How to Read an SEC 8-K Filing (And Why You Should Care)

The takeaway

SEC 8-K filings are public, free, filed within 4 business days of material events, and precede press coverage by hours or days. For public competitors, they're the highest-signal source of strategic intelligence. Learn the item numbers, read them weekly.

What an 8-K is

An 8-K is a filing public companies submit to the SEC when a "material event" happens. The categories are formally defined in the filing, and include:

  • 1.01 / 1.02 / 1.03 — entry into / termination of / bankruptcy under a material agreement
  • 2.01 / 2.05 / 2.06 — acquisitions or impairments
  • 5.02 — departure / appointment of officers or directors
  • 7.01 / 8.01 — Regulation FD disclosures / other events
  • 9.01 — financial statements + exhibits
The number tells you what happened. A 5.02 means a leadership change. A 2.01 means an acquisition.

Why this matters to operators

8-Ks are filed within 4 business days of the event. They typically appear BEFORE the press coverage.

If your competitor is public:

  • A 5.02 reveals their leadership transitions
  • A 2.01 reveals their M&A activity
  • A 1.01 / 1.02 reveals their major partnerships forming or dissolving
  • A 7.01 reveals scheduled communications (earnings, investor decks)

For B2B SaaS operators, public competitor 8-Ks are the highest-signal source of strategic intelligence available.

How to read one

An 8-K has three parts:

  1. Cover page. Item numbers + filing date.
  2. Item descriptions. What happened, written in legal language.
  3. Exhibits. Often a press release, separation agreement, or contract.
Read the item number first to know what kind of event. Read the item description for the official narrative. Then read the exhibit for the press-ready version. The two often differ — the exhibit is what gets quoted; the item description is what's legally required.

Where to find them

SEC EDGAR is the official source. https://www.sec.gov/cgi-bin/browse-edgar lets you search by company, ticker, or filing type. The "current events" view shows all 8-Ks across all filers from the last 24-48 hours.

For tracking specific competitors, set up an email alert via EDGAR or use a tool that monitors filings for you. Morthn Intel surfaces 8-Ks from public competitors in your workspace's industry as part of the weekly brief.

What to do with what you find

8-Ks alone aren't strategic decisions — they're inputs. The discipline is connecting:

  • A CEO transition 8-K + a recent strategy shift = the new CEO is going to change the direction
  • An acquisition 8-K + the acquired company's profile = the competitor is expanding into a new ICP
  • A material agreement 8-K + the counterparty = a new partnership is forming
The filing is the data; the strategic read is the interpretation. That's where the operator earns their edge.

Questions

Are 8-Ks only relevant for public competitors?+

Yes — only publicly-traded companies file them. For private competitors, the analog is Federal Register entries (if regulated) and Crunchbase / PitchBook funding signals.

How long after an event must an 8-K be filed?+

4 business days. Some items have shorter windows. The press coverage typically follows the filing, not the other way around.

Can I get email alerts when a specific company files an 8-K?+

Yes — EDGAR offers free RSS feeds per company. Morthn Intel also includes 8-Ks from public competitors in your workspace's industry in the weekly brief.
