Description of Business and Basis of Presentation	1. Description of Business and Basis of Presentation Organization Aridis Pharmaceuticals, Inc. (the “Company” or “we” or “our”) was established as a California limited liability corporation in 2003. The Company converted to a Delaware C corporation on May 21, 2014. Our principal place of business is in San Jose, California. We are a late-stage biopharmaceutical company focused on developing new breakthrough therapies for infectious diseases and addressing the growing problem of antibiotic resistance. The Company has a deep, diversified portfolio of clinical and pre-clinical stage non-antibiotic anti-infective product candidates that are complimented by a fully human monoclonal antibody discovery platform technology. The Company’s suite of anti-infective product candidates offers opportunities to profoundly alter the current trajectory of increasing antibiotic resistance and improve the health outcome of many of the most serious life-threatening infections particularly in hospital settings. Basis of Presentation and Consolidation The accompanying condensed consolidated financial statements (unaudited) include the amounts of the Company and our wholly-owned subsidiaries and have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The condensed consolidated financial statements (unaudited) have been prepared on the same basis as the annual financial statements. In the opinion of management, the accompanying condensed consolidated financial statements (unaudited) reflect all adjustments (consisting only of normal recurring adjustments) considered necessary for a fair presentation. These condensed consolidated financial statements (unaudited) should be read in conjunction with the audited consolidated financial statements and notes thereto for the preceding fiscal year included in the Company’s Annual Report on Form 10-K filed with the United States Securities and Exchange Commission (“SEC”) on April 8, 2020.

Reclassifications Certain prior period amounts have been reclassified to conform to the current period presentation. These reclassifications had no effect on previously reported condensed consolidated balance sheet, net loss, stockholders’ equity (deficit) or cash flow activities. COVID-19 The COVID-19 outbreak in the United States has caused business disruption. The extent of the impact of COVID-19 on the Company’s operational and financial performance will depend on certain developments, including the duration and spread of the outbreak, and impact on the Company’s clinical trials, employees and vendors, all of which are uncertain and cannot be predicted. At this point, the extent to which COVID-19 may impact the Company’s financial condition or results of operations is uncertain. Going Concern The Company has had recurring losses from operations since inception and negative cash flows from operating activities during the nine months ended September 30, 2020. Management expects to incur additional operating losses and negative cash flows from operations in the foreseeable future as the Company continues its product development programs. At September 30, 2020, the Company had cash and cash equivalents of $6.2 million. In October 2020, the Company received gross proceeds of $8.5 million from a registered direct equity financing (see Note 13). The Company's research and development expenses and resulting cash burn during the nine months ended September 30, 2020, were largely due to costs associated with the Phase 3 study of AR-301 for the treatment of ventilator associated pneumonia (“VAP”) caused by the Staphylococcus aureus bacteria and the Phase 1/2 study of AR-501 for the treatment of chronic lung infections associated with cystic fibrosis. Current clinical development activities are focused on AR-301, AR-501 and AR-711. We expect our expenses to continue to increase in connection with our ongoing development activities, particularly as we continue the research, development and clinical trials of, and seek regulatory approval for, our therapeutic candidates. On March 11, 2020, the World Health Organization declared the COVID-19 outbreak a pandemic. The COVID-19 pandemic is affecting the United States and global economies and may affect the Company’s operations and those of third parties on which the Company relies, including by causing disruptions in the supply of the product candidates and the conduct of current and future clinical trials. Additionally, as 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 our ability to access capital, which could negatively impact the Company’s short-term and long-term liquidity. These effects could have a material impact on the Company’s liquidity, capital resources, operations and business and those of the third parties on which the Company relies. The Company plans to fund its losses from operations through current cash on hand and future debt and equity financings which we may obtain through one or more public or private equity offerings, debt financings, government or other third-party funding, strategic alliances and licensing or collaboration arrangements. The Company may be unable to secure additional financing or other sources of funding on acceptable terms, or at all. If the Company is unable to obtain funding, the Company could be forced to delay, reduce or eliminate its research and development programs or future commercialization efforts, which could adversely affect its future business prospects and its ability to continue as a going concern. The Company believes that its current available cash and cash equivalents, along with the additional cash received in October 2020 from the equity financing, will not be sufficient to fund its planned expenditures and meet the Company’s obligations for at least the one-year period following its condensed consolidated financial statement issuance date. The accompanying condensed consolidated financial statements have been prepared on a going concern basis that contemplates the realization of assets and discharge of liabilities in their normal course of business. There is substantial doubt about the Company’s ability to continue as a going concern for one year after the date that these condensed consolidated financial statements are issued. These condensed consolidated financial statements do not include any adjustments that might be necessary from the outcome of this uncertainty.
