Giant makes frames for the bigger brands too. Trek, Scott and Colnago for example. Specialized doesn't make any of their own frames, as far as I know.
One of the reasons I bought a Giant is because of their excellent reputation for carbon construction, bottom brackets, dropouts, internal cabling etc. Giants are known to be no-nonsense bikes with excellent engineering.
