Com Dev’s net earnings climbed to $5.2 million on $50.1 million in revenue generated in the three-month period ending April 30, compared with a profit of $1.3 million on $53.1 million in sales recorded in the previous year.

   The company’s space equipment division posted sales of $47.5 million, down from $51 million a year earlier. The unit’s margins, however, rose to 24 percent from 22 percent in the 2011 second-quarter. Com Dev data services revenue rose from $2 million in 2011 to $2.5 million in 2012, while gross margins jumped from 8 percent to 12 percent during the same period of time.

   Com Dev’s gross margins widened to 25 percent from 21 percent, thanks to stronger results in the core equipment business and progress in the data services unit, the company said in the report.
