About Martin Midstream Partners L.P.

Martin Midstream Partners L.P. is a U.S.-listed midstream services partnership traded on the Nasdaq under the symbol MMLP, with operations and corporate roots in the United States. The company is headquartered in Kilgore, Texas, and operates as a master limited partnership controlled through Martin Resource Management Corporation via the general partner structure. The business was formed in 2002 from assets and operations developed by Martin Resource Management, whose predecessor dates back to 1951 as a supplier to drilling-rig contractors.

Its four primary business lines are 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 NGLs, together with blending and packaging services for specialty lubricants and grease. In practical terms, the partnership provides infrastructure and handling services that connect producers, refiners, chemical customers and wholesale buyers across the energy value chain.

Its asset base is concentrated primarily in the Gulf Coast region of the U.S., which gives it proximity to refining, petrochemical and export markets. That geographic focus supports customer relationships and operating efficiency, but also means results can be influenced by regional industrial activity, commodity-linked volumes and transportation demand. The company serves major and independent oil and gas companies, independent refiners, large chemical companies and other bulk purchasers of petroleum-related products.

In February 2026, management reported full-year 2025 Adjusted EBITDA of $99.0 million and fourth-quarter Adjusted EBITDA of $24.8 million, while guiding to $96.5 million of Adjusted EBITDA for 2026 and declaring a quarterly cash distribution of $0.005 per common unit. In September 2025, MMLP also amended and extended its revolving credit facility, pushing maturity to November 2026 and reducing borrowing capacity to $130 million. Those actions suggest continued emphasis on liquidity discipline and capital structure flexibility.
