Drunen, the Netherlands, July 5, 2005, BE Semiconductor Industries N.V. ("the
Company" or "Besi") (Nasdaq: BESI; Euronext: BESI), a leading manufacturer of
assembly equipment for the semiconductor industry, today announced preliminary
sales for the second quarter ended June 30, 2005.

Net sales for the second quarter ended June 30, 2005 are expected to be
approximately E 37 million, an increase of 1% as compared to E 36.6 million for
the first quarter of 2005, and a decrease of approximately 23% as compared to
pro forma net sales of E 48.3 million in the second quarter of 2004 (the pro
forma information reflects the acquisition of Datacon as if such transaction had
occurred on January 1, 2004). Orders for the quarter ended June 30, 2005 totaled
approximately E 38 million, a decrease of approximately 5% as compared to E 40.3
million for the first quarter of 2005 and a decrease of approximately 43% as
compared to pro forma orders of E 66.8 million in the second quarter of 2004. In
addition, backlog was up slightly to approximately E 55.5 million at June 30,
2005 as compared to E 54.5 million at March 31, 2005 and increased approximately
9% as compared to a pro forma backlog of E 50.9 million at December 31, 2004.

Richard W. Blickman, President and Chief Executive Officer of the Company,
commented: "We are disappointed with preliminary indications of our second
quarter net sales and orders. The net sales shortfall versus our expectations
was due primarily to unanticipated delays in shipments of two orders aggregating
to approximately E 6 million by two major customers for certain assembly and
test handling production equipment. We currently expect to ship these orders in
the third and fourth quarters of 2005. In addition, we see in our second quarter
order book that customers continue to remain cautious in placing purchase orders
for assembly equipment, a trend that has resulted in fluctuating levels of
bookings in recent quarters. Based on input from certain customers and industry
sources, we could see a positive development of assembly equipment orders in the
second half of our fiscal year, but anticipate that quarterly bookings will
continue to fluctuate."

BE Semiconductor Industries N.V. designs, develops, manufacturers, markets and
services die sorting, flip chip bonding and multi-chip die bonding, packaging
and plating equipment for the semiconductor industry's assembly operations. Its
customers consist primarily of leading U.S., European, Asian, Korean and
Japanese semiconductor manufacturers and subcontractors which utilize its
products for both array connect and conventional leadframe manufacturing
processes.
