There is always a choice of classical IPv6 or geotop addressing.

Well, to start with if the company has a /32 then you are
talking about classic v6 addressing not geotop addressing.
A company that has geotop addresses will only receive an
allocation that is sized according to their needs in one
metro area. If they want to expand to other metro areas,
their allocation will not be big enough. The logical course
of action is to apply for allocations in the other metro 
areas.

I can't understand the benefits to a company of having a
single prefix as opposed to half a dozen. It's all inside
their own network anyway.
