Computed values are grepcent-computed from the verified facts above and may differ from ratios the company itself reports. Free cash flow = operating cash flow − capital expenditures. Net margin = net income ÷ revenue. Operating margin = operating income ÷ revenue. Revenue YoY = FY2025 revenue ÷ FY2024 revenue − 1 (consecutive fiscal years only). ROE = net income ÷ period-end stockholders' equity.

Item 2 - Management’s Discussion and Analysis of Financial Condition and Results of Operations

Certain statements, contained in this section and elsewhere in this Form 10-Q, constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements involve a number of known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. Such factors include, but are not limited to, changes in the laws and regulations affecting the industry, changes in the demand and price for refrigerants (including unfavorable market conditions adversely affecting the demand for, and the price of refrigerants), the Company’s ability to source refrigerants, regulatory and economic factors, seasonality, competition, litigation, the nature of supplier or customer arrangements that become available to the Company in the future, adverse weather conditions, possible technological obsolescence of existing products and services, possible reduction in the carrying value of long-lived assets, estimates of the useful life of its assets, potential environmental liability, customer concentration, the ability to obtain financing, the ability to meet financial covenants under our financing facility, any delays or interruptions in bringing products and services to market, the timely availability of any requisite permits and authorizations from governmental entities and third parties as well as factors relating to doing business outside the United States, including changes in the laws, regulations, policies, and political, financial and economic conditions, including inflation, interest and currency exchange rates, of countries in which the Company may seek to conduct business, the Company’s ability to successfully integrate any assets it acquires from third parties into its operations, and other risks detailed in the Company’s Form 10-K for the year ended December 31, 2025, and in the Company’s other subsequent filings with the Securities and Exchange Commission (“SEC”). The words “believe”, “expect”, “anticipate”, “may”, “plan”, “should” and similar expressions identify forward-looking statements. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date the statement was made.

Critical Accounting Estimates

The Company’s discussion and analysis of its financial condition and results of operations are based upon its consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and related disclosure of contingent assets and liabilities. 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 inventory reserves, goodwill and intangible assets.

Inventory

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. Net realizable value represents the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion and disposal. The determination if a write-down to net realizable value is necessary is primarily affected by the market prices for the refrigerant gases we sell. Commodity prices generally are affected by a wide range of factors beyond our control, including weather, seasonality, the availability and adequacy of supply, government regulation and policies and general political and economic conditions. At any time, our inventory levels may be substantial and fluctuate, which will materially impact our estimates of net realizable value.

Overview

The Company is a leading provider of sustainable refrigerant products and services to the Heating Ventilation Air Conditioning and Refrigeration (“HVACR”) industry. For nearly three decades, we have demonstrated our commitment to our customers and the environment by becoming one of the United States’ largest refrigerant reclaimers through multimillion dollar investments in the plants and advanced separation technology required to recover a wide variety of refrigerants and restoring them to Air-Conditioning, Heating, and Refrigeration Institute (“AHRI”) standard for reuse as certified EMERALD Refrigerants™.

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, which include system decontamination to remove moisture, oils and other contaminants.

Sales of refrigerants continue to represent a significant majority of the Company’s revenues.

The Company also sells industrial gases to a variety of industry customers, predominantly to users in, or involved with, the US Military. In July 2016, the Company was awarded, as prime contractor, a five-year fixed price contract, including a five-year renewal option which has been exercised, awarded to it by the United States Defense Logistics Agency (“DLA”) for the management and supply of refrigerants, compressed gases, cylinders and related items to US Military commands and installations, Federal civilian agencies and foreign militaries. Primary users include the US Army, Navy, Air Force, Marine Corps and Coast Guard. Our contract with DLA was set to expire in July 2026, but has been extended as described below.

In October 2025, the DLA awarded a new five-year contract with a five-year renewal option to the Company (the “2025 DLA Contract”). Following issuance of the new contract, a competitor filed a bid protest at the U.S. Court of Federal Claims, challenging the DLA’s evaluation of proposals and the contract award to the Company. In response, the DLA rescinded the 2025 DLA Contract award and commenced a re-bid process. On May 27, 2026, the Company received a bridge modification from the DLA extending the expiration date of the existing DLA contract to November 29, 2026, with two additional three-month options to February 28, 2027 and May 29, 2027. The contract extension served as bridge under the current agreement while the DLA completed the rebidding process. On August 4, 2026, following the completion of the re-bidding process, the Company was re-awarded the previously disputed and rescinded agreement with the DLA. The initial term of the new DLA contract runs through August 4, 2031 with the DLA holding a five-year option to extend the term through July 31, 2036.

