IronNet, Inc., trading under the ticker DFNS on the NYSE American, was the post-combination identity of LGL Systems Acquisition Corp., a blank-check company sponsored by an affiliate of The LGL Group, Inc. that completed its initial public offering in 2020. The SPAC targeted the technology sector with a focus on cybersecurity, ultimately combining with IronNet Cybersecurity, the collective-defense platform founded by former NSA Director General Keith Alexander. The amended annual report on Form 10-K/A filed in May 2021 reflects the company's reporting obligations during its transition period. The combined entity subsequently traded under the ticker IRNT on the NYSE.
