Ultralife Increases Second Quarter and Full Year Revenue Guidance

NEWARK, N.Y.--(BUSINESS WIRE)--Ultralife (NASDAQ: ULBI) announced that, based on a review of its progress for the second quarter ending June 28, the company expects to report revenue in excess of $75 million. These expected results compare to management’s previous guidance, which estimated revenue in the range of approximately $60 million to $70 million. For the full year 2008, the company now forecasts revenue of at least $250 million.

“The revenue increase is attributable to strong shipments to date, strong backlog in most businesses and requests from customers for accelerated deliveries against their orders,” said John D. Kavazanjian, Ultralife's president and chief executive officer. “We will provide more details about our second quarter performance and the outlook for the third quarter and full year when we report second quarter results, currently planned for July 31, 2008.”
