Dear Mr. Migone:

This letter confirms our conversation from earlier today. In that exchange, I stated that Plexus Corp. would respond to the Staff’s comments included in the letter from Craig D. Wilson, dated April 25, 2016, by May 23, 2016.

If we have any specific questions as we draft our response, we will contact you. In addition, please let me know if you have any questions of us.

Very truly yours,
