                           BUILDING THE FUTURE(TM)


            CEMEX'S FIRST QUARTER 2004 OPERATING INCOME GROWS 31%;
                        FREE CASH FLOW INCREASES 198%


MONTERREY, MEXICO, April 22, 2004 - CEMEX, S.A. de C.V. (NYSE: CX) announced
today that its consolidated net sales for the first quarter of 2004 were
US$1.8 billion, up 13% in dollar terms compared to the same period of 2003.
The expansion of the global economy led to increased cement and ready mix
demand in most of our markets. Public spending on infrastructure and housing
continue to be the main drivers of cement demand in our markets. In real peso
terms, net sales grew 9%, to MXP20.1 billion.

Our consolidated cement sales volume during the quarter was 15.7 million
metric tons, up 6% compared to the first quarter of 2003, while ready-mix
volumes were 11% higher at 5.6 million cubic meters.

Free cash flow for the first quarter increased 198% in dollar terms compared
with the same quarter of 2003, reaching US$289 million. EBITDA (operating
income plus depreciation and amortization) grew 24% to US$557 million. Our
consolidated EBITDA margin grew to 30.8% in the first quarter from 28.2%
during the same period of last year. The three percentage-point increase is
due mainly to higher sales volumes, better pricing in most of our markets, and
lower costs of goods sold and SG&A as percentage of sales. In real peso terms,
EBITDA was MXP6.2 billion, up 19% compared to the same quarter of 2003.

Hector Medina, Executive Vice President of Planning and Finance, said "We are
very pleased with our first quarter performance, which strongly indicates our
emergence from the trough of the business cycle in most of our portfolio. We
continue to believe that debt reduction is the best way to create shareholder
value in the absence of investments that meet our strict capital allocation
criteria; we will continue to favor using our free cash flow to de-leverage in
the near term".

First-quarter operating income increased 31% in dollar terms, to US$393
million. In real peso terms, operating income grew 26% to MXP4.4 billion. Our
selling, general and administrative expenses (SG&A) as a percentage of net
sales decreased 1.3 percentage points versus the same period in 2003. The
improved SG&A margin is due to our ongoing cost-reduction initiatives, which
lowered costs significantly at the corporate and operating levels.

Majority net income for the first quarter was US$311 million (US$0.96 per
ADR), up 282% compared to the same period of 2003. The increase was due mainly
to stronger operating performance, and better results in foreign exchange and
marketable securities. In real peso terms, majority net income grew 269% to
MXP3.5 billion.

At the end of the quarter, our net debt was US$5,352 million, representing a
reduction of 13% compared to that at the end of the first quarter of 2003. Our
net debt to EBITDA ratio reached 2.4 times, versus 2.7 times three months ago,
and 3.2 times twelve months ago. Free cash flow in the amount of US$289
million was used to reduce debt during the quarter.

CEMEX's interest coverage (EBITDA divided by interest expense plus preferred
dividends, all for the last twelve months) was 5.7 times, versus 5.0 times a
year ago.

CEMEX's Mexican operations reported net sales of US$697 million in the first
quarter, a 10% growth versus the same period of 2003. EBITDA increased 13%, to
US$316 million. Domestic cement sales volumes increased 7% for the quarter
versus the same period of last year. The self-construction sector began
showing moderate growth during the quarter, while public spending in
infrastructure, and the housing sector remain strong. The industrial and
commercial sectors of the economy remain a stable source of cement and
ready-mix demand.

In the United States, CEMEX's net sales were US$404 million, an increase of
16% compared to the year-earlier period. Quarterly EBITDA was 10% higher
year-over-year, reaching US$74 million. Cement sales volumes increased 17%
during the first quarter of 2004, compared to the year-earlier period. The
public works and residential sector continue to drive cement and ready-mix
demand. In addition, sales volumes benefited from favorable weather conditions
throughout the quarter, especially in the last three weeks of March, and a
relatively weak first quarter 2003. Ready-mix volumes increased 9% for the
quarter.

