Secured CAD 392K purchase order contract from North American Fortune 500 automotive OEM customerOne of largest foundry contracts awarded to date following months of manufacturing and qualitative validation through past and existing projectsReceived UN 38.3 certification for 11.5Ah drone battery product to enable international shipping to U.S., Ukraine, Canada & EuropeIncreased volume of customer pipeline in various downstream verticals along with proprietary chemistries including 100% silicon, lithium-metal, and sodium-ion batteries

TORONTO, Sept. 17, 2026 /CNW/ — NEO Battery Materials Ltd. (“NEO” or the “Company”) (TSXV: NBM) (OTC: NBMFF), a low-cost, silicon-enhanced battery manufacturer enabling high-performance capabilities for drones, robotics, and physical AI, is pleased to announce that it has secured a purchase order agreement valued at approximately $392,000 CAD ($280,000 USD) from its existing North American Fortune 500 automotive OEM customer (the “Customer”). The order represents one of the largest contracts awarded to date within NEO’s foundry manufacturing portfolio.

The purchase order follows several months of validation of NEO’s battery manufacturing quality, operational efficiency, and cost competitiveness through past and existing projects undertaken with the Customer. Under its foundry model for automotive applications, NEO produces full battery cells according to customer-defined specifications and resolves process bottlenecks in advanced development projects for next-generation electric vehicle models. From small-scale evaluation to this purchase order contract, the progress attests to the Company’s engineering and production capabilities, and NEO will continue to collaborate on larger-volume orders/projects with the Customer.

Within the drone and defense portfolio, NEO has received UN 38.3 certification for its 11.5Ah cell product following the Korea Certification under the KC 62133-2 standard. UN 38.3 is a mandatory safety certification to enable shipping lithium-ion batteries by air, sea, and land across most jurisdictions. With the certification in place, NEO has established schedules to actively ship the 11.5Ah product internationally for sampling and commercial validation with drone, defense, and aerospace customers in the United States, Ukraine, Canada, and Europe.

“NEO is steadily yet successfully proving out our foundry capability with tier-1 customers and expanding manufacturing capacity at the 2nd cell assembly facility to accommodate contract manufacturing demand in the subsequent years,” expressed Mr. S.J. Youn, Head of Manufacturing & Facility Operations of NEO. “Due to our flexible manufacturing model, we have increased the volume of our customer pipeline to service various downstream applications and chemistries that include 100% silicon, lithium-metal, and sodium-ion batteries. With our defense drone portfolio, we aim to receive more UN certifications for different battery models and aggressively manufacture products with the main objective of converting sample evaluation to larger-magnitude, long-term orders.”
