Key Terms

7 terms

listing rule 5250(c)(1) regulatory

"not in compliance with Nasdaq's continued listing standards as set forth in Listing Rule 5250(c)(1)"

A Nasdaq listing standard that requires companies traded on the exchange to file their regular financial reports with the U.S. Securities and Exchange Commission on time, such as annual and quarterly reports, and to notify Nasdaq if filings are late. It matters to investors because these filings provide the routine, reliable information needed to judge a company’s health; missing them can trigger warnings, trading suspension, or removal from the exchange, which can sharply affect liquidity and share value — like a business losing its operating license for failing inspections.

form 10-k regulatory

"file its Quarterly Report on Form 10-K for the period ended September 30, 2025"

A Form 10-K is a comprehensive report that publicly traded companies are required to file annually with regulators. It provides a detailed overview of a company's financial health, operations, and risks, similar to a detailed health report. Investors use this information to assess the company's performance and make informed decisions about buying or selling its stock.

form 10-q regulatory

"its Quarterly Reports on Forms 10-Q for the periods ended March 31, 2025, and June 30, 2025"

A Form 10-Q is a detailed report that publicly traded companies are required to file with regulators three times a year, providing an update on their financial health and business activities. It is important for investors because it offers timely insights into a company's performance, helping them make informed decisions about buying or selling stocks. Think of it as a regular check-up report that shows how well a company is doing.

u.s. securities and exchange commission regulatory

"with the U.S. Securities and Exchange Commission"

The U.S. Securities and Exchange Commission is a government agency responsible for overseeing the stock market and protecting investors. It sets rules to ensure that companies share truthful information and that trading is fair, helping to maintain trust in the financial system. This oversight is important because it helps prevent fraud and ensures that investors can make informed decisions.

nasdaq global market regulatory

"delisting the Company's Ordinary Shares from The Nasdaq Global Market"

The Nasdaq Global Market is a section of the stock exchange where larger, well-established companies are listed and publicly traded. It functions like a marketplace where investors can buy and sell shares of these companies, providing them with access to capital and opportunities for growth. Its role is important because it helps investors identify and invest in reputable companies with strong financial backgrounds.

nasdaq hearings panel regulatory

"the Company presented its plan of compliance before the Nasdaq Hearings Panel"

A Nasdaq hearings panel is a group of experts that reviews cases when a company's stock listing is at risk of being removed from the exchange. They evaluate whether the company has met certain standards and determine if it can keep trading on Nasdaq. This process matters to investors because it can affect a company's ability to raise money and maintain credibility in the market.

staff determination letter regulatory

"received an additional staff determination letter ("Staff Determination Letter") from the Listing Qualifications Department"

A staff determination letter is a written decision from the employees of a government or market regulator about a specific filing, application or compliance question; it tells a company whether the regulator accepts, rejects or needs more information. For investors, it matters because the letter can affect a company’s ability to sell securities, keep a stock listing, or move forward with a product or transaction—similar to a building inspector’s report that decides if construction can continue.

HOFFMAN ESTATES, Ill., Dec. 1, 2025 /PRNewswire/ -- Cambium Networks Corporation ("Cambium Networks" or the "Company") (NASDAQ: CMBM), a leading global provider of networking solutions, announced today that on November 25, 2025, the Company received an additional staff determination letter ("Staff Determination Letter") from the Listing Qualifications Department (the "Staff") of the Nasdaq Stock Market LLC ("Nasdaq") notifying the Company it was not in compliance with Nasdaq's continued listing standards as set forth in Listing Rule 5250(c)(1) (the "Filing Rule"), given the Company's inability to timely file its Quarterly Report on Form 10-K for the period ended September 30, 2025 ("Q3 2025 Delinquent Filing" and together with the prior delinquent filings referenced below, the "Delinquent Filings"), and that this matter serves as an additional basis for delisting the Company's Ordinary Shares from The Nasdaq Global Market.

As previously disclosed, the Company received deficiency letters from the Staff on April 16, 2025, May 22, 2025 and August 25, 2025 that the Company was not in compliance with the Filing Rule, since the Company had not yet filed its Annual Report on Form 10-K for the year ended December 31, 2024 and its Quarterly Reports on Forms 10-Q for the periods ended March 31, 2025, and June 30, 2025 with the U.S. Securities and Exchange Commission. The Staff had granted an extension of time until October 13, 2025 for the Company to regain compliance with the Filing Rule.

On November 11, 2025, the Company presented its plan of compliance before the Nasdaq Hearings Panel (the "Hearings Panel") and requested a continued stay of its delisting pending achieving full compliance by filing the Delinquent Filings within the time requested under the plan of compliance. There can be no assurance that the Hearings Panel will grant any of the Company's requests for additional time to gain compliance. As of the date of this press release, the Company's extended stay request remained under review by the Hearings Panel. Once the Hearings Panel makes a ruling on the extended stay, the Company intends to make a subsequent announcement. As the Company is already before the Hearings Panel, the Hearings Panel will consider the Q3 2025 Delinquent Filing in their decision regarding the Company's continued listing on The Nasdaq Global Market.
