Each shareholder carries a Sophymarine OpenRegistry ID. Where the shareholder resolves unambiguously to a UK registered company the ID is openregistry-gb- plus its Companies House number, so the same company carries the same ID wherever it appears. Every other shareholder, including individuals, is given openregistry-h- plus the name as filed and a short hash of it.

A name-derived ID keys the name as recorded on the confirmation statement, not a verified individual. Two different people filed under the same name share one ID; one person filed inconsistently across companies receives more than one.

“% of class” is the holding as a proportion of the shares allotted in that class, from the statement of capital in the same filing. It is blank where the filing states no allotment for the class.

Not every UK company has a machine-readable shareholder list. 3,824 of the 14,276 companies in SIC 72190 do; companies without one are not listed here.
