Perma-Fix Environmental (PESI) Q1 2025: Waste Backlog Surges 30% as Hanford and PFAS Catalysts Build
Perma-Fix Environmental’s Q1 2025 results reveal a business at a strategic inflection, with a 30% jump in waste backlog and accelerating Hanford and PFAS momentum offsetting near-term procurement delays. Management’s operational reset and targeted investments are positioning the company for a material second-half ramp, with sustainable, high-visibility waste streams and regulatory tailwinds in focus. Investors should monitor execution on Hanford throughput and PFAS commercialization as Perma-Fix enters a period of structurally higher backlog and multi-year project runway.
Summary
- Backlog Expansion: Perma-Fix’s waste backlog rose 30%, driven by Hanford and international volumes.
- PFAS Commercialization: First federal PFAS shipments and system upgrades advance the company’s position in a fast-growing regulatory market.
- Second-Half Ramp: Operational investments and federal project visibility set up for a stronger H2 2025.
Performance Analysis
Perma-Fix delivered incremental revenue growth and a marked improvement in gross profit, despite a challenging start to the year as federal procurement delays and project timing weighed on top-line expansion. The treatment segment saw a moderate revenue increase, underpinned by a surge in waste receipts late in the quarter, while the services segment experienced a slight revenue decline due to delayed project starts, though gross margins improved significantly from disciplined cost controls and better project mix.
Backlog is now a key signal, with the waste treatment backlog reaching $10.2 million, up 30% from year-end and approaching historical highs. Hanford waste streams, which have doubled versus recent years, are now providing sustainable, multi-year production visibility. SG&A expenses increased, reflecting executive hiring and readiness for volume ramp, but the company maintained a stable net loss year-over-year as gross profit rebounded. Cash burn was elevated due to working capital and targeted capex, with a healthy cash balance providing runway for ongoing investments.
- Gross Margin Recovery: Both segments delivered higher gross profit, reversing last year’s gross loss and validating recent cost initiatives.
- Hanford Waste Receipts: Monthly Hanford receipts have risen to $2-3 million, representing a structural step-change in baseline volume.
- PFAS Revenue Initiation: First commercial PFAS shipments and cost-reducing upgrades set the stage for meaningful revenue scaling in late 2025.
International waste receipts and a pipeline of federal and commercial projects round out a diversified backlog, with the stage set for a H2 inflection as operational throughput catches up to rising demand.
Executive Commentary
"After a slow start, waste receipts began to improve toward the end of the quarter, contributing to a backlog that grew to more than $10 million by quarter end, up approximately 30 percent from where we were in 2024... Our PFAS program continues to advance on multiple fronts. We received our first commercial shipments from the federal government with additional approvals pending."
Mark Duff, President and CEO
"Gross profit for the quarter was $657,000 compared to gross loss last year of $620,000 in Q1 of 24. Treatment segments gross profit increased by 302,000 compared to prior year based on higher revenue and lower variable costs related to waste mix and improved productivity."

Strategic Positioning
1. Hanford and Federal Waste Streams
Hanford is now a multi-year anchor client, with monthly receipts up 100% and expected to remain elevated as the Direct Feed Low Activity Waste (DFLAW, Hanford vitrification program) and tank closure missions ramp. The company is positioned as a core subcontractor on the Integrated Tank Disposition Contract (ITDC), with sustainable, recurring waste streams and a 15-year contract underpinning visibility. Management expects this to drive high-margin recurring revenue starting in Q4 and beyond.
2. PFAS Commercialization and Regulatory Tailwinds
PFAS (per- and polyfluoroalkyl substances, persistent environmental contaminants) is emerging as a distinct growth engine, with first federal shipments, new system upgrades, and a second-generation unit coming online in Q4 that will triple capacity. State-level regulation and EPA prioritization are accelerating demand, and Perma-Fix’s cost-competitive destruction technology is winning commercial interest from large generators. Management targets $1 million monthly PFAS revenue run-rate post-deployment, with a $20 million annualized goal.
