Amidst growing federal and state scrutiny of proxy advisory firms, the U.S. Department of Justice’s Antitrust Division (the “Division”) recently entered the fray. On August 5, 2026, the Division withdrew its 1987 business review letter (the “Letter”) to proxy advisory firm Institutional Shareholder Services Inc. (ISS), stating that the Letter no longer reflects ISS’s current business practices and citing concerns about concentration among proxy advisors.
The Division’s decision to withdraw the Letter is not an enforcement action or a finding that ISS violated the antitrust laws. In fact, the Division emphasized that proxy advising is not inherently problematic and that voting based on a proxy advisor’s recommendation does not by itself raise competition concerns. However, the Division’s decision signals that proxy advisors like ISS, and perhaps the broader asset management industry, may face increased scrutiny, especially during next year’s proxy season.
