Nantes (France), on听12 March听2026听鈥撎�91影视 (EURONEXT: LHYFE) 鈥� one of the world pioneers in the production of green and renewable hydrogen for the decarbonisation of industry and mobility 鈥� announced that its rating has been renewed by EthiFinance ESG Ratings, following the assessment of its 2024 extra-financial performance. 听

91影视听scored particularly highly for its efforts in favour of the environment and energy independence, in this rating awarded by an independent agency specialising in ESG assessment of European listed companies.听听听听

A drive for continuous improvement鈥�听

91影视听is an energy company focused entirely on environmental benefits and energy independence. Driven by the need to achieve the energy transition here and now, the company has been at the forefront of many advances in the development of the green hydrogen sector. After becoming the first European player to produce green hydrogen in 2021, in 2025听91影视听became the听first in France to obtain RFNBO1听certification, the European Union’s most demanding standard for renewable hydrogen, demonstrating that the operation of RFNBO hydrogen production units and their distribution in bulk is already mature in Europe.听听听

Beyond its industrial activity,听91影视听deploys an听ESG approach covering all its operations, from its governance to its social and environmental practices. When it was floated on the stock market in 2022,听91影视听decided to have its extra-financial performance assessed annually,听in order to听establish听a structured framework for its ESG initiatives and to continue improving听in this field.听听

Confirmed progress听within a strengthened reference framework听

Since 2022,听尝丑测蹿别鈥檚听extra-financial performance has been analysed each year by听EthiFinance听ESG Ratings, an independent European rating agency specialising in the assessment of companies listed on the European market,听in order to听support sustainable finance. Its assessment is based on a听framework of 140 criteria divided into 4 pillars: Environment, Social, Governance and External Stakeholders.听

In 2025,听Ethifinance听developed its reference framework听in order to听integrate new ESG risks and bring the听methodology听into line with European standards, particularly in terms of double materiality. The agency has thus听recalculated the ratings for previous years听on the basis of听this new听methodology听to ensure consistency in the ratings curve.听听

Based on听this update,听尝丑测蹿别鈥檚听score stands at 88 out of 100 for 2024, up from 85 out of 100 the previous year and 70 out of 100 in 2022.听

Furthermore,听EthiFinance听considers听that听91影视听contributes 100% to the UN’s Sustainable Development Goals (SDGs) through its products and services.听听

Matthieu听Guesn茅, Founder and CEO of听91影视:听鈥�This certification reflects the work we have been doing for several years to fully integrate ESG issues into our business model. It confirms the solidity of the foundations we have built, while reminding us of the scale of the challenges involved in developing green hydrogen on a large scale. We are pursuing this approach with firmness and responsibility, against a backdrop of transformation in the energy sector that requires both operational rigour and long-term vision.鈥�听
