US and UK securities expert Claire Keast-Butler heads up the team at Cooley (UK) LLP following the April 2024 departure of David Boles and is particularly well-versed in handling IPOs, public M&A, and dual listings for UK clients. The practice maintains close relationships with a host of clients in the life sciences sector, who routinely instruct it to act on primary and follow-on fundraises with both debt and equity elements. Simon Amies, who joined the team from Covington & Burling LLP in May 2023, is a key contact for this line of work.
