Nasdaq Delisting Decision

As previously disclosed, Platinum Analytics Cayman Limited (the “Company”) received a Staff Delisting Determination (the “Staff Determination”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) notifying the Company that Nasdaq had determined to delist the Company’s securities pursuant to its discretionary authority under Nasdaq Listing Rule IM-5101-4. The Company appealed the Staff Determination by requesting a hearing before the Nasdaq Hearings Panel (the “Panel”) pursuant to Nasdaq Listing Rule 5815. The hearing was held on August 18, 2026.

On September 21, 2026, the Company received a notice from Nasdaq (the “Panel Decision”) notifying the Company that the Panel had determined to deny the Company’s request to reinstate trading on Nasdaq and to delist the Company’s securities. The Panel based its decision principally on trading activity indicative of potential manipulation and the Company’s failure to demonstrate sufficient liquidity to support a fair and orderly market. However, the Panel was unpersuaded by Staff’s arguments concerning the Company’s professional advisors, finding that their prior involvement with other companies that had experienced trading halts, anomalous trading or FINRA enforcement matters did not, standing alone, constitute valid grounds for delisting. The Panel also found that the residence of the Company’s chief executive officer in Singapore did not support delisting. Trading in the Company’s securities was suspended at the opening of trading on September 23, 2026.

The Company intends to request that the Nasdaq Listing and Hearing Review Council review the Panel Decision pursuant to Nasdaq Listing Rule 5820. A request for review by the Listing and Hearing Review Council will not stay the suspension of trading in, or the delisting of, the Company’s securities.

The Company issued a press release on September 26, 2026, announcing the receipt of the Panel Decision. A copy of this press release is attached hereto as Exhibit 99.1 and is incorporated by reference herein.
