The 8-K item number is not the event
Every 8-K arrives with item numbers in its header: 2.02 for results, 5.02 for executive changes, 3.01 for listing problems. Most event datasets stop there. The trouble is that one item number can hold events that mean opposite things for a company and its shareholders.
What does a delisting notice actually tell you?
Item 3.01 is filed for a "notice of delisting or failure to satisfy a continued listing rule or standard; transfer of listing". Between January 2022 and August 2026, 8,799 filings carried it, from 2,976 companies. Read a random sample of 1,500 of them and the item splits into very different events:
- Warnings. The exchange says a rule is breached and gives the company time to fix it: the share price below the minimum bid (about 29% of the sample mention it), a late annual or quarterly report (about 29%), equity or assets below the requirement (about 17%).
- Escalations. Exchange staff decide to delist (about 42% mention a delisting determination or suspension), and companies ask for a hearing or appeal (about half).
- Voluntary moves. A company delists because a merger has closed, or simply moves from one exchange to another (about a quarter mention a voluntary delisting or Form 25).
A delisting after a completed merger and a forced delisting share one item number. For anyone measuring how a stock reacts, treating them as one event averages a non-event with a crisis.
And an executive change?
Item 5.02 is broader still: 55,564 filings in the same period, from 7,465 companies. Many are routine: pay arrangements and scheduled board elections. The minority are the ones a reader cares about: about 36% of a 1,500-filing sample mention a resignation, about 15% say "effective immediately", about 11% name an interim replacement. An abrupt chief financial officer exit and an annual bonus approval arrive under the same number.
The point: an event label is only useful if it says which event happened. That means reading the filing itself, and showing the sentence the label rests on, so anyone can check it.
