Analysis Summary

Cambium Networks Corporation (CMBM) received a Staff Determination Letter from the Nasdaq Listing Qualifications Staff on January 9, 2026, citing an additional basis for delisting its securities from The Nasdaq Global Market. The new deficiency stems from the company's failure to hold an annual meeting of shareholders within twelve months of its prior fiscal year-end, a direct violation of Nasdaq Listing Rule 5620(a). This notice adds to existing non-compliance issues for which the company is already subject to a compliance plan before the Nasdaq Hearings Panel.

Management intends to submit its perspective on this additional deficiency to the Hearings Panel by January 16, 2026. The company expresses an expectation to meet its existing compliance plan, which involves filing its delinquent periodic reports. Furthermore, Cambium Networks anticipates filing a proxy statement and conducting its annual meeting of shareholders during the quarter ending June 30, 2026, as part of its strategy to regain full compliance with Nasdaq Listing Rules. The Determination Letter currently has no immediate effect on the trading of CMBM's shares.

However, the company explicitly states that there can be no assurance of regaining compliance. Potential consequences of delisting are severe and include increased difficulty in buying or selling ordinary shares, a material decline in share price, impaired ability to raise capital, and the possible triggering of penalties or termination rights under existing agreements. This Form 8-K filing does not contain any financial performance data, revenue, earnings, or guidance, as it is solely focused on the Nasdaq listing compliance issue.
