NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2026 (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 greases. 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, 2025, filed with the SEC on February 23, 2026. 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 2024, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures ("ASU 2024-03"), as amended by ASU 2025-01, which requires public entities to disclose disaggregated information about certain income statement line items in the notes to the financial statements. For public entities, ASU 2024-03 is required to be adopted for annual periods beginning after December 15, 2026 and for interim periods beginning after December 15, 2027, with early adoption permitted. The Partnership is currently evaluating the impact that ASU 2024-03 will have on its consolidated and condensed 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, 2026 2025 2026 2025 Terminalling and storage segment Throughput and storage $ 23,743 $ 22,404 $ 46,180 $ 43,953 $ 23,743 $ 22,404 $ 46,180 $ 43,953 Transportation segment Land transportation $ 42,292 $ 38,942 $ 81,204 $ 77,621 Inland marine transportation 13,187 12,678 25,736 24,680 Offshore marine transportation 1,160 2,206 2,506 4,510 $ 56,639 $ 53,826 $ 109,446 $ 106,811 Sulfur services segment Sulfur product sales $ 12,522 $ 8,894 $ 23,326 $ 18,606 Fertilizer product sales 33,295 31,161 68,941 65,930 Sulfur services 4,253 4,073 8,627 8,296 $ 50,070 $ 44,128 $ 100,894 $ 92,832 Specialty products segment Natural gas liquids product sales $ 48,932 $ 32,976 $ 83,345 $ 75,096 Lubricant product sales 34,216 27,342 61,409 54,527 $ 83,148 $ 60,318 $ 144,754 $ 129,623 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, 2026 (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 the 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. 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. 2026 2027 2028 2029 2030 Thereafter Total Terminalling and storage Throughput and storage $ 22,926 $ 47,042 $ 48,454 $ 49,907 $ 51,404 $ 52,947 $ 272,680 Sulfur services Product sales 7,118 14,237 14,237 — — — 35,592 Service revenues 5,904 9,854 9,353 6,953 2,655 36,506 71,225 Specialty Products NGL product sales 575 — — — — — 575 Total $ 36,523 $ 71,133 $ 72,044 $ 56,860 $ 54,059 $ 89,453 $ 380,072 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, 2026, are as follows: 2026 - $ 13,544 ; 2027 - $ 14,464 ; 2028 - $ 12,593 ; 2029 - $ 8,972 ; 2030 - $ 8,398 ; subsequent years - $ 253 .

The margin is set every three months. 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 and alternate base rate borrowings at June 30, 2026 is 3.75 % and 2.75 %, respectively. The applicable margin for SOFR borrowings and alternate base rate borrowings effective July 22, 2026, is 3.75 % and 2.75 %, respectively. 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, 2026 and December 31, 2025. 3 On March 31, 2026, the Partnership, Martin Operating Partnership L.P. (the “Operating Partnership”), a wholly owned subsidiary of the Partnership, and certain of the Partnership’s other subsidiaries entered into a Third Amendment to Fourth Amended and Restated Credit Agreement (the “Third Amendment”) with Royal Bank of Canada, as administrative agent and collateral agent, and the lenders party thereto, which amends the Fourth Amended and Restated Credit Agreement, dated effective as of February 8, 2023 (as previously amended, the “Credit Agreement”). The Third Amendment amended the Credit Agreement to, among other things: • decrease the amount available for the Partnership to borrow under the Credit Agreement on a revolving credit basis from $ 130,000 to $ 115,000 ; and • adjust the financial covenants as described in more detail below: ◦ require the Partnership to maintain a minimum Interest Coverage Ratio (as defined in the Credit Agreement) of at least 1.65 to 1.00 for the fiscal quarters ending March 31, 2026, June 30, 2026, September 30, 2026 and December 31, 2026 and stepping up to 1.75 to 1.00 for the fiscal quarter ending March 31, 2027 and each fiscal quarter thereafter; and ◦ require the Partnership to maintain a maximum Total Leverage Ratio (as defined in the Credit Agreement) of not more than 5.50 to 1.00 for the fiscal quarters ending March 31, 2026, June 30, 2026, September 30, 2026 and December 31, 2026, stepping down to 5.30 to 1.00 for the fiscal quarter ending March 31, 2027, stepping down to 5.25 to 1.00 for the fiscal quarter ending June 30, 2027, and further stepping down to 5.00 to 1.00 for the fiscal quarter ending September 30, 2027 and each fiscal quarter thereafter. The Partnership is in compliance with all debt covenants as of June 30, 2026, and expects to be in compliance for the next twelve months. 12 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2026 (Unaudited) The Partnership paid cash interest in the amount of $ 1,665 and $ 1,683 for the three months ended June 30, 2026 and 2025, respectively. The Partnership paid cash interest in the amount of $ 26,115 and $ 26,408 for the six months ended June 30, 2026 and 2025, respectively. Capitalized interest was $ 143 and $ 45 for the three months ended June 30, 2026 and 2025, respectively. Capitalized interest was $ 235 and $ 45 for the six months ended June 30, 2026 and 2025, 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 11 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.

NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2026 (Unaudited) NOTE 8. PARTNERS' CAPITAL (DEFICIT) As of June 30, 2026, Partners’ capital (deficit) consisted of 39,124,686 common limited partner units, representing a 98 % partnership interest, and a 2 % general partner interest. Martin Resource Management Corporation, through subsidiaries, owned 7,874,446 of the Partnership's common limited partner units representing approximately 20.1 % 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. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2026 (Unaudited) Three Months Ended June 30, Six Months Ended June 30, 2026 2025 2026 2025 Net income (loss) $ 2,647 $ ( 2,407 ) $ ( 4,113 ) $ ( 3,440 ) Less general partner’s interest in net income (loss): Distributions payable on behalf of general partner interest 4 4 8 8 General partner interest in undistributed income (loss) 49 ( 52 ) ( 90 ) ( 77 ) Less income (loss) allocable to unvested restricted units 12 ( 10 ) ( 14 ) ( 14 ) Limited partners’ interest in net income (loss) $ 2,582 $ ( 2,349 ) $ ( 4,017 ) $ ( 3,357 ) The following are the unit amounts used to compute the basic and diluted earnings per limited partner unit for the periods presented: Three Months Ended June 30, Six Months Ended June 30, 2026 2025 2026 2025 Basic weighted average limited partner units outstanding 38,955,432 38,892,347 38,953,569 38,887,692 Dilutive effect of restricted units issued — — — — Total weighted average limited partner diluted units outstanding 38,955,432 38,892,347 38,953,569 38,887,692 All outstanding units were included in the computation of diluted earnings per unit and weighted based on the number of days such units were outstanding during the periods presented. For the three months ended June 30, 2026, all common unit equivalents were excluded from the computation of diluted earnings per unit because their effect would have been antidilutive under the treasury stock method, as the sum of the assumed proceeds and unrecognized compensation cost per unit exceeded the average market price of the common units for the period. All common unit equivalents were antidilutive for the six months ended June 30, 2026 and for the three and six months ended June 30, 2025 because the limited partners were allocated a net loss in those periods. NOTE 9. UNIT BASED AWARDS - LONG-TERM INCENTIVE PLANS The Partnership recognizes compensation costs 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, 2026 2025 2026 2025 Restricted unit Awards Non-employee directors $ 49 $ 47 $ 94 $ 90 Phantom unit Awards Employees ( 360 ) 313 505 1,106 Total unit-based compensation expense $ ( 311 ) $ 360 $ 599 $ 1,196 17 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2026 (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. These units settled in July of 2025 for $ 1,123 . 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. On July 16, 2025, 1,275,000 phantom units and 420,000 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 awards on the balance sheet date. The fair value of these awards is updated at each balance sheet date and 18 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2026 (Unaudited) changes in the fair value 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. All of the Partnership's phantom unit awards outstanding as of June 30, 2026 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, 2026, the total liability recognized in connection with outstanding phantom unit awards was $ 5,079 , of which $ 2,570 is recorded in Trade and other accounts payable and $ 2,509 is recorded in Other long-term obligations on the Consolidated and Condensed Balance Sheets. At December 31, 2025, the total liability recognized in connection with outstanding phantom unit awards was $ 4,574 , of which $ 2,905 is recorded in Trade and other accounts payable and $ 1,669 is recorded in Other long-term obligations on the Consolidated and Condensed Balance Sheets. As of June 30, 2026, there was a total of $ 3,291 of unrecognized compensation costs related to phantom unit awards. These costs are expected to be recognized over a remaining life of 1.66 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 those of a set of its 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, 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, 2026, met the criteria to be treated under equity classification. On February 17, 2026, the Partnership issued 23,200 TBRUs to each of the Partnership's three independent directors under the 2017 LTIP. These restricted common units vest in equal installments of 5,800 units on January 24, 2027, 2028, 2029, and 2030. 19 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2026 (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. A summary of the restricted unit activity for the six months ended June 30, 2026, is provided below: Number of Units Weighted Average Grant-Date Fair Value Per Unit Non-vested, beginning of period 162,738 $ 2.93 Granted (TBRU) 69,600 $ 2.90 Vested ( 63,084 ) $ 2.98 Forfeited — $ — Non-vested, end of period 169,254 $ 2.90 Aggregate intrinsic value, end of period $ 391 A summary of the restricted units’ aggregate intrinsic value (market value at vesting date) and fair value of units vested (market value at date of grant) during the three and six months ended June 30, 2026 and 2025, is provided below: Three Months Ended June 30, Six Months Ended June 30, 2026 2025 2026 2025 Aggregate intrinsic value of units vested $ — $ — $ 184 $ 55 Fair value of units vested — — 188 165 As of June 30, 2026, there was $ 409 of unrecognized compensation cost related to non-vested restricted units. 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, 2026, Martin Resource Management Corporation owns 7,874,446 of the Partnership’s common units representing approximately 20.1 % of the Partnership’s outstanding limited partner units. Martin Resource Management Corporation controls the Partnership's general partner by virtue of its 100 % voting interest in MMGP Holdings, LLC ("Holdings"), the sole member of the Partnership's general partner. 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, 2026, of approximately 20.1 % 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. The Omnibus Agreement was amended on (i) November 25, 2009, to include processing crude oil into finished products including naphthenic lubricants, distillates, asphalt and other intermediate cuts, (ii) October 1, 2012, to permit the Partnership to provide certain lubricant packaging products and services to Martin Resource Management Corporation and (iii) October 17, 2023 to include lubricants and packaging in the Partnership’s definition of business. 20 MARTIN MIDSTREAM PARTNERS L.P.

