Alcoa Reports Strong Third Quarter 2014 Profits

as Portfolio Transformation Delivers

3Q 2014 Highlights

3Q 2014 Portfolio Transformation Highlights

New York, October 8, 2014 – Lightweight metals leader Alcoa (NYSE:AA) today reported a surge in third quarter profits as the Company’s repositioning continues accelerating. Alcoa is aggressively transforming its portfolio by building out its multi-material value-add businesses to capture profitable growth and by creating a lower cost, globally competitive commodity business.

In third quarter 2014, Alcoa reported net income of $149 million, or $0.12 per share, which includes $221 million in special items largely tied to previously announced restructurings to further improve the cost structure of the commodity business. Sequentially, third quarter 2014 results compare to net income of $138 million, or $0.12 per share, in second quarter 2014. Year-over-year, third quarter 2014 results increased from net income of $24 million, or $0.02 per share, in third quarter 2013.

Excluding the impact of special items, net income was $370 million, or $0.31 per share, up 71 percent from net income of $216 million, or $0.18 per share, in the sequential period. Year-over-year, net income excluding special items more than tripled from net income of $120 million, or $0.11 per share, led by strong productivity and pricing.

Third quarter 2014 revenues climbed 7 percent sequentially and 8 percent year-over-year to $6.2 billion. Nearly half of the year-over-year revenue improvement resulted from organic growth. Favorable metal pricing and higher energy sales also contributed to revenues.

“This quarter is a clear data point that Alcoa’s transformation is delivering,” said Klaus Kleinfeld, Alcoa Chairman and Chief Executive Officer. “Our downstream business again achieved historically high profitability, the midstream maintained disciplined cost control while capturing growth, and Primary Metals performed at levels not seen since before the downturn. This strong quarter is the direct result of our intense focus on repositioning our portfolio, and we’re just hitting our stride.”

Engineered Products and Solutions (EPS), the downstream business, achieved its best ever quarterly results, delivering $209 million in after-tax operating income (ATOI). In the midstream business, Global Rolled Products’ (GRP) ATOI rose 45 percent year-over-year to $103 million. The upstream commodity business, comprising Alumina and Primary Metals, improved performance for the 12^th consecutive quarter. Primary Metals’ adjusted EBITDA per metric ton was $612, the strongest since second quarter 2008, reflecting a lower cost, reshaped commodity business better positioned to capture greater profitability from higher metal prices.

Special items in third quarter 2014 included $202 million in restructuring-related costs, 60 percent non-cash, associated with previously announced plant closures of the Portovesme and Point Henry smelters and the Australian rolling mills. There were also costs associated with the Firth Rixson acquisition, an unfavorable impact of mark-to-market changes on certain energy contracts, and a gain from the sale of an equity investment in a China rolling mill.

Continued Growth Across End Markets

Alcoa continues to project 2014 global aerospace sales growth of 8 to 9 percent driven by robust demand for both large commercial aircraft and regional jets. The Company tightened its projection for 2014 global automotive production growth from a previous range of 1 to 4 percent in the second quarter to 2 to 4 percent. Global packaging sales growth of 2 to 3 percent and global building and construction sales growth of 4 to 6 percent in 2014 remain unchanged. In the industrial gas turbine market, the Company’s projected decline of 8 to 12 percent, on lower orders for new gas turbines and spare parts, also remains unchanged for the year.

For the second time this year, Alcoa increased its 2014 estimate of production growth for the North America commercial transportation market to a range of 16 to 20 percent from a previous range of 10 to 14 percent in the second quarter, and 5 to 9 percent in the first quarter. The higher estimate is based in part on a 43 percent increase in third quarter truck orders year-over-year and strong backlogs. Globally, Alcoa continues to expect a flat commercial transportation market of negative 1 to positive 3 percent in 2014 due to ongoing weakness in the European market.

Additionally, Alcoa reaffirmed its 7 percent global aluminum demand growth projection for 2014. The Company sees a global aluminum deficit of 671,000 metric tons in 2014 and a further tightening of the alumina market, with a surplus declining to 389,000 metric tons from 824,000 metric tons in second quarter 2014.

Value-Add Portfolio Transformation

Alcoa’s strategy to build out its innovative, multi-material value-add businesses to capture profitable growth continues to make progress.

In second quarter 2014, the Company announced it would acquire global jet engine component leader Firth Rixson. The acquisition is moving toward completion and is expected to close by year-end. Financing for the acquisition is complete, U.S. regulatory approval has been granted and other approvals are on track.

