​ Revolving Credit Facility On December 19, 2019, Hudson Technologies Company (“HTC”), Hudson Holdings, Inc. (“Holdings”) and Aspen Refrigerants, Inc. (“ARI”), as borrowers (collectively, the “Borrowers”), and Hudson Technologies, Inc. (the “Company”) as a guarantor, became obligated under a Credit Agreement (the “Wells Fargo Facility”) with Wells Fargo Bank, as administrative agent and lender (“Agent” or “Wells Fargo”) and such other lenders as may thereafter become a party to the Wells Fargo Facility. The Wells Fargo Facility was amended and restated on March 2, 2022 (see Note 14). Under the terms of the Wells Fargo Facility, the Borrowers could borrow, from time to time, up to $60 million at any time consisting of revolving loans in a maximum amount up to the lesser of $60 million and a borrowing base that was calculated based on the outstanding amount of the Borrowers’ eligible receivables and eligible inventory, as described in the Wells Fargo Facility. The Wells Fargo Facility also contained a sublimit of $5 million for swing line loans and $2 million for letters of credit. Amounts borrowed under the Wells Fargo Facility were used by the Borrowers to repay existing revolving indebtedness under its prior revolving credit facility, repay certain principal amounts under the Term Loan Facility (as defined below), and for working capital needs, certain permitted acquisitions, and to reimburse drawings under letters of credit. Interest on loans under the Wells Fargo Facility was payable in arrears on the first day of each month. Interest charges with respect to loans were computed on the actual principal amount of loans outstanding during the month at a rate per annum equal to (A) with respect to Base Rate loans, the sum of (i) a rate per annum equal to the higher of (1) the federal funds rate plus 0.5%, (2) one month LIBOR plus 1.0%, and (3) the prime commercial lending rate of Wells Fargo, plus (ii) between 1.25% and 1.75% depending on average monthly undrawn availability and (B) with respect to LIBOR rate loans, the sum of the LIBOR rate plus between 2.25% and 2.75% depending on average monthly undrawn availability. In connection with the closing of the Wells Fargo Facility, the Company also entered into a Guaranty and Security Agreement, dated as of December 19, 2019 (the “Revolver Guaranty and Security Agreement”), pursuant to which the Company and certain subsidiaries unconditionally guaranteed the payment and performance of all obligations owing by Borrowers to Wells Fargo, as Agent for the benefit of the revolving lenders. Pursuant to the Revolver Guaranty and Security Agreement, Borrowers, the Company and certain other subsidiaries granted to the Agent, for the benefit of the Wells Fargo Facility lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets. The Revolver Guaranty and Security Agreement also provided that the Agent shall receive the right to dominion over certain of the Borrowers’ bank accounts in the event of an Event of Default under the Wells Fargo Facility, or if undrawn availability under the Wells Fargo Facility falls below $9 million at any time. The Wells Fargo Facility contained a financial covenant requiring the Company to maintain at all times minimum liquidity (defined as availability under the Wells Fargo Facility plus unrestricted cash) of at least $5 million, of which at least $3 million must be derived from availability. The Wells Fargo Facility also contained a springing covenant, which took effect only upon a failure to maintain undrawn availability of at least $7.5 million, requiring the Company to maintain a Fixed Charge Coverage Ratio (FCCR) of not less than 1.00 to 1.00, as of the end of each trailing period of twelve consecutive fiscal months commencing with the month prior to the triggering of the covenant. The FCCR (as defined in the Wells Fargo Facility) is the ratio of (a) EBITDA for such period, minus unfinanced capital expenditures made during such period, to (b) the aggregate amount of (i) interest expense required to be paid (other than interest paid-in-kind, amortization of financing fees, and other non-cash interest expense) during such period, (ii) scheduled principal payments (but excluding principal payments relating to outstanding revolving loans under the Wells Fargo Facility), (iii) all net federal, state, and local income taxes required to be paid during such period (provided, that any tax refunds received shall be applied to the period in which the cash outlay for such taxes was made), (iv) all restricted payments paid (as defined in the Wells Fargo Facility) during such period, and (v) to the extent not otherwise deducted from EBITDA for such period, all payments required to be made during such period in respect of any funding deficiency or funding shortfall with respect to any pension plan. The FCCR covenant ceases after the Borrowers have been in compliance therewith for two consecutive months. The Wells Fargo Facility also contained customary non-financial covenants relating to the Company and the Borrowers, including limitations on Borrowers’ ability to pay dividends on common stock or preferred stock, and also includes certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control. The Wells Fargo Facility also contained certain covenants contained in the Fourth Amendment to the Prior Term Loan Facility described below. On April 23, 2020, the Borrowers, the Company and its subsidiaries entered into a First Amendment to Credit Agreement with Wells Fargo (the "First Amendment"). The First Amendment authorized the Company and its subsidiaries to incur up to $2.5 million of indebtedness under the Coronavirus Aid, Relief, and Economic Security Act (the "CARES Act") and contained other provisions relating to the treatment of such proceeds and any potential debt forgiveness, under the Wells Fargo Facility. The commitments under the Wells Fargo Facility were to expire and the full outstanding principal amount of the loans, together with accrued and unpaid interest, would have been due and payable in full on December 19, 2022, unless the commitments are terminated and the outstanding principal amount of the loans were accelerated sooner following an event of default. Prior Term Loan Facility On October 10, 2017, HTC, Holdings, and ARI, as borrowers, and the Company, as guarantor, became obligated under a Term Loan Credit and Security Agreement (as amended, the “Prior Term Loan Facility”) with U.S. Bank National Association, as administrative agent and collateral agent (“Prior Term Loan Agent”) and funds advised by FS Investments and such other lenders as may thereafter become a party to the Term Loan Facility (the “Prior Term Loan Lenders”). The Prior Term Loan Facility was repaid in full and terminated on March 2, 2022 (see Note 14). Under the terms of the Prior Term Loan Facility, the Borrowers immediately borrowed $105 million pursuant to a term loan (the “Prior Term Loan"). The Prior Term Loan was to mature on October 10, 2023. Interest on the Prior Term Loan was generally payable on the earlier of the last day of the interest period applicable to such Eurodollar rate loan and the last day of the Term Loan Facility, as applicable. Interest is payable at the rate per annum of the Eurodollar Rate (as defined in the Term Loan Facility) plus 10.25%. The Borrowers had the option of paying 3.00% interest per annum in kind by adding such amount to the principal of the Prior Term Loans during no more than five fiscal quarters during the term of the Prior Term Loan Facility. Borrowers and the Company granted to the Prior Term Loan Agent, for the benefit of the Prior Term Loan Lenders, a security interest in substantially all of their respective assets, including receivables, equipment, general intangibles (including intellectual property), inventory, subsidiary stock, real property, and certain other assets. The Term Loan Facility contained a financial covenant requiring the Company to maintain a specified total leverage ratio (“TLR”), tested as of the last day of the fiscal quarter. The TLR (as defined in the Term Loan Facility) is the ratio of (a) funded debt as of such day to (b) EBITDA for the four consecutive fiscal quarters ending on the last day of such fiscal quarter. Funded debt (as defined in the Prior Term Loan Facility) includes amounts borrowed under the Wells Fargo Facility and the Prior Term Loan Facility as well as capitalized lease obligations and other indebtedness for borrowed money maturing more than one year from the date of creation thereof. As of December 31, 2021 and 2020, the TLR was approximately 1.93 to 1 and 5.84 to 1, respectively. The Prior Term Loan Facility also contained customary non-financial covenants relating to the Company and the Borrowers, including limitations on their ability to pay dividends on common stock or preferred stock, and also included certain events of default, including payment defaults, breaches of representations and warranties, covenant defaults, cross-defaults to other obligations, events of bankruptcy and insolvency, certain ERISA events, judgments in excess of specified amounts, impairments to guarantees and a change of control. In connection with the closing of