If answer is no, identify report(s). [ X ] Yes [ ]No (3) Is it anticipated that any significant change in results of operations from the corresponding period for the last fiscal year will be reflected by the earnings statements to be included in the subject report or portion thereof [ X ] Yes [ ]No If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made. Revenues from continuing operations for the fiscal year ending December 31, 2006 will show a significant increase from revenues reported for the 2005 fiscal year. We estimate that net sales revenues will total approximately $15,488,000 for 2006 versus $11,028,000 in 2005, representing an increase of approximately 40%. The net sales increase was a result of an increase in revenue in our Mercury Emissions Control (MEC) segment for 2006 of approximately $4,823,000 (55%), with a concurrent decrease in revenue for our Flue Gas Conditioning (FGC) and Other Activities segment by ($363,000) (16%). Net income from continuing operations will show a decrease of approximately $286,000 for 2006 over 2005, to approximately $377,000 from $663,000. This was the result of an increase in cost of revenues for the MEC segment of approximately $2,704,000 in 2006, as compared to the same period in 2005, primarily as a result of the increased revenue generating activities noted above, and an increase on the cost of revenues for the FGC and other segment of $137,000 in 2006, as compared to 2005 as a result of increased costs for development projects included in this segment. Other significant contributors to the decrease in net income from continuing operations were an increase in general and administrative expenses by $1,668,000 or 67% to $4,170,000 in 2006 over 2005, an increase in research and development expenses by $487,000 or 50% in 2006 as compared to 2005. Finally, although not included in income from continuing operations, we incurred $411,000 of expenses related to our M&A activities in 2006, which was offset by interest and other income of $909,000 in 2006, as compared to $357,000 for 2005, which was due to an increase in invested balances and increasing interest rates. Net income per common share basic and diluted is expected to be $0.07 in 2006 compared to $0.13 in 2005. Net income per diluted share was calculated on 12% more shares outstanding due to a 790,000-share private equity placement commenced in October 2005 for which the shares were not issued until 2006. The following sets forth a summary in tabular format of our anticipated income statement data for 2006 as compared to 2005: Year Ended December 31, ---------------------- 2006 2005 -------- --------- REVENUE: Mercury emission control $ 13,607 $ 8,784 Flue gas conditioning and other 1,881 2,244 -------- -------- Total net revenues 15,488 11,028 COST OF REVENUES Mercury emission control 8,426 5,722 Flue gas conditioning and other 1,156 1,019 -------- -------- Total cost of revenues 9,582 6,741 -------- -------- GROSS MARGIN 5,906 4,287 OTHER COSTS AND EXPENSES: General and administrative 4,170 2,502 Research and development 1,464 977 Depreciation and amortization 284 157 -------- -------- Total other costs and expenses 5,918 3,636 OPERATING INCOME (LOSS) (12) 651 OTHER INCOME (EXPENSE): Other expense and interest (412) (9) Interest and other income 909 357 -------- -------- Total other income 497 348 -------- -------- INCOME BEFORE TAX 485 999 PROVISION FOR TAX EXPENSE (108) (336) -------- -------- NET INCOME 377 663 UNREALIZED GAINS AND (LOSSES) ON CERTAIN INVESTMENTS IN DEBT AND EQUITY SECURITIES, NET OF TAX 134 (1) -------- -------- COMPREHENSIVE INCOME $ 511 $ 662 ======== ======== NET INCOME PER COMMON SHARE - BASIC AND DILUTED $ .07 $ .13 ======== ======== WEIGHTED AVERAGE COMMON SHARES OUTSTANDING 5,624 4,966 ======== ======== WEIGHTED AVERAGE DILUTED COMMON SHARES OUTSTANDING 5,729 5,137 ======== ======== -------------------------------------------------------------------------------- ADA-ES, Inc. ------------------------------------------ (Name of Registrant as Specified in Charter) has caused this notification to be signed on its behalf by the undersigned hereunto duly authorized.
