Italy's CDP Escalates Dispute with Euronext: Lawsuit Signals Growing Concerns Over Milan Stock Exchange Autonomy

RROME, March 18, 2026 - Italy's state-owned investment fund, Cassa Depositi e Prestiti (CDP), has officially launched legal action against Euronext, the pan-European exchange operator, marking a significant escalation in a long-simmering dispute over the governance of the Milan stock exchange, Borsa Italiana. The lawsuit, filed earlier this week, centers around CDP's concerns that Euronext's recent strategic shifts are eroding the autonomy and strategic importance of the Milan bourse within the broader European group.

Euronext acquired Borsa Italiana in 2021, creating one of Europe's leading exchange groups. The initial deal was presented as a means of bolstering competitiveness and fostering a more integrated European capital market. However, tensions have steadily mounted over the past several months as Euronext implemented plans to centralize certain trading activities and streamline governance structures. CDP, a major shareholder in Borsa Italiana, argues these moves disproportionately benefit Euronext's other European markets - Paris, Amsterdam, Brussels, Lisbon, Dublin and Oslo - at the expense of the Milan exchange.

Sources close to the matter indicate that the core of the disagreement lies in Euronext's perceived prioritization of group-wide efficiency over the specific needs and growth potential of the Italian market. CDP fears that the centralization of key functions, such as clearing and settlement, and trading technology, will diminish Milan's role as a vital hub for Italian businesses seeking capital and investment. The Italian government, which views Borsa Italiana as a strategically important asset, has strongly supported CDP's position and encouraged a firm stance against any actions perceived as detrimental to Italy's financial interests.

"This isn't simply about a corporate dispute; it's about protecting Italy's financial sovereignty," stated a senior government official, speaking on condition of anonymity. "We need to ensure that the Milan stock exchange continues to thrive and serve the needs of Italian companies, and that requires a level of autonomy that we believe is currently under threat."

The lawsuit specifically challenges Euronext's recent decisions regarding the location of key operational functions and the composition of Borsa Italiana's governing board. CDP alleges that these decisions were made without sufficient consultation and demonstrate a clear intention to exert undue control over the Milan exchange. They are seeking a judicial review of these actions and a guarantee of greater autonomy for Borsa Italiana in future decision-making.

The implications of this legal battle extend beyond the immediate governance of the Milan stock exchange. It raises broader questions about the balance of power within Euronext and the potential for conflicts of interest when a pan-European exchange operator manages multiple national markets. Other national shareholders within the Euronext group are reportedly watching the situation closely, concerned that a weakening of Borsa Italiana could set a precedent for similar disputes in the future.

Analysts predict that the lawsuit could lead to a protracted legal battle, potentially lasting several years. A negotiated settlement is possible, but appears increasingly unlikely given the firm positions adopted by both sides. Some experts suggest that CDP may be exploring options for increasing its stake in Borsa Italiana, or even seeking to regain full control of the exchange, although the financial implications of such a move would be substantial. The situation is further complicated by the evolving regulatory landscape in Europe, with increasing calls for greater national control over strategic assets. This legal action could also influence future mergers and acquisitions in the European exchange industry, prompting regulators to scrutinize deals more closely to ensure they do not compromise national interests. The outcome will be closely watched by financial institutions and investors across Europe, as it could reshape the landscape of the continent's capital markets.

The CDP is being represented by leading international law firm, Latham & Watkins, known for its expertise in complex financial litigation. Euronext has publicly stated its commitment to defending its position and maintaining the integrity of its pan-European strategy. The first court hearing is scheduled for late April.
