Consolidated company (4)
I believe the answer is:
firm
I believe this is a double definition.
'consolidated' is the first definition.
(thesaurus)
'company' is the second definition.
(firm can mean a company or business)
(Other definitions for firm that I've seen before include "Company - solid" , "Resistant to pressure" , "Unflinching" , "corporation?" , "Well-established - business" .)
