The accompanying notes are an integral part of the consolidated financial statements.

A.Basis of Presentation -The Condensed Consolidated Financial Statements are unaudited. These statements include all adjustments, consisting of only normal recurring adjustments, considered necessary by management to fairly present the results of operations, financial position, and cash flows. The results reported in these Condensed Consolidated Financial Statements are not necessarily indicative of the results that may be expected for the entire year.

This Form 10-Q report should be read in conjunction with Alcoa’s annual report on Form 10-K for the year ended December 31, 2003, which includes all disclosures required by accounting principles generally accepted in the United States of America.

B.Debt – In June 2004, Alcoa recognized a net gain of $58 in other income on the early retirement of long-term debt and the associated settlement of interest rate swaps. Alcoa retired $1,200 of debt securities, consisting of the following: $200 of 6.125% Bonds due in 2005, $500 of 7.25% Notes due in 2005, and $500 of 5.875% Notes due in 2006. These debt securities were retired primarily with proceeds from commercial paper borrowings. The net gain of $58 is comprised of the following:

Alcoa previously used interest rate swaps to establish fixed interest rates on anticipated borrowings between June 2005 and June 2006. Due to a change in forecasted borrowing requirements, resulting from the early retirement of debt in June 2004 and a forecasted increase in future operating cash flows resulting from improved market conditions, the anticipated borrowings are no longer probable of occurring in 2005 and 2006. Therefore, Alcoa recognized $33 of gains that had been deferred on previously settled swaps and $44 of cash proceeds which was recorded as a gain to unwind the remaining interest rate swaps.

In connection with this transaction, Alcoa terminated $1,000 notional value of interest rate swaps that resulted in a cash payment by Alcoa of $32. These interest rate swaps were hedging debt maturing in 2007 and 2011. The $32 is reflected as a reduction in the carrying value of debt and it will be recognized as an increase in interest expense over the remaining maturity of the related hedged debt.

C.Stock-Based Compensation – Stock options under the company’s stock incentive plans have been granted at not less than market prices on the dates of grant. Stock option features based on date of original grant are as follows:

Alcoa accounts for stock-based compensation in accordance with the provisions of Accounting Principles Board Opinion No. 25, “Accounting for Stock Issued to Employees,” and related interpretations using the intrinsic value method, which resulted in no compensation cost for options granted.

Alcoa’s net income and earnings per share would have been reduced to the pro forma amounts shown below if compensation cost had been determined based on the fair value at the grant dates in accordance with Statement of Financial Accounting Standards (SFAS) Nos. 123 and 148, “Accounting for Stock-Based Compensation.”

In addition to stock option awards described above, beginning in 2004 the company granted stock awards and performance share awards that vest in three years from the date of grant. Compensation expense of $9 (pre-tax) was recognized on these awards in the first ~~quarter~~half of ~~2004 and was not material.~~2004.

C.D. Pension Plans and Other Postretirement Benefits – Effective December 31, 2003, Alcoa adopted SFAS No. 132 (revised 2003), “Employers’ Disclosures about Pensions and Other Postretirement Benefits.” This standard requires the disclosure of the components of net periodic benefit cost recognized during interim periods.

The ~~first quarter 2004~~ net periodic benefit cost for postretirement benefits for the three-month and six-month periods ended June 30, 2004 reflects a reduction of approximately $6 and $12, respectively, related to the recognition of the federal subsidy under Medicare Part D. For further details on the Medicare Part D subsidy, see Note V to the audited financial statements contained in the Annual Report on Form 10-K for the year ended December 31, 2003.

D.E. Discontinued Operations and Assets Held for Sale –In the fourth quarter of 2002, Alcoa performed a portfolio review of its businesses and the markets they serve. As a result of this review, Alcoa committed to a plan to divest certain noncore businesses that did not meet internal growth and return measures. A detailed discussion of Alcoa’s 2002 divestiture plan and changes to the plan in 2003 can be found in Note B to the audited financial statements contained in Alcoa’s Annual Report on Form 10-K for the year ended December 31, 2003. ~~This disclosure provides information~~Information on divestiture activities that occurred in the first ~~quarter~~half of ~~2004.~~2004 is provided below.

For the periods presented in the Condensed Consolidated Financial Statements, businesses classified as discontinued operations included Alcoa’s commodity automotive fasteners business, a packaging business in South America, and Alcoa’s packaging equipment business. In January of 2004, Alcoa sold its packaging equipment business to American Industrial Partners for $44 in cash and recognized

a gain of $10. In February of 2004, Alcoa sold its automotive fasteners business to the Kaminski Holdings group for $17 in cash and notes receivable and recognized an additional loss of $5. The gain and loss from these transactions are recorded in Income from Discontinued Operations in the income statement. In July of 2004, Alcoa sold its flexible packaging business in South America.

The following table details selected financial information for the businesses included within discontinued operations.

