocated to the general partner and limited partners utilizing the contractual terms of the Partnership Agreement. When current period distributions are in excess of earnings, the excess distributions for the period are to be allocated to the general partner and limited partners based on their respective sharing of income and losses specified in the Partnership Agreement. Additionally, as required under FASB ASC 260-10-45-61A, unvested share-based payments that entitle employees to receive non-forfeitable distributions are considered participating securities, as defined in FASB ASC 260-10-20, for earnings per unit calculations.
For purposes of computing diluted net income per unit, the Partnership uses the more dilutive of the two-class and if-converted methods. Under the if-converted method, the weighted-average number of subordinated units outstanding for the period is added to the weighted-average number of common units outstanding for purposes of computing basic net income per unit and the resulting amount is compared to the diluted net income per unit computed using the two-class method. The following is a reconciliation of net income allocated to the general partner and limited partners for purposes of calculating net income attributable to limited partners per unit:

All outstanding units were included in the computation of diluted earnings per unit and weighted based on the number of days such units were outstanding during the periods presented. For the three months ended June 30, 2026, all common unit equivalents were excluded from the computation of diluted earnings per unit because their effect would have been antidilutive under the treasury stock method, as the sum of the assumed proceeds and unrecognized compensation cost per unit exceeded the average market price of the common units for the period. All common unit equivalents were antidilutive for the six months ended June 30, 2026 and for the three and six months ended June 30, 2025 because the limited partners were allocated a net loss in those periods.
NOTE 9. UNIT BASED AWARDS - LONG-TERM INCENTIVE PLANS
The Partnership recognizes compensation costs related to unit-based awards to both employees and non-employees in its consolidated and condensed financial statements in accordance with certain provisions of ASC 718. Amounts recognized in operating expense and selling, general, and administrative expense in the consolidated and condensed financial statements with respect to these plans are as follows:

Long-Term Incentive Plans
The Partnership's general partner has long-term incentive plans for employees and directors of the general partner and its affiliates who perform services for the Partnership.
2021 Phantom Unit Plan
On July 21, 2021, the board of directors of the general partner of the Partnership (the "Board") and the compensation committee of the Board (the "Compensation Committee") approved the Martin Midstream Partners L.P. 2021 Phantom Unit Plan (the “Plan”), effective as of the same date. The Plan permits the awards of phantom units and phantom unit appreciation rights (collectively, "phantom unit awards") 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 July 21, 2021, 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 the third anniversary of the grant date. 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 award agreement) or terminates employment after the participant has attained both the age of 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, that the participant has been in continuous employment through the termination or change in control date, as applicable.
On April 20, 2022, the Board and the Compensation Committee approved the First Amendment to the Plan, effective as of the same date, which amendment increased the total number of phantom units available for grant under the Plan from 2,000,000 units to 5,000,000 units. On April 20, 2022, 365,000 phantom units and 1,097,500 phantom unit appreciation rights were granted to employees of the general partner and its affiliates who perform services for the Partnership. These units settled in July of 2025 for $1,123 . On July 19, 2023, 1,179,500 phantom units and 505,500 phantom unit appreciation rights were granted to employees of the general partner and its affiliates who perform services for the Partnership.
2025 Phantom Unit Plan
On February 11, 2025, the Board and the Compensation Committee approved the Martin Midstream Partners L.P. 2025 Phantom Unit Plan (the “2025 Plan”) to supersede the 2021 Plan, effective as of the same date. The 2025 Plan contains substantially the same terms and conditions as the 2021 Plan. 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. On July 16, 2025, 1,275,000 phantom units and 420,000 phantom unit appreciation rights were granted to employees of the general partner and its affiliates who perform services for the Partnership. The 2025 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.
Phantom unit awards are recorded in operating expense and selling, general and administrative expense based on the fair value of the awards on the balance sheet date. The fair value of these awards is updated at each balance sheet date and

MARTIN MIDSTREAM PARTNERS L.P.
NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS

