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 Corporation filed a notice that it will not be able to submit its Form 10-Q for the quarter ended September 30, 2025 on time. The delay stems from an ongoing restatement of its previously issued audited financials for 2022 and 2023 and unaudited quarterly results for multiple periods in 2023 and 2024 related to errors in revenue recognition, including estimates for sales returns and customer rebates under ASC 606.
The company has also yet to file its Form 10-K for 2024 and its Forms 10-Q for the quarters ended March 31, 2025 and June 30, 2025, which together with the latest quarter are described as delinquent reports. Cambium states it is working to complete the restatement and filings as soon as practicable and anticipates that its 2024 Form 10-K will include disclosures about substantial doubt regarding its ability to continue as a going concern.

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).