For the periods presented in the Condensed Consolidated Financial Statements, businesses classified as assets held for sale included Alcoa’s specialty chemicals business, ~~certain architectural products businesses in North America,~~ an extrusion facility in Europe, certain extrusion facilities in Latin America, and foil facilities in St. Louis, MO and Russellville, AR. In February of 2004, the specialty chemicals business of Alcoa was sold to two private equity firms led by Rhone Capital LLC for an enterprise value of $342, which included the assumption of debt and other unfunded obligations. Alcoa received cash of $248 and recognized a pre-tax, pre-minority interest gain of approximately ~~$44~~$49 ($5859 after-tax, after-minority interest). The gain is included in Restructuring and Other Charges in the income statement.

In April of 2004, Alcoa sold its St. Louis, MO and Russellville, AR foil facilities, as well as an extrusion facility in Europe. Alcoa received $37 in cash and no material gain or loss was recorded on these transactions.

The major classes of assets and liabilities of operations held for sale in the balance sheet are as follows:

The changes in assets and liabilities of operations held for sale at ~~March 31,~~June 30, 2004 compared with December 31, 2003 are due to the divestitures of Alcoa’s packaging equipment, automotive fasteners, and specialty chemicals businesses, ~~during~~as well as the ~~first quarter~~sale of the St. Louis and Russellville foil facilities and an extrusion plant in Europe in 2004. The divestiture program is essentially complete, with the exception of certain Latin American extrusion facilities that remain in assets held for sale.

E.F. Restructuring and Other Charges – In the first half of 2004, Alcoa recorded income of $26 for restructuring and other charges, consisting of income of $31 in the first quarter and expense of $5 in the second quarter. In the second quarter of 2004, Alcoa recorded restructuring and other charges of

$5 ($4 after tax and minority interests), consisting of charges of $14 for employee termination and severance costs associated with 2,700 salaried and hourly employees (primarily in Mexico and the U.S.), as the company continued to focus on reducing costs, partially offset by income of $6 associated with net gains on divested businesses and asset sales, and income of $3 resulting from adjustments to prior year employee termination and severance cost reserves. As of June 30, 2004, 1,660 of the 2,700 employees had been terminated. In the first quarter of 2004, Alcoa recorded income of $31 ($50 after tax and minority interests) for restructurings, consisting of a $44 gain on the sale of the specialty chemicals business ~~of $44~~ and charges of $13 for employee termination and severance costs associated with 380 salaried and hourly employees (primarily in the U.S. and U.K.)~~, as the company continued to focus on reducing costs.~~. As of ~~March 31,~~June 30, 2004, ~~210~~250 of the 380 employees had been ~~terminated and approximately $6~~terminated. Approximately $12 of cash payments were made against the ~~reserves.~~reserves in the first half of 2004. All layoffs are expected to be completed in 2004. Restructuring and other charges are not reflected in the segment results.

During 2003, Alcoa recorded income of $26 ($25 after tax and minority interests) for restructuring and other charges. The income recognized was comprised of the following components: $45 of charges for employee termination and severance costs associated with approximately 1,600 hourly and salaried employees (located primarily in Europe, the U.S., and Brazil), as the company continued to focus on cost reductions in businesses that continued to be impacted by market declines; $20 of charges related to a reduction in the estimated fair values of businesses included in assets held for sale; and $91 of income comprised of $53 primarily associated with the sale of the Latin America PET business, and $38 resulting from adjustments to prior year employee termination and severance cost reserves (in conjunction with the $38 reserve adjustment, there was a change in the number of employees to be terminated under the 2002 restructuring program from 8,500 to 6,700 employees). As of ~~March 31,~~June 30, 2004, approximately ~~1,270~~1,530 of the 1,600 employees associated with the 2003 restructuring program had been terminated.

During 2002, Alcoa recorded charges of $425 ($280 after tax and minority interests) for restructurings associated with the curtailment of aluminum production at three smelters, as well as restructuring operations for those businesses experiencing negligible growth due to continued market declines and the decision to divest certain businesses that have failed to meet internal growth and return measures. The 2002 charges were comprised of $296 for asset write-downs, consisting of $113 of goodwill on businesses to be divested, as well as $183 for structures, machinery, and equipment; $105 for employee termination and severance costs related to approximately 6,700 hourly and salaried employees at over 70 locations, primarily in Mexico, Europe, and the U.S.; and charges of $31 for exit costs, ~~primarily~~principally for remediation and demolition costs, as well as lease termination costs. As of ~~March 31,~~June 30, 2004, approximately ~~6,450~~6,490 of the 6,700 employees associated with the 2002 restructuring program had been terminated.

Approximately 45% of total inventories at ~~March 31,~~June 30, 2004, was valued on a LIFO basis. If valued on an average cost basis, total inventories would have been ~~$556~~$585 and $558 higher at ~~March 31,~~June 30, 2004 and December 31, 2003, respectively.

G.H. Commitments and Contingencies- Various lawsuits, claims and proceedings have been or may be instituted or asserted against Alcoa, including those pertaining to environmental, product liability, and safety and health matters. While the amounts claimed may be substantial, the ultimate liability cannot now be determined because of the considerable uncertainties that exist. Therefore, it is possible that results of operations or liquidity in a particular period could be materially affected by certain contingencies. However, based on facts currently available, management believes that the disposition of matters that are pending or asserted will not have a materially adverse effect on the financial position of the company.

