NUCOR CORP

Nucor’s management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934, as amended.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management assessed the effectiveness of Nucor’s internal control over financial reporting as of December 31, 2025. In making this assessment, management used criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control – Integrated Framework (2013).

Based on its assessment, management concluded that Nucor’s internal control over financial reporting was effective as of December 31, 2025. PricewaterhouseCoopers LLP, an independent registered public accounting firm, has audited the effectiveness of Nucor’s internal control over financial reporting as of December 31, 2025 as stated in their report which is included herein.
