I don't know the book, but a highly profitable business doesn't rack up over $2 billion in net losses and only have a single profitable quarter.
I've pointed this the massive losses numerous times. Now with this latest software, there are reactions like dislike and funny to my post at Prediction: Model 3 Orders to reach 100k in 24 hours. Hmmm... is it that some people just don't like to hear reality and like to explain things away?
Let's see if Tesla is able to turn consistent profits (high or not) once Model 3 production is up at a healthy clip. If not, I don't think apologists and fanboys will have any more excuses about investment for R&D, future products, capital investment, etc. ALL major automakers do this ALL the time (and have WAY more models and product lines) and aren't standing still, yet they can and do turn profits.
There are companies like Amazon who didn't turn a profit for nearly 20 years, but I don't think many people would claim they weren't successful.
I suspect Tesla will do much better in Q1 16. The Model X has turned from a multi-year money pit into a money maker and they scaled back things like Supercharger expansion. I don't know if they will actually report a profit, but any loss will be much smaller.
Tesla runs in the red because they are choosing to spend heavily on R&D and expansion. If they pulled in the reins and cut out the voluntary expenses, they would be quite profitable. Once the Model 3 is being produced in good numbers, they will have five products producing incomes (3 cars plus two stationary storage products). The base supporting their expansion and R&D will be broader and they should be able to break even. Like Amazon, I doubt they will be turning much of a profit for some time to come. Anything they make will be plowed back into the company. But the red ink should trickle down to nothing within a year of the Model 3 launch.
That is if things go right. There are two things that could kill Tesla at this point: an economic collapse or a major screw up scaling up to build the Model 3. Those are about the only likely scenarios that could kill them at this point.
