Largo Announces Strategic Focus on Higher-Margin Products; Provides Update on Copper-Platinum Group Metal Margins and Potential Expansion; and Further Advances Debt Restructuring

Key Highlights: * Higher-margin production strategy: Largo is optimizing its production mix toward high-purity vanadium and copper-platinum group metals ("PGMs") by-products, which currently generate materially higher margins than the Company's standard-grade vanadium products and ferrovanadium ("FeV"). * Largo's recent sales of copper-PGM concentrates are generating approximately US$4.7 million in revenue and an operating profit margin above 90%, making it the Company's highest-margin product. The Company is evaluating a potential expansion to double copper-PGM concentrate production in 2027. * The Company has produced and shipped its first high-purity vanadium pentoxide material for the U.S. Defense Logistics Agency ("DLA") and is currently completing production of its second shipment. * Largo executed a definitive debt-restructuring agreement with Banco do Brasil, its largest creditor, with key provisions consistent with the binding term sheet announced in the Company's August 20, 2026 press release. Together with the previously announced definitive agreement with Caixa Econômica Federal, the Company has now executed definitive restructuring agreements representing approximately 48% of its US$82 million in commercial bank senior debt.
