ITEM 2.02.  RESULTS OF OPERATIONS AND FINANCIAL CONDITION

Today,  May 10, 2005, the Registrant is issuing a press release (Exhibit 99.1 to
this report)  announcing its fiscal 2005 second quarter  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 2005
second quarter 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,  and (ii) the  results of  operations  from the
MicroSep  businesses  which  were  divested  in  fiscal  2004  and are  shown as
"discontinued  operations" in fiscal 2004. 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  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 SECOND QUARTER RESULTS


     St. Louis,  MO, May 10, 2005 - ESCO  Technologies  Inc.  (NYSE:  ESE) today
announced  its results for the fiscal 2005 second  quarter ended March 31, 2005.

     Net earnings  for the fiscal 2005 second  quarter  were $10.4  million,  or
$0.80 per share compared to net earnings of $5.4 million,  or $0.40 per share in
the second  quarter of fiscal 2004.  The prior  year's  second  quarter  results
included a net loss from discontinued  operations of ($2.2) million,  or ($0.17)
per share,  and the  after-tax  charges  related to the exit and shutdown of the
Puerto Rican facility of ($0.5) million,  or ($0.03) per share.  Excluding these
items,  prior year second quarter  "Operational"  earnings as defined in earlier
releases were $8.1 million, or $0.60 per share.

     Net earnings for the first six months of fiscal 2005 were $20.9 million, or
$1.60 per share  compared to net earnings of $11.5  million,  or $0.87 per share
for the first six months of fiscal 2004.  The prior year results  included a net
loss from discontinued  operations of ($2.6) million,  or ($0.19) per share, and
the  after-tax  charges  related to the exit and  shutdown  of the Puerto  Rican
facility of ($1.0) million,  or ($0.08) per share.  Excluding these items, prior
year first six months "Operational" earnings as defined in earlier releases were
$15.2 million, or $1.14 per share.

                                    - more -

Add One A reconciliation of the prior year GAAP reported earnings to "Operational" earnings is included in the Exhibits attached to this release. The Company believes that the presentation of fiscal 2004 "Operational" earnings provides meaningful additional insight into the Company's performance. Sales Fiscal 2005 second quarter sales of $106.2 million were $4.0 million, or 4 percent higher than 2004 second quarter sales of $102.2 million. Fiscal 2005 year-to-date sales of $210.5 million were $12.0 million, or 6 percent higher than 2004 year-to-date sales of $198.6 million. Favorable foreign currency values resulted in approximately $0.8 million and $2.4 million of the sales increases realized in the 2005 second quarter and year-to-date periods, respectively. On a segment basis for the fiscal 2005 second quarter, Communications sales increased 19 percent; Filtration / Fluid Flow ("Filtration") sales decreased 3 percent; and Test sales decreased 2 percent as compared to the prior year period. Year-to-date, fiscal 2005 Communications sales increased 13 percent; Filtration sales increased 4 percent; and Test sales increased 2 percent as compared to the first six months of fiscal 2004. Communications segment sales increased in the second quarter as a result of higher shipments of Comtrak's SecurVision video security products, which generated $3.5 million in sales during the second quarter of 2005 versus $0.4 million of sales in the 2004 second quarter. Year-to-date sales of SecurVision products were $10.6 million in 2005 as compared to $0.9 million in 2004. Also within the Communications segment, sales of DCSI's Automatic Meter Reading (AMR) equipment to electric utility customers were $32.6 million in the 2005 second quarter compared to $29.9 million in the prior year second quarter. Sales to PPL Electric Utilities Corporation (PPL) decreased approximately $7.0 million in the current-year's second quarter compared to the second quarter of fiscal 2004 due to the completion of the PPL contract. Sales - more -

