About this score

reportingrisk.com scores every active US filer on three things a company tells the SEC about itself: late-filing notices on Form NT, 8-K item 4.02 (past accounts declared unreliable) and 4.01 (auditor changes). 1,012 are flagged today.

Every score is frozen and checked twelve months later. Across 91,452 of them, a company scoring 4 or more ended that year delisted, bankrupt, restated or silent 17.2% of the time, against 4.0% for a clean record. Scores before 2026-09-27 were reconstructed from the filing history as it stood at each date, so the record is a backtest rather than years of live calls.
