CARBIOS maintains its commitment to build the Longlaville plant and adjusts its timeline

• CARBIOS reaffirms its ambition to pursue the Longlaville plant construction project and postpones the timeline by three-month.
• The plant construction project is supported by:
  – Pre-commercialization contracts covering close to 50% of the production capacity of the future industrial site in Longlaville.
  – Significant progress in structuring the additional financing required to restart the project. 
  – Secured public funding of €42.5 million. 
  A small portion¹ of the financing still needs to be secured before the project can move forward. CARBIOS aims to achieve this by the end of the first quarter of 2026.
• With over €55 million in projected available cash at the end of 2025², CARBIOS has visibility on its financing horizon beyond the next twelve months while maintaining its strategic capabilities and a rigorous control over expenses.
• CARBIOS remains fully committed to the commercialization of licenses for its technology, and following the successful contract with Wankai, ambitions to sign other licenses in Europe, North America and South America.

CARBIOS (Euronext Growth Paris: ALCRB) reaffirms its ambition to pursue the Longlaville plant construction project, by rescheduling the timeline with a three-month adjustment.

In 2025, CARBIOS signed pre-commercialization contracts covering close to 50% of the production capacity of the future industrial site in Longlaville and is working to secure commitments to reach 70% in the near term. These multiple commercial agreements concluded in the cosmetics, beverage, and tire textile filament industries, confirm the strong market traction for biorecycled PET produced using the technology designed and developed by CARBIOS.

The pre-commercialization progress has been instrumental in driving forward the structuring of the financing needed to resume construction project of this first PET biorecycling plant in France and to cover the main portion required to finance the plant project³. It is expected that the plant will be financially independent from CARBIOS (non-recourse financing on CARBIOS.)

The financing of this industrial project is based on private financing (debt and equity) and on confirmed public aid amounting to 42.5 million euros.

A small portion¹ of the financing still needs to be secured before the project can move forward. CARBIOS aims to achieve this by the end of the first quarter of 2026. If this is the case, the plant should be commissioned during the first half of 2028.

CARBIOS remains fully committed to commercializing licenses for its technology, with an initial strategic partnership agreement signed on 2 December 2025 with Wankai New Materials to deploy its PET biorecycling technology in Asia⁴. In addition, the Company aims to commercialize new licenses in Europe, as well as in North and South America.
