Nature of Business and Liquidity
Nature of Business and Liquidity	(1) Nature of Business and Liquidity Annovis Bio, Inc. (the “Company” or “Annovis”) was incorporated on April 29, 2008, under the laws of the State of Delaware. Annovis is a clinical-stage drug platform company addressing neurodegeneration such as Alzheimer’s disease (“AD”), Parkinson’s disease (“PD”) and Down syndrome patients with AD (“DS-AD”). The toxic cascade in neurodegeneration begins with high levels of neurotoxic proteins which lead to impaired axonal transport, inflammation, death of nerve cells and loss of cognition and motor function. The Company’s lead compound, Buntanetap, is a small molecule administered orally that attacks neurodegeneration by entering the brain and inhibiting the translation of multiple neurotoxic proteins thereby impeding the toxic cascade. Since its founding, the Company has been engaged in organizational activities, including raising capital, and research and development activities. The Company has not generated substantial revenues and has not yet achieved profitable operations, nor has it ever generated positive cash flows from operations. There is no assurance that profitable operations, if achieved, could be sustained on a continuing basis. The Company is subject to those risks associated with any clinical stage pharmaceutical company that has substantial expenditures for research and development. There can be no assurance that the Company’s research and development projects will be successful, that products developed will obtain necessary regulatory approval, or that any approved product will be commercially viable. In addition, the Company operates in an environment of rapid technological change and is largely dependent on the services of its employees and consultants. Further, the Company’s future operations are dependent on the success of the Company’s efforts to raise additional capital. The Company has a history of incurring net losses and anticipates incurring additional losses until such time, if ever, that it can generate significant revenue from its product candidates currently in development. The Company’s primary source of capital has been the issuance of equity securities. The Company closed its initial public offering (the “IPO”) on January 31, 2020, pursuant to which it sold a total of 2,300,000 shares of common stock at an initial offering price of $6.00 per share for total gross proceeds of approximately $13.8 million. The net proceeds of the IPO were approximately $12.0 million after deducting underwriting discounts and issuance costs paid by the Company. In conjunction with the IPO, the Company granted the underwriters 100,000 warrants to purchase shares of Company common stock at an exercise price of $7.50 per share, which is 125% of the initial public offering price. Upon the closing of the IPO, outstanding redeemable convertible preferred stock and convertible promissory notes converted into shares of Company common stock totaling 4,117,089 and 118,470, respectively. On May 26, 2021, the Company closed an underwritten public offering of 1,000,000 shares of its common stock at an offering price of $50.00 per share, for gross proceeds of $50.0 million. The net proceeds of the offering were approximately $46.6 million, after deducting underwriting discounts and issuance costs paid by the Company. The Company’s common stock trades on the New York Stock Exchange under the ticker symbol “ANVS”. As of the date these financial statements are issued, management believes that the current cash and cash equivalents are sufficient to fund operations and capital requirements for at least the next 12 months including one potential short-term clinical trial in AD and one potential short term clinical trial in PD. To fund additional planned Phase 3 trials, however, the Company will need to raise additional capital. There is no assurance that such financing will be available when needed or on acceptable terms.
