QMCO is not the only one.
See every restatement we've found across the market — or get an alert the next time QMCO revises a number.
Restatements are detected by comparing every vintage of a fact across all of QUANTUM CORP /DE/'s filings back to 1993. A revision is not by itself a sign of wrongdoing — companies re-file for many legitimate reasons. This list is not exhaustive: it shows QMCO's most significant revisions, and a figure absent from it has not been certified as unrevised.
