NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Basis of reporting for condensed consolidated financial statements and significant accounting policies.

The accompanying unaudited condensed consolidated financial statements of CECO Environmental Corp. and subsidiaries (the “Company”, “we”, “us”, or “our”) have been prepared in accordance with accounting principles generally accepted in the United States of America. In the opinion of management, the accompanying unaudited condensed consolidated financial statements of the Company contain all adjustments (consisting only of normal recurring accruals) necessary to present fairly the financial position as of September 30, 2006 and December 31, 2005 and the results of operations for the three-month and nine-month periods ended September 30, 2006 and 2005 and of cash flows for the nine-month periods ended September 30, 2006 and 2005. The results of operations for the three-month period and nine-month period ended September 30, 2006 are not necessarily indicative of the results to be expected for the full year.

These financial statements should be read in conjunction with the audited financial statements and notes thereto in our 2005 Annual Report on Form 10-K filed with the Securities and Exchange Commission.

Stock Based Compensation –

The Company adopted Statement of Financial Accounting Standards (SFAS) No. 123(R), “Share-Based Payment,” effective January 1, 2006. SFAS No. 123(R) requires public entities to measure the cost of employee services received in exchange for an award of equity instruments and recognize this cost over the period during which an employee is required to provide the services. The Company has adopted SFAS No. 123(R) using the “modified prospective application” as defined in the Statement, and therefore financial statements from periods ending prior to January 1, 2006 have not been restated. As a result of adopting SFAS No. 123(R) on January 1, 2006, the Company’s income before income taxes for the three months and nine months ended September 30, 2006 was $33,800 and $63,000 lower, respectively, and net income was $22,300 and $41,600 lower, respectively, than if it had continued to account for share-based compensation under APB No. 25. Basic and diluted earnings per share for the three months and nine months ended September 30, 2006 would have been unchanged if the Company had not adopted SFAS No. 123(R). See further discussion in Note 9.

Prior to January 1, 2006, the Company applied the provisions of Accounting Principles Board Opinion No. 25 (APB No. 25), “Accounting for Stock Issued to Employees.” Accordingly, no compensation expense was reflected in the financial statements as the exercise price of options granted to employees and non-employee directors equaled the fair market value of the Company’s common shares on the date of grant. The Company had adopted the disclosure-only provisions of SFAS No. 123, “Accounting for Stock Based Compensation.”

If the Company had adopted the expense recognition provisions of SFAS No. 123 prior to January 1, 2006, net income and earnings per share for the three month and nine month periods ended September 30, 2005 would have been as follows:

Certain amounts in the September 30, 2005 financial statements have been reclassified to conform to the September 30, 2006 presentation.

2. New Accounting Standards

In September 2006 the FASB issued SFAS No. 157, “Fair Value Measurements” (“SFAS No. 157”). SFAS No. 157 clarifies the principle that fair value should be based on the assumptions market participants would use when pricing an asset or liability and establishes a fair value hierarchy that prioritizes the information used to develop those assumptions. Under the standard, fair value measurements would be separately disclosed by level within the fair value hierarchy. SFAS 157 is effective for the Company's fiscal year beginning January 1, 2008, with early adoption permitted. The Company is in the process of evaluating SFAS No. 157.

In September 2006, the FASB issued Statement No. 158, “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans, an amendment of FASB Statements No. 87, 88, 106, and 132(R).” SFAS 158 requires companies to recognize the overfunded or underfunded status of a defined benefit post-retirement plan as an asset or liability in its balance sheet and to recognize changes in that funded status in the year in which the changes occur through comprehensive income.

The Company is required to initially recognize the funded status of its defined benefit postretirement plan and to provide the required disclosures as of the end of the fiscal year ending after December 15, 2006. The Company has not determined whether SFAS 158 will have a material effect on its condensed consolidated financial statements.

7. Debt

Total bank debt as of September 30, 2006 was $9.4 million and $6.8 million at December 31, 2005. Unused credit availability under our $13.0 million revolving credit facility at September 30, 2006 was $5.1 million. Availability is determined by a borrowing base formula contained in the credit agreement.

