                      ESCO PRE-ANNOUNCES FOURTH QUARTER AND
                          FISCAL YEAR 2008 EXPECTED EPS


     ST. LOUIS,  October 21, 2008 - ESCO  Technologies  Inc.  (NYSE:  ESE) today
pre-announced  its expected results for the fourth quarter and fiscal year ended
September 30, 2008.

     Management  expects  its fiscal  2008 fourth  quarter  EPS-GAAP  Continuing
Operations  to be at least $0.76 per share,  which results in expected full year
EPS-GAAP  Continuing  Operations  to  be  at  least  $1.80.  These  amounts  are
consistent with the Company's EPS-GAAP  Continuing  Operations guidance of $1.80
to $1.85 per share noted in the Company's August 7, 2008 release.

     In addition,  Cash Flow from  Operations  and Entered  Orders both exceeded
Management's  previously announced expectations for the fourth quarter of fiscal
2008.

     The additional cash flow allowed the Company to further reduce its net debt
outstanding,  and the  increase  in entered  orders  positions  the  Company for
continued growth in fiscal 2009.

     The final EPS amounts are subject to the completion of the Company's fiscal
year end annual audit process.

     Management  will host its  regular  fourth  quarter  and  fiscal  year 2008
earnings  conference call and audio webcast on Wednesday,  November 12. Specific
webcast access details will be provided in a separate release.

     Vic Richey, ESCO's Chairman and Chief Executive Officer,  commented,  "I am
very pleased with our fourth quarter and full year results,  especially in light
of this  challenging  economic  environment.  ESCO continues to benefit from the
scale of our multi-segment  operating platforms,  the breadth of our product and
service  offerings,  ongoing  investments in new products and technologies,  the
diverse range of blue-chip  customers we serve, and ourfocus on rigorous project
execution and disciplined  cost  management.  Our strong and flexible  financial
foundation  gives ESCO a  recognizable  advantage  in both good and bad economic
times."
