UQM (NYSE MKT: UQM), which is headquartered outside of Longmont, suffered losses of $4.9 million, or 14 per share, for its fiscal year, which also ended March 31.
The quarterly loss compares to a $195,000, or 1 cent per share, net loss for the same period last year.
The loss comes despite a 61-percent increase in revenues to $3.8 million during the quarter. Total revenues for the year hit $10.1 million, up from $9 million the year before.
The revenue gains were primarily attributed to sales to CODA, a California-based electric car manufacturer, UQM said in a release.