Alcoa Aluminio S.A. (Aluminio) is a participant in several hydroelectric power construction projects in Brazil for purposes of increasing its energy self-sufficiency and providing a long-term, low-cost source of power for its facilities.

The completed and committed hydroelectric construction projects that Aluminio participates in are outlined in the following tables.


Completed projects	Date completed	Investment participation		Share of output		Debt guarantee		Debt guarantee through 2013		Date completed	Investment participation		Share of output		Debt guarantee		Debt guarantee through 2013
Machadinho	2002	27.23	%	22.62	%	35.53	%	$	106	2002	27.23	%	22.62	%	35.53	%	$	106

Aluminio committed to taking a share of the output of the completed Machadinho project for 30 years at cost (including cost of financing the project). In the event that other participants in this project fail to fulfill their financial responsibilities, Aluminio may be required to fund a portion of the deficiency. In accordance with the agreement, if Aluminio funds any such deficiency, its participation and share of the output from the project will increase proportionately.

These projects were committed to during 2001 and 2002, and the Barra Grande project commenced construction in 2002. As of the ~~first~~second quarter of 2004, approximately 30% of the long-term financing for the Barra Grande project was obtained, of which Aluminio guaranteed 42.20% based on its investment participation. The plans for financing the other projects have not yet been finalized. It is anticipated that a portion of the project costs will be financed with third parties. Aluminio may be required to provide guarantees of project financing or commit to additional investments as these projects progress.

During 2003, the participants in the Santa Isabel project formally requested the return of the performance bond related to the license to construct the hydroelectric project. This project has been terminated.

Aluminio accounts for the Machadinho and Barra Grande hydroelectric projects on the equity method. Its total investment in these projects was ~~$142~~$111 and $136 at ~~March 31,~~June 30, 2004 and December 31, 2003, respectively. There have been no significant investments made in any of the other projects.

Other ~~expense~~income (expense) for the 2004 six-month period included a charge of $20 recognized in the first quarter of 2004 ~~includes a charge of $20~~ related to ~~tentative~~ settlements reached in the El Campo litigation matter. ~~For additional information, see Part II, Item 1 of this Form 10-Q.~~

K.L. Income Taxes – The effective tax rate of ~~27.9%~~28.6% for the 2004 ~~first quarter~~six-month period differs from the statutory rate of 35% and the 2003 ~~first quarter~~six-month rate of ~~29.8% primarily~~27.7% principally due to the sale of the specialty chemicals business in 2004 and lower taxes on foreign income.

L.M. Cumulative Effect of Accounting Change – Effective January 1, 2003, Alcoa adopted SFAS No. 143, “Accounting for Asset Retirement Obligations.” Under this standard, Alcoa recognized additional liabilities for asset retirement obligations (AROs), consisting primarily of costs associated with spent pot lining disposal, bauxite residue disposal, mine reclamation, and landfills. These costs reflect the legal obligations associated with the normal operation of Alcoa’s bauxite mining, alumina refining, and aluminum smelting facilities. There were no material changes to the ARO balances during the ~~first~~second quarter of 2004. Additionally, Alcoa capitalized asset retirement costs by increasing the carrying amount of related long-lived assets, ~~primarily~~principally machinery and equipment, and recorded associated accumulated depreciation from the time the original assets were placed into service. The cumulative effect adjustment recognized upon adoption of this standard was $47, consisting ~~primarily~~principally of costs to establish assets and liabilities related to spent pot lining for pots currently in operation.

Consolidated net income	$	355		$	151			$	404		$	216		$	759		$	367

The significant changes in the reconciling items between ATOI and consolidated net income for the 2004 second quarter and six-month period compared with the corresponding 2003 periods consisted of:

Additionally, corporate expense decreased in the second quarter of 2004 due to a decrease in deferred compensation costs.

The increase in segment assets within the Flat-Rolled Products segment is due to higher customer receivables and increased inventories resulting from stronger volumes and prices in 2004.

~~N .~~O. Reclassifications - Certain amounts have been reclassified to conform to current year presentation.

11P. Subsequent Event - On July 26, 2004, Alcoa announced that 400 employees at its Wenatchee, WA smelter will lose their jobs as a result of the rejection of a proposed labor contract by the Aluminum Trade Council of Wenatchee. The impact of the layoff is expected to result in an after-tax charge of approximately $13 in the third quarter of 2004. The Wenatchee facility has been idled since July of 2001.

We have reviewed the accompanying unaudited condensed consolidated balance sheet of Alcoa and its subsidiaries (Alcoa) as of ~~March 31,~~June 30, 2004, and the related unaudited condensed statements of consolidated income for each of the three-month and six-month periods ended June 30, 2004 and 2003, and the unaudited condensed statement of consolidated cash flows for the ~~three-month~~six-month periods ended ~~March 31,~~June 30, 2004 and 2003. These interim financial statements are the responsibility of Alcoa’s management.

