$14.1B - $7.1B - $4.6B = $2.4B
Driver bonuses fall under cost of revenue, and user promotions fall under sales and marketing. It’s only after subtracting other overhead that the company becomes unprofitable.
Other overhead includes operations and support, research and development, and general administrative. If you read the descriptions of these categories it becomes apparent that they are going to need to lay people off if they cut spending there. Sales and marketing also includes a lot of headcount.
All the above math includes both rides and eats. There are other numbers in the annual report that show that rides is making more money overall while other areas are losing more.
Realistically, they need to cut from pretty much everywhere, especially with revenue tanking during COVID. Even without that one-time IPO related payout of about $3.6 billion last year, they still would’ve burnt ~$5 billion. Their losses this year, with massively decreased revenue due to COVID, could probably be $10+ billion (if they didn’t lay people off). That’d be for non-IPO costs staying static while revenue drops ~35%. And I believe their nest egg is only ~$10 billion, so that’s very roughly around 1 year of runway, much too short. They need to cut a LOT of costs.
