Protagenic Therapeutics got a Nasdaq warning for falling below equity and filing rules, risking delisting.
Protagenic Therapeutics (PTIX) received a Nasdaq notice on November 27, 2025, stating it no longer complies with two listing rules: minimum stockholders’ equity of $2.5 million and timely filing of periodic reports.
The issues stem from a June 30, 2025, report showing insufficient equity and a delay in filing its third-quarter 2025 Form 10-Q.
The company is finalizing the overdue report and plans to request a hearing before a Nasdaq panel to seek a stay and additional time to regain compliance.

The stock will continue trading during the process.
