Clermont-Ferrand (France), 30 March 2026 (5:45 pm CEST). Carbios (Euronext Growth Paris : ALCRB) 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 recycling³, 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.

Isabelle Parize, Chairwoman of Carbios’ Board of Directors, and Vincent Kamel, Chief Executive Officer of Carbios: “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.”

Benoît Grenot, Deputy CEO: “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, 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.

3. Financial Situation

Carbios has a solid cash position, with around €60 million at the end of December 2025, enabling the company to meet its operating expenses beyond the next 12 months.

The projected cash consumption for 2026 (excluding the Longlaville project) is estimated at around €20 million. Carbios continues to optimize its operating costs.

Carbios’ 2025 annual results are expected to be published on 17 April 2026.

4. Update on Legal Proceedings

Following the departure of its former executive, Mr. Philippe Pouletty, two legal actions have been initiated against Carbios and its management: a first action through direct summons related to the remuneration of the Chairwoman and the Chief Executive Officer, and a second action seeking access to certain company documents.

The company intends to defend itself vigorously against these unfounded allegations.

A complaint against persons unknown for false accusation has been filed by Carbios with the Public Prosecutor at the Lyon Judicial Court, along with a motion for retraction to obtain the return of the documents that were seized.

Carbios’ management and all members of the Board of Directors deplore the attacks from this former executive who, for personal reasons connected to the circumstances of his departure—following facts that could be characterized as harassment, repeats threats, and attempts at intimidation—acts solely with the intention of harming the Company and its leadership.

The Board of Directors has unanimously reaffirmed its full and complete support for the Company’s management and confirms its total confidence in the executive team to continue implementing the strategy underway.
