Miami International Holdings Closes Acquisition of The International Stock Exchange

According to a story in The Trade news, Miami International Holdings’ (MIH) acquisition of The International Stock Exchange Group (TISE) – via its wholly owned subsidiary MIH East Holdings – has come into effect. The initial agreement on a recommended cash offer for MIH was reached in March 2025. The deal, valued at £70.4 million, will see MIH acquire the entire issued and to be issued ordinary share capital of TISE not already owned by MIH East Holdings. “MIH’s acquisition of TISE represents a key milestone in advancing our international growth strategy,” said Thomas Gallagher, chair and chief executive of MIH. “We are excited to establish a presence in Guernsey and believe that TISE’s strong reputation and solid business foundation provide MIH with significant opportunity to enhance our offerings and expand our international footprint through investments in TISE’s technology, business development and operational processes.” By the end of 2024, TISE, which is headquartered in Guernsey, had reported over 4,400 securities on its Official List, equating to a total market value of more than £750 billion.  The exchange has said that the acquisition will help to drive its overall growth and expand its current financial markets and securities services offerings.
