FOR IMMEDIATE RELEASE

ADA-ES REPORTS SECOND QUARTER RESULTS

LITTLETON, CO – August 8, 2007 – ADA-ES, Inc. (NASDAQ:ADES) today announced financial results for the second quarter and six months ended June 30, 2007. See attached tables.

Total revenues for the quarter increased 49% to $4.9 million as compared to the second quarter of 2006, while sales in the Company’s mercury emission control segment rose 75% to $4.6 million. The Company’s gross margin was 30.9% in the quarter, versus 34.6% in the second quarter of last year, due to slightly lower margins realized on activated carbon injection (“ACI”) systems as the market is developing and pricing pressures increased as a result of competition, and decreased Flue Gas Conditioning (“FGC”) revenues, some of which were sales of a licensed product that carries lower margins. General and administrative expenses increased $285,000 during the quarter, primarily due to higher legal, consulting, outside labor and administrative wage costs, but declined as a percentage of revenues to 24% from 28%. ADA-ES reported an operating loss of $274,000, compared to an operating loss of $140,000 in the second quarter of 2006. The Company had net income of $55,000 or $0.01 per diluted share, versus net income of $44,000 or $0.01 per diluted share in the 2006 period.

For the six-month period, total revenues rose 27% to $8.8 million, and sales in the Company’s mercury emission control segment increased 43% to $8.2 million. Operating loss was $586,000 versus operating income of $24,000 for the same period last year. Net income was $32,000 or $0.01 per diluted share for the current six-month period compared to $282,000 or $0.05 per diluted share for the same period in 2006.

Dr. Michael Durham, President & CEO of ADA-ES, stated, “Our mercury control revenues grew at a very attractive pace during the quarter, with commercial ACI equipment sales of $2.5 million becoming our dominant revenue source. We are optimistic about our prospects for continued growth in the balance of the year as we start to recognize more significant ACI system revenues.”

Dr. Durham continued, “Our financial results continue to reflect our focus on future growth and our aggressive approach to leveraging our position in mercury control and maximizing the Company’s future earnings. To position ADA-ES to be able to respond to an anticipated market for 50-100 mercury control systems during 2007-2008, we have expanded the number of engineers in our commercial equipment design and proposal group, enhanced our designs, and increased our potential suppliers of components.”


Dr. Durham concluded, “We remain extremely enthusiastic about the Company’s long-term prospects for growth, based on our current position in the mercury control market, and the rapidly growing demand for mercury control technology and activated carbon. The evidence of our commitment to this market and our progress can be seen in the filing of permits for new activated carbon production lines in Louisiana, which positions the Company to be a long-standing market leader. Additionally, progress is being made on our other growth area, refined coal, and carbon dioxide emission control presents further upside potential.”
