(“VIYI”), a Cayman Islands exempted company. On December 9, 2022, the business combination was completed. As a result of the consummation of the business combination, VIYI became a wholly-owned subsidiary of the Company, which has changed its name to MicroAlgo Inc. The business combination was accounted for as a reverse recapitalization in accordance with U.S. GAAP. Under this method of accounting, Venus will be treated as the “acquired” company for financial reporting purposes. This determination was primarily based on the holders of VIYI expecting to have a majority of the voting power of the post-combination company, VIYI senior management comprising substantially all of the senior management of the post-combination company, the relative size of VIYI compared to Venus, and VIYI operations comprising the ongoing operations of the post-combination company. Accordingly, for accounting purposes, the business combination will be treated as the equivalent of VIYI issuing shares for the net assets of Venus, accompanied by a recapitalization.
