ZUG, Switzerland, Oct. 26, 2026 (GLOBE NEWSWIRE) — Lithium Argentina AG (“Lithium Argentina” or the “Company“) (TSX: LAR) (NYSE: LAR) today announced that it has repurchased $200 million aggregate principal amount of its convertible senior notes due January 2027 (the “2027 Notes“) in privately negotiated transactions with a limited number of qualified institutional buyers for approximately $198 million in cash, plus accrued interest. The repurchases were funded with cash on hand, including proceeds of the $180 million strategic investment from Ganfeng Lithium Group Co., Ltd. (“Ganfeng”) that closed on September 15, 2026. Following the repurchases, approximately $59 million aggregate principal amount of the 2027 Notes remains outstanding. Lithium Argentina intends to repay the remaining balance at or before its January 15, 2027 maturity from cash on hand, which exceeded $100 million following the repurchases, further reducing its overall debt.

“Repurchasing the majority of the 2027 Notes with cash is the next step in deleveraging and strengthening our balance sheet,” said Sam Pigott, Chief Executive Officer. “With no other corporate-level debt maturing until 2032 and Cauchari-Olaroz generating strong cash flow, we are well positioned to allocate capital in the way that best serves our shareholders.”