Add Two to PPL were $0.4 million and $7.4 million in the second quarters of fiscal 2005 and 2004, respectively. DCSI's sales to electric utility cooperative customers (COOP) and customers other than PPL increased 43 percent during the 2005 second quarter to $32.2 million, from $22.5 million in the prior year second quarter. Filtration segment sales decreased during the second quarter of fiscal 2005 primarily as a result of lower defense spares shipments at VACCO and lower automotive shipments at Filtertek. These decreases were partially offset by higher shipments of commercial and military aerospace products at PTI. Year-to-date, Filtration segment sales increased due to the additional volume of commercial and military aerospace products at PTI. Test segment sales decreased slightly during the second quarter of 2005 due to higher sales realized in 2004 at the Company's European operations from two large chamber projects. In addition, current-year sales were lower-than-expected due to the timing of the completion of a test chamber installation in Japan and certain government shielding projects, which were completed in April 2005 and will be recognized in the fiscal 2005 third quarter. These second quarter timing items were partially offset by significantly higher components sales. Year-to-date, the sales increase was the result of additional test chamber installations, component sales, and government shielding projects. Earnings Before Interest and Taxes(EBIT) - ---------------------------------------- On a segment basis, items that impacted EBIT as a percent of sales ("EBIT margin") during the second quarter of fiscal 2005 included the following. In the Communications segment, EBIT margin for the 2005 second quarter was higher than the prior year period due to the significant increase in shipments of SecurVision products. The 2005 second quarter EBIT margin was also positively impacted by the favorable sales mix of AMR products resulting from additional sales to the COOP market and cost reductions realized on certain components. - more -

Add Three In the Filtration segment, EBIT margin improved during the 2005 second quarter and year-to-date periods primarily due to higher aerospace sales at PTI and improved operating efficiencies realized at Filtertek subsequent to exiting the Puerto Rican facility. In addition, Filtertek's current-year EBIT margin was favorably impacted by $0.3 million in the second quarter and $0.9 million year-to-date as a result of a cost reimbursement realized at Filtertek from a medical device customer related to a shortfall in their actual purchases versus the minimum contractually guaranteed amount. During the second quarter of 2005, Filtertek signed an agreement to license certain of its patents related to Needle-Free Connectors to a third party for $1.5 million in cash and recognized $0.2 million of profit related to this transaction. These improvements were partially offset by lower margins realized during the second quarter of 2005 at VACCO resulting from the decreased sales of defense spares. The prior year EBIT margin in the Filtration segment was negatively 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. In the Test segment, EBIT margin was higher in the second quarter of 2005 due to the favorable changes in sales mix resulting from additional component sales, but was lower in the current year-to-date period primarily as a result of approximately $0.3 million in installation cost overruns incurred during the first quarter of fiscal 2005 on government-shielding projects located in particularly volatile areas of the world, and higher costs of steel and copper. The Corporate office operating expenses were comparable in the second quarters of fiscal 2005 and 2004, respectively. EBIT from continuing operations for the prior year periods was affected by certain charges which are presented in detail in the financial Exhibits attached at the end of this release. - more -

Add Four In the second quarter and year-to-date periods of fiscal 2004, the pretax charges in continuing operations related to these items were $0.6 million and $1.3 million, respectively. These items are included in "Earnings before income taxes" in the Exhibits. New Orders - ---------- New orders received during fiscal 2005 were $113.8 million and $215.4 million for the second quarter and six-month periods, resulting in a backlog of $253.9 million at March 31, 2005. New orders received in Filtration, Communications and Test were $60.5 million, $27.4 million, and $25.9 million in the 2005 second quarter, respectively. Year-to-date, fiscal 2005 new orders received in Filtration, Communications and Test were $99.8 million, $62.7 million, and $53.0 million, respectively. The Filtration amounts noted above include the orders for anti-icing valves for the T-700 engine utilized on numerous airframes including the Blackhawk Helicopter, and for quiet valves and manifold assemblies used on the Virginia Class Submarine. Both orders were multi-year follow-on awards and were previously discussed in the February 4, 2005, Earnings Release. Cash Flow - --------- The Company generated $12.2 million and $24.5 million of free cash flow during the second quarter and year-to-date periods ended March 31, 2005, respectively. Free cash flow is defined as "Net Cash Provided by Operating Activities" less "Capital Expenditures." For a reconciliation of free cash flow, see the Exhibits attached to this release. Stock Repurchase Program - ------------------------ No shares were repurchased during the second quarter of fiscal 2005. The Company spent $24.9 million during the first quarter of fiscal 2005 to repurchase 335,000 shares of its outstanding stock under its existing stock repurchase program. As of March 31, 2005, approximately 575,000 shares remain available for repurchase by the Company under the current program, which expires September 30, 2006. - more -

