Graphene Manufacturing Group (GMG) is a Canadian company that makes graphene — a material formed from a single layer of carbon atoms that is extremely thin but very strong and conductive. The company produces graphene using natural gas and sells it to industrial customers for use in products like lubricants, coatings, and batteries. GMG is also developing its own graphene aluminum-ion batteries, which it hopes can compete with lithium-ion batteries in energy storage markets.

GMG earns revenue by selling graphene-based products directly to manufacturers, and it is working toward commercializing its battery technology for applications like grid storage and electric vehicles. The company operates primarily in Australia and Canada and is still small, with a market cap around $200 million. Its deep operating losses — over 160% of revenue — reflect that it is an early-stage company spending heavily on research and development. The main risk is that it may struggle to scale production and reach profitability before needing to raise additional capital.

Strong grower

Graphene Manufacturing Group is growing revenue at 244% year-over-year. The Winston Score penalises unprofitable companies, but revenue at this pace tells a different story — this is a company still in "build mode."

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
