Walmart is or was a family controlled multinational retail corporation, it is one of the largest public corporations on earth and one of the biggest private employer. If what wren says is true then Walmart may be much more than what it was originally by the time of Alien: Resurrection.

Alien: ResurrectionEdit

Walmart is the corporation which bought out Weyland-Yutani sometime in the late twenty-fourth century following the financial difficulties Weyland-Yutani experienced as a result of the events on Acheron (LV-426) in 2179. Some believe that Dr. Wren was lying to Ripley about the "Walmart buyout" in order to keep her compliant considering the ramifications of such information. This would suggest that the USM is simply just another branch of Weyland Yutani at the time.
