Stocktitan • July 18, 2026

Clover Health Investments, Corp. reports a cybersecurity incident involving anomalous login activity detected on July 4, 2026 on certain information systems. An investigation, supported by third-party cybersecurity experts, determined that a threat actor accessed three non-managerial health plan employee accounts through social engineering.

The affected accounts were used for member visit-scheduling and broker-facing sales functions and had access to some personally identifiable information and protected health information, but no access to corporate financial or claims systems. Clover Health states that its rapid response contained and terminated the unauthorized access and, based on information currently available, it does not believe the incident has had, or is reasonably likely to have, a material impact on its business, financial condition, or results of operations. The company has notified law enforcement, is further hardening its IT environment, and will provide required notifications, including to impacted members, once its assessment of the scope and nature of any data access is complete.
