Summary of Significant Accounting Policies |
Business | Business Hudson Technologies, Inc. (“Hudson” or the “Company”), incorporated under the laws of New York on January 11, 1991, is a refrigerant services company providing innovative solutions to recurring problems within the refrigeration industry. Hudson has proven, reliable programs that meet customer refrigerant needs by providing environmentally sustainable solutions from initial sale of refrigerant gas through recovery, reclamation and reuse, peak operating performance of equipment through energy efficiency and emergency air conditioning and refrigeration system repair, to final refrigerant disposal and carbon credit trading. The Company’s operations consist of one reportable segment. The Company’s products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems, and include refrigerant and industrial gas sales, refrigerant management services consisting primarily of reclamation of refrigerants and RefrigerantSide® Services performed at a customer’s site. RefrigerantSide® Services consist of system decontamination to remove moisture, oils and other contaminants intended to restore systems to designed capacity. As a component of the Company’s products and services, the Company also participates in the generation of carbon offset projects. The Company operates principally through its wholly-owned subsidiary, Hudson Technologies Company. Unless the context requires otherwise, references to the “Company”, “Hudson”, “we”, “us”, “our”, or similar pronouns refer to Hudson Technologies, Inc. and its subsidiaries. In preparing the accompanying consolidated financial statements, and in accordance with Accounting Standards Codification (“ASC”) 855-10 “Subsequent Events”, the Company’s management has evaluated subsequent events through the date that the financial statements were filed. The accompanying unaudited consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial statements and with the instructions of Regulation S-X. Accordingly, they do not include all the information and footnotes required by generally accepted accounting principles for complete financial statements. The financial information included in this quarterly report should be read in conjunction with the Company’s audited financial statements and related notes thereto for the year ended December 31, 2023. Operating results for the three-month period ended March 31, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024. In the opinion of management, all estimates and adjustments considered necessary for a fair presentation have been included and all such adjustments were normal and recurring. AIM Act The United States Environmental Protection Agency (“EPA”) issued several final rules establishing the framework to allocate allowances for virgin production and consumption of hydrofluorocarbon refrigerants (“HFCs”) that currently provide allowances through 2028. The EPA is responsible for the administration of the HFC phase down enacted by Congress under the AIM Act. The AIM Act directs the EPA to address the reduction in virgin HFCs and provides authority to do so in three respects:
| 1) | phase down the production and consumption of listed HFCs,
| 2) | manage these HFCs and their substitutes including reclamation of refrigerants, and
| 3) | facilitate the transition to next-generation technologies.
Congress required that the EPA consider ways to promote reclamation in all phases of its implementation of the AIM Act. The AIM Act introduced a stepdown of 10% from baseline levels in 2022 and 2023, and establishes a cumulative 40% reduction in the baseline for 2024 through 2028. Hudson received allocation allowances for calendar years 2022 and 2023 equal to approximately 1% of the total HFC consumption allowances, with allowances for future periods to be determined at a later date. Reclamation will be critical to maintaining necessary HFC supply levels to ensure an orderly phasedown. Reclamation is not subject to the allowance system or restricted from use. On October 6, 2023, the EPA announced the latest actions to phase down HFCs under the AIM Act:
| 1) | Finalization of the Technology Transition Rule – The first action is a final rule to accelerate the ongoing transition to more efficient and climate-safe technologies in new refrigeration, heating and cooling systems and other products by restricting the use of HFCs where alternatives are already available. The rule, which applies to both imported and domestically manufactured products, bans HFCs in certain equipment and sets a limit on the global warming potentials (GWPs) of the HFCs that can be used in each subsector, with compliance dates ranging from 2025 to 2028.
In December 2023, the EPA announced an interim final rule on this matter, which provides an additional year, until January 1, 2026, for the installation of new residential and light commercial air conditioning systems and heat pump systems that use components manufactured or imported prior to January 1, 2025. Importantly, to qualify for the extended compliance deadline, all components of a system using the higher Global Warming Potential (GWP) HFC must be manufactured or imported prior to January 1, 2025.
| 2) | Proposed Refrigerant Management Rule – The second action is a proposed rule (which was subject to a public comment period that closed in December 2023) to better manage and reuse existing HFCs, including by reducing wasteful leaks from equipment and supporting HFC recycling and reclamation. The proposed rule, which is expected to be finalized during the third quarter of 2024, includes requirements for repairing leaky equipment, use of automatic leak detection systems on large refrigeration systems, use of reclaimed HFCs for certain applications, recovery of HFCs from cylinders before their disposal, and a container tracking system.
