"I am proud of our global team's resolve in facing challenges created by the pandemic, focusing first on protecting people," said President and Chief Executive Officer Roy Harvey. "We acted early to implement comprehensive measures to mitigate health risks, and we continue to exercise all precautionary measures to keep people safe and our locations fully operational.

"Despite challenging market conditions, our team has lowered production costs, increased output, maintained stable shipments, and improved our balance sheet. We continued to make progress in executing our strategic actions and 2020 programs, and we finished the quarter with a cash balance of nearly one billion dollars," Harvey continued.

"Earlier this month, we issued corporate bonds at a favorable rate which provides us with improved flexibility as we continue to navigate through the current economic uncertainties," Harvey said. "As we move forward and the economy recovers, we will also be well positioned to complete objectives within our capital allocation framework."

• Shipments: Sequentially, the Company's overall third-party aluminum shipment volume increased approximately 9 percent, primarily due to the continued progress of the Aluminerie de Bécancour Inc. (ABI) smelter in Quebec, Canada restart. Third-party alumina shipments in the second quarter 2020 increased approximately 2 percent, compared with first quarter 2020 shipment volume.
• Revenue: Alcoa reported second quarter 2020 revenue of $2.1 billion, down 10 percent sequentially, primarily due to lower aluminum and alumina prices.
• Net (loss) income attributable to Alcoa Corporation: In the second quarter of 2020, Alcoa reported net loss of $197 million, or $1.06 per share, compared with net income of $80 million, or $0.43 per share, in the first quarter of 2020. The 2020 second quarter results include the net impact of $193 million of special items, including interim tax impacts, costs associated with the curtailment of the Intalco smelter in the state of Washington and the ongoing restart of the ABI smelter. The ABI restart process is expected to be complete during the third quarter 2020.
• Adjusted net loss: Excluding the impact of special items, the second quarter 2020 adjusted net loss was $4 million, or $0.02 per share, improved from the first quarter 2020 adjusted net loss of $42 million, or $0.23 per share.
• Adjusted EBITDA excluding special items: In the second quarter of 2020, Adjusted EBITDA excluding special items was $185 million, a 42 percent sequential decrease primarily attributed to lower aluminum and alumina prices.
• Cash: Alcoa ended the quarter with cash on hand of $965 million and debt of $1.8 billion, for net debt of $836 million. Cash provided from operations in the second quarter of 2020 was $288 million. Cash used for financing activities was $71 million and cash used in investing activities was $79 million.
  Free cash flow was $211 million.
• Working capital: The Company reported 24 days working capital, a 7-day improvement both sequentially and year-over-year, primarily due to fewer receivable days sales outstanding, reflecting progress in the Company's objective to drive year-over-year improvement in working capital.

Strategic Actions and Initiatives

Alcoa is continuing its strategic actions to drive lower costs and sustainable profitability, including the review of its existing production capacities and non-core assets and other cash-preservation programs.

• Intalco Works curtailment
  On April 22, 2020, Alcoa announced the full curtailment at its Intalco Works smelter in Ferndale, Washington. The curtailment of the site's remaining 230,000 metric tons is included in the Company's previously announced review of 1.5 million metric tons of global smelting capacity over a five-year period for potential curtailment, closure, divestiture, or significant improvement. The curtailment is expected to be complete in the third quarter of 2020.
  In the second quarter of 2020, the Company recorded restructuring charges of approximately $27 million (pre- and after-tax) associated with the curtailment, including employee severance and costs associated with termination of contracts. The restructuring charges are all cash-based and are expected to be paid primarily in the third quarter of 2020.
• Spain Collective Dismissal Process
  On June 25, 2020, Alcoa launched a 30-dayformal consultation processwith the Spanish Works Council representing employees at the San Ciprián aluminum facility in Spain, which has incurred significant and recurring financial losses that are expected to continue. The formal consultation began after the conclusion of an informal process that started on May 28, 2020.
  A collective dismissal could potentially affect up to 534 employees at the aluminum plant. The Company envisions a restructuring that retains a portion of the casthouse in operation. No final decisions will be made until the formal consultation process is complete. The San Ciprián site has both an aluminum plant and alumina refinery; the San Ciprián alumina refinery is not affected by this formal consultation process.
• 2020 Programs
  Earlier this year, Alcoa announced 2020 programs to drive leaner working capital and improved productivity. Alcoa intends to improve working capital by $75 to $100 million through reduced inventories and optimized contract terms. Greater productivity and lower costs are expected to result in approximately $100 million of improvements.
• COVID-19Update
  As a result of our comprehensive measures to protect employees, contractors and communities from risks associated with the COVID-19 pandemic, all of our global operations have maintained production without interruption. Globally, approximately 2 percent of the Company's global workforce, including employees and contractors, has been affected by the virus, but most have recovered and have returned to work. The Company's segments have not experienced any significant disruption in its supply sources.
  In the second quarter, the Company experienced a sequential decline in demand for aluminum value- added products, as customers reduced production levels in response to the economic impacts from the pandemic. As a result, Alcoa's production volume was shifted to lower-priced,commodity-grade ingot.
  The Company continues to manage cash during the economic downcycle caused by the pandemic. Those actions include:
• • Utilizing provisions of the U.S. Coronavirus Aid, Relief, and Economic Security (CARES) Act, which provides for both payment deferrals and credits. With these programs, Alcoa expects to defer cash payments for Company pension contributions (approximately $220 million) into 2021 and defer employer payroll taxes (approximately $14 million) into 2021 and 2022.
  • Reducing $100 million of non-critical capital expenditures.

