• Cambium Networks Corporation (CMBM) received an additional staff determination letter from Nasdaq on November 25, 2025, notifying it of non-compliance with Listing Rule 5250(c)(1) (the Filing Rule).

• This Q3 2025 delinquency serves as an additional basis for delisting the company's Ordinary Shares from The Nasdaq Global Market.

• Nasdaq had previously granted an extension until October 13, 2025, for the company to regain compliance.
• On November 11, 2025, the company presented its plan of compliance to the Nasdaq Hearings Panel and requested a continued stay of delisting.
• The Hearings Panel is currently reviewing the company's extended stay request and will consider the Q3 2025 Delinquent Filing in its decision.
• The company issued a press release on December 1, 2025, announcing the receipt of the Staff Determination Letter.
