## Management's discussion and analysis

As filed, 63,097 characters.

You should read the following discussion of our financial condition and results of operations in conjunction with the consolidated and condensed financial statements and the notes thereto included elsewhere in this quarterly report.

### Overview

We are a publicly traded limited partnership with a diverse set of operations focused primarily in the Gulf Coast region of the U.S. Our four primary business lines include:

- Terminalling, processing, and storage services for petroleum products and by-products;
- Land and marine transportation services for petroleum products and by-products, chemicals, and specialty products;
- Sulfur and sulfur-based products processing, manufacturing, marketing, and distribution; and
- Marketing, distribution, and transportation services for natural gas liquids and blending and packaging services for specialty lubricants and grease.

The petroleum products and by-products we collect, transport, store and market are produced primarily by major and independent oil and gas companies who often turn to third parties, such as us, for the transportation and disposition of these products. In addition to these major and independent oil and gas companies, our primary customers include independent refiners, large chemical companies, and other wholesale purchasers of these products. We operate primarily in the Gulf Coast region of the U.S. This region is a major hub for petroleum refining, natural gas gathering and processing, and support services for the exploration and production industry.

We were formed in 2002 by Martin Resource Management Corporation, a privately-held company whose initial predecessor was incorporated in 1951 as a supplier of products and services to drilling rig contractors. Since then, Martin Resource Management Corporation has expanded its operations through acquisitions and internal expansion initiatives as its management identified and capitalized on the needs of producers and purchasers of petroleum products and by-products and other bulk liquids. Martin Resource Management Corporation is an important supplier and customer of ours. As of June 30, 2024, Martin Resource Management Corporation owned 15.7% of our total outstanding common limited partner units and 100% of MMGP Holdings, LLC ("Holdings"), which is the sole member of Martin Midstream GP LLC ("MMGP"), our general partner. MMGP owns a 2.0% general partner interest in us.

We entered into the Omnibus Agreement that governs, among other things, potential competition and indemnification obligations among the parties to the agreement, related party transactions, the provision of general administration and support services by Martin Resource Management Corporation and our use of certain of Martin Resource Management Corporation’s trade names and trademarks. Under the terms of the Omnibus Agreement, the employees of Martin Resource Management Corporation are responsible for conducting our business and operating our assets.

Martin Resource Management Corporation has operated our business since our inception in 2002. Martin Resource Management Corporation began operating our NGL business in the 1950s and our sulfur business in the 1960s. It began our land transportation business in the early 1980s and our marine transportation business in the late 1980s. It entered into our fertilizer and terminalling and storage businesses in the early 1990s.

### Significant Recent Developments

*MMLP Receives Buyout Offer from Martin Resource Management.* On May 24, 2024, we announced that Martin Resource Management filed an amendment to its Schedule 13D (the “13D Amendment”) with the SEC. The 13D Amendment disclosed that Martin Resource Management submitted a non-binding proposal to the Conflicts Committee, pursuant to which Martin Resource Management would acquire all of the outstanding Common Units of the Partnership not already owned by Martin Resource Management or its subsidiaries for a cash purchase price of $3.05 per Common Unit. The other terms of such proposal are set forth in the 13D Amendment.

The proposed transaction is subject to several contingencies, including the approval of the Conflicts Committee and the Board of Directors, the approval by the Partnership’s unitholders, and the satisfaction of any conditions to the consummation of a transaction set forth in any definitive agreement concerning the transaction. There can be no assurance that definitive documentation will be executed or that any transaction will materialize on the terms described above or at all.

*Galveston Bridge Allision.* During May 2024, we experienced a casualty loss of $0.5 million that represents two separate insurance deductibles under our marine transportation protection and indemnity coverage policy and our hull coverage policy stemming from a bridge allision in Galveston, Texas.

*Electronic Level Sulfuric Acid Joint Venture.* On October 19, 2022, Martin ELSA Investment LLC, our affiliate, entered into definitive agreements with Samsung C&T America, Inc. and Dongjin USA, Inc., an affiliate of Dongjin Semichem Co., Ltd., to form DSM Semichem LLC (“DSM”). DSM will produce and distribute electronic level sulfuric acid (“ELSA”). By leveraging our existing assets located in Plainview, Texas and installing additional facilities (the “ELSA Facility”) as required, DSM will produce ELSA that meets the strict quality standards required by the recent advances in semiconductor manufacturing. In addition to owning a 10% non-controlling interest in DSM, we will be the exclusive provider of feedstock to the ELSA Facility. We, through our affiliate MTI, will also provide land transportation services for the ELSA produced by DSM. We expect to fund approximately $27.0 million in aggregate capital expenditures in connection with this joint venture. On April 1, 2024, we contributed $6.5 million to DSM, which represents the cash contribution required pursuant to DSM's limited liability agreement for our 10% non-controlling interest. As of June 30, 2024, we have funded approximately $23.9 million toward ELSA related project costs.

