What 8-K filings signal:
Entry into material agreements (new contracts) - Acquisitions and dispositions - Leadership changes (new CEO, CFO, etc.) - Financial events - Press releases on significant developments.
Why salespeople care: 8-K filings appear within days of a major corporate event. A new CFO means budget priorities shift. A new partnership means integration sales opportunities. An acquisition means expanded team and new tooling needs. These are the signals that turn a cold prospect into a warm one.
