INTRODUCTION

This Rule 13e-3 Transaction Statement on Schedule 13E-3, together with the exhibits hereto (this “Transaction Statement”), is being filed with the Securities and Exchange Commission (the “SEC”) by (i) Martin Midstream Partners L.P., a Delaware limited partnership (the “Partnership”), (ii) Martin Resource Management Corporation, a Texas corporation (“Parent”), (iii) MMGP Holdings LLC, a Delaware limited liability company (“Holdings”), (iv) Martin Midstream GP LLC, a Delaware limited liability company (the “General Partner”), (v) MRMC Merger Sub LLC, a Delaware limited liability company (“Merger Sub”), (vi) Martin Resource LLC, a Delaware limited liability company (“Resource”), (vii) Cross Oil Refining & Marketing, Inc., a Delaware corporation (“Cross”), (viii) Martin Product Sales LLC, a Texas limited liability company (“Martin Product”), (ix) Senterfitt Holdings Inc., a Texas corporation (“Senterfitt”), (x) Ruben S. Martin, III and (xi) Robert D. Bondurant. Collectively, the persons filing this Transaction Statement are referred to as the “filing persons” and the filing persons other than the Parent are referred to as the “Buyer Filing Parties.”

This Transaction Statement relates to the Agreement and Plan of Merger, dated as of October 3, 2024, by and among Parent, Merger Sub, a wholly owned subsidiary of Parent, the General Partner, which is the general partner of the Partnership, and the Partnership (the “Merger Agreement”). Pursuant to the Merger Agreement, Merger Sub will merge with and into the Partnership, with the Partnership surviving as a wholly owned subsidiary of Parent (the “Merger”). The Merger Agreement provides that, at the effective time of the Merger (the “Effective Time”), each issued and outstanding common unit representing a limited partner interest in the Partnership (each, a “Common Unit”) other than Common Units owned by Parent and its subsidiaries, including the General Partner (each, a “Public Common Unit”), will be converted into the right to receive $4.02 in cash without any interest (the “Merger Consideration”). The General Partner Interest (as defined in the Partnership Agreement (as defined below)) of the Partnership and the Common Units held by Parent or its subsidiaries, as applicable, in each case that are issued and outstanding immediately prior to the Effective Time, will be unaffected by the Merger and will remain issued and outstanding, and no consideration will be delivered in respect thereof. If the Merger is completed, the Common Units will no longer be listed on the Nasdaq Global Select market and the registration of the Common Units with the SEC under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) will be terminated.

The proposed Merger is a “Rule 13e-3 transaction” under the rules of the SEC. As of October 21, 2024, the Buyer Filing Parties owned an aggregate of 10,149,785 Common Units, representing approximately 26% of the outstanding Common Units. Mr. Martin is the Chairman of the Board of Directors of the General Partner and the President and Chief Executive Officer and a Director of Parent, and Mr. Bondurant is the President and Chief Executive Officer of the General Partner and a Director of Parent. Each of the other Buyer Filing Parties may be deemed an affiliate of the Partnership as described in the Proxy Statement (as defined below). Concurrently with the execution of the Merger Agreement, the Partnership entered into Support Agreements with each of (i) Parent, Cross, Resource and Martin Product, (ii) Senterfitt, (iii) Mr. Bondurant and (iv) Mr. Martin (collectively, the “Support Parties”), pursuant to which the Support Parties have agreed to vote or cause the 10,149,785 Common Units held by the Support Parties in the aggregate, representing approximately 26% of the total issued and outstanding Common Units as of October 21, 2024, to be voted in favor of the Merger and the approval of the Merger Agreement (collectively, the “Support Agreements”). The Support Agreements will not be sufficient to approve the Merger and the Merger Agreement on behalf of the holders of the Common Units, without also obtaining additional votes of other holders of Common Units.

The Conflicts Committee (the “Conflicts Committee”) of the Board of Directors of the General Partner (the “GP Board”), consisting of three independent directors that satisfy the requirements for membership on the Conflicts Committee that are set forth in the Third Amended and Restated Agreement of Limited Partnership of the Partnership, dated as of November 23, 2021 (the “Partnership Agreement”), and the Conflicts Committee Charter, has unanimously and in good faith (i) determined that the Merger Agreement and the transactions contemplated by the Merger Agreement and the Support Agreements, including the Merger, are (A) fair and reasonable to the Partnership and the holders of the Public Common Units (other than Senterfitt, Mr. Martin and the other directors and officers of Parent) (the “Partnership Unaffiliated Unitholders”) and (B) in the best interests of the Partnership and the Partnership Unaffiliated Unitholders, (ii) approved (such approval constituting “Special Approval” for all purposes under the Partnership Agreement, including Section 7.9(a) thereof) the Merger Agreement, the Support Agreements and the transactions contemplated by the Merger Agreement and the Support Agreements, including the Merger, (iii) recommended that the GP Board approve the Merger Agreement, the Support Agreements, the execution, delivery and performance of the Merger Agreement and the Support Agreements and the consummation of the transactions contemplated by the Merger Agreement and the Support Agreements, including the Merger, (iv) recommended that the GP Board submit the Merger Agreement and the Merger to a vote of the limited partners of the Partnership (the “Unitholders”), and (v) recommended, and recommended that the GP Board resolve to recommend, approval of the Merger Agreement and the Merger by the Unitholders.

Following the receipt of the recommendation of the Conflicts Committee, the GP Board unanimously and in good faith (i) determined that the Merger Agreement and the transactions contemplated by the Merger Agreement and the Support Agreements, including the Merger, are (A) fair and reasonable to the Partnership and the Partnership Unaffiliated Unitholders and (B) in the best interests of the Partnership and the Partnership Unaffiliated Unitholders, (ii) approved the Merger Agreement, the Support Agreements, the execution, delivery and performance of the Merger Agreement and the Support Agreements and the consummation of the transactions contemplated by the Merger Agreement and the Support Agreements, including the Merger, (iii) authorized and directed that approval of the Merger Agreement and the Merger be submitted to a vote of the Unitholders and (iv) recommended approval of the Merger Agreement and the Merger by the Unitholders.


Completion of the Merger is subject to certain customary conditions, including, among others, approval of the Merger Agreement and the Merger, which requires the affirmative vote of holders of at least a majority of the issued and outstanding Common Units (the “Unitholder Approval”). The Partnership is holding a special meeting of its Unitholders to obtain the Unitholder Approval.

Concurrently with the filing of this Transaction Statement, the Partnership is filing with the SEC a preliminary proxy statement (the “Proxy Statement”) under Section 14(a) of the Exchange Act with respect to the special meeting of Unitholders, at which Unitholders will be asked to consider and vote on the proposal to approve the Merger Agreement and the Merger. A copy of the Proxy Statement is attached hereto as Exhibit (a)(1) and a copy of the Merger Agreement is attached as Annex A to the Proxy Statement. All references in this Transaction Statement to Items numbered 1001 to 1016 are references to Items contained in Regulation M-A under the Act.

Pursuant to General Instruction F to Schedule 13E-3, the information contained in the Proxy Statement, including all annexes thereto, is expressly incorporated herein by reference in its entirety, and responses to each item herein are qualified in their entirety by the information contained in the Proxy Statement and the annexes thereto. The cross-references below are being supplied pursuant to General Instruction G to Schedule 13E-3 and show the location in the Proxy Statement of the information required to be included in response to the items of Schedule 13E-3. As of the date hereof, the Proxy Statement is in preliminary form and is subject to completion. Terms used but not defined in this Transaction Statement shall have the meanings given to them in the Proxy Statement.

