                        EBITDA UP 16%; SALES INCREASE 5%

MONTERREY, MEXICO, July 25, 2006 - CEMEX, S.A.B. de C.V. (NYSE: CX) announced
today that EBITDA increased 16% in the second quarter of 2006 to US$1.14
billion. Consolidated net sales in the second quarter of 2006 grew 5% to US$4.6
billion.

CEMEX Consolidated Second-Quarter Financial and Operational Highlights
----------------------------------------------------------------------

o    EBITDA (operating income plus depreciation and amortization) increased to
     US$1.14 billion, an increase of 16% over US$989 million achieved in the
     second quarter of 2005.

o    Free cash flow after maintenance capital expenditures was US$779 million,
     an increase of 5% over the second quarter of last year.

o    Increased sales in the majority of CEMEX's markets were the result of to
     higher demand for cement, ready-mix, and aggregates. Public infrastructure
     and housing continue to be the main drivers of cement and ready-mix demand
     in the majority of CEMEX's markets.

o    Operating income for the second quarter increased 15% to US$861 million
     over US$751 million in the comparable period in 2005.

o    CEMEX's consolidated cement volume increased 3% to 22.4 million metric
     tons, while consolidated ready-mix and aggregates volumes fell 6% and 9%
     respectively.

Hector Medina, Executive Vice President of Planning and Finance, said: "We
continue to be encouraged by our post-consolidation performance. Our solid
performance during the first half of the year resulted primarily from the
strength of our operations in most of our core markets, as well as from the
realization of the RMC synergies that further enhanced this growth. As we look
forward to the second half of the year, we remain optimistic about our ability
to continue to drive solid returns for our shareholders."

representing reductions of US$343 million during the quarter, and US$2.3 billion

Consolidated net sales grew to US$4,614 million, representing an increase of 5%
over those of second quarter 2005. Sales increased in most of our markets due to
higher cement, ready-mix, and aggregates volumes and a better pricing
environment. Public infrastructure and housing continue to be the main drivers
of cement and ready-mix demand in most of our markets.

Operating income increased 15% during the quarter, from US$751 million in the
second quarter of last year to US$861 in the second quarter of 2006.

Similarly, EBITDA increased 16% in the quarter compared to the same period last
year, reaching US$1,143 million. EBITDA as a percentage of sales increased 2.2
percentage points, from 22.6% in second quarter 2005 to 24.8% in second quarter
2006. Improved operating income and EBITDA margins are due to synergies realized
as a result of RMC-integration initiatives, and better supply-demand dynamics in
most markets, which more than offset higher energy and transportation costs.

Foreign-exchange gain (loss) and gain (loss) on financial instruments for the
quarter resulted in losses of US$48 million and US$93 million, respectively. The
entire losses are the result of intercompany transactions and are due to the
depreciation of the Mexican peso during the quarter.

Majority net income decreased 21% to US$579 million in the second quarter of
2006 from US$733 million in the same period a year ago. The decrease in majority
net income for the quarter comes mainly from higher foreign-exchange and
financial-instrument losses partially mitigated by stronger operating
performance, as described above.

Net debt at the end of the second quarter was US$8,120 million, representing
reductions of US$343 million during the quarter and US$2,315 million since the
end of first quarter 2005. The net-debt-to-EBITDA ratio decreased to 2.1 times
from 2.3 times at the end of first quarter 2006. Interest coverage reached 7.7
times during the quarter, up from 6.5 times a year ago.

During the second quarter, CEMEX, under its Medium-Term Promissory Notes Program
("Certificados Bursatiles"), issued notes for MXN1.5 billion with a maturity of
five years at an interest rate equal to the 91-day Mexican treasury (CETES) plus
53 basis points. CEMEX also issued various short-term notes under its Short-Term
Promissory Notes Program ("Certificados Bursatiles"), having an outstanding
amount of MXN927 at the end of the quarter. All notes issued were swapped to US
dollars at rates lower than LIBOR.

In addition, CEMEX and some of its subsidiaries amended various credit
facilities totaling US$4.7 billion, extending their maturities and reducing
their cost.

----------------------------------
(1)  EBITDA and free cash flow (calculated as set forth above) are presented
     herein because CEMEX believes that they are widely accepted as financial
     indicators of its ability to internally fund capital expenditures and to
     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. EBITDA is reconciled above to operating
     income, which CEMEX considers to be the most comparable measure as
     determined under generally accepted accounting principles in Mexico
     (Mexican GAAP). Free cash flow is reconciled to EBITDA. CEMEX is not
     required to prepare a statement of cash flows under Mexican accounting
     principles and, as such, does not have such Mexican-GAAP cash-flow measures
     to present as comparable to EBITDA or free cash flow.

