Credit Facilities On October 26, 2016, the Company established a three-year secured revolving line of credit with CIBC Bank USA (“CIBC”). This line of credit has been amended from time to time. On February 25, 2019, the line of credit was expanded and extended for three years when the Company and its subsidiaries entered into an Amended and Restated Loan and Security Agreement (the “2016 Amended and Restated Loan Agreement”), with CIBC as administrative agent and sole lead arranger and the other financial institutions party thereto (the “Lenders”), providing the Company and its subsidiaries with a $35,000 secured credit facility (as amended to date, the “2016 Credit Facility”). The obligations under the 2016 Credit Facility were secured by, subject to certain exclusions, (i) a first priority security interest in all accounts receivable, inventory, equipment, cash and investment property, and (ii) a mortgage on the Abilene, Texas tower and Pittsburgh, Pennsylvania gearing facilities. On October 29, 2020, the Company executed the First Amendment to the 2016 Amended and Restated Loan Agreement (the “First Amendment”), implementing a payoff of a syndicated lender and a pricing grid based on the Company's trailing twelve month EBITDA under which applicable margins range from 2.25% to 2.75% for LIBOR rate loans and 0.00% and 0.75% for base rate loans, and extending the term of the 2016 Credit Facility to July 31, 2023. On February 23, 2021, the Company executed the Second Amendment to the Amended and Restated Loan Agreement, which waived testing of the fixed charge coverage covenant for the quarters ended March 31, 2021 and June 20, 2021, added a new liquidity covenant applicable to the quarter ended March 31, 2021 and new minimum EBITDA covenants applicable to the quarters ended March 31, 2021 and June 30, 2021. As of September 30, 2021, the Company transitioned back to a fixed charge coverage covenant. On November 8, 2021, the Company executed the Third Amendment to the Amended and Restated Loan Agreement (the “Third Amendment”) which waived the fixed charge coverage ratio default for the quarter ended September 30, 2021, suspended testing of the fixed charge coverage ratio covenant through September 30, 2022, added a minimum EBITDA covenant applicable to the three-month period ending December 31, 2021, the six-month period ending March 31, 2022, the nine-month period ending June 30, 2022 and the twelve-month period ending September 30, 2022 and added a reserve of $5,000 to the Revolving Loan Availability through December 31, 2022. On February 28, 2022, the Company executed the Fourth Amendment to the Amended and Restated Loan Agreement (the “Fourth Amendment”) which reduced the line of credit from $35,000 to $30,000, extended the maturity date until January 31, 2024, waived the minimum EBITDA covenant for the three-month period ended December 31, 2021, revised the fixed charge coverage ratio covenant as of December 31, 2022 for the trailing nine-month period after March 31, 2022, revised the minimum EBITDA covenant applicable to the three-month period ending March 31, 2022, the six-month period ending June 30, 2022 and the nine-month period ending September 30, 2022, revised the liquidity reserve and amended certain other provisions in connection with the discontinuation of LIBOR and replacement with the forward-looking term Secured Overnight Financing Rate (Term SOFR) administered by CME Group, Inc. In conjunction with the 2016 Amended and Restated Loan Agreement, during June 2019, the Company entered into a floating to fixed interest rate swap with CIBC. The swap agreement has a notional amount of $6,000 and a schedule matching that of the underlying loan that synthetically fixes the interest rate on LIBOR borrowings for the entire term of the 2016 Credit Facility at 2.13%, before considering the Company’s risk premium. The interest rate swap is accounted for using mark-to-market accounting. Accordingly, changes in the fair value of the swap each reporting period are adjusted through earnings, which may subject the Company’s results of operations to non-cash volatility. The interest rate swap liability is included in the “Accrued liabilities” line item of the Company’s consolidated financial statements as of December 31, 2021. The interest rate swap expired in February 2022. All obligations outstanding under the 2016 Credit Facility were refinanced by the 2022 Credit Facility on August 5, 2022. On August 4, 2022, the Company entered into a credit agreement (the “2022 Credit Agreement”) with Wells Fargo Bank, National Association, as lender (“Wells Fargo”), providing the Company and its subsidiaries with a $35,000 senior secured revolving credit facility (which may be further increased by up to an additional $10,000 upon the request of the Company and at the sole discretion of Wells Fargo) and a $7,578 senior secured term loan (collectively, the “2022 Credit Facility”). The proceeds of the 2022 Credit Facility are available for general corporate purposes, including strategic growth opportunities. The 2022 Credit Facility replaced the 2016 Credit Facility. In connection with the 2022 Credit Facility, the Company incurred deferred financing costs in the amount of $470 primarily related