Westwater Resources, Inc. (NYSE American: WWR), an energy technology and battery-grade natural graphite development company (“Westwater” or the “Company”), announces that it has received final investment committee approval from the lead lender (a global financial institution), and the Company is working with Cantor Fitzgerald to finalize the overall syndication and closing of the debt financing for the Kellyton Plant. As a result, the estimated timing to close a debt financing transaction has been delayed.

“Given the ‘first of its kind’ nature of the Kellyton Plant, the due diligence process undertaken by the lead lender has been significant, and we are pleased to have approval from the lead lender,” said Steve Cates, Westwater’s SVP-Finance and CFO. “We are focused on getting the other interested lenders through their diligence and approval process and will provide further updates on timing once we have a better line of sight to closing.”

Westwater notes the closing of the debt transaction is also subject to customary agreement on final terms, completion of the syndication, final due diligence, and loan conditions.
