Constant Contact is uniquely positioned to capitalize on this opportunity with our soon-to-be launched Social Campaigns product, which turns social media into a measurable, goal-oriented marketing medium for small businesses. This is a very exciting new product launch. We will further build on our product momentum with the introduction of our social CRM capabilities and delivery of our engagement marketing vision in 2012. We believe we are dramatically changing the game for small businesses.”

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, 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 is calculated by adding back stock-based compensation expense to GAAP net income, Non-GAAP net income per share is calculated by dividing Non-GAAP net income by the diluted weighted average shares outstanding.

Free cash flow is calculated by subtracting cash paid for the 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.
