Hyde Park Acquisition Corp. II is a blank check company formed as a special purpose acquisition company that filed an S-1/A amendment with the SEC on May 16, 2012, under accession number 0001144204-12-030129, placing its IPO in the 2012 vintage. The S-1/A designation indicates the company was refining its registration statement ahead of pricing, a standard step in the SPAC formation process. Organized under the Hyde Park sponsor group, this was the second blank check vehicle launched under that banner. As a 2012-era SPAC, the company has since completed its lifecycle, as virtually all SPACs from that period have resolved through a business combination, extension, or liquidation.