(2)  During 2004, the Mexican Institute of Public Accountants issued Bulletin
     C-10, "Derivative Financial Instruments and Hedging Activities", which
     became effective beginning January 1, 2005. Bulletin C-10 details and
     supplements issues related to the accounting of derivative financial
     instruments. Among other aspects, Bulletin C-10 precludes the presentation
     of two financial instruments as if they were a single instrument (synthetic
     presentation). For this reason, starting in 2005, CEMEX recognizes the
     assets and liabilities resulting from the fair value of cross-currency
     swaps ("CCS") separately from the financial debt, and such debt is
     presented in the currencies originally negotiated. Starting in 2001, CEMEX
     has effectively changed the original profile of interest rates and
     currencies of financial debt associated to CCS, and accordingly, until
     December 31, 2004, financial debt subject to these instruments was
     presented in the currencies negotiated in the CCS, through the recognition
     within debt of a portion of the assets or liabilities resulting from the
     fair value of such CCS. This reclassification has no impact on
     stockholders' equity or net income. For presentation purposes in the table
     above, net debt includes the fair value of CCS associated with debt.

As of June 30, 2006, executives had outstanding options on a total of
111,932,026 CPOs, with a weighted-average strike price of US$1.45 per CPO
(equivalent to US$14.50 per ADR). Starting in 2005, CEMEX began offering
executives a stock-ownership program. As of June 30, 2006, our executives held
188,820,818 restricted CPOs, representing 2.6% of our total CPOs outstanding.


Derivative Instruments
--------------------------------------------------------------------------------

CEMEX periodically utilizes derivative financial instruments such as
interest-rate and currency swaps, currency forwards and options, and equity
derivatives in order to execute its corporate financing strategy and to hedge
other obligations as they arise. The following table shows the notional amount
for each type of derivative instrument and the aggregate fair market value for
all of CEMEX's derivative instruments as of the last day of each quarter
presented.

In millions of US dollars.

The estimated aggregate fair market value represents the approximate settlement
result as of the valuation date, based upon quoted market prices and estimated
settlement costs, which fluctuate over time. Fair market values and notional
amounts do not represent amounts of cash currently exchanged between the
parties; cash amounts will be determined upon termination of the contracts
considering the notional amounts and quoted market prices as well as other
derivative items as of the settlement date. Fair market values should not be
viewed in isolation but rather in relation to the fair market values of the
underlying hedge transactions and the overall reduction in CEMEX's exposure to
the risks being hedged.

Note: Mexican GAAP ("Bulletin C-2") requires companies to recognize all
derivative financial instruments in the balance sheet as assets or liabilities,
at their estimated fair market value, with changes in such fair market values
recorded on the income statement. The exceptions to the general rule until
December 31, 2004, as they pertained to CEMEX, occurred when transactions were
entered into for cash-flow hedging purposes. In such cases, changes in the fair
market value of the related derivative instruments were recognized temporarily
in equity and were reclassified into earnings as the inverse effects of the
underlying hedged items flowed through the income statement. Beginning in 2005,
new Bulletin C-10, "Derivative Financial Instruments and Hedging Activities",
establishes the framework for hedge accounting and overrides Bulletin C-2 in
this respect; however, in respect to cash-flow hedges, the new rules are the
same as those applied by CEMEX since 2001. CEMEX has recognized increases in
assets and liabilities, which resulted in a net asset of US$165 million, arising
from the fair market value recognition of its derivatives portfolio as of June
30, 2006. The notional amounts of derivatives substantially match the amounts of
underlying assets, liabilities, or equity transactions on which the derivatives
are being entered into.

--------------------------------
(1)  Until September 27, 2005, the date of pricing of our nondilutive equity
     offering and the liquidation of the equity forward contracts that hedged
     our executive stock-option programs, CEMEX accrued a liability representing
     the intrinsic value of the stock options. Resulting from the elimination of
     the economic hedge and given that the potential future appreciation of the
     stock options is currently not hedged through equity forwards, CEMEX has
     decided, for purposes of determining its obligations under the stock-option
     programs, to move from intrinsic value to fair value.

