Forward-Looking Statements

This Quarterly Report on Form 10-Q includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Statements included in this quarterly report that are not historical facts (including any statements concerning plans and objectives of management for future operations or economic performance, or assumptions or forecasts related thereto), including, without limitation, the information set forth in Management’s Discussion and Analysis of Financial Condition and Results of Operations, are forward-looking statements. These statements can be identified by the use of forward-looking terminology including "forecast," "may," "believe," "will," "expect," "anticipate," "estimate," "continue," or other similar words. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other "forward-looking" information. We and our representatives may from time to time make other oral or written statements that are also forward-looking statements.

These forward-looking statements are made based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements.

Because these forward-looking statements involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons, including those discussed under "Item 1A. Risk Factors" of our Annual Report on Form 10-K for the year ended December 31, ~~2023~~2024, filed with the Securities and Exchange Commission (the "SEC") on February 2124, ~~2024~~2025, and as may be updated and supplemented from time to time in our future Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.

Its four primary business lines include: terminalling, processing, and storage 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 marketing, distribution, and transportation services for natural gas liquids ("NGL") and blending and packaging services for specialty lubricants and grease.

The Partnership’s unaudited consolidated and condensed financial statements have been prepared in accordance with the requirements of Form 10-Q and U.S. Generally Accepted Accounting Principles ("U.S. GAAP") for interim financial reporting. Accordingly, these financial statements have been condensed and do not include all of the information and footnotes required by U.S. GAAP for annual audited financial statements of the type contained in the Partnership’s annual reports on Form 10-K. In the opinion of the management of Martin Midstream GP LLC ("MMGP" or the “general partner"), the Partnership’s general partner, all adjustments and elimination of significant intercompany balances necessary for a fair presentation of the Partnership’s financial position, results of operations, and cash flows for the periods shown have been made. All such adjustments are of a normal recurring nature. Results for such interim periods are not necessarily indicative of the results of operations for the full year. These financial statements should be read in conjunction with the Partnership’s audited consolidated financial statements and notes thereto included in the Partnership’s annual report on Form 10-K for the year ended December 31, ~~2023~~2024, filed with the SEC on February 2124, ~~2024~~2025.

Management has made a number of estimates and assumptions relating to the reporting of assets and liabilities and the disclosure of contingent assets and liabilities to prepare these consolidated and condensed financial statements in conformity with U.S. GAAP. Actual results could differ from those estimates.

NOTE 2. NEW ACCOUNTING PRONOUNCEMENTS

In November 2023, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures ("ASU 2023-07"). ASU 2023-07 requires annual and interim disclosures that are expected to improve reportable segment disclosures, primarily through enhanced disclosures about significant segment expenses. The provisions of ASU 2023-07 are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Partnership ~~will~~adopted ~~adopt~~ ASU 2023-07 and its expanded segment disclosure requirements in compliance with the required adoption guidelines.

~~NOTE~~In 3December 2023, the FASB issued Accounting Standards Update No. 2023-09, “Improvements to Income Tax Disclosures” ("ASU 2023-09"), which requires disaggregated information about a reporting entity’s effective tax rate reconciliation as well as additional information on income taxes paid. The provisions of ASU 2023-09 are effective for annual reporting periods beginning after December 15, 2024, with early adoption permitted and can be applied on either a prospective or retroactive basis. Once adopted, ~~EXIT~~the OFPartnership ~~BUTANE~~will ~~OPTIMIZATION~~include ~~BUSINESS~~the additional disclosure required by ASU 2023-09 in it's consolidated financial statements.

During the second quarter of 2023, the Partnership completed its previously announced exit from its butane optimization business at the conclusion of the butane selling season. This exit did not qualify as discontinued operations in accordance with FASB Accounting Standards Codification ("ASC") Topic 205. Going forward, with respect to butane, the Partnership will operate as a fee-based butane logistics business, primarily continuing to utilize its north Louisiana underground storage assets, which have both truck and rail capability. This logistics business will also utilize the Partnership's truck transportation assets for fee-based product movements. As a result of this new business model, the Partnership will no longer carry butane inventory, enabling the Partnership to reduce commodity risk exposure, cash flow and earnings volatility, and working capital requirements. The following revenues and costs, which are included in the financial results for all periods presented, are not expected to be incurred under the new fee-based butane logistics business model. The butane optimization business has historically been included in the Partnership's Specialty Products operating segment.

Revenue is measured based on a consideration specified in a contract with a customer and excludes amounts collected on behalf of third parties where the Partnership is acting as an agent. The Partnership recognizes revenue when the Partnership satisfies a performance obligation, which typically occurs when the Partnership transfers control over a product to a customer or as the Partnership delivers a service.

The following is a description of the principal activities - separated by reportable segments - from which the Partnership generates revenue.

Terminalling and Storage Segment

Revenue is recognized for storage contracts based on the contracted monthly tank fixed fee. For throughput contracts, revenue is recognized based on the volume moved through the Partnership’s terminals at the contracted rate. For storage and throughput contracts at the Partnership's underground NGL storage facility, revenue is recognized based on the volume stored and moved through the facility at the contracted rate. For the Partnership’s tolling agreement, revenue is recognized based on the contracted monthly reservation fee and throughput volumes moved through the facility. Throughput and storage revenue in the table above includes non-cancelable revenue arrangements that are under the scope of ASC 842, whereby the Partnership has committed certain Terminalling and Storage assets in exchange for a minimum fee.

