While Tesla’s stock price has zoomed up over the last six months, the company’s value has crashed over 12 percent in after-hours trading on Tuesday—hovering around $155 per share. (Ars recently reviewed the Model S.)

The electric sportscar firm announced that it sustained a net loss of over $38 million in the third quarter of 2013. However, Tesla did beat Wall Street analysts' projections, who estimated 11 cents a share on $534.64 million in revenue. The company actually made 12 cents a share on $603 million in quarterly revenue.

By contrast, the automaker sustained a quarterly profit of over $11 million the Q1 2013 and quarterly loss of over $30 million in Q2 of 2013. In short, barring an astonishingly good end of 2013, the company will have lost money for the fourth straight year.

“We are now producing 550 cars per week with improved process controls which consistently result in high quality cars,” the company said in a statement. “Consequently, we finished the quarter with a record of slightly over 5,500 deliveries, including over 1,000 deliveries to European customers. Production in the quarter significantly exceeded deliveries in order to fill the pipeline of vehicles in transit to Europe and provide cars for service and marketing uses.”

In the same statement, CEO Elon Musk added that the company’s next quarter research and development expenses would “increase sequentially by about 25 percent in Q4 as we accelerate product development efforts on Model X and Model S enhancements.”
