Business Update

Coronavirus

In response to the ongoing coronavirus (COVID-19) pandemic, Alcoa implemented
comprehensive measures to protect the health of the Company's workforce, prevent
infection in our locations, mitigate impacts, and safeguard business continuity.
As a result of these measures and the aluminum industry being classified as an
essential business, all of Alcoa's bauxite mines, alumina refineries, and
aluminum manufacturing facilities continue to remain in operation. The Company
continues, through its operations leadership team and global crisis response
team, to ensure that each location's preparedness and response plans are up to
date.

The Company has not experienced any significant interruption from its supply
sources, and the Company's locations have had minimal contractor- and
employee-related disruptions to date. The magnitude and duration of the COVID-19
pandemic is unknown. The pandemic could have adverse future impacts on the
Company's business, financial condition, operating results, and cash flows.
Further adverse conditions or prolonged deterioration of conditions could
negatively impact our financial condition and result in asset impairment
charges, including long-lived assets or goodwill, or affect the realizability of
deferred tax assets.

As a result of the pandemic's impact on the macroeconomic environment,
management evaluated the future recoverability of the Company's assets,
including goodwill and long-lived assets, and the realizability of deferred tax
assets while considering the Company's current market capitalization. Management
concluded that no asset impairments and no additional valuation allowances were
required through March 31, 2021.

Key Actions



On November 30, 2020, the Company entered into an agreement to sell its rolling
mill located at Warrick Operations (Warrick Rolling Mill), an integrated
aluminum manufacturing site near Evansville, Indiana (Warrick Operations), to
Kaiser Aluminum Corporation (Kaiser). On March 31, 2021, the Company completed
the sale for total consideration of approximately $670, which includes the
assumption of $72 in other postretirement benefit liabilities (subject to
further post-closing adjustments). Additionally, as of March 31, 2021, the
Company incurred transaction costs of $7 and capital expenditures of $8 related
to site separation. The Company recorded a gain of $27 in Other income, net
(pre- and after-tax) on the Statement of Consolidated Operations upon closure.
The consideration and gain amounts are subject to customary post-closing
adjustments. Alcoa retains ownership of the site's 269 kmt aluminum smelter and
its electricity generating units at Warrick Operations with a market-based metal
supply agreement with Kaiser. In addition to the $15 in spend noted above, in
the first quarter of 2021 the Company recorded estimated liabilities of
approximately $70 for future site separation commitments and remaining
transaction costs associated with the sales agreement. Approximately half of the
obligation is expected to be spent in 2021, with the remainder to be spent in
2022 and 2023. Additionally, the Company expects to incur $5 of additional
capital expenditures for assets required for the Company to separately operate
its portion of the site.

In March 2021, ANHBV, a wholly-owned subsidiary of Alcoa Corporation, issued
$500 aggregate principal amount of 4.125% Senior Notes due 2029 (the 2029 Notes)
in a private transaction exempt from the registration requirements of the
Securities Act of 1933, as amended (the Securities Act). The net proceeds of
this issuance were approximately $493 reflecting a discount to the initial
purchasers of the 2029 Notes, as well as issuance costs. The Company used the
proceeds, together with cash on hand, to contribute $500 to its U.S. defined
benefit pension plans applicable to salaried and hourly employees on April 1,
2021, and to redeem in full $750 aggregate principal amount of the Company's
outstanding 6.75% Senior Notes due 2024 (the 2024 Notes) on April 7, 2021, and
to pay transaction-related fees and expenses.

On March 18, 2021, the Company signed 5-year agreements to repower the Portland
Aluminum Smelter in the State of Victoria, Australia. The agreements with three
separate providers will commence on August 1, 2021. Further, the Australian
Federal Government has committed, subject to approval, to provide up to $15
(A$19) per year for four years to underwrite the smelter's participation in the
Reliability and Emergency Reserve Trader (RERT) scheme. The arrangement will
recognize the smelter's ability to rapidly shed load when required to help
protect the power grid from unexpected interruptions when it is under duress.

See the below sections for additional details on the above described actions.

Spain Matters

In January 2021, the Company reached an agreement with the workers' representatives to temporarily suspend the labor strike at its San Ciprián alumina refinery and aluminum smelter in Spain through April 30, 2021 (subsequently extended through May 11, 2021). As part of the agreement, the Company agreed to conduct an exclusive sale process with Sociedad Estatal de Participaciones Industriales (SEPI), a Spanish government-owned entity. The Company has complied with the terms of the agreement to pursue a sale, has delivered a term sheet to SEPI, and is continuing to evaluate potential solutions.



The refinery and smelter have continued operations and the Company remains open
to an agreement to further extend the strike suspension period. Although the
ultimate outcome is currently unknown, the reactivation of the strike may
negatively affect the Company's operating and financial results due to reduced
refinery production and metal shipments.

During 2019, the Company completed the divestiture of the Avilés and La Coruña
(Spain) aluminum facilities to PARTER Capital Group AG (PARTER) in a sale
process endorsed by the Spanish government and supported by the workers'
representatives following a collective dismissal process. In 2020, PARTER sold
its majority stake in the facilities to an unrelated party. The Company had no
knowledge of the subsequent transaction prior to its announcement, and has filed
a lawsuit asserting that the sale was in breach of the sale agreement between
Alcoa and PARTER.

