Cambium Networks Corp filings document the company’s networking-solutions business, ordinary-share capital structure, operating and financial updates, and public-company reporting status. Recent 8-K disclosures cover results of operations, commercial activity, executive finance leadership changes, shareholder voting and capital-structure matters, and Nasdaq listing-rule communications.
The company’s SEC record also includes Form 12b-25 notices for delayed 10-K and 10-Q reports, restatement-related reporting issues, and material-event filings on minimum bid price compliance, periodic filing compliance, delisting determinations and OTC trading-risk disclosures.
Cambium Networks Corporation notified the SEC that it could not file its Quarterly Report on Form 10-Q for the period ended March 31, 2026 by the prescribed due date and expects to file within the five-day extension provided by Rule 12b-25.
The company says it prioritized completing recent annual and quarterly filings and now is allocating resources to finish the March 31, 2026 Form 10-Q. The filing estimates total revenues of approximately $44.5 million for the quarter, versus $33.7 million for the same period in 2025.
Cambium Networks Corporation’s latest annual report highlights severe financial and listing challenges alongside its wireless broadband and enterprise networking business overview. The company’s ordinary shares were suspended from Nasdaq on March 27, 2026 and now trade on the OTC Expert Market under the symbol CMBMF after a Nasdaq hearings panel issued a delisting determination.
Cambium discloses repeated violations of Nasdaq listing rules, ongoing appeals, and warns there is substantial doubt about its ability to continue as a going concern. It is in default under its secured Credit Agreement after failing financial covenants and could face acceleration of debt secured by substantially all assets. Multiple material weaknesses in internal control over financial reporting led to delinquent SEC filings and increased compliance risk.
Against this backdrop, Cambium describes a global business providing fixed wireless, fiber, Wi‑Fi, switching and security gateway solutions managed through its ONE Network and cnMaestro platforms, serving service providers, enterprises, industrial users and governments.
Cambium Networks reported weaker results and serious financial stress for the quarter ended September 30, 2025. Quarterly revenue was $43.0 million, down from $44.7 million a year earlier, with a net loss of $8.5 million versus $34.5 million after prior-year impairments. For the first nine months of 2025, revenue fell to $116.1 million from $137.0 million, and net loss narrowed to $29.7 million from $67.2 million.
Cash dropped to $9.7 million from $34.9 million at December 31, 2024, while total debt remained high at $66.4 million, all classified as current. The company is in default on key covenants under its Bank of America credit facilities and stopped paying required principal and interest in June 2025, giving the lender the right to demand immediate repayment. Management concluded that these issues create substantial doubt about Cambium’s ability to continue as a going concern.
The balance sheet shows a shareholders’ deficit of $28.3 million, reflecting accumulated losses and prior asset impairments. Cambium also restated its 2024 interim financials for errors in areas such as variable consideration, credit losses, inventory, taxes, and long-lived asset impairments. In March 2026, its ordinary shares were delisted from Nasdaq and began trading on the OTC Experts Market under the symbol CMBMF.
Cambium Networks Corporation reported continued losses, liquidity pressure, and covenant violations in its latest quarter. For the three months ended June 30, 2025, revenue fell to $39.4 million from $45.2 million a year earlier, with a quarterly net loss of $9.1 million. For the first half of 2025, revenue was $73.1 million versus $92.3 million in 2024, and the net loss narrowed to $21.1 million from $32.7 million.
Cash declined to $15.8 million at June 30, 2025 from $34.9 million at year-end 2024, while total debt of $66.3 million under a term loan and revolving credit facility is classified as current due to ongoing covenant defaults. The company has stopped paying scheduled principal and interest and faces an additional 2% default interest margin.
Management states that failure to obtain waivers or refinance, combined with debt maturing on November 17, 2026, raises substantial doubt about Cambium’s ability to continue as a going concern. Shareholders’ deficit widened to $20.8 million. Subsequent to the period, Cambium’s shares were delisted from Nasdaq and moved to trading on the OTC Expert Market under the symbol CMBMF.
