Exhibit 99.1 BTU International Reports Second Quarter 2003 Results NORTH BILLERICA, Mass.--(BUSINESS WIRE)--July 22, 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 second quarter ended June 29, 2003. Net sales for the quarter were $7.1 million, up 4 percent compared to $6.8 million in the preceding quarter, and down 24 percent compared to $9.4 million recorded in the second quarter of 2002. Net loss for the 2003 second quarter was $1.9 million, or $0.27 per share, compared to a net loss of $1.8 million, or $0.25 per share, in the preceding quarter. The net loss reported in the second quarter of 2002 was $1.5 million, or $0.21 per share. Net sales for the six months ending June 29, 2003 were $14.0 million, compared to $17.9 million in the same period of last year. The loss before restructuring was $3.6 million for the first half of 2003 compared to $3.6 million for the same period last year. The net loss for the first six months was $3.6 million, or $0.52 per share, compared to a loss of $2.8 million, or $0.40 per share for the first six months of last year. The difference in tax benefit between the respective periods of $0.7 million or $0.10 per share was due to the availability of greater tax benefit in the first half of last year. Mark R. Rosenzweig, president and CEO of BTU International said, "Our quarterly revenues increased sequentially, primarily as a result of increased sales in the surface-mount-technology (SMT) segment of our business. However, quarterly margins were negatively impacted by a change in product mix, and with a restructuring charge for workforce reduction, the bottom line was slightly down from last quarter." "In general, we see improving market forecasts, with significantly increased interest on the part of our major customers, but this increased interest is slow in turning into increased orders," said Rosenzweig. "SMT business appears to be recovering, and both semiconductor wafer bumping and wafer packaging are showing signs of strength, especially in Asia where we are well positioned to take advantage of any upturn. Construction of our new manufacturing facility in China continues on schedule." "We continue to fully fund our R&D projects with the goal to complete our major projects in time to take full advantage of the recovery in our markets. With the added scope from our Sagarus acquisition in robotics and flux coating and our own internal development, we will be offering an expanded line of products for all our major market segments," said Rosenzweig. "At the same time, we continue to exercise strict controls on expenditures and structure to maintain the company's financial strength and flexibility to meet customer demands." BTU will be discussing its financial results, along with its outlook for the third quarter of 2003, in a conference call tomorrow, Wednesday, July 23, at 11:00 a.m. Eastern Time.
