Alcoa Reports Strong First Quarter 2014 Results

Offset by Special Items as Portfolio Transformation Accelerates

1Q 2014 Financial Highlights

1Q 2014 Portfolio Transformation Highlights

New York, April 8, 2014 – Alcoa (NYSE:AA) today reported strong quarterly results offset by special items tied to restructuring as the Company’s transformation accelerates.

In first quarter 2014, Alcoa reported a net loss of $178 million, or $0.16 per share, which includes $276 million in special items largely tied to smelter and rolling mill capacity reductions. Excluding the impact of special items, net income was $98 million, or $0.09 per share. Alcoa’s value-add businesses drove 76 percent of segment profits in first quarter 2014, with record first quarter results in Engineered Products and Solutions and a near three-fold sequential increase in profitability in Global Rolled Products. Alumina reported the best quarterly after-tax operating income (ATOI) since 2011 and the combined upstream segments have improved operating performance for the 10^th consecutive quarter.

“We hit record downstream profitability, nearly tripled results in the midstream, and strengthened our upstream business for the 10^th quarter in a row,” said Klaus Kleinfeld, Alcoa Chairman and Chief Executive Officer. “Our transformation is accelerating – we’re powering growth in our value-add businesses and aggressively reshaping our commodity business.”

First quarter 2014 revenues were $5.5 billion, down 2 percent sequentially on lower Primary Metals third-party shipments. Capacity reductions in Primary Metals combined with an 8 percent decline in year-over-year realized aluminum prices caused revenues to fall 6 percent from the first quarter last year. The Company’s value-add businesses drove 58 percent of Alcoa’s first quarter revenues.

Sequentially, first quarter 2014 results compare to a net loss of $2.3 billion, or $2.19 per share, in fourth quarter 2013. Excluding special items, first quarter 2014 results compare to net income of $40 million, or $0.04 per share, in the sequential period.

Year-over-year, first quarter 2014 results compare to net income of $149 million, or $0.13 per share, in first quarter 2013. Excluding special items, first quarter 2014 net income compares to $121 million, or $0.11 per share, in the year-ago period when realized aluminum prices per metric ton were $193 higher.

Continued Growth Across End Markets

Alcoa is increasing its 2014 global aerospace growth expectation by one percentage point (8 percent to 9 percent, previously 7 percent to 8 percent), on strong demand for both large commercial aircraft and regional jets and continued growth in the business jet market. The Company also continues to project 2014 growth in automotive (1 percent to 4 percent), packaging (2 percent to 3 percent), and building and construction (4 percent to 6 percent). Alcoa expects a steady commercial transportation market (-1 percent to 3 percent) and a decline in the industrial gas turbine market (-8 percent to -12 percent) on lower orders for new gas turbines and spare parts.

Alcoa continues to project 7 percent global aluminum demand growth in 2014.

Value-Add Portfolio Transformation

Alcoa continued to build out its value-add businesses in the first quarter by introducing innovative new products, investing in high-value expansions, and optimizing its rolling mill portfolio.

Within Engineered Products and Solutions (EPS), the Company’s downstream business, Alcoa introduced the world’s lightest heavy-duty truck wheel. The Ultra ONE™ is based on Alcoa’s newest and strongest aluminum wheel alloy, MagnaForce™. The 40-pound wheel weighs 47 percent less than comparable steel wheels, and can help save 1,400 pounds per rig for increased payload and better gas mileage. Over 150 fleets are specifying 67,000 Ultra ONE™ wheels since they were introduced.

In Hungary, Alcoa is investing $13 million in its wheel plant in Székesfehérvár to meet rising European demand for its Dura-Bright^® surface-treated wheels. The expansion will enable Alcoa to produce twice as many Dura-Bright^® surface-treated wheels in Europe by early 2015, compared with current production levels.

These portfolio enhancements support EPS’ three-year goal of generating $1.2 billion in incremental revenue growth by 2016, with $900 million coming from share gains and innovations.

Within Global Rolled Products (GRP), the Company’s midstream business, Alcoa announced a $40 million investment in its Itapissuma, Brazil rolling mill to increase production of specialty foils for aseptic and flexible packaging, the most highly differentiated type of container in packaging. To further improve the profitability of the rolling mill business, Alcoa will also close its two rolling mills in Australia by year-end. The mills serve the Australian and Asian can sheet markets, which have been impacted by excess capacity.

As demand for automotive sheet in North America ramps up, Alcoa commissioned the $300 million expansion at its Davenport, Iowa facility, and it is now fully operational. Progress continues on the automotive expansion at Alcoa, Tennessee, and the rolling mill at the Ma’aden-Alcoa joint venture is expected to produce the first auto coil in the fourth quarter of this year. Alcoa projects that the added capacity in Iowa and Tennessee alone will grow auto sheet revenues six fold from 2013 to over $1.3 billion in 2018.

