Officials at these universities will gladly talk about any research that has become public; they like to toot their own horns. They will reference private research - $100 million in cancer research, e.g.. Unless, however, private research has become - somehow - public, they will not talk about it.
They will not discuss details of private research. I have never worked in North Carolina, but I assume that officials in that state are bound by the same laws and ethics that govern the rest of the country.
As for alumni association people, they are also bound by guidelines and laws, but do whatever is in their interests. They release annual reports. These reports include numbers, but details are not often offered to the general public.
