Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to provide reasonable assurance that information required to be disclosed in the reports that Worthington Steel files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including Worthington Steel’s principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

Based on that evaluation, Worthington Steel’s principal executive officer and principal financial officer have concluded that such disclosure controls and procedures designed at the reasonable assurance level and were effective at a reasonable assurance level as of the end of the quarterly period covered by this Form 10-Q.
