Shareholders of Maraen Fabrication Limited
Maraen Fabrication Limited has one disclosed shareholder, Maraen Holdings Limited (company number SC798197), which is also recorded as the company’s person with significant control, holding 100% of the issued ordinary share capital (1 ordinary share of GBP 1.00), per Companies House shareholder data verified 21 September 2026 and confirmed by a PSC filing notified 23 July 2025 recording ownership of more than 75% of shares and voting rights, with the right to appoint or remove directors. This shareholding replaced a previous 100% holding by Global Energy Fabrication Limited (company number SC310507), which ceased to be a person with significant control on 23 July 2025. The disclosure is complete: a single, wholly-owning corporate shareholder is identified, with no minority holdings reported.
Ultimate beneficial ownership
Maraen Holdings Limited is itself controlled by two corporate persons with significant control: Mitsui & Co. Europe Ltd (UK company number 02204039), recorded as holding more than 50% but less than 75% of shares and voting rights (notified 8 May 2025), and Mitsui O.S.K. Lines, Ltd, a Japan-incorporated entity recorded as holding more than 25% but not more than 50% of shares and voting rights (notified 31 July 2025). Mitsui & Co. Europe Ltd is in turn wholly owned (75% or more of shares and voting rights) by Mitsui & Co., Ltd., a Japanese trading company listed on the Tokyo Stock Exchange, as confirmed by Mitsui & Co. Europe Ltd’s own PSC filing (notified 6 April 2016). Because both ultimate corporate owners, Mitsui & Co., Ltd. and Mitsui O.S.K. Lines, Ltd., are publicly listed companies rather than natural persons, and the UK PSC register discloses only threshold ownership bands rather than exact percentages, no natural-person UBO or precise calculated effective ownership percentage can be determined from the available filings.
Data availability
Shareholder and PSC information for Maraen Fabrication Limited is classed as Full down to Maraen Holdings Limited, based on UK Companies House filings, and Partial beyond that point, since Mitsui & Co. Europe Ltd and Mitsui O.S.K. Lines, Ltd. are recorded only within statutory ownership bands rather than exact percentages.
