Johnson Controls and Aqua Metals Agree to Extend Timelines on Strategic Licensing Agreement

ALAMEDA, Calif., April 26, 2018 (GLOBE NEWSWIRE) -- Aqua Metals, Inc. (NASDAQ:AQMS), (“Aqua Metals” or the “Company”), which is commercializing a non-polluting electrochemical lead recycling technology called AquaRefining™, has reached an agreement with Johnson Controls to extend the timelines of their Equipment Supply Agreement by one year.

On February 7, 2017, Aqua Metals entered into an Equipment Supply Agreement with a wholly-owned, indirect subsidiary of Johnson Controls International plc, or Johnson Controls, pursuant to which Aqua Metals agreed to collaborate on the development of a program for the installation of new greenfield builds, as well as conversion of existing Johnson Controls’—and certain strategic partners of Johnson Controls existing lead smelters—to a lead recycling process utilizing the Company’s proprietary and patented AquaRefining technology and equipment, know-how and services.

According to the terms of the agreement, both Parties agreed to use their good faith and commercial best-efforts to conclude their discussion and negotiation of the Development Program no later than April 30, 2018, and to enter into, no later than June 30, 2018, the Development Program.

At this time, both Johnson Controls and Aqua Metals have agreed to extend this period of discussion and negotiation by one year for each deadline respectively. Effective immediately, the date to conclude negotiation and discussion on the Development Program will now be no later than April 30, 2019 and the date to enter into the Development Program no later than June 30, 2019.

“We look forward to concluding discussions and beginning the installation of AquaRefining technology before these new dates,” said Selwyn Mould, interim Chief Executive Officer and Chief Operations Officer. “We appreciate Johnson Control’s flexibility in this matter. They continue to be an important strategic partner for Aqua Metals, lending their technical expertise in support of our mutual goals.”
