Investing in public graphene stocks

Solidion Technology, an advanced battery technology solutions provider, has announced that it has entered into a securities purchase agreement with a new institutional investor for the purchase and sale of 2,333,000 shares of common stock (or common stock equivalents) in a private placement priced above market under Nasdaq rules. The offering is expected to result in gross proceeds of $35 million, before deducting offering expenses. 

The Company intends to use the net proceeds from the offering to support the commercialization of its patented Extreme-Climate Battery technology, fulfill customer demand, expand inventory, advance the building and testing of prototypes, and for working capital and general corporate purposes.

Vorbeck Materials has secured a $6.6 million contract from the U.S. Defense Logistics Agency (DLA) to support the development and deployment of its PFAS-free, graphene-enabled firefighting foam technology. The agreement is expected to strengthen the company’s operations in North Dakota while advancing environmentally safer alternatives to conventional firefighting agents that contain harmful “forever chemicals.”

Vorbeck’s solution includes a flame-retardant formulation that can be mixed with seawater, offering significant advantages for naval applications such as shipboard fire suppression. The technology is also suited for extreme cold environments, where saltwater’s lower freezing point enhances operational reliability.

Global Graphene Group has reported another sale of Solidion Technology shares, continuing a series of insider transactions involving the graphene-linked battery materials company. The latest filing shows the company sold 175,000 shares on June 4, 2026.

Following the sale, Global Graphene Group still held 1,569,695 shares of Solidion Technology.

First Graphene (ASX: FGR) has announced an agreement to acquire the assets, intellectual property, product lines and manufacturing capabilities of US-based MITO Material Solutions for up to $850,000, in a move aimed at strengthening its presence in North America and expanding its graphene offering.

MITO is an advanced materials company with established graphene-based products and manufacturing operations in the United States, meaning the transaction enhances both First Graphene’s commercial footprint and its technical capabilities. The acquisition will extend First Graphene’s portfolio beyond its PureGRAPH powders and dispersions into functionalized graphene and graphene oxide products. MITO’s offerings include E-GO, LIGRA, OMEGA and DELTA, which are used across thermosets, thermoplastics, composites, coatings, resins and liquid systems. The deal also adds capabilities in functionalizing graphite, graphene and graphene oxide, along with access to manufacturing equipment, licenses and know-how.

Concretene, the Manchester‑based DeepTech company developing graphene‑enhanced, low‑carbon concrete, has been named a winner in Ofwat’s sixth Water Breakthrough Challenge. The winning project, “Splitting Biogas, Multiplying Value,” is led by UK water utility United Utilities and aims to show how wastewater biogas can be converted into clean hydrogen and high‑value graphene, then used across construction, energy storage and transport applications.

Within this project, Concretene will use sustainably produced, UK‑sourced graphene derived from wastewater biogas in its concrete admixture technology, targeting significant reductions in cement content and embodied carbon while maintaining or improving performance. Concretene has been awarded £1 million out of a total £9.5 million funding package, which will support further product development, testing and early deployment of graphene‑enhanced concrete in real‑world infrastructure projects.

Skeleton Technologies has announced the first close of a larger funding round at €33 million. This brings its total venture capital funding to €392 million in preparation for its planned initial public offering (IPO) in the United States in 2027.

The new round expands Skeleton’s investor base with the addition of Axon Partners Group, SmartCap, and Taiwania Capital. More investors will be announced as part of a larger round ahead of the IPO.

Graphenory, a Japanese startup that develops optical devices using graphene, has announced that it has completed a seed round of funding totaling approximately ¥240 million (over US$1.5 million). Investors include SBI Investment, Keio Innovation Initiative, Mobile Internet Capital, Mizuho Capital, Fidea Capital, and Deepcore. Additionally, the company announced that it has completed the Keio University Startup Incubation Program (KSIP).

Graphenory is developing optical devices such as infrared light sources, analytical sensing, and optoelectronic fusion devices utilizing graphene materials, based on the research of Professor Hideyuki Maki from the Faculty of Science and Technology at Keio University. According to the company, its business areas span a wide range, including the semiconductor industry, information and communication, data centers, AI-related fields, quantum technology, and bio-medical sectors.

First Graphene (FGR) has announced it has entered a binding Asset Purchase Agreement to acquire all manufacturing, intellectual property and development assets of Ionic Industries and its subsidiary Imagine Intelligent Materials. FGR views this acquisition as a strategic and cost-efficient opportunity to integrate advanced graphene coatings technologies developed over more than a decade of research and commercialization activity.

Following a comprehensive due diligence process, First Graphene identified strong technical and commercial alignment with the Companies' graphene formulation platforms, which have already demonstrated successful application across multiple real-world use cases. Under the Agreement, First Graphene will acquire production infrastructure, intellectual property, and established sales and distribution channels for a total consideration of AU$250,000 (around US$180,000) in cash and shares.

Argo Graphene Solutions has announced a non-brokered private placement offering, for aggregate gross proceeds of CA$500,000 (over US$360,000). The offering will have an over-allotment option for up to additional gross proceeds of up to $75,000 (almost US$56,000).

The Company plans to use the proceeds of this offering for general working capital purposes and to continue its research and development of its graphene products.

Adisyn has reportedly secured firm commitments to raise AU$14 million (over US$10 million) through an institutional placement, backed by major investors following two key technology milestones in its graphene semiconductor and defense programs.

The raise was cornerstoned by one of Australia’s largest institutional investors, Regal Funds Management and Meitav, Israel’s largest investment house and led by Sandton Capital Advisory. Regal manages more than $20 billion, while Meitav manages about $190 billion in assets, with both investors bringing experience across technology and defense sectors.
