4Q 2014 Highlights

4Q 2014 Transformation Highlights

Full-Year 2014 Highlights

New York, Jan. 12, 2015 – Lightweight metals leader Alcoa (NYSE:AA) today reported a jump in fourth quarter and full-year 2014 profits, culminating a year of significant transformation for the Company. Alcoa is reshaping its portfolio for profitable growth by building its innovative, multi-material value-add businesses and by creating a globally competitive commodity business.

In fourth quarter 2014, Alcoa reported net income of $159 million, or $0.11 per share, which includes $273 million in special items largely tied to previously announced restructurings in the upstream and midstream businesses, aligned with the Company’s objective of enhancing its portfolio.

Year-over-year, fourth quarter 2014 results are up from a net loss of $2.3 billion, or $2.19 per share. Excluding the impact of special items, fourth quarter 2014 net income was $432 million, or $0.33 per share, which rose significantly from fourth quarter 2013 net income of $40 million, or $0.04 per share.

Fourth quarter 2014 revenue was $6.4 billion, up 14 percent from $5.6 billion in fourth quarter 2013. Higher sales in Alcoa’s value-add businesses, comprising the mid and downstream, favorable metal prices and energy sales drove the Company’s year-over-year revenue increase.

“Our strong fourth quarter capped a pivotal year as we significantly accelerated Alcoa’s transformation,” said Klaus Kleinfeld, Alcoa Chairman and Chief Executive Officer. “As we built out our value-add businesses, we gained profitable share across exciting downstream growth markets and captured aerospace and automotive growth in the midstream. On the commodity side, our hard work reshaping the portfolio continues to pay off with improved performance for the 13th quarter in a row. In 2014 we delivered Alcoa’s strongest operating results since 2008; we enter 2015 on solid footing, poised to continue transforming and growing.”

Engineered Products and Solutions reported its 19th consecutive quarter of year-over-year after-tax operating income growth, excluding Firth Rixson. Global Rolled Products continued to benefit from the historic shift to aluminum intensive vehicles, shipping a record volume of automotive sheet. In Global Primary Products, comprising Alumina and Primary Metals, the Alumina segment’s profitability more than doubled year-over-year. Primary Metals adjusted EBITDA per metric ton was the strongest since second quarter 2008, primarily reflecting a lower cost, globally competitive commodity business.

Special items in fourth quarter 2014 included $200 million in restructuring-related costs, approximately 80 percent non-cash, primarily tied to the sales of three European rolling mills (see Value-add Portfolio Transformation below) and an ownership stake in a bauxite mining and alumina refining joint venture in Jamaica (see Upstream Portfolio Transformation below).

2014 Full-Year Results

In 2014, Alcoa reported net income of $268 million, or $0.21 per share, compared to a net loss of $2.3 billion, or $2.14 per share, in 2013.

Excluding the impact of special items, strong performance growth drove 2014 net income of $1.1 billion, or $0.92 per share, up slightly more than threefold from 2013 net income of $357 million, or $0.33 per share. Revenue in 2014 was $23.9 billion, up 4 percent from $23 billion in 2013.

In 2014, Alcoa continued to execute against its financial targets. The Company achieved $1.2 billion productivity savings, exceeding an $850 million annual target; managed growth capital expenditures of $484 million against a $500 million annual target and controlled sustaining capital expenditures of $735 million against a $750 million annual target. Progress on the Saudi Arabia joint venture project remained on track with $91 million invested in 2014 against a $125 million annual target.

For full-year 2014, Alcoa delivered $455 million in positive free cash flow. The Company produced $989 million of free cash flow in fourth quarter 2014, the highest since fourth quarter 2010.

For full-year 2014, Alcoa’s cash from operations totaled $1.7 billion. In fourth quarter 2014, the Company’s cash from operations was $1.5 billion, a quarterly record.

Fourth quarter average days working capital held steady year-over-year at 28 days. The Company has reduced average days working capital by 9 days since 2009.

The Company’s debt totaled $8.9 billion at the end of 2014, with cash on hand of $1.9 billion. Alcoa’s debt-to-capital ratio stood at 37.4 percent, with net debt-to-capital at 32 percent.

Value-add Portfolio Transformation

Alcoa continued to make investments in the fourth quarter to expand its multi-material, innovative value-add portfolio for enhanced profitable growth.

In the downstream, the Company completed the acquisition of jet engine component leader Firth Rixson. With this acquisition, Alcoa’s revenues are expected to increase by $1.6 billion, driving an additional $350 million EBITDA, by 2016, and by $2 billion by 2019. Alcoa also announced plans to purchase TITAL to grow its platform of titanium aerospace components. In 2013, TITAL generated revenues of approximately $100 million, more than half of which came from titanium products. TITAL’s titanium revenues are expected to increase 70 percent by 2019. Alcoa expects to close the transaction in the first quarter 2015.

Additionally, Alcoa is doubling its jet engine coating technology capacity at its Whitehall, Michigan, U.S. facility. Investments in the robust aerospace market further strengthen Alcoa’s global aerospace portfolio to meet growing demand for hotter-running, more fuel-efficient jet engines.

In the midstream, the Company unveiled the Micromill^TM to manufacture the most advanced aluminum sheet on the market. The Micromill’s breakthrough casting technology will enable the next generation of automotive aluminum products and equip Alcoa to capture growing demand from the automotive industry. Automotive parts made with Alcoa Micromill^® material will be twice as formable and 30 percent lighter than parts made from high strength steel.

