Primary document for annual risk and business changes
Step 2
10-Q: quarterly update
The 10-Q updates financial statements and MD&A during the year. It is usually shorter than a 10-K and helps track whether trends are improving, worsening, or changing direction.
Best for recent revenue, margin, liquidity, and cash flow movement
Compare against the latest 10-K baseline
Watch changed risk language and management explanations
Step 3
8-K: material event report
The 8-K reports important events between periodic filings. It can cover earnings releases, leadership changes, acquisitions, financings, delistings, auditor changes, or other material updates.
Best for fresh event monitoring
Item numbers explain the event category
Exhibits often contain the real substance
