In conjunction with the royalty financing deal with HealthCare Royalty (HCRx) announced on January 30, 2025, GENFIT will request the consent of the holders of 2025 OCEANEs and proposes: to repurchase the 2025 OCEANEs at EUR 32.00 per bond from interested bondholders, or alternativelyto pay a consent fee of EUR 0.60 per bond still outstanding after the upcoming bondholder meeting and cancellation of the repurchased 2025 OCEANEs Both proposals are subject to approval of the royalty financing by the 2025 OCEANEs bondholders at the upcoming bondholders meeting and closing of the royalty financing Lille (France), Cambridge (Massachusetts, United States), Zurich (Switzerland), February 10, 2025 - GENFIT (Nasdaq and Euronext: GNFT), a biopharmaceutical company dedicated to improving the lives of patients with rare and life-threatening liver diseases, today announced the final terms of the 2025 OCEANEs repurchase proposal and the consent fee that would be paid to the holders of 2025 OCEANEs still outstanding after cancellation of repurchased 2025 OCEANEs. Context On January 30, 2025, GENFIT announced that it has entered into a non-dilutive capped royalty financing agreement (the “Royalty Financing”) with HealthCare Royalty (HCRx) for up to €185 million. This transaction significantly extends GENFIT’s cash runway, including after the repayment of its bonds convertible into new shares and/or exchangeable into existing shares due October 16, 2025 (the “2025 OCEANEs”). GENFIT also announced that it intended to offer to interested bondholders to repurchase their 2025 OCEANEs. In the Royalty Financing, HCRx will be compensated and repaid out of a portion of the royalties which GENFIT is eligible to receive on sales of Iqirvo® (elafibranor) pursuant to its long-term strategic partnership with Ipsen. To secure its obligations under the Royalty Financing, GENFIT will transfer the corresponding royalty receivables to a French law trust (fiducie-sûreté) for the benefit of the holders of the royalty financing bonds. The terms and conditions of the 2025 OCEANEs contain a negative pledge clause which limits GENFIT’s ability to grant security interests to its creditors on its present or future assets or revenues. Granting the fiducie-sûreté is not permitted under this clause. The closing of the Royalty Financing (i.e. the payment of the first €130 million under the Royalty Financing) is thus conditioned upon the holders of the 2025 OCEANEs approving an amendment to the negative pledge clause (the “Amendment of Terms”). If the Amendment of Terms is approved1, and the closing of the royalty financing is completed, GENFIT will pay a consent fee (the “Consent Fee”) to the holders of 2025 OCEANEs still outstanding after cancellation of the repurchased 2025 OCEANEs. Concurrently with the Amendment of Terms, GENFIT is proposing to repurchase the 2025 OCEANEs of any interested holder (the “Repurchase” and, together with the Amendment of Terms, the “Transaction”). Dual Proposal to the 2025 OCEANEs holders GENFIT and Natixis, its Solicitation Advisor, have collected feedback from the 2025 OCEANEs holders in order to set the definitive terms of the Transaction. GENFIT proposes: to repurchase 2025 OCEANEs at a price of EUR 32.00 per bond, or alternativelyto pay a Consent Fee of EUR 0.60 per 2025 OCEANE In the coming days, GENFIT will propose to all of the 2025 OCEANEs holders to enter into a Put Option Agreement, pursuant to which GENFIT will unconditionally and irrevocably undertake to repurchase the 2025 OCEANEs of such holder, subject to approval by the general meeting of the 2025 OCEANEs holders of the Amendment of Terms and the closing of the Royalty Financing. After execution of the Put Option Agreement, the holder will have until several days after the closing of the Royalty Financing to exercise its option under the Agreement. Holders of the 2025 OCEANEs who have not entered into the Put Option Agreement or who do not exercise their option will receive the Consent Fee. As stated above, both the Repurchase and the payment of the Consent Fee are subject to (i) the approval by the general meeting of the 2025 OCEANEs holders of the Amendment of Terms, and (ii) the closing of the Royalty Financing. 2025 OCEANEs holders interested in the Repurchase are invited to contact (i) with respect to qualified investors, GENFIT at investors@genfit.com or their usual sales contact at Natixis (the “Solicitation Advisor”), or at ld-m-equityflowsalescb@natixis.com or at ld-secm-syndicateteam@natixis.com, and (ii) with respect to retail holders, the 2025 OCEANEs Bondholders Representative (Représentant de la Masse) at genfit@aetherfs.com. The Consent Fee will only be paid after the Repurchase has taken place. 2025 OCEANEs that have been bought back by GENFIT as part of the Repurchase (or that have been converted prior to 5:00 p.m. (Paris time) on the date falling 2 business days prior to the date of payment of the Consent Fee) will thus not receive the Consent Fee. The terms and conditions of the 2025 OCEANEs contain a clean-up call option at par if the total number of 2025 OCEANEs still outstanding represents 15% or less of the number of 2025 OCEANEs originally issued (that is 912,162 2025 OCEANEs or less, compared to 1,902,698 2025 OCEANEs outstanding as of today). GENFIT undertakes that, following the Repurchase, it will not exercise this clean-up call option until the 2025 OCEANEs reach maturity. In the coming days, GENFIT will convene a general meeting of the 2025 OCEANEs holders, which is expected to be held in early March. A Consent Solicitation Memorandum will be published, together with the documents required by French law. The results of the general meeting and the closing of the Royalty Financing will be announced in two subsequent press releases. Natixis is acting as sole solicitation advisor to assist GENFIT to seek the consent of the holders of the 2025 OCEANEs and in the repurchase of the 2025 OCEANEs. CMS Francis Lefebvre is acting as legal advisor to GENFIT.