Consolidation | Consolidation The consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States, represent all companies of which Hudson directly or indirectly has majority ownership or otherwise controls. Significant intercompany accounts and transactions have been eliminated. The Company’s consolidated financial statements include the accounts of wholly-owned subsidiaries Hudson Holdings, Inc. and Hudson Technologies Company. The Company does not present a statement of comprehensive income as its comprehensive income is the same as its net income.
Fair Value of Financial Instruments | Fair Value of Financial Instruments The carrying values of financial instruments including cash, trade accounts receivable and accounts payable approximate fair value at March 31, 2024 and December 31, 2023, because of the relatively short maturity of these instruments. See Note 2 for further details.
Credit Risk | Credit Risk Financial instruments, which potentially subject the Company to concentrations of credit risk, consist principally of temporary cash investments and trade accounts receivable. The Company maintains its temporary cash investments in highly-rated financial institutions and, at times, the balances exceed FDIC insurance coverage. The Company’s trade accounts receivable are primarily due from companies throughout the United States. The Company reviews each customer’s credit history before extending credit. The Company establishes an allowance for credit losses. In accordance with the “expected credit loss” model, the carrying amount of accounts receivable is reduced by a valuation allowance that reflects the Company’s best estimate of the amounts that it does not expect to collect. In addition to reviewing delinquent accounts receivable, the Company considers many factors in estimating its reserve, including types of customers and their credit worthiness, experience and historical data adjusted for current conditions. The carrying value of the Company’s accounts receivable is reduced by the established allowance for credit losses. The allowance for credit losses includes any accounts receivable balances that are determined to be uncollectible, along with a general reserve for the remaining accounts receivable balances. The Company adjusts its reserves based on factors that affect the collectability of the accounts receivable balances. For the three month period ended March 31, 2024 there was one customer accounting for greater than 10% of the Company’s revenues and at March 31, 2024 there were $11.9 million of accounts receivable from this customer. For the three month period ended March 31, 2023 there was one customer accounting for greater than 10% of the Company’s revenues and at March 31, 2023 there were $9.4 million of accounts receivable from this customer. The loss of a principal customer or a decline in the economic prospects of and/or a reduction in purchases of the Company’s products or services by any such customer could have a material adverse effect on the Company’s operating results and financial position.
Cash and Cash Equivalents | Cash and Cash Equivalents Temporary investments with original maturities of ninety days or less are included in cash and cash equivalents.
Inventories | Inventories Inventories, consisting primarily of refrigerant products available for sale, are stated at the lower of cost, on a first-in first-out basis, or net realizable value. Where the market price of inventory is less than the related cost, the Company may be required to write down its inventory through a lower of cost or net realizable value adjustment, the impact of which would be reflected in cost of sales on the Consolidated Statements of Operations. Any such adjustment would be based on management’s judgment regarding future demand and market conditions and analysis of historical experience.
Property, Plant and Equipment | Property, Plant and Equipment Property, plant and equipment are stated at cost, including internally manufactured equipment. The cost to complete equipment that is under construction is not considered to be material to the Company’s financial position. Provision for depreciation is recorded (for financial reporting purposes) using the straight-line method over the useful lives of the respective assets. Leasehold improvements are amortized on a straight-line basis over the shorter of economic life or terms of the respective leases. Costs of maintenance and repairs are charged to expense when incurred. Due to the specialized nature of the Company’s business, it is possible that the Company’s estimates of equipment useful life periods may change in the future.
Goodwill | Goodwill The Company has made acquisitions that included a significant amount of goodwill and other intangible assets. The Company applies the purchase method of accounting for acquisitions, which among other things, requires the recognition of goodwill (which represents the excess of the purchase price of the acquisition over the fair value of the net assets acquired and identified intangible assets). The Company tests its goodwill for impairment annually on a qualitative or quantitative basis (on the first day of the fourth quarter) and between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of an asset below its carrying value. Goodwill is tested for impairment at the reporting unit level. When performing the annual impairment test, the Company has the option of first performing a qualitative assessment, which requires management to make assumptions affecting a reporting unit, to determine the existence of events and circumstances that would lead to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If such a conclusion is reached, the Company is then required to perform a quantitative impairment assessment of goodwill. The Company has one reporting unit at March 31, 2024. Other intangible assets that meet certain criteria are amortized over their estimated useful lives. An impairment charge is recorded based on the excess of a reporting unit’s carrying amount over its fair value. An impairment charge would be recognized when the carrying amount exceeds the estimated fair value of a reporting unit. These impairment evaluations use many assumptions and estimates in determining an impairment loss, including certain assumptions and estimates related to future earnings. If the Company does not achieve its earnings objectives, the assumptions and estimates underlying these impairment evaluations could be adversely affected, which could result in an asset impairment charge that would negatively impact operating results. During the fourth quarter of 2023, the Company completed its annual impairment test as of October 1 and determined in its qualitative assessment it is more likely than not that the fair value of the reporting unit is greater than its carrying amount, resulting in no goodwill impairment. There can be no assurances that future sustained declines in macroeconomic or business conditions affecting the Company’s industry will not occur, which could result in goodwill impairment charges in future periods. There were no goodwill impairment losses recognized in 2023 or the quarter ended March 31, 2024.
