European Regulators Tighten Rules on PE Ownership of Critical Infrastructure

The proposed European Critical Infrastructure Protection Directive would establish mandatory screening for all acquisitions of "critical infrastructure assets" by financial sponsors, including PE funds, sovereign wealth funds, and hedge funds. The directive defines critical infrastructure broadly, encompassing energy networks, telecommunications, water systems, ports, airports, and data center operations.

What the Rules Would Require

• Mandatory pre-notification to national screening authorities for acquisitions above €100 million in designated sectors
• A 90-day review period, extendable by 60 days for complex transactions
• Minimum ownership retention requirements (the fund must hold the asset for at least 7 years)
• Restrictions on leverage above 50% of enterprise value for critical infrastructure assets
• Annual reporting requirements on operational investment and maintenance capex

Industry Concerns

Infrastructure investment associations have pushed back sharply on the leverage restrictions and minimum holding periods. Invest Europe, the continent's PE trade body, warned that the proposals could reduce infrastructure investment by 25-30%, worsening the estimated €1.5 trillion European infrastructure funding gap.

The directive was partly motivated by controversies surrounding PE-owned water companies in the UK and energy distribution networks in Southern Europe, where critics argued that leveraged buyout structures had underinvested in maintenance while extracting dividends. Several member states, including France and Germany, have expressed support for the initiative.

The European Parliament will debate the directive in Q2 2026, with implementation expected no earlier than 2028. In the interim, several national governments are implementing their own screening mechanisms, creating a patchwork of regulations that complicates cross-border transactions.