While each of the filing persons acknowledges that the Merger is a “Rule 13e-3 transaction” under the rules of the SEC, the filing of this Transaction Statement shall not be construed as an admission by any filing person, or by any affiliate of a filing person, that the Partnership is “controlled” by any of the filing persons and/or their respective affiliates.

All information concerning the Partnership contained in, or incorporated by reference into, this Transaction Statement was supplied by the Partnership. Similarly, all information concerning each other filing person contained in, or incorporated by reference into, this Transaction Statement was supplied by such filing person.

Dear Sharon:

You, Martin Resource Management Corporation (“you” or the “Borrower”) have advised us, Regions Bank and Regions Capital Markets, a division of Regions Bank (“RCM” and, together with Regions Bank, “us,” “we,” or “Regions”) that the Borrower desires to enter into a senior secured credit facility in an aggregate the principal amount of up to $200,000,000 (the “Senior Credit Facility”), as more fully described in the Summary of Principal Terms and Conditions attached hereto as Annex I and by reference made a part hereof (the “Term Sheet;” and together with this letter, the “Commitment Letter”). Regions understands that the proceeds of the Senior Credit Facility will be used to (i) consummate the acquisition (the “Acquisition”) pursuant to an acquisition agreement by and among the Borrower or certain of its subsidiaries and the sellers (together with all exhibits, schedules, and disclosure letters thereto, collectively, the “Acquisition Agreement”) for the purchase of the equity interests of Martin Midstream Partners L.P. (the “Target”) not already owned, directly or indirectly, by the Borrower, (ii) to pay transaction fees, costs and expenses related to the Senior Credit Facility and the Acquisition, and (iii) to fund the ongoing working capital and general corporate needs of the Borrower and its subsidiaries. The date on which definitive credit documentation evidencing the Senior Credit Facility closes is referred to as the “Closing Date”. The Acquisition, the entering into and funding of the Senior Credit Facility and all related transactions are hereinafter collectively referred to as the “Transaction”.

In connection with the foregoing, you have requested that: (i) Regions Bank agree to serve as the sole and exclusive administrative agent (in such capacity, the “Administrative Agent”) for the Senior Credit Facility and provide a commitment to lend up to $200,000,000 of the Senior Credit Facility and (ii) RCM serve as lead arranger and book runner (in such capacities, the “Lead Arranger”) for the Senior Credit Facility, and in such capacities to form a syndicate of financial institutions (together with Regions Bank, the “Lenders”) reasonably acceptable to you for the Senior Credit Facility.

Subject to the terms and conditions in this Commitment Letter (including the Term Sheet), Regions Bank is pleased to confirm its commitment to extend up to $200,000,000 of the Senior Credit Facility to you and its willingness to act as Administrative Agent for the Senior Credit Facility. RCM is also pleased to confirm its willingness to act as Lead Arranger for the Senior Credit Facility.

Annex I

Term Sheet

[Attached]


 
MRMC Summary of Proposed Terms
   
Borrower    Martin Resource Management Corporation and certain subsidiaries
   
Facility    $200MM Credit Facility including a Revolving Line of Credit of up to $200MM and a $20MM Term Loan. The Revolving Line of Credit will be limited to $200MM less the outstanding balance of the Term Loan.
     
Regions share of Facility    $100MM     
     
Maturity    June 27, 2027     
   
Security    All assets including 100% of MMLP partnership units. 84% of partnership units to be released as security upon full repayment of the Term Loan. Subject to additional discussion either 1) Negative pledge on RE with option to perfect on RE assets subject to certain triggers tbd or 2) Mortgage on real property assets.
     
Sublimits    $22.5MM L/C sublimit     
     
     FCCR    Drawn Pricing
     
Revolver Pricing    Anytime Term Loan is outstanding and until such time that T3M Average EA > $40MM    S+350bps
     
     <1.10x    S+300bps
     
     ≥ 1.10x, ≤1.50x    S+250bps
     
     >1.50x    S+225bps
     
Term Loan Pricing    S+600bps     
   
Term Loan Amortization    4 Year Straight Line subject to mandatory prepayments from MMLP Distributions described below.
   
Term Loan Payment Reserves    To the extent that Proforma TTM FCCR is less than 1.1x, a borrowing base reserve will be established as the lesser of $5MM or the remaining Term Loan principal balance due. For clarity, the Term Loan Payment Reserves would be excluded from the calculation of Minimum Excess Availability.
     
Unused Line Fee    37.5 bps     
   
Administrative Fee    Annual fee on anniversary paid to the Agent $50,000
   
MMLP Distributions   

To the extent that TTM MMLP leverage falls below 3.75x, a minimum of 75% of available distributions will be made to MRMC as long as the Term Loan (“TL” remains outstanding). Of the distributions, 70% will pay down the TL and 30% will pay down the revolver as long as Average T3M Excess Availability (“EA”) is less than $45MM. When EA is greater than $45MM, 100% would be against the TL until paid in full.

Selected Wall Street Analyst Commentary (unit prices in actuals) Date of Report & Analyst Comments Recommendation “MMLP has historically traded at a discount to peers, given its capital structure, elevated leverage, and minimal growth; we believe the offer reflects that discount. In our view, the parent company is the natural acquirer and we do not foresee a competing offer from another company, considering the nature of 5/28/24 Sidoti & MMLP’s business and assets.” Company (Risk: Moderate/ $3.00) “MMLP units are up 14% in the last month and 30% year-to-date. In our view, the strong performance likely reflects balance sheet improvement and potential for additional shareholder returns, as did our prior price target.” “Given MRMC is the logical buyer, we would not anticipate any other bidders to come into play and would not expect a material change to the buyout offer. That said, given MMLP's investment in the DSM Semichem JV 5/24/24 Stifel and longer-term prospects associated with the JV, we believe this could drive incremental value for MMLP (Hold / $3.00) unitholders. Overall, given MMLP's core assets were not mainstream midstream assets, and it was a micro-cap company, we believe the assets fit best in private hands.” “Our $4 price target is based on 4x our revised 2025 FCF per share estimate of $0.90 (from $0.92). MMLP 4/22/24 Sidoti & shares trade at a discount to other small-cap energy companies. We contend the valuation gap fails to Company (Risk: Moderate/ $4.00) reflect the repositioning of the company.” “MMLP… not[ed] upside potential for additional customers to utilize the ELSA produced by the JV. [While] potential upside does exist due to the reshoring trend and chip production expansion in the US, we view it as a longer-term opportunity. At this time, we are maintaining our Hold rating and our $3.00 target 4/18/24 price.” Stifel (Hold / $3.00) “MMLP is trading at 4.8x EV/LP EBITDA. Our 5.0x target multiple applied against our LP EBITDA estimate results in a $3.00 target price.” Source: Wall Street Research. 4 Prior to Offer Subsequent to Offer

