News about BEN & DHCA

Important Company Update BEN Announces Transaction with DHC Acquisition Corp. A SPAC is a company that is formed for the purposes of engaging in a business combination transaction with another company, with the result being, among other things, that the combined company is publicly traded. Because DHC is already publicly-traded, BEN will become a publicly-traded company when the transaction is complete, trading on Nasdaq under the new ticker symbol “BNAI.” The transaction is expected to close as early as in the first quarter of 2024. The combination with DHC is expected to provide access to additional financing resources. Copyright Brand Engagement Network, Inc. 2023 All Rights Reserved (Confidential)