Leases | Leases The Company determines if an arrangement contains a lease at inception. An arrangement contains a lease if it implicitly or explicitly identifies an asset to use and conveys the right to control the use of the identified asset in exchange for consideration. As a lessee, the Company includes operating leases in operating lease right-of-use (“ROU”) assets, operating lease liabilities, and non-current operating lease liabilities in its consolidated balance sheets. ​ Finance leases are included in property and equipment in the consolidated balance sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized upon commencement of the lease based on the present value of the lease payments over the lease term. As most of the Company’s leases do not provide an implicit interest rate, the Company generally uses its incremental borrowing rate based on the estimated rate of interest for fully collateralized and fully amortizing borrowings over a similar term of the lease payments and commencement date to determine the present value of lease payments. When readily determinable, the Company uses the implicit rate. The Company’s lease terms include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for lease payments is recognized on a straight-line basis over the lease term. Expenses associated with operating leases and finance leases are included in selling, general and administrative expense within the consolidated statement of income.
Cylinder Deposit Liability | Cylinder Deposit Liability The cylinder deposit liability, which is included in accrued expenses and other current liabilities on the Company’s Balance Sheet, represents the amount due to customers for the return of refillable cylinders. The Company charges its customers cylinder deposits upon the shipment of refrigerant gases that are contained in refillable cylinders. The amount charged to the customer by the Company approximates the cost of a new cylinder of the same size. Upon return of a cylinder, this liability is reduced. The cylinder deposit liability balance was $17.8 million and $17.2 million at March 31, 2024 and December 31, 2023, respectively.
Revenues and Cost of Sales | Revenues and Cost of Sales The Company’s products and services are primarily used in commercial air conditioning, industrial processing and refrigeration systems. Most of the Company’s revenues are realized from the sale of refrigerant and industrial gases and related products. The Company also generates revenue from refrigerant management services performed at a customer’s site and in-house. The Company conducts its business primarily within the US. The Company applies the FASB’s guidance on revenue recognition, which requires the Company to recognize revenue in an amount that reflects the consideration to which the Company expects to be entitled in exchange for goods or services transferred to its customers. In most instances, the Company’s contract with a customer is the customer’s purchase order and the sales price to the customer is fixed. For certain customers, the Company may also enter into a sales agreement outlining a framework of terms and conditions applicable to future purchase orders received from that customer. Because the Company’s contracts with customers are typically for a single customer purchase order, the duration of the contract is usually less than one year. The Company’s performance obligations related to product sales are satisfied at a point in time, which may occur upon shipment of the product or receipt by the customer, depending on the terms of the arrangement. The Company’s performance obligations related to reclamation and RefrigerantSide® services are generally satisfied at a point in time when the service is performed. Accordingly, revenues are recorded upon the shipment of the product, or in certain instances upon receipt by the customer, or the completion of the service. In July 2016 the Company was awarded, as prime contractor, a five-year contract, including a five-year renewal option, which has been exercised through July 2026, by the United States Defense Logistics Agency (“DLA”) for the management, supply, and sale of refrigerants, compressed gases, cylinders, and related services. Due to the contract containing multiple performance obligations, the Company assessed the arrangement in accordance with ASC 606-10-25-14. The Company determined that the sale of refrigerants and the management services provided under the contract each have stand-alone value. Accordingly, the performance obligation related to the sale of refrigerants is satisfied at a point in time, mainly when the customer receives and obtains control of the product. The performance obligation related to management service revenue is satisfied over time and revenue is recognized on a straight-line basis over the term of the arrangement as the management services are provided. For the period ended March 31, 2024 and 2023 management services revenue were $0.6 million respectively. Cost of sales is recorded based on the cost of products shipped or services performed and related direct operating costs of the Company’s facilities. In general, the Company performs shipping and handling services for its customers in connection with the delivery of refrigerant and other products. The Company elected to implement ASC 606-10-25-18B, whereby the Company accounts for such shipping and handling as activities to fulfill the promise to transfer the good. To the extent that the Company charges its customers shipping fees, such amounts are included as a component of revenue and the corresponding costs are included as a component of cost of sales. The Company's revenues are derived from Product and related sales and RefrigerantSide (R) Services revenues. The revenues for each of these lines are as follows: ​
​ | ​ | ​ | ​ | ​ | ​ | ​
Period Ended March 31, |  | 2024 |  | 2023
(in thousands) |  | ​ |  |  | ​ |
Product and related sales | ​ | $ | 63,811 | ​ | $ | 75,983
RefrigerantSide ® Services | ​ |  | 1,439 | ​ |  | 1,216
Total | ​ | $ | 65,250 | ​ | $ | 77,199
​
