Credit & Capital Structure Analyst

Arq extends covenant relief with staged liquidity requirements.

Arq has modified its Revolving Credit Agreement through a fourth amendment with MidCap Funding IV Trust and other lenders. The key change is an extension of prior adjustments to borrowing availability and a revised minimum liquidity covenant over specific dates.

The company must keep at least $2.0 million of liquidity from December 10, 2025 through March 31, 2026, rising to $5.0 million from April 1, 2026 onward. This structure indicates a period of lower required liquidity followed by a higher ongoing threshold once the transition window closes.

The amendment appears administrative and negotiated within the existing lender group, without disclosed changes to facility size or pricing in this excerpt. Future company filings may provide additional context on how these liquidity levels interact with operating needs and borrowing capacity.
