Resignation of Chief Financial Officer

On July 29, 2026, Shawna Bowin, the Chief Financial Officer of Expion360 Inc. (the "Company"), notified the board of directors of the Company that she is resigning from her role as Chief Financial Officer due to personal reasons. Ms. Bowin has agreed to continue serving in her current position to assist with the orderly transition of her roles and responsibilities through approximately October 31, 2026. The Company has commenced a search for a new Chief Financial Officer.

The Company confirms it has regained compliance with Nasdaq Listing Rule 5550(a)(2) and that its common stock, par value $0.001 per share (the "Common Stock"), continues to be listed and traded on The Nasdaq Capital Market.

As previously disclosed, on January 29, 2026, the Company received a staff determination from the Nasdaq Listing Qualifications department of The Nasdaq Stock Market ("Nasdaq") stating that the bid price of its Common Stock had closed below the $1.00 minimum required by Nasdaq Listing Rule 5550(a)(2) for the prior 30 consecutive trading days (the "Minimum Bid Price Requirement").

As of August 3, 2026, the Common Stock had closed above $1.00 per share for ten consecutive trading days. As a result, on August 4, 2026, the Company received a letter from the Nasdaq Office of General Counsel advising that the Company had regained compliance with the Minimum Bid Price Requirement, and that the Company was therefore in compliance with Nasdaq's listing requirements.
