NEO Battery and NBM Korea Enters into Definitive Lease Agreement for Operational Battery Electrode Manufacturing Facility

• Entered into Definitive Lease Agreement with ENPLUS Co., Ltd. to Lease Operational Battery Components Manufacturing Facility Located in Gimje Free Trade Zone
• Leased Asset: Megawatt-Hour Lithium-Ion Battery Electrode Production Equipment and Facilities
• Three-Year Lease Term with Right of First Refusal to Renew Term on Same Conditions & Cash Security Deposit and Monthly Payment for Consideration
• To Initially Supply Existing Major Automotive OEMs and Downstream Manufacturers & Will Adapt to Produce Custom Silicon-Enhanced Electrodes for New Client Pipeline

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 electronics, is pleased to announce that the Company and its South Korean subsidiary, NBM Korea Co., Ltd., ("NBMK") have entered into a definitive lease agreement ("Definitive Agreement") with ENPLUS Co., Ltd., an arm's length party, ("Lessor") on November 10, 2025, to lease an operational battery electrode manufacturing facility.

This facility represents a major step toward NEO's transition from battery technology development to production, providing immediate access to commercial-scale manufacturing capability for advanced electrodes at the megawatt-hour (MWh) level. By extending operational shifts and implementing automation, NEO anticipates doubling capacity in the coming months, positioning the Company for accelerated commercialization and strategic scaling of its silicon-enhanced battery products.

Under the Definitive Agreement, NEO and NBMK have secured the full use of the facility's production equipment, office, warehouse, and auxiliary infrastructure for an initial three-year term, with a right of first refusal to renew under the same terms and conditions. The lease will be settled in cash through a lump-sum security deposit and monthly lease payments. Pursuant to the terms of the Definitive Agreement, the specific payment amounts will remain confidential to protect commercially sensitive information. There are no shares, warrants, or securities of the Company issued as consideration.

Initially, the facility will focus on supplying battery electrodes to existing major automotive original equipment manufacturers (OEM) and downstream clients, leveraging established relationships in the global battery supply chain. With production ramp-up, NEO will adapt the equipment to produce custom silicon-enhanced batteries tailored for its growing pipeline of new clients in the drone, robotics, and electronics sectors.

Mr. Spencer Huh, President & CEO of NEO, commented, "Our entry into this operating electrode manufacturing facility marks an inflection point for the Company, meaningfully advancing our transition into a production-ready battery company. This lease arrangement has allowed us to avoid the capital intensity associated with new plant builds, remove multiple quarters of construction and commissioning risk, and immediately manufacture high-quality battery products using NEO's proprietary technology and know-how".
