Lovaglio Wins Dramatic Shareholder Showdown: MPS Set for €16 Billion Mediobanca Merger

The Italy-based Banca Monte dei Paschi di Siena (MPS) has reinstated Luigi Lovaglio as its chief executive after a dramatic shareholder rebellion overturned the outgoing board's attempt to oust the architect of the bank's turnaround. The vote, held on April 15, 2026, handed Lovaglio's slate a commanding 49.95% of votes cast, decisively defeating the board-backed list that secured just 38.8%. The result clears the path for MPS to complete its planned merger with Mediobanca, an operation promising €16 billion in dividends over five years and potentially reshaping Italy's banking landscape.

Why This Matters

• Merger momentum restored: The vote removes the chief obstacle to MPS absorbing Mediobanca by year-end, creating a combined entity with major retail and investment banking reach across Italy.

• Shareholder dividends locked in: Lovaglio's industrial plan projects €16 billion in payouts through 2031, a windfall for MPS investors who saw the bank teeter on the brink just years ago.

• Board power struggle resolved: The new 15-member board will meet next week to formally assign powers and elect a chairman, ending weeks of boardroom paralysis.

• Legal cloud persists: Lovaglio, along with key shareholders Francesco Gaetano Caltagirone and Delfin's Francesco Milleri, remain under investigation by Milan prosecutors for alleged market manipulation during the Mediobanca takeover.

How the Vote Split Italy's Banking Elite

Approximately 65% of MPS share capital was represented at the Siena assembly, an unusually high turnout reflecting the bitter contest. The winning slate, presented by Plt Holding of the Tortora family, began with just 1.2% of the capital but swelled to nearly 50% as major institutional players broke ranks with the outgoing board.

The decisive swing came from Delfin, the holding company of the Del Vecchio family and MPS's largest shareholder with a 17.5% stake. Delfin's backing delivered roughly 32.5% of total capital to Lovaglio's camp, shattering a longstanding alliance with Caltagirone Group, which controls 13.5% and anchored the board's alternative list. Also pivotal was Banco BPM (3.7%), which distributes the Anima funds through MPS's network and has fueled speculation about a potential "third pole" banking partnership. International funds including Norges Bank and BlackRock added further heft.

The board's list, fronted by former Italy Treasury executive Fabrizio Palermo as the preferred CEO candidate, attracted about 25% of capital. Proxy advisors ISS and Glass Lewis had recommended this slate, drawing support from Vanguard and domestic pension funds (1.5%). A third minority list from Assogestioni, an association of Italian fund managers, captured 6.95% and secured one board seat.

The result produces a divided 15-member board: eight directors from Lovaglio's slate, six from the board's list, and one from Assogestioni. Despite the fractious campaign, Lovaglio dismissed any notion of revenge, describing the incoming board as "highly qualified" and expressing confidence in collaborative work. Among his allies joining the board are Cesare Bisoni, the candidate for chairman, and directors Flavia Mazzarella, Livia Amidani Aliberti, Massimo Di Carlo, Patrizia Albano, Carlo Corradini, and Paola Leoni Borali. The board list's representatives include outgoing chairman Nicola Maione, Palermo, veteran banker Corrado Passera, Carlo Vivaldi, Paolo Boccardelli, and Antonella Centra. Paola De Martini returns via the Assogestioni slate.

A Twelve-Month Drama from Takeover to Triumph

The assembly capped a year of corporate theatre that began in July 2025 when MPS launched a share-exchange offer for Mediobanca, the storied Milan investment bank known as "Piazzetta Cuccia." Lovaglio's audacious gambit—a provincial lender attempting to swallow an elite merchant bank—stunned Italy's financial establishment.

Phase One: The Takeover (July-September 2025). By early September 2025, MPS had crossed the 35% threshold and claimed first-shareholder status in Mediobanca. The offer closed on September 8 with a stunning 62.3% acceptance rate, thanks in part to a sweetened cash component added in late summer. On October 28, Mediobanca's shareholders elected a new board led by chairman Vittorio Grilli and CEO Alessandro Melzi d'Eril, replacing the outgoing leadership of Renato Pagliaro and Alberto Nagel.

Phase Two: Investigation Opens (November 2025). The celebratory mood soured in late November when news broke that Milan prosecutors had opened an investigation into Lovaglio, Caltagirone, and Milleri for alleged aggiotaggio (a form of market manipulation under Italian law involving artificially inflating securities prices or spreading false information) and obstruction of regulatory oversight. Investigators suspect an undisclosed pact among the trio to gain joint control of Mediobanca without triggering mandatory takeover obligations once their combined holdings exceeded 25%, potentially violating disclosure rules enforced by Consob, the European Central Bank (ECB), and IVASS, Italy's insurance regulator.

Phase Three: Merger Approval and Board Clash (March 2026). On March 10, 2026, the boards of MPS and Mediobanca approved a detailed merger blueprint calling for Mediobanca's incorporation into MPS and delisting by year-end. Lovaglio unveiled an industrial plan on February 27 projecting robust synergies from combining Mediobanca's corporate, investment, and high-end private banking units with MPS's retail footprint.

But on March 4, MPS's nominating committee stunned observers by excluding Lovaglio from the board's slate and naming Palermo, Vivaldi, and Passera as alternative CEO candidates. The Tortora family responded within weeks, sponsoring a rival slate that reinstated Lovaglio at its head. On March 24, the board formally endorsed Palermo as its sole CEO pick. The next day, the board stripped Lovaglio of his management powers and suspended him as director general. On April 7, it went further, firing him for cause—a move that backfired spectacularly when shareholders rallied to his defense eight days later.

