(NASDAQ: CECE), a leading provider of air pollution control and industrial ventilation systems today announced record revenues of $56.1 million for the six months ended June 30, 2006, a 60.0% increase compared to $35.1 million for the same period in 2005. Revenues for the second quarter of 2006 increased 58.6% to $31.7 million compared to $20.0 million for the same period in 2005.

Gross profit was $9.7 million for the first six months of 2006, an increase of 51.2% or $3.3 million compared to $6.4 million for the same period in 2005. Second quarter 2006 gross profit was $5.6 million, an increase of 31.3%, compared to gross profit of $4.3 million during the same period in 2005.

Operating income for the first six months of 2006 was $1.9 million, an increase of 735% compared to operating income of $232,000 during the same period of 2005. Operating income was $1.24 million in the second quarter of 2006 compared to operating income of $1.19 million during the same quarter of 2005. Costs associated with the absorption of H.M. White and greater than expected costs on one large contract affected second quarter operating income.

Other income was $1.4 million in the second quarter of 2006 compared to $26,000 in the second quarter of 2005. $1.3 million of this second quarter 2006 income was the result of the exercise of 248,000 warrants plus $96,000 of income created by a slight decrease in the Company’s stock price which reduced the carrying value of the remaining 119,000 warrants.

Pre-tax net income for the six months ended June 30, 2006 was $1.1 million compared with a net loss of $914,000 for the same period in 2005. Pre-tax net income for the second quarter was $2.1 million as compared to $593,000 for the same period in 2005.

Net income for the quarter ended June 30, 2006 was $1.6 million or $.12 per diluted share compared with net income of $235,000 or $.02 per diluted share for the same period in 2005.

Our backlog as of June 30, 2006 was $43.7 million compared to $28.9 million as of December 31, 2005.

President, Rick Blum stated, “Second quarter results were very strong with most of the contribution coming from our contracting activities and component parts sales. Our backlog continues to grow along with our increasing level of sales and we are confident that future results will continue to reflect this improved performance.”

Chairman and CEO, Phillip DeZwirek commented that, “The turnaround in the first quarter coupled with our strong second quarter performance resulted in record revenues and operating income for the six months combined. We expect our second half to be robust as well and we anticipate additional contributions from our equipment group later in the year.”
