Dr. Louis F. Centofanti, Chairman and Chief Executive Officer, stated, “Perma-Fix has established a unique position within the nuclear waste treatment and nuclear services market due to our technologies, our track record and our permits. In the first quarter of 2010, our seasonally weakest period, revenue increased 18% and operating income increased by more than 97% compared to the first quarter of 2009. We achieved these results, even while our Perma-Fix II unit for radioactive organic waste treatment was temporarily shut down as we made major enhancements to the unit. With this unit expected back online in mid-May, combined with our growing on-site service work and our expansion into higher activity wastes, the outlook for 2010 is quite promising. Longer-term, we continue to develop new treatment technologies for higher activity waste and remain focused on growing our nuclear services business.”

Revenue for the first quarter of 2010 increased 17.5% to $25.9 million, versus $22.0 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 $22.9 million from $19.1 million for the same period last year. Revenue for the Industrial Segment increased to $2.3 million versus $2.1 million for the same period last year due primarily to higher waste volume and improved pricing. Revenue from the Engineering Segment decreased to $675,000 from $779,000 for the same period last year.

Operating income for the first quarter increased 97.4% to $1.5 million versus $766,000 for the first quarter of 2009. Net income for the first quarter of 2010 was $638,000, or $0.01 per share, versus net income of $548,000 or $0.01 per share, for the same period last year. Net income in the first quarter of 2010 included a $436,000 in income tax expense, compared to only $9,000 in 2009, as 2009 included a full valuation allowance of our available net operating losses carry forward. Net income in the first quarter of 2009 also included a recovery in discontinued operations of approximately $400,000 related to closure costs for Perma-Fix Treatment Services, Inc.

The Company had EBITDA of $2.7 million for continuing operations during the quarter ended March 31, 2010, as compared to EBITDA of approximately $1.9 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 ended March 31, 2010 and 2009.
