Avantium successfully raises €45 million to accelerate the global transition to renewable and circular plastics

AMSTERDAM, 14 April 2022, 17:35 hrs CET - Avantium N.V. (the "Company" or "Avantium") announces the successful completion of its capital increase by means of a public offering of Avantium shares (the "Offer Shares") with a priority allocation period for its existing shareholders, a retail offering and a private placement (the "Offering"), for an amount of €45 million. The successful completion will allow Avantium to advance its plantMEG™ technology towards commercialisation and develop its biorefinery and CO2-based chemicals, and its other environmentally friendly polymer-related technologies.

Results of the Offering

• • The Offering generated strong interest from local and international institutional investors and Dutch retail investors, with total demand in terms of the Offering exceeding the available €45 million.

• • The final offer price for the Priority Allocation Offering, Retail Offering and Private Placement has been set at €4.00 per Offer Share.

• • Based on the final offer price of €4.00 per Offer Share, Avantium will issue 11,250,000 new shares, or c. 36% of the issued share capital of Avantium.

• • To compensate for the dilutive effect of this capital raise, the number of warrants issued to the consortium of lenders, comprising ABN AMRO Bank, ING Bank, Rabobank and Invest-NL, will increase from 2.84 million warrants to 3.86 million warrants. The warrants were granted to the lenders as part of the debt financing package of €90 million for the FDCA (furandicarboxylic acid) Flagship Plant.

• • Net proceeds will be used to (i) further develop plantMEG™ technology and to scale-up towards further commercialisation via technology licensing, (ii) further develop biorefinery and CO2 - based chemicals and environmentally friendly polymer-related technologies, as well as to assess economic feasibility and scale-up towards further commercialisation and (iii) for general corporate purposes, working capital and overall funding.

Tom van Aken, Chief Executive Officer of Avantium, comments: "The success of this capital raise positions Avantium to advance our innovative plantMEG™ technology towards commercialisation. We are pleased with the interest received from institutional and retail investors, both existing and new shareholders, and I would like to thank all investors for their trust and confidence in our business and commercialisation strategy. We are looking forward to deploying this capital and bringing our technologies to the next industrial phases."

Reasons for the Offering and use of proceeds

The reason for the Offering is to enable the Company to cover its existing expenses and to establish a reserve for the future and ongoing expenses of the Company, including for investments in the commercialisation of Avantium's technology programmes, such as its portfolio of technologies beyond YXY® Technology, being the plantMEG™ technology and the biorefinery and CO2-based chemicals and environmentally friendly polymer related technologies, and for general corporate purposes, working capital and overall funding.

The Company currently anticipates using the net proceeds of the Offering as follows:

• • 60% of the net proceeds of the Offering to further develop plantMEG™ technology (Ray Technology™) and to scale-up towards further commercialisation via technology licensing;

• • 10% of the net proceeds of the Offering to further develop biorefinery (Dawn Technology™) and CO2-based chemicals and environmentally friendly polymer related technologies (Volta Technology) as well as to assess economic feasibility and scale-up towards further commercialisation; and

• • 30% of the net proceeds of the Offering for general corporate purposes, working capital and overall funding.

Based on Avantium's current business plan, the current cash resources together with the net proceeds from the Offering should enable the Company to fund its working capital for the next 3 years and to reach its next significant operational and industrial milestones, including the commissioning of the FDCA Flagship Plant in 2024 and the final investment decision (expected in 2024) for the construction of the first commercial plant for the production of plantMEG™ and plantMPG™ using Ray Technology™, jointly with Cosun Beet Company.

About Avantium

Avantium is a leading technology development company and a forerunner in renewable chemistry. Avantium develops novel technologies based on renewable carbon sources as an alternative to fossil-based chemicals and plastics. The Company currently has three technologies at pilot and demonstration phase. The most advanced technology is the YXY® plant-to-plastics-technology that catalytically converts plant-based sugars into FDCA (furandicarboxylic acid), the key building block for the sustainable plastic PEF (polyethylene furanoate). Avantium has successfully demonstrated the YXY® Technology at its pilot plant in Geleen, the Netherlands, and will commence construction of the world's first commercial plant for large-scale production of PEF in 2022 at its FDCA Flagship Plant in Delfzijl, the Netherlands. The second technology is Ray Technology™ which catalytically converts industrial sugars to plantMEG™ (mono-ethylene glycol) and plantMPG™ (mono-propylene glycol). Avantium is scaling up its Ray Technology™ and the demonstration plant in Delfzijl, the Netherlands opened in November 2019. The third technology is called the Dawn Technology™ thatconverts non-food biomass into industrial sugars and lignin in order to transition the chemicals and materials industries to non-fossil resources. In 2018, Avantium opened the Dawn Technology™ pilot biorefinery in Delfzijl, the Netherlands. In addition to developing and commercialising renewable chemistry technologies, the Company also provides advanced catalysis R&D services and systems to customers in the refinery and chemical industries. Avantium works in partnership with like-minded companies around the globe to create revolutionary renewable chemistry solutions from invention to commercial scale.

Avantium's shares are listed on Euronext Amsterdam and Euronext Brussels (symbol: AVTX). Its offices and headquarters are in Amsterdam, the Netherlands.
