ADA-ES ANNOUNCES GAINS IN REVENUE AND NET INCOME FOR THE FOURTH QUARTER AND
YEAR

Littleton, CO - March 9, 2006 - ADA-ES, Inc. (NASDAQ:ADES) today announced
financial results for the fourth quarter and year ended December 31, 2005.
See attached tables.

Fourth Quarter Financial Highlights - versus fiscal 2004 fourth quarter
*  Total revenues rose 44% to $3.3 million.
*  Operating income was up 90% to $240,000.
*  Net income more than doubled to $213,000 or $0.04 per diluted share from
$97,000 or $0.02 per diluted share in the same period last year.  Earnings
per diluted share for the fourth quarter of 2005 were calculated on 17% more
shares outstanding than in the fourth quarter of 2004 due to the successful
completion of a 789,089-share private equity placement in October 2005.

2005 Financial Highlights - versus fiscal 2004
*  Total revenues were up 31% to $11.0 million.
*  Operating income grew 70% to $651,000.
*  Net income increased 97% to 663,000 or $0.13 per diluted share from
$336,000 or $0.08 per diluted share in 2004.  Earnings per diluted share for
2005 were calculated on 23% more shares outstanding than in 2004 due to the
aforementioned private equity placement.

Dr. Mike Durham, President of ADA-ES, stated, "2005 was a year of continued
growth and development for ADA-ES.  We surpassed our goal of 20% revenue
growth for the year due to strong performance in our fastest-growing segment.
Our mercury emission control sales grew 48%, stemming from: 1) commercial
sales of activated carbon injection (ACI) systems and related testing
services, 2) mercury measurement services and demonstrations, and 3) field
activities in Department of Energy-supported programs.  I am also pleased to
report strong operating leverage for the fourth quarter and year; operating
income grew at more than twice the rate of revenues during both periods."

Dr. Durham continued, "During 2005, the commercial market for controls for
mercury emissions from coal fired plants began in earnest, and ADA-ES signed
its first three commercial contracts of this nature.  We expect this market
to grow significantly in 2006.  In this regard, last week we announced
contracts for three more commercial systems.  Under our current commercial
contracts, we are supplying a total of six ACI systems, valued at
approximately $1 million each, which are expected to be installed at various
power plants in the U.S. and become operational during 2006 and 2007.  The
timing on each program is different, but we expect that some sites will begin
injecting activated carbon by the end of the 2006 third quarter.  ADA-ES
provides activated carbon sorbent, in partnership with NORIT Americas, as a
key component to reducing mercury emissions. The commissions we would receive
from such sorbent sales are expected to provide an important continuous
revenue stream for the Company and serve as a solid foundation for continued
growth in future years.

"Additionally, the U.S. Department of Energy's National Energy Technology
Laboratory (DOE/NETL) recently selected ADA-ES to perform new full-scale
field tests of mercury control technology at two coal-fired power plants. We
expect to recognize $7.5 million in revenues from these projects over the
next two to three years."

Dr. Durham concluded, "We continue to leverage our expertise, strategic
relationships, and position in the emerging commercial mercury control market
to further the Company's growth.  With our recent capital infusion, we have
the financial flexibility to capitalize on exciting opportunities in this
market.  Given our current contracts, as well as the commercial bid requests
we are receiving, we expect overall revenue growth of approximately 35% in
2006, and continue to be very optimistic about ADA-ES' long-term outlook."

Based on ADA-ES' current compensation structure, the Company believes that
Financial Accounting Standard (FAS) 123R, which relates to expensing stock
options, will not have a significant impact on expected 2006 operating
results.
