Responsys Announces Fourth Quarter 2011 Results

SAN BRUNO, Calif., Feb. 28, 2012 (GLOBE NEWSWIRE) -- Responsys, Inc. (Nasdaq:MKTG), the leading provider of email and cross-channel marketing solutions, today announced financial results for the fourth quarter and fiscal year ended December 31, 2011.

"We are pleased with our fourth quarter performance," said Dan Springer, CEO and Chairman of Responsys. "Our customers' marketing activities were robust in the period, driving solid messaging volumes and revenue ahead of our guidance. EPS was also ahead of our guidance, reflecting both strong revenue and lower-than-planned spend in certain areas. Our growth continues to be influenced by the strong need for marketing organizations to be able to market to their customers across the digital channels of email, social, mobile, the web and display."

For the fourth quarter of 2011, total revenue increased 21% to $37.2 million, up from $30.7 million in the fourth quarter of 2010.

Subscription revenue for the fourth quarter of 2011 was $26.7 million, up 20% as compared to $22.3 million in the fourth quarter of 2010. Professional services revenue for the fourth quarter of 2011 was $10.5 million, up 26% as compared to $8.3 million in the fourth quarter of 2010.

GAAP net income for the fourth quarter of 2011 was $2.0 million compared to $5.5 million in the fourth quarter of 2010. GAAP net income attributable to common stockholders for the fourth quarter of 2011 was $2.0 million, or $0.04 per share on a diluted basis. This compares to GAAP net income attributable to common stockholders for the fourth quarter of 2010 of $1.4 million, or $0.09 per share on a diluted basis. GAAP net income attributable to common stockholders is computed after determining the net income allocable to preferred stockholders prior to their conversion into common stock in conjunction with the IPO.

Non-GAAP net income for the fourth quarter of 2011 was $3.3 million, or $0.06 per share on a non-GAAP diluted basis¹, as compared to non-GAAP net income of $5.3 million, or $0.12 per share on a non-GAAP diluted basis¹, for the fourth quarter of 2010. A reconciliation of the comparable GAAP to non-GAAP financial measures used in this press release is included in the attached tables.

For fiscal 2011, revenue was $134.9 million, up 43% as compared to $94.1 million in 2010. Subscription revenue was $94.5 million, up 36%, and professional services revenue was $40.4 million, up 63%. 

GAAP net income for 2011 was $8.0 million compared to $8.6 million in 2010. GAAP net income attributable to common stockholders for 2011 was $5.2 million, or $0.12 per share on a diluted basis. This compares to GAAP net income attributable to common stockholders in 2010 of $1.2 million, or $0.08 per share on a diluted basis. 

Non-GAAP net income was $11.0 million in 2011, or $0.21 per share on a non-GAAP diluted basis¹, compared to non-GAAP net income of $9.6 million in 2010, or $0.22 per share on a non-GAAP diluted basis¹.

Non-GAAP Financial Measures

This press release contains non-GAAP financial measures including non-GAAP operating income, non-GAAP net income, and non-GAAP net income per share on a diluted basis¹. Non-GAAP operating income, non-GAAP net income, and non-GAAP net income per share on a diluted basis¹ exclude the amortization of acquired intangible assets, stock-based compensation expense, the gain on the acquisition of Eservices, and the fair value adjustments for call and put options related to Eservices, net of related income tax effects, as applicable. Non-GAAP net income per share on a diluted basis¹ is not adjusted for the impact of unamortized stock-based compensation on the computation of diluted shares under GAAP. The Company believes that these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to the Company's financial condition and results of operations. The Company's management uses these non-GAAP measures to compare the Company's performance to that of prior periods and uses these measures in financial reports prepared for management and the Company's board of directors. The Company believes that the use of these non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing the Company's financial measures with other software-as-a-service companies, many of which present similar non-GAAP financial measures to investors.

The Company does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant elements that are required by GAAP to be recorded in the Company's financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management in determining these non-GAAP financial measures. In order to compensate for these limitations, management of the Company presents its non-GAAP financial measures in connection with its GAAP results. The Company urges investors to review the reconciliation of its non-GAAP financial measures to the comparable GAAP financial measures, which is included in this press release, and not to rely on any single financial measure to evaluate the Company's business.

Forward Looking Statements
