First Amendment to Credit Agreement financial

"entered into a First Amendment to Credit Agreement (the “Amendment”)"

Revolving Credit Facility financial

"The Amendment increases the revolving credit facility (the “Revolving Credit Facility”)"

A revolving credit facility is a type of loan that a business can borrow from whenever it needs money, up to a set limit. It’s like having a credit card for companies—allowing them to borrow, pay back, and borrow again as needed, providing flexibility for managing cash flow or funding short-term expenses.

total debt to EBITDA ratio financial

"when the total debt to EBITDA ratio is greater than or equal to 2.50 to 1.00"

commitment fee financial

"introduces leveraged-based adjustments to the annual Revolving Credit Facility commitment fee"

A commitment fee is a charge a lender applies to a borrower for keeping a loan or line of credit available, even before any money is drawn. Think of it as a reservation fee for borrowing power; the borrower pays to ensure funds will be there when needed. Investors care because it adds to a company’s borrowing cost, affects cash flow and liquidity, and can signal lenders’ willingness to extend credit.
