The market regulator Consob (Italian National Commission for Companies and the Stock Exchange) has documented a historic exodus from Piazza Affari, with 30 companies abandoning the Milan stock exchange during 2025, stripping approximately €2.5 billion in market capitalization from the Italian bourse. The revelation, delivered by Consob Acting President Chiara Mosca in the agency's 2026 annual report, underscores a deepening structural challenge for Italy's capital markets—even as overall valuations climbed to record highs.
Why This Matters
• Historic low: The main market, Euronext Milan, now lists a record-low 198 companies, down from 209 at the end of 2024.
• Takeover wave: 9 out of 11 delisting operations on the regulated market were triggered by public buyout offers (OPA/OPAS) — the Italian legal terms for public acquisition offers (Offerta Pubblica di Acquisto) and acquisition-with-exchange offers (Offerta Pubblica di Acquisto e Scambio) — accounting for €1.75 billion in lost capitalization.
• Investor squeeze: Fewer listed firms means reduced investment choice for retail savers and pension funds, while the market's representation of Italy's real economy continues to shrink.
The Diverging Forces Reshaping Italy's Exchange
Between 2010 and 2025, Piazza Affari evolved along two contradictory paths. On one hand, stock price appreciation lifted total capitalization by roughly €750 billion. On the other, the relentless tide of departures vastly exceeded new arrivals: €187 billion in capitalization vanished due to delisting, while fresh initial public offerings (IPOs) contributed a mere €91 billion, resulting in a net loss of €96 billion over the 15-year span.
The trend accelerated sharply in the past five years, during which the negative balance ballooned to €69 billion. Mosca highlighted a particularly troubling detail: zero new entrants joined the regulated segment during 2025, a first in modern Italian market history. Instead, the smaller Euronext Growth Milan segment absorbed 11 delisting operations that erased an additional €570 million in capitalization.
By June 2026, Piazza Affari's total market cap had swelled to €1.209 trillion, up from €1.077 trillion at year-end 2025. Yet that headline figure masks a hollowing-out effect. The gains are confined to a shrinking roster of large-cap survivors—chiefly utilities, banks, and luxury conglomerates—whose share-price rallies have disguised the attrition of mid-sized and smaller companies.
Who Left and Why
The 2025 departures encompassed household names and niche players alike. Unieuro, the consumer-electronics retailer, exited after a buyout. Intermonte Partners SIM and Mittel, both financial-services firms, opted for private status. In early 2026, Telecom Italia (TIM) completed the conversion of its savings shares into ordinary stock, effectively delisting one share class, while additional high-profile exits—Mediobanca and Recordati—loom on the calendar.
Analysts point to a confluence of drivers. Public buyout offers remain the most direct cause: private-equity funds and strategic acquirers have found bargains in undervalued Italian mid-caps, offering premiums that boards and minority shareholders find difficult to refuse. Once control shifts, delisting follows almost automatically.
Beyond M&A, many companies cite chronic undervaluation and poor liquidity. Shares of smaller firms often trade sporadically, frustrating management and deterring institutional investors who prioritize daily turnover. For executives, maintaining a public listing entails steep compliance costs—audits, disclosure obligations, investor-relations teams—without the compensating benefit of liquid, fairly priced equity. Private status, by contrast, delivers managerial flexibility and shields companies from quarterly earnings pressures.
A third factor is the gravitational pull of foreign exchanges and alternative capital. Some Italian champions have migrated to New York or London, seeking deeper pools of liquidity and analyst coverage. Others have bypassed public markets entirely, raising growth capital from private-equity and debt funds that promise tailored terms and patient capital.
What This Means for Residents and Savers
For the roughly 6 million Italians who hold shares directly or through mutual funds and pension plans, the shrinking menu of listed stocks poses tangible risks. Fewer companies mean less sector diversification: if you want exposure to mid-sized manufacturing, technology start-ups, or regional service providers, Piazza Affari no longer offers much choice. Concentration rises, and with it the potential for portfolio volatility.
