Paris, July 10th, 2015 – Bryan, Garnier & Co, the pan-European investment bank for growth companies, announces the successful €13.2m IPO of Amoéba, producer of a “green” biocide aiming to substitute the chemical biocides for water treatment in industrial environments. Bryan, Garnier & Co acted as Global Coordinator and Joint Bookrunner, strengthening its leadership position in the Cleantech & Renewables sector.  

Amoéba, a producer of “green” Biocide aiming to substitute the chemical biocides currently used in industrial water treatment, has successfully completed its IPO on Euronext Paris. Bryan, Garnier & Co acted as Global Coordinator and Joint Bookrunner for this IPO. The transaction was oversubscribed with  over 40 institutional investors. 

The final offer price was set at €8.30 per share resulting in a market capitalization at IPO of approximately €44,5 million. Amoéba will issue 1,592,307 new shares including the fully exercised extension option (207,692 shares). 81% of the placement was subscribed by institutional investors and 19% by retail investors.

With strong patents and demonstrated production scalability, Amoéba is ideally positioned to substitute chemical biocides in industrial water treatment. The proceeds from the IPO will finance the industrial rollout and commercial developments of Amoéba in Europe and North America.

Olivier Beaudouin, Partner leading the Cleantech franchise commented : “Our deep knowledge of the Cleantech and Biotech sectors have enabled us to identify early on Amoéba as a unique company at the crossroads between those two sectors. The company’s operational milestones, low capex technology and non-disruptive implementation with industrial clients have been decisive factors to convince investors  in challenging market conditions due to the recent Greek events. Following the €32m IPO of McPhy and €115m capital increase for Voltalia, Bryan Garnier & Co confirms its leading position as an advisor to Cleantech companies on European capital markets”.
