FreeWire Technologies Inc., an electric-vehicle charging and power startup, is in talks to go public through a merger with DHC Acquisition Corp. (NasdaqCM:DHCA), a blank-check firm, according to people with knowledge of the matter. DHC is discussing raising new equity to support a transaction, which is slated to value the combined entity at more than $1 billion, one of the people said. As with all deals that aren’t finalized, terms could change and it’s possible talks could fall apart. Representatives for FreeWire and DHC didn’t immediately have a comment.
