ALCOA ANNOUNCES 3^rd QUARTER 2006 INCOME FROM CONTINUING

OPERATIONS OF $540 MILLION, or $0.62 PER SHARE, UP 89% FROM YEAR AGO

Highlights:

• Income from continuing operations up 89% versus year-ago quarter.

• Revenues 19% higher than year-ago quarter.

• Cash from operations was $748 million including the impact of a discretionary $200 million pension contribution, 52% higher than the year-ago quarter and 94% higher year-to-date.

• Debt-to-capital ratio at 32.8%, within target range despite major investments in strategic growth projects.

• Year-to-date income from continuing operations $1.9 billion, or $2.17 per share, up 82% from year ago.

• Year-to-date annualized return on capital of 14.3%, up from 8.7% in 2005.

NEW YORK, NY – October 10, 2006 – Alcoa (NYSE: AA) today announced third quarter 2006 income from continuing operations of $540 million, or $0.62 per diluted share, an 89 percent increase from the third quarter of 2005. As expected, due to seasonal slow-downs and lower metal prices, income was lower on a sequential basis, down from $0.85 in the second quarter.

In the first nine months of 2006, Alcoa has generated more profits than in any full year in the company’s history. Year-to-date income from continuing operations was $1.9 billion, 82 percent higher than the same period in 2005.

Net income for the quarter was $537 million, or $0.61, an 85 percent increase from 2005’s $0.33 and 28 percent below the $0.85 in the second quarter.

Revenues for the quarter increased 19 percent from a year ago to $7.6 billion. Compared to the second quarter of 2006, sales decreased 2 percent primarily due to lower metal prices and seasonality. Prices for aluminum on the London Metal Exchange declined six percent this quarter.

“We continue to drive stronger performance than our results in 2005, with both the top and bottom line showing double-digit improvements over the third quarter of last year,” said Alain Belda, Alcoa Chairman and CEO. “2006 is already the strongest in Alcoa’s history, and we will continue to deliver in the fourth quarter.

“In July, we said the third quarter would be solid, but would reflect the traditional seasonal slow-down and lower metal prices. In fact, the quarter was the third best in company history even though metal prices on the LME declined six percent. While the North American automotive and the housing construction markets are softening, most of our downstream markets continue to be strong – especially aerospace and commercial transportation,” Belda added.

Cash from operations for the quarter was $748 million including the impact of a discretionary $200 million contribution to the company’s pension plans. Year-to-date, cash from operations is more than $1.2 billion, a 94 percent increase from a year ago.

Balance Sheet and Growth Projects

During the quarter, the company made strong progress on projects designed to seize growth as aluminum consumption is projected to double in the next 14 years. The Alcoa Fjardaal smelter in Iceland is now 75 percent complete and is expected to produce its first metal in the second quarter of 2007. In Brazil, the new Juruti bauxite mine and the expansion of the Sao Luis alumina refinery are underway. The refinery will produce an additional 2.1 million mtpy beginning in 2009. In North America, work continued on environmental upgrades at the company’s Warrick, Indiana smelter which will help secure its power generation self-sufficiency. At the Intalco smelter in Ferndale, WA, the company will be starting up a second potline which will produce an additional 7,500 metric tons per month beginning in the first half of 2007.

Capital expenditures for the quarter were $737 million, with 75 percent dedicated to growth projects. Year to-date, the company has invested $1.4 billion in growth projects, or approximately 67 percent of capital expenditures.

In the quarter, Alcoa also announced a definitive agreement to sell its Home Exteriors vinyl siding business. That sale, which will generate more than $300 million in cash to fund growth projects, is expected to be completed in the fourth quarter of 2006.

Days of working capital were relatively flat in the quarter compared to the third quarter of 2005. The Company’s debt-to-capital ratio stood at 32.8 percent at the end of the quarter, within the Company’s target range.

During the current quarter, the company’s effective tax rate was 24.7 percent. In the quarter, the Company recorded a discrete tax benefit of $18 million related to the cumulative correction of its deferred tax assets attributable to an international location.

The Company’s year to date annualized return on capital was 14.3 percent, compared to 8.7 percent a year ago. On a trailing four quarters basis, return on capital for the third quarter 2006 was 14.1 percent after excluding investments on growth, and 12.2 percent including those investments.

Segment and Other Results

Alumina – After-tax operating income (“ATOI”) was $271 million, down $7 million from the previous quarter, but up 74 percent from the year-ago quarter. Unfavorable currency effects, energy prices, and mix offset higher sales volumes supported by record production levels of 3,890 KMT in the quarter.

Primary Metals – Segment ATOI was $346 million, down $143 million or 29 percent from the prior quarter and up 106 percent from the year-ago quarter. The ATOI decrease resulted from lower LME prices, higher raw material costs and unfavorable currency. Third-party realized metal prices declined $108 per ton, or four percent, to $2,620 per ton. The Company purchased roughly 130 kmt of primary metal for internal use as part of its strategy to sell value-added products.

Flat-Rolled Products – ATOI for the segment was $48 million, down 39 percent from the prior quarter and down 41 percent from the year-ago quarter. The decline was primarily due to seasonal shutdowns and mill outages in North America and Europe, and an increase in direct material and energy costs. These impacts were somewhat offset by a more favorable product mix. Included in the results were $13 million in continuing start-up costs for new facilities in Russia and China as part of the long-term growth strategy.

Extruded and End Products – ATOI declined $1 million from the prior quarter due to seasonally lower volumes, offset by a more favorable mix. Segment ATOI remained flat in comparison to the prior year quarter.

Engineered Solutions – Segment ATOI declined $25 million from the prior quarter due to scheduled summer shutdowns in the auto industry coupled with lower demand in the North American automotive market. However, ATOI rose $41 million, or 121 percent, above the prior year quarter. Strong demand in the aerospace and commercial vehicle markets, continued productivity gains and targeted price increases led to the improved results.

Packaging and Consumer – Segment ATOI was lower by $13 million versus the previous quarter and $4 million from the year-ago quarter primarily due to seasonal weakness in Food Packaging and Closures and higher resin costs, partially offset by continued strength in the Consumer business. It is anticipated that the lagged recovery of the third quarter raw material cost increases will benefit the fourth quarter.

Alcoa will hold its quarterly conference call at 5:00 PM Eastern Time on October 10th to present the quarter’s results. The meeting will be webcast via alcoa.com. Call information and related details are available at www.alcoa.com under “Invest.”

Return on capital, excluding growth investments		14.1	%

Return on capital, excluding growth investments is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because it provides greater insight with respect to the underlying operating performance of the company’s productive assets. The company has significant growth investments underway in its upstream and downstream businesses, as previously noted, with expected completion dates over the next several years. As these investments generally require a period of time before they are productive, management believes that a return on capital measure excluding these growth investments is more representative of current operating performance.

(1) The Bloomberg Methodology calculates ROC based on trailing four quarters. Average balances are calculated as (September 2005 ending balance + September 2006 ending balance) divided by 2.

(2) The Annualized Methodology numerator amounts are calculated using the first nine months of 2006 balances divided by 9 and multiplying that result by 12. Average balances are calculated as (September 2006 ending balance + December 2005 ending balance) divided by 2.

(3) Calculated as total shareholders’ equity, less preferred stock.