This restriction does not apply to: • the ownership and/or operation on the Partnership’s behalf of any asset or group of assets owned by it or its affiliates; • any business operated by Martin Resource Management Corporation, including the following: ◦ distributing asphalt, marine fuel and other liquids; ◦ providing shore-based marine services in Texas, Louisiana, Mississippi and Alabama; ◦ operating a crude oil gathering business in Stephens, Arkansas; ◦ providing crude oil gathering and marketing services of base oils, asphalt and distillate products in Smackover, Arkansas; ◦ providing crude oil marketing and transportation from the well head to the end market; • operating an environmental consulting company; • operating a butane optimization business; • supplying employees and services for the operation of the Partnership's business; and • operating, solely for our account, the asphalt facilities owned by the Partnership in each of Hondo, South Houston and Port Neches, Texas and Omaha, Nebraska. • any business that Martin Resource Management Corporation acquires or constructs that has a fair market value of less than $ 5,000 ; • any business that Martin Resource Management Corporation acquires or constructs that has a fair market value of $ 5,000 or more if the Partnership has been offered the opportunity to purchase the business for fair market value and the Partnership declines to do so with the concurrence of the conflicts committee of the Board (the "Conflicts Committee"); and • any business that Martin Resource Management Corporation acquires or constructs where a portion of such business includes a restricted business and the fair market value of the restricted business is $ 5,000 or more and represents less than 20 % of the aggregate value of the entire business to be acquired or constructed; provided that, following completion of the acquisition or construction, the Partnership will be provided the opportunity to purchase the restricted business. 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. The Omnibus Agreement requires the Partnership to reimburse Martin Resource Management Corporation for all direct expenses it incurs or 21 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2026 (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, 2026, through December 31, 2026, the Conflicts Committee approved an annual reimbursement amount for indirect expenses of $ 12,953 . The Partnership reimbursed Martin Resource Management Corporation for $ 3,238 and $ 3,384 of indirect expenses for the three months ended June 30, 2026 and 2025, respectively. The Partnership reimbursed Martin Resource Management Corporation for $ 6,477 and $ 6,768 of indirect expenses for the six months ended June 30, 2026 and 2025, respectively. The Conflicts Committee will review and approve future adjustments in the reimbursement amount for indirect expenses, if any, annually. These indirect expenses are intended to cover the centralized corporate functions Martin Resource Management Corporation provides to the Partnership, such as accounting, treasury, clerical, engineering, legal, billing, information technology, administration of insurance, general office expenses and employee benefit plans and other general corporate overhead functions the Partnership shares with Martin Resource Management Corporation retained businesses. The provisions of the Omnibus Agreement regarding Martin Resource Management Corporation’s services will terminate if Martin Resource Management Corporation ceases to control the general partner of the Partnership. Related-Party Transactions . 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. Under the Omnibus Agreement, Martin Resource Management Corporation has granted the Partnership a nontransferable, nonexclusive, royalty-free right and license to use certain of its trade names and marks, as well as the trade names and marks used by some of its affiliates. Amendment and Termination. The Omnibus Agreement may be amended by written agreement of the parties; provided, however, that it may not be amended without the approval of the Conflicts Committee if such amendment would adversely affect the unitholders. The Omnibus Agreement was amended on (i) November 25, 2009, to permit the Partnership to provide refining services to Martin Resource Management Corporation, (ii) October 1, 2012, to permit the Partnership to provide certain lubricant packaging products and services to Martin Resource Management Corporation and (iii) October 17, 2023 to include lubricants and packaging in the Partnership’s definition of business. Such amendments were approved by the Conflicts Committee. The Omnibus Agreement, other than the indemnification provisions and the provisions limiting the amount for which the Partnership will reimburse Martin Resource Management Corporation for general and administrative services performed on its behalf, will terminate if the Partnership is no longer an affiliate of Martin Resource Management Corporation. Master Transportation Services Agreement Master Transportation Services Agreement. Martin Transport, Inc. ("MTI"), a wholly owned subsidiary of the Partnership, is a party to a master transportation services agreement effective January 1, 2019, with certain wholly owned subsidiaries of Martin Resource Management Corporation.