Transportation Segment

Revenue related to land transportation is recognized for line hauls based on a mileage rate. For contracted trips, revenue is recognized upon completion of the particular trip. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

and moved through the facility at the contracted rate. For the Partnership’s tolling agreement, revenue is recognized based on the contracted monthly reservation fee and throughput volumes moved through the facility. Throughput and storage revenue in the table above includes non-cancelable revenue arrangements that are under the scope of ASC 842, whereby the Partnership has committed certain Terminalling and Storage assets in exchange for a minimum fee.

Transportation Segment

Revenue related to marine transportation is recognized for time charters based on a per day rate. For contracted trips, revenue is recognized upon completion of the particular trip. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

Sulfur Services Segment

Revenue from sulfur and fertilizer product sales is recognized when the customer takes title to the product. Delivery of product is invoiced as the transaction occurs and is generally paid within a month. Revenue from sulfur services is recognized as services are performed during each monthly period. The performance of the service is invoiced as the transaction occurs and is generally paid within a month.

Specialty Products Segment

~~Natural Gas Liquids ("~~NGL") revenue is recognized when title is transferred, which is generally when the product is delivered by truck, rail, or pipeline to the Partnership's NGL customers or when the customer picks up the product from our facilities. When lubricants are sold by truck or rail, revenue is recognized when title is transferred, which is generally when the product leaves the Partnership's facility, but can vary based on the specific terms of the contract. Delivery of product is invoiced as the transaction occurs and is generally paid within a month.

The table below includes estimated minimum revenue expected to be recognized in the future related to performance obligations that are unsatisfied at the end of the reporting period. The Partnership applies the practical expedient in ASC 606-10-50-14(a) and does not disclose information about remaining performance obligations that have original expected durations of one year or less.

In addition, the Partnership has non-cancelable revenue arrangements that are under the scope of ASC 842 whereby we have committed certain terminalling and storage assets in exchange for a minimum fee. Future minimum revenues the Partnership expects to receive under these non-cancelable arrangements as of March 31, 2025, are as follows: 2025 - $16,538; 2026 - $13,582; 2027 - $12,620; 2028 - $12,165; 2029 - $9,860; subsequent years - $8,538.

NOTE 98. PARTNERS' CAPITAL (DEFICIT)

As of ~~September~~March 3031, ~~2024~~2025, Partners’ capital (deficit) consisted of 39,~~001~~055,086 common limited partner units, representing a 98% partnership interest, and a 2% general partner interest. Martin Resource Management Corporation, through subsidiaries, owned 6,~~114~~372,~~532~~252 of the Partnership's common limited partner units representing approximately 1516.73% of the Partnership's outstanding common limited partner units. ~~Martin Midstream GP LLC ("~~MMGP"), the Partnership's general partner, owns the 2% general partnership interest.

The partnership agreement of the Partnership (the "Partnership Agreement") contains specific provisions for the allocation of net income and losses to each of the partners for purposes of maintaining their respective partner capital accounts.

Impact on Partners' Capital (Deficit) Related to Transactions Between Entities Under Common Control

Under ASC 805, assets and liabilities transferred between entities under common control are accounted for at the historical cost of those entities' ultimate parent, in a manner similar to a pooling of interests. Any difference in the amount paid by the transferee versus the historical cost of the assets transferred is recorded as an adjustment to equity (contribution or distribution) by the transferee. This is in contrast with a business combination between unrelated parties, where assets and liabilities are recorded at their fair values at the acquisition date, with any excess of amounts paid over the fair value representing goodwill. From time to time, the most recent being in 2019, the Partnership has entered into common control acquisitions from Martin Resource Management Corporation. The consideration transferred totaling $552,058 exceeds the historical cost of the net assets received. This excess of the purchase price over the historical cost of the net assets received has resulted in cumulative deemed distributions of $289,019 reflected as reductions to Partners' capital.

Distributions of Available Cash

The Partnership distributes all of its available cash (as defined in the Partnership Agreement) within 45 days after the end of each quarter to unitholders of record and to the general partner. Available cash is generally defined as all cash and cash equivalents of the Partnership on hand at the end of each quarter less the amount of cash reserves its general partner determines in its reasonable discretion is necessary or appropriate to: (i) provide for the proper conduct of the Partnership’s business; (ii) comply with applicable law, any debt instruments or other agreements; or (iii) provide funds for distributions to unitholders and the general partner for any one or more of the next four quarters, plus all cash on the date of determination of available cash for the quarter resulting from working capital borrowings made after the end of the quarter.

Net Income per Unit

The Partnership follows the provisions of the FASB ASC 260-10 related to earnings per share, which addresses the application of the two-class method in determining income per unit for master limited partnerships having multiple classes of securities that may participate in partnership distributions accounted for as equity distributions. Undistributed earnings are allocated to the general partner and limited partners utilizing the contractual terms of the Partnership Agreement. When current period distributions are in excess of earnings, the excess distributions for the period are to be allocated to the general partner and limited partners based on their respective sharing of income and losses specified in the Partnership Agreement. Additionally, as required under FASB ASC 260-10-45-61A, unvested share-based payments that entitle employees to receive non-forfeitable distributions are considered participating securities, as defined in FASB ASC 260-10-20, for earnings per unit calculations.