On December 28, 2005, CECO Environmental Corp. (the “Company”) entered into a $16.1 million credit facility (the “Facility”). The Facility was entered into among the Company, CECO Group, Inc., CECO Filters, Inc., New Busch Co., Inc., The Kirk & Blum Manufacturing Company, Kbd/Technic, Inc., CECOaire, Inc., CECO Abatement Systems, Inc. (all of which are direct or indirect subsidiaries of the Company and collectively with the Company, the “Borrowers”) and Fifth Third Bank, an Ohio banking corporation (“Fifth Third”).

On June 8, 2006, the Borrowers amended the Facility pursuant to a First Amendment to Credit Agreement (“Amendment”), an Amended and Restated Revolving Credit Promissory Note (“Revolving Note”), an Amended and Restated Term Promissory Note (“Term Note”), and a Joinder Agreement, all dated as of June 8, 2006. H.M. White, Inc., a wholly owned subsidiary of CECO Group, Inc., was added as a Borrower. In connection with the amendments to the Facility, the personal guaranty of Phillip DeZwirek was released pursuant to a Release of Guaranty dated June 8, 2006 (“Release”). The Amendment amended the Facility by, among other things (i) extending the maturity date of the Credit Agreement from January 31, 2007 to January 31, 2009, (ii) lowering the interest rate on the revolving loan and term loan from the prime rate plus 2.25% and the prime rate plus 2.0%, respectively, to either prime plus 0.5% or LIBOR plus 2.75%, at the option of the Borrowers, and (iii) establishing an incentive pricing grid pegged to performance.

8. Employee Benefit Plans

We sponsor a non-contributory defined benefit pension plan for certain union employees. The plan is funded in accordance with the funding requirements of the Employee Retirement Income Security Act of 1974. We also sponsor a post-retirement health care plan for office employees retiring before January 1, 1990. The plan allows retirees who have attained the age of 65 to elect the type of coverage desired. Retirement and health care plan expense is based on valuations performed by plan actuaries as of the beginning of each fiscal year. The components of the expense consisted of the following:

	Three Months Ended September 30,						Nine Months Ended September 30,

We previously disclosed in our financial statements for the year ended December 31, 2005 that we expected to make $483,000 in contributions to the Pension Plan during the year ending December 31, 2006. As of September 30, 2006, $374,000 has been contributed to the Pension Plan. The remaining 2006 contribution of $109,000 was paid in October 2006.

9. Equity compensation

On January 1, 2006, the Company adopted SFAS No. 123(R), “Share-Based Payment,” which requires the Company to measure the cost of employee services received in exchange for an award of equity instruments and to recognize this cost in the financial statements over the period during which an employee is required to provide services. The Company has adopted SFAS No. 123(R) using the “modified prospective application” as defined in the Statement, and therefore financial statements for periods ending prior to January 1, 2006 have not been restated. Prior to January 1, 2006, the Company had applied provisions of Accounting Principles Board Opinion No. 25, (“Accounting for Stock Issued to Employees”) and booked no compensation expense in the financial statements. The Company adopted the disclosure-only provisions of Statement of Financial Accounting Standards No. 123 (SFAS No. 123), “Accounting for Stock Based Compensation.”

Stock Options

The Company has an equity compensation plan that was approved by shareholders which covers all of its full-time employees, outside directors and advisors. The options granted or stock awards made pursuant to this plan are granted at fair market value or greater at date of grant or award and are issued as new shares by the Company’s transfer agent. Options granted to non-employee directors typically vest at 5,000 shares per year and options granted to employees typically become exercisable at 20% or 25% per year beginning one year after the date of grant. The Stock Option Committee may, at its discretion, establish other vesting periods when appropriate. The number of shares reserved for issuance is 1.5 million, of which 1.1 million shares were available for future grant or award as of September 30, 2006. This plan allows for the grant of incentive stock options and non-qualified stock options. As of September 30, 2006, a total of 282,605 options for common shares were outstanding and of these, a total of 90,105 options for common shares were vested and exercisable.