Marine Agreements Marine Transportation Agreement. The Partnership is a party to a marine transportation agreement effective January 1, 2006, as amended, under which the Partnership provides marine transportation services to Martin Resource Management Corporation on a spot-contract basis at applicable market rates. Effective each January 1, this agreement automatically renews for consecutive one year periods unless either party terminates the agreement by giving written notice to the other party at least 60 days prior to the expiration of the then applicable term. The fees the Partnership charges Martin Resource Management Corporation are based on applicable market rates. Marine Fuel. The Partnership is a party to an agreement with Martin Resource Management Corporation dated November 1, 2002, under which Martin Resource Management Corporation provides the Partnership with marine fuel from its locations in the Gulf of Mexico at a fixed rate in excess of the Platt’s U.S. Gulf Coast Index for #2 Fuel Oil. Under this agreement, the Partnership agreed to purchase all of its marine fuel requirements that occur in the areas serviced by Martin Resource Management Corporation. Terminal Services Agreements 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.

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, 2026 (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, 2026 (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 scheduled to be held August 2 through August 6, 2027. 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, 2026 December 31, 2025 Carrying Value Fair Value Carrying Value Fair Value 2028 Notes $ 393,004 $ 403,525 $ 390,795 $ 415,726 Total $ 393,004 $ 403,525 $ 390,795 $ 415,726 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.

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.

Current state income taxes attributable to the Texas margin tax relating to the operation of the Partnership of $ 282 and $ 687 were recorded in income tax expense for the six months ended June 30, 2026 and 2025, 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 $ 1,633 and $ 1,814 , related to the operation of the Taxable Subsidiary, for the three months ended June 30, 2026 and 2025, resulted in an effective income tax rate ("ETR") of 67.04 % and 64.50 %, respectively. Total income tax expense of $ 2,111 and $ 2,514 , related to the operation of the Taxable Subsidiary, for the six months ended June 30, 2026 and 2025, resulted in an effective income tax rate of 56.44 % and 50.84 %, respectively. The increase in the effective tax rate for the three and six months ended June 30, 2026, compared to the U.S. federal statutory rate of 21%, is primarily due to state income taxes, net of the federal benefit, and nondeductible insurance premiums. The relatively low pre-tax income causes the permanent differences and state taxes to have a proportionately larger effect on the effective tax rate. A current federal income tax expense of $ 984 and $ 1,514 , related to the operation of the Taxable Subsidiary, was recorded for the three months ended June 30, 2026 and 2025, respectively. A current federal income tax expense of $ 1,245 and $ 2,235 , related to the operation of the Taxable Subsidiary, was recorded for the six months ended June 30, 2026 and 2025, respectively. A current state income tax expense of $ 253 and $ 240 , related to the operation of the Taxable Subsidiary, was recorded for the three months ended June 30, 2026 and 2025, respectively. A current state income tax expense of $ 328 and $ 433 , related to the operation of the Taxable Subsidiary, was recorded for the six months ended June 30, 2026 and 2025, 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 32 MARTIN MIDSTREAM PARTNERS L.P. NOTES TO CONSOLIDATED AND CONDENSED FINANCIAL STATEMENTS (Dollars in thousands, except where otherwise indicated) June 30, 2026 (Unaudited) 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 related to the MTI temporary differences of $ 396 and $ 60 was recorded for the three months ended June 30, 2026 and 2025, respectively. A deferred tax expense (benefit) related to the MTI temporary differences of $ 538 and $( 154 ) was recorded for the six months ended June 30, 2026 and 2025, respectively. A net deferred tax asset of $ 8,488 and $ 9,026 , related to the cumulative book and tax temporary differences, existed at June 30, 2026 and December 31, 2025, 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.
