Build Acquisition Corp. (Nasdaq: BGSX) was a blank-check company that completed its initial public offering in 2021, targeting business combinations in the technology sector. The SPAC operated through the peak and subsequent contraction of the blank-check market cycle before filing a Form 15-12G with the Securities and Exchange Commission on March 27, 2023, formally terminating its class of registered securities under Section 12(g) of the Exchange Act. The deregistration filing marks the close of BGSX's lifecycle as a public reporting entity, an outcome shared by a significant number of 2021-vintage SPACs that did not consummate a transaction within their allotted operating window.