In Spain, CEMEX's net sales grew 14% in the first quarter of 2004 to US$292
million while EBITDA increased 18%, reaching US$91 million. Domestic cement
volume decreased 2% and ready-mix volume remained flat for the quarter versus
the year-earlier period. Unfavorable weather conditions in March were
responsible in part for the volume decline versus the same period a year ago.
Spending on infrastructure remains at high levels due Spain's infrastructure
program, and the Spanish housing sector also remains strong.

CEMEX Venezuela reported a 48% growth in sales, reaching US$75 million. EBITDA
increased to US$31 million, 46% higher compared to the same period of 2003.
Domestic cement volumes increased 57%, while ready-mix volumes grew 31%.
Economic activity during the quarter was significantly stronger than that in
the same period of 2003 due to the general strike in Venezuela, which began at
the end of 2002. The self-construction sector remains as a stable source of
cement demand. Cement demand from the public works sector was moderate.

CEMEX Colombia's net sales were US$57 million, up 24% versus the year-ago
period. EBITDA, at US$34 million, increased 27%. Cement volume was up 12%
versus the first quarter of 2003, while ready-mix volume grew 33%. Cement
demand was fueled by strong self-construction and residential sectors, as well
as increased spending from the private sector. Spending on infrastructure was
weaker than in previous periods as many projects were concluded at the end of
2003.

Our operations in Central America and the Caribbean reported quarterly net
sales of US$156 million, up 8% vis-a-vis the first quarter of 2003. EBITDA
grew 38%, reaching US$47 million. Cement volume decreased 1% and ready-mix
volume for the quarter grew 12%.

CEMEX Egypt's sales increased 64%, to US$43 million while domestic cement
volumes decreased 12% versus the first quarter of 2003. EBITDA grew 148%
reaching US$19 million. The decrease in cement volumes is due in part to high
cement volumes, driven by a low price environment, during the first quarter of
2003.. The infrastructure sector remained stable during the quarter, while
cement demand from the private sector decreased slightly.

Our Asian operations, which include the Philippines, Thailand, Taiwan and
Bangladesh, posted net sales of US$50 million, 1% lower than those during the
same quarter of 2003. Domestic cement volumes declined 11%. EBITDA for the
first quarter of 2004 was US$14 million, 184% higher compared to the same
period of 2003 due mainly to better dollar pricing and a reduction in SG&A
expenses.

products, with operations concentrated in the world's most dynamic cement
markets across four continents. CEMEX combines a deep knowledge of the local
markets with its global network and information technology systems to provide

             ----------------------------------------------------

EBITDA is defined as operating income plus depreciation and amortization. Free
Cash Flow is defined as EBITDA minus net interest expense, capital
expenditures, change in working capital, taxes paid, dividends on preferred
equity and other cash items. Net debt is defined as total debt plus equity
obligations minus cash and cash equivalents. 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.

Consolidated net sales increased 13% over first quarter 2003 to US$1,809
million. The expansion of the global economy led to increased cement and
ready-mix demand in most of our markets. Our consolidated cement and ready-mix
volumes increased 6% and 11%, respectively, versus first quarter of 2003, and
cement prices in dollar terms increased in most of our markets. Public
infrastructure spending and housing continue to be the main drivers of cement
demand in our markets.

Cost of goods sold as a percentage of net sales decreased 1.6 percentage
points versus first quarter 2003, due mainly to lower fuels costs, and higher
average sales prices.

Selling, general and administrative expenses (SG&A) as a percentage of net
sales during the quarter decreased 1.3 percentage points versus the same
period in 2003. The improved SG&A margin is due mainly to our ongoing
cost-reduction initiatives which lowered costs significantly at the corporate
and operating levels.