Firth Rixson’s revenues are expected to grow 60 percent over the next three years, from $1 billion in 2013 to $1.6 billion, and to contribute $350 million EBITDA in 2016. When the acquisition is completed, it is also expected to grow Alcoa’s annual aerospace revenues by 20 percent, from $4 billion in 2013 to $4.8 billion on a pro forma basis. Firth Rixson is expected to increase the contribution of the aerospace segment to Alcoa’s value-add revenues from 30 percent to nearly 35 percent.

Positioning itself to better meet the aerospace industry’s growing demand for lighter, next generation materials, Alcoa opened the world’s largest Al-Li plant in Lafayette, Indiana this month. The plant has already contracted $100 million in Al-Li revenues for 2017. This is the Company’s third Al-Li expansion, with the first two at the Alcoa Technical Center outside Pittsburgh and at the Kitts Green facility in the United Kingdom.

Underpinning Alcoa’s aerospace leadership, the Company announced two multi-year contracts in the third quarter worth more than $2 billion combined. Alcoa’s EPS segment was awarded a $1.1 billion Pratt & Whitney contract to supply jet engine components, including the world’s first advanced aluminum alloy jet engine fan blade forging. The agreement also includes developing a fan blade forging using Alcoa’s third-generation Al-Li alloy for Pratt & Whitney’s PurePower^® engines.

Alcoa’s GRP segment signed a multi-year supply contract with Boeing worth more than $1 billion, the largest ever between the two companies. The agreement includes future collaboration on advanced aerospace alloys.

In the automotive business, GRP produced a record volume of automotive sheet in the third quarter to meet increasing demand for aluminum-intensive vehicles. The Company’s Davenport, Iowa facility continued to ramp up production and is supplying Ford with high strength automotive sheet made with a military-grade aluminum alloy for the new F-150. The auto expansion in Alcoa, Tennessee is on schedule to open in mid-2015.

In the Wheels and Transportation Products business, Alcoa rolled out its lightest ever heavy-duty truck wheel in Europe to help fleets increase payload and fuel efficiency. The Ultra ONE™ with MagnaForce™ alloy will be available in Europe during the second half of 2015.

Upstream Portfolio Transformation

In the upstream, Alcoa continues to take strategic actions to create a globally competitive commodity business, reducing high-cost operating smelting capacity by 1.2 million metric tons, or 28 percent, since 2007. The Company is also executing previously announced smelter closures to further optimize its commodity portfolio.

In the third quarter, Alcoa announced plans to permanently close its primary aluminum smelter in Portovesme, Italy, which has been curtailed since November 2012. The closure will reduce Alcoa’s global smelting capacity by 150,000 metric tons. The Company also safely completed the previously announced closure of the 190,000 metric ton Point Henry smelter in Australia. In addition, Alcoa reached an agreement for Sural Laminated Products of Canada, Inc. to acquire the 90,000 metric ton Bécancour, Quebec rod mill.

Future actions to further reshape the commodity business, include:

In Saudi Arabia, progress continued at the Ma’aden-Alcoa joint venture. The smelter is fully operational and generated profits in the third quarter. The refinery, which will be the lowest-cost in the world, is 98 percent complete and the bauxite mine is 73 percent complete.

Investing in the world’s lowest-cost aluminum complex and closing high cost capacity supports the Company’s goal to lower its position on the world aluminum production cost curve to the 38^th percentile and the alumina cost curve to the 21^st percentile, by 2016.

Financial Performance

Alcoa continues to drive strong performance across all businesses, delivering $306 million in third quarter productivity gains and $862 million year-to-date against an $850 million 2014 annual target. Productivity gains have been driven by process improvements and procurement savings across all segments. Alcoa managed growth capital expenditures of $325 million against a $500 million annual target and controlled sustaining capital expenditures of $425 million against a $750 million annual plan. Contributions in the Saudi Arabia joint venture project were on track at $69 million invested against a $125 million annual plan.

Cash from operations was $249 million in the quarter and free cash flow was a negative $34 million. Alcoa ended the quarter with cash on hand of $3.3 billion, which includes the net proceeds, $2.45 billion, of the public offerings of notes and mandatory convertible preferred stock represented by depositary shares to finance the proposed acquisition of Firth Rixson. Alcoa had $1.2 billion cash on hand in second quarter 2014.

The Company reported an average of 32 days working capital for the quarter, up one day from third quarter 2013, and down 15 days since third quarter 2009. Sequentially, average days working capital was one day lower.

