Brisbane, Queensland, Australia--(Newsfile Corp. - April 20, 2026) - Graphene Manufacturing Group Ltd (TSXV: GMG) (OTCQX: GMGMF) ("GMG" or the "Company") is pleased to advise that GMG's patent for GMG's Graphene Engine Oil Additive, G® LUBRICANT, has now been granted for 20 years in the USA and allowed in China. This is in addition to the previously announced G® LUBRICANT patent accepted for the European region. There are various other countries around the world where this patent application is progressing as well, which are shown in Figure 1.

About G® LUBRICANT: G® LUBRICANT is what management believes to be a transformative graphene liquid concentrate additive designed to enhance the performance of diesel and gasoline (petrol) engines. This product has the potential to reshape the future of the global liquid fuels industry and offers an innovative solution that optimizes efficiency and power for stationary or mobile engines. G® LUBRICANT, a graphene liquid concentrate that can be added to any mineral or synthetic oil used in an internal combustion engine in a 1:100 dosage, has been verified by the University of Queensland to increase fuel efficiency by up to 8.4% in a diesel engine as announced in February 2025. [1]
The amount of graphene in the final engine oil once G® LUBRICANT is mixed in is only ~ 1:10,000. As a result, G® LUBRICANT can be used safely in any internal combustion engine. Over the past four years, GMG has conducted environmentally controlled testing of G® LUBRICANT in internal combustion engines monitored and verified by The University of Queensland. GMG's test results have been corroborated by similar savings realized by customers over a number of years of field testing.
US$ 1.4 Trillion Global Diesel Industry
Whilst G® LUBRICANT can be used to reduce fuel consumption in both diesel and gasoline/petrol engines GMG intends to focus on the diesel market initially, which is largely B2B focused, and therefore, more targeted as far as fuel cost savings and performance. GMG calculates, prior to the recent increase in diesel prices, that global diesel fuel sales totaled US$1.4 Trillion per annum[2] including taxes and duties on approximately 28 million barrels of diesel per day as detailed by the US Energy Information Administration2. Figure 3 shows the top 34 countries in the world with diesel fuel sales greater than US$10 Billion per annum.

Estimated US$ 1.2 Billion Per Annum Global Diesel Market For G® LUBRICANT
Assuming an average fuel savings of 8.4%, GMG believes that a conservative estimate of the potential market for G® LUBRICANT is 10% of the fuel savings realized by users annually. Assuming G® LUBRICANT pricing equal to 10% of the savings realized, GMG estimates that the potential global revenue for G® LUBRICANT is US$ 1.2 Billion sales per annum based on 2025 actual sales. Figure 3 shows GMG's estimates of potential annual sales of G® LUBRICANT by country.

Craig Nicol, CEO & Managing Director of the Company, commented "This is great progress to secure the valuable graphene lubricant patent for engine oil use in the major markets of Europe, China and the USA."
Jack Perkowski, Chairman and Non-Executive Director of the Company, commented: "Congratulations to the team on progressing further with building their competitive position in securing patents in the most valuable markets for G® LUBRICANT".
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:
- Produce Graphene and improve/scale cell production processes
- Build Revenue from Energy Savings Products
- Develop Next-Generation Battery
- Develop Supply Chain, Partners & Project Execution Capability
