TST Group Holding Ltd. is listed on the Taiwan Stock Exchange (stock code 4439), so there is no publicly searchable shareholder register; major-holder information is published through Taiwan’s Market Observation Post System and the annual report. The shareholder schedule in the FY2024 audited consolidated financial statements lists the following holders of 5% or more, based on Taiwan Depository & Clearing Corporation data as at 31 December 2024:
- Xingmao Group Holdings Limited — 12,768,000 shares — 33.35%
- Big Loyal Group Limited — 2,484,000 shares — 6.48%

- Yuanta Commercial Bank as custodian for the Shun Heng Ltd. investment account — 2,208,000 shares — 5.76%
Xingmao Group Holdings Limited is also the corporate chairman of the board (represented by Lin Chin-Mao), indicating that the company is controlled by the Lin family through that holding vehicle; Lin Chin-Mao’s direct 6.40% is in addition to the Xingmao stake. The emerging-markets index funds and ETFs recorded elsewhere for this company are portfolio positions held by third-party asset managers and do not represent a controlling interest. No ultimate-beneficial-ownership statement is on the public record at the Cayman level.
Data availability: partial — Cayman Islands law does not require a public shareholder register; Taiwan disclosure covers holders above 5% and registered insiders as at each quarter-end.

Board and management as recorded on the company registry card and in the FY2024 audited consolidated financial statements (signed 12 March 2025):
- Chairman & President — Chin-Mao Lin (林錦茂). The chair of record is the corporate entity Xingmao Group Holdings Limited, for which Lin Chin-Mao acts as representative.

The surname Lin recurs — Chin-Mao Lin as chair and representative of the controlling holding company, and Ching-Wei Lin as general manager — which is consistent with a family-controlled board, given that Xingmao Group Holdings Limited is both the chair of record and the 33.35% controlling shareholder. Appointment dates are not stated in the sources reviewed, and no board changes were identified. Nationalities are not officially disclosed; the “address country” values on file (KY, BE, TW) are correspondence-address indicators only and are not evidence of nationality or residence.
Data availability: Cayman Islands company law does not require public disclosure of directors’ personal particulars, and Taiwan issuer disclosure does not generally publish director nationality. The above reflects the registry card and the most recent audited financial statements; the FY2025 annual report was not reviewed for this profile.
