Dear Valued Customer,

We are writing to inform you of an important update on how we handle support, purchase order (PO),
and return material authorization (RMA) inquiries, effective June 1, 2025.

To streamline communication and ensure timely and effective responses, we kindly ask that all future
inquiries be sent to the appropriate centralized email address:

POs:
PO@coolitsystems.com
RMAs:
RMA.Coolit@coolitsystems.com
General Support:
Support@coolitsystems.com

We will do our best to accommodate messages sent to individual email addresses, but we cannot
guarantee they will be acknowledged or processed after June 1, 2025.

This change will help us improve response times, enhance service quality, and ensure consistent
handling of your requests. Customers using internal systems or portals to submit inquiries may
continue to do so as usual. Please note that these email addresses will not respond to supplier and partnership requests.

If you have any questions or need further assistance, please don’t hesitate to reach out to your
Account Manager or a member of our team.

Thank you for your understanding and continued partnership.
