Grupo Argos received COP 493,000 million from the share buyback of Cementos Argos

• In September 2025, Grupo Argos asked the management of Cementos Argos to submit to its General Shareholders’ Meeting the proposal to distribute part of the profits obtained by the company following the divestment in Summit Materials in February 2025.
• The buyback recorded acceptances for more than 65.6 million shares, equivalent to 5% of the total outstanding shares of Cementos Argos.
• This transaction continues to provide liquidity to the Colombian securities market, while unlocking value for all Cementos Argos shareholders and generating funds that Grupo Argos will use to reduce its net debt.

Last Friday, November 7, the acceptance period for the repurchase of Cementos Argos shares came to an end. This process is part of the request made by Grupo Argos to submit to the Shareholders’ Meeting of the cement company the proposal to distribute part of the profits obtained after the divestment in Summit Materials.

The sale of the stake in Summit Materials represented for Cementos Argos a cash consideration of approximately USD 2.875 billion, in addition to the value generated in 2024 by the combination of Argos USA’s assets with this company. In total, for these two transactions – the combination with Summit Materials and the subsequent sale to Quickrete – Cementos Argos received approximately USD 4.1 billion.

The program was executed at a price of COP 13,659 per Cementos Argos share and included the participation of both institutional and individual shareholders, reflecting the market’s confidence in the long-term strategy of Cementos Argos and its parent company, Grupo Argos. The transaction reinforces Grupo Argos’ commitment to disciplined capital management, aimed at balancing financial strength with sustainable returns for investors.

Grupo Argos took part in the mechanism and received cash proceeds of COP 493,000 million, which it will allocate to reducing its net indebtedness, giving it greater financial flexibility to continue executing its strategy. This initiative is aligned with programs such as Sprint, at Cementos Argos, and EnergizarC, at Celsia, which have contributed to strengthening the share price performance of Grupo Argos’ listed companies, increasing their profitability, optimizing their capital structure and promoting value creation for shareholders through actions such as debt reduction, improved share liquidity and a focus on the construction materials and infrastructure businesses.
