Alcoa Signs Long-Term Supply Agreement with Spirit AeroSystems for Aluminum Sheet

May 1, 2014

Announcement Reinforces Company’s 8-9% Global Aerospace Growth Expectation

Alcoa (NYSE:AA), the global leader in aerospace sheet and plate
products, today announced it has signed a long-term agreement to supply
aluminum sheet to Spirit AeroSystems, Inc. in a contract valued at
approximately $290 million over five years. On April 8, Alcoa increased
its 2014 global aerospace growth expectation by one percentage point to
8 percent to 9 percent, on strong demand for both large commercial
aircraft and regional jets and continued growth in the business jet
market.

“Alcoa produces lightweight metallic solutions for the aerospace
industry that deliver strength, aerodynamic efficiencies, and corrosion
resistance,” said Mark Vrablec, President, Global Aerospace,
Transportation and Industrial Rolled Products at Alcoa. “This new
multi-year contract with Spirit deepens our collaborative relationships
and enables us to continue to grow in this important market. We are
well-established in the aerospace industry and offer the best value and
performance to our customers.”

Spirit is one of the largest designers and manufacturers of
aerostructures for commercial, military, business and regional jets in
the world.

Alcoa will provide Spirit with aluminum sheet products for fuselage
skins from its Davenport (Iowa) facility, which houses the world’s
largest and most advanced aluminum rolling mill.

Alcoa’s aerospace business, which had revenues totaling $4 billion in
2013, holds leading market positions in aerospace forgings, extrusions,
jet engine airfoils and fastening systems produced by its downstream
business, Engineered Products and Solutions (EPS), and aerospace sheet
and plate produced by its midstream business, Global Rolled Products
(GRP). The Company’s value-add businesses, comprising EPS and GRP,
accounted for 58 percent of Alcoa’s first quarter 2014 revenues and 76
percent of the Company’s total segment after-tax operating income.