June 30, 2026
(Unaudited)
changes in the fair value of the awards are recorded as increases or decreases to compensation expense within operating expense and selling, general and administrative expense in the Consolidated and Condensed Statements of Operations. All of the Partnership's phantom unit awards outstanding as of June 30, 2026 met the criteria to be treated under liability classification in accordance with ASC 718, given that these awards will settle in cash on the vesting date.
Compensation expense for the phantom awards is based on the fair value of the units as of the balance sheet date as further discussed below, and such costs are recognized ratably over the service period of the awards. As the fair value of liability awards is required to be re-measured each period end, stock compensation expense amounts recognized in future periods for these awards will vary. The estimated future cash payments of these awards are presented as liabilities within "Trade and other accounts payable" and "Other long-term obligations" in the Consolidated and Condensed Balance Sheets. At June 30, 2026, the total liability recognized in connection with outstanding phantom unit awards was $5,079 , of which $2,570 is recorded in Trade and other accounts payable and $2,509 is recorded in Other long-term obligations on the Consolidated and Condensed Balance Sheets. At December 31, 2025, the total liability recognized in connection with outstanding phantom unit awards was $4,574 , of which $2,905 is recorded in Trade and other accounts payable and $1,669 is recorded in Other long-term obligations on the Consolidated and Condensed Balance Sheets. As of June 30, 2026, there was a total of $3,291 of unrecognized compensation costs related to phantom unit awards. These costs are expected to be recognized over a remaining life of 1.66 years.
The fair value of the phantom unit awards was estimated using a Monte Carlo valuation model as of the balance sheet date. The Monte Carlo valuation model is based on random projections of stock price paths and must be repeated numerous times to achieve a probabilistic assessment. Expected volatility was calculated based on the historical volatility of the Partnership’s common units as well as those of a set of its peer companies.
Restricted Unit Plan
On May 26, 2017, the unitholders of the Partnership approved the Martin Midstream Partners L.P. 2017 Restricted Unit Plan (the "2017 LTIP"). The 2017 LTIP currently permits the grant of awards covering an aggregate of 3,000,000 common units, all of which can be awarded in the form of restricted units. The 2017 LTIP is administered by the Compensation Committee.
A restricted unit is a unit that is granted to grantees with certain vesting restrictions, which may be time-based and/or performance-based. Once these restrictions lapse, the grantee is entitled to full ownership of the unit without restrictions. The Compensation Committee may determine to make grants under the 2017 LTIP containing such terms as the Compensation Committee shall determine under the 2017 LTIP. With respect to time-based restricted units ("TBRUs"), the Compensation Committee will determine the time period over which restricted units granted to employees and directors will vest. The Compensation Committee may also award a percentage of restricted units with vesting requirements based upon the achievement of specified pre-established performance targets ("Performance Based Restricted Units" or "PBRUs"). The performance targets may include, but are not limited to, the following: revenue and income measures, cash flow measures, net income before interest expense and income tax expense, net income before interest expense, income tax expense, and depreciation and amortization ("EBITDA"), distribution coverage metrics, expense measures, liquidity measures, market measures, corporate sustainability metrics, and other measures related to acquisitions, dispositions, operational objectives and succession planning objectives. PBRUs are earned only upon our achievement of an objective performance measure for the performance period. PBRUs which vest are payable in common units. Unvested units granted under the 2017 LTIP may or may not participate in cash distributions depending on the terms of each individual award agreement.
The restricted units issued to directors generally vest in equal annual installments over a four-year period. Restricted units issued to employees generally vest in equal annual installments over three years of service. All of the Partnership's outstanding restricted unit awards at June 30, 2026, met the criteria to be treated under equity classification.
On February 17, 2026, the Partnership issued 23,200 TBRUs to each of the Partnership's three independent directors under the 2017 LTIP. These restricted common units vest in equal installments of 5,800

NOTE 10. RELATED PARTY TRANSACTIONS
As of June 30, 2026, Martin Resource Management Corporation owns 7,874,446 of the Partnership’s common units representing approximately 20.1 % of the Partnership’s outstanding limited partner units. Martin Resource Management Corporation controls the Partnership's general partner by virtue of its 100 % voting interest in MMGP Holdings, LLC ("Holdings"), the sole member of the Partnership's general partner. The Partnership’s general partner, MMGP, owns a 2 % general partner interest in the Partnership. The Partnership’s general partner’s ability, as general partner, to manage and operate the Partnership, and Martin Resource Management Corporation’s ownership as of June 30, 2026, of approximately 20.1 % of the Partnership’s outstanding limited partnership units, effectively gives Martin Resource Management Corporation the ability to veto some of the Partnership’s actions and to control the Partnership’s management.
The following is a description of the Partnership’s material related party agreements and transactions:
Omnibus Agreement
Omnibus Agreement. The Partnership and its general partner are parties to the Omnibus Agreement dated November 1, 2002, with Martin Resource Management Corporation that governs, among other things, potential competition and indemnification obligations among the parties to the agreement, related party transactions, the provision of general administration and support services by Martin Resource Management Corporation and the Partnership’s use of certain Martin Resource Management Corporation trade names and trademarks. The Omnibus Agreement was amended on (i) November 25, 2009, to include processing crude oil into finished products including naphthenic lubricants, distillates, asphalt and other intermediate cuts, (ii) October 1, 2012, to permit the Partnership to provide certain lubricant packaging products and services to Martin Resource Management Corporation and (iii) October 17, 2023 to include lubricants and packaging in the Partnership’s definition of business.

Services. Under the Omnibus Agreement, Martin Resource Management Corporation provides the Partnership with corporate staff, support services, and administrative services necessary to operate the Partnership’s business. The Omnibus Agreement requires the Partnership to reimburse Martin Resource Management Corporation for all direct expenses it incurs or

payments it makes on the Partnership’s behalf or in connection with the operation of the Partnership’s business. There is no monetary limitation on the amount the Partnership is required to reimburse Martin Resource Management Corporation for direct expenses. In addition to the direct expenses, under the Omnibus Agreement, the Partnership is required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses.
Effective January 1, 2026, through December 31, 2026, the Conflicts Committee approved an annual reimbursement amount for indirect expenses of $12,953 . The Partnership reimbursed Martin Resource Management Corporation for $3,238 and $3,384 of indirect expenses for the three months ended June 30, 2026 and 2025, respectively. The Partnership reimbursed Martin Resource Management Corporation for $6,477 and $6,768 of indirect expenses for the six months ended June 30, 2026 and 2025, respectively. The Conflicts Committee will review and approve future adjustments in the reimbursement amount for indirect expenses, if any, annually.
These indirect expenses are intended to cover the centralized corporate functions Martin Resource Management Corporation provides to the Partnership, such as accounting, treasury, clerical, engineering, legal, billing, information technology, administration of insurance, general office expenses and employee benefit plans and other general corporate overhead functions the Partnership shares with Martin Resource Management Corporation retained businesses. The provisions of the Omnibus Agreement regarding Martin Resource Management Corporation’s services will terminate if Martin Resource Management Corporation ceases to control the general partner of the Partnership.
Related-Party Transactions. The Omnibus Agreement prohibits the Partnership from entering into any material agreement with Martin Resource Management Corporation without the prior approval of the Conflicts Committee. For purposes of the Omnibus Agreement, the term "material agreements" means any agreement between the Partnership and Martin Resource Management Corporation that requires aggregate annual payments in excess of the then-applicable agreed upon reimbursable amount of indirect general and administrative expenses. Please read "Services" above.
License Provisions. Under the Omnibus Agreement, Martin Resource Management Corporation has granted the Partnership a nontransferable, nonexclusive, royalty-free right and license to use certain of its trade names and marks, as well as the trade names and marks used by some of its affiliates.
Amendment and Termination. The Omnibus Agreement may be amended by written agreement of the parties; provided, however, that it may not be amended without the approval of the Conflicts Committee if such amendment would adversely affect the unitholders. The Omnibus Agreement was amended on (i) November 25, 2009, to permit the Partnership to provide refining services to Martin Resource Management Corporation, (ii) October 1, 2012, to permit the Partnership to provide certain lubricant packaging products and services to Martin Resource Management Corporation and (iii) October 17, 2023 to include lubricants and packaging in the Partnership’s definition of business. Such amendments were approved by the Conflicts Committee. The Omnibus Agreement, other than the indemnification provisions and the provisions limiting the amount for which the Partnership will reimburse Martin Resource Management Corporation for general and administrative services performed on its behalf, will terminate if the Partnership is no longer an affiliate of Martin Resource Management Corporation.
Master Transportation Services Agreement
Master Transportation Services Agreement. Martin Transport, Inc. ("MTI"), a wholly owned subsidiary of the Partnership, is a party to a master transportation services agreement effective January 1, 2019, with certain wholly owned subsidiaries of Martin Resource Management Corporation.

