Item 4.01 Changes in Registrant’s Certifying Accountant.

(a) Dismissal of Former Independent Registered Public Accounting Firm

The Audit Committee (the “Committee”) of the Board of Directors of Cambium Networks Corporation (the “Company”) recently conducted a competitive selection process to determine the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024. The Committee invited several international public accounting firms to participate in this process, including KPMG LLP (“KPMG”), the Company’s independent registered public accounting firm for the fiscal year ended December 31, 2023. As a result of this process, on April 5, 2024, the Committee approved the appointment of Grant Thornton LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024. KPMG was dismissed as the Company’s independent registered public accounting firm on April 5, 2024.

The audit reports of KPMG on the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2022 and 2023 did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2022 and 2023, and the subsequent interim period through April 5, 2024, there were no disagreements (within the meaning of Item 304(a)(1)(iv)) with KPMG on any matters of accounting principles or practices, financial statement disclosure or auditing scope and procedures, which if not resolved to the satisfaction of KPMG, would have caused KPMG to make reference to the subject matter of such disagreement in their report on the Company’s consolidated financial statements for such year. There were no reportable events (as that term is described in Item 304(a)(1)(v) of Regulation S-K) during the two fiscal years ended December 31, 2022 and 2023, and the subsequent interim period through April 5, 2024, except that KPMG advised the Company of the following material weaknesses: the Company's control environment was ineffective in identifying changes in risk and designing internal controls that are responsive to risks, resulting in certain process-level controls related to the determination of inventory excess and obsolescence reserve and recoverability of deferred tax assets not being designed effectively.

The Company has provided a copy of the foregoing disclosures to KPMG and requested that KPMG furnish it with a letter addressed to the Securities and Exchange Commission stating whether KPMG agrees with the above statements. A copy of KPMG’s letter, dated April 11, 2024, is filed as Exhibit 16.1 to this Form 8-K.

(b) Engagement of New Independent Registered Public Accounting Firm.

On April 5, 2024, the Audit Committee of the Board of Directors approved the appointment of Grant Thornton as the Company’s independent registered public accounting firm for the year ending December 31, 2024.

During the two most recent fiscal years and through the date of this Current Report, the Company has not consulted with Grant Thornton with respect to (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that would have been rendered on the Company’s consolidated financial statements, and no written report or oral advice was provided to the Company by Grant Thornton that Grant Thornton concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue, or (ii) or any other matters that was subject of a disagreement as defined in Item 304(a)(1)(iv) of Regulation S-K or a reportable event as defined in Item 304(a)(1)(v) of Regulation S-K.
