Welcome to our dedicated page for Cambium Networks SEC filings (Ticker: CMBM), a comprehensive resource for investors and traders seeking official regulatory documents including 10-K annual reports, 10-Q quarterly earnings, 8-K material events, and insider trading forms.
The Cambium Networks Corporation (NASDAQ: CMBM) SEC filings page on Stock Titan provides access to the company’s regulatory disclosures as filed with the U.S. Securities and Exchange Commission. These documents include current reports on Form 8‑K, notifications of late filing on Form 12b‑25 (NT 10‑Q), and other periodic reports that outline key financial reporting issues, listing‑rule developments, and executive transitions.
Recent Form 8‑K filings describe Nasdaq listing matters, including notices related to the Minimum Bid Price Rule and the Periodic Filing Rule, as well as a decision by a Nasdaq Hearings Panel granting continued listing subject to specific conditions. These filings explain how bid‑price compliance was regained and how ongoing non‑compliance with timely periodic reporting is being addressed, along with panel monitoring requirements and potential consequences if deficiencies recur.
Other 8‑K reports and NT 10‑Q filings detail Cambium Networks’ financial restatement process. The Audit Committee concluded that certain previously issued audited and unaudited financial statements should be restated and should no longer be relied upon, primarily due to errors in estimating variable consideration such as sales returns and customer rebates under ASC 606. The company’s notifications of late filing explain delays in submitting its Annual Report on Form 10‑K for the year ended December 31, 2024 and several 2025 Form 10‑Q reports, and indicate that forthcoming filings are expected to include disclosures about substantial doubt regarding the company’s ability to continue as a going concern.
Cambium also uses 8‑K filings to report executive transitions in its finance organization, such as the departure of a chief financial officer, the appointment of an acting chief financial officer, and the later appointment of an interim chief financial officer and principal financial officer. These disclosures provide context on leadership changes during the period of financial restatement and Nasdaq compliance efforts.
On Stock Titan, these SEC filings are paired with AI‑powered summaries that highlight the main points of each document, helping readers quickly understand the nature of listing‑rule notices, restatement updates, late‑filing explanations, and executive changes. Users can review the full text of Forms 8‑K and NT 10‑Q while relying on concise AI explanations to navigate complex regulatory language and identify items most relevant to their analysis of CMBM.
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.

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.

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 on January 9, 2026 it received a Nasdaq staff determination letter noting an additional basis for delisting because the company did not hold an annual shareholder meeting within twelve months of its prior fiscal year end, as required by Nasdaq Listing Rule 5620(a). This new deficiency will be considered by a Nasdaq hearings panel that has asked the company to respond in writing by January 16, 2026, and the letter does not immediately affect the trading of Cambium’s ordinary shares on the Nasdaq Global Market.
