NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) NOTE 1. NATURE OF OPERATIONS AND BASIS OF PRESENTATION Martin Midstream Partners L.P. (the "Partnership") is a publicly traded limited partnership with a diverse set of operations focused primarily in the Gulf Coast region of the United States ("U.S."). Its four primary business lines include: terminalling, processing, and storage services for petroleum products and by-products; land and marine transportation services for petroleum products and by-products, chemicals, and specialty products; sulfur and sulfur-based products processing, manufacturing, marketing and distribution; and marketing, distribution, and transportation services for natural gas liquids ("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, 2024, filed with the SEC on February 24, 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 adopted ASU 2023-07 and its expanded segment disclosure requirements in compliance with the required adoption guidelines. In December 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, the Partnership will include the additional disclosure required by ASU 2023-09 in its condensed consolidated financial statements. 9 MARTIN MIDSTREAM PARTNERS L.P.

REVENUE The following table disaggregates our revenue by major source: Three Months Ended June 30, Six Months Ended June 30, 2025 2024 2025 2024 Terminalling and storage segment Throughput and storage $ 22,404 $ 22,375 $ 43,953 $ 44,892 $ 22,404 $ 22,375 $ 43,953 $ 44,892 Transportation segment Land transportation $ 38,942 $ 42,860 $ 77,621 $ 85,603 Inland marine transportation 12,678 12,977 24,680 27,300 Offshore marine transportation 2,206 1,839 4,510 3,080 $ 53,826 $ 57,676 $ 106,811 $ 115,983 Sulfur services segment Sulfur product sales $ 8,894 $ 7,521 $ 18,606 $ 13,204 Fertilizer product sales 31,161 26,194 65,930 50,715 Sulfur services 4,073 3,477 8,296 6,954 $ 44,128 $ 37,192 $ 92,832 $ 70,873 Specialty products segment Natural gas liquids product sales $ 32,976 $ 35,435 $ 75,096 $ 73,566 Lubricant product sales 27,342 31,853 54,527 60,047 $ 60,318 $ 67,288 $ 129,623 $ 133,613 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. 10 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) 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 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 the 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. 2025 2026 2027 2028 2029 Thereafter Total Terminalling and storage Throughput and storage $ 22,475 $ 46,117 $ 47,500 $ 48,990 $ 50,393 $ 105,367 $ 320,842 Sulfur services Product sales 7,118 14,237 14,237 — — — 35,592 Service revenues 5,174 9,374 3,153 2,655 2,655 39,161 62,172 Specialty Products NGL product sales 3,404 3,934 — — — — 7,338 Total $ 38,171 $ 73,662 $ 64,890 $ 51,645 $ 53,048 $ 144,528 $ 425,944 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 June 30, 2025, are as follows: 2025 - $ 13,069 ; 2026 - $ 16,053 ; 2027 - $ 12,987 ; 2028 - $ 12,213 ; 2029 - $ 9,909 ; subsequent years - $ 8,587 .