3

• Implementing hiring, travel and other spending restrictions targeted to save or defer approximately $35 million.
• Delaying certain environmental and Asset Retirement Obligations (ARO) spending of $25 million.

Alcoa and Alcoa Foundation continue to support the communities near our operating locations, with special focus on Brazil communities that have been more adversely affected by the pandemic. Alcoa Foundation has pledged more than $1 million to support coronavirus relief efforts in the communities where Alcoa operates through its humanitarian aid program. This is in addition to the almost $3 million the Foundation already committed to grantmaking in communities where we operate, which is being used to provide needed support such as medical supplies, equipment, and food.

Through the combination of the strategic actions, 2020 programs and COVID-19 response actions, Alcoa is on track to save or defer approximately $900 million in cash spend in 2020.

Debt Issuance

On July 8, 2020, Alcoa announced an offering of $750 million aggregate principal amount of 5.500% senior notes due in 2027 (the "notes") by Alcoa Nederland Holding B.V., a wholly-owned subsidiary. The notes increase the Company's overall liquidity and provide for greater flexibility for the Company to execute on strategic actions. The transaction closed on July 13, 2020.

2020 Outlook

The Company's 2020 shipment outlook for Bauxite, Alumina and Aluminum remains unchanged from the prior full-year estimates. Total annual bauxite shipments are expected to range between 48.0 and 49.0 million dry metric tons. Total alumina shipments are projected between 13.6 and 13.7 million metric tons. Aluminum shipments are expected to be between 2.9 and 3.0 million metric tons.

In the third quarter of 2020, Alcoa expects slightly lower quarterly results in the Bauxite segment primarily due to lower volume. In the Alumina segment, the Company expects lower quarterly results from higher energy costs in Australia. In the Aluminum segment, the Company expects improved results with lower raw material costs including energy.

Alcoa is lowering its annual outlook for depreciation, depletion and amortization expense to $665 million from $685 million as favorable currency rates resulted in lower expense in the first half of 2020, as well as lower capital spending in the year. The Company is increasing its expected interest expense for full year 2020 to approximately $150 million from a prior range of $125 to $130 million due to the debt issuance.

As Alcoa's profit before taxes is lower in the current economic environment, the annual operational tax rate can fluctuate significantly. Consequently, the Company is providing an operational tax expense range rather than a rate; third quarter 2020 operational tax expense is expected to approximate $150 million, based on recent pricing.

The COVID-19 pandemic is ongoing, and its magnitude and duration continue to be unknown. The uncertainty around its future impact on the Company's business, financial condition, operating results, and cash flows could cause actual results to differ from this outlook.

Alcoa will hold its quarterly conference call at 5 p.m. Eastern Daylight Time (EDT) on Wednesday, July 15, 2020, to present second quarter financial results and discuss the business and market conditions.

Non-GAAP Financial Measures

Some of the information included in this release is derived from Alcoa Corporation's consolidated financial information but is not presented in Alcoa Corporation'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 regulations. Alcoa Corporation believes that the presentation of non-GAAP financial measures is useful to investors because such measures provide both additional information about the operating performance of Alcoa Corporation and insight on the ability of Alcoa Corporation to meet its financial obligations by adjusting the most directly comparable GAAP financial measure for the impact of, among others, "special items" as defined by the Company, non-cash items in nature, and/or nonoperating expense or income items. The presentation of non-GAAP financial measures is not intended to be a substitute for, and should not be considered in isolation from, the financial measures reported in accordance with GAAP. 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.

