GMG'S GRAPHENE ENGINE OIL ADDITIVE G LUBRICANT: PATENT GRANTED IN USA; ALLOWED IN CHINA

The patent for Graphene Manufacturing Group Ltd.'s graphene engine oil additive, G lubricant, has been granted for 20 years in the United States 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.

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 fuel 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 one-to-100 dosage, has been verified by the University of Queensland to increase fuel efficiency by up to 8.4 per cent in a diesel engine as announced in February, 2025.

The amount of graphene in the final engine oil once G lubricant is mixed in is only approximately one to 10,000. As a result, G lubricant can be used safely in any internal combustion engine. Over the past four years, Graphene Manufacturing has conducted environmentally controlled testing of G lubricant in internal combustion engines monitored and verified by the University of Queensland. Graphene Manufacturing's test results have been corroborated by similar savings realized by customers over a number of years of field testing.

$1.4-trillion (U.S.) global diesel industry

Whilst G lubricant can be used to reduce fuel consumption in both diesel and gasoline/petrol engines, Graphene Manufacturing intends to focus on the diesel market initially, which is largely business to business focused and, therefore, more targeted as far as fuel cost savings and performance. Graphene Manufacturing calculates, prior to the recent increase in diesel prices, that global diesel fuel sales totalled $1.4-trillion (U.S.) per annum, including taxes and duties on approximately 28 million barrels of diesel per day as detailed by the U.S. energy information administration.

Estimated $1.2-billion (U.S.) per annum global diesel market for G lubricant

Assuming an average fuel savings of 8.4 per cent, Graphene Manufacturing believes that a conservative estimate of the potential market for G lubricant is 10 per cent of the fuel savings realized by users annually. Assuming G lubricant pricing is equal to 10 per cent of the savings realized, Graphene Manufacturing estimates that the potential global revenue for G lubricant is $1.2-billion (U.S.) sales per annum based on 2025 actual sales.

Craig Nicol, chief executive officer and 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 Graphene Manufacturing Group Ltd.

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

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

In the energy storage segment, Graphene Manufacturing and the University of Queensland are working collaboratively with financial support from the Australian Government to progress research and development and commercialization of graphene aluminum-ion batteries. Graphene Manufacturing has also developed a graphene additive slurry that is aimed at improving the performance of lithium-ion batteries.

Graphene Manufacturing's four 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 and project execution capability.

We seek Safe Harbor.
