Overview

Plexus Corporation is an American contract manufacturer of electronic assemblies and devices, operating a pure electronics manufacturing services (EMS) business model. Founded in 1979 in Wisconsin, the company was built around the idea of combining development and design services with manufacturing services. It serves sectors including network technology, wireless networks, medical technology, defense technology and aerospace safety technology. Its corporate headquarters is in Neenah, Wisconsin, and it maintains manufacturing and sales locations in North America, Mexico, Germany, Scotland, Romania, China and Malaysia. Plexus does not sell products under its own brand name. All products are developed and produced exclusively on behalf of OEM customers, which means there are no products bearing the Plexus brand. The company positions itself as the "Product Realization Company," offering product development, manufacturing optimization, new product introduction for series production including prototyping, series manufacturing, logistics, repair and after-sales services. It focuses on telecommunications, industrial, medical technology and aerospace including military technology, with small to medium production volumes. Plexus went public in 1986 with annual revenue of 24 million US dollars. By 1997 it had reached annual revenue of 400 million US dollars. In the following years, like the entire EMS industry, Plexus benefited strongly from the dot-com bubble and continued to grow. After the internet bubble burst, the company had to absorb a sharp decline in revenue, which led to extensive restructuring measures. Today Plexus is a global company with locations in the Americas, Europe and Asia. It employs around 8,000 people and generated annual revenue of around 4.2 billion US dollars in 2023. In Germany, Plexus is represented in Darmstadt with around 80 employees.
