CARTERTON INVESTMENTS LIMITED
Carterton Investments Limited is a private limited company registered in Ireland under company number 38050, incorporated on 25 July 1972. The Companies Registration Office (CRO) lists the company’s status as active, with its most recent annual return and accounts filed on 19 June 2026 for the financial year ended 30 December 2025.
The company’s registered address is Mercury Global Headquarters, Ballycoolin Business Park, Blanchardstown, Dublin, D15 PD87. Its registered principal activity is classified as “management activities of holding companies” (SIC/NACE 74.15), and CRO business-name filings show it trading as Mercury Group and Mercury Sprinkler Systems. This classification and the trading names indicate that Carterton Investments Limited functions as an internal holding entity within the privately held Mercury group, an Irish-founded engineering, building-services and construction-contracting business, rather than as a company trading independently with an external customer base of its own.
No stock-exchange listing has been identified for Carterton Investments Limited, and no standalone revenue or employee figures are publicly reported for the entity separately from the wider Mercury group.

Shareholders of Carterton Investments Limited
Registry-sourced shareholder data places Carterton Investments Limited’s issued share capital with three corporate shareholders, as at 31 December 2024. Mercury Holdings Unlimited Company (Irish company number 455648, formerly registered as Mercury Holdings Limited) holds 99,413 ordinary shares of EUR 1.30 each, equal to approximately 99.90% of issued capital, making it the company’s overwhelming majority shareholder. Mercury Engineering Unlimited Company holds 100 Ordinary “A” shares (approximately 0.10%), and Mercury Investments Unlimited holds a single ordinary share (a nominal holding of roughly 0.001%). All three disclosed shareholders are themselves Irish-registered companies within the same corporate family; no natural-person shareholder appears on the share register.
An independent commercial company-information search corroborates Mercury Holdings as the company’s principal shareholder, though it records the name in its earlier form, “Mercury Holdings Limited” – consistent with the entity’s later conversion to unlimited-company (ULC) status under the same CRO registration number, 455648.
Data availability
Shareholder disclosure for Irish private companies covers the statutory share register but not a separately searchable beneficial-ownership register. The holding percentages above reflect a shareholder-register snapshot dated 31 December 2024; no natural-person ultimate beneficial owner could be independently verified from public sources, so this profile does not present a UBO determination. Availability is assessed as Major shareholders only.

Group Structure
Group structure of Carterton Investments Limited
Carterton Investments Limited is not an independent company. Registry and shareholder data confirm it is a majority-owned subsidiary of Mercury Holdings Unlimited Company (Irish company number 455648, previously registered as Mercury Holdings Limited), which an independent company-information search corroborates as an active Irish holding company. This is the only parent relationship independently verified for this profile as at 24 September 2026.
Corporate-linkage data associated with this profile additionally places Mercury Holdings within a wider, privately held international group headed by a UK-registered entity, alongside further Mercury-branded engineering, building-services and international-services companies operating across countries including the Netherlands, Austria, Germany, Poland, Sweden, Denmark, Finland, Turkey, Italy, Spain, Portugal and Switzerland. This wider structure could not be independently corroborated entity-by-entity from primary company registries within this research and is presented as a possible relationship rather than a verified one.
