North American Semiconductor Equipment Industry Posts August 2016 Book-to-Bill Ratio of 1.03

SAN JOSE, Calif. — September 15, 2016 — North America-based manufacturers of semiconductor equipment posted $1.75 billion in orders worldwide in August 2016 (three-month average basis) and a book-to-bill ratio of 1.03, according to the August  Equipment Market Data Subscription (EMDS) Book-to-Bill Report published today by SEMI.  A book-to-bill of 1.03 means that $103 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 August 2016 was $1.75 billion. The bookings figure is 2.3 percent lower than the final July 2016 level of $1.80 billion, and is 5.0 percent higher than the August 2015 order level of $1.67 billion.

The three-month average of worldwide billings in August 2016 was $1.71 billion. The billings figure is approximately the same as the final July 2016 level of $1.71 billion, and is 8.4 percent higher than the August 2015 billings level of $1.58 billion.

"The book-to-bill ratio has been at or above parity since December of last year with current monthly bookings and billings levels at $1.7 billion,” said Denny McGuirk, president and CEO of SEMI.  “Given the current data trends, North American equipment suppliers are clearly benefiting from strong investments by device manufacturers in the second half of the year.”

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.

The data are contained in a monthly Book-to-Bill Report published by SEMI. The report tracks billings and bookings worldwide of North American-headquartered manufacturers of equipment used to manufacture semiconductor devices, not billings and bookings of the chips themselves. The Book-to-Bill report is one of three reports included with the SEMI  Equipment Market Data Subscription (EMDS).
