Thank you, Yuanting, and thank you, everyone, for joining our call today. Let's start with the big picture. We're pleased to deliver the strongest quarterly financial performance in our history. In the first quarter, our net revenues were up 73% year-over-year to a new record high, and our industry-leading gross margins increased quarter-over-quarter to 38%, up from 30% last quarter.
Expense-wise, excluding share-based compensation, R&D remains steady and our product lines and organizational structure are approaching maturity. As a result, and most excitingly, we achieved non-GAAP profitability and positive operating cash flow in the first quarter, demonstrating our tremendous future profitability prospects.
Mobilization is more encouraging than the recognition from our customers. Having delivered more than 135,000 LiDAR units to date, Hesai has become the most commercially successful LiDAR manufacturer in terms of shipments in both Robotaxi and ADAS market.
We stand out from others for two reasons. First, our proven automotive-grade product quality built upon our methodology of having in-house manufacturing as a crucial part of the R&D to enable rapid iteration of our product. And second, in addition to taking advantage of economics of scale, we have committed to continued innovation on our proprietary ASIC platform, allowing more affordable solutions via highly integrated components. Since 2017, we've gone through 4 generations of our proprietary ASIC development with contributions from more than 150 dedicated semiconductor staff. We're proud to be uniquely positioned to offer LiDAR solutions with better combination of high performance, high-quality and affordability.
Now I'd like to share some exciting first quarter business updates. First, we're thrilled to have the privilege of collaborating with 11 pioneering OEMs in the industry, a multiyear ADAS contract, including Li Auto, a leading Chinese EV maker, as well as another top-selling EV maker in China. We're also working with a leading consumer electronics maker in China on their planned EV debut and 2 of the largest automakers in China, including Taiwan and many other leading auto OEMs.
In the first quarter, we continued to gain momentum in signing more contracts in the domestic market. We were selected by Li Auto for its new fully battery electric vehicle platform and by Jidu, a joint venture between Baidu and Geely Group, for its new EV model. We also initiated a partnership with a new customer, SERES, a leading EV maker in China, whose new car models will be shipped with our AT128 LiDAR. As the China EV market is growing exponentially, we'll be shipping to 6 OEMs by end of 2023 and 11 by end of 2024.
Hesai has a global vision since its inception. With our proven ability to ship large volumes of high-quality ADAS sensors, we already advanced in 8 RFI and RFQs with 5 leading global OEMs who are expecting a new round of sourcing decisions to materialize in the next coming 12 months.
In the autonomous mobility market, we continue to lead as the best-in-class player. We recently signed the largest Robotaxi contract in our company's history. According to an independent third-party report, we are the primary LiDAR provider for 12 out of the world's top 15 autonomous driving companies with nearly 60% global market share.
Next, we're dedicated to in-house manufacturing as we see this as the only way to meet automotive-grade standards at this early stage of development in ADAS market. During the first quarter, we completed the first successful production sample from our Hertz center, a dedicated manufacturing center in Hangzhou, which takes automation to the next level. Featuring over 90% automation, Hertz produces 1 LiDAR every 45 seconds. With an optimized design, the AT series produced at Hertz would improve our ADAS gross margin as it reaches the economy of scale in manufacturing and utilization.
Additionally, our advanced R&D and intelligent manufacturing center in Shanghai, Maxwell, is a true innovation center for new products to be designed, tested, calibrated under one roof before they are handed over to mass production. Its construction is scheduled to be completed in Q3 of this year.
Leveraging the development of our latest ASIC Gen 4.0, we're able to continue releasing state-of-the-art products that meet the ever-increasing needs of both performance and design aesthetics while keeping them affordable. ET25, a groundbreaking in-cabinet LiDAR, featuring an extremely thin profile of only 25 millimeter in height with extended range and enhanced resolution, was recently released at the Shanghai Auto Show. ET25's revolutionary concept is attracting interest from OEMs globally, who are demanding extremely miniaturized LiDAR behind the windshield to achieve both an aesthetically pleasing exterior vehicle design and optimal air dynamics. To conquer the great challenges of putting LiDARs behind the windshield, we team up with global automotive glass leader, Fuyao Group, to create a specialized windshield to enhance the laser transmittance efficiency by up to 3x.
Finally, before I hand it over to Louis for a deeper look at the financial numbers, I wanted to congratulate the whole team from operations to product innovation on an exceptional quarter. With non-GAAP profitability and positive operating cash flow in the first quarter, which showcased our potential for continued growth momentum, we remain confident in our ability to seize development opportunities in both ADAS and the AM market, bringing a higher level of safety to the future of intelligence driving system.
Now I'll turn over the call to Louis to share more details on our financial performance and outlook. Louis, please go ahead.
