BTU International Reports Third Quarter 2003 Results

    NORTH BILLERICA, Mass.--(BUSINESS WIRE)--Oct. 16, 2003--BTU
International, Inc. (Nasdaq NM: BTUI), the leading supplier of
advanced thermal processing equipment for semiconductor packaging,
surface mount, and advanced materials processing, today announced its
financial results for the third quarter ended September 28, 2003.
    Net sales for the quarter were $6.7 million, compared to $7.1 in
the third quarter of 2002. Net loss for the 2003 third quarter was
$1.6 million, or $0.23 per share, compared to a net loss of $1.7
million, or $0.24 per share in the third quarter of 2002.
    Net sales for the nine months ending September 28, 2003 were $20.7
million, compared to $25.0 million in the same period of last year.
The net loss for the first nine months was $5.3 million, or $0.75 per
share, compared to a loss of $4.4 million, or $0.64 per share, for the
first nine months of last year.
    "Net sales in the third quarter were, as expected, down slightly
compared to the second quarter, primarily due to weak sales early in
the summer," said Mark R. Rosenzweig, president and CEO of BTU
International. "The surface-mount-technology (SMT) area of our
business continued its recovery, but orders from the advanced
materials markets have not yet rebounded, and the resulting product
mix continues to put downward pressure on gross margins."
    "Early recognition of the sales weakness in quarter three enabled
us to reduce operating costs significantly, primarily through a
temporary shortening of our workweek," said Rosenzweig. "Even with
lower sales, the company ended the quarter essentially cash neutral
and with an improved bottom line."
    Commenting on the fact that the company's SMT and semiconductor
oriented businesses continue to be increasingly focused in Asia,
Rosenzweig said, "We are well positioned to take advantage of that
market strength, especially as our new manufacturing facility nears
completion in China. We expect to begin production in Shanghai in
early 2004 and plan to ramp output quickly with a corresponding
increase in quarter-on-quarter gross margins next year."
    "Based on the improved activity in the later part of the third
quarter, we are back to full operations and expect improving sales in
the quarter ahead," added Rosenzweig.
    BTU will be discussing its financial results, along with its
outlook for the fourth quarter of 2003, in a conference call to be
held tomorrow, Friday, October 17, at 11:00 a.m. Eastern Time. A
webcast of the conference call will be available on BTU's website at
www.btu.com or at www.streetevents.com. Replays of the call will be
available through October 31, 2003, and can be accessed at these
websites or by phone at (800) 938-0996.
