Plexus Provides Preliminary Fiscal Third Quarter 2015 Results

NEENAH, WI - July 13, 2015 - Plexus (NASDAQ: PLXS) today announced preliminary results for its fiscal third quarter ended July 4, 2015.

Plexus expects to report fiscal third quarter revenue of approximately $670 million and diluted earnings per share in the range of $0.67 to $0.70, compared to its previously announced revenue guidance of $670 to $700 million with diluted earnings per share of $0.71 to $0.79.

Dean Foate, Chairman, President and CEO, commented, “Our preliminary results are a consequence of unanticipated challenges we faced during the quarter. The most significant issue affecting the quarter was a production process constraint in one of our Defense/Security/Aerospace focus factories that limited our ability to complete product shipments late in the quarter. Further, in the final weeks of the quarter customer demand softened in our Networking/Communications sector resulting in forecast decommitments while our Healthcare/Life Sciences sector demand was weaker than our already projected soft expectations.”

These results are preliminary and represent the most current information available to management. The Company’s actual results may differ due to the completion of the Company’s fiscal third quarter financial closing and review procedures. As previously announced, the Company will report final results on July 22, 2015 and will host a conference call on July 23, 2015 at 8:30 a.m. Eastern Time to discuss these results.
