Pattern Detected

Recent news shows mixed reactions: buyback authorization drew a strong positive move, while several strategically positive updates (acquisition, CARB pilot) saw negative price reactions.

Recent Company History

Over the past few months, Hudson announced several strategic and corporate developments. In December 2025 it increased its share repurchase authorization, which coincided with a 6.76% gain. The company then secured a role in California’s REFRESH pilot and acquired Refrigerants Inc., though both drew modest negative reactions. In January 2026, an update on a Defense Logistics Agency contract and a February conference-call notice saw minimal moves. Today’s earnings update fits into a period of ongoing strategic expansion, capital returns, and contract-related uncertainty.

Analysis

The stock dropped -10.6% in the session following this news. A negative reaction despite revenue growth would fit a pattern where strategically positive updates, such as the Refrigerants Inc. acquisition and CARB pilot selection, previously saw price declines of 0.54% and 3.72%. Investors have also seen margins narrow to 8.0% in Q4 and full-year net income fall to $16.7 million. The effective $100,000,000 shelf underscores ongoing financing flexibility and potential dilution if tapped.

Key Terms

non-gaap, lower of cost or market, erp system, share repurchase authorization
4 terms
non-gaap financial
"Non-GAAP Adjusted SG&A was $9.9 million compared to $8.0 million in the fourth quarter..."
Non-GAAP refers to financial measures that companies use to show their earnings or performance without including certain expenses or income that are often added back to give a different picture. It matters because it can make a company's results look better or more favorable, but it may also hide important costs, so investors need to look at both GAAP (official rules) and non-GAAP numbers to get a full understanding.
lower of cost or market financial
"The 2025 gross margin included $4.2 million of inventory related costs, including a lower of cost or market adjustment..."
An accounting rule that requires a company to record inventory at the lower of its original purchase cost or its current market value, so unsellable or devalued stock is not overstated on the balance sheet. For investors, it matters because it can reduce reported assets and profits when prices fall or goods become obsolete, offering a more conservative view of a company’s financial health—like marking down items on a store shelf to reflect what they can actually fetch today.
erp system technical
"the Company went live with a new ERP system that is expected to add connectivity..."
An ERP system is integrated software that brings a company’s core operations—such as accounting, inventory, sales, human resources and purchasing—into a single platform so information flows smoothly between departments. Like replacing a stack of separate tools with one central dashboard, it can lower costs, speed decisions, improve reporting and make scaling easier; investors watch ERP projects because they affect profitability, transparency and execution risk during rollout.
share repurchase authorization financial
"our board of directors had approved an increase to the Company’s share repurchase authorization to up to $20 million..."
A share repurchase authorization is a company's official approval to buy back its own shares from the market. This signals that the company believes its stock is a good investment and can help increase the value of remaining shares by reducing how many are available. For investors, it often suggests confidence from the company and can influence the stock’s price.

AI-generated analysis. Not financial advice.

  • 28% growth in fourth quarter revenue to $44.4 million
  • Annual refrigerant sales volume grew by 6%
  • Annual refrigerant reclamation volume increased by 18% for second consecutive year
  • Maintained strong, unlevered balance sheet
  • Completed accretive acquisition of Refrigerants Inc.
  • Board approved $20 million share repurchase authorization for 2026

WOODCLIFF LAKE, N.J., March 04, 2026 (GLOBE NEWSWIRE) -- Hudson Technologies, Inc. (NASDAQ: HDSN) announced results for the fourth quarter and year ended December 31, 2025.

Kenneth Gaglione, President and Chief Executive Officer of Hudson Technologies commented, “Hudson delivered a strong finish to 2025 with fourth quarter results that included revenue growth of 28% and the successful execution of our accretive acquisition of Refrigerants Inc.

“We also achieved a second consecutive year of 18% growth in refrigerant reclamation volume, a key driver of our long-term business strategy, helping to provide our operations with lower cost refrigerant feedstock. Reclamation is an integral part of the refrigerant supply chain, especially with the continuing phase down of HFCs through the AIM Act. Our demonstrated growth in reclaim volume illustrates the success of our efforts to expand the Company’s market presence and promote the adoption of the practice of recovering refrigerants. We have strategically expanded our capabilities and geographic reach related to securing recovered refrigerants, strengthened by our acquisition of USA Refrigerants in 2024 and Refrigerants Inc. in December 2025. We remain committed to our efforts to educate and build awareness among the contractor community around the benefits of recovering used refrigerant, both from a sustainability and economic perspective.

“Our unlevered balance sheet remained strong with a cash position of $39.5 million at December 31, 2025. During the fourth quarter we demonstrated our commitment to the Company’s capital allocation strategy, which is centered around driving organic growth, executing on strategic acquisitions and making opportunistic share repurchases. In the fourth quarter we invested in restocking inventory, acquired Refrigerants Inc. and repurchased $14 million of common stock. The investment in inventory at year end ensures that we are well positioned for the upcoming selling season.

“During the fourth quarter we announced that our board of directors had approved an increase to the Company’s share repurchase authorization to up to $20 million in shares of common stock for each of full year 2025 and full year 2026 as part of our share repurchase program. With the $14 million of stock purchased in the fourth quarter we fully utilized the 2025 authorization.

“We enter 2026 energized by the organic and strategic opportunities in front of us and look forward to expanding Hudson’s longstanding leadership role in lifecycle refrigerant management. The phase out of HFC refrigerants is well underway and we believe our reputation for service excellence, our customer base, proprietary reclamation technology and proven distribution network leave us well positioned to meet the evolving demands of the industry,” Mr. Gaglione concluded.