Segment Performance

Engineered Products and Solutions

ATOI was a quarterly record of $209 million, up $5 million, or 2 percent, sequentially and up $17 million, or 9 percent, year-over-year. EPS delivered its eighteenth consecutive quarter of year-over-year ATOI improvement. On a sequential basis, favorable productivity drove the improvement. This segment reported a record adjusted EBITDA margin of 23.5 percent, compared to 23.1 percent for second quarter 2014 and 22.5 percent for the same quarter last year.

Global Rolled Products

ATOI in the third quarter was $103 million compared to $79 million in second quarter 2014, a 30 percent improvement, and $71 million in third quarter 2013. Sequentially, ATOI improved on higher metal prices, seasonal demand for can sheet in North America and productivity. Results were partially offset by the impact of European summer shutdowns. The segment will continue to ramp up production in the fourth quarter to serve growing demand for aluminum intensive vehicles. Adjusted EBITDA per metric ton was $409, up from $313 in second quarter 2014.

Alumina

ATOI in the third quarter was $62 million, up $24 million sequentially, and down $5 million year-over-year. The increase in sequential ATOI was primarily due to higher volume, favorable foreign exchange rates, increased pricing on London Metal Exchange-based contracts and increased productivity. Results were partially offset by lower Alumina Price Index-based pricing and higher energy costs in Australia. Adjusted EBITDA per metric ton increased $7 from second quarter 2014 to $46 per metric ton in third quarter 2014.

Primary Metals

ATOI in the third quarter was $245 million, up $148 million sequentially from $97 million, and up $237 million from $8 million in third quarter 2013. Third-party realized price in third quarter 2014 was $2,538 per metric ton, up 11 percent sequentially, and up 16 percent year-over-year. Sequential results were driven by realized prices, lower alumina costs, increased productivity, the ramp up of the Saudi Arabia smelter, favorable foreign exchange rates and increased power sales. Results were partially offset by charges related to previously announced smelter closures in Italy and Australia and seasonally higher power costs. Adjusted EBITDA per metric ton was $612, $275 per metric ton higher than second quarter 2014.

Non-GAAP Financial Measures

Some of the information included in this release is derived from Alcoa’s consolidated financial information but is not presented in Alcoa’s financial statements prepared in accordance with accounting principles generally accepted in the United States of America (GAAP). Certain of these data are considered “non-GAAP financial measures” under SEC rules. These non-GAAP financial measures supplement our GAAP disclosures and should not be considered an alternative to the GAAP measure. Reconciliations to the most directly comparable GAAP financial measures and management’s rationale for the use of the non-GAAP financial measures can be found in the schedules to this release and on our website at www.alcoa.com under the “Invest” section. Alcoa has not provided a reconciliation of any forward-looking non-GAAP financial measures to the most directly comparable GAAP financial measures, due primarily to variability and difficulty in making accurate forecasts and projections, as not all of the information necessary for a quantitative reconciliation is available to the Company without unreasonable effort.

This release does not constitute an offer to sell or the solicitation of an offer to buy any securities. The common shares of the Company to be issued in the Firth Rixson acquisition will only be issued pursuant to the terms of the definitive agreement for the acquisition of Firth Rixson.

Calculation of Financial Measures (unaudited)

(dollars in millions)

Alcoa’s definition of Adjusted EBITDA (Earnings before interest, taxes, depreciation, and amortization) is net margin plus an add-back for 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. Adjusted EBITDA is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because Adjusted EBITDA provides additional information with respect to Alcoa’s operating performance and the Company’s ability to meet its financial obligations. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.

Free Cash Flow is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management reviews cash flows generated from operations after taking into consideration capital expenditures due to the fact that these expenditures are considered necessary to maintain and expand Alcoa’s asset base and are expected to generate future cash flows from operations. It is important to note that Free Cash Flow does not represent the residual cash flow available for discretionary expenditures since other non-discretionary expenditures, such as mandatory debt service requirements, are not deducted from the measure.

Alcoa and subsidiaries

Calculation of Financial Measures (unaudited), continued

(dollars in millions, except per-share amounts)

Net income 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, discrete tax items, and other special items (collectively, “special items”). There can be no assurances that additional special items will not occur in future periods. To compensate for this limitation, management believes that it is appropriate to consider both Net income attributable to Alcoa determined under GAAP as well as Net income attributable to Alcoa – as adjusted.

Days Working Capital = Working Capital divided by (Sales/number of days in the quarter).

Net debt-to-capital is a non-GAAP financial measure. Management believes that this measure is meaningful to investors because management assesses Alcoa’s leverage position after factoring in available cash that could be used to repay outstanding debt.
