Still, as Tesla rolls out its highly-anticipated Model S, CEO Elon Musk indicated strong sales figures could push the company to a profit in coming quarters.

Demand is strong for the Model S, Musk said on the conference call.

For the full year, Tesla expects to deliver about 20,000 Model S units, with 4,500 of them in the first quarter. Tesla expects first-quarter gross margins to be in the midteens and rise toward its target of 25% in the second half of the year. "We really have very high confidence that we will have a profitable first-quarter," Musk said.

Tesla shares ended the week down 8.0% at $36.11.
