Serve Robotics heads into the back half of May carrying a paradox: Q1 results beat estimates, the company held full-year guidance, yet the stock still fell more than 8% on the day of the print and has shed another 4% this week.
The borrow market tells the clearest story about where conviction sits. Short interest has climbed to 28.8% of the free float — up roughly 14% over the past month — and availability remains extremely tight, with the lending pool running at approximately 94% capacity. On May 7, the day of the earnings release itself, availability briefly hit 100%, meaning every share in the lending pool was lent out simultaneously. Cost to borrow has jumped 31% over the past week to about 24.5% annualised. Shorts are not retreating despite elevated carry costs; they are paying up to hold positions. Options traders, by contrast, have turned less defensive. The put/call ratio has drifted down to 0.46 from above 0.59 in mid-April, sitting modestly below its 20-day average — suggesting options participants are leaning bullish even as the lending market remains squeezed. The two signals are pulling in opposite directions.
The analyst community leans positive but has sharpened its pencils post-earnings. Ladenburg Thalmann on May 13 raised its target from $15 to $16.60 while keeping a Buy. Freedom Broker moved the other way on the same day, downgrading to Hold with an $18 target — a signal that the beat may not have been enough to justify the prior optimism at current prices. Guggenheim initiated with a Buy and a $13 target back in April, while Cantor Fitzgerald kept Overweight earlier in the spring but trimmed its target to $16. The mean target across covering analysts runs around $18, roughly double the current $8.76 price. That gap is hard to ignore, but it partly reflects a company burning cash with negative earnings — P/E and EPS ratios are meaningfully negative — and an EV/EBITDA that similarly reflects pre-profitability economics. The bull case rests on a projected $60–$80 million revenue run rate from 2,000 Gen3 robots; the bear case centres on an unproven technology platform and the shadow cast by Nvidia's earlier decision to divest its stake.
The insider picture adds a layer of nuance. CEO Ali Kashani, President Touraj Parang, and CFO Brian Read all sold shares on May 6 and May 7 — the day of and the day after the earnings print. The amounts are small in absolute dollar terms (the CEO's two-day total was roughly $245,000), and the pattern looks consistent with a scheduled programme rather than a directional call. Net insider flow over the past 90 days is actually positive at about $968,000 on a net-shares basis, which muddles any straightforward read. Institutional holders include BlackRock and Vanguard as the two largest passive holders, each of whom added materially in recent quarters. Uber Technologies holds just under 2.1 million shares — a strategic stake that gives the company a credible distribution partner and adds a layer of commercial credibility to the bull thesis.
The most recent earnings reaction is the fresh data point. Q1 revenue of $3.0 million beat the $2.8 million consensus, and the company reaffirmed its full-year $26 million sales guide. The stock still dropped 8.5% the following session. That reaction pattern — beat, hold guidance, sell off — points to a market that was positioned for something more transformative. The ORTEX short score of 83.6 out of 100 ranks among the most elevated readings in the universe and has barely moved all week, suggesting the short thesis has not been shaken by the earnings beat.
The next scheduled earnings event falls on June 17. Between now and then, the key variable is whether cost-to-borrow pressure and continued short-interest growth force any covering, or whether the stock's inability to rally on a beat keeps adding fuel to the bear side.
