ITEM 2.02. RESULTS OF OPERATIONS AND FINANCIAL CONDITION Today, November 16, 2004, the Registrant is issuing a press release (Exhibit 99.1 to this report) announcing its fiscal 2004 fourth quarter and year-end financial and operating results. See Item 7.01, Regulation FD Disclosure below. ITEM 7.01. REGULATION FD DISCLOSURE Today, the Registrant is issuing a press release announcing its fiscal 2004 fourth quarter and year-end 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. 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, as well as "EBIT from continuing operations," "EBIT margin," "operational" 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 and relocation 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, (vi) the charge resulting from an equipment lease termination related to the Whatman Hemasure contract dispute, (vii) the interest rate swap charge, (viii) the cumulative effect of accounting charge related to the synthetic lease obligation, (ix) gain on the sale of Rantec Power Systems, Inc., which was divested and is shown as "discontinued operations" in fiscal 2003 and (x) the results of operations from the MicroSep businesses which were divested in fiscal 2004 and are shown as "discontinued operations" in fiscal 2004 and 2003. 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 costs related to the shutdown of the Puerto Rico facility, the gain from settlement of the patent litigation, and the Whatman Hemasure charge. 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, comprehensive income (loss), or any other measure as determined in accordance with GAAP.

                    ESCO ANNOUNCES FISCAL YEAR 2004 RESULTS
                    ---------------------------------------


     St. Louis, MO, November 16, 2004 - ESCO Technologies Inc. (NYSE: ESE) today
announced its results for the fourth quarter and fiscal year ended September 30,
2004. The results of operations  reflect certain  repositioning  items that were
announced and described in detail in previous  releases in fiscal 2003 and 2004.
These included  severance and move charges  incurred in 2004 and 2003 related to
the exit and relocation of Filtertek's Puerto Rican manufacturing  facility; the
fiscal  2004  divestiture  of the  Microfiltration  and  Separations  businesses
(MicroSep)  which is accounted for as discontinued  operations;  the fiscal 2003
gain related to a patent  litigation  settlement;  the fiscal 2003 interest rate
swap charge; and the fiscal 2003 costs associated with the Management Transition
Agreement (MTA) and the Whatman  Manufacturing  and Supply  Agreement (MSA). The
reconciliation of GAAP reported  earnings to "Operational"  earnings is included
in the  Exhibits  attached  to this  release.  The  Company  believes  that  the
presentation of "Operational"  earnings provides  meaningful  additional insight
into the Company's performance.

Add One Results of Operations (in millions, except EPS) - ----------------------------------------------- Sales and net earnings for the fiscal 2004 and 2003 fourth quarters and fiscal year periods ended September 30 are noted below (dollars in millions, except EPS): 4th Qtr. - FY 2004 Sales Net Earnings Diluted EPS ------------------ ----- ------------ ----------- GAAP $115.6M $12.1M $0.91 Operational $115.6M $12.4M $0.93 4th Qtr. - FY 2003 Sales Net Earnings Diluted EPS ------------------ ----- ------------ ----------- GAAP $105.6M $(57.5M) $(4.33) Operational $105.6M $8.8M $0.67 FY 2004 Sales Net Earnings Diluted EPS ------- ----- ------------ ----------- GAAP $422.1M $35.7M $2.68 Operational $422.1M $38.8M $2.91 FY 2003 Sales Net Earnings Diluted EPS ------- ----- ------------ ----------- GAAP $396.7M $(41.1M) $(3.13) Operational $396.7M $32.9M $2.51 Sales - ----- Fiscal 2004 fourth quarter consolidated sales of $115.6 million were $10.0 million, or 9 percent higher than 2003 fourth quarter sales. Fiscal year 2004 sales of $422.1 million increased $25.4 million, or 6 percent over total sales in 2003. Favorable foreign currency values resulted in approximately $1.3 million and $6.5 million of the sales increases realized in the fourth quarter and total year 2004, respectively, as compared to the prior year periods. On a segment basis for 2004, Communications sales increased 7 percent in the quarter and decreased 3 percent for the year; Filtration sales increased 10 percent in the quarter and 6 percent for the year; and Test sales increased 13 percent in the quarter and 22 percent for the year, as compared to the respective prior year periods. - more -

