                           ADA-ES, Inc. and Subsidiary
               Notes to Consolidated Financial Statements (Unaudited)
                                   March 31, 2005

(1)  General
The accompanying consolidated financial statements were prepared in
accordance with generally accepted accounting principles and reflect all
adjustments which are, in the opinion of management, necessary for fair
representation of the financial results for the interim periods shown.  Such
statements should be considered in conjunction with Registrant's  Form 10-
KSB,
filed for the year ended December 31, 2004.

(2)  Investments
Investments in available-for-sale securities are reported as a current
asset at their fair value in investments in securities.  Investments in
held-to-maturity securities are reported at their amortized cost in
investments securities.  Purchases and sales activity in certain bonds during
the first quarter of 2005, totaling approximately $1.3 million, requires
classification as held-for-sale investments. As a result, we included an
unrealized loss of $9,000, which amount is net of tax, in comprehensive
income
for the quarter due to recording such investments at their market value at
3/31/05.

(3)  Business Segment Information
The Company has three reportable segments: mercury emission controls (MEC),
flue gas conditioning (FGC), and combustion aids and consulting (CA).  All
assets are located in the US and are not evaluated by management on a segment
basis.  All significant customers are US companies.

Item 2.	 Management's Discussion and Analysis or Plan of Operation.
This Quarterly Report may contain forward-looking statements within the
meaning of Section 27A of the Securities Act of 1933 that involve risks and
uncertainties. The following discussion and analysis of the financial
condition and results of operations of the Company should be read in
conjunction with the audited consolidated financial statements and related
notes thereto included in the Company's Annual Report on Form 10-KSB for the
year ended December 31, 2004. Words or phrases such as "will," "hope,"
"expect," "intend," "plan" or similar expressions are generally intended to
identify forward-looking statements. Those statements involve risks and
uncertainties that could cause actual results to differ materially from the
results discussed herein. The principal risks and uncertainties that may
affect the Company's actual performance and results of operations include the
following: general economic conditions; adverse weather; changes in federal
income tax laws and federal funding for environmental technology/specialty
chemicals programs; governmental regulations; changes in governmental and
public policy; changes in economic conditions specific to one or more of the
Company's markets and businesses; competition; availability of raw materials;
and unexpected operations difficulties. Other risks and uncertainties may
also affect the outcome of the Company's actual performance and results of
operations. You are cautioned not to place undue reliance on the forward-
looking statements made in this Management's Discussion and Analysis of
Financial Condition and Results of Operations.


OVERVIEW
The Company provides environmental technologies and specialty chemicals to
the coal-burning electric utility industry. Revenues are generated through
(1) time and materials and fixed-price contracts for the emerging mercury
emission control (MEC) market, several of which are co-funded by government
(Department of Energy - DOE)and industry, (2) the sale of specialty chemicals
and services for flue gas conditioning (FGC), and (3) the sale of combustion
aid (CA) chemicals and services, primarily ADA-249 through a joint venture
with Arch Coal.

Mercury has been identified as a toxic substance and pursuant to a court
order the EPA issued regulations for its control in March 2005. Such
regulations are being contested by as many as nine different States and four
environmental groups.  The impact of those regulations on the future of our
business, and the long-term growth of the MEC market for the electric utility
industry will most likely be dependent on the final outcome of that court
action and how industry chooses to respond to those federal and other state
regulations, which are in various stages of enactment.  As many as 1,100
existing coal-fired boilers may be affected by such regulations, when they
are fully implemented.  Permitting of new coal-fired plants generally
requires them to meet more stringent requirements that likely include MEC.
For the near-term, our revenues from this market will be dependent on (i)
DOE- and industry-funded contracts mentioned above, (ii) mercury testing
services and (iii) equipment sales and commissions on sorbents sold to new
plants and existing plants affected by the implementation of enacted
regulations.  Although we expect this market to show steady growth over the
next several years, significant revenue growth is anticipated when federal
regulations impact a significant portion of existing boilers.

