Brisbane, Queensland, Australia--(Newsfile Corp. - July 21, 2026) - Graphene Manufacturing Group Ltd (TSXV: GMG) (OTCQX: GMGMF) ("GMG" or the "Company") is pleased to announce a global exclusive Memorandum of Understanding (MOU) with Alstom (EPA: ALO) for testing and developing graphene products for the rail industry — specifically for Heating, Ventilation, Air Conditioning (HVAC) systems.

Craig Nicol, CEO & Managing Director of the Company, commented "We are thrilled to be partnering with Alstom, one of the world's most recognised names in rail and transportation. This global exclusive MOU gives GMG the opportunity to bring our graphene technology into one of the largest and most technically demanding sectors in the world. Rail systems demand the highest standards of performance, durability and efficiency — and we believe graphene is uniquely positioned to deliver meaningful improvements across a range of applications. We look forward to working closely with the Alstom team to develop and commercialise graphene products that will help shape the future of rail."

Jack Perkowski, Non-Executive Chairman and Director of the Company, commented: "Securing a global exclusive MOU with Alstom is a landmark moment for GMG. Alstom operates at the very highest level of global transportation infrastructure — serving cities, governments and rail operators across the world with a presence that spans every major market. The fact that a company of Alstom's scale and technical sophistication has chosen to partner exclusively with GMG to evaluate develop and commercialize graphene-based products for the rail industry is a powerful validation of our technology and our team's capabilities. This arrangement has the potential to open a new revenue stream for GMG and reinforces our strategy of targeting large, established industries where graphene's unique properties can deliver measurable, real-world impact."

Alstom is a pure rail leader, committed to making rail the backbone of sustainable transportation. The company designs and delivers a complete range of future-ready solutions — from high-speed and regional trains to metros, monorails, trams, turnkey systems, end-to-end services, infrastructure, signalling and digital rail solutions. With 87,800 people in 61 countries, Alstom brings together global expertise and multi-local presence to make every journey smarter, cleaner and more enjoyable. Together with our partners and customers, we realise the power of rail. Listed in France, Alstom generated revenues of €19.2 billion for the fiscal year ending 31 March 2026.

About GMG:

GMG is an Australian based clean-technology company which develops, makes and sells energy saving and energy storage solutions, enabled by graphene manufactured via in house production process. GMG uses its own proprietary production process to decompose natural gas (i.e. methane) into its natural elements, carbon (as graphene), hydrogen and some residual hydrocarbon gases. This process produces high quality, low cost, scalable, 'tuneable' and low/no contaminant graphene suitable for use in clean-technology and other applications.

The Company's present focus is to de-risk and develop commercial scale-up capabilities, and secure market applications. In the energy savings segment, GMG has initially focused on graphene enhanced heating, ventilation and air conditioning ("HVAC-R") coating (or energy-saving coating) which is now being marketed into other applications including electronic heat sinks, industrial process plants and data centres. Another product GMG has developed is the graphene lubricant additive focused on saving liquid fuels initially for diesel engines.

In the energy storage segment, GMG and the University of Queensland are working collaboratively with financial support from the Australian Government to progress R&D and commercialization of graphene aluminium-ion batteries ("G+AI Batteries"). GMG has also developed a graphene additive slurry that is aimed at improving the performance of lithium-ion batteries.

GMG's 4 critical business objectives are:

1. Produce Graphene and improve/scale cell production processes
2. Build Revenue from Energy Savings Products
3. Develop Next-Generation Battery
4. Develop Supply Chain, Partners & Project Execution Capability
