Grupo Argos proposes a distribution of USD 230 million to all Cementos Argos shareholders through a share repurchase

• Grupo Argos has requested that the management of Cementos Argos call an Extraordinary Shareholders’ Meeting to propose a distribution of USD 230 million from the proceeds obtained by the company following the divestment in Summit Materials in February 2025.
• The proposal to be submitted for the consideration of the Shareholders’ Meeting consists of carrying out the distribution through an additional and independent share repurchase program, separate from Cementos Argos’ current program. This mechanism is an efficient and widely used way to distribute value, while also having a positive effect on the stock’s liquidity.
• If approved by the Cementos Argos Shareholders’ Meeting, the repurchase will be executed through the independent mechanism regulated by the Colombian Stock Exchange, at a price of COP 13,659 per share.

Grupo Argos, in its capacity as a shareholder of Cementos Argos, requested that the company call an Extraordinary Shareholders’ Meeting to propose a distribution of USD 230 million from the proceeds obtained from the divestment in Summit Materials in February 2025. This distribution would be carried out through a share repurchase offer for all Cementos Argos shareholders.

This repurchase offer would be additional and independent from the current share buyback program being executed by Cementos Argos. It is a simple, efficient, and equitable mechanism that allows shareholders to receive the funds more quickly, as the intention is to complete the process before the end of the current year.

The sale of Summit Materials to Quikrete represented a cash value of approximately USD 2.875 billion for Cementos Argos, in addition to the value generated in 2024 by the combination of Argos USA’s assets with Summit Materials. In total, Cementos Argos received approximately USD 4.071 billion from these two transactions —the merger with Summit Materials and the subsequent sale to Quikrete—, of which this proposed distribution would represent 5.65%.

The offer would be carried out through the independent mechanism regulated by the Colombian Stock Exchange. The proposed price is COP 13,659 per share. This price was determined based on the midpoint of the valuation range estimated by Inverlink S.A.S. for Cementos Argos’ operating business in the Spin-off Project approved by the Cementos Argos Shareholders’ Meeting on March 25, 2025, and the company’s outstanding shares as of yesterday.

With this proposal, Grupo Argos reaffirms its commitment to the creation and transfer of value for all Cementos Argos shareholders.
