The Leggett & Platt, Incorporated Employee Benefits Plan formally reported a data security incident to California regulators. This incident, impacting plan participants, was reported on September 15, 2026, though the breach event itself occurred earlier, on October 18, 2025.

According to the public filing, the compromised data elements include Full Name, Social Security Number, Date of Birth, Health Insurance Policy Number, Medical Claim and Treatment Information, Financial Account and Banking Details, Home Address and Contact Information, and Employment and Benefit Status Data.

This combination of data types can lead to complex and long-lasting impacts on individuals' financial and personal security.

Individuals who receive a breach notification are advised to remain vigilant. It is recommended to carefully review financial statements and explanations of benefits for any unauthorized activity. Consider placing a fraud alert or security freeze on credit reports, and promptly report any suspicious activity to relevant financial institutions and credit bureaus. Accessing free credit reports can also help monitor for potential misuse of personal information.

The investigation into this incident is currently ongoing, with authorities monitoring the situation. This information is based on public disclosures made by the Leggett & Platt, Incorporated Employee Benefits Plan to California regulatory bodies, confirming the incident and the categories of data involved.
