Artisan Partners Asset Management Inc. Reports May 2026 Assets Under Management

Milwaukee, WI - June 05, 2026 - Artisan Partners Asset Management Inc. (NYSE: APAM) today reported that its preliminary assets under management ("AUM") as of May 31, 2026 totaled $186.0 billion. Artisan Funds and Artisan Global Funds accounted for $92.3 billion of total firm AUM, while separate accounts and other AUM1 accounted for $93.7 billion. During the period, Artisan was notified that a U.S. sub-advisory mandate representing approximately $5.7 billion of assets in the U.S. Value Team’s Value Equity strategy is expected to terminate in early June 2026. The reduction in assets under management will have a muted impact on revenues given the nature of the mandate and its associated fees.
