Perma-Fix Reports Preliminary Results for Fiscal 2018

Announces $17 million in new contract awards for 2019

ATLANTA, GA / ACCESSWIRE / March 28, 2019 / Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) (the ''Company'') today announced preliminary results for the fourth quarter and full year ended December 31, 2018. Revenue for the year ended December 31, 2018 is expected to be $49.5 million compared to $49.8 million in prior year. Net loss attributable to Common Stockholders for the year ended December 31, 2018 is expected to be $1.4 million compared to $3.7 million in prior year.

Mark Duff, Chief Executive Officer, stated, ''Though the results in 2018 did not meet our expectations, we are excited with the changes in the Company over the past several months including the completion of the cleanup phase of the M&EC facility closure and the startup of the GeoMelt technology. In addition, we are beginning to realize a return on our business development strategy as we have been awarded several new projects in March that will further increase our funded backlog and bolster our Services Segment beginning in the second quarter of 2019. These wins, which will be formally signed and announced in the coming weeks, include remediation work in Canada as well as several DOE locations throughout the United States. We expect the total contract value of these awards to collectively be approximately $17 million, be earned in 2019 and include significant out-year potential. We believe these awards are a direct result of the improvements we made last year within our business development organization.''

The Company is in the process of completing the audit of the results for the fourth quarter and full year ended December 31, 2018, which will be separately announced and included in the Company's Form 10-K to be filed with the Securities & Exchange Commission.
