For the record, I'm calculating the numbers for 2020, not any year before. I will do an estimate for CapEx before end of 2018 at the end.
I agree they probably won't need another GF until 2020 (not so sure though, have my reservations), but they definitely can't wait until 2020 to start building another one. Therefore there will be the CapEx for GF2 before 2020. Let's also assume partnership will be wider and deeper for the next GF and Tesla won't need to commit as much as GF1. Under these ideal situations, 1 billion of CapEx is still quite a conservative number.
The scale of the current line can only support about 50k per year. Assume they increase efficiency and also due to the simpler design of Model 3 let's say in the future one line can give you 75k per year. The cost of the Model S line is about 1.3 billion (80% of their CapEx in 2011-2014, when little was spend on GF and X). We don't know how much is spent on the X line but 2015 CapEx is in the ballpark of 2 billion and majority of this is for X line and GF so I don't think the X line will be any cheaper than 1 b since GF is only phase 1 and there's still a lot to be spent on it. So roughly we get 1.3b for 75k/year production for Model 3. If we want to crunch out 350-400k of 3s in 2020, there will be about 5 more lines needed, or 6 billion of CapEx.
Then there's unknown amount of CapEx needed for factories in China and Europe. Let's be generous and say Tesla only needs 1 billion for both of them.
Then you have 8 billion of CapEx before end of 2020 under very very optimistic assumptions. Consider 75% of these will happen in 2019 and 2020 thanks to the majority of Model 3 ramp up will happen in those two years. Tesla then needs 2 billion for 2016, 2017, and 2018.
On the income side, operating profit won't be that high. At current levels, OpEx is about 20% of their total revenue and scaling very well with their delivery numbers, especially SG&A cost (jumped a bit from in Q3 2015, hope it's a one time event). In an optimistic case of GM 30% before GF, selling 100k per year with ASP 105k, you get 3.15 billion gross profit a year. Their total OpEx in 2015 has already accumulated to 1.16b so far and if we use the average ratio of OpEx/deliveries, we'll get 1.76b for 50k cars. So for 100k cars, that's 3.5b OpEx for you. In this case Tesla won't even be operating profitable. So let's assume under OpEx, only SG&A scales with deliveries, RND is kept constant at about 180m/quarter, which is 720m a year. SG&A scales with deliveries and would be 1.92b for 100k cars. That gives you 2.64b in OpEx, leaving 500m of operating profit on the table each year. Regarding to Tesla Energy, without the full force of GF to reduce its cost, I don't think the operating profit of it will be high. 3-5% would make me super happy. And even if they sell 3.75b revenue of batteries, which is the full capacity of the GF reserved for TE, under operating profit 3%, 5%, 10%, you get 0.1-0.375 b of operating profit from it. Before 2018, the operating profit from TE would be about 200m a year at best. So let's say total operating profit from TE in 2016-2018 gives a boost of 500m. The total operating profit for these three years sums up to 2 billion at best.
Therefore, under the most optimistic case of CapEx requirement, and most optimistic case of Operating profit achieved, Tesla may not need to raise capital before 2019. But have things ever turn out to be the most optimistic case for Tesla?
PS, I'm not a bear. DCA all the way whenever TSLA starts falling. Just wish to be more realistic based on the numbers we have.
It does not add up to $10B before Model 3 is ramped up, which should happen second half of 2018. They need another line or two in Fremont and they need to complete a part of GF, not the whole factory. And maybe start another vehicle factory project in Europe or Asia. They do not need another GF before 2020, as they can expand the current one. There is also the Tesla Energy industry packs that will fund a part of the GF expansion.
Also, Model S+X will generate far more than $0.5B a year if they produce 100k+ per year. My estimates are that in total for 2017 and 2018 they will get almost $5B from S+X, and in 2016 maybe $1.5B.
So we are looking at $6.5B up to and including 2018. If this sounds high then consider that they have a highly automated vertically integrated factory that sells $90k+ vehicles. Material goes in and the vehicle comes out.
Now those $6.5B should cover a lot so there will be capital raise required, but not close to $10B or I think around $8B in your scenario? This is one of the errors I think the bears make (not saying you are a bear). The most common error is that they discount with a ridiculous rate and then add like 100% share dilution.
