Robey Warshaw LLP is an elite, independent corporate finance advisory firm based in London. Founded in 2013 by Sir Simon Robey, Simon Warshaw, and Philip Apostolides, the firm specializes in providing high-level strategic and financial advice to major domestic and international corporations, often on complex mergers and acquisitions, demergers, and other significant corporate transactions. Known for its discretion, senior-level involvement, and success in high-profile deals, Robey Warshaw has established itself as a go-to adviser for FTSE 100 companies and global entities.
The London headquarters is the sole global office, serving as the central hub for all client advisory services, deal origination, execution, and firm operations.
Located in a prestigious Grade II listed building in the historic St James's district, known for its distinguished architecture and proximity to key financial and business centers.
Characterized by intense intellectual challenge, a high degree of partner involvement, discretion, and a collaborative, results-driven environment focused on bespoke client solutions.
As the command center for one of the world's most influential boutique M&A advisory firms, it's where strategies for landmark multi-billion pound global transactions are developed and executed.
While headquartered solely in London, Robey Warshaw possesses a significant global presence through its advisory work. The firm counsels a diverse international clientele, including multinational corporations, sovereign wealth funds, and major private equity firms, on complex cross-border mergers, acquisitions, and strategic financial matters. Their global reach is facilitated by the extensive experience and networks of its senior partners rather than a physical network of international offices, allowing them to provide bespoke advice on transactions worldwide.
