RedHill Biopharma Announces Closing of Up To $19.4 Million Private Placement

The upfront proceeds are expected to strengthen RedHill's near-term liquidity and support a strategic, transformative, potential acquisition of commercial-stage, revenue-generating pharmaceutical product assets, which, if completed, would significantly expand the Company's commercial portfolio and revenue base. No definitive acquisition agreement has been executed, and the potential transaction remains subject to various conditions. There can be no assurance that any such transaction will be completed.

H.C. Wainwright & Co. acted as the exclusive placement agent for the offering.

The gross proceeds to the Company from this offering were approximately $6 million, before deducting the placement agent's fees and other offering expenses payable by the Company. The potential additional gross proceeds to the Company from the series A-1 warrants and the series A-2 warrants, if fully exercised on a cash basis, will be approximately $13.4 million. No assurance can be given that any of the series warrants will be exercised, or that the Company will receive cash proceeds from the exercise of the series warrants.

The securities described above were offered in a private placement under Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"), and/or Regulation D promulgated thereunder and, along with the ordinary shares of the Company represented by ADSs underlying the warrants, have not been registered under the Securities Act or applicable state securities laws. Accordingly, the securities issued in the private placement and ordinary shares of the Company represented by ADSs underlying the warrants may not be offered or sold in the United States except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act and such applicable state securities laws. Pursuant to a registration rights agreement with the investors, the Company has agreed to file a resale registration statement covering the securities described above (such date of effectiveness of the resale registration statement, the "Effectiveness Date").

This press release shall not constitute an offer to sell or a solicitation of an offer to buy these securities, nor shall there be any sale of these securities in any state or other jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or other jurisdiction.
