“95% revenue growth in 2007, and passing $100 million in annual bookings in our first six years, is an extraordinary achievement,” said Lars Dalgaard, president and CEO, SuccessFactors. “We did this through our colleagues’ passionate execution and our customers’ unwavering commitment. Global demand for our products has never been stronger. Even in a challenging economy, customers have a large appetite for products that increase revenue and decrease costs. We do both.”

SuccessFactors’ results for the fourth quarter of fiscal year 2007 were as follows:

• Q4 FY07 Revenue: Revenue was $19.2 million, an increase of 70% on a year-over-year basis and an increase of 15% on a quarter-over-quarter basis compared to the third quarter of 2007.

• Q4 FY07 Bookings: Bookings, defined as revenue plus change in total deferred revenue during the period, was $45.7 million, an increase of 69% on a year-over-year basis and an increase of 65% on a quarter-over-quarter basis compared to the third quarter of 2007.

• Q4 FY07 Customers: Customers rose approximately 350, a new record, during the quarter and totaled approximately 1,750 as of December 31, 2007, an increase of 106% from December 31, 2006, and an increase of 25% from September 30, 2007.

For the basis of GAAP and non-GAAP net loss calculations, there were 23.7 million and 43.9 million weighted average shares outstanding during the quarter, respectively. Together, these items reduced reported GAAP net loss per common share, basic and diluted, by $0.62 per share.

For the basis of GAAP and non-GAAP net loss calculations, there were 9.0 million and 38.5 million weighted average shares outstanding during the year, respectively. Together, these items reduced reported GAAP net loss per common share, basic and diluted, by $6.62 per share.
