23 References to “Acadian Asset Management”, “Acadian”, “AAMI” or the “Company” refer to Acadian Asset Management Inc.; references to “Hold Co” refer to AAMI and its subsidiaries excluding Acadian Asset Management LLC (“Acadian LLC”). The Company currently operates its business through one asset management firm, Acadian LLC. The Company’s distribution activities are conducted in various jurisdictions through affiliated companies in accordance with local regulatory requirements.

The Company uses a non-GAAP performance measure referred to as economic net income (“ENI”) to represent its view of the underlying economic earnings of the business. ENI is used to make resource allocation decisions, determine appropriate levels of investment or dividend payout, manage balance sheet leverage, determine Acadian LLC variable compensation and equity distributions, and incentivize management. The Company’s ENI adjustments to U.S.

GAAP include both reclassifications of U.S. GAAP revenue and expense items, as well as adjustments to U.S. GAAP results, primarily to exclude non-cash, non-economic expenses, or to reflect cash benefits not recognized under U.S.

GAAP. The Company re-categorizes certain line items on the income statement to:

exclude the effect of Fund consolidation by removing the portion of Fund revenues, expenses and investment return which is not attributable to its shareholders;
include within management fee revenue any fees paid to Acadian by consolidated Funds;
treat sales-based compensation as a general and administrative expense, rather than part of fixed compensation and benefits; and
identify separately from operating expenses, variable compensation and Acadian LLC key employee distributions, which represent Acadian LLC earnings shared with Acadian LLC key employees. The Company also makes the following adjustments to U.S. GAAP results to more closely reflect its economic results by: i. excluding non-cash expenses representing changes in the value of Acadian LLC equity and profit interests held by Acadian LLC key employees. These ownership interests may in certain circumstances be repurchased by the Hold Co at a value based on a pre-determined fixed multiple of trailing earnings and as such this value is carried on the Company’s balance sheet as a liability. Non-cash movements in the value of this liability are treated as compensation expense under U.S. GAAP. However, any equity or profit interests repurchased by the Hold Co can be used to fund a portion of future variable compensation awards, resulting in savings in cash variable compensation that offset the negative cash effect of repurchasing the equity. ii. excluding non-cash amortization or impairment expenses related to acquired goodwill and other intangibles as these are non-cash charges that do not result in an outflow of tangible economic benefits from the business. iii. excluding capital transaction costs, including the costs of raising debt or equity, gains or losses realized as a result of redeeming debt or equity and direct incremental costs associated with acquisitions of businesses or assets. iv. excluding seed capital and co-investment gains, losses and related financing costs. The net returns on these investments are considered and presented separately from ENI because ENI is primarily a measure of the Company’s earnings from managing client assets, which therefore differs from earnings generated by its investments in Acadian LLC products, which can be variable from period to period. v. including cash tax benefits associated with deductions allowed for acquired intangibles and goodwill that may not be recognized or have timing differences compared to U.S. GAAP. vi. excluding the results of discontinued operations attributable to controlling interests since they are not part of the Company’s ongoing business, restructuring costs incurred in continuing operations. vii. excluding deferred tax resulting from changes in tax law and expiration of statutes, adjustments for uncertain tax positions, deferred tax attributable to intangible assets and other unusual items not related to current operating results to reflect ENI tax normalization. The Company adjusts its income tax expense to reflect any tax impact of its ENI adjustments. Adjusted EBITDA Adjusted EBITDA is defined as economic net income before interest, income taxes, depreciation and amortization. The Company notes that its calculation of Adjusted EBITDA may not be consistent with Adjusted EBITDA as calculated by other companies. The Company believes Adjusted EBITDA is a useful liquidity metric because it indicates the Company’s ability to make further investments in its business, service debt and meet working capital requirements. Refer to the reconciliation of U.S. GAAP net income attributable to controlling interests to ENI and Adjusted EBITDA. Segment ENI Segment ENI represents ENI for the Company’s reportable segment, calculated in accordance with the Company’s definition of Economic Net Income, before income tax, interest income and interest expense. Methodologies for calculating investment performance: Revenue-weighted investment performance measures the percentage of management fee revenue generated by Acadian strategies which are beating benchmarks. It calculates each strategy’s percentage weight by taking its estimated composite revenue over total composite revenues in each period, then sums the total percentage of revenue for strategies outperforming. Figures calculated using gross of fee strategy composite returns. Asset-weighted investment performance measures the percentage of AUM in strategies beating benchmarks. It calculates each strategy’s percentage weight by taking its composite AUM over total composite AUM in each period, then sums the total percentage of AUM for strategies outperforming. Figures calculated using gross of fee strategy composite returns. ENI operating earnings ENI operating earnings represents ENI earnings before Acadian LLC key employee distributions and is calculated as ENI revenue, less ENI operating expense, less ENI variable compensation. It differs from economic net income because it does not include the effects of Acadian LLC key employee distributions, net interest expense or income tax expense. Definitions and Additional Notes

