MAS Acquisition XXIX Corp was a blank check acquisition company — the twenty-ninth vehicle in the numbered MAS Acquisition series — that registered its securities under Section 12(g) of the Securities Exchange Act of 1934. The company operated as an early-generation special purpose acquisition vehicle, a structure that predated the modern SPAC boom, targeting a business combination in the general acquisition sector. On April 18, 2002, the company filed a Form 15-12G with the SEC, formally terminating its Section 12(g) registration obligations, a step typically taken when shareholder-of-record counts fall below regulatory thresholds or a company concludes its public reporting lifecycle. No exchange ticker symbol was assigned to this vehicle.
