FAQ: Board Interlocks / Interlocking Directorates

by | Apr 17, 2026

What are Interlocking Directorates / Board Interlocks?

Board interlocks are where a person affiliated with one organization sits on the board of directors of another organization. For example, if a director sits on both the boards of Tesla (TSLA) and Ford (F) those boards and that director would be considered interlocked.

Why do Board Interlocks Matter?

Typically interlocking directorates are viewed as posing a potential risk of collusion or anticompetitive behavior. These risks rise significantly when officers and directors are serving simultaneously on the boards of competitors.

Are Board Interlocks Legal?

Section 8 of the Clayton Act (Section 8) prohibits directors and officers from serving simultaneously on the boards of competitors, subject to limited exceptions. 

On October 19, 2022, the Justice Department released a notice stating that it had required 7 directors across 10 interlocked companies to remove directors that created the interlock.

What Does Section 8 of the Clayton Act Say Regarding Interlocking Boards?

The section of the Clayton Antitrust Act prohibiting any person from simultaneously serving as an officer or on the board of directors of competing corporations (known as an interlocking directorate or interlock). Section 8 prohibits interlocks if the corporations are engaged in commerce and have capital, surplus, and profits exceeding certain thresholds, as revised annually by the Federal Trade Commission. Certain safe harbors and exemptions apply to Section 8, including based on the degree of competition between the corporations.
