Insights

Credit & capital structure analyst

Credit maturity is extended to 2027 while revolving capacity is trimmed and covenants are tightened.

The Second Amendment gives Martin Midstream Partners L.P. more time before its main bank credit facility comes due by pushing the maturity from February 8, 2027 to November 16, 2027. In exchange, the revolving credit availability for Martin Operating Partnership L.P. falls from $150.0 million to $130.0 million, which modestly reduces committed liquidity from this source.

Covenant changes focus on earnings coverage and leverage control. The amendment requires a minimum Interest Coverage Ratio of at least 1.75 to 1.00 starting with the quarter ended March 31, 2025, a maximum Total Leverage Ratio of 4.50 to 1.00 for the quarters ended March 31 and June 30, 2025 and 4.75 to 1.00 thereafter, and a maximum First Lien Leverage Ratio of 1.25 to 1.00 from the quarter ended March 31, 2025 onward. These thresholds frame how much debt and first-lien borrowing the business can carry relative to its earnings under the amended facility.
