Cemex will proceed to make payment of the first installment of the cash dividend at the rate of approximately USD $0.000689 per share, against the delivery of coupon 151 (one hundred and fifty-one) adhered to the share certificates representing all of the outstanding shares that make up the paid-up capital stock of Cemex. CPO holders will receive approximately USD $0.002067 per CPO and ADS holders will receive approximately USD $0.020670 per ADS in the first installment of the cash dividend. Cemex intends to announce the corresponding final dividend amounts per share, CPO, and ADS for the first installment no later than June 14, 2024.

The first installment of the cash dividend should be paid to holders of bearer shares and CPO holders on June 18, 2024 in Mexican Pesos at the exchange rate determined by the Bank of Mexico (Banco de México) on June 14, 2024. ADS holders are expected to receive payment of the first installment of the dividend on or around June 26, 2024.
