CEMEX, S.A.B. de C.V. (“CEMEX”) (NYSE: CX) announced today that the interest rate of its U.S.$200 million in aggregate principal amount of Convertible Subordinated Notes due 2020 (the “Convertible Notes”) is 3.720% and the initial conversion rate of the Convertible Notes is 80.7735 of CEMEX’s American Depositary Shares (the “ADSs”) per U.S.$1,000 principal amount of the Convertible Notes.

The interest rate applicable to the Convertible Notes of 3.720% was determined based on the 5-year swap rate on March 11, 2015 (1.770%), plus a spread of 195 basis points. Because the average of the daily volume-weighted average prices of the ADSs for the 5 trading day period beginning on March 18, 2015 (the “5 Day Average VWAP”) was U.S.$9.5233, which is higher than U.S.$8.62, no adjustment to the interest rate was required. Interest on the Convertible Notes will be payable semi-annually in arrears on March 15 and September 15 of each year, commencing on September 15, 2015.

The initial conversion price applicable to the Convertible Notes of U.S.$12.3803 was determined as the amount equal to the greater of (a) U.S.$11.20, (b) U.S.$12.3803, which is 130% of the 5 Day Average VWAP of the ADSs, and (c) U.S.$10.659, which is 110% of the closing sale price of the ADSs on the New York Stock Exchange on March 13, 2015. The initial conversion rate of the Convertible Notes of 80.7735 ADSs per $1,000 principal amount of the Convertible Notes is equal to the quotient of (x) 1,000 divided by (y) the initial conversion price of U.S.$12.3803, rounded to the nearest 1/10,000th of an ADS.

After taking into account the 5 Day Average VWAP of U.S.$9.5233, the final version of the make-whole table for the Convertible Notes, which sets forth the number of additional ADSs to be added to the conversion rate for conversions of the Convertible Notes in connection with a Fundamental Change, as defined in the indenture governing the Convertible Notes (the “Indenture”), is set forth below.

The ADS prices set forth in the column headings of the table below will be adjusted as of any date on which the conversion rate of the Convertible Notes is otherwise adjusted. The adjusted ADS prices will equal the ADS prices immediately prior to such adjustment, multiplied by a fraction, the numerator of which is the conversion rate immediately prior to the adjustment giving rise to the ADS price adjustment, and the denominator of which is the conversion rate as so adjusted. The number of additional ADSs will be adjusted in the same manner as the conversion rate is otherwise adjusted.

If the exact ADS prices and effective dates are not set forth in the make-whole table and the ADS price is:

• (1) between two adjacent ADS price amounts in the make-whole table or the effective date is between two adjacent effective dates in the make-whole table, the number of additional ADSs will be determined by a straight-line interpolation between the number of additional ADSs set forth for the higher and lower ADS price amounts and the two dates based on a 365-day year, as applicable.
• (2) greater than U.S.$28.57 per ADS (subject to adjustment in the same manner as the ADS prices set forth in the column headings of the make-whole table), no additional ADSs will be issued upon conversion.
• (3) less than U.S.$9.52 per ADS (subject to adjustment in the same manner as the ADS prices set forth in the column headings of the make-whole table), no additional ADSs will be issued upon conversion.

Notwithstanding the foregoing, in no event will the total number of ADSs issuable upon conversion of U.S.$1,000 principal amount of the Convertible Notes exceed 116.0714 ADSs, subject to adjustment for events from and after September 26, 2014 in the same manner as the conversion rate as set forth in section 12.05(a) of the Indenture.
