CEMEX, S.A.B. de C.V. (NYSE: CX) announced today that consolidated net sales increased 8% in the third quarter of 2006 to US$4.65 billion. EBITDA in the third quarter of 2006 grew 10% to US$1.11 billion.

CEMEX Consolidated Third Quarter Financial and Operational Highlights

• EBITDA (operating income plus depreciation and amortization) increased to US$1.11 billion, 10% more than the US$1.01 billion achieved in the third quarter of 2005.
• Free cash flow after maintenance capital expenditures was US$816 million, 11% more than in third quarter 2005.
• Sales increased in the majority of CEMEX's markets due to higher cement, ready-mix, and aggregates volumes. Public infrastructure and housing continue to be the main drivers of cement and ready-mix demand in most of our markets.
• Operating income increased 6% during the quarter, to US$821 million in the third quarter of 2006 from US$771 million in the third quarter of last year.
• CEMEX's consolidated cement volume increased 3%, reaching 22.3 million metric tons.

Hector Medina, Executive Vice President of Planning and Finance, said: "CEMEX continues to make progress in generating profitability across the entire value chain. In the third quarter, net sales increased in the majority of our markets, as public infrastructure and housing continue to drive cement and ready-mix demand. We remain confident in our ability to deliver consistent returns and continued growth in most of our businesses."

Consolidated Corporate Results

In the third quarter of 2006, majority net income increased 24% to US$836 million from US$675 million in the third quarter of 2005. The increase in majority net income for the quarter is primarily the result of stronger operating performance, the recognition of the extraordinary gain from the sale of Semen Gresik, and foreign-exchange and financial-instrument gains.

Net debt at the end of the third quarter was US$7.14 billion, representing reductions of US$976 million during the quarter and US$3.3 billion since the end of first quarter 2005. The net-debt-to-EBITDA ratio decreased to 1.8 times from 2.1 times at the end of the second quarter in 2006. Interest coverage reached 8.3 times during the quarter, up from 6.5 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.
