If it is a corporation then it is a public entity, an institution of the state. It is not private.
Wrong. A corporation is not a "public" entity, even if shares can be bought by the public. A corporation is an entity separate from the state. A corporation's property is private property not public property.
A corporation is not necessarily an institution of the state. In fact, sounds like the corporation used the state to get it's way.
It is an entity recognized by the state. It is not an institution of the state.
Although it has many public requirements, it is a thoroughly private entity. In fact, in the eyes of the law, a corporation is viewed just as you and I are - as an individual entity.
