Artisan Partners to Close US Value Team After $5.7 Billion Mandate Exit
Platform Contraction
Company Background
Artisan Partners Asset Management is a Milwaukee-based multi-asset investment firm managing $183.4 billion in assets across thirteen autonomous investment teams. Founded in 1994, the firm operates a decentralized model in which portfolio managers run independent investment franchises covering equities, fixed income, and alternatives, with strategies distributed through institutional separate accounts and Artisan-branded mutual funds.
Artisan has been navigating persistent outflows from its equity franchises alongside deliberate growth in credit and alternatives. Full-year 2025 revenues reached $1.2 billion, and first-quarter 2026 revenues of $303 million were 9% higher than the prior-year period. Management acknowledged in the Q1 2026 earnings release that 'pressure on equity flows' was expected to persist, citing clients de-risking, reallocating after periods of outperformance, and shifting to passive alternatives. The firm closed its acquisition of Grandview Property Partners, a private real estate manager with approximately $940 million in AUM, in January 2026.
The US Value team was one of Artisan's longer-tenured franchises, managing three equity strategies — Value Equity (inception July 2005), U.S. Mid-Cap Value (inception April 1999), and the much smaller Value Income (inception March 2022) — predominantly through separate accounts. At March 31, 2026, the team's combined AUM stood at approximately $7.5 billion.
What Was Disclosed
The termination of a U.S. sub-advisory mandate in June 2026 produced approximately $5.7 billion in net outflows from the Value Equity strategy. As a direct result, Artisan has commenced an orderly wind-down of all US Value team strategies, with the process expected to continue throughout the third quarter of 2026. The disclosure appeared as footnote 3 attached to the US Value team row in the AUM strategy breakdown table of a routine monthly preliminary AUM press release.
At June 30, 2026, the US Value team's three strategies collectively held approximately $1.8 billion in AUM: Value Equity at $473 million, U.S. Mid-Cap Value at $1.298 billion, and Value Income at $8 million — down from a combined $7.5 billion at March 31, 2026. All of this remaining AUM is in wind-down. Firm-wide preliminary AUM as of June 30, 2026, totaled $183.4 billion, roughly flat from $183.0 billion at April 30, 2026, with market appreciation across the broader platform absorbing the impact of the Value Equity outflow in the headline figure.
The filing contains no disclosure regarding personnel changes at the US Value team, the identity of the sub-advisory client whose mandate was terminated, or any restructuring charges expected in connection with the wind-down.
Why It Matters
Closing an entire named investment team — not merely losing a client — is an uncommon event for a publicly traded asset manager and represents a structural reduction in Artisan's platform. The US Value team's strategies held $7.5 billion at March 31, 2026, and the sub-advisory mandate, at approximately $5.7 billion, appears to have been the anchor relationship that made the Value Equity strategy commercially viable as a standalone offering; its departure left a $473 million residual insufficient to sustain ongoing operations. The wind-down covers all three US Value strategies, not just Value Equity.
Artisan's Q1 2026 earnings already flagged 'pressure on equity flows' as a persistent theme, and full-year 2025 saw $12.7 billion in net outflows firmwide. The US Value team's wind-down removes a further revenue-generating asset pool and compresses the equity platform at a moment when Artisan is actively expanding in credit and alternatives to compensate for equity attrition. The Q2 2026 earnings release, which will reflect the first full quarter impacted by the mandate termination and the onset of wind-down, will be the first opportunity to quantify any associated revenue and cost effects.
The firm's headline AUM of $183.4 billion — roughly flat with prior months — does not reflect the team closure in isolation, as broad market appreciation across other strategies offset the outflow. Investors relying solely on the aggregate AUM figure would not encounter the US Value wind-down without reading the footnotes to the strategy-level table.
