INFORMATION CONTAINED IN THIS FORM 6-K REPORT

On December 29, 2025 and December 31, 2025, Big Tree Cloud Holdings Limited (the “Company”) received two written notifications (the “Notification Letters”) from The Nasdaq Stock Market LLC (“Nasdaq”), notifying the Company that it is not in compliance with the minimum Market Value of Listed Securities (“MVLS”) of US$50,000,000 and the minimum Market Value of Publicly Held Shares (“MVPHS”) of US$15,000,000 set forth in Nasdaq Listing Rules for continued listing on the Nasdaq Global Market.

On December 29, 2025, the Company received a notification letter from Nasdaq, based on Nasdaq’s review of the Company’s MVLS for at least 30 consecutive business days from November 13, 2025 to December 26, 2025, the Company’s MVLS was below the required minimum of US$50,000,000. Pursuant to Nasdaq Listing Rule 5810(c)(3)(C), the Company has been granted a 180-calendar-day compliance period, or until June 29, 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 ten consecutive business days during the compliance period. The letter notifies the Company of a deficiency but does not immediately affect its Nasdaq listing status.

On December 31, 2025, the Company received an additional notification letter from Nasdaq, based on Nasdaq’s review of the Company’s MVPHS for at least 30 consecutive business days from November 6, 2025 to December 30, 2025, the Company’s MVPHS was below the required minimum of US$15,000,000. Pursuant to Nasdaq Listing Rule 5810(c)(3)(D), the Company has been granted a 180-calendar-day compliance period, or until June 29, 2026, 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. The letter notifies the Company of a deficiency but does not immediately affect its Nasdaq listing status.

Both notification letters have no immediate effect on the listing or trading of the Company’s ordinary shares. The Company will consider available options during this period to restore compliance with Nasdaq listing requirements. The Company remains committed to executing its long-term business strategy and enhancing shareholder value.