(2)  As of June 30, 2006, CEMEX had recognized a net liability related to its
     stock-option programs of approximately US$101 million. This liability
     includes the fair value of the options for US$237 million, net of an
     investment in a derivative financial instrument of approximately US$136
     million that guarantees us the receipt of cash equivalent to the
     appreciation of our CPO market price over 48 million CPOs (considering the
     effect of the two-for-one CPO split effective July 17, 2006), in order to
     meet our obligations under our executive stock-option programs.

(3)  Estimated aggregate fair market value as of July 24, 2006, is US$381
     million.

Other Activities
--------------------------------------------------------------------------------

CEMEX CPO and ADS two-for-one split

On July 11, 2006, CEMEX announced that beginning on July 17, 2006, trading in
its Ordinary Participation Certificates ("CPOs") and beginning on July 24, 2006,
trading in its American Depositary Shares ("ADSs") started reflecting its
previously announced two-for-one stock split.

In connection with the stock split, which was approved by CEMEX's shareholders
on April 27, 2006, each of CEMEX's existing series A shares was surrendered in
exchange for two new series A shares, and each of CEMEX's existing series B
shares was surrendered in exchange for two new series B shares. Each CPO, which
represented two existing series A shares and one existing series B share, was
surrendered in exchange for two new CPOs. Each new CPO represents two new series
A shares and one new series B share.

Beginning on July 24, 2006, trading on the New York Stock Exchange started
reflecting the stock split as each ADS holder received one additional ADS for
every existing ADS, each representing ten new CPOs. During the period between
July 17 and July 21, 2006, the number of CEMEX's existing ADSs, each of which
previously represented ten CPOs, did not change; instead it included the right
to receive an additional ADS on July 24, 2006.

The proportional equity interest participation of existing shareholders in both
CPOs and ADSs does not change as a result of the stock split.


97.4% of shareholders to receive CPOs or ADSs under CEMEX's stock dividend
program

On June 5, 2006, CEMEX announced the completion of its stock dividend program
determined at the Shareholders Meeting on April 27, 2006. A total of 105,937,857
CPOs, including CPOs in the form of ADSs (one ADS represents ten CPOs), were
issued on June 5, 2006, and were distributed to 97.4% of shareholders; the
remaining 2.6%, consisting of CPO holders, received a cash payment of MXN1.4887
per CPO in lieu of the stock dividend, for a total of approximately MXN144
million (US$13 million) paid by CEMEX.

Under this stock dividend program, CEMEX shareholders received one new CPO for
each 35.2895 CPOs held (each representing two series A shares and one series B
share), and ADS holders received one new ADS for each 35.2895 ADSs held.

CPO holders had the option to receive a cash payment in lieu of the stock
dividend. ADS holders were entitled to receive a stock dividend only. ADS
holders were entitled to instruct the ADS Depositary to sell all or a portion of
the additional stock received as a result of the stock dividend into the market
and receive the net cash proceeds from such sales.

(CPO amounts and cash payment per CPO do not reflect the two-for-one CPO split
effective July 17, 2006, nor do they reflect the two-for-one ADR split effective
July 24, 2006).


CEMEX to divest stake in Semen Gresik

On May 4, 2006, CEMEX announced that it agreed to sell 24.9% of PT Semen Gresik
to Indonesia-based Rajawali Group. PT Semen Gresik is a publicly traded company
on the Jakarta Stock Exchange and trades under the ticker symbol "SMGR".

According to the terms of the agreement, Rajawali Group will pay CEMEX US$337
million, or US$2.28 per share. As of July 25, all conditions precedent prior to
closing have been met. We expect to receive the proceeds from this sale during
July 2006 and we intend to use such proceeds to accelerate the pace of debt
reduction.

Operating Results
--------------------------------------------------------------------------------

Mexico

Our Mexican operations' cement volumes increased 6% during the quarter versus
second quarter 2005, and ready-mix volumes increased 20% over the same period.
For the first six months of the year, cement and ready-mix volumes increased 8%
and 23%, respectively, versus the comparable periods a year ago. Cement prices
were 2% higher in US-dollar terms during the quarter versus the same period a
year ago and have increased 5% year to date versus the first half of 2005.
Ready-mix prices, in US-dollar terms, were 4% higher during the first half of
the year versus the same period in 2005.

