Segment Performance and Operational Highlights
Martin Midstream Partners' diversified business model is reflected in the performance of its four reportable segments:
Terminalling and Storage: This segment generated revenue of $89.07 million and adjusted EBITDA of $8.4 million in Q4 2024. The partnership's terminalling and storage assets are strategically located along the U.S. Gulf Coast, providing storage, handling, and transportation services for a variety of petroleum products and by-products. Key highlights include the stable performance of the shore-based terminals and the Smackover refinery, which operates under a long-term tolling agreement. As of December 31, 2024, MMLP owned or operated 12 marine shore-based terminal facilities and 8 specialty terminal facilities, with aggregate storage capacity of 2.6 million barrels. This includes a naphthenic lubricants refinery in Smackover, Arkansas with a capacity of 7,700 barrels per day, and approximately 2.3 million barrels of underground storage capacity for NGLs.
Transportation: The transportation segment reported revenue of $223.93 million and adjusted EBITDA of $11.6 million in Q4 2024. This business line includes a fleet of land transportation assets, such as trucks and trailers, as well as marine transportation assets, including inland and offshore tank barges and push boats. The segment benefited from strong demand and stable rates in both the land and marine transportation operations. MMLP operates a fleet of approximately 600 trucks and 1,270 tank trailers, which are based across 25 terminals strategically located throughout the U.S. Gulf Coast and Southeastern U.S. The partnership's marine transportation assets include 27 inland marine tank barges, 15 inland push boats, and one articulated offshore tug and barge unit that primarily operate along the Gulf of Mexico and on the U.S. inland waterway system.
Sulfur Services: This segment generated revenue of $129.77 million and adjusted EBITDA of $4.2 million in Q4 2024. The partnership's sulfur services business includes the processing, manufacturing, marketing, and distribution of sulfur and sulfur-based products. Solid performance in the pure sulfur side of the business, driven by higher-than-expected sulfur production volumes from Gulf Coast refineries, offset softer results in the fertilizer product line. MMLP owns and operates five sulfur-based fertilizer production plants and one emulsified sulfur blending plant, located in Texas and Illinois. These plants manufacture primarily sulfur-based fertilizer products for wholesale distributors and industrial users. The partnership also owns a sulfur forming facility in Beaumont, Texas, which is used to convert molten sulfur into solid form prills and granules.
Specialty Products: The specialty products segment reported revenue of $264.85 million and adjusted EBITDA of $4.6 million in Q4 2024. This business unit focuses on the marketing, distribution, and transportation of NGLs, as well as the blending and packaging of specialty lubricants and greases. The segment's performance was impacted by weaker demand for lubricants and greases amid the broader economic slowdown. MMLP owns and operates facilities dedicated to the blending and packaging of private label agricultural, automotive, and industrial lubricants, as well as the manufacture and packaging of commercial and industrial greases. The partnership also sells and distributes NGLs that it primarily purchases from refineries and natural gas processors.
Navigating Challenges and Positioning for the Future
Throughout 2024, Martin Midstream Partners navigated a number of challenges, including the impact of Hurricane Milton on its Tampa terminal and trucking operations, as well as softening demand for certain specialty products. The partnership responded quickly to mitigate the effects of the storm, with minimal long-term impact on its assets and operations.
Looking ahead, Martin Midstream Partners is positioning itself for future growth and success. The partnership recently terminated a merger agreement with its sponsor, Martin Resource Management Corporation, opting instead to continue operating as a standalone publicly traded company. This decision was supported by the partnership's Conflicts Committee and Board of Directors, who believe it will maximize value for unitholders. The termination of the merger agreement resulted in $3.67 million in costs during Q4 2024, contributing to the quarter's net loss of $8.94 million.
In 2025, Martin Midstream Partners is guiding for adjusted EBITDA of $109.1 million, with growth capital expenditures of $9.0 million and maintenance capital expenditures of $25.9 million. The partnership's diversified business model, strong liquidity position, and focus on operational excellence position it well to navigate the current market environment and capitalize on future opportunities in the Gulf Coast midstream space.
For the full year 2024, MMLP is maintaining its adjusted EBITDA guidance of $116.1 million, despite falling short of its Q3 2024 guidance by $1.3 million due to increased expenses related to long-term incentive plans. The partnership has adjusted its forecast slightly for the marine transportation and sulfur services divisions in Q4 2024, with segment-specific adjusted EBITDA guidance available in the presentation attached to their earnings press release.
