Item 4.01 Changes in Registrant's Certifying Accountant.
On March 9, 2026, upon the completion of a comprehensive selection process, the Audit Committee of the Board of Directors of Upland Software, Inc. (the "Company") approved (1) the dismissal of Ernst & Young LLP ("EY") as the Company's independent registered public accounting firm, effective immediately, and (2) the appointment of KPMG LLP ("KPMG") as the Company's independent registered public accounting firm for the fiscal year ending December 31, 2026, and related interim periods, subject to the completion of KPMG's customary client acceptance procedures and the execution of an engagement letter. The Company informed EY of their dismissal on March 10, 2026.
The reports of EY on the consolidated financial statements of the Company as of and for the fiscal years ended December 31, 2025 and 2024 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.
In connection with the audits of the Company's consolidated financial statements for each of the fiscal years ended December 31, 2025 and 2024, and in the subsequent interim period through March 10, 2026, there were no disagreements between the Company and EY on any matters of accounting principles or practices, financial statement disclosure, or auditing scope or procedures which, if not resolved to the satisfaction of EY would have caused EY to make reference to the matter in their report.
The Company has requested EY to furnish it with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made herein. A copy of such letter dated March 13, 2026, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
During the fiscal years ended December 31, 2025 and 2024 and during the subsequent interim period through March 10, 2026, neither the Company nor anyone acting on its behalf consulted with 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 on the Company's consolidated financial statements and neither a written report nor oral advice was provided to the Company that KPMG concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing, or financial reporting issue, or (ii) any matter that was either the subject of a "disagreement" (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions) or a "reportable event" (as defined in Item 304(a)(1)(v) of Regulation S-K and the related instructions).