DEBT At June 30, 2025 and December 31, 2024, long-term debt consisted of the following: June 30, 2025 December 31, 2024 $ 150,000 Credit facility at variable interest rate ( 7.94 % 1 weighted average at June 30, 2025), due February 2027 secured by substantially all of the Partnership’s assets, including, without limitation, inventory, accounts receivable, vessels, equipment, fixed assets and the interests in the Partnership’s operating subsidiaries, net of unamortized debt issuance costs of $ 1,765 and $ 2,242 , respectively 2 $ 39,235 $ 51,258 $ 400,000 Senior notes, 11.5 % interest, net of unamortized debt issuance costs of $ 5,214 and $ 6,223 , respectively, including unamortized premium of $ 6,200 and $ 7,400 , respectively, due February 2028, secured 2 388,586 386,377 Total 427,821 437,635 Less: current portion — — Total long-term debt, net of current portion $ 427,821 $ 437,635 1 The interest rate fluctuates based on Adjusted Term SOFR (set on the date of each advance) or the alternate base rate plus an applicable margin. The margin is set every three months. All amounts outstanding at June 30, 2025 were at Adjusted Term SOFR plus an applicable margin of 3.50 %. The applicable margin for revolving loans that are SOFR loans ranges from 2.75 % to 3.75 %, and the applicable margin for revolving loans that are alternate base rate loans ranges from 1.75 % to 2.75 %. The applicable margin for SOFR borrowings effective July 16, 2025, is 3.50 %. The credit facility contains various covenants that limit the Partnership’s ability to make distributions; make certain investments and acquisitions; enter into certain agreements; incur indebtedness; sell assets; and make certain amendments to the Partnership's omnibus agreement with Martin Resource Management Corporation (as amended, the "Omnibus Agreement"). 2 The Partnership was in compliance with all debt covenants as of June 30, 2025 and December 31, 2024. The Partnership paid cash interest in the amount of $ 1,683 and $ 1,585 for the three months ended June 30, 2025 and 2024, respectively. The Partnership paid cash interest in the amount of $ 26,408 and $ 26,238 for the six months ended June 30, 2025 and 2024, respectively. Capitalized interest was $ 45 and $ 291 for the three months ended June 30, 2025 and 2024, respectively. Capitalized interest was $ 45 and $ 443 for the six months ended June 30, 2025 and 2024, respectively. NOTE 6. LEASES The Partnership has numerous operating leases primarily for terminal facilities and transportation and other equipment. The leases generally provide that all expenses related to the facilities and equipment are to be paid by the lessee. Operating lease Right-of-Use assets and operating lease liabilities are recognized based on the present value of lease payments over the lease term at commencement date. Because most of the Partnership's leases do not provide an implicit rate of return, the Partnership uses its imputed collateralized rate based on the information available at commencement date in determining the present value of lease payments. The estimated rate is based on a risk-free rate plus a risk-adjusted margin. Our leases have remaining lease terms of 1 year to 12 years, some of which include options to extend the leases for up to 5 years, and some of which include options to terminate the leases within 1 year. The Partnership includes extension periods in its lease term if, at commencement, it is reasonably likely that the Par tnership will exercise the extension options. 12 MARTIN MIDSTREAM PARTNERS L.P.

NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) NOTE 8. PARTNERS' CAPITAL (DEFICIT) As of June 30, 2025, Partners’ capital (deficit) consisted of 39,055,086 common limited partner units, representing a 98 % partnership interest, and a 2 % general partner interest. Martin Resource Management Corporation, through subsidiaries, owned 7,653,354 of the Partnership's common limited partner units representing approximately 19.6 % of the Partnership's outstanding common limited partner units. 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: 16 MARTIN MIDSTREAM PARTNERS L.P.

All common unit equivalents were antidilutive for the three and six months ended June 30, 2025 because the limited partners were allocated a net loss in these periods. NOTE 9. UNIT BASED AWARDS - LONG-TERM INCENTIVE PLANS The Partnership recognizes compensation cost related to unit-based awards to both employees and non-employees in its consolidated and condensed financial statements in accordance with certain provisions of ASC 718. Amounts recognized in operating expense and selling, general, and administrative expense in the consolidated and condensed financial statements with respect to these plans are as follows: Three Months Ended June 30, Six Months Ended June 30, 2025 2024 2025 2024 Restricted unit Awards Non-employee directors $ 47 $ 49 $ 90 $ 103 Phantom unit Awards Employees 313 1,395 1,106 1,221 Total unit-based compensation expense $ 360 $ 1,444 $ 1,196 $ 1,324 17 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) 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 Board (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 30 th 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 30 th 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 April 20, 2022, the Board 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 Plan On February 11, 2025, the Board and the Compensation Committee approved the Martin Midstream Partners L.P. 2025 Phantom Unit Plan (the “2025 Plan”) to supersede the 2021 Plan, effective as of the same date. The 2025 Plan contains substantially the same terms and conditions as the 2021 Plan. On February 11, 2025, 1,210,000 phantom units and 425,000 phantom unit appreciation rights were granted to employees of the general partner and its affiliates who perform services for the Partnership. The 2025 Plan permits the awards of phantom units and phantom unit appreciation rights 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. Phantom 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 18 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) compensation expense within operating expense and selling, general and administrative expense in the Consolidated and Condensed Statements of Operations. All of the Partnership's phantom unit awards outstanding as of June 30, 2025 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 "Trade and other accounts payable" and "Other long-term obligations" in the Consolidated and Condensed Balance Sheets. At June 30, 2025, the total liability recognized in connection with outstanding phantom unit awards was $ 4,585 , of which $ 1,082 is recorded in Trade and other accounts payable and $ 3,503 is recorded in Other long-term obligations on the Consolidated and Condensed Balance Sheets. At December 31, 2024, the total liability recognized in connection with outstanding phantom unit awards was $ 3,480 , of which $ 1,073 is recorded in Trade and other accounts payable and $ 2,407 is recorded in Other long-term obligations on the Consolidated and Condensed Balance Sheets. As of June 30, 2025, there was a total of $ 5,009 of unrecognized compensation costs related to non-vested phantom unit awards. These costs are expected to be recognized over a remaining life of 1.74 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 June 30, 2025, met the criteria to be treated under equity classification. On February 11, 2025, the Partnership issued 18,000 TBRUs to each of the Partnership's three independent directors under the 2017 LTIP. These restricted common units vest in equal installments of 6,000 units on January 24, 2026, 2027, 2028, and 2029. 19 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) The restricted units are valued at their fair value at the date of grant, which is equal to the market value of common units on such date.

