CIGI Colliers International Group Inc

Colliers (NASDAQ and TSX: CIGI) has been named to the IAOP’s 2025 Global Outsourcing 100® list. This is the 19th consecutive year that Colliers has been recognized as one of the world's best outsourcing service providers.

Colliers provides an integrated suite of solutions across the entire lifecycle of an asset, including transactional services, property management, valuation and advisory and loan servicing. Colliers’ professionals partner with clients across industries and geographies to enhance the performance of their real estate portfolios and people.

“The fast pace and complexity of change – from access to AI-driven insights and regulatory updates to evolving workforce expectations and the demand for smarter, more adaptive spaces – are driving organizations to rethink how they use their corporate real estate and manage their portfolios strategically. Our continued recognition by IAOP reflects our deep expertise, tenacity and enterprising mindset in helping clients maximize the potential of their workplaces,” said Chris McLernon, CEO of Real Estate Services | Global at Colliers.

The 2025 Global Outsourcing 100® is based on a rigorous scoring methodology that includes a review by an independent panel of IAOP customer members with extensive experience in selecting outsourcing service providers and advisors for their organizations.

“Congratulations to the exceptional companies recognized in the 2025 Global Outsourcing 100® for their steadfast commitment to excellence and innovation during a year of both opportunity and complexity.
