2010 revenue increases 35% and adjusted EBITDA margin expands to record 13%
Quarterly revenue increases 30% year-over-year
Quarterly adjusted EBITDA increases 250% year-over-year

WALTHAM, MA — February 3, 2011 — Constant Contact®, Inc. (Nasdaq: CTCT), a leading provider of email marketing, event marketing, social media marketing and online survey tools for small organizations, today announced its financial results for the fourth quarter and full year ended December 31, 2010.

“Constant Contact delivered another strong quarter, with better-than-expected revenue and profitability leading to full year 2010 results that were above our original and most recent financial guidance,” said Gail Goodman, CEO of Constant Contact. “Our combination of easy-to-use marketing tools and our award winning customer support, education and personal coaching provides an unparalleled value proposition for small businesses. This enabled Constant Contact to deliver 35 percent revenue growth for 2010, one of the fastest growth rates of any publicly traded SaaS company. We accomplished this in the midst of a difficult economic environment for small businesses.”

Goodman added, “We are evolving from an email marketing company to a broader marketing platform allowing small organizations to engage their audiences in many ways and across many channels. As we continue to expand and evolve our product offerings we believe we further distance Constant Contact from the competition and create new opportunities to drive growth. We have never been more excited about Constant Contact’s long-term opportunity and market position.”

Non-GAAP Financial Measures

This press release contains the following non-GAAP financial measures: adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, non-GAAP net income per share, non-GAAP net loss, non-GAAP net loss per share and free cash flow.

Adjusted EBITDA is calculated by taking GAAP net income (loss), adding depreciation and amortization, stock-based compensation, adjusting for taxes, then subtracting interest and other income. Adjusted EBITDA margin is equal to adjusted EBITDA divided by revenue.

Non-GAAP net income per share is calculated by adding back stock-based compensation expense to GAAP net income (loss) and dividing this total by the weighted average shares outstanding.

Free cash flow is calculated by subtracting acquisition of property and equipment from net cash provided by operating activities.

Constant Contact believes that these non-GAAP measures of financial results provide useful information to management and investors regarding certain financial and business trends relating to Constant Contact’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 for trend analyses, for purposes of determining executive and senior management incentive compensation and for budgeting and planning purposes. These measures are used in monthly financial reports prepared for management and in monthly and quarterly financial reports presented to 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.

Management of 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 expenses and income 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 about which expenses and income are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, management presents non-GAAP financial measures in connection with GAAP results. Constant Contact urges investors to review the reconciliation of its non-GAAP financial measures to the comparable GAAP financial measures, which it includes in press releases announcing quarterly financial results, including this press release, and not to rely on any single financial measure to evaluate the company’s business.

Reconciliation tables of the most comparable GAAP financial measures to the non-GAAP financial measures used in this press release are included with the financial tables at the end of this release.
