ESCO Announces AMR Pilot Update

ST. LOUIS, Aug. 22 /PRNewswire-FirstCall/ -- ESCO Technologies Inc. (NYSE: ESE) today provided an update on a previously discussed advanced metering opportunity with a customer located in the southern United States. During the Company's investor conference call on August 8, 2006, Management discussed several advanced metering opportunities in which the Company is participating and described one particular latter-stage pilot as having a near-term project approval expectation.

Based on ongoing discussions with the customer of this latter-stage pilot, project approval was expected to be received prior to September 30, 2006 and deployment was expected to begin in the second half of fiscal 2007. The customer informed Management that they would be delaying their decision to move forward with the project for at least a year. The customer indicated that the TWACS(R) system met their core requirements and that they were continuing their evaluation.

We will continue to support this customer on this project.