SFAS No. 123 was effective for the Company through December 31, 2005 and required, at a minimum, pro forma disclosures of expense for stock-based awards based on their fair values. See Note 1 for this information. The fair value of each option on the date of grant was estimated using the Black-Scholes option pricing model.

SFAS No. 123(R) requires stock option expense to be recorded on the financial statements for all reporting periods beginning after January 1, 2006. Accordingly, expenses of $33,800 and $63,000 respectively were recorded in the three months and nine months ended September 30, 2006. No similar expense was recorded in fiscal 2005. No equity compensation expense has been capitalized in inventory or fixed assets.

Awards granted prior to January 1, 2006:

Prior to January 1, 2006, the Company applied the provisions of APB No. 25 and no compensation expense was recorded in the financial statements. The Company had adopted the disclosure-only provisions of SFAS 123, Accounting for Stock-Based Compensation.

Compensation cost for the outstanding stock options as of January 1, 2006, for which the requisite service has not been rendered, will be recognized over their remaining vesting periods. The compensation cost for these outstanding options will be based upon their originally calculated fair values as used in pro forma disclosures under SFAS 123, except that the Company will discontinue its previous method of recognizing forfeitures only as they occur. As of January 1, 2006, the Company has estimated the number of these outstanding options which will be forfeited prior to vesting and has accordingly adjusted compensation expense for these options going forward.

As no compensation expense has previously been recorded in the Company’s financial statements for these outstanding options, no cumulative effect of a change in accounting principle is required as of January 1, 2006.

Awards granted after adoption of SFAS 123(R):

For awards granted during the nine months ended September 30, 2006, the Company utilized the Black-Scholes option pricing model to determine grant-date fair value, using the following assumptions:

• Expected Volatility of 60% was used based upon the historical volatility of the Company’s stock price for a period of time commensurate with the expected terms of the options. The frequency of price observations was based on weekly values.

• The Expected Terms of 6.5 years for options that vest in 3 years and 7.5 years for options that vest in 5 years for “plain vanilla” were calculated using the simplified method as permitted under the guidelines of SAB 107.

• The Risk-Free Interest Rates of 5.16% for options that vest in 3 years and 5.19% for options that vest in 5 years were based upon the implied yields currently available on U.S. Treasury zero-coupon issues with a remaining term equal to the Expected Term.

• No assumptions were made for Expected Dividends as the Company has not historically paid dividends. This will be re-evaluated if and when dividends are expected to be paid.

The fair value of the granted options is recorded as compensation expense on a straight-line basis over the vesting period of the option. The amount of compensation cost recognized at any date (for graded-vesting options) is at least equal to the portion of the grant-date value of the award that is vested at that date. As required under SFAS 123(R), the Company estimated that 7.0 % of the options granted in the nine months ended September 30, 2006 will be forfeited and has adjusted compensation expense accordingly. This estimate will be reviewed periodically and updated as necessary.

The intrinsic value of these exercised options totaled $118,000 and $610,000 for the three months and nine months ended September 30, 2006 respectively.

The Company also received $361,000 of cash from 101,000 warrants exercised during the three months ended September 30, 2006. The intrinsic value of these warrants was $455,000. For the nine months ended September 30, 2006, the Company has received $3.1 million in cash for the exercise of 1,348,567 warrants. The intrinsic value of these warrants totals $6.7 million. The company has a net operating loss carryforward and, as a result, the tax benefit and credit to additional paid-in capital for the excess deduction will not be recognized until that future deduction reduces current taxes payable.

Due to improved domestic economic conditions, a strong demand for pollution control systems and ongoing activity in the ethanol industry, our sales have increased significantly over last year. Consolidated net sales for the third quarter were $37.7 million, an increase of $14.3 million or 61% compared to the same quarter in 2005. Consolidated net sales for the first nine months of 2006 were $93.9 million, an increase of $35.3 million or 60% compared to the same period in 2005. For the quarter and the first nine months, we reported significant sales increases from our construction activities as well as higher revenues from equipment sales and slightly increased revenues from parts sales.

