| Description of Business, Organization and Liquidity | 1. Description of Business, Organization and Liquidity Business IO Biotech, Inc. is a clinical-stage biotechnology company dedicated to the identification and development of disruptive immune therapies for the treatment of cancer. As used in these financial statements, unless the context otherwise requires, references to the “Company”, “we,” “us,” and “our” refer to IO Biotech, Inc. and its subsidiaries. IO Biotech ApS was incorporated in Denmark in December 2014. We are developing novel, immune-modulating cancer vaccines based on our T-win technology platform. Corporate Reorganization In November 2021, we completed a corporate reorganization whereby IO Biotech ApS became a wholly-owned subsidiary of the Company. In connection with the corporate reorganization, each issued and outstanding Class A ordinary share ($ 0.16 par value) was exchanged on a one for one basis into shares of common stock of the Company ($ 0.001 par value). Each Class B and Class C preference share of IO Biotech ApS was exchanged on a one for one basis into shares of Class B and Class C preferred stock of the Company. Initial Public Offering (IPO) In November 2021, we completed our IPO, selling an aggregate of 8,222,500 shares of common stock at a price to the public of $ 14.00 per share, including 1,072,500 shares of common stock sold pursuant to the underwriters’ exercise of their option to purchase additional shares of common stock. We received net proceeds from the IPO, after deducting underwriting discounts and commissions and other offering costs of approximately $ 103.3 million. Immediately prior to the consummation of the IPO, all outstanding shares of our Class A ordinary shares and Class B and Class C convertible preference shares were converted into 20,592,413 shares of common stock. Upon the closing of the IPO on November 9, 2021, a total of 28,815,267 shares of common stock were outstanding. Our common stock began trading on the Nasdaq Global Market on November 5, 2021 under the symbol “IOBT.” On November 9, 2021, we amended and restated the certificate of incorporation of IO Biotech, Inc. to authorize 300,000,000 shares of common stock and 5,000,000 shares of preferred stock. The shares of preferred stock are currently undesignated. At-The-Market Equity Program On February 15, 2023, we filed a new prospectus supplement with the SEC with respect to the offer and sale of shares of our common stock, par value $ 0.001 per share, with an aggregate offering price of up to $ 19,500,000 , establishing an at-the-market equity program. On February 15, 2023, we also entered into a Sales Agreement by and between the Company and Cowen and Company, LLC for shares with an aggregate offering price of up to $ 75,000,000 through which we may, from time to time, sell shares to Cowen and Company, LLC. Any shares offered and sold through the at-the-market equity program will be issued pursuant to the Company’s Registration Statement on Form S-3 (File No. 333-269569), which was declared effective on February 10, 2023, the prospectus supplement related to the offering that forms a part of the registration statement, and any applicable prospectus supplements that may form a part of the registration statement in the future. The aggregate market value of shares eligible for sale under the prospectus supplement and under the Sales Agreement will be subject to the limitations of General Instruction I.B.6 of Form S-3, to the extent required under such instruction. Risks and Uncertainties We are subject to risks common to companies in the biotechnology industry including, but not limited to, new technological innovations, protection of proprietary technology, dependence on key personnel, compliance with government regulations and the need to obtain additional financing. Product candidates currently under development will require significant additional research and development efforts, including extensive pre-clinical and clinical testing and regulatory approval, prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel infrastructure and extensive compliance reporting capabilities. Our product candidates are in development. There can be no assurance that our research and development will be successfully completed, that adequate protection for our intellectual property will be obtained, that any products developed will obtain necessary government regulatory approval or that any approved products will be commercially viable. Even if our product development efforts are successful, it is uncertain when, if ever, we will generate significant revenue from product sales. We operate in an environment of rapid change in technology and substantial competition from pharmaceutical and biotechnology companies. In addition, we are dependent upon the services of our employees and consultants. Liquidity Considerations and Going Concern Basis of Accounting Since inception, we have devoted substantially all our efforts to business planning, conducting research and development, recruiting management and technical staff, and raising capital. We have financed our operations primarily through the issuance of convertible preference shares, convertible notes and, most recently, our IPO. Our continued discovery and development of product candidates will require significant additional research and development efforts, including extensive preclinical and clinical testing and regulatory approval prior to commercialization. These efforts require significant amounts of additional capital, adequate personnel and infrastructure and extensive compliance-reporting capabilities. Even if product development efforts are successful, it is uncertain when, if ever, we will realize significant revenue from product sales. As of March 31, 2023, we had an accumulated deficit of $ 194.8 million. We have incurred losses and negative cash flows from operations since inception, including net losses of $ 17.0 million and $ 71.5 million for the three months ended March 31, 2023 and the year ended December 31, 2022, respectively. We expect that our operating losses and negative cash flows will continue for the foreseeable future as we continue to develop our product candidates. We currently expect that our cash and cash equivalents of $ 128.5 million as of March 31, 2023 will be sufficient to fund our operating expenses and capital requirements for at least 12 months from the date the financial statements are issued. On this basis, the condensed consolidated financial statements are prepared on a going concern basis of accounting. However, additional funding will be necessary to fund future discovery research, pre-clinical and clinical activities. We will seek additional funding through public financings, debt financings, collaboration agreements, strategic alliances and licensing arrangements. Although we have been successful in raising capital in the past, there is no assurance that we will be successful in obtaining such additional financing on acceptable terms, or at all, and we may not be able to enter into collaborations or other arrangements. If we are unable to obtain funding, we could be forced to delay, reduce or eliminate our research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect our business prospects, even our ability to continue operations. Coronavirus Pandemic Although the World Health Organization has declared that COVID-19 no longer represents a global health emergency, the actual and perceived impact of COVID-19 and any effect on our business cannot be predicted. As a result, there can be no assurance that we will not experience additional negative impacts associated with COVID-19, which could be significant. The COVID-19 pandemic may negatively impact our business, financial condition and results of operations causing interruptions or delays in the Company’s programs and services. |