Selected Wall Street Analyst Commentary (unit prices in actuals) Date of Report & Analyst Comments Recommendation “We suspect investors are jockeying for a boost to the initial offer of $3.05 per unit before the deal closes given the stock has closed above this price since the announcement.” 6/27/24 Sidoti & “Recently, MMLP incurred what we consider to be two minor environmental incidents. On May 15, multiple media sources reported that a barge owned by MMLP collided with the Pelican Island Bridge near Galveston, Company (Risk: Moderate/ $3.00) TX. Earlier this week, MMLP reported a crude oil pipeline spill of approximately 2,000 barrels near the Smackover refinery in Arkansas. While these issues are unfortunate, we do not see either, or both collectively, having a meaningful effect on MMLP.” “MMLP has historically traded at a discount to peers, given its capital structure, elevated leverage, and minimal growth; we believe the offer reflects that discount. In our view, the parent company is the natural acquirer and we do not foresee a competing offer from another company, considering the nature of 5/28/24 Sidoti & MMLP’s business and assets.” Company (Risk: Moderate/ $3.00) “MMLP units are up 14% in the last month and 30% year-to-date. In our view, the strong performance likely reflects balance sheet improvement and potential for additional shareholder returns, as did our prior price target.” “Given MRMC is the logical buyer, we would not anticipate any other bidders to come into play and would not expect a material change to the buyout offer. That said, given MMLP's investment in the DSM Semichem JV 5/24/24 Stifel and longer-term prospects associated with the JV, we believe this could drive incremental value for MMLP (Hold / $3.00) unitholders. Overall, given MMLP's core assets were not mainstream midstream assets, and it was a micro-cap company, we believe the assets fit best in private hands.” “Our $4 price target is based on 4x our revised 2025 FCF per share estimate of $0.90 (from $0.92). MMLP 4/22/24 Sidoti & shares trade at a discount to other small-cap energy companies. We contend the valuation gap fails to Company (Risk: Moderate/ $4.00) reflect the repositioning of the company.” “MMLP… not[ed] upside potential for additional customers to utilize the ELSA produced by the JV. [While] potential upside does exist due to the reshoring trend and chip production expansion in the US, we view it as a longer-term opportunity. At this time, we are maintaining our Hold rating and our $3.00 target 4/18/24 Stifel price.” (Hold / $3.00) “MMLP is trading at 4.8x EV/LP EBITDA. Our 5.0x target multiple applied against our LP EBITDA estimate results in a $3.00 target price.” Source: Wall Street Research.

Disclaimer This presentation, and any supplemental information (written or oral) or other documents provided in connection therewith (collectively, the “materials”), have been developed by and are proprietary of Houlihan Lokey and are provided solely for the information of the Conflicts Committee (the “Committee”) of the Board of Directors (the “Board”) of Martin Midstream GP LLC (the “Company”), to whom such materials are directly addressed and delivered by Houlihan Lokey in connection with the Committee’s consideration of a potential transaction (the “Transaction”) involving the Company. This presentation is incomplete without reference to, and should be considered in conjunction with, any supplemental information provided by and discussions with Houlihan Lokey in connection therewith. Any defined terms used herein shall have the meanings set forth herein, even if such defined terms have been given different meanings elsewhere in the materials. The materials are for discussion purposes only. Houlihan Lokey expressly disclaims any and all liability, whether direct or indirect, in contract or tort or otherwise, to any person in connection with the materials. The materials were prepared for specific persons familiar with the business and affairs of the Company for use in a specific context and were not prepared with a view to public disclosure or to conform with any disclosure standards under any state, federal or international securities laws or other laws, rules or regulations, and none of the Committee, the Company or Houlihan Lokey takes any responsibility for the use of the materials by persons other than the Committee. The materials are provided on a confidential basis solely for the information of the Committee and may not be disclosed, summarized, reproduced, disseminated or quoted or otherwise referred to, in whole or in part, without Houlihan Lokey’s express prior written consent. The materials may not be relied upon by any other person or for any purpose other than as specifically contemplated by a written agreement with Houlihan Lokey. Notwithstanding any other provision herein, the Company (and each employee, representative or other agent of the Company) may disclose to any and all persons without limitation of any kind, the tax treatment and tax structure of any transaction and all materials of any kind (including opinions or other tax analyses, if any) that are provided to the Company relating to such tax treatment and structure. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, the tax treatment of a transaction is the purported or claimed U.S. income or franchise tax treatment of the transaction and the tax structure of a transaction is any fact that may be relevant to understanding the purported or claimed U.S. income or franchise tax treatment of the transaction. If the Company plans to disclose information pursuant to the first sentence of this paragraph, the Company shall inform those to whom it discloses any such information that they may not rely upon such information for any purpose without Houlihan Lokey’s prior written consent. Houlihan Lokey is not an expert on, and nothing contained in the materials should be construed as advice with regard to, legal, accounting, regulatory, insurance, tax or other specialist matters. Houlihan Lokey’s role in reviewing any information was limited solely to performing such a review as it deemed necessary to support its own advice and analysis and was not on behalf of the Committee. The materials necessarily are based on financial, economic, market and other conditions as in effect on, and the information available to Houlihan Lokey as of, the date of the materials. Although subsequent developments may affect the contents of the materials, Houlihan Lokey has not undertaken, and is under no obligation, to update, revise or reaffirm the materials, except as may be expressly contemplated by Houlihan Lokey’s engagement letter. The materials are not intended to provide the sole basis for evaluation of the Transaction and do not purport to contain all information that may be required. The materials do not address the underlying business decision of the Company or any other party to proceed with or effect the Transaction, or the relative merits of the Transaction as compared to any alternative business strategies or transactions that might be available for the Company or any other party. The materials do not constitute any opinion, nor do the materials constitute a recommendation to the Board, the Committee, the Company, any security holder of the Company or any other party as to how to vote or act with respect to any matter relating to the Transaction or otherwise or whether to buy or sell any assets or securities of any company. Houlihan Lokey’s only opinion is the opinion, if any, that is actually delivered to the Committee. In preparing the materials Houlihan Lokey has acted as an independent contractor and nothing in the materials is intended to create or shall be construed as creating a fiduciary or other relationship between Houlihan Lokey and any party. The materials may not reflect information known to other professionals in other business areas of Houlihan Lokey and its affiliates. The preparation of the materials was a complex process involving quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytic methods employed and the adaption and application of these methods to the unique facts and circumstances presented and, therefore, is not readily susceptible to partial analysis or summary description. Furthermore, Houlihan Lokey did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. Accordingly, the analyses contained in the materials must be considered as a whole. Selecting portions of the analyses, analytic methods and factors without considering all analyses and factors could create a misleading or incomplete view. The materials reflect judgments and assumptions with regard to industry performance, general business, economic, regulatory, market and financial conditions and other matters, many of which are beyond the control of the participants in the Transaction. Any estimates of value contained in the materials are not necessarily indicative of actual value or predictive of future results or values, which may be significantly more or less favorable. Any analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which any assets, businesses or securities may actually be sold. The materials do not constitute a valuation opinion or credit rating. In preparing the materials, Houlihan Lokey has not conducted any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (contingent or otherwise) of the Company or any other party and has no obligation to evaluate the solvency of the Company or any other party under any law. CONFIDENTIAL – PRELIMINARY – SUBJECT TO FURTHER REVIEW


