FOR IMMEDIATE RELEASE

ADA-ES REPORTS FOURTH QUARTER AND YEAR END 2006 RESULTS

2006 Revenues Rise 40%; Fuels Enhanced Growth Opportunities

Littleton, CO – March 13, 2007 – ADA-ES, Inc. (NASDAQ:ADES) today announced financial results for the year and fourth quarter ended December 31, 2006. See attached tables.

For 2006, total revenues rose 40% to $15.5 million. ADA-ES reported an operating loss of $12,000 compared to operating income of $651,000 in 2005, due to activities related to the Company’s growth strategies. For example, the Company recognized $411,000 in M&A expenses related to its plans to vertically integrate into the production of activated carbon. In addition, the Company recorded $618,000 in expenses related to its Refined Coal efforts, which resulted in a joint venture with an affiliate of NexGen Resources Corporation, while the initial payment of $1,000,000 by NexGen to the Company was recorded, net of taxes, as an increase in equity rather than as revenues. Net income was $377,000 or $0.07 per diluted share versus $663,000 or $0.13 per diluted share in 2005. Net income per diluted share was calculated on 12% more shares outstanding due to a 790,000-share private equity placement in October 2005.

For the fourth quarter, total revenues increased 25% to $4.1 million. General and administrative expenses increased primarily due to the implementation of stock option expensing per SFAS 123R ($83,000), expenses resulting from additional employees (a $162,000 increase), and higher legal and director fees and expenses incurred to maintain compliance with public company regulations (a $135,000 increase). Net income for the quarter was $223,000, or $0.04 per share, compared to $213,000, or $0.04 per share in the fourth quarter of 2005.

Dr. Mike Durham, President of ADA-ES, stated, “Our revenue growth for the year surpassed our expectations and was driven by continued strength in our mercury emission control segment. Sales in this area grew 35% during the fourth quarter, and 55% for the year. By the end of 2006, we had won contracts covering 12 activated carbon injection (“ACI”) systems for mercury control. We will continue to generate revenues from eight of these contracts during 2007. Thus far in 2007, we have won awards for five additional ACI systems. Additionally, we have the potential to sell another six units via an existing contract if our customer exercises all of their options. Currently, ADA-ES has secured contracts equivalent to a market share greater than 55% of the ACI systems sold to date.

“We are winning this business by capitalizing on our key strategic advantages, including the extensive experience and relationships we developed by conducting more than 30 full-scale demonstrations of activated carbon injection technology at power plants across the country. The mercury market is growing rapidly, and we expect to bid on between 50 and 100 systems over the next 2 years. As a result, we are more than doubling the number of engineers in our commercial equipment group who are integral in the preparation of bids, proposals and contracts. Proposals are submitted three to nine months prior to contract awards; therefore, we incur related expenses prior to revenues from new contracts. 


Dr. Durham continued, “We remain optimistic about the Company’s long-term prospects based primarily on the following growth areas:

o  

Continued expansion of the mercury emission control market, which is projected to be a multi-billion dollar a year business if/when Congress passes legislation to further strengthen existing regulations that affect most of the country’s 1,100 plus coal-fired boilers. This growing market is creating continued strong demand for our mercury control products and services. Currently, there are 12 states with mercury control rules and 13 states considering regulations stricter than the federal government’s CAMR rule.


o  

To fully take advantage of the Company’s position in the mercury market, ADA-ES has committed to continue the development of an activated carbon manufacturing facility, with the purpose of satisfying a significant portion of the shortage in activated carbon supply we expect for the rapidly expanding mercury control market. The large-scale production facility is being designed to maximize efficiency and produce the most cost-effective product for the mercury control market. Approved and funded activities include plant design, securing options on various desirable properties for the plant, and permitting, as well as specifying and sourcing of key capital equipment, and negotiating with potential financial partners. We expect the build-out to cost approximately $200 million, and plan to finance it through a combination of equity and debt funding from financial and strategic partners.


o  

The Company has an attractive position in Refined Coal, where we believe our technology is applicable to a target market of approximately 60 million tons of Refined Coal per year, which would amount to a market potential of approximately $150 million per year. Importantly, initial interest from the market appears strong, and our business model provides a basis for rapid development and implementation of new product. During the fourth quarter, we formed a 50:50 Joint Venture with NexGen, which will do business as Clean Coal Solutions, LLC. NexGen has paid ADA-ES $1 million to date, which is reflected in our shareholders’ equity, and, if the tax credits are assured, has the right to maintain a 50% position in the JV by paying ADA-ES an additional $4 million, payable in 8 quarterly payments of $500,000 each, beginning as early as the 4th quarter of 2007. Revenues from this JV would be generated from monetization of tax credits, which are eligible to commence in 2009.”


Dr. Durham concluded, “We look forward to reporting on ADA-ES’ continued development.”

The Company will delay the filing of its Annual Report on Form 10-K for the fiscal year ended December 31, 2006 in order to complete the review and certifications required by the Sarbanes-Oxley Act. The Company plans to file its Form 10-K on or before March 30, 2007.
