SU
Group Holdings Limited Announces Reverse Stock Split
Reverse
Stock-Split to be effective on August 6, 2026
HONG
KONG, August 4, 2026 -- 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-5 reverse
stock split (“Share Consolidation”) of its class A ordinary shares, par value HK$0.000001 per share (“Ordinary
Shares”). This action was approved by the board of directors of the Company on July 23, 2026 and by written resolution of
the Company’s majority shareholders on July 23, 2026.
Share
Consolidation
The
Share Consolidation, approved as an ordinary resolution, will combine every five Class A Ordinary Shares into one Ordinary Share
with a par value of HK$0.000005. The Share Consolidation will become effective at 12:01 a.m. Eastern Time on Thursday, August
6, 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 Thursday, August 6, 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 G8552M141
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 7,124,092
to approximately 1,424,819. 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-5 Share Consolidation (the “Ratio”) will automatically combine and convert 5 current Ordinary Shares into 1
issued and outstanding new Ordinary Share. The Company’s transfer agent, Transhare Corporation, will serve as exchange 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-5 ratio. The Share Consolidation will change the par value of the Ordinary
Shares from HK$0.000001 to HK$0.000005 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.
