Exhibit 1 Media Relations Investor Relations Analyst Relations Jorge Perez Abraham Rodriguez Ricardo Sales (52 81) 8888-4334 (52 81) 8888-4262 (212) 317-6008 CEMEX Building the futures(TM) [Logo Graphic Omitted] CEMEX'S THIRD QUARTER 2005 SALES INCREASE 110%; OPERATING INCOME UP 56% MONTERREY, MEXICO, October 21, 2005 - CEMEX, S.A. de C.V. (NYSE: CX) announced today that consolidated net sales in the third quarter of 2005 grew 110% to US$4.3 billion compared to the same quarter of 2004. This increase is primarily a result of the effect of the incorporation of RMC into CEMEX's consolidated results. CEMEX Consolidated Third-Quarter Financial and Operational Highlights - --------------------------------------------------------------------- o Sales increased in the majority of CEMEX's markets due to higher cement, ready mix and aggregates volume. Infrastructure spending remains one of the main drivers of cement and ready-mix demand throughout CEMEX's markets, as was residential construction, driven largely by the prevailing low interest rate environment worldwide. o CEMEX's consolidated cement volume increased 27% to 22 million metric tons, while consolidated ready-mix volume grew 225% to 20.2 million cubic meters. The Company's consolidated aggregates volume increased 289% to 48 million metric tons, over the third quarter of 2004. o Operating income for the third quarter increased 56% to US$771 million. o Free cash flow was US$679 million, up 51% versus US$451 million in the same quarter of 2004. o EBITDA (operating income plus depreciation and amortization) increased to US$1 billion, up 54% over the third quarter of 2004, mainly due to the acquisition of RMC. Hector Medina, Executive Vice President of Planning and Finance, said: "Our business showed continued strength in the third-quarter as we achieved significant increases in net sales and operating income. The results for the quarter reflect continued underlying growth in our core markets, as well as contributions from the recently integrated RMC operations. We are pleased to report the achievement of a 2.6 times net debt to EBITDA ratio only seven months after we completed the acquisition of RMC, one quarter ahead of schedule." Consolidated Corporate Results - ------------------------------ Cost of goods sold and selling, general, and administrative expenses (SG&A) increased 117% and 155%, respectively, versus the third quarter of 2004 due mainly to the acquisition of RMC. Majority net income for the third quarter of 2005 rose 87%, to US$675 million from US$361 million in third quarter of 2004, and has increased 99% during the first nine months of 2005, reaching US$1,855 million. Net debt at the end of the third quarter 2005 was US$8.9 billion, a reduction of US$724 million during the quarter. The net-debt-to-EBITDA ratio improved to 2.6 from 2.9 at the end of second quarter 2005. Interest coverage remained unchanged from second quarter 2005 at 6.5, decreasing from 6.7 one year prior. During the quarter, free cash flow of US$679 million plus US$91.5 million in proceeds from the additional assets contributed to the joint venture with Ready Mix USA were primarily used to reduce net debt by US$687 million (when expressed in US dollars, net debt was further reduced by US$37 million due mainly to the depreciation of the euro, British pound and yen versus the US dollar during the quarter), and for investments in connection with the post merger integration of RMC. Completion of Non-Dilutive Equity Offering - ------------------------------------------ On October 3, 2005, CEMEX announced that a total of 30,993,340 ADSs were sold in a non-dilutive equity offering, which included the sale of 27,000,000 ADSs, plus an additional 3,993,340 ADSs to cover over-allotments. The 30,993,340 ADSs were sold in the form of both ADSs and CPOs, comprised of 22,943,340 ADSs and 80,500,000 CPOs with one ADS representing ten CPOs. The ADSs were offered to the public at a price of US$49.50 per ADS, and the CPOs were offered to the public at a price of MXN53.89 per CPO. The aggregate proceeds of the offering, including proceeds from the exercise of the over-allotment option, were approximately US$1.5 billion, after underwriting discounts and commissions. Approximately US$1.3 billion of these proceeds were used to unwind all of the forward contracts entered into between CEMEX and certain banks, with the remaining approximately US$200 million paid to CEMEX on October 3, 2005. The transaction did not increase the number of shares outstanding. Joint Venture with Ready Mix USA - -------------------------------- On September 1, 2005, CEMEX announced the signing of an agreement to expand the scope of the recently formed joint venture with Ready Mix USA. As part of the expansion of the joint venture, CEMEX contributed 27 additional ready-mix plants and 4 additional block facilities