THIS NOTICE WAS AUTHORIZED BY THE COURT. IT IS NOT JUNK MAIL, AN ADVERTISEMENT, OR SOLICITATION FROM A LAWYER.

PLEASE READ THIS NOTICE CAREFULLY AND IN ITS ENTIRETY. YOUR RIGHTS MAY BE AFFECTED BY PROCEEDINGS IN THE LITIGATION. PLEASE NOTE THAT IF YOU ARE A SETTLEMENT CLASS MEMBER, YOU MAY BE ENTITLED TO SHARE IN THE PROCEEDS OF THE SETTLEMENT DESCRIBED IN THIS NOTICE. TO CLAIM YOUR SHARE OF THE SETTLEMENT PROCEEDS, YOU MUST SUBMIT A VALID PROOF OF CLAIM AND RELEASE FORM (“PROOF OF CLAIM”) POSTMARKED OR SUBMITTED ONLINE ON OR BEFORE NOVEMBER 11, 2024.

YOU ARE HEREBY NOTIFIED that a hearing will be held on November 19, 2024, at 3:00 p.m. MST, before the Honorable Regina M. Rodriguez, U.S. District Court for the District of Colorado, Alfred A. Arraj United States Courthouse, 901 19th Street, Denver, CO 80294, to determine whether: (1) the proposed settlement (the “Settlement”) of the action pending in the United States District Court for the District of Colorado styled as Shafer v. Lightning eMotors, Inc., et al., No. 1:21-cv-02774-RMR-KAS (the “Federal Action”), as well as the action pending in the Delaware Court of Chancery styled as Delman v. GigAcquisitions3, LLC, et al., C.A. No. 2021-0679-LWW (the “State Action,” and together with the Federal Action, the “Actions”) as set forth in the Stipulation of Settlement dated July 1, 2024 (“Stipulation”)¹ for $13,350,000 in cash should be approved by the Court as fair, reasonable, and adequate; (2) the Judgment as provided under the Stipulation should be entered with prejudice; (3) to award Plaintiffs’ Counsel attorneys’ fees and expenses out of the Settlement Fund (as defined in the Notice of: (I) Proposed Settlement and Plan of Allocation; (II) Settlement Hearing; and (III) Motion for an Award of Attorneys’ Fees and Expenses (“Notice”), which is discussed below), and, if so, in what amount; (4) to award Plaintiffs for representing the Settlement Class out of the Settlement Fund and, if so, in what amount; and (5) the Plan of Allocation should be approved by the Court as fair, reasonable, and adequate.

This Summary Notice relates to a proposed settlement of claims in two pending class actions brought by investors in GigCapital3, Inc. and/or Lightning eMotors, Inc. securities. The Federal Action alleges that Defendants violated the federal securities laws by engaging in a fraudulent scheme, including by making false and misleading statements and omissions regarding, among other things, Lightning eMotors’ growth and revenue projections, supply chain capabilities, and ability to scale during the Class Period. The Federal Action alleges that Defendants’ misrepresentations and omissions artificially inflated the prices of Lightning Securities during the Class Period, resulting in damage to Settlement Class Members when the truth was revealed. The State Action alleges that certain Defendants violated Delaware state law by impairing GigCapital3 shareholders’ redemption rights, including through proxy solicitation materials containing false and misleading misrepresentations and omissions, resulting in damage to Settlement Class Members. Defendants deny each and every claim and contention alleged in the Actions and deny any misconduct or wrongdoing whatsoever.

IF YOU PURCHASED OR OTHERWISE ACQUIRED GIGCAPITAL3 OR LIGHTNING EMOTORS SECURITIES FROM MAY 18, 2020 THROUGH AND INCLUDING AUGUST 16, 2021, YOUR RIGHTS MAY BE AFFECTED BY THE SETTLEMENT OF THE FEDERAL ACTION AND THE STATE ACTION.

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 November 11, 2024) or electronically (no later than November 11, 2024). Your failure to submit your Proof of Claim by November 11, 2024, will subject your claim to rejection and preclude your receiving any of the recovery in connection with the Settlement of the Federal Action and the State Action. If you are a member of the Settlement Class and do not request exclusion therefrom as instructed, you will be bound by the Settlement and any judgment and release entered in the Federal Action and the State Action, including, but not limited to, the Judgment, whether or not you submit a Proof of Claim.

If you have not received a copy of the Notice, which more completely describes the Settlement and your rights thereunder (including your right to object to the Settlement), and a Proof of Claim, you may obtain these documents, as well as a copy of the Stipulation (which, among other things, contains definitions for the defined terms used in this Summary Notice) and other settlement documents, online at www.LightningeMotorsSecuritiesSettlement.com, or by writing to:
