MARTIN MIDSTREAM PARTNERS L.P. 10-Q

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations 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, storage and packaging services for petroleum products and by-products including the refining of naphthenic crude oil; • 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 • NGL marketing, distribution, and transportation services. 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, 2022, Martin Resource Management Corporation owned 15.7% of our total outstanding common limited partner units. Furthermore, on December 28, 2021, Martin Resource Management Corporation indirectly acquired, through its wholly owned subsidiary, Martin Resource LLC, the remaining 49% voting interest (50% economic interest) in MMGP Holdings, LLC ("Holdings"), which is the sole member of Martin Midstream GP LLC ("MMGP"), our general partner. Such interests were previously held by certain affiliated investment funds managed by Alinda Capital Partners, which sold the interests to Senterfitt Holdings Inc. (“Senterfitt”) on November 23, 2021. At such time, Senterfitt granted Martin Resource LLC the right to purchase such interests for a period of ten years, which right was exercised on December 28, 2021. As a result, Martin Resource Management Corporation indirectly owns 100% of MMGP. Martin Resource Management Corporation directs our business operations through its ownership of our general partner. MMGP owns a 2.0% general partner interest in us, and, until November 23, 2021, MMGP owned all of our incentive distribution rights. On November 23, 2021, MMGP contributed to us all of our incentive distribution rights for no consideration, whereupon the incentive distribution rights were cancelled and cease to exist. 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. 34 Significant Recent Developments Subsequent Events Quarterly Distribution. On July 20, 2022, we declared a quarterly cash distribution of $0.005 per common unit for the second quarter of 2022, or $0.020 per common unit on an annualized basis, which will be paid on August 12, 2022 to unitholders of record as of August 5, 2022. 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, 2021, filed with the SEC on March 1, 2022.

We benefit from our relationship with Martin Resource Management Corporation through access to a significant pool of management expertise and established relationships throughout the energy industry. We do not have employees. Martin Resource Management Corporation employees are responsible for conducting our business and operating our assets on our behalf. Related Party Agreements The Omnibus Agreement requires us to reimburse Martin Resource Management Corporation for all direct expenses it incurs or payments it makes on our behalf or in connection with the operation of our business. We reimbursed Martin Resource Management Corporation for $40.2 million of direct costs and expenses for the three months ended June 30, 2022 compared to $32.6 million for the three months ended June 30, 2021.

Certain Relationships and Related Transactions, and Director Independence" set forth in our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 1, 2022. Approval and Review of Related Party Transactions 36 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. 37 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), 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 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 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 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. 38 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.

We evaluate segment performance on the basis of operating income, which is derived by subtracting cost of products sold, operating expenses, selling, general and administrative expenses, and depreciation and amortization expense from revenues. The following table sets forth our operating revenues and operating income by segment for the three and six months ended June 30, 2022 and 2021. The results of operations for these interim periods are not necessarily indicative of the results of operations which might be expected for the entire year. Our consolidated and condensed results of operations are presented on a comparative basis below. There are certain items of income and expense which we do not allocate on a segment basis. These items, including interest expense and indirect selling, general and administrative expenses, are discussed following the comparative discussion of our results within each segment.