Three Month Results

For the quarter ended December 31, 2025, Hudson reported:

  • Revenues increased 28% to $44.4 million compared to revenues of $34.6 million in the comparable 2024 period. The increase was primarily related to stronger sales volume.

  • Gross margin of 8.0% compared to 16.7% in the fourth quarter of 2024. The 2025 gross margin included $4.2 million of inventory related costs, including a lower of cost or market adjustment related to the fourth quarter inventory build.

  • Selling, general and administrative expenses of $13.9 million compared to $8.0 million in the fourth quarter of 2024. SG&A in the fourth quarter of 2025 included $4.0 million of executive severance costs. Non-GAAP Adjusted SG&A was $9.9 million compared to $8.0 million in the fourth quarter of 2024 with the variance related to increased headcount. 

  • Operating loss of $11.2 million compared to an operating loss of $3.2 million in the prior year period. The 2025 operating loss includes the $8.2 million in inventory and severance costs noted above. Non-GAAP Adjusted operating loss, which excludes the $4.0 million severance cost was $7.2 million compared to $3.2 million in the 2024 quarter.

  • Net loss of $8.6 million or a loss of $0.20 per basic and diluted share, which includes the after-tax impact of the $8.2 million of costs noted above, compares to a net loss of $2.6 million or $0.06 per basic and diluted share in the prior year period. Non-GAAP Adjusted net loss, which excludes the after-tax impact of the $4.0 million executive severance cost, was $5.4 million or $0.13 per diluted share compared to a non-GAAP Adjusted net loss of $2.6 million or $0.06 per diluted share in the prior year period.

Full Year 2025 Results

For the full year ended December 31, 2025, Hudson reported:

  • Revenues increased 4% to $246.6 million compared to revenues of $237.1 million for 2024. The increase in revenues was related to a 6% growth in sales volume partially offset by a decrease in refrigerant pricing.

  • Gross margin of 25.2% compared to gross margin of 27.7% for full year 2024, which included the decrease in refrigerant pricing coupled with higher freight costs.
  • Selling, general and administrative expenses were $40.2 million compared to $33.0 million in 2024. Non-GAAP Adjusted SG&A was $36.2 million compared to $32.6 million, with the variance to 2024 primarily related to the mid-year 2024 increase to the sales staff.

  • Operating income was $18.6 million compared to $29.3 million in 2024. Non-GAAP Adjusted operating income was $22.6 million compared to $29.7 million in 2024.

  • Net income of $16.7 million or $0.38 per basic and $0.37 per diluted share compared to net income of $24.4 million or $0.54 per basic and $0.52 per diluted share. Non-GAAP Adjusted net income was $19.7 million or $0.44 per diluted share compared to $24.7 million or $0.52 per diluted share.

    (See tabular reconciliation of GAAP to non-GAAP adjusted financial measures in the back of this release)

At December 31, 2025 the Company reported $39.5 million in cash and cash equivalents.

Subsequent to the end of the fourth quarter, on February 1, 2026 the Company went live with a new ERP system that is expected to add connectivity to its operations and provide a more efficient platform for reliably serving its customers. As is common with new ERP implementations, the Company has experienced some startup inefficiencies that it expects will negatively impact first quarter 2026 revenues. Despite this headwind, Hudson anticipates that it will achieve a low-to-mid single digit revenue growth percentage in first quarter 2026 as compared to first quarter 2025. The Company does not expect inefficiencies from the ERP launch to persist into the second quarter of 2026.

About Non-GAAP Financial Measures

This release is intended to supplement, rather than to supersede, the Company's consolidated financial statements, which are prepared and presented in accordance with U.S. generally accepted accounting principles (“GAAP”). In this release the Company has included financial measures that are derived from the consolidated financial statements but are not presented in accordance with GAAP. The Company uses non-GAAP financial measures, including adjusted SG&A expenses, adjusted operating income (loss) and margin, adjusted net income (loss) and adjusted diluted earnings (loss) per share (collectively, the “non-GAAP financial measures”). The Company computes these non-GAAP financial measures by adjusting the comparable GAAP measure to remove the impact of certain specified charges and gains and the related tax effect of these adjustments. Investors should consider these non-GAAP financial measures in addition to, and not as a substitute for, or superior to, the financial performance measures prepared in accordance with GAAP. The Company uses these non-GAAP financial measures for financial and operational decision making and to evaluate period-to-period comparisons. The Company believes that they provide useful information about operating results, enhance the overall understanding of past financial performance and prospects, and allow for greater transparency with respect to key metrics used by management in its financial and operational decision making. A reconciliation of these non-GAAP financial measures to the most directly comparable financial measure reported in accordance with GAAP is provided at the end of this release.

Reconciliation of Non-GAAP Financial Measures

To supplement the financial measures prepared in accordance with GAAP, the Company uses non-GAAP financial measures, including adjusted selling, general and administrative expenses, adjusted operating income (loss) and margin, adjusted net income (loss) and adjusted diluted earnings (loss) per share. The reconciliations of these non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with GAAP are shown in tables below. These non-GAAP measures are derived from the consolidated financial statements but are not presented in accordance with GAAP. The Company believes these non-GAAP measures provide a meaningful comparison of its results to others in its industry and prior year results. Investors should consider these non-GAAP financial measures in addition to, and not as a substitute for, its financial performance measures prepared in accordance with GAAP. Moreover, these non-GAAP financial measures have limitations in that they do not reflect all the items associated with the operations of the business as determined in accordance with GAAP.