that are located in the Atlanta, Georgia metropolitan area and operated under the Allied Ready Mix name. In return for the contribution of these assets CEMEX received from the joint venture a net amount of approximately US$91.5 million . Major Markets Third-Quarter Highlights - -------------------------------------- Net sales in CEMEX's Mexican operations increased 10% to US$782 million compared to US$709 million the same quarter of 2004 and EBITDA grew 2% over the prior year period to US$310 million. Cement volumes in Mexico increased 1% during the quarter versus the third quarter of 2004, while ready-mix volumes increased 14% over the same period. The main drivers of demand in the Mexican cement market continue to be in the residential construction and infrastructure sectors. In the United States, net sales for the quarter were US$1.2 billion, up 116% over the third quarter of 2004, while EBITDA increased 121% to US$329 million. U.S. operations cement volumes increased 2% versus the same period a year ago and ready-mix volumes increased 212% due in large part to the consolidation of RMC operations. Cement demand continues to be driven primarily by a strong infrastructure sector, particularly in street and highway construction, as well as a growing industrial and commercial sector and a healthy residential sector. CEMEX's operations in Spain reported net sales of US$376 million in the third quarter of 2005, up 19% versus the third quarter of 2004. EBITDA increased 10% to US$107 million in the quarter. Domestic cement volume decreased 2% over the third quarter 2004, ready-mix volume increased 59% over the previous year period. For the first nine months of the year, cement and ready-mix volumes increased 5% and 56%, respectively, versus the first nine months of 2004. In Spain, the main drivers of cement and ready-mix demand continue to be infrastructure spending and residential construction but growth has moderated versus the first half of the year. Net sales and EBITDA of the Company's operations in the United Kingdom were US$480 million and US$50 million respectively. Cement sales in the UK decreased 4% for the third quarter and ready-mix volumes decreased 3% versus the same periods in 2004. The public, residential, industrial and commercial sectors remain the primary growth drivers in the UK although they are growing slower due to reduced spending on infrastructure and decreased demand from the repair, maintenance and improvement sectors Other European Markets - ---------------------- During the third quarter of 2005, net sales in the other European markets was US$855 million and EBITDA was US$128 million. In France, ready-mix volumes increased 8% in the third quarter. The increase in ready-mix demand is mainly due to a strong housing sector, driven by low interest rates and tax incentives aimed at promoting housing construction. In Germany, the economic environment continues to be plagued with high unemployment, low consumer confidence and an overall weak business environment. Spending in infrastructure, which remains depressed due to high levels of public debt and limited investments, has offset the nonresidential sector, which has grown slightly due to a rise in commercial building construction. Cement sales volumes for the quarter declined 13% versus the comparable period of 2004. South/Central America and the Caribbean - --------------------------------------- CEMEX operations in South/Central America and the Caribbean reported net sales of US$358 million during the second quarter of 2005, an increase of 16% over the third quarter of 2004. EBITDA decreased 16% to US$103 million versus the prior year period. Domestic cement volumes in the region increased 16% in the quarter versus third quarter 2004. The Venezuelan economy continues to recover spurring construction spending. The main factors contributing to increased cement demand are the residential (both self-construction and government-sponsored housing) and infrastructure sectors fueled by increased oil revenues. For the quarter, cement volumes in Venezuela increased 38% versus third quarter 2004. In Colombia, cement volumes grew 30% during the quarter mainly due to high demand from the self-construction sector and infrastructure spending. Africa and Middle East - ---------------------- Third-quarter net sales in Africa and the Middle East were US$155, up 200% as compared to the same quarter of 2004. EBITDA increased 69% to US$43 million. Construction activity in the Middle East remains at a high level with housing requirements and oil revenues driving public and private investments. Asia - ---- Operations in Asia reported an increase in net sales of 53% over the third quarter of 2004, or US$76 million, while EBITDA was US$13 million, down 2% over the previous year period. Cement volumes in the region decreased 3% during the quarter.

