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

On October 15, 2025, Yunhong Green CTI Ltd. (“CTI” or the “Company”), received written notice from the Nasdaq Capital Market (“Nasdaq”) that the Company had regained compliance with Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Rule”).

On October 21, 2024, the Company received written notice from The Nasdaq Capital Market (“Nasdaq”) stating that the Company was not in compliance with Nasdaq Listing Rule 5550(a)(2) (the “Minimum Bid Price Rule”) because the Company’s common stock failed to maintain a minimum closing bid price of $1.00 for 30 consecutive business days. The Notice has no immediate effect on the Nasdaq listing or trading of the Company’s common stock. This Notice provided an initial 180 calendar day period, or until April 21, 2025, in which to regain compliance, pursuant to Listing Rule 5810(c)(3)(A).

The Company was unable to gain compliance within the initial 180-day grace period, therefore on April 24, 2025, a second grace period was granted by Nasdaq which allowed the Company an additional 180-day period or until October 19, 2025 to regain compliance. The Company committed to effect a reverse stock split, if necessary, in order to regain compliance. On August 22, 2025, the Company received approval from its stockholders to effect a reverse stock split at a ratio of one-for-ten (1:10) of the Company’s common stock, no par value. The reverse stock split became effective on October 1, 2025.

This summary is not intended to include all terms of the Notice, which is filed as Exhibit 99.1 to this Current Report on Form 8-K and are incorporated by reference into this Item 3.01.
