Forward-Looking Statements

This press release contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 and other Federal securities laws. For example, we are using forward-looking statements when we discuss the intended use of net proceeds from the private placement, as well as, Histogen’s future operations and its ability to successfully initiate and complete clinical trials, obtain clinical trial data and achieve regulatory milestones and related timing, including those related to the completion and reporting of top-line data for the HST 003 Phase 1/2 clinical trial for regeneration of cartilage in the knee, the completion of IND enabling activities and the anticipated filing of the HST 004 IND for spinal disc repair and the timing of providing clinical development guidance on the emricasan clinical program for the treatment of COVID-19; the nature, strategy and focus of Histogen’s business; the sufficiency of Histogen’s cash resources based on anticipated cash needs and its ability to achieve value for its stockholders, specifically given the strategic shift to orthopedic indications; Amerimmune’s ability to further develop emricasan and achieve value for Histogen’s stockholders; and the development and commercial potential and potential benefits of any of Histogen’s product candidates, such as HST 003 and HST 004. Histogen may not actually achieve the plans, carry out the intentions or meet the expectations or projections disclosed in the forward-looking statements and you should not place undue reliance on these forward-looking statements. Because such statements deal with future events and are based on Histogen’s current expectations, they are subject to various risks and uncertainties and actual results, performance or achievements of Histogen that could differ materially from those described in or implied by the statements in this press release, including: the uncertainties associated with the clinical development and regulatory approval of Histogen’s product candidates, including potential delays in the commencement, enrollment and completion of clinical trials, such as the completion and reporting of top-line data for the HST-003 Phase 1/2 clinical trial for regeneration of cartilage in the knee, the completion of IND enabling activities and the anticipated filing of the HST 004 IND for spinal disc repair and Amerimmune’s ability to further develop emricasan for the treatment of COVID-19, including the complexity and length of studies required to commercialize emricasan for COVID-19 and potential delays in the completion of clinical trials; Histogen’s dependence on its collaboration partner, Amerimmune, to carry out the development of emricasan and the potential for delays in the timing of regulatory approval; competition in the orthopedics market, COVID-19 market and other markets in which Histogen and its collaboration partner operate; the potential that earlier clinical trials and studies of Histogen’s product candidates may not be predictive of future results; risks related to business interruptions, including the outbreak of COVID-19 coronavirus, which could seriously harm Histogen’s financial condition and increase its costs and expenses; the requirement for additional capital to continue to advance these product candidates, which may not be available on favorable terms or at all; and market and other conditions. The foregoing review of important factors that could cause actual events to differ from expectations should not be construed as exhaustive and should be read in conjunction with statements that are included herein and elsewhere, including those risks discussed in Histogen’s filings with the Securities and Exchange Commission. Except as otherwise required by law, Histogen disclaims any intention or obligation to update or revise any forward-looking statements, which speak only as of the date hereof, whether as a result of new information, future events, or circumstances or otherwise.
