BOISE CASCADE Co

Evaluation of Disclosure Controls and Procedures

We maintain "disclosure controls and procedures," as defined in Rule 13a-15(e) under the Exchange Act. We have designed these controls and procedures to reasonably assure that information required to be disclosed in our reports filed or submitted under the Exchange Act, such as this Form 10-Q, is recorded, processed, summarized, and reported within the time periods specified in the Securities and Exchange Commission's rules and forms. We have also designed our disclosure controls to provide reasonable assurance that such information is accumulated and communicated to our senior management, including our chief executive officer (CEO) and our chief financial officer (CFO), as appropriate, to allow them to make timely decisions regarding our required disclosures. Based on their evaluation, our CEO and CFO have concluded that as of March 31, 2025, our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the three months ended March 31, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
