The European stockbroking business (which includes the Jersey office) is demerging from parent company Collins Stewart Tullett and the acquisition is dependent on the completion of the demerger.
Hawkpoint has offices in London and Paris and employs 120 staff.
The majority of equity is owned by the staff with 14% held by Mezzanine Management.
Clients include quoted and unquoted companies, private equity firms and entrepreneurs looking for advice on acquisitions, disposals, public offers and mergers, capital raisings and IPOs.
The firm also provides capital markets advice and has an established debt and restructuring advisory capability.
Collins Stewart says the acquisition is consistent with its strategy of creating a more broadly-based financial services group and is expected to enhance its client offering and growth potential and ability to service international clients.
