Today,  August 7, 2007, the Registrant is issuing a press release  (Exhibit 99.1
to this report)  announcing  its fiscal year 2007 third  quarter  financial  and
operating results. See Item 7.01, Regulation FD Disclosure below.


Today, the Registrant is issuing a press release announcing its fiscal year 2007
third  quarter  financial  and  operating  results,  and will  conduct a related
Webcast  conference  call at 4:00 p.m.  central  time.  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.


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" and "Test segment EBIT-Operational".

The  Registrant  defines  "EBIT" as  earnings  before  interest  and taxes.  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  "Test segment  EBIT-Operational"  as Test segment EBIT
excluding the costs related to the adverse  arbitration  judgment and associated
legal costs involving a dispute over a 2005 U.S. government project.

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.
