Item 2.02 Results of Operations and Financial Condition.

On June 24, 2026, Worthington Steel, Inc. (“we,” “us,” “our” and “registrant”) issued a news release (“the Original Financial Release”) reporting results for the three months ended May 31, 2026 (the fourth quarter of fiscal 2026). A copy of the news release was furnished as Exhibit 99.1 to a Current Report on Form 8-K filed by the Company on June 25, 2026. Subsequent to the Original Financial Release, we identified and corrected certain errors in the reported information, as described further below. A copy of the corrected financial release (the “Corrected Financial Release”) is attached hereto as Exhibit 99.1, is incorporated by reference, and supersedes the Original Financial Release in its entirety. Specifically, the Corrected Financial Release reflects additional long-lived asset impairment charges related to certain asset groups within the Electrical Steel reporting unit as well as additional Bridge nonrevolving loan commitment costs.

The additional long-lived asset impairment charges were identified by management during the execution of its standard year-end internal controls procedures over financial reporting for the preparation of our Annual Report on Form 10-K. The additional Bridge nonrevolving loan commitment costs were originally excluded due to an inadvertent error. These errors and the adjustments are isolated to the fourth quarter and full-year fiscal 2026 periods. They do not impact any of our previously filed Quarterly Reports on Forms 10-Q, and do not impact the Company’s previously issued financial guidance, operational outlook or business strategy for the current fiscal year ending May 31, 2027.

Prior to the conference call on June 25, 2026, we made available an investor presentation on our website. This presentation has been updated to reflect the corrected financial information reported in the Corrected Financial Release and is available in the Investors section of our website at www.WorthingtonSteel.com.

The information contained in this Item 2.02, including Exhibit 99.1, is being furnished pursuant to Item 2.02 and shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, unless we specifically state that the information is to be considered “filed” under the Exchange Act or incorporate the information by reference into a filing under the Exchange Act or the Securities Act of 1933, as amended. Information on our website is not incorporated herein.
