Intrusion stock holds at USD 2.16 after a 380 percent move

Intrusion Inc. (ISIN US46121H1095) stock closed at USD 2.16 on Nasdaq on September 22, 2026, after gaining USD 1.71, or 380 percent, from the prior close. The move is the clearest dated market signal available for the cybersecurity company.

Price move sets the key signal

Data published by Zacks show a last price of USD 2.16 and a daily change of USD 1.71, equivalent to 380 percent, for September 22, 2026. The same page lists an after-hours price of USD 2.00, down USD 0.16, or 7.41 percent, at 7:58 p.m. ET on that date.

That comparison matters because the regular-session gain and the after-hours pullback point to a sharp change in trading conditions rather than a small incremental repricing. The two quoted levels differ by USD 0.16, giving investors a concrete measure of the post-close reversal.

Latest operating figures need period context

Intrusion's latest operating figures should be read together with their explicitly reported period and the company's own filing calendar. The investor-relations start page is available at Intrusion, while the dated market record supplies the measurable September 2026 trading context.

For the stock, the immediate analytical issue is therefore the durability of the USD 2.16 regular-session close versus the USD 2.00 after-hours indication, not an undated earnings headline. A 380 percent session gain creates a comparison base that can make subsequent percentage changes look large even when the absolute price difference is measured in cents.
