Serve Robotics (SERV) experienced a surge exceeding 14% in Wednesday’s premarket hours following a one-two punch of positive developments: a fresh partnership announcement coupled with fourth-quarter financial results that outperformed analyst expectations.
The autonomous delivery company revealed a collaboration with White Castle that will enable the iconic burger chain’s menu items to reach customers through Uber Eats (UBER). Customers placing orders within Serve’s operational territory may now receive their food via the company’s self-navigating sidewalk robots.
This agreement broadens Serve’s presence within the Uber Eats ecosystem, a platform that has become instrumental to the company’s distribution strategy.
CEO Ali Kashani described the collaboration as a significant achievement. “White Castle is a legendary brand that helped define convenient, fast meals, and we’re thrilled to bring that legacy into the future,” he stated.
“Seeing a Serve robot roll down the sidewalk with a Crave Case will soon feel like a natural extension of the White Castle experience,” Kashani added.
Fourth-Quarter Performance Exceeds Forecasts
Beyond the White Castle announcement, Serve simultaneously released its fourth-quarter financial performance — which outpaced analyst projections.
The company reported a per-share loss of -$0.46, surpassing Wall Street’s expectations. Revenue reached $0.88M, likewise exceeding the consensus forecast.
Given that Serve remains in its early development phase, revenue figures remain modest. Nevertheless, surpassing estimates on both metrics carries significance for investor sentiment.
2026 Revenue Forecast Upgraded
Potentially more significant than the Q4 figures was the company’s revised forward guidance. Serve elevated its full-year 2026 revenue projection to roughly $26M.
This figure exceeds the previous Wall Street consensus estimate of $25.28M.
Upward guidance revisions typically capture market attention. They signal management’s growing confidence in the business trajectory through the remainder of the year.
The White Castle agreement factors into this improved outlook. Incorporating a nationally recognized fast-food brand increases the potential order volume processed through Serve’s autonomous fleet.
Serve’s robotic delivery vehicles navigate sidewalks to complete final-mile deliveries across urban environments. The fleet currently maintains active operations throughout sections of Los Angeles.
The strategic alliance with Uber Eats has served as a foundational element of Serve’s market penetration approach, with the White Castle announcement representing the relationship’s continued evolution.
SERV shares climbed substantially during Wednesday’s premarket trading, responding positively to both the earnings outperformance and the partnership revelation.
The 2026 revenue target of approximately $26M represents substantial growth for an enterprise that generated $0.88M during the fourth quarter alone.
