RiverPark Large Growth Fund stated the following regarding Uber Technologies, Inc. (NYSE:UBER) in its fourth quarter 2025 investor letter:
“Uber Technologies, Inc. (NYSE:UBER): UBER was a detractor in the fourth quarter following its third-quarter 2025 earnings report, which delivered strong operating performance but was met with a muted market reaction. Gross Bookings and adjusted EBITDA both came in near the high end of management’s guidance, driven by accelerating demand across both Mobility and Delivery. Total trips grew 22% year-over-year, the fastest pace since 2023, supported by record Monthly Active Platform Consumers of 189 million, up 17% year-over-year, and continued gains in trip frequency. Mobility and Delivery bookings growth both accelerated, aided by affordability initiatives, expansion in lower-density geographies, and continued momentum in Uber One, which now accounts for roughly two-thirds of Delivery Gross Bookings. Management’s fourth quarter Gross Bookings outlook was ahead of consensus expectations, signaling continued operating momentum.
However, investor focus shifted to commentary around reduced margin expansion as the company steps up investment in growth initiatives, including autonomous vehicle partnerships, platform innovation, and commerce expansion, which weighed on near-term sentiment despite strong results. In addition, sentiment was also pressured by the apparent success of Tesla’s robotaxi testing program in Austin, Texas, which reignited concerns that autonomous vehicle adoption could eventually disrupt Uber’s core ride-hailing economics by reducing driver-related costs and introducing new, vertically integrated competitors.
We continue to view Uber as a leading global platform benefiting from secular shifts toward on demand transportation, delivery, and local commerce. We believe the robotaxi ecosystem will ultimately include multiple players, and Uber is well positioned to offer many, if not all, of these autonomous mobility options alongside human-driven rides on its platform. As robotaxi adoption expands, we expect the total addressable market for on-demand transportation to grow meaningfully, supporting long-term volume and revenue growth. With improving unit economics, a growing advertising business, and strong cash flow generation, Uber remains well positioned.”
