Richard S. Hill, Chairman and Chief Executive Officer said, “This current upturn in semiconductor demand is being fueled by growth in a wide spectrum of electronics products. We anticipate that the “gentrification” of the worldwide communications infrastructure along with increased public-sector IT investment and growth in China consumerism will continue to support a multi-year recovery in the semiconductor equipment industry. In this robust environment, Novellus has continued to improve on all our operational metrics, while remaining on track with our financial business model.” Hill also added, “We are very excited about our new suite of products for the advanced wafer level packaging (WLP) market. This includes the introduction of SABRE 3D, a new wet processing platform with launch applications focused on 3D interconnects. This new and growing market opportunity allows Novellus to leverage our leadership in interconnect technology and productivity to meet the new and ever more challenging technical requirements and cost constraints of 3D integration. We believe that the “New Vertical Reality” of semiconductor technology promises ever increasing value for our customers.”

Management uses non-GAAP measures to evaluate operating performance. The discussion of bookings and shipments are not in accordance with GAAP and may differ from non-GAAP methods of accounting and reporting used by other companies. We discuss bookings and shipments because we believe these metrics assist investors to assess certain business trends in the same way that these trends are analyzed by management. Non-GAAP numbers are merely a supplement to, and not a replacement for, GAAP financial measures.
