EDIT:
I made a mistake here. Free cash flow is operating income - capex.
I ran Tesla through a spreadsheet I made and some of the numbers are interesting. For starters, just look at Q2 of this year. Ratio of current assets to current liabilities is a bit more than 2, so the company is solvent for at least a year. Now look a bit closer at the numbers. Of the 1.13B in current assets, 746M or 66% is cash and short term investments. Since Tesla has not once had a positive operating income, where does this money come from? Flip to the cash flow page. For 2013:
Cash from selling stock: 590M
Cash from debt: 204M
Total = 794M
The company is literally borrowing money to make the minimum payments on its debt. It would be like I make $50,000 per year at my job, but food and shelter and medical adds up to $60,000. Since I'm running at a net loss, I borrow $100,000 from the bank and use that money to make the minimum payments on $100,000 debt. The bank statement says I'm sitting on a lot of cash, and I easily have enough to make the payments for a few years, but eventually I'll run out of money and go bankrupt.
It gets even more interesting when you realize the net income reported by a company is not really the net income. The reported net income does not include capital expenditures which would be things like putting new tires on a truck, fixing the roof, or other maintenance related things. The true net profit of a company is Free Cash Flow; it's the net income minus the capital expenditures. For Q1 of this year, the quarter everyone thinks was profitable, free cash flow was -46M. Q2 was -117M. This company is bleeding money like crazy. Tesla goes in the same category as AMD. It's here now, but it will eventually die. Actually, Tesla is doing WORSE than AMD because AMD had positive free cash flow for 2010 and 2011 while Tesla has never had positive free cash flow. AMD's current ratio is 1.69 even though they haven't taken on new debt and haven't sold many shares this year.
