Novelis, Inc. (SEC 10-K Item 1C) discloses no actual cybersecurity incidents occurred during the reporting period. The filing details the company's cybersecurity risk management, governance structure (CIO/CISO oversight), and third-party vendor risk policies. It explicitly states: 'we have not experienced a data breach or system disruption... that has had a material effect on our operations.' The document serves as a risk disclosure, not a breach notification.
