Exhibit 99.1 Plumtree Software Exceeds Guidance for Third Quarter 2004; Annual User Conference Scheduled October 11 Through 14, 2004 SAN FRANCISCO--(BUSINESS WIRE)--Oct. 6, 2004--Plumtree Software (Nasdaq:PLUM) today announced that it expects to exceed the third quarter revenue guidance it provided on July 15, 2004, as well as narrow the projected loss per share as compared to previously provided guidance for the third quarter of 2004. Plumtree now expects revenues for the third quarter ended September 30, 2004, to be between $21.5 million and $22.5 million with net loss per share expected to be between ($0.09) and ($0.12) per share, calculated in accordance with generally accepted accounting principals (GAAP). Non-GAAP net loss per share for the quarter ended September 30, 2004 is expected to be between ($0.06) and ($0.09). On July 15, 2004, the Company provided guidance of revenues between $19 million and $20 million with a GAAP and non-GAAP loss between ($0.14) and ($0.17) and ($0.11) and ($0.14) per share, respectively. The Company attributed the strong results to a number of factors, including early adoption of the newly released Java version of its product; a very strong quarter of public sector sales; and the positive contributions from new management personnel added over the past few quarters. During the third quarter the Company recorded three deals of greater than $1 million on both its .NET and newly released Java portal products. Use of GAAP and Non-GAAP Results Non-GAAP net loss excludes charges for amortization of deferred stock-based compensation, amortization of acquired technology, and assumes an effective tax rate of 30% on net loss, if any. A reconciliation of these non-GAAP results to GAAP results is included in the table below. Range - ---------------------------------------------------------------- Expected GAAP net loss per share (.09) (.12) - ------------------------------------------------- ------- ------ Add back: Amortization of stock-based compensation and acquired technology .02 .02 - ------------------------------------------------- ------- ------ Add back: Taxes .01 .01 - ------------------------------------------------- ------- ------ Expected non-GAAP net loss per share (.06) (.09) - ------------------------------------------------- ------- ------ Plumtree's management believes that a presentation of operating costs and expenses excluding amortization of deferred stock-based compensation, amortization of acquired technology, and assuming a fixed effective tax rate, provides a meaningful basis for evaluating our underlying cost and expense levels. Presentation of non-GAAP net income and earnings per share information provides greater comparability of Plumtree's financial results against historical results as well as those of other enterprise software companies and financial models of securities analysts.