Disclaimer All budgets, projections, estimates, financial analyses, reports and other information with respect to operations (including, without limitation, estimates of potential cost savings and synergies) reflected in the materials have been prepared by management of the relevant party or are derived from such budgets, projections, estimates, financial analyses, reports and other information or from other sources, which involve numerous and significant subjective determinations made by management of the relevant party and/or which such management has reviewed and found reasonable. The budgets, projections and estimates (including, without limitation, estimates of potential cost savings and synergies) contained in the materials may or may not be achieved and differences between projected results and those actually achieved may be material. Houlihan Lokey has relied upon representations made by management of the Company and other participants in the Transaction that such budgets, projections and estimates have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of such management (or, with respect to information obtained from public sources, represent reasonable estimates), and Houlihan Lokey expresses no opinion with respect to such budgets, projections or estimates or the assumptions on which they are based. The scope of the financial analysis contained herein is based on discussions with the Committee (including, without limitation, regarding the methodologies to be utilized), and Houlihan Lokey does not make any representation, express or implied, as to the sufficiency or adequacy of such financial analysis or the scope thereof for any particular purpose. Houlihan Lokey has assumed and relied upon the accuracy and completeness of the financial and other information provided to, discussed with or reviewed by it without (and without assuming responsibility for) independent verification of such information, makes no representation or warranty (express or implied) in respect of the accuracy or completeness of such information and has further relied upon the assurances of the Company and other participants in the Transaction that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. In addition, Houlihan Lokey has relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of the Company or any other participant in the Transaction since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to, discussed with or reviewed by Houlihan Lokey that would be material to its analyses, and that the final forms of any draft documents reviewed by Houlihan Lokey will not differ in any material respect from such draft documents. The materials are not an offer to sell or a solicitation of an indication of interest to purchase any security, option, commodity, future, loan or currency. The materials do not constitute a commitment by Houlihan Lokey or any of its affiliates to underwrite, subscribe for or place any securities, to extend or arrange credit, or to provide any other services. In the ordinary course of business, certain of Houlihan Lokey’s affiliates and employees, as well as investment funds in which they may have financial interests or with which they may co-invest, may acquire, hold or sell, long or short positions, or trade or otherwise effect transactions, in debt, equity, and other securities and financial instruments (including loans and other obligations) of, or investments in, the Company, any Transaction counterparty, any other Transaction participant, any other financially interested party with respect to any transaction, other entities or parties that are mentioned in the materials, or any of the foregoing entities’ or parties’ respective affiliates, subsidiaries, investment funds, portfolio companies and representatives (collectively, the “Interested Parties”), or any currency or commodity that may be involved in the Transaction. Houlihan Lokey provides mergers and acquisitions, restructuring and other advisory and consulting services to clients, which may have in the past included, or may currently or in the future include, one or more Interested Parties, for which services Houlihan Lokey has received, and may receive, compensation. Although Houlihan Lokey in the course of such activities and relationships or otherwise may have acquired, or may in the future acquire, information about one or more Interested Parties or the Transaction, or that otherwise may be of interest to the Board, the Committee, or the Company, Houlihan Lokey shall have no obligation to, and may not be contractually permitted to, disclose such information, or the fact that Houlihan Lokey is in possession of such information, to the Board, the Committee, or the Company or to use such information on behalf of the Board, the Committee, or the Company. Houlihan Lokey’s personnel may make statements or provide advice that is contrary to information contained in the materials. CONFIDENTIAL – PRELIMINARY – SUBJECT TO FURTHER REVIEW

Disclaimer This presentation, and any supplemental information (written or oral) or other documents provided in connection therewith (collectively, the “materials”), have been developed by and are proprietary of Houlihan Lokey and are provided solely for the information of the Conflicts Committee (the “Committee”) of the Board of Directors (the “Board”) of Martin Midstream GP LLC (the “Company”), to whom such materials are directly addressed and delivered by Houlihan Lokey in connection with the Committee’s consideration of a potential transaction (the “Transaction”) involving the Company. This presentation is incomplete without reference to, and should be considered in conjunction with, any supplemental information provided by and discussions with Houlihan Lokey in connection therewith. Any defined terms used herein shall have the meanings set forth herein, even if such defined terms have been given different meanings elsewhere in the materials. The materials are for discussion purposes only. Houlihan Lokey expressly disclaims any and all liability, whether direct or indirect, in contract or tort or otherwise, to any person in connection with the materials. The materials were prepared for specific persons familiar with the business and affairs of the Company for use in a specific context and were not prepared with a view to public disclosure or to conform with any disclosure standards under any state, federal or international securities laws or other laws, rules or regulations, and none of the Committee, the Company or Houlihan Lokey takes any responsibility for the use of the materials by persons other than the Committee. The materials are provided on a confidential basis solely for the information of the Committee and may not be disclosed, summarized, reproduced, disseminated or quoted or otherwise referred to, in whole or in part, without Houlihan Lokey’s express prior written consent. The materials may not be relied upon by any other person or for any purpose other than as specifically contemplated by a written agreement with Houlihan Lokey. Notwithstanding any other provision herein, the Company (and each employee, representative or other agent of the Company) may disclose to any and all persons without limitation of any kind, the tax treatment and tax structure of any transaction and all materials of any kind (including opinions or other tax analyses, if any) that are provided to the Company relating to such tax treatment and structure. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, the tax treatment of a transaction is the purported or claimed U.S. income or franchise tax treatment of the transaction and the tax structure of a transaction is any fact that may be relevant to understanding the purported or claimed U.S. income or franchise tax treatment of the transaction. If the Company plans to disclose information pursuant to the first sentence of this paragraph, the Company shall inform those to whom it discloses any such information that they may not rely upon such information for any purpose without Houlihan Lokey’s prior written consent. Houlihan Lokey is not an expert on, and nothing contained in the materials should be construed as advice with regard to, legal, accounting, regulatory, insurance, tax or other specialist matters. Houlihan Lokey’s role in reviewing any information was limited solely to performing such a review as it deemed necessary to support its own advice and analysis and was not on behalf of the Committee. The materials necessarily are based on financial, economic, market and other conditions as in effect on, and the information available to Houlihan Lokey as of, the date of the materials. Although subsequent developments may affect the contents of the materials, Houlihan Lokey has not undertaken, and is under no obligation, to update, revise or reaffirm the materials, except as may be expressly contemplated by Houlihan Lokey’s engagement letter. The materials are not intended to provide the sole basis for evaluation of the Transaction and do not purport to contain all information that may be required. The materials do not address the underlying business decision of the Company or any other party to proceed with or effect the Transaction, or the relative merits of the Transaction as compared to any alternative business strategies or transactions that might be available for the Company or any other party. The materials do not constitute any opinion, nor do the materials constitute a recommendation to the Board, the Committee, the Company, any security holder of the Company or any other party as to how to vote or act with respect to any matter relating to the Transaction or otherwise or whether to buy or sell any assets or securities of any company. Houlihan Lokey’s only opinion is the opinion, if any, that is actually delivered to the Committee. In preparing the materials Houlihan Lokey has acted as an independent contractor and nothing in the materials is intended to create or shall be construed as creating a fiduciary or other relationship between Houlihan Lokey and any party. The materials may not reflect information known to other professionals in other business areas of Houlihan Lokey and its affiliates. The preparation of the materials was a complex process involving quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytic methods employed and the adaption and application of these methods to the unique facts and circumstances presented and, therefore, is not readily susceptible to partial analysis or summary description. Furthermore, Houlihan Lokey did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. Accordingly, the analyses contained in the materials must be considered as a whole. Selecting portions of the analyses, analytic methods and factors without considering all analyses and factors could create a misleading or incomplete view. The materials reflect judgments and assumptions with regard to industry performance, general business, economic, regulatory, market and financial conditions and other matters, many of which are beyond the control of the participants in the Transaction. Any estimates of value contained in the materials are not necessarily indicative of actual value or predictive of future results or values, which may be significantly more or less favorable. Any analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which any assets, businesses or securities may actually be sold. The materials do not constitute a valuation opinion or credit rating. In preparing the materials, Houlihan Lokey has not conducted any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (contingent or otherwise) of the Company or any other party and has no obligation to evaluate the solvency of the Company or any other party under any law. CONFIDENTIAL – PRELIMINARY – SUBJECT TO FURTHER REVIEW


