MILAN, June 8, 2026, 11:03 CEST
Banca Monte dei Paschi di Siena shares surged in Milan on Monday after Intesa Sanpaolo dropped an unsolicited €30.6 billion bid, disrupting Banco BPM’s own talks over a merger with the bank. The stock sat at 9.921 euros, up 10.91%, at 11:03 a.m. local in regular Euronext Milan trading. Borsa Italiana holds continuous trading from 0900 to 1730, with no closure for the cash market on June 8 according to its 2026 calendar.
MPS isn’t only the bank Italy bailed out in 2017 and sent back to private investors. Its Mediobanca deal last year also gave it a path into Generali, the big insurer that sits at the heart of Italy’s finance world. CEO Luigi Lovaglio put it this way: “All roads lead to Siena.” Reuters
Intesa’s bid shifts the weekend dynamics. Reuters said that Italian takeover rules now block MPS from signing off on a Banco BPM deal without shareholder approval after Intesa’s formal offer. Intesa CEO Carlo Messina earlier described Italy’s bank M&A scene as “the Wild West.” Reuters
Intesa is offering MPS holders 16 new Intesa shares for every 10 MPS shares, and 1 euro in cash for each MPS share in a cash-and-share deal. The bank put the premium at 12.5% over MPS’s June 5 close. The offer includes an agreement with Unipol to sell off the MPS brand, about 635 branches, and most of the Siena headquarters for roughly 3.0 billion to 3.5 billion euros.
Intesa is holding a tight line on its deal map. The bank wants to hold on to Mediobanca, its brand, and keep roughly 625 MPS branches. Unipol, which is the top investor in BPER Banca, could help the group with antitrust issues as regulators look at whether the transaction would lead to too much market concentration. If Intesa pulls this off, it says the merged bank will be worth 126 billion euros and will aim for 16 billion euros in net income by 2029.
MPS bucked the trend on a down day. Europe’s STOXX 600 lost 0.7%, hitting its lowest in two weeks. Intesa dropped 4.1% after it announced its bid. Suvi Platerink Kosonen, senior sector strategist for financials at ING Bank, called the deal “positive for Intesa Sanpaolo in the longer term” but warned of “substantial uncertainty regarding execution.” Reuters
Generali is the extra piece, maybe also the tricky one. Intesa’s board backed picking up a 3.01% stake in the insurer as part of the MPS deal. The board called it a temporary, financial move aimed at keeping equity-method accounting, which lets the bank book part of Generali’s profit if the takeover goes through.
But this deal isn’t automatic. The gap between MPS’s market price and what Intesa is offering signals investors aren’t pricing it as a done deal. The whole thing hangs on regulators approving the branch sale, shareholders going with Intesa’s offer instead of Banco BPM’s merger pitch, and management actually hitting their targets on synergies — cost cuts and revenue improvement — after roughly 2.1 billion euros in pre-tax charges, which Intesa has estimated.
MPS is still trading more like a bid stock than an independent bank. What comes next depends on whether the Siena board, regulators and main shareholders let Intesa convert Monday’s move into a formal takeover, or if Banco BPM’s pitch can hold enough force, with investors and politics, to extend the contest.
