Investing in public graphene stocks
Graphene is a one-atom-thick sheet of carbon atoms arranged in a honeycomb (hexagons or chicken-wire) crystal lattice. Graphene is the world's strongest and most conductive material, and no wonder that researchers and professionals looked into graphene's potential across many applications, including sensors, batteries, conductors, displays, electronics, energy generation, medicine and more.
The commercialization of graphene is just in its infancy, but already dozens of new companies have been established to develop graphene based materials, applications, graphene production processes and other related activities.
There are many companies directly involved with graphene. Most of these companies are either private early stage companies or large companies in which graphene is just one business segment, but some pure-play graphene companies are public. Below we will list some potential graphene stocks for investors that wish to take part in the graphene revolution. For a more in-depth analysis of the possibility of investing in graphene, and a complete public companies listing, see our Graphene Investment Guide.
Pure-play graphene companies
In the past few years several graphene producers and graphene application developers started trading in stock exchanges around the world - mostly in Australia, Canada and the UK. Here we'll list some of those companies:
Versarien (AIM:VRS) is an advanced materials group leveraging proprietary technology to create innovative engineering solutions for its clients in a diverse range of industries - focusing on graphene materials.
Haydale (AIM:HAYD) is a UK-based supplier of functionalized graphene and related technologies. Haydale is mostly involved with graphene composite solutions and graphene-based inks. In 2016 Haydale acquired ACMC, a US-based silicon carbide whisker manufacturer.
G6 Materials (TSX: GGG), formerly known as Graphene 3D Lab, focuses on development of high-performance graphene-enhanced materials.
Other graphene investment options
Several large and public companies (such as Samsung, Intel, Nokia, IBM and Sony) are involved in graphene research. These companies may be on the forefront of graphene research - especially in high-end fields such as electronics and photonics - but graphene, even if successful, will probably represent a small portion of their business.
Another option is to invest in graphene production equipment. Aixtron SE, for example, is a provider of deposition equipment to the semiconductor industry who offers CVD graphene production systems. Aixtron trades in the NASDAQ (ticker:AIXG). US-based CVD Equipment Corporation also offers graphene R&D and production equipment. CVD Equipment trades in the NASDAQ (ticker: CVV).

The PERTE Chip initiative - “Strategic Project for Economic Recovery and Transformation of Microelectronics and Semiconductors” - aims to strengthen the design and production capabilities of the microelectronics and semiconductor industry in Spain from a comprehensive perspective, while promoting strategic technological autonomy for both Spain and the European Union.
New project awarded £6 million to develop 2D materials to reduce the electricity demand from AI data centers and high-performance computing
Scientists from three UK universities have been granted £6 million to develop single-atomic layer semiconductors under a program called NEED2D (“Enabling Net Zero and the AI Revolution with Ultra-Low Energy 2D Materials and Devices”).
The materials to be developed include graphene and related compounds. The goal is achieving energy efficient, atomically-thin semiconductors to dramatically reduce the electricity demand from AI data centers and high-performance computing.
Graphene-Info releases a new edition of its Graphene Investment Guide
Today we published a new edition of our Graphene Investment Guide, with all the latest information and financial updates from public graphene companies. This is still a challenging time for many graphene companies - and also for graphene investors, but we are seeing signs of increased activity and improved conditions in the graphene industry, which will hopefully contribute to public graphene companies. This new edition includes four new public graphene companies, another sign that the industry is recovering.
It is a time of consolidation in the industry - and investors should be careful when looking at early stage graphene companies. Most graphene companies struggle to generate meaningful revenues, and we expect consolidation and liquidation to continue in the next few years.
The Graphene Investment Guide includes:
- An introduction to graphene
- An overview of graphene's most exciting applications
- An analysis of graphene's potential
- Market forecasts from leading analysts
- Detailed descriptions and financials of all public graphene companies
- Over 80 financial reports and company presentations (premium edition only)
- Graphene-Info's own investment thesis and action plan
Any technology-driven investor that wishes to stay current on the most promising new nanotechnology should look into this report. The report includes extensive data and information needed to launch a successful strategic graphene investment portfolio.
