Summary
Battery constrained model. 2022 auto sales of about 2.8 million and 2 trillion market valuation. Not including energy business.
Here is my comment
A few points:
1. there is now only a single Model 2/X line (previously parts were unified, parts specific to S or X), but now they are moving to two shifts.
2. Fremont (Model Y) and Shanghai (on existing site) are still ramping, capacity is likely to be over 1.5 M by the end of the year 2021. Any new building in Shanghai will be ramping up during 2022 and will have maybe 0.5 M production, although its capacity by year end will be much higher.
3. We really don't know the final capacity for the existing buildings at Austin and Berlin, capacities of 2 M and 0.5 M seem possible by end 2022, but will be much less at the start of 2022. So average capacity for 2022 is maybe 1.5 M. Any extra buildings will have limited production in 2022.
4. When estimating production a factor for down-time (maintenance, parts shortages, etc) needs to be applied to capacity. I use 0.85, other people I respect use 0.8, so with average capacity for 2022 of about 3.5 M, production will be 2.8 - 3.0 M at most. So probably battery constrained, unless cell production is higher than 100 GWh, this is entirely possible as there are suspicions that Elon was sandbagging the numbers on battery day.
5. You can simplify your model even further, just use an average revenue and profit per kWh of battery produced. If Tesla are production constrained (I think they will be in 2022), then they will allocate batteries in a manner that maximizes revenue (we can see this already in the delay in the Semi, as Model 3/Y give more revenue per kWh so have had priority).
