Shares of Banca Monte dei Paschi di Siena (MPS) soared more than 10% on Monday after Intesa Sanpaolo made an unsolicited €30.6 billion cash-and-share offer, disrupting MPS's existing merger negotiations with Banco BPM. The stock climbed 10.91% to €9.921 in regular Euronext Milan trading by mid-morning, outperforming a broadly weaker European market.
The bid, which values MPS at a 12.5% premium over its closing price on June 5, consists of 16 new Intesa shares for every 10 MPS shares plus €1 in cash per MPS share. Italian takeover rules now prevent MPS from finalizing a deal with Banco BPM without shareholder approval, effectively blocking that merger path unless a better offer emerges or regulatory hurdles are cleared.
Intesa's move comes as a surprise, given that MPS had been in advanced talks with Banco BPM. Intesa CEO Carlo Messina has previously described Italy's banking M&A landscape as “the Wild West,” signaling his willingness to pursue aggressive consolidation. The offer includes a pre-arranged agreement with Unipol to sell off the MPS brand, approximately 635 branches, and most of the Siena headquarters for an estimated €3.0 billion to €3.5 billion. Unipol, the largest investor in BPER Banca, may help address antitrust concerns by absorbing these assets.
Intesa plans to retain Mediobanca, its own brand, and roughly 625 MPS branches. If the deal goes through, the combined entity is projected to have a market value of €126 billion and target net income of €16 billion by 2029. However, execution risks are high. 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.”
MPS's role in Italian finance extends beyond its own balance sheet. Last year, it acquired a stake in Mediobanca, which gave it indirect exposure to Generali, Italy's largest insurer. Intesa's board has also approved the purchase of a 3.01% stake in Generali as part of the MPS transaction, describing it as a temporary financial investment that would allow equity-method accounting and enable Intesa to book a share of Generali's profits if the takeover succeeds.
Despite the premium, the gap between MPS's market price and Intesa's offer suggests investors remain skeptical about a smooth completion. The deal faces multiple hurdles: regulatory approval for the branch sale, shareholder votes, and the risk that Banco BPM may counter with a more attractive proposal. Intesa estimates pre-tax charges of roughly €2.1 billion from restructuring, including cost cuts and revenue improvements, which add to the uncertainty.
MPS is trading more like a bid stock than an independent bank, reflecting the market's view that its future hinges on this contest. The Siena board, regulators, and major shareholders will ultimately decide whether Intesa's Monday move becomes a formal takeover or whether Banco BPM's merger pitch can sustain enough momentum—both financially and politically—to prolong the battle.
European markets were broadly lower on the day, with the STOXX 600 down 0.7% to a two-week low. Intesa shares fell 4.1% as investors weighed the costs and risks of the acquisition. The outcome will be closely watched as a bellwether for further consolidation in the Italian banking sector.
