Item 3.03 Material Modification to Rights of Security Holders.

On August 22, 2025, Yunhong Green CTI, Ltd. (the “Company”) received approval from its stockholders to effect a reverse stock split (the “Reverse Stock Split”) at a ratio of one-for-ten (1:10) (the “Exchange Ratio”) of the Company’s common stock, no par value (the “Common Stock”), and a corresponding reduction of the Company’s authorized shares of Common Stock (the “Authorized Share Reduction”). The Reverse Stock Split is expected to become effective by 9:00 a.m. Eastern Time on October 1, 2025 (the “Effective Time”).

The Common Stock is expected to commence trading on a reverse split-adjusted basis at around 9 a.m. Eastern Time on October 1, 2025 under the existing trading symbol “YHGJ.” The new CUSIP number for the Common Stock following the Reverse Stock Split is 98873Q 209.

The Reverse Stock Split will affect all stockholders uniformly and will not alter any stockholder’s percentage ownership interest or proportionate voting power in the Company’s equity, except for de minimis changes as a result of the elimination of fractional shares. No fractional shares will be issued in connection with the Reverse Stock Split. Stockholders who would otherwise be entitled to a fractional share of Common Stock are instead entitled to a cash payment equal to their respective pro rata portion of the total net proceeds from the sale of all aggregated fractional shares promptly after the Effective Time at the then-prevailing prices on the open market. The Reverse Stock Split will reduce the number of shares outstanding from 27,738,626 to 2,773,862, subject to adjustment for fractional shares.
