SAN BRUNO, Calif., Aug. 6, 2012 (GLOBE NEWSWIRE) -- Responsys, Inc. (Nasdaq:MKTG), a leading provider of email and cross-channel marketing solutions, today announced financial results for the quarter ended June 30, 2012.

"We had a solid second quarter. Heading into the second half of the year, we are pleased with our business momentum and the increased traction we are seeing from our investments in sales and marketing. As we have said the past couple of quarters, we expect revenue growth to accelerate in the second half of the year, and this is reflected in our second half guidance," said CEO Dan Springer.

Springer continued, "Three key factors are driving our growth: the continued expansion of digital consumer behaviors, the continued proliferation of cloud computing-based platforms, and the growing recognition among businesses that they need to upgrade their own marketing approach to catch up with existing customer expectations and behaviors. We continue to be excited by the high level of marketing success that our customers are achieving as well as the strong interest in expanding that success into channels like mobile, social and display, which we saw from the over 1,300 clients that attended our U.S. and EMEA Interact conferences in May and June."

For the second quarter of 2012, total revenue increased 17.5% to $39.5 million, up from $33.7 million in the second quarter of 2011.

Subscription revenue for the second quarter of 2012 was $27.5 million, up 19.7% as compared to $22.9 million in the second quarter of 2011. Professional services revenue was $12.1 million, up 12.8% as compared to $10.7 million in the second quarter of 2011.

GAAP net income for the second quarter of 2012 was breakeven. This compares to GAAP net income of $2.5 million and diluted GAAP net income attributable to common stockholders of $1.8 million in the second quarter of 2011. Net income per share attributable to common stockholders in the second quarter of 2012 was $0.00 per share on a diluted basis, as compared to $0.04 in the second quarter of 2011.

For the six months ended June 30, 2012, total revenue increased 21.6% to $77.6 million, up from $63.8 million in the six months ended June 30, 2011.

Subscription revenue for the first half of 2012 was $54.7 million, up 24.4% as compared to $43.9 million in the first half of 2011. Professional services revenue was $22.9 million, up 15.4% as compared to $19.9 million in the first half of 2011.

GAAP net income for the first half of 2012 was $2.1 million. This compares to GAAP net income of $4.6 million and diluted GAAP net income attributable to common stockholders of $1.8 million for the first half of 2011. Net income per share attributable to common stockholders in the first half of 2012 was $0.04 per share on a diluted basis, as compared to $0.06 in the first half of 2011. GAAP net income for the six months ended June 30, 2011 includes a $2.2 million pretax gain on the acquisition of Eservices ($1.3 million after tax).

In addition to using GAAP results in evaluating Responsys' business, management believes it is useful to also measure results using non-GAAP net income, which is net income excluding stock-based compensation expense, amortization of acquired intangible assets, the gain on the acquisition of Eservices, and related income tax effects, as applicable.

Non-GAAP net income for the second quarter of 2012 was $1.4 million, or $0.03 per diluted share as compared to $3.4 million, or $0.07 per share on a non-GAAP diluted basis¹, for the second quarter of 2011. 

Non-GAAP net income for the six months ended June 30, 2012 was $4.9 million, or $0.09 per diluted share as compared to $5.1 million, or $0.10 per share on a non-GAAP diluted basis¹, for the six months ended June 30, 2011. 

A reconciliation of the comparable GAAP to non-GAAP financial measures used in this release is included in the attached tables.

Non-GAAP Financial Measures

This press release contains non-GAAP financial measures including non-GAAP net income, and non-GAAP net income per share on a diluted basis¹. 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 related tax effects. Non-GAAP net income per share on a diluted basis 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 judgments 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

The financial projections under Business Outlook, and other forward-looking statements included in this release, reflect management's best judgment based on factors currently known and involve risks and uncertainties; our actual results may differ materially from those discussed here. These risks and uncertainties include: our ability to acquire and retain customers; whether customers purchase additional functionality and increase their usage; pricing pressures and competitive factors; the uncertain impact of overall global economic conditions, including on customers, prospective customers and partners, renewal rates and length of sales cycles; the fact that the market for cross-channel marketing solutions is at an early stage of development and may not develop as rapidly as we anticipate; outages or security breaches; our ability to develop, and market acceptance of, new products and services; the impact of any discovered product defects; our ability to manage our growth, both domestically and internationally; our ability to successfully expand our sales force and its effectiveness; our ability to maintain profitability; and other risks detailed from time to time in our SEC reports including, but not limited to, our most recent annual report on Form 10-K and most recent quarterly report on Form 10-Q. The Company disclaims any intention or obligation to publicly update or revise any forward-looking statements including any guidance, whether as a result of events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.

¹ Non-GAAP net income per share attributable to common stockholders was derived by dividing by the corresponding non-GAAP basic and non-GAAP diluted weighted-average shares outstanding. Non-GAAP weighted-average shares outstanding was computed to give effect to the conversion of the Series A, Series B, Series C, Series D, and Series E convertible preferred stock using the as-if converted method into common shares as though the conversion had occurred as of the beginning of the period.
