Translated from Spanish

Ferrovial · construction · 2026-09-11
Ferrovial received a fine of 38.5 million for these monopolistic practices, a figure close to the annual tax savings it is estimated it will obtain (of up to 40 million) from its move to the Netherlands, according to calculations by Banco Sabadell.

Who read this fact

Read by GLM-4-9B Not enough to decide
