TORONTO and OKLAHOMA CITY, May 12, 2026 (GLOBE NEWSWIRE) -- Leading diversified professional services and investment management company, Colliers (NASDAQ, TSX: CIGI), today announced that the U.S. division of its Engineering segment has entered into a definitive agreement to partner with Frankfurt-Short-Bruza Associates P.C. (“FSB”). FSB will establish a national aviation practice for Colliers Engineering & Design (“Colliers Engineering”) and significantly expand capabilities in the federal, mission-critical and Native American sectors. Under Colliers' unique partnership model, FSB’s senior leadership team will become significant shareholders in Colliers Engineering and play a key role in its leadership going forward. Terms of the transaction were not disclosed. The transaction is expected to close in the second quarter of 2026.