We conducted our review in accordance with the standards ~~established by~~of the ~~American Institute of Certified~~ Public ~~Accountants.~~Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with ~~generally accepted auditing~~the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying unaudited condensed consolidated interim financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

We previously audited in accordance with ~~auditing~~the standards ~~generally accepted in~~of the ~~United States of America,~~Public Company Accounting Oversight Board (United States), the consolidated balance sheet ~~of Alcoa~~ as of December 31, 2003, and the related statements of consolidated income, shareholders’ equity and of cash flows for the year then ended (not presented herein), and in our report dated January 8, 2004, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying condensed consolidated balance sheet as of December 31, 2003 is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived.

As discussed in Note LM to the unaudited condensed consolidated financial statements, Alcoa changed its method of accounting for asset retirement obligations effective January 1, 2003.

Alcoa’s income from continuing operations infor the 2004 ~~first~~second quarter and six-month period of 2004 was ~~$350,~~$404, or 4046 cents per diluted share, ~~an increase of 79% over 2003 first quarter income of $195,~~and $754, or 2386 cents per ~~share. An increase in realized prices drove profitability~~share, respectively. Income from continuing operations increased 86% and 83% in the 2004 ~~first~~second quarter and six-month period, as compared to the corresponding 2003 periods. Results in 2004 were favorably impacted by higher realized prices, as alumina prices rose 33% and 28% and aluminum prices climbed 25% and 20% in the 2004 second quarter and six-month period, respectively, compared with the corresponding 2003 ~~first quarter, as prices for alumina and aluminum rose 18% and 14%, respectively.~~periods. The 2004 results were also favorably impacted by higher volumes in the ~~Primary Metals,~~Engineered Products and Flat-Rolled Products segments, as demand in the commercial transportation, building and ~~Engineered Products segments, ongoing~~construction, aerospace, packaging, and industrial markets improved; continued cost ~~reductions throughout~~reductions; and benefits from the ~~company,~~restructuring of debt, which consisted of the early repayment of debt and asettlement of interest rate swaps. The 2004 six-month period was also favorably impacted by the gain on the ~~sale of the~~ specialty chemicals ~~business. Partially offsetting these~~business that was sold in the first quarter of 2004. These positive contributions were partially offset by higher energy costs, the impact of ~~the weakened~~a weaker U.S. dollar against other currencies, increased environmental reserves, and higher raw material costs. The 2004 six-month period was also unfavorably impacted by litigation settlements ~~lower equity earnings, and restructuring charges primarily for employee layoffs.~~

Net income for the 2004 second quarter and six-month period was ~~$355,~~$404, or 4146 cents per share, ~~compared with net income of $151,~~and $759, or 1787 cents per share, respectively, as compared to $216, or 26 cents per share, and $367, or 43 cents per share, for corresponding periods in ~~the 2003 first quarter.~~2003. The 2003 results included a cumulative effect charge of $47, or 6 cents per share, for the accounting change for asset retirement obligations under Statement of Financial Accounting Standards (SFAS) No. 143, “Accounting for Asset Retirement Obligations.”

Sales for the ~~first~~2004 second quarter ~~of 2004 were $5,696, an increase of $556,~~and six-month period increased $595, or 11%, ~~over~~and $1,151, or 11%, respectively compared with corresponding 2003 ~~first quarter sales of $5,140.~~periods. The increase in realized prices for alumina and aluminum, as well as higher volumes in businesses serving the ~~primary metals,~~ packaging, ~~(can sheet),~~ aerospace, building and construction, ~~and~~ commercial transportation, and industrial markets ~~accounted for approximately two-thirds of~~helped to drive the increase in sales. The rise in sales was also aided by the favorable impact of foreign currency exchange movements and the consolidation of KAAL Australia (Alcoa acquired the remaining 50% interest from Kobe Steel Ltd. in October 2003.). Partially offsetting these increases ~~was a decline in third-party volumes for alumina due to higher internal demand, lower volumes for AFL automotive, and~~were the impact of divestitures, ~~primarily~~principally the specialty chemicals ~~business~~ and Latin American PET businesses, and lower volumes in the ~~Latin America PET~~AFL automotive business.

Cost of goods sold (COGS) as a percentage of sales was ~~77.9% in~~78.9% for the ~~first~~2004 second quarter ofand 78.4% for the 2004 six-month period, compared with 79.7% ~~for the~~in both 2003 ~~first quarter. Higher~~corresponding periods. The decreases resulted from higher realized prices and accumulated cost savings

resulting from procurement savings, productivity improvements, and headcount reductions from prior restructuring ~~programs,~~programs. These positive contributions more than offset higher raw material costs, increased energy costs, an increase of $42 in environmental reserves, and the unfavorable impact of foreign currency exchange movements.

Selling, general administrative, and other expenses (SG&A) ~~were $344,~~for the 2004 second quarter decreased $28, or ~~6.0% of sales, in 2004~~8%, compared with ~~$297, or 5.8% of sales, in 2003. The increase of $47, or 0.2% as a percentage of sales, was primarily~~the 2003 second quarter due to ~~higher bad debt expense related to an alumina customer bankruptcy,~~a reduction in deferred compensation costs and cost savings, which were partially offset by the unfavorable impact of foreign currency exchange movements. SG&A expenses increased $19, or 3%, in the 2004 six-month period compared to the 2003 corresponding period due to unfavorable foreign currency exchange movements, expense associated with stock awards granted in 2004, and ~~increased~~the bankruptcy of an alumina customer, which were partially offset by a reduction in deferred compensation ~~and employee benefit~~ costs.