Add Two Communications segment sales increased in the fourth quarter as a result of higher shipments of Comtrak's SecurVision video security products, which generated $3.8 million in sales during the fourth quarter of 2004 versus $1.2 million of sales in the 2003 fourth quarter. Total SecurVision sales in 2004 were $5.6 million compared to $8.4 million in 2003. The decreased sales for the full year were a result of a previously discussed 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 resumed during the fourth quarter of fiscal 2004. Also within the Communications segment, sales of DCSI's Automatic Meter Reading (AMR) equipment to electric utility customers were approximately $35 million in both fiscal 2004 and 2003 fourth quarters. Sales to PPL Electric Utilities Corporation (PPL) decreased approximately $12.5 million in the current year's fourth quarter compared to the fourth quarter of fiscal 2003 due to the wind-down of the PPL contract. Sales to PPL were $1.0 million and $21.6 million in the 2004 fourth quarter and full year, respectively, compared to $13.6 million and $63.9 million in the 2003 fourth quarter and full year, respectively. DCSI's sales to electric utility cooperative customers (COOP) and customers other than PPL increased 58 percent during fiscal 2004 to $110.5 million, from $70.0 million in fiscal 2003. Fiscal year 2004 sales decreased approximately $1.8 million at DCSI compared to the prior year, primarily as a result of $42.3 million less sales to PPL in the current year related to the wind-down of the contract. Filtration segment sales increased in the fourth quarter and full year of fiscal 2004 primarily as a result of higher defense shipments at VACCO; higher sales of industrial products at PTI; and favorable foreign currency exchange rates related to Filtertek's European operations. - more -

Add Three Test segment sales increased in the fourth quarter of 2004 due to the completion of a large chamber in Asia and additional antenna and other component sales. For the full year, Test sales increased significantly over prior year as a result of two large test chamber installations in Europe, increased volume from the Company's Asian operations, and higher sales of government and industrial shielding products. Earnings Before Interest and Taxes (EBIT) - ----------------------------------------- EBIT from continuing operations for the fourth quarters and full year periods ended September 30, 2004 and 2003 was affected by certain gains and charges described above which are presented in detail in the financial Exhibits attached at the end of this release. In the fourth quarters of fiscal 2004 and 2003, the pretax charges in continuing operations related to these items were zero and $1.9 million, respectively. For the full fiscal years 2004 and 2003, the pretax charges in continuing operations related to these items were $1.3 million and $7.8 million, respectively. These items are included in "Earnings before income taxes" in the Exhibits. On a segment basis, items that impacted EBIT from continuing operations as a percent of sales ("EBIT margin") during the fourth quarter and full year of fiscal 2004 include the following. In the Communications segment, EBIT margin for fiscal year 2004 is higher than prior year due to the favorable sales mix of AMR products resulting from additional sales to the COOP market, and significant cost reductions realized on certain components. The 2004 fourth quarter EBIT margin was also positively impacted by the higher shipments of SecurVision products. - more -

Add Four In the Filtration segment, EBIT margin improved in the fourth quarter of fiscal 2004 primarily due to higher defense sales at VACCO and increased sales of industrial products at PTI. The full year 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 being marketed for sale. In the Test segment, EBIT margin improved in the full year as a result of the significantly higher sales volume recognized in fiscal 2004. The 2004 fourth quarter EBIT margin was slightly lower than the prior year fourth quarter due to changes in sales mix resulting from a higher amount of large chamber deliveries that have lower margins than the component products and service business revenues. The fiscal 2003 amounts included costs associated with the U.K. facility consolidation mentioned in earlier releases. The Corporate office operating expenses were higher during the fourth quarter of 2004 than previously anticipated as a result of additional compensation related costs. Effective Tax Rate - ------------------ The effective tax rate for the fourth quarter of fiscal 2004 was 35.7 percent and was impacted by the favorable foreign income tax rate differential. The actual tax rate in the fourth quarter of 2004, when compared to the previously anticipated tax rate of 38 percent, generated a positive variance of $0.03 per share. - more -

Add Five New Orders - ---------- New orders received in the 2004 fourth quarter and fiscal year were $116.5 million and $408.2 million, respectively, resulting in a backlog at September 30, 2004 of $249.1 million. New orders received in Filtration, Communications and Test were $165.4 million, $116.0 million, and $126.8 million in fiscal year 2004 respectively, and $180.4 million, $102.1 million, and $102.3 million in fiscal year 2003, respectively. Cash Flow - --------- In the fourth quarter of 2004, the Company generated $21.7 million of free cash flow from continuing operations. During fiscal year 2004, the Company generated $44.6 million of free cash flow from continuing operations, and ended the year with $72.3 million of cash and $0.5 million of debt. 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 - ------------------------ During the fourth quarter of fiscal 2004, the Company spent approximately $10 million to repurchase 156,200 shares of its outstanding stock under its existing stock repurchase program. As of September 30, 2004, the Company has authorization to repurchase approximately 900,000 shares under the current program, which expires September 30, 2006. - more -

