Notice of Security Incident

Kubota is committed to protecting the confidentiality and security of our employees’ information. We identified and addressed an incident involving unauthorized access to certain network systems between March 16, 2026 and April 20, 2026. When we learned of the incident, we immediately took steps to secure our network, and an investigation was conducted to determine what occurred. On April 30, 2026, we discovered that files maintained by our human resources team were accessed as part of this incident. We carefully reviewed these files, and on June 16, 2026, we determined that one or more files may have contained personal information related to certain employees and their dependents.

Given the unique nature of employee records, the information in the files varied by individual. Depending on the employee’s role and benefits elections, the files may have included your name in combination with one or more of the following: Social Security number, date of birth, taxpayer identification number, driver’s license or other government-issued identification number, financial account information for direct deposit, payment card information for corporate cards, and, if enrolled in Kubota’s benefits plan, enrollment and limited claims information. For dependents of employees, the files may have included your name in combination with one or more of the following: Social Security number, date of birth, and, if enrolled in Kubota’s benefits plan, enrollment and limited claims information.

We mailed letters to the affected individuals on June 30, 2026, and arranged for all affected individuals to receive a complimentary membership to identity monitoring services through Kroll. Kubota also established a dedicated, toll-free call center to answer any questions notified individuals may have. The call center may be reached at (844) 959-7144, Monday through Friday from 8:00 a.m. to 5:30 p.m. Central Time, excluding certain U.S. holidays. We take the privacy and confidentiality of our employees’ information very seriously. To help prevent something like this from happening again, we have taken and will continue to take steps to further enhance our existing security measures.