That cost is expected to be recognized over a weighted-average period of 2.70 years. NOTE 10. RELATED PARTY TRANSACTIONS As of June 30, 2025, Martin Resource Management Corporation owns 7,653,354 of the Partnership’s common units representing approximately 19.6 % of the Partnership’s outstanding limited partner units.

The Partnership’s general partner, MMGP, owns a 2 % general partner interest in the Partnership. The Partnership’s general partner’s ability, as general partner, to manage and operate the Partnership, and Martin Resource Management Corporation’s ownership as of June 30, 2025, of approximately 19.6 % of the Partnership’s outstanding limited partnership units, effectively gives Martin Resource Management Corporation the ability to veto some of the Partnership’s actions and to control the Partnership’s management. The following is a description of the Partnership’s material related party agreements and transactions: Omnibus Agreement Omnibus Agreement . The Partnership and its general partner are parties to the Omnibus Agreement dated November 1, 2002, with Martin Resource Management Corporation 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 the Partnership’s use of certain Martin Resource Management Corporation trade names and trademarks.

Services. Under the Omnibus Agreement, Martin Resource Management Corporation provides the Partnership with corporate staff, support services, and administrative services necessary to operate the Partnership’s business.

NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) payments it makes on the Partnership’s behalf or in connection with the operation of the Partnership’s business. There is no monetary limitation on the amount the Partnership is required to reimburse Martin Resource Management Corporation for direct expenses. In addition to the direct expenses, under the Omnibus Agreement, the Partnership is required to reimburse Martin Resource Management Corporation for indirect general and administrative and corporate overhead expenses. Effective January 1, 2025, through December 31, 2025, the Conflicts Committee approved an annual reimbursement amount for indirect expenses of $ 13,536 .

The Omnibus Agreement prohibits the Partnership from entering into any material agreement with Martin Resource Management Corporation without the prior approval of the Conflicts Committee. For purposes of the Omnibus Agreement, the term "material agreements" means any agreement between the Partnership and Martin Resource Management Corporation that requires aggregate annual payments in excess of the then-applicable agreed upon reimbursable amount of indirect general and administrative expenses. Please read "Services" above. License Provisions.

BUSINESS SEGMENTS The Chief Operating Decision Maker ("CODM") is a group of executives, comprised of the Chief Executive Officer, Chief Financial Officer and Chief Operating Officer of the Partnership's general partner. The CODM may use different operating measures to assess operating results and allocate resources among the Partnership's four segments (outlined below), however the measure that is most consistent with the amounts included in the consolidated financial statements is operating income. The CODM utilizes this measure to evaluate the current financial performance and project the future financial performance of each segment to determine the allocation of capital resources. 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. 25 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) The Specialty Products segment earns revenue by providing marketing, distribution, and transportation services for NGLs as well as blending and packaging services for specialty lubricants and greases. NGL revenue is recognized upon the sale of products via truck, rail, or pipeline. For lubricants and greases, revenue is recognized upon their sale by truck or rail.

NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) 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 2026. NOTE 13. 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. June 30, 2025 December 31, 2024 Carrying Value Fair Value Carrying Value Fair Value 2028 Notes $ 388,586 $ 422,684 $ 386,377 $ 436,172 Total $ 388,586 $ 422,684 $ 386,377 $ 436,172 30 MARTIN MIDSTREAM PARTNERS L.P.

