Vitry-le-François, France – September 4, 2025, 6:00 pm (CET)

Haffner Energy has taken note of the questions raised by its shareholders regarding share disposals by Haffner Participation SAS in particular.

Haffner Participation SAS, Haffner Energy’s main shareholder, sold 1.2 million shares (representing 1.93% of the share capital) between May and August 2025. This transaction was necessitated by Haffner Participation's need to repay a short-term bank loan, which has now been finalized. It was also prompted by the contribution to the financing of a personal project led by Marc Haffner, Chairman of Haffner Participation SAS.

Furthermore, the transaction was carried out in strict compliance with the retention commitment made by Haffner Participation during the capital increase of April 2025, which covered all the shares held by Haffner Participation SAS prior to this fundraising.

As at August 31, 2025, Haffner Participation SAS retains 18,999,000 shares, representing 30.55% of the capital and 39.04% of the theoretical voting rights, thus remaining the main shareholder of Haffner Energy. At the same date, Haffner Energy's share capital comprised 62,182,201 shares, representing 94,318,782 theoretical voting rights.

Marc Haffner, Co-Founder of Haffner Energy and Chairman of Haffner Participation SAS, stated that:

“The share disposals of Haffner Participation SAS, strictly linked to economic constraints external to Haffner Energy, are now complete. Haffner Participation SAS reaffirms its ongoing commitment and confidence as the main shareholder of Haffner Energy to pursue the strategy implemented by its executive team.”
