MARTIN MIDSTREAM PARTNERS REPORTS SECOND QUARTER 2026 FINANCIAL RESULTS AND DECLARES QUARTERLY CASH DISTRIBUTION

•Net income of $2.6 million and net loss of $4.1 million for the three and six months ended June 30, 2026, respectively

•Adjusted EBITDA of $27.9 million and $48.7 million for the three and six months ended June 30, 2026, respectively

•Declares quarterly cash dividend of $0.005 per common unit

•Maintains full year Adjusted EBITDA guidance of $90.0 million

KILGORE, Texas, July 22, 2026 (BUSINESS WIRE) -- Martin Midstream Partners L.P. (Nasdaq: MMLP) (“MMLP” or the “Partnership”) today announced its financial results for the second quarter of 2026.

Bob Bondurant, President and Chief Executive Officer of Martin Midstream GP LLC, the general partner of the Partnership, stated, “For the second quarter of 2026, the Partnership generated Adjusted EBITDA of $27.9 million, ahead of our internal expectations for the quarter and modestly above the $27.1 million generated in the second quarter of 2025. Outperformance across three of our four operating segments, combined with meaningful contributions from our pure sulfur business, more than offset continued weakness in our fertilizer division. Our first-half results keep us on pace to achieve our full-year 2026 Adjusted EBITDA guidance of $90.0 million.”

“Our Terminalling and Storage segment delivered a strong quarter, with results exceeding our internal projections on higher than forecasted throughput revenue.”

“Our Specialty Products segment also outperformed for the quarter, delivering results above our internal estimates, as continued momentum in our lubricants business more than offset softness in the grease business unit.”

“In our Transportation Services segment, results exceeded our internal forecast for the quarter. Our land transportation business delivered solid results and our marine equipment performed as anticipated. With regulatory inspections mostly completed, we expect our inland and offshore equipment utilization to return to projected operating percentages. While driver availability across the trucking industry remains challenged, we continue to focus on exceptional service and long-term customer relationships to protect the profitability of our land transportation business.”

“In our Sulfur Services segment, results fell short of our internal plan, driven entirely by the fertilizer division, where compressed margins reflected weak grower economics and elevated raw material input costs. Favorable performance from our pure sulfur business partially offset this shortfall. We expect the fertilizer weakness to persist through the balance of the year, but we anticipate our pure sulfur business will continue to help offset this pressure. Separately, the DSM Semichem joint venture reached a milestone this quarter, generating its first sales. While not financially material to 2026, qualification work with semiconductor fabrication customers is progressing well and supports our expectation of stronger sales activity in 2027.”

“As of June 30, 2026, total debt outstanding was approximately $462.0 million, liquidity under our revolving credit facility was approximately $48.3 million, and our leverage ratio was 4.96 times based on Credit Adjusted EBITDA. As forecasted, we spent the majority of our projected 2026 capital expenditures in the first six months of the year completing the Smackover Refinery turnaround as well as the bulk of the required regulatory inspections of our marine fleet.”

$ 19.3  $ 14.9  $ 27.9  $ 27.1

Transportation Adjusted EBITDA decreased by $0.5 million. In our land transportation division, Adjusted EBITDA remained consistent. In the marine division, Adjusted EBITDA decreased $0.5 million. Adjusted EBITDA in our offshore division declined $1.0 million as a result of downtime associated with regulatory inspections. Adjusted EBITDA in our inland division increased $0.4 million on higher day rates and utilization.

Terminalling and Storage Adjusted EBITDA increased by $1.1 million. In the underground NGL storage division, Adjusted EBITDA increased $1.1 million on higher throughput volumes. Adjusted EBITDA in our specialty terminals division increased $0.1 million on higher throughput and storage revenue. Our shore-based terminals division remained generally consistent. At our Smackover refinery, Adjusted EBITDA decreased $0.2 million as a result of higher expenses.

Sulfur Services Adjusted EBITDA decreased by $1.0 million. In the fertilizer division, Adjusted EBITDA decreased $4.6 million, driven by margin compression as a result of reduced demand, as higher input costs (principally for sulfur and ammonia) raised fertilizer prices, negatively impacting farmer affordability. In the pure sulfur business, Adjusted EBITDA increased $3.1 million, primarily reflecting increased margins resulting from higher prices. In the sulfur prilling business, Adjusted EBITDA increased $0.3 million on higher reservation fees and volumes. Adjusted EBITDA from our ELSA joint venture increased $0.2 million, as deliveries began late in the first quarter of 2026.

Specialty Products Adjusted EBITDA increased by $1.0 million. In the lubricants division, Adjusted EBITDA increased $1.4 million on higher sales volume. In the grease division, Adjusted EBITDA decreased $0.7 million, reflecting lower volume and margins. Adjusted EBITDA in our propane division increased $0.1 million on higher margins, and our natural gasoline division increased $0.1 million on higher volumes.

Indirect selling, general, and administrative expenses decreased by $0.3 million, primarily due to lower compensation expense, combined with lower legal and tax fees.

