Summary of Significant Accounting Policies	2. Summary of Significant Accounting Policies Basis of Presentation The accompanying condensed consolidated financial statements and the related disclosures are unaudited and have been prepared in accordance with accounting principles generally accepted in the U.S. Additionally, certain information and footnote disclosures normally included in the Company’s annual financial statements have been condensed or omitted. Accordingly, these interim condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the Securities and Exchange Commission (“SEC”) on February 16, 2024 (the “2023 Annual Report on Form 10-K”). The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, reflect all normal recurring adjustments considered necessary for a fair statement of the Company’s financial position as of September 30, 2024, and the results of its operations for the three and nine months ended September 30, 2024 and 2023, its statements of stockholders’ equity (deficit) for the three and nine months ended September 30, 2024 and 2023, and its cash flows for the nine months ended September 30, 2024 and 2023. The results of operations for the three and nine months ended September 30, 2024 and 2023 are not necessarily indicative of the results that may be expected for the full year or any other subsequent interim period. Principles of Consolidation The accompanying condensed consolidated financial statements as of September 30, 2024 include the accounts of Ironwood and its wholly-owned subsidiaries, Ironwood Pharmaceuticals Securities Corporation, Ironwood Pharmaceuticals GmbH, VectivBio AG, GlyPharma Therapeutic Inc. (“GlyPharma”), and VectivBio US, Inc. All intercompany transactions and balances are eliminated in consolidation. For consolidated entities in which the Company owns less than 100% of the outstanding shares, the Company records net income (loss) and comprehensive income (loss) attributable to noncontrolling interests in its consolidated statements of income (loss) and comprehensive income (loss), respectively, equal to the percentage of the common stock ownership interest retained in such entities by the noncontrolling parties. The Company reports noncontrolling interests in consolidated entities as a component of equity separate from the Company’s equity. Use of Estimates The preparation of condensed consolidated financial statements in accordance with U.S. generally accepted accounting principles requires the Company’s management to make estimates and judgments that may 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 amounts of revenues and expenses during the reported periods. On an ongoing basis, the Company’s management evaluates its estimates, judgments and methodologies. Estimates and assumptions in the condensed consolidated financial statements include those related to fair value of assets acquired and liabilities assumed in acquisitions; revenue recognition; accounts receivable; useful lives of long-lived assets; impairment of long-lived assets, including goodwill; valuation procedures for right-of-use assets and operating lease liabilities; income taxes, including uncertain tax positions and the valuation allowance for deferred tax assets; research and development expenses; contingencies; defined benefit pension liabilities; and share-based compensation. The Company bases its estimates on historical experience 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 materially from these estimates under different assumptions or conditions. Changes in estimates are reflected in reported results in the period in which they become known. Summary of Significant Accounting Policies The Company’s significant accounting policies are described in Note 2, Summary of Significant Accounting Policies, in the 2023 Annual Report on Form 10-K. During the three and nine months ended September 30, 2024, the Company did not adopt any additional significant accounting policies. New 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. The Company did not adopt any new accounting pronouncements during the three and nine months ended September 30, 2024 that had a material effect on its condensed consolidated financial statements. In October 2023, the FASB issued Accounting Standards Update (“ASU”) No. 2023-06, Disclosure Improvements: Codification Amendment in Response to the SEC’s Disclosure Update and Simplification Initiative (“ASU 2023-06”). The guidance in ASU 2023-06 aligns the disclosure and presentation requirements in the FASB Accounting Standards Codification with the SEC’s regulations. The effective date for each amendment will be the date on which the SEC's removal of the related disclosure requirement from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. Any amendments not removed by the SEC by June 30, 2027 will not become effective. The amendments adopted in ASU 2023-06 will be applied prospectively. The Company is currently evaluating the impact that the adoption of ASU 2023-06 may have on its disclosures in its condensed consolidated financial statements. In November 2023, the FASB issued ASU No. 2023-07, Segment Reporting (Topic 280) (“ASU 2023-07”). The guidance in ASU 2023-07 expands prior reportable segment disclosure requirements by requiring entities to disclose significant segment expenses that are regularly provided to the Chief Operating Decision Maker (“CODM”) and details of how the CODM uses financial reporting to assess their segment’s performance. The guidance is 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 ASU is required to be applied retrospectively upon adoption. The Company is currently evaluating the impact that the adoption of ASU 2023-07 may have on its condensed consolidated financial statements. In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (“ASU 2023-09”). The guidance in ASU 2023-09 improves the transparency of annual income tax disclosures by requiring greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The standard is effective for fiscal years beginning after December 15, 2024, with early adoption permitted. Upon adoption, ASU 2023-09 may be applied prospectively or retrospectively. The Company is currently evaluating the impact that the adoption of ASU 2023-09 may have on its disclosures in its annual consolidated financial statements. In November 2024, the FASB issued ASU No. 2024-03, Disaggregation of Income Statement Expenses (“ASU 2024-03”). The guidance in ASU 2024-03 requires new financial statement disclosures in tabular format, disaggregating information about prescribed categories underlying any relevant income statement expense captions. The standard is effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. Upon adoption, ASU 2024-03 may be applied prospectively or retrospectively. The Company is currently evaluating the impact that the adoption of ASU 2024-03 may have on its disclosures in its condensed consolidated financial statements. Other recent accounting pronouncements issued, but not yet effective, are not expected to be applicable to the Company or have a material effect on the condensed consolidated financial statements upon future adoption.