Income Taxes | Income Taxes The Company is taxed at statutory corporate income tax rates after adjusting income reported for financial statement purposes for certain items. Current income tax expense reflects the tax results of revenues and expenses currently taxable or deductible. The Company utilizes the asset and liability method of accounting for deferred income taxes, which provides for the recognition of deferred tax assets or liabilities, based on enacted tax rates and laws, for the differences between the financial and income tax reporting bases of assets and liabilities. The tax benefit associated with the Company’s net operating loss carry forwards (“NOLs”) is recognized to the extent that the Company expects to realize future taxable income. As of March 31, 2024, the Company had no federal NOLs, as the Company utilized all of its remaining federal NOLs during the year ended December 31, 2022. As of March 31, 2024, the Company had state tax NOLs of approximately $1.2 million, expiring in various years. The Company reviews the likelihood that it will realize the benefit of its deferred tax assets on a quarterly basis. The Company evaluates uncertain tax positions, if any, by determining if it is more likely than not to be sustained upon examination by the taxing authorities. As of March 31, 2024 and December 31, 2023, the Company believes it had no uncertain tax positions.
Income per Common and Equivalent Shares | Income per Common and Equivalent Shares If dilutive, common equivalent shares (common shares assuming exercise of options) utilizing the treasury stock method are considered in the presentation of diluted income per share. The reconciliation of shares used to determine net income per share is as follows (dollars in thousands, unaudited): ​
​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | Three Month Period
​ | ​ | Ended March 31,
​ |  | 2024 |  | 2023
Net income | ​ | $ | 9,562 | ​ | $ | 15,531
​ | ​ | ​ | ​ | ​ | ​ | ​
Weighted average number of shares – basic | ​ |  | 45,509,423 | ​ | ​ | 45,298,514
Shares underlying options | ​ | ​ | 1,959,097 | ​ | ​ | 2,012,513
Weighted average number of shares outstanding – diluted | ​ | ​ | 47,468,520 | ​ | ​ | 47,311,027
​ During the three month periods ended March 31, 2024 and 2023, certain options aggregating 52,519 and 502,568 shares, respectively, have been excluded from the calculation of diluted shares, due to the fact that their effect would be anti-dilutive.
Estimates and Risks | Estimates and Risks The preparation of financial statements in conformity with generally accepted accounting principles in the United States requires the use of estimates and assumptions that affect the amounts reported in these financial statements and footnotes. The Company considers these accounting estimates to be critical in the preparation of the accompanying consolidated financial statements. The Company uses information available at the time the estimates are made. However, these estimates could change materially if different information or assumptions were used. Additionally, these estimates may not ultimately reflect the actual amounts of the final transactions that occur. The Company utilizes both internal and external sources to evaluate potential current and future liabilities for various commitments and contingencies. In the event that the assumptions or conditions change in the future, the estimates could differ from the original estimates. Several of the Company’s accounting policies involve significant judgments, uncertainties, and estimates. The Company bases its estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. To the extent that actual results differ from management’s judgments and estimates, there could be a material adverse effect on the Company. On a continuous basis, the Company evaluates its estimates, including, but not limited to, those estimates related to its allowance for credit losses, inventory reserves, goodwill and commitments and contingencies. With respect to trade accounts receivable, the Company estimates the necessary allowance for credit losses based on both historical and anticipated trends of payment history and the ability of the customer to fulfill its obligations. For inventory, the Company evaluates both current and anticipated sales prices of its products to determine if a write down of inventory to net realizable value is necessary. The Company participates in an industry that is highly regulated, and changes in the regulations affecting its business could affect its operating results. Currently the Company purchases virgin hydrofluorocarbon (“HFC”) and hydrofluroolefin (“HFO”) refrigerants and reclaimable, primarily hydrochlorofluorocarbons (“HCFC”), HFC and chlorofluorocarbon (“CFC”), refrigerants from suppliers and its customers. To the extent that the Company is unable to source sufficient quantities of refrigerants or is unable to obtain refrigerants on commercially reasonable terms or experiences a decline in demand and/or price for refrigerants sold by the Company, the Company could realize reductions in revenue from refrigerant sales, which could have a material adverse effect on its operating results and its financial position. The process of sourcing refrigerants includes various procurement costs, such as freight, processing, insurance, and other costs, relating to the delivery of refrigerants. As a result of the recently noted global supply chain issues, the Company determined it could be exposed to incremental costs related to these refrigerant purchases. These costs represent the Company’s initial estimate that are possibly subject to finalization in future periods and are recorded in accrued expenses and other current liabilities on the consolidated balance sheet as of March 31, 2024. The Company is subject to various legal proceedings. The Company assesses the merit and potential liability associated with each of these proceedings. In addition, the Company estimates potential liability, if any, related to these matters. To the extent that these estimates are not accurate, or circumstances change in the future, the Company could realize liabilities, which could have a material adverse effect on its operating results and its financial position.
