ITEM 2.02         RESULTS OF OPERATIONS AND FINANCIAL CONDITION

Today,  May 8, 2007, the Registrant is issuing a press release  (Exhibit 99.1 to
this  report)  announcing  its fiscal year 2007  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 a press release announcing its fiscal year 2007
second  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.

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" and
"EBIT margin".

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  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.

                     ESCO ANNOUNCES SECOND QUARTER RESULTS

     St.  Louis,  MO, May 8, 2007 - ESCO  Technologies  Inc.  (NYSE:  ESE) today
announced  its results for the second  quarter  ended March 31,  2007,  and also
reaffirmed  full year  earnings  per share (EPS)  guidance of $1.50 to $1.65 per
share.

     Within this release,  references to "quarters" and "year-to-date" relate to
the fiscal  quarters  and six month  periods  ended March 31 for the  respective
fiscal years noted.

     Net earnings for the 2007 second  quarter were $9.6  million,  or $0.36 per
share  compared  to net  earnings  of $7.3  million,  or $0.28 per share for the
second  quarter of 2006.  The 2007 second  quarter net earnings  included a $2.2
million research tax credit,  which favorably impacted net earnings by $0.08 per
share.

     Net earnings for the six months of fiscal 2007 were $8.2 million,  or $0.31
per share  compared  to $9.5  million,  or $0.36 per share for the first half of
2006.

Sales

     Second quarter 2007 sales were $129.1  million,  or 5.0 percent higher than
second quarter 2006 sales of $122.9 million. Favorable foreign currency exchange
rates in the 2007 second quarter resulted in $1.3 million of this increase.

     Fiscal 2007 year-to-date  sales were $227.9 million,  or 6.7 percent higher
than the  $213.5 million  of sales in the 2006  year-to-date  period.  Favorable
foreign currency exchange rates in the first six months of 2007 resulted in $2.4
million of increased sales.

     Communications  sales of $49.2  million  increased  $6.0  million,  or 13.9
percent in the 2007  second  quarter  compared  to the  second  quarter of 2006,
primarily due to $8.1 million of additional sales at Hexagram,  partially offset
by a $2.9  million  decrease  in  sales  at  DCSI.  Hexagram's  sales  increased
significantly  in the second  quarter due to the  ramp-up of  advanced  metering
projects in Kansas City and at PG&E.  DCSI's sales  decreased in the 2007 second
quarter  due to lower  sales to TXU and PREPA,  partially  offset by  additional
sales to Duke Energy and Florida Power & Light. In the 2007 second quarter, DCSI
sales to COOP and public power (Municipal) customers were $23.7 million compared
to $20.5 million in the second quarter of 2006. Year-to-date 2007 Communications
sales increased $16.9 million, or 27.1 percent compared to 2006 primarily due to
the  acquisitions of Hexagram and Nexus,  both of which had increased sales on a
monthly basis in 2007 compared to 2006.

     Filtration  sales of $45.9 million  increased $0.9 million,  or 2.0 percent
during the second  quarter of 2007 as  compared to 2006,  primarily  driven by a
$1.4 million increase in commercial  aerospace sales at PTI, partially offset by
lower  automotive  sales  at  Filtertek.   Year-to-date  Filtration  sales  were
consistent in 2007 compared to 2006, with PTI's sales  increasing  $2.3 million,
or 10.3 percent,  reflecting the continued strength of the commercial  aerospace
market,  and VACCO and Filtertek both having sales decreases due to lower demand
in the defense spares and automotive end markets, respectively.

     Test segment sales of $34.0 million decreased $0.6 million, or 1.7 percent,
during the second  quarter of 2007 compared to 2006, and  year-to-date  sales of
$62.2  million,  decreased  $2.4  million,  or 3.7 percent  from 2006 due to the
timing of installations described in the February 5, 2007 earnings release.

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 second quarter of fiscal 2007 included the
following.

     In the  Communications  segment,  EBIT for the 2007 second quarter was $6.1
million  (12.4  percent of sales),  compared to $9.7  million  (22.5  percent of
sales) in the 2006  second  quarter.  The  primary  factors of the $3.6  million
decrease  in EBIT  dollars  in 2007  include  a  $4.6 million  decrease  at DCSI
resulting  from  the  lower  sales  noted  above,   TNG  software   amortization
(incrementally  higher by $1.5  million  in the 2007  second  quarter)  and PG&E
related  program  support  costs.  EBIT  at the  other  operating  units  within
Communications  increased  $1.0 million as a result of additional  sales volume.
The 2007 year-to-date Communications segment EBIT of $3.3 million decreased $5.5
million  compared  to 2006  due to TNG  amortization  in  2007  of $2.7  million
compared  to $0.3  million  in 2006,  lower  sales in 2007 and  additional  PG&E
program support costs.

