Financial Statements and Exhibits. (c) Exhibits 99.1 Press Release dated October 22, 2003. ITEM 12. RESULTS OF OPERATIONS AND FINANCIAL CONDITION. The information contained in this current report on Form 8-K is furnished pursuant to Item 12 of Form 8-K "Results of Operations and Financial Condition". 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 October 22, 2003, Forrester Research, Inc. issued a press release announcing its financial results for the quarter ended September 30, 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. Integration costs - we exclude the costs related to our acquisition of Giga, which are primarily related to orientation events and data migration, in order to present a consistent basis for quarterly comparisons. 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 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 nine months ended September 30, 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. SIGNATURE Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
