Net income of $3.8 million and $7.1 million for the three and six months ended June 30, 2024, respectively
Adjusted EBITDA of $31.7 million and $62.1 million for the three and six months ended June 30, 2024, respectively
Total adjusted leverage of 3.88 times as of June 30, 2024
Declares quarterly cash dividend of $0.005 per common unit

Martin Midstream Partners L.P. (NASDAQ:MMLP) ("MMLP" or the "Partnership") today announced its financial results for the second quarter of 2024.

Bob Bondurant, President and Chief Executive Officer of Martin Midstream GP LLC, the general partner of the Partnership, stated, "For the second quarter of 2024, the Partnership exceeded guidance by $0.5 million with adjusted EBITDA of $31.7 million compared to guidance of $31.2 million. Within our Transportation Services segment the land division continued to outperform projections assisted by higher than forecasted mileage along with lower maintenance expense. The marine division, however, was negatively impacted by a casualty loss reserve of $0.5 million from a bridge allision that occurred in May. The marine division also experienced lower fleet utilization this quarter as a result of both the allision and extended time of equipment in dry dock for regulatory inspection compared to forecasted duration."

"The Sulfur Services segment results were above guidance as the division benefited from strong fertilizer margins and high sulfur production from the Gulf Coast refineries. Results in the Specialty Products segment were in line with guidance as strength in our grease division offset underperformance by the packaged lubricants business. Finally, the Terminalling and Storage segment results were below guidance as a direct result of a $1.5 million casualty loss reserve related to the previously announced crude oil spill from a crude pipeline that connects our Sandyland Terminal to the Smackover refinery."

	$	19.9		$	17.3		$	31.7		$	31.8		$	31.7		$	25.5

Terminalling and storage adjusted EBITDA decreased $1.6 million, primarily reflecting the $1.5 million casualty loss reserve related to the crude oil spill from a crude pipeline that connects our Sandyland Terminal to the Smackover refinery. This casualty loss reserve was coupled with higher employee-related expenses across our divisions, offset by increased throughput in our shore-based terminals and underground NGL storage divisions.

Transportation adjusted EBITDA decreased $0.9 million, reflecting higher expenses in our marine division related to a casualty loss reserve of $0.5 million stemming from a bridge allision that occurred in May. This was coupled with lower fleet utilization as a result of both the allision and an acceleration of equipment into dry dock for regulatory inspection. Our marine division was positively impacted during the quarter by higher day rates. The land division experienced increased operating expenses, offset by increased mileage and transportation rates.

Sulfur services adjusted EBITDA increased $2.6 million, primarily reflecting increased fertilizer margins and high sulfur production from the Gulf Coast refineries.

Specialty products adjusted EBITDA, after giving effect to the exit of the butane optimization business, decreased $0.2 million, reflecting decreased margins in our NGL marketing business, offset by higher margins in our grease division.

Unallocated selling, general, and administrative expense decreased $0.1 million, reflecting reduced overhead expenses allocated from Martin Resource Management.

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 and (ii) 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), 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 and 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. 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 are 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 and adjusted free 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.

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.
