Perma-Fix Environmental Services, Inc. (NASDAQ:PESI) reported fourth-quarter results on Tuesday that came in below analyst expectations.
The company’s shares fell about 8.7% in pre-market trading following the release.
The nuclear waste management company reported a quarterly loss of $0.31 per share, missing the consensus analyst estimate of $0.09 per share. Revenue totaled $15.7 million, also below the analyst forecast of $18.1 million, although it increased 6.9% compared with $14.7 million in the same period a year earlier.
Revenue growth was driven by the Treatment Segment, which climbed 29.0% to $11.4 million from $8.8 million as a result of higher waste processing volumes. Meanwhile, the Services Segment declined 26.4% to $4.3 million from $5.9 million, mainly due to fewer project assignments and the effects of the temporary U.S. federal government shutdown in October 2025.
For the full year 2025, the company reported revenue of $61.7 million, up from $59.1 million in 2024. Net loss for the year totaled $13.8 million, or $0.75 per share, compared with a net loss of $20.0 million, or $1.33 per share, in the previous year.
The 2025 results included a $2.7 million increase in the environmental remediation reserve related to the company’s Perma-Fix of South Georgia subsidiary.
“During 2025, we focused on strengthening Perma-Fix’s operational foundation and positioning the Company for the next phase of growth tied to the U.S. Department of Energy’s Hanford cleanup mission,” said Mark Duff, President and Chief Executive Officer.
The company also reached an operational milestone with the renewal of the permit for its Perma-Fix Northwest facility, expanding its authorized processing capacity to around 1.2 million gallons of liquid mixed waste per year. By year-end, the treatment backlog had increased about 51% year over year to $11.9 million, while international revenue rose approximately 163% year over year to $6.4 million.
