Rhea-AI Filing Summary

CERO Therapeutics Holdings reported that a Nasdaq Hearings Panel denied its request for continued listing, citing noncompliance with the Nasdaq Capital Market’s minimum stockholders’ equity requirement of $2,500,000 under Rule 5550(b). As a result, CERO’s common stock will be suspended from trading on October 31, 2025.

The company has requested review by the Nasdaq Listing and Hearing Review Council and has begun the process to trade on the OTC Markets, while also considering other exchange options. CERO plans to continue its clinical trials, noting early observations for CER-1236 in initial AML patients at low dose with rapid cell expansion and no observed toxicity, and intends to proceed to higher dosing. The company is reviewing cash resources and potential financing alternatives and states there is no assurance of obtaining financing on acceptable terms, or at all.

Positive

  • None.

Negative

  • Nasdaq trading suspension effective October 31, 2025, following noncompliance with the $2,500,000 stockholders’ equity requirement, increasing liquidity and pricing risk.
  • Company discloses review of cash resources and financing alternatives with no assurance of obtaining financing, signaling funding uncertainty.

Insights

Nasdaq suspension is a material trading and liquidity setback.

The panel’s denial and suspension on October 31, 2025 move CERO off Nasdaq after failing the $2,500,000 stockholders’ equity requirement under Rule 5550(b). Delisting typically reduces visibility and may widen bid-ask spreads versus a national exchange listing.

The company will seek review by the Council and is pursuing OTC Markets while evaluating other exchanges. Actual trading venue and liquidity will depend on acceptance outcomes; the filing notes the OTC Markets are less liquid, which can affect trading price and volume.

CERO highlights ongoing clinical trials and early observations for CER-1236 at low dose. However, the company is assessing cash resources and financing alternatives with no assurance of success, so capital availability remains a key dependency for trial progression.

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

 

As previously disclosed, on August 28, 2025, CERo Therapeutics Holdings, Inc., a Delaware corporation (the “Company”), received a letter from the staff at the Nasdaq Listing Qualifications department notifying the Company that such staff had determined that the Company does not comply with the minimum stockholders’ equity requirement of $2,500,000 (the “Stockholders’ Equity Requirement”) for continued listing on the Nasdaq Capital Market (“Nasdaq”) set forth in Nasdaq Rule 5550(b).

 

As also previously disclosed, on September 3, 2025, the Company requested a hearing to appeal such determination before a panel (the “Hearings Panel”). On October 29, 2025, the Company received the determination of the Hearings Panel to deny the Company’s request for the continued listing of its common stock. As a result, the common stock will be suspended from trading on Nasdaq at open of trading on October 31, 2025.

 

The Company has submitted a request for review of the Hearings Panel’s decision by the Nasdaq Listing and Hearing Review Council (the “Council”). The Company has also commenced the process of seeking to trade its shares of common stock on the OTC Markets. However, the Company can provide no assurance that the review by the Council will result in the continued listing of its shares of common stock or that the shares of common stock will be admitted for trading on the OTC Markets. The OTC Markets also are a less liquid market than Nasdaq, which may have a material adverse effect on the trading price and volume for the common stock. The Company is also considering listing alternatives, including applying to list its shares of common stock on another securities exchange.

 

The Company currently plans to continue its clinical trials, including the dosing of patients in such trials. As described previously by CERO, evidence gathered for CER-1236 in the first three AML cancer patients dosed at the initial low dose showed rapid cell expansion of CER-1236 in these patients, along with observation of no toxicity.  Moreover the second patient, infused with three of the low doses in succession, continues on trial.  The company believes these early stage observations support continued clinical development of CER-1236 at the planned higher dose, and is progressing on this plan. The Company is currently reviewing its cash resources and potential financing alternatives to fund its continued operations. The Company can provide no assurance that it will be able to obtain such financing on acceptable terms, or at all.

 

Item 8.01. Other Events. 

 

On October 29, 2025, the Company issued a press release announcing the Hearings Panel’s determination. Such press release is filed as Exhibit 99.1 hereto and is hereby incorporated by reference herein.
