  • 34th listing of a cleantech company on Euronext in 2021

Paris – 14 July 2021 – Euronext today congratulates Enogia, a company expert in micro-turbomachinery for the energy transition, on its listing on Euronext Growth Paris (ticker code: ALENO).

Enogia develops, manufactures, and markets a unique and patented micro-turbine technology for the energy transition. A French leader in the conversion of heat to electricity, Enogia also develops its know-how in the decarbonised hydrogen market and, more specifically, in hydrogen fuel cells (HFC). Enogia's sustainable approach is integral to the development of its energy activities and its growth. As part of its planned Initial Public Offering (IPO), the company requested an extra-financial rating from specialist agency EthiFinance. This rating places Enogia at an "Advanced" level of performance, highlighting a high level of maturity in terms of Environmental, Social and Governance (ESG) criteria.

Enogia was listed through the admission to trading of the 3,858,932 shares making up its equity, 954,032 of which were new shares issued under a Global Offering[1], before the potential exercise of the over-allotment option.

The admission and issue price of Enogia shares was set at €11.60 per share. Market capitalisation was €44.8 million on the day of listing. The offering raised €11.1 million altogether.

Arthur Leroux, CEO and Chairman of Enogia, said: “We are delighted with the success of our IPO, a major new step in Enogia’s story. The energy transition market is expanding rapidly throughout the world. Enogia is a major player in this market. We are already the French leader in the conversion of waste heat into electricity, and our ambition for the future is to become one of the major players in the hydrogen market. Since our creation, more than 120 Enogia micro-turbomachines have been installed in over 25 countries. Driven by the growing demand of the energy transition markets and thanks to the funds raised through the IPO, we will be able to accelerate our deployment by concentrating on continued investment in R&D, accelerating our commercial success and increasing the power of our production tools.”
