Nature of Operations and Liquidity | 1. Nature of Operations and Liquidity Catalyst Biosciences, Inc. and its subsidiary (the “Company” or “Catalyst”) was a biopharmaceutical company with expertise in protease engineering. Prior to ceasing research and development activities in March 2022, the Company had several protease assets that were designed to address unmet medical needs in disorders of the complement or coagulation systems. As discussed below, the Company recently completed a purchase agreement to acquire a clinical-stage drug candidate for the treatment of NASH (nonalcoholic steatohepatitis, a severe form of nonalcoholic fatty liver disease). Concurrent with this purchase agreement, the Company entered into a separate business combination agreement to acquire an indirect controlling interest in a China-based pharmaceutical company. The Company is located in South San Francisco, California and operates in one segment. On May 19, 2022, Catalyst entered into and closed on an asset purchase agreement with Vertex Pharmaceuticals Inc. (“Vertex”), pursuant to which Vertex acquired Catalyst’s complement portfolio, including CB 2782-PEG and CB 4332, as well as its complement-related intellectual property including the ProTUNE TM and ImmunoTUNE TM platforms. See Note 11, Restructuring. On February 27, 2023, Catalyst entered into and closed on an asset purchase agreement with GC Biopharma Corp. (“GCBP”), pursuant to which GCBP acquired Catalyst’s legacy rare bleeding disorder program, including the coagulation related assets marzeptacog alfa (activated) (“MarzAA”), dalcinonacog alfa (“DalcA”), and CB-2679d-GT. See Note 11, Restructuring. F351 Asset Acquisition On December 26, 2022, the Company executed and closed an Asset Purchase Agreement, which was amended on March 29, 2023 (the “F351 Agreement”), with GNI Group Ltd. (“GNI Japan”) and GNI Hong Kong Limited to purchase all of the assets and intellectual property rights primarily related to the proprietary Hydronidone compound (collectively, the “F351 Assets”), other than such assets and intellectual property rights located in the People’s Republic of China. At the closing of the agreement on December 26, 2022, the Company paid $35.0 million in the form of 6,266,521 shares of Catalyst common stock and 12,340 shares of newly designated Series X redeemable convertible preferred stock (“Catalyst Convertible Preferred Stock”). Each share of Catalyst Convertible Preferred Stock is convertible into 10,000 shares of common stock, subject to stockholder approval under Nasdaq rules and subject to a beneficial ownership conversion blocker. For additional information, see Note 3, F351 Asset Acquisition. Business Combination Agreement Concurrent with the F351 Asset acquisition, the Company signed a definitive agreement, as amended on March 29, 2023, with GNI Group Ltd., GNI Hong Kong Limited, GNI USA, Inc., Continent Pharmaceuticals Inc. and Shanghai Genomics, Inc. (collectively, “GNI”) and other minority stockholders to acquire an indirect controlling interest in Beijing Continent Pharmaceutical Co Ltd. (“BC”), a commercial-stage pharmaceutical company based in China and majority-owned subsidiary of GNI, in exchange for newly issued shares of common stock (the “Business Combination Agreement”). The closing of the transactions under the Business Combination Agreement will be subject to stockholder approval at a stockholder meeting expected to be held on August 29, 2023 and certain customary closing conditions. For additional information, see Note 8, Commitments and Contingencies. Contingent Value Rights Agreement Pursuant to the Business Combination Agreement, on December 26, 2022, Catalyst and the Rights Agent (as defined therein) executed a contingent value rights agreement, as amended on March 29, 2023 (the “CVR Agreement”), pursuant to which each holder of Catalyst common stock as of January 5, 2023, excluding GNI (the “CVR Holders”), received one contractual contingent value right (a “CVR”) issued by the Company for each share of Catalyst common stock held by such holder. Each CVR entitles the holder thereof to receive certain cash payments in the future. For additional information, see Note 8, Commitments and Contingencies. Liquidity On January 12, 2023, the Company paid a one-time cash dividend of $0.24 per share to the Company’s common stockholders of record as of close of business on January 5, 2023, excluding GNI. The aggregate amount of the special dividend payment was approximately $7.6 million. On March 8, 2023, the Company distributed the net cash proceeds received from the GCBP asset sale of $0.2 million, or $0.01 per share, to the CVR Holders. See Note 11, Restructuring, for additional information regarding this distribution. On June 5, 2023, the Company distributed the net cash proceeds received from the Vertex hold-back amount of $3.5 million, or $0.11 per share, to the CVR Holders. See Note 11, Restructuring, for additional information regarding this distribution. The Company had a net loss of $2.2 million for the six months ended June 30, 2023. As of June 30, 2023, the Company had an accumulated deficit of $413.1 million and cash and cash equivalents of $6.9 million. Its primary uses of cash are to fund operating expenses and general and administrative expenditures. As part of the F351 Agreement, the Company issued 12,340 shares of Catalyst Convertible Preferred Stock, which upon stockholder approval, will be converted to 123,400,000 shares of common stock, subject to applicable beneficial ownership limitations. The terms of the Catalyst Convertible Preferred Stock include a cash settlement feature which provide that, if the Company’s stockholders fail to approve the conversion of the Catalyst Convertible Preferred Stock by September 30, 2023, the Company could be required to make cash payments to the holders of Catalyst Convertible Preferred Stock significantly in excess of its current liquidity. The Company believes that stockholders who are entitled to vote on the conversion proposal at the Company’s 2023 Annual Meeting of Stockholders, which is expected to be held on August 29, 2023, will vote to approve the proposal. However, as the vote of the Company’s common stockholders is outside of the control of the Company, there is substantial doubt about its ability to continue as a going concern for at least 12 months following the issuance of these condensed consolidated financial statements. The accompanying condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The condensed consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.
