APAM reports $183.5 billion in AUM as of August 31, 2026 and expects a $6 billion Global Value rebalancing with a smaller relative impact on revenues.

Rhea-AI Filing Summary

Artisan Partners Asset Management Inc. (APAM) reported preliminary assets under management of $183.5 billion as of August 31, 2026. Artisan Funds and Artisan Global Funds represented $94.5 billion of AUM, while separate accounts and other AUM accounted for $89.0 billion. Total firm AUM includes $499.8 million managed through investment models provided to managed account sponsors.

The company disclosed that a long-standing sub-advisory client is shifting from a single-manager to a multi-manager structure. Artisan will remain one of three managers, but approximately $6 billion is expected to be rebalanced away from the Global Value strategy in September 2026. The anticipated impact on revenues is expected to be less than the corresponding reduction in AUM because of the mandate’s fee structure.

assets under management financial

"reported that its preliminary assets under management ("AUM") as of August 31, 2026"

Assets under management (AUM) is the total value of all the investments that a financial company or fund is responsible for overseeing on behalf of its clients. It’s like a big bucket that shows how much money the firm is managing for people or organizations. A higher AUM often indicates a larger, more trusted company, and it can influence how much money they earn and the services they can offer.

separate account financial

"Separate account and other AUM consists of the assets we manage"

A separate account is a pool of investments legally kept apart from a firm’s general assets and managed specifically for a particular client, group of clients, or an insurance contract — like a dedicated suitcase of investments instead of putting everything in one closet. It matters to investors because it determines who absorbs gains or losses, usually offers protection from the firm’s creditors, and can have different fees, liquidity and rules than the firm’s main asset pool.

sub-advisory client financial

"a long-standing sub-advisory client is diversifying our mandate"

NAV financial

"Represents NAV plus uncalled and recallable capital"

Net asset value (NAV) is the total value of all the investments and assets in a fund or company, minus any debts or liabilities, divided by the number of shares or units outstanding. It represents the per-share worth, giving investors an idea of what each share is truly worth based on the underlying assets. Think of it like a company's total worth divided among its shares, helping investors assess whether a share is fairly priced.

uncalled and recallable capital financial

"Represents NAV plus uncalled and recallable capital"
