In connection with the Arrangement Agreement, Vitesse and Lucero effected an arrangement (the "Arrangement") pursuant to, among other provisions, section 193 of the Business Corporations Act (Alberta) (the "ABCA"), and a plan of arrangement (as amended from time to time in accordance with the Arrangement Agreement, the "Plan of Arrangement"). In accordance with the ABCA and the Plan of Arrangement, (i) Vitesse acquired all of the issued and outstanding voting common shares (the "Lucero Shares") of Lucero in exchange for the issuance of Vitesse Common Stock and (ii) each Lucero Share issued and outstanding immediately prior to the effective time of the Arrangement (other than Lucero Shares with respect to which dissenters' rights have been validly exercised and not validly withdrawn) will be transferred by such shareholder to Vitesse in exchange for 0.01239 of a share of Vitesse Common Stock, as may be adjusted pursuant to the Plan of Arrangement. Following the completion of the Arrangement, the number of outstanding shares of Vitesse Common Stock increased by 8,169,368 shares to 38,578,409 outstanding shares of Vitesse Common Stock, and, accordingly, the Reporting Person's percentage beneficial ownership decreased proportionately. The foregoing summary description of the Arrangement does not purport to be complete and is qualified in its entirety by reference to the terms of the Arrangement Agreement, which was filed as Exhibit 2.1 to the Current Report on Form 8-K filed by Vitesse with the Securities and Exchange Commission on December 19, 2024, and is incorporated by reference into this Item 4.
