MAS Acquisition XLIII Corp was a blank-check acquisition vehicle — part of an extensively numbered series of shell entities bearing the MAS Acquisition name — that operated during the early SPAC era of the late 1990s and early 2000s. The company, registered under SEC CIK 0001103048, filed a Form 15-12G with the Securities and Exchange Commission on April 18, 2002, formally terminating its registration under Section 12(g) of the Securities Exchange Act of 1934 and signaling the wind-down of the vehicle without a completed business combination. As a pre-modern SPAC predecessor, MAS Acquisition XLIII Corp targeted acquisition opportunities in an era before standardized SPAC structures became common on major exchanges.