Government infrastructure projects, including street and highways, state
infrastructure, and rebuilding efforts, are driving cement consumption. The
formal residential sector continues to benefit from credit availability from
commercial banks and noncommercial sources such as Infonavit. Cement demand from
the self-construction sector showed a slight recovery during the quarter due to
increased disposable income, despite the fact that the formal sector attracted
customers through government-financed mortgages.

United States

In CEMEX's US operations, on a like-to-like basis for the ongoing operations,
cement volumes decreased 3%, ready-mix volumes decreased 16%, and aggregates
volumes decreased 21%, during the second quarter compared with the second
quarter 2005.

The decline during the second quarter was driven mainly by a weaker residential
sector and unfavorable weather conditions in the western region. It was also
affected by a shift in consumption from the second quarter to the first quarter
due to favorable weather conditions in the first three months of the year.

For the first six months of the year and on a like-to-like basis, cement volumes
increased 6%, ready-mix volumes decreased 8%, and aggregates volumes decreased
11% versus the first six months of 2005.

Construction spending in the residential sector was up 6% for the first five
months of the year while housing starts decreased by 2% in the same period.
Public-sector construction spending put in place was up 10% for the first five
months of 2006, with spending for streets and highways up 15% as well.
Construction put in place in the industrial-and-commercial sector increased 14%
during the first five months of the year.

Cement prices increased 16% during the second quarter versus the same quarter
last year. Ready-mix and aggregate prices, on a like-to-like basis for the
ongoing operations, increased 19% and 37%, respectively, during the quarter
versus the second quarter of 2005.

Spain

Domestic cement volume increased 6% during the second quarter of 2006 over the
same quarter in 2005. Ready-mix volumes, adjusted for the integration of the
Readymix Asland assets after the termination of the joint venture with Lafarge
in December 2005, increased 6% during the second quarter versus the comparable
period a year ago. For the first half of the year, cement volumes increased 9%
and adjusted ready-mix volumes increased 13%.

The infrastructure and residential sectors continue to drive cement demand in
Spain. There are new projects from the government's infrastructure program, and
public spending continues in anticipation of next year's local elections. The
residential sector showed strong performance during the first half of the year.
Prices for domestic cement increased 10% in US-dollar terms and 8% in euro terms
for the second quarter versus the comparable period in 2005.

United Kingdom

Cement and ready-mix volumes in the United Kingdom decreased 14% and 5%,
respectively, for the second quarter of 2006 versus the comparable period in
2005. For the first six months of the year, cement volumes decreased 7% while
ready-mix volumes remained flat versus the first half of 2005. Cement prices, on
a like-to-like basis for the ongoing operations, increased 7% in US-dollar terms
and 10% in British-pound terms during the first half of this year versus the
comparable period in 2005.

Cement volume sales were affected by enhancements that were made at the Rugby
plant and that resulted in below-average kiln output for the quarter.
Unfavorable weather conditions also affected cement consumption during the month
of May. Favorable activity in public housing and industrial-and-commercial
sectors has partly mitigated the slowdown in infrastructure, private new
housing, and repair-and-maintenance work.

Operating Results
--------------------------------------------------------------------------------

Rest of Europe

In France, ready-mix and aggregates volumes decreased 1% and 2%, respectively,
during the second quarter versus the same quarter of last year. For the first
six months of the year, ready-mix and aggregates volumes increased 5% and 4%,
respectively versus the same period of 2005. Prices for ready mix and aggregates
in euro terms increased 5% and 4%, respectively, during the first half of the
year. The residential sector, including private and public housing, continues to
be the main driver of consumption.

In Germany, domestic cement volumes increased 11%, both in the second quarter
and in the first half of 2006 versus the comparable periods of last year.
Domestic cement prices increased 5% in euro terms during the first half of the
year. Residential permits increased 25% in the January-April period due to new
house owners planning ahead in order to take advantage of the home-owner subsidy
that was cancelled in December 2005 as well as to avoid the 3% value-added-tax
rate increase, which becomes effective in 2007. Permits for nonresidential
construction started to increase in February, benefiting from the economic
upswing and in response to a favorable business climate. The public-works sector
is starting to show a positive trend as a result of the government's new
transportation-infrastructure program.


South/Central America and Caribbean

Domestic cement volumes in the region increased 10% during the quarter and 14%
for the first six months of the year versus the same periods of 2005. Average
prices in US-dollar terms remained flat for the quarter compared with the same
period of last year.