Add Five Chairman's Commentary - --------------------- Vic Richey, Chairman and Chief Executive Officer, commented, "Our fiscal 2005 second quarter revenues were at the low end of our internal expectations largely as a result of the well-publicized weakness in the automotive sector, which impacted our sales of fuel and transmission filters. Despite the lower automotive related revenues, our second quarter earnings per share were at the high end of our previous guidance, primarily resulting from mix-driven improvements in our Test segment and higher-than-anticipated sales of video security products." Mr. Richey continued, "While our full year outlook has not changed significantly, as a result of the strength of our second quarter results, and given the additional visibility we have at mid-year, our full year EPS guidance is being raised and the range tightened. Our current expectations are for full year EPS in the range of $3.10 to $3.20 per share, versus our previous guidance of $2.95 to $3.15 per share. "While we are taking nothing for granted, I believe we are very well-positioned to deliver our 2005 numbers. The bulk of our attention at this point is directed at capturing opportunities and successfully implementing near-term initiatives which will support continued profitable growth in 2006 and beyond. "In Filtration, we have several niche opportunities for growth and more substantial opportunities for margin expansion through additional utilization of our manufacturing locations in Mexico and Brazil, as well as through material cost reductions. We are actively working initiatives in each of these areas. "In Communications, we are currently experiencing a significantly higher level of proposal activity for investor-owned utilities. We are focused not only on delivering best value solutions for the opportunities in process, but also on enhancing and expanding our product offering through both internal development and acquisitions. In the AMR space, we continue to actively pursue acquisitions but progress to date has been limited. I believe this is, in part, - more - Add Six because the potential sellers may be reluctant to act until they understand the outcome of the significant, pending opportunities. With or without near-term acquisitions, we continue to have very substantial long-term prospects for growth within the AMR market. "From an opportunities standpoint, the Test business fits somewhere between Filtration and Communications. While there are size limitations within our served market, we continue to capitalize on our strong market position and to expand the foothold we have established in Asia. On the cost side, we have made substantial progress on a near-term initiative to reduce our material costs. We are also working on acquisitions which would increase our product content on significant test and shielding projects. "I continue to believe our shareholders will be well-served by the combination of our growth opportunities and initiatives and our end market diversification." Fiscal 2005 Business Outlook - ---------------------------- Statements contained in the preceding and following paragraphs are based on current expectations. Statements that are not strictly historical are considered forward-looking, and actual results may differ materially. 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 balance of the fiscal year. Revenues - -------- Management currently expects fiscal 2005 year-over-year revenue in Filtration to be essentially flat due to continued weakness in the automotive sector, which is down from the previous expectation of sales growth in the range of 2 to 5 percent. In Test, Management now expects revenue growth of 8 to 10 percent, an increase from the previous guidance of 4 to 8 percent. In Communications, Management continues to expect revenue to be flat to down 3 - more -

Add Seven percent. The expected flatness 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 in fiscal 2004. EBIT Margin - ----------- Management expects EBIT margins to be in the following ranges, which are consistent with previous guidance: 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 currently estimates fiscal 2005 EPS to be in the range of $3.10 to $3.20 per share, which is increased from the previous guidance of $2.95 to $3.15 per share. The current expectations on a quarterly basis for the remainder of 2005 are that the fourth quarter EPS will be higher than the third quarter EPS as a result of a more favorable sales mix. The effective tax rate for fiscal 2005 is expected to be approximately 37.5 percent, a slight improvement from the previous expectation of 38 percent. Conference Call - --------------- The Company will host a conference call today, May 10, at 9:30 a.m., Central Time, to discuss the Company's second quarter operating results. A live audio webcast will be available on the Company's Web site at www.escotechnologies.com. Please access the Web site at least 15 minutes prior to the call to register, download and install any necessary audio software. A replay of the conference call will be available for seven days on the Company's website noted above or by phone (dial 1-888-203-1112 and enter the pass code 1523374). - more -

Add Eight Forward-Looking Statements - -------------------------- Statements in this press release regarding future revenues and the level of revenue contributions from each segment, potential acquisitions, potential customer contracts, growth in the AMR market, the success of cost reduction efforts, fiscal 2005 corporate operating expenses, the fiscal 2005 effective tax rate, future fiscal 2005 results, earnings, fiscal 2006 and beyond revenue growth, EBIT margins, EPS, 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. 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; 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; material changes in the costs of certain raw materials including steel, copper and petroleum based resins; delivery delays or defaults by customers; termination for convenience of customer contracts; timing and magnitude of future contract awards; performance issues with key customers, 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. - more -
