Marex Spectron Group Ltd, which last week said it was considering a flotation has confirmed it will list on London’s main market.
The initial public offering (IPO) will see some existing shareholders of the commodities broker sell their shares.
The offer price has yet to be set but will be determined following a book-building process, with the firm’s advisors targeting institutional investors outside of the US.
The listing is expected to take place in mid-June.
Marex describes itself as “an essential global liquidity hub”; it connects its clients to energy, commodity and financial markets and provides market-making, price discovery and data services.
