Perma-Fix Environmental Services (PESI) 12th Annual Waste & Environmental Services Symposium summary

Facility overview and strategic positioning

• Operates four key waste treatment plants in the U.S., with the flagship near Hanford, WA, and others in TN and FL, each specializing in various waste streams and R&D initiatives.

• International waste treatment presence is expanding rapidly, with significant waste imports from Europe, Canada, and Mexico.

• Facilities are uniquely permitted for handling classified and hazardous waste, with ongoing technology upgrades to broaden accepted waste types.

• The Hanford plant is strategically located and unionized, enhancing community integration and competitive positioning for DOE contracts.

Hanford cleanup and revenue outlook

• Hanford’s DFLAW plant is starting up after 25 years and $20B investment, with waste streams contracted to the facility for at least 10 years.

• Initial waste receipts from DFLAW expected in May, ramping to $1M/month by end of Q2, with further increases as capacity grows over the next 1-2 years.

• Additional Hanford tank waste grouting program valued at $4B over 12 years, with RFP decision expected in July; company is well-positioned due to proximity and permitting.

• Hanford-related revenue projected to rise from $3M to $7-8M per quarter starting Q2.

International and new technology initiatives

• Won a $50M contract for waste remediation in Ispra, Italy, with shipments to begin in 2027; international program revenue grew 160% in the past year.

• Developed a proprietary PFAS destruction process operating at low temperatures, offering cost and environmental advantages over incineration.

• PFAS treatment capacity is expanding, with a new Oak Ridge facility tripling daily throughput; targeting $400K/month in PFAS revenue by Q4.

• PFAS market expected to transform rapidly if EPA designates it as hazardous waste.
