April 12, 2022

Dear

Cementos Argos SHAREHOLDERS' GENERAL ASSEMBLY

Subject: Proposals on item 4 of the agenda for the Shareholders' extraordinary meeting summoned for April 19, 2022

Dear Shareholders:

The administration presents the forthcoming proposals to the Cementos Argos Shareholders' General Assembly prior to the following considerations:

• 1. That it is the responsibility of the Board of Directors to deliberate and decide on the takeover bid for the common shares of Grupo de Inversiones Suramericana S.A. made by JGDB Holding S.A.S. on March 29, 2022 (hereinafter the "Offer");

• 2. That Dr. Jorge Mario Velasquez, Dr. Alejandro Piedrahíta and Dr. Rafael Olivella have mentioned a series of circumstances that give way to potential conflicts of interest to deliberate and decide, in their capacity as members of the Board of Directors, regarding the Offer, such and as stated in the communications of April 5, 2022 sent by them to the Chairman of Cementos Argos, which are attached to this proposal and that will be read during the Shareholders' General Assembly.

• 3. That the Shareholders' General Assembly is the competent body to hear about possible conflicts of interest of the members of the Board of Directors who have disclosed it; and

• 4. That without considering the three potentially conflicting members indicated above, the Board of Directors of Cementos Argos would have enough quorum to deliberate and decide on the Offer with the remaining members of the Board of Directors, who also hold the condition of independent members in accordance with the provisions of Law 964 of 2005.
