KILGORE, Texas, October 16, 2024 (BUSINESS WIRE) -- Martin Midstream Partners L.P. (Nasdaq: MMLP) (“MMLP” or the “Partnership”) today announced its financial results for the third quarter of 2024.

Bob Bondurant, President and Chief Executive Officer of Martin Midstream GP LLC, the general partner of the Partnership (the "General Partner"), stated, “I am pleased with the Partnership’s third quarter financial results of $25.1 million in adjusted EBITDA despite the slight miss of $1.3 million when compared to guidance targeting $26.4 million in adjusted EBITDA. During the quarter, the Partnership recorded an additional $1.4 million in expense, when compared to guidance, related to our long-term incentive plans which are tied to the fair market value of our common units. With the exception of the Specialty Products division, financial results were above guidance in all remaining segments when allowing for this additional cost.”

“As we look to the coming months leading up to the potential merger with MRMC, our team will remain dedicated to the execution of our long-term strategy; and focused on enhancing the value we provide to our customers, suppliers, and the communities where we live and where our businesses operate.”

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 third quarter 2024 to the Partnership's adjusted EBITDA guidance for the third quarter 2024.

QUARTERLY CASH DISTRIBUTION

The Partnership has declared a quarterly cash distribution of $0.005 per unit for the quarter ended September 30, 2024. The distribution is payable on November 14, 2024, to common unitholders of record as of the close of business on November 7, 2024. The ex-dividend date for the cash distribution is November 7, 2024.

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.

MERGER AGREEMENT WITH MARTIN RESOURCE MANAGEMENT CORPORATION

On October 3, 2024, the Partnership announced that it has entered into a definitive agreement and plan of merger (“Merger Agreement”) pursuant to which MRMC would acquire all of the outstanding common units of MMLP not already owned by MRMC and its subsidiaries (the “Public Common Units”). The Merger Agreement follows the offer made by MRMC in May 2024 to acquire the Public Common Units.

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) the ability of the parties to consummate the transactions contemplated by the Merger Agreement in the anticipated timeframe or at all, including MRMC’s ability to fund the aggregate merger consideration; risks related to the satisfaction or waiver of the conditions to closing the transaction in the anticipated timeframe or at all; risks related to obtaining the requisite regulatory approval and Partnership unitholder approval; disruption from the transaction making it more difficult to maintain business and operational relationships; significant transaction costs associated with the transaction; and the risk of litigation and/or regulatory actions related to the transaction, (iii) uncertainties relating to the Partnership’s future cash flows and operations, (iv) the Partnership’s ability to pay future distributions, (v) future market conditions, (vi) current and future governmental regulation, (vii) future taxation, 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.

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. 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.
