Item 1.01 Entry into a Material Definitive Agreement.
The information provided in Item 2.03 of this Current Report on Form 8-K is hereby incorporated by reference in this Item 1.01
Item 2.03 Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement of a Registrant.
On February 28, 2023, we entered into a five-year senior secured revolving credit agreement (“Amended and Restated Credit Agreement”) with Texas Capital Bank, as administrative agent (the “Lender”), TCBI Securities, Inc., as joint lead arranger and sole book runner and Bank of America, N.A., as joint lead arranger, with an initial commitment of $175 million as of the closing date. Subject to collateral availability, we also have a right to request from the Lender, on an uncommitted basis, an increase of up to $125 million on the aggregate commitment; provided, however, the aggregate commitment amount is not permitted to exceed $300 million. The maturity date of the Amended and Restated Credit Agreement is February 28, 2028. The obligations under the Amended and Restated Credit Agreement are secured by a first priority lien on a variety of our assets, including inventory and accounts receivable as well as a variable number of our leased compressor equipment.
Borrowing Base. At any time before the maturity of the Amended and Restated Credit Agreement, we may draw, repay and re-borrow amounts available under the borrowing base up to the maximum aggregate availability discussed above. Generally, the borrowing base equals the sum of (a) 85% of eligible accounts receivable owed to the Company by investment grade debtors, plus (b) 50% of the eligible inventory, valued at the lower of cost or market value at such time, subject to a cap of this component not to exceed $5 million, plus (c) the lesser of (i) 95% of the net book value of the compressors that the Lender has determined are eligible for the extension of credit, valued at the lower of cost or market value with depreciation not to exceed 25 years, at such time and (ii) 80% of the net liquidation value percentage of the net book value of the eligible compressors that the Lender has determined are eligible for the extension of credit, valued at the lower of cost or market value with depreciation not to exceed 25 years, at such time, plus (d) 80% of the net book value, valued at the lower of cost (excluding any costs for capitalized interest or other non-cash capitalized costs) or market of the eligible new compressor fleet, minus (e) any required availability reserves determined by the Lender in its sole discretion. The Lender may adjust the borrowing base components if material deviations in the collateral are discovered in future audits of the collateral. As of January 31st, 2023, our allowable borrowing base was $134 million.
Interest and Fees. Under the terms of the Amended and Restated Credit Agreement, we have the option of selecting the applicable variable rate for each revolving loan, or portion thereof, of either (a) the Base Rate (as defined below) plus the Applicable Margin, or (b) in the case of a Term SOFR Loan, the Adjusted Term SOFR rate plus the Applicable Margin. "Base Rate" means, for any day, a rate of interest per annum equal to the highest of (a) the prime rate for such day; (b) the sum of the federal funds rate for such day plus 0.50%; and (c) the Adjusted Term SOFR for such day plus 1.00%. The Applicable Margin is determined based upon the leverage ratio as set forth in the most recent compliance certificate received by the Lender for each fiscal quarter from time to time pursuant to the Amended and Restated Credit Agreement. Depending on the leverage ratio, the Applicable Margin can be 2.00% to 2.75% for Base Rate Loans (as defined in the Amended and Restated Credit Agreement) and 3.00% to 3.75% for Term SOFR Loans and for requested letters of credit. In addition, we are required to pay a monthly commitment fee on the daily average unused amount of the commitment while the Amended and Restated Credit Agreement is in effect at an annual rate equal to 0.50% of the unused commitment amount. Accrued interest is payable monthly on outstanding principal amounts and unused commitment fee, provided that accrued interest on Term SOFR Loans is payable at the end of each interest period, but in no event less frequently than quarterly.
Covenants. The Amended and Restated Credit Agreement contains customary representations and warranties, as well as covenants which, among other things, condition or limit our ability to incur additional indebtedness and liens; enter into transactions with affiliates; make acquisitions in excess of certain amounts; pay dividends; redeem or repurchase capital stock or senior notes; make investments or loans; make negative pledges; consolidate, merge or effect asset sales; or change the nature of our business. In addition, we also have certain financial covenants that are applicable during certain trigger periods specified in the Amended and Restated Credit Agreement and require us during such trigger periods to maintain a leverage ratio greater than or equal to 3.50 to 1.00 as of the last day of each fiscal quarter and a fixed charge coverage ratio less than or equal to 1.10 to 1.00 as of the last day of each fiscal quarter.
Events of Default and Acceleration. The Amended and Restated Credit Agreement contains customary events of default for credit facilities of this size and type, and includes, without limitation, payment defaults; defaults in performance of covenants or other agreements contained in the Amended and Restated Credit Agreement and the other transaction documents; inaccuracies in representations and warranties; certain defaults, termination events or similar events; certain defaults with respect to any other Company indebtedness in excess of $1.0 million; certain bankruptcy or insolvency events; the rendering of certain judgments in excess of $1.0 million; certain ERISA events; certain change in control events and the defectiveness of any liens under the secured revolving credit agreement. Obligations outstanding under the Amended and Restated Credit Agreement may be accelerated upon the occurrence of an event of default.

As of January 31st, 2023, we were in compliance with all financial covenants in our Amended and Restated Credit Agreement. At February 28th, 2023, we had $45 million outstanding under the Amended and Restated Credit Agreement.
The description of the Amended and Restated Credit Agreement and Pledge and Security Agreement are qualified in their entirety by reference to the copies thereof filed as Exhibits 10.1 and 10.2 to this Form 8-K, which are incorporated by reference.
Item 7.01. Regulation FD Disclosure.
Commenting on the closing of the new $175 million revolving credit agreement, Stephen Taylor, Interim Chief Executive Officer, said “Historically we have funded our capital expense requirements from internally generated funds from operations, but the increased level of activity and the high cost of large horsepower equipment has driven our need for additional credit. This agreement enables us to fund the capital expenditures required for contracted and prospective contracts. Our prior credit line of $50 million was almost fully utilized and we believe this additional funding will allow us to continue our investments in higher return projects and generate significant rental revenues into the future. In excess of eighty-five percent of the total committed funding is allocated to building or purchasing higher horsepower compressor packages that supports our strategy of continued expansion into that market and approximately sixty percent of the total committed funding is already contracted. We have contracted the majority of this equipment under long-term contracts that we believe will help mitigate the downside risks of industry slowdowns and associated leverage. With this funding, we believe we will be able to continue our growth and further penetrate the strategically important high horsepower markets. Texas Capital Bank originated and led a syndicate of high quality banks to complete this funding and we look forward to working with each of them.”
