It should also be noted that to many of the companies on its books, Panmure is joint broker rather than acting alone. This makes it far easier for clients to defect. And changes of ownership, with their knock-on unsettling effect on senior staff, have a nasty habit of precipitating such shakeouts. Clearly, Lazard has its own top-notch clients and it will be hoping Panmure will be able to move in and build a corporate broking service for them.
