The announcement comes a few weeks after signing a conditional agreement with its lenders — ABN AMRO, ASN, ING, Invest-NL, and Rabobank to extend and amend its Senior Debt Financing Agreement.

The funding will help Avantium meet its financial needs and keep the company funded until it reaches group-level EBITDA break-even, expected in 2027.

The rights offering consists of 12,103,283 new ordinary shares, issued at a subscription ratio of 11 new shares for every 8 existing shares, at an issue price of €5.40 per share.

The price reflects a 40 per cent discount to the theoretical ex-rights price, based on the closing price of €13.95 on Euronext Amsterdam on 3 September 2025.

Cornerstone investors, including VP Capital NV, Pieter Kooi Holding B.V., and Navitas B.V., have committed €12.25M, representing 18.7 per cent of the offering.

The remaining €52.75M is fully underwritten, says the company.  

The Dutch State, represented by the Ministry of Climate Policy and Green Growth, has also committed to subscribe for any portion of its €15 million underwriting not placed in the offering via private placement.

Tom van Aken, Chief Executive Officer of Avantium, comments, “Avantium has entered a pivotal phase in its journey. The successful start-up of the sugar dehydration unit – the largest part of our FDCA Flagship Plant – as announced on 29 August 2025, marks a key technical achievement in the phased commissioning and start-up of the facility. This unit converts plant sugars into MMF, a vital intermediate in the FDCA production process, and we are proud to report that MMF is now being produced successfully. With our utility systems already operational, we are now progressing with the commissioning and start-up of the final two units. 

Commercial operations by Q1, 2026

Avantium plans to start commercial operations in the first quarter of 2026, when its 100 per cent plant-based and circular material, PEF, branded as Releaf, becomes available to consumers.

The company has already secured commitments from 20 partners through signed agreements from its FDCA Flagship Plant.

This support comes from long-standing shareholders, public partners, and other stakeholders, indicating their confidence in Avantium’s technology and objectives related to renewable and circular chemistry.

Avantium: Commercialising innovative chemistry technologies

Founded in 2000 by Claude Stoufs, Avantium is a commercial-stage company specialising in renewable and circular polymer materials.

It develops and commercialises technologies to produce materials from sustainable carbon feedstocks, such as biomass and CO2.

It’s leading YXY Technology converts plant-based sugars into FDCA (furandicarboxylic acid), the key component of the sustainable plastic PEF.

The Amsterdam company has demonstrated this technology at its pilot plant in Geleen, Netherlands.
