Cash earnings per share ("Cash EPS") for the second quarter of 2001 were $0.95 compared to Cash EPS of $0.95 for the second quarter of 2000 and $0.89 for the first quarter of 2001. (Cash EPS is the Company's reported EPS figure plus the non-cash charges on a per share basis for depreciation and amortization of intangible assets which arise from the use of the purchase method of accounting. The Company considers Cash EPS to be the most meaningful measure of its financial performance.) Diluted earnings per share for the second quarter of 2001 were $0.58, compared to $0.61 for the second quarter of 2000. Cash Net Income (net income plus the non-cash charges for depreciation and amortization of intangible assets) was $21.5 million, compared to $21.3 million for the second quarter of 2000, while EBITDA was $33.6 million, compared to $34.9 million for the same period of 2000. Revenues for the second quarter of 2001 were $100.7 million, compared to $110.9 million for the second quarter of 2000. Net income for the second quarter of 2001 was $13.1 million, compared to $13.7 million for the same period of 2000. For the six months ended June 30, 2001, Cash Net Income was $41.7 million, or $1.84 on a per share basis, while EBITDA was $64.9 million. For the same period, net income was $25.0 million, or $1.11 on a per share basis, on revenues of $201.1 million. For the six months ended June 30, 2000, Cash Net Income was $42.5 million, or $1.86 on a per share basis, while EBITDA was $69.6 million. For the same period, net income was $27.5 million, or $1.21 on a per share basis, on revenues of $225.7 million. The aggregate assets under management of AMG's affiliated investment management firms at June 30, 2001 were $73.7 billion. Aggregate net client cash flows of directly managed assets were $1.1 billion, while outflows of overlay assets were $40.0 million during the quarter.

Affiliated Managers Group, Inc. Reports Financial and Operating Results For Second Quarter and First Half of 2001 July 25, 2001 Page 2 of 7 "Our Affiliates had a strong second quarter during a period of modest improvement in the equity market environment," said William J. Nutt, Chairman and Chief Executive Officer. "Our Cash EPS grew nearly 7% quarter over quarter, as our Affiliates posted solid investment results and continued to achieve steady growth in client cash flows, with over $1 billion from directly managed net flows in the quarter." Sean M. Healey, President and Chief Operating Officer, stated, "We were pleased to announce the completion in June of the merger between our Affiliate, Renaissance Investment Management, and Bowling Portfolio Management. AMG sourced, structured and financed the merger, and the combination of these Cincinnati-based managers will enable them to recognize a number of synergies, enhance their administrative and marketing capabilities, and offer complementary investment styles." Mr. Healey continued, "Another important achievement in the quarter was the successful execution of our $221 million zero-coupon convertible senior notes offering in May. This security lowers our cost of capital and increases our capacity to fund new investments. Finally, we continued to make good progress during the quarter toward investing in additional growing, high quality mid-sized investment management firms." AMG is an asset management company that addresses the succession and transition issues facing the principals of growing 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 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.
