Plumtree Hires New Chief Operating Officer, Vice President of Worldwide Sales
SAN FRANCISCO, Calif., April. 15, 2004 — Enterprise Web leader Plumtree Software (Nasdaq: PLUM) today announced results for its first quarter ended March 31, 2004. Revenue for the first quarter of 2004 was $17.7 million, compared to $18.8 million in revenue for the fourth quarter of 2003 and $17.2 million in revenue for the comparable quarter last year. Net loss for the first quarter of 2004 calculated in accordance with generally accepted accounting principles (GAAP) was $3.4 million, or $0.11 per share, compared to a net loss of $552,000, or $0.02 per share, for the fourth quarter of 2003, and net income of $529,000, or $0.02 per share, for the comparable quarter last year. Pro forma net loss for the first quarter of 2004 was approximately $2.6 million, or $0.08 per share, compared to pro forma net income of $270,000, or $0.01 per share, for the fourth quarter of 2003 and pro forma net income of $1.1 million, or $0.04 per share, for the comparable quarter last year.
Pro forma net income excludes charges for amortization of deferred stock-based compensation, amortization of acquired technology, and assumes an effective tax rate of 30% on net income, if any. A reconciliation of these pro forma results to GAAP is included in the financial tables below.
As of March 31, 2004, Plumtree’s cash, cash equivalents and short-term investments had increased for the fourteenth consecutive quarter, totaling approximately $68.5 million, up from $67.7 million in the previous quarter. Plumtree has no long-term debt.
“This quarter, we invested in four key long-term growth initiatives: channels, partner applications, industry solutions and a product strategy of Radical Openness,” said Plumtree President and CEO John Kunze. “We seeded future market opportunities with the launch of our partner applications program, reorganized our field organization around retail and life sciences industry solutions, and, most importantly, hired senior executives from Oracle and BearingPoint to execute on a multi-channel applications strategy. These efforts will take time, but our strong balance sheet and our fundamental assets of customer success and open technology position us to be the openness leader in an emerging market for service-oriented applications.”