Impairment of Long-lived Assets | Impairment of Long-lived Assets The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of the assets to the future net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. Assets to be disposed of are reported at the lower of the carrying amount or fair value less the cost to sell.
Capitalized Software Development Costs | Capitalized Software Development Costs Capitalized internal - use software costs consist of costs to purchase and develop software. For software to be used solely to meet internal needs and for cloud - based applications used to deliver services, the Company capitalizes costs incurred during the application development stage and includes such costs within property and equipment, net within the consolidated balance sheets.
Recent Accounting Pronouncements | Recent Accounting Pronouncements In June 2016, the FASB issued ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments, which revises guidance for the accounting for credit losses on financial instruments within its scope, and in November 2018, issued ASU No. 2018-19 and in April 2019, issued ASU No. 2019-04 and in May 2019, issued ASU No. 2019-05, and in November 2019, issued ASU No. 2019-11, which each amended the standard. The new standard introduces an approach, based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, net investments in leases and off-balance-sheet credit exposures. This ASU is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, with early adoption permitted. Entities are required to apply the standard’s provisions as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The Company adopted ASU No. 2016-13 on January 1, 2023. The adoption of ASU No. 2016-13 did not have a material impact on its results of operations or financial position. In August 2020, the FASB issued ASU 2020-06, “Debt-Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging-Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity”, which is intended to simplify the accounting for convertible instruments by removing certain separation models in Subtopic 470-20, Debt-Debt with Conversion and Other Options, for convertible instruments. The pronouncement is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2022, with early adoption permitted. The Company adopted ASU 2020-06 on January 1, 2023. The adoption of ASU 2020-06 did not have a material impact on its results of operations or financial position. ​ In December 2023, the FASB issued ASU 2023 - 09, "Income Taxes (Topic 740): Improvements to Income Tax Disclosures," which requires public business entities to disclose additional information in specified categories with respect to the reconciliation of the effective tax rate to the statutory rate for federal, state, and foreign income taxes. It also requires greater detail about individual reconciling items in the rate reconciliation to the extent the impact of those items exceeds a specified threshold. In addition to new disclosures associated with the rate reconciliation, the ASU requires information pertaining to taxes paid (net of refunds received) to be disaggregated for federal, state, and foreign taxes and further disaggregated for specific jurisdictions to the extent the related amounts exceed a quantitative threshold. The ASU also describes items that need to be disaggregated based on their nature, which is determined by reference to the item's fundamental or essential characteristics, such as the transaction or event that triggered the establishment of the reconciling item and the activity with which the reconciling item is associated. The ASU eliminates the historic requirement that entities disclose information concerning unrecognized tax benefits having a reasonable possibility of significantly increasing or decreasing in the 12 months following the reporting date. This ASU is effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. This ASU should be applied on a prospective basis; however, retrospective application is permitted. The Company is currently evaluating the impact that ASU 2023 - 09 will have on its consolidated financial statements. In November 2023, the FASB issued ASU 2023 - 07, "Segment Reporting (Topic 280): Improvements to Reportable Segments," which aims to improve financial reporting by requiring disclosure of incremental segment information on an annual and interim basis for all public entities to enable investors to develop more decision - useful financial analyses. Currently, Topic 280 requires that a public entity disclose certain information about its reportable segments. For example, a public entity is required to report a measure of segment profit or loss that the CODM uses to assess segment performance and make decisions about allocating resources. Topic 280 also requires other specified segment items and amounts, such as depreciation, amortization, and depletion expense, to be disclosed under certain circumstances. The amendments in this ASU do not change or remove those disclosure requirements and do not change how a public entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company does not expect that the requirements of ASU 2023 - 07 will have a material impact on its consolidated financial statements.