What This Means for Shareholders and Depositors

For MPS equity holders, Lovaglio's return solidifies the merger narrative and its promised dividend stream. The integration plan envisages issuing up to 272 million new MPS shares—a capital increase of roughly €1.6 billion—to be distributed to Mediobanca shareholders at an exchange ratio of 2.45 MPS shares per Mediobanca share. This ratio embeds a premium over Mediobanca's pre-bid trading price.

Once the merger closes, Mediobanca will vanish from the Borsa Italiana—meaning shares will no longer trade on public exchanges, making them harder to sell and typically requiring shareholders to either accept the merger terms or face potential squeeze-out provisions. Its corporate and investment banking and premier private banking operations will be ring-fenced in a wholly owned, unlisted subsidiary that retains the Mediobanca name and manages its 13% stake in Assicurazioni Generali, Italy's largest insurer. Retail digital bank Banca Widiba and the Premier wealth unit will be folded into the MPS network, with Widiba adopting a rebranded name incorporating the Mediobanca mark.

For Mediobanca minority shareholders, delisting brings liquidity risks. Some may face squeeze-out provisions compelling sale at a fixed price. However, those who tendered shares during the takeover have already locked in their exchange ratio.

MPS depositors and clients should see minimal disruption. The bank has repeatedly emphasized continuity of service during integration, and regulatory capital ratios remain comfortably above ECB minimums. Employees face reorganization, particularly in overlapping wealth management and advisory units, though management has pledged to preserve talent and leverage complementary strengths rather than pursue aggressive headcount cuts.

The Legal Shadow and Regulatory Scrutiny

The Milan prosecutor's office, led by deputy prosecutor Roberto Pellicano and magistrates Luca Gaglio and Giovanni Polizzi, continues to probe whether Lovaglio, Caltagirone, and Milleri coordinated their Mediobanca share purchases in violation of Italy's market abuse statutes. Alleged offenses include aggiotaggio—artificially inflating or manipulating securities prices—and obstructing supervisory authorities by withholding material information.

Under Italian criminal law, aggiotaggio can draw prison terms of one to six years and fines reaching €3 million, with potential increases tied to illicit gains. Obstruction of regulatory oversight carries separate penalties. The investigation also encompasses Delfin, Caltagirone Group, and MPS itself as corporate entities under Legislative Decree 231/2001, Italy's corporate criminal liability framework, which holds companies administratively liable for crimes committed by executives or employees in the firm's interest. Sanctions can include substantial financial penalties and operational restrictions, such as bans on public contracts.

Consob, which initially found no evidence of a concerted action in a September 2025 report, has since received investigative files from prosecutors and is cooperating. Administrative fines for market abuse may run parallel to any criminal proceedings. All parties under investigation have declared full cooperation and expressed confidence in the lawfulness of their conduct.

Despite the legal uncertainty, markets greeted Lovaglio's victory enthusiastically. MPS shares surged on April 15 following the announcement of results, and continued to gain ground on April 16. Investors appear to bet that regulatory approvals will follow and that the merger will proceed on schedule.

The Next Steps

The reconstituted board convenes early next week to formalize leadership roles. Lovaglio is expected to regain executive powers immediately, while Cesare Bisoni is the leading candidate for chairman. The board must also designate two vice-chairmen and distribute committee assignments, a process that will test whether the rival factions can coexist productively.

Attention then shifts to securing final regulatory clearances from the ECB and Consob for the merger. Assuming no material obstacles arise, the integration timetable aims for completion by December 2026, with Mediobanca shareholders receiving new MPS stock and the combined entity beginning operations as Italy's third-largest banking group by assets.

Lovaglio has downplayed any interest in revisiting MPS's 13% holding in Generali, acquired via Mediobanca's portfolio. He termed the stake a "nice to have" but insisted the focus remains squarely on core banking synergies. That stance may reassure some investors wary of diversionary battles over insurance governance, though the Generali position remains a strategic wildcard.

Small Shareholders Cheer, Employees Applaud

The shareholder meeting itself unfolded as part corporate ritual, part public drama. Retail investors crowded the assembly hall in Siena, many voicing disbelief that the board would attempt to remove the executive who had rescued MPS from near-collapse and engineered its audacious conquest of a storied rival. When results were announced, applause erupted and chants of "Lovaglio, Lovaglio" echoed through the chamber. Staff lined the exits to greet the reinstated CEO with standing ovations.

Fondazione MPS, the historic charitable foundation tied to the bank, abstained from the governance vote, a gesture widely interpreted as unease with the board's handling of Lovaglio's ouster. The foundation, long a custodian of the bank's civic identity, has in recent years ceded direct influence as the Italy Treasury and private investors took control, but its symbolic weight remains considerable in a city where MPS has anchored the economy for centuries.

Broader Implications for Italy's Banking Sector

Lovaglio's survival and the impending MPS-Mediobanca merger represent more than a personal comeback. They signal a realignment of power among Italy's financial dynasties and institutional investors, with Delfin's break from Caltagirone marking a potential inflection point. Banco BPM's overt support for Lovaglio has fueled persistent speculation about a three-way combination—MPS, Mediobanca, and BPM—that could challenge the dominance of Intesa Sanpaolo and UniCredit.

For now, Lovaglio insists his focus is execution: delivering the synergies, dividends, and market credibility he promised. Whether he can navigate the legal inquiries, board tensions, and operational complexities of a transformative merger will determine whether yesterday's drama becomes tomorrow's success story or cautionary tale.
