Uber Technologies (NYSE: UBER) has exited its investment in Serve Robotics (NASDAQ: SERV), selling its entire remaining stake in the autonomous delivery robot company. The disclosure, made in a regulatory filing on Friday, came as a surprise to Serve Robotics, which stated it was unaware of the exit until the news surfaced publicly.

The dissolution of the financial tie marks a significant shift in the partnership that began in 2022 and was expanded in May 2023 to include up to 2,000 sidewalk robots for use on the Uber app across several U.S. cities. Serve Robotics CEO Ali Kashani indicated during the recent second-quarter earnings call that the two companies hold "differing views" regarding their shared autonomous fleet and potential operating models. Bloomberg reported that Serve hinted the commercial deal will not be renewed after its expiration in 2027.

Operational Reversal

The strategic divergence coincides with a break in Serve’s growth trajectory on the Uber platform. Kashani noted that delivery volume through Uber had grown for 17 consecutive quarters from the first quarter of 2022 through the first quarter of this year. However, that trend reversed for the first time in the second quarter, driven by lower-than-expected robot utilization.

Despite the setback with Uber, Serve reported that deliveries with another food delivery partner rose approximately 50% in the recent quarter. Uber maintains partnerships with more than 30 autonomous vehicle companies, including firms in which it holds investment stakes.

Financial Impact and Guidance Cut

Serve Robotics reported second-quarter revenue of $3.28 million, missing the Street consensus estimate of $3.49 million. While the company posted a lower loss per share than analysts expected, it significantly reduced its full-year outlook. Serve lowered its 2026 revenue guidance to a range of $9 million to $10 million, a sharp decline from its prior guide of $26 million for the fiscal year. The company attributed the revision to lower-than-expected delivery volume through its Uber Eats partnership.

Kashani emphasized that Serve is driving innovation in last-mile delivery as its scaled robot fleet powers deliveries across multiple verticals. The CEO stated the company is seeking more diversified revenue streams and new monetization opportunities.

What the Numbers Show

The drastic reduction in Serve Robotics’ full-year revenue guidance—from $26 million to a range of $9 million to $10 million—highlights a heavy dependency on the Uber channel for top-line growth. With Uber representing the primary volume driver for 17 consecutive quarters prior to Q2, the simultaneous reversal in Uber delivery volumes and the subsequent exit of Uber as a shareholder suggest that near-term revenue recovery may require substantial diversification away from this single partner. The 50% growth with an alternative food delivery partner provides a counterbalance but remains insufficient to offset the magnitude of the guidance cut without further scale.

Market Reaction

Serve Robotics stock traded at $5.04 on Wednesday, up 2.9%. The stock has declined 57.4% year-to-date, trading within a 52-week range of $4.32 to $18.64.

Uber originally acquired Serve Robotics’ division when it bought Postmates for $2.65 billion in 2020. The unit, initially known as Postmates X, was spun off as Serve Robotics in 2021. Five years later, Uber’s ownership stake is fully divested, and the operational partnership appears to be winding down.

Uber Technologies Inc. shares surged 6.12% to $74.78 on Friday, reversing earlier declines following its second-quarter earnings report. The rally was driven by positive analyst commentary on the company’s autonomous vehicle (AV) ecosystem and drone delivery ambitions, despite several firms trimming price targets. While Q2 revenue of $14.19 billion missed consensus by $50 million, strong operational metrics and a clear strategic pivot toward automation bolstered investor confidence.

Analyst Reactions and Price Targets

Analysts maintained constructive outlooks but adjusted valuations downward. DA Davidson retained a Buy rating but cut its price target to $100 from $107. Cantor Fitzgerald kept an Overweight rating while lowering its target to $90 from $98. Needham reiterated a Buy rating with a $109 target, highlighting solid execution in the Mobility segment. Investors are closely monitoring how Uber balances near-term earnings pressure with long-term autonomy investments.

Financial Performance Recap

For Q2, Uber reported revenue of $14.19 billion, up 12% year over year, against an estimate of $14.24 billion. Adjusted earnings per share hit 81 cents, in line with expectations. Gross bookings grew 24% to $58.02 billion. GAAP net income rose 30% to $2.39 billion, and adjusted EBITDA increased 33% to $2.82 billion. The company generated $2.79 billion in free cash flow for the quarter.

Autonomous Delivery Expansion

CEO Dara Khosrowshahi emphasized the potential of ultra-fast food delivery, describing 10-to-15-minute service as a "magical experience." Uber is expanding its autonomy strategy beyond robotaxis to include drones through partnerships with companies like Flytrex. This diversification aims to capture new market segments and enhance platform efficiency. The company also noted that over 8 million World Cup tourists used Uber services during the quarter, boosting Mobility demand.

Market Outlook

Third-quarter guidance for adjusted EPS of 84 to 88 cents fell short of the 89-cent consensus, contributing to initial premarket declines. However, the subsequent rally suggests investors are prioritizing the long-term value of Uber’s AV and drone initiatives over short-term misses. The company continues to repurchase shares, buying back approximately $518 million in Q2.