EBITDA reached US$557 million, representing an increase of 24% over first
quarter 2003. Our consolidated EBITDA margin increased three
percentage-points, to 31% from 28% in the same period of 2003. The increase is
due mainly to higher sales volumes, better pricing in most of our markets, and
a lower cost structure.

Foreign exchange gain (loss) for the quarter was a gain of US$12 million,
versus a loss of US$69 million in first quarter 2003. The gain was due mainly
to the appreciation of the Mexican peso against the U.S. dollar.

Marketable securities gain (loss) for the quarter was a loss of US$11 million,
versus a loss of US$105 million in first quarter 2003. As dollar interest
rates dropped during the quarter, the value of some of our derivative
instruments, which we put in place to lock in a fixed interest rate,
decreased. A portion of the valuation result of these instruments is
recognized in our income statement.

Majority net income for the quarter was US$311 million, versus US$81 million
in the first quarter of 2003. The increase was due mainly to our stronger
operating performance, and better results in foreign exchange and marketable
securities.

Net debt at the end of the first quarter was US$5,352 million, representing a
decrease of 13% compared to that at the end of the first quarter of 2003. The
ratio of net debt to EBITDA reached 2.4 times, versus 2.7 times three months
ago, and 3.2 times twelve months ago. Free cash flow in the amount of US$289
million was used to reduce debt during the quarter.

During the quarter, US$289 million of free cash flow was used to reduce debt. Additionally, cash in the amount of US$46 million resulting from the difference between interest accrued and interest paid during the quarter, as well as from other non-operating sources was used to purchase our warrants through our recent tender offer. 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 (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 GAAP cash flow measures to present as comparable to EBITDA or free cash flow.

Effective January 1, 2004, resulting from a new regulation under Mexican GAAP, the approximately US$66 million balance of preferred capital securities is now treated as a liability, and not as a minority interest, and its preferred dividend as financial expense. Other developments On March 30, 2004, CEMEX, through its Spanish subsidiary CEMEX Espana, entered into a EUR 400 million multicurrency credit facility. The facility is divided into three tranches: The first tranche is a 364-day revolving credit facility; the second tranche is a five-year, multi-currency term loan; and the third tranche is a five-year yen-denominated term loan with a fixed interest rate. The transaction attracted commitments from 27 financial institutions and had an over-subscription rate in excess of 60%. In addition, CEMEX Espana, through a wholly-owned subsidiary, closed on April 15, 2004 a five and seven-year JPY 11,068 million private placement with a group of U.S.-based insurance companies and pension funds. The proceeds of these two transactions will be used to refinance short-term debt and for general corporate purposes. - -------------------------------------------------------------------------------- Please refer to the end of this report for definition of terms, U.S. dollar translation methodology Page 1 and other important disclosures.

First quarter Fourth quarter ------------------- ------------------- Notional amounts 2004 2003 2003 - --------------------------------------------------------------------------------------------------------------- Equity * 1,109 1,500 1,085 Foreign-exchange 2,654 2,750 2,893 Interest-rate 2,223 3,576 2,224 - --------------------------------------------------------------------------------------------------------------- Estimated aggregate fair market value (278) (570) (233) - --------------------------------------------------------------------------------------------------------------- In millions of U.S. 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 the other derivative items as of the settlement date. Fair market values should not be viewed in isolation but rather in relation to the fair values of the underlying hedge transactions and the overall reduction in CEMEX's exposure to the risks being hedged. * The aggregate weighted-average exercise price on March 31, 2004 for CEMEX's outstanding stock options, warrants and the CEMEX Asia Holdings obligation described in prior quarterly reports was US$25.18 per ADR. On that same date, the aggregate weighted-average strike price of CEMEX's equity forward agreements put in place to hedge its obligations under the abovementioned stock options was US$27.47 per ADR. Under Mexican GAAP ("Bulletin C-2"), companies are required 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 values recorded on the income statement. The exceptions to the rule, as they pertain to CEMEX, are presented when transactions are entered into for cash flow hedging purposes. In such cases, changes in the fair value of the related derivative instruments is recognized temporarily in equity and is reclassified into earnings as the inverse effects of the underlying hedged items flow through the income statement. CEMEX has recognized increases in assets and liabilities, which resulted in a net liability of US$538 million, arising from the fair value recognition of its derivatives portfolio as of March 31, 2004. The notional amounts of derivatives substantially match the amounts of underlying assets, liabilities or equity transactions on which the derivatives are being entered into. - -------------------------------------------------------------------------------- Please refer to the end of this report for definition of terms, U.S. dollar translation methodology Page 1 and other important disclosures.

