ITEM 7. Financial Statements and Exhibits. (c) Exhibits 99.1 Press Release dated April 30, 2003. ITEM 9. (Information Provided Under Item 12, DISCLOSURE OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION). The information contained in this Item 9 is furnished pursuant to Item 12 of Form 8-K "Results of Operations and Financial Condition," in accordance with SEC Release No. 33-8216. This information and the exhibits hereto are being furnished and shall not be deemed to be "filed" for the purposes of Section 18 of, or otherwise regarded as filed under, the Securities Exchange Act of 1934, as amended. The information contained in this report shall not be incorporated by reference into any filing of Forrester Research, Inc. with the SEC, whether made before or after the date hereof, regardless of any general incorporation language in such filings. On April 30, 2003, Forrester Research, Inc. issued a press release announcing its financial results for the quarter ended March 31, 2003, the full text of which is attached hereto as Exhibit 99.1. Forrester believes that pro forma financial results provide investors with consistent and comparable information to aid in the understanding of Forrester's ongoing business. Our pro forma presentation excludes the following: Amortization of acquisition-related intangibles - we exclude the non-cash effect of the amortization of acquisition-related intangibles from our pro forma results in order to more consistently present our ongoing results of operations. 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. Restructuring charges - we excluded restructuring charges from our first quarter 2002 pro forma results because our failure to do so would present a misleading improvement in our pro forma results in the first quarter of 2003 as compared to the same period in 2002. 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 the Forrester's financial statements and filings with the Securities and Exchange Commission. -2-

Exhibit 99.1 FOR IMMEDIATE RELEASE FORRESTER RESEARCH ANNOUNCES FIRST-QUARTER 2003 FINANCIAL RESULTS CAMBRIDGE, Mass., April 30, 2003... Forrester Research, Inc. (Nasdaq: FORR) today announced financial results for the first quarter ended March 31, 2003, in line with its previous financial guidance. FIRST-QUARTER FINANCIAL PERFORMANCE - - Total revenues were $24.8 million, compared with $26.1 million for the first quarter of last year. - - On a GAAP-reported basis, which reflects an effective tax rate of 31 percent, Forrester reported first-quarter net income of $1.8 million, or $0.08 per diluted share compared to a net loss of $6.1 million, or $0.26 per diluted share for the same period last year. - - On a pro forma basis, which excludes amortization of acquisition-related intangible assets of $924,000 and a write-down of $300,000 related to impairments of certain non-marketable securities, and which reflects a pro forma effective tax rate of 35 percent, pro forma net income was $2.5 million, or $0.11 per diluted share, for the first quarter of 2003. The pro forma effective tax rate of 35 percent varies from our actual effective tax rate of 31 percent due to our tax-free interest income decreasing as a percentage of our pro forma pre-tax income. This compares with pro forma net income of $3.3 million, or $0.14 per diluted share for the same period last year, which excludes the reorganization costs of $9.1 million, amortization of acquisition-related intangible assets of $82,000, and impairment charges of $2.2 million. A reconciliation of GAAP results to pro forma results may be found in the attached financial tables. GIGA INTEGRATION "Although Forrester's first quarter was extremely busy with the acquisition and integration of Giga Information Group, we remained focused on our clients and were pleased to meet our financial guidance," said George F. Colony, chairman of the board and chief executive officer. "Client satisfaction remains the top priority throughout this integration and clients will continue to be served by the same research and account teams in 2003. We are selling two distinct but complementary research brands -- Forrester and Giga. Behind the scenes, integration is ahead of schedule, and we are already achieving economies of scale in our general and administrative functions." Additionally, Forrester integrated Giga's ForSITE(TM) offering into the Forrester Oval Program(TM)'s CIO Group during the first quarter. The combined board, which consists of 80 members, provides CIOs with a peer network, client-directed research, benchmark data, best practices, and short projects. Along with the CIO Group, three other technology councils from Giga now constitute the Forrester Oval Program: Applications and Development, Security, and Enterprise Architecture. "We strongly believe the new Forrester value proposition is differentiated in the marketplace," said Colony. "Forrester helps companies plan while Giga helps them act. Aligning these two powerful offerings will create amazing value for our clients." CUSTOM CONSUMER RESEARCH - More -
