Shareholders of GEM Services, Inc.
The on-file registry snapshot for GEM Services, Inc., verified 2 August 2026, lists ten shareholder records, of which the five largest disclosed are all institutional funds rather than natural persons: DFA Emerging Markets Core Equity Portfolio (reported holding 453,970 ordinary shares, 22.57%), Financial Investors Trust – Grandeur Peak Global Reach Fund (166,000 shares, 8.25%), SPDR (R) Index Shares – SPDR (R) Emerging Markets Small Cap ETF (25,879 shares, 1.29%), Dimensional ETF Trust – Dimensional World ex U.S. Core Equity 2 ETF (24,200 shares, 1.20%) and DFA Investment Dimensions – Emerging Markets Social Core Equity (23,670 shares, 1.18%). These holdings are consistent with the kind of foreign institutional portfolio investment commonly seen in Taiwan Stock Exchange-listed shares. Separately, market-data providers reporting on GEM Services, Inc.’s Taiwan Stock Exchange filings describe Elite Advanced Laser Corporation (TWSE: 3450) as holding a majority stake of around 51% (about 65.8 million shares); that holding does not appear in the on-file registry snapshot, indicating the on-file list captures only a subset of the full shareholder base rather than the complete register.
Data availability
Shareholder disclosure for GEM Services, Inc. is best described as Partial: the available on-file snapshot lists only minority institutional holders as of 2 August 2026 and omits the reported majority shareholder entirely, and the Cayman Islands General Registry does not itself publish a private company’s full shareholder register, so this profile relies on a mix of internal registry data and external Taiwan Stock Exchange-linked reporting of uneven reliability.

These correspondence-country fields describe only where official communications are addressed; they are not evidence of any officer’s nationality or country of residence, and nationality is not disclosed for any of the three in the source reviewed. Names and titles matching Yen-Chiang Tang and Jui-Ping Wang appear independently in third-party financial data profiles of the same Taiwan Stock Exchange-listed company, which is one of the identifiers used to confirm this profile concerns the correct GEM Services, Inc. Separately, the company’s own investor-relations pages describe a nine-member board of directors, including a chairman, a vice chairman, three further directors and four independent directors, which is not reflected in the on-file officer list above.
Data availability

Group Structure
Group structure of GEM Services, Inc.
The on-file registry record for GEM Services, Inc. reports no parent, subsidiary or ownership linkage in that particular source. External research using the company’s own published materials tells a more complete story. GEM Services, Inc.’s own corporate timeline states that Elite Advanced Laser Corporation, a company listed on the Taiwan Stock Exchange (ticker 3450), became its largest shareholder in June 2012 following a cash capital increase; third-party financial data providers tracking GEM Services, Inc.’s Taiwan Stock Exchange filings describe this stake as currently around 51%, though that precise percentage was not independently confirmed from a primary regulatory filing during this review. The same corporate timeline identifies two direct operating subsidiaries in mainland China, GEM Electronics (Shanghai) Co., Ltd. (established 1998) and GEM Electronics (Hefei) Co., Ltd. (established 2006), plus a further entity, GEM Tech Limited, founded in 2012; none of these carry a disclosed registration number or ownership percentage in the sources reviewed.

Data availability
Corporate-linkage information for GEM Services, Inc. is Partial: the underlying registry source used for this profile discloses no group structure at all, which is typical for the largely non-public Cayman Islands company registry, while the company’s own published corporate history discloses an immediate parent and several operating entities without registration numbers or confirmed ownership percentages. This should not be read as a complete or independently verified picture of the group.

What was GEM Services, Inc.'s most recently reported revenue?
Market-data services tracking GEM Services, Inc.'s Taiwan Stock Exchange filings reported full-year 2025 revenue of approximately NT$5.33 billion; this figure comes from third-party financial reporting rather than a primary annual-report filing reviewed directly for this profile.
Who are GEM Services, Inc.'s officers?
The on-file record lists three active officers: Yen-chiang Tang (President & GM), Anthony Chia (Chief Operations Officer) and Jui-ping Wang (Head of Finance & Accounting). No appointment dates, resignation dates or nationalities are disclosed in that record.
Who owns GEM Services, Inc.?
A registry snapshot verified 2 August 2026 lists ten shareholder records, the largest disclosed being institutional investment funds; that snapshot appears to be a partial list, since it does not include Elite Advanced Laser Corporation, which third-party financial data providers describe as holding a majority stake of around 51% since 2012.
Does GEM Services, Inc. have a parent company?
GEM Services, Inc.'s own published corporate timeline states that Elite Advanced Laser Corporation (Taiwan Stock Exchange ticker 3450) became its largest shareholder in June 2012 through a cash capital increase; the current percentage reported by third-party data providers (around 51%) was not independently confirmed from a primary regulatory filing during this review.
What subsidiaries does GEM Services, Inc. have?
According to the company's own corporate timeline, its group includes GEM Electronics (Shanghai) Co., Ltd. (established 1998), GEM Electronics (Hefei) Co., Ltd. (established 2006) and GEM Tech Limited (founded 2012); none of these carry a disclosed registration number or ownership percentage in the sources reviewed.
Why is confirming the identity of this Cayman Islands "GEM Services, Inc." difficult?
"GEM Services" is a fairly generic name, and no registration number, incorporation date or website was recorded on file, which is a high-risk situation for confusing this entity with an unrelated company, including various unrelated "GEM"-branded investment or finance entities. A confident match was reached only by cross-checking multiple independent identifiers together: the on-file registered postal code (KY1-1106, Grand Cayman) matches the address reported by an independent financial data source; the on-file officers' names and job titles (Yen-chiang Tang as President & GM, Jui-ping Wang in finance) match officers reported for the specific Taiwan Stock Exchange-listed company trading as ticker 6525 with ISIN KYG3790U1040; and the Cayman Islands (KY) jurisdiction embedded in that ISIN is consistent with the on-file jurisdiction. No Cayman Islands General Registry extract or SEC or court filing naming this exact entity was located, since the Cayman Islands company registry is not public for private companies, so this match rests on convergent circumstantial identifiers rather than a single authoritative document.
Has GEM Services, Inc. had any recent changes to its ownership, leadership or corporate structure?
No independently verified recent change was identified during this review. The most recent structural change found in the company's own published history is Elite Advanced Laser Corporation becoming its largest shareholder in June 2012, and no more recent acquisition, disposal or leadership change could be confirmed from the sources reviewed.
