## Exhibit 99.1

**EXHIBIT 99.1**

**Colliers Announces Normal Course Issuer Bid**

TORONTO, May 13, 2026 (GLOBE NEWSWIRE) -- Colliers International Group Inc. (NASDAQ: CIGI) (TSX: CIGI) ("Colliers") announced today that the Toronto Stock Exchange (the "TSX") has accepted a notice of its intention to make a normal course issuer bid (the "NCIB") with respect to its outstanding subordinate voting shares (the "Subordinate Voting Shares").

The notice provides that Colliers may, during the twelve month period commencing May 15, 2026 and ending no later than May 14, 2027, purchase through the facilities of the TSX, alternative Canadian Trading Systems or The NASDAQ Stock Market ("Nasdaq") up to 4,300,000 Subordinate Voting Shares in total, being approximately 10% of the 43,850,289 shares comprising the "public float" as of May 12, 2026 of such class of shares. Purchases of Subordinate Voting Shares through Nasdaq will be made in the normal course and will not, during the twelve month period ending May 14, 2027 exceed, in the aggregate, 5% of the outstanding Subordinate Voting Shares as at the commencement of the NCIB. The price which Colliers will pay for any such shares will be the market price at the time of acquisition. During the period of this NCIB, Colliers may make purchases under the NCIB by means of open market transactions or otherwise as permitted by the Ontario Securities Commission, Canadian Securities Administrators and/or Nasdaq. The actual number of Subordinate Voting Shares which may be purchased pursuant to the NCIB and the timing of any such purchases will be determined by senior management. The average daily trading volume on the TSX from November 1, 2025 to April 30, 2026 was 88,313 Subordinate Voting Shares. Daily purchases under the NCIB will be limited to 22,078 Subordinate Voting Shares, other than block purchases. All shares purchased under the NCIB will be cancelled.

As of May 12, 2026, there were 49,778,127 Subordinate Voting Shares and 1,325,694 multiple voting shares outstanding.

Colliers may purchase its Subordinate Voting Shares, from time to time, if it believes that the market price of its Subordinate Voting Shares is attractive and that the purchase would be an appropriate use of corporate funds and in the best interests of Colliers.

Colliers' previous NCIB authorized the purchase of up to 4,300,000 Subordinate Voting Shares and expired on May 8, 2026. Colliers did not purchase any Subordinate Voting Shares pursuant to this previous NCIB.

BMO Nesbitt Burns Inc. ("BMO") has been appointed to act as Colliers' designated broker to make purchases of Subordinate Voting Shares pursuant to the NCIB. Colliers has also entered into an automatic share purchase plan ("ASPP") with BMO allowing it to purchase common shares under the NCIB when Colliers would ordinarily not be permitted to purchase shares due to regulatory restrictions and customary self-imposed black-out periods. Before entering a black-out period, Colliers may, but is not required to, instruct BMO to make purchases under the NCIB during such a period based on parameters set by Colliers in accordance with the ASPP, TSX rules and applicable securities laws. All purchases made under the ASPP are included in computing the number of Subordinate Voting Shares purchased under the NCIB. The ASPP has been pre-cleared by the TSX and will be implemented and effective May 15, 2026.