Marine Agreements
Marine Transportation Agreement. The Partnership is a party to a marine transportation agreement effective January 1, 2006, as amended, under which the Partnership provides marine transportation services to Martin Resource Management Corporation on a spot-contract basis at applicable market rates. Effective each January 1, this agreement automatically renews for consecutive one year periods unless either party terminates the agreement by giving written notice to the other party at least 60 days prior to the expiration of the then applicable term. The fees the Partnership charges Martin Resource Management Corporation are based on applicable market rates.
Marine Fuel. The Partnership is a party to an agreement with Martin Resource Management Corporation dated November 1, 2002, under which Martin Resource Management Corporation provides the Partnership with marine fuel from its locations in the Gulf of Mexico at a fixed rate in excess of the Platt’s U.S. Gulf Coast Index for #2 Fuel Oil. Under this agreement, the Partnership agreed to purchase all of its marine fuel requirements that occur in the areas serviced by Martin Resource Management Corporation.
Terminal Services Agreements
Diesel Fuel Terminal Services Agreement. Effective October 1, 2022, the Partnership entered into a third amended and restated terminalling services agreement under which it provides terminal services to Martin Energy Services LLC (“MES”), a wholly owned subsidiary of Martin Resource Management Corporation, for fuel distribution utilizing marine shore based terminals owned by the Partnership. This agreement amended the existing arrangement between the Partnership and MES by eliminating any minimum throughput volume requirements and increasing the per gallon throughput fee. The primary term of this agreement expired on December 31, 2023, but will continue on a year to year basis until terminated by either party by giving at least 90 days’ written notice prior to the end of any term. Effective January 1, 2024, this agreement was amended to increase the throughput rate and to establish a minimum throughput volume.
Miscellaneous Terminal Services Agreements. The Partnership is currently party to several terminal services agreements and from time to time the Partnership may enter into other terminal service agreements for the purpose of providing terminal services to related parties. Individually, each of these agreements is immaterial but when considered in the aggregate they could be deemed material. These agreements are throughput based with a minimum volume commitment. Generally, the fees due under these agreements are adjusted annually based on a price index.
Other Agreements
Cross Tolling Agreement. The Partnership is a party to an amended and restated tolling agreement with Cross Oil Refining and Marketing, Inc. ("Cross") dated October 28, 2014, under which the Partnership processes crude oil into finished products, including naphthenic lubricants, distillates, asphalt and other intermediate cuts for Cross. The tolling agreement expires November 25, 2031. Under this tolling agreement, Cross agreed to process a minimum of 6,500 barrels per day of crude oil at the facility at a fixed price per barrel. Any additional barrels are processed at a modified price per barrel. In addition, Cross agreed to pay a monthly reservation fee and a periodic fuel surcharge fee based on certain parameters specified in the tolling agreement. Further, certain capital improvements, to the extent requested by Cross, are reimbursed through a capital recovery fee. All of these fees (other than the fuel surcharge) are subject to escalation annually based upon an amount equal to two-thirds (2/3) times the increase in the Consumer Price Index for a specified annual period.
East Texas Mack Leases. MTI leases equipment, including tractors and trailers, from East Texas Mack Sales ("East Texas Mack").

NOTE 11. BUSINESS SEGMENTS
The Chief Operating Decision Maker ("CODM") is a group of executives, comprised of the Chief Executive Officer, Chief Financial Officer and Chief Operating Officer of the Partnership's general partner. The CODM may use different operating measures to assess operating results and allocate resources among the Partnership's four segments (outlined below), however the measure that is most consistent with the amounts included in the consolidated financial statements is operating income. The CODM utilizes this measure to evaluate the current financial performance and project the future financial performance of each segment to determine the allocation of capital resources.
The Partnership's four reportable segments are comprised of (1) Terminalling and Storage, (2) Transportation, (3) Sulfur Services and (4) Specialty Products. The operating segments within each of our reportable segments have been aggregated based on the similarity of their economic and other characteristics, including different product type and services.
The Terminalling and Storage segment generates revenue by providing terminalling, processing, and storage services for petroleum products and by-products. Storage revenue is earned through contracted monthly tank fixed fees, while throughput revenue is based on the volume moved through the Partnership’s terminals at contracted rates. Tolling revenue is derived from contracted monthly reservation fees and throughput volumes processed at the facility.
The Transportation segment earns revenue by offering land and marine transportation services for petroleum products, by-products, chemicals, and specialty products. Land transportation revenue is based on mileage rates for line hauls or completion of contracted trips. Marine transportation revenue comes from time charters, calculated on a per-day basis, or from the completion of contracted trips.
The Sulfur Services segment generates revenue by providing processing, manufacturing, marketing, and distribution services for sulfur and sulfur-based products. Revenue from sulfur and fertilizer product sales is recognized when the customer takes title to the product. Revenue from sulfur services is earned as services are performed during each monthly period.

