The distribution
| Item Code | What it is | Count | % of week |
|---|---|---|---|
| 8.01 | Other Events (catch-all) | 340 | 23.8% |
| 7.01 | Regulation FD Disclosure | 326 | 22.8% |
| 2.02 | Earnings Results | 290 | 20.3% |
| 5.02 | Officer / Director Departure or Appointment | 206 | 14.4% |
| 1.01 | Material Definitive Agreement Entered | 195 | 13.6% |
| 3.01 | Delisting / Listing Rule Failure | 36 | 2.5% |
| 1.02 | Material Agreement Terminated | 17 | 1.2% |
| 2.01 | Acquisition / Disposition Completed | 13 | 0.9% |
| 1.03 | Bankruptcy or Receivership | 4 | 0.3% |
| 2.06 | Material Impairment | 1 | 0.07% |
Pattern 1 — earnings season is alive
Item 2.02 (Earnings Results) at 290 filings = 20.3% of the week is exactly what you'd expect during the post-Q1-earnings window (April 15-30). Companies with December fiscal-year-ends file their Q1 results 30-45 days after quarter close; the week of April 16-22 catches the bulge.
Implication for /events/type/earnings/ users: this is the time to read the commentary section of each release, not just the headline number. Surprise directionality in earnings 8-Ks correlates with stock reaction more reliably during high-volume weeks like this one.
Pattern 2 — the 8.01 + 7.01 'general communications' bulge
Item 8.01 (Other Events, 340) and Item 7.01 (Regulation FD Disclosure, 326) together account for 46.6% of the week's 8-Ks. These are the catch-all categories — companies use them when an event is material but doesn't fit a more-specific item.
Investment-grade signal value: low to medium. Item 8.01 in particular is often used for press releases that don't cleanly map to a numbered item. Item 7.01 is more meaningful — Reg FD disclosures are typically announcements of investor presentations or analyst calls, often containing forward guidance not yet in earnings releases.
Pattern 3 — officer changes (5.02) at 206
14.4% of the week's 8-Ks were Item 5.02 (Officer / Director Departure or Appointment). That's a meaningful number — typically 5.02 spikes during proxy season (Q1-Q2) as boards reshuffle and new directors are seated. Each 5.02 event has signed EventScore implications: a CEO departure is generally negative, an unexpected CEO appointment more uncertain, a director addition more neutral.
Per-event interpretation requires reading the actual filing's narrative section. See /events/type/officer-change/ for the full week's per-officer breakdown.
Pattern 4 — distress signals (1.03 + 3.01) low
Only 4 bankruptcy filings (Item 1.03) and 36 delisting notices (Item 3.01) for the week. As a rough macro indicator, this is a healthy week — distress filings tend to cluster during recessionary periods (2008-2009 weeks routinely saw 15-25 bankruptcies; 2020 Covid weeks similar).
The 1 material impairment (Item 2.06) is also notably low. A high-frequency impairment week often precedes a goodwill-write-down wave that drags Q-earnings for the following quarter.
Pattern 5 — cybersecurity disclosure absence
Zero Item 1.05 (Material Cybersecurity Incident) filings for the week. Item 1.05 was added to the 8-K taxonomy by the SEC in December 2023 with a 4-business-day filing requirement after determination of materiality. Industry-wide compliance has been below initial estimates; a zero-filing week is consistent with that pattern.
Watch /events/type/cybersecurity/ for the running tally; cybersecurity 8-Ks remain a high-EventScore-magnitude category when they do fire (typical EventScore = -60).
