Hudson Technologies (HDSN) Q3 2026 earnings review
Hudson Technologies sales volume drops, but cash rebounds by $10M
Hudson Technologies, which reclaims and sells cooling gases for air conditioners, saw both its prices and sales volumes fall while overhead costs kept climbing. Revenue dropped 20% to $59 million as selling prices fell 17% against last year's supply-shortage peak, and profit fell to $2 million. Chief executive Ken Gaglione kept the full-year gross margin outlook in the low-to-mid-twenty percent range.
| Revenue | $59.4M -19.7% from a year ago |
|---|---|
| Sales volume | -9% +12% last quarter |
| Gross margin | 25% 32% a year ago |
| Full-year gross margin outlook | Unchanged low-to-mid-twenty percent |
⚖️ Verdict: 🔴 Bearish
The story got worse because sales volume shrank by 9% after two quarters of double-digit growth, removing the one buffer that had protected revenue from low refrigerant prices. At the same time, overhead spending rose 22% to pay for software and consultants. One bright spot: seasonal customer collections brought in $10 million of cash, lifting the cash balance to $35 million with no debt.
The question now is whether the third-quarter volume drop was a one-off pause after heavy early-season buying or the start of a longer slump caused by full customer warehouses. Either the extra overhead spending starts bringing in new service revenue in 2027, or higher staff and consulting bills permanently shrink profit margins. Fourth-quarter reclamation volume and next year's expense budget will tell.
🐂 Bull Case
Working Capital Release Lifted Cash by $10 Million
Hudson Technologies collects cash at the end of the summer cooling season as customers pay for earlier purchases. In the first half of 2026, the refrigerant supplier burned $6.0 million in operating cash, which raised concerns because its cash balance had fallen from $89.7 million a year earlier to $25.6 million in June.
Cash rose by $9.7 million this quarter to $35.3 million, and the balance sheet remains debt-free. By our math, the business generated $10.2 million in operating cash flow and $9.7 million in free cash flow during the third quarter as accounts receivable fell from $43.3 million in June to $29.8 million. Management still bought back no shares for a second straight quarter.
What to watch: the terms of the credit facility renewal due before March 2, 2027. A renewal that keeps the $40 million borrowing limit would show lenders are comfortable with seasonal cash swings.
Defense Contract and Icorium Deal Back Long-Term Plans
Chief executive Ken Gaglione wants to reduce the company's reliance on refrigerant prices by expanding into services and better purification tools. During the quarter, the US company signed a formal joint development agreement with Icorium for separation technology to "enable the more efficient separation of complex, mixed refrigerants, enhancing our existing distillation technology."
The group also secured its re-awarded contract with the Defense Logistics Agency (DLA), the US military's supply agency, valued at $210 million over five years. While the defense deal removes the risk of losing a major buyer and the Icorium agreement turns an earlier letter of intent into a formal project, neither adds new revenue this year.
What to watch: any disclosure of required capital spending for the Icorium technology in the annual report. A clear budget and timeline would show when the project can start helping gross margins.
🐻 Bear Case
Sales Volume Turned Negative After Two Strong Quarters
For the first half of the year, rising sales volume made up for weak refrigerant prices, growing 20% in the first quarter and 12% in the second. Gaglione highlighted nine-month volume growth of 9% as proof of customer relationships, but that figure hides a sharp reversal in the third quarter.
- Third-quarter sales volume: down 9% from a year ago
- Third-quarter selling prices: down 17% from a year ago
- Third-quarter revenue: $59.4 million, down 19.7% from a year ago
Hudson said "muted customer demand and adequate refrigerant inventories compressed sales activity" compared to last year's supply shortages. Because distributors already hold enough inventory, the company could not use higher volume to offset the 17% price drop, causing quarterly revenue to fall nearly $15 million.
What to watch: fourth-quarter sales volume against last year's 28% revenue jump. Another volume drop would show that customer stockpiles are still too high heading into 2027.
