The Glen Welling-run activist investor, Engaged Capital, is planning a reshuffle at burger chain Shake Shack. A battle is on to gain three directors there, per The Wall Street Journal.

An activist investor buys a minority stake in a company, to gain its control, and to change how it’s run.

Engaged, which has a 6.6% stake in Shake Shack, has been in talks with the management for a restructuring.
