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

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.

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.

                    ESCO ANNOUNCES THIRD QUARTER RESULTS AND
                      RAISES FISCAL YEAR EARNINGS GUIDANCE


     St. Louis, MO, August 10, 2004 - ESCO  Technologies  Inc. (NYSE: ESE) today
announced its results for the fiscal 2004 third quarter ended June 30, 2004.

     The results  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  related to the exit and  relocation  of  Filtertek's
Puerto Rican manufacturing  facility; the 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; 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.

     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.

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 -

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

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.
