To our valued global customers and supply chain providers…

As we navigate through these challenging times, I wanted to reaffirm that GTAT is operating to meet its commercial obligations to you. Our production lines are running and we are following all health and government mandates and protocols. These include appropriate social distancing for necessary employees at our facilities, and enhanced cleaning and sanitizing measures. All GTAT employees able to work remotely are doing so, and they have access to everything needed to maintain normal operations throughout this global health emergency.

We wish all of our customers and providers the very best. We will get through this together.

Sincerely,
Greg Knight, President and Chief Executive Officer
GTAT Corporation
