Protagenic Therapeutics, Inc. (the “Company”) will not be able to file its Quarterly Report on Form 10-Q for the period ended June 30, 2025 by the prescribed due date without unreasonable effort or expense.

On August 8, 2025, the Board of Directors approved a restructuring plan to transition to a virtual operating model and exit or modify certain obligations. To ensure complete and accurate reporting, management is finalizing the related accounting and disclosures, including:

1. Measuring and recording exit and disposal costs (e.g., severance and contract terminations) and determining the appropriate timing of recognition under applicable U.S. GAAP;

2. Classifying and presenting restructuring charges and related operating expenses; and

3. Updating “Subsequent Events,” “Liquidity and Capital Resources,” and related risk disclosures to reflect the plan and its expected cash flow impacts.

These procedures are being completed with Audit Committee oversight and consultation with the Company’s external advisors.

The Company expects to file the Form 10-Q on or before August 19, 2025, within the five-day extension permitted by Rule 12b-25. The Company does not anticipate reporting a significant change in results of operations for the quarter ended June 30, 2025 as compared to the corresponding period in the prior year.
