It looks like it is owned by Wells Fargo Bank, N.A. But it's a bank, so I'm not sure about the word "owned."
"Wells Fargo in its present form is a result of a merger between San Francisco-based Wells Fargo & Company and Minneapolis-based Norwest Corporation in 1998 and the subsequent 2008 acquisition of Charlotte-based Wachovia. Although Norwest was technically the surviving entity in the 1998 merger, the new company renamed itself Wells Fargo, capitalizing on the 150-year history of the nationally recognized name and its trademark stagecoach. Following the acquisition, the company transferred its headquarters to Wells Fargo's headquarters in San Francisco and merged its operating subsidiary with Wells Fargo's operating subsidiary in Sioux Falls.
...The firm's primary U.S. operating subsidiary is national bank Wells Fargo Bank, N.A., which designates its main office as Sioux Falls, South Dakota. "
