Artisan added $10.4 billion to its assets under management in the quarter, a pile of money roughly four times the firm's $2.6 billion market cap. On the surface that's an eye-catching scale move: revenue jumped to $307.9 million, operating income rose to $84.6 million, and diluted EPS climbed to $1.11, up 18% year over year.
The headline gain masks a pair of opposing receipts in the 10-Q.
"During the three months ended June 30, 2026, our AUM increased to $183.4 billion, an increase of $10.4 billion, or 6%, compared to $173.0 billion at March 31, 2026, primarily due to $21.2 billion of market appreciation, partially offset by $10.5 billion of net client cash outflows."

That line makes the pivot plain: most of the AUM gain came from market moves, not new client cash. Revenue can swell when market prices rise; it does not necessarily mean customers returned.
At the same time, employee pay ran up.
"Operating Expenses Compensation and Benefits For the Three Months Ended June 30, Period-to-Period 2026 2025 $ % (unaudited; in millions) ... Total compensation and benefits $ 182.0 $ 165.8 $ 16.2 10 % ... The increase in total compensation and benefits was primarily due to a $7.4 million increase in long-term incentive compensation largely driven by market valuation changes, a $4.5 million increase in incentive compensation primarily attributable to higher revenues and a $3.0 million increase in employee separation related costs including those associated with the wind down of the U.S."

Compensation increased in the period, and some of that increase was driven by market-valuation changes in long-term incentive awards.
Artisan turned a modest revenue bump into larger net income and operating cash flow improvements, but two dynamics warrant attention: AUM gains were largely market-driven while net client flows were negative, and compensation tied to those same market moves increased. The filing also shows non-operating investment gains actually fell by $17.6 million because invested balances averaged lower in the period, so the operating improvements had to carry the whole result.
Cash generation did improve: net cash provided by operating activities rose to $297.6 million for the six months, up $88.8 million from a year ago, helped by working-capital changes and higher operating income. This reflects improved cash generation, even as margin and flow composition raise questions.
Put another way: Artisan still runs the sort of margins that show up in the long-term numbers, operating margin was 33.4% in 2025, but this quarter's operating margin ticked down to 27.5% while net margin widened, reflecting a mix of timing, compensation, and non-operating items.
The next 10-Q will show whether AUM change for the coming quarter reflects positive net client flows or remains market-led.
Did clients come back, or did markets do the heavy lifting?
AUM rose to $183.4 billion, driven by $21.2 billion of market appreciation and $10.5 billion of net client cash outflows, filings show (10-Q, 2026-07-31).