For purposes of computing diluted net income per unit, the Partnership uses the more dilutive of the two-class and if-converted methods. Under the if-converted method, the weighted-average number of subordinated units outstanding for the period is added to the weighted-average number of common units outstanding for purposes of computing basic net income per unit and the resulting amount is compared to the diluted net income per unit computed using the two-class method. The following is a reconciliation of net income allocated to the general partner and limited partners for purposes of calculating net income attributable to limited partners per unit:

Long-Term Incentive Plans

The Partnership's general partner has long-term incentive plans for employees and directors of the general partner and its affiliates who perform services for the Partnership.

2021 Phantom Unit Plan

On July 21, 2021, the board of directors of the general partner of the Partnership (the "Board") and the compensation committee of the ~~general~~Board ~~partner's board of directors~~ (the "Compensation Committee") approved the Martin Midstream Partners L.P. 2021 Phantom Unit Plan (the “Plan”), effective as of the same date. The Plan permits the awards of phantom units and phantom unit appreciation rights (collectively, "phantom unit awards") to any employee or non-employee director of the Partnership, including its executive officers. The awards may be time-based or performance-based and will be paid, if at all, in cash.

The award of a phantom unit entitles the participant to a cash payment equal to the value of the phantom unit on the vesting date or dates, which value is the fair market value of a common unit of the Partnership (a “Unit”) on such vesting date or dates. The award of a phantom unit appreciation right entitles the recipient to a cash payment equal to the difference between the value of a phantom unit on the vesting date or dates in excess of the value assigned by the Compensation Committee to the phantom unit as of the grant date. Phantom units and phantom unit appreciation rights granted to participants do not confer upon participants any right to a Unit.

On July 21, 2021, the Compensation Committee approved forms of time-based award agreements for phantom units and phantom unit appreciation rights, both of which awards vest in full on the third anniversary of the grant date. The grant date value of a phantom unit under a phantom unit appreciation right award is equal to the average of the closing price for a Unit during the 20 trading days immediately preceding the grant date of the award.

Generally, vesting of an award is subject to a participant remaining continuously employed with the Partnership through the vesting date. However, if prior to the vesting date (i) a participant is terminated without cause (as defined in the award agreement) or terminates employment after the participant has attained both the age of 65 and ten years of employment (“retirement-eligible”), a prorated portion of the award will vest and be paid in cash no later than the 30th day following such termination date (subject to a six-month delay in payment for certain retirement-eligible participants) or (ii) there is a change in control of the Partnership (as defined in the Plan), the award will vest in full and be paid in cash no later than the 30th day following the date of the change of control; provided, that the participant has been in continuous employment through the termination or change in control date, as applicable.

On ~~July 21, 2021, 620,000 phantom units and 1,245,000 phantom unit appreciation rights were granted to employees of the general partner and its affiliates who perform services for the Partnership. On~~ April 20, 2022, the ~~board~~Board ~~of directors of the general partner of the Partnership~~ and the Compensation Committee approved the First Amendment to the Plan, effective as of the same date, which amendment increased the total number of phantom units available for grant under the Plan from 2,000,000 units to 5,000,000 units. On April 20, 2022, 365,000 phantom units and 1,097,500 phantom unit appreciation rights were granted to employees of the general partner and its affiliates who perform services for the Partnership. On July 19, 2023, 1,179,500 phantom units and 505,500 phantom unit appreciation rights were granted to employees of the general partner and its affiliates who perform services for the Partnership.

2025 Phantom ~~unit~~Unit awards are recorded in operating expense and selling, general and administrative expense based on the fair value of the vested portion of the awards on the balance sheet date. The fair value of these awards is updated at each balance sheet date and changes in the fair value of the vested portions of the awards are recorded as increases or decreases to compensation expense within operating expense and selling, general and administrative expense in the Consolidated and Condensed Statements of Operations.Plan All of the Partnership's outstanding phantom unit awards at September 30, 2024, met the criteria to be treated under liability classification in accordance with ASC 718, given that these awards will settle in cash on the vesting date.

Compensation expense for the phantom awards is based on the fair value of the units as of the balance sheet date as further discussed below, and such costs are recognized ratably over the service period of the awards. As the fair value of liability awards is required to be re-measured each period end, stock compensation expense amounts recognized in future periods for these awards will vary. The estimated future cash payments of these awards are presented as liabilities within "Other current liabilities" and "Other long-term obligations" in the Consolidated and Condensed Balance Sheets. As of March 31, 2025, there was a total of $6,611 of unrecognized compensation costs related to non-vested phantom unit awards. These costs are expected to be recognized over a remaining life of 1.94 years.

The fair value of the phantom unit awards was estimated using a Monte Carlo valuation model as of the balance sheet date. The Monte Carlo valuation model is based on random projections of stock price paths and must be repeated numerous times to achieve a probabilistic assessment. Expected volatility was calculated based on the historical volatility of the Partnership’s common units as well as set of peer companies.

