Risks Related to Covid-19 Pandemic The outbreak of COVID-19 has spread worldwide. On March 11, 2020, the World Health Organization declared the outbreak a pandemic. The COVID-19 pandemic is affecting the United States and global economies and may affect the Companys operations and those of third parties on which the Company relies. While the potential economic impact brought by, and the duration of, the COVID-19 pandemic is difficult to assess or predict, the impact of the COVID-19 pandemic on the global financial markets may reduce the Companys ability to access capital, which could negatively impact the Companys long-term liquidity. The ultimate impact of the COVID-19 pandemic is highly uncertain and subject to change. The Company does not yet know the full extent of potential delays or impacts on its business, clinical trials or the drug procurement, financing or other activities or on healthcare systems or the global economy as a whole. However, these effects could have a material impact on the Companys liquidity, capital resources, operations and business and those of the third parties on which we rely.
