Westwater Resources Inc. (NYSE American: WWR), an energy technology and battery-grade natural graphite development company ("Westwater" or the "Company"), today announced its first quarter results for the period ended March 31, 2022 and provided an update on its Kellyton graphite processing plant currently under construction in east-central Alabama.

"During the first quarter, construction activities continued at the Kellyton site where we began civil and earth work, hired a general contractor, built out administrative offices, hosted a groundbreaking ceremony, continued to order equipment for the plant and submitted the application for our wastewater disposal permit," said Chad Potter, President and CEO.

Mr. Potter continued, "In March 2022 the White House invoked the Defense Production Act to encourage domestic production of critical material, including graphite, for batteries in electric vehicles and clean energy storage to reduce our nation's dependency on imported graphite, most of it from China. In May 2022 the Department of Energy (DOE) issued a Funding Opportunity Announcement of $3.1 billion to fund investments within the battery supply chain for electric vehicles and increase domestic battery manufacturing. We at Westwater are monitoring these developments closely to determine the benefit to Westwater and its shareholders."

"Given the current supply chain issues, Management has prioritized the ordering of all long-lead equipment for the plant. We have assembled a world class construction management team, and we are hyper-focused on managing the impact to our schedule and budget due to these global supply chain issues," Mr. Potter concluded.

In April 2022, the Company completed its graphite and vanadium drilling activities at its Coosa graphite deposit. The exploration program was conducted on approximately 4,000 acres of the 41,900 acres for which Westwater holds minerals rights; core samples are currently being evaluated and the Company anticipates preparation of a technical resource report by the end of this year.

On April 19, 2022, the Company held a ceremonial groundbreaking for the Kellyton graphite processing plant. Governor Kay Ivey of Alabama and other elected officials attended the Company's ceremonial groundbreaking. Alabama is home to Mercedes, Honda, Hyundai, Mazda, and Toyota, and is among the top four states in the nation in the automotive industry. Westwater's Kellyton graphite processing plant is well located to participate in the fast-growing electric vehicle sector.

Westwater's patent-pending process to be used at the Kellyton graphite processing plant is safer and more environmentally friendly than any other process used worldwide. The Company anticipates it will process graphite into Coated Spherical Purified Graphite ("CSPG"), a high-performance anode material for lithium-ion batteries. CSPG also improves electrical conductivity for battery use in smart phones, computers, and other electronic devices.

"We finished the first quarter with a cash balance of $116.0 million and a working capital balance of $108.6 million. Our significant working capital balance and zero debt provide us with the ability to continue to move the construction of the Kellyton graphite processing plant forward," said Jeff Vigil, Vice President - Finance and CFO. Mr. Vigil concluded, "We have incurred $17.8 million of costs since beginning construction of Phase I of the Kellyton graphite processing plant. With our cash balance and no debt, we believe we have the liquidity to continue advancing our investment in Phase I of the plant."

Financial Summary

• Net cash used in operations was $2.1 million lower for the three months ended March 31, 2022, compared to the same period in 2021. The decrease in cash used in operations was a result of reduced product development expenses and arbitration costs.

• Product development expenses for the three months ended March 31, 2022, decreased $1.6 million compared to the same 2021 period. Product development costs for the first quarter of 2022 were related to continued product development and optimization costs; the prior-year period was impacted by the expenses related to the Definitive Feasibility Study for Phase I of the Kellyton graphite processing facility and the Company's pilot program, both of which were completed in the second half of 2021.

• General and administrative expenses for the three months ended March 31, 2022, increased by $0.1 million from the prior-year period. The increase quarter over quarter is due primarily to higher payroll costs as the Company continues to build out its team and to invest in sales and marketing.

• Consolidated net loss for the three months ended March 31, 2022, was $2.8 million, or $0.08 per share, compared to a net loss of $5.4 million, or $0.19 per share, for the same period in 2021. The $2.6 million reduction in net loss was due primarily to decreased product development expenses and arbitration costs.

• Cash and working capital as of March 31, 2022, was $116.0 million consistent with our cash balance at December 31, 2021. Working capital at March 31, 2022 was $108.6 million, which represents a decrease of $1.7 million compared to December 31, 2021. The decrease in working capital was primarily the result of costs incurred during the quarter of $14.5 million related to the Kellyton graphite processing plant, and operating cash expenditures of $2.7 million; offset partially by 7.4 million shares of common stock sold for net proceeds of $15.6 million pursuant to our Controlled Equity Offering^SM Sales Agreement with Cantor Fitzgerald & Co.