Retail investors who owned shares in companies taken private often fare reasonably well during the buyout itself—OPA prices typically carry a 20–30% premium to pre-announcement trading levels. But once the deal closes, those investors must redeploy proceeds into a narrower field or migrate to foreign equities, incurring currency risk and higher transaction fees.
The impact extends to the real economy. Small and medium-sized enterprises (SMEs), the backbone of Italy's industrial districts, face diminished access to equity finance. With the IPO window effectively shut—no new regulated-market listings in 2025—growth-stage firms must lean harder on bank credit or negotiate with private funds, both of which come with tighter covenants and higher costs of capital. Over time, that financing gap can constrain expansion, innovation, and hiring.
Italy's market capitalization now represents only 51% of GDP, well below the European Union average of 75% and dwarfed by the United States' 247%. This disparity means Italians have fewer opportunities to participate in equity wealth creation through their domestic market compared to residents of other developed economies—a significant disadvantage when building long-term savings and retirement portfolios. A shallow equity market limits the economy's ability to channel household savings into productive investment, reinforcing reliance on low-yielding bank deposits and government bonds.
A Broader European Malaise
Italy is not alone. Between 2010 and 2022, the number of publicly traded companies across the European Union fell by roughly 15%. In 2023, the pan-European Euronext platform recorded 110 delistings—nearly triple the prior year's tally—shedding €467 billion in aggregate market value. Paris led the EU in delisting value during 2025 (€404 billion), while Milan topped the league table for transaction volume (24 deals). Across the Channel, the London Stock Exchange saw 88 exits in 2024 alone, more than double the 2023 figure.
European policymakers have begun to respond. The European Commission is pushing for harmonized delisting rules that would mandate shareholder votes, minimum quorum thresholds, and fair exit prices for minority investors. Proposals under the Capital Markets Union (CMU) and Savings and Investments Union (SIU) frameworks include tax incentives for retail equity investment, support for institutional fund managers based in the EU, and even the consolidation of national exchanges to create pan-European liquidity hubs.
Italy and Germany already impose stricter protections than most member states. Under Italian law, minority shareholders in a delisting scenario enjoy withdrawal rights or the guarantee of a mandatory buyout offer at a fair valuation. That regulatory rigor offers a measure of comfort but has not stemmed the outflow.
Risks on the Horizon
Consob's 2026 report sounded additional alarms beyond the delisting wave. Acting President Mosca flagged the rise of "gamblification"—the gamification of retail investing amplified by artificial intelligence and so-called prediction markets. These platforms, which blend speculative trading with game-like interfaces, can lure inexperienced savers into high-risk bets, magnifying potential losses during market downturns.
The regulator also noted the growing role of activist investors and private-equity sponsors in driving takeovers. While buyouts can unlock value for selling shareholders, they also reduce transparency: once a company goes private, detailed financial reporting ceases, and the broader public loses visibility into corporate performance and governance.
The Path Forward
Reversing the delisting tide will require action on multiple fronts. Making IPOs more attractive is a necessary first step: streamlining prospectus requirements, lowering listing fees, and fostering a culture that celebrates public ownership rather than viewing it as a compliance burden. Tax breaks for long-term equity holders—both retail and institutional—could deepen demand and improve liquidity for newly listed shares.
At the same time, Italy must address the valuation discount that has plagued its market for years. Structural reforms that boost productivity, reduce bureaucracy, and enhance corporate governance can lift investor confidence and narrow the gap between Italian and international peers. Greater collaboration among Consob, Borsa Italiana, and the Treasury to promote market education and transparency may also help rebuild trust.
For now, the paradox persists: Piazza Affari's headline capitalization reaches new peaks, buoyed by a handful of blue-chip giants, while the exchange steadily loses the breadth and diversity that once made it a mirror of Italy's entrepreneurial fabric. Whether 2026 marks an inflection point or merely another chapter in a long decline will hinge on whether policymakers, corporate leaders, and investors can forge a shared commitment to revitalizing Italy's public equity culture.