The market for our FGC chemicals and services is relatively flat and is
expected to only show modest growth, if any, in the near-term.  Margins on
these products are typically higher than what we recognize for our present
MEC sales and represent an important contribution to the overall
profitability of the Company.  In spite of several successful demonstrations,
market acceptance for our CA products has not grown as expected.
Commencement of ongoing sales to a significant future customer is
important, and if such occurs, is expected to help promote additional sales.

During the second quarter of 2004 the Company announced it signed a
commercial contract to supply and install a FGC system to improve capture of
flyash particles at a Midwestern coal-fired power plant. The plant has made
provisions to switch to coal from the Wyoming Powder River Basin (PRB).  The
contract called for the purchase and installation of the equipment for
approximately $300,000, which was installed and operational in December 2004,
and at such time began routine injection of the Company's proprietary
chemical. Based upon historical average usage of the chemical at existing
customers' plants, it is anticipated that future chemical purchases will
provide additional revenues of $500,000 - $700,000 per year.  During the
first quarter of 2005 chemical purchases totaling $253,000 were made by the
plant.

Liquidity and Capital Resources
The Company had a positive working capital of $4.9 million at 3/31/05. The
amount represents an increase of $1.6 million during the quarter. Of the
increase shown, $1.3 million is a result of reclassification of amounts
related to investments in bonds previously classified as held-to-maturity
investments noted above.  In addition to the working capital noted above, the
Company has investments in securities, accounted for as held to maturity
investments, that amount to approximately $4.5 million at 3/31/05. The
Company intends to retain these investments to demonstrate strength in its
financial position to support guarantees the Company expects to provide on
future sale of activated carbon systems.  Management believes that existing
and expected improving working capital, through continued and improved cash
flow from ongoing operations, will be sufficient to meet the anticipated
needs of the Company in 2005. However, there can be no assurances that the
positive cash flow that has been achieved will continue. The Company also has
a $250,000 line-of-credit arrangement with a bank to help with its working
capital needs. No amounts were outstanding under the line as of 3/31/05.

The Company's principal source of liquidity is its existing working capital
and operating cash flows as supplemented by its line-of-credit noted above.
The continuation of positive cash flow is somewhat dependent upon the
continuation of chemical sales and operations of the (FGC) units currently
in-place in Illinois, Louisiana and Iowa, each of which provide an average
monthly cash flow of approximately $20,000. Unsatisfactory results, which
could be caused by a combination or single factor such as changes in coal,
mechanical difficulties (whether in the FGC unit or otherwise), and/or
overall cost/benefit analysis, at any of those units may decrease or end the
sale of chemicals for such units. The Company is also performing services
under three DOE and industry co-funded contracts, which overall are expected
to produce an estimated $3.6 million in revenues in 2005. Of that amount
approximately 35% represents cost share amounts from industry partners, and
65% represents reimbursement from DOE for costs that pass through the
Company. Currently funding has been approved by the DOE for approximately
$15.8 million of its share of those contracts. If further funding were not
approved, the Company would decrease or cease activities on those contracts
and would expect to maintain a positive cash flow but at a reduced level.

Planned capital expenditures for ADA-ES to sustain and improve ongoing
operations for 2005 are estimated at $310,000. The Company expects to fund
these requirements out of existing working capital and cash flow from
operations.

The Company maintains a defined contribution and 401(k) plan covering all
eligible employees.  The Company matches up to 5% of salary amounts deferred
by employees in the Plan.  During the first quarter of 2005, the Company
recognized $21,000 of matching expense; this expense is expected to amount to
approximately $105,000 for the year.  In the past the Company has also made
discretionary contributions to the Plan and employees.  Based on results for
2004 such amount totaled approximately $160,000 and was paid in the form of
cash to all eligible employees in February 2005 with 50% of such amount being
made as a contribution to the Plan.  During the first quarter of 2005, the
Company accrued $22,000 for such payments based on results for 2005 through
the end of the 1st quarter.

