ITEM 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITION Today, August 4, 2009, the Registrant is issuing a press release (furnished herewith as Exhibit 99.1 to this report) announcing its fiscal year 2009 third 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 (Exhibit 99.1) announcing its fiscal year 2009 third quarter financial and operating results. The Registrant will conduct a related Webcast conference call today at 4:00 p.m. central time. This press release will be posted on the Registrant's web site located at http://www.escotechnologies.com. It can be viewed through the "Investor Relations" page of the web site 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 as Exhibit 99.1 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 EBIT, EBIT margin, "operational" EPS, USG segment "operational" EBIT, EPS-"Operational" Basis and EPS-Adjusted Basis. The Registrant defines EBIT as earnings before interest and taxes from continuing operations. The Registrant defines EBIT margin as EBIT as a percent of net sales. The Registrant's management evaluates the performance of its operating segments based on EBIT and EBIT margin, and believes that EBIT 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 is also one of the measures used by management in determining resource allocations within the Registrant and incentive compensation. The Registrant defines each of "operational" EPS and EPS-"Operational" Basis as EPS-GAAP exclusive of Aclara RF facility exit/relocation costs. The Registrant defines USG segment "operational" EBIT as Utility Solutions Group EBIT exclusive of Aclara RF facility exit/relocation costs. The Registrant defines EPS-Adjusted Basis as EPS-GAAP exclusive of pre-tax intangible asset amortization expense related to TWACS NG software, purchase accounting intangible asset amortization related to the Registrant's acquisitions within the past three years, the expense related to the purchase accounting step-up of Doble Engineering Company inventory, and the Aclara RF facility exit/relocation costs. The Registrant's management believes using "operational" EPS, USG segment "operational" EBIT, EPS-"Operational" Basis and EPS-Adjusted Basis as financial measures is important for management and investors to understand the Company's operations and its ability to service its debt. The Registrant believes that the presentation of these operational measures provides important supplemental information to management and investors regarding financial and business trends relating to the Registrant's financial condition and results of operations. The Registrant's management believes that these measures provide an alternative method for assessing the Registrant's expected future performance that is useful because they facilitate comparisons with other companies in the Utility Solutions Group segment industry, many of which use similar non-GAAP financial measures to supplement their GAAP results. The Registrant provides this information to investors to enable them to perform additional analyses of present and future operating performance, compare the Registrant to other companies, and evaluate the Registrant's ongoing financial operations. 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 (loss), cash flows, financial position, comprehensive income (loss), or any other measure as determined in accordance with GAAP. ITEM 9.01 FINANCIAL STATEMENTS AND EXHIBITS (d) Exhibits Exhibit No. Description of Exhibit 99.1 Press Release dated August 4, 2009 OTHER MATTERS The information in this report furnished pursuant to Item 2.02 and Item 7.01, including Exhibit 99.1, shall not be deemed to be "filed" for 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 incorporates it by reference into a filing under the Securities Act of 1933 as amended or the Exchange Act. 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 THIRD QUARTER RESULTS


     ST.  LOUIS,  August 4, 2009 - ESCO  Technologies  Inc.  (NYSE:  ESE)  today
announced its results for the third quarter ended June 30, 2009.

     Within this  release,  references to "quarters"  and  "year-to-date"  (YTD)
relate to the  fiscal  quarters  and  nine-month  periods  ended June 30 for the
respective fiscal years noted.

     Net  earnings  and EPS  are  presented  from  "Continuing  Operations"  and
"Discontinued  Operations."  Continuing  Operations represent the results of the
ongoing businesses of the Company. Discontinued Operations represent the results
of Comtrak which was sold in March 2009 and the filtration business of Filtertek
which was sold in November 2007 (first quarter fiscal 2008).

     The results  for the third  quarter  ended June 30,  2009  include a pretax
charge of $2.3 million,  or $0.07 per share after tax,  related to the Aclara RF
facility relocation which was completed in June. Management believes adding back
this cost to the  quarterly  earnings  results  ("operational"  basis) is a more
relevant  measure for investors to understand  the Company's  ongoing  operating
results for the current period.