[GRAPHIC OMITTED] //CEMEX Other Activities - -------------------------------------------------------------------------------- CEMEX successfully completes warrant tender offer On January 26, 2004, CEMEX announced the results of its offer to purchase up to 90,018,042 of its appreciation warrants, including appreciation warrants represented by American Depositary Warrants (ADWs), each ADW representing five appreciation warrants. Holders of appreciation warrants and ADWs tendered 96,641,388 appreciation warrants (including 23,575,907 appreciation warrants represented by ADWs) at prices at or below MXP 8.10 per appreciation warrant (MXP 40.50 per ADW) in the offer. In accordance with the terms of the offer, CEMEX purchased 90,018,042 appreciation warrants (including appreciation warrants represented by ADWs), representing approximately 86.73% of the 103,790,945 appreciation warrants (including appreciation warrants represented by ADWs) outstanding immediately prior to the commencement of the offer, at a final purchase price of MXP 8.10 per appreciation warrant (MXP 40.50 per ADW). The final proration factor for the offer was 93.146058%. All holders of fewer than 100 appreciation warrants or 20 ADWs who validly tendered at prices at or below the final purchase price were not subject to proration. Following the completion of the offer, approximately 11,668,132 appreciation warrants (including appreciation warrants represented by ADWs) remained held by persons other than CEMEX and its subsidiaries. - -------------------------------------------------------------------------------- Please refer to the end of this report for definition of terms, U.S. dollar translation methodology Page 1 and other important disclosures.

[GRAPHIC OMITTED] //CEMEX Operating Results - Mexico - -------------------------------------------------------------------------------- In Mexico, net sales were US$697 million, representing an increase of 10% versus first quarter 2003. Domestic gray cement volume increased 7%, and ready-mix volume also increased 7%, versus first quarter 2003. The self-construction sector began showing moderate growth during the quarter, while public infrastructure spending and the housing sector, remain strong. The industrial and commercial sector of the economy remains a stable source of cement and ready-mix demand. CEMEX's average realized gray cement price in Mexico decreased 1% in constant peso terms, and increased 1% in dollar terms, versus first quarter 2003. The average ready-mix price remained flat in constant peso terms and increased 2% in dollar terms compared to first quarter 2003. The EBITDA margin increased to 45.3% from 44.2% in the first quarter of 2003. The increase of 1.1 percentage points was due mainly to better dollar pricing and volumes of both cement and ready-mix and lower variable (primarily fuels) and fixed costs. United States - -------------------------------------------------------------------------------- Net sales for CEMEX's U.S. operations were US$404 million, representing an increase of 16% compared to first quarter 2003. Domestic cement volume increased 17%, and ready-mix volume increased 9%, compared to first quarter 2003. The public-works and residential sectors continue to drive cement and ready-mix demand. In addition, sales volumes benefited from favorable weather conditions throughout the quarter, especially in the last three weeks of March, and a relatively weak first quarter 2003. The average realized cement price decreased 1%, while the average ready-mix price increased 3%, versus first quarter 2003. The EBITDA margin decreased to 18.4% from 19.3% in the first quarter of 2003. The decease of 0.9 percentage points was due mainly to higher fuels and import costs and a change in the product mix. Spain - -------------------------------------------------------------------------------- Net sales for CEMEX Spain were US$292 million, representing an increase of 14% versus first quarter 2003. Domestic cement volume decreased 2%, while ready-mix volume remained flat, compared to first quarter 2003. Infrastructure Spending remains at a high level due to Spain's infrastructure program, and the Spanish housing sector also remains strong. Unfavorable weather conditions during the quarter were partially responsible for the volume decline versus the same period in 2003. The average domestic cement price increased 3% in euro terms and 18% in dollar terms compared to first quarter 2003. The average ready-mix price increased 4% in euro terms and 20% in dollar terms versus first quarter 2003. The EBITDA margin increased to 31.2% from 30.2% in the first quarter of 2003. The increase of 1.0 percentage point was due mainly to better cement and ready-mix prices. - -------------------------------------------------------------------------------- Please refer to the end of this report for definition of terms, U.S. dollar translation methodology Page 1 and other important disclosures.