The Specialty Products segment earns revenue by providing marketing, distribution, and transportation services for NGLs as well as blending and packaging services for specialty lubricants and greases. NGL revenue is recognized upon the sale of products via truck, rail, or pipeline. For lubricants and greases, revenue is recognized upon their sale by truck or rail.

NOTE 12. COMMITMENTS AND CONTINGENCIES
Contingencies
From time to time, the Partnership is subject to various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Partnership.
On December 31, 2015, the Partnership received a demand from a customer in its lubricants packaging business for defense and indemnity in connection with various lawsuits filed against it, which generally alleged that the customer engaged in unlawful and deceptive business practices in connection with its marketing and advertising of its private label motor oil (the “Marketing Lawsuits”). The Partnership disputed and continues to dispute that it has any obligation to defend or indemnify the customer for the customer’s conduct. Accordingly, on January 7, 2016, the Partnership filed a Complaint for Declaratory Judgment in the Chancery Court of Davidson County, Tennessee (the “Tennessee Court”), under Case No. 16-0018-BC, requesting a judicial determination that the Partnership did not owe the customer the demanded defense and indemnity obligations (the “Litigation”). The Marketing Lawsuits pending in federal court against the customer were transferred to the U.S. District Court for the Western District of Missouri under the consolidated case MDL No. 2709 for pretrial proceedings (the “Consolidated Lawsuits”). On March 1, 2017, at the joint request of the customer and the Partnership, the Tennessee Court administratively closed the Litigation. In 2021, the customer settled the Consolidated Lawsuits. On December 17, 2021, at the request of the customer, the Tennessee Court reopened the Litigation and the customer asserted various counterclaims against the Partnership seeking, among other things, to recover its costs of defending and settling the Consolidated Lawsuits. At this time, we are unable to determine what ultimate exposure we may have in this matter, if any. The Partnership intends to vigorously defend the counterclaims asserted by the customer in the Litigation. The trial for the Litigation is scheduled to be held August 2 through August 6, 2027.
NOTE 13. FAIR VALUE MEASUREMENTS
Level 1: Quoted market prices in active markets for identical assets or liabilities.
Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.
Level 3: Unobservable inputs that reflect the entity's own assumptions and are not corroborated by market data.
•Accounts and other receivables, trade and other accounts payable, accrued interest payable, other accrued liabilities, income taxes payable and due from/to affiliates: The carrying amounts approximate fair value due to the short maturity and highly liquid nature of these instruments, and as such these have been excluded from the table below. There is negligible credit risk associated with these instruments.

NOTE 14. INVESTMENT IN DSM SEMICHEM LLC
On October 19, 2022, Martin ELSA Investment LLC, the Partnership's affiliate, entered into definitive agreements with Samsung C&T America, Inc. and Dongjin USA, Inc., an affiliate of Dongjin Semichem Co., Ltd., to form DSM Semichem LLC (“DSM”). DSM will produce and distribute electronic level sulfuric acid (“ELSA”). By leveraging the Partnership's existing assets located in Plainview, Texas and installing additional facilities (the “ELSA Facility”) as required, DSM will produce ELSA that meets the strict quality standards required by the recent advances in semiconductor manufacturing. In addition to owning a 10 % non-controlling interest in DSM, the Partnership will be the exclusive provider of feedstock to the ELSA Facility. The Partnership, through its affiliate MTI, will also provide land transportation services for the ELSA produced by DSM. On April 1, 2024, the Partnership contributed $6,500 in cash to DSM, which represents the cash contributions required pursuant to DSM's limited liability agreement for the Partnership's 10 % non-controlling interest. Also, in conjunction with the formation of DSM, we contributed approximately 22 acres of land. The Partnership recognizes its 10 % interest in DSM as "Investment in DSM Semichem LLC" on its Consolidated and Condensed Balance Sheets. The Partnership accounts for its ownership interest in DSM under the equity method of accounting.

Current state income taxes attributable to the Texas margin tax relating to the operation of the Partnership of $282 and $687 were recorded in income tax expense for the six months ended June 30, 2026 and 2025, respectively. Deferred taxes applicable to the Texas margin tax relating to the operation of the Partnership are immaterial.
MTI, a wholly owned subsidiary of the Partnership, is subject to income taxes due to its corporate structure (the "Taxable Subsidiary"). Total income tax expense of $1,633 and $1,814 , related to the operation of the Taxable Subsidiary, for the three months ended June 30, 2026 and 2025, resulted in an effective income tax rate ("ETR") of 67.04 % and 64.50 %, respectively. Total income tax expense of $2,111 and $2,514 , related to the operation of the Taxable Subsidiary, for the six months ended June 30, 2026 and 2025, resulted in an effective income tax rate of 56.44 % and 50.84 %, respectively.
The increase in the effective tax rate for the three and six months ended June 30, 2026, compared to the U.S. federal statutory rate of 21%, is primarily due to state income taxes, net of the federal benefit, and nondeductible insurance premiums. The relatively low pre-tax income causes the permanent differences and state taxes to have a proportionately larger effect on the effective tax rate.
A current federal income tax expense of $984 and $1,514 , related to the operation of the Taxable Subsidiary, was recorded for the three months ended June 30, 2026 and 2025, respectively. A current federal income tax expense of $1,245 and $2,235 , related to the operation of the Taxable Subsidiary, was recorded for the six months ended June 30, 2026 and 2025, respectively. A current state income tax expense of $253 and $240 , related to the operation of the Taxable Subsidiary, was recorded for the three months ended June 30, 2026 and 2025, respectively. A current state income tax expense of $328 and $433 , related to the operation of the Taxable Subsidiary, was recorded for the six months ended June 30, 2026 and 2025, respectively.
With respect to MTI, income taxes are accounted for under the asset and liability method pursuant to the provisions of ASC 740 related to income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable

to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.
A deferred tax expense related to the MTI temporary differences of $396 and $60 was recorded for the three months ended June 30, 2026 and 2025, respectively. A deferred tax expense (benefit) related to the MTI temporary differences of $538 and $(154 ) was recorded for the six months ended June 30, 2026 and 2025, respectively. A net deferred tax asset of $8,488 and $9,026 , related to the cumulative book and tax temporary differences, existed at June 30, 2026 and December 31, 2025, respectively.
All income tax positions taken for all open years are more likely than not to be sustained based upon their technical merit under applicable tax laws.

| Item 2. | Management’s Discussion and Analysis of Financial Condition and Results of Operations | ||||
You should read the following discussion of our financial condition and results of operations in conjunction with the consolidated and condensed financial statements and the notes thereto included elsewhere in this quarterly report.
Overview
We are a publicly traded limited partnership with a diverse set of operations focused primarily in the Gulf Coast region of the U.S. Our four primary business lines include:
•Terminalling, processing, and storage services for petroleum products and by-products;
•Land and marine transportation services for petroleum products and by-products, chemicals, and specialty products;
•Sulfur and sulfur-based products processing, manufacturing, marketing, and distribution; and
•Marketing, distribution, and transportation services for NGLs and blending and packaging services for specialty lubricants and greases.
The petroleum products and by-products we collect, transport, store and market are produced primarily by major and independent oil and gas companies who often turn to third parties, such as us, for the transportation and disposition of these products. In addition to these major and independent oil and gas companies, our primary customers include independent refiners, large chemical companies, and other wholesale purchasers of these products. We operate primarily in the Gulf Coast region of the U.S. This region is a major hub for petroleum refining, natural gas gathering and processing, and support services for the exploration and production industry.
We were formed in 2002 by Martin Resource Management Corporation, a privately-held company whose initial predecessor was incorporated in 1951 as a supplier of products and services to drilling rig contractors. Since then, Martin Resource Management Corporation has expanded its operations through acquisitions and internal expansion initiatives as its management identified and capitalized on the needs of producers and purchasers of petroleum products and by-products and other bulk liquids. Martin Resource Management Corporation is an important supplier and customer of ours. As of June 30, 2026, Martin Resource Management Corporation owned 20.1% of our total outstanding common limited partner units and 100% of MMGP Holdings, LLC ("Holdings"), which is the sole member of Martin Midstream GP LLC ("MMGP"), our general partner. MMGP owns a 2.0% general partner interest in us.
We entered into the Omnibus Agreement that governs, among other things, potential competition and indemnification obligations among the parties to the agreement, related party transactions, the provision of general administration and support services by Martin Resource Management Corporation and our use of certain of Martin Resource Management Corporation’s trade names and trademarks. Under the terms of the Omnibus Agreement, the employees of Martin Resource Management Corporation are responsible for conducting our business and operating our assets.
Martin Resource Management Corporation has operated our business since our inception in 2002. Martin Resource Management Corporation began operating our NGL business in the 1950s and our sulfur business in the 1960s. It began our land transportation business in the early 1980s and our marine transportation business in the late 1980s. It entered into our fertilizer and terminalling and storage businesses in the early 1990s.
Significant Recent Developments
Subsequent Events
Quarterly Distribution. On July 22, 2026, we declared a quarterly cash distribution of $0.005 per common unit for the second quarter of 2026, or $0.020 per common unit on an annualized basis, which will be paid on August 14, 2026 to unitholders of record as of August 7, 2026.

Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations are based on the historical consolidated and condensed financial statements included elsewhere herein. We prepared these financial statements in conformity with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. We routinely evaluate these estimates, utilizing historical experience, consultation with experts and other methods we consider reasonable in the particular circumstances. Our results may differ from these estimates, and any effects on our business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Changes in these estimates could materially affect our financial position, results of operations or cash flows. See the "Critical Accounting Policies and Estimates" section in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 2, "Significant Accounting Policies" in Notes to Consolidated Financial Statements included within our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 23, 2026.

