MARTIN MIDSTREAM PARTNERS REPORTS FOURTH QUARTER AND FULL YEAR 2024 FINANCIAL RESULTS AND RELEASES 2025 GUIDANCE

•Reported net loss of $8.9 million and $5.2 million for the fourth quarter and full year ended December 31, 2024, respectively, which includes $3.7 million in costs associated with the termination of the Merger Agreement

•Adjusted EBITDA of $23.3 million and $110.6 million for the fourth quarter and full year ended December 31, 2024, respectively

•On December 26, 2024, announced termination of the Merger Agreement with Martin Resource Management Corporation

•Releases 2025 Adjusted EBITDA Guidance of $109.1 million, growth capital expenditures of $9.0 million, and maintenance capital expenditures of $25.9 million

KILGORE, Texas, February 12, 2025 (BUSINESS WIRE) -- 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, 2024.

Bob Bondurant, President and Chief Executive Officer of Martin Midstream GP LLC, the general partner of the Partnership, stated, “For the fourth quarter and full year 2024 the Partnership generated Adjusted EBITDA of $23.3 million and $110.6 million, respectively, which was below our annual guidance level by approximately $5.5 million, with the variance primarily occurring in the fourth quarter. Our total debt outstanding was approximately $453.6 million as of December 31, 2024 and our liquidity was approximately $80.7 million under our revolving credit facility. We ended the year with an adjusted leverage ratio of 3.96 times based on Credit Adjusted EBITDA which includes capitalized interest and a pro-forma adjustment related to the ELSA project.”

“Speaking to our financial results by business segment, I'll begin with the Transportation division where the majority of the guidance variance occurred, as Adjusted EBITDA for the quarter was $6.5 million compared to guidance of $11.2 million. The marine business experienced much lower levels of utilization for our heated barges when compared to projections as refinery activity slowed during the quarter. Results for the land transportation business were negatively impacted early in the quarter by Hurricane Milton in Central Florida resulting in short-term challenges to our trucking operations in that market.”

“The Terminalling and Storage segment recorded Adjusted EBITDA for the quarter of $7.4 million compared to guidance of $9.4 million. During the quarter, the Smackover refinery dealt with operating performance challenges which resulted in increased expenses related to product blending. Our Specialty Terminals also saw increased maintenance costs in the quarter related to equipment repairs due to Hurricane Milton.”

“The Sulfur Services segment generated Adjusted EBITDA of $9.4 million compared to guidance of $7.6 million for the quarter as both the fertilizer and sulfur businesses beat guidance by approximately $1.0 million. The fertilizer business benefited from increased sales volumes for all product lines as compared to forecast and volumes in the sulfur business were 14% higher than our internal forecast. The segment also benefited from the revenue related to the guaranteed reservation fee, beginning this quarter as part of the improvements to our Plainview, Texas facility for the ELSA project.”

“For the quarter, the Specialty Products segment was in line with guidance as Adjusted EBITDA was $4.5 million compared to guidance of $4.6 million. The lubricants and grease businesses experienced higher margins as compared to forecast which was offset by lower than projected sales volumes for the propane business due to warm winter weather.”

“Capital expenditures for the quarter were $9.5 million with $2.9 million related to growth projects and $6.6 million for maintenance and turnaround costs. For the year 2024, growth capital expenditures totaled $25.4 million including $20.3 million for the ELSA project, and maintenance and turnaround costs were approximately $34.1 million for a total of $59.5 million.”

2025 Guidance

Commenting on 2025 full year guidance, Mr. Bondurant said, “The Partnership expects to generate Adjusted EBITDA of $109.1 million in 2025, which includes unallocated selling, general and administrative expenses of approximately $14.6 million. In addition, we anticipate capital expenditures for growth, maintenance, and plant turnaround costs to be $34.9 million. These projections result in Adjusted Free Cash Flow of approximately $18.8 million for the fiscal year.”

“The Transportation segment is projected to generate $35.4 million of Adjusted EBITDA in 2025. While we are projecting the marine business to improve year over year, results in land transportation will be negatively impacted by higher operating lease costs as we continue to recapitalize the fleet and forecasted increases in casualty insurance premiums for the trucking industry as a whole. The Terminalling and Storage segment Adjusted EBITDA forecast of $35.6 million reflects stable fee-based businesses which are favorably impacted by annual adjustments based on a price index. The Adjusted EBITDA forecast of $31.9 million for the Sulfur Services segment reflects increased earnings from the ELSA project and fertilizer business, offset by an anticipated decrease in margin per ton on the pure sulfur side. The Specialty Products segment Adjusted EBITDA forecast of $20.8 reflects anticipated stability in each business with a slight increase in results for both the grease and propane businesses.”

“Finally, as we considered the future of MMLP, including through conversations over the last year with our investors and advisors, it became clear internally that our focus should remain on improving the balance sheet through debt reduction and identifying opportunities to improve operating results that will strengthen the Partnership’s position when the time arrives to refinance our outstanding notes due in 2028. As we look forward, I want to thank our employees for their dedication and commitment to serving our customers, suppliers, and communities where we live and operate.”

More detailed 2025 Financial Guidance is provided as an attachment included in the Current Report on Form 8-K to which this press release is included.

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 as the adjustments required to reconcile forward-looking non-GAAP measures cannot be predicted with a reasonable degree of 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.

MMLP does not intend at this time to provide financial guidance beyond 2025.

