10. Yunhong Green CTI Ltd. (NASDAQ:YHGJ)

Yunhong Green, formerly CTI Industries, rallied by 64 percent last week to close at $1 apiece as investors gobbled up shares in the company to boost its price above the $1 minimum requirement of the Nasdaq exchange to remain as a listed firm.

On October 21, YHGJ received a letter from Nasdaq notifying the company of its noncompliance with the minimum threshold. The letter was based on its share price, which fell below the $1 level for 30 consecutive days since September 10, 2024.

YHGJ said it was given 180 days upon receipt of the letter, or until April 21, 2025, to comply with the threshold; otherwise, it could face a potential delisting.

To meet the requirements, the closing bid price of Yunhong Green CTI’s common stock must reach $1.00 or more per share for at least 10 consecutive business days within this period.
