Artisan Partners reports $186.0B AUM in May 2026, facing $5.7B mandate termination

Artisan Partners Asset Management reported preliminary assets under management of $186.0 billion as of May 31, 2026, with notification of an expected $5.7 billion U.S. Value Equity sub-advisory mandate termination in early June. The company notes the revenue impact will be muted given the mandate's fee structure, though the asset outflow represents a notable reduction in managed assets.