During the quarter, free cash flow of US$679 million plus US$91 million in proceeds from the additional assets contributed to the joint venture with Ready Mix USA were primarily used to reduce net debt by US$687 million (when expressed in US dollars, net debt was further reduced by US$37 million due mainly to the depreciation of the euro, British pound and yen versus the US dollar during the quarter), and for investments in connection with the post merger integration of RMC.

(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, beginning this year, 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. - -------------------------------------------------------------------------------- Please refer to the end of this report for definitions of terms, US dollar translation methodology, and other important disclosures.

CEMEX Equity-Related Information ================================================================================ One CEMEX ADR represents ten CEMEX CPOs. The following amounts are expressed in CPO terms and reflect the 2 for 1 stock split effective July 1, 2005. Beginning-of-quarter CPO-equivalent units outstanding 3,518,706,245 - ------------------------------------------------------------------------------ Exercise of stock options not hedged 251,756 Less increase (decrease) in the number of CPOs held insubsidiaries (3,934,652) End-of-quarter CPO-equivalent units outstanding 3,522,892,653 - ------------------------------------------------------------------------------ Outstanding units equal total shares issued by CEMEX less shares held in subsidiaries. Employee long-term compensation plans (1) As of September 30, 2005, executives had outstanding options on a total of 60,593,200 CPOs, with a weighted average strike price of US$3.14 per CPO (equivalent to US$31.40 per ADR). The total amount of CPO-equivalent units outstanding increased 0.12% during the quarter as we sold shares in subsidiaries to cover the exercise of dilutive stock options. Starting in 2005, CEMEX began offering executives a stock-ownership program. The plan's goal is to move CEMEX's long-term incentives from stock options to programs based on restricted stock. As of September 30, 2005, our executives held 108,568,124 restricted CPOs, representing 3.08% 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. Third quarter (2) Second quarter ----------------- -------------- Notional amounts 2005 2004 2005 ================================================================================ Equity(1) 0 1,179 1,280 Foreign-exchange 4,106 5,953 3,643 Interest-rate 3,487 2,120 3,489 - -------------------------------------------------------------------------------- Estimated aggregate fair market value 304 (197) 149 ================================================================================ 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$304 million, arising from the fair market value recognition of its derivatives portfolio as of September 30, 2005. This net asset does not include the liability related to our stock-option programs of approximately US$208.8 million as of September 30, 2005 (see footnote #1 below). 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 non-dilutive equity offering and the liquidation of the equity forward contracts that hedged our executive options 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. As of September 30, 2005, CEMEX had accrued a liability of approximately US$208.8 million arising from the valuation of its stock options, of which approximately US$92.8 million correspond to the time value of the stock options. (2) Notional amounts and fair market values at the end of third quarter 2004 do not include the effect of the RMC acquisition. - -------------------------------------------------------------------------------- Please refer to the end of this report for definitions of terms, US dollar translation methodology, and other important disclosures.