Add Six 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. In the fourth quarter of fiscal 2004, the Company recorded the final post-closing balance sheet adjustments that resulted in a $0.3 million after-tax charge recorded in discontinued operations. Chairman's Commentary - --------------------- Vic Richey, Chairman and Chief Executive Officer, commented, "Our fiscal 2004 fourth quarter results were better than we anticipated. In addition to the impact of a lower effective tax rate in the fourth quarter, we also had a broad based operational contribution to the upside. All three of our operating segments exceeded the sales and EBIT expectations we had as we entered the quarter." Mr. Richey continued, "Reflecting on the full year results, I believe that our financial performance clearly demonstrated that we met our primary objective, which was to strengthen our foundation as we begin to add emphasis to our long-term growth initiatives. In particular, I would point to our EBIT margin, which grew on an operational basis from 12.8 percent in fiscal 2003 to 14.5 percent in fiscal 2004, our free cash flow from continuing operations which reached $45 million in fiscal 2004 and the fact that we ended the year with approximately $72 million of cash net of debt. Collectively, these measures reflect not only a stronger core but also the capacity we have to fully support our growth programs and our share repurchase plans." Addressing the future, Mr. Richey commented, "While we are projecting modest EPS growth in fiscal year 2005, absent any significant contributions from major new investor owned - more -

Add Seven utility programs or an acquisition, I believe we have positions and opportunities that support longer term revenue and EPS growth rates that are consistent with our previously established goals of 10 percent and 15 percent, respectively. One prominent reason for the moderation of our 2005 EPS outlook is our plan to significantly increase our support of the Communications business, in spite of our fiscal 2005 revenue outlook for this segment, which is projected to be flat to modestly down year-over-year. Specifically, our fiscal 2005 baseline plan includes a year-over-year increase in SG&A of $3.2 million, or 14 percent, in the Communications segment primarily directed at marketing, project management, and new product development. While this decision will cost us 15 cents of EPS in fiscal 2005, I am convinced, based on the current level of activity in the IOU segment of the AMR market, that it is appropriate from a long-term growth perspective. "From a management standpoint going forward, we are not looking at any major course corrections. Having stabilized our base through the recently completed repositioning actions, we are now placing more emphasis on growing the top line. "While we will continue to vigorously work our cost and competitive position, long term revenue growth should play a more prominent role than it has in the recent past with respect to meeting our long term goals. Fiscal 2005 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. - more -

Add Eight The fiscal 2005 Business Outlook described below does not include the impact of potential acquisitions, or the impact of any significant orders from new investor owned utility customers that may be entered into during the fiscal year. Revenues - -------- Management expects fiscal 2005 year-over-year revenue growth in Filtration in the range of 2 to 5 percent. In Test, Management expects revenue growth of 4 to 8 percent, and in Communications, Management expects revenue to be flat to down 3 percent. The expected decrease in Communications is due to the fiscal 2004 wind-down of the PPL contract that generated $21.6 million in sales, and the Idaho Power phase one and Bangor Hydro contracts that generated combined sales of approximately $8.5 million. EBIT Margin - ----------- Management expects EBIT margins to be in the following ranges: Filtration margins should be in the range of 13 to 15 percent; Test margins should be in the range of 9 to 11 percent; and Communications margins should be in the range of 27 to 29 percent. Corporate operating expenses are expected to be consistent with fiscal 2004 amounts. Earnings Per Share - ------------------ Management estimates fiscal 2005 EPS to be in the range of $2.95 to $3.15 per share, with the first half of the fiscal year EPS being between $1.50 and $1.60 per share. The effective tax rate for fiscal 2005 is expected to be approximately 38 percent. - more -

Add Nine Share Repurchase - ---------------- Management intends to continue its open market share repurchase program during fiscal 2005, and is currently planning to spend an additional $25 million to repurchase its outstanding shares in the near term. Conference Call - --------------- The Company will host a conference call today, November 16, at 9:30 a.m., Central Time, to discuss the Company's fourth quarter and full year operating results.

Forward-Looking Statements - -------------------------- Statements in this press release regarding the results of real estate sales, the level of contributions from each segment, future investments, potential acquisitions, potential customer contracts, share repurchases, fiscal 2005 corporate operating expenses, the fiscal 2005 effective tax rate, future fiscal 2005 revenues, EBIT, EPS, SG&A, longer term revenue, 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. Investors are cautioned that such statements are only predictions and speak only as of the date of this release, and the Company undertakes no duty to update. - more -

Add Ten The Company's actual results in the future may differ materially from those projected in the forward-looking statements due to risks and uncertainties that exist in the Company's operations and business environment including, but not limited to: weakening of economic conditions in served markets; changes in customer demands or customer insolvencies; competition; intellectual property rights; technical difficulties; the availability of selected acquisitions; the timing, pricing and availability of shares offered for sale; unforeseen charges impacting corporate operating expenses; the performance of the Company's international operations; successful execution of the planned sale of the Company's Puerto Rico facility; delivery delays or defaults by customers; termination for convenience of customer contracts; timing and magnitude of future contract awards; performance issues with key suppliers and subcontractors; collective bargaining and labor disputes; changes in laws and regulations including changes in accounting standards and taxation requirements; changes in foreign or U.S. business conditions affecting the distribution of foreign earnings; costs relating to environmental matters; litigation uncertainty; and the Company's successful execution of internal operating plans.