Restricted Unit Plan

On May 26, 2017, the unitholders of the Partnership approved the Martin Midstream Partners L.P. 2017 Restricted Unit Plan (the "2017 LTIP"). The 2017 LTIP currently permits the grant of awards covering an aggregate of 3,000,000 common units, all of which can be awarded in the form of restricted units. The 2017 LTIP is administered by the Compensation Committee.

A restricted unit is a unit that is granted to grantees with certain vesting restrictions, which may be time-based and/or performance-based. Once these restrictions lapse, the grantee is entitled to full ownership of the unit without restrictions. The Compensation Committee may determine to make grants under the 2017 LTIP containing such terms as the Compensation Committee shall determine under the 2017 LTIP. With respect to time-based restricted units ("TBRUs"), the Compensation Committee will determine the time period over which restricted units granted to employees and directors will vest. The Compensation Committee may also award a percentage of restricted units with vesting requirements based upon the achievement of specified pre-established performance targets ("Performance Based Restricted Units" or "PBRUs"). The performance targets may include, but are not limited to, the following: revenue and income measures, cash flow measures, net income before interest expense and income tax expense ("EBIT"), net income before interest expense, income tax expense, and depreciation and amortization ("EBITDA"), distribution coverage metrics, expense measures, liquidity measures, market measures, corporate sustainability metrics, and other measures related to acquisitions, dispositions, operational objectives and succession planning objectives. PBRUs are earned only upon our achievement of an objective performance measure for the performance period. PBRUs which vest are payable in common units. Unvested units granted under the 2017 LTIP may or may not participate in cash distributions depending on the terms of each individual award agreement.

The restricted units issued to directors generally vest in equal annual installments over a four-year period. Restricted units issued to employees generally vest in equal annual installments over three years of service. All of the Partnership's outstanding restricted unit awards at ~~September~~March 3031, ~~2024~~2025, met the criteria to be treated under equity classification.

InOn February ~~2024~~11, 2025, the Partnership issued 2818,~~760~~000 TBRUs to each of the Partnership's three independent directors under the 2017 LTIP. These restricted common units vest in equal installments of 76,~~190~~000 units on January 24, ~~2025,~~ 2026, 2027, 2028, and ~~2028~~2029.

Diesel Fuel Terminal Services Agreement. Effective October 1, 2022, the Partnership entered into a third amended and restated terminalling services agreement under which it provides terminal services to Martin Energy Services LLC (“MES”), a wholly owned subsidiary of Martin Resource Management Corporation, for fuel distribution utilizing marine shore based terminals owned by the Partnership. This agreement amended the existing arrangement between the Partnership and MES by eliminating any minimum throughput volume requirements and increasing the per gallon throughput fee. The primary term of this agreement expired on December 31, 2023, but will continue on a year to year basis until terminated by either party by giving at least 90 days’ written notice prior to the end of any term. Effective January 1, 2024, this agreement was amended to increase the throughput rate and to establish a minimum throughput volume.

Miscellaneous Terminal Services Agreements. The Partnership is currently party to several terminal services agreements and from time to time the Partnership may enter into other terminal service agreements for the purpose of providing terminal services to related parties. Individually, each of these agreements is immaterial but when considered in the aggregate they could be deemed material. These agreements are throughput based with a minimum volume commitment. Generally, the fees due under these agreements are adjusted annually based on a price index.

Other Agreements

Cross Tolling Agreement. The Partnership is a party to an amended and restated tolling agreement with Cross Oil Refining and Marketing, Inc. ("Cross") dated October 28, 2014, under which the Partnership processes crude oil into finished products, including naphthenic lubricants, distillates, asphalt and other intermediate cuts for Cross. The tolling agreement expires November 25, 2031. Under this tolling agreement, Cross agreed to process a minimum of 6,500 barrels per day of crude oil at the facility at a fixed price per barrel. Any additional barrels are processed at a modified price per barrel. In addition, Cross agreed to pay a monthly reservation fee and a periodic fuel surcharge fee based on certain parameters specified in the tolling agreement. Further, certain capital improvements, to the extent requested by Cross, are reimbursed through a capital recovery fee. All of these fees (other than the fuel surcharge) are subject to escalation annually based upon the greater of 3% or the increase in the Consumer Price Index for a specified annual period.

East Texas Mack Leases. MTI leases equipment, including tractors and trailers, from East Texas Mack Sales ("East Texas Mack"). Certain of our directors or officers are owners of East Texas Mack, including entities affiliated with Ruben Martin, who owns approximately 47% of the issued and outstanding stock of East Texas Mack. Amounts paid to East Texas Mack for tractor and trailer lease payments and lease residuals for the three months ended March 31, 2025 and 2024, were $1,690 and $938, respectively.

The Partnership's four reportable segments are comprised of (1) Terminalling and Storage, (2) Transportation, (3) Sulfur Services and (4) Specialty Products. The operating segments within each of our reportable segments have been aggregated based on the similarity of their economic and other characteristics, including different product type and services.

The Terminalling and Storage segment generates revenue by providing terminalling, processing, and storage services for petroleum products and by-products. Storage revenue is earned through contracted monthly tank fixed fees, while throughput revenue is based on the volume moved through the Partnership’s terminals at contracted rates. Tolling revenue is derived from contracted monthly reservation fees and throughput volumes processed at the facility.

