Perma-Fix (PESI) Q3 2025: Treatment Segment Revenue Surges 45%, Hanford Pathway Secured
Perma-Fix’s third quarter spotlighted a decisive shift in margin structure, propelled by a 45% year-over-year surge in treatment segment revenue and a doubling of gross profit. The company’s Hanford designation cements its role in a multi-decade Department of Energy (DOE) cleanup, while PFAS destruction technology advances with early cost and environmental advantages. Backlog expansion and operational automation signal greater throughput and long-term revenue visibility as Perma-Fix transitions into a new era of recurring, high-value contracts.
Summary
- DOE Hanford Program Locks in Multi-Decade Role: Perma-Fix Northwest is now the designated treatment pathway for Hanford’s DFLAW waste streams.
- Margin Expansion Driven by Treatment Mix: Higher waste volumes and mix optimization doubled gross profit and lifted segment margin to 17.3%.
- PFAS Destruction Achieves Technical Milestone: Proprietary system delivers complete destruction with cost and emissions advantages, positioning for future commercial wins.
Performance Analysis
Perma-Fix’s Q3 results underscored a material transformation in its core business economics. While total revenue was nearly flat year-over-year at $16.5 million, gross profit more than doubled, and gross margin expanded to 14.6% from 7.9% in the prior year. This margin expansion was anchored by a dramatic 45% year-over-year jump in treatment segment revenue to $13.1 million, which now constitutes nearly 80% of the company’s total revenue base. Segment gross margin reached 17.3%, up sharply from 4.5%, reflecting both higher throughput and a more favorable waste mix.
Backlog momentum was a key theme, with treatment backlog ending at $15.4 million, up from $7.9 million a year ago, signaling improved visibility into 2026. Waste sales rose 74% to $14.6 million, driven by higher plant input, international shipments, and execution across commercial and DOE projects. Automation and digital scheduling initiatives contributed to a 38% sequential gross margin increase, as operational discipline translated into EBITDA improvement and throughput gains.
- Treatment Segment Outperformance: The core treatment business delivered 45% revenue growth and nearly quadrupled margin, cementing its centrality to Perma-Fix’s model.
- Backlog Growth Drives Visibility: A $15.4 million backlog, nearly doubling year-over-year, provides a revenue floor and supports future capacity planning.
- Operational Leverage from Automation: Investments in plant optimization and digital scheduling are now yielding higher productivity and cost efficiency.
With international waste shipments on schedule and new DOE-linked contracts ramping, Perma-Fix is shifting from episodic project revenue to a model emphasizing recurring, high-margin streams and long-term contractual stability.
Executive Commentary

Strategic Positioning
1. Hanford DFLAW Designation Creates Decades-Long Revenue Stream
Perma-Fix Northwest’s selection as the commercial pathway for Hanford’s DFLAW secondary waste establishes a recurring, multi-decade revenue opportunity. The DOE’s direct-feed low-activity waste facility, now in “hot commissioning,” will generate high volumes of waste requiring off-site treatment. This designation cements Perma-Fix as a critical link in the DOE’s environmental cleanup chain, with shipments expected to begin in late Q4 or early Q1 2026 and ramp up as DOE throughput increases.
2. Automation and Labor Stability Unlock Operational Scale
Automation, digital scheduling, and plant optimization are now delivering tangible productivity gains, with throughput and safety both improving. The recent union transition at Perma-Fix Northwest under UA local 598 enhances labor stability and enables multi-shift operations, aligning workforce capacity with DOE’s ramping waste volume requirements.
3. PFAS Destruction Tech Advances Commercial Prospects
The proprietary PermaFast system at the Florida facility achieved complete PFAS destruction at a 10% to 20% cost advantage over incineration and with zero air emissions. Following Q3 upgrades, system reliability and throughput improved, positioning Perma-Fix for commercial expansion as regulatory and customer demand for PFAS solutions rises.
4. International Waste Shipments Diversify Revenue Base
Continued processing of European and North American waste streams, along with evaluation of new shipments tied to upcoming EU programs, provides both backlog stability and geographic revenue diversity. This international exposure reduces reliance on any single customer or project cycle.
Key Considerations
This quarter marked a clear pivot from project-based volatility to a model anchored in recurring, contract-driven revenue and margin leverage. The Hanford designation, automation gains, and PFAS technical milestones collectively reshape Perma-Fix’s risk and opportunity profile heading into 2026.
Key Considerations:
- DOE Cleanup Pipeline: Hanford’s DFLAW ramp is a structural tailwind, but actual shipment timing and DOE throughput targets will determine revenue cadence.
- Execution on Throughput: Realizing margin potential depends on continued plant optimization and labor stability, especially as multi-shift operations scale.
- PFAS Commercialization Path: Early technical wins must translate into repeatable, scalable contracts to unlock this segment’s full value.
- Backlog Conversion: Sustained backlog growth is positive, but conversion to cash flow will be watched closely, especially as international shipments and DOE programs advance.
Risks
Perma-Fix faces timing and execution risk around DOE Hanford shipment ramp-up, as well as potential regulatory or technical hurdles in scaling PFAS destruction commercially. Fixed cost absorption and labor efficiency remain critical as throughput grows. Any delays in DOE waste characterization or international shipment schedules could impact backlog conversion and near-term cash flow.
Forward Outlook
For Q4 2025 and into 2026, Perma-Fix expects:
- Initial Hanford DFLAW waste shipments to begin late Q4 or early Q1 2026, with volume ramping through DOE’s internal targets.
- Continued international waste shipments and evaluation of new EU-related programs for additional backlog.
For full-year 2025, management reiterated a focus on:
- Margin expansion through operational discipline and automation.
- Commercialization of PFAS destruction technology.
Management highlighted that DOE’s tri-party agreement allows up to three years to reach design capacity, but internal DOE targets suggest a faster ramp, and Perma-Fix is fully prepared to meet required throughput.
- DOE shipment cadence will be the key watchpoint for 2026 revenue realization.
- PFAS commercialization and international backlog conversion will be critical to sustaining momentum.
Takeaways
Perma-Fix’s Q3 marked a structural inflection, with margin expansion, backlog growth, and a shift toward recurring, high-value contracts. The Hanford program, automation benefits, and PFAS advances collectively reposition the business for multi-year visibility and scale.
- DOE-Linked Recurring Revenue: The Hanford DFLAW designation transforms Perma-Fix’s long-term revenue profile, anchoring the business in DOE’s multi-decade cleanup mission.
- Margin and Throughput Leverage: Plant automation and labor stability are now driving higher margins and operational resilience, supporting future growth.
- PFAS Upside Remains Early-Stage: While technical milestones are promising, commercial adoption and repeatable contracts are needed for this segment to materially impact results.
Conclusion
Perma-Fix enters 2026 with a strengthened backlog, secured DOE pathway, and proven margin leverage from operational investments. The company’s pivot to recurring, contract-driven revenue and technical leadership in PFAS positions it for durable growth, but execution on DOE ramp-up and PFAS commercialization will determine the pace and scale of value creation.
Industry Read-Through
Perma-Fix’s Hanford win signals intensifying demand for specialized nuclear and hazardous waste treatment providers as the DOE’s environmental cleanup accelerates. The company’s automation and digital scheduling gains highlight the operational leverage available to niche environmental service firms that invest in plant optimization. PFAS destruction’s early cost and emissions advantages may foreshadow broader adoption pressure for legacy incineration players, as regulatory scrutiny of “forever chemicals” intensifies. International waste shipment activity suggests that cross-border hazardous waste flows remain robust, with EU regulatory cycles likely to drive new demand in 2026 and beyond.
