Item 4.01 Changes in Registrant’s Certifying Accountant.
(a) Dismissal of Independent Registered Public Accounting Firm
On July 3, 2025, the Audit Committee (the “Audit Committee”) of the Board of Directors of Ironwood Pharmaceuticals, Inc. (the “Company”) dismissed Ernst & Young LLP (“EY”) as the Company’s independent registered public accounting firm. The Audit Committee made its decision after soliciting and reviewing competitive proposals from independent registered public accounting firms, including EY. The Company notified EY of its decision on July 3, 2025.
The reports of EY on the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2024 and December 31, 2023 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles.
During the Company’s fiscal years ended December 31, 2024 and December 31, 2023, and the subsequent interim period through July 3, 2025, there were no (i) “disagreements” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) between the Company and EY on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures which, if not resolved to EY’s satisfaction, would have caused EY to make reference to the subject matter of such disagreement in its reports on the Company’s consolidated financial statements for the relevant year, or (ii) “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K), except as described below.
EY’s report on the Company’s internal control over financial reporting as of December 31, 2024, contained an adverse opinion, specifically, that the Company did not maintain effective internal control over financial reporting as of December 31, 2024, due to the effect of certain material weaknesses described in such report. The material weaknesses in the Company’s internal control over financial reporting related to certain control deficiencies in the design and implementation of the Company’s internal control over financial reporting related to entity level controls, information technology general controls, financial statement close process controls, and expenditures controls, as previously reported in “Part II, Item 9A – Controls and Procedures” of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the Securities and Exchange Commission (the “SEC”) on March 31, 2025. Such material weaknesses did not result in a restatement of previously issued annual consolidated financial statements or condensed interim consolidated financial statements. These material weaknesses were discussed among the Audit Committee and EY. The Company has authorized EY to respond fully to the inquiries of KPMG LLP (“KPMG”), the successor independent registered public accounting firm, concerning the subject matter of these material weaknesses.
The Company has provided EY with the disclosures it is making in this Current Report on Form 8-K and requested that it furnish a letter addressed to the SEC stating whether or not it agrees with the above statements and, if not, stating the respects in which it does not agree. A copy of EY’s letter, dated July 10, 2025, provided in response to the Company’s request, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
(b) Appointment of New Independent Registered Public Accounting Firm
On July 3, 2025, the Audit Committee approved the appointment of KPMG to serve as the Company’s new independent registered public accounting firm, effective immediately, for the fiscal year ending December 31, 2025. During the fiscal years ended December 31, 2024 and December 31, 2023, and the subsequent interim period through July 3, 2025, neither the Company, nor anyone on its behalf, consulted KPMG regarding either (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered with respect to the consolidated financial statements of the Company, and no written report or oral advice was provided to the Company by KPMG that KPMG concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue; or (ii) any matter that was the subject of a “disagreement” (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to Item 304 of Regulation S-K) or a “reportable event” (as defined in Item 304(a)(1)(v) of Regulation S-K).
