Pherecydes Pharma lists on Euronext Growth Paris to accelerate its fight against antibiotic-resistant bacteria



Paris 5 February 2021 – Euronext today congratulates Pherecydes Pharma, the French biotech company specialising in the treatment of bacterial infections, especially those that are complicated and/or resistant to antibiotics, on its listing on Euronext Growth Paris (ticker code: ALPHE).

Pherecydes Pharma was created in 2006. Its headquarters are in Nantes, and its research and development centre is based in Romainville. The company develops treatments based on the use of bacteriophage viruses, or phages, to fight bacterial infections that do not respond to antibiotic treatment. According to the World Health Organisation, antibiotic resistance could be responsible for more than 10 million deaths per year by 2050[1]. The capital raised will allow Pherecydes Pharma to conduct further clinical tests and potentially to make the medicines available through temporary authorisations for use (TAU) from the second half of 2021.

Pherecydes Pharma was listed through the admission to trading of the 5,824,253 shares making up its equity, including 1,333,265 new shares issued under a Public Offering[2], after the full exercise of the extension option.

The admission and issue price was set at €6.00 per share. Market capitalisation was €34.9 million on the day of listing. The offering raised €8 million altogether.

The offering was a resounding success with international institutional and individual investors, and was oversubscribed 4 times, with a total demand of €28.1 million.

Guy-Charles Fanneau de La Horie, CEO of Pherecydes Pharma, said: “The IPO of Pherecydes Pharma marks a new chapter in the life of the company, and I would like to thank all investors that have contributed to the great success of this operation. Thanks to their support, we are more determined than ever to continue our growth and establish our leadership in the field of phagotherapy.”
