Getting to 1000 - the methodology

To build this list, Bureau van Dijk, which is a provider of Amadeus, a database of comparable financial information for public and private companies across Europe, combined key financial performance indicators of European companies.

Company status

Companies must be active, private and registered in the European Union (EU 28). Companies whose parent is incorporated in a foreign country are excluded. Public limited companies, Private limited companies and Partnerships entities are all considered. Investment vehicles and funds are excluded, as are charities and non-profit organisations. Companies whose Global Ultimate Owner is a Public authority, State, Government are excluded.

Size and age

Independent company or consolidated group revenues must be between €20m and €300m, based on latest filings. Companies that have been incorporated within the past four years are excluded (i.e. after 1 January 2013).

Financial performance

Each company’s compounded annual growth rate of the turnover is calculated over a three-year period (based on three sets of accounts for years 2013, 2014 and 2015). Any company with over 20% deterioration in net assets over the three-year period is excluded.

Country weighting

Having identified the long list, the eligible companies are then separated into their country of incorpora-tion. Within each country, the companies are ranked by their individual revenues compounded annual growth rate; and those that have most outperformed within their country are identified. The long list is split among the EU 28 countries according to every country’s contribution to the EU GDP.
