Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On November 25, 2025, Cambium Networks Corporation (the “Company”) received an additional staff determination letter (“Staff Determination Letter”) from the Listing Qualifications Department (the “Staff”) of the Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company it was not in compliance with Nasdaq’s continued listing standards as set forth in Listing Rule 5250(c)(1) (the “Filing Rule”), given the Company’s inability to timely file its Quarterly Report on Form 10-K for the period ended September 30, 2025 (“Q3 2025 Delinquent Filing” and together with the prior delinquent filings referenced below, the “Delinquent Filings”), and that this matter serves as an additional basis for delisting the Company’s Ordinary Shares from The Nasdaq Global Market.

As previously disclosed, the Company received deficiency letters from the Staff on April 16, 2025, May 22, 2025 and August 25, 2025 that the Company was not in compliance with the Filing Rule, since the Company had not yet filed its Annual Report on Form 10-K for the year ended December 31, 2024 and its Quarterly Reports on Forms 10-Q for the periods ended March 31, 2025, and June 30, 2025, respectively, with the U.S. Securities and Exchange Commission. The Staff had granted an extension of time until October 13, 2025 for the Company to regain compliance with the Filing Rule.

On November 11, 2025, the Company presented its plan of compliance before the Nasdaq Hearings Panel (the “Hearings Panel”) and requested a continued stay of its delisting pending achieving full compliance by filing the Delinquent Filings within the time requested under the plan of compliance. There can be no assurance that the Hearings Panel will grant any of the Company’s requests for additional time to gain compliance. As of the date of the filing of this Current Report on Form 8-K, the Company’s extended stay request remained under review by the Hearings Panel. Once the Hearings Panel makes a ruling on the extended stay, the Company intends to make a subsequent announcement. As the Company is already before the Hearings Panel, the Hearings Panel will consider the Q3 2025 Delinquent Filing in their decision regarding the Company’s continued listing on The Nasdaq Global Market.

As required under Listing Rule 5810(b), on December 1, 2025, the Company issued a press release announcing its receipt of the Staff Determination Letter. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
