Reverse Stock-Split to be effective on October 7, 2026

HONG KONG, Oct. 2, 2026 /PRNewswire/ -- SU Group Holdings Limited (NASDAQ:SUGP) ("SU Group" or the "Company"), an integrated security-related engineering services company in Hong Kong, today announced that it will effect a 1-for-6 reverse stock split ("Share Consolidation") of its class A ordinary shares, par value HK$0.000005 per share ("Ordinary Shares"). This action was approved by the board of directors of the Company on September 18, 2026 and by written resolution of the Company's majority shareholders on September 18, 2026.

Share Consolidation

The Share Consolidation, approved as an ordinary resolution, will combine every six Class A Ordinary Shares into one Ordinary Share with a par value of HK$0.00003. The Share Consolidation will become effective at 12:01 a.m. Eastern Time on Wednesday October 7, 2026, and the Company's Class A Ordinary Shares will commence trading on the Nasdaq Capital Market on a post-split basis at the opening of the market on Wednesday October 7, 2026. The Company's Class A Ordinary Shares will continue to trade on the Nasdaq Capital Market under the Company's existing trading symbol, "SUGP," and a new CUSIP number G8552M158 has been assigned as a result of the Share Consolidation.

The Share Consolidation will reduce the number of issued and outstanding Ordinary Shares of the Company from approximately 9,010,733 to approximately 1,501,789. No fractional shares will be issued. Each shareholder will be entitled to receive one consolidated share in lieu of any fractional share, resulting in all fractional shares being rounded up to the nearest whole number.

The 1-for-6 Share Consolidation (the "Ratio") will automatically combine and convert 6 current Ordinary Shares into 1 issued and outstanding new Ordinary Share. The Company's transfer agent, Transhare Corporation, will serve as exchange agent for the Share Consolidation. Registered shareholders holding pre-split Ordinary Shares electronically in book-entry form are not required to take any action to receive post-split shares. Shareholders owning shares via a broker, bank, trust or other nominee will have their positions automatically adjusted to reflect the Share Consolidation, subject to such broker's particular processes, and will not be required to take any action in connection with the Share Consolidation. Holders of stock certificates will need to send their old physical certificates with a letter of transmittal to receive their new post-Share Consolidation certificate.

Additional Information

Each outstanding stock option, warrant, restricted share unit, or other security convertible into pre-Share Consolidation Ordinary Shares that has not been exercised or cancelled prior to the effective date will be adjusted pursuant to the terms of the instrument or plan governing such security based on the 1-for-6 ratio. The Share Consolidation will change the par value of the Ordinary Shares from HK$0.000005 to HK$0.00003 and the authorized number of shares will be correspondingly reduced as described. The trading of the Company's Class A Ordinary Shares on Nasdaq is expected to continue without disruption, subject to compliance with Nasdaq listing requirements.
