About HAFFNER PARTICIPATION SAS SAS
Haffner Participation SAS is the controlling vehicle associated with Marc Haffner, co-founder of Haffner Energy and chairman of Haffner Participation SAS. Within the group’s governance framework, it plays a central role as reference shareholder and strategic anchor for the listed company. The most recent public disclosures indicate that Haffner Participation SAS remains Haffner Energy’s principal shareholder, holding a meaningful stake and voting power, which underlines its lasting influence over the company’s direction. The background linked to Haffner Participation SAS is rooted in a long-term entrepreneurial story focused on industrial decarbonization. Haffner Energy states that it was co-founded by Marc and Philippe Haffner more than 30 years ago, building expertise in low-carbon energy solutions derived from biomass residues. That expertise has led to patented technologies used to produce sustainable aviation fuel, renewable gas, hydrogen and methanol, as well as biogenic CO2 and biochar. From a governance standpoint, Haffner Participation SAS, represented by Marc Haffner, stands out as a vehicle of continuity and strategic support. In 2025, Haffner Energy clarified that some share disposals carried out by Haffner Participation SAS were driven by external financing constraints rather than operational issues, while reiterating the main shareholder’s long-term support for the strategy implemented by management. This episode illustrates a disciplined approach to ownership management, combining industrial commitment, capital stewardship and support for the company’s growth ambitions as a listed issuer on Euronext Growth. For a corporate and investor audience, Haffner Participation SAS therefore represents shareholder continuity, a long-term industrial vision and a family-led commitment to Haffner Energy’s energy-transition mission. Its role is especially notable in an environment where technological credibility, financial discipline and strategic consistency are essential drivers of value creation.
