Rhea-AI Filing Summary

Cambium Networks Corporation notified the SEC that it cannot timely file its Annual Report on Form 10-K for the fiscal year ended December 31, 2025 because an ongoing restatement is required for prior periods. The Audit Committee concluded that financial statements for the fiscal years ended December 31, 2022 and December 31, 2023 and certain 2023–2024 quarterly statements should be restated due to errors primarily related to variable consideration under ASC 606. The company lists as delinquent its Form 10-K for 2024 and Forms 10-Q for the quarters ended March 31, 2025, June 30, 2025 and September 30, 2025, and says the restatement and related audit remain ongoing. The company anticipates its annual reports will include disclosures about substantial doubt regarding its ability to continue as a going concern and expects to issue full financial results when the reporting and audit process is completed.

Positive

  • None.

Negative

  • The Audit Committee concluded that audited financials for 2022 and 2023 and several quarterly statements require restatement, undermining prior-period reliability.
  • The company anticipates disclosures of substantial doubt about its ability to continue as a going concern in its upcoming annual reports.

Insights

Restatement for ASC 606 variable consideration drives the delay; audit and disclosure risks are elevated.

The Audit Committee concluded errors tied to variable consideration (sales returns, customer rebates) require restating 2022 and 2023 audited statements and multiple 2023–2024 quarterly periods. This means prior-period revenue recognition estimates are unreliable until the restatement and re-audit are complete.

Completion depends on remediation of internal controls, completion of revised accounting estimates, and the external audit. The company flags substantial doubt about going concern in advance of filing; the timing of finalized filings is governed by the audit schedule and remaining corrections.

Delinquent periodic reports and a going-concern disclosure raise capital and covenant considerations.

The filing lists the 2024 Form 10-K and 2025 quarterly 10-Qs as delinquent and anticipates going-concern disclosures in forthcoming annual reports. These are material governance events that can affect lender covenants, counterparty confidence, and access to capital until resolved.

Stakeholders should watch for the restated financials, auditor opinion, and any borrowing-covenant waivers or amendments disclosed in subsequent filings.

ASC 606 financial
"errors primarily related to variable consideration, including the estimates"
A U.S. accounting standard that sets consistent rules for when and how companies record revenue from contracts with customers, focusing on the transfer of promised goods or services. It matters to investors because it affects the timing and amount of reported sales and profit—like deciding whether a contractor can count payment when a job starts, progresses, or finishes—so it improves comparability and helps assess a company's true economic performance.
variable consideration financial
"primarily related to variable consideration, including the estimates for sales returns"
restatement regulatory
"should be restated and should no longer be relied upon"
A restatement is a company’s formal correction of previously released financial reports when errors or omissions are discovered, similar to fixing a report card after finding mistakes in the scores. It matters to investors because it can change past performance figures, alter valuation or earnings trends, and signal weaknesses in accounting controls or management oversight, which may affect confidence and the stock’s perceived risk.
going concern financial
"disclosures around substantial doubt regarding the Company's ability to continue as a going concern"
A going concern is a business that is expected to continue its operations and meet its obligations for the foreseeable future, rather than shutting down or selling off assets. This assumption matters to investors because it indicates stability and ongoing profitability, making the business a more reliable investment. Think of it as believing a restaurant will stay open and serve customers, rather than closing down suddenly.
Rule 12b-25 regulatory
"If the subject report could not be filed without unreasonable effort or expense"
Rule 12b-25 is an SEC filing provision that lets a company notify regulators and the public that it cannot file a required periodic report (like a quarterly or annual report) on time and explains the reason for the delay. For investors, the notice is a formal heads-up that financial information will arrive late—similar to a company calling to say it will be late turning in homework—so it signals increased uncertainty and may affect trading and risk assessments until the filing is available.

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 Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the “2025 Form 10-K”) by the prescribed filing due date.

As disclosed on August 11, 2025, on the Current Report on Form 8-K, 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 and (ii) the unaudited condensed consolidated 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 Reports on Form 10-Q for the periods ended March 31, 2025, June 30, 2025 and September 30, 2025 (together with the Annual Report on Form 10-K for the year ended December 31, 2025, the “Delinquent Reports”), and because the restatement process remains ongoing, the Company is unable to file the 2025 Form 10-K at this time. The Company continues to work diligently towards completing the restatement and filing the Delinquent Reports as soon as practicable.

The Company expects to issue its full financial results for the fiscal year ended December 31, 2025 when the financial reporting process along with the review of the results and the related audit are completed.

FAQ

Why did Cambium Networks (CMBM) file an NT 10-K delaying the 2025 Form 10-K?

Because the company is completing a restatement of prior-period financials. The Audit Committee found errors primarily related to variable consideration under ASC 606 that require restating 2022–2023 audited statements and multiple 2023–2024 quarterly reports, so filings are delayed pending the re-audit.

Which reports are listed as delinquent in the NT 10-K for CMBM?

The delinquent filings include the 2024 Form 10-K and 2025 quarterly 10-Qs. Specifically, the company identified the Form 10-K for year ended December 31, 2024 and Forms 10-Q for March 31, June 30 and September 30, 2025 as not yet filed.

What accounting issue triggered Cambium’s restatement?

Errors related to variable consideration under ASC 606. The company cited estimates for sales returns and customer rebates as the primary cause requiring correction and restatement of affected periods.
