Calliditas submits draft registration statement for the listing of ADSs in the U.S.

Calliditas Therapeutics AB (publ) (“Calliditas” or the “Company”) today announces that it has confidentially submitted a draft registration statement on Form F-1 to the U.S. Securities and Exchange Commission (the “SEC”) relating to a potential initial public offering of American Depositary Shares (“ADSs”) in the U.S. (a “U.S. IPO”) representing Calliditas’ common shares and listing of ADSs on the Nasdaq Stock Market (“Nasdaq”). The number of ADSs that may be offered, the number of underlying common shares that may be issued and the price for such instruments have not yet been determined.

This press release does not constitute an offer to sell or the solicitation of an offer to buy any securities. Any offers, solicitations or offers to buy, or any sales of securities will be made in accordance with the registration requirements of the Securities Act of 1933, as amended (“Securities Act”). This announcement is being issued in accordance with Rule 135 under the Securities Act.

Required Disclosures and Contact Information:

On January 9, 2020, the Board of Directors of the Company determined to investigate whether there are conditions to support a potential offering of the Company’s securities in the United States. The Company’s confidential submission of the draft registration statement is a first step toward such potential U.S. IPO which, if achieved, is intended to facilitate the Company’s access to the U.S. public capital markets. Even if the Board of Directors determines to proceed with the potential U.S. IPO, the offering may not be consummated. The potential U.S. IPO will not commence until the SEC and Nasdaq complete their respective review processes, and any such offering remains subject to market conditions, investor demand and shareholder approval. The Company intends to maintain the listing of its common shares on Nasdaq Stockholm, where they are currently traded.

Certain statements contained in this press release constitute “forward-looking statements.” These forward-looking statements represent the Company’s expectations or beliefs concerning future events, and it is possible that the results described in this press release will not be achieved. These statements include, but are not limited to, statements regarding the pursuit of the potential U.S. IPO, including the timing and outcome of SEC and Nasdaq review, the terms of the securities which may be sold in any such offering, shareholders’ approval related thereto, the timing and occurrence of any such offering and, if achieved, the expected benefits thereof. These forward-looking statements are subject to risks, uncertainties and other factors, many of which are outside of the Company’s control, including market and other conditions, that could cause actual results to differ materially from the intentions discussed in the forward-looking statements.

Any forward-looking statement speaks only as of the date on which it is made, and, except as required by law, the Company does not undertake any obligation to update or revise any forward-looking statement, whether as a result of new information, future events or otherwise. New factors emerge from time to time, and it is not possible for the Company to predict all such factors.
