North America-based manufacturers of semiconductor equipment posted $1.56 billion in orders worldwide in May 2015 (three-month average basis) and a book-to-bill ratio of 0.99, according to the May EMDS Book-to-Bill Report published today by SEMI.   A book-to-bill of 0.99 means that $99 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 May 2015 was $1.56 billion. The bookings figure is 0.8 percent lower than the final April 2015 level of $1.57 billion, and is 11.0 percent higher than the May 2014 order level of $1.41 billion.

The three-month average of worldwide billings in May 2015 was $1.57 billion. The billings figure is 3.7 percent higher than the final April 2015 level of $1.51 billion, and is 11.6 percent higher than the May 2014 billings level of $1.41 billion.

“The May book-to-bill ratio slipped below parity as billings improved and bookings dipped slightly from April’s values,” said Denny McGuirk, president and CEO of SEMI.  “Compared to one year ago, both bookings and billings continue to trend at higher levels.”

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.
