Group accounts
The company is registered as part of a group, but we have no group accounts for it. Group accounts are filed by the parent company, and open data does not say which company that is.
Read the figures with care: a company in a group can look strong because of group contributions, or weak because dividends go up to the parent. The figures are indications, not the full picture.
We do not show the group structure, because open data does not say who owns whom.
