Form 20-F ☒ Form 40-F ☐

OnEXHIBIT October 15, 2025, STAK Inc., a Cayman Islands exempted company (the “Company”), received a notice (the “Notice”) from the Nasdaq Listing Qualifications Department of the Nasdaq Stock Market LLC (“Nasdaq”), stating that the Company’s Class A ordinary shares, par value $0.001 per share (the “Class A Ordinary Shares”), fail to comply with the $1.00 minimum bid price requirement for continued listing on Nasdaq in accordance with Nasdaq Listing Rule 5550(a)(2) based upon the closing bid price of the Class A Ordinary Shares for the 30 consecutive business days prior to the date of the Notice.INDEX

Pursuant to Nasdaq Listing Rule 5810(c)(3)(A), the Company has been provided an initial compliance period of 180 calendar days, or until April 13, 2026, to regain compliance with the minimum bid price requirement. To regain compliance, the closing bid price of the Class A Ordinary Shares must be at least $1.00 for at least 10 consecutive business days (with such compliance period extendable at the discretion of Nasdaq) prior to April 13, 2026. Nasdaq would then provide a written confirmation of compliance and the matter will be closed.

Exhibit No.		Description
99.1		STAK Inc. Announces Closing of US$2.3 Million Registered Direct Offering

If the Company is unable to regain compliance by April 13, 2026, the Company may be eligible for an additional 180 calendar day compliance period to demonstrate compliance with the minimum bid price requirement. To qualify, the Company will be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, with the exception of the minimum bid price requirement, and will need to provide written notice to Nasdaq of its intention to cure the deficiency during the second compliance period, by effecting a reverse stock split, if necessary, and it must otherwise appear to Nasdaq that the Company is capable of curing the deficiency. If the Company does not qualify for the second compliance period or fails to regain compliance during the second 180 calendar day period, then Nasdaq will notify the Company of its determination to delist the Class A Ordinary Shares, at which point the Company would have an opportunity to appeal the delisting determination to a Hearings Panel.SIGNATURES

The Company will monitor the closing bid price of its Class A Ordinary Shares. Receipt of the Notice has no effect on the Company’s business operations.
