Accounting Policies [Abstract] |
Basis of Presentation and Summary of Significant Accounting Policies | 2. Basis of Presentation and Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements include the accounts of Mural Oncology plc and its wholly-owned subsidiaries. For the periods prior to the Separation, the accompanying unaudited condensed consolidated financial statements of the Company have been prepared on a standalone basis and are derived from the Former Parent’s consolidated financial statements and accounting records. All intercompany transactions and accounts within the Company have been eliminated. The unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and, for the periods prior to the Separation, reflect the historical results of operations, financial position and cash flows of Mural, as included in the consolidated financial statements of the Former Parent and using the Former Parent’s historical accounting policies. For the periods prior to the Separation, these unaudited condensed consolidated financial statements do not purport to reflect what the Company’s results of operations, financial position or cash flows would have been had the Company operated as a standalone public company prior to the Separation, nor are they necessarily indicative of the Company’s future results of operations, financial position, or cash flows. As the Company’s operations were not historically held by a single legal entity or separate legal entities, net parent investment is shown in lieu of stockholders’ equity in the historical combined financial statements for the periods prior to the Separation. Net parent investment represents the cumulative investment by the Former Parent in the Company through the dates presented, inclusive of operating results. All transactions between the Company and the Former Parent are considered to be effectively settled in the unaudited condensed consolidated financial statements at the time the transaction is recorded. The effects of the settlement of these transactions between the Company and the Former Parent are reflected in the unaudited condensed consolidated statements of cash flows as “Net transfers from Former Parent” within financing activities and in the unaudited condensed consolidated statements of equity (deficit) as “Net parent investment.” Historically, the Company was dependent upon the Former Parent for all of its working capital and financing requirements, as the Former Parent used a centralized approach to cash management and financing its operations. There were no cash amounts specifically attributable to the Company for the historical periods presented prior to the Separation. Financing transactions prior to the Separation related to the Former Parent are accounted for as a financing activity on the accompanying unaudited condensed consolidated statements of cash flows through the date of the Separation. In connection with the Separation, certain assets and liabilities that were included on the consolidated balance sheet prior to the Separation were retained by the Former Parent and were therefore adjusted through net parent investment in the Company’s consolidated financial statements. The unaudited condensed consolidated financial statements of the Company include, for the periods prior to the Separation, the assets, liabilities, and expenses of the Former Parent that management has determined are specifically identifiable to the Company, such as those related to direct internal and external R&D activities as well as leases and fixed assets specifically identifiable to the oncology business. Based on the nature of the Company as a pre-revenue, development-stage biotechnology company, the unaudited condensed consolidated financial statements of the Company do not include any revenue or commercial expenses of the Former Parent. The unaudited condensed consolidated financial statements of the Company also include, for the periods prior to the Separation, an allocation of costs that were not directly attributable to the operations of the Company, including the costs of general and administrative support functions that were provided by the Former Parent, such as senior management, information technology, legal, accounting and finance, human resources, facility, and other corporate services. In addition, the Company’s unaudited condensed consolidated financial statements include, for the periods prior to the Separation, an allocation of certain R&D costs not directly attributable to individual programs. These costs have been allocated to the Company for the purposes of preparing the unaudited condensed consolidated financial statements based on proportional cost allocation methods using headcount, square footage or proportional hours worked supporting the Company and other organizational activities, as applicable, which are considered to be reasonable reflections of the utilization of services provided or benefit received by the Company during the periods presented. Management considers that such allocations have been made on a reasonable basis; however, these allocations may not necessarily be indicative of the costs that would have been incurred if the Company had operated on a standalone basis for the periods presented and, therefore, may not reflect the Company’s results of operations, financial position, and cash flows had the Company operated as a standalone entity during the periods presented. See Note 12, Related Parties, for additional information regarding related-party transactions with the Former Parent. The Company expects to incur additional operating expenses to operate as an independent publicly traded company, including various corporate functions, incremental information technology-related costs and incremental costs to operate standalone accounting, legal and other administrative functions. These functions were provided to the Company prior to the Separation by the Former Parent and will continue under a transition services agreement with the Former Parent or will be performed using the Company’s own resources. Unaudited Interim Financial Information The accompanying condensed consolidated financial statements of the Company for the three months ended March 31, 2024 are unaudited and have been prepared on a basis substantially consistent with the audited financial statements for the year ended December 31, 2023. The condensed consolidated financial statements for the three months ended March 31, 2023 were derived from the Former Parent’s audited financial statements. The year-end condensed consolidated balance sheet data, which are presented for comparative purposes, were derived from audited financial statements but do not include all disclosures required by GAAP. In the opinion of management, the condensed consolidated financial statements include all adjustments of a normal recurring nature that are necessary to state fairly the results of operations for the reported periods. The financial data and other information disclosed in these notes related to the three months ended March 31, 2024 and 2023 are also unaudited. Certain information and footnote disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the SEC for interim financial statements. These unaudited interim condensed consolidated financial statements should be read in conjunction with the audited annual 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 for the fiscal year ended December 31, 2023 (the “Annual Report on Form 10-K”). The results for the three months ended March 31, 2024 are not necessarily indicative of results to be expected for the year ending December 31, 2024, any other interim periods, or any future year or period. Use of Estimates The preparation of the Company’s unaudited condensed consolidated financial statements in accordance with GAAP requires the Company to make estimates, judgments and assumptions that may affect the reported amounts of assets, liabilities and expenses and the related disclosure of contingent assets and liabilities. On an ongoing basis, the Company evaluates its estimates and judgments and methodologies, including but not limited to, those related to allocations of expenses, assets and liabilities from the Former Parent’s historical financials to the Company, the impairment of long-lived assets, and measurement of share-based compensation, leases, and income taxes including the valuation allowance for deferred tax assets. The Company bases its estimates on historical experience of the Former Parent and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results may differ from these estimates under different assumptions or conditions. Significant Accounting Policies The significant accounting policies used in preparation of these unaudited condensed consolidated financial statements as of and for the three months ended March 31, 2024 and 2023 are consistent with those discussed herein and in Note 2, Basis of Presentation and Summary of Significant Accounting Policies, in the “Notes to Consolidated Financial Statements” accompanying the Company’s Annual Report on Form 10-K. Recently Issued Accounting Pronouncements From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board (the “FASB”) or other standard-setting bodies that are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures (“ASU 280”). ASU 280 requires public entities to disclose significant segment expenses that are regularly provided to the chief operating decision maker and to disclose how reported measures of segment profit or loss are used in assessing segment performance and allocating resources. The amendments in ASU-280 are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the impact of the adoption of ASU-280 on its consolidated financial statements and related disclosures and does not expect the adoption of ASU-280 to have a material impact on the Company’s consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU-740”). ASU-740 requires public entities to provide enhanced disclosure of specific categories of reconciling items included in the rate reconciliation; disclosure of the nature, effect and underlying causes of each reconciling item in the rate reconciliation and the judgment used in the categorization of such items; and enhanced disclosures for income taxes paid. The amendments in this ASU are effective for fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is evaluating the impact of the adoption of ASU-740 on its consolidated financial statements and disclosures.
