CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX), announced today that it had entered into a series of private exchange agreements with certain institutional investors providing for such investors to exchange approximately U.S.$626 million aggregate principal amount of 3.25% Convertible Subordinated Notes due 2016 (CUSIP: 151290AZ6, P2253THV4 and 151290BB8; ISIN: US151290AZ66, USP2253THV46 and US151290BB89) issued by CEMEX (the “Existing Notes”) and held by such investors for (i) U.S.$321 million aggregate principal amount of new 3.72% Convertible Subordinated Notes due 2020 (the “Exchange Notes”) to be issued by CEMEX and (ii) an estimated 42 million American Depositary Shares of CEMEX (the “ADSs”).

The Exchange Notes will be convertible into ADSs based on an initial conversion rate of 84.0044 ADSs per U.S.$1,000 principal amount of Exchange Notes, which is equivalent to an initial conversion price of approximately U.S.$11.9041 per ADS. The conversion rate and the conversion price will be subject to adjustment in certain events, such as distributions of dividends or stock splits, in accordance with the terms of the Exchange Notes. The Exchange Notes are expected to bear CUSIP number 151290BT9 and ISIN US151290BT97.

The closing of each of these exchange transactions is subject to customary closing conditions. The Exchange Notes are expected to be issued on or around May 28, 2015 and the final settlement date for the exchange transactions is expected to be on or around June 8, 2015.