Indirect selling, general and administrative expenses increased for the six months ended June 30, 2022 compared to the six months ended June 30, 2021 primarily due to an increase in employee-related expenses of $1.2 million, offset by a $0.4 million decrease in the indirect expenses allocated from Martin Resource Management Corporation. Martin Resource Management Corporation allocates to us a portion of its indirect selling, general and administrative expenses for services such as accounting, legal, treasury, clerical, billing, information technology, administration of insurance, engineering, general office expense and employee benefit plans and other general corporate overhead functions we share with Martin Resource Management Corporation retained businesses. 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 expense to us, which would reduce our net income. 50 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 will review and approve future adjustments in the reimbursement amount for indirect expenses, if any, annually. 51 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, 2022 Compared to Six Months Ended June 30, 2021 The following table details the cash flow changes between the six months ended June 30, 2022 and 2021: Six Months Ended June 30, Variance Percent Change 2022 2021 (In thousands) Net cash provided by (used in): Operating activities $ 28,451 $ 6,085 $ 22,366 368 % Investing activities (15,545) (9,761) (5,784) (59) % Financing activities (12,915) (601) (12,314) (2,049) % Net increase (decrease) in cash and cash equivalents $ (9) $ (4,277) $ 4,268 100 % Net cash provided by operating activities. The increase in net cash provided by operating activities for the six months ended June 30, 2022 includes an increase in operating results of $22.2 million and a favorable variance in working capital of $0.3 million. Offsetting this increase was a combined $0.1 million decrease in other non-cash charges and other non-current assets and liabilities. Net cash used in investing activities. Net cash used in investing activities for the six months ended June 30, 2022 increased $5.8 million. A rise in cash used of $6.3 million resulted from higher payments for capital expenditures and plant turnaround costs in 2022. Offsetting, net proceeds from the sale of property, plant and equipment increased $0.6 million. Net cash used in financing activities. Net cash used in financing activities for the six months ended June 30, 2022 increased primarily as a result of a $13.8 million increase in net payments of long-term borrowings and a $1.3 million increase in cash used related to additional additional consideration paid to Martin Resource Management related to its acquisition of MTI. Offsetting, payments of finance lease obligations decreased $2.5 million. Total Contractual Obligations A summary of our total contractual cash obligations as of June 30, 2022, is as follows: Payments due by period Type of Obligation Total Obligation Less than One Year 1-3 Years 3-5 Years Due Thereafter Credit facility $ 149,000 $ — $ 149,000 $ — $ — 11.5% senior secured notes, due 2025 291,381 — 291,381 — — 10.0% senior secured notes, due 2024 53,750 — 53,750 — — Throughput commitment 1,041 1,041 — — — Operating leases 35,620 9,463 11,485 6,718 7,954 Finance lease obligations 169 169 — — — Interest payable on finance lease obligations 3 3 — — — Interest payable on fixed long-term debt obligations 98,315 38,884 59,431 — — Total contractual cash obligations $ 629,279 $ 49,560 $ 565,047 $ 6,718 $ 7,954 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. 52 Letters of Credit . At June 30, 2022, we had outstanding irrevocable letters of credit in the amount of $39.0 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, 2022, we maintained a $275.0 million credit facility that matures on August 31, 2023. As of June 30, 2022, we had $149.0 million outstanding under the credit facility and $39.0 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 $87.0 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 $87.0 million in additional amounts thereunder as of June 30, 2022. The credit facility is used for ongoing working capital needs and general partnership purposes, and to finance permitted investments, acquisitions and capital expenditures. During the six months ended June 30, 2022, the level of outstanding draws on our credit facility has ranged from a low of $141.5 million to a high of $177.0 million. The credit facility is guaranteed by substantially all of our subsidiaries. Obligations under the credit facility are secured by first priority liens on substantially all of our assets and those of the guarantors, including, without limitation, inventory, accounts receivable, bank accounts, marine vessels, equipment, fixed assets and the interests in our subsidiaries. We may prepay all amounts outstanding under the credit facility at any time without premium or penalty (other than customary LIBOR breakage costs), subject to certain notice requirements. The credit facility requires mandatory prepayments of amounts outstanding thereunder with excess cash that exceeds $25.0 million and the net proceeds of certain asset sales, equity issuances and debt incurrences. Indebtedness under the credit facility bears interest at our option at the Eurodollar Rate (LIBOR), with a floor for LIBOR of 1%, plus an applicable margin, or the Base Rate (the highest of the Federal Funds Rate plus 0.50%, the 30-day Eurodollar Rate plus 1.0%, or the administrative agent’s prime rate) plus an applicable margin. We pay a per annum fee on all letters of credit issued under the credit facility, and we pay a commitment fee per annum on the unused revolving credit commitments under the credit facility. The letter of credit fee, the