Following previous Clayton Act enforcement efforts prohibiting interlocking directorates, the Department of Justice (“DOJ”) announced on Thursday, March 9, 2023, that five directors have resigned from overlapping board positions, and one company declined to exercise its board appointment rights. This marks the second wave of resignations since DOJ increased its scrutiny of interlocking directorates, bringing the total number of unwound or prevented interlocks to at least 13 directors across ten boards in less than six months.
