In March 2023, the Company entered into agreements to acquire the existing facility and the installed industrial utility equipment in order to accelerate the first commercial scale implementation of its internally-developed first-of-kind lithium-ion battery recycling technologies. On August 25, 2023, the Company and Bow River Capital RE III LLC (“Bow River”) terminated the previously-announced contingent sales-leaseback arrangement, pursuant to which the Company would have sold certain real property to Bow River, while leasing the same property from Bow River and retaining an option to repurchase the property.

To date, $25 million has been received. Buyers may request partial redemptions of up to an aggregate of $1,800,000 on the 15^th of each month or may convert the Notes into shares of common stock of the Company (“Conversion Shares”) at a conversion rate of 110% of the last reported sales price on the date of the agreement to acquire such Notes. The Notes bear zero coupon, mature on September 1, 2025, and are secured by certain real property and cash and investment accounts of the Company.

On September 1, 2023, the Company finalized its grant award agreement with the U.S. Department of Energy (DOE) marking the official launch of the multi-year grant aimed at providing a domestic source of battery-grade lithium hydroxide. The Project kick off marks a major milestone in the commercialization of the Company’s Tonopah Flats Lithium Project, which will help provide a domestic supply of critical battery materials needed for the U.S. energy transition. On September 11, 2023, in preparation for listing on the Nasdaq Capital Market, the Company implemented a one-for-fifteen (1-for-15) reverse split of our common stock. Prior to the reverse stock split the Company had 692,068,218 shares of common stock issued and outstanding, and after the reverse stock split, the Company had approximately 46,137,882 shares of common stock issued and outstanding. Immediately after the reverse stock split, each stockholder’s percentage ownership interest in the Company and proportional voting power remained unchanged aside from rounding fractional shares into whole shares.
