Industrial Services Acquisition Corp. is a blank check company that registered for its initial public offering via an S-1 filing submitted to the SEC on August 22, 2005, making it one of the earlier SPAC vehicles of that decade's first wave. The company targeted the industrial services sector, a broad category encompassing maintenance, repair, environmental remediation, and related outsourced services for industrial operators. Its registration accession number on EDGAR is 0001144204-05-026637. As a 2005-vintage SPAC, the vehicle operated under the structural norms of that era, before the regulatory refinements and disclosure requirements that reshaped the asset class after 2020.
