ITEM 7. FINANCIAL STATEMENTS, PRO FORMA FINANCIAL INFORMATION AND EXHIBITS (c) Exhibits Exhibit No. Description of Exhibit 99.1 Press Release dated May 13, 2003 ITEM 9. REGULATION FD DISCLOSURE (INFORMATION PROVIDED UNDER ITEM 12. RESULTS OF OPERATIONS AND FINANCIAL CONDITION) Operations and Financial Information Furnished On May 13, 2003, the Company issued a press release announcing its fiscal second quarter 2003 financial and operating results. This press release is furnished as Exhibit 99.1, and incorporated herein by reference. In addition, the Company announced in a press release issued on May 2, 2003 that a webcast of a second quarter conference call would be held on May 13, 2003. The press release furnished herewith will be posted to the Company's website located at http://www.escotechnologies.com and can be viewed through the Investor Relations page of the website under the tab "Press Releases", although the Company 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 Company's operating results in a manner that is focused on the performance of the Company's ongoing operations. The Company 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 "Net earnings excluding the after-tax charges relating to the MSA and MTA," "EBIT from continuing operations," "EBIT excluding the after-tax charges relating to the MSA and MTA," "Free cash flow," and "EBITDA from continuing operations." The Company defines "Net earnings excluding the after-tax charges relating to the MSA and MTA" as net earnings excluding the special items described in the press release. These special items comprise a one-time charge resulting from the termination of a Manufacturing and Supply Agreement (MSA) with Whatman HemaSure Inc., and costs resulting from the Management Transition Agreement between the Company and its former Chairman (MTA). The Company's management uses this information in evaluating the results of the continuing operations of the Company and believes that this information provides investors with better insight into the period over period financial performance of the Company. The Company defines "EBIT from continuing operations" as earnings before interest and taxes. The Company's management evaluates the performance of its operating segments based on EBIT from continuing operations and believes that EBIT from continuing operations is useful to investors to demonstrate the operational profitability of the Company's business segments by excluding interest and taxes, which are generally accounted for across the entire Company on a consolidated basis. EBIT from continuing operations is also one of the measures used by management in determining resource allocations within the Company and incentive compensation. "EBIT excluding the after-tax charges relating to the MSA and MTA": The Company calculates this non-GAAP financial measure as EBIT of the Company's business operations for the respective period, excluding the special items described above in the discussion of "Net earnings excluding the after-tax charges relating to the MSA and MTA." The Company's management uses this information in evaluating the results of the continuing operations of the Company and believes that this information provides investors with better insight into the period over period financial performance of the Company. The Company defines "Free cash flow" as "Net cash provided by operating activities" less "Capital expenditures". The Company's management believes that free cash flow is useful to investors and management as a supplemental financial measurement in the evaluation of the Company's business and believes that free cash flow may provide additional information with respect to the Company's ability to meet its future debt service, capital expenditures and working capital requirements. Free cash flow can also be reinvested in the Company for future growth. The Company defines "EBITDA from continuing operations" as earnings before interest, taxes, depreciation and amortization. The Company's management uses EBITDA as a supplemental financial measurement in the evaluation of the Company's business and believes that EBITDA may provide additional information with respect to the Company's ability to meet its future debt service, capital expenditures and working capital requirements. The presentation of net earnings excluding the after-tax charges relating to the MSA and MTA, EBIT from continuing operations, EBIT excluding the after-tax charges relating to the MSA and MTA, free cash flow, and EBITDA from continuing operations, is intended to supplement investors' understanding of the Company's operating performance. The Company'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 Company specifically incorporates it by reference in a document filed under the Securities Act of 1933 as amended or the Exchange Act. Statements in this report, including Exhibit 99.1, regarding the Company's ability to negotiate a successful settlement and/or enforce the terms of the MSA, statements in the Chairman's comments concerning future closures, consolidations and relocations, the associated costs and resulting savings to be achieved, results to be achieved from future Filtration initiatives, future fiscal 2003 revenues, gains/charges and earnings 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 report. 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: further weakening of economic conditions in served markets; changes in customer demands or customer insolvencies; competition; intellectual property rights; the Company's successful exploitation of acquired intellectual property rights; the success of future Filtration initiatives adopted by Management; successful execution of planned facility closures, consolidations and relocations with regard to the Company's Puerto Rico facility and U.K. facility; the impact of FASB Interpretation No. 46; consolidation of internal operations; integration of recently acquired businesses; 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; litigation uncertainty; and the Company's successful execution of internal operating plans. 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.