     The third  quarter  effective tax rate  contributed  positively to both the
2009 and 2008  results of  operations,  and was 23.1 percent and 23.2 percent in
third  quarters of 2009 and 2008,  respectively.  The  favorable  rates were the
result of  approximately  $2 million in income tax benefits  realized in each of
the noted periods.

     The following  discussion of the 2009 results  compared to 2008 is based on
the "operational" amounts for 2009.

2009 vs. 2008 Highlights - Continuing Operations
- ------------------------------------------------

o    Third quarter 2009  "operational" EPS was $0.49 per share compared to $0.47
     per share in 2008, reflecting a 4.3 percent increase in the current period.
     GAAP EPS was $0.42 per share for the 2009 third quarter  reflecting  the RF
     facility relocation charges.

o    YTD  "operational"  EPS was $1.11 per share in 2009  compared  to $1.05 per
     share  in  2008.  The  2008  YTD EPS  amount  includes  a $0.20  per  share
     contribution  from  the  recognition  of the  PG&E /  TWACS  NG   software
     deferred revenue described below.

o    The  effective  tax rates in the third  quarters of 2009 and 2008 were both
     favorably  impacted  by  approximately  $2 million in income tax  benefits,
     resulting in comparable tax rates of 23.1 percent and 23.2 percent.

o    Sales decreased 2.1 percent in the third quarter, but increased 6.8 percent
     YTD.

o    Cash flow from  operating  activities  generated  $17.1 million  during the
     third quarter,  and $37 million YTD. As a result,  net debt outstanding was
     reduced to $165.4  million at June 30, 2009  reflecting a leverage ratio of
     1.92x.

o    Entered  orders  were $157.6  million in the third  quarter,  reflecting  a
     book-to-bill  ratio of 106  percent,  and YTD  entered  orders  were $453.8
     million, or 102 percent of YTD sales.

o    Orders in the third  quarter for Aclara RF AMI gas products  with PG&E were
     $18.1 million  bringing  total  gas  product  orders to  approximately  3.4
     million units and $193 million to date.

o    Orders for RF AMI products  with New York City Water were $13.3  million in
     the  quarter,  bringing  the total New York City  Water  project to 427,000
     units and $34.3 million to date.

o    Orders of Aclara  PLS AMI  products  in the 2009 third  quarter  were $46.9
     million, reflecting the highest quarterly order amount at PLS in two years.

o    Aclara PLS orders from COOP's and Muni's were $39.1 million in the quarter,
     and $69.3  million  YTD,  bringing  total YTD  Aclara  PLS  orders to $88.6
     million, including $5.4 million of load control / demand response devices.

Chairman's Commentary
- ---------------------

     Vic Richey, Chairman and Chief Executive Officer,  commented, "I am pleased
with our operating results during the quarter and year-to-date, especially given
today's  challenging global economy.  While several of our end markets continued
to see a push-out of product deliveries,  mainly commercial  aerospace and Doble
hardware, we were able to achieve the majority of our internal operating goals.

     "Our  Filtration  and Test  businesses  continue to maintain their focus on
appropriate  cost structures,  and we are extremely  confident that we will come
out the other side of this  unprecedented  downturn stronger and more profitable
than before.

     "Our Aclara  group  continues to see solid order  growth,  evidenced by the
positive book-to-bill ratio for the quarter and the year. While pleased with the
strong order book, we, like others in the AMI space, have experienced a push-out
of some  expected  orders  and  sales as a result  of the  Government's  planned
Stimulus  spending.  Several of our customers have told us that they are waiting
on placing  orders until they fully clarify  their  position with the DOE on how
and  when  to  effectively  proceed  with  their  infrastructure  spending.  The
customers' goal is to maximize the impact of the available grant money.

     "As a result,  while the  confidence  in our  longer-term  outlook  remains
bullish,  we believe  the  overall  impact of the  Stimulus  funding is having a
negative impact on the near term. We are actively  engaged in assisting  several
AMI customers in navigating through the grant process, and we are expecting that
once the administrative process is completed, we will benefit from this program.

