ITEM 2.02         RESULTS OF OPERATIONS AND FINANCIAL CONDITION

Today,  May 6,  2008,  the  Registrant  is  issuing a press  release  (furnished
herewith as Exhibit 99.1 to this report)  announcing its fiscal year 2008 second
quarter financial and operating results. See Item 7.01, Regulation FD Disclosure
below.


ITEM 7.01        REGULATION FD DISCLOSURE

Today,  the Registrant is issuing (i) a press release  (Exhibit 99.1) announcing
its fiscal year 2008 second quarter financial and operating results,  and (ii) a
second press release  (Exhibit 99.2)  announcing  that in April 2008 Pacific Gas
and Electric  Company (PG&E) placed  follow-on orders totaling $11.1 million for
additional  Aclara  advanced  metering   infrastructure   (AMI)  products.   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  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 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 expected 2008 "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 press  release  refers to expected  2008  "EPS-Adjusted  Basis" and EPS from
continuing   operations   adjusted  for  "software   and  purchase   accounting
amortization" exclusive of pre-tax intangible asset amortization expense related
to TWACS NG software,  purchase  accounting  intangible  assets  related to the
Registrant's  recent  acquisitions  and  the  expense  related  to the  purchase
accounting  step-up  of Doble  Engineering  Company  inventory.  The  Registrant
believes that the presentation of these operational  measures provides important
supplemental  information to 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 8.01         Other Events

Today, the Registrant is issuing a second press release  (furnished  herewith as
Exhibit 99.2 to this report) announcing that in April 2008 PG&E placed follow-on
orders totaling $11.1 million for additional Aclara AMI products. See Item 7.01,
Regulation FD Disclosure above.