Termination of the Merger Agreement

As previously disclosed, on December 26, 2024, MMLP announced the termination of the previously announced Agreement and Plan of Merger (the “Merger Agreement”), dated October 3, 2024, with Martin Resource Management Corporation (“MRMC”), pursuant to which MRMC would have acquired all of the outstanding common units of MMLP not already owned by MRMC and its subsidiaries (the “Merger”). The Merger Agreement was terminated by the mutual written consent of MRMC and MMLP (with the approval of the Conflicts Committee of the Board of Directors of Martin Midstream GP LLC pursuant to the terms of the Merger Agreement. MMLP will continue to operate as a standalone publicly traded company.

$ 17.2 $ 29.2 $ 29.2

All values are in US Dollars.

Transportation Adjusted EBITDA decreased by $5.5 million. In our land division, Adjusted EBITDA declined by $4.3 million, primarily due to increased operating expenses. Additionally, lower miles contributed to a decrease in freight revenue. In our marine division, Adjusted EBITDA decreased by $1.2 million, driven by lower inland utilization and higher employee-related expenses. These impacts were partially offset by higher inland and offshore day rates, as well as lower operating expenses.

Terminalling and Storage Adjusted EBITDA decreased by $1.6 million. At our Smackover refinery, Adjusted EBITDA declined by $0.9 million, primarily due to higher operating expenses. In our specialty terminals division, Adjusted EBITDA fell by $1.4 million, driven by increased operating expenses. These declines were partially offset by a $0.5 million increase in Adjusted EBITDA in our shore-based terminals division, primarily due to higher fuel throughput. In our underground NGL storage division, Adjusted EBITDA increased by $0.1 million as lower operating expenses were partially offset by decreased throughput revenue.

Sulfur Services Adjusted EBITDA increased by $2.0 million. In our fertilizer division, Adjusted EBITDA rose by $1.2 million, driven by reservation fees from our new DSM Semichem joint venture. Additionally, we experienced export sales activity in Q4 2024, which did not occur in Q4 2023. In our pure sulfur business, Adjusted EBITDA increased by $0.9 million due to higher margins and volume-driven increased to operating fees. These increases were partially offset by a $0.1 million decline in our sulfur prilling business, primarily due to higher operating expenses.

Specialty Products Adjusted EBITDA decreased by $0.4 million. In our lubricants division, Adjusted EBITDA increased by $0.2 million, driven by higher margins, partially offset by lower volumes. In our grease division, Adjusted EBITDA decreased by $0.1 million, primarily due to higher employee-related expenses and lower margins. In our propane division, Adjusted EBITDA declined by $0.3 million, primarily due to lower volumes and margins. In our NGL division, Adjusted EBITDA remained steady at $0.3 million, reflecting consistent volumes and margins.

Unallocated selling, general, and administrative expense increased by $0.3 million, primarily due to higher insurance-related costs. This increase was partially offset by lower professional fees and a reduced overhead allocation from Martin Resource Management Corporation.

All values are in US Dollars.

Transportation Adjusted EBITDA decreased by $4.3 million. In our land division, Adjusted EBITDA declined by $6.5 million, primarily due to higher operating expenses and a slight decrease in transportation rates, partially offset by increased freight revenue driven by higher miles. In our marine division, Adjusted EBITDA increased by $2.2 million, reflecting higher inland and offshore transportation rates and lower insurance-related costs. These increases were partially offset by lower inland and offshore utilization due to downtime from regulatory inspections, as well as higher employee-related expenses.

Terminalling and Storage Adjusted EBITDA decreased by $3.1 million. In our shore-based terminals division, Adjusted EBITDA increased by $2.5 million, primarily due to higher fuel throughput and space rental revenue. In our specialty terminals division, Adjusted EBITDA declined by $2.2 million, driven by increased operating expenses, partially offset by higher storage, throughput, and miscellaneous service revenue. At our Smackover refinery, Adjusted EBITDA decreased by $3.4 million, primarily due to higher insurance-related and other operating expenses. In our underground NGL storage division, Adjusted EBITDA remained steady at $1.6 million.

Sulfur Services Adjusted EBITDA increased by $2.7 million. In our fertilizer division, Adjusted EBITDA rose by $1.6 million, driven by reservation fees from our new DSM Semichem joint venture, increased margins, and export sales activity in 2024, compared to no export activity in 2023. These increases were partially offset by lower sales volumes. In our sulfur division, Adjusted EBITDA increased by $1.1 million. Within this division, our pure sulfur business saw a $1.1 million rise in Adjusted EBITDA due to higher margins, increased service revenue from higher contractual rates, and lower utilities expenses. In our sulfur prilling business, Adjusted EBITDA rose by $0.1 million, primarily due to a volume-driven increase in operating fees, partially offset by higher operating expenses.

Specialty Products Adjusted EBITDA increased $12.5 million. Specialty products Credit Adjusted EBITDA, which excludes 2023 results from the previously exited butane optimization business, declined by $2.6 million. In our lubricants division, Adjusted EBITDA fell by $1.9 million, driven by lower volume and margins, along with higher employee-related expenses. In our grease division, Adjusted EBITDA decreased by $0.3 million, primarily due to higher employee-related expenses. In our propane division, Adjusted EBITDA remained steady at $2.1 million, while in our NGL division, Adjusted EBITDA declined by $0.3 million due to lower margins.

Unallocated selling, general, and administrative expense decreased by $0.2 million, reflecting lower professional fees and a reduction in the overhead allocation from Martin Resource Management Corporation, partially offset by increased insurance claims expense.

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, and (vii) 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.

EBITDA, 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, and transaction costs associated with business combination, merger, and divestiture activities. 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 excluding net income (loss) and the lower of cost or net realizable value and other non-cash adjustments associated with the butane optimization business, which we exited during the second quarter of 2023. 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 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.

Page 6 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, and (vii) 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 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.
