                           AMG REPORTS FINANCIAL AND
                  OPERATING RESULTS FOR FIRST QUARTER 2001

                      COMPANY REPORTS CASH EPS OF $0.89
     NET CLIENT CASH FLOWS FROM DIRECTLY MANAGED ASSETS WERE $880 MILLION

BOSTON, MA, APRIL 25, 2001 - Affiliated Managers Group, Inc. (NYSE: AMG)
today reported its financial and operating results for the quarter ended
March 31, 2001.

Cash earnings per share ("Cash EPS") for the first quarter of 2001 were $0.89
versus Cash EPS of $0.92 for the first quarter of 2000. This decrease from
the prior year reflects the impact of the broad equity market decline which
offset earnings gains from net client cash flows. (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 first quarter of 2001 were $0.53, compared to $0.60 for the
first quarter of 2000. Cash Net Income (net income plus the non-cash charges
for depreciation and amortization of intangible assets) was $20.2 million,
compared to $21.2 for the first quarter of 2000, while EBITDA was $31.3
million, compared to $34.7 million for the same period of 2000. Revenues for
the first quarter of 2001 were $100.5 million, compared to $114.8 million for
the first quarter of 2000. Net income for the first quarter of 2001 was $11.9
million, compared to $13.8 million for the same period of 2000.

The aggregate assets under management of AMG's affiliated investment
management firms at March 31, 2001 were $69.7 billion. Aggregate net client
cash flows of directly managed assets were $880 million, while outflows of
overlay assets were $1.35 billion during the quarter. These aggregate net
client cash flows (including directly managed and overlay assets) for the
quarter resulted in a net increase of approximately $3.9 million to AMG's
annualized EBITDA.

"While the sharp declines in the equity market during the first quarter
obviously presented challenges for our Affiliates, we were pleased with their
results relative to their competitors and benchmarks," said William J. Nutt,
Chairman and Chief Executive Officer. "The strength of our Affiliates'
businesses is seen in their solid net client inflows during the quarter,
especially as measured in terms of increased contribution to earnings. Once
again, AMG benefited from the diversification among our Affiliate group," Mr.
Nutt continued. "The results of our value managers such as Tweedy, Browne;
Rorer; Skyline and Systematic helped offset market-related declines in
managed assets among Affiliates focused on growth sectors of the market."

"Notwithstanding the market environment, we continue to invest in growth
initiatives," said Sean Healey, President and Chief Operating Officer. "Our
investment in Dublin Fund Distributors, a firm which distributes alternative
investment products in the European institutional and high net worth markets,
offers great potential for stand-alone growth as well as enhanced
distribution of Affiliates' products. In addition, on April 10, we announced
the merger of our Renaissance Affiliate with another Cincinnati-based
manager, Bowling Portfolio Management, which should enhance AMG's earnings
growth while benefiting the firms' management partners. Finally, we remain
committed to and confident in our strategy of investing in growing mid-sized
asset management firms."

AMG is an asset management company that acquires and holds majority interests
in a diverse group of mid-sized investment management firms. The Company's
strategy is to generate growth through the internal growth of its existing
Affiliates, as well as investments in new Affiliates. AMG's innovative
transaction structure allows individual members of each Affiliate's
management 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.
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 interest 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, 2000.
