The company reported this breach on September 11, 2026, stemming from an event that occurred on November 6, 2025, confirming that unauthorized parties gained access to its network.

The exposed data categories are highly sensitive. According to the notice, this includes your Full Name, Social Security Number, Date of Birth, Wage and Compensation Information, Tax Return Information, Direct Deposit Account Details, Home Address, Phone Number, and Employment History Records.
