Forward - Looking Statement

ST. PETERSBURG, FL – March 31, 2006 – Jabil Circuit, Inc. (NYSE:JBL) today announced that its facility in Singapore has been granted Federal Aviation Administration (FAA) repair station status. Singapore is the second Jabil facility to become certified to provide repair and support services on products utilized in commercial aircraft. Earlier this year, Jabil announced the certification of its Billerica, Massachusetts facilities by the FAA.

“Our Singapore facility offers ultra-high mix, low volume AS9100 certified manufacturing and can now support the entire aerospace product life-cycle,” said Jim Cocke, Senior Director of Jabil’s Defense and Aerospace Services business unit. “Having a partner such as Jabil enhances our customer’s ability to provide timely technology insertions on legacy products and increase their competitive edge.”

Traditionally aerospace companies have not utilized external manufacturing providers, however many have begun to utilize partners such as Jabil, who offer global aerospace manufacturing and support services, according to Cocke.

“Certifying this facility for aerospace life-cycle support activities is another milestone in our aerospace-industry growth strategy. Our aerospace customers in Asia will benefit from the expansion of our repair station services,” he said.

The Jabil - Singapore Repair Station holds Certificate J0BY513Y. The Jabil - Billerica repair station holds certificate # J1IR247Y.