                      ESCO ANNOUNCES SECOND QUARTER RESULTS

     St. Louis,  MO, May 13, 2003 - ESCO  Technologies  Inc.  (NYSE:  ESE) today
reported  that  net  earnings  for the  fiscal  second  quarter  ended  March 31
increased 8 percent to $5.6 million,  or $0.43 per share, from $5.2 million,  or
$0.40 per share in the prior year second quarter. The second quarter fiscal 2003
reported  results include two previously  disclosed  after-tax  charges totaling
$1.3 million, or $0.10 per share. The after-tax charges include $0.9 million, or
$0.07 per share,  resulting from the termination of a  Manufacturing  and Supply
Agreement (MSA) with Whatman HemaSure Inc. (Whatman), and $0.4 million, or $0.03
per share,  resulting from the Management Transition Agreement (MTA) between the
Company  and its former  Chairman  who  retired  in April  2003.

     Net earnings,  excluding the after-tax  charges related to the MSA and MTA,
increased  34 percent to $6.9 million, or $0.53 per share, compared to the $5.2
million,  or $0.40 per share,  in the prior year second  quarter.  The  attached
financial  tables  provide a  reconciliation  of GAAP  reported  results  to the
results of operations excluding the MSA and MTA charges.

     Under the terms of the MSA, the  Company's  termination  based on Whatman's
breach of contract  entitles  ESCO to recover its damages and certain  specified
costs.  The  parties are  involved  in  settlement  discussions  and  Management
believes  it will be  successful  in  negotiating  a  settlement,  or  otherwise
enforcing its contractual rights and expects to recover an amount at least equal
to the charge taken in the fiscal  second  quarter.

     In April 2003,  the Company  sold its Rantec Power  Systems  Inc.  (Rantec)
subsidiary  for $6 million  plus  future  consideration.  The  Rantec  financial
results, previously reported in the "Other" operating segment, are accounted for
as "discontinued  operations" at March 31, 2003.

     Sales for the second  quarter of fiscal 2003 increased 32 percent to $112.2
million  from $85.1  million in the prior year  second  quarter.  Communications
segment sales increased 85 percent to $37.8 million as a result of significantly
higher shipments of DCSI's Automatic Meter Reading (AMR) equipment.  Test

                                    - more -


Add One segment sales increased 46 percent in the second quarter to $24.3 million due to $2.4 million of sales from the recently acquired acoustic business, additional test chamber sales, and sales from the Company's Asian operations. Filtration segment sales increased 4 percent to $50.1 million primarily as a result of higher product shipments from the Company's Filtertek subsidiary. Earnings Before Interest and Taxes (EBIT) from continuing operations for the second quarter of fiscal 2003 were $9.5 million compared to $8.1 million in the comparable prior year quarter. The net increase in EBIT resulted from the profit contributions of the Company's Communications segment. Test segment EBIT increased over the comparable prior year quarter as a result of the significant increase in sales. EBIT in the Filtration segment was impacted in this fiscal year's second quarter by a pretax charge of $1.5 million related to the MSA and the continuing investment in Microfiltration and Separations. The MTA pretax charge of $0.7 million is included in the "Other" segment. EBIT, excluding the MSA and MTA, increased during the second quarter of fiscal 2003 to $11.7 million, or 10.4 percent of sales, compared to the $8.1 million, or 9.5 percent of sales, in the prior year. For a reconciliation of EBIT and of EBIT excluding the MSA and MTA, see the attached financial tables. Six Months Year-to-Date Net earnings for the six-month period increased 22 percent to $12.2 million, or $0.93 per share, from $10.0 million, or $0.77 per share in the prior year six-month period. The year-to-date fiscal 2003 reported results include six month year-to-date after-tax charges of $1.7 million, or $0.13 per share related to the MSA and MTA. Year-to-date net earnings, excluding the after-tax charges related to the MSA and MTA, increased 39 percent to $13.9 million, or $1.06 per share. The attached financial tables provide a reconciliation of GAAP reported results to the results of operations excluding the MSA and MTA. Six months year-to-date sales increased 33 percent to $221.5 million from $166.7 million in the prior year comparable period. Communications segment sales increased 94 percent to $77.4 million as a result of significantly higher shipments of AMR equipment, primarily to PPL. Test segment sales increased by 27 percent in the first six months to $43.9 million due to the revenues from the acoustic business acquisition, additional chamber sales and sales from the Company's recently established Asian operations. Filtration segment sales increased 8 percent to $100.2 million. Earnings Before Interest and Taxes (EBIT) from continuing operations for the first six months of fiscal 2003 increased 28 percent to $19.9 million compared to $15.6 million in the comparable prior year period. The net increase in EBIT resulted from the profit contributions of the Company's Communications segment. Test segment EBIT increased slightly, as the contribution from the increased sales was offset by the investments to expand the Company's presence in China and Japan. EBIT in the Filtration segment was - more -

