Yes. That’s why they’re laying people off, and why Uber stock is up in after hours trading. Because of these layoffs, their margins have actually improved. Doesn’t make things any better for the people who find themselves without a job, though.
This is older analysis [1] but Uber is profitable on each ride in their biggest markets until you deduct the OPEX of the main co. The burn of sales, marketing, engineering, support, their rider safety team, the driver inspection and on boarding centers, leases, etc all continue on with or without riders.
In many ways they're worse, especially specialized test equipment and protocol analyzers, because they're designed to evaluate the very thing that goes obsolete.
