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.
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.
The company is already operating under a compliance plan related to delinquent periodic reports and expects to meet that plan, then file a proxy statement and hold its annual meeting during the quarter ended June 30, 2026. Cambium cautions that there is no assurance it will regain compliance with Nasdaq listing rules, and notes that a delisting could make trading its shares more difficult, pressure the share price, hinder capital-raising efforts, and potentially trigger penalties or termination rights in existing agreements.
Cambium Networks Corporation reported that Nasdaq has confirmed it is now in compliance with the Minimum Bid Price Rule, but the company remains out of compliance with the Periodic Filing Rule. A Nasdaq Hearings Panel will retain jurisdiction over the company until April 8, 2026, and Cambium will be subject to a mandatory panel monitor until December 12, 2026. If the company falls out of compliance with the Minimum Bid Price Rule again during this monitoring period, Nasdaq staff may issue a delisting determination, subject to a new hearing.
The company also announced an executive transition. Mitchell Cohen has been appointed Interim Chief Financial Officer and principal financial officer, effective immediately, while John Waldron has stepped down as acting chief financial officer and will remain with Cambium as a senior financial advisor. The company noted that Mr. Cohen has extensive public company and transactional finance experience, and disclosed there are no related-party relationships or transactions with him under applicable SEC rules.
Cambium Networks Corporation filed a Form 8-K to report that it issued a press release on November 18, 2025 providing an update on recent financial and commercial activity. The company notes that the press release includes forward-looking statements along with cautionary language about factors that could cause actual results to differ. The press release is furnished as Exhibit 99.1 and, together with the related disclosure, is being treated as "furnished" rather than "filed" under the securities laws, which limits potential liability and incorporation by reference into other filings.
Cambium Networks (CMBM) reported a Nasdaq staff determination that its ordinary shares are subject to delisting from the Nasdaq Global Market. The notice follows failure to meet the $1.00 minimum bid price for 30 consecutive business days and not regaining compliance by October 7, 2025 under Listing Rule 5810(c)(3)(A). The company also remains noncompliant with filing requirements for its 2024 Form 10-K and Forms 10-Q for the quarters ended March 31, 2025 and June 30, 2025, which is a separate basis for delisting under Listing Rule 5810(c)(2).
The company intends to request a hearing before a Nasdaq Hearings Panel regarding both the bid price and delinquent filings. A hearing request will automatically stay any suspension for 15 calendar days, and the panel will rule on an extended stay within 15 days following the hearing-request deadline. The letter has no immediate effect on trading. A press release was issued on October 16, 2025.
Cambium Networks Corporation reported that it received a delinquency notice from Nasdaq on August 25, 2025 because it did not timely file its Quarterly Report on Form 10-Q for the period ended June 30, 2025. Nasdaq’s notice also references the company’s previously delinquent Annual Report on Form 10-K for the year ended December 31, 2024 and Quarterly Report on Form 10-Q for the three months ended March 31, 2025. The company has until October 13, 2025 to file all of these delinquent reports, and Nasdaq has requested an updated plan to regain compliance, including plans to file the June 30, 2025 Form 10-Q by September 9, 2025.
Cambium Networks Corporation filed an update covering recent business activity and a key finance leadership change. The company furnished a press release dated August 26, 2025 as Exhibit 99.1 that provides an update on recent commercial activity and includes forward-looking statements with related cautionary language.
The company also disclosed that Chief Financial Officer and principal financial officer Jacob Sayer will leave his role effective September 5, 2025 to pursue other opportunities. The resignation is described as not resulting from any disagreement over operations, policies, or practices. Cambium Networks appointed John Waldron as Acting Chief Financial Officer and principal financial officer effective August 26, 2025, with no change to his existing compensation.
Cambium Networks announced that its Audit Committee concluded previously issued financial statements for the fiscal years ended December 31, 2022 and 2023 and certain interim periods in 2023 and 2024 are not reliable and should be restated due to material errors. The errors relate primarily to variable consideration under ASC 606, including estimates for sales returns and customer rebates, and the company believes its estimation models did not sufficiently use information available at each reporting date nor apply adequate retrospective analysis. The company did not file its annual report for fiscal 2024 or its Q1 2025 report by the required dates and expects it cannot timely file the Q2 2025 report. Its disclosure controls and internal control over financial reporting were determined to be ineffective as of September 30, 2024 and remain ineffective. Management review is ongoing and additional material errors or control weaknesses may be identified; the company is working with its current auditor, Grant Thornton LLP, and has informed its prior auditor, KPMG LLP.
