Shuttle Pharmaceuticals Holdings, Inc. Announces Receipt of NASDAQ Noncompliance Letter
Rhea-AI Summary
Shuttle Pharmaceuticals (NASDAQ: SHPH) reported receiving a Nasdaq noncompliance notice after failing to file its Form 10-Q for the quarter ended June 30, 2026 by the required deadline, putting it in breach of Nasdaq Listing Rule 5250(c)(1) on periodic filings.
The company intends to file the Form 10-Q as soon as practicable and must submit a compliance plan to Nasdaq by October 27, 2026. If Nasdaq accepts the plan, Shuttle could receive up to 180 days from the original due date, or until February 22, 2027, to regain compliance.
The notice has no immediate impact on the listing or trading of SHPH shares, but the stock will be added to Nasdaq’s list of non-compliant companies around September 4, 2026, and flagged with a non-compliance indicator. Failure to regain compliance would subject the shares to potential delisting.

Gaithersburg, Maryland--(Newsfile Corp. - August 28, 2026) - Shuttle Pharmaceuticals Holdings, Inc. (NASDAQ: SHPH) (the "Company" or "Shuttle"), today announced that the Company is not in compliance with the periodic filing requirements for continued listing set forth in Nasdaq Listing Rule 5250(c)(1) as a result of its failure to file its Quarterly Report on Form 10-Q for the fiscal quarter ended June 30, 2026 with the Securities and Exchange Commission by the required due date.
The Company intends to file the Form 10-Q as soon as practicable.
The Company is required to submit a plan, by October 27, 2026, which outlines the steps the Company expects to take to regain compliance. If Nasdaq accepts the Company's plan, Nasdaq can grant an exception of up to 180 calendar days from the due date of the Form 10-Q, or until February 22, 2027, to regain compliance. However, there can be no assurance that Nasdaq will accept the Company's plan to regain compliance or that the Company will be able to regain compliance within any extension period granted by Nasdaq.
The Nasdaq Notice has no immediate effect on the listing or trading of the Company's common stock, though Nasdaq makes available to investors a list of non-compliant companies, which will include Shuttle beginning on approximately September 4, 2026. As part of this process, an indicator reflecting the Company's non-compliance will be broadcast over Nasdaq's market data dissemination network and will also be made available to third party market data providers. If the Company fails to timely regain compliance, the Company's common stock will be subject to delisting from Nasdaq.
