CARBIOS (Paris:ALCRB) (Euronext Growth Paris: ALCRB – ISIN: FR0011648716), (the "Company"), a pioneer in the development of bio-industrial solutions for the lifecycle of plastic and textile polymers, announces today the launch of a capital increase without preferential subscription rights for a category of beneficiaries, pursuant to the 13^th resolution of the Combined General Meeting of June 19, 2019 and the Board of Directors' authorization dated June 20 and 24, 2019 (the "Transaction"). The target amount of the Transaction is 13 million euros, a dilution representing approximately 27.27%¹. The number of shares, the amount raised, and the exact dilution will be mentioned in the press release announcing the results of the Transaction.

Regarding the category of beneficiaries without preferential subscription rights (investment companies and investment funds under French law or foreign law investing in a similar or complementary segment to that of CARBIOS), the funds will only be raised from French and international qualified investors, except for the United States, Canada, Australia, and Japan.

The funds raised will be used by CARBIOS as follows:

• Approximately 75% for financing an industrial PET biorecycling demonstration plant² ; and
• Approximately 25% for the Company's ongoing financing.

In this regard, the Company indicates that the estimated release dates of the PLA³ and the PET to end-use customers are now 2020 and 2023, respectively, instead of 2019 and 2021⁴.

The Transaction will take place by way of an accelerated bookbuilding process, after which the number and price of new shares issued will be set. The accelerated bookbuilding begins immediately and should close before 6:00 p.m. on June 25, 2019, subject to any early closure or extension.

The Company will announce the results of the Transaction on June 25, 2019, in a press release published after market close. Pending this publication, CARBIOS asked Euronext Paris to suspend the trading of its stock (ISIN FR0011648716 - ALCRB) as of June 24, 2019 after market close.

Copernicus AM, Michelin Venture and L’Oréal via its capital-investment fund BOLD (Business Opportunities for L'Oréal Development) and Truffle Capital have committed to subscribe to the capital increase for a total of 10.5 million euros, under certain conditions, notably of price and / or minimum amount of the Transaction. These supports are strong markers of the Company's established legitimacy and its management team.

In the context of this capital increase, the Company has made a lock-up commitment for 90 calendar days after the settlement and delivery date of the issue.

The settlement and delivery date of the new shares would be June 28, 2019.

The new shares will carry immediate dividend and voting rights and will be listed on the Euronext Growth Paris market under ISIN FR0011648716 - ALCRB.

Pursuant to Article 211-3 of the General Regulation of the French financial market authority (AMF), the offering of the Company's shares under this capital increase carried out for a specific category of beneficiaries will not result in a prospectus submitted for approval by the AMF. Detailed information about the Company, specifically its activity, its earnings, and the corresponding risk factors appears in the Company's 2018 Registration Document filed with the AMF on April 8, 2019 under number D.19-0287, which may be consulted, along with the Company's other regulated information and all its press releases, on its website (www.carbios.fr).

About Carbios:

CARBIOS is a green chemistry company whose innovations provide solutions to the environmental and sustainable development issues manufacturers currently face. Since its founding in 2011, the company has developed two industrial-scale biological processes for the biological breakdown and recycling of polymers. These unique innovations help optimize the performance and life cycle of plastics and textiles by capitalizing on the properties of specially selected enzymes. CARBIOS’s economic growth model is based on the industrial roll-out and sale of its products, enzymes, technologies and biological processes through direct licence agreements or joint ventures, to major players in the fields to whom they would most benefit. To that end, CARBIOS founded the joint venture CARBIOLICE in 2016, in partnership with Limagrain Céréales Ingrédients and the SPI fund, run by Bpifrance. This company, in which CARBIOS holds a controlling share, will market the first technology licensed by CARBIOS by producing enzyme pellets used in the production of biodegradable and bio-sourced plastics. Since its founding, CARBIOS has been backed by Truffle Capital, a European investment capital player. CARBIOS qualifies as an "Innovative Company” according to Bpifrance, which makes the company’s shares eligible for inclusion in innovation-focused mutual funds (FCPIs).
