The recession of 1981-1982 and a change in contractors midway through the project that led to cost overruns resulted in the completion of only one tower instead of the initially planned three.

A plaza with trees and landscaping now occupies the land on which the other towers were to have been built, and is home to food trucks, community events, and farmer's markets.

Through a succession of mergers, One Summit Square eventually became the Northeast Indiana market headquarters for JPMorgan Chase.

However, Chase Private Client was made available at this branch in 2020, tapping into the rise of the affluent locating downtown; the 2016 renovation allowed for this to be added.

As a result of these changes, One Summit Square was renamed Indiana Michigan Power Center with added signage on the west and east facades of the building.
