Perma-Fix Announces 18.6% Year-Over-Year Sales Growth,

Improved Margins, and Increased Profitability for the Second Quarter of 2010

ATLANTA – August 5, 2010 – Perma-Fix Environmental Services, Inc. (NASDAQ: PESI) today announced results for the second quarter ended June 30, 2010.

Dr. Louis F. Centofanti, Chairman and Chief Executive Officer, stated, “The 18.6% year-over-year growth in our second quarter revenue to $28.1 million was the result of additional on-site service work at Hanford and an increase in treatment of higher activity waste.  Our Nuclear segment generated $25.2 million of revenue during the quarter, an increase of 21.5% over the prior year.  The gross profit for the quarter was $6.7 million, which included an $844,000 charge related to an increase in the environmental reserve at one of our industrial facilities. Excluding this charge, gross profit would have increased 39.1% to $7.6 million, and our gross margin would have increased 398 basis points to 27.0%.  This gross margin increase directly reflects the increase in high activity waste in our revenue mix.  We achieved $2.9 million of operating income for the quarter and operating margin increased 376 basis points to 10.4%.  We generated $4.1 million of EBITDA and earnings per share of $0.03 for the second quarter of 2010, as compared to $2.8 million of EBITDA and earnings per share of $0.01 for the second quarter of 2009. We achieved these strong results despite the aforementioned environmental reserve and $904,000 of non-cash income tax expense related to our net operating loss carryforwards that we recorded in the second quarter of 2010.”

“We are also pleased to report that Perma-Fix was recently awarded its first direct Department of Energy (DOE) prime contract for Low-Level and Mixed Low-Level Radioactive and Hazardous waste treatment services, which will allow us to bid directly on low level and hazardous waste treatment services.  We were one of only four companies recently awarded these Indefinite Delivery/Indefinite Quantity (ID/IQ) contracts, which are utilized by the DOE when exact quantities and timing of waste shipments are unknown. DOE’s Office of Environmental Management determined that it needed an efficient mechanism to contract with companies capable of treating large volumes of diverse radioactive wastes generated at its facilities throughout the United States.”

“Earlier this year, we completed the design, construction, and installation of a new proprietary process to treat Tritium contaminated waste.  During the second quarter we completed an important and successful project which demonstrated our ability to treat these waste streams originating from the DOE’s Savannah River Site located in Aiken, SC.  We see the treatment of Tritium waste as an attractive new opportunity going forward.”

Financial Results

Revenue for the second quarter of 2010 increased 18.6% to $28.1 million, versus $23.7 million for the same period last year.  The increase in revenue is mainly attributable to increased on-site work at the Hanford facility in Richland, Washington and the Company’s shift into higher activity wastes.  Revenue for the Nuclear Segment increased to $25.2 million from $20.7 million for the same period last year. Revenue for the Industrial Segment increased to $2.2 million versus $2.0 million for the same period last year due primarily to higher waste volume and improved pricing. Revenue from the Engineering Segment decreased to $666,000 from $1.0 million for the same period last year.

Gross profit for the second quarter of 2010 increased 23.6% to $6.7 million versus $5.5 million for the second quarter of 2009 primarily due to higher priced wastes and the subcontract with the CH Plateau Remediation Company.  The gross profit for the quarter included an $844,000 charge related to an increase in the environmental reserve for remediation at one of our Industrial Segment facilities.

Operating income for the second quarter increased 86% to $2.9 million versus $1.6 million for the second quarter of 2009.  Net income for the second quarter of 2010 was $1.4 million, or $0.03 per share, versus net income of $751,000 or $0.01 per share, for the same period last year.  Net income in the second quarter of 2010 included $1.1 million in income tax expense, compared to only $91,000 in 2009, as 2009 included a full valuation allowance of our available net operating losses carry forward.  Net income in the second quarter of 2009 also included a loss from discontinued operations of approximately $242,000.

The Company had EBITDA of $4.1 million for continuing operations during the quarter ended June 30, 2010, as compared to EBITDA of approximately $2.8 million for the same period of 2009. The Company defines EBITDA as earnings before interest, taxes, depreciation and amortization.  EBITDA is not a measure of performance calculated in accordance with accounting principles generally accepted in the United States (“GAAP”), and should not be considered in isolation of, or as a substitute for, earnings as an indicator of operating performance or cash flows from operating activities as a measure of liquidity. The Company believes the presentation of EBITDA is relevant and useful by enhancing the readers’ ability to understand the company’s operating performance. The Company’s management utilizes EBITDA as a means to measure performance. The Company’s measurements of EBITDA may not be comparable to similar titled measures reported by other companies.  The table below reconciles EBITDA, a non-GAAP measure, to net income for the three months and six months ended June 30, 2010 and 2009.
