River Financial amends 8-K, says hacker accessed network and exfiltrated data

River Financial amended its June 19, 2026 Form 8-K cybersecurity disclosure as its investigation progressed.

An unauthorized threat actor accessed parts of the network, removed certain data, and the company is assessing whether personally identifiable information was affected.

No fraud reports have been identified as directly tied to the incident.

Two class action lawsuits were filed following the public disclosure; the company is evaluating the complaints.

The incident’s full scope remains unresolved; the company has not determined whether it is reasonably likely to materially affect results.