     In the  Filtration  segment,  the 2007 second quarter EBIT was $6.4 million
(13.9 percent of sales)  compared to $4.7 million (10.4 percent of sales) in the
prior year second quarter. The $1.7 million  increase in EBIT was due to: a $1.0
million increase at PTI related to an increase in commercial  aerospace sales; a
$0.8 million  increase at VACCO due to an improved  sales mix  resulting in more
favorable  overhead  absorption;  partially offset by a $0.2 million decrease at
Filtertek resulting from the decrease in domestic automotive sales. Year-to-date
Filtration  EBIT of $8.2 million  decreased $0.6 million  primarily due to lower
sales  at  VACCO  and  Filtertek,   partially   offset  by  the  increased  EBIT
contribution at PTI related to the sales increase.

     In the Test  segment,  EBIT was $4.1 million (12.1 percent of sales) in the
second quarter of 2007 compared to $4.3 million (12.4 percent of sales) in 2006,
and 2007 year-to-date  EBIT was $6.2 million compared to $7.3 million.  The 2007
EBIT  decreases  are  primarily  due  to  the  timing  of  installations  and an
additional $1.5 million of year-to-date  SG&A costs.  Corporate  operating costs
included in EBIT were $1.8 million higher in the second quarter of 2007 compared
to 2006 as the prior year  amount  included a $1.8  million  pretax  gain from a
previously  divested defense  subsidiary.  The Corporate 2007 year-to-date costs
are $3.2  million  higher due to the  absence of the $1.8  million  gain in 2006
noted  above,  higher  purchase  accounting  amortization,  higher  stock option
expenses and tax related professional fees.

Effective Tax Rate

     The effective  tax rate in the second  quarter of 2007 was 20.0 percent and
included  $2.2 million of additional research tax credits. This credit favorably
impacted the 2007 second quarter tax rate by approximately 19 percent.  The 2006
second quarter effective tax rate was 53.5 percent resulting from a $1.7 million
charge related to foreign cash repatriation.

New Orders

     New orders received in the 2007 second quarter were $135.8 million compared
to $128.7 million received in the 2006 second quarter.

     Backlog at March 31, 2007 was $307.7  million,  which has  increased  $54.2
million  since the  beginning  of the fiscal  year and $6.7  million  during the
second quarter.

     New orders  received in the second  quarter of 2007  compared to the second
quarter of 2006,  respectively,  were:  in  Filtration,  $54.7 million and $43.2
million; in Communications,  $44.4 million and $55.5 million (including the $6.0
million of Hexagram  acquired  backlog);  and in Test,  $36.7  million and $30.0
million.

Cash

     At March 31,  2007,  the  Company  had $28.0  million  in cash and no debt,
compared to $36.8  million in cash and no debt at September  30, 2006.  The $8.8
million  decrease in cash in the first six months of 2007 reflects $15.3 million
spent on  software  upgrades  (primarily  TNG),  $7.2  million  spent on capital
equipment,  and $1.3 million of  additional  payments  (earn out) related to the
Hexagram acquisition.

Chairman's Commentary - 2007 Second Quarter

     Vic  Richey,   Chairman  and  Chief  Executive  Officer,   commented,   "As
anticipated,  our second quarter operating  results rebounded  strongly from our
first quarter performance and significantly  exceeded our internal expectations.
While all three segments contributed to the  better-than-expected  earnings, the
most  significant   contributions  came  from  the  Filtration  segment  and  in
particular, the aerospace businesses at PTI and VACCO.

     "Our consolidated  second quarter entered orders remained strong as we grew
our backlog  again during the quarter.  Together  with the strength of the first
quarter orders,  our six month  consolidated  book-to-bill  ratio is 124 percent
with all segments in excess of 100 percent.  Our year-to-date  order performance
supports the significant growth we anticipate for the remainder of the year.

     "Although we continue to expect  strong second half  performance,  our full
year outlook in the Communications segment is down due to two water AMR projects
beginning their deployments later in 2007 than previously expected. These delays
are  partially  offset by  improved  operating  performance  from our  aerospace
businesses,  and given the  improvement in our estimated full year tax rate, our
EPS guidance is unchanged.

     "While our operating  management  remains squarely focused on delivering on
our second half commitments,  we are also continuing to fully support the growth
initiatives necessary to meet our longer term objectives."

Business Outlook

     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  does not  include  the  impact of
potential  acquisitions or  divestitures,  but does include the  amortization of
identifiable  intangible  assets  related to Nexus and Hexagram,  as well as the
amortization of the TNG software.

     Additionally,  refer  to the  "Business  Outlook  -  2007"  section  of the
November 14, 2006 earnings  release for a comprehensive  discussion of "Purchase
Accounting - Identifiable  Intangible Assets," "TNG Software  Amortization," and
the "PG&E Contract."