Overhead Spending Keeps Rising While Revenue Falls
Management has increased overhead spending all year to pay for new staff, consultants, and software. Selling, general and administrative expenses — the cost of staff, consultants, and office overhead — rose 21.7% from a year ago to $10.8 million, climbing from 12.0% of revenue to 18.2%, a jump of 6.2 percentage points.
The company said the extra money went toward "continued investment in optimizing the ERP system launched earlier this year, as well as additional staffing and consulting resources supporting the Company’s longer-term value-creation initiatives." Because gross profit fell by $8.9 million at the same time, operating margin shrank by 13.4 percentage points to 5.5%, and net income fell 83.5% to $2.0 million.
What to watch: fourth-quarter overhead expenses against the second-half plan of $22.8 million to $27.3 million. By our math, that leaves $12.0 million to $16.5 million for the fourth quarter, and landing near the top would likely push the quarter into an operating loss.
Cheaper Refrigerant Prices Cut Into Gross Margin
"Third-quarter revenue reflected continued softness in HFC market pricing and lower sales volume," Gaglione said. Hydrofluorocarbons (HFCs) are the cooling gases Hudson reclaims and sells, and their market prices jumped a year ago during supply chain shortages tied to federal environmental rules.
Lapping that spike pushed selling prices down 17% from a year ago, while higher fuel costs also weighed on operations. As a result, the cost of making and sourcing products rose by 7.1 percentage points of revenue to 75.1%, pulling gross margin down from 32.0% a year ago to 24.9%.
What to watch: full-year reclamation volume growth in the fourth-quarter report. A drop below last year's 18% growth rate would show that low market prices are discouraging contractors from returning used gas.
Risks this quarter didn't answer
Several standing concerns about customer concentration, service revenue, and inventory costs got no new detail in the earnings release.
- Service revenue targets: promised in late 2025 for predictive chiller diagnostics and recovery trucks, but still not disclosed.
- Quarterly reclamation volume: only reported once a year in the fourth quarter, leaving the core business trend unreadable today.
- Customer concentration: one non-government buyer held 20% of receivables in June; the quarterly filing will show if that balance was collected.
💲 Other KPIs
Inventories rose 35.0% from $97.4 million a year ago and ticked up from $128.1 million in June. By our math, the third quarter included a $2.5 million non-cash inventory cost charge after $5.0 million of inventory cost relief in the first half, showing that stockpiles remain heavy heading into the slow winter season.
Money owed by customers fell from the seasonal peak of $43.3 million in June, which helped bring in cash during the quarter. Still, receivables sit 17.4% higher than a year ago even though third-quarter revenue dropped 19.7%, meaning customers are taking longer to pay than they did last year.
The diluted share count fell 6.7% from 45.2 million a year ago because of stock buybacks completed in late 2025 and early 2026, alongside executive option settlements. It barely moved from 42.2 million in the second quarter because Hudson paused share repurchases for a second straight quarter.
🔮 Guidance
Unchanged. The company kept its full-year gross margin target in the "low-to-mid-twenty percent range, consistent with its previously announced target" after cutting it from mid-twenty percent last quarter. With gross margin at 23.9% through nine months, the target is achievable. By our math, the middle of the range (22.5%) leaves about 16.2% gross margin for the seasonally slow fourth quarter if revenue matches last year.
❓ Key Questions
Why did third-quarter sales volume drop 9%?
Sales volume grew 20% in the first quarter and 12% in the second before falling 9% in the third. Investors need to know whether higher customer inventories will also hold back orders in the first half of 2027.
How much capital will the Icorium project require?
Hudson signed a formal joint development agreement with Icorium this quarter to separate mixed refrigerants. Management has not yet said how much money it will spend to build the equipment or when it will be ready for commercial use.
When will overhead spending stop growing?
Selling, general and administrative expenses rose 21.7% in the third quarter to $10.8 million for software, staff, and consultants. With the new software system live since February, investors need to know when consulting bills will roll off.
How did inventory cost adjustments affect third-quarter margin?
The nine-month cash flow statement shows a $2.5 million inventory valuation benefit, down from $5.0 million at mid-year. That implies a $2.5 million non-cash charge in the third quarter that management did not explain in the release.
