• Direct unit-level defense partnership with the Republic of Korea Army's 12^th Infantry Division – an active frontline division protecting Korea's DMZ
• Technical implementation and advisory of high-performance battery solutions tailored to operational demand of frontline drone and robotics platforms, targeting system improvements at unit-level
• Field-validated performance data to be procured for product optimization and evidence for formal defense acquisition engagements

TORONTO , April 1, 2026 /CNW/ - NEO Battery Materials Ltd. ("NEO" or the "Company") (TSXV: NBM) (OTC: NBMFF), a low-cost, silicon-enhanced battery developer that enables longer-running, rapid-charging batteries for drones, robotics, and physical AI, is pleased to announce entering into a formal defense cooperation agreement (the "Agreement") with the Republic of Korea ("ROK") Army's 12^th Infantry Division – an active frontline division utilizing drone and robotics systems within Korea's border and Demilitarized Zone ("DMZ").

Under the Agreement, NEO and the 12^th Infantry Division will partner on (i) the exchange of technical intelligence on high-energy battery technologies for defense drone and robotics platforms, (ii) technical implementation and advisory of battery and energy-related solutions for the specific operational demands from frontline and DMZ environments, and (iii) initiatives to enhance drone and robotics system efficacy at the brigade, battalion, and regiment-level. This unit-level engagement will generate field-validated performance data under live conditions, directly supporting the Company's strategy for formal military procurement consideration within the ROK Army and Ministry of National Defense.

With a strength of over 10,000 personnel, the 12^th Infantry Division operates tank, air defense, reconnaissance, and engineering battalions, including the use of drone and robotics systems to protect, patrol, and bolster Korea's strategically sensitive border zones. Extended system endurance, robust cold-weather performance, and fast-charging capabilities are direct operational necessities, and NEO intends to custom-engineer drone and robotics battery products to address these requirements.

Major General Woo-je Cho, Commander of the 12^th Infantry Division, remarked that, "South Korea's defense technology modernization is dependent on the integration and performance of autonomous systems in demanding frontline and DMZ environments. Collaborating with NEO Battery will provide our division, brigades, regiments, and battalions access to high-performance, Korean-sourced battery innovations that align with the ROK Army's commitment to strengthening uncrewed defense capabilities."

General (Ret.) C.J. Ko, Director of NEO and former Acting Chief of Staff of the ROK Army,commented, "This defense partnership with an active frontline division is expected to reduce our go-to-market timelines from initial deployment to full military procurement. In unit-level field use, NEO's battery solutions will undergo live stress testing, and the Company will gain access to unique datasets to further optimize products iteratively. With institutional relationships through the Association of the ROK Army, this direct engagement is intended to produce a body of operational evidence that will inform the Company's procurement discussions with the ROK Army and defense organizations across U.S. and allied governments."

About the ROK Army's 12 ^th Infantry Division
The ROK Army's 12^th Infantry Division, commonly known as the Eulji Division, was established in 1952 along with the 15^th Infantry Division. Stationed along Korea's eastern frontline in Inje, Gangwon Province, the division has maintained a defense posture along the DMZ since the Korean War, serving as the ROK Army's primary deterrent force against potential incursions from the North. Today, the division deploys conventional ground forces, with the gradual implementation of autonomous systems and drone/robotics capabilities, as part of the ROK Army's national efforts to modernize defense and defense technology operations.