     The 2007 revenue and EPS estimates  described  below include  approximately
$20  million of sales and  approximately  $8  million of EBIT  related to DCSI's
portion of the PG&E contract which is subject to revenue deferral until delivery
of TNG  version  3.0  is  achieved.  Version  3.0 is  currently  expected  to be
delivered  in the fourth  quarter  of fiscal  2007,  at which  time the  Company
expects to recognize the cumulative  deferred  revenue on the units delivered up
to that date.

     The November 14, 2006 earnings release also contains  Management's "Fiscal
2008  Preliminary  Long-Term  Outlook" and  "Chairman's  Commentary  on Business
Outlook."

Earnings Per Share - 2007

     Management  estimates  of 2007 EPS  continue to be in the range of $1.50 to
$1.65  per  share,   which  includes   approximately   $9.0  million  of  pretax
amortization  expense,  or $0.21  per  share,  related  to  purchase  accounting
intangible assets and TNG software.

     The 2007  second  half EPS is expected to be in the range of $1.19 to $1.34
per share. Stock option expense for 2007, which is included in the EPS guidance,
is still  expected  to be in the range of $0.10 to $0.12 per share,  or $0.03 to
$0.04 per quarter.

     The  effective  tax rate for the second  half of fiscal 2007 is expected to
remain at 39 percent.  Due to the tax research credits  favorably  impacting the
tax rate in the first  half of the year,  the total year  effective  tax rate is
estimated to be approximately 35 percent.

Revenues and EBIT Margins - 2007

     Management expects 2007 consolidated revenues to increase  approximately 22
percent  compared to 2006 and be in the range of $555 to $560  million,  and the
consolidated  EBIT  margins  should  be in  the  range  of 11  to  11.5  percent
(including the impact of the amortization of identifiable  intangible assets and
the TNG amortization).

     On a segment and operating unit basis for 2007,  Management now expects the
following (as compared to the February 5, 2007 Business Outlook):

o    PTI sales are now expected to increase approximately 17 percent (versus 4.5
     percent)  and should be between  $54 and $55  million  (versus  $48 and $49
     million)  and EBIT  margins  should be in the  range of 18 to 18.5  percent
     (versus  15 to  15.5  percent)  based  on  the  continued  strength  of the
     commercial aerospace business.

o    VACCO's sales are now expected to increase approximately 12.5 to 13 percent
     (versus 8 percent)  and should be between $36 and $37  million  (versus $35
     and  $36 million)  with  EBIT  margins  remaining  in the range of 18 to 19
     percent as the sales mix changes  between defense spares and space products
     compared to 2006.

o    Filtertek  sales are now expected to increase  approximately 6 to 7 percent
     (versus 7 to 9 percent) and be in the range of $100 to $102 million (versus
     $102 to $104  million)  with  EBIT  margins  now in the range of 6.5 to 7.5
     percent (versus 7 to 8 percent).

o    The Test  segment  sales  now are  expected  to  increase  8.5 to 9 percent
     (versus  7.5 to 8.5  percent)  and be in the range of $139 to $141  million
     (versus $138 and $140 million) with EBIT margins  remaining in the range of
     12 to 12.5 percent.

o    The Communications segment sales are now expected to increase approximately
     46 to 48 percent  (versus 48 to 50 percent)  and be in the range of $227 to
     $230 million  (versus $231 to $234  million) and EBIT margins  should be in
     the range of 17 to 19 percent (versus 18 to 20 percent).  These changes are
     the result of a more refined delivery  schedule from PG&E and two water AMR
     contracts starting their 2007 deployments later in the year than previously
     expected.  Nexus  sales are now  expected  to be in the range of $15 to $16
     million  (versus $16 to $18 million) and EBIT margins  should now be in the
     range of 5 to 6 percent  (versus 6 to 7  percent).  Hexagram  sales are now
     expected  to be in the  range  of $57 to  $59  million  (versus  $60 to $63
     million)  and EBIT  margins are now expected to be in the range of 18 to 20
     percent  (versus 22 to 24  percent).  Sales of AMR  products at DCSI remain
     unchanged  and are expected to be in the range of $144 to $147 million with
     EBIT margin  expectations  remaining  at  approximately  20 percent,  which
     includes approximately $7.0 million of TNG amortization costs. At March 31,
     2007, the Company had approximately $48 million in external TNG development
     costs capitalized on the balance sheet in other assets,  and is expected to
     incur another $10 million in costs over the next year.  Additional  non-TNG
     related  engineering  and  development  costs are being  expensed as period
     costs.

o    Corporate  operating cost expectations for 2007 remain at approximately $18
     million and include $2.1  million of pretax  amortization  of  identifiable
     intangible assets related to Nexus and Hexagram.
