Shareholders of Surface Technology International Limited
Surface Technology International Limited is a UK private company, so shareholder disclosure follows the statutory persons-with-significant-control (PSC) regime rather than a published share register. As of the latest Companies House filing (notified 17 December 2025), the registered controlling entity is STI Enterprises Holdings Limited (company number 15016822, England), holding more than 75% of shares and voting rights and the right to appoint or remove a majority of directors. This is a corporate PSC (a registrable relevant legal entity), not a natural person.
Before that date, from 6 April 2016 to 17 December 2025, the equivalent controlling interest (75%+ shares and voting rights) was held by STI Enterprises Limited (company number 07616264), which was subsequently renamed Clifton 2025 Limited on 19 January 2026 as part of the same group reorganisation. Cached share-register data (125,000 Ordinary shares plus small allotments of Ordinary B, D, E and F shares held by "STI Enterprises Limited") reflects this earlier position and predates the December 2025 restructuring, so it should be treated as historical rather than current.
Ultimate beneficial ownership
No natural person is currently registered as a PSC of Surface Technology International Limited directly; the disclosed controller is a corporate entity. Tracing the ownership chain through each entity’s own PSC filing: STI Enterprises Holdings Limited is itself controlled by Note UK Holding Limited (company number 05257074, England), notified as PSC on 19 March 2026 with more than 75% of shares and voting rights. Note UK Holding Limited is in turn controlled by Note AB (publ) (Swedish registration number 556408-8770), notified as PSC on 1 June 2016. Note AB (publ) is a company listed on Nasdaq Stockholm.
This indicates Note AB (publ), a publicly listed Swedish electronics manufacturing services group, sits at the top of the disclosed ownership chain identified through official filings. Because UK and Swedish PSC disclosures use control bands (e.g. "75% or more") rather than exact percentages, a precise calculated effective ownership percentage cannot be derived; no further individual natural-person UBO is disclosed within the scope verified.
Data availability
Availability is best described as "major shareholders only": the UK PSC register discloses controllers above statutory thresholds in control bands, not a full shareholder list or exact percentages, so granular holding percentages for the corporate PSCs identified are not published.

Group Structure
Group structure of Surface Technology International Limited
Surface Technology International Limited is part of a verified corporate group rather than an independent company. Its immediate parent, verified via the company’s own persons-with-significant-control filing, is STI Enterprises Holdings Limited (company number 15016822, England, active, a holding company registered at the same address as the target), which holds more than 75% of shares and voting rights and the right to appoint or remove directors, notified 17 December 2025. Tracing the chain through each entity’s own filing identifies Note AB (publ), a Nasdaq Stockholm-listed Swedish electronics manufacturing services group, as the ultimate identified parent. One historical subsidiary relationship was verified; no currently active subsidiaries of the target were identified. Information below is current as of the retrieval date.

Unverified aggregator data linking the target to a broad portfolio of unrelated companies associated with the name "RCapital Limited" was reviewed but could not be confirmed via any of those entities’ own Companies House filings, and has been excluded as a possible relationship rather than presented as verified.
Recent structural changes
- 17 December 2025: Group reorganisation — registered control of Surface Technology International Limited transferred from STI Enterprises Limited (since renamed Clifton 2025 Limited) to newly interposed STI Enterprises Holdings Limited; on the same date, control of former subsidiary STI Poynton Limited passed out of the group.
- 19 March 2026: Note UK Holding Limited registered as PSC of STI Enterprises Holdings Limited, replacing the previous individual and corporate controllers.
- 21 July 2026: Former subsidiary STI Poynton Limited, by then renamed Hertford 2023 Limited, was dissolved.
Data availability
Full for the verified upward ownership chain, based on each entity’s own PSC filing. Partial for subsidiaries: UK PSC disclosure publishes registrable controllers of a company, not a complete downward list of its own subsidiaries, so beyond the one historical relationship identified, further subsidiaries of Surface Technology International Limited (if any) cannot be confirmed from this source alone.
