Item 7.01 Regulation FD Disclosure.*

On July 15, 2026, Worthington Steel, Inc., an Ohio corporation (the “Company” or “Worthington Steel”) issued a press release announcing the opening of the acceptance period for the public delisting tender offer (“Delisting Offer”) for all outstanding shares of Klöckner & Co SE, a European stock corporation (societas europaea) organized under the laws of Germany (“Kloeckner”) not already held by Worthington Steel, by Worthington Steel GmbH, a limited liability company established under German law (Gesellschaft mit beschränkter Haftung) (“Bidder”) and a wholly owned indirect subsidiary of Worthington Steel, following approval of the offer document for the Delisting Offer (the “Delisting Offer Document”) by the German Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicht – “Bafin”) and publication in accordance with the German Securities Acquisition and Takeover Act (Wertpapiererwerbs- und Übernahmegesetz – “WpÜG”). A copy of the press release is furnished herewith as Exhibit 99.1 and is incorporated herein by this reference.

* The information “furnished” in this Current Report on Form 8-K under Item 7.01 (including Exhibit 99.1) shall not be deemed to be “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any registration statement or other filing under the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such filing.

Important Information

This Current Report on Form 8-K and the materials included herewith constitute neither an offer to purchase nor a solicitation of an offer to sell Kloeckner shares. The terms relating to the Delisting Offer are set out in the offer document which has been published following authorization by Bafin. Bidder reserves the right to deviate from the key points set out herein and in the Delisting Offer Document in the final terms of the Delisting Offer to the extent legally permissible. Investors and Kloeckner shareholders are strongly advised to read the offer document and all other documents relating to the Delisting Offer, as they contain important information.

The Delisting Offer is made exclusively on the basis of the applicable provisions of German law, in particular the German Securities Acquisition and Takeover Act (Wertpapiererwerbs- und Übernahmegesetz – “WpÜG”) and certain securities laws provisions of the United States of America (the “United States” or “U.S.”). The Delisting Offer is not made in accordance with the legal requirements of any jurisdiction other than the Federal Republic of Germany or the United States (to the extent applicable). Accordingly, no announcements, registrations, approvals or authorizations for the offer have been made, arranged for or granted outside the Federal Republic of Germany or the United States (to the extent applicable). Investors and holders of Kloeckner shares may not claim to be protected by the investor protection laws of any jurisdiction other than the Federal Republic of Germany or the United States (as applicable). Subject to the exceptions described in the offer document and any exemptions to be granted by the relevant regulatory authorities, no Delisting Offer is being made, directly or indirectly, in any jurisdiction where to do so would constitute a violation of applicable national law. This Current Report on Form 8-K may not be published or otherwise distributed, in whole or in part, in any jurisdiction in which the Delisting Offer would be prohibited by applicable national law.

Bidder and its affiliates or affiliates of its financial advisor reserve the right to directly or indirectly purchase or arrange to purchase Kloeckner shares or any other securities that are convertible into, exchangeable for or exercisable for such Kloeckner shares outside of the Delisting Offer, provided that such purchases or arrangements to purchase are not made in the United States and comply with the applicable German statutory provisions, in particular the WpÜG. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Information about such purchases or arrangements to purchase, including the number of Kloeckner shares purchased or to be purchased and the consideration paid or agreed, will be published in German and English language without undue delay if and to the extent required under the laws of the Federal Republic of Germany, the United States or any other relevant jurisdiction.

The Delisting Offer referenced in this Current Report on Form 8-K relates to shares in a German company and is subject to the statutory provisions of the Federal Republic of Germany on the implementation of such an offer, which differ from those of the United States and other jurisdictions in certain material respects. The financial information relating to Bidder and Kloeckner included elsewhere, including in the Delisting Offer Document, are prepared in accordance with provisions applicable in the Federal Republic of Germany and are not prepared in accordance with generally accepted accounting principles in the United States; therefore, it may not be comparable to financial information relating to U.S. companies or companies from other jurisdictions outside the Federal Republic of Germany. The Delisting Offer has not been submitted to the review or registration procedures of any securities regulator

outside of Germany and has not been approved or recommended by any other securities regulator. Kloeckner shareholders whose place of residence, incorporation or place of habitual abode is in the United States should note that the Delisting Offer is made in respect of securities of a company which is a foreign private issuer within the meaning of the U.S. Securities Exchange Act of 1934, as amended (the “U.S. Exchange Act”), and the shares of which are not registered under Section 12 of the U.S. Exchange Act and that the company is not subject to the periodic reporting requirements of the U.S. Exchange Act, and is not required to, and does not, file any reports with the U.S. Securities and Exchange Commission (the “SEC”) thereunder. The Delisting Offer is made in the United States pursuant to Section 14(e) and Regulation 14E under the Exchange Act, subject to the exemption provided under Rule 14d-1(d) under the U.S. Exchange Act, for a Tier II tender offer and is principally governed by disclosure and other regulations and procedures of the Federal Republic of Germany, including with respect to the Delisting Offer timetable, settlement procedures, withdrawal and timing of payments, which are different from those of the United States. The Delisting Offer is made to Kloeckner’s shareholders resident in the United States on the same terms as those made to all other shareholders of Kloeckner to whom an offer is made. Any informational documents, including this Current Report on Form 8-K, will be disseminated to U.S. shareholders on a basis comparable to the method that such documents are provided to Kloeckner’s other shareholders. To the extent that the Delisting Offer is subject to U.S. securities laws, such laws only apply to Kloeckner shareholders in the United States, and no other person has any claims under such laws.

Any agreement concluded with the bidder as a result of the acceptance of the Delisting Offer will be governed exclusively by the laws of the Federal Republic of Germany and shall be construed accordingly. It may be difficult for Kloeckner shareholders from the United States (or from jurisdictions other than Germany) to enforce their rights and claims arising in connection with the Delisting Offer under the Securities Act of 1933 (or other laws known to them) because the bidder and Kloeckner are located outside the United States (or the jurisdiction in which the shareholder is domiciled) and their respective officers and directors are domiciled outside the United States (or the jurisdiction in which the shareholder is domiciled). It may be impossible to sue a non-U.S. company or its officers and directors in a non-U.S. court for violations of U.S. securities laws. It may also be impossible to compel a non-U.S. company or its subsidiaries to submit to the judgment of a U.S. court.

Forward-Looking Statements

This Current Report on Form 8-K includes forward-looking statements, including forward-looking statements within the meaning of the U.S. Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act of 1933 and Section 21E of the U.S. Exchange Act.

These risks and uncertainties include, but are not limited to, (i) the ability of the parties to successfully complete the proposed acquisition on the anticipated terms and timing, (ii) the effects of the transaction on Worthington Steel’s and Kloeckner’s operations, including on the combined company’s future financial condition and performance, operating results, strategy and plans, including anticipated tax treatment, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, losses, future prospects, and business and management strategies for the management, expansion and growth of the new combined company’s operations, and (iii) the other factors detailed in Worthington Steel’s reports filed with the SEC, including its most recent Annual Report on Form 10-K and subsequent Quarterly Reports on Form 10-Q under the caption “Risk Factors,” as well as the other risks discussed in Worthington Steel’s filings with the SEC. In addition, these statements are based on assumptions that are subject to change. Further, it cannot be ruled out that Worthington Steel and/or Kloeckner will change their intentions and assessments expressed in documents or notifications or in Delisting Offer Document or other documents or notifications relating to the Delisting Offer.
