PERMA FIX ENVIRONMENTAL SERVICES INC

There is no other material change from the risk factors previously disclosed in our Form 10-K for the year ended December 31, 2024, and our Form 10-Q for the quarter ended June 30, 2025, except as follows.

The following additional Risk Factor under “Risks Relating to our Business Operations” is as follows:

A prolonged federal government shutdown may materially impact our results of operations.

On October 1, 2025, the U.S. federal government entered into a partial shutdown as Congress failed to pass a new fiscal year funding bill. As a result of the government shutdown, we have been recently informed by certain government related clients that waste shipments are likely to be delayed until the government shutdown is resolved. Although the impact of the government shutdown has been limited at this time, a prolonged shutdown may create uncertainty and disruption for us from additional delayed and/or cancelled waste shipments, suspension and/or slowdown of active projects, and/or delayed/cancelled procurement requests. Additionally, the recent government shutdown has resulted in furloughed and terminated employees which may result in contract award delays, delayed payments for services already rendered and restricted communication with agency counterparts who may not be working. These aforementioned impacts could negatively impact our result of operations and liquidity, the extent of which is unknown at this time. However, we believe that negative impact to our results of operations and liquidity from a prolonged government shutdown may be lessened by our Treatment Segment backlog, along with increased receipts from international and commercial clients.