2025 Acquisition

On December 16, 2025, the Company’s subsidiary Hudson Technologies Company completed the acquisition of substantially all the business assets of Denver Refrigerants Inc. (d/b/a Refrigerants Inc.). The consideration for the Refrigerants Inc. acquisition was approximately $2.2 million in cash, paid at the closing, and provides for a further contingent payment of up to $2.0 million payable, to the extent earned, approximately 17 and 29 months from the closing date.

Refrigerants Inc. is a leading refrigerant distributor and distributes, reclaims and packages refrigerant gases for a variety of end uses. Potential benefits of the Refrigerants Inc. acquisition include (i) providing a broader customer network which will provide the Company with increased access to refrigerant for reclamation and strengthen the Company’s refrigerant distribution capabilities; (ii) adding incremental access to recovered pounds of refrigerants for sale for future periods to support the growth in reclamation; and (iii) enhancing the Company’s geographic footprint in the United States.

AIM Act

The United States Environmental Protection Agency (“EPA”) issued several final rules establishing the framework to allocate allowances for production and consumption of newly manufactured hydrofluorocarbon refrigerants (“HFCs”) and has provided allowances through 2029. The EPA is responsible for the administration of the HFC phase down enacted by Congress under the American Innovation and Manufacturing Act (the “AIM Act”). There are no restrictions placed on the reclamation of HFC refrigerants.

The AIM Act directs the EPA to address the reduction in virgin HFCs and provides authority to do so in three respects:

[[GREPCENT_TABLE]]
[["","1)","phase down the production and consumption of listed HFCs,"]]
[[/GREPCENT_TABLE]]

[[GREPCENT_TABLE]]
[["","2)","facilitate the transition to next-generation technologies, and"]]
[[/GREPCENT_TABLE]]

[[GREPCENT_TABLE]]
[["","3)","manage these HFCs and their substitutes including reclamation of refrigerants."]]
[[/GREPCENT_TABLE]]

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 2029. Hudson received allocation allowances for calendar years 2024 and 2025 equal to approximately 1% of the total HFC consumption allowances, with allowances for future periods to be determined at a later date. In addition, the EPA has finalized the Technology Transition (“TT”) Rule in 2023, but the Trump administration decided to reconsider the TT rule by issuing a proposed new TT rule in 2025 with a final TT rule expected in third quarter of 2026. Additionally, the EPA issued a final Refrigerant Management Rule implementing Subsection (h) of the AIM Act in 2024.

Reclamation is critical to maintaining necessary HFC supply levels for the installed base of operating systems to ensure an orderly phasedown so that systems owners are able to recognize the full economic value of their systems through end of life. Reclamation is not subject to the allowance system or restricted from use.

On September 20, 2024, the EPA announced the latest actions to phase down HFCs under the AIM Act:

Final Refrigerant Management Rule – The rule requires better management and reuse of existing HFCs, including by reducing wasteful leaks from equipment and supporting HFC recycling and reclamation. The rule includes requirements for repairing leaky

equipment, use of automatic leak detection systems on large refrigeration systems, mandating the use of reclaimed HFCs for certain applications, recovery of HFCs from cylinders before their disposal, and a container tracking system.

Results of Operations

Three-month period ended June 30, 2026 as compared to the three-month period ended June 30, 2025

Revenues for the three-month period ended June 30, 2026 were $78.3 million, an increase of $5.5 million or 8% from the $72.8 million reported during the comparable 2025 period. The increase was primarily attributable to higher sales volumes which were partially offset by the lower average market prices of refrigerants sold.

Gross profit and gross margin for the three-month period ended June 30, 2026, were $20.7 million and 26% respectively, a decrease of $2.

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 inventory reserves, goodwill and intangible assets.

Inventory

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. Net realizable value represents the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion and disposal. The determination if a write-down to net realizable value is necessary is primarily affected by the market prices for the refrigerant gases we sell. Commodity prices generally are affected by a wide range of factors beyond our control, including weather, seasonality, the availability and adequacy of supply, government regulation and policies and general political and economic conditions. At any time, our inventory levels may be substantial and fluctuate, which will materially impact our estimates of net realizable value.

Overview

The Company is a leading provider of sustainable refrigerant products and services to the Heating Ventilation Air Conditioning and Refrigeration (“HVACR”) industry. For nearly three decades, we have demonstrated our commitment to our customers and the environment by becoming one of the United States’ largest refrigerant reclaimers through multimillion dollar investments in the plants and advanced separation technology required to recover a wide variety of refrigerants and restoring them to Air-Conditioning, Heating, and Refrigeration Institute (“AHRI”) standard for reuse as certified EMERALD Refrigerants™.