Disclaimer All budgets, projections, estimates, financial analyses, reports and other information with respect to operations (including, without limitation, estimates of potential cost savings and synergies) reflected in the materials have been prepared by management of the relevant party or are derived from such budgets, projections, estimates, financial analyses, reports and other information or from other sources, which involve numerous and significant subjective determinations made by management of the relevant party and/or which such management has reviewed and found reasonable. The budgets, projections and estimates (including, without limitation, estimates of potential cost savings and synergies) contained in the materials may or may not be achieved and differences between projected results and those actually achieved may be material. Houlihan Lokey has relied upon representations made by management of the Company and other participants in the Transaction that such budgets, projections and estimates have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of such management (or, with respect to information obtained from public sources, represent reasonable estimates), and Houlihan Lokey expresses no opinion with respect to such budgets, projections or estimates or the assumptions on which they are based. The scope of the financial analysis contained herein is based on discussions with the Committee (including, without limitation, regarding the methodologies to be utilized), and Houlihan Lokey does not make any representation, express or implied, as to the sufficiency or adequacy of such financial analysis or the scope thereof for any particular purpose. Houlihan Lokey has assumed and relied upon the accuracy and completeness of the financial and other information provided to, discussed with or reviewed by it without (and without assuming responsibility for) independent verification of such information, makes no representation or warranty (express or implied) in respect of the accuracy or completeness of such information and has further relied upon the assurances of the Company and other participants in the Transaction that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. In addition, Houlihan Lokey has relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of the Company or any other participant in the Transaction since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to, discussed with or reviewed by Houlihan Lokey that would be material to its analyses, and that the final forms of any draft documents reviewed by Houlihan Lokey will not differ in any material respect from such draft documents. The materials are not an offer to sell or a solicitation of an indication of interest to purchase any security, option, commodity, future, loan or currency. The materials do not constitute a commitment by Houlihan Lokey or any of its affiliates to underwrite, subscribe for or place any securities, to extend or arrange credit, or to provide any other services. In the ordinary course of business, certain of Houlihan Lokey’s affiliates and employees, as well as investment funds in which they may have financial interests or with which they may co-invest, may acquire, hold or sell, long or short positions, or trade or otherwise effect transactions, in debt, equity, and other securities and financial instruments (including loans and other obligations) of, or investments in, the Company, any Transaction counterparty, any other Transaction participant, any other financially interested party with respect to any transaction, other entities or parties that are mentioned in the materials, or any of the foregoing entities’ or parties’ respective affiliates, subsidiaries, investment funds, portfolio companies and representatives (collectively, the “Interested Parties”), or any currency or commodity that may be involved in the Transaction. Houlihan Lokey provides mergers and acquisitions, restructuring and other advisory and consulting services to clients, which may have in the past included, or may currently or in the future include, one or more Interested Parties, for which services Houlihan Lokey has received, and may receive, compensation. Although Houlihan Lokey in the course of such activities and relationships or otherwise may have acquired, or may in the future acquire, information about one or more Interested Parties or the Transaction, or that otherwise may be of interest to the Board, the Committee, or the Company, Houlihan Lokey shall have no obligation to, and may not be contractually permitted to, disclose such information, or the fact that Houlihan Lokey is in possession of such information, to the Board, the Committee, or the Company or to use such information on behalf of the Board, the Committee, or the Company. Houlihan Lokey’s personnel may make statements or provide advice that is contrary to information contained in the materials. CONFIDENTIAL – PRELIMINARY – SUBJECT TO FURTHER REVIEW

Selected Wall Street Analyst Commentary (unit prices in actuals) Date of Report & Analyst Comments Recommendation “…we would think the Conflicts Committee would have a difficult time getting an opinion letter saying the current MRMC offer was fair since there is a credible bid on the table offering significantly more value in cash 7/11/24 Stifel and is not subject to financing.” (Hold / $4.00) “We continue to view MRMC as the most logical buyer, but believe it will take a higher price.” “We suspect investors are jockeying for a boost to the initial offer of $3.05 per unit before the deal closes given the stock has closed above this price since the announcement.” 6/27/24 “Recently, MMLP incurred what we consider to be two minor environmental incidents. On May 15, multiple media Sidoti & Company sources reported that a barge owned by MMLP collided with the Pelican Island Bridge near Galveston, TX. Earlier this (Risk: Moderate/ $3.00) week, MMLP reported a crude oil pipeline spill of approximately 2,000 barrels near the Smackover refinery in Arkansas. While these issues are unfortunate, we do not see either, or both collectively, having a meaningful effect on MMLP.” “MMLP has historically traded at a discount to peers, given its capital structure, elevated leverage, and minimal growth; we believe the offer reflects that discount. In our view, the parent company is the natural acquirer and we do not foresee a competing offer from another company, considering the nature of MMLP’s business and assets.” 5/28/24 Sidoti & Company (Risk: Moderate/ $3.00) “MMLP units are up 14% in the last month and 30% year-to-date. In our view, the strong performance likely reflects balance sheet improvement and potential for additional shareholder returns, as did our prior price target.” “Given MRMC is the logical buyer, we would not anticipate any other bidders to come into play and would not expect a material change to the buyout offer. That said, given MMLP's investment in the DSM Semichem JV and longer-term 5/24/24 Stifel prospects associated with the JV, we believe this could drive incremental value for MMLP unitholders. Overall, given (Hold / $3.00) MMLP's core assets were not mainstream midstream assets, and it was a micro-cap company, we believe the assets fit best in private hands.” “Our $4 price target is based on 4x our revised 2025 FCF per share estimate of $0.90 (from $0.92). MMLP shares trade 4/22/24 Sidoti & Company at a discount to other small-cap energy companies. We contend the valuation gap fails to reflect the (Risk: Moderate/ $4.00) repositioning of the company.” “MMLP… not[ed] upside potential for additional customers to utilize the ELSA produced by the JV. [While] potential upside does exist due to the reshoring trend and chip production expansion in the US, we view it as a longer- 4/18/24 term opportunity. At this time, we are maintaining our Hold rating and our $3.00 target price.” Stifel (Hold / $3.00) “MMLP is trading at 4.8x EV/LP EBITDA. Our 5.0x target multiple applied against our LP EBITDA estimate results in a $3.00 target price.” Source: Wall Street Research.

