North American Semiconductor Equipment Industry Posts June 2013 Book-to-Bill Ratio of 1.10

SAN JOSE, Calif. — July 18, 2013 — North America-based manufacturers of semiconductor equipment posted $1.33 billion in orders worldwide in June 2013 (three-month average basis) and a book-to-bill ratio of 1.10, according to the June EMDS Book-to-Bill Report published today by SEMI.   A book-to-bill of 1.10 means that $110 worth of orders were received for every $100 of product billed for the month.

The three-month average of worldwide bookings in June 2013 was $1.33 billion. The bookings figure is 0.7 percent higher than the final May 2013 level of $1.32 billion, and is 6.6 percent lower than the June 2012 order level of $1.42 billion.

The three-month average of worldwide billings in June 2013 was $1.21 billion. The billings figure is 1.4 percent lower than the final May 2013 level of $1.22 billion, and is 21.4 percent lower than the June 2012 billings level of $1.54 billion.

“The SEMI book-to-bill ratio has been above parity for six consecutive months and bookings in the quarter ending in June are 20 percent above the quarter ending in March,” said Denny McGuirk, president and CEO of SEMI.  "As recently announced, we anticipate that total worldwide equipment spending will decline by low single-digits this year and rebound with a double-digit growth rate 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.