The Company has recorded net deferred tax assets of $632,000 as of 3/31/05.
Based on existing R&D contracts supported by the DOE and industry and other
expectation of continuing work, the Company has determined that it is more
probable than not that those deferred tax assets will be realized in the
future.

Cash flow provided (used) in operations totaled $(321,000) for the first
quarter of 2005 compared to $151,000 for the same period in 2004. Cash flow
from operations in 2005 was lower than 2004 as the result of a significant
increase in accounts receivable and a decrease in accounts payable, both of
which reduced cash on hand as compared to 2004. Cash flow provided (used)
from operations in both periods resulted primarily from the operating income
(loss) plus non-cash charges for depreciation, amortization and expenses paid
with stock (in 2004 only) plus and minus other components of working capital.
Cash flow from net investing activities for the first quarter of 2005
includes a use for investments in securities of $(2,668,000), proceeds from
sales of securities of $2,628,000, and capital expenditures of $(28,000).
Cash flow from financing activities in 2005 consisted of payments on notes
payable of $(1,000), proceeds from the exercise of stock options of $272,000.
Cash flow from investing activities for the first quarter of 2004 includes a
use for capital expenditures of $(273,000). Cash flow from financing
activities in the first quarter of 2004 consisted of payments on notes
payable $(333,000), proceeds from note payable and proceeds from the exercise
of stock options of $329,000.

Results of Operations
Revenues totaled $2,172,000 for the first quarter of 2005 versus $1,540,000
for the same period in 2004. Revenues in 2005 increased $586,000 and $86,000
due to increased sales in MEC and FGC activities, respectively. The
significant increase in MEC revenues for the period is the result of
increased mercury measurement services, which commenced in the third quarter
of 2004 and which totaled $422,000 during the first quarter of 2005. FGC
revenues for the first quarter are $86,000 higher than in the same period in
2004 due to increased chemicals sales of the system installed in December
2004 noted above. CA revenues decreased by $40,000 in the first quarter of
2005 compared to the same period in 2004.  CA revenues for the first half of
2004 include sales to a customer who has not purchased on a routine basis
thus far in 2005.  In order for CA revenues to grow appreciably, we will need
to add additional customers.

MEC revenues are primarily a function of government and industry supported
field demonstrations of our mercury control technology, and other consulting
in mercury emission measurement.  The Company's government contracts are
subject to audit by the federal government, which could result in
adjustment(s) to previously recognized revenue. The Company believes,
however, it has complied with all the requirements of the contracts and
future adjustments, if any, will not be material.   Based on contracts in
hand and other anticipated work, total revenues for 2005 are anticipated to
grow by approximately 30% from the 2004 level. We have been hiring personnel
in response to the growth realized and adequate resources of skilled labor
appear to be available to cover the anticipated needs.

Cost of services increased by $419,000 in the first quarter of 2005, as
compared to the same period in 2004 as a result of the increased revenue
generating activities noted above. ADA-ES experienced gross margins in those
periods in 2005 and 2004 of 42% and 45%, respectively.  Management expects
the amount of time and materials related work for the near term to represent
an increasing source of revenues wherein the anticipated gross margins are
less than for our specialty chemical sales.  Gross margins for 2005 are
expected to decline somewhat from the levels achieved in 2004, both as a
result of an increasing proportion of time and materials work and the
Company's increasing its share of costs in the field demonstration projects
in which it has elected to participate.

Research and development expenses increased in the first quarter of 2005 by
$42,000 to $258,000 from the same period in 2004. The Company incurs R&D
expenses not only on direct activities it conducts but also by sharing a
portion of the costs in the government and industry programs in which it
participates.  Future consolidated research and development expenses, except
for those anticipated to be funded by the DOE contracts and others that may
be awarded, are expected to grow at about 10% per year for the next several
years.

General and administrative expenses increased by $96,000 to $552,000 in
the first quarter of 2005.  The increase in 2005 results primarily from
increases in staff, increased cost of governance and government compliance,
NASDAQ listing fees, and other general increases in costs.

