Serve Robotics operates a fleet of sidewalk delivery robots born out of Uber’s 2021 spinoff, and the serv stock story now turns on one gap: fast fleet growth against unproven per-delivery economics.
Serve Robotics’ Fleet Footprint: 2,000 Robots and a Sequential Dip
Serve Robotics has deployed more than 2,000 robots across the United States since spinning off from Uber in 2021, reaching approximately 3 million people and supporting delivery for more than 4,000 restaurants, per the August 6, 2026 earnings release.
Daily active robots reached 792 in Q2 2026, roughly five times the 160 reported in Q2 2025. That figure slipped from 812 in Q1 2026, a sequential decline the earnings release does not explain.
Daily supply hours followed the same pattern: 9,809, down from 10,295 sequentially but far above the 1,723 recorded a year earlier.
One caveat for serv stock readers. Since Q1 2026, the daily active robots count blends outdoor sidewalk units with indoor hospital robots gained through the Diligent Robotics acquisition, so it no longer isolates the sidewalk fleet.
Serve sits among robotics stocks building physical AI, though its wheeled units differ from the walking, general-purpose machines pursued by humanoid robot stocks.
Q2 Revenue of $3.2 Million Against $12 Million in Cost of Revenue
Serve Robotics reported Q2 2026 revenue of $3.2 million, up 404% from $642,000 a year earlier and up 9% from $2,984,000 in Q1 2026, per the company’s Q2 2026 10-Q filed with the SEC. Fleet services, which covers delivery, branding, and data monetization, contributed $2,305,000; software services added $933,000.
Cost of revenues reached $12.0 million in the same quarter, nearly four times total revenue. That line covers personnel time, robot depreciation, developed-technology amortization, and network and data costs, per the 10-Q.
Q2 net loss totaled $64.1 million, up from $20.9 million a year earlier, with $14.7 million of stock-based compensation and $6.6 million of combined depreciation and amortization inside that figure. Adjusted EBITDA came to negative $44.5 million.
Advertising made up nearly half of food delivery revenue, and recurring revenue exceeded half of total revenue, per the earnings release. The 10-Q discloses no per-delivery cost figure, so unit economics cannot be calculated from the filing.
What Partner Concentration Means for Serv Stock
Serve Robotics cut its FY2026 revenue guidance to $9 million to $10 million, citing “lower than expected delivery volume through the Company’s Uber Eats partnership,” and reduced second-half demand, per the August 6 earnings release.
The Q2 2026 10-Q shows concentration shifting, not disappearing. Customer A held 11% of revenue, down from 31% a year earlier. Customer B reached 22%, with no prior-year figure.
A customer that made up 39% of revenue in Q2 2025 and 46% of revenue in the first half of 2025 fell below the 10% threshold in Q2 2026. The filing names customers only by letter.
DoorDash-linked revenue grew nearly 50% sequentially, per the earnings release, and an August 17 release added Grubhub, launching in Chicago, Los Angeles, and Alexandria, plus new DoorDash markets in Washington, DC, and San Jose.
Serve also signed seven hospital contract extensions and added two hospitals in the first half.
Cash and marketable securities stood at $240.4 million against $84.7 million in six-month operating cash use, with roughly 86 million shares outstanding. How long that cushion lasts is the same question that hangs over drone stocks and other pre-profit autonomy names.
The next 10-Q will show whether daily active robots resume growth after the Q1-to-Q2 dip, whether cost of revenue narrows, and how Grubhub and expanded DoorDash volume shift the platform mix away from Uber Eats.
