ITEM 7. FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS (c) Exhibits Exhibit No. Description of Exhibit 99.1 Press Release dated August 10, 2004 ITEM 9. REGULATION FD DISCLOSURE Today, August 10, 2004, the Registrant is issuing a press release announcing its fiscal 2004 third quarter and first nine months financial and operating results. This press release is furnished herewith as Exhibit 99.1 and will be posted on the Registrant's website located at http://www.escotechnologies.com. It can be viewed through the Investor Relations page of the website under the tab "Press Releases", although the Registrant reserves the right to discontinue that availability at any time. In addition, the Registrant announced in a press release issued on July 16, 2004 that a webcast of a fiscal third quarter conference call would be held on August 10, 2004 at 9:30 am, central time, and that the related press release would be available on that date. ITEM 12. RESULTS OF OPERATIONS AND FINANCIAL CONDITION Operations and Financial Information Furnished Today, the Registrant is issuing a press release (Exhibit 99.1 to this report) announcing its fiscal 2004 third quarter and first nine months financial and operating results. See Item 9, Regulation FD Disclosure, above. Non-GAAP Financial Measures The press release furnished herewith contains financial measures and financial terms not calculated in accordance with generally accepted accounting principles in the United States of America ("GAAP") in order to provide investors and management with an alternative method for assessing the Registrant's operating results in a manner that is focused on the performance of the Registrant's ongoing operations. The Registrant has provided definitions below for the non-GAAP financial measures utilized in the press release, together with an explanation of why management uses these measures, and why management believes that these non-GAAP financial measures are useful to investors. The press release uses the non-GAAP financial measures of "operational" net earnings, earnings per share and results of operations and also of "EBIT from continuing operations," "EBIT margin", "free cash flow from continuing operations" and Filtration segment "operational" EBIT. The Registrant defines "operational" net earnings, earnings per share, and results of operations as net earnings, earnings per share, and results of operations in accordance with GAAP, except for the exclusion of (i) exit costs and severance charges related to the shutdown of the Filtration segment Puerto Rico facility, (ii) asset impairment charges related to the Filtration segment Puerto Rico facility and Test segment U.K. facility, (iii) severance charges related to the Test segment U.K. facility, (iv) gain from settlement of patent litigation related to the Filtration segment, (v) costs resulting from the Management Transition Agreement between the Registrant and its former Chairman and (vi) the charge resulting from an equipment lease termination related to the Whatman Hemasure contract dispute. The Registrant defines "operational" EBIT margin as EBIT margin (defined below) with the foregoing exclusions. The Registrant's management uses these "operational" results in evaluating the measures of continuing operations of the Registrant and believes that this information provides investors with additional insight into the period over period financial performance of the Registrant.

The Registrant defines "EBIT from continuing operations" as earnings before interest and taxes. The Registrant defines "EBIT margin" as EBIT from continuing operations as a percent of net sales. The Registrant's management evaluates the performance of its operating segments based on EBIT from continuing operations and EBIT margin, and believes that EBIT from continuing operations and EBIT margin are useful to investors to demonstrate the operational profitability of the Registrant's business segments by excluding interest and taxes, which are generally accounted for across the entire Registrant on a consolidated basis. EBIT from continuing operations is also one of the measures used by management in determining resource allocations within the Registrant and incentive compensation. The Registrant defines "Free cash flow from continuing operations" as "Net cash provided by operating activities-continuing operations" less "Capital expenditures-continuing operations". The Registrant's management believes that free cash flow from continuing operations is useful to investors and management as a supplemental financial measurement in the evaluation of the Registrant's business and believes that free cash flow may provide additional information with respect to the Registrant's ability to meet its future debt service, capital expenditures and working capital requirements. Free cash flow can also be reinvested in the Registrant for future growth. The Registrant defines Filtration segment "operational" EBIT as segment EBIT, excluding the following: (i) exit costs, severance charges and asset impairment charges related to the shutdown of the Puerto Rico facility, (ii) the gain from settlement of patent litigation, and (iii) the charge resulting from an equipment lease termination related to the Whatman Hemasure contract dispute. The presentation of the information described above is intended to supplement investors' understanding of the Registrant's operating performance. The Registrant's non-GAAP financial measures may not be comparable to other companies' non-GAAP financial performance measures. Furthermore, these measures are not intended to replace net earnings, cash flows, financial position, or comprehensive income (loss), as determined in accordance with GAAP. Other Matters The information contained in this report, including Exhibit 99.1, shall not be deemed to be "filed" for the purposes of Section 18 of the Securities Exchange Act of 1934 as amended ("Exchange Act") or otherwise subject to the liabilities of that section, unless the Registrant specifically incorporates it by reference in a document filed under the Securities Act of 1933 as amended or the Exchange Act. SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.