The Transportation segment earns revenue by offering land and marine transportation services for petroleum products, by-products, chemicals, and specialty products. Land transportation revenue is based on mileage rates for line hauls or completion of contracted trips. Marine transportation revenue comes from time charters, calculated on a per-day basis, or from the completion of contracted trips.

The Sulfur Services segment generates revenue by providing processing, manufacturing, marketing, and distribution services for sulfur and sulfur-based products. Revenue from sulfur and fertilizer product sales is recognized when the customer takes title to the product. Revenue from sulfur services is earned as services are performed during each monthly period.

NOTE 12. COMMITMENTS AND CONTINGENCIES

Contingencies

From time to time, the Partnership is subject to various claims and legal actions arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the Partnership.

On December 31, 2015, the Partnership received a demand from a customer in its lubricants packaging business for defense and indemnity in connection with various lawsuits filed against it, which generally alleged that the customer engaged in unlawful and deceptive business practices in connection with its marketing and advertising of its private label motor oil (the “Marketing Lawsuits”). The Partnership disputed and continues to dispute that it has any obligation to defend or indemnify the customer for the customer’s conduct. Accordingly, on January 7, 2016, the Partnership filed a Complaint for Declaratory Judgment in the Chancery Court of Davidson County, Tennessee (the “Tennessee Court”), under Case No. 16-0018-BC, requesting a judicial determination that the Partnership did not owe the customer the demanded defense and indemnity obligations (the “Litigation”). The Marketing Lawsuits pending in federal court against the customer were transferred to the U.S. District Court for the Western District of Missouri under the consolidated case MDL No. 2709 for pretrial proceedings (the “Consolidated Lawsuits”). On March 1, 2017, at the joint request of the customer and the Partnership, the Tennessee Court administratively closed the Litigation. In 2021, the customer settled the Consolidated Lawsuits. On December 17, 2021, at the request of the customer, the Tennessee Court reopened the Litigation and the customer asserted various counterclaims against the Partnership seeking, among other things, to recover its costs of defending and settling the Consolidated Lawsuits. At this time, we are unable to determine what ultimate exposure we may have in this matter, if any. The Partnership intends to vigorously defend the counterclaims asserted by the customer in the Litigation. The trial for the Litigation is expected to be held in the ~~second~~first half of ~~2025~~2026.

NOTE 1413. FAIR VALUE MEASUREMENTS

The Partnership uses a valuation framework based upon inputs that market participants use in pricing certain assets and liabilities. These inputs are classified into two categories: observable inputs and unobservable inputs. Observable inputs represent market data obtained from independent sources. Unobservable inputs represent the Partnership's own market assumptions. Unobservable inputs are used only if observable inputs are unavailable or not reasonably available without undue cost and effort. The two types of inputs are further prioritized into the following hierarchy:

Level 1: Quoted market prices in active markets for identical assets or liabilities.

Level 2: Observable market-based inputs or unobservable inputs that are corroborated by market data.

Level 3: Unobservable inputs that reflect the entity's own assumptions and are not corroborated by market data.

The Partnership is required to disclose estimated fair values for its financial instruments. Fair value estimates are set forth below for these financial instruments. The following methods and assumptions were used to estimate the fair value of each class of financial instrument:

•Accounts and other receivables, trade and other accounts payable, accrued interest payable, other accrued liabilities, income taxes payable and due from/to affiliates: The carrying amounts approximate fair value due to the short maturity and highly liquid nature of these instruments, and as such these have been excluded from the table below. There is negligible credit risk associated with these instruments.

•Current and non-current portion of long-term debt: The carrying amount of the credit facility approximates fair value due to the debt having a variable interest rate and is in Level 2. The estimated fair value of the 2028 Notes is considered Level 2, as the fair value is based upon quoted prices for identical liabilities in markets that are not active.

NOTE 1514. INVESTMENT IN DSM SEMICHEM LLC

On October 19, 2022, Martin ELSA Investment LLC, the Partnership's 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 the Partnership's 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, the Partnership will be the exclusive provider of feedstock to the ELSA Facility. The Partnership, through its affiliate MTI, will also provide land transportation services for the ELSA produced by DSM. On April 1, 2024, the Partnership contributed $6,500 in cash to DSM, which represents the cash contributions required pursuant to DSM's limited liability agreement for the Partnership's 10% non-controlling interest. Also, in conjunction with the formation of DSM, we contributed approximately 22 acres of land. The Partnership recognizes its 10% interest in DSM as "Investment in DSM Semichem LLC" on its Consolidated and Condensed Balance Sheets. The Partnership accounts for its ownership interest in DSM under the equity method of accounting.

The operations of a partnership are generally not subject to income taxes, except for Texas margin tax, because its income is taxed directly to its partners. Current state income taxes attributable to the Texas margin tax relating to the operation of the Partnership of $270 and $120 were recorded in income tax expense for the three months ended September 30, 2024 and 2023, respectively. Current state income taxes attributable to the Texas margin tax relating to the operation of the Partnership of $820 and $320 were recorded in income tax expense for the nine months ended September 30, 2024 and 2023, respectively. Deferred taxes applicable to the Texas margin tax relating to the operation of the Partnership are immaterial. 29

MTI, a wholly owned subsidiary of the Partnership, is subject to income taxes due to its corporate structure (the "Taxable Subsidiary"). Total income tax expense of $796 and $668, related to the operation of the Taxable Subsidiary, for the three months ended September 30, 2024 and 2023, resulted in an effective income tax rate ("ETR") of 33.36% and 23.96%, respectively. Total income tax expense of $2,814 and $3,299, related to the operation of the Taxable Subsidiary, for the nine months ended September 30, 2024 and 2023, resulted in an ETR of 25.17% and 24.88%, respectively.

