NEENAH, Wis. (Map) - NEENAH, Wis., April 7, 2008 /PRNewswire-FirstCall/ -- Plexus Corp. (Nasdaq: PLXS) today announced that it has committed to two facility leases that will modestly expand its North American manufacturing footprint. Plexus' San Jose-area operation will relocate to a larger 46,000 sq ft facility located approximately eight miles from the existing facility. Plexus' Chicago-area operation will expand into a 48,000 sq ft facility adjacent to the existing facility, bringing the site's total footprint to 189,000 sq ft.

"Our facilities in North America are integral components of Plexus' global manufacturing and supply chain solution set, supporting our focus on mid-to-low-volume, mid-to-high-mix customer programs that require flexibility, agility and flawless execution," stated Mike Buseman, Sr. VP - Global Manufacturing Operations. "We believe that these strategic facility investments are vitally important to delivering a lowest total cost value proposition to our customers."

Plexus' San Jose-area facility will relocate from the existing 36,000 sq ft site to a larger facility with 46,000 sq ft. The newer and larger facility will accommodate better operational flow, an improved work environment and investments in manufacturing technology to better serve our customers in this geographically important market. Plexus' San Jose-area facility supports customers in all four of Plexus' sectors with significant expertise in the Wireline/Networking and Wireless Infrastructure sector. The site also serves as a new product introduction and production ramp facility for strategic growth customers.

Plexus' Chicago-area facility has seen increased demand from customers, particularly in the Medical sector. The additional 48,000 sq ft coupled with the current 141,000 sq ft will position the facility to support current customer demands and further growth in revenue for after market services, Configure to Order (CTO) and distribution services for North American end-customers. Plexus' Chicago-area facility is approved by the Food and Drug Administration (FDA) to manufacture finished class II and III medical devices.
