         BTU International Reports Third Quarter 2006 Results

    NORTH BILLERICA, Mass.--(BUSINESS WIRE)--Oct. 24, 2006--BTU
International, Inc. (Nasdaq NM: BTUI), a leading supplier of advanced
thermal processing equipment for the electronics manufacturing and
alternative energy generation markets, today announced its financial
results for the third quarter ended October 1, 2006.

    Net sales for the quarter ended October 1, 2006, were $18.3
million, down two percent compared to $18.5 million for the third
quarter of 2005, and down 19 percent compared to sales of $22.5
million in the preceding quarter.

    Net income for the 2006 third quarter was up 48 percent at $2.3
million, or $0.25 per diluted share, compared to a net income of $1.6
million, or $0.20 per diluted share, reported in the third quarter of
2005, and down 27 percent compared to a net income of $3.2 million, or
$0.34 per diluted share, in the preceding quarter.

    Net sales for the first nine months of 2006 were $61.7 million, an
increase of 31 percent compared to the same period last year. Net
income for the nine months ended October 1, 2006, more than tripled to
$8.2 million, or $0.87 per diluted share, compared to a net income of
$2.5 million, or $0.34 per diluted share, for the first nine months of
2005.

    Commenting on the company's performance, Paul J. van der Wansem,
chairman and CEO, said, "Although our third quarter sales were below
our earlier expectations, our cost control programs and higher product
margins contributed to a solid quarterly profit. Our solar energy
business continued to be strong, while we experienced softness in the
electronics markets."

    Outlook

    "We are enthusiastic about the long-term market opportunities in
solar energy and electronics and are expanding the development of new
products for these sectors. Near term, sales for the fourth quarter
are expected to be equal to the third quarter plus-or-minus five
percent with earnings per share in the $0.22 to $0.27 range,"
concluded van der Wansem.
