That's called Capital Expenditure. Page 9: https://ir.tesla.com/static-files/b2218d34-fbee-4f1f-ac95-05...
Q1 2019 had a CapEx of $279 Million. In contrast, Q1 2018 was a CapEx of $655 Million (Q1 2018 was during the Gigafactory "ramp up", so they needed to pay for all of the equipment as the factory became operational)
> I've always thought that FUD regarding Tesla is mostly caused by short-sightedness and that they're not profitable because every dollar they make is going towards expansion.
They posted an operating loss of $500 Million in Q1 2019.
* Revenues -- The price of the car. If someone pays $40,000 for a car, that is +$40,000 in Revenue.
* Cost of Revenue -- The price Tesla paid to make a car. Based on Q1 numbers, Tesla paid $32,561 to make a $40,000 sale.
* Operating Expenses -- The cost of service centers, sales staff, administration, research and development, etc. etc. These don't "scale" with the car like "cost of revenue" does. Tesla spent $1 Billion on OpEx in Q1 2019.
* Operating Profit/Loss: Revenues - Cost of Revenues - OpEx. Tesla lost $500 Million at this point.
* Net Loss: Don't forget the interest rate on loans: 157 Million for the quarter. Net Loss: $667 Million.
All in all a $667 Million loss.
---------
* CapEx -- The cost of expanding the business. Building factories, buying new equipment, etc. etc. $279 Million. "Equipment" still has value when you buy it, so this doesn't count as a cost. Theoretically, if the company were to go bankrupt, it would sell the equipment to other companies and make some amount back. So CapEx counts as an 'investment', not as a cost.
* Loans and stuff -- Various loans were paid off this past quarter. $653 Million total.
* Total cash flow out: -$1.593 Billion. (Tesla's cash dropped from $4.2 Billion to $2.6 Billion this past quarter)
All in all, you can figure it all out on page 7, 8, 9, and 10 of the paper: https://ir.tesla.com/static-files/b2218d34-fbee-4f1f-ac95-05...
