Cambium Networks faces Nasdaq delisting after appeal fails

What happened

Cambium Networks Corporation, a Cayman Islands company that designs and sells wireless broadband equipment through its U.S. unit, said on August 31, 2026, that it received a decision from the Nasdaq Listing and Hearing Review Council affirming an earlier ruling to delist its ordinary shares from Nasdaq.

The delisting is based on the company's prior failure to comply with Nasdaq Listing Rule 5250(c)(1), which requires companies to timely file required reports with the SEC. Trading in Cambium's shares on Nasdaq has been suspended since March 27, 2026. The Nasdaq board may, at its discretion, review the Listing Council's decision, but the company said it expects its shares to continue trading on the OTC Markets Group's Expert Market.

On the day of the filing, the stock closed at $0.0901, down 9.9% from the previous close of $0.10.

The filing

The disclosure was made in a Form 8-K filed with the SEC on August 31, 2026, under Item 3.01, which requires companies to report any notice of delisting or failure to satisfy a continued listing rule.

The company received the Listing Council's decision on August 25, 2026. The decision affirms the March 25, 2026 determination of a Nasdaq Hearings Panel to delist the shares.

Cambium says its ordinary shares are expected to continue to be available for quotation on the OTC Markets Group's Expert Market, though the company notes that Nasdaq may still call the decision for review.

What this means

A Form 8-K is a current report that companies must file to announce major events. Item 3.01 specifically requires disclosure when a company receives a delisting notice or fails to meet a listing standard, and this filing is how Cambium is telling investors about the final appeal outcome.

Nasdaq Listing Rule 5250(c)(1) requires listed companies to file quarterly and annual reports with the SEC on a timely basis. The rule is designed to keep investors informed by ensuring financial data is current. The company's failure to meet that obligation triggered the delisting process, which began with a hearing panel and is now at the Listing Council level.

The company did not explain in this filing why it failed to file on time, and the filing does not state whether the Nasdaq board will review the decision.

Because the shares were already suspended in March, the practical effect for investors is that they now move to the OTC Markets Expert Market. OTC Expert Market is a trading platform for securities that are not listed on a national exchange, often with less public information and lower liquidity. The company's ability to remain listed depends on Nasdaq's final decision, which the filing says is at the Nasdaq board's discretion.
