New Providence Acquisition Corp. completed its merger with AST & Science LLC on April 6, 2021, acquiring approximately $227 million in trust account proceeds and raising an additional $230 million through private investment, resulting in the renamed AST SpaceMobile, Inc. beginning trading on Nasdaq under ticker ASTS with an up-C corporate structure. The company identified a material weakness in its warrant accounting controls related to improper classification of warrants issued during its September 2019 initial public offering, which required amendment of its prior-year financial statements following SEC guidance issued in April 2021.
