(NYSE: BSIG) reports its results for the fourth quarter ended December 31, 2021. Suren Rana, BrightSphere’s President and Chief Executive Officer said, “Having completed the divestitures of all our affiliates other than Acadian over the last few quarters, fourth quarter of 2021 was the first quarter with the Company operating as a pure-play and differentiated quant-focused business rather than a multi-boutique asset manager. We are now a market leading business focused on providing quantitative strategies and solutions to institutional clients around the globe and we are pleased that in Q4 ’21, we continued to outperform for our clients and produced strong financial results. As of December 31, 2021, 89%, 82%, 86% and 90% of our strategies by revenue beat their respective benchmarks over the prior 1-, 3-, 5-, and 10- year periods. Turning to our financial results, the Company produced ENI earnings per share of $0.53 for the fourth quarter of 2021 compared to $0.28 in the fourth quarter of 2020 and $0.28 in the third quarter of 2021. Acadian, our sole operating business, generated $87.6 million of Adjusted EBITDA in the fourth quarter of 2021 compared to $40.4 million in the fourth quarter of 2020 and $49.1 million in the third quarter of 2021. The increase in EBITDA and EPS compared to prior quarters was primarily driven by strong performance fees. Acadian’s net client cash flows in the fourth quarter of 2021 were $(0.8) billion with an annualized revenue impact of $0.1 million compared to net client cash flows of $(1.3) billion with an annualized revenue impact of $(6.1) million for Q4'20. We returned $1.1 billion of capital to our shareholders by buying back 45% of our outstanding shares through the tender offer in December 2021. Subsequent to the quarter-end, we also redeemed $125 million of retail notes. Pro forma for this redemption, our cash balance is $125 million. We expect to continue deploying excess capital toward share repurchases and to support organic growth.”

31 Definitions and Additional Notes References to “BrightSphere,” “BSIG” or the “Company” refer to BrightSphere Investment Group Inc.; references to “OM plc” or “Parent” refer to Old Mutual plc, the Company’s former parent; references to “BSUS” or the “Center” refer to the holding company excluding the Affiliates. BrightSphere operates its business through one asset management firm (the “Affiliate”). BrightSphere’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 Affiliate 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 Affiliates by consolidated Funds, which are viewed as investment income under U.S. GAAP. • include the Company’s share of earnings from equity-accounted Affiliates within other income, rather than investment income; • treat sales-based compensation as a general and administrative expense, rather than part of fixed compensation and benefits; • identify separately from operating expenses, variable compensation and Affiliate key employee distributions, which represent Affiliate earnings shared with Affiliate key employees; and • net the separate revenues and expenses recorded under U.S. GAAP for certain Fund expenses initially paid by the Company’s Affiliates on the Fund’s behalf and subsequently reimbursed, to better reflect the actual economics of the Company’s business. 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 Affiliate equity and profit interests held by Affiliate key employees. These ownership interests may in certain circumstances be repurchased by BrightSphere 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 BrightSphere 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. It also excludes the amortization of acquisition-related contingent consideration, as well as the value of employee equity owned pre-acquisition, where such items have been included in compensation expense as a result of ongoing service requirements for certain employees. Please note that the revaluations related to these acquisition-related items are included in (i) above. 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 Affiliate 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 and the impact of a one-time compensation arrangement entered into that includes advances against future compensation payments. 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.

32 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 each of the Company’s reportable segments, 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 Affiliate 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. Equal-weighted investment performance measures the percentage of Affiliate scale strategies (defined as strategies with greater than $100 million of AUM) beating benchmarks. Each outperforming strategy over $100 million has the same weight; the calculation sums the number of strategies outperforming relative to the total number of composites over $100 million. 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. ENI operating earnings ENI operating earnings represents ENI earnings before Affiliate 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 Affiliate key employee distributions, net interest expense or income tax expense. ENI operating margin The ENI operating margin, which is calculated before Affiliate key employee distributions, is used by management and is useful to investors to evaluate the overall operating margin of the business without regard to the Company’s various ownership levels at each of the Affiliates. 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 to 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 at BrightSphere because in its profit sharing economic model, scale benefits both the Affiliate employees and BrightSphere shareholders. Definitions and Additional Notes

33 Definitions and Additional Notes 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 to 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 each Affiliate’s ENI earnings before variable compensation and may be paid in the form of cash or non-cash Affiliate equity or profit interests. Center variable compensation includes cash and BrightSphere equity. Non-cash variable compensation awards typically vest over several years and are recognized as compensation expense over that service period. ENI Affiliate key employee distribution ratio The Affiliate key employee distribution ratio is calculated as Affiliate key employee distributions divided by ENI operating earnings. The ENI Affiliate key employee distribution ratio is used by management and is useful to investors to evaluate Affiliate key employee distributions as measured against the Company’s ENI operating earnings. Affiliate key employee distributions represent the share of Affiliate profits after variable compensation that is attributable to Affiliate key employee equity and profit interests holders, according to their ownership interests. At certain Affiliates, BSUS 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 its consolidated Affiliates. 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 the Company’s Affiliates, 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. Annualized revenue impact of net flows (“NCCF”) Annualized revenue impact of net flows represents annualized management fees expected to be earned on new accounts and net assets contributed to existing accounts (inflows), less the annualized management fees lost on terminated accounts or net assets withdrawn from existing accounts (outflows), plus revenue impact from reinvested income and distribution. Annualized management fee for client flow is calculated by multiplying the annual gross fee rate for the relevant account with the inflow or the outflow, including equity-accounted Affiliates. In addition, reinvested income and distribution for each segment is multiplied by average fee rate for the respective segment to compute the revenue impact. Reinvested income and distributions Net flows include reinvested income and distributions made by BrightSphere’s Affiliates. Reinvested income and distributions represent investment yield not distributed as cash, and reinvested back to the portfolios. Realizations and Other Realizations include distributions related to the sale of alternative assets and represent return on investments. n/m “Not meaningful.”
