CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX) announced today the exercise of U.S. $200 million of Note Purchase Contracts underlying the Contingent Convertible Units issued by CEMEX on October 3, 2014 (the “Contingent Convertible Units”). As a result of the exercise, CEMEX will issue U.S.$200 million in aggregate principal amount of Convertible Subordinated Notes due 2020 (the “New Convertible Notes”) on March 13, 2015 to the holders of the Contingent Convertible Units in respect of which Note Purchase Contracts have been exercised, in exchange for a cash payment of U.S.$200 million.

The proceeds of the issuance of the New Convertible Notes will be used to finance, in part, the payment at maturity of CEMEX’s 4.875% Convertible Subordinated Notes due 2015 (the “2015 Existing Convertible Notes”).

Interest on the New Convertible Notes will be payable at a rate equal to 1.770% (the 5-year swap rate on March 11, 2015) plus a spread of 195 basis points, subject to incremental adjustments if the 5 Day Average VWAP (as defined below) of CEMEX’s American Depositary Shares (the “ADSs”) is lower than U.S.$8.62. Interest on the New Convertible Notes will be payable semi-annually in arrears on March 15 and September 15 of each year, commencing on September 15, 2015. The New Convertible Notes will be convertible by holders into ADSs at an initial conversion price equal to the greater of (a) U.S.$11.20, (b) 130% of the 5 Day Average VWAP of the ADSs and (c) 110% of the closing sale price of the ADSs on the New York Stock Exchange on March 13, 2015. The “5 Day Average VWAP” of the ADSs will be equal to the average of the daily volume-weighted average prices of the ADSs for the 5 trading day period beginning on March 18, 2015. The initial conversion rate of the New Convertible Notes will be equal to the quotient of (x) 1,000 divided by (y) the initial conversion price, rounded to the nearest 1/10,000th of an ADS. CEMEX’s ordinary shares currently held in treasury that underlie the 2015 Existing Convertible Notes will be kept in CEMEX’s treasury and will be re-allocated to ensure the conversion rights of the New Convertible Notes that are issued.