### Subsequent Events

*Quarterly Distribution.* On July 17, 2024, we declared a quarterly cash distribution of $0.005 per common unit for the second quarter of 2024, or $0.020 per common unit on an annualized basis, which will be paid on August 14, 2024, to unitholders of record as of August 7, 2024.

### Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations are based on the historical consolidated and condensed financial statements included elsewhere herein. We prepared these financial statements in conformity with U.S. GAAP. The preparation of these financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods. We base our estimates on historical experience and on various other assumptions we believe to be reasonable under the circumstances. We routinely evaluate these estimates, utilizing historical experience, consultation with experts and other methods we consider reasonable in the particular circumstances. Our results may differ from these estimates, and any effects on our business, financial position or results of operations resulting from revisions to these estimates are recorded in the period in which the facts that give rise to the revision become known. Changes in these estimates could materially affect our financial position, results of operations or cash flows. See the "Critical Accounting Policies and Estimates" section in "Management's Discussion and Analysis of Financial Condition and Results of Operations" and Note 2, "Significant Accounting Policies" in Notes to Consolidated Financial Statements included within our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 21, 2024.

### Approval and Review of Related Party Transactions

If we contemplate entering into a transaction, other than a routine or in the ordinary course of business transaction, in which a related person will have a direct or indirect material interest, the proposed transaction is submitted for consideration to the board of directors of our general partner or to our management, as appropriate. If the board of directors of our general partner is involved in the approval process, it determines whether to refer the matter to the Conflicts Committee of our general partner's board of directors, as constituted under our limited partnership agreement. If a matter is referred to the Conflicts Committee, the Conflicts Committee obtains information regarding the proposed transaction from management and determines whether to engage independent legal counsel or an independent financial advisor to advise the members of the committee regarding the transaction. If the Conflicts Committee retains such counsel or financial advisor, it considers such advice and, in the case of a financial advisor, such advisor’s opinion as to whether the transaction is fair and reasonable to us and to our unitholders.

### Non-GAAP Financial Measures

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), adjusted EBITDA after giving effect to the exit of the butane optimization business, 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.* 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.

The following tables reconcile the non-GAAP financial measurements used by management to our most directly comparable GAAP measures for the three and six months ended June 30, 2024 and 2023, which represents EBITDA, adjusted EBITDA, adjusted EBITDA after giving effect to the exit of the butane optimization business, distributable cash flow, and adjusted free cash flow:

This allocation is based on the percentage of time spent by Martin Resource Management Corporation personnel that provide such centralized services. GAAP also permits other methods for allocation of these expenses, such as basing the allocation on the percentage of revenues contributed by a segment. The allocation of these expenses between Martin Resource Management Corporation and us is subject to a number of judgments and estimates, regardless of the method used. We can provide no assurances that our method of allocation, in the past or in the future, is or will be the most accurate or appropriate method of allocation for these expenses. Other methods could result in a higher allocation of selling, general and administrative expenses to us, which would reduce our net income.

Under the Omnibus Agreement, we are required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses. The Conflicts Committee of our general partner approved the following reimbursement amounts during the three and six months ended June 30, 2024 and 2023:

### Liquidity and Capital Resources

### General

Our primary sources of liquidity to meet operating expenses, service our indebtedness, fund capital expenditures and pay distributions to our unitholders have historically been cash flows generated by our operations, borrowings under our credit facility and access to debt and equity capital markets, both public and private. Set forth below is a description of our cash flows for the periods indicated.

### Cash Flows - Six Months Ended June 30, 2024 Compared to Six Months Ended June 30, 2023

The following table details the cash flow changes between the six months ended June 30, 2024 and 2023:

*(In thousands)*

| Net cash provided by (used in): | Six Months Ended June 30, 2024 | 2023 | Variance | Percent Change |
| --- | ---: | ---: | ---: | ---: |
| Operating activities | $21,937 | $98,774 | $(76,837) | (78)% |
| Investing activities | (37,099) | (13,410) | (23,689) | (177)% |
| Financing activities | 15,163 | (85,352) | 100,515 | 118% |
| Net increase (decrease) in cash and cash equivalents | $1 | $12 | $(11) | (92)% |

*Net cash provided by operating activities.* The decrease in net cash provided by operating activities for the six months ended June 30, 2024, includes an increase in operating results and other non-cash charges of $2.4 million, offset by an unfavorable variance in cash flows associated with changes in working capital of $79.3 million.

