Millstream II Acquisition Corp filed its S-1 registration statement with the Securities and Exchange Commission on October 25, 2004, positioning it among the early generation of blank-check vehicles that helped define the modern SPAC structure. The "II" designation indicates the management team had previously sponsored a predecessor Millstream acquisition entity, reflecting the multi-vehicle sponsor model common among early SPAC practitioners. Filed under SEC CIK 0001304562, the company operated as a general-purpose acquisition vehicle without a publicly disclosed sector mandate, consistent with the broad-target approach typical of 2004-era SPACs.
