Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Summary of Significant Accounting Policies The significant accounting policies used in preparation of the condensed consolidated financial statements are described in the Company’s audited consolidated financial statements as of and for the year ended December 31, 2023 and the notes thereto, which are included in the Company’s Annual Report on Form 10-K. Basis of Presentation and Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated in consolidation. The Company’s condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). Any reference in these notes to applicable guidance is meant to refer to the authoritative accounting principles generally accepted in the United States as found in the Accounting Standard Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). Unaudited Interim Condensed Consolidated Financial Information The accompanying condensed consolidated financial statements as of September 30, 2024 and for the three and nine months ended September 30, 2024 and 2023 are unaudited. The financial data and other information contained in the notes hereto as of September 30, 2024 and for the three and nine months ended September 30, 2024 and 2023 are also unaudited. The condensed consolidated balance sheet data as of December 31, 2023 was derived from the Company’s audited consolidated financial statements included in the Company’s Annual Report on Form 10-K. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements, and in the opinion of management, reflect all adjustments, which include only normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of September 30, 2024 and the results of its operations and cash flows for the three and nine months ended September 30, 2024 and 2023. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements as of and for the year ended December 31, 2023, and the notes thereto, included in the Company’s Annual Report on Form 10-K. The results for the three and nine months ended September 30, 2024 and 2023 are not necessarily indicative of results to be expected for the full years, or any other interim periods, or any future year or period. Use of Estimates The preparation of the Company’s condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting period. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to accrued research and development expenses; stock-based compensation expense; the fair value determinations for instruments accounted for at fair value; the fair value of the contingent value right (“CVR”) (see Note 3); the incremental borrowing rate for determining lease liabilities and right-of-use assets; and income taxes. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it has concluded to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates as there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ materially from those estimates or assumptions. Concentration of Credit Risk and of Significant Suppliers Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, and marketable securities. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits and limits its exposure to cash risk by placing its cash with high credit quality accredited financial institutions. The Company has concluded that it is not subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships. The Company relies, and expects to continue to rely, on a small number of vendors to manufacture supplies and to process its product candidates for its development programs. These programs could be adversely affected by a significant interruption in the manufacturing process or supply chain. Comprehensive Income (Loss) Comprehensive income (loss) is the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss) includes net income (loss) and the change in accumulated other comprehensive income (loss) for the period. Accumulated other comprehensive income (loss) consisted of foreign currency translation adjustments and unrealized gains (losses) on available-for-sale marketable securities during the three and nine months ended September 30, 2024 and 2023. Marketable Securities The Company classifies its marketable securities as available-for-sale. All of the Company’s marketable securities are available to the Company for use in current operations. As a result, the Company classified all of these securities as current assets even though the stated maturity of some individual securities may be one year or more beyond the balance sheet date. Marketable securities are maintained by an investment manager and consist of U.S. government securities. Marketable securities are carried at fair value with the unrealized gains and losses included in accumulated other comprehensive income (loss) as a component of stockholders’ equity until realized. Any premium or discount arising at purchase is amortized and/or accreted to interest income and/or expense over the life of the underlying marketable security. Although available to be sold to meet operating needs or otherwise, securities are generally held through maturity. The cost of securities sold is determined on a specific identification basis, and realized gains and losses are included in other income (expense), net within the condensed consolidated statements of operations and comprehensive loss. The Company reviews its portfolio of available-for-sale securities, using both quantitative and qualitative factors, to determine if declines in fair value below cost have resulted from a credit loss or other factors. If the decline in fair value is due to credit loss factors, a loss is recognized. To date, the Company has not experienced any credit losses and does not expect it is exposed to any significant credit risk on these investments. Recently Issued Accounting Pronouncements Not Yet Adopted Other accounting standards that have been issued or proposed by the FASB or other standards-setting bodies that do not require adoption until a future date are not expected to have a material impact on the Company’s condensed consolidated financial statements upon adoption.

The results for the three and nine months ended September 30, 2024 and 2023 are not necessarily indicative of results to be expected for the full years, or any other interim periods, or any future year or period.

Use of Estimates

The preparation of the Company’s condensed consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of expenses during the reporting period. Significant estimates and assumptions reflected in these condensed consolidated financial statements include, but are not limited to accrued research and development expenses; stock-based compensation expense; the fair value determinations for instruments accounted for at fair value; the fair value of the contingent value right (“CVR”) (see Note 3); the incremental borrowing rate for determining lease liabilities and right-of-use assets; and income taxes. The Company bases its estimates on historical experience, known trends and other market-specific or other relevant factors that it has concluded to be reasonable under the circumstances. On an ongoing basis, management evaluates its estimates as there are changes in circumstances, facts and experience. Changes in estimates are recorded in the period in which they become known. Actual results may differ materially from those estimates or assumptions.

Concentration of Credit Risk and of Significant Suppliers

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents, and marketable securities. The Company maintains deposits in federally insured financial institutions in excess of federally insured limits and limits its exposure to cash risk by placing its cash with high credit quality accredited financial institutions. The Company has concluded that it is not subject to unusual credit risk beyond the normal credit risk associated with commercial banking relationships.

The Company relies, and expects to continue to rely, on a small number of vendors to manufacture supplies and to process its product candidates for its development programs. These programs could be adversely affected by a significant interruption in the manufacturing process or supply chain.

Comprehensive Income (Loss)

Comprehensive income (loss) is the change in equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss) includes net income (loss) and the change in accumulated other comprehensive income (loss) for the period. Accumulated other comprehensive income (loss) consisted of foreign currency translation adjustments and unrealized gains (losses) on available-for-sale marketable securities during the three and nine months ended September 30, 2024 and 2023.

Marketable Securities

The Company classifies its marketable securities as available-for-sale. All of the Company’s marketable securities are available to the Company for use in current operations. As a result, the Company classified all of these securities as current assets even though the stated maturity of some individual securities may be one year or more beyond the balance sheet date. Marketable securities are maintained by an investment manager and consist of U.S. government securities. Marketable securities are carried at fair value with the unrealized gains and losses included in accumulated other comprehensive income (loss) as a component of stockholders’ equity until realized. Any premium or discount arising at purchase is amortized and/or accreted to interest income and/or expense over the life of the underlying marketable security.

Although available to be sold to meet operating needs or otherwise, securities are generally held through maturity. The cost of securities sold is determined on a specific identification basis, and realized gains and losses are included in other income (expense), net within the condensed consolidated statements of operations and comprehensive loss.

The Company reviews its portfolio of available-for-sale securities, using both quantitative and qualitative factors, to determine if declines in fair value below cost have resulted from a credit loss or other factors.
