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. 

We anticipate commercial operations to begin in the first quarter of 2026, bringing us to the exciting moment when our 100% plant-based and circular material, PEF - branded as releaf^® - will reach consumers and become a true commercial reality. This is backed by strong commercial traction, with 20 partners already committed through signed offtake agreements from our FDCA Flagship Plant. This progress is made possible by broad support from our longstanding shareholders, public partners and other stakeholders. Their support reflects deep confidence in our FDCA/PEF technology and our mission to lead the transition to renewable and circular chemistry.  

This equity raise is a key part of the comprehensive funding package announced on 12 August 2025. Along with other funding initiatives, this equity raise is expected to cover Avantium’s financial needs and help keep the Company well-funded until it reaches group-level EBITDA break-even, which is expected in 2027. We are grateful for the continued trust of our longstanding shareholders and are especially pleased with the continued support of Invest-NL as well as the support of the Dutch State, represented by the Ministry of Climate Policy and Green Growth (Ministerie van Klimaat en Groene Groei), which has committed to act as one of the underwriters for this equity raise and has agreed to subscribe via private placement for any portion of the €15 million underwriting not used in the offering. We warmly welcome both our existing shareholders and new investors who share our ambition to build a more sustainable future through innovation.”

Information to distributors  

Solely for the purposes of the product governance requirements contained within: (a) EU Directive 2014/65/EU on markets in financial instruments, as amended (MiFID II); (b) sections 9 and 10 of Commission Delegated Directive (EU) 2017/593 supplementing MiFID II; and (c) local implementing measures (together, the MiFID II Product Governance Requirements), and disclaiming all and any liability, whether arising in tort, contract or otherwise, which any "manufacturer" (for the purposes of the MiFID II Product Governance Requirements) may otherwise have with respect thereto, the Securities subject to the Offering have been subject to a product approval process, which has determined that such Securities are: (i) compatible with an end target market of retail investors and investors who meet the criteria of professional clients and eligible counterparties, each as defined in MiFID II; and (ii) eligible for distribution through all distribution channels as are permitted by MiFID II (the Target Market Assessment).  

Notwithstanding the Target Market Assessment, "distributors" (for the purposes of the MiFID II Product Governance Requirements) should note that: the price of the Securities may decline and investors could lose all or part of their investment; the Securities offer no guaranteed income and no capital protection; and an investment in the Securities is compatible only with investors who do not need a guaranteed income or capital protection, who (either alone or in conjunction with an appropriate financial or other adviser) are capable of evaluating the merits and risks of such an investment and who have sufficient resources to be able to bear any losses that may result therefrom. The Target Market Assessment is without prejudice to the requirements of any contractual, legal or regulatory selling restrictions in relation to the Offering.  

For the avoidance of doubt, the Target Market Assessment does not constitute: (a) an assessment of suitability or appropriateness for the purposes of MiFID II; or (b) a recommendation to any investor or group of investors to invest in, or purchase, or take any other action whatsoever with respect to the Securities.  

Each distributor is responsible for undertaking its own target market assessment in respect of the Securities and determining appropriate distribution channels.