The Company's interest expense totaled approximately $1,000 for the first
quarter of 2005 as compared to $14,000 for the same period in 2004.  The
Company repaid all of its significant term debt in early 2004 and as a
result, we expect future interest expense to be minimal.  Other income, net
shown for the first quarter of 2005 includes interest income from investments
and other miscellaneous receipts, net of related fees and costs.

Critical Accounting Policies and Estimates
Significant estimates are used in preparation of the financial statements and
include (1)the Company's allowance for doubtful accounts, which is based on
historical experience; (2)the Company's classification of investments in
held-to-maturity securities, which is based on management's intent and
ability to hold such securities to maturity and other factors; and (3)the
Company's percentage of completion method of accounting for significant long-
term contracts, which is based on estimates of the costs to complete such
contracts.

A significant amount of the Company's accounts receivable ($205,000 and
$338,000 at March 31, 2005 and 2004 respectively) is from the federal
government. Amounts invoiced for government contracts are subject to change
based on the results of future audits by the federal government. The Company
has not experienced significant adjustments in the past, and we do not expect
that a significant adjustment will be made in the future. The Company uses
its judgment to support the current fair value of goodwill and other
intangible assets of $2.1 million on the consolidated balance sheet. Although
in a prior year the Company had an independent valuation prepared, which
supports its recorded value and, management believes the fair value of other
recorded intangibles are not impaired, market demand for the Company's
product and services could change in the future requiring a write-down in
recorded values. As with all estimates, the amounts described above are
subject to change as additional information becomes available.

New Accounting Pronouncements
In December 2004, the FASB issued SFAS No. 123R, "Share-Based Payment". This
Statement is a revision of FASB Statement No. 123, "Accounting for Stock-
Based Compensation". This Statement supersedes APB Opinion No. 25,
"Accounting for Stock Issued to Employees", and its related implementation
guidance. SFAS No. 123R establishes standards for the accounting for
transactions in which an entity exchanges its equity instruments for goods or
services, or incurs liabilities in exchange for goods or services that are
based on the fair value of the entity's equity instruments or that may be
settled by the issuance of those equity instruments.  SFAS No. 123R focuses
primarily on accounting for transactions in which an entity obtains employee
services in share-based payment transactions and requires the Company to
measure and recognize costs of share-based payment transactions in the
financial statements.  Unless implementation is delayed by the U.S. Congress
or other authorities, the Company must implement SFAS No. 123R as of the
beginning of the first interim or annual reporting period that begins after
December 15, 2005.  The Company is evaluating the impact of SFAS No. 123R on
its financial statements and believes the impact may be material if equity
instruments are used as a significant means of compensation in the future.

Item 3.  CONTROLS AND PROCEDURES

Disclosure Controls and Procedures
The Company maintains disclosure controls and procedures designed to ensure
that it is able to collect the information it is required to disclose in the
reports it files with the Securities and Exchange Commission (SEC), and to
process, summarize and disclose this information within the time periods
specified in the rules of the SEC. Based on their evaluation of the Company's
disclosure controls and procedures which took place as of March 31, 2005, the
end of the period covered by this report, the Chief Executive and Financial
Officers believe that these controls and procedures are effective to ensure
that the Company is able to collect, process and disclose the information it
is required to disclose in the reports it files with the SEC within the
required time periods.

The Company also maintains a system of internal controls designed to provide
reasonable assurance that: transactions are executed in accordance with
management's general or specific authorization; transactions are recorded as
necessary (1) to permit preparation of financial statements in conformity
with generally accepted accounting principles, and (2) to maintain
accountability for assets; access to assets is permitted only in accordance
with management's general or specific authorization; and the recorded
accountability for assets is compared with the existing assets at reasonable
intervals and appropriate action is taken with respect to any differences.

During the company's last fiscal quarter, there have been no significant
changes in such controls or in other factors that have materially affected,
or is reasonably likely to materially affect, those controls.