*Net cash used in investing activities.* Net cash used in investing activities for the six months ended June 30, 2024, increased $23.7 million. An increase in cash used of $13.2 million resulted from higher payments for capital expenditures and plant turnaround costs in 2024. Further, investments in unconsolidated entities increased $6.9 million, while net proceeds from the sale of property, plant and equipment decreased $3.5 million.

*Net cash (used in) provided by financing activities.* Net cash (used in) provided by financing activities for the six months ended June 30, 2024, increased primarily as a result of an increase in borrowings of long-term debt of $319.9 million, offset by a decrease in repayments of long-term debt of $406.2 million. Additionally, payments of debt issuance costs decreased $14.2 million.

### Total Contractual Obligations

A summary of our total contractual cash obligations as of June 30, 2024, is as follows:

| Type of Obligation | Payments due by period Total Obligation | Less than One Year | 1-3 Years | 3-5 Years | Due Thereafter |
| --- | ---: | ---: | ---: | ---: | ---: |
| Credit facility | $58,000 | $— | $58,000 | $— | $— |
| 11.5% senior secured notes, due 2028 | 400,000 | — | — | 400,000 | — |

| Finance lease obligations | 76 | 14 | 30 | 32 | — |
| Interest payable on finance lease obligations | 13 | 5 | 6 | 2 | — |
| Interest payable on fixed long-term debt obligations | 165,926 | 46,000 | 92,000 | 27,926 | — |
| Total contractual cash obligations | $698,046 | $66,814 | $184,643 | $441,844 | $4,745 |

The interest payable under our credit facility is not reflected in the above table because such amounts depend on the outstanding balances and interest rates, which vary from time to time.

*Letters of Credit.* At June 30, 2024, we had outstanding irrevocable letters of credit in the amount of $9.2 million, which were issued under our credit facility.

*Off-Balance Sheet Arrangements.* We do not have any off-balance sheet financing arrangements.

### Description of Our Indebtedness

### Credit Facility

At June 30, 2024, we maintained a $150.0 million credit facility that matures on February 8, 2027. As of June 30, 2024, we had $58.0 million outstanding under the credit facility and $9.2 million of outstanding irrevocable letters of credit, leaving a maximum available amount to be borrowed under our credit facility for future revolving credit borrowings and letters of credit of $82.9 million. After giving effect to our then current borrowings, letters of credit, and the financial covenants contained in our credit facility, we had the ability to borrow approximately $82.9 million in additional amounts thereunder as of June 30, 2024.

The credit facility is used for ongoing working capital needs and general partnership purposes, and to finance permitted investments, acquisitions and capital expenditures. The level of outstanding draws on our credit facility from January 1, 2024 through June 30, 2024 ranged from a low of $40.5 million to a high of $80.0 million.

The applicable margin for Adjusted Term SOFR borrowings at June 30, 2024 is 3.25%. The applicable margin for Adjusted Term SOFR borrowings effective July 17, 2024 remains at 3.25%.

For a description of our credit facility, see “Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Description of Our Long-Term Debt" in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 21, 2024.

### 2028 Notes

For a description of our 2028 Notes, see "Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Description of Our Long-Term Debt" in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 21, 2024.

### Capital Resources and Liquidity

Historically, we have generally satisfied our working capital requirements and funded our debt service obligations and capital expenditures with cash generated from operations and borrowings under our credit facility.

On June 30, 2024, we had cash and cash equivalents of $0.05 million and available borrowing capacity of $82.9 million under our credit facility with $58.0 million of borrowings outstanding. After giving effect to our then current borrowings, letters of credit, and the financial covenants contained in our credit facility, we had the ability to borrow approximately $82.9 million in additional amounts thereunder as of June 30, 2024.

We expect that our primary sources of liquidity to meet operating expenses, service our indebtedness, pay distributions to our unitholders and fund capital expenditures will be provided by cash flows generated by our operations, borrowings under our credit facility and access to the debt and equity capital markets. Our ability to generate cash from operations will depend upon our future operating performance, which is subject to certain risks. For a discussion of such risks, please read "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2023, filed with the SEC on February 21, 2024. In addition, due to the covenants in our credit facility, our financial and operating performance impacts the amount we are permitted to borrow under that facility.

We are in compliance with all debt covenants as of June 30, 2024, and expect to be in compliance for the next twelve months.

### Interest Rate Risk

We are subject to interest rate risk on our credit facility due to the variable interest rate and may enter into interest rate swaps to reduce this variable rate risk.