These actions in the midstream will further optimize GRP’s mill portfolio and support its goal of generating $1.0 billion in incremental revenue growth by 2016, with $900 million through share gains and innovations.

Upstream Portfolio Transformation

In the upstream, Alcoa is taking aggressive action to lower the cost base of its commodity business and announced three smelting capacity reductions in the first quarter:

Once all announced curtailments and closures are executed, Alcoa will have reduced operating smelting capacity by 1.2 million metric tons, or 28 percent, since 2007.

Alcoa’s review of its Primary Metals operations is consistent with the Company’s goal of lowering its position on the world aluminum production cost curve to the 38^th percentile by 2016.

Financial Performance

Alcoa achieved $250 million in year-over-year productivity gains against an $850 million annual target, driven by process improvements and procurement savings across all businesses. Alcoa managed growth capital expenditures of $92 million against a $500 million annual target and controlled sustaining capital expenditures of $117 million against a $750 million annual plan. Expenditures on the Saudi Arabia joint venture project were on track at $35 million invested against a $125 million annual plan.

Free cash flow for the quarter was negative $760 million, with cash used for operations of $551 million, driven by the normal build in working capital, semi-annual interest payments, and pension contributions. Alcoa ended the quarter with cash on hand of $665 million.

The Company achieved an average of 30 days working capital for the quarter, two days lower than first quarter 2013, equal to approximately $120 million cash and the 18^th consecutive quarter of improvement in year-over-year average days working capital. Sequentially, average days working capital is two days higher due to normal inventory build in the first quarter.

In first quarter 2014, holders of $575 million principal amount of Alcoa’s 5.25% Convertible Notes due March 15, 2014 exercised their option to convert the Notes into shares of Alcoa common stock. As a result, the Company reduced its debt from $8.3 billion in fourth quarter 2013 to $7.7 billion in first quarter 2014, with net debt of $7.1 billion. Alcoa’s debt-to-capital ratio stood at 35.0 percent, while net debt-to-capital ratio stood at 33.0 percent.

Segment Performance

Engineered Products and Solutions

ATOI was a first quarter record of $189 million, up $21 million, or 13 percent, sequentially and up $16 million, or 9 percent, year-over-year. Higher volumes in aerospace and commercial transportation combined with favorable productivity across all businesses drove the improvement sequentially and year-over-year. This segment reported a record first quarter adjusted EBITDA margin of 22.2 percent, compared to 20.9 percent in the same quarter last year.

Global Rolled Products

ATOI in the first quarter was $59 million, including a charge of $11 million related to the permanent shutdown of the Australia rolling operations. First quarter 2014 ATOI is up from $21 million in fourth quarter 2013, and down from $81 million in first quarter 2013. Sequentially, ATOI almost tripled on record auto sheet quarterly revenue, strengthening demand in industrial and commercial transportation products, favorable productivity and fixed cost absorption from higher mill utilization partially offset by pricing and volume pressures in packaging. Adjusted EBITDA per metric ton, excluding the impact of the shutdown of the Australia rolling operations, was $342.

Alumina

ATOI in the first quarter was $92 million, up $22 million sequentially, a 31 percent improvement, and up $34 million year-over-year, a 59 percent improvement. Positive Alumina Price Index/spot pricing, the sale of our Suriname gold mine interest, and continued productivity improvements drove the sequential increase, mostly offset by lower London Metal Exchange (LME) pricing, lower volume due to fewer days in the quarter, and increases in some input costs. Adjusted EBITDA per metric ton rose $3 from fourth quarter 2013 to $49, the highest since fourth quarter 2011, reflecting the impact of improving operations, cost focus, and Alumina Price Index and spot pricing.

Primary Metals

ATOI in the first quarter was negative $15 million, up from negative $35 million sequentially, and down from $39 million in first quarter 2013. Third-party realized price in the first quarter was $2,205 per metric ton, up 2 percent sequentially, but down 8 percent year-over-year. Sequential results were driven by higher regional premiums, value-add product mix improvements, and favorable energy prices, partially offset by negative LME impacts, higher alumina costs and taxes, as well as costs related to smelter closures at the Point Henry and Massena East smelters. Adjusted EBITDA per metric ton was $150, $63 per metric ton higher than fourth quarter 2013.

Alcoa will hold its quarterly conference call at 5:00 PM Eastern Daylight Time on April 8, 2014 to present quarterly results. The meeting will be webcast via alcoa.com. Call information and related details are available at www.alcoa.com under “Invest.”

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.
