Summary of Significant Accounting Policies | 2. Summary of Significant Accounting Policies ​ Basis of Presentation ​ The accompanying condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). The Company’s functional and reporting currency is the U.S. dollar, except for its investment in its equity method investee which is the Chinese renminbi (RMB). The accompanying condensed consolidated financial statements have been prepared on a going-concern basis, which contemplates the realization of assets and discharge of liabilities in the normal course of business. ​ Unaudited Interim Financial Information ​ The accompanying interim condensed consolidated financial statements and related disclosures are unaudited, have been prepared on the same basis as the annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for fair statement of the condensed consolidated financial statements presented. ​ The condensed consolidated balance sheet as of December 31, 2025 was derived from audited financial statements, but does not include all disclosures required by GAAP. The condensed consolidated results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the full year or for any other future year or interim period. The accompanying condensed consolidated financial statements should be read in conjunction with the audited financial statements and the related notes for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 12, 2026. ​ Use of Estimates ​ The preparation of the Company’s condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Actual results could differ from such estimates. ​ Investments in Equity Securities The Company uses the equity method of accounting for its equity investment if the investment provides the ability to exercise significant influence, but not control, over operating and financial policies of the investee. The Company’s proportionate share of the net income (loss) resulting from the equity method investment is reported under the line item captioned “income (loss) from equity method investment” in the condensed consolidated statements of operations and comprehensive loss and the carrying value of the equity method investments is reported under the line captioned “Investment in Angel Pharmaceuticals” in the condensed consolidated balance sheets. The Company’s equity method investments are reported at cost and adjusted each period for the Company’s share of the investee’s income or loss and the foreign currency translation adjustment as applicable. For equity method investees with a functional currency different than the Company’s reporting currency, the Company follows the guidance under Accounting Standards Codification (“ASC”) 830-10-15-5, pursuant to which, the foreign currency financial statements of a foreign investee accounted for by the equity method should be translated to the reporting entity’s reporting currency. The Company evaluates equity method investments for impairment whenever events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by the Company when reviewing an equity method investment for impairment include the length of time (duration) and the extent (severity) to which the fair value of the equity method investment has been less than cost, the investee’s financial condition and near-term prospects and the intent and ability to hold the investment for a period of time sufficient to allow for anticipated recovery. An impairment that is other-than-temporary is recognized in the period identified. ​ See Note 6, “Equity Method Investment,” for further information. ​ Concentrations of Credit Risk and Other Risks and Uncertainties ​ Substantially all of the Company’s cash and cash equivalents are deposited in accounts with two financial institutions that management believes are of high credit quality. Such deposits may, at times, exceed federally insured limits. The Company maintains its cash with an accredited financial institution and accordingly, such funds are subject to minimal credit risk. The Company’s marketable securities consist of investments in U.S. Treasury securities and U.S. government agency securities, which can be subject to certain credit risks. However, the Company mitigates the risks by investing in high-grade instruments, limiting its exposure to any one issuer, and monitoring the ongoing creditworthiness of the financial institutions and issuers. The Company has not experienced any losses on its deposits of cash, cash equivalents or marketable securities. ​ The Company is subject to a number of risks similar to other early stage biopharmaceutical companies, including, but not limited to, the need to obtain adequate additional funding, possible failure of preclinical testing or clinical trials, its reliance on third parties to conduct its clinical trials, the need to obtain marketing approval for its product candidates, competitors developing new technological innovations, the need to successfully commercialize and gain market acceptance of the Company’s product candidates, its right to develop and commercialize its product candidates pursuant to the terms and conditions of the licenses granted to the Company, and protection of proprietary technology. If the Company does not successfully commercialize or partner any of its product candidates, it will be unable to generate product revenue or achieve profitability. ​ Significant Accounting Policies ​ There have been no material changes to the Company’s significant accounting policies during the three months ended March 31, 2026 from those discussed in the Company’s Annual Report on Form 10-K filed with the SEC on March 12, 2026. Recent Accounting Pronouncements ​ In October 2023, the Financial Accounting Standards Board (the “FASB”) issued ASU 2023-06, Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative, which modifies the disclosure or presentation requirements related to variety of FASB Accounting Standard Codification topics. The effective date for each amendment will be the date on which the SEC’s removal of that related disclosure from Regulation S-X or Regulation S-K is effective. If by June 30, 2027, the SEC has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the associated amendment will be removed from the Codification and will not become effective for any entities. The Company is currently evaluating the effect of adopting this ASU. In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expense. This update requires entities to disaggregate operating expenses into specific categories, such as salaries and wages, depreciation, and amortization, to provide enhanced transparency into the nature and function of expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, with early adoption permitted. ASU 2024-03 may be applied retrospectively or prospectively. The Company is currently evaluating the impact of ASU 2024-03 on its financial statement presentation and disclosures.