Add One Results of Operations (in millions, except EPS) Sales and net earnings for the fiscal 2004 and 2003 third quarter and nine month year-to-date periods ended June 30 are noted below: 3rd Qtr. - FY 2004 Sales Net Earnings Diluted EPS ------------------ ----- ------------ ----------- GAAP $107.9M $12.0M $0.90 Operational $107.9M $11.2M $0.84 3rd Qtr. - FY 2003 Sales Net Earnings Diluted EPS ------------------ ----- ------------ ----------- GAAP $90.8M $4.2M $0.32 Operational $90.8M $6.7M $0.51 9 Months YTD - FY 2004 Sales Net Earnings Diluted EPS ---------------------- ----- ------------ ----------- GAAP $306.5M $23.6M $1.77 Operational $306.5M $26.4M $1.98 9 Months YTD - FY 2003 Sales Net Earnings Diluted EPS ---------------------- ----- ------------ ----------- GAAP $291.1M $16.3M $1.25 Operational $291.1M $24.1M $1.84 Sales ----- Fiscal 2004 third quarter consolidated sales of $107.9 million were $17.1 million, or 19 percent higher than fiscal 2003 third quarter sales. Year-to-date sales of $306.5 million in fiscal 2004 increased $15.4 million, or 5 percent versus the similar period in fiscal 2003. Favorable foreign currency values resulted in approximately $1 million and $5 million of the sales increases realized in the fiscal 2004 third quarter and year-to-date, respectively, as compared to prior year. - more -

Add Two On a segment basis for the fiscal 2004 third quarter, Communications sales increased 31 percent, Test sales increased 29 percent and Filtration sales increased 6 percent, as compared to the prior year third quarter. Year-to-date, fiscal 2004 Communications sales decreased 7 percent, Test sales increased 26 percent and Filtration sales increased 5 percent as compared to the first nine months of fiscal 2003. Communications segment sales increased in the third quarter as a result of significantly higher shipments of Automatic Meter Reading (AMR) equipment to electric utility cooperative customers (COOP), as well as sales to two new investor-owned utility customers (IOUs), Bangor Hydro-Electric Company and Idaho Power Company. Sales to PPL Electric Utilities Corporation (PPL) decreased approximately $12 million in the current year's third quarter compared to the third quarter of fiscal 2003. Sales to PPL were $0.6 million and $20.6 million in the fiscal 2004 third quarter and nine months, respectively, compared to $12.5 million and $50.4 million in the prior year third quarter and nine months, respectively. DCSI's sales to COOP and other customers increased 58 percent during the first nine months of fiscal 2004 to $76.5 million, from $48.3 million in the comparable period of fiscal 2003. Year-to-date sales decreased approximately $1.5 million at DCSI compared to prior year, primarily as a result of $30 million less sales to PPL in the current year as the contract nears completion. Sales decreased approximately $5.3 million year-to-date at Comtrak (SecurVision product) as a result of a delay in deliveries due to a significant customer requesting a modification of the operating system to provide enhanced "virus" protection. Deliveries of SecurVision products to this customer are expected to resume during the fourth quarter of fiscal 2004. Filtration segment sales increased in fiscal 2004 primarily as a result of higher defense shipments at VACCO; additional sales of commercial and automotive products at Filtertek; and, in the year-to-date period, favorable foreign currency exchange rates related to Filtertek's European operations. - more -

Add Three The Test segment sales increased significantly in the current quarter and year-to-date periods as a result of two significant test chamber installations in Europe and increased volume from the Company's Asian operations. Also, fiscal 2004 included the results of the acoustics business for nine months versus six months in the prior year. Earnings Before Interest and Taxes (EBIT) - ----------------------------------------- EBIT from continuing operations for the three and nine month periods ended June 30, 2004 and 2003 was affected by the Puerto Rican facility exit and move costs (fiscal 2004 and 2003), the patent litigation gain (fiscal 2003) and the MTA and MSA costs (fiscal 2003). In fiscal 2004, the pretax charges in continuing operations related to Puerto Rico were zero for the third quarter and $1.3 million year-to-date. In fiscal 2003, the pretax charges in continuing operations related to the above items were $3.0 million and $5.9 million for the third quarter and year-to-date periods, respectively. These items are included in "Earnings before income taxes" in the Exhibits attached to this release. On a segment basis, the following items impacted EBIT from continuing operations as a percent of sales ("EBIT margin") during the third quarter and nine months of fiscal 2004. In the Communications segment, EBIT margin is higher than prior year due to the increased sales volume, favorable sales mix resulting from additional sales to the COOP market, and cost reductions realized on certain components. In addition, the fiscal 2003 third quarter sales mix included a significant amount of lower margin commercial and industrial (C&I) meter modules. In the Filtration segment, EBIT margin improved in the third quarter of fiscal 2004 primarily due to higher defense sales at VACCO. The fiscal 2003 third quarter and year-to-date amounts were impacted by the Puerto Rico exit and move costs and the patent litigation gain. - more -

