SO WHAT: If you purchased Hesai securities you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.

WHAT TO DO NEXT: To join the Hesai class action, go to https://rosenlegal.com/submit-form/?case_id=13347^[1] or call Phillip Kim, Esq. toll-free at 866-767-3653 or email pkim@rosenlegal.com^[2] or cases@rosenlegal.com^[3] for information on the class action. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than June 6, 2023. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.

WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources or any meaningful peer recognition. Many of these firms do not actually litigate securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered hundreds of millions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs' Bar. Many of the firm's attorneys have been recognized by Lawdragon and Super Lawyers.

DETAILS OF THE CASE: According to the lawsuit, the IPO Registration Statement contained false and/or misleading statements and/or failed to disclose that: (1) Hesai Group's gross margin decrease was caused by a lower in-house utilization rate; (2) Hesai Group's gross margin was 30% for the fourth quarter-which was completed over a month before the date of the amended registration statement; and (3) as a result, defendants' public statements were materially false and misleading at all relevant times and negligently prepared. When the true details entered the market, the lawsuit claims that investors suffered damages.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor's ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.
