Martin Midstream Partners L.P. (NASDAQ:MMLP) ("MMLP" or the "Partnership") today announced its financial results for the fourth quarter and full year ended December 31, 2025.

Bob Bondurant, President and Chief Executive Officer of Martin Midstream GP LLC, the general partner of the Partnership, stated, "In 2025, the Partnership demonstrated the resilience of our diversified asset base, generating Adjusted EBITDA of $99.0 million for the full year and $24.8 million in the fourth quarter. While our GAAP net loss reflects non-cash items and specific segment headwinds, our focus remained on balance sheet discipline. We ended the year with total debt outstanding of approximately $439.1 million, liquidity of $31.4 million under our revolving credit facility, and an adjusted leverage ratio of 4.43 times based on Credit Adjusted EBITDA."

"Our 2025 results within the Terminalling and Storage segment, our pure sulfur services business, and our land transportation business delivered stable performance, underscoring the durability of our fixed-fee contracts within these businesses. This stability was partially offset by a decline in marine utilization during the third quarter, a softer fertilizer market in the fourth quarter, and headwinds in our grease business throughout the year."

2026 Guidance

"Turning to 2026 full-year guidance, Mr. Bondurant said, "The Partnership anticipates generating Adjusted EBITDA of $96.5 million in 2026, with capital expenditures for growth, maintenance, and plant turnaround activities expected to total $36.5 million, compared to $31.6 million in 2025. Capital spending is elevated in 2026, driven primarily by scheduled refinery turnaround activity. This higher spending is expected to result in adjusted free cash flow of approximately $5.8 million for the fiscal year."

"The Terminalling and Storage segment Adjusted EBITDA forecast of $31.6 million reflects normalized operating performance."

"The Transportation segment is projected to generate $31.4 million of Adjusted EBITDA in 2026, similar to 2025 performance. Land transportation results are expected to track relatively flat year over year. The inland marine division is expected to improve versus 2025, while the offshore division is projected to experience reduced utilization due to planned downtime from regulatory inspections."

"The Sulfur Services segment is projected to deliver Adjusted EBITDA of $30.3 million in 2026, consistent with prior-year results. The fertilizer market is expected to remain compressed due to rising sulfur input costs. Cash flow contributions from ELSA are expected to hold steady with the prior year, reflecting ongoing reservation fee revenue."

"The Specialty Products segment is projected to generate $17.6 million of Adjusted EBITDA in 2026. The lubricants and NGL businesses are expected to track in line with the prior year, while the grease business is projected to improve modestly in the back half of the year driven by higher sales volumes."

Transportation Adjusted EBITDA increased by $2.4 million. In our marine division, Adjusted EBITDA increased by $2.1 million, reflecting higher inland utilization and offshore day rates, combined with lower employee-related expenses. These impacts were partially offset by lower inland day rates. In our land division, Adjusted EBITDA increased by $0.3 million, reflecting increased service revenue and transportation rates, combined with lower operating expenses. These impacts were partially offset by fewer miles.

Terminalling and Storage Adjusted EBITDA increased by $2.7 million.

In our underground NGL storage division, Adjusted EBITDA increased by $0.6 million, driven by higher storage revenue, partially offset by increased operating expenses. In our specialty terminals division, Adjusted EBITDA rose by $0.3 million, reflecting decreased operating expenses. In our shore-based terminals division, Adjusted EBITDA increased by $0.2 million, reflecting a reduction in operating expenses.

Sulfur Services Adjusted EBITDA decreased by $3.7 million. In our fertilizer division, Adjusted EBITDA declined by $4.1 million, driven by lower margins.

Unallocated selling, general, and administrative expense decreased by $0.9 million, reflecting lower insurance-related costs.

Transportation Adjusted EBITDA decreased by $11.7 million. In our land division, Adjusted EBITDA declined by $7.6 million, reflecting decreased freight revenue as a result of lower miles, partially offset by increased transportation rates. In our marine division, Adjusted EBITDA decreased by $4.1 million, reflecting lower inland transportation rates and utilization, offset by lower operating cost and higher offshore transportation rates and utilization.

Terminalling and Storage Adjusted EBITDA increased by $3.1 million. At our Smackover refinery, Adjusted EBITDA increased by $2.5 million, reflecting lower insurance-related costs combined with higher throughput and reservation fees, partially offset by higher operating expenses. In our underground NGL storage division, Adjusted EBITDA increased by $1.1 million, driven by higher storage revenue, partially offset by increased operating expenses. In our shore-based terminals division, Adjusted EBITDA increased by $0.1 million, reflecting lower operating expenses, partially offset by a decrease in service revenue.

In our sulfur division, Adjusted EBITDA decreased by $0.7 million. Within this division, our pure sulfur business saw a $0.4 million decline in Adjusted EBITDA due to higher operating expenses and slightly lower margins.

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 Third 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, plus changes in operating assets and liabilities which (provided) used cash, transaction costs associated with business combination, merger, and divestiture activities, and non-cash contractual revenue deferral adjustments, 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.
