• Alcoa Rolled Products content now on every Boeing platform
• Largest contract ever between the two companies
• Companies will work together on developing new, innovative aerospace alloys

Leading aerospace manufacturer Alcoa (NYSE:AA) has signed a long-term
contract to supply aluminum sheet and plate products to Boeing, the
world’s largest aerospace company and leading manufacturer of commercial
jetliners and defense, space and security systems. The multiyear
contract, valued at more than $1 billion, is the largest ever between
the two companies.

“This historic agreement not only continues the 35-year Alcoa-Boeing
partnership, it will take our collaboration on next-generation metallic
technologies even further,” said Klaus Kleinfeld, Alcoa Chairman and
Chief Executive Officer. “We are proud that Alcoa’s lightweight
structural solutions will continue to fly on Boeing’s most advanced
aircraft today, and that our metallic science leadership will contribute
to the Boeing aircraft of tomorrow.”

Notably, the agreement makes Alcoa sole supplier to Boeing for wing
skins on all of its metallic structure airplanes. Alcoa plate products,
used in applications such as wing ribs, wing skins or other structural
parts of the aircraft, will also be on every Boeing platform, including
the 787 Dreamliner.

Finally, the agreement establishes a foundation for continued
collaboration on new, high-strength and corrosion-resistant alloys,
including aluminum-lithium that could be used for complex structural
applications.

Alcoa’s aerospace business, which had revenues totaling $4 billion in
2013, holds leading market positions in aerospace sheet and plate
produced by its midstream business, Global Rolled Products (GRP) and in
aerospace forgings, extrusions, jet engine airfoils and fastening
systems produced by its downstream business, Engineered Products and
Solutions (EPS).

Additionally, Alcoa announced in the second quarter that it had signed a
definitive agreement to acquire Firth Rixson, a global leader in
aerospace jet engine components. The acquisition will further strengthen
Alcoa’s robust aerospace portfolio, positioning the Company to capture
additional aerospace growth with a broader range of multi-material,
value-add jet engine components.
