North American Semiconductor Equipment Industry Posts September 2014 Book-to-Bill Ratio of 0.94

SAN JOSE, Calif. — October 20, 2014 — North America-based manufacturers of semiconductor equipment posted $1.17 billion in orders worldwide in September 2014 (three-month average basis) and a book-to-bill ratio of 0.94, according to the September EMDS Book-to-Bill Report published today by SEMI.   A book-to-bill of 0.94 means that $94 worth of orders were received for every $100 of product billed for the month.

The three-month average of worldwide bookings in September 2014 was $1.17 billion. The bookings figure is 12.9 percent lower than the final August 2014 level of $1.35 billion, and is 18.1 percent higher than the September 2013 order level of $992.8 million.

The three-month average of worldwide billings in September 2014 was $1.25 billion. The billings figure is 3.3 percent lower than the final August 2014 level of $1.29 billion, and is 22.5 percent higher than the September 2013 billings level of $1.02 billion.

“Following 11 months of above parity book-to-bill ratios, the three-month average ratio declined in September,” said Denny McGuirk, president and CEO of SEMI.  "While order activity moderated, equipment spending this year is expected to be robust and remain on pace for double-digit year-over-year growth.”

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.
