PLEXUS COMPLETES FIRST ANNUAL B.E.S.T. COMPETITION

NEENAH, WI, February, 11 2015 - Plexus Corp. (NASDAQ: PLXS), today announced the successful completion of its first annual Bringing Employee Successes Together (B.E.S.T.) competition. The event is part of a global continuous improvement initiative at Plexus to share best practices across the organization in a fun way that engages employees. As a result of the 2014 competition, $8,000 was donated to charities all over the world.

Plexus is committed to promoting a culture of employee engagement, collaboration and learning. The B.E.S.T. initiative provides a vehicle for our teams to share the innovative ways that they've solved problems for our customers and makes this information widely available across the enterprise, thus helping to avoid 'reinventing' the wheel.

"The concept of "best practice" asserts that there is a proven process that is more effective at delivering a particular outcome than any other," explains Ronnie Darroch, Senior Vice President of Global Manufacturing Solutions. "The goal of the initiative is to find these pockets of greatness and implement them globally."

Todd Kelsey, Executive Vice President and Chief Operating Officer, commented, "The B.E.S.T. initiative provides a way for us to standardize core processes across our facilities while establishing a system for sharing best practices. This will allow us to build a culture focused on collaboration and innovation, which will assist us in achieving Operational Excellence."

Competition winners were selected at a site and regional level, with the winning team from each region advancing to a global competition held at Plexus' Global Headquarters in Neenah, Wis. The participants from each global finalist team received rewards and recognition for their accomplishments.

Each global finalist team made donations to a local charity of their choosing, which included:

• Merit School of Music in Chicago, Ill.
• Scottish Association for Mental Health in Glasgow, Scotland
• Down Association Oradea in Oradea, Romania
• Order of our Lady of Charity in Juarez, Mexico
• Education Fund of Xiamen in Xiamen, China
• Penang Cheshire Home in Penang, Malaysia

Plans are currently underway to implement the winning project across all Plexus manufacturing facilities, saving valuable time and millions of dollars.
