Registrant determined the incident material — starts the SEC 4-business-day clock
LivaNova PLC filed a supplemental 8-K on December 6, 2023, providing an operational update on a previously disclosed cybersecurity incident (first reported November 20, 2023). The Company reported that U.S. sites are substantially operating at normal levels following a soft launch, and European manufacturing sites have also begun a soft launch.
About this clustering
DisclosureLens links filings into incidents through layered matchers: deterministic rules (same source document, multistate filings of one breach, tight-window same-victim pairs), a weighted-similarity scorer for cross-source candidates, and an operator review queue for everything uncertain. Each link records its own method and confidence — shown per filing in the timeline below. The system defaults to NOT merging when uncertain, because a false merge (collapsing two unrelated breaches) is more harmful than a false split (showing related filings separately); uncertain pairs route to human review instead of auto-merging. Filing summaries shown in the timeline are AI-generated extracts — verify each against its linked source.
