Rhea-AI Filing Summary

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.

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.

Positive

None.

Negative

Nasdaq delinquency notice for multiple late filings: Cambium Networks is not in compliance with Nasdaq Listing Rule 5250(c)(1) due to missing its June 30, 2025 Form 10-Q, in addition to earlier delinquent 2024 Form 10-K and March 31, 2025 Form 10-Q, with a firm deadline to cure.

Insights

Cambium Networks faces Nasdaq noncompliance deadline tied to three late SEC reports.

Cambium Networks has been notified by Nasdaq that it is not in compliance with Listing Rule 5250(c)(1) because it has not filed its Form 10-Q for June 30, 2025. The notice also cites earlier missing filings: the Form 10-K for December 31, 2024 and Form 10-Q for March 31, 2025.

Nasdaq has given the company until October 13, 2025 to file all delinquent reports, and requested an updated compliance plan, including plans to file the June 30, 2025 Form 10-Q by September 9, 2025. This concentrates execution risk around the company’s ability to complete and file multiple reports within a defined window.

The situation centers on reporting timeliness rather than operating performance, but investors may focus on whether the company meets the specified filing dates and restores compliance with Nasdaq’s reporting rule.
