On June 18, 2025, the Company sent a letter to CarTech in response to the Termination Notice stating that the Company believes that the termination by Car Tech is invalid due to Car Tech’s previous and continuing breaches of certain key representations, warranties and covenants under the Merger Agreement that materially contributed to the failure of the Mergers to be consummated on or before the Outside Date as provided in Section 10.1(i) of the Merger Agreement. The Company further reserved all rights in full to pursue any an all remedies available to it under the Merger Agreement and at law.
