Coastal Bancshares Acquisition Corp. (CBAS) was a blank-check company formed during the mid-2000s SPAC wave, targeting acquisitions in the financial services and community banking industry. On March 15, 2007, the company filed a Form 15-12G with the Securities and Exchange Commission, formally suspending its Section 12(g) registration and closing out its public reporting obligations — a filing that marks the conclusion of a SPAC's public lifecycle, generally following a completed business combination or an operational wind-down. The company's IPO is consistent with the 2005–2006 vintage of that era's blank-check issuance surge. Sponsor details were not identified in the available filing record.