The provision for depreciation, depletion, and amortization was ~~$303~~relatively flat in the 2004 second quarter as compared ~~with $285~~to the second quarter of 2003. The provision increased by $17, or 3%, in the 2004 six-month period over the corresponding 2003 ~~an increase of $18, or 6%. The increase was~~period primarily due to unfavorable foreign currency exchange movements.

Restructuring and other charges resulted in expense of $5 in the 2004 second quarter and income of $26 in the 2004 six-month period, compared with an expense of $3 in the second quarter of 2003 and income of $1 in the 2003 six-month period. In the second quarter of 2004, a charge of $14 was recorded for employee termination and severance costs associated with 2,700 salaried and hourly employees (primarily in Mexico and the U.S.). Partially offsetting this charge were income of $6 associated with net gains on divested businesses and asset sales, and income of $3 resulting from adjustments to prior year employee termination and severance cost reserves. As of June 30, 2004, 1,660 of the 2,700 employees had been terminated. In the first quarter of 2004, income of $31 ~~in 2004 compared with income of $4 in 2003. The income recognized in 2004~~ was ~~comprised~~recorded for restructuring and other charges, consisting of a gain of $44 on the sale of the specialty chemicals business, which was somewhat offset by ~~restructuring~~ charges of $13 for employee termination and severance costs associated with 380 salaried and hourly employees (primarily in the U.S. and U.K.)~~, as the company continued to focus on reducing costs.~~. As of ~~March 31,~~June 30, 2004, ~~210~~250 of the 380 employees had been ~~terminated and approximately $6~~terminated.

Third-party sales for the Primary Metals segment increased 19% in the second quarter of 2004 and 20% in the ~~first~~2004 six-month period, compared with the corresponding periods of 2003, due to 25% higher realized prices in the second quarter of 2004 ~~compared with the first quarter of 2003 primarily due to 14%~~and 20% higher realized prices ~~as well as higher~~for the 2004 six-month period, partially offset by lower third-party volumes. Intersegment sales increased ~~24%~~64% in the second quarter of 2004 and 42% in the 2004 six-month period primarily due to the increase in realized prices as well as increased volumes due to strengthening in the downstream aluminum businesses.

ATOI for this segment increased ~~16%~~42% in the 2004 second quarter and 29% in the 2004 six-month period due to higher realized prices and higher total volumes, somewhat offset by higher costs for energy, raw materials, ~~and~~ employee benefits, and the impact of unfavorable foreign currency exchange movements.

ATOI for this group increased 76% in the 2004 second quarter and 85% in the 2004 six-month period, compared to corresponding 2003 periods, due to increased volumes in the residential building products business ~~attributed to better weather conditions,~~ and ~~higher volumes in~~ the telecommunications business, ~~and the automotive parts business.~~

~~ATOI for this group doubled from the prior year quarter primarily due to increased volumes and~~ cost savings, ~~in the telecommunications~~ and ~~the automotive parts businesses, as well as~~ higher equity income from Integris Metals, Inc.

The significant changes in the reconciling items between ATOI and consolidated net income for the 2004 ~~first~~second quarter and six-month period compared with the corresponding 2003 ~~first quarter~~periods consisted of of:

Additionally, corporate expense decreased in the second quarter of 2004 due to a decrease in deferred compensation costs.

Cash from operations was ~~$70~~$560 in the ~~first quarter of~~ 2004 six-month period compared with ~~$(33)~~$1,215 in the ~~first quarter~~same period of 2003. The ~~increase~~decrease of ~~$103~~$655 is ~~primarily~~principally due to ~~higher earnings after adjustments for noncash items.~~net increases in inventories, receivables, and payables of $426 and the absence of a $440 advance payment received in 2003 against a long-term aluminum supply contract, partially offset by the increase in net income.

Cash used for financing activities was ~~$258~~$562 in the 2004 ~~first quarter~~six-month period compared with cash ~~provided~~used of ~~$189~~$764 in the 2003 ~~first quarter.~~six-month period. The change of ~~$447~~$202 is primarily due to ~~the repurchase of common stock as well as~~higher net debt repayments in 2003 than in 2004.

In June 2004, Alcoa completed the early retirement of ~~$68~~$1,200 of debt securities, consisting of the following: $200 of 6.125% Bonds due in ~~2004 compared with net borrowings~~2005, $500 of ~~$357~~7.25% Notes due in ~~2003. Debt repayments~~2005, and $500 of 5.875% Notes due in ~~2004~~2006.

On April 23, 2004 Alcoa ~~will refinance~~refinanced its $2,000 revolving-credit agreement that was to expire in April 2004 into a new $1,000 revolving-credit agreement that will expire in April 2005, with an option to extend the maturity date of any borrowings outstanding on the April 2005 expiration date for one year. Additionally, Alcoa ~~will refinance~~refinanced its $1,000 revolving-credit agreement that was to expire in April 2005 into a new agreement that will expire in April 2009.

