                   AMG REPORTS FINANCIAL AND OPERATING RESULTS
                      FOR FOURTH QUARTER AND FULL YEAR 1998

    COMPANY REPORTS FOURTH QUARTER EBITDA OF $24.0 MILLION AND EPS OF $0.48

BOSTON, MA, JANUARY 27, 1999 -- Affiliated Managers Group, Inc. (NYSE:AMG), an
asset management holding company, today reported its financial and operating
results for the fourth quarter and full year ended December 31, 1998.

Reported net income for the fourth quarter was $9.3 million, or $0.48 per share
on a diluted basis, on revenues of $80.3 million. Reported earnings before
interest expense, income taxes, depreciation and amortization ("EBITDA") for the
fourth quarter was $24.0 million. These results compare to reported net income
before extraordinary item for the fourth quarter 1997 of $0.8 million, or $0.07
per share on a diluted basis, on revenues of $42.0 million, and EBITDA before
extraordinary item of $12.1 million. The revenues, EBITDA and net income for the
fourth quarter 1998 include substantial performance fees which, due to their
dependence on investment results, may not recur to the same magnitude in future
years.

For the year ended December 31, 1998, reported net income was $25.6 million, or
$1.33 per share on a diluted basis, on revenues of $238.5 million, while on a
reported basis, EBITDA for the year ended December 31, 1998 was $76.3 million.
For the year ended December 31, 1997, reported net income before the
extraordinary item was $1.6 million, or $0.20 per share on a diluted basis, on
revenues of $95.3 million. Reported EBITDA for the year ended December 31, 1997
was $20.0 million.

On a pro forma basis (giving effect to the investments in Essex Investment
Management Company, LLC, completed on March 20, 1998, Davis Hamilton Jackson &
Associates, L.P., completed on December 31, 1998, and Rorer Asset Management,
LLC, completed on January 6, 1999, as if each occurred as of January 1, 1998),
net income for the year ended December 31, 1998 was $28.3 million, or $1.45 per
share. EBITDA on the same pro forma basis for the year ended December 31, 1998
was $89.3 million.

Affiliated Managers Group Reports 4Q98 and Full Year 1998 Results
January 27, 1999
Page 2 of 5


Pro forma for the investment in Rorer, assets under management at December 
31, 1998 were $62.1 billion. Assets under management by Tweedy, Browne 
Company LLC, AMG's largest Affiliate based on EBITDA Contribution (as defined 
in Note 6 to the attached Summary Financial Data), rose to $6.6 billion, a 
24.3 percent increase for the year. Aggregate net client cash flows were 
positive for the year at $160 million, although those for the fourth quarter 
were negative $1.5 billion due to a decline in assets indirectly managed 
using "overlay" strategies. Overlay assets (which generally carry lower fees 
than directly managed assets) declined by $1.6 billion in the fourth quarter 
and for the year. Excluding the effect of these overlay assets, aggregate 
directly managed assets of AMG's Affiliates increased by $170 million in the 
fourth quarter and $1.7 billion for the year.

"We are pleased with AMG's strategic and financial achievements in 1998, our
first year as a public company," said William J. Nutt, Chairman, President, and
Chief Executive Officer. "Notwithstanding volatile markets in the latter half of
the year, our Affiliates produced impressive growth resulting from strong
investment performance and positive aggregate net client cash flows over the
year. In addition, we continued to successfully execute our strategy of
generating growth through investments in new Affiliates. With the additions of
Rorer, Davis Hamilton, and Essex, AMG has grown to 13 Affiliates. These new
Affiliates further expand AMG's diversity by asset class, investment style,
client type, and geographic region. Finally, we are also pleased to have
assisted one of our Affiliates, The Burridge Group LLC, in acquiring an
excellent firm, Sound Capital Partners, LLC, in July of 1998."

AMG was founded in 1993 to address the succession and transition issues facing
the founders and owners of many mid-sized investment firms. AMG's strategy is to
generate growth through new investments, as well as through the internal growth
of existing 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, when requested, in strategic
matters, marketing, product development, and operations support.
