Marex to Acquire Winterflood Securities for £103.9 Million in Strategic Expansion

Marex Group plc has announced its intention to acquire Winterflood Securities from Close Brothers Group plc for approximately £103.9 million in cash, including a £15 million premium. The deal, which is subject to regulatory approval, is expected to close in early 2026.

Winterflood, a significant player in the UK equity trading space with roughly 15% market share on the London Stock Exchange, serves over 400 institutional clients. Its proprietary trading technology and business services platform are key assets Marex plans to integrate.

Marex CEO Ian Lowitt said the acquisition fits into the firm's broader strategy of expanding in UK cash equities and diversifying revenue streams. "We believe we can gain economies from operating at scale and also benefit from Winterflood's great technology and strong client relationships," he commented.

This move follows Marex's recent activity in the FX and commodities markets, including its planned acquisition of Brazilian agricultural firm Agrinvest Commodities and a cross-margining partnership with NatWest aimed at optimizing collateral management for FX clients.
