StockStory’s take

Perma-Fix’s third quarter results were shaped by operational setbacks at its treatment segment and timing delays in processing Hanford-related waste streams. Management pointed to postponed customer approvals and scheduled facility upgrades as main contributors to the muted profitability, despite a year-on-year increase in revenue. CEO Mark Duff cited the late arrival of necessary approvals for Hanford waste—“implementing the changes meant we didn’t reach full operations until September”—and downtime at key facilities as challenges that pushed some expected revenue beyond the quarter. The services segment, however, saw improved activity and margins, partially offsetting the headwinds in treatment.

Looking ahead, management’s guidance is underpinned by expectations for ramping DFLAW (Direct-Feed Low-Activity Waste) volumes and the full rollout of new pricing structures. Duff emphasized that increased production at Hanford, along with the transition to a new operations contractor, should drive higher waste receipts and revenue. “We expect both streams to increase as DFLAW ramps up... and we expect dry waste receipts to grow further,” he noted, positioning Perma-Fix to benefit from a multi-year opportunity. Management also highlighted regulatory milestones and ongoing permit modifications as key to unlocking further capacity and revenue streams.

Key insights from management’s remarks

Management attributed third quarter performance to delayed Hanford waste processing, facility maintenance, and the initial impact of new pricing strategies, while pointing to a growing backlog and service segment strength as positives.

• Hanford waste delays: Revenue recognition was postponed due to late customer-directed protocol changes and approvals on a major Hanford waste stream, with Duff noting, “implementing the changes meant we didn’t reach full operations until September.”
• Facility upgrades and downtime: Scheduled maintenance at Florida and Kingston, Tennessee thermal treatment facilities limited throughput, but these upgrades were completed by quarter-end and are now supporting a larger backlog.
• Pricing structure changes: The company began implementing price increases in August to offset higher labor, technology, and equipment costs. Early customer reaction was supportive, and management anticipates these increases will be fully reflected in future quarters.
• Service segment momentum: The services business benefited from new project wins, including a $24 million agreement with Lawrence Livermore National Laboratory, and improved gross margins from stronger project execution and higher utilization.
• Backlog expansion: Treatment segment backlog grew approximately 65% versus year-end 2025, reaching $19.6 million, providing improved visibility into future activity.

Drivers of future performance

Perma-Fix’s outlook is shaped by rising Hanford waste processing volumes, expanded grouting capacity, and regulatory progress for East and West area tank programs.

• DFLAW production ramp: Management expects both liquid and dry waste receipts from Hanford’s DFLAW facility to rise as the plant transitions from construction to operations, with potential for monthly volumes to double in coming quarters, materially boosting treatment revenue.
• Permitting and capacity expansion: Ongoing permit modifications with Washington State are critical to enabling future growth, as expanded grouting capacity is needed to meet Department of Energy (DOE) targets for both current and planned waste streams through 2027 and beyond.
• PFAS regulatory tailwinds: State-level mandates on phasing out PFAS-containing firefighting foams are anticipated to accelerate demand for Perma-Fix’s destruction services, with the next-generation PFAS reactor expected to triple processing capacity when operational in 2027.

Catalysts in upcoming quarters

In the coming quarters, the StockStory team will closely monitor (1) the pace of DFLAW volume increases as Hanford ramps up, (2) progress on regulatory approvals and permit modifications for expanded grouting capacity, and (3) the effectiveness of new pricing structures as they become fully embedded in the treatment segment. Additionally, we will track the commissioning of the next-generation PFAS reactor and the company’s ability to convert backlog into revenue.

Perma-Fix currently trades at $12.88, in line with $12.81 just before the earnings. In the wake of this quarter, is it a buy or sell? Find out in our full research report (it’s free).
