Expert Systems Holdings Limited

Shareholders of Expert Systems Holdings Limited

As a company listed on the GEM board of The Stock Exchange of Hong Kong Limited (stock code 8319), Expert Systems Holdings Limited’s shareholder disclosure follows Part XV of the Securities and Futures Ordinance (SFO): directors, chief executives and any person interested in 5% or more of the Company’s issued voting shares must be disclosed. As at 31 March 2026, per the Company’s FY2026 annual report, the Company had 803,280,000 shares in issue. The three “Controlling Shareholders” named in the Company’s 15 March 2016 deed of non-competition – Mr. Lau Wai Kwok (Chief Executive Officer and executive Director), Mr. Chu Siu Sum Alex (non-executive Director) and Mr. Wong Chu Kee Daniel (Chairman and non-executive Director) – were among the largest disclosed holders. Mr. Lau held 100,000,000 shares (12.4%) plus 2,000,000 underlying share options (0.2%); Mr. Chu held 226,890,000 shares (28.2%) plus 500,000 underlying options (0.1%) and a further 450,000,000 underlying shares (56.0%) through controlled corporations, linked to convertible bonds issued to ServiceOne Global Limited, which is itself 30%-owned by China Expert Systems Limited, a company in which Mr. Chu holds a 40% interest; and Mr. Wong held 53,300,000 shares (6.6%) plus 500,000 underlying options (0.1%). Other disclosed substantial shareholders (non-director, 5% or more) as at 31 March 2026 were Mr. Mok Chu Leung Terry (91,800,000 shares, 11.4%) and Mr. Cheung Nap Kai (89,760,000 shares, 11.2%); each shareholder’s spouse is separately deemed interested in the same shares under the SFO.

Ultimate beneficial ownership

No single individual is identified in the sources reviewed as holding, alone, a majority economic or voting interest in Expert Systems Holdings Limited, and no jurisdiction-specific or configured UBO percentage threshold was supplied for this profile. Mr. Chu Siu Sum Alex’s combined interest (28.2% of shares plus a further 56.0% of underlying shares, largely contingent on conversion of a bond held via ServiceOne Global Limited and China Expert Systems Limited) is the single largest disclosed interest, but it mixes current shares with contingent underlying shares rather than representing one confirmed beneficial-ownership percentage, so no calculated UBO figure is presented here.

Data availability

Shareholder disclosure for Expert Systems Holdings Limited is Full for holdings that cross the SFO’s 5% notification threshold, since it is a GEM-listed company subject to Part XV of the SFO; the complete register of members, which would show all shareholders regardless of size, is not publicly available. Zavia’s on-file registry data for this company contained only a generic description of Hong Kong Significant Controllers Register filing requirements and named no shareholder; that placeholder text has been superseded here by the Company’s own FY2026 annual report disclosures.

Directors and officers of Expert Systems Holdings Limited

Per the Company’s FY2026 annual report, Expert Systems Holdings Limited’s board comprised nine directors as at the report date: four executive Directors (Mr. Lau Wai Kwok, Chief Executive Officer, appointed a Director on 18 September 2015 and CEO/executive Director on 15 March 2016; Mr. Chan Kin Mei Stanley, appointed a Director on 25 November 2015 and redesignated from non-executive to executive Director on 8 November 2021; Ms. Lau Tsz Yan, appointed executive Director on 15 March 2016; and Mr. So Cheuk Wah Benton, appointed executive Director on 15 March 2016); two non-executive Directors (Mr. Wong Chu Kee Daniel, Chairman, appointed a Director on 18 September 2015 and Chairman/non-executive Director on 15 March 2016; and Mr. Chu Siu Sum Alex, appointed 15 March 2016); and three independent non-executive Directors, each appointed 15 March 2016 (Mr. Au Yu Chiu Steven, Mr. Ko Man Fu and Mr. Mak Wai Sing). The Company’s external company secretary is Mr. Lau Siu Ki of Hin Yan Consultants Limited, and its chief financial officer, a senior-management (non-director) role, is Ms. Yung Pik Man, who joined in August 2023. No resigned or removed director is recorded in the FY2026 annual report; all nine are described as active. Nationality is not disclosed for any director or officer in the annual report, which sets out only their places of study and professional qualifications – this is standard practice for GEM-listed company disclosure and should not be inferred from any name, address or place of education shown.

Data availability

Officer disclosure for Expert Systems Holdings Limited is Full for its current board and named senior management, which are set out with appointment dates in the Company’s annual report and corporate governance filings; historical (resigned or removed) officers before FY2026 are not covered by this review. Zavia’s on-file officer register for this company listed only 5 of a stated 7 total officer records, gave no appointment or resignation dates for any of them, and used identical job-title text (“General Sales Manager Of Outside Sales Department & Executive Director”) for two different people, Ms. Lau Tsz Yan and Mr. So Cheuk Wah; the Company’s own annual report shows these two hold distinct roles (general manager of Expert Systems Limited, and sales director for the public-sector business unit, respectively). The on-file register also omitted four of the nine current directors entirely (the Chairman and all three independent non-executive Directors), and the company secretary’s on-file record carried the professional-qualification suffix “Fcca, Fcpa” concatenated into the surname field (“Siu Ki Lau Fcca, Fcpa”) rather than held as a separate field. These are flagged here as on-file data-quality issues rather than silently corrected in the registry.