Disclaimer This presentation, and any supplemental information (written or oral) or other documents provided in connection therewith (collectively, the “materials”), have been developed by and are proprietary of Houlihan Lokey and are provided solely for the information of the Conflicts Committee (the “Committee”) of the Board of Directors (the “Board”) of Martin Midstream GP LLC (the “Company”), to whom such materials are directly addressed and delivered by Houlihan Lokey in connection with the Committee’s consideration of a potential transaction (the “Transaction”) involving the Company. This presentation is incomplete without reference to, and should be considered in conjunction with, any supplemental information provided by and discussions with Houlihan Lokey in connection therewith. Any defined terms used herein shall have the meanings set forth herein, even if such defined terms have been given different meanings elsewhere in the materials. The materials are for discussion purposes only. Houlihan Lokey expressly disclaims any and all liability, whether direct or indirect, in contract or tort or otherwise, to any person in connection with the materials. The materials were prepared for specific persons familiar with the business and affairs of the Company for use in a specific context and were not prepared with a view to public disclosure or to conform with any disclosure standards under any state, federal or international securities laws or other laws, rules or regulations, and none of the Committee, the Company or Houlihan Lokey takes any responsibility for the use of the materials by persons other than the Committee. The materials are provided on a confidential basis solely for the information of the Committee and may not be disclosed, summarized, reproduced, disseminated or quoted or otherwise referred to, in whole or in part, without Houlihan Lokey’s express prior written consent. The materials may not be relied upon by any other person or for any purpose other than as specifically contemplated by a written agreement with Houlihan Lokey. Notwithstanding any other provision herein, the Company (and each employee, representative or other agent of the Company) may disclose to any and all persons without limitation of any kind, the tax treatment and tax structure of any transaction and all materials of any kind (including opinions or other tax analyses, if any) that are provided to the Company relating to such tax treatment and structure. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, the tax treatment of a transaction is the purported or claimed U.S. income or franchise tax treatment of the transaction and the tax structure of a transaction is any fact that may be relevant to understanding the purported or claimed U.S. income or franchise tax treatment of the transaction. If the Company plans to disclose information pursuant to the first sentence of this paragraph, the Company shall inform those to whom it discloses any such information that they may not rely upon such information for any purpose without Houlihan Lokey’s prior written consent. Houlihan Lokey is not an expert on, and nothing contained in the materials should be construed as advice with regard to, legal, accounting, regulatory, insurance, tax or other specialist matters. Houlihan Lokey’s role in reviewing any information was limited solely to performing such a review as it deemed necessary to support its own advice and analysis and was not on behalf of the Committee. The materials necessarily are based on financial, economic, market and other conditions as in effect on, and the information available to Houlihan Lokey as of, the date of the materials. Although subsequent developments may affect the contents of the materials, Houlihan Lokey has not undertaken, and is under no obligation, to update, revise or reaffirm the materials, except as may be expressly contemplated by Houlihan Lokey’s engagement letter. The materials are not intended to provide the sole basis for evaluation of the Transaction and do not purport to contain all information that may be required. The materials do not address the underlying business decision of the Company or any other party to proceed with or effect the Transaction, or the relative merits of the Transaction as compared to any alternative business strategies or transactions that might be available for the Company or any other party. The materials do not constitute any opinion, nor do the materials constitute a recommendation to the Board, the Committee, the Company, any security holder of the Company or any other party as to how to vote or act with respect to any matter relating to the Transaction or otherwise or whether to buy or sell any assets or securities of any company. Houlihan Lokey’s only opinion is the opinion, if any, that is actually delivered to the Committee. In preparing the materials Houlihan Lokey has acted as an independent contractor and nothing in the materials is intended to create or shall be construed as creating a fiduciary or other relationship between Houlihan Lokey and any party. The materials may not reflect information known to other professionals in other business areas of Houlihan Lokey and its affiliates. The preparation of the materials was a complex process involving quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytic methods employed and the adaption and application of these methods to the unique facts and circumstances presented and, therefore, is not readily susceptible to partial analysis or summary description. Furthermore, Houlihan Lokey did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. Accordingly, the analyses contained in the materials must be considered as a whole. Selecting portions of the analyses, analytic methods and factors without considering all analyses and factors could create a misleading or incomplete view. The materials reflect judgments and assumptions with regard to industry performance, general business, economic, regulatory, market and financial conditions and other matters, many of which are beyond the control of the participants in the Transaction. Any estimates of value contained in the materials are not necessarily indicative of actual value or predictive of future results or values, which may be significantly more or less favorable. Any analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which any assets, businesses or securities may actually be sold. The materials do not constitute a valuation opinion or credit rating. In preparing the materials, Houlihan Lokey has not conducted any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (contingent or otherwise) of the Company or any other party and has no obligation to evaluate the solvency of the Company or any other party under any law. CONFIDENTIAL – PRELIMINARY – SUBJECT TO FURTHER REVIEW


Disclaimer All budgets, projections, estimates, financial analyses, reports and other information with respect to operations (including, without limitation, estimates of potential cost savings and synergies) reflected in the materials have been prepared by management of the relevant party or are derived from such budgets, projections, estimates, financial analyses, reports and other information or from other sources, which involve numerous and significant subjective determinations made by management of the relevant party and/or which such management has reviewed and found reasonable. The budgets, projections and estimates (including, without limitation, estimates of potential cost savings and synergies) contained in the materials may or may not be achieved and differences between projected results and those actually achieved may be material. Houlihan Lokey has relied upon representations made by management of the Company and other participants in the Transaction that such budgets, projections and estimates have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of such management (or, with respect to information obtained from public sources, represent reasonable estimates), and Houlihan Lokey expresses no opinion with respect to such budgets, projections or estimates or the assumptions on which they are based. The scope of the financial analysis contained herein is based on discussions with the Committee (including, without limitation, regarding the methodologies to be utilized), and Houlihan Lokey does not make any representation, express or implied, as to the sufficiency or adequacy of such financial analysis or the scope thereof for any particular purpose. Houlihan Lokey has assumed and relied upon the accuracy and completeness of the financial and other information provided to, discussed with or reviewed by it without (and without assuming responsibility for) independent verification of such information, makes no representation or warranty (express or implied) in respect of the accuracy or completeness of such information and has further relied upon the assurances of the Company and other participants in the Transaction that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. In addition, Houlihan Lokey has relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of the Company or any other participant in the Transaction since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to, discussed with or reviewed by Houlihan Lokey that would be material to its analyses, and that the final forms of any draft documents reviewed by Houlihan Lokey will not differ in any material respect from such draft documents. The materials are not an offer to sell or a solicitation of an indication of interest to purchase any security, option, commodity, future, loan or currency. The materials do not constitute a commitment by Houlihan Lokey or any of its affiliates to underwrite, subscribe for or place any securities, to extend or arrange credit, or to provide any other services. In the ordinary course of business, certain of Houlihan Lokey’s affiliates and employees, as well as investment funds in which they may have financial interests or with which they may co-invest, may acquire, hold or sell, long or short positions, or trade or otherwise effect transactions, in debt, equity, and other securities and financial instruments (including loans and other obligations) of, or investments in, the Company, any Transaction counterparty, any other Transaction participant, any other financially interested party with respect to any transaction, other entities or parties that are mentioned in the materials, or any of the foregoing entities’ or parties’ respective affiliates, subsidiaries, investment funds, portfolio companies and representatives (collectively, the “Interested Parties”), or any currency or commodity that may be involved in the Transaction. Houlihan Lokey provides mergers and acquisitions, restructuring and other advisory and consulting services to clients, which may have in the past included, or may currently or in the future include, one or more Interested Parties, for which services Houlihan Lokey has received, and may receive, compensation. Although Houlihan Lokey in the course of such activities and relationships or otherwise may have acquired, or may in the future acquire, information about one or more Interested Parties or the Transaction, or that otherwise may be of interest to the Board, the Committee, or the Company, Houlihan Lokey shall have no obligation to, and may not be contractually permitted to, disclose such information, or the fact that Houlihan Lokey is in possession of such information, to the Board, the Committee, or the Company or to use such information on behalf of the Board, the Committee, or the Company. Houlihan Lokey’s personnel may make statements or provide advice that is contrary to information contained in the materials. CONFIDENTIAL – PRELIMINARY – SUBJECT TO FURTHER REVIEW

Recent Selected Wall Street Analyst Commentary (unit prices in actuals) Date of Report & Analyst Comments Recommendation 7/30/24 “Our $4 price target reflects the buyout proposals by Nut Tree and Caspian. Sidoti’s policy is to state targets as round Sidoti & Company numbers and, in our view, setting a price target above the latest offer does not seem prudent at this point.” (Risk: Moderate/ $4.00) “Management increased the 2024 CAPEX budget to $58.4 million (from $49.4 million), stalling further improvement to the leverage ratio... The sizeable capital spend resulted in a free cash outflow of $2.9 million, pushing the leverage ratio higher to 3.88x as of June 7/19/24 30 from 3.81x as of March 31.” Sidoti & Company (Risk: Moderate/ $4.00) “Given the higher capital spending this year, management expects to exit the year with a leverage ratio near the current 3.88x, further delaying increased distributions for common unitholders.” “While the company did have some impact from Hurricane Beryl, it was described as minor and non-material from an economic standpoint.” 7/18/24 Stifel (Hold/ $4.00) “MMLP reported 2Q24 results in line with our expectations, despite two incidents occurring in the quarter which negatively impacted the quarter by $2.0 million as the company incurred insurance deductibles with the two events” 7/12/24 Sidoti & Company “We raise our price target to $4 (from $3) to reflect the new buyout proposal.” (Risk: Moderate/ $4.00) Source: Wall Street Research.

