Guidance

Vocus is providing, for the first time, guidance for the first quarter and full year 2012 based on information as of February 28, 2012, which includes the expected financial results of iContact from the date of acquisition:

The guidance above includes the following for the iContact acquisition, which closed on February 24^th:

For the first quarter of 2012, non-GAAP revenue, which excludes the write-down of the acquired deferred revenue, is expected to be $4.6 million. Non-GAAP EPS, which excludes stock-based compensation, amortization of intangible assets and acquisition related expenses, is expected to be $(0.01) assuming an additional 300,000 of non-GAAP weighted average diluted shares outstanding. For the full year of 2012, non-GAAP revenue, which excludes the write-down of the acquired deferred revenue, is expected to be $41.9 million. For the full year of 2012, non-GAAP EPS, which excludes stock-based compensation, amortization of intangible assets and acquisition related expenses, is expected to be $(0.04) assuming an additional 3.0 million of non-GAAP weighted average diluted shares outstanding. The acquisition is expected to reduce free cash flow for the full year of 2012 by $2.0 million. The financial impact of the acquisition on a GAAP basis cannot be estimated until the allocation of the purchase price is completed in the first quarter. Vocus currently expects that the reduction of EPS in the first quarter and the full year of 2012 will be significantly greater on a GAAP basis than on a non-GAAP basis due to the amortization of acquired intangible assets and acquisition related expenses. Please refer to section “Use of Non-GAAP Financial Measures” for further discussion of non-GAAP measures.

Use of Non-GAAP Financial Measures

Vocus provides non-GAAP measures for revenue, income from operations, net income, diluted net income per share and free cash flow as supplemental information.

We define non-GAAP revenue as GAAP revenue adjusted for the impact of the fair value adjustment to deferred revenue related to purchase accounting. Management believes the adjustment is useful to investors as a more accurate measure of our ongoing performance from the acquisitions.

We define non-GAAP income from operations as GAAP income from operations including the impact of non-GAAP revenue and excluding stock-based compensation, amortization of acquired intangible assets, fair value adjustments to contingent consideration and acquisition related expenses.

We define non-GAAP net income as GAAP net income including the impact of non-GAAP revenue and excluding stock-based compensation, amortization of acquired intangible assets, fair value adjustments to contingent consideration including the effect of foreign currencies, acquisition related expenses and income tax expense related to the valuation allowance established against a portion of deferred tax assets.

Stock-based compensation included in our GAAP financial results relates to stock option and restricted stock awards. Companies record stock-based compensation by applying varying valuation methodologies and subjective assumptions to different types of equity awards. Amortization of acquired intangible assets included in our GAAP financial results consists of amortization of non-compete agreements, trade names, purchased technology and customer relationships that are not expected to be replaced when fully amortized, as a depreciable tangible asset might. Amortization expense can vary from period to period due to the timing and size of our acquisitions. Our GAAP financial results include adjustments to the fair value of contingent consideration for acquisition earn-outs as of each reporting date from the fair value recorded on the acquisition date. Acquisition related expenses included in our GAAP general and administrative costs consists of professional fees for legal, accounting and other advisory services, integration related professional services, severance costs and retention payments incurred during the reporting period in connection with our acquired businesses. The income tax expense related to the establishment of a valuation allowance against a portion of our deferred tax assets is a non-cash expense that is not considered part of ongoing operations. It is the opinion of management that it is more likely than not that some or all of the deferred tax assets will not be realized, therefore the valuation allowance is recorded against the deferred tax assets. Management believes these non-GAAP measures allow management and investors to make meaningful comparisons between our operating results and those of the other companies, as well as provide a consistent comparison of our relative historical financial performance.

We define free cash flow as cash flow from operations less net capital expenditures, capitalized software development costs plus the excess tax benefits from equity awards and payments of contingent consideration for business acquisitions in excess of fair value on acquisition date. Management considers free cash flow to be a liquidity measure which provides useful information to management and investors regarding our ability to generate cash from operations that is available for acquisitions and other investments. Our definition of free cash flow may be different from definitions used by other companies.

Management uses non-GAAP income from operations, non-GAAP net income and free cash flow to evaluate operating performance, determine incentive compensation and to prepare operating budgets and determine the appropriate levels of capital investments. However, management believes that non-GAAP income from operations, non-GAAP net income and free cash flow are subject to material limitations since they may not be indicative of ongoing operating results. Management compensates for the limitations in the use of non-GAAP measures by also utilizing GAAP financial measures and by providing investors with a detailed reconciliation between our GAAP and non-GAAP financial results. Investors are advised to carefully review and consider this information as well as the GAAP financial results that are disclosed in our SEC filings.
