Blue Star reported a 25.2% year-over-year increase in net sales for the first quarter of fiscal year 2011, though margins declined and profit fell. While sales grew across all segments, higher input costs and lower commission income caused operating margins to drop 281 basis points year-over-year to 9.2%. Net profit declined 10% year-over-year due to the margin pressure and a change in accounting policy. However, the company's order backlog grew nearly 15% and the outlook for large orders remains positive.
