County
Number of companiesActivity codes included
This industry gathers the following SN2007 activity codes. Each code also has its own overview page.
About the figures
Figures are the latest annual accounts filed with the Register of Company Accounts, matched to the activity code the company carries in the Central Coordinating Register. A company lands in an industry on the strength of that registered code, not an assessment of what it actually does.
The operating-margin list and the median use only the 1 343 companies with at least 5 employees and over 5 mill. kr in revenue, so a small company with erratic figures cannot top the list.
4 companies are held out because their operating margin exceeds 75% – far above the norm for this industry. That is almost always a wrong activity code or fair-value gains booked as operating revenue, not trading.
