Nucor Corporation Under Investigation for Data Breach of Records

Schubert Jonckheer & Kolbe LLP is investigating a data breach impacting the sensitive personal information in the care of Nucor Corporation, a leading producer of steel and steel products headquartered in Charlotte, North Carolina. The company employs over 32,000 people and reported $30.73 billion in revenue last year.

On June 20, 2025, Nucor disclosed the data breach by filing with the U.S. Securities and Exchange Commission. According to the filing, the cyberattack involved unauthorized access to data within the company's IT systems and was detected around May 13, 2025. Following detection of the breach, Nucor launched an investigation with cybersecurity experts. The company reports having discovered that from May 3 to May 13, an unauthorized third party had accessed and acquired certain data, including personal information. Although the breach was detected in early May, 2025, the company had not yet begun notifying individuals whose data may have been impacted by the incident when it filed with the U.S. Securities and Exchange Commission on June 20, 2025. Nucor has not publicly disclosed what information was stolen.

If your personal information was impacted by this incident, you may be at risk of identity theft and other serious violations of your privacy. As a result, you may be entitled to money damages and an injunction requiring changes to Nucor’s cybersecurity practices.