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

1. Production amounts can vary from total shipments due primarily to differences between the equity allocation of production and off-take agreements with the respective equity investment.
2. Alcoa Corporation'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. The Adjusted EBITDA presented may not be comparable to similarly titled measures of other companies.

11

1. The Aluminum segment's third-party aluminum shipments are composed of both primary aluminum and flat-rolled aluminum.
2. Transformation includes, among other items, the Adjusted EBITDA of previously closed operations.
3. Corporate expenses are composed of general administrative and other expenses of operating the corporate headquarters and other global administrative facilities, as well as research and development expenses of the corporate technical center.
4. Other includes certain items that impact Cost of goods sold and Selling, general administrative, and other expenses on Alcoa Corporation's Statement of Consolidated Operations that are not included in the Adjusted EBITDA of the reportable segments, including those described as "Other special items" (see footnote 1 to the reconciliation of Adjusted Income within Calculation of Financial Measures included in this release).

Corporation - as adjusted	$	(4)	$	(42)	$	(2)	$	(0.02)	$	(0.23)	$	(0.01)

Net loss attributable to Alcoa Corporation - as adjusted is a non-GAAP financial measure. Management believes this measure is meaningful to investors because management reviews the operating results of Alcoa Corporation excluding the impacts of restructuring and other charges, various 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 it is appropriate to consider both Net (loss) income attributable to Alcoa Corporation determined under GAAP as well as Net loss attributable to Alcoa Corporation - as adjusted.

1. Other special items include the following:
2. • For the quarter ended June 30, 2020, costs related to the restart process at the Bécancour, Canada smelter ($17), external costs related to portfolio actions ($1), and a net favorable change in certain mark-to-market energy derivative instruments ($3);
   • for the quarter ended March 31, 2020, a gain on the sale of a waste treatment facility in Gum Springs, Arkansas ($180), costs related to the restart process at the Bécancour, Canada smelter ($32), and a net unfavorable change in certain mark-to-market energy derivative instruments ($11); and,
   • for the quarter ended June 30, 2019, costs related to union negotiations in the U.S. ($5), costs related to a work stoppage at the Bécancour, Canada smelter ($2), and costs related to a collective employee dismissal process in Spain at the Avilés and La Coruña smelters ($1).
3. Discrete tax items and interim tax impacts are the result of discrete transactions and interim period tax impacts based on full-year assumptions and include the following:
4. • for the quarter ended June 30, 2020, a net charge of interim tax impacts ($142);
   • for the quarter ended March 31, 2020, a net charge of interim tax impacts ($21) and a net charge of several other items ($1); and,
   • for the quarter ended June 30, 2019, a net charge of interim tax impacts ($31) and a net charge of several other items ($1).
5. The tax impact on special items is based on the applicable statutory rates in the jurisdictions where the special items occurred. The noncontrolling interest impact on special items represents Alcoa's partner's share of certain special items.
6. In any given period, the average number of shares applicable to diluted EPS for Net (loss) income attributable to Alcoa Corporation common shareholders may exclude certain share equivalents as their effect is anti-dilutive. However, certain of these share equivalents may become dilutive in the EPS calculation applicable to Net loss attributable to Alcoa Corporation common shareholders - as adjusted due to a larger and/or positive numerator. Specifically, for all periods presented, the average number of share equivalents applicable to diluted EPS - as adjusted had an anti-dilutive effect, and therefore, are excluded from the diluted EPS calculation.

Alcoa's Corporation'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 this measure is meaningful to investors because Adjusted EBITDA provides additional information with respect to Alcoa Corporation'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.

1. Special items include the following (see reconciliation of Adjusted Income above for additional information):
2. • for the quarter ended June 30, 2020, costs related to the restart process at the Bécancour, Canada smelter ($17) and external costs related to portfolio actions ($1);
   • for the quarter ended March 31, 2020, costs related to the restart process at the Bécancour, Canada smelter ($32); and,
   • for the quarter ended June 30, 2019, costs related to union negotiations in the U.S. ($5), costs related to a work stoppage at the Bécancour, Canada smelter ($2), and costs related to a collective employee dismissal process in Spain at the Avilés and La Coruña smelters ($1).

Capital expenditures		(77)		(91)		(89)
Free cash flow	$	211	$	(181)	$	(7)

Free Cash Flow is a non-GAAP financial measure. Management believes this measure is meaningful to investors because management reviews cash flows generated from operations after taking into consideration capital expenditures, which are both necessary to maintain and expand Alcoa Corporation's asset base and 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.

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