KALU Kaiser Aluminum Corporation

Kaiser Aluminum (NASDAQ: KALU) today announced the signing of a new long-term contract with Boeing to supply sheet and light gauge aluminum plate for use in Boeing commercial aircraft products. The new supply contract, which extends an existing agreement, effectively adds to a prior multi-year agreement for heavy-gauge plate between Boeing and Kaiser Aluminum signed earlier this year. "Kaiser Aluminum and Boeing have a long history of partnership, and this agreement further solidifies the long-term relationship between the two companies," said Jack A. Hockema, chairman, president and chief executive officer, Kaiser Aluminum. "We're pleased to extend our contract with Kaiser Aluminum," said John Byrne, Global Partners director of Purchased Outside Production and Common Commodities for Boeing Commercial Airplanes. "With the continued strong demand for new airplanes, Kaiser's support is invaluable to delivering the highest quality airplanes to our customers." The contract with Boeing is enabled by a previously-announced $105 million expansion at Kaiser Aluminum's Trentwood Rolling Mill in Spokane, Washington. Boeing is the world's leading aerospace company and the largest manufacturer of commercial jetliners and military aircraft combined. With additional capabilities in rotorcraft, electronic and defense systems, missiles, satellites, launch vehicles and advanced information and communication systems, the company's reach extends to customers in 145 countries. In terms of sales, Boeing is the largest U.S. exporter. Kaiser Aluminum is a leading producer of fabricated aluminum products for aerospace and high-strength, general engineering, and automotive and custom industrial applications. The company has more than 2,000 employees and 11 plants in North America and produces more than 500 million pounds annually of value-added sheet, plate, extrusions, forgings, rod, bar and tube.
