Listed law firm Rosenblatt has acquired Manchester-based corporate finance boutique Convex Capital, as it attempts to diversify from law to the broader professional services sector.

Rosenblatt is buying Convex, which generated £8 million in revenues last year, for £22 million. The firm said in a statement that the acquisition is expected to help generate a regular flow of fee-based work for Rosenblatt’s corporate practice, which is focused on commercial transactions.
