I was curious about the stark discrepancy between your numbers and the parent's, so I did some quick research.
I think you're both kind of right. Reuters writes:
>In 2015, Uber passengers were paying only 41 percent of the actual cost of their trips, according to an analysis by transportation industry consultant Hubert Horan, based on financial statements from Uber. [0]
Of course that's four years ago. What about 2018 numbers? An interesting article makes some allegations about Uber deliberately inflating their profits [1] and making it difficult to tease apart the details:
>When Uber abandoned its failed Chinese, Russian and Southeast Asian operations, the dominant local companies gave Uber equity and debt instruments to partially compensate it for providing them an easier path to market dominance. These non-tradeable instruments only exist because of Uber’s decision to discontinue operations, but Uber includes their $5 billion value in “Net Income From Continuing Operations”
>The current accounting value of these assets is based entirely on Uber’s judgement as to what paper issued by companies currently losing massive amounts of money might be worth someday. [5] If one takes Uber’s judgements at face value, one could conclude that Uber’s only profitable activity is getting paid off for discontinuing staggering unprofitable markets.
..as well as..
>Lyft’s IPO prospectus presented ridesharing unit revenue data but Uber did not. Uber only presented the sum of car service and food delivery trips, so prospectus readers couldn’t figure out what customers were paying for the two services separately, or how prices for the two services have changed. The combined data suggest that both growth rates and pricing was declining in the second half of 2018, but prospectus readers have no way to identify the underlying problems, or whether those problem are likely to get worse.
I think I have to point out that your link at [1] uses Uber's IPO P/L numbers (which include their sale of some foreign holdings) which worked out to a profit of ~987 Million in 2018, but their past financial statements have purposefully excluded the income from those sales in their revenue and P/L numbers. (Uber does not typically use GAAP numbers for exactly this reason)