to the revolving credit loan. These costs are included in the “Other assets” line item of the Company's consolidated financial statements as of December 31, 2022. The 2022 Credit Facility, as amended, contains customary covenants limiting the Company’s and its subsidiaries’ ability to, among other things, incur liens, make investments, incur indebtedness, merge or consolidate with others or dispose of assets, change the nature of its business, and enter into transactions with affiliates. In addition, the 2022 Credit Facility contains financial covenants requiring the Company to have a Fixed Charge Coverage Ratio (i) as of the twelve-month period ending January 31, 2024 through and including June 30, 2024 of 1.0 to 1.0, and (ii) as of each twelve-month period thereafter to be greater than 1.1 to 1.0 and minimum EBITDA (as defined in the 2022 Credit Facility) on a month-end basis of $1,921,000 for the twelve-month period ending March 31, 2023, $3,661,000 for the twelve-month period ending June 30, 2023, $5,876,000 for the twelve-month period ending September 30, 2023, and $9,929,000 for the twelve-month period ending December 31, 2023. The initial term of the revolving credit facility matures August 4, 2027. The term loan also matures on August 4, 2027, with monthly payments based on an 84-month amortization. On February 8, 2023, the Company executed Amendment No. 1 to Credit Agreement and Limited Waiver (the “First Amendment to 2022 Credit Agreement”), which waived the Company's fourth quarter minimum EBITDA (as defined in the 2022 Credit Facility) requirement for the period ended December 31, 2022, amended the Fixed Charge Coverage Ratio (as defined in the 2022 Credit Facility) requirements for the twelve-month period ending January 31, 2024 through and including June 30, 2024 and each twelve-month period thereafter, and amended the minimum EBITDA requirements applicable to the twelve-month periods ending March 31, 2023, June 30, 2023, September 30, 2023, and December 31, 2023. As of December 31, 2022, only $7,217 from the senior secured term loan was outstanding under the 2022 Credit Facility. The Company had $0 drawn on the senior secured revolving credit facility and had the ability to borrow up to $27,351 under the 2022 Credit Facility as of December 31, 2022. As of December 31, 2022, the effective interest rate of the senior secured revolving credit facility was 6.55% and the effective rate of the senior secured term loan was 6.80%. As of December 31, 2021, the effective interest rate of the 2016 Credit Facility was 4.0%. Other In 2016, the Company entered into a $570 unsecured loan agreement with the Development Corporation of Abilene which is included in long-term debt, less current maturities. The loan is forgivable upon the Company meeting and maintaining specific employment thresholds. During each of the years ended December 31, 2022 and 2021, $114 of the loan was forgiven. As of December 31, 2022 and December 31, 2021, the loan balance was $0 and $114, respectively. In addition, the Company has outstanding notes payable for capital expenditures in the amount of $1,094 and $363 as of December 31, 2022 and 2021, respectively, with $88 and $186 included in the “Line of credit and current portion of long-term debt” line item of the Company’s consolidated financial statements as of December 31, 2022 and 2021, respectively. The notes payable have monthly payments that range from $3 to $16 and an interest rate of 4%. The equipment purchased is utilized as collateral for the notes payable. The outstanding notes payable have maturity dates that range from July 2023 to September 2028. On April 15, 2020, the Company received funds under notes and related documents (“PPP Loans”) with CIBC, under the Paycheck Protection Program (the “PPP”) which was established under the CARES Act enacted on March 27, 2020 in response to the COVID-19 pandemic and is administered by the U.S. Small Business Administration (“SBA”). The Company received total proceeds of $9,530 from the PPP Loans and made repayments of $379 on May 13, 2020. Under the terms of the CARES Act, as amended by the Paycheck Protection Program Flexibility Act of 2020 enacted on June 5, 2020, the PPP Loans, and accrued interest and fees are eligible to be forgiven following a period of twenty-four weeks after PPP Loan proceeds are received (the “covered period”) if they are used for qualifying expenses as described in the CARES Act including payroll costs and certain employee benefits (which must equal or exceed 60% of the amount requested to be forgiven), rent, mortgage interest, and utilities. The amount of loan forgiveness is reduced if the borrower terminates employees or significantly reduces salaries during such period, subject to certain exceptions. The Company used at least 60% of the amount of the PPP Loans proceeds to pay for payroll costs and the balance on other eligible qualifying expenses consistent with the terms of the PPP and submitted its forgiveness applications to CIBC during the first quarter of 2021. During the quarter ended June 30, 2021, all loans were forgiven by the SBA and a gain of $9,151 was recorded in “Other income (expense), net” in the Company's condensed consolidated statements of operations.
