Item 1. Legal Proceedings

In addition to the matter discussed below, refer to Note 14 to our Condensed Consolidated Financial Statements and to our 2025 Annual Report for descriptions of certain legal proceedings.

In March 2026, NL and several other defendants were served with a complaint inCity of Columbus v. NL Industries, Inc., (Franklin County, Ohio Court of Common Pleas, Case No. 26 CV 002355), which was subsequently removed to federal court (United States District Court for the Southern District of Ohio, Case No. 2:26-cv-00465-MHW-SCS). In the complaint, the City of Columbus, Ohio, asserts that NL and several other former lead manufacturers are liable for the cost of replacing lead and galvanized service lines in the City’s water delivery system and related water treatment costs, under theories of public nuisance and civil conspiracy. We intend to deny liability and will defend vigorously against all claims.
