Forward-Looking Information 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 our ability to satisfy the closing conditions of the offering and the timing of the closing and the use of proceeds 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 suspension of the HST 001 program, the commencement of the planned HST 003 Phase 1/2 clinical trial for regeneration of cartilage in the knee, the anticipated filing of the HST 004 IND for spinal disc repair and the completion and reporting of topline data for the Phase 1 study of emricasan for the treatment of COVID-19; the nature, strategy and focus of Histogen’s business; the sufficiency of Histogen’s cash resources and its ability to achieve value for its stockholders, specifically given the strategic shift to orthopedic indications; the sufficiency of Amerimmune’s cash resources and its ability to complete the Phase 1 study of 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, HST 004 and the Collaborative Development and Commercialization Agreement with Amerimmune and any other collaboration agreements. 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: market and other conditions, 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 planned HST 003 Phase 1/2 clinical trial for regeneration of cartilage in the knee, 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, such as the emricasan Phase 1 study for the treatment of COVID-19; 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; and the requirement for additional capital to continue to advance these product candidates, which may not be available on favorable terms or at all. 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.
