Graphene.
Hide the graphene.

The most telling graphene headline of the year was a name change. In January, Haydale Graphene Industries became Haydale plc, and it wasn't the only graphene company having a rough year. Versarien went into administration that same month. Directa Plus followed in April. In September, CVD Equipment, which sold the machines that grow the stuff, stopped taking orders for them.

The graphene companies still standing have worked out what the dead ones didn't: nobody buys graphene. They buy a lighter truck part, a stronger bag of cement, an air conditioner that uses less power.

That isn't because the material disappoints. Graphene is a single layer of carbon atoms arranged in a honeycomb, absurdly strong for its weight and very good at conducting heat and electricity, and the work that first isolated it won a Nobel Prize in 2010. What gets sold as graphene is mostly powder made of thin stacks of those layers, mixed in small doses into plastics, concrete, coatings, and battery electrodes. The trouble is that there's still no standard grade. One supplier's graphene can behave differently from the next, so every customer tests before buying, and testing takes years.

So the material works, and the volume keeps not showing up. First Graphene's powder has gone into more than 20,000 tonnes of UK cement, and the company booked about A$540,000 of revenue for its trouble. NanoXplore, the world's largest producer, just watched two Volvo programs slip a year. Graphene stocks have priced that in.

The question for every graphene stock in 2027 is how close it sits to the thing the customer actually buys. This list of graphene stocks runs from closest to furthest: the ones that make the part, the ones selling a branded product, the powder makers still selling the material itself, and the private companies with the most money behind them.

These companies stopped waiting for customers to figure out graphene and started making the finished part themselves. That puts them closest to the money of any graphene stocks.

NanoXplore TSX: GRA

NanoXplore runs the largest graphene powder plant in the world, about 4,000 tonnes a year in Montreal. That isn't where most of its money comes from.

Most of its C$117 million in the fiscal year to June came from molding composite panels and parts for heavy trucks, for customers like Volvo and Paccar. It is putting its own graphene into more of those parts, including at a newer plant in North Carolina. The material doesn't have to win a purchasing fight on its own when it rides inside a part the truck maker was already going to buy. Management is guiding to C$130–140 million next year, with positive free cash flow.

Black Swan Graphene TSXV: SWAN

Black Swan Graphene makes graphene powder at a plant in Consett, England, and more than tripled its capacity to over 140 tonnes a year in March. A month later it bought Falpaco, a rubber and plastics compounder with about C$7.4 million in annual sales.

For a producer this small, that's the right move. Instead of waiting two years for someone else's compounder to qualify its powder, Black Swan now owns one. Most of what Falpaco sells today has no graphene in it, and Black Swan's job now is to change that.

Here graphene is one ingredient in a product with its own name, sold to buyers who may never hear the word.

Graphene Manufacturing Group TSXV: GMG

Graphene Manufacturing Group makes graphene in Brisbane by cracking natural gas with plasma. Most investors know it for a fast-charging aluminium-ion battery that's still in development. That's not why it's here.

The reason is THERMAL-XR, a graphene coating sprayed onto air-conditioning coils to restore heat transfer and cut power use. The EPA cleared it for sale in the U.S. in March, and HVAC chemicals supplier Nu-Calgon sells it to contractors under its own CoolWorx brand. A contractor doesn't need to understand graphene to sell a customer a lower power bill.

GMG raised US$10 million in late September. If the coatings business starts paying its own way, the battery work stops depending on the next raise.

Haydale AIM: HAYD

Haydale is the turnaround on this list, and the name change is the plan. In January it bought SaveMoneyCutCarbon, an energy-efficiency retailer and installer, in an all-share deal, and raised about £5.75 million at half a penny a share alongside it.

Graphene now rides inside that business. Haydale's JustHeat underfloor heating panels run on its graphene ink, and the new installer network gives them somewhere to sell. Revenue for the six months to March jumped more than fivefold to £2.25 million, though little of that is graphene yet.

This is a heavily diluted microcap. Whether the heating panel turns into a real product line is the whole bet.

These companies still sell graphene as graphene. That's the hardest job on the list, and each has its own answer for why it'll work.

First Graphene ASX: FGR

First Graphene has the best proof of the additive model and the worst economics, in one company. Its PureGRAPH powder has gone into more than 20,000 tonnes of cement in the UK through Breedon, where a small dose lets producers make strong concrete with less clinker, the most carbon-heavy ingredient.

The problem is the dose. A sliver of graphene per tonne of cement doesn't add up to much revenue, and the company booked a A$5.4 million loss for the year to June with under A$3 million left in the bank. It's a sub-A$50 million microcap. If one major cement producer standardizes on PureGRAPH, the math changes fast. Without that, A$3 million doesn't last long.

HydroGraph CSE: HG

HydroGraph is betting the missing ingredient is consistency. Customers won't design in a material that behaves differently from batch to batch, and that has held graphene back for a decade.

HydroGraph says its reactor makes high-purity graphene the same way every time, and it's the only producer in the Americas certified under the Advanced Carbons Council's verified-producer program. Investors bought the pitch to the tune of C$70 million in August, at C$6.80 a unit, and the company is planning a plant in Bellville, Texas. The stock now trades around C$3.80.

The biggest graphene bets aren't listed, and the best-funded ones are graphene companies only on the inside.

Lyten (Private)

Lyten has raised more than $625 million to build lithium-sulfur batteries around its 3D Graphene material, with no nickel, cobalt or manganese in the cell. In February it closed its purchase of Northvolt's Swedish gigafactory and labs, 16 GWh of capacity, with plans to restart them making conventional lithium-ion cells.

That's the graphene story in miniature. The most ambitious company in the space bought a factory for a product people already buy, and plans to slot the material in later.

Skeleton Technologies (Private)

Skeleton Technologies makes supercapacitors from what it calls curved graphene, and it found a buyer with deep pockets in AI data centers. Its systems smooth out the violent power swings that GPU clusters throw at the grid.

It has raised €392 million and says it's aiming for a U.S. listing in 2027. That would be the first chance in years to buy a graphene company with a growth market attached.

Paragraf (Private)

Paragraf is the only company here still chasing the original dream of graphene in electronics. It grows graphene directly onto wafers, skipping the transfer step that usually contaminates it, and sells graphene magnetic sensors today. A $55 million Series C in August 2025 keeps it going. If graphene ever gets into chips at scale, this is the most likely route.

Levidian (Private)

Levidian is on this list as a threat. Its LOOP reactor cracks methane into hydrogen and graphene at the same time, so the graphene is a byproduct of making hydrogen rather than the thing it has to sell at a profit. It's running projects with United Utilities in the UK and Gas Malaysia.

If that scales, graphene gets cheap for everyone. That's good news for the product companies above, and bad news for anyone whose moat is a big powder plant.

Graphene's best outcome is getting boring.

The additive it really competes with is carbon black, the sooty powder that goes into every tire and most battery electrodes. Nobody brands carbon black. It's sold by grade number off a spec sheet, by chemical companies whose customer relationships go back decades. That's what a grown-up additive looks like.

Graphene isn't there because there's no agreed grade yet, so every buyer runs its own long qualification. Once a few grades become standard, that wall comes down. Qualifying a new supplier gets faster, prices fall, and the moat stops being the plant and becomes the customer relationship. NanoXplore's newest high-purity powder is already pitched at jobs where carbon black dominates today.

That world favors whoever already owns the spec sheet and the purchase order: the part makers on this list, and eventually the big carbon-additive suppliers who've never called themselves graphene companies. Among today's graphene stocks, the powder makers that survive it will be the ones whose product becomes the grade everyone else gets measured against.
