This law requires M&A-related notification and filing with the Federal Trade Commission. While the focus of the HSR Act is on reviewing the antitrust implications of large M&A deals, it also applies to any acquisition of voting stock over specified yearly thresholds. The law can therefore apply to executives and directors with stock and option grants valued at more than the threshold amount ($111.4 million in 2023).

For details and examples of how the HSR Act applies to stock grants, see discussions from the law firms Cooley and Orrick.
