Westwater Resources, Inc. (WWR) received written notice from SK On Co., Ltd. on March 31, 2026, terminating the Products Procurement Agreement, effective immediately. The agreement, originally executed on February 5, 2024, involved SK On purchasing CSPG natural graphite anode products from Westwater. The terminated agreement represented a portion of the planned Phase I production capacity at Westwater's Kellyton Graphite Plant. SK On cited the challenging and evolving environment customers are navigating as the reason for termination. SK On has indicated a willingness to consider future agreements, subject to updated terms and conditions. Westwater continues to progress construction and operational readiness at its Kellyton Graphite Plant. The company expects initial production of battery-grade graphite within approximately 12 months of securing the remaining project financing.
