(NASDAQ: PESI), a global leader in nuclear waste management and environmental remediation solutions, announced today the formation of a strategic Partnership with Mirion Technologies, under the Small Business Administration’s Mentor-Protégé Program. The formation of the strategic partnership reinforces Perma-Fix’s leadership in the U.S. nuclear cleanup market in support of the Department of Energy (DOE) and its Office of Environmental Management’s mission to reduce risks from the Cold War nuclear legacy and advance safe, permanent solutions for complex radioactive and hazardous waste. “This Partnership represents a natural evolution of Perma-Fix’s strategy to expand our leadership across the DOE environmental management landscape. As cleanup missions continue to grow in complexity, we believe customers increasingly value solutions that combine specialized treatment infrastructure, radiological expertise, and disciplined execution. Perma-Fix’s waste management and remediation capabilities are the cornerstone of this Partnership, and Mirion’s instrumentation expertise further strengthens our ability to compete for and support larger, more technically demanding cleanup opportunities,” said Mark Duff, President and Chief Executive Officer of Perma-Fix. The Perma-Fix and Mirion Technologies partnership will leverage Perma-Fix’s more than 30 years of experience in nuclear waste treatment, environmental remediation, project management, and waste disposition, complemented by Mirion Technologies’ expertise in radiation detection, measurement, monitoring, and advanced nuclear instrumentation. The Partnership will focus on opportunities involving advanced waste characterization and segregation, radiological measurement and non-destructive assay, waste processing, packaging, transportation, and disposal support for complex nuclear and environmental remediation projects. Together, the Partnership is intended to support earlier and more accurate waste segregation, optimized disposal pathways, reduced disposal costs and timelines, and improved project execution across major DOE cleanup programs. The Mentor-Protégé relationship aligns with Perma-Fix’s broader strategy of expanding its participation in long-duration nuclear cleanup and waste treatment programs. As the Company continues to invest in treatment capacity, permitting, and operational readiness across its nuclear platform, management believes strategic partnerships such as this can further strengthen Perma-Fix’s ability to address emerging federal remediation opportunities, including longstanding experience at key DOE facilities such as Los Alamos National Laboratory.
