Canadian investor Brookfield has joined the race for Uniti Group, teaming up with HRL Morrison on a joint ticket to take on a Macquarie-led group that this week lobbed a $5 per share bid for the infrastructure-focused telco.

Uniti signed a new exclusivity arrangement with the Brookfield/Morrison & Co consortium with a $5 million break-fee, but their offer of $4.50 per share is still under that of Macquarie Asset Management and PSP Investment.