The increase in the provision for income taxes and the ETR for the income taxes during the three months ended September 30, 2024, was primarily due to an increase in permanent differences, compared to the same period in 2023. The decrease in the provision for income taxes during the nine months ended September 30, 2024, was primarily due to a favorable true-up to state net operating loss carryforwards, compared to the same period in 2023. The increase in the ETR for the income taxes during the nine months ended September 30, 2024, was primarily due to a decrease in income before income taxes in the current period, compared to the same period in 2023.

A current federal income tax expense of $471 and $179, related to the operation of the Taxable Subsidiary, was recorded for the three months ended September 30, 2024 and 2023, respectively. A current federal income tax expense of $2,047 and $666, related to the operation of the Taxable Subsidiary, was recorded for the nine months ended September 30, 2024 and 2023, respectively.

MTI, a wholly owned subsidiary of the Partnership, is subject to income taxes due to its corporate structure (the "Taxable Subsidiary"). Total income tax expense of $700 and $716, related to the operation of the Taxable Subsidiary, for the three months ended March 31, 2025 and 2024, resulted in an effective income tax rate ("ETR") of 32.86% and 15.73%, respectively.

The decrease in the provision for income taxes during the three months ended March 31, 2025, compared to the same period in 2024, was primarily due to a decrease in income before taxes in the current period. The increase in the ETR during the three months ended March 31, 2025, compared to the same period in 2024, was primarily due to a favorable true-up to state net operating loss carryforwards in the prior period.

A current federal income tax expense of $722 and $791, related to the operation of the Taxable Subsidiary, was recorded for the three months ended March 31, 2025 and 2024, respectively. A current state income tax expense of $192 and $251, related to the operation of the Taxable Subsidiary, was recorded for the three months ended March 31, 2025 and 2024, respectively.

With respect to MTI, income taxes are accounted for under the asset and liability method pursuant to the provisions of ASC 740 related to income taxes. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

A deferred tax expense (benefit) related to the MTI temporary differences of $~~131~~(214) and $~~456~~(326) was recorded for the three months ended ~~September~~March 3031, ~~2024~~2025 and ~~2023, respectively. A deferred tax expense related to the MTI temporary differences of $157 and $2,322 was recorded for the nine months ended September 30,~~ 2024 ~~and 2023~~, respectively. A net deferred tax asset of $10,~~043~~160 and $109,~~200~~946, related to the cumulative book and tax temporary differences, existed at ~~September~~March 3031, ~~2024~~2025 and December 31, ~~2023~~2024, respectively.

All income tax positions taken for all open years are more likely than not to be sustained based upon their technical merit under applicable tax laws.

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, 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~~NGLs ~~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 ~~September~~March 3031, ~~2024~~2025, Martin Resource Management Corporation owned 1516.73% 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.

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 September 30, 2024, we have funded approximately $26.4 million toward ELSA related project costs.

Subsequent Events

Quarterly Distribution. On ~~October~~April 16, ~~2024~~2025, we declared a quarterly cash distribution of $0.005 per common unit for the ~~third~~first quarter of ~~2024~~2025, or $0.020 per common unit on an annualized basis, which will be paid on ~~November~~May 1415, ~~2024~~2025, to unitholders of record as of ~~November~~May 78, ~~2024~~2025.

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~~2024, filed with the SEC on February 2124, ~~2024~~2025.

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 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), 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, and transaction costs associated with business combination, merger, and divestiture activities. 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.

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.

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 nine months ended September 30, 2024 and 2023, which represents EBITDA, adjusted EBITDA, Credit Adjusted EBITDA, distributable cash flow, and adjusted free cash flow:

Results of Operations

The results of operations for the three ~~and nine~~ months ended ~~September~~March 3031, ~~2024~~2025 and ~~2023~~2024, have been derived from our consolidated and condensed financial statements.

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 nine~~ months ended ~~September~~March 3031, ~~2024~~2025 and ~~2023~~2024. 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.

Operating expenses increased primarily as a result of liability insurance claims of $1.6 million (crude pipeline spill), insurance premiums of $1.0 million, employee-related expenses of $1.0 million, repairs and maintenance of $0.7 million at our Smackover refinery, operating supplies of $0.6 million and lease expense of $0.2 million. These increases were offset by a decrease in natural gas utilities of $3.0 million.

Selling, general and administrative expenses. Selling, general and administrative expenses increased primarily due to higher employee-related expenses.

Depreciation and amortization. The increase in depreciation and amortization is primarily the result of capital expenditures offset by recent disposals.

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 expenses to us, which would reduce our net income.

