North American Semiconductor Equipment Industry Posts October 2015 Book-to-Bill Ratio of 0.98

SAN JOSE, Calif. — November 19, 2015 — North America-based manufacturers of semiconductor equipment posted $1.33 billion in orders worldwide in October 2015 (three-month average basis) and a book-to-bill ratio of 0.98, according to the October EMDS Book-to-Bill Report published today by SEMI.  A book-to-bill of 0.98 means that $98 worth of orders were received for every $100 of product billed for the month.

SEMI reports that the three-month average of worldwide bookings in October 2015 was $1.33 billion. The bookings figure is 14.7 percent lower than the final September 2015 level of $1.55 billion, and is 20.3 percent higher than the October 2014 order level of $1.10 billion.

The three-month average of worldwide billings in October 2015 was $1.36 billion. The billings figure is 9.1 percent lower than the final September 2015 level of $1.50 billion, and is 14.7 percent higher than the October 2014 billings level of $1.18 billion.

"Both bookings and billings weakened for the second consecutive month; however, year-to-date bookings and billings levels remain above last year's levels," said Denny McGuirk, president and CEO of  SEMI. "SEMI will update its 2016 equipment outlook during SEMICON Japan next month."

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.