The main drivers of cement consumption in Venezuela continue to be the
residential sector - including formal and self-construction housing - and
infrastructure spending, which continues to benefit from increased oil revenues.
Cement volumes in the country increased 32% during the first half of 2006 versus
the same period in 2005.

In Colombia, cement volumes decreased 7% during the second quarter and remained
flat in the first half of the year versus the comparable periods of last year.
The main drivers of cement in the country are public infrastructure and
nonresidential construction. The self-construction sector is starting to level
off after a significant increase last year. Cement prices increased 16% in
US-dollar terms during the quarter compared with the second quarter of last
year.


Africa and Middle East

The region's domestic cement volumes for the second quarter and for the first
half of 2006 increased 8% and 11%, respectively, versus the comparable periods
of last year. Average prices in US-dollar terms increased 21% during the quarter
versus second quarter 2005.

Domestic cement volumes for our operations in Egypt increased 8% during the
second quarter compared with the same quarter in 2005. The favorable economic
environment in the country translates into higher construction spending and
cement consumption. Higher remittances into the country are also having a
positive impact on the self-construction sector.


Asia

In aggregate, our cement volumes in the region decreased 4% during both the
quarter and the first half of the year versus the comparable periods of last
year. Average prices in US-dollar terms increased 10% during the quarter
compared with second quarter 2005.

Domestic cement volume in the Philippines decreased 10% during the second
quarter and 8% during the first half of 2006 versus the comparable periods in
2005. The Philippine Congress did not approve the 2006 national budget, delaying
public infrastructure spending. The main drivers of demand continued to be the
residential, commercial, and self-construction sectors.

Methodology for consolidation and presentation of results

CEMEX consolidates its results in Mexican pesos under Mexican generally accepted
accounting principles (GAAP). For the reader's convenience, US dollar amounts
for the consolidated entity are calculated by converting the constant Mexican
peso amounts at the end of each quarter using the period-end MXN/USD exchange
rate for each quarter. The exchange rates used to convert results for second
quarter 2006, first quarter 2006, and second quarter 2005 are 11.26, 10.88, and
10.75 Mexican pesos per US dollar, respectively. CEMEX's weighted-average
inflation factor between June 30, 2005, and June 30, 2006, was 8.52%.

Per-country/region figures are presented in US dollars for the reader's
convenience. In the consolidation process, each country's figures (except those
of CEMEX Mexico) are converted to US dollars and then to Mexican pesos under
Mexican GAAP. Figures presented in US dollars for Mexico, Spain, and the United
Kingdom as of June 30, 2006, and June 30, 2005, can be converted into their
original local currency amount by multiplying the US-dollar figure by the
corresponding exchange rate provided below.

To convert June 30, 2005, US-dollar figures for Mexico to constant Mexican pesos
as of June 30, 2006, it is necessary to first convert the June 30, 2005,
US-dollar figure to Mexican pesos using the exchange rate provided below, and

Definition of terms

EBITDA equals operating income plus depreciation and operating amortization.

Free cash flow equals 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).

Maintenance capital expenditures consist of maintenance spending on our cement,
ready-mix, and other core businesses in existing markets.

Expansion capital expenditures consist of expansion spending on our cement,
ready-mix, and other core businesses in existing markets.

Working capital equals operating accounts receivable (including other current
assets received as payment in kind) plus historical inventories minus operating
payables.

Net debt equals total debt minus the fair value of cross-currency swaps
associated with debt minus cash and cash equivalents (please refer to footnote 2
on the second page of this report for further details).

Interest coverage is calculated by dividing EBITDA for the last twelve months by
interest expense for the last twelve months.

Net debt/EBITDA is calculated by dividing net debt at the end of the quarter by
EBITDA for the last twelve months (please refer to footnote 2 on the second page
of this report for further details).

Effect of the purchase of RMC on our financial statements

The acquisition of RMC concluded on March 1, 2005. The process of allocating the
purchase price paid for RMC's shares of approximately US$4.2 billion, including
other direct purchase costs net of the proceeds from the sale of some assets, to
the fair value of the assets acquired and liabilities assumed began during March
2005 and continued through the year and the first quarter of 2006. As of June,
30, 2006, CEMEX considers that the difference between the purchase price paid
and the fair value of RMC's net assets as of March 1, 2005, which represented
goodwill of approximately US$1.4 billion, is a reasonable estimate of the final
allocation process. At this stage, CEMEX does not consider the existence of any
material pending issues with respect to the purchase-price allocation.
