ORGANIZATION AND OPERATIONS	ORGANIZATION AND OPERATIONS Nature of Business Salarius Pharmaceuticals, Inc. (“Salarius” or the “Company”), together with its subsidiaries, Salarius Pharmaceuticals, LLC, Flex Innovation Group LLC, and TK Pharma, Inc., is a clinical-stage biopharmaceutical company focused on developing effective treatments for cancers with high, unmet medical need. Specifically, the Company is developing treatments for cancers caused by dysregulated gene expression, i.e., genes that are incorrectly turned on or off. The field concerned with gene expression regulation is called ‘epigenetics’. As cancers are often diseases driven by gene dysregulation, epigenetics is an area of interest for cancer treatment. The Company's lead epigenetic based technology was licensed from the University of Utah Research Foundation in 2011. The Company is located in Houston, Texas. Risks Related to Covid-19 Pandemic The COVID-19 pandemic is significantly affecting the United States, global economies, and businesses worldwide. While the potential magnitude and duration of the economic and social impact of the COVID-19 pandemic is difficult to assess or predict, the impact on the global financial markets may, in the future, reduce our ability to access capital, which could negatively impact our short-term and long-term liquidity. At this time we are experiencing minimal disruption to our clinical trials. However, our ongoing Phase 1/2 Ewing sarcoma clinical trial and Phase 1/2 AST clinical trial may encounter delays in enrolling new patients due to concerns or healthcare resource constraints because of the COVID-19 pandemic. In addition, although at this time we have experienced no disruptions to manufacturing capabilities, certain aspects of our supply chain may be disrupted as certain of our third party suppliers and manufacturers have paused their operations in response to the COVID-19 pandemic or have otherwise encountered delays in providing supplies and services. The COVID-19 pandemic could also have a material and negative impact on our liquidity, capital resources (including our ability to secure additional financing if and when needed), our business and operations, and our workforce, as well as those of the third parties with which we do business or upon which we rely. While the situation is fluid and we do not yet know the full extent of potential delays or impacts on us or on healthcare systems or the global economy in general, we have worked to adapt to the unexpected and challenging circumstances resulting from the COVID-19 pandemic. However, we may experience disruptions in the future that have and could further adversely impact our business operations as well as our preclinical studies and clinical trials.
