Cats are solitary animals - especially males. They are very territorial, bond with the place they live first and foremost, their humans second and other species - especially their own- a very distance third.
Two kittens rehoused together will usually form a friendship - especially if they are litter mates. Unrelated cats of differing ages much less so. Oh, there won't be any overt aggression after a while, but they won't be friends, either. You won't see them lying together, grooming each other-THE sign of an affectionate, social bond in the cat world. They'll split the territory between them and tolerate each other. They'll rarely be in the same room together. They will choose a different human to socialise with so they can avoid each other. One cat will subtly dominate the other. The dominant cat will monopolise the food, the litter boxes, the cat flap, access to the other cats favoured resting places, things like that.
The upshot is your cat hit the jackpot! He is Lord and Master of all he surveys. No "companion" to threaten his territory inside, no competitors outside to threaten his all important sense of place and peace of mind either.
Your cat does not need a feline companion. Unlike dogs ( and us) cats are not a social species. So be reassured you're doing the right thing by your cat.
