                    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.

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.

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.

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 -

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.

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.
