Item 7.01. Regulation FD Disclosure.

      On March 10, 2005, Martin Midstream Partners L.P. (the “Partnership”) issued a press release announcing that it plans to publicly release its financial results for the fourth quarter and year ended December 31, 2004, after the market closes on Wednesday, March 16, 2004 and file its Annual Report on Form 10-K with the SEC at the same time. In addition, the Partnership announced that an investors’ conference call to review the fourth quarter and year end results will be held on Friday, March 18, 2005, at 8:30 a.m. Central Time.

      In the press release, the Partnership also announced that it will utilize the 45 day extension authorized by the Securities and Exchange Commission to provide management’s report on the Partnership’s internal control over financial reporting for the fiscal year ended December 31, 2004, together with the Partnership’s independent auditor’s attestation thereon, as required under Section 404 of the Sarbanes-Oxley Act of 2002. The report and the related attestation will be included in an amended Form 10-K to be filed no later than April 30, 2005. The Partnership has spent, and will continue to spend, considerable time and resources analyzing, documenting and testing its system of internal control over financial reporting in preparation of this report. In connection with this process, the Partnership’s management has identified deficiencies, including certain significant deficiencies, that are currently being addressed by management. This analytical, documentation and testing process will be completed prior to the filing of the amended Form 10-K. Based upon testing performed to date, management does not believe that any of the deficiencies currently identified constitute a material weakness in the Partnership’s internal control over financial reporting. As a result of management’s ongoing evaluation of the Partnership’s internal control over financial reporting, additional deficiencies or material weaknesses may be identified or the deficiencies already identified, either alone or in combination with others, may be considered a material weakness.

      A copy of the press release is furnished as an exhibit to this Current Report. In accordance with General Instruction B.2 of Form 8-K, the information set forth herein and in the press release is deemed to be “furnished” and shall not be deemed to be “filed” for purposes of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).
