Compare and find the extra rows in two datarames with only one common column but different number of rows

I have two dataframes like this:

As you can see, df1 has more rows than df2. Only one column COMPANY is common to them. I want to find out the rows which are extra in df1, comparing only the COMPANY column of both dataframes (no other column can be compared).

Thanks in advance
