Item 3.01 Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On April 17, 2026, YHN Acquisition I Limited (the “Company”) received a notification letter (the “Notification Letter on MVPHS”) from The Nasdaq Stock Market LLC (“Nasdaq”) that the Company is not in compliance with the minimum Market Value of Publicly Held Shares (the “MVPHS”) set forth in Nasdaq Listing Rule 5450(b)(2)(C) for continued listing on Nasdaq, which requires a minimum MVPHS of $15,000,000 (the “MVPHS Requirement”), since the Company failed to meet the MVPHS Requirement for a period of 30 consecutive business days from March 5, 2026 to April 16, 2026. The Notification Letter on MVPHS has no immediate effect on the listing or trading of the Company’s Ordinary Shares on Nasdaq and, as of April 20, 2026, the Ordinary Shares will continue to trade on Nasdaq under the symbol “YHNA.”

The Notification Letter on MVPHS provides that pursuant to Nasdaq Listing Rule 5810(c)(3)(D), the Company has 180 calendar days, or until October 14, 2026, to regain compliance with Nasdaq Listing Rule 5450(b)(2)(C). To regain compliance, the minimum MVPHS must be at least $15,000,000 or more for a minimum of 10 consecutive business days prior to October 14, 2026. If the Company does not regain compliance by October 14, 2026, the Company will receive written notification from Nasdaq that its securities are subject to delisting. Alternatively, the Company may consider applying for a transfer to The Nasdaq Capital Market (the “Capital Market”). In order to transfer, the Company must submit an on-line transfer application, and meet the Capital Market’s continued listing requirements.

Additionally, on April 17, 2026, the Company received a separate notification letter (the “Notification Letter on MVLS”) from Nasdaq, indicating that the Company was no longer in compliance with the minimum Market Value of Listed Securities (“MVLS”) of $50,000,000 required for continued listing on The Nasdaq Global Market, as set forth in Nasdaq Listing Rule 5450(b)(2)(A) (the “MVLS Requirement”) since the Company failed to meet the MVLS Requirement for a period of 30 consecutive business days from March 5, 2026 to April 16, 2026. The Notification Letter on MVLS has no immediate effect on the listing or trading of the Company’s Ordinary Shares on Nasdaq and, as of April 20, 2026, the Ordinary Shares will continue to trade on Nasdaq under the symbol “YHNA.”

In accordance with Nasdaq Listing Rule 5810(c)(3)(C), the Company has a period of 180 calendar days, or until October 14, 2026, to regain compliance with the MVLS Requirement. To regain compliance, the Company’s MVLS must close at $50,000,000 or more for a minimum of 10 consecutive business days prior to October 14, 2026. If the Company does not regain compliance by October 14, 2026, the Company will receive written notification from Nasdaq that its securities are subject to delisting. Alternatively, the Company may consider applying for a transfer to the Capital Market. In order to transfer, the Company must submit an on-line transfer application, and meet the Capital Market’s continued listing requirements.

The Company intends to monitor the MVPHS Requirement and MVLS Requirement of its Ordinary Shares and will consider implementing available options to regain compliance with the MVPHS Requirement and MVLS Requirement under the Nasdaq Listing Rules.

This announcement is made in compliance with Nasdaq Listing Rule 5810(b), which requires prompt disclosure of receipt of a deficiency notification.

For example, there can be no assurance that Nasdaq will accept the Company’s plan to regain compliance or that the Company will regain compliance with the Nasdaq listing rules during any compliance period or in the future, or otherwise meet Nasdaq continued listing standards. For additional information about factors that could cause actual results to differ materially from those described in the forward-looking statements, please refer to the Company’s filings with the SEC.