[GRAPHIC OMITTED] //CEMEX Venezuela - -------------------------------------------------------------------------------- Net sales for CEMEX Venezuela were US$75 million, representing an increase of 48% versus first quarter 2003. Domestic cement volume increased 57%, while ready-mix volume increased 31%, compared to first quarter 2003. Economic activity during the quarter was significantly stronger than that in the same period of 2003 due to the general strike in Venezuela, which began at the end of 2002. The self-construction sector remains a stable source of cement demand. Cement demand from the public-works sector was moderate during the quarter as several infrastructure projects are currently underway. Export volume from CEMEX's Venezuelan operations increased 85% compared to first quarter 2003. Exports to North America, Central America, and the Caribbean accounted for 73%, 23% and 4%, respectively, of CEMEX Venezuela's first quarter exports. Domestic cement prices decreased 14% in constant bolivar terms and decreased 3% in dollar terms compared to first quarter 2003, while the average ready-mix price decreased 4% in constant bolivar terms, and increased 7% in dollar terms compared to first quarter 2003. The EBITDA margin decreased to 41.9% from 42.6% in the first quarter of 2003. The decrease of 0.7 percentage points was due mainly to lower cement prices. Colombia - -------------------------------------------------------------------------------- Net sales for CEMEX Colombia were US$57 million, representing an increase of 24% versus first quarter 2003. Domestic cement volume increased 12%, while ready-mix volume increased 33%, compared to first quarter 2003. Cement demand was fueled by strong self-construction and residential sectors as well as increased spending from the private sector. Infrastructure spending was weaker than in previous periods, as many projects were concluded at the end of 2003. The average realized cement price decreased 7% in Colombian peso terms and increased 2% in dollar terms versus first quarter 2003, while the average ready-mix price increased 10% in Colombian peso terms and 20% in dollar terms versus first quarter 2003. The EBITDA margin increased to 59.3% from 57.7% in the first quarter of 2003. The increase of 1.6 percentage points was due mainly to better cement and ready-mix volumes and dollar prices, which offset higher variable costs. Other Operations - -------------------------------------------------------------------------------- Net sales for our Central American and Caribbean operations increased 8% versus first quarter 2003. The increase was due to higher sales in the Caribbean region, Puerto Rico, Panama, Nicaragua and the Dominican Republic. Domestic cement volume decreased 1%, while ready-mix volume increased 12%, versus first quarter 2003. In Egypt, net sales and EBITDA increased 64% and 148%, respectively, while domestic cement volume fell 12% versus first quarter 2003. Domestic cement prices increased 63% in Egyptian pound terms and 47% in dollar terms versus first quarter 2003. The decrease in cement volumes is due in part to high cement volumes, driven by a low price environment, during the first quarter of 2003. The infrastructure sector remained stable during the quarter, while cement demand from the private sector decreased slightly. The housing sector has been affected by scarce financing and higher steel prices. Our Asian operations, which include the Philippines, Thailand, Taiwan and Bangladesh, experienced a decrease in net sales of 1% versus first quarter 2003. EBITDA was, however, 184% higher compared to first quarter of 2003 due mainly to better pricing in dollar terms. Domestic cement volume for the region decreased 11% compared to first quarter 2003. Our weighted-average domestic cement prices in the region increased 27% in dollar terms versus the same period in 2003. The EBITDA margin for the region increased to 28.2% from 9.8% in the first quarter of 2003. The increase of 18.4 percentage points was due mainly to higher cement prices and a reduction in SG&A expenses. - -------------------------------------------------------------------------------- Please refer to the end of this report for definition of terms, U.S. dollar translation methodology Page 1 and other important disclosures.

