#### Explanatory Note
On January 15, 2026, Worthington Steel, Inc. (the "<u>Company</u>"), Worthington Steel GmbH ("<u>BidCo</u>"), and Klöckner & Co SE ("<u>Klöckner</u>") entered into a business combination agreement (the "<u>BCA</u>") governing the key terms and conditions based on which BidCo launched a voluntary public cash takeover offer to all shareholders of Klöckner to tender each issued and outstanding share of Klöckner (the "<u>Klöckner Shares</u>") to BidCo at a cash consideration of €11.00 per Klöckner Share (such offer, as amended, the "<u>Offer</u>," and the transactions contemplated thereby, the "<u>Klöckner Acquisition</u>"). On June 3, 2026 (the "<u>Settlement Date</u>"), the Company completed the Klöckner Acquisition, including the settlement of the Offer and BidCo's acceptance and payment for all Klöckner Shares tendered prior to or on April 14, 2026.

| **Item 2.01** | **Completion of Acquisition or Disposition of Assets.**  |

---

The information set forth above in the Explanatory Note of this Current Report on Form 8-K is incorporated by reference into this Item 2.01.

As of April 14, 2026, 52,389,508 Klöckner Shares had been tendered for acceptance under the Offer and not withdrawn (the "<u>Tendered Shares</u>"). On the Settlement Date, BidCo accepted the transfer of Tendered Shares for consideration of €11.00 per Tendered Share. Together with the Klöckner Shares already held by the Company and its affiliates prior to the Settlement Date, the Company now holds a total of 60,710,791 Klöckner Shares, representing approximately 60.86% of Klöckner's total outstanding share capital. The total aggregate consideration for the Tendered Shares was €576,284,588. The Company used the net proceeds from its previously announced notes offering denominated in U.S. Dollars and Euros and borrowing under its term loan, together with cash on hand, to fund the Klöckner Acquisition and pay related fees and expenses.

The foregoing description of the Offer and the BCA, and the transactions contemplated thereby, is only a summary and does not purport to be complete and is qualified in its entirety by reference to the full text of the BCA, a copy of which was filed as Exhibit 2.1 to the Company's Current Report on Form 8-K filed with the SEC on January 15, 2026.

#### Operations of Klöckner During the Transition Period
Prior to the execution (the "<u>Transition Period</u>") of a Domination and Profit and Loss Transfer Agreement (the "<u>DPLTA</u>") (as described below), the Company and BidCo, on the one hand, and Klöckner, on the other hand, will continue to operate as independent companies. During the Transition Period, the relationship between the Company and Klöckner will be qualified as a de-facto group within the meaning of Sections 311 et seq. of the German Stock Corporation Act (the "<u>AktG</u>") and Klöckner's management board will remain independent and will not be subject to binding instructions from the Company or its subsidiaries. In accordance with German law, during the Transition Period, any measures induced by the Company that result in a disadvantage to Klöckner within the meaning of Section 311 of the AktG must be compensated by the Company.

The Company intends to negotiate a cooperation agreement and services agreement with Klöckner that together will establish a framework for governing the relationship between the parties during the Transition Period, including cooperation with respect to strategic direction, operations and governance of Klöckner, and the provision of certain sourcing, materials, operational and commercial services between the parties on arm's length, market-competitive terms, in each case subject to applicable law.

#### Operations of Klöckner Following Execution of a Domination and Profit and Loss Transfer Agreement
The Company intends to cause the Company (or one of its subsidiaries) and Klöckner to enter into the DPLTA under Sections 291 et seq. of the AktG. The DPLTA would provide the Company with the right to issue binding instructions to the management board of Klöckner with respect to the management of Klöckner's business and would obligate Klöckner to transfer its annual profits to the Company. In return, the Company would be required, under the terms of the DPLTA, to (i) compensate Klöckner for any annual losses, (ii) compensate the remaining minority shareholders of Klöckner through a guaranteed annual recurring compensation and (iii) offer to acquire the remaining Klöckner Shares held by such minority shareholders in exchange for fair exit cash compensation, in each case as determined in accordance with applicable German law. The remaining minority shareholders of Klöckner may challenge the adequacy of the recurring compensation or exit compensation through court appraisal proceedings, which could result in court-ordered increases to such amounts.

The execution and effectiveness of the DPLTA is subject to a number of conditions and procedural requirements under German law, including:

• approval by the supervisory board of Klöckner;

------

• approval by the general shareholders' meeting of Klöckner by a vote of at least 75% of the share capital represented at such meeting;

• a valuation of Klöckner by a court-appointed independent auditor to determine the adequate amount of the recurring compensation and the exit compensation to be offered to minority shareholders; and

• registration of the DPLTA with the commercial register of the competent local German court.

There can be no assurance that the DPLTA will be executed or become effective, or as to the timing thereof.

\* 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 is for informational purposes only and does not constitute an offer to sell or the solicitation of an offer to buy any securities in any jurisdiction. The Offer was made exclusively on the basis of the applicable provisions of German law, in particular the German Securities Acquisition and Takeover Act ("WpÜG") and certain securities laws provisions of the United States of America (the "United States" or "U.S."). The Offer was 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). No announcements, registrations, approvals or authorizations for the Offer were made, arranged for or granted outside the Federal Republic of Germany or the United States (to the extent applicable). Subject to the exceptions described in the offer document, as amended, and any exemptions granted by the relevant regulatory authorities, the Offer was not made, directly or indirectly, in any jurisdiction where to do so would have constituted a violation of applicable national law.

