First Quarter Financial Highlights - versus fiscal 2005 first quarter

--Total revenues increased 68% to $3.6 million from $2.2 million.

--Operating income rose to $164,000 from $55,000.

--Net income grew to $238,000 or $0.04 per diluted share from $95,000 or $0.02 per diluted share in the same period last year. Earnings per diluted share for the first quarter of 2006 were calculated on 16% more shares outstanding than in the first quarter of 2005 due to the successful completion of a 789,089-share private equity placement in October 2005.

Dr. Mike Durham, President of ADA-ES, stated, "We are extremely pleased with our results for the first quarter and our continued progress in our mercury emission control segment, where sales rose 94% driven primarily by the initiation of the market for commercial activated carbon injection (ACI) systems that began last summer."

Dr. Durham continued, "Thus far in 2006, we have signed contracts for six ACI systems to be delivered in 2006 and 2007, producing a total of nine commercial ACI systems, including one in partnership with a third party. As we have stated previously, based upon negotiations underway, we anticipate entering into contracts for a number of new systems during the balance of this year. Additionally, we expect to begin realizing revenues from commissions on sales of corresponding sorbents to these plants once these systems become operational, which for the first unit is likely to occur in the third quarter of this year."
