Alcoa Signs Bauxite Supply Contracts Worth More Than $350 Million

April 6, 2016

Multiple contracts will more than double Alcoa’s third-party bauxite sales in 2016

Alcoa (NYSE:AA), the world’s largest bauxite miner, today announced that
Alcoa World Alumina and Chemicals (AWAC) has secured multiple bauxite
supply contracts valued at more than $350 million over the next two
years. Under the contracts, the Company will supply bauxite to external
customers from three of its global mines as it continues to successfully
build its third-party bauxite business. The new contracts cover
customers in China, Europe and Brazil.

“With our quality resources and deep technical expertise, we are well
positioned to deliver a stable supply of bauxite to customers across the
global alumina industry,” said Garret Dixon, president of Alcoa Mining.
“Our strategy is to profitably grow our third-party bauxite sales and
these contracts demonstrate that we are well on track.”

Alcoa is the world’s largest bauxite miner, with 45.3 million bone dry
metric tons of production in 2015. Alcoa has ownership in seven active
bauxite mines globally, four of which are operated by the Company. These
mines are strategically located near key Atlantic and Pacific markets,
including the Huntly mine in Australia, the second largest bauxite mine
in the world.

The AWAC group of companies is owned 60 percent by Alcoa and 40 percent
by Alumina Limited of Australia.

As previously announced, Alcoa will separate into two, industry-leading
publicly traded companies in the second half of 2016. The Upstream
Company will comprise the five business units that today make up Global
Primary Products: Bauxite, Alumina, Aluminum, Cast Products and Energy.
The Value-Add company, to be named Arconic, will include the Global
Rolled Products, Engineered Products and Solutions, and Transportation
and Construction Solutions businesses.
