Decision of the Council of State concerning the “Bleue Lorraine” concession

2030 targets confirmed

Pontpierre, France – December 17^th, 2025 – La Française de l'Énergie (Euronext : FDE – ISIN : FR0013030152), low-carbon energy producer, takes note of the decision of the Council of State to cancel the decree of November 20^th, 2023, granting the “Bleue Lorraine” concession despite the recommendations of the State services.

This decision exclusively concerns gas present in the Lorraine subsoil that FDE anticipates producing and utilizing in Moselle, as part of the “Bleue Lorraine” concession, with a significantly lower carbon footprint than that of imported gas currently consumed in France.

The company disagrees with the decision in question and intends to protect all of its interests.

However, this decision has no impact on the Group's existing activities and does not affect the research program related to the discovery of natural hydrogen and the drilling currently underway at the Pontpierre site in Moselle, nor does it affect the recovery of mine gas in the Hauts-de-France region.

The recovery of gas from the Lorraine subsoil has not contributed to the Group's results to date.

FDE is therefore maintaining the Group's 2030 objectives and outlook.

2030 forecasts confirmed

• More than €175 m revenue
• More than €85 m EBITDA
• More than 20 million tons of CO? avoided

Next event:

H1 revenue: January 21^st, 2026 after market close

La Française de l'Énergie is eligible for the PEA and PEA-PME tax-advantaged savings plans.
