Item 4 — Purpose of Transaction
KfW was mandated by the federal government of the Federal Republic of Germany pursuant to and in accordance with article 2 paragraph 4 of the KfW Law (Zuweisungsgeschaft) to enter into the Tender and Support Agreement to facilitate the disposition of its Common Shares to the Buyer pursuant to the terms of a Purchase Agreement between the Buyer and the Issuer dated June 12, 2025 (the "Purchase Agreement") and the exchange offer described therein (the "Exchange Offer"). Under the mandate, KfW is fully covered by the Federal Republic of Germany against any economic risks resulting from its investment. The Purchase Agreement provides for, among other things (a) the Buyer to commence the Exchange Offer to acquire (subject to a minimum condition described in the Purchase Agreement) any and all of the outstanding ordinary shares, par value Euros 0.12 per share, of the Issuer for the consideration and upon the terms and subject to the conditions set forth in the Purchase Agreement and (b) following the consummation of the Exchange Offer, a post-offer reorganization of the Issuer. The Tender and Support Agreement requires KfW to, among other things (i) tender all of its Common Shares into the Exchange Offer, subject to the transfer restrictions set forth in the Shareholders Agreement described in Item 6 being lifted; (ii) vote in favor of the proposals set forth in Section 2.04 of the Purchase Agreement and any proposal to facilitate the Exchange Offer submitted by the Issuer for approval by the Issuer's shareholders and recommended by its management and supervisory boards, and against any proposal, action or agreement for an Alternative Acquisition Proposal (as defined in the Purchase Agreement) or having certain adverse effects on the Exchange Offer or post offer reorganization, in each case subject to the voting restrictions in the Shareholders Agreement being lifted; (iii) agree to certain other restrictions on its ability to take actions with respect to the Issuer and the Common Shares; and (iv) waive it right of first refusal under the Shareholders' Agreement in connection with the Exchange Offer and agree to, subject to and with effect as of Closing (as defined in the Purchase Agreement) and subject to certain conditions under the Tender and Support Agreement, terminate the Shareholders' Agreement, the relationship agreement dated July 17, 2020 among the Issuer, KfW and dievini (the "Relationship Agreement"), and - with effect for itself - the investment and shareholders' agreement dated July 17, 2020 between the Issuer and its pre-IPO shareholders. KfW intends to provide in the termination agreements of the Shareholders' Agreement and the Relationship Agreement that, in the event of any inconsistency between the Shareholders' Agreement, respectively the Relationship Agreement, and the Tender and Support Agreement, the Tender and Support Agreement shall prevail for so long as the Shareholders' Agreement, respectively the Relationship Agreement, has not been terminated. The foregoing descriptions of the Purchase Agreement and the Tender and Support Agreement, and the respective transactions contemplated thereby, do not purport to be complete and are qualified in their entirety by reference to such agreements. A copy of the Purchase Agreement, listed as Exhibit 1 hereto, is incorporated by reference to Exhibit 99.1 to the Issuer's Current Report on Form 6-K filed with the SEC on June 16, 2025.
