Carbios provides an update on the financing of its Longlaville plant project

• Carbios reaffirms its commitment to building the Longlaville plant.
• Significant milestones have been achieved toward securing the project’s financing.
• While significant progress has been made, the previously announced target of achieving financial close by September 30, 2026, will not be met; Carbios will keep the market regularly informed of further developments.
  
  

Clermont-Ferrand (France), 3 August 2026 (6:00 p.m. CEST). CARBIOS (Euronext Growth Paris: ALCRB) today provides an update on the financing of its Longlaville plant construction project.

Since its press release of March 30, 2026¹, Carbios has achieved significant milestones in securing financing for the project. In particular, several banking partners have already obtained approval from their respective credit committees, marking a major step forward in the financing process.

Given the highly innovative and first-of-its-kind nature of the Longlaville project, which involves multiple stakeholders, some parties continue to conduct their due diligence work. As a result, the ongoing review process will not allow the Company to meet its previously announced target of achieving financial close by September 30, 2026. This consequently postpones the expected timeline for the start of production at the plant².

Carbios remains fully committed and confident in its ability to secure the conditions necessary to finalize the financing of the Longlaville plant and will provide the market with a further update when it reports its half-year results on September 24, 2026.