New orders booked were $43.9 million during the third quarter of 2006 and $114.8 million for the first nine months of 2006, as compared to $19.3 million during the third quarter of 2005 and $60 million in the first nine months of 2005.

Third quarter 2006 gross profit increased $1.6 million or 35.8 % to $6.1 million compared to a gross profit of $4.5 million during the same period in 2005. Gross profit for the quarter as a percent of sales decreased by 3.0 percentage points to 16.3% from 19.3% due to changes in product mix and one underperforming large project. For the first nine months of 2006, gross profit increased $4.9 million or 44.8% to $15.9 million compared to $11.0 million for the same period in 2005. Gross profit as a percent of sales decreased by 1.8 percentage points to 16.9% from 18.7% in 2006. This decrease was also due to changes in product mix and an underperforming large project.

Selling and administrative expenses increased by $1.2 million or 40.7% to $4.2 million during the third quarter of 2006 from $3.0 million in the same period of 2005. The increase was due to the addition of H.M. White selling and administrative expenses, increases in incentive compensation accruals relating to improved financial performance and increased selling and administrative wages. Selling and administrative expenses as a percent of sales decreased by 1.6 percentage points from 12.7% in the 2005 quarter to 11.1% in the 2006 quarter. Selling and administrative expenses increased by $2.8 million or 32.6% to $11.4 million during the first nine months of 2006 from $8.6 million in the same period of 2005.

This nine month increase was due to the same factors previously discussed. Selling and administrative expenses as a percent of sales decreased by 2.6 percentage points from 14.7% in the 2005 nine month period compared to 12.1% for the nine months ended September 30, 2006.

Depreciation and amortization remained constant at $293,000 during the third quarter of 2006 and increased slightly in the first nine months from $876,000 in 2005 to $878,000 in 2006.

Operating income increased by approximately $400,000 or 32.4% to $1.7 million in the third quarter of 2006 compared to operating income of $1.3 million during the same quarter of 2005. The impact of significantly increased revenues and lower margins due to changing product mix in the third quarter, as well as increases in selling and administrative expenses, were the primary factors for the increase in operating income. Operating income for the first nine months of 2006 increased by $2.1 million or 142% to $3.6 million compared to operating income of $1.5 million during the same period of 2005. This nine month increase was also due to significantly increased revenues offset by lower margins and increases in selling and administrative expenses.

Other income was $409,000 in the third quarter of 2006 compared to other expense of $273,000 in the third quarter of 2005. $432,000 of this third quarter 2006 income was the result of the exercise of 100,600 warrants issued in December 2001 less $23,000 of expense created by an increase in the Company’s stock price which increased the carrying value of the remaining warrants issued in December 2001. Other income for the nine months ended September 30, 2006 was $703,000 compared to other expense of $197,000 in 2005. $727,000 of this nine month 2006 income was the result of the exercise of 348,567 warrants issued in December 2001 less $64,000 of expense created by an increase in the Company’s stock price which increased the carrying value of the remaining unexercised warrants which were issued in December 2001.

Interest expense decreased by $134,000 to $460,000 from $594,000 during the third quarter of 2006. Interest expense decreased by $200,000 to $1.6 million from $1.8 million during the first nine months of 2006. The decrease in both periods was due to lower debt balances and lower contractual interest rates partially offset by higher market interest rates.

Federal and state income tax provision was $546,000 during the third quarter of 2006 compared to $35,000 during the third quarter of 2005. Federal and state income tax expense was $853,000 for the first nine months of 2006 compared to a tax benefit of $482,000 in 2005.

The federal and state income tax expense for the three months ended September 30, 2006 was 34% of income from operations before income taxes. This quarterly expense reflects an adjustment to increase the estimated effective tax rate from 27% to 31% for 2006, due to a higher estimated taxable income. Our effective income tax rate is affected by certain permanent differences including non-deductible interest expense and non-taxable income from the exercise of warrants.

