STURBRIDGE, Mass., April 26 -- Galileo Corporation reported net income of $180,000, or $.02 per share, on sales of $10.8 million for its second quarter of fiscal 1999. For the second quarter of the previous fiscal year, the company had reported a net loss of $896,000, or a loss of $.12 per share, on sales of $11.5 million. Lower sales in the company's Scientific Detector Products business led to a 5.5% drop in sales for the quarter as compared with the same period last year.Galileo attributed its improved profitability to the recent realignment of the company's businesses, discontinuation of certain development programs, write-offs of some non-productive assets, and aggressive cost reductions. President and CEO W. Kip Speyer said that the second quarter results demonstrate that Galileo has started to meet its objective of restoring profitability and credibility through tangible accomplishments.
