The bank’s customer base includes residents of Texas, as shown by a 2026 data breach that exposed personal information of approximately two thousand fifty Texas residents.

Happy State Bank’s parent organization is Centennial Bank, as indicated in the 2026 breach notification. The bank has experienced two notable data security incidents. In 2022, an unauthorized party accessed an employee's email account through a phishing attack, compromising the names and Social Security numbers of 10,069 individuals. In 2026, a third‑party vendor inadvertently emailed a customer file to an unintended recipient, potentially exposing names, Social Security numbers, dates of birth, addresses, driver’s license numbers, government identification numbers, financial account information and health insurance data for approximately two thousand fifty Texas residents, with additional individuals possibly affected nationwide. Following each incident, the bank conducted internal investigations, notified affected customers and regulatory authorities, and took remedial actions such as recalling emails, terminating access and destroying the exposed file.