the Prior Term Loan Facility, the Company also entered into a Guaranty and Suretyship Agreement, dated as of October 10, 2017 (the “Prior Term Loan Guarantee”), pursuant to which the Company affirmed its unconditional guarantee of the payment and performance of all obligations owing by Borrowers to Prior Term Loan Agent, as agent for the benefit of the Prior Term Loan Lenders. The Prior Term Loan Agent and the Agent have entered into an intercreditor agreement governing the relative priority of their security interests granted by the Borrowers and the Guarantor in the collateral, providing that the Agent would have a first priority security interest in the accounts receivable, inventory, deposit accounts and certain other assets (the “Revolving Credit Priority Collateral”) and the Prior Term Loan Agent would have a first priority security interest in the equipment, real property, capital stock of subsidiaries and certain other assets (the “Prior Term Loan Priority Collateral”). On December 19, 2019, HTC, Holdings and ARI as borrowers and the Company as a guarantor, entered into a Waiver and Fourth Amendment to Term Loan Credit and Security Agreement (the “Fourth Amendment”) with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. The Fourth Amendment waived financial covenant defaults at June 30, 2019 and September 30, 2019 and amended the Term Loan Credit and Security Agreement dated October 10, 2017 (as previously amended, the “Term Loan Facility”) to reset the maximum Total Leverage Ratio covenant contained in the Prior Term Loan Facility at the indicated dates as follows: (i) September 30, 2019 - 15.67:1.00; (ii) December 31, 2019 – 14.54:1.00; (iii) March 31, 2020 – 16.57:1.00; (iv) June 30, 2020 – 10.87:1.00; (v) September 30, 2020 – 8.89:1.00; (vi) December 31, 2020 – 8.89:1.00; (vii) March 31, 2021 – 7.75:1.00; (viii) June 30, 2021 – 7.03:1.00; (ix) September 30, 2021 – 6.08:1.00; and (x) December 31, 2021 – 5.36:1.00. The Fourth Amendment also reset the minimum liquidity requirement (consisting of cash plus undrawn availability on the Borrowers’ revolving loan facility) of $5 million, measured monthly. Furthermore, the Fourth Amendment added a minimum LTM Adjusted EBITDA covenant as of the indicated dates as follows: (i) September 30, 2019 - $7.887 million; (ii) December 31, 2019 – $7.954 million; (iii) March 31, 2020 – $7.359 million; (iv) June 30, 2020 – $11.745 million; (v) September 30, 2020 – $12.021 million; (vi) December 31, 2020 – $12.300 million; (vii) March 31, 2021 –$14.295 million; (viii) June 30, 2021 – $14.566 million; (ix) September 30, 2021 – $15.431 million; and (x) December 31, 2021 – $16.267 million. The Fourth Amendment also (i) continued the limitation on acquisitions and dividends, (ii) required a principal repayment of $14,000,000 upon execution of the Fourth Amendment and (iii) increased the scheduled quarterly principal repayments to $562,000 effective March 31, 2020 and $1,312,000 effective December 31, 2020. The Fourth Amendment also terminated the exit fee payable to the term loan lenders, which would have been payable in full in cash upon the earlier to occur of (x) repayment in full of the term loans, or (y) any acceleration of the term loans. In lieu of the exit fee, the Fourth Amendment reinstated a prepayment premium equal to the following percentages of the principal amount prepaid, depending upon the date of prepayment: (i) through March 31, 2020 – 0.50%; (ii) from April 1, 2020 through March 31, 2021 – 2.50%; and (iii) from April 1, 2021 and thereafter – 5.00%. The Fourth Amendment also added a new covenant providing that in the event of a breach of a financial covenant contained in the Term Loan Facility or any failure to make a required principal repayment (a “Trigger Event”), then on or prior to six months after a Trigger Event, the Company shall commence a process to (x) sell its businesses and/or assets, and/or (y) consummate a refinancing transaction with respect to the Term Loan Facility (a “Transaction”), in each case, subject to enumerated time milestones contained in the Fourth Amendment, and which requires that Transaction shall, in any event, be consummated on or prior to the eighteen (18) month anniversary of the Trigger Event. As closing conditions to the execution and delivery of the Fourth Amendment, the Company was required to: (i) amend its Bylaws in a manner acceptable to the Term Loan Facility lenders; (ii) appoint two new independent directors to the board of directors (the “Special Directors”); and (iii) pay an amendment fee of 0.50% of the amount of the outstanding loans