Corvus is a clinical-stage biopharmaceutical company. The Company’s operations are located in South San Francisco, California. Presentation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries, Corvus Biopharmaceuticals, Ltd. and Corvus Hong Kong Limited. All intercompany accounts and transactions have been eliminated from the consolidated financial statements. Initial Public Offering On March 22, 2016, the Company’s registration statement on Form S-1 (File No. 333-208850) relating to its initial public offering (“IPO”) of its common stock was declared effective by the Securities and Exchange Commission (“SEC”) and the shares of its common stock began trading on the Nasdaq Global Market on March 23, 2016. The public offering price of the shares sold in the IPO was $15.00 per share. The IPO closed on March 29, 2016, pursuant to which the Company sold 4,700,000 shares of its common stock. On April 26, 2016, the Company sold an additional 502,618 shares of its common stock to the underwriters upon partial exercise of their over-allotment option, at the initial offering price of $15.00 per share. The Company received aggregate net proceeds of approximately $70.6 million, after underwriting discounts, commissions and offering expenses. Immediately prior to the consummation of the IPO, all outstanding shares of convertible preferred stock were converted into common stock. Follow-on Public Offering In March 2018, the Company completed a follow-on public offering in which the Company sold 8,117,647 shares of common stock at a price of $8.50 per share, which included 1,058,823 shares issued pursuant to the underwriters’ exercise of their option to purchase additional shares of common stock. The aggregate net proceeds received by the Company from the offering were approximately $64.9 million, net of underwriting discounts and commissions and offering expenses payable by the Company. In February 2021, the Company completed a follow-on public offering in which the Company sold 9,783,660 shares of common stock at a price of $3.50 per share, which included 1,212,231 shares issued pursuant to the underwriters’ exercise of their option to purchase additional shares of common stock. The aggregate net proceeds received by the Company from the offering were approximately $32.0 million, net of underwriting discounts and commissions and offering expenses. Registered Direct Offering On May 6, 2024, the Company completed a registered direct offering which resulted in gross proceeds of approximately $30.6 million. The financing consisted of the sale of 13,512,699 shares of common stock and accompanying common stock warrants to purchase 13,078,509 shares of common stock (or pre-funded warrants in lieu thereof) at a combined offering price of $1.7312 per share, and the sale of pre-funded warrants to purchase 4,144,085 shares of common stock and accompanying common warrants to purchase 4,010,927 shares of common stock (or pre-funded warrants in lieu thereof) at a combined offering price of $1.7311 per share. The common warrants have an exercise price of $3.50 per share of common stock (or $3.4999 per pre-funded warrant in lieu thereof), are exercisable at any time after the date of issuance, subject to certain ownership limitations, and expire on June 30, 2025. The pre-funded warrants have an exercise price of $0.0001 and are exercisable any time after the date of the issuance, subject to certain ownership limitations. During the year ended December 31, 2024, 5,311,198 of common stock warrants were exercised, resulting in aggregate proceeds of approximately $18.6 million received by the Company. Liquidity The Company is subject to risks and uncertainties common to early-stage companies in the biotechnology industry, including, but not limited to, development by competitors of new technological innovations, protection of proprietary technology, dependence on key personnel, contract manufacturer and contract research organizations, compliance with government regulations and the need to obtain additional financing to fund operations. Since commencing operations in 2014, the majority of the Company’s efforts have been focused on the research and development of soquelitinib, ciforadenant and mupadolimab. The Company believes that it will continue to expend substantial resources for the foreseeable future as it continues clinical development of, seek regulatory approval for and, if approved, prepare for the commercialization of soquelitinib, ciforadenant and mupadolimab, as well as product candidates under the Company’s other development programs. These expenditures will include costs associated with research and development, conducting preclinical studies and clinical trials, obtaining regulatory approvals, manufacturing and supply, sales and marketing and general operations. In addition, other unanticipated costs may arise. Because the outcome of any clinical trial and/or regulatory approval process is highly uncertain, the Company may not be able to accurately estimate the actual amounts necessary to successfully complete the development, regulatory approval process and commercialization of soquelitinib, ciforadenant and mupadolimab or any other product candidates. The Company has incurred significant losses and negative cash flows from operations in all periods since inception and had an accumulated deficit of $397.0 million as of December 31, 2024. To date, none of the Company’s product candidates have been approved for sale and therefore the Company has not generated any revenue from sales of commercial products. Management expects operating losses to continue for the foreseeable future. The Company has funded its operations to date primarily through the sale of redeemable convertible preferred stock and common stock. As of December 31, 2024, the Company had cash, cash equivalents and marketable securities of $52.0 million. The Company’s cash, cash equivalents and marketable securities are not sufficient to fund the Company’s planned operations for a period of at least 12 months from the date these consolidated financial statements are issued. To fund the Company's planned operations, the Company will need to raise additional capital. The Company intends to raise additional capital through private and public equity offerings, including its “at-the-market” offering program, debt financings, the potential exercise of common warrants outstanding with an exercise price of $3.50 per share and potential future collaboration, license and development agreements. However, there can be no assurance that the Company will be successful in acquiring additional funding at levels sufficient to fund its operations or on terms acceptable to the Company or at all. If the Company is unsuccessful in its efforts to raise additional capital or if sufficient funds on acceptable terms are not available when needed, the Company could be required to significantly reduce operating expenses and delay, reduce the scope of or eliminate one or more of its development programs, out-license intellectual property rights to its product candidates and sell unsecured assets, or a combination of the above, any of which may have a material adverse effect on the Company’s business, results of operations, financial condition and/or its ability to fund its obligations on a timely basis or at all. Failure to manage discretionary spending or raise additional capital, as needed, may adversely impact the Company’s ability to achieve its intended business objectives. These conditions raise substantial doubt about the Company’s ability to continue as a going concern for a period of one year from the date of the issuance of these consolidated financial statements. The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern, which contemplates the realization of assets and the settlement of liabilities and commitments in the normal course of business. The consolidated financial statements do not reflect any adjustments relating to the recoverability and classification of assets or the amounts and classification of liabilities that might be necessary if the Company is unable to continue as a going concern.
