Shares of Serve Robotics Inc. (NASDAQ: SERV) tumbled 15.96% in after-hours trading following the release of its second-quarter earnings report. The robotics company's stock took a hit as it reported a larger-than-expected loss per share, overshadowing a revenue beat.

Serve Robotics reported a quarterly loss of $0.24 per share, missing analysts' consensus estimate of a $0.21 loss by 12.68%. Despite the earnings miss, the company's revenue showed significant growth, coming in at $642,000. This figure surpassed the analyst consensus estimate of $624,800 by 2.75% and represented a 37.07% increase from the same period last year when the company reported sales of $468,380.

While the revenue growth is encouraging, investors appear to be focusing on the bottom line miss. The wider-than-expected loss suggests that Serve Robotics may be facing challenges in controlling costs as it scales its operations. As the company continues to navigate the competitive robotics industry, market participants will likely be closely watching its ability to narrow losses while maintaining strong top-line growth in future quarters.
