Westwater Resources Announces Letter of Intent for Sale of Ultra-PMG™ Representing More than 25% of the Expected Annual Ultra-PMG™ Output from the Kellyton Plant

Graphite Sales Continuing Across All Product Lines

CENTENNIAL, Colo.--(BUSINESS WIRE)--Westwater Resources, Inc. (NYSE American: WWR), an energy technology and battery-grade natural graphite company (“Westwater Resources” or the “Company”), today announced that it has signed its first letter of intent (LOI) to sell Ultra-Purified Micronized Graphite (Ultra-PMG™) from our Kellyton Graphite Processing Plant, which is now under construction in east-central Alabama. As is standard, the LOI is subject to customary conditions and quality and packaging specifications that will be included in a future definitive agreement.

Ultra-PMG™ represents approximately one-half of the expected production of purified graphite from the Kellyton Graphite Processing Plant. The other half of the expected production will be coated spherical purified graphite, or CSPG, which will be used in lithium-ion batteries including for electric vehicles. Ultra-PMG™ can be used in a variety of industrial applications. While customer interactions are ongoing related to our CSPG product and have gained momentum following the passage of the Inflation Reduction Act, executing agreements for Ultra-PMG™ is another positive step forward for Westwater. The amount of product covered by this LOI represents more than 25 percent of the expected annual production of Ultra-PMG™ at the Kellyton Graphite Processing Plant.
