Intrusion Inc Receives Nasdaq Delisting Notice

Intrusion Inc (INTZ) told the SEC on May 13 2026 that it had received a notice from Nasdaq stating the company is not in compliance with a listing rule.

The filing covers one public company with ticker INTZ and CIK 0000736012. Intrusion Inc is subject to the specific listing standard cited in the notice, though the exact rule violated is stated only as failure to satisfy a listing rule under Item 3.01.

Prior to the notice the company maintained Nasdaq listing and the associated reporting and governance obligations that come with it. The new state is that Nasdaq has formally notified Intrusion Inc of noncompliance. The notice triggers a cure period whose length is set by the exchange; the company must regain compliance within that window or submit a plan, or Nasdaq will move to delist the shares.

No specific cure deadline is disclosed in the 8-K beyond the standard timelines established by Nasdaq rules.

Downstream the company must now evaluate its options and communicate with Nasdaq within the exchange’s required response window. A successful cure would allow continued listing; failure to cure or to win an appeal would result in the stock moving to over-the-counter trading.

The company will be required to file any material update on the delisting process in a subsequent 8-K. Market participants who hold INTZ shares or trade its options face a change in liquidity venue and potential impact on margin or index eligibility if delisting proceeds.

Nasdaq’s decision also starts the clock on any separate SEC reporting obligations tied to exchange delisting.

This is the first such Item 3.01 disclosure by Intrusion Inc in the provided record. The 8-K itself constitutes the primary official notice to investors required under SEC rules when a company receives a delisting communication from its exchange.
