Shares of Hesai Group (NASDAQ: HSAI), a leading LiDAR technology provider, plunged 5.17% in Wednesday's trading session following the release of its first-quarter earnings report and second-quarter guidance that fell short of market expectations. The significant drop reflects growing investor concerns over near-term revenue impacts from tariffs and shifting customer demand.

During the company's earnings call, Hesai's management provided a second-quarter revenue guidance of RMB 680-720 million ($93.7-99.2 million), representing year-over-year growth of 48-57%. However, this outlook factors in potential impacts from evolving tariff situations and the rescheduling of some U.S.-bound robotics LiDAR shipments from Q2 to Q3. CFO Andrew Fan explained, "We have seen some customers front-load or reschedule their orders due to the uncertainty around future policy changes, especially after April."

Despite maintaining its full-year 2025 revenue guidance of RMB 3-3.5 billion, investors appeared wary of the near-term headwinds and competitive pressures facing Hesai. The company addressed speculation about potential customer losses, with CEO David Li emphasizing the high barriers for competitors to displace Hesai as an incumbent supplier. However, the stock's sharp decline suggests that the market remains cautious about Hesai's ability to maintain its market leadership and meet profitability targets in an increasingly competitive landscape.
