## Exhibit 99.1

**EXHIBIT 99.1**

**Colliers Completes C$550 Million Senior Notes Issuance**

**TORONTO, March 25, 2026 (GLOBE NEWSWIRE) --** Colliers International Group Inc. (NASDAQ and TSX: CIGI) ("Colliers" or the "Company") today announced the completion of a private placement of C$550 million, equivalent to approximately US$400 million, of 4.73% fixed rate senior unsecured notes due 2033 (the "Notes").

The Notes were issued by Colliers Macaulay Nicolls Inc., a subsidiary of Colliers, and are fully guaranteed by Colliers. The payment obligations under the Notes rank equally with all other unsecured and unsubordinated indebtedness of the issuer and Colliers, including Colliers' senior unsecured revolving credit facility and existing senior unsecured notes.

Colliers intends to use the proceeds for general corporate purposes, including the repayment of outstanding borrowings under its revolving credit facility.

"This financing further strengthens our balance sheet and enhances our financial flexibility as we continue to execute our long term growth strategy," said Michael Harding, Vice President Finance & Treasurer. "The strong support from both new and existing institutional investors reflects continued confidence in our performance and disciplined approach to capital management," he concluded.

**About the Notes**

The Notes offered in the private placement have not been and will not be registered under the U.S. Securities Act of 1933, as amended, or the securities laws of any other jurisdiction. The Notes may not be offered or sold in the United States absent registration with the U.S. Securities and Exchange Commission or pursuant to an applicable exemption from such registration requirements.

This press release does not constitute an offer to sell or a solicitation of an offer to buy the Notes, nor shall there be any sale of Notes in any jurisdiction in which such an offer, sale or solicitation would be unlawful.
