MARTIN MIDSTREAM PARTNERS REPORTS SECOND QUARTER 2022 FINANCIAL RESULTS, INCREASES ANNUAL GUIDANCE AND DECLARES QUARTERLY CASH DISTRIBUTION

▪Announces increased 2022 financial guidance

▪Reported net income of $6.6 million and $18.1 million for the three and six months ended June 30, 2022, respectively

▪Reported adjusted EBITDA of $38.3 million and $78.3 million for the three and six months ended June 30, 2022, respectively

KILGORE, Texas, July 20, 2022 (GLOBE NEWSWIRE) -- Martin Midstream Partners L.P. (Nasdaq:MMLP) ("MMLP" or the "Partnership") today announced its financial results for the second quarter of 2022.

Bob Bondurant, President and Chief Executive Officer of Martin Midstream GP LLC, the general partner of the Partnership stated, “The Partnership experienced another outstanding quarter with elevated demand for our land transportation assets, and robust margins in our lubricants and fertilizer businesses. Overall, each of our four business segments performed above expectations beating the high range of guidance for the quarter by $13 million. We now expect the current refinery utilization levels to remain strong through year end which will bring continued solid demand for our diversified products and services. Based on this expectation, we are raising our 2022 adjusted EBITDA guidance range to $126 - $135 million.

“The current operating environment for our business segments has provided the opportunity for consistent leverage reduction as year over year we have reduced outstanding debt and improved financial results. As a result, on June 30, 2022, the Partnership’s adjusted leverage ratio was 3.46 times compared to 3.87 times at March 31, 2022. While that is an important milestone, our current guidance indicates that the Partnership will exit 2022 with approximately the same adjusted leverage ratio announced today, as higher commodity prices continue to increase our working capital needs specifically within the natural gas liquids segment. Our focus will remain on conservative capital management to meet the goal of a sustained leverage ratio below 3.75 times.”

QUALIFIED NOTICE TO NOMINEES

This release serves as qualified notice to nominees as provided for under Treasury Regulation Section 1.1446-4(b)(4) and (d). Please note that 100 percent of the Partnership's distributions to foreign investors are attributable to income that is effectively connected with a United States trade or business. Accordingly, all of the Partnership's distributions to foreign investors are subject to federal income tax withholding at the highest effective tax rate for individuals or corporations, as applicable. Nominees, and not the Partnership, are treated as withholding agents responsible for withholding on the distributions received by them on behalf of foreign investors.

RESULTS OF OPERATIONS

The Partnership had net income for the three months ended June 30, 2022 of $6.6 million, or $0.17 per limited partner unit. The Partnership had a net loss for the three months ended June 30, 2021 of $6.6 million, a loss of $0.17 per limited partner unit. Adjusted EBITDA for the three months ended June 30, 2022 was $38.3 million compared to $22.5 million for the three months ended June 30, 2021. Net cash provided by (used in) operating activities for the three months ended June 30, 2022 was ($2.5) million, compared to $2.2 million for the three months ended June 30, 2021. Distributable cash flow for the three months ended June 30, 2022 was $22.3 million compared to $7.3 million for the three months ended June 30, 2021.

Revenues for the three months ended June 30, 2022 were $267.0 million compared to $184.3 million for the three months ended June 30, 2021.

The Partnership had net income for the six months ended June 30, 2022 of $18.1 million, or $0.46 per limited partner unit. The Partnership had a net loss for the six months ended June 30, 2021 of $4.1 million, a loss of $0.10 per limited partner unit. Adjusted EBITDA for the six months ended June 30, 2022 was $78.3 million compared to $53.4 million for the six months ended June 30, 2021. Net cash provided by operating activities for the six months ended June 30, 2022 was $28.5 million, compared to $6.1 million for the six months ended June 30, 2021. Distributable cash flow for the six months ended June 30, 2022 was $38.5 million compared to $15.6 million for the six months ended June 30, 2021.

Revenues for the six months ended June 30, 2022 were $546.2 million compared to $385.3million for the six months ended June 30, 2021.

EBITDA, adjusted EBITDA, distributable cash flow and adjusted free cash flow are non-GAAP financial measures which are explained in greater detail below under the heading "Use of Non-GAAP Financial Information." The Partnership has also included below a table entitled "Reconciliation of EBITDA, Adjusted EBITDA, Distributable Cash Flow and Adjusted Free Cash Flow" in order to show the components of these non-GAAP financial measures and their reconciliation to the most comparable GAAP measurement.

An attachment included in the Current Report on Form 8-K to which this announcement is included, contains a comparison of the Partnership’s adjusted EBITDA for the second quarter 2022 to the Partnership's adjusted EBITDA for the second quarter 2021.

2022 REVISED FINANCIAL GUIDANCE

The Partnership now expects to generate adjusted EBITDA between $126 million and $135 million for full-year 2022, compared to the previously revised adjusted EBITDA guidance of between $110 million and $120 million. This increased guidance reflects our expectation that current refinery utilization levels will remain consistent through year-end 2022 which will bring continued solid demand for our diversified products and services.

Distributable cash flow is now expected to be between $53 million and $62 million for full-year 2022, compared to the revised distributable cash flow guidance of between $37 million and $47 million. Adjusted free cash flow is now expected to be between $44 million and $53 million, compared to the revised adjusted free cash flow guidance of between $29 million and $39 million.

MMLP does not intend at this time to provide financial guidance beyond 2022.

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.

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 current and potential impacts of the COVID-19 pandemic generally (including variants of the virus), on an industry-specific basis, and on the Partnership’s specific operations and business, (ii) the effects of the continued volatility of commodity prices and the related macroeconomic and political environment, and (iii) 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 the Partnership's management in assessing its business, it uses 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"). The Partnership's management uses a variety of financial and operational measurements other than its financial statements prepared in accordance with United States Generally Accepted Accounting Principles ("GAAP") to analyze its 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. The Partnership defines 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 the Partnership's management and by external users of its financial statements, such as investors, commercial banks, research analysts, and others, to assess:

•the financial performance of the Partnership's assets without regard to financing methods, capital structure, or historical cost basis;

•the ability of the Partnership's assets to generate cash sufficient to pay interest costs, support its indebtedness, and make cash distributions to its unitholders; and

•its 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 the Partnership has borrowed money to finance its operations, interest expense is a necessary element of its costs and its ability to generate cash available for distribution. Because the Partnership has capital assets, depreciation and amortization are also necessary elements of its costs. Therefore, any measures that exclude these elements have material limitations. To compensate for these limitations, the Partnership believes 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 its overall performance.

Distributable Cash Flow. The Partnership defines 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 the Partnership's management and by external users of its financial statements, such as investors, commercial banks and research analysts, to compare basic cash flows generated by us to the cash distributions it expects to pay unitholders. Distributable cash flow is also an important financial measure for the Partnership's unitholders since it serves as an indicator of its success in providing a cash return on investment. Specifically, this financial measure indicates to investors whether or not the Partnership is generating cash flow at a level that can sustain or support an increase in its 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. The Partnership defines 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 the Partnership's management and by external users of its 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. The Partnership believes 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. The Partnership's 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, the Partnership believes 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 its overall liquidity.
