Item 8.01. Other Events.

As previously reported on K&F Growth Acquisition Corp. II’s (the “Company”) Current Report on Form 8-K filed with the Securities and Exchange Commission on August 21, 2026, the Company previously received a letter (the “Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market (“Nasdaq”) notifying the Company that it was not in compliance with Nasdaq Listing Rule 5450(a)(2), which requires the Company to maintain at least 400 total holders for continued listing on the Nasdaq Global Market.

In connection with the foregoing, the Company submitted an application for a transfer of its listed securities from the Nasdaq Global Market to the Nasdaq Capital Market on August 26, 2026 (the “Application”). The Application to transfer the listing of its securities was granted on September 14, 2026, and the transfer became effective on September 16, 2026 (“Transfer”). As a result of the Transfer, the deficiency cited in the Total Shareholder Notice has been rendered moot.
