Performance Analysis
Perma-Fix delivered a pivotal Q4, with treatment segment revenue and backlog both surging as Hanford-related waste streams and international projects ramped. Treatment revenue grew 29% year-over-year, driven by higher volumes and improved plant throughput, though offset by increased labor and maintenance costs. The treatment backlog rose 51% to $11.9 million, providing a rare degree of forward visibility for a project-driven business. International revenues also saw a sharp 163% jump, reflecting traction in Canada and Europe.
However, services segment revenue declined due to project timing, delayed mobilizations, and government procurement cycles, with gross profit flat as cost reductions offset lower activity. SG&A expenses rose on higher payroll, marketing, and legal costs, while net loss widened due to a remediation reserve adjustment. Cash usage was significant, reflecting both working capital swings and heavy investment in capacity and technology. Notably, Q1 2026 is expected to be soft, with a projected negative EBITDA exceeding $4 million, before a Q2 rebound as Hanford and PFAS volumes accelerate.
- Treatment Segment Strength: Higher waste volumes, improved mix, and expanded capacity drove double-digit growth and backlog gains.
- Services Segment Drag: Project delays and government shutdowns weighed on revenue, though backlog and pipeline are improving.
- Cash Flow Dynamics: Elevated CapEx and working capital outflows reflect pre-ramp investment, with Q2 expected to mark a positive inflection.
Overall, the business is pivoting from investment mode to execution, with Hanford and PFAS as the central growth levers for 2026 and beyond.
Executive Commentary
"One of the most significant milestones in the year was the renewal of the permit for our Permafix Northwest facility. This permit significantly expands our permitted processing capacity to approximately 1.2 million gallons of liquid mixed waste annually, effectively tripling our liquid processing capacity, and also authorizes treatment of up to 175,000 tons of waste through macroencapsulation annually."
Mark Duff, President and CEO
"Our net loss for the quarter was $5.7 million compared to last year's net loss of $3.5 million... For the year ended December 2025, net loss was 13.8 million compared to a net loss of 20 in the prior year. Again, our net loss for 2025 included the 2.7 million recorded in a remediation reserve for our discontinued operations as previously discussed."

Strategic Positioning
1. Hanford Cleanup Mission as Core Growth Engine
The Hanford Direct Feed Low Activity Waste (DFLAW) program, a multi-decade Department of Energy (DOE) remediation project, is emerging as Perma-Fix’s anchor customer. The company’s Northwest facility now boasts tripled liquid processing capacity and is positioned to capture both immediate and long-term waste streams—ranging from effluent blowdown to large-scale grouting initiatives potentially spanning 200 million gallons through 2040. DOE’s evolving waste handling strategy, including a shift toward commercial grouting, directly aligns with Perma-Fix’s capabilities and geographic advantage.
2. PFAS Destruction Platform Scaling Up
PFAS, or per- and polyfluoroalkyl substances, are persistent environmental contaminants. Perma-Fix’s Gen 2.0 PFAS destruction system, with a 3,000-gallon-per-day capacity, is set to triple throughput and lower costs versus incineration. The company is targeting 60–70% incremental margins on higher volume PFAS contracts, with pricing power supported by regulatory tailwinds and customer demand for permanent destruction. Field deployments at airports and partnerships for AFFF (firefighting foam) removal are expanding the commercial funnel.
3. International and Diversified Waste Streams
International revenue rose sharply in 2025, with new Canadian, European, and Mexican projects supplementing U.S. government work. While 2026 international volumes are expected to be down 25–30% versus 2025, the pipeline remains robust, and the company is positioned for a resurgence in 2027 as large remediation projects enter execution.
4. Capacity, Permitting, and Operational Readiness
The renewal of the Northwest permit unlocks flexibility for rapid capacity expansion—up to a proposed 4.2 million gallons of liquid waste annually. Investments in automation, plant upgrades, and workforce expansion are designed to ensure the facility can absorb the Hanford ramp and future DOE awards. The company is also pursuing permit modifications to further scale operations as opportunities materialize.
5. Project-Based Services: Cyclical but Improving
Services revenue remains lumpy, tied to project mobilizations and government procurement cycles. However, a $30 million new backlog and $40 million in bids submitted in Q1 2026 signal an improving outlook. The segment’s return to growth will support higher facility utilization and cross-sell opportunities with treatment operations.
Key Considerations
This quarter marks a strategic turning point, with Perma-Fix moving from capacity-building to execution. The company is now positioned to leverage its expanded infrastructure, regulatory wins, and technology differentiation against a backdrop of rising demand from both government and commercial customers.
Key Considerations:
- Hanford Waste Stream Visibility: DOE’s DFLAW and grouting initiatives create long-term, recurring treatment demand for Perma-Fix’s Northwest facility.
- PFAS Commercialization: Gen 2.0 system offers cost leadership and margin expansion, with regulatory momentum supporting adoption.
- Project Timing Volatility: Revenue recognition and project mobilizations drive quarterly swings, but backlog and pipeline trends are positive.
- Capacity and Permitting: Permit renewal and planned modifications enable rapid scale-up, removing regulatory bottlenecks for growth.
- Cash and CapEx Discipline: Continued investment is required, but management asserts working capital is sufficient for near-term needs.
Risks
Execution risk remains high, as the timing and volume of Hanford and DOE waste streams are dependent on government schedules and regulatory approvals. Project-based services revenue is inherently cyclical, and international volumes may fluctuate. Elevated CapEx and negative near-term EBITDA could strain liquidity if the Q2 ramp is delayed. Regulatory or permitting setbacks, especially for PFAS or Hanford, would materially impact growth plans.
Forward Outlook
For Q2 2026, Perma-Fix expects:
- Significant revenue and margin improvement driven by Hanford waste receipts and PFAS system ramp.
- Return to profitability as facility utilization increases and backlog converts to revenue.
For full-year 2026, management did not provide formal guidance but highlighted:
- Progressive ramp in Hanford-related activity, with DFLAW and grouting programs contributing increasing volumes through the year.
- PFAS system commercialization and international project execution as incremental growth drivers.
Management emphasized that Q1 will be soft due to project timing, but Q2 and Q3 are expected to show sustainable improvement as new contracts and waste streams come online.
Takeaways
Perma-Fix is at a strategic inflection, with Hanford and PFAS platforms set to drive multi-year growth.
- Backlog and Capacity Expansion: The 51% treatment backlog increase and permit-driven capacity unlocks support a step-change in revenue visibility and execution potential.
- PFAS Technology as Margin Lever: Commercial-scale PFAS destruction offers high incremental margins and regulatory-driven demand, positioning Perma-Fix as a cost leader.
