In 1921, the Banca Italiana di Sconto, which backed the Ing. Nicola Romeo & Co, went broke and the government needed to support the industrial companies involved, among which was Alfa Romeo, through the "Consorzio per Sovvenzioni sui Valori Industriali".
In 1925, the railway activities were separated from the Romeo company, and in 1928, Nicola Romeo left. In 1933, the state ownership was reorganized under the banner of the Istituto per la Ricostruzione Industriale (IRI) by Benito Mussolini's government, which then had effective control.
