Artisan Partners Asset Management Inc. (NYSE: APAM) reported preliminary assets under management (AUM) of $183.5 billion as of August 31, 2026. The Milwaukee-based firm disclosed that a long-standing sub-advisory client is diversifying its mandate, which will trigger a $6 billion rebalancing from the Global Value strategy in September 2026.

The shift moves the client from a single-manager to a multi-manager structure. Artisan will remain one of three managers under the new arrangement. The company stated that the anticipated impact on revenues will be less than the corresponding reduction in AUM, given the specific fee structure associated with this mandate.

AUM Composition by Strategy

Total firm AUM was split between Artisan Funds and Artisan Global Funds, which accounted for $94.5 billion, and separate accounts and other AUM, which held $89.0 billion. Separate account and other AUM includes assets managed in traditional separate accounts, Artisan-branded collective investment trusts, and private funds.

The breakdown of AUM by investment team and strategy as of August 31, 2026, is detailed below:

What the Numbers Show

The data reveals a heavy concentration in value-oriented strategies. The International Value strategy alone holds $58.2 billion, representing approximately 31% of total firm AUM. When combined with the Global Value strategy ($39.96 billion), these two strategies account for nearly half of the firm's total assets. This concentration highlights the significant exposure to the upcoming $6 billion rebalancing, which specifically targets the Global Value strategy.

Additionally, the Credit Team manages $16.79 billion across four strategies, with the High Income strategy comprising the vast majority ($14.48 billion). This indicates that while equity strategies dominate the top line, credit represents a substantial and diversified asset class within the portfolio.

What the Numbers Show

The data indicates a heavy reliance on value strategies, with International Value and Global Value alone accounting for over $97 billion of the $183 billion total. This concentration suggests that client flows and market conditions affecting value investing will have a disproportionate impact on the firm's revenue base. Conversely, the U.S. Value Team is undergoing an orderly wind-down of its strategies, expected to continue throughout the third quarter, which may lead to further shifts in the portfolio composition.

The Antero Peak Group managed $2.513 billion in Antero Peak assets and $248 million in Antero Peak Hedge. These figures highlight the firm's diversified approach beyond traditional equity strategies.