This presentation is incomplete without reference to, and should be considered in conjunction with, any supplemental information provided by and discussions with Houlihan Lokey in connection therewith. Any defined terms used herein shall have the meanings set forth herein, even if such defined terms have been given different meanings elsewhere in the materials. The materials are for discussion purposes only. Houlihan Lokey expressly disclaims any and all liability, whether direct or indirect, in contract or tort or otherwise, to any person in connection with the materials. The materials were prepared for specific persons familiar with the business and affairs of the Company for use in a specific context and were not prepared with a view to public disclosure or to conform with any disclosure standards under any state, federal or international securities laws or other laws, rules or regulations, and none of the Committee, the Company or Houlihan Lokey takes any responsibility for the use of the materials by persons other than the Committee. The materials are provided on a confidential basis solely for the information of the Committee and may not be disclosed, summarized, reproduced, disseminated or quoted or otherwise referred to, in whole or in part, without Houlihan Lokey’s express prior written consent. The materials may not be relied upon by any other person or for any purpose other than as specifically contemplated by a written agreement with Houlihan Lokey. Notwithstanding any other provision herein, the Company (and each employee, representative or other agent of the Company) may disclose to any and all persons without limitation of any kind, the tax treatment and tax structure of any transaction and all materials of any kind (including opinions or other tax analyses, if any) that are provided to the Company relating to such tax treatment and structure. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, the tax treatment of a transaction is the purported or claimed U.S. income or franchise tax treatment of the transaction and the tax structure of a transaction is any fact that may be relevant to understanding the purported or claimed U.S. income or franchise tax treatment of the transaction. If the Company plans to disclose information pursuant to the first sentence of this paragraph, the Company shall inform those to whom it discloses any such information that they may not rely upon such information for any purpose without Houlihan Lokey’s prior written consent. Houlihan Lokey is not an expert on, and nothing contained in the materials should be construed as advice with regard to, legal, accounting, regulatory, insurance, tax or other specialist matters. Houlihan Lokey’s role in reviewing any information was limited solely to performing such a review as it deemed necessary to support its own advice and analysis and was not on behalf of the Committee. The materials necessarily are based on financial, economic, market and other conditions as in effect on, and the information available to Houlihan Lokey as of, the date of the materials. Although subsequent developments may affect the contents of the materials, Houlihan Lokey has not undertaken, and is under no obligation, to update, revise or reaffirm the materials, except as may be expressly contemplated by Houlihan Lokey’s engagement letter. The materials are not intended to provide the sole basis for evaluation of the Transaction and do not purport to contain all information that may be required. The materials do not address the underlying business decision of the Company or any other party to proceed with or effect the Transaction, or the relative merits of the Transaction as compared to any alternative business strategies or transactions that might be available for the Company or any other party. The materials do not constitute any opinion, nor do the materials constitute a recommendation to the Board, the Committee, the Company, any security holder of the Company or any other party as to how to vote or act with respect to any matter relating to the Transaction or otherwise or whether to buy or sell any assets or securities of any company. Houlihan Lokey’s only opinion is the opinion, if any, that is actually delivered to the Committee. In preparing the materials Houlihan Lokey has acted as an independent contractor and nothing in the materials is intended to create or shall be construed as creating a fiduciary or other relationship between Houlihan Lokey and any party. The materials may not reflect information known to other professionals in other business areas of Houlihan Lokey and its affiliates. The preparation of the materials was a complex process involving quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytic methods employed and the adaption and application of these methods to the unique facts and circumstances presented and, therefore, is not readily susceptible to partial analysis or summary description. Furthermore, Houlihan Lokey did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. Accordingly, the analyses contained in the materials must be considered as a whole. Selecting portions of the analyses, analytic methods and factors without considering all analyses and factors could create a misleading or incomplete view. The materials reflect judgments and assumptions with regard to industry performance, general business, economic, regulatory, market and financial conditions and other matters, many of which are beyond the control of the participants in the Transaction. Any estimates of value contained in the materials are not necessarily indicative of actual value or predictive of future results or values, which may be significantly more or less favorable. Any analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which any assets, businesses or securities may actually be sold. The materials do not constitute a valuation opinion or credit rating. In preparing the materials, Houlihan Lokey has not conducted any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (contingent or otherwise) of the Company or any other party and has no obligation to evaluate the solvency of the Company or any other party under any law.

The budgets, projections and estimates (including, without limitation, estimates of potential cost savings and synergies) contained in the materials may or may not be achieved and differences between projected results and those actually achieved may be material. Houlihan Lokey has relied upon representations made by management of the Company and other participants in the Transaction that such budgets, projections and estimates have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of such management (or, with respect to information obtained from public sources, represent reasonable estimates), and Houlihan Lokey expresses no opinion with respect to such budgets, projections or estimates or the assumptions on which they are based. The scope of the financial analysis contained herein is based on discussions with the Committee (including, without limitation, regarding the methodologies to be utilized), and Houlihan Lokey does not make any representation, express or implied, as to the sufficiency or adequacy of such financial analysis or the scope thereof for any particular purpose. Houlihan Lokey has assumed and relied upon the accuracy and completeness of the financial and other information provided to, discussed with or reviewed by it without (and without assuming responsibility for) independent verification of such information, makes no representation or warranty (express or implied) in respect of the accuracy or completeness of such information and has further relied upon the assurances of the Company and other participants in the Transaction that they are not aware of any facts or circumstances that would make such information inaccurate or misleading. In addition, Houlihan Lokey has relied upon and assumed, without independent verification, that there has been no change in the business, assets, liabilities, financial condition, results of operations, cash flows or prospects of the Company or any other participant in the Transaction since the respective dates of the most recent financial statements and other information, financial or otherwise, provided to, discussed with or reviewed by Houlihan Lokey that would be material to its analyses, and that the final forms of any draft documents reviewed by Houlihan Lokey will not differ in any material respect from such draft documents. The materials are not an offer to sell or a solicitation of an indication of interest to purchase any security, option, commodity, future, loan or currency. The materials do not constitute a commitment by Houlihan Lokey or any of its affiliates to underwrite, subscribe for or place any securities, to extend or arrange credit, or to provide any other services.