Approval and Review of Related Party Transactions
If we contemplate entering into a transaction, other than a routine or in the ordinary course of business transaction, in which a related person will have a direct or indirect material interest, the proposed transaction is submitted for consideration to the Board or to our management, as appropriate. If the Board is involved in the approval process, it determines whether to refer the matter to the Conflicts Committee, as constituted under our limited partnership agreement. If a matter is referred to the Conflicts Committee, the Conflicts Committee obtains information regarding the proposed transaction from management and determines whether to engage independent legal counsel or an independent financial advisor to advise the members of the
36
committee regarding the transaction. If the Conflicts Committee retains such counsel or financial advisor, it considers such advice and, in the case of a financial advisor, such advisor’s opinion as to whether the transaction is fair and reasonable to us and to our unitholders.
37
Non-GAAP Financial Measures
To assist management in assessing our business, we use the following non-GAAP financial measures: earnings before interest, taxes, and depreciation and amortization ("EBITDA"), Adjusted EBITDA (as defined below), distributable cash flow available to common unitholders (“Distributable Cash Flow”), and free cash flow after growth capital expenditures and principal payments under finance lease obligations ("Adjusted Free Cash Flow"). Our management uses a variety of financial and operational measurements other than our financial statements prepared in accordance with U.S. GAAP to analyze our performance.
Certain items excluded from EBITDA and Adjusted EBITDA are significant components in understanding and assessing an entity's financial performance, such as cost of capital and historical costs of depreciable assets.
Adjusted EBITDA. We define Adjusted EBITDA as EBITDA before unit-based compensation expenses, gains and losses on the disposition of property, plant and equipment, impairment and other similar non-cash adjustments, transaction costs associated with business combination, merger, and divestiture activities, equity in earnings (loss) from unconsolidated entities, and non-cash contractual revenue deferral adjustments. Adjusted EBITDA is used as a supplemental performance and liquidity measure by our management and by external users of our financial statements, such as investors, commercial banks, research analysts, and others, to assess:
•the financial performance of our assets without regard to financing methods, capital structure, or historical cost basis;
•the ability of our assets to generate cash sufficient to pay interest costs, support our indebtedness, and make cash distributions to our unitholders; and
•our operating performance and return on capital as compared to those of other companies in the midstream energy sector, without regard to financing methods or capital structure.
The GAAP measures most directly comparable to Adjusted EBITDA is net income (loss) and net cash provided by (used in) operating activities. Adjusted EBITDA should not be considered an alternative to, or more meaningful than, net income (loss), operating income (loss), net cash provided by (used in) operating activities, or any other measure of financial performance presented in accordance with GAAP. Adjusted EBITDA may not be comparable to similarly titled measures of other companies because other companies may not calculate Adjusted EBITDA in the same manner.
Adjusted EBITDA does not include interest expense, income tax expense, and depreciation and amortization. Because we have borrowed money to finance our operations, interest expense is a necessary element of our costs and our ability to generate cash available for distribution. Because we have capital assets, depreciation and amortization are also necessary elements of our costs. Therefore, any measures that exclude these elements have material limitations. To compensate for these limitations, we believe that it is important to consider Net Income (Loss) and Net Cash Provided by (Used in) Operating Activities as determined under GAAP, as well as Adjusted EBITDA, to evaluate our overall performance.
Distributable Cash Flow. We define Distributable Cash Flow as Net Cash Provided by (Used in) Operating Activities less cash received (plus cash paid) for closed commodity derivative positions included in Accumulated Other Comprehensive Income (Loss), plus changes in operating assets and liabilities which (provided) used cash, less maintenance capital expenditures and plant turnaround costs. Distributable Cash Flow is a significant performance measure used by our management and by external users of our financial statements, such as investors, commercial banks and research analysts, to compare basic cash flows generated by us to the cash distributions we expect to pay unitholders. Distributable Cash Flow is also an important financial measure for our unitholders since it serves as an indicator of our success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not we are generating cash flow at a level that can sustain or support an increase in our quarterly distribution rates. Distributable Cash Flow is also a quantitative standard used throughout the investment community with respect to publicly-traded partnerships because the value of a unit of such an entity is generally determined by the unit's yield, which in turn is based on the amount of cash distributions the entity pays to a unitholder.
Adjusted Free Cash Flow. We define Adjusted Free Cash Flow as Distributable Cash Flow less growth capital expenditures and principal payments under finance lease obligations. Adjusted Free Cash Flow is a significant performance measure used by our management and by external users of our financial statements and represents how much cash flow a business generates during a specified time period after accounting for all capital expenditures, including expenditures for growth and maintenance capital projects. We believe that Adjusted Free Cash Flow is important to investors, lenders, commercial banks and research analysts since it reflects the amount of cash available for reducing debt, investing in additional capital projects, paying distributions, and similar matters. Our calculation of Adjusted Free Cash Flow may or may not be comparable to similarly titled measures used by other entities.
38
The GAAP measure most directly comparable to Distributable Cash Flow and Adjusted Free Cash Flow is Net Cash Provided by (Used in) Operating Activities. Distributable Cash Flow and Adjusted Free Cash Flow should not be considered alternatives to, or more meaningful than, Net Income (Loss), Operating Income (Loss), Net Cash Provided by (Used in) Operating Activities, or any other measure of liquidity presented in accordance with GAAP. Distributable Cash Flow and Adjusted Free Cash Flow have important limitations because they exclude some items that affect Net Income (Loss), Operating Income (Loss), and Net Cash Provided by (Used in) Operating Activities. Distributable Cash Flow and Adjusted Free Cash Flow may not be comparable to similarly titled measures of other companies because other companies may not calculate these non-GAAP metrics in the same manner. To compensate for these limitations, we believe that it is important to consider Net Cash Provided by (Used in) Operating Activities determined under GAAP, as well as Distributable Cash Flow and Adjusted Free Cash Flow, to evaluate our overall liquidity.
The following tables reconcile the non-GAAP financial measurements used by management to our most directly comparable GAAP measures for the three and six months ended June 30, 2026 and 2025, which represents EBITDA, Adjusted EBITDA, Distributable Cash Flow, and Adjusted Free Cash Flow:

Results of Operations
The results of operations for the three and six months ended June 30, 2026 and 2025, have been derived from our consolidated and condensed financial statements.
We evaluate segment performance on the basis of operating income, which is derived by subtracting cost of products sold, operating expenses, selling, general and administrative expenses, and depreciation and amortization expense from revenues. The following table sets forth our operating revenues and operating income by segment for the three and six months ended June 30, 2026 and 2025. The results of operations for these interim periods are not necessarily indicative of the results of operations which might be expected for the entire year.
Our consolidated and condensed results of operations are presented on a comparative basis below. There are certain items of income and expense which we do not allocate on a segment basis. These items, including interest expense and indirect selling, general and administrative expenses, are discussed following the comparative discussion of our results within each segment.

