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). The Original Financial Release included a non-GAAP reconciliation table for EBIT, Adjusted EBIT and Adjusted EBITDA for the three months ended May 31, 2026 and 2025 in which footnote (2) to the table was erroneously duplicated from footnote (1). A corrected version of the news release (the "Financial Release") is furnished herewith as Exhibit 99.1 and is incorporated herein by reference, in which footnote (2) to the non-GAAP reconciliation table for EBIT, Adjusted EBIT and Adjusted EBITDA for the three months ended May 31, 2026 and 2025 has been corrected to read: "Excludes the noncontrolling interest portion of restructuring and other (income) expense, net of $0.7 million in the fiscal 2025 period." No other changes have been made to the Original Financial Release.

We will host a conference call at 8:30 a.m. ET on June 25, 2026, to discuss our unaudited financial results for the fourth quarter of fiscal 2026 and address our outlook for the first quarter of fiscal 2027. The conference call is accessible through Events & Presentations in the Investors section of our website at www.WorthingtonSteel.com, or by registering online at https://events.q4inc.com/attendee/699991251 for the live conference. Prior to the conference call, we made available an investor presentation on our website. The investor presentation is furnished herewith as Exhibit 99.2 and is incorporated herein by reference.

Financial measures prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) and non-GAAP financial measures are included in the Financial Release and the investor presentation, and will be discussed during the conference call, to provide investors with additional information that we believe allows for increased comparability of the performance of our ongoing operations from period to period. Please see the Financial Release and the investor presentation for further explanations of why we use the non-GAAP financial measures and the reconciliations to the most directly comparable GAAP financial measures.

The information contained in this Item 2.02, including Exhibit 99.1 and Exhibit 99.2, 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.
