THIS NOTICE WAS AUTHORIZED BY THE COURT. IT IS NOT A LAWYER SOLICITATION. PLEASE READ THIS NOTICE CAREFULLY AND IN ITS ENTIRETY.

YOU ARE HEREBY NOTIFIED that a hearing will be held on December 2, 2024, at 10:30 a.m., before the Honorable Roger T. Benitez at the United States District Court for the Southern District of California, Edward J. Schwartz United States Courthouse, 221 West Broadway, San Diego, CA 92101, to determine whether: (1) the proposed settlement (the “Settlement”) of the above-captioned Litigation as set forth in the Stipulation of Settlement (“Stipulation”)¹ for $189 million in cash should be approved by the Court as fair, reasonable, and adequate; (2) the Judgment as provided under the Stipulation should be entered dismissing the Litigation with prejudice; (3) to award Plaintiffs’ Counsel attorneys’ fees and expenses out of the Settlement Fund (as defined in the Notice of Pendency and Proposed Settlement of Class Action (“Notice”), which is discussed below) and, if so, in what amounts; (4) to award payments pursuant to 15 U.S.C. §78u-4(a)(4) in connection with Plaintiffs’ representation of the Settlement Class and, if so, in what amounts; and (5) the Plan of Allocation should be approved by the Court as fair, reasonable, and adequate.

There exists the possibility that the Court may decide to conduct the Settlement Hearing by video or telephonic conference, or otherwise allow Settlement Class Members to appear at the hearing by telephone or videoconference, without further written notice to the Settlement Class. In order to determine whether the date and time of the Settlement Hearing have changed, or whether Settlement Class Members must or may participate by phone or video, it is important that you monitor the Court’s docket and the Settlement website, www.TuSimpleSecuritiesSettlement.com, before making any plans to attend the Settlement Hearing. Any updates regarding the Settlement Hearing, including any changes to the date or time of the hearing or updates regarding in-person or telephonic appearances at the hearing, will also be posted to that website. Also, if the Court requires or allows Settlement Class Members to participate in the Settlement Hearing by telephone or videoconference, the access information will be posted to the Settlement website, www.TuSimpleSecuritiesSettlement.com.

IF YOU PURCHASED OR OTHERWISE ACQUIRED TUSIMPLE SECURITIES BETWEEN APRIL 15, 2021 AND DECEMBER 20, 2022, INCLUSIVE, YOUR RIGHTS ARE AFFECTED BY THE SETTLEMENT OF THIS LITIGATION.

To share in the distribution of the Net Settlement Fund, you must establish your rights by submitting a Proof of Claim and Release form (“Proof of Claim”) by mail (postmarked no later than January 31, 2025) or electronically via the website (no later than January 31, 2025). Your failure to submit your Proof of Claim by January 31, 2025, will subject your Proof of Claim to rejection and preclude your receiving any of the recovery in connection with the Settlement of this Litigation. If you purchased or otherwise acquired TuSimple securities between April 15, 2021 and December 20, 2022, inclusive, and do not request exclusion from the Settlement Class, you will be bound by the Settlement and any judgment and release entered in the Litigation, including, but not limited to, the Judgment, whether or not you submit a Proof of Claim.