Disclaimer This presentation, and any supplemental information (written or oral) or other documents provided in connection therewith (collectively, the “materials”), have been developed by and are proprietary of Houlihan Lokey and are provided solely for the information of the Conflicts Committee (the “Committee”) of the Board of Directors (the “Board”) of Martin Midstream GP LLC (the “Company”), to whom such materials are directly addressed and delivered by Houlihan Lokey in connection with the Committee’s consideration of a potential transaction (the “Transaction”) involving the Company. This presentation is incomplete without reference to, and should be considered in conjunction with, any supplemental information provided by and discussions with Houlihan Lokey in connection therewith. Any defined terms used herein shall have the meanings set forth herein, even if such defined terms have been given different meanings elsewhere in the materials. The materials are for discussion purposes only. Houlihan Lokey expressly disclaims any and all liability, whether direct or indirect, in contract or tort or otherwise, to any person in connection with the materials. The materials were prepared for specific persons familiar with the business and affairs of the Company for use in a specific context and were not prepared with a view to public disclosure or to conform with any disclosure standards under any state, federal or international securities laws or other laws, rules or regulations, and none of the Committee, the Company or Houlihan Lokey takes any responsibility for the use of the materials by persons other than the Committee. The materials are provided on a confidential basis solely for the information of the Committee and may not be disclosed, summarized, reproduced, disseminated or quoted or otherwise referred to, in whole or in part, without Houlihan Lokey’s express prior written consent. The materials may not be relied upon by any other person or for any purpose other than as specifically contemplated by a written agreement with Houlihan Lokey. Notwithstanding any other provision herein, the Company (and each employee, representative or other agent of the Company) may disclose to any and all persons without limitation of any kind, the tax treatment and tax structure of any transaction and all materials of any kind (including opinions or other tax analyses, if any) that are provided to the Company relating to such tax treatment and structure. However, any information relating to the tax treatment and tax structure shall remain confidential (and the foregoing sentence shall not apply) to the extent necessary to enable any person to comply with securities laws. For this purpose, the tax treatment of a transaction is the purported or claimed U.S. income or franchise tax treatment of the transaction and the tax structure of a transaction is any fact that may be relevant to understanding the purported or claimed U.S. income or franchise tax treatment of the transaction. If the Company plans to disclose information pursuant to the first sentence of this paragraph, the Company shall inform those to whom it discloses any such information that they may not rely upon such information for any purpose without Houlihan Lokey’s prior written consent. Houlihan Lokey is not an expert on, and nothing contained in the materials should be construed as advice with regard to, legal, accounting, regulatory, insurance, tax or other specialist matters. Houlihan Lokey’s role in reviewing any information was limited solely to performing such a review as it deemed necessary to support its own advice and analysis and was not on behalf of the Committee. The materials necessarily are based on financial, economic, market and other conditions as in effect on, and the information available to Houlihan Lokey as of, the date of the materials. Although subsequent developments may affect the contents of the materials, Houlihan Lokey has not undertaken, and is under no obligation, to update, revise or reaffirm the materials, except as may be expressly contemplated by Houlihan Lokey’s engagement letter. The materials are not intended to provide the sole basis for evaluation of the Transaction and do not purport to contain all information that may be required. The materials do not address the underlying business decision of the Company or any other party to proceed with or effect the Transaction, or the relative merits of the Transaction as compared to any alternative business strategies or transactions that might be available for the Company or any other party. The materials do not constitute any opinion, nor do the materials constitute a recommendation to the Board, the Committee, the Company, any security holder of the Company or any other party as to how to vote or act with respect to any matter relating to the Transaction or otherwise or whether to buy or sell any assets or securities of any company. Houlihan Lokey’s only opinion is the opinion, if any, that is actually delivered to the Committee. In preparing the materials Houlihan Lokey has acted as an independent contractor and nothing in the materials is intended to create or shall be construed as creating a fiduciary or other relationship between Houlihan Lokey and any party. The materials may not reflect information known to other professionals in other business areas of Houlihan Lokey and its affiliates. The preparation of the materials was a complex process involving quantitative and qualitative judgments and determinations with respect to the financial, comparative and other analytic methods employed and the adaption and application of these methods to the unique facts and circumstances presented and, therefore, is not readily susceptible to partial analysis or summary description. Furthermore, Houlihan Lokey did not attribute any particular weight to any analysis or factor considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis and factor. Each analytical technique has inherent strengths and weaknesses, and the nature of the available information may further affect the value of particular techniques. Accordingly, the analyses contained in the materials must be considered as a whole. Selecting portions of the analyses, analytic methods and factors without considering all analyses and factors could create a misleading or incomplete view. The materials reflect judgments and assumptions with regard to industry performance, general business, economic, regulatory, market and financial conditions and other matters, many of which are beyond the control of the participants in the Transaction. Any estimates of value contained in the materials are not necessarily indicative of actual value or predictive of future results or values, which may be significantly more or less favorable. Any analyses relating to the value of assets, businesses or securities do not purport to be appraisals or to reflect the prices at which any assets, businesses or securities may actually be sold. The materials do not constitute a valuation opinion or credit rating. In preparing the materials, Houlihan Lokey has not conducted any physical inspection or independent appraisal or evaluation of any of the assets, properties or liabilities (contingent or otherwise) of the Company or any other party and has no obligation to evaluate the solvency of the Company or any other party under any law.


Disclaimer All budgets, projections, estimates, financial analyses, reports and other information with respect to operations (including, without limitation, estimates of potential cost savings and synergies) reflected in the materials have been prepared by management of the relevant party or are derived from such budgets, projections, estimates, financial analyses, reports and other information or from other sources, which involve numerous and significant subjective determinations made by management of the relevant party and/or which such management has reviewed and found reasonable. The budgets, projections and estimates (including, without limitation, estimates of potential cost savings and synergies) contained in the materials may or may not be achieved and differences between projected results and those actually achieved may be material. Houlihan Lokey has relied upon representations made by management of the Company and other participants in the Transaction that such budgets, projections and estimates have been reasonably prepared in good faith on bases reflecting the best currently available estimates and judgments of such management (or, with respect to information obtained from public sources, represent reasonable estimates), and Houlihan Lokey expresses no opinion with respect to such budgets, projections or estimates or the assumptions on which they are based. The scope of the financial analysis contained herein is based on discussions with the Committee (including, without limitation, regarding the methodologies to be utilized), and Houlihan Lokey does not make any representation, express or implied, as to the sufficiency or adequacy of such financial analysis or the scope thereof for any particular purpose.

Executive Summary • Wells Fargo Securities, LLC (“WFS”) is pleased to provide the following materials to the Board of Directors (the “Board”) of Martin Resources Management Corporation (“MRMC”) regarding the potential buyout of the limited partnership units not owned by MRMC (84.3% of the total L.P. units) of Martin Midstream Partners L.P. (“MMLP” or the “Partnership”) • The total value of MMLP units to be purchased is $98.7 million based on closing price of $3.00 per MMLP unit as of 5/23/2024 • Consideration paid to MMLP unitholders would be all cash • The current price per MMLP unit represents a 3.0% premium to the 30-day VWAP ($2.91 per MMLP unit) and represents a 17.1% premium to the 90-trading day closing average ($2.56 per MMLP unit) • MRMC management expects to fund the transaction via an upsized ABL facility at the MRMC level, as well as a new Term Loan facility at the MRMC level • WFS and Regions Bank (“Regions”) have received “green light” internal approvals to fully underwrite the upsized ABL facility and new Term Loan, subject to acceptable definitive documentation and completion of satisfactory due diligence • MRMC Management is seeking Board approval for the initial offer • Submission of a proposal to MMLP will trigger the need to amend Schedule 13D filings for MRMC and Ruben Martin and disclose the offer letter as an attachment Source: FactSet 2


MRMC Strategic Rationale • The appeal of the Master Limited Partnership (“MLP”) structure has diminished with investors • MLPs are experiencing upward pressure to increase distributions / yields in order to stay competitive with interest rate sensitive securities • Additionally, Corporate tax rate cuts have reduced the key tax advantage that MLPs once had over Corporations • As a result, many MLPs have converted to Corporations or have been acquired or absorbed by their General Partner (approximately 35 MLPs today vs 124 in 2015) • MMLP’s relatively small Market Capitalization further limits institutional interest (MMLP has the smallest market capitalization of all remaining Midstream Energy MLPs) • This inadequate trading volume of MMLP Units has resulted in insufficient liquidity for investors, and MMLP Units continue to trade at a discount to peers even as financial results have improved • MMLP’s potential growth opportunities going forward are outside of MLP qualifying income sources 3