     "While we continue to aggressively  manage our  operational  cost structure
through regular and detailed  planning  meetings with our Management  teams, the
uncertainties of today's macro environment and the delays caused by the Stimulus
program  are  causing  us to take a more  conservative  earnings  posture  as we
address the last two months of 2009. As a result, and as discussed later in this
release,  we are  adjusting our total year  expectations  to reflect this modest
level of uncertainty.

     "Despite  today's  economic  conditions,  we are  maintaining  our focus on
creating significant growth opportunities so that once the economy rebounds,  we
will be  best-positioned  to  capitalize on these  opportunities.  To ensure our
future growth,  we are maintaining our R&D and engineering  expenditures,  which
are directed  toward new product  development  initiatives  in the AMI and Smart
Grid area, along with a significant amount of new Space program opportunities. I
am confident that our new products  currently being  introduced will position us
well for the future.

     "In closing, we continue making meaningful progress on all of our major AMI
projects, including PG&E gas, New York City Water, and Idaho Power."

Sales
- -----

     For  2009,  sales  decreased  2.1  percent  during  the third  quarter  and
increased 6.8 percent for the first nine months  compared to the same periods of
2008. As noted in earlier  releases,  the prior year's YTD sales amount included
$20.5  million of revenues  recognized  that had  previously  been deferred from
prior periods related to PG&E / TWACS NG software revenue recognition. YTD sales
increased 12.3 percent excluding the 2008 PG&E deferred revenue recognized.

     Utility  Solutions  Group (USG) sales in 2009 increased 4.3 percent for the
third  quarter and 13.5 percent for the first nine months  compared to the third
quarter  and first  nine  months  of 2008,  respectively.  Absent  the TNG sales
deferral in 2008, YTD sales increased  24.1 percent from the prior year. The USG
sales increases in 2009 were primarily driven by significantly higher deliveries
of fixed network RF AMI products to PG&E (gas) and continued  increases in water
AMI  product  deliveries.  Additionally,  having  Doble for nine  months of 2009
versus seven  months in 2008  contributed  an  additional  $11.6  million of YTD
sales.

     Test  sales  in 2009  decreased  in the  third  quarter  and  YTD  periods,
primarily  due to the timing of large chamber  deliveries  to the  international
wireless and electronics end-markets.

     Filtration  sales in 2009  decreased in the third  quarter and YTD as sales
increases in the defense  aerospace and space product lines were offset by lower
commercial aerospace product deliveries.

Earnings Before Interest and Taxes (EBIT)
- -----------------------------------------

     On a segment basis,  items that impacted EBIT dollars and EBIT as a percent
of sales ("EBIT margin") during the third quarter and YTD periods of fiscal 2009
included the following:

     In the USG segment, "operational" EBIT for the 2009 third quarter was $15.5
million ($13.2 million on a GAAP basis) compared to 2008's third quarter EBIT of
$16.2 million. USG's EBIT was impacted by a significant sales increase of RF AMI
products,  offset by lower sales of PLS AMI  products  and lower Doble  hardware
sales.  The RF AMI business  contributed the largest increase to EBIT during the
first nine months of 2009.

     The 2009 YTD increase in USG's EBIT was partially mitigated by the 2008 YTD
EBIT  contribution  of $8.5 million  associated  with the PG&E deferred  revenue
recognized in the prior year first quarter.

     In the Test  segment,  EBIT  dollars and EBIT  margins  were  significantly
higher in 2009 due to favorable  changes in sales mix and rigorous cost controls
throughout the organization.

     In the  Filtration  segment,  EBIT  dollars  decreased in 2009 due to lower
sales of high margin commercial aerospace products,  an increase in research and
development costs and higher bid and proposal costs incurred in the pursuit of a
significant  number of Space  related  projects.  For the third quarter of 2009,
Filtration's  EBIT margin increased due to stringent cost management  across the
segment.

     Corporate  operating  costs in the third  quarter were lower in 2009 due to
reduced discretionary spending, partially offset by higher amortization expenses
related to recent acquisitions which included identifiable intangible assets.

