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.

Founded in 1945, FSB is an Oklahoma City-based multidisciplinary engineering and design firm with over 140 professionals across five offices, providing MEP engineering, structural engineering and architectural services. The firm has earned a national reputation as a leader in aviation facility design, backed by a portfolio of over $4.7 billion in federal and commercial aircraft hangar projects.

This transaction provides Colliers Engineering with immediate access to the high-barrier-to-entry aviation market, where FSB's best-in-class qualifications and longstanding client relationships are critical to success. FSB's focus on mission-critical markets also provides a significant opportunity for Colliers Engineering to capitalize on historic demand for data center projects.
