Highly active in the mid-market private equity space, CMS‘s London team routinely handles transactions across various industries, including life sciences, professional services, technology, energy and infrastructure, and real estate. Practice head Jason Zemmel stands out for his ‘commercial acumen, sector knowledge and capabilities’, qualities which make him a key contact for some of the firm’s leading investor clients. Narinder Jugpal acts for a variety of sponsors and funds on leveraged buyouts, investment deals, and debt and equity restructurings – often with a cross-border focus. Daniel Weston and Jamie Burgess were promoted to partnership in May 2023; Weston is lauded for his ‘exceptional management capabilities in support of investor and management teams’, while Burgess is well regarded for his broad expertise across the full investment life cycle. Ben Booker acts on both sponsor and management-side buy and sell mandates, while Ben McParland is particularly recognised for his platform acquisition and bolt-on-focused practice.
