NEW YORK, NY – October 7, 2009 – Alcoa (NYSE: AA) today announced third quarter 2009 income from continuing operations of $73 million, or $0.07 per diluted share, compared to a loss from continuing operations of $312 million, or $0.32 per share, in the second quarter 2009. Income from continuing operations in the third quarter of 2008 was $306 million, or $0.37 per share. Excluding restructuring and special items, income for the third quarter 2009 was $39 million, or $0.04 per share.

The third quarter of 2009 had net income of $77 million, or $0.08 per share, compared with a net loss for the second quarter of 2009 of $454 million, or $0.47 per share. Net income in the third quarter of 2008 was $268 million, or $0.33 per share. Discontinued operations for the third quarter of 2009 had income of $4 million, or $0.01 per share. The second quarter of 2009 had a loss of $142 million, or $0.15 per share.

Restructuring and special items in the quarter totaled $34 million, or $0.03 per share. These items included a gain on the completion of a transaction to acquire bauxite and alumina refining interests in Suriname of $35 million and restructuring charges of $17 million before tax ($1 million after tax and noncontrolling interests).

Revenues for the quarter were $4.6 billion compared with $4.2 billion in the second quarter of 2009, a nine percent increase. Revenues were $7.0 billion in the third quarter of 2008. Sequentially, revenues were helped by an increase in realized prices for primary aluminum to $1,972 per metric ton from $1,667 per metric ton in the second quarter, as well as stabilization in the end markets.

“The financial and operational measures we took in the first half of the year are having a strong positive impact on our cash position and profitability,” said Klaus Kleinfeld, Alcoa President and Chief Executive Officer. “Despite unfavorable currency and energy headwinds, our performance this quarter indicates that Alcoa is weathering the economic storm and is in excellent shape to benefit when the market recovers.”

The Company is exceeding all the targets of its Cash Sustainability Program, which helped to offset negative currency and energy impacts in the quarter of $89 million. Overhead savings are $375 million, 188 percent of the full year target for 2009, and procurement savings are $1.61 billion, 107 percent of the full-year target. Reductions in working capital have generated $780 million in cash, or 98 percent of the 2009 target of $800 million.

Cash from operations in the quarter was $184 million compared with $328 million in the second quarter of 2009 as working capital reductions continued, yet at a slower pace due to rising prices. Cash from operations in the third quarter 2008 was a negative $93 million. EBITDA in the quarter improved by $454 million from zero in the second quarter of 2009.

During the quarter, the Company received the final $520 million of proceeds from the exiting of the Shining Prospect venture and finished the quarter with $1.1 billion of cash on hand. The Company’s debt-to-capital ratio stood at 38.3 percent at the end of the quarter, a 140 basis point reduction from the second quarter of 2009.

Capital expenditures in the quarter were $370 million, on-target to reach the 2009 goal of a nearly 50 percent reduction from 2008. In the quarter, the Company commissioned its Juruti bauxite mine in Brazil and new lithographic sheet operations in Bohai, China. This follows the opening of a new end and tab line in Russia in late-June. These investments will lower costs and position the Company well for growth as economies improve in those important markets.

Revenues for the first nine months of 2009 were $13.0 billion, compared to $21.2 billion in the first nine months of 2008. Income from continuing operations for the first nine months of 2009 showed a loss of $719 million, or $0.78 per share, compared with income of $1.2 billion, or $1.40 per share, in the first nine months of 2008. The nine months of 2009 showed a net loss of $874 million, or $0.95 per share, compared to net income of $1.1 billion, or $1.35 per share, in the first nine months of 2008.

In the second half of 2009, there are signs that key markets the Company operates in are stabilizing. Due to low inventories at distributors and rising shipments, regional premiums are improving and global aluminum consumption is expected to increase 11 percent in the second half of 2009.

