                  CEMEX'S THIRD QUARTER 2006 SALES INCREASE 8%;
                                 EBITDA UP 10%

MONTERREY, MEXICO, October 25, 2006 - 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
---------------------------------------------------------------------

     o   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.

     o   Free cash flow after maintenance capital expenditures was US$816
         million, 11% more than in third quarter 2005.

o        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.

     o   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.

     o   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.

This press release contains forward-looking statements and information that are
necessarily subject to risks, uncertainties and assumptions. Many factors could
cause the actual results, performance or achievements of CEMEX to be materially
different from those expressed or implied in this release, including, among
others, changes in general economic, political, governmental and business
conditions globally and in the countries in which CEMEX does business, changes
in interest rates, changes in inflation rates, changes in exchange rates, the
level of construction generally, changes in cement demand and prices, changes in
raw material and energy prices, changes in business strategy and various other
factors. Should one or more of these risks or uncertainties materialize, or
should underlying assumptions prove incorrect, actual results may vary
materially from those described herein. CEMEX assumes no obligation to update or

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. EBITDA and Free
Cash Flow should not be considered as indicators of CEMEX's financial
performance, as alternatives to cash flow, as measures of liquidity or as being
comparable to other similarly titled measures of other companies.