[GRAPHIC OMITTED] //CEMEX Definition of Terms and Disclosures - -------------------------------------------------------------------------------- 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, U.S. 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 Mexican peso/U.S. dollar exchange rate for each quarter. The exchange rates used to convert results for first quarter 2004, fourth quarter 2003, and first quarter 2003 are 11.12, 11.24, and 10.78 Mexican pesos per 1 U.S. dollar, respectively. CEMEX's weighted-average inflation factor between March 31, 2003, and March 31, 2004, was 6.94% Per-country figures are presented in U.S. dollars for the reader's convenience. In the consolidation process, each country's figures (except those of CEMEX Mexico) are converted to U.S. dollars and then to Mexican pesos under Mexican GAAP. Each country's figures presented in U.S. dollars at March 31, 2004, and March 31, 2003, can be converted to its original local currency amount by multiplying the U.S. dollar figure by the corresponding exchange rate provided below. To convert March 31, 2003 U.S. dollar figures for Mexico and Venezuela to constant Mexican pesos and bolivars, respectively, as of March 31, 2004, it is necessary to first convert the March 31, 2003 U.S. dollar figure to the corresponding local currency (using the exchange rates provided below), and then multiply the resulting amount by the inflation-rate factor provided in the table below. March 31 ---------------------------- Exchange rate 2004 2003 Inflation rate factor - ----------------------------------------------------------------------------------------- Mexico 11.12 10.78 1.043 Spain 0.81 0.93 Venezuela 1,920 1,600 1.236 Colombia 2,678 2,958 Egypt 6.20 5.76 - ----------------------------------------------------------------------------------------- Amounts provided in units of local currency per 1 U.S. dollar. [GRAPHIC OMITTED] //CEMEX The Central America & Caribbean region includes CEMEX's operations in Costa Rica, the Dominican Republic, Panama, Nicaragua, and Puerto Rico as well as our trading operations in the Caribbean region. The Asia region includes CEMEX's operations in the Philippines, Taiwan, Thailand, and Bangladesh. Definition of terms EBITDA equals operating income plus depreciation and operating amortization. Free cash flow equals EBITDA minus net interest expense, capital expenditures, change in working capital, taxes paid, dividends on preferred equity, and other cash expenses. Capital expenditures consist of maintenance spending on our cement and ready-mix businesses, and expansion of current cement and ready-mix facilities. Working capital equals accounts receivables plus historic inventories minus trade payables. Equity obligations for the year 2003 equaled the outstanding US$650 of preferred equity and US$66 million of capital securities. Effective January 1, 2004, the remaining US$66 million of capital securities will be treated as a liability. Net debt equals total debt plus equity obligations, minus cash and cash equivalents. Interest coverage is calculated by dividing EBITDA for the last twelve months by the sum of interest expense and preferred dividend payments for the last twelve months (all amounts in constant currency terms). Net debt/EBITDA is calculated by dividing net debt at the end of the quarter by EBITDA for the last twelve months (EBITDA in constant currency terms). Capitalization ratio is calculated by dividing total debt by the sum of total debt and consolidated stockholders' equity. Earnings per ADR The number of average ADRs outstanding used for the calculation of earnings per ADR was 324.2 million for first quarter 2004 and 304.2 million for first quarter 2003. - -------------------------------------------------------------------------------- Page 13
