Insights

Financial Analyst

TL;DR: Restatement of audited years and multiple quarters creates material uncertainty and likely negative investor impact.

The Audit Committees conclusion that audited consolidated financials for 2022 and 2023 and multiple quarterly reports must be restated for ASC 606 variable-consideration errors is a material event. The companys inability to file its Annual Report for year ended December 31, 2024 and subsequent quarterly reports increases uncertainty. The filing explicitly notes the restatement may be costly and time-consuming and that prior disclosures for the Non-Reliance Periods should no longer be relied upon, which can affect comparability, covenant metrics, financing arrangements, and investor confidence.

Corporate Governance Expert

TL;DR: Audit Committee-led restatement and cited internal-control issues signal governance and control deficiencies requiring remediation.

The notification shows direct Audit Committee involvement and an ongoing restatement process tied to errors in revenue recognition estimates. The filing references material weaknesses in internal control over financial reporting as of December 31, 2024 and indicates prior public communications covering the Non-Reliance Periods are unreliable. This raises concerns about oversight, remediation timelines, and managements ability to restore reliable financial reporting promptly.

PART III — NARRATIVE

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

Cambium Networks Corporation (the “Company”) has determined that it is unable to file, without unreasonable effort or expense, its Quarterly Report on Form 10-Q for the period ended June 30, 2025 (the “Second Quarter 2025 Report”) by the prescribed filing due date.

As disclosed on August 11, 2025, on the Current Report on Form 8-K, the Audit Committee (the “Audit Committee”) of the Board of Directors of the Company, after discussion with management, concluded that the Company’s previously issued financial statements and related disclosures for (i) the audited consolidated financial statements for the fiscal years ended December 31, 2022 and December 31, 2023 included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “Audited Financial Statements”) and (ii) the unaudited condensed consolidated financial statements (the “Unaudited Financial Statements”) included in the Company’s Quarterly Reports on Form 10-Q for the periods ended March 31, 2023, June 30, 2023, September 30, 2023, March 31, 2024, June 30, 2024 and September 30, 2024 (collectively, the “Non-Reliance Periods”) should be restated and should no longer be relied upon due to errors in such financial statements primarily related to variable consideration, including the estimates for sales returns and customer rebates, under Accounting Standards Codification 606, Revenue from Contracts with Customers. In addition, investors should no longer rely upon any press releases, earnings releases, investor presentations and other financial information or other communication that cover any period during the Non-Reliance Periods.

As the Company has not yet filed its Annual Report on Form 10-K for the year ended December 31, 2024 or its Quarterly Report on Form 10-Q for the three months ended March 31, 2025 (together with the Second Quarter 2025 Report, the “Delinquent Reports”), and because the restatement process remains ongoing, the Company is unable to file the Second Quarter 2025 Report at this time. The Company continues to work diligently towards completing the restatement and filing the Delinquent Reports as soon as practicable. The Company anticipates that its Annual Report on Form 10-K for the fiscal year ended December 31, 2024 will include disclosures around the substantial doubt regarding the Company’s ability to continue as a going concern.
