In a seismic shift for Italy’s financial sector, Monte dei Paschi di Siena (MPS) has clinched a commanding 62.3% stake in Mediobanca through its voluntary public purchase and exchange offer (OPAS), falling just short of its ambitious 66.67% target. Under CEO Luigi Lovaglio’s leadership, MPS has stormed Piazzetta Cuccia, cementing its grip on Italy’s premier investment bank and setting the stage for a transformative era in European finance.
A Strategic Triumph for MPS
Announced on September 8, 2025, the OPAS results mark a pivotal victory for MPS. The Siena-based bank, led by Lovaglio, secured 62.3% of Mediobanca’s capital, surpassing the critical 35% threshold for de facto control and edging close to the 66.67% needed for full consolidation. The offer, valued at over €16 billion with a €0.90 per share cash component, lured institutional investors and key stakeholders like Edizione (2.1%) and pension funds Enpam, Enasarco, and Cassa Forense (collectively over 5.5%).
This aggressive bid, launched on July 14, 2025, transformed from an all-share offer to include cash, costing MPS approximately €750 million. The move not only sweetened the deal but also signaled Lovaglio’s determination to reshape Italy’s banking landscape.
Lovaglio’s Vision: Scaling Piazzetta Cuccia
Luigi Lovaglio, MPS’s charismatic CEO, has been the architect of this audacious takeover. Since taking the helm in 2022, he’s steered MPS from near collapse to a powerhouse with a CET1 capital ratio of 19.6% and a €892 million half-year profit in 2025. His strategy hinges on capturing Mediobanca’s influence, including its significant stake in insurer Generali, to create a “third competitive force” in Italian banking.
“We’re building a great brand,” Lovaglio told Bloomberg TV, expressing confidence in exceeding the 66% mark before the offer’s reopening period from September 16–22, 2025. He envisions synergies worth €700 million and tax benefits of €2.9 billion over six years, despite Mediobanca’s board rejecting the offer as “hostile” and “not convenient.”
Mediobanca’s Resistance and Market Reaction
Mediobanca’s leadership, led by CEO Alberto Nagel, fought back fiercely, labeling the OPAS as opportunistic and advancing a shareholder meeting on Banca Generali to August 21 to counter MPS’s momentum. Nagel criticized the 35% threshold as a sign of “opacità” (opacity), arguing it showed MPS’s desperation to close the deal at any cost.
Despite the pushback, the market responded cautiously. On September 3, both MPS and Mediobanca shares dipped 1.9% at Piazza Affari, reflecting investor uncertainty. Yet, analysts like those at Deutsche Bank see “strong strategic rationale” in the deal, citing diversification and profitability potential, with a “Buy” rating on MPS at €9.2 per share.
U.S. Relevance: A Ripple Effect Across the Atlantic
While rooted in Italy, this deal carries weight for U.S. investors and markets. Mediobanca’s global reach, particularly through its Generali stake, influences insurance and financial sectors worldwide. American institutional investors, holding roughly 30% of Mediobanca, played a pivotal role in the OPAS’s success, signaling confidence in Lovaglio’s vision. A stronger MPS-Mediobanca could enhance cross-border M&A, impacting U.S. firms eyeing European expansion.
Economically, the deal underscores consolidation trends relevant to Wall Street. With U.S. banks like JPMorgan advising MPS, the transaction highlights transatlantic collaboration in high-stakes finance. However, it also raises concerns about concentrated financial power, mirroring U.S. debates over “too big to fail” institutions, potentially drawing scrutiny from regulators like the SEC.
Public and Expert Reactions
The financial world is abuzz. On X, analysts praise Lovaglio’s tenacity, with one user posting, “MPS at 62.3% is a masterstroke—Piazzetta Cuccia is no longer untouchable.” Others express skepticism, noting Mediobanca’s entrenched resistance and potential governance clashes. “Lovaglio wants a new CEO for Mediobanca, but Nagel won’t go quietly,” a Milan-based banker tweeted.
Experts like those at Equita, Mediobanca’s advisor, caution about integration risks and “potential overhang” on Mediobanca’s stock, downgrading it to “Hold.” Meanwhile, Lovaglio’s plan to appoint a new Mediobanca CEO post-OPAS—potentially sidelining Nagel—has sparked heated debate about leadership transitions.
The Road Ahead: Consolidation or Contention?
With the OPAS closing at 62.3%, MPS has secured significant control but faces hurdles to fully integrate Mediobanca. The reopening period could push it closer to the 66.67% goal, unlocking promised synergies and tax benefits. Lovaglio’s broader ambition—a super-pole with Banco BPM—hints at even grander plans, though regulatory and shareholder approval remains uncertain.
For now, MPS stands stronger, with a solid capital base and a dividend payout policy targeting 100% of earnings. Yet, Mediobanca’s defiance and market volatility suggest a contentious path forward. As Lovaglio scales Piazzetta Cuccia, the world watches whether MPS can truly redefine Italian banking—or if this conquest is just the start of a larger battle.
