CONSTANT CONTACT, INC.

UNAUDITED PRO FORMA COMBINED CONSOLIDATED STATEMENTS OF OPERATIONS

On June 12, 2012, Constant Contact, Inc., a Delaware corporation (“Constant Contact” or the “Company”), SinglePlatform, Corp., a Delaware corporation (“SinglePlatform”), Match Acquisition Corporation, a Delaware corporation and wholly-owned subsidiary of Constant Contact (“Merger Sub”), and Shareholder Representative Services LLC, a Colorado limited liability company, solely in its capacity as Stockholder Representative, entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the Merger Agreement, also on June 12, 2012, Merger Sub was merged with and into SinglePlatform, with SinglePlatform continuing as the surviving corporation and a wholly-owned subsidiary of Constant Contact (the “Merger”). The Merger Agreement provided for a cash purchase price of $65 million, which was adjusted to reflect SinglePlatform’s working capital deficit at the acquisition date and other transaction expenses as provided for by the Merger Agreement, such that the cash payment at the time of closing was $63.0 million. The cash purchase price is subject to further adjustment for certain working capital adjustments, which are identified by the Company within 90 days of the acquisition date. The Merger Agreement also provided for an additional amount of up to $30 million in earn-out payments based upon SinglePlatform meeting certain revenue targets over the next two years, to be measured in six-month intervals. The Merger Agreement also contains customary representations, warranties and indemnities of SinglePlatform and Constant Contact.

The unaudited pro forma combined consolidated statements of operations, referred to herein as the “Pro Forma Financial Statements” should be read in conjunction with:

The Pro Forma Financial Statements for the year ended December 31, 2011 and for the three months ended March 31, 2012 have been adjusted for the operational results of SinglePlatform, Corp. as if the merger had occurred on January 1, 2011.

The Company has not provided a pro forma combined consolidated balance sheet as of March 31, 2012 because the merger of SinglePlatform is reflected in the Company’s unaudited condensed consolidated balance sheet as of June 30, 2012 included in the Company’s Quarterly Report on Form 10-Q for the three months ended June 30, 2012 and filed with the SEC on August 1, 2012.

The Pro Forma Financial Statements are presented for illustrative purposes and do not purport to represent what the results of operations would actually have been if the merger occurred as of the date indicated or what such results would be for any future periods.

The following table summarizes the preliminary purchase price for SinglePlatform and the preliminary allocation of the purchase price:

The preliminary purchase price included cash consideration of $65,000 adjusted for SinglePlatform’s working capital deficit and certain transaction expenses as described in the Merger Agreement such that the preliminary cash payment at the time of closing was $63,048. The cash consideration is subject to further adjustment for certain working capital adjustments, which are identified by the Company within 90 days of the acquisition date. These adjustments, if any, will affect the final amount of the purchase price and the allocation of that purchase price to the working capital accounts. The amounts assigned to SinglePlatform’s tangible and intangible assets and liabilities acquired are based on their respective fair values determined as of the merger date. The excess of the purchase price over the fair value of net assets acquired is recorded as goodwill. In accordance with current accounting standards, the goodwill will not be amortized, but rather will be tested for impairment annually or more frequently if facts and circumstances warrant a review.

Pro forma adjustments reflect only those adjustments which are directly attributable to the Merger, factually supportable and expected to have a continuing impact to the Company. The unaudited pro forma combined consolidated statements of operations reflect the effect of the following pro forma adjustments:

4

The Company amortizes the intangible assets over the estimated useful lives noted above. For the developed technology and publisher relationship assets, as the pattern of consumption of the economic benefits of the intangible assets cannot be reliably determined, the Company amortizes these acquired intangible assets over their estimated useful lives on a straight-line basis. The Company also amortizes the trade name asset over its estimated useful life on a straight-line basis as the straight-line basis is not materially different than the pattern of consumption of economic benefit basis. Customer relationships are amortized over their useful life based on the pattern of consumption of economic benefit of the asset. Amortization commences once the asset has been placed in service.
