SAN MATEO, Calif. — April 30, 2009 — SuccessFactors, Inc. (NASDAQ: SFSF), the global leader in on-demand performance and talent management solutions, today announced results for its first fiscal quarter of 2009 which ended March 31, 2009.

“Q1 was a challenging quarter for SuccessFactors, as businesses of all sizes and industries slowed their decision-making and reduced spending on software products and services. Our market was no exception. In the face of this challenging environment, I am proud to report that our team delivered year-over-year revenue growth of 50% in Q1, while improving non-GAAP gross margin by 26% year-over-year, and non-GAAP operating margin by 88%, compared to Q1 2008. We have also sustained our commitment to cash flow positive operations, with positive non-GAAP cash flow of $2.7 million for Q1, improving cash flow 4X over the previous quarter,” said Lars Dalgaard, chief executive officer for SuccessFactors.

“As we said to you in February, we view this economic environment as an appropriate time to increase our focus on expense management and profitability, while continuing to invest in the highest levels of product quality, support, and total value for our customers,” Dalgaard continued. “While we have maintained the highest revenue growth rate in our industry through the recession that began in 2007, we believe that these investments, coupled with a steady improvement in profitability, will enable us to continue to outperform our market when this recession is over.”

SuccessFactors’ results for the first quarter fiscal year 2009:

• Q1 FY09 Revenue: Q109 revenue was $35.2 million, compared to prior guidance of $34.0 million to $34.5 million, and compared to $23.5 million for the same period last year, an increase of 50% year-over-year, and an increase of 7% sequentially from Q408.

• Q1 FY09 Cash Flows Generated from Operations: For the quarter ended March 31, 2009, the company generated approximately $2.7 million of cash from operating activities, compared to the $4.0 million use in the quarter ended March 31, 2008, and an increase of 286% sequentially from the $0.7 million generated in Q408. Total cash, cash equivalents and marketable securities at March 31, 2009 was $105.5 million.

• Q1 FY09 Net Loss per Share: On a GAAP basis, for the quarter ended March 31, 2009, the net loss per common share, basic and diluted, was $0.10. The non-GAAP net loss per common share, basic and diluted, was $0.06, which excludes approximately $2.4 million in stock-based compensation expense, compared to a non-GAAP net loss per share, basic and diluted, of $0.06 in Q408 and $0.34 in Q108, an improvement of 82% year-over-year. GAAP and non-GAAP net loss per common share calculations are based on 56.3 million weighted average shares outstanding during the first quarter of 2009.

Use of Non-GAAP Financial Information

SuccessFactors provides quarterly and annual financial statements that are prepared in accordance with generally accepted accounting principles (GAAP). To help understand SuccessFactors’ past financial performance and future results, SuccessFactors has supplemented its financial results that it provides in accordance with GAAP, with non-GAAP financial measures. The method SuccessFactors uses to produce non-GAAP financial results is not computed according to GAAP and may differ from the methods used by other companies. The non-GAAP measures used by SuccessFactors exclude the impact of stock-based compensation expense recorded under SFAS 123(R). SuccessFactors’ reference to these non-GAAP financial results should be considered in addition to results that are prepared under current accounting standards but should not be considered as a substitute for, or superior to, the financial results that are presented as consistent with GAAP. SuccessFactors’ management uses the supplemental non-GAAP financial measures internally to understand, manage and evaluate SuccessFactors’ business and make operating decisions. These non-GAAP financial measures are among the factors SuccessFactors’ management uses in planning for and forecasting future periods. Reconciliation to the nearest GAAP financial measures of the non-GAAP financial measures is included in this press release.