Segment Results

Alumina

After tax operating income (ATOI) was $65 million, a $72 million improvement from the second quarter. Alumina production increased nine percent or 305 thousand metric tons and average third-party realized pricing improved 13 percent, helped by rising LME aluminum prices and improved demand. A $58 million benefit from the Suriname acquisition was partially offset by negative currency impacts of $28 million and higher energy costs of $13 million. The Juruti mine was officially commissioned this quarter and combined with the Sao Luis refining expansion, will place Alcoa’s overall refining system in the top quartile on the global cost curve in terms of low-cost production.

Primary Metals

ATOI improved $170 million sequentially to a loss of $8 million due primarily to improved pricing. Smelting production decreased 25 thousand metric tons and third-party realized pricing was up $305 per metric ton, or 18 percent, as LME pricing and regional premiums continued to improve. Results were negatively impacted by $29 million of currency effects. The production run rate now stands at 3.5 million metric tons with approximately 20 percent of primary production curtailed.

Flat-Rolled Products

ATOI improved $45 million from the second quarter of 2009 through improved orders and significant cost reduction efforts. Shipments for the quarter increased six percent sequentially and revenue increased seven percent. Every key end market except aerospace saw revenue gains, including automotive which increased 21 percent from the second quarter of 2009. Improved shipments and cost reduction efforts more than offset the impacts of product mix and currency effects in Australia. This quarter the Bohai flat-rolled products facility in China was inaugurated and it is already serving customers in the printing, transportation, electronics, and packaging industries.

Engineered Products and Solutions

ATOI for the quarter of $75 million was 15 percent below the sequential quarter results driven by continued aerospace destocking, industrial gas turbine market declines, and normal seasonal impacts. This was partially mitigated by improved demand in commercial transportation and strong results from spend reduction efforts.

Alcoa will hold its quarterly conference call at 5:00 PM Eastern Time on October 7, 2009 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.”

The difference between certain segment totals and consolidated amounts is in Corporate.

(1) In the second quarter of 2009, management approved the movement of Alcoa’s hard alloy extrusions business from the Flat-Rolled Products segment to the Engineered Products and Solutions segment. This move was made to capture market, customer, and manufacturer synergies through the combination of the hard alloy extrusions business with the power and propulsion forgings business. Prior period amounts were reclassified to reflect this change.

(2) Prior period segment information for Engineered Products and Solutions was reclassified to reflect the movement of the Electrical and Electronic Solutions business to discontinued operations in the fourth quarter of 2008.

(3) On February 29, 2008, Alcoa completed the sale of its packaging and consumer businesses to Rank Group Limited. The Packaging and Consumer segment no longer contains any operations.

(4) On January 1, 2009, Alcoa adopted changes issued by the Financial Accounting Standards Board to consolidation accounting and reporting. These changes, among others, require that minority interests be renamed noncontrolling interests for all periods presented.

Adjusted Income

	Quarter ended September 30, 2009
	Income			Earnings per share
Net income attributable to Alcoa	$	77		$	0.08
Income from discontinued operations		4
Income from continuing operations attributable to Alcoa		73			0.07
Gain on acquisition in Suriname		(35	)
Restructuring and other charges		1
Income from continuing operations attributable to Alcoa – as adjusted	$	39			0.04

Income from continuing operations attributable to Alcoa – as adjusted is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management reviews the operating results of Alcoa excluding the impacts of restructuring and other charges and transaction impacts from acquisitions and divestitures. There can be no assurances that similar items will not occur in future periods. To compensate for this limitation, management believes that it is appropriate to consider both Income from continuing operations attributable to Alcoa determined under GAAP as well as Income from continuing operations attributable to Alcoa – as adjusted.

Alcoa’s definition of EBITDA is net margin plus depreciation, depletion, and amortization. Net margin is equivalent to Sales minus the following items: Cost of goods sold; Selling, general administrative, and other expenses; Research and development expenses; and Provision for depreciation, depletion, and amortization. EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because EBITDA provides additional information with respect to Alcoa’s operating performance and the Company’s ability to meet its financial obligations.
