Financials
Values in EUR as filed in the published annual reports.
PRH publishes machine-readable accounts only for companies that filed them electronically — about 2.7% of the trade register. These figures are therefore partial: they cover the accounting periods that could be read, not every set of accounts the company has filed.

Income tax, as assessed
Public income tax data published by the Finnish Tax Administration. Taxable income is not revenue and not profit: it is the amount the tax was assessed on, after every deduction and loss carried forward. A large company can legitimately show zero.

Verification
How much of the public record we hold. It describes our data, not the company — a young company with one filing is not risky for having one filing.
- Name and Business ID
- Registered address
- Legal form
- Business activity
- VAT number verified in VIES
- Board and officers

- Three or more periods

What the filings say
- The most recent period (2025) closed at a loss.
This is not a credit rating. It draws only on public registers — we hold no payment history, no court records and no bank data. Every signal names the year and the figure it came from so it can be checked. EquityNet profit

Underlined ones lead to the other companies registered for the same activity. The rest are too specific — tied to a single licence, say — to have a page of their own.

A responsible-person notice records only that responsible-person or signatory details were amended. PRH's open data contains no personal names, so none are published here.
A trade-register notice records what kind of filing was registered and when — not which value changed, or what it changed to. Any value shown beside an event comes from the register's own data fields, not from the notice.
The notice history covers filings registered from 7 November 2014 onwards. Earlier register entries appear only where the register publishes their dates.
