In late October 2024, the company acquired its affiliated UK investment manager, Gabelli Securities International UK Limited (GSIL UK), for approximately $1 million through the issuance of new ordinary shares at a premium to net asset value, enabling self-management, broader service offerings to affiliated and third parties, and an increase in cash and investments. Earlier in February 2024, it completed an on-market repurchase tender, acquiring 19,500 ordinary shares to enhance shareholder value. The company changed its name to Gabelli Merchant Partners PLC on 2 April 2025, reflecting an evolution in its merchant banking-oriented operations while maintaining its core investment trust activities under SIC code 64301.