Cash ~~provided from~~used for investing activities was ~~$71~~$106 in the 2004 ~~first quarter~~six-month period compared with ~~cash used of $138~~$379 in the ~~2003 first quarter.~~same period in 2003. The change of ~~$209~~$273 was primarily due to proceeds received from the divestitures of Alcoa’s specialty chemicals, packaging equipment, and automotive fasteners businesses, as well as foil facilities, and a European extrusion facility. This was somewhat offset by cash used to acquire 44 million additional shares of Chalco to maintain Alcoa’s 8% ownership interest.

Alcoa continues to participate in environmental assessments and cleanups at a number of locations. These include approximately 30 owned or operating facilities and adjoining properties, approximately 39 previously owned or operating facilities and adjoining properties and approximately 67 Superfund and other waste sites. A liability is recorded for environmental remediation costs or damages when a cleanup program becomes probable and the costs or damages can be reasonably estimated.

As assessments and cleanups proceed, the liability is adjusted based on progress made in determining the extent of remedial actions and related costs and damages. The liability can change

substantially due to factors such as the nature and extent of contamination, changes in remedial requirements, and technological changes. Therefore, it is not possible to determine the outcomes or to estimate with any degree of accuracy the potential costs for certain of these matters.

The following discussion provides additional details regarding the current status of Alcoa’s significant sites where the final outcome cannot be determined or the potential costs in the future cannot be estimated.

Massena, NY. Alcoa has been conducting investigations and studies of the Grasse River, adjacent to Alcoa’s Massena, New York plant site, under order from the U.S. Environmental Protection Agency (EPA) issued under the Comprehensive Environmental Response, Compensation and Liability Act, also known as Superfund. Sediments and fish in the river contain varying levels of polychlorinated biphenyl (PCB).

~~During 2000 and 2001, Alcoa completed certain studies and investigations on the river, including pilot tests of sediment-capping techniques, and other remediation technologies.~~ In ~~June~~ 2002, Alcoa submitted ~~a final~~an Analysis of Alternatives Report ~~based on these evaluations and included additional~~that detailed a variety of remedial alternatives ~~required by the EPA. The range of~~with estimated costs ~~associated with the remedial alternatives evaluated in the 2002 report is between~~ranging from $2 ~~and~~to $525. Alcoa believes that rational, scientific analysis supports a remedy involving the containment of sediments in place via natural or man-made processes. Based on an assessment of the EPA decision-making process at the end of 2002, Alcoa concluded thatBecause the selection of the $2 alternative ~~based on natural recovery only,~~(natural recovery) was ~~remote.~~ considered remote, Alcoa adjusted the reserve for the Grasse River in 2002 to $30 representing the low end of the range of possible alternatives, as no single alternative could be identified as more probable than the others.

In June of 2003, based on river observations during the spring of 2003, the EPA requested that Alcoa gather additional field data to assess the potential for sediment erosion from winter river ice formation and breakup. ~~Alcoa has collected~~The results of these additional studies, submitted in a significant portion of the additional data and is in the process of data analysis and determining how this phenomenon should be factored into the range of remedial alternatives being considered. It is anticipated that a report ~~of findings will be issued~~ to the EPA in April of 2004, suggest that this phenomenon has the ~~second~~potential to occur approximately every 10 years and may impact sediments in certain portions of the river under all remedial scenarios. The EPA informed Alcoa that a final remedial decision for the river could not be made without substantially more information, including river pilot studies on the effects of ice formation and breakup on each of the remedial techniques. The EPA requested that Alcoa consider a Remedial Options Study to gather this information. The scope of this study includes sediment removal and capping, the installation of an ice control structure, and significant monitoring.

In May of 2004, Alcoa agreed to perform the study at an estimated cost of $35. Most of the work should be completed by the fourth quarter of ~~2004. Subsequent to this submittal,~~2005. The findings will be incorporated into a revised Analysis of Alternatives Report, which is expected to be submitted in 2006. This information will be ~~submitted at~~used by the EPA to propose a ~~date to be determined.~~remedy for the entire river.

Alcoa ~~continues~~adjusted the reserves this quarter to ~~believe that alternatives involving~~include the ~~largest amounts of sediment removal should not be selected~~$35 for the ~~Grasse River remedy. Therefore, Alcoa believes that alternatives that should reasonably be considered for selection range from engineered capping and natural recovery of~~Remedial Options Study. This is in addition to the $30 ~~to a combination of moderate dredging, capping and natural recovery of $90. Accordingly, Alcoa adjusted the reserve for the Grasse River to $30 at the end of 2002, representing the low end~~previously reserved. Currently, none of the ~~range~~existing alternatives in the 2002 Analysis of ~~possible alternatives, as no one~~Alternatives Report is more probable than the others and the results of the ~~alternatives is more likely~~Remedial Options Study are necessary to ~~be selected than any other.~~revise the scope and estimated cost of many of the current alternatives.

