Google Sheets highlighting based on list of words

I have 2 columns A & B

A has a list of 100 names of companies

B has a list of 10 companies

What custom formula formula can I use to ensure all companies from Column B will be highlighted in Column A (if they are found)?

countif()
providing the names are identical

countif($B$2:$B$11,A2)>0
based on the names being in cells B2 to B11
and the names in A starting at A2
