Should You Buy Uber Stock Because Its Operating Margin Keeps Climbing?
Uber Technologies (UBER) trades at $73.13, down about 20% over the past twelve months, while the S&P 500 (SPY) returned roughly 19%, and the stock sits at about 72% of its 52-week high. The worry is real: a multiyear $10 billion autonomous-vehicle investment whose income-statement impact management has not yet sized. One number has moved the other way in each of the last three years, and it is the operating margin.

Uber Went From Losing Money On Operations To A Double-Digit Margin
Three years ago that margin was -1.6%. It rose to 5.0%, then 9.5%, and now stands at 12.1% over the trailing twelve months, the high end of its multi-year range; a trend held for three straight years. Part of that climb is definitional, not just operational: a UK business-model change moved certain costs out of cost of revenue, which mechanically lifts the reported margin on top of any real efficiency gain.
Reported profit tells a different story. Net margin is 17.3% over the trailing twelve months, down from 26.7% a year earlier, and it sits above the 12.1% operating margin, so some reported profit comes from below the operating line rather than from operating the business. The operating margin is the cleaner read. Cost cuts are a lever, but a modest one so far; insurance savings are being reinvested rather than banked, and management calls the headcount savings modest, so neither shows up in the trailing margin yet.
Insurance Is Turning Into A Tailwind, And Headcount Costs Are Next
Insurance has been a drag on US mobility for years, and management says it is becoming a tailwind in 2026. Uber is reinvesting the savings back into the market, and trip growth in L.A. and San Francisco beat the rest of the country.
The other piece is headcount, though management calls the savings booked so far modest. Near-universal use of AI-based coding tools among its engineers has doubled code output per engineer on the company’s own early measure, which let Uber slow the pace of engineering hiring. In early September 2026, it went further, cutting about 3,300 jobs, roughly 10% of the workforce, targeting management layers and its micro-teams. None of that is in the trailing-twelve-month margin yet.
Can Uber Keep Widening Its Margin While It Funds Autonomous Vehicles?
It is a fair question, and management has not put a number on the income-statement impact. Rivals chasing the same 2-wheeler supply in Brazil have dented trip volumes, though the business is low-margin and Uber says it is holding share. The bigger item is the $10 billion of autonomous investment, which Uber has said runs over a multiyear period and will land on the income statement, sized for investors as deployment nears.
The widening margin is what funds that investment from the inside. Free cash flow passed $10 billion over the trailing twelve months for the first time in Uber’s history. It ran at about 106% of reported net income, a net income figure that, as noted above, includes gains earned below the operating line, so cash generation is outrunning even that broader profit measure. Uber also bought back about $3.5 billion of its own stock through the first half of 2026. However, it pivoted heavily toward M&A in the second quarter of 2026 and is only now rebuilding the repurchase pace.
The case is narrow. The operating margin widened for three straight years while the share price went the other way. The risk sits on that same line: if the operating margin stops climbing once autonomous costs reach the income statement, the buy case stops with it, and 12.1% is the number to watch when Uber reports the third quarter of 2026.
