You can easily search a specific company using the 'Company Search' field. When you have a value in this field, the screener will ignore all other filters. When you start typing the name of a company, a list of options will show up. You can select a company from the list
After selecting the company it will show up in the screener grid if the company has its primary listing in a country that is covered by your subscription. If this is not the case the screener grid will be empty.