Related to this divestiture, certain claims and investigations have been
initiated by or at the request of the employees of the facilities against their
current employers, the owners of the current employers, and Alcoa, alleging that
the agreements of the collective dismissal process remain in force and that
Alcoa remains liable for related social benefits to the employees. The Company
continues to believe it acted in good faith, in full compliance with the law and
the agreements, with the endorsement of the Spanish government, and with the
support of the workers' representatives throughout the sale process.

Results of Operations



In accordance with the recently adopted amendments to Item 303 of Regulation
S-K, Management has updated its comparison of interim periods to compare the
results of the most recent quarter against the results of the immediately
preceding sequential quarter in an effort to provide a more meaningful analysis
as we are not a seasonal business and to align the discussion with how
management reviews the results of the Company. The Company will continue to
present a comparison of the most recent year-to-date period and the
corresponding year-to-date period of the preceding fiscal year.

Segment Information

Alcoa Corporation is a producer of bauxite, alumina, and aluminum products. The
Company's operations consist of three worldwide reportable segments: Bauxite,
Alumina, and Aluminum. Segment performance under Alcoa Corporation's management
reporting system is evaluated based on a number of factors; however, the primary
measure of performance is the Adjusted EBITDA (Earnings before interest, taxes,
depreciation, and amortization) of each segment. The Company calculates Segment
Adjusted EBITDA as Total sales (third-party and intersegment) minus the
following items: Cost of goods sold; Selling, general administrative, and other
expenses; and Research and development expenses. Alcoa Corporation's Adjusted
EBITDA may not be comparable to similarly titled measures of other companies.

Bauxite



Business Update. During the first quarter, the segment realized lower internal
bauxite pricing and lower earnings from minority owned mines. Further, the
Company successfully relocated the Willowdale mining operations to the next
planned location in the Darling range and operations have resumed. Additional
costs to finalize the move are anticipated through the third quarter of 2021.
The segment incurred higher depreciation expense in the first quarter related to
these mine moves.

Production in the below table can vary from Total shipments due primarily to
differences between the equity allocation of production and off-take agreements
with the respective equity investment. Operating costs in the table below
includes all production-related costs: conversion costs, such as labor,
materials, and utilities; depreciation, depletion, and amortization; and plant
administrative expenses.

Forward Look. For the second quarter of 2021, operations are expected to be consistent with the first quarter of 2021.

Alumina

Business Update. During the first quarter of 2021, the average API trended favorably, showing a 7% and 10% improvement over the first and fourth quarters of 2020, respectively. The alumina segment also experienced lower internal bauxite costs which were partially offset by higher energy costs in both periods.



At March 31, 2021, the Alumina segment had base capacity of 12,759 kmt with 214
kmt of curtailed refining capacity. There were no changes to base or curtailed
capacity during 2020 or through the first three months of 2021.

Total shipments include metric tons that were not produced by the Alumina
segment. Such alumina was purchased to satisfy certain customer commitments. The
Alumina segment bears the risk of loss of the purchased alumina until control of
the product has been transferred to this segment's customer. Additionally,
operating costs in the table below includes all production-related costs: raw
materials consumed; conversion costs, such as labor, materials, and utilities;
depreciation and amortization; and plant administrative expenses.

                                               Australian dollar)

Forward Look. For the second quarter of 2021 in comparison with the first quarter, we expect stable operations with higher production costs due to seasonal maintenance and energy costs.

Aluminum



Business Update. During the first quarter, metal prices increased and shipments
remained strong, including improved demand for value-add products. The
suspension of the labor strike at the San Ciprián smelter resulted in higher
sales volumes from metal shipments that had been blocked during the strike.

Total aluminum third-party shipments and total primary aluminum shipments
include metric tons that were not produced by the Aluminum segment. Such
aluminum was purchased by this segment to satisfy certain customer commitments.
The Aluminum segment bears the risk of loss of the purchased aluminum until
control of the product has been transferred to this segment's customer. Total
aluminum information includes flat-rolled aluminum while Primary aluminum
information does not. Operating costs includes all production-related costs: raw
materials consumed; conversion costs, such as labor, materials, and utilities;
depreciation and amortization; and plant administrative expenses.

The average realized third-party price per metric ton of primary aluminum
includes three elements: a) the underlying base metal component, based on quoted
prices from the LME; b) the regional premium, which represents the incremental
price over the base LME component that is associated with the physical delivery
of metal to a particular region (e.g., the Midwest premium for metal sold in the
United States); and c) the product premium, which represents the incremental
price for receiving physical metal in a particular shape (e.g., billet, slab,
rod, etc.) or alloy.

(1) These figures represent Alcoa Corporation's share of the facility Nameplate

Capacity based on its ownership interest in the respective smelter.

(2) On April 22, 2020, Alcoa announced the curtailment of the remaining 230 kmt

of smelting capacity at the Intalco smelter. The full curtailment of 279

kmt, which includes 49 kmt of earlier-curtailed capacity, was completed


     during the third quarter of 2020.


(3)  Curtailed capacity at the Bécancour (Canada) smelter decreased by 49 kmt
     from the first quarter 2020 to the first quarter 2021 as a result of the

restart process. The restart completed during the third quarter of 2020.




Forward Look. For the second quarter of 2021 in comparison to the first quarter,
we expect sustained strong shipments and demand for value-add products,
partially offset by unfavorable impacts from the absence of the Warrick Rolling
Mill results, lower hydro sales from a seasonal decline in market prices,
unfavorable impacts from current energy market conditions, and higher seasonal
maintenance.
