Introduction

Graphene Manufacturing Group Pty Ltd (OTC: GMGMF, TSXV: GMG) is a disruptive Australia-based clean-tech company that manufactures and distributes graphene globally. The company focuses on producing and selling energy-saving products and solutions and energy storage products. It achieves the objective through the in-house manufacture of graphene via a proprietary production process. The company operates through the energy-saving and energy-storage segments. The energy-saving segment focuses on Graphene-enhanced heating, ventilating, and air conditioning (HVAC) coatings, fluids, and lubricants. On the other hand, the energy storage segment deals with the commercialization of GMG graphene aluminium-ion batteries. GMG's services cut across numerous markets, including facility management, food supply management, transport and earth-moving, shopping centres and food outlets, retail, automotive operations and maintenance, and institutions. The company was founded in 2016 and had its headquarters in Richlands, Queensland, Australia. GMG’s common stock publicly-trade on TSXV under the GMG symbol, on Tradegate in Germany under “0GF”, and on OTC markets under the GMGMF ticker symbol.

The company began trading on the Pink Sheets in May of 2021 and was upgraded to the OTCQX market in February of 2024.

GMG Business Operations

GMG’S primary goal is to develop applications for energy-saving and energy-storage solutions. In 2017 and 2018, the company engineered and proved a unique proprietary production process that generates GMG Graphene from natural gas (methane), contrary to traditional production from mined Graphite. Its technology thus cracks methane to produce graphene and hydrogen. The process results in high quality, low input costs, scalable, ‘tuneable’, and low contaminant Graphene. The company uses graphene’s low input cost source to generate value-added products that clinch the massive energy efficiency and energy storage market demands. The ultimate product is employable in clean technology applications across various industries, leading to environmental improvements. GMG is exploring further opportunities for GMG Graphene, e.g., manufacturing next-generation batteries and jointly working with leading institutions in Australia to investigate ways to ameliorate the performance of lubricant oil and performance-enhanced HVAC-R coating systems.

Products

Super G

GMG introduced a liquid graphene slurry product in late 2024, for use in lithium-ion batteries. This product aims to optimize efficiency, power, and longevity, providing battery manufacturers with an innovative solution for next-generation energy storage. A study conducted by Oxford University indicates the slurry will will increase battery life and provide structural stability during calendaring.

Graphene Aluminum-Ion Battery

Laboratory tests and experiments have shown that the battery technology has higher energy and power densities than the popular Lithium-Ion Battery technology. The tests reveal that Graphene Aluminium-Ion Battery will have up to three times more life and charge up to 70 times faster. The University of Queensland Research and UniQuest are underway with the scale-up research project on the product.

The company announced on Dec. 12, 2022 that its board had approved the investment of an additional $AU 600,000 in capital expenditure to facilitate the development of Graphene Aluminium Ion (G+AI) Battery cell and propel semi-automatic pouch cell prototype production in its Battery Development Centre ("BDC") to be tested by customers. GMG says its batteries could be employed in many applications, including IoT sensors, personal mobility devices, energy storage, electric vehicles, personal electronics, etcetera. GMG continues to seek collaborative partnerships with a significant number of potential battery customers to drive the commercial development program further next year.

A significant milestone was reached in early 2024 as the company was able to produce a 1000mAh battery which was a stated goal of the company and a component of their joint development agreement with Rio Tinto. In March, 2025, GMG announced enlisting the Battery Innovation Center in Indiana, in order to advance electrochemistry optimization, battery performance and scaling.

Thermal XR

Thermal XR is an HVAC Energy Savings Coating System improves the efficiency of heat exchange surfaces. The process coats and cubs mangled heat exchange surfaces while repairing lost corroded thermal conductivity and boosting the heat transfer rate. The technology relies on the physics of GMG Graphene to improve efficiency and reduce power consumption. Graphene offers better thermal conductivity, 10-15times greater than copper and aluminium. It is also corrosion resistant, meaning it protects metal surfaces of systems from rusting.

THERMAL-XR® coating has surpassed 15,000 hours in salt sea spray corrosion testing (ASTM B117) at a U.S. third-party lab. The company believes this makes THERMAL-XR® one of the most durable corrosion protection coatings available. Testing is ongoing, with further updates expected.

G-Lubricant

G-Lubricant is a concentrate of GMG Graphene and lubricating oil (1%) made to save on energy and emissions and prevent wear. When added to engine oil, it forms a protective layer between metal interfaces, thereby reducing friction. Multi-year performance testing was completed in 2025, and showed a fuel savings of up to 8.4%.

Partnerships, Awards and Grants

Queensland Government

Graphene Manufacturing Group (GMG) received a AU$2 million grant from the Queensland Government to advance the creation of an automated battery pilot plant for their graphene aluminum ion battery. This funding is designed to enhance the local critical minerals and battery technology sectors, thereby fostering economic growth. The grant will cover 50% of the plant's capital costs, which will be situated in GMG’s current facility, pending the company's final investment decision.

Air Conditioning Refrigeration Building Services

THERMAL-XR received the Product Excellence HVAC Award at the Air Conditioning Refrigeration Building Services Exhibition (ARBS) in Sydney, Australia. This event is the premier gathering for the heating, ventilation, air conditioning, refrigeration (HVAC-R), and building services sectors in the country. The Product Excellence HVAC Award recognizes innovations in new technology or the innovative re-application of existing technology in the air conditioning, refrigeration, and building services industry.

Rio Tinto

Rio Tinto made a commitment to provide AU$6 million in funding towards the development of GMG's graphene aluminum battery in a pouch pack form. Under the terms of the agreement GMG will still own the intellectual property and Rio Tinto will secure the right to buy the batteries before other potential customers. Rio Tinto is one of the largest mining companies in the world.
