(Reuters) - Aerovironment Inc (AVAV.O) posted a better-than-expected quarterly profit as its unmanned aircraft unit sold more fixed-price products, sending its shares up 9 percent after the bell.
Higher sales of its industrial electric vehicle charging product, Posicharge, and overhead cost reduction also contributed to the margins, Chief Executive Tim Conver said on a conference call.
Aerovironment draws about 80 percent of its revenue from the unmanned aircraft systems segment, which is known for drones like the Raven, Wasp and Puma.
Earnings rose to $8.7 million, or 39 cents per share, for the second quarter, from $6.6 million, or 30 cents per share, a year earlier.
Revenue fell marginally to $80.28 million. Gross margins rose to $35.6 million from $30.6 million.
