Paris – 08 November 2021 – Euronext today congratulates MaaT Pharma, a company specialized in the research and development of microbiota biotherapies, on its listing on the regulated market of Euronext Paris (ticker code: MAAT).

Founded in 2014 and based in Lyon, MaaT Pharma is developing an innovative therapeutic approach focused on oncology through modulation of the gut microbiota. MaaT Pharma's methodology is based on its MET ("Microbiome Ecosystem Therapy") platform for the design of prospective drugs with high microbial diversity from healthy donors or produced by co-fermentation. The company is currently developing three prospective drugs, the most advanced of which is ready to enter Phase 3 clinical trials, to improve the chances of survival of patients with acute graft-versus-host disease. The IPO aims to strengthen MaaT Pharma’s development in the field of microbiota modulation in oncology, to progressively broaden its product portfolio by developing new innovative microbiota-based therapies and to build an integrated biopharmaceutical company.

MaaT Pharma was listed through the admission to trading on 8 November 2021 of the 9,514,780 shares making up its equity and of 2,333,333 new shares issued under a Global Offering[1], before the potential exercise of the over-allotment option.

The admission and issue price of MaaT Pharma shares was set at €13.5 per share. Market capitalisation was €128.4 million on the day of listing. The Initial Public Offering (IPO) raised €31.5 million altogether.

Hervé Affagard, co-founder and CEO of MaaT Pharma, said: “This IPO opens a new chapter in the history of MaaT Pharma and represents an important milestone for our sector, as it is the first listing of a company developing microbiota-based drugs in continental Europe. Our entire team would like to thank our new shareholders, both institutional and individual, as well as our historical shareholders and our ecosystem, who have chosen to contribute to our success, and whose trust honours us. The funds raised will enable us to pursue our clinical and industrial development plan and to accompany our product MaaT013 into Phase III and then towards a marketing authorisation procedure. Our ambition is to become the reference player in the world of microbiota in oncology for the benefit of millions of patients.”
