Constant Contact Announces Second Quarter 2009 Financial Results

Quarterly revenue increases 49 percent year-over-year

Email marketing customer base exceeds 304,800

WALTHAM, MA — August 6, 2009 — Constant Contact®, Inc. (NasdaqGM: CTCT), a leading provider of email marketing and online surveys for small organizations, today announced its financial results for the second quarter ended June 30, 2009.

Constant Contact reported total revenue of $31.0 million for the quarter ended June 30, 2009, an increase of 49% compared to revenue of $20.8 million for the comparable period in 2008. Constant Contact ended the second quarter of 2009 with over 304,800 email marketing customers, an increase of 47% compared to the end of the second quarter of 2008.

“Constant Contact delivered revenue, adjusted EBITDA and net income per share that were above our guidance for the second quarter. We also added approximately 24,000 net new email marketing subscribers in the second quarter, as we moved into the beginning of our seasonally slower period,” said Gail Goodman, CEO of Constant Contact. “In spite of the difficult economic environment, we continue to expect Constant Contact to deliver 2009 revenue growth of more than 45%, which we believe is best-in-class. We are also preparing to launch our third major product offering, which we believe will provide further value to our existing customer base and expand our overall addressable market opportunity.”

Constant Contact reported an operating loss of $121,000 for the quarter ended June 30, 2009, compared to an operating loss of $1.1 million for the comparable period in 2008. Constant Contact reported adjusted EBITDA of $3.1 million in the second quarter of 2009, an increase of 246% compared to adjusted EBITDA of $894,000 in the comparable period in 2008.

Adjusted EBITDA is a non-GAAP financial measure that is calculated by taking GAAP net income (loss), adding depreciation and amortization and stock-based compensation, then subtracting interest income. Adjusted EBITDA margin is equal to adjusted EBITDA divided by revenue. A reconciliation of the most comparable GAAP financial measure to the non-GAAP measure used above is included with the financial tables at the end of this release.

Constant Contact reported GAAP net income of $39,000 for the second quarter of 2009, as compared to a GAAP net loss of $389,000 for the comparable period in 2008. Constant Contact reported break even GAAP net income per share for the second quarter of 2009, as compared to a GAAP net loss per share of $0.01 for the comparable period in 2008.

Second quarter 2009 non-GAAP net income per share was $0.04, compared to non-GAAP net income per share of $0.01 for the same period in 2008. Non-GAAP net income per share is a non-GAAP financial measure that is calculated by adding back stock-based compensation expense to GAAP net income (loss) and dividing this total by the weighted average shares outstanding, using diluted weighted average shares outstanding in the case of non-GAAP net income, and basic weighted average shares outstanding in the case of non-GAAP net loss. A reconciliation of the most comparable GAAP financial measure to

the non-GAAP measure used above is included with the financial tables at the end of this release.

“During the second quarter, the company again delivered better-than-expected adjusted EBITDA; a record performance from both an absolute dollars and margin perspective,” said Steven R. Wasserman, vice president and chief financial officer of Constant Contact. “We continue to test many new marketing programs and expect to re-launch national radio as we near the end of the third quarter. We are modestly raising our full year adjusted EBITDA target based on the company’s strong first half performance, however we remain committed to our strategy of reinvesting adjusted EBITDA margin in excess of our annual target into initiatives that we believe will enhance our long-term growth profile.”

Other Second Quarter Highlights

• Added over 23,900 net new email marketing customers, bringing total email marketing customers to over 304,800.

• Maintained consistency in its key customer metrics. The average email marketing invoice remained in the $33 range, plus or minus two dollars.

• Continued to build out the company’s network of channel partners, ending the quarter with over 4,400 active channel partners, up from 4,000 at the end of the first quarter.

Business Outlook

Based on information available as of August 6, 2009, Constant Contact is issuing guidance for the third quarter and full year 2009 as follows:

Third Quarter 2009: The Company expects third quarter revenue to be in the range of $33.3 million to $33.5 million, adjusted EBITDA to be in the range of $3.4 million to $3.6 million, and non-GAAP net income per share to be in the range of $0.04 to $0.05 based on weighted average shares outstanding (diluted) of 29.6 million shares.

GAAP net income is expected to be in the range of break even to $200,000 and GAAP net income per share to be in the range of $0.00 to $0.01. GAAP net income per share is based on weighted average shares outstanding (diluted) of 29.6 million shares and includes an estimated stock-based compensation expense of $1.3 million.

Full Year 2009: The Company expects full year 2009 revenue to be in the range of $127.5 million to $130 million. The Company expects adjusted EBITDA to be in the range of $10.3 million to $10.7 million. The Company expects full year 2009 non-GAAP net income per share to be in the range of $0.07 to $0.08 based on weighted average shares outstanding (diluted) of 29.5 million shares.

The Company expects GAAP net loss to be in the range of $2.8 million to $3.1 million, and GAAP net loss per share to be in the range of $0.10 to $0.11. GAAP net loss per share is based on weighted average shares outstanding (basic) of 28.3 million shares and includes an estimated stock-based compensation expense of $5.2 million.

Non-GAAP Financial Measures

This press release contains five non-GAAP financial measures: adjusted EBITDA, adjusted EBITDA margin, non-GAAP net income, non-GAAP net income per share and free cash flow. 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 incentive compensation, and for budgeting and planning purposes. These measures are used in monthly financial reports prepared for management and in 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 of the Company 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 measures used in this press release are included with the financial tables at the end of this release.
