Pine Island Acquisition Corp. (Nasdaq: PIPP), sponsored by Pine Island Capital Partners, was a blank-check company that completed its initial public offering in January 2021 with a focus on the defense, national security, and government services sectors. The SPAC drew attention for its leadership team of former senior U.S. government and military officials. After failing to consummate a business combination within its allotted window, the company filed a Form 15-12G with the SEC on November 10, 2022, deregistering its securities and formally winding down operations. PIPP's liquidation reflects broader headwinds that pressured defense-focused SPACs during the 2022 market contraction.
