**Item 8.01 Other Events.**

As previously disclosed, on February 13, 2023, Hyliion Holdings Corp. (the "Company" or "Hyliion") filed a petition (the "Petition") in the Delaware Court of Chancery (the "Court of Chancery") pursuant to Section 205 of the Delaware General Corporation Law. The Petition sought to validate an amendment to the Company's certificate of incorporation increasing the authorized common stock of the Company ("Class A Increase Amendment") and validate the Company's restated certificate of incorporation (the "New Charter"), which gave effect to that amendment and certain other approved amendments, and also reclassified the Company's Class A common stock into "common stock", all in connection with the Company's (then operating under the name Tortoise Acquisition Corp.) business combination with Hyliion Inc. that closed on October 1, 2020.

On March 6, 2023, the Court of Chancery held a hearing on the Petition and issued an order granting the Petition, validating the New Charter and the Class A Increase Amendment as of October 1, 2020, the date the New Charter was initially filed with the Secretary of State of Delaware, and validating all shares of common stock of the Company issued in reliance on the effectiveness of the New Charter and Class A Increase Amendment as of the date of original issuance of any such shares.
