Banca Monte dei Paschi di Siena has secured 62.3 per cent of Mediobanca's equity, according to provisional results at the close of the acceptance period on 8 September 2025, for its acquisition offer, which was valued at approximately EUR 16 billion, equivalent to around USD 19 billion.
FROM ALL-SHARE OFFER TO CONTROLLING STAKE
MPS's initial proposal was structured as a pure share exchange. On 2 September, MPS revised the offer to include EUR 0.90 per share in cash (about EUR 750 million in total) and waived its two-thirds acceptance condition.
Mediobanca is a Milan-based investment bank whose business includes corporate advisory services, wealth management, consumer credit through Compass, and a stake of about 13% in the insurer Generali.
With 62.3 per cent of Mediobanca's equity now in hand, MPS holds a controlling interest.
