FDI screening in Spain

Law 19/2003, developed by Royal Decree 571/2023, requires prior authorisation when non-EU/EFTA investors — and in certain cases intra-EU ones — acquire significant stakes in strategic sectors: energy, critical technologies and inputs, infrastructure, media or data-sensitive businesses, among others. The consequence: the screening question must be answered at the offer stage, because it shapes conditions precedent, timetable and sometimes deal perimeter.

The procedure runs on statutory deadlines that depend on the route taken, and well-prepared files move materially faster. The consequence: clearance belongs on the critical path of the SPA from day one — with the filing drafted in parallel to due diligence — so the authorisation arrives inside the deal calendar rather than stretching it.

The foreign-investment rules deprive the unauthorised transaction of effect until it is cleared, and back this with significant fines. The consequence: sellers should not accept timetables that ignore the filing, and buyers should treat FDI analysis as a gating workstream — restructuring the perimeter early is cheaper than unwinding a closing.
