When must a company file an 8-K? The SEC requires
Post# of 85504
The SEC requires companies to file an 8-K to announce significant events relevant to shareholders. Companies have four business days to file an 8-K for most specified items. Public companies use Form 8-K as needed, unlike some other forms that must be filed annually or quarterly.
This is what is most important and why we can see an 8k any day.
