But without their spending, they wouldn't have become Amazon. Without Tesla's spending, they won't be a future company, they'll just be a tiny car company.
It's amazing just how many people on different sites (stocktwits, seeking alpha, reddit) continue the "they're losing money, why are they valued so highly?" comments. How is it not obvious what Tesla is trying to do? The operative thing isn't that they're losing money, its that they're spending everything they've got. This is a good thing. The Starcraft analogy is simple to make: The winning player is the one that spends all their resources, not the one that hoards them. Nobody raises cash just to hold on to it. I have no idea why people can't grasp this.
For earnings, what matters is whether or not revenue is higher than expected ($2.79B vs. $2.51B estimated) and what the gross margins are (27.9%). Check and check.

Bit of a diversion:
For some historical comparison: Amazon added $6bn in debt as recently as 2014. Even very large and very successful companies take on debt to fuel growth far beyond "bootstrap" numbers. Both companies leverage as much investment money as they can to build and expand as fast as they can. If you look at Amazon's raises in the late 1990's you'll find something more comparable to Tesla today relative to revenue. In 1999 Amazon raised $1.25 billion, and their revenue for the year was $1.64 billion. So they raised proportionally way more money than Tesla has so far this year. And spent it all!
(Also note the crazy growth: 293 million in Q1 to to 676 million in Q4 for Amazon that year. They were expanding like mad, but they still needed way more money than they were producing to reach their goals. http://www.wikinvest.com/stock/Amazon.com_(AMZN)/Data/Revenu...)
