BTU International Reports Fourth Quarter and Fiscal Year 2007 Results

2007 Solar energy equipment sales doubled; bookings up 2.5X.

NORTH BILLERICA, Mass.--(BUSINESS WIRE)--BTU International, Inc. (Nasdaq: BTUI), a leading supplier of advanced thermal processing equipment for the alternative energy and electronics manufacturing markets, today announced its financial results for the fourth quarter and fiscal year ended December 31, 2007.

Fourth quarter net sales were $18.3 million, up 11 percent compared to $16.5 million in the preceding quarter, and up 10 percent compared to $16.6 million for the same quarter a year ago. Net income for the fourth quarter of 2007 was $0.6 million, or $0.06 per diluted share, compared to a net income of $0.5 million, or $0.06 per diluted share, in the preceding quarter, and compared to a net income of $1.0 million, or $0.11 per diluted share, in the fourth quarter of 2006.

Net sales for the year 2007 were $ 63.7 million compared to $78.3 million for the year 2006. Net income for 2007 was $ 1.9 million, or $0.21 per diluted share, compared to a net income of $9.2 million, or $0.98 per diluted share, for 2006.

Comments

Commenting on the company’s performance, Paul J. van der Wansem, chairman and CEO, said: “Revenues and income before tax for the quarter were in line with expectations. However, the per share earnings were negatively impacted by $0.04 due to a higher than forecasted effective tax rate in one of our overseas subsidiaries.”

“For 2007 the electronics assembly business was down by 30 percent compared to the previous year. On the other hand, we saw strong growth in our alternative energy business. In solar photovoltaics, we were able to double our revenues for the year and bookings increased by more than two and a half times. We achieved our goals and are on track with our performance and growth potential in both silicon and thin film based technologies.”

Outlook

“As we enter 2008, BTU is rapidly implementing a strategy based upon the success in our energy related businesses. We have set up a new Energy Business Group, and hired key individuals to drive the strategy and prepare for the expected growth. We believe that we can optimize our performance and maximize the return for our investors by aggressively pursuing these opportunities. In addition, we are investing heavily in technology and new product development.”

“The cost of these initiatives, coupled with the recent turmoil in the financial markets and potentially lower capital expenditures for at least the next few quarters—which affects primarily our electronics assembly business—will no doubt have a near-term negative impact on our bottom line. The investments we are making are critically necessary to fully exploit the opportunities before us in alternative energy-related businesses. We are purposely choosing the course that will maximize our longer term success.”

“As regards the first quarter of 2008, we expect revenues to be in a range of $15.8 to $ 16.8 million. We also expect the bottom line for the first quarter to be marginally profitable due to the higher level of expenses for the buildup of the energy business.”

“We aim to double our solar business in 2008 as compared to 2007, and are pursuing a strategy that will allow us to double again for 2009. Our actions and plans for our energy business are described more fully in a separate press release issued today,” concluded van der Wansem.
