Impairments of non-marketable securities - we have consistently excluded both one-time gains and one-time write-offs related to our investments in non-marketable securities from our pro forma results in order to keep quarter over quarter comparisons consistent. Reorganization costs - we exclude reorganization costs in order to present a consistent basis for quarterly comparisons and to more consistently present our results of operations. However, these measures should be considered in addition to, not as a substitute for, or superior to, operating income or other measures of financial performance prepared in accordance with generally accepted accounting principles as more fully discussed in Forrester's financial statements and filings with the Securities and Exchange Commission. 2

Forrester Research Announces Second-Quarter 2004 Financial Results

    CAMBRIDGE, Mass.--(BUSINESS WIRE)--July 27, 2004--Forrester
Research, Inc. (Nasdaq: FORR) today announced its second-quarter ended
June 30, 2004 financial results.

    Second-Quarter Financial Performance

    --  Total revenues were $34.9 million, compared with $34.0 million
        for the second quarter of last year.

    --  On a GAAP-reported basis, which reflects an effective tax rate
        of 33.5 percent, Forrester reported a second-quarter net loss
        of $2.3 million or $0.11 per diluted share, compared with net
        income of $141,000, or $0.01 per diluted share, for the same
        period last year.

    --  On a pro forma basis, which excludes amortization of $1.4
        million of acquisition-related intangible assets,
        reorganization costs of $6.8 million related primarily to
        office space consolidations, and non-marketable investment
        gains of $57,000 and which reflects a pro forma effective tax
        rate of 35 percent, net income was $3.0 million, or $0.13 per
        diluted share, for the second quarter of 2004. This compares
        with pro forma net income of $2.5 million, or $0.11 per
        diluted share, for the same period in 2003, which excludes
        amortization of $2.6 million of acquisition-related intangible
        assets, costs of $740,000 related to the integration of Giga
        Information Group, Inc., and a net write-down of $272,000
        related to impairments of certain non-marketable investments,
        and a pro forma effective tax rate of 35 percent.

    Six-Month Period Ended June 30, 2004, Financial Performance

    --  Total revenues were $66.7 million, compared with $58.5 million
        for the same period last year.

    --  On a GAAP-reported basis, which reflects an effective tax rate
        of 33.5 percent, Forrester reported a net loss of $2.6
        million, or $0.12 per diluted share for the six months ended
        2004, compared to net income of $1.9 million or $0.08 per
        diluted share for the same period last year.

    --  On a pro forma basis, which excludes amortization of $3.7
        million of acquisition-related intangible assets,
        reorganization costs of $8.8 million related primarily to
        office space consolidations, non-marketable investment gains
        of $57,000 and which reflects a pro forma effective tax rate
        of 35 percent, net income was $5.5 million, or $0.24 per
        diluted share, for the six months ended 2004. This compares
        with pro forma net income of $5.0 million, or $0.22 per
        diluted share for the same period last year, which excludes
        amortization of $3.5 million of acquisition-related intangible
        assets, costs of $771,000 related to the integration of Giga
        Information Group, Inc., and a net write-down of $572,000
        related to impairments of certain non-marketable investments,
        and a pro forma effective tax rate of 35 percent.

    A reconciliation of GAAP results to pro forma results may be found
in the attached financial tables.
    "Forrester's financial performance continued to improve in the
second quarter," said George F. Colony, chairman of the board and
chief executive officer. "Our client and dollar retention rates are
up, back to our target ranges. Product innovations and enhancements
are gaining traction, and technology spending is increasing at a
moderate pace. Overall, our second quarter results position us well
for the second half of 2004."

    Forrester Debuts Two New Products

    Also today, the company announced Forrester's Ultimate Consumer
Panel(TM) (Ultimate), an innovative, opt-in, highly secure consumer
data panel. Ultimate electronically captures online and offline
behavior from a representative group of more than 10,000 US
households. Clients including MasterCard, Wells Fargo & Company, and
Household Credit Card Services use Ultimate data and analysis to
better understand current and prospective customers, tailor marketing
strategies and messages, predict adoption for new products and
services, and gain intelligence on their market landscapes. See
separate press release at:
http://www.forrester.com/ER/Press/Release/0,1769,931,FF.html
    The Forrester Oval Program(TM) (executive membership offering)
today introduced three new membership groups for marketing
professionals. The CMO Group, Database Marketing Council, and Email
Marketing Council are designed for senior marketers at
business-to-consumer (B2C) companies. Clients such as Charming
Shoppes, Panasonic, and Thrifty Rental Car have joined Forrester's
Marketing Ovals to ensure their strategies are aligned with consumer
behavior. Through these specialized marketing membership programs,
Forrester helps marketing executives thrive in a world in which
technology increasingly influences consumer behavior.
    "Both of these new offerings - Ultimate and the Marketing Ovals --
are a natural progression for Forrester," said Colony. "For years, we
have researched technology's impact on consumer behavior and advised
marketing executives at our client companies. We are pleased that key
$1 billion-plus companies have already become clients of Ultimate and
the Marketing Ovals."
    Forrester is providing third-quarter and full-year 2004 guidance
as follows:

    Third-Quarter 2004 (GAAP):

        million.

        percent.

of approximately $8.8 million.

    --  Pro forma operating margin of approximately 11 percent to 13
        percent.

    --  Pro forma effective tax rate of 35 percent, which varies from
        our actual effective tax rate of 33.5 percent due to our
        tax-free interest income decreasing as a percentage of our pro
        forma pre-tax income.

    --  Pro forma diluted earnings per share of approximately $0.52 to
        $0.57.
