Analysis · APAM · Finance
Artisan Partners reported an increase in its total Assets Under Management (AUM) for May. However, this positive was tempered by the disclosure of a significant $5.7 billion sub-advisory mandate termination expected in early June. While the company stated the revenue impact would be muted, such a large client outflow is a notable event for an asset manager, especially following previous reports of net client outflows in the first quarter.
