Form 8, officially known as Form 8-K, is a report that publicly traded companies in the United States are required to file with the Securities and Exchange Commission (SEC) to announce major events that shareholders should be aware of. These events can include acquisitions, bankruptcies, resignations of directors, changes in control, or cybersecurity incidents. The timely filing of Form 8-K ensures transparency and keeps investors informed about significant changes that could impact a company’s financial health or operations. For cybersecurity, a breach or significant security incident may trigger the need to file a Form 8-K, alerting stakeholders to potential risks or impacts.