CEMEX Other Activities ================================================================================ CEMEX completes non-dilutive equity offering On October 3, 2005, CEMEX announced that a total of 30,993,340 ADSs were sold in a non-dilutive equity offering, which includes the sale of 27,000,000 ADSs, plus an additional 3,993,340 ADSs to cover over-allotments. The underwriters fully exercised their option to purchase the additional ADSs to cover over-allotments. The 30,993,340 ADSs were sold in the form of both ADSs and CPOs, comprised of 22,943,340 ADSs and 80,500,000 CPOs. One ADS represents ten CPOs. The ADSs were offered to the public at a price of US$49.50 per ADS, and the CPOs were offered to the public at a price of MXN53.89 per CPO. The aggregate proceeds of the offering, including proceeds from the exercise of the over-allotment option, were approximately US$1.5 billion, after underwriting discounts and commissions. Approximately US$1.3 billion of these proceeds were used to unwind all of the forward contracts entered into between CEMEX and certain banks, with the remaining approximately US$200 million paid to CEMEX on October 3, 2005. This transaction did not increase the number of shares outstanding and thus did not dilute the equity of existing shareholders. CEMEX contributes additional assets to joint venture with Ready Mix USA. On September 1, 2005, CEMEX announced the signing of an agreement to expand the scope of the recently formed joint venture with Ready Mix USA. Under the initial arrangement that was completed on July 1, 2005, CEMEX Inc. contributed to the joint venture two cement plants (Demopolis, Alabama and Clinchfield, Georgia), eleven cement terminals, and its ready-mix aggregates and block assets in the Florida Panhandle and Southern Georgia. Ready Mix USA contributed all of its ready-mix and aggregates operations in Alabama, Georgia, the Florida Panhandle, and Tennessee, as well as its block operations in Arkansas, Tennessee, Mississippi, Florida, and Alabama. The cement assets of the joint venture are being managed by CEMEX, and the ready-mix, aggregates and block assets are being managed by Ready Mix USA. As a part of the expansion of the joint venture, CEMEX contributed 27 additional ready-mix plants and 4 additional block facilities, all of which are located in the Atlanta, Georgia metropolitan area and were operating under the Allied Ready Mix name. In return for the contribution of these additional assets, CEMEX received from the joint venture approximately US$91.5 million. Ready Mix USA will manage these newly contributed assets. - -------------------------------------------------------------------------------- Please refer to the end of this report for definitions of terms, US dollar translation methodology, and other important disclosures.

CEMEX Operating Results ================================================================================ Mexico Our Mexican operations' cement volumes increased 1% during the quarter versus third quarter 2004, while ready-mix volumes increased 14% over the same period. For the first nine months of the year, cement volumes decreased 1% versus the same period in 2004, while ready-mix volumes increased 15% over the same period. Cement prices were 8% 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 nine months of 2004. Ready-mix prices, in US-dollar terms, were 5% higher during the first nine months of the year versus the same period in 2004. The main drivers of demand during the year have been government infrastructure spending and residential construction, the latter supported by increased credit availability from commercial banks, and non-commercial sources such as INFONAVIT. Cement demand from the self-construction sector remains weak, despite increased disposable income, primarily because the formal sector has attracted customers through increased financing availability. United States In CEMEX's US operations, cement volumes increased 2% in third quarter 2005 versus the same period a year ago. For the first nine months of the year, cement volumes increased 5%. On a like-to-like basis for the ongoing operations, cement volumes increased 7% both for the quarter and for the first nine months of the year versus the comparable periods of last year. Ready-mix volumes increased 212% during the quarter and 175% for the first nine months of the year due to the consolidation of RMC operations. On a like-to-like basis for the ongoing operations, ready-mix volumes for the quarter and first nine months of the year increased 7% and 5%, respectively, versus the same periods of last year. Aggregates volume, on a like-to-like basis for the ongoing operations, increased 6% and 12% for the third quarter and first nine months of the year, respectively, over last year's periods. Cement prices have increased 18% for the first nine months of the year, while ready-mix prices increased 26% during the same period. Aggregates prices have increased 19% year to date versus the same period last year. Construction spending for the first eight months of the year is up 9% versus last year's period. Cement demand continues to be driven mainly by a strong infrastructure sector, particularly streets and highway construction; a growing industrial and commercial sector, with construction spending up 7% for the first eight months of the year; and a healthy residential sector, with construction spending up 11% for the first eight months of the year. Spain Domestic cement volume decreased 2% over that of third quarter 2004 while ready-mix volume increased 59%. For the first nine months of the year, cement and ready-mix volumes increased 5% and 56%, respectively, versus the first nine months of 2004. The main drivers of cement and ready-mix demand continue to be