### Seasonality

A substantial portion of our revenues is dependent on sales prices of products, particularly NGLs and fertilizers, which fluctuate in part based on winter and spring weather conditions. The demand for NGLs is strongest during the winter heating season. The demand for fertilizers is strongest during the early spring planting season. However, our Terminalling and Storage and Transportation business segments and the molten sulfur business are typically not impacted by seasonal fluctuations and a significant portion of our net income is derived from our Terminalling and Storage, Sulfur Services and Transportation business segments. Further, extraordinary weather events, such as hurricanes, have in the past, and could in the future, impact our Terminalling and Storage, Sulfur Services, and Transportation business segments.

### Impact of Inflation

Inflation did not have a material impact on our results of operations for the six months ended June 30, 2024 or 2023. Inflation may increase the cost to acquire or replace property, plant and equipment. It may also increase the costs of labor and supplies. In the future, increasing energy prices for products consumed by our operations, such as diesel fuel, natural gas, chemicals, and other supplies, could adversely affect our results of operations. An increase in price of these products would increase our operating expenses which could adversely affect net income. We cannot provide assurance that we will be able to pass along increased operating expenses to our customers.

### Environmental Matters

Our operations are subject to environmental laws and regulations adopted by various governmental authorities in the jurisdictions in which these operations are conducted.

On June 15, 2024, the Partnership had a spill of less than 2,500 barrels of crude oil originating from the Partnership’s transfer pipeline, which connects our Sandyland Terminal to our refinery located in Smackover, Union County, Arkansas. The Partnership is working closely with the U.S Environmental Protection Agency (“EPA”), Arkansas Department of Energy and Environment (“ADEE”), and Arkansas Game and Fish Commission to respond to the spill. The Partnership has dedicated the necessary resources, equipment, and personnel to conduct and expedite oil recovery and cleanup activities. As of July 15, 2024, the Partnership’s response efforts have moved from emergency response status with the EPA to remediation status, which is to be overseen by the ADEE. A claim related to the crude oil spill has been made with and accepted by, subject to a reservation of rights, the Partnership’s insurance carriers. The Partnership’s deductibles under the applicable insurance policies total $1.5 million and such deductible expense has been recorded by the Partnership in the Consolidated and Condensed Statements of Operations for the three and six months ended June 30, 2024.

We incurred no material environmental costs, liabilities or expenditures to mitigate or eliminate environmental contamination during the six months ended June 30, 2023.

## Market risk

As filed, 2,094 characters.

The Partnership is exposed to commodity risk and interest rate risk in its normal business activities. The following disclosures about market risk provide an update to, and should be read in conjunction with, “Item 7A. Quantitative and Qualitative Disclosures about Market Risk” set forth in our Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on February 21, 2024.

***Commodity Risk.*** The Partnership from time to time uses derivatives to manage the risk of commodity price fluctuation. Commodity risk is the adverse effect on the value of a liability or future purchase that results from a change in commodity price. We have established a hedging policy and monitor and manage the commodity market risk associated with potential commodity risk exposure. In addition, we focus on utilizing counterparties for these transactions whose financial condition is appropriate for the credit risk involved in each specific transaction. We had no outstanding hedging positions as of June 30, 2024.

***Interest Rate Risk.*** We are exposed to changes in interest rates as a result of our credit facility, which had a weighted-average interest rate of 8.72% as of June 30, 2024. Based on the amount of unhedged floating rate debt owed by us on June 30, 2024, the impact of a 100 basis point increase in interest rates on this amount of debt would result in an increase in interest expense and a corresponding decrease in net income of approximately $0.6 million annually.

We are not exposed to changes in interest rates with respect to our 2028 Notes as these obligations are at a fixed rate. Based on the quoted prices for identical liabilities in markets that are not active at June 30, 2024, the estimated fair value of the 2028 Notes was $432.8 million. Market risk is estimated as the potential decrease in fair value of our long-term debt resulting from a hypothetical increase of a 100 basis point increase in interest rates. Such an increase in interest rates at June 30, 2024, would result in a $10.9 million decrease in the fair value of our 2028 Notes.

## Controls and procedures

As filed, 1,215 characters.

*Evaluation of disclosure controls and procedures.* In accordance with Rules 13a-15 and 15d-15 of the Exchange Act, we, under the supervision and with the participation of the Chief Executive Officer and Chief Financial Officer of our general partner, carried out an evaluation of the effectiveness of our disclosure controls and procedures (as defined in Rule 13a-15(e) and 15d-15(e) of the Exchange Act) as of the end of the period covered by this report. Based on that evaluation, the Chief Executive Officer and Chief Financial Officer of our general partner concluded that our disclosure controls and procedures were effective, as of the end of the period covered by this report, to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.

There were no changes in our internal controls over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) that occurred during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting.
