Gross margin for the first quarter of 2010 was $9.8 million, or 25.3% of revenue, compared to $7.8 million, or 19.5% of revenue, for the same quarter a year ago, primarily reflecting improved manufacturing efficiencies in the company’s Battery & Energy Products segment and improved  mix of high-margin communications systems revenue partially offset by a negative gross margin in the Energy Services segment. Operating expenses for the first quarter of 2010 totaled $8.9 million inclusive of $0.7 million of expenses for AMTI, which was acquired on March 20, 2009, compared to $10.0 million a year ago. Net income for the first quarter of 2010 was $0.3 million, or $0.02 per share, compared to a net loss of $2.5 million, or $0.15 per share, for the same quarter in 2009.
