INFORMATION CONTAINED IN THIS FORM 6-K REPORT

Receipt of Nasdaq Notification Regarding Minimum Market Value of Publicly Held Shares

On August 6, 2026, Xiao-I Corporation (the “Company”) received a written notification (the “Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Company is not in compliance with the minimum market value of publicly held shares (“MVPHS”) requirement set forth in Nasdaq Listing Rule 5450(b)(3)(C).

Nasdaq Listing Rule 5450(b)(3)(C) requires a company listed on The Nasdaq Global Market under the applicable continued listing standard to maintain an MVPHS of at least US$15,000,000. The Notice stated that, based on the closing bid price of the Company’s American Depositary Shares (“ADSs”) for the 30 consecutive business days from June 23, 2026 through August 4, 2026, the Company’s MVPHS was below US$15,000,000.

The Notice has no immediate effect on the listing or trading of the Company’s ADSs, which will continue to be listed and traded on The Nasdaq Global Market under the symbol “AIXI,” subject to the Company’s compliance with Nasdaq’s other continued listing requirements.

In accordance with Nasdaq Listing Rule 5810(c)(3)(D), the Company has been provided a compliance period of 180 calendar days, or until February 1, 2027, to regain compliance with the MVPHS requirement. To regain compliance, the Company’s MVPHS must close at US$15,000,000 or more for a minimum of ten consecutive business days during the compliance period, unless Nasdaq exercises its discretion to require a longer compliance period.

If the Company does not regain compliance by the expiration of the compliance period, Nasdaq will provide written notification that the Company’s securities are subject to delisting. At that time, the Company may appeal Nasdaq’s determination to a hearings panel in accordance with the applicable Nasdaq Listing Rules.

The Company intends to actively monitor its MVPHS and evaluate available options to regain compliance within the prescribed compliance period. There can be no assurance, however, that the Company will be able to regain compliance with the MVPHS requirement within the applicable compliance period or maintain compliance with Nasdaq’s other continued listing requirements.

This report may contain forward-looking statements. These statements involve risks and uncertainties, and actual results may differ materially from those expressed or implied by such statements. The Company undertakes no obligation to update any forward-looking statement except as required by applicable law.
