Supported by significant progress in the financing of its industrial project in France, Carbios confirms its objective to build the Longlaville plant

Carbios confirms its objective to build the Longlaville plant.

1. Longlaville Plant Project

Carbios confirms its objective to build the Longlaville plant and indicates that it has continued to work on structuring the financing required to resume the project.

Discussions aimed at finalizing this financing structure are progressing constructively but are not yet completed.

In addition to the €42.5 million public funding that has been confirmed and contractually secured, the financing of Carbios 54 (the entity created to operate the project) would come from:

• Debt financing from partnering banks, guaranteed by mechanisms such as GPS and EIFO¹,
• Equity contributions from several French partners, under a project‑financing scheme,
• An equity contribution from Carbios, in addition to its in‑kind contributions (intellectual property and work carried out by Carbios for the project).

These contributions would make Carbios a minority, non‑controlling shareholder, such that the debt and financial results of Carbios 54 would not be consolidated by Carbios.

If finalized, this structure would cover the estimated construction cost of the plant estimated at €230 million, as well as all costs related to the start-up of the project².

The objective of the stakeholders involved in the project is to finalize the various components of this financing in the coming weeks, with a view to closing the deal by Q3 2026.

Amid French and European regulatory frameworks that increasingly support chemical recycling^3, Carbios is confident in its ability to conclude new pre‑sales contracts for products from the Longlaville plant and reach 70% of the future site’s production capacity in the coming months.

In light of these developments, Carbios’ Board of Directors has approved the continuation of discussions regarding the structuring of the financing required to resume the project, with a view to achieving a start of production at the Longlaville plant by H1 2028, subject to the finalization of the project.

2. Governance Update

To support the successful execution of Carbios’ development projects, including the Longlaville project and the partnership with Wankai, the Board of Directors has appointed Benoît Grenot as Deputy Chief Executive Officer.

“We are delighted to welcome Benoît Grenot to the Company: his leadership, international experience, particularly in China, and strong operational discipline will be key assets in finalizing the remaining financing steps for the Longlaville project and ensuring the long‑term success of the strategic partnership with Wankai.” - Isabelle Parize, Chairwoman of Carbios’ Board of Directors, and Vincent Kamel, Chief Executive Officer of Carbios.

"I am fully aware of the honor and responsibility of supporting Carbios at this pivotal stage of its development, and I am committed to bringing all my expertise and know‑how to these strategic projects. I am convinced of Carbios’ value and of the potential of its technologies to rethink the lifecycle of plastics.” - Benoît Grenot, Deputy CEO.

Benoît Grenot, a graduate engineer from the École des Mines de Paris, led Baikowski (a specialty chemicals group operating in Europe, the United States, and Japan) for more than ten years, where he implemented a strategy focused on value creation, innovation, and international expansion. Prior to that, he held operational management positions abroad, notably in China within the Saint‑Gobain Group, strengthening his expertise in industrial markets and materials value chains.