infrastructure spending and residential construction, with housing starts up 4% for the first seven months of the year. Although the residential sector remains at record high levels of construction, it has moderated its growth rate versus that seen in the first half of the year. Prices in US dollars for domestic cement increased 7% and 9% for third quarter and first nine months of the year, respectively, versus the comparable periods in 2004. United Kingdom Cement sales volumes in the UK decreased 4% for the third quarter and decreased 2% for the first nine months of the year versus the comparable periods in 2004. Ready-mix volumes decreased 3% and 1% for the quarter and the first nine months of the year, respectively, versus the same periods in 2004. Cement and ready-mix prices increased 8% and 5%, respectively, in dollar terms during the first nine months of the year versus the same period in 2004, offsetting higher fuel and electricity costs. The UK economy has weakened during the past months, which in turn has lowered cement and ready-mix consumption. The decline in national consumption of cement and ready mix is due mostly to decreased demand from the repair, maintenance, and improvement sector, as well as lower spending in infrastructure. Although growing at a lower pace from last year, the public, residential, and industrial and commercial sectors remain the primary drivers of growth. - -------------------------------------------------------------------------------- Please refer to the end of this report for definitions of terms, US dollar translation methodology, and other important disclosures.

CEMEX Operating Results ================================================================================ Rest of Europe In France, ready-mix volumes increased 8% in the third quarter and 5% during the first nine months of the year versus the same periods of 2004. Aggregates volumes decreased 1% in third quarter and remained flat year to date. Prices of ready-mix in US dollars increased 6% during the first nine months of the year versus the same period in 2004. The increase in ready-mix demand is mainly due to a strong housing sector, which is expected to reach a 20-year high this year, driven by low interest rates and tax incentives aimed at promoting housing construction. In Germany, the economic environment remains unfavorable, with high unemployment, low consumer confidence, and an overall weak business climate. The public works sector, which remains depressed due to high public debt and limited investments, has offset the nonresidential sector, which has grown slightly due to a rise in commercial building construction. Cement sales volumes for the quarter and for the first nine months of the year declined 13% and 16%, respectively, versus the comparable periods of 2004. Ready-mix volumes in Germany have declined 13% during the first nine months of the year versus the same period of 2004. Cement prices in Germany have increased 27% in US dollars for the first nine months of the year versus the same period in 2004. For the rest of our portfolio in Europe, aggregate domestic cement volume has increased 3% and ready-mix volumes have decreased 1% for the first nine months of the year versus the comparable period of 2004. Weighted-average cement and ready-mix prices in US dollars have both increased 10% year to date versus the same period last year. South/Central America and Caribbean Domestic cement volumes in the region increased 16% in the quarter and 14% during the first nine months of the year versus the same periods of last year. The Venezuelan economy continues to recover, and with it construction spending. The main sectors contributing to increased cement demand are the infrastructure - - fueled by increased oil revenues - and residential (both self-construction and government-sponsored housing) sectors. For the quarter, cement volumes in Venezuela increased 38% versus third quarter 2004. In Colombia, cement volumes grew 30% during the quarter due mainly to high demand from the self-construction sector, as unemployment has declined and wages have increased. Infrastructure spending has also been a significant contributor to cement demand. Africa and Middle East Construction activity in the Middle East is currently running at a high level, with increased housing requirements and oil revenues driving public and private investments. Our operations in Egypt have increased their cement volumes throughout the year supported mainly by a strong infrastructure sector driven by private investment, and healthy residential and self-construction sectors. Overall, the region's domestic cement volumes during the quarter increased 33% versus the same period in 2004, while average prices in US-dollar terms increased 20%. Asia In aggregate, our cement volumes in the region decreased 3% during the quarter and increased 2% for the first nine months of the year, versus the same periods of last year. Cement demand in the Philippines declined during the quarter due to lower public and private spending related to the political uncertainty in the country, as well as the scarcity of government resources to fund infrastructure projects. In Thailand, the volume of cement sold decreased versus last year's level due to intensified competition in the country, while cement volumes in Bangladesh increased significantly during the quarter due to the expansion of the markets covered by our operations in that country. Average cement prices in the region increased 9% in US dollars during the third quarter versus the same period in 2004. - -------------------------------------------------------------------------------- Please refer to the end of this report for definitions of terms, US dollar translation methodology, and other important disclosures.

