Graphyte Enters into Carbon Removal Prepurchase Agreement with Frontier

Graphyte satisfies Frontier technical diligence as condition of prepurchase

Pine Bluff, AR — November 20, 2025 — Graphyte today announced that Frontier, an advance market commitment (AMC) to purchase an initial $1B in permanent carbon removal launched by Stripe, Alphabet, Shopify, and McKinsey Sustainability to accelerate permanent carbon removal, has approved its technical diligence review, and is moving forward with a $250,000 prepurchase of durable carbon removal from Graphyte’s Arkansas project.

“This milestone speaks to the technical rigor of our Carbon Casting process,” said Graphyte CEO Barclay Rogers. Frontier’s prepurchase confirms that Graphyte can provide high-quality, verifiable carbon removal tons in the near-term.”

Kodama received a research and development (“R&D”) grant from Frontier in 2022, which was revised to reflect that Graphyte had acquired the carbon removal aspects of Kodama’s business. Having concluded its technical diligence of the updated R&D milestones, Frontier is prepurchasing 450 durable carbon removal tons generated through Graphyte’s Carbon Casting technology, a type of Biomass Carbon Removal and Storage (BiCRS).

To support transparency and industry learning, Graphyte will publish a Measurement, Reporting, and Verification (MRV) white paper outlining the underlying operational data, methodologies, and performance results used in the diligence process.
