Book-to-bill ratio reflects seasonal softening North America-based manufacturers of semiconductor equipment posted $975.3 million in orders worldwide in September 2013 (three-month average basis) and a book-to-bill ratio of 0.97, according to the September EMDS Book-to-Bill Report published today by SEMI. A book-to-bill of 0.97 means that $97 worth of orders were received for every $100 of product billed for the month. The three-month average of worldwide bookings in September 2013 was $975.3 million. The bookings figure is 8.3 percent lower than the final August 2013 level of $1.06 billion, and is 6.8 percent higher than the September 2012 order level of $912.8 million. The three-month average of worldwide billings in September 2013 was $1.01 billion. The billings figure is 7.1 percent lower than the final August 2013 level of $1.08 billion, and is 13.6 percent lower than the September 2012 billings level of $1.16 billion. “The book-to-bill ratio reflects seasonal softening and near-term deferral in capital spending in some segments of the industry,” said Denny McGuirk, president and CEO of SEMI. ”We expect that market demand for semiconductors will drive continued capacity investment in 2014.” The SEMI book-to-bill is a ratio of three-month moving averages of worldwide bookings and billings for North American-based semiconductor equipment manufacturers. Billings and bookings figures are in millions of U.S. dollars.