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, consisting of system decontamination to remove moisture, oils and other contaminants.

Sales of refrigerants continue to represent a significant majority of the Company’s revenues.

The Company also sells industrial gases to a variety of industry customers, predominantly to users in, or involved with, the US Military. In July 2016, the Company was awarded, as prime contractor, a five-year fixed price contract, including a five-year renewal option which has been exercised, awarded to it by the United States Defense Logistics Agency (“DLA”) for the management and supply of refrigerants, compressed gases, cylinders and related items to US Military commands and installations, Federal civilian agencies and foreign militaries. Primary users include the US Army, Navy, Air Force, Marine Corps and Coast Guard. Our contract with DLA expires in July 2026.

In October 2025, the DLA awarded a new five-year contract with a five-year renewal option to the Company (the “2025 DLA Contract”). Following issuance of the new contract, a competitor filed a bid protest at the U.S. Court of Federal Claims, challenging the DLA’s evaluation of proposals and the contract award to the Company. In response, the DLA is reviewing its evaluation to determine whether corrective action is necessary and has rescinded the 2025 DLA Contract award during this process. While the bid protest and corrective action is pending, the Company will continue providing logistics support under its existing contract which runs through July 2026.

Recent Acquisition

On December 16, 2025, the Company’s subsidiary Hudson Technologies Company completed the acquisition of substantially all the business assets of Denver Refrigerants Inc. (d/b/a Refrigerants Inc.). The consideration for Refrigerants Inc. acquisition was approximately $2.2 million in cash, paid at the closing, and provides for a further contingent payment of up to $2.0 million payable, to the extent earned, approximately 17 and 29 months from the closing date.

Refrigerants Inc. is a leading refrigerant distributor and distributes, reclaims and packages refrigerant gases for a variety of end uses. Potential benefits of the Refrigerants, Inc. Acquisition include (i) providing a broader customer network which will provide the Company with increased access to refrigerant for reclamation and strengthen the Company’s refrigerant distribution capabilities; (ii) adding incremental access to recovered pounds of refrigerants for sale for future periods to support the growth in reclamation; and (iii) enhancing the Company’s geographic footprint in the United States.

Results of Operations

Year ended December 31, 2025 as compared to the year ended December 31, 2024

Revenues for the year ended December 31, 2025 were $246.6 million, an increase of $9.5 million or 4% from the $237.1 million reported during the comparable 2024 period. The increase was primarily attributable to higher sales volumes which was partially offset by lower average selling prices of refrigerant sold during the period.

Gross profit and gross margin for the year ended December 31, 2025, were $62.1 million and 25.2% respectively, a decrease of $3.6 million and 2.5% respectively from the $65.7 million and 27.7% reported during the comparable 2024 period. The decrease of $3.6 million gross profit and the decline in gross margin were primarily due to lower average selling prices for certain refrigerants, and higher freight costs.

Selling, general and administrative (“SG&A”) expenses for the year ended December 31, 2025 were $40.2 million, an increase of $7.2 million from the $33.0 million reported during the comparable 2024 period. The 2025 SG&A expenses included $4.0 million of severance expense. The increase in SG&A also reflected increased personnel costs amongst other higher costs.

Amortization expense for the years ended December 31, 2025 and 2024 was $3.3 million and $3.4 million, respectively.

Net interest income for the year ended December 31, 2025 was 2.5 million, compared to the net interest income of $0.5 million reported during the comparable 2024 period reflecting the Company’s unlevered balance sheet and higher cash position throughout the year.

Other income for the year ended December 31, 2025, was $1.6 million, compared to $2.3 million reported during the same period in 2024. In the third quarter of 2025, the Company recognized $1.6 million in other income from the reversal of earn-out liabilities related to the 2024 acquisition of USA Refrigerants. Other income of $2.3 million for the same period in 2024 was primarily driven by $1.8 million from litigation settlement proceeds and $0.5 million from a lease opt-out associated with the Atlanta facility.

Income tax expense for 2025 was $6.0 million compared to income tax expense of $7.6 million for 2024. Income tax expense for federal and state income tax purposes was determined by applying statutory income tax rates to pre-tax income after adjusting for certain items.

Net income for the year ended December 31, 2025 was $16.7 million, a decrease of $7.7 million from the $24.4 million of net income reported during the comparable 2024 period, primarily due to lower average selling prices for certain refrigerants, and higher freight costs. and higher SG&A costs, as described above.