Net income for the quarter ended September 30, 2006 was $1.1 million compared with net income of $355,000 for the same period in 2005. Net income for the nine months ended September 30, 2006 was $1.9 million compared with a net loss of $42,000 for the same period in 2005. This increase in net income for the quarter and for the nine months ended September 30, 2006 was the result of the previously discussed factors.

Backlog

Our backlog consists of orders we have received for products and services we expect to ship and deliver within the next 12 months. There can be no assurances that backlog will be replicated, increased or translated into higher revenues in the future.

Our backlog, as of September 30, 2006 was $50.1 million compared to $28.9 million as of December 31, 2005. The success of our business depends on a multitude of factors related to our backlog and the orders secured during the subsequent period(s). Certain contracts are highly dependent on the work of contractors and other subcontractors participating in a project, over which we have no or limited control, and their performance on such project could have an adverse effect on the profitability of our contracts. Delays resulting from these contractors and subcontractors, changes in the scope of the project, weather, and labor availability also can have an effect on a contract’s profitability.

Financial Condition, Liquidity and Capital Resources

Our principal sources of liquidity are cash flow from operations and available borrowings under our revolving credit facility. Our principal uses of cash are operating costs, debt service, payment of interest on our outstanding senior debt, capital expenditures, working capital and other general corporate requirements.

At September 30, 2006 and December 31, 2005, cash and cash equivalents totaled $338,000 and $310,000 respectively. Generally, we do not carry significant cash and cash equivalent balances because excess amounts are used to pay down our revolving credit facility.

Total bank debt as of September 30, 2006 was $9.4 million and $6.8 million at December 31, 2005. Unused credit availability under our $13.0 million revolving line of credit at September 30, 2006 was $5.1 million.

On December 28, 2005, the Company entered into a $16.1 million credit facility (the "Facility"). The Facility was entered into among the Company, CECO Group, Inc., CECO Filters, Inc., New Busch Co., Inc., The Kirk & Blum Manufacturing Company (“K&B”), Kbd/Technic, Inc., CECOaire, Inc., CECO Abatement Systems, Inc. (all of which are direct or indirect subsidiaries of the Company and collectively with the Company, the "Borrowers") and Fifth Third Bank, an Ohio banking corporation ("Fifth Third"). On June 8, 2006, the Borrowers amended the Facility pursuant to a First Amendment to Credit Agreement ("Amendment"), an Amended and Restated Revolving Credit Promissory Note ("Revolving Note"), an Amended and Restated Term Promissory Note ("Term Note"), and a Joinder Agreement, all dated as of June 8, 2006. H.M. White, Inc., a wholly owned subsidiary of CECO Group, Inc., was added as a Borrower. In connection with the amendments to the Facility, the personal guaranty of Phillip DeZwirek was released pursuant to a Release of Guaranty dated June 8, 2006 ("Release"). The Amendment amended the Facility by, among other things (i) extending the maturity date of the Credit Agreement from January 31, 2007 to January 31, 2009, (ii) lowering the interest rate on the revolving loan and term loan from the prime rate plus 2.25% and the prime rate plus 2.0%, respectively, to either prime plus 0.5% or LIBOR plus 2.75%, at the option of the Borrowers, and (iii) establishing an incentive pricing grid pegged to performance.

The subordinated debt is reported as current portion of debt in the balance sheet at September 30, 2006 since the notes mature in April 2007.

In June 2005, we accepted an offer to sell our Cincinnati property with a contemplated closing date of July 15, 2005 subject to various contingencies. The purchase agreement called for 10.7 acres of real estate and improvements to be divided into two parcels, with the first parcel scheduled to close on or before July 15, 2005, for a purchase price of $6.9 million and the second parcel was scheduled to close on or before April 1, 2006, for a purchase price of $1.1 million. In July, August and September of 2005, the buyer exercised each of its three, thirty day options and extended the closing to October 31, 2005. In connection with these extensions, the buyer has paid nonrefundable extension fees of $175,000, which have been recorded in other liabilities on the accompanying condensed, consolidated balance sheet.

