The transaction sparked apprehensions in Paris regarding potential foreign dominance over digital infrastructure. Consequently, the French government enforced conditions prior to approval.
NJJ Capital, an investment firm owned by telecom magnate Xavier Niel, will acquire a 10% share in Mara France, the local entity overseeing the acquisition, as a stipulation for the involvement of a French investor. EDF will maintain a minority interest and will remain a client of Exaion.
Finance Minister Roland Lescure characterized the conclusion as indicative of France’s openness to global investment while simultaneously safeguarding its strategic interests.
“In this operation, the State is progressing on two fronts: we are affirming France’s appeal for international investment while ensuring uncompromising safeguarding of our strategic interests and our technological sovereignty,” the Minister stated. A government announcement also clarified that no sensitive EDF data will be retained by Exaion following the transaction.
Exaion’s board of directors will now include members from MARA, EDF, and NJJ.
