Martin Midstream (NASDAQ: MMLP) posts 2025 loss and sets 2026 EBITDA outlook
Martin Midstream Partners L.P. reported a net loss of $14.7 million, or $0.37 per unit, for 2025, compared with a $5.2 million loss in 2024. Revenue edged up to $716.1 million, but Adjusted EBITDA declined to $99.0 million from $110.6 million, reflecting weaker transportation and specialty products performance.
The partnership ended December 31, 2025 with total debt of $439.1 million, liquidity of $31.4 million under its revolver, and a total adjusted leverage ratio of 4.43x. A quarterly cash distribution of $0.005 per unit was declared.
For 2026, management guides to Adjusted EBITDA of $96.5 million, maintenance and turnaround capital of $32.4 million, total capital of $36.5 million, and expected adjusted free cash flow of about $5.8 million, implying another year of modest but positive excess cash after investments.
Positive
- None.
Negative
- Profitability and leverage pressure: 2025 Adjusted EBITDA declined to $99.0 million from $110.6 million, net loss widened to $14.7 million, and the total adjusted leverage ratio increased to 4.43x, while 2026 guidance calls for further EBITDA slippage.
Insights
EBITDA and leverage trends weaken the profile despite positive free cash flow.
Martin Midstream Partners grew 2025 revenue to $716.1 million but saw Adjusted EBITDA fall to $99.0 million from $110.6 million. The drop came mainly from lower transportation and specialty products contributions, while sulfur services stayed flat and terminalling and storage improved.
Net loss widened to $14.7 million, and the total adjusted leverage ratio rose to 4.43x from 3.96x, even as total debt declined slightly to $439.1 million. Interest coverage also slipped to 1.90x, underscoring a tighter debt-service cushion despite stable interest costs around $57.8 million.
Guidance for 2026 calls for $96.5 million of Adjusted EBITDA, below 2025’s level, with higher maintenance and turnaround capital of $32.4 million. Management still targets adjusted free cash flow of about $5.8 million, after $4.1 million of growth capex, but actual outcomes will depend on execution across segments and cost control.
