• NFPA Conference provides a platform to accelerate firefighter adoption as lithium-ion battery fire incidents continue to rise across North

TORONTO, June 22, 2026 /PRNewswire/ - Full Circle Lithium Corp. ("FCL" or the "Company") (TSXV: FCLI) (OTCQB: FCLIF) (FSE: K0Q), a leading U.S.-based manufacturer of lithium-ion battery fire extinguishing products, is pleased to announce its participation in the upcoming National Fire Protection Association (NFPA) Conference today in Las Vegas, where the Company will engage with fire service leaders, safety professionals, regulators, and industry stakeholders from across North America.

The NFPA Conference arrives at a pivotal moment for Full Circle Lithium. Over the past four months, the Company has achieved significant commercial milestones that underscore the growing demand for specialized lithium-ion battery fire protection solutions.

Among the Company's recent achievements:

• Expanded production to full manufacturing capacity ahead of its North American retail rollout of FCL-X™ lithium-ion battery fire extinguishers.
• Successfully launched FCL-X™ into major U.S. retail channels, increasing accessibility for consumers, tradespeople, and commercial users.
• Announced the development of FCL-X™GEL, a second-generation product designed specifically for Battery Energy Storage Systems (BESS), one of the fastest-growing segments of the global energy market.
• Completed high-profile live burn demonstrations involving one of the world's largest logistics companies, seven major airlines, and representatives from the Federal Aviation Administration (FAA).
• Secured its first U.S. commercial deployment with a major waste management operator, addressing the rapidly growing challenge of lithium-ion battery fires in recycling and waste handling environments.

"Over the past several months, we've seen exceptional validation of both the problem and our solution," said Carlos Vicens, Chief Executive Officer of FCL "The demand for effective lithium-ion battery fire mitigation continues to accelerate across consumer, industrial, transportation, aviation, waste management, and energy storage markets. The NFPA Conference provides an ideal platform to connect with the fire service professionals who are on the front lines of this growing challenge."

The Company views the NFPA Conference as a critical event for the continued expansion of its firefighter and first-responder business line. Fire departments across North America are increasingly encountering lithium-ion battery incidents involving electric vehicles, e-bikes, e-scooters, energy storage systems, consumer electronics, and waste facilities. These fires present unique hazards due to thermal runaway, the potential for rapid reignition, toxic gas release, and prolonged burning.

As awareness of these risks grows, Full Circle Lithium believes firefighters are seeking practical, field-tested tools specifically designed to address lithium-ion battery incidents. The Company's participation at NFPA will focus on demonstrating the capabilities of the FCL-X™ platform and strengthening relationships with fire departments, training organizations, fire protection engineers, and emergency response agencies.

"Firefighters are increasingly being asked to respond to incidents that conventional suppression methods were never designed to handle," added Vicens. "NFPA plays an essential role in advancing fire safety standards, education, and best practices. We are proud to participate in this important gathering and support the fire service's efforts to address one of the fastest-growing fire risks of our time."

As electrification continues to expand globally, Full Circle Lithium remains committed to developing innovative solutions to protect people, property, critical infrastructure, and first
