NEWARK, N.Y., May 2, 2013 (GLOBE NEWSWIRE) -- Ultralife Corporation (Nasdaq:ULBI) reported an operating profit from continuing operations of $0.4 million on revenue of $21.0 million for the quarter ended March 31, 2013. For the first quarter of 2012, the company reported an operating loss from continuing operations of $1.3 million on revenue of $27.5 million. "Through solid execution in the face of ongoing softness in our Battery & Energy Products business, we delivered our third consecutive profitable quarter, consistent with our internal expectations, and reversed last year's operating loss," said Michael D. Popielec, Ultralife's president and chief executive officer. "Despite the budget pressures confronted by our U.S. government/defense customers, our plans to diversify our revenue by driving international and commercial opportunities are proceeding, and we are still planning for modest revenue gains in our Battery & Energy Products business in 2013. Revenue for our Communications Systems business grew by 7% and we expect year-over-year growth to continue throughout 2013 based on our opportunity funnel and anticipated timing of pending projects. As a result, with an efficient and profitable business model and strong cash generation, we remain well positioned to realize operating leverage gains on revenue growth during 2013." First Quarter 2013 Financial Results Discontinued operations for the first quarter of 2013 include the final settlement of our obligation to return our former UK facility back to its original condition per a previous contractual commitment. For the first quarter of 2012 discontinued operations include the operating results of RedBlack which was sold in the third quarter of 2012. All revenue, gross margin and operating expense amounts presented below represent results from continuing operations. Revenue was $21.0 million, compared to $27.5 million for the first quarter of 2012, a 24% decline, reflecting an increase of $0.5 million in Communications Systems sales offset by a $7.0 million decrease in Battery & Energy Products sales. As a result of continued new business development, the mix of sales from international customers increased to 46% from 37% for the first quarter last year. Battery & Energy Products sales were $13.1 million, compared to $20.1 million last year, a 35% decline, reflecting for the most part the continued slowdown in U.S. government and defense order rate for rechargeable and non-rechargeable batteries and charger systems. Communications Systems sales were $8.0 million, compared to $7.4 million for the same period last year, an increase of 7%, reflecting the fulfillment of large orders for amplifiers from international defense customers and continued demand for amplifiers from the U.S. government.
