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 Klöckner shares. The final provisions relating to the takeover offer are disclosed in the offer document, as amended. BidCo reserves the right to deviate from the key points set out herein and in the offer document, as amended, in the final terms of the takeover offer to the extent legally permissible. Investors and Klöckner shareholders are strongly advised to read the offer document, as amended, and all other documents relating to the takeover offer, as they contain important information.

The Offer (as amended, "takeover offer") is being 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 takeover offer will not be 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 Klöckner 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, as amended, and any exemptions to be granted by the relevant regulatory authorities, no takeover offer will be 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 This Current Report on Form 8-K may not be published or otherwise distributed, in whole or in part, in any jurisdiction in which the takeover offer would be prohibited by applicable national law.

BidCo and its affiliates or affiliates of its financial advisor reserve 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 takeover 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 Klöckner 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 takeover 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 BidCo and the company included elsewhere, including in the offer document, as amended, has been and will be prepared in accordance with provisions applicable in the Federal Republic of Germany and has not been and will not be 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 takeover 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. Klöckner shareholders whose place of residence, incorporation or place of habitual abode is in the United States should note that the takeover offer is being 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 takeover offer is being 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 will be 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 takeover offer is being made to the company's shareholders resident in the United States on the same terms and conditions as those made to all other shareholders of the company 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 the company's other shareholders. To the extent that the takeover offer is subject to U.S. securities laws, such laws only apply to Klöckner shareholders in the United States, and no other person has any claims under such laws.

Any agreement concluded with BidCo as a result of the acceptance of the planned takeover offer will be 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 takeover offer under the U.S. Securities Act (or other laws known to them) because BidCo and the company 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.