under the Term Loan Facility. On April 23, 2020, HTC, Holdings and ARI as borrowers and the Company as a guarantor, entered into a Fifth Amendment to Term Loan Credit and Security Agreement (the "Fifth Amendment") with U.S. Bank National Association, as collateral agent and administrative agent, and the various lenders thereunder. The Fifth Amendment authorized the Company and its subsidiaries to incur up to $2.5 million of indebtedness under the CARES Act and contained other provisions relating to the treatment of such proceeds and any potential debt forgiveness, under the Prior Term Loan Facility. The Company evaluated the Fourth and Fifth Amendments in accordance with the provisions of Accounting Standards Codification (“ASC”) 470, Debt, to determine if the Amendments were (1) a troubled debt restructuring, and if not, (2) a modification or an extinguishment of debt. The Company concluded that the Fourth Amendment was a troubled debt restructuring for accounting purposes due to the removal of the exit fee; as such, the Company capitalized an additional $0.5 million of deferred financing costs, which are being amortized over the remaining term. The future undiscounted cash flows of the term loan, as amended, exceeded the carrying value, and accordingly, no gain was recognized and no adjustment was made to the carrying value of the debt. The Company was in compliance with all covenants, under the Prior Wells Fargo Facility and the Term Loan Facility, as amended, as of December 31, 2021. The Company's ability to comply with these covenants in future quarters may be affected by events beyond the Company's control, including general economic conditions, weather conditions, regulations and refrigerant pricing. Therefore, we cannot make any assurance that we will continue to be in compliance during future periods. The Company believes that it will be able to satisfy its working capital requirements for the foreseeable future from anticipated cash flows from operations and available funds under the Wells Fargo Facility. Any unanticipated expenses, including, but not limited to, an increase in the cost of refrigerants purchased by the Company, an increase in operating expenses or failure to achieve expected revenues from the Company's RefrigerantSide(R) Services and/or refrigerant sales or additional expansion or acquisition costs that may arise in the future would adversely affect the Company's future capital needs. There can be no assurance that the Company's proposed or future plans will be successful, and as such, the Company may require additional capital sooner than anticipated, which capital may not be available on acceptable terms, or at all. CARES Act Loan On April 23, 2020 the Company received a loan in the amount of $2.475 million from Meridian Bank under the Paycheck Protection Program ("PPP") pursuant to the CARES Act. The loan had a term of two years, was unsecured, and bore interest at a fixed rate of one percent per annum, with the first nine months of principal and interest deferred. As a result of the COVID-19 pandemic, in applying for the loan the Company made a good faith assertion based upon the degree of uncertainty introduced to the capital markets and the industries affecting the Company's customers and the Company's dependency to curtail expenses to fund ongoing operations. The PPP loan proceeds have been used in part to help offset payroll costs as stipulated in the legislation. All or a portion of the PPP loan may be forgiven by the U.S. Small Business Administration ("SBA") upon application by the Company and upon documentation of expenditures in accordance with the SBA requirements. Under the CARES Act, loan forgiveness is available for the sum of documented payroll costs and other covered areas, such as rent payments, mortgage interest and utilities, as applicable. During the third quarter of 2021, the Company received forgiveness of the loan from the SBA, resulting in $2.475 million of Other Income recorded in the Company’s Consolidated Statements of Operations. Vehicle and Equipment Loans The Company has from time to time entered into various vehicle and equipment loans. These loans were payable in 60 monthly payments through July 2021 and bore interest ranging from 0.0% to 8.3%. All such loans have been repaid in full at December 31, 2021. Capital Lease Obligations The Company rents certain equipment with a de minimis net book value at December 31, 2021 under leases which have been classified as capital leases. ​ Scheduled maturities of the Company’s long-term debt and capital lease obligations are as follows: ​
