I think shorts understand Tesla's CapEx very well. It's a key part of the bear argument.
Their Q4 letter said they expected higher CapEx in 2018 than 2017. Tesla's CFO said "way more than 50%" of that would go to the Model 3 ramp.
So, reading into that: Tesla has 3.5B cash and they're expecting to spend more than 3.4B on CapEx. Roughly 2B of the 3.5B cash on hand going just to CapEx for the Model 3.
This is the central argument! Cash is king, and if Tesla can't start producing the Model 3 profitably and at scale soon, they're screwed. It's right there in the 10K.
It's probably why Tesla is switching to 24/7 production. They've looked into the future, they see they can't afford the CapEx, and so their solution is to increase capital utilization. It's desperate and stroke evidence of a cash crunch. It's why I'm confidently short heading into earnings.
Plans can obviously change, and Tesla may be able to recover from a Model 3 blunder.
The issue is that, when you take out that Model 3 CapEx and customer deposits, you're left with maybe 1B cash, much of which was planned for other business functions.
How are they going to scale the Semi AND invest in autonomous driving AND begin Model Y production AND create a Roadster line AND pay off their debts?
... The shorts point to this as the trigger for a supplier run. When they pay is different from a commitment to pay. These machines are ordered months in advance. They can't just tell suppliers "hey, that machine we ordered, we don't want it anymore."
