So in terms of financials, here's the key points from Elon's memo:
Company Update
"In Q3 last year, we were able to make a 4% profit. While small by most standards, I would still consider this our first meaningful profit in the 15 years since we created Tesla."
"In Q4, preliminary, unaudited results indicate that
we again made a GAAP profit, but less than Q3."
This quarter, as with Q3, shipment of higher priced Model 3 variants (this time to Europe and Asia) will hopefully allow us,
with great difficulty, effort and some luck, to target a tiny profit.
So Q4 was profitable, but less than expected.
Elon is framing Q1 profits as a cliff-hanger in his usual "only the paranoid survive" style - but I think Q1 profits are going to be more than just tiny, with 100D/P100D sales and high trim units in Europe and China.
Another big question is free cash flow - and that might be quite healthy in Q4 due to the significant receivables boost they get compared to Q3.