Indirect selling, general and administrative expenses decreased $0.3 million for the three months ended June 30, 2026, compared to the three months ended June 30, 2025, primarily due to lower compensation expense of $0.1
million and reduced legal and tax fees of $0.1 million.
Indirect selling, general and administrative expenses decreased $1.5 million for the six months ended June 30, 2026, compared to the six months ended June 30, 2025, primarily due to the absence of $0.8 million in transaction expenses associated with the unsuccessful merger with Martin Resource Management Corporation that were incurred in the first quarter of 2025, lower compensation expense of $0.4 million, lower professional fees of $0.2 million, and overhead allocated from Martin Resource Management of $0.1 million.
Martin Resource Management Corporation allocates to us a portion of its indirect selling, general and administrative expenses for services such as accounting, legal, treasury, clerical, billing, information technology, administration of insurance, engineering, general office expense and employee benefit plans and other general corporate overhead functions we share with Martin Resource Management Corporation retained businesses. This allocation is based on the percentage of time spent by Martin Resource Management Corporation personnel that provide such centralized services. GAAP also permits other methods for allocation of these expenses, such as basing the allocation on the percentage of revenues contributed by a segment. The allocation of these expenses between Martin Resource Management Corporation and us is subject to a number of judgments and estimates, regardless of the method used. We can provide no assurances that our method of allocation, in the past or in the future, is or will be the most accurate or appropriate method of allocation for these expenses. Other methods could result in a higher allocation of selling, general and administrative expenses to us, which would reduce our net income.
Under the Omnibus Agreement, we are required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses. The Conflicts Committee of our general partner approved the following reimbursement amounts during the three and six months ended June 30, 2026 and 2025:

