AMG Reports Financial and Operating Results for
Second Quarter and First Half of 2003

Company Reports EPS of $0.64; Cash EPS of $1.16

Boston, MA, July 23, 2003—Affiliated Managers Group, Inc. (NYSE: AMG) today reported its financial and operating results for the quarter and six months ended June 30, 2003.

Cash earnings per share ("Cash EPS") for the second quarter of 2003 were $1.16, compared to $1.12 for the second quarter of 2002, while diluted earnings per share for the second quarter of 2003 were $0.64, compared to $0.67 for the same period of 2002. Cash Net Income was $24.9 million for the second quarter of 2003, compared to $25.7 million for the second quarter of 2002. Net Income for the second quarter of 2003 was $13.8 million, compared to $15.4 million for the second quarter of 2002. (Cash EPS and Cash Net Income are defined in the attached tables.)

For the second quarter of 2003, revenue was $116.7 million, compared to $129.6 million for the second quarter of 2002. EBITDA for the second quarter of 2003 was $34.7 million, compared to $37.4 million for the same period of 2002.

For the six months ended June 30, 2003, Cash Net Income was $49.0 million, while EBITDA was $67.3 million. For the same period, Net Income was $26.8 million, on revenue of $226.9 million. For the six months ended June 30, 2002, Cash Net Income was $50.4 million, while EBITDA was $72.8 million. For the same period, Net Income was $29.9 million, on revenue of $249.0 million.

Net client cash flows from directly managed assets were outflows of $184 million, while inflows of overlay assets were approximately $5 million. Net inflows in the institutional and mutual fund channels were $54 million and $192 million, respectively, while net outflows in the high net worth channel were $425 million. These aggregate net client cash flows for the quarter resulted in an increase of approximately $0.2 million to AMG's annualized EBITDA (as the financial impact of inflows to higher margin products exceeded the impact of outflows from lower margin products). The aggregate assets under management of AMG's affiliated investment management firms at June 30, 2003 were $77.3 billion.

"We are pleased with our results for the quarter, as improving equity market conditions, along with a positive contribution from net client cash flows, helped produce solid earnings growth," stated William J. Nutt, Chairman and Chief Executive Officer. "While the diversity among our Affiliates' investment styles and distribution channels provided relative stability to our earnings during periods of declining equity markets, looking ahead, with approximately 95% of our EBITDA generated by equity products, AMG is well positioned to benefit from improving equity markets."

"Our recent distribution and efficiency-oriented initiatives in the Affiliate Development area continue to gain momentum," stated Sean M. Healey, President and Chief Operating Officer. "Portfolio Services Group, the separate account distribution platform we launched at the beginning of the year, added an additional, major sponsor to the list of brokerage firms offering our multi-Affiliate separate account portfolios. PSG also added two more Affiliates, Systematic and Renaissance, to the roster of Affiliates whose products are now available to the retail market through PSG. In addition, Advantage Outsourcing Solutions, the centralized back office platform we launched at the beginning of the second quarter, continued to expand its client base."

Mr. Healey added, "Prospects for investments in new Affiliates have improved substantially with the more favorable climate in the equity markets, as the principals of mid-sized firms are able to refocus on succession planning and transition issues. While it is always difficult to predict the timing of new investments, we are confident that over time we will continue to add meaningful earnings growth to AMG through new investments."

AMG is an asset management company with equity investments in a diverse group of mid-sized investment management firms. AMG's strategy is to generate growth through the internal growth of its existing Affiliates, as well as through investments in new Affiliates. AMG's innovative transaction structure allows individual members of each Affiliate's management team to retain or receive significant direct equity ownership in their firm while maintaining operating autonomy. In addition, AMG provides centralized assistance to its Affiliates in strategic matters, marketing, distribution, product development and operations.


Certain matters discussed in this press release may constitute forward-looking statements within the meaning of the federal securities laws. Actual results and the timing of certain events could differ materially from those projected in or contemplated by the forward-looking statements due to a number of factors, including changes in the securities or financial markets or in general economic conditions, the availability of equity and debt financing, competition for acquisitions of interests in investment management firms, the investment performance of our Affiliates and their ability to effectively market their investment strategies, and other risks detailed from time to time in AMG's filings with the Securities and Exchange Commission. Reference is hereby made to the "Cautionary Statements" set forth in the Company's Form 10-K for the year ended December 31, 2002.

Affiliated Managers Group, Inc.
Notes

(A)
Cash Net Income is defined as Net Income plus amortization and deferred taxes related to intangible assets plus Affiliate depreciation. This supplemental non-GAAP performance measure is provided in addition to, but not as a substitute for, Net Income. The Company considers Cash Net Income an important measure of its financial performance, as management believes it best represents operating performance before non-cash expenses relating to the acquisition of interests in its affiliated investment management firms. Since acquired assets do not generally depreciate or require replacement, and since they generate deferred tax expenses that are unlikely to reverse, the Company adds back these non-cash expenses. Cash Net Income is used by the Company's management and Board of Directors as a principal performance benchmark.

    The Company adds back amortization attributable to acquired client relationships because this expense does not correspond to the changes in value of these assets, which do not diminish predictably over time. The Company adds back the portion of deferred taxes generally attributable to intangible assets (including goodwill) that it no longer amortizes but which continue to generate tax deductions. These deferred tax expense accruals would be used in the event of a future sale of an Affiliate or an impairment charge, which the Company considers unlikely. The Company adds back the portion of consolidated depreciation expense incurred by Affiliates because under its Affiliate operating agreements, the Company is generally not required to replenish these depreciating assets.

    In connection with its February 2003 issuance of convertible securities, the Company modified its definition to clarify that deferred taxes relating to these convertible securities and certain depreciation are not added back for the calculation of Cash Net Income. In prior periods, Cash Net Income was defined as "Net Income plus depreciation, amortization and deferred taxes." If the Company had used its modified definition of Cash Net Income in 2002, Cash Net Income would have been $25,250 for the three months ended June 30, 2002 and $49,540 for the six months ended June 30, 2002.

(B)
EBITDA is defined as earnings before interest expense, income taxes, depreciation and amortization. This supplemental non-GAAP liquidity measure is provided in addition to, but not as a substitute for, cash flow from operations. As a measure of liquidity, the Company believes EBITDA is useful as an indicator of its ability to service debt, make new investments and meet working capital requirements. EBITDA, as calculated by the Company, may not be consistent with computations of other companies. In reporting EBITDA by segment, Affiliate expenses are allocated to a particular segment on a pro rata basis with respect to the revenue generated by that Affiliate in such segment.

(C)
Cash earnings per share represents Cash Net Income divided by average shares outstanding. The Company's current presentation of Cash EPS represents a change of the measure presented in prior periods, as discussed in footnote A. If the Company had used its modified definition of Cash EPS in 2002, Cash EPS would have been $1.10 for the three months ended June 30, 2002 and $2.16 for the six months ended June 30, 2002.

(D)
For the three and six months ended June 30, 2002, this figure represents the Company's total deferred taxes.

(E)
For the three and six months ended June 30, 2002, this figure represents the Company's consolidated depreciation.