Add Four Year-to-date in fiscal 2004, EBIT margin in the Filtration segment was impacted by the exit and move costs incurred and the inefficiencies being absorbed at Filtertek during the first six months of fiscal 2004 as a result of operating in both the Puerto Rico and Juarez facilities. The move out of Puerto Rico was completed in mid-March 2004, and the facility is still being actively marketed for sale. Filtration EBIT was also negatively impacted by the lower sales of commercial aerospace products. In the Test segment, EBIT margin improved in the current fiscal year as a result of the significantly higher sales volume recognized in fiscal 2004. The fiscal 2003 amounts included costs associated with the U.K. facility consolidation mentioned in earlier releases. New Orders and Cash Flow - ------------------------ New orders received during fiscal 2004 were $96.6 million and $291.7 million for the third quarter and nine-month period, resulting in a backlog at June 30, 2004 of $248.2 million. New orders received during the first nine months of fiscal 2004 in Filtration, Communications and Test were $126.6 million, $89.2 million, and $75.9 million, respectively. During the first nine months of fiscal 2004, the Company generated $22.9 million of free cash flow from continuing operations. Discontinued operations used $4.1 million of free cash flow. Free cash flow from continuing operations is defined as "Net Cash Provided by Operating Activities - Continuing Operations" less "Capital Expenditures - Continuing Operations." For a reconciliation of free cash flow, see the Exhibits attached to this release. Stock Repurchase Program On August 4, 2004, the Company's Board of Directors approved an extension of the previously authorized stock repurchase program, whereby the Company can currently purchase up to 1.1 million of its outstanding shares through the period ending September 30, 2006. The original authorization was for 1.3 million shares, and the Company has repurchased approximately 200,00 shares under this program since the original authorization in fiscal 2001. - more

Add Five MicroSep Divestiture - -------------------- During the fiscal 2004 third quarter, the Company sold its MicroSep businesses in two separate transactions for approximately $23 million in cash. The transactions were detailed in earlier releases. Chairman's Commentary - --------------------- Victor L. Richey, Chairman and Chief Executive Officer, commented, "I am particularly gratified by the strength of our third quarter results in that they are the product of both the repositioning plan we initiated a year ago, and the ongoing focus on our cost and competitive position across all of our businesses. "While throughout the year we had consistently expected a strong second half, our current expectations, as outlined in the Business Outlook Section of this release, are considerably better than our previous view. The incremental improvement is for the most part driven by the Communications segment. Perhaps more important though is the fact that we expect all three of our segments to make meaningful contributions throughout the second half of fiscal 2004. "In addition to completing the divestiture of the MicroSep businesses, we accomplished a number of other things in the third quarter which were noteworthy. "In the Test Segment, we were selected by Boeing to provide a $21 million aircraft chamber complex to the Agency for Defense Development of South Korea as a part of Boeing's F-15K offset program. Although we were notified in June of our selection, the contract was only recently negotiated and as such, the order will be reflected in our fourth quarter backlog. "In Communications, we expanded our presence in the IOU market with the award received in April 2004 from Bangor Hydro-Electric Company. We also positioned ourselves for - more -

Add Six further differentiation in the AMR market through the acquisition of pre-payment technology from CIC Global LLC. Over the next 12 months we intend to integrate the acquired capability into our TWACS offering." Mr. Richey concluded, "I particularly appreciate both the support and guidance we received from our Board throughout the formulation and execution of our repositioning plan. I also greatly appreciate the support and patience of our shareholders. Having essentially completed the actions we initiated a year ago, the challenge ahead is to grow the business from what I believe is a strong foundation. Although timing can be a challenge with new product undertakings, acquisitions and major new programs, I believe we have both the resources and opportunities to succeed over the long term." Fiscal 2004 Business Outlook - ---------------------------- Statements contained in the preceding and following paragraphs are based on current expectations. Statements that are not strictly historical are forward-looking, and actual results may differ materially. Fourth Quarter Revenue and EBIT - ------------------------------- Management expects the aggregate revenues for the fourth quarter of fiscal 2004 to be consistent with the third quarter of fiscal 2004. On a segment basis, the fourth quarter revenue expectations relative to the third quarter of fiscal 2004, are flat for Communications, modestly lower in Filtration due to the August European holiday plant shutdown, and modestly higher in Test. The current expectations for the fourth quarter fiscal 2004 EBIT margins by segment compared to the fiscal 2004 third quarter EBIT margins are flat for Communications, an - more -

Add Seven improvement of 1 to 2 percent in Filtration primarily resulting from further benefits related to the closure of the Puerto Rico facility, and 1 to 2 percent lower margins in Test resulting from the sales mix. Earnings Per Share (GAAP and Operational) - ----------------------------------------- Management anticipates both GAAP and Operational earnings per share (EPS) for the fourth quarter of fiscal 2004 will be between $0.81 and $0.86 per share. The resulting fiscal year 2004 EPS from continuing operations on a GAAP and Operational basis is expected to be $2.72 to $2.77 per share, and $2.80 to $2.85 per share, respectively. The previous range of EPS guidance from continuing operations was $2.42 to $2.52 per share on a GAAP basis, and $2.50 to $2.60 per share on an Operational basis.

Add Eight Forward-Looking Statements - -------------------------- Statements in this press release regarding the results and timing of real estate sales, the level of contributions from each segment, the success and timing of technology integration efforts, the ability to differentiate the Company in the AMR markets, future fiscal 2004 revenues, EBIT, EPS and earnings, long term success of the Company, and other written or oral statements which are not strictly historical are "forward-looking" statements within the meaning of the safe harbor provisions of the federal securities laws.
