Graphite One Pins Ohio Anode Debut on Purchased Synthetic Graphite as Air Permit Lands

Graphite One has locked in a clearer runway toward anode material production in Ohio — and it intends to get there using bought-in synthetic graphite rather than feedstock from its own Alaska deposit. The company's freshly detailed schedule targets first sales from the Conneaut facility in the fourth quarter of 2028, a timeline that hinges on planning, further permits, financing, construction and customer qualification.

The Ohio EPA's final air permit for the plant, announced on 2 November, marks the most tangible regulatory milestone so far. The first phase is sized at 10,000 tonnes per year and, according to the company, should pave the way toward a final investment decision. Investors welcomed the news: the stock climbed 4.0% on Friday.

A Two-Track Feedstock Strategy

That opening phase will process purchased synthetic graphite into anode material — a different supply route from the long-term chain built around the Graphite Creek project in Alaska. For shareholders, the Ohio build-out therefore stands as a project segment in its own right, one that can advance independently of the mining asset.

Capital spending for the initial stage is estimated at USD 80 million, a figure Graphite One says it will update once final engineering is complete. The company is aiming for an investment decision by April 2027. Beyond the remaining state and local approvals, customer qualification is a prerequisite, and Graphite One points to non-binding supply arrangements with Lucid Motors as part of that effort.

Financing Backstop Tops USD 2 Billion

Underpinning the plan is a non-binding letter of interest from the Export-Import Bank of the United States covering USD 1.4 billion for the Ohio expansion. A further USD 670 million in non-binding interest relates to Graphite Creek, bringing the potential financing envelope to USD 2.07 billion. What matters for valuation is not the headline figure but how firmly those indications of interest convert into committed funding.

Ohio's build-out is designed to scale in increments of 25,000 tonnes per year, with a long-term ceiling of up to 100,000 tonnes annually. Each step remains contingent on financing and on the successful delivery of the preceding phases.

Alaska Timeline Slips

The same announcement pushed back the Graphite Creek mine's production start to 2030. Media reports noted that Graphite One had still been targeting 2029 as recently as July 2026, and that the Ohio sales start is now roughly a year later than previously expected. The company did not give a reason for the revised dates, according to those reports.

Longer term, Graphite One envisions a US supply chain spanning mining and processing in Alaska, transport through the port of Nome, and graphite and anode material production in Ohio, with potential recycling facilities rounding out the concept.

Defense Work Adds a Second Demand Channel

Separately, Graphite One's wholly owned subsidiary Graphite One (Alaska) Inc. has been awarded a program order by the Defense Logistics Agency — reported about two weeks ago — to develop and evaluate advanced carbon materials sourced domestically. The program targets thermal-management applications in the defense sector where materials must withstand high temperatures, drawing on the Graphite Creek deposit as its material base. The subsidiary is working with partners from a national laboratory and industry advisers, with the Idaho National Laboratory named explicitly.

For investors, the next checkpoint is the planned investment decision on the first Ohio phase. It would firm up the path to the targeted 2028 sales if planning, permitting and financing move forward accordingly. The larger expansion remains tied to getting those foundations right first.
