The acquisition of SUSI Partners by UK-based specialist asset manager Gresham House, which was first announced in September 2025, has been completed.

The integration of SUSI Partners into Gresham House creates a €3.1 billion energy transition infrastructure platform, which ranks among Europe’s top 10 largest in this segment.[1]

Going forward, the unified Energy Transition division will be led by Marco van Daele, who previously served as CEO of SUSI Partners. SUSI Partners’ portfolio management leads and teams continue to manage the firm’s Equity, Credit, and Asia strategies while Gresham House’s UK-focused strategies continue to be managed by Gresham House personnel. The team will jointly focus on growing the combined Energy Transition division, offering clients a wider range of strategies and products, and leveraging both firms’ deep investment expertise.