The Offer related to shares in a German company and was 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 BidCo and Klöckner included elsewhere, including in the offer document, as amended, was

------

prepared in accordance with provisions applicable in the Federal Republic of Germany and was 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 Offer was not submitted to the review or registration procedures of any securities regulator outside of Germany and was not approved or recommended by any other securities regulator. Klöckner shareholders whose place of residence, incorporation or place of habitual abode is in the United States should note that the Offer was 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 Klöckner 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 Offer was made in the United States pursuant to Section 14(e) and Regulation 14E under the U.S. 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 was principally governed by disclosure and other regulations and procedures of the Federal Republic of Germany, including with respect to the takeover offer timetable, settlement procedures, withdrawal, waiver of conditions and timing of payments, which are different from those of the United States. The Offer was made to Klöckner's shareholders resident in the United States on the same terms and conditions as those made to all other shareholders of Klöckner to whom the Offer was made. To the extent that the Offer was subject to U.S. securities laws, such laws applied only to Klöckner shareholders in the United States, and no other person has any claims under such laws.

BidCo and its affiliates or affiliates of its financial advisor reserved the right to directly or indirectly purchase or arrange to purchase Klöckner shares or any other securities that are convertible into, exchangeable for or exercisable for such Klöckner shares outside of the Offer, provided that such purchases or arrangements to purchase were not made in the United States and complied with the applicable German statutory provisions, in particular the WpÜG. Information about such purchases or arrangements to purchase, including the number of Klöckner shares purchased and the consideration paid, was published in German and English language without undue delay to the extent required under the laws of the Federal Republic of Germany, the United States or any other relevant jurisdiction.

Any agreement concluded with BidCo as a result of the acceptance of the Offer is governed exclusively by the laws of the Federal Republic of Germany and shall be construed accordingly. It may be difficult for shareholders from the United States (or from jurisdictions other than Germany) to enforce their rights and claims arising in connection with the Offer under the U.S. Securities Act of 1933, as amended (or other laws known to them) because BidCo and Klöckner 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.

## Exhibit 99.1

**Exhibit 99.1**![LOGO](g31520g04d06.jpg)

**Worthington Steel Completes Acquisition of Kloeckner & Co and Announces Intention to Launch Delisting Tender Offer** 

**COLUMBUS, OHIO (June 3, 2026) –** Worthington Steel, Inc. (NYSE: WS) today completed its voluntary public takeover offer (the "Takeover Offer") for Kloeckner & Co SE ("Kloeckner"), a leading global service center and metal processing company, following satisfaction of all closing conditions. Worthington Steel has currently secured approximately 62% of Kloeckner's outstanding shares.

Completion of the Takeover Offer establishes the foundation for a strong strategic partnership between Worthington Steel and Kloeckner. Worthington Steel expects the transaction to broaden its product portfolio, diversify end-market exposure and strengthen its geographic footprint. Over time, the combined company anticipates it will benefit from increased scale, operational efficiencies and the sharing of best practices across both organizations.

"This is an important milestone for Worthington Steel and a meaningful step forward in our growth strategy," said Geoff Gilmore, Worthington Steel President and CEO. "Kloeckner brings strong capabilities, a talented team and a shared commitment to performance. We are excited about what we can build together over time and will continue to take a disciplined approach as we move toward integration - stronger together."

"With the completion of this transaction, a new chapter begins for Kloeckner," said Guido Kerkhoff, CEO of Kloeckner & Co SE. "This is the outcome of a deliberate strategic journey: focusing our business on higher-value products and services, building scale in North America and Europe, and finding in Worthington Steel a partner that shares our vision. Our employees, customers and commercial partners can count on continuity and can rely on a stronger platform for long-term growth."

**Worthington Steel pursues Delisting of Kloeckner** 

Worthington Steel intends to launch a Public Delisting Tender Offer ("Delisting Offer") for all outstanding Kloeckner shares (ISIN: DE000KC01000) not already held by Worthington Steel. The company expects to offer remaining Kloeckner shareholders EUR 11.00 in cash per Kloeckner share.

The delisting is expected to reduce administrative and regulatory obligations associated with maintaining Kloeckner's stock exchange listing, while providing greater flexibility to support the long-term strategic development of the business.

Following the effectiveness of the delisting, Kloeckner shares will no longer be admitted to trading on a regulated market in Germany or on a comparable market abroad, which may result in significantly reduced liquidity and limited price discovery for Kloeckner shares.

The Delisting Offer will not be subject to any closing conditions and will not include a minimum acceptance threshold. It will be made pursuant to the terms and conditions set forth in the Delisting Offer Document to be reviewed by the German Federal Financial Supervisory Authority (BaFin). Following BaFin approval, the Delisting Offer Document and all further information regarding the Delisting Offer will be published in accordance with the German Securities Acquisition and Takeover Act at <u>www.strong-for-good.com</u>. Further details regarding the Delisting Offer and the expected timetable will be announced with the publication of the offer document.

The 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 press release 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 the bidder and Kloeckner included elsewhere, including in the 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 United States companies or companies from other jurisdictions outside the Federal Republic of Germany. The Delisting Offer will not be 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 will be 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 will be 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, waiver of conditions and timing of payments, which are different from those of the United States. The Delisting Offer will be made to Kloeckner's shareholders resident in the United States on the same terms and conditions as those made to all other shareholders of Kloeckner to whom an offer is made. Any informational documents, including this press release, will be disseminated to U.S. shareholders on a basis comparable to the method that such documents are provided to the Kloeckner's other shareholders. To the extent that the Delisting Offer is subject to United States 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 the 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.
