The acquisition is expected to support the growth of Marex’s UK cash equities business, as well as expanding its services to UK institutional clients through offering a broader range of products, in particular among the asset and wealth management sectors. 

Specifically, the firm has said that the move aligns with Marex’s drive to expand its client base and bring new capabilities onto its platform.  

The close date for the deal is predicted for early 2026, subject to regulatory approval. 

“This acquisition gives us an opportunity to transform our existing equity market making business into a leading franchise, utilising the technology and connectivity of what is the leading brand in this market,” said Ian Lowitt, chief executive of Marex Group.  

“This deal is consistent with our strict financial criteria, and we see opportunities to materially improve its profitability. We believe we can gain economies from operating at scale and also benefit from Winterflood’s great technology and strong client relationships, which will enable us to introduce additional products and services from across our platform to a new set of clients.” 

Winterflood’s current offering provides execution services to more than 400 institutional clients, and also operates Winterflood Business Services Division, which covers outsourced dealing, settlement and custody services.

Bradley Dyer, chief executive of Winterflood Securities said: “We’re delighted to become part of Marex, which is a high-growth, global financial services company with a strong balance sheet. Our clients will continue to be served by the same team, while also benefitting from the backing of a large and growing company as well as access to a broader range of products and services from Marex.” 

The move follows recent developments and product expansions for Marex in recent months. In June 2025, the firm, alongside NatWest, unveiled a cooperative margin offsetting agreement, allowing clients who access FX futures through Marex, and FX prime brokerage services through NatWest’s markets business to receive margin relief.
