BOULDER — The Gores Group, a private-equity firm with an office in Boulder, debuted a new special purpose acquisition company, or SPAC, and raised $300 million in the process. The company, Gores Holdings VI Inc. (Nasdaq: GHVIU), launched on the markets on Friday and is trading 50 to 60 cents above its initial public offering price of $10 per share. The company has not had any material discussions with an acquirer looking to go public, according to filings with the U.S. Securities and Exchange Commission. SPACs are shell companies that are listed on public exchanges and are later acquired by companies looking to go public outside of the normal procedures of an initial public offering. They do not require the private company to release an S-1 filing to the U.S. Securities and Exchange Commission with financial data.