3. Operational Reset and Throughput Investments
Significant hiring, training, and facility upgrades in Q1 are now translating into higher throughput and production efficiency, especially at the Perma-Fix Northwest facility. The new COO, with deep industry experience, is driving operational discipline and cost alignment. These steps are critical to converting backlog into revenue and margin as volumes ramp through the year.
4. International and Diversified Pipeline
International waste receipts from Canada, Mexico, and Germany reached $7 million in the quarter, with more scheduled for Q2. The company is also progressing on European partnerships (notably JRC Italy) and remains active in bidding on DOE and DOD contracts across the U.S., including West Valley and Y-12. This diversification reduces dependency on any single project or geography.
5. Capital Allocation and Cash Position
Capex is targeted at $5-6 million for 2025, with a mix of sustaining investments and the new PFAS reactor build. The company ended Q1 with $25.7 million in cash, providing ample liquidity for growth initiatives and working capital needs as project activity accelerates.
Key Considerations
Perma-Fix is navigating a transition from project-driven lumpiness to a more sustainable, backlog-driven model anchored by federal and PFAS demand. The quarter’s results highlight the importance of operational execution and backlog conversion as the company enters a structurally higher volume environment.
Key Considerations:
- Backlog-to-Throughput Conversion: Timely ramp-up of plant capacity and workforce productivity is essential to realize revenue and margin from the expanded backlog.
- PFAS Commercial Scale: Successful deployment and market adoption of the second-generation PFAS unit will be pivotal for outsized growth and margin expansion.
- Federal Budget Stability: DOE and NNSA funding remains robust, but continued political support is needed to sustain multi-year project pipelines.
- Competitive Dynamics: Hanford grouting and PFAS destruction markets are attracting new entrants; Perma-Fix’s local presence and technology advantage must be maintained.
- International Execution: Converting international partnerships and waste receipts into profitable, recurring business remains a strategic lever and execution test.
Risks
Project timing and federal procurement cycles remain unpredictable, with delays or budget changes potentially impacting revenue recognition and cash flow. PFAS regulatory adoption is uneven across states, and competitive intensity in both Hanford and PFAS markets could pressure margin or delay scale. Execution risk around throughput, staffing, and capex management is elevated as the business scales. Investors should monitor for signs of backlog conversion lag or margin erosion as volumes ramp.
Forward Outlook
For Q2 2025, Perma-Fix management signaled:
- Material improvement in revenue and profitability as Hanford and international waste receipts accelerate.
- Continued ramp in PFAS commercial activity, with second-generation unit on track for Q4 deployment.
For full-year 2025, management maintained a constructive outlook:
- Backlog and project pipeline support a stronger second half, with potential for recurring, high-margin revenue from Hanford and PFAS.
Management highlighted five drivers for the year: growing waste treatment backlog, improved federal procurement visibility, Hanford DFLAW ramp, PFAS technology traction, and execution on large-scale domestic and international opportunities.
- Backlog conversion and operational throughput are the near-term focus.
- Regulatory and funding visibility underpin the multi-year growth thesis.
Takeaways
Perma-Fix’s Q1 signals a pivot to backlog-driven growth, with Hanford and PFAS providing structural tailwinds and project visibility.
- Backlog Is Now the Key Leading Indicator: The 30% increase in waste backlog and surge in Hanford receipts set a higher baseline for 2025 and beyond.
- PFAS and Federal Programs Anchor the Growth Narrative: Execution on PFAS commercialization and Hanford throughput will determine the pace and profitability of the ramp.
- Operational Discipline and Capital Allocation Are Crucial: Management’s investments in people, plant, and technology must translate into sustained margin and cash flow as volumes scale.
Conclusion
Perma-Fix enters a pivotal phase, with backlog, federal project visibility, and PFAS commercialization converging to support a multi-year growth runway. Execution on throughput, regulatory adoption, and international expansion will dictate the company’s ability to convert backlog into durable earnings power.
Industry Read-Through
