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, estimated cash tax rate and free cash flow.

Adjusted EBITDA is a non-GAAP financial measure that is defined as GAAP net income (loss) before income taxes, interest and other income (expense), net, depreciation and amortization, stock-based compensation, litigation contingency accruals and contingent consideration adjustments. Adjusted EBITDA margin is a non-GAAP financial measure that is calculated by dividing adjusted EBITDA by revenue.

Non-GAAP net income is a non-GAAP financial measure that is defined as GAAP net income (loss) before the non-cash portion of income taxes, stock-based compensation expense, litigation contingency accruals and contingent consideration adjustments. Non-GAAP net income per share is a non-GAAP financial measure that is calculated by dividing non-GAAP net income (loss) by the weighted average shares outstanding.

Estimated cash tax rate is calculated by dividing estimated taxes to be paid by estimated full year income before taxes.

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.

Page 4

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.

Other Financial Information

The results above and the financial tables below have been revised to correct a non-cash expense associated with income taxes, which was immaterial to the company’s prior financial statements. Previously reported income tax expense for the first quarter of 2013, the second quarter of 2013, and the third quarter of 2013 was increased $194 thousand, $181 thousand, and $106 thousand, respectively. Previously reported income tax expense for the three months ended December 31, 2012 and the year ended December 31, 2012 was increased $156 thousand and $190 thousand, respectively. The financial information in this press release reflects the revision, which will also be reported in the company’s Annual Report on Form 10-K for the year ended December 31, 2013.
