Repeat Item 1.05 filers

20 companies have filed more than one Form 8-K or 8-K/A that SEC EDGAR’s own full-text search codes under Item 1.05, Material Cybersecurity Incidents, since the item took effect on December 18, 2023. A record of who disclosed more than once — this page draws no conclusion about why, since a second filing can be an amendment to the first, a wholly separate incident, or an update as an investigation continues. See the full Item 1.05 filings tracker for every filing, including single-time filers.
