State Street Corporation Achieves Record Revenue and Operating EPS in
                            Second Quarter

                 Positive Operating Leverage Continues

    Strong Momentum at Investors Financial as Customer Conversions
                                 Begin


    BOSTON--(BUSINESS WIRE)--July 16, 2007--State Street Corporation
announced today second-quarter earnings per share of $1.07 compared to
$0.68 per share for the second quarter of 2006, which included
non-cash tax adjustments of $0.25 per share, or $0.93 per share
without those adjustments. Revenue of $1.921 billion in the second
quarter of 2007 represented a record and is up 16.4%, compared to
$1.651 billion in the year-ago quarter. Total expenses in the second
quarter of 2007 of $1.358 billion are up 15.5%, compared to $1.176
billion in the year-ago quarter. As a result, the Corporation
generated about 90 basis points of positive operating leverage. For
the second quarter of 2007, return on shareholders' equity is 19.2%,
compared to 14.0% in the second quarter of 2006 including the tax
adjustments or 19.2% excluding the tax adjustments. State Street's
acquisition of Investors Financial Services Corp. closed on July 2,
2007, and consequently, State Street's results for the quarter do not
reflect any contribution from the acquisition.

    Ronald E. Logue, State Street's chairman and chief executive
officer, said, "Our strong performance during the first six months of
this year demonstrates the successful execution of our global
strategy, while we continue to build for the future with our
acquisition of Investors Financial. The improved results are
particularly significant in view of last year's strong second quarter.
The 12 percent increase in servicing fees this quarter highlights our
ability to win new business globally while deepening relationships
with existing customers."

    Logue added, "State Street Global Advisors, which grew 22 percent
from last year's second quarter, continues to make a larger
contribution to our bottom line as it places greater emphasis on its
quantitative active strategies. We are pleased to achieve the eleventh
consecutive quarter of positive operating leverage compared to the
prior-year quarter. We also continued to benefit from our balance
sheet strategy. We achieved 1.64 percent in net interest margin on a
44 percent improvement in fully taxable-equivalent net interest
revenue."

    Logue concluded, "The results of Investors Financial in the second
quarter were strong, like State Street's, and so we are revising our
financial goals for 2007: We now expect that revenue growth will be
between 20 percent and 22 percent; up from 16 percent to 18 percent we
forecast in February when we announced the deal. Excluding merger and
integration charges, growth in operating earnings per share will be
between 10 percent and 15 percent; and operating return on equity will
be between 14 percent and 17 percent, both of which were our original
financial goals we established more than two years ago. We expect to
achieve in the upper half of each of these ranges for 2007."

    SECOND QUARTER RESULTS VS. YEAR-AGO QUARTER

    Total revenue increased 16.4% to $1.9 billion in the second
quarter of 2007 compared to the second quarter of 2006, and total
expenses grew 15.5% to $1.4 billion over the same period.

    Servicing fees are up 12%, to $766 million from $683 million in
last year's second quarter. The increase is attributable to new
business from existing and new customers in 2007 and higher equity
market valuations. Total assets under custody are $13.04 trillion at
June 30, 2007, up 20%, compared with $10.86 trillion a year ago. Daily
average values for the S&P 500 Index are up 17%, for the MSCI(R) EAFE
Index(SM) are up 22%, and for the NASDAQ are up 14%, during the second
quarter 2007 from the year-ago quarter.

    Investment management fees, generated by State Street Global
Advisors, are $284 million, up 22% from $232 million a year ago.
Management fees reflect continued new business and an increase in
average month-end equity valuations. Total assets under management are
$1.93 trillion at June 30, 2007, up 26%, compared to $1.53 trillion
the previous year.

    Trading services revenue, which includes foreign exchange trading
revenue and brokerage and other fees, is $260 million for the quarter,
up 1% from $258 million a year ago. The slight improvement was due
primarily to new revenue streams generated from our Currenex
acquisition, offset somewhat by weaker volatility in foreign exchange.

    Securities finance revenue is $162 million in the quarter, up 27%
compared to $128 million in the year-ago quarter, primarily reflecting
an increase in demand. Both quarters' results represent seasonally
high activity.

    Processing fees and other revenue are down 12% at $65 million,
compared to $74 million primarily due to the consolidation of
tax-exempt investments onto the balance sheet in the third quarter of
2006.

    Net interest revenue on a fully taxable-equivalent basis is $397
million, an increase of $122 million, or 44%, from $275 million a year
ago. The increase in net interest revenue is due to a favorable mix of
deposits and improved spreads. Net interest margin increased to 1.64%
from 1.20% a year ago.

    Expenses increased from $1.176 billion to $1.358 billion, up $182
million, or 15.5%. Salaries and benefits expenses are up 18% to $808
million, primarily attributable to incentive compensation due to
improved performance, increased staffing to support new business, and
merit increases. Expenses for information systems & communications
decreased $1 million, to $128 million. The increase in expenses
includes higher transaction processing services, up 5% to $141
million, due to higher volumes. Occupancy expense increased 3%, or $3
million, to $98 million. Other expenses increased 37% to $183 million
from $134 million due to costs associated with the acquisitions and
with new business initiatives, as well as sales promotion expenses.

    SECOND-QUARTER 2007 RESULTS VS. FIRST QUARTER 2007

    Second-quarter earnings per share of $1.07 is up 15%, compared to
earnings per share of $0.93 in the first quarter. Total revenue in the
second quarter of $1.921 billion is up 13.3% versus $1.696 billion in
the first quarter. Total expenses are $1.358 billion, up 12.0% versus
$1.213 billion in the first quarter. As a result, the Corporation
generated about 130 basis points of positive operating leverage. For
the second quarter of 2007, return on shareholders' equity is 19.2%
compared with 17.4% in the first quarter.

    Servicing fees are up 7% to $766 million and management fees are
up 9% to $284 million, both due to new business and higher equity
valuations. Trading services increased 18% to $260 million due to
strength in foreign exchange volumes and brokerage. Securities finance
revenue increased 65%, from $98 million to $162 million, due to
improved spreads and seasonally high volumes. Processing fees and
other revenue are down from $73 million to $65 million primarily due
to lower fees from leasing and structured products. Net interest
revenue on a fully taxable-equivalent basis increased $60 million, or
18%, to $397 million, compared to $337 million in the first quarter.

    Salaries and employee benefits total $808 million, an increase of
$69 million, or 9%, from $739 million, attributable to the impact of
incentive compensation due to improved performance, increased staffing
to support new business, and benefit increases. Transaction processing
services increased $12 million, or 9%, to $141 million due to an
increase in volumes. Information systems and communications expense is
up 2%, or $3 million, to $128 million. Occupancy increased $4 million
or 4% to $98 million. Other expenses are up $57 million, or 45%, from
$126 million to $183 million primarily as a result of costs associated
with new business initiatives and with the acquisitions, as well as
increased securities processing expenses.

    The effective tax rate for the second quarter is 35.0%, flat with
the first quarter.
