Martin Midstream Partners L.P. is a publicly traded limited partnership operating in the oil and gas sector with a focus on the U.S. Gulf Coast. Based in Kilgore, Texas, the company runs four primary lines of business: terminalling, storage and packaging for petroleum products and by-products; natural gas services, including liquids transportation and distribution and natural gas storage; sulfur and sulfur-based products processing, manufacturing and distribution; and land and marine transportation for petroleum products and by-products. Together, these activities position the company as a logistics and processing intermediary in the energy supply chain along regional and national networks.

Its customers include energy producers, marketers and other downstream users who rely on secure handling, storage and transport of crude, refined products and sulfur-related goods. The business model emphasizes integrated services across custody and movement of materials, from receipt and storage to downstream distribution. In December 2025, the company announced a leadership transition with the retirement of Vice President Jeff Posey and the expansion of Michael Lawrence’s responsibilities over sulfur and fertilizer services.
