TESSCO Technologies, provider of product and supply chain solutions, reported record earnings for its first quarter, which ended June 29, 2008. Earnings per share reached a record $0.38.

“We made excellent progress on all fronts, in a difficult economy,” said Chairman, President and CEO Robert Barnhill, in a release. “Revenues in our ‘non-concentrated’ customer base grew 9% year over year. Our gross margin exceeded 25%, a 12% increase compared to the first quarter of last year, driven by improved gross margins in all three commercial markets. Our productivity initiatives led to operating margin improvement, as expenses remained in line while gross profit increased.”

In network infrastructure, the company posted $42.9 million, which was an increase of 7.5% thanks to higher sales of RF propagation and site support products. Revenues for its mobile devices and accessories totaled $58 million, decreasing 8.1% due to a decline in cellular accessory sales to resellers. Revenues for the company’s installation, test and maintenance division were $21.2 million, a 1.2% decrease.
