EXTRAORDINARY GENERAL SHAREHOLDERS’ MEETING NOTICE

The Board of Directors of Bancolombia S.A. hereby calls the shareholders to an Extraordinary General Shareholders' Meeting, which will be held in person on August 27, 2025, at 10:00 a.m., at the Bank’s Headquarters located at Carrera 48 Number 26-85, Torre Sur, 11th Floor, in the city of Medellín.

The proposed agenda for the meeting is as follows:

1.Verification of quorum

2.Reading of the agenda

3.Election of commission for vote count, approval, and execution of the minutes

4.Cancellation of the registration of Bancolombia S.A. shares in the National Registry of Securities and Issuers (RNVE) and in the Colombian Stock Exchange (BVC)

5.Proposal to Amend the Corporate Bylaws

If item four on the agenda is not unanimously approved by all outstanding shares of the company, the shareholders who vote in favor of it will be required to initiate a public tender offer for the shares owned by absent or dissenting shareholders of said meeting.

We want to remind investors that, in line with the evolution of the corporate structure under which Grupo Cibest S.A. (hereinafter “Grupo Cibest”) was created as the parent company of the group’s businesses, Bancolombia shareholders became shareholders of Grupo Cibest, maintaining the same number of shares and ownership percentage under the same terms and conditions as they had in Bancolombia. As a result of this evolution, Bancolombia’s current shareholders are five companies, namely Grupo Cibest S.A. and four of its subsidiaries, to whom this notice is addressed.

Shareholders may be represented at the Meeting by granting powers of attorney in writing to authorized representatives, in accordance with Colombian law. Powers of attorney may not be granted to employees of the Bank nor to any other person directly or indirectly related to the management of Bancolombia.
