SuccessFactors Announces
Fourth Quarter and Fiscal 2008 Results

Total 2008 Revenues Grow 77%, While Improving Operating Margins By 99%,
and Achieving Cash Profitability in Q4

• Company achieves cash profitability (positive cash flow from operations) in Q408

• Guidance of 30% revenue growth and ongoing quarterly cash profitability

• Company becomes one of the largest SaaS providers exceeding 4.5 million global users and adding more than 1.5 million users in 2008

SAN MATEO, Calif. — February 9, 2009 — SuccessFactors, Inc. (NASDAQ: SFSF), the global leader in on-demand performance and talent management solutions, today announced financial results for its fourth quarter and fiscal 2008 which ended December 31, 2008.

“SuccessFactors continues to deliver Software-as-a-Service (SaaS) leading revenue growth of 77% year-over-year,” said Lars Dalgaard, chief executive officer for SuccessFactors. “We achieved cash profitability 9 months ahead of our original target. In the recessionary environment, SuccessFactors has proven we have the ability to act quickly and nimbly, always focused on building a highly profitable company. Now with greater than $125 million in an annual recurring revenue base, we continue to maintain customer focus, producing a record 1,000 go-lives in 2008. In just 90 days, we were able to increase non-GAAP gross margin above 70% for the first time, from 67% to 71%, and up 18 full percentage points from 53% in Q407. We also were able to improve non-GAAP operating margin by 51 full percentage points from minus 61% in Q308 and by 99 full percentage points in total for 2008 from minus 109% in Q407 to minus 10% in Q408 - putting GAAP profitability on the horizon.”

“SuccessFactors has the largest individual SaaS deployments and the largest user base, with more than 4.5 million paying and unique users across 185 countries, up a record 1.5 million users in 2008. Our customers around the world in more than 60 industries are improving their businesses and driving increased shareholder value through increased employee alignment, motivation, and collaboration. Despite that, there remain more than a billion workers that can be monetized, which is why SuccessFactors continues to invest in this huge opportunity, having only penetrated less than 0.25% of a potential multi-billion dollar market. SuccessFactors has the leadership position to unlock this value.”

SuccessFactors’ results for the fourth quarter and fiscal year 2008:

“Our guidance shows we expect healthy revenue growth during a period when many software companies are showing negative growth,” said Bruce Felt, chief financial officer for SuccessFactors. “We have begun to moderate our spending in favor of reaching our profitability targets sooner, and we remain significantly invested in the strategic talent management category we created. As our guidance reflects, we remain cautiously optimistic about 2009 and expect to achieve annual revenue growth and an improved bottom line at the same time.”

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.
