Serve Robotics Cuts 2026 Revenue Guidance by Roughly Two-Thirds as Uber Eats Volumes Fade
Serve Robotics delivered the AI small-cap season's sharpest guidance reversal. In results released August 6, the sidewalk delivery robot company reported second-quarter revenue of $3.2 million, up 404% from $642,000 a year earlier and 9% above the first quarter's $2.98 million — and then cut its full-year 2026 revenue outlook to $9 million to $10 million from a prior $26 million.
The company attributed the revision to its largest channel. The reduced outlook 'reflects lower than expected delivery volume through the Company's Uber Eats partnership, including a decline reflected in Q2 results and the removal of projected demand in the second half of 2026,' Serve said in the release. On the earnings call, chief executive Ali Kashani said the shortfall 'was caused by lower-than-expected robot utilization' and that absent improvements to the operating model, 'we don't currently expect that it would make sense to renew our agreement when it expires in early 2027,' according to a transcript published by Investing.com.
Operating metrics show the utilization problem directly. Daily active robots fell to 792 from 812 in the first quarter, and daily supply hours declined to 9,809 from 10,295, per the company's release — a fleet that got slightly smaller and slightly less busy in a quarter when revenue was supposed to be inflecting. Serve has previously described a fleet of roughly 2,000 robots across more than 40 cities, per the Investing.com transcript, underscoring how much deployed capacity is idle relative to demand.
The unit economics remain deeply negative. Serve reported a gross loss of $8.8 million for the quarter, a net loss of $64.1 million and an adjusted EBITDA loss of $44.5 million. The transcript pegs gross margin at negative 271% and non-GAAP loss per share at $0.59 against a GAAP figure of $0.80 — the arithmetic of running a hardware fleet whose fixed costs do not shrink when orders do.
Management paired the cut with reduced spending. Non-GAAP operating expense guidance came down to $140 million to $150 million from $160 million to $170 million, and capital expenditure guidance fell to $15 million to $17 million from roughly $25 million, per the release and transcript. Cash and marketable securities stood at $240.4 million as of June 30 against 86 million shares outstanding, giving the company time to attempt a reset even after a quarter that consumed a large share of that balance.
The strategic argument management offered is diversification. Chief financial officer Brian Read told analysts that 'Serve is building a robotics platform, not a single use delivery fleet,' per the transcript, and the company pointed to software revenue of $933,000 in the quarter — against $2.3 million in fleet services — with recurring revenue exceeding half the total and advertising contributing nearly half of food delivery revenue. A software and advertising mix is less capital-intensive than sidewalk logistics, but it is also currently much smaller.
Investors reacted immediately. The transcript notes shares fell about 11% after hours, from a $5.68 close toward $5.06, against a 52-week range of $4.32 to $18.64. The stock had rallied into the print, with Invezz reporting on August 3 that traders were positioning ahead of results.
The next scheduled catalyst is close. Serve has flagged an August 17 announcement covering a new marketplace partner, additional market launches, its Beacon product and autonomy updates, with a direct customer demand product slated for the fall, per the transcript. Whether a replacement channel can absorb the capacity Uber Eats is no longer filling is now the entire question in front of the company.
