Previous wording

Our profitability is affected by a variety of factors including the level and composition of our average assets under management, or AUM, fee rates charged on AUM and our expense structure. We earn management fees based on assets under management. The majority of our management fees are calculated based on average AUM (calculated on either a daily or monthly basis) with the remainder of our management fees calculated based on period-end AUM. Changes in the levels of our AUM are driven by market investment performance and net client cash flows. We may also earn performance fees when certain accounts differ in relation to relevant benchmarks or exceed required returns. As of June 30, 2026, approximately $28 billion, or 12%, of our AUM was in accounts with incentive fee features in which we participate in the performance fee. The majority of these performance fees are calculated based on value added over the relevant benchmarks on a rolling one-year basis.

The increase was primarily attributable to higher pre-bonus profits in the three months ended June 30, 2026, including changes in deferred bonus earned on performance fee revenues in the three months ended June 30, 2026. The deferred nature of the bonus earned on performance fee revenues can result in compensation expense variability that is uncorrelated to current period earnings.

Acadian LLC key employee distributions for certain tiers of equity are calculated after an earnings threshold is met, whereby no distributions are made to these equity holders when earnings are below the threshold. The change in Acadian LLC key employee distributions during the current period is driven by higher operating earnings in the current period and the leveraged nature of this distribution share. Revaluations of Acadian LLC key employee equity changed by $13.6 million, reflecting an increase in the value of key employee ownership interests at Acadian LLC.

Sales-based compensation increased $4.9 million, or 144.1%, from $3.4 million for the three months ended September 30, 2025 to $8.3 million for the three months ended September 30, 2026, driven by the timing of asset inflows in the last 12 months. Variable compensation increased $7.1 million, or 22.3%, from $31.8 million for the three months ended September 30, 2025 to $38.9 million for the three months ended September 30, 2026. The increase was primarily attributable to higher pre-bonus profits in the three months ended September 30, 2026, partially offset by changes in deferred compensation expense in the three months ended September 30, 2026.
