GMG LAUNCHES NEW GRAPHENE WATER COOLANT ADDITIVE FOR DATA CENTRES: G FLUID

Graphene Manufacturing Group Ltd. has launched patent-pending G Fluid for use as a graphene water-based additive for data centre and industrial cooling circuits to increase heat transfer and reduce microbial and bacterial growth. The cooling water treatment chemicals market is valued at $15-billion (U.S.) per annum in 2026 and is expected to be valued at $27.2-billion (U.S.) per annum in 2035 (with a 6.1-per-cent CAGR (compound annual growth rate)).

G Fluid is expected to provide a higher heat transfer rate for data centre and industrial cooling systems -- with preliminary internal testing showing an increased heat transfer rate of approximately 20 per cent when G Fluid is dosed into demineralized water at 1 per cent -- providing 0.01 per cent of graphene by weight in final solution.

Please see launch video of how G Fluid and Thermal-XR can support energy reductions for data centres.

G Fluid provides up to 87-per-cent anti-microbial testing outcomes as tested by an independent third party laboratory under testing standard EN 1276. Figure 3.0 shows the various test results from the third party laboratory for anti-microbial performance due to G Fluid dosed at 1 per cent -- providing 0.01 per cent graphene by weight in the final solution.

Graphene's managing director and chief executive officer, Craig Nicol, commented: "G Fluid lets a data centre, industrial plant or building operator improve the heat transfer of the water or coolant already running through their cooling loop, at a simple 1-per-cent dose rate. Independent laboratory testing to the EN 1276 standard also shows a meaningful reduction in microbial growth in that same water, which matters for anyone managing corrosion, fouling and maintenance costs in a chiller system. We're launching first into data centres, where cooling demand is growing fastest, but the same dosage works in industrial process chillers and building chiller systems, giving us a large market to grow into."

Graphene's chairman and director, Jack Perkowski, commented: "G Fluid is our fourth energy-saving product alongside Thermal-XR and G Lubricant, and it gives GMG a foothold in a cooling water treatment market worth more than $15-billion (U.S.) a year globally, growing quickly as AI-driven data centre construction accelerates. It's a strong example of how our graphene production capability keeps opening up new, commercially relevant applications across very different industries."

U.S. EPA application update

Graphene is also pleased to announce the company has submitted an amendment application to the United States Environmental Protection Agency (EPA) seeking approval to manufacture, in addition to sell, graphene and GMG's Thermal-XR, G Lubricant and G Fluid products in the United States. This was based on the advice from the EPA to replace the significant new use notice (SNUN) the company submitted in June, 2026. Graphene expects an EPA approval for this amendment by the end of September, 2027, and the existing consent order conditions are not impacted for Thermal-XR sales into the United States.

About Graphene Manufacturing Group Ltd.

Graphene Manufacturing Group 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. 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, "tuneable" 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 (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 Graphene Manufacturing has developed is the graphene lubricant additive focused on saving liquid fuels initially for diesel engines. Graphene Manufacturing is also developing a graphene coolant additive focused on energy saving for data centres and industrial cooling applications.

In the energy storage segment, Graphene Manufacturing and the University of Queensland are working collaboratively with financial support from the Australian government to progress R&D (research and development) and commercialization of Graphene Manufacturing graphene batteries. Graphene Manufacturing has also developed a graphene additive slurry that is aimed to improve 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.
