“American Glass Research has now been identified as partially-owned by BlackRock investments, and whose Executives are formerly with Pfizer.”
Identified by whom as partially owned by Blackrock?
It would be unusual for AGR to “own” that building. It is almost never a good idea for a company that size to own, rather than lease. Blackrock owns commercial properties all over the world.
If the original owners wanted to sell and they had long term leases with sound companies…buying that kind of commercial property is perfect for a large real estate company. This is especially true if there are several of them within a small footprint so you can centralize/consolidate the maintenance for the properties.