Add Two impacted in this year's six-month period by a pretax charge of $1.5 million related to the MSA, the continuing investment in engineering and new product development, and the costs related to establishing a new German sales and support operation. The MTA pretax charge of $1.4 million is included in the "Other" segment. EBIT, excluding the MSA and MTA, increased during the first six months of fiscal 2003 to $22.8 million, or 10.0 percent of sales, compared to the $15.6 million, or 9.4 percent of sales, in the prior year six months. For a reconciliation of EBIT and of EBIT excluding the MSA and MTA, see the attached financial tables. New orders in the second quarter and first six months of fiscal 2003 were $102.3 million and $204.4 million, respectively, resulting in a backlog at March 31, 2003 of $268.2 million. These amounts exclude discontinued operations. During the first six months of fiscal 2003, the Company generated $10.0 million of free cash flow, defined as "Net Cash Provided by Operating Activities - - Continuing Operations" less "Capital Expenditures - Continuing Operations." For a reconciliation of free cash flow, see the attached financial tables. Victor L. Richey, Chairman and Chief Executive Officer, commented, "Notwithstanding the MSA charge related to our dispute with Whatman, our second quarter results in the aggregate were consistent with our expectations. However, the disparity in the contribution between the segments continues to be an issue in the context of meeting our longer-term objectives. "In Communications, we are getting excellent results. Our focus continues to be on strengthening the organization and broadening our product offering in order to capitalize on the large and growing market for automatic meter reading equipment. "In the Test business, where the economy has presented significant challenges over the past 18 months, our results are improving. The improvement is a product of both a somewhat better market environment and the actions we have taken to reduce our costs. As an additional step to improve our cost and competitive position, we are streamlining our U.K. operations and centralizing the management of our European Test operations. As indicated in the Business Outlook Section of this release, the European consolidation will result in a second half pretax charge of between $0.3 to $0.6 million. The consolidation will be complete in fiscal 2003. These cost savings, coupled with the top line growth we expect from our acoustic's business and recent Asian investments, should position us well for the attainment of our aggregate longer-term objectives in this segment. "In Filtration, our results have been below expectations. While I am extremely disappointed by our operating results in Filtration, I am pleased that we concluded an agreement to resolve an intellectual property dispute related to certain filtration products which will result in a pretax gain in the third quarter between $2.1 and $2.3 million and contribute approximately $7.0 million to our third quarter cash flow. - more -

