Reiterates Growth Forecasts, Driven by Significant Progress at Refined Coal Segment

Experiencing Higher Coal Usage at Coal-Fired Power Plants

Highlands Ranch, Colorado – July 16, 2012 – ADA-ES, Inc. (NASDAQ: ADES) (“ADA”) announced today that it will hold its annual meeting of shareholders as planned at 9:00 a.m. (local time) on July 19, 2012 at its offices located at 9135 South Ridgeline Boulevard, Suite 200, Highlands Ranch, Colorado. At the meeting, ADA shareholders will be asked to consider and vote on proposals to elect nine directors; ratify the Audit Committee’s selection of Ehrhardt Keefe Steiner & Hottman PC as ADA’s independent registered public accounting firm for the fiscal year ending December 31, 2012; approve Amendment No. 1 to the Amended and Restated 2007 Equity Incentive Plan; and approve the Amended and Restated 2010 Non-Management Compensation and Incentive Plan. Further information regarding these proposals is available in the proxy statement that ADA filed with the Securities and Exchange Commission (SEC) (www.sec.gov) on June 6, 2012.

INVESTOR UPDATE

At the annual meeting of shareholders, ADA management will also update investors on the Company’s progress along a number of fronts, including:

ADA will also provide additional information regarding the previously announced restatement of its financial statements for the fiscal year ended December 31, 2011 and for the quarterly periods ended June 30, 2011, September 30, 2011 and March 31, 2012, related to the accounting treatment of the sale of a 15% equity interest in Clean Coal to an affiliate of The Goldman Sachs Group, Inc. The Company will also discuss the previously announced, possible restatement of its 2010, 2011, and first quarter 2012 financial statements based upon discussions with the SEC regarding the reporting of deferred tax assets that are included on the Company’s balance sheets. As previously disclosed in a press release and Form 8-K dated June 20, 2012, the restatement caused by the accounting treatment of the equity interest in Clean Coal will not impact ADA’s statements of operations for the above-referenced periods, including historical revenues, net (loss) income, and earnings (loss) per share, nor will it affect items such as cash and cash equivalents or liquidity. In addition, while any restatement due to the accounting treatment of our deferred tax assets would impact the reporting of the deferred tax assets and our net losses for the above-mentioned periods, the availability of the cumulative net operating losses and tax credits for offsetting future net income in profitable years would not be impacted. If in a subsequent fiscal period we reduce such allowances, our net income for such period would increase to the extent of such reduction.

A copy of the slides to be used at the annual meeting will be available via the Investor Information section of ADA’s web site, www.adaes.com, on or before July 19, 2012, and will also be filed on Form 8-K with the SEC.
