The transfer between markets maintains ON Semiconductor's Nasdaq association and continued trading of the company's common stock under the symbol ONNN. The company expects to receive Nasdaq's approval decision within 14 days and will maintain its current National Market status pending the decision. ON Semiconductor believes that it meets all the criteria to have its common stock listed on the Nasdaq SmallCap Market and anticipates Nasdaq's approval of the transfer. Listing on the Nasdaq SmallCap Market enables ON Semiconductor to continue trading its common shares in a competitive, highly visible and well-regulated market that benefits all of its shareholders. In a similar fashion to the Nasdaq National Market, Nasdaq distributes immediate trading information on the Nasdaq SmallCap Market through financial Web sites, financial newspapers and general circulation newspapers so that investors can make timely and informed investment decisions. ON Semiconductor plans to execute on its strategy, continue to grow its gross margins, improve the strength of its financials and continue to build a great company. As the company proceeds with this transfer, it will provide updates on its Investor Relations Web site at http://www.onsemi.com.