Add Three "With respect to the erosion in our Filtration operating results, and after having completed a thorough review of our operations and investments, I believe that a number of significant steps are warranted to reposition our Filtration business as a significant contributor. In that regard, at our May meeting, the Company's Board of Directors approved Management's proposal to proceed with the closure of our Filtration operation in Puerto Rico. The manufacturing will be moved to existing Filtertek facilities in Hebron, Illinois and Juarez, Mexico. The closure will result in a third quarter charge of $3.0 million to $4.0 million primarily related to writing down the Puerto Rico facility to the appraised value. The cost of effecting the move over the next 12 months is expected to be between $1.5 and $2.0 million. When the closure and relocation is completed in fiscal 2004, we expect this action to result in at least $2.0 million of annual cost savings." Mr. Richey continued, "With respect to the investments we have made in Microfiltration and Separations which currently are significantly dilutive to our earnings, my current assessment is that while the long-term prospects may be good, we will be better served by narrowing our focus. To address this issue we are considering a wide range of alternatives to deal with the performance of the Microfiltration and Separations business. The actions being considered may result in a material charge to future earnings. "I am certain that when we complete our Filtration initiatives we will see meaningful improvement in the operating results and cash flow. I also continue to believe that a more focused Filtration business with a better cost and competitive position can be a significant contributor to the growth and prosperity of our company. "As previously announced, in April we completed the sale of Rantec Power Systems Inc. (Rantec) to a group of investors primarily comprised of Rantec's management. The sale will result in a pretax gain of between $1.5 to $2.0 million in the third quarter. The sale of Rantec will allow key ESCO management personnel to focus more fully on the reorientation of our Filtration business and the development of our best opportunities across the company. "I appreciate that what I have outlined is a lot to digest. To clarify the financial impact of these initiatives we have included a table in the Business Outlook section of this release. I also respect that the actions outlined reflect a change in the near-term view of what we thought could be accomplished in Filtration. However, I believe the actions are constructive and support meeting the long-term objectives we have previously communicated. "Finally, I want to summarize my view of ESCO today. In Communications, we are getting extraordinary results and have good prospects. In Test, we have excellent positions in our end markets and have largely completed the actions required to deliver sustained profitable growth. In Filtration, we have initiated significant actions to improve the profitability and cash flow and we are reviewing additional steps to address the remaining issues. Taken together, I am convinced that we will meet the mission and deliver continued improvement in shareholder value." - more -

Add Four Fiscal 2003 Business Outlook Statements contained in the preceding and following paragraphs are based on current expectations. These statements are forward-looking, and actual results may differ materially. Revenues Absent any additional fiscal 2003 acquisitions or divestitures, Management expects year-over-year revenue growth of greater than 20 percent. In the Communications segment, the Company expects revenue growth of greater than 40 percent excluding any contribution from fiscal 2003 AMR system orders from new customers in the Investor Owned Utility (IOU) sector. In the Test segment, we anticipate revenue growth of at least 25 percent, including the sales contribution of the acoustic business acquired December 31, 2002. Filtration segment revenue growth is expected to be in the low to mid-single-digit range. Second Half Gains / Charges As indicated in the Chairman's commentary, the Company expects to incur certain gains and charges throughout the second half of fiscal 2003 related to the following items and events. A summary table is provided below with narrative following the table. The table and the footnotes should be read together. Items (1), (2) and (3) have been identified in previous communications. Total (Second Half) FY 03 ($ in millions)/Gains (Charges) Future Pretax FY03 Pretax Timing Total Cash ------------------------------ ------------ ----------- ------ ---------- (1)Patent litigation settlement $5.9 - $6.1 $2.1 - $2.3 Q3 $7.0 - $7.3 (2)Rantec divestiture $1.5 - $2.0 $1.5 - $2.0 Q3 $6.0 (3)Whatman MSA settlement $1.5 - $2.3 $1.5 - $2.3 $0 - $0.8 (4)Puerto Rico facility exit ($3.0)-($4.0) ($3.0)-($4.0) Q3 $4.0 - $5.0 (5)Puerto Rico severance/move ($1.5)-($2.0) ($0.8)-($1.1) Q3/Q4($1.5)-($2.0) (6) U.K. Test move/restructure ($0.3)-($0.6) ($0.3)-($0.6) Q3/Q4($0.2)-($0.5) ----- ----- ----- ----- - ------ ----- Totals/Ranges $2.3 - $5.6 ($0.6)- $2.5 $14.5 -$17.4 Note: The table does not include any potential impact of the alternatives being considered to reorient the Microfiltration and Separations business as discussed in the Chairman's commentary. (1) During the third quarter, the patent litigation, related to the defense of certain revenue generating patents used in the Company's Filtration / Fluid Flow business, was settled with a $7.3 million cash payment expected to be received by June 30, 2003. For accounting purposes, the pretax gain is calculated as the gross proceeds, less the deferred legal costs incurred by the Company to defend this patent. The net gain is allocated to past and future licensing periods. The remaining unrealized gain will be recognized in pretax income over the remaining eight years of the patent. (2) The Rantec gain will be finalized after the post-closing balance sheet is prepared, and the pretax gain will be recognized in the fiscal third quarter of 2003. This gain will be included in discontinued operations. Cash of $6.0 million was received in April at closing. The Company is also entitled to additional consideration based on the future operating results of Rantec. - more -