The EPA’s ultimate selection of a remedy could result in additional liability. ~~However, as the process continues, it allows for input that can influence the scope and cost of the remedy that will be selected by the EPA in its issuance of the formal Record of Decision (ROD).~~ Alcoa may be required to record a subsequent reserve adjustment at the time the ~~ROD~~EPA’s Record of Decision is issued.

Sherwin, TX. In connection with the sale of the Sherwin alumina refinery in Texas, which was required to be divested as part of the Reynolds merger in 2000, Alcoa has agreed to retain responsibility for

the remediation of then existing environmental conditions, as well as a pro rata share of the final closure of the active waste disposal areas, which remain in use. Alcoa’s share of the closure costs is proportional to the total period of operation of the active waste disposal areas. Alcoa estimated its liability for the active disposal areas by making certain assumptions about the period of operation, the amount of material placed in the area prior to closure, and the appropriate technology, engineering, and regulatory status applicable to final closure. The most probable cost for remediation has been reserved. It is reasonably possible that an additional liability, not expected to exceed $75, may be incurred if actual experience varies from the original assumptions used.

Based on the foregoing, it is possible that Alcoa’s results of operations, in a particular period, could be materially affected by matters relating to these sites. However, based on facts currently available, management believes that adequate reserves have been provided and that the disposition of these matters will not have a materially adverse effect on the financial position or liquidity of the company.

Alcoa’s remediation reserve balance at ~~March 31,~~June 30, 2004 was $416 and $395 at December 31, 2003 ~~was $387 and $395~~ (of which $65 was classified as a current liability in both periods), ~~respectively,~~ and reflects the most probable costs to remediate identified environmental conditions for which costs can be reasonably estimated. Remediation costs charged to the reserve in the 2004 ~~first quarter~~six-month period were approximately ~~$7.~~

$17. They include expenditures currently mandated, as well as those not required by any regulatory authority or third party. The reserve balance was ~~reduced~~increased by ~~$1, net~~$38 in the 2004 ~~primarily~~six-month period, principally due to the additional reserve recorded for ~~adjustments based on recent assessments of remaining work required at certain sites.~~the Grasse River site.

Included in annual operating expenses are the recurring costs of managing hazardous substances and environmental programs. These costs are estimated to be about 2% of cost of goods sold.

In addition to the risks inherent in its operations, Alcoa is exposed to financial, market, political and economic risks. The following discussion provides additional detail regarding Alcoa’s exposure to the risks of changing commodity prices, foreign exchange rates, and interest rates.

Alcoa’s commodity and derivative activities are subject to the management, direction, and control of the Strategic Risk Management Committee (SRMC). The SRMC is composed of the chief executive officer, the chief financial officer, and other officers and employees that the chief executive officer selects. The SRMC reports to the Board of Directors on the scope of its derivative activities.

All of the aluminum and other commodity contracts, as well as various types of derivatives, are held for purposes other than trading. They are used ~~primarily~~principally to mitigate uncertainty and volatility, and to cover underlying exposures. The company is not involved in energy-trading activities, weather derivatives, or other nonexchange commodity trading activities.

Commodity Price Risks - Alcoa is the world’s leading producer of aluminum ingot and fabricated products. As a condition of sale, customers often require Alcoa to enter into forward-dated, fixed-price commitments. These commitments expose Alcoa to the risk of fluctuating aluminum prices between the time the order is committed and the time the order is shipped.

Alcoa’s aluminum commodity risk management policy is to manage, through the use of futures contracts, the aluminum price risk associated with a portion of its fixed-price firm commitments. At ~~March 31,~~June 30, 2004, these contracts totaled approximately ~~607,000~~793,000 mt with a fair value gain of approximately ~~$108~~$99 (pre-tax).

Alcoa purchases natural gas, fuel oil, and electricity to meet its production requirements. These purchases expose the company to the risk of higher prices. To hedge a portion of this risk, Alcoa enters into long positions, principally using futures contracts. Alcoa follows a stable pattern of purchasing these commodities; therefore, it is highly likely that anticipated purchases will occur. The fair value of these contracts was a gain of approximately ~~$82~~$81 (pre-tax) at ~~March 31,~~June 30, 2004.

Currencies- Alcoa is subject to exposure from fluctuations in foreign currencies. Foreign currency exchange contracts may be used from time to time to hedge the variability in cash flows from the forecasted payment or receipt of currencies other than the functional currency. These contracts cover periods commensurate with known or expected exposures, generally within three years. The fair value of these contracts was a loss of approximately ~~$10~~$3 (pre-tax) at ~~March 31,~~June 30, 2004.

Interest Rates- Alcoa uses interest rate swaps to help maintain a strategic balance between fixed- and floating-rate debt and to manage overall financing costs. The company has entered into pay floating, receive fixed interest rate swaps to change the interest rate risk exposure of its outstanding debt. The fair value of these swaps was a ~~gain~~loss of approximately ~~$45~~$145 (pre-tax) at ~~March 31,~~June 30, 2004.