Cambium Networks Corporation reported a weak first quarter of 2025 with serious liquidity concerns. Revenue fell to $33.7 million from $47.1 million a year earlier, a 28.3% decline, as demand softened across fixed wireless and enterprise networking products. Despite lower sales, gross profit edged up to $14.6 million, lifting gross margin to 43.3% as product mix and cost actions improved profitability per unit.
Total operating expenses dropped to $24.2 million, narrowing the operating loss to $9.6 million from $15.6 million. Net loss improved to $12.0 million, or $0.42 per share, compared with a restated loss of $18.4 million, or $0.66 per share, in the prior-year quarter.
Cash declined to $27.8 million as of March 31, 2025, while total debt of about $67.0 million under a term loan and revolving credit facility is classified as current because Cambium is in violation of key financial covenants. The company has also stopped making certain debt payments since June 2025, giving its lender the right to demand immediate repayment. Management states there is substantial doubt about Cambium’s ability to continue as a going concern.
The balance sheet shows total liabilities of $172.4 million and a shareholders’ deficit of $13.1 million, reflecting cumulative losses and impairments. Cambium is cutting costs, reducing capital spending and pursuing financing or asset sales, but there is no assurance these efforts will succeed. Separately, the company’s ordinary shares have been delisted from The Nasdaq Global Market after it failed to meet minimum bid price, timely filing, and annual meeting requirements, and now trade on the OTC Expert Market under the symbol CMBMF.
Cambium Networks Corp Senior VP of Products Vivek Vibhu reported a small, compensation-related share adjustment. On a Form 4, he recorded a tax-withholding disposition of 1,030 Ordinary Shares at $0.10 per share, used to cover tax obligations. After this non-market transaction, he directly holds 114,459 Ordinary Shares, so the change is minor relative to his overall position.
Cambium Networks Corporation filed a comprehensive 2024 annual report that also restates its 2023 audited financials and multiple 2023–2024 quarters after identifying material errors tied to internal control weaknesses. The company cites issues in revenue recognition, variable consideration, credit losses, inventory, impairment timing and tax valuation allowances.
Management and the audit committee concluded additional material weaknesses existed in internal control over financial reporting for 2023 and 2024, and Cambium became delinquent in SEC filings. The report notes substantial doubt about its ability to continue as a going concern and details ongoing non‑compliance with credit facility covenants and Nasdaq listing requirements that led to delisting and trading moving to the OTC Expert Market under “CMBMF.”
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.
Cambium Networks Corporation filed an amended report to correct how it described future trading of its ordinary shares following a Nasdaq delisting decision. The company now states that trading is expected to move first to the OTC Pink Limited tier and then to the Expert Market under the symbol CMBM.
Nasdaq’s Hearings Panel decided on March 25, 2026 to delist Cambium’s ordinary shares for failure to comply with milestones in a prior decision, and trading on Nasdaq will be suspended at the open on March 27, 2026. Cambium is considering whether to appeal to the Nasdaq Listing and Hearing Review Council, but any appeal would not prevent the suspension. The company warns that trading on OTC Pink and the Expert Market may materially reduce share price and volume and make it harder for shareholders to buy or sell shares.
Cambium Networks Corporation reported that the Nasdaq Hearings Panel has decided to delist its ordinary shares from The Nasdaq Stock Market after the company failed to comply with milestones in a prior panel decision. Trading on Nasdaq will be suspended at the open on March 27, 2026. Cambium expects its shares to be quoted on OTC Markets, initially on the OTC Pink Limited tier and then the Expert Market, which the company warns may materially reduce trading price, liquidity, transparency, and increase volatility. The company is considering whether to appeal the delisting decision to the Nasdaq Listing and Hearing Review Council, but any appeal would not prevent the Nasdaq trading suspension.
