Failure to Satisfy Listing Rule (Form 8-K)

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

On August 19, 2026, K&F Growth Acquisition Corp. II (the "Company") received a written notice (the "Notice") from the Nasdaq Listing Qualifications Department of The Nasdaq Stock Market ("Nasdaq") indicating that the Company was not in compliance with Listing Rule 5450(a)(2), which requires the Company to have at least 400 Total Holders for continued listing on the Nasdaq Global Market (the "Minimum Total Holders Requirement"). The Notice is only a notification of deficiency, not of imminent delisting, and has no current effect on the listing or trading of the Company's securities on Nasdaq Global Market and, as of August 21, 2026, the Class A ordinary shares of the Company will continue to trade on Nasdaq Global Market under the symbol "KFII".

The Notice states that the Company has 45 calendar days to submit a plan to regain compliance with the Minimum Total Holders Requirement. If Nasdaq accepts the Company's plan, Nasdaq may grant the Company an extension of up to 180 calendar days from the date of the Notice to evidence compliance with the Minimum Total Holders Requirement. If Nasdaq does not accept the Company's plan, the Company will have the opportunity to appeal the decision in front of a Nasdaq Hearings Panel.

The Company will consider implementing available options to regain compliance with the Minimum Total Holders Requirement. Alternatively, the Company may consider applying to transfer its securities to The Nasdaq Capital Market.

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