Uber (UBER): $10 Billion Free Cash Flow and a Robotaxi Doubt

Uber earned more than $10 billion of free cash flow over the last twelve months, the first time it has crossed that line, and the stock trades around $70.50 as I write this, roughly 30.9% below its 52-week high of $102. Those two facts do not fit together comfortably. A business that throws off that much cash normally does not sit at 15.5 times trailing earnings with a market value of $144.0 billion unless the market has decided that something about the future is broken.

I think the market has picked one thing: robotaxis. My view is that the core business is worth more than the current price implies, that the autonomous-vehicle worry is real but partly a story about timing, and that the risk is not that Uber fails but that its cash flow is slowly reclassified from “platform toll” to “middleman about to be cut out.” Everything below is meant to test that sentence.

What the second quarter actually showed

Start with the second-quarter release on Uber’s investor site. Gross bookings grew 22% to a record of about $58.0 billion. Free cash flow for the quarter was $2.8 billion, and the trailing twelve months went past $10 billion. Revenue was $14.2 billion, up 12% from a year earlier, according to the same release and the coverage of it.

Read the gap between those growth rates. Bookings rose 22% while revenue rose 12%. Revenue is what Uber keeps after paying drivers and couriers in most of its business lines, so a widening gap means either more of the volume is coming from lines where Uber books less revenue per dollar, or that mix and accounting shifted. I cannot tell you which from the headline numbers alone, and I would not pretend to. What I can say is that anyone valuing the stock off revenue will see a slower company than anyone valuing it off bookings, and that disagreement is part of why the argument is noisy.

The stock reacted with a drop of -5.3% on the report date of 2026-08-05. Uber’s average post-earnings move over recent quarters has been about 6.0%, so this was a normal-sized reaction, not a panic. I treat those moves as a measure of how jumpy the shares are, not as a forecast.

Metric	Value	Context
Price	$70.50	52-week range $65 to $102
Market value	$144.0 billion	about 2.6 times sales versus a five-year average of 3.4
Trailing P/E	15.5	trailing EPS $4.56
Forward P/E	17.8	forward EPS estimate $3.95
Revenue, 2025	$52.0 billion	up 18% from $44.0 billion in 2024
Latest quarter revenue	$14.2 billion	up 12% year over year
Q2 gross bookings	about $58.0 billion	up 22%
Trailing free cash flow	above $10 billion	first time over that mark

Why trailing earnings mislead here

Look at the two P/E figures in that table. Trailing earnings per share of $4.56 give 15.5 times, while the forward estimate of $3.95 gives 17.8 times. A forward EPS lower than trailing EPS is odd for a company growing bookings at 22%. The implied change in the data is -13%.

I do not read that as a collapse. Trailing GAAP earnings at companies like this can be lifted by one-off items such as tax adjustments or gains on investments, and analysts’ forward numbers usually strip them out. So the trailing figure is probably flattering and the forward figure is closer to what the operating business earns. That is an inference, not something I verified line by line in the filing. If you want to check it, the Uber filings on SEC EDGAR show the reconciliation between operating income and net income, and the gap is worth ten minutes.

Operating income in the last fiscal year was $5.6 billion, a margin of 11%, against a net margin of 19%. Net income above operating income by that much is the tell.

That is exactly why free cash flow is the number I lean on for Uber. Cash is harder to dress up. Twelve months of more than $10 billion against a market value of $144.0 billion is a free cash flow yield in the neighborhood of 7% before any adjustment for stock compensation, which for a company of this type is a real cost that free cash flow does not subtract. Even after a generous haircut for that, the yield is not the kind of number a fading business carries.

The Waymo crack

Uber’s strategic pitch for autonomous vehicles has been simple: it is the demand platform. Riders are already in the app, so whoever builds the cars needs Uber to fill them. In Austin and Atlanta that pitch was tested with Waymo, and the pitch looked good on paper.

Then came the news, covered by CNBC in July. Waymo said it will launch its own app in Austin and Atlanta in January 2028, ending exclusivity with Uber in both cities. Reporting on the arrangement says the current Waymo fleet stays on the Uber app through at least May 2028, and that Uber gains the freedom to put other autonomous vehicles on its platform in those cities. Waymo, by that reporting, already operates in 11 US metro areas without Uber and handles more than 500,000 paid rides a week.