commitment fee and the applicable margins for our interest rate vary quarterly based on our total leverage ratio (as defined in the credit facility, being generally computed as the ratio of total funded debt to consolidated earnings before interest, taxes, depreciation, amortization and certain other non-cash charges) and are as follows as of June 30, 2022: Leverage Ratio Base Rate Loans Eurodollar Rate Loans Letters of Credit Less than 3.00 to 1.00 1.75 % 2.75 % 2.75 % Greater than or equal to 3.00 to 1.00 and less than 3.50 to 1.00 2.00 % 3.00 % 3.00 % Greater than or equal to 3.50 to 1.00 and less than 4.00 to 1.00 2.25 % 3.25 % 3.25 % Greater than or equal to 4.00 to 1.00 and less than 4.50 to 1.00 2.50 % 3.50 % 3.50 % Greater than or equal to 4.50 to 1.00 and less than 5.00 to 1.00 2.75 % 3.75 % 3.75 % Greater than or equal to 5.00 to 1.00 3.00 % 4.00 % 4.00 % The applicable margin for LIBOR borrowings at June 30, 2022 is 3.25%, with a 1% floor for LIBOR. The applicable margin for LIBOR borrowings effective July 20, 2022 is 3.00%. The credit facility includes financial covenants that are tested on a quarterly basis, based on the rolling four quarter period that ends on the last day of each fiscal quarter. In addition, the credit facility contains various covenants, which, among other things, limit our and our subsidiaries’ ability to: (i) grant or assume liens; (ii) make investments (including investments in our joint ventures) and acquisitions; (iii) enter into certain types of hedging agreements; (iv) incur or assume indebtedness; (v) sell, transfer, assign or convey assets; (vi) repurchase our equity, make distributions (including a limit on our ability to make quarterly distributions to unitholders in excess of $0.005 per unit unless our total leverage ratio is below 3.75:1:00) and certain other restricted payments; (vii) change 53 the nature of our business; (viii) engage in transactions with affiliates; (ix) enter into certain burdensome agreements; (x) make certain amendments to the Omnibus Agreement and our material agreements; and (xi) permit our joint ventures to incur indebtedness or grant certain liens. The credit facility contains customary events of default, including, without limitation: (i) failure to pay any principal, interest, fees, expenses or other amounts when due; (ii) failure to meet the quarterly financial covenants; (iii) failure to observe any other agreement, obligation, or covenant in the credit facility or any related loan document, subject to cure periods for certain failures; (iv) the failure of any representation or warranty to be materially true and correct when made; (v) our, or any of our subsidiaries’ default under other indebtedness that exceeds a threshold amount; (vi) bankruptcy or other insolvency events involving us or any of our subsidiaries; (vii) judgments against us or any of our subsidiaries, in excess of a threshold amount; (viii) certain ERISA events involving us or any of our subsidiaries, in excess of a threshold amount; (ix) a change in control (as defined in the credit facility); and (x) the invalidity of any of the loan documents or the failure of any of the collateral documents to create a lien on the collateral. The credit facility also contains certain default provisions relating to Martin Resource Management Corporation. If Martin Resource Management Corporation no longer controls our general partner, the lenders under the credit facility may declare all amounts outstanding thereunder immediately due and payable. In addition, an event of default by Martin Resource Management Corporation under its credit facility could independently result in an event of default under our credit facility if it is deemed to have a material adverse effect on us. If an event of default relating to bankruptcy or other insolvency events occurs with respect to us or any of our subsidiaries, all indebtedness under our credit facility will immediately become due and payable. If any other event of default exists under our credit facility, the lenders may terminate their commitments to lend us money, accelerate the maturity of the indebtedness outstanding under the credit facility and exercise other rights and remedies. In addition, if any event of default exists under our credit facility, the lenders may commence foreclosure or other actions against the collateral. Senior Secured Notes due 2025 and 2024 For a description of our 11.50% senior secured second lien notes due 2025 and 10.00% senior secured 1.5 lien notes due 2024, 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, 2021, filed with the SEC on March 1, 2022. 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, 2022, we had cash and cash equivalents of $0.0 million and available borrowing capacity of $87.0 million under our credit facility with $149.0 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 $87.0 million in additional amounts thereunder as of June 30, 2022. Our credit facility matures on August 31, 2023. 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, 2021, filed with the SEC on March 1, 2022. 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, 2022 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. 54 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 and refinery blending 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, 2022 or 2021. 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 could adversely affect our results of operations. Diesel fuel, natural gas, chemicals and other supplies are recorded in operating expenses. 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. We incurred no material environmental costs, liabilities or expenditures to mitigate or eliminate environmental contamination during the six months ended June 30, 2022 or 2021. 55
