ADA-ES Engages Credit Suisse as Its Financial Advisor.

LITTLETON, Colo. -- ADA-ES, Inc. (NASDAQ:ADES) today announced that it has engaged Credit Suisse to provide financial advisory and investment banking services to assist the Company in financing the development of its first activated carbon production facility.

As previously announced, the Company expects the financing to include a combination of debt and equity totaling approximately $260 million to fund the development of a single production line, which would produce approximately 125 million pounds of activated carbon on annual basis. Based on current mercury control regulations effective in 13 states, market analyses estimate that the power industry could require up to 400 million pounds of activated carbon per year by 2010, which would essentially require nearly a doubling of current U.S. market capacity.

Dr. Michael Durham, President & CEO of ADA-ES, stated, "We are very pleased to have access to Credit Suisse's substantial resources and experience, and look forward to working with them as they provide guidance with respect to our capital plans. The vertical integration of our business is a significant opportunity for the Company, and our aggressive strategy represents a path toward a quantum growth scenario. Together we have a team that is capable of not only developing this first activated carbon production plant, but bringing on additional production lines that we believe will be needed to adhere to a potentially strict Federal mercury control regulation."
