ITEM 2.02.  RESULTS OF OPERATIONS AND FINANCIAL CONDITION

Today,  August 9, 2005, the Registrant is issuing a press release  (Exhibit 99.1
to this report) announcing its fiscal 2005 third quarter financial and operating

Registrant's common stock. 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
third quarter  financial and operating  results and also the  declaration by its
Board of a  two-for-one  split of the  Registrant's  common  stock.  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  recorded in fiscal 2004,  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'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  from
continuing  operations  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  from  continuing  operations  less  capital
expenditures from 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
investor'   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.
