Item 5.1 Full Description of Material Change

On July 1, 2026, the Company's subsidiary, Largo USA, received a US$60.1 million firm-fixed-price delivery order, extending through January 2030, under the Company's recently awarded Contract by the DLA for the supply of high-purity V₂O₅ in support of the U.S. National Defense Stockpile. This is Largo's first delivery order under DLA's multiple awardee IDIQ contract that currently has a stated overall maximum value of $125 million.

The Contract provides for firm-fixed-price delivery orders to be issued over a five-year ordering period, with flexible delivery schedules subject to the terms and conditions of the award. The price is fixed per pound of V₂O₅ at a premium above current benchmark V₂O₅ price indexes in 2026, escalating 10% each year thereafter. The V₂O₅ supplied must meet stringent purity and quality specifications established by DLA, supporting aerospace-grade titanium alloys, advanced defense manufacturing, and emerging energy storage technologies.

Following a lengthy review and vetting process, the award establishes the Company as an approved supplier within the U.S. defense industrial base and critical materials ecosystem and positions the Company as part of the supply chain for the U.S. Government and the Department of Defense. Largo USA will serve as the contracting entity for all U.S. Government contract requirements, encompassing customer engagement, logistics coordination, quality assurance, compliance, and delivery execution. However, as an IDIQ arrangement, the Contract does not guarantee a minimum quantity of delivery orders, the value of actual orders may be less than the contract ceiling and the U.S. Government may terminate or modify the Contract for convenience. There can be no assurance of future delivery orders from the DLA.
