Plexus Corp was incorporated in 1979 as a Wisconsin corporation. The Company and its subsidiaries participate in the Electronic Manufacturing Services industry. It delivers optimized Product Realization solutions through a Product Realization Value Stream services model. This customer focused services model seamlessly integrates product conceptualization, design, commercialization, manufacturing, fulfillment and sustaining services to deliver comprehensive end-to-end solutions for customers in the Americas, European and Asia-Pacific regions. Customer service is provided to over 140 branded product companies in the Wireline/Networking, Wireless Infrastructure, Medical, Industrial/Commercial and Defense/Security/Aerospace market sectors. Its customers' products typically require exceptional production and supply-chain flexibility, necessitating an optimized demand-pull-based manufacturing and supply chain solution across an integrated platform. Many of its customers' products require complex configuration management and direct order fulfillment to their customers internationally. In such cases it provides logistics management and after-market service and repair. The Company offers its customers the ability to outsource all phases of product realization, including product specifications; development, design and design verification; regulatory compliance support; prototyping and new product introduction; manufacturing test equipment development; materials sourcing, procurement and supply-chain management; product assembly/manufacturing, configuration and test; order fulfillment, logistics and service/repair. It operates flexible manufacturing facilities and processes designed to accommodate customers with multiple product-lines and configurations. It provides its contract manufacturing services on a turnkey basis, which means that it procures some or all of the materials required for product assembly. The Company provides some services on a consignment basis, which means that the customer supplies the necessary materials, and it provides the labor and other services required for product assembly. Turnkey services require material procurement and warehousing, in addition to manufacturing, and involve greater resource investments than consignment services. The Company is subject to a variety of environmental regulations relating to air emission standards and the use, storage, discharge and disposal of hazardous chemicals used during its manufacturing process.
