APOGEE PLANS AN INVESTMENT IN

ITS ARCHITECTURAL GLASS SUBSIDIARY, VIRACON

MINNEAPOLIS, MN (January 22, 2013) – Apogee Enterprises, Inc. today indicated that it plans to invest in the manufacturing process of its architectural glass subsidiary, Viracon. The 18-month project, which requires an investment of more than $30 million that will be spent during three fiscal years, will improve efficiencies and allow Viracon to offer the new products required to strengthen its competitive position.

Apogee is comparing the cost and benefits of making this investment in one of Viracon’s two largest locations, either in Owatonna, MN or Statesboro, GA. As part of this effort, Apogee is pursuing state and local support for both locations to ensure that the investment is made in the location that best strengthens Viracon’s competitive position.

Viracon glass creates the distinctive look of many buildings globally, including every major project at the World Trade Center reconstruction in New York City; Petronas Towers in Kuala Lumpur, Malaysia, among the tallest buildings in the world; and the Xcel Energy Center, the University of Minnesota TCF Stadium, the Minneapolis Central Library and Best Buy headquarters in Minnesota. Viracon currently employs approximately 2,000 people in the United States, with more than 1,000 located in Owatonna. Prior to the recession, it employed approximately 3,000.
