Electric car company Tesla Motors turned a profit for the first time since 2013, Reuters reported on Thursday.

Once an ingénue, the company has struggled over the last few years, with faith in their technology fading after the death of a driver using Autopilot. The Model 3 Sedan, allegedly the car to bring Tesla into the mass market, is still on track to start shipping in late 2017 from the Gigafactory, which opened in July.  The company has lowered its projected capital spending forecast for 2017 by 20 percent, to $1.8 billion.

CEO Elon Musk said that the company does not need to raise any capital to complete the Model 3 roll-out, but that a profit would help “”account for uncertainty … and de-risk the business”.

A lot of that capital comes not from the sale of cars but from clean car credits. Tesla made almost $139 million from the sale of California zero emission vehicle credits, which can be sold to other carmakers even if those companies don’t make their own electric vehicles. Selling clean energy credits is “a near 100 percent profit business,” analyst Jeffrey Osborne told Reuters.

Tesla also recently took a risk in acquiring SolarCity, which is already saddled with its own debt.

The automaker’s net income was $21.9 million in the third quarter of 2016. Stock in both Tesla and SolarCity were up in after-hours trading on Thursday.
