• Fourth-Quarter 2006 Net Sales Increased 13%; EBITDA Rose 4%

CEMEX, S.A.B. de C.V. (NYSE: CX), announced today that consolidated net sales increased 13% in the fourth quarter of 2006 to US$4.5 billion and were up 19% for the full year reaching US$18.2 billion versus the comparable periods in 2005. EBITDA grew 4% in the fourth quarter of 2006 to US$934 million and 16% to US$4.1 billion for the full year.

CEMEX's Consolidated Fourth-Quarter and Full-Year Financial and Operational Highlights

• Sales increased in the majority of CEMEX's markets due to higher cement, ready-mix, and aggregates volumes and better supply-demand dynamics. The main drivers of demand in most markets continued to be public infrastructure and housing.
• Free cash flow after maintenance capital expenditures for the quarter was US$570 million, up 53% from US$373 million in the same quarter of 2005. For the full-year 2006, free cash flow after maintenance capital expenditures was up 22% to US$2.7 billion versus US$2.2 billion in 2005.
• Operating income in the fourth quarter increased 21%, to US$611 million, from the comparable period in 2005 and increased 18% to US$2.9 billion for the full-year 2006 versus US$2.5 billion in 2005.
• EBITDA (operating income plus depreciation and amortization) increased to US$934 million, 4% more than the US$901 million achieved in the fourth quarter of 2005. For the full year 2006, EBITDA grew 16% to US$4.1 billion versus US$3.6 billion in 2005.

Hector Medina, Executive Vice President of Planning and Finance, said: "2006 was an outstanding year for CEMEX. We celebrated our 100-year anniversary and achieved record financial results driven by our international presence and global diversification strategy. Despite the current slowdown in the U.S. residential sector, we experienced strong double-digit sales growth during the quarter both overall and in the majority of our key markets. As we look ahead to 2007, and with the integration of RMC fully completed, we are well positioned to grow and continue to capitalize on the macroeconomic trends driving the industry."

Consolidated Corporate Results

In the fourth quarter of 2006, majority net income increased 55% to US$377 million from US$244 million in the fourth quarter of 2005. For the full-year 2006, majority net income increased 13%, reaching US$2.4 billion. The increase in majority net income for the quarter is due primarily to lower depreciation and amortization expense and higher foreign-exchange and financial-instrument gains.

Net debt at the end of the fourth quarter was US$5.8 billion, representing reductions of US$1.33 billion during the quarter and US$2.85 billion for the full year 2006. The net-debt-to-EBITDA ratio decreased to 1.4 times from 1.8 times at the end of third quarter 2006. Interest coverage reached 8.4 times during the quarter, up from 6.8 times a year ago.

EBITDA is defined as operating income plus depreciation and amortization. Free Cash Flow is defined as EBITDA minus net interest expense, maintenance and expansion capital expenditures, change in working capital, taxes paid, and other cash items (net other expenses less proceeds from the disposal of obsolete and/or substantially depleted operating fixed assets that are no longer in operation). Net debt is defined as total debt minus the fair value of cross-currency swaps associated with debt minus cash and cash equivalents. The net debt to EBITDA ratio is calculated by dividing net debt at the end of the quarter by EBITDA for the last twelve months. All of the above items are presented under generally accepted accounting principles in Mexico. EBITDA and Free Cash Flow (as defined above) are presented herein because CEMEX believes that they are widely accepted as financial indicators of CEMEX's ability to internally fund capital expenditures and service or incur debt.
