FOR IMMEDIATE RELEASE

ADA-ES PROVIDES OPERATING UPDATE

ANNOUNCES PRESENTATION AT BAIRD 2012 INDUSTRIAL CONFERENCE AND

APPOINTS NEW DIRECTOR

Reiterates Optimism for Emissions Control and Refined Coal Segments

Highlands Ranch, CO – November 1, 2012 – ADA-ES, Inc. (NASDAQ: ADES) (“ADA”) today announced that Michael D. Durham, President & CEO, and Mark McKinnies, SVP & CFO, are scheduled to present at the Baird 2012 Industrial Conference in Chicago on Monday, November 5, 2012 at 3:35 p.m. CT. A copy of the slides to be used at this event will be available via the Investor Information section of www.adaes.com on or before November 5, 2012, and will also be filed on Form 8-K with the Securities and Exchange Commission.

In advance of the Baird presentation, ADA is providing an update on the Company’s progress along a number of fronts.

Emissions Control

Refined Coal

ADA’s Clean Coal Solutions, LLC (“Clean Coal”) joint venture now has eight Refined Coal (“RC”) facilities in full-time operation on 15 coal-fired boilers. The seven RC facilities that were operational during Q3

2012 (the eighth RC facility began operating in October) produced approximately 5.3 million tons of RC. Based on year-to-date usage, ADA expects these eight RC facilities will, in the aggregate, produce approximately 16 million tons of coal in 2012, or approximately 20 million tons on an annual basis.

Dr. Durham commented, “Closings of several deals with power companies and tax equity partners for our RC facilities were delayed in Q2 and Q3 for various reasons, including: permitting, regulatory approval, corporate financial restructuring of related third parties, changes in plant ownership, changes and retirements of personnel involved in the negotiations, the need to involve additional parties in the transactions, and uncertainties in the tax credit community. As our previous disclosures have indicated, because of the complexities of each RC deal and the number of externalities that are outside our direct control and involvement, there was potential for delays beyond our initial estimates of 6-9 months to close the transactions.

“As demonstrated by the recent information from Minnkota Power regarding its MR Young plant, the factors that are within ADA’s control, such as the effectiveness of the technology, the operation of the RC facilities, and the satisfaction of the utilities burning the RC, have produced very favorable results. We continue to drive toward the goal of producing RC from all 28 placed in service facilities while remaining flexible to address as best we can those variables that are outside our control.

“Despite the recent delays, we do not expect any changes that may result from variables outside our control to have a material impact on the expected size of our market or the future long term economics for our RC business segment. We believe that once all new and existing RC facilities are leased or sold to others and become fully operational, they will achieve an annualized segment rental revenue rate of approximately $200 million; this revenue figure excludes approximately $250—$300 million in ongoing coal sales and raw coal purchases for RC facilities that Clean Coal is expected to operate in the long-term for its own account. These revenue rates would be expected to generate approximately $100 million in segment income to ADA after payments to minority partners, including an estimated $30 million in tax credits to be generated by RC facilites operated by Clean Coal. The projected segment revenue and income are expected to continue through 2021.”

Dr. Durham continued, “Based upon the status of operations and negotiations on RC facilities, we expect to report consolidated RC segment revenues of approximately $190 million in 2012, comprised of $40 million in rental revenues and $150 million in coal sales and raw coal purchases. Tax credit benefits and segment income for 2012 are projected to total approximately $22 million, which will include approximately $16 million of tax credits apportioned to ADA associated with the operations of RC facilities that have either yet to be monetized or are being operated by Clean Coal for its own use.”

Dr. Durham concluded, “The increased market activity following the finalization of MATS in April has supported our confidence for significant growth in revenues, profits, and cash flows in 2012 and 2013 from our combined activities.”