Alcoa ~~also uses~~previously used interest rate swaps to establish fixed interest rates on anticipated borrowings between June 2005 and June 2006. ~~The~~Due to a change in forecasted borrowing requirements, resulting from the early retirement of debt in June 2004 and a forecasted increase in future operating cash flows resulting from improved market conditions, it is no longer probable that the anticipated borrowings ~~have a high probability~~will occur in 2005 and 2006. Therefore, Alcoa recognized $33 of ~~occurrence because~~gains that had been deferred on previously settled swaps and $44 of additional gains to unwind the ~~proceeds will be used to fund debt maturities and anticipated capital expenditures. Alcoa has $1,000 of~~remaining interest rate ~~swaps outstanding that will establish fixed interest rates on anticipated borrowings~~swaps. These gains were recorded in other income. See Note B in Part I, Item I for additional information.

Embedded Derivatives - During the second quarter of ~~$500~~2004, Alcoa entered into a long-term power supply contract. The power contract provides for increased pricing if the LME exceeds a certain price. This pricing feature in the contract is considered an embedded derivative and is marked to market through earnings. The impact to earnings in the second quarter of ~~debt through 2016 and $500 of debt through 2036. The fair value of these swaps~~2004 was ~~a loss of approximately $47 (pre-tax) at March 31, 2004.~~not material.

Material Limitations - The disclosures with respect to commodity prices, interest rates, and foreign exchange risk do not take into account the underlying commitments or anticipated transactions. If the underlying items were included in the analysis, the gains or losses on the futures contracts may be offset. Actual results will be determined by a number of factors that are not under Alcoa’s control and could vary significantly from those factors disclosed.

Alcoa is exposed to credit loss in the event of nonperformance by counterparties on the above instruments, as well as credit or performance risk with respect to its hedged customers’ commitments. Although nonperformance is possible, Alcoa does not anticipate nonperformance by any of these parties. Futures contracts are with creditworthy counterparties and are further supported by cash, treasury bills, or irrevocable letters of credit issued by carefully chosen banks. In addition, various master netting arrangements are in place with counterparties to facilitate settlement of gains and losses on these contracts.

Alcoa’s Chief Executive Officer and Chief Financial Officer have evaluated the company’s disclosure controls and procedures as of the end of the period covered by this report, and they have concluded that these controls and procedures are effective.

There have been no significant changes in internal control over financial reporting that occurred during the quarter ended ~~March 31,~~June 30, 2004, that have materially affected, or are reasonably likely to materially affect, the registrant’s internal control over financial reporting.

As previously reported, in ~~May through October~~2001 and 2002, ~~eleven~~two companion lawsuits were filed ~~against~~in the Court of Lafayette County, Arkansas on behalf of nearly 400 current or former residents of the City of Stamps, Arkansas, the City of Stamps, and former employees of Red River Aluminum, Inc. (RRA), a dross processor. The 2001 action was transferred to Miller County, Arkansas. The suits name 12 defendants (including Alumax Inc., Reynolds Metals Company and Alcoa inInc.) that sent dross to RRA for processing. Plaintiffs have filed claims for personal injuries and property damage and have alleged that the District Court of Wharton County, Texas, five of which have since been dismissed. In the same timeframe, another lawsuit was filed in the United States District Court, Southern District of Texas, Victoria Division, but was later dismissed. The cases were originally removed to federal court, but all were remanded back to state court in Wharton County and consolidated. The lawsuits seek to recover damagesdefendants violated Arkansas environmental statutes relating to the ~~presence of trichloroethylene (TCE)~~alleged contamination associated with RRA’s operations in the groundwater near a former Reynolds extrusion facility in El Campo, Texas. Additional defendants included in some of the lawsuits are the current owners to whom Reynolds sold the facility in 1997, Bon L. Campo Limited Partnership (Bon L. Campo) and Tredegar Corporation, a former plant owner from 1968-71, Whittaker Corporation, and two neighboring businesses. Some of the cases request class certification to include other allegedly affected individuals as plaintiffs. Damages sought include those for the contamination of private wells, diminution of property value, medical monitoring and punitive damages.Stamps. The ~~only significant personal injury claim~~2001 action was settled in ~~2003. Reynolds owned~~May 2004. The cost of the settlement was previously reserved for and ~~operated~~was not material to Alcoa. The 2002 action was dismissed, without prejudice, at the ~~facility from 1971 to 1997 and sold it to Bon L. Campo before~~request of plaintiffs in June 2004.

As previously reported, in July 1999, Alcoa ~~acquired Reynolds. Reynolds and~~Aluminio S.A. received notice that an administrative proceeding was commenced by Brazil’s Secretary of Economic Law of the Ministry of Justice against Brazilian producers of primary aluminum, including Alcoa ~~are currently participating~~Aluminio. The suit alleges collusive action in the ~~Voluntary Cleanup Program under~~pricing of primary aluminum in violation of Brazilian antitrust law. Alcoa Aluminio has presented its defense and has been awaiting the ~~supervision~~decision of the ~~Texas Commission on Environmental Quality~~Secretary of Economic Law. If the Secretary of Economic Law determines that the antitrust law was violated, then the action may be further prosecuted by the Administrative Council of Economic Defense (known as CADE). Brazilian law provides for civil and ~~investigating~~criminal sanctions for violations of antitrust law, including fines ranging from 1% to 30% of a company’s revenue during the ~~area to determine~~last fiscal year.
