(NASDAQ:GURE) ("Gulf Resources," "we," or the "Company"), a leading manufacturer of bromine and crude salt in China, today announced that it received a delinquency notification letter (the "Notice") from the Listing Qualification Staff (the "Staff") of the Nasdaq Stock Market LLC ("Nasdaq") on May 26, 2026 due to the Company's non-compliance with Nasdaq Listing Rule 5250(c)(1) (the "Listing Rule") as a result of the Company's failure to timely file its quarterly report on Form 10-Q for the period ended March 31, 2026 (the "Form 10-Q"). The Listing Rule requires listed companies to timely file all required periodic financial reports with the Securities and Exchange Commission.

This Notice has no immediate effect on the listing of the Company's securities on Nasdaq.

As previously disclosed in the press release distributed by the Company on April 27, 2026, the Company received a delinquency notification letter on April 23, 2026 due to the Company's non-compliance with Listing Rule as a result of the Company's failure to timely file its Annual Report on Form 10-K (the "Form 10-K") for the period ended December 31, 2025 (the "Initial Delinquent Filing"). As of the date of this press release, the Company remains delinquent in filing its Annual Report on Form 10-K. The Company must submit a plan to regain compliance with respect to these delinquent reports no later than June 22, 2026. If Nasdaq accepts the Company's plan, then Nasdaq may grant the Company up to 180 calendar days from the due date of the Initial Delinquent Filing, or until October 12, 2026 to regain compliance. If Nasdaq does not accept the Company's plan, then the Company will have the opportunity to appeal that decision to a Nasdaq Hearings Panel.

The Company is working diligently to complete its Form 10-K and Form 10-Q.

This announcement is made in compliance with the Nasdaq Listing Rule 5810(b), which requires prompt disclosure of receipt of a notification of deficiency.
