Operating expenses for the third quarter of 2010 totaled $10.2 million compared to $10.8 million a year ago.

Kavazanjian, Ultralife’s president and chief executive officer. “Our focus on developing and selling higher-margin products with greater engineering content helped produce the third consecutive quarter of significant gross margin expansion. After taking into account the planned increase in product development, gross margin gains flowed through to operating income as we held firm on cost controls and realized operational efficiencies.