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, 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 third quarter 2005, second quarter 2005, and third quarter 2004 are 10.76, 10.75, and 11.38 Mexican pesos per US dollar, respectively. CEMEX's weighted-average inflation factor between September 30, 2004, and September 30, 2005, was -1.29%. 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 September 30, 2005, and September 30, 2004, can be converted into their original local currency amount by multiplying the US-dollar figure by the corresponding exchange rate provided below. To convert September 30, 2004, US-dollar figures for Mexico to constant Mexican pesos as of September 30, 2005, it is necessary to first convert the September 30, 2004, US-dollar figure to Mexican pesos using the exchange rate provided below, and then multiply the resulting amount by 1.0362, the inflation-rate factor between September 30, 2004, and September 30, 2005. September 30 ---------------------------- Exchange rate 2005 2004 - ---------------------------------------------------- Mexican Peso 10.76 11.38 Euro 0.83 0.80 British Pound 0.57 0.55 - ---------------------------------------------------- Amounts provided in units of local currency per US dollar. Breakdown of regions The South/Central America and Caribbean region includes CEMEX's operations in Argentina, Colombia, Costa Rica, the Dominican Republic, Jamaica, Nicaragua, Panama, Puerto Rico, and Venezuela, as well as our trading operations in the Caribbean region. Rest of Europe includes operations in Austria, Croatia, Czech Republic, Denmark, Finland, France, Germany, Hungary, Ireland, Latvia, Lithuania, Norway, Poland, Portugal, and Sweden. Africa and Middle East includes operations in Egypt, Israel, and the United Arab Emirates. The Asia region includes operations in Bangladesh, Malaysia, the Philippines, Taiwan, and Thailand. 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, 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). Capital expenditures consist of maintenance and 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. This ratio includes CEMEX's EBITDA for the last twelve months plus the estimated EBITDA of RMC for the last twelve months (please refer to footnote 2 on the second page of this report for further details). Earnings per ADR The number of average ADRs outstanding used for the calculation of earnings per ADR was 352.1 million for the third quarter 2005 and 343.8 million for the first nine months of 2005, 339.0 million for third quarter 2004 and 330.8 million for the first nine months of 2004. - -------------------------------------------------------------------------------- Please refer to the end of this report for definitions of terms, US dollar translation methodology, and other important disclosures.

CEMEX Definition of Terms and Disclosures ================================================================================ Effect of the purchase of RMC on our financial statements The acquisition of RMC was concluded on March 1, 2005. The processes to allocate the purchase price paid for RMC's shares of approximately US$4.1 billion, not including other direct purchase costs, to the fair values of the assets acquired and liabilities assumed, substantially began during March 2005 concurrent with the assumption of control by CEMEX; consequently, as of September 30, 2005, CEMEX is in a preliminary stage in terms of determining the fair values of the net assets of RMC, including acquired intangible assets. Therefore, as of September 30, 2005, the difference between the purchase price paid and the book value of RMC as of March 1, 2005, was fully allocated to goodwill for an amount of approximately U.S.$2.2 billion. In subsequent periods, as we move forward in our determination of the fair values of RMC's assets and liabilities, the amount of initial goodwill will be adjusted against the corresponding balance-sheet accounts. Under Mexican GAAP, entities have up to a one-year period after the purchase to conclude the purchase-price allocation. - -------------------------------------------------------------------------------- Please refer to the end of this report for definitions of terms, US dollar translation methodology, and other important disclosures.
