**Acquisition strengthens Harrison Street's European platform and expands credit, student housing and hospitality capabilities**

CHICAGO and TORONTO and GENEVA and LONDON, July 30, 2025 (GLOBE NEWSWIRE) -- Harrison Street Asset Management ("Harrison Street") the investment management division of Colliers (NASDAQ, TSX: CIGI), today announced the acquisition of a majority stake in RoundShield Partners ("RoundShield"), a leading European credit investment manager with $5.4 billion in assets under management.
