EXPLANATORY NOTE





Martin Midstream Partners L.P.'s (the “Partnership”) Annual Report on Form 10-K for the year ended December 31, 2013, initially filed on March 3, 2014 (“Form 10-K”), is revised by this Amendment No. 1 on Form 10-K/A (“Amendment No. 1”) to include the separate financial statements of Cardinal Gas Storage Partners LLC (“Cardinal”), in accordance with Rule 3-09 of Regulation S-X (“Rule 3-09”), as new Exhibit 99.1, in Part IV, Item 15, Exhibits, Financial Statements Schedules (“Item 15”).  Cardinal represents an unconsolidated affiliate, accounted for under the equity method of accounting, which met the conditions of a significant subsidiary pursuant to Rule 3-09(a) and Rule 1-02(w) of Regulation S-X for the three year period ended December 31, 2013.  In accordance with Rule 3-09(b)(1), the separate financial statements of Cardinal are being filed as an amendment to the Partnership's Form 10-K, within 90 days after the end of the Partnership's fiscal year, as they were not available prior to the filing of the Partnership's Form 10-K.





Rule 3-09 of Regulation S-X provides that if a 50%-or-less-owned person accounted for by the equity method meets the first or third condition of the significant subsidiary tests set forth in Rule 1-02(w) of Regulation S-X, substituting 20% for 10%, separate financial statements for that 50%-or-less-owned person shall be filed.  The significance tests are calculated as of the end of each of the Partnership's fiscal years with respect to each fiscal year.





The consent of PricewaterhouseCoopers LLP, independent accountants for Cardinal, is also filed as exhibit 23.3 to this Amendment No. 1 to the Form 10-K.





In addition, this Amendment No. 1 includes new Exhibits 31.1, 31.2, 32.1 and 32.2, certifications of the Chief Executive Officer and Chief Financial Officer, pursuant to Rule 13a-14(a) and (b).





Except as described above, no other amendments are being made to the Form 10-K.  This Amendment No. 1 does not intend to update or modify the disclosure contained in the Partnership's Form 10-K in any way other than as required to reflect the items discussed above and does not reflect events occurring after the March 3, 2014 filing of the Partnership's Form 10-K.  Accordingly this Form 10-K/A should be read in conjunction with the Partnership's other filings.
