The Globe and Mail reports in its Wednesday edition that for 15 years, brothers Chris and Phil Mittleman worked amicably together as partners at Mittleman Investment Management, but once they gained control of investment firm Aimia in 2020, however, their relationship was quickly torn apart. The Globe's Jameson Berkow writes that Chris was fired as the company's chief investment officer in March, 2023, just weeks before Phil -- the chief executive officer -- narrowly survived an attempt by Aimia's largest shareholder to oust the entire board. Now, the two brothers are locked in a dramatic litigation against each other, with the future of Aimia at stake. Phil claims his older brother engaged in an "unlawful conspiracy" with dissident shareholders to take over the company, according to his statement of claim. Chris, in a counterclaim and statement of defence filed with the Ontario Superior Court of Justice, calls the case brought against him an act of "oppression, fraud" and "retribution." He is seeking to be reinstated as a member of Aimia's board and to have Phil removed. He also wants damages of $5-million (U.S.). "Phil was enabled by a careless board, stacked with neophytes and cronies," the counterclaim alleges.