Add Five (3) Management has initiated litigation against Whatman in order to recover the amount it is entitled to under the terms of the MSA contract. The Company was required to take the $1.5 million pretax charge in the fiscal second quarter related to the buyout of the remaining lease term for manufacturing equipment that was unique to the production of leukocyte filters. In accordance with GAAP, the charge was required because a settlement was not reached before the date of this release. Since the equipment lease buy-out amount has been fully expensed, the proceeds of any settlement or court determined award will be recognized as a pretax gain when the settlement is finalized or litigation is concluded. This item also relates to the Filtration / Fluid Flow operating segment. (4) The Puerto Rico facility exit costs include the write-down of the building and equipment from their respective carrying value to their estimated net realizable value. Management expects the building to be sold within the next 18 months. These exit costs will be recognized as a third quarter fiscal 2003 charge in accordance with recently adopted accounting rules related to exit and restructuring costs and will be included in the Filtration / Fluid Flow operating segment. (5) The Puerto Rico severance and move costs consist of personnel severance costs including the Company fulfilling its collective bargaining obligations with the Union representing the hourly employees at this location and costs relating to physically moving the manufacturing equipment to its new location and other related costs, and will be recognized as period costs when incurred. Management expects the move to be complete within the next 12 months. (6) The U.K. Test move / restructure costs primarily relate to severance, write-offs of leasehold improvements, and moving costs as a result of consolidating a portion of the operating facilities. These costs will be included in the Test operating segment. Synthetic Lease Obligation As previously disclosed in the Company's Form 10-Q for December 31, 2002, the Company has a $31.5 million obligation under a synthetic lease facility arranged by Bank of America. For GAAP purposes, this is accounted for as an operating lease. This obligation is secured by leases of three manufacturing locations, two of which are located in Oxnard, CA (Filtration/Fluid Flow) and the other in Cedar Park, TX, (Test) as well as a $10.6 million letter of credit issued under the Company's $70 million credit facility. The leases expire on December 29, 2005 at which time the Company will be required to extend the leases on terms to be negotiated, purchase the properties for $31.5 million, or refinance the obligation. The Financial Accounting Standards Board (FASB) recently issued Interpretation No. 46, "Consolidation of Variable Interest Entities" which provides guidance related to identifying variable interest entities and determining whether such entities should be consolidated. The Company is currently reviewing the impact of this new FASB interpretation and the possible consolidation of the synthetic lease obligation. - more -

Add Six Upon consolidation, the Company expects to record an after-tax charge reported as a cumulative effect of a change in accounting principle of approximately $1.4 million, or $0.11 per share, during the fiscal 2003 fourth quarter. Earnings Per Share Beyond the items included in the "Second Half Gains / (Charges)" section above, and any charge that might result from the actions outlined in the Chairman's commentary regarding the potential reorientation of the Microfiltration and Separations business, there has been no fundamental change in our aggregate outlook for fiscal 2003. Considering the numerous potential gains and charges described above which will impact both the amount and the timing of GAAP reported earnings per share (EPS) throughout the third and fourth fiscal quarters, and giving consideration to the uncertainties and estimates surrounding the outcome of the final amounts of these items, Management estimates the range of fiscal 2003 GAAP EPS to be between $1.75 to $2.00 per share, including the $0.11 per share after-tax charge reported as a cumulative effect of a change in accounting principle related to the Synthetic Lease, but excluding any charge that might arise from actions taken to reorient the Microfiltration and Separations business.
