On April 13, 2026, Golden Sun Technology Group Limited (the “Company”) received a deficiency notice (the “Notification Letter”) from the Listing Qualifications Department (the “Staff”) of the Nasdaq Stock Market (“NASDAQ”) informing the Company that its Class A ordinary shares failed to maintain a minimum bid price of $1.00 per share over the last 30 consecutive business days as required by the Listing Rules 5550(a)(2) of the NASDAQ. The Notification Letter does not impact the Company’s listing on the Nasdaq Capital Market at this time.

In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided 180 calendar days, or until October 12, 2026 (the “Compliance Date”), to regain compliance with Nasdaq Listing Rule 5550(a)(2). To regain compliance, the Company’s Class A ordinary shares must have a closing bid price of at least US$1.00 for a minimum of 10 consecutive business days, and must not have a closing bid price of $0.10 or less for over 10 consecutive trading days by the Compliance Date. In the event the Company does not regain compliance by the Compliance Date, the Company may be eligible for additional time to regain compliance or may face delisting.

If the Company does not regain compliance with the minimum bid price requirement as set forth in Nasdaq Listing Rule 5550(a)(2) by the Compliance Date and is not eligible for an additional compliance period at that time, the Staff will provide written notification to the Company that its Class A ordinary shares may be delisted. The Company would then be entitled to appeal the Staff’s determination to a NASDAQ Listing Qualifications Panel and request a hearing. There can be no assurance that, if the Company does appeal the delisting determination by the Staff to the NASDAQ Listing Qualifications Panel, that such appeal would be successful.

The Company intends to monitor the closing bid price of its Class A ordinary shares and may, if appropriate, consider available options to regain compliance with the minimum bid price requirement, which could include effecting a reverse stock split. However, there can be no assurance that the Company will be able to regain compliance with the minimum bid price requirement.
