You could just hard-code this for your example, but you could also try to make it more general to deal with arbitrary numbers of companies and years, as in the code below.

Then, when this code is odd (as tested by company.numeric %% 2 == 1), we replace the Year values with a sequence of blank strings (if Year isn't already sorted, it needs to be sorted before doing this). # For every other Company, replace Year with …
