Hesai Group (HSAI) recently put its next generation lidar technology in the spotlight, unveiling the Picasso 6D full color lidar ASIC and ETX lidar series for autonomous vehicles and robotics at its 2026 Technology Open Day.

Despite the excitement around its new lidar platforms, Hesai Group’s share price has been volatile, with a 7.37% 1 month share price return but a 7.79% 3 month decline. At the same time, a 1 year total shareholder return of 20.34% and a 3 year total shareholder return of about 13x point to stronger longer term momentum.

With Hesai sharing new lidar platforms, a roughly 23% intrinsic discount estimate, and a 38% gap to analyst targets, the key question is simple: is the stock still mispriced or already reflecting future growth?

Most Popular Narrative: 18.7% Undervalued

Hesai Group’s fair value in the most followed narrative sits at $27.07 versus the last close at $22.01, framing the stock as materially discounted in that lens.

Hesai’s valuation is increasingly supported by tangible execution and forward visibility rather than expectations alone. Following strong 4Q25 results, management reiterated a confident outlook, underpinned by stable gross margins driven by scale efficiencies and ongoing technology-led cost reductions. This combination is critical, as it signals that growth is not coming at the expense of profitability but alongside improving unit economics.

The narrative leans heavily on rapid volume growth, widening end markets, and a shift toward a broader sensing platform. It quietly bakes in ambitious assumptions around earnings compounding, margin resilience, and how far lidar plus robotics can scale together.

Result: Fair Value of $27.07 (UNDERVALUED)

However, you still need to factor in risks, such as Hesai’s high exposure to Mainland China demand and the possibility that lidar adoption or robotics volumes fall short.

Another View: Earnings Multiple Sends A Different Signal

While the SWS fair value work points to about a 23% discount, the current P/E of 53.9x is well above the fair ratio of 39.9x, the US Auto Components average of 18.7x, and the peer average of 19.7x. That kind of gap suggests valuation risk if expectations slip, so which reference point do you trust more: the fair value estimate or the earnings multiple comparison?