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. Selected financial information for DSM is as follows: As of June 30, Three Months Ended June 30, Total Assets Long-Term Debt Members' Equity/Partners' Capital Revenues Net Income (Loss) 2025 DSM Semichem LLC $ 105,437 $ 28,530 $ 60,515 $ — $( 5,909 ) As of December 31, Three Months Ended June 30, Total Assets Long-Term Debt Members' Equity/Partners' Capital Revenues Net Income (Loss) 2024 DSM Semichem LLC $ 105,773 $ 31,700 $ 68,513 $ — $( 672 ) As of June 30, Six Months Ended June 30, Total Assets Long-Term Debt Members' Equity/Partners' Capital Revenues Net Income (Loss) 2025 DSM Semichem LLC $ 105,437 $ 28,530 $ 60,515 $ — $( 7,999 ) 31 MARTIN MIDSTREAM PARTNERS L.P.

CONDENSED CONSOLIDATED FINANCIAL INFORMATION The Partnership's operations are conducted by its operating subsidiaries as it has no independent assets or operations. The Operating Partnership, the Partnership’s wholly-owned subsidiary, and the Partnership's other operating subsidiaries have issued in the past, and may issue in the future, unconditional guarantees of senior or subordinated debt securities of the Partnership. The guarantees that have been issued are full, irrevocable and unconditional and joint and several. In addition, the Operating Partnership may also issue senior or subordinated debt securities which, if issued, will be fully, irrevocably and unconditionally guaranteed by the Partnership. Substantially all of the Partnership's operating subsidiaries are subsidiary guarantors of its Senior Notes and any subsidiaries other than the subsidiary guarantors are minor. NOTE 16. INCOME TAXES Three Months Ended June 30, Six Months Ended June 30, 2025 2024 2025 2024 Provision for income taxes $ 2,084 $ 1,772 $ 3,201 $ 2,568 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 $ 470 were recorded in income tax expense for the three months ended June 30, 2025 and 2024, respectively. Current state income taxes attributable to the Texas margin tax relating to the operation of the Partnership of $ 687 and $ 550 were recorded in income tax expense for the six months ended June 30, 2025 and 2024, respectively. Deferred taxes applicable to the Texas margin tax relating to the operation of the Partnership are immaterial. 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 $ 1,814 and $ 1,302 , related to the operation of the Taxable Subsidiary, for the three months ended June 30, 2025 and 2024, resulted in an effective income tax rate ("ETR") of 64.50 % and 30.68 %, respectively. Total income tax expense of $ 2,514 and $ 2,018 , related to the operation of the Taxable Subsidiary, for the six months ended June 30, 2025 and 2024, resulted in an ETR of 50.84 % and 22.94 %, respectively. The increase in the ETR for the income taxes during the three and six months ended June 30, 2025 was primarily due to an increase in permanent differences and a decrease in income before income taxes, compared to the same period in 2024. The increase in the provision for income taxes for both the three and six months ended June 30, 2025, compared to the same period in 2024, was primarily due to an increase in permanent differences in the current period. A current federal income tax expense of $ 1,514 and $ 786 , related to the operation of the Taxable Subsidiary, was recorded for the three months ended June 30, 2025 and 2024, respectively. A current federal income tax expense of $ 2,235 and $ 1,576 , related to the operation of the Taxable Subsidiary, was recorded for the six months ended June 30, 2025 and 2024, respectively. A current state income tax expense of $ 240 and $ 165 , related to the operation of the Taxable Subsidiary, was recorded for the three months ended June 30, 2025 and 2024, respectively. A current state income tax expense of $ 433 and $ 416 , related to the operation of the Taxable Subsidiary, was recorded for the six months ended June 30, 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. 32 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2025 (Unaudited) 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 related to the MTI temporary differences of $ 60 and $ 351 was recorded for the three months ended June 30, 2025 and 2024, respectively. A deferred tax expense (benefit) related to the MTI temporary differences of $( 154 ) and $ 26 was recorded for the six months ended June 30, 2025 and 2024, respectively. A net deferred tax asset of $ 10,100 and $ 9,946 , related to the cumulative book and tax temporary differences, existed at June 30, 2025 and December 31, 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. NOTE 17. SUBSEQUENT EVENTS Quarterly Distribution. On July 16, 2025, the Partnership declared a quarterly cash distribution of $ 0.005 per common unit for the second quarter of 2025, or $ 0.020 per common unit on an annualized basis, which will be paid on August 14, 2025, to unitholders of record as of August 7, 2025. One Big Beautiful Bill Act. On July 4, 2025, federal legislation commonly referred to as the “One Big Beautiful Bill Act” was enacted, resulting in changes to U.S. federal income tax law.

The Partnership has preliminarily assessed the impact of the legislation and expects an immaterial net increase in income tax expense related to the Partnership's Taxable Subsidiary in the third quarter of 2025. 33