That last figure is the one that matters. If Waymo can build ridership on its own in eleven metros, then the argument that it needs Uber for demand gets weaker city by city. I read the Austin and Atlanta split as the first visible instance of a partner deciding to go direct once it has enough scale. It may not be the last.

I want to be fair to the other side, though. Two years is a long time in a business where the vehicles are scarce and expensive. Waymo’s own app has to acquire riders from scratch in those cities, and Uber gets to bring other vehicle makers onto its network. Losing exclusivity is not losing the cities. It is a change in bargaining power, and that matters for the share of each fare that Uber keeps.

Delivery and ads, the quiet cash source

Robotaxis grab headlines, but I would expect only a sliver of that $58.0 billion in bookings to come from autonomous vehicles; I have not seen a figure. The bulk is ordinary rides and delivery. I did not verify a current split of bookings between mobility and delivery for this post, so I will not quote one, and the point stands without it: the cash flow being valued today comes from human drivers and couriers, and the robotaxi question is about what happens to the growth and the margin a few years out.

Advertising inside the delivery app is the piece I like most, in principle. Restaurants and retailers pay to be seen once the logistics network exists, and that revenue does not need a new courier for each dollar. I do not have a verified figure for Uber’s advertising run rate in this report, so treat that as a reason the margin could keep improving, not as a measured fact. Check the segment disclosure before leaning on it.

The comparison that helps me is with other platforms that turned a large user base into cash. I looked at Meta’s cash flow last quarter, where heavy spending on new infrastructure pushed free cash flow down even as revenue grew 28%. Uber is the mirror image so far: revenue growing more slowly than bookings, but cash flow expanding. The question for Uber is whether it will be forced to spend like Meta on a technology it does not control.

What the price asks you to believe

At around $70.50, Uber is valued at 2.6 times sales, compared with a five-year average of 3.4 for its own history. The discount to its own past is real. A stock rarely trades below its own average multiple while growth is accelerating unless investors expect the growth to end or the margin to shrink.

Analysts are far more upbeat than the market. Among 31 analysts in the data, 90% rate the stock a buy, and the average price target is $104, which implies about 47% upside from here. The range runs from $72 at the low end to $125 at the high end. Even the lowest target sits about 2% above the current price. I would not treat targets as evidence. They move after prices do, and consensus this bullish after a 31% drawdown tells me analysts are anchoring on the operating results while the market is anchoring on the autonomous-vehicle story. Both can be right for a while.

The framing I use: at this price, a buyer is paying for roughly a decade of the current business with a modest allowance for autonomy to take some of it. If I assume free cash flow simply stays flat at about $10 billion and I discount it at a typical equity return, the current market value of $144.0 billion is not obviously expensive, and it does not need heroic growth to work. It needs the cash flow to survive.

The case against this view

Here is what would prove me wrong, in concrete terms. Suppose that within two or three years autonomous vehicles become a meaningful share of urban ride volume, and the operators of those vehicles decline to route demand through Uber. Then the trailing cash flow of more than $10 billion is a peak, not a base. In that world Uber’s revenue per ride would fall as it competes with operators that own the vehicle, the rider and the app, and the multiple should stay low.

There is also a quieter risk that I cannot size: regulation and labor rules that change the economics of the human-driver network before autonomy arrives. That would hit the cash flow directly.

I also have to admit what I do not know. I do not know how fast autonomous ride volume will scale, how much of Uber’s trailing cash flow comes from cities where autonomous competitors are already present, or how much stock compensation is hiding behind the free cash flow number. Any of those could change the answer.

Two numbers to watch

If I were monitoring this position, I would watch two things after the next report. The first is trailing free cash flow: staying above $10 billion says the engine is intact, and a slide toward $8 billion would say the bookings growth is being bought with cash. The second is the count of cities where Uber still has an exclusive or preferred autonomous partner. Right now that count is shrinking at the margin, and I would like to see it stop shrinking, or see Uber add partners other than Waymo, before I gave the robotaxi risk a lower weight. For comparison, I laid out a similar test for a different kind of company in my note on Ford’s split between profit and burn: find the number that separates the old business from the new bet, and follow it.

My call: the stock is priced for a mild version of the robotaxi threat and the cash flow is being valued as if it were less durable than the results suggest. I would want the price to stay near its current level with free cash flow above $10 billion for two more quarters before I called that an opportunity, because the risk I cannot measure is the one that decides it.
