T E X T G O E S H E R E S U B T E X T I S P L A C E D H E R E 3 USE OF NON-GAAP FINANCIAL MEASURES This presentation includes certain non-GAAP financial measures such as EBITDA and Adjusted EBITDA. These non-GAAP financial measures are not meant to be considered in isolation or as a substitute for results prepared in accordance with accounting principles generally accepted in the United States (GAAP). A reconciliation of non-GAAP financial measures included in this presentation to the most directly comparable financial measure calculated and presented in accordance with GAAP is set forth in the Appendix of this presentation or on our web site at www.martinmidstream.com. The GAAP financial measures most comparable to the 2016 non-GAAP financial measures are not accessible on a forward-looking basis and reconciling information is not available without unreasonable effort. The items that impacted our GAAP financial measures in 2015 and are reflected in our reconciliation of 2015 non-GAAP financial measures are the same types of items that could impact our GAAP financial measures in 2016, but the levels and values of such impact are unknown at this time. MMLP’s management believes that these non-GAAP financial measures provide useful information to investors regarding MMLP’s financial condition and results of operations as they provide another measure of the profitability and ability to service its debt and are considered important measures by financial analysts covering MMLP and its peers.

T E X T G O E S H E R E S U B T E X T I S P L A C E D H E R E 4 FORWARD LOOKING STATEMENTS Statements included that are not historical facts (including any statements concerning plans and objectives of management for future operations or economic performance or assumptions or forecasts related thereto), are forward-looking statements. These statements can be identified by the use of forward-looking terminology including “forecast,” “may,” “believe,” “will,” “expect,” “anticipate,” “estimate,” “continue,” or other similar words. These statements discuss future expectations, contain projections of results of operations or of financial condition or state other “forward-looking” information. We and our representatives may from time to time make other oral or written statements that are also forward-looking statements. These forward-looking statements are based upon management’s current plans, expectations, estimates, assumptions and beliefs concerning future events impacting us and therefore involve a number of risks and uncertainties. We caution that forward-looking statements are not guarantees and that actual results could differ materially from those expressed or implied in the forward-looking statements. Because these forward-looking statements involve risks and uncertainties, actual results could differ materially from those expressed or implied by these forward-looking statements for a number of important reasons. A discussion of these factors, including risks and uncertainties, is set forth in Martin Midstream Partners L.P.’s annual and quarterly reports filed from time to time with the Securities and Exchange Commission. Martin Midstream Partners L.P. expressly disclaims any intention or obligation to revise or update any forward-looking statements whether as a result of new information, future events, or otherwise.
