"This past year marked one of the most protracted down cycles for the semiconductor industry and the company since ON Semiconductor's inception in 1999," said Keith Jackson, president and CEO of ON Semiconductor. "The weak demand environment throughout 2012 proved to be challenging - especially following a year in which both ON Semiconductor and our SANYO Semiconductor Products Group were negatively impacted by two catastrophic natural disasters and the strengthening of the Yen. In response, we took several strategic actions to reduce our cost structure. In 2013, we will continue to take additional actions at our SANYO Semiconductor Products Group to reduce the break-even level and return this operating segment to profitability.
"As we look forward into 2013, we continue to see improvement in our bookings trends. Our new product and technology offerings are gaining traction with our customers and we achieved significant design wins for the company in 2012, especially in automotive and handset applications. This improvement, along with increasingly lean inventory levels at our customers and distributors, leads us to believe that we are seeing the bottoming of the down cycle. We believe we are positioned well to take advantage of the next up cycle."
"Based upon product booking trends, backlog levels, and estimated turns levels, we anticipate that total ON Semiconductor revenues will be approximately $645 to $685 million in the first quarter of 2013," Jackson said. "Backlog levels for the first quarter of 2013 represent approximately 80 to 85 percent of our anticipated first quarter 2013 revenues. We expect that average selling prices for the first quarter of 2013 will be down approximately two percent when compared to the fourth quarter of 2012. The non-GAAP outlook for the first quarter of 2013 includes stock-based compensation expense of approximately $6 to $8 million."