Net cash used in operating activities. Net cash provided by (used in) operating activities decreased $26.5 million. The increase in net cash used in operating activities for the six months ended June 30, 2026, includes a decrease in operating results and other non-cash charges of $3.6 million, coupled with an increase in cash outflows associated with changes in working capital of $22.9 million.
Net cash used in investing activities. Net cash used in investing activities for the six months ended June 30, 2026, increased $9.0 million. An increase in cash used of $13.4 million resulted from higher payments for capital expenditures and plant turnaround costs in 2026. This was partially offset by an increase in net proceeds from the sale of property, plant and equipment of $4.4 million.
52
Net cash provided by financing activities. Net cash provided by financing activities for the six months ended June 30, 2026, increased primarily as a result of an increase in borrowings of long-term debt of $30.5 million, combined with a decrease in repayments of long-term debt of $5.0 million.
Description of Our Indebtedness
Credit Facility
At June 30, 2026, we maintained a $115.0 million credit facility that matures on November 16, 2027. As of June 30, 2026, we had $62.0 million outstanding under the credit facility and $1.6 million of outstanding irrevocable letters of credit, leaving a maximum amount available to be borrowed under our credit facility for future revolving credit borrowings and letters of credit of $51.4 million. After giving effect to our then current borrowings, letters of credit, and the financial covenants contained in our credit facility, we had the ability to borrow approximately $48.3 million in additional amounts thereunder as of June 30, 2026.
The credit facility is used for ongoing working capital needs and general partnership purposes, and to finance permitted investments, acquisitions and capital expenditures. The level of outstanding draws on our credit facility from January 1, 2026 through June 30, 2026 ranged from a low of $39.0 million to a high of $91.0 million.
The applicable margin for SOFR borrowings and alternate base rate borrowings at June 30, 2026 is 3.75% and 2.75%, respectively. The applicable margin for SOFR borrowings and alternate base rate borrowings effective July 22, 2026, is 3.75% and 2.75%, respectively.
Amendment to Credit Facility. On March 31, 2026, we entered into the Third Amendment with Royal Bank of Canada, as administrative agent and collateral agent, and the lenders party thereto, which amends the Credit Agreement.
The Third Amendment amended the Credit Agreement to, among other things:
•decrease the amount available for the Partnership to borrow under the Credit Agreement on a revolving credit basis from $130.0 million to $115.0 million; and
•adjust the financial covenants as described in more detail below:
◦require the Partnership to maintain a minimum Interest Coverage Ratio (as defined in the Credit Agreement) of at least 1.65 to 1.00 for the fiscal quarters ending March 31, 2026, June 30, 2026, September 30, 2026 and December 31, 2026 and stepping up to 1.75 to 1.00 for the fiscal quarter ending March 31, 2027 and each fiscal quarter thereafter; and
◦require the Partnership to maintain a maximum Total Leverage Ratio (as defined in the Credit Agreement) of not more than 5.50 to 1.00 for the fiscal quarters ending March 31, 2026, June 30, 2026, September 30, 2026 and December 31, 2026, stepping down to 5.30 to 1.00 for the fiscal quarter ending March 31, 2027, stepping down to 5.25 to 1.00 for the fiscal quarter ending June 30, 2027, and further stepping down to 5.00 to 1.00 for the fiscal quarter ending September 30, 2027 and each fiscal quarter thereafter.
For a description of our credit facility, see “Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Description of Our Long-Term Debt" in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 23, 2026.
2028 Notes
For a description of our 2028 Notes, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Description of Our Long-Term Debt" in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 23, 2026.
Capital Resources and Liquidity
Historically, we have generally satisfied our working capital requirements and funded our debt service obligations and capital expenditures with cash generated from operations and borrowings under our credit facility.
53
On June 30, 2026, we had cash and cash equivalents of $0.05 million and available borrowing capacity of $51.4 million under our credit facility with $62.0 million of borrowings outstanding. After giving effect to our then current borrowings, letters of credit, and the financial covenants contained in our credit facility, we had the ability to borrow approximately $48.3 million in additional amounts thereunder as of June 30, 2026.
We expect that our primary sources of liquidity to meet operating expenses, service our indebtedness, pay distributions to our unitholders and fund capital expenditures will be provided by cash flows generated by our operations, borrowings under our credit facility and access to the debt and equity capital markets. Our ability to generate cash from operations will depend upon our future operating performance, which is subject to certain risks. For a discussion of such risks, please read "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2025, filed with the SEC on February 23, 2026. In addition, due to the covenants in our credit facility, our financial and operating performance impacts the amount we are permitted to borrow under that facility.
We are in compliance with all debt covenants as of June 30, 2026, and expect to be in compliance for the next twelve months.
Interest Rate Risk
We are subject to interest rate risk on our credit facility due to the variable interest rate and may enter into interest rate swaps to reduce this variable rate risk.
Seasonality
A substantial portion of our revenues is dependent on the quantity and sales prices of products, particularly NGLs and fertilizers, which fluctuate in part based on winter and spring weather conditions. The demand for NGLs is strongest during the winter heating and blending season. The demand for fertilizers is strongest during the early spring planting season. However, our Terminalling and Storage and Transportation business segments and the molten sulfur business are typically not impacted by seasonal fluctuations and a significant portion of our net income is derived from our Terminalling and Storage, Sulfur Services and Transportation business segments. Further, extraordinary weather events, such as hurricanes, have in the past, and could in the future, impact all of our business segments.
Impact of Inflation
Inflation did not have a material impact on our results of operations for the six months ended June 30, 2026 or 2025. Inflation may increase the cost to acquire or replace property, plant and equipment. It may also increase the costs of labor and supplies. In the future, increasing energy prices for products consumed by our operations, such as diesel fuel, natural gas, chemicals, and other supplies, could adversely affect our results of operations. An increase in price of these products would increase our operating expenses which could adversely affect net income. We cannot provide assurance that we will be able to pass along increased operating expenses to our customers.
Environmental Matters
Our operations are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which these operations are conducted.
On June 15, 2024, the Partnership experienced a spill of less than 2,500 barrels of crude oil from its transfer pipeline connecting the Sandyland Terminal to the refinery in Smackover, Union County, Arkansas. The Partnership promptly coordinated with the U.S. Environmental Protection Agency (the “EPA”), Arkansas Department of Energy and Environment (the “ADEE”), and Arkansas Game and Fish Commission, dedicating the necessary resources, equipment, and personnel to expedite oil recovery and cleanup activities. In October 2024, the EPA transitioned the Partnership’s response from emergency response status to remediation status under ADEE oversight. On October 11, 2024, the ADEE notified the Partnership that documentation, observations, and data indicated the Partnership completed all remedial actions to the maximum practical extent. No further remediation is required at this time. The Partnership submitted a claim related to the spill, which was accepted by its insurance carriers, subject to a reservation of rights. The Partnership’s deductible under the applicable insurance policies total $0.5 million and such deductible expense has been recorded by the Partnership in the Consolidated and Condensed Statements of Operations. As of July 27, 2026, no fines or penalties have been assessed in relation to the spill.
We incurred no material environmental costs, liabilities or expenditures to mitigate or eliminate environmental contamination during the three months ended June 30, 2026.

| Item 3. | Quantitative and Qualitative Disclosures about Market Risk | ||||
The Partnership is exposed to commodity risk and interest rate risk in its normal business activities. The following disclosures about market risk provide an update to, and should be read in conjunction with, “Item 7A. Quantitative and Qualitative Disclosures about Market Risk” set forth in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on February 23, 2026.
Commodity Risk. The Partnership from time to time uses derivatives to manage the risk of commodity price fluctuation. Commodity risk is the adverse effect on the value of a liability or future purchase that results from a change in commodity price. We have established a hedging policy and monitor and manage the commodity market risk associated with potential commodity risk exposure. In addition, we focus on utilizing counterparties for these transactions whose financial condition is appropriate for the credit risk involved in each specific transaction.
Interest Rate Risk. We are exposed to changes in interest rates as a result of our credit facility, which had a weighted-average interest rate of 7.48% as of June 30, 2026. Based on the amount of unhedged floating rate debt owed by us on June 30, 2026, the impact of a 100 basis point increase in interest rates on this amount of debt would result in an increase in interest expense and a corresponding decrease in net income of approximately $0.6 million annually.
We are not exposed to changes in interest rates with respect to our 2028 Notes as these obligations are at a fixed rate. Based on the quoted prices for identical liabilities in markets that are not active at June 30, 2026, the estimated fair value of the 2028 Notes was $403.5 million. Market risk is estimated as the potential decrease in fair value of our long-term debt resulting from a hypothetical increase of a 100 basis point increase in interest rates. Such an increase in interest rates at June 30, 2026, would result in a $2.5 million decrease in the fair value of our 2028 Notes.
55
| Item 4. | Controls and Procedures | ||||
Evaluation of disclosure controls and procedures. In accordance with Rules 13a-15 and 15d-15 of the Exchange Act, we, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer of our general partner, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer of our general partner concluded that our disclosure controls and procedures were effective, as of the end of the period covered by this report, to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
There were no changes in our internal controls over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
56

| Item 1. | Legal Proceedings | ||||