Alcoa is also reshaping its midstream business to focus on higher growth products and markets. In the fourth quarter, the Company finalized the sale of three European rolling mills, two in Spain and one in France, to a subsidiary of Atlas Holdings LLC. Alcoa also completed the closure of the Point Henry and Yennora, Australia can sheet rolling mills.

Upstream Portfolio Transformation

Alcoa continues to reduce costs in the upstream, making its commodity business increasingly competitive on a global scale.

In the fourth quarter, the Company completed sales of two upstream assets. Alcoa World Alumina and Chemicals sold its 55 percent ownership stake in the Jamalco bauxite mining and alumina refining joint venture to Noble Group Ltd for $140 million. Alcoa also sold its 50.33 percent interest in the Mt. Holly aluminum smelter to Century Aluminum Company for $67.5 million. Alcoa has curtailed, closed or sold 1.3 million metric tons, or 31 percent, of its highest cost global smelting capacity since 2007.

In Saudi Arabia, the Ma’aden-Alcoa joint venture refinery is fully operational and produced its first alumina in the fourth quarter from Saudi Arabian bauxite. The smelter is fully operational and profitable.

Investing in the world’s lowest-cost aluminum complex and divesting, or closing, high cost capacity supports the Company’s goal to create a globally competitive commodity business. Alcoa aims to lower its position on the world aluminum production cost curve to the 38^th percentile and the global alumina cost curve to the 21^st percentile by 2016.

2015 End Market Projections

Alcoa projects another strong year for global aerospace sales. The Company expects 2015 global aerospace sales to increase 9 to 10 percent over 2014, on continued robust demand for large commercial aircraft, regional jets and jet engines. For automotive, the Company projects steady growth to continue in 2015. Alcoa forecasts global automotive production of 2 to 4 percent driven by replacement demand and low lending rates in North America and both the growth of the middle class and clean air regulations in China.

Alcoa projects stable 2015 global commercial transportation production of negative 1 to positive 3 percent. After a strong 2014, the trucking market in North America is expected to remain positive in 2015 with production growth of 3 to 7 percent on strong orders and freight growth. In the packaging market, Alcoa projects global sales growth of 2 to 3 percent in 2015.

Alcoa expects the building and construction market to continue to improve from 2014 with 2015 global sales growth of 5 to 7 percent. The North American market is expected to sustain its gradual recovery in 2015, while the European market is likely to remain in decline.

In the industrial gas turbine market, the Company projects a 1 to 3 percent growth rate in 2015, rebounding from a decline in 2014. The airfoil market is expected to improve as original equipment manufacturers develop new, advanced turbines and upgrade existing turbines.

Alcoa sees global aluminum demand growth of 7 percent in 2015, following 7 percent growth in 2014.

Segment Information

Engineered Products and Solutions

ATOI in the fourth quarter was $165 million, compared to $209 million in third quarter 2014, and down $3 million or 2 percent year-over-year, including a Firth Rixson integration impact of $12 million. Excluding that impact, ATOI was a fourth quarter record and the 19th consecutive quarter of year-over-year ATOI growth; continued productivity gains and higher volumes drove the improvement, mostly offset by cost increases and unfavorable mix. This segment reported a fourth quarter adjusted EBITDA margin of 18.9 percent compared to 20.3 percent for the same quarter last year; excluding Firth Rixson, adjusted EBITDA margin performance of 20.6 percent was a fourth quarter record.

Global Rolled Products

ATOI in the fourth quarter was $71 million compared to $103 million in third quarter 2014, and $21 million in fourth quarter 2013. The segment had record automotive sheet shipments, resulting from the Davenport expansion. From the prior year, this segment increased profits by 238 percent, mainly driven by strong productivity, higher metal prices, and higher volume in North American

automotive and aerospace. Results were partially offset by cost increases from deferred maintenance, automotive ramp-up, increased regional premiums in Russia and Europe as well as pricing pressure in the packaging and European industrial markets. The segment will continue to increase production in the first quarter to serve growing demand for aluminum intensive vehicles.

Alumina

ATOI in the fourth quarter was $178 million, up $116 million sequentially from $62 million, and up $108 million year-over-year from $70 million. The increase in sequential ATOI was primarily due to higher pricing on both Alumina Price Index and London Metal Exchange-based contracts, favorable foreign currency exchange rates and energy costs, and increased productivity. Results were slightly offset by higher pre-operational costs at the Saudi Arabia refinery and maintenance costs. Adjusted EBITDA per metric ton increased $39 from third quarter 2014 to $85 per metric ton in fourth quarter 2014.

Primary Metals

ATOI in the fourth quarter was $267 million, up $22 million sequentially from $245 million, and up $302 million from negative $35 million in fourth quarter 2013. Third-party realized price in fourth quarter 2014 was $2,578 per metric ton, up 2 percent sequentially, and up 20 percent year-over-year. Improved sequential earnings were driven by higher realized prices, the absence of charges in the third quarter related to previously announced smelter closures in Italy and Australia, favorable foreign currency exchange rates, increased productivity and the ramp up of the Saudi Arabia smelter. Results were partially offset by higher power costs, primarily in Spain, and higher materials costs. Adjusted EBITDA per metric ton was $629, $17 per metric ton higher than third quarter 2014.

Alcoa will hold its quarterly conference call at 5:00 PM Eastern Time on January 12, 2015 to present the quarter and full-year results. The meeting will be webcast via alcoa.com. Call information and related details are available at www.alcoa.com under “Invest.” Presentation materials used during this meeting will be available for viewing at 4:15 PM Eastern Time at www.alcoa.com.

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.

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.

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 (loss) 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.
