Molecular Partners Announces Launch of American Depositary Shares (ADS) Offering in the United States

Zurich-Schlieren, Switzerland, June 9, 2021. Molecular Partners AG (SIX: MOLN), a clinical-stage biotech company developing a new class of custom-built protein drugs known as DARPin^® therapeutics, today announced that it has commenced an initial public offering in the United States of 3,000,000 American Depositary Shares (“ADSs”) pursuant to a registration statement on Form F-1 (File No. 333-255447), as amended, that has been filed with the U.S. Securities and Exchange Commission (the “Offering”). In connection with the Offering, Molecular Partners expects to grant the underwriters a 30-day option to purchase additional ADSs of up to 15% of the total number of ADSs placed in the Offering (i.e. up to 450,000 additional ADSs). Each ADS will represent one Molecular Partners ordinary share. The new ordinary shares underlying the ADSs will be issued from Molecular Partners’ authorized capital under exclusion of the existing shareholders’ pre-emptive rights. The terms of the Offering have not been determined, and the Offering is subject to market and other conditions, and there can be no assurance as to whether or when the Offering may be completed or as to the actual size or terms of the Offering.

The number of ADSs to be offered and the price for the ADSs in the proposed Offering will be determined on the pricing date (expected for the week of June 14, 2021). The final price of the offered ADSs will be determined largely on the basis of the closing price of Molecular Partners’ shares on the Swiss Stock Exchange on the pricing date translated into U.S. dollars at the then prevailing exchange rate and using an ADS to share ratio of one to one. Application has been made to list the ADSs on the Nasdaq Global Market in the United States under the ticker symbol “MOLN” and the new ordinary shares underlying the ADSs on the SIX Swiss Exchange (“SIX”). The new shares will rank pari passu with Molecular Partners’ existing shares which are already listed on the SIX pursuant to the International Reporting Standard.

J.P. Morgan, SVB Leerink and Cowen are acting as joint book-running managers for the proposed offering. RBC Capital Markets is acting as the bookrunner for the proposed offering. Kempen & Co is acting as the lead manager for the proposed offering.
