Item 1.02 Termination of a Material Definitive Agreement.

Pursuant to the Equipment Supply Agreement dated February 7, 2017, as amended ("Supply Agreement"), between Aqua Metals, Inc. ("Company") and Clarios, LLC, a Wisconsin limited liability company formerly known as Johnson Controls Battery Group, Inc.