46 Under the Omnibus Agreement, we are required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses.

Description of Our Indebtedness

Credit Facility

At ~~September~~March 3031, ~~2024~~2025, we maintained a $150.0 million credit facility that matures on February 8, 2027. As of ~~September~~March 3031, ~~2024~~2025, we had $8666.50 million outstanding under the credit facility and $9.2 million of outstanding irrevocable letters of credit, leaving a maximum ~~available~~ amount available to be borrowed under our credit facility for future revolving credit borrowings and letters of credit of $5474.49 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 $5423.4 million in additional amounts thereunder as of ~~September~~March 3031, ~~2024~~2025.

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~~2025 through ~~September~~March 3031, ~~2024~~2025 ranged from a low of $4053.5 million to a high of $~~102~~86.50 million.

The applicable margin for Adjusted Term SOFR borrowings at ~~September~~March 3031, ~~2024~~2025 is 3.25%. The applicable margin for Adjusted Term SOFR borrowings effective ~~October~~April 16, ~~2024~~2025 is 3.50%.

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, 2024, filed with the SEC on February 24, 2025.

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~~2024, filed with the SEC on February 2124, ~~2024~~2025.

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 September 30, 2024, we had cash and cash equivalents of $0.06 million and available borrowing capacity of $54.4 million under our credit facility with $86.5 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 $54.4 million in additional amounts thereunder as of September 30, 2024. 45

WeOn ~~expect that our primary sources of liquidity to meet operating expenses~~March 31, ~~service our indebtedness~~2025, ~~pay~~we ~~distributions~~had tocash ~~our unitholders~~ and ~~fund~~cash ~~capital~~equivalents ~~expenditures~~of ~~will~~$0.05 bemillion ~~provided~~and byavailable ~~cash~~borrowing ~~flows~~capacity ~~generated~~of by$74.9 ~~our~~million ~~operations, borrowings~~ under our credit facility ~~and~~with ~~access to the debt and equity capital markets~~$66. ~~Our~~0 ~~ability~~million ~~to generate cash from operations will depend upon our future operating performance, which is subject to certain risks. For a discussion~~ of ~~such~~borrowings ~~risks, please read "Item 1A~~outstanding. After ~~Risk~~giving ~~Factors"~~effect ofto our ~~Form~~then ~~10-K~~current ~~for the year ended December 31~~borrowings, ~~2023,~~letters ~~filed~~of ~~with the SEC on February 21~~credit, ~~2024.

Our ability to generate cash from operations will depend upon our future operating performance, which is subject to certain risks. For a discussion of ~~September 30~~such risks, please read "Item 1A. Risk Factors" of our Form 10-K for the year ended December 31, 2024, ~~and~~filed ~~expect~~with the SEC on February 24, 2025. In addition, due to bethe covenants in ~~compliance~~our ~~for~~credit facility, our financial and operating performance impacts the ~~next~~amount ~~twelve~~we ~~months~~are permitted to borrow under that facility.

We are in compliance with all debt covenants as of March 31, 2025, 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 ~~nine~~three months ended ~~September~~March 3031, ~~2024~~2025 or ~~2023~~2024. 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~~experienced a spill of less than 2,500 barrels of crude oil ~~originating~~ from ~~the~~its ~~Partnership’s~~ transfer pipeline, ~~which~~connecting ~~connects~~the ~~our~~ Sandyland Terminal to ~~our~~the refinery ~~located~~ in Smackover, Union County, Arkansas. The Partnership ispromptly ~~working~~coordinated ~~closely~~ with the U.S Environmental Protection Agency (the “EPA”), Arkansas Department of Energy and Environment (the “ADEE”), and Arkansas Game and Fish Commission, todedicating ~~respond to~~ the ~~spill. The Partnership has dedicated the~~ necessary resources, equipment, and personnel to ~~conduct and~~ expedite oil recovery and cleanup activities. As ofIn October ~~15,~~ 2024, the EPA transitioned the Partnership’s response ~~efforts have moved~~ from emergency response status ~~with~~to remediation status under ADEE oversight. On October 11, 2024, the ~~EPA~~ADEE tonotified ~~remediation~~the ~~status~~Partnership that documentation, ~~which~~observations, isand todata beindicated ~~overseen~~the byPartnership completed all remedial actions to the ~~ADEE~~maximum practical extent. A No further remediation is required at this time. The Partnership submitted a claim related to the ~~crude oil~~ spill, ~~has~~which ~~been~~was ~~made~~accepted ~~with~~by ~~and~~its ~~accepted~~insurance bycarriers, 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~~was ~~been~~ recorded by the Partnership in the Consolidated and Condensed Statements of Operations for the three and ~~nine~~six months ended ~~September~~June 30, 2024. As of April 21, 2025, no fines or penalties have been assessed in relation to the spill.

We incurred no material environmental costs, liabilities or expenditures to mitigate or eliminate environmental contamination during the ~~nine~~three months ended ~~September 30~~March 31, ~~2023~~2025.

On March 14, 2025, President Trump signed a Joint Resolution of Disapproval under the Congressional Review Act to prohibit the Inflation Reduction Act’s waste methane emissions charge rules, which were finalized in November 2024, from taking effect.

On March 6, 2024, the SEC adopted final rules that require the registrants to disclose certain climate-related information in registration statements and annual reports. Litigation challenging the new rule was filed by multiple parties in multiple jurisdictions, which was consolidated and assigned to the U.S. Court of Appeals for the Eighth Circuit. On April 4, 2024, the SEC announced it was voluntarily delaying the implementation of the climate disclosure regulations while the U.S. Court of Appeals considered the litigation. On March 27, 2025, the SEC voted to end the defense of the rules in the litigation.


