SCHEDULE I

Hesai Group Reports Fourth Quarter and Full Year 2025 Unaudited Financial Results

Quarterly net revenues were RMB1,000.5 million (US$143.1 million)¹
Quarterly lidar shipments were 631,095 units
Quarterly net income was RMB153.2 million (US$21.9 million)

SHANGHAI, China, Mar. 24, 2026 (GLOBE NEWSWIRE) — Hesai Group (“Hesai” or the “Company”) (NASDAQ: HSAI; HKEX: 2525), the global leader in three-dimensional light detection and ranging (lidar) solutions, today announced its unaudited financial results for the three months and full year ended December 31, 2025.

Management Remarks

“2025 was a landmark year as Hesai became the first lidar company to achieve full-year GAAP profitability, while also ranking No.1 in 2025 with over 40% share of the long-range automotive lidar market, according to Gasgoo.” said Dr. Yifan “David” Li, Hesai’s Co-Founder and CEO. “As lidar emerges as the ‘invisible airbag’ for ADAS safety, we have secured design wins with all top ten Chinese OEMs, expanded into the sub-RMB100,000 mass market, captured the multi-lidar L3 inflection point, and accelerated global expansion through partnerships with NVIDIA and others. These milestones are structurally increasing lidar content per vehicle and broadening our total addressable market. Beyond automotive, substantial opportunities are also opening up, where Hesai ranked No.1 across major robotics submarkets, such as humanoid and quadruped robots, robotaxis, robovans, and robotic lawn mowers, according to GGII, Yole Group, and Frost & Sullivan. To fully capitalize on the surging demand across both ADAS and Robotics, we are scaling our annual production capacity to over 4 million units in 2026.”

Dr. Li continued, “As the AI-driven Fourth Industrial Revolution accelerates, Hesai is positioning to become the key enabler of Physical AI – digitizing the real world, redefining how humans and robotics perceive and act. Over the coming months, we will launch new flagship products, each targeting an addressable market worth trillions of RMB, bringing this vision to life and laying the groundwork for our next decade of growth.”

¹ All translations from RMB to USD for the fourth quarter and full year of 2025 were made at the exchange rate of RMB6.9931 to US$1.00, the exchange rate on December 31, 2025, set forth in the H.10 statistical release of the Federal Reserve Board.

"2025 marked a significant milestone for us in both the scale and quality of our financial performance," said Mr. Andrew Fan, Hesai's CFO. "We delivered record net revenues of over RMB3 billion (US$433 million), up 46% year-over-year, while tripling total shipments to over 1.6 million units. Importantly, we also achieved industry-first full-year GAAP net income of RMB436 million (US$62 million) and non-GAAP net income² of RMB551 million (US$79 million) in 2025, driven by robust revenue growth, disciplined cost management, and improved operating leverage through AI-enabled efficiency gains across R&D, manufacturing, and operations. We have also delivered GAAP net income for three consecutive quarters and non-GAAP net income for five consecutive quarters. Alongside this, we also recorded three consecutive years of positive operating cash flow, while our net assets grew to around RMB9 billion (US$1.3 billion)."

Mr. Fan added, "2026 marks a bold new chapter for Hesai. We are raising our outlook for lidar shipments to 3 to 3.5 million units, and will soon launch breakthrough new products that unlock future opportunities, and further advance our vision to empower robotics and elevate lives."

Use of Non-GAAP Financial Measures

To supplement Hesai’s consolidated financial results presented in accordance with GAAP, Hesai uses the following measures defined as non-GAAP financial measures by the SEC: income/loss from operation excluding share-based compensation expenses, net profit/loss excluding share-based compensation expenses, net profit/loss attributable to ordinary shareholders excluding share-based compensation, and per ordinary share net income/loss attributable to ordinary shareholders excluding share-based compensation. The presentation of these non-GAAP financial measures is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. For more information on these non-GAAP financial measures, please see the tables captioned “Unaudited Reconciliations of GAAP and Non-GAAP Results” set forth at the end of this release.

Hesai believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance and liquidity by excluding share-based compensation expenses that may not be indicative of its operating performance from a cash perspective. Hesai believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing its performance and when planning and forecasting future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to Hesai’s historical performance and liquidity. Hesai believes these non-GAAP financial measures are useful to investors in allowing for greater transparency with respect to supplemental information used by management in its financial and operational decision making. A limitation of using these non-GAAP financial measures is that they exclude share-based compensation expenses that have been and will continue to be for the foreseeable future a significant recurring expense in our business. Management compensates for these limitations by providing specific information regarding the GAAP amounts excluded from each non-GAAP financial measure. The accompanying tables have more details on the reconciliations between GAAP financial measures that are most directly comparable to non-GAAP financial measures.