QUARTERLY CASH DISTRIBUTION

The Partnership has declared a quarterly cash distribution of $0.005 per unit for the quarter ended June 30, 2026. The distribution is payable on August 14, 2026, to common unitholders of record as of the close of business on August 7, 2026. The ex-dividend date for the cash distribution is August 7, 2026.

Qualified Notice to Nominees

This release is intended to serve as qualified notice under Treasury Regulation Section 1.1446-4(b)(4) and (d). Brokers and nominees should treat one hundred percent (100%) of MMLP’s distributions to non-U.S. investors as being attributable to income that is effectively connected with a United States trade or business. Accordingly, MMLP’s distributions to non-U.S. investors are subject to federal income tax withholding at the highest applicable effective tax rate. For purposes of Treasury Regulation section 1.1446(f)-4(c)(2)(iii), brokers and nominees should treat one hundred percent (100%) of the distributions as being in excess of cumulative net income for purposes of determining the amount to withhold. Nominees, and not Martin Midstream Partners L.P., are treated as withholding agents responsible for any necessary withholding on amounts received by them on behalf of foreign investors.

Forward-Looking Statements

Statements about the Partnership’s outlook and all other statements in this release other than historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements and all references to financial estimates rely on a number of assumptions concerning future events and are subject to a number of uncertainties, including (i) the effects of the continued volatility of commodity prices and the related macroeconomic and political environment, (ii) uncertainties relating to the Partnership’s future cash flows and operations, (iii) the Partnership’s ability to pay future distributions, (iv) future market conditions, (v) current and future governmental regulation, (vi) future taxation, (vii) our expectation around the achievement of the amounts reflected in our guidance, and (viii) other factors, many of which are outside its control, which could cause actual results to differ materially from such statements. While the Partnership believes that the assumptions concerning future events are reasonable, it cautions that there are inherent difficulties in anticipating or predicting certain important factors. A discussion of these factors, including risks and uncertainties, is set forth in the Partnership’s annual and quarterly reports filed from time to time with the Securities and Exchange Commission (the “SEC”). The Partnership disclaims any intention or obligation to revise any forward-looking statements, including financial estimates, whether as a result of new information, future events, or otherwise except where required to do so by law.

Use of Non-GAAP Financial Information

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), Credit 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 and Credit 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.

We define Credit Adjusted EBITDA as Adjusted EBITDA plus pro forma adjustments associated with business combinations or material projects and capitalized interest. Credit 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 provide additional information regarding the calculation of, and compliance with, certain financial covenants in the Partnership’s Fourth Amended and Restated Credit Agreement.

The GAAP measures most directly comparable to Adjusted EBITDA and Credit Adjusted EBITDA are Net Income (Loss) and Net Cash Provided by (Used In) Operating Activities. Adjusted EBITDA and Credit 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 and Credit 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.

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.

Disclaimers Page 7 Use of Non-GAAP Financial Measures Forward Looking Statements This presentation includes certain non-GAAP financial measures such as Adjusted EBITDA. These non-GAAP financial measures are not meant to be considered in isolation or as a substitute for results prepared in accordance with accounting principles generally accepted in the United States (GAAP). A reconciliation of non-GAAP financial measures included in this presentation to the most directly comparable financial measures calculated and presented in accordance with GAAP is set forth in the Appendix of this presentation or on our web site at www.MMLP.com. MMLP’s management believes that these non-GAAP financial measures may provide useful information to investors regarding MMLP’s financial condition and results of operations as they provide another measure of the profitability and ability to service its debt and are considered important measures by financial analysts covering MMLP and its peers. The Partnership has not provided comparable GAAP financial information on a forward-looking basis because it would require the Partnership to create estimated ranges on a GAAP basis, which would entail unreasonable effort. Adjustments required to reconcile forward-looking non-GAAP measures cannot be predicted with reasonable certainty but may include, among others, costs related to debt amendments and unusual charges, expenses and gains. Some or all of those adjustments could be significant. Statements about the Partnership’s outlook and all other statements in this release other than historical facts are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements and all references to financial estimates rely on a number of assumptions concerning future events and are subject to a number of uncertainties, including (i) the effects of the continued volatility of commodity prices and the related macroeconomic and political environment, (ii) uncertainties relating to the Partnership’s future cash flows and operations, (iii) the Partnership’s ability to pay future distributions, (iv) future market conditions, (v) current and future governmental regulation, (vi) future taxation, (vii) our expectation around the achievement of the amounts reflected in our guidance, and (viii) other factors, many of which are outside its control, which could cause actual results to differ materially from such statements. While the Partnership believes that the assumptions concerning future events are reasonable, it cautions that there are inherent difficulties in anticipating or predicting certain important factors. A discussion of these factors, including risks and uncertainties, is set forth in the Partnership’s annual and quarterly reports filed from time to time with the Securities and Exchange Commission (the “SEC”). The Partnership disclaims any intention or obligation to revise any forward- looking statements, including financial estimates, whether as a result of new information, future events, or otherwise except where required to do so by law.
