The lawsuit recoups equity and cash in his severance payment valued at $105 million.
McDonalds says Easterbrook would not have received the payment if he’d been “truthful” about his misconduct.
The company fired him in November 2019 after an investigation found he had engaged in a consensual relationship with another employee in violation of company policy.
The fast-food giant sued Easterbrook in August 2020, after an internal investigation.
The company alleged he lied to investigators about his misconduct, including sexual relationships with multiple subordinates.
Easterbrook has apologised, saying he had failed to uphold McDonald’s values of “doing the right thing”.