Effective Tax Rate
- ------------------

     The effective tax rate from  Continuing  Operations in the third quarter of
2009 was 23.1 percent compared to 23.2 percent in the third quarter of 2008. The
2009 and 2008 third quarter tax rates were favorably  impacted by  approximately
$2 million of income tax benefits.  The 2009 YTD rate was 30.1 percent  compared
to 31.9  percent  and  was  also  favorably  impacted  by  income  tax  benefits
recognized.

New Orders
- ----------

     New orders  received  were $157.6  million  and $453.8  million in the 2009
third quarter and YTD periods, respectively,  reflecting a positive book-to-bill
in both the  quarter  and nine month  periods.  Backlog at June 30, 2009 grew to
$270.3 million compared to $266.1 million at the beginning of the fiscal year.

     Orders from PG&E for AMI gas  products and from New York City for AMI water
products  are  noted on page  one of this  release.  Orders-to-date  for the $25
million Idaho Power AMI project were $8.2 million.

Business Outlook - 2009
- -----------------------

     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  Business  Outlook  described  below  excludes the impact of any future
acquisitions  or  divestitures,  and reflects the impact of the  amortization of
identifiable  intangible  purchase accounting assets related to Aclara Software,
Aclara RF, Doble and LDIC; the impact of the Doble inventory  step-up  resulting
in "lost" profit; and the amortization of TWACS NG software.

Aclara RF Facility Relocation
- -----------------------------

     Due to the  significant  sales  growth  since  its  acquisition,  Aclara RF
Systems Inc.  (formerly  Hexagram,  Inc.)  relocated its  operations  from three
leased  facilities to a single,  newer,  more efficient  leased  facility in the
greater Cleveland area. As a result,  approximately  $2.3 million,  or $0.07 per
share,  of exit and relocation  costs were incurred during the fiscal 2009 third
quarter in the Utility  Solutions  Group.  These costs primarily  related to the
noncash write-off of leasehold improvements, vacant facility charges, and moving
costs.

Revenues and Earnings Per Share - 2009
- --------------------------------------

     Based on Management's current expectations,  the outlook for fiscal 2009 is
     as follows:

          o Revenues of approximately $625 million to $630 million;

          o EPS is expected to be in the following ranges:

               EPS - GAAP Continuing Operations             $ 1.82 to 1.87

               Add: Aclara RF Facility Exit / Relocation    $ 0.07    0.07
                                                            ------    ----

               EPS - "Operational" Basis                    $ 1.89 to 1.94
                                                            ======    ====

               Add: Intangible Amort. & Inventory Step-Up   $ 0.42    0.42
                                                            ------    ----

               EPS - "Adjusted" Basis                       $ 2.31 to 2.36
                                                            ======    ====

          EPS - Adjusted Basis excludes  approximately  $0.42 per share of costs
     related to TWACS NG software  amortization,  purchase accounting intangible
     asset amortization,  and Doble's purchase accounting  inventory step-up, as
     well as the  $0.07 per share of  Aclara  RF  facility  exit and  relocation
     costs.

          The  2009  full-year  tax  rate is  expected  to be  approximately  33
     percent,  consistent  with the full year tax rate of 33.3 percent for 2008.
     The favorable  rates are the result of  approximately  $2 million in income
     tax benefits realized in each of the years noted.

          Management  believes  using  EPS  -  "Operational"  Basis  and  EPS  -
     "Adjusted" Basis as financial measures is an important metric for investors
     to understand the Company's operations and its ability to service its debt.

Chairman's Commentary - Wrap-Up
- -------------------------------

          Mr.  Richey  concluded,  "As noted above,  while 2009 has been a tough
     year  as it  relates  to  today's  global  economic  challenges,  I  remain
     optimistic  about our current  business  prospects  both  domestically  and
     internationally.  Through rigorous  management  oversight and a disciplined
     planning process, I am confident that we have sufficient  opportunities and
     the appropriate contingencies in place to allow us to execute our strategic
     plan and to achieve our long-term goal of increasing shareholder value."