Item 3.			Quantitative and Qualitative Disclosures about Market Risk

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~~2024, filed with the SEC on February 2124, ~~2024~~2025.

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 ~~September~~March 3031, ~~2024~~2025.

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 87.4484% as of ~~September~~March 3031, ~~2024~~2025. Based on the amount of unhedged floating rate debt owed by us on ~~September~~March 3031, ~~2024~~2025, 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 $0.97 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 ~~September~~March 3031, ~~2024~~2025, the estimated fair value of the 2028 Notes was $~~441~~425.64 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 ~~September~~March 3031, ~~2024~~2025, would result in a $108.16 million decrease in the fair value of our 2028 Notes.

5148


Item 4.			Controls and Procedures

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.

PART II - OTHER INFORMATION


Item 1.			Legal Proceedings

From time to time, we are subject to certain legal proceedings, claims and disputes that arise in the ordinary course of our business. Although we cannot predict the outcomes of these legal proceedings, these actions, in the aggregate, could have a material adverse impact on our financial position, results of operations or liquidity. A description of our legal proceedings is included in "Item 1. Financial Statements, Note 1312. Commitments and Contingencies"," and is incorporated herein by reference.


Item 1A.			Risk Factors

There have been no material changes to the Partnership's risk factors since our Annual Report on Form 10-K for the year ended December 31, ~~2023~~2024, filed with the SEC on February 2124, ~~2024~~2025, except as follows.

The Merger is subject to conditions, including some conditions that may not be satisfied on a timely basis, if at all. Failure to complete the Merger, or significant delays in completing the Merger, could negatively affect our business and financial results and the trading prices of our common units.

The completion of the Merger is not assured and is subject to certain risks, including the risk that certain conditions of the Merger Agreement, such as required regulatory approvals and the approval of our unitholders, some of which are beyond the parties’ control, are not satisfied or waived, which may prevent, delay or otherwise result in the Merger not occurring. The Merger Agreement contains conditions that, if not satisfied or waived, would result in the Merger not occurring, even though our common unitholders may have voted in favor of the Merger-related proposals presented to them. Failure to complete, or significant delays in completing, the Merger with Martin Resource Management Corporation could negatively affect the price of our common units and may have a material adverse impact on our subsequent financial condition, results of operations and cash flows.

We may be subject to lawsuits regarding the Merger, which could materially adversely affect our operations and financial condition or prevent or delay completion of the Merger.

Our directors and officers may be subject to lawsuits relating to the Merger. While we will evaluate and defend against any actions vigorously, the costs of the defense of such lawsuits and other effects of such litigation could have an adverse effect on our operations and financial condition. Failure to complete, or significant delays in completing, the Merger could negatively affect the price of our common units and may have a material adverse impact on our subsequent financial condition, results of operations and cash flows.

We will be subject to business uncertainties while the Merger is pending, which could adversely affect our business.

Uncertainty about the effect of the Merger on the Partnership, its subsidiaries and the companies that do business with us may have an adverse effect on us. These uncertainties may impair our ability to attract, retain and motivate key personnel and suppliers until the Merger is completed and for a period of time thereafter, and could cause those that transact with us to seek to change their existing business relationships with us.

We may incur substantial transaction-related costs in connection with the Merger.

We and Martin Resource Management Corporation expect to incur nonrecurring transaction-related costs associated with completing the Merger. Nonrecurring transaction costs include, but are not limited to, fees paid to legal, financial and accounting advisors, filing fees, proxy solicitation costs and printing costs.

If the Merger Agreement is terminated, we may, under specified circumstances, be responsible for a termination fee of $2.5 million or the reimbursement of Martin Resource Management Corporation’s expenses in an amount up to $5.0 million.

If the Merger Agreement is terminated, we may, under specified circumstances, be required to pay a termination fee of $2.5 million or make a payment of up to $5.0 million in respect of Martin Resource Management Corporation’s expenses. If such termination fee or reimbursement expenses are payable, the payment of any such amount could have an adverse consequence to the financial condition and operations of the party responsible for such payment.

The Merger is a taxable transaction and the resulting tax liability of our common unitholders, if any, will depend on each such common unitholder’s particular situation.

The receipt of cash in exchange for common units of the Partnership pursuant to the Merger will be treated as a taxable sale by such common unitholders for U.S. federal income tax purposes. The amount of ordinary income and capital gain or loss recognized by each common unitholder in the Merger will vary depending on each common unitholder’s particular situation, including:

•the amount of cash received by the common unitholder as consideration in the Merger;

•the adjusted tax basis of the common units exchanged by the common unitholder in the Merger;

•the amount of depreciation and amortization deductions previously allocated to the common unitholder; and

•the amount of any suspended passive losses that may be available to the common unitholder in respect of its common units to offset a portion of any income or gain recognized by the common unitholder.


Item 5.			Other Information

During the ~~nine~~three months ended ~~September~~March 3031, ~~2024~~2025, no director or officer (as defined in Rule 16a-1(f) of the Exchange Act) of the Partnership adopted, modified or terminated a “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.
