Serve Robotics Inc. (SERV)

Serve Robotics is trading at $3.17, near the bottom of its 52-week range, after a sharp fall over the past year. The stock rose 19.43% over the past week, and its shares jumped 38.79% in the first session after the November 5, 2026 report, when adjusted EPS of -$0.51 beat the -$0.65 estimate. That rebound has not yet changed the longer picture: the price sits well below its 50-day and 200-day moving averages ($3.86 and $6.84), and the stock is down 69.36% over one year. Investors are weighing a business that is growing revenue quickly against losses that remain very large relative to its size.

Serve Robotics reported adjusted EPS of -$0.51 on November 5, 2026, against an analysts' estimate of -$0.65, a beat of 21.54%. The shares rose 38.79% in the first session after the report. That reaction is the largest single move in the earnings record covered here, and it came after a run of mixed results: the August 6, 2026 report matched the estimate at -$0.59 and the shares fell 10.48% the next session. Across the five most recent reports, two beat the estimate and two missed it, and the share price was lower in the first session after four of the five. The November rebound therefore stands out against that record rather than fitting a pattern.

Analysts expect revenue of $9.7M this fiscal year, which would be growth of 265.9%. The business is still significantly unprofitable: the net profit margin is -2,079.02% and the operating margin is -2,158.31%. Analysts' average EPS estimates are -$2.35 for this fiscal year and -$1.92 for next year, so the loss per share is expected to narrow but not to disappear. Return on equity of -70.15% sits well below the sector median of 17.8%.

With a market capitalisation of $277.1M and a price-to-sales ratio of 27.88, the stock trades at a multiple far above the sector median P/S of 4.0. Because GAAP earnings per share over the last 12 months are -$2.61, the P/E ratio is not meaningful. The debt-to-equity ratio of 0.03 means borrowing is a small part of the capital base, which limits balance-sheet stress even while operating losses persist. The company's health score is 3 of 5.

Insider selling and the trading picture Over the last 18 months, insiders recorded 93 sales worth $9.2M and made no open-market purchases. Such sales are often planned in advance or made to cover tax on vesting shares, so they are a weaker signal than purchases would be. Beta of 2.88 against the S&P 500 and a typical daily move of 9.15% mean the shares react strongly to both company news and broad market swings.
