The California Attorney General’s breach-notification listing identifies Plant Construction Company, L.P. and reports that the incident occurred on September 8, 2026. A law firm’s investigation page says the company discovered the incident on October 14, 2026, and began notifying affected individuals on November 13, 2026. The state listing records the filing in November 2026.
The reported data types are names and Social Security numbers. The law firm says more than 500 California residents were affected, but the sources reviewed do not provide an exact entity-level total. They do not confirm exposure of medical or financial data. The available sources identify California but do not establish other affected states or whether the incident involved a third-party vendor.
Further details, including a final affected-person count, may emerge after the initial notice. Consumer notifications may not reach everyone at the same time.