On October 20, 2005, due to time constraints and other pending projects, the buyer chose to assign the agreement, with our consent, to a third party that had indicated its desire to purchase the Cincinnati properties. Therefore, the agreement was amended and the buyer transferred all of its right, title and interest under the agreement to Millworks Town Center, LLC. In addition, under the most recent amendment to this agreement, the closing of Parcel A has been extended until December 11, 2006.

The refundable deposit of $200,000 that was held in escrow was returned to the buyer by the title agent. The extension fees paid by the buyer, totaling $175,000, were retained by us in accordance with the terms of the original agreement. The closing of the acquisition is still subject to various customary closing conditions.

Overview of Cash Flows and Liquidity

	For the nine months ended September 30,
($’s in thousands)	2006			2005
Total operating cash flow (used in) provided by	$	(3,273	)	$	545
Net cash used in investing activities		(618	)		(452	)
Net cash provided by financing activities		3,919			101
Net increase	$	28		$	194

Cash used by operating activities was $3.3 million in 2006 compared to cash provided in 2005 of $545,000. Cash used in operating activities for the first nine months of 2006 was the result of an increase in accounts receivable of $9.5 million, an increase of $7.0 million in costs in excess of billings and estimated earnings on uncompleted contracts and a decrease in detachable stock warrants of $735,000, partially offset by net income of $1.9 million, increases in accounts payable and accrued expenses of $4.3 million and an increase in billings in excess of cost and estimated earnings of $7.0 million. Other changes in working capital items provided cash of $586,000. Our net investment in working capital (excluding cash and cash equivalents and current portion of debt) at September 30, 2006 and December 31, 2005 was $11.4 million and $4.9 million, respectively.

Net cash used in investing activities related to the acquisition of capital expenditures for property and equipment was $618,000 for the first nine months of 2006 compared with $452,000 for the same period in 2005. We are managing our capital expenditure spending in light of the current level of sales. As sales continue to increase in 2006, we anticipate increased capital spending. Additionally, capital expenditures may be incurred depending on the ultimate disposition of our Cincinnati property.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURE ABOUT MARKET RISK

Risk Management Activities

In the normal course of business, we are exposed to market risk including changes in interest and raw material commodity prices. We may use derivative instruments to manage our interest rate exposures. We do not use derivative instruments for speculative or trading purposes. Generally, we enter into hedging relationships such that changes in the fair values of cash flows of items and transactions being hedged are expected to be offset by corresponding changes in the values of the derivatives.

Interest Rate Management

We may use interest rate swap contracts to adjust the proportion of our total debt that is subject to variable interest rates.

The remaining amount of loans outstanding under the Credit Agreement bear interest at the floating rates as described in Note 7 to the consolidated statements contained in the Company’s 2005 Annual Report on Form 10-K filed with the Securities and Exchange Commission.

Credit Risk

As part of our ongoing control procedures, we monitor concentrations of credit risk associated with financial institutions with which we conduct business. We also monitor the creditworthiness of our customers to which we grant credit terms in the normal course of business. Concentrations of credit associated with these trade receivables are considered minimal due to our geographically diverse customer base. Bad debts have not been significant. We do not normally require collateral or other security to support credit sales.

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e)) under the Securities and Exchange Act of 1934 (the “Exchange Act”) designed to ensure that information required to be disclosed in reports filed under the Securities Exchange Act of 1934, as amended, is recorded, processed, summarized and reported within the specified time periods. Our Chief Executive Officer and Chief Financial Officer evaluated, with the participation of our management, the effectiveness of our disclosure controls and procedures as of September 30, 2006. Based on the evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures are effective. There were no significant changes in our disclosure controls or in other factors that could significantly affect our disclosure controls and procedures subsequent to the evaluation.

Internal Controls Over Financial Reporting

There were no significant changes in our internal controls over financial reporting that occurred during our most recent fiscal quarter that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
