Clover Health Investments, Corp.

Item 8.01. Other Events. On July 4, 2026, Clover Health Investments, Corp. (the “Company”) became aware of anomalous login activity on certain of its information systems. The Company immediately activated its incident response procedures, initiated an investigation with assistance from leading third-party cybersecurity experts, and took steps to contain the activity. The Company also notified law enforcement. The investigation subsequently showed that a threat actor gained access to three non-managerial health plan employee accounts through social engineering. Based on preliminary findings from the Company’s investigation, those accounts were assigned to employees who had member visit-scheduling and broker-facing sales functions. The employee accounts had access to certain personally identifiable information and protected health information, but had no access to corporate financial or claims systems. While the investigation is ongoing into the precise nature, scope, and extent of data that was subject to unauthorized access and acquisition, the Company believes that its rapid response successfully contained and terminated the unauthorized access. Based on information available as of the date of this filing, the Company does not believe that the incident has had, or is reasonably likely to have, a material impact on its business, financial condition or results of operations. The Company takes the privacy and security of its member data very seriously and has taken, and continues to take, steps to further harden its IT environment. The Company continues to evaluate applicable regulatory and legal notification requirements and will make all required notifications based on its findings, including to impacted members.
