Outflow Trend Continues

Analysis · APAM · Finance
Artisan Partners disclosed August AUM of $183.5 billion, but the real news is a long-standing sub-advisory client restructuring its mandate from single-manager to multi-manager. That change is expected to trigger a rebalancing of roughly $6 billion out of the Global Value strategy in September 2026. The company says the revenue hit will be smaller than the AUM drop because of the mandate's fee structure, but this is still a material loss of assets at a time when the firm has already reported $10.5 billion in net outflows for Q2 2026 and is winding down its U.S. Value team. The filing confirms the outflow trend is continuing into the second half of the year.
