A revolving credit agreement is a flexible loan arrangement where a borrower can borrow, repay, and borrow again up to a set limit, similar to a credit card. It matters because it gives businesses or individuals quick access to funds whenever needed, helping manage cash flow and cover expenses without applying for a new loan each time.

Rolling stock means the movable vehicles used on railways—locomotives, passenger cars, freight wagons and other rail vehicles. For investors it signals a company’s core, high-value assets that generate revenue but also require large upfront cost, regular maintenance and periodic replacement, much like a trucking company’s fleet; changes in the size, condition or utilization of rolling stock can materially affect profits, cash needs and resale value.

FAQ

What did Arq (ARQ) change in its credit agreement on March 31, 2026?

Arq entered a fifth amendment to its revolving Credit, Security and Guaranty Agreement. The changes update covenant mechanics, borrowing availability calculations, and customer concentration limits, potentially affecting how much the company can borrow and on what collateral and account terms.

How does the new availability reserve requirement affect Arq (ARQ)?

The amendment replaces a minimum liquidity covenant with a $2.5 million availability reserve requirement. This reserve, increasing to $5 million in January 2027, must remain unused, effectively reducing immediately accessible borrowing capacity while defining a clearer cushion under the facility.

What changes were made to Arq (ARQ) borrowing availability calculations?

The amendment permits certain eligible equipment and Rolling Stock to be included in the borrowing availability calculation. By counting more asset types as collateral, the facility formula may support higher potential borrowings, subject to the new availability reserve and other existing credit terms.

How did Arq (ARQ) modify its Eligible Accounts definition until August 2026?

The amendment revises the definition of Eligible Accounts to allow higher single-customer concentration until August 2026. This means a larger portion of receivables from one customer can count toward borrowing base calculations during that period, within the lenders’ agreed parameters.

Who are the parties to Arq (ARQ) fifth credit agreement amendment?

The amendment is among Arq, Inc., certain Arq subsidiaries, MidCap Funding IV Trust as agent, and lenders party to the revolving facility. These parties collectively govern the revised covenants, availability calculations, and eligibility definitions under the amended credit agreement.

Where can investors find the full text of Arq (ARQ) Amendment No. 5?

The full Amendment No. 5 is filed as Exhibit 10.1 to the company’s current report. Interested readers can review that exhibit to see detailed covenant language, definitions, and any additional conditions or schedules associated with the revised revolving credit facility.
