Cambium Networks (CMBM) to move from Nasdaq to OTC markets after delisting

Rhea-AI Filing Summary

Cambium Networks Corporation reported that the Nasdaq Hearings Panel has decided to delist its ordinary shares from The Nasdaq Stock Market after the company failed to comply with milestones in a prior panel decision. Trading on Nasdaq will be suspended at the open on March 27, 2026. Cambium expects its shares to be quoted on OTC Markets, initially on the OTC Pink Limited tier and then the Expert Market, which the company warns may materially reduce trading price, liquidity, transparency, and increase volatility. The company is considering whether to appeal the delisting decision to the Nasdaq Listing and Hearing Review Council, but any appeal would not prevent the Nasdaq trading suspension.

Equity market structure analyst

Nasdaq delisting pushes CMBM to OTC venues with likely lower liquidity.

Cambium Networks is being delisted from Nasdaq after not meeting conditions tied to filing required periodic SEC reports. Its ordinary shares will stop trading on Nasdaq on March 27, 2026, ending access to a major national exchange.

The company expects trading to move first to the OTC Pink Limited tier and then the Expert Market. These venues typically have less stringent reporting visibility, which the company notes can mean reduced liquidity, less transparency and greater price volatility for its ordinary shares.

Cambium is weighing an appeal to the Nasdaq Listing and Hearing Review Council, but any review would not halt the Nasdaq suspension. Future disclosures in company filings may clarify whether an appeal is pursued and whether the company seeks a path back to an exchange listing.

Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On March 25, 2026, Cambium Networks Corporation (“Cambium” or the “Company”) received a written notice (the “Delist Determination”) that the Nasdaq Hearings Panel (the “Hearings Panel”) has determined to delist the Ordinary Shares of the Company from The Nasdaq Stock Market (“Nasdaq”) due to the Company's failure to comply with the terms of the Hearings Panel's Decision.

Trading in the Company's Ordinary Shares will be suspended at the open of trading on March 27, 2026.

The Company is considering whether to request an appeal of the Delist Determination to the Nasdaq Listing and Hearing Review Council (the “Council”) in accordance with Nasdaq Listing Rule 5820(a). Such request would not stay the suspension of trading the Ordinary Shares on Nasdaq. The Company expects the Ordinary Shares will be immediately eligible for quotation on the OTCID market operated by OTC Markets under its trading symbol: CMBM, which may have a material adverse effect on the trading price and volume for the Ordinary Shares. There can be no assurance that a market for the Ordinary Shares will develop or be maintained on the OTCID market, and the Company's shareholders may find it more difficult to buy or sell their shares.

On March 26, 2026, the Company issued a press release announcing its receipt of the Delist Determination. A copy of the press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.

FAQ

Why is Cambium Networks (CMBM) being delisted from Nasdaq?

Cambium Networks is being delisted because a Nasdaq Hearings Panel determined the company failed to comply with the terms of a prior decision that granted it an extension, including milestones for filing certain periodic reports with the SEC. This noncompliance led directly to the delisting determination.

When will Cambium Networks shares stop trading on the Nasdaq Global Market?

Trading in Cambium Networks’ ordinary shares on Nasdaq will be suspended at the open of trading on March 27, 2026. After that, the shares will no longer trade on the Nasdaq Global Market, and investors must use alternative markets once quotation transitions occur.

Where will Cambium Networks (CMBM) shares trade after the Nasdaq delisting?

Cambium Networks expects its ordinary shares to be quoted on the OTC Markets system, initially on the OTC Pink Limited tier, then moving to the Expert Market. The company cautions that these venues may bring reduced liquidity, less transparency, and greater price volatility for investors.

Is Cambium Networks appealing the Nasdaq delisting decision?

Cambium Networks is considering whether to request that the Nasdaq Listing and Hearing Review Council review the delisting decision under Nasdaq Listing Rule 5820(a). Any such request would not stay the suspension of trading of its ordinary shares on Nasdaq during the review process.

How might the Nasdaq delisting affect Cambium Networks shareholders?

The company states the shift from Nasdaq to OTC markets may have a material adverse effect on trading price and volume. Shareholders may face reduced liquidity, less transparency into trading, greater price volatility, and potentially more difficulty buying or selling Cambium Networks shares.

What did Cambium Networks disclose about its prior Nasdaq compliance extension?

Cambium Networks disclosed it previously received an extension for continued Nasdaq listing, subject to meeting milestones set in a December 3, 2025 decision. Those milestones required filing certain periodic SEC reports, and failure to meet them led to the Nasdaq Hearings Panel’s delisting determination.