24 Definitions and Additional Notes ENI operating margin The ENI operating margin, which is calculated before Acadian LLC key employee distributions, is used by management and is useful for investors to evaluate the overall operating margin of the business without regard to the Company’s ownership level of Acadian LLC. ENI operating margin is a non-GAAP efficiency measure, calculated based on ENI operating earnings divided by ENI revenue. The ENI operating margin is most comparable to the Company’s U.S.

GAAP operating margin. ENI management fee revenue ENI management fee revenue corresponds to U.S. GAAP management fee revenue.

ENI operating expense ratio The ENI operating expense ratio is used by management and is useful for investors to evaluate the level of operating expense as measured against the Company’s recurring management fee revenue. The Company has provided this ratio since many operating expenses, including fixed compensation & benefits and general and administrative expense, are generally linked to the overall size of the business. The Company tracks this ratio as a key measure of scale economies because in its profit sharing economic model, scale benefits both Acadian LLC employees and AAMI shareholders.

ENI earnings before variable compensation ENI earnings before variable compensation is calculated as ENI revenue, less ENI operating expense. ENI variable compensation ratio The ENI variable compensation ratio is calculated as variable compensation divided by ENI earnings before variable compensation. It is used by management and is useful for investors to evaluate consolidated variable compensation as measured against the Company’s ENI earnings before variable compensation.

Variable compensation is usually awarded based on a contractual percentage of Acadian LLC’s ENI earnings before variable compensation and may be paid in the form of cash, non-cash Acadian LLC equity or profit interests or AAMI equity. Hold Co variable compensation includes cash and AAMI equity. Non-cash variable compensation awards typically vest over several years and are recognized as compensation expense over that service period.

ENI Acadian LLC key employee distribution ratio The Acadian LLC key employee distribution ratio is calculated as Acadian LLC key employee distributions divided by ENI operating earnings. The ENI Acadian key employee distribution ratio is used by management and is useful to investors to evaluate Acadian LLC key employee distributions as measured against the Company’s ENI operating earnings. Acadian LLC key employee distributions represent the share of Acadian LLC profits after variable compensation that is attributable to Acadian LLC key employee equity and profit interests holders, according to their ownership interests.

For Acadian LLC profit interest distributions, the Hold Co is entitled to an initial preference over profits after variable compensation, structured such that before a preference threshold is reached, there would be no required key employee distributions, whereas for profits above the threshold the key employee distribution amount would be calculated based on the key employee economic percentages at Acadian LLC. U.S. GAAP operating margin U.S.

GAAP operating margin equals operating income from continuing operations divided by total revenue. Consolidated Funds Financial information presented in accordance with U.S. GAAP may include the results of consolidated pooled investment vehicles, or Funds, managed by Acadian LLC, where it has been determined that these entities are controlled by the Company.

Financial results which are “attributable to controlling interests” exclude the impact of Funds to the extent it is not attributable to the Company’s shareholders. Reinvested income and distributions Net flows include reinvested income and distributions. Reinvested income and distributions represent investment yield not distributed as cash, and reinvested back to the portfolios. n/m “Not meaningful.”
