INCHEON, South Korea and ZUG, Switzerland, Aug. 31, 2026 /PRNewswire/ -- Samsung Biologics (KRX: 207940.KS), a leading contract development and manufacturing organization (CDMO), through its direct Swiss subsidiary Samsung Peptide AG ("Samsung Peptide"), today published the tender offer prospectus ("Offer Prospectus") for all publicly held registered shares of PolyPeptide Group AG ("PolyPeptide").

PolyPeptide shareholders will receive CHF 44.31 net in cash for each PolyPeptide share, representing an implied aggregate equity value of approximately CHF 1.46 billion. The offer price represents a 40% premium compared with the unaffected price of PolyPeptide's shares on the SIX Swiss Exchange ("SIX") as of April 10, 2026, which was the last trading day prior to the publication of the first media speculation regarding a potential acquisition of PolyPeptide. The offer price represents a premium of 11.6% compared with the volume-weighted average share price over the last 60 trading days prior to the pre-announcement on July 20, 2026.

The Board of Directors of PolyPeptide, acting through its independent and non-conflicted members, unanimously recommends that PolyPeptide's shareholders accept the offer. The recommendation is further supported by an independent fairness opinion from IFBC AG.

Draupnir Holding B.V., PolyPeptide's largest individual shareholder, who holds approximately 55.65% of the total PolyPeptide shares outstanding (excluding treasury shares), has undertaken to tender all of its shares into the offer.

The main offer period commences on Sept. 15, 2026 and is expected to end on Oct. 12, 2026 at 4 p.m. Swiss time. The offer is subject to a minimum acceptance threshold of 66⅔% on a fully diluted share count basis (excluding treasury shares), applicable regulatory approvals, and other customary conditions described in the Offer Prospectus. The Offer Prospectus and further offer documentation is available on https://samsungbiologics.com/offer.

Following the settlement of the offer Samsung Peptide intends to pursue a squeeze-out of any remaining minority shareholders and to delist PolyPeptide's shares from the SIX.

United States of America

The Offer will be made for the registered shares of PolyPeptide, a Swiss company whose shares are listed on the SIX, and is subject to Swiss disclosure and procedural requirements, which are different from those of the United States of America (U.S.).

The Offer will be made in the U.S. pursuant to Section 14(e) of, and Regulation 14E under, the U.S. Securities Exchange Act of 1934, as amended (the U.S. Exchange Act), subject to the exemption provided by Rule 14d-1(c) under the U.S. Exchange Act (the Tier I Exemption) and Rule 14e-5(b)(10) under the U.S. Exchange Act and any exemptions that may be granted by the U.S. Securities and Exchange Commission (SEC), and otherwise in accordance with the requirements of Swiss law. Accordingly, the Offer will be subject to disclosure and other procedural requirements, including with respect to withdrawal rights, settlement procedures and timing of payments that are different from those applicable under U.S. domestic tender offer procedures and laws.

Any financial statements or figures included or referenced in the Offer Prospectus have been or will be prepared in accordance with the applicable accounting standards of, or recognized in, Switzerland and/or the Republic of Korea, which may not be comparable to the financial statements of U.S. companies.

In accordance with the laws of Switzerland and subject to applicable regulatory requirements, Samsung Biologics and its subsidiaries (including Samsung Peptide) and affiliates or their respective nominees or brokers (acting as agents for Samsung Peptide) may from time to time after the date of the Offer Prospectus, and other than pursuant to the Offer, directly or indirectly, purchase or arrange to purchase PolyPeptide shares or any securities that are convertible into, exchangeable for or exercisable for PolyPeptide shares from their holders who are willing to sell them outside the Offer from time to time, including purchases in the open market at prevailing prices or in private transactions at negotiated prices, and shall comply with applicable laws and regulations in Switzerland and applicable U.S. securities laws, rules and regulations, including Rule 14e-5 under the U.S. Exchange Act (subject to the exemption provided by Rule 14e-5(b)(10) under the U.S. Exchange Act).

Any information about such purchases or arrangements to purchase will be publicly disclosed in the U.S. on https://samsungbiologics.com/offer if and to the extent that such information is made public in accordance with the applicable laws and regulations of Switzerland. In addition, the financial advisor to PolyPeptide and, subject to applicable Swiss and U.S. securities laws, rules and regulations, including Rule 14e-5 under the U.S. Exchange Act (subject to the exemption provided by Rule 14e-5(b)(10) under the U.S. Exchange Act), the financial advisor to Samsung Biologics and its subsidiaries (including Samsung Peptide) and affiliates may also engage in ordinary course trading activities in securities of PolyPeptide, which may include purchases or arrangements to purchase such securities.

It may be difficult for holders of PolyPeptide shares in the U.S. (U.S. Holders) to enforce their rights and any claim they may have arising out of U.S. securities laws, since Samsung Peptide and PolyPeptide are located in non-U.S. jurisdictions, and some or all of their officers and directors may be residents of a non-U.S. jurisdiction. U.S. Holders may not be able to sue a non-U.S. company or its officers or directors in a U.S. or non-U.S. court for violations of the U.S. securities laws. Further, it may be difficult to compel a non-U.S. company and its affiliates to subject themselves to a U.S. court's judgment.

The receipt of cash pursuant to the Offer by a U.S. Holder may be a taxable transaction for U.S. federal income tax purposes and under applicable U.S. state and local laws, as well as foreign and other tax laws. Each shareholder of PolyPeptide is urged to consult his or her independent professional advisor immediately regarding the tax consequences of an acceptance of the Offer.

Neither the SEC nor any securities commission of any State of the U.S. has (a) approved or disapproved of the Offer; (b) passed upon the merits or fairness of the Offer; or (c) passed upon the adequacy or accuracy of the disclosure in this Offer Prospectus.
