M III Acquisition Corp., sponsored by M III Partners and trading under the ticker IEA following its 2018 business combination with Infrastructure and Energy Alternatives, filed a Form 15-12G with the SEC on November 1, 2022, initiating the termination of its registration under Section 12(g) of the Securities Exchange Act. The SPAC, which held its initial public offering in 2015, completed its de-SPAC transaction in the infrastructure and renewable energy construction services sector. The 15-12G filing marked the conclusion of IEA's public reporting obligations following MYR Group's acquisition of the company earlier in 2022, effectively closing the book on the SPAC life cycle.
