This proposal is required by applicable laws in Mexico and is standard for companies in Mexico at ordinary general shareholders meetings.

The documents described in item I of the agenda of the Ordinary Meeting are expected to be made available on Cemex’s website (www.cemex.com) by no later than February 21, 2025.

What is being proposed under item II of the agenda for the Ordinary Meeting?

The approval of a proposal for the allocation of profits for the fiscal year ended December 31, 2024, which includes the declaration of a cash dividend. The aggregate amount of the dividend is expected to be declared is USD 130 million, which shall be declared in U.S. dollars and is expected to be paid in four installments (the first installment on June 18, 2025, the second installment on September 18, 2025, the third installment on December 16, 2025 and the fourth installment on March 12, 2026). Shareholders holding physical certificates and holders of Cemex’s Ordinary Participation Certificates (“CPOs”) would receive the dividend payment in Mexican pesos, while holders of Cemex’s American Depositary Shares (ADS) would receive the dividend payment in U.S. dollars.

What is being proposed under item III of the agenda for the Ordinary Meeting?

Similar to what was discussed and approved in Cemex’s Ordinary General Shareholders Meeting held in 2024, this item includes the discussion and approval to set the amount of a fund that would be used for the repurchase of Cemex’s shares or other instruments representing such shares. The share buyback program being proposed would be of up to U.S. $500 million or its equivalent in Mexican Pesos for the remainder of 2025, starting on March 25, 2025, and continuing until the next Cemex Ordinary Shareholders Meeting, which is expected to be held no later than April 30, 2026.

In general, the procedures and approvals implemented for the repurchase of Cemex’s shares in previous years, and which were in effect during 2024, will continue to be implemented until the date of the next Cemex Ordinary General Shareholders Meeting. In particular, if the proposal is approved, share repurchases under the share buyback program will be made from time to time at prices and in accordance with procedures permitted by applicable laws, as determined by the Chairman of Cemex’s Board of Directors, the CEO of Cemex, or the Executive Vice President of Finance and Administration of Cemex. This share buyback program does not obligate Cemex to acquire a specific number of shares, nor does it imply that any repurchases will be carried out. The timing, frequency, and amount of the repurchase activity will depend on various factors such as cash flow levels from operations, cash needs for investment in Cemex’s businesses, Cemex’s stock price, market conditions, and other factors, such as contractual, if any such restrictions were to exist. The share buyback program may not be implemented, suspended, modified, or discontinued at any time.
